Failure to Satisfy Listing Rule (Form 8-K)

On May 9, 2025, WW International, Inc. (the "Company" or "we") received a written notice (the "Notice") from the Listing Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") notifying the Company that, pursuant to Nasdaq Listing Rules 5101, 5110(b) and IM-5101-1,Nasdaq had determined to delist the Company's common stock as a result of the Company and certain of its subsidiaries commencing voluntary prepackaged cases under chapter 11 of title 11 of the United States Code, on May 6, 2025 (the "Chapter 11 Cases"). Pursuant to Nasdaq listing rules, the Company has the right to appeal Nasdaq's delisting determination.

The Notice further advises that Nasdaq will suspend trading of the Company's common stock at the opening of business on May 16, 2025 and that Nasdaq will file a Form 25-NSEwith the Securities and Exchange Commission (the "SEC") to effect the delisting of the Company's common stock unless the Company requests an appeal of this determination. The Company intends to seek to list, on Nasdaq or another national stock exchange, the new common equity of the reorganized Company that is expected to be issued pursuant to the plan of reorganization for the Chapter 11 Cases on or as soon as possible after the emergence from the Chapter 11 Cases.

The Company anticipates that following suspension from trading, its common stock will commence trading on the Pink Current Market, operated by OTC Markets Group. The transition to the over-the-countermarket is not expected to affect the Company's business operations. The Company can provide no assurance that the common stock will commence or continue to trade on this market, whether broker-dealers will continue to provide public quotes of the common stock on this market, whether the trading volume of the common stock will be sufficient to provide for an efficient trading market or whether quotes for the common stock will continue on this market in the future.
