Notes to the Consolidated Financial Statements

(Unaudited)

1. General

Basis of Presentation

The accompanying unaudited consolidated financial statements of AAON, Inc., a Nevada corporation, and our operating subsidiaries, all of which are wholly-owned, (collectively, the “Company”) 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 two 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, 2019 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, 2019. All intercompany balances and transactions have been eliminated in consolidation.

We are engaged in the engineering, manufacturing, marketing and sale of air conditioning and heating equipment consisting of standard, semi-custom and custom rooftop units, chillers, 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 reserves, warranty accrual, worker's compensation accrual, medical insurance accrual, income taxes and share-based compensation. 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, 2019.

Fair Value Measurements

We adopted ASU No. 2018-13, Fair Value Measurements (Topic 820) , as amended, as of January 1, 2020. The ASU includes additional disclosure requirements for unrealized gains and losses for Level 3 fair value measurements and significant observable inputs used to develop Level 3 fair value measurements. There was not a material impact to financial statements upon adoption. 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:

- 5 -

• 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 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.

Intangible Assets

Our intangible assets include various trademarks, service marks and technical knowledge acquired in our February 2018 business combination. We amortize our 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.

Goodwill

Goodwill represents the excess of the consideration paid for the acquired businesses, in our February 2018 business combination, over the fair value of the individual assets acquired, net of liabilities assumed. Goodwill at March 31, 2020 is deductible for income tax purposes. Goodwill is not amortized, but instead is 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 below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto.

In December 2019, the FASB issued ASU 2019-12, Income Taxes: Simplifying the Accounting for Income Taxes . The ASU includes simplification of accounting for income taxes for franchise taxes, step up in tax basis for goodwill as part of a business combination and interim reporting of enacted changes in tax laws. The ASU is effective for the Company beginning after December 15, 2020. We do not expect ASU 2019-12 will have a material effect on our consolidated financial statements and notes thereto.

Outdoor Mechanical Rooms	915		482
Water Source Heat Pumps	3,703		5,844
Part Sales	6,513		6,490
Other	4,777		3,019
Net Sales	$	137,483	$	113,822

Disaggregated units sold by major source:


	Three months ended March 31,
	2020	2019
Rooftop Units	4,061	3,762
Condensing Units	408	394
Air Handlers	510	580
Outdoor Mechanical Rooms	10	11
Water Source Heat Pumps	1,617	2,289
Total Units	6,606	7,036

The Company recognizes revenue when it satisfies the performance obligation in its contracts. Most of the Company’s products are highly customized, cannot be resold to other customers and the cost of rework to be resold is not economical. The Company has a formal cancellation policy 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. For all other products that are part sales or standardized units, 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. Sales of our products are moderately seasonal with the peak period being July - November of each year.

In addition, the Company presents revenues net of sales tax and net of certain payments to 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. 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.

We are responsible for billings and collections resulting from all sales transactions, including those initiated by our Representatives. 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. 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. The Company is under no obligation related to Third Party Products.

- 7 -

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 $ 12.6 million and $ 11.5 million for the three months ended March 31, 2020 and 2019, respectively.

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.

3. Leases

We adopted ASU No. 2016-02, Leases (Topic 842) , as amended, as of January 1, 2019, using the transition method, which becomes effective upon the date of adoption. The transition method allows entities to initially apply the new leases standard at the adoption date (January 1, 2019) and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. We have also elected the short-term lease measurement and recognition exemption which does not require balance sheet presentation for short-term leases. The Company historically does not enter into numerous or material lease agreements to support its manufacturing operations. Furthermore, any lease agreements entered into are usually less than a year and for leases on non material assets such as warehouse vehicles and office equipment.

Adoption of the new standard resulted in the recording of additional lease right of use assets and lease liabilities of approximately $ 1.8 million as of January 1, 2019, which mostly relates to the multi-year facility lease assumed in our February 2018 business combination. The cumulative-effect adjustment to the opening balance was immaterial to the consolidated financial statements as a whole. The standard did not materially impact our consolidated net earnings or cash flows. As of March 31, 2020, our right of use assets and lease liabilities are approximately $ 1.6 million.

4. Accounts Receivable

Accounts receivable and the related allowance for doubtful accounts are as follows:


	March 31, 2020		December 31, 2019
	(in thousands)

5. Inventories

Inventories are valued at the lower of cost or net realizable value. Cost is determined by the first-in, first-out (“FIFO”) method. We establish an allowance for excess and obsolete inventories based on product line changes, the feasibility of substituting parts and the need for supply and replacement parts.

