SPX Technologies Completes CA$605M Neptronic Acquisition, Boosting HVAC Market Presence

Neptronic operates a 93,000-square-foot integrated facility in Montreal, underscoring the scale of its physical footprint beyond the reported revenue figure.
Neptronic was founded in 1976, highlighting its long-standing presence in the HVAC and controls market.
Neptronic designs and sells through a network of original equipment manufacturers (OEMs) and channel partners, indicating a diversified go-to-market approach.
SPX operates in 16 countries, underscoring the potential geographic reach Neptronic can leverage within SPX’s global platform.
SPX plans to provide updated 2026 guidance on July 30, 2026, to reflect the impact of Neptronic alongside its Q2 results.
SPX Technologies has completed its purchase of Neptronic, a Montreal-based HVAC maker, for CA$605 million — about US$430 million in cash, according to Private Capital Journal. The deal adds a 48-year-old company with roughly US$75 million in annual revenue and around 300 employees to SPX's growing heating and cooling business.
Neptronic makes intelligent controls, electric duct heaters, humidifiers, actuators, and valves. Citybiz reported the acquisition strengthens SPX's HVAC portfolio and expands its reach across more channels and geographies.
Founded in 1976, Neptronic has built a strong niche in precision HVAC controls. The company operates out of a single 93,000-square-foot facility in Montreal, according to Seeking Alpha. It sells through a network of original equipment manufacturers — companies that build Neptronic parts into their own products — and channel partners.
That go-to-market model gives Neptronic wide reach without needing a large direct sales force. Its product line covers everything from smart building controls to heating and airflow hardware. GuruFocus noted the deal is designed to integrate these products into SPX's existing HVAC segment.
At US$430 million, SPX paid a price that came in modestly above its stated target range of 8 to 12 times EBITDA — a common measure of a company's earnings power. That suggests SPX saw enough long-term value to stretch beyond its usual limits. EBITDA stands for earnings before interest, taxes, depreciation, and amortization.
Investing.com reported the deal closed with customary adjustments still pending. SPX currently operates in 16 countries. The company plans to use that global reach to push Neptronic's products into new markets faster than Neptronic could have done alone.
SPX said it wants to keep Neptronic's engineering culture and speed to market intact. The plan is to layer in SPX's capital, sales channels, and operational resources — not to gut the business and rebuild it. That approach is common when buyers want growth, not just cost cuts.
Private Capital Journal reported the integration is meant to enable more intelligent, connected HVAC systems across SPX's full product portfolio. The combined business aims to lead in what the industry calls precision thermal management — controlling heat and airflow with high accuracy in buildings and industrial settings.
SPX has not yet updated its full-year financial guidance to reflect the Neptronic deal. That update is expected on July 30, 2026, when SPX reports its second-quarter results, according to Citybiz. Investors are watching closely to see how much Neptronic will add to SPX's revenue and earnings this year.
Seeking Alpha flagged the acquisition as a strategic expansion in the HVAC market. SPX trades on the NYSE under the ticker SPXC. The Neptronic deal is one of its largest moves yet in the heating and cooling space.
