System1 Group (AIM:SYS1), the AIM-listed marketing decision-making platform, reported full-year revenue of £37m for the year ended 31 March, broadly flat against £37.4m in the prior year, as US trade tariff uncertainty dampened client spending in the first half.
The standout number was the H2 swing: revenue in the second half ran 16% ahead of the first, with profit before tax in the period six times higher than H1, delivering a full-year outcome the company said was in line with market expectations.
Adjusted EBITDA fell to £3.7m from £6.6m a year earlier, reflecting both planned investment and macro-driven softness, while year-end net cash held near steady at £12.4m against £12.9m in FY25.
Platform revenue, which accounted for 96% of total sales, rose 3% to £35.5m, with US platform revenue up 7% and US new client revenue climbing to £3.5m from £2.8m; the client base grew to 635 from 546.
Cost efficiency actions taken in the second half removed approximately £1m in annualised costs, incurring £0.5m in restructuring charges.
"We have started FY27 with confidence," said chief executive James Gregory, citing record new business, a growing customer base and continued investment in AI-enabled capabilities.
