PSI Software SE and Zest Bidco GmbH enter into delisting agreement; public delisting acquisition offer announced

Berlin, 8 September 2026 – Today, PSI Software SE (“PSI” or “Company”) (ISIN: DE000A0Z1JH9, stock exchange symbol: PSAN) and its majority shareholder Zest Bidco GmbH (“Bidder”), a holding company indirectly controlled by funds managed by Warburg Pincus LLC (together “Warburg Pincus”), entered into a delisting agreement concerning PSI.

As a result of the delisting agreement, the Bidder has announced its intention to make a public delisting acquisition offer (the “Offer”) for all outstanding shares of PSI (“PSI Shares”). The Offer will provide for a cash consideration equal to the statutory minimum price, i.e., equal to the weighted average domestic stock exchange price of the PSI Share over the past six months, and for a four-week acceptance period. It will not be subject to any conditions.

The Management Board and the Supervisory Board of PSI support the Offer and intend, subject to their review of the offer document yet to be published by Warburg Pincus as part of their fiduciary duties, to recommend the acceptance of the Offer to PSI’s shareholders. Subject to the same requirement, the Management Board will apply for the delisting of PSI Shares from trading on the regulated market of the Frankfurt Stock Exchange (Frankfurter Wertpapierbörse) before the end of the acceptance period. In addition, the Management Board will take all reasonable measures to terminate the inclusion of the PSI Shares for trading on the open market (Freiverkehr) of any other stock exchange or any other multilateral trading facility or organized trading facility, provided that the inclusion was initiated by the Company.
