Three patterns show up across SPX's deal book — what the team buys, how it pays, and how it integrates. The patterns are the throughline; the individual deals below are the evidence.
SPX has assembled its portfolio from 18 disclosed deals since 2018, almost all sub-$200M cash tuck-ins folded directly into its HVAC or Detection & Measurement segments. Each acquisition is described in SPX's filings as a market leader in a narrow niche — dampers (TAMCO), obstruction lighting (Sabik, ITL), magnetic locators (Schonstedt) — then cross-sold through existing SPX channels.
Management frames acquisitions as combining into category leadership: “With the acquisitions of Sealite, Sabik, and ITL, we do believe we are the very strong global leader here, approximately $170 million,” the CEO said of Aids to Navigation. The same logic built engineered air movement (TAMCO, Ingénia, Cincinnati Fan, Strobic) and underground location/inspection (Cues, ULC Robotics, Schonstedt, Sensors & Software).
SPX funded the roll-up by exiting cyclical power-generation businesses — the 2015 spin-off of SPX FLOW, the 2016 sales of Dry Cooling and Balcke Dürr, the 2021 sale of SPX Transformer Solutions to Prolec GE, the 2020 wind-down of Heat Transfer, and the 2023 Asbestos Portfolio Sale — redeploying capital into engineered HVAC and detection franchises with better margins and growth.
