AAON, Inc. and Subsidiaries
Notes to the Consolidated Financial Statements
(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 five variable interest entities ("VIEs") (Note 16) 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, 2022 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, 2022. 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 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.
Use of Estimates
The preparation of 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, medical insurance accrual, income taxes, useful lives of property, plant, and equipment, estimated future use of leased property, share-based compensation, business combinations, revenue percentage of completion and estimated costs to complete. Actual results could differ materially from those estimates.
Inflation and Labor Market
In 2022 and continuing into 2023, we have witnessed increases in our raw material and component prices. Due to our favorable liquidity position, we continue to make strategic purchases of materials when we see opportunities. We continue to manage the increase in the cost of raw materials through price increases for our products. We have also experienced supply chain challenges related to specific manufacturing parts, which we have managed through our strong vendor relationships as well as expanding our list of vendors.
- 5 -

Additionally, we continue to experience challenges in a tight labor market, especially the hiring of both skilled and unskilled production labor. We have implemented the following wage increases to remain competitive and to attract and retain employees:
•In March 2022, we awarded annual merit raises for an overall 3.0% increase to wages.
•In October 2022, we implemented a cost of living increase of 3.5% in place for all employees
below the Senior Leadership Team ("SLT") level.
•In March 2023, we awarded annual merit raises for an overall 3.9% increase to wages.
We will continue to implement human resource initiatives to retain and attract labor to further increase production capacity. Beginning in 2023, initiatives included changing our employee paid time off policy, historically awarded in arrears at the beginning of each quarter, to accrue ratably over each pay period. Additionally, we enhanced our benefits for short-term disability, life insurance, paid parental leave, and paid military leave.
Despite efforts to mitigate the impact of inflation, supply chain issues and the tight labor market, future disruptions, while temporary, could negatively impact our consolidated financial position, results of operations and cash flows.
Change in Estimate
During the first quarter of 2022, a review of the Company’s useful lives for certain sheet metal manufacturing equipment at our Longview, Texas location resulted in a change in estimate that increased the useful lives from between ten and twelve years to fifteen years. This determination was based on recent and estimated future production levels as well as management’s knowledge of the equipment and historical and future use of the equipment. The change in estimate was made prospectively and resulted in a decrease to depreciation expense within cost of sales on our consolidated statements of income of $1.8 million during the nine months ended September 30, 2022.
WH Series and WV Series Water Source Heat Pump Units
As part of the normal course of business, management continually monitors the profitability of the Company's various product series offerings. During the third quarter of 2022, management made the decision to no longer produce our small packaged geothermal/water-source heat pump units consisting of the WH Series horizontal configuration and WV Series vertical configuration, from one-half to 12 1/2 tons ("WH/WV"). These WH/WV units were produced solely out of the AAON Oklahoma facility. Production of the remaining WH/WV backlog was completed during the second quarter 2023.
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, 2022.
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 revolving line of credit, and other payables, approximate 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 property, plant and equipment, intangible assets, contingent consideration, and goodwill acquired in a business combination.
- 6 -

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.
Definite-Lived Intangible Assets
Our definite-lived intangible assets include various trademarks, service marks, and technical knowledge acquired in business combinations. We amortize our definite-lived intangible assets on 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 | 30 years
Customer relationships | 14 years

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 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.
The changes in the carrying amount of goodwill were as follows:

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 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.
For all other products that are part sales or standardized units, the Company recognizes revenue, presented net of sales tax, when it satisfies the performance obligation in its contracts. As 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.
Historically, sales of our products were moderately seasonal with the peak period being May-October of each year due to timing of construction projects being directly related to warmer weather. However, in recent years, given the increases in demand of our product and increases in our backlog, sales have become more constant throughout the year.
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 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 additional 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 a 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. 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 $20.1 million and $10.8 million for the three months ended September 30, 2023 and 2022, respectively, and $46.4 million and $28.7 million for the nine months ended September 30, 2023 and 2022, respectively.
3. Leases
The Company has various lease arrangements for certain manufacturing and warehousing facilities, equipment rental, as well as administrative facilities. Currently, all leases are classified as operating leases.
The following table presents the balances by lease type:

|  | Balance Sheet Classification |  | September 30, 2023 |  | December 31, 2022

Since 2018, the Company has leased the manufacturing, engineering and office space used by our operations in Parkville, Missouri, which is classified as an operating lease. In October 2022, the Parkville, Missouri lease was amended to expand our manufacturing and office space from 51,000 square feet to 86,000 square feet. The amended lease provides for approximately 31,000 square feet of additional manufacturing and engineering space and approximately 4,000 square feet of additional office space. The amended lease extends the lease term through December 31, 2032.

