PROSPECTUS SUMMARY

This summary highlights information contained or incorporated by reference in this prospectus and may not contain all of the information that may be important to you. You should read the following summary together with the more detailed information regarding our company, our common stock and the financial statements and notes to those statements included in this prospectus or incorporated by reference in this prospectus by reference to our other filings with the Securities and Exchange Commission (the “SEC”). We urge you to read the entire prospectus carefully, especially the risks of investing in our common stock, which are discussed in the section entitled Risk Factors in this prospectus supplement, before making an investment decision.

Who We Are

We are a public utility holding company headquartered in Hampton, New Hampshire. We are subject to regulation as a holding company system by the Federal Energy Regulatory Commission (the “FERC”) under the Energy Policy Act of 2005.

Our principal business is the local distribution of electricity and natural gas throughout our service territories in the states of New Hampshire, Massachusetts and Maine. We are the parent company of three distribution utilities: (i) Unitil Energy Systems, Inc. (“Unitil Energy”), which provides electric service in the southeastern seacoast and state capital regions of New Hampshire, including the city of Concord; (ii) Fitchburg Gas and Electric Light Company (“Fitchburg”), which provides both electric and natural gas service in the greater Fitchburg area of north central Massachusetts; and (iii) Northern Utilities, Inc. (“Northern Utilities”), which provides natural gas service in southeastern New Hampshire, including the city of Portsmouth, and portions of southern and central Maine, including the city of Portland. In addition, we are the parent company of Granite State Gas Transmission, Inc. (“Granite State”), an interstate natural gas transmission pipeline company that principally provides interstate natural gas pipeline access and transportation services to Northern Utilities in its New Hampshire and Maine service territories.

Our distribution utilities serve approximately 100,300 electric customers and 69,300 natural gas customers in their service territories. Our distribution utilities are local “pipes and wires” operating companies and, combined with Granite State, had an investment in Net Utility Plant of $422.8 million at December 31, 2008 and $428.5 million at March 31, 2009. We do not own or operate electric generating facilities or major transmission facilities and substantially all of our utility assets are dedicated to the local delivery of electricity and natural gas to our customers. Our total revenue was $288.2 million in 2008 and $135.6 million for the three months ended March 31, 2009, which includes revenue to recover the cost of purchased electricity and natural gas in rates on a fully reconciling basis. As a result of this reconciling rate structure, our earnings are not affected by changes in the cost of purchased electricity and natural gas. Earnings applicable to common shareholders for 2008 were $9.6 million and for the three months ended March 31, 2009 were $9.1 million. Substantially all of our revenue and earnings are derived from regulated utility operations. Our consolidated operating results for 2008 reflect one month of financial activity for Northern Utilities and Granite State, which we acquired on December 1, 2008. The financial activity for Northern Utilities and Granite State is fully reflected in our consolidated operating results for the three months ended March 31, 2009. We have prepared the Pro Forma Statement of Earnings for the Twelve Months Ended December 31, 2008, which is included in this prospectus supplement, to reflect our acquisition of Northern Utilities and Granite State as if the businesses had actually been combined as of January 1, 2008.

Table of Contents

A fifth wholly owned subsidiary, Unitil Power Corp. (“Unitil Power”), formerly functioned as the full requirements wholesale power supply provider for Unitil Energy. In connection with the implementation of electric industry restructuring in New Hampshire, Unitil Power ceased being the wholesale supplier of Unitil Energy on May 1, 2003 and divested of substantially all of its long-term power supply contracts through the sale of the entitlements to the electricity associated with those contracts.

We also have three other wholly owned subsidiaries: Unitil Service Corp. (“Unitil Service”); Unitil Realty Corp. (“Unitil Realty”); and Unitil Resources, Inc. (“Unitil Resources”). Unitil Service provides, at cost, a variety of administrative and professional services, including regulatory, financial, accounting, human resources, engineering, operations, technology and energy supply management services on a centralized basis to its affiliated Unitil companies. Unitil Realty owns and manages our corporate office in Hampton, New Hampshire. Unitil Resources is our wholly owned non-regulated subsidiary. Usource, Inc. and Usource L.L.C. (collectively, “Usource”) are indirect subsidiaries that are wholly owned by Unitil Resources. Usource provides energy brokering and advisory services to large commercial and industrial (“C&I”) customers in the northeastern United States.

Business Strategy

Our business strategy is to be a leader in the reliable and cost effective management of a growing level of local electric and natural gas distribution assets. Our growth initiatives include evaluation of organic growth opportunities as well as strategic acquisitions. As part of our growth strategy, on December 1, 2008, we purchased (i) all of the outstanding capital stock of Northern Utilities from Bay State Gas Company (“Bay State”) and (ii) all of the outstanding capital stock of Granite State from NiSource Inc. (“NiSource”) pursuant to the Stock Purchase Agreement dated as of February 15, 2008 by and among NiSource, Bay State and us. Bay State is a subsidiary of NiSource. We refer to these transactions as the “Acquisitions.” The aggregate purchase price for the Acquisitions was $160 million in cash, plus an additional working capital adjustment of $49.2 million, including approximately $30.0 million of natural gas storage inventory. To finance the Acquisitions and recapitalize Northern Utilities and Granite State, we issued additional equity and debt. Please see the sections entitled Risk Factors—Risks Relating to Our Business and Prospectus Summary—Summary Unaudited Pro Forma Combined Financial Data in this prospectus supplement.

