Announcement of Notes Offering

On September 22, 2026, Millrose issued a press release announcing that it plans to offer (the “Offering”) up to $1,000,000,000 in aggregate principal amount of senior notes in two separate tranches, one representing $500,000,000 in aggregate principal amount of senior notes due 2029 and the other representing $500,000,000 in aggregate principal amount of senior notes due 2031 (together, the “Notes”), subject to market conditions. The Offering will be exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The Notes and related guarantees are being offered only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act, and outside the United States to certain non-U.S. persons in reliance on the exemption from registration set forth in Regulation S under the Securities Act. A copy of the press release is being filed as Exhibit 99.1 to this Current Report on Form 8-K (this “Report”) and is incorporated herein by reference.

The Notes and the related guarantees have not been and will not be registered under the Securities Act or the securities laws of any state or other jurisdiction, and the Notes may not be offered or sold in the United States without registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities or blue sky laws and foreign securities laws. This Report shall not constitute an offer to sell, or the solicitation of an offer to buy, any securities, nor shall there be any sales of the Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
