VOTING YOUR SHARES

Stockholders who owned the Company’s common stock at the close of business on March 15, 2016, the record date, may attend and vote at the annual meeting of stockholders, or the Annual Meeting. Each share is entitled to one vote. There were 38,665,434 shares of common stock outstanding on the record date.

How do I vote?

• You may vote by mail if you hold your shares in your own name

You do this by completing, signing and dating your proxy card and mailing it in the enclosed prepaid and addressed envelope.

• You may vote in person at the meeting

We will pass out ballots to any record holder who wants to vote at the meeting. However, if you hold your shares in “street name,” you must request a proxy from your bank, broker or other nominee in order to vote at the meeting. Holding shares in street name means you hold them through a bank, broker or other nominee, and as a result, the shares are not held in your individual name but through someone else.

If you hold your shares in "street name," you should follow the instructions provided by your bank, broker or other nominee, which may include instructions regarding your ability to vote by telephone or through the Internet.

How do I vote my shares held in the WEX Inc. Employee Savings Plan?

If you participate in our WEX Inc. Employee Savings Plan, commonly referred to as the "401(k) Plan," shares of our common stock equivalent to the value of the common stock interest credited to your account under the plan will be voted by the trustee in accordance with your instructions, if it is received by May 10, 2016. Otherwise, if you do not provide instruction by such date, the share equivalents credited to your account will not be voted by the trustee.

Please refer to the "Information about Voting Procedures" section.

THE BOARD OF DIRECTORS

BOARD LEADERSHIP

Our Board is led by our Chairman, Mr. Dubyak. As Chairman he leads all meetings of the Board at which he is present, sets meeting schedules and agendas and manages information flow to the Board to ensure appropriate understanding and discussion regarding matters of interest or concern to the Board. The Chairman also has such additional powers and performs such additional duties consistent with organizing and leading the actions of the Board as may be prescribed by the Board.

In addition to our Chairman, the Board has appointed Dr. Moriarty as our Vice Chairman and Lead Director. Dr. Moriarty chairs meetings of the independent directors in executive session and chairs any meetings at which the Chairman is not present. In addition, he facilitates communications between other members of the Board and the Chairman as needed. The Lead Director is authorized to call meetings of the independent directors and is available to consult with any of the Company’s senior executives regarding any concerns an executive may have. Dr. Moriarty aids in the preparation of meeting agendas and is authorized to meet with stockholders as a representative of the independent directors. Our Board decided to separate the roles of the Chairman and Chief Executive Officer because it believes that leadership structure presently offers the following benefits:

•Enhances our Board's objective evaluation of our Chief Executive Officer

•Frees the Chief Executive Officer to focus on the Company's operations instead of Board administration

•Provides the Chief Executive Officer with an experienced sounding Board

•Provides greater opportunities for communication between stockholders and our Board

THE BOARD’S ROLE IN RISK OVERSIGHT

Our Board oversees our risk management processes directly, and through a risk management program overseen by the Company’s Senior Vice President, General Counsel and Corporate Secretary, who reports directly to the Chief Executive Officer. Risks are identified and prioritized by our management, and a report of those risks is presented to the full Board. In general, our Board oversees risk management activities relating to business strategy, operations and financial and legal risks; our Audit Committee oversees the process by which various issues, such as enterprise risk and cybersecurity, are managed and reported to the Board, as well as activities related to financial controls and legal and corporate compliance; and, our Compensation Committee oversees risks related to our compensation programs. Oversight of particular risks may also be delegated to other committees of the Board as appropriate, based upon the nature of any particular risk. Our appointment of both: (i) a Chairman and (ii) Vice Chairman and Lead Director allows for an efficient delegation of responsibilities for risk oversight amongst those two individuals as well as the use of an independent Vice Chairman and Lead Director to manage risks as needed.

MEMBERS OF THE BOARD OF DIRECTORS

The Corporate Governance Committee seeks directors with the following types of experience:

Finance, accounting, or reporting experience. Directors with an understanding of finance and financial reporting processes are valued on our Board because of the importance we place on accurate financial reporting and robust financial controls and compliance. We also seek to have a number of directors who qualify as audit committee financial experts.	Global or international business experience. Because our company is a global organization, directors with broad international exposure provide useful business and cultural perspectives. We seek directors who have had relevant experience with multinational companies or in international markets.
Legal or regulatory experience. Directors who have had legal or regulatory experience provide insights into addressing significant legal and public policy issues, particularly in areas related to our company’s business and operations. Because our company’s business requires compliance with a variety of regulatory requirements across a number of countries, our Board values directors with relevant legal or regulatory experience.	Leadership experience. We believe that directors who have held significant leadership positions over an extended period, especially CEO positions, provide the company with unique insights. These people generally possess extraordinary leadership qualities, and the ability to identify and develop those qualities in others. They demonstrate a practical understanding of organizations, processes, strategy and risk management, and know how to drive change and growth.
Business development and M&A experience. Directors with a background in business development and in M&A provide insight into developing and implementing strategies for growing our business. Useful experience in this area includes skills in analyzing the “fit” of a proposed acquisition with a company’s strategy, the valuation of transactions, and assessing management’s plans for integration with existing operations.	Technology experience. As a technology company and leading innovator, we seek directors with backgrounds in technology and cybersecurity because our success depends on developing, investing in and protecting new technologies and ideas.
Marketing or public relations experience. Directors, who have had relevant experience in marketing, brand management, and public relations, especially on a global basis, provide important insights to our Board.	Industry experience. We seek to have directors with experience in the payments, travel and healthcare industries in which we participate.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

No member of our Compensation Committee (the members of which are listed in the table in the "Board and Committee Meetings" section) is or was one of our or our subsidiaries’ former officers or employees. During 2015, there were no Compensation Committee interlocks as required to be disclosed under SEC rules.

DIRECTOR COMPENSATION

The Company's Non-Employee Directors Compensation Plan is designed to achieve the following objectives:

• Attract and engage directors

• Compensate our directors for the investment of time they make to support the Company

• Align director compensation with stockholder interests

• Have a compensation structure that is simple, transparent and easy for stockholders to understand

Annual Cash Retainers

The Company pays each non-employee board member the following annual cash retainer(s) based upon his or her service. Such payments are made in four equal quarterly amounts.

Annual Chair Cash Retainer	$	87,500
Annual Lead Director Cash Retainer	$	75,000
Annual Director Cash Retainer (other than Chairman and Lead Director)	$	50,000
Audit Committee Chair Cash Retainer	$	30,000
Compensation Committee Chair Cash Retainer	$	20,000
Finance Committee Chair Cash Retainer	$	20,000
Governance Committee Chair Cash Retainer	$	15,000

Finance Committee Member Cash Retainer (other than Committee Chair)	$	10,000
Governance Committee Member Cash Retainer (other than Committee Chair)	$	7,500

To the extent a director is appointed at a time other than the annual stockholders' meeting, any annual cash retainer is prorated. Employees who serve as directors are not separately compensated for their service on our Board.

Equity Retainers

In 2015 all non-employee directors were granted a number of restricted stock units, or RSUs, worth the equivalent of approximately $110,000 at the time of the annual stockholders’ meeting at the then current stock price. The Lead Director was granted additional RSUs worth the equivalent of approximately $25,000 and the Chairman was granted additional RSUs worth the equivalent of approximately $37,500 at the time of the annual stockholders’ meeting at the then current stock price. These RSUs vest on the first anniversary of the date of grant.

New Director Equity Grants

All new directors are granted a number of RSUs, worth the equivalent of $50,000 at the then current stock price. Such RSUs vest annually and are granted at the next annual stockholders meetings after the appointment.

Mr. Dubyak was not compensated under the non-employee Director Compensation Plan until April 1, 2015 as he remained an employee of the Company until that date. From January 1, 2015 until March 31, 2015, Mr. Dubyak was paid advisory fees at the rate of $49,342 per month for service as an Executive Chairman. Commencing on April 1, 2015, Mr. Dubyak was paid in accordance with the non-employee Director Compensation Plan as described above.

Fee Deferral

Directors may defer all or part of their cash fees and equity retainers into deferred stock units which will be payable in Company shares to the director 200 days following cessation of Board service.

Expense Reimbursement

Directors are reimbursed by the Company for their out-of-pocket travel and related expenses incurred in attending all Board and committee meetings.

NON-EMPLOYEE DIRECTOR OWNERSHIP GUIDELINES

The Compensation Committee has established equity ownership guidelines for all non-employee directors. "Equity" for the purpose of these guidelines is defined to include shares of the Company’s common stock, vested restricted stock units and deferred stock units. Under the guidelines of the equity ownership program, all directors are expected to own equity equal in value to at least three times each director’s annual director cash retainer or lead director cash retainer. New directors have three years following their appointment to the Board to achieve this level of ownership. The Compensation Committee assesses progress against the guidelines each year on July 31. As of July 31, 2015, all of our non-executive directors, other than Mr. Duprat who joined the Board on March 12, 2014, exceeded the holding levels in the guidelines. Under our guidelines, Mr. Duprat has three years from the date of joining the Board to accumulate sufficient equity to gain compliance with the equity ownership guidelines.

