What is a PE rollup (and what does it mean for your business)?

A PE rollup is a strategy where a private equity firm buys many similar businesses, combines them into one larger company called a platform, and then sells the whole platform to a bigger buyer at a higher price. If a PE firm is calling you, there’s a good chance they want your business as one piece of that puzzle.

That’s what a rollup is. What it means for you as the owner is a different question, and one worth answering carefully.

Key Takeaways

• A PE rollup buys many similar businesses, combines them, and sells the platform at a higher multiple than any single business would fetch alone.
• PE add-on acquisitions in HVAC rose 88% year over year through June 2025 (PitchBook), so rollup activity in the trades is not slowing down.
• Multiple arbitrage is the core of the strategy: buying at 4x EBITDA and selling at 7x is how PE firms make money, not by running your business.
• You’re either the platform (the anchor business) or an add-on. The distinction affects your price and your leverage.
• Rollover equity gives you a stake in the eventual platform sale, the “second bite of the apple,” but your money is illiquid until the PE firm decides to sell.

What is a PE rollup, and how does it work?

PE firms have acquired nearly 800 HVAC, plumbing, and electrical businesses since 2022, according to PitchBook data reported by Marketplace.org in October 2024. The rollup strategy is why: buy many similar businesses individually, operate them under one corporate structure, then sell the combined company at a valuation no single business could achieve alone.

The mechanics are straightforward. A PE firm identifies a fragmented market, one where many smaller operators exist but no dominant player has consolidated them. Residential trades are a textbook example. The firm acquires an anchor business, called the platform, then systematically adds smaller operators around it. After three to five years, the combined platform sells to a larger buyer, often a national home services company or a bigger PE fund, at a substantially higher price per dollar of earnings.

What is multiple arbitrage, and why does it matter to you?

Multiple arbitrage is the financial engine behind every rollup strategy. A business generating $3 million in EBITDA might sell at 4x on its own, producing a $12 million sale price. A platform generating $30 million in EBITDA might sell at 7x, producing $210 million. The math heavily favors the buyer who assembles the platform, not the owners who sold individual pieces into it.

Here’s a concrete illustration of how the gap works. Ten businesses, each with $3 million EBITDA, sell into a rollup at an average of 4x. Total acquisition cost: $120 million. Combined EBITDA: $30 million. Platform sells at 7x: $210 million. The PE firm captures $90 million in value creation from the multiple expansion alone, before counting any actual growth in the underlying businesses.

That gap is not a sign that you’re being cheated. It’s the economic logic of why PE firms do rollups. The PE firm is taking on the risk and complexity of combining ten separate businesses. They’re earning the difference. What matters for you is understanding what portion of that upside, if any, you’re participating in.

If you sold outright for cash and walked away, you received your multiple at close and that’s the full picture. If you kept rollover equity, your retained stake participates in the eventual platform sale at the higher multiple. The second scenario is where owners can capture some of that multiple arbitrage for themselves.

Are you the platform or the add-on?

When a PE firm approaches you, you’re either the platform or an add-on. This distinction changes nearly everything about your negotiation.

The platform business is the anchor. It’s the first significant acquisition in a market, and typically the largest. The platform owner often negotiates a higher multiple, more operational control post-close, and a seat at the table as the PE firm builds around them. The platform owner may also take on a leadership role in the combined entity. If the PE firm describes you as their “flagship acquisition” or “regional hub,” you’re likely being positioned as the platform.

An add-on is a smaller business acquired to fill a geographic gap, add service lines, or increase technician headcount in a market the PE firm already operates in. Add-ons typically sell at lower multiples than the platform. The PE firm has more negotiating leverage because you’re one of many potential candidates. Add-ons are valuable to the rollup strategy, but they’re more interchangeable than the platform business.

Why are trades businesses a rollup target?

HVAC add-on acquisitions rose 88 percent year over year through June 2025, according to PitchBook data cited by CT Acquisitions. The trades are an active rollup market for reasons that are specific and structural, not accidental.

Trades businesses are fragmented. Most markets have dozens of independent operators with no dominant regional company. That fragmentation is what PE firms look for: many buyers with similar economics, no consolidator yet, and customers who need these services regularly. HVAC, plumbing, roofing, and landscaping also generate recurring revenue through service agreements and maintenance contracts, which PE firms value because it makes future cash flows more predictable.

The businesses are also largely owner-dependent, which creates a specific opportunity for PE. When the owner is the business, the valuation is capped because a buyer has to discount for the key-person risk. PE firms buy enough of these businesses that the combined platform is no longer dependent on any single person. That structural change alone supports a higher sale multiple at exit.

In our experience working with trades owners, most don’t realize they’re in a rollup target market until the third or fourth inbound inquiry. By that point, a PE firm may already own multiple businesses in their region. Understanding the rollup dynamic early gives you more time to prepare and more options when you decide to engage.

How to recognize a rollup approach vs. a strategic acquisition

Not every buyer calling you is running a rollup. A strategic acquirer is a competitor or adjacent business that wants to buy yours because of what it actually does, its customer base, its technicians, or its service territory. A PE rollup buyer wants your business as a building block. The distinction shapes the offer and what happens after you sign.

