ABA deal structures and economics: how transactions are built and priced

The asset purchase

In an asset purchase the buyer acquires selected assets, equipment, contracts, intangible value, and assumes only specified liabilities, leaving the selling entity and its other liabilities behind. This is attractive to buyers on the liability side, because they generally do not inherit unknown or contingent obligations, and on the tax side, because the buyer typically gets a stepped-up basis in the acquired assets. The complication in ABA is regulatory: a Medicaid enrollment, a facility license or certification, and many payer contracts attach to the selling entity and do not automatically come with the assets, so the buyer often must obtain its own enrollment, license, and contracts before it can bill the acquired business. In states where an agency or facility license gates billing, an asset deal can leave a buyer temporarily unable to operate, which is why the timeline must be planned around re-credentialing. Sellers, for their part, may face a less favorable tax outcome in an asset sale than in an equity sale.

The equity purchase

In an equity purchase, a sale of the stock or membership interests, the buyer acquires the entity itself, with everything it holds: its assets, its contracts, its Medicaid enrollment, its licenses, and its liabilities, known and unknown. The regulatory advantage is significant in ABA, because the enrollment, the payer contracts, and the licenses generally continue with the entity, subject to reporting the change of ownership, so the buyer can usually keep billing without rebuilding credentials. The tradeoff is liability: the buyer inherits the entity's history, including any contingent recoupment or compliance exposure, which is why diligence and the compliance representation matter so much. Sellers often prefer equity sales for tax reasons. The recurring pattern across the per-state pages is that equity structures preserve what makes the practice valuable, so they are frequently the cleaner operational choice even when the parties must negotiate harder over liability.

Recapitalizations

A recapitalization is the structure that defines much of the ABA investment market. Instead of selling the whole business, the owner sells a majority stake to an investor and rolls a minority stake into the new ownership structure, remaining an owner and usually continuing to lead the practice. The owner takes significant cash off the table now while retaining equity that can appreciate and be sold again when the investor exits, the so-called second bite of the apple. Recapitalizations align the seller with the buyer through the hold period, which is valuable given how dependent ABA practices are on their clinical leadership, and they are typically built on an equity purchase of the majority interest. The rolled equity is addressed in the rollover section, and some states impose specific rules on covenants tied to minority rollovers, which the relevant state pages flag.

The management-company conversion

In states that restrict who may own a clinical practice, the transaction may be structured as a management arrangement rather than a direct purchase of the clinical entity. The clinical practice remains owned by licensed individuals, while a management services organization, owned by the investor, provides the non-clinical functions, billing, administration, real estate, and human resources, under a management agreement, and the value flows through that agreement. This separates clinical ownership from business ownership to fit ownership and corporate-practice rules. The structure is detailed in the ownership spoke; in a transaction, it matters because the deal may buy or build the management company rather than the clinical entity, and the management agreement, its fee, term, and assignability, becomes a central document. Whether and how this structure is required depends entirely on the state's ownership rules.

Valuation and multiples

ABA practices are generally valued on normalized earnings, an adjusted EBITDA that removes owner-specific and non-recurring items to show the run-rate profitability a buyer would inherit, multiplied by a market multiple. The multiple reflects scale and quality: larger, multi-site platforms with diversified payers, strong compliance, and a defensible clinical model command higher multiples, often in the high single digits to the mid-teens, while smaller single-site practices, add-on acquisitions, command lower multiples. That spread is what drives roll-up strategies, since acquiring smaller practices at lower multiples and folding them into a larger platform valued at a higher multiple creates value through multiple arbitrage. The flight to quality has widened the spread, rewarding clean, well-documented, diversified practices and discounting those with audit exposure or a utilization-maximizing model. These ranges are market context, not a valuation; an actual valuation depends on the specific practice and current market conditions, and is the province of a financial advisor and a quality-of-earnings analysis.

