Business quality (Solid): AAON’s reported business is split across AAON Oklahoma, AAON Coil Products, and BasX, with liquid cooling a key part of BasX data center sales. Operational signals are mixed, with Organic Volume up while Net Sales Volume Decline is also reported, so investors should focus on whether volume trends and liquid cooling mix can sustain.

Valuation: At 90× earnings, AAON trades 165% above the Machinery average (34×). Note: one-time items can distort reported P/E.

Bull case

  • Liquid cooling mix embedded in data center demand: Liquid Cooling Share of Basics Data Center Net Sales is 40 percent, indicating a meaningful portion of BasX data center revenue is tied to liquid cooling products.
  • Demand signal from organic growth: Organic Volume is 23.5 percent, suggesting underlying volume growth rather than only external or non-organic drivers.
  • Capacity expansion supports future throughput: Memphis Facility Manufacturing Capacity Added is 800,000 (count), and Incremental Manufacturing Capacity Expansion (AonCoil) is 245,000 (count).

Bear case

  • Volume trend can be pressured: Net Sales Volume Decline is 5.7 percent, which is a negative signal that could outweigh organic growth depending on duration.
  • Cost structure may be sensitive to parts: Parts as a Percentage of Sales (6.6 percent) and Parts Percentage of Sales (7.0 percent) point to parts costs taking a noticeable share of revenue.
  • Mix concentration risk if liquid cooling momentum slows: If liquid cooling does not keep growing as a share of BasX data center net sales, the product mix driver implied by the current 40 percent share could weaken.
