Why Deals Collapse After the LOI Is Signed

The LOI gets signed and suddenly everyone at the table - the broker, the M&A attorney, the accountant who has been billing you since the Clinton administration - starts talking about champagne. Which is premature. The letter of intent is not a deal. It's an agreement to do more work before deciding whether there is a deal. And a surprising number of owners learn that distinction the hard way, usually somewhere around month four of a six-month process, when the buyer's quality-of-earnings team finds something nobody was expecting.

Industry data puts the LOI-to-closing failure rate somewhere between 25% and 50%. One business broker with extensive deal experience put it plainly: once an LOI is negotiated and signed, there's still only around a 50/50 chance the deal will close. That number sits quietly in the background of every transaction, which is why good advisors spend as much time preparing sellers for due diligence as they do negotiating the headline price. The headline price is what gets celebrated. Due diligence is what determines whether you actually see it.

None of this means the LOI is meaningless - it anchors price, establishes exclusivity, and sets the timeline for what happens next. But it is not a closing. And the owners who get blindsided by a deal collapse are almost always the ones who treated the LOI like the finish line rather than the starting gun for the hardest part of the race. In my experience, the hardest part is not the negotiation. It's the diligence - and the preparation that should have happened well before it started. I want to walk through the reasons deals fall apart, because understanding them is half the battle. The other half is fixing them before you ever get to a letter of intent.

What Kills More Deals Than Anything Else: Financial Surprises in Due Diligence

The buyer's quality-of-earnings report - the QoE - is where most LOI-stage deals go to die.

It's a detailed forensic review of your financials, and its job is to validate that the earnings you presented in your confidential information memorandum actually reflect what the business produces on a normalized, sustainable basis. According to Axial's 2025 Dead Deal Report, which analyzed 75 unsuccessful middle-market transactions, QoE EBITDA discrepancies caused 21.3% of broken LOIs - making it the second-most-common deal killer, right behind broader non-QoE diligence findings at 25.3%. When the QoE finds something the seller didn't expect, things get difficult fast, as of August 2026.

The most common financial surprise is adjusted EBITDA that doesn't hold up under scrutiny. Every business sale starts with an EBITDA number, and sellers - sometimes with help from optimistic advisors - add back expenses they believe are legitimate: personal vehicle leases, family member salaries, one-time legal fees, owner perks that genuinely disappear post-sale. When a sophisticated buyer's team reconstructs the profit and loss statement, they'll challenge every one of those add-backs. The ones that don't hold up reduce the multiple and therefore the purchase price. The Axial report included a deal where an independent sponsor terminated a letter of intent after discovering the banker had overstated EBITDA by 25%. That's not a rounding error. That's a completely different business.

Revenue recognition issues are close behind. If your revenue recognition doesn't match GAAP - and for most closely held businesses, it doesn't - the QoE team will restate it. Deferred revenue, milestone billing, and long-term contract treatment can all move revenue between periods in ways that dramatically shrink the trailing twelve months. There's a real pattern in small business deals where a seller admits, in the first post-LOI meeting, to significant financial reporting that doesn't reflect the tax returns - one documented example involved a 50% discrepancy between reported and actual income that came out only after the LOI was signed. When that happens, the financing math changes, the multiples change, and trust evaporates at the moment you need it most.

Then there are the undisclosed liabilities. Payroll tax arrears. Pending or threatened litigation. Deferred maintenance on critical equipment. Lease obligations with personal guarantees. Buyers pay for what they think they're getting, and when the due diligence team finds things that weren't in the disclosure schedules, the trust breaks down. The Axial report documented one case where undisclosed criminal charges surfaced early in diligence and killed the deal entirely. Not because the business was fatally flawed - because the non-disclosure made the buyer question everything else.

