Previous wording

Market conditions have a significant impact on demand for our commercial aircraft and related services. The commercial aircraft market is predominantly driven by long-term trends in airline passenger and cargo traffic. The principal factors underlying long-term traffic growth are sustained economic growth and political stability both in developed and emerging markets. Demand for our commercial aircraft is further influenced by airline profitability, availability of aircraft financing, world trade policies, government-to-government relations, technological advances, price and other competitive factors, fuel prices, terrorism, pandemics, epidemics and environmental regulations. Historically, the airline industry has been cyclical and very competitive and has experienced significant profit swings and constant challenges to be more cost competitive. Significant deterioration in the global economic environment, the airline industry generally or the financial stability of one or more of our major customers could result in fewer new orders for aircraft or services, or could cause customers to seek to postpone or cancel contractual orders and/or payments to us, which could result in lower revenues, profitability and cash flows and a reduction in our contractual backlog. In addition, because our commercial aircraft backlog consists of aircraft scheduled for delivery over a period of several years, any of these macroeconomic, industry or customer impacts could unexpectedly affect deliveries over a long period.

The commercial aircraft market is predominantly driven by long-term trends in airline passenger and cargo traffic. The principal factors underlying long-term traffic growth are sustained economic growth and political stability in both developed and emerging markets. Demand for our commercial aircraft is further influenced by additional factors including airline profitability, availability of aircraft financing, trade policies, geopolitics, technological advances, price and other competitive factors, fuel prices, inflationary pressures, terrorism, pandemics, epidemics, sustainability-related preferences, environmental regulations, and reputational factors.

Previous wording

We enter into firm fixed-price aircraft sales contracts with indexed price escalation clauses, which could subject us to losses if we have cost overruns or if increases in our costs exceed the applicable escalation rate. Commercial aircraft sales contracts are often entered into years before the aircraft are delivered. In order to help account for economic fluctuations between the contract date and delivery date, aircraft pricing generally consists of a fixed amount as modified by price escalation formulas derived from labor, commodity and other price indices. Our revenue estimates are based on current expectations with respect to these escalation formulas, but the actual escalation amounts are outside of our control. Escalation factors can fluctuate significantly from period to period. Changes in escalation amounts can significantly impact revenues and operating margins in our BCA business.

We derive a significant portion of our revenues from a limited number of commercial airlines. We can make no assurance that any customer will exercise purchase options, fulfill existing purchase commitments or purchase additional products or services from us. In addition, fleet decisions, airline consolidations or financial challenges involving any of our major commercial airline customers could significantly reduce our revenues and limit our opportunity to generate profits from those customers. Airlines also are experiencing increased fuel and other costs, and the global economy has experienced high inflation.

Previous wording

The introduction of new aircraft programs and/or derivatives, such as the 777X, 737-7 and 737-10, involves risks associated with meeting development, testing, certification and production schedules. We are following the lead of the FAA as we work through the certification process, and the FAA will ultimately determine the timing of certification and entry into service. In addition, the development schedules of the 737-7 and 737-10 could be impacted by actions resulting from the Alaska Airlines accident. If we experience delays in achieving certification and/or incorporating safety enhancements, our financial position, results of operations and cash flows would be adversely impacted.

There have been delays on each of these development programs and if we experience additional delays in achieving certification, our financial position, results of operations and cash flows would be adversely impacted.

Previous wording

Operational challenges impacting the production system for one or more of our commercial aircraft programs could result in additional production delays and/or failure to meet customer demand for new aircraft, either of which would negatively impact our revenues and operating margins. Our commercial aircraft production system is extremely complex. Operational issues, including delays or defects in supplier components, failure to meet internal performance plans, or delays or failures to achieve required regulatory approval, could result in additional out-of-sequence work and increased production costs, as well as delayed deliveries to customers, impacts to aircraft performance and/or increased warranty or fleet support costs. We and our suppliers are experiencing supply chain disruptions and constraints, labor instability and inflationary pressures. We continue to monitor the health and stability of the supply chain. These factors have and may continue to reduce overall productivity and adversely impact our financial position, results of operations and cash flows.

If our commercial aircraft fail to satisfy performance and reliability requirements and/or potentially required sustainability standards, we could face additional costs and/or lower revenues. Developing and manufacturing commercial aircraft that meet or exceed our performance and reliability standards and/or potentially required sustainability standards, as well as those of customers and regulatory agencies, can be costly and technologically challenging. These challenges are particularly significant with newer aircraft programs. Any failure of any Boeing aircraft to satisfy performance or reliability requirements could result in disruption to our operations, higher costs and/or lower revenues.