DIRECTOR INDEPENDENCE

We have considered the independence of each member of the Board. To assist us in our determination, we reviewed the NYSE independence requirements and our general guidelines for independence, which are part of our corporate governance guidelines.

To be considered independent: (1) a director must be independent as determined under Section 303A.02(b) of the NYSE Listed Company Manual and (2) in the Board’s judgment, the director must not have a material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company).

The Board has established guidelines to assist it in determining whether a director has a material relationship with the Company. Under these guidelines, a director will not be considered to have a material relationship with the Company if (1) he or she is independent as determined under Section 303A.02(b) of the NYSE Listed Company Manual and (2) he or she: (i) serves as an executive officer of another company which is indebted to the Company, or to which the Company is indebted, provided that the total amount of either company's indebtedness to the other is less than one percent of the total consolidated assets of the company he or she serves as an executive officer; (ii) serves as an officer, director or trustee of a tax exempt organization, that receives contributions from the Company, provided that the Company's discretionary contributions to such organization are less than the greater of $1 million or 2 percent of that organization’s consolidated gross revenues; or (iii) serves as a director of another company with which the Company engages in a business transaction or transactions, provided that the director owns less than 5 percent of the equity interests of such other company and recuses himself or herself from deliberations of the Board with respect to such transactions. In addition, ownership of a significant amount of the Company's stock, by itself, does not constitute a material relationship. For relationships not covered by the guidelines set forth above, the determination of whether a material relationship exists shall be made by the other members of the Board of Directors who are independent as defined above.

Based on our guidelines and NYSE corporate governance standards, we have determined that the following directors are independent: Eric Duprat, Shikhar Ghosh, Ronald T. Maheu, George L. McTavish, Rowland T. Moriarty, Kirk P. Pond, Regina O. Sommer and Jack VanWoerkom. In assessing the independence of Mr. VanWoerkom, the Board considered the employment relationship of an immediate family member of Mr. VanWoerkom who is not an executive officer and receives annual compensation of less than $120,000.

In addition, each of the members of the Corporate Governance Committee, Audit Committee and the Compensation Committee are independent, as determined by the Board in accordance with its guidelines and the listing standards of the NYSE. We have also determined that the members of the Audit Committee satisfy the independence requirements contemplated by Rule 10A-3 under the Exchange Act, and that the members of the Compensation Committee satisfy the independence requirements contemplated by Rule 10C-1 under the Exchange Act.

DIRECTOR NOMINATIONS AND RECOMMENDATIONS

The Corporate Governance Committee responsibilities include recommending candidates for nomination to the Board. The Corporate Governance Committee has recommended Messrs. Ghosh and Pond (with Mr. Ghosh abstaining from the vote regarding his own nomination) and Ms. Smith for re-election at the 2016 Annual Meeting. Messrs. Ghosh and Pond have served as members of our Board since February 2005 and Ms. Smith has served since January 2014. In identifying potential directors, the Corporate Governance Committee may: retain a search firm; canvass their networks; evaluate highly-regarded leaders in industry and academia; or, entertain suggestions from stockholders or other business organizations, among other ways suitable for identifying potential directors.

The Corporate Governance Committee will consider candidates nominated or recommended by stockholders as potential director nominees in the same manner as candidates identified by the Corporate Governance Committee. If the Board determines to nominate a stockholder-recommended candidate and recommends his or her election, then that nominee’s name will be included in the proxy card for the next annual meeting. Our stockholders also have the right under our By-Laws to directly nominate director candidates and should follow the procedures outlined in the “Information About Voting Procedures” section of this proxy statement in the answer to the question entitled "How do I submit a stockholder proposal or director nominee for next year's annual meeting or suggest a candidate for nomination as a director to the Corporate Governance Committee?"

To be timely, a stockholder's notice to the Secretary of a director nominee for next year's annual meeting must be delivered to or mailed and received no earlier than January 14, 2017 nor later than February 13, 2017. However, in the event that the annual meeting is called for a date that is not within 25 days before or after May 13, 2017, notice by the stockholder must be received no earlier than 120 days prior to the annual meeting and no later than the later of the 90th day prior to the

14

annual meeting or the tenth day following the day on which notice of the date of the annual meeting is mailed or publicly disclosed.

Stockholder nominations must be addressed to:

    WEX Inc.

    Attention: Corporate Secretary

    97 Darling Avenue

    South Portland, ME 04106

Director Qualifications

The qualifications for directors are described in our Corporate Governance Guidelines and the guidelines for evaluating director nominees are in the Corporate Governance Committee's charter, each of which is available on our website. The Corporate Governance Committee believes that a nominee for the position of director must meet the following specific, minimum qualifications:

• Nominees should have a reputation for integrity, honesty and adherence to high ethical standards;

• Nominees should have demonstrated business acumen, experience and ability to exercise sound judgments in matters that relate to the current and long-term objectives of the Company and should be willing and able to contribute positively to the decision-making process of the Company;

• Nominees should have a commitment to understand the Company and its industry and to regularly attend and participate in meetings of the Board and its committees;

• Nominees should have the interest and ability to understand the sometimes conflicting interests of the various constituencies of the Company, which include stockholders, employees, customers, governmental units, creditors and the general public, and to act in the interests of all stockholders; and

• Nominees should not have, nor appear to have, a conflict of interest that would impair the nominee's ability to represent the interests of all the Company's stockholders and to fulfill the responsibilities of a director.

Our Corporate Governance Committee does not have a policy with respect to diversity, but believes that our Board, taken as a whole, should embody a diverse set of skills, experiences and backgrounds. Our Board currently is comprised of ten directors, two of whom are women and another of whom is South Asian. The Corporate Governance Committee intends to be mindful of diversity, with respect to gender, race and national origin, in connection with future nominations of directors not presently serving on the Board. In addition, our Corporate Governance Committee’s charter provides that nominees shall not be discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability or any other basis proscribed by law.

Application of Criteria to Existing Directors

The re-nomination of existing directors is not viewed as automatic, but is based on continuing qualification under the criteria listed above. The Committee uses its best judgment and discretion in applying the criteria to the existing directors keeping in mind the interest of the Company.

In addition, the Corporate Governance Committee considers the existing directors' performance on the Board and any committee, including consideration of the extent to which the directors undertook continuing director education.

The backgrounds and qualifications of the directors considered as a group provide a significant breadth of experience, knowledge and abilities in order to assist the Board in fulfilling its responsibilities. The rationale for the Company's determination that each director is well suited to serve on the Board is specified with his or her respective biographical entry under the "Members of the Board of Directors" section of this proxy statement.

15

COMMUNICATIONS WITH THE BOARD OF DIRECTORS

The Board believes that the Chief Executive Officer and her designees, as well as the Chairman of the Board and Vice Chairman and Lead Director, speak for the Company. Individual Board members may, from time to time, meet or otherwise communicate with various constituencies who are involved with the Company. It is, however, expected that Board members would do so with the knowledge of and, absent unusual circumstances or as contemplated by the committee charters, only at the request of the Company’s senior executives or the Board.

The Board will give appropriate attention to written communications that are submitted by stockholders and other interested parties, and will respond if and as appropriate. Absent unusual circumstances or as contemplated by the committee charters, the Vice Chairman and Lead Director shall, subject to advice and assistance from the General Counsel, (1) be primarily responsible for monitoring communications from stockholders and other interested parties, and (2) provide copies or summaries of such communications to the other directors as he considers appropriate.

If you wish to communicate with the Board or the independent members of the Board, you may send your communication in writing to:

    Independent Director Communication

    WEX Inc.

    Attention: Corporate Secretary

    97 Darling Avenue

    South Portland, ME 04106

You should include your name and address in the written communication and indicate whether you are a stockholder.

Governance Disclosures on Our Website

Complete copies of our corporate governance guidelines, committee charters and code of conduct are available on the Corporate Governance section of our website, at www.wexinc.com. In accordance with NYSE rules, we may also make disclosure of the following on our website:

• the identity of the Lead Director at meetings of independent directors;

• the method for interested parties to communicate directly with the Lead Director or with the independent directors as a group;

• the identity of any member of our Audit Committee who also serves on the audit committees of more than three public companies and a determination by our Board that such simultaneous service will not impair the ability of such member to effectively serve on our Audit Committee; and

• contributions by us to a tax exempt organization in which any independent director serves as an executive officer if, within the preceding three years, contributions in any single fiscal year exceeded the greater of $1 million or 2% of such tax exempt organization’s consolidated gross revenues.

COMPENSATION

ITEM 2. ADVISORY VOTE ON EXECUTIVE COMPENSATION

We are providing you with the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of the executive officers named in the Summary Compensation Table under "Executive Compensation," whom we refer to as our "named executive officers" or "NEOs," as disclosed in this proxy statement in accordance with the SEC’s rules. This proposal, which is commonly referred to as "say-on-pay

," is required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which added Section 14A to the Securities Exchange Act of 1934, or Exchange Act.

