Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
Principles of Consolidation and Basis of Presentation
The Consolidated 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”). These statements include the accounts of all majority-owned subsidiaries and variable interest entities that are required to be consolidated. All significant intercompany accounts and transactions have been eliminated. As described in Note 24, we operate in three reportable segments: Commercial Airplanes (BCA), Defense, Space & Security (BDS), and Global Services (BGS).
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.
Operating Cycle
For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year.
Revenue and Related Cost Recognition
Commercial aircraft contracts The majority of our BCA segment revenue is derived from commercial aircraft contracts. For each contract, we determine the transaction price based on the consideration expected to be received. We allocate the transaction price to each commercial aircraft performance obligation based on relative standalone selling prices adjusted by an escalation formula as specified in the customer agreement. Revenue is recognized for each commercial aircraft performance obligation at the point in time when the aircraft is completed and accepted by the customer. We use program accounting to determine the amount reported as cost of sales.
Payments for commercial aircraft sales are received in accordance with the customer agreement, which generally includes a deposit upon order and additional payments in accordance with a payment schedule, with the balance being due immediately prior to or at aircraft delivery. Advances and progress billings (contract liabilities) are normal and customary for commercial aircraft contracts and not considered a significant financing component as they are intended to protect us from the other party failing to adequately complete some or all of its obligations under the contract.
Long-term contracts Substantially all contracts at BDS and certain contracts at BGS are long-term contracts with the U.S. government and other customers that generally extend over several years. Products sales under long-term contracts primarily include fighter jets, rotorcraft, cybersecurity products, surveillance suites, advanced weapons, missile defense, military derivative aircraft, satellite systems and modification of commercial passenger aircraft to cargo freighters. Sales of services under long-term contracts primarily include support and maintenance agreements associated with our commercial and defense products and space travel on Commercial Crew.
For each long-term contract, we determine the transaction price based on the consideration expected to be received. We allocate the transaction price to each distinct performance obligation to deliver a good or service, or a collection of goods and/or services, based on the relative standalone selling prices. A long-term contract will typically represent a single distinct performance obligation due to the highly interdependent and interrelated nature of the underlying goods and/or services and the significant service of integration that we provide. While the scope and price on certain long-term contracts may be modified over their life, the transaction price is based on current rights and obligations under the contract and does not include potential modifications until they are agreed upon with the customer. When applicable, a cumulative adjustment or separate recognition for the additional scope and price may result. Long-term contracts can be negotiated with a fixed price or a price in which we are reimbursed for costs incurred plus an agreed upon profit. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing the price for contracts with the U.S. government. Certain long-term contracts include in the transaction price variable consideration, such as incentive and award fees, if specified targets are achieved. The amount included in the transaction price represents the expected value, based on a weighted probability, or the most likely amount.
Long-term contract revenue is recognized over the contract term (over time) as the work progresses, either as products are produced or as services are rendered. We generally recognize revenue over time as we perform on long-term contracts because of continuous transfer of control to the customer. For U.S. government contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. Similarly, for non-U.S. government contracts, the customer typically controls the work in process as evidenced either by contractual termination clauses or by our rights to payment of the transaction price associated with work performed to date on products or services that do not have an alternative use to the Company.
The accounting for long-term contracts involves a judgmental process of estimating total revenues, costs and profit for each performance obligation. Cost of sales is recognized as incurred. The amount reported as revenues is determined by adding a proportionate amount of the estimated profit to the amount reported as cost of sales. Recognizing revenue as costs are incurred provides an objective measure of progress on the long-term contract and thereby best depicts the extent of transfer of control to the customer.
For long-term contracts for which revenue is recognized over time, 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/(loss) from operations from changes in estimated losses on unexercised options for the years ended December 31:

Significant adjustments during the three years ended December 31, 2025, 2024 and 2023, included losses on KC-46A Tanker, VC-25B, T-7A Red Hawk, MQ-25, and Commercial Crew programs.
Due to the significance of judgment in the estimation process, changes in underlying operational assumptions, inability to implement planned risk mitigation plans, failure to achieve productivity targets, supplier shortages, quality issues and/or pricing issues, inflationary trends, or other circumstances may adversely or positively affect financial performance in future periods.
Payments under long-term contracts may be received before or after revenue is recognized. The U.S. government customer typically withholds payment of a small portion of the contract price until contract completion. Therefore, long-term contracts typically generate Unbilled receivables (contract assets) but may generate Advances and progress billings (contract liabilities). Long-term contract Unbilled receivables and Advances and progress billings are not considered a significant financing component because they are intended to protect either the customer or the Company in the event that some or all of the obligations under the contract are not completed.
Commercial spare parts contracts Certain contracts at our BGS segment include sales of commercial spare parts. For each contract, we determine the transaction price based on the consideration expected to be received. The spare parts have discrete unit prices that represent fair value. We generally consider each spare part to be a separate performance obligation. Revenue is recognized for each commercial spare part performance obligation at the point in time of delivery to the customer. We may provide our customers with a right to return a commercial spare part where a customer may receive a full or partial refund, a credit applied to amounts owed, a different product in exchange, or any combination of these items. We consider the potential for customer returns in the estimated transaction price. The amount reported as cost of sales is recorded at average cost. Payments for commercial spare parts sales are typically received shortly after delivery.
