These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements that are included in the Company’s Annual Report on Form 10–K for the year ended December 31, 2021, filed with the SEC on March 1, 2022. In the opinion of management, all adjustments considered necessary for a fair presentation in accordance with GAAP, which are of a normal recurring nature, have been included. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results for any future periods or the year ending December 31, 2022. We have applied the same accounting policies in preparing these quarterly financial statements as we did in preparing our 2021 annual financial statements. The Company rounds amounts in the condensed consolidated financial statements to thousands and calculates all per-share data from underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot or recalculate based on reported numbers due to rounding.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements and Supplemental Information	2. Recent Accounting Pronouncements and Supplemental Information Recent Accounting Pronouncements The following table provides a brief description of (i) recent accounting pronouncements adopted during the nine months ended September 30, 2022 and (ii) those not yet adopted, that could have a material effect on our financial statements. Standard Description Date of Adoption Method of adoptions and effect on financial statements or other significant matters Adopted During the Nine Months Ended September 30, 2022 ASU 2021-08, Business Combinations This standard requires acquirers within the scope of Subtopic 805-10, Business Combinations to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. This will generally result in an acquirer recognizing and measuring acquired contract assets and liabilities consistent with how they were recognized and measured in an acquiree’s financial statements if such financial statements were prepared in accordance with GAAP. Previously, contract assets and contract liabilities acquired were recognized at their fair value on the acquisition date. Effective for fiscal years beginning after December 15, 2022. The Company early adopted this ASU effective January 1, 2022. Adoption had no material effect on the Company’s condensed consolidated financial statements for the three and nine months ended September 30, 2022. The guidelines of this ASU will be applied prospectively for business combinations in the scope of ASC 805. Not Adopted as of September 30, 2022 ASU 2020–04, Reference Rate Reform and ASU 2021–01, Reference Rate Reform: Scope These standards provide optional guidance for a limited period of time to ease the potential financial reporting burden in accounting for (or recognizing the effects of) the discontinuation of LIBOR resulting from reference rate reform. The amendments provide optional expedients and exceptions for applying GAAP to contracts and other transactions impacted by reference rate reform. If certain criteria are met, an entity will not be required to remeasure or reassess contracts impacted by reference rate reform. Election is optional and available through December 31, 2022. The Company is currently evaluating the implications of these amendments to its current efforts for reference rate reform implementation and any impact the adoption of these ASUs would have on its financial condition and results of operations. The Company has not yet determined if it will adopt these standards, which are not expected to have a material effect on the Company’s condensed consolidated financial statements. Impairment of Goodwill Our goodwill is tested for impairment annually as of October 1, or more frequently, if events or conditions indicate the carrying amount of goodwill may not be recoverable. During the third quarter of 2022, certain triggering events were identified in our international fleet reporting units, including increasing interest rates, decreasing market valuations and inflationary pressures, leading to a decline in projected cash flows primarily in Europe, requiring us to perform an interim impairment test. We compared the carrying value of each reporting unit with assigned goodwill to its fair value, which was estimated using a combination of an income-based discounted cash flow method and a market-based guideline public company method. As a result of the financial impacts of the identified triggering events, our test concluded that the carrying value of two of our reporting units exceeded their estimated fair value, resulting in the recognition of an estimated impairment charge of $136.5 million to our Fleet Solutions segment. No triggering events were identified during the third quarter of 2022 with respect to our other reporting units.

Revenue from Contract with Customer [Abstract]
Revenues	3. Revenues In accordance with Topic 606, revenue is recognized when, or as, performance obligations are satisfied as defined by the terms of the contract, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services provided. The following tables disaggregate the Company’s consolidated revenues, substantially all of which relate to services transferred to the customer over time: Three Months Ended September 30, 2022 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Topic 606 revenues Payment processing revenue $ 188,586 $ 101,533 $ 18,913 $ 309,032 Account servicing revenue 4,718 10,748 85,944 101,410 Other revenue 21,337 66 7,511 28,914 Total Topic 606 revenues $ 214,641 $ 112,347 $ 112,368 $ 439,356 Non-Topic 606 revenues 163,453 1,628 11,692 176,773 Total revenues $ 378,094 $ 113,975 $ 124,060 $ 616,129 Three Months Ended September 30, 2021 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Topic 606 revenues Payment processing revenue $ 130,006 $ 79,815 $ 16,305 $ 226,126 Account servicing revenue 4,457 10,908 83,145 98,510 Other revenue 21,376 (636) 5,909 26,649 Total Topic 606 revenues $ 155,839 $ 90,087 $ 105,359 $ 351,285 Non-Topic 606 revenues 130,522 915 42 131,479 Total revenues $ 286,361 $ 91,002 $ 105,401 $ 482,764 Nine Months Ended September 30, 2022 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Topic 606 revenues Payment processing revenue $ 542,851 $ 255,216 $ 62,748 $ 860,815 Account servicing revenue 13,620 31,906 256,062 301,588 Other revenue 63,511 461 23,940 87,912 Total Topic 606 revenues $ 619,982 $ 287,583 $ 342,750 $ 1,250,315 Non-Topic 606 revenues 456,474 4,053 21,059 481,586 Total revenues $ 1,076,456 $ 291,636 $ 363,809 $ 1,731,901 Nine Months Ended September 30, 2021 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Topic 606 revenues Payment processing revenue $ 367,032 $ 205,345 $ 55,564 $ 627,941 Account servicing revenue 13,162 32,817 230,572 $ 276,551 Other revenue 64,044 2,820 18,763 85,627 Total Topic 606 revenues $ 444,238 $ 240,982 $ 304,899 $ 990,119 Non-Topic 606 revenues 360,348 2,424 113 362,885 Total revenues $ 804,586 $ 243,406 $ 305,012 $ 1,353,004 Contract Balances The majority of the Company’s receivables, which are excluded from the table below, are either due from cardholders who have not been deemed our customer as it relates to interchange income, or from revenues earned outside of the scope of Topic 606. The Company’s contract assets consist of upfront payments to customers under long-term contracts and are recorded upon the later of when the Company recognizes revenue for the transfer of the related goods or services or when the Company pays or promises to pay the consideration. The resulting asset is amortized against revenue as the Company satisfies its performance obligations under these arrangements. The Company’s contract liabilities consist of customer payments received before the Company has satisfied the associated performance obligations. The following table provides information about these contract balances: (In thousands) Contract balance Location on the condensed consolidated balance sheets September 30, 2022 December 31, 2021 Receivables Accounts receivable, net $ 47,917 $ 49,303 Contract assets Prepaid expenses and other current assets 19,406 8,975 Contract assets Other assets 35,005 40,718 Contract liabilities Other current liabilities 5,301 9,123 Contract liabilities Other liabilities 71,721 58,900 During the three and nine months ended September 30, 2022, the Company recognized revenue of $9.6 million and $18.7 million, respectively, related to contract liabilities existing as of December 31, 2021. Remaining Performance Obligations The Company’s unsatisfied or partially unsatisfied performance obligations as of September 30, 2022 represent the remaining minimum monthly fees on a portion of contracts across the lines of business, deferred revenue associated with stand ready payment processing obligations and contractually obligated professional services yet to be provided by the Company. The following table includes revenue expected to be recognized related to remaining performance obligations at the end of the reporting period.