Acquirers that track synergies from day 1 reach 92% success rates

Operators and investors,

Across 40,000 acquisitions studied over 40 years, 70% to 75% fail to deliver the value the buyer underwrote. Among acquirers that track synergies from day 1, 92% capture what they modeled (2026 PMI benchmarks).

That is a 20-point swing attached to a reporting habit, and it costs less to install than any other line in the integration budget.

Most integration plans I review count workstream completion: systems migrated, contracts novated, org charts published, day-1 checklist closed. Every one of those can finish on schedule while the EBITDA case goes unmeasured, because nobody converted the model's line items into a number with an owner and a weekly review.

This issue covers 4 topics:

• Why milestone tracking hides the value gap

• Why revenue synergies land at 25% to 35% of the model

• What an integration management office actually owns

• How to set the synergy baseline before close

It is also written for sponsors and operators running an integration inside a $50M to $250M platform, drawing on the post-merger integration work we run across PE-backed companies.

1. Why milestone tracking hides the value gap

A milestone plan and a value plan answer different questions:

1. The first asks whether the work happened

2. The second asks whether it produced the number in the model

A procurement workstream can consolidate 40 suppliers on schedule and deliver a fraction of the savings the model booked, because the contracts renewed at rates nobody renegotiated.

Bain's 2025 M&A research puts a figure on the discipline: serial acquirers using purpose-built integration tooling capture 23 percentage points more of forecasted synergies than acquirers without it. In the mid-market the observed lift runs near 15 points, which on a $250M deal carrying $30M of forecasted synergies is $4.5M of EBITDA that either arrives or does not.

At a 10x exit multiple, those 15 points are worth $45M of enterprise value. The tracking system costs a rounding error against that.

2. Why revenue synergies land at 25% to 35% of the model

Cost synergies capture 70% to 85% of announced value, and revenue synergies capture 25% to 35%.

That asymmetry is the most useful number in integration planning, and most deal models ignore it by underwriting both at full value. A model carrying $30M of synergies split evenly between cost and revenue is realistically worth about $19M once the historical capture rates are applied, and the $11M difference was priced into what the buyer paid.

The cost savings are more reliable because they are built into legal contracts. A duplicate ERP license canceled is money that stops leaving. Revenue synergies depend on a cross-sell motion that two sales teams have to run together while their comp plans, territories, and CRM definitions are still being merged.

I would underwrite revenue synergies at a discount and hold the deal team to the cost case. Sponsors who price revenue synergies at par are borrowing from the exit to justify the entry.

3. What an integration management office actually owns

An integration management office earns its cost by owning one artifact: the synergy dashboard that ties every initiative to a line in the model, with a named owner and a run-rate figure updated weekly.

The review cadence matters more than the tools you use. A monthly review gives an initiative 4 weeks to drift before anyone sees it, and integration windows are short enough that 4 weeks of drift on 3 initiatives consumes the quarter. A weekly value review catches a shortfall while there is still budget and attention to correct it.

The baseline needs to be locked before close. Without a frozen pre-close cost base, every miss gets explained by market conditions, and the argument is unfalsifiable because the comparison number moved.

One point most sponsors underweight: 47% of acquired employees leave inside the first year. The people who knew why a contract was priced the way it was are gone by month 9, so the baseline has to be documented at close while they are still in the building.

The two bars explain why an integration can hit its plan and miss its model. A program weighted toward revenue synergies is carrying the harder half of the case, and the deal model rarely says so.

4. How to set the synergy baseline before close

The baseline is a diligence deliverable that needs to be locked before close; building it afterward means measuring performance against a cost base the integration has already started changing.

I advised a $180M industrial-services platform on this sequence last year. The useful output was 1 page: every synergy line from the model restated as a run-rate number, with the function that owns it and the month it starts. Finance could then report actual against modelled from month 1, and the first miss surfaced in week 6 while the supplier negotiation was still open.

Before signing, that page needs the frozen pre-close cost base by function, the synergy initiatives with owners named by role, and the month each one starts contributing run-rate, which is what turns an annual target into something a weekly review can test.

This week, pull the synergy schedule from your most recent close and put it next to the integration status report. Two questions to think about:

1. For every synergy line in the model, can we name the owner, the run-rate figure, and the month it starts contributing, or do we only have a workstream marked green.

2. What share of our underwritten synergies are revenue synergies, and what does the case look like when those are held at a 30% capture rate.

Score each answer red, yellow, or green. A red on the second question means the entry price already assumed a capture rate the historical data does not support.

🔁 CV-ready is a higher grade of exit-ready. With over 80% of GPs having run a continuation vehicle, only about 1.5 of 10 portcos can carry one, because a CV is underwritten like a company rather than a fund.

The fix for runaway AI agents is more AI. As firms hand longer tasks to agents that act faster than humans can review, the emerging answer is putting another AI in the loop to watch them, spawning a fast-growing observability market any portco deploying agents will have to buy into.

The legal ground under AI training is shifting. Unsealed filings show a Microsoft exec privately called AI scraping the largest theft of labor in human history, with Copilot cutting click-throughs to source sites as much as 93%, a content-supply and copyright risk for any portco built on scraped data or AI-generated content.

AI is compressing back-office services. A former accountant built Tabby to turn bookkeeping into a monthly utility, already on 5,500 small businesses, a signal that AI is pricing routine finance work toward zero and reshaping the economics of services portcos.

Private credit is moving up-market into investment grade. KKR structured or syndicated more than $80bn of private investment-grade financing this year, twice its full-2025 volume, with AI-infrastructure capex estimated near $7.6tn over five years as the next big source of private-credit demand.
