The announcement, confirmed by both companies on Wednesday, means Garnier will remain at Kingfisher until a successor is appointed, with his new role as president and chief executive of the €35bn Ahold Delhaize beginning in April 2027, according to statements from both firms. He replaces outgoing Ahold Delhaize chief Frans Muller.
Kingfisher's share price rose 0.5 per cent on Wednesday's open to roughly 282p, as reported by City AM, but the stock remains down more than 10 per cent year-to-date. The muted reaction suggests the market is weighing continuity against the prospect of prolonged uncertainty.
What Garnier leaves behind at Kingfisher
Garnier joined Kingfisher in September 2019, weeks before the pandemic forced store closures and sent revenue tumbling. Over nearly seven years, he steered the group through that crisis and launched the "Powered by Kingfisher" strategy, which bundled marketplace platforms, trade-focused growth, and an AI partnership with Google Cloud.
Claudia Arney, Kingfisher's chair, said in the company's statement that Garnier had "driven many strategic innovations such as the launch of Kingfisher's marketplaces and the development of our trade business, while also executing at pace on all our priorities."
The UK operations have been the bright spot. B&Q and Screwfix both posted revenue increases in the group's most recent results, according to City AM, and are in the middle of an aggressive store expansion programme across Britain.
France is a different story. Castorama and Brico Dépôt, the group's French brands, are dragging on group revenue with falling sales. That split performance, strong domestically but weakening on the continent, defines the challenge any successor will inherit.
The 12-month handover: opportunity or drift?
A one-year notice period is unusually long for a FTSE 100 CEO departure. In theory, it gives the board time to run a thorough succession process and ensures institutional knowledge transfers cleanly. In practice, it raises a pointed question: can a chief executive whose next job is already confirmed maintain the authority and focus needed to push through difficult decisions?
The French turnaround demands exactly that. Restructuring underperforming store networks, renegotiating supplier terms, and potentially closing sites all require a leader whose credibility with local management teams is unambiguous. A CEO with one foot out of the door may struggle to command the room.
The AI rollout adds a second layer of complexity. Garnier himself described Kingfisher as "an early adopter" of AI-driven retail in a results call earlier this year, according to City AM, and the Google Cloud partnership is still being deployed across multiple brands. Technology programmes of this scale need sustained executive sponsorship; they do not run on autopilot.
There is precedent for concern. Garnier's predecessor, Véronique Laury, surprised investors when she announced a shock departure after a drastic overhaul of the business left profits heading downwards, as City AM reported. That exit, less than a decade ago, disrupted strategic momentum and left the board scrambling. A second disruptive transition in quick succession would test investor patience.
"I remain focused on continuing to execute on our strategic plans with all my energies, so as to leave Kingfisher in the best possible shape for the future," Garnier said in the company's statement on Wednesday.
The words are reassuring. Whether they translate into twelve months of genuine operational grip is the question the board, and the market, will be watching.
Why Ahold Delhaize came calling
Ahold Delhaize operates a global portfolio of supermarket and convenience store brands, with a market capitalisation of approximately €35bn. Garnier's experience running a multi-brand, multi-country retail group maps neatly onto the Dutch-Belgian firm's structure.
His track record at Kingfisher, particularly the marketplace launches and the push into AI-assisted shopping, signals a comfort with digital transformation that grocery retailers are increasingly prioritising. Before Kingfisher, Garnier held senior roles at Carrefour, giving him deep fluency in continental European retail, a critical asset for a group with significant operations in Belgium and the Netherlands.
The move also reflects a broader pattern in European retail leadership. Chief executives with cross-border, multi-format experience are in short supply, and Ahold Delhaize evidently concluded that securing Garnier was worth the lengthy wait imposed by his notice period.
What the board should prioritise in a successor
Kingfisher's next chief executive will face a bifurcated business. The UK arm is expanding and profitable; the French arm needs surgery. The succession brief, in effect, asks for two skill sets that rarely sit in the same person: a growth operator for Britain and a restructuring specialist for France.
The board will also need someone willing to inherit and accelerate the AI and marketplace strategies rather than reset them. Strategic restarts are expensive, and Kingfisher's investors have already lived through one post-departure pivot under Laury's successor.
Timing matters. The longer the search takes, the longer the organisation operates under a departing leader. If the board can identify and announce a successor well before April 2027, it can run a structured handover rather than a prolonged interregnum. If it cannot, the risk is twelve months of strategic drift at precisely the moment the French business can least afford it.
Kingfisher's split performance, strong in the UK and faltering in France, makes the next appointment one of the more consequential succession decisions in FTSE 100 retail this year. The board's speed and judgement will determine whether Garnier's departure is a managed transition or a repeat of the disruption that followed Laury's exit.
