Porvair plc

("Porvair" or the "Group")

Block listing update

Porvair, the specialist filtration and environmental technologies group, announces that an application has been made to the Financial Conduct Authority ("FCA") and London Stock Exchange ("LSE") in order to increase an existing block listing of ordinary shares of 2 pence per share ("Ordinary Shares") used to satisfy the issue of shares pursuant to exercises of options under the Porvair plc SAYE Share Option Plan 2014 ("SAYE Plan").

Application has been made for the admission of 510,269 new Ordinary Shares to the premium listing segment of the Official List of the FCA and to trading on the main market of the LSE (together "Admission"). New Ordinary Shares issued under the block listing will rank pari passu in all respect with the existing Ordinary Shares of the Company. It is expected that Admission will become effective on 10 October 2019.

In addition, the Company currently has 21,925 new Ordinary Shares admitted (but not yet issued) under an existing block listing that relate to the Porvair Long Term Share Plan 2008 (the "LTSP"). All share issues expected to be required in order to satisfy the exercise of options under the LTSP have been made and, as a result, the associated LTSP block listing will be cancelled. The Company made 151,375 allotments under the LTSP since the last block listing return. The block listing return, as at 7 October 2019 is set out below.

The Company's issued share capital will not change as a result of the changes to the block listings set out above.

Total Voting Rights

The Company's issued share capital consists of 45,843,599 Ordinary Shares with voting rights. Therefore, the total number of voting rights in the Company will be 45,843,599. This figure may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the disclosure guidance issued by the FCA and the transparency rules made by the FCA under section 89A(1) of the Financial Services and Markets Act 2000, as amended.
