Leadership due diligence inside the deal timeline, and a post-close plan decided before signing
Stelios Pigadiotis | Wellman Partners
Financial and commercial diligence test the plan. The leadership team is often tested through impressions rather than evidence.
Assess leaders against the value-creation plan and turn findings into clear confirm, develop, bridge or replace decisions.
Every acquisition price assumes a plan, and every plan assumes a team that can deliver it.
Acquirers already pay for value they may not capture: McKinsey's research shows buyers typically pay a 10–35% premium while materially overestimating the synergies. Yet leadership is hard to judge informally. In AlixPartners' survey, respondents rated leadership skills and strategic thinking among the hardest competencies to assess.
1.1. Assess the target's top team against your value creation plan, not a generic leadership profile. The question is whether these people can deliver this plan.
Kaplan, Klebanov and Sorensen (Journal of Finance, 2012) studied CEO candidates in buyout and venture deals, assessing each on more than thirty abilities. Success was more closely tied to execution skills than to team-related interpersonal skills — and only marginally related to incumbency. The traits that mattered included following through on commitments, persistence and holding people accountable.
Two implications follow. Being the incumbent is not evidence of fit. And what predicts delivery can be measured before you sign.
2.1. Combine validated psychometrics with structured, competency-based interviews focused on execution: how each leader sets standards, follows through and holds others to account.
Leadership change during ownership is now the norm. Nearly two-thirds of private equity firms report replacing portfolio company CEOs during the holding period, and turnover peaks around year two — much of it unplanned and avoidable with earlier assessment. PE executives say unexpected CEO turnover lengthens the hold in 82% of cases and worsens IRR 46% of the time. Meanwhile EY finds 47% of key employees leave within the first year of an acquisition.
That is why the assessment belongs inside the deal timeline. Two to three weeks is enough to give every critical leader a clear verdict.
3.1. Build the findings into the deal: the price, retention and incentive design, and the first 100 days.
3.2. Where replacement is likely, line up bridge or interim options before signing, so the plan does not wait a year for a search.
The implication. Leadership risk found before signing is a negotiating point. Found after closing, it is a write-down.
At Wellman Partners, having assessed leadership teams inside live deal timelines, we have learned that two to three weeks is enough to give every critical leader a verdict you can act on: confirm, develop, bridge or replace. That verdict belongs in the price, the retention design and the first 100 days — not in a discussion twelve months after close, when the plan has already slipped and the options have narrowed. And because we also recruit the leaders a plan needs, bridge the gaps with interim capacity, and align and develop the team once you own it, the verdict comes with the route to acting on it rather than a list of risks to manage alone. The same assessment standard we use to settle contested appointments after a merger works before signing, where it is worth considerably more.
If you are evaluating an acquisition, I am happy to share our view on the deal.