We derive a substantial portion of our revenue from the U.S. government, primarily from defense related programs with the United States Department of Defense (U.S. DoD). Levels of U.S. defense spending are very difficult to predict and may be impacted by numerous factors such as the evolving nature of the national security threat environment, U.S. national security strategy, U.S. foreign policy, the domestic political environment, macroeconomic conditions and the ability of the U.S. government to enact relevant legislation such as authorization and appropriations bills. The government may also constrain discretionary spending by instituting enforceable spending caps.

The timeliness of annual appropriations for U.S. government departments and agencies remains a recurrent risk. Congress may fund government departments and agencies with one or more continuing resolutions, which could delay new programs or competitions and/or negatively impact the execution of certain program activities. A lapse in appropriations for government departments or agencies would result in a full or partial government shutdown, which could impact our operations. In the event of a prolonged shutdown, requirements to furlough employees in the U.S. DoD, the Department of Transportation, including the FAA, or other government agencies could result in payment delays, impair our ability to deliver commercial airplanes or perform work on existing contracts, delays in the certification of new aircraft or otherwise impact our operations, negatively impact future orders, and/or cause other disruptions or delays. There is uncertainty regarding which government functions would shut down or continue operations during a lapse in appropriations, and corresponding uncertainty regarding the extent or magnitude of potential impacts to our operations. For additional information on U.S. government appropriations and budgets, see “Management’s Discussion & Analysis - Additional Considerations - U.S. Government Funding” on page 28 of this Form 10-K.

We rely on other companies, including U.S. and non-U.S. subcontractors and suppliers, to provide and produce raw materials, integrated components and sub-assemblies, and production commodities and to perform some of the services that we provide to our customers. Many of our suppliers are experiencing inflationary pressures, as well as resource constraints and disruptions due to production quality issues, global supply chain constraints, and labor instability. If one or more of our suppliers or subcontractors continue to experience financial difficulties, delivery delays or other performance problems, we may be unable to meet commitments to our customers and our financial position, results of operations and cash flows may continue to be adversely impacted. In addition, if one or more of the raw materials on which we depend (such as aluminum, titanium or composites) becomes unavailable to us or our suppliers, or is available only at very high prices, we may be unable to deliver one or more of our products in a timely fashion or at budgeted costs. We continue proactively working to ensure sufficient material and parts to avoid potential near-term production disruptions, while also working to mitigate the risk of future impacts from disruptions to our supply chain. In some instances, we depend upon a single source of supply. Any service disruption from one of these suppliers, either due to circumstances beyond the supplier’s control, such as geopolitical developments, or as a result of performance problems or financial difficulties, could have a material adverse effect on our ability to meet commitments to our customers or increase our operating costs.

Some of our and our suppliers’ workforces are represented by labor unions, which may lead to work stoppages.

Current wording

Some of our and our suppliers’ workforces are represented by labor unions. Work stoppages by our employees have adversely affected and could continue to adversely affect our business, financial condition, results of operations and/or cash flows. Future work stoppages by our or our suppliers’ employees could also adversely impact our business.

Previous wording

Approximately 57,000 employees, which constitute 33% of our total workforce, were union represented as of December 31, 2023 under collective bargaining agreements with varying durations and expiration dates. For additional information on our principal collective bargaining agreements, see “Business– Human Capital” on page 2 of this Form 10-K. We experienced a work stoppage in 2008 when a labor strike halted commercial aircraft and certain BDS program production. We may experience additional work stoppages in the future, which could adversely affect our business. We cannot predict how stable our union relationships, currently with 10 U.S. labor organizations and 4 non-U.S. labor organizations, will be or whether we will be able to meet the unions’ requirements without impacting our financial condition. The unions may also limit our flexibility in managing our workforce and operations. Union actions at suppliers can also affect us. Work stoppages and instability in our union relationships could delay the production and/or development of our products, which could strain relationships with customers and result in lower revenues.

