GRK Infra Plc Stock Exchange Release 30 June 2026 at 09.44 a.m. EEST

GRK Infra Plc ("GRK") announced on 18 May 2026 that it had signed a share purchase agreement to acquire Keski-Suomen Betonirakenne Oy ("KSBR") and its subsidiaries from its current shareholders (the "Sellers") (the "Transaction"). GRK has today completed the Transaction.

"This acquisition is a strategically important step for GRK and supports the company's established growth strategy across several areas. Its key objective is to realise synergies between GRK's and KSBR's business operations and to strengthen GRK's position in private sector projects. Combining the two companies' capabilities improves GRK's ability to carry out large industrial and energy sector projects on a broader scale than before. The acquisition also strengthens GRK's operational capabilities, particularly in technically demanding projects, and deepens GRK's competency in concrete construction. This is a natural complement to the company's existing service offering and supports the objective of being a versatile infrastructure builder across the full project lifecycle," says GRK's CEO Mika Mäenpää.

"From a customer perspective, KSBR's strong position in the private sector supports GRK's objective of growing private sector sales and balancing the business portfolio. At the same time, this acquisition reduces dependence on public sector procurement cycles and supports a more resilient revenue stream," Mika Mäenpää continues.

Directed share issue to the Sellers

In accordance with the terms and conditions of the Transaction, part of the purchase price is paid in new shares in GRK agreed to be valued at EUR 16 per share. GRK's Board of Directors has today resolved on a directed share issue to the Sellers (the "Directed Share Issue"). GRK's Board of Directors has resolved on the Directed Share Issue pursuant to the authorisation granted by GRK's Annual General Meeting held on 30 March 2026.

GRK issues in the Directed Share Issue a total of 1,676,273 new shares (the "Consideration Shares"), representing approximately 4.09 per cent of all shares in GRK prior to the Directed Share Issue and approximately 3.93 per cent of all shares in GRK following the Directed Share Issue. The total number of all shares in GRK following the Directed Share Issue will be 42,645,504 shares. The subscription price will be recognised in GRK's reserve for invested unrestricted equity.

The Consideration Shares are expected to be registered in the Trade Register on or about 2 July 2026, and GRK intends to apply for the admission of the Consideration Shares to trading on the regulated market maintained by Nasdaq Helsinki Ltd. Trading in the Consideration Shares on Nasdaq Helsinki is expected to commence on or about 3 July 2026, subject to the approval of the listing application.

The Sellers have agreed to a transfer restriction concerning the Consideration Shares prohibiting the disposal of the Consideration Shares by the Sellers. The majority of the Sellers have agreed to be subject to a transfer restriction of thirty-six (36) months from the completion of the Transaction in respect of in aggregate 1,456,751 Consideration Shares. However, certain Sellers, who will subscribe for in aggregate 219,522 Consideration Shares, shall have 25 per cent of their Consideration Shares released from the transfer restriction at each of twelve (12), eighteen (18), twenty-four (24) and thirty (30) months from the completion of the Transaction.
