Proxy Statement and Notice of 2016 Annual Meeting of Shareholders February 2, 2016 Oshkosh, Wisconsin

Our MOVE strategy We are focused on capturing and improving our historical share in a market recovery. We continue to work on improving sales, inventory, and operations planning and sales capture processes to more effectively respond to customers’ needs. Also, we continue to focus on staying close to our customers by providing high-quality customer service through our extensive parts and service support programs. We are focused on optimizing our cost and capital structure to provide value for customers and shareholders by aggressively attacking product, process and overhead costs and opportunistically using strong free cash flow to return capital to shareholders or invest in acquisition opportunities. We expect to more efficiently utilize our manufacturing facilities; increase inventory turns; reduce product, process and overhead costs; reduce manufacturing lead times and new product development cycle times; and increase operating income margins over the next several years. We seek to expand sales and margins by leading our core markets in the introduction of new or improved products and new technologies. Business development teams actively pursue new customers in targeted countries in Asia, Eastern Europe, the Middle East, Latin America and Africa. In pursuit of this strategy, we opened sales and service offices in recent years in Russia, India, Saudi Arabia, China and Japan to pursue opportunities in each of those countries. In addition, we recently added to our sales and aftermarket personnel in multiple countries in Europe, Latin America, Asia and the Middle East.

Dear Fellow Oshkosh Corporation Shareholder: December 15, 2015 On behalf of our Board of Directors, we thank you for the opportunity to serve you, our shareholders. We know that we are here because you have entrusted us to protect your interests in this business. As we conduct the activities of this Board, we are focused on staying in touch with you. We work with management to listen to your perspectives and to bring those perspectives to our decision making. We would like to highlight several topics that may be of interest to our shareholders: Board composition and shareholder proxy access, compensation, and communication with the Board. Board Composition and Shareholder Proxy Access One of the most important roles for our Board is to ensure that our Board of Directors is comprised of persons with the skills and qualifications necessary to oversee a global business selling highly complex products to diverse customers. For this reason, the issue of Board composition and refreshment is a priority for our Board. Refreshing our Board with new viewpoints and new ideas, while ensuring experienced Directors continue to bring their perspectives, is critical to our success. Since 2010, eight new Directors have been elected to our Board and all of our Board Committees have new members and new Chairs. Two of those new Directors were added since July of this fiscal year, and Wilson Jones, Mr. Szews’ successor as CEO, will join the Board on January 1, 2016. Throughout this time, we have also benefited from the highly-informed counsel of our Directors with longer tenures. We encourage you to review the skills and qualifications of our nominees for the Board of Directors. We think you will be impressed by them both individually and as a group with vast experiences and diversity of backgrounds that contribute to their strength as a Board. We expect to continue to see the benefits of refreshment of our Board as new, highly capable, diverse members join the Board in future years. As noted, we value our shareholders’ views and appreciate their guidance on key issues. In particular, we have been evaluating proxy access and how best to enhance our shareholders rights in this regard. After listening to our shareholders, we learned that there are many different views on this topic. We carefully collected those perspectives and proactively developed and adopted a by-law that we believe fully addresses concerns we heard and that will protect the long-term interests of all our shareholders. We believe this is an important and positive governance initiative. Compensation Our compensation programs are structured to pay for performance. While we achieved solid results in fiscal year 2015 in the face of tough market conditions and built a foundation for future growth, we did not meet our consolidated operating income target which is directly reflected in lower incentive compensation earned in fiscal year 2015 for our executives and participating employees. OSHKOSH CORPORATION 2015 Proxy Statement

It should be noted that, in fiscal year 2012, Mr. Szews asked not to be granted a performance share award to help manage operating expenses and help ensure appropriate equity compensation awards could be used for retention of a talented team during that difficult time. As a result of that decision, Mr. Szews did not receive any payout under that program in fiscal year 2015. Meaningful dialogue with our shareholders has reaffimed our belief that our compensation programs are sound and appropriately reward employees for producing strong results, consistent with the Company’s strategy. We are particularly pleased that the shareholders’ advisory vote last year on our executive compensation was 97% favorable. Communications with the Board The Board is committed to engaging with shareholders and encourages an open dialogue about topics of interest to our shareholders. We value your input, your investment and your support. You are welcome to contact the Board, in care of the Office of the Secretary, Oshkosh Corporation, 2307 Oregon Street, Post Office Box 2566, Oshkosh, WI 54903-2566. Your trust and confidence are very much appreciated. Sincerely, Charles L. Szews Chief Executive Officer Richard M. Donnelly Chairman of the Board OSHKOSH CORPORATION 2015 Proxy Statement

If this is the case, you should have received the Notice of Internet Availability of Proxy Materials and a voting instruction form from your broker, bank or other nominee.

SummARy INfORmATION | Business Highlights Since fiscal year 1997, our sales and operating income have grown at compound annual growth rates of 12.9% and 15.7%, respectively. Although U.S. Defense spending has steadily declined over the last few years, leading to a significant downturn in what historically was our largest segment, Defense, we are successfully executing on our MOVE strategy, our Company’s roadmap for driving performance and creating value for shareholders. While we did not achieve our September 2012 Analyst Day targets for EPS in fiscal year 2015, we outperformed many of our peers over this period and delivered solid adjusted EPS of $3.021 in fiscal year 2015, representing an approximate compound annual growth rate of 10% from adjusted EPS of $2.301 in fiscal year 2012. We achieved this as we endured a sharp downturn in U.S. Defense spending that caused our Defense sales to fall from $3.95 billion in fiscal year 2012 to $940 million in fiscal year 2015. We also weathered a mid-cycle dip in access equipment demand beginning in our third quarter of fiscal year 2015. Importantly, we believe we set the foundation in fiscal year 2015 for our Defense business to contribute significantly higher earnings beginning in fiscal year 2016. We have been actively expanding the number of variants of our Mine Resistant Ambush Protected All Terrain Vehicle (M-ATV) and marketing them to global allies. In fiscal year 2016, we expect to sell approximately 1,000 additional M-ATVs. Further, we continue to pursue opportunities to sell thousands of additional M-ATVs over the next several years. Also, the historic award of the $6.7 billion U.S. Joint Light Tactical Vehicle (JLTV) contract in August 2015 strengthens our long-term outlook for the Company. The Oshkosh JLTV provides a leap forward in tactical wheeled vehicle performance for our brave men and women in uniform, and we are honored to continue to serve them. We believe the JLTV award provides a strong, long-term growth catalyst for Oshkosh’s Defense business, both domestically and for international markets. Not only did we set a strong foundation for our Defense business in fiscal year 2015, we also sustained both revenue growth and margin improvement in our Fire & Emergency and Commercial segments in fiscal year 2015. Overall, our MOVE strategy continued to deliver margin enhancement. (1) This Proxy Statement includes non-GAAP results.

SummARy INfORmATION | The Four Key Components of Our MOVE Strategy are: THE FOUR KEY COMPONENTS OF OUR MOVE STRATEGY ARE: We are focused on capturing and improving our historical share in a market recovery. While our markets have experienced some recovery in recent years, the recovery has been slower than anticipated. We continue to work on improving sales, inventory, and operations planning as well as sales capture actions to more effectively respond to customers’ needs. Also, we continue to focus on staying close to our customers by providing high-quality customer service through our extensive parts and service support programs. Market Recovery and Growth We are focused on optimizing our cost and capital structure to provide value for customers and shareholders by aggressively attacking product, process and overhead costs and using strong free cash flow to opportunistically return capital to shareholders or invest in acquisition opportunities. Our customer-centric Oshkosh Operating System (OOS) provides the framework for our lean enterprise approach that allows us to deliver premium product features, high quality and low product life cycle costs for customers. Despite numerous headwinds, we significantly exceeded our target for fiscal year 2015 of improving the Company’s operating income margin by 250 basis points compared to fiscal year 2012. Additionally, we repurchased 4.9 million shares or 6.1% of our outstanding shares in fiscal year 2015, signaled additional share repurchases in fiscal year 2016 and increased our dividend rate 12% in November 2015. Optimize Cost and Capital Structure We seek to expand sales and profit margins by leading our core markets in the introduction of new and improved products and new technologies. In fiscal year 2015, we accelerated the pace of new product launches, allowing us to deliver more than our goal of $350 million of incremental annual revenue from new product launches compared to fiscal year 2012. Value Innovation We expect to grow our international business and in 2012 set a target of 25% of our revenues from international markets by fiscal year 2015. We did not achieve that target primarily due to weaker global markets and the strong U.S. dollar which caused our growing international sales to translate into fewer U.S. dollars and reduced the competitiveness of our exports. However, we have realized success as we actively pursue new customers in targeted countries in Asia, Eastern Europe, the Middle East, Latin America and Africa. In pursuit of this strategy, we opened sales and service offices in recent years in Russia, India, Saudi Arabia, China and Japan to pursue opportunities in each of those countries. We have expanded our international sales of M-ATVs. 21% (23% on a constant currency basis) of our revenues came from sales outside of the United States in fiscal year 2015, compared to 21.8% in fiscal year 2012.

SummARy INfORmATION | Effective Execution of Our MOVE Strategy Under Difficult Conditions. EFFECTIVE EXECUTION OF OUR MOVE STRATEGY UNDER DIFFICULT CONDITIONS. In fiscal year 2015, the Company faced two difficult conditions. First, the multi-year decline in U.S. Defense spending caused our Defense sales and earnings to fall to trough, marginally profitable levels, consistent with our expectations. However, we did not anticipate a broad-based decline in construction equipment sales in North America during a period of improving residential and nonresidential spending. This decline in fiscal year 2015 was caused by a number of contributing factors including severe weather in the northeastern U.S. and rains across the southern U.S. which shortened the construction season and a decline in oil and gas construction activity. This led to sales declines in our access equipment and concrete mixer businesses in the second half of our fiscal year which impacted our ability to achieve our long-term target for fiscal year 2015 EPS. Despite these difficult conditions, we delivered solid results in fiscal year 2015 and believe we set the foundation for improved earnings performance in fiscal year 2016. Highlights of our fiscal year 2015 performance include: • Exercised prudent capital allocation. We sustained smart capital allocation by repurchasing 4.9 million shares or 6.1% of our outstanding shares in fiscal year 2015 and announcing a 12% dividend increase effective in November 2015 consistent with our goal of increasing the dividend at a double digit rate across the economic cycle. We expect to fund further share repurchases and cash dividends in fiscal year 2016 through a combination of expected cash flow from operations and cash on hand. Since 2012, when we launched our MOVE strategy, we have returned more than $900 million in cash to shareholders through share repurchases and cash dividends, including the repurchase of more than 20 million shares of our common stock, representing approximately 21% of our shares. Delivered higher sales and margins in our Fire & Emergency and Commercial segments. Due largely to market share gains, in marginally improving markets, we grew sales by 7.8% and 12.9% in our Fire & Emergency and Commercial segments, respectively, in fiscal year 2015. Importantly, by executing our strategic growth roadmaps for each segment, we increased the operating income margins of those segments by 190 and 40 basis points, respectively, which yielded a combined 35% increase in the operating income of these two segments. The improvement in Commercial segment operating income margin was muted by investments intended to raise margins further in fiscal year 2016. Set foundation for Defense segment earnings recovery in fiscal year 2016. As a result of extensive efforts over multiple years expanding the number of M-ATV variants and marketing them globally, we expect to sell approximately 1,000 M-ATVs in fiscal year 2016. Further, we continue to pursue opportunities to sell thousands of additional M-ATVs over the next several years. Achieved historic award of JLTV contract. We believe the historic award of the $6.7 billion JLTV contract positions our Defense business for strong performance over the next eight years. The JLTV will become the tactical workhorse for transporting the next generation of U.S. soldiers and Marines on the battlefield. Advanced deployment of the Oshkosh Operating System. During the past three years, we provided foundational training for more than 11,000 employees and contractors in elements of OOS. We believe OOS provides us with the tools to deliver on our growth roadmap and will continue to do so for the foreseeable future as our customer-first culture becomes more deeply ingrained in our Company. • • • • We believe Oshkosh is positioned to perform well for all stakeholders over the next few years. There will be challenges, and we expect a soft start to fiscal year 2016, but overall we expect to grow earnings and cash flow in fiscal year 2016 and have a positive long-term outlook. We believe Oshkosh has leading brands in all our markets and excellent long-term prospects. Our Defense portfolio, which now includes the JLTV and new M-ATV variants, is experiencing growing global demand due to ongoing conflicts and emerging threats. We expect increased penetration of access equipment in developing global markets and sustained construction growth in North America to lead to solid years ahead for JLG, the global leader in access equipment. And, our Fire & Emergency and Commercial segments have realistic growth roadmaps. The segments work well together to leverage procurement, technology and customer synergies and should remain leaders in their markets. With the evolution of the MOVE strategy and Oshkosh Operating System, Oshkosh has created an innovative, continuously improving culture focused on serving and delighting customers. This should lead to greater levels of customer satisfaction and further margin enhancement. * * * * OSHKOSH CORPORATION 2015 Proxy Statement 8

