Senior plc: Ten-month Trading Update

Senior plc ("Senior" or the "Group"), an international manufacturer of high technology components and systems, today issues this trading update for the ten-month period ended October 2025 (the "Period") for the Group's continuing operations.

Healthy trading in the Period, full year performance anticipated to be comfortably above the Board's previous expectations

Continuing Group Trading Update & Full Year Outlook

Senior delivered a strong trading performance in the Period.  Group revenue increased by 5.9% year-on-year on a constant currency basis, with Aerospace sales increasing 9.4% and Flexonics growing by 1.5%.

Aerospace growth is being driven by increasing production rates of commercial aircraft, higher defence spending and improved pricing, which we expect to continue for the full year and beyond.  In Flexonics, aftermarket demand for our nuclear and downstream oil & gas products remains robust, and we have continued to outperform land vehicle markets, which have softened in the second half of the year as anticipated and are predicted to remain soft in 2026.  Based on Flexonics Division trading in the Period, we now expect Flexonics 2025 performance to be slightly better than 2024.

With the continuing strong performance in Aerospace, and improved trading in Flexonics, the Board anticipates overall Group performance for the full year to be comfortably ahead of previous expectations.  The Group is executing on its strategy effectively and we are on track to deliver our medium-term financial targets.

Aerostructures Trading (Discontinued Operations)

The sale of our Aerostructure business is progressing well and we are still aiming to complete by the end of 2025.  We were pleased to see the extended US Government shutdown ending, as that had delayed regulatory approval progress.

Aerostructures trading performance in the Period continued to improve on a year-on-year basis.  We remain fully committed to delivering the maximum possible value to shareholders under the earn-out structure, which is tied to 2025 EBITDA performance.  Whilst we continue to make progress, certain external supply-chain disruptions are impacting deliveries.  We are diligently working with suppliers and customers to mitigate the impact and position the business to optimise the earn-out outcome.

Full year results

Senior will present its full year results announcement for the year ending 31 December 2025 on Monday, 2 March 2026.

Notes

The Group's principal foreign exchange translation exposure is to the US Dollar.  Our current assumption is that the average US Dollar to Pound Sterling exchange rate for the full-year 2025 is $1.31.

EBITDA, in the context of the performance of Aerostructures, is defined as adjusted profit before tax and before interest, depreciation, amortisation and profit or loss on sale of property, plant and equipment.
