NOTE A—SUMMARY OF FINANCIAL STATEMENT PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Air Transport Services Group, Inc. ("ATSG" and, together with its subsidiaries, the "Company," "we," "us," and "our") is a holding company whose subsidiaries lease aircraft and provide contracted airline operations as well as other support services mainly to the air transportation, e-commerce and package delivery industries.

ATSG's leasing subsidiary, Cargo Aircraft Management, Inc. (“CAM”), leases aircraft to each of ATSG's airline subsidiaries as well as to non-affiliated airlines and other lessees. ATSG's airline subsidiaries, ABX Air, Inc. (“ABX”), Air Transport International, Inc. (“ATI”) and Omni Air International, LLC ("OAI") each have the authority, through their separate U.S. Department of Transportation ("DOT") and Federal Aviation Administration ("FAA") certificates, to transport cargo worldwide. The Company provides a combination of aircraft, crews, maintenance and insurance services for its customers' transportation networks through crew, maintenance and insurance ("CMI") agreements and aircraft, crew, maintenance and insurance ("ACMI") agreements and through charter contracts in which aircraft fuel is also included.

In addition to its aircraft leasing and airline services, the Company offers a range of complementary services to delivery companies, freight forwarders, airlines and government customers. These include aircraft maintenance and modification services, aircraft parts supply, equipment maintenance services and load transfer and package sorting services.

Basis of Presentation

The financial statements of the Company are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The accompanying unaudited condensed interim consolidated financial statements are prepared in conformity with GAAP and such principles are applied on a basis consistent with the financial statements reflected in our 2021 Form 10-K. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations promulgated by the SEC related to interim financial statements. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring adjustments, necessary for the fair presentation of the Company's results of operations and financial position for the periods presented. Due to seasonal fluctuations, among other factors common to the air cargo industry, the results of operations for the periods presented are not necessarily indicative of the results of operations to be expected for the entire year or any interim period. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. The accounting estimates reflect the best judgment of management, but actual results could differ materially from those estimates.

The accompanying unaudited condensed consolidated financial statements include the accounts of ATSG and its wholly-owned subsidiaries. Inter-company balances and transactions are eliminated. Investments in affiliates in which the Company has significant influence but does not exercise control are accounted for using the equity method of accounting. Under the equity method, the Company's share of the nonconsolidated affiliate's income or loss is recognized in the consolidated statement of earnings and cumulative post-acquisition changes in the investment are adjusted against the carrying amount of the investment.

Uncertainties

The Company has experienced disruptions to its operations, such as shortages of personnel, parts shortages, maintenance delays, shortages of transportation and hotel accommodations for flight crews, facility closures and other supply chain related issues as a result of the COVID-19 pandemic. The emergence of COVID-19 variants could result in reduced revenues, additional costs and supply chain delays for the Company. The extent of the impact that the coronavirus pandemic will have on our future operations and financial results will depend on future developments, including: the duration, spread, severity and recurrence of the COVID-19 variants; vaccination rates, the effectiveness of vaccines, the duration and scope of government orders and local restrictions as well as the extent of the impact of the pandemic on overall economic conditions.

In February 2022, war started in Ukraine, intensifying geopolitical pressures worldwide. While the Company's operations have not been detrimentally impacted directly, additional supply chain disruptions and inflationary pressures could have an impact on overall economic conditions, as well as the Company's operations and financial results.

Accounting Standards Updates

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-06, "Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"). This new standard removes the separation models for convertible debt with cash conversion or beneficial conversion features. It eliminates the "treasury stock" method for convertible instruments and requires application of the “if-converted” method for certain agreements. The Company adopted ASU 2020-06 on January 1, 2022 using the modified retrospective approach which resulted in the following adjustments:

(in thousands)	December 31, 2021		Adoption of ASU 2020-06		January 1, 2022
Balance Sheet line item:
Principal value	$	(258,750)	$	—	$	(258,750)
Unamortized issuance cost	$	2,889	$	—	$	2,889
Unamortized discount	$	24,215	$	(24,215)	$	—
Convertible Debt	$	(231,646)	$	(24,215)	$	(255,861)
Net deferred tax liability	$	(217,291)	$	5,527	$	(211,764)
Additional paid-in capital	$	(1,074,286)	$	39,559	$	(1,034,727)
Retained earnings	$	(309,430)	$	(20,871)	$	(330,301)

After adopting ASU 2020-06, the Company's Convertible Notes due 2024 (as defined and discussed in Note F) are reflected entirely as a liability as the embedded conversion feature is no longer separately presented within stockholders' equity, which also eliminated the non-cash discount. Accordingly, earnings no longer reflect the discount amortization expense which was $6.4 million of interest expense, net of income taxes during 2021. After giving effect for the adoption, the effective interest rate on the Convertible Notes is 1.5%.

ASU 2020-06 requires the application of the more dilutive if-converted method when calculating the impact of the Convertible Notes on earnings per diluted share. The adoption of ASU 2020-06 does not change the accounting treatment of shares to be delivered by the convertible note hedges (see Note F) purchased by the Company that are designed to offset the shares issued to settle its Convertible Notes, which are anti-dilutive and not reflected in earnings per diluted share.

The airline certificates have an indefinite life and therefore are not amortized. The Company amortizes finite-lived intangibles assets, including customer relationship and Supplemental Type Certificates ("STC") intangibles, over 4 to 17 remaining years.

Stock warrants issued to Amazon (see Note C) as an incentive for Amazon subsidiary ASI to lease aircraft from the Company are recorded as a lease incentive asset using their fair value at the time that the lessee has met its performance obligations and if probable of vesting at the time of issuance, and amortized against revenues over the duration of related aircraft leases. The Company's lease incentive granted to the lessee was as follows (in thousands):

Carrying value as of December 31, 2021	$	102,913
Amortization	(11,620)
Carrying value as of June 30, 2022	$	91,293

The Company has a 49% ownership in a joint-venture agreement with Precision Aircraft Solutions, LLC, to develop a passenger-to-freighter conversion program for Airbus A321-200 aircraft. In April of 2022, the Company acquired a 40% ownership interest in the joint-venture company GA Telesis Engine Services, LLC to provide engine tear-down services to harvest and sell engine parts. The Company accounts for its investment in these joint ventures under the equity method of accounting, in which the carrying value of each investment is reduced for the Company's share of the non-consolidated affiliates' operating results.

The carrying value of the joint ventures totaled $21.6 million and $10.3 million at June 30, 2022 and December 31, 2021, respectively, and are reflected in “Other Assets” in the Company’s consolidated balance sheets. The Company monitors its investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis in accordance with GAAP. If the Company determines that an other-than-temporary decline in value has occurred, it recognizes an impairment loss, which is measured as the difference between the recorded carrying value and the fair value of the investment. The fair value is generally determined using an income approach based on discounted cash flows or using negotiated transaction values.

DoD

The Company is a provider of cargo and passenger airlift services to the U.S. Department of Defense ("DoD"). The DoD awards flights to U.S. certificated airlines through annual contracts and through temporary "expansion" routes.

DHL

The Company has had long-term contracts with DHL Network Operations (USA), Inc. and its affiliates ("DHL") since August 2003. The Company leases Boeing 767 aircraft to DHL under both long-term and short-term lease agreements. Under a separate CMI agreement, the Company operates Boeing 767 aircraft that DHL leases from the Company. Pricing for services provided through the CMI agreement is based on pre-defined fees, scaled for the number of aircraft operated and the number of flight crews provided to DHL for its U.S. network. The Company provides DHL with scheduled maintenance services for aircraft that DHL leases. The Company also provides additional air cargo transportation services for DHL through ACMI agreements in which the Company provides the aircraft, crews, maintenance and insurance under a single contract. As of June 30, 2022, the Company leased 15 Boeing 767 freighter aircraft to DHL comprised of four Boeing 767-200 aircraft and eleven Boeing 767-300 aircraft, with expirations between 2023 and 2029. In February 2022, the Company and DHL agreed to a six-year extension of its dry leases for five Boeing 767 freighters as well as an extension of the CMI agreements to operate aircraft through April 2028.

Amazon

The Company has been providing freighter aircraft, airline operations and services for cargo handling and logistical support for Amazon.com Services, LLC ("ASI"), successor to Amazon.com Services, Inc., a subsidiary of Amazon.com, Inc. ("Amazon") since September 2015. On March 8, 2016, the Company entered into an Air Transportation Services Agreement (the “ATSA”) with ASI, pursuant to which CAM leases Boeing 767 freighter aircraft to ASI. The ATSA also provides for the operation of aircraft by the Company’s airline subsidiaries, and the management of ground services by the Company's subsidiary LGSTX Services, Inc. ("LGSTX"). As of June 30,

12

2022, the Company leased 30 Boeing 767-300 and 12 Boeing 767-200 freighter aircraft to ASI with lease expirations between 2023 and 2031.

Amazon Investment Agreement

In conjunction with the execution of the ATSA, the Company and Amazon entered into an Investment Agreement on March 8, 2016 (the "2016 Investment Agreement") and a Stockholders Agreement on March 8, 2016. The 2016 Investment Agreement called for the Company to issue warrants in three tranches granting Amazon the right to acquire up to 19.9% of the Company’s outstanding common shares as described below. The first tranche of warrants, issued upon the execution of the 2016 Investment Agreement and all of which are now fully vested, granted Amazon the right to purchase approximately 12.81 million ATSG common shares, with the first 7.69 million common shares vesting upon issuance on March 8, 2016, and the remaining 5.12 million common shares vesting as the Company delivered additional aircraft leased under the ATSA. The second tranche of warrants, which were issued and vested on March 8, 2018, granted Amazon the right to purchase approximately 1.59 million ATSG common shares. The third tranche of warrants vested on September 8, 2020, and granted Amazon the right to purchase an additional 0.5 million ATSG common shares to bring Amazon’s ownership, after the exercise in full of the three tranches of warrants, to 19.9% of the Company’s pre-transaction outstanding common shares measured on a GAAP-diluted basis, adjusted for share issuances and repurchases by the Company following the date of the 2016 Investment Agreement and after giving effect to the warrants granted. The exercise price of the 14.9 million warrants issued under the 2016 Investment Agreement was $9.73 per share, which represents the closing price of ATSG’s common shares on February 9, 2016. Each of the three tranches of warrants were exercisable in accordance with their terms through March 8, 2021 (subject to extension if regulatory approvals, exemptions, authorizations, consents or clearances have not been obtained by such date).

On March 5, 2021, Amazon exercised warrants from the 2016 Investment Agreement for 865,548 shares of the Company's common stock through a cashless exercise by forfeiting 480,047 warrants from the 2016 Investment Agreement as payment. For the cashless exchange, ATSG shares were valued at $27.27 per share, its volume-weighted average price for the previous 30 trading days immediately preceding March 5, 2021. Also on March 5, 2021, Amazon notified the Company of its intent to exercise warrants from the 2016 Investment agreement for 13,562,897 shares of the Company's common stock by paying $132.0 million of cash to the Company. This exercise was contingent upon the approval of the DOT, and the expiration or termination of any applicable waiting period pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976. After receiving all required regulatory approvals and clearances, Amazon remitted the funds to the Company on May 7, 2021, and the Company issued the corresponding shares of common stock, completing the warrant exercise.

On December 22, 2018, the Company announced agreements with ASI to 1) lease and operate ten additional Boeing 767-300 aircraft, 2) extend the term of the 12 Boeing 767-200 aircraft currently leased to ASI by two years to 2023 with an option for three more years, 3) extend the term of the eight Boeing 767-300 aircraft currently leased to ASI by three years to 2026 and 2027 with an option for three more years, and 4) extend the ATSA by five years through March 2026, with an option to extend for an additional three years. The Company leased all ten of the 767-300 aircraft in 2020. In conjunction with the commitment for ten additional 767 aircraft leases, extensions of twenty existing Boeing 767 aircraft leases and the ATSA described above, Amazon and the Company entered into another Investment Agreement on December 20, 2018 (the "2018 Investment Agreement"). Pursuant to the 2018 Investment Agreement, the Company issued Amazon warrants for 14.8 million ATSG common shares. This group of warrants will expire if not exercised within seven years from their issuance date, in December of 2025 (subject to extension if regulatory approvals, exemptions, authorizations, consents or clearances have not been obtained by such date). The warrants have an exercise price of $21.53 per share.

On May 29, 2020, ASI agreed to lease 12 more Boeing 767-300 aircraft from the Company. The first of these leases began in the second quarter of 2020 with the remaining 11 leases commencing in 2021. All 12 of these aircraft leases were for 10-year terms. Pursuant to the 2018 Investment Agreement, as a result of leasing these 12 aircraft, Amazon was issued warrants for 7.0 million common shares, all of which have vested. These warrants will expire if not exercised by December 20, 2025 (subject to extension if regulatory approvals, exemptions, authorizations, consents or clearances have not been obtained by such date). The exercise price of these warrants is $20.40 per share.

13

Issued and outstanding warrants are summarized below as of June 30, 2022:

		Common Shares in millions
	Exercise price	Vested	Non-Vested	Expiration
2018 Investment Agreement	$21.53	14.8	0.0	December 20, 2025
2018 Investment Agreement	$20.40	7.0	0.0	December 20, 2025

Additionally, Amazon can earn incremental warrants rights of up to 2.9 million common shares under the 2018 Investment Agreement by leasing up to five more cargo aircraft from the Company before January 2026. Incremental warrants granted to Amazon for ASI’s commitment to any such future aircraft leases will have an exercise price based on the volume-weighted average price of the Company's shares during the 30 trading days immediately preceding the contractual commitment for each lease.

For all outstanding warrants vested, Amazon may select a cashless conversion option. Assuming ATSG's stock price at the time of conversion is above the warrant exercise price, Amazon would receive fewer shares in exchange for any warrants exercised under the cashless option by surrendering the number of shares with a market value equal to the exercise price.

The Company’s accounting for the warrants has been determined in accordance with the financial reporting guidance for financial instruments. Warrants classified as liabilities are marked to fair value at the end of each reporting period. The value of warrants is recorded as a customer incentive asset if it is probable of vesting at the time of grant and further changes in the fair value of warrant obligations are recorded to earnings. Upon a warrant vesting event, the customer incentive asset is amortized as a reduction of revenue over the duration of the related revenue contract.

In accordance with the 2016 Investment Agreement, on September 8, 2020, the final number of shares issuable under the third tranche of warrants was determined to be 0.5 million common shares. As a result, under GAAP, the value of the entire warrant grant under the 2016 Investment Agreement was remeasured on September 8, 2020, and its fair value of $221 million was reclassified from balance sheet liabilities to paid-in-capital. In October 2020, upon the execution of the 10th and final aircraft lease of the December 2018 commitment, warrants for 14.8 million shares were remeasured on October 1, 2020, and their fair value of $154 million was reclassified from balance sheet liabilities to paid-in-capital. In December 2021, upon execution of the 12th and final aircraft lease of the May 2020 commitment, warrants for 7.0 million shares were remeasured on December 7, 2021, and their fair value of $82.4 million was reclassified from balance sheet liabilities to paid-in-capital.