Proposal 1 ELECTION OF DIRECTORS BACKGROUND TO BOARD’S RECOMMENDATION FOR DIRECTOR NOMINEES Board composition, refreshment and diversity are priorities for our shareholders as well as for our Board. Our Board will seek to provide orderly refreshment of the Board while sustaining strong board composition and diversity. We define diversity broadly, to include the personal attributes of the individual directors as well as their various careers, areas of expertise and their tenure on the Board. Our Board continues to review the size of the board and its composition to accommodate outstanding candidates while retaining the balance of skills and attributes needed to oversee our Company’s complex, global operations. On September 15, 2015, Charles L. Szews, our current Chief Executive Officer and a member of our Board of Directors, notified our Company of his intent to retire from each of these positions effective December 31, 2015. As a result of Mr. Szews’ intention to retire as Chief Executive Officer, on the same day the Board acted to elect Wilson R. Jones, our current President and Chief Operating Officer, as Chief Executive Officer effective January 1, 2016. The Board also acted to elect Mr. Jones as a member of the Board, effective January 1, 2016, to fill the vacancy created by Mr. Szews’ retirement from the Board. As a result, Mr. Jones will serve in a dual role as President and Chief Executive Officer effective January 1, 2016 and will also serve as a member of the Board commencing that date. Mr. Jones’ initial term on the Board expires as of the 2016 Annual Meeting, when he is a nominee for re-election to the Board. Since her election to our Board in 1997, our Company has benefitted from the wisdom and expertise Ms. Kathleen J. Hempel has brought to our Board. Ms. Hempel is not standing for re-election and our Board decided to reduce its size from the current thirteen members to twelve members, effective at the Annual Meeting. The Board has selected twelve nominees for election at the 2016 Annual Meeting to hold office until the next Annual Meeting and the election of his or her successor. Eleven are current directors, and Mr. Jones, as noted above, will be a director at the time of the 2016 Annual Meeting. Each nominee has agreed to be named in this Proxy Statement and to serve on the Board of Directors if elected. With the exception of Mr. Jones, our incoming President and Chief Executive Officer, all nominees for the Board are independent as defined by New York Stock Exchange (NYSE) listing standards. Since 2010, we have added eight independent directors who have brought valuable and varied experience in distinct and critical areas of our businesses, each providing a fresh perspective on our Board. In 2010 and 2011, we enhanced our Board’s defense industry expertise by electing Gen. (Ret.) William S. Wallace and Lt. Gen. (Ret.) Leslie F. Kenne, who served in the United States Army and Air Force, respectively. In 2011, we elected Peter B. Hamilton and Duncan J. Palmer, each of whom brings an extensive financial background as a former Chief Financial Officer of a publicly-traded company. In 2012, our shareholders elected John S. Shiely, the former Chairman and Chief Executive Officer of Briggs & Stratton Corporation. Mr. Shiely brings extensive public company leadership experience as well as legal and administrative experience to our Board. In 2013, our shareholders elected Stephen D. Newlin, then Chairman, President and Chief Executive Officer of PolyOne Corporation. Among other attributes, Mr. Newlin brings extensive knowledge and experience with respect to international issues to our Board. Most recently, the Board elected Steven C. Mizell, who brings extensive experience in human resources and international matters, and Keith J. Allman, who is a seasoned business leader with chief executive officer experience leading strategy development and implementation and process improvement initiatives on a global basis. Effective January 1, 2016, Mr. Jones will become President and Chief Executive Officer and be elected to the Board of Directors. Mr. Jones brings strong leadership skills with a deep understanding of our customers, products and markets. To complement these more recently elected directors, the nominees include tenured directors who have experienced the economic and defense business cycles faced by our Company, as well OSHKOSH CORPORATION 2015 Proxy Statement 10

Effective on election at our 2015 Annual Meeting of Shareholders, we granted to each of our then non-employee directors 2,875 shares of our Common Stock under the Oshkosh Corporation 2009 Incentive Stock and Awards Plan. The stock awards were at the 50th percentile of the Towers Watson data for non-employee director compensation. On their election to the Board, Mr. Allman was granted 1,375 shares our Common Stock and Mr. Mizell was granted 1,825 shares. Deferred Compensation Plan Non-employee directors may elect to participate in our Deferred Compensation Plan for Directors and Executive Officers. This plan permits individual directors to defer any or all of their compensation from Oshkosh, including their stock awards. A director who defers fees may elect to have deferred amounts credited to a fixed-income investment account or a stock account. Deferrals of stock awards must be credited to a stock account. Deferrals credited to a fixed-income investment account earn interest at the prime rate as published in The Wall Street Journal on the last business day of the immediately preceding plan year quarter, plus 1%. Deferrals credited to a stock account are treated as though invested in our Common Stock. Any dividends earned on our Common Stock are reinvested in each director’s stock account. Payments from the Deferred Compensation Plan may be made in a lump sum or in annual installments for up to ten years at the election of the director. Payments generally commence when a director ceases to be a member of our Board. In the event of a change in control of our Company, as defined in the Deferred Compensation Plan, we will pay out the accounts of all directors in a single lump sum cash payment. Stock Ownership Guidelines for Directors The Human Resources Committee has adopted stock ownership guidelines for non-employee directors to ensure that non-employee directors have a direct stake in the success of our Company. Under these guidelines, non-employee directors are encouraged to acquire and own our Common Stock in an amount equal to five times their respective annual cash retainers. Non-employee directors should achieve this stock ownership level within five years of becoming a director. As of November 20, 2015, all directors, except Mr. Allman, Mr. Mizell, and Mr. Newlin, who have served as directors for less than five years, met the requisite stock ownership levels. Mr. Szews is subject to the stock ownership guidelines that apply to our executive officers. As of November 20, 2015, Mr. Szews exceeded the stock ownership level applicable to him as Chief Executive Officer. Our Company has a policy that prohibits directors and all officers from entering into certain transactions for their individual accounts, including hedging or pledging our Common Stock and trading in puts, calls or other derivative securities relating to the Common Stock.

Governance of the Company Board of Directors Independence With the exception of incoming President and Chief Executive Officer Mr. Jones, all of the nominees for election to our Board are independent. The Board has determined that no non-employee director nominee has a material relationship with our Company and that all are independent under NYSE listing standards. Further, no director or executive officer has any family relationship with any other director or executive officer. Meetings of the Board of Directors The Board of Directors met five times during fiscal year 2015. Each director nominee attended all of the meetings of the Board occurring while he or she was a director and no less than 75% of all Committee meetings. The Board expects directors to attend the Annual Meeting of Shareholders. All of our directors attended our 2015 Annual Meeting, either in person or by phone or video conference, and we anticipate that all director nominees will attend the Annual Meeting in person this year. Our independent, non-employee directors met in executive session, without the presence of our officers, on five occasions during fiscal year 2015. Mr. Donnelly, the independent Chairman of the Board, presided over all executive session meetings of the non-employee directors. Shareholder Engagement and Say-on-Pay Our shareholders are key participants in the governance of our Company. For this reason, we spend time meeting with our shareholders, listening to their concerns, and responding to their feedback. During fiscal year 2015, members of the management team travelled extensively to meet with shareholders and potential shareholders. Our management also proactively reached out to shareholders following our release of quarterly earnings. During these candid meetings, we discussed our Company’s performance and our MOVE strategy, and heard shareholder feedback on a variety of topics. We know that executive compensation is among the many issues important to shareholders. The Board is particularly gratified that, at our 2015 Annual Meeting, approximately 97% of the votes cast were in favor of the advisory proposal to approve the compensation of our named executive officers. Communicating with the Board of Directors We encourage you to share your opinions, interests, concerns, and suggestions. If you would like to communicate with the Chairman or with the Board as a whole, you may send correspondence to the Secretary, Oshkosh Corporation, 2307 Oregon Street, P.O. Box 2566, Oshkosh, Wisconsin 54903-2566. Your correspondence will be forwarded to the Board or the appropriate committee, as applicable. Committees of the Board of Directors Our Board of Directors has three standing committees: the Audit Committee, the Governance Committee, and the Human Resources Committee. The members and responsibilities of these committees as of the date of the Notice of Annual Meeting of Shareholders are set forth below. The Board has determined that each member of each committee is an independent director as defined under NYSE listing standards and SEC rules, including rules specifically pertaining to members of audit committees and compensation committees.

Selection of Nominees for Election to the Board and Consideration of Shareholder-Recommended Candidates The Governance Committee will consider candidates for nomination as a director recommended by shareholders, directors, officers, third-party search firms, and other sources, and reviews all candidates in the same manner, regardless of the source of the recommendation. In evaluating candidates, the Governance Committee considers the needs of the Board and attributes of the individual candidates, including character, judgment, career specialization, relevant technical skills or financial acumen, diversity of viewpoint, and industry knowledge. The Board and the Governance Committee believe director candidates should possess the following minimum qualifications: (i) the highest personal and professional ethics, integrity and values; (ii) the ability to make independent analytical inquiries and to exercise sound business judgment; OSHKOSH CORPORATION 2015 Proxy Statement 23 THE GOVERNANCE COMMITTEE: MEMBERS: THE AUDIT COMMITTEE: MEMBERS:

In addition, the Board and the Governance Committee believe at least one director should have the requisite experience and expertise to be designated an “audit committee financial expert” as defined by applicable SEC rules. Any shareholder who wishes to recommend a director candidate must provide written notice to the attention of our Secretary at the address shown on the Notice of Annual Meeting of Shareholders. Such notice must include the shareholder’s name and address; the class and number of shares of Common Stock owned; the name, age, business address, and principal occupation of the candidate; and the number of shares of Common Stock owned by the candidate, if any. The notice also must include the information that would be required to be disclosed in the solicitation of proxies for election of directors under the federal securities laws. We may require any candidate to furnish additional information, within reason, to determine the candidate’s eligibility. A shareholder wishing to nominate a candidate for election as a director also must comply with the provisions of our by-laws described under “Additional Information Regarding the Annual Meeting — Shareholders Intending to Present Business at the 2017 Annual Meeting”. Diversity on the Board Our Corporate Governance Guidelines have long provided that our Board is committed to a diversified membership. Our Board defines diversity broadly, to include the personal attributes of the individual directors as well as their various careers and areas of expertise and their tenure on the Board. As part of its process of identifying potential nominees, the Governance Committee considers the attributes of existing directors and directs the third-party executive search firm that assists in identifying candidates to search for individuals who would contribute to diversity. As part of its annual self-evaluation, the Governance Committee assesses the effectiveness of its efforts to attain diversity by considering whether it has an appropriate process for identifying and selecting director candidates.

In addition, pursuant to SEC rules and NYSE listing standards regarding the independence of compensation committee advisers, the Human Resources Committee has the responsibility to consider the independence of Towers Watson. The Human Resources Committee reviewed the independence of Towers Watson and its individual representatives who serve as consultants to the Human Resources Committee and concluded that Towers Watson is independent and that Towers Watson’s performance of services raises no conflict of interest. We provide additional information regarding the Human Resources Committee and our policies and procedures regarding executive compensation below under “Executive Compensation — Compensation Discussion and Analysis”. Corporate Governance Documents We make the following governance-related documents available on the Corporate Governance page under the “About Oshkosh” tab on our website, www.oshkoshcorporation.com: • • Our Corporate Governance Guidelines The written charters of the Audit Committee, the Governance Committee, and the Human Resources Committee of our Board of Directors The Oshkosh Corporation Code of Ethics Applicable to Directors and Senior Executives, which applies to all officers at the vice president level or higher The Corporate Code of Ethics and Standards of Conduct, known as “The Oshkosh Way”, which applies to all of our employees • • Each such document also is available in print to any shareholder who requests it from our Secretary. Policies and Procedures Regarding Related Person Transactions As described above, our Board of Directors adopted the Oshkosh Way for all employees. Our named executive officers are also required to acknowledge in writing that they have received, reviewed and understand the requirements of the Code of Ethics, and further acknowledge that failure to fully comply with the Code of Ethics can subject them to discipline, up to and including removal from our Board of Directors or termination of employment. The Oshkosh Corporation Code of Ethics requires the prompt disclosure to our Chief Ethics and Compliance Officer, General Counsel or the Chair of the Audit Committee of any proposed transaction or relationship that could create or appear to create a conflict of interest for their review and recommended action which can range from closing the file to review with the Board of Directors. Under the Code of Ethics, the phrase “conflict of interest” is broadly construed to include direct conflicts, indirect conflicts, potential conflicts, apparent conflicts, and any other personal, business or professional relationship or dealing that has a reasonable possibility of creating even the mere appearance of impropriety. The Code of Ethics also prohibits directors and senior executives from taking personal advantage of business opportunities that we typically would pursue or in which we may be interested. There is a firm bias against waivers of these restrictions. Oversight of Risk Management by the Board of Directors The Board is responsible for general oversight of our risk management. The Board focuses on the most significant and material risks facing our Company and ensures that management develops and implements controls and appropriate risk mitigation strategies. The Board responds to particular risk management issues as part of its general oversight of our Company and in connection with its review and approval of corporate matters. The Board has delegated many of its responsibilities for oversight of our risk management program to the Audit Committee. The Audit Committee evaluates and discusses overall guidelines, policies, processes, and procedures with OSHKOSH CORPORATION 2015 Proxy Statement 25