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	4. Acquisitions 2022 Transactions Asset Acquisition During June 2022, the Company entered into a definitive agreement to purchase a portfolio of certain assets, consisting primarily of branded commercial fleet cards from a third-party. During September 2022, the Company closed on the acquisition of these receivables, paying the seller a preliminary purchase price of $45.1 million, consisting of the face value of the account balances as of the valuation date, plus certain customary adjustments, as defined in the purchase agreement. The actual amount of accounts receivable purchased was less than the balances as of the valuation date, therefore, the Company expects to receive back within the next twelve months approximately $4.3 million in excess funds transferred at closing from the seller. We accounted for this transaction under the asset acquisition method of accounting and have allocated the total cost of the acquisition as follows: (In thousands) Cash consideration transferred to seller $ 45,083 Add: transaction costs 819 Total consideration $ 45,902 Accounts receivable, net of allowance 1, 2 $ 38,282 Receivable due back from seller 1, 2 4,282 Customer relationship intangible asset 3 3,338 $ 45,902 1 Recorded within accounts receivable in the condensed consolidated balance sheet. 2 The accounts receivable purchased have been included within operating activities in the condensed consolidated statement of cash flows. 3 The intangible asset will be amortized to expense over a three-year life. Acquisition of Remaining Interest in PO Holding On March 7, 2022, WEX Inc. and SBI entered into a share purchase agreement (the “Share Purchase Agreement”) whereby WEX Inc. purchased SBI’s remaining 4.53 percent interest in PO Holding for a purchase price of $234.0 million plus any interest accruing pursuant to the terms of the Share Purchase Agreement. The purchase price is payable in three installments of $76.7 million in each of March 2024, 2025 and 2026, with a final payment of $4.0 million also payable in March 2026. Pursuant to the Share Purchase Agreement, WEX Inc. owes SBI interest on the outstanding purchase price balance from March 2024 to March 2025 at the 12-month Secured Overnight Financing Rate (“SOFR”) (as determined on March 1, 2024) plus 1.25 percent and on the outstanding balance from March 2025 to March 2026 at the 12-month SOFR rate (as determined on March 3, 2025) plus 2.25 percent, except that no interest accrues on the $4.0 million payment due in March 2026. Using a discount rate of 3.4 percent as of the acquisition date, the Company recorded the deferred liability under this Share Purchase Agreement at its initial net present value of $216.6 million. The associated discount relative to the purchase price is being amortized as interest expense using the effective interest method over the repayment term. This transaction makes PO Holding, the direct parent of WEX Health, a wholly owned subsidiary of WEX Inc. to which the Company is solely entitled to the economic benefits. See Note 14, Redeemable Non-Controlling Interest, for more information. 2021 Transactions Asset Acquisition On April 1, 2021, WEX Inc. completed the acquisition of certain contractual rights to serve as custodian or sub-custodian to over $3 billion of HSAs from the HealthcareBank division of Bell Bank, which is owned by State Bankshares, Inc. This acquisition increased the Company’s role in its customer-directed healthcare ecosystem and aligns with its growth strategy. On the closing of the acquisition, WEX Inc. paid Bell Bank initial cash consideration of $200.0 million. The Company is required to make two additional cash payments to Bell Bank in association with this acquisition of $25.0 million in July 2023 and $12.5 million in January 2024, which are reflected within accrued expenses and other liabilities, respectively, on the condensed consolidated balance sheet as of September 30, 2022. The purchase agreement also includes potential additional consideration payable to Bell Bank annually that is calculated on a quarterly basis and is contingent, and based, upon any future increases in the Federal Funds rate. The contingent payment period began on July 1, 2021 and extends until the earlier of (i) the year ending December 31, 2030, or (ii) the date when the cumulative amount paid as contingent consideration equals $225.0 million. Given the acquisition does not meet the definition of a business, the Company accounted for this transaction as an asset acquisition, recognizing $263.4 million as a definite-lived intangible rights asset as of the acquisition date, with a weighted average life of 5.6 years. As part of this acquisition WEX Inc. allocated $11.2 million of the initial cash consideration to the repurchase of SBI’s then non-controlling interest in the U.S. Health business, reducing SBI’s ownership percentage to 4.53 percent at that time. Additionally, the Company recorded an initial deferred liability of $47.4 million equal to the present value of the deferred cash payments and a derivative liability of $27.2 million related to the additional consideration contingent upon future increases in the Federal Funds rate. See Note 13, Fair Value, for further information on the valuation of the derivative liability. Transaction costs related to the acquisition were immaterial and expensed as incurred. Acquisition of Remaining Interest in WEX Europe Services On April 13, 2021, the Company acquired the remaining interest in WEX Europe Services, which consisted of 25 percent of the issued ordinary share capital, for a purchase price of $97.0 million. As a result of the transaction, the Company now owns 100 percent of the issued ordinary share capital of WEX Europe Services, which operates as our European Fleet business. This transaction further streamlines the European Fleet business in order to create revenue synergies and increases our ability to manage the associated cost structure. Given the Company had a controlling interest in WEX Europe Services prior to the transaction, the acquisition has been accounted for as an equity transaction, resulting in a reduction of additional paid-in capital by $81.6 million, a $13.1 million elimination of the 25 percent non-controlling interest in WEX Europe Services and a reduction of accumulated other comprehensive income by $2.3 million. benefitexpress Acquisition On June 1, 2021, WEX Inc.’s subsidiary, WEX Health, completed the acquisition of Cirrus Holdings, LLC, the indirect owner of Benefit Express Services, LLC, a provider of highly configurable, cloud-based benefits administration technologies and services doing business under the name benefitexpress (the “benefitexpress Acquisition”). The transaction expanded the Company’s role in the healthcare ecosystem, bringing benefit administration, compliance services, and consumer-directed health and lifestyle spending accounts together to form a full-service benefits marketplace. Pursuant to the terms of the definitive purchase agreement, WEX Health consummated the benefitexpress Acquisition for total consideration of approximately $275 million, subject to certain working capital and other adjustments. The benefitexpress Acquisition has been accounted for using the acquisition method of accounting, which requires that assets acquired and liabilities assumed be recognized at their respective fair values on the acquisition date. The table below summarizes the allocation of such fair value of assets acquired and liabilities assumed. No measurement period adjustments were recorded during the six months ended June 30, 2022, when the purchase accounting for the acquisition became final. The following is a summary of the final allocation of the purchase price to the assets and liabilities acquired, based on the fair value at the date of acquisition: (In thousands) Cash consideration transferred, net of $15.0 million in cash and restricted cash acquired $ 259,061 Less: Accounts receivable 3,103 Customer relationships (1)(4) 84,400 Developed technologies (2)(4) 19,600 Non-compete (3)(4) 2,150 Other assets 4,387 Accrued expenses (3,498) Restricted cash payable (14,328) Other liabilities (5,177) Recorded goodwill $ 168,424 (1) Weighted average life - 9.3 years. (2) Weighted average life - 3.6 years. (3) Weighted average life - 2.5 years. (4) The weighted average life of the $106.2 million of amortizable intangible assets acquired in this business combination is 8.1 years.

