Trading Arrangements, by Individual
Material Terms of Trading Arrangement			Trading Arrangements Our officers (as defined in Rule 16a-1 under the Exchange Act) and directors may from time to time enter into plans or arrangements for the purchase or sale of our Class A Common Stock that are intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act. During the three months ended September 30, 2023, the officers and directors of the Company set forth in the table below entered into trading plans during an open insider trading window. Name Title Adoption Date Expiration Date (1) Aggregate # of securities to be sold (2) Stephan Scholl Chief Executive Officer and Director 9/14/2023 6/21/2024 Up to 1,500,000 Katie J.

Each arrangement also provided or provides for automatic termination in the event of liquidation, dissolution, bankruptcy, insolvency, or death, of the adopting person. (2) The volume and timing of sales is determined, in part, based on pricing triggers outlined in the trading arrangement. (3) The Rule 10b5-1 trading arrangement provides for the sale of a percentage of shares to be received upon future vesting of certain outstanding equity awards, net of any shares withheld by us to satisfy applicable taxes. The number of shares to be withheld, and thus the exact number of shares to be sold pursuant to Ms. Rooney’s Rule 10b5-1 trading arrangement, can only be determined upon the occurrence of the future vesting events. For purposes of this disclosure, we have reported the maximum aggregate number of shares to be sold without subtracting any shares to be withheld upon future vesting events. Each of the 10b5-1 plans in the above table included a representation from the director or officer to the broker administering the plan that such individual was not in possession of any material nonpublic information regarding the Company or the securities subject to the plan. A similar representation was made to the Company in connection with the adoption of the plan under the Company’s insider trading policy. Those representations were made as of the date of adoption of the 10b5-1 plan and speak only as of that date. In making those representations, there is no assurance with respect to any material nonpublic information of which the director or officer was unaware, or with respect to any material nonpublic information acquired by the director or officer or the Company after the date of the representation. During the three months ended September 30, 2023 , other than noted above, no ne of our officers or directors adopted, terminated or modified a 10b5-1 equity trading plan, or adopted, terminated, or modified any “non-Rule 10b5-1 equity trading arrangement”.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Nature of Business	1. Basis of Presentation and Nature of Business On July 2, 2021 (the “Closing Date”), Alight Holding Company, LLC (the "Predecessor" or "Alight Holdings") completed a business combination (the "Business Combination") with a special purpose acquisition company. On the Closing Date, pursuant to the Business Combination Agreement, the special purpose acquisition company became a wholly owned subsidiary of Alight, Inc. (“Alight”, “the Company”, “we” “us” “our” or the “Successor”). As of September 30, 2023, Alight owned 93 % of the economic interest in the Predecessor, had 100 % of the voting power and controlled the management of the Predecessor. The non-voting ownership percentage held by noncontrolling interest was approximatel y 7 % as of September 30, 2023. As a result of the Business Combination, for accounting purposes, the Company is the acquirer and Alight Holdings is the acquiree and accounting predecessor. Within this Quarterly Report on Form 10-Q, there are some instances where we reference activity that relates to this Predecessor period or accounting as a result of the Business Combination. Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and should be read in conjunction with the Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the Securities and Exchange Commission (“SEC”) on March 1, 2023. In the opinion of management, all adjustments, including normal recurring adjustments, considered necessary for a fair presentation have been included. All intercompany transactions and balances have been eliminated upon consolidation. The results of operations for interim periods are not necessarily indicative of the results to be expected for future quarters or for the full fiscal year ending December 31, 2023. Segment Reporting Effective January 1, 2023, the Company's former Hosted business revenues and gross margin are reported in Other as the business is no longer core to the Company’s operations. There is no change in composition among the Employer Solutions and Professional Services segments. Additionally, the Company changed its measure of segment profit and loss that is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the Company’s segments and assessing business performance.

