Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation 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 March 31, 2026, 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 2025 Annual Report on Form 10-K.
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
Our Military Aircraft reporting unit within our Defense, Space & Security (BDS) segment had goodwill of $1,295 and a negative carrying value at March 31, 2026.
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 Earnings from operations from changes in estimated losses on unexercised options.

Spirit Acquisition Spirit Acquisition
On December 8, 2025, we completed our acquisition of Spirit AeroSystems Holdings, Inc. (Spirit) pursuant to the Agreement and Plan of Merger dated June 30, 2024 (Merger Agreement). In connection with the closing of the transactions contemplated by the Merger Agreement (Spirit Acquisition), Boeing became the ultimate parent company of Spirit and its respective subsidiaries, including Spirit AeroSystems, Inc.
Total consideration for the Spirit Acquisition was $8,389 comprised of the following:
Boeing common stock exchanged for Spirit common stock (1)
$4,704 
Settlement of loans, advances and other payments to Spirit
2,589 
Debt repaid on Spirit’s behalf948

The amounts recorded for acquired assets and assumed liabilities are preliminary and are based on the information available as of the reporting date. The primary areas that remain preliminary relate to the fair values of inventories, property, plant and equipment, goodwill, intangible assets, and off-market contracts. The Company will continue to adjust the provisional estimates as additional information becomes available and final valuation and analyses are completed. Provisional goodwill of $10,360 associated with the Spirit Acquisition was provisionally assigned to our Commercial Airplanes (BCA) segment as we expect the majority of synergies from the Spirit Acquisition to relate to the commercial airplane segment. The acquired intangible assets primarily relate to customer relationships and have a weighted-average useful life of five years. Accrued liabilities includes $1,500 for the fair value of off-market customer
contracts measured as the present value of the amount by which the terms of the contract deviated from the terms that a market participant could have achieved. Future estimated revenues from the amortization of off-market contract liabilities is as follows:

Earnings Per Share

Mar. 31, 2026
Earnings Per Share [Abstract]  
Earnings Per Share 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.
Basic earnings per share is calculated by taking net earnings attributable to Boeing shareholders, less Mandatory convertible preferred stock dividends accumulated during the period and 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 Mandatory convertible preferred stock dividends accumulated during the period and 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 for share-based compensation awards and the if-converted method for Mandatory convertible preferred stock and Spirit Exchangeable Notes. Under the if-converted method, if the potential conversion of our Mandatory convertible preferred stock and/or Spirit Exchangeable Notes is dilutive, net earnings attributable to Boeing shareholders is adjusted to add back the Mandatory convertible preferred stock dividends accumulated during the period and/or the periodic interest expense on the Spirit Exchangeable Notes, net of tax.
The elements used in the computation of Basic and Diluted loss per share were as follows:

The following table represents potential common shares that were not included in the computation of Diluted loss per share. Potential common shares from performance restricted stock units, restricted stock units and stock options were not included because their effect was antidilutive based on their strike price or the performance condition was not met.

In addition, potential common shares of 37.0 million and 37.1 million for the three months ended March 31, 2026 and 2025, were excluded from the computation of Diluted loss per share, because the effect would have been antidilutive as a result of incurring a net loss available to common shareholders in those periods.

Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
Our effective tax rates were 126.9% and 140.8% for the three months ended March 31, 2026 and 2025. The effective tax rate for the three months ended March 31, 2026, primarily reflects an increase in the domestic valuation allowance treated as a discrete expense.
As of December 31, 2025, we had recorded valuation allowances of $9,754 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. 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.
Federal income tax audits have been settled for all years prior to 2021. We expect the next cycle to cover the 2021-2023 tax years; however, the Internal Revenue Service has not confirmed a start date. We are also subject to examination in major state and international jurisdictions for the 2010-2024 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.

