PROSPECTUS OF

GRANITE CONSTRUCTION INCORPORATED

May 15, 2018

PROPOSED MERGER—YOUR VOTE IS VERY IMPORTANT

Dear Layne Stockholders:

You are cordially invited to attend a special meeting of the stockholders of Layne Christensen Company, a Delaware corporation (“Layne”), which will be held at 9:00 a.m. (Central Time), on June 13, 2018 located at 1800 Hughes Landing Boulevard, Ste. 700, The Woodlands, TX 77380 (the “Special Meeting”).

Layne, Granite Construction Incorporated, a Delaware corporation (“Granite”), and Lowercase Merger Sub Incorporated (“Merger Sub”), a Delaware corporation and a wholly owned subsidiary of Granite, have entered into an Agreement and Plan of Merger, dated as of February 13, 2018 (the “Merger Agreement”), pursuant to which, among other things, Merger Sub will be merged with and into Layne, with Layne surviving the merger as a wholly owned subsidiary of Granite (the “Merger”). The board of directors of each of Granite and Layne has unanimously approved the Merger.

If the Merger is completed, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01 per share, of Layne (“Layne Common Stock”) that is issued and outstanding will be cancelled and automatically converted into the right to receive 0.27 shares of common stock, par value $0.01 per share, of Granite (“Granite Common Stock”).

Upon completion of the Merger, former Layne stockholders will own about 5,435,720 shares, or approximately 12% of the outstanding shares, of Granite Common Stock on a fully diluted basis (excluding any shares that may subsequently be issued in connection with any conversion of the 8.0% Convertible Notes into shares of Granite Common Stock following the Merger). No fractional shares will be issued in the Merger. Layne’s stockholders will receive cash in lieu of any fractional shares.

At the Special Meeting, Layne stockholders will be asked to adopt the Merger Agreement, and approve other related proposals. Information about the Special Meeting, the Merger and other related business to be considered by Layne stockholders at the Special Meeting is included in this proxy statement/prospectus. We urge all Layne stockholders to read this proxy statement/prospectus, including the annexes, and the Layne and Granite filings incorporated by reference into this proxy statement/prospectus carefully and in their entirety. In particular, we urge you to read carefully the Risk Factors beginning on page 22.

Your vote is very important regardless of the number of shares of Layne Common Stock that you own. The Merger cannot be completed without the adoption of the Merger Agreement by the affirmative vote of a majority of the outstanding shares of Layne Common Stock entitled to vote at the Special Meeting. Whether or not you plan to attend the Special Meeting, please vote as soon as possible by following the instructions in this proxy statement/prospectus to make sure that your shares are represented at the Special Meeting. Your failure to vote your shares of Layne Common Stock at the Special Meeting will have the same effect as a vote against the proposal to adopt the Merger Agreement. The Board of Directors of Layne unanimously recommends that you vote “FOR” the adoption of the Merger Agreement and “FOR” the other proposals described in this proxy statement/prospectus.

Shares of Layne Common Stock are listed on the Nasdaq Global Select Market under the symbol “LAYN.” Shares of Granite Common Stock are listed on the New York Stock Exchange under the symbol “GVA.” We urge you to obtain current market quotations for shares of Layne Common Stock and Granite Common Stock.

We appreciate your continued support and interest in Layne.

Sincerely yours,

Notice of Special Meeting of Stockholders

To be Held on June 13, 2018

To the Stockholders of Layne Christensen Company:

Notice is hereby given that a special meeting of stockholders of Layne Christensen Company (“Layne”) will be held on June 13, 2018 at 9:00 a.m. (Central Time), located at 1800 Hughes Landing Boulevard, Ste. 700, The Woodlands, TX 77380 (the “Special Meeting”), for the following purposes:

to adopt the Agreement and Plan of Merger (the “Merger Agreement”), dated as of February 13, 2018, by and among Layne, Granite Construction Incorporated (“Granite”) and Lowercase Merger Sub Incorporated (“Merger Sub”), pursuant to which Merger Sub will be merged with and into Layne, with Layne surviving as a wholly owned subsidiary of Granite;

to approve, on a non-binding, advisory basis, the compensation payments that will or may be paid by Layne to its named executive officers in connection with the Merger (the “compensation proposal”); and

to approve any proposal to adjourn the Special Meeting, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, sufficient votes to adopt the Merger Agreement have not been obtained by Layne (the “adjournment proposal”).

Approval of the proposal to adopt the Merger Agreement is required for completion of the Merger. Neither the compensation proposal nor the adjournment proposal is a condition to the obligations of Layne or Granite to complete the Merger.

Layne will transact no other business at the Special Meeting except for the proposals set forth above or such other business as may properly be brought before the Special Meeting or any adjournment or postponement thereof. Please refer to this proxy statement/prospectus, which also includes a copy of the Merger Agreement as Annex A, for further information with respect to the business to be transacted at the Special Meeting.

The Board of Directors of Layne has set May 11, 2018 as the record date (the “Record Date”) for the Special Meeting. Only Layne stockholders of record at the close of business on the Record Date may vote at the Special Meeting and any adjournments thereof. A list of Layne stockholders entitled to vote at the Special Meeting will be available for inspection at Layne’s offices in The Woodlands, Texas for any purpose relevant to the Special Meeting during normal business hours for a period of ten days before the Special Meeting and at the Special Meeting. We urge you to read carefully this proxy statement/prospectus in its entirety, including the Annexes and the documents incorporated by reference herein.

The approval of the proposal to adopt the Merger Agreement requires the affirmative vote of the holders of a majority of the outstanding shares of Layne Common Stock entitled to vote at the Special Meeting. The compensation proposal and the adjournment proposal each require the affirmative vote of a majority of the votes cast “FOR” or “AGAINST” by the Layne stockholders present in person or represented by proxy at the Special Meeting and entitled to vote on such proposal, although the compensation proposal vote will not be binding on Layne. Abstentions will have the same effect as a vote against the proposal to adopt the Merger Agreement. Abstentions will have no effect on the adjournment proposal and compensation proposal. The Board of

Directors of Layne has unanimously approved the Merger Agreement and the transactions contemplated thereby and recommends that you vote “FOR” each of these proposals.

By Order of the Board of Directors,

QUESTIONS AND ANSWERS

The questions and answers below highlight only selected information from this proxy statement/prospectus and are intended to briefly address some commonly asked questions about, among other things, the Special Meeting, the Merger Agreement and the Merger. The Layne Board is soliciting proxies from its stockholders to vote at the Special Meeting, to be held at 9:00 a.m. (Central Time), on June 13, 2018 located at 1800 Hughes Landing Boulevard, Ste. 700, The Woodlands, TX 77380, and any adjournment or postponement of the Special Meeting.

These questions and answers do not contain all of the information that may be important to you. You should carefully read this entire proxy statement/prospectus and the additional documents incorporated by reference into this proxy statement/prospectus to fully understand the matters to be acted upon and the voting procedures for the Special Meeting. You may obtain the information incorporated by reference into this proxy statement/prospectus without charge by following the instructions under “Where You Can Find More Information” beginning on page 145 of this proxy statement/prospectus.

Q:	Why have I received this proxy statement/prospectus?

You are receiving this proxy statement/prospectus because you were a stockholder of record of Layne on May 11, 2018, the Record Date for the Special Meeting. On February 13, 2018, each of the Granite Board and the Layne Board unanimously approved the Merger Agreement, pursuant to which Layne will become a wholly owned subsidiary of Granite. A copy of the Merger Agreement is attached to this proxy statement/prospectus as Annex A, which Granite and Layne encourage you to review.

Your vote is important. In order to complete the Merger, Layne stockholders must vote to adopt the Merger Agreement. Adoption of the Merger Agreement requires the affirmative vote of the holders of a majority of the issued and outstanding shares of Layne Common Stock entitled to vote on this proposal.

This proxy statement/prospectus is being delivered to you as both a proxy statement of Layne and a prospectus of Granite. It is a proxy statement because the Layne Board is soliciting proxies from Layne stockholders to vote on the adoption of the Merger Agreement at the Special Meeting as well as the other matters set forth in the notice of the Special Meeting and described in this proxy statement/prospectus, and your proxy will be used at the Special Meeting or at any adjournment or postponement of the Special Meeting. It is a prospectus because Granite will issue Granite Common Stock to Layne stockholders in the Merger. On or about May 15, 2018, Layne intends to begin to deliver to its stockholders of record as of the close of business on the Record Date printed copies of these materials.

Q:	What are the specific proposals on which I am being asked to vote at the Special Meeting?

A:	Layne stockholders are being asked to vote on:

•

a proposal to adopt the Merger Agreement, pursuant to which Merger Sub will merge with and into Layne, with Layne surviving the Merger as a wholly owned subsidiary of Granite;

•

a proposal to approve, on a non-binding, advisory basis, the compensation payments that will or may be paid by Layne to its named executive officers in connection with the Merger, which we refer to herein as the compensation proposal; and

•

a proposal to approve any proposal to adjourn the Special Meeting, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, sufficient votes to adopt the Merger Agreement have not been obtained by Layne, which we refer to herein as the adjournment proposal.

The adoption by Layne stockholders of the Merger Agreement is a condition to the consummation of the Merger. Neither the approval of the compensation proposal nor the approval of the Layne adjournment proposal is a condition to the Merger.

- 1 -

Q:	What will I receive for my shares of Layne Common Stock in the Merger?

A:	In the Merger, each share of Layne Common Stock issued and outstanding immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive 0.27 shares of Granite Common Stock. You will receive cash in lieu of any fractional share.

You will own shares of Granite Common Stock and will no longer own shares in Layne following the Merger. See “The Merger Agreement” beginning on page 105 of this proxy statement/prospectus.

Q:	Where will the shares of Granite Common Stock that I receive in the Merger be traded?

A:	Shares of Granite Common Stock are traded on NYSE under the symbol “GVA.” Granite will apply to have the new shares of Granite Common Stock issued in the Merger listed on NYSE upon consummation of the Merger.

Q:	How does the Layne Board recommend that Layne stockholders vote?

At a meeting duly called and held on February 13, 2018, the Layne Board unanimously determined that the Merger Agreement and the Merger were in the best interests of Layne and its stockholders. The Layne Board unanimously recommends that Layne stockholders vote “FOR” the proposal to adopt the Merger Agreement, “FOR” the compensation proposal and “FOR” the adjournment proposal. See “The Merger— Layne Board Recommendation and its Reasons for the Merger” beginning on page 78 of this proxy statement/prospectus.

Q:	When and where is the Special Meeting?

A:	The Special Meeting will be held at 9:00 a.m. (Central Time), on June 13, 2018 located at 1800 Hughes Landing Boulevard, Ste. 700, The Woodlands, TX 77380. For additional information about the Special Meeting, see “The Special Meeting” beginning on page 51 of this proxy statement/prospectus.

Q:	What is a quorum for purposes of the Special Meeting?

A quorum of outstanding shares of Layne Common Stock is necessary to take action at the Special Meeting. Holders of a majority of the outstanding shares of Layne Common Stock entitled to vote as of the Record Date must be present, in person or by proxy, at the Special Meeting to constitute a quorum and to conduct business at the Special Meeting. Your shares are counted as present if you attend the Special Meeting in person or properly vote by telephone, over the Internet, or by submitting a properly executed proxy card by mail. The inspector of election will treat abstentions as present for purposes of determining the presence of a quorum.

Q:	Who can vote at the Special Meeting?

Holders of record at the close of business as of the Record Date of Layne Common Stock will be entitled to notice of and to vote at the Special Meeting. Each of the shares of Layne Common Stock issued and outstanding on the Record Date is entitled to one vote at the Special Meeting with regard to each of the proposals described above.

As of May 11, 2018, the Record Date for determining stockholders of Layne entitled to vote at the Special Meeting, there were 20,059,489 shares of Layne Common Stock outstanding and entitled to vote at the Special Meeting, held by approximately 160 holders of record.

Q:	How many votes do I have if I am a Layne stockholder?

A:	Each share of Layne Common Stock that you own at the close of business on the Record Date will entitle you to one vote on each proposal presented at the Special Meeting.

Q:	How many votes are required to approve each proposal, and what happens if I abstain?

Proposal 1—Adoption of the Merger Agreement. Adoption of the Merger Agreement requires the affirmative vote of the holders of a majority of the shares of Layne Common Stock outstanding on the Record Date. Abstentions and failures to vote will have the same effect as a vote against the adoption of the Merger Agreement.

Proposal 2—Approval, on an Advisory Basis, of Certain Compensatory Arrangements with Layne Named Executive Officers. Approval of the compensation proposal requires the approval of a majority of the votes cast “FOR” or “AGAINST” by the Layne stockholders present in person or represented by proxy at the Special Meeting and entitled to vote thereon. Abstentions and failures to vote will have no effect on the compensation proposal.

Proposal 3—Adjournments of the Special Meeting. Approval of the adjournment proposal requires the approval of a majority of the votes cast “FOR” or “AGAINST” by the Layne stockholders present in person or represented by proxy at the Special Meeting and entitled to vote thereon. Abstentions and failures to vote will have no effect on the adjournment proposal.

The Layne Board unanimously recommends that Layne stockholders vote “FOR” the proposal to adopt the Merger Agreement, “FOR” the compensation proposal and “FOR” the adjournment proposal.

In connection with the execution of the Merger Agreement, certain of Layne’s stockholders (including all of Layne’s directors and named executive officers) entered into voting agreements with Granite, pursuant to which they agreed to vote, and granted Granite an irrevocable proxy to vote, their shares of Layne Common Stock in favor of the proposals to be considered at the Special Meeting, including the proposal to adopt the Merger Agreement. As of the Record Date, these stockholders collectively beneficially owned approximately 10.0% of the outstanding shares of Layne Common Stock entitled to vote at the Special Meeting. If the Merger Agreement is terminated in accordance with its terms, these voting agreements will also terminate. A form of the voting agreements is attached hereto as Annex B. See “The Voting Agreements” beginning on page 129 of this proxy statement/prospectus.

Q:	What will happen if all of the proposals to be considered at the Special Meeting are not approved?

A:	As a condition to completion of the Merger, Layne stockholders must adopt the Merger Agreement at the Special Meeting. Completion of the Merger is not conditioned or dependent upon the approval of the compensation proposal or the adjournment proposal.

Q:	Why am I being asked to consider and vote upon a proposal to approve, on a non-binding, advisory basis, the compensation that may be paid or become payable to Layne’s named executive officers that is based on or otherwise relates to the Merger?

A:	Under SEC rules, Layne is required to seek a non-binding, advisory vote with respect to the compensation that may be paid or become payable to Layne’s named executive officers that is based on or otherwise relates to the Merger.

Q:	What happens if the compensation proposal is not approved?

Approval of the compensation proposal is not a condition to the completion of the Merger. The vote is a non-binding, advisory vote. If the Merger is completed, Layne will be obligated to pay all or a portion of this compensation to its named executive officers in connection with the Merger or certain terminations or cessations of employment following the Merger, even if Layne stockholders fail to approve the compensation proposal.

Q:	If I own Layne RSUs or Layne PSUs as of the Record Date issued pursuant to the Layne Equity Plan, will I be able to vote on the matters to be voted upon at the Special Meeting?

A:	No. Layne RSUs and Layne PSUs do not carry any rights to vote at a meeting of Layne stockholders.

Q:	If I am a Layne stockholder and my shares of Layne Common Stock are held in “street name” by a broker, bank or other nominee, how do I vote my shares?

If your shares are held in an account at a brokerage firm, bank or other nominee, then you are the beneficial owner of shares held in “street name” and this proxy statement/prospectus is being sent to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account by following the instructions that the broker, bank or other nominee provides you along with this proxy statement/prospectus. Your nominee or intermediary will vote your shares only if you provide instructions on how to vote by properly completing the voting instruction form sent to you by your nominee or intermediary with this proxy statement/prospectus.

Q:	Who can attend the Special Meeting?

Stockholders of record, or their duly authorized proxies, may attend the Special Meeting. To gain admittance, you must present valid picture identification, such as a driver’s license or passport. If you hold shares in “street name” (through a broker, bank or other nominee) and wish to attend the Special Meeting, you will also need to bring a copy of a brokerage statement (in a name matching your photo identification) reflecting your stock ownership as of the Record Date. If you are a representative of a corporate or institutional stockholder, you must present valid photo identification along with proof that you are a representative of such stockholder.

Please note that use of cameras, recording devices and other electronic devices will not be permitted at the Special Meeting.

Regardless of whether you intend to attend the Special Meeting, you are encouraged to vote your shares of Layne Common Stock as promptly as possible. Voting your shares will not impact your ability to attend the Special Meeting.

Q:	How do I vote my shares?

A:	If you are a Layne stockholder of record, you may vote by mail, by telephone, over the Internet or in person at the Special Meeting. Votes submitted by mail, by telephone or over the Internet must be received by 11:59 p.m., Eastern Time, on June 12, 2018.

Voting by Telephone or over the Internet. To vote by telephone or over the Internet, please follow the instructions included on your proxy card. If you vote by telephone or over the Internet, you do not need to complete and mail a proxy card.

Voting by Mail. By signing the proxy card and returning it in the enclosed prepaid and addressed envelope, you are authorizing the individuals named on the proxy card to vote your shares at the Special Meeting in the manner you indicate. If you receive more than one proxy card, it is an indication that your shares are held in multiple accounts. Please sign and return all proxy cards to ensure that all of your shares are voted.

We encourage you to vote by telephone, over the Internet or to sign and return the proxy card even if you plan to attend the Special Meeting so that your shares will be voted if you are unable to attend the Special Meeting.

Voting in Person at the Meeting. If your shares are registered directly in your name, you are considered the stockholder of record and you have the right to vote in person at the Special Meeting. If you attend the Special Meeting and plan to vote in person, we will provide you with a ballot at the Special Meeting.

- 4 -

Q:	Can I change my vote after I have delivered my proxy?

A:	Yes. You can change your vote at any time before your proxy is voted at the Special Meeting.

If you are a Layne stockholder of record, you may revoke your proxy at any time before it is voted at the Special Meeting. To revoke your proxy, you must:

•

enter a new vote by telephone or over the Internet by 11:59 p.m., Eastern Time, on June 12, 2018;

•

sign and return another proxy card, which must be received by 11:59 p.m., Eastern Time, on June 12, 2018;

•

provide written notice of the revocation to Layne’s Secretary at: Layne Christensen Company, Attention: Senior Vice President, Chief Administrative Officer and General Counsel, 1800 Hughes Landing Blvd., Ste. 800, The Woodlands, Texas 77380, which must be received by 11:59 p.m., Eastern Time, on June 12, 2018; or

•

attend the Special Meeting and vote in person.

If you are the beneficial owner of shares held in “street name” by a brokerage firm, bank or other nominee, you should follow the instructions of your bank, broker or other nominee regarding the revocation of proxies.

Q:	What if I receive more than one proxy card?

A:	If you receive more than one proxy card, your shares of Layne Common Stock are registered in more than one name or are registered in different accounts. Please complete, date, sign and return each appropriate proxy card to ensure that all your shares are voted.

Q:	How will Layne’s outstanding convertible notes be treated in the Merger?

Layne currently has outstanding 4.25% Convertible Notes and 8.0% Convertible Notes. Both the 4.25% Convertible Notes and the 8.0% Convertible Notes will remain outstanding following completion of the Merger. However, following completion of the Merger, the 8.0% Convertible Notes will no longer be convertible into shares of Layne Common Stock but instead will become convertible into a number of shares of Granite Common Stock based on the Exchange Ratio. Under the indenture that governs the 4.25% Convertible Notes, Layne has the option to settle the conversion of any 4.25% Convertible Notes in cash, shares of Layne Common Stock or a combination of both. Pursuant to the Merger Agreement, Layne has agreed to settle the 4.25% Convertible Notes only in cash. The amount of cash to be paid upon conversion of each $1,000 principal amount of 4.25% Convertible Notes will equal the value, as of the conversion date, of a number of shares of Granite Common Stock equal to (a) the current conversion rate of the 4.25% Convertible Notes, which is 43.6072, multiplied by (b) the Exchange Ratio. Assuming the value of one share of Granite Common Stock on the date of conversion is equal to $57.29, the closing price of shares of Granite Common Stock on NYSE on the last practicable trading day before the date of this proxy statement/prospectus, then each $1,000 of 4.25% Convertible Notes would be convertible into $674.50.

Q:	Are Granite stockholders voting on the Merger?

A:	No. No vote of Granite stockholders is required to complete the Merger.

Q:	Should I send in my stock certificates (or evidence of shares in book-entry form) with my proxy card?

A:	No. Please do NOT send your Layne stock certificates (or evidence of shares in book-entry form) with your proxy card. After the Merger is consummated, you will receive written instructions for exchanging your shares of Layne Common Stock for the Merger Consideration.

- 5 -

Q:	When is the Merger expected to be completed?

Granite and Layne are working toward completing the Merger as expeditiously as possible and currently expect the Merger to be completed promptly following the Special Meeting. However, Granite and Layne cannot be certain when, or if, the conditions to the Merger will be satisfied or waived, or that the Merger will be completed.

As more fully described in this proxy statement/prospectus and in the Merger Agreement, the completion of the Merger depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others, (a) the adoption of the Merger Agreement by the holders of a majority of Layne Common Stock entitled to vote on such matter, (b) the expiration or termination of the applicable waiting period under the HSR Act, (c) the effectiveness of the registration statement (of which this proxy statement/prospectus is a part) relating to the issuance of the shares of Granite Common Stock to be issued in the Merger, (d) the approval for listing by NYSE, subject to notice of issuance, of the shares of Granite Common Stock to be issued in the Merger and (e) the absence of any law or regulation that prohibits the completion of the Merger. Each party’s obligation to complete the Merger is also subject to the material accuracy of the representations and warranties of the other party in the Merger Agreement and the compliance in all material respects with covenants of the other party in the Merger Agreement and (e) the absence of a material adverse effect (as described in “The Merger Agreement—Conditions to the Merger” beginning on page 107 of this proxy statement/prospectus) on the other party. The Merger Agreement does not include a financing condition.

Q:	Are there risks associated with the Merger that I should consider in deciding how to vote?

Yes. There are a number of risks related to the Merger and the other transactions contemplated by the Merger Agreement that are discussed in this proxy statement/prospectus and in the documents incorporated by reference or referred to in this proxy statement/prospectus. Please read with particular care the detailed description of the risks described in “Risk Factors” beginning on page 22 of this proxy statement/prospectus and in Layne’s and Granite’s respective filings with the SEC referred to in “Where You Can Find More Information” beginning on page 145 of this proxy statement/prospectus.

Q:	What are the U.S. federal income tax consequences of the Merger to U.S. holders of Layne Common Stock?

Layne and Granite intend that, for U.S. federal income tax purposes, the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. The obligations of Layne and Granite to complete the Merger are subject to, among other conditions described in this proxy statement/prospectus, the receipt by Layne of the Layne Tax Opinion and by Granite of the Granite Tax Opinion, each to the effect that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. However, neither Layne nor Granite intends to request a ruling from the IRS regarding the U.S. federal income tax consequences of the Merger. Accordingly, no assurance can be given that the IRS will not challenge the conclusion that the Merger qualifies for the Intended Tax Treatment or that a court would not sustain such a challenge.

Assuming the Merger qualifies for the Intended Tax Treatment, U.S. Holders (as defined in “Material U.S. Federal Income Tax Consequences” beginning on page 131 of this proxy statement/prospectus) will not recognize any gain or loss upon the receipt of shares of Granite Common Stock in the Merger, except with respect to cash received in lieu of fractional shares of Granite Common Stock.

Each U.S. holder of Layne Common Stock should read the discussion under “Material U.S. Federal Income Tax Consequences” and should consult its own tax advisor for a full understanding of the tax consequences of the Merger to such stockholder.

The Voting Agreements (see page 129)

In connection with the execution of the Merger Agreement, the Voting Stockholders entered into the Voting Agreements with Granite. Pursuant to the Voting Agreements, the Voting Stockholders agreed to vote, and granted Granite an irrevocable proxy to vote, their shares of Layne Common Stock in favor of the adoption of the Merger Agreement and against, among other things, any alternative acquisition proposal. The Voting Agreements provide that the Voting Stockholders will not sell their shares of Layne Common Stock prior to the consummation of the Merger (or earlier termination of the Merger Agreement).

As of the Record Date, the Voting Stockholders, collectively, beneficially owned approximately 10.0% of the outstanding shares of Layne Common Stock entitled to vote at the Special Meeting. If the Merger Agreement is terminated in accordance with its terms, these Voting Agreements will also terminate.

Merger Consideration and Value (see page 106)

At the Effective Time, each share of Layne Common Stock then issued and outstanding (other than shares (a) held in treasury of Layne or (b) directly or indirectly owned by Granite, Merger Sub or a wholly owned subsidiary of Layne) will be cancelled and converted into 0.27 validly issued, fully paid and non-assessable shares of Granite Common Stock. No fractional shares of Granite Common Stock will be issued in the Merger and Layne’s stockholders will receive cash in lieu of any fractional share. Granite expects that it will issue approximately 5.4 million shares of Granite Common Stock in the Merger, excluding any shares that may subsequently be issued in connection with conversion of Layne’s outstanding 8.0% Convertible Notes.