As of June 30, 2022 and December 31, 2021, the Company's liabilities reflected warrants from the 2018 Amazon agreements having a fair value of $0.9 million and $0.9 million, respectively. During the three and six months ended June 30 , 2022 the re-measurements of warrants to fair value resulted in a gain of $0.1 million and $0.1 million before the effect of income taxes, respectively, compared to gains of $33.5 million and $40.4 million before the effect of income taxes, respectively, for the corresponding periods of 2021.

The Company's earnings in future periods will be impacted by the re-measurements of warrant fair value, amortizations of the lease incentive asset and the related income tax effects. For income tax calculations, the value and timing of related tax deductions will differ from the guidance described above for financial reporting.

NOTE D—FAIR VALUE MEASUREMENTS

The Company’s money market funds and interest rate swaps are reported on the Company’s consolidated balance sheets at fair values based on market values from comparable transactions. The fair value of the Company’s money market funds, Convertible Notes (as defined in Note F), convertible note hedges and interest rate swaps are based on observable inputs (Level 2) from comparable market transactions.

The fair value of the stock warrant obligations to Amazon resulting from aircraft leased to ASI were determined using a Black-Scholes pricing model which considers various assumptions, including the Company’s common stock price, the volatility of the Company’s common stock, the expected dividend yield, exercise price and the risk-free interest rate (Level 2 inputs). The fair value of the stock warrant obligations for unvested stock warrants, conditionally promised to Amazon for the execution of incremental, future aircraft leases, include additional

14

assumptions including the expected exercise prices and the probabilities that future leases will occur (Level 3 inputs).

The following table reflects assets and liabilities that are measured at fair value on a recurring basis (in thousands):

As a result of lower market interest rates compared to the stated interest rates of the Company’s fixed rate debt obligations, the fair value of the Company’s debt obligations, based on Level 2 observable inputs, was approximately $25.6 million less than the carrying value, which was $1,359.5 million at June 30, 2022. As of December 31, 2021, the fair value of the Company’s debt obligations was approximately $37.1 million less than the carrying value, which was $1,299.4 million. The non-financial assets, including goodwill, intangible assets and property and equipment are measured at fair value on a non-recurring basis.

The Company is party to a syndicated credit agreement (as amended, the "Senior Credit Agreement") which includes the ability to execute term loans and a revolving credit facility. Prior to its amendment on April 6, 2021, the Senior Credit Agreement had a maturity date of November 2024 provided certain liquidity measures are maintained during 2024, an incremental accordion capacity based on debt ratios and a maximum revolver capacity of $600.0 million. The interest rate is a pricing premium added to LIBOR based upon the ratio of the Company's debt to its earnings before interest, taxes, depreciation and amortization expenses ("EBITDA") as defined under the Senior Credit Agreement.

On April 6, 2021, the Company amended the Senior Credit Agreement ("Amended Credit Agreement"). The Amended Credit Agreement: (i) temporarily increased the aggregate amount of the revolving credit facility from $600.0 million to $1 billion, and subsequently decreased the aggregate amount to $800.0 million on April 13, 2021, (ii) permitted increases of the revolving credit facility commitments and/or new tranches of term loans in an aggregate principal amount equal to the sum of $400 million plus the principal amount of indebtedness that could be incurred at the time of the increase that would not cause the Secured Leverage Ratio (as defined in the Amended Credit Agreement) to exceed 3.25 to 1.00 on a pro forma basis, (iii) modified the maturity date of the agreement from November 30, 2024, to April 6, 2026, with such extension of the maturity date being subject to (1) at the election of the lenders, five one-year extensions and (2) an earlier springing maturity date of July 12, 2024, if, on such date, (a) more than $75.0 million in aggregate principal amount of the Convertible Notes (as defined below) remain outstanding and (b) the Company has less than $375.0 million of liquidity at such time, (iv) removed the Collateral to Total Exposure Ratio (as defined in the Senior Credit Agreement) as a financial covenant, and (v) required the Company to repay the balance of all term loans outstanding at the time of the amendment.

On January 28, 2020, CAM completed a debt offering of $500.0 million in senior unsecured notes (together with the "Additional Notes" referred to below, the “Senior Notes”) that were guaranteed by ATSG and certain of its other subsidiaries. The Senior Notes were sold only to qualified institutional buyers in the United States pursuant to Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”), and certain investors pursuant to Regulation S under the Securities Act. The Senior Notes are senior unsecured obligations that bear interest at a fixed rate of 4.75% per year, payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2020. The Senior Notes mature on February 1, 2028. The Senior Notes contain customary events of default and certain covenants which are generally no more restrictive than those set forth in the Senior Credit Agreement. The net proceeds of $495.0 million from the Senior Notes were used to pay down the revolving credit facility. The Senior Notes do not require principal payments until maturity but prepayments are allowed without penalty beginning February 1, 2025.

As of June 30, 2022, the unused revolving credit facility available to the Company at the trailing twelve-month EBITDA level was $269.7 million with additional permitted indebtedness under the Senior Credit Agreement subject to compliance with other covenants.

On April 13, 2021, CAM completed its offering of $200.0 million of additional Senior Notes that were guaranteed by ATSG and certain of its subsidiaries. The additional Senior Notes are fully fungible with the original Senior Notes, treated as a single class for all purposes under the indenture governing all the Senior Notes with the same terms (other than issue date and issue price). The proceeds of $205.5 million, net of scheduled interest

16

payable, were used, in conjunction with draws from the revolving credit facility to repay the unsubordinated term loans. Upon retirement of the unsubordinated term loans, the Company expensed debt issuance costs of $6.5 million related to the unsubordinated term loans.

During the three month period ended June 30, 2022, the Company repurchased Senior Notes having a principal value of $120.0 million in the open market at a 5.5% reducing the Senior Notes carrying value to $577.9 million. The Company recognized a net pre-tax gain of $4.5 million, net of fees which was recorded under net gain of financial instruments on the income statement during the corresponding period.

The balance of the Senior Notes is net of debt issuance costs of $5.9 million and $7.8 million as of June 30, 2022 and December 31, 2021, respectively. Under the terms of the Senior Credit Agreement, interest rates are adjusted at least quarterly based on the Company's EBITDA, its outstanding debt level and prevailing LIBOR or prime rates. At the Company's debt-to-EBITDA ratio as of June 30, 2022, the LIBOR based financing for the revolving credit facility bear variable interest rates of 2.62%.

The Senior Credit Agreement is collateralized by certain of the Company's Boeing 777, 767 and 757 aircraft. Under the terms of the Senior Credit Agreement, the Company is required to maintain certain collateral coverage ratios set forth in the Senior Credit Agreement. The Senior Credit Agreement limits the amount of dividends the Company can pay and the amount of common stock it can repurchase to $100.0 million during any calendar year, provided the Company's total debt to EBITDA ratio is under 3.50 to 1.0 and the secured debt to EBITDA ratio is under 3.0 to 1.0, after giving effect to the dividend or repurchase. The Senior Credit Agreement contains covenants, including a maximum permitted total EBITDA to debt ratio, a fixed charge covenant ratio requirement, and limitations on certain additional indebtedness and guarantees of indebtedness. The Senior Credit Agreement stipulates events of default, including unspecified events that may have material adverse effects on the Company. If an event of default occurs, the Company may be forced to repay, renegotiate or replace the Senior Credit Agreement.

In September 2017, ATSG issued $258.8 million aggregate principal amount of 1.125% convertible senior notes due 2024 ("Convertible Notes") in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Convertible Notes bear interest at a rate of 1.125% per year payable semi-annually in arrears on April 15 and October 15 each year, beginning April 15, 2018. The Convertible Notes mature on October 15, 2024, unless repurchased or converted in accordance with their terms prior to such date. The Convertible Notes are unsecured indebtedness, subordinated to the Company's existing and future secured indebtedness and other liabilities, including trade payables.

Conversion of the Convertible Notes can only occur upon satisfaction of certain conditions and during certain periods, beginning any calendar quarter commencing after December 31, 2017, until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon the occurrence of certain fundamental changes, holders of the Convertible Notes can require the Company to repurchase their notes at the cash repurchase price equal to the principal amount of the notes, plus any accrued and unpaid interest. The Company has the right to settle the Convertible Notes in cash, the Company’s common shares or a combination of cash and the Company’s common shares, at the Company’s election. The initial conversion rate is 31.35 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $31.90 per common share). If a “make-whole fundamental change” (as defined in the offering circular with the Convertible Notes) occurs, the Company will, in certain circumstances, increase the conversion rate for a specified period of time.

17

The conversion feature of the Convertible Notes required bifurcation from the principal amount under the applicable accounting guidance. On January 1, 2022 the Company adopted ASU 2020-06 using the modified retrospective approach as discussed in Note A which recombined the value of the previously bifurcated embedded feature with the convertible note and eliminated the discount. The carrying value of the Company's convertible debt is shown below (in thousands):

	June 30,		December 31,
	2022		2021
Principal value, Convertible Notes, due 2024	$	258,750	$	258,750
Unamortized issuance costs	(2,373)		(2,889)
Unamortized discount	—		(24,215)
Convertible debt	$	256,377	$	231,646

In conjunction with the Convertible Notes, the Company purchased convertible note hedges under privately negotiated transactions for $56.1 million, having the same number of the Company's shares of common stock (8.1 million shares) and the same strike price ($31.90) that underlie the Convertible Notes. The convertible note hedges are expected to reduce the potential equity dilution with respect to the Company's common stock and/or offset any cash payments in excess of the principal amount due, as the case may be, upon conversion of the Convertible Notes. The Company's current intent and policy is to settle all Note conversions through a combination settlement which satisfies the principal amount of the Convertible Notes outstanding with cash.

NOTE G—DERIVATIVE INSTRUMENTS

The Company maintains derivative instruments for protection from fluctuating interest rates. The table below provides information about the Company’s interest rate swaps (dollars in thousands):

			June 30, 2022				December 31, 2021
Expiration Date	Stated Interest Rate		Notional Amount		Market Value (Liability)		Notional Amount		Market Value (Liability)
March 31, 2022	1.900	%	$	—	$	—	$	50,000	$	(221)
March 31, 2022	1.950	%	—		—		75,000		(341)
March 31, 2023	2.425	%	129,375		518		133,125		(3,041)

The outstanding interest rate swaps are not designated as hedges for accounting purposes. The effects of future fluctuations in LIBOR interest rates on derivatives held by the Company will result in the recording of unrealized gains and losses into the statement of operations. The Company recorded net gains on derivatives of $1.4 million and $4.1 million for the three and six month periods ending June 30, 2022, respectively, compared to net gains of $2.3 million and $4.8 million for the corresponding periods of 2021. The liability for outstanding derivatives is recorded in other liabilities and in accrued expenses.

NOTE H—COMMITMENTS AND CONTINGENCIES

Payroll Support Programs

During 2020, two of the Company's airline subsidiaries, OAI and ATI, received government funds totaling $75.8 million pursuant to payroll support program agreements under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). In February 2021, OAI was approved for $37.4 million of additional non-repayable government funds pursuant to a payroll support program agreement under the Consolidated Appropriations Act, 2021 (the “PSP Extension Law”). This grant was subsequently increased by $5.6 million. Further, in April 2021, OAI was approved for $40.0 million of additional non-repayable government funds pursuant to a payroll support program agreement under the American Rescue Plan Act of 2021 (the "American Rescue Plan").

18

The three programs are structured in a substantially similar manner. These grants are not required to be repaid if the Company complies with the provisions of the payroll support program agreements under the CARES Act, the PSP Extension Law and the American Rescue Plan. The grants are recognized over the periods in which the Company recognizes the related expenses for which the grants are intended to compensate. The Company recognized the grants as contra-expense during the periods in which passenger flight operations and combi flight operations levels were expected to be negatively impacted by the pandemic. During the three month and six month periods ended June 30 2021, the Company recognized $38.3 million and $66.3 million of the grants, respectively. The Company recognized all of the CARES Act funds by the end of 2021.

In conjunction with the payroll support program agreements under the CARES Act, OAI and ATI agreed on behalf of themselves and ABX to refrain from conducting involuntary furloughs or reducing employee rates of pay or benefits through September 30, 2020. Thereafter, OAI agreed as a condition of receiving grants under the PSP Extension Law and the American Rescue Plan to refrain from conducting involuntary furloughs or reducing employee rates of pay or benefits through March 31, 2021, and September 30, 2021, respectively. Under the CARES Act, OAI and ATI agreed to limit, on behalf of themselves and certain affiliates, executive compensation through March 24, 2022; maintain certain air transportation service through March 1, 2022 as may be required by the DOT pursuant to its authority under the CARES Act; and maintain certain internal controls and records relating to the funds and comply with certain reporting requirements. OAI further agreed as a condition of receiving grants under the PSP Extension Law and thereafter the American Rescue Plan, to limit executive compensation through October 1, 2022 and April 1, 2023, respectively. In addition, the Company may not pay dividends or repurchase its shares through September 30, 2022.

Lease Commitments

The Company leases property, aircraft, aircraft engines and other types of equipment under operating leases. The Company's airlines operate seven freighter aircraft provided by customers and four passenger aircraft leased from external companies. Property leases include hangars, warehouses, offices and other space at certain airports with fixed rent payments and lease terms ranging from one month to six years. The Company is obligated to pay the lessor for maintenance, real estate taxes, insurance and other operating expenses on certain property leases. These expenses are variable and are not included in the measurement of the lease asset or lease liability. These expenses are recognized as variable lease expense when incurred and are not material. Equipment leases include ground support and industrial equipment as well as computer hardware with fixed rent payments and terms of one month to five years.

The Company records the initial right-to-use asset and lease liability at the present value of lease payments scheduled during the lease term. For the six month period ending June 30, 2022 and 2021, non-cash transactions to recognize right-to-use assets and corresponding liabilities for new leases were $12.7 million and $5.9 million, respectively. Unless the rate implicit in the lease is readily determinable, the Company discounts the lease payments using an estimated incremental borrowing rate at the time of lease commencement. The Company estimates the incremental borrowing rate based on the information available at the lease commencement date, including the rate the Company could borrow for a similar amount, over a similar lease term with similar collateral. The Company's weighted-average discount rate for operating leases at June 30, 2022 was 2.3% compared to 2.4% at December 31, 2021. Leases often include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. Although not material, the amount of such options is reflected below in the maturity of operating lease liabilities table. Lease expense is recognized on a straight-line basis over the lease term. The weighted-average remaining lease term is 3.5 years and 3.8 years as of June 30, 2022 and December 31, 2021, respectively.