Our executive compensation programs are designed to attract, motivate, and retain our executive officers, who are critical to our success. The "Executive Compensation" section of this proxy statement, including the "Compensation Discussion and Analysis," describes in detail our executive compensation programs and the decisions made by the Compensation Committee with respect to the fiscal year ended December 31, 2015.

WEX’s philosophy regarding executive compensation is straightforward: reward our executives for their contributions to the Company’s annual and long-term performance by tying a significant portion of their total compensation to key drivers of increased stockholder value. Reflecting our pay-for-performance philosophy, a significant portion of executive compensation is performance-based, subject to increase when results exceed corporate targets, reduction when results fall below target and elimination if results do not achieve threshold levels of performance. Stockholders are urged to read the Compensation Discussion and Analysis section, beginning on page 19, of this Proxy Statement, which more thoroughly discusses how our compensation policies and procedures implement our compensation philosophy and objectives.

Our Board is asking stockholders to approve a non-binding advisory vote on the following resolution:

RESOLVED, that the compensation paid to WEX Inc.’s named executive officers, as disclosed in accordance with the Securities and Exchange Commission’s compensation disclosure rules, including the Compensation Discussion and Analysis, the compensation tables and any related material disclosed in this proxy statement, is hereby approved.

As an advisory vote, this proposal is not binding. The outcome of this advisory vote will not overrule any decision by the Company or the Board (or any committee of the Board), or create or imply any change or addition to the fiduciary duties of the Company or the Board (or any committee of the Board). However, our Compensation Committee and Board value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for named executive officers.

The Board has decided that the Company will hold an annual advisory vote on the compensation of our named executive officers.

We recommend a voteFORapproval of the compensation of our named executive officers.

Fleet Solutions reports on the same basis as the historical Fleet Payment Solutions business segment. Travel and Corporate Solutions includes the Travel business as well as other verticals. Health and Employee Benefit Solutions includes the Healthcare and Employee related businesses. This change will enhance the Company's transparency and align our reporting with how we now operate our business. The Fleet Solutions segment provides customers with fleet vehicle payment processing services specifically designed for the needs of commercial and government fleets, through a closed-loop network that offers complete control of the transaction life cycle. During 2015, Fleet Solutions revenue represented approximately 63 percent of our total revenue, Travel and Corporate Solutions represented approximately 23 percent of our total revenue, and Health and Employee Benefit Solutions represented approximately 14 percent of our total revenue. Our Travel and Corporate Solutions segment is comprised of our virtual and prepaid products that we use to provide innovative corporate purchasing and payment capabilities that can be integrated with our customers’ internal systems to streamline their corporate payments, accounts payable and reconciliation processes. Our Health and Employee Benefit Solutions segment is comprised of our healthcare payment products and SaaS platforms that we use to provide simplified payment capabilities in a complex healthcare market as well as employee benefit products in Brazil.

Our businesses focus on streamlining and modernizing payment environments to give customers greater control over their business, resulting in smarter decisions, lower operating costs, higher efficiency and greater customer satisfaction. Our business model enables us to provide exceptional payment security and control across a wide spectrum of payment sectors.

2015 Company Performance Highlights. Our 2015 results were significantly impacted by a steep decline in oil prices. While fuel price adjusted revenue (which we refer to as PPG Adjusted Revenue) grew 11% in 2015, adjusted net income (which we refer to as ANI), a non-GAAP measure, declined by 4% for the same period. Total Stockholder Return (TSR) was

19

also down on a one-year basis, as shown in the charts below. Adjusting for constant currency, fuel prices, fuel spreads, and impacts from our fuel price hedges, PPG Adjusted Revenue would have grown approximately 22% and ANI would have increased approximately 17% over 2014, demonstrating operational success in 2015. The reconciliation of the following measures to the respective GAAP measure is located in Appendix A to this proxy statement.

While our results were impacted by depressed fuel prices during 2015, we have designed our performance-based annual and long-term incentive awards for executives to, among other things, align compensation with performance against the metrics shown above. As a result, the payout factor for our 2015 short-term incentive plan and PSU awards was well below target, and stock options awarded in 2015 are currently underwater and will have no intrinsic value until our stock price experiences considerable appreciation.

Despite a volatile, declining fuel price environment, 2015 was a strong year operationally for WEX. We continued to execute against our strategy to grow organically and through mergers and acquisitions, further globalize our business, and drive scale across the organization. Several highlights of our achievements during 2015 in furtherance of our strategy included:

w	On November 18, 2015, our wholly- owned subsidiary Evolution1 acquired Benaissance, LLC, a leading provider of integrated SaaS technologies and services for healthcare premium billing, payment and workflow management, to complement our healthcare payments products and services.
w	On October 18, 2015, we entered into a purchase agreement to acquire Electronic Funds Source LLC ("EFS"), a provider of customized corporate payment solutions for fleet and corporate customers with a focus on the large and mid- sized fleet segments, for an aggregate purchase price comprised of $1.1 billion in cash and 4,011,672 shares of the Company’s common stock, subject to certain working capital and other adjustments as described in the purchase agreement.
w	On August 31, 2015, we acquired the remaining 49 percent ownership in UNIK S.A., a majority- owned subsidiary, prior to this transaction.
w	On January 7, 2015, we sold the operations of rapid! PayCard for $20.0 million, which resulted in a pre- tax book gain of $1.2 million.

Summary of WEX’s 2015 Executive Compensation Program. A summary of our executive compensation program during 2015 is provided below.

- Generally, we target total direct compensation (salary/ annual bonus/ long-term incentives) within a competitive range of the market median.

- Pay will vary above or below target based primarily on corporate and, to a lesser degree individual, quantitative performance outcomes.

Compensation Element	2015 Element
Base Salary Fixed rate of pay	Among NEOs, excluding the CEO, increases averaged 5%, reflecting market-based adjustments.
Short-term Incentive Plan ("STIP") Payout can range from 0-200% of target based on, corporate financial goals 1. Adjusted Net Income ("ANI") (50%) 2. PPG Adjusted Revenue (20%) 3. Adjusted Net Income Margin (15%) 4. Revenue Diversification (15%) The funded payout may be adjusted for each NEO (excluding the CEO) through an individual performance modifier, down to 75% or up to 125%, with no payout greater than 200% of target. The adjustment is made based on an assessment of performance versus pre-defined, often quantitative individual goals. The modifier, across our executive leadership team, is intended to generally function within the “pool” of STIP-funded dollars (0-200% of target) that is determined based on the four financial metrics listed above. The Committee has further discretion to eliminate any funded bonus payout at its discretion, should circumstance warrant.	STIP funding was 79% of target, based on objective performance against pre-defined enterprise-wide quantitative goals. Payments for our NEOs averaged 81% of target, after two non-CEO NEOs received a positive individual modifier.
Long-Term Incentive Plan ("LTIP") Our target mix for our NEOs (excluding our CEO) during 2015 was: 60% Performance Stock Units (PSUs). • Payout can range from 0-200% of target • 1-year performance goals; if earned, additional 2-year time-based vesting requirement • Goals weighted 60% ANI Earnings Per Share (EPS), and 40% PPG adjusted revenue 20% Stock Options (options). • 3-year vesting requirement • Reward long-term stockholder value creation 20% Restricted Stock Units (RSUs). • 3-year vesting requirement • Reward long-term stockholder value creation and encourage retention The mix for our CEO was: 60% PSUs, 25% stock options, and 15% RSUs, to further emphasize the importance of long-term stockholder value creation.	Payout of 2015 PSUs was 73% of target. Given the strategic importance of growing sales, we included a revenue performance measure in both our short-term and long-term incentive programs. PPG Adjusted Revenue reflects top line financial performance, which we believe is a strong indicator of our long-term ability to drive stockholder value.

21

Pay Mix. The majority of CEO compensation is variable (“at risk”). For 2015, 81% of target total direct compensation was variable for our CEO. This directly ties pay to company performance outcomes, including financial results, strategic initiatives, and stock price performance.

2015 CEO Pay Mix

The majority of the compensation for the remaining NEOs, is also variable and tied directly to Company performance outcomes, as described above.

Process for Determining Executive Compensation

Compensation Committee. The Compensation Committee, composed solely of independent directors and referred to in this CD&A as the Committee, is responsible for our executive officer compensation decisions. The Committee works closely with its independent consultant and management to examine pay and performance matters throughout the year. The Committee held 8 meetings over the course of 2015, all of which included an executive session without management present. The Committee charter may be accessed through the “Governance” link found on our website at: http://ir.wexinc.com/phoenix.zhtml?c=186699&p=irol-govhighlights.

