Form Type
10-Q
AAON, Inc. delivered strong first‑quarter growth, with net sales rising 54.3% to $496.9 million, driven largely by BASX-branded data center and cleanroom products. Net income increased to $39.8 million from $29.3 million, and diluted earnings per share improved to $0.48 from $0.35.
Gross margin was 25.1%, slightly below 26.8% a year ago as mix and ramp-up costs offset scale benefits, but operating margin edged up to 11.5%. Backlog more than doubled to $2.13 billion, led by BASX data center liquid cooling orders, supporting future revenue visibility.
The company generated $34.0 million of operating cash flow, funded $45.1 million of capital expenditures, and ended the quarter with a leverage ratio of 1.71 and $173.5 million of revolver availability. AAON also expanded tax-advantaged financing through multiple New Markets Tax Credit projects.
Positive
- Rapid growth and strong earnings: Q1 2026 net sales grew 54.3% to $496.9 million, net income rose to $39.8 million, and diluted EPS increased to $0.48, reflecting robust demand and improved operating leverage.
Negative
- None.
Insights
AAON posts rapid growth, record backlog, and solid liquidity.
AAON grew Q1 2026 net sales 54.3% to $496.9 million, powered by BASX-branded data center and cleanroom offerings. Net income rose to $39.8 million and diluted EPS to $0.48, while operating margin improved to 11.5%, showing good operating leverage despite slightly lower gross margin.
Backlog reached $2.13 billion, up 107.4% year over year, with BASX-branded backlog rising 160.0%. This indicates strong demand, particularly in data center liquid cooling, though realization will depend on project execution and customer schedules across AAON Oklahoma, AAON Coil Products, and BASX segments.
Leverage increased with Revolver borrowings of $425.2 million and a leverage ratio of 1.71, but available revolver capacity of $173.5 million and Q1 operating cash flow of $34.0 million support ongoing investments. New Markets Tax Credit financings, including a $50.5 million 2026 allocation, provide low-interest funding for capacity expansion.

New Markets Tax Credit financial
"under a qualified New Markets Tax Credit (“2026 NMTC”) program pursuant to Section 45D"
A new markets tax credit is a federal incentive that gives investors a dollar-for-dollar reduction in their tax bill in exchange for providing capital to businesses and projects in low-income communities. Think of it like a multi-year rebate that improves an investment’s after-tax return and makes riskier community development projects more financially attractive, so investors can both earn returns and support local economic growth.
variable interest entities financial
"we have the power to direct the activities of eight variable interest entities (“VIEs”)"
A variable interest entity (VIE) is a business that a company controls through contracts or special arrangements instead of owning a majority of its shares, like steering a puppet without holding its ticket. Investors care because these arrangements can hide who really bears the financial risks and rewards, affect how assets and liabilities appear on financial statements, and create extra legal or enforcement uncertainty that can change the value and risk of an investment.
secured overnight financing rate financial
"loans under the Revolver bear interest at the daily compounded secured overnight financing rate (“SOFR”)"
A secured overnight financing rate (SOFR) is a daily benchmark interest rate that reflects the cost of borrowing cash overnight using U.S. Treasury securities as collateral. Think of it as the market price to “rent” cash for a day with a very safe pledge, similar to paying a short-term rental fee for money backed by government bonds. Investors track SOFR because it underpins pricing for loans, bonds and derivatives, so movements change borrowing costs, interest income and the valuation of interest-rate–linked positions.
total shareholder return financial
"PSUs vest based on the level of achievement with respect to the Company's total shareholder return (“TSR”)"
Total shareholder return is the overall gain an investor gets from owning a stock, combining changes in the share price plus any cash payouts like dividends, and assuming those payouts are reinvested in more shares. Investors use it like a single score that shows the true return on their investment—similar to checking both the growth of a savings account and the interest earned—to compare how well different companies or investments perform over time.
bonus depreciation financial
"100% Bonus Depreciation: Effective for qualified property acquired after January 19, 2025"
A tax rule that lets a company write off a large portion of the cost of qualifying property or equipment immediately instead of spreading the expense over many years. Like taking a big one-time coupon when you buy a machine, it reduces taxable income and current cash taxes, which can boost short-term cash flow and alter reported profits. Investors watch it because it affects earnings, cash generation and how comparable one company’s results are to another’s.

