Sutter Health and Allina Health, both nonprofit health systems, have reached a definitive agreement to join forces, advancing the Sutter-Allina acquisition toward close. The healthcare acquisition would bring together 18,000 physicians and 88,000 other employees serving more than five million patients across California, Wisconsin and Minnesota. As part of the hospital consolidation, Sutter Health says it will invest more than $2 billion in the Allina system throughout Minnesota and western Wisconsin to support patient access and outcomes, recruit physicians, and advance clinical research.
According to Sutter Health, planned investments include new ambulatory care centers, expansion of specialty care centers, and support for clinical trials, with an emphasis on patient access across the region. “We look forward to continuing to learn from one another and working together to shape a future where health care is more connected and easier to navigate for every patient,” Sutter Health President and CEO Warner Thomas said. “Health care is becoming more complex and demanding, both for patients trying to access care and for the people delivering it. Together, we will lead the way to accelerate solutions, recruit more physicians and expand locations to improve access and redesign how care is delivered for our patients and communities.”
Allina Health employs more than 28,000 people and operates Minneapolis’ Abbott Northwestern Hospital, the largest nonprofit hospital in the Twin Cities area. The Sutter-Allina acquisition, as a healthcare acquisition between nonprofit health systems, is positioned to integrate multispecialty care and support patient access through expanded facilities and services.
The transaction is expected to close by the end of 2026, subject to regulatory approval. Minnesota Attorney General Keith Ellison is seeking community input as part of his office’s review, which he said “requires close scrutiny.” “As we have done with other transactions, we are conducting a thorough review of this potential acquisition to ensure it complies with the law and is in the public interest,” Ellison said in mid-April. The hospital consolidation also drew response from labor groups. Two unions representing thousands of Allina Health workers SEIU Healthcare MN & IA and Doctors Council-SEIU have expressed concerns about potential impacts on employees, contracts and pension plans. “A key issue is ensuring that charitable assets built up by Minnesotans are not diverted out of state or to a small handful of executives for personal enrichment,” the unions said in a joint statement.
With the definitive agreement in place, the nonprofit health systems will proceed through the required processes, including ongoing community input and regulatory approval. The organizations have cited improved patient access, physician recruitment, and support for clinical research as priorities as the hospital consolidation advances toward an anticipated closing by the end of 2026, pending regulatory approval.