In the first quarter of each fiscal year, the Committee reviews the Board’s assessment of the CEO's performance with the CEO and reviews the Company's results for the prior year. In addition, the Committee approves the following, as explained below:

•changes to executive base salaries and incentive targets, if any, for the current year;

•STIP payout, if any, for the previous fiscal year;

•STIP design and targets for the current fiscal year;

•vesting of performance-based restricted stock units granted under the LTIP, if any, for previous years; and

•LTIP metrics, targets and grants for the current fiscal year.

Agenda items for the second quarter vary each year but always include a review of Company performance and progress toward the achievement of incentive plan targets. Typically, this also includes a retrospective assessment of the senior executive pay versus performance relationship.

The Committee generally conducts its annual review of executive compensation in the third or fourth quarter of each year. The Committee is provided a report from its independent compensation consultant who compares the compensation of Company executives to a peer group of companies, details appropriate survey data and provides recommendations for compensation actions.

In the final quarter of each fiscal year, management generally presents the Committee with recommended executive compensation changes for each element of compensation.

The design of the STIP and LTIP is typically discussed over multiple meetings prior to the actual approval of the plans in the first quarter of each year. The discussions generally focus on the metrics to be utilized, the difficulty of the performance goals and the weightings for each metric. Other items that are addressed on an annual basis include a review of the Committee's charter, compliance with executive and director stock ownership guidelines, and a compensation-related risk assessment.

Executive Management. Our SVP, Human Resources and SVP and General Counsel, acting under the supervision of the CEO and working with members of our Human Resources, Legal and Finance departments, are responsible for coordinating and implementing executive compensation and discussing significant proposals or topics impacting executive compensation at WEX with the Committee. This includes development of compensation recommendations, in accordance with the compensation philosophy and policies more fully described elsewhere in this CD&A. The CEO, CFO, General Counsel and Corporate Secretary, SVP, Human Resources, and VP, Corporate Securities Counsel are invited to, and generally do, attend Committee meetings.

The Committee has exclusive authority for approving the compensation of the CEO and the other NEOs. The CEO meets with the Committee and the compensation consultant to discuss company and individual performance objectives and outcomes, and review compensation recommendations for executive officers directly reporting to her, including the other NEOs. Thereafter, the Committee meets privately with its independent compensation consultant to review and determine compensation of our CEO. In addition, the Committee sets the targets each year for compensation plan performance for our officers; management provides input and recommendations with respect to such targets, as well as information and analyses, as requested by the Committee.

Independent Compensation Consultant. The Committee has the authority to retain and terminate a compensation consultant, and to approve the consultant’s fees and all other terms of such engagement. During 2015, the Committee continued to directly retain Compensation Advisory Partners LLC ("CAP") as its independent compensation consultant. The scope of the work done by CAP for the Committee at its direction included:

• Preparing analyses and recommendations to inform the Committee’s decisions related to executive and director compensation;

23

• Providing updates on market trends and the regulatory environment, as they relate to executive and director compensation;

• Reviewing and commenting on management proposals presented to the Committee; and

• Working with the Committee to validate the pay-for-performance relationship, and support alignment with stockholders.

The Committee assessed the independence of CAP pursuant to SEC and NYSE rules, and concluded that no conflict of interest exists that would prevent CAP from providing independent advice to the Committee. CAP will not perform other services for WEX without the consent of the Chair of the Committee. CAP meets with the Committee Chair and the Committee outside the presence of management. In addition, CAP participates in all of the Committee’s meetings and, when requested by the Committee Chair, in preparatory meetings and executive sessions.

Total Compensation - Objectives and Philosophy

Objectives. Our compensation programs are designed and administered to balance the achievement of near-term operational results and long-term growth goals with the ultimate objective of increasing long-term stockholder value. The principal elements of an executive’s total compensation consist of: base salary, annual cash bonus, and long-term incentives.

Compensation Philosophy. Generally, we target total direct compensation (salary, annual bonus and long-term incentives) within a competitive range of the market median. Sustained performance may be recognized in individual pay components. Pay may vary above or below target based on actual performance outcomes. Variations in total direct compensation among the NEOs reflect differences in competitive pay for their respective positions as well as the size and complexity of the business units or functions they oversee, the performance of those business units or functions, and individual performance.

2015 Total Direct Compensation

We structure NEO total direct compensation so that the majority is delivered in the form of equity awards, in order to provide incentives to work towards growth of long-term profitability that will enhance stockholder returns and to align our NEOs' compensation directly with our stockholders' interests. We also structure NEOs’ cash compensation so that a significant portion is at risk under the company’s short-term incentive plan, payable primarily based on enterprise results, and to a lesser degree based on individual performance. We further detail each component of total direct compensation below.

Base Salary.  We review base salaries annually, but we do not necessarily award salary increases each year. In determining base salary levels for executive officers, the Committee considers the following qualitative and quantitative factors: job level and responsibilities, relevant experience, individual performance, recent corporate and business unit performance, internal equity, and our objective of paying competitive total direct compensation if performance is met. From time to time base salaries may be adjusted other than as a result of an annual review, in order to address competitive pressures or in connection with a promotion. Year-end NEO salaries were as follows:

24

Name	NEOs Base Salary			Rationale for Increase
	2014	2015	% Increase  (2014-2015)
Smith, Melissa D. CEO & President	$525,000	$565,000	8%	Market-based adjustment; below median
Elder, Steven A. SVP & CFO	$335,000	$335,000	—
Hogan, George W. SVP, International	$300,000	$308,000	3%	Market-based adjustment; below median
Janosick, Kenneth W. SVP and GM, Global Fleet Direct	—	$310,000	—	Not a NEO in 2014
Rapkin, Hilary A. SVP, General Counsel and Corporate Secretary	$325,000	$355,000	9%	Market-based adjustment; below median
		Average:	5%

Short-Term Incentive Plan ("STIP").  Our Annual Incentive Plan, structured under the 2015 Section 162(m) Performance Incentive Plan ("PIP"), is designed to motivate our NEOs to drive profitable company growth, while diversifying Company revenues, by measuring the NEOs performance against our plans at the corporate level, with the potential for individual adjustment for NEOs (excluding the CEO) as described below. The PIP was approved by our stockholders in 2015 and is designed to give us flexibility to potentially maximize the tax deductibility of certain incentives as performance-based awards under Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)), as further described below under the “Tax and Accounting Considerations” section.

We establish a cash bonus target for each executive officer based upon their position within the company, responsibility and competitive cash bonus opportunities for similar positions at other companies. Final actual payouts may range from 0% to 200% of the target bonus opportunity based on actual performance outcomes. The following tables describe 2015 NEO performance goals, results for each component of the bonus, and the actual cash bonus award for each NEO.

Company Goals	Threshold (50% payout)	Target Performance Goal (100% payout)	Maximum (200% payout)	Strategic Objective Weight	Actual Performance	Payout based on Actual 2015 Performance
Adjusted Net Income(1)(2)	$172,610,000	$202,444,000	$230,786,000	50%	$186,327,121	73%
PPG Adjusted Revenue(3)(4)	$845,489,000	$892,460,000	$937,082,000	20%	$866,046,646	71.9%
Pre-tax ANI Margin %(1)(3)	34%	36%	37%	15%	35%	72%
Revenue Diversification(2)(5)	$7,084,000	$11,807,000	$15,113,000	15%	$12,362,903	117%
Weighted Average Payout						79.2%

Company Goals

⁽¹⁾ Adjusted Net Income (“ANI”) means: Adjusted Net Income as reported in the Company’s Form 10-K filing reporting the Company’s results for the performance period (the “10-K ANI”). Notwithstanding the foregoing, in order to determine the level of performance for purposes of this Program, the Compensation Committee shall adjust the 10-K ANI by the following items (if any): losses from discontinued operations, budgeted income not realized post-closing date of divestitures, the cumulative effects of changes in Generally Accepted Accounting Principles, the results from non-budgeted acquisitions, any one-time charge or dilution resulting from any acquisition or divestiture, the effect of changes to our effective federal or state tax rates,

25

extraordinary items of loss or expense, any other unusual or nonrecurring items of loss or expense, including restructuring charges, and the related tax impacts.

⁽²⁾ Excludes impact of budgeted severance cost.

⁽³⁾ To the extent differences in foreign exchange rates impact PPG adjusted revenue and/or adjusted net income by more than 10% versus budgeted amounts, excess impacts are ignored for calculation impacts.

⁽⁴⁾ PPG Adjusted Revenue means: 2015 Revenue as reported in the Company’s Form 10-K filing reporting the Company’s results for the performance period adjusted for difference between reported 2015 PPG and Board-approved budgeted 2015 PPG of $2.62 for the US and $4.47 for Australia.

⁽⁵⁾ New sources of revenue including: fees (i.e. reactivation, paper, Truck Stop), currency conversion, return payments, media or other new vertical. Excludes impact of acquisitions.