Based on the closing price of shares of Granite Common Stock on NYSE on the last practicable trading day before the date of this proxy statement/prospectus, the Merger Consideration represented $15.47 in value for each share of Layne Common Stock.

The Layne Board’s Reasons for the Merger (see page 78)

At a meeting duly called and held on February 13, 2018, the Layne Board unanimously determined that the Merger Agreement and the Merger were in the best interests of Layne and its stockholders. The Layne Board unanimously recommends that Layne stockholders vote “FOR” the proposal to adopt the Merger Agreement, “FOR” the compensation proposal and “FOR” the adjournment proposal. In the course of reaching its decision to approve the Merger Agreement, the Layne Board considered a number of factors in its deliberations. Those factors are described in “The Merger—Layne Board Recommendation and its Reasons for the Merger” beginning on page 78 of this proxy statement/prospectus.

Opinion of Financial Advisor to Layne (see page 81)

On February 13, 2018, at a meeting of the Layne Board held to evaluate the Merger, Greentech delivered to the Layne Board an oral opinion, which was confirmed by delivery of a written opinion dated February 13, 2018, to the effect that, as of the date of the opinion and subject to the various assumptions made, procedures followed, factors considered, and limitations of the review undertaken, qualifications contained and other matters set forth therein, the Exchange Ratio of 0.27 was fair, from a financial point of view, to the holders of Layne Common Stock (excluding shares owned by Layne as treasury stock, or shares that are owned directly or indirectly by Granite, Merger Sub or any wholly-owned subsidiary of Layne, Granite or Merger Sub).

- 10 -

Annex C and is incorporated by reference herein in its entirety. The following summary of Greentech’s opinion is qualified in its entirety by reference to the full text of the opinion. Greentech delivered its opinion to the Layne Board for the benefit and use of the Layne Board (in its capacity as such) in connection with and for purposes of its evaluation of the Merger. Greentech’s opinion does not address any other aspect of the Merger other than the fairness of the Exchange Ratio, from a financial point of view, to the holders of Layne Common Stock (excluding shares owned by Layne as treasury stock, or shares that are owned directly or indirectly by Granite, Merger Sub or any wholly-owned subsidiary of Layne, Granite or Merger Sub), and no opinion or view was expressed as to the relative merits of the Merger in comparison to other strategies or transactions that might be available to Layne or in which Layne might engage or as to the underlying business decision of Layne to proceed with or effect the Merger. Greentech’s opinion does not constitute a recommendation to the Layne Board as to how the Layne Board should vote on the Merger or to any stockholder of Layne as to how any such stockholder should vote at any stockholders’ meeting at which the Merger is considered, or whether or not any stockholder of Layne should enter into a voting, shareholders’, or affiliates’ agreement with respect to the Merger or exercise any dissenter’s or appraisal rights that may be applicable to such stockholder.

Treatment of Layne Stock Options, Layne RSUs and Layne PSUs (see page 77)

Layne Stock Options

Each Layne Stock Option that is outstanding immediately prior to the Effective Time (whether vested or unvested) shall, immediately prior to the Effective Time, automatically and without any action on the part of any holder of any Layne Stock Option be cancelled and, in exchange therefor, converted into the right to receive an amount of cash, if any, equal to the product of (a) the number of shares of Layne Common Stock issuable upon the exercise of the Layne Stock Option, multiplied by (b) the excess, if any, of (1) the Layne Equity Award Consideration, over (2) the exercise price of the Layne Stock Option. Such cash amount, net of applicable withholding tax, will be paid to the holder as soon as practicable following the Effective Time.

Layne RSUs

Each Layne RSU that is outstanding immediately prior to the Effective Time (whether vested or unvested) shall automatically and without any action on the part of any holder of any Layne RSU, be cancelled and, in exchange therefor, converted into the right to receive an amount of cash (without interest) equal to the product of (a) the number of shares of Layne Common Stock in respect of the Layne RSU, multiplied by (b) the Layne Equity Award Consideration. Such cash amount, net of applicable withholding tax, will be paid to the holder at the earliest time permitted under the terms of the award such that it does not result in tax penalties.

Layne PSUs

Each Layne PSU that is outstanding and unvested immediately prior to the Effective Time shall, immediately prior to the Effective Time, vest, and the underlying number of shares of Layne Common Stock earned be determined based on the maximum level of achievement of the applicable performance goals.

All Layne PSUs that are vested immediately prior to the Effective Time (including the Layne PSUs that vest pursuant to the terms of the Merger Agreement) shall automatically and without any action on the part of any holder of any Layne PSU, be cancelled and, in exchange therefor, converted into the right to receive an amount of cash (without interest) equal to the product of (a) the number of shares of Layne Common Stock earned in respect of the Layne PSU, multiplied by (b) the Layne Equity Award Consideration. Such cash amount, net of applicable withholding tax, will be paid to the holder as soon as practicable following the Effective Time, such that it does not result in tax penalties.

- 11 -

Interests of Layne Directors and Executive Officers in the Merger (see page 95)

You should be aware that the directors and executive officers of Layne will have interests in the Merger that may be different from or in addition to those of Layne’s stockholders generally. These interests include, but are not limited to, the treatment in the Merger of Layne’s equity compensation awards (including the acceleration of Layne Stock Options, Layne RSUs and Layne PSUs), severance agreements and other rights that may be held by Layne’s directors and executive officers, and the indemnification of current and former Layne directors and officers by the Surviving Corporation. The Layne Board was aware of and considered these interests, among other matters, in reaching its decision to approve the Merger Agreement and recommend that Layne’s stockholders adopt the Merger Agreement.

Conditions to the Merger (see page 107)

Granite and Layne currently expect to complete the Merger promptly following the Special Meeting, subject to receipt of required stockholder and regulatory approvals and the satisfaction or waiver of the other conditions to the Merger. As more fully described in this proxy statement/prospectus and in the Merger Agreement, each party’s obligation to complete the Merger depends on a number of conditions being satisfied or waived, including the following:

Granite Board Following the Merger (see page 125)

Pursuant to the Merger Agreement, Granite will expand the size of the Granite Board and designate one non-employee director of Layne who is a director prior to the Effective Time to fill such vacancy. That designee will serve until Granite’s 2019 annual meeting of stockholders or such person’s earlier death, retirement, resignation or removal by Granite’s stockholders.

Regulatory Approvals Required to Complete the Merger (see page 102)

Granite and Layne have agreed to cooperate and use reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the Merger Agreement. For an acquisition transaction meeting certain size thresholds, such as the Merger, the HSR Act requires the parties to file notification and report forms with the Antitrust Division of the DOJ and the FTC and to observe specified waiting period requirements before completing the Merger. Granite and Layne filed the required notifications with the Antitrust Division of the DOJ and the FTC. On March 12, 2018, the FTC granted early termination of the waiting period under the HSR Act.

Termination of the Merger Agreement (see page 115)

Granite and Layne may terminate the Merger Agreement at any time before the Effective Time under the following circumstances:

•

by mutual written consent of Granite and Layne at any time prior to the Effective Time whether before or after Layne’s stockholders have adopted the Merger Agreement;

•

if the Merger is not consummated on or before September 30, 2018; provided, however, that this right to terminate the Merger Agreement will not be available to any party whose failure to fulfill any obligation under the Merger Agreement caused the failure of the Effective Time to occur on or before September 30, 2018;

•

if any governmental authority shall have (a) enacted, issued, promulgated or enforced any law that makes consummation of the Merger illegal or otherwise prohibited or (b) enacted, issued, promulgated, enforced or entered any order which has the effect of making the consummation of the Merger illegal or otherwise preventing or prohibiting consummation of the Merger; or

•

if the Special Meeting (including any adjournment or postponement thereof) has concluded, Layne’s stockholders have voted and approval was not obtained; provided, however, that the right to terminate

the Merger Agreement shall not be available to Layne if it has not materially complied with certain of the covenants relating to the conduct of its business and the proxy statement and the holding of the Special Meeting.

In addition, Layne may terminate the Merger Agreement at any time prior to the Effective Time under the following circumstances:

•

if there should have occurred any effects, events, occurrences, developments, state of facts or changes that, individually or in the aggregate, have had or would reasonably be expected to have, individually or in the aggregate, a Granite material adverse effect (as described in “The Merger Agreement—Conditions to the Merger” beginning on page 107 of this proxy statement/prospectus), or Granite has breached any representation, warranty, covenant or agreement contained in the Merger Agreement, or if any representation or warranty of Granite has become untrue, in each case, such that the conditions to closing relating to the accuracy of Granite’s representations and warranties or the performance by Granite of its obligations under the Merger Agreement could not be satisfied as of the earlier of September 30, 2018 or the date that is 30 days following written notice thereof; provided, however, Layne may not terminate the Merger Agreement if Layne is then in material breach of any representation, warranty or covenant of Layne; or

•

prior to adoption of the Merger Agreement by Layne’s stockholders, in order to enter into a definitive written agreement providing for a superior proposal in compliance with the non-solicitation provisions of the Merger Agreement.

In addition, Granite may terminate the Merger Agreement at any time prior to the Effective Time under the following circumstances:

•

if there should have occurred any effects, events, occurrences, developments, state of facts or changes that, individually or in the aggregate, have had or would reasonably be expected to have, individually or in the aggregate, a Layne material adverse effect (as described in “The Merger Agreement—Conditions to the Merger” beginning on page 107 of this proxy statement/prospectus), or Layne has breached any representation, warranty, covenant or agreement contained in the Merger Agreement, or if any representation or warranty of Layne has become untrue, in each case, such that the conditions to closing relating to the accuracy of Layne’s representations and warranties or the performance by Layne of its obligations under the Merger Agreement could not be satisfied as of the earlier of September 30, 2018 or the date that is 30 days following written notice thereof; provided, however, neither Granite nor Merger Sub may terminate the Merger Agreement if Granite or Merger Sub is then in material breach of any representation, warranty or covenant of Granite or Merger Sub, as applicable;

•

if Layne (a) withdraws, modifies or qualifies in a manner adverse to Granite or Merger Sub the Layne Board’s recommendation of the Merger or the approval or declaration of advisability by the Layne Board of the Merger Agreement and the transactions contemplated thereby (including the Merger) or (b) approve or recommend, or resolve to or publicly propose to approve or recommend, any acquisition proposal;

•

the Layne Board or any committee thereof (a) has not rejected any acquisition proposal within seven days of the making thereof (including, for these purposes, by taking no position with respect to the acceptance by Layne’s stockholders of a tender offer or exchange offer, which shall constitute a failure to reject such acquisition proposal) or (b) has failed, pursuant to Rule 14e-2 promulgated under the Exchange Act or otherwise, to publicly reconfirm the Layne Board’s recommendation of the Merger within four days after receipt of a written request from Granite that it do so if such request is made following the making by any person of an acquisition proposal; or

•

Layne has violated or breached in any material respect any of its obligations in the no solicitation provisions of the Merger Agreement described under “ —No Solicitation of Acquisition Proposals.”

- 14 -

In some cases, termination of the Merger Agreement may require Layne to pay a termination fee to Granite as described below.

No Solicitation of Acquisition Proposals (see page 110)

The Merger Agreement contains detailed provisions prohibiting Layne from seeking an alternative transaction to the Merger. Under these “no solicitation” provisions, Layne has agreed that, from the time of the execution and delivery of the Merger Agreement until the earlier of the Effective Time or the termination of the Merger Agreement in accordance with its terms, Layne will not, and will cause its subsidiaries and its directors, officers, employees, financial advisors, attorneys, accountants or other advisors, agents or representatives to not:

•

solicit, initiate, cause or knowingly facilitate or encourage (including by way of furnishing information) the submission of any inquiries, proposals or offers or any other efforts or attempts that constitute or may reasonably be expected to lead to any “acquisition proposal” (as described under “The Merger Agreement—No Solicitation of Acquisition Proposals” beginning on page 110 of this proxy statement/prospectus);

•

engage in any discussions or negotiations or otherwise cooperate with or assist or participate in, or knowingly facilitate or encourage, any inquiries, proposals, discussions or negotiations of any acquisition proposal or resolve to or publicly propose to take any of the above actions;

•

approve or recommend, or resolve to or publicly propose to approve or recommend, any acquisition proposal;

•

enter into any Merger Agreement, agreement-in-principle, letter of intent, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other similar agreement relating to an acquisition proposal or enter into any letter of intent, agreement or agreement-in-principle requiring Layne (whether or not subject to conditions) to abandon, terminate or fail to consummate the Merger;

•

withdraw, modify or qualify in a manner adverse to Granite or Merger Sub the Layne Board’s recommendation regarding the Merger Agreement, or the approval or declaration of advisability by the Layne Board of the Merger Agreement, as well as the Merger and the other transactions contemplated in connection with the Merger; or

•

approve or recommend, or resolve to or publicly propose to approve or recommend, any acquisition proposal.

Notwithstanding these restrictions, the Merger Agreement also provides that if, at any time after execution of the Merger Agreement, Layne receives a bona fide acquisition proposal which did not result from a breach of the non-solicitation provisions of the Merger Agreement, Layne is permitted to contact the person or group of persons who made the acquisition proposal to clarify terms for the sole purpose of the Layne Board informing itself about such acquisition proposal. In the event that the Layne Board determines in good faith, after consultation with its financial advisor(s) and outside legal counsel, that such acquisition proposal constitutes or is reasonably likely to lead to a “superior proposal” (as described under “The Merger Agreement—No Solicitation of Acquisition Proposals” beginning on page 110 of this proxy statement/prospectus) and that failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable law, then Layne is also permitted to:

•

furnish confidential information with respect to Layne and its subsidiaries to the person making such acquisition proposal; and

•

participate in discussions or negotiations with the person making such acquisition proposal regarding such acquisition proposal.

- 15 -

Layne has also agreed in the Merger Agreement that it will promptly (and in any event within 24 hours) notify Granite, orally and in writing, if Layne, its subsidiaries or any of their respective representatives receives any (a) acquisition proposal or indication by any person that it is considering making an acquisition proposal, (b) request for non-public information in contemplation of an acquisition proposal, or (c) inquiry or request for discussions or negotiations regarding any acquisition proposal. Such notice must include the identity of the person making the proposal, offer, request or inquiry and the other material terms and conditions of any such proposal or offer and copies of all relevant documents relating thereto. In addition, Layne has agreed to keep Granite reasonably informed on a current basis (and in any event no later than 24 hours after the occurrence of any material changes, developments, discussions or negotiations) as to the status of any acquisition proposal, indication, inquiry or request (including the material terms and conditions thereof and of any material modification thereto), and any developments, discussions and negotiations, including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any oral inquiries or discussions.

In addition, the Layne Board may, at any time after the date of the Merger Agreement and prior to the adoption of the Merger Agreement by Layne’s stockholders, in response to a superior proposal that did not result from a breach of the non-solicitation provisions of the Merger Agreement, effect an adverse recommendation change (as described in “The Merger Agreement—Conditions to the Merger” beginning on page 107 of this proxy statement/prospectus) and/or terminate the Merger Agreement to accept the superior proposal (after paying the termination fee as described below) if the Layne Board determines in good faith, after consultation with its financial advisor(s) and outside legal counsel, that failing to take any such action would be inconsistent with the directors’ fiduciary duties under applicable law, and if certain other conditions which are described elsewhere in the Merger Agreement and in this proxy statement/prospectus are satisfied. In such an event, Layne may be required to pay Granite a termination fee of $16.0 million.

Further, the Layne Board may, at any time after the date of the Merger Agreement and prior to the adoption of the Merger Agreement by Layne’s stockholders, in response to an intervening event (as described in “The Merger Agreement—No Solicitation of Alternative Proposals” beginning on page 110 of this proxy statement/prospectus) that did not result from a breach of the non-solicitation provisions of the Merger Agreement, effect an adverse recommendation if the Layne Board determines in good faith, after consultation with outside counsel, that in light of the existence of such intervening event, the failure to make an adverse recommendation change would be inconsistent with the directors’ fiduciary duties under applicable law.

Expenses, Termination Fee Relating to the Merger (see page 117)

Generally, all fees and expenses incurred in connection with the Merger Agreement will be paid by the party incurring those fees and expenses. Following termination of the Merger Agreement under specified circumstances, Layne may be required to pay Granite a termination fee of $16.0 million.

Accounting Treatment of the Merger (see page 104)

Granite prepares its financial statements in accordance with GAAP. The Merger will be accounted for by Granite as a business combination under the acquisition method of accounting, and Granite will be treated as the acquirer for accounting purposes.

Material U.S. Federal Income Tax Consequences (see page 131)

- 16 -

receipt by Layne of the Layne Tax Opinion and by Granite of the Granite Tax Opinion, each to the effect that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. However, neither Layne nor Granite intends to request a ruling from the IRS regarding the U.S. federal income tax consequences of the Merger. Accordingly, no assurance can be given that the IRS will not challenge that conclusion that the Merger qualifies for the Intended Tax Treatment or that a court would not sustain such a challenge.

Comparison of the Rights of Holders of Granite Common Stock and Layne Common Stock (see page 134)

As a result of the completion of the Merger, holders of Layne Common Stock will become holders of Granite Common Stock. Each of Granite and Layne is a Delaware corporation governed by the DGCL, but the rights of Granite stockholders currently are, and from and after the Merger will be, governed by the Granite Charter and the Granite Bylaws, while the rights of Layne stockholders are currently governed by the Layne Charter and the Layne Bylaws. This proxy statement/prospectus includes summaries of the material differences between the rights of Granite stockholders and Layne stockholders arising because of difference in the charters and bylaws of the two companies.

No Appraisal Rights in Connection with the Merger (see page 103)

Section 262 of the DGCL provides that stockholders have the right, in some circumstances, to dissent from certain corporate actions and to instead demand payment of the fair value of their shares. Stockholders do not have appraisal rights with respect to shares of any class or series of stock if such shares of stock, or depositary receipts in respect thereof, are either (a) listed on a national securities exchange or (b) held of record by more than 2,000 holders, unless the stockholders receive in exchange for their shares anything other than shares of stock of the surviving or resulting corporation (or depositary receipts in respect thereof), or of any other corporation that is publicly listed or held by more than 2,000 holders of record, cash in lieu of fractional shares or fractional depositary receipts described above or any combination of the foregoing. Therefore, because shares of Layne Common Stock are listed on Nasdaq, and the Merger Consideration consists of only shares of Granite Common Stock, which will be publicly listed on NYSE, and cash in lieu of fractional shares, holders of Layne Common Stock are not entitled to appraisal rights in the Merger with respect to their shares of Layne Common Stock.

Special Meeting (see page 51)

The Special Meeting will be held at 9:00 a.m. (Central Time), on June 13, 2018 located at 1800 Hughes Landing Boulevard, Ste. 700, The Woodlands, TX 77380.

Holders of record of Layne Common Stock at the close of business on the Record Date will be entitled to notice of and to vote at the Special Meeting with regard to the proposals to be considered at that meeting. On the Record Date, there were 20,059,489 shares of Layne Common Stock outstanding and entitled to vote at the Special Meeting, held by approximately 160 holders of record. Each share of Layne Common Stock issued and outstanding on the Record Date is entitled to one vote on each proposal to be voted upon at the Special Meeting.

- 17 -

As of the Record Date, Layne’s directors and Executives, and their affiliates, as a group, owned and were entitled to vote 1,997,308 shares of Layne Common Stock, or approximately 10.0% of the outstanding shares of Layne Common Stock. As of the Record Date, Wynnefield Capital Management, LLC and certain of its affiliates, as a group, owned and were entitled to vote 1,798,245 shares of Layne Common Stock, or approximately 9.0% of the outstanding shares of Layne Common Stock. To be approved, the proposal to adopt the Merger Agreement requires the affirmative vote of the holders a majority of the shares of Layne Common Stock outstanding on the Record Date, and each of the compensation proposal and adjournment proposal requires the affirmative vote of a majority of the votes cast “FOR” or “AGAINST” by the Layne stockholders present in person or represented by proxy at the Special Meeting. In connection with the Merger, the Voting Stockholders have entered into Voting Agreements with Granite. The Voting Agreements provide, among other things, that the Voting Stockholders will not sell their shares of Layne Common Stock prior to the consummation of the Merger (or earlier termination of the Merger Agreement). See “The Voting Agreements” beginning on page 129 of this proxy statement/prospectus.

Litigation Relating to the Merger (see page 104)

On April 3, 2018, two putative class actions, captioned Malka Raul v. Layne Christensen Company, et al., and Colleen Witmer v. Layne Christensen Company, et al., were filed in the U.S. District Court for the Southern District of Texas against Layne, Layne’s directors, Granite and Merger Sub. The complaints generally allege that Layne, the Layne directors and Granite disseminated a false or misleading registration statement regarding the proposed merger in violation of Section 14(a) of the Exchange Act and SEC Rule 14a-9. Specifically, the complaints allege that the registration statement misstated or omitted material information regarding the parties’ financial projections, the valuation analysis performed by Greentech in support of its fairness opinion, and potential conflicts of interest of Greentech. The complaints further allege that the Layne directors and/or Granite are liable for these violations as “controlling persons” of Layne under Section 20(a) of the Exchange Act. The complaints seek injunctive relief, including to enjoin and/or rescind the merger, rescission or rescissory damages in the event the merger is consummated, and an award of attorneys’ fees, in addition to other relief.

Comparative Market Value of Common Stock

Granite Common Stock are traded on NYSE under the symbol “GVA” and shares of Layne Common Stock are traded on Nasdaq under the symbol “LAYN.” The following table shows the closing prices per share of Granite Common Stock and Layne Common Stock as reported on February 13, 2018, the final trading day prior to the public announcement of the Merger, and on May 14, 2018, the latest practicable date prior to the date of this proxy statement/prospectus. This table also shows the implied value of the Merger Consideration for each share of Layne Common Stock, which was calculated by multiplying the closing price of Granite Common Stock on the relevant date by the Exchange Ratio for each share of Layne Common Stock.


	Closing Price of Granite Common Stock		Closing Price of Layne Common Stock		Implied Value of Merger Consideration
As of February 13, 2018	$	60.08	$	12.62	$	16.22
As of May 14, 2018	$	57.29	$	15.26	$	15.47

The market price of Granite Common Stock and Layne Common Stock will fluctuate prior to the Special Meeting and before the Merger is consummated, which will affect the implied value of the Merger Consideration paid to Layne stockholders.

- 21 -

RISK FACTORS

In addition to the other information included in and incorporated by reference into this proxy statement/prospectus, you should carefully read and consider the following risk factors in evaluating the proposals to be voted on at the Special Meeting and in determining whether to vote for adoption of the Merger Agreement. If the Merger Agreement is adopted by Layne stockholders and all of the other conditions to the Merger are satisfied or waived, and the Merger is consummated, holders of Layne Common Stock will become holders of Granite Common Stock and will be subject to the risks and uncertainties of holders thereof. Please also refer to the additional risk factors of each of Granite and Layne identified in the periodic reports and other documents incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 145 of this proxy statement/prospectus.

Risks Related to the Merger

Because the market price of Granite Common Stock will fluctuate, Layne’s stockholders cannot be certain of the value of the Merger Consideration that they will be entitled to receive in the Merger.

Upon consummation of the Merger, each share of Layne Common Stock then issued and outstanding will be cancelled and automatically converted into the right to receive 0.27 shares of Granite Common Stock. Granite will not issue any fractional shares of Granite Common Stock in the Merger. Holders of Layne Common Stock who would otherwise be entitled to a fractional share of Granite Common Stock will receive a cash payment in lieu of any fractional share. See “Unaudited Comparative Per Share Data” and “Comparative Market Value of Common Stock and Dividend Information” beginning on pages 48 and 49, respectively.

The Merger Agreement does not provide for any termination right by either Granite or Layne solely based on changes in the price or trading volume of Granite Common Stock or Layne Common Stock. Fluctuations in the market price of Granite Common Stock could result from changes in the business, operations or prospects of Layne or Granite prior to consummation of the Merger or the combined company following the completion of the Merger, regulatory considerations, general market and economic conditions and other factors both within and beyond the control of Layne or Granite.

The issuance of Granite Common Stock in connection with the Merger could decrease the market price of Granite Common Stock.

Upon consummation of the Merger, Granite expects to issue approximately 5.4 million shares of Granite Common Stock, or approximately 12% of the number of shares of Granite Common Stock outstanding as of February 13, 2018, the last trading day prior to the public announcement of the Merger Agreement, to Layne stockholders in the Merger. This does not include any shares of Granite Common Stock that may become issuable upon conversion of the 8.0% Convertible Notes. The issuance of Granite Common Stock in the Merger may result in fluctuations in the market price of Granite Common Stock, including a stock price decline.

The shares of Granite Common Stock to be received by Layne stockholders as a result of the Merger will have different rights from the shares of Layne Common Stock.

Upon consummation of the Merger, Layne stockholders will become Granite stockholders, and their rights as stockholders will be governed by the Granite Charter and the Granite Bylaws. Certain of the rights associated with Granite Common Stock are different from, and may be viewed as less favorable than, the rights associated with Layne Common Stock. See “Comparison of Rights of Holders of Granite Common Stock and Layne Common Stock” beginning on page 134 of this proxy statement/prospectus for a discussion of the different rights associated with Granite Common Stock.

