FY 2025 Trading Update

Tan Delta (AIM:TAND), a leading provider of intelligent monitoring and maintenance systems for commercial and industrial equipment is pleased to provide a post year end trading update.

The Board of Tan Delta is pleased to report that unaudited revenue for the year ended 31 December 2025 ("FY 2025") is expected to be approximately £1.2m, 20% ahead of management expectations as announced in the Interim Results on 30 September 2025. Unaudited cash as at 31 December 2025 was approximately £1.5m with no debt. As is customary, all figures are subject to final year end audit.

During the year, the Company continued to execute on its business plan to bring real time oil condition monitoring to industrial and commercial companies operating rotating equipment that relies upon oil for reliable operation. This has and continues to entail Tan Delta engaging in managed trials and small deployments across a broad cross section of customers ranging from large multi-nationals with extensive equipment estates to smaller localised users. The FY 2026 pipeline of interest for Tan Delta's solutions remains strong and further updates will be provided in due course.

Chris Greenwood, CEO said: "Our proprietary Full Spectrum Holistic ("FSH™") real time oil analysis technology endows our solutions with exceptional ability to provide equipment operators with real time insight and knowledge on the health and maintenance status of their operating equipment, enabling them to make effective and efficient data driven maintenance decisions. For that reason, we continue to have considerable and growing market interest in our differentiated offer and are working through the typically lengthy industrial and commercial validation trials and processes with multiple prospective customers moving towards wider adoption and rollouts."
