The key risks to AAON (symbol: AAON) include regulatory changes related to refrigerant transitions, fluctuations in the nonresidential construction market, and margin pressure combined with accounting scrutiny within its BASX segment.

1. Regulatory Changes and Refrigerant Transition: AAON has faced significant challenges due to industry-regulated refrigerant transitions, which have created operational obstacles and negatively impacted sales and profitability, particularly in its AAON Oklahoma segment. This issue was a key headwind in 2024 and is expected to persist into the first quarter of 2025.
2. Fluctuations in the Nonresidential Construction Market: As a provider of HVAC solutions for commercial and industrial indoor environments, AAON's business is directly affected by the health of the nonresidential construction sector.