- 22 -

Granite and Layne may be unable to satisfy the conditions to the Merger and the Merger may not be consummated.

Consummation of the Merger is subject to various closing conditions, including, among other things, (a) the adoption of the Merger Agreement by Layne’s stockholders, (b) the expiration or termination of the applicable waiting period under the HSR Act, (c) the receipt of an opinion of counsel by both Granite and Layne, dated as of the closing, to the effect that the Merger will qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Code and (d) the absence of any legal restraints or prohibitions on the consummation of the Merger. The obligation of each party to consummate the Merger is also conditioned upon the other party’s representations and warranties being true and correct (subject to certain materiality exceptions), the other party having performed in all material respects its obligations under the Merger Agreement and the other party not having suffered a material adverse effect (as described in “The Merger Agreement—Conditions to the Merger” beginning on page 107 of this proxy statement/prospectus).

These and other conditions to consummation of the Merger may fail to be satisfied. In addition, satisfying the conditions to the Merger may take longer, and could cost more, than Layne and Granite expect. For a more complete summary of the conditions that must be satisfied or waived prior to consummation of the Merger, see “The Merger Agreement—Conditions to the Merger” beginning on page 107 of this proxy statement/prospectus. The satisfaction of all of the required conditions could delay the completion of the Merger for a significant period of time or prevent it from occurring. Any delay in completing the Merger could cause Granite not to realize some or all of the benefits that Granite expects to achieve if the Merger is successfully consummated within its expected timeframe. Further, there can be no assurance that the conditions to the Merger will be satisfied or waived or that the Merger will be consummated. See “—Failure to complete the Merger could negatively impact the stock price and the future business and financial results of Granite and Layne.”

Layne must obtain approval of its stockholders to consummate the Merger, which, if delayed or not obtained, may jeopardize or delay the consummation of the Merger.

The Merger is conditioned on the adoption of the Merger Agreement by the affirmative vote of the holders of a majority of the issued and outstanding shares of Layne Common Stock entitled to vote thereon. If Layne stockholders do not adopt the Merger Agreement, then Layne and Granite cannot consummate the Merger.

Regulatory approvals that are required to consummate the Merger may not be received, may take longer than expected or may impose conditions that are not presently anticipated.

Under the provisions of the HSR Act, the Merger may not be consummated until notification and report forms have been filed with the Antitrust Division of the DOJ and the FTC and the expiration of a 30 calendar day waiting period (unless the waiting period is set to expire on a weekend or federal holiday, in which case the waiting period is automatically extended until 11:59 p.m. of the next business day), or the early termination of that waiting period, following the parties’ filing of their respective notification and report forms. On February 28, 2018, Layne and Granite filed their respective notification and report forms under the HSR Act with the Antitrust Division of the DOJ and the FTC. Although the FTC granted early termination of the waiting period under the HSR Act on March 12, 2018, parties who may be adversely affected by the Merger may bring legal actions under the antitrust laws in certain circumstances.

In addition, private parties who may be adversely affected by the Merger and individual states may bring legal actions under the antitrust laws in certain circumstances. Although the parties believe the completion of the Merger will not likely be prevented by antitrust law, there can be no assurance that a challenge to the Merger on antitrust grounds will not be made or, if a challenge is made, what the result will be. Under the Merger Agreement, Layne and Granite have agreed to use their reasonable best efforts to obtain all regulatory clearances necessary to complete the Merger as promptly as reasonably practicable. In addition, in order to complete the Merger, Granite and Layne may be required to comply with conditions, terms, obligations or restrictions imposed

by regulatory entities and such conditions, terms, obligations or restrictions may have the effect of delaying completion of the Merger, imposing additional material costs on or materially limiting the revenues of Granite after the completion of the Merger, or otherwise reducing the anticipated benefits to Granite of the Merger. In addition, such conditions, terms, obligations or restrictions may result in the delay or abandonment of the Merger.

The announcement and pendency of the Merger could have an adverse effect on Layne’s stock price, business, financial condition, results of operations or business prospects.

The announcement and pendency of the Merger could disrupt Layne’s business in the following ways, among others:

•

Layne employees may experience uncertainty regarding their future roles with Granite, which might adversely affect Layne’s ability to retain, recruit and motivate key personnel;

•

the attention of Layne’s management may be directed towards consummating the Merger and transaction-related considerations and may be diverted from the day-to-day business operations of Layne, and matters related to the Merger may require commitments of time and resources that could otherwise have been devoted to other opportunities that might have been beneficial to Layne; and

•

customers, suppliers and other third parties with business relationships with Layne may decide not to renew or seek to terminate, change and/or renegotiate their relationships with Layne as a result of the Merger, whether pursuant to the terms of their existing agreements with Layne or otherwise.

Any of these matters could adversely affect the stock price, business, financial condition, results of operations or business prospects of Layne.

Failure to consummate the Merger could negatively impact the stock price and the future business and financial results of Granite and Layne.

If the Merger is not consummated for any reason, including as a result of Layne stockholders failing to adopt the Merger Agreement, the ongoing businesses of Granite and Layne may be adversely affected and, without realizing any of the benefits of having completed the Merger, Granite and Layne would be subject to a number of additional risks and consequences, including the following:

•

Granite and Layne may experience negative reactions from the financial markets, including negative impacts on their respective stock prices;

•

Granite and Layne may experience negative reactions from their respective customers, suppliers, and regulators;

•

uncertainty regarding the completion of the Merger may foster uncertainty among employees about their future roles, which could adversely affect the ability of Granite and Layne to attract and retain key personnel;

•

Granite and Layne will be required to pay certain costs relating to the Merger, whether or not the Merger is consummated;

•

the Merger Agreement places certain restrictions on the conduct of Layne’s and Granite’s businesses prior to completion of the Merger, which may affect the ability of Layne to execute certain business strategies or pursue otherwise attractive business opportunities. Such restrictions, the waiver of which is subject to the consent of the other party (in certain cases, not to be unreasonably withheld, conditioned or delayed), may prevent Layne from making certain acquisitions or taking certain other specified actions during the pendency of the Merger (see “The Merger Agreement—Conduct of Business Pending the Merger” beginning on page 118, of this proxy statement/prospectus for a description of the restrictive covenants applicable to Layne); and

- 24 -

•

matters relating to the Merger (including integration planning) will require substantial commitments of time and resources by Granite and Layne management, which would otherwise have been devoted to day-to-day operations and other opportunities that may have been beneficial to either Granite or Layne as an independent company.

In addition to the above risks, Layne may be required, under certain circumstances, to pay to Granite the termination fee, which may materially adversely affect Layne’s financial results. Further, Granite and Layne could be subject to litigation related to any failure to complete the Merger or related to any enforcement proceeding commenced against Granite or Layne to perform their respective obligations under the Merger Agreement. If the Merger is not completed, these risks may materialize and may adversely affect Granite’s and Layne’s businesses, financial condition, financial results and stock prices.

Granite’s and Layne’s business relationships may be subject to disruption due to uncertainty associated with the Merger.

Parties with which Granite or Layne do business may experience uncertainty associated with the proposed Merger, including with respect to current or future business relationships with Granite, Layne or the combined company. Granite’s and Layne’s business relationships may be subject to disruption as customers, distributors, suppliers, vendors and others may attempt to negotiate changes in existing business relationships or consider entering into business relationships with parties other than Granite, Layne or the combined company. These disruptions could have an adverse effect on the businesses, financial condition, or results of operations of the combined company, including an adverse effect on Granite’s ability to realize the anticipated benefits of the Merger. The risk, and adverse effect, of such disruptions could be exacerbated by a delay in consummating the Merger or termination of the Merger Agreement.

Any delay in consummating the Merger may substantially reduce the benefits that Granite expects to obtain from the Merger.

Satisfying the conditions to, and consummation of, the Merger may take longer than, and could cost more than, Granite and Layne expect. Granite and Layne cannot predict whether or when the conditions to the Merger will be satisfied, and satisfying the conditions to the Merger could delay the Effective Time for a significant period of time or prevent it from occurring. Any delay in consummating the Merger or any additional conditions imposed in order to consummate the Merger may materially adversely affect the synergies and other benefits that Granite expects to achieve if the Merger and the integration of the companies’ respective businesses are completed within the expected timeframe. In addition, each of Granite and Layne may terminate the Merger Agreement if the Merger is not consummated by September 30, 2018.

Granite may be unable to realize anticipated cost synergies or may incur additional costs.

Granite has identified approximately $20 million in pre-tax cost synergies which are expected to be realized by the third year following consummation of the Merger. Granite expects that these will result from, among other things, combining the organizational structures, locations and operations of the two companies. To realize these synergies, Granite expects to incur costs of approximately $7 million in 2018, $1 million in 2019, and $3 million in 2020. While Granite’s management believes that these cost synergies are achievable, Granite may be unable to realize all of these cost synergies within the time frame expected or at all. In addition, Granite may incur additional and/or unexpected costs in order to realize these cost synergies.

The integration of Layne may present significant challenges to Granite, and although Granite expects the Merger with Layne will result in cost savings, synergies and other benefits to Granite, Granite may not realize those benefits because of difficulties related to integration, the realization of synergies, and other challenges.

Granite and Layne have operated and, until consummation of the Merger, will continue to operate, independently, and there can be no assurances that their businesses can be integrated successfully. It is possible

- 25 -

that the integration process could result in the loss of key Granite or Layne employees, the loss of customers, the disruption of either company’s or both companies’ ongoing businesses or other unexpected integration issues, higher than expected integration costs and an overall post-completion integration process that takes longer than originally anticipated. Specifically, the following issues and potential risks, among others, must be addressed in integrating the operations of Layne and Granite in order to realize the anticipated benefits of the Merger so the combined company performs as expected:

•

failure to implement Granite’s business plan for the combined business, including as a result of Granite’s lack of familiarity with certain of Layne’s existing businesses and conducting business in certain countries in which Layne currently operates;

•

combining the businesses of Granite and Layne and meeting the capital requirements of the combined company in a manner that permits Granite to achieve the cost savings or revenue synergies anticipated to result from the Merger, the failure of which would result in the anticipated benefits of the Merger not being realized in the time frame currently anticipated or at all;

•

harmonizing the companies’ operating practices, employee development and compensation programs, internal controls and other policies, procedures and processes;

•

potential deterioration in the financial performance of Layne, including any potential deviation in results of operations from historical levels;

•

difficulties in the assimilation and retention of employees;

•

demands on management related to the increase in the size of Granite after the acquisition;

•

the diversion of management’s attention from the management of daily operations to the integration of operations;

•

unanticipated changes in applicable laws and regulations;

•

difficulties and risks in the integration of departments and systems (including accounting, health information and management information systems), technologies (including software), books and records and procedures, as well as in maintaining uniform standards and controls (including internal control over financial reporting and related procedures and policies);

•

costs, including legal and settlement costs, associated with Layne’s legal proceedings and other loss contingencies (including with respect to current and legacy projects undertaken and liabilities assumed by Layne and businesses that Layne has sold or discontinued), in each case whether known or unknown and whether relating to past, present or future facts, events, circumstances or occurrences, any of which could be materially adverse to the business, results of operations, assets or financial condition of Layne and, following the Merger, the financial position, results of operations and liquidity of Granite and the ability of Granite to achieve expected benefits of the Merger; and

•

other unanticipated issues, expenses, or liabilities that could impact, among other things, Granite’s ability to realize any expected synergies on a timely basis, or at all.

If Granite cannot successfully integrate Layne, Granite may experience material negative consequences to its business, financial condition or results of operations. Successful integration of Layne will depend on Granite’s ability to manage these operations, to realize opportunities for revenue growth and, to some degree, to eliminate redundant and excess costs. Because of difficulties in combining the two companies, Granite may not be able to achieve the benefits that it hopes to achieve as a result of the Merger.

The Merger may be consummated on different terms from those contained in the Merger Agreement.

Prior to the consummation of the Merger, the parties may, by their mutual agreement, amend or alter the terms of the Merger Agreement, including with respect to, among other things, the Merger Consideration to be received by Layne stockholders, or any covenants or agreements with respect to the parties’ respective operations

- 26 -

during the pendency thereof, provided, however, that after approval by Layne stockholders, no amendment may be made without further stockholder approval which, by law or in accordance with the rules of Nasdaq, requires further approval by such stockholders. Any such amendments or alterations may have negative consequences to Layne stockholders including, among other things, reducing the cash available for Granite’s or Layne’s operations or to meet respective obligations or restricting or limiting assets or operations of either of Granite or Layne. Under certain circumstances, Layne stockholders may be permitted or required to adopt any such amendments, which could delay consummation of the Merger and subject Layne and Granite to additional expense.

Granite and Layne will incur significant transaction fees and Merger-related costs in connection with the Merger.

Granite and Layne expect to incur a number of non-recurring fees and Merger-related costs associated with combining the operations of the two companies. Most of these non-recurring costs will be comprised of transaction and regulatory costs related to the Merger, including fees paid to financial and legal advisors related to the Merger, bank fees and related financing costs and employment-related costs, including change-in-control related payments made to certain Layne executives, further described in “Interests of Certain Persons in the Merger” beginning on page 95 of this proxy statement/prospectus.

Granite will also incur transaction fees and costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and employment-related costs. Granite continues to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the Merger and the integration of the two companies’ businesses. Although Granite expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow Granite to offset incremental Merger and integration-related costs over time, this net benefit may not be achieved in the near term, or at all. See “ —The integration of Layne may present significant challenges to Granite, and although Granite expects the Merger with Layne will result in cost savings, synergies and other benefits to Granite, Granite may not realize those benefits because of difficulties related to integration, the realization of synergies, and other challenges.”

As a result of the Merger, Granite’s goodwill, indefinite-lived intangible assets, and other intangible assets in its consolidated balance sheet will increase. If its goodwill, indefinite-lived intangible assets, or other intangible assets become impaired in the future, Granite would be required to record a material, non-cash charge to earnings, which would also reduce its stockholders’ equity.

Under GAAP, goodwill and indefinite-lived intangible assets are reviewed for impairment on an annual basis (or more frequently if events or circumstances indicate that their carrying value may not be recoverable) and other intangible assets if events or circumstances indicate that their carrying value may not be recoverable. If Granite’s goodwill, indefinite-lived intangible assets, or other intangible assets are determined to be impaired in the future, Granite will be required to record a material, non-cash charge to earnings during the period in which the impairment is determined.

The Merger Agreement contains provisions that limit Layne’s ability to pursue alternatives to the Merger, which could discourage a potential acquirer of Layne from making an alternative transaction proposal or could result in a competing proposal being at a lower price than it might otherwise be and, in certain circumstances, could require Layne to pay Granite a significant termination fee.

The Merger Agreement contains “no shop” provisions that, subject to limited exceptions, require that Layne may not (a) solicit, initiate, cause or knowingly facilitate or encourage the submission of any inquiries, proposals or offers or any other efforts or attempts that constitute or may reasonably be expected to lead to any acquisition proposal (as described in “The Merger Agreement—No Solicitation of Acquisition Proposals” beginning on page 110 of this proxy statement/prospectus), or engage in any discussions or negotiations with respect thereto or otherwise cooperate with or assist or participate in, or knowingly facilitate or encourage, any such inquiries,

- 27 -

proposals, discussions or negotiations, or resolve to or publicly propose to take any of the foregoing actions, (b) approve or recommend, or resolve to or publicly propose to approve or recommend, any acquisition proposal or enter into any Merger Agreement, agreement-in-principle, letter of intent, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other similar agreement relating to an acquisition proposal or enter into any letter of intent, agreement or agreement-in-principle requiring Layne to abandon, terminate or fail to consummate the Merger or (c) (1) withdraw, modify or qualify in a manner adverse to Granite or Merger Sub the recommendation of the Layne Board or the approval or declaration of advisability by the Layne Board of the Merger Agreement and the transactions contemplated thereby (including the Merger) or (2) approve or recommend, or resolve to or publicly propose to approve or recommend, any acquisition proposal.

The Merger Agreement also provides that Layne will be required to pay a termination fee of $16.0 million to Granite upon termination of the Merger Agreement under certain circumstances. These provisions might discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of Layne from considering or proposing an acquisition even if it were prepared to pay consideration with a higher per share market price than that proposed in the Merger, or might result in a potential competing acquiror proposing to pay a lower per share price to acquire Layne than it might otherwise have proposed to pay.

The opinion delivered by Greentech will not reflect changes in circumstances between the date of such opinion and the completion of the Merger.

The Layne Board has not obtained an updated opinion as of the date of this proxy statement/prospectus from Greentech, its financial advisor. Changes in the operations and prospects of Layne or Granite, general market and economic conditions and other factors that may be beyond their control, and on which the opinions were based, may alter the value of Layne or Granite or the prices of Layne Common Stock or Granite Common Stock by the time the Merger is consummated. The opinion does not speak as of the time the Merger will be completed or as of any date other than the date of such opinion. Because Layne does not anticipate asking Greentech to update its opinion, the opinion only addresses the fairness of the Merger Consideration, from a financial point of view, as of the date of such opinion, subject to the various assumptions made, procedures followed, factors considered, and limitations of the review undertaken, qualifications contained and other matters set forth therein. Greentech’s opinion is included as Annex C to this proxy statement/prospectus. For a description of the opinion, please refer to “The Merger—Opinion of Financial Advisor to Layne” beginning on page 81 of this proxy statement/prospectus.

Layne executive officers and directors have financial interests in the Merger that may be different from, or in addition to, the interests of Layne stockholders.

Executive officers of Layne negotiated the terms of the Merger Agreement with their counterparts at Granite, and the Layne Board unanimously determined that the Merger Agreement and the Merger are in the best interests of Layne and its stockholders, approved and declared the Merger Agreement and unanimously recommended that Layne stockholders adopt the Merger Agreement. In considering these facts and the other information contained in this proxy statement/prospectus, you should be aware that Layne’s executive officers and directors have financial interests in the Merger that may be different from, or in addition to, the interests of Layne stockholders. For a detailed discussion of the special interests that Layne’s directors and executive officers may have in the Merger, see “The Merger—Interests of Certain Persons in the Merger” beginning on page 95 of this proxy statement/prospectus.

Risks Related to the Combined Company Following the Merger

The market price of Granite Common Stock and Granite’s results of operations may be affected by factors different from those affecting the market price of Layne Common Stock and Layne’s results of operations.

Layne stockholders will be entitled to receive the Merger Consideration, which is comprised of Granite Common Stock and will thus become Granite stockholders upon the consummation of the Merger. Granite’s

- 28 -

business is different from that of Layne, and Granite’s results of operations, as well as the market price of Granite Common Stock, may be affected by factors different from those affecting Layne’s results of operations and the market price of Layne Common Stock. The market price of Granite Common Stock may fluctuate significantly following the Merger, including as a result of factors over which Granite has no control.

Failure to achieve expected benefits of the Merger and to integrate Layne’s operations with Granite’s could adversely affect Granite following the completion of the Merger and the market price of Granite Common Stock.

Although Granite expects to realize strategic, operational and financial benefits as a result of the Merger, Granite cannot be certain whether, and to what extent, such benefits will be achieved in the future. In particular, the success of the Merger will depend on achieving efficiencies and cost savings, and no assurances can be given that Granite will be able to do so. For example, costs associated with Layne’s legal proceedings and other loss contingencies may be greater than expected (including with respect to current and legacy projects undertaken and liabilities assumed by Layne and businesses that Layne has sold or discontinued). In addition, in order to obtain the benefits of the Merger, Granite must integrate Layne’s operations. Such integration may be complex and the failure to do so quickly and effectively may negatively affect earnings. Granite’s failure to create, or any significant delay in creating, an optimal operational and financial structure for the combined company may result in Granite being unable to realize the expected synergies and other intended benefits from the Merger.

In addition, the market price of Granite Common Stock may decline as a result of the Merger if the integration of Granite and Layne is unsuccessful, takes longer than expected or fails to achieve financial benefits to the extent anticipated by financial analysts or investors, or the effect of the Merger on Granite’s financial results is otherwise not consistent with the expectations of financial analysts or investors.

The pro forma financial statements included in this proxy statement/prospectus are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the Merger.

The pro forma financial statements contained in this proxy statement/prospectus are presented for illustrative purposes only, are based on various adjustments, assumptions and preliminary estimates and may not be an indication of the combined company’s financial condition or results of operations following the Merger for several reasons. See “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 39 of this proxy statement/prospectus. The actual financial condition and results of operations of the combined company following the Merger may not be consistent with, or evident from, these pro forma financial statements. In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the combined company’s financial condition or results of operations following the Merger. Any potential decline in the combined company’s financial condition or results of operations may cause significant variations in the stock price of Granite following the Merger.

Layne stockholders will have a reduced ownership and voting interest in Granite after the Merger and, as a result, will be able to exert less influence over management.

Following the Merger, each Layne stockholder will become a stockholder of Granite with a percentage ownership of Granite after the Merger that is smaller than the stockholder’s percentage ownership of Layne. It is expected that immediately after consummation of the Merger the former stockholders of Layne as a group will own approximately 12% of the outstanding shares of Granite Common Stock on a fully diluted basis, excluding any shares that may subsequently be issued in connection with conversion of the 8.0% Convertible Notes. Because of this, Layne stockholders will have substantially less influence on the management and policies of Granite after the Merger than they now have with respect to the management and policies of Layne.

- 29 -

Granite may be unable to hire and retain sufficient qualified personnel, and the loss of any of its key executive officers could adversely affect Granite.

Granite believes that its future success will depend in large part on its ability to attract and retain highly skilled, knowledgeable, sophisticated and qualified managerial and professional personnel, including, following the Merger, key employees of Layne. Key employees of Granite or Layne may depart for a variety of reasons, including because of issues relating to the difficulty of integration or accelerated retirement as a result of amounts received in connection with the Merger. Accordingly, no assurance can be given that Granite will be able to retain key employees of Granite or, following the Merger, Layne.

The combined company may require additional capital in the future, which may not be available to it on satisfactory terms, if at all.

The combined company will require liquidity to fund its operations and make interest and principal payments on its debt. To the extent that the funds generated by the combined company’s ongoing operations are insufficient to cover its liquidity requirements, it may need to raise additional funds through financings. If the combined company cannot obtain adequate capital or sources of credit on favorable terms, or at all, its business, operating results and financial condition could be adversely affected. Any future equity or debt financing may not be available on terms that are favorable to the combined company, if at all.

Other Risk Factors of Granite and Layne

Granite’s and Layne’s businesses are and will be subject to the risks described above. In addition, Granite and Layne are, and will continue to be, subject to the risks described in Granite’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, and Layne’s Annual Report on Form 10-K for the fiscal year ended January 31, 2018, which is incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 145 of this proxy statement/prospectus.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

A number of the statements made or incorporated by reference in this proxy statement/prospectus are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act, Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements are all statements made or incorporated by reference into this proxy statement/prospectus, other than statements of historical fact. In some cases, forward-looking statements can be identified by terminology such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “will,” “would,” and similar expressions or expressions of the negative of these terms. These statements include statements regarding the intent, belief or current expectations of each of Granite and Layne and their respective subsidiaries, their directors and their officers with respect to, among other things, future events, including the Merger, the respective financial results and financial trends expected to impact each of Granite and Layne prior to the completion of the Merger, or if the Merger is not completed, and expected to impact Granite thereafter, assuming the Merger is consummated.

Forward-looking statements are based upon certain underlying assumptions, including any assumptions mentioned with the specific statements, as of the date such statements were made. Such assumptions are in turn based upon internal estimates and analyses of market conditions and trends, management plans and strategies, economic conditions and other factors. While Granite and Layne believe these expectations, assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond the control of Granite and Layne. By their nature, forward-looking statements and the assumptions underlying them are necessarily subject to risks and uncertainties inherent in projecting future conditions and results. Actual results may differ materially from the current expectations of Granite and Layne depending on a number of factors affecting their businesses and risks associated with the successful execution of the Merger and the integration and performance of their businesses following the Merger. These factors include, but are not limited to, those set forth under “Risk Factors” beginning on page 22 of this proxy statement/prospectus, and those set forth under “Forward-Looking Statements,” “Risk Factors” or any similar heading in the documents incorporated by reference herein.

Granite and Layne caution you not to place undue reliance on the forward-looking statements, which speak only as of the date of this proxy statement/prospectus in the case of forward-looking statements contained in this proxy statement/prospectus, or the dates of the documents incorporated by reference in this proxy statement/prospectus in the case of forward-looking statements made in those incorporated documents. Except as may be required by law, neither Granite nor Layne has any obligation to update or alter these forward-looking statements, whether as a result of new information, future events or otherwise.

Granite and Layne expressly qualify in their entirety all forward-looking statements attributable to Granite or Layne or any person acting on either of their respective behalf by the cautionary statements contained or referred to in this section.

INFORMATION ABOUT GRANITE CONSTRUCTION INCORPORATED

Granite delivers infrastructure solutions for public and private clients primarily in the United States. Granite is one of the largest diversified heavy civil contractors and construction materials producers in the United States. Granite operates nationwide, serving both public and private sector clients. Within the public sector, Granite primarily concentrates on heavy-civil infrastructure projects, including the construction of streets, roads, highways, mass transit facilities, airport infrastructure, bridges, trenchless and underground utilities, power-related facilities, water-related facilities, utilities, tunnels, dams and other infrastructure-related projects. Within the private sector, Granite performs site preparation and infrastructure services for residential development, energy development, commercial and industrial sites, and other facilities, as well as provide construction management professional services. Granite’s business is organized into three reportable business segments. These business segments are: Construction, Large Project Construction and Construction Materials.