10. Revolving Credit Facility

Our revolving credit facility, as amended, ("BOK Revolver") provides for maximum borrowings of $ 30.0 million, which is provided by BOKF, NA dba Bank of Oklahoma (“Bank of Oklahoma”). Under the line of credit, there is one standby letter of credit totaling $ 1.7 million. Borrowings available under the revolving credit facility at March 31, 2020 were $ 28.3 million. Interest on borrowings is payable monthly at LIBOR plus 2.0 %. No fees are associated with the unused portion of the committed amount. We had no outstanding balance under the revolving credit facility at March 31, 2020 and December 31, 2019. The revolving credit facility expires on July 26, 2021.

As of March 31, 2020, we were in compliance with our financial covenants. These covenants require that we meet certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At March 31, 2020, our tangible net worth was $ 306.3 million and met the requirement of being at or above $ 175.0 million. Our total liabilities to tangible net worth ratio was 0.3 to 1, and met the requirement of not being above 2 to 1.

11. Income Taxes

The provision (benefit) for income taxes consists of the following:


	Three months ended
	March 31, 2020		March 31, 2019
	(in thousands)
Current	$	6,143	$	1,786
Deferred	( 167 )		909
	$	5,976	$	2,695

The provision for income taxes differs from the amount computed by applying the statutory federal 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
	March 31, 2020		March 31, 2019
Federal statutory rate	21.0	%	21.0	%
State income taxes, net of Federal benefit	5.2		6.1


Excess tax benefits	( 3.8 )		( 2.7 )

Other	( 0.9 )		( 0.9 )
Effective tax rate	21.5	%	23.5	%

The Company's estimated annual 2020 effective tax rate, excluding discrete events, is approximately 25 %. 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 2016 to present, and to non-U.S. income tax examinations for the tax years 2015 to present. In addition, we are subject to state and local income tax examinations for the tax years 2015 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.

Coronavirus Aid, Relief, and Economic Security Act

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted on March 27, 2020, and includes a retroactive correction to the 2017 Tax Cuts and Jobs Act that allows for much faster depreciation of qualified improvement property that is placed in service after December 31, 2017. The retroactive correction allows for 100 % first-year bonus depreciation for qualified improvement property placed in service in the tax years ended 2018 to 2022. Alternatively, companies can depreciate qualified improvement property placed in service during the tax year ended 2018 and beyond over 15 years using the straight-line method. Amending a prior period return to claim 100 % first-year bonus depreciation for qualified improvement property placed in service in those years could result in a net operating loss that can be carried back to a prior tax year to recover taxes paid in that prior year.

- 11 -

As the Company collects and prepares necessary data and interprets the CARES Act and any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, additional adjustments to the financial statements may be made. We don't expect these additional adjustments to materially impact the provision for income taxes and effective tax rate in the period in which the adjustments are made. We expect the final accounting for the tax effects of the CARES Act to be completed by the second quarter in 2020.

12. Share-Based Compensation

On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan (“LTIP”) which provided an additional 3.3 million shares that could be granted in the form of stock options, stock appreciation rights, restricted stock awards, performance units and performance awards, in addition to the shares from the previous plan, the 1992 Plan. Since inception of the LTIP, non-qualified stock options and restricted stock awards have been granted with a five years vesting schedule. 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 6.4 million shares, comprised of 3.4 million new shares provided for under the 2016 Plan, approximately 0.4 million shares that were available for issuance under the previous LTIP that are now authorized for issuance under the 2016 Plan, and an additional 2.6 million shares that were approved by the stockholders on May 15, 2018. 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 will determine the persons to whom awards are to be made, determine the type, size and terms of awards, interpret the 2016 Plan, establish and revise rules and regulations relating to the 2016 Plan and make any other determinations that it believes necessary for the administration of the 2016 Plan.

Options

The total pre-tax compensation cost related to unvested stock options not yet recognized as of March 31, 2020 is $ 28.3 million and is expected to be recognized over a weighted average period of 3.6 years.

