A $4M business acquisition. Two classes of equity. One operator who thinks they own 25%. Another who actually understands what that means at exit.
Most aspiring search fund operators can quote their equity percentage. Few can explain what happens to it when things go sideways. According to the 2024 Stanford Search Fund Study, 681 search funds have formed in the U.S. and Canada since 1984. Every traditional search fund in that cohort went through the same two-stage capital structure. Most operators still misread it.
Here is how a search fund acquisition entity is actually structured, from the two-stage fundraise to the exit waterfall.
The two-stage fundraise
Traditional search funds raise capital twice. The structure of each round is different. The rights attached to each round are different. Conflating them costs operators real money.
Round one: search capital. The searcher raises $400,000 to $600,000 from 10 to 30 investors, typically $25,000 to $50,000 per unit. This capital covers living expenses, deal sourcing costs, legal work, and overhead during the 18- to 24-month search period. Investors in this round take meaningful risk. The searcher might never find a company worth acquiring. Search capital has a total-loss outcome in roughly 30% of funds.
Round two: acquisition capital. When the searcher finds a target and signs a letter of intent, existing investors get the first call. Pro-rata rights are standard. Investors who backed the searcher in round one have the right to participate in the acquisition financing. New capital fills any remaining gap.
The total equity portion of an acquisition typically represents 30% to 50% of the purchase price. Senior debt covers most of the balance. The exact mix depends on the business's cash flow quality and available lender appetite.
The step-up: how search capital converts
Search stage investors don't simply roll their original capital into the acquisition round at face value. They receive a bonus for the risk they absorbed during the search period.
The mechanism is a step-up, typically 1.5x to 2x. An investor who committed $50,000 in search capital sees that unit convert to acquisition equity worth $75,000 to $100,000. When they write their acquisition round check, their effective price per unit is lower than any new investor coming in at close.
This is not a gift. It is compensation for holding an illiquid, high-risk position for two years while the searcher hunted for a business that might not exist. According to Search Fund Market's equity breakdown, the 1.5x step-up is the community standard, though some structures reach 2x for early or larger commitments.
Preferred equity: who gets paid first
Acquisition capital does not come in as common equity. It comes in as preferred.
Preferred shareholders sit above common equity in the capital stack. They get paid first. That sentence should appear in every operator's notes when they read a term sheet.
The standard terms: investors receive a cumulative preferred dividend in the range of 6% to 8% per year, accruing from the date of acquisition close. They also hold a liquidation preference equal to their total invested capital, which includes the step-up value plus any co-investment. In a sale or liquidation event, preferred holders recover their full capital contribution plus all accrued dividends before a single dollar flows to common shareholders.
Run the math on a three-year hold. A $2M preferred investment at 7% annual cumulative preferred grows the first-out claim to roughly $2.44M before any common equity touches exit proceeds. In a downside scenario where the business sells at or near invested capital, the preferred holders walk away whole. The operator walks away with nothing.
Two structures matter here.
Participating preferred. Investors collect their liquidation preference and then continue to share in remaining proceeds alongside common shareholders on a pro-rata basis. This structure is more investor-friendly. It compresses the operator's effective share of upside in a successful exit.
Non-participating preferred. Investors choose between their liquidation preference or converting to common and sharing proceeds pro-rata. They pick whichever pays more. This structure is more operator-friendly and is the dominant form in U.S. search fund transactions today.
The difference is significant at exit. Know which one you're agreeing to before you sign the term sheet.
Operator equity: the 20% to 30% that vests in three pieces
The searcher's ownership lives in common shares. Solo searchers typically receive 20% to 25% of the acquisition entity. Two-person partnerships often land around 30%, split between both operators. That range reflects community norms more than a formula; the Stanford primer and IESE templates form the baseline most deal attorneys reference.
None of it vests at once. It earns in three tranches:
Acquisition close (roughly one-third). This tranche vests immediately when the deal closes. It rewards the searcher for completing a multi-year search and executing a transaction under real uncertainty.
Time-based (roughly one-third). This portion vests gradually across the operating period, typically two to four years. Operators who exit early forfeit unvested shares. This creates an incentive to stay and operate, not just acquire and flip.
Performance hurdles (roughly one-third). The final tranche vests only if specific return targets are hit, typically tied to investor IRR thresholds at exit. If the business doesn't deliver those returns, this tranche stays with the investors.