19

For the six month periods ending June 30, 2022 and 2021, cash payments against operating lease liabilities were $11.0 million and $10.7 million, respectively. As of June 30, 2022, the maturities of operating lease liabilities are as follows (in thousands):

	Operating Leases
Remaining 2022	$	11,280
2023	20,381
2024	16,239
2025	12,233
2026	6,698
2027 and beyond	514
Total undiscounted cash payments	67,345
Less: amount representing interest	(2,543)
Present value of future minimum lease payments	64,802
Less: current obligations under leases	20,497
Long-term lease obligation	$	44,305

Purchase Commitments

The Company has agreements with vendors for the conversion of Boeing 767-300, Airbus A321 and Airbus A330 passenger aircraft into a standard configured freighter aircraft. The conversions primarily consist of the installation of a standard cargo door and loading system. As of June 30, 2022, the Company owned fourteen Boeing 767-300 aircraft and five Airbus A321-200 aircraft that were in or awaiting the modification process. As of June 30, 2022, the Company has agreements to purchase eleven more Boeing 767-300 passenger aircraft, four more Airbus A321 passenger aircraft and six Airbus A330 passenger aircraft through 2024. As of June 30, 2022, the Company's commitments to acquire and complete the conversion of these aircraft totaled $707.0 million, including estimated payments of $415.4 million through 2023 and the remaining payments through 2026. Actual conversion payments will be based on the achievement of process milestones.

Guarantees and Indemnifications

Certain leases and agreements of the Company contain guarantees and indemnification obligations to the lessor, or one or more other parties, that are considered reasonable and customary (e.g. use, tax and environmental indemnifications), the terms of which range in duration and are often limited. Such indemnification obligations may continue after expiration of the respective lease or agreement.

Other

In addition to the foregoing matters, the Company is also a party to legal proceedings in various federal and state jurisdictions from time to time arising out of the operation of the Company's business. The amount of alleged liability, if any, from these proceedings cannot be determined with certainty; however, the Company believes that its ultimate liability, if any, arising from pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are probable of assertion, taking into account established accruals for estimated liabilities, should not be material to our financial condition or results of operations.

20

Employees Under Collective Bargaining Agreements

As of June 30, 2022, the flight crewmember employees of ABX, ATI and OAI and flight attendant employees of ATI and OAI were represented by the labor unions listed below:

Airline	Labor Agreement Unit	Percentage of the Company’s Employees
ABX	International Brotherhood of Teamsters	5.8%
ATI	Air Line Pilots Association	9.7%
OAI	International Brotherhood of Teamsters	6.1%
ATI	Association of Flight Attendants	0.6%
OAI	Association of Flight Attendants	5.8%

The labor agreements with ATI 's flight crew members and Omni's flight crew members are amendable at this time. Under the Railway Labor Act, as amended, airline labor agreements do not expire, so the existing contract remains in effect throughout the negotiation process.

Subsequent Event

On August 7, 2022 the fire suppression system discharged at one of the Company's aircraft maintenance hangars in Wilmington, Ohio. The event impacted employees, three aircraft and equipment in and around the hangar at the time of discharge. The cause of the discharge is under investigation. The Company has insurance for workers' compensation claims as well as property and equipment losses, including insurance for customer property claims that may result from this incident. The Company also has business interruption insurance for the hangar operations. The Company expects that employee claims, property and equipment damage, customer claims and certain costs of business interruption will be covered by insurance, subject to customary deductibles and policy limits. The extent of the damage, losses, business disruption, and insurance recoveries is being evaluated and cannot be reasonably estimated at this time.

NOTE I—PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS

Defined Benefit and Post-retirement Healthcare Plans

ABX sponsors a qualified defined benefit pension plan for ABX crewmembers and a qualified defined benefit pension plan for a portion of its other ABX employees that meet minimum eligibility requirements. ABX also sponsors non-qualified defined benefit pension plans for certain employees. These non-qualified plans are unfunded. Employees are no longer accruing benefits under any of the defined benefit pension plans. ABX also sponsors a post-retirement healthcare plan for its ABX crewmembers, which is unfunded. Benefits for covered individuals terminate upon reaching age 65 under the post-retirement healthcare plans.

The accounting and valuation for these post-retirement obligations are determined by prescribed accounting and actuarial methods that consider a number of assumptions and estimates. The selection of appropriate assumptions and estimates is significant due to the long time period over which benefits will be accrued and paid. The long term nature of these benefit payouts increases the sensitivity of certain estimates of our post-retirement obligations. The assumptions considered most sensitive in actuarially valuing ABX’s pension obligations and determining related expense amounts are discount rates and expected long term investment returns on plan assets. Additionally, other assumptions concerning retirement ages, mortality and employee turnover also affect the valuations. Actual results and future changes in these assumptions could result in future costs significantly higher than those recorded in our results of operations.

ABX measures plan assets and benefit obligations as of December 31 of each year. Information regarding ABX’s sponsored defined benefit pension plans and post-retirement healthcare plans follow below. The accumulated benefit obligation reflects pension benefit obligations based on the actual earnings and service to-date of current employees.

ABX’s net periodic benefit costs for its defined benefit pension plans and post-retirement healthcare plans are as follows (in thousands):

	Three Months Ended June 30,								Six Months Ended June 30,

During the six month period ending June 30, 2022, the Company contributed $1.1 million to the pension plans. The Company expects to contribute an additional $0.2 million during the remainder of 2022.

NOTE J—INCOME TAXES

The provision for income taxes for interim periods is based on management's best estimate of the effective income tax rate expected to be applicable for the current year, plus any adjustments arising from changes in the estimated amount of taxable income related to prior periods. Income taxes recorded through June 30, 2022 have been estimated utilizing a rate of 23% based upon year-to-date income and projected results for the full year. The recognition of discrete tax items, such as the conversion of employee stock awards, the issuance of stock warrants and other items, have an impact on the effective rate during a period. As a result, the Company's effective tax rate for the first six months of 2022 was 23%. The final effective tax rate for the year 2022 will depend on the actual amount of pre-tax book results by the Company for the full year, the additional conversions of employee stock awards, foreign earnings, executive compensation and other items.

The Company has operating loss carryforwards for U.S. federal income tax purposes. Management expects to utilize the loss carryforwards to offset federal income tax liabilities in the future. Due to the Company's deferred tax assets, including its loss carryforwards, management does not expect to pay federal income taxes until 2025 or later. The Company may, prior to such time, be required to pay some federal tax due to loss carryforward usage limitations and certain state and local income taxes.

NOTE L—STOCK-BASED COMPENSATION

ATSG's Board of Directors has granted stock incentive awards to certain employees and board members pursuant to a long term incentive plan which was approved by its stockholders in May 2005 and in May 2015. Employees have been awarded non-vested stock units with performance conditions, non-vested stock units with market conditions and non-vested time-based restricted stock. The restrictions on the non-vested restricted stock awards lapse at the end of a specified service period, which is typically three years from the date of grant. Restrictions may lapse sooner upon a business combination, death, disability or after an employee qualifies for retirement. The non-vested stock units will be converted into ATSG common stock depending on performance and market conditions at the end of a specified service period, lasting approximately three years. The performance condition awards will be converted into ATSG common stock based on the Company's average return on invested capital during the service period. Similarly, the market condition awards will be converted into ATSG common stock based on the appreciation of the common stock price compared to the NASDAQ Transportation Index. Board members have been granted time-based restricted stock unit awards that vest after a period of twelve months. The Company expects to settle all of the stock unit awards by issuing new shares of ATSG common stock. The table below summarizes stock-based award activity.

	Six Months Ended
	June 30, 2022			June 30, 2021
	Number of Awards	Weighted average grant-date fair value		Number of Awards	Weighted average grant-date fair value

Vested	322,156	$	9.76	357,499	$	9.26

The average grant-date fair value of each performance condition award, non-vested restricted stock award and time-based award granted by the Company in 2022 was $33.84, the fair value of the Company’s stock on the date of grant. The average grant-date fair value of each market condition award granted in 2022 was $46.20. The market condition awards granted in 2022 were valued using a Monte Carlo simulation technique based on daily stock prices over three years and using the following variables:

	2022
Risk-free interest rate	2.5%
Volatility	38.3%

For the six month period ended June 30, 2022 and 2021, the Company recorded expense of $3.9 million and $3.5 million, respectively, for stock incentive awards. At June 30, 2022, there was $12.9 million of unrecognized expense related to the stock incentive awards that is expected to be recognized over a weighted-average period of 1.5 years. As of June 30, 2022, none of the awards were convertible, 322,156 units of the Board members' time-based awards had vested and none of the outstanding shares of the restricted stock had vested. These awards could result in the issuance of up to 1,365,445 shares of ATSG common stock depending on service, performance and market results through December 31, 2024.

NOTE M—COMMON STOCK AND EARNINGS PER SHARE

Earnings per Share

On January 1, 2022 the Company adopted ASU 2020-06 as discussed in Note A. As a result, diluted earnings per share of common stock for the 2022 periods excludes interest charges related to the convertible debt and includes the number of shares that would have been converted at the beginning of the period under the "if-convert" method. The calculation of basic and diluted earnings per share of common stock are as follows (in thousands, except per share amounts):

	Three Months Ending				Six Months Ending
	June 30,				June 30,
	2022		2021		2022		2021
Numerator:
Earnings from continuing operations - basic	$	54,210	$	79,869	$	104,006	$	122,159
Loss (gain) from stock warrants revaluation, net of tax	(107)		(25,816)		(50)		(31,171)
Convertible debt interest charge net of tax	762		—		1,522		—
Earnings from continuing operations - diluted	$	54,865	$	54,053	$	105,478	$	90,988
Denominator:
Weighted-average shares outstanding for basic earnings per share	73,980		68,206		73,934		63,851
Common equivalent shares:
Effect of stock-based compensation awards and warrants	7,358		4,758		7,053		9,998
Effect of convertible debt	8,111		—		8,111		—
Weighted-average shares outstanding assuming dilution	89,449		72,964		89,098		73,849
Basic earnings per share from continuing operations	$	0.73	$	1.17	$	1.41	$	1.91
Diluted earnings per share from continuing operations	$	0.61	0.74		$	1.18	$	1.23

Basic weighted average shares outstanding for purposes of basic earnings per share are less than the shares outstanding due to 375,139 shares and 482,300 shares of restricted stock for 2022 and 2021, respectively, which are accounted for as part of diluted weighted average shares outstanding in diluted earnings per share.

The determination of diluted earnings per share requires the exclusion of the fair value re-measurement of the stock warrants recorded as a liability (see Note C), if such warrants have an anti-dilutive effect on earnings per share. The dilutive effect of the weighted-average diluted shares outstanding is calculated using the treasury method for periods in which equivalent shares have a dilutive effect on earnings per share. Under this method, the number of diluted shares is determined by dividing the assumed proceeds of the warrants recorded as a liability by the average stock price during the period and comparing that amount with the number of corresponding warrants outstanding.

In conjunction with the offering of the Convertible Notes (see note F), the Company also sold warrants for ATSG common stock, subject to customary anti-dilution adjustments. The amount received for these warrants and recorded in Stockholders' Equity in the Company’s consolidated balance sheets was $38.5 million. These warrants may result in 8.1 million additional shares of common stock, if ATSG's traded market price exceeds the strike price which is $41.35 per share and is subject to certain adjustments under the terms of the warrant transactions.

NOTE N—SEGMENT AND REVENUE INFORMATION

The Company operates in two reportable segments - CAM and ACMI Services. The CAM segment consists of the Company's aircraft and engine leasing operations. The ACMI Services segment consists of the Company's airline operations, including CMI agreements as well as ACMI, charter service and passenger service agreements that the Company has with its customers. The Company's aircraft maintenance services, aircraft modification services, ground services and other support services, are not large enough to constitute separate reportable segments and are combined in "All other." Intersegment revenues are valued at arms-length market rates.

Current deferred revenue of $11.1 million and $8.3 million as of June 30, 2022 and December 31, 2021, respectively, for contracts with customers is derived from other activities as described above and CAM non lease revenues. Revenue related to deferred revenue will be recognized based on percentage of completion. Customers are required to pay deposits and may be required to make milestone payments for these services resulting in deferred revenue. Long-term contract assets were $0.0 million and $0.8 million as of June 30, 2022 and December 31, 2021, respectively.

CAM's leases do not contain residual guarantees. Approximately 12% of CAM's leases to external customers contain purchase options at projected market values. As of June 30, 2022, minimum future payments from external customers for leased aircraft and equipment were scheduled to be $140.2 million for the remainder of 2022, $237.4 million, $187.4 million, $175.3 million and $157.2 million for the next 4 years ending December 31, 2026, respectively, and $361.9 million thereafter. CAM's external customer revenues for non-lease activities were $7.4 million and $17.3 million for the three and six month periods ending June 30, 2022, respectively, compared to $4.6 million and $7.0 million during the respective corresponding periods of 2021 for engine services and the sale of spare engine parts.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") has been prepared with reference to the historical financial condition and results of operations of Air Transport Services Group, Inc., and its subsidiaries. Air Transport Services Group, Inc. and its subsidiaries may hereinafter individually and collectively be referred to as "the Company", "we", "our", or "us" from time to time. The MD&A describes the principal factors affecting our results of operations, financial condition, cash flow, liquidity and capital resources. The MD&A should be read in conjunction with the accompanying unaudited condensed consolidated financial statements and related notes prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") contained in this report and the audited consolidated financial statements and related notes prepared in accordance with GAAP contained in our 2021 Form 10-K.

BACKGROUND

We lease aircraft and provide airline operations, aircraft modification and maintenance services, ground services, and other support services to the air transportation and logistics industries. Through ATSG's subsidiaries, we offer a range of complementary services to delivery companies, freight forwarders, e-commerce operators, airlines and government customers. Our principal subsidiaries include our aircraft leasing company (CAM) and three independently certificated airlines (ABX, ATI and OAI).

We have two reportable operating segments:

CAM offers aircraft leasing and related services to external customers and also leases aircraft internally to the Company's airlines. CAM acquires passenger aircraft and manages the modification of the aircraft into freighters. The follow-on aircraft leases normally cover a term of five to ten years. CAM currently leases Boeing 767, 757 and 777 aircraft and aircraft engines.

