Winston Score History

The full picture

AAON, Inc. makes heating, ventilation, and air conditioning (HVAC) equipment — basically the large units that keep commercial buildings comfortable. Its main products are rooftop units, chillers, and air handlers sold to schools, hospitals, offices, and retail stores across the United States and Canada. AAON is known for manufacturing nearly all of its own components in-house, which is unusual in the HVAC industry.

AAON earns money by selling its equipment directly to contractors and mechanical engineers who specify it for construction projects. The company operates primarily out of manufacturing facilities in Tulsa, Oklahoma, and Longview, Texas, and generates roughly $1 billion in annual revenue. Its vertical integration gives it more control over quality and costs than many competitors, acting as a key competitive advantage. The main growth driver is rising demand for energy-efficient commercial HVAC systems, though the business is sensitive to slowdowns in commercial construction activity, which can quickly reduce new equipment orders.

Revenue accelerating

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
