Expanding and diversifying solutions This offering would be more custom than most standard offerings in the market, but more cost effective than a fully custom solution BASX is creating a new semi- custom, configurable product offering, similar to AAON 16

17 BASX’s future is bright Growing TAM Solutions-based, as opposed to product-based Custom engineering and manufacturing Leading innovation in both air-side and liquid cooling Premium customer service Strong backlog supported by expanding capacity

What does the AAON brand represent? • Most superior rooftop and split systems on the market • Industry leading innovation • Premium quality • Advanced technology and performance Multiple drivers of growth • Lowest total cost of ownership • Not just upfront cost thinking • Customer exploration center as proof of concept Leading value proposition for customers • Innovation and engineering • Semi-custom engineering & manufacturing • Built for application • Performance and energy efficiency AAON’s differentiators 18

Favorable secular market trends 19 Regulation Economics Decarbonization/ electrification Focus on energy efficiency and electrification has driven a replacement cycle Stricter regulation, such as lower GWP refrigerants, has been a driver of our growth Customers’ attractive total cost of ownership of our products have supported demand Multiple drivers to our target of MSD growth

Capitalizing on innovative heat pumps and national account opportunities 20 These strategies are mutually exclusive but complement each other to drive growth Existing market SAM TAM Recently, AAON established an internal national account sales team Targeting national accounts and their multi-year replacement programs from a centralized standpoint expands our SAM Leveraging heat pump capabilities gives AAON an edge Multi-hundred million dollar pipeline established

The refrigerant transition was disruptive in 2024… 21 Unprecedented regulation by the EPA was disruptive in many ways Transition to a new mildly flammable refrigerant (R-454B) forced an update to building codes, the first time in history this happened during a refrigerant change Slow adoption of the new refrigerant equipment in late 2024 and supply chain issues in early 2025, caused a temporary slowdown in orders and production

…But it was temporary, and AAON’s competitiveness has never been stronger 22 We were always confident this was going to be a temporary impact AAON’s cost of manufacturing the new refrigerant equipment is unchanged, whereas most competition has indicated increases to costs This has led to AAON being more competitive with price and our value proposition Potential result: accelerated share gains and margin expansion

Our premium offering has never been more attractive ¹ Price premium reflects AAON's price relative to the closest alternative in the market. 23 15-20% ~10% 5 Years ago Today Future The price premium to peers¹ has narrowed Our unique product offering, unmatched by competitors, proves to be of higher quality relative to market alternatives, justifying a price premium The value proposition has never been more attractive Share gains are accelerating as the price premium narrows <10%

40 Proving and showcasing AAON’s superiority The Gary D. Fields Exploration Center is the only showroom in the world where customers can see all the major brands of rooftop equipment side-by-side, with our products next to the alternatives It doesn’t take an engineer to quickly understand the premium quality This showroom along with new investments in marketing campaigns will lead to market share gains

Offering a solutions- based sales channel model 41 Building owners prefer this approach more than contracting with multiple sub-contractors Sales reps use AAON equipment to customize the ideal solution This solutions-based sales channel is superior to most factory products-based sales channels that we compete against AAON sells through an independently owned sales channel, with one representative firm in every region of North America Reps utilize a line card of 20-30 complimentary OEMs that help provide an overall solution to the end customer

Building strength in our go-to-market strategy Focus on parts and service AAON selling parts and supporting our sales channel in building a world class services operation is key to our solutions-based offering Leveraging the marketing function set up in 2022 Marketing budget up 10x since creation, strengthening market penetration by increasing brand recognition AAON’s go-to-market strategy is significantly more advanced than in the past, and key to contributing to the company’s market share gains and 12.5%-plus sales growth target Providing resources to the sales channel Customer Exploration Center Support services Training (new academy) Mobile experience Investing in sales Account management National Account director 42

Total addressable market and share gain opportunity¹ Nonresidential HVAC market 6% market share and growing $875M⁴ $14.5B² The addressable market of AAON’s commercial HVAC products, including rooftop units, air handlers and condensing units, is ~16x the size of our rooftop sales Positioned to take share as demand trends shift to meet energy efficiency and decarbonization requirements mid-single digits 3-year sales target 43 9% rooftop market share³ 1 All data on this slide is based on 2024. 2 Sources: Grand View Research, Next Move Strategy Consulting, SNS Insider Report 3 In 2024, the size of the rooftop unit market was $8.5B, compared to AAON's rooftop unit sales of $768M. 4 Sales only include equipment sales, and exclude parts, freight and other items.

Favorable secular trends 44 Decarbonization Energy efficiency Government regulations Total cost of ownership focus Our customized, highly automated platform allows us to adapt to these secular trends much more efficiently These secular trends are driving up the cost of manufacturing across the industry much more than what we are experiencing

45 Continuously becoming more competitive As the price premium narrows, we expand margins and increase our market share Prior to 2020, AAON’s average price premium relative to the alternative market solution was 15%-20% In the last few years, the company was able to bring that premium down to ~10% In 2025, we are narrowing the price premium further, driving share gains <10% No competitor can truly match AAON's premium product offering , justifying the price premium. Price premium reflects AAON's price relative to the closest alternative in the market.

Operationally, we’ve never been stronger Productivity gains and scaling the operations efficiently 30.5% 2020 35.2% 2024 Continuously finding ways to increase productivity and throughput AAON Oklahoma gross margin transformed At the Tulsa facility, we could increase production volumes by ~40% with minimal additional fixed costs 46

2023 AAON’s Alpha Class were the only heat pumps operable below 30OF, and were operable all the way down to 0OF 2025 Introducing Alpha Class with operability down to -20OF, meeting the Department of Energy’s challenge two years ahead of requirement 2024 AAON's total rooftop sales were down 5% The Alpha Class category was up 39% Continuing to innovate with Alpha Class and heat pumps ¹ All data is based on 2024. 48 Alpha Class is a product category of the AAON brand that includes commercial HVAC equipment fueled by a fully electric heat pumps There is a large pipeline of customers interested in decarbonizing and electrifying their HVAC systems ~15% of rooftop sales¹ 10% of total company sales¹

National account opportunity 49 Landing just one or two national accounts per year could be meaningful and incremental to traditional growth Many are interested in electrifying their HVAC systems, with Alpha Class giving us an advantage A substantial percentage of this pipeline is focused on multi-year programs In the last 20 years National accounts were not a big focus In Early 2024 In early 2024 Began to target national account opportunities Last 18 months Built a pipeline of opportunity with annualized sales of several hundred million dollars

Impacts from the recent refrigerant regulation 50 Planning production and management inventory was incredibly challenging On a positive note, our semi-custom platform was able to handle the transition better than most of the competition Our YTD book of orders implies that we are already back to taking market share The weak Q4 and Q1 we experienced was temporary

Our bookings are recovering from the refrigerant transition 51 391.8 364.1 364.9 400.5 417.9 355.5 307.1 276.6 278.6 255.5 239.1 327.3 403.9 1Q22 2Q22 3Q22 4Q22 1Q23 2Q23 3Q23 4Q23 1Q24 2Q24 3Q24 4Q24 1Q25 AAON backlog ($M)
