Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Nature of Business	1. Basis of Presentation and Nature of Business 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, 2023, filed with the Securities and Exchange Commission (“SEC”) on February 29, 2024. 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. 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 June 30, 2024, Alight owned approximately 99% 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 less than 1% as of June 30, 2024. On July 12, 2024, Alight, Inc. (together with its subsidiaries, the “Company” or “Alight”) and Tempo Acquisition LLC, a subsidiary of the Company, completed the previously announced sale (the “Transaction”) of Alight’s Professional Services segment and Alight’s Payroll & HCM Outsourcing business within the Employer Solutions segment (collectively, the “Divested Business”) to Axiom Buyer, LLC, a newly-formed entity and an affiliate of H.I.G. Capital, L.L.C. (“Buyer”), pursuant to the terms of the Stock and Asset Purchase Agreement (the “Purchase Agreement”), dated as of March 20, 2024. As a result of this agreement, the results of the Company’s Payroll and Professional Services businesses are reported separately as discontinued operations, net of tax, in our condensed consolidated statements of comprehensive income (loss) for all periods presented and its assets and liabilities are presented in our condensed consolidated balance sheets as assets and liabilities held for sale as of June 30, 2024.

Accounting Policies [Abstract]
Accounting Policies and Practices	2. Accounting Policies and Practices Significant Accounting Policies There have been no material changes to our significant accounting policies from our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. 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 Not Yet Adopted In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires an enhanced disclosure of significant segment expenses on an annual and interim basis. This guidance will be effective for the annual periods beginning the year ended December 31, 2024, and for interim periods beginning January 1, 2025. Early adoption is permitted. Upon adoption, the guidance should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the standard to determine the impact of adoption to its condensed consolidated financial statements and disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the annual periods beginning the year ended December 31, 2025. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company is currently evaluating the standard to determine the impact of adoption to its condensed consolidated financial statements and disclosures.

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 and are therefore less predictable on an annual basis. See Note 12 “Segment Reporting” for quantitative disclosures of recurring and project revenues by reportable segment. The Company’s reportable segment is Employer Solutions. Employer Solutions is 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. The Company believes the revenue categories within Employer Solutions 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 and human resource services across all of our solutions, which are highly recurring. The Company’s contracts may include administration services across one or multiple solutions and typically have three five These contracts typically consist of an implementation phase and an ongoing administration phase: Implementation phase – In connection with the Company’s long-term agreements, implementation efforts are often necessary to set up clients and their human resource 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 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 the activities are performed 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 the 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. 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 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 generally 7 years for our leaves 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 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 generally 7 years for our leaves 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”.

(2) The net balance for the Fifth Incremental Term Loans includes unamortized debt issuance costs at December 31, 2023 of approximately $8 million. Term Loan In May 2017, the Company entered into a 7 year Initial Term Loan. During November 2017 and November 2019, the Company entered into Incremental Term Loans under identical terms as the Initial Term Loan. 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. In August 2021, the Company entered into a new Third Incremental Term Loan facility for $525 million that matures August 31, 2028. In January 2022, the Company refinanced the Amended Term Loan and the Third Incremental Term Loan to have a concurrent maturity date of August 31, 2028 and updated interest rate terms as described below (the "B-1 Term Loan"). In June 2023, the Company refinanced the remaining portion of the 7 year Term Loan in full by increasing the existing B-1 Term Loan by approximately $65 million under identical terms as the B-1 Term Loan. Interest rates on the B-1 Term Loan borrowings are based on the Secured Overnight Financing Rate ("SOFR") plus a margin. The Company is required to make principal payments at the end of each fiscal quarter based on defined terms in the agreement with the remaining principal balances due on the maturity dates. In September 2023, the Company entered into Amendment No. 9 to Credit Agreement with a syndicate of lenders to establish a new class of Fifth Incremental Term Loans with an aggregate principal amount of $2,507 million to reprice the outstanding Initial Term B-1 Loans due August 31, 2028 by reducing the applicable rate from SOFR + 3.00% to SOFR + 2.75%.

The Company utilized swap agreements to fix a portion of the floating interest rates through December 2026 (see Note 13 “Derivative Financial Instruments”). During the three and six months ended June 30, 2024, the Company made total principal payments of $6 million and $13 million, respectively. During the three and six months ended June 30, 2023 the Company made total principal payments $6 million and $13 million, respectively. In July 2024, the Company paid down $440 million of the Sixth Incremental Term Loans principal balance with proceeds from the Transaction .

