BIRKENSTOCK ANNOUNCES LAUNCH OF SECONDARY OFFERING AND CONCURRENT SHARE REPURCHASE

Birkenstock Holding plc (“BIRKENSTOCK”) announced today the commencement of an underwritten secondary public offering of $1,000 million of BIRKENSTOCK’s ordinary shares (the “Ordinary Shares”) to be sold by BK LC Lux MidCo S.à r.l. (“MidCo”), an entity affiliated with L Catterton (the “Selling Shareholder”). The Selling Shareholder intends to grant the underwriter a 30-day option to purchase up to a number of additional Ordinary Shares equal to 15% of the total number of Ordinary Shares sold by the Selling Shareholder in the offering (including the Ordinary Shares subject to the repurchase described below). BIRKENSTOCK is not selling any Ordinary Shares in the offering and will not receive any proceeds from the sale of the Ordinary Shares being offered by the Selling Shareholder.

Subject to the completion of this offering, BIRKENSTOCK has authorized the repurchase, by way of redemption from the underwriter, of up to $500 million of Ordinary Shares that are subject to this offering, at a price per share equal to the price paid by the underwriter in the offering, with such redeemed Ordinary Shares to be cancelled and no longer outstanding following the completion of the redemption. The underwriter will not receive any underwriting fees for the Ordinary Shares being repurchased by BIRKENSTOCK.

The offering is subject to market and other conditions, and the final number of Ordinary Shares to be sold and the other terms of the offering will be determined at the time of pricing.

J.P. Morgan is acting as underwriter for the proposed offering.

An automatic shelf registration statement on Form F-3ASR (File No. 333-284905) relating to the resale of the Ordinary Shares was previously filed by BIRKENSTOCK with the United States Securities and Exchange Commission (the “SEC”) and became effective upon filing on February 13, 2025 (the “Registration Statement”). A prospectus supplement relating to the offering will be filed with the SEC. Before you invest, you should read the prospectus and the documents incorporated by reference in that Registration Statement, as well as the prospectus supplement related to the offering, for more complete information
