Share Buyback Programme

Genus (LSE: GNS; the “Group” or the “Company”), a global leader in animal genetics, announces that it is commencing a share buy-back programme (the “Programme”) pursuant to which it may repurchase up to £60 million of its ordinary shares (the “Shares”). The Programme is consistent with the Group’s capital allocation framework and reflects confidence in the Group’s financial position, long-term growth prospects and sustainable cash generation. The Programme will commence immediately and is expected to conclude during the second half of FY27.

The purpose of the Programme is to reduce the capital of an issuer. As such, Shares purchased by the Company will be cancelled.

The Programme will be carried out pursuant to a non-discretionary agreement with J.P. Morgan Securities plc (JPMS plc), under which the Company has established certain pre-set parameters in accordance with which purchases may be made during the Programme. JPMS plc shall purchase Shares as riskless principal (and not as agent of the Company). In accordance with the terms of the Programme, purchases of Shares may continue during closed periods of the Company. During any such period, JPMS plc will make its trading decisions in relation to the Shares independently of, and uninfluenced by, the Company, subject to the agreed parameters of the Programme and applicable law and regulation.

Any purchases of Shares by the Company will be carried out in accordance with (and subject to the limits prescribed by) the Company’s general authority to repurchase Shares granted by its shareholders from time to time, Chapter 9 of the Financial Conduct Authority’s UK Listing Rules and the Market Abuse Regulation (EU) No 596/2014 (as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018, as amended). The Programme will be discontinued in the event that the Company ceases to have the necessary general authority to repurchase Shares.

About Genus

Genus is a world-leading animal genetics company. Genus advances animal breeding and genetic improvement by applying biotechnology and sells added value products for livestock farming and food producers. Its technology is applicable across livestock species and is currently commercialised by Genus in the dairy, beef and pork food production sectors.

Genus's worldwide sales are made in over seventy-five countries under the trademarks 'ABS' (dairy and beef cattle) and 'PIC' (pigs) and comprise semen, embryos and breeding animals with superior genetics to those animals currently in farms. Genus's customers' animals produce offspring with greater production efficiency, and quality, and use these to supply the global dairy and meat supply chains.

The Group's competitive edge has been created from the ownership and control of proprietary lines of breeding animals, the biotechnology used to improve them and its global supply chain, technical service and sales and distribution network. The PRRS1 Resistant Pig is a market leading innovation in gene editing which Genus is looking to commercialise in the porcine industry once further regulatory approvals are obtained.

With headquarters in Basingstoke, United Kingdom, Genus companies operate in over twenty-five countries on six continents, with research laboratories located in Madison, Wisconsin, USA.
