Acquisition of additional interest in Newgate Australia

Porta Communications Plc (AIM: PTCM) announces that, further to its announcement on 7 December 2016, it has increased its equity ownership in Newgate Communications PTY Ltd ("Newgate Australia") to 62.29 per cent.

Under the terms of the shareholders' agreement between Porta and its fellow shareholders of Newgate Australia (the "Australian Newgate Shareholders"), (the "Australian Shareholder Agreement"), Porta has the right to acquire an additional 4.428 per cent interest in Newgate Australia in 2017 and each of the subsequent four years. The subsequent acquisitions from the Australian Newgate Shareholders will be on a pro rata basis, or as otherwise agreed between the Australian Newgate Shareholders, and notified to Porta in accordance with the Australian Shareholder Agreement. The consideration for each additional interest acquired by Porta in Newgate Australia will be satisfied by the issue of ordinary shares of 1 pence each in the capital of the Company ("Ordinary Shares").

Consequently, Porta has acquired 4.428 per cent of Newgate Australia, increasing Porta's interest from 57.86 per cent to 62.29 per cent. The consideration for this additional interest is £277,375, which is being satisfied by the issue of 8,091,453 Ordinary Shares (the "Consideration Shares") at a price of 3.428p per Ordinary Share, being the average of the middle market quotation for each of the five business days preceding the date of issue. The Consideration Shares are subject to a lock-in agreement which provides for a six-month lock-in period and a further six-month orderly market period.

Application for admission to trading on AIM

Application has been made to the AIM market of the London Stock Exchange ("AIM") for 8,091,453 new Ordinary Shares, which rank pari passu with the Company's existing issued Ordinary Shares, to be admitted to trading on AIM. Dealings on AIM are expected to commence at 8:00 a.m. on or around 10 August 2017 ("Admission").