With respect to each of our commercial aircraft programs, inventoriable production costs (including overhead), program tooling and other non-recurring costs and routine warranty costs are accumulated and charged as cost of sales by program instead of by individual units or contracts. A program consists of the estimated number of units (accounting quantity) of a product to be produced in a continuing, long-term production effort for delivery under existing and anticipated contracts limited by the ability to make reasonably dependable estimates. To establish the relationship of sales to cost of sales, program accounting requires estimates of (a) the number of units to be produced and sold in a program, (b) the period over which the units can reasonably be expected to be produced and (c) the units’ expected sales prices, production costs, program tooling and other non-recurring costs, and routine warranty costs for the total program. Several factors determine accounting quantity, including firm orders, letters of intent from prospective customers and market studies. Changes to customer or model mix, production costs and rates, learning curve, changes to price escalation indices, costs of derivative aircraft, supplier performance, customer and supplier negotiations/settlements, supplier claims and/or certification issues can impact these estimates. In addition, on development programs such as the 777X, 737-7 and 737-10 we are subject to risks with respect to the timing and conditions of aircraft certification, including potential gaps between when aircraft are certified in various jurisdictions, changes in certification processes and our estimates with respect to the timing of future certifications, which could have an impact on overall program status. Any such change in estimates relating to program accounting may adversely affect future financial performance.

As part of our business strategy, we may merge with or acquire businesses and/or form joint ventures and strategic alliances. Whether we realize the anticipated benefits from these acquisitions and related activities depends, in part, upon our ability to integrate the operations of the acquired business, the performance of the underlying product and service portfolio, and the performance of the management team and other personnel of the acquired operations. Accordingly, our financial results could be adversely affected by unanticipated performance issues, legacy liabilities, transaction-related charges, amortization of expenses related to intangibles, charges for impairment of long-term assets, credit guarantees, partner performance and indemnifications. Consolidations of joint ventures could also impact our reported results of operations or financial position. While we believe that we have established appropriate and adequate procedures and processes to mitigate these risks, there is no assurance that these transactions will be successful. We also may make strategic divestitures from time to time. These transactions may result in continued financial involvement in the divested businesses, such as through guarantees or other financial arrangements, following the transaction. Nonperformance by those divested businesses could affect our future financial results through additional payment obligations, higher costs or asset write-downs.

Our BDS and BGS defense businesses generated approximately 58% and 65% of their 2023 revenues from fixed-price contracts. While fixed-price contracts enable us to benefit from performance improvements, cost reductions and efficiencies, they also subject us to the risk of reduced margins or incurring losses if we are unable to achieve estimated costs and revenues. If our estimated costs exceed our estimated price, we recognize reach-forward losses which can significantly affect our reported results. For example, during the year ended December 31, 2023, BDS recorded $1,585 million of additional losses on its five most significant fixed-price development programs (Commercial Crew, KC-46A Tanker, MQ-25, T-7A Red Hawk, and VC-25B Presidential Aircraft). We continue to experience production disruptions and inefficiencies due to technical challenges, supplier disruption and factory performance. These factors have contributed to significant earnings charges on a number of fixed-price development programs which are expected to adversely affect cash flows in future periods, and may result in future earnings charges and adverse cash flow effects. Production and supplier disruptions, inefficiencies, technical challenges, quality issues and labor instability also contributed to lower earnings on fixed-price production programs in 2023. New programs could also have risk for reach-forward loss upon contract award and during the period of contract performance. The long-term nature of many of our contracts makes the process of estimating costs and revenues on fixed-price contracts inherently risky. Fixed-price contracts often contain price incentives and penalties tied to performance, which can be difficult to estimate and have significant impacts on margins. In addition, some of our contracts have specific provisions relating to cost, schedule and performance.

Current wording

Our BDS and BGS defense businesses generated approximately 54% and 63% of their 2024 revenues from fixed-price contracts. Fixed-price development contracts subject us to the risk of reduced margins or incurring losses if we are unable to achieve estimated costs and revenues. If our estimated costs exceed our estimated price, we recognize reach-forward losses which can significantly affect our reported results. For example, during the year ended December 31, 2024, BDS recorded $5.0 billion of additional losses on its five most significant fixed-price development programs (KC-46A Tanker, T-7A Red Hawk, Commercial Crew, VC-25B Presidential Aircraft, and MQ-25). We continue to experience production disruptions and inefficiencies due to technical challenges, supplier disruption and factory performance. These factors have contributed to significant earnings charges on a number of fixed-price development programs which are expected to adversely affect cash flows in future periods, and may result in future earnings charges and adverse cash flow effects. Higher supplier pricing, the IAM 751 work stoppage, higher labor costs and an inexperienced workforce also contributed to earnings charges and lower earnings in 2024. New programs could also have risk for reach-forward loss upon contract award and during the period of contract performance.

Our BDS and BGS defense businesses generated approximately 42% and 35% of their 2023 revenues from cost-type contracting arrangements. Some of these are development programs that have complex design and technical challenges. These cost-type programs typically have award or incentive fees that are subject to uncertainty and may be earned over extended periods. In these cases the associated financial risks are primarily reduced award or incentive fees, lower profit rates or program cancellation if cost, schedule or technical performance issues arise. Examples of programs with cost-type contracts include Ground-based Midcourse Defense, Proprietary and Space Launch System programs.

