Dear Sirs

We were previously the statutory auditors for Verona Pharma plc and, on 11 May 2015, we reported on the consolidated financial statements of Verona Pharma plc as of and for the year ended 31 December 2014. At Verona Pharma plc’s Annual General Meeting of shareholders on 11 June 2015, we did not offer ourselves for re-election as Verona Pharma plc’s statutory auditors and were therefore not reappointed as auditors of the company. We have read Verona Pharma plc’s statements included under the heading “Auditors” in its Form F-1 dated November 23, 2016, and we agree with such statements.

Yours faithfully,

/s/ UHY Hacker Young