Our Strengths

We believe our strengths have enabled us to grow our business profitably and create shareholder value. These strengths include:

Growing Service Territories. Our operations are located in the southeastern seacoast and state capital regions of New Hampshire, the greater Fitchburg area of north central Massachusetts, and portions of southern and central Maine. These service territories provide a diverse and growing customer base. As a result of the Acquisitions, we added approximately 54,000 natural gas customers and extended our operations into Maine.

Regulated Asset Base. Our core assets consist of retail distribution facilities necessary for the delivery of our customers’ electric and natural gas supply needs within our service territories and regulatory assets related to our regulated utility operations. Our electric and natural gas distribution assets and regulatory assets, from which we derive substantially all of our operating income, provide stable earnings and cash flow. The Acquisitions increased our assets by approximately 55%, contributing to significant growth of our retail distribution facilities.

 

 

S-2


Table of Contents

Diversified Customer Base. Our customers are a diversified mix of residential and C&I customers, with no single customer representing more than 5% of our total revenues. Our sales to large C&I customers are not concentrated in one industry segment but vary from government facilities to large retail outlets, colleges and hospitals and a broad range of industrial companies that reflect the diverse nature of the communities that we serve. The Acquisitions increased our customer base by approximately 54,000 natural gas customers and provided further diversification to our operations with respect to geography (into Maine) and utility business mix (between our gas and electric divisions).

Efficient and Flexible Operating Structure. We believe that due in part to our size and the proximity of our utility operations, we are able (i) to expeditiously and effectively respond to changing regulatory and public policy initiatives, (ii) to leverage new technology solutions that significantly improve productivity and customer service, and (iii) to implement organizational changes that improve our performance. We have a proven track record of successfully transitioning our company to meet the business and operational challenges affecting our industry.

Historic Dividend Stability. Since our incorporation in 1984, we have continuously paid quarterly dividends and we have never reduced our dividend rate, while still increasing our investment in our utility distribution facilities. We expect to maintain our current dividend policy while providing for future growth of earnings available to shareholders.

Experienced Management Team. Our senior management team is highly experienced in the utility industry. As of May 2009, our Chairman and Chief Executive Officer, Robert Schoenberger, had 31 years of industry experience. As of May 2009, our senior management team as a whole averaged approximately 24 years experience in the industry and 17 years experience with us.

Summary Historical Consolidated Financial Information

The following table contains summary historical consolidated financial information, including per share information, for each of the periods indicated. The summary historical consolidated financial information as of and for each of the years in the three-year period ended December 31, 2008 was derived from our consolidated financial statements as filed with the SEC in our Form 10-K for the year ended December 31, 2008, which were audited by Caturano and Company, P.C. (formerly known as Vitale, Caturano & Company, P.C.) and which statements are incorporated by reference in this prospectus. The summary historical consolidated financial information as of and for the three months ended March 31, 2009 and 2008 was derived from our unaudited consolidated financial statements as filed with the SEC in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2009, which statements are incorporated by reference in this prospectus. See the section entitled Where You Can Find More Information in this prospectus supplement.

The summary historical consolidated financial information should be read in conjunction with our audited financial statements, our unaudited interim financial statements and the related notes and the section entitled Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10-K for the year ended December 31, 2008 and our Form 10-Q for the quarter ended March 31, 2009. Our financial results for the three months ended March 31, 2009 are not necessarily indicative of the results that may be expected for an entire year.

Sales of natural gas and the related results of operations can be significantly affected by seasonal weather conditions. Annual revenues are substantially realized during the heating season as a result of higher sales of natural gas due to cold weather. Accordingly, our operating results historically are most favorable in the first and fourth calendar quarters. Therefore, fluctuations in seasonal weather conditions between years may have a significant effect on our results of operations and cash flows.

Sales of electricity are generally less sensitive to weather than natural gas sales, but may also be affected by weather conditions in both the winter and summer seasons.

Summary Unaudited Pro Forma Combined Financial Data

The following summary unaudited pro forma combined financial data (the “Summary Pro Forma Financial Data”) and the unaudited pro forma combined statements of earnings and explanatory notes beginning on page F-1 (the “Pro Forma Statements of Earnings”) have been prepared to give effect to the Acquisitions as if the businesses had actually been combined as of January 1, 2008.

