Amazon, Berkshire Hathaway and JPMorgan Team Up to Disrupt Health Care

SEATTLE — Amazon, Berkshire Hathaway and JPMorgan Chase announced on Tuesday that they would form an independent health care company to serve their employees in the United States.

The three companies provided few details about the new entity, other than saying it would initially focus on technology to provide simplified, high-quality health care for their employees and their families, and at a reasonable cost. They said the initiative, which is in the early planning stages, would be a long-term effort “free from profit-making incentives and constraints.”

The partnership brings together three of the country’s most influential companies to try to improve a system that other companies have tried and failed to change: Amazon, the largest online retailer in the world; Berkshire Hathaway, the holding company led by the billionaire investor Warren E. Buffett; and JPMorgan Chase, the largest bank in the United States by assets.

It also illustrates the rapid changes affecting the sector in the United States, where lines that have separated traditionally distinct sectors, like care provision and insurance, are increasingly blurred. CVS Health’s deal last month to buy the health insurer Aetna for about $69 billion is just one example of the shifts underway.

“The health care system is complex, and we enter into this challenge open-eyed about the degree of difficulty,” Jeff Bezos, Amazon’s founder and chief executive, said in a statement. “Hard as it might be, reducing health care’s burden on the economy while improving outcomes for employees and their families would be worth the effort. Success is going to require talented experts, a beginner’s mind, and a long-term orientation.”

Amazon has long been mentioned by health care analysts and industry executives as a potential new entrant into the sector. But much else is also changing, from possible changes to government programs like Medicare after the overhaul of the tax law, to the uncertain future of the Affordable Care Act. All the while, medical costs have persistently been on the rise.

“The ballooning costs of health care act as a hungry tapeworm on the American economy,” Mr. Buffett said in the statement on Tuesday. “Our group does not come to this problem with answers. But we also do not accept it as inevitable. Rather, we share the belief that putting our collective resources behind the country’s best talent can, in time, check the rise in health costs while concurrently enhancing patient satisfaction and outcomes.”

The announcement on Tuesday again highlighted investor worry about Amazon disrupting the health care industry. Shares of UnitedHealth were down 5 percent in premarket trading, while Anthem’s were down 3.5 percent, erasing many of the gains such companies have made over the past 12 months.
