•

Registration Statement on Form S-8 (No. 333-258475) pertaining to the registration of 6,374,273 Shares reserved for issuance in respect of awards to be granted under the European Wax Center, Inc. 2021 Omnibus Incentive Plan.

The Registrant is filing these Post-Effective Amendments to withdraw and remove any unissued and unsold securities issuable by the Registrant pursuant to the above referenced Registration Statements.

On February 9, 2026, the Registrant entered into an Agreement and Plan of Merger (as it may be amended, supplemented or modified from time to time) (the "Merger Agreement"), by and among Glow Midco, LLC, a Delaware limited liability company ("Parent"), Glow Merger Sub 1, Inc., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub Inc."), Glow Merger Sub 2, LLC, a Delaware limited liability company and wholly owned subsidiary of Parent ("Merger Sub LLC," together with Merger Sub Inc., the "Merger Subs," and the Merger Subs together with Parent, the "Buyer Parties"), the Registrant and EWC Ventures, LLC, a Delaware limited liability company ("Opco"), pursuant to which (i) Merger Sub Inc. merged with and into the Registrant (the "Corporate Merger"), with the Registrant surviving the Corporate Merger as the surviving corporation and a wholly owned subsidiary of Parent and (ii) Merger Sub LLC merged with and into Opco, with Opco surviving as the surviving limited liability company and a wholly owned subsidiary of Parent (the "LLC Merger", and together with the Corporate Merger, the "Mergers").

As a result of the Mergers, the Registrant has terminated all offerings of its securities pursuant to the Registration Statements. In accordance with an undertaking made by the Registrant in each of the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance that remain unsold at the termination of the offerings, the Registrant hereby removes from registration all such securities registered under the Registration Statements that remain unsold as of the date hereof and terminates the effectiveness of the Registration Statements.
