The PE Roll-Up Playbook Explained

I've spent the better part of my career watching private equity firms execute the same playbook over and over again. They buy a small business at 4-6x EBITDA, bolt on a handful of similar companies, professionalize the combined entity, and sell the whole thing at 8-12x. The math is elegant, the execution is brutal, and the returns are extraordinary.

If you own a small business in a fragmented industry, there's a good chance a PE-backed platform has already contacted you — or will soon. Understanding how the roll-up playbook works is the single best thing you can do to negotiate a better deal for yourself.

The Multiple Arbitrage: Why Small Companies Sell for Less

The entire roll-up thesis rests on one observable fact: small companies trade at lower multiples than large companies. A plumbing company doing $1.5M EBITDA might sell for 4x. A plumbing platform doing $15M EBITDA sells for 9-10x. Nothing about the underlying plumbing business changed — it's the same trucks, same technicians, same leaky pipes. What changed is the size of the check a buyer needs to write.

This isn't irrational. Larger businesses genuinely deserve higher multiples because they carry less key-person risk, have more diversified revenue, can access cheaper capital, and attract a broader pool of potential buyers. A $15M EBITDA platform can raise institutional debt at SOFR + 300-400bps. A $1.5M EBITDA company is borrowing from a local bank at prime + 2 if they're lucky.

PE firms didn't invent this gap. They just figured out how to monetize it systematically.

Platform vs. Add-On: The Two Phases

Every roll-up starts with a platform acquisition— the anchor company around which everything else gets built. The platform is typically the largest and best-managed business the PE firm can find in the target industry. It's where they install their leadership team, back-office systems, and financial reporting infrastructure.

Platform deals command premium multiples — usually 6-8x EBITDA for a business doing $3-8M EBITDA. The PE firm pays up because the platform sets the ceiling for everything that follows. A sloppy platform means every subsequent integration inherits those problems.

Then come the add-on acquisitions. These are smaller businesses — often $500K-$3M EBITDA — that get bolted onto the platform. Add-ons typically trade at 3.5-5.5x EBITDA, sometimes less. The PE firm is buying revenue, customer relationships, and geographic density. They don't need the add-on's management, accounting, or back-office because the platform already has those.

Here's where the math gets powerful. If a PE firm buys a platform at 7x for $21M (on $3M EBITDA) and bolts on five add-ons at 4.5x for $2.25M each ($500K EBITDA each), they've invested $32.25M for a combined entity doing $5.5M EBITDA. That combined platform, now doing $5.5M, could trade at 8-9x, making it worth $44-50M. The value creation from multiple arbitrage alone is $12-18M.

What Makes a Good Roll-Up Industry

Not every industry lends itself to roll-ups. Having worked on both sides of these deals, I can tell you the PE firms are looking for a very specific set of characteristics.

• Fragmentation: Thousands of small operators and no single player with more than 5% market share. HVAC, plumbing, dental, veterinary, insurance agencies, and home care all fit perfectly.
• Recurring or repeat revenue: Businesses with ongoing service contracts, maintenance agreements, or habitual customers are ideal. An HVAC company with 3,000 maintenance contracts is far more valuable than one doing purely break-fix work.
• Local service delivery: Customers buy based on proximity and trust, which creates natural geographic moats and makes it easy to grow by acquiring in adjacent markets.
• Low technology disruption risk: PE firms want to hold for 5-7 years. Industries where technology might fundamentally change the delivery model are too risky.
• Aging ownership demographics: When 60% of owners in an industry are over 55 with no succession plan, the deal pipeline practically fills itself.

The Roll-Up in Practice: Industry Examples

HVAC and Home Services

Home services may be the most active roll-up sector in the country right now. Firms like Apex Service Partners, Wrench Group, and Installed Building Products have assembled hundreds of HVAC, plumbing, and electrical companies. The thesis is simple: homeowners need their AC fixed regardless of the economy, technicians are the scarce resource (not customers), and adding a plumbing line to an existing HVAC platform costs almost nothing in overhead.

I've seen HVAC companies with $800K-$1.2M EBITDA consistently sell to platforms at 4.5-5.5x. The platform operators know exactly what they're buying and can close in 60-90 days.

Dental and Veterinary

DSOs (dental service organizations) and veterinary consolidators like Mars Veterinary Health, NVA, and Aspen Dental have been rolling up practices for over a decade. The playbook is well-established: acquire practices at 5-7x EBITDA, centralize billing, procurement, and HR, and exit the platform at 10-14x. In veterinary, the multiples have compressed slightly from their 2021-2022 peak, but the consolidation wave continues.