ACMI Services includes the cargo and passenger transportation operations of our three airlines. Our airlines operate under contracts to provide a combination of aircraft, crews, maintenance, insurance and aviation fuel. Our customers are typically responsible for supplying the necessary aviation fuel and cargo handling services and reimbursing our airline for other operating expenses such as landing fees, ramp expenses, certain aircraft maintenance expenses and fuel procured directly by the airline. Aircraft charter agreements, including those for the DoD, usually require the airline to provide full service, including fuel and other operating expenses for a fixed, all-inclusive price.

Our other business operations, which primarily provide support services to the transportation industry, include providing aircraft maintenance and modification services to customers, cargo load transfer and sorting services as well as related equipment maintenance services. These operations do not constitute separate reportable segments.

At June 30, 2022, we owned 110 Boeing aircraft that were in revenue service. We also owned fourteen Boeing 767-300 aircraft and five Airbus 321-200 aircraft either already undergoing or awaiting induction into the freighter conversion process at June 30, 2022. In addition to these aircraft, we leased four passenger aircraft from third parties and operated seven freighter aircraft provided by customers for whom we provide services under CMI agreements.

Due to the strong demand for medium widebody and narrow body freighters and as part of our continued growth strategy to expand and diversify our fleet, during 2021 we secured additional aircraft conversion slots over the next few years. We continue to work closely with Israel Aerospace Industries and have forged new conversion relationships with Boeing and Elbe Flugzeugwerke (“EFW”). Further, we perform our own conversions of the Airbus A321 aircraft through a joint venture arrangement.

Customers

Our largest customers are ASI, which is a subsidiary of Amazon, the DoD and DHL.

Revenues from our commercial arrangements with ASI comprised approximately 34% and 36% of our consolidated revenues during the six month periods ended June 30, 2022 and 2021, respectively. As of June 30, 2022, we leased 42 Boeing 767 freighter aircraft to ASI with lease expirations between 2023 and 2031 and we operate those aircraft for ASI. The aircraft lease terms typically range from 5 to 10 years. We operate five other Boeing 767 aircraft provided by ASI. We also provide ground services and aircraft maintenance services to ASI.

28

DHL comprised 12% and 13% of our consolidated revenues during the six month periods ended June 30, 2022 and 2021, respectively. As of June 30, 2022, we leased 15 Boeing 767 freighter aircraft to DHL comprised of four Boeing 767-200 aircraft and eleven Boeing 767-300 aircraft, with expirations between 2023 and 2029. Ten of the fifteen Boeing 767 aircraft were being operated by the Company's airlines for DHL. Additionally, we operated two Boeing 767 aircraft that were provided by DHL. In February 2022, the Company and DHL agreed to a six-year extension of its dry leases for five Boeing 767 freighters as well as an extension of the CMI agreement with DHL for ABX to operate aircraft through April 2028. The CMI agreement was subsequently expanded to include two additional 767 freighters.

The DoD comprised 29% and 24% of our consolidated revenues during the six month periods ended June 30, 2022 and 2021 respectively, derived primarily from operating passenger and combi charter flights. We utilize our fleet of fifteen passenger aircraft to operate troop movement flights for the DoD. We also operate our four combi aircraft for the DoD, which are capable of simultaneously carrying cargo and passengers on the main deck. We have been providing services to the DoD since the 1990’s, typically under one year agreements.

RESULTS OF OPERATIONS

Revenue and Earnings Summary

External customer revenues from continuing operations increased by $99.8 million, or 24%, to $509.7 million and $209.6 million, or 27%, to $995.5 million during the first three and six months of 2022 compared to the same periods in 2021. Customer revenues increased during the first six months of 2022 across all lines of business but particularly for contracted airline services, charter flights, aircraft leasing and aviation fuel sales, compared to the previous year's period. Eleven additional aircraft have been placed under customer leases since June 1, 2021. An increase in block hours for DoD troop movements resulted in a significant increase in ACMI Services revenue compared to the prior year's period.

Consolidated net earnings from continuing operations were $54.2 million and $104.0 million for the three and six month periods ended June 30, 2022, respectively, compared to $79.9 million and $122.2 million for the corresponding periods of 2021. The pre-tax earnings from continuing operations were $69.3 million and $134.3 million for the three and six month periods ended June 30, 2022, respectively, compared to $104.2 million and $159.3 million for the corresponding periods of 2021. Earnings were affected by the following specific events and certain adjustments that do not directly reflect our underlying operations among the periods presented.

•Pre-tax earnings from continuing operations included net gains of $6.0 million and $8.7 million for the three and six month periods ended June 30, 2022, respectively for gains related to the repurchase of debt as well as financial instrument valuations, including warrant obligations granted to Amazon. This compares to pre-tax net gains for remeasurement of financial instruments of $35.7 million and $45.2 million for the corresponding periods of 2021.

•Pre-tax earnings from continuing operations were reduced by $5.8 million and $11.6 million for the three and six month periods ended June 30, 2022, respectively, for the amortization of customer incentives given to Amazon in the form of warrants, compared to $5.8 million and $11.5 million for the corresponding periods of 2021.

•Pre-tax earnings from continuing operations included gains of $5.4 million and $10.8 million for the three and six month periods ended June 30, 2022, respectively, for non-service components of retiree benefit plans compared to net gains of $4.5 million and $8.9 million for the corresponding periods of 2021.

•Pre-tax earnings from continuing operations included losses of $3.2 million and $4.6 million for the three and six month periods ended June 30, 2022, respectively, for the Company's share of development costs and expense for a joint venture compared to a net gain of $1.0 million and a net loss of $0.2 million for the corresponding periods of 2021.

•Pre-tax earnings for the three and six month periods ended June 30, 2021 included a charge of $6.5 million to write-off debt issuance costs in conjunction with the restructuring of the Company's debt obligations.

29

•During the three and six months period ended June 30, 2021, the Company recognized $38.3 million and $66.3 million, respectively, of government grants from the CARES Act, PSP Extension Law and the American Rescue Plan.

After removing the effects of these items, adjusted pre-tax earnings from continuing operations, a non-GAAP measure (a definition and reconciliation of adjusted pre-tax earnings from continuing operations follows), were $66.9 million and $131.1 million for the three and six month periods ended June 30, 2022, respectively, compared to $37.1 million and $57.2 million for the corresponding periods of 2021. Improved results were driven by additional aircraft leases to external customers, an increase in the number of freighter aircraft we operate and more passenger block hours for the DoD compared to the previous year's quarter.

A summary of our revenues and pre-tax earnings from continuing operations as well as a reconciliation of adjusted pre-tax earnings from continuing operations to pre-tax earnings from continuing operations is shown below (in thousands):

Adjusted pre-tax earnings from continuing operations, a non-GAAP measure, is pre-tax earnings from continuing operations excluding the following: (i) settlement charges and other non-service components of retiree benefit costs; (ii) gains and losses from financial instrument valuations including warrants issued to Amazon; (iii) customer incentive amortization; and (iv) the start-up costs and expenses of a non-consolidated joint venture. We exclude these items when calculating adjusted pre-tax earnings because they are distinctly different in their predictability or not closely related to our on-going operating activities. We also excluded the recognition of government grants from adjusted earnings to improve comparability between periods. Management uses adjusted pre-tax earnings from continuing operations to compare the performance of core operating results between periods. Presenting this measure provides management and investors with a comparative metric of fundamental operations while highlighting changes to certain items among periods. Adjusted pre-tax earnings from continuing operations should not be considered in isolation or as a substitute for analysis of the Company's results as reported under GAAP.

The Company's earnings were impacted by the fair value re-measurement of the Amazon warrants classified in liabilities at the end of each reporting period, customer incentive amortization and the related income tax effects. The fair value of the warrants issued or issuable to Amazon were recorded as a customer incentive asset and are amortized against revenues over the duration of the aircraft leases. Our accounting for the warrants issued to Amazon has been determined in accordance with the financial reporting guidance for financial instruments. For additional information about the warrants issued to Amazon, see the accompanying notes to the financial statements included in this report.

Aircraft Fleet Summary

Our fleet of cargo and passenger aircraft is summarized in the following table as of June 30, 2022 and December 31, 2021. Our freighters, converted from passenger aircraft, utilize standard shipping containers and can be deployed into regional cargo markets more economically than larger capacity aircraft, newly built freighters or other competing alternatives. At June 30, 2022, we owned fourteen Boeing 767-300 aircraft and five Airbus A321-200 aircraft that were either already undergoing or awaiting induction into the freighter conversion process.

Aircraft fleet activity during the first six months of 2022 is summarized below:

•CAM completed the modification of four Boeing 767-300 freighter aircraft purchased in the previous year. The aircraft are leased to external customers under multi-year leases. Two of the aircraft are being operated by ABX for the customer.

•CAM purchased five Boeing 767-300 passenger aircraft for the purpose of converting the passenger aircraft into a standard freighter configuration. These aircraft are expected to be leased to external customers during 2023.

•OAI returned one Boeing 767-300 passenger aircraft to CAM. CAM expects to modify this aircraft into a standard freighter configuration and lease it to an external customer in 2023.

•CAM purchased four Airbus A321-200 passenger aircraft for the purpose of converting the passenger aircraft into a standard freighter configuration. These aircraft are expected to be leased to external customers during 2022 and 2023.

•ATI began to operate one customer-provided Boeing 767-300 freighter aircraft.

As of June 30, 2022, ABX, ATI and OAI were leasing 21 in-service aircraft internally from CAM for use in ACMI Services. Of CAM's 26 externally leased Boeing 767-200 freighter aircraft, 12 were leased to ASI and operated by ABX or ATI, one was leased to DHL and operated by ABX, three were leased to DHL and were being operated by a DHL-affiliated airline and ten were leased to other external customers. Of the 63 externally leased Boeing 767-300 freighter aircraft, 30 were leased to ASI and operated by ATI, nine were leased to DHL and operated by ABX, two were leased to DHL and are being operated by a DHL-affiliated airline and 22 were leased to other external customers. The carrying values of the total in-service fleet as of June 30, 2022 and December 31, 2021 were $1,731.8 million and $1,693.0 million, respectively.

CAM Segment

CAM added ten Boeing 767-300 freighter aircraft to its portfolio since July 1, 2021. CAM grew its revenues by $21.1 million and $44.7 million during the first three and six months of 2022, respectively, compared to the same periods in 2021.

As of June 30, 2022 and 2021, CAM had 89 and 80 aircraft under lease to external customers, respectively. Revenues from external customers totaled $80.8 million and $157.5 million for the three and six months periods ended June 30, 2022, respectively, compared to $66.7 million and $127.5 million for the corresponding periods of 2021. Since July 1, 2021, CAM placed eleven more Boeing 767-300 aircraft with external customers under long-term leases. Additionally, in October of 2021, CAM began to offer engine power coverage to lessees of CAM's General Electric powered Boeing 767-200 aircraft. Under this service, CAM is responsible for providing and maintaining engines for its lease customers as needed through a pool of engines. Revenues from external customers increased $4.6 million and $10.9 million for the three and six months ended June 30, 2022 compared to the corresponding periods in 2021 for this engine service. CAM's revenues from the Company's airlines totaled $28.9 million and $59.1 million for the three and six month periods ended June 30, 2022, compared to $21.9 million and $44.4 million for the corresponding periods in 2021.

CAM's pre-tax earnings from continuing operations, inclusive of internally allocated interest expense, were $39.6 million and $74.6 million for the three and six month periods ended June 30, 2022 compared to $22.6 million

32

and $44.0 million for the corresponding periods in 2021. Increased pre-tax earnings reflect the ten aircraft placed into service since July 1, 2021 and decreases in internally allocated interest expense of $3.4 million and $5.0 million for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021 due to lower company-wide interest expense and debt. Increased pre-tax earnings were also offset by increased depreciation of $6.4 million and $15.7 million for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021 driven by the addition of aircraft.

In addition to the 14 Boeing 767-300 aircraft and five Airbus A321-200 aircraft which were in the modification process at June 30, 2022, CAM has agreements to purchase eleven more Boeing 767-300 aircraft, four more Airbus A321-200 aircraft and six Airbus A330 aircraft through 2024. CAM's future operating results will depend on its continuing ability to convert passenger aircraft into freighters within planned costs and within the timeframes required by customers. During the second half of 2022, we expect to lease to external customers at least four more newly modified Boeing 767-300 freighters, two newly modified Airbus A321-200 freighters and re-deploy one Boeing 767-200 freighter. CAM's future operating results will also depend on the timing and lease rates under which aircraft are redeployed when leases expire. Additionally, CAM's future operating results from engine power services will depend upon engine cycles operated, the number of engine overhauls and the severity of unscheduled maintenance events.

ACMI Services

Total revenues from ACMI Services increased $74.2 million and $157.2 million during the three and six month periods ended June 30, 2022, respectively, compared with the corresponding periods of 2021. Increased revenues for 2022 reflected a 21% and 30% increase in block hours flown for DoD troop movements particularly to Europe for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods in 2021, as well as eight additional freighter aircraft added to operations compared to the second quarter of 2021, including four more customer-provided aircraft that are not owned by CAM. Revenues also increased due to fuel expenses that are billed through to the DoD and charter customers. The customer fuel portion of ACMI Services revenue increased approximately $23 million and $42 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods in 2021. Overall, customer block hours increased 9% and 15% for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods in 2021, with increases in block hours flown for the DoD, DHL and Amazon. As of June 30, 2022 and 2021, ACMI Services included 84 and 76 in-service aircraft, respectively.

ACMI Services had pre-tax earnings of $21.8 million and $44.0 million for the three and six month periods ended June 30, 2022, respectively, compared to $44.8 million and $66.0 million for the corresponding periods in 2021, inclusive of internally allocated interest expense and the recognition of pandemic-related government grants of $38.3 million and $66.3 million, respectively. Pre-tax earnings, excluding the recognition of government grants, for the three and six month periods ended June 30, 2022 improved $15.3 million and $44.3 million, respectively, compared to the corresponding periods of 2021. Improved earnings were a result of the increased number of aircraft in operations and more block hours flown during the first half of 2022 compared to 2021. While employee salaries and wages, contract labor, fuel and travel expenses all increased relative to the prior year period, this was offset by additional operating volumes which drove earnings higher. Internally allocated interest expense decreased $1.8 million to $2.6 million and decreased $3.0 million to $6.0 million for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021.

Future profitability levels for ACMI Services will depend on a number of factors, including the impact of increasing inflation, COVID-19 outbreaks, customer flight schedules, crew member productivity and pay, rising employee wages and benefits, aircraft maintenance schedules, the severity and frequency of unscheduled maintenance events, the number of aircraft we operate and our ability to pass cost increases on to customers. Recruiting, training and retaining employees and contractors are important factors to our success. Severe disruptions or shortages of qualified employees could have a detrimental impact on our financial results.