Receivables [Abstract]
Accounts Receivable, Net of Allowances	5. Accounts Receivable, Net of Allowances Accounts receivable consists of amounts billed to and due from customers across a wide range of industries and other third parties. The Company often extends short-term credit to cardholders by paying the merchant for the purchase price less the fees it retains and records as revenue, then subsequently collecting the total purchase price from the cardholder. The Company also extends revolving credit to certain small fleets. The Company had approximately $182.6 million and $93.7 million in gross receivables with revolving credit balances as of September 30, 2022 and December 31, 2021, respectively. The gross receivables balance as of September 30, 2022 is inclusive of the accounts acquired as part of the asset acquisition discussed in Note 4, Acquisitions. The allowance for accounts receivable consists of reserves for both credit and fraud losses, reflecting management’s current estimate of uncollectible balances on its accounts receivable. The following tables present changes in the accounts receivable allowances by portfolio segment: Three Months Ended September 30, 2022 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Balance, beginning of period $ 89,224 $ 10,396 $ 987 $ 100,607 Net provision for credit losses 1 53,002 684 344 54,030 Charges to other accounts 2 11,296 — — 11,296 Charge-offs (65,093) (787) (164) (66,044) Recoveries of amounts previously charged-off 3,572 — 8 3,580 Currency translation (637) (572) — (1,209) Balance, end of period $ 91,364 $ 9,721 $ 1,175 $ 102,260 Three Months Ended September 30, 2021 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Balance, beginning of period $ 49,716 $ 7,519 $ 536 $ 57,771 Provision for credit losses 1 10,231 3,816 80 14,127 Charges to other accounts 2 4,046 5 — 4,051 Charge-offs (10,872) (602) (92) (11,566) Recoveries of amounts previously charged-off 1,691 163 53 1,907 Currency translation (392) (206) — (598) Balance, end of period $ 54,420 $ 10,695 $ 577 $ 65,692 Nine Months Ended September 30, 2022 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Balance, beginning of period $ 55,758 $ 9,931 $ 617 $ 66,306 Provision for credit losses 1 118,672 2,105 1,079 121,856 Charges to other accounts 2 29,913 169 (101) 29,981 Charge-offs (120,388) (1,234) (438) (122,060) Recoveries of amounts previously charged-off 8,802 — 18 8,820 Currency translation (1,393) (1,250) — (2,643) Balance, end of period $ 91,364 $ 9,721 $ 1,175 $ 102,260 Nine Months Ended September 30, 2021 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Balance, beginning of period $ 49,267 $ 9,610 $ 270 $ 59,147 Provision for credit losses 1 26,359 5,568 221 32,148 Charges to other accounts 2 12,267 5 — 12,272 Charge-offs (37,239) (4,462) (120) (41,821) Recoveries of amounts previously charged-off 4,572 176 206 4,954 Currency translation (806) (202) — (1,008) Balance, end of period $ 54,420 $ 10,695 $ 577 $ 65,692 1 The provision is comprised of estimated credit losses based on the Company’s loss-rate experience and includes adjustments required for forecasted credit loss information. The provision for credit losses reported within this table also includes the provision for fraud losses. 2 The Company earns revenue by assessing monthly finance fees on accounts with overdue balances. These fees are recognized as revenue at the time the fees are assessed. The finance fee is calculated using the greater of a minimum charge or a stated late fee rate multiplied by the outstanding balance that is subject to a late fee charge. On occasion, these fees are waived to maintain relationship goodwill. Charges to other accounts substantially represent the offset against the late fee revenue recognized when the Company establishes a reserve for such waived amounts. Concentration of Credit Risk The receivables portfolio primarily consists of a large group of homogeneous balances across a wide range of industries, which are collectively evaluated for impairment. No individual customer had a receivable balance representing 10 percent or more of the outstanding receivables balance at September 30, 2022 or December 31, 2021. The following table presents the outstanding balance of trade accounts receivable that are less than 30 and 60 days past due, shown in each case as a percentage of total trade accounts receivable: Delinquency Status September 30, 2022 December 31, 2021 Less than 30 days past due 98 % 98 % Less than 60 days past due 99 % 99 %

Earnings Per Share [Abstract]
Earnings per Share	7. Earnings per Share Basic earnings per share is computed by dividing net (loss) income attributable to shareholders by the weighted average number of shares of common stock and vested DSUs outstanding during the year. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the numerator is increased for tax effected interest expense associated with our Convertible Notes and the denominator is increased for the assumed issuance of common shares upon conversion of the Convertible Notes under the “if-converted” method, unless the effect is anti-dilutive. Additionally, diluted earnings per share includes the assumed exercise of dilutive options, the assumed issuance of unvested restricted stock units, performance-based awards for which the performance condition has been met as of the date of determination and contingently issuable shares that would be issuable if the end of the reporting period was the end of the contingency period, using the treasury stock method unless the effect is anti-dilutive. The treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the average unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase the Company’s common stock at the average market price during the period. The following table summarizes net (loss) income attributable to shareholders and reconciles basic and diluted shares outstanding used in the earnings per share computations: Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2022 2021 2022 2021 Net (loss) income attributable to shareholders $ (44,145) $ 48,318 $ 112,747 $ 11,897 Weighted average common shares outstanding – Basic 44,229 44,861 44,644 44,664 Dilutive impact of share-based compensation awards 1 — 418 328 670 Weighted average common shares outstanding – Diluted 2, 3 44,229 45,279 44,972 45,334 1 For the three months ended September 30, 2022, 0.3 million incremental shares, which would otherwise have been dilutive but for the Company’s net loss position, are excluded from the table above as the effect of including those shares would be anti-dilutive. 2 For both the three and nine months ended September 30, 2022, 0.6 million of outstanding share-based compensation awards were excluded from the computation of diluted earnings per share under the treasury stock method, as the effect of including these awards would be anti-dilutive. For the three and nine months ended September 30, 2021, 0.7 million and 0.9 million, respectively, of outstanding share-based compensation awards were excluded from the computation of diluted earnings per share under the treasury stock method, as the effect of including these awards would be anti-dilutive.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	8. Derivative Instruments The Company is exposed to certain market risks relating to its ongoing business operations. From time to time, the Company enters into derivative instrument arrangements to manage various risks including interest rate risk. Interest rate swap contracts The Company has entered into interest rate swap contracts to manage the interest rate risk associated with its outstanding variable-interest rate borrowings. Such contracts are intended to economically hedge the LIBOR component of future interest payments associated with outstanding borrowings under the Company’s Amended and Restated Credit Agreement.

