nVent Electric closed a $1.75 billion acquisition Monday that makes data center infrastructure its third operating pillar alongside enclosures and thermal management. The London-domiciled company, run from St. Louis Park, did not name the target in initial releases but confirmed the deal expands its liquid cooling and power distribution footprint for hyperscale and enterprise facilities. This is the third data center asset buy in eighteen months.

The company reported $2.9 billion in trailing revenue before the close, meaning this single transaction represents 60 percent of the existing revenue base. Management guided to $450 million in incremental annual revenue from the acquired assets, with 22 percent EBITDA margins at stabilization. Integration costs are pegged at $85 million over two years, half of which hits in 2025. nVent used a $1.4 billion term loan and $350 million in cash, preserving its revolving credit facility.

The deal changes the portfolio mix. Data center revenue was 11 percent of the total in Q3 2024. With the acquired revenue stream, that figure moves to 18 percent on a pro forma basis, assuming flat performance elsewhere. nVent's existing thermal business—Hoffman enclosures, Schroff racks—serves telco and industrial customers at lower margin. The new assets skew toward custom liquid cooling loops and modular busway systems, both of which carry 500 to 700 basis points higher gross margin than legacy enclosure sales. That spread matters because nVent's return on invested capital was 9.8 percent in the last fiscal year, below the 12 percent cost of capital most allocators use for industrial cyclicals.

Operators should watch three levers. First, nVent's backlog disclosure in the Q1 2025 earnings call, expected late April. Management has not quantified the acquired backlog, but hyperscale buildouts typically carry nine to fourteen month lead times from contract to installation. Second, any announced divestitures in the legacy electrical portfolio. The company has $720 million in slower-growth commercial construction exposure that no longer fits if data center becomes the valuation anchor. Third, pricing discipline on the acquired contracts. Liquid cooling deals signed in 2023 and early 2024 reflected tight supply and 12 to 18 percent annual escalators. New contracts signed in late 2024 show 6 to 9 percent escalators as capacity comes online from domestic and Chinese suppliers.

The company now sits between vertically integrated players like Vertiv, which makes the whole rack, and component specialists like nVent's former peer set. That middle position works if hyperscalers want a systems integrator for thermal and power but not a full-stack provider. It fails if customers pull integration in-house or if Schneider and Eaton expand their own liquid cooling platforms through acquisition. nVent's next earnings call will clarify whether the acquired contracts are sole-source or shared across multiple thermal vendors. The difference is $140 million in annual revenue risk if three-year deals come up for rebid in 2026.