The funded STIP payout, based on the four financial metrics and pre-set goals described above, may be adjusted for each NEO (excluding the CEO) through an individual performance modifier, down to 75% or up to 125%, with no payout greater than 200% of target. The adjustment is made based on an assessment of performance versus pre-defined, often quantitative individual goals. The modifier, across our executive leadership team, is intended to generally function within the “pool” of STIP-funded dollars (0-200% of target) that is determined based on the four financial metrics listed above. The pre-defined goals, which are generally quantitative, used to determine individual modifiers for the non-CEO NEOs were based on the following criteria:

• Steven Elder: Investor outreach, exposure to and management of foreign exchange rates, as well as general leadership competencies

• George Hogan: Contract signings, international strategy execution, as well as general leadership competencies

• Kenneth Janosick: Revenue per transaction, as well as general leadership competencies

• Hilary Rapkin: Expansion of legal and compliance model given growth in geographic footprint, talent development, expense control, as well as general leadership competencies

Our CEO makes individual modifier recommendations to our Committee for all of the other NEOs, for consideration and approval by the Committee. With respect to the 2015 individual performance modifiers outlined below, our CEO considered the following accomplishments during 2015:

• Steven Elder: No modifier was applied in the case of Mr. Elder.

• George Hogan: As a result of Ms. Smith’s overall assessment of Mr. Hogan’s success against his pre-defined individual goals, which included significant over-performance against international revenue and operating income objectives in 2015, a positive individual modifier (of +12%) was recommended by Ms. Smith for Mr. Hogan, as shown in the chart below.

• Kenneth Janosick: As a result of Ms. Smith’s overall assessment of Mr. Janosick’s successes against his pre-defined individual goals, especially with regard to his leadership of significant pricing initiatives, a positive individual modifier (of +8%) was recommended by Ms. Smith for Mr. Janosick, as shown in the chart below.

• Hilary Rapkin: No modifier was applied in the case of Ms. Rapkin.

As stated above, the individual modifier, across our executive leadership team, is intended to generally function within the “pool” of STIP funded dollars (0-200% of target) that is determined based on the four financial metrics listed above. Therefore, while no individual modifier or a positive individual modifier was applied across the NEO group, other members of the executive leadership team also received individual modifiers, including downward adjustments, to balance total incentive spend against STIP funded dollars.

Long-Term Incentive Compensation. The Company provides long-term equity-based incentives through the long-term incentive plan (“LTIP”). Grants under the LTIP were provided through a mix of PSUs, which vest from 0% to 200% based on the achievement of performance goals, subject to further service-based vesting described below, stock options which have no value absent stock price appreciation and encourage stockholder value creation over a long-term (10 year) time horizon, and RSUs, which vest based on the passage of time and fluctuate in value based on changes in our stock price. PSUs, stock options and RSUs generally vest over a three year period of employment.

We aim to provide long-term awards such that together with cash compensation, target total direct compensation is within a competitive range of the market median. Compensation is intended to vary based on company and individual performance outcomes. The Committee bases individual award levels on comparative market data for the executive’s position, award levels of comparably-situated executives, and an assessment of individual potential and performance. In making awards to any individual, the Committee does not consider his or her gains made, or failure to achieve gains, on prior restricted stock, stock option or performance stock unit awards.

2015 LTIP. The 2015 LTIP was designed to support our multi-year strategic plan and reward each of the NEOs for their contribution to the achievement of plan goals in 2015. NEO equity grants were 60% PSUs, 20% stock options and 20% RSUs for our non-CEO NEOs; the mix for our CEO was: 60% PSUs, 25% stock options and 15% RSUs. Our program balances mid-term (PSUs) and long-term (stock options) goals and stockholder valuation creation, with key employee motivation and retention. The RSUs and stock options in the 2015 LTIP vest equally over three years on the anniversary of the grant date. The PSUs also vest, assuming performance criteria is met, in equal annual installments over three years on the anniversary of the grant date.

The following table illustrates performance objectives and final payout rate of 2015 LTIP PSUs as converted to shares of Company common stock for NEOs:

Company Goals	Weight	Threshold	Target Performance Goal	Maximum	Actual Result (1)	2015 Earned Payout Factor(2)
Adjusted Net Income EPS(3)	40%	$4.43	$5.19	$5.92	$4.80	74.1%
PPG Adjusted Revenue(3)	60%	$845,489,000	$892,460,000	$937,082,000	$866,046,646	71.9%
PSU Conversion based on 2015 performance						72.8%

⁽¹⁾ Result as determined under the 2015 WEX Inc. Long-Term Incentive Program.

⁽²⁾ Payout factor represents payout level based on 50 percent payout for threshold performance, 100 percent payout for target performance, 200 percent payout for maximum performance, interpolation on a straight-line basis between these levels of performance based on the actual result.

⁽³⁾ The reconciliation of the results and performance factors are contained in Appendix A.

Peer Group

We have created a compensation structure that focuses on the median of our selected peer companies, but also allows total target compensation to vary to reflect considerations, such as company performance, individual experience, job responsibilities and other individual performance factors.

A key element of this process is selecting a relevant peer group against which we compare our elements of pay. The Committee reviews and determines the composition of our peer group, considering input from its independent compensation consultant. For 2015, our peer group consisted of the 11 companies shown below, whose aggregate profile was comparable to WEX in terms of size, industry and competition for executive talent.

2015 Peer Group
Cardtronics Inc.	Heartland Payment Systems, Inc.
CSG Systems International Inc.	Jack Henry & Associates Inc.
Euronet Worldwide Inc	Total System Services, Inc.
EVERTEC, Inc	Vantiv, Inc.
FleetCor technologies, Inc.	VeriFone Systems, Inc.
Global Payments Inc.

	WEX ($millions)	Peer Median ($millions)
Market Capitalization (at 12/31/2015)	$3,416	$3,825
2015 EBITDA Margin	35%	23%
2015 Revenue	$855	$1,772
3-Year Revenue Growth	37%	33%

For certain NEOs, data relating to the peer group is supplemented with functional data from two general executive compensation surveys conducted by national compensation consulting firms: Mercer Executive Survey and Radford Global Technology Survey - US. With respect to these surveys, the identity of the individual companies comprising the survey data is not considered by the Committee in its evaluation process. Peer group data and other information provided to the Committee were considered in setting target compensation levels for our NEOs. For purposes of defining the market for each individual role, the Committee used the peer group data for the CEO and CFO; for the other NEOs, the Committee supplemented peer group data with the survey data described above.

During 2015, on average, target total direct compensation of our NEOs was positioned between market 25th percentile and median of the market. Adjustments are typically made when we believe that there is a market-based gap and/or as warranted by individual performance.

28

Strong Say on Pay Support and Stockholder Engagement

We have adopted a policy of conducting an annual advisory vote on executive compensation. While this vote is not binding on us, our Board of Directors and the Committee value the opinions of our stockholders. At our 2015 Annual Stockholders Meeting, approximately 99.7% of votes cast supported WEX’s executive compensation program. We received a similar level of stockholder support in 2014 and in 2013. Management and the Compensation Committee reviewed our stockholders’ affirmative 2015 Say-on-Pay vote, and believe it to be a strong indication of support for WEX’s executive compensation program and practices.

In addition to our annual advisory vote on executive compensation, we are committed to ongoing engagement with our stockholders. These engagement efforts take place throughout the year through meetings, telephone calls and correspondence involving our senior management and representatives of our stockholders.

29

Changes for 2016

Though encouraged by strong stockholder support for our compensation program, exhibited through our Say on Pay vote results (99.7% support in 2015), we refined our executive compensation program for 2016. The changes - outlined below - are intended to support our business strategy, as well as to enhance alignment with longer-term value creation for stockholders, taking into account views of various internal and external stakeholders.

Changes We've Made For 2016	Rationale
Short Term Incentive Plan ("STIP")
w Changed common financial performance metrics and weightings to 50% Company PPG Revenue and 50% Company Operating Income	w In determining new common corporate financial goals, the Committee considered the board-approved strategic plan, management input, investor voting policies and stockholder feedback w Operating Income goals evaluate annual performance excluding the impact of tax (among other items), which is taken into account - on a multi-year basis - in the PSU program
Long Term Incentive Plan ("LTIP")
w For 2016 long-term incentive awards, extended PSU performance period from 1 year to 2 years	w Changes support a longer-term focus on company goals and planning w Eliminates overlap in performance metrics with short-term incentive program, while continuing to recognize the importance of top line growth for our business w Recognizes the importance of revenue diversification for our business, given the impact volatile fuel prices can currently have on our business results
w Modified PSU vesting from 33% each year, assuming performance thresholds are attained, to 50% after year 2 and 50% after year 3, assuming performance thresholds are attained
w Replaced PPG Revenue metric with Non-Fuel Price Sensitive Revenue metric
w Changed metric weightings in the PSU program to 40% Non-Fuel Price Sensitive Revenue and 60% ANI EPS

Other Compensation Program and Governance Features.

