Exercise of the call option to acquire CRH's Polish Lime operations

SigmaRoc, the Northern European quoted lime and limestone group, is pleased to announce that the Group has exercised the call option, entered into on 22 November 2023 (the 'Polish Call Option'), and entered into a share purchase agreement to acquire the Polish lime operations of CRH plc (the 'Polish Target' or the 'Deal 3 Target') for a deferred consideration of €100 million (approximately £85 million). The purchase of the Deal 3 Target is conditional, inter alia, on the Polish Purchaser receiving Polish Competition Office Clearance ('PCOC'), for which the Polish Purchaser will make the necessary filings with the Polish Competition Office. Completion of the Deal 3 Acquisition is expected by the end of September 2024, subject to the PCOC.

As announced on 23 November 2023, alongside the conditional acquisition of CRH's lime businesses in Germany, Czech Republic and Ireland ('Deal 1 Targets'), the Company entered into the call options which granted it the right to acquire the UK Target ('Deal 2 Target'), as well as CRH's lime operations in Poland (the Polish Target) at a future date. Following completion of the acquisition of the Deal 1 Targets on 4 January 2024 and the completion of the acquisition of the Deal 2 Target on 27 March 2024, the Company has now exercised the Polish Call Option and entered into the Polish SPA.

The Polish Target, CRH's Ovetill Investments SP. Z o.o, includes CRH's lime and limestone flour production, associated distribution network and assets in Poland. Founded in 1910, the Polish Target has two lime production sites in Kujawy and Sitkowka.

The Company is pleased with the progress to date on the integration of the Deal 1 and Deal 2 Targets, being the German, Czech, Irish and UK entities, and will provide a further update alongside its interim results for the period ended 30 June 2024.

Defined terms used throughout this announcement have the meanings set out in the admission document published by the Company on 23 November 2023 unless the context requires otherwise.
