Gross Margin
Revenue minus direct cost of goods sold (COGS), expressed as a percentage of revenue. Gross margin measures the profitability of core product/service delivery before overhead. High gross margins (software: 70-90%, professional services: 50-70%) create more leverage for G&A investment and EBITDA. Low gross margins (distribution: 20-30%, staffing: 15-25%) require operational discipline to generate EBITDA. In M&A, gross margin trends (expanding vs. compressing) signal pricing power and competitive position.
Full Definition
Gross margin is the percentage of revenue remaining after subtracting the cost of goods sold (COGS) or cost of revenue — the direct costs of producing or delivering the product or service. It is calculated as (Revenue − COGS) / Revenue × 100. Gross margin is a fundamental indicator of business economics: how efficiently a company converts revenue into profit before accounting for operating expenses, and how much cushion exists to cover overhead and generate earnings.
What gross margin reveals: A company's gross margin reflects its pricing power, cost structure, and competitive position. High gross margins (software: 70–85%; professional services: 60–75%; SaaS: 70–80%) signal that the business retains most of each revenue dollar to cover operating expenses and generate profit. Low gross margins (distribution: 15–30%; construction: 15–25%; grocery: 20–30%) mean the business must run a very lean operating cost structure or generate high volume to produce meaningful earnings.
Gross margin vs. EBITDA margin: Gross margin is before operating expenses (SG&A, R&D, sales and marketing); EBITDA margin is after operating expenses and before interest, taxes, depreciation, and amortization. A business with 70% gross margin and 20% EBITDA margin is spending 50% of revenue on operating costs — which may be appropriate for a high-growth business investing heavily in sales and R&D, or a sign of operating inefficiency in a mature business.
Gross margin in M&A valuation: Gross margin directly affects the multiple a business commands. Software companies are valued at higher EBITDA multiples than distribution companies because software gross margins of 75%+ allow most revenue growth to flow to the bottom line — operating leverage is high. Distribution companies at 20% gross margins must generate enormous revenue growth just to move the EBITDA needle. Buyers pay for gross margin quality because it represents the ceiling on long-term profitability.
Gross margin improvement as a value creation lever: PE sponsors and strategic acquirers often identify gross margin improvement as a primary post-close value creation opportunity — through pricing increases, supplier renegotiation, product mix optimization, or direct cost reduction. Even a 2–3 percentage point gross margin improvement on $10M revenue can add $200K–$300K to EBITDA, which at a 5x multiple is $1M–$1.5M of enterprise value creation.
Seller vs. Buyer Perspective
Know your gross margin and how it compares to industry peers. If your gross margin is below industry average, expect buyers to apply a lower multiple and potentially model margin improvement as a synergy they pay for partly through price reduction. If your gross margin is above industry average, emphasize what drives it — proprietary sourcing, premium pricing, high-value service content — and build that story into your sale process narrative.
Analyze gross margin by product line, customer segment, and project type — blended gross margins can mask dramatically different economics within a business. A company with 35% blended gross margin may have some products at 60% and others at 15%, with the high-margin products growing and the low-margin products declining. Understanding gross margin composition helps you model realistic post-close outcomes and identify where to focus cost reduction or pricing improvement efforts.
Real-World Example
A specialty chemical distribution company has $12M revenue and 24% gross margin ($2.88M gross profit). Operating expenses (SG&A, salaries) run $1.6M, producing $1.28M EBITDA (10.7% EBITDA margin). A strategic acquirer with an existing supplier relationship believes they can source chemicals at 3% lower cost through their volume purchasing program — improving gross margin to 27%, adding $360K to gross profit and EBITDA. At a 5x multiple, this gross margin improvement alone is worth $1.8M in enterprise value — a meaningful portion of the acquisition rationale.
Why It Matters & Common Pitfalls
- !COGS classification inconsistencies inflate gross margin. Some companies classify costs as operating expenses that others include in COGS (customer success headcount, implementation costs, hosting costs for SaaS). Comparing gross margins across companies requires understanding exactly what each company includes in COGS.
- !Gross margin can be temporarily elevated by favorable input pricing. Commodity-priced input businesses (food, metals, energy) have gross margins that fluctuate with input cost cycles. Model gross margins across a full cycle — not just the current favorable period.
- !Service revenue attached to product revenue distorts gross margin. A product company that bundles high-margin services with lower-margin products may report blended gross margins that are misleading. Separate product and service gross margins in your analysis.
- !Gross margin improvement projections must be operationally specific. Vague statements that 'we can improve gross margin through better procurement' are not investable theses. Identify the specific suppliers, the specific negotiation levers, and the specific contract terms you'd negotiate — then stress-test whether the suppliers would actually agree.

EBITDA Margin
EBITDA expressed as a percentage of revenue — a measure of operating profitability before interest, taxes, depreciation, and amortization. EBITDA margin is a key valuation driver: higher margins indicate more efficient operations and typically command multiple premiums. Industry benchmarks vary widely — professional services 15-30%, distribution 6-12%, SaaS 20-40%, manufacturing 10-20%. Margin trends (expanding vs. contracting) matter as much as absolute level.
EBITDA
Earnings Before Interest, Taxes, Depreciation, and Amortization — the most common measure of operating profitability used to value businesses in M&A transactions.
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.
