Horizon Discovery Group plc provided earnings guidance for the six months ended June 30, 2018 and full year 2018. For the period, the group expects to report revenues of approximately £25.1 million (H1 2017: £12.1 million), £27.3 million on a constant currency basis, in line with Board expectations. This represents growth of 107% against the equivalent prior period, 126% on a constant currency basis. Revenues on a like-for-like basis (pre-acquisition of Dharmacon) are expected to be approximately £11.1 million (H1 2017: 12.1 million), £12.0 million on a constant currency basis. Reported gross margins are expected to exceed 60% (H1 2017: 64%), representing three consecutive interim periods of gross margins in excess of 60%. The Group expects to report negative EBITDA before exceptional items in first half 2018 due to the phasing and mix of revenue, which is anticipated to be exceeded by positive EBITDA in second half 2018. The Group expects to report positive EBITDA for fiscal year 2018 before exceptional items below the current range of analysts' expectations.
