Bain’s 2026 Global M&A Report carries a data point from its prior building products analysis that does more work than its placement in the chapter suggests. Frequent and material acquirers in building products delivered 9.6% annualized total shareholder return; inactive peers delivered 2.7%. The 690 basis-point annualized gap compounds across cycles, and Bain attributes the differential to discipline — “winners invest through the cycle.” That framing is correct as far as it goes. For mid-tier PE platforms in the sector, it leaves the harder question unasked: what does the operating capacity to keep acquiring through a down cycle actually require, and why do most mid-tier platforms lose that capacity exactly when the next cycle’s premium starts to open up?
The conditions in 2025 are the conditions in which the premium has historically opened. Bain describes the construction environment as “still-fragile construction demand and an uncertain outlook.” Operating Benchmarks in the Building Materials Industry, 2024 edition, reaches the same picture from underneath, in its current-conditions reading of six federal sources through December 2025: prices off their peaks and segment-divergent, production soft for construction-tied manufacturing, residential and commercial pipelines weakening, and labor demand easing. The Bain framing and the federal-data reading agree. Exactly the inflection where through-the-cycle acquirers have, in prior cycles, captured disproportionate share of the next up cycle. The scale-to-scope rotation traced in The Scale Curve Has Run Out is the strategic shift these acquirers are now positioned to capture. The 690 bps figure is the historical measure of what positioning ahead of the next cycle has been worth. The reading that follows is what that positioning costs operationally, and why mid-tier PE platforms in particular tend to lose the capacity to deliver it.
The 690 bps gap and what it actually measures
The Bain figure is a cumulative measurement of a structural difference, not a one-cycle outperformance. Frequent acquirers do not outperform inactive peers by 690 bps in any single year; they compound a smaller advantage across multiple years and cycles. Operating Benchmarks 2024 reads that cycle reality directly out of the peer-set long history: across 27 years since 1998, fabricated metal products expanded in only 13 of them (48%), nonmetallic minerals in 18 (67%), wood products in 20 (74%), and wholesale trade in 21 (78%). Building products is a segment-divergent cyclical asset, and the cohort math Bain measures runs across roughly a dozen cycle inflections per peer industry over the long window. The compounding is what makes the gap durable, and it is also what makes the gap difficult to recover for a platform that drops out of the frequent-acquirer cohort for a single cycle. Re-entering the cohort requires rebuilding capacity that took multiple cycles to develop, and the capacity rebuild runs slower than the cycle window typically stays open.
The framing matters because the through-the-cycle discipline is usually discussed as a CEO-level choice: invest now while multiples are low, harvest later when they normalize. The framing is correct at the capital-allocation level. It is incomplete at the operating-capacity level, where the actual constraint lives.
Why through-the-cycle is harder for mid-tier PE specifically
Large strategics in building products typically maintain dedicated M&A functions with institutional buffers that survive cost cycles. The M&A team is a department; its staffing is governed by corporate policy and protected by institutional inertia. Down-cycle cuts can erode it but rarely eliminate it. Mid-tier PE platforms in building products can typically have M&A capability embedded inside the platform — integration teams that report to platform leadership, pipeline development that competes with operating-team priorities, post-merger integration playbooks maintained by the same people who run the day-to-day business. The structural vulnerability is asymmetric: the M&A capability that gets cut in a strategic’s down cycle is more easily restored than the M&A capability that gets cut in a mid-tier PE platform, because the strategic’s M&A function is institutional and the platform’s is operational.
The result is that the through-the-cycle dynamic that breaks compounding in buy-and-build breaks more decisively for mid-tier PE platforms than for large strategics. The 690 bps premium is structurally available to both kinds of acquirers. The structural vulnerability to losing it through down-cycle cuts is asymmetrically greater for mid-tier PE — and the gap shows up in the data as outperformance for the platforms whose sponsors recognize the asymmetry and discount their down-cycle cuts accordingly.
What through-the-cycle requires operationally inside mid-tier PE
The operating capacity to keep acquiring through a down cycle is not a single capability; it is a coordinated set. Integration capacity has to be maintained at staffing levels that look overhead-heavy when deal volume is low, and the staffing has to retain the institutional knowledge that PMI execution depends on — which means the people, not just the headcount, have to be preserved. M&A pipelines have to be cultivated as continuous processes, with relationship development running through quiet quarters rather than activated when deal flow picks up. PMI playbooks have to be updated through the down cycle so they don’t decay against current industry conditions. Operating cadence at both the platform and GP levels has to be structured around continuous acquisition rhythm rather than organic-only quarters.
Grant, Nilsson and Nordvall’s 2022 European Management Journal study of successful serial acquirers frames this academically: pre-merger capability has two components — expertise (individual tacit knowledge from repeated execution) and routines (organizational processes and structures) — and the elements that comprise each are “difficult to imitate or acquire” because they take many acquisitions to develop.
The mid-tier building products platforms I watched protect M&A capacity through prior down cycles treated it as an operating function with org-chart status, not as a project team activated when deals appeared — and the distinction was usually visible in the platform’s quiet quarters more than in its active ones. None of these line items survives a CFO’s down-cycle cost-cut review on its own merits. Each survives only because someone at the platform-leadership or GP level has decided the long-cycle capability investment is worth the short-cycle margin cost, and has the institutional standing to enforce that decision when the cost pressure is highest.
Building accidentally up, losing deliberately down
The asymmetry between how mid-tier PE platforms build acquisition capability and how they lose it is the structural source of the 690 bps gap. Capability tends to build accidentally during up cycles: deal flow scales integration teams, pipeline development happens through high-volume reps, PMI playbooks evolve through repeated execution. None of this requires a deliberate investment decision; the up cycle does the work. The capability tends to be lost deliberately during down cycles: integration teams get cut because they do not carry organic revenue, pipeline development gets paused because deal flow has dried up anyway, PMI playbooks get shelved because nobody is using them. Each of these decisions is rational at the moment it is made. The cumulative effect is to dismantle the capability that took the prior up cycle to build, exactly when the next cycle’s premium is starting to form.
In the building products organizations I’ve watched manage through prior down cycles, the capabilities that survived the cuts and the capabilities that didn’t determined the platform’s position when the next cycle opened — and the operating models that kept frequent-acquirer capacity intact were always more deliberate than the ones that didn’t. Long-arc leadership stewardship of operating capability through cycles where the short-term math argues for cuts is the underlying discipline. The 690 bps premium is what that stewardship is worth, measured cumulatively over multiple cycles.
The acquisition decisions nobody is calling acquisition decisions
Through-the-cycle acquisition is not a strategic posture; it is an operating discipline that has to be maintained continuously — and which platforms are positioned to capture the next cycle’s premium is being decided right now, in down-cycle staffing and pipeline and playbook decisions nobody is calling acquisition decisions.
