As the craze of earnings season draws to a close, here’s a look back at some of the most exciting (and some less so) results from Q2. Today, we are looking at hvac and water systems stocks, starting with Northwest Pipe (NASDAQ:NWPX).

Many HVAC and water systems companies sell essential, non-discretionary infrastructure for buildings. Since the useful lives of these water heaters and vents are fairly standard, these companies have a portion of predictable replacement revenue. In the last decade, trends in energy efficiency and clean water are driving innovation that is leading to incremental demand. On the other hand, new installations for these companies are at the whim of residential and commercial construction volumes, which tend to be cyclical and can be impacted heavily by economic factors such as interest rates.

The 8 hvac and water systems stocks we track reported a strong Q2. As a group, revenues beat analysts’ consensus estimates by 2.3%.

Inflation progressed towards the Fed’s 2% goal at the end of 2023, leading to strong stock market performance. On the other hand, 2024 has been a bumpier ride as the market switches between optimism and pessimism around rate cuts and inflation. Thankfully, hvac and water systems stocks have been resilient with share prices up 7.9% on average since the latest earnings results.
