Partnering forever? Challenging the assertion that health systems are always partnering in permanence
March 18, 2026 – Banker Commentary by Dan Gold
U.S. health systems frequently assert that partnering with private equity (PE) is misaligned with their mission, because private equity funds must exit investments within a predetermined time period (usually five to seven years), while health systems are presumed to invest “for the long term.” This argument has become a common rationale for avoiding or limiting PE partnerships. However, real-world behavior suggests a different reality: health systems often invest only until leadership changes or strategic priorities shift. The evolution of Ascension Health’s ambulatory surgery (ASC) strategy, moving from an exclusive private equity-backed joint venture with Regent Surgical Health to a wholly different, directly owned platform through its pending acquisition of AMSURG, suggests that health system capital is often far less permanent than rhetoric implies.
The Claimed Time-Horizon Mismatch
Health system executives routinely contrast their purportedly perpetual investment mindset with private equity’s finite fund life. The implication is that PEs’ need to monetize may create misaligned incentives or instability, while health systems are investing to support core service lines that will serve their patients long beyond the life of said PE’s fund. This framing positions PE exits as a structural flaw rather than a design feature. Yet this narrative assumes that health systems themselves maintain consistent strategies over decades. In practice, strategy is inseparable from leadership, and leadership is not static.
Ascension and Regent: A “Long-Term” Partnership
In March 2021, Ascension Capital partnered with TowerBrook Capital Partners to make a strategic investment in Regent Surgical Health, a national developer and manager of ASCs. As part of the transaction, Ascension formed an exclusive national partnership with Regent for ASC development, explicitly signaling a system-wide, long-term commitment to the platform. At the time, the structure reflected the very alignment health systems often claim to seek: PE provided growth capital, Regent supplied operating expertise, and Ascension gained a scalable outpatient strategy without fully internalizing execution risk.
A Change in Course, Not in Market Logic
In June 2025, Ascension announced an agreement to acquire AMSURG, one of the largest ASC operators in the country. This transaction represented a decisive shift toward direct ownership and control. Critically, between March 2021 and June 2025, Ascension had key leadership changes. Presumably, the new Ascension team’s decision reflects not a rejection of outpatient care, but a change in how this new leadership wanted to own and govern that strategy.
What Actually Shortened the Investment Horizon
Nothing in the public record suggests that TowerBrook’s fund life forced Ascension’s hand. Further, Ascension and TowerBrook continue to partner in other disciplines (e.g., revenue cycle management). Instead, the shift coincided with broader organizational changes, including leadership turnover, financial restructuring, and a push toward simplification. The effective exit clock on the Regent partnership appears to have been driven not by private equity’s need to sell, but by Ascension’s willingness to change course once a new management team articulated a different vision.
The Real Asymmetry
Private equity is explicit about its exit requirements. While health systems often describe their investments as permanent, the Ascension example shows that, in practice, they retain and exercise the ability to redirect capital and unwind prior strategies when leadership changes. In effect, health systems may not invest forever; they invest until they no longer want to.
Implications
This reality has implications for health system executives. Health systems should be more open to partnering with PE, as the benefits of disciplined, focused growth and business building could greatly benefit many areas across their business. Further, PE investment horizons present optionality for health systems: there exists a natural opportunity to either own the whole business (buy out the PE partner), monetize alongside PE, or seek out a new partner better equipped for the business’s next phase of growth.
Conclusion
The belief that health systems cannot partner with private equity due to mismatched time horizons rests on an idealized view of permanence. The Ascension–TowerBrook–Regent–AMSURG sequence demonstrates that health system investments are often just as finite — defined not by fund documents, but by leadership change. In that context, private equity’s explicit exit discipline may make the two parties more aligned than health systems have historically been willing to acknowledge.
