Equity Bridge: The bridge between Enterprise Value and Equity Value

How purchase price adjustment mechanisms work in M&A transactions

Equity Bridge: How to correctly calculate Enterprise Value and Equity Value

Valuing a company is one of the central issues in every M&A transaction – and simultaneously one of the most frequently misunderstood. In many negotiations, buyers and sellers agree relatively quickly on a company value, for example in the form of an enterprise value. But this value is not what the seller actually receives in the end.

This is precisely where the actual mechanics of a transaction begin: the so-called equity bridge. It describes the path from the negotiated company valuation to the actual purchase price paid. Anyone who doesn't understand this mechanism risks unpleasant surprises at closing – and that's exactly why a closer look is worthwhile.

"Enterprise value is negotiated. Equity value is calculated."

Enterprise Value vs. Equity Value:

More than just a difference in calculations

Enterprise value is the starting point for almost every valuation. It describes the value of the operating business, regardless of how it is financed. It is typically calculated as a multiple of adjusted EBITDA and serves as a common basis for price negotiations.

Equity value, on the other hand, is the amount that actually flows to the shareholders. It is derived from the enterprise value, adjusted for net debt and – depending on the structure – for working capital deviations. This transforms an abstract valuation into a concrete figure.

In practice, this difference is crucial: While the Enterprise Value is often the focus of communication, the Equity Value determines the amount the seller actually realizes.

The Equity Bridge:

From company value to purchase price

The equity bridge is not a single calculation step, but rather an interplay of several components. It begins as early as the due diligence phase and is precisely defined in the purchase agreement. Often, the true impact of this mechanism only becomes apparent at closing.

First, an enterprise value is agreed upon, based on a specific valuation basis. However, this basis is rarely "raw" but is usually adjusted through so-called normalizations. The goal is to present a sustainable, representative result – free from one-off effects.

One-off costs such as severance payments or extraordinary repairs are regularly excluded from the valuation. This is where significant leverage lies, as every adjustment directly impacts the company's value. Small differences in EBITDA are multiplied by the valuation multiple and quickly lead to significant purchase price deviations.

LTM and valuation time:

Dynamics between signing and closing

In many transactions, the purchase price is calculated based on the so-called "last twelve months," meaning the twelve months prior to closing. This approach takes into account the fact that companies evolve between signing and closing.

A clear distinction is crucial: LTM logic pertains to operational performance and thus forms the basis of enterprise value. It should not be confused with balance sheet adjustments such as working capital or net debt. This distinction is key, but in practice, the two are frequently conflated – with corresponding consequences for purchase price calculation.

Working Capital:

Ensuring operational capability

Another key component of the equity bridge is working capital. It ensures that the company is handed over with an adequate level of operational liquidity. Buyers expect that the business can continue "normally" without having to immediately inject additional capital.

The purchase agreement defines a so-called target working capital. This describes the ideal state in which the company should be transferred. At closing, the actual working capital is then measured and compared with this target value.

If the actual working capital is higher than agreed, the purchase price increases. If it is lower, the payment is reduced accordingly. This mechanism is not an additional burden, but merely serves to establish the agreed economic situation.

Net Debt:

The direct influence on the purchase price

Besides working capital, net debt plays a key role. It is subtracted from the enterprise value to determine the equity value. The logic is simple: The buyer assumes the company's debt – and therefore pays the seller less.

Here, too, a target value is often defined. If the actual net debt deviates from this, an adjustment is made. More debt leads to a lower purchase price, less debt to a higher one.

This mechanism is often underestimated by entrepreneurs. They tend to focus on the negotiated company valuation, while the actual payout is significantly influenced by these adjustments.

Practical example:

Medium-sized machine manufacturer

A medium-sized company with annual sales of approximately €50 million generates an EBITDA of €7 million. Based on an agreed multiple of 5, this initially results in an enterprise value of €35 million.

However, adjustments are made as part of the due diligence process. Severance payments of €500,000 and extraordinary repairs of €500,000 are classified as non-recurring and added to EBITDA. The adjusted EBITDA is therefore €8 million, resulting in a new enterprise value of €40 million.

Further adjustments are made based on this. The actual net debt is €5 million, while the contract stipulates a target net debt of €4 million. This results in a purchase price reduction of €1 million.