Accounting Policies [Abstract]
Accounting Policies and Practices	2. Accounting Policies and Practices Use of Estimates The preparation of the accompanying Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of reserves and expenses. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. Management believes its estimates to be reasonable given the current facts available. Management adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity markets, and foreign currency exchange rate movements increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be predicted with certainty, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment would, if applicable, be reflected in the financial statements in future periods. New Accounting Pronouncements There are no recently issued accounting pronouncements that are expected to have a material impact upon our Condensed Consolidated Financial Statements.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	3. Revenue from Contracts with Customers The majority of the Company’s revenue is highly recurring and is derived from contracts with customers to provide integrated, cloud-based human capital solutions that empower clients and their employees to manage their health, wealth and HR needs. The Company’s revenues are disaggregated by recurring and project revenues within each reportable segment. Recurring revenues are typically longer term in nature and more predictable on an annual basis, while project revenues consist of project work of a shorter duration. See Note 12 “Segment Reporting” for quantitative disclosures of recurring and project revenues by reportable segment. The Company’s reportable segments are Employer Solutions and Professional Services. Employer Solutions are driven by our digital, software and AI-led capabilities powered by the Alight Worklife® platform and spanning total employee wellbeing and engagement, including integrated benefits administration, healthcare navigation, financial health and employee wellbeing and payroll. Professional Services includes project-based cloud deployment and consulting offerings. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors. Revenues are recognized when control of the promised services is transferred to the customer in the amount that best reflects the consideration to which the Company expects to be entitled in exchange for those services. The majority of the Company’s revenue is recognized over time as the customer simultaneously receives and consumes the benefits of our services. We may occasionally be entitled to a fee based on achieving certain performance criteria or contract milestones. To the extent that we cannot estimate with reasonable assurance the likelihood that we will achieve the performance target, we will constrain this portion of the transaction price and recognize it when or as the uncertainty is resolved. Any taxes assessed on revenues relating to services provided to our clients are recorded on a net basis. All of the Company’s revenues are described in more detail below. Administrative Services We provide benefits, human resource and payroll administration services across all of our solutions, which are highly recurring. The Company’s contracts may inclu de administration services across one or multiple solutions and typically have three to five-year terms with mutual renewal options. These contracts typically consist of an implementation phase and an ongoing administration phase: Implementation phase – In connection with the Company’s long-term agreements, highly customized implementation efforts are often necessary to set up clients and their human resource, payroll or benefit programs on the Company’s systems and operating processes. Work performed during the implementation phase is considered a set-up activity because it does not transfer a service to the customer. Therefore, it is not a separate performance obligation. As these agreements are longer term in nature, our contracts generally provide that if the client terminates a contract, we are entitled to an additional payment for services performed through the termination date designed to recover our up-front costs of implementation. Any fees received from the customer as part of the implementation are, in effect, an advance payment for the future ongoing administration services to be provided. Ongoing administration services phase – For all solutions, the ongoing administration phase includes a variety of plan and payroll administration services and system support services. More specifically, these services include data management, calculations, reporting, fulfillment/communications, compliance services, call center support, and in our Health Solutions agreements, annual on-boarding and enrollment support. While there are a variety of activities performed across all solutions, the overall nature of the obligation is to provide integrated administration solutions to the customer. The agreement represents a stand-ready obligation to perform these activities across all solutions on an as-needed basis. The customer obtains value from each period of service, and each time increment (i.e., each month, or each benefit cycle in the case of our Health Solutions arrangements) is distinct and substantially the same. Accordingly, the ongoing administration services for each solution represents a series and each series (i.e., each month, or each benefit cycle including the enrollment period in the case of our Health Solutions arrangements) of distinct services are deemed to be a single performance obligation. In agreements that include multiple performance obligations, the transaction price related to each performance obligation is based on a relative stand-alone selling price basis. We establish stand-alone selling price using a suitable estimation method, which includes a market assessment approach using observable market prices the Company charges separately for similar solutions to similar customers or an expected cost plus margin approach. Our contracts with our clients specify the terms and conditions upon which the services are based. Fees for these services are primarily based on a contracted fee charged per participant per period (e.g., monthly or annually, as applicable). These contracts may also include fixed components, including lump-sum implementation fees. Our fees are not typically payable until the commencement of the ongoing administration phase. Once fees become payable, payment is typically due on a monthly basis as we perform under the contract, and we are entitled to be reimbursed for work performed to date in the event of termination. For Health Solutions administration services, each benefits cycle inclusive of the enrollment period represents a time increment under the series guidance and is a single performance obligation. Although ongoing fees are typically not payable until the commencement of the ongoing administrative phase, we begin transferring services to our customers approximately four months prior to payments being due as part of our annual enrollment services. Although our per-participant fees are considered variable, they are typically predictable in nature, and therefore we do not generally constrain any portion of our transaction price estimates. We use an input method based on the labor costs incurred relative to total labor costs as the measure of progress in satisfying our Health Solutions performance obligation commencing when the customer’s annual enrollment services begin. Given that the Health Solutions enrollment and administrative services are stand-ready in nature, it can be difficult to estimate the total expected efforts or hours we will incur for a particular benefits cycle. Therefore, the input measure is based on the historical effort expended, which is measured as labor cost. For all other benefits administration, human resources and payroll services where each month represents a distinct time increment under the series guidance, we allocate the transaction price to the month we are performing our services. Therefore, the amount recognized each month is the variable consideration related to that month plus any fixed monthly or annual fee, which is recognized on a straight-line basis. Revenue for these types of arrangements is therefore more consistent throughout the year. In the normal course of business, we enter into change orders or other contract modifications to add or modify services provided to the customer. We evaluate whether these modifications should be accounted for as separate contracts or a modification to an existing contract. To the extent that the modification changes a promise that forms part of the underlying series, the modification is not accounted for as a separate contract. Other Contracts In addition to the ongoing administration services, the Company also has services across all solutions that represent separate performance obligations and that are often shorter in duration, such as our cloud deployment services, cloud advisory services, participant financial advisory services, and enrollment services not bundled with ongoing administration services. Fee arrangements can be in the form of fixed-fee, time-and-materials, or fees based on assets under management. Payment is typically due on a monthly basis as we perform under the contract, and we are entitled to be reimbursed for work performed to date in the event of termination. Services may represent stand-ready obligations that meet the series provision, in which case all variable consideration is allocated to each distinct time increment. Other services are recognized over-time based on a method that faithfully depicts the transfer of value to the customer, which may be based on the value of labor hours worked or time elapsed, depending on the facts and circumstances. The majority of the fees for enrollment services not bundled with ongoing administration services may be in the form of commissions received from insurance carriers for policy placement and are variable in nature. These annual enrollment services include both employer-sponsored arrangements that place both retiree Medicare coverage and voluntary benefits and direct-to-consumer Medicare placement. Our performance obligations under these annual enrollment services are typically completed over a short period upon which a respective policy is placed or confirmed with no ongoing fulfillment obligations. For both the employer-sponsored and direct-to-consumer arrangements, we recognize the majority of the placement revenue in the fourth quarter of the calendar year, which is when most of the placement or renewal activity occurs. However, the Company may continue to receive commissions from carriers until the respective policy lapses or is canceled. The Company bases the estimates of total transaction price on supportable evidence from an analysis of past transactions, and only includes amounts that are probable of being received or not refunded. As it relates to the direct-to-consumer arrangements, because our obligation is complete upon placement of the policy, we recognize revenue at that date, which includes both compensation due to us in the first year as well as an estimate of the total renewal commissions that will be received over the lifetime of the policy. The variable consideration estimate requires significant judgement, and will vary based on product type, estimated commission rates and the expected lives of the respective policies and other factors. For both the employer-sponsored and direct-to-customer arrangements, the estimated total transaction price may differ from the ultimate amount of commissions we may collect. Consequently, the estimate of total transaction price is adjusted over time as the Company receives confirmation of cash received, or as other information becomes available. A portion of the Company's revenue is subscription-based where monthly fees are paid to the Company. The subscription-based revenue is recognized straight-line over the contract term, which is generally three years . The Company has elected to apply practical expedients to not disclose the revenue related to unsatisfied performance obligations if (1) the contract has an original duration of one year or less, or (2) the variable consideration is allocated entirely to an unsatisfied performance obligation which is recognized as a series of distinct goods and services that form a single performance obligation. Contract Costs Costs to obtain a Contract The Company capitalizes incremental costs to obtain a contract with a customer that are expected to be recovered. Assets recognized for the costs to obtain a contract, which primarily includes sales commissions paid in relation to the initial contract, are amortized over the expected life of the underlying customer relationships, which is 7 years for our payroll and cloud solutions and generally 15 years for all of our other solutions. For situations where the duration of the contract is 1 year or less, the Company has applied a practical expedient and recognized the costs of obtaining a contract as an expense when incurred. These costs are recorded in Cost of services, exclusive of depreciation and amortization in the Condensed Consolidated Statements of Comprehensive Income (Loss). Costs to fulfill a Contract The Company capitalizes costs to fulfill contracts which includes highly customized implementation efforts to set up clients and their human resource, payroll or benefit programs. Assets recognized for the costs to fulfill a contract are amortized on a systematic basis over the expected life of the underlying customer relationships, which is 7 years for our payroll and cloud solutions and generally 15 years for all of our other solutions. Amortization for all contracts costs is recorded in Cost of services, exclusive of depreciation and amortization in the Condensed Consolidated Statements of Comprehensive Income (Loss), see Note 5 “Other Financial Data”.

