Rush and Endeavor Plan a 12-Hospital, $11 Billion Chicago System, Targeting an Early-2027 Close
The merger would pair Rush University System for Health's academic medicine with Endeavor Health's suburban footprint. It is the largest hospital combination announced this month.
Rush University System for Health and Endeavor Health have announced plans to merge, creating a 12-hospital system with roughly $11 billion in combined revenue. The organizations are targeting a close in early 2027, subject to regulatory review.
The shape of the deal
- Rush brings an academic medical center and a research engine anchored on Chicago’s Near West Side.
- Endeavor brings a broad suburban network built through its own string of mergers over the past decade.
- Together they would rival the largest systems in Illinois by revenue and by hospital count.
The wider week in hospital M&A
The Rush-Endeavor announcement landed in a busy stretch for provider deals:
- Parkview Health is acquiring Ovation Healthcare outright, becoming its sole owner.
- Healthspan Partners, the U.S. affiliate of Bon Secours Mercy Health, agreed to buy Ireland’s Centric Health for about €350 million, pending regulatory approval.
- Kaiser Permanente’s Risant Health signed a definitive agreement for INTEGRIS Health in Oklahoma, its third system.
What to watch
Academic-plus-community mergers draw close antitrust attention, especially in a single metro market. Expect state and federal reviewers to focus on pricing power and service overlap in Chicago’s western and northern suburbs. For executives elsewhere, the deal is another signal that scale, not standalone prestige, is the operating model boards are betting on.
