On April 6, 2026, WEX Inc. launched a website in connection with its 2026 Annual Meeting of Stockholders. The website can be found at www.VotewithWEX.com. A copy of the materials can be found below.

Protect WEX’s Momentum Vote “FOR” ONLY WEX’s nine highly qualified nominees using the BLUE proxy card . The Company's Annual Meeting of Stockholders is coming up on May 5, 2026. Your support for all nine of our director nominees will ensure WEX can continue executing its clear strategy to enhance value for all shareholders. VOTE NOW WEX’s strategy is delivering

improved results. In 2025, the Company delivered record revenue. Over the past decade, WEX has compounded revenue at 11% annually, net income per diluted share by 35% annually, and adjusted net income per diluted share at 17% annually. WEX has achieved these results while continuing to scale its businesses, expand margins, and generate strong returns on investment. WEX’s Board has been executing a multi - year refreshment program. Since 2020: Six new directors have been appointed to ensure the Board maintains the right balance of skills, experience and perspectives. Eight directors have retired or are not standing for reelection at the upcoming Annual Meeting. Source: Company filings. 1 See reconciliation of GAAP net income per diluted share to non - GAAP adjusted net income per diluted share on the Legal and Other Notices page.

WEX has engaged extensively with Impactive Capital Master Fund LP (“Impactive”) and sought a constructive resolution. The Company has held dozens of meetings over multiple years and offered to appoint two of Impactive’s nominees to an expanded Board to avoid a proxy contest. Impactive has launched a disruptive proxy fight campaign. Impactive is seeking to displace three of WEX’s directors — one third of the Board — with its own candidates, including one of its principals. The Board has serious concerns regarding Impactive nominee Lauren Taylor Wolfe. The Board’s diligence identified questionable conduct on other boards, clear conflicts of interest, inattention to industry regulation and misalignment with WEX’s long - term shareholders.

We believe that replacing our incumbent directors would jeopardize the Company’s progress and momentum . IMPORTANT RESOURCES Your vote is important.