The four primary economic drivers of Granite business are (a) the overall health of the U.S. economy; (b) federal, state and local public funding levels; (c) population growth resulting in public and private development; and (d) the need to replace or repair aging infrastructure. A stagnant or declining economy will generally result in reduced demand for construction and construction materials in the private sector. This reduced demand increases competition for private sector projects and will ultimately also increase competition in the public sector as companies migrate from bidding on scarce private sector work to projects in the public sector. In addition, a stagnant or declining economy tends to produce less tax revenue for public agencies, thereby decreasing a source of funds available for spending on public infrastructure improvements. Some funding sources that have been specifically earmarked for infrastructure spending, such as diesel and gasoline taxes, are not as directly affected by a stagnant or declining economy, unless actual consumption is reduced or gasoline sales tax revenues decline consistent with fuel prices. However, even these can be temporarily at risk as federal, state and local governments take actions to balance their budgets. Additionally, fuel prices and more fuel efficient vehicles can have a dampening effect on consumption, resulting in overall lower tax revenue. Conversely, increased levels of public funding as well as an expanding or robust economy will generally increase demand for Granite’s services and provide opportunities for revenue growth and margin improvement.

In connection with entering into the Merger Agreement, Granite received a commitment letter for a new $370 million backstop facility. That backstop facility was obtained because the assumption of Layne’s outstanding debt and letters of credit would exceed the amount of indebtedness permitted under Granite’s then existing credit facility.

In connection with the Merger Agreement, Granite (a) has entered into the Credit Facility Amendment and (b) expects to enter into the NPA Amendment. The Credit Facility Amendment, among other things, (a) exempts Layne and its subsidiaries from the provisions of the Senior Credit Facility that would otherwise require them to guarantee Granite’s obligations under the Senior Credit Facility until the date upon which the 8.0% Convertible Notes have been paid or otherwise satisfied in full, (b) permits liens on certain assets of Layne and its subsidiaries securing the 8.0% Convertible Notes, (c) permits certain indebtedness outstanding under the 4.25% Convertible Notes and the 8.0% Convertible Notes and (d) increases the aggregate amount of uncommitted incremental revolving loans and/or incremental term loans that Granite may request under the Senior Credit Facility up to a maximum of $130,000,000, in each case as more fully disclosed in Granite’s Current Report on Form 8-K filed with the SEC on March 1, 2018. See “Where You Can Find More Information” beginning on page 145 of this proxy statement/prospectus. The NPA Amendment is expected to, among other things, (a) permit the acquisition of Layne pursuant to the Merger Agreement, (b) exempt Layne and its subsidiaries from the provisions of the Note Purchase Agreement that would otherwise require them to guarantee Granite’s obligations under the Note Purchase Agreement until the earliest of the date upon which the 8.0% Convertible Notes have been paid or otherwise satisfied in full or certain other dates, if earlier, (c) permit liens on certain assets of Layne and its subsidiaries securing the 8.0% Convertible Notes and (d) permit certain indebtedness outstanding under the 4.25% Convertible Notes and the 8.0% Convertible Notes.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The accompanying Pro Forma Income Statements for the periods presented combine the historical consolidated statements of income of Granite and Layne, giving effect to the Merger as if it had been completed on January 1, 2017, the beginning of the earliest period presented. The Pro Forma Income Statements assume that Granite, with a fiscal year that ends on December 31, acquired Layne, with a fiscal year that ends on January 31, and are to be read as if the Merger has been completed. The Pro Forma Income Statements for the fiscal year ended December 31, 2017 will include (a) Granite’s fiscal year ended December 31, 2017 and (b) Layne’s fiscal year ended January 31, 2018. The accompanying Pro Forma Balance Sheet as of December 31, 2017 combines the historical consolidated balance sheets of Granite as of December 31, 2017 and Layne as of January 31, 2018, giving effect to the Merger as if it had been completed on December 31, 2017.

The accompanying Pro Forma Financial Statements and related notes were prepared using the acquisition method of accounting with Granite considered the acquirer of Layne. Accordingly, the Merger Consideration to be paid in the Merger has been allocated to assets and liabilities of Layne based upon their estimated fair values as of the date of completion of the Merger. Any amount of the Merger Consideration that is in excess of the estimated fair values of assets acquired and liabilities assumed will be recorded as goodwill in Granite’s balance sheet after the completion of the Merger. The amount of goodwill that will be recorded in connection with the Merger depends on the market price of Granite Common Stock on the date of completion of the Merger. As a result of recent market volatility, the amount of goodwill that is ultimately recorded may vary significantly from the estimated goodwill on the Pro Forma Balance Sheet. As of the date of this proxy statement/prospectus, Granite has not completed the detailed valuation work necessary to arrive at the required estimates of the fair value of the Layne assets to be acquired and the liabilities to be assumed and the related allocation of purchase price, nor has it identified all adjustments necessary to conform Layne’s accounting policies to Granite’s accounting policies. A final determination of the fair value of Layne’s assets and liabilities will be based on the actual net tangible and intangible assets and liabilities of Layne that exist as of the date of completion of the Merger and, therefore, cannot be made prior to that date. Additionally, the value of the Merger Consideration to be paid by Granite to complete the Merger will be determined based on the trading price of Granite Common Stock in accordance with the Merger Agreement. Accordingly, the accompanying unaudited pro forma purchase price allocation is preliminary and is subject to further adjustments as additional information becomes available and as additional analyses are performed. Granite currently expects Construction, Cost of revenue, Selling, general and administrative expenses and amortization of discount and deferred financing costs to be the primary income statement line items that may be impacted by the determination of the final purchase price allocation from resulting amortization of tangible and intangible assets. Similarly, Granite currently expects investments in affiliates, goodwill, deferred income taxes, other noncurrent assets, long term debt, other long term liabilities and additional paid in capital to be the primary balance sheet line items that may be impacted by the final determination of the purchase price allocation. The preliminary unaudited pro forma purchase price allocation has been made solely for the purpose of preparing the accompanying Pro Forma Financial Statements. The preliminary purchase price allocation was based on Granite’s historical experience, data that was available through the public domain and Granite’s due diligence review of Layne’s business. Until the Merger is consummated, both companies are limited in their ability to share information with the other. Upon completion of the Merger, further valuation work will be performed. Increases or decreases in the fair value of relevant balance sheet amounts will result in adjustments to the balance sheet and/or statements of income until the purchase price allocation is finalized. There can be no assurance that such finalization will not result in material changes from the preliminary purchase price allocation included in the accompanying Statements.

The accompanying Pro Forma Financial Statements and related notes are being provided for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or the consolidated balance sheet of Granite would have been had the Merger occurred on the dates assumed, nor are they necessarily indicative of Granite’s future consolidated results of operations or consolidated financial position. The Pro Forma Financial Statements are based upon currently available information and estimates and assumptions that Granite management believes are reasonable as of the date hereof. Any of the factors underlying these estimates and assumptions may change or prove to be materially different, and the estimates and assumptions may not be representative of facts existing at the closing date of the Merger.

- 39 -

The accompanying Pro Forma Financial Statements have been developed from and should be read in conjunction with the audited consolidated financial statements of Granite contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2017, and of Layne contained in its Annual Report on Form 10-K for the fiscal year ended January 31, 2018, which is incorporated by reference in this proxy statement/prospectus.

The historical consolidated financial statements of Layne presented herein have been adjusted by condensing and disaggregating certain line items in order to conform to Granite’s financial statement presentation.

Note 1. Description of the Transaction

On February 13, 2018, Granite and Layne entered into the Merger Agreement pursuant to which, among other things, Merger Sub will be merged with and into Layne, with Layne surviving the Merger as a wholly owned subsidiary of Granite. The Merger was unanimously approved by the Granite Board and the Layne Board and is expected to close promptly following the Special Meeting, subject to the conditions described in the Merger Agreement.

At the Effective Time, each share of Layne Common Stock that is issued and outstanding will be cancelled and automatically converted into the right to receive 0.27 shares of Granite Common Stock. Upon completion of the Merger, former Layne stockholders will own approximately 12% of the outstanding shares of Granite Common Stock on a fully diluted basis (excluding any shares that may subsequently be issued in connection with any conversion of the 8.0% Convertible Notes into shares of Granite Common Stock following the Merger). Further, Granite will expand the size of the Granite Board and designate one director of Layne, who is a director prior to the Effective Time, to fill such vacancy.

Note 2. Basis of Pro Forma Presentation

The accompanying Pro Forma Financial Statements were prepared in accordance with Article 11 of Regulation S-X prescribed by the SEC. The Pro Forma Balance Sheet was prepared using the historical balance sheets of Granite as of December 31, 2017 and Layne as of January 31, 2018. Granite’s fiscal year ends on December 31 and Layne’s fiscal year ends on January 31. The Pro Forma Income Statements were prepared using:

•

Layne’s historical audited consolidated statement of operations for the year ended January 31, 2018; and

•

Granite’s historical audited consolidated statement of operations for the year ended December 31, 2017.

Both Layne’s and Granite’s historical audited financial statements were prepared in accordance with GAAP.

The Pro Forma Financial Statements have been prepared using the acquisition method of accounting for business combinations under GAAP. The acquisition method of accounting is dependent upon certain valuations and other studies, which are currently in progress. The final determination of fair value of assets acquired and liabilities assumed may result in material changes to the Pro Forma Financial Statements.

Upon completion of the Merger, Granite expects to conduct an additional review of accounting policies used to prepare Layne’s historical financial statements to determine if further adjustment or reclassification of Layne’s results of operations, assets or liabilities are required to conform to the accounting policies and classifications used to prepare Granite’s historical financial statements. This review may identify additional differences between the accounting policies of Granite and Layne, which may have a material impact on Granite’s future consolidated financial statements. Other than as disclosed in Note 5 below, we are currently not aware of any significant differences between the accounting policies of Granite and Layne.

- 43 -

The Pro Forma Financial Statements are preliminary, provided for illustrative purposes only and do not purport to represent what Granite’s actual consolidated results of operations or consolidated financial position would have been had the Merger occurred on the date assumed, nor are they indicative of Granite’s future consolidated results of operations or financial position. The actual results reported in periods following the Merger may differ significantly from those reflected in the Pro Forma Financial Statements for a number of reasons, including, but not limited to, differences between the assumptions used to prepare the Pro Forma Financial Statements and actual amounts, cost savings or associated costs to achieve such savings from operating efficiencies, synergies, debt refinancing, or other restructuring that may result from the Merger. Non-recurring items related to the Merger were not included in the Pro Forma Income Statements.

Note 3. Estimate of Consideration Expected to be Transferred

The calculation of the preliminary estimated purchase price for Layne presented below is based on the terms of the Merger. The Pro Forma Financial Statements include various assumptions, including those related to shares of Granite Common Stock to be issued in connection with the Merger and the fair value of Granite Common Stock. The Pro Forma Financial Statements also assume a purchase price of approximately $334 million and that the Merger was completed on April 10, 2018 using a closing price of $56.13 per share of Granite Common Stock.

The following table shows the preliminary estimated fair value of Layne’s assets acquired and liabilities assumed, as of the Effective Time:


	Amount Estimated
	(in thousands)
Cash	$	32,041
Receivables		59,558
Other current assets		76,922
Property and equipment		120,604

Other current liabilities		(105,937	)
Other long-term liabilities		(46,011	)
Non-controlling interests		(48	)

Net Assets Acquired	$	334,406

The following table shows sensitivities to changes in the preliminary estimated purchase price and goodwill resulting from a 10% increase or decrease in the assumed per share price of Granite Common Stock:


	Price of Granite Common Stock		Preliminary Estimated Purchase Price		Estimated Goodwill
	(in thousands, except per share price)
As of April 10, 2018	$	56.13	$	334,406	$	194,675

Note 4. Adjustments to Pro Forma Financial Statements

Adjustments present in the Pro Forma Financial Statements are based on preliminary information and are subject to subsequent changes. The historical consolidated statements of operations and consolidated balance

- 44 -

sheets have been adjusted in the Pro Forma Financial Statements to give effect to pro forma events that are: (1) directly attributable to the Merger; (2) factually supportable; and (3) with respect to the statements of operations, expected to have a continuing impact on the results of operations of the combined company. Additional pro forma adjustments may also be identified through the completion of purchase accounting:

Adjustments to the Pro Forma Balance Sheet

Granite has made the following pro forma adjustments to Layne’s historical balance sheet as of January 31, 2018:

(a)

a fair value increase of $15 million related to investments in affiliates;

(b)

an elimination of Layne’s historical goodwill and the preliminary estimate of goodwill recognized as a result of the Merger, which represents the amount by which the estimated consideration transferred exceeds the fair value of Layne’s assets acquired and the liabilities assumed;

(c)

an adjustment to the net deferred tax assets and liabilities resulting from the adjustments to deferred tax assets and liabilities, based on an estimated statutory tax rate of 25.75%, which includes the federal statutory tax rate, adjusted for the estimated state statutory tax rate. This estimate of the net deferred tax assets and liabilities balance includes the release of the valuation allowance associated with federal net operating loss carryforwards and other federal deferred tax assets that were fully reserved within Layne’s historical financial statements. Granite currently believes that it will have sufficient taxable income to utilize Layne’s federal net operating loss carryforwards prior to expiration. Layne’s federal gross net operating loss carryforwards as of January 31, 2018 were $150.2 million. Those loss carryforwards expire between the fiscal years 2034 and 2038, providing up to 20 years to generate the taxable income that would be required to realize Layne’s federal net operating loss carryforwards. As a result, Granite believes it is more likely than not that federal net operating loss carryforwards and other federal deferred tax assets will be realized. Further, income tax benefit related to the reduction of valuation allowance is not included in the Pro Forma Income Statement. This is preliminary and subject to change based on Granite’s final determination of the fair value of assets acquired and liabilities assumed by jurisdiction; additionally, Granite has revised the statutory tax rate at which these were recorded to account for the statutory tax rate enacted as of December 31, 2017, the date of the Pro Forma Balance Sheet. The table below summarizes the various components of this adjustment:


	December 31, 2017
	(in thousands)
Deferred Tax Asset Valuation Allowance Release	$	41,398
Net Deferred Tax Liability From Fair Value Adjustments		(18,584	)
Deferred Tax Liability Reclassification		(2,130	)

Net Deferred Tax Asset Adjustment	$	20,684

- 45 -

(d)

the estimated fair value of Layne’s identified intangible assets. The following table shows a preliminary estimate of the fair value of those intangible assets and their related average estimated useful lives:


	Estimated Useful Life (in Years)		Estimated Fair Value as of December 31, 2017		Net Book Value as of January 31, 2018		Pro Forma Adjustment
	(in thousands)
Intangible Assets
Backlog		1	$	24,570	$	—	$	24,570
Customer Relationships		5		42,998		—		42,998
Trademarks/Trade Names		10		23,034		910		22,124
Patent/Technology/License Agreements		5		3,686		2,934		752
Non-Competition Agreements		3		2,396	$	—	$	2,396

Total Intangible Assets			$	96,683	$	3,844	$	92,839

Intangible Liabilities
Unfavorable Contracts, net		1	$	6,143	$	—	$	6,143

(e)

the 4.25% Convertible Notes reflect an adjustment of $2.8 million to record the 4.25% Convertible Notes at estimated fair value based on publicly-observed market prices of the notes. The conversion rate of the 4.25% Convertible Notes would result in a value less than the $1,000 principal amount of each 4.25% Convertible Note. The 8.0% Convertible Notes have an “as converted” value that exceeds the principal amount of the 8.0% Convertible Notes, which approximates fair value. The 8% Convertible Notes reflect an adjustment of $30.2 million based upon the market price of Granite Common Stock (as of April 10, 2018) issuable upon conversion of the 8.0% Convertible Notes.

(f)

expenses of $8.6 million incurred by Granite and Layne directly attributable to the Merger. Total expected costs, including those costs already incurred, that are directly attributable to the Merger are estimated to be approximately $31 million. The expenses that Granite and Layne may ultimately incur may differ materially from this amount. These expenses include fees for investment banking, advisory, legal, valuation, and other professional fees. As these expenses will not have a continuing impact, Granite has not shown these estimated expenses in the Pro Forma Income Statements. No material Merger-related expenses were incurred by Granite and Layne during the periods covered by the historical financial statements; and

(g)

the elimination of Layne’s historical equity and the estimated consideration of $334 million, which includes the issuance of $302 million in shares of Granite Common Stock to Layne stockholders, and $32.5 million in cash for the Layne Stock Options, Layne RSUs and Layne PSUs. The number of Layne Stock Options used for calculating the amount of cash payable excludes 212,098 of Layne Stock Options, which have exercise prices that exceed the per share merger consideration based on the market price of Granite Common Stock as of April 10, 2018. Based on the Granite Common Stock Price, these values may differ when the Merger is completed. The actual number of shares of Granite Common Stock issued to Layne stockholders and cash paid for Layne Stock Options, Layne RSUs and Layne PSUs upon closing of the Merger will be based on the actual number of shares of Layne Common Stock outstanding at the Effective Time, and the fair value of those shares will be based on the trading price of Granite Common Stock at that time.

Adjustments to Pro Forma Income Statements

Granite has made the following adjustments to Layne’s historical income statement for the fiscal year ended January 31, 2018:

(h)

additional amortization of intangible assets which will be acquired based on the preliminary estimated fair value and useful lives expected to be recorded as a result of the Merger. For estimated intangible

asset values and the associated useful lives, see note (d) under “—Adjustments to Pro Forma Balance Sheet” above. The following table shows a preliminary estimate of the amortization of the fair value of those intangible assets based on their related estimated useful lives:


	Year Ended December 31, 2017
	(in thousands)
Cost of revenues	$	18,428
Selling, general and administrative	$	12,439

(i)

amortization of the adjustment from carrying value to fair value of the Convertible Notes;

(j)

tax effects of the pro forma adjustments based on a statutory tax rate of 39%, which reflects the federal and state tax rate in effect during the period presented. Due to the 2017 Tax Cuts and Jobs Act, future tax provision may materially differ from the current provision; and

(k)

the following table shows the calculation of pro forma combined basic and diluted net income per share of Granite Common Stock, after giving effect to the preliminary estimated number of shares of Granite Common Stock to be issued to Layne stockholders in the Merger, for the year ended December 31, 2017 (the shares of Granite Common Stock issuable upon conversion of the Convertible Notes are not included in the table below because the issuance of the shares would be anti-dilutive using the “if converted” method):


	Year Ended December 31, 2017 Basic		Year Ended December 31, 2017 Diluted
	(in thousands, except per share amounts)
Pro forma net income attributable to stockholders	$	61,300	$	61,300
Weighted average shares of Granite Common Stock outstanding		39,795		40,372
Shares of Layne Common Stock converted to shares of Granite Common Stock		5,378		5,378

Pro forma weighted average shares of Granite Common Stock outstanding		45,173		45,750

Pro forma net income per share of Granite Common Stock	$	1.36	$	1.34

(l)

reclassification of $99 million of the 8.0% Convertible Notes from long-term debt to current maturities of long-term debt because the Pro Forma Balance Sheet is as of December 31, 2017 and Granite intends to accelerate the maturity of the 8.0% Convertible Notes to August 15, 2018. Pursuant to the terms of the indenture governing the 8.0% Convertible Notes, the notes will mature on May 1, 2019, unless earlier paid or the maturity date is accelerated to August 15, 2018, which acceleration will occur if all of the outstanding 4.25% Convertible Notes have not been redeemed, repurchased, discharged, or otherwise retired prior to August 15, 2018 and the maturity date for the 4.25% Convertible Notes has not been extended to a date after October 15, 2019. Granite intends to redeem the 4.25% Convertible Notes on the original maturity date of November 15, 2018, which will result in the maturity date of the 8.0% Convertible Notes being accelerated to August 15, 2018.

Note 5. Reclassifications

The Layne historical unaudited condensed balance sheet and statement of operations have been conformed to Granite’s presentation of the respective statements. Granite has made the following reclassification to Layne’s historical balance sheet as of January 31, 2018 and statement of operations for the fiscal year ended January 31, 2018:

(m)

reclassification of $27 million of depreciation and amortization from separate presentation in Layne’s historical statement of operations to cost of revenue and selling, general and administrative expenses in the amounts of $25 million and $2 million, respectively.

UNAUDITED COMPARATIVE PER SHARE DATA

The following table shows, for the year ended December 31, 2017 for Granite and for the year ended January 31, 2018 for Layne, historical and pro forma equivalent per share data for Layne Common Stock and historical and pro forma combined per share data for Granite Common Stock. The information in the table is derived from each of Layne’s and Granite’s respective historical consolidated financial statements incorporated by reference herein, as well as the Pro Forma Financial Statements included elsewhere herein. The pro forma equivalent per share data and the pro forma combined per share data assume that Granite, with a fiscal year that ends on December 31, acquired Layne, with a fiscal year that ends on January 31, and are to be read as if the Merger has been completed on December 31, 2017.

The pro forma equivalent information shows the effect of the Merger from the perspective of a holder of Layne Common Stock. The information was computed by multiplying the pro forma combined income from continuing operations per share for the year ended December 31, 2017 for Granite and for the year ended January 31, 2018 for Layne, respectively, and pro forma combined book value per share as of December 31, 2017 by the Exchange Ratio.

The pro forma combined data below is presented for illustrative purposes only. The pro forma adjustments to the income statement data are based on the assumption that the Merger was completed on January 1, 2017, and the pro forma adjustments to the balance sheet data are based on the assumption that the Merger was completed on December 31, 2017.

Either company’s actual historical financial condition or results of operations may have been different had the companies always been combined. You should not rely on this information as being indicative of the historical financial condition and results of operations that would have actually been achieved or of the future results of Granite after the completion of the Merger.

You should read the information below together with the historical consolidated financial statements and related notes of each of Granite and Layne, which are incorporated by reference in this proxy statement/prospectus, and with the information under the heading “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 39 of this proxy statement/prospectus.

Dividend Policies

Layne has not paid dividends since its initial public offering in 1992, and does not anticipate paying any cash dividends on its common stock in the foreseeable future. The Merger Agreement restricts the ability of Layne to declare or pay dividends prior to the consummation of the Merger.

Granite has paid quarterly cash dividends since the second quarter of 1990, and expects to continue to do so. However, declaration and payment of dividends is within the sole discretion of the Granite Board, subject to limitations imposed by Delaware law and compliance with Granite’s credit agreements (which allows dividends so long as Granite has at least $150 million in unencumbered cash and cash equivalents and marketable securities), and will depend on our earnings, capital requirements, financial condition and such other factors as the Granite Board deems relevant. As of December 31, 2017, Granite had unencumbered cash, cash equivalents and marketable securities that exceeded these limitations.

You should carefully read this entire proxy statement/prospectus and the documents incorporated herein by reference, including the full text of the Merger Agreement, which is attached as Annex A, for a more complete understanding of the Merger. In addition, important business and financial information about each of Granite and Layne is incorporated into this proxy statement/prospectus by reference and is included in the Annexes hereto. See “Where You Can Find More Information” beginning on page 145 of this proxy statement/prospectus.

Background of the Merger

The Layne Board and the Granite Board each regularly reviews its results of operations, competitive positions and strategic alternatives. From time to time, both Layne and Granite also evaluate potential transactions that would further their respective strategic objectives.

As part of its regular evaluation of strategic opportunities, Layne, directly or through its advisors, held discussions with various potential strategic and financial counterparties during the two years prior to the signing of the Merger Agreement. These discussions related primarily to an evaluation of a potential sale of either all or a portion of Layne’s business to strategic counterparties or financial sponsors, the acquisition of businesses from other companies, potential equity investments in Layne by financial sponsors and a refinancing process for the Convertible Notes.

In February 2016, Michael J. Caliel, Layne’s President and Chief Executive Officer, and J. Michael Anderson, Layne’s Senior Vice President and Chief Financial Officer, met with representatives of an international infrastructure services provider serving the water and other industries (“Company A”) regarding Company A’s potential acquisition of Layne. Throughout the spring of 2016, Layne management participated in various discussions with representatives of Company A regarding the potential acquisition, including conducting in-person discussions with Company A’s management team and evaluating potential synergies that potentially could be achieved through combining businesses of Layne and Company A.

In the spring of 2016, Layne participated as a potential bidder in a sale process conducted by a water infrastructure services company (“Company B”). At that time, representatives of Layne management engaged in discussions with representatives of a private equity firm focused on making controlling equity investments in the power and infrastructure sectors (“Company C”) regarding a potential strategic investment by Company C in Layne to finance the acquisition of Company B. Layne management continued to evaluate a potential transaction with Company B through mid-2016. However, in June 2016, Layne terminated discussions with Company B because Layne management determined the cost of capital associated with pursuing an acquisition of Company B, including the financing terms proposed by Company C, were too high and dilutive to existing Layne stockholders. In connection with terminating its pursuit of Company B, Layne terminated discussions of the financing transaction under consideration with Company C.

