Infrastructure Investment Tailwinds Drive Flow Control M&A Strength
Capstone Partners’ latest Flow Control Sector Update reports that the sector has found itself in concurrent demand cycles that have reshaped capital allocation across the Industrials landscape. The closure of the Strait of Hormuz in late February 2026 has triggered the most severe oil supply disruption in the 21st century, resulting in an urgency to accelerate alternative supply infrastructure such as pipelines, liquified natural gas (LNG) terminals, and domestic production capacity. The current run-rate has suggested sector merger and acquisition (M&A) activity will expand for a second consecutive year, supported by resilient industrial demand and infrastructure investment.
Flow control M&A activity has risen to 62 transactions through year-to-date (YTD) 2026 from 46 in YTD 2025, reflecting continued upward momentum following a softer 2024 which saw deal volume drop 34.8% year-over-year (YOY). Buyer composition has remained relatively balanced, with private strategics accounting for 27.4% of transactions in YTD 2026, up modestly from 21.7% in YTD 2025, illustrating steady appetite for acquisitions that expand product breadth and geographic reach. In contrast, public strategic participation has equaled the prior year period with 11 deals to date, though share has declined to 17.7% from 23.9% in YTD 2025 as larger corporates have prioritized balance sheet discipline and organic initiatives. Private equity (PE) add-ons have led activity to date at 24 deals versus 18 deals in the prior period, reinforcing ongoing sponsor conviction in platform scaling strategies. Platform formations have remained largely unchanged, with volume up a modest three deals YOY. The fragmented nature of the Flow Control M&A landscape has supported elevated consolidation activity, with both private strategics and financial sponsors competing actively for differentiated assets throughout the value chain.
Gigawatt (GW)-scale data centers and gas-fired additions have provided the near-term supply for rising power demand, yet the same load growth has revived Nuclear Power, a long-dormant end market that has carried the highest flow control content of any energy generation source. Nuclear power’s distinct requirements for precision, redundancy, and multi-decade reliability have repositioned the reactor supply chain from a decommissioning narrative into one of the Flow Control sector’s most durable growth themes. That backdrop has inflected sharply. Hyperscale technology companies have collectively committed to more than 11 GW of new nuclear capacity to power artificial intelligence (AI) data centers, while the U.S. Department of Energy (DOE) has deployed over $17.5 billion since 2020 across advanced reactor, fuel, and loan programs, according to the DOE. This appetite has been most evident in Flowserve’s (NYSE:FLS) February 2026 acquisition of Trillium’s Valves Division (TVD), a transaction that has become a defining illustration of consolidation across the Valve market and the premium buyers have continued to assign to nuclear-grade assets ($490 million, 2.5x EV/Revenue and 12.3x EV/EBITDA). The theme was reinforced several months later when Électricité de France (EDF)-backed Framatome acquired Trillium’s French Nuclear Valve business, underscoring growing strategic demand for scarce, nuclear-qualified flow control capabilities (June 2026, undisclosed).