Acquisitions	4. Acquisitions 2022 Acquisitions In December 2022, the Company completed the acquisition of ReedGroup for a preliminary purchase price of approximately $ 87 million, net of cash acquired. This acquisition was not material to the Company’s results of operations, financial position, or cash flows. The Company accounted for the acquisition as a business combination under Accounting Standards Codification Topic 805, Business Combinations. The goodwill identified by this acquisition is primarily attributed to the synergies that are expected to be realized as well as intangible assets that do not qualify for separate recognition, such as assembled workforce. None of the goodwill is expected to be deductible for income tax purposes. The preliminary purchase price allocation was based upon a preliminary valuation, and the Company's estimates and assumptions are subject to change within the measurement period (not to exceed twelve months following the acquisition date). For the nine months ended September 30, 2023 , there were immaterial changes to the preliminary purchase price allocation. The business is now wholly owned by the Company and is included within the Employer Solutions segment.

Income Taxes	7. Income Taxes The Company’s effective tax rates for the three months ended September 30, 2023 and 2022 wer e ( 207 %) a nd 31 %, respectively. The Company’s effective tax rates for the nine months ended September 30, 2023 and 2022 we re ( 16 %) a nd 82 %, respectively. The changes in the effective tax rates were primarily driven by the Company’s forecasted ability to partially benefit from current year anticipated tax attributes for which a full federal valuation allowance was provided for in the prior period. The effective tax rates for the three and nine months ended September 30, 2023 was lower than the 21 % U.S. statutory corporate income tax rate. This difference is primarily due to lower realization of certain anticipated tax attributes in the U.S., as well as losses in certain non-U.S. jurisdictions for which tax benefits have not been recorded.

In August 2020, the Company refinanced a portion of the Term Loan by paying down $ 270 million of principal using the proceeds from the August 2020 Unsecured Senior Notes issuance, extending the maturity date on $ 1,986 million of the balance to October 31, 2026 , and adding an interest rate floor of 50 bps (the "Amended Term Loan"). As part of the consideration transferred in the Business Combination, $ 556 million of principal was repaid on the portion of the Term Loan that was not amended.

The Alight Holdings limited liability company agreement contains provisions which require that a one-to-one ratio is maintained between each class of Alight Holdings units held by Alight and its subsidiaries (including the Alight Group, Inc. and certain tax blocker entities, but excluding subsidiaries of Alight Holdings) and the number of outstanding shares of the corresponding class of Alight common stock, subject to certain exceptions (including in respect of management equity in the form of options, rights or other securities which have not been converted into or exercised for Alight common stock). In addition, the Alight Holdings limited liability company agreement permits Alight, in its capacity as the managing member of Alight Holdings, to take actions to maintain such ratio, including undertaking stock splits, combinations, recapitalizations and exercises of the exchange rights of holders of Alight Holdings units. Exchange of Class A Units During the nine months ended September 30, 2023, 26,915,655 Class A units and a corresponding number of shares of Class V Common Stock were exchanged for Class A Common Stock. As a result of the exchanges, Alight, Inc. increased its ownership in Alight Holdings and accordingly increased its equity by approximately $ 269 million , recorded in Additional paid-in capital. Pursuant to the TRA that we entered into in connection with the Business Combination, described in Note 15 "Tax Receivable Agreement," the Class A unit exchanges created additional TRA liabilities of $ 86 million, with offsets to Additional paid-in-capital. An addition al $ 20 million increase to Additional paid-in-capital was due to exchanges as a result of deferred tax assets due to our change in ownership. Secondary Offerings On March 6, 2023, the Company completed a secondary offering of 46,000,000 shares of the Company’s Class A Common Stock by certain selling stockholders at a public offering price of $ 9.00 per share. In connection with the offering, the selling stockholders granted the underwriters a 30-day option to purchase up to 6,900,000 additional shares of the Company’s Class A Common Stock, which the underwriters exercised in full. The Company did not sell any shares of Class A Common Stock in the offering and did not receive any proceeds from the offering. Alight paid the costs associated with the sale of shares by the selling stockholders, net of the underwriting discounts. On August 16, 2023, the Company completed a secondary offering of 22,500,000 shares of the Company’s Class A Common Stock by certain selling stockholders at a public offering price of $ 7.98 per share. The Company did not sell any shares of Class A Common Stock in the offering and did not receive any proceeds from the offering. The Company paid the costs associated with the sale of shares by the selling stockholders, net of the underwriting discounts. Share Repurchase Program On August 1, 2022, the Company's Board of Directors authorized a share repurchase program (the "Program"), under which the Company may repurchase up to $ 100 million of issued and outstanding shares of Class A Common Stock, par value $ 0.0001 per share, from time to time, depending on market conditions and alternate uses of capital. The Program has no expiration date and may be suspended or discontinued at any time. The Program does not obligate the Company to purchase any particular number of shares and there is no guarantee as to any number of shares being repurchased by the Company. During the three and nine months ended September 30, 2023, 3,294,008 and 4,921,468 Class A Common Stock shares, respectively, were repurchased under the Program for a total cost of $ 26 million and $ 40 million , respectively. As of September 30, 2023, there was $ 48 million remaining under the Program authorization for future share repurchases. Repurchased shares are reflected as Treasury Stock on the Consolidated Balance Sheets as a component of equity. The following table reflects the changes in our outstanding stock: Class A (2) Class B-1 Class B-2 Class V Class Z Treasury Balance at December 31, 2022 470,756,961 4,990,453 4,990,453 63,481,465 5,595,577 1,506,385 Conversion of noncontrolling interest 19,345,591 — — ( 19,345,591 ) — — Shares granted upon vesting 1,035,470 — — — ( 398,496 ) — Issuance for compensation to non-employees (1) 18,059 — — — — — Share repurchases ( 1,148,435 ) — — — — 1,148,435 Balance at March 31, 2023 490,007,646 4,990,453 4,990,453 44,135,874 5,197,081 2,654,820 Conversion of noncontrolling interest 58,766 — — ( 58,766 ) — — Shares granted upon vesting 842,570 — — — — — Issuance for compensation to non-employees (1) 19,979 — — — — — Share repurchases ( 479,025 ) — — — — 479,025 Balance at June 30, 2023 490,449,936 4,990,453 4,990,453 44,077,108 5,197,081 3,133,845 Conversion of noncontrolling interest 7,511,298 — — ( 7,511,298 ) — — Shares granted upon vesting 389,767 — — — — — Issuance for compensation to non-employees (1) 24,608 — — — — — Share repurchases ( 3,294,008 ) — — — — 3,294,008 Balance at September 30, 2023 495,081,601 4,990,453 4,990,453 36,565,810 5,197,081 6,427,853 (1) Issued to certain members of the Board of Directors in lieu of cash retainer.

