Megamerger alert: Steward Health Care to become largest private for-profit hospital operator in the U.S.

A new merger between Steward Health Care and IASIS Healthcare LLC will make the Boston-based physician-led organization the largest private for-profit hospital operation in the country.

The deal with the Tennessee hospital system means Steward will have 36 hospitals across 10 states, managed care operations in Arizona, Utah and Massachusetts, and projected revenues of almost $8 billion in 2018.

Steward announced the merger this morning and said it expects to seal the deal in the third quarter of 2017. Terms of the transaction were not disclosed.

The organization already operates 18 hospitals and employs more than 1,300 multi-specialty physicians throughout Massachusetts, Ohio, Florida and Pennsylvania. IASIS operates 17 hospitals and one behavioral health hospital in locations across Utah, Arizona, Colorado, Texas, Arkansas and Louisiana.

The merger will result in Steward operating nearly 7,500 patient beds across 10 states with approximately 38,000 employees, including more than 1,800 directly employed multi-specialty physicians and several thousand aligned physicians.
