Financial Guidance and Path to Profit Strategy

· Based on historical H1/H2 revenue weighting (typically 40%:60%) and the current strong trading outlook, full year FY16 revenues are expected to be within a range of £24 million to £26 million. This guidance reflects:

o A reduction in molecular screening capacity as the Group consolidates the Boston facility into its new Cambridge, UKheadquarters, expected to reduce revenue by £2.7m in FY16, before returning this part of our business to growth in 2017 on a more profitable basis

· Horizon on course to report positive EBITDA in FY17 in line with the Company’s previously stated strategy:

o Path to Profit strategy includes increased business automation and reduction of senior management headcount by a third – activities on track to be complete by end December 2016

o Estimated restructuring costs of closing the Boston facility by the end of 2016 of up to £0.75 million to be recognised in the second half of 2016 that are expected to deliver run rate cost savings of at least £3.0 million from 1 January 2017

o Commitment to deliver overall Group annual cost savings of at least £5 million in 2017

Commenting on the interim results, Dr Darrin Disley, CEO of Horizon Discovery Group, said: “Horizon is making a fundamental contribution to the rapidly growing personalised and genomic medicine markets by deploying our proprietary gene editing platform to build cells and then apply them in an increasingly broad range of applications including genomics research, drug discovery and development, clinical diagnostics and drug manufacturing. Today, our core cell building platform and catalogue of over 23,000 products drives our ‘commercial fly-wheel’, an engine that generates multiple revenue streams from our cell-based assets. We are pleased to report continued revenue growth driven in particular by continued momentum in our Products business.

“Since our IPO in 2014, Horizon has made strategic investments to build an optimal business model for exploiting our technology platforms and achieve our strategic goal of becoming EBITDA positive in 2017, and sustainably profitable thereafter. We have today announced changes to the shape of our business that will allow us to focus on our core strengths, continue to scale the business on a significantly reduced cost base and drive considerable growth, integration and innovation.

“We are pleased with the progress delivered during the past six months and look forward, with confidence, to building on this in the second half of the year and beyond given the encouraging prospects for our newly shaped business. We already see signs in H2 of strong business growth and we have a clear route to profitability.”