Insurance Agencies

Insurance distribution is arguably the perfect roll-up industry. Revenue is recurring (policies renew annually), customer retention rates are 90%+, and the industry is absurdly fragmented — over 36,000 independent agencies in the U.S. Players like Acrisure, Hub International, and Patriot Growth have built billion-dollar platforms through aggressive acquisition. Agency sellers have seen multiples expand from 6-8x to 10-14x revenue over the past five years as competition among consolidators intensified.

Why Sellers Should Care About the Playbook

Understanding how PE roll-ups work gives you enormous leverage in negotiations. Here's what I tell every owner who gets approached by a PE-backed platform.

Know whether you're a platform or an add-on.If you're the largest operator in your market with strong management and clean financials, you might be a platform candidate. That's a 6-8x conversation, not a 4-5x conversation. Don't let a buyer treat you as an add-on if you have platform characteristics.

Understand the buyer's math.When a PE firm offers you 5x EBITDA for your $2M EBITDA business ($10M), they're planning to sell the combined platform at 9-10x. Your $2M EBITDA is worth $18-20M to them in their exit scenario. That doesn't mean you should demand $18M, but it means the buyer has significant room between their purchase price and their expected return.

Create competitive tension. In most fragmented industries, there are 3-5 active PE-backed platforms competing for add-ons. If one platform has contacted you, the others want you too. Running a structured process — even an informal one — can add 1-2 turns of multiple.

The Risks for Sellers: What Nobody Tells You

For all the upside, selling to a PE roll-up carries real risks that I've seen burn sellers who weren't prepared.

Earn-outs are the norm, not the exception. Most PE add-on deals structure 20-40% of the purchase price as an earn-out tied to revenue or EBITDA targets over 2-3 years. In my experience, roughly 60% of sellers achieve their full earn-out. The other 40% either miss targets because the integration disrupted their business, or they disagree with the buyer's accounting of what counts toward the earn-out pool.

Management changes can be swift and painful. You may have been told your team is critical to the acquisition, but PE firms optimize for the platform, not individual add-ons. Your office manager of 15 years may be replaced by a regional director. Your local vendors may be swapped for national contracts. These changes often improve profitability but can gut the culture you built.

Rollover equity is a double-edged sword.PE firms often ask sellers to reinvest 10-30% of their proceeds into the combined platform. The pitch is compelling — "your second bite of the apple will be bigger than the first." And sometimes it is. But you're now a minority investor in a leveraged entity with no liquidity, no control over capital allocation, and a timeline dictated by the PE fund's lifecycle.

The 5-7 year hold period matters.PE funds typically hold portfolio companies for 5-7 years before seeking an exit. If the market turns, if interest rates spike, or if the PE firm encounters problems in the portfolio, your rollover equity could be worth less than you invested. I've seen it happen — particularly with platforms that levered up aggressively during the low-rate environment of 2020-2021.

How to Position Yourself for Maximum Value

If you think a PE roll-up is in your future — and in many fragmented industries it is — start preparing now.

• Build recurring revenue.Service contracts, maintenance agreements, and subscription models all increase your attractiveness as a roll-up target. Every dollar of recurring revenue is worth 2-3x what a dollar of project revenue is worth in a PE buyer's model.
• Reduce owner dependency.Install a management layer between you and daily operations. PE firms discount heavily for businesses that can't function without the owner.
• Clean up your financials.PE firms and their lenders want GAAP-compliant or at minimum well-organized financials with clear add-backs. Messy books don't kill deals, but they cost you turns of multiple.
• Grow into a platform. If you can get above $3M EBITDA through organic growth or your own small acquisitions, you become a platform candidate rather than an add-on. The difference can be 2-4 additional turns of multiple.
• Hire an advisor who knows PE.A generalist business broker won't get you the same result as an M&A advisor who works with PE firms regularly and understands the roll-up math.

The Bottom Line

The PE roll-up playbook is not going away. If anything, it's accelerating — there are more PE firms, more committed capital, and more fragmented industries left to consolidate than ever before. As a business owner, you have two choices: sell without understanding the game and accept whatever offer lands in your inbox, or learn the playbook, position your business accordingly, and negotiate from a place of knowledge. Having worked with sellers on both sides of that divide, I can tell you the financial outcomes are dramatically different.