The Summary Pro Forma Financial Data and the Pro Forma Statements of Earnings include adjustments for the Acquisitions pursuant to the purchase method of accounting for business combinations. The Pro Forma Statements of Earnings include adjustments to give effect to:

 

  (i)   the receipt of the estimated net proceeds of approximately $42.1 million from the issuance of 2,000,000 shares of common stock in this offering at an assumed offering price of $22.49 per share, which was the closing price of our common stock on May 13, 2009, and the application of the estimated net proceeds of this offering as described in Use of Proceeds in this prospectus supplement;

 

  (ii)   the issuance of 2,000,000 shares of common stock in December 2008 and 270,000 shares in January 2009, the net proceeds of approximately $41.9 million were used to partially finance the Acquisitions;

 

  (iii)   the sale and issuance in December 2008 by Northern Utilities of $80.0 million aggregate principal amount of long-term unsecured notes; and

 

  (iv)   the sale and issuance by Granite State in December 2008 of $10.0 million aggregate principal amount of long-term unsecured notes;

The Summary Pro Forma Financial Data and the Pro Forma Statements of Earnings exclude adjustments to recognize:

 

  (i)   estimated annual operating expense savings of $5.6 million (before tax) due to the achievement of efficiencies associated with the provision of shared utility services and the adoption of best practices associated with these shared utility services (excluding the portion of savings realized and included in the periods ended March 31, 2009 and December 31, 2008);

 

  (ii)   reductions in operating expenses of $2.5 million (after tax) related to compliance violation penalties incurred by Northern Utilities, prior to the Acquisitions, in the twelve months ended March 31, 2009 and December 31, 2008;

 

  (iii)   increases in Gas Operating Revenue of $0.3 million (before tax) and $0.4 million (before tax) and resulting increases in gross operating margin, for the twelve months ended March 31, 2009 and December 31, 2008, respectively, related to increased rates authorized by regulators for Granite State; and

 

  (iv)   enhancements to net income that may occur from the execution of our regulatory plan.

The Summary Pro Forma Financial Data and the Pro Forma Statements of Earnings assume that Unitil financed the Acquisitions and the related costs and expenses using the net proceeds from the above-referenced sale and issuance of common stock, the above-referenced sale and issuance of long-term unsecured notes and the financing by Northern Utilities of its gas inventory.

The Summary Pro Forma Financial Data and the Pro Forma Statements of Earnings have been derived from and should be read together with our historical consolidated financial statements and the related notes, which are incorporated by reference herein, and the historical financial statements and the related notes of both Northern Utilities and Granite State, which are incorporated by reference in this prospectus.

RISK FACTORS

Before making an investment in shares of our common stock, you should carefully consider the risks described below and the information included or incorporated by reference in this prospectus supplement and the accompanying prospectus. We have identified a number of these risks in our Annual Report on Form 10-K for the year ended December 31, 2008 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2009, each of which is incorporated by reference into this prospectus. See the section entitled Where You Can Find More Information in this prospectus supplement. In addition, you should carefully consider the risks and uncertainties referred to below or listed under the section entitled Cautionary Statement about Forward-Looking Statements in this prospectus supplement.

Risks Relating to Our Business

For a description of risks relating to our business, please see our Annual Report on Form 10-K for the year ended December 31, 2008 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2009, each of which is incorporated by reference into this prospectus.

Risks Relating to the Acquisitions

If we are unsuccessful in effectively integrating Northern Utilities and Granite State, we may not be able to operate cost-efficiently. Our ability to achieve the benefits of the Acquisitions depends in part on successfully integrating Northern Utilities’ and Granite State’s operations, services, and personnel in a timely and efficient manner. This involves integrating systems, applications, policies, procedures, business processes, and other operations and requires coordination of administrative staff and development and engineering teams. We expect to incur significant costs integrating Northern Utilities and Granite State and integration may be difficult, unpredictable, and subject to delay because of possible cultural conflicts and differing opinions. Additionally, integration could divert management’s attention away from our operations, which could harm our business, financial condition and operating results. If we cannot successfully integrate Northern Utilities and Granite State, we will not realize the expected benefits of the Acquisitions, including reduced operating expenses and cash flow savings, and may not be able to operate cost-efficiently.

Our ability to execute a reasonable regulatory plan for Northern Utilities and Granite State depends upon regulatory action under applicable statutes, rules and regulations. We believe there is an opportunity to stabilize and improve the operating earnings of Northern Utilities and Granite State by executing a consistent and well-structured regulatory plan that will provide Northern Utilities and Granite State with an opportunity to earn a reasonable rate of return. If we are unable to obtain approval of a reasonable regulatory plan, or are delayed in obtaining approval of a reasonable regulatory plan, we may not be able to improve the operating earnings of Northern Utilities and Granite State. Also, pursuant to the Maine Public Utilities Commission’s and the State of New Hampshire Public Utilities Commission’s orders authorizing our acquisition of Northern Utilities, we cannot seek base rate relief in Maine or New Hampshire until November 1, 2010, subject to certain exceptions. We will retain any synergy savings resulting from the Acquisitions until the next base rate change and then such savings will flow through to our customers.

We could be exposed to unknown liabilities of Northern Utilities and Granite State, which could cause us to incur substantial financial obligations and harm our business. If Northern Utilities and Granite State have liabilities of which we are not aware, we have assumed those liabilities and may have limited recourse against NiSource and Bay State. If such unknown liabilities exist and we are not fully

indemnified for any loss that we incur as a result thereof, we could incur substantial financial obligations, which could adversely affect our financial condition and harm our business.

Risks Relating to this Offering

Our stock price may decline when our results decline or when events occur that are adverse to us or our industry. You can expect the market price of our common stock to decline when our results decline or at any time when events actually or potentially adverse to us or the electricity and gas industry occur. Our common stock price may decline to a price below the price you paid to purchase your shares of common stock in this offering.

Substantial sales of our common stock could cause our stock price to decline. If we or our existing shareholders sell a large number of shares of our common stock or the public market perceives that we or our existing shareholders might sell shares of our common stock, the market price of our common stock could significantly decline. All of the shares offered by this prospectus supplement will be freely tradable without restriction or further registration under the federal securities laws unless purchased by an “affiliate,” as that term is defined in Rule 144 under the Securities Act. The outstanding shares subject to lock-up agreements between each of our directors and our senior executive officers and the underwriters may be sold 90 days after the date of this prospectus supplement, except as noted in the section entitled Underwriting in this prospectus supplement. Significant shareholders who are neither directors nor senior executive officers are not subject to lock-up agreements. Please see the section entitled Voting Securities and Principal Holders Thereof in this prospectus supplement.

The proposed sale and issuance of common stock will reduce the proportionate share of the holdings of our current shareholders. As of May 19, 2009, we had 8,113,027 shares of common stock outstanding. If the proposed sale and issuance of common stock is consummated, we will have approximately 10,513,027 shares of common stock outstanding (10,873,027 shares if the underwriters exercise their over-allotment option). As a result, our shareholders’ proportionate holding in us would be reduced by approximately 22.8% (25.4% if the underwriters exercise their over-allotment option).

All statements, other than statements of historical fact, included or incorporated by reference into this prospectus, including, without limitation, statements regarding the financial position, business strategy and other plans and objectives for our future operations, are forward-looking statements.

These statements include declarations regarding our or our management’s beliefs and current expectations. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of such terms or other comparable terminology. These forward-looking statements are subject to inherent risks and uncertainties in predicting future results and conditions that could cause the actual results to differ materially from those projected in these forward-looking statements. Some, but not all, of the risks and uncertainties include those described in the section entitled Risk Factors in this prospectus supplement and the following:

 

  Ÿ  

our ability to integrate the business, operations, and personnel of Northern Utilities and Granite State and to achieve the estimated potential synergy savings attributable to the Acquisitions;

 

  Ÿ  

our ability to retain existing customers and gain new customers;

 

  Ÿ  

variations in weather;

 

  Ÿ  

major storms;

 

  Ÿ  

changes in the regulatory environment;

 

  Ÿ  

customers’ preferences on energy sources;

 

  Ÿ  

interest rate fluctuation and credit market concerns;

 

  Ÿ  

general economic conditions including recent distress in the financial markets, which has had an adverse impact on the availability of credit and liquidity resources generally and could jeopardize certain of our counterparty obligations, including those of our insurers and financial institutions;

 

  Ÿ  

fluctuations in supply, demand, transmission capacity and prices for energy commodities;

 

  Ÿ  

increased competition; and

 

  Ÿ  

customers’ performance under multi-year energy brokering contracts.

Many of these risks are beyond our control. Any forward-looking statements speak only as of the date of this prospectus supplement, and we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date on which such statements are made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict all of these factors, nor can we assess the impact of any such factor on our business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statements.

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately $45.0 million (approximately $51.8 million if the underwriters’ exercise their over-allotment option in full), after deducting the underwriting discounts and our estimated offering expenses, based on the public offering price of $20.00 per share.

We intend to use the net proceeds from this offering (including the proceeds from any exercise by the underwriters of their over-allotment option) (i) to repay all amounts outstanding under the bridge credit facility that we used to partially finance the Acquisitions and the related costs and expenses (approximately $39.1 million) and (ii) for other general corporate purposes, including capital contributions to our distribution utilities and repayment of short-term debt.

Amounts outstanding under the bridge credit facility accrue interest at either the Eurodollar Rate or the base rate, in each case plus the applicable margin. The Eurodollar Rate is based on an applicable LIBOR (the London Interbank Offered Rate) as increased by statutory reserve requirements. The base rate is the higher of (i) the rate of interest announced publicly by Royal Bank of Canada from time to time and (ii) the Federal Funds Rate plus 0.50%. The applicable margin is a range of interest rates that varies from 2.50% to 5.00% depending on the remaining term of the borrowings. The bridge credit facility matures on November 1, 2009.

We have granted to the underwriters a 30-day option to purchase on a pro rata basis up to 360,000 additional shares at the offering price less the underwriting discounts and commissions. The option may be exercised only to cover any over-allotments of common stock.

The underwriters propose to offer the shares of common stock directly to the public at the offering price on the cover page of this prospectus and to selling group members at that price less a selling concession of $0.63 per share. After the offering, RBC Capital Markets Corporation may change the offering price and concession and discount to broker/dealers. The underwriters and selling group members may allow a discount of $0.10 per share on sales to other broker/dealers. The expenses of the offering that are payable by us are estimated to be $0.5 million (exclusive of underwriting discounts and commissions).

