Notes to Condensed Consolidated Financial Statements

November 30, 2021

(Dollars in millions, except per share amounts)

Note 1 – Basis of Presentation

AAR CORP. and its subsidiaries are referred to herein collectively as “AAR,” “Company,” “we,” “us,” or “our,” unless the context indicates otherwise. The accompanying Condensed Consolidated Financial Statements include the accounts of AAR and its subsidiaries after elimination of intercompany accounts and transactions.

We have prepared these statements without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The Condensed Consolidated Balance Sheet as of May 31, 2021 has been derived from audited financial statements. To prepare the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”), management has made a number of estimates and assumptions relating to the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Certain information and note disclosures, normally included in comprehensive financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to such rules and regulations of the SEC. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021.

In the opinion of management, the Condensed Consolidated Financial Statements reflect all adjustments (which consist only of normal recurring adjustments) necessary to present fairly the Condensed Consolidated Balance Sheet of AAR CORP. and its subsidiaries as of November 30, 2021, the Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Comprehensive Income (Loss) for the three- and six-month periods ended November 30, 2021 and 2020, the Condensed Consolidated Statements of Cash Flows for the six-month periods ended November 30, 2021 and 2020, and the Condensed Consolidated Statement of Changes in Equity for the three- and six-month periods ended November 30, 2021 and 2020. The results of operations for such interim periods are not necessarily indicative of the results for the full year.

Note 2 – Discontinued Operations

During the third quarter of fiscal 2018, we decided to pursue the sale of our Contractor-Owned, Contractor-Operated (“COCO”) business previously included in our Expeditionary Services segment. Due to this strategic shift, the assets, liabilities, and results of operations of our COCO business have been reported as discontinued operations for all periods presented. Unless otherwise noted, amounts and disclosures throughout these Notes to Condensed Consolidated Financial Statements relate to our continuing operations.

In the fourth quarter of fiscal 2020, we completed the sale of the last operating contract of the COCO business shortly after government approval. Our continuing involvement in the COCO business is limited to the lease of certain aircraft which is an obligation of the acquirer of this contract. The assets and liabilities of our discontinued operations are primarily comprised of right-of-use assets and lease-related liabilities.

Note 3 – Sale of Composites Business

On August 31, 2020, we completed the sale of our aerostructures and aerospace products operations located in Clearwater, Florida and Sacramento, California (“Composites”). The Composites business was formerly included in our Expeditionary Services segment.

We recognized a loss on the sale of the Composites business of $19.5 million in the first quarter of fiscal 2021. In the fourth quarter of fiscal 2021, the post-closing working capital adjustment was finalized resulting in an additional loss of $0.7 million. The sale also included contingent consideration of up to $6.5 million based on the achievement of sales targets over a three-year period subsequent to the sale. Sales forecasts for the Composites business now indicate that it is unlikely that the sales targets will be achieved. We recognized a charge of $1.3 million in the three-month period ended November 30, 2021 to reflect the fair value of the contingent consideration at zero.

Note 4 – Revenue Recognition

Revenue is measured based on the consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer.

Our unit of accounting for revenue recognition is a performance obligation included in our customer contracts. A performance obligation reflects the distinct good or service that we must transfer to a customer. At contract inception, we evaluate if the contract should be accounted for as a single performance obligation or if the contract contains multiple performance obligations. In some cases, our contract with the customer is considered one performance obligation as it includes factors such as the good or service being provided is significantly integrated with other promises in the contract, the service provided significantly modifies or customizes another good or service or the good or service is highly interdependent or interrelated. If the contract has more than one performance obligation, we determine the standalone price of each distinct good or service underlying each performance obligation and allocate the transaction price based on their relative standalone selling prices.

The transaction price of a contract, which can include both fixed and variable amounts, is allocated to each performance obligation identified. Some contracts contain variable consideration, which could include incremental fees or penalty provisions related to performance. Variable consideration that can be reasonably estimated based on current assumptions and historical information is included in the transaction price at the inception of the contract but limited to the amount that is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Variable consideration that cannot be reasonably estimated is recorded when known.

Our performance obligations are satisfied over time as work progresses or at a point in time based on transfer of control of products and services to our customers. The majority of our sales from products are recognized at a point in time upon transfer of control to the customer, which generally occurs upon shipment. In connection with certain sales of products, we also provide logistics services, which include inventory management, replenishment, and other related services. The price of such services is generally included in the price of the products delivered to the customer, and revenues are recognized upon delivery of the product, at which point the customer has obtained control of the product. We do not account for these services separate from the related product sales as the services are inputs required to fulfill part orders received from customers.

For our performance obligations that are satisfied over time, we measure progress in a manner that depicts the performance of transferring control to the customer. As such, we utilize the input method of cost-to-cost to recognize revenue over time as this depicts when control of the promised goods or services is transferred to the customer. Revenue is recognized based on the relationship of actual costs incurred to date to the estimated total cost at completion of the performance obligation. We are required to make certain judgments and estimates, including estimated revenues and costs, as well as inflation and the overall profitability of the arrangement. Key assumptions involved include future labor costs and efficiencies, overhead costs, and ultimate timing of product delivery. Differences may occur between the judgments and estimates made by management and actual program results. For contracts that are deemed to be loss contracts, we establish forward loss reserves for total estimated costs that are in excess of total estimated consideration in the period in which they become known.

When contracts are modified, we consider whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original goods or services provided, are accounted for as if they were part of that existing contract with the effect of the contract modification recognized as an adjustment to revenue on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting. These changes are primarily adjustments to the estimated profitability for our long-term programs where we provide component inventory management and/or repair services.

(Dollars in millions, except per share amounts)

For the three-month period ended November 30, 2021, we recognized favorable and (unfavorable) cumulative catch-up adjustments of $8.2 million and $(2.3) million, respectively. For the three-month period ended November 30, 2020, we recognized favorable cumulative catch-up adjustments of $2.5 million. When considering these adjustments on a net basis, we recognized net favorable adjustments of $5.9 million and $2.5 million in the three-month periods ended November 30, 2021 and 2020, respectively.

For the six-month period ended November 30, 2021, we recognized favorable and (unfavorable) cumulative catch-up adjustments of $8.2 million and $(3.3) million, respectively. For the six-month period ended November 30, 2020, we recognized favorable cumulative catch-up adjustments of $2.8 million. When considering these adjustments on a net basis, we recognized net favorable adjustments of $4.9 million and $2.8 million in the six-month periods ended November 30, 2021 and 2020, respectively.

Under most of our U.S. government contracts, if the contract is terminated for convenience, we are entitled to payment for items delivered and fair compensation for work performed, the costs of settling and paying other claims, and a reasonable profit on the costs incurred or committed.

We have elected to use certain practical expedients permitted under ASU No. 2014-09, Revenue from Contracts with Customers. Shipping and handling fees and costs incurred associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in Cost of sales on our Condensed Consolidated Statements of Operations, and are not considered a performance obligation to our customers. Our reported sales on our Condensed Consolidated Statements of Operations are net of any sales or related non-income taxes. We also utilize the “as invoiced” practical expedient in certain cases where performance obligations are satisfied over time and the invoiced amount corresponds directly with the value we are providing to the customer.

Contract Assets and Liabilities

The timing of revenue recognition, customer billings, and cash collections results in a contract asset or contract liability at the end of each reporting period. Contract assets consist of costs incurred where revenue recognized over time using the cost-to-cost model exceeds the amounts billed to customers. Contract liabilities include advance payments and billings in excess of revenue recognized. Certain customers make advance payments prior to the satisfaction of our performance obligations on the contract. These amounts are recorded as contract liabilities until such performance obligations are satisfied, either over time as costs are incurred or at a point in time when deliveries are made. Contract assets and contract liabilities are determined on a contract-by-contract basis.

Net contract assets and liabilities are as follows:

	November 30,		May 31,
	2021		2021		Change
Contract assets – current	$	68.5	$	71.9	$	(3.4)
Contract assets – non-current		24.0		21.6		2.4
Contract liabilities:
Deferred revenue – current		(33.6)		(25.9)		(7.7)
Deferred revenue on long-term contracts		(9.1)		(5.4)		(3.7)
Net contract assets	$	49.8	$	62.2	$	(12.4)

Contract assets – non-current is reported within Other non-current assets and Deferred revenue on long-term contracts is reported within Other liabilities on our Condensed Consolidated Balance Sheets. Changes in contract assets and contract liabilities primarily result from the timing difference between our performance of services and payments from customers.

During the three-month period ended August 31, 2020, we terminated a commercial power-by-the-hour (“PBH”) customer contract which resulted in a charge of $2.2 million.