The tension in every search fund negotiation is predictable: searchers want more weight on time-based vesting. Investors want more weight on performance. Most deals split it roughly equal. The 1.5x step-up and three-tranche equal vesting have become defaults that most experienced search fund attorneys use as their starting point.
The exit waterfall
The waterfall determines who gets paid, in what order, when the business sells.
First: senior lenders collect their outstanding debt and accrued interest. Search fund acquisitions carry real leverage. The senior debt claim comes before anyone else.
Second: preferred equity holders receive their liquidation preference plus all accrued cumulative dividends. If participating preferred is in place, they then share pro-rata in the remaining proceeds alongside common shareholders.
Third: common shareholders, including the operator and any management equity pool, receive whatever remains.
This ordering explains why two operators can both hold "25% equity" and arrive at completely different outcomes. A business sold for 3x invested equity in a strong exit might produce $5M to $6M in operator proceeds. The same business sold for 1.1x invested equity generates zero in operator proceeds after preferred holders are made whole. The percentage is not the number that matters. The waterfall is.
What the Stanford 2024 data shows
The 2024 Stanford Search Fund Study tracked 681 search funds from 1984 through December 31, 2023. The aggregate investor IRR was 35.1%. The aggregate return on invested capital was 4.5x. These are the numbers the ETA community cites most often.
The operator equity picture is more nuanced. Entrepreneurs who had exited their acquired companies earned an average of $5.7 million in equity value, with a median of $2.25 million. Operators still running their acquired businesses showed an average of $6.09 million in paper equity, median $1.98 million.
Two things to note. Averages in skewed distributions lie. A handful of outlier exits pull the mean up significantly. The median of $2.25 million for exited operators is the more honest benchmark for most searchers to model against. Second, these figures apply only to operators who successfully acquired a company. The roughly 30% of search funds that fail to acquire return nothing.
The distribution of outcomes is wide. Understanding exactly where you sit in the cap table, and under exactly what conditions your equity becomes valuable, is not a legal formality. It is the foundation of any honest financial model.
What operators typically get wrong
The most common mistake is treating the equity percentage as the answer. It is the starting point of a question that ends with the waterfall.
A 25% equity stake in a business acquired at 6x EBITDA with participating preferred and 8% cumulative dividends produces a completely different operator outcome than 25% in a business acquired at 4x EBITDA with non-participating preferred and no accumulated dividend. Same percentage. Different economics.
The second mistake is ignoring the debt load at acquisition. Senior lenders come before everyone. A business that stumbles operationally in year one may spend years generating enough cash flow to service debt, let alone build equity value above the preferred claims. Operators who pressure-test their cap table against downside scenarios, not just base cases, enter negotiations with a clearer picture of what they are actually agreeing to own.
Cap table literacy is the same discipline that governs every high-stakes decision: know exactly what you are walking into before the situation requires you to perform.

If you are evaluating the search fund path, start with the Stanford Search Fund Primer, a qualified M&A attorney who has closed search fund transactions, and a clear model of your exit waterfall across three scenarios: downside, base, and upside. The equity is the reason to do this. The cap table determines whether you actually earn it.
Frequently Asked Questions
What is the step-up mechanism and why do search stage investors receive it?
Search stage investors receive a step-up, typically 1.5x to 2x, when their search capital converts into acquisition equity. An investor who committed $50,000 sees that convert to equity worth $75,000 to $100,000. This compensates them for holding an illiquid, high-risk position during the search period while the operator hunted for a deal.
What is the difference between participating and non-participating preferred equity in a search fund deal?
With participating preferred, investors collect their liquidation preference and then continue to share in remaining proceeds alongside common shareholders. With non-participating preferred, investors choose between their liquidation preference or converting to common, picking whichever pays more. Non-participating preferred is the dominant form in U.S. search fund transactions today.
In what order does money flow out when a search fund company is sold?
Senior lenders collect outstanding debt and accrued interest first. Preferred equity holders then receive their liquidation preference plus all accrued cumulative dividends. Common shareholders, including the operator, receive whatever remains after those two claims are satisfied.
Why can two operators with the same equity percentage end up with very different exit proceeds?
The percentage is not the number that matters. The waterfall determines outcomes. A business sold at 3x invested equity can produce millions for the operator after preferred holders are paid. The same business sold at 1.1x invested equity generates zero for common shareholders once preferred holders are made whole.
