When a private company changes hands, the headline price and the money that actually reaches a diversified bank account are rarely the same figure. A meaningful share of the consideration in lower middle market deals often arrives as something other than cash at closing: equity rolled into the buyer, a promissory note the buyer repays over several years, or an earnout that depends on future performance. Each of these keeps part of the seller's net worth tied to the fortunes of a single company and a single counterparty long after the documents are signed. This article describes those structures and the concentration and illiquidity questions they raise. It is educational and general, and it is not investment, tax, or legal advice, nor a recommendation about what any individual should hold or accept.
Why part of the price is often not cash
Buyers rarely fund an acquisition entirely with cash delivered at the closing table. Non-cash consideration serves several purposes at once. It can bridge a gap between what a seller believes the business is worth and what a buyer will pay in cash today. It can keep a founder financially aligned with the company after the sale. It can allocate the risk of an uncertain forecast to the party best positioned to influence the outcome. Private equity buyers in particular structure deals so that a portion of the purchase price is reinvested, financed, or made contingent. The result is that the cash wire on closing day is one component of the total consideration, and the rest may take years to convert, if it converts at all.
Rollover equity as a concentrated holding
Rollover equity is the portion of sale proceeds a seller reinvests into the buyer or a newly formed holding company rather than receiving as cash. Reported rollover percentages vary widely by deal, commonly cited anywhere from roughly 5 percent to 40 percent of the purchase price, with figures near 20 percent frequently referenced in private equity transactions. The appeal is the prospect of a second bite of the apple: if the sponsor grows the business and sells again in several years, the retained minority stake can generate a further gain. Structured properly, the rolled portion is generally not taxed at closing, with capital gain deferred until the equity is later sold.
The trade-off is that rollover equity is a concentrated, illiquid holding. Common characteristics include:
- Illiquidity. There is typically no public market for a minority stake in a private company, and holders may be locked in for a multi-year investment horizon, often cited in the range of three to seven years, until the sponsor's own exit.
- Minority, non-controlling status. The rolled stake usually carries limited control over strategy, the timing of a future sale, and distributions, which is why negotiated protections such as tag-along rights and information rights are common subjects of the equity documents.
- Transfer restrictions and repurchase rights. Buyback or call provisions can allow the buyer to reacquire the equity on defined terms, and vesting conditions can tie a portion of the stake to continued employment or performance.
- Single-company exposure. The value of the rollover rises and falls with one company's execution, its capital structure, and the sponsor's ability to grow and exit, alongside dilution and share-class priority questions.
Seller notes and single-obligor exposure
A seller note is a promissory note under which the buyer pays part of the purchase price over time, with interest, instead of in cash at closing. For tax purposes this often falls under the installment sale rules. IRS Publication 537 describes the installment method, under which the seller generally recognizes gain as principal payments are received rather than all in the year of sale. A fixed gross profit ratio determines how much of each principal payment is taxable gain, with the balance treated as a return of basis, and the interest component is reported separately as ordinary income.
Several mechanics are worth understanding as general matters of tax law:
- Imputed interest. If the note's stated interest is below the applicable federal rate, the tax rules can impute unstated interest or original issue discount, so a portion of what looks like principal is recharacterized as interest income.
- The pledge rule. For certain larger obligations, using the installment note as loan collateral can be treated as a payment, accelerating gain recognition.
- Default and repossession. Separate rules address what happens if the buyer fails to pay and the seller recovers the business or property.
Beyond tax mechanics, a seller note concentrates single-obligor credit risk. Repayment depends on the ongoing solvency of one buyer and one business, and seller notes are frequently subordinated to a senior lender, meaning they sit behind the bank if cash flow tightens. Unlike a diversified bond portfolio spread across many issuers, the note is a single unsecured or junior claim that cannot easily be sold, and a buyer's stumble can impair or eliminate it.