In July 2024, the Company paid the remaining Secured Senior Notes principal balance of $300 million with proceeds from the Transaction.

During August 2020, the Company extended the maturity date for $226 million of the revolving credit facility to October 31, 2024. In August 2021, the Company replaced and refinanced the revolving credit facilities with a $294 million revolving credit facility with a maturity date of August 31, 2026. In March 2023, the Company amended and upsized the revolving credit facility to $300 million and updated the benchmark reference rate from LIBOR to Term SOFR. No changes were made to the maturity date. At June 30, 2024, approximately $3 million of unused letters of credit related to various insurance policies and real estate leases were issued under the revolving credit facility and there were no borrowings. The Company is required to make periodic payments for commitment fees and interest related to the revolving credit facility and outstanding letters of credit.

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, recapitalization and exercises of the exchange rights of holders of Alight Holdings units. Exchange of Class A Units During the six months ended June 30, 2024, 634,588 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 Tax Receivable Agreement (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 $89 million, with offsets to Additional paid-in-capital. An additional $18 million increase to Additional paid-in-capital was due to exchanges as a result of deferred tax assets due to our change in ownership. 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 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. On March 20, 2024, the Company’s Board of Directors authorized the repurchase of up to an additional $200 million of the Company’s Class A common stock, providing a total amount authorized for repurchase of $248 million. During the three and six months ended June 30, 2024, there were 10,134,600 Class A Common Stock shares repurchased under the Program. Repurchased shares are reflected as Treasury Stock on the Condensed Consolidated Balance Sheets as a component of equity. As of June 30, 2024, the total amount authorized for repurchase remaining was $168 million. Accelerated Share Repurchase On June 18, 2024, the Company announced that it entered into an accelerated share repurchase agreement (the "ASR") with Barclays Bank PLC (the "ASR counterparty") to repurchase $75 million of Alight's Class A Common Stock, as part of the Company's existing share repurchase program. On July 16, 2024, the Company made an initial payment of $75 million to the ASR counterparty and received an initial delivery of shares equal in value to 80% of the prepayment amount of $75 million, based on Alight’s closing share price as of the effective date of July 15, 2024. The final number of shares to be repurchased will be based on the volume-weighted average price of Alight's common stock during the term of the transaction, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR. The final settlement of the transaction under the ASR is expected to occur during the third quarter of 2024. 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, 2023 507,567,678 4,951,235 4,951,235 28,962,218 3,420,215 6,427,853 Conversion of noncontrolling interest 27,773,062 — — (27,773,062) — — Shares granted upon vesting 13,890,962 — — — (2,842,116) — Issuance for compensation to non-employees (1) 17,802 — — — — — Share repurchases — — — — — — Share forfeitures — (18,148) (18,148) — — — Balance at March 31, 2024 549,249,504 4,933,087 4,933,087 1,189,156 578,099 6,427,853 Conversion of noncontrolling interest 634,588 — — (634,588) — — Shares granted upon vesting 954,218 — — — — — Issuance for compensation to non-employees (1) 100,678 — — — — — Share repurchases (10,134,600) — — — — 10,134,600 Share forfeitures — (18,148) (18,148) — — — Balance at June 30, 2024 540,804,388 4,914,939 4,914,939 554,568 578,099 16,562,453 _______________________________________________________ (1) Issued to certain members of the Board of Directors in lieu of cash retainer.

