INFORMATION CONTAINED IN THIS REPORT ON FORM 6-K

On 2 July 2019, Realm Therapeutics plc (“ Realm ” or the “ Company ”) (NASDAQ: RLM) announced that further to the announcement of 26 June 2019 that the Court Hearing to sanction the Scheme had been rescheduled to 8 July 2019, Realm announces an updated expected timetable of principal events.

Unless otherwise defined herein, capitalised terms and expressions used in this announcement shall have the meanings given to them in the Scheme Document.

Updated Timetable of Principal Events

The Scheme remains subject to sanction by the Court at the Court Hearing, scheduled for 8 July 2019, and the delivery of a copy of the Court Order to the Registrar of Companies. Realm expects that the Scheme will become effective (and the Acquisition will complete) on 10 July 2019, if the Court sanctions the Scheme.

Further to the announcement on 16 May 2019, the Nasdaq Hearing Panel (the “ Panel ”) has granted Realm’s additional request for a delay of any delisting action in relation to the Realm ADSs until 10 July 2019, to permit the completion of the Acquisition. Should the Acquisition fail to complete on or before 10 July 2019, the Realm ADSs may be delisted from Nasdaq. Assuming that the Scheme is sanctioned by the Court on 8 July 2019, it is expected that trading of the Realm ADSs will be suspended before the start of trading on Nasdaq on 10 July 2019. It should be noted that persons who acquire Realm ADSs after the Scheme Record Time of 6.00 p.m. (BST) on 9 July 2019 will receive New Essa Shares in settlement of their acquisition of Realm ADSs in accordance with the procedures set out in the Scheme Document and as described below.

An updated expected timetable of principal events is set out below.
