SPX Technologies: Strong Execution vs. Full Valuation – A Wait-and-See Moment

What happened

SPX Technologies reported robust Q1 2026 results with 17.4% revenue growth and raised full-year guidance, driven by data-center cooling demand and Canadian acquisitions. However, the stock trades at a demanding 44.8x P/E, pricing in a clean execution of the HVAC backlog conversion and margin expansion. The DeepValue report highlights that HVAC margin guidance was trimmed to 24.25%-24.75% due to start-up inefficiencies from capacity expansion, creating execution risk. While the balance sheet is strong and backlog elevated ($755.3M at Q1 end), the market may be ahead of reality, requiring proof that higher throughput will offset margin drag. The next two quarters are critical to validate whether the ramp delivers sustainable growth without margin erosion.

Implication

In the near term, the stock offers limited upside at current levels unless HVAC margins hold within the guided range and revenue growth continues. A wait stance is prudent until at least Q2 2026 results, which will show whether start-up inefficiencies are easing. If HVAC margins meet or exceed the midpoint, the bull case gains credibility; if they slip, the stock could re-rate lower. The bullish narrative around data-center cooling is already embedded, so any disappointment in execution could trigger a sharp correction. Long-term investors should look for a better entry near $210, where the risk/reward becomes more favorable.

Thesis delta

The thesis shifts from pure optimism on data-center cooling to a more cautious stance centered on execution evidence. While the underlying demand story remains intact, the elevated valuation and margin pressures from capacity expansion demand proof of profitability. Investors should now focus on quarterly HVAC margin and revenue trends rather than backlog growth alone.
