When Bolt-Ons Are a Growth Strategy, Integration Should Be a Capability

An article by Carpedia International executives Carl Valentino and Jacques Gauthier argues that private equity firms have become highly effective at building repeatable acquisition models, but are less systematic about what happens after closing. The article draws on the Bolt-On Integration Benchmark Study conducted by Carpedia International and Private Equity Professional. In that study, 77% of respondents said bolt-ons are either a core growth strategy or an important part of one, and only 7% characterized them as opportunistic. The authors contend that as acquisition cadence rises, the central question shifts from completing individual deals to whether the platform has a reliable way to integrate each new business without rebuilding its approach from scratch.

The authors distinguish between an integration plan, which organizes the work for a single acquisition, and an integration capability, which captures the know-how, routines, decision rights and management discipline that improve the organization's performance on the next deal. Nearly 60% of study respondents said integration responsibility sits with portfolio company leadership. The authors view this as reasonable because portfolio leaders understand the customers, employees and commercial realities of the business, but they warn that decentralizing responsibility without a repeatable framework causes much of the learning from earlier deals to be lost.

According to the study, cultural resistance was the most frequently cited challenge at 30%, followed by systems and data integration at 28% and conflicting operating processes at 23%. The authors note these issues often appear as separate workstreams but overlap in practice. They also cite an unnamed construction-services company with five operating companies still on legacy processes, where Carpedia worked with functional leaders to design aligned future-state processes while preserving differences that mattered in individual markets. On technology, more than half of respondents favored gradual harmonization after a bolt-on, while 17% pursued immediate migration. The authors argue that operating decisions should generally lead technology decisions.

The study found that operating efficiencies and SG&A were the largest sources of unrealized synergy, accounting for nearly 65% of responses. Nearly every respondent reported realizing at least some anticipated operational improvements, but 53% said full improvements were achieved only sometimes or rarely, compared with 47% who said they were achieved frequently or almost always. The authors conclude that firms pursuing buy-and-build strategies should develop integration capability with the same rigor applied to sourcing and diligence, including stronger governance, clearer operating measures and a disciplined process for capturing lessons from each acquisition.