33

Other Activities

We provide other support services to our ACMI Services customers and other airlines by leveraging our knowledge and capabilities developed for our own operations over the years. Through our FAA certificated maintenance and repair subsidiaries, we sell aircraft parts and provide aircraft maintenance and modification services. We also provide mail sorting, parcel handling and logistical support to USPS facilities and similar services to certain ASI hub and gateway locations in the U.S. We provide maintenance for ground equipment, facilities and material handling equipment and we resell aviation fuel in Wilmington, Ohio. Additionally, we provide flight training services.

External customer revenues from all other activities increased $11.5 million and $22.4 million in the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. Revenues from fuel sales were up $7.6 million and $13.4 million for the three and six month periods ended June 30, 2022, respectively, while revenues from aircraft maintenance services increased $5.8 million and $9.3 million for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. Revenues from higher margin ground services declined $2.1 million and $0.4 million for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods during the prior year. Pre-tax earnings from other activities decreased by $3.0 million and $1.8 million for the three and six month periods ended June 30, 2022, respectively, compared to the same periods last year. Earnings declined primarily due to the reduction in higher margin ground services revenues.

Expenses from Continuing Operations

Salaries, wages and benefits expense increased $21.3 million, or 15%, and $41.0 million, or 14% during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. The number of total employees has increases by 3% compared to the previous year. In addition, salaries and wages have been impacted by higher wage rates, benefit costs, and more overtime pay.

Depreciation and amortization expense increased $5.7 million and $16.8 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. The increase reflects incremental depreciation for ten additional aircraft as well as additional depreciation expense for engines that are now being serviced and maintained by CAM under engine power coverage arrangements. We expect depreciation expense to increase during future periods in conjunction with our fleet expansion, engine programs and capital spending plans.

Maintenance, materials and repairs expense decreased by $6.5 million and $12.8 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. Maintenance expense for the three and six month periods ended June 30, 2021 included $8.9 million and $18.4 million, respectively, for an engine power-by-the-cycle ("PBC") agreement that expired in September 2021. We are now maintaining these engines through time and material agreements with engine maintenance providers to replace the expired PBC agreement. The decline in PBC expense was offset by increases driven by increased flight operations for the DoD and our customers' express cargo networks. The aircraft maintenance and material expenses can vary among periods due to the number of maintenance events and the scope of airframe checks that are performed.

Fuel expense increased by $36.5 million and $66.4 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. Fuel expense includes the cost of fuel to operate DoD charters, fuel used to position aircraft for service and for maintenance purposes, as well as the cost of fuel sales. Fuel expense increased due to the additional block hours for the DoD and due to increases in the price per gallon of aviation fuel compared to the previous year. Aviation fuel rates increased approximately 60% and 52% per gallon for the three and six month periods ended June 30, 2022, respectively,compared to the corresponding periods of 2021.

Contracted ground and aviation services expense includes navigational services, aircraft and cargo handling services, baggage handling services and other airport services. Contracted ground and aviation services increased $1.4 million and $4.9 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. The increases were driven primarily by the increased flying volume.

Travel expense increased by $10.0 million and $15.8 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. In addition to increased number of crew

34

member and flying volumes, travel expense increased due to significantly higher airfares and hotels rates compared to a year ago.

Landing and ramp expense, which includes the cost of deicing chemicals, increased by $1.1 million and $2.5 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021, driven by increased flying volumes for our customers' express cargo networks.

Other operating expenses increased by $5.6 million and $9.0 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods of 2021. Other operating expenses include professional fees, employee training, utilities, commission expense to our CRAF team for DoD revenues and other expenses.

Operating results included a pre-tax expense credit of $38.3 million and $66.3 million during the three and six month periods ended June 30, 2021, respectively, to recognize grants received from the U.S. government under the CARES Act, PSP Extension Law and the American Rescue Plan. For additional information about these grants, see Note H of the unaudited condensed consolidated financial statements included in this report.

Non-Operating Income, Adjustments and Expenses

Interest expense decreased by $5.6 million and $8.7 million for the three and six months ended June 30, 2022 compared to the corresponding periods for 2021. Interest expense decreased due to lower interest rates on our borrowings under the Senior Credit Agreement and lower average debt balances outstanding during the period.

During the three month period ended June 30, 2022 the company repurchased $120.0 million of its Senior Notes par value in the open market resulting in a net pre-tax gain of $4.5 million, net of fees which was recorded under net gain on financial instruments on the income statement during the corresponding period. The Company recorded unrealized pre-tax gains on financial instrument re-measurements of $6.0 million and $8.7 million for the three and six month period ended June 30, 2022, compared to a pre-tax gain of $35.7 million and $45.2 million for the corresponding periods in 2021. The pre-tax gains for 2022 are primarily a result of the impact of higher market interest rates on the interest rate derivatives that we held. (See Note G for additional information about the interest rate derivatives.). The pre-tax gains for 2021 are primarily a result of re-valuing the stock warrants granted to Amazon. The warrant values generally increase or decrease with corresponding increases or decreases in the ATSG share price during the measurement period. Additionally, the value of certain warrants depends partially on the probability that such warrants will vest upon the execution of aircraft leases. Increases in the probability of warrants vesting results in higher liabilities and losses. In December 2021, most of the outstanding warrants were reclassified from liabilities to paid in capital and are no longer subject to periodic reevaluation. (See Note C for additional information about the Amazon warrants.)

Non service components of retiree benefits resulted in net gains of $5.4 million and $10.8 million for the three and six month periods ended June 30, 2022 compared to net gains of $4.5 million and $8.9 million for the corresponding periods of 2021. The non service component gain and losses of retiree benefits are determined by actuaries and include the amortization of unrecognized gains and losses stemming from changes in assumptions regarding discount rates, expected investment returns and other retirement plan assumptions. Non service components of retiree benefits can vary significantly from one year to the next based on investment results and changes in discount rates used to account for defined benefit retirement plans.

The provision for income taxes for interim periods is based on management's best estimate of the effective income tax rate expected to be applicable for the current year, plus any adjustments arising from changes in the estimated amount of taxable income related to prior periods. Income taxes recorded through June 30, 2022 have been estimated utilizing a 23% rate based upon year-to-date income projected results for the full year. The recognition of discrete tax items such as the conversion of employee stock awards, officer compensation, the issuance of stock warrants and other items have an impact on the effective rate during a period.

The effective rate from continuing operations for the three month period ended June 30, 2022 was 22.6%. The effective tax rate is affected by the discrete tax items in which expense and benefits for tax purposes are different than required by generally accepted accounting principles. The effective tax rate before including the effects of the warrant re-measurement, incentive amortizations and the other adjustments for adjusted pre-tax earnings from continuing operations (see items in the table above) was 23% for both the three and six month periods ended June 30 2022, respectively. The effective tax rate before including the effects of the warrants was 24% and 23% for the three and six month periods ended June 30, 2021, respectively.

Discontinued Operations

The financial results of discontinued operations primarily reflect workers' compensation cost adjustments and other benefits for former employees previously associated with ABX's former hub operations pursuant to which ABX performed package sorting services for DHL. Gains related to the former sorting operations were $0.9 million for the first half of 2022, compared to less than $0.1 million for the corresponding period of 2021. Gains during 2022 and 2021 were primarily a result of reductions in self-insurance reserves for former employee benefit claims.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Net cash generated from operating activities totaled $250.2 million and $307.2 million for the six month periods ended June 30, 2022 and 2021, respectively. Cash flows from operating activities included $83.0 million from government payroll support programs during the first six months of 2021. The decrease in government grant support was offset by improved cash flows generated from additional aircraft leases to customers and increased operating levels under the ACMI Services segment. Cash flows from operations can vary among periods depending on the timing of customer payments received as well as vendor payments we make at the end of a period. Cash outlays for pension contributions were $1.1 million and $1.4 million for the first six months of 2022 and 2021, respectively.

Capital spending levels were primarily the result of aircraft modification costs and the acquisition of aircraft for freighter modification. Cash payments for capital expenditures were $294.2 million and $300.2 million in the first six months of 2022 and 2021, respectively. Capital expenditures in the first half of 2022 included $205.3 million for the acquisition of five Boeing 767-300 aircraft, four Airbus A321-200 aircraft and freighter modification costs; $81.2 million for required heavy maintenance; and $7.7 million for other equipment. Capital expenditures in the first half of 2021 included $200.1 million for the acquisition of twelve Boeing 767-300 aircraft and freighter modification costs; $94.5 million for required heavy maintenance; and $5.6 million for other equipment.

During the first six months of 2022 and 2021, we contributed $16.5 million and $2.5 million, respectively, to our two joint-ventures. Our joint-venture with Precision Aircraft Solutions, LLC, developed a passenger-to-freighter conversion program for Airbus A321-200 aircraft and our joint-venture is with GA Telesis Engine Services, LLC will provide engine tear-down services to harvest and sell engine parts.

Net cash provided by financing activities was $38.0 million for the six months ended June 30, 2022 and net cash provided by financing activities was $40.0 million for the corresponding period in 2021. During the first six months of 2022, we made debt payments of $295.3 million, we drew $450.0 million from the revolving credit facility and we paid $115.2 million to retire Senior Notes. During the first six months of 2021, we made debt principal payments of $1,725.9 million and we drew $1,430.6 million from the revolving credit facility. During the first six months of 2021, we received $207 million in proceeds from the issuance of Additional Senior Notes as well as received $132 million from Amazon for the exercise of warrants for the Company's stock.

Commitments

As of June 30, 2022, the Company had 19 aircraft that were in or awaiting modification to a freighter configuration. Additionally, we placed non-refundable deposits and have agreements to purchase eleven more Boeing 767-300 passenger aircraft, four more Airbus 321-200 and six Airbus A330 aircraft through 2024. We expect to purchase additional aircraft for modification in 2023. The Company outsources a significant portion of the aircraft freighter modification process to non-affiliated third parties. The modification process primarily consists of the installation of a standard cargo door and loading system. We estimate that total capital expenditures for 2022 will be approximately $625 million, of which the majority will be related to aircraft purchases and freighter modifications. Actual capital spending for any future period will be impacted by aircraft acquisitions, maintenance and modification processes.

36

Liquidity

At June 30, 2022, the Company had $47.2 million of cash balances and $269.7 million available from the unused portion of the revolving credit facility under its Senior Credit Agreement as described in Note F of the accompanying financial statements. We expect our operations to continue to generate significant net cash in-flows after deducting required spending of approximately $205 million for heavy maintenance and other sustaining capital expenditures during the year 2022. To expand our fleet, we estimate that capital expenditures for aircraft purchases and freighter modifications will total $420 million for 2022. We believe that the Company's current cash balance, forecasted cash flows provided from its customer leases and operating agreements, combined with borrowing availability under its Senior Credit Agreement, will be sufficient to fund the expansion and maintenance of our fleet while meeting our contractual obligations, other commitments and working capital requirements for at least the next twelve months.

Continued global disruptions in supply chains and labor shortages may delay aircraft modification projects, pushing contractual obligations into later periods and could have an impact on the projected amount of capital expenditures.

CRITICAL ACCOUNTING ESTIMATES

The MD&A and certain other disclosures included elsewhere in this report are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of the financial statements requires us to select appropriate accounting policies and make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingencies. In certain cases, there are alternative policies or estimation techniques which could be applied. On an ongoing basis, we evaluate our selection of policies and the estimation techniques we use, including those related to revenue recognition, post-retirement liabilities, bad debts, self-insurance reserves, valuation of spare parts inventory, useful lives, salvage values and impairment of property and equipment, income taxes, contingencies and litigation. We base our estimates on historical experience, current conditions and on various other assumptions that are believed by management to be reasonable under the circumstances. Those factors form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources, as well as for identifying and assessing our accounting treatment with respect to commitments and contingencies. By their nature, these judgments are subject to uncertainty. Actual results may differ from these estimates under different assumptions or conditions.

For information regarding recently issued accounting pronouncements and the expected impact on our annual statements, see Note A "SUMMARY OF FINANCIAL STATEMENT PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES" in the accompanying notes to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this Form 10-Q. Except as provided in Note A, our critical accounting policies and estimates have not changed materially from those disclosed in our 2021 Form 10-K.

37

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risk for changes in interest rates and changes in the price of jet fuel. The risk associated with jet fuel, however, is largely mitigated by reimbursement through the agreements with its customers.

Market risks have not materially changed from those disclosed in Item 7A of the Company's 2021 Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

As of June 30, 2022, the Company carried out an evaluation, under the supervision and with the participation of the Company's Chief Executive Officer and Chief Financial Officer of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Based upon the evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports filed or submitted by it under the Exchange Act is recorded, processed, summarized and reported within time periods specified in the Securities and Exchange Commission rules and forms and is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Controls

There were no changes in the Company's "internal control over financial reporting" (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during its most recently completed fiscal quarter ended June 30, 2022 that has materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.

38

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are currently a party to legal proceedings in various federal and state jurisdictions arising out of the operation of the Company's business. The amount of alleged liability, if any, from these proceedings cannot be determined with certainty; however, we believe that the Company's ultimate liability, if any, arising from the pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are probable of assertion, taking into account established accruals for estimated liabilities, should not be material to our financial condition or results of operations.

ITEM 1A. RISK FACTORS

The Company faces risks that could adversely affect its condition or results of operations. Many of these risks are disclosed in Item 1A of the Company's 2021 Form 10-K.

In addition to the risks previously disclosed, the recent outbreak of war in Ukraine and the emergence of COVID-19 variants in China and other countries may result in further supply chain disruptions. These matters, coupled with inflationary pressures, could have an impact on overall economic conditions as well as the Company's operations and financial results.

As disclosed in Note H of this report, on August 7, 2022 the fire suppression system discharged at one of our aircraft maintenance hangars in Wilmington, Ohio, impacting employees, three aircraft, and equipment in and around the hangar. We expect that employee claims, property and equipment damage, customer claims and certain costs of business interruption will be covered by insurance, subject to customary deductibles and policy limits. However, our operating results may be impacted by losses and liabilities that are not covered by our insurance. Additionally, property losses will be recognized as they become known to us and related expenses as they are incurred, however insurance proceeds may not be recognized until later periods. As a result, the impact on our earnings may vary from period to period. The timeframes needed to return the hangar and aircraft to operating condition are not determinable at this time. If some or all of these assets remain inoperable for an extended period of time, our operating results could be negatively impacted.