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, 2020 and 2019 using a Black Scholes-Merton Model:


	Three months ended
	March 31, 2020	March 31, 2019
Directors and Officers:
Expected dividend rate	$ 0.32	$ 0.32
Expected volatility	31.08 %	29.54 %
Risk-free interest rate	0.70 %	2.40 %
Expected life (in years)	5.0	5.0
Employees:
Expected dividend rate	$ 0.32	$ 0.32
Expected volatility	31.07 %	29.54 %
Risk-free interest rate	0.71 %	2.40 %
Expected life (in years)	5.0	5.0

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.

Exercisable at March 31, 2020	1,024,276	$	32.73

The total intrinsic value of options exercised during the three months ended March 31, 2020 and 2019 was $ 3.9 million and $ 2.1 million, respectively. The cash received from options exercised during the three months ended March 31, 2020 and 2019 was $ 4.5 million and $ 4.0 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 March 31, 2020, unrecognized compensation cost related to unvested restricted stock awards was approximately $ 6.5 million, which is expected to be recognized over a weighted average period of 3.1 years.

- 13 -

A summary of the unvested restricted stock awards is as follows:


Restricted Stock	Shares	Weighted Average Grant Date Fair Value
Unvested at December 31, 2019	267,484	$	34.42
Granted	58,840	42.65
Vested	( 62,292 )	30.71
Forfeited	( 1,120 )	35.88

Share-Based Compensation

A summary of share-based compensation is as follows:


	Three months ended
	March 31, 2020		March 31, 2019
Grant date fair value of awards during the period:	(in thousands)
Options	$	10,905	$	19,944
Restricted stock	2,510		3,708
Total	$	13,415	$	23,652

Share-based compensation expense:
Options	$	1,632	$	4,622
Restricted stock	719		785
Total	$	2,351	$	5,407

Income tax benefit/(deficiency) related to share-based compensation:
Options	$	731	$	243
Restricted stock	334		151
Total	$	1,065	$	394

Share-based compensation expense is recognized on a straight-line basis over the service period of the related share-based compensation award. Stock options and restricted stock awards, granted to employees, vest at a rate of 20% per year. Restricted stock awards granted to directors historically vest 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. Forfeitures are accounted for as they occur.

Historically, if the employee or director is retirement eligible (as defined by the respective LTIP) or becomes retirement eligible during 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 share-based compensation 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.

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 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 three months ended March 31, 2020 and 2019.

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 Plan

We maintain a discretionary profit sharing bonus plan under which approximately 10 % of pre-tax profit is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible employees are regular full-time employees 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.

Participants are expected to pay a portion of the premium costs for coverage of the benefits provided under the Plan. We estimate our self-insurance liabilities using an analysis provided by our claims administrator and our historical claims experience. In addition, the Company matches 175 % of a participating employee's allowed contributions to a qualified health saving account to assist employees with our heath insurance plan deductibles.

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:

16. 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 “Investor”) and a certified Community Development Entity under a qualified New Markets Tax Credit (“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 “Project”). In connection with the 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 Project.

Upon closing of the 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 NMTCs.

- 17 -

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 Investor's interest of $ 6.3 million is recorded in New market tax credit obligation on the consolidated balance sheet. 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.

The Investor is subject to 100 percent recapture of the NMTC 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 NMTC arrangement. Noncompliance with applicable requirements could result in the Investor’s 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 this financing arrangement.

The 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 transaction in these VIEs outside of the financing transactions executed as part of the NMTC arrangement.

17. Commitments and Contingencies

We are subject to various claims and legal actions that arise in the ordinary course of business. 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 have concluded that the likelihood is remote that the ultimate resolution of any pending litigation or claims will be material or have a material adverse effect on the Company's business, financial position, results of operations and/or cash flows.

We are occasionally party to short-term, 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. At March 31, 2020, we had one material contractual purchase obligation for approximately $ 1.8 million that expires in December 2020.

18. Related Parties

The Company purchases some supplies from an entity controlled by the Company’s CEO. The Company sometimes makes sales to the CEO for parts. Additionally, the Company sells units to an entity owned by a member of the President's immediate family. This entity is also one of the Company’s Representatives and as such, the Company makes payments to the entity for third party products. All related party transactions are made on standard Company terms.

20. Error Correction

We have corrected herein our consolidated financial statements as of March 31, 2019 and for the three months ended March 31, 2019, in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 250, Accounting Changes and Error Corrections .