One of our PBH customers notified us in June 2021 that the customer would terminate its contract with us earlier than we originally anticipated. In conjunction with the early termination, we recognized a charge of $5.2 million in the three-month period ended

August 31, 2021, which included a reduction in contract assets and revenue of $1.0 million and the establishment of loss reserves of $4.2 million. As of November 30, 2021, our Condensed Consolidated Balance Sheet included remaining forward loss reserves of $2.2 million classified in Accrued liabilities.

During fiscal 2020, we established forward loss reserves for a certain PBH contract where total estimated costs are in excess of the total estimated consideration over the remainder of the contract. As of November 30, 2021, our Condensed Consolidated Balance Sheet included remaining forward loss reserves of $1.7 million classified in Accrued liabilities.

To support our PBH customer contracts, we previously entered into an agreement with a component repair facility to outsource a portion of the component repair and overhaul services. The agreement included certain minimum repair volume guarantees, which we have not met due to the impact of COVID-19 on commercial passenger aircraft flight hours. During fiscal 2021, we recognized a $4.5 million charge to reflect our estimated obligation over the remainder of the agreement for not achieving the minimum volume guarantees. During the three-month period ended August 31, 2021, we recognized a $1.7 million charge to increase the obligation reflecting the revised estimated shortfall on the minimum volume guarantee. As of November 30, 2021, our Condensed Consolidated Balance Sheet included remaining loss reserves of $4.6 million with $1.5 million classified as current in Accrued liabilities and $3.1 million classified as long-term in Other liabilities.

Changes in our deferred revenue were as follows for the three- and six-month periods ended November 30, 2021 and 2020:

	Three Months Ended				Six Months Ended
	November 30,				November 30,
	2021		2020		2021		2020

Deferred revenue at end of period	$	(42.7)	$	(48.4)	$	(42.7)	$	(48.4)

Remaining Performance Obligations

As of November 30, 2021, we had approximately $780 million of remaining performance obligations, also referred to as firm backlog, which excludes unexercised contract options and potential orders under our indefinite-delivery, indefinite-quantity (IDIQ) contracts. We expect that approximately 50% of this backlog will be recognized as revenue over the next 12 months with approximately 40% of the remainder recognized over the next three years. The amount of remaining performance obligations that are expected to be recognized as revenue beyond 12 months, primarily relates to our long-term programs where we provide component inventory management and/or repair services.

Note 6 – Restructuring and Impairment Costs

During the six-month period ended November 30, 2020, we incurred severance and furlough-related costs of $8.2 million, which were included as a component of Cost of sales and Selling, general and administrative on our Condensed Consolidated Statements of Operations.

In accordance with ASC 360, Property, Plant and Equipment, we are required to test for impairment of long-lived assets whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable from its undiscounted cash flows. We utilize certain assumptions to estimate future undiscounted cash flows, including demand for our services, future market conditions and trends, business development pipeline of opportunities, current and future lease rates, lease terms, and residual values.

In light of declines in commercial airline volumes and commercial program contract terminations in fiscal 2020 and 2021, we evaluated future cash flows related to certain rotable assets supporting long-term programs and recognized asset impairment charges of $5.8 million in the three-month period ended August 31, 2020.

In conjunction with the early termination notice we received in June 2021 from one of our PBH customers, we evaluated future cash flows related to the rotable assets supporting that fleet type and recognized asset impairment charges of $2.3 million in the three-month period ended August 31, 2021.

Note 7 – Accounting for Stock-Based Compensation

Restricted Stock

In the three-month period ended August 31, 2021, as part of our annual long-term stock incentive compensation, we granted 43,010 shares of performance-based restricted stock and 50,845 shares of time-based restricted stock to eligible employees. The grant date fair value per share for these shares was $37.74 (the closing price on the grant date). We also granted 32,307 shares of time-based restricted stock to members of the Board of Directors with a grant date fair value per share of $42.56 (the closing price on the grant date).

Expense charged to operations for restricted stock during each of the three-month periods ended November 30, 2021 and 2020 was $0.8 million and $0.8 million, respectively, and $2.7 million and $2.7 million during the six-month periods ended November 30, 2021 and 2020, respectively.

Stock Options

In July 2021, as part of our annual long-term stock incentive compensation, we granted 143,745 stock options to eligible employees at an exercise price of $37.74 and grant date fair value of $13.36. The fair value of stock options was estimated using the Black-Scholes option pricing model with the following assumptions:

Risk-free interest rate	0.8	%
Expected volatility of common stock	41.6	%
Dividend yield	0.8	%
Expected option term in years	5.3

The total intrinsic value of stock options exercised during the six-month periods ended November 30, 2021 and 2020 was $0.1 million and $0.1 million, respectively. Expense charged to operations for stock options during the three-month periods ended November 30, 2021 and 2020 was $0.9 million and $1.0 million, respectively, and during the six-month periods ended November 30, 2021 and 2020 was $2.1 million and $1.8 million, respectively.

Note 10 – Sale of Receivables

On February 23, 2018, we entered into a Purchase Agreement with Citibank N.A. (“Purchaser”) for the sale, from time to time, of certain accounts receivable due from certain customers (the “Purchase Agreement”). Under the Purchase Agreement, the maximum amount of receivables sold is limited to $150 million and Purchaser may, but is not required to, purchase the eligible receivables we offer to sell. The term of the Purchase Agreement runs through February 22, 2022, however, the Purchase Agreement may also be terminated earlier under certain circumstances. The term of the Purchase Agreement shall be automatically extended for annual terms unless either party provides advance notice that they do not intend to extend the term.

We have no retained interests in the sold receivables, other than limited recourse obligations in certain circumstances, and only perform collection and administrative functions for the Purchaser. We account for these receivable transfers as sales under ASC 860, Transfers and Servicing, and de-recognize the sold receivables from our Condensed Consolidated Balance Sheet.

During the six-month periods ended November 30, 2021 and 2020, we sold $158.4 million and $243.1 million, respectively, of receivables under the Purchase Agreement and remitted $176.8 million and $268.5 million, respectively, to the Purchaser on their behalf. As of November 30, 2021 and May 31, 2021, we had collected cash of $3.7 million and $8.4 million, respectively, which was not yet remitted to the Purchaser as of those dates and was classified as Restricted cash on our Condensed Consolidated Balance Sheets.

We recognize discounts on the sale of our receivables and other fees related to the Purchase Agreement in Other expense, net on our Condensed Consolidated Statements of Operations. We incurred discounts on the sale of our receivables of $0 million and $0.1 million during the three-month periods ended November 30, 2021 and 2020, respectively, and $0.1 million and $0.2 million during the six-month periods ended November 30, 2021 and 2020, respectively.

Note 11 – Government Subsidies

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in the U.S. in response to the COVID-19 pandemic. The CARES Act includes provisions relating to refundable payroll tax credits, deferral of the employer portion of certain payroll taxes, net operating loss carrybacks, and other areas. The payroll tax deferral requires that the deferred payroll taxes be paid over two years, with half of the amount required to be paid by December 31, 2021 and the other half by December 31, 2022. As of November 30, 2021, we have deferred payroll taxes of $12.4 million of which $6.2 million are included in Accrued liabilities and $6.2 million in Other liabilities on our Condensed Consolidated Balance Sheet.

During the three-month period ended August 31, 2020, we received $57.2 million from the U.S. Treasury Department through the Payroll Support Program under the CARES Act. This funding included a $48.5 million cash grant which is to be used exclusively for the continuation of payment of employee wages, salaries and benefits for employees of certain maintenance, repair, and overhaul (“MRO”) facilities. The grant was recognized as contra-expense on our Condensed Consolidated Statement of Operations as the eligible wages, salaries and benefits were incurred. In fiscal 2021, we recognized the full amount of the grant as contra-expense within Cost of sales and Selling, general and administrative expenses of $47.5 million and $1.0 million, respectively.

The remaining funding of $8.7 million was a low interest 10-year senior unsecured promissory note (“Promissory Note”) which included interest at a rate per annum equal to the sum of (i) 1.0% for the first five years, and the applicable secured overnight financing rate plus 2.0% in years six through ten plus (ii) in kind interest of 3.0% for the first five years and increasing by 1.0% each year over the remaining term. The Promissory Note was pre-payable at par at any time and we re-paid the Promissory Note in full during the fourth quarter of fiscal 2021.  Certain corporate restrictions continue to apply to us which include restrictions on employee compensation.  The restrictions previously applicable to us relating to dividends, stock repurchases, and certain workforce actions have lapsed.