Total | $ | 16,247 |  |  | $ | 11,508 |

10. Revolving Credit Facility
On May 27, 2022, we amended our $100.0 million Amended and Restated Loan Agreement dated November 24, 2021 (as amended, “Revolver”), to provide for maximum borrowings of $200.0 million. As of September 30, 2023 and December 31, 2022, we had $78.4 million and $71.0 million outstanding under the Revolver, respectively. We have two standby letters of credit totaling $2.3 million as of September 30, 2023. Borrowings available under the Revolver at September 30, 2023 were $119.3 million. The Revolver expires on May 27, 2027. On April 20, 2023, we amended the Revolver to allow for the occurrence of transactions associated with the New Markets Tax Credit executed on April 25, 2023 (Note 16).
Any outstanding loans under the Revolver bear interest at the daily compounded secured overnight financing rate ("SOFR") plus the applicable margin. 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. The weighted average interest rate on borrowings outstanding on the Revolver was 6.5% and 6.3% for the three and nine months ended September 30, 2023, respectively, as compared to 3.5% and 2.5% for the three and nine months ended September 30, 2022, respectively. 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 nine months ended September 30, 2023 and 2022.
If SOFR cannot be determined pursuant to the definition, as defined by the Revolver agreement, any outstanding affected 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%.
- 13 -

At September 30, 2023, we were in compliance with our covenants, as defined by the Revolver. Our financial covenants require that we meet certain parameters related to our leverage ratio. At September 30, 2023, our leverage ratio was 0.33 to 1.0, which meets the requirement of not being above 3 to 1.
11. Income Taxes
The provision (benefit) for income taxes consists of the following:

| Three Months Ended |  | Nine Months Ended
| September 30, 2023 |  | September 30, 2022 |  | September 30, 2023 |  | September 30, 2022
| (in thousands)
Current | $ | 14,892 |  |  | $ | 8,763 |  |  | $ | 33,364 |  |  | $ | 17,849 |
Deferred | 521 |  |  | (436) |  |  | (3,917) |  |  | (563) |
Income tax provision | $ | 15,413 |  |  | $ | 8,327 |  |  | $ | 29,447 |  |  | $ | 17,286 |

The provision for income taxes differs from the amount computed by applying the Federal statutory income tax rate before the provision for income taxes.
The reconciliation of the Federal statutory income tax rate to the effective income tax rate is as follows:

| Three Months Ended |  | Nine Months Ended
| September 30, 2023 |  | September 30, 2022 |  | September 30, 2023 |  | September 30, 2022
Federal statutory rate | 21.0 | % |  | 21.0 | % |  | 21.0 | % |  | 21.0 | %
State income taxes, net of Federal benefit | 3.4 |  |  | 5.0 |  |  | 4.0 |  |  | 4.7 |
Excess tax benefits related to share-based compensation (Note 12) | (0.8) |  |  | (1.5) |  |  | (3.9) |  |  | (1.6) |
Return to provision | 0.9 |  |  | (0.4) |  |  | 0.3 |  |  | (0.5) |
Research and development credits | (0.2) |  |  | (0.7) |  |  | (0.9) |  |  | (1.0) |
Change in valuation allowance (Oklahoma Investment Credit) | — |  |  | — |  |  | (2.0) |  |  | — |
Other | — |  |  | (0.1) |  |  | (0.1) |  |  | (0.7) |
Effective tax rate | 24.3 | % |  | 23.3 | % |  | 18.4 | % |  | 21.9 | %

We have historically earned investment tax credits from the state of Oklahoma’s manufacturing property investment program. We use the flow-through method to account for investment tax credits earned on eligible tangible asset expenditures. Under this method, the investment tax credits are recognized as a reduction to our Oklahoma income tax expense in the year they are used. As part of our expansion projects in Oklahoma, we identified a separate, more advantageous Oklahoma credit program (non income tax related) which will cause us to discontinue our accumulation of credits for Oklahoma’s manufacturing property investment program after the 2022 tax year.
The Company had investment tax credit carryforwards with a valuation allowance reserved against them as we did not have sufficient taxable income to utilize the carryforwards, in part because we generated more credit each year than we were able to utilize. Because the Company will not generate additional excess credits after our 2022 tax year, we will be able to use our credit carryforwards against future taxable income and the related valuation allowance was reversed resulting in a one-time benefit of $3.1 million to the income tax provision for the nine months ended September 30, 2023. As of September 30, 2023, we have investment tax credit carryforwards of approximately $3.8 million. These credits have estimated expirations from the year 2039 through 2043.
The Company's estimated annual 2023 effective tax rate, excluding discrete events, is approximately 24.1%. We file income tax returns in the U.S., state and foreign income tax returns jurisdictions. We are subject to U.S. income tax examinations for tax years 2019 to present, and to non-U.S. income tax examinations for the tax years 2018 to present. In addition, we are subject to state and local income tax examinations for the tax years 2018 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.

