Yucaipa Acquisition Corporation Shareholders Approve Business

Combination Transaction with SIGNA Sports United

Berlin, Germany and Los Angeles, California (December 13, 2021) – Yucaipa Acquisition Corporation (NYSE: YAC) (“Yucaipa”), a publicly-traded special purpose acquisition company led by Chairman and President Ron Burkle and CFO and COO Ira Tochner, and SIGNA Sports United (“SSU”), a leading global sports, e-commerce and technology platform, today announced that its respective shareholders approved the business combination between Yucaipa and SSU announced on June 11, 2021. The business combination also includes the acquisition of the WiggleCRC Group (“WiggleCRC”), the second largest online bike retailer globally after SSU, currently owned by Bridgepoint. The respective boards of directors of both Yucaipa and SSU had previously approved the business combination.

Following the Yucaipa shareholder vote, SSU and Yucaipa have commenced final procedures towards the closing of the business combination and expect the closing to be completed by December 14, 2021. It is further expected that the trading of the shares of the combined company, called SIGNA Sports United N.V. (formerly known as SIGNA Sports United B.V., “Pubco”), will commence on the New York Stock Exchange under the symbol “SSU” on the first trading day thereafter. SSU will continue to operate under its existing management team led by Chief Executive Officer, Stephan Zoll.

Transaction Overview

Yucaipa has agreed to combine with SSU and WiggleCRC based on a $3.2 billion pro forma enterprise valuation.

The transaction is expected to raise at least $484 million from Yucaipa trust proceeds and a fully committed ordinary share private investment in public equity (“PIPE”) from institutional and high-tech investors, sovereign wealth funds and high net-worth individuals.

Ron Burkle and SIGNA International Sports Holding GmbH (“SISH”), the majority shareholder of SSU, are both investing in the PIPE and are joined by top tier global institutional investors. The existing shareholders have agreed to convert 100 percent of their ownership stakes into the new public company.

Additional information about the proposed transaction, including a copy of the business combination agreement and an investor presentation, has been provided in a current report on Form 8-K filed by Yucaipa with the United States Securities and Exchange Commission (the “SEC”) and available at www.sec.gov, on SSU’s website at https://ir.signa-sportsunited.com/ and on Yucaipa’s website at https://www.yucaipayac.com/investor-relations.
