The 35% Turnover Problem PE Diligence Doesn't Catch
The QofE came back clean. Revenue trending up. EBITDA margins defensible. Commercial diligence confirmed the market. Legal found nothing unusual.
Six months later, the acquirer had to bring on a new CEO, CFO, and CRO. Within 18 months, 35% of the workforce had turned over. The value creation plan — underwritten to a specific team executing specific initiatives — was dead on arrival.
Everything financial looked perfect. The human capital side fell apart post-close.
This isn’t a one-off horror story. It’s a pattern. It keeps repeating because the diligence process was designed to validate numbers — and the numbers were fine. The people behind the numbers weren’t part of the equation.
The Predictable Sequence Nobody Predicts
Here’s how this plays out. Not sometimes. Routinely.
Month one: new owners introduce reporting requirements. Weekly KPI decks. Board-ready dashboards. Monthly operating reviews. For a team that’s been running on gut feel and quarterly P&L reviews, this feels like surveillance.
Month two to three: key operators start questioning the change. They’ve been doing this for years. It worked. Now someone who’s never walked the production floor is asking them to justify decisions in a format they’ve never seen. The hallway phrase: “This isn’t what I signed up for.”
Month four to six: the first departures. Here’s what stings — it’s not the underperformers who leave first. It’s the ops manager who has every customer’s number in her phone. The controller who built the reporting from scratch. The sales lead who personally manages the top 20 accounts. These aren’t interchangeable resources. They’re the business.
Month six to twelve: the scramble. External hires who don’t know the culture, the customers, or the quirks. Onboarding that takes months. Cultural friction between the new guard and whoever stayed.
Month twelve to eighteen: finally stabilized. But you’ve burned twelve-plus months of value creation runway. The hold period didn’t get longer.
One PE operator described the experience bluntly: “Had 35% turnover within 18 months. It was incredibly painful.”
Painful is the right word. Not just the $300K to $500K in replacement costs. Painful because you’re watching the business you underwrote disassemble itself while the deal model sits untouched on the server.
Why Your DD Process Misses This
The reason financial diligence doesn’t catch human capital risk isn’t negligence. It’s design. The DD stack was built to answer financial and legal questions, and it answers them well.
Quality of Earnings asks: Are these earnings real? It does not ask: Who creates these earnings, and what happens if they leave?
Commercial diligence asks: Is the market growing? It does not ask: Can this team capture that growth, or does revenue depend on three relationships held by people who haven’t been consulted about the transition?
Key person risk shows up in every CIM. Every deal memo has a line about it. But it’s a checkbox, not a workstream. It gets noted, not validated. Nobody stress-tests the org chart. Nobody interviews the second tier of leadership to assess bench strength, flight risk, or change tolerance.
Deal assumptions and operational reality diverge precisely here — in the gap between acknowledging that people matter and actually assessing whether they’ll stay.
There’s a structural incentive problem too. Deal teams want to close. Every additional workstream is friction. When your incentive is to get to signing, you’re not going to volunteer a process that might stop you.
The result? As one industry practitioner observed, “The management team kept telling you that performance was improving… Adj EBITDA came in lower than expected.” By the time the numbers confirm what the org chart would have predicted, the talent is already gone.
Five Data Points That Predict Post-Close Turnover
You don’t need a $200K consulting engagement to assess human capital risk. You need five things no standard DD workstream covers.
Tenure distribution. Pull the tenure data for every person in a leadership or key operational role. Half your management team under two years? That’s a signal. Average tenure of fifteen years with zero transition experience? Different signal — they’ve never had to adapt to new ownership, and you’re about to find out if they can.
Single points of failure. Who holds the customer relationships? Who knows the vendor pricing? Who has the passwords, the tribal knowledge, the institutional memory? In most lower middle market companies, the answer is two to four people. Existence does not equal utility — the org chart shows you roles, but it won’t tell you who actually makes the business run.
Change readiness. Has this team survived a significant transition before? Ownership change, major system implementation, restructuring? Teams that have navigated change are dramatically more likely to handle PE ownership. Teams that haven’t are flying blind — and so are you. Ask long-tenured employees: “What’s the biggest change this company has been through?” If the answer is “nothing, really,” that tells you everything.
Compensation benchmarking. Are key people underpaid relative to market? In founder-led businesses, this is common. The founder kept payroll tight, loyalty kept people in place. Post-close, recruiters start calling with better offers, and your new reporting requirements reveal to employees exactly how their comp compares. If your best people are 20% below market, you’re funding someone else’s recruiting pipeline.
Management depth. If the GM left tomorrow, who runs the business? If the answer is “nobody” or “the GM’s assistant, kind of,” you don’t have a management team. You have a single point of failure with a title. When roughly four in ten day-one CEOs don’t survive past year two, assessing who’s behind the CEO isn’t optional — it’s the difference between a transition plan and a fire drill.
What to Add to Your DD Process
This doesn’t require inventing a new discipline. It requires adding a people lens to what you already run.
30-minute interviews with the layer below the C-suite. Talk to the five to ten people who actually run the operation. Not the CEO’s version of how things work — the operator version. Ask: “If you could change one thing about how this business operates, what would it be?” The answer tells you where the pain is, what’s been festering, and how this person thinks. It also signals to them that new ownership might actually listen — which is itself a retention tool.
Org chart stress test. Remove any one person from the chart. Does the business still function? Who steps in? Is there documentation, or does the knowledge walk out the door? Where you find no backup, you’ve found your risk. This is the same operational DD gap that financial diligence can’t fill — but it takes hours, not weeks, to identify.
Retention risk scoring. Flight risk times business impact. High on both equals immediate attention. This isn’t complex analytics. It’s a conversation-informed assessment that gives you a prioritized retention list before close.
100-day people plan. Before close, know: Who are you promoting? Who are you retaining with new comp or equity? Who might need replacing, and what’s the search timeline? Your value creation plan has financial targets for day 100. It should have people targets too.
Vern Davenport, Partner at QHP Capital, frames the retention question differently: “The secret sauce to every great company is an aligned and engaged middle management team.”
That’s the layer most DD processes skip entirely. You assess the CEO. You assess the financials. You don’t assess the middle managers who actually translate strategy into execution — and who will be the first to disengage if the transition feels like it’s happening to them rather than with them.
The cost of this work? $10K to $20K during DD. The cost of skipping it? $500K-plus in replacements, twelve months of stalled value creation, and a plan that needs rewriting before the ink dries.
One veteran PE operator summed it up: “Identify the important folks early.” Early means during diligence, not at the first board meeting. By then you’re reacting. The point is to stop reacting and start anticipating.
The Real Question
Most DD processes answer: What is this business worth?
The better question: Who makes this business worth what you’re paying for it?
If you know the EBITDA but don’t know who creates it, you haven’t done diligence. You’ve confirmed a number.
Do you know who creates the EBITDA? Not which line items — which people. Which relationships. Which institutional knowledge. If you can’t name them, your value creation plan has a gap no financial model will catch.
