WEX — Feb 4, 2026 release

We are unable to reconcile our adjusted net income guidance to the comparable GAAP measure without unreasonable effort because of the difficulty in predicting the amounts to be adjusted, including, but not limited to, foreign currency exchange rates, unrealized gains and losses on financial instruments, and acquisition and divestiture related items, which may have a significant impact on our financial results. 17 • We are not expecting benefits from future M&A activity or share repurchases, and last year's tender offer will continue to benefit EPS growth through Q1 before annualizing. • Domestic fuel prices estimated at $3.09 per gallon for Q1 and $3.10 per gallon for the full year, based on NYMEX futures curve; this assumption reduced 2026 revenue and EPS guidance by approximately $47 million and $0.85 cents , respectively. • Interest rates reductions in line with the market Fed Funds projections of two rate cuts in 2026. When combined with cuts made during 2025, we expect average rates to be 1% lower than 2025. • Exchange rates are as of the end of January 2026. • Adjusted net income effective tax rate of 25.0% for 2026 (all periods). 18 The following tables include estimated revenue and ANI per share sensitivities to changes in PPG and interest rates as of the date of this supplement. As a reminder, the impacts of these macro factors can and will change based upon various factors, including the composition of our balance sheet. We target maintaining a materially neutral ANI per share impact from 100bps adjustments to interest rates and can adjust our profile through balance sheet strategies and hedging.
