**AAON Reports First Quarter 2026 Results with Record Sales and Backlog, Robust Earnings Growth, and Raises Full-Year Guidance**

**First Quarter 2026 Results**

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

• Delivered record sales and accelerated earnings growth on strong demand and expanding production throughput

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Net sales grew 54.3% to a record $496.9 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Operating margins reflected early benefits from improving utilization, with margin improvement expected to build as capacity absorption improves

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ GAAP diluted EPS increased 37.1% to $0.48 reflecting strong earnings growth on higher volume

• Total backlog increased 107.4% to a record $2.1 billion, driven by continued strength from the data center market<br>

**Raises 2026 Outlook**

• 2026 outlook now reflects revenue growth of 40%-45% and gross margins of approximately 27-28%, supported by record backlog, expanded capacity, and improving operational execution

TULSA, Okla., May 7, 2026 - 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 first quarter of 2026.

**First Quarter 2026 Results**

Net sales for the first quarter of 2026 increased 54.3% to $496.9 million, from $322.1 million in the first quarter of 2025. This growth was driven by strong demand across both the AAON and BASX brands, and accelerating production throughput made possible by investments made in capacity and operational execution. BASX-branded sales increased 72.4% to $228.6 million, reflecting continued strength in data center cooling demand, higher production volumes, and increased utilization of recently commissioned capacity. AAON-branded sales increased 41.6% to $268.4 million, supported by a strong backlog and accelerating production rates. Booking activity remained solid across both brands, supporting continued share gains and elevated backlog levels. BASX-branded products ended the quarter with backlog up 160.0%, while AAON-branded bookings demonstrated continued resilience in a softer market environment.

Gross profit margin in the quarter was 25.1%, compared to 26.8% in the prior-year period. The year-over-year decline reflected unabsorbed fixed costs associated with recent capacity investments, temporary outsourcing used to support accelerated growth, and transitory price and cost timing dynamics. These effects are intentional and temporary, and are expected to unwind as internal capacity scales and utilization improves.

Selling, general and administrative expenses as a percent of sales declined 220 basis points to 13.7%, demonstrating strong operating leverage and disciplined cost management.

Earnings per diluted share were $0.48, an increase of 37.1% from $0.35 in the first quarter of 2025.

------

"First-quarter results demonstrate strong earnings growth driven by higher volume, improved execution, and continued share gains," said President and CEO Matt Tobolski. "We delivered record sales, improved cash flow, and higher production throughput across our manufacturing network. Importantly, the additional volume we are taking on is carrying attractive incremental contribution, allowing earnings to grow while we intentionally sequence margin improvement during this phase of capacity ramp.

"Our backlog provides exceptional visibility, particularly across the BASX-brand, and positions us to drive continued growth as we move through the year. At the same time, increasing utilization across existing capacity is expected to support margin improvement over time as fixed costs are absorbed, equipment comes fully online, and productivity continues to improve.

"As we progress through 2026, our priorities are clear and unchanged. Drive throughput, convert backlog, and deliver disciplined margin progression over time. We have built the foundation, and we are now focused on converting that foundation into durable earnings power and long-term returns."

|  | $2129455 | $1828495 | $1026869 |

---

Total backlog increased 107.4% year-over-year to $2.13 billion, and increased 16.5% sequentially. The sequential growth was driven entirely by the BASX brand, with backlog increasing 24.4% from the prior quarter. Sustained data center demand and BASX's custom-engineered solutions continue to support share gains. As planned, AAON-branded products backlog declined sequentially 3.1%, reflecting a deliberate increase in production to address extended lead times, with manufacturing output exceeding order intake during the quarter. Order activity of AAON equipment remained solid, supporting continued share gains despite softer end-market conditions.

**2026 Outlook**

Dr. Tobolski concluded, "We are encouraged by the start of the year and the momentum we are seeing across the business. Backlog and demand remain exceptionally strong, providing the visibility and stability needed to maintain a sharp focus on execution, production ramp-up, and customer fulfillment. We are pleased with the benefits we are starting to see from operational investments, and we have meaningful opportunity ahead to further increase production volumes and enhance productivity, which support improved results over time.

"We now expect 2026 sales to grow 40%-45%, with gross margin of 27%-28%, reflecting intentional ramp decisions early in the year and improving margin as utilization and productivity increases through the year. We anticipate SG&A expenses as a percentage of sales will be 14%-15% and expect depreciation and amortization expenses of $95-$100 million."

| Gross profit | $64272 | $59168 | $40600 |
| Gross profit margin | 26.3% | 27.5% | 25.1% |

---

Net sales for the AAON Oklahoma segment totaled $244.0 million, an increase of 50.7% year-over-year, driven by a strong starting backlog and ongoing production enhancements that improved backlog conversion despite a challenging industry environment. First-quarter 2026 results also benefited from an easier year-over-year comparison, as the prior-year period was disrupted by the industry's refrigerant transition, contributing to regained market share.

Gross margin for the segment was 26.3%, compared to 25.1% in the first quarter of 2025. Overhead expenses associated with the new Memphis facility impacted segment margin by $9.8 million. Excluding these costs, segment margins were 29.6%. During the quarter, the segment was impacted by elevated outsourcing levels, price-cost timing dynamics, and tariff-related costs, all of which are temporary and do not change the long-term earnings power of the segment.

| Gross profit | $28302 | $21827 | $29858 |
| Gross profit margin | 24.1% | 21.3% | 31.8% |

---

Net sales for the AAON Coil Products segment totaled $117.6 million, up 25.1% compared to the same period last year. Growth was driven primarily by BASX-branded liquid cooling sales of $93.2 million, up 40.5% during the period, while AAON-branded sales declined 11.8% year-over-year.

AAON Coil Products gross margin was 24.1%, declining year-over-year from 31.8%, but increasing sequentially from 21.3%. The sequential margin expansion reflected improved operating leverage on higher throughput at the Longview facility, including a favorable mix of higher-margin BASX sales.

| Gross profit | $32391 | $28775 | $15906 |
| Gross profit margin | 23.9% | 27.1% | 24.0% |

---

Net sales for the BASX segment increased 104.5% to $135.4 million from $66.2 million in the prior-year period. The year-over-year growth reflected strong demand for data center equipment, supported by robust order intake and elevated backlog levels. Increased production from the Company's new Memphis facility played a key role by expanding capacity and driving higher sales volumes.

BASX segment gross margin was 23.9%, unchanged from the prior-year period. Margin stability reflected strong volume growth, offset by incremental resources and investments to support future growth and share gains. These incremental costs also contributed to the sequential margin contraction.

**Balance Sheet & Cash Flow**

As of March 31, 2026, the company had cash, cash equivalents and restricted cash of $1.1 million and a balance on its revolving credit facility of $425.2 million. Andy Cheung, CFO and Treasurer, commented, "During the first quarter, operating cash flow totaled $34.0 million, representing the highest level since the third quarter of 2024. This improvement reflected higher earnings and enhanced working capital efficiency. Capital expenditures totaled $52.9 million, primarily reflecting continued investments in incremental capacity to support future growth. As improvements in profitability and productivity continue, we expect these trends to support stronger cash flow and a healthier balance sheet over time."

**Conference Call** 

The company will host a conference call and webcast this morning at 9:00 a.m. EST to discuss the first quarter of 2026 results and outlook. The conference call will be accessible via dial-in for those who wish to participate in Q&A as well as a listen-only webcast. The dial-in is accessible at 1-888-880-3330.

**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.