In the fall of 2016, Company A determined that a potential acquisition of Layne’s full business was not advisable given the limited amount of potential synergies between the businesses. Layne and Company A continued to evaluate a potential acquisition by Company A of Layne’s Inliner division throughout the fall of 2016. However, Layne management concluded that Company A’s valuation of the Inliner division was insufficient and the parties mutually terminated discussions relating to a potential transaction.

Commencing in September 2016, Layne management engaged in various discussions with representatives of a company engaged in providing water management solutions to oilfield operators across North America (“Company D”) regarding a potential business combination. In connection with evaluating a potential transaction, Layne management and representatives of Company D met periodically between September 2016 and early 2017 to discuss the structure and terms of a potential transaction.

- 63 -

In October 2016, a financial advisory firm that previously had acted as Layne’s financial advisor in connection with a prior transaction proposed to the Layne Board and Layne management that Layne engage in a refinancing process related to the Convertible Notes. The financial advisor observed that Layne might wish to consider pursuing a sale of its Inliner division or, as an alternative, a sale of Layne’s entire business in the event Layne was unable to achieve a refinancing on acceptable terms.

Granite identified Layne as a potential acquisition candidate in connection with Granite’s regular evaluation of strategic opportunities based upon Layne’s size and the nature of its existing businesses. Granite considered Layne as an attractive acquisition candidate because it further diversified Granite’s operations and significantly expanded Granite’s water services business.

In the fall of 2016, James Roberts, Granite’s President and Chief Executive Officer, emailed Mr. Caliel to arrange a time to meet in person. On November 7, 2016, Mr. Roberts met with Messrs. Caliel and Anderson. During that meeting, Mr. Roberts raised the possibility of a strategic transaction involving Granite and Layne. To facilitate further discussion, on November 15, 2016, Layne and Granite entered into a customary confidentiality agreement that also included customary standstill provisions.

On November 29, 2016, senior management from Granite and Layne, together with representatives from Granite’s then financial advisors, met in Phoenix, Arizona for in-person due diligence meetings. At that meeting, senior management from each of Granite and Layne presented an overview of their respective businesses.

On December 22, 2016, Mr. Roberts sent Mr. Caliel a letter proposing that Granite acquire all outstanding shares of Layne Common Stock based on an implied value of $11.75 per Layne share (representing a 7.2% premium to the closing price of Layne Common Stock on December 22, 2016), payable either in all cash or in a combination of cash and shares of Granite Common Stock (the “December 2016 Proposal”). The letter noted that the December 2016 Proposal was subject to due diligence, Granite Board approval and negotiation of an acceptable merger agreement. The letter also noted that the per share price took into account the make-whole premiums that would need to be paid under the 8.0% Convertible Notes.

Throughout December 2016 and early January 2017, Layne management, in consultation with the Layne Board, evaluated the December 2016 Proposal but elected not to pursue the December 2016 Proposal based on Layne management’s focus on addressing certain operational matters at the time as well as its determination that the consideration offered did not appropriately reflect the value of Layne’s business. Accordingly, on January 9, 2017, Mr. Caliel telephoned Mr. Roberts and informed him that Layne was not interested in pursuing a transaction at the proposed valuation. On January 31, 2017, Mr. Roberts telephoned Mr. Caliel to inform him that Granite may be willing to consider an all-stock transaction at a higher valuation in the mid-$12 per share range. After discussions with members of Layne management, Mr. Caliel telephoned Mr. Roberts on February 9, 2017 and informed him that Granite’s proposed valuation was still inadequate and, given prevailing market conditions and its need to focus on addressing certain operational matters, Layne had decided to not engage in further discussions with Granite at that time.

Throughout early 2017, Layne management continued their ongoing evaluation of Layne’s business and regularly reviewed and assessed Layne’s strategic and financial alternatives in light of developments in Layne’s business, in the sectors in which Layne competes, in the economy generally and in the financial markets. Throughout the course of this evaluation, Layne management and members of the Layne Board regularly interfaced with one another to review, analyze and provide input on Layne’s strategic and operational initiatives.

In February 2017, a financial advisory firm, on behalf of Company B, contacted Mr. Caliel to gauge Layne’s interest in resuming discussions regarding a potential strategic transaction involving Company B.

During this period, Layne continued to evaluate potential business combinations with Company B and Company D. In April 2017, discussions with Company D were terminated because Company D was pursuing

- 64 -

another transaction at the time that aligned more closely with Company D’s operational focus and asset base. Company D completed this transaction in 2017.

On April 6, 2017, the Layne Board held a regular meeting at which members of Layne management were also present. During this meeting, Messrs. Caliel and Anderson discussed with the Layne Board the possibility of engaging an investment banking firm to assist with Layne’s strategic and refinancing analysis. The Layne Board designated two directors, Alan P. Krusi and Nelson Obus, to oversee the strategic review and refinancing processes and the selection of an investment banking firm. The Layne Board selected Mr. Krusi because of his experience leading strategic transactions, including his tenure as the President, Strategic Development of AECOM Technology Corporation (“AECOM”), a global provider of integrated professional and construction management services, where he oversaw AECOM’s merger and acquisition activities. The Layne Board selected Mr. Obus because of his financial expertise and managerial experience gained in leadership roles in investment management companies.

From April 2017 through early May 2017, Layne interviewed and received proposals from three investment banking firms regarding strategic and financial advisory services. On May 5, 2017, Messrs. Krusi and Obus, along with members of Layne’s management team, including Mr. Caliel, Mr. Anderson and Steven F. Crooke, Senior Vice President, Chief Administrative Officer & General Counsel of Layne, met with representatives of Greentech Capital Advisors, LLC (“Greentech”) to discuss the possibility of Greentech providing certain financial advisory services to Layne, including evaluating potential business combination opportunities and exploring a refinancing of the Convertible Notes. As part of its evaluation of Greentech’s advisory services, Layne management asked Greentech to provide an evaluation of a potential strategic transaction with Company B, as well as an analysis of Layne’s standalone business and refinancing options. Layne formally engaged Greentech on June 23, 2017, after consultation with Messrs. Krusi and Obus.

On May 1, 2017, Layne announced the completion of the sale of its Heavy Civil business, which further allowed Layne management to streamline its operations and focus on its core businesses.

On May 31, 2017, at a regularly scheduled in-person meeting of the Layne Board, representatives of Greentech presented to the Layne Board an initial assessment of a strategic transaction with Company B. The Layne Board authorized Layne’s management team to further analyze a potential transaction with Company B, including the submission of a non-binding offer to acquire Company B. In June 2017, Layne management sent Company B a non-binding indication of interest. However, Company B determined not to pursue a transaction with Layne and ultimately suspended its sale process.

During the summer of 2017, Layne management worked with representatives of Greentech to develop and analyze various potential strategic transactions. Layne management and Greentech representatives commenced the strategic review process by (a) analyzing historical business unit level financial statements of all of Layne’s operations; (b) reviewing Layne’s internal business unit budgets and forecasts; and (c) after studying such materials, interviewing operating management of Layne’s three business units. The representatives of Greentech also reviewed certain financial information regarding Layne’s business, including Layne’s historical and forecasted unallocated operating expenses at the corporate level, liquidity position, projected cash flow from operations and debt terms and near-term maturities. Layne management and the representatives of Greentech then prepared a framework to assess the operating cash flow of each business unit, the near-term required capital investment to support the business, available refinancing alternatives based on market conditions at the time and potential acquisition targets.

During this period, members of the Layne Board also communicated with Layne management and served as a resource for Layne management to discuss strategic and operational matters. These matters included evaluating potential transaction opportunities with a number of financial and strategic counterparties. On July 11, 2017, the Layne Board held a special meeting at which members of Layne management and representatives of Greentech were also present. During that meeting, representatives of Greentech presented to the Layne Board a financial

- 65 -

analysis of Layne’s business, including an outline of a process to refinance Layne’s Convertible Notes and a review of strategic transactions potentially available to Layne. These transactions primarily included raising growth capital from new and existing sources of capital and evaluating potential acquisition, sale and expansion opportunities relating to one or more divisions of Layne’s business, as well as acquisitions of private company targets. Representatives of Greentech also reviewed with the Layne Board earnings projections and preliminary valuation estimates for each of Layne’s divisions and a preliminary valuation overview for the entire Layne business, based on financial projections provided by Layne management to Greentech.

On August 31, 2017, at a regular meeting of the Layne Board at which members of Layne management and representatives of Greentech were also present, representatives of Greentech provided the Layne Board with an analysis of strategic options related to Layne’s Water Resources division. These options included potentially repositioning the business segment to focus more directly on recurring revenue streams, pursuing acquisitions of bolt-on products or services, pursuing a transformational acquisition, selling the business unit or continuing with the standalone plan.

In evaluating these strategic alternatives for Layne, Greentech determined that any change in strategic direction for Water Resources would take significant time and divert management attention from Layne’s existing operations, as the implementation of certain growth strategies would require significant additional capital and might result in only limited valuation uplift potential compared to Layne’s existing business. In addition, the representatives of Greentech discussed with the Layne Board the fact that Layne operates in three distinct business lines—Water Resources, Mineral Services and Inliner—that have limited operating synergies with one another. Layne management and representatives of Greentech also discussed with the Layne Board the relatively new water midstream business and the significant capital investment required to meaningfully grow that business. In reviewing Layne’s capital structure and near-term debt maturities, lack of recent and projected free cash flow and the challenges of operating three distinct businesses, Greentech observed that the need to deleverage and generate cash for investments in the businesses, coupled with the benefits of a more focused business portfolio, warranted exploring a sale of one or more of Layne’s businesses during the ongoing strategic review process.

Layne management and the representatives of Greentech determined that targeted acquisitions for Layne’s Inliner division could be a logical way to accelerate the revenue growth of Layne’s business. Greentech representatives also provided an overview of its outreach to potential acquisition targets for Layne’s Inliner division, who had been identified collectively by Layne management and the representatives of Greentech. This outreach led to discussions with a provider of underground contracting services to water and wastewater customers in North America (“Company E”) and with a provider of water infrastructure services to customers in the United States (“Company F”) regarding a potential combination with Layne’s Inliner division. However, after initial discussions, Layne terminated discussions with each of Company E and Company F in light of other capital demands on Layne’s business, including the refinancing process for the Convertible Notes.

Layne management continued to analyze various strategic alternatives with representatives of Greentech throughout the summer of 2017, including the refinancing process for the Convertible Notes. This evaluation included discussions between representatives of Greentech and various financial sponsors, including representatives of a private equity firm focused on investing in energy infrastructure in North America (“Company G”), a private equity firm focused on investments and acquisitions in smaller middle-market companies across a range of industries (“Company H”), and a mid-market focused private equity firm with a focus on the industrial sector (“Company I”), regarding potential capital investments by such counterparties in Layne’s business. After Layne management engaged in initial discussions with Company G, the parties determined not to further evaluate a potential transaction. In addition, after initial discussions with representatives of Greentech, Company H and Company I elected not to participate in any further strategic evaluation of Layne’s business.

Throughout the summer and fall of 2017, Layne management continued to advance the refinancing process related to the Convertible Notes. Throughout this process, Layne engaged with various institutional bondholders

- 66 -

who owned a portion of the Convertible Notes regarding the terms of a potential refinancing and exchanged preliminary term sheets with such bondholders. During this process, Layne management determined that the cost of capital associated with the proposals it had received to refinance the Convertible Notes, including the interest and conversion rates requested by institutional bondholders, was high. However, given the need to address the near-term maturity of the Convertible Notes, Layne continued to engage its existing bondholders in refinancing discussions and utilized a financial advisory firm to assist in reviewing other refinancing options and potential capital providers.

Despite the cessation of discussions in February 2017 between Granite and Layne regarding a potential strategic transaction, Granite senior management continued to monitor Layne’s publicly available financial and operational information.

On September 11, 2017, Mr. Roberts telephoned Mr. Caliel to gauge Layne’s interest in participating in further discussions regarding a potential transaction with Granite. Mr. Caliel relayed the Layne Board’s concern that a transaction process may distract Layne management from addressing more pressing operational matters related to its business, including a refinancing the Convertible Notes. However, Mr. Caliel expressed that he would be willing to discuss further to determine if a viable transaction opportunity existed. Accordingly, on September 27, 2017, Mr. Roberts, Jigisha Desai, Granite’s Vice President, Corporate Finance and Treasurer, and Messrs. Caliel and Anderson met in person in The Woodlands, Texas. During that meeting, Granite management reiterated Granite’s interest in pursuing a potential transaction with Layne and Layne management provided an updated overview of Layne’s business.

On October 9, 2017, the Layne Board held a special meeting at which members of Layne management were also present. During that meeting, Messrs. Caliel and Anderson provided the Layne Board with an update regarding Layne’s evaluation of a refinancing process with respect to the Convertible Notes. Messrs. Caliel and Anderson also reviewed with the Layne Board various alternative strategic transactions under consideration, including (a) potential asset or private company acquisitions for Layne’s Inliner division, (b) investment opportunities for Layne’s Water Resources division and (c) an analysis of potential financing options.

On October 23, 2017, at a special meeting of the Layne Board, Mr. Anderson provided a further update to the Layne Board regarding the refinancing process for the Convertible Notes and an analysis of potential financing options.

On October 25, 2017, the Granite Board held a meeting at which members of Granite senior management were also present. During that meeting, senior management provided the Granite Board with a review of its evaluation of a potential transaction involving Layne, including a review of potential synergies and performance metrics that could be achieved through the transaction with Layne. After discussions and deliberations, the Granite Board directed Granite senior management to pursue a potential transaction with Layne.

On October 30, 2017, Mr. Roberts called Mr. Caliel to inform him that he would be receiving a letter containing a written proposal for Granite to acquire Layne. This proposal contemplated a transaction in which Granite would acquire all outstanding shares of Layne Common Stock in an all-stock transaction (the “October 2017 Proposal”). The letter proposed an exchange ratio that would value Layne Common Stock at $15.25 per share (representing a 14.1% premium to the closing price of Layne Common Stock on October 30, 2017). The letter noted the proposal was subject to due diligence, Granite Board approval and negotiation of an acceptable merger agreement.

Following the receipt of the October 2017 Proposal, Mr. Caliel telephoned Mr. Roberts to discuss the October 2017 Proposal. As part of that discussion, Mr. Roberts noted the limited information Granite had regarding Layne’s operations and prospects.

On November 1, 2017, the Layne Board held a special meeting at which members of Layne management and representatives of Greentech were also present. During this meeting, Messrs. Caliel and Anderson provided

- 67 -

the Layne Board with a progress report with respect to the refinancing process related to the Convertible Notes. Mr. Caliel also reviewed the October 2017 Proposal with the Layne Board, including Granite’s previous interest in acquiring Layne and its renewed interest arising from Layne’s improved business outlook. The Layne Board expressed its view that the October 2017 Proposal was inadequate but authorized Layne management to conduct diligence sessions with Granite to enable Granite to better understand Layne’s business and opportunities and potentially submit an improved proposal. As a result, Messrs. Roberts and Caliel agreed to in-person meetings of Layne’s and Granite’s management teams so that Layne could provide Granite with additional information to assist Granite in evaluating Layne.

On November 27, 2017, senior management from Granite and Layne, together with representatives from Perella Weinberg and Greentech, met in Austin, Texas for an in-person due diligence meeting. At this meeting, senior management from Layne presented an overview of its business, including internal financial analyses and forecasts. Following this meeting, Layne management, in consultation with members of the Layne Board, decided to postpone certain aspects of the refinancing process with respect to the Convertible Notes in order to focus on evaluating a potential transaction with Granite, recognizing that a sufficient period still existed prior to the maturity of the Convertible Notes to allow Layne to refinance them if discussions with Granite were to stall.

On November 30, 2017, the Layne Board held a regular meeting at which members of Layne management and representatives of Greentech were also present. During this meeting, Mr. Caliel provided an update regarding the recent diligence sessions with Granite. Representatives of Greentech then provided an update to the Layne Board regarding its ongoing analysis of a potential combination with Granite and certain alternative transactions under consideration, including a review of the limited interest expressed by prior potential counterparties in pursuing a transaction with Layne as well as (a) potential acquisitions by Layne, (b) a sale of one or more divisions of Layne’s business and (c) potential combinations with public and private businesses. Representatives of Greentech also provided the Layne Board with preliminary valuation and accretion and dilution analyses related to a potential transaction with Granite. The Layne Board recommended that Layne management continue to evaluate a potential transaction with Granite and conduct “reverse” due diligence on Granite’s business.

Based on the due diligence conducted to date and the forecasts provided by Layne, on December 12, 2017, Mr. Roberts, on behalf of Granite, sent Mr. Caliel and David A.B. Brown, the Chairman of the Layne Board, a letter proposing that Granite acquire all outstanding shares of Layne Common Stock for $16.25 per share (representing a 35.4% premium to the closing price of Layne common stock on December 12, 2017), with the consideration comprised of shares of Granite Common Stock (the “First December 2017 Proposal”). The First December 2017 Proposal was conditioned on further due diligence, Granite Board approval and negotiation of an acceptable merger agreement.

On December 14, 2017, the Layne Board held a special meeting at which members of Layne management and representatives of Greentech and Stinson Leonard Street LLP, Layne’s outside legal counsel (“Stinson”), were also present. During this meeting, Mr. Caliel provided a summary of the First December 2017 Proposal and representatives of Greentech provided an analysis of the First December 2017 Proposal to the Layne Board. In connection with its analysis, representatives of Greentech provided a preliminary overview of the strategic fit between Layne and Granite’s operations, as well as an analysis of Layne’s valuation and of Granite’s stock price performance. Representatives of Greentech also provided an updated summary and analysis with respect to various alternative transactions under consideration, including a review of (a) potential acquisitions by Layne, (b) a sale of one or more divisions of the Layne business and (c) potential combinations with public and private businesses. The representatives of Greentech reviewed the list of other potential strategic acquirers of Layne, many of whom were engaged in periodic discussions with Layne and with Greentech as part of Greentech’s ongoing industry coverage efforts. The representatives of Greentech stated that they had tested the interest in a strategic transaction with Layne during 2017 with ten such companies who they believed were the most likely interested parties, and confirmed that nine had either expressly or implicitly indicated that they had no interest in exploring strategic alternatives with respect to Layne. The representatives of Greentech offered their view that the value of additional strategic outreach prior to entering into exclusivity and reverse due diligence with Granite

- 68 -

was likely to be limited given the fact that (a) Layne had received limited interest from a prior check of the parties most likely to be interested in a transaction involving Layne and (b) in numerous conversations with potential counterparties, Layne’s capital intensive and diverse range of operations had been cited as a concern in integrating and developing Layne’s business. In addition, representatives of Greentech observed that, notwithstanding the fact that the price of Layne Common Stock had experienced significant declines during periods of 2017, Layne management had not been approached by any counterparty other than Granite regarding a potential acquisition of Layne’s business. During this meeting, the Layne Board also had preliminary discussions regarding the ability to use a “collar” structure in an all-stock transaction and requested that Greentech and Stinson continue to evaluate that mechanism in the event discussions with Granite continued.

After discussion, the Layne Board recommended that Layne management decline the First December 2017 Proposal but authorized Layne management to continue to negotiate with Granite to obtain a more favorable proposal for Layne and its stockholders, with an implied valuation of at least $17.00 per share. The Layne Board also recommended that legacy Layne stockholders have appropriate representation on the Granite Board. In connection with this process, the Layne Board delegated authority to Mr. Brown, Mr. Krusi and Mr. Obus to consult with management with respect to a potential transaction with Granite.

On December 18, 2017, Mr. Roberts and Ms. Desai, on behalf of Granite, and Mr. Caliel and Mr. Anderson, on behalf of Layne, participated in a telephone conversation in which they discussed the possibility of a strategic transaction in which Granite would acquire all outstanding shares of Layne Common Stock for $17.00 per share (representing an approximate 32% premium to the closing price of Layne common stock on December 18, 2017), subject to a “collar” provision to be agreed by the parties that would protect Layne stockholders from a potential decrease in the value of Granite Common Stock.

On December 19, 2017, Messrs. Brown and Obus, as representatives of the Layne Board, participated in a special meeting at which members of Layne management and representatives of Greentech and Stinson were also present. During this meeting, Mr. Caliel provided a summary of the December 18, 2017 discussions with Granite. Representatives of Greentech and Stinson explained the concept of a collar mechanism, and representatives of Greentech provided a review of precedent transactions since 2015 involving a collar mechanism, including the observation that a substantial majority of all-stock transactions did not include a collar mechanism, and a general discussion of potential collar terms. The Layne Board observed that it would be advisable for Layne management and representatives of Greentech to continue to evaluate a collar mechanism despite the lack of significant market precedent.

On December 22, 2017, Ms. Desai telephoned Mr. Anderson and confirmed Granite’s willingness to pursue a potential transaction with Layne based on the terms discussed during the December 18, 2017 telephone conference, including an implied valuation of Layne Common Stock of $17.00 per share, subject to a collar to be determined (the “Second December 2017 Proposal”). On December 26, 2017, Mr. Roberts called Mr. Caliel to reaffirm the terms of the Second December 2017 Proposal.

On December 27, 2017, the Layne Board held a special meeting at which members of Layne management and representatives of Greentech and Stinson were also present. During this meeting, Messrs. Caliel and Anderson and representatives of Greentech presented an analysis of the Second December 2017 Proposal to the Layne Board. In connection with this presentation, Mr. Caliel discussed with the Layne Board the terms of the Second December 2017 Proposal, including the concept of a collar with respect to the exchange ratio and Granite’s request for a period of exclusivity to conduct confirmatory due diligence on Layne. Representatives of Greentech provided the Layne Board with its analysis of the Second December 2017 Proposal, including a discussion of market conditions and opportunities, potential alternative transactions previously reviewed with the Layne Board, a review of peer transactions and an analysis of each company’s recent and historical trading activity. Among other considerations, the Layne Board also discussed with Layne management and Layne’s advisors the standalone prospects of Layne, the all-stock consideration and the need to continue thorough reverse due diligence on Granite. The Layne Board discussed with Layne management the significance of reverse due diligence, particularly in light of the all-stock consideration reflected in the Second December 2017 Proposal. On

- 69 -

December 28, 2017, the Layne Board authorized Layne management to agree to an exclusive negotiating period with Granite lasting until February 15, 2018 (provided that Granite reaffirm in writing its interest in pursuing a transaction with Layne at the $17.00 per share valuation on February 1, 2018) on the basis of the terms reflected in the Second December 2017 Proposal to allow the parties to complete confirmatory due diligence on each other. In connection with the reverse due diligence process, the Layne Board authorized the formation of a special committee of the Layne Board, comprised of Mr. Krusi and John T. Nesser III (the “Layne Special Committee”), to consult with management with respect to the reverse diligence process and any further negotiations with Granite. The Layne Board selected Mr. Krusi as a result of his role leading strategic transactions at AECOM and the familiarity he developed with the construction industry at AECOM and as Chief Executive Officer and President of Earth Tech, Inc., a global engineering and construction firm. The Layne Board selected Mr. Nesser because of his executive, corporate and legal experience, including 14 years of experience at McDermott International, a public international engineering and construction company, where Mr. Nesser served in various roles including Chief Operating Officer, Chief Administrative and Legal Officer, and General Counsel. The Layne Board also authorized Layne to retain Deloitte to support the reverse diligence process and to engage Latham & Watkins to provide legal advisory services in connection with the evaluation of a potential transaction.

On December 28, 2017, Mr. Caliel notified Mr. Roberts that Layne would be willing to enter into a customary exclusivity agreement with Granite related to Granite’s acquisition of all of the outstanding Layne Common Stock in an all-stock transaction based on an implied value of $17.00 per Layne share (the “Proposed Transaction”). Following this discussion, Mr. Roberts provided Mr. Caliel with a draft exclusivity agreement.

On December 31, 2017, Messrs. Brown, Krusi and Obus, as representatives of the Layne Board, participated in a special meeting at which members of Layne management, representatives of Greentech, Stinson and Latham & Watkins were also present. During this meeting, Mr. Caliel provided a summary of his December 28, 2017 discussion with Mr. Roberts, including the request for an exclusivity agreement. Representatives of Latham & Watkins reviewed the exclusivity agreement and certain proposed revisions thereto with the representatives of the Layne Board present, who directed Layne management to finalize negotiation of the exclusivity agreement.

Following these discussions, Granite and its legal counsel, Jones Day, and Layne and its legal counsel, Latham & Watkins, negotiated an exclusivity agreement that provided, among other things, that Layne would not negotiate a potential transaction with any third party until the earliest of: (a) the date of execution of a definitive agreement providing for the Proposed Transaction; (b) the date upon which the parties mutually agree in writing to terminate the exclusivity agreement; (c) the time at which Granite reduces, or proposes a reduction in, the $17.00 per share valuation of Layne Common Stock; and (d) 6:00 p.m. Central time on February 13, 2018. The exclusivity agreement also required that Granite reaffirm in writing its interest in pursuing a transaction with Layne at the $17.00 per share valuation on February 1, 2018.

On January 8, 2018, Mr. Caliel and Mr. Roberts discussed each company’s expectations with respect to the upcoming diligence sessions. During this discussion, Mr. Caliel noted to Mr. Roberts the Layne Board’s recommendation that legacy Layne stockholders have representation on the Granite Board given their familiarity with Layne’s business.

