Notice of results and revised trading update

Horsham, UK: Ceres Power Holdings plc (CWR.L) a leading developer of clean energy technology, will announce its results for the year ended 31 December 2024 on 21 March 2025. The Company also provides a further post period-end trading update.

At its interims on 27 September 2024, the Company guided to full year revenues in the range of £50-60 million. This guidance range was refined to £55-60 million with a gross margin of 78-80% when the Company reported its trading update for the year to 31 December 2024 on 29 January 2025.

As we finalise the audit, there is some uncertainty over whether a single £5 million contracted milestone payment should be recognised in 2024 or whether it is more appropriate to recognise it in 2025. This recognition date does not impact the total revenue recognised under the contract or the cash position of the company. To remove any uncertainty, and whilst the Company is working to clarify the correct accounting treatment under IFRS 15, Ceres is reverting to the original revenue guidance of £50-60 million and confirms that its gross margin will be over 75% for the year.

The management team will be hosting a live webcast for analysts and investors on 21 March 2025 at 09.30 GMT. To register your interest in participating, please go to:
