Circassia Pharmaceuticals plc

Block Listing Application

Circassia Pharmaceuticals plc ("Circassia" or "the Company") today announces that an application (the "Application") has been made to the UK Listing Authority and the London Stock Exchange for a block listing of 400,000 ordinary shares of 0.08 pence each in the Company ("Ordinary Shares") to be admitted to trading on the Premium Segment of the London Stock Exchange.

The Application relates to Ordinary Shares to be issued from time to time in order to satisfy the potential exercise of share options granted under the 2015 Performance Share Plan Scheme.

It is expected that admission will become effective on 21 May 2018. When issued, the Ordinary Shares will rank pari passu with the existing ordinary shares of the Company.

As at today, there are 333,466,262 ordinary shares in issue with one voting right per share. The Company does not hold any shares in treasury. The Company will notify on a monthly basis when there are changes to the issued share capital of the Company, and these monthly figures may be used by shareholders as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
