Rolling twenty percent is not keeping twenty percent of your company.

What is rollover equity?

It is the part of the price a seller takes in shares of the buyer's new holding company rather than in cash. A buyer offering to acquire the business will often ask the owner to reinvest a portion of the proceeds, commonly between ten and thirty percent, into the vehicle that now owns it.

Both sides have a reason to want it. The buyer keeps the owner economically committed to a business whose performance depends on them, and reduces the equity it has to fund itself. The seller keeps exposure to an outcome they believe in and defers the tax on the rolled portion, which we come to below.

What makes it worth an article of its own is that the instrument is routinely described as retaining a stake, and it is not that. The original business no longer exists as an independent entity. What the seller holds is a minority interest in a new company that owns the old one, that carries acquisition debt the old one did not, and whose constitution was drafted for the majority holder.

What do you actually own?

A minority position behind the debt. The holding company that acquires a middle-market business is levered, and the equity in it, including the rolled portion, sits behind every dollar of that leverage. Total debt currently clears at 4.00 to 5.50 times EBITDA for a borrower above $10 million of EBITDA and 5.00 to 6.50 times above $25 million (SPP Capital Partners, Market At A Glance, July 2026). The rolled stake is a claim on whatever remains after that.

That leverage is why the arithmetic is asymmetric in both directions. A modest improvement in earnings produces a large gain on the equity, which is the case the buyer will make and it is a real one. An equivalent deterioration wipes out a large share of the same equity, which is the case nobody makes at the signing dinner. The seller has swapped a whole unlevered business for a slice of a levered one.

It is also a claim exposed to conditions the seller does not control and did not underwrite. Median gross leverage across the middle-market borrower population is 6.1 times and median interest coverage is 1.6 times, and the share of borrowers whose coverage is improving has plateaued after more than two years of gains (KBRA, Q2 2026 Middle Market Compendium, LTM ended 30 June 2026, published 28 July 2026). A rolled stake in a business at those metrics is a leveraged position in a cohort with limited cushion.

And it is illiquid until the majority holder decides otherwise. There is no market for a minority interest in a private holding company, no dividend by right, and no ability to force a sale. The value is realized when the sponsor exits, on the sponsor's timing, or it is not realized.

Which terms decide whether it is worth anything?

Four, and they are settled in the shareholders' agreement rather than in the purchase agreement, which is one reason they get less attention than they deserve. The first is where the rolled shares sit in the structure. Rolling into the same class of ordinary shares the sponsor holds means the seller and the sponsor share the same outcome per share. Rolling into ordinary shares beneath a preferred instrument held by the sponsor means the sponsor is repaid, with an accruing return, before the rolled shares receive anything. Those two arrangements can be described in the same sentence at a meeting and have entirely different results.

The second is drag and tag. A drag-along lets the majority compel the minority into a sale, which the seller should expect and accept; a tag-along lets the minority participate in a sale the majority negotiates, which the seller must have. A structure with the first and not the second allows a sale in which the rolled stake is left behind.

The third is anti-dilution and follow-on funding. If the holding company issues new shares to fund an acquisition or to cure a covenant, a minority holder without pre-emption rights or the capital to participate is diluted, sometimes heavily, in exactly the circumstances where the equity is already impaired. This is the term that most often turns a modest disappointment into a total loss.

The fourth is what happens to the shares if the seller stops working there. Where the rolled equity is subject to leaver provisions, a seller who leaves in circumstances the agreement defines unfavourably can be required to sell at cost or at book rather than at value. Rolled equity that behaves like management incentive equity is not the same instrument as rolled equity that behaves like sale consideration, and the difference belongs on the term sheet rather than in the definitions.

Why is rollover described as tax-efficient?

Because in many structures the seller has received shares rather than cash for the rolled portion, and tax that would otherwise arise on that portion is deferred until the shares are eventually sold. The general shape holds across several jurisdictions; the specific treatment depends on the structure used, the entity types involved, the residence of the seller and the drafting, and it is genuinely easy to lose by accident.

Nothing in this article is tax advice and no seller should proceed on the general shape without their own counsel and accountants confirming the treatment for their circumstances. That is not a formality. The difference between a rollover that qualifies for deferral and one that does not is frequently a drafting choice made for another reason entirely, and it is discovered after signing.

The more important point is what deferral does not mean. Deferring tax is not the same as reducing it, and it is not a reason to roll a larger portion than the seller would otherwise want. A deferral on an amount the seller subsequently loses is worth nothing, and a seller who increased the rolled percentage to improve the tax outcome has paid for that outcome with concentration risk in a leveraged minority position.

Tax is the last input into the rollover decision rather than the first. Size the rollover on what the seller can afford to lose and on the quality of the terms, then structure it so the deferral is available, rather than sizing it to maximize the deferral and accepting whatever terms come with it.

How much should be rolled?

The amount the seller could lose entirely without changing their life. That is a blunt formulation and it is the right one, because the honest description of a rolled stake is a concentrated, illiquid, leveraged position in a single private company, held by someone whose wealth was already concentrated in that company before the sale.

The exit market that has to clear for the second bite to happen is currently narrow. Sponsor-to-sponsor sales fell fifty-seven percent by value in the second quarter of 2026 with the count down thirty-eight percent, the lowest quarterly mark in at least a decade (PitchBook Q2 2026 US PE Breakdown, reported by PitchBook News, 6 July 2026). Private equity funds globally held 32,979 portfolio companies at 31 March 2026 with thirty-four percent held for more than five years, up from twenty-eight percent a year earlier, and at the current pace clearing that inventory would take a near-record nine years (PwC, Global M&A trends in private capital and US Deals 2026 midyear outlook, June 2026).

A rolled stake is a position in that queue. It does not fail because of it, and quality assets do exit, but a seller should price the timing rather than assume it: the second bite arrives when the sponsor can sell, and the published record says selling is currently slower than the fund models assumed.

Two practical tests are worth applying before agreeing a percentage. Would the seller invest the same amount of cash, today, into this specific leveraged holding company on these specific terms, if it were offered as an investment rather than as part of a sale? And does the resulting position leave the seller's total net worth still concentrated in one private business? If the answer to the first is no or the second is yes, the rollover is too large, whatever the buyer's model shows it could be worth.
