PSI Software SE Delays 2025 Financial Statement Release Amid Warburg Pincus Deal

Berlin, Germany – March 18, 2026 – PSI Software SE announced today that it is postponing the release of its complete and audited 2025 annual and consolidated financial statements, originally scheduled for March 31, 2026. The delay is attributed to the final assessment of accounting facts related to the investment agreement with Warburg Pincus, signed in October 2025.

Investment Agreement and Takeover Offer

In October 2025, PSI Software SE entered into an investment agreement with Zest BidCo GmbH, a holding company indirectly controlled by funds managed by Warburg Pincus LLC . Warburg Pincus subsequently launched a voluntary public takeover offer for all outstanding shares of PSI at a price of EUR 45.00 per share in cash, representing an 84% premium to the undisturbed closing share price as of October 8, 2025, and a 63% premium to the three-month volume-weighted average share price.

As of the agreement, Warburg Pincus secured approximately 28.5% of PSI’s total share capital from anchor shareholders, with E.ON retaining its 17.77% shareholding as a strategic investor . The offer price implied an equity valuation for PSI of approximately EUR 702 million .

Financial Performance in 2025

Despite the pending financial statement release, PSI reported positive performance indicators for 2025. Recent orders increased by 25% year-over-year to 322 million euros, compared to 257 million euros in 2024. The company confirms its targets for 2025, anticipating approximately 10% revenue growth and an adjusted EBIT margin of 4%.

Revised Financial Statement Release Date

The 2025 annual and consolidated financial statements are now scheduled to be published within the statutory four-month period following the end of the financial year, meaning publication is expected by the end of April 2026.