Accumulated Other Comprehensive Income As of September 30, 2023, the Accumulated other comprehensive income ("AOCI") balance included unrealized gains and losses for interest rate swaps and foreign currency translation adjustments related to our foreign subsidiaries that do not have the U.S. dollar as their functional currency. The tax effect on the Company's pre-tax AOCI items is recorded in the AOCI balance. This tax is comprised of two items: (1) the tax effects related to the unrealized pre-tax items recorded in AOCI and (2) the tax effect related to certain valuation allowances that have also been recorded in AOCI. When unrealized items in AOCI are recognized, the associated tax effects on these items will also be recognized in the tax provision.

Share-Based Compensation Expens

Share-Based Compensation Expense	Sep. 30, 2023
Share-Based Payment Arrangement [Abstract]
Share-Based Compensation Expense	10. Share-Based Compensation Expense Predecessor Plans Prior to the Business Combination, share-based payments to employees include grants of restricted share units (“RSUs”) and performance based restricted share units (“PRSUs”), which consist of both Class A-1 and Class B common units in each type, are measured based on their estimated grant date fair value. The grant date fair value of the RSUs is equal to the value of the shares acquired by the Predecessor’s initial investors at the time of Alight Holding’s formation in 2017. The grant date fair values of the PRSUs are based on a Monte Carlo simulation methodology, which requires management to make certain assumptions and apply judgement. Management determined the expected volatility based on the average implied asset volatilities of comparable companies as we do not have sufficient trading history for the PRSUs. The expected term represents the period that the PRSUs are expected to be outstanding. Because of the lack of sufficient historical data necessary to calculate the expected term, we used the contractual vesting period of five years to estimate the expected term. For the Predecessor period, the key assumptions included in the Monte Carlo simulation were expected volatility of 45 %, a risk-free interest rate of 1 % and no expected dividends. The Company recognizes share-based compensation expense on a straight-line basis over the requisite service period for awards expected to ultimately vest. As a result of the change in control related to the Business Combination, the vesting of the time-based PRSU Class B units accelerated on the Closing Date. Prior to the Closing Date, the time-based PRSUs vested ratably over periods of one to five years . The remaining unvested PRSU Class B units have vesting conditions that are contingent upon the achievement of defined internal rates of return and multiples on invested capital occurrence and of certain liquidity events. The Class A-1 RSUs and PRSUs that were unvested as of the Closing Date have time-based and/or vesting conditions that are contingent upon the achievement of defined internal rates of return and multiples on invested capital occurrence and of certain liquidity events. Both the unvested Class A-1 and Class B units were replaced with unvested shares of Alight common stock as discussed below. Successor Plans Share-based payments consist of grants of RSUs and PRSUs. The Company recognizes compensation expense on a straight-line basis over the requisite service period for awards expected to ultimately vest. Predecessor Replacement Awards In connection with the Business Combination, the holders of certain unvested awards under the Predecessor plans were granted replacement awards in the Successor company. • Class B units: The unvested Class B units of Alight Holdings were granted replacement unvested shares of Class A Common Stock, unvested shares of Class B-1 common stock, and unvested shares of Class B-2 common stock of the Company that ultimately vest on the third anniversary of the Closing Date, but could vest earlier based on the achievement of certain market-based conditions. • Class A-1 units: The unvested Class A-1 units of Alight Holdings were granted replacement unvested shares of Class A Common Stock, unvested shares of Class B common stock, and unvested shares of Class B-2 common stock of the Company on an equivalent fair value basis. The service-based portion of the grant vests ratably over periods of two to five years and the remaining portion vests upon achievement of certain market-based conditions. The Class B and Class A-1 units that were replaced represent the unvested Class A, unvested Class B-1 and unvested Class B-2 common stock subject to the forfeiture re-allocation provision per the Class Z instruments discussed in Note 9 “Stockholders’ Equity”. These unvested shares are accounted for as restricted stock in accordance with Accounting Standards Codification ("ASC") 718. Successor Awards In connection with the Business Combination, the Company adopted the Alight, Inc. 2021 Omnibus Incentive Plan. Under this plan, for grants issued during the nine months ended September 30, 2023, approximately 59 % of the units are subject to time-based vesting requirements and approximately 41 % are subject to performance-based vesting requirements. The majority of the time-based RSUs vest ratably each March 10 over a three-year period with one-third vesting on each of March 10, 2024, 2025 and 2026. The PRSUs granted in 2023 vest upon achievement of the Company’s performance goal, Total Business Process as a Service ("BPaaS") Revenue and Adjusted EBITDA. The Company begins to recognize expense associated with the PRSUs when the achievement of the performance condition is deemed probable. During the nine months ended September 30, 2023, expected achievement levels did not change for any of the performance periods based on management's analysis of the corresponding performance conditions. The fair value of each RSU and PRSU is based upon the grant date market price. The aggregate grant date fair value of RSUs and PRSUs granted during the nine months ended September 30, 2023 was approximately $ 50 million and $ 34 million , respectively. Restricted Share Units and Performance Based Restricted Share Units The following tables summarizes the unit activity related to the RSUs and PRSUs during the nine months ended September 30, 2023: Weighted Weighted Average Average Grant Date