About Horizon Discovery Group plc

Horizon (LSE: HZD) is a revenue-generating life science company supplying research tools to organisations engaged in genomics research and the development of personalised medicines. Horizon has a diverse and international customer base approaching 800 organisations, including major pharmaceutical, biotechnology and diagnostic companies as well as leading academic research centers. The Company supplies its products and services into multiple markets, estimated to total in excess of £29 billion by 2015.

Horizon’s core capabilities are built around its proprietary translational genomics platform, GENESIS™, a high-precision and flexible suite of gene editing tools able to alter almost any endogenous gene sequence of human or mammalian cell-lines. Horizon has applied GENESIS™ to create over 550 X-MAN™ cell lines, accurately modeling the disease-causing mutations found in genetically based diseases. These ‘patients-in-a-test-tube’ are being used by customers to identify the effect of individual or compound genetic mutations on drug activity, patient responsiveness, and resistance, which may lead to the successful prediction of which patient sub-groups will respond to currently available and future drug treatments.

In addition, Horizon provides GENASSIST™ CRISPR and rAAV gene editing tools, custom cell line generation services for research and bioproduction applications, quantitative molecular reference standards, contract research and custom screening services, haploid cell lines (through Horizon’s partner Haplogen), and custom shRNA development services and off-the-shelf validated shRNA (through Horizon’s partner Sirion).

Horizon is headquartered in Cambridge, UK, and is listed on the London Stock Exchange’s AIM market under the ticker “HZD”, for further information please visit: www.horizondiscovery.com
