Having the right leadership in place can make or break a retailer’s fortunes. As consumer price sensitivity mounts and industry competition intensifies, grocers have updated — and in some cases overhauled — their executive ranks in order to stay in fighting form.

Companies like Kroger and Ahold Delhaize named fresh faces to the top of their respective companies. Since taking the helm at Kroger in February, former Walmart U.S. president Greg Foran has laid out an ambitious plan to lower prices and also improve the retailer’s image as a destination for fresh food. A flurry of executive moves have come in the wake of his appointment.

Ahold Delhaize, meanwhile, tapped new CEOs for both its overall business and U.S. division after former leaders Frans Muller and JJ Fleeman announced plans to step down. With Thierry Garnier and Claire Peters set to take the lead roles at Ahold Delhaize and Ahold Delhaize USA, respectively, big changes could soon be afoot at the East Coast grocery giant.

While several grocers have made CEO changes this year, other companies have made notable changes further down the pecking order. United Natural Foods, Inc., which is in the midst of a push under CEO Sandy Douglas to improve sales, reworked its C-suite earlier this summer to better fit its evolving strategy. In April, the company named its first chief digital services officer.

Regional grocers have also made significant changes to their executive ranks as they struggle to compete with large-scale competitors. The Raley’s Companies, which named a new CEO back in March, last month made three executive changes, including naming a new chief marketing officer with expanded oversight. Market Basket, which was once again locked in a bitter dispute involving its former CEO Arthur T. Demoulas, named a new president.

Here’s a closer look at these and other key executive changes that have taken place in the grocery industry so far this year.