12. Share-Based Compensation
As discussed in Note 15, the Company declared a three-for-two stock split effective August 16, 2023. All share and per share information has been updated to reflect the effect of this stock split.
On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan (“LTIP”) 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 LTIP, the exercise price of shares granted could 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 LTIP 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.
Under the 2016 Plan, 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 2016 Plan, the exercise price of shares granted may not be less than 100% of the fair market value at the date of the grant. The 2016 Plan is 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 2016 Plan. The Committee determines the persons to whom awards are to be made, determines the type, size and terms of awards, interprets the 2016 Plan, establishes and revises rules and regulations relating to the 2016 Plan and makes any other determinations that it believes necessary for the administration of the 2016 Plan.
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 nine months ended September 30, 2023 and 2022 using a Black Scholes-Merton Model:

| Nine months ended
| September 30, 2023 |  | September 30, 2022
Directors and SLT 1: |  |  |
Expected (annual) dividend rate | $0.32 |  | $0.25
Expected volatility | 37.89% |  | 36.00%
Risk-free interest rate | 4.39% |  | 2.21%
Expected life (in years) | 4.0 |  | 4.0
Employees: |  |  |
Expected (annual) dividend rate | $0.32 |  | $0.25
Expected volatility | 38.30% |  | 37.38%
Risk-free interest rate | 4.41% |  | 2.20%
Expected life (in years) | 3.0 |  | 3.0
1 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.

A summary of stock option activity under the plans is as follows:

Stock Options | Shares |  | Weighted Average Exercise Price
Outstanding at December 31, 2022 | 4,560,520 |  |  | $ | 30.14 |
Granted | 326,506 |  |  | 61.16 |

Exercisable at September 30, 2023 | 2,273,691 |  |  | $ | 28.32 |

The total pre-tax compensation cost related to unvested stock options not yet recognized as of September 30, 2023 is $10.7 million and is expected to be recognized over a weighted average period of approximately 1.3 years.
The total intrinsic value of options exercised during the nine months ended September 30, 2023 and 2022 was $27.6 million and $6.7 million, respectively. The cash received from options exercised during the nine months ended September 30, 2023 and 2022 was $25.3 million and $11.0 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, Inc. common stock on the respective grant dates, reduced for the present value of dividends. At September 30, 2023, unrecognized compensation cost related to unvested restricted stock awards was approximately $5.7 million, which is expected to be recognized over a weighted average period of approximately 1.5 years.
A summary of the unvested restricted stock awards is as follows:

| Shares |  | Weighted Average Grant Date Fair Value
Unvested at December 31, 2022 | 217,168 |  |  | $ | 33.34 |
Granted | 73,633 |  |  | 59.70 |

PSUs
We have awarded performance restricted stock units ("PSUs") to certain officers and employees under our 2016 Plan. 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 SmallCap 600 Index. The TSR measurement period is three years. At the end of the measurement period, each award will be converted into common stock at 0% to 200% of the PSUs held, depending on overall TSR as compared to the S&P SmallCap 600 Index benchmark companies.
The total pre-tax compensation cost related to unvested PSUs not yet recognized as of September 30, 2023 is $5.0 million and is expected to be recognized over a weighted average period of approximately 1.7 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 nine months ended September 30, 2023 and 2022 using a Monte Carlo Model:

| Nine months ended
| September 30, 2023 |  | September 30, 2022
Expected (annual) dividend rate | $0.32 |  | $0.25
Expected volatility | 32.71% |  | 37.60%
Risk-free interest rate | 4.66% |  | 2.00%
Expected life (in years) | 2.8 |  | 2.8

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.
A summary of the unvested PSUs is as follows:

| Shares |  | Weighted Average Grant Date Fair Value
Unvested at December 31, 2022 | 93,982 |  |  | $ | 36.62 |
Granted | 58,130 |  |  | 84.42 |

Key Employee Awards
As part of the December 2021 acquisition of BASX, the Company granted awards to key employees of BASX ("Key Employee Awards"). Unlike our restricted stock awards under the 2016 Plan, the Key Employee Awards are not considered legally outstanding and do not accrue dividends during the vesting period. The potential future issuance of the Key Employee Awards is contingent upon BASX meeting certain post-closing earn-out milestones during each of the years ending 2021, 2022 and 2023 as defined by the BASX acquisition membership interest purchase agreement ("MIPA Agreement") and continued employment with the Company. At the end of the earn-out period, ending December 31, 2023, each eligible Key Employee Award will vest and be converted into common stock. The fair value of Key Employee Awards is based on the fair market value of AAON common stock on the grant date.
The total pre-tax compensation cost related to unvested Key Employee Awards not yet recognized as of September 30, 2023 is $0.3 million and is expected to be recognized over a weighted average period of approximately 0.3 years.

Total | $ | 494 |  |  | $ | 534 |  |  | $ | 6,319 |  |  | $ | 1,253 |

Share-based compensation expense is recognized on a straight-line basis over the service period of the related share-based compensation award. Historically, stock options and restricted stock awards, granted to employees, vested at a rate of 20% per year. Restricted stock awards granted to directors historically vested one-third each year or, if granted on or after May 2019, vest over the shorter of directors' remaining elected term or one-third each year. As of March 2021, all new grants of stock options and restricted stock awards, granted to employees, vest at a rate of 33.3% per year. Forfeitures are accounted for as they occur.
Historically, if the employee or director is retirement eligible (as defined by the applicable LTIP or 2016 Plan) or becomes retirement eligible during the service period of the related share-based compensation award, the service period (and compensation expense recognition) is the lesser of 1) the grant date, if retirement eligible on grant date, or 2) the period between grant date and retirement eligible date. All stock options and restricted stock awards granted on or after March 1, 2020 to retirement eligible employees or directors contain a one-year employment requirement (minimum service period) or the entire award is forfeited. Forfeitures are accounted for as they occur.
The PSUs cliff vest on December 31, at the end of the third year from the date of grant. Share-based compensation expense is recognized on a straight-line basis over the service period of PSUs. The PSUs are subject to several service and market conditions, as defined by the PSU agreement, which allows the holder to retain a pro-rata amount of awards as a result of certain termination conditions, retirement, change in common control, or death. Forfeitures are accounted for as they occur.
- 18 -