Grant Date Fair Value Fair Value RSUs (1) Per Unit PRSUs (1)(2) Per Unit Balance as of December 31, 2022 7,766,161 $ 10.28 30,085,723 $ 11.38 Granted 5,635,935 8.86 3,849,868 8.84 Vested ( 2,241,874 ) 9.38 ( 1,031,264 ) 10.84 Forfeited ( 1,677,522 ) 9.60 ( 3,281,215 ) 9.76 Balance as of September 30, 2023 9,482,700 $ 9.77 29,623,112 $ 11.25 (1) These share totals include both unvested shares and restricted stock units. (2) PRSUs granted includes both new grants in the period as well as adjustments in the period to existing grants to account for the expected level of achievement of the performance-based vesting requirements. Share-based Compensation Total share-based compensation costs related to the RSUs and PRSUs are recorded in the Condensed Consolidated Statements of Comprehensive Income (Loss) as follows (in millions): Three Months Ended September 30 Nine Months Ended September 30 2023 2022 2023 2022 Cost of services, exclusive of depreciation and amortization $ 9 $ 12 $ 27 $ 29 Selling, general and administrative 26 42 83 100 Total share-based compensation expense $ 35 $ 54 $ 110 $ 129 As of September 30, 2023, total future compensation expense related to unvested RSUs was $ 57 million , which will be recognized over a remaining weighted-average amortization period of approximately 1.4 years. As of September 30, 2023, total future compensation expense related to PRSUs was $ 85 million , which will be recognized over a remaining weighted-average amortization period of approximately 1.2 years. Employee Stock Purchase Plan In December 2022, the Company began offering its employees an Employee Stock Purchase Plan (the “ESPP”). Under the ESPP, all full-time and certain part-time employees of the Company based in the U.S. and certain other countries are eligible to purchase Class A Common Stock of the Company twice per year at the end of a six-month payment period (a “Payment Period”). During each Payment Period, eligible employees who so elect may authorize payroll deductions in an amount no less than 1 % nor greater than 10 % of his or her base pay for each payroll period in the Payment Period. At the end of each Payment Period, the accumulated deductions are used to purchase shares of Class A Common Stock from the Company up to a maximum of 1,250 shares for any one employee during a Payment Period. Shares are purchased at a price equal to 85 % of the fair market value of the Company’s Class A Common Stock on the last business day of a Payment Period. For the three and nine months ended September 30, 2023, 706,366 shares had been issued under the ESPP and the amount of share-based compensation expense related to the ESPP was $ 1 million .

Earnings Per Share [Abstract]
Earnings Per Share	11. Earnings Per Share Basic earnings per share is calculated by dividing the net income (loss) attributable to Alight, Inc. by the weighted average number of shares of Class A Common Stock issued and outstanding. The computation of diluted earnings per share reflects the potential dilution that could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issuance of shares that would then share in the net income of Alight, Inc. The Company’s Class V Common Stock and Class Z Common Stock do not participate in the earnings or losses of the Company and are therefore not participating securities and have not been included in either the basic or diluted earnings per share calculations. In conjunction with the Business Combination, the Company issued Seller Earnouts contingent consideration, which is payable in the Company’s Common Stock when the related market conditions are achieved. As the related conditions to pay the consideration had not been satisfied as of September 30, 2023, the Seller Earnouts were excluded from the diluted earnings per share calculations. Basic and diluted (net loss) earnings per share are as follows (in millions, ex cept for share and per share amounts): Three Months Ended September 30 Nine Months Ended September 30 2023 2022 2023 2022 Basic and diluted (net loss) earnings per share: Numerator Net (loss) income attributable to Alight, Inc. - basic $ ( 48 ) $ ( 37 ) $ ( 183 ) $ 3 Loss impact of conversion of noncontrolling interest — — — ( 1 ) Net (loss) income attributable to Alight, Inc. - diluted $ ( 48 ) $ ( 37 ) $ ( 183 ) $ 2 Denominator Weighted-average shares outstanding - basic 493,226,324 457,904,703 486,683,943 457,535,329 Dilutive effect of the exchange of noncontrolling interest units — — — 75,800,317 Dilutive effect of RSUs — — — 770,953 Weighted-average shares outstanding - diluted 493,226,324 457,904,703 486,683,943 534,106,599 Basic (net loss) earnings per share $ ( 0.10 ) $ ( 0.08 ) $ ( 0.38 ) $ 0.01 Diluted (net loss) earnings per share $ ( 0.10 ) $ ( 0.08 ) $ ( 0.38 ) $ — For the three months ended September 30, 2023 and 2022, 36,565,810 and 75,800,317 of Alight Holdings Class A units, respectively, related to noncontrolling interests were not included in the computation of diluted shares outstanding as their impact would have been anti-dilutive. For the three months ended September 30, 2023 and 2022, 9,161,197 and 10,289,937 of unvested RSUs, respectively, were not included in the computation of diluted shares outstanding as their impact would have been anti-dilutive. For the nine months ended September 30, 2023, 36,565,810 of Alight Holdings Class A units related to noncontrolling interests were not included in the computation of diluted shares outstanding as their impact would have been anti-dilutive. For the nine months ended September 30, 2023 and 2022, 9,161,197 and 9,518,984 of unvested RSUs, respectively, were not included in the computation of diluted shares outstanding as their impact would have been anti-dilutive. In addition, for the three and nine months ended September 30, 2023 and 2022, 14,999,998 shares, respectively, related to the Seller Earnouts were excluded from the calculation of basic and diluted earnings per share. For the three and nine months ended September 30, 2023 and 2022, 28,547,275 and 33,148,917 unvested PRSUs, respectively, were excluded from the calculation of basic and diluted earnings per share. For the three and nine months ended September 30, 2023 and 2022 , the share amounts were calculated based on expected achievement levels and were excluded as the performance conditions were not met as of the end of the respective periods.

