Chewy, Inc. Announces Public Offering of Class A Common Stock by Selling Stockholder and Concurrent Share Repurchase

PLANTATION, Fla. – (BUSINESS WIRE) – September 19, 2024 – Chewy, Inc. (NYSE: CHWY) (“Chewy”), a trusted destination for pet parents and partners everywhere, announced today the commencement of an underwritten offering of $500 million of shares of its Class A common stock, par value $0.01 per share, by Buddy Chester Sub LLC (the “Selling Stockholder”), which is an entity affiliated with funds advised by BC Partners Advisors LP (“BC Partners”), Chewy’s largest shareholder (the “Offering”). The Selling Stockholder intends to grant the underwriters a 30-day option to purchase up to an additional $75 million of shares of Class A common stock. Chewy will not sell any shares of its Class A common stock in the Offering and will not receive any proceeds from the sale of the shares of Class A common stock being offered by the Selling Stockholder. The Offering is subject to market and other conditions, and there can be no assurance as to whether or when the Offering may be completed.

In addition, Chewy has agreed to purchase from the Selling Stockholder $300 million of Chewy’s Class A common stock at a price per share equal to the per share purchase price to be paid by the underwriters in the Offering specified above (the “Concurrent Repurchase”). The Concurrent Repurchase was approved by a special committee of Chewy’s Board of Directors, consisting solely of independent and disinterested directors not affiliated with BC Partners. The repurchased shares will be cancelled and retired upon completion of the Concurrent Repurchase. The Concurrent Repurchase is being executed separately from the Company’s existing $500 million share repurchase program authorized on May 24, 2024, which will be unaffected by this transaction. The Concurrent Repurchase is expected to be consummated concurrently with the Offering. The Offering is not conditioned upon the closing of the Concurrent Repurchase, but the Concurrent Repurchase is conditioned upon the closing of the Offering.

Morgan Stanley is acting as lead book-running manager for the Offering. Chewy has filed a registration statement (including a prospectus) with the Securities and Exchange Commission (the “SEC”) for the Offering. Before you invest, you should read the prospectus in that registration statement and other documents Chewy has filed with the SEC for more complete information about Chewy and the Offering.
