Metrics & tracking

The KPIs buy-side teams should be tracking — and why most aren't

Most M&A teams measure something. Few measure the right things, at the right times, with the right owners. Here's a framework for closing the gap.

On Wednesday, our CPO Vil and project manager AP walked through a practical KPI framework across the full M&A lifecycle. If you missed it, the recording is available on demand. But if you want the thinking behind it, read on.

The state of M&A performance

80%

of acquisitions fail to deliver on projected value

60%

of acquirers skip a rigorous post-year-one review

phases where most teams are consistently under-measuring

Why measurement fails in the first place

Before getting to the KPIs themselves, it's worth naming the failure modes we see most often. The first is vanity metrics — tracking things like raw pipeline volume that look impressive in a slide deck but don't drive any actual decisions. The second is siloed ownership, where someone owns sourcing, someone else owns execution, and no one owns the end-to-end story. The third is the look-back gap: most teams stop reviewing acquisitions around the twelve-month mark — right when the real results are starting to emerge.

If your CEO asked how your last three acquisitions are performing, would you, your CFO, and your integration lead all give the same answer? For most teams, if they're honest, the answer is no.

The three-phase framework

Vil & AP organized the M&A lifecycle into three distinct measurement phases. Each has its own set of KPIs and, importantly, its own common failure points.

KPI framework

What to measure — and when

Phase 1

Sourcing & Pipeline — Are you building the right deal flow?

Pipeline coverage ratio

Qualified deal value by stage probability vs. annual target. Below 3.2× is a warning sign.

Proprietary vs. third-party sourcing

Internal deals typically cost less. Tracking the mix matters for acquisition economics.

Pipeline aging & drop-off

What percentage of deals haven't moved stages in 90–180 days?

Target engagement velocity

Time from first outreach to NDA, NDA to LOI, and so on. Outliers often signal a deal going sideways.

Thesis-to-target conversion

Of your investment theses, how many produce a qualified target within 12–24 months?

Phase 2

Execution & Closing — Are you being efficient and disciplined?

Deal cycle time by stage

Especially for repeat acquirers. Deviations expose bottlenecks and capacity issues.

Cost per deal closed

Track this alongside cost per deal evaluated and cost per deal in diligence.

LOI-to-close conversion

High performers sit between 55–70%. Below that, you may be over-cautious. Above 80%, you're likely leaving moves on the table.

Diligence accuracy score

Post-close comparison of diligence findings vs. 12/24/36-month actuals. Your calibration tool for future deals.

Price discipline metric

Compare closing multiple to initial offer. Were adjustments warranted? Could they have been avoided?

Phase 3

Value Realization — Are the deals actually working?

Synergy realization rate

Actual vs. projected, tracked quarterly for 24+ months. Not 12.

Deal ROI vs. base case

Actual returns vs. approval-stage projections at years one, two, and three.

Key talent retention

Check at 6, 12, and 24 months. Early attrition is often a leading indicator of integration failure.

Customer retention / NRR

Compare post-close trajectory to pre-close. Integration-driven churn frequently shows up two or three quarters after close.

Time-to-value milestones

Hard dates for systems integration, first cross-sell, and specific synergy checkpoints.

Key takeaways (and two things that matter more than the rest)

If we had to pick the two KPIs most teams should start with immediately, it would be these.

Pipeline coverage ratio gives you a simple, honest signal on whether you're likely to hit your deal targets — before it's too late to do anything about it. A sourcing problem and a closing problem look identical on the surface but require completely different responses. This metric tells you which one you actually have.

Don't combine cost and revenue synergies. They realize at different rates, they signal different things, and blending them hides the information you need. Cost synergies typically track to plan later, as execution completes. Revenue synergies show up in customer behavior earlier. Report them separately.

Key takeaways

Three things to take back to your team

01

Cover the full lifecycle

Most teams under-invest in sourcing metrics and almost entirely abandon value realization tracking after year one.

02

Don't stop at year one

The first anniversary is when reviews typically end. It's also when results are just beginning to emerge. Aim for at least 36 months.

03

Cut the vanity metrics

If a KPI doesn't change behavior or drive a decision, it's noise. Every metric needs a named owner, a consistent formula, and a reporting cadence.

One final note on reporting cadence: board-level reporting works best quarterly, executive teams monthly, and deal teams weekly or even daily. Different stakeholders need different granularity — don't send everyone the same report.

Watch the full session on demand; Vil and AP go deeper on these KPIs with examples and questions from the attendees.
