US off-price apparel and home fashion retailer Ross Stores has announced a series of leadership changes, including the promotion of Michael Hartshorn as group president and COO with overall responsibility for the supply chain. 

In his new role, Hartshorn, who has served as CFO since March 2019, will report directly to CEO Barbara Rentler and will add strategy, marketing, human resources, supply chain, stores, and technology to his current responsibilities.

Following his appointment, group senior vice president and deputy chief financial officerTravis Marquette is being promoted to group senior vice president and CFO.

Elsewhere, Michael Kobayashi has been named president, operations and technology and will report to Hartshorn. Kobayashi has served as group executive vice president, supply chain, merchant operations, and technology since 2014, and will be adding the stores organisation to his current responsibilities.

Reporting to him will be Gary Cribb, who is promoted to senior group executive vice president, stores and loss prevention.

The shakeup follows the departure of president and COO Michael O'Sullivan in April, and Rentler says: "Our strong bench of long-tenured and highly skilled senior management talent has enabled us to put in place an outstanding operational leadership structure to support the long-term needs of our business."

Ross Stores recently reported a rise in net earnings for the first quarter amid a 6% increase in sales for the period.

The company operates 1,523 Ross Dress for Less stores and 249 dd's Discounts locations.
