OTAQ, the marine technology products and solutions group for the global aquaculture and offshore oil and gas industries, received notification on 17 January 2022 from Cytec Solutions Corporate Trustees Limited (the "SIP Trustee") in relation to the issue and allotment of 9,330 ordinary shares of 15 pence each in the Company ("Ordinary Shares") for the benefit of participants of the OTAQ Share Incentive Plan (the "SIP"), including those Persons Discharging Managerial Responsibilities of the Company (each, a "PDMR") outlined below in accordance with the rules of the SIP (the "SIP Award").

The SIP is an all-employee trust arrangement approved by HM Revenue and Customs, under which each participating employee will acquire Ordinary Shares at the prevailing market price per share using contributions deducted from pre-tax salary in each calendar month ("Partnership Shares"), with each participating employee being awarded one Ordinary Share for each Partnership Share ("Matching Shares"), using newly issued shares.

Details of the number of Partnership Shares purchased by the PDMRs at a price of 26 pence per Ordinary Share, and the number of Matching Shares allocated by the SIP Trustee to the PDMRs for no consideration, are set out against their names in the table below.

The SIP Award has been satisfied by the issue of 9,330 new Ordinary Shares (the "SIP Shares") to the SIP Trustee. The SIP Shares shall rank pari passu in all respects with the Company's existing ordinary shares in issue. Applications have been made to the FCA and to the London Stock Exchange for the SIP Shares to be admitted to the Standard segment of the Official List of the FCA and to trading on the London Stock Exchange's Main Market for listed securities respectively ("Admission"). It is expected that Admission will become effective on or around 8.00 am on 21 January 2022.

Total Voting Rights

Following Admission, the enlarged issued share capital of the Company will comprise 37,698,502 Ordinary Shares, with voting rights. The Company does not hold any Ordinary Shares in treasury. Therefore, the total number of Ordinary Shares in the Company with voting rights will be 37,698,502.

The aforementioned figure may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