Signs you’re talking to a rollup buyer:

• They reference a “platform” they’re building or expanding.
• They move quickly and have a standard term sheet they use across acquisitions.
• They ask about your management team’s willingness to stay, because they need operators.
• They offer rollover equity and frame it as a partnership opportunity, not just a transaction.
• They mention other businesses they’ve acquired in your trade or nearby markets.

Signs you’re talking to a strategic acquirer:

• They’re a competitor who wants your customer list, routes, or technicians.
• They have a specific operational reason for wanting your business, not just its revenue.
• The deal is structured as a straightforward purchase with no rollover equity.
• They’re not interested in you staying on after close.

Neither type of buyer is automatically better. A strategic acquirer may pay more because your business is uniquely valuable to them. A rollup buyer may offer a path to a second payout through rollover equity that a strategic acquirer won’t. What matters is knowing which you’re dealing with before you negotiate.

Rollup buyers in the trades often approach owners before those owners are formally on the market. An unsolicited inbound call from a “regional home services platform” is almost always a rollup buyer. That’s not a complaint. It means the market is paying attention to quality businesses. But it also means you’re negotiating without preparation while they have done dozens of these deals. Get an independent valuation first.

Questions to ask a PE buyer about their rollup strategy

When a PE firm calls you, they know the rollup playbook well. You should too. These questions cut through the pitch and give you information that actually matters.

About the platform:

• How many businesses have you acquired in this trade so far?
• What is your current combined revenue and EBITDA across the platform?
• Are you looking for a platform business or an add-on?

About the exit:

• What is your target hold period?
• What type of buyer do you expect to sell the platform to?
• What multiple are you projecting for the eventual platform sale?

About the deal:

• What percentage of the purchase price would be cash at close, and what would be rollover equity?
• What valuation methodology are you applying to my business?
• Have you acquired businesses similar to mine in other markets? Can I speak with those owners?

That last question matters most. A PE firm that has done ten rollup acquisitions in the trades has owners you can call. Those conversations will tell you more than the firm’s pitch deck ever will. For a broader framework, see how to know if a buyer is actually the right fit.

What is the second bite of the apple?

“The second bite of the apple” means the second payout you receive when the PE firm sells the combined platform, assuming you retained a stake in the business at closing rather than taking all cash. It’s the mechanism that gives sellers a way to share in the multiple arbitrage instead of handing it entirely to the PE firm.

Here’s how it works in practice. You sell 80 percent of your business at close and retain 20 percent as rollover equity. The PE firm builds the platform over four years, adds ten more businesses, and sells the combined entity to a national home services company at a 7x multiple. Your 20 percent stake, now a much smaller slice of a much larger company, pays out at that exit. If the platform grew substantially and the multiple expanded, that payout can exceed your original closing proceeds.

Retained minority stakes in PE-backed platforms can return 2 to 4 times their paper value at the next exit, according to Axial.net data on lower middle market transactions. That range reflects the difference between platforms that executed well and those that struggled.

The downside: your money is illiquid from the moment you sign until the PE firm decides to sell. That can be three years or seven. You have no vote on the timing. If you need access to capital, or if you’re planning to retire and want predictable income, keeping illiquid equity in a PE platform introduces real risk.

Common questions owners ask

How do I know if a PE buyer wants me as a platform or an add-on?

Ask them directly: are you building a platform or adding to an existing one? If they already own a company in your trade and your region, you're an add-on. If they're starting fresh and want your business as the anchor, you're the platform. The distinction matters because platform owners typically get higher multiples and more operational control. Add-ons are acquired to fill geographic or service gaps in a portfolio that's already being managed.

What is multiple arbitrage and why does it benefit the PE firm more than me?

Multiple arbitrage is the profit a PE firm makes by buying small companies at low multiples, combining them, and selling the larger platform at a higher multiple. If they buy your $3M EBITDA business at 4x and sell it as part of a $20M EBITDA platform at 7x, the per-dollar gain goes to the firm and its investors, not to you. If you took rollover equity, you participate in that gain on your retained stake. If you sold outright for cash, you don't.

Can I negotiate a higher price knowing I'm part of a rollup strategy?

To a point, yes. If you know the buyer is actively acquiring in your market and has a platform that benefits from your geography or customer base, you have leverage. The PE firm's rollup thesis depends on buying enough add-ons to reach scale. A business that fills a critical gap has more negotiating power than one that's interchangeable with five others in the same market. Get an independent valuation before any conversation.

What is the 'second bite of the apple' and is it worth taking?

The second bite refers to a second payout you receive when the PE firm eventually sells the combined platform, if you kept a stake in the business at closing instead of taking all cash. If the platform sells at a higher multiple than your original deal, your retained stake can be worth more than your initial payout. The risk: your money is illiquid until the PE firm decides to sell, which can take longer than projected. It's worth taking seriously, but not blindly.

How do rollups end, and what happens to my business when they do?

Most PE rollups exit in one of three ways: sale to a larger PE firm at a higher multiple, sale to a strategic acquirer such as a national home services company, or an IPO. The hold period is typically 3 to 5 years, though it often runs longer. At exit, your rollover equity pays out if you retained a stake. Your business, brand, and employees are then owned by whoever the new buyer is. Local branding may be absorbed into a national brand at that stage.
