Benchmark Holdings plc

("Benchmark", the "Company" or the "Group")

Conditions for completion of private placement and Norwegian retail offering fulfilled and registration of new share capital

Reference is made to the stock exchange announcement dated 6 December 2022 regarding the successful placement of 35,189,350 new shares in the Company, raising gross proceeds of approximately NOK 158 million (the "Private Placement" and the "Norwegian Retail Offering") and the stock exchange announcement dated 13 December 2022 confirming that sufficient shares have been moved from UK CREST to VPS or have been placed with free float qualifying investors in VPS pursuant to the Private Placement and the Norwegian Retail Offering, to meet the conditions for admission to trading on Euronext Growth Oslo.

The Company hereby announces that 35,189,350 new shares have been issued by the Company and admitted to trading on the AIM market of the London Stock Exchange, thereby fulfilling the remaining condition for completion of the Private Placement and the Norwegian Retail Offering.

Trond Williksen, Chief Executive of Benchmark commented:

"We are pleased to have successfully completed our Private Placement and the Norwegian Retail Offering, to commence our dual listing on AIM and Euronext Growth Oslo. The funds raised both fulfil the free float Admission requirements for the latter, whilst also providing additional resources to underpin the positive momentum we are seeing in the business. I welcome our new Norwegian shareholders and look forward to reporting further progress in 2023."

The share capital of the Company following the issue is GBP 739,153.148 divided into 739,153,148 validly and legally issued and fully paid up ordinary shares, each with a par value of GBP 0.001. The total number of voting rights in the Company as of 14 December 2022 is therefore 739,153,148 and this figure may be used by shareholders as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change in their interest in, the Company under the UK Financial Conduct Authority's Disclosure Guidance and Transparency Rules.

The Private Placement will be settled by the Managers (as defined below) on a delivery-versus-payment basis on or about 15 December 2022. The delivery-versus-payment settlement in the Private Placement is facilitated by a pre-funding agreement entered into between the Company and the Managers and a share lending agreement (the "Share Lending Agreement") entered into between the Company, the Managers and Ferd AS ("Ferd"). The payment date in the Norwegian Retail Offering is 14 December 2022, and the offer shares will be delivered to the VPS accounts of subscribers in the Retail Offering who have paid on or about 15 December 2022. Allocated shares in the Private Placement and the Retail Offering shall not be tradeable until the first day of Admission and timely payment.

The Company's shares are expected to commence trading on Euronext Growth Oslo on or about 15 December 2022.

Please refer to the forms attached, in accordance with MAR article 19, for information regarding the allocation of shares to Ferd and the redelivery of the shares lent by Ferd to the Managers as part of the share lending agreement.