Customer concentration straddles financial and operational risk but almost always surfaces in diligence. The Axial report cited a family office that walked from a deal because 40% of revenue came from government sponsorship in California - a single funding stream the buyer decided was too concentrated to accept. Most private equity buyers flag concern when any single customer exceeds 15-20% of revenue. Above 30%, expect either a lower multiple, a higher holdback, or a renegotiated deal structure. I've seen cases where a single customer relationship - perfectly legal, perfectly healthy - turned a clean exit into a renegotiated mess, purely because the concentration number crossed a threshold.

The pattern is almost always the same: an owner who genuinely believes their numbers are solid, because they are solid from their own perspective. But "solid" and "will survive a quality-of-earnings report" are different things. The fix is not complicated, but it requires doing it before you're in diligence. Work with your accountant or exit advisor to model what a QoE would find. Address undisclosed liabilities before someone else discloses them for you. The owners who do this find their deals close cleaner, faster, and at prices far closer to what was agreed in the LOI.

The Working Capital Trap and Why Buyers Use It

Most sellers focus on the headline purchase price and treat everything else as details to sort out later.

Working capital is not a detail. It is one of the most reliable mechanisms for reducing what actually hits a seller's bank account at closing, and most owners don't fully understand how it works until it costs them something.

Here's how it works in plain terms: when a business is sold, the buyer expects to receive a "normal" level of working capital - accounts receivable, inventory, and other current assets minus current liabilities - as part of the deal. The purchase price is struck based on a target working capital peg, which is supposed to represent the amount needed to run the business at its ordinary operating level. If working capital at closing is below the peg, the seller pays a dollar-for-dollar adjustment downward. If it's above, the seller collects more. Simple enough in theory. Considerably messier in practice.

Consider what one pre-LOI diligence checklist documented: a seller planning to pull $150,000 in accounts receivable and cash before close, while the buyer needed that working capital to fund payroll and materials in the first 60 days. The buyer effectively paid $1.35 million for what was priced as a $1.2 million business - and didn't find out until after the LOI was signed. That is a working capital dispute waiting to happen. The peg calculation needs to be right, and it needs to be in the LOI - not worked out "later" over a closing binder that's due in 48 hours.

Sellers make two common mistakes. First, they don't understand what goes into the peg calculation - which items count, which measurement dates apply, whether seasonality affects the baseline. Second, they run the business during the diligence period in ways that reduce working capital, sometimes without realizing it: delaying collections on receivables, drawing down inventory faster than usual, taking owner distributions that shift the ratio. Buyers' advisors notice all of this. Working capital adjustments routinely move purchase prices by 3-8% in either direction. On a $5 million deal, that's up to $400,000 that can move between signing and closing without anyone changing the headline number.

The remedy is almost always the same: get an advisor who has actually negotiated working capital pegs to review the draft LOI. Fixing the peg language before you sign takes a day. Fixing it after takes a fight. You can read more about how the mechanics work in our piece on the working capital peg that quietly shrinks your sale check - it's one of the more important things to understand before you get anywhere near an LOI.

The Business That Can't Run Without You

Key-man dependency is another deal-killer that rarely surprises anyone except the seller. Buyers want to acquire a business. They do not want to acquire what is functionally a high-paying job that happens to have some supporting staff.

If you own the key customer relationships, hold all the institutional knowledge about how the service is actually delivered, and are the reason clients renew every year - the buyer's diligence team will find that out. They'll talk to employees. They'll review renewal histories. They'll look at who is on the emails with major clients. They'll map the organizational chart and realize that chart only functions because of the person who built it. The Axial 2025 report identified seller decisions and operational dependency as recurring factors in deal restructurings, and from what I've seen with owners approaching exits, key-man risk is almost always underestimated by the seller and overweighted by the buyer.

The result is not always a dead deal. But it is almost always a repriced deal. Buyers will structure more of the consideration as an earnout tied to customer retention, impose longer escrow holdbacks, or lower the overall multiple to account for transition risk. "We'll need you to stay for three to five years" is not what most sellers wanted to hear when they signed the LOI. Earnouts, as deal practitioners document extensively, appear in roughly one in four small business deals - and once an earnout is in place, disputes over the formula, the metric, and the calculation can swing payouts by 10-30%.

