Sutter Health, Allina Health to form 39-hospital system

I worked for Sutter Health from 1998 to 2014. The last seven years I was the Vice President of Technical Services. I am fascinated by noncontiguous mergers in both health care and financial services. It will be interesting to see how this merger shakes out over the next five years.

Sutter Health, Allina Health to form 39-hospital system

Sacramento, Calif.-based Sutter Health and Minneapolis-based Allina Health have signed a letter of intent for Allina to join the health system, creating a combined nonprofit organization spanning California, Minnesota and Wisconsin.

The proposed transaction would create a system with 39 hospitals and more than 400 care sites, serving more than 5 million patients, according to a joint news release.

Upon closing, the combined system would include 18,000 physicians and 88,000 employees across Northern and Central California and Minnesota and Wisconsin.

Based on 2025 revenues, the combined organization would generate about $26 billion.

Sutter Health provides care to more than 3.5 million Californians through an integrated network of clinicians, hospitals and care sites. Allina Health operates more than 90 clinics, 12 hospital campuses and additional care services across Minnesota and western Wisconsin.

The organizations said the transaction aims to expand access and affordability, including plans to invest more than $2 billion in Minnesota and western Wisconsin to grow ambulatory care, expand specialty services and support digital and AI-enabled tools.

Under the proposed transaction, Allina Health would become Sutter Health’s Upper Midwest Division while retaining its board of directors, brand and regional headquarters in Minneapolis, the organizations said. The agreement is akin to a member substitution, though the final structure will be defined in a definitive agreement and reviewed by regulators. Sutter Health would maintain its headquarters in Northern California. Warner Thomas would continue to lead the combined system as president and CEO of Sutter Health, with Lisa Shannon remaining president and CEO of Allina Health as it becomes Sutter Health’s Upper Midwest Division.

Mr. Thomas and Ms. Shannon told Becker’s the transaction reflects alignment in strategy and long-term goals.

“At Allina Health, we have been thinking about partners that would enable us to better serve our community — partners that would value our strengths and share our aligned mission, our view of the future and our values,” Ms. Shannon said.

“This has been almost a yearlong journey discussing how we could better serve our communities together.”

Mr. Thomas said he believes “like-minded organizations with a common culture and a common view of the future are better together than apart.”

He said the transaction would bring together Allina’s clinical capabilities with Sutter’s investments in ambulatory care and digital infrastructure.

Mr. Thomas added that Allina is undergoing a multiyear effort to replace and expand its flagship Abbott Northwestern campus, creating an opportunity to pair those investments with Sutter Health’s experience scaling ambulatory care and digital capabilities. Mr. Thomas said leaders across systems see care continuing to shift into outpatient settings, making ambulatory expansion and clinician recruitment central to improving access.

Through the partnership, the organizations plan to expand ambulatory care, recruit additional clinicians and invest in technologies aimed at reducing administrative burden and improving patient access, including digital scheduling tools.

Leaders also pointed to complementary regional strengths, including Northern California’s role in AI and Minnesota’s position as a medtech hub, as factors in the proposed transaction.

Over the coming months, the organizations will complete due diligence and finalize terms before entering a definitive agreement. The transaction is expected to close by the end of 2026, pending regulatory approval.
