Director/PDMR Shareholding

7 March 2019

TRITAX BIG BOX REIT PLC

(the "Company")

PDMR SHAREHOLDING AMENDMENT

Further to the PDMR shareholding announcement on 18 February 2019, the Company has been notified by Richard Laing, a Non-Executive Director of the Company, that he has since been advised by the nominee company through which his wife's interests in the Company's ordinary shares (the "Ordinary Shares") are held (the "Nominee"), that Mrs Laing was allocated 12,440 Ordinary Shares by the Nominee pursuant to its participation in the Company's pre-emptive offer of Ordinary Shares which closed on Friday, 8 February 2019 (the "Open Offer").

Therefore, the total number of Ordinary Shares acquired by Mr Laing and his connected persons pursuant to the Open Offer was 12,440, not 6,733 as previously notified. The total beneficial holding of Mr Laing (and/or his connected persons) is, therefore, 45,828 Ordinary Shares, representing 0.003% of the Company's current issued share capital, rather than 40,121 Ordinary Shares. All other details remain the same.
