FILINGS WITH THE SECURITIES AND EXCHANGE COMMISSION

The financial information, including the financial statements, included in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2023 (the "Form 10-Q") should be read in conjunction with the audited consolidated financial statements and notes thereto of Air Transport Services Group, Inc. ("ATSG") included in ATSG's Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission ("SEC") on March 1, 2023 ("2022 Form 10-K").

The SEC maintains an Internet site that contains reports, proxy and information statements and other information regarding ATSG at www.sec.gov. Additionally, ATSG's filings with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to these reports, are available free of charge from our website at www.atsginc.com as soon as reasonably practicable after filing with the SEC.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The Private Securities Litigation Reform Act of 1995 (“Act”) provides a safe harbor for forward-looking statements to encourage companies to provide prospective information, so long as those statements are identified as forward-looking and are accompanied by meaningful cautionary statements identifying important factors that could cause actual results to differ materially from those discussed in the statements. The Company wishes to take advantage of the safe harbor provisions of the Act.

This Form 10-Q, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in Part I, Item 2, contains forward-looking statements, within the meaning of Act. Except for historical information contained in this Form 10-Q, the matters discussed herein contain forward-looking statements that involve risks and uncertainties. Such statements are provided under the “safe harbor” protection of the Act.

Forward-looking statements include, but are not limited to, statements regarding anticipated operating results, prospects and levels of assets under management, technological developments, economic trends, expected transactions and similar matters. The words “may,” “believe,” “expect,” “anticipate,” “target,” “goal,” “project,” “estimate,” “guidance,” “forecast,” “outlook,” “will,” “continue,” “likely,” “should,” “hope,” “seek,” “plan,” “intend” and variations of such words and similar expressions identify forward-looking statements. Similarly, descriptions of the Company’s objectives, strategies, plans, goals or targets are also forward-looking statements. Forward-looking statements are susceptible to a number of risks, uncertainties and other factors. While the Company believes that the assumptions underlying its forward-looking statements are reasonable, investors are cautioned that any of the assumptions could prove to be inaccurate and, accordingly, the Company’s actual results and experiences could differ materially from the anticipated results or other expectations expressed in its forward-looking statements.

A number of important factors could cause the Company’s actual results to differ materially from those indicated by such forward-looking statements. These factors include, but are not limited to: (i) unplanned changes in the market demand for its assets and services, including the loss of customers or a reduction in the level of services it performs for customers; (ii) its operating airlines’ ability to maintain on-time service and control costs; (iii) the cost and timing with respect to which it is able to purchase and modify aircraft to a cargo configuration; (iv) fluctuations in the Company’s traded share price and in interest rates, which may result in mark-to-market charges on certain financial instruments; (v) the number, timing, and scheduled routes of its aircraft deployments to customers; (vi) its ability to remain in compliance with key agreements with customers, lenders and government agencies; (vii) the impact of current supply chain constraints both within and outside the Unites States, which may be more severe or persist longer than it currently expects; (viii) the impact of a competitive labor market, which could restrict its ability to fill key positions; and (ix) changes in general economic and/or industry-specific conditions, including inflation. Other factors that could cause the Company’s actual results to differ materially from those indicated by such forward-looking statements are discussed in “Risk Factors” in Item 1A to the 2022 Form 10-K and are contained from time to time in ATSG’s other filings with the SEC, including its annual reports on Form 10-K and quarterly reports on Form 10-Q.

Readers should carefully review this Form 10-Q and should not place undue reliance on the Company’s forward-looking statements. The forward-looking statements were based on information, plans and estimates as of the date of

---

this Form 10-Q. New risks and uncertainties arise from time to time, and factors that the Company currently deems immaterial may become material, and it is impossible for the Company to predict these events or how they may affect it. Except as may be required by applicable law, the Company undertakes no obligation to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events or other changes. The Company does not endorse any projections regarding future performance that may be made by third parties.

CERTAIN DEFINED TERMS IN THIS FORM 10-Q

ATSG and its subsidiaries may sometimes be referred to in this Form 10-Q individually or collectively as the “Company,” “we,” “our,” or “us.” ATSG’s outstanding common stock, par value $0.01 per share, is referred to in this Form 10-Q as “common stock,” “common shares,” “stock” or “shares.”

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

Nature of Operations

ATSG 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.

The Company's leasing subsidiary, Cargo Aircraft Management, Inc. (“CAM”), leases aircraft to each of the Company's airlines as well as to non-affiliated airlines and other lessees. The Company's airlines, 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 network 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. The Company's subsidiary, LGSTX Services, Inc. ("LGSTX") provides for the management of aircraft ground services.

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 2022 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 the 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 non-consolidated 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.

Accounting Standards Updates

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 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.

Carrying value as of June 30, 2023						$	9,000					$	82,560					$	91,560

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.com, Inc. (“Amazon”) (see Note C) as an incentive for a subsidiary of Amazon 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 amortized against revenues over the duration of related aircraft leases. The Company's lease incentive granted to the lessee was as follows (in thousands):

						Lease
						Incentive
Carrying value as of December 31, 2022						$	79,650
Amortization						(10,541)
Carrying value as of June 30, 2023						$	69,109

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 $21.0 million and $18.9 million at June 30, 2023 and December 31, 2022, 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 DoD. The Company's airlines are eligible to bid for military charter operations for passenger and cargo transportation through contracts awarded by the DoD. The airlines draw from the Company's fleet of Boeing 757 combi, Boeing 777 passenger, Boeing 767 passenger and Boeing 767 freighter aircraft for the DoD operations. 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, 2023, the Company leased 12 Boeing 767 freighter aircraft to DHL comprised of one Boeing 767-200 aircraft and eleven Boeing 767-300 aircraft, with expirations between 2023 and 2028. Further, beginning in third quarter of 2022, the Company began to operate four Boeing 767 aircraft provided by DHL under an additional CMI agreement which currently runs through August of 2027.

