Sound Energy plc

("Sound Energy" or the "Company")

Inclusion in FTSE AIM UK 50 Index and Migration to SETS Trading Platform

Sound Energy, the European and African focused upstream company, is pleased to announce that, following Sound Energy's inclusion in the FTSE AIM UK 50 Index with effect from Monday 19 September 2016, trading of the Company's ordinary shares will be migrated to the London Stock Exchange's SETS trading platform with effect from that same date. The Company's ordinary shares have historically been traded via the London Stock Exchange's SEAQ trading platform.

SETS is the London Stock Exchange's premier electronic trading service that combines electronic order-driven trading with integrated market maker liquidity provision. SETS is used by all FTSE100 constituents and provides access to electronic order-driven trading, as opposed to the solely market maker driven SEAQ system.

The Company also announces that an updated investor presentation is now available from the Company's website at www.soundenergyplc.com
