The Boeing Company and Subsidiaries
Notes to the Condensed Consolidated Financial Statements
(Dollars in millions, except per share amounts or as otherwise stated)
(Unaudited)
Note 1 – Basis of Presentation
The condensed consolidated interim financial statements included in this report have been prepared by management of The Boeing Company (herein referred to as “Boeing”, the “Company”, “we”, “us”, or “our”). In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation are reflected in the interim financial statements. The results of operations for the period ended September 30, 2024, are not necessarily indicative of the operating results for the full year. The interim financial statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, included in our 2023 Annual Report on Form 10-K. We added a new financial statement line item to the Condensed Consolidated Statements of Cash Flows for cash invested in Supplier notes receivable and reclassified the corresponding amounts in the prior period financial statements to conform to the current period presentation.
Liquidity Matters
During the nine months ended September 30, 2024, net cash used by operating activities was $8.6 billion. The cash outflow was primarily driven by our commercial airplane business. Commercial airplane cash outflows reflect slowed production and deliveries as a result of ongoing safety and quality improvement actions the Company is taking following the Alaska Airlines accident on January 5, 2024, as well as supply chain constraints. Additionally, the ongoing work stoppage initiated on September 13, 2024, by the International Association of Machinists and Aerospace Workers District 751 (IAM 751) has paused production of certain commercial aircraft models (737, 767, 777 and 777X aircraft) as well as production of commercial derivative aircraft for our Defense, Space & Security business (KC-46A Tanker and P-8A Poseidon). The IAM 751 work stoppage is also significantly reducing aircraft deliveries and adversely impacting our financial position, results of operations and cash flows.
At September 30, 2024, cash and short-term investments totaled $10.5 billion. Our total debt balance was $57.7 billion at September 30, 2024, up from $52.3 billion at December 31, 2023. On May 1, 2024, we issued $10 billion of fixed-rate senior notes. At September 30, 2024, we had $10.0 billion of unused borrowing capacity on revolving credit line agreements. On May 15, 2024, we entered into a $4.0 billion five-year revolving credit agreement expiring in May 2029. Our $3.0 billion three-year revolving credit agreement expiring in August 2025 and $3.0 billion five-year revolving credit agreement expiring in August 2028 each remain in effect. We anticipate these credit lines will primarily serve as back-up liquidity to support our general borrowing needs. On October 14, 2024, we entered into a $10.0 billion 364-day supplemental credit agreement (see Note 12 for additional information). We continue to be in full compliance with all covenants contained in our debt and credit facility agreements.
We continue to maintain investment grade credit ratings. Moody’s downgraded our short term and long term credit ratings to Baa3/P-3 in April 2024. Moody's and S&P placed our ratings on review for downgrade in September 2024 and October 2024, respectively. A number of factors could cause us to incur increased borrowing costs and/or to have greater difficulty accessing public and private markets, including further credit rating downgrades. At September 30, 2024, trade payables included $2.7 billion payable to suppliers who have elected to participate in supply chain financing programs compared with $2.9 billion at December 31, 2023. In future quarters, our suppliers' access to supply chain financing could be curtailed or more expensive if our credit ratings are further downgraded.
We are implementing actions to improve liquidity. We instituted temporary furloughs and hiring freezes across the Company for all levels and paused pay increases for executive and management promotions. We are reducing discretionary spending as well as reducing or deferring non-essential capital expenditures. We are also pausing the issuance of the majority of supplier purchase orders on the 737, 767, 777, and 777X programs due to IAM 751's ongoing work stoppage. In addition, on October 11, 2024, we announced that we plan to reduce the size of our total workforce by roughly 10 percent.
9

