BOEING CO

Overview

On January 5, 2024, an Alaska Airlines 737-9 flight made an emergency landing after a mid-exit door plug detached in flight. Following the accident, the Federal Aviation Administration (FAA) grounded and required inspections of all 737-9 aircraft with a mid-exit door plug, which constituted the large majority of the approximately 220 737-9 aircraft in the in-service fleet. On January 24, 2024, the FAA approved an enhanced maintenance and inspection process that was required to be performed on each of the grounded 737-9 aircraft. Our 737-9 operators returned their fleets to service in the first quarter. All 737-9 aircraft in production are undergoing this same enhanced inspection process prior to delivery.

The Alaska Airlines accident and the resulting actions we are taking, including slowing production, to improve compliance with our manufacturing quality control requirements have significantly impacted our financial position, results of operations and cash flows during the first quarter of 2024.

Consolidated Results of Operations and Financial Condition

Consolidated Results of Operations

The following table summarizes key indicators of consolidated results of operations:

(1)These measures exclude certain components of pension and other postretirement benefit expense. See pages 43-44 for important information about these non-GAAP measures and reconciliations to the most directly comparable GAAP measures.

The following table summarizes Revenues:

Revenues for the three months ended March 31, 2024 decreased by $1,352 million compared with the same period in 2023 driven by lower revenues at Commercial Airplanes (BCA), partially offset by higher revenues at Defense, Space & Security (BDS) and Global Services (BGS). BCA revenues decreased by $2,051 million primarily driven by lower 737 deliveries and 737-9 customer considerations. BDS revenues increased by $411 million primarily due to higher volume on weapons and proprietary programs and MQ-25 contract modifications in 2024, partially offset by the U.S. Air Force (USAF) KC-46A Tanker Lot 9 award in 2023. BGS revenues increased by $325 million primarily due to higher commercial services revenue.

Revenues will continue to be significantly impacted until the global supply chain stabilizes, labor instability diminishes, and deliveries ramp up.

Loss from Operations

The following table summarizes Loss from operations:

• The FAS/CAS service cost adjustment represents the difference between the FAS pension and postretirement service costs calculated under GAAP and costs allocated to the business segments.

** Core operating loss is a Non-GAAP measure that excludes the FAS/CAS service cost adjustment. See pages 43-44.

Loss from operations for the three months ended March 31, 2024 decreased by $63 million compared with the same period in 2023. BDS earnings from operations increased by $363 million compared to the same period in 2023 primarily due to lower charges in 2024 on major fixed-price development programs of $92 million, revenue growth on weapons and proprietary programs, and improved performance across other programs that were more adversely affected by labor instability and supply chain performance in the prior year. BGS earnings from operations increased by $69 million primarily due to higher commercial services revenue, partially offset by lower government services performance. BCA loss from operations increased by $528 million reflecting lower 737 deliveries and 737-9 customer considerations, partially offset by lower abnormal production costs. Loss from operations on Unallocated items, eliminations and other decreased by $148 million compared with the same period in 2023 primarily due to decreases in eliminations and other unallocated items and share based plans expense.

Core operating loss for the three months ended March 31, 2024 decreased by $52 million compared with the same period in 2023, primarily due to changes in Loss from operations as described above.

For information related to Postretirement Plans, see Note 11 to our Condensed Consolidated Financial Statements.

Unallocated Items, Eliminations and Other

The most significant items included in Unallocated items, eliminations and other (expense)/income are shown in the following table:

Share-based plans expense for the three months ended March 31, 2024 decreased by $62 million compared with the same period in 2023 primarily due to fewer outstanding share-based awards in 2024.

Deferred compensation expense for the three months ended March 31, 2024 decreased by $24 million compared with the same period in 2023 primarily driven by changes in our stock price.

Research and development expense for the three months ended March 31, 2024 was largely unchanged compared with the same period in 2023.

Eliminations and other unallocated items expense for the three months ended March 31, 2024 decreased by $75 million compared with the same period in 2023 due to a decrease in environmental remediation expense.

Other Earnings Items

Other income, net for the three months ended March 31, 2024 remained relatively consistent compared with the same period in 2023. For information on changes related to non-operating pension and postretirement expenses, see Note 11 to our Condensed Consolidated Financial Statements.

Interest and debt expense for the three months ended March 31, 2024 was lower compared with the same period in the prior year primarily as a result of lower average debt balances.

For additional discussion related to Income Taxes, see Note 3 to our Condensed Consolidated Financial Statements.

Total Costs and Expenses (“Cost of Sales”)

Cost of sales, for both products and services, consists primarily of raw materials, parts, sub-assemblies, labor, overhead and subcontracting costs. Our BCA segment predominantly uses program accounting to account for cost of sales. Under program accounting, cost of sales for each commercial aircraft program equals the product of (i) revenue recognized in connection with customer deliveries and (ii) the estimated cost of sales percentage applicable to the total remaining program. For long-term contracts, the amount reported as cost of sales is recognized as incurred. Substantially all contracts at our BDS segment and certain contracts at our BGS segment are long-term contracts with the U.S. government and other customers that generally extend over several years. Cost of sales for commercial spare parts is recorded at average cost.

The following table summarizes cost of sales:

Cost of sales for the three months ended March 31, 2024 decreased by $1,305 million, or 8% compared with the same periods in 2023, primarily due to lower revenues at BCA, partially offset by higher revenues at BDS and BGS. Cost of sales as a percentage of Revenues remained largely consistent during the three months ended March 31, 2024 compared with the same period in 2023.

Research and Development

Research and development expense, net is summarized in the following table:

Research and development expense increased by $127 million during the three months ended March 31, 2024 compared to the same period in 2023. The increase at BCA is primarily due to higher spending on the 777X program.

Backlog

Contractual backlog of unfilled orders excludes purchase options, announced orders for which definitive contracts have not been executed, orders where customers have the unilateral right to terminate, and unobligated U.S. and non-U.S. government contract funding. The increase in contractual backlog during the three months ended March 31, 2024 was primarily due to increases in BCA and BDS backlog. We may experience reductions to backlog and/or significant order cancellations due to production disruptions and/or further delays to entry into service of the 777X, 737-7 and/or 737-10.

Unobligated backlog includes U.S. and non-U.S. government definitive contracts for which funding has not been authorized. Unobligated backlog was largely unchanged during the three months ended March 31, 2024.

Global Trade We continually monitor the global trade environment in response to geopolitical economic developments, as well as changes in tariffs, trade agreements, or sanctions that may impact the Company.

The current state of U.S.-China relations remains an ongoing watch item. Since 2018, the U.S. and China have imposed tariffs on each other’s imports. Certain aircraft parts and components that Boeing procures are subject to these tariffs. We are mitigating import costs through Duty Drawback Customs procedures. China is a significant market for commercial aircraft and we have long-standing relationships with our Chinese customers, who represent a key component of our commercial aircraft backlog. Overall, the U.S.-China trade relationship remains stalled as economic and national security concerns continue to be a challenge.

Beginning in June 2018, the U.S. Government imposed tariffs on steel and aluminum imports. In response to these tariffs, several major U.S. trading partners have imposed, or announced their intention to impose, tariffs on U.S. goods. The U.S. has subsequently reached agreements with Mexico, Canada, Japan, the United Kingdom, and the European Union to ease or remove tariffs on steel and/or aluminum. We continue to monitor the potential for any extra costs that may result from the remaining global tariffs.

We are complying with all U.S. and other government export control restrictions and sanctions imposed on certain businesses and individuals in Russia. We continue to monitor and evaluate additional sanctions and export restrictions that may be imposed by the U.S. Government or other governments, as well as any responses from Russia that could affect our supply chain, business partners or customers, for any additional impacts to our business.

Supply Chain We and our suppliers are experiencing supply chain disruptions as a result of 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. These factors have reduced overall productivity and adversely impacted our financial position, results of operations and cash flows.

The current conflict in Israel and the Gaza Strip has the potential to impact certain of our suppliers, and has impacted some operations for our airline and lessor customers. We are closely monitoring developments, supporting our employees and customers, and will take mitigating actions as appropriate.