Following the signing of the exclusivity agreement through and including the signing of the Merger Agreement on February 13, 2018, Granite and Layne, together with their respective financial and legal advisors, conducted due diligence reviews of each other. Messrs. Brown, Krusi and Obus recommended, and the Layne Board concurred in, the engagement of Deloitte to conduct an analysis of contracts and percentage of completion accounting, backlog, potential exposures on projects, quality of earnings and tax considerations as part of the reverse due diligence process. Throughout this period, members of Layne management and its outside advisors provided regular updates to the Layne Special Committee as well as to the full Layne Board, and conducted additional due diligence at the request of the Layne Special Committee.

- 70 -

In connection with those diligence reviews, from January 9 through January 11, 2018, Granite, Layne and their respective financial, legal and transaction advisors met in Houston, Texas for in-person due diligence meetings. At that meeting, senior management from each of Granite and Layne presented an overview of their respective businesses, including internal financial analyses and forecasts. These diligence sessions were led by Mr. Roberts, Laurel Krzeminski, Granite’s Chief Financial Officer, and Ms. Desai, on behalf of Granite, and by Messrs. Caliel and Anderson and other members of Layne management, on behalf of Layne. The diligence sessions included specific discussions with respect to financial, operational, human resource, insurance, tax and legal matters. During the diligence sessions, Granite management also provided Granite’s preliminary fourth fiscal quarter financial results to Layne management.

On January 16, 2018, Mr. Caliel and Mr. Roberts provided one another with feedback from the recent diligence session. During this discussion, Mr. Caliel reiterated to Mr. Roberts the request that legacy Layne stockholders have representation on the Granite Board given their familiarity with Layne’s business.

In addition, from January 16, 2018 through January 18, 2018, Layne’s advisors, including Deloitte, conducted diligence review in the San Francisco office of PricewaterhouseCoopers LLP, Granite’s independent registered public accounting firm. On January 17, 2018, members of Layne management, together with its outside legal advisors, conducted legal diligence sessions with Richard Watts, Granite’s Senior Vice President, General Counsel and Secretary.

On January 19, 2018, the Layne Special Committee held a special meeting at which members of Layne management and representatives of Greentech, Latham & Watkins, Stinson and Deloitte, Layne’s external transaction advisor with respect to reverse due diligence matters, were also present. During this meeting, Messrs. Caliel, Anderson and Crooke and representatives of Layne’s outside advisors provided a preliminary summary of Layne’s reverse due diligence on Granite to the Layne Special Committee, including an analysis of legal, tax and accounting matters. In addition, representatives of Greentech provided updates with respect to valuation information and trading history, as well as an analysis regarding each company’s financial performance.

On January 23, 2018, Jones Day delivered to Latham & Watkins an initial draft of the merger agreement. The draft merger agreement, among other things, (a) provided that the obligations of Granite and Layne to consummate the Merger would be conditioned on, among other things, the approval of the Merger by the affirmative vote of a majority of the outstanding shares of Layne Common Stock entitled to vote at a special meeting of Layne stockholders; (b) provided for a then-undetermined collar on the exchange ratio for the all-stock merger consideration; (c) included representations and warranties by each party; (d) included restrictions on each party’s business during the period between execution of the merger agreement and closing of the Merger (the “interim period”); (e) included restrictions on the ability of the Layne Board to make an adverse recommendation change, other than in response to an intervening event and in accordance with certain specified requirements; (f) restricted Layne’s ability to pursue an alternative offer, unless such offer represented a superior offer in accordance with certain specified requirements; (g) provided for a termination fee equal to approximately 4.0% of the aggregate equity value on a fully diluted basis of Layne (taking into account the 8.0% Convertible Notes) that would be payable by Layne to Granite under certain specified circumstances; and (h) provided that, even if no other alternative proposal by a third party were made, Layne would be required to reimburse Granite for all of its out-of-pocket expenses in the event Layne stockholders did not approve the Proposed Transaction. While the draft merger agreement contemplated that the parties intended that the Proposed Transaction qualify as a “reorganization” within the meaning of Section 368(a) of the Code, it did not contemplate that tax opinions to that effect would be a condition to closing the transaction.

Additionally, the initial draft merger agreement contemplated that, concurrently with the execution of the merger agreement, Granite would enter into agreements with the Voting Stockholders, which agreements would provide that the Voting Stockholders would vote their shares of Layne Common Stock in favor of adoption of the proposed merger agreement.

- 71 -

On January 24, 2018, the Layne Board held a special meeting at which members of Layne management and representatives of Greentech, Latham & Watkins, Stinson and Deloitte were also present. During this meeting, representatives of Latham & Watkins reviewed the directors’ fiduciary duties in considering the Proposed Transaction. In addition, Mr. Caliel and Layne’s outside advisors provided the Layne Board with an updated analysis of due diligence matters related to the Proposed Transaction, including a summary of reverse due diligence conducted with respect to Granite’s business.

On January 30, 2018, the Layne Special Committee held a special meeting at which members of Layne management and representatives of Greentech and Latham & Watkins were also present. During this meeting, Mr. Caliel provided a status update with respect to negotiations with Granite and representatives of Latham & Watkins reviewed with the Layne Special Committee certain provisions of the initial draft merger agreement. On February 1, 2018, Mr. Roberts, on behalf of Granite, sent Messrs. Caliel and Brown a letter reaffirming Granite’s proposed $17.00 per share price valuation with a symmetrical 5.0% collar based on Granite’s 10-day volume weighted average price as of that date, meaning that the collar would have a Granite Common Stock floor price of $63.88 and a Granite Common Stock ceiling price of $70.60 (the “February 2018 Proposal”). Also on February 1, 2018, Granite management provided Layne management with updated guidance with respect to Granite’s fiscal year ending December 31, 2018.

On February 2, 2018, the Layne Special Committee held a special meeting at which members of Layne management and representatives of Greentech and Deloitte were also present. During this meeting, Mr. Caliel provided an overview of the February 2018 Proposal and the status of Layne’s reverse due diligence. Mr. Crooke and representatives of Greentech and Deloitte provided an overview of certain diligence matters related to Granite’s business.

Later on February 2, 2018, Latham & Watkins delivered to Jones Day a revised draft of the merger agreement. The revised draft merger agreement, among other things, (a) provided that delivery of tax opinions by each party’s respective counsel regarding the qualification of the merger as a “reorganization” within the meaning of Section 368(a) of the Code would be a condition to closing the Merger; (b) contemplated that Granite would provide more detailed representations and warranties regarding Granite and its businesses, together with interim operating covenants restricting certain actions by Granite during the interim period; (c) limited the termination fee payable by Layne to Granite under certain circumstances to $10.0 million; (d) provided that, if Granite were to enter into a change-in-control transaction during the interim period, Layne could terminate the transaction and receive a reverse termination fee of $10.0 million; (e) revised the conditions under which Layne would be permitted to consider an alternative proposal and the circumstances under which an alternative proposal would be deemed a superior proposal; (f) reduced certain restrictions on the conduct of Layne’s business during the interim period; and (g) eliminated any requirement that Layne reimburse Granite for its expenses in connection with the rejection by Layne stockholders of the proposed transaction absent the existence of an alternative transaction.

From February 2, 2018 through and including February 13, 2018, Granite, Layne, and their respective legal counsel exchanged drafts of, and negotiated the terms of, the merger agreement and related transaction documents.

On February 3, 2018, representatives of Perella Weinberg had a discussion with representatives of Greentech regarding the parameters of the collar on the exchange ratio in the February 2018 Proposal and the impact of the significant U.S. stock market volatility, which had commenced on February 1, 2018, on the proposed transaction.

Later on February 3, 2018, the Layne Board held an in-person meeting in Houston, Texas at which representatives of Greentech, Latham & Watkins and Deloitte were also present, either in person or telephonically. During this meeting, Mr. Caliel reviewed the February 2018 Proposal with the Layne Board. Mr. Anderson reviewed Layne’s preliminary fourth fiscal quarter outlook and discussed the status of Layne’s refinancing of Convertible Notes, which had been postponed pending further negotiations with Granite regarding

- 72 -

the Proposed Transaction, with the Layne Board. Representatives of Deloitte also provided the Layne Board with an in-depth analysis of reverse due diligence conducted on Granite’s business, including an analysis of Granite’s operational and financial performance. Representatives of Greentech provided a preliminary analysis of the February 2018 Proposal, including an analysis of potential synergies, precedent and peer merger and acquisition transactions, trading histories of both Layne and Granite, relative valuations and combined company financial projections (provided by Layne’s management) and a review of various collar parameters. Representatives of Latham & Watkins reviewed the directors’ fiduciary duties in considering the Proposed Transaction with Granite, reviewed the latest draft of the merger agreement with the Layne Board and provided a summary of the merger agreement to the Layne Board. The Layne Board authorized Layne management to continue to work with the Layne Special Committee to evaluate the Proposed Transaction and indicated support for an all-stock transaction based on an implied value of $17.00 per Layne share, subject to a collar if deemed appropriate by the Layne Special Committee.

Following that meeting, Mr. Caliel telephoned Mr. Roberts and proposed that Granite acquire all outstanding shares of Layne Common Stock at an implied value of $17.00 per share, subject to a symmetrical 10% collar given recent stock market volatility.

In the afternoon of February 4, 2018, Jones Day delivered to Latham & Watkins an initial draft of the Voting Agreement.

In the afternoon of February 5, 2018, Mr. Roberts telephoned Mr. Caliel to discuss the proposed exchange ratio and related collar. During that call, Messrs. Roberts and Caliel discussed the recent volatility in the U.S. stock markets generally, including the recent decline in the price of both Granite Common Stock and Layne Common Stock that continued throughout that day. Messrs. Roberts and Caliel agreed that, while they would direct their respective teams to continue to work toward signing a definitive agreement the following week, they would suspend discussions regarding the exchange ratio and collar until the volatility in stock prices subsided.

In the afternoon of February 5, 2018, the Granite Board met in Nashville, Tennessee. Senior management of Granite and representatives of Perella Weinberg and Jones Day also participated in the meeting. At that meeting, a representative from Jones Day reviewed the Granite Board’s fiduciary duties under Delaware law in a transaction such as the one contemplated with Layne and provided the Granite Board with a summary of the terms of the current draft of the merger agreement and the most significant open legal issues with respect to the draft merger agreement, which, in addition to the collar, included (a) the delivery of tax opinions as a condition to closing the Merger; (b) that Layne was requesting from Granite a reverse termination fee of $10.0 million if Granite were to enter into a change-in-control transaction during the interim period; (c) the dollar amount of the termination fee that would be payable by Layne to Granite and the circumstances when such a fee would be payable and (d) the absence of any requirement that Layne reimburse Granite for its expenses in connection with the rejection by Layne stockholders of the proposed transaction absent the existence of an alternative transaction.

On February 6, 2018, the Granite Board continued the meeting initiated on the preceding day. Senior management of Granite and representatives from Perella Weinberg also participated in the meeting. At that meeting, representatives from Perella Weinberg presented a summary of the principal financial terms of the proposed transaction, and members of Granite senior management reviewed with the Granite Board the status of due diligence findings to date. The Granite Board also discussed the recent volatility in the U.S. stock markets generally, including the recent decline in the price of both Granite Common Stock and Layne Common Stock, and the fact that that volatility was complicating negotiations as to a mutually acceptable exchange ratio and collar.

On February 7, 2018, Jones Day delivered to Latham & Watkins a revised draft of the merger agreement. Among other things, the revised draft merger agreement, (a) deleted the delivery of tax opinions as a closing condition; (b) revised interim operating covenants restricting certain actions by Layne between signing and consummation of the Merger; (c) revised the termination fee payable by Layne to Granite under certain circumstances to approximately $17.5 million; (d) deleted Layne’s right to terminate the merger agreement and

- 73 -

receive a reverse termination fee if Granite were to enter into a change-in-control transaction during the interim period; and (e) reinserted a requirement that Layne reimburse Granite for its expenses in connection with the rejection by Layne stockholders of the proposed transaction absent the existence of an alternative transaction but capped such reimbursement at $3.0 million. Also on February 7, 2018 representatives of Latham & Watkins sent a revised Voting Agreement to Jones Day.

On February 8, 2018, Mr. Roberts and Ms. Desai telephoned Messrs. Caliel and Anderson and informed them that, in light of its ongoing due diligence and given the significant stock market volatility in early February 2018, Granite was now offering to acquire all outstanding shares of Layne Common Stock at a price of $16.50 per share, supported by a collar to be determined.

Later on February 8, 2018, the Layne Board held a special telephonic meeting at which members of Layne management and representatives of Greentech and Latham & Watkins were also present. During this meeting, Mr. Caliel provided the Layne Board with an update with respect to continued negotiations related to the Proposed Transaction, including the proposed reduction in the implied value per share in exchange for a collar to be negotiated. Representatives of Greentech provided a financial analysis with respect to various combinations of implied value per share and collar parameters. The Layne Board recommended that Layne management continue to pursue the Proposed Transaction based on an implied value of $17.00 per share. The Layne Board further determined that, given the decline in the market, including the change in the share price of Granite Common Stock, setting an exchange ratio without a collar would be more favorable to Layne stockholders as recovery in the overall markets and in the share price of Granite Common Stock would directly benefit Layne stockholders. In arriving at this determination, the Layne Board also analyzed precedent transactions with Layne management and representatives of Greentech and observed that a substantial majority of all-stock transactions did not include a collar mechanism.

Throughout February 9, 2018, Mr. Roberts and Mr. Caliel had several telephone calls to discuss the Proposed Transaction and ultimately agreed to an exchange ratio of 0.27 based on the volume-weighted average prices for Granite Common Stock and Layne Common Stock over the preceding 10-trading day and 90-trading day periods. The 0.27 exchange ratio represented, as of February 9, 2018, an implied value per Layne share of approximately $17.00, or a premium of 33.0%, based on the 10-day and 90-day volume-weighted average prices for Granite Common Stock and Layne Common Stock.

In the afternoon of February 9, 2018, Granite’s and Layne’s respective legal counsel had a telephone conference to discuss and negotiate the terms of the merger agreement. Later that afternoon, Granite, Layne and their respective legal and financial advisors had a telephone call to discuss the status and timing of the proposed transaction and each party’s anticipated fourth fiscal quarter and anticipated fiscal year-end financial performance.

Also on February 9, 2018, Latham & Watkins delivered to Jones Day a revised draft of the merger agreement. The revised draft merger agreement, among other things, (a) provided that delivery of tax opinions by each party’s respective counsel regarding the qualification of the merger as a “reorganization” within the meaning of Section 368(a) of the Code would be a condition to closing the Merger; (b) contemplated that Granite would provide more detailed representations and warranties regarding Granite and its businesses, together with interim operating covenants restricting certain actions by Granite during the interim period; (c) limited the termination fee payable by Layne to Granite under certain circumstances to $15.0 million; (d) provided that if Granite were to enter into a change-in-control transaction during the interim period, Layne could terminate the transaction and receive a reverse termination fee of $15.0 million; (e) reduced certain restrictions on the conduct of Layne’s business during the interim period; and (f) eliminated any requirement that Layne reimburse Granite for its expenses in connection with the rejection by Layne stockholders of the proposed transaction absent the existence of an alternative transaction.

Later on February 9, 2018, the Layne Special Committee held a meeting at which members of Layne management and representatives of Greentech and Latham & Watkins were also present. During this meeting, Mr. Caliel relayed his discussion with Mr. Roberts earlier that day to the Layne Special Committee, including the

- 74 -

0.27 exchange ratio. Representatives of Greentech also provided an analysis with respect to the 0.27 exchange ratio, each company’s recent and historical trading history, as well as a discussion of peer transactions and exchange ratios. Mr. Anderson and representatives of Greentech also provided the Layne Special Committee with an overview of each company’s anticipated fourth quarter performance. The Layne Special Committee indicated its support for the 0.27 exchange ratio and recommended that Layne management continue to finalize the terms of the merger agreement.

Over the course of February 10, 2018 and February 11, 2018, representatives of Latham & Watkins and Jones Day participated in various negotiations related to the terms of the merger agreement and the voting agreement and related diligence matters.

In the morning of February 11, 2018, Granite, Layne and their respective financial and legal advisors had a telephone call to negotiate the remaining open items to the merger agreement. Specifically, the parties and their advisors negotiated provisions relating to (a) each party obtaining, as a condition to the Merger, a tax opinion regarding the tax treatment of the Merger; (b) the size of the termination fee; (c) whether Layne would be required to reimburse Granite for all of its out-of-pocket expenses in the event Layne stockholders did not approve the proposed transaction; and (d) the restrictive covenants that would limit the flexibility of the Layne Board and Layne management to operate Layne’s business during the interim period.

Later on February 11, 2018, the Layne Board held a meeting at which members of Layne management and representatives of Greentech and Latham & Watkins were also present. During this meeting, Mr. Caliel provided the Layne Board with an overview of the Proposed Transaction, including the negotiations resulting in the 0.27 exchange ratio. Mr. Anderson also provided the Layne Board with an overview of each company’s anticipated fourth fiscal quarter financial performance. Representatives of Greentech also provided updates on various matters relating to the Proposed Transaction, including the implied premium as originally proposed by Granite, the ensuing discussions between parties regarding the determination of the exchange ratio and Greentech’s financial perspectives regarding the proposed 0.27 exchange ratio. Representatives of Greentech also provided a preliminary valuation analysis of the transaction. Representatives of Greentech noted that its preliminary analysis was subject to continuing due diligence, including on Granite’s fiscal fourth quarter results, the share price movements of the two companies and general stock market conditions. Mr. Caliel discussed with the Layne Board the primary unresolved transaction terms and the proposed communications plan in the event the parties entered into a definitive merger agreement. Representatives of Latham & Watkins reviewed the directors’ duties in considering the Proposed Transaction and the principal terms of the merger agreement. After discussion, the Layne Board determined to convene once the terms of the merger agreement were substantially final.

On February 12, 2018, Mr. Caliel telephoned Mr. Roberts to discuss the open issues in the merger agreement and to also review the prior request that the Granite Board appoint one of Layne’s directors to the Granite Board effective as of the closing of the Proposed Transaction.

Later on February 12, 2018, members of Granite management, together with Granite’s outside advisors, participated in a diligence call with members of Layne management, together with Layne’s outside advisors, updating each company’s anticipated fourth fiscal quarter financial performance.

Throughout February 12 and February 13, 2018, Granite, Layne and their respective financial and legal advisors continued to negotiate the merger agreement, and Jones Day and Latham & Watkins finalized the other related documents, including the Voting Agreements. As a result of those negotiations, the parties agreed that the merger agreement would provide, among other things, (a) the delivery of tax opinions as a condition to closing the Merger; (b) a termination fee of $16.0 million payable by Layne to Granite, under certain circumstances; (c) no requirement that Layne reimburse Granite for its out-of-pocket expenses in the event Layne stockholders did not approve the proposed transaction, absent the existence of an alternative transaction and (d) that effective as of the Effective Time, the Granite Board would be expanded and one current director of Layne would be appointed to the Granite Board.

- 75 -

Following the close of trading on the NYSE on the afternoon of February 13, 2018, the Granite Board held a telephonic meeting. The purpose of the meeting was for the Granite Board to consider and vote upon approval of the proposed final draft merger agreement and related draft voting agreement. Senior management of Granite and representatives from Perella Weinberg and Jones Day also participated in the meeting. Mr. Roberts discussed with the Granite Board the fact that Layne had requested that, as part of the transaction, Granite agree to appoint one Layne director to the Granite Board effective as of the Effective Time. Mr. Roberts noted that that was the only remaining open issue. Mr. Roberts also noted that in addition to potentially aiding in the integration of Layne post-Merger, several of Layne’s directors may possess the characteristics, experience and expertise that are often sought by the Granite Board with respect to identifying potential directors. After deliberations, the Granite Board agreed to appoint a Layne director of its choice to the Granite Board effective as of the Effective Time. Following such discussions, representatives from Perella Weinberg presented a summary of the principal financial terms of the proposed transaction, and representatives from Jones Day reviewed with the Granite Board the principal legal terms of the proposed final draft merger agreement and draft voting agreement.

Following review and discussion among the members of the Granite Board, the Granite Board unanimously (a) determined that the Merger Agreement and the transactions contemplated thereby were advisable, fair and in the best interests of Granite and its stockholders and (b) approved the Merger Agreement, the Merger and all other actions and transactions contemplated by the Merger Agreement. The Granite Board also unanimously approved the Voting Agreements.

Later on February 13, 2018, the Layne Board held a special telephonic meeting at which members of Layne management and representatives of Greentech and Latham & Watkins were also present. During this meeting, representatives of Latham & Watkins reviewed the principal legal terms of the merger agreement, focusing primarily on the updates from the draft reviewed with the Layne Board on February 11, 2018. These updates included (a) providing that, effective as of the Effective Time, the Granite Board would be expanded and one current director of Layne would be appointed to the Granite Board; (b) removing the reverse termination fee payable by Granite if Granite were to enter into a change-in-control transaction during the interim period; (c) finalizing the termination fee payable to Granite under certain specified circumstances and (d) finalizing the exceptions to the restrictions on the conduct of Layne’s business during the interim period, including the limitation on equity, asset and property acquisitions, the restriction on Layne’s ability to sell assets and the prohibition on Layne’s ability to make additional equity grants during the interim period.

Representatives of Greentech updated the Layne Board as to certain information previously provided to the Layne Board regarding its Exchange Ratio analysis, including a summary of each party’s trading history since February 9, 2018 and confirming a 0.27 exchange ratio, when applied to the 90-day volume-weighted average price as of February 12, 2018, was consistent with a $17.00 value for Layne stockholders. At the request of the Layne Board, Greentech reviewed with the Layne Board its financial analysis of the exchange ratio and rendered an oral opinion, confirmed by delivery of a written opinion dated February 13, 2018, to the Layne Board to the effect that, as of such date and based on and subject to various assumptions made as set forth in its written opinion, procedures followed, matters considered and limitations and qualifications on the review undertaken, the 0.27 exchange ratio was fair, from a financial point of view, to the holders of Layne Common Stock (excluding shares owned by Layne as treasury stock, or shares that are owned directly or indirectly by Granite, Merger Sub or any wholly owned subsidiary of Layne, Granite or Merger Sub). Representatives of Latham & Watkins then reviewed with the Layne Board the proposed resolutions to be considered by the Layne Board. After discussion, the Layne Board unanimously (a) determined that the Merger Agreement and the merger were in the best interests of Layne and its stockholders, (b) declared advisable and approved the Merger Agreement and (c) resolved to recommend that Layne stockholders adopt the Merger Agreement.

Later that evening, on February 13, 2018, the Merger Agreement and the Voting Agreements were executed and delivered. The signing of the Merger Agreement was publicly announced on February 14, 2018, prior to the opening of trading on Nasdaq and the NYSE.

Effects of the Merger

Upon completion of the Merger, Merger Sub, a wholly owned subsidiary of Granite, will merge with and into Layne. Layne will be the Surviving Corporation and will become a direct wholly owned subsidiary of Granite.

Treatment of Layne Common Stock

At the Effective Time, each share of Layne Common Stock issued and outstanding immediately prior to the Effective Time (other than treasury shares of Layne and any shares of Layne Common Stock owned, directly or indirectly, by a wholly owned subsidiary of Layne, Granite or Merger Sub) will be cancelled and converted automatically into the right to receive, in accordance with the terms of the Merger Agreement, 0.27 shares of Granite Common Stock.

Treatment of Layne Stock Options

Treatment of Layne RSUs

Treatment of Layne PSUs

Each Layne PSU that is outstanding and unvested immediately prior to the Effective Time shall, immediately prior to the Effective Time, vest, and the underlying number of shares of Layne Common Stock earned will be determined based on the maximum level of achievement of the applicable performance goals.

Other Effects

The rights pertaining to Granite Common Stock will be different from the rights pertaining to Layne Common Stock, because the Granite Charter and the Granite Bylaws in effect immediately after the completion of the Merger will be different from the Layne Charter and the Layne Bylaws, respectively. A further description

- 77 -

of the rights pertaining to Granite Common Stock and the Granite Charter and Granite Bylaws is set forth under “Comparison of Rights of Holders of Granite Common Stock and Layne Common Stock” beginning on page 134 of this proxy statement/prospectus.

Layne Board Recommendation and Its Reasons for the Merger

At a meeting held on February 13, 2018, the Layne Board, after careful review and consideration, unanimously approved the Merger Agreement and determined that the Merger Agreement and the Merger were in the best interests of Layne and its stockholders. The Layne Board unanimously recommends that Layne stockholders vote (a) “FOR” the adoption of the Merger Agreement, (b) “FOR” the compensation proposal and (c) “FOR” the adjournment proposal.

In evaluating the Merger, the Layne Board consulted with Layne’s management, as well as Layne’s legal and financial advisors, and, in reaching its conclusion, considered the following primary factors:

•

The Layne Board’s knowledge of Layne’s business, operations, financial condition, earnings and prospects. Specifically, the Layne Board recognized the significant capital constraints Layne faced in continuing to develop its business, including its near-term debt maturities, lack of recent and projected free cash flow and the challenges and execution risk of operating three distinct businesses that have limited operating synergies with one another and require significant capital investment to meaningfully grow. In particular, the Layne Board recognized that significant capital investment would be required to develop the relatively new water midstream business. The Layne Board also considered the market risk associated with any delayed recovery in the minerals sector.

