What Happens When a Deal Falls Through

Let me tell you something that will sound alarming if you're planning to sell your business: somewhere between 30% and 50% of signed letters of intent never make it to closing. That's not a typo. Even after a buyer has committed in writing to purchase your business at an agreed price, there's a coin-flip chance the deal dies somewhere between LOI and the closing table.

I've watched deals collapse for every reason imaginable — and a few I never could have predicted. Understanding why deals fail, and what to do when yours does, is some of the most valuable knowledge a business seller can have.

The Most Common Deal Killers

Quality of earnings findings. This is the single biggest deal killer I see. The buyer hires an accounting firm to perform a quality of earnings analysis, and the adjusted EBITDA comes back lower than what the seller represented. Maybe the seller was adding back expenses that aren't truly add-backs. Maybe revenue recognition was aggressive. Maybe there were one-time revenues booked as recurring. Whatever the cause, when the QoE reduces EBITDA by 15-20%, the deal either reprices or dies. I've seen a $30M deal collapse because the QoE reduced EBITDA from $5M to $3.8M — the buyer walked rather than pay a 7x multiple on inflated numbers.

Customer concentration discovered in diligence.The seller mentioned their "diversified customer base" in marketing materials, but diligence reveals that three customers represent 60% of revenue, and one of them is on a month-to-month contract. Buyers don't want to pay 6x EBITDA when a single phone call from a customer could wipe out half the earnings. This kill shot is especially common in manufacturing, staffing, and B2B services.

Legal landmines.Undisclosed litigation, environmental liabilities, regulatory compliance gaps, or IP ownership disputes that surface during legal due diligence. I worked on a transaction where the target company had been using a competitor's patented manufacturing process for years without a license. The potential liability was unquantifiable, and the buyer walked immediately.

Financing falls through.The buyer's lender pulls out, the SBA loan doesn't get approved, or the buyer's equity commitment falls short. This is more common in deals under $10M where buyers are relying on SBA 7(a) loans or seller financing. A change in interest rates, a weak appraisal, or a hiccup in the buyer's personal financial situation can torpedo the deal. In the 2023-2024 rate environment, I saw financing kill more deals than any other single factor.

The retrade.This is the one that makes sellers' blood boil. The buyer signs an LOI at one price, conducts diligence, and then comes back with a lower offer — sometimes 15-25% lower — citing "findings" that may or may not be legitimate. Some buyers retrade as a strategy, knowing the seller has invested months and emotional energy into the deal. Others retrade because they genuinely found issues. Either way, it's the most contentious moment in any deal process.

Seller cold feet.It happens more often than people think. The seller gets to the closing table, looks at the paperwork, and realizes they're about to hand over the business they built for 25 years. The emotional weight is overwhelming, and they pull out. Sometimes it's framed as "the terms aren't right" or "the timing is off," but the real reason is grief and fear.

External events. Market downturns, industry disruption, regulatory changes, or black swan events. COVID killed hundreds of deals in March 2020. The 2022-2023 rate hikes killed hundreds more. You can do everything right and still lose a deal to forces beyond your control.

What to Do When Your Deal Falls Apart

The call comes in. The buyer is out. Whether they walked, you walked, or financing collapsed, you're back to square one with a business that's been "on the market" for months. Here's how to handle it.

First, contain the damage.If employees found out about the deal, they're now worried and uncertain. Address it head-on — tell them the deal didn't go through, the business is continuing as normal, and their jobs are secure. If customers knew, reassure them too. The worst thing you can do is let rumors fill the vacuum.

Second, understand why it failed. Get a clear, honest postmortem from your advisor. Was it a buyer issue (financing, cold feet, retrade) or a business issue (QoE adjustments, legal problems, customer concentration)? This distinction matters enormously because it determines what you need to fix before trying again.

Third, address the fixable issues. If the QoE showed EBITDA adjustments, work with your accountant to clean up your books and present financials more accurately. If customer concentration was the issue, spend 12-18 months diversifying. If it was a legal problem, resolve it. The time between a failed deal and a new attempt is your window to strengthen the business.

Fourth, manage the "shopped" stigma.When you go back to market, sophisticated buyers will ask why the previous deal fell through. Some will assume the worst — that diligence uncovered something terrible. You need a credible, honest explanation ready. "The buyer's financing fell through" is very different from "the buyer found accounting irregularities." Be truthful but strategic in how you frame it.

The Re-Marketing Challenge

Going back to market after a failed deal is harder than going to market the first time. There's a real stigma in the M&A community around "busted deals." Buyers and their advisors will wonder what the previous buyer found, and they'll dig harder during diligence as a result.

The timing matters. If you re-market immediately, it signals desperation. If you wait too long, your financials age and the business may drift. In most cases, I recommend waiting 6-12 months — enough time to address whatever killed the first deal and generate fresh financial data that shows the business is healthy and growing.

Confidentiality becomes even more critical the second time around. If word got out during the first process, you've already taken a hit. Competitors may have used the information against you with customers. Employees may have started looking elsewhere. A tighter, more controlled process the second time is essential.

Consider changing advisors if the first process was poorly managed. A fresh broker or investment banker brings a new buyer network, fresh positioning, and no baggage from the failed deal.

Prevention: Stronger Preparation, Better Outcomes

The best way to handle a failed deal is to prevent it in the first place. Not every failure is preventable — you can't control financing markets or buyer psychology — but you can eliminate most of the common causes.

Get your own QoE done first. Hire an accounting firm to perform a sell-side quality of earnings before you go to market. Yes, it costs $30K-$75K. But it accomplishes two things: you find out what your adjusted EBITDA actually is before you set an asking price, and you hand the report to buyers, giving them confidence in the numbers and reducing their diligence timeline.

Qualify your buyers harder. Before granting exclusivity, verify that the buyer has committed financing (or the capital on hand), has done deals before, and has realistic expectations about timeline and process. An LOI from an unqualified buyer is worse than no LOI — it wastes three to four months and exposes your business to risk.

Negotiate stronger LOI terms. The letter of intent should include a clear timeline for diligence (45-60 days, not open-ended), a deposit that the buyer forfeits if they walk for non-specified reasons ($50K-$250K depending on deal size), and a specific list of diligence items so both parties know the scope upfront.

Maintain a backup buyer.In a competitive process, keep your second-choice buyer warm during the exclusivity period. Don't violate your exclusivity agreement, but stay in communication. If the primary deal falls apart, you can pivot to the backup buyer within weeks rather than re-starting the entire process.

Prepare thoroughly before going to market. The most important prevention of all. A well-prepared seller with clean financials, diversified customers, resolved legal issues, and a strong management team will close 80%+ of signed LOIs. An unprepared seller is playing roulette.

When Walking Away Is the Right Call

Sometimes the deal falling through is actually the best outcome for the seller. If the buyer was retading aggressively, if the terms had shifted so far from the original LOI that the deal no longer made financial sense, or if diligence revealed that the buyer was undercapitalized or inexperienced — walking away protects you from a bad transaction.

I tell sellers: a bad deal closed is worse than no deal at all. If you sell to the wrong buyer at the wrong price with the wrong structure, you'll spend years regretting it — especially if there's an earn-out you'll never collect, or a seller note that goes into default. The failed deal stings today, but it might save you from a much worse outcome.

The Bottom Line

Deals fall apart. It's a statistical reality of M&A. The sellers who navigate it best are the ones who prepare thoroughly to minimize the risk, stay emotionally grounded when things go sideways, fix what needs fixing, and get back to market when the time is right. A failed deal is a setback, not an ending — unless you let it become one.