Deposits	9. Deposits WEX Bank’s regulatory status enables it to raise capital to fund the Company’s working capital requirements by issuing deposits, subject to FDIC rules governing minimum financial ratios. See Note 19, Supplementary Regulatory Capital Disclosure, for further information concerning these FDIC requirements. WEX Bank accepts its deposits through certain customers as required collateral for credit that has been extended (“customer deposits”) and contractual arrangements for brokered and non-brokered certificate of deposit and money market deposit products. Additionally, WEX Bank holds HSA deposits. Customer deposits are generally non-interest bearing, certificates of deposit are issued at fixed rates, money market deposits are issued at both fixed and variable interest rates based on LIBOR or the Federal Funds rate and HSA deposits are issued at rates as defined within the consumer account agreements. The following table presents the composition of deposits, which are classified as short-term or long-term based on their contractual maturities: (In thousands) September 30, 2022 December 31, 2021 Customer deposits $ 142,700 $ 129,180 Contractual deposits with maturities within 1 year 1,2 706,971 566,427 Interest-bearing money market deposits 1 226,097 370,813 HSA deposits 3 2,070,002 960,000 Short-term contractual deposits 3,145,770 2,026,420 Contractual deposits with maturities greater than 1 year and less than 5 years 1,2 489,942 652,214 Total deposits $ 3,635,712 $ 2,678,634 Weighted average cost of HSA deposits outstanding 0.05 % 0.03 % Weighted average cost of funds on contractual deposits outstanding 1.41 % 0.48 % Weighted average cost of interest-bearing money market deposits outstanding 3.10 % 0.20 % 1 As of September 30, 2022 and December 31, 2021, all certificates of deposit and money market deposits were in denominations of $250,000 or less, corresponding to FDIC deposit insurance limits. 2 Includes certificates of deposit and certain money market deposits, which have a fixed maturity and interest rate. 3 Deposits held associated with the HSA custodial assets.

Amended and Restated Credit Agreement As part of the Amended and Restated Credit Agreement, we have senior secured tranche A term loans (the “Tranche A Term Loans”), senior secured tranche B term loans (the “Tranche B Term Loans”) and revolving credit commitments in an aggregate amount of $930.0 million under the Company’s secured revolving credit facility (the “Revolving Credit Facility”). Prior to maturity, the Tranche A Term Loans and Tranche B Term Loans require scheduled quarterly payments of $12.2 million and $3.6 million, respectively, due on the last day of each March, June, September and December. Borrowings under the Revolving Credit Facility can generally be rolled forward with interest rate resets through maturity. The Revolving Credit Facility and the Tranche A Term Loans bear interest at variable rates, at the Company’s option, plus an applicable margin determined based on the Company’s consolidated leverage ratio. The Tranche B Term Loans bear interest at variable rates, at the Company’s option, plus an applicable margin, which is fixed at 1.25 percent for base rate borrowings and 2.25 percent with respect to eurocurrency rate borrowings. As of September 30, 2022 and December 31, 2021, amounts outstanding under the Amended and Restated Credit Agreement bore a weighted average effective interest rate of 5.2 percent and 2.2 percent, respectively. The Company maintains interest rate swap contracts to manage the interest rate risk associated with its outstanding variable-interest rate borrowings. See Note 8, Derivative Instruments, for further discussion. In addition, the Company pays a quarterly commitment fee at a rate per annum ranging, as of September 30, 2022, from 0.25 percent to 0.50 percent of the daily unused portion of the Revolving Credit Facility (which was 0.30 percent and 0.40 percent at September 30, 2022 and December 31, 2021, respectively) determined based on the Company’s consolidated leverage ratio. Debt issuance costs incurred and capitalized in conjunction with the Amended and Restated Credit Agreement are being amortized into interest expense over the term of the Amended and Restated Credit Agreement using the effective interest method. Convertible Notes The Company has issued Convertible Notes in an aggregate principal amount of $310.0 million due on July 15, 2027 to an affiliate of Warburg Pincus LLC (together with its affiliate, “Warburg Pincus”). Interest on the Convertible Notes is calculated at a fixed rate of 6.5 percent per annum, payable semi-annually in arrears on January 15 and July 15 of each year. At the Company’s option, interest is either payable in cash, through accretion to the principal amount of the Convertible Notes, or a combination of cash and accretion. The Convertible Notes may be converted at the option of the holders at any time prior to maturity, or earlier redemption or repurchase of the Convertible Notes, based upon an initial conversion price of $200 per share of common stock, subject to customary adjustments as set forth in the indenture. The Company may settle conversions of Convertible Notes, at its election, in cash, shares of the Company’s common stock, or a combination thereof. Based on the closing price of the Company’s common stock as of September 30, 2022, the “if-converted” value of the Convertible Notes was less than the respective principal amount. The Company will have the right, at any time after July 1, 2023, to redeem the Convertible Notes in whole or in part if the closing price of WEX’s common stock exceeds certain thresholds, as defined within the indenture. In the event of certain fundamental change transactions, including certain change of control transactions and delisting events involving the Company, holders of the Convertible Notes will have the right to require the Company to repurchase its Convertible Notes at 105 percent of the outstanding principal amount of the Convertible Notes, plus the present value of future interest payments through the date of maturity. No such repurchase has occurred through September 30, 2022. The Company accounts for the Convertible Notes and its conversion feature as a single unit of account. The debt discount and debt issuance costs associated with the Convertible Notes are amortized to interest expense using the effective interest rate method over the seven-year contractual life of the Convertible Notes. As of both September 30, 2022 and December 31, 2021, the Convertible Notes had an effective interest rate of 7.5 percent. The Convertible Notes consist of the following: (In thousands) September 30, 2022 December 31, 2021 Principal 1 $ 310,000 $ 310,000 Less: Unamortized discounts (11,391) (12,844) Less: Unamortized issuance cost (1,834) (2,068) Net carrying amount of Convertible Notes $ 296,775 $ 295,088 1 Recorded within long-term debt, net on the condensed consolidated balance sheets, offset by the long-term portion of unamortized discounts and issuance cost.

