Due diligence on a manufacturing business

Financial diligence on a manufacturer follows the same basic pattern as any acquisition — verify revenue, normalize earnings, check the balance sheet. What makes manufacturing different is the list of sector-specific issues sitting behind those numbers: a property that may carry environmental history from decades of industrial use, a tax consequence tied to selling depreciated equipment, inventory that is genuinely hard to value accurately, and sometimes a unionized workforce with its own binding obligations. Missing any of these tends to cost more than a financial modeling error would.

Environmental history is worth checking early, not late

Industrial and manufacturing sites carry a real chance of contamination in the soil or groundwater, sometimes from processes that ran long before the current owner took over and that show up nowhere in the company’s own records. A lender financing the purchase will often require an environmental site assessment before releasing funds, so commissioning one early in diligence gives its findings time to actually shape price or structure, rather than just confirming a problem after it is too late to do much about it. Ask specifically whether any previous environmental orders, spills or remediation work have been recorded against the property, since a clean current appearance does not rule out a documented history the seller may not volunteer unprompted.

Understand the CCA recapture exposure

Selling equipment for more than its remaining balance for tax purposes can trigger recapture, converting part of what feels like a straightforward asset sale into income in the year of sale rather than a capital gain — the second thing that regularly catches manufacturing sellers off guard, and one that shapes whether an asset sale or a share sale ends up being the better fit for a given transaction. Run the actual numbers with an accountant before assuming either structure is obviously right. This is worth doing early enough that it can still influence how the deal is priced and structured, rather than surfacing as an unwelcome surprise in the seller’s tax filing the year after closing.

Verify equipment condition against the appraisal

• Maintenance and repair logs for the major equipment, checked against an independent mechanical inspection
• Age and remaining useful life relative to what the appraisal and the seller’s earnings assume
• Any equipment that is leased or financed rather than owned outright
• Downtime history and any recurring failure patterns on critical machines
• Utility, service and maintenance contracts tied to specific equipment, and whether they are assignable

Count and value the work-in-progress and inventory yourself

Manufacturing balance sheets are prone to inventory and work-in-progress figures that have not been recently or accurately counted, and a buyer’s diligence should include an actual physical count near closing rather than relying on the seller’s stated figures. Any gap between what is on the books and what is actually on the floor becomes a direct adjustment to the purchase price, and it is far easier to negotiate that adjustment before closing than to dispute it afterward.

Review any union agreement in detail

If the workforce is unionized, request the current collective agreement and understand its terms, because it generally continues to bind the business under a new owner who carries on the same operation — this follows from general principles of Canadian labour law, which sits with the provinces except for federally regulated sectors, so the specific rules depend on where and what the business does. This review belongs early in diligence, since it affects both the operating plan and the price a buyer is willing to pay. Ask specifically about grievances currently in progress, since an unresolved grievance does not disappear with a change of ownership.

Customer contracts and concentration

Manufacturing revenue is often concentrated among a handful of large accounts, and diligence should confirm both how concentrated it actually is and whether the underlying contracts are assignable to a new owner. A buyer who discovers late that a major supply agreement requires customer consent to assign has discovered a real risk to the deal timeline, not just a paperwork step. Where a single account represents a large share of revenue, ask directly whether that customer has any contractual right to be notified of, or to consent to, a change in ownership of its supplier.

Confirm the WSIB standing before you close

Under Ontario’s workplace safety and insurance framework, unpaid premiums tied to a business can follow the operation into new hands, which is why a current clearance certificate is a standard request before a manufacturing purchase closes — it confirms the seller’s account is in good standing and protects the buyer from inheriting a debt they had nothing to do with creating. Businesses operating in other provinces need the equivalent check under that province’s own workplace safety and insurance regime, since the specific administering body differs across the country.
