AAON, Inc. (AAON) Stock Price & How to Invest

AAON, Inc. engineers and manufactures premium commercial and industrial HVAC equipment, including semi-custom and custom rooftop units, air handlers, energy recovery units, condensing units, water-source heat pumps, and controls. Its 2021 acquisition of BASX and expansion into cleanroom systems and data center thermal management turned a niche rooftop-unit specialist into a supplier of liquid-cooling solutions for AI and cloud data centers, sold under the BASX brand alongside the flagship AAON-branded product line.

The investment picture is a growth story bolted onto a stable base. AAON's traditional rooftop business is prized for energy efficiency and durability and generates steady demand tied to nonresidential construction and equipment replacement, while BASX has become the swing factor: data center cooling orders roughly doubled the company's backlog to a record ~$2.13 billion and pushed 2026 revenue growth guidance to ~40%-45%. That upside comes with a premium valuation and heavy reliance on a handful of hyperscale customers, so the story rewards continued execution on capacity expansion and margins.

Valuation is the central risk: AAON trades at a rich multiple (trailing P/E well above 70), so any growth disappointment could compress the stock sharply. The data center growth story concentrates revenue in a small number of hyperscale customers whose capital spending can be lumpy or slow if AI infrastructure demand cools. Execution risk is elevated as the company ramps new capacity, and gross margins have compressed during the ramp. The core HVAC business remains cyclical and exposed to nonresidential construction, interest rates, and input costs. Larger, better-capitalized competitors such as Vertiv, Johnson Controls, and Carrier are investing aggressively in liquid cooling, which could pressure pricing and share over time.

We give no verdict on AAON, Inc.. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Data center liquid cooling (BASX). BASX-branded sales rose ~72% year over year in Q1 2026 to ~$229 million, driven by liquid-cooling demand for AI data centers. The most optimistic published target, $154.00, assumes this works close to its best case.

The case against. Valuation is the central risk: AAON trades at a rich multiple (trailing P/E well above 70), so any growth disappointment could compress the stock sharply. The most pessimistic target, $135.00, is roughly what AAON is worth if this bites instead.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see AAON, Inc.'s investor relations page or your broker.

• Revenue (TTM): ~$1.6B
• Q1 2026 revenue: ~$497M (+54% YoY)
• Backlog: ~$2.13B (record)
• Market cap: ~$11B
• Trailing P/E: ~90x-plus
• 2026 revenue growth guidance: ~40%-45%

AAON carries a premium growth valuation, with a trailing P/E well into the double digits and a forward multiple that assumes the data center cooling ramp continues. The record backlog and raised guidance frame the bull case, while the elevated multiple leaves limited margin for error. Gross margin near ~25% reflects ongoing capacity ramp costs.

AAON pairs a durable specialty-HVAC franchise with an AI-driven data center cooling surge, and the debate is whether that growth justifies a premium multiple.