Governance of the company | respect to risk assessment and risk management. Our Organization Risk Management program, or ORM Program, identifies potential exposure to risks, including strategic, operational, financial, knowledge, cyber security, information technology, and legal and regulatory compliance risks. Senior management is responsible for the administration of the ORM Program. To that end, management assesses and evaluates potential risks for each of our business segments and our Company as a whole, and then develops mitigation strategies to address these potential risks. Senior management reviews and prioritizes risk assessments and mitigation strategies and reports to the Audit Committee risk management results to effectively manage our risk profile. The Audit Committee then considers and discusses these reports. Additionally, senior management and the Audit Committee report to the Board on material risk assessments and mitigation strategies as part of the strategic plan updates they give to our Board during the fiscal year. The ORM Program is designed to: (i) provide the Audit Committee with an assessment of our potential exposure to material risks; (ii) inform the Audit Committee as to how senior management addresses and mitigates potential material risks; and (iii) allow the Audit Committee to evaluate how these risks may affect performance, operations and strategic plans and to ensure that senior management is implementing effective mitigation strategies as necessary. We believe our ORM Program provides an effective approach for addressing potential risks and enables the Audit Committee and the Board to fulfill their general risk oversight functions. In addition to the ORM Program, each Board committee routinely monitors the various risks that fall under the committee’s area of responsibility. Each committee routinely reports on its actions to the full Board. This coordination of risk management allows the Board and the committees to effectively manage risk oversight, especially with regard to interrelated risks. Independent Chairman of the Board Under our by-laws and Corporate Governance Guidelines, our Chairman of the Board must be a director who the Board has determined is independent in accordance with the listing standards of the NYSE and cannot have previously served as an executive officer of our Company. As a result, separate individuals serve as Chairman of the Board and Chief Executive Officer. We believe this leadership structure fosters effective governance and oversight of our Company by: (i) providing the independent directors with control over the Board meeting agenda and discussion; (ii) assuring that independent directors control discussions about strategic alternatives; (iii) enabling an effective assessment of the Chief Executive Officer’s performance; (iv) providing an effective means for the Board to express its views on management, strategy and execution; and (v) positioning the Chairman to obtain direct and meaningful feedback from shareholders. Majority Voting for Director Elections We have a form of majority voting for directors. In the absence of a contested election, any nominee for director who receives a greater number of votes “withheld” from his or her election than votes “for” such election must promptly tender a resignation to the Chairman of the Board. The Governance Committee (or, under certain circumstances, another committee appointed by the Board) will promptly consider the matter and will recommend to the Board whether to accept or reject the tendered resignation based on all relevant factors. The Board must act on that recommendation no later than 90 days after the Annual Meeting of Shareholders at which the election took place. The Board’s decision, including a full explanation of the process by which the decision was reached and, if applicable, the reasons for rejecting the resignation, will be disclosed in a Current Report on Form 8-K filed with the SEC. Succession Planning The Human Resources Committee, in conjunction with the Chief Executive Officer, reviews a comprehensive management succession plan each year. The plan identifies potential successors for each executive position; prior year accomplishments in preparing successors; and current development needs. The preparation and orderly transition of Mr. Jones as Mr. Szews’ successor and the planning and development of a successor for Mr. Jones for the position of Chief Executive Officer are critical to the Human Resources Committee. The transition from Mr. Szews to Mr. Jones was greatly facilitated by the Board’s promotion of Mr. Jones to the role of President and Chief Operating Officer in fiscal year 2012, a position that offered exposure to all businesses and corporate functions and presented the opportunity to work directly with Mr. Szews on all matters of material importance to our Company. In addition, Mr. Jones has had frequent, direct engagement with the Board and Oshkosh shareholders. OSHKOSH CORPORATION 2015 Proxy Statement 26

The Audit Committee will consider annually and, if appropriate, approve the provision of audit services by our independent registered public accounting firm and consider and, if appropriate, pre-approve the provision of certain defined audit and non-audit services. The Audit Committee will also consider on a case by case basis and, if appropriate, approve specific engagements that are not otherwise pre-approved.

Beneficial ownership also includes shares the directors and executive officers have a right to acquire within 60 days after November 20, 2015, as, for example, through the exercise of a stock option. Except as otherwise stated in the footnotes to the following table, information about Common Stock ownership is as of November 20, 2015. The percent of Common Stock beneficially owned is based on the number of shares outstanding on the record date for the Annual Meeting. At the close of business on December 11, 2015, the record date for the Annual Meeting, there were 73,097,878 shares of Common Stock outstanding. Our policies prohibit directors or named executive officers from pledging shares.

Compensation Discussion and Analysis EXECUTIVE SUMMARY Introduction and Overview This Compensation Discussion and Analysis explains our compensation programs and policies for fiscal year 2015 and details the compensation decisions that we made with respect to our Named Executive Officers, or NEOs. For fiscal year 2015, our NEOs identified in the Summary Compensation Table consist of our Chief Executive Officer (CEO), our Executive Vice President (EVP) and Chief Financial Officer (CFO) and the next three highest compensated Executive Officers serving as such at fiscal year-end. The following provides details on how our NEOs were compensated for fiscal year 2015 (October 1, 2014 through September 30, 2015) and how their fiscal year 2015 compensation aligns with our pay for performance philosophy. Business Highlights We are executing our roadmap for creating value for shareholders while driving to overcome a significant downturn in U.S. Defense spending impacting our Defense segment, which at one time was our largest segment. In fiscal year 2015, our primary focus was to continue executing our MOVE strategy across all of our businesses, as we describe in detail in this Proxy Statement under “Summary Information — Business Highlights — Our MOVE Strategy”. The goal of our MOVE strategy was to nearly double earnings per share from fiscal year 2012 to fiscal year 2015 despite the expected decline in Defense segment earnings of more than 90%. We performed well under this strategy in fiscal years 2014 and 2013, in each year exceeding our earnings per share targets for those years. We believed we were on track to achieve our fiscal year 2015 target to approximately double fiscal year 2012 earnings per share when severe weather in the Northeast U.S., rains across the Southern U.S. and a sharp decline in the price of oil and gas contributed to a mid-cycle dip in access equipment demand that began in our third quarter of fiscal year 2015. While we did not achieve our original EPS target for fiscal year 2015, we grew adjusted EPS from fiscal year 2012 to fiscal year 2015 at a compound annual rate of approximately 10%. Oshkosh was awarded the JLTV contract on August 25, 2015. This is an historic contract for our Company. The initial requirements of the eight year, $6.7 billion contract call for us to provide approximately 17,000 vehicles to the U.S. Army and U.S. Marine Corps with a total estimated program requirement of 55,000 vehicles over 20+ years. Additionally, we deployed a prudent capital allocation strategy, which involved the repurchase of 4.9 million shares of our Common Stock in fiscal year 2015 for $200 million, and on October 29, 2015, we announced a 12% increase in our quarterly cash dividend, further demonstrating our commitment to exercise sound capital allocation. Pay for Performance A fundamental principle underlying our compensation program is that we should pay for performance. While our performance was solid in the face of tough market conditions in fiscal year 2015, and management set the foundation for improved results in fiscal year 2016, our Company’s performance did not meet our high expectations. This performance is directly reflected in the sharply lower incentive compensation payouts for fiscal year 2015 for our corporate management team and our underperforming segments. Our compensation program for fiscal year 2015 supported performance by providing appropriate incentives to our executives. To prudently manage our compensation expense while still attracting and retaining the highest caliber executives, we generally target base salary and other elements of compensation close to the 50th percentile for the companies represented in relevant databases, as discussed below. Our annual cash incentive compensation payouts for fiscal year 2015 are based solely on performance relative to three objective measures: consolidated operating income (OI), consolidated return on invested capital (ROIC) and, for Mr. Urias and Mr. Johnson, operating income for their respective segments. Our equity-based long-term incentive awards, which by their nature tie compensation directly and objectively to performance, help ensure that our executives’ interests are aligned with those of our shareholders. Overall, we allocate a greater portion of NEO compensation to pay that varies based on Company and segment performance (annual incentive and long-term equity incentives) than we do to fixed compensation (base salary and benefits). Benefits that are not available to Oshkosh employees generally are limited and related to business need. OSHKOSH CORPORATION 2015 Proxy Statement 31

COMPENSATION DISCUSSION AND ANALYSIS | Oversight of the Human Resources Committee Say-on-Pay and Changes to Fiscal Year 2016 Compensation At our 2015 Annual Meeting, shareholders voted strongly in favor of our executive compensation program. Specifically, more than 97 percent of the shares voted were in favor of the advisory vote on the compensation of our named executive officers. Despite this high level of support from our shareholders, we continue to review our programs and refine them to ensure alignment with our shareholders’ interests. For fiscal year 2016, we have revised the performance measurements in our annual cash incentive awards for corporate NEOs by using Free Cash Flow rather than Return on Invested Capital for 30 percent of the target award. Consolidated Operating Income will remain as a performance measurement for 70 percent of their target award. Our shareholders recognized Free Cash Flow as a key indicator of our business success during various shareholder outreach programs and expressed an interest in higher Free Cash Flow generation by the Company. Accordingly, for fiscal year 2016, we instituted the Free Cash Flow performance measure as part of our annual incentive plan to enhance focus on improving Free Cash Flow and to align incentive compensation with shareholders’ feedback. For our segment presidents for fiscal 2016, we maintained Consolidated Operating Income and Segment Operating Income as measurements in the annual incentive plan at 30 percent and 50 percent of the target award, respectively. We still believe it is important to provide business segment presidents the opportunity to be rewarded for results primarily tied to their business segment. The remaining 20% of the target award for business segment presidents will be tied to a Days Net Working Capital Improvement (DNWCI) measurement. Similar to the Free Cash Flow measurement for our corporate NEOs, DNWCI provides important focus on substantially improving Free Cash Flow for our Company. In the interest of maintaining an emphasis on attaining strong earnings on invested capital, we have repurposed the Return on Invested Capital (ROIC) measurement by adding it to our mix of long-term incentives as a performance-based measure for performance shares. ROIC will continue to be a relative performance measure, requiring our Company performance to exceed certain thresholds relating to a peer group of companies. We also maintained relative total shareholder return as a performance-based measure for performance shares for a combined weight of 30 percent of the target award. The remainder of the long-term incentive measures remained the same: stock options at 30 percent and restricted stock units at 40 percent of the target award, respectively. HUMAN RESOURCES COMMITTEE OVERSIGHT RESPONSIBILITIES The Human Resources Committee establishes, oversees and approves the compensation programs, awards, practices and procedures for our executive officers. The Committee makes annual compensation decisions in a thoughtful and deliberate process based on open discussion and competitive market data provided by an independent compensation consultant. The Committee also recommends to the Board of Directors the competitive pay package for its directors. COMPENSATION PHILOSOPHY AND OBJECTIVES The objectives of our executive compensation programs are to link pay to performance and to attract, retain and motivate executives. The Committee strives to clearly align incentive compensation opportunities with the long-term interests of our shareholders. As a result, our compensation programs are designed to reward executives for annual financial results as well as strategic decision-making for sustained long-term Company performance. We mitigate compensation risks by having incentive plan caps, defined financial performance measures, multiple approval review gates, and a compensation clawback policy. We annually complete a thorough risk analysis of our compensation programs. OSHKOSH CORPORATION 2015 Proxy Statement 32

COMPENSATION DISCUSSION AND ANALYSIS | Annual Compensation Plans Design Review Consistent with the objectives of our compensation program, the Committee has designed cash and equity awards that have varying time frames for earning and payment and include a substantial proportion of pay that is “at risk” and dependent on future performance. The primary components of our executive compensation program in fiscal year 2015 were as follows: For More Information, See Page Type of Compensation Specific Compensation Component Key Features For Fiscal 2015 Fixed Base salary We generally set base salary within 15% of the 50th percentile of the relevant database; we base increases on performance and market competitiveness 34 Performance-based short-term incentive Annual cash incentive awards We base these awards on the achievement of challenging annual performance goals 34-37 Performance-based long-term incentive Stock options Stock options tie a portion of the recipient’s compensation to share price appreciation over a period of up to seven years 37 Performance shares Performance shares benefit the recipient if our Total Shareholder Return over a period of three years compares favorably to Total Shareholder Return among companies in our peer group 38 Restricted stock units Restricted stock ties a portion of the recipient’s compensation to share price appreciation over a period of up to three years 39 ANNUAL COMPENSATION PLANS DESIGN REVIEW The Committee annually evaluates our compensation plans to determine if it is appropriate to adjust plan design, types of awards, or levels of pay. This evaluation includes a review with our independent compensation consultant, Towers Watson, and its analysis of general industry compensation data. As described in more detail below, this analysis gives the Committee comparative references and enhances the Committee’s understanding of each executive’s total direct compensation package. In November 2014, the Committee decided to continue to use the Consolidated OI and ROIC performance measures for fiscal year 2015 annual cash incentive awards to maintain the emphasis on maximizing income and on strong balance sheet management. The Committee also retained the ROIC performance measure because it is a relative performance measure, requiring company performance to exceed certain thresholds compared to a peer group of companies, which we refer to as the ROIC peer group. For fiscal year 2015, the Committee did not make changes to the companies in the ROIC peer group. The companies in the ROIC peer group are shown below under “Compensation Decisions for Fiscal year 2015 — Annual cash incentive awards”. DETERMINING PAY LEVELS On an annual basis, Towers Watson provides the Committee various analyses of general industry compensation data from its Executive Compensation Database, a survey of over 900 companies. We use this database because we believe the size ensures consistent and statistically valid data that is representative of the market in which we compete for executive talent. We generally consider only aggregate data and do not select individual companies for comparison. We believe this approach avoids giving undue importance to statistically outlying companies while offering a general understanding of compensation practices in the market. The Towers Watson Executive Compensation Database includes data regarding base salary, target and actual annual cash incentive awards, and long-term incentive awards. The data reflects the individual responsibilities of each position and company revenue size. In addition to the Towers Watson market data, the Committee also considers, in a subjective manner, the annual evaluation of each executive officer’s performance when determining base salary, annual incentive awards and long-term incentive awards.

