FORWARD LOOKINGCAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
StatementsThe 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 Quarterly Report on 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 historical facts are considered forward-lookinglimited to, statements (as that term is defined in the Private Securities litigation Reform Actregarding anticipated operating results, prospects and levels of 1995). Words such as “future,assets under management, technological developments, economic trends, expected transactions and similar matters. The words “may,“anticipates,“believe,“believes,“expect,“estimates,“anticipate,“expects,“target,“intends,“goal,“plans,“project,“predicts,“estimate,” “guidance,” “forecast,” “outlook,” “will,” “would,“continue,“could,“likely,“can,“should,“may,“hope, “seek,” “plan,” “intend” and variations of such words and similar terms and expressions are intended to identify forward-looking statements. TheseSimilarly, 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 expectations,information, plans and estimates and projections as of the date of


this filing, and involveForm 10-Q. New risks and uncertainties arise from time to time, and factors that are inherently difficultthe Company currently deems immaterial may become material, and it is impossible for the Company to predict. Actual resultspredict these events or how they may differ materially from those expressed inaffect it. Except as may be required by applicable law, the Company undertakes no obligation to update any forward-looking statements forto reflect changes in underlying assumptions or factors, new information, future events or other changes. The Company does not endorse any number of reasons, including those describedprojections regarding future performance that may be made by third parties.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

Nature of Operations
Air Transport Services Group, Inc. ("ATSG" and, together with its subsidiaries, the "Company," "we," "us," and "our")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.
ATSG'sThe Company's leasing subsidiary, Cargo Aircraft Management, Inc. (“CAM”), leases aircraft to each of ATSG's airline subsidiariesthe Company's airlines as well as to non-affiliated airlines and other lessees. ATSG's airline subsidiaries,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 networksnetwork 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 20212022 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 nonconsolidatednon-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.

Uncertainties
The Company has experienced disruptions to its operations, such as shortages of personnel, parts shortages, maintenance delays, shortages of transportation and hotel accommodations for flight crews, facility closures and other supply chain related issues as a result of the COVID-19 pandemic. The emergence of COVID-19 variants could result in reduced revenues, additional costs and supply chain delays for the Company. The extent of the impact that the coronavirus pandemic will have on our future operations and financial results will depend on future developments, including: the duration, spread, severity and recurrence of the COVID-19 variants; vaccination rates, the effectiveness of vaccines, the duration and scope of government orders and local restrictions as well as the extent of the impact of the pandemic on overall economic conditions.
In February 2022, war started in Ukraine, intensifying geopolitical pressures worldwide. While the Company's operations have not been detrimentally impacted directly, additional supply chain disruptions and inflationary pressures could have an impact on overall economic conditions, as well as the Company's operations and financial results.
Accounting Standards Updates
In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU"(“ASU”) No. 2020-06, "Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"). This new standard removes the separation models for convertible debt with cash conversion or beneficial conversion features. It eliminates the "treasury stock" method for convertible instruments and requires application of the “if-converted” method for certain agreements. The Company adopted ASU 2020-06 on January 1, 2022 using the modified retrospective approach which resulted in the following adjustments:
(in thousands)December 31, 2021Adoption of ASU 2020-06January 1, 2022
Balance Sheet line item:
Principal value$(258,750)$— $(258,750)
Unamortized issuance cost$2,889 $— $2,889 
Unamortized discount$24,215 $(24,215)$—

Retained earnings$(309,430)$(20,871)$(330,301)

After adopting ASU 2020-06, the Company's Convertible Notes due 2024 (as defined and discussed in Note F) are reflected entirely as a liability as the embedded conversion feature is no longer separately presented within stockholders' equity, which also eliminated the non-cash discount. Accordingly, earnings no longer reflect the discount amortization expense which was $6.4 million of interest expense, net of income taxes during 2021. After giving effect for the adoption, the effective interest rate on the Convertible Notes is 1.5%.
ASU 2020-06 requires the application of the more dilutive if-converted method when calculating the impact of the Convertible Notes on earnings per diluted share. The adoption of ASU 2020-06 does not change the accounting treatment of shares to be delivered by the convertible note hedges (see Note F) purchased by the Company that are designed to offset the shares issued to settle its Convertible Notes, which are anti-dilutive and not reflected in earnings per diluted share.

