Forward -looking statements are provided to allow potential investors the opportunity of management's beliefs and opinions in respect of the future so that they may use such beliefs and opinions as one factor in evaluating an investment. Some of the forward-looking statements may be identified by words such as "may", "plan", "foresee", "will", "should", "could", "anticipate," "believe," "expect," "intend," "potential," "continue," an d similar expressions.

The Company's forward-looking statements involve significant risks and uncertainties (some of which are beyond the Company's con trol) and assumptions that could cause actual future results to differ materially from the Company's historical experience and its present expectations or projections. Important factors that could cause results to differ materially from those in the forward-looking statements include (1) the timing and extent of changes in raw materials and component prices, (2) the effects of fluctuations in the commercial/industrial new construction market, (3) the timing and extent of changes in interest rates, as well as other competitive factors during the year, and (4) general economic, market or business conditions. For additional information and a discussion of such risks and uncertainties, which could cause the Company's actual results to differ from its projected results, please see its filings with the SEC, including its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K.

When forward- looking non-GAAP measures are provided, the Company does not provide quantitative reconciliations of forward-looking non-GAAP measures to the most directly comparable GAAP measures, because it cannot, without unreasonable effort, predict the timing and amounts of certain items taken into account in the computations of each of these measures. 2

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

![](aaoninvestorjune2025022.jpg)

…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
