Benchmark Holdings plc

("Benchmark" or the "Company")

Successful private placement and retail offering ahead of admission on Euronext Growth Oslo

Reference is made to the stock exchange announcements by the Company on 30 November, 1 December and 6 December 2022 regarding Benchmark's contemplated private placement of new shares (the "Private Placement") and the contemplated retail offering of new shares (the "Norwegian Retail Offering") in the Company.

The Company is pleased to announce that it has allocated 35,189,350 new shares under the Private Placement and the Norwegian Retail Offering at a subscription price of NOK 4.50 each, raising gross proceeds of approximately NOK 158 million (equivalent to approximately GBP 13 million) and further that Benchmark is expected to complete the admission of its shares on Euronext Growth Oslo ("Admission") on or about 15 December 2022 (subject to fulfilment of the conditions for Admission).

The purpose of the Private Placement and the Norwegian Retail Offering is to fulfil the free float Admission requirements and the net proceeds will be used for general corporate purposes. Benchmark's application for Admission was approved by Oslo Børs on 5 December 2022, conditional upon fulfilment of 10% spread of share ownership and minimum NOK 300 million free float in Euronext Securities Oslo (the "VPS"). The Company expects to fulfil these conditions taking into account, in aggregate, the shares issued in connection with the Private Placement, the Norwegian Retail Offering, and the undertakings of certain existing shareholders to move across part or all of their shares in the Company from UK CREST to VPS. The Private Placement and the Norwegian Retail Offering will not be completed until a sufficient number of existing shares have been registered in the VPS. In the event of a delay or failure by existing shareholders to move their shares to the VPS, the settlement of the Private Placement and the Norwegian Retail Offering, and hence the Admission, may be delayed, or ultimately cancelled.

Notification of allocation in the Private Placement and in the Norwegian Retail Offering, including settlement instructions, will be sent to investors on or about 7 December 2022. The Private Placement will be settled by the Managers 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. Investors in the Private Placement and Retail Offering having access to investor services through their VPS manager, will be able to check the number of offer shares allocated to them from 10:00 CET on 7 December 2022. The Managers may also be contacted for information regarding allocations.

Completion of the Private Placement and the Norwegian Retail Offering is conditional upon (i) the Company's satisfaction of the conditions for Admission, including a 10% free float requirement in the VPS; (ii) issuance of the New Shares (as defined below) being validly made; and (iii) payment being received for, and the New Shares being validly issued and the shares transferred from Ferd to the Managers pursuant to the Share Lending Agreement being registered in applicable registers including the VPS.

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 reserves the right (until the issue of the New Shares) at any time and for any reason, to cancel, and/or modify the terms of, the Private Placement. Neither the Company nor the Managers will be liable for any losses incurred by applicants if the Private Placement is cancelled, irrespective of the reason for such cancellation.

The shares of the Company are enabled for settlement in the UK CREST system to facilitate existing trading on the AIM Market of the London Stock Exchange ("AIM"). In order to facilitate a secondary registration of shares in the VPS, the Company will utilise a CSD-link to allow for the shares in the Company to be traded on Euronext Growth Oslo. The shares to be delivered in the Private Placement and the Retail Offering will be registered in the VPS to enable trading on Euronext Growth Oslo, in addition to a number of existing shares which are expected to be transferred from CREST to VPS. In connection with the Admission, it is anticipated that approximately 80% of the Company's shares will be registered in the VPS and tradable on Euronext Growth Oslo in due course (incl. the shares delivered pursuant to the Private Placement, the Retail Offering and the transfer of certain existing shares from UK CREST to VPS by certain existing shareholders of the Company, including the majority shareholders Ferd, Kverva Finans AS and JNE Partners LLP), although this percentage may fluctuate from time to time as shareholders may choose to transfer their shareholdings between CREST or VPS.

Related Party Transaction

The Company has entered into the Share Lending Agreement, pursuant to which Ferd has committed to lend to the Managers up to 35,189,350 existing shares in the Company in order to facilitate timely settlement to the investors in the Private Placement and the Retail Offering. Ferd is a substantial shareholder of the Company (within the meaning of the AIM Rules). In accordance with the Share Lending Agreement and pre-funding agreement referred to above, the Managers have agreed to subscribe for 35,189,350 new shares at NOK 4.50 per share ("New Shares"), on behalf of the investors being allocated shares in the Private Placement and the Retail Offering, and direct that such New Shares are issued to Ferd to satisfy their obligation to re-deliver the 35,189,350 borrowed shares.

Ferd has, subject to the conditions for completion, agreed to subscribe for 6,549,358 shares pursuant to the Private Placement.

The Share Lending Agreement, when aggregated with the participation of Ferd in the Private Placement and the participation of Ferd in the Company's green bond issue, as announced on 16 September 2022, constitutes a related party transaction under the AIM Rules. The independent Directors (being all Directors of the Company other than Kristian Eikre, who is co-head of Ferd Capital) consider, having consulted with Numis, the Company's nominated adviser, that the terms of the related party transaction are fair and reasonable in so far as the shareholders of the Company are concerned.

In addition, Kverva Finans AS, JNE Partners LLP and Laura Lavers (who has been appointed as a Director conditional on the Euronext Growth Admission) have, subject to the conditions for completion, agreed to subscribe for 7,528,906, 6,897,811 and 530,000 shares respectively pursuant to the Private Placement.

In compliance with the Company's AIM listing, an application has been made for the New Shares to be admitted to trading on AIM. It is expected that such admission will become effective on 14 December 2022 and that dealings for normal settlement in the New Shares will commence on AIM at 8.00 a.m. on 14 December 2022. The New Shares will, when issued and fully paid, rank pari passu in all respects with the shares in issue at that time, including the right to receive all dividends and other distributions declared, made or paid after the date of Admission. Please note that the New Shares and existing shares will, subject to completion be admitted to trading on Euronext Growth Oslo.

The Company's share capital following completion of the issue of the New Shares will be GBP 739,153.148 divided into 739,153,148 shares, each with a nominal value of GBP 0.001.

DNB Markets, a part of DNB Bank ASA and Pareto Securities AS are acting as joint global coordinators and joint bookrunners, managers and receiving agents (together the "Managers") in the Private Placement and the Retail Offering. Advokatfirmaet Wiersholm AS and Travers Smith LLP are acting as legal counsels to the Company, while Advokatfirmaet BAHR AS are acting as legal counsels to the Managers.