The Company has a 49% ownership in a joint-venture agreement with Precision Aircraft Solutions, LLC, to develop a passenger-to-freighter conversion program for Airbus A321-200 aircraft. In April of 2022, the Company acquired a 40% ownership interest in the joint-venture company GA Telesis Engine Services, LLC to provide engine tear-down services to harvest and sell engine parts. The Company accounts for its investment in these joint ventures under the equity method of accounting, in which the carrying value of each investment is reduced for the Company's share of the non-consolidated affiliates' operating results.
The carrying value of the joint ventures totaled $21.6$21.0 million and $10.3$18.9 million at June 30, 20222023 and December 31, 2021,2022, 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.

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.

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

Additionally, Amazon can earn incrementaladditional warrants rights offor up to 2.9 million common shares under the 2018 Investment Agreement by leasing up to five more cargo aircraft from the Company before January 2026. Incremental warrants granted to Amazon for ASI’s commitment to any such future aircraft leases will have an exercise price based on the volume-weighted average price of the Company's shares during the 30 trading days immediately preceding the contractual commitment for each lease.
For all outstanding warrants vested, Amazon may select a cashless conversion option. Assuming ATSG's stock price at the time of conversion is above the warrant exercise price, Amazon would receive fewer shares in exchange for any warrants exercised under the cashless option by surrendering the number of shares with a market value equal to the exercise price.
The Company 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 hasand 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.
In accordance with the 2016 Investment Agreement, on September 8, 2020, the final number of shares issuable under the third tranche of warrants was determined to be 0.5 million common shares. As a result, under GAAP, the value of the entire warrant grant under the 2016 Investment Agreement was remeasured on September 8, 2020, and its fair value of $221 million was reclassified from balance sheet liabilities to paid-in-capital. In October 2020, upon the execution of the 10th and final aircraft lease of the December 2018 commitment, warrants for 14.8 million shares were remeasured on October 1, 2020, and their fair value of $154 million was reclassified from balance sheet liabilities to paid-in-capital. In December 2021, upon execution of the 12th and final aircraft lease of the May 2020 commitment, warrants for 7.0 million shares were remeasured on December 7, 2021, and their fair value of $82.4 million was reclassified from balance sheet liabilities to paid-in-capital.
As of June 30, 20222023 and December 31, 2021,2022, the Company's liabilities reflected warrants and Amazon sale options from the 2018 Amazon agreements having a fair value of $0.9$1.8 million and $0.9$0.7 million, respectively. During the three month and six monthsmonth periods ended June 30, , 20222023, the re-measurements of warrants and sale options to fair value resulted in a gainnet non-operating losses of $0.1$0.3 million and $0.1$1.1 million before the effect of income taxes, respectively, compared to net non-operating gains of $33.5$0.1 million and $40.4$0.1 million before the effect of income taxes, respectively, forin the corresponding periods of 2021.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 the Company’sATSG's common stock price, the volatility of the Company’sATSG's common stock, the expected dividend yield, exercise price and the risk-free interest rate (Level 2 inputs). The fair value of the stock warrant obligations for unvested stock warrants, conditionally promised granted


to Amazon for the execution of incremental, future aircraft leases, include additional
14


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

In September 2017, ATSG issued $258.8 million aggregate principal amount of 1.125% convertible senior notesConvertible 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.

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 at thefor a cash repurchase price equal to the principal amount of the notes, plus any accrued and unpaid interest. The Company
ATSG has the right to settle the Convertible Notes in cash, the Company’sATSG common shares or a combination of cash and the Company’sATSG common shares, at the Company’s election.shares. The initial conversion rate is 31.3531.3475 common shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $31.90 per common share). If a “make-whole fundamental change” (as defined in the offering circular with the Convertible Notes) occurs, the CompanyATSG 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
17


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.