Rollover equity

Rollover equity is the mechanism by which a seller, usually in a recapitalization, reinvests part of the sale proceeds into the buyer's structure rather than taking all cash. The seller ends up holding equity in the larger combined entity, which aligns the seller with the buyer's success and preserves upside through the next sale. Rollover can carry tax-deferral advantages and is a core tool for retaining and motivating the clinical leadership a practice depends on. It also interacts with restrictive-covenant law: because rollover gives the seller an ownership interest, covenants tied to that interest may be analyzed under sale-of-business rather than employment rules, and some states impose specific limits, for example capping the duration of a non-compete against a minority owner who received equity as compensation, which the relevant state pages flag. The structure of the rollover, how much, into what, and on what terms, is a negotiated and advice-intensive part of the deal.

Earnouts and working-capital adjustments

Two mechanisms reconcile the price to reality. An earnout makes part of the purchase price contingent on the business hitting agreed post-closing targets, which bridges a gap between what the seller believes the business is worth and what the buyer will pay up front, and aligns the seller through a transition; in ABA, where revenue depends on retained clinicians and payer relationships, earnouts are common and are often tied to revenue, earnings, or retention. A working-capital adjustment trues up the price at or after closing so the buyer receives an agreed level of working capital, neither over- nor under-funded, with a post-closing reconciliation. Both mechanisms shift risk and reward based on what actually happens after the deal, and both are heavily negotiated, since the definitions and targets determine who captures or bears the post-closing performance.

Escrow, holdbacks, and indemnification

Because diligence prices risk rather than eliminating it, part of the purchase price is typically held back to stand behind the seller's promises. An escrow or holdback sets aside a portion of the price for a defined period to satisfy claims if the seller's representations prove untrue, and indemnification is the contractual obligation under which the seller compensates the buyer for losses from breaches. In ABA, the compliance representation, the seller's statement that it billed in accordance with payer rules, and its indemnity are usually the most negotiated, because the recoupment exposure they back is the deal's central contingent liability. The size and duration of the escrow, the survival period of the representations, and any caps and baskets are calibrated to what diligence found: clean diligence supports a smaller, shorter escrow, while unresolved risk drives a larger, longer one.

Representations, warranties, and insurance

The representations and warranties are the seller's contractual statements about the business, its finances, its compliance, its credentialing, its contracts, and its liabilities, and they are the backbone of risk allocation, because a breach gives the buyer a claim. Increasingly, parties use representations-and-warranties insurance, under which an insurer covers losses from breaches, which can reduce the escrow the seller must post, speed negotiations, and give the buyer a deeper pocket to claim against. Whether insurance is available and economical depends on deal size and the diligence record, a clean, well-documented practice is more insurable, which is another reason sellers invest in sell-side diligence. Together, the representations, the indemnity, the escrow, and any insurance form the system that allocates the residual risk diligence could not remove.

How parties choose a structure

1. Start with what must survive. Identify the enrollment, contracts, and licenses that make the practice valuable, and whether they continue with the entity or must be rebuilt.
2. Weigh liability against operability. Asset deals limit inherited liability but often require re-credentialing; equity deals preserve credentials but carry the entity's history.
3. Layer in tax. Asset and equity structures have different tax outcomes for buyer and seller; the tax advisor models them against the regulatory picture.
4. Decide on alignment. If retaining the clinical leadership matters, a recapitalization with rollover equity and an earnout aligns the seller through the hold period.
5. Fit the ownership rules. In restrictive states, a management-company structure may be required, making the management agreement central.
6. Allocate the residue. Use escrow, indemnification, representations, and insurance to back the promises, sized to what diligence found.

Asset, equity, and recapitalization compared

The right structure depends on the specific practice, the state's change-of-ownership and licensing rules, the tax picture, and the parties' goals, and is determined with counsel and advisors, not from a table.

How this connects to the rest of the guide

Structure and economics sit between diligence and the state overlays:

• Diligence drives the protections. What the due diligence playbook surfaces determines the size of the escrow, the scope of the representations, and the use of earnouts and insurance.
• Private equity uses these tools. The recapitalization, rollover, and multiple-arbitrage mechanics are the engine of the ABA investment market, covered in private equity in ABA.
• Ownership rules shape structure. Whether a management-company structure is required is an ownership question, detailed in the ownership and entity spokes.
• The state pages add the overlays. Whether a given structure preserves enrollment, a license, or a contract, and what change-of-ownership steps apply, is set out on each state's page in the Practice Sale and Expansion spoke.