AAON, Inc. and Subsidiaries
Notes to Consolidated Financial Statements
March 31, 2026
(Unaudited)
1. General
Basis of Presentation
AAON, Inc. is a Nevada corporation which was incorporated on August 18, 1987. Our operating subsidiaries include AAON, Inc. (“AAON Oklahoma”), an Oklahoma corporation, AAON Coil Products, Inc. (“AAON Coil Products”), a Texas corporation, and BASX, Inc. (“BASX”) an Oregon corporation (collectively, the “Company”). The accompanying unaudited consolidated financial statements of AAON, Inc. and our operating subsidiaries, all of which are wholly-owned, have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (“SEC”).
Our financial statements consolidate all of our affiliated entities in which we have a controlling financial interest. Because we hold certain rights that give us the power to direct the activities of eight variable interest entities (“VIEs”) (Note 18) that most significantly impact the VIEs economic performance, combined with a variable interest that gives us the right to receive potentially significant benefits or the obligation to absorb potentially significant losses, we have a controlling financial interest in those VIEs.
These financial statements have not been audited by the Company's independent registered public accounting firm, except that the consolidated balance sheet at December 31, 2025, is derived from audited consolidated financial statements. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The financial statements reflect all adjustments (all of which are of a normal recurring nature) which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. Interim results are not necessarily indicative of the results that may be expected for a full year. Certain disclosures have been condensed in or omitted from these consolidated financial statements. The accompanying unaudited financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. All intercompany balances and transactions have been eliminated in consolidation.
We are engaged in the engineering, manufacturing, marketing, and sale of premium air conditioning and heating equipment consisting of standard, semi-custom, and custom rooftop units, data centers cooling solutions, cleanroom systems, packaged outdoor mechanical rooms, air handling units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps, coils, and controls.
5
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because these estimates and assumptions require significant judgment, actual results could differ from those estimates and could have a significant impact on our results of operations, financial position, and cash flows. We reevaluate our estimates and assumptions as needed, but at a minimum on a quarterly basis. The most significant estimates include, but are not limited to, inventory valuation, inventory reserves, warranty accrual, income taxes, useful lives of property, plant, and equipment, estimated future use of leased property, share-based compensation, revenue percentage of completion and estimated costs to complete. Actual results could differ materially from those estimates.
Accounting Policies
A comprehensive discussion of our critical accounting policies and management estimates is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2025.
Fair Value Measurements
The carrying amounts of cash and cash equivalents, receivables, accounts payable, and accrued liabilities approximate fair value because of the short-term maturity of the items. The carrying amount of the Company’s debt, and other payables, approximates their fair values either due to their short-term nature, the variable rates associated with the debt or based on current rates offered to the Company for debt with similar characteristics.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. Fair value is based upon assumptions that market participants would use when pricing an asset or liability. We use the following fair value hierarchy, which prioritizes valuation technique inputs used to measure fair value into three broad levels:
•Level 1: Quoted prices in active markets for identical assets and liabilities that we have the ability to access at the measurement date.
•Level 2: Inputs (other than quoted prices included within Level 1) that are either directly or indirectly observable for the asset or liability, including (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities in inactive markets, (iii) inputs other than quoted prices that are observable for the asset or liability, and (iv) inputs that are derived from observable market data by correlation or other means.
•Level 3: Unobservable inputs for the asset or liability including situations where there is little, if any, market activity for the asset or liability. Items categorized in Level 3 include the estimated fair values of intangible assets, contingent consideration, and goodwill acquired in a business combination.
The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to a fair value measurement requires judgment, considering factors specific to the asset or liability.
Software Development Costs
We capitalize costs incurred to purchase or develop software for internal use. Internal-use software development costs are capitalized during the application development stage. These capitalized costs are reflected in intangible assets, net and goodwill on the consolidated balance sheets and are amortized over the estimated useful life of the software. The useful life of our internal-use software development costs is generally one to ten years .
Definite-Lived Intangible Assets
Our definite-lived intangible assets include customer relationships, internal-use software and other intellectual property acquired in business combinations or asset acquisition. We amortize our definite-lived intangible assets on
6
a straight-line basis over the estimated useful lives of the assets. We evaluate the carrying value of our amortizable intangible assets for potential impairment when events and circumstances warrant such a review.
Amortization is computed using the straight-line method over the following estimated useful lives:
| Intellectual property | |||||
| Customer relationships | |||||
Goodwill and Indefinite-Lived Intangible Assets
Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net of liabilities assumed. Goodwill at March 31, 2026, is expected to be tax deductible in future periods. Indefinite-lived intangible assets consist of trademarks and trade names. Goodwill and indefinite-lived intangible assets are not amortized but instead are evaluated for impairment at least annually. We perform our annual assessment of impairment during the fourth quarter of our fiscal year, and more frequently if circumstances warrant.
Recent Accounting Pronouncements
Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). We consider the applicability and impact of all ASUs. ASUs not listed or included within the Company's Annual Report on Form 10-K for the year ended December 31, 2025, were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto.

Aftermarket part sales (included in the AAON Product sales above) were $17.0 million and $15.2 million for the three months ended March 31, 2026 and 2025, respectively.
The Company recognizes revenue, presented net of sales tax, when it satisfies the performance obligation in its contracts. For certain manufactured equipment contracts and parts sales, the primary performance obligation in such a contract is delivery of the requested manufactured equipment. We satisfy the performance obligation when the control is passed to the customer, generally at time of shipment. Final sales prices are fixed based on purchase orders. Sales allowances and customer incentives are treated as reductions to sales and are provided for based on historical experiences and current estimates.
Due to the highly customized nature of many of the Company’s products and each product not having an alternative use to the Company without significant costs to the Company, the Company recognizes revenue over time as progress is made toward satisfying the performance obligations of each contract. The Company has formal cancellation policies and generally does not accept returns on these units. As a result, many of the Company’s products do not have an alternative use and have an enforceable right to payment, including a reasonable profit margin, and therefore, for these products, we recognize revenue over the time it takes to produce the unit.
Contract costs include direct materials, direct labor, installation, freight and delivery, commissions and royalties. Other costs not related to contract performance, such as indirect labor and materials, small tools and supplies, operating expenses, field rework and back charges are charged to expense as incurred. Provisions for estimated losses on contracts in progress are made in the period in which such losses are determined. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are estimated and recognized by the Company throughout the life of the contract. The aggregate of costs incurred, and income recognized on uncompleted contracts in excess of billings is shown as a contract asset within our consolidated balance sheets, and the aggregate of billings on uncompleted contracts in excess of related costs incurred and income recognized is shown as a contract liability within our consolidated balance sheets.
Historically, sales of our AAON products are moderately seasonal with the peak period being May-October of each year due to timing of construction projects being directly related to warmer weather.
8
Product Warranties
A provision is made for the estimated cost of maintaining product warranties to customers at the time the product is sold based upon historical claims experience by product line. The Company records a liability and an expense for estimated future warranty claims based upon historical experience and management’s estimate of the level of future claims. Changes in the estimated amounts recognized in prior years are recorded as an adjustment to the liability and expense in the current year.
The Company also sells extended warranties on parts for various lengths of time ranging from six months to 10 years. Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately priced warranty period.
Representatives and Third-Party Products
We are responsible for billings and collections resulting from all sales transactions, including those initiated by our independent manufacturer representatives (“Representatives”). Representatives are national companies that are in the business of providing heating, ventilation, and air conditioning (“HVAC”) units and other related products and services to customers. The end user customer orders a bundled group of products and services from the Representative and expects the Representative to fulfill the order. These other related products and services may include controls purchased from another manufacturer to operate the unit, start-up services, and curbs for supporting the unit (“Third Party Products”). All are associated with the purchase of an HVAC unit but may be provided by the Representative or another third party. Only after the specifications are agreed to by the Representative and the customer, and the decision is made to use an AAON HVAC unit, will we receive notice of the order. We establish the amount we must receive for our HVAC unit (“minimum sales price”), but do not control the total order price that is negotiated by the Representative with the end user customer. The Representatives submit the total order price to us for invoicing and collection. The total order price includes our minimum sales price and an additional amount which may include both the Representatives’ fee and amounts due for additional products and services required by the customer. The Company is considered the principal for the equipment we design and manufacture and records that revenue gross. The Company has no control over the Third Party Products to the end customer and the Company is under no obligation related to the Third-Party Products. Amounts related to Third-Party Products are not recognized as revenue but are recorded as a liability and are included in accrued liabilities on the consolidated balance sheets.
The Representatives’ fee and Third-Party Products amounts (“Due to Representatives”) are paid only after all amounts associated with the order are collected from the customer. The amount of payments to our Representatives were $17.2 million and $12.7 million for the three months ended March 31, 2026 and 2025, respectively.

