Diageo CFO swap|Lewis’s Tesco ally as third finance chief in under three years?

A finance chief leaves after the plan

Diageo, the maker of Guinness and Johnnie Walker, has named WPP’s finance chief, Joanne Wilson, as its next chief financial officer. She replaces Nik Jhangiani, who helped present Diageo’s turnaround plan to investors less than two months before. Wilson will be Diageo’s third finance chief in less than three years. And she is not due to arrive until some point in 2027.

The man who picked her is Sir Dave Lewis, the former Tesco boss who became Diageo’s chief executive in January. Wilson spent ten years at Tesco, a spell that overlapped with his time in charge. Jhangiani was himself a replacement. He became finance chief in 2024, after the departure of Lavanya Chandrashekar. Her exit followed problems with excess stock in Latin America.

That contributed to a damaging profit warning in the autumn of 2023. The same year, long-serving chief executive Ivan Menezes died after a brief illness. A run of leadership changes followed. When chief executive Debra Crew left, Jhangiani ran the company on an interim basis from July to December 2025. When Lewis took over, Jhangiani went back to the finance job. Through all that churn, Jhangiani was the constant.

Some analysts had seen him as a contender to keep the top job permanently. Jefferies says he was central to shaping the current strategy. It says investors regarded him well for his focus on execution, growth and cash delivery. He also oversaw the Accelerate programme. It delivered 540 million dollars of cost savings in the 2026 financial year. Yet he is the one leaving.

Lewis explained the timing in Diageo’s statement. “Nik and I have agreed that, now we have shared our new strategy, this is the right time for this change.” Lewis ties the timing to the strategy being published. Jhangiani said he was proud to have helped present the three-year financial plan to investors. Analysts were less settled.

Seamus Cassidy of TD Securities called the decision surprising, given Jhangiani had been seen as a potential chief executive. He said the move “may reflect efforts to build a leadership team more aligned with Lewis’ strategic vision”. If Cassidy is right, the answer lies less in Jhangiani’s record than in who Lewis chose instead.

Why Lewis wanted Wilson

Wilson’s decade at Tesco ran to 2016. She was head of mergers and acquisitions, and director of finance. Lewis ran Tesco from 2014 to 2020. Wilson later became finance chief of dunnhumby, Tesco’s data science business. Dan Coatsworth of AJ Bell summed it up: “Dave Lewis is getting the old gang back together again.” He called hiring former colleagues a classic move by leaders who want people they trust.

Lewis earned the nickname Drastic Dave for aggressive cost-cutting at Unilever, before turning Tesco around. At Diageo, he is seeking about one billion dollars in savings. Jefferies points to Wilson’s strong record on cost efficiency, simplification and cash conversion. Lewis says she has “already delivered extensive transformations in her previous companies”. Her pay ties her closely to Diageo’s share price.

Her base salary is 900,000 pounds, and her annual bonus can reach twice that. A long-term share award can reach five and a half times salary. That still needs shareholder approval at the annual meeting in November. She must also build a Diageo shareholding worth five and a half times salary. That comes to about 4.95 million pounds, in a stock down about 53 per cent over five years.

The gap before 2027

The two companies describe Wilson’s coming year in very different terms. Lewis calls her a leader “who will ensure we accelerate the turnaround of Diageo”. WPP’s chief executive, Cindy Rose, looks at the same months from the other side. She said she was “grateful that Joanne will continue to work with me in ensuring continuity”. WPP’s announcement adds what neither quote says.

Wilson is on a twelve-month notice period, and her leaving date is still to be agreed. The Irish Times called Diageo’s “some time in 2027” a notably vague timeline for someone so senior. WPP is mid-overhaul too, and Rose credits Wilson with delivering phase one of its Elevate28 plan. Meanwhile, Lewis says Jhangiani “will remain in role to ensure a smooth handover to Joanne”.

So the plan’s first year runs with a departing finance chief, and a successor still working elsewhere.

Where the plan meets resistance

Cost is where Wilson’s record is meant to count. Diageo has already cut 2,000 jobs in the past twelve months. Reuters reported in July that some teams would shrink by as much as a third. Lewis has spoken of “massive duplication” in parts of the business. The savings are meant to pay for reviving brands such as Smirnoff and Captain Morgan, where sales have fallen. Now the cuts face a strike.

From the twenty-eighth of September, more than 100 Unite members are set to walk out at the Cameronbridge distillery in Scotland. Some groups will stay out until early on the fifteenth of October. Unite expects the strike to bring production to a standstill. The two sides describe the cuts on very different scales. Unite says Diageo plans to cut hundreds of jobs in Scotland, where it employs about 3,000 people.

Diageo says only eight of the 72 grain-distilling posts at Cameronbridge would go. Two more posts are already vacant. Unite’s general secretary, Sharon Graham, said there was “no justification for slashing hundreds of jobs across its operations”. She pointed to the hundreds of millions in profit Diageo makes.

What decides it

The cutting matters because of what the latest results show. In its 2026 financial year, revenue fell 3 per cent to 19.6 billion dollars. Reported operating profit plunged 27.2 per cent. That was heavily distorted by 2.4 billion dollars of restructuring and impairment charges. Underlying operating profit rose 2 per cent, and free cash flow jumped 17 per cent. Organic revenue still fell 2 per cent.

Jefferies notes the plan does not bank on a rebound in the American market. It is about execution. Jefferies expects the market to take Jhangiani’s departure negatively. But it says the change makes little difference to the turnaround. Its argument is that the plan is embedded enough to survive a change at the top. That is the fork. If the plan is embedded, a long handover costs little.

If it depends on the people who wrote it, the gap before 2027 is where that shows. The opening puzzle now reads differently. Lewis let go the finance chief who helped write the plan, and chose a colleague he knows to speed it up. The price is a handover of up to a year, just as the cuts meet open resistance. The first read comes on the fifth of November, with Diageo’s first-quarter trading update.

If it shows the plan gaining traction, Jefferies’ view gains weight, and shareholders benefit. If it disappoints, the long wait for Wilson becomes the central question, and shareholders carry that risk.
