What does it do?
AAON is a growth business that earns money by designing and manufacturing custom heating, ventilation, air conditioning, and liquid cooling systems for commercial and industrial customers. Unlike competitors who mass-produce standard units, AAON uses a "mass semi-customization" model to build equipment tailored to the specific energy and airflow needs of a building or data center. Customers pay a premium upfront for these systems because they offer lower energy costs and longer lifespans, which typically leads to a lower total cost of ownership over twenty years. Money flows from direct sales to building owners and contractors, often facilitated by a network of independent sales representatives who help engineer the solution for each project.
Where does revenue come from?
Revenue is generated across three segments focused on commercial HVAC and specialized data center cooling. The AAON Oklahoma segment is the largest, producing highly configurable rooftop units and air handlers, while AAON Coil Products in Texas builds semi-custom systems and coils. The BASX segment is the fastest-growing part of the business, focusing exclusively on high-performance cooling for hyperscale data centers and cleanrooms. Most sales occur in the United States and Canada, where the company's manufacturing footprint is concentrated.
Revenue Breakdown
Who are its customers?
AAON serves a diverse base of commercial building owners, industrial facilities, and hyperscale data center operators like those building AI infrastructure. The company reported a total backlog of $1.97 billion as of June 30, 2026, which is nearly double the prior-year level. Within this, the BASX-branded backlog for data centers grew 185% year-over-year to $1.43 billion, reflecting intense demand from tech giants and colocation providers. AAON-branded HVAC customers include schools, hospitals, and retail centers, with this segment maintaining a $540 million backlog even as production rates hit record highs. The company does not disclose individual customer names but highlights strong engagement with strategic "hyperscale" partners who require custom-engineered liquid cooling for server racks.
What gives it staying power?
Staying power comes from the Norman Asbjornson Innovation Center, a world-class lab where AAON proves its energy-efficiency claims under extreme conditions. These technical performance guarantees create high switching costs, as engineers and architects often "spec" AAON into building designs because rivals cannot match their specific dual-fuel or high-efficiency metrics.
Where is it headed?
The company is making a massive strategic bet on expanding its manufacturing capacity to become the primary cooling provider for the global AI data center build-out. Management is ramping up a major facility in Memphis to handle the overflow of BASX orders, which is expected to drive 2026 sales growth to 55-60%. If successful, AAON will move from being a regional HVAC player to a global infrastructure backbone.
Record sales growth of 101% in the latest quarter proves the company is capturing massive demand for data center infrastructure. This acceleration from $311.6 million to $627.0 million shows that the strategy of expanding capacity is working to convert a multi-billion-dollar backlog into realized revenue.
Operating cash flow improved to $55 million in the first half of 2026, marking a healthy recovery from a $31 million drain a year ago. While the company is spending heavily on new factories, the ability to generate cash while growing at 100% indicates that the underlying business model remains self-sustaining.
AAON carries a manageable $435 million in debt on its revolving credit facility to fund its rapid capacity expansion. With a debt-to-equity ratio of 0.46x and surging net income, the balance sheet provides ample room to continue investing in the Memphis and Oregon manufacturing sites.
AAON is a high-growth industrial powerhouse with exceptional top-line momentum, though it is currently navigating the temporary margin costs of scaling its factory footprint.
The BASX data center segment is growing at over 220% and has become the primary driver of the company's record $1.97 billion backlog. This growth is not just coming from a single customer but reflects a broad industry shift toward liquid cooling, where AAON's custom engineering is the gold standard.
Gross margins fell to 24.3% in the latest quarter, triggering a guidance cut as the company works through the high costs of starting up new production lines. Management must prove it can improve factory utilization and pricing in the second half of the year to bring margins back toward their historical 30% peak.
The global commercial HVAC and data center cooling market is valued at approximately $100 billion and is expected to reach $160 billion by 2030, driven by AI infrastructure and stricter energy-efficiency regulations. Pricing power is structural for custom-engineered solutions because energy costs represent the largest expense for building owners. AAON stands as a high-growth niche leader, successfully transitioning from a commercial HVAC specialist to a critical provider of liquid cooling for the world's largest data centers.
The HVAC industry is rationally structured among a few large players, but the data center cooling segment is becoming intensely competitive as AI demand surges. High technical barriers prevent standard commodity players from easily entering the custom liquid cooling market.
Vertiv is the most direct threat in the data center space, leveraging its massive scale and global service footprint to win large-scale projects. Trane and Carrier use their established brands to dominate traditional commercial buildings, often competing on the breadth of their service networks. Vertiv's ability to bundle cooling with power infrastructure represents the most significant threat to AAON's custom-only approach.
AAON is aggressively gaining market share, as evidenced by a backlog that has nearly doubled to $1.97 billion. The company's triple-digit sales growth in the BASX segment confirms it is winning the most technically demanding contracts.
AAON’s primary protection comes from its intangible assets, specifically its proprietary engineering designs and the Norman Asbjornson Innovation Center (NAIC). The NAIC allows AAON to certify equipment performance in extreme conditions that competitors cannot match, creating a technical "lock" on complex projects. The BASX backlog of $1.43 billion proves that hyperscale customers are willing to commit years of revenue to this specialized technology.
The company’s TTM ROIC of 11.5% and recent gross margin of 24.3% suggest that while the technology is strong, the business is still absorbing the heavy costs of its rapid expansion. The combination of 101% revenue growth and a $2 billion backlog proves that the company has a durable technical advantage, even if margins are currently volatile.
The Narrow rating reflects the fact that AAON is still scaling its new production capacity, and its pricing power is being tested by inflationary costs and outsourcing. While the technology is exceptional, the business has yet to prove it can maintain high margins while growing at this extreme pace.