Amazon

The Company has been providing freighter aircraft, airline operations and services for cargo handling and logistical support for ASI, successor to Amazon.com Services, Inc., a subsidiary of 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 LGSTX. As of June 30, 2023, the Company leased 38 Boeing 767 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 (as amended, 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 ATSG'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 ATSG'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 ATSG's common stock, completing the warrant exercise.

On December 22, 2018, the Company announced agreements with Amazon to 1) lease and operate ten additional Boeing 767-300 aircraft for ASI, 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 to Amazon warrants for 14.8 million ATSG common shares of ATSG. 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 twelve more Boeing 767-300 aircraft from the Company. The first of these leases began in the second quarter of 2020 with the remaining eleven delivered in 2021. All twelve of these aircraft leases were for ten-year terms. Pursuant to the 2018 Investment Agreement, as a result of leasing 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, 2023:

												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 additional warrants for 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 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 resumed repurchases of its own shares during October 2022 in conjunction with the expiration of certain government restrictions stemming from the Coronavirus Aid, Relief and Economic Security Act. As the Company repurchases its own shares, Amazon has the option to sell shares of ATSG's common stock to the Company to maintain its ownership percentage of less than 19.9% of the Company's outstanding shares pursuant to the terms of the 2016 Investment Agreement, as amended. On October 7, 2022, Amazon sold 250,000 shares of ATSG's common stock back to the Company for cash of $5.9 million, pursuant to the terms of the 2016 Investment Agreement, as amended on March 5, 2021. Also on December 16, 2022, Amazon sold 260,000 shares of ATSG's common stock back to the Company for cash of $7.0 million. These transactions resulted in Amazon maintaining its ownership percentage of less than 19.9% of ATSG's outstanding common shares at the time.

The Company’s accounting for the warrants and the sale option have been determined in accordance with the financial reporting guidance for financial instruments. Warrants and the sale option are classified as liabilities and 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.

As of June 30, 2023 and December 31, 2022, the Company's liabilities reflected warrants and Amazon sale options from the 2018 Amazon agreements having a fair value of $1.8 million and $0.7 million, respectively. During the three month and six month periods ended June 30, 2023, the re-measurements of warrants and sale options to fair value resulted in net non-operating losses of $0.3 million and $1.1 million before the effect of income taxes, respectively, compared to net non-operating gains of $0.1 million and $0.1 million in the corresponding periods in 2022.

The Company's earnings in future periods will be impacted by the re-measurements of warrant fair value, sale option 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 ATSG's common stock price, the volatility of ATSG'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 granted

---

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 fair value of the sale option for Amazon to sell back shares to the Company under certain conditions was determined based on future share repurchase scenarios. Judgement was applied to determine the number of shares that would be repurchased by the Company at a certain price and the probability of each scenario. There is uncertainty regarding the future stock price at the time of repurchase which affects the magnitude of the gain or loss recognized (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 higher 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 $89.8 million less than the carrying value, which was $1,514.7 million at June 30, 2023. As of December 31, 2022, the fair value of the Company’s debt obligations was approximately $48.3 million less than the carrying value, which was $1,464.9 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 a 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. On October 19, 2022, the Company amended the Senior Credit Agreement. This amendment i) increased the aggregate amount of the revolving credit facility from $800 million to $1 billion, ii) extended the maturity date of the agreement from April 6, 2026 to October 19, 2027, iii) replaced LIBOR with SOFR as an interest rate benchmark, iv) reduced the collateral to outstanding loan ratio to 1.15:1.00 from 1.25:1:00, v) permits cash dividends and share repurchases provided the secured leverage ratio is less than 3.00 to 1.00 and the total leverage ratio is less than 3.50 to 1.00, and removed the annual limitation on cash dividends and share repurchases which was $100 million.

The interest rate is a pricing premium added to SOFR 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. As of June 30, 2023, the unused revolving credit facility available to the Company at the trailing twelve-month EBITDA level was $418.6 million, and additional permitted indebtedness under the Senior Credit Agreement subject to compliance with other covenants.

On March 1, 2023, the Company entered into an additional revolving credit facility domiciled in Ireland (the "Irish Facility"). The terms and conditions of the Irish Facility are similar to the Senior Credit Agreement in the U.S. The Irish Facility has a maximum capacity of $100.0 million, including a $7.5 million letter of credit sub-facility, and has the ability to be upsized using the same accordion feature that is present in the Senior Credit Agreement. The maturity date of the Irish Facility is the same as the Senior Credit Agreement.

---

On January 28, 2020, CAM completed a debt offering of $500.0 million in senior unsecured notes (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 will 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. On April 13, 2021, the Company, through a subsidiary, completed its offering of $200.0 million of additional notes ("Additional Notes") under the existing Senior Notes. The Additional Notes are fully fungible with the Senior Notes, treated as a single class for all purposes under the indenture governing the existing notes with the same terms as those of the existing notes (other than issue date and issue price).

During 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 $578.0 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 $4.8 million and $5.4 million as of June 30, 2023 and December 31, 2022, 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 SOFR or prime rates. At the Company's debt-to-EBITDA ratio as of June 30, 2023, the SOFR-based financing for the revolving credit facility bears a variable interest rate of 6.51%. The Senior Notes do not require principal payments until maturity but prepayments are allowed without penalty beginning February 1, 2025.