Typically, we expect to satisfy performance obligations relating to contracts within one year or less, however, timing of performance obligations can vary from timing of payment, production scheduling and timing of customer installation requirements. Increases in contract assets are mainly due to the increased production and increased demand for our BASX-branded products.
4. Leases
The Company has lease arrangements for certain administrative, manufacturing and warehousing facilities and equipment. Lease expiration dates, including expected renewal options, range from January 2029 to April 2033, with the weighted average remaining term being 6.0 years. The discount rates used to calculate the present value of lease payments range from 1.3 % to 6.6 % as of March 31, 2026. All leases are classified as operating leases.

12. Debt
On December 16, 2024, we entered into the Third Amendment to the Amended and Restated Loan Agreement dated November 24, 2021, to include an $80.0 million term loan payable in equal monthly installments, plus interest, over 60 months, expiring December 16, 2029. The agreement provided for a $200.0 million revolving credit facility and an option to increase the maximum borrowings to $300.0 million. In April 2025, we entered into the Fourth Amendment to the Amended and Restated Loan Agreement dated November 24, 2021, to increase our available Revolver to $230.0 million, an increase of $30.0 million, to fund our additional working capital needs.
On May 29, 2025, we entered into the Fifth Amendment to the Amended and Restated Loan Agreement dated November 24, 2021, whereby the remaining balance of the term loan, approximately $72.0 million, was rolled into the amended Revolving Loan (“Amended Revolver”), the capacity of which was increased to $500.0 million from $230.0 million.
On December 29, 2025, we entered into the Sixth Amendment to the Amended and Restated Loan Agreement (as amended, “Amended Loan Agreement”). The terms of the Amendment increased the amount of the borrowing capacity on the Amended Revolver to $600.0 million from $500.0 million by exercising the $100.0 million accordion feature. The Amended Revolver is prepayable without penalty and expires on May 27, 2030.

Interest Rates
Any outstanding loans under the Revolver bear interest at the daily compounded secured overnight financing rate (“SOFR”) plus the applicable margin, with a 10-basis point credit spread adjustment.
Applicable margin, ranging from 1.25 % - 1.75 %, is determined quarterly based on the Company’s leverage ratio. The Company is also subject to letter of credit fees, ranging from 1.25 % - 1.75 %, and a commitment fee, ranging from 0.10 % - 0.20 %. The applicable fee percentage is determined quarterly based on the Company’s leverage ratio.
Fees associated with the unused portion of the committed amount are included in interest expense on our consolidated statements of income and were not material for the three months ended March 31, 2026 and 2025, respectively.
Weighted average interest rate of our borrowings outstanding is as follows:
| Three Months Ended March 31, | ||||||||||||||||||||||||||||||||
| 2026 | 2025 | |||||||||||||||||||||||||||||||
| Revolver | ||||||||||||||||||||||||||||||||
If SOFR cannot be determined pursuant to the definition, as defined by the Amended Loan Agreement, any outstanding effected loans will be deemed to have been converted into alternative base rate (“ABR”) loans. ABR loans would bear interest at a rate per annum equal to the highest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus 0.50 %, or (c) daily simple SOFR for a one-month tenor in effect on such day plus 1.00 %. As of December 16, 2024, as defined by the Amended Loan Agreement, if the SOFR cannot be determined any outstanding balance will bear interest at the Prime Rate in effect on such day.
Debt Covenants
At March 31, 2026, we were in compliance with our financial covenants as defined by the Amended Loan Agreement. These covenants included a financial covenant that we meet certain parameters related to our leverage ratio. At March 31, 2026, our leverage ratio was 1.71 to 1.0, which meets the requirement of not being above 3 to 1.

13. Income Taxes
Income Tax Provision (Benefit)

Rate Reconciliation
The following table reconciles the U.S federal statutory income tax rate to the Company’s effective income tax rate for the three months ended March 31, 2026 and 2025:

| Other | ( | ( | % | % | ||||||||||||||||||||||||||||||||||||||||||||||
| Effective tax rate | % | % | ||||||||||||||||||||||||||||||||||||||||||||||||
The Company’s effective tax rate differs from the statutory rate primarily due to the excess tax benefits of stock transactions and state taxes. Pretax income is all domestic and there are no foreign income effects. No state jurisdictions individually meet the 5% disaggregation threshold. State taxes in Oregon, Oklahoma, Virginia, and Pennsylvania for the three months ended March 31, 2026, and state taxes in Oregon, Indiana, and Pennsylvania for the three months ended March 31, 2025, contributed to the majority (greater than 50%) of the tax effect in the state and local income tax category.
The Company’s estimated annual 2026 effective tax rate, excluding discrete events, is approximately 25.0 %. We file income tax returns in the U.S., state and foreign income tax jurisdictions. We are subject to U.S. income tax examinations for the tax years 2023 to present, and to non-U.S. income tax examinations for the tax years 2022 to present. In addition, we are subject to state and local income tax examinations for tax years 2022 to present. The Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be recognized as a component of income tax expense.

Tax Law Changes
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted, introducing significant amendments to the Internal Revenue Code. In accordance with ASC 740, Income Taxes, the Company recognized the tax effects of the enacted legislation in the period that includes the enactment date.
Impact of Tax Law Changes
The Company measured the effects of the tax law change using the enactment date approach, with a measurement date of June 30, 2025, from the Q2 2025 tax provision calculation as the closest date of measurement for deferred and current values. The measurement resulted in an increase in DTLs of $35.4 million, a decrease in current income tax payable of $36.2 million, and an increase in provision expense of $0.8 million due to the bonus depreciation change effect on Texas Franchise tax and the reduced R&D Tax Credit allowed with the §174A change. Significant provisions of OBBBA affecting the Company include:
•100% Bonus Depreciation: Effective for qualified property acquired after January 19, 2025, including manufacturing equipment, which reverses the previously scheduled phase-down of the bonus depreciation deduction to 40% for 2025 under prior law. This provision increased DTLs by $7.0 million, decreased current payable by $7.0 million, and increased provision expense due to the accelerated tax deductions for capital expenditures made in 2025 and the small provision effect from the change in Texas Franchise Tax and state bonus depreciation. This adjustment also decreased the DTL for the UNICAP inventory calculation by $0.6 million, offset against current income tax payable.
•Permanent Expensing of Domestic R&E Costs (Section 174A): Retroactive to January 1, 2025, resulting in decreased DTAs due to immediate tax deductibility of qualified domestic R&E costs as incurred. This provision decreased DTAs by $3.4 million, decreased current payables by $4.2 million, and increased provision expense by $0.8 million due to the reduction in the R&D tax credit (the Company will revert to the reduced credit method for calculation of the tax credit under the new law).
•Accelerated Deduction of Unamortized Domestic R&E Cost Originally Capitalized in Tax Years 2022, 2023, and 2024 (Section 174A): The Company has elected to deduct the unamortized amounts of Section 174 Costs as of December 31, 2024, fully in tax year 2025, which decreased DTAs and current payables by $25.5 million.
The impact of OBBBA enactment increased the Company’s effective tax rate by 0.7% for the year ended December 31, 2025. Effective January 1, 2026, the OBBBA enacted a 1% charitable contribution floor. The Company has included this permanent difference in the Q1 tax provision calculation, and the change increased the Company’s effective tax rate by 0.1% for the three months ended March 31, 2026.
Net Operating Loss
Due to the favorable changes in tax law related to the OBBBA, as of December 31, 2025, the Company generated Federal and State net operating loss (“NOL”) carryforwards of approximately $57.0 million and $22.5 million, respectively. The Federal NOLs have an indefinite carryforward period but are limited to offsetting 80% of taxable income in any given year under current tax law. The State NOLs have varying expiration dates.
The Company recorded deferred tax assets of $12.0 million (Federal) and $1.1 million (State) related to these NOL carryforwards as of December 31, 2025. As of March 31, 2026, the deferred tax asset balances are $3.6 million (Federal) and $0.5 million (State), considering usage of the NOL’s in the first quarter of 2026. Management has evaluated the positive and negative evidence in assessing the need for a valuation allowance (historical operating results, cumulative losses in recent years, and projected future taxable income) and we believe it is more likely than not that we will recognize the deferred tax assets in tax year 2026.

