**AAON Reports Strong Third Quarter 2025 Results Driven by Operational Improvements and Share Gains**

**Q3 Highlights**

(All comparisons are year-over-year, unless otherwise noted)

• Operations improved sequentially, driven by continued demand, improved ERP efficiency and increased production throughput

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Net sales up 17.4% to $384.2 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ GAAP diluted EPS of $0.37 down year-over-year 41.3%, up sequentially 94.7%

• Robust bookings trends of both AAON- and BASX-branded equipment point to continuing market share gains

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Record backlog of $1.32 billion up year-over-year 103.8% and up sequentially 18.1%

TULSA, Okla., November 6, 2025 - AAON, INC. (NASDAQ-AAON), a leader in high-performing, energy-efficient HVAC solutions that bring long-term value to customers and owners, today announced its results for the third quarter of 2025.

The quarter demonstrated robust underlying demand across both AAON and BASX brands. Total backlog reached a record $1.32 billion, up 103.8% year-over-year and 18.1% sequentially, with particularly solid momentum in data center applications. National account bookings increased 96% in the quarter and 92% year-to-date, reflecting continued market share gains despite softness in the broader nonresidential construction market.

**Third Quarter 2025 Results**

Net sales for the third quarter of 2025 increased 17.4% to $384.2 million, from $327.3 million in the third quarter of 2024. BASX-branded sales rose 95.8% to $124.8 million, driven primarily by increased demand of liquid cooling equipment for data center applications. AAON-branded sales decreased year-over-year 1.5% to $259.5 million, but rose 28.1% sequentially, reflecting steady production momentum at the Tulsa, Oklahoma, facility. Bookings for both brands remained solid, led by the BASX brand, which saw a 119.5% increase in backlog. AAON-branded bookings were roughly flat with the prior-year period.

Gross profit margin in the quarter was 27.8%, down from 34.9% in the prior-year period but up sequentially from 26.6%. The year-over-year contraction primarily reflected operational inefficiencies associated with the Enterprise Resource Planning ("ERP") system implementation and unabsorbed fixed costs at the new Memphis facility. Sequential improvement in gross margin was driven by higher production volumes at the AAON Oklahoma and AAON Coil Products segments and continued progress in optimizing use of the new ERP system.

Earnings per diluted share were $0.37, down year-over-year 41.3%, but up sequentially by 94.7%.

"Our third quarter results demonstrate the enduring demand for our products and reflect continued share gains, margin improvement and steady progress toward our operational goals, with notable sequential improvement in several key areas," said AAON President and CEO Matt Tobolski. "Most notably, we achieved significant gains in production throughput at our Longview, Texas, facility, reflecting continued progress implementing our new ERP system. Production of AAON-branded equipment at the Longview facility improved each month during the quarter, reaching 90% of target in September and exceeding that level in October. Operational gains at both facilities contributed to an 28.1% increase in AAON-branded equipment sales from the prior quarter.

------

"We are also making tremendous progress with our BASX brand as we broaden our reach in the data center market and continue to deliver industry-leading air-side and liquid cooling solutions. Production of liquid cooling equipment has increased substantially since earlier in the year. We're optimizing operations in Redmond, Oregon, and continue to invest in expanding production at our new Memphis, Tennessee, facility to support the significant growth and margin expansion potential for our data center cooling products. We remain on track to add substantial production capacity by year-end, ensuring we can meet growing customer demand and continue driving operational excellence.

"As we enter the last quarter of the year, we remain confident in the progress we are making and the momentum we have built. Backlogs for both brands remain strong, bookings continue to trend positively, and we are making steady strides in expanding production capacity. In addition, we are achieving substantial gains in ERP system integration and have a clear path for continued operational excellence and growth as we further scale production and complete future ERP rollouts. Collectively, these initiatives are enhancing the strength of the Company, driving higher operational efficiency, and positioning us to capture additional growth."

**Segment Results**

**AAON Oklahoma**

|<br>***(in thousands)*** | **September 30, 2025** | **June 30, 2025** | **September 30, 2024** |
| Net sales | $238748 | $185120 | $228887 |
| Gross profit | $75229 | $50883 | $84119 |
| Gross profit margin | 31.5% | 27.5% | 36.8% |

---

Net sales for the AAON Oklahoma segment totaled $238.7 million, a 4.3% increase year-over-year, reflecting a larger starting backlog and enhanced production throughput that supported higher backlog conversion. With minimal external challenges during the quarter, the team was able to focus on hiring, training, and increasing production output.

Gross margin at the segment was 31.5%, down from 36.8% in the third quarter of 2024, but up 400 basis points from the prior quarter. The year-over-year decrease was primarily driven by incremental overhead expenses of $4.5 million related to our new plant in Memphis, as well as a temporary mismatch in timing between higher material costs associated with tariffs and the benefit from our 6% tariff surcharge, which has not yet been realized.

**AAON Coil Products**

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** | **Three Months Ended** |
|<br>***(in thousands)*** | **September 30, 2025** | **June 30, 2025** | **September 30, 2024** |
| Net sales | $70246 | $58465 | $35232 |
| Gross profit | $11332 | $12863 | $12421 |
| Gross profit margin | 16.1% | 22.0% | 35.3% |

---

Net sales for the AAON Coil Products segment totaled $70.2 million, up 99.4% compared to the same period last year. The year-over-year increase was fully driven by $46.5 million in BASX-branded liquid cooling product sales, a category that was not in production during the prior-year period. AAON-branded products declined $10.9 million due to disruptions related to the ERP system transition. However, these disruptions were much less compared to the prior quarter, reflecting improved utilization of the new ERP system and a 36.2% sequential increase in AAON-branded sales.

