Allina Health to be acquired by California-based nonprofit health system

Sutter Health, a Sacramento-based nonprofit health system, announced plans to acquire Minneapolis-based Allina Health, pledging a $2 billion investment across Minnesota and Wisconsin operations. The deal represents a significant consolidation in the regional healthcare market, combining two major nonprofit systems that collectively serve millions of patients across the upper Midwest and California. Healthcare unions have objected to the merger, stating that workers were not consulted during the planning process, raising concerns about potential job impacts and labor practices. The acquisition still requires regulatory approval and must navigate scrutiny from antitrust authorities and state health officials. Sutter Health operates more than two dozen hospitals and medical centers primarily in Northern California, while Allina operates dozens of clinics and hospitals across the two-state region.
