Most owners frame the decision as binary. Keep the business or sell it. That framing is understandable. It is also incomplete.
There is a real middle ground that sophisticated operators in MEP, HVAC, and controls are starting to use, and most of the owners who would benefit from it have never had it properly explained to them. Not because it is complicated. Because the people around them have never brought it up.
This post is about that middle ground: what it is, when it makes sense, and when it does not.
What a Partial Sale Actually Is
A minority recapitalization is when an investor, typically a private equity firm or family office, buys a minority stake in your business, usually somewhere in the 20 to 49 percent range, in exchange for cash. You get immediate liquidity. You retain majority control. You stay in the business. The company gains a capitalized partner with resources and often a network you can use.
Nobody is going anywhere.
The distinction from a full sale matters. In a full sale, you hand over the keys. There is a negotiation, a close, a transition period, and eventually you are done. In a minority recap, you take some chips off the table while keeping a meaningful stake in the future value of the business. You have reduced your personal financial concentration. You have created liquidity without creating an exit.
For owners who have most of their net worth tied up in the business, that distinction is significant.
Growth Equity: When the Goal Is Acceleration, Not Just Liquidity
Some investors are not primarily looking to buy into existing cash flow. They are looking to fund a platform strategy: acquisitions, geographic expansion, headcount growth, service line additions. This is growth equity. The owner trades dilution for capital that accelerates the business in ways organic cash flow alone could not.
This structure is common in controls and MEP platforms being actively built out as acquirers. An owner who has a $15 million business and a credible path to $40 million through bolt-on acquisitions has a compelling story to a growth equity investor. The investor brings capital and often operational resources. The owner brings the platform, the relationships, and the execution ability.
The math works differently here than in a standard minority recap. You are not just selling a slice of what exists. You are bringing in a partner to help build what comes next. The dilution is deliberate. The upside, if you execute, is substantially larger than what you would have achieved organically.
Structured Liquidity: The First Bite of a Two-Bite Apple
Sometimes the goal is simpler. The owner wants to diversify personal wealth without fully exiting. A partial sale to a strategic buyer or financial sponsor achieves that. You are not selling the business. You are reducing concentration risk while keeping skin in the game. In deal terms, this is often called the first bite of a two-bite apple.
The logic is straightforward. You have spent 20 years building a business. A meaningful portion of its value exists on paper. A partial sale converts some of that paper wealth into actual liquidity, puts it in your pocket, and lets you retain upside through your remaining stake. When the business eventually sells in full, you collect on that equity a second time.
Owners who have been through this process will tell you that taking the first bite changed how they thought about the business. The financial pressure was off. They could make decisions based on what was right for the company rather than what their personal cash flow situation required.
When This Makes Sense
Partial structures are worth seriously considering when any of the following apply:
- You want liquidity now but are not mentally or operationally ready to fully exit.
- The business is on a strong growth trajectory and you want capital to accelerate rather than waiting to self-fund everything organically.
- Most of your personal net worth is tied up in the business and you want to reduce that concentration without fully exiting.
- You want a partner with institutional resources to help build toward a larger full exit in three to five years.
- You have multiple partners or equity holders who are misaligned on timing and a partial structure creates a path to resolution without forcing a full sale.
The common thread is flexibility. These structures exist because full exits are not always the right tool. When the owner's goals are more nuanced than "I want out," the structure should be too.
When It Does Not Make Sense
This is worth saying plainly because not every situation fits.
- You are mentally done. A partial sale creates a partner relationship that requires ongoing engagement. If you are checked out, burned out, or ready to be finished, a minority recap puts you in a structure where you still have obligations and accountability. Do not do it. If you want out, get all the way out.
- The business is not at a scale that attracts institutional capital. Financial sponsors typically have minimum thresholds for what makes a minority position worth the overhead. If the business is not generating sufficient EBITDA, the universe of investors willing to take a minority stake is small and the terms may not be attractive.
- Valuation expectations are far apart. Minority structures require both sides to agree on what the whole business is worth before calculating what a slice is worth. If the owner's number and the market's number are significantly misaligned, the structure falls apart before it gets to terms.
- You want a clean exit with no residual involvement. If simplicity is the goal, a full sale delivers it. Partial structures are flexible, but they are not simple. There will be a shareholder agreement, reporting requirements, and a real relationship with your investor. For owners who just want a clear close, that complexity may not be worth it.
The Connection to Rolled Equity in Full Sales
Understanding partial structures makes you a better negotiator even when you do plan to do a full sale.
In many PE-backed acquisitions, sellers are asked to roll equity, meaning they reinvest a portion of their sale proceeds back into the new combined entity, typically 10 to 30 percent. This is, structurally, a partial sale. You become a minority partner post-close with skin in the next phase of the business.
Owners who have not thought through minority structures before they get to a full sale often negotiate rolled equity poorly. They treat it as a concession rather than as a value creation opportunity. They accept terms on the rollover without fully understanding what they are agreeing to or what the upside scenario looks like.
Owners who understand how minority economics work go into that negotiation with a clear view of what their rollover stake is worth under different exit scenarios. They know what to ask for, what to push back on, and when the terms reflect actual alignment between buyer and seller. That preparation has a direct impact on outcomes.
Expand How You Think About Your Options
The exit conversation should not start with "do you want to sell or not." It should start with what the ideal outcome looks like for you personally, over what timeframe, and with what level of ongoing involvement.
From there, the right structure reveals itself. Sometimes that is a full sale. Sometimes it is a minority recap with a growth capital partner. Sometimes it is a structured liquidity event that sets up a larger transaction three years from now. The answer depends on the owner, the business, and the goals. Not on a default assumption that there are only two options.
If you are an owner in MEP, HVAC, or controls and you have never had this conversation in a serious way, it is worth having. Understanding what is available to you is the starting point. Everything else follows from there.