Other countries have enacted legislation similar to the CARES Act to provide relief and stimulus measures to assist companies in mitigating the financial impact from COVID-19 and supporting their employees. Our foreign subsidiaries recognized subsidies of $2.5 million and $1.6 million during the three-months ended November 30, 2021 and 2020, respectively, and $2.8 million and $4.9 million during the six-months ended November 30, 2021 and 2020, respectively, from foreign governments which have been deducted from the related expenses on our Condensed Consolidated Statements of Operations.

Note 12 – Financing Arrangements

A summary of the carrying amount of our debt is as follows:

	November 30,		May 31,
	2021		2021
Revolving Credit Facility expiring September 25, 2024 with interest payable monthly	$	104.5	$	109.5

Total debt		104.5		135.2
Debt issuance costs, net		(1.3)		(1.5)
Long-term debt	$	103.2	$	133.7

At November 30, 2021, our debt had a fair value that approximates its carrying value and is classified as Level 2 in the fair value hierarchy.

On October 18, 2017, we entered into a Credit Agreement with the Canadian Imperial Bank of Commerce, as lender (the “Credit Agreement”). The Credit Agreement provided a Canadian $31 million term loan with the proceeds used to fund the acquisition of two MRO facilities in Canada from Premier Aviation. The term loan was paid in full at the expiration of the Credit Agreement on November 1, 2021.

We maintain a Revolving Credit Facility with various financial institutions, as lenders, and Bank of America, N.A., as administrative agent for the lenders, which provides the Company an aggregate revolving credit commitment of $600 million and matures September 25, 2024. Under certain circumstances, we have the ability to request, but our lenders are not required to grant, an increase to the revolving credit commitment by an aggregate amount of up to $300 million, not to exceed $900 million in total. Borrowings under the Revolving Credit Facility bear interest at the offered Eurodollar Rate plus 87.5 to 175 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 0 to 75 basis points based on certain financial measurements if a Base Rate loan.

Borrowings outstanding under the Revolving Credit Facility at November 30, 2021 were $104.5 million and there were approximately $12.1 million of outstanding letters of credit, which reduced the availability of this facility to $483.4 million.

Our financing arrangements also require us to comply with leverage and interest coverage ratios, maintain a minimum net working capital level, and comply with certain affirmative and negative covenants, including those relating to financial reporting and notification, payment of indebtedness, cash dividends, taxes and other obligations, compliance with applicable laws, and limitations on additional liens, indebtedness, acquisitions, investments and disposition of assets. The Revolving Credit Facility also requires our significant domestic subsidiaries, and any subsidiaries that guarantee our other indebtedness, to provide a guarantee of payment under the Revolving Credit Facility. At November 30, 2021, we were in compliance with the financial and other covenants in our financing agreements.

Note 13 – Other Non-current Assets

Investments in Joint Ventures

Our investments in joint ventures include $10.7 million for our 40% ownership interest in a joint venture in India to develop and operate an airframe maintenance facility. The facility received certain regulatory approvals and commenced airframe maintenance operations in the second quarter of fiscal 2022.

The investment balance as of November 30, 2021 includes $9.4 million related to the guarantee liability recognized in conjunction with our guarantee of 40% of the Indian joint venture’s debt. The Indian joint venture is accounted for using the equity method. In addition, each of the partners in the Indian joint venture has a loan to the joint venture proportionate to its equity ownership. Our loan to the Indian joint venture under this arrangement was $3.1 million as of November 30, 2021.

License Fees

In June 2011, we entered into a ten-year agreement with Unison Industries (“Unison”) to be the exclusive worldwide aftermarket distributor for Unison’s electrical components, sensors, switches and other systems for aircraft and industrial uses. In June 2020, we entered into an extension and expansion of our agreement with Unison including a new termination date of December 31, 2031, an initial $25.0 million license fee paid in June 2020 to Unison, and annual license fees at a fixed percentage of our net sales of Unison products. The June 2020 payment of $25.0 million was capitalized and is being amortized on a straight-line basis over the term of the new agreement.

Split-Dollar Life Insurance Arrangements

We previously entered into split-dollar life insurance agreements to benefit certain former executives and officers. Under the terms of the arrangements, we made premium payments on the individuals’ behalf, and we retained a collateral interest in the policies generally to the extent of the premiums we previously paid.

(Dollars in millions, except per share amounts)

During the second quarter of fiscal 2021, certain split-dollar life insurance agreements were terminated and we received $12.0 million for reimbursement of both the life insurance premiums we previously paid and a portion of our prior tax payments made on the individuals’ behalf related to their imputed income on the policies. The reimbursement of the premiums paid of $10.0 million has been classified as cash flow from investing activities with the remainder included in cash flow from operating activities as it represents the reimbursement of a portion of the taxes previously paid and expensed. In the second quarter of fiscal 2021, we recognized a benefit of $1.3 million in Selling, general and administrative expenses on the Condensed Consolidated Statement of Operations for the net recovery of the taxes previously paid on behalf of the individuals.

Note 14 – Earnings per Share

The computation of basic earnings per share is based on the weighted average number of common shares outstanding during each period. The computation of diluted earnings per share is based on the weighted average number of common shares outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options and shares issuable upon vesting of restricted stock awards.

In accordance with ASC 260-10-45, Share-Based Payment Arrangements and Participating Securities and the Two-Class Method, our unvested restricted stock awards are deemed participating securities since these shares are entitled to participate in dividends declared on common shares. During periods of net income, the calculation of earnings per share for common stock excludes income attributable to unvested restricted stock awards from the numerator and excludes the dilutive impact of those shares from the denominator. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company.

Note 16 – Business Segment Information

Consistent with how our chief operating decision making officer (our Chief Executive Officer) evaluates performance and the way we are organized internally, we report our activities in two reportable segments: Aviation Services comprised of supply chain and MRO activities and Expeditionary Services comprised of manufacturing activities.

The Aviation Services segment consists of aftermarket support and services offerings that provide spare parts and maintenance support for aircraft operated by our commercial and government/defense customers. Sales in the Aviation Services segment are derived from the sale and lease of a wide variety of new, overhauled and repaired engine and airframe parts and components to the commercial aviation and government and defense markets. We provide customized inventory supply chain management, performance-based logistics programs, customer fleet management and operations, and aircraft component repair management services. The segment also includes repair, maintenance and overhaul of aircraft, landing gear and components. Cost of sales consists principally of the cost of product, direct labor, and overhead.

(Dollars in millions, except per share amounts)

The Expeditionary Services segment consists of primarily manufacturing operations with sales derived from the design and manufacture of pallets, shelters, and containers used to support the U.S. military’s requirements for a mobile and agile force, including engineering, design, and system integration services for specialized command and control systems. Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual Report on Form 10-K for the fiscal year ended May 31, 2021.

Our chief operating decision making officer (our Chief Executive Officer) evaluates performance based on our segments and utilizes gross profit as a primary profitability measure. Gross profit is calculated by subtracting cost of sales from sales. The assets and certain expenses related to corporate activities are not allocated to the segments.

Selected financial information for each segment is as follows:

AAR CORP. and Subsidiaries

Notes to Condensed Consolidated Financial Statements

November 30, 2021

(Unaudited)

(Dollars in millions, except per share amounts)

Department of Justice Investigation

As previously reported, the U.S. Department of Justice (“DoJ”), acting through the U.S. Attorney’s Office for the Southern District of Illinois, conducted an investigation of AAR Airlift Group, Inc. (“Airlift”), a wholly-owned subsidiary of AAR CORP., under the federal civil False Claims Act (“FCA”). The investigation related to Airlift’s performance of several contracts awarded by the U.S. Transportation Command (“TRANSCOM”) concerning the operations and maintenance of rotary-wing and fixed-wing aircraft in Afghanistan and Africa, as well as several U.S. Navy contracts. In June 2018, the DoJ informed Airlift that part of the investigation was precipitated by a lawsuit filed under the qui tam provisions of the FCA by a former employee of Airlift.

In June 2021, Airlift and the DoJ reached an agreement to settle the FCA investigation and related matters for approximately $11.5 million which concluded the DoJ investigation into Airlift’s contracts with TRANSCOM and the U.S. Navy. As part of the settlement, Airlift and AAR did not admit any wrongdoing.

We recognized charges of $11.0 million in discontinued operations in fiscal 2021 related to this agreement and related matters. As of May 31, 2021, our reserve was $12.7 million and payment for the entire matter was made in the first quarter of fiscal 2022.