The Key Employee Awards cliff vest on December 31, 2023. Share-based compensation expense is recognized on a straight-line basis over the service period of the Key Employee Awards when it is probable that the performance conditions will be satisfied. The Key Employee Awards are subject to several service and performance conditions, as defined by the Key Employee Award agreement, which allows the holder to retain an amount of the awards as a result of certain termination conditions or change in common control. Forfeitures are accounted for as they occur.
13. 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% deferral rate and currently contributing employees deferral rates will be increased to 6% unless their current rate is at or above 6% or the employee elects to decline the automatic enrollment or increase. Administrative expenses are paid for by Plan participants. The Company paid no administrative expenses during the nine months ended September 30, 2023 and 2022.
The Company matches 175% up to 6% 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 10% of pre-tax profit from AAON Oklahoma and AAON Coil Products is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible employees are regular full-time employees of AAON Oklahoma or AAON Coil Products who are actively employed and working on the first and last days of the calendar quarter and who were employed full-time for at least three full months prior to the beginning of the calendar quarter, excluding the Company's senior leadership team.
BASX has a separate employee incentive program (EIP) under which 5% of BASX's pre-tax profit, plus certain add backs, is paid ratably to eligible employees based on days-of-pay during the fiscal year. Eligible employees are regular full-time and part-time employees who have worked during the year and are still employed when the EIP payment is made following the end of the fiscal year, excluding members of BASX's senior leadership team and any employee paid commissions or royalties.

Employee Medical Plan
At AAON Oklahoma and AAON Coil Products, 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% of a participating AAON Oklahoma and AAON Coil Products employee's allowed contributions to a qualified health saving account to assist employees with health insurance plan deductibles.
BASX is insured for healthcare coverage through a third party. Eligible employees are regular full-time employees who are actively employed and working.

14. 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.
The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2023 and 2022:

15. Stockholders’ Equity
Stock Repurchases
The Board has authorized one active stock repurchase program for the Company. The Company may purchase shares on the open market from time to time. The Board must authorize the timing and amount of these purchases and all repurchases are in accordance with the rules and regulations of the SEC allowing the Company to repurchase shares from the open market.
Our open market repurchase programs are as follows:

Effective Date |  | Authorized Repurchase $ |  | Expiration Date

The Company repurchases shares of AAON, Inc. stock from employees for payment of statutory tax withholdings on stock transactions. All other repurchases from directors or employees are contingent upon Board approval. All repurchases are done at current market prices.
Lastly, the Company also had a stock repurchase arrangement by which employee-participants in our 401(k) savings and investment plan were entitled to have shares in AAON, Inc. stock in their accounts sold to the Company. The 401(k) Plan was amended in June 2022 to discontinue this program. No additional shares have been purchased by the Company under this arrangement since June 2022.

On July 7, 2023, the Board of Directors declared a three-for-two stock split of the Company's common stock to be paid in the form of a stock dividend. Stockholders of record at the close of business on July 28, 2023 received one additional share for every two shares they held as of that date on August 16, 2023 (ex-dividend date August 17, 2023). Cash was paid in lieu of fractional shares (approximately $0.5 million). All share and per share information has been updated to reflect the effects of this stock split. The retroactive effect of the stock split resulted in an approximately $0.1 million reclass between common stock and retained earnings within stockholders' equity on the consolidated balance sheet.
Contingent Shares Issued in BASX Acquisition
As discussed above, the Company declared a three-for-two stock split effective August 16, 2023. All share and per share information has been updated to reflect the effect of this stock split.
In December 2021, we closed on the acquisition of BASX. Under the MIPA Agreement, we committed to $78.0 million in the aggregate of contingent consideration to the former owners of BASX, which is payable in approximately 1.56 million shares of the Company's common stock, par value $0.004 per share. The shares do not accrue dividends.
Under the MIPA Agreement, the potential future issuance of the shares is contingent upon BASX meeting certain post-closing earn-out milestones during each of the years ended 2021, 2022, and 2023. Based on the final allocation of the consideration paid, we estimated the fair value of contingent consideration related to these shares to be approximately $60.0 million, which is included in additional paid-in capital on the consolidated balance sheets. As of September 30, 2023, 0.58 million shares and 0.73 million shares related to the earn-out milestones for the years ended 2022 and 2021, respectively, have been issued to the former owners of BASX as private placements exempt from registration with the SEC under Rule 506(b), which are included in common stock on the consolidated statements of stockholders' equity.
16. 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 twenty-five 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.
- 22 -