Under the terms of these agreements, each month on a revolving basis, the Company sells certain of its Australian and European receivables to bankruptcy-remote subsidiaries consolidated by the Company, which in turn use the receivables as collateral to issue securitized debt, which is recorded in short-term debt, net on the condensed consolidated balance sheets. Amounts collected on the securitized receivables are restricted to pay the securitized debt and are not available for general corporate purposes. The Company pays interest on the outstanding balance of the securitized debt based on variable interest rates plus an applicable margin. The effective interest rate on the total outstanding securitized debt balance was 2.39 percent and 0.91 percent as of September 30, 2022 and December 31, 2021, respectively. Participation Debt From time to time, WEX Bank enters into participation agreements with third-party banks to fund customers’ balances that exceed WEX Bank’s lending limit to individual customers. Associated unsecured borrowings generally carry a variable interest rate set according to an applicable reference rate plus a margin, which ranged from 2.25 percent to 2.50 percent as of September 30, 2022. As of September 30, 2022, the Company had outstanding participation agreements for the borrowing of up to $60.0 million through May 31, 2023 and up to $40.0 million thereafter through December 31, 2023. As of September 30, 2022 and December 31, 2021, there was $29.9 million and $1.5 million borrowed against these participation agreements, respectively. Outstanding participation debt of $9.2 million and $1.5 million was recorded within short-term debt, net on the condensed consolidated balance sheets as of September 30, 2022 and December 31, 2021, respectively, with the remaining outstanding balance of $20.7 million as of September 30, 2022 recorded within long-term debt, net. As of September 30, 2022 and December 31, 2021, the average interest rate on these agreements was 5.50 percent and 2.54 percent, respectively. Borrowed Federal Funds WEX Bank borrows from uncommitted federal funds lines to supplement the financing of the Company’s accounts receivable. There were no outstanding borrowings as of September 30, 2022 and December 31, 2021. Other

Receivables [Abstract]
Off-Balance Sheet Arrangements	11. Off-Balance Sheet Arrangements WEX Europe Services and WEX Bank are each party to separate accounts receivable factoring arrangements with unrelated third-party financial institutions to sell certain of their accounts receivable balances. Each subsidiary continues to service these receivables post-transfer with no participating interest. The Company obtained true-sale opinions from independent attorneys, stating that each respective factoring agreement provides legal isolation upon bankruptcy or receivership under local law. As such, transfers under these arrangements are treated as a sale and are accounted for as a reduction in trade accounts receivable because effective control of the receivables is transferred to the buyers. Proceeds received, which are recorded net of applicable costs or negotiated discount rates, are recorded in operating activities in the condensed consolidated statements of cash flows. Losses on factoring are recorded within cost of services in the condensed consolidated statements of operations. The WEX Europe Services agreement automatically renews each January 1 unless either party gives not less than 90 days written notice of their intention to withdraw. Under this agreement, accounts receivable are sold without recourse to the extent that the customer balances are maintained at or below the credit limit established by the buyer. If customer receivable balances exceed the buyer’s credit limit, the Company maintains the risk of default. The Company sold $149.6 million and $454.2 million of accounts receivable during the three and nine months ended September 30, 2022, respectively, and $148.0 million and $411.6 million during the three and nine months ended September 30, 2021, respectively, under this arrangement. Losses on factoring were insignificant for both the three months ended September 30, 2022 and 2021. For the nine months ended September 30, 2022 and 2021, the losses on factoring were $2.3 million and $2.0 million, respectively. As of September 30, 2022 and December 31, 2021, the amounts of outstanding transferred receivables in excess of established credit limits were immaterial. Charge-backs on balances in excess of the credit limits during each of the three and nine months ended September 30, 2022 and 2021 were immaterial.

Investment Securities	12. Investment Securities The Company’s investment securities consist of (i) custodial assets deposited with, managed and invested by WEX Bank through an investment manager, which are reflected within current assets on the condensed consolidated balance sheets and (ii) securities purchased and held by WEX Bank primarily to meet the requirements of the Community Reinvestment Act, which are reflected within non-current assets on the condensed consolidated balance sheets. Investment securities are reflected at fair value and are classified as current or long-term based on management’s determination of whether such securities are available for use in current operations, regardless of the securities’ stated maturity dates. Accrued interest on investment securities is recorded within prepaid expenses and other current assets on the condensed consolidated balance sheets. As of September 30, 2022 and December 31, 2021, accrued interest on investment securities was $9.2 million and $4.2 million, respectively. The cost basis of investment securities is based on the specific identification method. Purchases, sales and maturities associated with investment securities are treated as investing activities within the condensed consolidated statements of cash flows.

