Dear Fellow Stockholders:

On May 3, 2026, we entered into a cooperation agreement (the “Cooperation Agreement”) with Impactive Capital Master Fund LP (“Impactive”) regarding the election of directors to our board of directors (the “Board”) at our 2026 annual meeting of stockholders (including any adjournments or postponements thereof, the “2026 Annual Meeting”). Pursuant to the Cooperation Agreement, the Board of WEX (the “Company”) has set the size of the Board to eleven directors as of the 2026 Annual Meeting, and nominated Kurt Adams and Ellen Alemany (the “Independent Director Nominees”) and Lauren Taylor Wolfe (the “Impactive Designee,” and together with the Independent Director Nominees, the “New Director Nominees”) and each of Daniel Callahan, Aimee Cardwell, David Foss, James Groch, Derrick Roman, Melissa Smith, Stephen Smith and Susan Sobbott for election to the Board at the 2026 Annual Meeting (collectively, the “Revised 2026 Slate”).

Pursuant to the Cooperation Agreement, Impactive has withdrawn its notice of intent to nominate director candidates for election to the Board at the 2026 Annual Meeting and terminated its solicitation of proxies in connection with the 2026 Annual Meeting. As a result, any votes on the Impactive white proxy card will not be voted at the 2026 Annual Meeting.

Further, the Company has postponed the 2026 Annual Meeting, previously scheduled to be held on May 5, 2026, to May 14, 2026 at 8:00 a.m. Eastern Time in order to give stockholders the opportunity to review the accompanying Proxy Supplement and vote for the Revised 2026 Slate on the enclosed COMPANY WHITE proxy card.

We encourage you to review the accompanying Proxy Supplement for more updated information about the 2026 Annual Meeting.

THE BOARD UNANIMOUSLY RECOMMENDS VOTING “FOR” THE ELECTION OF THE BOARD’S ELEVEN NOMINEES UNDER THE REVISED PROPOSAL 1 AND “FOR” PROPOSALS 2 AND 3 USING THE ENCLOSED COMPANY WHITE PROXY CARD. The COMPANY WHITE proxy card differs from the blue proxy card we previously furnished in that it includes a revised list of Company nominees.

YOUR VOTE IS IMPORTANT

As the beneficial owner of those shares, you may vote your shares (i) in advance of the 2026 Annual Meeting by directing your broker, bank, or other nominee how to vote, or (ii) at the 2026 Annual Meeting. To vote in advance of the 2026 Annual Meeting, you should instruct your broker, bank, or other nominee how to vote your shares by following the voting instructions in the notice provided by your broker, bank, or other nominee. You must follow the voting instructions in that notice to ensure that your vote is counted. In most cases, you will be able to vote by mail or via the Internet; however, please refer to your voting instruction form for full details. As discussed herein, your broker, bank, or other nominee may not be able to vote your shares on any matters at the 2026 Annual Meeting unless you provide instructions on how to vote your shares.

5. How will shares be voted on the COMPANY WHITE proxy card?

The shares represented by any COMPANY WHITE proxy card that is properly completed, validly executed, and received by the Company prior to or at the 2026 Annual Meeting will be voted in accordance with the specifications made on the card, whether it is returned by mail, Internet, or telephone. If you hold shares as the stockholder of record and submit a validly executed COMPANY WHITE proxy card without giving specific voting instructions on a proposal, then your shares will be voted in accordance with the recommendations of our Board as to that proposal. Our Board unanimously recommends that stockholders vote “FOR ALL” eleven Company nominees listed in Proposal 1; “FOR” the approval of, on an advisory basis, the compensation of our Named Executive Officers in Proposal 2; “FOR” the ratification of the appointment of our independent registered public accounting firm for fiscal year 2026, in Proposal 3; and in accordance with the discretion of the named proxies on other matters brought before the 2026 Annual Meeting.

To assure that your shares are represented at the 2026 Annual Meeting, we urge you to date, sign and return the enclosed COMPANY WHITE proxy card in the postage-paid envelope provided, or vote by telephone or the Internet as instructed on the COMPANY WHITE proxy card, whether or not you plan to attend the 2026 Annual Meeting.

7. Why was the 2026 Annual Meeting postponed?

ADDITIONAL INFORMATION ABOUT THE 2026 ANNUAL MEETING

9. 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 2026 Annual Meeting and a “broker non-vote” would occur. The only matter at the 2026 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 on 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. We urge you to instruct your broker, bank, or other nominee how you wish your shares to be voted.

10.What is the vote required to approve each proposal?

		Vote Required for Approval
Proposal 1	To elect eleven directors for a term of one year	Directors will be elected by a plurality vote standard. This means that the eleven director nominees receiving the highest number of “for” votes cast by the shares entitled to vote at the 2026 Annual Meeting will be elected as directors.
Proposal 2	To approve on an advisory (non-binding) basis the compensation of our Named Executive Officers	The affirmative vote of a majority of votes cast affirmatively or negatively on the matter is required to approve this proposal.

• Submitting a later dated proxy over the Internet in accordance with the instructions on the proxy card; or

If you are the beneficial owner of shares held through a broker, bank, or other nominee, then you must follow the specific instructions, including applicable deadlines, provided to you by your broker, bank, or other nominee to change or revoke any instructions you have already provided to your broker, bank, or other nominee. If you have obtained a voter instruction form from your broker, bank, or other nominee that holds your shares giving you the right to vote the shares, you may change your vote by attending the virtual 2026 Annual Meeting and voting electronically if you attach to your ballot a legal proxy from your broker, bank, or other nominee saved as a PDF or image file.

• During the term of the Cooperation Agreement, Impactive is subject to customary voting commitment, standstill, non-disparagement and expense reimbursement provisions.

• The Cooperation Agreement shall remain in effect until the later of (i) the date that is thirty days prior to the advance notice deadline for director nominations for election to the Board at the 2027 Annual Meeting and (ii) the date that is ten days after the Impactive Designee or any Replacement Director ceases to serve as a director on the Board, unless earlier terminated by mutual written agreement.