NOTE H—COMMITMENTS AND CONTINGENCIES
Payroll Support Programs
During 2020, two of the Company's airline subsidiaries, OAI and ATI, received government funds totaling $75.8 million pursuant to payroll support program agreements under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). In February 2021, OAI was approved for $37.4 million of additional non-repayable government funds pursuant to a payroll support program agreement under the Consolidated Appropriations Act, 2021 (the “PSP Extension Law”). This grant was subsequently increased by $5.6 million. Further, in April 2021, OAI was approved for $40.0 million of additional non-repayable government funds pursuant to a payroll support program agreement under the American Rescue Plan Act of 2021 (the "American Rescue Plan").
18


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

Lease Commitments
The Company leasesleases property, aircraft, aircraft engines and other types of equipment under operating leases. The Company's airlines operate sevenfifteen 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 sixnine years. The Company is obligated to pay the lessor for maintenance, real estate taxes, insurance and other operating expenses on certain property leases. These expenses are variable and are not included in the measurement of the lease asset or lease liability. These expenses are recognized as variable lease expense when incurred and are not material. Equipment leases include ground support and industrial equipment as well as computer hardware with fixed rent payments and terms of one month to five years.
The Company records the initial right-to-use asset and lease liability at the present value of lease payments scheduled during the lease term. For the six month period endingmonths ended June 30, 20222023 and 2021,2022, non-cash transactions to recognize right-to-use assets and corresponding liabilities for new leases were $12.7$1.0 million and $5.9$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 2.3% compared to 2.4% at December 31, 2021.3.5% 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. TheOur weighted-average remaining lease term is 3.54.1 years and 3.84.3 years as of June 30, 20222023 and December 31, 2021,2022, respectively.

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.

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 otherits ABX employees thatthat meet minimum eligibility requirements. ABX also sponsors non-qualified defined benefit pension plans for certain employees. These non-qualified plans are unfunded. Employees are no longer accruing benefits under any of the defined benefit pension plans. ABX also sponsors a post-retirement healthcare plan for its ABX crewmembers, which is unfunded. Benefits for covered individuals terminate upon reaching age 65 under the post-retirement healthcare plans.
The accounting and valuation for these post-retirement obligations are determined by prescribed accounting and actuarial methods that consider a number of assumptions and estimates. The selection of appropriate assumptions and estimates is significant due to the long time period over which benefits will be accrued and paid. The long term nature of these benefit payouts increases the sensitivity of certain estimates of our post-retirement obligations. The assumptions considered most sensitive in actuarially valuing ABX’s pension obligations and determining related expense amounts are discount rates and expected long term investment returns on plan assets. Additionally, other assumptions concerning retirement ages, mortality and employee turnover also affect the valuations. Actual results and future changes in these assumptions could result in future costs significantly higher than those recorded in our results of operations.
ABX measures plan assets and benefit obligations as of December 31 of each year. Information regarding ABX’s sponsoredABX-sponsored defined benefit pension plans and post-retirement healthcare plans followfollows below. The accumulated benefit obligation reflects pension benefit obligations based on the actual earnings and service to-date of current employees.

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, 20222023 have been estimated utilizing a rate of 23%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 first six months of 2022ended June 30, 2023 was 23%23.8%. The final effective tax rate for the year 20222023 will depend on the actual amount of pre-tax book results by the Company for the full year, the additional conversions of employee stock awards, foreign earnings,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 taxtax assets, including its loss carryforwards, management does not expect to pay federalcash payments for income taxes until 2025 or later.will be limited through 2025. The Company may, prior to such time, beis required to pay some federal tax due to loss carryforward usage limitations and certain state and local income taxes.

Basic weighted average shares outstanding for purposes of basic earnings per share are less than the shares outstanding due to 375,139482,010 shares and 482,300375,139 shares of restricted stock for 20222023 and 2021,2022, 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.

ITEM 2. MANAGEMENT’SMANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") has been prepared with reference to the historical financial condition and results of operations of Air Transport Services Group, Inc.,ATSG and its subsidiaries. Air Transport Services Group, Inc. and its subsidiaries may hereinafter individually and collectively be referred to as "the Company", "we", "our", or "us" from time to time. The MD&A describes the principal factors affecting our results of operations, financial condition, cash flow, liquidity and capital resources. The MD&A should be read in conjunction with the accompanying unaudited condensed consolidated financial statements and related notes prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") contained in this reportForm 10-Q and the audited consolidated financial statements and related notes prepared in accordance with GAAP contained in our 20212022 Form 10-K.

