How to Underwrite a Medical Spa or Aesthetics Practice

Underwrite a medical spa by breaking revenue into injectables, energy device treatments, memberships and retail, then measuring how much depends on individual injectors and whether the ownership structure complies with state medical practice rules. The key metrics are revenue per provider, repeat patient rate, membership revenue, and EBITDA after device lease payments.

What makes medical spa underwriting different

A medical spa sells elective cosmetic treatments such as neurotoxin and filler injections, laser and energy-based procedures, body contouring and skin care. Revenue is cash pay and discretionary, so it tracks consumer spending. Injectors, often nurse practitioners, physician assistants or nurses, build personal followings, and patients may follow a favorite injector to a competitor. Many states restrict who can own a medical practice, so med spas often use management services organization structures with a physician owner of the clinical entity. Expensive lasers and devices are commonly leased or financed and can become outdated as new technology arrives. Promotions and package sales create deferred revenue.

Lenders are cautious with med spas because revenue is discretionary, provider-dependent and the regulatory structure must be correct for the business to operate legally. They focus on historical cash flow, repeat patient metrics, device obligations and compliance with state rules on supervision and delegation. Equity investors and consolidators see high margins and recurring injectable demand, and they pay for multi-location brands with membership programs and diversified providers. Equity may tolerate provider risk with retention equity, while a lender wants structural protections and conservative sizing.

Key metrics

How to underwrite it, step by step

1. Separate revenue by treatment category, provider and new versus returning patients.
2. Review the corporate structure, medical director agreement and supervision arrangements under state law.
3. Measure deferred revenue from packages, gift cards and memberships.
4. List all devices with lease terms, payments and remaining life.
5. Assess provider employment agreements, compensation and non-solicit provisions.
6. Review adverse event history, malpractice coverage and consent forms.
7. Normalize EBITDA and size debt after device payments and deferred revenue obligations.

Due diligence checklist

• Revenue by service, provider and patient type
• Patient visit and retention reports
• Membership and package sales records
• Deferred revenue schedule
• Management services and medical director agreements
• Provider licenses and employment agreements
• Device leases and equipment list
• Malpractice insurance and claims history
• Adverse event logs and consent forms
• Supplier agreements for injectables
• Three years of tax returns and P&L

Key risks and mitigants

Typical financing and deal structure

Medical spa acquisitions are often financed with SBA 7(a) loans when the business and ownership structure qualify, alongside seller notes. Devices are typically financed separately through equipment leases or loans. Consolidators backed by private equity use senior or unitranche debt and frequently structure deals with rollover equity for founders and key injectors. Because state rules can require a physician to own the clinical entity, lenders look at the management services agreement and how cash flows to the borrower. Covenants generally include leverage and fixed charge coverage tests, and purchase agreements often adjust for deferred package revenue.

Red flags

• Ownership structure that may violate state medical practice laws.
• One injector accounts for most revenue and has no agreement.
• Large deferred package revenue with heavy discounting.
• Recent adverse events or regulatory complaints.
• Devices under lease near obsolescence with low utilization.
