Celebrating its 100th anniversary, Tesco, which has a 27.4% share of Britain’s grocery market, is in the final stages of a recovery plan that Lewis instigated after a 2014 accounting scandal capped a dramatic downturn in its fortunes.
“With the turnaround complete and as we begin to implement the next steps of our sustainable growth strategy, now is the right time to plan a smooth and orderly succession,” Lewis, who joined Tesco from Unilever in 2014, said on Wednesday.
“As such, I will step down as group CEO next summer and pass the baton to Ken Murphy.”
The group has met the majority of its turnaround goals, including a key margin target of earning between 3.5 pence and 4 pence of operating profit for every pound customers spend.
Lewis has overhauled Tesco’s relationship with suppliers, lowered prices versus competitors, simplified product ranges and improved store standards since taking charge. Jobs have also been cut, including 4,500 announced in August.
The 54-year-old has also pursued growth by buying wholesaler Booker, forming a global purchasing alliance with Carrefour <CARR.PA> and launching a new discount format called Jack’s.
The announcement of Lewis’s departure came as Tesco reported a better-than-expected first-half operating profit before one of items of 1.41 billion pounds, a rise of 25.4%.
The retailer said it had a “strong start” to the year and was well positioned to be highly competitive in a challenging market.
Lewis’s successor Murphy was joint chief operating officer at Boots UK & Ireland before rising to executive vice president, chief commercial officer and president global brands at Walgreens Boots Alliance.
