EBITDA
Earnings Before Interest, Taxes, Depreciation, and Amortization — the most common measure of operating profitability used to value businesses in M&A transactions.
Full Definition
EBITDA strips out the effects of financing decisions (interest), tax structure (taxes), and non-cash accounting (depreciation and amortization) to show what the business earns from operations. The formula: Net Income + Interest Expense + Tax Expense + Depreciation + Amortization. An equivalent calculation works up from revenue: Revenue − COGS − Operating Expenses + Depreciation included in above (add back).
How it actually works: In SMB and lower-middle-market M&A, enterprise value is almost always expressed as a multiple of EBITDA. A "5x EBITDA deal" on a company with $3M EBITDA means $15M enterprise value. EBITDA is used because it's roughly comparable across companies with different capital structures, tax situations, and accounting policies — two otherwise-identical businesses with different debt levels or depreciation schedules will have different net incomes but similar EBITDAs. It's also a rough proxy for operating cash flow, which is what buyers are really buying.
EBITDA is widely criticized (most famously by Warren Buffett and Charlie Munger) because it ignores real cash costs like maintenance capital expenditures and working capital investment. For capital-intensive businesses or businesses with working capital growth, EBITDA can meaningfully overstate cash available to investors. Sophisticated buyers adjust by looking at "EBITDA less maintenance CapEx" or free cash flow.
In practice, the EBITDA used in deal pricing is almost never reported EBITDA — it's Adjusted EBITDA, which normalizes for owner-specific and non-recurring items.
Seller vs. Buyer Perspective
Your reported EBITDA probably understates the business's earning power. Most SMB owners run personal and discretionary expenses through the business, pay themselves above market, and have one-time expenses in most years. The Adjusted EBITDA walk — taking reported EBITDA to normalized — is where you'll capture most of your price. Focus on: owner compensation adjustments, personal expenses, one-time items, and discontinued lines. If your reported EBITDA is $2.5M but your adjusted is $3.5M, a 5x multiple means $5M more in purchase price. Hire a sell-side QoE to document this rigorously.
Reported EBITDA is the starting point, not the ending point. Your job in diligence is to challenge every add-back the seller proposes and arrive at a defensible Adjusted EBITDA figure. Also look past EBITDA to cash conversion: what's the maintenance CapEx? What's the working capital need as the business grows? EBITDA minus these items is what you'll actually have to service debt and pay distributions. Capital-intensive businesses — trucking, manufacturing, hospitality — often have "EBITDA less maintenance CapEx" that's 40–60% of EBITDA.
Real-World Example
A pet care services business reports the following P&L: Revenue $8.2M, COGS $3.1M, Operating Expenses $4.0M, Depreciation $280K, Interest Expense $120K, Tax Expense $140K, Net Income $560K. Reported EBITDA: $560K + $120K + $140K + $280K = $1.1M. The owner takes $380K W-2 (market rate for the role is $150K), runs $85K of personal expenses through the business, and has $65K in one-time legal fees from a 2023 contract dispute. Adjusted EBITDA: $1.1M + $230K + $85K + $65K = $1.48M. At a 4.5x multiple, reported EBITDA would suggest a $4.95M price; adjusted EBITDA suggests $6.66M. The $1.7M difference is the entire value of the sale process and the QoE analysis. Deal closes at $6.4M after buyer rejects $75K of the proposed add-backs.
Why It Matters & Common Pitfalls
- !EBITDA isn't cash flow. Maintenance CapEx, working capital, and taxes all take cash that EBITDA ignores. For asset-heavy businesses, this matters a lot.
- !EBITDA can be manipulated. Capitalizing what should be expensed, deferring maintenance, and aggressive revenue timing all inflate EBITDA without changing economics.
- !TTM vs fiscal year. Deals typically value on trailing-twelve-month (TTM) EBITDA, not fiscal year. A business with strong recent momentum wants TTM; a business that just had a big one-time win might not.
- !Pro-forma adjustments. Annualizing recent improvements ("we just hired a salesperson who booked $800K in Q4") is legitimate but controversial. Get these adjustments agreed in the LOI.
- !Industry norms vary. SaaS businesses are often valued on revenue multiples, not EBITDA, because they sacrifice EBITDA for growth. Home services are almost always EBITDA. Know your industry's convention.

Related Terms
Adjusted EBITDA
EBITDA recalculated to remove one-time, non-recurring, or owner-specific expenses so buyers can see the true recurring earnings power of a business.
Add-back
An expense added to reported earnings to arrive at Adjusted EBITDA — reflecting a cost that is owner-specific, non-recurring, or otherwise wouldn't continue under new ownership.
SDE (Seller's Discretionary Earnings)
EBITDA plus owner's total compensation and discretionary benefits — the primary earnings measure used to value owner-operated small businesses (typically under $1-2M of SDE), where the owner's compensation is material to profit.
Valuation Multiple
The ratio between enterprise value and a financial metric — typically EBITDA — used to express what a business is worth in comparable terms. The primary language of SMB/LMM M&A pricing.
Free Cash Flow (FCF)
Cash generated by a business after operating expenses, taxes, and capital expenditures — the actual cash available for debt service, distributions to owners, or reinvestment. FCF = EBITDA − Taxes − Interest − CapEx − Changes in Working Capital. In M&A, FCF is the economic reality check on EBITDA: a business with $5M EBITDA but $2M of maintenance CapEx and $500K working capital needs generates $2.5M of FCF — meaningfully less than EBITDA implies. DSCR calculations use FCF, not EBITDA.