BACKGROUND
We lease aircraft and provide airline operations, aircraft modification and maintenance services, ground services, and other support services to the air transportation and logistics industries. Through ATSG's subsidiaries, we offer a range of complementary services to delivery companies, freight forwarders, e-commerce operators, airlines and government customers. Our principal subsidiaries include our aircraft leasing company (CAM) and three independently certificated airlines (ABX, ATI and OAI).
We have two reportable operating segments:
CAM offers aircraft leasing and related services to external customers and also leases aircraft internally to the Company'sour 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.
OurWe also provide other business operations, which primarily provide support services to our ACMI Services customers and other airlines by leveraging our knowledge and capabilities developed for our own operations over the transportation industry, include providingyears. 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 customers, cargo load transferUnited States Postal Service (USPS) facilities and sortingsimilar services as well as relatedto certain ASI hub and gateway locations in the United States. We provide maintenance for ground equipment, maintenancefacilities and material handling equipment and we resell aviation fuel in Wilmington, Ohio. Additionally, we provide flight training services. TheseThe operations described in this paragraph do not constitute a separate reportable segments.segment and are reported in “All other.”
At June 30, 2022,2023, we owned 110106 Boeing aircraft that were in revenue service. We also owned fourteentwenty Boeing 767-300 aircraft and fivenine Airbus 321-200 aircraft either already undergoing or awaiting induction into the freighter conversion process at June 30, 2022.2023. In addition to these aircraft, we leased four passenger aircraft from third parties and operated sevenfifteen freighter aircraft provided by customers for whom we provide services under CMI agreements.
Due to the strong demand for medium widebody and narrow body freighters and as part of our continued growth strategy to expand and diversify our fleet, during 2021 we secured additional aircraft conversion slots over the next few years. We continue to work closely with Israel Aerospace Industries and have forged new conversion relationships with Boeing and Elbe Flugzeugwerke (“EFW”). Further, we perform our own conversions of the Airbus A321 aircraft through a joint venture arrangement.
Customers
Our largest customers are ASI, which is a subsidiary of Amazon, the DoD and DHL.
Revenues from our commercial arrangements with ASI comprised approximately 34% and 36%34% of our consolidated revenues during the six month periods ended June 30, 20222023 and 2021,2022, respectively. As of June 30, 2022,2023, we leased 4238 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 fivenine other Boeing 767 aircraft provided by ASI. We also provide ground services and aircraft maintenance services to ASI.

Ten of the fifteen


12 Boeing 767 aircraft were being operated by the Company'sour airlines for DHL. Additionally, we operated twosix Boeing 767 aircraft that were provided by DHL. In February 2022, the Company and DHL agreed to a six-year extension of its dry leases for five Boeing 767 freighters as well as an extension of the CMI agreement with DHL for ABX to operate aircraft through April 2028. The CMI agreement was subsequently expanded to include two additional 767 freighters.
The DoD comprised 29%30% and 24%29% of our consolidated revenues during the six month periods ended June 30, 20222023 and 20212022 respectively, derived primarily from operating passenger and combi charter flights. We utilize our fleet of fifteenfourteen 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 yearone-year agreements.

After removing the effects of these items, adjusted pre-tax earnings from continuing operations, a non-GAAP measure (a definition and reconciliation of adjusted pre-tax earnings from continuing operations follows), were $66.9 million and $131.1$0.1 million for the three and six month periods ended June 30, 2022,2023, 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 $37.1$66.9 million and $57.2$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 2021. Improved results were driven by additional aircraft leases to external customers, an increaseleases. The decrease in the numbersix month period ended June 30, 2023 of freighter$35.4 million is primarily due to a lower level of passenger operations within ACMI Services in the first quarter and fewer aircraft we operate and more passenger block hours for the DoD compared to the previous year's quarter.under lease with customers.

