Post-Close Trading Update

Senior plc ("Senior" or the "Group"), an international manufacturer of high technology components and systems, today issues this trading update for the year ended 31 December 2025 (the "Period") for the Group's continuing operations.

Strong performance ahead of expectations

Following the November trading update we have seen stronger than expected trading, notably in Aerospace, such that we now expect full year adjusted profit before tax(1) to be comfortably above previous expectations.

Since the trading update, we have taken action and reduced our cost base in certain Flexonics operations. The related restructuring costs are treated as adjusting items and will be announced at our full year results.

As a result, the Board anticipates full year 2025 Group performance to be comfortably above previous expectations. While it is still early in the year, trading in January 2026 has started well.

Strengthened balance sheet

The initial cash proceeds from the sale of the Aerostructures business along with strong cash generation has supported deleveraging, with net debt anticipated to be below £80m (pre- IFRS 16) at the end of FY25 (FY24: £153m). FY25 leverage is expected to be below 1.0x net debt to EBITDA (pre- IFRS 16) down from 1.8x at the end of 2024.

In addition, the Group completed a Buy-In transaction on its UK defined benefit pension scheme in FY25 which has de-risked the balance sheet.

The Group will publish its full year results for the year ended 31 December on 2 March 2026.
