NEW YORK, September 2, 2020 - Renalytix AI plc (LSE: RENX) (NASDAQ: RNLX) announces that on 28 August 2020 it granted purchase rights (the "Purchase Rights") to, amongst others, O. James Sterling, Chief Financial Officer, pursuant to the Company's 2020 Employee Share Purchase Plan (the "2020 ESPP").

The Purchase Rights are in the form of a right to acquire the Company's American Depositary Shares (each representing two ordinary shares in the capital of the Company) ("ADSs") on 27 February 2021 (the "Purchase Date") using deductions taken from salary over a six month period at a purchase price equal to 85 per cent of the lower of the closing price of the Company's ADSs on the Nasdaq Global Market on (i) 28 August 2020 (being US$14.78) and (ii) the Purchase Date. The number of ADSs acquired by O. James Sterling will be calculated on the Purchase Date and announced, together with the purchase price, thereafter.

The 2020 ESPP was approved by shareholders at the general meeting of the Company held on 13 July 2020 and details of the 2020 ESPP were set out in the circular to shareholders dated 25 June 2020. Subject to certain qualifying conditions, participation in the 2020 ESPP is open on the same terms to all of the employees of the Company's US subsidiary, Renalytix AI, Inc.

Verici update

The Company announced on 8 July 2020 that the share capital of Verici Dx has been re-designated into 59,416,134 A Shares of £0.001 each and 1 golden share of £0.001 (the "Golden Share") and that the Company would retain the Golden Share and its associated controlling voting rights. Subsequent to this announcement, the Company has entered into a declaration of trust whereby Renalytix AI plc has declared that it holds the Golden Share as nominee and on trust for Fergus Fleming, Erik Lium, James McCullough, Christopher Mills, Barbara Murphy and Chirag Parikh (the Directors of RenalytixAI) and accordingly the Company itself has no ongoing beneficial interest in Verici Dx shares. This change has been made so as to comply with EIS/VCT eligibility for Verici.