Segment Reporting [Abstract]
Segment Reporting	12. Segment Reporting Effective January 1, 2023, the Company's former Hosted business revenues and gross profit are reported in Other as the business is no longer core to the Company’s operations. There is no change in composition among the Employer Solutions and Professional Services segments. Additionally, the Company changed its measure of segment profit and loss that is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the Company’s segments and assessing business performance. Prior to January 1, 2023, the Company reported its measure of segment profit as earnings before interest, taxes, depreciation and intangible amortization adjusted for the impact of certain non-cash and other items that the Company does not consider in the evaluation of ongoing operational performance. Effective January 1, 2023, the Company's measure of segment profit is gross profit, which is defined as revenue less cost of services. Accordingly, prior period amounts have been reclassified to conform to the current period presentation, in all material respects. The Company’s reportable segments have been determined using a management approach, which is consistent with the basis and manner in which the Company’s chief operating decision maker (“CODM”) uses financial information for the purposes of allocating resources and evaluating performance. The Company’s Chief Executive Officer is its CODM. The CODM evaluates the performance of the Company based on its total revenue and segment profit. The CODM also uses revenue and segment gross profit to manage and evaluate our business, make planning decisions, and as performance measures for Company-wide bonus plans. These key financial measures provide an additional view of our operational performance over the long-term and provide useful information that we use in order to maintain and grow our business. The accounting policies of the segments are the same as those described in Note 2 “Accounting Policies and Practices.” The Company does not report assets by reportable segments as this information is not reviewed by the CODM on a regular basis. Information regarding the Company’s current reportable segments is as follows (in millions): Revenue Three Months Ended September 30 Nine Months Ended September 30 2023 2022 2023 2022 Employer Solutions Recurring $ 634 $ 583 $ 1,942 $ 1,712 Project 67 62 179 170 Total Employer Solutions 701 645 2,121 1,882 Professional Services Recurring 36 32 104 94 Project 69 63 199 182 Total Professional Services 105 95 303 276 Total Reportable Segments 806 740 2,424 2,158 Other 7 10 26 32 Total revenue $ 813 $ 750 $ 2,450 $ 2,190 There was no single client who accounted for more than 10% of the Company’s revenues in any of the periods presented.

To manage the risk related to these exposures, the Company has entered into various derivative instruments that reduce these risks by creating offsetting exposures. Interest Rate Swaps The Company has utilized swap agreements that will fix the floating interest rates associated with its Term Loan as shown in the following table: Designation Date Effective Date Initial Notional Amount Notional Amount Outstanding as of Fixed Rate Expiration Date December 2021 August 2020 $ 181,205,050 $ 518,924,498 0.7203 % April 2024 December 2021 August 2020 $ 388,877,200 $ 647,175,722 0.6826 % April 2024 December 2021 May 2022 $ 220,130,318 $ 270,851,202 0.4570 % April 2024 December 2021 May 2022 $ 306,004,562 $ 345,425,078 0.4480 % April 2024 December 2021 April 2024 $ 871,205,040 n/a 1.6533 % June 2025 December 2021 April 2024 $ 435,602,520 n/a 1.6560 % June 2025 December 2021 April 2024 $ 435,602,520 n/a 1.6650 % June 2025 March 2022 June 2025 $ 1,197,000,000 n/a 2.5540 % December 2026 March 2023 March 2023 $ 150,000,000 $ 150,000,000 3.9025 % December 2026 March 2023 March 2023 $ 150,000,000 $ 150,000,000 3.9100 % December 2026 Concurrent with the refinancing of certain term loans, we amended our interest rate swaps to incorporate Term SOFR. In accordance with ASC Topic 848, Reference Rate Reform , we did not redesignate the interest rate hedges when they were amended from LIBOR to SOFR; as we are permitted to maintain the designation through the transition. During the nine months ended September 30, 2023, we executed two additional interest rate swaps, which have been designated as cash flow hedges. Certain swap agreements amortize or accrete based on achieving targeted hedge ratios. All interest rate swaps have been designated as cash flow hedges. The Company currently has two instruments that the fair value of the instruments at the time of re-designation are being amortized into interest expense over the remaining life of the instruments.