------

Gross margin at the segment was 16.1%, down year-over-year from 35.3% and sequentially from 22.0%. Despite the sequential improvement in throughput, gross margin declined sequentially, reflecting several discrete items that collectively impacted gross margin by approximately 1,050 basis points. We expect these challenges to be resolved as we continue making progress with our ERP implementation, and over time we expect this segment to deliver gross margin of around 30% based on the strength of pricing within backlog.

**BASX**

|:---|:---|:---|:---|

|<br>***(in thousands)*** | **September 30, 2025** | **June 30, 2025** | **September 30, 2024** |
| Net sales | $75244 | $67982 | $63133 |
| Gross profit | $20300 | $18983 | $17618 |
| Gross profit margin | 27.0% | 27.9% | 27.9% |

---

Net sales for the BASX segment increased 19.2% to $75.2 million, up from $63.1 million in the prior-year period. Stronger demand for data center equipment was the primary driver of the year-over-year increase, as the data center market continues to demonstrate exceptional strength. Initial production from our new Memphis facility played a key role in driving growth.

Gross margin at the segment was 27.0%, down from 27.9% in the prior-year period. The modest year-over-year contraction primarily reflects higher indirect warehouse personnel costs associated with operating the Redmond, Oregon, facility near full capacity. Optimization efforts at this facility remain a focus and are expected to accelerate as the Memphis facility continues to ramp up.

**Balance Sheet & Cash Flow**

As of September 30, 2025, the company had cash, cash equivalents and restricted cash of $2.3 million and a balance on its revolving credit facility of $360.1 million. Rebecca Thompson, AAON CFO and Treasurer, commented, "Overall, our financial position remains strong. We anticipate cash flow from operations will turn significantly positive in the fourth quarter as working capital becomes a source of cash, reflecting payments received on a large order that was recently delivered. This gives us flexibility to continue to focus on our investment in growth for the future with capital expenditure plans of $180.0 million in 2025."

Total backlog increased year-over-year 103.8% to $1,320.1 million, and 18.1% quarter-over-quarter. BASX-branded backlog drove the growth, increasing 119.5% from a year ago and 43.9% from the previous quarter. Our growing backlog and robust order activity demonstrate that we are capturing meaningful market share as customers prioritize high-performance, efficient, and reliable infrastructure. A meaningful part of the BASX-branded backlog is slated for production at the Memphis facility, which will support a steady ramp in production next year. AAON-branded equipment backlog increased 77.1% year-over-year but declined sequentially by 14.3%, reflecting the impressive increase in production output. Despite softness in the nonresidential construction market, bookings for the quarter remained strong and roughly flat compared to the prior-year period, indicating that we are continuing to gain meaningful market share.

**Use of Non-GAAP Financial Measures**

To supplement the company's consolidated financial statements presented in accordance with generally accepted accounting principles ("GAAP"), additional non-GAAP financial measures are provided and reconciled in the following tables. The company believes that these non-GAAP financial measures, when considered together with the GAAP financial measures, provide information that is useful to investors in understanding period-over-period operating results. The company believes that this non-GAAP financial measure enhances the ability of investors to analyze the company's business trends and operating performance as they are used by management to better understand operating performance. Since adjusted net income, adjusted net income per diluted share, EBITDA, adjusted EBITDA, and adjusted EBITDA margin are non-GAAP measures and are susceptible to varying calculations, adjusted net income, adjusted net income per diluted share, EBITDA, adjusted EBITDA, and adjusted EBITDA margin, as presented, may not be directly comparable with other similarly titled measures used by other companies.

**Non-GAAP Adjusted Net Income**

The company defines non-GAAP adjusted net income as net income adjusted for any infrequent events, such as litigation settlements, net of profit sharing and tax effect, in the periods presented.

The following table provides a reconciliation of net income (GAAP) to non-GAAP adjusted net income for the periods indicated:

**EBITDA**

EBITDA (as defined below) is presented herein and reconciled from the GAAP measure of net income because of its wide acceptance by the investment community as a financial indicator of a company's ability to internally fund operations. The company defines EBITDA as net income, plus (1) depreciation and amortization, (2) interest expense (income), net and (3) income tax expense. EBITDA is not a measure of net income or cash flows as determined by GAAP. EBITDA margin is defined as EBITDA as a percentage of net sales.

The company's EBITDA measure provides additional information which may be used to better understand the company's operations. EBITDA is one of several metrics that the company uses as a supplemental financial measurement in the evaluation of its business and should not be considered as an alternative to, or more meaningful than, net income, as an indicator of operating performance. Certain items excluded from EBITDA are significant components in understanding and assessing a company's financial performance. EBITDA, as used by the company, may not be comparable to similarly titled measures reported by other companies. The company believes that EBITDA is a widely followed measure of operating performance and is one of many metrics used by the company's management team and by other users of the company's consolidated financial statements.

Adjusted EBITDA is calculated as EBITDA adjusted by items in non-GAAP adjusted net income, above, except for taxes, as taxes are already excluded from EBITDA.