Our executive officers and directors have agreed that they will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, enter into a transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of our common stock, whether any of these transactions are to be settled by delivery of our common stock or other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of RBC Capital Markets Corporation for a period of 90 days after the date of this prospectus, provided, however, that the foregoing shall not apply to any transfer that is a bona fide gift or any transfer to a trust for the benefit of the officer or director or an immediate family member, provided the transferee agrees to be bound in writing by the terms of the agreement.

The 90-day restricted period described in the preceding paragraphs will be automatically extended if: (i) during the last 17 days of the 90-day restricted period we issue an earnings release or announce material news or a material event; or (ii) prior to the expiration of the 90-day restricted period, we announce that we will release earnings results during the 15-day period following the last day of the 90-day period, in which case the restrictions described in the preceding paragraph will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release of the announcement of the material news or material event.

We have agreed to indemnify the underwriters against liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in that respect.

Our common stock is listed on the New York Stock Exchange under the symbol “UTL.”

In the ordinary course of business, certain of the underwriters and their affiliates have provided and may in the future provide financial advisory, investment banking and general financing and banking services for us and our affiliates for customary fees. Each of the underwriters served as underwriters in our offering of 2,270,000 shares of common stock in December 2008 and January 2009.

RBC Capital Markets Corporation:

 

  Ÿ  

served as book-running manager in our offering of 2,270,000 shares of common stock in December 2008 and January 2009;

 

  Ÿ  

acted as a placement agent in connection with the private placement of certain of our debt securities;

 

  Ÿ  

acted as financial advisor in connection with the Acquisitions;

 

  Ÿ  

is the lender under the bridge credit facility that we used to partially finance the Acquisitions; and

 

  Ÿ  

acted as a placement agent in connection with the offering of debt securities by Northern Utilities and Granite State.

 

S-21


Table of Contents

We reimbursed RBC Capital Markets Corporation for approximately $25,000 of expenses incurred in connection with the offering of debt securities by Northern Utilities and Granite State. In addition, in connection with this offering and the offerings in December 2008 and January 2009, we have agreed to reimburse the underwriters for costs, expenses and fees related to qualification under Financial Industry Regulatory Authority regulation, including those of counsel of the underwriters related thereto. We estimate that the total of such costs, expenses and fees will be approximately $12,000.

We intend to use the net proceeds from this offering (including the proceeds from any exercise by the underwriters of their over-allotment option) (i) to repay all amounts outstanding under the bridge credit facility that we used to partially finance the Acquisitions and the related costs and expenses (approximately $39.1 million) and (ii) for other general corporate purposes, including capital contributions to our distribution utilities and repayment of short-term debt.

Because affiliates of RBC Capital Markets Corporation could receive more than 10% of the proceeds of this offering as repayment for amounts outstanding under our bridge credit facility, this offering is made pursuant to the provisions of Section 5110(h) of the National Association of Securities Dealers, Inc. Conduct Rules (which are part of the Financial Industry Regulatory Authority Rules).

In connection with the offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act.

 

  Ÿ  

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

 

  Ÿ  

Over-allotment involves sales by the underwriters of shares in excess of the number of shares the underwriters are obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriters is not greater than the number of shares that they may purchase in the over-allotment option. In a naked short position, the number of shares involved is greater than the number of shares in the over-allotment option. The underwriters may close out any covered short position by exercising their over-allotment option and/or purchasing shares in the open market.

 

  Ÿ  

Syndicate covering transactions involve purchases of the common stock in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. If the underwriters sell more shares than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

 

  Ÿ  

Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.

Table of Contents

We have been advised by the underwriters that, prior to purchasing the shares being offered pursuant to this prospectus supplement, on May 20, 2009, one of the underwriters purchased, on behalf of the syndicate, 8,000 shares at an average price of $20.00 per share in stabilizing transactions.

A prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters or selling group members, if any, participating in this offering. The representatives may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the underwriters and selling group members that will make Internet distributions on the same basis as other allocations.

LEGAL MATTERS

The validity of the shares of the common stock to be sold in the offering will be passed upon for us by Gary Epler, our Chief Regulatory Counsel. As of May 20, 2009, Mr. Epler beneficially owned approximately 3,289 shares of our common stock.

Certain legal matters in connection with the offering will be passed upon for the underwriters by Vinson & Elkins L.L.P., New York, New York.

Table of Contents

The following Unaudited Pro Forma Combined Statement of Earnings has been prepared to give effect to the acquisition (the “Acquisitions”) on December 1, 2008 by Unitil Corporation (“Unitil”) of Northern Utilities, Inc. (“Northern Utilities” or “NU”) and Granite State Gas Transmission, Inc. (“Granite State” or “GS”) as if the businesses had actually been combined as of January 1, 2008.