Self-Reporting of Potential Foreign Corrupt Practices Act Violations

The Company retained outside counsel to investigate possible violations of the Company’s Code of Conduct, the U.S. Foreign Corrupt Practices Act, and other applicable laws, relating to the Company’s activities in Nepal and South Africa. Based on these investigations, in fiscal 2019, we self-reported these matters to the DoJ, the U.S. Securities and Exchange Commission and the UK Serious Fraud Office. The Company is fully cooperating with the reviews by these agencies, although we are unable at this time to predict what action, if any, they may take.

Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations (Dollars in millions)

General Overview

We report our activities in two reportable segments: Aviation Services comprised of supply chain and maintenance, repair, and overhaul (“MRO”) activities and Expeditionary Services comprised of manufacturing activities.

The Aviation Services segment consists of aftermarket support and services offerings that provide spare parts and maintenance support for aircraft operated by our commercial and government/defense customers. Sales in the Aviation Services segment are derived from the sale and lease of a wide variety of new, overhauled and repaired engine and airframe parts and components to the commercial aviation and government and defense markets. We provide customized inventory supply chain management, performance-based logistics programs, customer fleet management and operations, and aircraft component repair management services. The segment also includes repair, maintenance and overhaul of aircraft, landing gear and components. Cost of sales consists principally of the cost of product, direct labor, and overhead.

The Expeditionary Services segment consists of primarily manufacturing operations with sales derived from the design and manufacture of pallets, shelters, and containers used to support the U.S. military’s requirements for a mobile and agile force including engineering, design, and system integration services for specialized command and control systems. Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

Our chief operating decision making officer (our Chief Executive Officer) evaluates performance based on our segments and utilizes gross profit as a primary profitability measure. Gross profit is calculated by subtracting cost of sales from sales. The assets and certain expenses related to corporate activities are not allocated to the segments.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021.

Business Trends and Outlook

Consolidated sales for the second quarter of fiscal 2022 increased $33.0 million or 8.2% over the prior year quarter primarily due to an increase in sales of $34.3 million or 8.9% in our Aviation Services segment. Consolidated sales to commercial customers increased $63.5 million or 32.7% over the prior year quarter due to the partial recovery in commercial passenger air traffic. Our consolidated sales to government customers decreased $30.5 million or 14.6% primarily due to less volume across certain U.S. Government contracts.

Over the long-term, we expect to see strength in our Aviation Services segment given its offerings of value-added services to both commercial and government and defense customers. We believe long-term commercial and government growth trends are favorable. As we continue to experience recovery and growth in our operations, our long-term strategy continues to emphasize investing in the business and capitalizing on opportunities in those markets.

Both our commercial and government businesses are subject to the economic environment, impact of COVID-19, public policy decisions or other factors that could adversely impact our business, financial condition or results of operations in the future. A recent example of this was the U.S. Government’s decision to withdraw all U.S. Department of State personnel presence in Afghanistan. In conjunction with the U.S. exit from Afghanistan, we concluded our activities in country under our WASS and U.S. Department of Defense contracts. The operations related to our activities in Afghanistan contributed revenue of $67 million in fiscal 2021.

Three Month Period Ended November 30, 2021

Aviation Services Segment

Sales in the Aviation Services segment increased $34.3 million or 8.9% over the prior year period due to a $64.8 million or 33.7% increase in sales to commercial customers. The increase in sales to commercial customers was attributable to increased sales of $21.7 million in our MRO activities as commercial passenger air traffic continues to recover from the impact of COVID-19.  In addition, sales increased $15.8 million in our aftermarket parts trading activities which included whole asset sales of $12.0 million during the second quarter of fiscal 2022 compared to none in the prior year.

During the second quarter of fiscal 2022, sales in this segment to government and defense customers decreased $30.5 million or 15.8%, from the prior year period. The prior year quarter included sales of $19.7 million related to the installation of engines on the C-40 aircraft we are delivering to the Naval Air Systems Command in support of the U.S. Marine Corps. No engine installation activities occurred in the second quarter of fiscal 2022.

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting. In the second quarter of fiscal 2022, we had net favorable cumulative catch-up adjustments of $5.9 million compared to net favorable cumulative catch-up adjustments of $2.5 million in prior year quarter.  These adjustments primarily relate to our long-term, power-by-the-hour programs where we provide component inventory management and repair services as well as certain long-term government programs.

24

Cost of sales in Aviation Services increased $27.1 million, or 8.5%, over the prior year period which was in line with the sales increase discussed above.  

Gross profit in the Aviation Services segment increased $7.2 million, or 10.8%, over the prior year period. Gross profit on sales to commercial customers increased $6.7 million, or 17.7%, over the prior year period primarily due to the COVID-19 recovery discussed above. The gross profit margin on sales to commercial customers decreased to 17.4% from 19.7% in the prior year period, primarily from the benefit of government workforce subsidies including the Payroll Support Program in the CARES Act and other subsidies provided by foreign governments. We recognized a benefit of $2.4 million in cost of sales during the second quarter of fiscal 2022 related to the government subsidies compared to $18.1 million in the prior year quarter.

Gross profit on sales to government and defense customers increased $0.5 million, or 1.7%, over the prior year period. Gross profit margin on sales to government and defense customers increased to 18.1% from 15.0% in the prior year period, primarily driven by cumulative catch-up adjustments on long-term government programs.

Expeditionary Services Segment

Sales in the Expeditionary Services segment decreased $1.3 million, or 7.0%, from the prior year period primarily due to reduced volume for our mobility products. Gross profit in the Expeditionary Services segment increased $1.7 million, or 63.0%, over the prior period primarily due to lower raw material costs. Gross profit margin increased to 25.4% from 14.5% in the prior year period primarily as a result of these lower raw material costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $3.7 million, or 8.5%, over the prior year period primarily due to the reinstatement of full salary and benefits which were temporarily reduced during the prior year quarter as part of our actions to mitigate the financial impact to our business from COVID-19. As a percent of sales, selling, general and administrative expenses remained consistent at 10.8% as the reinstatement of compensation was offset by the favorable impact from our cost reduction actions.

Income Taxes

Our effective income tax rate for continuing operations was 27.5% for the second quarter of fiscal 2022 compared to 26.5% in the prior year period. The increase in the effective tax rate in fiscal 2022 is primarily related to higher non-deductible expenses in fiscal 2022 compared to the prior year.

Discontinued Operations

Loss from discontinued operations was $6.2 million in the prior year period which was attributable to a $6.0 million increase in our reserve to reflect the tentative agreement with the U.S. Department of Justice to settle their investigation of our Contractor-Owned, Contractor-Operated (“COCO”) business under the federal civil False Claims Act.

Six Month Period Ended November 30, 2021

Aviation Services Segment

Sales in the Aviation Services segment increased $106.3 million, or 14.2%, over the prior year period due to a $162.4 million, or 44.9%, increase in sales to commercial customers.  The increase in sales to commercial customers was attributable to increased sales of $53.0 million in our MRO activities as commercial passenger air traffic continues to recover from the impact of COVID-19.  In addition, sales increased $46.3 million in our aftermarket parts trading activities which included whole asset sales of $34.0 million during the six-month period ended November 30, 2021 compared to $14.0 million in the prior year period.

During the six-month period ended November 30, 2021, sales in this segment to government and defense customers decreased $56.1 million, or 14.5%, from the prior year period.  This decrease was primarily attributable to the timing of activities for the C-40 aircraft we are delivering to the Naval Air Systems Command in support of the U.S. Marine Corps.  The prior year period included sales of $39.5 million related to the installation of engines on the aircraft while no engine installation activities occurred in fiscal 2022.

25

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting. During the six-month period ended November 30, 2021, we had net favorable cumulative catch-up adjustments of $4.9 million compared to net favorable cumulative catch-up adjustments of $2.8 million in prior year period. These adjustments primarily relate to our long-term, power-by-the-hour programs where we provide component inventory management and repair services as well as certain long-term government programs.

Cost of sales in Aviation Services increased $82.8 million, or 13.0%, over the prior year period which was in line with the sales increase discussed above.

Gross profit in the Aviation Services segment increased $23.5 million, or 21.1%, over the prior year period. Gross profit on sales to commercial customers increased $20.9 million, or 38.6%, over the prior year period primarily due to the COVID-19 recovery discussed above. In addition, gross profit was unfavorably impacted in the six-month period ended November 30, 2020 due to asset impairment charges of $7.0 million and facility consolidation and repositioning costs of $2.4 million. These items were more than offset by a benefit of $28.2 million in government workforce subsidies from the Payroll Support Program in the CARES Act and other subsidies provided by foreign governments. Gross profit margin on sales to commercial customers decreased to 14.3% from 15.0% in the prior year period primarily due to the impact of the subsidies in the prior year period more than offsetting the volume recovery in fiscal 2022.

