PRP Regulatory Progress - Canada

This announcement contains inside information

Genus (LSE: GNS), a leading global animal genetics company, announces the following update in relation to its innovative PRRS¹ Resistant Pig ("PRP") programme.  

Genus is pleased to announce that Canada has approved use of the PRP gene edit. This approval follows years of close collaboration with multiple Canadian regulatory agencies and represents another important step towards PRP commercialisation in North America. Genus believes successful commercialisation of PRP in North America requires further approvals in key North American export markets, particularly Mexico and Japan. The Group continues to make progress with regulators in these jurisdictions as well as with other international regulators, including China.

PRRS is one of the most devastating global pig diseases and causes suffering and premature death for pigs. A 2024 study from Iowa State University² estimated the cost of PRRS to be $1.2 billion per annum in the U.S. alone and a separate study indicated that PRRS increased antibiotic usage by more than 200%³.

About Genus

Genus is a world-leading animal genetics company. Genus creates advances in 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 PRP is a market leading innovation in gene editing, which Genus is looking to commercialise in the porcine industry once regulatory approval is gained.

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.