Compensation Risk Analysis. In 2016, the Committee was presented and reviewed the conclusions of a risk assessment of our compensation policies and practices covering employee groups, which is conducted annually by representatives from Human Resources working with the Committee’s independent consultant. The Committee evaluated the levels of risk-taking that potentially could be encouraged by our compensation arrangements, taking into account the arrangements’ risk-mitigation features, to determine whether they are appropriate in the context of our strategic plan and annual budget, our overall compensation arrangements, our compensation objectives and the Company’s overall risk profile. We have concluded that WEX has an executive compensation program that balances competitive compensation with performance incentives and does not use compensation policies or practices - across employee groups - that could create risks that are reasonably likely to have a material adverse effect on the Company. Select identified risk-mitigation features with respect to our NEOs include the following:

• A competitive base salary, which provides executives with ongoing income;

• Rigorous budget and goal setting processes that involve multiple levels of review;

• Independent oversight of incentive program design and payouts;

• Use of common performance metrics;

• Different performance-measurement and time-based vesting requirements between our short-term and long-term incentive programs;

• Robust stock ownership guidelines and anti-hedging policy; and

• Committee approval for all Section 16 Executive Officer compensation.

Tax Deductibility of Compensation. Section 162(m) generally limits the deductibility of compensation paid to our NEOs (excluding the CFO) to $1 million during any fiscal year unless such compensation is "performance-based." In general, we seek to structure incentive compensation arrangements in a manner that complies with these tax rules. The Committee reserves the right to pay compensation that may exceed the limits on tax deductibility or not satisfy the performance-based award exception, such as time-based restricted stock units, if it determines doing so is in our and our stockholders’ best interests.

Under the 2015 Section 162(m) Performance Incentive Plan ("PIP"), our NEOs’ 2015 annual incentive awards were initially funded under a performance formula of 6% of WEX’s Adjusted Net Income, with a maximum defined for each participant. These amounts were subject to the Committee’s exercise of negative discretion, as described in the short-term incentive plan section above.

Accounting Implications. In designing our compensation and benefit programs, the Committee reviews and considers the accounting implications of its decisions, including the accounting treatment of amounts awarded or paid to our executives.

Executive Stock Ownership Guidelines. In order to further align the interests of management and stockholders, we maintain stock ownership guidelines for our executives. The guidelines require that executives attain a specified level of ownership of shares of the company’s common stock equal in value to a multiple of base salary within the later of five years of the executive’s appointment to their role or the applicability of these guidelines:

2015 Guidelines
Role	Multiple of Base Salary
Chief Executive Officer	5.0x
Executive Vice Presidents and Senior Vice Presidents	3.0x
Vice Presidents	1.0x

Until the minimum level of ownership is achieved, executives must retain, net after tax, 50% of any earned PSUs upon vesting, any RSUs upon vesting, and/or any stock options upon exercise.

The Compensation Committee reviews the ownership level for covered executives each year. As of the 2015 measurement of ownership, all NEOs were in compliance with the guidelines. "Equity," for the purposes of executive ownership guidelines, includes shares of our common stock owned directly or indirectly and ownership interests in the WEX

31

Common Stock Fund held in the Company's 401(k) Plan, as well as 50% percent of unvested time-based RSU awards. Stock options and unearned, unvested PSUs are not counted.

Anti-Hedging Policy. As part of our insider trading policy, our directors and executive officers are prohibited from engaging in any hedging or monetization transactions of our common stock, including through the use of financial instruments such as short sales "against the box" and purchases or sales of puts, calls, or other "derivative securities" involving the Company’s stock.

Compensation Recovery. Under the Sarbanes-Oxley Act, in the event of misconduct that results in a financial restatement that would have reduced previously paid incentive compensation, we can recoup the amount of any improper payments from our Chief Executive Officer and Chief Financial Officer. In addition, we intend to implement a clawback policy in accordance with the requirements of the Dodd-Frank Act and the regulations that will be issued under that Act. We have elected to defer adoption of a clawback policy until the SEC issues guidance as to the required elements of such a policy to ensure that we are able to implement a single fully compliant policy at one time, rather than implementing a policy that may require significant modifications after the SEC regulations are issued.

Benefits and Perquisites. We provide competitive benefits to attract and retain high performing associates at all levels. This includes a health and welfare benefits package and a 401(k) plan.

Nonqualified Deferred Compensation. The Company administers an Executive Deferred Compensation Plan, or EDCP, that provides each of the executive officers with the opportunity to defer up to 80 percent of base salary and/or up to 98 percent of short-term incentive compensation. The Company provides a match of up to 6 percent of the participant’s short-term incentive compensation deferred into the EDCP. Investment income on contributions and Company match is accrued for participants to reflect performance of investment funds identified by each participant during their annual election period. The investment funds and their performance used to calculate earnings in the EDCP generally mirror those used in the 401(k) Plan.

Each of the NEOs serving in his or her role at the time of election, with the exception of Mr. Janosick, who was eligible to participate chose to defer a portion of his or her 2015 bonus into the EDCP in 2016.

Prior to our initial public offering, we offered the WEX Inc. Supplemental Investment and Savings Plan, or SERP, which allowed participants to defer compensation. The SERP was frozen to new contributions on December 31, 2004. Ms. Smith has a balance in this plan, which continues to earn investment returns based on the funds she selects from an available menu. We believe these investment returns are market competitive for the type of funds offered; there is no preferential interest earned in either the EDCP or SERP accounts. No other executive officers participated in the SERP when it was an active plan.

The Company provides employment agreements, severance benefits and change of control benefits to attract and retain key executive officers. In the event, or threat, of a change of control transaction, these agreements reduce uncertainty and provide compensation for the significant levels of executive engagement and support required during an ownership transition that results in the termination of their employment. These agreements represent competitive severance and change of control benefits based upon the review by the Compensation Committee.

The Compensation Committee reviews these agreements annually to assess whether the total value to an executive remains at the level needed to attract and retain executives without being considered excessive in the opinion of the Compensation Committee.

The following provisions are in effect as of December 31, 2015:

		Ms. Smith	Mr. Hogan	Ms. Rapkin	Mr. Elder	Mr. Janosick
		Basic Severance Benefit
Severance Payment		1x (base salary plus target bonus)	1x (base salary)		0.5x (base salary)
Accelerated Vesting of Equity		1 year	None
Health Benefit Continuation		1 year	None
		Change in Control (CiC)(1) Severance Benefit Double Trigger: (requires CiC and loss of comparable position)
Severance Payment		2x (base salary plus target bonus)				0.5x (base salary)
Accelerated Vesting of Equity		100 percent				None
Health Benefit Continuation		2 years				None
		Other Agreements
Non-Compete(2)		2 years for without cause termination and constructive discharge with CiC; 1 year otherwise			2 years for CiC; 1 year for other scenarios	1 year
Non-Solicitation(3)
Non-Disparagement(4)
Non-Disclosure(5)		Indefinitely
(1)	"Change in control" means, in summary: (i) an acquisition of 50 percent or more of either the then-outstanding shares of common stock or the combined voting power of the then-outstanding voting securities excluding certain specified acquisitions; (ii) a change in the composition of the Board such that the individuals who constitute the Board at that point in time cease to constitute a majority of the Board; (iii) consummation of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of the assets of the Company or the acquisition of shares or assets of another Company excluding certain specified transactions; or (iv) the approval by the stockholders of the Company of a complete liquidation or dissolution of the Company.
(2)	Each of the executive officers has agreed to provisions which restrict the executive from performing any acts which advance the interests of any existing or prospective competitors of WEX during the period specified above.
(3)	Each of the executive officers has agreed to provisions which restrict the executive from soliciting customers or employees to terminate their relationship with the Company.
(4)	Each of the executive officers has agreed to provisions which restrict them from making any statements or performing any acts intended or reasonably calculated to advance the interest of any existing or prospective competitor or in any way to injure the interests of or disparage the Company.
(5)	Each of the executive officers has agreed to provisions which restrict the executive from disclosing confidential information as defined in the agreement.

(1)	For purposes of these calculations, the stock price used to calculate potential payments was the closing price on December 31, 2015, being $88.40. The officers identified above hold employee stock options that feature an exercise price of $103.75 and therefore have no present value.
(2)	As used in this table, Non-Qualified Plan Payout includes the participants' balances in their EDCP and SERP accounts.
(3)	Mr. Elder is covered by the WEX Severance Plan for Officers which provides for 26 weeks of base pay for Executive Vice Presidents and Senior Vice Presidents who have been employed with the Company for a minimum of six months upon any termination without cause. On April 13, 2012, Mr. Elder executed a Change in Control Agreement pursuant to which, following a without cause termination or a constructive discharge (both as defined in the agreement), within 90 days before a change in control (as defined in the agreement) and ending 365 days after a change in control (as defined in the agreement), he will receive (i) a cash payment equal to the sum of his then current base salary plus his then current target incentive compensation award, multiplied by 200%, payable, at the company's option, in either one lump sum, equal installments not less frequently than once per month over a twelve month period, or a combination of lump sum and equal installments not less frequently than once per month over a twelve month period, and (ii) any and all base salary and incentive compensation awards earned but unpaid through the date of such termination and any unreimbursed business expenses. In addition, upon such termination, those outstanding and unvested stock options and unvested RSUs held by Mr. Elder as of the date of termination will immediately become vested. In addition, the Company shall pay to Mr. Elder in a lump sum an amount equal to the present value of the Company's share of the cost of medical and dental insurance premiums for a 24 month period.
(4)	Mr. Janosick is covered by the WEX Severance Plan for Officers which provides for 26 weeks of base pay for Executive Vice Presidents and Senior Vice Presidents who have been employed with the Company for a minimum of six months upon any termination without cause.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Based solely on a review of the reports and written representations submitted to us, we believe that during 2015 all filings with the SEC by our officers, directors and 10 percent stockholders timely complied with requirements for reporting ownership and changes in ownership of our common stock under Section 16(a) of the Securities Exchange Act of 1934.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Our Board has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which WEX is a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or 5 percent stockholders (or their immediate family members), each of whom we refer to as a "related person," has a direct or indirect material interest.