•

The Layne Board’s knowledge of Granite’s business, operations, financial condition, earnings and prospects, taking into account the results of its due diligence review of Granite by Layne and its advisors.

•

The Exchange Ratio of 0.270 shares of Granite Common Stock for each share of Layne Common Stock, equating to a $17.00 per share valuation of Layne Common Stock based upon the volume-weighted average prices for Granite and Layne shares over the 90 trading days prior to the execution of the Merger Agreement, which was a significant improvement over Granite’s initial offer, which was $11.75 per share of Layne Common Stock. In response to recent market volatility, the Layne Board also considered the volume-weighted average prices for Granite and Layne shares over the 10-trading days prior to the execution of the Merger Agreement in evaluating the Exchange Ratio.

•

The Merger Consideration, with an implied value of $17.00 per share of Layne Common Stock, based upon the volume-weighted average prices for Granite and Layne shares over the 10- and 90-trading day periods prior to February 13, 2018, represented a premium of 35% to the closing price of Layne Common Stock on that date, which was a significant increase from Granite’s initial offer of $11.75 per share of Layne Common Stock (which represented a 7.2% premium to the closing price of Layne Common Stock on the day prior to the making of that offer).

•

Based on the implied value of the Merger Consideration as of February 13, 2018, Layne shareholders will own approximately 16% of the combined company on a fully diluted, pro forma basis, including the assumed conversion of the 8.0% Convertible Notes.

•

Layne had explored a variety of strategic alternatives focusing on growing its business and developing value for its stockholders. These alternatives included raising growth capital from new and existing sources of capital and evaluating potential acquisition, sale and expansion opportunities relating to one or more divisions of Layne’s business, as well as evaluating Layne’s prospects on a standalone basis. For additional discussion of the strategic alternatives evaluated by Layne, see “—Background of the Merger.”

•

As part of evaluating Layne’s prospects on a standalone basis, the Layne Board acknowledged the significant capital constraints Layne faced in continuing to develop its business, including

- 78 -

the upcoming maturities of the Convertible Notes and the refinancing proposals received, as well as the anticipated capital requirements that would be necessary to meaningfully expand each of Layne’s businesses.

•

The Layne Board considered feedback from potential strategic counterparties and financial sponsors received by Layne management since early 2016, including discussions with at least nine potential strategic and financial counterparties that either expressed no interest in pursuing a strategic transaction with Layne or failed to adequately value Layne’s businesses.

•

The Layne Board and Layne management determined that Granite had a strategic vision for the combined company, as reflected by Granite’s continuing interest in Layne and the significant amount of due diligence completed over an extended period of time from the December 2016 Proposal through the announcement of the Merger in February 2018. In particular, Granite had expressed publicly on its earnings calls and in other contexts its interest in expanding into the water infrastructure business given that business’s strong dynamics and strategic fit with Granite’s current end-market focus. Layne management believed that Granite’s strategic vision for Layne’s business, coupled with Granite’s superior access to capital and lower cost of capital, history of successful acquisition integration and greater market capitalization and research analyst coverage, would provide enhanced value for Layne’s stockholders.

•

Following discussion with Layne’s management and financial advisors, the Layne Board concluded that the transaction with Granite offered a more favorable long-term opportunity for Layne’s stockholders than the various strategic alternatives considered by Layne’s management over the course of its strategic review process. The transaction with Granite also provided the greatest likelihood relative to the other opportunities that had been explored since 2016 that a transaction would be completed on terms favorable to Layne stockholders.

•

The Layne Board’s view that the Merger provides Layne stockholders with equity ownership in a combined company with a more diversified, expanded national platform of assets that is expected to be positioned as a national leader across both the transportation and water infrastructure markets and possess a stronger financial position and superior access to capital. The Layne Board also expected that the combined company would have better access to capital at a lower cost, allowing the combined company to better capitalize on attractive opportunities and macro-dynamics in the water industry.

•

The Layne Board’s view that Layne stockholders would benefit from a combined company that expected annual run-rate synergies of approximately $20 million by the third year following closing of the Merger.

•

The financial analyses and presentations of Greentech to the Layne Board with respect to Granite and Layne, and Layne’s related written opinion, dated as of February 13, 2017, to the effect that, as of the date of the opinion and subject to the various assumptions made, procedures followed, factors considered, and limitations of the review undertaken, qualifications contained and other matters set forth therein, the Exchange Ratio of 0.270 was fair, from a financial point of view, to the holders of Layne Common Stock (excluding shares owned by Layne as treasury stock, or shares that are owned directly or indirectly by Granite, Merger Sub or any wholly-owned subsidiary of Layne, Granite or Merger Sub). See “—Opinion of Financial Advisor to Layne” and Annex C to this proxy statement/prospectus, which set forth various assumptions made, procedures followed, factors considered and limitations of the review undertaken, qualifications contained and other matters in connection with the opinion. The full text of the written opinion of Greentech is attached as Annex C and is incorporated by reference into this section of the proxy statement/prospectus.

•

The Layne Board’s view that Granite and Layne share similar cultures and core values focused on ethics, safety, sustainability and commitment to community, integrity, accountability and excellence.

•

The Layne Board retained financial and legal advisors with knowledge and experience with respect to public merger and acquisition transactions, Granite’s and Layne’s industry generally and Layne

- 79 -

particularly, as well as substantial experience advising other companies with respect to transactions similar to the Merger.

•

The Layne Board’s review, in consultation with Layne’s legal advisors, of the structure of the Merger and the financial and other terms and conditions of the Merger Agreement, including the Merger Consideration, the Layne Board’s expectation that the Merger would qualify as a “reorganization” within the meaning of Section 368(a) of the Code and the Layne Board’s view of the likelihood of completing the Merger on the anticipated schedule.

•

The terms of the Merger Agreement, principally:

•

the provisions allowing the Layne Board to withdraw or change its recommendation of or to terminate the Merger Agreement, subject to the payment of a specified termination fee upon termination under certain circumstances, in the event of a superior proposal, or to change its recommendation in the event of certain intervening events, if the Layne Board makes a good faith determination that the failure to change its recommendation or terminate the Merger Agreement would be inconsistent with its fiduciary duties under applicable law;

•

the fact that the provisions do not provide for a vote of Granite’s stockholders to approve the Merger; and

•

the fact that the consummation of the Merger is not conditioned on financing.

•

The Layne Board’s understanding of, and management’s review of, overall market conditions, including the current and historical trading prices for Granite Common Stock and Layne Common Stock, and the Layne Board’s view that, in light of these factors, the timing of the potential transaction was favorable to Layne.

•

Layne management’s recommendation in favor of the Merger.

The Layne Board also considered potential risks and potentially negative factors concerning the Merger in connection with its deliberations of the proposed transaction, including:

•

The fact that the Exchange Ratio is fixed and therefore the value of the consideration payable to Layne stockholders will decrease in the event that the market price of Granite Common Stock decreases prior to the closing of the Merger.

•

The possibility that the Merger may not be completed, or that completion may be unduly delayed, for reasons beyond the control of Granite or Layne, which could result in significant costs and disruption to Layne’s normal business.

•

Certain terms of the Merger Agreement, principally:

•

restrictions on the ability of Layne to solicit offers for alternative proposals or to engage in discussions regarding such proposals, subject to certain exceptions including in the case of a superior proposal, which could have the effect of discouraging such proposals from being made or pursued.

•

the termination fee of $16 million that would be payable by Layne in connection with a termination of the Merger Agreement as a result of, among other circumstances, a superior proposal for Layne, which, although within the range of such fees normally seen in similar transactions, could have the effect of discouraging an alternative proposal for Layne; and

•

restrictions on the conduct of Layne business during the period between the signing of the Merger Agreement and completion of the Merger, including restrictions on Layne’s ability to (a) issue, sell, dispose of or pledge its equity securities, (b) acquire equity securities, assets or properties of any third party worth in excess of $9 million in the aggregate and (c) sell, pledge or dispose of properties, rights or assets to a third party (other than inventory sales in the ordinary course of Layne’s business). For additional discussion on the restrictions on Layne’s business between the

- 80 -

signing of the Merger Agreement and completion of the Merger, see “The Merger Agreement—Conduct of Business Pending Merger” beginning on page 118 of this proxy statement/prospectus.

•

The fact that Layne’s stockholders will be foregoing the potential benefits, if any, that could be realized by remaining as stockholders of Layne as a standalone entity, including the growth of Layne’s Water Resources division and particularly Layne’s relatively new water midstream business, in the event Layne could obtain sufficient capital on favorable terms to support such growth or the anticipated growth in Layne’s business arising from a recovery in the minerals market, if such recovery were to occur on a timely basis.

•

The potential for diversion of Layne management and employee attention and for increased employee attrition during the period prior to completion of the Merger, and the potential effect of the Merger on Layne’s business and relations with customers, suppliers and regulators.

•

The substantial costs to be incurred in connection with the Merger, including the costs of integrating the businesses of Granite and Layne and the transaction expenses arising from the Merger.

•

The risks of the type and nature described under “Risk Factors” beginning on page 22, and the matters described under “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 31.

The foregoing discussion is not intended to be exhaustive, but is intended to address the material information and principal factors considered by the Layne Board in considering the Merger. In view of the number and variety of factors and the amount of information considered, the Layne Board did not find it practicable to, and did not make specific assessments of, quantify or otherwise assign relative weights to, the specific factors considered in reaching its determination. In addition, the Layne Board did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to its ultimate determination, and individual members of the Layne Board may have given different weights to different factors.

The Layne Board made its recommendation based on the totality of information presented to, and the investigation conducted by, the Layne Board. It should be noted that certain statements and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 31 of this proxy statement/prospectus.

Opinion of Financial Advisor to Layne

Opinion of Greentech Capital Advisors Securities, LLC

Layne retained Greentech Capital Advisors Securities, LLC (“Greentech”) to act as Layne’s financial advisor in connection with the Merger. Greentech is an internationally recognized investment banking firm that is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, private placements and valuations for corporate and other purposes. Layne selected Greentech to act as Layne’s financial advisor in connection with the Merger on the basis of Greentech’s experience in transactions similar to the Merger, its reputation in the investment community and its familiarity with Layne and its business.

- 81 -

The full text of Greentech’s written opinion to the Layne Board, which describes, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken, qualifications contained and other matters set forth therein, is attached to this proxy statement/prospectus as Annex C and is incorporated by reference herein in its entirety. The following summary of Greentech’s opinion is qualified in its entirety by reference to the full text of the opinion. Greentech delivered its opinion to the Layne Board for the benefit and use of the Layne Board (in its capacity as such) in connection with and for purposes of its evaluation of the Merger. Greentech’s opinion does not address any other aspect of the Merger other than the fairness of the Exchange Ratio, from a financial point of view, to the holders of Layne Common Stock (excluding shares owned by Layne as treasury stock, or shares that are owned directly or indirectly by Granite, Merger Sub or any wholly-owned subsidiary of Layne, Granite or Merger Sub), and no opinion or view was expressed as to the relative merits of the Merger in comparison to other strategies or transactions that might be available to Layne, or in which Layne might engage, or as to the underlying business decision of Layne to proceed with or effect the Merger. Greentech’s opinion does not address any other aspect of the Merger and does not constitute a recommendation to the Layne Board as to how the Layne Board should vote on the Merger or to any stockholder of Layne as to how any such stockholder should vote at any stockholders’ meeting at which the Merger is considered, or whether or not any stockholder of Layne should enter into a voting, shareholders’, or affiliates’ agreement with respect to the Merger or exercise any dissenter’s or appraisal rights that may be applicable to such stockholder.

In connection with rendering its opinion, Greentech, among other things:

•

discussed the Merger and related matters with Layne’s counsel and reviewed the financial terms and conditions of the Merger as set forth in a draft of the Merger Agreement, dated February 13, 2018, such draft being the last draft of the Merger Agreement made available to Greentech;

In rendering its opinion, Greentech, with Layne’s consent, relied upon and assumed, without independent verification, the accuracy and completeness of all of the financial and other information that was made available, supplied or otherwise communicated to Greentech by or on behalf of Layne or Granite, or that was otherwise reviewed by Greentech, including, without limitation, publicly available information, and does not assume any responsibility for independently verifying any of such information. Greentech relied on such information being complete and correct in all material respects and further relied upon the assurances of the managements of Layne and Granite, as applicable, that, to their knowledge, such information does not contain any material omissions or misstatements of material fact. With respect to the Forecasts supplied to Greentech by Layne and Granite, Greentech assumed, at the direction of Layne, that they were reasonably prepared on the basis reflecting the best currently available estimates and good faith judgments of the management of Layne and the management of Granite, respectively, as to the future operating and financial performance of Layne and Granite, respectively, and that they provided a reasonable basis upon which Greentech could form its opinion. The Forecasts were not prepared with the expectation of public disclosure and they are based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in the Forecasts.

Greentech also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of Layne or Granite since the date of the last financial statements and other financial information of Layne or Granite, respectively, made available to or reviewed by Greentech. Greentech did not make or obtain any independent evaluation, appraisal or physical inspection of Layne’s or Granite’s assets or liabilities, respectively, nor was Greentech furnished with any such evaluation or appraisal. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, Greentech assumes no responsibility for their accuracy.

Greentech assumed, with Layne’s consent, that there were no factors that would delay or subject to any adverse conditions any necessary regulatory or governmental approval and that all conditions to the Merger would be satisfied without any material waiver, amendment or delay. In addition, Greentech assumed that the definitive Merger Agreement would not differ materially from the draft Greentech had reviewed. Greentech also assumed that the Merger will be consummated substantially on the terms and conditions described in the Merger Agreement, without any adjustment to the Exchange Ratio or waiver of material terms or conditions by any party thereto, and that obtaining any necessary regulatory approvals or satisfying any other conditions for consummation of the Merger would not have an adverse effect on Layne, Granite, Merger Sub or the Merger. Greentech assumed that the Merger would be consummated in a manner that complies with the applicable provisions of the Securities Act, the Exchange Act and all other applicable federal and state statutes, rules and regulations. Greentech further assumed that Layne had relied upon the advice of its counsel, independent accountants and other advisors (other than Greentech) as to all legal, financial reporting, tax, accounting and regulatory matters with respect to Layne, Granite, Merger Sub, the Merger and the Merger Agreement.

Greentech’s opinion is limited to whether the Exchange Ratio, from a financial point of view, was fair to the holders of Layne Common Stock (excluding shares owned by Layne as treasury stock, or shares that are owned directly or indirectly by Granite, Merger Sub or any wholly-owned subsidiary of Layne, Granite or Merger Sub), and did not address any other terms, aspects or implications of the transactions contemplated by the Merger Agreement, including, without limitation, the form or structure of the Merger, any consequences of the Merger on Layne, Granite or their respective stockholders, creditors or otherwise, or any terms, aspects or implications of any voting, support, stockholder or other agreements, arrangements or understandings contemplated or entered into in connection with the transactions contemplated by the Merger Agreement or otherwise. Greentech’s opinion also did not consider, address or include: (a) the legal, tax or accounting consequences of the Merger on

- 83 -

Layne, Granite or their respective security holders; (b) the fairness of the amount or nature of any compensation to any of Layne’s or Granite’s officers, directors or employees, or class of such persons, relative to the compensation to the holders of Layne Common Stock, (c) the fairness of the Merger to holders of any class of securities of Layne other than the holders of Layne Common Stock (excluding shares owned by Layne as treasury stock, or shares that are owned directly or indirectly by Granite, Merger Sub or any wholly-owned subsidiary of Layne, Granite or Merger Sub), or any class of securities of any other party to any transaction contemplated by the Merger Agreement; (d) any advice or opinions provided by any other advisor to Layne or Granite; (e) the treatment of, or effect of the Merger on, any securities of Layne (including, without limitation, any Layne Stock Options, Layne RSUs and Layne PSUs or Granite other than Layne Common Stock, or the holders of any such securities; or (f) any other strategic alternatives currently (or which had been or may be) contemplated by the Layne Board or Layne. Furthermore, Greentech did not express any opinion as to the prices, trading range or volume at which Layne Common Stock or Granite Common Stock would trade following public announcement or consummation, as applicable, of the Merger.

Greentech’s opinion was necessarily based on economic, market, financial and other conditions as they existed as of the date of Greentech’s opinion, and on the information made available to Greentech by or on behalf of Layne, Granite or their respective advisors, or information otherwise reviewed by Greentech, as of the date of its opinion. Subsequent developments may affect the conclusion reached in Greentech’s opinion and Greentech does not have any obligation to update, revise or reaffirm its opinion. Greentech’s opinion is for the information of, and directed to, the Layne Board (in its capacity as such) for its information and assistance in connection with its consideration of the Merger and may not be used for any other purpose. Greentech’s opinion does not constitute a recommendation to the Layne Board as to how the Layne Board should vote on the Merger or to any stockholder of Layne as to how any such stockholder should vote at any stockholders’ meeting at which the Merger is considered, or whether or not any stockholder of Layne should enter into a voting, shareholders’, or affiliates’ agreement with respect to the Merger or exercise any dissenter’s or appraisal rights that may be applicable to such stockholder. In addition, Greentech’s opinion did not compare the relative merits of the Merger with any other alternative transactions or business strategies which may have been available to Layne and did not address the underlying business decision of the Layne Board or Layne to proceed with or effect the Merger.

Greentech did not consider any potential legislative or regulatory changes currently being considered by the United States Congress, the SEC or any other regulatory bodies, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board. Greentech’s opinion did not in any way address the solvency or financial condition of Layne, Granite or any other participant in the Merger.

The issuance of Greentech’s opinion was approved by a fairness opinion review committee of Greentech.

The following is a brief summary of the principal financial analyses performed by Greentech to arrive at its opinion. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses performed by Greentech, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses performed by Greentech. Considering the data set forth in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses performed by Greentech. Greentech reviewed with the Layne Board the assumptions on which such analyses were based and other factors. No limitations were imposed by the Layne Board with respect to the assumptions made, procedures followed, limitations of the review undertaken, qualifications contained and other matters considered by Greentech in rendering its opinion. Greentech noted that the implied offer price was $16.79 per share of Layne Common Stock based on the Exchange Ratio of 0.270 and the 10-day volume weighted average price (“VWAP”) of Granite Common Stock as of February 12, 2018, and that the implied offer price was $17.00 per share of Layne Common Stock based on the Exchange Ratio and the 90-day VWAP of Granite Common Stock as of February 12, 2018.

Discounted Cash Flow Analyses

Greentech performed separate discounted cash flow analyses of Layne and Granite to calculate ranges of implied present values of the unlevered, after-tax free cash flows that Layne and Granite were forecasted to generate from February 15, 2018 to January 31, 2022, calendarized to December 31, 2021, for Layne and February 15, 2018 to December 31, 2020 for Granite, utilizing the Layne Forecasts and the Granite Forecasts, respectively.

Layne. In performing a discounted cash flow analysis of Layne, present values (as of February 15, 2018 based on mid-year convention) of the unlevered cash flows and terminal values were calculated using a selected discount rate range of 10.3% to 12.3%. The discount rates represent a range around Layne’s weighted average cost of capital of 11.3%, derived by application of the capital asset pricing model, which takes into account certain company-specific metrics, including Layne’s target capital structure, cost of long-term debt, after-tax yield on permanent excess cash, if any, forecast tax rate and historical beta, as well as certain financial metrics for the selected companies and the United States financial markets generally. Unlevered free cash flows were calculated by taking estimated earnings and subtracting the amount of projected taxes, capital expenditures, increases in working capital and gains on sales of assets, and adding back projected depreciation and amortization. Greentech derived implied terminal values for Layne by applying perpetual growth rates of 1.5% to 2.0% to Layne’s terminal year unlevered free cash flow. The future values of all of the unlevered free cash flows for the four-year period calendarized to December 31, 2021 as described above were then discounted back to February 15, 2018 using the discount rates described above and then adjusted for Layne’s cash and debt balances as of October 31, 2017. Based on the number of shares outstanding calculated on a fully-diluted basis as of October 31, 2017, this analysis indicated an implied per share equity value reference range for Layne of $12.51 to $17.70. The implied per share equity value of Layne’s federal net operating loss carryforward balance (“NOL”) was estimated to be $0.60 per share of Layne Common Stock, calculated using a discount rate of 11.3%. After including the estimated per share value for the NOL in the upper end of the implied per share equity value reference range described above, Greentech’s analysis indicated an implied per share equity value reference range for Layne of $12.51 to $18.30.

Granite. In performing a discounted cash flow analysis of Granite, present values (as of February 15, 2018 based on mid-year convention) of the unlevered cash flows and terminal values were calculated using a selected discount rate range of 9.0% to 11.0%. Unlevered free cash flows were calculated by taking estimated earnings and subtracting the amount of projected taxes, capital expenditures, increases in working capital, gains on sales of assets and income for non-controlling interests, and adding back projected depreciation and amortization. Greentech derived implied terminal values for Granite by applying a multiple range to Granite’s terminal year Adjusted EBITDA (as defined below). Based on the Granite Forecasts, Greentech used a range of enterprise values, calculated as equity values based on closing stock prices on February 12, 2018, plus debt, preferred stock and minority interest, and less cash and cash equivalents (“EVs”), to adjusted last twelve month (“LTM”) earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”) multiples of 8.0x to 10.0x and applied such multiple range to Granite’s terminal year Adjusted EBITDA to derive implied terminal values for Granite. The future values of the unlevered free cash flows and implied terminal value for Granite were then discounted back to February 15, 2018 using the discount rates described above. The present values of all of the unlevered free cash flows were then adjusted for Granite’s cash and debt balances as of September 30, 2017. This analysis indicated an implied per share equity value reference range for Granite of $59.56 to $76.56.

Utilizing the approximate implied per share equity value reference ranges for Layne and Granite described above, Greentech calculated the following implied Exchange Ratio reference range, as compared to the Exchange Ratio:


Implied Exchange Ratio Reference Range	Exchange Ratio
0.171x – 0.307x		0.270x

Selected Publicly Traded Companies Analyses

Greentech performed separate selected publicly traded companies analyses of Layne and Granite in which Greentech reviewed and compared financial and operating data relating to Layne, Granite and the selected publicly traded companies listed below.

Layne. In performing a selected public companies analysis of Layne, Greentech reviewed publicly available financial and stock market information for Layne and the following five selected companies that Greentech viewed as generally relevant as publicly traded water-related Engineering, Procurement, and Construction companies (the “Selected Layne EPCs”):

•

Aegion Corporation

•

MasTec, Inc.

•

Primoris Services Corporation

•

Select Energy Services, Inc.

•

Stantec Inc.

There were no companies that met the selected criteria that were intentionally excluded from the analyses.

Greentech reviewed, among other things, the EVs of the Selected Layne EPCs as a multiple of (a) calendar year 2017 estimated Adjusted EBITDA, and (b) calendar year 2018 estimated Adjusted EBITDA. Financial data of the Selected Layne EPCs were based on public filings and publicly available consensus estimates. Financial data of Layne were based on the Layne Forecasts. Implied equity values were derived from EVs by subtracting debt, preferred stock and minority interest and adding back cash and cash equivalents.

The overall low to high calendar year 2017 EV to estimated Adjusted EBITDA multiples observed for the Selected Layne EPCs were 7.7x to 16.5x (with a mean of 10.6x and a median of 8.8x). Greentech noted that, based on the closing stock price of shares of Layne Common Stock on February 12, 2018 and the Layne Forecasts, the implied calendar year 2017 EV to estimated Adjusted EBITDA multiple for Layne was 13.6x. Using its professional judgment and experience, Greentech selected and applied a range of EV to Adjusted EBITDA multiples of 8.5x to 11.5x to the estimated Adjusted EBITDA of Layne for calendar year 2017, based on the Layne Forecasts. This analysis indicated an implied per share equity value reference range for Layne of $5.46 to $9.63 (such range, “Layne 2017 Range”).

The overall low to high calendar year 2018 EV to estimated Adjusted EBITDA multiples observed for the Selected Layne EPCs were 6.4x to 10.3x (with a mean of 8.0x and a median of 8.1x). Greentech noted that, based on the closing stock price of shares of Layne Common Stock on February 12, 2018 and the Layne Forecasts, the implied calendar year 2018 EV to estimated Adjusted EBITDA multiple for Layne was 8.0x. Using its professional judgment and experience, Greentech then selected and applied a range of EV to Adjusted EBITDA multiples of 6.5x to 8.5x to the estimated Adjusted EBITDA of Layne for calendar year 2018, based on the Layne Forecasts. This analysis indicated an implied per share equity value reference range for Layne of $9.08 to $13.81 (such range, “Layne 2018 Range”).

Granite. In performing a selected public companies analysis of Granite, Greentech reviewed publicly available financial and stock market information for Granite and the following ten selected companies that Greentech viewed as generally relevant as publicly traded Engineering, Procurement and Construction companies (the “Selected Granite EPCs”):

•

AECOM

•

Aegion Corporation

•

Downer EDI Limited

- 86 -

•

MasTec, Inc.

•

Orion Group Holdings, Inc.