Our planned acquisition of Spirit AeroSystems Holdings, Inc. (Spirit) will be an all-stock transaction pursuant to the Agreement and Plan of Merger entered into on June 30, 2024 (see Note 2 for additional information).
Notwithstanding the actions described above to improve liquidity, we expect negative operating cash flows in future quarters until IAM 751 employees return to work, production resumes and deliveries ramp up.
Based on our current best estimates of market demand, planned production rates, timing of cash receipts and expenditures, and our expected ability to successfully implement actions to improve liquidity, we believe it is probable that we will be able to fund our operations for the foreseeable future. We also believe we have the ability to access additional liquidity.
Use of Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Goodwill
We performed our annual goodwill impairment test as of April 1, 2024, using a qualitative assessment. We determined the fair value of each of our reporting units substantially exceeded their respective carrying values. Our Military Aircraft reporting unit within our Defense, Space & Security (BDS) segment had goodwill of $1,295 and a negative carrying value at September 30, 2024.
Long-term Contracts
Substantially all contracts at our BDS segment and certain contracts at our Global Services (BGS) segment are long-term contracts with the U.S. government and other customers that generally extend over several years. Changes in estimated revenues, cost of sales, and the related effect on operating income are recognized using a cumulative catch-up adjustment which recognizes, in the current period, the cumulative effect of the changes on current and prior periods based on a long-term contract’s percentage-of-completion. When the current estimates of total revenues and costs at completion for a long-term contract indicate a loss, a provision for the entire reach-forward loss on the long-term contract is recognized.
The table below reflects the impact of net cumulative catch-up adjustments for changes in estimated revenues and costs at completion across all long-term contracts, including the impact to Loss from operations from changes in estimated losses on unexercised options.

Note 2 – Spirit Acquisition
On June 30, 2024, we entered into an Agreement and Plan of Merger (the Merger Agreement) pursuant to which we have agreed to acquire Spirit in an all-stock transaction at an equity value of approximately $4,700, or $37.25 per share of Spirit Class A Common Stock. The transaction will include the assumption of Spirit's net debt at closing.
10

Each share of Spirit common stock will be exchanged for a number of shares of Boeing common stock equal to an exchange ratio between 0.18 and 0.25, calculated as $37.25 divided by the volume weighted average share price of Boeing shares over the 15-trading-day period ending on the second trading day prior to the closing (subject to a floor of $149.00 per share and a ceiling of $206.94 per share). Spirit stockholders will receive 0.25 Boeing shares for each of their Spirit shares if the volume-weighted average price is at or below $149.00, and 0.18 Boeing shares for each of their Spirit shares if the volume-weighted average price is at or above $206.94 per share.
Boeing's acquisition of Spirit will include substantially all Boeing-related commercial operations, as well as certain other operations.
Spirit has also entered into a binding term sheet with Airbus SE (Airbus) setting forth the terms upon which Airbus will, assuming the parties enter into definitive agreements and receive all required regulatory approvals, acquire certain commercial work packages that Spirit performs for Airbus concurrently with the closing of the Boeing-Spirit merger. In addition, Spirit is proposing to sell certain of its operations, including those in Belfast, Northern Ireland (non-Airbus operations); Prestwick, Scotland; Subang, Malaysia; Biddeford, Maine; and Woonsocket, Rhode Island.
The transaction is expected to close mid-2025 and is subject to the sale of the Spirit operations related to certain Airbus commercial work packages and the satisfaction of customary closing conditions, including regulatory and Spirit stockholder approvals.
The Merger Agreement contains certain termination rights, including that either Boeing or Spirit may terminate the Merger Agreement if, subject to certain limitations, the transaction has not been consummated by March 31, 2025 (subject to three automatic three-month extensions if on each such date all of the closing conditions except those relating to regulatory approvals have been satisfied or waived) (the Outside Date). Additionally, Spirit may terminate the Merger Agreement under specified circumstances to accept an unsolicited Superior Proposal (as defined in the Merger Agreement) from a third party, and we may terminate the Merger Agreement if, before Spirit stockholder approval has been obtained, the Spirit Board of Directors changes its recommendation that Spirit’s stockholders adopt the Merger Agreement. In addition, if either party breaches or fails to perform any of its representations, warranties or covenants under the Merger Agreement such that the related conditions to the other party's obligation to consummate the Merger would not be satisfied, and such breach or failure is not curable by the Outside Date or, if curable by the Outside Date, has not been cured within 30 days following notice thereof, such other party may terminate the Merger Agreement.
The Merger Agreement provides that Spirit will be required to pay Boeing a termination fee of $150 if the Merger Agreement is terminated under specified circumstances in which the Spirit Board of Directors changes its recommendation that Spirit’s stockholders adopt the Merger Agreement, Spirit terminates the Merger Agreement in order to accept a Superior Proposal as set forth in the Merger Agreement, or Spirit consummates a Qualifying Transaction (as defined in the Merger Agreement) following the termination of the Merger Agreement.
The Merger Agreement also provides that we will be required to pay Spirit a termination fee of $300 if the Merger Agreement is terminated by Spirit or Boeing under certain specified circumstances as a result of the parties' failure to obtain the required regulatory approvals by the Outside Date or in the event that any law or order related to the required regulatory approvals or any applicable antitrust law or foreign investment law prohibits the consummation of the Merger.
Note 3 – Earnings Per Share
Basic and diluted earnings per share are computed using the two-class method, which is an earnings allocation method that determines earnings per share for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings.
11