The Unaudited Pro Forma Combined Statement of Earnings includes adjustments for the Acquisitions pursuant to the purchase method of accounting for business combinations. The Unaudited Pro Forma Combined Statement of Earnings includes adjustments to give effect to:

 

  (i)   the receipt of the estimated net proceeds of approximately $42.1 million from the issuance of 2,000,000 shares of common stock in this offering at an assumed offering price of $22.49 per share, which was the closing price of our common stock on May 13, 2009, and the application of the estimated net proceeds of this offering as described in Use of Proceeds in this prospectus supplement;

 

  (ii)   the issuance of 2,000,000 shares of common stock in December 2008 and 270,000 shares in January 2009, the net proceeds of approximately $41.9 million were used to partially finance the Acquisitions;

 

  (iii)   the sale and issuance in December 2008 by Northern Utilities of $80.0 million aggregate principal amount of long-term unsecured notes; and

 

  (iv)   the sale and issuance by Granite State in December 2008 of $10.0 million aggregate principal amount of long-term unsecured notes;

The Unaudited Pro Forma Combined Statement of Earnings excludes adjustments to recognize:

 

  (i)   estimated annual operating expense savings of $5.6 million (before tax) due to the achievement of efficiencies associated with the provision of shared utility services and the adoption of best practices associated with these shared utility services (excluding the portion of savings realized and included in the twelve months ended March 31, 2009);

 

  (ii)   a reduction in operating expenses of $2.5 million (after tax) related to compliance violation penalties incurred by Northern Utilities, prior to the Acquisitions, in the twelve months ended March 31, 2009;

 

  (iii)   an increase in Gas Operating Revenue of $0.3 million (before tax) and a resulting increase in gross operating margin, related to increased rates authorized by regulators for Granite State; and

 

  (iv)   the enhancements to net income that may occur from the execution of our regulatory plan.

The Unaudited Pro Forma Combined Statement of Earnings assumes that Unitil financed the Acquisitions and the related costs and expenses using the net proceeds from the above-referenced sale and issuance of common stock, the above-referenced sale and issuance of long-term unsecured notes and the financing by Northern Utilities of its gas inventory.

The Unaudited Pro Forma Combined Statement of Earnings is presented for illustrative purposes only and does not indicate the financial results of the combined companies had the companies actually been combined and had the impact of possible net income enhancements, among other factors, been considered, and is not intended to be a projection of future results. The Unaudited Pro Forma Combined Statement of Earnings should be read in conjunction with the notes thereto included in this prospectus.

The following Unaudited Pro Forma Combined Statement of Earnings has been prepared to give effect to the acquisition (the “Acquisitions”) on December 1, 2008 by Unitil Corporation (“Unitil”) of Northern Utilities, Inc. (“Northern Utilities” or “NU”) and Granite State Gas Transmission, Inc. (“Granite State” or “GS”) as if the businesses had actually been combined as of January 1, 2008.

The Unaudited Pro Forma Combined Statement of Earnings includes adjustments for the Acquisitions pursuant to the purchase method of accounting for business combinations. The Unaudited Pro Forma Combined Statement of Earnings includes adjustments to give effect to:

 

  (i)   the receipt of the estimated net proceeds of approximately $42.1 million from the issuance of 2,000,000 shares of common stock in this offering at an assumed offering price of $22.49 per share, which was the closing price of our common stock on May 13, 2009, and the application of the estimated net proceeds of this offering as described in Use of Proceeds in this prospectus supplement;

 

  (ii)   the issuance of 2,000,000 shares of common stock in December 2008 and 270,000 shares in January 2009, the net proceeds of approximately $41.9 million were used to partially finance the Acquisitions;

 

  (iii)   the sale and issuance in December 2008 by Northern Utilities of $80.0 million aggregate principal amount of long-term unsecured notes; and

 

  (iv)   the sale and issuance by Granite State in December 2008 of $10.0 million aggregate principal amount of long-term unsecured notes;

The Unaudited Pro Forma Combined Statement of Earnings excludes adjustments to recognize:

 

  (i)   estimated annual operating expense savings of $5.6 million (before tax) due to the achievement of efficiencies associated with the provision of shared utility services and the adoption of best practices associated with these shared utility services (excluding the portion of savings realized and included in the twelve months ended December 31, 2008);

 

  (ii)   a reduction in operating expenses of $2.5 million (after tax) related to compliance violation penalties incurred by Northern Utilities, prior to the Acquisitions, in the twelve months ended December 31, 2008;

 

  (iii)   an increase in Gas Operating Revenue of $0.4 million (before tax) and a resulting increase in gross operating margin, related to increased rates authorized by regulators for Granite State; and

 

  (iv)   the enhancements to net income that may occur from the execution of our regulatory plan.

The Unaudited Pro Forma Combined Statement of Earnings assumes that Unitil financed the Acquisitions and the related costs and expenses using the net proceeds from the above-referenced sale and issuance of common stock, the above-referenced sale and issuance of long-term unsecured notes and the financing by Northern Utilities of its gas inventory.

The Unaudited Pro Forma Combined Statement of Earnings is presented for illustrative purposes only and does not indicate the financial results of the combined companies had the companies actually been combined and had the impact of possible net income enhancements, among other factors, been considered, and is not intended to be a projection of future results. The Unaudited Pro Forma Combined Statement of Earnings should be read in conjunction with the notes thereto included in this prospectus.

