Running M&A Due Diligence That Surfaces Real Risk

M&A due diligence is the investigation a buyer conducts to understand what they're acquiring before closing. It examines the target's financials, legal standing, contracts, liabilities, employees, and compliance. The purpose is to surface real risk so the buyer can price the deal, negotiate protections, or walk away. Diligence is the buyer's core protection in any acquisition. Done well, it finds problems while they can still be addressed. This is general information, not advice on a specific deal.

Financial diligence tests whether the target's reported numbers reflect reality. It examines revenue quality, profit margins, working capital, cash flow, and whether earnings are sustainable. It also looks for one-time items or accounting choices that flatter the results. Because the entire deal is priced off the financials, this is the foundation of diligence. Weak or rushed financial diligence can mean overpaying or missing a fundamental problem.

A legal due diligence checklist typically covers corporate records and ownership, material contracts, pending or threatened litigation, intellectual property, employment matters, and regulatory compliance. It also examines licenses, permits, real estate, and any guarantees or off-balance-sheet obligations. Working systematically through such a checklist ensures nothing important is overlooked. A scattershot review, by contrast, tends to miss exactly the items that cause trouble later. The checklist turns diligence into a thorough, repeatable process.

Contract assignment review checks whether the target's key contracts can actually transfer to the buyer. Many contracts require the other party's consent to assign, and some prohibit assignment entirely or are triggered by a change of control. If important customer, vendor, or lease contracts can't transfer, the deal can lose much of its expected value. Identifying these issues during diligence allows you to obtain consents or renegotiate. Overlooking them can mean buying a business whose key relationships don't come with it.

Liability discovery is the part of diligence focused on finding obligations that don't appear plainly on the balance sheet. These can include pending or potential lawsuits, guarantees, tax exposure, environmental issues, and other contingent liabilities. Such hidden liabilities are exactly what diligence exists to uncover before they become the buyer's responsibility. Finding them allows the buyer to negotiate indemnities, adjust the price, or walk away. Missing them is a common source of post-closing regret.

The length of M&A due diligence depends on the size and complexity of the target and the scope of the review. Smaller, simpler deals may take a few weeks, while larger or more complex ones can take months. The diligence period is usually defined in the letter of intent or purchase agreement. Rushing it to save time is risky, because that's when significant problems slip through. A realistic timeline scaled to the deal is part of doing diligence properly.
