Los Angeles, United States and Berlin, Germany (December 10, 2021) – Yucaipa Acquisition Corporation (“Yucaipa” or “YAC”) (NYSE: YAC), a special purpose acquisition company, today announced that, subject to shareholder approval, it expects all conditions to be met or waived to complete its previously announced business combination with SIGNA Sports United (“SSU” or the “Company”), the world’s leading sports e-commerce and technology platform.

The transaction is expected to raise at least $484 million from YAC trust proceeds and a fully committed, upsized private placement of common stock (PIPE) from institutional and high-tech investors, sovereign wealth funds and high net-worth individuals.

Stephan Zoll, CEO of SSU, said “We’re delighted to be on the verge of closing the transaction and are ready to start the next stage of the SSU story. This important step enables us to build upon the strength of our technology and infrastructure platform and further grow our position in the global sports e-commerce market.”

Mike Özkan, designated Chairman of the Board of SSU, said, “With the anticipated closing of the business combination as well as the Wiggle Chain Reaction Cycles acquisition, SSU is taking its next step to further accelerate its global expansion as a NYSE listed company. The listing will allow us to accelerate the strategic consolidation of the sports e-commerce & technology sector.”

Ron Burkle, Chairman and President of Yucaipa, said, “We are pleased we are in a position to close the combination and open the next chapter. We look forward to supporting the experienced SSU team on this exciting journey as a public company.”

As previously disclosed, the Company believes its short-term revenue growth targets for the current fiscal year will be adversely affected by the on-going COVID-19 related supply chain disruptions and will likely land in the range of €1.40B—€1.55BN on a full-year pro forma basis. However, the Company reiterates that it is very confident demand remains strong, the strategic consolidation opportunities are huge and the mid and long-term mega-trends behind the business are accelerating. The Company expects to continue on its strong growth track once the COVID-19 related supply chain situation normalizes.

YAC shareholders who have elected to redeem their shares may withdraw their redemption requests at any time until the vote in connection with the business combination is taken at the extraordinary general meeting of YAC shareholders (the “General Meeting”), which is scheduled to occur at 10:00 a.m. New York City time, on December 13, 2021 at the offices of Kirkland & Ellis LLP located at 601 Lexington Avenue, 50th Floor, New York, New York 10022, and via a live webcast at https://www.cstproxy.com/yucaipayac/2021.