Other risks that are currently unknown to management or are currently considered immaterial or unlikely, could also adversely affect the Company.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On August 5, 2014, the Board of Directors of ATSG authorized the repurchase of up to $50.0 million of ATSG's outstanding common stock. In May 2016, the Board of Directors amended the Company's common stock repurchase program to increase the maximum repurchase amount from $50.0 million to $100.0 million. In February 2018, the Board of Directors increased the repurchase authorization from $100.0 million to $150.0 million (less amounts previously repurchased). The authorization does not require the repurchase of a specific number of shares or establish a time frame for any repurchase and the Board of Directors may terminate the repurchase program at any time. Repurchases may be made from time to time in the open market or in privately negotiated transactions. There is no expiration date for the repurchase program. There were no repurchases made during the second quarter of 2022. As of June 30, 2022, the Company had repurchased 6,592,349 shares and the maximum dollar value of shares that could then be purchased under the program was $61.3 million.

The share repurchase program has been suspended until the CARES Act, PSP Extension Law and American Rescue Plan restrictions on the repurchase of shares have lapsed. For more information, see Note H of the accompanying consolidated financial statements in this report.

Summary of Financial Statement Preparation and Significant Accounting Policies

6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Summary of Financial Statement Preparation and Significant Accounting Policies

SUMMARY OF FINANCIAL STATEMENT PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Air Transport Services Group, Inc. ("ATSG" and, together with its subsidiaries, the "Company," "we," "us," and "our") is a holding company whose subsidiaries lease aircraft and provide contracted airline operations as well as other support services mainly to the air transportation, e-commerce and package delivery industries.

ATSG's leasing subsidiary, Cargo Aircraft Management, Inc. (“CAM”), leases aircraft to each of ATSG's airline subsidiaries as well as to non-affiliated airlines and other lessees. ATSG's airline subsidiaries, ABX Air, Inc. (“ABX”), Air Transport International, Inc. (“ATI”) and Omni Air International, LLC ("OAI") each have the authority, through their separate U.S. Department of Transportation ("DOT") and Federal Aviation Administration ("FAA") certificates, to transport cargo worldwide. The Company provides a combination of aircraft, crews, maintenance and insurance services for its customers' transportation networks through crew, maintenance and insurance ("CMI") agreements and aircraft, crew, maintenance and insurance ("ACMI") agreements and through charter contracts in which aircraft fuel is also included.

In addition to its aircraft leasing and airline services, the Company offers a range of complementary services to delivery companies, freight forwarders, airlines and government customers. These include aircraft maintenance and modification services, aircraft parts supply, equipment maintenance services and load transfer and package sorting services.

Basis of Presentation

The financial statements of the Company are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The accompanying unaudited condensed interim consolidated financial statements are prepared in conformity with GAAP and such principles are applied on a basis consistent with the financial statements reflected in our 2021 Form 10-K. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations promulgated by the SEC related to interim financial statements. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring adjustments, necessary for the fair presentation of the Company's results of operations and financial position for the periods presented. Due to seasonal fluctuations, among other factors common to the air cargo industry, the results of operations for the periods presented are not necessarily indicative of the results of operations to be expected for the entire year or any interim period. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. The accounting estimates reflect the best judgment of management, but actual results could differ materially from those estimates.

The accompanying unaudited condensed consolidated financial statements include the accounts of ATSG and its wholly-owned subsidiaries. Inter-company balances and transactions are eliminated. Investments in affiliates in which the Company has significant influence but does not exercise control are accounted for using the equity method of accounting. Under the equity method, the Company's share of the nonconsolidated affiliate's income or loss is recognized in the consolidated statement of earnings and cumulative post-acquisition changes in the investment are adjusted against the carrying amount of the investment.

Uncertainties

The Company has experienced disruptions to its operations, such as shortages of personnel, parts shortages, maintenance delays, shortages of transportation and hotel accommodations for flight crews, facility closures and other supply chain related issues as a result of the COVID-19 pandemic. The emergence of COVID-19 variants could result in reduced revenues, additional costs and supply chain delays for the Company. The extent of the impact that the coronavirus pandemic will have on our future operations and financial results will depend on future developments, including: the duration, spread, severity and recurrence of the COVID-19 variants; vaccination rates, the effectiveness of vaccines, the duration and scope of government orders and local restrictions as well as the extent of the impact of the pandemic on overall economic conditions.

In February 2022, war started in Ukraine, intensifying geopolitical pressures worldwide. While the Company's operations have not been detrimentally impacted directly, additional supply chain disruptions and inflationary pressures could have an impact on overall economic conditions, as well as the Company's operations and financial results.

Accounting Standards Updates

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-06, "Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"). This new standard removes the separation models for convertible debt with cash conversion or beneficial conversion features. It eliminates the "treasury stock" method for convertible instruments and requires application of the “if-converted” method for certain agreements. The Company adopted ASU 2020-06 on January 1, 2022 using the modified retrospective approach which resulted in the following adjustments:

(in thousands)	December 31, 2021		Adoption of ASU 2020-06		January 1, 2022
Balance Sheet line item:
Principal value	$	(258,750)	$	—	$	(258,750)
Unamortized issuance cost	$	2,889	$	—	$	2,889
Unamortized discount	$	24,215	$	(24,215)	$	—
Convertible Debt	$	(231,646)	$	(24,215)	$	(255,861)
Net deferred tax liability	$	(217,291)	$	5,527	$	(211,764)
Additional paid-in capital	$	(1,074,286)	$	39,559	$	(1,034,727)
Retained earnings	$	(309,430)	$	(20,871)	$	(330,301)

After adopting ASU 2020-06, the Company's Convertible Notes due 2024 (as defined and discussed in Note F) are reflected entirely as a liability as the embedded conversion feature is no longer separately presented within stockholders' equity, which also eliminated the non-cash discount. Accordingly, earnings no longer reflect the discount amortization expense which was $6.4 million of interest expense, net of income taxes during 2021. After giving effect for the adoption, the effective interest rate on the Convertible Notes is 1.5%.

ASU 2020-06 requires the application of the more dilutive if-converted method when calculating the impact of the Convertible Notes on earnings per diluted share. The adoption of ASU 2020-06 does not change the accounting treatment of shares to be delivered by the convertible note hedges (see Note F) purchased by the Company that are designed to offset the shares issued to settle its Convertible Notes, which are anti-dilutive and not reflected in earnings per diluted share.

DoD

The Company is a provider of cargo and passenger airlift services to the U.S. Department of Defense ("DoD"). The DoD awards flights to U.S. certificated airlines through annual contracts and through temporary "expansion" routes.

DHL

The Company has had long-term contracts with DHL Network Operations (USA), Inc. and its affiliates ("DHL") since August 2003. The Company leases Boeing 767 aircraft to DHL under both long-term and short-term lease agreements. Under a separate CMI agreement, the Company operates Boeing 767 aircraft that DHL leases from the Company. Pricing for services provided through the CMI agreement is based on pre-defined fees, scaled for the number of aircraft operated and the number of flight crews provided to DHL for its U.S. network. The Company provides DHL with scheduled maintenance services for aircraft that DHL leases. The Company also provides additional air cargo transportation services for DHL through ACMI agreements in which the Company provides the aircraft, crews, maintenance and insurance under a single contract. As of June 30, 2022, the Company leased 15 Boeing 767 freighter aircraft to DHL comprised of four Boeing 767-200 aircraft and eleven Boeing 767-300 aircraft, with expirations between 2023 and 2029. In February 2022, the Company and DHL agreed to a six-year extension of its dry leases for five Boeing 767 freighters as well as an extension of the CMI agreements to operate aircraft through April 2028.

Amazon

The Company has been providing freighter aircraft, airline operations and services for cargo handling and logistical support for Amazon.com Services, LLC ("ASI"), successor to Amazon.com Services, Inc., a subsidiary of Amazon.com, Inc. ("Amazon") since September 2015. On March 8, 2016, the Company entered into an Air Transportation Services Agreement (the “ATSA”) with ASI, pursuant to which CAM leases Boeing 767 freighter aircraft to ASI. The ATSA also provides for the operation of aircraft by the Company’s airline subsidiaries, and the management of ground services by the Company's subsidiary LGSTX Services, Inc. ("LGSTX"). As of June 30,

2022, the Company leased 30 Boeing 767-300 and 12 Boeing 767-200 freighter aircraft to ASI with lease expirations between 2023 and 2031.

Amazon Investment Agreement

In conjunction with the execution of the ATSA, the Company and Amazon entered into an Investment Agreement on March 8, 2016 (the "2016 Investment Agreement") and a Stockholders Agreement on March 8, 2016. The 2016 Investment Agreement called for the Company to issue warrants in three tranches granting Amazon the right to acquire up to 19.9% of the Company’s outstanding common shares as described below. The first tranche of warrants, issued upon the execution of the 2016 Investment Agreement and all of which are now fully vested, granted Amazon the right to purchase approximately 12.81 million ATSG common shares, with the first 7.69 million common shares vesting upon issuance on March 8, 2016, and the remaining 5.12 million common shares vesting as the Company delivered additional aircraft leased under the ATSA. The second tranche of warrants, which were issued and vested on March 8, 2018, granted Amazon the right to purchase approximately 1.59 million ATSG common shares. The third tranche of warrants vested on September 8, 2020, and granted Amazon the right to purchase an additional 0.5 million ATSG common shares to bring Amazon’s ownership, after the exercise in full of the three tranches of warrants, to 19.9% of the Company’s pre-transaction outstanding common shares measured on a GAAP-diluted basis, adjusted for share issuances and repurchases by the Company following the date of the 2016 Investment Agreement and after giving effect to the warrants granted. The exercise price of the 14.9 million warrants issued under the 2016 Investment Agreement was $9.73 per share, which represents the closing price of ATSG’s common shares on February 9, 2016. Each of the three tranches of warrants were exercisable in accordance with their terms through March 8, 2021 (subject to extension if regulatory approvals, exemptions, authorizations, consents or clearances have not been obtained by such date).

On March 5, 2021, Amazon exercised warrants from the 2016 Investment Agreement for 865,548 shares of the Company's common stock through a cashless exercise by forfeiting 480,047 warrants from the 2016 Investment Agreement as payment. For the cashless exchange, ATSG shares were valued at $27.27 per share, its volume-weighted average price for the previous 30 trading days immediately preceding March 5, 2021. Also on March 5, 2021, Amazon notified the Company of its intent to exercise warrants from the 2016 Investment agreement for 13,562,897 shares of the Company's common stock by paying $132.0 million of cash to the Company. This exercise was contingent upon the approval of the DOT, and the expiration or termination of any applicable waiting period pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976. After receiving all required regulatory approvals and clearances, Amazon remitted the funds to the Company on May 7, 2021, and the Company issued the corresponding shares of common stock, completing the warrant exercise.

On December 22, 2018, the Company announced agreements with ASI to 1) lease and operate ten additional Boeing 767-300 aircraft, 2) extend the term of the 12 Boeing 767-200 aircraft currently leased to ASI by two years to 2023 with an option for three more years, 3) extend the term of the eight Boeing 767-300 aircraft currently leased to ASI by three years to 2026 and 2027 with an option for three more years, and 4) extend the ATSA by five years through March 2026, with an option to extend for an additional three years. The Company leased all ten of the 767-300 aircraft in 2020. In conjunction with the commitment for ten additional 767 aircraft leases, extensions of twenty existing Boeing 767 aircraft leases and the ATSA described above, Amazon and the Company entered into another Investment Agreement on December 20, 2018 (the "2018 Investment Agreement"). Pursuant to the 2018 Investment Agreement, the Company issued Amazon warrants for 14.8 million ATSG common shares. This group of warrants will expire if not exercised within seven years from their issuance date, in December of 2025 (subject to extension if regulatory approvals, exemptions, authorizations, consents or clearances have not been obtained by such date). The warrants have an exercise price of $21.53 per share.

On May 29, 2020, ASI agreed to lease 12 more Boeing 767-300 aircraft from the Company. The first of these leases began in the second quarter of 2020 with the remaining 11 leases commencing in 2021. All 12 of these aircraft leases were for 10-year terms. Pursuant to the 2018 Investment Agreement, as a result of leasing these 12 aircraft, Amazon was issued warrants for 7.0 million common shares, all of which have vested. These warrants will expire if not exercised by December 20, 2025 (subject to extension if regulatory approvals, exemptions, authorizations, consents or clearances have not been obtained by such date). The exercise price of these warrants is $20.40 per share.

Issued and outstanding warrants are summarized below as of June 30, 2022:

		Common Shares in millions
	Exercise price	Vested	Non-Vested	Expiration
2018 Investment Agreement	$21.53	14.8	0.0	December 20, 2025
2018 Investment Agreement	$20.40	7.0	0.0	December 20, 2025

Additionally, Amazon can earn incremental warrants rights of up to 2.9 million common shares under the 2018 Investment Agreement by leasing up to five more cargo aircraft from the Company before January 2026. Incremental warrants granted to Amazon for ASI’s commitment to any such future aircraft leases will have an exercise price based on the volume-weighted average price of the Company's shares during the 30 trading days immediately preceding the contractual commitment for each lease.

For all outstanding warrants vested, Amazon may select a cashless conversion option. Assuming ATSG's stock price at the time of conversion is above the warrant exercise price, Amazon would receive fewer shares in exchange for any warrants exercised under the cashless option by surrendering the number of shares with a market value equal to the exercise price.

The Company’s accounting for the warrants has been determined in accordance with the financial reporting guidance for financial instruments. Warrants classified as liabilities are marked to fair value at the end of each reporting period. The value of warrants is recorded as a customer incentive asset if it is probable of vesting at the time of grant and further changes in the fair value of warrant obligations are recorded to earnings. Upon a warrant vesting event, the customer incentive asset is amortized as a reduction of revenue over the duration of the related revenue contract.

In accordance with the 2016 Investment Agreement, on September 8, 2020, the final number of shares issuable under the third tranche of warrants was determined to be 0.5 million common shares. As a result, under GAAP, the value of the entire warrant grant under the 2016 Investment Agreement was remeasured on September 8, 2020, and its fair value of $221 million was reclassified from balance sheet liabilities to paid-in-capital. In October 2020, upon the execution of the 10th and final aircraft lease of the December 2018 commitment, warrants for 14.8 million shares were remeasured on October 1, 2020, and their fair value of $154 million was reclassified from balance sheet liabilities to paid-in-capital. In December 2021, upon execution of the 12th and final aircraft lease of the May 2020 commitment, warrants for 7.0 million shares were remeasured on December 7, 2021, and their fair value of $82.4 million was reclassified from balance sheet liabilities to paid-in-capital.

As of June 30, 2022 and December 31, 2021, the Company's liabilities reflected warrants from the 2018 Amazon agreements having a fair value of $0.9 million and $0.9 million, respectively. During the three and six months ended June 30 , 2022 the re-measurements of warrants to fair value resulted in a gain of $0.1 million and $0.1 million before the effect of income taxes, respectively, compared to gains of $33.5 million and $40.4 million before the effect of income taxes, respectively, for the corresponding periods of 2021.