Financial Instruments	14. Financial Instruments Seller Earnouts Upon completion of the Business Combination, the equity owners of Alight Holdings received an earnout in the form of non-voting shares of Class B-1 and Class B-2 Common Stock, which automatically convert into Class A Common Stock if, at any time during the seven years following the Closing Date certain criteria are achieved. See Note 9 “Stockholders’ Equity” for additional information regarding the Seller Earnouts. The portion of the Seller Earnouts related to employee compensation is accounted for as share-based compensation. See Note 10 “Share-Based Compensation Expense” for additional information. The portion of the Seller Earnouts, which are not related to employee compensation, are accounted for as a contingent consideration liability at fair value within Financial instruments on the Condensed Consolidated Balance Sheets because the Seller Earnouts do not meet the criteria for classification within equity. This portion of the Seller Earnouts are subject to remeasurement at each balance sheet date. At September 30, 2023 and December 31, 2022, the Seller Earnouts had a fair value of $ 73 million and $ 96 million , respectively. For the three months ended September 30, 2023 , the fair value remeasurement of the Seller Earnouts was a gain of $ 37 million. For the three months ended September 30, 2022, the Company recorded a loss of $ 10 million related to the fair value remeasurement of the Seller Earnouts. For the nine months ended September 30, 2023 and 2022 , the Company recorded a gain of $ 24 million and a gain of $ 53 million , respectively, related to the remeasurement of the Seller Earnouts. Gains or losses related to the remeasurement of Seller Earnouts are recorded in (Gain) Loss from change in fair value of financial instruments within the accompanying Condensed Consolidated Statements of Comprehensive Income (Loss). The fair value of the Class B-1 and B-2 Seller Earnouts, and the Class Z-B-1 and Z-B-2 contingent consideration instruments, is determined using Monte Carlo simulation and Option Pricing Methods (Level 3 inputs, see Note 16 "Fair Value Measurements"). Significant unobservable inputs are used in the assessment of fair value, including the following assumptions: volatility of 50 % , risk-free interest rate of 4.62 % , expected holding period of 4.76 years and probability assessments based on the likelihood of reaching the performance targets defined in the Business Combination. An increase in the risk-free interest rate or expected volatility would result in an decrease in the fair value measurement of the Seller Earnouts and vice versa. In addition, the Class Z instruments are also accounted for as a contingent consideration liability at fair value within Financial instruments on the Condensed Consolidated Balance Sheets because these instruments do not meet the criteria for classification within equity. The fair value of the Class Z-A contingent consideration is determined using the ending share price as of the last day of each quarter. For the three months ended September 30, 2023, the expense recorded by the Company as a result of the forfeiture of unvested management equity relating to the consideration that will be re-allocated to the holders of Class Z instruments upon vesting was $ 1 million . For the three months ended September 30, 2022, the Company recorded an immaterial change in fair value of financial instruments in the Condensed Consolidated Statements of Comprehensive Income (Loss) as a result of the forfeiture of unvested management equity relating to the consideration that will be re-allocated to the holders of Class Z instruments upon vesting. For the nine months ended September 30, 2023 and 2022, the Company recorded expense of $ 13 million and $ 1 million , respectively, in (Gain) Loss from change in fair value of financial instruments in the Condensed Consolidated Statements of Comprehensive Income (Loss) as a result of the forfeiture of unvested management equity relating to the consideration that will be re-allocated to the holders of Class Z instruments upon vesting.

Tax Receivable Agreement	Sep. 30, 2023
Receivables [Abstract]
Tax Receivable Agreement	15. Tax Receivable Agreement In connection with the Business Combination, Alight entered into the TRA with certain owners of Alight Holdings prior to the Business Combination. Pursuant to the TRA, the Company will pay certain sellers, as applicable, 85% of the tax benefits, of any savings that we realize, calculated using certain assumptions, as a result of (i) tax basis adjustments from sales and exchanges of Alight Holdings equity interests in connection with or following the Business Combination and certain distributions with respect to Alight Holdings equity interests, (ii) our utilization of certain tax attributes, and (iii) certain other tax benefits related to entering into the TRA. Actual tax benefits realized by Alight may differ from tax benefits calculated under the TRA as a result of the use of certain assumptions in the TRA, including the use of an assumed weighted-average state and local income tax rate to calculate tax benefits. While the amount of existing tax basis, the anticipated tax basis adjustments and the actual amount and utilization of tax attributes, as well as the amount and timing of any payments under the TRA, will vary depending upon a number of factors, we expect that the payments that Alight may make under the TRA will be substantial. The Company’s TRA liability established upon completion of the Business Combination is measured at fair value on a recurring basis using significant unobservable inputs (Level 3). The TRA liability balance at September 30, 2023 assumes: (i) a constant blended U.S. federal, state and local income tax rate of 26.4 % ; (ii) no material changes in tax law; (iii) the ability to utilize tax attributes based on current tax forecasts; and (iv) future payments under the TRA are made when due under the TRA. The amount of the expected future payments under the TRA has been discounted to its present value using a discount rate of 9.5 % . Subsequent to the Business Combination, we record additional liabilities under the TRA as and when Class A units of Alight Holdings are exchanged for Class A Common Stock. Liabilities resulting from these exchanges will be recorded on a gross undiscounted basis and are not remeasured at fair value. During the nine months ended September 30, 2023, an additional TRA liability of $ 86 million was established as a result of these exchanges. This amount along with the total impact of exchanges of $ 43 million for the year ended December 31, 2022, are excluded from the portion of the TRA liability that is measured at fair value on a recurring basis. The following table summarizes the changes in the TRA liabilities (in millions): Tax Receivable Agreement Liability Beginning balance as of December 31, 2022 $ 575 Fair value remeasurement 30 Payments ( 7 ) Conversion of noncontrolling interest 86 Ending Balance as of September 30, 2023 684 Less: current portion included in other current liabilities ( 50 ) Total long-term tax receivable agreement liability $ 634

