The Man Who Built UnitedHealth Into an Industry Giant Now Has to Turn It Around

Stephen Hemsley never fully dropped the reins when he stepped down as UnitedHealth Group Inc.’s chief executive officer eight years ago. With the health giant in crisis, he’s taking back his old job – and confronting one of the toughest turnaround tasks any executive has ever faced.

Widely credited with building UnitedHealth into the conglomerate it is today, Hemsley, 72, was reluctant to end his tenure as CEO in 2017, according to people familiar with the matter who asked for anonymity to describe internal company discussions. The board had asked him to step aside at age 65, but he wanted to remain involved in operations as executive chairman, the people said.

The company disputed the characterization that Hemsley didn’t want to step down, saying UnitedHealth doesn’t have a mandatory retirement age and he worked with the board for more than a year on transition planning.

UnitedHealth is betting that Hemsley can fix operational stumbles while sticking with its strategy to broaden and deepen its reach into more areas of health care. As CEO, he had presided over a period in which its business rapidly expanded and evolved. He made the crucial decision to build the company’s pharmacy-benefits operation, which now accounts for a large share of its profits.

During his time as CEO and after, UnitedHealth delivered reliable profit growth as it reached unrivaled scale. From the start of Hemsley’s tenure through last year, shares of UnitedHealth gained more than 900%.