The Company's earnings in future periods will be impacted by the re-measurements of warrant fair value, amortizations of the lease incentive asset and the related income tax effects. For income tax calculations, the value and timing of related tax deductions will differ from the guidance described above for financial reporting.

The airline certificates have an indefinite life and therefore are not amortized. The Company amortizes finite-lived intangibles assets, including customer relationship and Supplemental Type Certificates ("STC") intangibles, over 4 to 17 remaining years.

Stock warrants issued to Amazon (see Note C) as an incentive for Amazon subsidiary ASI to lease aircraft from the Company are recorded as a lease incentive asset using their fair value at the time that the lessee has met its performance obligations and if probable of vesting at the time of issuance, and amortized against revenues over the duration of related aircraft leases. The Company's lease incentive granted to the lessee was as follows (in thousands):

The Company has a 49% ownership in a joint-venture agreement with Precision Aircraft Solutions, LLC, to develop a passenger-to-freighter conversion program for Airbus A321-200 aircraft. In April of 2022, the Company acquired a 40% ownership interest in the joint-venture company GA Telesis Engine Services, LLC to provide engine tear-down services to harvest and sell engine parts. The Company accounts for its investment in these joint ventures under the equity method of accounting, in which the carrying value of each investment is reduced for the Company's share of the non-consolidated affiliates' operating results.

The carrying value of the joint ventures totaled $21.6 million and $10.3 million at June 30, 2022 and December 31, 2021, respectively, and are reflected in “Other Assets” in the Company’s consolidated balance sheets. The Company monitors its investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis in accordance with GAAP. If the Company determines that an other-than-temporary decline in value has occurred, it recognizes an impairment loss, which is measured as the difference between the recorded carrying value and the fair value of the investment. The fair value is generally determined using an income approach based on discounted cash flows or using negotiated transaction values.

Fair Value Measurements

FAIR VALUE MEASUREMENTS

The Company’s money market funds and interest rate swaps are reported on the Company’s consolidated balance sheets at fair values based on market values from comparable transactions. The fair value of the Company’s money market funds, Convertible Notes (as defined in Note F), convertible note hedges and interest rate swaps are based on observable inputs (Level 2) from comparable market transactions.

The fair value of the stock warrant obligations to Amazon resulting from aircraft leased to ASI were determined using a Black-Scholes pricing model which considers various assumptions, including the Company’s common stock price, the volatility of the Company’s common stock, the expected dividend yield, exercise price and the risk-free interest rate (Level 2 inputs). The fair value of the stock warrant obligations for unvested stock warrants, conditionally promised to Amazon for the execution of incremental, future aircraft leases, include additional

assumptions including the expected exercise prices and the probabilities that future leases will occur (Level 3 inputs).

The following table reflects assets and liabilities that are measured at fair value on a recurring basis (in thousands):

As a result of lower market interest rates compared to the stated interest rates of the Company’s fixed rate debt obligations, the fair value of the Company’s debt obligations, based on Level 2 observable inputs, was approximately $25.6 million less than the carrying value, which was $1,359.5 million at June 30, 2022. As of December 31, 2021, the fair value of the Company’s debt obligations was approximately $37.1 million less than the carrying value, which was $1,299.4 million. The non-financial assets, including goodwill, intangible assets and property and equipment are measured at fair value on a non-recurring basis.

The Company is party to a syndicated credit agreement (as amended, the "Senior Credit Agreement") which includes the ability to execute term loans and a revolving credit facility. Prior to its amendment on April 6, 2021, the Senior Credit Agreement had a maturity date of November 2024 provided certain liquidity measures are maintained during 2024, an incremental accordion capacity based on debt ratios and a maximum revolver capacity of $600.0 million. The interest rate is a pricing premium added to LIBOR based upon the ratio of the Company's debt to its earnings before interest, taxes, depreciation and amortization expenses ("EBITDA") as defined under the Senior Credit Agreement.

On April 6, 2021, the Company amended the Senior Credit Agreement ("Amended Credit Agreement"). The Amended Credit Agreement: (i) temporarily increased the aggregate amount of the revolving credit facility from $600.0 million to $1 billion, and subsequently decreased the aggregate amount to $800.0 million on April 13, 2021, (ii) permitted increases of the revolving credit facility commitments and/or new tranches of term loans in an aggregate principal amount equal to the sum of $400 million plus the principal amount of indebtedness that could be incurred at the time of the increase that would not cause the Secured Leverage Ratio (as defined in the Amended Credit Agreement) to exceed 3.25 to 1.00 on a pro forma basis, (iii) modified the maturity date of the agreement from November 30, 2024, to April 6, 2026, with such extension of the maturity date being subject to (1) at the election of the lenders, five one-year extensions and (2) an earlier springing maturity date of July 12, 2024, if, on such date, (a) more than $75.0 million in aggregate principal amount of the Convertible Notes (as defined below) remain outstanding and (b) the Company has less than $375.0 million of liquidity at such time, (iv) removed the Collateral to Total Exposure Ratio (as defined in the Senior Credit Agreement) as a financial covenant, and (v) required the Company to repay the balance of all term loans outstanding at the time of the amendment.

On January 28, 2020, CAM completed a debt offering of $500.0 million in senior unsecured notes (together with the "Additional Notes" referred to below, the “Senior Notes”) that were guaranteed by ATSG and certain of its other subsidiaries. The Senior Notes were sold only to qualified institutional buyers in the United States pursuant to Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”), and certain investors pursuant to Regulation S under the Securities Act. The Senior Notes are senior unsecured obligations that bear interest at a fixed rate of 4.75% per year, payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2020. The Senior Notes mature on February 1, 2028. The Senior Notes contain customary events of default and certain covenants which are generally no more restrictive than those set forth in the Senior Credit Agreement. The net proceeds of $495.0 million from the Senior Notes were used to pay down the revolving credit facility. The Senior Notes do not require principal payments until maturity but prepayments are allowed without penalty beginning February 1, 2025.

As of June 30, 2022, the unused revolving credit facility available to the Company at the trailing twelve-month EBITDA level was $269.7 million with additional permitted indebtedness under the Senior Credit Agreement subject to compliance with other covenants.

On April 13, 2021, CAM completed its offering of $200.0 million of additional Senior Notes that were guaranteed by ATSG and certain of its subsidiaries. The additional Senior Notes are fully fungible with the original Senior Notes, treated as a single class for all purposes under the indenture governing all the Senior Notes with the same terms (other than issue date and issue price). The proceeds of $205.5 million, net of scheduled interest

payable, were used, in conjunction with draws from the revolving credit facility to repay the unsubordinated term loans. Upon retirement of the unsubordinated term loans, the Company expensed debt issuance costs of $6.5 million related to the unsubordinated term loans.

During the three month period ended June 30, 2022, the Company repurchased Senior Notes having a principal value of $120.0 million in the open market at a 5.5% reducing the Senior Notes carrying value to $577.9 million. The Company recognized a net pre-tax gain of $4.5 million, net of fees which was recorded under net gain of financial instruments on the income statement during the corresponding period.

The balance of the Senior Notes is net of debt issuance costs of $5.9 million and $7.8 million as of June 30, 2022 and December 31, 2021, respectively. Under the terms of the Senior Credit Agreement, interest rates are adjusted at least quarterly based on the Company's EBITDA, its outstanding debt level and prevailing LIBOR or prime rates. At the Company's debt-to-EBITDA ratio as of June 30, 2022, the LIBOR based financing for the revolving credit facility bear variable interest rates of 2.62%.

The Senior Credit Agreement is collateralized by certain of the Company's Boeing 777, 767 and 757 aircraft. Under the terms of the Senior Credit Agreement, the Company is required to maintain certain collateral coverage ratios set forth in the Senior Credit Agreement. The Senior Credit Agreement limits the amount of dividends the Company can pay and the amount of common stock it can repurchase to $100.0 million during any calendar year, provided the Company's total debt to EBITDA ratio is under 3.50 to 1.0 and the secured debt to EBITDA ratio is under 3.0 to 1.0, after giving effect to the dividend or repurchase. The Senior Credit Agreement contains covenants, including a maximum permitted total EBITDA to debt ratio, a fixed charge covenant ratio requirement, and limitations on certain additional indebtedness and guarantees of indebtedness. The Senior Credit Agreement stipulates events of default, including unspecified events that may have material adverse effects on the Company. If an event of default occurs, the Company may be forced to repay, renegotiate or replace the Senior Credit Agreement.

In September 2017, ATSG issued $258.8 million aggregate principal amount of 1.125% convertible senior notes due 2024 ("Convertible Notes") in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Convertible Notes bear interest at a rate of 1.125% per year payable semi-annually in arrears on April 15 and October 15 each year, beginning April 15, 2018. The Convertible Notes mature on October 15, 2024, unless repurchased or converted in accordance with their terms prior to such date. The Convertible Notes are unsecured indebtedness, subordinated to the Company's existing and future secured indebtedness and other liabilities, including trade payables.

Conversion of the Convertible Notes can only occur upon satisfaction of certain conditions and during certain periods, beginning any calendar quarter commencing after December 31, 2017, until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon the occurrence of certain fundamental changes, holders of the Convertible Notes can require the Company to repurchase their notes at the cash repurchase price equal to the principal amount of the notes, plus any accrued and unpaid interest. The Company has the right to settle the Convertible Notes in cash, the Company’s common shares or a combination of cash and the Company’s common shares, at the Company’s election. The initial conversion rate is 31.35 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $31.90 per common share). If a “make-whole fundamental change” (as defined in the offering circular with the Convertible Notes) occurs, the Company will, in certain circumstances, increase the conversion rate for a specified period of time.

The conversion feature of the Convertible Notes required bifurcation from the principal amount under the applicable accounting guidance. On January 1, 2022 the Company adopted ASU 2020-06 using the modified retrospective approach as discussed in Note A which recombined the value of the previously bifurcated embedded feature with the convertible note and eliminated the discount. The carrying value of the Company's convertible debt is shown below (in thousands):

	June 30,		December 31,
	2022		2021
Principal value, Convertible Notes, due 2024	$	258,750	$	258,750
Unamortized issuance costs	(2,373)		(2,889)
Unamortized discount	—		(24,215)
Convertible debt	$	256,377	$	231,646

In conjunction with the Convertible Notes, the Company purchased convertible note hedges under privately negotiated transactions for $56.1 million, having the same number of the Company's shares of common stock (8.1 million shares) and the same strike price ($31.90) that underlie the Convertible Notes. The convertible note hedges are expected to reduce the potential equity dilution with respect to the Company's common stock and/or offset any cash payments in excess of the principal amount due, as the case may be, upon conversion of the Convertible Notes. The Company's current intent and policy is to settle all Note conversions through a combination settlement which satisfies the principal amount of the Convertible Notes outstanding with cash.

COMMITMENTS AND CONTINGENCIES

Payroll Support Programs

During 2020, two of the Company's airline subsidiaries, OAI and ATI, received government funds totaling $75.8 million pursuant to payroll support program agreements under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). In February 2021, OAI was approved for $37.4 million of additional non-repayable government funds pursuant to a payroll support program agreement under the Consolidated Appropriations Act, 2021 (the “PSP Extension Law”). This grant was subsequently increased by $5.6 million. Further, in April 2021, OAI was approved for $40.0 million of additional non-repayable government funds pursuant to a payroll support program agreement under the American Rescue Plan Act of 2021 (the "American Rescue Plan").

The three programs are structured in a substantially similar manner. These grants are not required to be repaid if the Company complies with the provisions of the payroll support program agreements under the CARES Act, the PSP Extension Law and the American Rescue Plan. The grants are recognized over the periods in which the Company recognizes the related expenses for which the grants are intended to compensate. The Company recognized the grants as contra-expense during the periods in which passenger flight operations and combi flight operations levels were expected to be negatively impacted by the pandemic. During the three month and six month periods ended June 30 2021, the Company recognized $38.3 million and $66.3 million of the grants, respectively. The Company recognized all of the CARES Act funds by the end of 2021.

In conjunction with the payroll support program agreements under the CARES Act, OAI and ATI agreed on behalf of themselves and ABX to refrain from conducting involuntary furloughs or reducing employee rates of pay or benefits through September 30, 2020. Thereafter, OAI agreed as a condition of receiving grants under the PSP Extension Law and the American Rescue Plan to refrain from conducting involuntary furloughs or reducing employee rates of pay or benefits through March 31, 2021, and September 30, 2021, respectively. Under the CARES Act, OAI and ATI agreed to limit, on behalf of themselves and certain affiliates, executive compensation through March 24, 2022; maintain certain air transportation service through March 1, 2022 as may be required by the DOT pursuant to its authority under the CARES Act; and maintain certain internal controls and records relating to the funds and comply with certain reporting requirements. OAI further agreed as a condition of receiving grants under the PSP Extension Law and thereafter the American Rescue Plan, to limit executive compensation through October 1, 2022 and April 1, 2023, respectively. In addition, the Company may not pay dividends or repurchase its shares through September 30, 2022.

Lease Commitments

The Company leases property, aircraft, aircraft engines and other types of equipment under operating leases. The Company's airlines operate seven freighter aircraft provided by customers and four passenger aircraft leased from external companies. Property leases include hangars, warehouses, offices and other space at certain airports with fixed rent payments and lease terms ranging from one month to six years. The Company is obligated to pay the lessor for maintenance, real estate taxes, insurance and other operating expenses on certain property leases. These expenses are variable and are not included in the measurement of the lease asset or lease liability. These expenses are recognized as variable lease expense when incurred and are not material. Equipment leases include ground support and industrial equipment as well as computer hardware with fixed rent payments and terms of one month to five years.

The Company records the initial right-to-use asset and lease liability at the present value of lease payments scheduled during the lease term. For the six month period ending June 30, 2022 and 2021, non-cash transactions to recognize right-to-use assets and corresponding liabilities for new leases were $12.7 million and $5.9 million, respectively. Unless the rate implicit in the lease is readily determinable, the Company discounts the lease payments using an estimated incremental borrowing rate at the time of lease commencement. The Company estimates the incremental borrowing rate based on the information available at the lease commencement date, including the rate the Company could borrow for a similar amount, over a similar lease term with similar collateral. The Company's weighted-average discount rate for operating leases at June 30, 2022 was 2.3% compared to 2.4% at December 31, 2021. Leases often include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. Although not material, the amount of such options is reflected below in the maturity of operating lease liabilities table. Lease expense is recognized on a straight-line basis over the lease term. The weighted-average remaining lease term is 3.5 years and 3.8 years as of June 30, 2022 and December 31, 2021, respectively.