•

Primoris Services Corporation

•

Sterling Construction Company, Inc.

•

Tetra Tech, Inc.

•

Tutor Perini Corporation

Greentech reviewed, among other things, EVs of the Selected Granite EPCs as a multiple of (a) calendar year 2017 estimated Adjusted EBITDA, and (b) calendar year 2018 estimated Adjusted EBITDA. Greentech reviewed the low end of Adjusted EBITDA (“2018E Low End Adjusted EBITDA”) and the high end of Adjusted EBITDA (“2018E High End Adjusted EBITDA”) for calendar year 2018. Financial data of the Selected Granite EPCs were based on public filings and publicly available consensus estimates. Financial data of Granite were based on the Granite Forecasts.

The overall low to high calendar year 2017 EV to Adjusted EBITDA multiples observed for the Selected Granite EPCs were 6.5x to 12.6x (with a mean of 9.3x and a median of 8.9x). Greentech noted that, based on the closing stock price of shares of Granite Common Stock on February 12, 2018 and the actual Adjusted EBITDA for Granite for calendar year 2017, the implied calendar year 2017 EV to Adjusted EBITDA multiple for Granite was 14.5x. Using its professional judgment and experience, Greentech then selected and applied a range of EV to Adjusted EBITDA multiples of 8.0x to 10.0x to the actual Adjusted EBITDA of Granite as provided in the Granite Forecasts. This analysis indicated an implied per share equity value reference range for Granite of $33.26 to $41.62 (such range, “Granite 2017 Range”).

The overall low to high calendar year 2018 EV to estimated Adjusted EBITDA multiples observed for the Selected Granite EPCs were 5.3x to 12.0x (with a mean of 7.8x and a median of 7.1x). Greentech noted that, based on the closing stock price of shares of Granite Common Stock on February 12, 2018 and the 2018E Low End Adjusted EBITDA, the implied calendar year 2018 EV to estimated Adjusted EBITDA multiple for Granite was 11.0x. Greentech noted that, based on the closing stock price of shares of Granite Common Stock on February 12, 2018 and the 2018E High End Adjusted EBITDA, the implied calendar year 2018 EV to estimated Adjusted EBITDA multiple for Granite was 9.2x. Using its professional judgment and experience, Greentech then applied a range of EV to Adjusted EBITDA multiples of 6.0x to 9.5x to the 2018E Low End Adjusted EBITDA and 2018E High End Adjusted EBITDA, respectively. This analysis indicated an implied per share EV reference range for Granite of $33.07 to $52.47 using the 2018E Low End Adjusted EBITDA (such range, “Granite 2018 Range A”) and an implied per share equity value reference range of $39.27 to $62.28 using the 2018E High End Adjusted EBITDA (such range, “Granite 2018 Range B”).

Utilizing the implied per share equity value reference ranges derived for Layne and Granite described above, Greentech calculated the following implied Exchange Ratio reference ranges, as compared to the Exchange Ratio:

No company or business used in these analyses is identical or directly comparable to Layne or Granite. Accordingly, an evaluation of the results of these analyses is not entirely mathematical. Rather, these analyses

- 87 -

involve complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading or other values of the companies or businesses to which Layne or Granite were compared.

Selected Precedent Transactions Analysis

Greentech analyzed certain publicly available information relating to the following selected transactions in the Engineering, Procurement and Construction segment since October 2015:


Month / Year Announced	Target	Acquiror	EV/LTM Adjusted EBITDA Multiple		EV/NTM Adjusted EBITDA Multiple
December 2017	Pure Technologies	Xylem		24.2x	18.7x
October 2017	Aecon Group	China Communications Construction Co.		9.2x	7.5x
August 2017	CH2M Hill	Jacobs Engineering Group		10.1x	n/a
April 2017	WS Atkins	SNC-Lavalin Group		13.3x	11.5x
March 2017	Amec Foster Wheeler	John Wood Group		10.2x	10.4x
March 2016	MWH Global	Stantec		9.8x	n/a
November 2015	Furmanite Global	Team, Inc.		9.9x	8.1x
October 2015	Coffey International	Tetra Tech		7.3x	7.0x
October 2015	Professional Service Industries	Intertek Group		7.7x	n/a

There were no transactions that met the selected criteria that were intentionally excluded from this list. For purposes of Greentech’s analyses, the Pure Technologies-Xylem transaction was excluded from the range of multiples used because Greentech believed that the multiple in that transaction, which was determined to be two standard deviations above the mean, did not reflect an appropriate high-end for the segment.

For each of the selected transactions, Greentech calculated and compared EV as a multiple of the target’s LTM Adjusted EBITDA as most recently disclosed at the time of the announcement of the transaction (“EV/LTM Adjusted EBITDA Multiple”). Using its professional judgment and experience, Greentech applied an illustrative range of EV/LTM Adjusted EBITDA Multiples of 7.3x to 13.3x to Layne’s LTM Adjusted EBITDA for calendar year 2017, as provided to Greentech by the management of Layne. Greentech’s analysis resulted in an implied per share equity value reference range for Layne of $5.87 to $11.86.

Greentech also calculated and compared EV as a multiple of the target’s next twelve months’ Adjusted EBITDA as most recently disclosed at the time of the announcement of the transaction (“EV/NTM Adjusted EBITDA Multiple”). Using its professional judgment and experience, Greentech applied an illustrative range of EV/NTM Adjusted EBITDA Multiples of 7.0x to 11.5x to Layne’s NTM Adjusted EBITDA for calendar year 2018, as provided to Greentech by the management of Layne. Greentech’s analysis resulted in an implied per share equity value reference range for Layne of $10.52 to $18.10.

No transaction used in this analysis as a comparison is identical to the transactions contemplated by the Merger Agreement (including, without limitation, the Merger), and they all differ in material ways. While none of the companies involved in the selected transactions are directly comparable to Layne, these transactions were selected, among other reasons, because the businesses involved in these transactions share similar business characteristics to Layne based on business sector participation, operational characteristics and financial metrics. Accordingly, an analysis of the results described above is not mathematical; rather it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies involved and other factors that could affect the acquisition value of the transactions to which they are being compared. Implied equity values were derived from EVs by subtracting debt, preferred stock and minority interest and adding back cash and cash equivalents.

Premium Paid Analysis

Greentech reviewed the premium paid in completed transactions announced after January 1, 2015, valued between $250 million and $1 billion, in which the target was publicly traded and headquartered in North America or Europe and at least 50% of the consideration paid consisted of stock. Greentech excluded targets in the real estate and financial services industries. For each transaction, Greentech calculated the premium per share paid by the acquirer by comparing the announced transaction value per share to the target company’s share price one trading day prior to announcement.

The reasons for and the circumstances surrounding each of the transactions analyzed in the premium paid analysis were diverse and there are inherent differences between the business, operations, financial condition and prospects of Layne and the companies included in the premium paid analysis. Accordingly, a purely quantitative premium paid analysis may not be particularly meaningful in the context of considering the proposed transaction. Using its professional judgement and experience, Greentech selected and applied a range of premiums of 13.4% to 32.0% to the closing per share price of Layne Common Stock of $12.57 as of February 12, 2018 to calculate a range of implied equity prices per share of Layne Common Stock of $14.25 to $16.59.

Other Analyses

In rendering its opinion, Greentech also reviewed and considered other factors, including:

•

historical trading performance of Layne Common Stock and Granite Common Stock during the 52-week period ended February 12, 2018, which indicated low and high closing prices for Layne Common Stock and Granite Common Stock during such period of $7.24 and $13.63 per share and $45.71 and $67.84 per share, respectively and a corresponding illustrative range of Exchange Ratios of 0.107 to 0.298, as compared to the closing price of Layne Common Stock and Granite Common Stock on February 12, 2018 of $12.57 per share and $59.70 per share, respectively, and the Exchange Ratio of 0.270;

•

historical trading performance of Layne Common Stock and Granite Common Stock during the 104-week period ended February 12, 2018, which indicated low and high closing prices for Layne Common Stock and Granite Common Stock during such period of $5.11 and $13.63 per share and $36.25 and $67.84 per share, respectively, and a corresponding illustrative range of Exchange Ratios of 0.075 to 0.376, as compared to the closing price of Layne Common Stock and Granite Common Stock on February 12, 2018 of $12.57 per share and $59.70 per share, respectively, and the Exchange Ratio of 0.270; and

•

publicly available research analysts’ price targets for Layne Common Stock and Granite Common Stock, which indicated a price target for Layne Common Stock of $11.00 per share and high and low price targets for Granite Common Stock of $64.00 to $85.00 per share as compared to the closing price of Layne Common Stock and Granite Common Stock on February 12, 2018 of $12.57 per share and $59.70 per share, respectively.

Miscellaneous

The summary set forth above does not purport to be a complete description of all the analyses performed by Greentech. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of these methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to partial analysis or summary description. Greentech did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, notwithstanding the separate factors summarized above, Greentech believes, and has advised the Layne Board, that its analyses must be considered as a whole and that selecting portions of its analyses and the factors considered by it, without considering all analyses and factors, could create an incomplete view of the process underlying Greentech’s opinion. Greentech used these analyses to determine the impact of various

- 89 -

operating metrics on the implied EVs and equity values of Layne or Granite to the extent applicable. Each of these analyses yielded a range of implied EVs and equity values, and therefore, such implied EV and equity value ranges developed from these analyses were viewed by Greentech collectively and not individually.

In performing its analyses, Greentech assumed the continuation of normal economic conditions and business practices and the absence of material litigation issues. Except as otherwise noted, the information utilized by Greentech in its analyses, to the extent that it was based on market data, is based on market data as it existed on or before February 12, 2018 and is not necessarily indicative of current market conditions. These analyses performed by Greentech are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by such analyses. Accordingly, such analyses and estimates are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors. None of Layne, Granite, Greentech or any other person assumes responsibility if future results are materially different from those projected. The analyses supplied by Greentech and its opinion were among several factors taken into consideration by the Layne Board in making its decision to enter into the Merger Agreement and should not be considered as determinative of such decision.

The type and amount of consideration payable in the Merger was determined through negotiations between Layne and Granite, rather than by any financial advisor, and was approved by the Layne Board. The decision by Layne to enter into the Merger Agreement was solely that of the Layne Board. As described above, Greentech’s opinion and analyses were only one of many factors considered by the Layne Board in its evaluation of the proposed Merger and should not be viewed as determinative of the views of the Layne Board or management with respect to the Merger.

In accordance with an engagement letter between Layne and Greentech, dated June 23, 2017 (the “Engagement Letter”), Layne has agreed to pay Greentech for its services in connection with the Merger (a) an aggregate fee of approximately $8 million (the “Transaction Fee”), which is contingent upon the consummation of the Merger, (b) a fee of $750,000 payable upon the delivery of Greentech’s opinion, 50% of which is creditable against the Transaction Fee, and (c) a fee of $200,000 paid at the execution of the Engagement Letter and also creditable against the Transaction Fee. Layne also has agreed to reimburse Greentech for its expenses incurred in connection with Greentech’s engagement and to indemnify Greentech, its affiliates and each of their respective directors, officers, employees, agents and controlling persons against specified liabilities. In the two years preceding the date of its opinion, Greentech had not had a material relationship with Layne or any other party to the Merger and there were no material relationships mutually understood to be contemplated in which any compensation was received or was intended to be received as a result of the relationship between Greentech and any party to the Merger. Greentech and its affiliates may in the future provide commercial and investment banking services to Layne, Granite or their respective affiliates and may receive fees for the rendering of such services.

The terms of the fee arrangement, which are customary in transactions of this nature, were negotiated at arm’s length between Greentech and Layne, and the Layne Board was aware of the arrangement, including the fact that the Transaction Fee is contingent upon the completion of the Merger.

Greentech, as part of its investment banking services, is regularly engaged in the independent valuation of businesses and securities in connection with mergers, acquisitions, private placements and valuations for corporate and other purposes. In the ordinary course of its business, Greentech and its affiliates may actively trade the securities of Layne or Granite for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

Certain Information Provided by the Parties

In the course of negotiating the Merger Agreement, Granite and Layne exchanged certain non-public information as part of the customary “due-diligence” process. As part of this process, Granite and Layne allowed

- 90 -

each other, and each other’s respective representatives, access, to data rooms that contained non-public information that concerned Granite and Layne, as well as their operations. In addition to the information supplied as part of this process, Granite and Layne each prepared or provided certain prospective financial information to share with the other party and their respective financial advisors. The prospective financial information provided by Granite consisted of projections for the calendar years 2018 through 2020. The prospective financial information provided by Layne consisted of projections as well as additional financial and operating data for the fiscal years 2018 through 2022. Each of Layne and Granite considered the prospective financial information provided by the other party. The prospective financial information disclosed below summarizes the key information that was exchanged and relied upon by the parties.

Granite Unaudited Prospective Financial Information

Although Granite periodically may issue limited guidance to investors concerning its expected financial performance, Granite does not, as a matter of course, publicly disclose detailed financial projections. However, in connection with the negotiation of the Merger, Granite management provided the Granite Forecasts to the Granite Board, Perella Weinberg, Layne and Greentech.

While the Granite Forecasts are being included in this proxy statement/prospectus, the Granite Forecasts were not prepared with a view toward public disclosure, complying with the published guidelines of the SEC regarding projections and the use of non-GAAP measures or complying with the published guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of “prospective financial information.” In the view of Granite management, the Granite Forecasts were prepared on a reasonable basis and reflected the best-available estimates and judgments of Granite management, as of the time of their preparation. The inclusion of the Granite Forecasts in this proxy statement/prospectus should not be regarded as an indication that Granite or any other recipient of this information considered, or now considers, this information to be predictive of actual future results, nor does it constitute an admission or representation by any person that such information is material. Readers are cautioned not to place undue reliance on the prospective financial information.

The Granite Forecasts are unaudited. This prospective financial information included in this proxy statement/ prospectus has been prepared by, and is the responsibility of, Granite’s management. PricewaterhouseCoopers LLP has neither audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying prospective financial information and, accordingly, PricewaterhouseCoopers LLP does not express an opinion or any other form of assurance with respect thereto. The PricewaterhouseCoopers LLP report included in this proxy statement/ prospectus relates to Granite’s historical financial information. It does not extend to the prospective financial information and should not be read to do so.

The Granite Forecasts:

•

The Granite Forecasts below also include several key assumptions surrounding the timing, impact and availability of incremental public funding at local, state and national levels. As a result, the Granite Forecasts may not accurately reflect the timing of expected, increased demand, Granite’s related or estimated capture of expected, increased demand, or when related project activity would be realized within Granite’s financial statements, including any impacts to the competitive environment in key geographic and vertical end markets.

The prospective financial information set forth herein regarding EBITDA (defined as earnings before interest, income taxes, depreciation and amortization expense) may be considered a non-GAAP financial measure. Granite provided this information to its advisors and to Layne and its advisors, because Granite believed it could be useful in evaluating, on a prospective basis, Granite’s potential operating performance and cash flow. EBITDA should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and EBITDA as used by Granite may not be comparable to similarly titled amounts used by other companies.

Layne Unaudited Prospective Financial Information

Layne, as a matter of course, does not make public disclosure of detailed forecasts or projections of its expected financial performance due to, among other things, the inherent difficulty of accurately predicting future periods and the likelihood that the underlying assumptions and estimates may prove incorrect. However, in connection with the negotiation and execution of the Merger Agreement, and having consulted with Greentech, its financial advisor, Granite and Perella Weinberg, Granite’s financial advisor, Layne provided the Layne Board, Greentech, Granite and Perella Weinberg with certain non-public internal financial projections regarding Layne’s anticipated future operations.

The financial projections summarized below were not prepared with a view toward public disclosure or with a view toward complying with the published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information, but, in the view of Layne management, such projections reflect the best currently available estimates and judgments of Layne management as of the time of their preparation. Neither Layne’s independent auditor, Deloitte, which is listed as an expert below in “Experts,” nor Greentech compiled, examined or performed any procedures with respect to the projections summarized herein, and has not expressed any opinion or any other form of assurance on such information or its achievability, and assumes any responsibility for, and disclaims any association with, such projections. The independent auditor’s reports included or incorporated by reference in this proxy statement/prospectus relate to historical financial statements. They do not extend to any prospective financial information and should not be seen to do so.

Although presented with numerical specificity, the projections were prepared in the context of numerous variables, estimates and assumptions that are inherently uncertain and may be beyond the control of Layne, and which may prove not to have been, or may no longer be, accurate. The projections are subject to many risks and uncertainties. Important factors that may affect actual results and cause actual results to differ materially from

- 92 -

these projections include, but are not limited to, risks and uncertainties relating to Layne’s business (including its ability to achieve strategic goals, objectives and targets over the applicable periods), industry performance, the regulatory environment, general business and economic conditions, market and financial conditions, Layne’s capital structure and refinancing assumptions over the forecast period, various risks set forth in Layne’s reports filed with the SEC, and other factors described or referenced under “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 31 of this proxy statement/prospectus.

The projections also reflect assumptions that are subject to change and are susceptible to multiple interpretations and periodic revisions based on actual results, revised prospects for Layne’s business, changes in general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the projections were prepared. In addition, the projections do not take into account any of the transactions contemplated by the Merger Agreement, including the Merger and associated expenses, or Layne’s compliance with its respective covenants under the Merger Agreement. Further, the projections do not take into account any circumstances, transactions or events occurring after the date they were prepared. Accordingly, actual results will likely differ, and may differ materially, from those contained in the projections. There can be no assurance that these projections will be realized or that future financial results of Layne (or, following consummation of the Merger, Granite) will not materially vary from these projections.

Layne is providing a summary of prospective financial information regarding Layne and Granite, respectively, solely to give stockholders access to the information that Layne management made available to the Layne Board, Greentech, Granite and Perella Weinberg.

The forecasted financial information presented below for Layne, which reports on a January 31st fiscal year-end basis, was prepared by Layne and was modified by Greentech at the direction and as approved by Layne to be presented to the Layne Board on a calendar-year basis for comparative purposes.

For Layne, Adjusted EBITDA is defined as Layne’s net income (loss) before discontinued operations, taxes, interest, depreciation and amortization, gain or loss on sale of fixed assets, equity in earnings or losses from affiliates, certain non-recurring items such as restructuring costs, and certain other gains or losses, plus dividends received from affiliates. The definition of Adjusted EBITDA used herein differs from the definition presented in Layne’s periodic reports filed with the SEC. Adjusted EBITDA is a non-GAAP

- 93 -

financial measure, as it excludes amounts, or is subject to adjustments that effectively exclude amounts, included in the most directly comparable measure calculated and presented in accordance with GAAP in financial statements. Adjusted EBITDA is used by Layne’s management to provide additional information in order to provide them with an alternative method for assessing Layne’s, Granite’s and the combined company’s financial condition and operating results (including in comparison to other similar companies). These measures are not in accordance with, or a substitute for, GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. Adjusted EBITDA should not be considered in isolation or as a substitute for net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP or as a measure of a company’s profitability or liquidity.

(2)

For Layne, Free Cash Flow is defined as Layne’s earnings before interest and income taxes, less taxes, plus depreciation and amortization, less capital expenditures, plus or minus changes in net working capital, as applicable, less gain on sale of assets and income attributable to non-controlling interest. Free Cash Flow is used by Layne’s management to provide additional information with respect to available cash and liquidity. These measures are not in accordance with, or a substitute for, GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. Free Cash Flow should not be considered in isolation or as a substitute for cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP or as a measure of a company’s profitability or liquidity.

EBITDA was calculated by Greentech as Granite’s net income plus taxes, net interest expense, and depreciation and amortization expense, and approved by Layne for Greentech’s use. EBITDA is a non-GAAP financial measure, as it excludes amounts, or is subject to adjustments that effectively exclude amounts, included in the most directly comparable measure calculated and presented in accordance with GAAP in financial statements. EBITDA was used by Layne’s management to provide additional information in order to provide them with an alternative method for assessing Layne’s, Granite’s and the combined company’s financial condition and operating results (including in comparison to other similar companies). These measures are not in accordance with, or a substitute for, GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. EBITDA should not be considered in isolation or as a substitute for net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP or as a measure of a company’s profitability or liquidity.

(5)

Free Cash Flow was calculated by Greentech as Granite’s earnings before interest and income taxes, less taxes, plus depreciation & amortization, less capital expenditures, plus or minus changes in net working capital, as applicable, less gain on sale of assets and income attributable to non-controlling interest and approved by Layne for Greentech’s use. Free Cash Flow is used by Layne’s management to provide additional information with respect to available cash and liquidity. These measures are not in accordance with, or a substitute for, GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. Free Cash Flow should not be considered in isolation or as a substitute for cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP or as a measure of a company’s profitability or liquidity.

The inclusion of a summary of the projections in this proxy statement/prospectus should not be regarded as an indication that any of Layne, Granite or their respective affiliates, officers, directors or other representatives consider the projections to be necessarily predictive of actual future events, and the projections should not be relied upon as such. None of Layne, Granite or their respective affiliates, officers, directors or other representatives can give any stockholder of Layne, Granite or other person any assurance that actual results will not differ materially from the projections, and, except as otherwise required by law, none of them undertakes any obligation to update or otherwise revise or reconcile the projections to reflect circumstances existing after the date the projections were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions and estimates underlying the projections are shown to be in error.

- 94 -

Readers are cautioned not to rely on the projections. Layne has not updated and, except as otherwise required by law, does not intend to update or otherwise revise the projections, even in the short term, to reflect circumstances existing after the date when made or to reflect the occurrence of future events, including the Merger. Further, the projections do not take into account the effect of any failure of the Merger to occur and should not be viewed as accurate or continuing in that context.

The prospective financial information presented here is not included in this proxy statement/prospectus in order to influence any stockholder to make any investment decision with respect to the Merger. The inclusion of this information should not be regarded as an indication that the Layne Board, its advisors or any other person considered, or now considers, it to be material or to be a reliable prediction of actual future results. The financial projections summarized below are subjective in many respects. There can be no assurance that these projections will be realized or that actual results will not be significantly higher or lower than forecasted. The projections included herein cover multiple years, and such information by its nature becomes subject to greater uncertainty with each successive year. The financial projections and summary information should be evaluated, if at all, in conjunction with the historical financial statements and other information contained in Layne’s public filings with the SEC.

Interests of Certain Persons in the Merger

In considering the information described in this proxy statement/prospectus, you should be aware that Layne’s executive officers and directors may have had economic interests in the Merger that are or were different from, or in addition to, those of Layne’s stockholders generally and that may create potential conflicts of interest. In addition to the rights described below in this section, the executive officers of Layne may be eligible to receive some of the generally applicable benefits described under the heading “The Merger Agreement—Employee Benefits Matters” on page 125. The Layne Board was aware of and considered those interests, among other matters, in reaching its decision to approve the Merger Agreement, the Merger and the transactions contemplated by the Merger Agreement.

Set forth below are the descriptions of the directors’ and executive officers’ interests including, but are not limited to, the treatment in the Merger of Layne’s equity compensation awards (including the acceleration of Layne Stock Options, Layne RSUs and Layne PSUs), severance plans and other rights that may be held by Layne’s directors and executive officers, and the indemnification of current and former Layne directors and officers by the Surviving Corporation. The dates used in the discussions below to quantify certain of these interests have been selected for illustrative purposes only, and they do not necessarily reflect the dates on which certain events will occur.

Equity Awards Held by Layne Directors and Executive Officers

Treatment of Outstanding Equity Awards in the Merger

The general treatment of Layne Stock Options, Layne RSUs and Layne PSUs in the Merger, including such awards held by Layne’s directors and executive officers, is described under section entitles “The Merger Agreement—Merger Consideration” beginning on page 106 of this proxy statement/prospectus.

The following table summarizes, as of March 9, 2018, the aggregate number of Layne Stock Options, Layne RSUs and Layne PSUs that are currently subject to vesting for each of Layne’s executive officers and directors, and that will become vested at the time of the Merger under the Layne 2006 Equity Incentive Plan, as amended, and award agreements, assuming continued employment through the Effective Time, and assuming the Effective Time occurs on May 31, 2018. The table also provides an estimate of the cash value of the Merger Consideration payable upon the settlement of these awards, in each case, solely as a result of the Merger. This cash value estimate is based on a per share value of Layne Common Stock of $16.01, which represents the average closing market price of Layne Common Stock over the first five business days following the first public announcement of the Merger.

Executive Severance Agreements

Layne has entered into severance agreements with the Executives, other than Mr. Purlee, which provide payments and benefits in connection with a termination of employment in certain circumstances, including enhanced benefits for certain terminations that occur in connection with a change in control. The Merger will constitute a change in control for purposes of each Executive’s severance agreement. The severance agreements subject these Executives to certain restrictive covenants including covenants not to compete, confidentiality and non-solicitation of Layne employees, which run during the term of the severance agreement. If an Executive fails to comply with these covenants (subject to a notice and right to cure period), the terminated Executive would not be entitled to receive the severance benefits described in this section. The severance agreements also contain covenants not to compete and non-solicitation provisions that apply for 24 months after termination with respect to Messrs. Caliel, Anderson and Crooke and for 12 months after termination with respect to Mr. Maher. The severance agreements with Messrs. Caliel, Anderson, Crooke and Maher generally provide:
