("hVIVO" or the "Company")

Statement regarding share price

The Board of hVIVO plc (AIM: HVO) notes the sudden and extreme fall in its share price in recent days and confirms that it knows of no reason for such a fall.

The Company announced initial results on 26 March 2018 of a Phase IIb study examining FLU-v as a potential universal vaccine against influenza (flu) which, although only indicating a trend to statistical significance of the primary endpoint, did demonstrate a statistically significant reduction in overt flu symptoms and gives the Board cause for optimism that its investment in FLU-v (through its joint venture Imutex Limited) has potentially significant future value.

The Company will announce its audited preliminary results for the year ended 31 December 2017 on 19 April 2018. Financial results for the year ended 31 December 2017 are expected to be in-line with market expectations, with cash as at 31 December 2017 of £20.3 million (2016: £25.7 million) which is markedly ahead of expectations.
