Selling a Distribution Business: How Buyers Model Margins, Inventory, and Working Capital

How buyers model distribution economics: gross margin is the starting point

The first thing a buyer's financial model does with a distribution business is convert top-line revenue into gross profit, not EBITDA. Gross margin percentage is the single most important valuation driver in distribution because it determines how much operating leverage the business can generate, how defensible the revenue is, and how the business compares to peers. Two distributors with identical EBITDA can have very different valuations if one generates it at 35% gross margin and the other at 12%.

The markup vs. margin distinction matters in how distributors describe their economics to buyers. A distributor who prices at "25% markup" is operating at a 20% gross margin (markup is calculated on cost; margin is calculated on revenue). Sellers who present their economics using markup language and buyers who model in margin terms will disagree on the baseline until the terminology is aligned. Prepare a gross margin analysis, revenue minus product cost, before any freight or warehouse costs, at the SKU, product line, and customer level before entering a process.

Inventory: the most common source of purchase price adjustment in distribution deals

Inventory is both the primary working capital asset and the primary diligence risk in distribution M&A. Buyers approach inventory with a specific analytical framework: they want to understand what is turning, what is slow-moving, what is obsolete, and whether the seller's balance sheet reserve reflects economic reality.

Most distribution businesses carry some slow-moving and obsolete inventory that is not fully reserved on the balance sheet. Sellers typically know which SKUs haven't moved in 18 months; the reserve on the books often reflects only a portion of the true write-off exposure. Buyers conduct an inventory aging analysis, stratifying inventory by days-since-last-sale, and apply their own obsolescence assumptions. The difference between the seller's reserve and the buyer's calculation becomes a purchase price adjustment point.

The working capital peg in a distribution transaction is almost always negotiated at a level above "typical" industry norms because distribution businesses hold more inventory than service or technology businesses. The peg calculation should be based on a trailing 12-month average of actual working capital, not a single-date snapshot, and should explicitly address how slow-moving and obsolete inventory is treated in the peg calculation. Sellers who negotiate the inventory treatment in the working capital definition before signing the LOI avoid the most common source of post-close true-up disputes in distribution deals.

The best distribution comps separate product distribution scale from value-added services. SRS is a very large pro-contractor distribution platform, so it should not be used as a direct comp for a $20M specialty distributor, but it is useful evidence of how strategic buyers value branch density, trade-specific purchasing behavior, and professional customer access.

What moves the multiple

The precedent comps are useful context, but buyers do not pay the same multiple for every business in a sector. They adjust valuation based on evidence that the business can sustain earnings, transfer customer relationships, and keep operating without the founder carrying the system personally.

The practical seller objective is not to argue that the company deserves the highest public comp. It is to prove which risks do not apply, which risks have already been fixed, and which operating strengths justify the buyer moving toward the higher end of the relevant range.

Supplier relationships: the most durable value driver in distribution

The defensibility of a distribution business's revenue is determined primarily by its supplier relationships. A distributor who carries commodity lines available through dozens of competitors has no structural advantage; a distributor with exclusive territory rights from a manufacturer, or preferred distributor status in a category with limited authorized channels, controls a revenue stream that is genuinely difficult for a competitor to replicate.

Buyers assess supplier relationships along four dimensions: exclusivity (territorial or category exclusivity), contract terms (duration, renewal rights, termination triggers), assignability (whether the agreement transfers in an M&A transaction), and financial terms (pricing, rebate structure, payment terms). All four dimensions affect how buyers value the business and how they structure the deal.

Supplier rebate programs are a frequently overlooked component of distribution economics. Volume rebates, growth incentives, and co-op advertising reimbursements can represent 1–3% of revenue in some distribution businesses, meaningful relative to overall margins. Buyers want to understand whether rebates are earned on a calendar-year or rolling basis, whether they are at risk in a change-of-control, and whether the new owner will qualify for the same tier. Rebate programs that reset at zero for a new ownership entity are a real economic cost that reduces effective gross margin in the first year of buyer ownership.

Working capital, freight, and the operational data buyers want

Working capital intensity in distribution businesses is structurally higher than in service businesses. A distribution company with $15M in revenue may carry $3–5M in inventory and $2–3M in accounts receivable simultaneously, requiring $5–8M of operating capital. Buyers model this working capital requirement explicitly and factor it into their return calculations, a capital-intensive business requires more equity to operate and therefore generates a lower return at the same EBITDA multiple.

The working capital peg, the baseline level of working capital the seller delivers at closing and the buyer maintains thereafter, is one of the most heavily negotiated items in distribution transactions. It should be set at a level that reflects the normal operating requirements of the business, not the lowest point in the inventory cycle. Distribution sellers frequently want to time a process at the low point of their inventory cycle to reduce the apparent working capital need; sophisticated buyers identify this timing and normalize the peg to a trailing average.

Freight and logistics cost management is increasingly a diligence focus in distribution transactions. Buyers want to understand: how freight costs are recovered from customers (pass-through vs. absorbed), how carrier relationships are managed (negotiated rate contracts vs. spot rates), how fuel surcharges are handled, and whether freight costs have been growing as a percentage of revenue. A distributor who absorbs freight as a margin concession to win volume is operating at a structurally lower effective margin than their reported gross margin suggests.

Positioning a distribution business for sale

The valuation gap between an average distribution business and a well-positioned one is driven primarily by three factors: documented supplier exclusivity, gross margin stratification that shows the defensible portion of the business, and clean inventory data that minimizes diligence uncertainty. All three can be addressed before a process.