OUR COMPANY

We are a public utility holding company headquartered in Hampton, New Hampshire. We are subject to regulation as a holding company system by the Federal Energy Regulatory Commission (the “FERC”) under the Energy Policy Act of 2005.

Our principal business is the local distribution of electricity and natural gas throughout our service territory in the states of New Hampshire, Massachusetts and Maine. We are the parent company of three wholly owned distribution utilities: (i) Unitil Energy Systems, Inc. (“Unitil Energy”), which provides electric service in the southeastern seacoast and state capital regions of New Hampshire, including the city of Concord, New Hampshire; (ii) Fitchburg Gas and Electric Light Company (“Fitchburg”), which provides both electric and natural gas service in the greater Fitchburg area of north central Massachusetts; and (iii) Northern Utilities, which provides natural gas service in southeastern New Hampshire, including the city of Portsmouth, and portions of southern and central Maine, including the city of Portland. In addition, we are the parent company of Granite State, an interstate natural gas transmission pipeline company that principally provides interstate natural gas pipeline access and transportation services to Northern Utilities in its New Hampshire and Maine service territory.

Our distribution utilities serve approximately 100,300 electric customers and 69,300 natural gas customers in their service territory. Our distribution utilities are local “pipes and wires” operating companies and, combined with Granite State, had an investment in Net Utility Plant of $422.8 million at December 31, 2008. We do not own or operate electric generating facilities or major transmission facilities and substantially all of our utility assets are dedicated to the local delivery of electricity and natural gas to our customers. Our total revenue was $288.2 million in 2008, which includes revenue to recover the cost of purchased electricity and natural gas in rates on a fully reconciling basis. As a result of this reconciling rate structure, our earnings are not affected by changes in the cost of purchased electricity and natural gas. Earnings applicable to common shareholders for 2008 were $9.6 million. Substantially all of our revenue and earnings are derived from regulated utility operations. Our consolidated operating results for 2008 reflect one month of financial activity for Northern Utilities and Granite State, which we acquired on December 1, 2008.

Our business strategy is to be a leader in the reliable and cost effective management of a growing level of local electric and natural gas distribution assets. Our growth initiatives include evaluation of organic growth opportunities as well as strategic acquisitions. As part of our growth strategy, on December 1, 2008, we purchased (i) all of the outstanding capital stock of Northern Utilities from Bay State Gas Company (“Bay State”) and (ii) all of the outstanding capital stock of Granite State from NiSource Inc. (“NiSource”) pursuant to the Stock Purchase Agreement dated as of February 15, 2008 by and among NiSource, Bay State and us. Bay State is a wholly owned subsidiary of NiSource. We refer to these transactions as the “Acquisitions.” The aggregate purchase price for the Acquisitions was $160 million in cash, plus an additional working capital adjustment of $49.2 million, including approximately $30.0 million of natural gas storage inventory. To finance the Acquisitions and recapitalize Northern Utilities and Granite State, we issued additional equity and debt.

A fifth wholly owned subsidiary, Unitil Power Corp. (“Unitil Power”), formerly functioned as the full requirements wholesale power supply provider for Unitil Energy. In connection with the implementation of electric industry restructuring in New Hampshire, Unitil Power ceased being the wholesale supplier of Unitil Energy on May 1, 2003 and divested of substantially all of its long-term power supply contracts through the sale of the entitlements to the electricity associated with those contracts.

We also have three other wholly owned subsidiaries:   Unitil Service Corp. (“Unitil Service”); Unitil Realty Corp. (“Unitil Realty”); and Unitil Resources, Inc. (“Unitil Resources”). Unitil Service provides, at

cost, a variety of administrative and professional services, including regulatory, financial, accounting, human resources, engineering, operations, technology and energy supply management services on a centralized basis to its affiliated Unitil companies. Unitil Realty owns and manages our corporate office in Hampton, New Hampshire. Unitil Resources is our wholly owned non-regulated subsidiary. Usource, Inc. and Usource L.L.C. (collectively, “Usource”) are indirect subsidiaries that are wholly owned by Unitil Resources. Usource provides energy brokering and advisory services to large commercial and industrial customers in the northeastern United States.

RISK FACTORS

Investing in our common stock involve risks. You should carefully consider the risks described in our filings with the SEC referred to in the section entitled Where You Can Find More Information and in the section entitled Cautionary Statement about Forward-Looking Statements, as well as those included in any prospectus supplement hereto. For example, our Annual Report on Form 10-K for the year ended December 31, 2008 contains a discussion of significant risks in the section entitled Risk Factors, which could be relevant to your investment in our common stock. Subsequent filings with the SEC may contain amended and updated discussions of significant risks.

USE OF PROCEEDS

Unless we specify otherwise in the applicable prospectus supplement accompanying this prospectus, we intend to use the net proceeds that we receive from the sale of the common stock covered by this prospectus for general corporate purposes, including repayment of debt, acquisitions, capital expenditures and working capital.

