The largest healthcare platform in the UAE, Pure Health, has signed an agreement with Equity Group Investments to invest $500 million in a U.S. healthcare company.

The largest integrated healthcare platform in the United Arab Emirates and a subsidiary of Alpha Dhabi Holding, Pure Health, announced that it has signed a definitive purchase agreement to pay $500 million for a minority equity investment in Ardent Health Services, a top U.S. healthcare provider with headquarters in Nashville, Tennessee. The investment will be completed upon the acquisition of all required U.S. regulatory approvals, subject to customary closing circumstances.

At 30 hospitals and over 200 care locations spread across six states, Ardent is the fourth-largest privately held acute care hospital operator in the United States, employing about 26,000 people. By acquiring a portion of Ardent from Equity Group Investments, a Chicago-based private investment group that now owns the majority of the company, Pure Health would be able to obtain a minority equity investment.

Pure Health would not have a seat on Ardent’s board of directors, but it would enjoy board observer rights as part of its investment. The investment does not involve any intentions to increase Ardent’s physical footprint or to work with Pure Health to provide services together. At the signing event, which was organized by Equity Group Investments, attendees included Marty Bonick, president and chief executive officer of Ardent, Sam Zell, founder and chairman of EGI, and Farhan Malik, CEO of Pure Health.
