Shares of AAON surged +8.6% to $103.00 as the Oklahoma-based HVAC maker reported Q2 2026 revenue of $627 million — more than doubling year-over-year and crushing the Street consensus near $509 million. Analysts had expected revenue of roughly $508.82 million with EPS of $0.51. The blowout, powered by explosive demand for data-center cooling systems, cements AAON's rapid transformation from a niche heating-and-cooling manufacturer into a play on the AI-infrastructure buildout. The question now: can margins and factory capacity catch up to a backlog that keeps growing faster than the company can ship?
Revenue Doubled — and the Beat Was Historic. Q2 sales of $627 million represent 101.2% year-over-year growth and a 26% sequential jump from Q1's already-record $496.9 million. AAON had revenues of $496.9 million in Q1 2026, itself up 54.3% from the prior year. Diluted EPS rose 257.9%, meaning the profit ramp is finally outpacing the top line after quarters of margin drag. For shareholders, this signals that the heavy investment phase is starting to pay off.
Data-Center Cooling Is Now the Main Business. BASX now contributes nearly half of AAON's revenue, underpinned by a very large backlog of AI-related data center orders that reshapes the company's business mix. Liquid-cooling sales — critical for the power-hungry chips used in AI training — are accelerating. Total company backlog stood at a record $2.13 billion as of Q1, with management having already raised 2026 guidance to 40%–45% revenue growth and gross margins of 27%–28%. The fresh guidance raise after Q2 likely pushes those targets even higher, giving the stock a growth profile more typical of a tech supplier than an industrial manufacturer.
Margins Remain the Swing Factor. Near-term gross margin fell to 25.1% from 26.8% in Q1, reflecting capacity expansion costs management described as temporary. Building new factory lines and outsourcing production to keep up with orders compresses profits per unit. Any stumble in production efficiency, ERP rollout, or BASX demand could quickly pressure margins and cash flow. The EPS surge this quarter suggests efficiency is improving, but investors should watch whether margins converge toward the targeted 27%–28% as throughput scales.
Insiders Have Been Selling Into Strength. AAON insiders have traded stock 17 times in the past six months — all sales, zero purchases. That doesn't necessarily signal bearishness, but it underscores how richly the stock is now priced relative to where it traded a year ago, when ERP disruptions had shares below $82. Investors betting on AAON at $103 are buying a factory-turnaround and a data-center supercycle — both must deliver.