Gross profit on sales to government and defense customers increased $2.6 million, or 4.5%, over the prior year primarily driven by cumulative catch-up adjustments on long-term government programs. Gross profit margin on sales to government and defense customers increased to 18.1% from 14.8% in the prior year period primarily as a result of these adjustments.

Expeditionary Services Segment

Sales in the Expeditionary Services segment decreased $19.0 million, or 34.1%, from the prior year period primarily due to reduced volume for our mobility products.  Gross profit in the Expeditionary Services segment increased $1.4 million, or 20.9%, over the prior period primarily due to the divestiture of our composites manufacturing business which was not profitable prior to its divestiture on August 31, 2020.  Gross profit margin increased to 22.0% from 12.0% in the prior year period primarily as a result of the divestiture.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $7.7 million, or 8.7%, over the prior year period primarily due to the reinstatement of full salary and benefits which were temporarily reduced during the prior year period as part of our actions to mitigate the financial impact of COVID-19. As a percent of sales, selling, general and administrative expenses decreased to 10.8% from 11.0% in the prior year period primarily due to the benefit from our actions to reduce both our fixed and variable cost structure in light of the reduced volumes from COVID-19.

Income Taxes

Our effective income tax rate for continuing operations was 26.9% for the six-month period ended November 30, 2021 compared to 73.7% in the prior year period. The prior year period included unfavorable stock compensation items of $0.9 million.

Discontinued Operations

Income from discontinued operations was $0.3 million in the six-month period ended November 30, 2021 compared to a loss of $6.8 million in the prior year period. The loss in the prior year period was attributable to a $6.0 million increase in our legal reserve discussed above.

Liquidity, Capital Resources and Financial Position

Our operating activities are funded and commitments met through the generation of cash from operations. In addition to operations, our current capital resources include an unsecured Revolving Credit Facility and an accounts receivable financing program. Periodically, we may also raise capital through common stock and debt financings in the public or private markets. We continually evaluate various financing arrangements, including the issuance of common stock or debt, which would allow us to improve our liquidity position and finance future growth on commercially reasonable terms. Our continuing ability to borrow from our lenders and issue debt and equity securities to the public and private markets in the future may be negatively affected by a number of factors, including the overall health of the credit markets, general economic conditions, airline industry conditions, geo-political events, and our operating performance. Our ability to generate cash from operations is influenced primarily by our operating performance and changes in working capital.

At November 30, 2021, our liquidity and capital resources included working capital of $626.5 million inclusive of cash of $42.7 million.

We maintain a Revolving Credit Facility with various financial institutions, as lenders, and Bank of America, N.A., as administrative agent for the lenders, which provides the Company an aggregate revolving credit commitment of $600 million and matures September 25, 2024. Under certain circumstances, we have the ability to request, but our lenders are not required to grant, an increase to the revolving credit commitment by an aggregate amount of up to $300 million, not to exceed $900 million in total.

Borrowings under the Revolving Credit Facility bear interest at the offered Eurodollar Rate plus 87.5 to 175 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 0 to 75 basis points based on certain financial measurements if a Base Rate loan.

Borrowings outstanding under the Revolving Credit Facility at November 30, 2021 were $104.5 million and there were approximately $12.1 million of outstanding letters of credit, which reduced the availability of this facility to $483.4 million. There are no other terms or covenants limiting the availability of this facility.

In the first quarter of fiscal 2021, we received $57.2 million from the U.S. Treasury Department through the Payroll Support Program under the CARES Act. This funding included a $48.5 million cash grant, which was to be used exclusively for the continuation of payment of employee wages, salaries and benefits for employees of certain MRO facilities, and a low interest 10-year senior unsecured promissory note of $8.7 million. In fiscal 2021, we recognized the full amount of the grant as contra-expense within Cost of sales and Selling, general and administrative expenses. The Promissory Note was re-paid in full during the fourth quarter of fiscal 2021.

As of November 30, 2021, we also had other financing arrangements that did not limit our availability on the Revolving Credit Facility, including outstanding letters of credit of $11.6 million and foreign lines of credit of $9.7 million.

On October 18, 2017, we entered into a Credit Agreement with the Canadian Imperial Bank of Commerce, as lender (the “Credit Agreement”). The Credit Agreement provided a Canadian $31 million term loan with the proceeds used to fund the acquisition of two MRO facilities in Canada from Premier Aviation. The term loan was paid in full at the expiration of the Credit Agreement on November 1, 2021.

We maintain a Purchase Agreement with Citibank N.A. (“Purchaser”) for the sale, from time to time, of certain accounts receivable due from certain customers (the “Purchase Agreement”). Under the Purchase Agreement, the maximum amount of receivables sold is limited to $150 million and Purchaser may, but is not required to, purchase the eligible receivables we offer to sell. The term of the Purchase Agreement runs through February 22, 2022, however, the Purchase Agreement may also be terminated earlier under certain circumstances. The term of the Purchase Agreement shall be automatically extended for annual terms unless either party provides advance notice that they do not intend to extend the term.

We have no retained interests in the sold receivables, other than limited recourse obligations in certain circumstances, and only perform collection and administrative functions for the Purchaser. We account for these receivable transfers as sales under ASC 860, Transfers and Servicing, and de-recognize the sold receivables from our Condensed Consolidated Balance Sheets.

27

During the six-month periods ended November 30, 2021 and 2020, we sold $158.4 million and $243.1 million, respectively, of receivables under the Purchase Agreement and remitted $176.8 million and $268.5 million, respectively, to the Purchaser on their behalf. As of November 30, 2021 and May 31, 2021, we had collected cash of $3.7 million and $8.4 million, respectively, which was not yet remitted to the Purchaser as of those dates and was classified as Restricted cash on our Condensed Consolidated Balance Sheets.

At November 30, 2021, we were in compliance with all financial and other covenants under our financing arrangements.

On December 16, 2021, our Board of Directors approved a stock repurchase program in which we may repurchase up to $150 million of our common stock with no expiration date. The timing and amount of repurchases are subject to prevailing market conditions and other considerations, including our liquidity and other investment opportunities. We plan to fully utilize the authorization over approximately the next two years.

Cash Flows from Operating Activities

Net cash provided by operating activities–continuing operations was $33.4 million in the six-month period ended November 30, 2021 compared to cash provided of $67.4 million in the prior year period. The decrease from the prior period of $34.0 million was primarily attributable to a higher reduction in inventory levels in the prior year period and the proceeds of a $48.5 million grant from the Payroll Support Program of the CARES Act. These items were partially offset by a $25 million license fee paid to Unison Industries in the prior year period for our expanded and extended exclusive distribution agreement.

Cash Flows from Investing Activities

Net cash used in investing activities was $2.7 million during the six-month period ended November 30, 2021 compared to a cash provided of $5.6 million in the prior year period. The decrease over the prior period was primarily related to proceeds of $10.0 million from the termination of split-dollar life insurance policies in the prior year period.

Cash Flows from Financing Activities

Net cash used in financing activities was $30.1 million during the six-month period ended November 30, 2021 compared to cash used of $382.9 million in the prior year period. The prior year period included the repayment of our additional draw down on our Revolving Credit Facility. These funds were originally drawn in late fiscal 2020 as a precautionary measure in light of the economic and market uncertainty presented by COVID-19.

Critical Accounting Policies and Significant Estimates

We make a number of significant estimates, assumptions and judgments in the preparation of our financial statements. See Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021 for a discussion of our critical accounting policies. There have been no significant changes to the application of our critical accounting policies during fiscal 2022.

Forward-Looking Statements

This report contains certain forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on beliefs of our management, as well as assumptions and estimates based on information available to us as of the dates such assumptions and estimates are made, and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated, depending on a variety of factors, including those factors set forth under Part I, Item 1A in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021. Should one or more of those risks or uncertainties materialize adversely, or should underlying assumptions or estimates prove incorrect, actual results may vary materially from those described. Those events and uncertainties are difficult or impossible to predict accurately and many are beyond our control. We assume no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

28

Item 3 — Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk includes fluctuating interest rates under our credit agreements, changes in foreign exchange rates, and credit losses on accounts receivable. See Note 1 of Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021 for a discussion of accounts receivable exposure.

Foreign Currency Risk. Revenues and expenses of our foreign operations are translated at average exchange rates during the period, and balance sheet accounts are translated at period-end exchange rates. Balance sheet translation adjustments are excluded from the results of operations and are recorded in stockholders’ equity as a component of accumulated other comprehensive loss. A hypothetical 10 percent devaluation of the U.S. dollar against foreign currencies would not have had a material impact on our financial position or continuing operations for the quarter ended November 30, 2021.