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 COMPENSATION DECISIONS FOR FISCAL YEAR 2015 Base salary The Committee reviewed the Towers Watson Executive Compensation Database data by position to evaluate the competitiveness of the NEOs’ base salaries. The Committee generally believes base salaries that are within 15% of the 50th percentile for this database are competitive. The Committee reviewed Mr. Szews’ and Mr. Jones’ performance and reviewed the performance evaluations of the other NEOs prepared by Mr. Szews to ensure that base salary decisions for each executive reflected performance and were otherwise consistent with all of the compensation goals. After analyzing the data and performance information of each executive, the Committee made the following modest base salary adjustments for fiscal year 2015, effective January 1, 2015. Adjustment as a % of Base Salary Named Executive Officer Mr. Szews 3.2% Mr. Sagehorn 3.0% Mr. Jones 3.0% Mr. Urias 3.0% Mr. Johnson 3.0% Annual cash incentive awards Our annual cash incentive plan links a cash award to the achievement of specific short-term corporate performance goals that the Committee approves each year. These awards tie a significant portion of an executive’s annual compensation to our Company’s performance. For fiscal year 2015, awards were dependent on our performance under a combination of two or, for the business segment presidents, three measures: Consolidated Operating Income, Return on Invested Capital, and Segment Operating Income. • Consolidated Operating Income (OI) equals income from continuing operations before other income/expense, income taxes, and equity in income of our unconsolidated affiliates Return on Invested Capital (ROIC) equals our net income before extraordinary items, nonrecurring gains and losses, discontinued operations and accounting changes, plus the after-tax cost of interest expense for the four quarters ended June 30, 2015, divided by the simple average of total debt plus shareholders’ equity for the five quarters ended June 30, 2015 Defense segment Operating Income equals income from continuing operations before other income/expense, income taxes, and equity in income of our unconsolidated affiliates for our Defense operating segment Fire & Emergency segment Operating Income equals income from continuing operations before other income/expense, income taxes, and equity in income of our unconsolidated affiliates for our Fire & Emergency operating segment • • • After the Committee reviewed the Towers Watson Executive Compensation Database and each executive’s performance, the Committee assigned each executive a threshold, target and maximum annual cash incentive award payment level, as a percentage of base salary for fiscal year 2015. As in the past, the annual cash incentive award opportunity was targeted at approximately the 50th percentile of the competitive data and there were no changes to the potential award as a percentage of base salary for fiscal year 2015 NEOs from fiscal year 2014. The payout opportunities for fiscal year 2015 for each of the NEOs are set forth in the table below. Potential Award as a Percentage of Base Salary Threshold Target Maximum Mr. Szews 62.5% 125% 250% Mr. Sagehorn 37.5% 75% 150% Mr. Jones 37.5% 75% 150% Mr. Urias 30% 60% 120% Mr. Johnson 30% 60% 120% OSHKOSH CORPORATION 2015 Proxy Statement 34

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 For fiscal year 2015, we gave the Consolidated Operating Income and Return on Invested Capital performance measures for Messrs. Szews, Sagehorn and Jones weightings of 80 percent and 20 percent, respectively. The Consolidated Operating Income Target level coincided with our MOVE strategy performance targets from September 2012. For Mr. Urias and Mr. Johnson, who are segment presidents, the Committee structured the annual cash incentive plan for fiscal year 2015 to reflect a weighting of 20% for Consolidated Operating Income, 60% for their respective segment Operating Income, and 20% for Consolidated Return on Invested Capital. The Committee believes it is important to provide business segment presidents the opportunity to be rewarded for results primarily tied to their business segment. Annual cash incentive awards — Operating Income The Committee established the targets for Consolidated Operating Income and Segment Operating Income based upon our forecasted financial performance, as follows: Threshold in Millions Target in Millions Maximum in Millions Performance Measure Bonus Weighting Mr. Szews Consolidated OI 80% $440 $520 $565 Mr. Sagehorn Consolidated OI 80% $440 $520 $565 Mr. Jones Consolidated OI 80% $440 $520 $565 Mr. Urias Consolidated OI Defense Segment OI 20% 60% $440 $(4) $520 $3 $565 $13 Mr. Johnson Consolidated OI Fire & Emergency Segment OI 20% 60% $440 $27 $520 $34 $565 $41 A minimum of 3% operating income margin was required to achieve any incentive compensation above “target” level. While the Defense segment threshold OI was negative, under the terms of the plan, no incentive would be paid for the OI component if OI was less than $0. Operating income results that impacted 2015 Actual annual incentive Consolidated Operating Income calculated under the terms of the plan was $395.2 million in fiscal year 2015, which was below the threshold primarily due to the unexpected acceleration of the mid-cycle dip in access equipment demand in fiscal year 2015 which we describe in the “Business Highlights” section above. Actual annual incentive Consolidated Operating Income for purposes of the plan differs from consolidated operating income as it appears in our financial statements because the applicable definition in the plan excludes certain non-cash and non-recurring items that include other post-employment benefit curtailment gains (net gain of $3.4 million) in the Defense segment. Actual annual incentive plan Defense segment Operating Income and Fire & Emergency segment Operating Income in fiscal year 2015 were $5.8 million, which was above target, and $43.8 million, which was above maximum, respectively. The annual cash incentive plan required that we achieve a minimum 3% operating income margin for an Operating Income payment above target, and the Defense segment results did not satisfy this requirement. As a result, Mr. Urias received a payment at target, although results for the Defense segment were above target. Annual cash incentive awards — Return on Invested Capital The Return on Invested Capital performance measure compares our results to the ROIC peer group. Our threshold, target, and maximum performance levels coincide with Return on Invested Capital results at the 25th, 50th and 75th percentiles, respectively, of the ROIC peer group. We believe the ROIC peer group is representative of the industrial machinery, construction machinery, heavy truck, and defense industries in which our products compete. Accordingly, we believe this focused universe of companies makes the comparison for the Return on Invested Capital measure reliable, particularly because these companies are likely to have investment needs similar to ours — both to support the maintenance and improvement of their infrastructure and to ensure continued growth.

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 The ROIC peer group for fiscal year 2015 included companies in three distinct Standard Industrial Classification (SIC) industry groupings: 25% Defense & Aerospace, 50% Construction/Farm Machinery and Heavy Trucks, and 25% Industrial Machinery, with annual revenues between approximately one quarter to two times our annual revenue. The Committee elected to retain this comparator group, without change, for fiscal year 2015. The companies in the ROIC peer group for fiscal year 2015 are listed below. Return on Invested Capital Comparator Group of Companies for Fiscal Year 2015 Industrial Machinery Construction/Farm Machinery and Heavy Trucks Defense & Aerospace Dover Corp. Flowserve Corp.

ROIC — Results that impacted 2015 Actual performance in fiscal year 2015 for our ROIC was 10.49 percent, which was at the 61st percentile of the ROIC peer group. The chart below shows our ROIC performance for fiscal year 2015 and historically relative to the 50th percentile of the ROIC peer group. This percentile ranking in fiscal year 2015 resulted in a payout for this measure equal to 144.1% of target. 40% 30% 20% 10% 0% 2010 2011 2012 2013 2014 2015 Oshkosh 50th Percentile OSHKOSH CORPORATION 2015 Proxy Statement 36 ROIC RESULTS

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 Annual cash incentive award — Results that impacted 2015 Based on these consolidated results, performance payouts under the annual cash incentive plan to our named executive officers were as follows: Award for Defense and Fire & Emergency Segments OI Award for Consolidated OI Award for ROIC Total Payout Level Mr. Szews $0 $398,450 n/a $398,450 28.8% Mr. Sagehorn $0 $135,879 n/a $135,879 28.8% Mr. Jones $0 $141,402 n/a $141,402 28.8% Mr. Urias $0 $79,713 $165,877 $245,590 88.8% Mr. Johnson $0 $59,115 $246,028 $305,143 148.8% The payout level is the sum of the results of each performance measure as a percentage of target performance multiplied by each measure’s respective weighting. We believe the payouts substantiate that our annual incentive compensation programs pay only for performance that is consistent with the results that our shareholders experience. Equity-based long-term incentive awards The Committee, in the past, generally granted individual equity awards for executives on an annual basis at its September meeting. In 2015, the Committee moved the annual equity award grant date from September to November (fiscal year 2016) which crosses over fiscal years. We did this to align the equity grant to the same time at which we approve all other compensation elements (base salary and annual incentives) for our executive officers. This allows for consideration and approval of total compensation at one meeting. Due to this change, we did not grant equity awards to the named executive officers in fiscal year 2015. We provide three types of equity-based long-term incentive awards: stock options, performance shares, and restricted stock units. Each of these awards is subject to the terms of our 2009 Incentive Stock and Awards Plan. The Committee believes equity-based, long-term incentive awards are key components of our compensation program and appropriately align pay with performance. Long-term incentive awards serve three critical functions: • • they motivate executives to focus on our long-term growth and performance; they encourage and facilitate executive ownership of our Common Stock, which aligns executive objectives with those of shareholders; and they have proven to be a valuable tool in hiring and retaining key executives, which we believe contributes to increased shareholder value. • The Committee granted equity awards to named executive officers in fiscal year 2014 that the Committee generally targeted at approximately the 50th percentile of Iong-term incentive award values in the Towers Watson Executive Compensation Database. The awards provided a significant incentive for executives to achieve our MOVE strategy goals and considerable retention value for key executives, particularly in light of the downturn we were experiencing in our defense business. In determining actual grants, the Committee decided to deliver the targeted value by awarding to each executive 30% in the form of stock options, 30% in the form of performance shares and 40% in the form of restricted stock units, which is the same mix of awards as in fiscal year 2013. The Committee valued stock options using estimated valuations under the Black-Scholes valuation model, performance shares using valuations under a Monte Carlo simulation model by a third-party provider and restricted stock units using fair market value of the Common Stock on the date of award grant. 30% Stock options The Committee believes stock options are a valuable tool. Executives realize value from stock options only when the price of our Common Stock on the date of exercise exceeds the price on the date the options are granted, creating a strong link between executive decision-making and long-term shareholder value. The Committee also believes stock option grants OSHKOSH CORPORATION 2015 Proxy Statement 37

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 enable our Company to attract highly skilled executives, which is essential to our long term success. Finally, stock options give executives the opportunity to create wealth through ownership of our Common Stock. Each stock option permits executives, for a period of seven years, to purchase shares of our Common Stock at an exercise price that is equal to the closing price of our Common Stock on the date of the grant. These stock options vest in three equal annual installments beginning one year after the grant date. 30% Performance share awards Executives benefit from the performance shares we granted in fiscal year 2014 only if our total shareholder return (TSR), which is defined as stock price appreciation plus dividends over three years subsequent to the date of the performance shares grant, compares favorably to a defined comparator group of companies. The final number of Common Shares an executive receives at the end of the three-year performance period can range from zero to double the target number of performance shares awarded, depending on our relative TSR. Performance shares support the Committee’s objective of increasing executives’ ownership interest in our Company, but only if and to the extent that shareholder value is enhanced as well. Executives will earn shares under the award terms if we achieve a TSR that is at least equal to the 25th percentile of the TSR achieved by the companies comprising the Standard & Poor’s MidCap 400 Index over the same three-year performance period. The Committee chose the Standard & Poor’s MidCap 400 Index rather than the more targeted ROIC comparator group because the index reflects the Committee’s view that there is a broad range of investment options available to shareholders. The schedule below reflects the percent of target performance shares that an executive could earn at the end of the three-year period based on our performance, which is the same schedule that applied to awards beginning in fiscal year 2013: 3-Year Total Shareholder Return Percentile Percent of Target Shares Award Earned Below 25th Percentile 0% 25th Percentile 50% 50th Percentile 100% 75th Percentile 200% These awards reinforce our pay for performance philosophy by providing target (100%) payout only if we achieve at least the 50th percentile. Executives can earn up to a 200% maximum payout for TSR performance at or above the 75th percentile, but that potential award is subject to a payout cap equal to 400% of the aggregate value of the number of shares the executive would have received for TSR performance at the 50th percentile. This cap is calculated using our share price on the date performance shares are awarded. In addition to being performance-based, the vesting of our performance shares only after three years of continuous employment (subject to retirement terms of the awards) provides a retention incentive during the full vesting period. TSR — Results that impacted 2015 For performance share awards that we granted in fiscal year 2012 relating to performance over fiscal year 2013, 2014 and 2015, our total shareholder return of 34.9 percent resulted in a rank at the 46th percentile versus the comparator group which was the Standard & Poor’s MidCap 400 Index. This percentile ranking resulted in a payout at 65 percent of target under these awards, which resulted in payouts to the named executive officers at the values shown below. Mr. Szews N/A Mr. Sagehorn $664,680 Mr. Jones $691,265 Mr. Urias $292,442 Mr. Johnson $212,685 The dollar values in the table represent the closing price of our stock on October 15, 2015, the date of payout for the performance share awards, times the number of shares of Common Stock that the NEO earned, plus accumulated dividends. OSHKOSH CORPORATION 2015 Proxy Statement 38

