Howard Hughes Holdings, a diversified holding company, has announced that former leaders at Arch Capital Group, Marc Grandisson and David Gansberg, have been appointed as Executive Chairman and Chief Executive Officer (CEO), respectively, of Vantage Group Holdings.
Howard Hughes completed its $2.1 billion acquisition of specialty insurance and reinsurance company Vantage in June 2026.
Back in April, the firm welcomed Grandisson, the former CEO of Arch Capital, to its Board of Directors. Today, it’s been revealed that, effective immediately, Grandisson will serve as Executive Chairman of Vantage.
Grandisson joined the Arch Capital founding team in 2001 after starting his career with insurance executives including Ajit Jain from Berkshire Hathaway, and Paul Ingrey at F&G Re. He led Arch as CEO from 2018 until his retirement in 2024. During his tenure as CEO, Arch generated a total shareholder return of 298%, or 23.2% per annum.
Gansberg will take over as CEO of Vantage from Greg Hendrick, who has served as CEO of the re/insurer since co-founding the company in 2020, once his non-competition obligations are no longer in effect by June 2027.
Like Grandisson, Gansberg joined Arch in 2001, and from 2019 to 2024 he led the firm’s Global Mortgage Group as CEO, later being named as President of Arch Capital with accountability for its Global Insurance Group.
Bill Ackman, Executive Chairman of Howard Hughes, commented: “In Marc and David, we have two of the most accomplished leaders in the industry to guide Vantage into its next chapter.
“Greg has built the foundations for an exceptional specialty insurance and reinsurance operation, and we are grateful for his leadership. As we look to the future, Marc’s deep underwriting and operating expertise and David’s proven track record of building profitable, durable insurance businesses position Vantage to scale into a large, highly profitable insurance company and an enduring source of long-term value creation for Howard Hughes and its shareholders for decades to come.”
Grandisson said: “When I joined the Howard Hughes board, I saw a company at an exciting inflection point, and my conviction in the opportunity at Vantage has only grown since. Vantage is an exceptional diversified insurance platform which offers tremendous opportunity, and I am honored to join the company as Executive Chairman.”
Hendrick added: “Building Vantage these past six years has been the privilege of my career. We set out to build a specialty reinsurer that sees risk differently — one defined by talent, technology, and a genuine curiosity about the world. I am proud of every person who made it possible. With our recent sale to Howard Hughes, we are now closing our founding chapter and opening an extremely promising long-term future for the company. I am committed to a transition that sets up Marc, David and the Vantage team for even greater success in the future.”