AdjustedWe define adjusted pre-tax earnings from continuing operations, a non-GAAP financial measure, isas 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 fromfor the fair value re-measurement of financial instrument valuationsinstruments including warrants issued to Amazon; (iii) customer lease incentive amortization; (iv) gains and (iv)losses from non-consolidated joint ventures; and (v) charges related to the start-up costs and expensesdischarge of a non-consolidated joint venture.fire suppression system in the Company's aircraft hangar, net of related insurance recoveries. We exclude these items when calculating adjustedfrom pre-tax earnings from continuing operations because they are distinctly different in their predictability or not closely related to our on-going operating activities. We also excluded the recognition of government grants from adjusted earnings to improve comparability between periods. Management uses adjusted pre-tax earnings from continuing operations to compare the performance of core operating results between periods. Presenting this non-GAAP financial measure provides management and investors with a comparative metric of fundamental operations while highlighting changes to certain items among periods. Adjusted pre-tax earnings from continuing operationsresults should not be considered in isolation or as a substitute for analysis of the Company's results as calculated and reported under GAAP.
The Company's earnings were impacted by the fair value re-measurement of the Amazon warrants classified in liabilities at the end of each reporting period, customer incentive amortization and the related income tax effects. The fair value of the warrants issued or issuable to Amazon were recorded as a customer incentive asset and are amortized against revenues over the duration of the aircraft leases. Our accounting for the warrants issued to Amazon has been determined in accordance with the financial reporting guidance for financial instruments. For additional information about the warrants issued to Amazon, see the accompanying notes to the financial statements included in this report.

CAM Segment


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 added ten Boeing 767-300 freighter aircraft to its portfolio since July 1, 2021. CAM grew its
CAM's revenues by $21.1 million and $44.7 million during the first three and six months of 2022, respectively, compared to the same periods in 2021.
As of June 30, 2022 and 2021, CAM had 89 and 80 aircraft under lease to external customers, respectively. Revenues from external customers totaled $80.8$84.2 million and $157.5 million for the three and six months periods ended June 30, 2022, respectively, compared to $66.7 million and $127.5 million for the corresponding periods of 2021. Since July 1, 2021, CAM placed eleven more Boeing 767-300 aircraft with external customers under long-term leases. Additionally, in October of 2021, CAM began to offer engine power coverage to lessees of CAM's General Electric powered Boeing 767-200 aircraft. Under this service, CAM is responsible for providing and maintaining engines for its lease customers as needed through a pool of engines. Revenues from external customers increased $4.6 million and $10.9 million for the three and six months ended June 30, 2022 compared to the corresponding periods in 2021 for this engine service. CAM's revenues from the Company's airlines totaled $28.9 million and $59.1$167.4 million for the three and six month periods ended June 30, 2022,2023, respectively, compared to $21.9$80.8 million and $44.4$157.5 million for the correspondingsame periods in 2021.

and $44.0 million for the corresponding periods in 2021. Increased pre-tax earnings reflect2022, as a result of new aircraft leases in 2023 and 2022, offset by the tenreturn 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 into servicethese five aircraft with external customers under long-term leases. Additionally, since July 1, 20212022, ten 767-200 freighters were returned from lease. CAM is currently prepping two of these 767-200 freighters for re-lease, and decreases in internally allocated interest expense of $3.4has 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 $5.0$2.9 million for the three and six month periods ended June 30, 2022,2023, respectively, compared to the corresponding periods of 20212022, due to lower company-widethe reduction in leased 767-200 aircraft.
CAM's pre-tax earnings, inclusive of internally allocated interest expense, and debt. Increased pre-tax earnings were also offset by increased depreciation of $6.4$31.0 million and $15.7$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, 2022,2023, respectively, comparedprimarily due to the corresponding periodsnew 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 2021 driven by the addition of aircraft.
In addition to the 14June 30, 2023, CAM's fleet included 20 Boeing 767-300 aircraft and fivenine Airbus A321-200 aircraft which were in or awaiting the modification process at June 30, 2022,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 elevennine more Boeing 767-300 aircraft four moreand seven Airbus A321-200A330-300 aircraft during 2023 and 2024. Eight of these aircraft are scheduled to be leased with external customers in 2024, six Airbus A330in 2025 and two in 2026. If future market conditions affect the demand for modified aircraft through 2024. or the projected returns on our fleet expansion, we have the flexibility to reduce planned growth investments in 2024 and beyond.
CAM's future operating results will depend on its continuing ability to convert passenger aircraft into freighters within planned costs and within the timeframestime frames required by customers. During the second half of 2022, we expect to lease to external customers at least four more newly modified Boeing 767-300 freighters, two newly modified Airbus A321-200 freighters and re-deploy one Boeing 767-200 freighter. CAM's future operating results will also depend on the timing and lease rates under which aircraft are redeployed when leases expire. Additionally, CAM'sredeployed. 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 operating results from engine power services will depend upon engine cycles operated, the number of engine overhauls and the severity of unscheduled maintenance events.years.
ACMI Services
Total revenues from ACMI Services increased $74.2$18.7 million and $157.2$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, 2022,2023, respectively, compared with the corresponding periods of 2021. Increased revenues for 2022 reflected a 21% and 30% increase in block hours flown for DoD troop movements particularly to Europe for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods in 2021, as well as eight additional freighter aircraft added to operations compared to the second quarter of 2021, including four more customer-provided aircraft that are not owned by CAM. Revenues also increased due to fuel expenses that are billed through to the DoD and charter customers. The customer fuel portion of ACMI Services revenue increased approximately $23 million and $42 million during the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods in 2021. Overall, customer block hours increased 9% and 15% for the three and six month periods ended June 30, 2022, respectively, compared to the corresponding periods in 2021, with increases in block hours flown for the DoD, DHL and Amazon. As of June 30, 2022 and 2021, ACMI Services included 84 and 76 in-service aircraft, respectively.
ACMI Services had pre-tax earnings of $21.8 million and $44.0 million for the three and six month periods ended June 30, 2022, respectively, compared to $44.8 million and $66.0 million for the corresponding periods in 2021,of 2022 inclusive of internally allocated interest expense and the recognition of pandemic-related government grants of $38.3 million and $66.3 million, respectively. Pre-tax earnings, excluding the recognition of government grants, for the three and six month periods ended June 30, 2022 improved $15.3 million and $44.3 million, respectively, compared to the corresponding periods of 2021. Improved earnings were a result of the increased number of aircraft in operations and more block hours flown during the first half of 2022 compared to 2021. While employee salaries and wages, contract labor, fuel and travel expenses all increased relative to the prior year period, thisexpense. ACMI Services was offsetimpacted by additional operating volumes which drove earnings higher. Internallyinternally allocated interest expense decreased $1.8 million to $2.6of $2.4 million and decreased $3.0 million to $6.0$4.0 million for the three and six month periodsperiod ended June 30, 2022,2023, 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 2021.2023. 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.

The number of total employees has increases by 3% compared to the previous year. In addition, salaries and wages2022. 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 $5.7$1.3 million and $16.8$4.0 million during the three and six month periods ended June 30, 2022,2023, respectively, compared to the corresponding periods of 2021.2022. The increase reflects incremental depreciation for ten additionalfive newly converted aircraft as well as additional depreciation expenseadded to its operating fleet since July 1, 2022. Since July 1, 2022, airframes for engines that are now being serviced and maintained by CAM under engine power coverage arrangements.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 decreasedincreased by $6.5$11.0 million or 28% and $12.8$19.2 million or 25% during the three and six month periods ended June 30, 2022,2023, respectively, compared to the corresponding periods of 2021.

Interest expense decreased by $5.6$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 threecorresponding periods in 2022. The gains and six months endedlosses include the re-valuing, as of June 30, 2023 and 2022, comparedthe 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 periods for 2021. Interest expense decreased due to lower interest rates on our borrowings underincreases or decreases in the Senior Credit Agreement and lower average debt balances outstandingATSG 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, dDuringuring the three month period ended June 30, 2022, the companyATSG repurchased $120.0 million of its Senior Notes par value in the open market resulting in a net pre-tax gain of $4.5 million, net of fees which was recorded under net gain on financial instruments on the income statement during the corresponding period.