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 Mr. Szews asked not to be granted a fiscal 2012 performance share award primarily to ensure Oshkosh managers received appropriate equity compensation awards to enhance retention of a talented team during a time of difficult market conditions. Performance share awards granted prior to fiscal year 2013 had a different payout scale than detailed above. The payout scale for performance share awards that we granted in fiscal year 2012 was as follows: 3-Year Total Shareholder Return Percentile Percent of Target Shares Award Earned Below 40th Percentile 0% 40th Percentile 50% 60th Percentile 100% 80th Percentile 200% 40% Restricted stock units The Committee believes restricted stock units (RSUs) are valuable because they tie a portion of the executive’s compensation to stock price appreciation and the vesting period provides a retention incentive. RSUs enable executives to realize value based on the price of our Common Stock on the vesting date, creating a link between executive decision-making and shareholder value. Each RSU grant has a three-year vesting period, with one-third vesting each year. RSUs call for accelerated vesting upon a qualified retirement unless the qualified retirement occurs prior to the first anniversary of the grant date, in which case only a pro-rata portion of the RSUs will vest. For Mr. Szews, who is currently eligible for early retirement, full vesting will occur upon his retirement. Retirement Benefits We have long offered a variety of plans that provide retirement benefits based on competitive market trends. The retirement plans for the NEOs include a 401(k) plan with company matching contributions, as well as an additional company contribution based on age and base salary. We provide substantially similar 401(k) benefits to the salaried employees in our corporate office and certain business segments. We also offer non-qualified supplemental executive retirement plans that are available to executives on the recommendation of the Chief Executive Officer and with Committee approval. See “Pension Benefits” for more information regarding our supplemental executive retirement plans and our pension plan. We maintain a qualified defined contribution retirement benefit plan under which we contribute a percentage of base salary for each participant up to Internal Revenue Code limits for such plans based on age. The contributions vary by business segment and employee groups. For the named executive officers, the contributions as a percentage of qualifying wages are as follows: under age 30, 3%; age 30 to 39, 4%; age 40 to 49, 5%; and age 50 and older, 6%. For NEOs and other executives who were eligible to participate in our frozen non-qualified defined benefit supplemental executive retirement plan, we maintain a non-qualified defined contribution supplemental executive retirement plan that provides a percentage of base salary and bonus based on age. The contributions are as follows: under age 45, 10%; age 45 to 50, 12.5%; and over age 50, 15%. This plan was discontinued on December 31, 2012, and no new participants have been added since that date. For newer executive officers, we maintain a restoration, non-qualified defined contribution plan that provides a percentage of base salary and bonus above the Internal Revenue Code retirement plan limits that apply to our broad-based defined contribution retirement plan. The contributions above the Internal Revenue Code limits are as follows: under age 30, 3%; age 30 to 39, 4%; age 40 to 49, 5%; and age 50 and older, 6%. Deferred Compensation Our NEOs are eligible to participate in our Deferred Compensation Plan for Directors and Executive Officers, which is a non-qualified, unfunded retirement savings plan. The Deferred Compensation Plan allows the deferral of base salary and annual cash incentive awards into either an investment program, which pays a guaranteed rate of return based on the prime interest rate plus 1%, or a share program, which mirrors the performance of our Common Stock during the relevant time period, including dividends. Executives also may defer restricted stock grants and performance shares under the Deferred Compensation Plan. See “2015 Non-qualified Deferred Compensation” for more information regarding our deferred compensation plans. OSHKOSH CORPORATION 2015 Proxy Statement 39

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 Certain Benefits During fiscal year 2015, we provided limited additional personal benefits to certain executive officers. Executive use of our company plane for personal reasons is authorized only in limited and specific circumstances. There were two such uses in fiscal year 2015. We provided health and welfare benefit plans to all of our executives under the plans available to most of our employees, including medical, dental, vision, life insurance, and short-and long-term disability coverage. In addition, all of our executives were eligible to receive a comprehensive physical examination. We covered costs of these examinations in fiscal year 2015 and also reimbursed the taxes relating to those services. The named executive officers also may utilize the normal health plan for routine annual physicals as needed. Mr. Szews’ employment agreement requires him to have an annual physical examination. Executive Employment and Other Agreements The only NEO with whom we have an employment agreement is Mr. Szews. The other named executive officers have agreements under which certain benefits would become payable in the event of a change in control of our Company and subsequent termination of the executive’s employment. Mr. Szews also has a change-in-control severance agreement; his employment agreement does not provide for benefits in the event of a change in control of our Company. Employment Agreement with Charles Szews We have an employment agreement with Mr. Szews because he holds a critical position that is highly visible to the investment community and other outside constituents. The employment agreement contains restrictive and protective covenants, such as an agreement not to compete with us for a certain time should Mr. Szews decide to terminate his employment, which protects our Company. The term of the agreement automatically renews and extends annually for periods of one year unless either party gives notice of nonrenewal. The employment agreement will terminate when Mr. Szews retires from our Company on December 31, 2015. The employment agreement provides that Mr. Szews is entitled to a base salary of a specified amount and the right to participate in all employee benefit plans offered to our other senior executives. If we terminate Mr. Szews’ employment without cause or Mr. Szews terminates his employment for good reason, then, provided he executes a release of claims against us, Mr. Szews generally will be entitled to receive, in lieu of base salary and bonus for the remaining term of the employment agreement, severance pay in an amount determined pursuant to the terms of the employment agreement. If Mr. Szews is entitled to severance pay, then he is obligated to make himself available to consult with and otherwise assist or provide general advice to our then Chief Executive Officer and to our Board of Directors as they reasonably request during the two-year period after the date of termination. See “Potential Payments upon Termination or Change in Control” for more information regarding Mr. Szews’ employment agreement and potential amounts that we may pay under that agreement. Change in Control Agreements We have severance agreements with all five named executive officers that would provide each of them with reasonable compensation if their employment is terminated in certain defined circumstances following a change in control of our Company. We entered into these agreements to provide our Company with certain protections — specifically to retain key executives prior to or following a change in control and to ensure key executives consider the best interests of shareholders when making decisions during a potential or actual change in control. The Committee administers the severance agreements and selects executive officers who are eligible for these agreements. In fiscal year 2009, the Committee eliminated the Internal Revenue Code Section 280G tax gross up benefit from payments due under new severance agreements. Although the Committee has since approved amendments to certain severance agreements that our Company had entered into prior to the Committee’s determination, the amendments that the Committee has approved with respect to those severance agreements that provide for a Section 280G tax gross up benefit have been only those necessary to cause such severance agreements to comply with Internal Revenue Code Section 409A.

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 Under the executive severance agreements, after a change in control of our Company, if an executive’s employment is terminated other than by reason of death, disability or for cause, then the executive is entitled to the following: Outplacement, Legal, Continued Welfare Benefits Additional Retirement Benefits Tax Gross-up for “Excess Parachute Payments”(1) Cash Payment Mr. Szews 3x base salary and bonus Present value pension benefit 3 years Yes Mr. Sagehorn 3x base salary and bonus Present value pension benefit 3 years Yes Mr. Jones 2x base salary and bonus n/a 2 years No Mr. Urias 2x base salary and bonus n/a 2 years No Mr. Johnson 2x base salary and bonus n/a 2 years No (1) In fiscal 2009, the Committee eliminated the Internal Revenue Code Section 280G tax gross up benefit from payments due under severance agreements for any new agreements after that date. Each executive is also entitled to a cash termination payment and other benefits if the executive terminates employment for good reason, as defined in the severance agreements, after a change in control. The form of agreement to which Messrs. Jones, Urias and Johnson are a party provides that, to the extent that payments to any of those executives would be considered “excess parachute payments,” the payments will be reduced to a point at which they are no longer considered excess parachute payments, or the executive will receive the full payment and be personally liable for the excise tax, whichever produces the larger after-tax benefit to the executive. The Committee has approved severance agreements for other officers with terms that are not as favorable to those officers (among other things, by providing for a maximum of one times base salary and bonus), and the Committee carefully selects the appropriate agreement for a given executive after considering market conditions and other relevant circumstances in each case. See “Potential Payments upon Termination or Change in Control” for more information regarding these severance agreements and potential amounts under them to our NEOs. In light of Mr. Jones’ promotion to President and Chief Executive Officer effective January 1, 2016 following the retirement of Mr. Szews, the Committee, at its November 2015 meeting, approved the following compensation for Mr. Jones: • • His annual base salary will increase 52% effective January 1, 2016. His target annual incentive payment for fiscal year 2016 will increase to 115%, with corresponding increases in his threshold and maximum amounts. He received equity awards with a target value of $4,500,000, consisting of stock options, performance share awards and restricted stock units. • The Committee believes this compensation is consistent with the compensation philosophy that we describe above and moves Mr. Jones’ compensation toward median compensation in his first year as Chief Executive Officer based on the competitive compensation data. In addition, we intend to enter into a severance agreement with Mr. Jones that will entitle him, under certain circumstances, to severance compensation approximating two years’ salary and bonus, together with welfare benefits, provided he executes a release of claims against us. Finally, we intend to enter into a revised change in control agreement with Mr. Jones to increase his severence benefit from two times annual salary and bonus to three times annual salary and bonus and to increase his welfare benefits from two years to three years in the event his employment is terminated after a change in control. Executive Incentive Compensation Recoupment Policy In September 2011, the Committee adopted the Oshkosh Corporation Executive Incentive Compensation Recoupment Policy, which is also known as a “clawback policy”. The policy applies to all non-equity incentive compensation and equity awards granted on or after September 30, 2011. Under the policy, if we must prepare an accounting restatement relating to our publicly-reported consolidated financial statements due to our material noncompliance with financial reporting requirements under U.S. federal securities laws, then our Company will have the right, to the extent permitted by law, to take appropriate action to recoup all or part of any incentive award actually paid to a covered executive if the amount of money or number of shares paid to the executive was expressly based on the achievement of financial results that were subject to the restatement and the executive would have been paid a lower amount or number of shares based on the financial results after the restatement. OSHKOSH CORPORATION 2015 Proxy Statement 41

COMPENSATION DISCUSSION AND ANALYSIS | Compensation Decisions for Fiscal Year 2015 Stock Ownership Guidelines for Executive Officers The Committee has adopted executive officer stock ownership guidelines to align our executives’ interests with those of shareholders. The Committee requires executives to attain stock ownership at the following levels: Chief Executive Officer Five Times Annual Base Salary Chief Operating Officer Four Times Annual Base Salary Chief Financial Officer Four Times Annual Base Salary Executive Vice Presidents Three Times Annual Base Salary It is the Committee’s policy that each NEO must achieve the required level of stock ownership within five years of becoming a NEO. Stock ownership includes stock that is not restricted in any way and the value of exercisable “in-the-money” stock options, based upon the market price of our Common Stock, the exercise price, and taxes the officer would pay on exercise. An executive who does not meet the ownership guidelines within the requisite timeframe will not receive approval to sell shares or to exercise options unless the net proceeds of that transaction are reinvested in Common Stock. As of November 19, 2015, all NEOs have exceeded their respective stock ownership requirements. We prohibit senior management from entering into certain transactions for their individual accounts that include hedging or pledging our Company securities and trading in puts, calls or other derivative securities relating to our Company’s securities. Tax Treatment of Compensation Section 162(m) of the Internal Revenue Code limits our income tax deduction for compensation that exceeds $1,000,000 paid in any taxable year to certain executive officers, unless such compensation falls within certain exceptions. The Committee uses its best efforts to cause any compensation paid to executive officers in excess of this dollar limit to qualify for such exceptions. The Committee views the tax deductibility of executive compensation as one of the many factors to be considered in the context of its overall compensation objectives. Relation of Our Compensation Policies and Procedures to Risk Management Our senior management conducted a comprehensive risk assessment of each of our material compensation programs to evaluate the levels of risk-taking that each of those programs could potentially encourage. Management then presented this risk assessment to the Committee. After reviewing management’s risk assessment, the Committee determined that our compensation programs effectively create a proper balance between appropriate risk-taking and competitive compensation. Based on the Committee’s determination, we believe our compensation programs do not create risks that are reasonably likely to have a material adverse effect on our Company. Conclusion Our compensation program for fiscal year 2015 achieved its objective of tying pay to performance. Company performance did not meet our high expectations, and accordingly, incentive pay was sharply reduced. To prudently manage our compensation expense, we generally targeted compensation close to the 50th percentile of the compensation databases that we use. We believe our executive compensation programs position us to compete effectively when recruiting, selecting, and seeking to retain key executives. The Committee believes that executive retention is even more critical to keep this high-performing team in place, particularly as alternative employment opportunities become more frequently available and our executives continue to be a prime target of certain executive search firms. Human Resources Committee Report The Human Resources Committee has reviewed and discussed the Compensation Discussion and Analysis required by item 402(b) of Regulation S-K with management. Based on such review and discussions, the Human Resources Committee recommended to our Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement. » Peter B.

COMPENSATION TABLES | Compensation Tables The following tables relate to the compensation of the Chief Executive Officer, the Chief Financial Officer and the three other most highly compensated executive officers during fiscal year 2015, who are referred to as the Named Executive Officers. 2015 Summary Compensation Table (1) We are not including information for Mr. Johnson for prior fiscal years because Mr. Johnson was not a named executive officer prior to fiscal year 2015. (2) Amounts in this column are based on the aggregate grant date fair value of awards to our named executive officers under our 2009 Incentive Stock and Awards Plan rather than actual amounts paid to these officers or amounts the officers actually realized or will realize as a result of these awards. We computed the aggregate grant date fair value of these awards in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718, Stock Compensation (“FASB ASC Topic 718”), except that, for awards that are subject to performance conditions, we reported the value at the grant date based upon the probable outcome of such conditions. We based the fair value of all stock awards on the market price of the underlying shares awarded on the date of grant (which considers the value of dividends that the holder of restricted stock units is entitled to receive). We calculated the fair value of option awards using a Black-Scholes valuation model. Note 17 to our audited consolidated financial statements for the fiscal year ended September 30, 2015, included in our Annual Report on Form 10-K filed with the SEC on November 13, 2015, includes the assumptions we used to calculate these amounts. We have granted performance shares that vest at the end of the third fiscal year following the grant date to certain of our named executive officers. Our named executive officers earn shares under performance share awards that we granted prior to fiscal year 2015 only if our total shareholder return over the three-year performance period compares favorably to that of a comparator group of companies. Potential payouts range from 0% to 200% of the target amounts for these awards. Amounts in this column relating to these performance share awards are the value at the grant date, consistent with the estimate of the aggregate compensation cost to be recognized over the service period in accordance with FASB ASC Topic 718, determined using a Monte Carlo simulation model.