- 19 -

Error Correction Background

During the preparation of the 2019 Annual Report on Form 10-K (filed on February 27, 2020) the Company noted errors in previously issued financial statements relating to share-based compensation expense for stock options and restricted stock awards held by retirement eligible employees and directors. As defined by our Long-Term Incentive Plans (Note 12), stock options and restricted stock awards are fully vested when an active employee or director meets certain retirement eligibility requirements. We have corrected the previously issued 2019 financial statements to recognize all share-based compensation, related to retirement eligible employees or directors, by the earlier of the grant date (if retirement eligible on grant date) or ratably from grant date to retirement eligible date. The corrected financial statements also include corrections for the tax effect of the share-based compensation corrections as well as the corrections' impact on our prior periods' employees profit sharing bonus plan (Note 13).

Description of Tables

The following tables represent our corrected consolidated statements of income, statements of stockholders' equity, and statements of cash flows for the three months ended March 31, 2019, as well as our corrected consolidated balance sheet at March 31, 2019. The values as previously reported for March 31, 2019 were derived from our Quarterly Report on Form 10-Q for the three month ended March 31, 2019 filed on May 2, 2019.

21. Subsequent Event

In March 2020, the World Health Organization characterized the coronavirus ("COVID-19") a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The rapid spread of the pandemic and the continuously evolving responses to combat it have had an increasingly negative impact on the global economy. In view of the rapidly changing business environment, unprecedented market volatility and heightened degree of uncertainty resulting from COVID-19, we are currently unable to fully determine its future impact on our business. However, we are monitoring the progression of the pandemic and its potential effect on our financial position, results of operations and cash flows.

- 22 -

On April 22, 2020, our plant and office facilities in Tulsa, Oklahoma experienced hail related weather damage and we have filed a property insurance claim which carries a $ 500,000 deductible. We did not experience any operational interruption as a result of this weather event.

In May 2020, we entered into three material purchase agreements that total approximately $ 5.1 million. The purchase agreement periods are from September 2020 to January 2021.

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, 2019.

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, 2019. 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 and market air conditioning and heating equipment consisting of standard, semi-custom and custom rooftop units, chillers, 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, medical and other commercial industries. We market our products to all 50 states in the United States and all provinces in Canada. Foreign sales were approximately $2.8 million of our total net sales for the three months just ended and $4.2 million of our sales during the same period of 2019.

Our business can be affected by a number of economic factors, including the level of economic activity in the markets in which we operate. The uncertainty of the economy has negatively impacted the commercial and industrial new construction markets. A further decline in economic activity could result in a decrease in our sales volume and profitability. Sales in the commercial and industrial new construction markets correlate closely to the number of new homes and buildings that are built, which in turn is influenced by cyclical factors such as interest rates, inflation, consumer spending habits, employment rates and other macroeconomic factors over which we have no control.

We sell our products to property owners and contractors through a network of manufacturers’ representatives and our internal sales force. The demand for our products is influenced by national and regional economic and demographic factors. The commercial and industrial new construction market is subject to cyclical fluctuations in that it is generally tied to housing starts, but has a lag factor of six to 18 months. Housing starts, in turn, are affected by such factors as interest rates, the state of the economy, population growth and the relative age of the population. Our sales strategy is currently balanced between new construction and replacement applications. The new construction market in 2019 and through the first quarter of 2020 has been robust, but showing signs of uncertainty. Thus, we continue to emphasize promotion of the benefits of AAON equipment to property owners in the replacement market.

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 compressors, motors and electrical controls.

- 23 -

The price levels of most raw materials have started to decline in the past twelve months. We expect our raw material prices to remain stable. There is a possibility prices could rise in the future depending on the impact COVID-19 will have on our supply chain. For the three months ended March 31, 2020, the price (twelve month trailing average) for copper, galvanized steel, stainless steel and aluminum decreased 2.1%, 5.8%, 1.5% and 2.2%, respectively, as compared to the three months ended March 31, 2019.

We attempt to limit the impact of price fluctuations on these materials by entering into cancellable and non-cancellable fixed price contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw materials from our fixed price contracts for use in our manufacturing operations.

The following are recent highlights and items that impacted our results of operations, cash flows and financial condition:

• We continued to operate during the first quarter as an essential business with minimal disruption.

• Net sales were a record for the quarter, increasing by 20.8%.

• Our gross profit percentage improved from 22.3% in 2019 to 31.2%.

