Proximus Group has announced that chief financial officer Mark Reid will leave the company at the end of January 2026 to pursue other career opportunities in the UK.
Reid joined Proximus in May 2021, having previously held senior finance roles at British Airways, Travelport, Yahoo and Liberty Global, and worked in Switzerland, the UK and the United States.
The operator said Reid played a key role in delivering its #inspire2022 plan, helping return domestic operations to top-line and EBITDA growth from 2022. Under its #bold2025 strategy, Proximus credited Reid and his team with maintaining “consistently strong” financial performance amid increased market competition and higher investment needs linked to Belgium’s gigabit network rollout.
Proximus also said Reid led a rigorous M&A programme, culminating in a domestic divestment plan of around €500 million by the end of 2025. Following the creation of Proximus Global at the start of 2025, Reid additionally served as Proximus Global CEO ad interim between April and November.
To support the transition, Nicolas Gaertner, currently deputy CFO, will assume the CFO role on an interim basis from 15 January, with a permanent appointment to be announced in due course.
Proximus management thanked Reid for his contribution to the group’s financial performance and for overseeing a domestic divestment programme during a major fibre capex cycle.
