Bon Secours Mercy Health’s $5.7 Billion Bet on Surgery Centers: What the Surgery Partners Take-Private Signals

Nonprofit hospital systems have spent years talking about moving care out of the hospital. Bon Secours Mercy Health just put $5.7 billion behind that idea. On October 26, HealthSpan Partners, an affiliate of the Cincinnati-based Catholic health system, agreed to acquire Brentwood, Tennessee-based Surgery Partners and take it private. If the deal closes as planned, a system known for hospitals will become one of the largest operators of ambulatory surgery centers in the United States.

For executives watching health care consolidation, the transaction is notable less for its size than for its shape: a nonprofit system acquiring a for-profit, private-equity-backed outpatient platform, while the private equity investor stays in the deal.

The deal terms

According to Reuters, as published by KFGO, the transaction values Surgery Partners at about $5.7 billion including debt. Shareholders other than Bain Capital affiliates will receive $23.50 per share in cash, a 49% premium to the stock’s last close before the announcement, and the shares jumped 46% on the news. Bain Capital, a minority shareholder since 2017 that owns about 39% of the company, will roll its stake into equity in the acquiring entity and remain a significant partner, Becker’s Hospital Review reported.

The agreement ends a two-year strategic review at Surgery Partners. Reuters noted that a bid by Bain to take the company private last year had been rejected.

HealthSpan plans to fund the purchase with cash on hand and new debt, for which it has secured commitments. Surgery Partners will keep its operations, name, brand and headquarters, and Becker’s reported that the company will not be treated as a Catholic ministry entity. The transaction is expected to close in the first quarter of 2027, pending shareholder and regulatory approvals.

What Bon Secours is buying

Surgery Partners operates more than 200 locations across 30 states, including ambulatory surgery centers, surgical hospitals, multi-specialty physician practices and urgent care facilities, with about 5,000 affiliated physicians, according to Becker’s. The company reported $3.3 billion in revenue in 2025 with an 11.8% operating margin, compared with $3.1 billion and a 12.5% margin in 2024.

Bon Secours Mercy Health, by contrast, reported 2025 operating income of $305.6 million on $14 billion in revenue, a 2.2% operating margin, up from $133.3 million on $13.3 billion, or 1%, in 2024. The comparison explains much of the strategic logic. Outpatient surgery has historically produced healthier margins than inpatient hospital care, and procedures continue to shift toward lower-cost settings.

Bon Secours has framed the acquisition around access. Its chief executive, John Starcher Jr., described the deal to Becker’s as an important step toward the system’s goal of improving access to affordable care. Digital Health News, summarizing the announcement, reported that the system expects the deal to broaden its care delivery network as more procedures move to outpatient settings, and said the combination aims to create one of the largest outpatient surgical care platforms in the country. For patients, the practical promise is more surgical options outside the hospital, often at lower cost; for the system, it is exposure to the fastest-growing part of procedural care.

Surgery Partners had already been reshaping itself. In September, it sold two hospitals to Intermountain Health for $797 million, with most of the net proceeds going to pay down debt, Becker’s reported.

The competitive landscape

The acquisition places Bon Secours among a small group of very large outpatient surgery operators. Becker’s laid out the field: Tenet Healthcare’s United Surgical Partners International has ownership interests in 535 ambulatory surgery centers and 25 surgical hospitals; Optum’s SCA Health includes more than 340 centers; Ascension has more than 320 after buying Amsurg for $3.9 billion in June; and HCA’s Surgery Ventures operates and jointly owns about 150 surgery and endoscopy centers.

Two of those players, Ascension and now Bon Secours, are nonprofit Catholic systems that chose to buy national outpatient platforms rather than build them. That is a meaningful pattern. Building an ambulatory network one center at a time takes years of physician recruitment, site development and payer contracting. Buying an established operator delivers scale, management talent and physician relationships at once.

The system has also been growing in its traditional business. Becker’s reported on November 3 that Bon Secours had completed its acquisition of 97-bed Fauquier Health in Warrenton, Virginia, from Lifepoint Health, its first hospital in Northern Virginia and its 48th overall.

Antitrust and execution risks

Regulators have scrutinized health care deals closely, but analysts did not flag this one as a major antitrust concern. Mizuho analyst Ann Hynes told Reuters that “there is some market overlap in Ohio and Kentucky,” and said the companies do not expect meaningful antitrust risk from the Federal Trade Commission. She added that Bain keeping its stake should help the deal close.

Execution is a different question. Integrating a for-profit, physician-partnered surgical business into a nonprofit system involves cultural and governance issues, including how physician ownership is structured, how capital is allocated between hospitals and outpatient sites, and how the arrangement is viewed by state regulators and community stakeholders. The decision to keep Surgery Partners’ brand and headquarters and to not treat it as a Catholic ministry entity suggests the parties intend to run it at arm’s length.

Lessons for health care executives and dealmakers

• Nonprofit capital is pursuing for-profit platforms. Large systems are using affiliates and joint structures to acquire growth businesses that do not fit neatly inside a hospital ministry.
• Private equity does not always exit. Bain rolling its stake shows a model in which the financial sponsor stays alongside a strategic acquirer, sharing upside and expertise.
• Portfolio pruning precedes a sale. Surgery Partners’ sale of two hospitals to Intermountain before the deal is a reminder that sellers often simplify their asset base to sharpen their story.
• Margin gaps drive strategy. When outpatient businesses earn several times the operating margin of the parent system, buying them can shift the economics of the whole enterprise.
• Brand separation is a tool. Keeping an acquired brand independent can protect physician relationships and avoid friction with religious or community governance requirements.

Practical steps if you operate in outpatient surgery

1. Know your local market overlap. If a large system now owns a competitor in your area, expect changes in referral patterns and payer negotiations.
2. Review physician partnership terms. Consolidation often brings new offers for physician-owned centers. Understand your valuation drivers, buy-sell provisions and noncompete terms before conversations start.
3. Prepare for diligence. Buyers will examine case mix, payer contracts, quality metrics and regulatory compliance. Clean data shortens timelines and supports value.
4. Watch state transaction-review rules. A growing number of states require notice of health care transactions. Build that into any deal timeline.
5. Engage advisers early. Health care transactions involve antitrust, fraud-and-abuse and tax considerations that require qualified legal and financial counsel.

What to watch

• Shareholder and regulatory approvals ahead of the targeted first-quarter 2027 closing.
• Integration choices, including whether Bon Secours steers more of its own outpatient volume to Surgery Partners sites.
• Financing costs, since the deal relies partly on new debt, and borrowing costs will affect how quickly the combined business can reinvest.
• Copycat deals. With Ascension and Bon Secours both buying national outpatient platforms, other large systems may look for similar targets.
• Payer reaction. Larger outpatient networks tied to health systems can change negotiating leverage with insurers.

The bottom line

The Surgery Partners deal is a clear marker of where health care strategy is moving: toward outpatient procedures, toward scale and toward hybrid structures that blend nonprofit missions with for-profit operating models and private capital. Whether it delivers the margin and access improvements Bon Secours expects will depend on execution, but the direction of travel is unmistakable.