The pre-tax gains for 2022 are primarily a result of the impact of higher market interest rates on the interest rate derivatives that we held. (See Note G for additional information about the interest rate derivatives.). The pre-tax gains for 2021 are primarily a result of re-valuing the stock warrants granted to Amazon. The warrant values generally increase or decrease with corresponding increases or decreases in the ATSG share price during the measurement period. Additionally, the value of certain warrants depends partially on the probability that such warrants will vest upon the execution of aircraft leases. Increases in the probability of warrants vesting results in higher liabilities and losses. In December 2021, most of the outstanding warrants were reclassified from liabilities to paid in capital and are no longer subject to periodic reevaluation. (See Note C for additional information about the Amazon warrants.)
Non service components of retiree benefits resulted in net gains of $5.4 million and $10.8 million for the three and six month periods ended June 30, 2022 compared to net gains of $4.5 million and $8.9 million for the corresponding periods of 2021.in 2022.

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, 20222023 have been estimated utilizing a 23%24% rate based upon year-to-date income projected results for the full year.

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

Discontinued Operations
The financial results of discontinued operations primarily reflect workers' compensation cost adjustments and other benefits for former employees previously associated with ABX's former hub operations pursuant to which ABX performed package sorting services for DHL. Gains related to the former sorting operations were $0.9 million for the first half of 2022,2023, respectively, compared to less than $0.1 million22% and 23% for the corresponding period of 2021.

Commitments
As of June 30, 2022, the Company2023, we had 1929 aircraft that were in or awaiting modification to a freighter configuration. Additionally, we placed non-refundable deposits and have agreements to purchase elevennine more Boeing 767-300 passenger aircraft four more Airbus 321-200 and sixseven Airbus A330 aircraft through 2024. We expect to purchase additional aircraft for modification in 2023. The Company outsources2023 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 20222023 will be approximately $625$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.

We expect our operations to continue to generate significant net cash in-flows after deducting required spending of approximately $205$240 million for heavy maintenance and other sustaining capital expenditures during the year 2022.expenditures. To expand our fleet, we estimate that capital expenditures for aircraft purchases and freighter modifications will total $420$545 million for 2022.2023. We believe that the Company'sour current cash balance, forecasted cash flows


provided from its customer leases and operating agreements, combined with borrowing availability under itsthe 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 supplythe supplies chains and labor shortages may delay aircraft modification projects, pushing contractual obligations into later periods and could have an impact ondecrease the projected amount of capital expenditures.

CRITICAL ACCOUNTING ESTIMATES
The MD&A and certain other disclosures included elsewhere in this reportForm 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 "SUMMARY OF FINANCIAL STATEMENT PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES" in the accompanying notes to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this Form 10-Q. Except as provided in Note A, our critical accounting policies and estimates have not changed materially from those disclosed in our 20212022 Form 10-K.

The Company is exposed to market riskrisk for changes inincreasing 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 20212022 Form 10-K.10-K



ITEM 4. CONTROLS AND PROCEDURES
(a) Evaluation of Disclosure Controls and Procedures
As of June 30, 2022,2023, 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.
(b) Changes in Internal ControlsControl 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, 20222023 that hashave 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. Many of these risks areThere have been no material changes to the Company's risk factors from the information disclosed in Item 1A of the Company's 20212022 Form 10-K.
In addition to the risks previously disclosed, the recent outbreak of war in Ukraine and the emergence of COVID-19 variants in China and other countries may result in further supply chain disruptions. These matters, coupled with inflationary pressures, could have an impact on overall economic conditions as well as the Company's operations and financial results.
As disclosed in Note H of this report, on August 7, 2022 the fire suppression system discharged at one of our aircraft maintenance hangars in Wilmington, Ohio, impacting employees, three aircraft, and equipment in and around the hangar. We expect that employee claims, property and equipment damage, customer claims and certain costs of business interruption will be covered by insurance, subject to customary deductibles and policy limits. However, our operating results may be impacted by losses and liabilities that are not covered by our insurance. Additionally, property losses will be recognized as they become known to us and related expenses as they are incurred, however insurance proceeds may not be recognized until later periods. As a result, the impact on our earnings may vary from period to period. The timeframes needed to return the hangar and aircraft to operating condition are not determinable at this time. If some or all of these assets remain inoperable for an extended period of time, our operating results could be negatively impacted.
Other risks that are currently unknown to management or are currently considered immaterial or unlikely, could also adversely affect the Company.
