Profits Interest vs. Equity Interest: What Founders Need to Know Before a PE Deal

Reading Time: 6 minutes

One of the more interesting conversations I have with founders during a transaction has nothing to do with EBITDA, valuation, or even purchase price. It usually starts when the founder says something like this:

“Linda, I have a few key employees who helped me build this company. They’ve been with me for years. I want them to participate in the second bite of the apple after the private equity firm exits.”

That sounds simple enough on the surface. But then the reality of the structure starts to emerge.

If those employees were not already shareholders before closing, they typically cannot simply receive true equity ownership at close without creating a taxable event. In many cases, the founder would effectively need to purchase equity on their behalf or transfer equity with immediate value attached to it. The IRS generally views that as compensation because the employee is receiving ownership in an asset that already has value.

That means taxes may be due immediately, even though the employee may not have received any actual cash to pay those taxes.

Not ideal.

This is exactly why profits interests have become so popular in private equity-backed transactions.

Instead of giving employees ownership in the company’s existing value, buyers often grant profits interests that only participate in future appreciation after the transaction closes. The employees get the opportunity to participate in the upside created going forward, but without the same immediate tax consequences that can come with granting true equity interests.

This is where many founders first realize that not all “equity” is actually the same.

How Traditional Equity Interest Works

Most founders assume equity is equity. If someone owns part of the company after closing, they assume everyone participates equally. In reality, two people sitting next to each other at the closing table may both believe they “have equity,” while having completely different economic rights.

A traditional equity interest gives the holder ownership in the company as it exists today. In partnership taxation, this is often referred to as a capital interest. If the company were sold immediately after that interest was granted, the holder would participate in the company’s current enterprise value.

Let’s say a company is worth $20 million today. If someone owns 10% true equity, they effectively own 10% of today’s value plus 10% of future growth. If the business sold tomorrow for $20 million, that holder would generally expect to receive approximately $2 million.

How Profits Interest Differs From Traditional Equity Interest

A profits interest generally only participates in future appreciation above a certain hurdle value. The holder does not participate in the company’s historical value that existed at the time the interest was granted.

Using the same example, assume the company is worth $20 million today and a manager receives a 10% profits interest with a hurdle value set at $20 million.

If the company sold tomorrow for $20 million, the profits interest holder would likely receive nothing because there was no appreciation above the hurdle. But if the company later sold for $40 million, the first $20 million would go to the original equity holders and the next $20 million of appreciation would be shared according to the profits interest structure. In that scenario, the holder may receive 10% of the growth portion, or roughly $2 million.

Why Private Equity Likes Profit Interests

That distinction matters because, economically, these are very different instruments, even though both may casually be referred to as “equity.”

Private equity firms love profits interests because they align management with future value creation while protecting the buyer’s initial investment. From the PE firm’s perspective, they paid for the company’s current value at closing. What they are willing to share is the upside created after the transaction.

That is why so many PE-backed companies issue:

• profits interests
• incentive units
• growth equity
• sweet equity
• hurdle-based participation units

instead of simply issuing straight common equity.

This also explains why many PE transactions move into LLC holding company structures after closing. Most sellers initially operate as S corporations. But after the acquisition, the buyer often restructures ownership into an LLC taxed as a partnership because partnership structures provide far more flexibility for incentive equity planning.

Inside these LLC structures, buyers can create:

• preferred returns
• custom waterfalls
• hurdle rates
• incentive pools
• catch-up provisions
• IRR thresholds
• MOIC-based payouts

all of which are much more difficult to implement inside an S corporation.

This is why you often see transactions structured with an F-reorganization before closing, followed by a new LLC holding company structure after the acquisition.

Understand What Your “Equity” Actually Is

The important point for founders is this: not all rollover equity participates equally.

A founder may believe they rolled 20% equity into the new company. But part of that “equity” may actually consist of profits interests or subordinate incentive units that only participate after certain thresholds are achieved.

That can dramatically change the economics at the second exit.

This becomes especially important when reviewing:

• LLC agreements
• rollover documents
• management incentive plans
• distribution waterfalls
• recapitalization structures

because the cap table in PE-backed deals can become highly layered.

You may have:

• preferred equity sitting ahead of common equity
• management incentive units only participating after hurdle returns
• vesting requirements tied to continued employment
• sponsor catch-up provisions
• waterfall tiers that change distributions at different exit values

And many founders simply do not spend enough time understanding how these structures actually work.

The tax treatment can differ significantly as well. Properly structured profits interests may allow future appreciation to qualify for capital gains treatment, while phantom equity or bonus-style arrangements often produce ordinary income. On a large exit, that difference alone can easily become a seven-figure tax issue.

The Devil’s In the Details When It Comes to Equity

Most founders spend enormous time negotiating purchase price, EBITDA adjustments, working capital targets, and earnouts. Those things absolutely matter. But many spend surprisingly little time understanding the exact economics of the equity they are receiving after closing.

That can be a mistake because, in many PE-backed transactions, the real wealth creation opportunity is not always the first exit. It is often the second one.

And understanding the difference between a profits interest and a true equity interest is one of the keys to understanding what you are actually receiving at the closing table.

If you are rolling equity into a transaction or negotiating post-close participation for key employees, make sure you fully understand:

• where those units sit in the waterfall
• what hurdle values apply
• whether the participation includes current value or only future appreciation
• how distributions are allocated at the next exit
• and whether the participation is subject to vesting, dilution, or sponsor preferences

Because in private equity transactions, “equity” is not always what it appears to be.

Conclusion

In the end, profits interests can be an incredibly effective tool for rewarding and retaining the employees who helped build the company without creating immediate tax consequences or requiring them to buy into the company’s existing value at closing.

But founders should not assume that all post-close equity structures are created equal. Whether you are rolling equity yourself or helping key managers participate in the next chapter of the business, it is critical to understand exactly what is being granted, how the economics work, where those interests sit in the waterfall, and how future proceeds will actually be distributed.

In many private equity transactions, the second bite of the apple can become more valuable than the first. The founders and management teams who benefit the most are usually the ones who fully understood the structure before signing the documents, not after the next exit occurs.