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 $6.5 million is recorded in New market tax credit obligation 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.
2023 New Markets Tax Credit
On April 25, 2023, the Company entered into a transaction with a subsidiary of an unrelated third-party financial institution (the “2023 Investor”) and a certified Community Development Entity under a qualified New Markets Tax Credit (“2023 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 “2023 Project”). In connection with the 2023 NMTC transaction, the Company received a $23.0 million NMTC allocation for the 2023 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 2023 NMTC transaction, the Company provided an aggregate of approximately $16.7 million to the Investor, in the form of a loan receivable, with a term of twenty-five years, bearing an interest rate of 1.0%. This $16.7 million in proceeds plus capital contributed from the 2023 Investor was used to make an aggregate $23.8 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 2023 NMTC is 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 $5.7 million is recorded in New market tax credit obligation 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.
The 2019 Investor and 2023 Investor are each subject to 100 percent recapture of the 2019 and 2023 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, Inc.) 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 2019 NMTC arrangements and 2023 NMTC arrangements, respectively. Noncompliance with applicable requirements could result in the 2019 and/or 2023 Investors' projected tax benefits not being realized and, therefore, require the Company to indemnify the 2019 Investor and 2023 Investor for any loss or recapture of the 2019 NMTC and 2023 NMTC, respectively, 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 either of these financing arrangements.
The 2019 Investor and 2023 Investor and its 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 outside of the financing transactions executed as part of the 2019 NMTC or 2023 NMTC arrangements, respectively.
17. Commitments and Contingencies
Havtech Litigation
On January 24, 2022, one of the Company’s former independent sales representative firms, Havtech, LLC (and its affiliate, Havtech Parts Division, LLC, collectively “Plaintiffs”), filed a complaint (the “Complaint”) in the Circuit Court for Howard County, Maryland (Havtech, LLC, et al., v. AAON, Inc., et al.). The Complaint challenged the Company’s termination of its business relationship with Plaintiffs. The Company removed the action to the United States District Court for the District of Maryland (Northern Division) and moved to dismiss the Complaint. Plaintiffs’ First Amended Complaint (“First Amended Complaint”) was entered by the court on July 28, 2022. The First Amended Complaint asserts that the Company improperly terminated Plaintiffs and seeks damages alleged to be no less than $48.6 million, plus fees and costs. The Company filed its Answer to First Amended Complaint on January 31, 2023.
On September 28, 2023, the parties attended a court ordered settlement conference and agreed to resolve the case for $7.5 million. A settlement agreement was entered into on October 25, 2023 and the case has been dismissed with prejudice. The settlement of $7.5 million has been included in accrued liabilities on our consolidated balance sheets and selling, general and administrative expenses on our consolidated statement of income. The final payment was made on October 26, 2023.

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 short-term and long-term, cancellable and occasionally non-cancellable, contracts with major 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 September 30, 2023, except as noted below.
On April 27, 2022, the Company entered into a purchase and sale agreement with a third-party manufacturer to purchase certain assets to design and manufacture fan wheels for the purchase price of $6.5 million. As of September 30, 2023, we have paid approximately $3.5 million related to this agreement, which is included in other long-term assets and property, plant and equipment, with the remaining $3.0 million included in accounts payable and other long-term assets on our consolidated balance sheets. The final payment was made on October 30, 2023.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the notes thereto, which are included in this report, and our audited consolidated financial statements and the notes thereto, which are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.
This discussion contains or incorporates by reference “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not historical facts, but rather are based on expectations, estimates, assumptions and projections about our industry, business and future financial results, based on information available at the time this report is filed with the SEC or, with respect to any document incorporated by reference, available at the time that such document was prepared. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those identified in the section entitled “Forward-Looking Statements” in this Item 2 of this Quarterly Report on Form 10-Q and in the section entitled “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. We do not assume any obligation to update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events, new information or circumstances or otherwise, except as required by law.
Overview
We engineer, manufacture, market, and sell premium air conditioning and heating equipment consisting of standard, 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 retail, manufacturing, educational, lodging, supermarket, data centers, medical and pharmaceutical, and other commercial industries. We market our products to all 50 states in the United States and certain provinces in Canada. Foreign sales were approximately $29.3 million of our total net sales for the nine months ended September 30, 2023 and $18.0 million of our sales during the same period of 2022.
Our business can be affected by a number of economic factors, including the level of economic activity in the markets in which we operate. Both the new construction and replacement markets are cyclical. If the domestic economy were to slow or enter a recession, this could result in a decrease in our sales volume and profitability. Sales in the commercial and industrial new construction markets generally lag 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, changes in market demand between more customized higher performing HVAC equipment and lower priced standard equipment, as well as many other factors.