Interest Rate Risk. Refer to the section Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021. There were no significant changes during the quarter ended November 30, 2021.

Item 4 — Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of November 30, 2021. This evaluation was carried out under the supervision and with participation of our Chief Executive Officer and our Chief Financial Officer. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Therefore, effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of November 30, 2021, ensuring that information required to be disclosed in the reports that are filed under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported in a timely manner.

There were no changes in our internal control over financial reporting during the quarter ended November 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Note 1 – Basis of Presentation

AAR CORP. and its subsidiaries are referred to herein collectively as “AAR,” “Company,” “we,” “us,” or “our,” unless the context indicates otherwise. The accompanying Condensed Consolidated Financial Statements include the accounts of AAR and its subsidiaries after elimination of intercompany accounts and transactions.

We have prepared these statements without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The Condensed Consolidated Balance Sheet as of May 31, 2021 has been derived from audited financial statements. To prepare the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”), management has made a number of estimates and assumptions relating to the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Certain information and note disclosures, normally included in comprehensive financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to such rules and regulations of the SEC. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2021.

In the opinion of management, the Condensed Consolidated Financial Statements reflect all adjustments (which consist only of normal recurring adjustments) necessary to present fairly the Condensed Consolidated Balance Sheet of AAR CORP. and its subsidiaries as of November 30, 2021, the Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Comprehensive Income (Loss) for the three- and six-month periods ended November 30, 2021 and 2020, the Condensed Consolidated Statements of Cash Flows for the six-month periods ended November 30, 2021 and 2020, and the Condensed Consolidated Statement of Changes in Equity for the three- and six-month periods ended November 30, 2021 and 2020. The results of operations for such interim periods are not necessarily indicative of the results for the full year.

Discontinued Operations

Note 2 – Discontinued Operations

During the third quarter of fiscal 2018, we decided to pursue the sale of our Contractor-Owned, Contractor-Operated (“COCO”) business previously included in our Expeditionary Services segment. Due to this strategic shift, the assets, liabilities, and results of operations of our COCO business have been reported as discontinued operations for all periods presented. Unless otherwise noted, amounts and disclosures throughout these Notes to Condensed Consolidated Financial Statements relate to our continuing operations.

In the fourth quarter of fiscal 2020, we completed the sale of the last operating contract of the COCO business shortly after government approval. Our continuing involvement in the COCO business is limited to the lease of certain aircraft which is an obligation of the acquirer of this contract. The assets and liabilities of our discontinued operations are primarily comprised of right-of-use assets and lease-related liabilities.

In the fourth quarter of fiscal 2021, the post-closing working capital adjustment was finalized resulting in an additional loss of $0.7 million. The sale also included contingent consideration of up to $6.5 million based on the achievement of sales targets over a three-year period subsequent to the sale. Sales forecasts for the Composites business now indicate that it is unlikely that the sales targets will be achieved. We recognized a charge of $1.3 million in the three-month period ended November 30, 2021 to reflect the fair value of the contingent consideration at zero.

Revenue Recognition

Note 4 – Revenue Recognition

Revenue is measured based on the consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer.

Our unit of accounting for revenue recognition is a performance obligation included in our customer contracts. A performance obligation reflects the distinct good or service that we must transfer to a customer. At contract inception, we evaluate if the contract should be accounted for as a single performance obligation or if the contract contains multiple performance obligations. In some cases, our contract with the customer is considered one performance obligation as it includes factors such as the good or service being provided is significantly integrated with other promises in the contract, the service provided significantly modifies or customizes another good or service or the good or service is highly interdependent or interrelated. If the contract has more than one performance obligation, we determine the standalone price of each distinct good or service underlying each performance obligation and allocate the transaction price based on their relative standalone selling prices.

The transaction price of a contract, which can include both fixed and variable amounts, is allocated to each performance obligation identified. Some contracts contain variable consideration, which could include incremental fees or penalty provisions related to performance. Variable consideration that can be reasonably estimated based on current assumptions and historical information is included in the transaction price at the inception of the contract but limited to the amount that is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Variable consideration that cannot be reasonably estimated is recorded when known.

Our performance obligations are satisfied over time as work progresses or at a point in time based on transfer of control of products and services to our customers. The majority of our sales from products are recognized at a point in time upon transfer of control to the customer, which generally occurs upon shipment. In connection with certain sales of products, we also provide logistics services, which include inventory management, replenishment, and other related services. The price of such services is generally included in the price of the products delivered to the customer, and revenues are recognized upon delivery of the product, at which point the customer has obtained control of the product. We do not account for these services separate from the related product sales as the services are inputs required to fulfill part orders received from customers.

For our performance obligations that are satisfied over time, we measure progress in a manner that depicts the performance of transferring control to the customer. As such, we utilize the input method of cost-to-cost to recognize revenue over time as this depicts when control of the promised goods or services is transferred to the customer. Revenue is recognized based on the relationship of actual costs incurred to date to the estimated total cost at completion of the performance obligation. We are required to make certain judgments and estimates, including estimated revenues and costs, as well as inflation and the overall profitability of the arrangement. Key assumptions involved include future labor costs and efficiencies, overhead costs, and ultimate timing of product delivery. Differences may occur between the judgments and estimates made by management and actual program results. For contracts that are deemed to be loss contracts, we establish forward loss reserves for total estimated costs that are in excess of total estimated consideration in the period in which they become known.

When contracts are modified, we consider whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original goods or services provided, are accounted for as if they were part of that existing contract with the effect of the contract modification recognized as an adjustment to revenue on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting. These changes are primarily adjustments to the estimated profitability for our long-term programs where we provide component inventory management and/or repair services.

For the three-month period ended November 30, 2021, we recognized favorable and (unfavorable) cumulative catch-up adjustments of $8.2 million and $(2.3) million, respectively. For the three-month period ended November 30, 2020, we recognized favorable cumulative catch-up adjustments of $2.5 million. When considering these adjustments on a net basis, we recognized net favorable adjustments of $5.9 million and $2.5 million in the three-month periods ended November 30, 2021 and 2020, respectively.

For the six-month period ended November 30, 2021, we recognized favorable and (unfavorable) cumulative catch-up adjustments of $8.2 million and $(3.3) million, respectively. For the six-month period ended November 30, 2020, we recognized favorable cumulative catch-up adjustments of $2.8 million. When considering these adjustments on a net basis, we recognized net favorable adjustments of $4.9 million and $2.8 million in the six-month periods ended November 30, 2021 and 2020, respectively.

Under most of our U.S. government contracts, if the contract is terminated for convenience, we are entitled to payment for items delivered and fair compensation for work performed, the costs of settling and paying other claims, and a reasonable profit on the costs incurred or committed.

We have elected to use certain practical expedients permitted under ASU No. 2014-09, Revenue from Contracts with Customers. Shipping and handling fees and costs incurred associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in Cost of sales on our Condensed Consolidated Statements of Operations, and are not considered a performance obligation to our customers. Our reported sales on our Condensed Consolidated Statements of Operations are net of any sales or related non-income taxes. We also utilize the “as invoiced” practical expedient in certain cases where performance obligations are satisfied over time and the invoiced amount corresponds directly with the value we are providing to the customer.

Contract Assets and Liabilities

The timing of revenue recognition, customer billings, and cash collections results in a contract asset or contract liability at the end of each reporting period. Contract assets consist of costs incurred where revenue recognized over time using the cost-to-cost model exceeds the amounts billed to customers. Contract liabilities include advance payments and billings in excess of revenue recognized. Certain customers make advance payments prior to the satisfaction of our performance obligations on the contract. These amounts are recorded as contract liabilities until such performance obligations are satisfied, either over time as costs are incurred or at a point in time when deliveries are made. Contract assets and contract liabilities are determined on a contract-by-contract basis.

Net contract assets and liabilities are as follows:

	November 30,		May 31,
	2021		2021		Change
Contract assets – current	$	68.5	$	71.9	$	(3.4)
Contract assets – non-current		24.0		21.6		2.4
Contract liabilities:
Deferred revenue – current		(33.6)		(25.9)		(7.7)
Deferred revenue on long-term contracts		(9.1)		(5.4)		(3.7)
Net contract assets	$	49.8	$	62.2	$	(12.4)

Contract assets – non-current is reported within Other non-current assets and Deferred revenue on long-term contracts is reported within Other liabilities on our Condensed Consolidated Balance Sheets. Changes in contract assets and contract liabilities primarily result from the timing difference between our performance of services and payments from customers.