Additionally, working capital is taken into account. With a target value of €3 million and an actual value of €2.8 million, this results in a shortfall of €200,000, which also leads to a reduction in the purchase price.

The final calculation is therefore as follows:

• Enterprise Value (normalized): €40,000,000

• Net Debt Adjustment: –€1,000,000

• Working capital adjustment: –€200,000

Equity Value: €38,800,000

This example clearly shows that the originally negotiated price has only limited significance. The decisive factor is the concrete implementation of the equity bridge.

Typical points of contention:

Where deals are renegotiated

In practice, many conflicts arise not during the assessment itself, but during its implementation. Discussions frequently focus on which normalizations are justified and how individual positions are defined.

The definition of working capital is also regularly the subject of intensive negotiations. Which items are included, how to handle advance payments, or whether certain liabilities are taken into account can have a significant impact on the purchase price.

Additional issues include intercompany transactions and accounting valuation problems. The more unclear the contractual provisions are, the greater the risk of disputes after closing.

Double dip and misunderstandings in practice

A frequently discussed topic is the so-called "double dip." This stems from the concern that certain values—especially working capital—are being counted twice.

In fact, this is not the case with a properly structured transaction. The enterprise value is based on the assumption of a normal working capital level. The subsequent adjustment merely serves to ensure that this level actually exists.

Therefore, this is not a double burden, but rather a precise alignment with the agreed-upon state of the company.

Profits carried forward:

Why they often play no role in the purchase price

A common misconception among sellers concerns the significance of retained earnings. Many business owners assume that profits accumulated over years directly increase the purchase price. After all, this money was generated within the company and not distributed. However, in the logic of M&A transactions, this conclusion is only convincing at first glance.

The reason lies in the methodology of business valuation. Enterprise value is not based on historical profit development, but on the company's future earning power. What matters is not what was earned in the past, but what can be earned in the future. Past profits are therefore only relevant insofar as they are reflected in a sustainable earnings base – typically EBITDA.

From an accounting perspective, retained earnings are part of equity. However, they do not constitute an independent value driver in the context of determining the purchase price. The decisive factor is rather whether these earnings still exist today in a form that is economically tangible for the buyer.

If profits are available as liquidity within the company, they increase its value – not because they are "profits" in the traditional sense, but because they reduce net debt as cash. This effect is thus reflected in the net debt mechanism. However, if the profits have already been reinvested, for example in equipment, personnel, or growth, then they are part of the operating business and therefore already included in the enterprise value.

For the purchase price logic, this means:

It is not the historical profit retention that is paid for, but solely the current economic condition of the company.

Or, to put it more pointedly:

"Buyers don't pay for what you earn. They pay for what remains."

This shift in perspective is crucial for sellers. Those who understand that past profits are only relevant if they are still reflected in the company today can better understand the mechanics of the equity bridge – and develop more realistic expectations regarding the final purchase price.

Cash/Debt-Free:

The standard of modern transactions

In most transactions, a so-called cash/debt-free structure is agreed upon. The buyer acquires the company as if it were debt-free. Debts are deducted from the purchase price, while any excess liquidity is attributed to the seller.

This structure ensures clarity and comparability, as the company value is considered independently of the financing structure.

Locked Box vs. Completion Accounts:

Two ways to determine the purchase price

Finally, it is important to distinguish when and how adjustments are made. With a locked box structure, the purchase price is defined based on a fixed cut-off date and remains unchanged thereafter. This creates planning certainty but shifts the risk between signing and closing to the buyer.

In contrast, completion accounts determine the final purchase price after closing based on actual figures. This is more precise, but often leads to subsequent disputes.

Conclusion:

Understanding the Equity Bridge means understanding the deal.

The equity bridge is not a technical detail, but the central mechanism for determining the actual purchase price. It decides how a negotiated company valuation becomes a concrete payment.

For entrepreneurs, this means: The focus should not only be on the enterprise value, but on the entire structure of the transaction. Only those who understand the interrelationships between EBITDA, net debt, and working capital can make informed decisions and effectively protect their negotiating position.

A well-structured equity bridge creates transparency, reduces the potential for disputes, and ultimately leads to what every transaction should achieve: a fair and comprehensible result for both sides.
