The bread maker announced that after three years in the role Jenkins would be departing the business, effective from mid September.
Jenkins joined the firm as CEO in October 2022 after more than two and a half years as the chief executive of Müller UK & Ireland.
The news comes not long after it was announced that Associated British Food had reached an agreement with Hovis owner Endless LLP to acquire the brand in a deal worth around £70 million, according to Sky News.
Jenkins previously worked for Allied Bakeries, the baked goods division of Associated British Food.
Moving forward, the Hovis executive board said that it will “continue to deliver the strategic direction” of the brand, while “providing retailers and consumers with the great service and high-quality products they are used to”.
Commenting on his departure, Jenkins said: "I have thoroughly enjoyed my time at Hovis and would like to thank all our incredible colleagues across our bakeries, milling operation and distribution centres for their commitment and support over the last three years.
“I am really proud of what we have achieved and I look forward to seeing the business continue to prosper in the future.”
Meanwhile, Endless managing partner Aidan Robson commented: “I would like to thank Jon for his support and leadership over the last three years. Jon has helped navigate Hovis through an unprecedented period of raw material inflation and further developed the much-loved Hovis range of products and brand. Jon leaves with our thanks and best wishes.”