• We invested $21.9 million in capital expenditures, continuing our work on projects such as our Longview, TX expansion and additional Salvagnini machines that will increase our sheet metal capacity.

• Total cash, cash equivalents and restricted cash was $52.1 million at March 31, 2020.

• We shortened our lead times, improved deliveries to customers and reduced our backlog.

Gross profit	42,947		25,430		31.2	%	22.3	%

We continue to see overall raw material costs decrease. The Company has improved its labor and overhead efficiencies through increased production and absorption of fixed costs.

Profit sharing expenses increased due to our increased earnings for the period. Salaries & Benefits is up as well due in part to additional incentives for our employees as a result of the Company's good performance. Stock compensation is lower because the valuation of the Company wide equity grant done in March 2020 was less than the grant done in March 2019.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through net cash provided by operations and the occasional use of the revolving bank line of credit based on our current liquidity at the time.

Working Capital - Our unrestricted cash increased $8.9 million from December 31, 2019 to March 31, 2020 and totaled $35.7 million at March 31, 2020.

Revolving Line of Credit - Under the line of credit with Bank of Oklahoma, there was one standby letter of credit of $1.7 million as of March 31, 2020. At March 31, 2020, we have $28.3 million of borrowings available under the revolving credit facility. No fees are associated with the unused portion of the committed amount.

We had no outstanding balance under the revolving credit facility at March 31, 2020 and December 31, 2019. Interest on borrowings is payable monthly at LIBOR plus 2.0%. The termination date of the revolving credit facility is July 26, 2021.

At March 31, 2020, we were in compliance with all of the covenants under the revolving credit facility. We are obligated to comply with certain financial covenants under the revolving credit facility. These covenants require that we meet certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At March 31, 2020, our tangible net worth was $306.3 million, which meets the requirement of being at or above $175.0 million. Our total liabilities to tangible net worth ratio was 0.3 to 1.0 which meets the requirement of not being above 2 to 1.

New Market Tax Credit Obligation - On October 24, 2019, the Company entered into a transaction with a subsidiary of an unrelated third-party financial institution (the “Investor”) and a certified Community Development Entity under a qualified New Markets Tax Credit (“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 “Project”). In connection with the 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 expansion of its Longview, Texas facilities.

Upon closing of the 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 NMTCs.

Stock Repurchases - The Board has authorized three stock repurchase programs for the Company. The Company may purchase shares on the open market from time to time, up to a total of 5.7 million shares. 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:

² Expiration Date is at Board's discretion. The Company is authorized to effectuate repurchases of the Company's common stock on terms and conditions approved in advance by the Board.

Lastly, the Company repurchases shares of AAON, Inc. stock from certain of its directors and employees for payment of

- 26 -

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.

Our repurchase activity is as follows:

Total	13,797,694	$	221,833	$	16.08

Dividends - At the discretion of the Board, we pay semi-annual cash dividends. Board approval is required to determine the date of declaration and amount for each semi-annual dividend payment.

Our recent dividends are as follows:


Declaration Date	Record Date	Payment Date	Dividend per Share
May 20, 2019	June 3, 2019	July 1, 2019	$0.16
November 6, 2019	November 27, 2019	December 18, 2019	$0.16

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 2020 and the foreseeable future.

Cash Flows Provided by Operating Activities

The Company manages cash needs through working capital rather than drawing on its line of credit. Collections and payments cycles are on a normal pattern and fluctuate due to timing of payments and capital expenditure. Additionally, the Company has accrued for additional employee incentives based on the Company's favorable earnings to be paid after the Company's year-end audit is completed (Note 9).

Cash Flows Used in Investing Activities

The capital expenditure program for 2020 is estimated to be approximately $73.2 million. The capital expenditures for 2020 relate to the expansion of our Longview, Texas facility, additional Salvagnini sheet metal fabrication machines, completion of our R&D lab and other operational improvements. 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 Used in Financing Activities

Stock options exercised increased due to the increase in the number of employee options exercised and increases in our stock price. The Company also purchased approximately $5.0 million of our outstanding stock through the open market buyback program (Note 15 ) during the three months ended March 31, 2020.

