## Customers

AAON sells primarily into non-residential HVAC channels and project-driven end markets, with demand tied to new construction, retrofits, and capacity expansions. A large portion of volume flows through an extensive network of independent representatives and channel partners that support specification, bidding, and service for commercial projects. BASX’s customer set is more concentrated and program-based, serving hyperscale data center operators and their ecosystem, where order timing can shift and cancellations/re-issuances occur. The company also serves cleanroom environments in biopharmaceutical, semiconductor, medical, and agricultural applications where filtration, humidity control, and reliability are critical. AAON discloses that a small number of customers can represent 10%+ of revenue in a given year, while the remainder is spread across thousands of transactions.

- **Commercial HVAC channel partners (independent reps/portfolio groups)** (primary) — Buy semi-custom rooftop units, air handlers, makeup air and related systems to specify and deliver HVAC solutions for non-residential buildings; value configurability, lead times, and lifecycle performance.
- **Hyperscale data center customers and ecosystem** (primary) — Buy BASX custom cooling and modular air handling solutions for high-density compute and AI workloads; prioritize reliability, scalability, and integration with facility designs.
- **Cleanroom and controlled-environment facilities** (secondary) — Buy ventilation/air handling solutions with advanced filtration, humidity/dehumidification, and controls for biopharmaceutical, semiconductor, medical, and agricultural environments.
- **Aftermarket parts and controls buyers** (emerging) — Purchase replacement parts and controls upgrades via retail locations and online to maintain uptime and extend the life of installed AAON equipment.

- Hyperscale data center operators needing high-performance cooling capacity
- Data center developers/operators (e.g., QTS, Applied Digital) for expansions
- Independent HVAC representatives specifying AAON equipment on projects
- Commercial/institutional building owners (schools, hospitals, offices)
- Cleanroom operators in biopharma and semiconductor needing filtration control
- Industrial and warehouse facilities prioritizing durable packaged HVAC

## Geography

AAON’s manufacturing footprint is U.S.-based, with major operations in Tulsa, Oklahoma; Memphis, Tennessee; Parkville, Missouri; Longview, Texas; and Redmond, Oregon. The company sells across all 50 U.S. states and into certain Canadian provinces, reflecting a North America-focused go-to-market model. Reported foreign sales are relatively small versus total sales (e.g., $11.3 million in Q1 2025), implying limited direct exposure to international demand cycles but some cross-border logistics and compliance needs. The distributed plant network supports different product lines (coils, commercial HVAC, and BASX custom solutions) and influences cost absorption and segment margins when volumes shift. Geographic reach matters operationally because project demand (especially data centers) can be regionally clustered and can create uneven capacity utilization across plants.

- Sales coverage across all 50 U.S. states supports national rep network
- Canada sales to certain provinces adds incremental North America demand
- Tulsa, Oklahoma HQ with NAIC R&D lab supports product testing and design
- Longview, Texas coil manufacturing also produces BASX-branded products
- Redmond, Oregon is the core BASX custom manufacturing location
- Memphis, Tennessee plant supports BASX builds and affects segment cost mix

## Strategy

AAON’s strategy centers on mass semi-customization—using flexible, computer-aided manufacturing to deliver configurable equipment that fits project requirements while retaining scale economics. The company is investing in capacity and capabilities to support growth in adjacent end markets, particularly data centers and cleanroom applications, while maintaining its commercial HVAC base. Operationally, management is modernizing systems and processes, including an ERP rollout at the Longview, Texas facility, to improve planning, execution, and scalability (despite near-term disruption). AAON also emphasizes engineering differentiation through its Tulsa-based innovation and testing infrastructure (NAIC) to validate performance under extreme conditions and support premium positioning. Capital expenditures remain a key lever to expand throughput and support new product and program requirements.