The actual application of proceeds that we receive from the sale of any particular offering of common stock using this prospectus will be described in the applicable prospectus supplement relating to such offering.

DESCRIPTION OF COMMON STOCK

The following description of our common stock summarizes general terms that apply to our common stock. Because this is only a description, it does not contain all of the information that may be important to you. This summary is subject to and qualified in its entirety by reference to our Articles of Incorporation, Articles of Amendment to the Articles of Incorporation and By-Laws. See the section entitled Where You Can Find More Information.

Authorized and Outstanding Shares

Our authorized capital stock consists of 16,000,000 shares of common stock, no par value. As of April 20, 2009, 8,106,155 shares of common stock were outstanding and our subsidiaries, Unitil Energy and Fitchburg, have preferred stock outstanding. Unitil Corporation is not authorized to issue any shares of preferred stock. All of the common stock outstanding is fully paid and nonassessable.

After giving effect to the equity offerings described in this prospectus, approximately 4,443,644 shares of common stock will be available for issuance under our Articles of Incorporation, excluding 450,201 shares reserved for issuance pursuant to our Dividend Reinvestment Plan, our Tax Deferred Savings and Investment Plan, our Restricted Stock Plan, and our 1998 Stock Option Plan. Except in connection with these offerings, our Board of Directors has no immediate plans, intentions, or commitments to issue additional shares of common stock for any purpose, including, without limitation, rendering more difficult or discouraging a merger, tender offer, proxy contest or other change in control of us (collectively referred to as “change in control transactions”). However, the availability of authorized shares of common stock could render more difficult, discourage, or delay a change in control transaction, which may adversely affect the ability of our shareholders to obtain a premium for their shares of common stock. Our Board of Directors is not aware of any pending or proposed change in control transactions.

We will not seek shareholder authorization for issuances of additional authorized shares of common stock unless deemed advisable by our Board of Directors or required by law, rule, or regulation. In some instances, the SEC or stock exchanges or over-the-counter markets on which our securities may then be listed may need to approve such issuances.

Dividend Rights

Holders of our common stock are entitled to those dividends as may be declared from time to time by our Board of Directors. We may pay dividends on our common stock from any funds, property or shares legally available for this purpose.

Voting Rights and Cumulative Voting

Each holder of our common stock is entitled to one vote per share on all matters submitted to a vote of the holders of our common stock. Holders of common stock do not have cumulative voting rights.

Preemptive Rights

The holders of our common stock have no preemptive rights to purchase additional shares of common stock or any other of our securities.

Liquidation Rights

In the event that we are liquidated, after payment of our debts and liabilities, the holders of our common stock are entitled to share equally in the balance of our remaining assets, if any.

Staggered Board of Directors

Our By-Laws provide for a Board of Directors of between nine and fifteen directors divided into three classes, each class being as nearly equal in number as possible, and each with their respective terms of office arranged so that the term of office of one class expires in each year, at which time a corresponding number of directors is elected for a term of three years. We currently have eleven directors.

Our staggered Board of Directors may delay, deter or prevent a tender offer or takeover attempt that a holder of shares of our common stock might consider is in his, her or its best interest, including those attempts that might result in a premium over the market price of the shares of our common stock.

PLAN OF DISTRIBUTION

We may sell our common stock to one or more purchasers, through agents, to or through underwriters or dealers, or through a combination of any such methods of sale. The distribution of our common stock may be effected from time to time in one or more transactions at fixed prices, which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The prospectus supplement will set forth the terms of the offering, including the names of any underwriters, dealers or agents, the purchase price of our common stock and the proceeds to us from such sale, any underwriting discounts and commissions or agency fees and other items constituting underwriters’ or agents’ compensation and any discounts or concessions allowed or paid to dealers or any securities exchange on which such securities may be listed. Any discounts or concessions allowed or paid to dealers may be changed from time to time.

Any discounts, concessions or commissions received by underwriters or agents and any profits on the resale of our common stock by them may be deemed to be underwriting discounts and commissions under the Securities Act of 1933. Unless otherwise set forth in the applicable prospectus supplement, the obligations of underwriters to purchase our offered common stock will be subject to certain conditions precedent, and such underwriters will be obligated to purchase all such common stock, if any are purchased. Unless otherwise indicated in the applicable prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

We may authorize underwriters, dealers or other persons acting as agents for us to solicit offers by certain institutions to purchase our common stock from us, pursuant to contracts providing for payment and delivery on a future date. Institutions with which such contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but in all cases such institutions must be approved by us. The obligations of any purchaser under any such contract will be subject to the conditions that the purchase of the offered common stock shall not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such contracts.

In connection with the offering of our common stock, we may grant to the underwriters an option to purchase additional securities to cover over-allotments at the public offering price, with an additional underwriting commission, as may be set forth in the accompanying prospectus supplement. If we grant any over-allotment option, the terms of such over-allotment option will be set forth in the prospectus supplement for such common stock.

We may indemnify agents, underwriters and dealers against certain liabilities, including liabilities under the Securities Act of 1933. Our agents, underwriters and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.
