Half-Year Trading Update

Cerillion plc, the billing, charging and customer relationship management software solutions provider, announces an update on trading for the first six months of its current financial year ending 30 September 2026.

The dominant feature of the first half was the signing in January of Omantel as a major new client in a contract worth c. £42.5m1 over its term. As previously reported, this is Cerillion's largest win to date and another valuable reference customer. Software implementation remains on track and the contract is expected to contribute significantly in the second half of the financial year.

Like last year, the Company's full year results are expected to be strongly weighted to the second half of the financial year, with H1 revenue expected to be c. £18.0m (H1 2025: £20.9m) and H1 EBITDA c. £6.2m (H1 2025: £9.9m). This reflects the timing of contracts and the fact that, as anticipated, very little high-margin software licence revenue was recognised in H1 2026. The expected stronger performance in H2 is underpinned by the anticipated unwinding of the very strong back-order book. New orders2 have doubled to £39.6m as at 30 March 2026 (H1 2025: £19.6m), driven principally by the January win, but also by demand from existing customers. The Company's net cash at the half-year end was higher year-on-year at approximately £32.5m (31 March 2025: £31.2m).

Given progress to date, the expected income mix in the second half and anticipated new orders from existing customers, the Board believes that Cerillion remains well-positioned to meet market expectations for the financial year. In addition, the pipeline of new business opportunities remains strong, and the Company continues to invest in the business to support growth.

Interim results will be published on 1 June 2026, when a further update on current trading and prospects will be provided.