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. Furthermore, 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 to a more concentrated customer base. A combination of our internal sales force and select group of independent sales representatives is most effective for BASX's products.
The principal components of cost of goods sold are labor, raw materials, component costs, factory overhead, freight 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 given that the market continues to be volatile and unpredictable as a result of the uncertainty related to the U.S. economy and global economy. At September 30, 2023, the price (year to date average) for copper, stainless steel and aluminum increased 1.2%, 5.0%, and 16.7%, respectively, as compared to the price (year to date average) at September 30, 2022, while the price (year to date average) for galvanized steel decreased 29.9% as compared to the price (year to date average) at September 30, 2022.
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 2022, we implemented two significant price increases as well as a recurring 1% monthly price increase effective June 1, 2022 through April 1, 2023.
Backlog
The following table shows our historical backlog levels:

September 30, 2023 |  | December 31, 2022 |  | September 30, 2022
(in thousands)
$ | 490,591 |  |  | $ | 548,022 |  |  | $ | 514,735 |

While our backlog is down at September 30, 2023 compared to December 31, 2022, our bookings remain strong. The year-ended December 31, 2022 was a record year for bookings and our backlog was swollen causing us to extend lead times. Investments made in our facilities and workforce have significantly improved our capacity and operational efficiencies. Production rates are at all time highs, trimming our backlog down to a more manageable size and allowing our lead times to improve.

The following are recent highlights and items that impacted our results of operations, cash flows and financial condition:
•Sales for the three and nine months ended September 30, 2023 grew 28.6% and 35.9%, respectively, due to record production rates and price increases realized during the period as compared to the same periods in the prior year.
•Our gross profit margin for the quarter ended September 30, 2023 of 37.2% increased 1,020 basis points from the quarter ended September 30, 2022 due to increased organic volumes for operational efficiencies and better overhead absorption.
•We completed the repurchase of $25.0 million of shares under our current share repurchase authorization.
We report our financial results based on three reportable segments: AAON Oklahoma, AAON Coil Products, and BASX, which are further described in "Segments" (Note 19) 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 income from operations. The CODM does not evaluate operating segments using asset or liability information.

2 Presented after intercompany eliminations. |

For the three months ended September 30, 2023 total net sales increased $69.4 million or 28.6%, with 16.7% of the increase coming from realization of price increases and the remaining 11.9% coming from increases in organic volume. AAON Coil Products had a smaller backlog and realized price increases quicker than AAON Oklahoma. This along with inefficiencies related to implementing a new production line of BASX product at AAON Coil Products lead to year over year decreases in sales for this segment.
Gross profit as a percent of sales increased to 37.2% for the three months ended September 30, 2023 as compared to 27.0% for the three months ended September 30, 2022. As noted above, realization of price increases has improved our margin profile along with the slowing of inflation. Additionally, most of the organic growth noted above comes from our AAON Oklahoma segment, significantly improving overhead absorption and margin performance. BASX has benefited from larger jobs as a result of the revenue synergies created by being part of AAON which allows them to have a higher production rate without increasing personnel.

As shown in the table below, we've experienced year over year increases in the cost of several raw materials. We implemented multiple price increases during 2022 and 2023 to counteract the increased cost of material. Some of the price increases have yet to be realized. Additionally, in order to retain our existing employees, we continue to award periodic raises in addition to our annual merit raises to our employees.

Selling, general and administrative expenses increased $22.6 million for the three months ended September 30, 2023 from the prior year period. Profit sharing increased $3.2 million or 85.7% due to our increased operating results. Depreciation and amortization has increased due to increased investments in back office technology and automation. Professional fees increased $8.6 million during the three months ended September 30, 2023 due the litigation settlement (Note 17). Other expenses increased $4.5 million or 109.0% during the three months ended September 30, 2023 due mostly to increased travel and consulting expenses.

The Company’s estimated annual 2023 effective tax rate, excluding discrete events, is expected to be approximately 24.1%.
During the quarter, we saw increases in our tax rate due to the finalization and filing of our 2022 tax return that resulted primarily from lower than expected federal research and development tax credit. This was offset by a decrease in our tax rate as a result of higher estimated income for the State of Oklahoma and thus higher realization of our investment credit.

For the nine months ended September 30, 2023 total net sales increased $227.7 million or 35.9%, with approximately 19.3% coming from realization of price increase and 16.6% coming from increases in organic volumes.
Gross profit as a percent of sales increased to 33.3% for the nine months ended September 30, 2023 as compared to 25.1% for the nine months ended September 30, 2022. Total gross profit increased mostly due to the multiple price increases realized for the nine months ended September 30, 2023 counteracting the increasing cost of materials and labor. The increase in overall unit production volume, resulted in favorable labor and overhead efficiencies, improving absorption of fixed costs.
AAON Coil Products' gross profit as a percent of sales decreased to 25.7% for the nine months ended September 30, 2023 as compared to 33.3% for the nine months ended September 30, 2022 mostly due to less than optimal overhead absorption as discussed above. Start-up of production related to BASX units being built at AAON Coil Products was slower than anticipated and resulted in lower volumes.
The cost of our material fluctuates month-to-month. We implemented multiple price increases during 2022 and 2023 to counteract the increased cost of material. Some of the price increases have yet to be realized. Additionally, in order to retain our existing employees, we continue to award periodic raises in addition to our annual merit raises to our employees. During the nine months ended September 30, 2023, our gross profit decreased by approximately $3.7 million for changes in our paid time off policies and for payroll taxes and 401(k) matching contributions related to profit sharing payments and stock transactions as our stock reached record highs consistently during the first quarter.

