ASC Partner Buyout: Funding a Retiring Surgeon’s Shares
An ASC partner buyout happens when a surgeon who owns units in an ambulatory surgery center retires, relocates or stops operating there, and the center or the remaining owners purchase that interest. Because founding surgeons often hold large stakes, a single departure can create a significant funding need.
Planning ahead can protect both the departing partner and the center. This article explains how buyouts are generally triggered, how they may be structured and what lenders review. Ownership, investor and securities rules vary by state, and nothing here is legal, tax, billing or compliance advice.
What Triggers an ASC Partner Buyout
Most surgery center operating agreements include provisions that require or allow the repurchase of units in certain situations. Typical triggers include:
- Retirement or a planned reduction in clinical work
- Relocation outside the center’s market
- Disability or death
- No longer meeting the center’s investor requirements
- A voluntary decision to sell, subject to the agreement’s terms
The operating agreement usually controls who buys the units, how the price is set and how payment is made. Owners should review those terms with healthcare counsel well before a buyout is expected.
Who Buys the Departing Partner’s Units
There are generally three possible buyers, and the choice affects how the transaction is financed.
- The center itself: the entity redeems the units, often using cash, center-level debt or a combination
- The remaining owners: existing partners purchase the units in proportion to their holdings or by agreement
- New physician investors: the center resells the units to incoming surgeons through a syndication
In practice, a buyout may combine these approaches. The center might redeem some units and offer the rest to new surgeons. Our guide to ASC syndication explains how centers sell units to new physicians.
How the Buyout Price Is Determined
The price may be set by a formula in the operating agreement, an independent valuation or negotiation. Formulas written years ago may not reflect the center’s current earnings or market conditions, which can lead to disagreements.
Value is generally influenced by earnings, case volume, payer mix and how dependent the center is on the departing surgeon’s cases. If the retiring partner performed a large share of the center’s procedures, the remaining owners and any lender will want to understand how that volume will be replaced.
Financing Options for an ASC Partner Buyout
Depending on the structure, financing may be arranged at the center level, at the individual level or both.
Center-Level Loans
When the center redeems units, it may borrow to fund the purchase. Lenders typically evaluate the center’s historical cash flow, existing debt, payer mix and physician base. Conventional practice loans may fit established centers with steady earnings, depending on underwriting. In some cases, SBA 7(a) financing may be considered, but eligibility depends on the business, ownership structure, use of proceeds, program rules and lender review.
Individual Loans to Remaining Owners
When partners buy the units directly, each may finance their share personally. These loans resemble buy-in loans and depend on the surgeon’s credit, income and liquidity along with the center’s distribution history. Our article on ASC buy-in financing covers that structure in detail.
Payment Over Time to the Departing Partner
Some operating agreements allow the buyout price to be paid in installments. Lenders and programs may limit how much of a price can be deferred, and a note to the departing partner is typically subordinate to bank debt. A departing surgeon should understand the risk of being paid over time.
What Lenders Focus On
Lenders reviewing a buyout often ask:
- How much of the center’s case volume came from the departing surgeon?
- Which surgeons will absorb that volume, and is there a recruiting plan?
- How will the new debt affect distributions to remaining owners?
- Are there existing loans that require consent to an ownership change?
- Will personal guarantees from the departing partner be released or replaced?
A clear transition plan, including timing and case coverage, can make a request easier for a lender to evaluate. Every loan is subject to approval, and nothing here is a commitment to lend.
Considerations for the Retiring Surgeon
The departing partner has interests of their own. Before agreeing to terms, a retiring surgeon may want to review:
- How the sale of units will be taxed, with guidance from an accountant
- Whether any part of the price will be paid over time, and what security supports those payments
- Whether personal guarantees on center debt will be released at closing
- Any restrictive covenants that apply after the sale, which should be reviewed by counsel because enforceability varies by state
A fair, well-documented process can help preserve relationships among partners who may have worked together for many years.
Planning Before the Buyout Happens
The best buyouts are planned years ahead. Centers can review their operating agreement, update valuation formulas, identify successor surgeons and consider how a buyout would be funded before anyone announces retirement.
Founding surgeons who want to step back gradually may also consider selling units in stages. Our guide to ASC succession planning walks through options for founding surgeon-owners, and our advisory and consulting services can help owners think through valuation and transition questions.
Final Thoughts
An ASC partner buyout is one of the most important transitions a surgery center will face. A clear operating agreement, a realistic price, a plan to replace the departing surgeon’s cases and a financing structure the center can support will help protect both the retiring partner and the owners who remain.
