Trading Update

System1 Group PLC (AIM: SYS1)

formerly BrainJuicer Group PLC

("System1", or "the Company", or "the Group")

Trading update for the six months to 30 September 2017

System1 (formerly BrainJuicer), the innovative marketing services group, today releases the following six month ("H1") trading update.

As announced on 18 August, trading in H1 has been slower than expected, and Gross Profit (the Company's main top line performance indicator) is 9% lower than prior year (12% in constant currency), due in the main to non-recurrence of large one-off Innovation projects as a result of some significant client spending reductions and a more competitive market. Profit Before Tax in H1 is some £0.8m (prior year: £2.8m).

We remain cautious about our prospects over the remainder of the financial year due to our usual lack of revenue visibility.

The Company will announce its interim results for the six months to 30 September 2017 on 27 October 2017.
