PSI Software Enters Strategic Partnership with Warburg Pincus

PSI Software SE has entered into an investment agreement with Warburg Pincus for a strategic partnership, announcing a public takeover offer. On October 12, 2025, PSI and Zest BidCo GmbH, a Warburg Pincus-controlled entity, signed the agreement to foster PSI's long-term growth.

Warburg Pincus plans a voluntary public takeover offer of €45.00 per PSI share. Anchor shareholders representing 28.5% of PSI's share capital have initiated agreements, with partial reinvestment from one shareholder with Warburg Pincus.

E.ON Verwaltungs GmbH, PSI's second-largest shareholder, agrees to retain its 17.77% stake, entering a non-tender and framework agreement. The PSI Management and Supervisory Boards support the offer, pending offer document review.

The agreement maintains PSI's growth strategy, management, and Berlin headquarters, with no domination agreement for two years post-offer closing, expected in H1 2026.
