Net Working Capital in M&A: What Sellers Need to Know
Net working capital (NWC) is one of the most misunderstood parts of a business sale. Many owners hear terms like working capital target, peg, or post-close adjustment and immediately worry that the buyer is trying to chip away at price. In most well-run transactions, that is not the goal.
NWC adjustments are typically used to keep the deal fair for both sides by making sure the company is delivered with a normal level of short-term operating liquidity at closing.
What Is Net Working Capital?
At a high level, net working capital is current operating assets minus current operating liabilities. In many deals, this often includes items like:
- Accounts receivable
- Inventory
- Prepaid expenses
- Accounts payable
- Accrued operating expenses
Exact definitions vary by deal and should be clearly spelled out in the purchase agreement.
Why NWC Matters in a Sale
The purchase price usually reflects the value of the business as an ongoing operation, not a business that has been stripped of short-term operating resources. If working capital is materially lower than normal at closing, the buyer may have to inject immediate cash just to run day-to-day operations. If it is materially higher, the buyer may be receiving extra value beyond what was assumed in pricing.
An NWC target helps avoid either side being unfairly advantaged by timing decisions right before close.
The Working Capital “Target” (or “Peg”)
Most transactions set a target based on historical normalized levels of working capital. Common approaches include trailing averages (often adjusted for seasonality) and quality-of-earnings style normalization analysis.
At closing, actual NWC is compared to the agreed target:
- If actual NWC is below target: purchase price is typically adjusted downward.
- If actual NWC is above target: purchase price is typically adjusted upward.
When structured correctly, this is a balancing mechanism, not a one-way penalty.
Why Sellers Often Feel Surprised
Sellers are often surprised by NWC adjustments for three reasons:
- Unclear definitions: Different views on what should or should not be included.
- Seasonality: Closing in a high or low cycle month can distort the picture.
- One-time events: Unusual receivables, inventory purchases, or payables timing can skew calculations.
These are solvable issues when addressed early with clear data and definitions.
How NWC Supports Fairness for Both Parties
- For buyers: protects against inheriting a business underfunded for normal operations.
- For sellers: protects against overfunding the company without being compensated for it.
Done right, the adjustment aligns economics with reality at close and reduces post-closing disputes.
How Sellers Can Prepare Early
- Start early: Review 12–24 months of monthly working capital trends.
- Normalize: Identify one-time or non-operating items before buyer diligence starts.
- Define clearly: Get precise line-item definitions in the LOI and purchase agreement.
- Model scenarios: Understand potential adjustment outcomes before signing final docs.
- Coordinate advisors: Ensure broker, CPA, and legal teams use the same framework.
Common Mistake to Avoid
One of the biggest mistakes is treating working capital as a final-week legal issue instead of a financial planning issue. By the time closing documents are finalized, leverage is lower and options are narrower. Early diligence preparation creates better outcomes.
Final Takeaway
Net working capital adjustments are typically not about manipulating price. They are usually about delivering a business at a fair, normalized operating level at closing. Sellers who understand this early can negotiate from a position of clarity and reduce surprises during final deal execution.
