Amendment Description This Amendment No. 1 on Form 10-K/A (the “Amendment”) amends the Annual Report on Form 10-K of WW International, Inc. (the “Company”) for the fiscal year ended January 2, 2021, as filed with the Securities and Exchange Commission on February 25, 2021 (the “Original Filing”).   This Amendment is being filed solely to update the Report of Independent Registered Public Accounting Firm (the “Report”) to include a reference to the Company’s financial statement schedule which is listed in the index appearing under Item 8 of the Original Filing. Due to an inadvertent oversight by the Company’s independent registered public accounting firm, the reference to the financial statement schedule in the Report was omitted in the Original Filing. The updated Report does not modify PricewaterhouseCoopers LLP’s unqualified opinion on the Company’s consolidated financial statements included in the Original Filing.   In accordance with Rule 12b-15 of the Securities Exchange Act of 1934, as amended, this Amendment includes new certifications required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, as amended, dated as of the filing date of this Amendment. In addition, the consent filed as Exhibit 23.1 to this Amendment is dated as of the filing date of this Amendment.   Other than as expressly described above, no changes have been made to the Original Filing. This Amendment does not reflect events occurring after the Original Filing.    
Documents Incorporated by Reference Portions of the registrant’s definitive Proxy Statement for its 2021 annual meeting of shareholders are incorporated herein by reference in Part III, Items 10-14. Such Proxy Statement will be filed with the SEC no later than 120 days after the registrant’s fiscal year ended January 2, 2021.
