TULSA, Okla., March 2, 2026 /PRNewswire/ -- 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 fourth quarter and full year 2025.

Full Year 2025 Results

"2025 represented a year of record growth for AAON, driven by strong bookings and sales reflecting expanding market share and growing demand for our products and custom solutions," said AAON President and CEO Matt Tobolski. "During the year, we executed on targeted investments to support long-term growth and profitability. These actions included strengthening our leadership team, enhancing supply chain management capabilities, and expanding manufacturing capacity. These investments have increased production throughput and expanded our ability to serve customers at scale, although lead times have remained extended as a result of strong order activity and recovery from prior production challenges.

"Our manufacturing footprint increased approximately 25%, and our production capacity for BASX-branded data center equipment more than doubled following the renovation and commissioning of our new 787,000-square-foot Memphis, Tennessee facility. Together, these investments have significantly strengthened the Company's operating foundation and position us well for continued growth and margin improvement in 2026 and beyond.

"The BASX brand more than doubled revenue and ended the year with backlog up 141.3%, reflecting strong adoption of our customized air-side and liquid cooling solutions in the data center market. Demand for AAON-branded equipment also remained strong, and production increased steadily throughout the year, with additional ramping planned. We made substantial progress stabilizing and advancing the implementation of our new Enterprise Resource Planning ("ERP") system. While the ERP rollout initially impacted production at our Longview, TX facility, operating performance improved consistently over time, reinforcing our confidence in execution as we focus on continued operational improvement and meeting customer commitments."

Fourth Quarter 2025 Results

Net sales for the fourth quarter of 2025 increased 42.5% to $424.2 million, from $297.7 million in the fourth quarter of 2024. BASX-branded sales increased 138.8% to $181.4 million, reflecting strong demand for both air-side and liquid cooling equipment for data center applications. AAON-branded sales increased 9.5% to $242.8 million, supported by a strong backlog and favorable comparison to the prior-year period, which was adversely impacted by the industry's refrigerant transition. Booking activity remained solid across both brands, led by the BASX brand, which ended the quarter with backlog up 141.3%, while AAON-branded bookings increased approximately 20% compared to the prior-year period.

Gross profit margin in the quarter was 25.9%, compared to 26.1% in the prior-year period. The modest year‑over‑year decline primarily reflected unabsorbed fixed‑cost investments at the Company's new Memphis facility as production capacity was brought online to support a significant ramp of BASX‑branded data center equipment, positioning the business for improved operating leverage as volume scales.

Earnings per diluted share were $0.39, an increase of 30.0% year-over-year.

Dr. Tobolski added, "During the quarter, we made meaningful progress expanding production capacity and further advanced our operational readiness for sustained long-term growth. Production at our new Memphis facility is ramping rapidly, while our Longview, Texas facility continues to scale, increasing our ability to support accelerating demand for our data center equipment. BASX-branded equipment sales increased 138.8% year-over-year in the fourth quarter, and backlog increased 141.3%, providing strong visibility as we enter 2026.

"AAON‑branded equipment sales increased 9.5% year‑over‑year, representing our strongest quarterly growth since the second quarter of 2024. Despite typical seasonal headwinds, we ended the year with backlog up 60.8%, underscoring the strength and durability of underlying demand. We have a clear and disciplined operational plan in place to continue ramping production in 2026, positioning the Company to deliver solid growth and margin expansion.

"Fourth‑quarter margins reflected mixed operating dynamics across our facilities. While production volumes in Tulsa were below plan, Memphis reached profitability earlier than expected, validating our investment strategy. Fixed‑cost under‑absorption continues to pressure consolidated margins in the near term; however, these impacts are largely transitory and directly tied to capacity ramp-up that is already underway, positioning the Company for improved operating leverage as volumes scale. With capacity in place and execution continuing to improve, we remain confident in our path toward meaningful margin expansion throughout 2026."

Backlog

Total backlog increased 110.9% year-over-year to $1.83 billion, and increased 38.5% sequentially. Growth was driven primarily by the BASX-brand, with backlog increasing 141.3% from the prior year and 45.2% from the prior quarter, while AAON-branded equipment backlog increased 60.8% year-over-year. The Company's growing backlog and robust order activity demonstrate meaningful market share capture as customers prioritize high-performance, energy-efficient, and reliable infrastructure solutions. A significant portion of the BASX-branded backlog is slated for production at the Memphis facility, which will support a steady ramp in production in 2026.

2026 Outlook

Dr. Tobolski concluded, "As we enter early 2026, we are positioned to build on the investments made throughout 2025 in our people, products, manufacturing capabilities, and working capital. While these initiatives carried upfront costs and impacted near-term results, they have meaningfully strengthened AAON's operating foundation and positioned the Company to meet the growing demand in the data center market.

"Our ERP upgrade presented short-term challenges, which are now largely behind us, and is expected to deliver lasting benefits through improved production throughput, operating efficiency, and margin expansion. We begin 2026 with record backlog, allowing us to remain sharply focused on execution and customer delivery. To support a disciplined ramp in production throughput and accelerate margin improvement, we have moderated the pace of near-term ERP rollouts, enhancing returns on our recent investments while ensuring the Company remains well positioned for future IT system upgrade.

"With these actions in place, and with operational execution continuing to improve, we expect 2026 sales to grow 18%-20%, with gross margin of 29%-31%. We also anticipate SG&A expenses as a percentage of sales will be approximately 16% and expect depreciation and amortization expenses of $95-$100 million."

Segment Results

AAON Oklahoma

Net sales for the AAON Oklahoma segment totaled $215.5 million, an increase of 11.1% year-over-year, driven by a strong starting backlog and ongoing production enhancements that improved backlog conversion despite a challenging industry environment. Results in the fourth quarter of 2025 also benefited from a favorable comparison to the prior-year period, which saw disruption due to the industry's refrigerant transition in the prior-year period.

Gross margin for the segment was 27.5%, compared to 30.7% in the fourth quarter of 2024. The year-over-year decrease was fully attributable to $6.4 million of incremental overhead associated with the Company's new Memphis facility, reflecting investments made to support future production growth and operating leverage.

AAON Coil Products

Net sales for the AAON Coil Products segment totaled $102.6 million, up 93.6% compared to the same period last year. Growth was driven primarily by $75.3 million in BASX-branded liquid cooling sales, which increased 198.7% during the period. AAON-branded sales declined 1.8% year-over-year, but increased 15.2% sequentially, highlighting strengthening production momentum.

AAON Coil Products gross margin was 21.3%, increasing year-over-year from 16.1% and sequentially from 11.0%. The year‑over‑year margin expansion reflected improved operating leverage on higher throughput at the Longview facility, along with a favorable mix of higher-margin BASX sales.  This was partially offset by a full five‑day plant shutdown at Longview at year‑end to conduct a wall‑to‑wall inventory count.

BASX

Net sales for the BASX segment increased 109.1% to $106.1 million, compared to $50.7 million in the prior-year period. The year-over-year increase was driven by continued  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 in expanding capacity and driving higher sales.

BASX segment gross margin was 27.1%, compared to 18.8% in the prior-year period. The year‑over‑year improvement reflected a favorable comparison and accelerating production at the Memphis facility.

Balance Sheet & Cash Flow

As of December 31, 2025, the company had cash, cash equivalents and restricted cash of $1.2 million and a balance on its revolving credit facility of $398.3 million. Rebecca Thompson, AAON CFO and Treasurer, commented, "In 2025, we made substantial capacity and working‑capital investments to support our expanding backlog and ongoing market share gains.  As returns on these investments begin to materialize, we expect operating cash flow to improve significantly in 2026, supported by higher earnings and improved working‑capital efficiency. This gives us flexibility to continue to focus on our investment in growth for the future with capital expenditure plans of $190.0 million in 2026."

The reconciliation between consolidated gross profit to consolidated income from operations is as follows:

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.

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

Non-GAAP Adjusted Selling, General and Administrative Expenses

The following table provides a reconciliation of selling, general and administrative expenses (GAAP) to adjusted selling, general and administrative expenses (non-GAAP) for the periods indicated:
