Net Debt: Definition and Calculation in M&A

Net debt is one of the most fundamental concepts in M&A and Transaction Services. It bridges enterprise value (EV) — the total value of a business — to equity value — the amount that shareholders actually receive. Understanding how to calculate it, and more importantly how to argue about it in a deal context, is essential for any TS analyst.

The Basic Definition

Net debt is typically defined as:

Net Debt = Financial Debt − Cash and Cash Equivalents

In its simplest form, if a company has €10m of bank loans and €3m of cash on its balance sheet at the transaction date, net debt is €7m. Equity value = EV − Net Debt, so in a deal at a €50m EV, equity holders receive €43m.

Why "Simple" Net Debt Is Never Enough

In practice, the net debt calculation in M&A goes far beyond the basic formula. Both buyers and sellers have strong incentives to expand or contract the definition, since every item included reduces equity value and every item excluded increases it.

Items Typically Included in Net Debt

• Bank loans, revolving credit facilities, term loans
• Finance lease obligations (particularly post-IFRS 16)
• Shareholder loans and intra-group debt
• Overdrafts and factoring liabilities
• Deferred revenue (in some deal contexts, treated as debt-like)
• Pension deficits (on a buy-side basis)

Debt-Like Items (Sometimes Contested)

• Earnout liabilities from prior acquisitions
• Environmental remediation liabilities
• Deferred tax liabilities with near-term crystallisation
• Restructuring provisions not yet utilised
• Contingent liabilities under litigation

Items Typically Excluded (Cash-Like)

• Restricted cash pledged as collateral
• Excess cash above a normalised level
• Short-term financial investments

Net Debt at Completion vs. Locked-Box

The treatment of net debt differs depending on the deal mechanism:

• Completion accounts: Net debt is calculated at the actual closing date, based on a completion balance sheet prepared post-closing. There is a true-up mechanism if the actual figure differs from the estimate at signing.
• Locked-box: Net debt is fixed at a reference date (the locked-box date). The buyer benefits from any cash generated between that date and closing, subject to leakage provisions.

Common Interview Questions on Net Debt

Interviewers at Big 4 and boutique TS teams frequently ask:

• "Walk me through how you would calculate net debt in a deal."
• "Is deferred revenue net debt? Under what circumstances?"
• "How does IFRS 16 affect net debt?"
• "What is the difference between financial debt and debt-like items?"

For each question, the answer must be structured and commercially grounded — not just a recitation of definitions.

Conclusion

Net debt is simple in theory and complex in practice. In every Transaction Services engagement, the net debt schedule is a battleground between advisers, and the ability to argue specific items with rigour is a core TS skill.
