Oed (Austria), 30 September 2026 – ASTA Energy Solutions AG (ISIN AT100ASTA001, “ASTA” or the “Company”) has been informed by its major shareholder ETV Montana Tech Holding GmbH (the “Selling Shareholder”) that it has successfully completed the placement of in aggregate 500,000 shares in the Company. The placement price was set at EUR 60.00 per share. The shares were placed with a broad base of international institutional investors. Settlement is expected to take place on 2 October 2026. Makra GmbH did not sell any of its shares in the placement.

As announced, the Selling Shareholder intends to use the proceeds from the placement partly to satisfy the contractual earn-out obligation payable to Montana Aerospace AG. Following completion, ETV Montana Tech Holding GmbH and Makra GmbH hold in aggregate approx. 51.2% of the Company's share capital and remain its majority shareholders. The free float has increased to approx. 42.9%. Both ETV Montana Tech Holding GmbH and Makra GmbH have agreed to a lock-up period of 180 days following settlement, subject to customary exceptions.

DDr. Michael Tojner, majority shareholder of ASTA Energy Solutions AG:
“ASTA is exceptionally well positioned to benefit from the structural growth opportunities driven by the global energy transition and increasing electricity demand worldwide. The transaction allows us to partially fund the announced contractual earn-out obligation related to the acquisition of ASTA while simultaneously increasing the Company's free float and enhancing trading liquidity in the stock. We remain firmly committed to ASTA's long-term success and will continue to support the Company's development as majority shareholder.”

 Dr. Karl Schäcke, CEO of ASTA Energy Solutions AG:
“We welcome the broader shareholder base and the increased liquidity of our shares. A larger free float further enhances ASTA's visibility and attractiveness for institutional investors. Following our recent guidance upgrade, we reaffirm our outlook and remain confident in ASTA's continued growth and earnings development, supported by strong customer demand, a robust order backlog and the structural growth opportunities created by the global energy transition.”

Berenberg acted as Sole Global Coordinator and Sole Bookrunner for the Placement.
