Earn-outs, Seller Notes and Rollovers — Read Before You Sign

In the high-stakes world of mid-market M&A, the "headline price" is often a siren song. It is the number that makes the headlines and satisfies the ego, but for the sophisticated business owner, it is merely the starting point. The true value of a transaction is not found in the gross figure written in the Letter of Intent (LOI), but in the granular details of the deal structure.

In today’s economic climate—characterised by higher interest rates, rigorous bank credit committees, and valuation gaps between optimistic sellers and cautious buyers—"Cash at Closing" is increasingly becoming a rarity for the full purchase price. Instead, deals are being held together by a trinity of deferred payment mechanisms: Earn-outs, Seller Notes, and Equity Rollovers.

Understanding these tools is not just for the lawyers; it is a strategic necessity for any owner looking to secure their financial legacy.

The Earn-out: Bridging the Valuation Gap

An earn-out is a contractual provision where a portion of the purchase price is paid after the closing, contingent on the business achieving predefined financial or operational milestones. Typically, these milestones are tied to EBITDA or Revenue targets over a one-to-three-year period.

Earn-outs are the ultimate "bridge." If a seller believes the business is about to explode in growth due to a new product launch, but the buyer views that growth as unproven, an earn-out allows the buyer to say: "If you hit those numbers, we will pay you for them. If you don't, we won't."

However, for the seller, an earn-out is a risk-shifting mechanism. You are essentially providing "vendor financing" for the buyer’s acquisition. The primary danger is the loss of control. Once the deal closes, the buyer owns the company. They may make decisions—such as increasing central overheads, changing the sales strategy, or investing in long-term R&D—that depress short-term EBITDA and, consequently, your earn-out.

Advisor’s Tip: When negotiating an earn-out, focus on "negative covenants." These are contractual restrictions that prevent the buyer from making extraordinary changes to the business that would unfairly penalise the earn-out calculation. Better yet, try to tie the earn-out to top-line Revenue rather than bottom-line Profit to minimise accounting manipulation.

The Seller Note: Acting as the Bank

A Seller Note (or Vendor Loan) is effectively a loan from the seller to the buyer. Instead of receiving £10 million in cash, you might receive £8 million in cash and a £2 million promissory note from the buyer, to be repaid with interest over several years.

In the current market, Seller Notes are often a requirement from the buyer's senior lenders. Banks like to see "skin in the game" from the seller; it confirms your confidence in the business’s future stability. Furthermore, it helps the buyer bridge the "funding gap" when bank debt is insufficient.

The risk here is pure credit risk. If the business fails under the new ownership, the seller note may never be repaid. In most cases, these notes are "subordinated" to bank debt, meaning the bank gets paid first, and the seller only gets paid if there is enough cash left over.

Advisor’s Tip: Ensure the interest rate on the Seller Note reflects the risk. You are taking on the risk of a junior lender, so the coupon should be significantly higher than what a bank would charge. Additionally, look for "acceleration clauses" that make the full amount due immediately if the buyer sells the company again.

The Equity Rollover: The Second Bite of the Apple

Common in Private Equity deals, an equity rollover involves the seller reinvesting a portion of their sale proceeds into the buyer’s new holding company. Typically, this ranges from 10% to 25% of the total value.

The appeal of the rollover is the "Second Bite of the Apple." If you sell to a private equity firm that doubles the size of the business through bolt-on acquisitions and operational improvements, your remaining 20% stake could eventually be worth as much as the 80% you originally sold. It allows you to diversify your wealth while retaining an interest in the upside.

The downside is that you are now a minority shareholder. You no longer call the shots. You are "locked in" until the majority owner decides to sell, which could be five to seven years down the line. You also face "dilution" risk if the company requires more capital later on.

Advisor’s Tip: Pay close attention to the Shareholders' Agreement (SHA). You need robust "Tag-Along" rights (if they sell, you can sell on the same terms) and "Pre-emption" rights (the right to maintain your percentage if new shares are issued).

Tax and Integration: The Hidden Variables

Structure is not just about risk; it is also about what you keep after the taxman takes his share. In the UK, for instance, the treatment of an earn-out depends heavily on whether it is classified as part of the capital gain or as employment income (if the seller stays on as an employee). The latter is taxed at significantly higher rates.

Similarly, a rollover must be structured carefully to ensure "Tax Neutrality." You do not want to be in a position where you owe capital gains tax on the 100% value of the deal when you have only received 75% in cash.

Beyond tax, these structures dictate the "vibe" of the post-acquisition period. A large earn-out means the seller is effectively an employee with a massive bonus on the line, which can lead to friction with the new owners. A large rollover makes the seller a partner. A clean cash deal allows for a clean break.

Conclusion: Balancing the Scales

There is no "perfect" deal structure, only the structure that best manages the specific risks of your business and your personal goals.

• If you want a clean break and zero future risk: Push for maximum Cash at Closing, even if it means a slightly lower headline price.
• If you are bullish about the future and trust the buyer: A Rollover or Earn-out can provide a significant "kicker" to your total wealth.
• If the market is tight: A Seller Note might be the only way to get the deal across the finish line.

Before you sign an LOI, look past the big number. Ask your advisors to model the "Net Present Value" and the "Risk-Adjusted Value" of the structure. Only then will you know what your company is truly being sold for.