If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a "related person transaction," the related person must report the proposed related person transaction to our General Counsel. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by our Board's Audit Committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the Committee will review, and, in its discretion, may ratify the related person transaction. The policy also permits the chair of the Audit Committee to review and, if deemed appropriate, approve proposed related person transactions that arise between meetings, subject to ratification by the Audit Committee at its next meeting. Any related person transactions that are ongoing in nature are reviewed annually.

A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the Audit Committee after full disclosure of the related person's interest in the transaction. The Audit Committee will review and consider such information regarding the related person transaction as it deems appropriate under the circumstances.

The Audit Committee may approve or ratify the transaction only if the Committee determines that, under all of the circumstances, the transaction is not inconsistent with the Company's best interests. The Committee may impose any conditions on the related person transaction that it deems appropriate.

In addition to the transactions that are excluded by the instructions to the SEC's related person transaction disclosure rule, the Board has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:

• interests arising solely from the related person's position as an executive officer of another entity (whether or not the person is also a director of such entity), that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10 percent equity interest in such entity, (b) the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction, (c) the amount involved in the transaction equals less than the greater of $750,000 or 1 percent of the annual consolidated gross revenues of the other entity that is a party to the transaction, and (d) the amount involved in the transaction equals less than 2 percent of the Company's annual consolidated gross revenues; and

• a transaction that is specifically contemplated by provisions of the Company's charter or By-Laws.

45

There were no relationships or related person transactions in 2015 which required review under the policy.

The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in its charter.

ITEM 3. RATIFICATION OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2016

The Audit Committee of the Board has selected Deloitte & Touche LLP, or "D&T," as the independent registered public accounting firm for the Company’s fiscal year 2016. Stockholder ratification of the appointment is not required under the laws of the State of Delaware, but the Audit Committee has decided to request that the stockholders ratify the appointment. A representative of D&T will be present at the meeting to answer appropriate questions from stockholders and will have the opportunity to make a statement on behalf of the firm, if he or she so desires.

If this proposal is not approved by our stockholders at the 2016 annual meeting, the Audit Committee will reconsider its selection of D&T. Even if the selection is ratified, the Audit Committee may, in its discretion, select a different independent registered public accounting firm at any point during the year if it determines that making a change would be in the best interests of the Company and our stockholders.

We recommend a vote FOR the ratification of Deloitte & Touche LLP as our independent registered public accounting firm.

AUDIT COMMITTEE REPORT

The Board of Directors appointed us as an audit committee to monitor the integrity of WEX's consolidated financial statements, its system of internal controls and the independence and performance of its internal audit department and independent registered public accounting firm. As an audit committee, we select the independent registered public accounting firm.

We are governed by a written charter adopted by the Board, which is available through the investor's page of the Company’s website at www.wexinc.com.

Our committee consisted of four non-employee directors at the time that the actions of the committee described in this report were undertaken. Each member of the audit committee is "independent" within the meaning of the New York Stock Exchange rules and Rule 10A-3 under the Securities Exchange Act of 1934. WEX's management is responsible for the financial reporting process, including the system of internal controls, and for the preparation of consolidated financial statements in accordance with generally accepted accounting principles. WEX's independent registered public accounting firm is responsible for auditing those financial statements. Our responsibility is to monitor and review these processes. However, we are not professionally engaged in the practice of accounting or auditing. We have relied, without independent verification, on the information provided to us and on the representations made by WEX's management and independent registered public accounting firm.

In fulfilling our oversight responsibilities, we discussed with representatives of D&T, the Company's independent registered public accounting firm for fiscal year 2015, the overall scope and plans for their audit of the consolidated financial statements for fiscal year 2015. We met with them, with and without WEX management present, to discuss the results of their examinations, their evaluations of the Company’s internal control over financial reporting and the overall quality of WEX's financial reporting. We reviewed and discussed the audited consolidated financial statements for fiscal year 2015 with management and the independent registered public accounting firm.

We also reviewed the report of management contained in the Annual Report on Form 10-K for the fiscal year ended December 31, 2015, filed with the SEC, as well as the Report of Independent Registered Public Accounting Firm included in the annual report on Form 10-K related to their audit of (i) the consolidated financial statements and (ii) the effectiveness of internal control over financial reporting. We continue to oversee the Company’s efforts related to its internal control over financial reporting and management’s preparations for the evaluation in fiscal year 2016.

We discussed with the independent registered public accounting firm the matters required to be discussed by Auditing Standard No. 16, Communication with Audit Committees, as amended, as adopted by the Public Company Accounting Oversight Board, including a discussion of WEX’s accounting principles, the application of those principles, and the other matters required to be discussed with audit committees under generally accepted auditing standards.

In addition, we received from the independent registered public accounting firm the letter and the written disclosures required by the applicable requirements of the Public Company Accounting Oversight Board, and discussed the disclosures with our independent registered accounting firm, as well as other matters relevant to their independence from management and WEX. In evaluating the independence of our independent registered public accountant, we considered whether the services they provided beyond their audit and review of the consolidated financial statements were compatible with maintaining their independence. We also considered the amount of fees they received for audit and non-audit services.

Based on our review and these meetings, discussions and reports, we recommended to the Board of Directors that the audited consolidated financial statements for fiscal year 2015 be included in the Annual Report on Form 10-K.

INDEPENDENT REGISTERED PUBLIC ACCOUNTANT

AUDITOR SELECTION AND FEES

Auditor Selection

The Audit Committee has selected D&T as the Company’s independent registered public accountant for the 2016 fiscal year. D&T has served as the Company’s independent registered public accountant since our initial public offering.

Audit Fees

The following is a description of the fees billed to the Company by D&T for the years ended December 31, 2015 and 2014:

	December 31,
	2015		2014
Audit Fees(1)	$	3,388,017	$	2,699,830
Audit-Related Fees(2)	295,518		269,591
Tax Fees(3)	55,000		834,610
All Other Fees (4)	25,000		300,000
Total	$	3,763,535	$	4,104,031

(1)	These are the aggregate fees for professional services by D&T in connection with their audits of the annual financial statements, included in the annual report on Form 10-K, reviews of the financial statements included in quarterly reports on Forms 10-Q and audits of our internal control over financial reporting, as well as fees associated with the statutory audits of certain of our foreign entities.
(2)	These are the aggregate fees for professional services by D&T in connection with the audit of the WEX Inc. Employee Savings Plan and SSAE 16 Report.
(3)	These are the aggregate fees for professional services by D&T in connection with a domestic tax study.
(4)	These are fees for corporate strategic consulting services for certain lines of business.

Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy regarding pre-approval of audit and non-audit services performed by D&T. According to the policy, the Audit Committee shall pre-approve all audit services to be provided to the Company, whether provided by the principal independent registered public accountant or other firms, and all other permitted services (review, attest and non-audit) to be provided to the Company by the independent registered public accountant; provided, however, that de minimis permitted non-audit services may instead be approved in accordance with applicable SEC rules. The independent registered public accountant is not authorized to provide any prohibited non-audit services (as defined in Rule 2-01(c)(4) of Regulation S-X). The Chair of the Audit Committee has the authority to pre-approve any permitted services on behalf of the Audit Committee and shall notify the full committee of such approval at its next meeting.

Since our initial public offering on February 16, 2005, the Audit Committee has pre-approved all of the services performed by D&T.

49

OTHER BUSINESS

We know of no other business to be considered at the meeting, and the deadline for stockholders to submit proposals or nominations has passed. However, if:

• other matters are properly presented at the meeting, or at any adjournment or postponement of the meeting, and

• you have properly submitted your proxy,

then, Melissa D. Smith or Roberto R. Simon will vote your shares on those matters according to her or his best judgment.

50

INFORMATION ABOUT VOTING PROCEDURES

How is my vote counted?

You may vote "for" or "against" or "abstain" from voting on each of the proposals scheduled to be voted on at the Annual Meeting. If you abstain from voting on the proposal regarding the nomination of directors, it will not count as a vote "for" or "against" the proposal. If you abstain from voting on the other proposals, it will have the same effect as a vote "against" the proposal.

