Key takeaways
- A reverse termination fee (RTF) is the buyer's payment to the seller if the buyer walks from a signed purchase agreement.
- Material adverse change (MAC) clauses define the conditions under which a buyer can exit — negotiating MAC language is one of the seller's most important purchase agreement tasks.
- Specific performance rights allow the seller to seek a court order forcing the buyer to close — a powerful but rarely exercised remedy.
- In lower middle market transactions, RTFs typically range from 3–6% of deal value — $600K–$1.2M on a $20M deal.
- Most deals that fall apart post-signing do so in gray areas — not clean financing failures. Negotiated termination provisions define who has leverage in those gray areas.

Buyer's primary exit mechanism from a signed purchase agreement
A signed purchase agreement is not a guaranteed closing. Buyers can walk from signed deals — for legitimate reasons (financing failure, regulatory block, material business deterioration) or for opportunistic ones (market shift, second thoughts, better deal elsewhere). When a buyer walks, the seller's recovery depends almost entirely on what was negotiated in the termination provisions of the purchase agreement.
Most founders who have not sold a business before assume that a signed purchase agreement means the deal is done. It does not. The purchase agreement contains detailed provisions governing when either party can terminate the deal, what happens when they do, and what remedies are available. These provisions are highly negotiated and their content varies significantly. Understanding what you have — and what you do not — before signing is one of the most important tasks in the M&A process.
Reverse termination fees: what they are and how they work
A reverse termination fee (RTF), sometimes called a buyer termination fee, is a fixed payment from the buyer to the seller if the buyer terminates the purchase agreement under specified circumstances. It is the seller's primary financial protection against a buyer who walks.
RTFs are most commonly applicable when: the buyer's financing fails (the buyer cannot close because their lender will not fund), a required regulatory approval is not obtained within the agreed timeline, or the buyer's representations are materially incorrect such that the buyer cannot close. In each case, the RTF is typically the seller's exclusive remedy — meaning the seller cannot sue for additional damages beyond the RTF amount.
The exclusivity of the RTF is critical. If the RTF is the exclusive remedy, the seller receives the RTF and nothing else — no ability to claim lost profits, deal costs, or other damages from the buyer's walk. Negotiate for a specific performance right alongside the RTF.
Dollar math: On a $20M deal with a 5% RTF, the seller receives $1M if the buyer walks due to a financing failure. The seller also incurred approximately $200K–$400K in transaction costs (legal, advisory, accounting). The RTF partially offsets those costs but does not compensate the seller for the time spent, the process disruption, or the cost of re-running the process. A higher RTF (7%) would produce $1.4M — still not full compensation, but better protection.
Material adverse change clauses
The material adverse change (MAC) clause — also called a material adverse effect (MAE) clause — defines the conditions under which a buyer can exit the purchase agreement without paying the RTF. A buyer who walks citing a MAC is not required to pay the RTF in most purchase agreements.
MAC clauses are among the most heavily negotiated provisions in any purchase agreement. The buyer wants a broad MAC definition — any significant negative development in the business permits exit. The seller wants a narrow MAC definition — only extraordinary, sustained changes to the business as a whole justify exit.
MAC definitions typically include both positive triggers (what constitutes a MAC) and carve-outs (what is explicitly excluded from the MAC definition). Standard carve-outs that sellers should fight for: general economic conditions, industry-wide conditions, changes in financial markets, changes in law or regulation that apply generally, and the announcement of the transaction itself.
The legal standard for a MAC is deliberately high — courts have historically held that a buyer asserting MAC must demonstrate a sustained, significant decline in the business, not a short-term or temporary change. But the litigation risk and uncertainty of disputing a MAC claim is expensive, so the negotiated definition still matters.

