Working capital is one of the most technically complex and frequently misunderstood elements of M&A transactions. It is also one of the most common sources of post-closing disputes between buyers and sellers. Despite its importance, many business owners enter the sale process without a clear understanding of how working capital targets are established, how the closing adjustment works, or how their day-to-day business decisions in the months before closing can impact their net proceeds.
This guide demystifies working capital in M&A, explaining the mechanics, the negotiation dynamics, and the practical strategies sellers can use to protect their interests.
In the context of an M&A transaction, working capital refers to the current assets minus the current liabilities that the business needs to operate on a day-to-day basis. The most common components are split as follows:
Cash, debt, and certain other items are typically excluded from the working capital calculation because they are handled separately in the purchase agreement (cash is retained or added to the price; debt is paid off at closing).
When a buyer acquires your business, they expect to receive a business that can operate normally from day one. That means the business needs an adequate level of working capital, enough receivables coming in, enough inventory on hand, and manageable payables, to sustain operations without requiring the buyer to inject additional capital immediately after closing.
The working capital adjustment ensures that the seller delivers a "normally functioning" business, not one that has been stripped of receivables or loaded with payables to inflate the seller's cash at closing.
Sellers sometimes inadvertently reduce working capital before closing by aggressively collecting receivables, delaying vendor payments, or drawing down inventory. While this may increase short-term cash, it typically triggers a dollar-for-dollar adjustment at closing, meaning the seller does not actually benefit.
Buyers want assurance that they are acquiring a business with enough working capital to operate without additional investment. They also want protection against sellers who might "harvest" working capital before closing.
The working capital target (sometimes called the "peg") represents the agreed-upon level of net working capital that should be in the business at closing. It is typically calculated as the average of trailing monthly working capital over a defined period, usually 12 months, though the specific period is negotiable.
Key negotiation point. The lookback period and calculation methodology can significantly impact the target. A 12-month average smooths seasonality but may include months that are not representative. A 6-month average may better reflect current operations but could be influenced by recent anomalies. Your advisor should help you evaluate which approach produces the most favorable and defensible target.
The closing adjustment is a four-step process that runs from the purchase agreement signing through the post-closing true-up.
Many purchase agreements include a "collar" or "de minimis" threshold, meaning small deviations from the target (typically within a defined range) do not trigger an adjustment. This prevents disputes over immaterial amounts.
Even a well-negotiated working capital mechanism can produce disputes. Six patterns account for most of them.
Working capital dynamics vary significantly across industries. Understanding the specific patterns for your sector helps you anticipate how the target will be calculated and where disputes are most likely.
Manufacturing businesses typically have significant working capital requirements due to raw material inventory, work-in-progress, and finished goods. Long production cycles and 60 to 90 day receivable terms can create substantial working capital needs. Seasonal production patterns in Wisconsin add additional complexity.
Service businesses usually have lower working capital requirements but may have significant accrued expenses such as unbilled revenue, deferred revenue, and prepaid contracts. The treatment of deferred revenue is a common negotiation point.
Inventory-heavy businesses require careful attention to inventory valuation methodology, obsolescence reserves, and seasonal inventory build-ups. The timing of closing relative to seasonal peaks can significantly impact the working capital calculation.
Construction businesses present unique working capital challenges due to project-based billing, retainage, work-in-progress accounting, and long receivable cycles. Job-level working capital analysis is often necessary.
Protecting your position on working capital requires proactive preparation and disciplined behavior in the months before closing. Seven strategies matter most.
Working capital adjustments can result in significant post-closing payments in either direction. Protecting your interests requires specific contractual provisions.
Working capital is technical, but it does not have to be confusing. The specific mechanics of how a target is set, how the closing adjustment works, and how disputes are resolved can meaningfully affect your net proceeds, which is why early planning pays for itself.