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 times and the secured debt to EBITDA ratio is under 3.0 times, 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 on 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 and thereafter, 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 for a cash repurchase price equal to the principal amount of the notes, plus any accrued and unpaid interest.

ATSG has the right to settle the Convertible Notes in cash, ATSG common shares or a combination of cash and ATSG common shares. The initial conversion rate is 31.3475 common shares 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, ATSG will, in certain circumstances, increase the conversion rate for a specified period of time.

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 ATSG common shares (8.1 million shares) and 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 ATSG's common shares, 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.

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, 2023						December 31, 2022
Principal value, Convertible Senior Notes, due 2024						$	258,750					$	258,750
Unamortized issuance costs						(1,312)						(1,847)
Convertible debt						$	257,438					$	256,903

In conjunction with the offering of the Convertible Notes, the Company also sold warrants to the convertible note hedge counterparties in separate, privately negotiated warrant transactions at a higher strike price and for the same number of the Company’s common shares, 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 could result in 8.1 million additional shares of ATSG's common stock if the Company'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. The warrants could have a dilutive effect on the computation of earnings per share to the extent the average traded market price of the Company's common shares for reporting periods exceeds the strike price.

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 (in thousands):

									June 30, 2023												December 31, 2022
Expiration Date			Stated Interest Rate						Notional Amount						Market Value (Liability)						Notional Amount						Market Value (Liability)
March 31, 2023			2.425		%				—						—						125,625						677
March 31, 2026			3.793		%				50,000						830						—						—

June 30, 2026			4.185		%				50,000						153						—						—

The outstanding interest rate swaps are not designated as hedges for accounting purposes. The effects of future fluctuations in SOFR 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 pre-tax gains on derivatives of $2.1 million and $1.1 million for the three and six month periods ended June 30, 2023, respectively, compared to gains of $1.4 million and $4.1 million for the corresponding periods in 2022. The liability for outstanding derivatives is recorded in other liabilities and in accrued expenses.

NOTE H—COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company leases property, aircraft, aircraft engines and other types of equipment under operating leases. The Company's airlines operate fifteen 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 nine 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 months ended June 30, 2023 and 2022, non-cash transactions to recognize right-to-use assets and corresponding liabilities for new leases were $1.0 million and $12.7 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, 2023 and December 31, 2022 was 3.5% and 3.2%, respectively. 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. Our weighted-average remaining lease term is 4.1 years and 4.3 years as of June 30, 2023 and December 31, 2022, respectively.

For the six months ended June 30, 2023 and 2022, cash payments against operating lease liabilities were $13.2 million and $11.0 million, respectively. As of June 30, 2023, the maturities of operating lease liabilities are as follows (in thousands):

						Operating Leases
2023						$	12,754
2024						19,998
2025						12,931
2026						8,482

Less: amount representing interest						(5,222)
Present value of future minimum lease payments						61,803
Less: current obligations under leases						21,771
Long-term lease obligation						$	40,032

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, 2023, the Company owned twenty Boeing 767-300 aircraft and nine Airbus A321-200 aircraft that were in or awaiting the modification process. As of June 30, 2023, the Company has agreements to purchase nine more Boeing 767-300 passenger aircraft and seven Airbus A330-300 passenger aircraft through 2024. As of June 30, 2023, the Company's commitments to acquire and convert aircraft totaled $576.6 million, including estimated payments of $150.0 million through the remainder of

---

2023, with the remaining payments due from 2024 through 2026. Actual conversion payments will be based on the achievement of progress milestones.

Hangar Foam Discharge

On August 7, 2022 the fire suppression system at one of the Company's aircraft maintenance hangars in Wilmington, Ohio malfunctioned and discharged a significant amount of expansive foam. The event impacted employees, three aircraft and equipment in and around the hangar at the time of discharge. The hangar resumed operations after approximately three weeks while the cause of the incident was investigated and the hangar was cleaned and restored. While one aircraft was returned to service, the timeframes needed to return two of the aircraft and related engines to operating condition are not known at this time. The Company maintains insurance for employee claims, remediation expenses, property and equipment damage, customer claims and business interruption subject to customary deductibles and policy limits. The anticipated insurance recoveries related to clean-up expenses, remediation, part repairs and property damages are recorded when receipt is probable. Insurance recoveries in excess of the net book value of the damaged operating assets and for business interruption claims are recorded when all contingencies related to the claim have been resolved.

For the three and six month period ended June 30, 2023 the Company recognized charges in operating income for property damages and repairs, net of recorded insurance recoveries of less than $0.1 million. Through June 30, 2023, the Company has incurred $6.8 million for losses resulting from the incident and recorded $5.8 million for insurance recoveries. Insurance receivables were $3.3 million and $2.8 million as of June 30, 2023 and December 31, 2022, respectively.

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, 2023, 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			5.2%

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 major portion of its 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-sponsored defined benefit pension plans and post-retirement healthcare plans follows 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 for the three and six month periods ended June 30, 2023 and 2022, are as follows (in thousands):

			Three Months Ended June 30,																								Six Months Ended June 30,
			Pension Plans												Post-Retirement Healthcare Plan												Pension Plans												Post-Retirement Healthcare Plan

During the six month period ending June 30, 2023, the Company made contributions to the pension plans of $1.2 million . The Company expects to contribute an additional $0.1 million during the remainder of 2023.

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, 2023 have been estimated utilizing a rate of 23.9% 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 of these differences in which expenses and benefits for tax purposes are different than required by GAAP, the Company's effective tax rate for the six months ended June 30, 2023 was 23.8%. The final effective tax rate for the year 2023 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, stock warrant valuations, 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, cash payments for income taxes will be limited through 2025. The Company is required to pay some federal tax due to loss carryforward usage limitations and certain state and local income taxes.

NOTE K—ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

NOTE L—STOCK-BASED COMPENSATION

ATSG's Board of Directors has granted stock-based incentive awards to certain employees and directors pursuant to a long-term incentive plan which was approved by the Company's stockholders in May 2005 and in May 2015. Employees have been awarded non-vested restricted stock, non-vested stock units with performance conditions, and non-vested stock units with market conditions. 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 grant date. The non-vested stock units will be converted into a number of ATSG common shares depending on the satisfaction of the performance conditions or market conditions at the end of a specified service period, which is typically three years from the grant date. The performance condition awards will be converted into a number of ATSG common shares based on the Company's average return on invested capital during the service period. Similarly, the market condition awards will be converted into a number of common shares depending on the appreciation of ATSG common shares compared to the Nasdaq Transportation Index. Directors have been granted time-based awards that vest after a period of twelve months. Under each of the stock-based incentive awards, the restrictions may lapse sooner than the stated settlement period upon (1) the participant's death or disability, (2) an employee participant's qualification for retirement or (3) a change in control, in the case of an employee participant under the 2015 long-term incentive plan, or a business combination, in the case of a director participant under the 2005 or 2015 long-term incentive plan. The Company expects to settle all of the stock unit awards by issuing new ATSG common shares. The table below summarizes award activity for the six months ended June 30, 2023 and 2022:

			Six Months Ended
			June 30, 2023												June 30, 2022
			Number of Awards						Weighted average grant-date fair value						Number of Awards						Weighted average grant-date fair value
Outstanding at beginning of period			929,205						$	21.83					978,188						$	17.49

Forfeited			(9,200)						25.35						(9,000)						26.06
Outstanding at end of period			1,303,975						$	21.70					1,079,095						$	21.34
Vested			346,565						$	9.78					322,156						$	9.76

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 2023 was $20.78, 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 2023 was $23.28. The market condition awards granted in 2023 were valued using a Monte Carlo simulation technique based on daily stock prices over three years and using the following variables:

			2023
Risk-free interest rate			3.7%
Volatility			37.1%

For the six months ended June 30, 2023 and 2022, the Company recorded expense of $4.2 million and $3.9 million respectively, for stock-based incentive awards. At June 30, 2023, there was $16.8 million of unrecognized expense related to the stock-based incentive awards that is expected to be recognized over a weighted-average period of 1.59 years. As of June 30, 2023, none of the awards were convertible, 346,565 units of the directors' 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 a maximum number of 1,660,525 additional outstanding shares of ATSG's common stock depending on service, performance and market results through December 31, 2025.

NOTE M—COMMON STOCK AND EARNINGS PER SHARE

Earnings per Share

The calculation of basic and diluted earnings per common share is as follows (in thousands, except per share amounts):

			Three Months Ended												Six Months Ended
			June 30,												June 30,
			2023						2022						2023						2022
Numerator:
Earnings from continuing operations - basic			$	38,022					$	54,210					$	58,163					$	104,006
Gain from stock warrants revaluation, net of tax			$	—					$	(107)					$	(148)					$	(50)
Convertible debt interest charge, net of tax			$	780					$	762					$	1,556					$	1,522
Earnings from continuing operations - diluted			$	38,802					$	54,865					$	59,571					$	105,478
Denominator:
Weighted-average shares outstanding for basic earnings per share			70,722						73,980						71,259						73,934
Common equivalent shares:
Effect of stock-based compensation awards and warrants			682						7,358						1,906						7,053
Effect of convertible debt			8,111						8,111						8,111						8,111
Weighted-average shares outstanding assuming dilution			79,515						89,449						81,276						89,098
Basic earnings per share from continuing operations			$	0.54					$	0.73					$	0.82					$	1.41
Diluted earnings per share from continuing operations			$	0.49					$	0.61					$	0.73					$	1.18

Basic weighted average shares outstanding for purposes of basic earnings per share are less than the shares outstanding due to 482,010 shares and 375,139 shares of restricted stock for 2023 and 2022, 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 reportable segments and are combined in All other. Intersegment revenues are valued at arms-length market rates.

During the three and six month periods ending June 30, 2023, the Company recognized $12.2 million and $6.5 million, respectively, of non-lease revenue that was reported as deferred revenue at the beginning of the applicable period, compared to $3.3 million and $3.9 million, respectively, for the comparable periods in the prior year. Current deferred revenue of $9.9 million and $17.0 million as of June 30, 2023 and December 31, 2022, respectively, for contracts with customers is derived from other activities as described above. 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 $0.7 million as of June 30, 2023 compared to $0.0 million as of December 31, 2022. Cash will be collected over the term of the multi-year agreement based on number cycles per period while revenue is recognized as parts are provided for engine maintenance services. This may result in a contract asset or liability based on the timing of engine maintenance services.

CAM's leases do not contain residual guarantees. Approximately 10% of CAM's leases to external customers contain purchase options at projected market values. As of June 30, 2023, minimum future payments from external customers for leased aircraft and equipment were scheduled to be $141.4 million for the remainder of 2023, and $247.3 million, $227.2 million, $203.5 million and $172.3 million, respectively, for each of the next four years ending December 31, 2027 and $313.9 million thereafter. CAM's external customer revenues for non-lease activities were $8.7 million and $15.4 million for the three and six month period ended June 30, 2023 for engine services and the sale of spare engine parts compared to $7.4 million and $17.3 million, respectively, during the comparable periods in the prior year.

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

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 ATSG and its subsidiaries. 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 Form 10-Q and the audited consolidated financial statements and related notes prepared in accordance with GAAP contained in our 2022 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 our 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.

We also 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 provide aircraft maintenance and modification services and sell aircraft parts. We also provide mail sorting, parcel handling and logistical support to United States Postal Service (USPS) facilities and similar services to certain ASI hub and gateway locations in the United States. 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. The operations described in this paragraph do not constitute a separate reportable segment and are reported in “All other.”

At June 30, 2023, we owned 106 Boeing aircraft that were in revenue service. We also owned twenty Boeing 767-300 aircraft and nine Airbus 321-200 aircraft either undergoing or awaiting induction into the freighter conversion process at June 30, 2023. In addition to these aircraft, we leased four passenger aircraft from third parties and operated fifteen freighter aircraft provided by customers for whom we provide services under CMI agreements.

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 34% of our consolidated revenues during the six month periods ended June 30, 2023 and 2022, respectively. As of June 30, 2023, we leased 38 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 nine other Boeing 767 aircraft provided by ASI. We also provide ground services and aircraft maintenance services to ASI.

DHL comprised 13% and 12% of our consolidated revenues during the six month periods ended June 30, 2023 and 2022, respectively. As of June 30, 2023, we leased 12 Boeing 767 freighter aircraft to DHL comprised of one Boeing 767-200 aircraft and eleven Boeing 767-300 aircraft, with expirations between 2023 and 2029. Ten of the

---

12 Boeing 767 aircraft were being operated by our airlines for DHL. Additionally, we operated six 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 expanded to include two additional 767 freighters.

The DoD comprised 30% and 29% of our consolidated revenues during the six month periods ended June 30, 2023 and 2022 respectively, derived primarily from operating passenger and combi charter flights. We utilize our fleet of fourteen 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 $19.7 million, or 4%, to $529.3 million and $34.9 million, or 4%, to $1,030.4 million during the three and six month periods ended June 30, 2023, respectively, compared to the same periods in 2022. Customer revenues increased during the first six months of 2023 for aircraft contracted airline services, charter flights, aircraft leasing and aircraft maintenance services, compared to the previous year periods.

The consolidated earnings from continuing operations were $38.0 million and $58.2 million for the three and six month periods ended June 30, 2023, respectively, compared to $54.2 million and $104.0 million for the corresponding periods in the prior year. The pre-tax earnings from continuing operations were $49.7 million and $76.3 million for three and six month periods ended June 30, 2023, respectively, compared to $69.3 million and $134.3 million for the corresponding periods in the prior year. Earnings were affected by the following events and items that do not directly reflect our underlying operations among the periods presented. Pre-tax earnings from continuing operations:

•included gains of $1.8 million and $0.1 million for the three and six month periods ended June 30, 2023, respectively, for financial instrument valuations, including instruments granted to Amazon compared to net gains of $6.0 million and $8.7 million for the same periods in the prior year.

•were also reduced by $4.7 million and $10.5 million for the three and six month periods ended June 30, 2023, respectively, for the amortization of customer lease incentives given to Amazon in the form of warrants compared to $5.8 million and $11.6 million for the same periods in the prior year.

•included losses of $3.2 million and $6.4 million for the three and six month periods ended June 30, 2023, respectively, for settlement charges, curtailments and other non-service components of retiree benefit plans compared to gains of $5.4 million and $10.8 million for the same periods in the prior year.

•included losses of $2.1 million and $2.5 million for the three and six month periods ended June 30, 2023, respectively, for our share of joint venture results, including engineering costs for the development of an aircraft modification for the Airbus A321 compared to losses of $3.2 million and $4.6 million for the same periods in the prior year.

•included gains of less than $0.1 million and losses of $0.1 million for the three and six month periods ended June 30, 2023, respectively, for net related insurance recoveries for the costs which occurred as a direct result of a foam release after a hangar's fire suppression system malfunctioned during 2022.

After removing the effects of these events and items, adjusted pre-tax earnings from continuing operations, a non-GAAP financial measure (see the reconciliation of adjusted pre-tax earnings from continuing operations to pre-tax earnings from continuing operations in the following table), were $57.9 million and $95.7 million for three and six month periods ended June 30, 2023, respectively, compared to $66.9 million and $131.1 million for the corresponding periods in 2022.

Adjusted pre-tax earnings from continuing operations for the three months ended June 30, 2023 decreased $9.0 million primarily due to reduced number of aircraft leases. The decrease in the six month period ended June 30, 2023 of $35.4 million is primarily due to a lower level of passenger operations within ACMI Services in the first quarter and fewer aircraft under lease with customers.

Adjusted Pre-Tax Earnings from Continuing Operations (non-GAAP)			$	57,940					$	66,893					$	95,736					$	131,095

We define adjusted pre-tax earnings from continuing operations, a non-GAAP financial measure, as 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 for the fair value re-measurement of financial instruments including warrants issued to Amazon; (iii) customer lease incentive amortization; (iv) gains and losses from non-consolidated joint ventures; and (v) charges related to the discharge of a fire suppression system in the Company's aircraft hangar, net of related insurance recoveries. We exclude these items from pre-tax earnings from continuing operations because they are distinctly different in their predictability or not closely related to our on-going operating activities. Management uses adjusted pre-tax earnings from continuing operations to compare the performance of core operating results between periods. Presenting this non-GAAP financial measure provides management and investors with a comparative metric of fundamental operations while highlighting changes to certain items among periods. Adjusted results should not be considered in isolation or as a substitute for analysis of the Company's results as calculated and reported under GAAP.

Aircraft Fleet Summary

Our fleet of cargo and passenger aircraft is summarized in the following table as of June 30, 2023, and December 31, 2022. 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, 2023, we owned 20 Boeing 767-300 aircraft and nine Airbus A321-200 aircraft that were undergoing or awaiting induction into the freighter conversion process.

Aircraft fleet activity during the first six months of 2023 is listed below:

•CAM completed the modification of three Boeing 767-300 freighter aircraft purchased in the previous year. The aircraft are leased to external customers under multi-year leases.

•CAM purchased eight 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 2024.

•CAM purchased two 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 an external customer during 2023 and 2024.

•External customers returned eight Boeing 767-200 freighter aircraft to CAM. Two of these aircraft are being staged for future deployment. The other six have currently been removed from service and their parts and engines will be used to support the fleet, re-leased to customers or possibly sold.

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

As of June 30, 2023, ABX, ATI and OAI were leasing 20 in-service aircraft internally from CAM for use in ACMI Services. Of CAM's 18 externally leased Boeing 767-200 freighter aircraft, eight were leased to ASI and operated by ABX or ATI, one was leased to DHL and operated by ABX and nine were leased to other external customers. Of the 68 externally leased Boeing 767-300 freighter aircraft, 30 were leased to ASI and operated by ABX or ATI, nine were leased to DHL and operated by ABX, two were leased to DHL and were being operated by a DHL-affiliated airline and 27 were leased to other external customers. The carrying values of the total in-service fleet as of June 30, 2023 and December 31 2022 were $1,736.1 million and $1,741.7 million, respectively.

---

Additionally, we owned several Boeing 767-200 airframes that have been removed from service and which are being used to support our in-service Boeing fleet with engines and aircraft parts.

CAM

CAM's revenues from external customers totaled $84.2 million and $167.4 million for the three and six month periods ended June 30, 2023, respectively, compared to $80.8 million and $157.5 million for the same periods in the prior year. CAM's revenues from our airlines totaled $27.2 million and $56.1 million during the three and six month periods ended June 30, 2023 compared to $28.9 million and $59.1 million for the same periods in the prior year. CAM's aircraft leasing and related services revenues, which exclude customer lease incentive amortization, increased $0.6 million and $5.7 million for the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods in 2022, as a result of new aircraft leases in 2023 and 2022, offset by the return of Boeing 767-200 freighter aircraft from lease. Since July 1, 2022, CAM added five Boeing 767-300 freighter aircraft to its portfolio and placed these five aircraft with external customers under long-term leases. Additionally, since July 1, 2022, ten 767-200 freighters were returned from lease. CAM is currently prepping two of these 767-200 freighters for re-lease, and has re-leased another 767-200 freighter to an external customer. CAM's revenues from its 767-200 engine power program has decreased $1.9 million and $2.9 million for the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022, due to the reduction in leased 767-200 aircraft.

CAM's pre-tax earnings, inclusive of internally allocated interest expense, were $31.0 million and $65.2 million for the three and six months ended June 30, 2023 compared to $39.6 million and $74.6 million for the same periods in the prior year. Pre-tax earnings reflects four fewer aircraft, netting additional 767-300 leases with 767-200 freighter returns since July 1, 2022. Additionally, depreciation expense increased $1.7 million and $5.8 million for the three and six month periods ended June 30, 2023, respectively, primarily due to the new aircraft placed into service. Reduced earnings also included $4.7 million and $7.0 million more internally allocated interest expense due to higher company-wide interest expense.

As of June 30, 2023, CAM's fleet included 20 Boeing 767-300 aircraft and nine Airbus A321-200 aircraft which were in or awaiting the modification process. Six of these aircraft have already begun long-term leases with external customers in the third quarter with ten more scheduled to begin long-term leases with external customers later in 2023, 12 in 2024 and one in 2025. During the remainder of 2023, three more Boeing 767-200 aircraft leases are scheduled to expire and may be offered for resale or re-leased.

CAM expects to begin the passenger-to-freighter conversion of Airbus A330 aircraft in 2023 and expects to begin leasing the Airbus A330 freighter aircraft in 2024. CAM has agreements to purchase nine more Boeing 767-300 aircraft and seven Airbus A330-300 aircraft during 2023 and 2024. Eight of these aircraft are scheduled to be leased with external customers in 2024, six in 2025 and two in 2026. If future market conditions affect the demand for modified aircraft or the projected returns on our fleet expansion, we have the flexibility to reduce planned growth investments in 2024 and beyond.

CAM's operating results will depend on its continuing ability to convert passenger aircraft into freighters within planned costs and within the time frames required by customers. CAM's future operating results will also depend on lease rates under which aircraft are redeployed. The U.S. FAA has certified the design of the modified Airbus A321 that CAM utilizes to convert the passenger aircraft to a freighter. Our joint venture is working with regulators in Europe on remaining issues to certify the Airbus A321 to operate there. Prolonged delays in that certification process could impact our Airbus 321 aircraft fleet expansion in future years.

ACMI Services

Total revenues from ACMI Services increased $18.7 million and $22.7 million compared to 2022 for the three and six month period ended June 30, 2023 to $366.2 million and $700.3 million, respectively, while block hours flown for customers increased 1% for the same comparison periods. The increase in revenues reflects additional aircraft operated and block hours flown for our customers' delivery networks compared to the prior year periods. During the three and six month periods ended June 30, 2023, block hours flown for our customers' delivery networks increased 1% and 3%, respectively, including more U.S. continental. block hours and fewer inter-continental block hours compared for the corresponding periods in 2022. We are operating three more freighter aircraft in ACMI Services since July 1, 2022. Block hours for DoD and other passenger services during the three and six month periods ended June 30, 2023, including operation of Boeing 757 combi aircraft, declined 2% and 9%,

---

respectively, compared to the corresponding periods of 2022. Declines in revenue generated from lower passenger block hours were offset by increased revenues during 2023 for higher prices of aviation fuel for DoD flying which is included in our ACMI Services revenues.

ACMI Services had pre-tax earnings of $24.1 million and $21.6 million during the three and six month periods ended June 30, 2023, respectively, compared to pre-tax earnings of $21.8 million and $44.0 million for the corresponding periods of 2022 inclusive of internally allocated interest expense. ACMI Services was impacted by additional internally allocated interest expense of $2.4 million and $4.0 million for the three and six month period ended June 30, 2023, respectively, compared to the corresponding periods in 2022 due to higher interest rates and debt balances in 2023. The decline in year-to-date earnings during 2023 also included reduced passenger services revenues and higher operating expenses experienced in the first quarter of 2023. During the second quarter of 2023, passenger services revenue rebounded driven by additional charter and nonmilitary flights in which certain operating expenses are contractually passed through to the customer.

Maintaining profitability in ACMI Services will depend on a number of factors, including the impact of inflation on operating expenses, customer billing rates, customer flight schedules, crewmember productivity and pay, employee attrition, employee benefits, aircraft maintenance schedules and the number of aircraft we operate. Recruiting, training and retaining employees and contractors are important factors to our success. If we experience a shortage of qualified employees, ACMI Services' financial results could be detrimentally impacted.

Other Activities

External customer revenues from all other activities decreased $2.4 million and increased $2.3 million for the three and six month periods ended June 30, 2023, respectively, to $79.0 million and $162.8 million compared to the corresponding periods of 2022. During 2023, increases in aircraft maintenance services were offset by lower fuel revenues and one fewer ground hub service location compared to 2022. Aviation fuel revenues can fluctuate significantly among periods due volatility of fuel prices. Pre-tax losses from other activities were $1.3 million and $0.6 million for the three and six month periods ended June 30, 2023 compared to pre-tax earnings of $0.2 million and $1.7 million for the same periods in the prior year. The decrease in earnings reflected higher labor and administrative costs.

Expenses from Continuing Operations

Salaries, wages and benefits expense increased $7.7 million or 5% and $22.6 million or 7% during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022. These expenses have been impacted by higher wage rates, increased personnel, including more pilots and benefit costs, higher employee attrition rates and more overtime pay. Inflationary pressures and employee attrition may continue to impact wages in the future.

Depreciation and amortization expense increased $1.3 million and $4.0 million during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022. The increase reflects incremental depreciation for five newly converted aircraft added to its operating fleet since July 1, 2022. Since July 1, 2022, airframes for seven Boeing 767-200 aircraft have become fully depreciated. We expect depreciation expense to continue to increase during future periods in conjunction with our fleet expansion, engine programs and capital spending plans.

Maintenance, materials and repairs expense increased by $11.0 million or 28% and $19.2 million or 25% during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022. This expense line includes the cost of materials and repairs to maintain aircraft and engines, as well as similar costs for providing maintenance services to customers. The increase reflects an increase in scheduled airframe maintenance and part repairs. 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 decreased by $5.8 million and increased by $0.6 million during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022. Fuel expense includes the cost of fuel to operate DoD flights, fuel used to position aircraft for service and for maintenance purposes, as well as the cost of fuel we resell to customers at the airport in Wilmington, Ohio. For the six month period ended June 30 2023, total fuel expense increased slightly compared to the prior year period reflecting a higher cost per gallon for DoD required fuel, largely offset by a reduction in hours flown for the DoD and a lower average cost of aviation fuel that

---

we resell to customers. The decrease in fuel expense for the second quarter of 2023 compared to the second quarter of 2022 additionally reflects a greater decline in the average cost per gallon of aviation fuel that we resold to our customers compared to the second quarter of 2022.

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 decreased $0.5 million and $1.0 million during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022. The reduction reflects the net effect of operating fewer passenger hours and higher vendor fee rates.

Travel expense increased by $2.7 million and $8.1 million during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022. In addition to the increased number of crew members, travel expense increased during 2023 due to significantly higher airfares and hotel rates compared to the prior year.

Landing and ramp expense, which includes the cost of deicing chemicals, increased by $0.7 million and $0.2 million during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022, due to higher rates charged by airports.

Rent expense increased by $1.2 million and $2.7 million during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods of 2022 due to additional aircraft engines and facility locations under lease.

Non-Operating Income, Adjustments and Expenses

Interest expense increased by $7.2 million and $11.5 million during the three and six month periods ended June 30, 2023, respectively, compared to the corresponding periods 2022. Debt balances and interest rates under our Senior Credit Agreement increased year over year. We expect interest expense to increase in future periods due to increases in our revolver balances as we expand CAM's fleet and increased interest rates that float with prevailing SOFR under our Senior Credit Agreement.

We recorded unrealized pre-tax gains on financial instrument re-measurements of $1.8 million and $0.1 million during the three and six month periods ended June 30, 2023, respectively, compared to pre-tax gains of $6.0 million and $8.7 million for the corresponding periods in 2022. The gains and losses include the re-valuing, as of June 30, 2023 and 2022, the stock warrants and ATSG stock sale option granted to Amazon and interest rate swaps that we hold. Generally, the warrant values increase or decrease with corresponding increases or decreases in the ATSG common stock price during the measurement period. Additionally, the value of warrants depends partially on the probability that warrants will vest upon the execution of aircraft leases. Increases in the probability of a warrants vesting and the sales option exercise price being above the traded ATSG price results in higher liabilities and losses. Also, during the three month period ended June 30, 2022, ATSG 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.

Non-service components of retiree benefits resulted in net losses of $3.2 million and $6.4 million for the three and six month period ended June 30, 2023, respectively, compared to gains of $5.4 million and $10.8 million for the corresponding periods in 2022. The non-service component gain and losses of retiree benefits are determined by actuaries and include the amortization of unrecognized gain and loss 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, 2023 have been estimated utilizing a 24% rate based upon year-to-date income projected results for the full year. The effective rate can be impacted by a number of factors, including the continued impact of the apportionment of income among taxing jurisdictions, employee compensation limitations, the return of the meals and per diem deductibility limitations and our leasing efforts in our Ireland-based subsidiary.

The effective rate from continuing operations for the six month period ended June 30, 2023 was 24%. 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 other adjustments for adjusted pre-tax earnings from continuing operations (see items in the table above) was 23% and 23% for the three and six month periods ended June 30, 2023, respectively, compared to 22% and 23% for the corresponding periods in 2022.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Net cash generated from operating activities totaled $408.6 million and $250.2 million for the six month periods ended June 30, 2023 and 2022, respectively. The increase in operating cash flows for 2023 was driven by faster payments from customers and lower customer accounts receivable balances. Cash outlays for pension contributions were $1.2 million and $1.1 million for the six month periods ended June 30, 2023 and 2022, 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 $412.9 million and $294.2 million for the six month periods ended June 30, 2023 and 2022, respectively. Capital expenditures for the first half of 2023 included $303.2 million for the acquisition of eight Boeing 767-300 aircraft, two Airbus A321-200 aircraft and freighter modification costs; $103.9 million for required heavy maintenance; and $5.8 million for other equipment. 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.

Cash proceeds of $10.4 million and $0.2 million were received during the six month periods ended June 30, 2023 and 2022, respectively, primarily for the sale of aircraft engines.

During the six-month period ended June 30, 2023 we spent $0.8 million to invest in joint ventures compared to $16.5 million during the corresponding period in 2022. Our joint venture with Precision Aircraft Solutions, LLC, developed a passenger-to-freighter conversion program for Airbus A321-200 aircraft and our joint venture with GA Telesis Engine Services, LLC provides engine tear-down services to harvest and sell engine parts.

Net cash provided by financing activities was $10.7 million during the six month period ended June 30, 2023 and net cash provided by financing activities was $38.0 million during the corresponding period in 2022. During the first half of 2023, we made debt principal payments of $90.3 million and we drew $140.0 million from the revolving credit facility under the Senior Credit Agreement. During the corresponding period in the prior year, we made debt principal payments of $295.3 million and we drew $450.0 million from the revolving credit facility.

Commitments

As of June 30, 2023, we had 29 aircraft that were in or awaiting modification to a freighter configuration. Additionally, we placed non-refundable deposits and have agreements to purchase nine more Boeing 767-300 passenger aircraft and seven Airbus A330 aircraft through 2024. We expect to purchase additional aircraft for modification in 2023 and 2024. We outsource 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 2023 will be approximately $785 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 whether customer demand supports our return requirements as well as aircraft acquisitions, maintenance and modification processes.

Liquidity and Capital Resources

At June 30, 2023, we had $43.2 million of cash balances and $418.6 million available from the unused portion of the revolving credit facility under the Senior Credit Agreement as described in Note F of the accompanying consolidated financial statements. We expect our operations to continue to generate significant net cash in-flows after deducting required spending of approximately $240 million for heavy maintenance and other sustaining capital expenditures. To expand our fleet, we estimate that capital expenditures for aircraft purchases and freighter modifications will total $545 million for 2023. We believe that our current cash balance, forecasted cash flows

---

provided from customer leases and operating agreements, combined with the 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 the supplies chains and labor shortages may delay aircraft modification projects, pushing contractual obligations into later periods and could decrease the projected amount of capital expenditures.

CRITICAL ACCOUNTING ESTIMATES

The MD&A and certain other disclosures included elsewhere in this Form 10-Q 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 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 2022 Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risk for increasing 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 2022 Form 10-K

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of June 30, 2023, 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")) as of the end of the period covered by this Form 10-Q (the "Evaluation Date"). Based upon the evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, 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. In designing and evaluating the disclosure controls and procedures, the Company’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, the Company’s management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Control Over Financial Reporting

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, 2023 that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.

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. There have been no material changes to the Company's risk factors from the information disclosed in Item 1A of the Company's 2022 Form 10-K.

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 November 29, 2022, the Board of Directors of ATSG (the "Board") authorized the repurchase of up to $150.0 million of ATSG's outstanding common stock (the "2022 Repurchase Program"). The 2022 Repurchase Program does not require the repurchase of a specific number of shares or establish a time frame for any repurchase and the Board may terminate the 2022 Repurchase Program at any time. Repurchases may be made under the 2022 Repurchase Program from time to time in the open market or in privately negotiated transactions. There is no expiration date for the 2022 Repurchase Program. We repurchased $15.0 million in ATSG common stock under the 2022 Repurchase Program during the second quarter of 2023. As of June 30, 2023, the remaining available authorization under the 2022 Repurchase Program was $103.5 million.

The following table summarizes our repurchases of ATSG common stock under the 2022 Repurchase Program during the second quarter ended June 30, 2023:

Period						Total Number of Shares Purchased						Average Price paid Per Share						Total Number of Shares Purchased as Part of Publicly Announced Program						Maximum Dollar Value of Shares That May Yet Be Purchased Under the Program
