CapEx (Maintenance vs Growth)
Capital expenditure on long-lived assets like equipment, vehicles, and facilities — split between **maintenance CapEx** (what's needed to keep the business running at current levels) and **growth CapEx** (what funds expansion).
Full Definition
CapEx (capital expenditure) is money spent acquiring or improving long-lived assets that get capitalized on the balance sheet rather than expensed on the P&L. In M&A diligence, the crucial question isn't total CapEx — it's the split between maintenance CapEx (necessary to keep the business as-is) and growth CapEx (optional investment that expands capacity, enters new markets, or upgrades beyond replacement).
How it actually works: EBITDA ignores CapEx entirely. But the business's real cash generation is EBITDA minus maintenance CapEx (plus or minus working capital, minus taxes). For an asset-heavy business — trucking, manufacturing, construction equipment, hospitality — maintenance CapEx can consume 20–50% of EBITDA. For an asset-light services business, maintenance CapEx might be 2–5% of EBITDA. These are dramatically different economic realities even at the same EBITDA.
Distinguishing maintenance from growth is judgment. A useful framework: maintenance CapEx is what the business would spend to keep revenue flat and replace assets as they reach the end of useful life. Growth CapEx is the spending above that baseline. Sellers have an incentive to characterize more CapEx as "growth" (since only maintenance reduces the relevant cash flow); buyers have an incentive to characterize more as "maintenance."
Methods for estimating maintenance CapEx in diligence: (1) historical average CapEx over a full business cycle; (2) depreciation as a proxy (rough but often reasonable for steady-state businesses); (3) detailed asset-by-asset replacement schedule; (4) benchmarking against industry norms.
Seller vs. Buyer Perspective
If you're selling an asset-heavy business, be ready for buyers to scrutinize your CapEx. Document which spending was growth (new route, new facility, capacity expansion) vs. replacement (old truck, worn equipment). Segregating these on a schedule helps your case. If your business has deferred maintenance — aging equipment, vehicles at end-of-life, roof that needs replacement — buyers will build a "catch-up capex reserve" into the price, effectively lowering EBITDA. Address deferred maintenance before going to market if possible, or at least document the backlog honestly. Don't claim $0 maintenance CapEx — no asset-heavy business has zero.
Maintenance CapEx is one of the most commonly understated items in SMB diligence. Build a detailed analysis: age of major assets, expected useful lives, replacement costs, annual run-rate. Compare to historical CapEx and depreciation. The gap between seller-claimed maintenance and your calculated maintenance is real dollars — often the equivalent of $100–500K of annual "phantom EBITDA" you'd otherwise pay for at the multiple. In capital-intensive deals, underwrite on EBITDA-less-maintenance-CapEx, not EBITDA. A 5x EBITDA deal in trucking may be a 7–8x multiple on actual cash generation.
Real-World Example
A $2.8M EBITDA regional trucking company has average total CapEx of $1.1M over the past three years. Seller characterizes $900K as "growth" (new tractors added to fleet) and $200K as "maintenance." Depreciation runs $650K. Buy-side analysis reveals the fleet of 28 tractors has average age of 6.5 years against industry useful life of 8 years — implying replacement cycle requires $400K/year of maintenance CapEx minimum. Three of the tractors need major overhauls or replacement within 18 months ($240K). Full maintenance CapEx estimate: $450K/year sustainable, plus $240K catch-up. Buyer treats "true" EBITDA as $2.8M - $450K = $2.35M for valuation purposes, applies a 5x multiple for $11.75M, then deducts $240K for deferred maintenance, arriving at $11.51M. Seller's original pitch was $14M (5x on reported $2.8M). Gap: $2.5M, negotiated to $12.2M close.
Why It Matters & Common Pitfalls
- !Sellers systematically underestimate maintenance CapEx. Especially in family businesses where the owner has run equipment past useful life or deferred maintenance.
- !Depreciation is a rough proxy, not the answer. For steady-state businesses, depreciation approximates maintenance CapEx. For growing or shrinking businesses, it can be misleading.
- !Deferred maintenance is hidden liability. Roofs, HVAC systems, commercial kitchen equipment, vehicle fleets — aging infrastructure comes due eventually. Due diligence should include physical inspection of major assets.
- !Technology capex is often understated. IT systems, software, security — these are easy to defer but expensive when they fail.
- !Real estate CapEx. If the owner also owns the real estate and is paying above- or below-market rent, the building's maintenance CapEx belongs in the post-close analysis (buyer will either buy it or lease at market).
- !The "last year was unusually heavy" argument. Sometimes true, often not. Test against three-to-five year averages.

Related Terms
EBITDA
Earnings Before Interest, Taxes, Depreciation, and Amortization — the most common measure of operating profitability used to value businesses in M&A transactions.
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.
Q of E (Quality of Earnings)
A specialized accounting analysis that validates a target business's reported and adjusted EBITDA, revenue quality, and working capital — typically the primary deliverable of financial due diligence in an SMB/LMM transaction.
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.
Operational Due Diligence
Review of the target company's operations — processes, systems, technology, supply chain, workforce, facilities, and quality controls — assessing operational risks, efficiency, and scalability post-acquisition. Operational diligence goes beyond the financial and legal review to understand how the business actually runs. Key questions: Are systems adequate for the new ownership's reporting needs? Are there operational dependencies on the seller? What infrastructure investment is needed? Can the business scale without major disruption?
