Why Deals Fall Apart — Loss of Momentum

By Michael D. Rubin, CEO & Founder · Updated September 2026 · 718 words

Many business sales that die in the middle are not killed by price or a single bad discovery; they simply lose momentum, usually because one side has developed doubts it is not voicing. The visible reasons deals fail, such as out-of-date financials, a buyer who cannot get financing or a surprise in due diligence, get the attention. The quiet one is a slowdown nobody names until it is too late.

The good news is that momentum can be recovered if someone notices early and acts directly.

What a stall looks like

It tends to appear in the long middle of a deal, after the letter of intent and well into due diligence, when the advisors are busy with documents and nobody is watching the pace. The signs are small at first, and each alone can be innocent; a cluster of them is not:

• Calls and emails go unanswered for days, then get short replies.
• Documents promised for this week arrive next week, incomplete.
• Meetings are postponed without a new date.
• One side starts raising small new issues, each reasonable on its own.
• The advisors are busy, but the principals have stopped talking to each other.

The real causes are usually emotional

Traced to its source, a stall is rarely about something concrete, and the party affected seldom says so outright, which is what makes it hard to read. These are the usual culprits:

• Seller's second thoughts. The owner realizes, late, what life after the sale will look like, is not sure they want it, and does not know how to say so.
• Buyer's doubts. The buyer found something in due diligence that worries them and has not decided whether to raise it or leave.
• Chemistry. One side has stopped trusting or liking the other.
• Fatigue. Diligence requests feel endless, and a seller still running the business every day runs out of energy.
• Outside pressure. A spouse, partner or advisor is quietly arguing against the deal.

What to do the moment you see it

Speed matters, because a stalled deal loses value every week it sits, and the longer the silence lasts, the harder the conversation becomes. The response should be direct. If the answer turns out to be that one side no longer wants the deal, it is better to learn that now than after another month of fees.

• Name it. The advisor should call the quiet party, ideally visit in person, and ask plainly what has changed.
• Separate feelings from facts. A factual issue, such as a diligence finding, can be negotiated. An emotional one, such as seller's remorse, needs a conversation about goals, not documents.
• Get the principals together. A lunch or dinner between buyer and seller, without the paperwork, often settles what weeks of emails could not.
• Reset the timeline. Agree on the remaining steps with dates and owners, and confirm them in writing.

How to keep momentum from slipping in the first place

Most stalls can be prevented. Sellers who prepare their records, their team and their own plans for life after the sale before going to market are far less likely to freeze late. A realistic schedule helps too; our article on how long due diligence takes sets expectations. Weekly calls and a shared task list, anchored to a clear sale process, keep everyone accountable. And a seller whose advisor has kept other interested buyers warm is never entirely at the mercy of one buyer's mood.

Momentum also protects the price. A buyer who senses the seller has lost energy, or who has lost energy themselves, is more likely to try to renegotiate; our guide to preventing a price retrade covers that risk.

How MDR & Associates keeps deals moving

MDR & Associates represents sellers of Texas companies with $3 million to $100 million in annual revenue, and a principal of the firm stays involved from the first negotiation to closing. We talk with owners about life after the sale at the very first meeting, so second thoughts surface early rather than in due diligence, and we run diligence against a written schedule with the owner's attorney and CPA. Owners have one point of contact throughout, so a slowdown is noticed within days rather than weeks. If you are in a deal that has slowed down, or are planning one, contact the firm.

Questions owners ask next

What if the seller is the one getting cold feet?

Address it directly and early. Many owners hesitate because they have not planned what comes after the sale. A candid conversation about their goals, their transition role and life after closing often resolves it. If the owner truly does not want to sell, ending the process cleanly is better than letting it drift.

Can a buyer walk away if a deal stalls?

Before the purchase agreement is signed, usually yes, because most letters of intent are nonbinding on the business terms. That is exactly why momentum matters: until signing, either side can leave. Check any binding provisions, such as confidentiality and exclusivity, before deciding what to do.