Schedule a conversation →Specific performance rights
Specific performance is a legal remedy that allows one party to seek a court order compelling the other party to perform their contractual obligations — in an M&A context, forcing the buyer to close the transaction. If a seller has specific performance rights and a buyer refuses to close without a valid basis, the seller can seek an order requiring the buyer to fund and complete the acquisition.
Specific performance is the most powerful seller remedy — more powerful than an RTF, which compensates the seller but does not actually close the deal. However, specific performance is also rarely used in practice, because litigation is expensive, time-consuming, and uncertain, and because most sellers would rather take the RTF and re-run the process than spend 12–18 months in court trying to force an unwilling buyer to close.
The value of specific performance rights is mostly deterrence. A buyer who knows the seller has the contractual right to force a closing — and the financial and legal wherewithal to pursue it — is less likely to walk opportunistically.
In lower middle market PE transactions, specific performance rights are typically available only against the PE fund itself (who has committed equity capital) and not against the fund's lender. The interplay between specific performance, the RTF, and the financing contingency requires experienced deal counsel.
Financing contingencies and the PE buyer walk
PE buyers finance acquisitions with a combination of equity (from their fund) and debt (from a bank or credit fund). The debt financing is not committed at LOI — it is committed at signing or in some cases finalized at closing. The financing contingency defines what happens when the debt financing fails.
Seller-favorable purchase agreements eliminate the financing contingency entirely (the buyer cannot exit due to financing failure — only the RTF applies). Buyer-favorable agreements allow the buyer to exit if financing fails, sometimes without paying the RTF if the financing failure is not the buyer's fault. Market standard in lower middle market transactions: RTF is payable if financing fails, and it is the seller's exclusive remedy for financing failure.
The practical risk: most PE buyer walks in lower middle market transactions do not involve a clean financing failure where a committed lender simply refuses to fund. Instead, they involve a buyer who uses the MAC clause, diligence findings, or a condition failure as the basis for exit — blurring the lines between a legitimate exit and an opportunistic one. This is why MAC clause negotiation, diligence scope agreements, and closing condition definitions matter as much as the RTF amount.

What is market in lower middle market transactions
The ABA Private Target M&A Deal Points Study and GF Data provide benchmarks on termination provisions in lower middle market transactions. Key data points for deals in the $10M–$75M range:
The prevalence of RTFs varies by buyer type. PE buyers (who use debt financing) almost always have RTF provisions because financing failure is a real risk. Strategic buyers (who typically do not use deal-specific financing) may not have RTFs because their ability to close is not dependent on a lender's decision.
The outside date — the date by which the deal must close or either party can terminate — is an important but often overlooked provision. If regulatory approval takes longer than expected or diligence extends, the outside date may trigger a termination right before the deal can close. Negotiate a reasonable outside date with extension provisions for regulatory delays.

Frequently asked questions
Can a seller walk from a signed purchase agreement?
Yes. The purchase agreement defines seller termination rights as well as buyer termination rights. Common seller termination triggers: buyer fails to perform a material covenant, buyer's representations are materially incorrect, or the outside date passes without closing. If the seller terminates for a buyer breach, the seller typically seeks the RTF (if applicable) and potentially additional damages.
What happens to a deposit when a buyer walks?
If the purchase agreement includes an earnest money deposit, the deposit is typically forfeited to the seller when the buyer walks without a valid contractual basis. The deposit functions as a pre-agreed liquidated damages amount — similar in concept to an RTF.
How do I negotiate a higher RTF?
RTF negotiation depends on leverage, buyer type, and deal dynamics. Arguments for a higher RTF: your business is large enough that a failed process is very costly to restart; you have competing offers that you are giving up to enter exclusivity; the buyer's financing is from an unusual or less certain source.
Does the MAC carve-out for "announcement effects" protect against customer churn after announcement?
It protects against the buyer asserting that announcement-related customer uncertainty constitutes a MAC that allows exit. It does not prevent actual customer churn from being a MAC if it is material and sustained. The distinction is between a normal post-announcement disruption (excluded) and a material deterioration that persists (potentially a MAC).
What should I do if a buyer tries to exit citing MAC after a minor business disruption?
Engage your deal counsel immediately. The legal standard for MAC is high — courts rarely permit exits for short-term disruptions. Your position should be: (1) the disruption does not meet the MAC standard; (2) the buyer is in breach by attempting to exit; and (3) you are prepared to seek specific performance. Even if you ultimately accept the RTF, asserting these positions preserves leverage in any negotiation.