Contributions to investments and Proceeds from investments on our Condensed Consolidated Statements of Cash Flows primarily relate to time deposits and available-for-sale debt investments. Cash used for the purchase of time deposits during the three months ended March 31, 2026 and 2025, was $9,085 and $8,635. Cash proceeds from the maturities of time deposits during the three months ended March 31, 2026 and 2025, were $16,100 and $7,585.
Allowance for losses on available-for-sale debt investments is assessed quarterly. These instruments are considered investment grade, and we have not recognized an allowance for credit losses as of March 31, 2026. The fair value of available-for-sale debt investments approximates amortized cost.
We have a 50 percent membership interest in United Launch Alliance (ULA) with Lockheed Martin Corporation (Lockheed) holding the other 50 percent interest. During the first quarter of 2026, ULA’s Vulcan rocket experienced a launch anomaly that has paused additional Vulcan launches pending completion of root cause analysis and corrective actions. The Vulcan launch suspension is negatively affecting ULA's financial condition and results of operations. We and Lockheed may provide financial support and/or could incur losses if ULA is unable to resume Vulcan launches consistent with ULA’s assumptions

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 March 31, 2026, and December 31, 2025, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $1,171 and $1,171.

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 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 March 31, 2026, have expiration dates from 2026 through 2033. At March 31, 2026, and December 31, 2025, total contractual trade-in commitments were $1,228 and $1,267. As of March 31, 2026, and December 31, 2025, we estimated it was probable we would be obligated to perform on certain of these commitments with net amounts payable to customers totaling $61 and $67 and the fair value of the related trade-in aircraft was $56 and $61.
Financing Commitments
Financing commitments related to aircraft on order, including options and those proposed in sales campaigns, and refinancing of delivered aircraft, totaled $17,730 and $15,229 as of March 31, 2026 and December 31, 2025. The estimated earliest potential funding dates for these commitments as of March 31, 2026 are as follows:

Total
April through December 2026

20283,538

Thereafter5,988 
Total
$17,730 
As of March 31, 2026, $12,590 of these financing commitments relate to customers we believe have less than investment-grade credit. We have concluded that no reserve for future potential losses is required for these financing commitments based upon the terms, such as collateralization and interest rates, under which funding would be provided.
Other Financial Commitments
We have financial commitments to make additional capital contributions totaling $281 to certain joint ventures over the next 12 years.
Standby Letters of Credit and Surety Bonds
We have entered into standby letters of credit and surety bonds with financial institutions primarily relating to the guarantee of our future performance on certain contracts and security agreements. Contingent liabilities on outstanding letters of credit agreements and surety bonds aggregated approximately $3,340 and $3,295 as of March 31, 2026 and December 31, 2025.
Supply Chain Financing Programs
The Company has supply chain financing programs in place under which participating suppliers may elect to obtain payment from an intermediary. The Company confirms the validity of invoices from participating suppliers and agrees to pay the intermediary an amount based on invoice totals. The majority of amounts payable under these programs are due within 30 to 90 days. At March 31, 2026, and December 31, 2025,
Accounts payable included $1,828 and $1,994 payable to suppliers who have elected to participate in these programs. We do not believe that future changes in the availability of supply chain financing would have a significant impact on our liquidity.
Recoverable Costs on Government Contracts
Our final incurred costs for each year are subject to audit and review for allowability by the U.S. government, which can result in payment demands related to costs they believe should be disallowed. We work with the U.S. government to assess the merits of claims and where appropriate reserve for amounts disputed. If we are unable to satisfactorily resolve disputed costs, we could be required to record an earnings charge and/or provide refunds to the U.S. government.
Fixed-Price Contracts
Long-term contracts that are contracted on a fixed-price basis or have fixed-price options have resulted in losses being recorded in prior periods and could result in losses in future periods. Certain of the fixed-price contracts are for the development of new products, services and related technologies, a number of which have reach-forward losses. Estimating the cost and time for us and our suppliers to complete these contracts is inherently uncertain due to operational and technical complexities. This uncertainty requires us to make significant judgments and assumptions about future operational and technical performance, and the outcome of customer and/or supplier contractual negotiations. The risk that actual performance, technical or contractual outcomes could be different than those previously assumed creates financial risk that could trigger additional material earnings charges, termination provisions, order cancellations, or other financially significant exposure.
VC-25B Presidential Aircraft
The Company’s firm fixed-price contract for the Engineering and Manufacturing Development (EMD) effort on the U.S. Air Force's (USAF) VC-25B Presidential Aircraft, commonly known as Air Force One, is a $4 billion program to develop and modify two 747-8 commercial aircraft. During 2025, we increased the reach-forward loss on the contract by $60. The increased reach-forward loss in 2025 was due to increases in supplier costs. We expect finalization of the contract terms to reset the schedule and adjust the requirements in 2026. Risk remains that we may record additional losses in future periods.
KC-46A Tanker
In 2011, we were awarded a contract from the USAF to design, develop, manufacture, and deliver four next-generation aerial refueling tankers as well as priced options for 13 annual production lots totaling 179 aircraft. Since 2016, the USAF has authorized 12 low rate initial production (LRIP) lots for a total of 169 aircraft. The EMD contract and authorized LRIP lots total approximately $32 billion as of March 31, 2026. The KC-46A Tanker is a derivative of the 767 commercial airplane program with the majority of the manufacturing costs being incurred in the 767 factory and the remaining costs being incurred in the military finishing and delivery centers. During 2025, we increased the reach-forward loss on the KC-46A Tanker program by $714. The additional reach-forward loss during 2025 was primarily driven by higher estimated manufacturing and engineering costs for production support. As of March 31, 2026, we had approximately $69 of capitalized precontract costs and $74 of potential termination liabilities to suppliers related to future production lots. Risk remains that we may record additional losses in future periods.
MQ-25
In the third quarter of 2018, we were awarded the MQ-25 EMD contract by the U.S. Navy. The contract is a fixed-price contract that now includes development and delivery of seven aircraft and test articles at a contract price of $890. In connection with winning the competition, we recognized a reach-forward loss of $291 in the third quarter of 2018. We have recognized additional losses in subsequent periods. During the first half of 2025, we initiated final assembly operations at our new facility at Mid-America St. Louis Airport in Mascoutah, Illinois, and began ground-based flight testing. Risk remains that we may record additional losses in future periods.
T-7A Red Hawk EMD Contract & Production Options
In 2018, we were awarded the T-7A Red Hawk program. The EMD portion of the contract was a $860 fixed-price contract and included five aircraft and seven simulators. In June 2025, the customer ordered four production representative test vehicles. The production portion of the contract includes production lots for 342 T-7A Red Hawk aircraft and related services that we believe are probable of being exercised. We recorded a reach-forward loss of $400 when the contract was awarded in 2018. We have recognized additional losses in subsequent periods. We have delivered the five EMD aircraft and the flight testing is ongoing. At March 31, 2026, we had approximately $400 of capitalized precontract costs and $1,002 of potential termination liabilities to suppliers related to certain long-lead items for future production lots. Risk remains that we may record additional losses in future periods.
Commercial Crew
In 2014, the National Aeronautics and Space Administration contracted us to design and build the CST-100 Starliner spacecraft to transport crews to the International Space Station (ISS). We have recorded reach-forward losses on this program. The first Crewed Flight Test launched on June 5, 2024, and docked with the ISS. Its return to Earth was delayed to allow time to perform further testing of propulsion system anomalies and returned to Earth uncrewed in September 2024. We expect to launch an uncrewed mission no earlier than June 2026 and a crewed mission later in 2026. We are continuing to work toward crew certification and resolve the propulsion system anomalies. At March 31, 2026, we had approximately $554 of capitalized precontract costs and $28 of potential termination liabilities to suppliers related to unauthorized future missions. Risk remains that we may record additional losses in future periods.