Accumulated Other Comprehensive Income As of June 30, 2024, 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 Payment Arrangement [Abstract]
Share-Based Compensation	10. Share-Based Compensation The Company has an active equity incentive plan, the Alight, Inc. 2021 Omnibus Incentive Plan (the "Incentive Plan"), under which the Company has been authorized to grant share-based awards to key employees and non-employee directors, which consist of restricted stock units ("RSUs") and performance share units ("PRSUs"). Under this plan, for grants issued during the six months ended June 30, 2024, approximately 43% of the units are subject to time-based vesting requi rements and approximately 57% are subject to performance-based vesting requirements. As of June 30, 2024, there were 79,713,256 remaining shares of common stock authorized for issuance pursuant to the Company’s stock-based compensation plans under its 2021 Omnibus Incentive Plan. Restricted Share Units and Performance Based Restricted Share Units RSUs are valued at the market price of a share of the Company’s common stock on the date of grant. In general, these awards vest ratably over a three-year period from the date of grant. All awards are expensed on a straight-line basis over a three-year period, which is considered to be the requisite service period. The Company’s PRSUs contain various performance and service conditions that must be satisfied for an employee to earn the right to benefit from the award. The PRSUs vest upon achievement of various performance metrics aligned to goals established by the Company. Expense is recognized on a straight-line basis over the requisite service period, based on the probability of achieving the performance conditions, with changes in expectations recognized as an adjustment to earnings in the period of the change. Compensation cost is not recognized for performance share units that do not vest because service or performance conditions are not satisfied, and any previously recognized compensation cost is reversed. The weighted-average grant-date fair value per share of RSUs and PRSUs granted during the six months ended June 30, 2024 was approximately $8.94 and $8.81, respectively. The following table summarizes the RSU and PRSU activity during the six months ended June 30, 2024: RSUs Weighted Average Grant Date Fair Value Per Unit PRSUs (1) Weighted Average Grant Date Fair Value Per Unit Balance as of December 31, 2023 8,174,812 $ 9.78 28,041,674 $ 11.25 Granted 4,782,855 8.94 6,465,569 8.81 Vested (2,984,063) 8.98 (19,755,498) 12.28 Forfeited (376,084) 8.92 (639,365) 8.85 Balance as of June 30, 2024 9,597,520 $ 8.84 14,112,381 $ 8.85 _______________________________________________________ (1) The number of PRSUs presented are based on actual or expected achievement of the respective performance goals as of the end of the period. The Company forfeited approximately 3.5 million shares in July 2024 in conjunction with the Transaction as discussed in Note 1 "Basis of Presentation and Nature of Business". Share-based Compensation Expense Total share-based compensation expense related to the RSUs and PRSUs are recorded in the Condensed Consolidated Statements of Comprehensive Income (Loss) as follows (in millions): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Cost of services, exclusive of depreciation and amortization $ 3 $ 7 $ 8 $ 14 Selling, general and administrative 17 23 40 50 Total share-based compensation expense $ 20 $ 30 $ 48 $ 64 As of June 30, 2024, total future compensation expense related to unvested RSUs was $71 million, which will be recognized over a remaining weighted-average amortization period of approximately 2.07 years. As of June 30, 2024, total future compensation expense related to PRSUs was $76 million, which will be recognized over a remaining weighted-average amortization period of approximately 1.78 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 . As of June 30, 2024, there were 12,692,122 remaining shares available for grant and 2,268,910 shares issued under the ESPP. The amount of share-based compensation expense related to the ESPP was approximately $0.3 million and $0.8 million for the three and six months ended June 30, 2024, respectively.

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. Basic and diluted (net loss) earnings per share are as follows (in millions, except for share and per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Basic and diluted (net loss) earnings per share: Numerator Net Income (Loss) From Continuing Operations $ (4) $ (72) $ (125) $ (156) Less: Net loss attributable to noncontrolling interest — 5 2 11 Net Income (loss) from continuing operations attributable to Alight, Inc. $ (4) $ (67) $ (123) $ (145) Net Income (Loss) From Discontinued Operations, Net of Tax 27 — 32 10 Net Income (Loss) Attributable to Alight, Inc. - basic $ 23 $ (67) $ (91) $ (135) Loss impact of conversion of noncontrolling interest — — (1) — Net income (loss) attributable to Alight, Inc. - diluted $ 23 $ (67) $ (92) $ (135) Denominator Weighted-average shares outstanding - basic 546,174,400 490,306,205 543,376,024 483,358,533 Dilutive effect of the exchange of noncontrolling interest units 554,568 — 554,568 — Dilutive effect of RSUs 374,688 — — — Weighted-average shares outstanding - diluted 547,103,656 490,306,205 543,930,592 483,358,533 Basic and Diluted (net loss) earnings per share Continuing operations $ (0.01) $ (0.14) $ (0.23) $ (0.30) Discontinued operations $ 0.05 $ 0.00 $ 0.06 $ 0.02 Net Income (Loss) $ 0.04 $ (0.14) $ (0.17) $ (0.28) F or the three and six months ended June 30, 2023, 44,077,108 units 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 both the three and six months ended June 30, 2024, 9,222,832 and 9,597,520, respectively, of unvested RSUs were not included in the computation of diluted shares outstanding as their impact would have been anti-dilutive. For both the three and six months ended June 30, 2023, 10,109,595 of unvested RSUs were not included in the computation of diluted shares outstanding as their impact would have been anti-dilutive. For the three and six months ended June 30, 2024 and 2023 14,112,381 unvested PRSUs and 30,228,371 unvested PRSUs, respectively, were excluded from the calculation of basic and diluted earnings per share. For both the three and six months ended June 30, 2024 and 2023, these unvested PSU shares reflect current 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 As disclosed above in Note 1 “Basis of Presentation and Nature of Business”, on July 12, 2024, the Company closed on its previously announced sale of the Divested Business. As a result of the Transaction, the Company has determined it has one remaining reportable segment, Employer Solutions. See Notes 1 “Basis of Presentation and Nature of Business” and Note 4 “Discontinued Operations and Assets Held for Sale” for additional information. 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 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 reportable segment revenue is as follows (in millions): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Employer Solutions Recurring $ 493 $ 505 $ 1,014 $ 1,038 Project 45 47 83 90 Total Employer Solutions 538 552 1,097 1,128 Other — 9 — 19 Total revenue $ 538 $ 561 $ 1,097 $ 1,147 There was no single client who accounted for more than 10% of the Company’s revenues in any of the periods presented.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	13. Derivative Financial Instruments The Company is exposed to market risks, including changes in interest rates. 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 June 30, 2024 Fixed Rate Expiration Date December 2021 April 2024 $ 871,205,040 $ 868,851,160 1.6533 % June 2025 December 2021 April 2024 $ 435,602,520 $ 434,425,580 1.6560 % June 2025 December 2021 April 2024 $ 435,602,520 $ 434,425,580 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 Accounting Standards Codification 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 six months ended June 30, 2024, we have not executed any new interest rate swaps. Our interest rate swaps 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 [Abstract]
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 June 30, 2024 and December 31, 2023, the Seller Earnouts had a fair value of $66 million and $95 million, respectively. For the three months ended June 30, 2024, the fair value remeasurement of the Seller Earnouts was a gain of $48 million . For the three months ended June 30, 2023, the fair value remeasurement of the Seller Earnouts was not material. For the six months ended June 30, 2024 and 2023 , the fair value remeasurement of the Seller Earnouts was a gain of $29 million and a loss of $13 million, respectively. 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 45%, risk-free interest rate of 4.42%, expected holding period of 4.01 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 increase 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. At June 30, 2024 and December 31, 2023, the Class Z-A contingent consideration had a fair value of $11 million and $13 million, respectively. For the three months ended June 30, 2024, 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 a gain of $4 million. For the three

Tax Receivable Agreement

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 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 June 30, 2024 assumes: (i) a blended U.S. federal, state and local income tax rate of 23.8%; (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 7.5%. 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 six months ended June 30, 2024, an additional TRA liability of $89 million was established as a result of these exchanges. As of June 30, 2024, $606 million of the TRA liability is measured at fair value on a recurring basis and $240 million is undiscounted and not remeasured at fair value. The following table summarizes the changes in the TRA liabilities (in millions): Tax Receivable Agreement Liability Beginning balance as of December 31, 2023 $ 795 Fair value remeasurement 24 Payments (62) Conversion of noncontrolling interest 89 Ending Balance as of June 30, 2024 846 Less: current portion included in other current liabilities (89) Total long-term tax receivable agreement liability $ 757

