Deal Breakage
Deal Breakage is a deal process term referring to a stage or document in the M&A transaction timeline.
Full Definition
Deal breakage refers to the failure of an M&A transaction after signing — when a deal that has been formally agreed upon (through an LOI or definitive agreement) fails to close. Deal breakage is distinct from deals that never reach the LOI stage; it specifically refers to the costly failure of transactions that appeared ready to close but fell apart due to financing failures, due diligence discoveries, regulatory blocks, MAC claims, or buyer/seller conduct issues. Deal breakage is more expensive, disruptive, and reputationally damaging than an early-stage deal that never developed.
The most common causes of deal breakage include: financing failure (buyer's lender withdraws commitment due to changed market conditions, underwriting issues, or failure to satisfy loan conditions); due diligence discoveries (material issues discovered during diligence that cause the buyer to exercise a contractual termination right or invoke a MAC clause); regulatory block (government agencies blocking the transaction on antitrust, national security, or sector-specific grounds); failure to satisfy closing conditions (third-party consents not obtained, required approvals not granted, or representations becoming untrue); and market disruption (significant adverse change in business conditions that triggers a Material Adverse Change provision).
The economic costs of deal breakage are substantial for both parties. Sellers incur transaction costs (legal, accounting, advisory fees) that are not recovered, suffer business disruption from the management distraction of the sale process, and face reputational implications of a "damaged goods" perception in any subsequent process. Buyers lose due diligence investment (often $50-200K in professional fees) and management time, and may face competitive disadvantage if the failed deal was with a strategic target.
Deal protection mechanisms are specifically designed to reduce breakage risk and allocate its costs. Breakup fees (paid by sellers who walk away from superior offers), reverse breakup fees (paid by buyers who fail to close), hell-or-high-water provisions (requiring buyers to accept regulatory conditions), and specific performance remedies (allowing the non-breaching party to compel closing) all reduce breakage risk by making deal failure costly for the breaching party.
For SMB deals, financing-related breakage is the most common form. SBA and conventional lender commitments are conditional — a final "clear to close" from the lender is not guaranteed even with a commitment letter in hand. Changes in interest rates, credit policy, or property appraisals can disrupt financing commitments between the commitment letter date and closing.
Seller vs. Buyer Perspective
Deal breakage is one of the most damaging events a seller can experience — both economically and psychologically. It exhausts you financially (transaction costs), depletes management focus, and can signal to the market that something is wrong with the business (even if the failure was entirely the buyer's fault). The best protection is selecting the right buyer in the first place: credible, financially qualified, experienced, and aligned on deal structure before exclusivity.
Negotiate deal protection provisions from the start: a meaningful reverse breakup fee (covering at least your transaction costs plus a premium), a financing commitment deadline that creates urgency, and a specific performance remedy if financing isn't the issue. These provisions don't prevent breakage but they create financial accountability that reduces the buyer's incentive to walk.
If a deal does break, move quickly to re-engage the market. The longer you wait post-breakage, the more "damaged goods" perception sets in. Brief your investment banker, update your materials, and consider whether to disclose the prior broken deal or simply restart with a fresh narrative.
Deal breakage is also costly for buyers — professional fees, management time, and reputational implications with advisors who don't want to bring you deals if you break them. The most effective breakage prevention is thorough pre-signing diligence: identify and resolve issues before signing the purchase agreement rather than discovering them after.
Be disciplined about your MAC and termination right standards. Using MAC provisions to exit deals that have experienced ordinary business fluctuations (not truly material adverse changes) is legally risky and reputationally damaging. Courts have set a high bar for invoking MAC — significant, durationally significant impairment of long-term earnings power is required, not short-term cyclical decline.
If you must break a deal, do it as early as possible once you've identified the unresolvable issue, and be transparent about the reason. Prolonging a deal you're not going to close — letting the seller continue incurring costs and forgoing other opportunities — is ethically questionable and may result in larger damage claims when you ultimately terminate.
Real-World Example
A buyer signs a $6.5M LOI for a specialty distribution company and enters exclusivity. During a 60-day diligence period, the buyer's SBA lender approves the loan but then discovers a UCC lien from an old factoring arrangement that the seller had not disclosed. The lien cleanup takes 3 additional weeks. With the exclusivity period expired and management distraction causing a 15% revenue decline in the quarter, the buyer invokes the absence of MAE as a termination right (disputed by the seller). The deal breaks after $220K in combined transaction costs. The seller re-engages the market 4 months later with a disclosure that a prior deal fell through — and receives offers 8% below the broken deal price, attributing the discount to buyer uncertainty about the underlying issue.
Why It Matters & Common Pitfalls
- !Undisclosed issues creating MAC triggers. Sellers who fail to disclose material issues in diligence invite post-signing MAC claims. Thorough pre-sale disclosure is the best prevention.
- !Financing conditions that are actually re-underwriting opportunities. Conditional lender commitments allow lenders to re-examine their credit decision based on new information — including appraisals, financial updates, and third-party reports. Sellers should understand that a commitment letter is not a guarantee of close.
- !Dispute over MAC definition. Buyers and sellers often disagree about whether a specific adverse development constitutes a MAC. Negotiate the MAC definition precisely — carve out market-wide conditions, industry-wide downturns, and known risks that the buyer accepted when signing.
- !Reputation damage from unnecessary breakage. Buyers who break deals without genuine cause — using diligence findings as pretexts to exit deals they've simply changed their mind about — develop reputations that reduce deal flow. The M&A advisor community tracks deal behavior closely.