During the three-month period ended August 31, 2020, we terminated a commercial power-by-the-hour (“PBH”) customer contract which resulted in a charge of $2.2 million.

One of our PBH customers notified us in June 2021 that the customer would terminate its contract with us earlier than we originally anticipated. In conjunction with the early termination, we recognized a charge of $5.2 million in the three-month period ended

August 31, 2021, which included a reduction in contract assets and revenue of $1.0 million and the establishment of loss reserves of $4.2 million. As of November 30, 2021, our Condensed Consolidated Balance Sheet included remaining forward loss reserves of $2.2 million classified in Accrued liabilities.

During fiscal 2020, we established forward loss reserves for a certain PBH contract where total estimated costs are in excess of the total estimated consideration over the remainder of the contract. As of November 30, 2021, our Condensed Consolidated Balance Sheet included remaining forward loss reserves of $1.7 million classified in Accrued liabilities.

To support our PBH customer contracts, we previously entered into an agreement with a component repair facility to outsource a portion of the component repair and overhaul services. The agreement included certain minimum repair volume guarantees, which we have not met due to the impact of COVID-19 on commercial passenger aircraft flight hours. During fiscal 2021, we recognized a $4.5 million charge to reflect our estimated obligation over the remainder of the agreement for not achieving the minimum volume guarantees. During the three-month period ended August 31, 2021, we recognized a $1.7 million charge to increase the obligation reflecting the revised estimated shortfall on the minimum volume guarantee. As of November 30, 2021, our Condensed Consolidated Balance Sheet included remaining loss reserves of $4.6 million with $1.5 million classified as current in Accrued liabilities and $3.1 million classified as long-term in Other liabilities.

Changes in our deferred revenue were as follows for the three- and six-month periods ended November 30, 2021 and 2020:

	Three Months Ended				Six Months Ended
	November 30,				November 30,
	2021		2020		2021		2020

Deferred revenue at end of period	$	(42.7)	$	(48.4)	$	(42.7)	$	(48.4)

Remaining Performance Obligations

As of November 30, 2021, we had approximately $780 million of remaining performance obligations, also referred to as firm backlog, which excludes unexercised contract options and potential orders under our indefinite-delivery, indefinite-quantity (IDIQ) contracts. We expect that approximately 50% of this backlog will be recognized as revenue over the next 12 months with approximately 40% of the remainder recognized over the next three years. The amount of remaining performance obligations that are expected to be recognized as revenue beyond 12 months, primarily relates to our long-term programs where we provide component inventory management and/or repair services.

During the six-month period ended November 30, 2020, we incurred severance and furlough-related costs of $8.2 million, which were included as a component of Cost of sales and Selling, general and administrative on our Condensed Consolidated Statements of Operations.

In accordance with ASC 360, Property, Plant and Equipment, we are required to test for impairment of long-lived assets whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable from its undiscounted cash flows. We utilize certain assumptions to estimate future undiscounted cash flows, including demand for our services, future market conditions and trends, business development pipeline of opportunities, current and future lease rates, lease terms, and residual values.

In light of declines in commercial airline volumes and commercial program contract terminations in fiscal 2020 and 2021, we evaluated future cash flows related to certain rotable assets supporting long-term programs and recognized asset impairment charges of $5.8 million in the three-month period ended August 31, 2020.

In conjunction with the early termination notice we received in June 2021 from one of our PBH customers, we evaluated future cash flows related to the rotable assets supporting that fleet type and recognized asset impairment charges of $2.3 million in the three-month period ended August 31, 2021.

Restricted Stock

In the three-month period ended August 31, 2021, as part of our annual long-term stock incentive compensation, we granted 43,010 shares of performance-based restricted stock and 50,845 shares of time-based restricted stock to eligible employees. The grant date fair value per share for these shares was $37.74 (the closing price on the grant date). We also granted 32,307 shares of time-based restricted stock to members of the Board of Directors with a grant date fair value per share of $42.56 (the closing price on the grant date).

Expense charged to operations for restricted stock during each of the three-month periods ended November 30, 2021 and 2020 was $0.8 million and $0.8 million, respectively, and $2.7 million and $2.7 million during the six-month periods ended November 30, 2021 and 2020, respectively.

Stock Options

In July 2021, as part of our annual long-term stock incentive compensation, we granted 143,745 stock options to eligible employees at an exercise price of $37.74 and grant date fair value of $13.36. The fair value of stock options was estimated using the Black-Scholes option pricing model with the following assumptions:

Risk-free interest rate	0.8	%
Expected volatility of common stock	41.6	%
Dividend yield	0.8	%
Expected option term in years	5.3

The total intrinsic value of stock options exercised during the six-month periods ended November 30, 2021 and 2020 was $0.1 million and $0.1 million, respectively. Expense charged to operations for stock options during the three-month periods ended November 30, 2021 and 2020 was $0.9 million and $1.0 million, respectively, and during the six-month periods ended November 30, 2021 and 2020 was $2.1 million and $1.8 million, respectively.

Note 10 – Sale of Receivables

On February 23, 2018, we entered into a Purchase Agreement with Citibank N.A. (“Purchaser”) for the sale, from time to time, of certain accounts receivable due from certain customers (the “Purchase Agreement”). Under the Purchase Agreement, the maximum amount of receivables sold is limited to $150 million and Purchaser may, but is not required to, purchase the eligible receivables we offer to sell. The term of the Purchase Agreement runs through February 22, 2022, however, the Purchase Agreement may also be terminated earlier under certain circumstances. The term of the Purchase Agreement shall be automatically extended for annual terms unless either party provides advance notice that they do not intend to extend the term.

We have no retained interests in the sold receivables, other than limited recourse obligations in certain circumstances, and only perform collection and administrative functions for the Purchaser. We account for these receivable transfers as sales under ASC 860, Transfers and Servicing, and de-recognize the sold receivables from our Condensed Consolidated Balance Sheet.

During the six-month periods ended November 30, 2021 and 2020, we sold $158.4 million and $243.1 million, respectively, of receivables under the Purchase Agreement and remitted $176.8 million and $268.5 million, respectively, to the Purchaser on their behalf. As of November 30, 2021 and May 31, 2021, we had collected cash of $3.7 million and $8.4 million, respectively, which was not yet remitted to the Purchaser as of those dates and was classified as Restricted cash on our Condensed Consolidated Balance Sheets.

We recognize discounts on the sale of our receivables and other fees related to the Purchase Agreement in Other expense, net on our Condensed Consolidated Statements of Operations. We incurred discounts on the sale of our receivables of $0 million and $0.1 million during the three-month periods ended November 30, 2021 and 2020, respectively, and $0.1 million and $0.2 million during the six-month periods ended November 30, 2021 and 2020, respectively.

Note 11 – Government Subsidies

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in the U.S. in response to the COVID-19 pandemic. The CARES Act includes provisions relating to refundable payroll tax credits, deferral of the employer portion of certain payroll taxes, net operating loss carrybacks, and other areas. The payroll tax deferral requires that the deferred payroll taxes be paid over two years, with half of the amount required to be paid by December 31, 2021 and the other half by December 31, 2022. As of November 30, 2021, we have deferred payroll taxes of $12.4 million of which $6.2 million are included in Accrued liabilities and $6.2 million in Other liabilities on our Condensed Consolidated Balance Sheet.

During the three-month period ended August 31, 2020, we received $57.2 million from the U.S. Treasury Department through the Payroll Support Program under the CARES Act. This funding included a $48.5 million cash grant which is to be used exclusively for the continuation of payment of employee wages, salaries and benefits for employees of certain maintenance, repair, and overhaul (“MRO”) facilities. The grant was recognized as contra-expense on our Condensed Consolidated Statement of Operations as the eligible wages, salaries and benefits were incurred. In fiscal 2021, we recognized the full amount of the grant as contra-expense within Cost of sales and Selling, general and administrative expenses of $47.5 million and $1.0 million, respectively.

The remaining funding of $8.7 million was a low interest 10-year senior unsecured promissory note (“Promissory Note”) which included interest at a rate per annum equal to the sum of (i) 1.0% for the first five years, and the applicable secured overnight financing rate plus 2.0% in years six through ten plus (ii) in kind interest of 3.0% for the first five years and increasing by 1.0% each year over the remaining term. The Promissory Note was pre-payable at par at any time and we re-paid the Promissory Note in full during the fourth quarter of fiscal 2021.  Certain corporate restrictions continue to apply to us which include restrictions on employee compensation.  The restrictions previously applicable to us relating to dividends, stock repurchases, and certain workforce actions have lapsed.