14. Share-Based Compensation
On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan (as amended, “2007 Plan”) which provided an additional 5.0 million shares that could be granted in the form of stock options, stock appreciation rights, restricted stock awards, performance units, and performance awards. Under the 2007 Plan, the exercise price of shares granted may not be less than 100 % of the fair market value at the date of the grant.
On May 24, 2016, our stockholders adopted the 2016 Long-Term Incentive Plan (“2016 Plan”) which provides for approximately 13.4 million shares, comprised of 5.1 million new shares provided for under the 2016 Plan, approximately 0.6 million shares that were available for issuance under the previous 2007 Plan that are now authorized for issuance under the 2016 Plan, approximately 3.9 million shares that were approved by the stockholders on May 15, 2018, and an additional 3.8 million shares that were approved by the stockholders on May 12, 2020.
On May 21, 2024, our stockholders adopted the 2024 Long-Term Incentive Plan (“2024 Plan”) which provides for approximately 2.7 million new shares and approximately 3.7 million shares that were issued and outstanding under the 2016 Plan (as of May 21, 2024) that are now authorized for issuance under the 2024 Plan. The 3.7 million shares issued and outstanding under the 2016 Plan are only eligible for issuance under the 2024 Plan upon forfeiture, expiration, or cancellation.
Under the 2024 Plan and previously under the 2016 Plan (collectively, the “LTIP Plans”), shares can be granted in the form of stock options, stock appreciation rights, restricted stock awards, performance awards, dividend equivalent rights, and other awards. Under the LTIP Plans, the exercise price of shares granted may not be less than 100% of the fair market value at the date of the grant. The LTIP Plans are administered by the Compensation Committee of the Board of Directors or such other committee of the Board of Directors as is designated by the Board of Directors (the “Committee”). Membership on the Committee is limited to independent directors. The Committee may delegate certain duties to one or more officers of the Company as provided in the LTIP Plans. The Committee determines the persons to whom awards are to be made, determines the type, size and terms of awards, interprets the LTIP Plans, establishes and revises rules and regulations relating to the LTIP Plans and makes any other determinations that it is necessary for the administration of the LTIP Plans.
Options
The following weighted average assumptions were used to determine the fair value of the stock options granted on the original grant date for expense recognition purposes for options granted during the three months ended March 31, 2026 and 2025 using a Black Scholes-Merton Model:

1 Senior Leadership Team (“SLT”) consists of officers and key members of management.
The expected term of the options is based on evaluations of historical and expected future employee exercise behavior. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date. Volatility is based on historical volatility of our stock over time periods equal to the expected life at grant date.

The total pre-tax compensation cost related to unvested stock options not yet recognized as of March 31, 2026, is $31.3 million and is expected to be recognized over a weighted average period of 2.6 years.
The total intrinsic value of options exercised during the three months ended March 31, 2026 and 2025, was $3.5 million and $13.1 million, respectively. The cash received from options exercised during the three months ended March 31, 2026 and 2025, was $3.1 million and $4.4 million, respectively. The impact of these cash receipts is included in financing activities in the accompanying consolidated statements of cash flows.
Restricted Stock
The fair value of restricted stock awards is based on the fair market value of AAON common stock on the respective grant dates, reduced for the present value of dividends. At March 31, 2026, unrecognized compensation cost related to unvested restricted stock awards was approximately $11.6 million which is expected to be recognized over a weighted average period of 2.5 years.

PSUs
We have awarded PSUs to certain officers and employees under our LTIP Plans. Unlike our restricted stock awards, these PSUs are not considered legally outstanding and do not accrue dividends during the vesting period. These PSUs vest based on the level of achievement with respect to the Company's total shareholder return (“TSR”) benchmarked against similar companies included in the capital goods sector of the S&P 400 and S&P 600 building products industry. The TSR measurement period is three years . At the end of the measurement period, each award will be converted into AAON common stock at 0 % to 200 % of the PSUs held, depending on overall TSR as compared to the S&P 400 and S&P 600 building products industry.
The total pre-tax compensation cost related to unvested PSUs not yet recognized as of March 31, 2026, is $8.7 million and is expected to be recognized over a weighted average period of approximately 2.3 years.
The following weighted average assumptions were used to determine the fair value of the PSUs granted on the original grant date for expense recognition purposes for PSUs granted during the three months ended March 31, 2026 and 2025, using a Monte Carlo Model:

| Expected (annual) dividend rate | $ | $ | ||||||||||||||||||
| Expected volatility | ||||||||||||||||||||
| Risk-free interest rate | ||||||||||||||||||||
| Expected life (in years) | ||||||||||||||||||||
The expected term of the PSUs is based on their remaining performance period. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date. Volatility is based on historical volatility of our stock over time periods equal to the expected life at grant date.

15. Employee Benefits
Defined Contribution Plan - 401(k)
We sponsor a defined contribution plan (the “Plan”). Eligible employees may make contributions in accordance with the Plan and IRS guidelines. In addition to the traditional 401(k), eligible employees are given the option of making an after-tax contribution to a Roth 401(k) or a combination of both. The Plan provides for automatic enrollment and for an automatic increase to the deferral percentage at January 1st of each year and each year thereafter. Eligible employees are automatically enrolled in the Plan at a 6.0 % deferral rate and currently contributing employees’ deferral rates will be increased to 6.0 % unless their current rate is above 6.0 % or the employee elects to decline the automatic enrollment or increase. Administrative expenses are paid for by Plan participants. The Company paid no
The Company matches 175.0 % up to 6.0 % of employee contributions of eligible compensation. Additionally, Plan participant forfeitures are used to reduce the cost of the Company contributions.

