Is Extended Due Diligence Destroying Business Exits?

Something moved in M&A deal rooms around 2023 and it hasn’t shifted back. Buyers, carrying more risk anxiety than at almost any point in recent memory, stopped treating due diligence as a confirmation exercise and started treating it as a negotiation strategy.

​

What was once a structured 60-day process is now routinely stretching past 120 days across mid-market transactions in Africa, Europe, and beyond.

​

The consequences look like deals that should close but are still stalling, founders burning out mid-process, and valuations are eroding in the exhausting weeks before anyone gets there.

​

Why aren’t advisors talking honestly enough about this crisis sitting at the centre of mid-market M&A?

 

How the Process Became the Problem

​

Due diligence was always meant to be a verification exercise. A way for buyers to confirm what sellers already know about their own businesses. But somewhere in the last two to three years, it evolved into something else entirely.

​

An extended stress test that now routinely stretches past 120 days in deals that once closed in 60.

​

No doubt, the reasons are understandable. Buyers in 2026 are carrying more risk anxiety than at almost any other point in the last decade. Regulatory environments across Africa, Europe, and emerging markets are moving faster than deal timelines can accommodate.

​

Plus, tighter capital conditions mean investors are answering to their own stakeholders with greater scrutiny. And new categories of liability (particularly around data governance, AI usage, and supply chain compliance) have added entirely new layers to what buyers feel they must verify before committing.

​

The result is a due diligence process that has transformed from a sprint into a marathon that neither side fully trained for.

 

What It Does to a Founder

​

Say you’re running a business generating R100 million in annual revenue. You’ve decided to exit, a deeply personal decision that took years to arrive at. You’ve appointed advisors, prepared your financials, and put your business forward with confidence.

Then the questions begin.

​

Hundreds of granular, consecutive data requests covering everything from your historical employment contracts to how your team uses cloud storage. Each one arrives with urgency and requires your attention, memory, your time (time you’re simultaneously supposed to be spending running the business the buyer is evaluating).

​

This is where diligence fatigue sets in and it is more dangerous than most founders anticipate.

​

 

The psychological weight of an extended diligence process is significant:

​

• Emotional withdrawal: Founders begin to mentally detach from the business they’re selling, affecting their leadership presence and decision-making throughout the process.

• Performance drift: When a business owner is consumed by document requests and legal queries, day-to-day revenue management suffers. And a dip in trading performance mid-diligence gives a buyer legitimate grounds to revisit the agreed valuation.

• Negotiation fatigue: By month four, many founders simply want the deal to be over. That desperation shifts leverage firmly to the buyer’s side, often resulting in late-stage price reductions or unfavorable commercial terms.

 

The diligence process itself has become a negotiation tool, whether buyers intend it that way or not.

​

Yet most business owners walk into a sale process believing the hard part is finding the right buyer or agreeing on a valuation. Both of those things matter but neither is typically what kills a deal.

​

What kills deals is structural unpreparedness meeting a prolonged buyer process.

​

When operational data isn’t organized for scrutiny and the business runs on institutional knowledge stored only in the founder’s head, diligence becomes an archaeological dig rather than a review.

​

And the longer that dig takes, the higher the probability that the deal quietly dies of exhaustion before it ever reaches signature.

A significant portion of mid-market deal attrition isn’t recorded as a formal breakdown. There is no dramatic moment where someone walks away from the table. Instead, momentum slows and the buyer’s team rotates.

​

Eventually, both sides accept that the deal isn’t happening without ever having a direct conversation about why.

 

The Only Preparation That Works

​

You cannot control how cautious a buyer is or shorten their internal approval processes, or reduce their regulatory obligations. What you can influence entirely is how prepared your business is before a single buyer ever opens your information memorandum.

​

Sell-side diligence, a rigorous internal audit of your own business conducted before going to market, is the most underused protective tool in the mid-market exit process.

​

Done properly, it involves:

​

• Operational documentation review: Stress-testing your own processes, contracts, and compliance records against the questions a serious buyer will ask.

• Financial narrative clarity: Ensuring your numbers don’t just add up but tell a coherent story that holds up across multiple rounds of questioning.

• Organizational dependency mapping: Identifying where the business is too dependent on the founder or a small number of individuals, and addressing that before it becomes a valuation concern.

• Data and technology risk review: In a market where AI governance and data compliance are increasingly scrutinised, understanding your own exposure before a buyer does is critical.

 

You’re not trying to make your business look better than it is. The goal here is ensuring what is genuinely strong about your business is clearly visible and defensible when a buyer is exhausted, anxious, and looking for reasons to reduce their offer.

 

Is Legacy not Worth the Preparation?

​

A deal that collapses in month four because your data wasn’t structured for scrutiny is not a bad luck story. You just prepared awfully and the cost is beyond financial.

​

Any founder who has spent decades building something meaningful knows a failed exit at the final stretch carries a weight that balance sheets cannot measure. For your exit to succeed in this environment, you simply must be prepared, regardless of how impressive the business looks on paper.
