The end of an earnings season can be a great time to discover new stocks and assess how companies are handling the current business environment. Let’s take a look at how CSW (NASDAQ: CSW) and the rest of the hvac and water systems stocks fared in Q2.

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 9 hvac and water systems stocks we track reported a strong Q2. As a group, revenues beat analysts’ consensus estimates by 1.4% while next quarter’s revenue guidance was 14.3% below.

Thankfully, share prices of the companies have been resilient as they are up 6.1% on average since the latest earnings results.

Market Update

The Fed’s interest rate hikes throughout 2022 and 2023 have successfully cooled post-pandemic inflation, bringing it closer to the 2% target. Inflationary pressures have eased without tipping the economy into a recession, suggesting a soft landing. This stability, paired with recent rate cuts (0.5% in September 2024 and 0.25% in November 2024), fueled a strong year for the stock market in 2024. The markets surged further after Donald Trump’s presidential victory in November, with major indices reaching record highs in the days following the election. Still, questions remain about the direction of economic policy, as potential tariffs and corporate tax changes add uncertainty for 2025.