Professional fees increased $8.2 million during the three months ended September 30, 2023 due the litigation settlement (Note 17). Other expenses increased $8.6 million or 68.2% during the nine months ended September 30, 2023 due mostly to increased travel and closing costs related to the 2023 New Market Tax Credit (Note 16).
Income Taxes

Income tax provision |  | $ | 29,447 |  |  | $ | 17,286 |  |  | 18.4 | % |  | 21.9 | %

The Company’s estimated annual 2023 effective tax rate, excluding discrete events, is expected to be approximately 24.1%.
The decrease in the overall effective tax rate was primarily due to the change in our valuation allowance from the discontinuation of our participation in the state of Oklahoma’s manufacturing property investment program. This change will allow the Company to utilize existing credit carryforwards in future tax years, eliminating the need for a valuation allowance against this deferred tax asset. The related valuation allowance was reversed resulting in a one-time benefit of $3.1 million to the estimated income tax provision for the nine months ended September 30, 2023.
Additionally during the nine months ended September 30, 2023, the Company recorded an excess tax benefit of $6.3 million as compared to $1.3 million during the same period in 2022. The increase was primarily due to timing of stock option exercises as a result of our high stock price during the nine months ended September 30, 2023.

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 decreased $5.2 million from December 31, 2022 to September 30, 2023 and totaled $0.2 million at September 30, 2023. Our restricted cash increased $21.8 million from the closing of our recent New Markets Tax Credit related to our Longview, Texas Expansion. We expect most funds will be released from this account by the end of 2023. The funds will be used to pay down our revolving line of credit. We have also seen increases in our current income tax payable due to the tax law changes surrounding the capitalization of research and development costs. This has increased our cash paid for income taxes.
Revolving Line of Credit - Our revolving credit facility (as amended, "Revolver"), provides for maximum borrowings of $200.0 million. As of September 30, 2023 and December 31, 2022, we had $78.4 million and $71.0 million, respectively, outstanding under the Revolver. We had two standby letters of credit totaling $2.3 million as of September 30, 2023. At September 30, 2023, we have $119.3 million of borrowings available under the Revolver. The Revolver expires May 27, 2027. On April 20, 2023 we amended the Revolver to allow for the occurrence of transactions associated with the New Markets Tax Credit executed on April 25, 2023 (Note 16).
Any outstanding loans under the Revolver bear interest at the daily compounded secured overnight financing rate ("SOFR") plus the applicable margin. 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. The weighted average interest rate on borrowings outstanding on the Revolver was 6.5% and 6.3% for the three and nine months ended September 30, 2023. 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 nine months ended September 30, 2023 and 2022.
If SOFR cannot be determined pursuant to the definition, as defined by the Revolver 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%.
At September 30, 2023, 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 September 30, 2023, our leverage ratio was 0.33 to 1.0, which meets the requirement of not being above 3 to 1.
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 NMTC transaction, the Company received a $23.0 million NMTC allocation for the 2019 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 2019 NMTC transaction, the Company provided an aggregate of approximately $15.9 million to the Investor, in the form of a loan receivable, with a term of twenty-five years, bearing an interest rate of 1.0%. This $15.9 million in proceeds plus capital contributed from the 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.
2023 New Markets Tax Credit - On April 25, 2023, the Company entered into a transaction with a subsidiary of an unrelated third-party financial institution (the “2023 Investor”) and a certified Community Development Entity under a qualified New Markets Tax Credit (“2023 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 “2023 Project”). In connection with the 2023 NMTC transaction, the Company received a $23.0 million NMTC allocation for the 2023 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 2023 NMTC transaction, the Company provided an aggregate of approximately $16.7 million to the Investor, in the form of a loan receivable, with a term of twenty-five years, bearing an interest rate of 1.0%. This $16.7 million in proceeds plus capital contributed from the Investor was used to make an aggregate $23.8 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.

Stock Repurchases - The Board has authorized one active stock repurchase program for the Company. The Board must authorize the timing and amount of these purchases and all repurchases are in accordance with the rules and regulations of the SEC allowing the Company to repurchase shares from the open market. On November 3, 2022, the Board of Directors approved an updated stock repurchase plan with repurchases under the plan not to exceed $50 million. The current repurchase plan will expire at the Board of Directors' discretion.
Our open market repurchase programs are as follows:

Effective Date |  | Authorized Repurchase $ |  | Expiration Date
March 13, 2020 |  | $20 million |  | November 9, 2022

The Company repurchases shares of AAON, Inc. stock from employees for payment of statutory tax withholdings on stock transactions. All other repurchases from directors or employees are contingent upon Board approval. All repurchases are done at current market prices.
Lastly, the Company also had a stock repurchase arrangement by which employee-participants in our 401(k) savings and investment plan were entitled to have shares in AAON, Inc. stock in their accounts sold to the Company. The 401(k) Plan was amended in June 2022 to discontinue this program. No additional shares have been purchased by the Company under this arrangement since June 2022.

2 Reflects three-for-two stock split effective August 16, 2023.

On July 7, 2023, the Board of Directors declared a three-for-two stock split of the Company's common stock that was paid in the form of a stock dividend. Stockholders of record at the close of business on July 28, 2023 received one additional share for every two shares they held as of that date on August 16, 2023 (ex-dividend date August 17, 2023). All share and per share information has been updated to reflect the effects of this stock split.
Based on historical performance and current expectations, we believe our cash and cash equivalents balance, the projected cash flows generated from our operations, our existing committed revolving credit facility (or comparable financing) and our expected ability to access capital markets will satisfy our working capital needs, capital expenditures, and other liquidity requirements associated with our operations in 2023 and the foreseeable future.

