Director Retirement and Board Change

Big Technologies plc (AIM: BIG), a leading provider of electronic monitoring solutions, today announces the retirement of Ian Johnson from the Board and the appointment of Charles Lewinton as Acting CEO.

Ian Johnson joined the Board of Big Technologies in April 2025, during a challenging time for the Group. Ian was appointed CEO in May 2025, tasked to transition the business while providing stability and strong leadership and experience at a critical period. Ian oversaw the restructure and professionalisation of the business, strengthening the management of the Group and establishing a foundation for a return to growth. Under Ian's leadership, new business momentum has increased, as demonstrated by 12% ARR growth in fiscal year 2025.

Ian oversaw the creation of a robust succession plan across the Group, including for the post of CEO. In line with this succession plan, the Board is pleased to announce that Charles Lewinton will assume the role of Acting CEO whilst a formal search process is conducted for a permanent successor. Charles will be included in the formal search process for the permanent appointment.

Charles has extensive experience with the Group's clients, products and employees having joined the business pre-IPO, fourteen years ago. Charles has served as Chief Operating Officer, Chief Technology Officer and VP Americas during his time with the Group, demonstrating his broad leadership qualities. Charles has most recently overseen significant growth in the Americas, with US ARR growth at 40% in 2025, and supplemented by this year's large contract win in Chile. He has also overseen the release and certification of the Group's latest AlcoTag and AlcoBreath products.

Ian's responsibilities as Chief Executive Officer will now transfer to Charles, with Ian remaining with the business until the end of July to provide on-going handover support.

Sangita Shah, Interim Chair, said:

"I would like to express my gratitude to Ian for his work in providing stability and leadership to the business during a turbulent period. Ian has achieved what he set out to do and more: a restructured business yielding growth whilst maintaining resilience at a challenging time. The management of the Group has been strengthened and repivoted, driving performance through accountability and performance management.

I am delighted that Charles will assume the role of Acting CEO whilst a formal search process is conducted. Charles is tireless in his commitment to driving the business forward and has an extraordinary breadth of knowledge and experience with the Group's activities. Charles has also demonstrated his calibre during the turbulent period for the Group in early 2025, ensuring the Group's operations continued seamlessly.

I look forward to working with Charles more closely to build on the good work that he and Ian have overseen since the middle of 2025."

Ian Johnson, CEO, said:

"I am delighted to see Charles step up to the Acting CEO position. Charles and I have worked closely since I joined the Board in April 2025, and he is exceptionally well suited to assume these responsibilities.

I am proud of our achievements over the past year, not least returning the business to growth and increasing contract momentum. Big Technologies and Buddi is a fantastic business with great prospects ahead. I wish the team well and look forward to watching the Group go from strength to strength."
