US department store retailer Macy’s Inc has outlined a series of changes to its senior leadership, including the elimination of the chief operations officer (COO) role.

In a statement, Macy’s said its current COO John Harper will depart the company effective 1 August, at which point the role will be terminated. Subsequently, Marc Mastronardi, chief stores officer, and Dennis Mullahy, chief supply chain officer, will report to Jeff Gennette, chairman and CEO.

Meanwhile, Laura Miller has been appointed chief information officer, effective 15 March. In this role, Miller will report directly to Gennette and will be responsible for the company’s information technology platforms and teams. She succeeds chief technology officer Naveen Krishna who is leaving the company.

In addition, Bluemercury, Inc’s CEO and co-founder Marla Beck will leave the company this summer. Macy’s has commenced a search for a new CEO who, once appointed, will report to Tony Spring, chairman and CEO of Bloomingdale’s.

While Chuck DiGiovanna, currently vice president, real estate, has been appointed to lead Macy’s real estate function, succeeding Douglas Sesler, who is leaving the company. 

“As a digitally led omnichannel retailer, Macy’s, Inc is in the midst of an exciting transformation,” said Gennette. “We are building a diverse leadership team that includes a blend of new talent with outside perspectives along with our tenured and best-developed leaders who will accelerate the progress of our Polaris growth strategy. I am confident that these changes in reporting structure will enable us to be nimbler and more efficient as we move forward in our recovery and drive top and bottom-line growth.”

Last month, Macy’s revealed plans to close 45 of its stores this year as part of its three-year plan to stabilise profitability and position the company for growth.

The Polaris Strategy, which was outlined last year will lead to further reshaping of Macy’s supply chain and includes plans to build four US$1bn “power” private brands.