The preparation here is also done long before the sale process begins - ideally two to three years out. Building a management team with real authority. Documenting processes. Making sure the business has client relationships that belong to the business, not to the founder. Not because it's a legal requirement, but because a business that operates without you is worth more than one that doesn't. Considerably more. We've covered this in depth in our article on why buyers pay less when a company can't run without you - if you're within five years of a potential sale, it's worth reading before you do anything else.

When Buyers Can't Get to Closing: Financing and Structural Failures

Not every deal collapses because the seller had a problem. Sometimes the buyer runs into trouble, and the seller - who thought they were three weeks from closing - finds out that the SBA loan fell through, or the private equity sponsor's credit committee changed terms at the last minute, or the strategic acquirer's board revised the acquisition thesis. According to Axial's analysis, financing constraints caused 10.7% of broken LOIs in 2025. That may sound modest compared to diligence issues, but in practice it represents deals that were otherwise clean - sellers who did everything right and still lost the transaction.

SBA-financed deals are particularly vulnerable. The SBA has its own appraisal and underwriting requirements, and those requirements sometimes produce a lower enterprise value than what the LOI established. One searcher's detailed account of a failed Alaskan tour operator acquisition documents how the selected lender - chosen specifically for its Preferred Lender Partner status, which was supposed to speed the process - pushed the loan into the SBA's General Partner approval process anyway, introducing a 4-6 week delay that ultimately contributed to the deal dying. The estimated cost to the buyer: $40,000 in sunk diligence expenses, plus months of opportunity cost. The lesson from that experience: understand your buyer's financing structure before you sign an exclusivity agreement, not after.

Strategic buyers - companies acquiring your business - can run into integration approval issues. Their board signs off on an acquisition and then the CFO's team runs the detailed integration model and says the numbers don't work at that price. Or the market shifts. Or their own quarterly results create internal pressure to pull back on M&A. The Axial 2025 report documented a deal that fell through specifically because of the tariff situation - the seller had done nothing wrong; the macro environment moved under the deal. These are the risks sellers can't control, which is why structuring a break-up fee or reverse termination fee for material financing failures is worth negotiating at the LOI stage.

The Reps and Warranties Fight and How It Ends Deals

Representations and warranties - the contractual statements that both sides make about the condition of the business - are where a lot of deals get slow-walked to death. Sellers represent that the financials are accurate, that there's no undisclosed litigation, that key contracts are assignable, that the business is compliant with applicable law, and dozens of other things. Buyers negotiate survival periods, indemnification baskets, and liability caps. When those negotiations get contentious - which happens when either party's attorney tries to fight over every provision - deals die not from a single dispute but from accumulated fatigue and broken trust.

I've seen transactions where both parties would have been better off closing at the original terms, but six weeks of rep and warranty fighting left everyone exhausted and suspicious. The business continued operating, the buyer continued looking at other deals, and one day someone decided it wasn't worth the fight. Renegotiation challenges accounted for 14.7% of broken LOIs in the Axial analysis - and in my experience, attorney-driven escalation is behind a meaningful portion of those.

The solution is having advisors who know what's standard and fight for what actually matters. Experienced M&A counsel on both sides produces better outcomes than general business attorneys treating every provision as a negotiating position. And sellers who understand what they're actually representing - rather than signing off on documents they haven't read - are far better positioned to close cleanly.

How to Get from LOI to Closing

Getting across the finish line requires a few things that don't come automatically. A clean virtual data room - organized, complete, responsive - that doesn't force the buyer's team to make the same request three times. An advisor who is actively managing the process, not just answering questions as they come in. And an owner who is mentally prepared for the diligence period to feel like a forensic audit of their professional life - because it is.

The emotional dimension doesn't get talked about enough. Sellers are often genuinely surprised by how personal due diligence feels. Someone is combing through everything you've built, looking for problems. That's the buyer's job. As one deal practitioner put it, acquisition deals "want to die" - they are trains looking to jump the tracks, and time is the enemy. The best thing a seller can do is make diligence easy by not having hidden problems to find, and working with advisors who have done this enough times to keep the process from becoming a referendum on your competence.

One more thing: deals die when they slow down. The longer a transaction takes, the more chances the market has to shift, the more chances the buyer's team has to second-guess, and the more chances the seller has to develop cold feet. Once you've signed an LOI, the goal is to close. Everything else - the data room, the representations, the working capital negotiations - is in service of that goal. Don't lose sight of it.

What Will Matter Most for Business Sellers in the Next 12-24 Months

The middle-market M&A environment in 2025 and 2026 is not the frictionless seller's market that some owners have been planning for. Private equity deal activity has been bifurcated: top-tier assets are still attracting competitive processes, while a long tail of other businesses - perfectly good companies with real revenue and real profits - are struggling to transact at the multiples owners expected. A healthcare private equity panel from mid-2025 described it plainly: there are "haves and have-nots," and the deals that aren't getting done often aren't getting done because the assets haven't been prepared the way buyers now require them to be.

Here's what I'm watching for clients who are approaching an exit window in the next one to two years.

Diligence standards are rising, not falling. The shift from QoE EBITDA discrepancies being the primary broken-LOI driver in 2023 toward non-QoE diligence findings claiming that top spot in 2025 tells me buyers are looking harder and broader than they used to. Environmental, legal, regulatory, and operational findings are now as likely to kill a deal as a financial restatement. Sellers who did a rigorous pre-sale financial cleanup but ignored the operational or compliance side will find themselves surprised in the same way their predecessors were surprised by QoE. The diligence is more comprehensive now. Prepare accordingly.

Earnout usage is increasing. When sellers and buyers can't agree on price, earnouts are the tool buyers reach for to bridge the gap. In rising-uncertainty markets - tariff disruptions, interest rate adjustments, sector-specific headwinds - buyers are using earnouts not just to reward future performance but to shift risk back to sellers. For a seller, an earnout means your proceeds depend on the business performing under someone else's management. Understanding exactly how earnout metrics are calculated, and negotiating those terms before you sign the LOI rather than in the purchase agreement, is increasingly important.

Financing conditions matter more than they did. SBA and bank financing for small business acquisitions became more expensive as interest rates rose. More expensive financing means buyers model lower values at the same debt service, which compresses purchase price multiples for deals in the $1M-$5M enterprise value range. Sellers who are targeting this buyer pool - first-time acquirers, self-funded searchers - should be aware that their buyer's financing risk is also their risk. Understand the debt structure before you grant exclusivity.

Representations and warranties insurance is becoming standard. R&W insurance - which allows buyers to insure against seller rep breaches rather than relying solely on seller indemnification - is increasingly common in deals above $10M in enterprise value and is beginning to appear in smaller transactions. For sellers, it can shorten escrow holdback periods and limit post-closing exposure. Understanding whether your deal structure contemplates R&W insurance, and what it costs and covers, is worth the conversation with your M&A attorney before you get to the negotiating table.

The common thread in all of these is preparation time. Each of these dynamics rewards sellers who start planning two to three years before their target exit, and punishes sellers who assume the market will look the same in eighteen months as it did when they first started thinking about selling.

Selling a business is the largest financial transaction most owners will ever do. Getting from LOI to closing requires more than a good business and a willing buyer - it requires preparation that starts years before the sale, advisors who have actually done this before, and an honest accounting of the risks that tend to surface when someone else starts looking at your books. The owners I've seen close cleanly are the ones who did the work early: understood what a QoE would find, addressed it, built a management team, and walked into diligence with nothing to hide and a data room ready to go.

That's not luck. It's preparation. And as an independent, fee-only fiduciary advisor who specializes in helping business owners coordinate their exit planning with their personal financial picture, I think it's one of the highest-value things we do for clients. If you're considering a sale in the next three to five years, the time to start that conversation is not when you have a buyer in front of you. It's now - while there's still time to fix what diligence would find.
