Each record in this stretch raised the bar by a little. 2018's significance was less the number than the shape of who was setting it. This is the data; the wave it opens is the institutional-era explainer.
§ 01 · The year in contextA record built in the back half.
2018 reached 626 announced transactions (later restated to 643), a new all-time high. The unusual feature was the calendar shape: the first half cooled off the prior year's record start, but the second half surged to 330 deals — a record H2 that, on its own, would have outranked any full year before 2014. The 174-deal Q3 was the busiest third quarter on record.
| Year | Announced deals | YoY change |
|---|---|---|
| 2015 | 457 | +26% |
| 2016 | 461 | +1% |
| 2017 | 604 | +31% |
| 2018 | 626 | +4% |
§ 02 · Who was buyingPE/Hybrid nears 68%.
Capital-backed buyers pushed toward 68% of all deals — the highest share yet — while public brokers and banks slipped further. The buyer pool itself narrowed: unique buyers fell about 20% year over year, even as total volume hit a record. Fewer firms were doing more.
| Buyer type | 2016 | 2017 | 2018 |
|---|---|---|---|
| PE / Hybrid | 56% | 63% | 68% |
| Privately owned | 25% | 22% | 17% |
| Publicly traded | 9% | 8% | 11% |
| Bank-owned | 6% | 4% | 3% |
| Other | 4% | 3% | 1% |
§ 03 · The 100-deal buyerA single platform crosses the line.
The top-10 buyers closed 62% of all transactions, the highest concentration yet. The headline was a milestone: for the first time, a single capital-backed platform closed more than 100 acquisitions in a single year — better than two a week, sustained for twelve months. The platform-and-tuck-in model had reached an industrial scale that the rest of the field, including the largest public brokers, could not approach on volume.
- 626 deals, a new record. Up about 4% on 2017.
- A record second half. H2 alone outranked any full year before 2014.
- PE/Hybrid neared 68%. The highest capital-backed share to date.
- Fewer buyers, more deals. Unique buyers fell ~20% as volume hit a record.
- The first 100-deal year. One platform crossed 100 acquisitions in twelve months.
- Top-10 captured 62%. Concentration reached a new high.
Scale belongs to the buyer; value belongs to the book.
A market where a single platform can absorb 100 agencies a year is one where the most active buyers operate like assembly lines — fast, repeatable, and selective. Two implications for a seller: process readiness matters more as buyers industrialize, because a platform running at that cadence rewards clean books and penalizes diligence surprises; and the buyer set is small and knowable, which is why reaching it through structured access beats hoping to be found. A buyer's scale sets the pace of the deal; your fundamentals set its price.
The peak that precedes it is the 2017 summary; the pre-pandemic high that follows is the 2019 summary.

Restatement. 2018 was reported as 626 and later restated to 643 as late deals surfaced. Counts revise upward over time; cross-report comparisons carry small drift.
Recaps excluded. Sponsor-to-sponsor recapitalizations are not counted as transactions.