- **Stabilize ERP-driven operations at Longview (AAON Coil Products)** (short-term) — Process changes disrupted coil output and impacted both coil and upstream HVAC production; normalization supports margins and delivery performance.
- **Invest in capacity and organizational build-out for growth** (medium-term) — Higher capex and added headcount aim to support future demand in data centers, cleanrooms, and broader commercial HVAC.
- **Deepen presence in hyperscale data center cooling programs** (medium-term) — Data center demand can be large and program-based, offering growth but requiring execution, customization, and schedule flexibility.

- Scale mass semi-customization to win specified, project-driven HVAC demand
- Expand data center cooling and modular solutions via BASX programs
- Grow cleanroom ventilation presence in biopharma and semiconductor markets
- Invest in manufacturing capacity and automation through elevated capex
- Stabilize and optimize ERP-enabled planning after Longview go-live

## Risks

AAON’s results are exposed to construction and capex cycles in commercial buildings and data centers; weaker macro conditions can reduce project starts and retrofit activity. Customer concentration is a recurring risk, as a small number of customers can represent 10%+ of revenue and accounts receivable, increasing sensitivity to program timing and credit dynamics. The BASX data center business carries higher backlog volatility, with timing shifts, cancellations, and re-issuances that can create production inefficiencies and margin variability. Operational execution risks include ERP and new facility ramp impacts that can disrupt throughput and overhead absorption, as seen in recent periods. Like other HVAC manufacturers, AAON is also exposed to raw material price volatility (e.g., copper, steel, aluminum), supply chain disruptions, and cybersecurity threats to manufacturing and business systems.

- **Customer concentration in revenue and accounts receivable** [high] — A small number of customers have represented 10%+ of revenue and AR, making results sensitive to their purchasing patterns and credit exposure.
- **Data center order timing shifts, cancellations, and re-issuances** [high] — Management notes higher cancellation/timing risk in data center backlog versus historically firm commercial HVAC orders, which can disrupt production planning.
- **Cybersecurity threats to systems and operations** [medium] — The company integrates cybersecurity into enterprise risk management and uses third parties for testing/forensics, indicating ongoing threat exposure.
- **Public health pandemic disruption** [medium] — Pandemics can impair employees, suppliers, and partners, disrupting operations and supply chains and affecting raw material pricing.

- Customer concentration (10%+ revenue/AR customers) increases volatility
- Data center backlog timing shifts and cancellations affect BASX utilization
- ERP implementation disruptions can reduce output and pressure margins
- New plant ramp/overhead absorption can distort segment profitability
- Raw material price swings (copper, steel, aluminum) pressure pricing/margins
- Construction and macro slowdowns reduce commercial HVAC project demand
- Cybersecurity incidents could disrupt operations and sensitive data

## Accounting

AAON’s financial statements rely on management estimates and judgments that can materially affect reported results, particularly in areas such as impairment testing and contingencies. Goodwill and indefinite-lived intangibles (e.g., trademarks/trade names) are tested at least annually, and outcomes depend on assumptions about industry trends, forecast cash flows, and profitability; changes in assumptions can trigger impairment charges. Share-based compensation is measurement-sensitive because option and PSU fair values depend on valuation models (Black-Scholes and Monte Carlo) and inputs such as volatility and expected term, affecting operating expenses. The company also discloses raw material purchase commitments and records loss contingencies for legal matters when probable and estimable, which can shift period-to-period based on developments. Investors should also watch for operational system changes (e.g., ERP implementation) that can affect inventory costing, overhead absorption, and margin comparability across quarters.

- **Goodwill and indefinite-lived intangible asset impairment** — Can create step-changes in operating income via impairment charges
- **Share-based compensation valuation (options, PSUs, key employee awards)** — Affects SG&A and comparability across periods
- **Loss contingencies and legal proceedings** — Can introduce discrete charges and cash outflows

- Goodwill/intangible impairment tests depend on cash flow assumptions
- Share-based comp uses Black-Scholes and Monte Carlo model inputs
- Loss contingencies require judgment on probability and estimable losses
- Purchase commitments disclosure informs near-term input cost exposure
- ERP/process changes can affect inventory costing and overhead absorption