Basic earnings per share is calculated by taking net earnings attributable to Boeing Shareholders, less earnings available to participating securities, divided by the basic weighted average common shares outstanding.
Diluted earnings per share is calculated by taking net earnings attributable to Boeing Shareholders, less earnings available to participating securities, divided by the diluted weighted average common shares outstanding. Diluted weighted average common shares outstanding is calculated using the treasury stock method.
The elements used in the computation of Basic and Diluted loss per share were as follows:

Note 4 – Income Taxes
We computed our 2024 interim tax provision using an estimated annual effective tax rate of (1.9)%, adjusted for discrete items. Our 2024 estimated annual effective tax rate is primarily driven by taxes on non-U.S. operations. The forecasted 2024 tax provision as estimated at September 30, 2024, remained relatively consistent with that estimated in the second quarter of 2024, despite increased forecasted pre-
12

tax losses. This resulted in a corresponding change in the annualized effective tax rate during the three months ended September 30, 2024. The effective tax rate for the three months ended September 30, 2024, was 0.8% and reflects additional tax benefits to adjust prior quarters' results to the annual effective tax rate. The effective tax rates were 1.8% and (10.8)% for the nine months ended September 30, 2024 and 2023.
As of December 31, 2023, we had recorded valuation allowances of $4,550 primarily for certain domestic deferred tax assets, and certain domestic net operating losses, tax credit and interest carryforwards. To measure the valuation allowance, the Company estimated in what year each of its deferred tax assets and liabilities would reverse using systematic and logical methods to estimate the reversal patterns. Based on these methods, deferred tax liabilities are assumed to reverse and generate taxable income over the next 5 to 10 years while deferred tax assets related to pension and other postretirement benefit obligations are assumed to reverse and generate tax deductions over the next 15 to 20 years. The valuation allowance results from not having sufficient income from deferred tax liability reversals in the appropriate future periods to support the realization of deferred tax assets.
In the third quarter of 2024, we determined that earnings from our non-U.S. subsidiaries are no longer considered to be permanently reinvested. This resulted in a discrete income tax provision of $13 for the three months ended September 30, 2024.
Federal income tax audits have been settled for all years prior to 2021. The Internal Revenue Service is expected to begin the 2021-2023 federal tax audit in the third quarter of 2025. We are also subject to examination in major state and international jurisdictions for the 2010-2023 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.