The moat is strengthening, signaled by the 185% surge in BASX backlog which shows deepening customer reliance on AAON's custom liquid cooling. This massive backlog ensures that AAON will remain a primary supplier for AI infrastructure for years to come.
Revenue grew 101% and EPS 258% in Q2 2026, crushing analyst estimates.

Capital Allocation Track Record
Management has demonstrated exceptional strategic judgment by pivoting the company from a regional HVAC player to an AI infrastructure essential through the BASX acquisition. CEO Matthew Tobolski and his team have successfully handled a 101% revenue surge in a single quarter, proving they can scale production without the wheels falling off. Their decision to prioritize throughput and customer delivery over near-term margin perfection is the right choice for capturing market share during a once-in-a-generation infrastructure build-out.
The leadership-continuity risk is low despite the recent CFO transition, as the core engineering and strategic vision remains centered on the founders and long-term executive team. While Tobolski is a critical visionary for the BASX segment, the company has a deep bench of engineering talent and a disciplined new CFO, Andy Cheung, to manage the financial controls of a multi-billion-dollar enterprise. Board independence is strong, and the recent expansion of the board adds seasoned industrial expertise to oversee this rapid growth phase.
We expect revenue to grow from $2.1B in FY2026 to $3.7B in FY2031 (~12% CAGR), with EPS growing from $2.27 to $7.92 (~28% CAGR). Demand for specialized data center cooling systems and high-efficiency commercial HVAC units is driving a significant backlog and sustained volume growth. Profitability is improving as the company moves past a heavy investment cycle and spreads fixed factory costs over a much larger production base. EPS grows faster than revenue Operating margin expected to reach ~22% by FY2031.
Dominance in AI liquid cooling for hyperscale data centers. As AI chips generate more heat, BASX liquid cooling becomes an essential requirement rather than an option for big tech.
Margin expansion from factory utilization and throughput. Scaling the Memphis facility allows AAON to spread fixed costs over much higher volumes, driving gross margins back toward 30%.
Market share gains in high-efficiency commercial heat pumps. Stricter DOE regulations favor AAON's superior technical designs, forcing building owners to switch away from cheaper, less efficient rivals.
Scaling costs and manufacturing inefficiencies persist at new sites. Rapidly hiring and training new staff for the Memphis ramp could lead to quality issues or higher-than-expected overhead costs.
Concentration in a few large hyperscale data center customers. If a single major tech giant shifts its cooling strategy or delays a build-out, AAON's $1.4 billion BASX backlog could shrink rapidly.
Competitive response from larger diversified industrials like Vertiv. Larger rivals could use their massive service networks to offer bundled "power and cooling" deals that AAON cannot match.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach (price-to-earnings applied to next year's earnings) to value the business. It fits AAON because the company is in a massive growth transition where historical earnings are less relevant than the "earning power" of its new, larger factory footprint. P/E is the most reliable way to value a consistently profitable industrial company while accounting for its accelerating growth in the data center market.
Next year's earnings per share (EPS) of $3.46 multiplied by a 32x multiple gives a per-share fair value of $111. A 32x multiple sits between mature heating and cooling peers like Trane (30x) and high-growth data center infrastructure peers like Vertiv (40x), which is justified by AAON's superior growth rate and $2.1 billion backlog (orders already on the books). Our calculation uses the $3.46 EPS estimate for FY2027 provided by the deterministic projection engine to ensure our valuation is anchored to the company's confirmed growth path.
An EV/Revenue (enterprise value compared to total sales) cross-check produces a fair value of $112, which is within 1% of our $111 answer. By applying a 4.0x multiple to the projected FY2027 revenue of $2.43 billion and subtracting the company's debt, we find a nearly identical result. This provides strong evidence that a $111 price is a fair reflection of the company's total value, as a 4.0x revenue multiple is consistent for industrial companies that are successfully pivoting into the high-growth AI infrastructure sector.
We're assuming that the BASX data center business effectively doubles its revenue over the next 18 months. Management recently raised its sales outlook for this segment from $715 million to $1.0 billion, and given the record-breaking backlog of $2.1 billion, there is high visibility that these orders will turn into actual sales as production capacity ramps up.
We're assuming profit margins recover to roughly 30% by late 2027. While margins are currently squeezed at 24% to 26% due to the costs of opening new facilities and training staff, AAON has a long history of high-end engineering that supports premium pricing, and these "ramp-up" costs are typically temporary during a massive growth phase.
We're assuming the legacy commercial HVAC business remains stable even if new construction slows down. AAON has successfully shifted its focus to the "replacement market" (replacing old units on existing buildings) during previous economic downturns, which provides a safety net if the broader building market remains soft through 2027.
The biggest risk is that the high costs of expanding factories and hiring new workers continue to eat into profits longer than investors expect. This "margin pressure" (lower profit per dollar of sales) would likely force the market to lower the stock's multiple (the price-to-earnings ratio) from 32x to 22x, knocking roughly $35 off the per-share fair value. Watch the "Gross Margin" figure in the next two earnings reports for any sign that it is staying below 26%.
Bear case ($75): Legacy commercial construction revenue drops more than 15% year-over-year, canceling out the gains from the data center segment; or Production delays in the Memphis facility prevent the company from converting its backlog into cash, keeping free cash flow negative through 2027.
Bull case ($138): Data center sales (BASX brand) exceed $1.2 billion in 2027 as AI demand forces customers to adopt more expensive custom liquid-cooling solutions; or Profit margins recover to historical 30% levels faster than expected as the company finishes its expensive factory expansion phase.
