Summa Defence Plc has signed an agreement to divest its subsidiary, a renewable energy specialist Rasol Oy, to Rasol's current management. The divestment is part of Summa Defence's strategic review and evaluation of strategic alternatives for some of its subsidiaries, announced on 15 May 2026. The subsidiaries within the scope of the strategic review are IntLog Oy, Lightspace Group Inc, including its subsidiaries, as well as Aquamec Oy and Rasol Oy.

Rasol is a Finnish renewable energy expert that supplies and installs high-quality solar power systems, battery packs and air-source heat pumps for buildings, properties and registered entities in Germany, Denmark and France. In 2025, Rasol's net sales amounted to EUR 2.7 million (EUR 3.1 million in 2024), and the company's EBIT was EUR -0.2 million (EUR -0.2 million in 2024). The company employs approximately 15 persons. All employees will transfer to the buyer as part of the transaction.

"The divestment of Rasol is the first step in the strategic review and evaluation of strategic alternatives for some of our subsidiaries. The objective of this review is to support Summa Defence's long-term strategy, strengthen our capital structure and accelerate growth in our core businesses in the defence sector," says Robert Blumberg, CEO of Summa Defence.

The selling price of Rasol is EUR 5,000. Any debts owed by Summa Defence Plc or its subsidiaries to Rasol, and vice versa, will be settled in connection with the transaction.

As a result of the transaction, Summa Defence will recognise an impairment of approximately EUR 2.0 million in its full-year 2025 results. After the impairment, the carrying amount of the Group's goodwill is approximately EUR 167 million. The transaction was closed today.

The review and evaluation of strategic alternatives regarding the other subsidiaries is ongoing. The evaluation is part of Summa Defence's normal strategic development work and may not necessarily result in any arrangements or transactions.
