How to Underwrite a Wholesale Distribution Business

Underwrite a wholesale distributor by analyzing gross margin including supplier rebates, the cash conversion cycle, and dependence on key supplier line cards and customers, then size debt on EBITDA and a borrowing base of receivables and inventory. The metrics that matter most are gross margin stability, inventory turns, days sales outstanding and top supplier share.

What makes wholesale distribution underwriting different

A distributor buys products from manufacturers and resells them to contractors, retailers, manufacturers or institutions, earning a thin gross margin for stocking inventory, extending credit and delivering. The business is working capital intensive: cash is tied up in inventory and receivables, and growth consumes cash. Value often rests on line cards, the rights to distribute specific manufacturers' brands in a territory, which suppliers can revoke or give to competitors. Supplier rebates and volume incentives can make up a meaningful share of gross profit and depend on hitting purchase targets. Customer relationships often sit with outside sales representatives, and price inflation or deflation in the products sold moves revenue and inventory values.

Lenders like distributors as collateral-rich borrowers and often use asset-based revolvers that advance against receivables and inventory, monitored through borrowing base reporting and field exams. Cash flow lenders focus on EBITDA stability and free cash flow after working capital investment. Equity buyers and private equity platforms look for fragmented markets where acquisitions add territories, line cards and purchasing scale, and for margin improvement through pricing tools, private label and warehouse efficiency. Equity may pay for synergies from consolidating branches, while lenders focus on whether supplier relationships and rebates survive the ownership change.

Key metrics

Gross margin including rebates

Rebates can be a large part of gross profit and may be at risk if purchase volumes fall or programs change.

Inventory turns

Shows how efficiently inventory is converted to sales and exposes slow-moving or obsolete stock.

Days sales outstanding

Distributors extend credit to customers, so collection speed drives liquidity.

Cash conversion cycle

Combines inventory, receivables and payables days to show how much cash growth consumes.

Supplier line card concentration

Losing a major line can remove a large share of sales overnight.

Underwriters often scrutinize any single supplier above roughly 20 to 25 percent of purchases.

Borrowing base availability

Eligible receivables and inventory determine revolver capacity.

Asset-based lenders commonly advance around 85 percent of eligible receivables and around 50 to 65 percent of eligible inventory value, often based on appraised liquidation value.

How to underwrite it, step by step

Analyze revenue and gross margin by supplier line, product category, customer and branch.
Quantify supplier rebates, the targets required to earn them, and timing of payment.
Review distribution agreements for territory, exclusivity, termination and change of control terms.
Analyze inventory aging, turns and obsolescence by SKU category and reserve for slow-moving stock.
Analyze receivables aging, credit policy and bad debt history.
Calculate the cash conversion cycle and model working capital needs for growth.
Commission a field exam and inventory appraisal if an asset-based facility is planned.
Size debt using EBITDA and borrowing base capacity and set a working capital peg.

Key risks and mitigants

Supplier terminates a line card or appoints another distributor.

Review agreement terms, contact key suppliers in diligence and stress loss of the largest line.

Rebate income falls if purchase targets are missed.

Separate rebates from base margin and haircut rebates in the downside case.

Obsolete inventory overstates collateral.

Use inventory appraisals, aging analysis and lower advance rates for slow-moving SKUs.

Outside sales reps leave with customer relationships.

Review rep agreements, non-solicits where enforceable and retention incentives.

Product price deflation reduces revenue and inventory values.

Analyze price sensitivity of key categories and monitor inventory valuation.

Typical financing and deal structure

Distributors are commonly financed with asset-based revolving lines secured by receivables and inventory, often paired with a term loan for acquisitions. Cash flow lenders and private credit funds provide senior or unitranche debt for private equity buyouts, sometimes alongside an ABL revolver under an intercreditor agreement. Smaller distributors may use SBA 7(a) loans with a seller note. Supplier consent is often required under distribution agreements, and lenders may condition closing on key supplier approvals. Covenants include fixed charge coverage, leverage limits and borrowing base reporting, with springing covenants common in ABL facilities.

Red flags

A key supplier agreement terminable on short notice or upon change of control.
Rebates making up a large share of gross profit with targets recently missed.
Inventory turns slowing and aged inventory growing.
Receivables from a few large customers aging beyond terms.
Gross margin propped up by one-time price inflation gains.

Frequently asked questions

How are distribution companies valued?

Distributors are typically valued on a multiple of adjusted EBITDA, with buyers paying more for exclusive line cards, diversified customers, specialty products and strong inventory management. Commodity distributors with thin margins and heavy supplier concentration usually see lower multiples. Buyers also consider working capital requirements, since high inventory and receivables needs reduce free cash flow.

What is a line card and why does it matter?

A line card is the list of manufacturers whose products a distributor is authorized to sell, often within a defined territory. Much of a distributor's value depends on these relationships. If a key manufacturer terminates or reassigns the line, sales can drop sharply, so underwriters review agreement terms and supplier relationships carefully.

Why do lenders like asset-based loans for distributors?

Distributors hold large balances of receivables and inventory that can be valued and monitored. Asset-based lenders advance against those assets, providing liquidity that grows with sales. This structure fits the working capital cycle of distribution businesses and can provide more borrowing capacity than cash flow lending alone.

How should supplier rebates be treated in underwriting?

Rebates are real income but depend on meeting purchase volume targets and on supplier programs that can change. Underwriters separate rebates from base gross margin, review program terms and history, and often haircut rebate income in the downside case. Rebate receivables may also receive lower or no advance rate in a borrowing base.