If you provide your voting instructions on your proxy, your shares will be voted:

• as you instruct, and

• according to the best judgment of the persons named in the proxy if a proposal comes up for a vote at the meeting that is not on the proxy.

If you do not indicate a specific choice on the proxy you sign and submit, your shares will be voted:

• for the three named nominees for director,

• for the approval of the company’s executive compensation,

• for the ratification of Deloitte & Touche LLP as the auditors, and

• according to the best judgment of the persons named in the proxy if a proposal comes up for a vote at the meeting that is not on the proxy.

How many votes are required for the election of directors?

Under our By-Laws, a nominee will be elected to the Board of Directors if the votes cast "for" the nominee's election exceed the votes cast "against" the nominee's election, with abstentions and "broker non-votes" not counting as votes "for" or "against." If an uncontested incumbent director nominee receives a majority of votes "against" his election, the director must tender a resignation from the Board of Directors. The Board of Directors will then decide whether to accept the resignation within 90 days following certification of the stockholder vote (based on the recommendation of a committee of independent directors). We will publicly disclose the Board of directors' decision and its reasoning with regard to the offered resignation.

How many votes are needed to approve the advisory vote on executive compensation and to ratify the selection of the independent registered public accounting firm?

The affirmative vote of the holders of a majority of the shares present at the meeting in person, or by proxy, and entitled to vote is required for the approval of the advisory vote on executive compensation and approval of the ratification of the selection of the independent registered public accounting firm. An abstention will be included in the denominator for purposes of determining the number of affirmative votes required for approval. A broker non-vote will be treated as not being entitled to vote on the proposal and will not be counted for purposes of determining whether the proposal has been approved.

Who can attend the meeting?

All stockholders as of the record date, or their duly appointed proxies, may attend the meeting. A government-issued photo identification such as a driver's license, state-issued ID card or passport, will be required. Please note that if you are a beneficial owner, you will also need to bring a copy of a brokerage statement reflecting your stock ownership in the Company as of the record date to be allowed into the meeting. You may obtain directions to the location of our Annual Meeting by writing, emailing or calling our Investor Relations department at, email: investors@wexinc.com, or telephone: (866) 230-1633.

What is the difference between a "stockholder of record" and a "beneficial owner"?

These terms describe the manner in which your shares are held. If your shares are registered directly in your name through American Stock Transfer & Trust Company, LLC, our transfer agent, you are a "stockholder of record" or registered stockholder. If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in "street name." 

What is a Broker Non-Vote?

A broker is entitled to vote shares held for a stockholder on "discretionary" matters without instructions from the beneficial owner of those shares. However, if a beneficial owner does not provide timely instructions, the broker does not have the authority to vote on any "non-discretionary" proposals at the Annual Meeting and a "broker non-vote" would occur. The

51

only matter at the 2016 Annual Meeting that is "discretionary" is the ratification of our independent registered public accounting firm. The other matters are "non-discretionary." Please instruct your broker how to vote your shares using the voting instruction form provided by your broker or following any instructions provided by your broker regarding your ability to vote by telephone or through the Internet.

What if I do not vote?

The effect of not voting will depend on how your share ownership is registered. If you own shares as a registered holder and you do not vote, then your unvoted shares will not be represented at the meeting and will not count toward the quorum requirement. If a quorum is obtained, then your unvoted shares will not affect whether a proposal is approved or rejected.

If you are a stockholder whose shares are not registered in your name and you do not vote, then your bank, broker or other nominee, who is the holder of record, may still represent your shares at the meeting for purposes of obtaining a quorum. In the absence of your voting instructions, under stock exchange rules, if applicable, your bank, broker or other nominee will be able to vote your shares in its discretion regarding the ratification of the Company's independent auditors. However, under stock exchange rules, if applicable, your bank, broker or other nominee will not be able to vote your shares in its discretion in the election of directors or the advisory vote on executive compensation. Therefore, you must vote your shares if you want them to be counted for purposes of these votes.

What if I change my mind after I submit my proxy?

If your stock is registered in your name, you may revoke your proxy and change your vote by:

• signing a proxy card with a later date and returning it before the polls close at the meeting, or

• voting at the meeting

If you hold your stock in "street name," you should follow the instructions provided by your bank, broker or other nominee.

Your attendance at the meeting alone will not automatically revoke your proxy.

What happens if a director nominee is unable to stand for election?

The Board may reduce the number of directors or select a substitute nominee. In the latter case, if you have submitted your proxy, the persons named in the proxy can vote your shares for a substitute nominee. The person you authorize to vote on your behalf cannot vote for more than three nominees.

What constitutes a quorum?

In order for business to be conducted at the meeting, a quorum must be present. A quorum consists of the holders of one-third of the shares of common stock issued and outstanding on the record date and entitled to vote.

Shares of common stock represented in person or by proxy (including shares that abstain or do not vote with respect to one or more of the matters to be voted upon) will be counted for purposes of determining whether a quorum exists. If a quorum is not present, the meeting will be adjourned until a quorum is obtained.

What is the effect of not submitting my proxy if my shares are held in the WEX Inc. Employee Savings Plan?

The trustee for the WEX Inc. Employee Savings Plan, which is often referred to as the 401(k) plan, will not vote the shares of participants who do not give specific instructions as to how those shares should be voted. As a result, your unvoted shares will not be represented at the meeting and will not count toward the quorum requirement. If a quorum is obtained, then your unvoted shares will not affect whether a proposal is approved or rejected.

What does it mean if I receive more than one proxy card?

It means that you hold your shares in multiple accounts. Please be sure to complete and submit all proxies that you received to ensure that all your shares are voted.

Where do I find voting results of the meeting?

We will announce preliminary voting results at the annual meeting. We will also publish the preliminary or, if available, the final results in a current report on Form 8-K within four business days of the end of the meeting. You may access a copy of

52

the current report on Form 8-K electronically on our website or through the SEC's website at www.sec.gov. Voting results will be tabulated and certified by our transfer agent, American Stock Transfer & Trust Company.

Who pays the cost for proxy solicitation?

The Company pays for distributing and soliciting proxies. As a part of this process, the Company reimburses brokers, nominees, fiduciaries and other custodians for reasonable fees and expenses in forwarding proxy materials to stockholders. The Company has hired Laurel Hill Advisory Group, to assist it in preparing for its annual meeting. The Company will bear the entire cost of Laurel Hill, including the payment of fees of approximately $6,000, plus reasonable expenses and other incremental charges, for its services. Although the Company does not presently intend to use Laurel Hill to solicit votes, employees of the Company or its subsidiaries may solicit proxies through mail, telephone, the Internet or other means. To the extent the Company deems it advisable, it will ask Laurel Hill to also solicit votes. Employees do not receive additional compensation for soliciting proxies. The Company will use Laurel Hill to advise it in connection with assessing the impact of the votes cast during the solicitation period.

How do I submit a stockholder proposal or director nominee for next year’s annual meeting or suggest a candidate for nomination as a director to the Corporate Governance Committee?

Any proposal that a stockholder wishes to be considered for inclusion in our proxy statement and proxy card for the 2017 annual meeting of stockholders must comply with the requirements of Rule 14a-8 under the Exchange Act and must be submitted to the Corporate Secretary, 97 Darling Avenue, South Portland, ME 04106, no later than December 24, 2016. However, in the event that the annual meeting is called for a date that is not within thirty days before or after May 13, 2017, notice by the stockholder must be received a reasonable time before we begin to print and mail our proxy materials for the 2017 annual meeting of stockholders.

If a stockholder wishes to present a proposal before the 2017 annual meeting but does not wish to have a proposal considered for inclusion in our proxy statement and proxy in accordance with Rule 14a-8 or to nominate someone for election as a director, the stockholder must give written notice to our Corporate Secretary at the address noted above. To be timely, a stockholder's notice to the Secretary must be delivered to or mailed and received no earlier than January 14, 2017, nor later than February 13, 2017. However, in the event that the annual meeting is called for a date that is not within twenty-five days before or after May 13, 2017, notice by the stockholder must be received no earlier than 120 days prior to the annual meeting and no later than the later of the 90th day prior to the annual meeting or the tenth day following the day on which notice of the date of the annual meeting is first mailed or publicly disclosed. The Company's By-Laws contain specific procedural requirements regarding a stockholder's ability to nominate a director or submit a proposal to be considered at a meeting of stockholders. The By-Laws are available on our website at www.wexinc.com, under the Corporate Governance tab.

What is "householding"?

"Householding" means that we deliver a single set of proxy materials to households with multiple stockholders, provided such stockholders give their consent and certain other conditions are met.

Some households with multiple stockholders already may have provided the Company with their consent to householding. We will provide only one set of proxy materials to each such household, unless we receive contrary instructions.

We will promptly deliver separate copies of our proxy statement and annual report, or deliver multiple copies in the future, at the request of any stockholder who is in a household that participates in the householding of the Company’s proxy materials. You may call our Investor Relations department at (866) 230-1633 or send your request to:
