Understanding net working capital targets in M&A transactions

By Jordan Dixon, Corporate Finance Manager, Armstrong Watson

When preparing for a business sale, many owners understandably focus first on the headline valuation. However, as discussions progress, the mechanisms that sit beneath that headline figure become equally important. One of the most significant is the net working capital (NWC) target, a pricing adjustment tool designed to ensure fairness between buyer and seller.

NWC targets play a central role in most M&A transactions, yet they are often unfamiliar to those approaching the process for the first time. Taking the time to understand how working capital functions and how NWC targets are established can help prevent unexpected value movements and contribute to a smoother, more confident transaction process.

What is working capital and why does it matter?

Working capital represents the short‑term operating resources required for a business to trade normally. It reflects the funds tied up in the everyday cycle of buying, producing and selling goods or services.

Typically, working capital includes amounts owed by customers, stock or inventory, amounts owed to suppliers and prepayments and accruals associated with operational activity.

The exact components can vary depending on the business, but the principle remains the same. Working capital is the liquidity required to keep day‑to‑day operations running.

Because these balances naturally fluctuate, working capital needs to be assessed and normalised to ensure a fair position is delivered at completion.

What is a net working capital target?

A net working capital target is the benchmark against which the actual level of working capital at completion is measured. It ensures that neither buyer nor seller is advantaged or disadvantaged by timing differences within the normal trading cycle.

By establishing a target, both parties agree what constitutes an appropriate level of working capital for the business to operate as intended after the transaction completes. Any difference between the target and the actual working capital delivered at completion results in an adjustment to the purchase price on a pound‑for‑pound basis.

How is a NWC target calculated?

The target is usually calculated by analysing working capital over the most recent twelve‑month period. This timeframe typically captures seasonal variations and provides a reasonable view of what the business requires under normal conditions.

When determining the target, adjustments may be required to reflect non‑recurring or exceptional transactions, structural changes to the business, shifts in trading patterns, or periods of rapid growth that make earlier data less representative.

The aim is to establish a normalised level of working capital that accurately reflects the ongoing requirements of the business.

Why NWC targets matter

The impact of a NWC target can be significant.

For example, if a NWC target of £1 million is agreed and the business delivers working capital of £750,000 at completion, the purchase price would reduce by £250,000.

Conversely, if the business delivers £1.3 million of working capital, the purchase price would increase by £300,000.

This mechanism ensures that the economic position is balanced and that neither party benefits, or loses out, as a result of naturally fluctuating working capital levels.

Net Working Capital targets are a critical component of how value is ultimately delivered in an M&A transaction. Understanding both working capital itself and how NWC targets are derived can make a significant difference to transaction outcomes. With the right analysis and early engagement, business owners can approach negotiations with clarity and ensure that the agreed value is preserved throughout the process.