Profit Sharing Bonus Plans
We maintain a discretionary profit sharing bonus plan under which approximately 8.5 % of pre-tax profit from the Company is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible employees are regular full-time non-exempt employees of the Company who are actively employed and working on the first and last day of the calendar quarter.

We self-insure for our employees’ health insurance, and make medical claim payments up to certain stop-loss amounts. We estimate our self-insurance liabilities using an analysis provided by our claims administrator and our historical claims experience. Eligible employees are regular full-time employees who are actively employed and working. Participants are expected to pay a portion of the premium costs for coverage of the benefits provided under the Plans. In addition, the Company matches 175.0 % of a participating employee's allowed contributions to a qualified health saving account to assist employees with health insurance plan deductibles.

16. Earnings Per Share
Basic net income per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share assumes the conversion of all potentially dilutive securities and is calculated by dividing net income by the sum of the weighted average number of shares of common stock outstanding plus all potentially dilutive securities. Dilutive common shares consist primarily of stock options and restricted stock awards.

18. New Markets Tax Credit
2019 New Markets Tax Credit
On October 24, 2019, the Company entered into a transaction with a subsidiary of an unrelated third-party financial institution (the “2019 Investor”) and a certified Community Development Entity under a qualified New Markets Tax Credit (“2019 NMTC”) program pursuant to Section 45D of the Internal Revenue Code of 1986, as amended, related to an investment in plant and equipment to facilitate the expansion of our Longview, Texas manufacturing operations (the “2019 Project”). In connection with the 2019 NMTC transaction, the Company received a $23.0 million NMTC allocation for the Project and secured low-interest financing and the potential for future debt forgiveness related to the 2019 Project.
Upon closing of the 2019 NMTC transaction, the Company provided an aggregate of approximately $15.9 million to the 2019 Investor, in the form of a loan receivable, with a term of 25 years, bearing an interest rate of 1.0 %. This $15.9 million in proceeds plus capital contributed from the 2019 Investor was used to make an aggregate $22.5 million loan to a subsidiary of the Company. This financing arrangement is secured by equipment at the Company’s Longview, Texas facilities and a guarantee from the Company, including an unconditional guarantee of the NMTCs. The Company’s seven-year compliance period ends in 2026, at which time the Company expects the put/call feature of the transaction to be exercised, forgiving a portion of the debt.
This transaction also includes a put/call feature either of which can be exercised at the end of the seven-year compliance period. The 2019 Investor may exercise its put option or the Company can exercise the call, both of which could serve to trigger forgiveness of a portion of the debt. The 2019 Investor’s interest of $7.5 million is recorded as short-term debt on the consolidated balance sheets. The Company incurred approximately $0.3 million of debt issuance costs related to the above transactions, which are being amortized over the life of the transaction.

This financing arrangement is secured by a guarantee from the Company, including an unconditional guarantee of the NMTCs. The net proceeds from the closing of the 2023 NMTC are included in restricted cash on our consolidated balance sheets required to be used for the 2023 Project.
This transaction also includes a put/call feature either of which can be exercised at the end of the seven-year compliance period. The 2023 Investor may exercise its put option or the Company can exercise the call, both of which could serve to trigger forgiveness of a portion of the debt. The 2023 Investor's interest of $5.8 million is recorded in new markets tax credit obligations on the consolidated balance sheets. The Company incurred
25
approximately $0.4 million of debt issuance costs related to the above transactions, which are being amortized over the life of the transaction.
2024 New Markets Tax Credit
On February 27, 2024, the Company entered into a transaction with a subsidiary of an unrelated third-party financial institution (the “2024 Investor”) and a certified Community Development Entity under a qualified New Markets Tax Credit (“2024 NMTC”) program pursuant to Section 45D of the Internal Revenue Code of 1986, as amended, related to an investment in real estate to facilitate 2023 Project. In connection with the 2024 NMTC transaction, the Company received a $15.5 million NMTC allocation for the 2024 Project and secured low interest financing and the potential for future debt forgiveness related to the expansion of its Longview, Texas facilities.
Upon closing of the 2024 NMTC transaction, the Company provided an aggregate of approximately $11.0 million to the 2024 Investor, in the form of a loan receivable, with a term of 25 years, bearing an interest rate of 1.0 %. This $11.0 million in proceeds plus capital contributed from the 2024 Investor was used to make an aggregate $16.0 million loan to a subsidiary of the Company. This financing arrangement is secured by a guarantee from the Company, including an unconditional guarantee of the NMTCs. The net proceeds from the closing of the 2024 NMTC are included in restricted cash on our consolidated balance sheets required to be used for the 2024 Project.
This transaction also includes a put/call feature that either of which can be exercised at the end of the seven-year compliance period. The Investor may exercise its put option or the Company can exercise the call, both of which could serve to trigger forgiveness of a portion of the debt. The 2024 Investor's interest of $3.9 million is recorded in new markets tax credit obligations on the consolidated balance sheets. The Company incurred approximately $0.4 million of debt issuance costs related to the above transactions, which are being amortized over the life of the transaction.
2026 New Markets Tax Credit
On April 16, 2026 the Company entered into a transaction with a subsidiary of an unrelated third-party financial institution (the “2026 Investor”) and a certified Community Development Entity under a qualified New Markets Tax Credit (“2026 NMTC”) program pursuant to Section 45D of the Internal Revenue Code of 1986, as amended, related to an investment in our Memphis, TN facility. In connection with the 2026 NMTC transaction, the Company received a $50.5 million NMTC allocation for the 2026 Project and secured low interest financing and the potential for future debt forgiveness related to the 2026 Project.
Upon closing of the 2026 NMTC transaction, the Company provided an aggregate of approximately $35.2 million to the 2026 Investor, in the form of a loan receivable, with a term of 27 years, bearing an interest rate of 1.2 %. This $35.2 million in proceeds plus capital contributed from the 2026 Investor was used to make an aggregate $48.2 million loan to a subsidiary of the Company. This financing arrangement is secured by a guarantee from the Company, including an unconditional guarantee of the NMTCs. The net proceeds from the closing of the 2026 NMTC were $12.9 million.
This transaction also includes a put/call feature that either of which can be exercised at the end of the seven-year compliance period. The Investor may exercise its put option or the Company can exercise the call, both of which could serve to trigger forgiveness of a portion of the debt.
The 2019 Investor, 2023 Investor, 2024 Investor and 2026 Investor are each subject to 100 percent recapture of the 2019, 2023, 2024 and 2026 NMTC, respectively, it receives for a period of seven years , as provided in the Internal Revenue Code and applicable U.S. Treasury regulations in the event that the financing facility of the Borrower under the transaction (AAON Coil Products for the 2019, 2023 and 2024 transaction and a portion of the business of AAON Oklahoma for the 2026 transaction) becomes ineligible for NMTC treatment per the Internal Revenue Code requirements. The Company is required to be in compliance with various regulations and contractual provisions that apply to the NMTC arrangements. Noncompliance with applicable requirements could result in the Investors' projected tax benefits not being realized and, therefore, require the Company to indemnify the Investor for any loss or recapture of the NMTC related to the financing until such time as the recapture provisions have expired under the applicable statute of limitations. The Company does not anticipate any credit recapture will be required in connection with any of these financing arrangements.
The Investors and their majority-owned community development entity are considered VIEs and the Company is the primary beneficiary of the VIEs. Because the Company is the primary beneficiary of the VIEs, they have been included in the consolidated financial statements. There are no other assets, liabilities or transactions in these VIEs