Contingent Repurchase Commitments In conjunction with signing a definitive agreement for the sale of commercial aircraft, we have entered into contingent repurchase commitments with certain customers wherein we agree to repurchase the sold aircraft at a specified price, generally 10 to 15 years after delivery. Our repurchase of the aircraft is contingent upon entering into a mutually acceptable agreement for the sale of additional new aircraft in the future. The commercial aircraft repurchase price specified in contingent repurchase commitments is generally lower than the expected fair value at the specified repurchase date. Estimated proceeds from collateral/recourse in the table above represent the lower of the contracted repurchase price or the expected fair value of each aircraft at the specified repurchase date.
If a future sale agreement is reached and a customer elects to exercise its right under a contingent repurchase commitment, the contingent repurchase commitment becomes a trade-in commitment. Our historical experience is that contingent repurchase commitments infrequently become trade-in commitments.
Credit Guarantees We have issued credit guarantees where we are obligated to make payments to a guaranteed party in the event that the original lessee or debtor does not make payments or perform certain specified services. Generally, these guarantees have been extended on behalf of guaranteed parties with less than investment-grade credit. Current outstanding credit guarantees expire through 2036.
Other Indemnifications In conjunction with our sales of Electron Dynamic Devices, Inc. and Rocketdyne Propulsion and Power businesses, we agreed to indemnify, for an indefinite period, the buyers for costs relating to pre-closing environmental conditions and certain other items. We are unable to assess the potential number of future claims that may be asserted under these indemnifications, nor the amounts thereof (if any). As a result, we cannot estimate the maximum potential amount of future payments under these indemnities. To the extent that claims have been made under these indemnities and/or are probable and reasonably estimable, liabilities associated with these indemnities are included in the environmental liability disclosure in Note 10.

On October 31, 2024, we issued 115,000,000 depositary shares, representing 5,750,000 shares of our 6.00% Series A Mandatory Convertible Preferred Stock (Mandatory convertible preferred stock). The Mandatory convertible preferred stock has a $1,000.00 per share liquidation preference and $1.00 per share par value. As a result of the transaction, we received cash proceeds of $5,651, net of underwriting fees and other issuance costs.
Dividends are cumulative at an annual rate of 6.00% on the liquidation preference of $1,000.00 per share of Mandatory convertible preferred stock and may be paid in cash, shares of our common stock or a combination of cash and shares of our common stock. Dividends that are declared will be payable on January 15, April 15, July 15 and October 15 to holders of record on the January 1, April 1, July 1, and October 1 immediately preceding the relevant dividend payment date. Dividends paid on Mandatory convertible preferred stock were $86 and $72 for the three months ended March 31, 2026 and 2025. In February 2026, dividends of $86 were declared to holders of record as of April 1, 2026, representing $15.00 per share, and were paid in cash on April 15, 2026.
The following table illustrates the conversion rate per share of Mandatory convertible preferred stock, subject to certain anti-dilution adjustments, based on the applicable market value of the common stock:

Based on our portfolio of cash flow hedges, we expect to reclassify gains of $8 (pre-tax) out of AOCI into earnings during the next 12 months.
We have derivative instruments with credit-risk-related contingent features. If we default on our five-year credit facilities, our derivative counterparties could require settlement for foreign exchange and certain commodity contracts with original maturities of at least five years. The fair value of those contracts in a net
liability position at March 31, 2026 was $4. For other particular commodity contracts, our counterparties could require collateral posted in an amount determined by our credit ratings. At March 31, 2026, there was no collateral posted related to our derivatives.

Fair Value Measurements Fair Value Measurements
The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant unobservable inputs. The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

Money market funds, available-for-sale debt investments and equity securities are valued using a market approach based on the quoted market prices or broker/dealer quotes of identical or comparable instruments.
Derivatives include foreign currency and commodity contracts. Our foreign currency forward contracts are valued using an income approach based on the present value of the forward rate less the contract rate multiplied by the notional amount. Commodity derivatives are valued using an income approach based on the present value of the commodity index prices less the contract rate multiplied by the notional amount.
Certain assets have been measured at fair value on a nonrecurring basis. The following table presents the nonrecurring losses recognized for the three months ended March 31 due to long-lived asset impairment and the fair value of the related assets as of the impairment date:

Total$22 ($9)$5 ($7)
Level 3 Investments and Other assets were primarily valued using an income approach based on the discounted cash flows associated with the underlying assets. These approaches are considered estimates of net operating income, capitalization rates, and/or comparable property sales. Level 3
operating lease equipment was valued by calculating a median collateral value from a consistent group of third-party aircraft value publications. The values provided by the third-party aircraft publications are derived from their knowledge of market trades and other market factors. Management reviews the publications quarterly to assess the continued appropriateness and consistency with market trends. Under certain circumstances, we adjust values based on the attributes and condition of the specific aircraft or equipment, usually when the features or use of the aircraft vary significantly from the more generic aircraft attributes covered by third-party publications, or on the expected net sales price for the aircraft.
For Level 3 operating lease equipment that were measured at fair value on a nonrecurring basis during the period ended March 31, 2026, the following table presents the fair value of those assets as of the measurement date, valuation techniques and related unobservable inputs of those assets.

The fair value of Notes receivable classified as Level 2 is estimated with discounted cash flow analysis using interest rates currently offered on loans with similar terms to borrowers of similar credit quality. The fair value of Notes receivable classified as Level 3 is based on our best estimate using available counterparty financial data. The fair value of our debt that is traded in the secondary market is classified as Level 2 and is based on current market yields. For our debt that is not traded in the secondary market, the fair value is classified as Level 2 and is based on our indicative borrowing cost derived from dealer quotes or discounted cash flows. With regard to other financial instruments with off-balance sheet risk, it is not practicable to estimate the fair value of our indemnifications and financing commitments because the amount and timing of those arrangements are uncertain. Items not included in the above disclosures include cash, restricted cash, time deposits and other deposits, Accounts receivable, Unbilled receivables, Other current assets, Accounts payable and long-term payables. The carrying values of those items, as
reflected in the Condensed Consolidated Statements of Financial Position, approximate their fair value at March 31, 2026 and December 31, 2025. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash (Level 1).

Legal Proceedings [Abstract]  
Legal Proceedings Legal Proceedings
We are subject, from time to time, to various legal proceedings and claims related to our business that cover a wide range of matters, including those related to products, contracts, labor and employment, securities, antitrust and trade regulations, intellectual property, and other matters. In addition, we are subject to various government inquiries and investigations from which civil, criminal or administrative proceedings could result or have resulted in the past. Such proceedings involve or could involve claims by the U.S. or foreign governments for fines, penalties, compensatory and treble damages, restitution and/or forfeitures. Under U.S. government regulations, a company, or one or more of its operating divisions or subdivisions, can be suspended or debarred from government contracts, have certain of its production certificates suspended or revoked, or lose its export privileges, based on the results of investigations.
On May 29, 2025, Boeing and the U.S. Department of Justice (the Department) entered into a non-prosecution agreement (the Agreement) to resolve the Department’s determination that Boeing did not fulfill its obligations under the January 2021 deferred prosecution agreement relating to the October 2018 Lion Air flight 610 accident and the March 2019 Ethiopian Airlines flight 302 accident (the MAX accidents). The Agreement requires, among other things, Boeing to pay a fine of $244 and provide $445 of additional compensation for the family members of those who died in the MAX accidents. The $244 fine, which was accrued for and expensed in 2024, and the $445 compensation fund for family members, which was accrued for and expensed in the second quarter of 2025, are held in escrow accounts pending final court approval of the Department’s motion to dismiss the criminal information against Boeing (the Motion). On November 6, 2025, the U.S. District Court for the Northern District of Texas (the Court) approved the Motion. On March 31, 2026, the U.S. Court of Appeals for the Fifth Circuit denied a petition by representatives of certain family members to overturn the Court's approval of the Motion. Those representatives have filed a further appeal.
Certain legal actions and investigations arising out of the MAX accidents and subsequent grounding of the 737 MAX are still pending, including fewer than five civil lawsuits by family members of those who died in the MAX accidents. In addition, securities lawsuits are pending, and we are appealing the March 16, 2026, partial grant of a motion for class certification by the U.S. District Court for the Northern District of Illinois. Multiple investigations and legal actions, including securities lawsuits, were also initiated as a result of the January 2024 737-9 door plug accident.
Given the status of these legal actions and investigations, we cannot reasonably estimate a range of loss, if any, not covered by available insurance and in excess of any accrued amounts, that may result from these matters.