We rely extensively on information technology systems and networks to operate our company and meet our business objectives. We face various cyber security threats, including attempts to gain unauthorized access to our systems and networks, denial-of-service attacks, threats to our information technology infrastructure, ransomware and phishing attacks, and attempts to gain unauthorized access to our company-, customer- and employee-sensitive information. These threats come from a variety of actors some of which are highly organized and sophisticated such as nation-state actors and criminal enterprises. In addition, the techniques used in cyberattacks evolve rapidly, including from emerging technologies, such as advanced forms of automation and artificial intelligence. As cyber threats increase in volume and sophistication, the risk to the security of these systems and networks – and to the confidentiality, integrity, and availability of the data they house – continues to evolve, requiring constant vigilance and concerted, company-wide risk management efforts.

We have experienced, and may in the future experience, whether directly or through our supply chain, third-party service providers or other channels, cybersecurity incidents. While prior cyber-related attacks and incidents (including those at our wholly-owned subsidiaries Boeing Distribution, Inc. in 2023 and Jeppesen Inc. in 2022) have not materially affected our business strategy, results of operations or financial condition, there is no guarantee that a future cyber-related attack or incident would not result in significant operational, regulatory, or financial impacts that could materially affect our business strategy, results of operations or financial condition.

Previous wording

We are involved in a number of litigation matters. These matters may divert financial and management resources that would otherwise be used to benefit our operations. No assurances can be given that the results of these matters will be favorable to us. An adverse resolution of any of these lawsuits, or future lawsuits, could have a material impact on our financial position and results of operations. In addition, we are subject to extensive regulation under the laws of the United States and its various states, as well as other jurisdictions in which we operate and/or market our products. As a result, we are sometimes subject to government inquiries and investigations due, among other things, to our business relationships with the U.S. government, the heavily regulated nature of our industry, and in the case of environmental proceedings, our current or past ownership of certain property. Any such inquiry or investigation could result in an adverse ruling against us, which could have a material impact on our financial position, results of operations and/or cash flows.

Previous wording

We are subject to various U.S. federal, state, local and non-U.S. laws and regulations related to environmental protection, including the discharge, treatment, storage, disposal and remediation of pollutants, hazardous substances and wastes. We could incur substantial costs, including cleanup costs, fines and civil or criminal sanctions, as well as third-party claims for property damage or personal injury, if we were to violate or become liable under environmental laws or regulations. In some cases, we are subject to such costs due to environmental impacts attributable to our current or past manufacturing operations or the operations of companies we have acquired. In other cases, we are subject to such costs due to an indemnification agreement between us and a third party relating to such environmental liabilities. In all cases, our current liabilities and ongoing cost assessments are based on current laws and regulations. New laws and regulations, more stringent enforcement of existing laws and regulations, the discovery of previously unknown contamination or the imposition of new remediation requirements could result in additional costs. For additional information relating to environmental contingencies, see Note 13 to our Consolidated Financial Statements.

Increasing stakeholder environmental, social and governance (ESG) expectations, physical and transition risks associated with climate change, emerging ESG regulation, contractual requirements, and policy requirements may pose risk to our market outlook, brand and reputation, financial outlook, cost of capital, global supply chain and production continuity, which may impact our ability to achieve long-term business objectives. Changes in environmental and climate change laws or regulations could lead to additional operational restrictions and compliance requirements upon us or our products, require new or additional investments in production systems or product designs, result in additional carbon offset investments or otherwise negatively impact our business and/or competitive position. Increasingly stringent aircraft performance standards and requirements including but not limited to manufacturing and product air pollutant emissions, potential carbon pricing mechanisms, and sustainability disclosure requirements in the U.S. and other jurisdictions may result in increased costs or reputational risks and could limit our ability to manufacture and/or market certain of our products at acceptable costs, or at all. For example, certain jurisdictions including the State of California and the European Union have enacted legislation which would require more stringent greenhouse gas emissions and climate risk reporting. Physical impacts of climate change, increasing global chemical restrictions and bans, and water and waste requirements may drive increased costs to us and our suppliers and impact our production continuity and data facilities.

Previous wording

Finally, from time to time, in alignment with our sustainability priorities, we establish and publicly announce goals and commitments to improve our environmental performance, such as our operational goals in areas of GHG emissions, energy, water and waste. If we fail to achieve or inadequately report our progress toward achieving such goals and commitments, the resulting negative publicity could adversely affect our reputation and/or our access to capital.