19. Commitments and Contingencies
Other Matters
The Company is involved from time to time in claims and lawsuits incidental to our business arising from various matters, including alleged violations of contract, product liability, warranty, environmental, regulatory, personal injury, intellectual property, employment, tax and other laws. We closely monitor these claims and legal actions and frequently consult with our legal counsel to determine whether they may, when resolved, have a material adverse effect on our financial position, results of operations or cash flows and we accrue and/or disclose loss contingencies as appropriate. We do not believe these matters will have a material adverse effect on our business, financial position, results of operations or cash flows.
We are occasionally party to cancellable and occasionally non-cancellable, fixed-price contracts with major suppliers for the purchase of raw material and component parts. We expect to receive delivery of raw materials for use in our manufacturing operations. These contracts are not accounted for as derivative instruments because they meet the normal purchase and normal sales exemption. We had no material contractual purchase obligations as of March 31, 2026, except as noted below.
In 2023, the Company executed a five-year purchase commitment for refrigerants. For the three months ended March 31, 2026 and 2025, the Company made payments of $3.2 million and $0.6 million on this contract, respectively. Estimated minimum future payments are $7.3 million, and $11.2 million for 2026 and 2027, respectively.
In 2025, the Company executed three, one-year purchase commitments for raw materials. Estimated minimum future payments are $23.3 million for 2026. We had no other material contractual purchase obligations as of March 31, 2026.

21. Segments
The Company has determined that it has three reportable segments for financial reporting purposes.
AAON Oklahoma: AAON Oklahoma engineers, manufactures, and sells highly configurable HVAC systems, designs and manufactures controls solutions, and sells aftermarket parts to customers through retail part stores and online. AAON Oklahoma includes operations at the Company’s manufacturing facilities in Tulsa, Oklahoma; Memphis, Tennessee; and Parkville, Missouri, as well as two retail locations, the Norman Asbjornson Innovation Center (“NAIC”), and the Gary D. Fields Customer Exploration Center.
The NAIC is a world-class research and development laboratory accredited by the Air Movement and Control Association International, Inc. ("AMCA"), where our products are continuously tested under extreme environmental conditions to ensure optimal performance, efficiency, and value. The Gary D. Fields Customer Exploration Center showcases the engineering, design attributes, and premium build quality of our equipment alongside market alternatives.
AAON Coil Products: AAON Coil Products engineers and manufactures and sells semi-custom and custom HVAC systems as well as heating and cooling coils for use in HVAC systems, primarily for AAON Oklahoma, AAON Coil Products, and BASX. AAON Coil Products operates from our Longview, Texas manufacturing facilities, which also produce BASX-branded products.
BASX: BASX engineers, manufactures, and sells a wide range of custom, high-performance cooling solutions for the rapidly growing hyperscale data center market; ventilation solutions for cleanroom environments in the biopharmaceutical, semiconductor, medical, and agricultural sectors; and highly customized air handlers and modular solutions for a variety of markets. BASX operates from our manufacturing facilities in Redmond, Oregon, with additional support from facilities in Memphis, Tennessee, and Longview, Texas.
The Company’s chief decision maker (“CODM”), our CEO, allocates resources and assesses the performance of each operating segment using information about the operating segment’s net sales, cost of sales, and gross profit directly attributable to our segments. The CODM does not evaluate operating segments using asset or liability information.
Due to the integrated nature of our Company as well as the increasing production of both AAON and BASX- branded products across different segments, other costs and expenses, such as selling, general and administrative including corporate expense, are evaluated and resources allocated at a consolidated level.
28
The following table summarizes certain financial data related to our segments and significant segment expenses and other segment items regularly reviewed by our CODM. During the fourth quarter of 2025, the Company modified the reporting of sales of coils from AAON Coil Products to AAON Oklahoma to report at cost to be consistent with our other intercompany sales between segments. The revised methodology is intended to better reflect the manner in which the CODM evaluates segment performance and makes resource allocation decisions. As a result of this change, prior period segment results have been recast to conform to the current period presentation. The change did not affect consolidated net sales, cost of sales or gross profit. The cost of sales and gross profit amounts shown below are presented after elimination entries.

