Hertz is making some major changes to its leadership team.

The rental car giant said it’s adding four former Delta Air Lines executives to the company this month and has promoted interim general counsel Katherine Lee Martin to executive vice president, general counsel and corporate secretary, effective immediately.

In a news release, Hertz said the additions will “sharpen the company’s focus on driving enhanced profitability through operational excellence, superior customer service, strategic fleet management, cost control and premium revenue.”

The new hires include executive vice president and chief commercial officer Sandeep Dube, executive vice president of North America operations Henry Kuykendall, executive vice president of fleet management Greg May and executive vice president of technical operations Mike Moore. All will report directly to CEO Gil West.

“The leaders announced today, along with our new chief financial officer Scott Haralson, add capacity and capabilities that complement our existing leadership team’s deep institutional knowledge of the rental car industry,” West said in a news release.

“We are now set to execute our strategy to deliver sustainable growth and create value by excelling at the basics, elevating our operational performance across every facet of our business with continued process improvement, technological and product innovation, and mobilizing our best and most valued asset — our 27,000 employees globally — to deliver an unmatched customer experience.”

The company said Dube, who comes on board after a year as Mailchimp’s chief operating officer, will lead Hertz’s global commercial strategy and revenue generation through an “integrated customer-centric approach,” overseeing revenue management and pricing, corporate sales and strategic partnerships, customer experience, product development, loyalty programs, marketing and franchise. His 25-plus years of experience also includes senior leadership roles with Delta.

Kuykendall served 33 years in various position for Delta, most recently as senior vice president of airport operations East, which included oversight of airports in New York, Boston and Detroit. He will lead Hertz’s airport and off-airport car rental operations in North America.

May will direct all aspects of Hertz’s fleet management, including fleet procurement and strategy, analytics and vehicle remarketing. His 35-year career includes managing commercial aviation fleets and supply chains in leadership positions with Delta, Northwest and United airlines. He also founded aircraft leasing company Q Aviation and launched and led Valkyrie BTO Aviation, a commercial aircraft investment company for Blackstone.

Moore, who will take charge of all aspects of Hertz’s fleet maintenance, has more than 25 years of experience managing fleet operations and maintenance, bringing expertise in overseeing operations and delivering process improvements that reduce costs and drive enhanced financial performance, the company said. He spent a decade in operations-focused roles of increasing responsibility with Delta and has also worked for Northwest Airlines and as executive vice president of spaceline technical operations with Virgin Galactic.

Martin will continue to oversee Hertz’s global legal affairs and government affairs, as well as the sustainability and social impact teams. Martin took over as interim general counsel and assistant corporate secretary in April after joining Hertz in May 2023 as vice president and chief counsel. She previously oversaw Twitter’s global portfolio of litigation, regulatory and competition matters, and spent more than a decade with the U.S. Department of Justice as an assistant U.S. Attorney.

“Our enhanced executive team, and the added resilience and flexibility afforded by the capital we recently raised, enable us to pursue our fleet rotation plan on an accelerated timeline, deliver our cost and revenue improvement initiatives and allow Hertz to reach its full potential,” West said. “We are at an exciting inflection point in our path to generate greater value for our customers, employees and shareholders.”
