Chief Financial Officer Transition

Gooch & Housego plc (AIM: GHH), the specialist manufacturer of photonic components and systems, announces that Chris Jewell, Chief Financial Officer, has informed the Board of his intention to step down from his role. Chris will leave the Board, and the Company, on 30 September 2025, the conclusion of the current financial year.

The Company has appointed Martin Hopcroft as Interim CFO, effective from 28 July 2025 to enable a handover period. Martin is a seasoned finance leader with significant experience supporting listed companies through transition periods. He will take executive responsibility for the finance function while the Board continues its search, in partnership with Korn Ferry, for a permanent CFO.

Chris joined G&H in 2019 and has made a substantial contribution to the Company's development over the past six years. He has supported the business through operational and strategic changes, including the recent acquisition of Global Photonics and has strengthened financial systems and controls across an increasingly international footprint.

The Group is due to release its results for the current financial year in December 2025. As stated in our recent interim results announcement on 3 June 2025: "Our order book remains at a healthy and growing level and we have over 95% cover needed to support expected FY2025 revenue. At the same time, we have entered a period of unprecedented global macroeconomic uncertainty and fluidity which has increased near-term risk. The Group is proactively managing this increased complexity and uncertainty in the global supply chain since the imposition of the new and constantly changing US tariff regime and the associated counter measures from other countries. G&H is also involved in advanced hi-tech development and production programmes some of which are dependent upon inputs from our customers, regulators and suppliers in order to progress to their expected timescales."

Further announcements will be made as appropriate.

Charlie Peppiatt, Chief Executive Officer of Gooch & Housego, said:

"Chris has brought professionalism, integrity and a steady focus throughout his time at G&H. I've valued his counsel since joining as CEO and would like to thank him for the support he has given me, the leadership team and the broader business. I wish him every success for the future."

Gary Bullard, Chair of Gooch & Housego, added:

"Chris has played a central role in G&H's evolution over many years and leaves the Company in a stronger position for the next stage of its growth. On behalf of the Board, I'd like to express our gratitude for his dedication and service. We are pleased to welcome Martin Hopcroft as Interim CFO."
