How Do Private Equity Firms Value a Company? (And How to Use the Same Playbook Yourself)

Every private equity firm that calls you already knows what your company is worth, roughly, before they ever get on the phone. You don't. That asymmetry is the whole game - and it's fixable in an afternoon.

I've been on both sides of this table on 100+ deals. The valuation methodology PE firms use isn't secret or complicated. It's a repeatable process: start with EBITDA, normalize it, apply a market multiple, and sanity-check the result against comparable deals. Run that same process on your own numbers before you're sitting across from a fund's analyst, and you walk into every conversation - private equity, strategic buyer, or Independent Buyout - knowing your number instead of accepting theirs.

Step 1: Start with EBITDA, not revenue

Private equity firms almost universally price deals off EBITDA - earnings before interest, taxes, depreciation, and amortization - because it strips out financing and accounting choices and shows the cash-generating power of the business itself (Corporate Finance Institute). Revenue tells a buyer how big you are. EBITDA tells them how much cash the business actually throws off, which is what services debt and generates returns.

Step 2: Normalize it - this is where most of the value gets found or lost

Your reported EBITDA is not what a buyer will pay a multiple against. Buyers start with reported EBITDA, then adjust for one-time items and owner-specific costs to arrive at "adjusted" or "normalized" EBITDA - the number the deal actually prices on (Lutz).

Common add-backs include: - Above-market owner compensation. If you pay yourself more than a market-rate professional manager would cost to run the business, the difference is added back (Shepi.ai). - One-time or non-recurring expenses - legal settlements, a one-off equipment failure, transaction costs. - Discretionary or personal expenses run through the business.

This isn't a minor technicality. At a typical lower-middle-market multiple, every $100,000 of successfully defended add-back can translate into $400,000-$700,000 of additional enterprise value - and every add-back a buyer's diligence team rejects gets removed at that same ratio, straight out of your price (Glacier Lake Partners). Owner compensation is the single most commonly challenged add-back in diligence - sellers who lowball the "replacement cost" of their own role routinely give value back at the table (Glacier Lake Partners).

The playbook move here: build your add-back schedule before a buyer's team builds theirs. Know which of your adjustments are genuinely defensible - one-time transaction costs, duplicative compensation, discontinued-operation costs - and which are softer, so nothing in your number surprises you mid-negotiation (LinkedIn / Matteo Chiappini on QoE add-back categories).

Step 3: Get a Quality of Earnings review done on your own terms, first

A Quality of Earnings (QoE) report reconciles your reported EBITDA to what a buyer will consider "true," maintainable EBITDA - stripping out one-time items and stress-testing your add-backs before a deal ever prices (Eternal PE). It is not the same as an audit: an audit asks whether your historical numbers are accurate; a QoE asks whether your earnings are sustainable and actually convert to cash going forward (Human R). That distinction - sustainable, cash-converting earnings - is exactly what a buyer's investment committee is pricing.

Aggressive add-backs are running at an average of 29.4% of management-adjusted EBITDA industry-wide, and diligence teams are rejecting more of them than they used to (Human R, "15 EBITDA Add-Backs PE Firms Accept," 2026 guide). Commission your own QoE before you go to market, and you fix the soft spots in your own numbers while you still control the timeline - instead of finding them out during a live negotiation, when they become the buyer's leverage against you.

Step 4: Apply the market multiple

Once you have a defensible, normalized EBITDA figure, the buyer applies a multiple derived from recent comparable deals - this is where "comps" come in. Two related methods drive the multiple:

• Comparable company analysis looks at the trading or transaction multiples of similar businesses.
• Precedent transaction analysis looks specifically at what buyers actually paid in recent M&A deals for similar companies - and typically runs 15-30% higher than public trading comps, because it captures the control premium a buyer pays to actually own and direct the business, not just hold shares in it (CT Acquisitions).

As of 2025, average lower-middle-market EBITDA multiples held at roughly 7.2x across deals in the $10 million-$500 million enterprise value range, according to GF Data - with meaningful spread by sector: healthcare services near 8.3-8.5x, business services around 7.2-7.4x, manufacturing closer to 6.5-7.0x (CIBC US Middle Market Monitor, Q1 2026; Mid Market Advisory). Size matters too - deals around $20 million in enterprise value have cleared closer to 6.4x, while $150 million deals have cleared closer to 10x (Capital Pad). If you don't know where your sector and size actually sit in that range, you have no way to know if a buyer's opening number is fair or lowball.

The math, in one table

Step	What it is	Why it moves your price
Reported EBITDA	Your P&L's current earnings figure	The unadjusted starting point - not the sale price
Normalized EBITDA	Reported EBITDA + defensible add-backs	Every $100K of defended add-back ≈ $400K-$700K of enterprise value at typical LMM multiples (Glacier Lake Partners)
Quality of Earnings review	Independent test of whether normalized EBITDA is sustainable	Determines how much of your add-back schedule actually survives diligence (Human R)
Market multiple (comps)	Sector/size-adjusted multiple from recent deals	2025 lower-middle-market average ~7.2x EBITDA, varying by sector and size (CIBC)
Enterprise value	Normalized EBITDA × multiple	This is the number a term sheet is actually built around

This table is illustrative - actual multiples and outcomes vary by transaction, sector, and specific deal facts.

Why this same playbook applies to an Independent Buyout

Owners are usually shown two paths for a sale conversation: private equity or a strategic buyer. Both price the deal using exactly the methodology above - normalized EBITDA times a market multiple. What most owners aren't told is that an Independent Buyout, where the company's own leadership team becomes the buyer, is priced the same way. The valuation work doesn't change; what changes is who's on the other side of the table, who finances the purchase, and what happens to control after close.

Running your own EBITDA normalization and comp analysis before any conversation means you show up to a private equity pitch, a strategic buyer's diligence team, or an Independent Buyout structuring conversation already knowing your number - instead of hearing it for the first time from someone whose fund is compensated by getting you to accept less of it, or a broker whose fee only exists if that specific type of deal closes.

Frequently asked questions

Why do private equity firms use EBITDA instead of revenue or net income? EBITDA strips out financing structure, tax situation, and non-cash accounting choices, isolating the cash-generating power of operations - which is what a leveraged buyer actually cares about servicing debt against (Corporate Finance Institute).

What's the single biggest lever an owner controls in their own valuation? The add-back schedule, particularly owner compensation normalization. Building and defending it correctly before a buyer's diligence team builds their own version of it can meaningfully change your final number (Glacier Lake Partners).

Is a Quality of Earnings report the same as an audit? No. An audit verifies historical accuracy under accounting rules. A QoE tests whether your earnings are sustainable and convert to cash going forward - the actual question a buyer's price is based on (Human R).

Do private equity buyers and Independent Buyout structures value a company differently? No - both price off normalized EBITDA and a market-based multiple. The valuation methodology is the same; what differs is the buyer, the financing source, and what happens to control and tax treatment after close.

What EBITDA multiple should I expect for my business? It depends heavily on sector and size. Lower-middle-market deals averaged roughly 7.2x EBITDA in 2025, with healthcare services trading near 8.3x-8.5x and manufacturing closer to 6.5x-7.0x, and larger deals commanding higher multiples than smaller ones (CIBC Q1 2026; Mid Market Advisory).

The bottom line

Private equity firms don't have a secret formula. They have a repeatable process - normalize your EBITDA, apply a defensible market multiple, stress-test it with a Quality of Earnings review - and they run it on your business whether you've run it yourself or not. The only question is whether you know your own number before you sit down, or find it out from someone who's paid more when you accept a lower one.
