SIGMAROC PLC

 ('SigmaRoc' or the 'Company')

Receipt of Polish Competition Office Clearance

SigmaRoc (AIM:SRC), the AIM quoted buy-and-build quarried materials group, is pleased to announce that, further to its announcement of 15 July 2021, it has received full and unconditional merger clearance from the Polish Office of Competition and Consumer Protection (UOKiK) in respect of SigmaRoc's acquisition of the entire issued capital of Nordkalk Oy Ab (the "Acquisition"), a wholly-owned subsidiary of Rettig Group Oy Ab.

Furthermore, the Company received shareholder approval for the Acquisition at its general meeting held on 2 August 2021. Accordingly, the Company can now proceed with completion of the Acquisition.

The Acquisition consideration of approximately €470 million is being satisfied through a combination of €270 million from the proceeds of the Placing, the drawdown of €150 million of the New Facility, and the issue of the €50 million Consideration Shares. The Company is currently undertaking the steps to draw-down under the New Facility so that it is in a position to complete.

It is expected that application will be made to the London Stock Exchange plc for the admission of the 305,882,352 Placing Shares, 50,276,521 Consideration Shares and 1,880,301 Retail Offer Shares to trading on AIM ("Admission") shortly.

Completion of the Acquisition will occur on Admission, which the Company currently expects to occur on 31 August 2021. A further announcement will be made in due course once application for Admission has been made and the date of Admission is finalised.

Max Vermorken, CEO of SigmaRoc plc, commented:

"We are delighted with this swift decision from the Polish competition authority and look forward to working with our new colleagues at Nordkalk to generate value for our shareholders."
