Quarterly earnings results are a good time to check in on a company’s progress, especially compared to its peers in the same sector. Today we are looking at AAON (NASDAQ: AAON) and the best and worst performers in the hvac and water systems industry.

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 mixed Q4. As a group, revenues were in line with analysts’ consensus estimates.

Amidst this news, share prices of the companies have had a rough stretch. On average, they are down 9.9% since the latest earnings results.

Weakest Q4: AAON (NASDAQ: AAON)

Backed by two million square feet of lab testing space, AAON (NASDAQ: AAON) makes heating, ventilation, and air conditioning equipment for different types of buildings.

AAON reported revenues of $297.7 million, down 2.9% year on year. This print fell short of analysts’ expectations by 7.1%. Overall, it was a disappointing quarter for the company with a significant miss of analysts’ EBITDA estimates and a significant miss of analysts’ EPS estimates.

Gary Fields, CEO, stated, "As we anticipated early in the year, 2024 had its share of triumphs and obstacles for AAON. The BASX brand made a significant impact on the data center market with the industry's first large-scale development and sale of a custom-designed liquid cooling solution. Along with strong demand for BASX's air-side data center cooling equipment, this drove the Company's total backlog to finish the year up 70.0% from the end of 2023. To meet a strengthening pipeline of demand beyond the backlog, we also successfully increased production capacity in 2024 with the completion of our 245,000 square foot addition at our Longview, Texas location and the purchase of our new 787,000 square foot building in Memphis, Tennessee. Conversely, the Company's AAON brand faced two major challenges: an industry-regulated refrigerant transition and nonresidential construction activity that weakened throughout the year. Despite the challenges, sales of AAON-branded equipment were down only modestly in 2024. Bookings and year-end backlog of this equipment were up year-over-year in the mid-to-high teens. All in, we deem the year to be a success."

AAON delivered the weakest performance against analyst estimates of the whole group. The stock is down 19.4% since reporting and currently trades at $82.21.