Fair Value Disclosures [Abstract]
Fair Value	13. Fair Value Certain of the Company’s financial assets and liabilities are recorded at fair value. The Company determines fair value based upon quoted prices when available or through the use of alternative approaches, such as model pricing, when market quotes are not readily accessible or available. Various factors are considered in determining the fair value of the Company’s assets and liabilities, including: closing exchange or over-the-counter market price quotations; time value and volatility factors underlying options and derivatives; price activity for equivalent instruments; and the Company’s own credit standing. These valuation techniques may be based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets. • Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 – Instruments whose significant value drivers are unobservable. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents the Company’s financial instruments that are measured at fair value on a recurring basis: (In thousands) Fair Value Hierarchy September 30, 2022 December 31, 2021 Assets: Money market mutual funds 1 1 $ 17,437 $ 3,670 Investment securities, current: Debt securities: U.S. treasury notes 2 $ 361,241 $ 307,195 Corporate debt securities 2 478,373 351,843 Municipal bonds 2 45,131 31,168 Asset-backed securities 2 190,292 120,211 Mortgage-backed securities 2 304,374 138,260 Total $ 1,379,411 $ 948,677 Investment securities, non-current: Debt securities: Municipal bonds 2 $ 2,453 $ 3,108 Asset-backed securities 2 141 168 Mortgage-backed securities 2 113 123 Fixed-income mutual fund 1 24,298 27,251 Pooled investment fund measured at NAV 2 9,000 9,000 Total $ 36,005 $ 39,650 Executive deferred compensation plan trust 3 1 $ 10,503 $ 11,303 Interest rate swaps 4 2 $ 88,529 $ 15,031 Liabilities Interest rate swaps 4 2 $ — $ 19,982 Contingent consideration 5 3 $ 202,400 $ 67,300 1 The fair value is recorded in cash and cash equivalents. 2 The fair value of this security is measured at NAV as a practical expedient and has not been classified within the fair value hierarchy. The amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the condensed consolidated balance sheets. 3 The fair value is recorded as current or long-term based on the timing of the Company’s executive deferred compensation plan payment obligations. At September 30, 2022, $1.8 million and $8.7 million in fair value is recorded within prepaid expenses and other current assets and other assets, respectively. At December 31, 2021, $1.6 million an d $9.7 million in fair value is recorded within prepaid expenses and other current assets and other assets, respectively. 4 The fair value is recorded as current or long-term depending on the timing of expected discounted cash flows. At September 30, 2022, $41.8 million and $46.7 million in fair value is recorded in prepaid expenses and other current assets and other assets, respectively. At December 31, 2021, $0.1 million and $14.9 million in fair value is recorded within prepaid expenses and other current assets and other assets, respectively. At December 31, 2021, $17.6 million and $2.4 million in fair value is recorded within other current liabilities and other liabilities, respectively. 5 The fair value is recorded as current or long-term based on the timing of expected payments. At September 30, 2022, $24.2 million and $178.2 million in fair value is recorded within other current liabilities and other liabilities, respectively. At December 31, 2021, $67.3 million in fair value is recorded in other liabilities. Money Market Mutual Funds A portion of the Company’s cash and cash equivalents are invested in money market mutual funds that primarily consist of short-term government securities, which are classified as Level 1 in the fair value hierarchy because they are valued using quoted market prices for identical instruments in an active market. Debt Securities The Company determines the fair value of U.S. treasury notes using quoted market prices for similar or identical instruments in a market that is not active. For corporate debt securities, municipal bonds, and asset-backed and mortgage-backed securities, the Company generally uses quoted prices for recent trading activity of assets with similar characteristics to the debt security or bond being valued. The securities and bonds priced using such methods are generally valued using Level 2 inputs. Pooled Investment Fund (In thousands) Fair Value Unfunded Commitments Redemption Frequency Redemption Notice Period Pooled investment fund, as of September 30, 2022 $ 9,000 — Monthly 30 days The pooled investment fund is a Community Reinvestment Act-eligible investment fund, which seeks to provide bank investors with current income consistent with the returns available in adjustable-rate government guaranteed financial products by investing in Community Development loans guaranteed by the Small Business Administration. The fund maintains individual capital accounts for each investor, which reflect each individual investor’s share of the NAV of the fund. Fixed Income Mutual Fund The Company determines the fair value of its fixed income mutual fund investment using quoted market prices for identical instruments in an active market; such inputs are classified as Level 1 of the fair value hierarchy. Executive Deferred Compensation Plan Trust The investments held in the executive deferred compensation plan trust, which consist primarily of mutual funds, are classified as Level 1 in the fair value hierarchy because the fair value is determined using quoted market prices for identical instruments in active markets. Interest Rate Swaps The Company determines the fair value of its interest rate swaps based on the discounted cash flows of the difference between the projected fixed payments on the swaps and the implied floating payments using the current LIBOR curve, which are Level 2 inputs of the fair value hierarchy. Contingent Consideration As part of the asset acquisition from Bell Bank during 2021, the Company is obligated to pay additional consideration to Bell Bank contingent upon increases in the Federal Funds rate. The Company determined the fair value of this contingent consideration derivative liability based on discounted cash flows using the difference between the baseline Federal Funds rate in the purchase agreement with Bell Bank and future forecasted Federal Funds rates over the agreement term. The forecasted Federal Funds rates represent a Level 3 input within the fair value hierarchy. The resulting probability-weighted contingent consideration amounts were discounted using a discount rate, which was 3.75 percent as of September 30, 2022 and 1.45 percent as of December 31, 2021. Significant increases or decreases in the Federal Funds rates could result in material increases or decreases, respectively, to the fair value of the Company’s contingent consideration derivative liability. The Company records changes in the estimated fair value of the contingent consideration in the condensed consolidated statements of operations. Changes in the contingent consideration derivative liability are measured at fair value on a recurring basis using unobservable inputs (Level 3) and are as follows for the periods indicated: Three Months Ended Nine Months Ended (In thousands) September 30, 2022 September 30, 2021 September 30, 2022 September 30, 2021 Beginning balance $ 172,100 $ 74,900 $ 67,300 $ — Fair value recorded as a result of the acquisition — — — 27,200 Change in fair value of contingent consideration 30,300 (2,800) 135,100 44,900 Contingent consideration $ 202,400 $ 72,100 $ 202,400 $ 72,100 Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The fair value of our non-financial assets and liabilities, which include goodwill, intangible assets and property, equipment and capitalized software, are measured on a non-recurring basis. Fair value adjustments are made in the period an impairment charge is recognized. During the three and nine months ended September 30, 2022, we recognized impairment charges of $136.5 million related to our goodwill. The fair value of our reporting units are classified as Level 3 within the fair value hierarchy due to the significant unobservable inputs developed using company-specific information. For additional information, see the discussion of our impairment charges in Note 2, Recent Accounting Pronouncements and Supplemental Information, including the valuation methods and inputs used in the fair value measurements. Assets and Liabilities Measured at Carrying Value, for which Fair Value is Disclosed The fair value of the Company’s financial instruments, which are measured and reported at carrying value, is as follows for the periods indicated: (In thousands) September 30, 2022 December 31, 2021 Carrying value Fair value Carrying value Fair value Tranche A Term Loans 1 $ 905,050 $ 884,687 $ 941,742 ** Tranche B Term Loans 1 1,420,370 1,382,205 1,431,185 ** Outstanding borrowings on Revolving Credit Facility 1 88,200 ** 119,800 ** Convertible Notes 2 310,000 280,209 310,000 327,670 Contractual deposits with maturities in excess of one year 3 489,942 452,950 652,214 ** ** Fair value approximates carrying value. 1 The Company determines the fair value of borrowings on the Revolving Credit Facility and Tranche A Term Loans and Tranche B Term Loans based on market rates for the issuance of the Company’s debt, which are Level 2 inputs in the fair value hierarchy. 2 The Company determines the fair value of the Convertible Notes outstanding using our stock price and volatility, the conversion premium on the Convertible Notes and effective interest rates for similarly-rated credit issuances, all of which are Level 2 inputs in the fair value hierarchy. 3 The Company determines the fair value of its contractual deposits with maturities in excess of one year using current market interest rates for deposits of similar remaining maturities, which are Level 2 inputs in the fair value hierarchy.