Current wording

From time to time, in alignment with our sustainability priorities, we establish and publicly announce goals and commitments to improve our environmental performance, within our products and/or operations. If we fail to achieve or inadequately report our progress toward achieving such goals and commitments, the resulting negative publicity could adversely affect our reputation and/or our access to capital.

Previous wording

We may be unable to obtain debt to fund our operations and contractual commitments at competitive rates, on commercially reasonable terms or in sufficient amounts.

Current wording

We depend, in part, on our ability to successfully access the capital and financial markets to fund our operations and contractual commitments. Net cash used by operating activities for the year ended December 31, 2024 was $12.1 billion and we expect negative operating cash flows to continue in future quarters as we work to ramp up commercial airplanes production. As of December 31, 2024, our debt totaled $53.9 billion, of which approximately $13.6 billion of principal payments on outstanding debt are scheduled to become due over the next three years, and our airplane financing commitments totaled $17.1 billion. In addition, we will assume Spirit’s net debt upon the closing of our acquisition of Spirit, which is expected to occur later this year. We also expect to require up to $345 million of cash per year for the payment of dividends on the outstanding shares of our 6.00% Series A Mandatory Convertible Preferred Stock (Mandatory convertible preferred stock), through the mandatory conversion date of October 15, 2027. Dividends accumulate at a rate per annum equal to 6.00% on the liquidation preference thereof, which is $1,000.00 per share, payable when, as and if declared by our Board of Directors. The dividends, if declared, can be paid in cash, or subject to certain limitations, in shares of our common stock, or a combination of both. Any unpaid dividends will continue to accumulate. If dividends have not been declared and paid for six or more dividend periods, whether or not for consecutive dividend periods, the holders of such shares of Mandatory convertible preferred stock, will be entitled at our next annual or special meeting of shareholders to vote for the election of two additional members of our Board of Directors, subject to certain limitations. If we require additional capital to support our operations, pay off existing debt, address impacts to our business related to market developments, fund dividend payments or outstanding financing commitments or meet other business requirements, we may need to refinance or restructure our debt, reduce or delay capital investments, or issue equity, equity-linked or debt securities, and these activities could have terms that are unfavorable or could be dilutive. If we are unable to access the capital or financial markets at competitive rates, on terms acceptable to us or in sufficient amounts, or if we experience an increase in our borrowing costs or otherwise fail to manage our liquidity effectively, our business, financial position and results of operations would be adversely affected.

Previous wording

Many of our employees have earned benefits under defined benefit pension plans. Potential pension contributions include both mandatory amounts required under the Employee Retirement Income Security Act and discretionary contributions to improve the plans' funded status. The extent of future contributions depends heavily on market factors such as the discount rate and the actual return on plan assets. We estimate future contributions to these plans using assumptions with respect to these and other items. Changes to those assumptions could have a significant effect on future contributions as well as on our annual pension costs and/or result in a significant change to shareholders' equity. For U.S. government contracts, we allocate pension costs to individual contracts based on U.S. Cost Accounting Standards, which can also affect contract profitability. We also provide other postretirement benefits to certain of our employees, consisting principally of health care coverage for eligible retirees and qualifying dependents. Our estimates of future costs associated with these benefits are also subject to assumptions, including estimates of the level of medical cost increases. For a discussion regarding how our financial statements can be affected by pension and other postretirement plan accounting policies, see “Management's Discussion and Analysis – Critical Accounting Estimates – Pension Plans” on pages 47 - 48 of this Form 10-K. Although under Generally Accepted Accounting Principles in the United States of America (GAAP) the timing of periodic pension and other postretirement benefit expense and plan contributions are not directly related, the key economic factors that affect GAAP expense would also likely affect the amount of cash or stock we would contribute to our plans.

A significant portion of our customer financing portfolio, which is comprised of financing receivables and operating lease equipment, is concentrated among certain customers and in distinct geographic regions. Our portfolio is also concentrated by varying degrees across Boeing aircraft product types, most notably 717 aircraft, and among customers that we believe have less than investment-grade credit. If one or more customers holding a significant portion of our portfolio assets experiences financial difficulties or otherwise defaults on or does not renew its leases with us at their expiration, and we are unable to redeploy the aircraft on reasonable terms, or if the types of aircraft that are concentrated in our portfolio suffer greater than expected declines in value, our financial position, results of operations and/or cash flows could be materially adversely affected.