For the six month periods ending June 30, 2022 and 2021, cash payments against operating lease liabilities were $11.0 million and $10.7 million, respectively. As of June 30, 2022, the maturities of operating lease liabilities are as follows (in thousands):

	Operating Leases
Remaining 2022	$	11,280
2023	20,381

Less: amount representing interest	(2,543)
Present value of future minimum lease payments	64,802

Long-term lease obligation	$	44,305

Purchase Commitments

The Company has agreements with vendors for the conversion of Boeing 767-300, Airbus A321 and Airbus A330 passenger aircraft into a standard configured freighter aircraft. The conversions primarily consist of the installation of a standard cargo door and loading system. As of June 30, 2022, the Company owned fourteen Boeing 767-300 aircraft and five Airbus A321-200 aircraft that were in or awaiting the modification process. As of June 30, 2022, the Company has agreements to purchase eleven more Boeing 767-300 passenger aircraft, four more Airbus A321 passenger aircraft and six Airbus A330 passenger aircraft through 2024. As of June 30, 2022, the Company's commitments to acquire and complete the conversion of these aircraft totaled $707.0 million, including estimated payments of $415.4 million through 2023 and the remaining payments through 2026. Actual conversion payments will be based on the achievement of process milestones.

Guarantees and Indemnifications

Certain leases and agreements of the Company contain guarantees and indemnification obligations to the lessor, or one or more other parties, that are considered reasonable and customary (e.g. use, tax and environmental indemnifications), the terms of which range in duration and are often limited. Such indemnification obligations may continue after expiration of the respective lease or agreement.

Other

In addition to the foregoing matters, the Company is also a party to legal proceedings in various federal and state jurisdictions from time to time arising out of the operation of the Company's business. The amount of alleged liability, if any, from these proceedings cannot be determined with certainty; however, the Company believes that its ultimate liability, if any, arising from pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are probable of assertion, taking into account established accruals for estimated liabilities, should not be material to our financial condition or results of operations.

Employees Under Collective Bargaining Agreements

As of June 30, 2022, the flight crewmember employees of ABX, ATI and OAI and flight attendant employees of ATI and OAI were represented by the labor unions listed below:

Airline	Labor Agreement Unit	Percentage of the Company’s Employees
ABX	International Brotherhood of Teamsters	5.8%
ATI	Air Line Pilots Association	9.7%
OAI	International Brotherhood of Teamsters	6.1%
ATI	Association of Flight Attendants	0.6%
OAI	Association of Flight Attendants	5.8%

The labor agreements with ATI 's flight crew members and Omni's flight crew members are amendable at this time. Under the Railway Labor Act, as amended, airline labor agreements do not expire, so the existing contract remains in effect throughout the negotiation process.

Subsequent Event

On August 7, 2022 the fire suppression system discharged at one of the Company's aircraft maintenance hangars in Wilmington, Ohio. The event impacted employees, three aircraft and equipment in and around the hangar at the time of discharge. The cause of the discharge is under investigation. The Company has insurance for workers' compensation claims as well as property and equipment losses, including insurance for customer property claims that may result from this incident. The Company also has business interruption insurance for the hangar operations. The Company expects that employee claims, property and equipment damage, customer claims and certain costs of business interruption will be covered by insurance, subject to customary deductibles and policy limits. The extent of the damage, losses, business disruption, and insurance recoveries is being evaluated and cannot be reasonably estimated at this time.

Retirement Benefits [Abstract]

Pension and Other Post-Retirement Benefit Plans

PENSION AND OTHER POST-RETIREMENT BENEFIT PLANS

Defined Benefit and Post-retirement Healthcare Plans

ABX sponsors a qualified defined benefit pension plan for ABX crewmembers and a qualified defined benefit pension plan for a portion of its other ABX employees that meet minimum eligibility requirements. ABX also sponsors non-qualified defined benefit pension plans for certain employees. These non-qualified plans are unfunded. Employees are no longer accruing benefits under any of the defined benefit pension plans. ABX also sponsors a post-retirement healthcare plan for its ABX crewmembers, which is unfunded. Benefits for covered individuals terminate upon reaching age 65 under the post-retirement healthcare plans.

The accounting and valuation for these post-retirement obligations are determined by prescribed accounting and actuarial methods that consider a number of assumptions and estimates. The selection of appropriate assumptions and estimates is significant due to the long time period over which benefits will be accrued and paid. The long term nature of these benefit payouts increases the sensitivity of certain estimates of our post-retirement obligations. The assumptions considered most sensitive in actuarially valuing ABX’s pension obligations and determining related expense amounts are discount rates and expected long term investment returns on plan assets. Additionally, other assumptions concerning retirement ages, mortality and employee turnover also affect the valuations. Actual results and future changes in these assumptions could result in future costs significantly higher than those recorded in our results of operations.

ABX measures plan assets and benefit obligations as of December 31 of each year. Information regarding ABX’s sponsored defined benefit pension plans and post-retirement healthcare plans follow below. The accumulated benefit obligation reflects pension benefit obligations based on the actual earnings and service to-date of current employees.

ABX’s net periodic benefit costs for its defined benefit pension plans and post-retirement healthcare plans are as follows (in thousands):

Income Taxes	6 Months Ended
	Jun. 30, 2022
Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXESThe provision for income taxes for interim periods is based on management's best estimate of the effective income tax rate expected to be applicable for the current year, plus any adjustments arising from changes in the estimated amount of taxable income related to prior periods. Income taxes recorded through June 30, 2022 have been estimated utilizing a rate of 23% based upon year-to-date income and projected results for the full year. The recognition of discrete tax items, such as the conversion of employee stock awards, the issuance of stock warrants and other items, have an impact on the effective rate during a period. As a result, the Company's effective tax rate for the first six months of 2022 was 23%. The final effective tax rate for the year 2022 will depend on the actual amount of pre-tax book results by the Company for the full year, the additional conversions of employee stock awards, foreign earnings, executive compensation and other items. The Company has operating loss carryforwards for U.S. federal income tax purposes. Management expects to utilize the loss carryforwards to offset federal income tax liabilities in the future. Due to the Company's deferred tax assets, including its loss carryforwards, management does not expect to pay federal income taxes until 2025 or later. The Company may, prior to such time, be required to pay some federal tax due to loss carryforward usage limitations and certain state and local income taxes

The outstanding interest rate swaps are not designated as hedges for accounting purposes. The effects of future fluctuations in LIBOR interest rates on derivatives held by the Company will result in the recording of unrealized gains and losses into the statement of operations. The Company recorded net gains on derivatives of $1.4 million and $4.1 million for the three and six month periods ending June 30, 2022, respectively, compared to net gains of $2.3 million and $4.8 million for the corresponding periods of 2021. The liability for outstanding derivatives is recorded in other liabilities and in accrued expenses.

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

STOCK-BASED COMPENSATION

ATSG's Board of Directors has granted stock incentive awards to certain employees and board members pursuant to a long term incentive plan which was approved by its stockholders in May 2005 and in May 2015. Employees have been awarded non-vested stock units with performance conditions, non-vested stock units with market conditions and non-vested time-based restricted stock. The restrictions on the non-vested restricted stock awards lapse at the end of a specified service period, which is typically three years from the date of grant. Restrictions may lapse sooner upon a business combination, death, disability or after an employee qualifies for retirement. The non-vested stock units will be converted into ATSG common stock depending on performance and market conditions at the end of a specified service period, lasting approximately three years. The performance condition awards will be converted into ATSG common stock based on the Company's average return on invested capital during the service period. Similarly, the market condition awards will be converted into ATSG common stock based on the appreciation of the common stock price compared to the NASDAQ Transportation Index. Board members have been granted time-based restricted stock unit awards that vest after a period of twelve months. The Company expects to settle all of the stock unit awards by issuing new shares of ATSG common stock. The table below summarizes stock-based award activity.

The average grant-date fair value of each performance condition award, non-vested restricted stock award and time-based award granted by the Company in 2022 was $33.84, the fair value of the Company’s stock on the date of grant. The average grant-date fair value of each market condition award granted in 2022 was $46.20. The market condition awards granted in 2022 were valued using a Monte Carlo simulation technique based on daily stock prices over three years and using the following variables:

	2022
Risk-free interest rate	2.5%
Volatility	38.3%

For the six month period ended June 30, 2022 and 2021, the Company recorded expense of $3.9 million and $3.5 million, respectively, for stock incentive awards. At June 30, 2022, there was $12.9 million of unrecognized expense related to the stock incentive awards that is expected to be recognized over a weighted-average period of 1.5 years. As of June 30, 2022, none of the awards were convertible, 322,156 units of the Board members' time-based awards had vested and none of the outstanding shares of the restricted stock had vested. These awards could result in the issuance of up to 1,365,445 shares of ATSG common stock depending on service, performance and market results through December 31, 2024.

Earnings Per Share

COMMON STOCK AND EARNINGS PER SHARE

Earnings per Share

On January 1, 2022 the Company adopted ASU 2020-06 as discussed in Note A. As a result, diluted earnings per share of common stock for the 2022 periods excludes interest charges related to the convertible debt and includes the number of shares that would have been converted at the beginning of the period under the "if-convert" method. The calculation of basic and diluted earnings per share of common stock are as follows (in thousands, except per share amounts):

	Three Months Ending				Six Months Ending
	June 30,				June 30,
	2022		2021		2022		2021
Numerator:

Earnings from continuing operations - diluted	$	54,865	$	54,053	$	105,478	$	90,988
Denominator:
Weighted-average shares outstanding for basic earnings per share	73,980		68,206		73,934		63,851
Common equivalent shares:
Effect of stock-based compensation awards and warrants	7,358		4,758		7,053		9,998
Effect of convertible debt	8,111		—		8,111		—
Weighted-average shares outstanding assuming dilution	89,449		72,964		89,098		73,849
Basic earnings per share from continuing operations	$	0.73	$	1.17	$	1.41	$	1.91
Diluted earnings per share from continuing operations	$	0.61	0.74		$	1.18	$	1.23

Basic weighted average shares outstanding for purposes of basic earnings per share are less than the shares outstanding due to 375,139 shares and 482,300 shares of restricted stock for 2022 and 2021, respectively, which are accounted for as part of diluted weighted average shares outstanding in diluted earnings per share.

The determination of diluted earnings per share requires the exclusion of the fair value re-measurement of the stock warrants recorded as a liability (see Note C), if such warrants have an anti-dilutive effect on earnings per share. The dilutive effect of the weighted-average diluted shares outstanding is calculated using the treasury method for periods in which equivalent shares have a dilutive effect on earnings per share. Under this method, the number of diluted shares is determined by dividing the assumed proceeds of the warrants recorded as a liability by the average stock price during the period and comparing that amount with the number of corresponding warrants outstanding.

In conjunction with the offering of the Convertible Notes (see note F), the Company also sold warrants for ATSG common stock, subject to customary anti-dilution adjustments. The amount received for these warrants and recorded in Stockholders' Equity in the Company’s consolidated balance sheets was $38.5 million. These warrants may result in 8.1 million additional shares of common stock, if ATSG's traded market price exceeds the strike price which is $41.35 per share and is subject to certain adjustments under the terms of the warrant transactions.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The financial statements of the Company are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The accompanying unaudited condensed interim consolidated financial statements are prepared in conformity with GAAP and such principles are applied on a basis consistent with the financial statements reflected in our 2021 Form 10-K. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations promulgated by the SEC related to interim financial statements. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring adjustments, necessary for the fair presentation of the Company's results of operations and financial position for the periods presented. Due to seasonal fluctuations, among other factors common to the air cargo industry, the results of operations for the periods presented are not necessarily indicative of the results of operations to be expected for the entire year or any interim period. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. The accounting estimates reflect the best judgment of management, but actual results could differ materially from those estimates.

The accompanying unaudited condensed consolidated financial statements include the accounts of ATSG and its wholly-owned subsidiaries. Inter-company balances and transactions are eliminated. Investments in affiliates in which the Company has significant influence but does not exercise control are accounted for using the equity method of accounting. Under the equity method, the Company's share of the nonconsolidated affiliate's income or loss is recognized in the consolidated statement of earnings and cumulative post-acquisition changes in the investment are adjusted against the carrying amount of the investment.

Use of Estimates

Uncertainties

The Company has experienced disruptions to its operations, such as shortages of personnel, parts shortages, maintenance delays, shortages of transportation and hotel accommodations for flight crews, facility closures and other supply chain related issues as a result of the COVID-19 pandemic. The emergence of COVID-19 variants could result in reduced revenues, additional costs and supply chain delays for the Company. The extent of the impact that the coronavirus pandemic will have on our future operations and financial results will depend on future developments, including: the duration, spread, severity and recurrence of the COVID-19 variants; vaccination rates, the effectiveness of vaccines, the duration and scope of government orders and local restrictions as well as the extent of the impact of the pandemic on overall economic conditions.

In February 2022, war started in Ukraine, intensifying geopolitical pressures worldwide. While the Company's operations have not been detrimentally impacted directly, additional supply chain disruptions and inflationary pressures could have an impact on overall economic conditions, as well as the Company's operations and financial results.

New Accounting Pronouncements

Accounting Standards Updates

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-06, "Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"). This new standard removes the separation models for convertible debt with cash conversion or beneficial conversion features. It eliminates the "treasury stock" method for convertible instruments and requires application of the “if-converted” method for certain agreements. The Company adopted ASU 2020-06 on January 1, 2022 using the modified retrospective approach which resulted in the following adjustments:

(in thousands)	December 31, 2021		Adoption of ASU 2020-06		January 1, 2022
Balance Sheet line item:
Principal value	$	(258,750)	$	—	$	(258,750)
Unamortized issuance cost	$	2,889	$	—	$	2,889
Unamortized discount	$	24,215	$	(24,215)	$	—
Convertible Debt	$	(231,646)	$	(24,215)	$	(255,861)
Net deferred tax liability	$	(217,291)	$	5,527	$	(211,764)
Additional paid-in capital	$	(1,074,286)	$	39,559	$	(1,034,727)
Retained earnings	$	(309,430)	$	(20,871)	$	(330,301)

After adopting ASU 2020-06, the Company's Convertible Notes due 2024 (as defined and discussed in Note F) are reflected entirely as a liability as the embedded conversion feature is no longer separately presented within stockholders' equity, which also eliminated the non-cash discount. Accordingly, earnings no longer reflect the discount amortization expense which was $6.4 million of interest expense, net of income taxes during 2021. After giving effect for the adoption, the effective interest rate on the Convertible Notes is 1.5%.

ASU 2020-06 requires the application of the more dilutive if-converted method when calculating the impact of the Convertible Notes on earnings per diluted share. The adoption of ASU 2020-06 does not change the accounting treatment of shares to be delivered by the convertible note hedges (see Note F) purchased by the Company that are designed to offset the shares issued to settle its Convertible Notes, which are anti-dilutive and not reflected in earnings per diluted share.