Noncontrolling Interest [Abstract]
Redeemable Non-Controlling Interest	14. Redeemable Non-Controlling Interest On March 5, 2019, the Company acquired Discovery Benefits, an employee benefits administrator. The seller of Discovery Benefits, SBI, obtained a 4.9 percent equity interest in PO Holding, the then newly formed parent company of WEX Health and Discovery Benefits. As part of WEX Inc.’s purchase of the HSA contractual rights from Bell Bank on April 1, 2021, as more fully described in Note 4, Acquisitions, SBI’s ownership percentage was reduced to 4.53 percent. The original agreement provided SBI with a put right and the Company with a call right for the equity interest, which could be exercised no earlier than seven years following the date of acquisition. Upon exercise of the put or call right, the purchase price was to be calculated based on a revenue multiple of peer companies (as described in the operating agreement for PO Holding) applied to trailing twelve month revenues of the U.S. Health business. The put option made the non-controlling interest redeemable and, therefore, the non-controlling interest was classified as temporary equity outside of stockholders’ equity. Any resulting change in the value of the redeemable non-controlling interest was offset against retained earnings and impacted earnings per share. On March 7, 2022, in complete satisfaction of any rights under the PO Holding operating agreement, WEX Inc. and SBI entered into the Share Purchase Agreement whereby WEX Inc. purchased SBI’s remaining 4.53 percent interest in PO Holding. The purchase price for the shares in PO Holding was $234.0 million plus any interest accruing pursuant to the terms of the Share Purchase Agreement. The initial liability associated with the future payment of the purchase price was recorded at a net present value of $216.6 million, as more fully described in Note 4, Acquisitions. The carrying value of the redeemable non-controlling interest immediately prior to the acquisition date was $254.4 million. The $37.8 million excess carrying value as of the acquisition date was recorded within the change in value of redeemable non-controlling interest on the condensed consolidated statements of operations. This change in value of redeemable non-controlling interest was offset by $3.5 million of deferred tax expense resulting from the difference between the book and tax bases of the deferred liability payable to SBI. As a result of the acquisition, the carrying value of the redeemable non-controlling interest was reduced to zero and WEX Inc. owns 100 percent of PO Holding. The following table presents the changes in the Company’s redeemable non-controlling interest: (In thousands) 2022 2021 Balance at January 1 $ 254,106 $ 117,219 Net income attributable to redeemable non-controlling interest 268 353 Change in value of redeemable non-controlling interest (37,780) 25,044 Repurchase of non-controlling interest (216,594) — Balance at March 31 $ — $ 142,616 Net income attributable to redeemable non-controlling interest — 232 Repurchase of non-controlling interest — (11,191) Contribution from non-controlling interest — 12,457 Change in value of redeemable non-controlling interest — 43,823 Balance at June 30 $ — $ 187,937 Net income attributable to redeemable non-controlling interest — 134 Change in value of redeemable non-controlling interest — 3,416 Balance at September 30 $ — $ 191,487

Income Tax Disclosure [Abstract]
Income Taxes	15. Income Taxes The Company’s effective tax rate was (1.9) percent and 42.1 percent for the three and nine months ended September 30, 2022, respectively, and 27.2 percent and 16.6 percent for the three and nine months ended September 30, 2021, respectively. Income tax expense is based on an estimated annual effective rate, which requires the Company to make its best estimate of annual pretax income or loss. The Company’s effective tax rates for the three and nine months ended September 30, 2022 were adversely impacted primarily by a discrete tax adjustment of $12.7 million relating to the establishment of a valuation allowance recorded against a portion of deferred tax assets resulting from goodwill impairment charges. The Company’s effective tax rate for the nine months ended September 30, 2022 was also adversely impacted by a discrete tax item of $7.5 million recorded during the first quarter of 2022, primarily associated with an uncertain tax position. The effective tax rate for the nine months ended September 30, 2021 was favorably impacted primarily by significant excess tax benefits arising from stock-based compensation.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	16. Commitments and Contingencies Restructuring Activities In connection with the acquisition of eNett and Optal, during the first quarter of 2021, the Company initiated a restructuring program within the Travel and Corporate Solutions segment. The restructuring initiative consisted of employee separation costs, which the Company determined were probable and reasonably estimable. As such, the Company recorded charges incurred under this initiative of $5.4 million during the nine months ended September 30, 2021, within general and administrative expenses on the condensed consolidated statements of operations. There were no accrued charges related to this initiative as of December 31, 2021 and no further charges were incurred during the nine months ended September 30, 2022. Litigation and Regulatory Matters The Company is subject to legal proceedings and claims in the ordinary course of business. As of the date of this filing, the current estimate of a reasonably possible loss contingency from all legal proceedings is not material to the Company’s consolidated financial position, results of operations, cash flows or liquidity. Commitments Minimum Volume Commitments During June 2022, the Company and its European fuel suppliers amended existing contracts, modifying both prior period and future minimum volume commitments through 2025. As a result of these amendments, the Company reversed previously accrued penalties totaling approximately $7 million as revenue within the condensed consolidated statement of operations during the nine months ended September 30, 2022. During the three and nine months ended September 30, 2022, the Company incurred shortfall penalties of approximately $0.6 million and $1.6 million, respectively, under the amended agreements. Other Commitments Other significant commitments and contingencies as of September 30, 2022 are consistent with those discussed in Note 20, Commitments and Contingencies, to the consolidated financial statements in the Annual Report on Form 10–K for the year ended December 31, 2021.

Debt Disclosure [Abstract]
Supplementary Regulatory Capital Disclosure	19. Supplementary Regulatory Capital Disclosure The Company’s subsidiary, WEX Bank, is subject to various regulatory capital requirements administered by the FDIC and the UDFI. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, WEX Bank must meet specific capital guidelines that involve quantitative measures of WEX Bank’s assets, liabilities and certain off-balance sheet items. WEX Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could limit business activities and have a material effect on the Company’s business, results of operations and financial condition. Quantitative measures established by regulation to ensure capital adequacy require WEX Bank to maintain minimum amounts and ratios as defined in the regulations. As of September 30, 2022, the most recent FDIC exam report categorized WEX Bank as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events subsequent to that examination report that management believes have changed WEX Bank’s capital rating. The following table presents WEX Bank’s actual and regulatory minimum capital amounts and ratios: (In thousands) Actual Amount Ratio Minimum for Capital Adequacy Purposes Amount Ratio Minimum to Be Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio September 30, 2022 Total Capital to risk-weighted assets $ 605,824 13.96 % $ 347,154 8.00 % $ 433,943 10.00 % Tier 1 Capital to average assets $ 551,526 9.49 % $ 232,525 4.00 % $ 290,656 5.00 % Common equity to risk-weighted assets $ 551,526 12.71 % $ 195,274 4.50 % $ 282,063 6.50 % Tier 1 Capital to risk-weighted assets $ 551,526 12.71 % $ 260,366 6.00 % $ 347,154 8.00 % December 31, 2021 Total Capital to risk-weighted assets $ 402,406 12.63 % $ 254,984 8.00 % $ 318,731 10.00 % Tier 1 Capital to average assets $ 366,121 8.75 % $ 167,317 4.00 % $ 209,147 5.00 % Common equity to risk-weighted assets $ 366,121 11.49 % $ 143,429 4.50 % $ 207,175 6.50 % Tier 1 Capital to risk-weighted assets $ 366,121 11.49 % $ 191,238 6.00 % $ 254,984 8.00 %

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10–Q and Rule 10–01 of Regulation S–X. Accordingly, they exclude certain disclosures required by GAAP for a complete set of financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements that are included in the Company’s Annual Report on Form 10–K for the year ended December 31, 2021, filed with the SEC on March 1, 2022. In the opinion of management, all adjustments considered necessary for a fair presentation in accordance with GAAP, which are of a normal recurring nature, have been included. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results for any future periods or the year ending December 31, 2022.We have applied the same accounting policies in preparing these quarterly financial statements as we did in preparing our 2021 annual financial statements. The Company rounds amounts in the condensed consolidated financial statements to thousands and calculates all per-share data from underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot or recalculate based on reported numbers due to rounding.