Fair Value Disclosures [Abstract]
Fair Value Measurement	16. Fair Value Measurement Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting standards related to fair value measurements include a hierarchy for information and valuations used in measuring fair value that is broken down into three levels based on reliability, as follows: • Level 1 – observable inputs such as quoted prices in active markets for identical assets and liabilities; • Level 2 – inputs other than quoted prices for identical assets in active markets that are observable either directly or indirectly; and • Level 3 – unobservable inputs in which there is little or no market data which requires the use of valuation techniques and the development of assumptions. The Company’s financial assets and liabilities measured at fair value on a recurring basis are as follows (in millions): September 30, 2023 Level 1 Level 2 Level 3 Total Assets Interest rate swaps $ — $ 122 $ — $ 122 Total assets recorded at fair value $ — $ 122 $ — $ 122 Liabilities Contingent consideration liability $ — $ — $ 8 $ 8 Seller Earnouts liability — — 73 73 Tax receivable agreement liability (1) — — 555 555 Total liabilities recorded at fair value $ — $ — $ 636 $ 636 December 31, 2022 Level 1 Level 2 Level 3 Total Assets Interest rate swaps $ — $ 134 $ — $ 134 Total assets recorded at fair value $ — $ 134 $ — $ 134 Liabilities Contingent consideration liability — — 13 13 Seller Earnouts liability — — 96 96 Tax receivable agreement liability (1) — — 532 532 Total liabilities recorded at fair value $ — $ — $ 641 $ 641 (1) Excludes the portion of liability related to the exchanges of Class A Units not measured at fair value on a recurring basis. Derivatives The valuations of the derivatives intended to mitigate our interest rate risk are determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each instrument. This analysis utilizes observable market-based inputs, including interest rate curves, interest rate volatility, or spot and forward exchange rates, and reflects the contractual terms of these instruments, including the period to maturity. In addition, credit valuation adjustments, which consider the impact of any credit enhancements to the contracts, are incorporated in the fair values to account for potential non-performance risk. Contingent Consideration The contingent consideration liabilities relate to an acquisition completed by the Predecessor in 2018, and are included in Other current liabilities and Other liabilities on the Condensed Consolidated Balance Sheets. The fair value of these liabilities is determined using a discounted cash flow analysis. Changes in the fair value of the liabilities are included in Other (income) expense, net in the Condensed Consolidated Statements of Comprehensive Income (Loss). Significant unobservable inputs are used in the assessment of fair value, including assumptions regarding discount rates and probability assessments based on the likelihood of reaching the various targets set out in the acquisition agreements. The following table summarizes the changes in deferred contingent consideration liabilities (in millions): Three Months Ended September 30 Nine Months Ended September 30 2023 2022 2023 2022 Beginning balance $ 13 $ 25 $ 13 $ 33 Acquisitions — — — — Measurement period adjustments — — — ( 2 ) Accretion of contingent consideration — — — 1 Remeasurement of acquisition-related contingent consideration — ( 2 ) — ( 9 ) Payments ( 5 ) — ( 5 ) — Ending Balance $ 8 $ 23 $ 8 $ 23 Non-Recurring Fair Value Measurements The Company’s financial liabilities not measured at fair value on a recurring basis are as follows (in millions): September 30, 2023 December 31, 2022 Carrying Value Fair Value Carrying Value Fair Value Liabilities Current portion of long-term debt, net $ 25 $ 25 $ 31 $ 31 Long-term debt, net 2,776 2,783 2,792 2,780 Total $ 2,801 $ 2,808 $ 2,823 $ 2,811 The carrying value of the Term Loan, Secured Senior Notes include the outstanding principal balance, less any unamortized premium. The carrying value of the Term Loan approximates fair value as it bears interest at variable rates and we believe our credit risk is consistent with when the debt originated. The outstanding balances under the Senior No tes have fixed interest rates and the fair value is classified as Level 2 within the fair value hierarchy and corroborated by observable market data (see Note 8 “Debt”). The carrying amounts of Cash and cash equivalents, Receivables, net and Accounts payable and accrued liabilities approximate their fair values due to the short-term maturities of these instruments. During the nine months ended September 3 0 , 2023 and 2022, there were no transfers in or out of the Level 1, Level 2 or Level 3 classifications.

Management believes that the reserves established are appropriate based on the facts currently known. The reserves recorded at September 30, 2023 and December 31, 2022 were not significant. Guarantees and Indemnifications The Company provides a variety of service performance guarantees and indemnifications to its clients. The maximum potential amount of future payments represents the notional amounts that could become payable under the guarantees and indemnifications if there were a total default by the guaranteed parties, without consideration of possible recoveries under recourse provisions or other methods. These notional amounts may bear no relationship to the future payments that may be made, if any, for these guarantees and indemnifications.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and should be read in conjunction with the Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the Securities and Exchange Commission (“SEC”) on March 1, 2023. In the opinion of management, all adjustments, including normal recurring adjustments, considered necessary for a fair presentation have been included. All intercompany transactions and balances have been eliminated upon consolidation. The results of operations for interim periods are not necessarily indicative of the results to be expected for future quarters or for the full fiscal year ending December 31, 2023.
Segment Reporting	Segment Reporting Effective January 1, 2023, the Company's former Hosted business revenues and gross margin are reported in Other as the business is no longer core to the Company’s operations. There is no change in composition among the Employer Solutions and Professional Services segments. Additionally, the Company changed its measure of segment profit and loss that is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the Company’s segments and assessing business performance. See Note 12 “Segm ent Reporting” for additional information.
Use of Estimates	Use of Estimates The preparation of the accompanying Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of reserves and expenses. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. Management believes its estimates to be reasonable given the current facts available. Management adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity markets, and foreign currency exchange rate movements increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be predicted with certainty, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment would, if applicable, be reflected in the financial statements in future periods.
New Accounting Pronouncements	New Accounting Pronouncements There are no recently issued accounting pronouncements that are expected to have a material impact upon our Condensed Consolidated Financial Statements.
Fair Value Measurement	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting standards related to fair value measurements include a hierarchy for information and valuations used in measuring fair value that is broken down into three levels based on reliability, as follows: • Level 1 – observable inputs such as quoted prices in active markets for identical assets and liabilities; • Level 2 – inputs other than quoted prices for identical assets in active markets that are observable either directly or indirectly; and • Level 3 – unobservable inputs in which there is little or no market data which requires the use of valuation techniques and the development of assumptions.