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): June 30, 2024 Level 1 Level 2 Level 3 Total Assets Interest rate swaps $ — $ 66 $ — $ 66 Total assets recorded at fair value $ — $ 66 $ — $ 66 Liabilities Interest rate swaps $ — $ — $ — $ — Contingent consideration liability — — 3 3 Seller Earnouts liability — — 66 66 Tax receivable agreement liability (1) — — 606 606 Total liabilities recorded at fair value $ — $ — $ 675 $ 675 December 31, 2023 Level 1 Level 2 Level 3 Total Assets Interest rate swaps $ — $ 77 $ — $ 77 Total assets recorded at fair value $ — $ 77 $ — $ 77 Liabilities Interest rate swaps — 3 — 3 Contingent consideration liability — — 3 3 Seller Earnouts liability — — 95 95 Tax receivable agreement liability (1) — — 634 634 Total liabilities recorded at fair value $ — $ 3 $ 732 $ 735 _________________________________________________________ (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 acquisitions in previous years and are included in Other current 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). Level 3 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 respective acquisition agreements. The following table summarizes the changes in deferred contingent consideration liabilities (in millions): Three Months Ended Six Months Ended 2024 2023 2024 2023 Beginning balance $ 3 $ 13 $ 3 $ 13 Remeasurement of acquisition-related contingent consideration — — — — Payments — — — — Ending Balance $ 3 $ 13 $ 3 $ 13 Additional Disclosures Regarding Fair Value Measurement The fair value of the Company’s debt is classified as Level 2 within the fair value hierarchy and corroborated by observable market data is as follows (in millions): June 30, 2024 December 31, 2023 Carrying Value Fair Value Carrying Value Fair Value Liabilities Current portion of long-term debt, net $ 329 $ 328 $ 25 $ 25 Long-term debt, net 2,451 2,462 2,769 2,780 Total $ 2,780 $ 2,790 $ 2,794 $ 2,805 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 Notes 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 each of the six months ended June 30, 2024 and 2023, there were no transfers in or out of the Level 1, Level 2 or Level 3 classifications.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring Transformation Program On February 20, 2023, the Company approved a two-year strategic transformation restructuring program (the “Transformation Program”) intended to accelerate the Company’s back-office infrastructure into the cloud and transform its operating model leveraging technology in order to reduce its overall future costs. The Transformation Program includes process and system optimization, third party costs associated with technology infrastructure transformation, and elimination of full-time positions. The Company currently expects to record in the aggregate approximately $135 million in pre-tax restructuring charges over the two-year period. The restructuring charges are expected to include severance charges with an estimated range from $35 million to $45 million over the two-year period and other restructuring charges related to items such as data center exit costs, third party fees, and costs associated with transitioning existing technology and processes with an estimated range of $90 million to $100 million over the two-year period. The Company estimates an annual savings of over $75 million after the Transformation Program is completed. The Transformation Program commenced in the first quarter of 2023 and is expected to be substantially completed over an estimated two-year period. From the inception of the plan through June 30, 2024, the Company has incurred total expenses of $121 million. These charges are recorded in Selling, general and administrative expenses in the Condensed Consolidated Statements of Comprehensive Income (Loss).The following table summarizes restructuring costs by type that have been incurred.

Commitments and Contingencies	19. Commitments and Contingencies Legal The Company is subject to various claims, tax assessments, lawsuits, and proceedings that arise in the ordinary course of business relating to the delivery of our services and the effectiveness of our technologies. The damages claimed in these matters are or may be substantial. Accruals for any exposures, and related insurance or other receivables, when applicable, are included on the Condensed Consolidated Balance Sheets and have been recognized in Selling, general and administrative expenses in the Condensed Consolidated Statements of Comprehensive Income (Loss) to the extent that losses are deemed probable and are reasonably estimable. These amounts are adjusted from time to time as developments warrant. Management believes that the reserves established are appropriate based on the facts currently known. Management believes that the reserves established are appropriate based on the facts currently known. The reserves recorded at June 30, 2024 and December 31, 2023 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. To date, the Company has not been required to make any payment under any client arrangement as described above. The Company has assessed the current status of performance risk related to the client arrangements with performance guarantees and believes that any potential payments would be immaterial to the Condensed Consolidated Financial Statements. Purchase Obligations In March 2024, the Company entered into an agreement with a third-party provider in the ordinary course of business for the use of certain cloud services. Under this agreement, the Company is committed to purchase services totaling $250 million over a 5-year term. The Company’s total expected cash outflow for non-cancellable purchase obligations related to purchases of information technology assets and services, including the new agreement, is $35 million, $59 million, $54 million, $54 million, $50 million, and $13 million for the remainder of 2024 and the years ended 2025, 2026, 2027, 2028, and thereafter, respectively. Service Obligations On September 1, 2018, the Company executed an agreement to form a strategic partnership with Wipro, a leading global information technology, consulting and business process services company. The Company’s expected cash outflow for non-cancellable service obligations related to our strategic partnership with Wipro is $78 million, $162 million, $170 million, $178 million, $154 million for the remainder of 2024 and the years ended 2025, 2026, 2027, 2028, respectively, and none thereafter.

Consolidation	All intercompany transactions and balances have been eliminated upon consolidation.
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 Not Yet Adopted	New Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires an enhanced disclosure of significant segment expenses on an annual and interim basis. This guidance will be effective for the annual periods beginning the year ended December 31, 2024, and for interim periods beginning January 1, 2025. Early adoption is permitted. Upon adoption, the guidance should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the standard to determine the impact of adoption to its condensed consolidated financial statements and disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the annual periods beginning the year ended December 31, 2025. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company is currently evaluating the standard to determine the impact of adoption to its condensed consolidated financial statements and disclosures.
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.