Cash Flows Provided by 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. In early 2022, the Company began increasing 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. Increases in the timing of our customer prepayment as well as increases in our employee bonuses pools and benefits (as a result of our positive operating results) increased our cash provided by accrued liabilities.
Payment terms for BASX jobs typically require upfront cash to fund the job resulting in cash inflows related to our contract liabilities and cash inflows fluctuate due to job timing and scheduling.

We have also seen increases in our current income tax payable due to the tax law changes surrounding the capitalization of research and development costs. This has increased our cash paid for income taxes.
The increase in our accrued liabilities and other long-term liabilities is due litigation settlement (Note 17) accrued at September 30, 2023.
Cash Flows Used in Investing Activities
The capital expenditures for the nine months ended September 30, 2023 relate to our continued investment in our production capabilities. Purchases during the nine months ended September 30, 2023 relate to additional sheet metal and other machinery for both replacement and growth, additional production and warehouse space in Longview, Texas, additional office space in Tulsa, Oklahoma, additional land in Tulsa, Oklahoma for future growth, and a partial interest in an airplane. The capital expenditure program for 2023 is estimated to be approximately $100.0 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 Provided by Financing Activities
The change in cash from financing activities in 2023 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 increased operating results and financial condition.
Furthermore, cash flows from financing activities is historically affected by the timing of stock options exercised by our employees. Stock options exercised increased due to the increase in the number of employee options exercised and increase in our average stock price during the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.
Additionally, we repurchased approximately 402,873 shares for approximately $25.0 million during the nine months ended September 30, 2023 under our current stock repurchase program (Note 15).
Effective with the cash dividend declared on March 1, 2023 (paid on March 31, 2023), the Company moved from semi-annual cash dividends to quarterly cash dividends. The third quarter dividend was paid on September 29, 2023.
Commitments and Contractual Obligations
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 September 30, 2023 except as described below.
On April 27, 2022, the Company entered into a purchase and sale agreement with a third-party manufacturer to purchase certain assets to design and manufacture fan wheels for the purchase price of $6.5 million. As of September 30, 2023, we have paid approximately $3.5 million related to this agreement, which is included in other long-term assets and property, plant and equipment, with the remaining $3.0 million included in accounts payable and other long-term assets on our consolidated balance sheets. The final payment was made on October 30, 2023.
Critical Accounting Policies
There have been no material changes in the Company’s critical accounting policies during the nine months ended September 30, 2023.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Commodity Price Risk
We are exposed to volatility in the prices of commodities used in some of our products and we may use cancellable and non-cancellable contracts with our major suppliers for periods of six to 18 months to manage this exposure.

We are exposed to changes in interest rates related to our outstanding debt. As of September 30, 2023, we had an outstanding balance of $78.4 million.

Stock Repurchases
The Company may repurchase AAON, Inc. stock on the open market from time to time.

The Board must authorize the timing and amount of these purchases and all repurchases are in accordance with the rules and regulations of the SEC allowing the Company to repurchase shares from the open market.

The current repurchase plan will expire at the Board of Directors discretion.
The Company repurchases shares of AAON, Inc. stock from employees for payment of statutory tax withholdings on stock transactions. All other repurchases from directors or employees are contingent upon Board approval. All repurchases are done at current market prices. From inception through September 30, 2023, we repurchased approximately 3.1 million shares (at current market prices) for an aggregate price of $24.6 million, or an average price of $7.95 per share.

Lastly, the Company also had a stock repurchase arrangement by which employee-participants in our 401(k) Plan were entitled to have shares of AAON, Inc. stock in their accounts sold to the Company. The 401(k) Plan was amended in June 2022 to discontinue this program. From inception through September 30, 2023, we repurchased approximately 12.5 million shares (at current market prices) for an aggregate price of $171.8 million, or an average price of $13.78 per share.

Contingent Shares Issued in BASX Acquisition
In December 2021, we closed on the acquisition of BASX. Under the MIPA Agreement, we committed to $78.0 million in the aggregate of contingent consideration to the former owners of BASX, which is payable in approximately 1.56 million shares of the Company's common stock, par value $0.004 per share. The shares do not accrue dividends.
Under the MIPA Agreement, the potential future issuance of the shares is contingent upon BASX meeting certain post-closing earn-out milestones during each of the years ended 2021, 2022, and 2023. Based on the final allocation of the consideration paid, we estimated the fair value of contingent consideration related to these shares to be approximately $60.0 million, which is included in additional paid-in capital on the consolidated balance sheets. As of September 30, 2023, 0.58 million shares and 0.73 million shares related to the earn-out milestones for the years ended 2022 and 2021, respectively, have been issued to the former owners of BASX as private placements exempt from registration with the SEC under Rule 506(b), which are included in common stock on the consolidated statements of stockholders' equity.
