AAON Inc (NASDAQ: AAON) shares soared 5.18% in pre-market trading on Thursday following the release of its first-quarter 2025 financial results, which significantly exceeded analyst expectations.

The heating, ventilation, and air conditioning (HVAC) company reported earnings per share (EPS) of $0.35, surpassing the analyst consensus estimate of $0.27 by an impressive 29.63%. While this represents a 23.91% decrease from the $0.46 per share earned in the same period last year, the better-than-expected performance appears to have buoyed investor sentiment.

AAON's quarterly sales also outperformed, coming in at $322.05 million, beating the analyst consensus estimate of $289.16 million by 11.38%. This figure represents a robust 22.87% increase over the $262.10 million in sales reported for the same quarter last year. The company's strong top-line growth, despite challenging year-over-year comparisons, demonstrates its ability to expand market share in the competitive HVAC industry.

The company's gross margin for the quarter stood at 26.8%, while operating income reached $35.111 million. These figures, along with the revenue and earnings beats, suggest that AAON has been able to navigate supply chain challenges and inflationary pressures effectively. Investors appear to be rewarding the company's resilience and growth prospects, as reflected in the pre-market stock price surge.