Segment Reporting [Abstract]  
Segment and Revenue Information Segment and Revenue Information
We operate in three reportable segments: BCA, BDS, and BGS. All other activities fall within Unallocated items, eliminations and other. See page 6 for the Summary of Business Segment Data, which is an integral part of this note.
BCA develops, produces and markets commercial jet aircraft principally to the commercial airline industry worldwide. Revenue on commercial aircraft contracts is recognized at the point in time when an aircraft is completed and accepted by the customer.
BDS engages in the research, development, production and modification of the following products and related services: manned and unmanned military aircraft and weapons systems, surveillance and engagement, strategic defense and intelligence systems, satellite systems and space exploration. BDS revenue is generally recognized over the contract term (over time) as costs are incurred.
BGS provides parts, maintenance, modifications, logistics support, training, data analytics and information-based services to commercial and government customers worldwide. BGS segment revenue and costs include certain products and services provided to other segments. Revenue on commercial spare parts contracts is recognized at the point in time when a spare part is delivered to the customer. Revenue on other contracts is generally recognized over the contract term (over time) as costs are incurred.
The primary profitability measurement used by our chief operating decision maker to review segment operating results is Segment operating earnings. The following table reconciles segment Revenues to Segment operating earnings:

The following tables present BCA, BDS and BGS revenues from contracts with customers disaggregated in a number of ways, such as geographic location, contract type and the method of revenue recognition. We believe these best depict how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors.

Earnings in Equity Method Investments
During the three months ended March 31, 2026, our share of income/(loss) from equity method investments was $0 compared to ($4) during the same period in 2025.
Backlog
Our total backlog includes contracts that we and our customers are committed to perform. The value in backlog represents the estimated transaction prices on performance obligations to our customers for which work remains to be performed. Backlog is converted into revenue, primarily based on the cost incurred or at delivery and acceptance of products, depending on the applicable revenue recognition model.
Our backlog at March 31, 2026 was $694,709. We expect approximately 24% to be converted to revenue through 2027 and approximately 65% through 2030, with the remainder thereafter. There is significant uncertainty regarding the timing of when backlog will convert into revenue. We may experience reductions to backlog and/or significant order cancellations due to various factors including delivery delays, production disruptions and delays to entry into service of the 777X, 737-7 and/or 737-10.
Unallocated Items, Eliminations and Other
Unallocated items, eliminations and other include common internal services that support Boeing’s global business operations and eliminations of certain sales between segments. We generally allocate costs to business segments based on the U.S. Government Cost Accounting Standards (CAS). Components of Unallocated items, eliminations and other income/(expense) are shown in the following table.

Pension and Other Postretirement Benefit Expense
Pension costs are allocated to BDS and BGS businesses supporting government customers using CAS, which employ different actuarial assumptions and accounting conventions than GAAP. These costs are allocable to government contracts. Other postretirement benefit costs are allocated to business segments based on CAS, which is generally based on benefits paid. FAS/CAS service cost adjustment represents the difference between the Financial Accounting Standards (FAS) pension and postretirement service costs calculated under GAAP and costs allocated to the business segments. Non-operating pension and postretirement expenses represent the components of net periodic benefit costs other than service cost. These expenses are included in Other income, net. Components of FAS/CAS service cost adjustment are shown in the following table:

Use of Estimates
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.
Long-term Contracts
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.
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.
Basic earnings per share is calculated by taking net earnings attributable to Boeing shareholders, less Mandatory convertible preferred stock dividends accumulated during the period and 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 Mandatory convertible preferred stock dividends accumulated during the period and 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 for share-based compensation awards and the if-converted method for Mandatory convertible preferred stock and Spirit Exchangeable Notes. Under the if-converted method, if the potential conversion of our Mandatory convertible preferred stock and/or Spirit Exchangeable Notes is dilutive, net earnings attributable to Boeing shareholders is adjusted to add back the Mandatory convertible preferred stock dividends accumulated during the period and/or the periodic interest expense on the Spirit Exchangeable Notes, net of tax.
Backlog
Backlog
Our total backlog includes contracts that we and our customers are committed to perform. The value in backlog represents the estimated transaction prices on performance obligations to our customers for which work remains to be performed. Backlog is converted into revenue, primarily based on the cost incurred or at delivery and acceptance of products, depending on the applicable revenue recognition model.