Earnouts as contingent, unfunded consideration
An earnout makes part of the price contingent on the business hitting defined post-closing milestones, such as revenue or earnings targets over a measurement period. It is not a funded holding at all; it is a promise to pay if performance materializes. Industry data on private-target deals shows why expectations deserve careful calibration. Many deals include no earnout, and among those that do, roughly half see any payment at all outside life sciences. When earnouts do pay, published analyses point to figures around 50 cents on the maximum dollar for paying deals, and closer to 21 cents on the dollar across all earnout deals including those that pay nothing, with life-sciences deals near 19 cents.
Earnouts also concentrate risk in familiar ways. The outcome depends on the same single company, often under new ownership and outside the seller's direct control, and it is exposed to external factors such as regulatory shifts, demand shocks, and competition. Ambiguous milestone definitions are a common source of post-closing disputes over whether a target was met. As a category, an earnout is a contingent, illiquid claim on one business rather than realized, diversifiable value.
How this differs from diversified liquid proceeds
Cash received at closing can, in principle, be deployed across many issuers, sectors, and asset classes, and most of it can be sold on short notice. Rollover equity, seller notes, and earnouts share the opposite profile in different forms:
- Single-issuer or single-obligor concentration. All three tie value to one company and, for notes and earnouts, to one counterparty's willingness and ability to pay.
- Illiquidity. None can be readily sold. A rollover waits for the sponsor's exit, a note pays on its schedule, and an earnout resolves only after the measurement period.
- Contingency and credit risk. A note carries credit risk, an earnout carries performance risk, and a rollover carries both equity and execution risk.
Portfolio diversification is a general finance concept describing the spreading of holdings to reduce exposure to any one asset. Non-cash deal consideration runs against that concept by design, which is why the size and terms of the non-cash portion are often a central negotiation point rather than an afterthought. There is also a timing dimension. Diversified liquid proceeds exist in full on closing day, while rollover value, note principal, and any earnout arrive later and remain exposed to intervening events at the one company that underwrites them. A single downturn, a covenant breach at the buyer's lender, or a missed milestone can affect several of these components at once precisely because they share the same underlying business. How an individual weighs those trade-offs is a matter for that person and their own tax and financial advisors, and the appropriate balance differs with each seller's other assets, income needs, and time horizon.
Where the cash-and-contingent mix takes shape
The proportion of cash to non-cash consideration is not fixed by the market; it is negotiated, and it tends to move with the competitiveness of the process and the quality of the information a seller can present. A well-prepared, competitive sale process gives a seller more leverage to shape that mix and to model the after-tax, risk-adjusted value of each component rather than reacting to a single buyer's proposed structure. Preparation platforms such as Bankerly organize the diligence materials and financial support that let sellers and their advisors evaluate cash, rollover, notes, and earnouts on comparable terms. The structuring itself, and any decision about what to accept, remains work for licensed tax, legal, and financial professionals engaged by the seller.

Frequently asked questions
- What is rollover equity in a business sale?
- Rollover equity is the portion of sale proceeds a seller reinvests into the buyer or a new holding company instead of taking as cash. It is generally tax-deferred until later sold, but it is an illiquid, non-controlling minority stake whose value depends on one company's future performance.
- Is a seller note taxed all at once at closing?
- Often not. Under the installment sale rules described in IRS Publication 537, a seller generally recognizes gain as principal payments are received rather than entirely in the year of sale, with interest reported separately. Specific outcomes depend on the note terms and the taxpayer's situation.
- How often do earnouts actually pay out?
- Published analyses of private-target deals indicate that many deals include no earnout, and among those that do, roughly half pay anything at all outside life sciences. Paying deals average around 50 cents on the maximum dollar, and closer to 21 cents across all earnout deals including non-payers.
- Why are these structures described as concentration risk?
- Rollover equity, seller notes, and earnouts all tie value to a single company and, for notes and earnouts, a single counterparty. That single-issuer or single-obligor exposure, combined with illiquidity, contrasts with cash proceeds that can be spread across many holdings and sold readily.
- Is this article tax or investment advice?
- No. It is general educational information describing how non-cash deal consideration works and the concentration and illiquidity questions it raises. It is not tax, legal, or investment advice, and decisions about deal structure should involve licensed professionals engaged by the seller.