Commercial Aircraft Programs
At September 30, 2024 and December 31, 2023, commercial aircraft programs inventory included the following amounts related to the 737 program: deferred production costs of $8,670 and $6,011 and unamortized tooling and other non-recurring costs of $879 and $792. At September 30, 2024, $9,505 of 737 deferred production costs, unamortized tooling and other non-recurring costs are expected to be recovered from units included in the program accounting quantity that have firm orders, and $44 is expected to be recovered from units included in the program accounting quantity that represent expected future orders.
At September 30, 2024 and December 31, 2023, commercial aircraft programs inventory included the following amounts related to the 777X program: $3,818 and $4,638 of work in process (including deferred production costs of $552 and $1,792) and $4,255 and $4,063 of unamortized tooling and other non-recurring costs. We expensed abnormal production costs of $442 during the nine months ended September 30, 2023. In the fourth quarter of 2023, the 777X program resumed production, and as a result, there were no abnormal production costs during the nine months ended September 30, 2024. During the third quarter of 2024, we determined that estimated costs to complete the 777X program plus the costs already included in 777X inventory exceed estimated revenues from the program. The resulting reach-forward loss of $2,608 was recorded as a reduction of deferred production costs. The level of profitability on the 777X program will be subject to a number of factors. These factors include aircraft certification requirements and timing, change incorporation on completed aircraft, production disruption due to labor instability (including the ongoing work stoppage) and supply chain disruption, customer delivery timing and negotiations, further production rate adjustments for the 777X or other commercial aircraft programs, and contraction of the accounting quantity. One or more of these factors could result in additional reach-forward losses in future periods.
At September 30, 2024 and December 31, 2023, commercial aircraft programs inventory included the following amounts related to the 787 program: deferred production costs of $12,452 and $12,384, supplier advances of $1,394 and $1,764, and unamortized tooling and other non-recurring costs of $1,402 and $1,480. At September 30, 2024, $11,403 of 787 deferred production costs, unamortized tooling and other non-recurring costs are expected to be recovered from units included in the program accounting quantity that have firm orders, and $2,451 is expected to be recovered from units included in the program accounting quantity that represent expected future orders. We expensed abnormal production costs of $209 and $937 during the nine months ended September 30, 2024 and 2023.
Commercial aircraft programs inventory included amounts credited in cash or other consideration (early issue sales consideration) to airline customers totaling $4,716 and $4,126 at September 30, 2024 and December 31, 2023.

Note 7 – Contracts with Customers
Unbilled receivables increased from $8,317 at December 31, 2023, to $9,356 at September 30, 2024, primarily driven by revenue recognized at BDS in excess of billings.
Advances and progress billings increased from $56,328 at December 31, 2023, to $57,931 at September 30, 2024, primarily driven by advances on orders received at Commercial Airplanes (BCA).
Revenues recognized during the nine months ended September 30, 2024 and 2023, from amounts recorded as Advances and progress billings at the beginning of each year were $11,804 and $11,602. Revenues recognized during the three months ended September 30, 2024 and 2023, from amounts recorded as Advances and progress billings at the beginning of each year were $3,927 and $3,717.

Note 10 – Liabilities, Commitments and Contingencies
737 MAX Customer Concessions and Other Considerations
During the first quarter of 2024, we recorded an earnings charge of $443, net of insurance recoveries, in connection with estimated considerations to customers for disruption related to the Alaska Airlines 737-9 accident and 737-9 grounding. This charge is reflected in the financial statements as a reduction to Sales of products.

Changes in estimates98 149 
Ending balance – September 30$875 $855 
The liabilities recorded represent our best estimate or the low end of a range of reasonably possible costs expected to be incurred to remediate sites, including operation and maintenance over periods of up to 30 years. It is reasonably possible that we may incur costs that exceed these recorded amounts because of regulatory agency orders and directives, changes in laws and/or regulations, higher than expected costs and/or the discovery of new or additional contamination. As part of our estimating process, we develop a range of reasonably possible alternate scenarios that includes the high end of a range of reasonably possible cost estimates for all remediation sites for which we have sufficient information based on our experience and existing laws and regulations. There are some potential remediation obligations where the costs of remediation cannot be reasonably estimated. At September 30, 2024 and December 31, 2023, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $997 and $1,030.

Commercial Aircraft Trade-In Commitments
In conjunction with signing definitive agreements for the sale of new aircraft, we have entered into trade-in commitments with certain customers that give them the right to trade in used aircraft at a specified price. The probability that trade-in commitments will be exercised is determined by using both quantitative information from valuation sources and qualitative information from other sources. The probability of
18

exercise is assessed quarterly, or as events trigger a change, and takes into consideration the current economic and airline industry environments. Trade-in commitments, which can be terminated by mutual consent with the customer, may be exercised only during the period specified in the agreement, and require advance notice by the customer.
Trade-in commitment agreements at September 30, 2024, have expiration dates from 2024 through 2030. At September 30, 2024 and December 31, 2023, total contractual trade-in commitments were $1,325 and $1,415. As of September 30, 2024 and December 31, 2023, we estimated it was probable we would be obligated to perform on certain of these commitments with net amounts payable to customers totaling $431 and $407 and the fair value of the related trade-in aircraft was $
