How Private Equity Firms Value Small Businesses

How Private Equity Firms Value Small Businesses

Private equity firms value small businesses using a disciplined, multi-stage framework built around adjusted EBITDA multiples, risk-adjusted cash flow projections, and platform-versus-add-on positioning. For most lower middle market deals ($1M to $10M in EBITDA), private equity firms apply multiples ranging from 4.0x to 8.0x adjusted EBITDA, with the exact multiple driven by industry, growth rate, recurring revenue mix, and owner dependency. Unlike strategic buyers who pay for synergies or individual operators who focus on Seller's Discretionary Earnings, private equity values your business on standalone cash flow after management replacement costs are fully factored in.

If you are preparing for a PE exit, understanding their valuation process is essential. The rest of this guide breaks down exactly how PE firms arrive at their offer — and how you can position your business to command the highest multiple. Start with our business valuation platform to benchmark your company against PE buyer criteria, or see our companion post on what all business buyers look for to understand how PE differs from strategic and individual acquirers.

What PE Firms Calculate First: Adjusted EBITDA

Every PE valuation begins with adjusted EBITDA — not SDE, not revenue. Adjusted EBITDA is your earnings before interest, taxes, depreciation, and amortization, recalibrated to reflect what the business would earn under professional management. Key adjustments include:

• Owner compensation normalization — Replace the owner's salary with market-rate management compensation, typically $150K to $250K for a general manager role
• One-time expense removal — Legal fees for the sale, personal expenses run through the business, and non-recurring costs are added back
• Related-party adjustments — Rent paid to an owner-affiliated entity is adjusted to market rent
• Working capital normalization — A peg is set so the buyer inherits a reasonable level of AR, AP, and inventory

For detailed mechanics on how adjusted EBITDA differs from Seller's Discretionary Earnings, read our complete SDE vs EBITDA guide. The distinction matters: PE firms always value on EBITDA, while buyers of businesses under $1M in earnings typically use SDE.

How the Multiple Gets Set

Once adjusted EBITDA is locked in, the PE firm assigns a multiple based on nine factors:

• Industry sector — Healthcare services (7x to 10x), SaaS (8x to 15x), manufacturing (5x to 7x), home services (4x to 6x)
• Recurring revenue percentage — Businesses with 60% or more recurring revenue command a 1.0x to 2.0x premium
• Growth rate — Companies growing 20% or more annually earn multiple expansion
• Customer concentration — No customer over 10% of revenue is ideal; over 20% creates a meaningful discount
• Management depth — A full management team adds 0.5x to 1.0x; owner-dependent businesses lose 1.0x or more
• Size of EBITDA — Companies with $3M or more in EBITDA earn better multiples than those with $1M
• Industry consolidation trend — Sectors with active rollups pay premiums
• Margin profile — Above-industry-average margins suggest pricing power and operational efficiency
• Geographic footprint — Multi-state or regional presence is more valuable than a single location

Example: HVAC Company Valuation

Consider a residential HVAC company with the following profile:

• Revenue: $8.2M (growing 12% annually)
• Adjusted EBITDA: $1.4M (17% margin)
• Recurring revenue: 35% (maintenance contracts)
• Top customer: 6% of revenue
• General manager in place earning $180K
• Three-state operating footprint

A PE firm would likely value this business at 5.5x to 6.5x adjusted EBITDA — a range of $7.7M to $9.1M. The growth rate, recurring revenue, low customer concentration, and installed management team all push the multiple toward the top of the range. If the owner still ran daily operations with no GM in place, the multiple would likely drop to 4.0x to 4.5x, or $5.6M to $6.3M — a $2M to $3M swing in enterprise value driven by a single structural factor.

Platform vs Add-On Valuations

PE firms bucket acquisitions into two categories with different pricing logic.

Platform acquisitions are the cornerstone of a new investment thesis. These are typically larger businesses ($5M or more in EBITDA) with strong management that will serve as the base for future tuck-in acquisitions. Platforms command premium multiples — often 7x to 10x — because the PE firm is buying a strategic foundation, not just cash flow.

Add-on acquisitions are smaller businesses bolted onto an existing platform. These trade at lower multiples (typically 4x to 5.5x) because the PE firm is paying only for financial value, not strategic positioning. However, add-ons benefit from "multiple arbitrage" — the PE firm buys at a lower multiple and gets credit for the higher platform multiple when the combined entity sells in year 5 or 6.

Valuation Impact: The Owner Dependency Discount

The single biggest multiple killer in PE deals is owner dependency. If the business cannot operate without the founder for 30 days, PE firms apply a 1.0x to 1.5x discount against the baseline multiple. On a business with $2M in adjusted EBITDA, that is a $2M to $3M reduction in enterprise value — often more than a decade of the owner's take-home pay.

The fix is structural, not cosmetic. PE firms can tell within the first management meeting whether the GM is actually running the business or is a figurehead. Installing a general manager 18 to 24 months pre-sale, giving them real P&L authority, and then genuinely stepping back is what unlocks the top of the multiple range.

Exit Implications for Sellers

If you are selling to PE, four actions directly increase your multiple in the 12 to 24 months before sale:

• Install a general manager. A capable GM earning $150K to $250K instantly removes the owner-dependency discount and can add $1M or more to your valuation
• Build recurring revenue. Every percentage point of recurring revenue adds to your multiple; crossing the 50% threshold is a significant step-change
• Invest in Quality of Earnings preparation. Commission a sell-side QofE report 6 months before going to market to preempt the 5% to 10% price reduction that typically comes from buyer-side diligence surprises
• Diversify the customer base. If any customer exceeds 15% of revenue, work aggressively to add accounts or restructure revenue before going to market

PE firms move quickly on well-prepared businesses and grind hard on sellers with messy financials or concentrated risk. The businesses that sell at top-of-range multiples are the ones where the seller has already done the work a PE operating partner would do in year one.