Recent Accounting Pronouncements	Standard Description Date of Adoption Method of adoptions and effect on financial statements or other significant matters Adopted During the Nine Months Ended September 30, 2022 ASU 2021-08, Business Combinations This standard requires acquirers within the scope of Subtopic 805-10, Business Combinations to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. This will generally result in an acquirer recognizing and measuring acquired contract assets and liabilities consistent with how they were recognized and measured in an acquiree’s financial statements if such financial statements were prepared in accordance with GAAP. Previously, contract assets and contract liabilities acquired were recognized at their fair value on the acquisition date. Effective for fiscal years beginning after December 15, 2022. The Company early adopted this ASU effective January 1, 2022. Adoption had no material effect on the Company’s condensed consolidated financial statements for the three and nine months ended September 30, 2022. The guidelines of this ASU will be applied prospectively for business combinations in the scope of ASC 805. Not Adopted as of September 30, 2022 ASU 2020–04, Reference Rate Reform and ASU 2021–01, Reference Rate Reform: Scope These standards provide optional guidance for a limited period of time to ease the potential financial reporting burden in accounting for (or recognizing the effects of) the discontinuation of LIBOR resulting from reference rate reform. The amendments provide optional expedients and exceptions for applying GAAP to contracts and other transactions impacted by reference rate reform. If certain criteria are met, an entity will not be required to remeasure or reassess contracts impacted by reference rate reform. Election is optional and available through December 31, 2022. The Company is currently evaluating the implications of these amendments to its current efforts for reference rate reform implementation and any impact the adoption of these ASUs would have on its financial condition and results of operations. The Company has not yet determined if it will adopt these standards, which are not expected to have a material effect on the Company’s condensed consolidated financial statements.
Revenues	In accordance with Topic 606, revenue is recognized when, or as, performance obligations are satisfied as defined by the terms of the contract, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services provided.
Earnings per Share	Basic earnings per share is computed by dividing net (loss) income attributable to shareholders by the weighted average number of shares of common stock and vested DSUs outstanding during the year. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the numerator is increased for tax effected interest expense associated with our Convertible Notes and the denominator is increased for the assumed issuance of common shares upon conversion of the Convertible Notes under the “if-converted” method, unless the effect is anti-dilutive. Additionally, diluted earnings per share includes the assumed exercise of dilutive options, the assumed issuance of unvested restricted stock units, performance-based awards for which the performance condition has been met as of the date of determination and contingently issuable shares that would be issuable if the end of the reporting period was the end of the contingency period, using the treasury stock method unless the effect is anti-dilutive. The treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the average unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase the Company’s common stock at the average market price during the period.
Derivative Instruments	The Company is exposed to certain market risks relating to its ongoing business operations. From time to time, the Company enters into derivative instrument arrangements to manage various risks including interest rate risk
Fair Value of Financial Instruments	Certain of the Company’s financial assets and liabilities are recorded at fair value. The Company determines fair value based upon quoted prices when available or through the use of alternative approaches, such as model pricing, when market quotes are not readily accessible or available. Various factors are considered in determining the fair value of the Company’s assets and liabilities, including: closing exchange or over-the-counter market price quotations; time value and volatility factors underlying options and derivatives; price activity for equivalent instruments; and the Company’s own credit standing. These valuation techniques may be based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets. • Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 – Instruments whose significant value drivers are unobservable. Money Market Mutual Funds A portion of the Company’s cash and cash equivalents are invested in money market mutual funds that primarily consist of short-term government securities, which are classified as Level 1 in the fair value hierarchy because they are valued using quoted market prices for identical instruments in an active market. Debt Securities The Company determines the fair value of U.S. treasury notes using quoted market prices for similar or identical instruments in a market that is not active. For corporate debt securities, municipal bonds, and asset-backed and mortgage-backed securities, the Company generally uses quoted prices for recent trading activity of assets with similar characteristics to the debt security or bond being valued. The securities and bonds priced using such methods are generally valued using Level 2 inputs. The pooled investment fund is a Community Reinvestment Act-eligible investment fund, which seeks to provide bank investors with current income consistent with the returns available in adjustable-rate government guaranteed financial products by investing in Community Development loans guaranteed by the Small Business Administration. The fund maintains individual capital accounts for each investor, which reflect each individual investor’s share of the NAV of the fund. Fixed Income Mutual Fund The Company determines the fair value of its fixed income mutual fund investment using quoted market prices for identical instruments in an active market; such inputs are classified as Level 1 of the fair value hierarchy. Executive Deferred Compensation Plan Trust The investments held in the executive deferred compensation plan trust, which consist primarily of mutual funds, are classified as Level 1 in the fair value hierarchy because the fair value is determined using quoted market prices for identical instruments in active markets. Interest Rate Swaps The Company determines the fair value of its interest rate swaps based on the discounted cash flows of the difference between the projected fixed payments on the swaps and the implied floating payments using the current LIBOR curve, which are Level 2 inputs of the fair value hierarchy.
Segment Information	The Company determines its operating segments and reports segment information in accordance with how the Company’s CODM allocates resources and assesses performance. The Company’s CODM is its Chief Executive Officer. The operating segments are aggregated into the three reportable segments described below. • Fleet Solutions provides payment processing, transaction processing, and information management services specifically designed for the needs of fleets of all sizes from small businesses to federal and state government fleets and over-the-road carriers. • Travel and Corporate Solutions focuses on the complex payment environment of global B2B payments, enabling customers to utilize our payments solutions to integrate into their own workflows and manage their accounts payable automation and spend management functions. • Health and Employee Benefit Solutions provides a SaaS platform for consumer directed healthcare benefits and a full-service benefit enrollment solution, bringing together benefits administration, certain compliance services and consumer-directed and benefits accounts.
