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 at the end of Q1 2026 and pushed 2026 revenue growth guidance to ~40%-45%. Q2 2026 went further: revenue of about $627 million was up roughly 101% year over year, net income rose to about $57 million, and EPS of $0.69 beat a consensus near $0.49, the second straight sizable beat. 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. The share price has not followed the results: at about $75.01 on October 16, 2026 the stock was down about 25% over one year and about half its 52-week high of roughly $150, for a market value near $6.2 billion. Heavy investment also turned free cash flow negative (about -$214 million trailing), funded with roughly $450 million of debt.

Valuation remains a central risk even after the multiple fell: AAON trades near 39x trailing earnings, and the stock's roughly 29% drop over three months to mid-October 2026, despite a strong Q2, shows how sharply sentiment can compress the price. Oppenheimer trimmed its target to $115 from $125 in October while keeping an Outperform rating. 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. Negative free cash flow during the capacity build adds balance-sheet sensitivity, with about $452 million of debt and minimal cash on hand at June 30, 2026.

A price target is what an analyst published on a date, not a prediction, and sell-side ratings skew positive across the whole market.

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 remains a central risk even after the multiple fell: AAON trades near 39x trailing earnings, and the stock's roughly 29% drop over three months to mid-October 2026, despite a strong Q2, shows how sharply sentiment can compress the price. The most pessimistic target, $110.00, is roughly what AAON is worth if this bites instead.

Yes. AAON, Inc. (AAON) has had one share split in the last 10 years:

• 3:2 on August 17, 2023, so every share held became 1.5 shares.

A split changes the share count and the price per share and leaves the value of a holding unchanged. Someone holding $1,000 of AAON the day before the 3:2 split held $1,000 the day after, in more shares at a proportionally lower price. Historical prices from before the date are normally shown split-adjusted, which is why a long-run chart shows no cliff.

Splits matter mainly because they make older price figures confusing to compare by hand, and because a board choosing to split is usually signalling that the price has run up far enough to feel awkward for smaller buyers. Neither is a reason to buy or sell.

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): ~$1.93B
• Q2 2026 revenue: ~$627M (+~101% YoY)
• Q2 2026 EPS: ~$0.69 vs ~$0.49 consensus; net income ~$57M
• Margins (TTM): gross ~25.6%, operating ~11%, net ~8%
• P/E (trailing / forward): ~39x / ~21x
• Market cap: ~$6.2B (stock ~$75)
• Dividend yield: ~0.5% ($0.40 a year)

The multiple has come down hard: trailing P/E near 39x is well below the 90x-plus of mid-2026, because earnings rose sharply while the share price fell. The forward multiple near 21x assumes 2027 EPS of about $3.57, so the data center cooling ramp still has to deliver. Gross margin near 25-26% reflects ongoing capacity ramp costs, and the four covering analysts' mean target near $135 sits far above the current price.

Other names that sit close to AAON: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get AAON exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so AAON sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where AAON fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

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. By October 2026 the multiple had already compressed to about 39x trailing and 21x forward earnings, so the market is now asking for proof that the BASX ramp keeps converting into profit; Q3 results are expected around November 5, 2026.

Whether AAON is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is AAON a buy or a sell?, and where the stock could go from here in the AAON stock forecast.
