Boeing Company: 10-K Risk Factor Changes

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 15 15 15 Table of Contents Table of Contents water and waste requirements may drive increased costs to us and our suppliers and impact our production continuity and data facilities. 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.

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. 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 recent operational goals in areas of GHG emissions, energy, water and waste. If we fail to achieve or improperly report on our progress toward achieving our sustainability goals and commitments, the resulting negative publicity could adversely affect our reputation and/or our access to capital. 15 15 15 Table of Contents Table of Contents

We depend, in part, upon the issuance of debt to fund our operations and contractual commitments. As of December 31, 2023, our debt totaled $52.3 billion of which approximately $17.7 billion of principal payments on outstanding debt will become due over the next three years. In addition, as of December 31, 2023, our airplane financing commitments totaled $17.0 billion. If we require additional funding in order to pay off existing debt, address further impacts to our business related to market developments, fund outstanding financing commitments or meet other business requirements, our market liquidity may not be sufficient. These risks will be particularly acute if we are subject to further credit rating downgrades such as those we experienced in 2020. A number of factors could cause us to incur increased borrowing costs and to have greater difficulty accessing public and private markets for debt. These factors include disruptions or declines in the global capital markets and/or a decline in our financial performance, outlook or credit ratings and/or changes in demand for our products and services. The occurrence of any or all of these events may adversely affect our ability to fund our operations and contractual or financing commitments.

We depend, in part, upon the issuance of debt to fund our operations and contractual commitments. In addition, our debt balances have increased significantly since 2019, driven primarily by impacts related to the 737 MAX grounding and the COVID-19 pandemic, and we expect to continue to actively manage our liquidity. As of December 31, 2022, our debt totaled $57.0 billion of which approximately $14.5 billion of principal payments on outstanding debt will become due over the next three years. In addition, as of December 31, 2022, our airplane financing commitments totaled $16.1 billion. Our increased debt balance resulted in downgrades to our credit ratings in 2020, and our ratings remained unchanged in 2022 and 2021. If we require additional funding in order to pay off existing debt, address further impacts to our business related to market developments, fund outstanding financing commitments or meet other business requirements, our market liquidity may not be sufficient. These risks will be particularly acute if we are subject to further credit rating downgrades. A number of factors could cause us to incur increased borrowing costs and to have greater difficulty accessing public and private markets for debt.

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.

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. In addition, there continues to be uncertainty with respect to future acquisition priorities and program-level appropriations for the U.S. DoD and other government agencies (including NASA), including changes to national security and defense priorities, and tension between modernization investments, sustainment investments, and investments in new technologies or emergent capabilities. Future investment priority changes or budget cuts, including changes associated with the authorizations and appropriations process, could result in reductions, cancellations, and/or delays of existing contracts or programs or future program opportunities. Any of these impacts could have a material effect on our financial position, results of operations and/or cash flows. As a result of the significant ongoing uncertainty with respect to both U.S. defense spending and the evolving nature of the national security threat environment, we also expect the U.S. DoD to continue to emphasize affordability, innovation, cybersecurity and delivery of technical data and software in its procurement processes, including the implementation of cybersecurity compliance requirements on the Defense Industrial Base, for which the supply chain may not be fully prepared. If we and our suppliers 8 8 8 Table of Contents Table of Contents are unable to adjust to these changing acquisition priorities and policies, our revenues and market share could be impacted.

The timeliness of FY24 and future appropriations for government departments and agencies remains a recurrent risk. A lapse in appropriations for government departments or agencies would result in a full or partial government shutdown, which could impact the Company’s operations. Alternatively, Congress may fund government departments and agencies with one or more Continuing Resolutions; however, this would restrict the execution of certain program activities and delay new programs or competitions. In addition, long-term uncertainty remains with respect to overall levels of defense spending in FY24 and beyond. U.S. government discretionary spending, including defense spending, is likely to continue to be subject to pressure. There continues to be uncertainty with respect to future acquisition priorities and program-level appropriations for the U.S. DoD and other government agencies (including NASA), including changes to national security and defense priorities, and tension between modernization investments, sustainment investments, and investments in new technologies or emergent capabilities. Future investment priority changes or budget cuts, including changes associated with the authorizations and appropriations process, could result in reductions, cancellations, and/or delays of existing contracts or programs, or future program opportunities. Any of these impacts could have a material effect on the results of the Company’s financial position, results of operations and/or cash flows. 8 8 8 Table of Contents Table of Contents In addition, as a result of the significant ongoing uncertainty with respect to both U.S. defense spending and the evolving nature of the national security threat environment, we also expect the U.S. DoD to continue to emphasize affordability, innovation, cybersecurity and delivery of technical data and software in its procurement processes, including the implementation of cybersecurity compliance requirements on the Defense Industrial Base, for which the supply chain may not be fully prepared. We and our suppliers will need to continue to adjust successfully to these changing acquisition priorities and policies or our revenues and market share could be impacted.

The commercial aircraft business is extremely complex, involving extensive coordination and integration with U.S. and non-U.S. suppliers, highly-skilled labor performed by thousands of employees of ours and other partners, and stringent and evolving regulatory requirements and performance and reliability standards. We have experienced and may continue to experience production quality issues, including in our supply chain. On January 10, 2024, the FAA notified us that it has initiated an investigation into our quality control system. This was followed by the FAA announcing actions to increase its oversight of us, including conducting (1) an audit involving the 737-9 production line and suppliers to evaluate compliance with approved quality procedures, (2) increased monitoring of 737-9 in-service events, and (3) an assessment of safety risks around delegated authority and quality oversight, and examination of options to move these functions under independent third parties. On January 24, 2024, the FAA stated that it will not approve production rate increases or additional production lines for the 737 MAX until it is satisfied that we are in full compliance with required quality control procedures. We are currently unable to reasonably estimate what impact the January 5, 2024 Alaska Airlines accident and the related FAA actions will have on our financial position, results of operations and cash flows. 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. A number of our customers have contractual remedies, including compensation for late deliveries or rights to reject individual airplane deliveries based on delivery delays. Delays on the 737, 777X and 787 programs have resulted in, and may continue to result in, customers having the right to terminate orders, be compensated for late deliveries and/or substitute orders for other Boeing aircraft. We must minimize disruption caused by production changes, achieve operational stability and implement productivity improvements in order to meet customer demand and maintain our profitability. We have previously announced plans to adjust production rates on several of our commercial aircraft programs. In addition, we continue to seek opportunities to reduce the costs of building our aircraft, including working with our suppliers to reduce supplier costs, identifying and implementing productivity improvements and optimizing how we manage inventory. If production rate changes at any of our commercial aircraft assembly facilities are delayed or create significant disruption to our production system, or if our suppliers cannot timely deliver components that comply with design specifications to us at the cost and rates necessary to achieve our targets, we may be unable to meet delivery schedules and/or the financial performance of one or more of our programs may suffer. 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 7 7 7 Table of Contents Table of Contents 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.

The commercial aircraft business is extremely complex, involving extensive coordination and integration with U.S and non-U.S. suppliers, highly-skilled labor performed by thousands of employees of ours and other partners, and stringent and evolving regulatory requirements and performance and reliability standards. The FAA has been working to implement safety reforms such as the 2018 FAA Reauthorization Act and the 2020 Aircraft Certification, Safety and Accountability Act (ACSAA). One of these, section 116 of the ACSAA prohibited the FAA from issuing a type certificate to aircraft after December 27, 2022 unless the aircraft’s flight crew alerting system met certain specifications. The Consolidated Appropriations Act, 2023 amended Section 116 of the ACSAA, such that applications for original or amended type certifications that were submitted to the FAA prior to December 27, 2020, including those of the 737-7 and 737-10, are no longer subject to the crew alerting specifications of Section 116. Additionally, beginning one year after the FAA issues the type certificate for the 737-10, any new 737 MAX aircraft must include certain safety enhancements to be issued an original airworthiness certification by the FAA. These enhancements are included in Boeing’s application for the certification for the 737-10, and the sufficiency of these enhancements will be determined by the FAA. Beginning three years after the issuance of a type certificate for the 737-10, all previously delivered 737 MAX aircraft must be retrofitted with these safety enhancements. As the holder of the type certificate, Boeing is required to bear any costs of these safety enhancement retrofits. We have provisioned for the estimated costs associated with the safety enhancements and do not expect those costs to be material. If we experience delays in achieving certification and/or incorporating safety enhancements, future revenues, cash flows and results of operations could be adversely impacted. Comparable agencies in other countries may adopt similar changes. To the extent the FAA or similar regulatory agencies outside the U.S. implement more stringent regulations, we may incur additional compliance costs. In addition, the introduction of new aircraft programs and/or derivatives, such as the 777X, 737-7 and 737-10, involves increased risks associated with meeting development, testing, certification and production schedules. In addition, we have experienced production quality issues, including in our supply chain, which have contributed to lower 787 deliveries, including a suspension of 787 deliveries from May 2021 to August 2022. We continue to conduct inspections and rework on built and stored 787 aircraft. A number of our customers have contractual remedies, including compensation for late deliveries or rights to reject individual airplane deliveries based on delivery delays. Delays on the 737, 777X and 787 programs have resulted in, and may continue to result in, customers having the right to terminate orders, be compensated for late deliveries and/or substitute orders for other Boeing aircraft. We must minimize disruption caused by production changes, achieve operational stability and implement productivity improvements in order to meet customer demand and maintain our profitability. We have previously announced plans to adjust production rates on several of our commercial aircraft programs. The 787 program is currently producing at low rates and we expect to gradually increase to 5 per month in 2023. Production of the 777X is currently paused and is expected to resume in 2023. The 737 program has experienced operational and supply chain challenges stabilizing production at 31 per month. We plan to gradually increase 737 production rates based on market demand and supply chain capacity. In addition, we continue to seek opportunities to reduce the costs of building our aircraft, including working with our suppliers to reduce supplier costs, identifying and implementing productivity improvements and optimizing how we manage inventory. If production rate changes at any of our 7 7 7 Table of Contents Table of Contents commercial aircraft assembly facilities are delayed or create significant disruption to our production system, or if our suppliers cannot timely deliver components to us at the cost and rates necessary to achieve our targets, we may be unable to meet delivery schedules and/or the financial performance of one or more of our programs may suffer.

We and our suppliers are experiencing supply chain disruptions as a result of the lingering impacts of COVID-19, global supply chain constraints, and labor instability. We and our suppliers are also experiencing inflationary pressures. We continue to monitor the health and stability of the supply chain as we ramp up production. These factors have reduced overall productivity and adversely impacted 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 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. A cyber-related attack or security breach, whether experienced directly or through our supply chain or third party-service providers, could, among other serious consequences, result in loss of intellectual property; allow unauthorized access to or cause the publication of various categories of sensitive, proprietary or customer data; cause disruption or degradation of our business operations; compromise our products or services; and/or result in reputational harm. To address these risks, we maintain an extensive network of technical security controls, policy enforcement mechanisms, monitoring systems, contractual arrangements, tools and related services, and management and Board oversight. While these measures are designed to prevent, detect, respond to, and mitigate unauthorized activity, there is no guarantee that they will be sufficient to prevent or mitigate the risk of a cyber-related attack or incident, or allow us to detect, report or respond adequately in a timely manner. 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. In addition, we manage information and information technology systems for certain customers and suppliers. Many of these customers and suppliers face similar security threats. If we were unable to protect against the unauthorized access, release or corruption of our customers’ or suppliers’ confidential, classified or personally identifiable information, we could suffer a loss of business, face regulatory actions or face financial or other losses that could materially affect our business strategy, results of operations or financial condition.

To address these risks, we maintain an extensive network of technical security controls, policy enforcement mechanisms, monitoring systems and management oversight. We also have established a Cybersecurity Governance Council to strengthen governance and coordination of cybersecurity activities. While these measures are designed to prevent, detect and respond to unauthorized activity, there is no guarantee that they will be sufficient to prevent or mitigate the risk of a cyberattack or the potentially serious reputational, operational, or financial impacts that may result. In November 2022, we discovered a cybersecurity incident that impacted certain systems of Jeppesen, a wholly owned Boeing subsidiary that provides flight planning and navigation services. We determined that the incident posed no risk to flight safety. We promptly notified law enforcement, regulatory authorities and customers, launched an investigation, and took additional steps to protect the integrity of our systems. While this incident has not had a material impact on us, future incidents like this one could have material impact on our business, operations, and reputation. In addition, we manage information and information technology systems for certain customers and/or suppliers. Many of these customers and/or suppliers face similar security threats. If we were unable to protect against the unauthorized access, release and/or corruption of our customers’ and/or suppliers’ confidential, classified or personally identifiable information, our reputation could be damaged, and/or we could face financial or other losses.