Other countries have enacted legislation similar to the CARES Act to provide relief and stimulus measures to assist companies in mitigating the financial impact from COVID-19 and supporting their employees. Our foreign subsidiaries recognized subsidies of $2.5 million and $1.6 million during the three-months ended November 30, 2021 and 2020, respectively, and $2.8 million and $4.9 million during the six-months ended November 30, 2021 and 2020, respectively, from foreign governments which have been deducted from the related expenses on our Condensed Consolidated Statements of Operations.

At November 30, 2021, our debt had a fair value that approximates its carrying value and is classified as Level 2 in the fair value hierarchy.

On October 18, 2017, we entered into a Credit Agreement with the Canadian Imperial Bank of Commerce, as lender (the “Credit Agreement”). The Credit Agreement provided a Canadian $31 million term loan with the proceeds used to fund the acquisition of two MRO facilities in Canada from Premier Aviation. The term loan was paid in full at the expiration of the Credit Agreement on November 1, 2021.

We maintain a Revolving Credit Facility with various financial institutions, as lenders, and Bank of America, N.A., as administrative agent for the lenders, which provides the Company an aggregate revolving credit commitment of $600 million and matures September 25, 2024. Under certain circumstances, we have the ability to request, but our lenders are not required to grant, an increase to the revolving credit commitment by an aggregate amount of up to $300 million, not to exceed $900 million in total. Borrowings under the Revolving Credit Facility bear interest at the offered Eurodollar Rate plus 87.5 to 175 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 0 to 75 basis points based on certain financial measurements if a Base Rate loan.

Borrowings outstanding under the Revolving Credit Facility at November 30, 2021 were $104.5 million and there were approximately $12.1 million of outstanding letters of credit, which reduced the availability of this facility to $483.4 million.

Our financing arrangements also require us to comply with leverage and interest coverage ratios, maintain a minimum net working capital level, and comply with certain affirmative and negative covenants, including those relating to financial reporting and notification, payment of indebtedness, cash dividends, taxes and other obligations, compliance with applicable laws, and limitations on additional liens, indebtedness, acquisitions, investments and disposition of assets. The Revolving Credit Facility also requires our significant domestic subsidiaries, and any subsidiaries that guarantee our other indebtedness, to provide a guarantee of payment under the Revolving Credit Facility. At November 30, 2021, we were in compliance with the financial and other covenants in our financing agreements.

Investments in Joint Ventures

Our investments in joint ventures include $10.7 million for our 40% ownership interest in a joint venture in India to develop and operate an airframe maintenance facility. The facility received certain regulatory approvals and commenced airframe maintenance operations in the second quarter of fiscal 2022.

The investment balance as of November 30, 2021 includes $9.4 million related to the guarantee liability recognized in conjunction with our guarantee of 40% of the Indian joint venture’s debt. The Indian joint venture is accounted for using the equity method. In addition, each of the partners in the Indian joint venture has a loan to the joint venture proportionate to its equity ownership. Our loan to the Indian joint venture under this arrangement was $3.1 million as of November 30, 2021.

License Fees

In June 2011, we entered into a ten-year agreement with Unison Industries (“Unison”) to be the exclusive worldwide aftermarket distributor for Unison’s electrical components, sensors, switches and other systems for aircraft and industrial uses. In June 2020, we entered into an extension and expansion of our agreement with Unison including a new termination date of December 31, 2031, an initial $25.0 million license fee paid in June 2020 to Unison, and annual license fees at a fixed percentage of our net sales of Unison products. The June 2020 payment of $25.0 million was capitalized and is being amortized on a straight-line basis over the term of the new agreement.

Split-Dollar Life Insurance Arrangements

We previously entered into split-dollar life insurance agreements to benefit certain former executives and officers. Under the terms of the arrangements, we made premium payments on the individuals’ behalf, and we retained a collateral interest in the policies generally to the extent of the premiums we previously paid.

During the second quarter of fiscal 2021, certain split-dollar life insurance agreements were terminated and we received $12.0 million for reimbursement of both the life insurance premiums we previously paid and a portion of our prior tax payments made on the individuals’ behalf related to their imputed income on the policies. The reimbursement of the premiums paid of $10.0 million has been classified as cash flow from investing activities with the remainder included in cash flow from operating activities as it represents the reimbursement of a portion of the taxes previously paid and expensed. In the second quarter of fiscal 2021, we recognized a benefit of $1.3 million in Selling, general and administrative expenses on the Condensed Consolidated Statement of Operations for the net recovery of the taxes previously paid on behalf of the individuals.

Earnings per Share

Note 14 – Earnings per Share

The computation of basic earnings per share is based on the weighted average number of common shares outstanding during each period. The computation of diluted earnings per share is based on the weighted average number of common shares outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options and shares issuable upon vesting of restricted stock awards.

In accordance with ASC 260-10-45, Share-Based Payment Arrangements and Participating Securities and the Two-Class Method, our unvested restricted stock awards are deemed participating securities since these shares are entitled to participate in dividends declared on common shares. During periods of net income, the calculation of earnings per share for common stock excludes income attributable to unvested restricted stock awards from the numerator and excludes the dilutive impact of those shares from the denominator. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company.

A reconciliation of the computations of basic and diluted earnings per share information for the three- and six-month periods ended November 30, 2021 and 2020 is as follows:

Business Segment Information

Business Segment Information

Note 16 – Business Segment Information

Consistent with how our chief operating decision making officer (our Chief Executive Officer) evaluates performance and the way we are organized internally, we report our activities in two reportable segments: Aviation Services comprised of supply chain and MRO activities and Expeditionary Services comprised of manufacturing activities.

The Aviation Services segment consists of aftermarket support and services offerings that provide spare parts and maintenance support for aircraft operated by our commercial and government/defense customers. Sales in the Aviation Services segment are derived from the sale and lease of a wide variety of new, overhauled and repaired engine and airframe parts and components to the commercial aviation and government and defense markets. We provide customized inventory supply chain management, performance-based logistics programs, customer fleet management and operations, and aircraft component repair management services. The segment also includes repair, maintenance and overhaul of aircraft, landing gear and components. Cost of sales consists principally of the cost of product, direct labor, and overhead.

The Expeditionary Services segment consists of primarily manufacturing operations with sales derived from the design and manufacture of pallets, shelters, and containers used to support the U.S. military’s requirements for a mobile and agile force, including engineering, design, and system integration services for specialized command and control systems. Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual Report on Form 10-K for the fiscal year ended May 31, 2021.

Our chief operating decision making officer (our Chief Executive Officer) evaluates performance based on our segments and utilizes gross profit as a primary profitability measure. Gross profit is calculated by subtracting cost of sales from sales. The assets and certain expenses related to corporate activities are not allocated to the segments.

Selected financial information for each segment is as follows:

Note 17 – Legal Proceedings

We are not a party to any material pending legal proceeding (including any governmental or environmental proceeding) other than routine litigation incidental to our business, except for the following:

Department of Justice Investigation

As previously reported, the U.S. Department of Justice (“DoJ”), acting through the U.S. Attorney’s Office for the Southern District of Illinois, conducted an investigation of AAR Airlift Group, Inc. (“Airlift”), a wholly-owned subsidiary of AAR CORP., under the federal civil False Claims Act (“FCA”). The investigation related to Airlift’s performance of several contracts awarded by the U.S. Transportation Command (“TRANSCOM”) concerning the operations and maintenance of rotary-wing and fixed-wing aircraft in Afghanistan and Africa, as well as several U.S. Navy contracts. In June 2018, the DoJ informed Airlift that part of the investigation was precipitated by a lawsuit filed under the qui tam provisions of the FCA by a former employee of Airlift.

In June 2021, Airlift and the DoJ reached an agreement to settle the FCA investigation and related matters for approximately $11.5 million which concluded the DoJ investigation into Airlift’s contracts with TRANSCOM and the U.S. Navy. As part of the settlement, Airlift and AAR did not admit any wrongdoing.

We recognized charges of $11.0 million in discontinued operations in fiscal 2021 related to this agreement and related matters. As of May 31, 2021, our reserve was $12.7 million and payment for the entire matter was made in the first quarter of fiscal 2022.

Self-Reporting of Potential Foreign Corrupt Practices Act Violations

The Company retained outside counsel to investigate possible violations of the Company’s Code of Conduct, the U.S. Foreign Corrupt Practices Act, and other applicable laws, relating to the Company’s activities in Nepal and South Africa. Based on these investigations, in fiscal 2019, we self-reported these matters to the DoJ, the U.S. Securities and Exchange Commission and the UK Serious Fraud Office. The Company is fully cooperating with the reviews by these agencies, although we are unable at this time to predict what action, if any, they may take.