COMPENSATION TABLES | In 2015, the Committee moved the annual equity award grant date from September to November (fiscal year 2016), which crosses over fiscal years. We did this to align the equity grant to the same time at which we approve all other compensation elements (base salary and annual incentives). As a result, we did not grant equity awards in fiscal year 2015. (3) The amounts in this column reflect the change in actuarial present value from the prior year of the named executive officer’s benefits under our applicable retirement plans determined using the assumptions set forth in footnote (1) to the Pension Benefits Table below. As we discuss more fully elsewhere, we froze benefits under both our qualified and non-qualified defined benefit plans effective December 31, 2012, and now provide benefits under new, qualified and non-qualified defined contribution plans. (4) The amounts shown in this column include benefits earned in fiscal year 2015 under the Defined Contribution Executive Retirement Plan of $225,681 for Mr. Szews, $139,248 for Mr. Sagehorn, $119,324 for Mr. Jones, $106,002 for Mr. Urias and $66,408 for Mr. Johnson.

(2) In 2015, the Committee moved the annual equity award process from September 2015 to November 2015 (fiscal year 2016), which crosses over fiscal years. This change was done to align the equity grant to the same time at which all other compensation elements (base salary and annual incentives) for our named executive officers were being approved. As a result, no equity awards were granted to the NEOs in fiscal year 2015. OSHKOSH CORPORATION 2015 Proxy Statement 44

Participants do not accrue additional years of credited service under the Retirement Plan or the Executive Retirement Plan after December 31, 2012, but vesting service continues under both plans. (2) The actuarial values of the accumulated plan benefits for the Retirement Plan and the Executive Retirement Plan were calculated using the unit credit valuation method and the following assumptions, among others: that the participants retire at their first unreduced retirement age of 62; that the benefit calculation date is September 30, 2015, consistent with our accounting measurement date for financial statement reporting purposes; a discount rate of 4.30%; a post-retirement mortality assumption based on the RP-2014 table with MP-2015 mortality improvement scale using a generational projection; final average pay based on OSHKOSH CORPORATION 2015 Proxy Statement 47

COMPENSATION TABLES | current average pay, without projection; payment in the form of a single life annuity; that the Retirement Plan benefit accrued ratably over the participant’s years of service up to December 31, 2012, the date benefits were frozen; and that the Executive Retirement Plan benefit accrued ratably over the first 20 years from the date of hire up to December 31, 2012, the date benefits were frozen, and vested (or will vest) 20% per year from years 5 to 10 beginning when the employee became an officer. Oshkosh Corporation Retirement Plan — Under the Retirement Plan, a salaried employee is entitled to receive upon retirement at age 65 a monthly benefit equal to 50% of average monthly compensation less 45% of the primary social security benefit payable at age 65, reduced by 1/30th for each benefit accrual year of service less than 30, or certain actuarially equivalent benefits. Average monthly compensation is based on the average of the five highest consecutive years of base salary (subject to a maximum established pursuant to IRS regulations) prior to the participant’s normal retirement age or other date of termination. One thousand hours constitute a year of service. As of March 1, 1994, IRS regulations lowered the maximum amount of compensation allowed to be included in benefit calculations from $235,840 to $150,000. This amount was increased to $160,000 as of March 1, 1997, $170,000 as of January 1, 2000, $200,000 as of January 1, 2002, $205,000 as of January 1, 2004, $210,000 as of January 1, 2005, $220,000 as of January 1, 2006, $225,000 as of January 1, 2007, $230,000 as of January 1, 2008, $245,000 as of January 1, 2009 and $250,000 as of January 1, 2012. Accrued benefits calculated as of February 28, 1994 at the higher limit have been grandfathered. An employee who has reached the age of 55 with a minimum of five years of service may retire and begin to receive the actuarial equivalent of his or her pension benefits. The pension benefits payable to such an employee are equal to 50% of the pension benefits that would have been payable had the employee remained employed with us until age 65. The percentage paid increases for each year of continued service with us between the date on which the employee reaches age 55 and the date on which the employee reaches age 65. The spouse of an employee who dies after becoming eligible for early retirement is entitled to a monthly benefit equivalent to 50% of the amount of the life annuity that would have been payable to a participant at normal retirement age. As of September 30, 2015, Mr. Szews was the only named executive officer eligible for retirement under the Retirement Plan. Benefits under the Retirement Plan were frozen effective December 31, 2012; we now provide benefits under a new, qualified defined contribution plan. Oshkosh Corporation Executive Retirement Plan — Under the Executive Retirement Plan, certain of our officers, including the named executive officers, are entitled to receive upon retirement a monthly benefit equal to 24% of their average monthly compensation at age 55, increasing to 40% of average monthly compensation at age 62, in each case prorated if the executive has less than 20 years of service at retirement. This amount is reduced by the amount of any pension payable by us under the Retirement Plan, the annuity value of the executive’s 401(k) plan match, and 50% of the executive’s social security benefit. Average monthly compensation is based on the average of the executive’s compensation (base salary plus bonus) for the highest five years of pay (not necessarily consecutive) in the last ten years of credited service. The spouse of an executive who dies after becoming eligible for early retirement is entitled to receive 50% of the Executive Retirement Plan benefit that would have been payable to the executive. As of September 30, 2015, Mr. Szews was the only named executive officer eligible for early retirement under the Executive Retirement Plan. Benefits under the Executive Retirement Plan were frozen effective December 31, 2012; we now provide benefits under a new, non-qualified defined contribution plan. 2015 Non-Qualified Deferred Compensation Aggregate Balance at Last Fiscal Year End ($) (3) Aggregate Earnings in Last Fiscal Year ($) (2) Registrant Contributions in Last Fiscal Year ($) (1) Executive Contributions in Last Fiscal Year ($) Aggregate Withdrawals/ Distributions ($) Name Charles L.

The remaining amounts shown in this column represent benefits earned under the Defined Contribution Executive Retirement Plan, which amounts also appear in the “All Other Compensation” column in the 2015 Summary Compensation Table. (2) The amounts shown in this column represent earnings in fiscal year 2015 that are neither above market nor preferential. Accordingly, the amounts are not included in the Summary Compensation Table for fiscal year 2015. With respect to Mr. Szews’ restricted stock units, the earnings reflect the change in the market value of the shares of Common Stock that he is entitled to receive in respect of such restricted stock units, together with dividends on those shares. (3) The amount shown in this column in excess of the sum of the amounts from the preceding columns includes $794,651 for Mr. Szews, $301,806 for Mr. Sagehorn, $369,673 for Mr. Jones and $122,611 for Mr. Urias that was previously reported in the Summary Compensation Table for years prior to fiscal year 2015. Mr. Johnson was not a named executive officer in the relevant prior years. Oshkosh Corporation Deferred Compensation Plan for Directors and Executive Officers — Under the Deferred Compensation Plan, each participating named executive officer may defer up to 65% of base salary for the plan year, up to 85% of annual incentive compensation payable in the plan year for services and performance during the preceding plan year, and up to 100% of any share-based long-term incentives. An executive participating in the Deferred Compensation Plan may elect to have deferrals credited to a fixed-income investment account or a stock account. Deferrals credited to a fixed-income investment account earn interest at the prime rate as published in The Wall Street Journal on the last business day of the immediately preceding plan year quarter, plus 1%. Deferrals credited to a stock account are treated as though invested in our Common Stock. Any dividends earned on our Common Stock are reinvested in each executive’s stock account. Payments from the Deferred Compensation Plan may be made in a lump sum or in annual installments for up to ten years, at the election of the executive. Payments generally commence six months after the executive’s separation from service with us. However, in the event of a change in control, as defined in the Deferred Compensation Plan, we will pay out the accounts of all executives in a single lump sum cash payment. Oshkosh Corporation Defined Contribution Executive Retirement Plan — Under our non-qualified Defined Contribution Executive Retirement Plan, certain of our officers, including the named executive officers, are entitled to receive, upon separation from service, cash distributions of either a single lump sum payment or annual installments over a period of two to ten years, as elected by the participant, equal to the vested balance of the participant’s account. A participant’s account balance is equal to the sum of annual benefit credits made to the account, adjusted for returns based on the hypothetical investment experience of the selected investment option. For any participant in our Executive Retirement Plan on December 31, 2012, the annual benefit credits are equal to a percentage of the participant’s annual base pay and bonus. The percentage of compensation earned is 10% for participants age 44 or below; 12.5% for participants age 45 to 50; and 15% for participants age 51 or above. For individuals who became participants in our Executive Retirement Plan after December 31, 2012, the annual benefit credit is equal to the excess of the employer non-elective contribution under our tax-qualified Oshkosh Corporation and Affiliates Tax Deferred Investment Plan that would have been made for the applicable year but for the effect of the limitations imposed by Section 401(a)(17) or Section 415 of the Internal Revenue Code, over the amount of the contribution actually made. Effective June 1, 2014, all participants are immediately 100% vested. Each participant’s accumulated benefits change based on the hypothetical investment experience of the selected investment option. Available hypothetical investment options generally are the same as the investment options available under our tax-qualified defined contribution retirement plan. Potential Payments Upon Termination Or Change In Control The following tables disclose potential payments and benefits to which our NEOs would be entitled upon a termination of employment or a change in control of our Company. We list the estimated amount of compensation payable to each of our NEOs in each situation in the tables below assuming that the termination or change in control occurred at September 30, 2015, and that our Common Stock had a value per share of $36.33, which was the closing market price on September 30, 2015. The actual amount of payments and benefits can only be determined at the time of such a termination or change in control, and likely would vary from the estimated amounts in the tables below.

COMPENSATION AGREEMENTS | Change In Control Agreements We currently have in effect Key Executive Employment and Severance Agreements, or KEESAs, with our executive officers, including each of our named executive officers. Under the KEESAs, after a change in control of our Company, if the executive’s employment is terminated, other than by reason of death, disability or for cause, then the executive is entitled to a cash termination payment and other benefits. The executive also is entitled to a cash termination payment and other benefits if, after the change in control, the executive terminates his or her employment for good reason. The termination payment will be equal to the sum of the executive’s annual salary in effect at the change in control (or any subsequent higher salary) plus the highest annual bonus award paid during the three years before the change in control, multiplied by the number of years remaining in the employment period (up to three but at least one for Messrs. Szews and Sagehorn, and up to two, but at least one, for Messrs. Jones, Urias, and Johnson). The amounts in the tables assume the maximum three years for Messrs. Szews and Sagehorn, or two years for Messrs. Jones, Urias and Johnson, remaining in the employment period. If Mr. Szews or Mr. Sagehorn is entitled to a cash termination payment, then such executive also is entitled to the difference between the unreduced social security benefit payable if his employment continued until his unreduced social security age and the actual social security benefit payable at the end of the employment period. This payment ceases at the executive’s unreduced social security age. These benefits are disclosed as “Additional Change in Control Retirement Benefits” in the tables above. In addition, the KEESAs provide for outplacement services and continuation of life and disability insurance for up to three years, for Messrs. Szews and Sagehorn, or two years, for Messrs. Jones, Urias and Johnson, as well as hospitalization, medical and dental coverage and other welfare benefits as in effect at the termination. The KEESAs for Messrs. Szews and Sagehorn provide that if the payments under the agreement are an “excess parachute payment” for purposes of the Internal Revenue Code, then we will pay the executive the amount necessary to offset the 20% excise tax the Internal Revenue Code imposes and any additional taxes on this payment. To the extent that payments to Messrs. Jones, Urias and Johnson under their agreements would be considered “excess parachute payments”, the payments will be reduced to a point at which they are no longer considered excess parachute payments, or the executive will receive the full payment and be personally liable for the excise tax, whichever produces the larger after-tax benefit. In fiscal year 2008, we revised the terms of the KEESAs to ensure that payments under the agreement are not “income includible under Section 409A” for purposes of the Internal Revenue Code. However, if payments under the agreement are nonetheless “income includible under Section 409A”, then we can be obligated to pay the executive the 20% additional income tax that Internal Revenue Code Section 409A imposes and interest and any additional taxes on this payment. In consideration of the KEESA benefits, each executive officer party to a KEESA agrees not to compete with us for a period of 18 months after leaving his position and to keep in confidence any proprietary or confidential information for the same period of time. Our Board of Directors can waive both of these conditions. Under the KEESAs, there is a “change in control” if: • any person is or becomes the beneficial owner of securities representing 25% or more of our outstanding Common Stock; there is a change in the composition of our Board of Directors that at least two-thirds of the existing directors have not approved; a merger, consolidation or share exchange with any other corporation (or the issuance of voting securities in connection with a merger, consolidation or share exchange) is consummated, after which our shareholders control less than 50% of combined voting power; or our shareholders approve a plan of complete liquidation or dissolution or a sale or disposition by us of all or substantially all of our assets is consummated. • • • This definition of change in control also applies to both the Oshkosh Corporation 2004 Incentive Stock and Awards Plan and the Oshkosh Corporation 2009 Incentive Stock and Awards Plan. Under the KEESAs, the term “cause” generally means: • • • • • committing any act of fraud, embezzlement or theft in connection with the executive’s duties; continuing, willful and unreasonable refusal by an executive to perform duties or responsibilities; willfully engaging in illegal conduct or gross misconduct that causes us demonstrable and serious financial injury; willfully disclosing our trade secrets or confidential information; or engaging in competition with us that our Board of Directors determines to be materially harmful to us. OSHKOSH CORPORATION 2015 Proxy Statement 53

COMPENSATION AGREEMENTS | Under the KEESAs, the term “good reason” generally means: • • a breach of the agreement by us; any reduction in the executive’s base salary, percentage of base salary available as incentive compensation or bonus opportunity, or benefits; a material adverse change in the executive’s working conditions or status with us from such working conditions or status in effect during the 180-day period prior to the change in control, including a significant change in the nature or scope of his or her authority, powers, functions, duties or responsibilities or a significant reduction in the level of support services, staff, secretarial and other assistance, office space and accoutrements, but in each case excluding for this purpose an isolated, insubstantial and inadvertent event not occurring in bad faith that we remedy promptly after receipt of notice thereof; relocation of the executive’s principal place of employment to a location more than 50 miles from the executive’s principal place of employment during the 180-day period prior to the change in control; a mandate that the executive travel on business to a materially greater extent than was required during the 180-day period prior to the change in control; our failure to cause a successor to assume the executive’s agreement; or termination of the executive’s employment after a change in control without proper notice. • • • • • Stock Option Agreements We have granted stock option awards to our named executive officers under the Oshkosh Oshkosh Corporation 2009 Incentive Stock and Awards Plan. Under these plans and the related award terms, if an executive’s employment terminates due to death or disability, then the option award will become fully vested and will remain exercisable by the executive or his or her beneficiary for a period of one year after the date of such death or disability. If the executive’s employment terminates due to retirement, then the option award will become fully vested and will remain exercisable by the executive for a period of three years after the date of such retirement. Effective upon a change in control of our Company, the option award will fully vest and immediately become exercisable, and the executive holding the option award will have the right to receive, in exchange for surrender of each option, an amount of cash equal to the excess, if any, of the fair market value of a share of our Common Stock as determined on the date of exercise over the exercise price of the option. The amounts in the tables above include the value attributable to unvested stock options that our named executive officers held valued at the amount by which the closing price of our Common Stock on September 30, 2015, exceeds the exercise price of the unvested options. Performance Share Awards We have granted performance share awards to our named executive officers under the Oshkosh Corporation 2009 Incentive Stock and Awards Plan. Under these plans and the related award terms, if an executive’s employment terminates due to death, disability or retirement after the tenth trading day of the performance period in respect of an award, then the executive will receive a proportionate number of the shares of our Common Stock that the executive would have received had the performance period ended on the date of termination. If we cease to employ an executive for any reason other than death, disability or retirement, then the executive will forfeit any rights with respect to an award of performance shares. In the event of a change in control of our Company, the executive will be fully vested in the number of shares of our Common Stock calculated as if the performance period for the related award ended on the date of the change in control. The amounts relating to performance share awards that we granted in fiscal years 2013 and 2014, respectively, reflect a payment amount equal to 0% and 52% of the target performance share awards based on our total shareholder return during the performance period calculated as of September 30, 2015. Restricted Stock Units We have granted restricted stock unit awards to our named executive officers under the Oshkosh Corporation 2009 Incentive Stock and Awards Plan. Under this plan and the related award agreements, if an executive’s employment terminates due to death or disability, then any restricted stock units that are not vested will become fully vested at the time of such termination. The restricted stock units also fully vest if an executive’s employment is terminated as a result of a qualified retirement, except that, for our named executive officers other than Mr. Szews, if the qualified retirement OSHKOSH CORPORATION 2015 Proxy Statement 54

COMPENSATION AGREEMENTS | occurs prior to the first anniversary of the grant date of the restricted stock unit award, then only a pro-rata portion of the restricted stock units will vest. We define qualified retirement as a retirement at a time when the executive is at least 55 years of age and the executive’s age, when added to his or her years of service with our Company, equals or exceeds 70. No named executive officer, other than Mr. Szews, was eligible for a qualified retirement at September 30, 2015. If we cease to employ an executive for any reason other than death, disability or a qualified retirement, then any restricted stock units held by the executive that are not vested on the date of such termination will be immediately forfeited. Effective upon a change in control of our Company, any restricted stock units that have not vested will vest and the executive will have the right to receive, in exchange for surrender of such restricted stock units, shares or an amount of cash equal to the greatest of (i) the fair market value of a share of our stock as determined on the date of the change in control, (ii) the highest per share price paid in the change in control transaction, or (iii) in certain change in control transactions, the fair market value of a share calculated on the date of surrender. Annual Cash Incentive Awards Upon a change in control of our Company, for any annual cash incentive award that a named executive officer has not then earned, the executive is entitled to receive a proportionate amount of his or her annual cash incentive target award opportunity, based on the number of whole months that have elapsed in the fiscal year prior to the change in control. For each named executive officer, the amounts we disclose as “Unearned Annual Cash Incentive Awards” in the tables above assume that the change in control occurred prior to the end of the fiscal year (meaning the named executive officers did not yet earn their annual cash incentive awards), but the amounts reflect the full target award opportunity rather than only a proportionate amount. The Summary Compensation Table reflects the actual amount of the annual cash incentive award that each named executive officer earned for fiscal year 2015. Named executive officers would not be entitled to receive both the amount in the tables above and the amount in the Summary Compensation Table. For purposes of determining the amount of any excise tax that the Internal Revenue Code may impose because we paid an executive’s annual cash incentive target award opportunity upon a change in control of our Company (and to enable us to estimate any excise tax gross-up payment that we would have to pay to Mr. Szews or Mr. Sagehorn), we assume the executive has earned the entire amount of the award as of September 30, 2015. Oshkosh Corporation Executive Retirement Plan Upon a change in control of our Company, executives participating in our Executive Retirement Plan are vested without regard to the normal vesting schedule under the plan. Furthermore, if an executive’s employment is terminated for any reason following the change in control, the executive will be entitled to receive a single lump sum cash payment equal to the present value (as determined under the Executive Retirement Plan) of the executive’s earned and vested benefits under the Executive Retirement Plan through December 31, 2004, within 60 days after the termination of the executive’s employment. “Change in control” is defined in the same manner as under the KEESAs for this purpose. The executive also will be entitled to receive a single lump sum cash payment equal to the present value (as determined under the Executive Retirement Plan) of the executive’s earned and vested benefits under the Executive Retirement Plan for the period commencing January 1, 2005, within 60 days of the change in control. “Change in control” has a specified meaning for this purpose as defined in the Executive Retirement Plan. The amounts we disclose as “Executive Retirement Plan Benefits” in the tables above include, for the two named executive officers who were not fully vested in their pension benefits (Mr. Jones and Mr. Johnson), the value of the accelerated vesting of their benefits resulting from the change in control and, for each of the named executive officers, the incremental increase in the value of their benefits resulting from the use of lump-sum-specific mortality and interest rate assumptions required by the Executive Retirement Plan that may differ from those used to calculate the monthly benefit that would have been paid upon retirement absent a change in control. Defined Contribution Executive Retirement Plan Under the Oshkosh Corporation Defined Contribution Executive Retirement Plan, following a change in control of our Company, any participant who is terminated will be entitled to receive an immediate single sum distribution of his or her account balance within 60 days. OSHKOSH CORPORATION 2015 Proxy Statement 55

COMPENSATION AGREEMENTS | Deferred Compensation Plans Termination of an executive officer or a change in control of our Company would not affect the amounts payable to our named executive officers under the Oshkosh Corporation Deferred Compensation Plan for Directors and Executive Officers. Executive Employment Agreement with Mr. Szews We have an employment agreement with Mr. Szews that automatically renews and extends annually for periods of one year unless either party gives notice of nonrenewal. The employment agreement will terminate upon Mr. Szews’ retirement from our Company on December 31, 2015. Under his employment agreement, we have the right to terminate Mr. Szews’ employment at any time. If we terminate Mr. Szews’ employment without cause or Mr. Szews terminates his employment for good reason, provided Mr. Szews executes a release of claims against us, he generally will be entitled to receive as severance pay, in lieu of base salary and bonus for the remaining term of the employment agreement, an amount equal to the sum of (i) two times the sum of (A) Mr. Szews’ then current base salary, plus (B) a representative annual bonus amount for Mr. Szews, and (ii) if Mr. Szews will not receive a bonus with respect to the fiscal year in which such termination occurs under the bonus plan then in effect solely as a result of the termination of his employment, a pro rata bonus for the fiscal year in which the termination occurs in an amount based upon the bonus (if any) that Mr. Szews would have received had he remained employed through the entire fiscal year. If Mr. Szews is entitled to severance pay, then, for no additional consideration, Mr. Szews is obligated to make himself available to consult with and otherwise assist or provide general advice to our then Chief Executive Officer and to our Board of Directors as and at such times as they may reasonably request during the two-year period after the date of termination of Mr. Szews’ employment. In consideration of the benefits provided to Mr. Szews in his employment agreement, Mr. Szews entered into a confidentiality and loyalty agreement whereby he agrees not to compete with us for a period of 18 months after the termination of his employment and to keep in confidence any proprietary or confidential information for a period of two years after the termination of his employment. Mr. Szews also agrees not to solicit our employees and to notify us before accepting employment with a competitor of ours for a period of 18 months after the termination of his employment. Under Mr. Szews’ employment agreement, “cause” is defined as follows: • • • • • • engaging in misconduct that is substantially injurious to us; engaging in any willful act or omission that materially injures our reputation, business or prospects; being convicted of a felony; consenting to an order of the SEC for a violation of the federal securities laws; failing to perform material duties in a competent and efficient manner, which failure is not due to illness or disability; becoming subject to a petition under the federal bankruptcy laws or any state insolvency law or having a receiver appointed; failing to file timely federal or state income tax returns and to pay related taxes; being involved in the commission of an impropriety involving our financial statements; committing material violations of our codes of conduct; or materially breaching obligations under the confidentiality and loyalty agreement. • • • • Under Mr. Szews’ employment agreement, the term “good reason” means any substantial breach by us of the employment agreement that we do not remedy promptly after receipt of notice thereof from Mr. Szews.

Proposal 3 ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS As noted in the preceding discussion, executive compensation is an important matter both to us and to our shareholders. As a reflection of this importance and pursuant to SEC rules, we offer our shareholders the opportunity to approve, on a non-binding, advisory basis, the compensation of our named executive officers. Accordingly, we are seeking input from shareholders with this advisory vote on the compensation of our named executive officers as disclosed in the Compensation Discussion and Analysis section and the accompanying compensation tables contained in this Proxy Statement in accordance with the SEC’s executive compensation disclosure rules. The Human Resources Committee has overseen the development and implementation of our executive compensation programs. We have designed our compensation programs to directly link a significant portion of the compensation of our named executive officers to defined performance standards that promote balance between the drive for near-term growth and long-term increase in shareholder value. The Committee also designed our compensation programs to attract, retain and motivate key executives who are essential to the implementation of our strategic growth and critical to the success of our MOVE strategy. The Human Resources Committee bases its executive compensation decisions on our core compensation principles, including the following: • • motivating our executives to perform with shareholders’ interests in mind; assembling and maintaining a senior leadership team with the skills necessary to successfully execute our MOVE strategy, maintain our competitiveness, and continue increasing the long-term market value of our Company; and balancing awards earned for short-term results with awards earned for strategic decisions that we expect will sustain our long-term performance and deliver the results outlined in our MOVE strategy. • We believe our existing compensation programs have been effective at motivating our key executives to achieve superior performance and results for our Company, aligning compensation with our financial performance results, giving our executives an ownership interest in our Company so their interests are aligned with our shareholders, and enabling us to attract and retain talented executives whose services are in key demand in our industry and market sectors. We continued to meet these objectives in fiscal year 2015. With our core compensation principles in mind, the Human Resources Committee took or implemented the following actions in fiscal year 2015: • • approved modest base salary increases for our named executive officers in line with competitive market trends; structured our annual cash incentive awards for fiscal year 2015 with aggressive operating income targets that supported MOVE earnings per share targets set in fiscal year 2012; maintained each executive’s threshold, target and maximum annual cash incentive award payment levels expressed as a percentage of base salary, which targets the 50th percentile of the market; moved the approval of long-term equity awards from September 2015 to November 2015 (fiscal year 2016) to align the equity grant with the approval of other key compensation elements (base salary and annual incentives) for our executive officers, which resulted in the ability to approve total direct compensation at one time; continued to significantly limit the payout amount under new severance agreements that we enter into with our executive officers; and continued to limit the number and value of personal benefits. • • • • Compensation actions like these demonstrate our philosophy of aligning executive compensation with our financial performance and the marketplace, and increasing long-term shareholder value. We will continue to design and implement our executive compensation programs and policies in line with this philosophy to promote superior performance results and generate greater value for our shareholders. Our MOVE objectives will continue to influence these decisions. We urge shareholders to read the Compensation Discussion and Analysis section and the accompanying compensation tables contained in this Proxy Statement, which provide detailed information on the compensation of our named executive officers. The Human Resources Committee and our Board believe that the executive compensation program is effective OSHKOSH CORPORATION 2015 Proxy Statement 57

PROPOSAL 3: | Advisory Vote on the Compensation of Our Named Executive Officers in achieving our goals and that the compensation of our named executive officers has supported and contributed to our success. The Board hopes shareholders will support the compensation of our named executive officers as disclosed in the Compensation Discussion and Analysis section and the accompanying compensation tables contained in this Proxy Statement. Accordingly, the Board recommends that shareholders vote in favor of the following resolution: “RESOLVED, that the shareholders approve, on an advisory basis, the compensation of the named executive officers as disclosed pursuant to Item 402 of Regulation S-K, including in the Compensation Discussion and Analysis section and compensation tables and narrative discussion contained in this Proxy Statement.” This advisory vote on the compensation of our named executive officers is not binding on us, the Board, or the Human Resources Committee. However, the Board and the Human Resources Committee will review and consider the outcome of this advisory vote when making future compensation decisions for our named executive officers. named executive officers as disclosed in the Compensation Discussion OSHKOSH CORPORATION 2015 Proxy Statement 58 FOR The Board of Directors recommends a vote FOR the compensation of our and Analysis section and accompanying compensation tables contained in this Proxy Statement.

Such shareholder’s name, address, and number of shares of Common Stock held may be obtained by a shareholder on written request to our Secretary. PROXY ACCESS FOR SHAREHOLDERS RESOLVED: Shareholders ask our board of directors to adopt, and present for shareholder approval, a “proxy access” bylaw. Such a bylaw shall require the Company to include in proxy materials prepared for a shareholder meeting at which directors are to be elected the name, Disclosure and Statement (as defined herein) of any person nominated for election to the board by a shareholder or group (the “Nominator”) that meets the criteria established below. The Company shall allow shareholders to vote on such nominee on the Company’s proxy card. The number of shareholder-nominated candidates appearing in proxy materials shall not exceed 25% of the directors then serving. This bylaw, which shall supplement existing rights under Company bylaws, should provide that a Nominator must: a) have beneficially owned 3% or more of the Company’s outstanding common stock continuously for at least three years before submitting the nomination; b) give the Company, within the time period identified in its bylaws, written notice of the information required by the bylaws and any Securities and Exchange Commission rules about (i) the nominee, including consent to being named in the proxy materials and to serving as director if elected; and (ii) the Nominator, including proof it owns the required shares (the “Disclosure”); and c) certify that (i) it will assume liability stemming from any legal or regulatory violation arising out of the Nominator’s communications with the Company shareholders, including the Disclosure and Statement; (ii) it will comply with all applicable laws and regulations if it uses soliciting material other than the Company’s proxy materials; and (iii) to the best of its knowledge, the required shares were acquired in the ordinary course of business and not to change or influence control at the Company. The Nominator may submit with the Disclosure a statement not exceeding 500 words in support of the nominee. The Board shall adopt procedures for promptly resolving disputes over whether notice of a nomination was timely, whether the Disclosure and Statement satisfy the bylaw and applicable federal regulations, and the priority to be given to multiple nominations exceeding the one-quarter limit. The SEC’s proxy access Rule 14a-11 (https://www.sec.gov/rules/final/2010/33-9136.pdf), which was to apply to all companies subject to SEC proxy rules, was unfortunately vacated after a 2011 decision in Business Roundtable v. SEC. Therefore, proxy access rights must be established on a company-by-company basis. Subsequently, CFA Institute’s Proxy Access in the United States: Revisiting the Proposed SEC Rule <http://www.cfainstitute.org/learning/products/publications/ ccb/Pages/ccb.v2014.n9.1.aspx?WPID=BrowseProducts> (http://www.cfapubs.org/doi/pdf/10.2469/ccb.v2014.n9.1) performed a cost-benefit analysis and found that proxy access would: • “Benefit both the markets and corporate boardrooms, with little cost or disruption.” • Has the potential to enhance board performance, raising US market capitalization by up to $140 billion.

PROPOSAL 4: | Proxy Access for Shareholders — Proposal 4 Please vote to protect shareholder value: PROXY ACCESS FOR SHAREHOLDERS — PROPOSAL 4 Recommendation of the Board of Directors AGAINST Proposal 4 The Board of Directors has carefully considered this proposal and recommends a vote AGAINST this proposal. As we discuss below, we have already implemented proxy access for Oshkosh shareholders. Accordingly, our Board believes no further action is needed and that the form of proxy access that the shareholder proposal seeks is not in the best interest of our Company or our shareholders. Over the past several years, the Board has monitored developments on proxy access as part of its annual review of developments relating to governance matters. Recently, we reviewed the voting records of our twenty largest shareholders on the subject of proxy access and we sought direct input on the subject from shareholders who held, in the aggregate, more than 20% of our outstanding Common Stock to help inform our view on the shareholder proposal. This shareholder proposal is based, in part, on a “proxy access” rule adopted by the SEC in 2010. That rule was struck down by a federal court on the basis that the SEC had not adequately analyzed the costs to U.S. companies of managing contested board elections and did not support its claim that the rule would improve shareholder value and board performance. This shareholder proposal presents a “one size fits all” set of terms that might be submitted to companies of widely varying profitability, sizes, industries and shareholder bases. It is clear that no consideration was given to tailoring the proposal to the specific circumstances of our Company. Our Board believes that, when properly structured, proxy access can enhance shareholder ability to participate in director elections, which can have the potential of enhancing board accountability and responsiveness. This is why our Board recently adopted a proxy access by-law. Our Board recognized that accessing the proxy statement and proxy card is a serious, and potentially disruptive, event and should therefore include appropriate protections and be available only to a critical mass of long-term investors. Our Board believes this shareholder proposal is not properly structured to (1) minimize the potential for abuse by investors who lack a meaningful long-term interest in our Company or who wish to promote special interests that are not aligned with the interests of our other shareholders and (2) minimize disruption of Board functions and effectiveness. reasons: OUR BOARD RECOMMENDS A VOTE AGAINST THIS PROPOSAL FOR THE FOLLOWING REASONS: • Our Board of Directors has already adopted proxy access for the benefit of all shareholders. Due to the interest of our shareholders in proxy access, our Board considered various potential formulations of proxy access, including the provisions that the shareholder proposal advocates, taking into account feedback from some of our shareholders, the level of ownership and nature of our larger shareholders and the size, tenure and structure of our Board. Based upon our Board’s assessment of the relative advantages and disadvantages to our shareholders and our Company of the various proxy access formulations, in November 2015, our Board amended our by-laws to implement proxy access in the form it believes is most appropriate for our Company and our shareholders. Under the by-law provisions that the Board adopted, any shareholder or group of up to 20 shareholders that beneficially owns at least 5% of our outstanding Common Stock continuously for three years is permitted to nominate candidates for election to the Board and to require the Company to list such nominees along with the Board’s nominees in the Company’s proxy statement. For purposes of this limitation, a group of funds under common management and investment control is treated as one shareholder. The qualifying shareholder or group of shareholders may nominate up to 20% of the Board, OSHKOSH CORPORATION 2015 Proxy Statement 60 AGAINST Our Board recommends a vote AGAINST this proposal for the following

PROPOSAL 4: | Our Board recommends a vote AGAINST this proposal for the following reasons: rounding down to the nearest whole number of Board seats, but not less than two, under the proxy access provisions of the by-laws. We have an established record of strong governance practices. In considering the shareholder proposal, our Board encourages shareholders to consider proxy access in the context of other provisions already included in our Company’s articles of incorporation, by-laws, Corporate Governance Guidelines and other practices that promote accountability of management and our Board to our Company’s investors and engagement with shareholders. These include: • – We actively review and refresh our Board of Directors. Since 2010, we have added eight new independent directors who have brought valuable and varied experience in distinct and critical areas of our businesses, each providing a fresh perspective on our Board; The fully-independent Governance Committee annually evaluates the Board and, in making decisions on the Board’s composition, considers the tenure, performance, contributions, experience, skill set, and commitment of each director; Annual elections of all directors; Our by-laws and Corporate Governance Guidelines that provide that our Chairman of the Board must be an independent director in accordance with the listing standards of the New York Stock Exchange (NYSE) and one who has not previously served as an executive officer of our Company; Majority voting under which, in uncontested director elections, a director who does not receive a majority of the votes cast must submit his or her resignation; A process for shareholders to submit recommendations of director candidates for consideration by the Governance Committee; A process for shareholders to make nominations of director candidates and present proposals at our Company’s annual meeting, subject to conditions set forth in the by-laws; The ability of shareholders to call special meetings of shareholders at which they may remove and replace directors or propose other business; No supermajority voting requirements in our Company’s articles of incorporation or by-laws; No “poison pill”; Share ownership guidelines for our directors and executive officers; With the exception of the CEO, all of our directors are independent; Active shareholder engagement through which we regularly seek input from shareholders representing at least 50% of outstanding shares; To enhance their alignment with the interests of our long-term shareholders, our practice of annually granting shares of stock to our non-employee directors, which stock awards have been targeted at the 50th percentile of Towers Watson data for non-employee director compensation; Our stock ownership guidelines that apply to non-employee directors to ensure that our non-employee directors have a direct stake in the oversight and development of our Company by becoming shareholders; Long-term compensation of our executive officers consisting solely of equity-based incentive awards. We structure these awards to reward executives when we achieve long-term shareholder value. We believe these awards help ensure that executives consider the interests of our shareholders when they make long-term strategic decisions; An annual advisory vote on executive compensation; and The opportunity of shareholders to communicate with our Board. – – – – – – – – – – – – – – – – – We discuss under “Background to Board’s Recommendation for Director Nominees” and “Director Criteria, Background and Experience” on page 10, the process that the Governance Committee undertakes in assessing the qualifications and skills of a candidate for the Board. Nominees for director are selected on the basis of broad experience; wisdom; integrity; ability to make independent analytical inquiries; understanding of our Company’s business environment; and willingness and ability to devote adequate time to Board duties. Board members are expected to rigorously prepare for, attend, and participate in all Board and applicable Committee meetings. The Governance Committee is responsible for assessing the appropriate balance of skills and characteristics required of Board members. Our Board is committed to a diversified membership, in terms of both the individuals involved and their various experiences and areas of expertise. Our Board is also committed to regular refreshment of the Board, including adding two new independent directors since June 30, 2015 and a total of eight new independent directors since 2010. As a result of these processes, we have added new directors to our Board as our Company’s operations have evolved, while we have also retained directors with deep understanding of our Company’s background, growth, and past successes. By evaluating all of these factors, the Governance Committee has developed a Board comprised of highly successful, innovative, and independent directors who effectively oversee our Company’s management and operations. We maintain an open director nomination process OSHKOSH CORPORATION 2015 Proxy Statement 61

PROPOSAL 4: | Our Board recommends a vote AGAINST this proposal for the following reasons: accessible to all shareholders, and historically our shareholders have consistently supported our directors nominated by our Board. In addition to these governance practices, which promote responsiveness to shareholder concerns, our Board has a strong record of being active and engaged and building long-term shareholder value. Our Board is fully open to considering shareholder views and potential nominees, and our Company regularly solicits the views of our major shareholders on governance matters, including proxy access, and will continue to do so. Our Company’s shareholders already have an effective voice in director selection, election, and accountability, and have consistently elected our director nominees. The version of proxy access that the shareholder proposal advocates is unnecessary and could be detrimental to shareholders as a whole. In selecting the appropriate proxy access terms, our Board sought to balance the desire to provide meaningful rights to shareholders who we believe are generally representative of our other long-term shareholders against the potential harm to Board effectiveness that may be caused by the nomination of directors who may pursue narrow special interests, including interests unrelated to long-term shareholder value. We believe a 5% ownership level, as opposed to the 3% ownership level in the shareholder proposal, is more effective at balancing these competing goals, particularly when up to 20 shareholders (counting for this purpose a group of funds under common management and investment control as one shareholder) may aggregate their stockholdings to reach the 5% ownership threshold. Allowing a lower ownership threshold or an unlimited number of holders to act as a group undermines the principle that we believe most of our shareholders share: that the right to nominate a director using our Company’s proxy statement should be available only for those who have a sufficient financial stake in our Company to cause their interests to be aligned with the interests of the shareholders as a whole. For these reasons, our Board believes that our Company’s current proxy access right is in the best interests of our shareholders and that the approach in the shareholder proposal is not appropriate for our Company. • Our Board believes the proxy access by-law that it adopted provides a greater ability to foster the substantial long-term shareholder value that we believe we can deliver to shareholders. ACCORDINGLY, OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “AGAINST” THIS SHAREHOLDER PROPOSAL REGARDING PROXY ACCESS. OSHKOSH CORPORATION 2015 Proxy Statement 62

ATTACHMENT A | Non-GAAP Financial Measures Our Company reports its financial results in accordance with generally accepted accounting principles (GAAP) in the United States of America. Our Company is presenting various operating results, such as operating income, income from continuing operations, and earnings per share from continuing operations, both on a reported basis and on a basis excluding items that affect comparability of operating results. When our Company uses these measures, they are considered non-GAAP financial measures. We believe excluding the impact of certain items is useful to investors to allow a more accurate comparison of our Company’s operating performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our Company’s results prepared in accordance with GAAP. The table below presents a reconciliation of our Company’s presented non-GAAP measures to the most directly comparable GAAP measures (in millions, except per share amounts): Fiscal Year Ended September 30, 2015 2012 Defense Segment: Non-GAAP defense segment operating income OPEB curtailment gain GAAP defense segment operating income Consolidated: Non-GAAP operating income Workforce reduction charges OPEB curtailment gain GAAP operating income Non-GAAP income from continuing operations attributable to Oshkosh Corporation, net of tax Debt extinguishment costs, net of tax Pension and OPEB curtailment/settlement, net of tax Workforce reduction charges, net of tax GAAP income from continuing operations attributable to Oshkosh Corporation, net of tax Non-GAAP earnings per share attributable to Oshkosh Corporation from continuing operations-diluted Discrete tax items Debt extinguishment costs, net of tax Pension and OPEB curtailment/settlement, net of tax Workforce reduction charges, net of tax Tender offer and proxy contest costs, net of tax Performance share valuation adjustment GAAP earnings per share attributable to Oshkosh Corporation from continuing operations-diluted $5.8 3.4 $9.2 $398.1 (2.9) 3.4 $398.6 $239.1 (9.3) 2.1 (2.4) $229.5 $3.02 — (0.12) 0.03 (0.03) — — $2.30 0.49 — (0.02) — (0.05) (0.05) $2.90 $2.67 OSHKOSH CORPORATION 2015 Proxy Statement 63