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “will”, “should”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Important factors that could cause results to differ materially from those in the forward-looking statements include (1) the timing and extent of changes in raw material and component prices, (2) the effects of fluctuations in the commercial/industrial new construction market, (3) the timing and extent of changes in interest rates, as well as other competitive factors during the year, (4) general economic, market or business conditions, and (5) the impact of COVID-19 on the economy, demand for our products and our operations, including the measures taken by governmental authorities to address it, which may precipitate or exacerbate other risks and/or uncertainties.

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 fixed price cancellable and non-cancellable contracts with our major suppliers for periods of six to 18 months to manage this exposure.

Item 4. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer with the oversight of the Audit Committee, regarding the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded, as of the end of the period covered by this Quarterly Report, that our disclosure controls and procedures were effective.

(b) Previously Reported Material Weaknesses in Internal Control over Financial Reporting

As reported in our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2019, included in "Item 9A. Controls and Procedures" of Form 10-K for the year ended December 31, 2019, a material weakness existed in establishing the accounting policy for share-based compensation for retirement eligible employees.

Remediation Efforts in 2020

To remediate the material weakness described above and improve the operational effectiveness of our internal control over financial reporting, management increased the level of precision with which it reviews the Company's new accounting policies, ensuring to independently research items and conclusions as part of that review.

The Company plans to continue to improve its processes and controls through training and education. We have concluded that this material weakness was remediated as of March 31, 2020.

There have been no additional changes in internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

We are subject to various claims and legal actions that arise in the ordinary course of business. 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 have concluded that the likelihood is remote that the ultimate resolution of any pending litigation or claims will be material or have a material adverse effect on the Company's business, financial position, results of operations or cash flows.

Item 1A. Risk Factors.

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019. The risk factors described in our Annual Report could materially adversely affect our business, financial condition or future results. There have been no material changes to the risk factors included in our 2019 Annual Report, except as follows:

Our business, results of operations, financial condition, cash flows and stock price can be adversely affected by pandemics, epidemics or other public health emergencies, such as the recent outbreak of COVID-19 which has spread from China to many other countries including the United States. In March 2020, the World Health Organization characterized COVID-19 as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The outbreak has resulted in governments around the world implementing increasingly stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions, business curtailments, school closures,

and other measures. In addition, governments and central banks in several parts of the world have enacted fiscal and monetary stimulus measures to counteract the impacts of COVID-19.

We are considered a critical infrastructure industry, as defined by the U.S. Department of Homeland Security. Although we have continued to operate our facilities to date consistent with federal guidelines and state and local orders, the outbreak of COVID-19 and any preventive or protective actions taken by governmental authorities may have a material adverse effect on our operations, supply chain, customers and transportation networks, including business shutdowns or disruptions. The extent to which COVID-19 may adversely impact our business depends on future developments, which are highly uncertain and unpredictable, depending upon the severity and duration of the outbreak and the effectiveness of actions taken globally to contain or mitigate its effects. Any resulting financial impact cannot be estimated reasonably at this time, but may materially adversely affect our business, results of operations, financial condition and cash flows. Even after the COVID-19 pandemic has subsided, we may experience materially adverse impacts to our business due to any resulting economic recession or depression. Additionally, concerns over the economic impact of COVID-19 have caused extreme volatility in financial and other capital markets which has and may continue to adversely impact our stock price and our ability to access capital markets. To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in our 2019 Annual Report, such as those relating to our products and financial performance.

Item 2. Unregistered Sales of Equity and Securities and Use of Proceeds.

The Company may repurchase AAON, Inc. stock on the open market from time to time, up to a total of 5.7 million shares. We have repurchased a total of approximately 4.2 million shares (at current market prices) under the various open market stock buyback programs for an aggregate price of $74.8 million, or an average price of $17.79 per share. 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 July 1, 2005, we entered into a stock repurchase arrangement by which employee-participants in our 401(k) savings and investment plan are entitled to have shares of AAON, Inc. stock in their accounts sold to the Company. The maximum number of shares to be repurchased is contingent upon the number of shares sold by employees. From inception through March 31, 2020, we repurchased approximately 7.6 million shares (at current market prices) for an aggregate price of $126.5 million, or an average price of $16.66 per share.

Lastly, the Company repurchases shares of AAON, Inc. stock from certain of its directors and employees. The number of shares to be repurchased is contingent upon Board approval. From inception through March 31, 2020, we repurchased approximately 2.0 million shares (at current market prices) for an aggregate price of $20.5 million, or an average price of $10.26 per share.

Repurchases during the first quarter of 2020 were as follows:
