Item 8.01 Other Events.

On March 1, 2023, Alight, Inc. (the “Company”) entered into an Underwriting Agreement (the “Underwriting Agreement”), among the Company, Alight Holding Company, LLC, certain funds affiliated with Blackstone Inc., Jasmine Ventures Pte. Ltd., Platinum Falcon B 2018 RSC Ltd. and certain funds affiliated with New Mountain Capital (collectively, the “Selling Stockholders”) and J.P. Morgan Securities LLC and BofA Securities, Inc., as representatives of the several underwriters named therein (collectively, the “Underwriters”). The Underwriting Agreement relates to the underwritten secondary public offering of 46,000,000 shares of the Company’s Class A common stock by the 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. The offering was made pursuant to the Company’s registration statement on Form S-1 (Registration No. 333-258350), as amended, initially filed with the Securities and Exchange Commission on August 2, 2021. The offering, including the shares of Class A common stock sold pursuant to the Underwriters' option, settled and closed on March 6, 2023.

Concurrently with this offering, the Company closed the repurchase from the Selling Stockholders, in privately negotiated transactions, pursuant to a repurchase agreement of an aggregate of 1,148,435 shares of Class A common stock at a price equal to the price per share at which the Underwriters purchased shares of Class A common stock from the selling stockholders in this offering.

The foregoing summary of the Underwriting Agreement is qualified by reference to the Underwriting Agreement, which is filed as exhibit 1.1 to this Current Report on Form 8-K.
