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, 2025, filed with the Securities and Exchange Commission (“SEC”) on February 24, 2026. 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, 2026, 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, 2026. On July 12, 2024, the Company, completed the sale (the “Transaction”) of Alight's Payroll & HCM Outsourcing business (the "Divestiture" or "Divested Business") within the Employer Solutions segment. 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 financial statements for all periods presented. Reverse Stock Split At Alight's 2026 Annual Meeting of Stockholders held on June 10, 2026, stockholders approved a reverse stock split of Alight's outstanding common stock and a corresponding decrease in the number of authorized shares of each class and series of common stock (the "Reverse Stock Split"). On June 10, 2026, the Company's Board of Directors determined to effectuate the Reverse Stock Split at a ratio of 1-for-20. The Reverse Stock Split became effective as of Tuesday, June 30, 2026, at 5:00 p.m. Eastern Time (the "Effective Time"). Alight’s Class A Common Stock began trading on a split-adjusted basis on the NYSE under the existing symbol (ALIT) when the market opened on Wednesday, July 1, 2026. As of the Effective Time, every 20 issued and outstanding shares of Alight’s Class A Common Stock, Class B non-voting common stock (including Class B-1 Common Stock and Class B-2 Common Stock), and Class V Common Stock was reclassified into one issued and outstanding share of Alight’s Class A Common Stock, Class B non-voting common stock (including Class B-1 Common Stock and Class B-2 Common Stock), and Class V Common Stock, respectively. Additionally, the total number of shares Alight is authorized to issue and number of authorized shares of Class A Common Stock, Class B non-voting common stock (including Class B-1 Common Stock, Class B-2 Common Stock and Class B-3 Common Stock), Class V Common Stock and Class Z non-voting common stock (including the Class Z-A Common Stock, Class Z-B-1 Common Stock and Class Z-B-2 Common Stock) was correspondingly decreased. Proportionate adjustments were also made to Alight’s outstanding equity-based awards and equity plans as well as to the outstanding limited liability company units of Alight Holdings in accordance with the terms of the applicable agreements. No fractional shares were issued as a result of the reverse stock split. Stockholders otherwise entitled to receive a fractional share as a result of the Reverse Stock Split received a cash payment in an amount equal to the fair value thereof as of the Effective Time (as determined by the Board and without interest) in lieu of such fractional shares. The Company's total stockholder's equity and the par value of each class and series of the Company’s common stock did not change as a result of the Reverse Stock Split. All issued and outstanding common stock, authorized share, share price, weighted average shares outstanding, earnings (loss) per share, share-based compensation awards, outstanding Alight Holdings units and per share amounts contained in this Quarterly Report on Form 10-Q have been adjusted retroactively to reflect the Reverse Stock Split for all periods presented.