Description of the Company
AAON is a leader in HVAC solutions for commercial and industrial indoor environments. The Company’s industry-leading approach to designing and manufacturing highly configurable equipment to meet exact needs creates a premier ownership experience with greater efficiency, performance, and long-term value. AAON is headquartered in Tulsa, Oklahoma, where its world-class innovation center and testing capabilities enable continuous advancement toward a cleaner and more sustainable future.
We engineer, manufacture, and sell premium heating, ventilation, and air conditioning equipment consisting of semi-custom and custom rooftop units, data center cooling solutions, cleanroom systems, packaged outdoor mechanical rooms, air handling units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps, coils, and controls. These products are marketed and sold to a variety of vertical markets including retail, manufacturing, educational, lodging, supermarket, data centers, medical and pharmaceutical, industrial, and other commercial markets. We sell our products to all 50 states in the United States and certain provinces in Canada.
Foreign sales were approximately $11.2 million for the three months ended March 31, 2026, as compared to $11.3 million for the three months ended March 31, 2025.
Our AAON brand can be affected by a number of economic factors, including the level of economic activity in the markets in which we operate. After the commercial and industrial new construction markets came to a standstill in 2020–2021, our core nonresidential end‑markets entered a period of robust growth, increasing by approximately 50.0% between 2022 and 2024. By late 2024, however, these markets began to contract, and the softening continued through 2025, though at a moderate rate. While leading indicators signal a stabilization in activity, we have not observed clear indications of a significant reacceleration. Furthermore, signals from general economic indicators are mixed regarding the health of the general economy. If the domestic economy were to slow or enter a recession, this could further impact our new construction markets and also weigh on the replacement market, potentially resulting in reduced sales volumes and profitability. Sales in the commercial and industrial new construction markets generally lag behind the housing market, which in turn is influenced by cyclical factors such as interest rates, inflation, consumer spending habits, employment rates, the state of the economy and other macroeconomic factors over which we have no control. Sales in the replacement markets are driven by various factors, including general economic growth, the Company's new product introductions, fluctuations in the average age of existing equipment in the market, government regulations and stimulus, change in market demand between more customized, higher performing HVAC equipment and lower priced standard equipment, as well as many other factors. When new construction is down, we emphasize the replacement market.
Our BASX brand is heavily dependent on the data center market. The growing maturity and adoption of Artificial Intelligence and high-performance compute is driving profound innovation across the data center market, resulting in increased demand for our products and solutions. Between 2022 and 2025, total put‑in‑place construction spending for data centers expanded by approximately 240.0%, and present indicators suggest continued strength with no meaningful signs of slowing in the foreseeable future. In response, we have made substantial capital investments to expand our capacity and ensure we are fully equipped to support this accelerating growth trajectory.
31
We sell our products to property owners and contractors mainly through a network of independent manufacturers’ Representatives. This go-to-market strategy is unique compared to most of our larger competitors in that most control their sales channel. We value the independent sales channel as we think it is a more effective way of increasing market share. Although we concede full control of the sales process with this strategy, the entrepreneurial aspect of the independent sales channel attracts the most talent and provides greater financial incentives for its salespeople. Further, the independent sales channel sells different types of equipment from various manufacturers, allowing it to operate with more of a solutions-based mindset, as opposed to an internal sales department of a manufacturing company that is incentivized to only sell its equipment regardless if it is the best solution for the end customer. We also have a small internal sales force that supports the relationships between the Company and our sales channel partners. BASX sells highly customized products for unique applications for a more concentrated customer base and an internal sales force is more effective for such products.
The principal components of cost of sales are labor, raw materials, component costs, factory overhead, freight out, and engineering expense. The principal high volume raw materials used in our manufacturing processes are steel, copper, and aluminum, and are obtained from domestic suppliers. We also purchase from domestic manufacturers certain components, including coils, compressors, motors, and electrical controls.
The price levels of our raw materials fluctuate due to various economic factors within the U.S. and global economy. At March 31, 2026, the price for copper and aluminum increased by approximately 7.1% and 18.8%, respectively, while stainless steel and galvanized steel decreased approximately 11.6% and 3.5%, respectively.
We attempt to limit the impact of price fluctuations on these materials by entering into cancellable and non-cancellable contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw materials from our contracts for use in our manufacturing operations.
We occasionally increase the price of our products to help offset any inflationary headwinds. In recent years, price increases have been more frequent due to the amount of inflation the business has endured. On January 1, 2025, we implemented a 3.0% price increase for AAON-branded products. On April 1, 2025, we implemented a 6.0% surcharge on all AAON-branded products as a result of the uncertainty of international tariffs. BASX-branded products are priced by job and in most cases, provide the ability to increase the price if the order is outside normal lead times.
Macroeconomic Conditions
Beginning in January 2025, the current United States (“U.S.”) Administration began enacting a series of tariffs affecting nearly all goods imported into the U.S. In retaliation, numerous foreign countries imposed reciprocal tariffs and restricted certain exports to the U.S. The continuous changes and uncertainty in tariff policy could impact our cost of materials, parts, or components imported into the U.S. and could impact the availability of supply from our vendors. We source raw materials domestically, but historically have seen those suppliers increase prices when tariffs are increased. Additionally, while we source most components domestically, our vendors may be impacted by tariffs if they use foreign parts and materials and often pass any additional costs as a result of tariffs through to us. We expect to continue to pass along some of these costs to our customers, but the increased price of our products could adversely affect the demand, which could have an adverse effect on our business and our earnings. The third quarter of 2025 is the first period for us to see any significant financial impact from tariffs. On April 1, 2025 we instituted a 6.0% tariff surcharge on AAON-branded orders which we began to see realization of in the third quarter of 2025. Early in 2025, the amount of surcharge realized had not covered the additional costs from the tariffs, but had changed by the end of the year as we fully realized our surcharge.
We make strategic purchases of materials when we see opportunities or potential disruptions in our supply chain. We have experienced supply chain challenges related to specific manufacturing parts, which could be exacerbated by the trade conflict. We manage our supply chain challenges through strong vendor relationships as well as expanding our list of available vendors.

•Income from operations as a percent of sales increased to 11.5% compared to 10.9% a year ago, reflecting higher production volumes and improving execution.
•We have a strong balance sheet with a leverage ratio of 1.71 and available borrowings under our Revolver of $173.5 million.

We report our financial results based on three reportable segments: AAON Oklahoma, AAON Coil Products, and BASX, which are further described in “Segments” (Note 21) within our notes to the consolidated financial statements. The Company’s chief operating decision maker (“CODM”), our CEO, allocates resources and assesses the performance of each operating segment using information about the operating segment's net sales and gross profit. The CODM does not evaluate operating segments using asset or liability information.

1 Cost of sales and gross profit for each segment are calculated as a percentage of the respective segment’s net sales. Total cost of sales and total gross profit are calculated as a percentage of total net sales.
2 Presented after intercompany eliminations.
Total net sales increased $174.9 million, or 54.3% driven by growth across all segments. AAON Oklahoma saw significant improvement with an increase of $82.1 million in net sales driven by increased production out of the Tulsa facility and a stronger backlog heading into 2026. AAON-branded products struggled in the first quarter of 2025 due to the change in refrigerant. The $23.6 million increase in net sales for AAON Coil Products is due to sales of BASX-branded products for liquid cooling data center orders. BASX net sales are up $69.2 million due to the production of BASX-branded products from our Memphis facility.
Gross profit as a percentage of sales is stable at 25.1% compared to 26.8% in the same period a year ago. AAON Oklahoma gross profit margin is up slightly to 26.3% due to realization of price increases and increased volume out of the Tulsa facility. However, AAON Oklahoma also carries the overhead related to the Memphis plant as all Memphis sales are intercompany transactions done at cost and are reflected within the BASX segment. The approximate overhead related to the Memphis plant is $9.8 million. BASX gross profit margin remained flat year-over-year with additional costs related to outsourcing which limited the benefits realized by the additional volume.

Selling, general and administrative expenses as a percentage of sales are down year-over-year from 15.9% in 2025 to 13.7% in 2026. The dollar increase of $16.6 million is primarily driven by higher salaries and benefits, including profit sharing and stock compensation. Profit sharing is up as a result of our higher earnings in the period. Salaries and benefits have increased as we add additional headcount to help build out our organizational capacity for future growth.

The Company’s estimated annual 2026 effective tax rate, excluding discrete events, is expected to be approximately 25.0 %. Discrete events such as excess tax benefits related to stock compensation and various tax credits consistently provide a benefit, keeping our actual effective rate lower than the stated 25.0 %.
Liquidity and Capital Resources
Our working capital and capital expenditure requirements are generally met through net cash provided by operations and the use of the revolving bank line of credit based on our current liquidity at the time.
Working Capital - Our unrestricted cash and cash equivalents remained stable from December 31, 2025 to March 31, 2026.
35
Outstanding Debt - On December 16, 2024, we entered into the Third Amendment and Restated Loan Agreement dated November 24, 2021, to include an $80.0 million term loan payable in equal monthly installments, plus interest, over 60 months, expiring December 16, 2029 (“Term Loan”). The agreement provided for a $200.0 million revolving credit facility and an option to increase the maximum borrowings to $300.0 million. In April 2025, we increased our available Revolver to $230.0 million, an increase of $30.0 million, to fund our additional working capital needs.
On May 29, 2025, we entered into the Fifth Amendment to the Amended and Restated Loan Agreement dated November 24, 2021 (as amended, “Amended Loan Agreement”) whereby the remaining balance of the Term Loan, approximately $72.0 million, was rolled into the amended Revolving Loan (“Amended Revolver”), the capacity of which was increased from $230.0 million to $500.0 million. The Amended Revolver is prepayable without penalty.
On December 29, 2025, we entered into the Sixth Amendment to the Amended and Restated Loan Agreement. The terms of the Amendment increased the amount of the borrowing capacity on the Revolver from $500.0 million to $600.0 million by exercising the $100.0 million accordion feature. The Amended Revolver is prepayable without penalty. The Revolver expires on May 27, 2030.
As of March 31, 2026, and December 31, 2025, we had an outstanding balance under the Revolver of $425.2 million and $398.3 million, respectively. We had two standby letters of credit totaling $1.3 million and one standby letter of credit totaling $0.7 million as of March 31, 2026, and December 31, 2025, respectively. Borrowings available under the Revolver at March 31, 2026, were $173.5 million.
Any outstanding loans under the Revolver bear interest at the daily compounded secured overnight financing rate (“SOFR”) plus the applicable margin, with a 10 basis point credit spread adjustment.
Applicable margin, ranging from 1.25% - 1.75%, is determined quarterly based on the Company’s leverage ratio. The Company is also subject to letter of credit fees, ranging from 1.25% - 1.75%, and a commitment fee, ranging from 0.10% - 0.20%. The applicable fee percentage is determined quarterly based on the Company’s leverage ratio.
Fees associated with the unused portion of the committed amount are included in interest expense on our consolidated statements of income for the three and three months ended March 31, 2026 and 2025.
Weighted average interest rate of our borrowings outstanding are as follows:
| Three Months Ended March 31, | ||||||||||||||||||||||||||||||||
| 2026 | 2025 | |||||||||||||||||||||||||||||||
| Revolver | 5.3% | 5.6% | ||||||||||||||||||||||||||||||
If SOFR cannot be determined pursuant to the definition, as defined by the Amended Loan Agreement, any outstanding effected loans will be deemed to have been converted into alternative base rate (“ABR”) loans. ABR loans would bear interest at a rate per annum equal to the highest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus 0.50%, or (c) daily simple SOFR for a one-month tenor in effect on such day plus 1.00%. As of December 16, 2024, as defined by the Amended Loan Agreement, if the SOFR cannot be determined any outstanding balance will bear interest at the Prime Rate in effect on such day.
At March 31, 2026, we were in compliance with our financial covenants, as defined by the Revolver. These covenants require that we meet certain parameters related to our leverage ratio. At March 31, 2026, our leverage ratio was 1.71 to 1.0, which meets the requirement of not being above 3 to 1.

Cash Flows from Operating Activities
The Company currently manages cash needs through working capital as well as drawing on its line of credit. Collections and payments cycles are on a normal pattern and fluctuate due to timing of receipts and payments. Historically, the Company increases the purchase of inventory to take advantage of favorable pricing opportunities and also to mitigate the impact of future supply chain disruptions on our operations. Additionally, we continue to make significant purchases of inventory related to data center orders. These purchases are allocated to customer jobs and show as increases to our contract assets.
Current payment terms for some BASX-branded jobs primarily require the Company to fund the upfront working capital resulting in cash outflows related to our contract assets. Similarly, some BASX-branded jobs require down payments, resulting in cash inflows related to our contract liabilities. The Company experienced carrying working capital for extended periods of time during this period of growth and expansion at our Longview and Memphis plants.

Cash Flows from Investing Activities
Capital expenditures during the three months ended March 31, 2026, relate to continued build out of our Memphis, Tennessee facility and maintenance of our Tulsa facility. We continue to make investments to purchase and develop software for internal use in anticipation of future Company growth.
Our capital expenditure program for 2026 is estimated to be approximately $190.0 million. Many of these projects are subject to review and cancellation at the discretion of our CEO and Board of Directors without incurring substantial charges.
Cash Flows from Financing Activities
The change in cash from financing activities in 2026 is primarily related to borrowings under our revolving credit facility to manage our working capital needs, especially strategic purchases of inventory to avoid supply chain delays and the funding of certain capital expenditures, offset by repayments we were able to make due to our operating results and financial condition.
Furthermore, cash flows from financing activities is historically affected by the timing of stock options exercised by our employees and our regular quarterly dividend.
Commitments and Contractual Agreements
We are occasionally party to short-term and long-term, cancellable and occasionally non-cancellable, contracts with suppliers for the purchase of raw material and component parts. We expect to receive delivery of raw material and component parts for use in our manufacturing operations. These contracts are not accounted for as derivative instruments because they meet the normal purchase and normal sales exemption. We had no material contractual purchase obligations as of March 31, 2026, except as described below.
In 2023, the Company executed a five-year purchase commitment for refrigerants. For the three months ended March 31, 2026 and 2025, the Company made payments of $3.2 million and $0.6 million on this contract, respectively. Estimated minimum future payments are $7.3 million, and $11.2 million for 2026 and 2027, respectively.
In 2025, the Company executed three one-year purchase commitments for raw materials. Estimated minimum future payments are $23.3 million for 2026. We had no other material contractual purchase obligations as of March 31, 2026.
Critical Accounting Estimates