Other service revenue contracts Certain contracts at our BGS segment are for sales of services to commercial customers including maintenance, training, and digital solutions and analytics. We recognize revenue for these service performance obligations over time as the services are rendered. The method of measuring progress (such as straight-line or billable amount) varies depending upon which method best depicts the transfer of control to the customer based on the type of service performed. Cost of sales is recorded as incurred.
Concession sharing arrangements We account for sales concessions to our customers in consideration of their purchase of products and services as a reduction of the transaction price and the revenue that is recognized for the related performance obligations. The sales concessions incurred may be partially reimbursed by certain suppliers in accordance with concession sharing arrangements. We record these reimbursements, which are presumed to represent reductions in the price of the vendor’s products or services, as a reduction in Cost of products.
Unbilled receivables and advances and progress billings Unbilled receivables (contract assets) arise when the Company recognizes revenue for amounts which cannot yet be billed under terms of the contract with the customer. Advances and progress billings (contract liabilities) arise when the Company receives payments from customers in advance of recognizing revenue. The amount of Unbilled receivables or Advances and progress billings is determined for each contract.
Financial services revenue We record financial services revenue associated with sales-type leases, operating leases and loans in Sales of services on the Consolidated Statements of Operations. For sales-type leases, we recognize selling profit or loss at lease inception if collection of the lease payments is probable. For sales-type leases, we record financing receivables at lease inception. A financing receivable is recorded at the aggregate of future lease payments, estimated residual value of the leased equipment, and any deferred incremental direct costs less unearned income. Income is recognized over the life of the lease to approximate a level rate of return on the net investment. For notes receivable, we record financing receivables net of any unamortized discounts and deferred
incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note.
Income recognition is generally suspended for financing receivables that are uncollectible. We determine that a financing receivable is uncollectible when, based on current information and events, it is probable that we will be unable to collect amounts due according to the original contractual terms. We determine a financing receivable is past due when cash has not been received upon the due date specified in the contract.
We evaluate the collectability of financing receivables at commencement and on a recurring basis. If a financing receivable is determined to be uncollectible, the customer is categorized as non-accrual status. When a customer is in non-accrual status at commencement, sales-type lease revenue is deferred until substantially all cash has been received or the customer is removed from non-accrual status. If we have a note receivable with a customer that is in non-accrual status, or a sales-type lease with a customer that changes to non-accrual status after commencement, we recognize contractual interest income as payments are received to the extent there is sufficient collateral and payments exceed past due principal payments.
Residual values, which are reviewed periodically, represent the estimated amount we expect to receive at lease termination from the disposition of the leased equipment. Actual residual values realized could differ from these estimates. Declines in estimated residual value that are deemed other-than-temporary are recognized in the period in which the declines occur.
For operating leases, revenue on leased aircraft and equipment is recorded on a straight-line basis over the term of the lease. Operating lease assets, included in Financing receivables and operating lease equipment, net, are recorded at cost and depreciated to an estimated residual value using the straight-line method over the period that we project we will hold the asset. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense. We record assets held for sale at the lower of carrying value or fair value less costs to sell. We evaluate for impairment assets under operating leases when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.
Reinsurance Our wholly-owned insurance subsidiary, Astro Ltd., participates in a reinsurance pool for workers’ compensation. The member agreements and practices of the reinsurance pool minimize any participating members’ individual risk. Reinsurance revenues were $99, $110 and $163 during 2025, 2024 and 2023, respectively. Reinsurance costs related to premiums and claims paid to the reinsurance pool were $123, $123 and $181 during 2025, 2024 and 2023, respectively. Revenues and costs are presented net in Cost of products and Cost of services in the Consolidated Statements of Operations.
Research and Development
Research and development includes costs incurred for experimentation, design and testing, as well as bid and proposal efforts related to government products and services, which are expensed as incurred unless the costs are related to certain contractual arrangements with customers. Costs that are incurred pursuant to such contractual arrangements are recorded over the period that revenue is recognized, consistent with our long-term contract accounting policy. We have certain research and development arrangements with customers that meet the conditions for best efforts research and development accounting. Accordingly, the amounts funded by the customer are recognized as an offset to our research and development expense rather than as contract revenues. Research and development expense, net included bid and proposal costs of $161, $179 and $188 in 2025, 2024 and 2023, respectively.
Share-Based Compensation
We provide various forms of share-based compensation to our employees. For awards settled in shares, we measure compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, or that may be settled in cash, we measure compensation expense based on the fair value at each reporting date net of estimated forfeitures. The expense is recognized over the requisite service period, which is generally the vesting period of the award.
Income Taxes
Provisions for U.S. federal, state and local, and non-U.S. income taxes are calculated on reported Earnings/(loss) before income taxes based on current tax law and also include, in the current period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions.
The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. We record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. Tax-related interest and penalties are classified as a component of Income tax (expense)/benefit.
We also assess the likelihood that we will be able to recover our deferred tax assets against future sources of taxable income and reduce the carrying amounts of deferred tax assets by recording a valuation allowance if, based on the available evidence, it is more likely than not that all or a portion of such assets will not be realized. Changes in our estimates and judgments regarding realization of deferred tax assets may result in an increase or decrease to our tax expense and/or other comprehensive income, which would be recorded in the period in which the change occurs.
Postretirement Plans
Many of our employees have earned benefits under defined benefit pension plans. The majority of employees that had participated in defined benefit pension plans have transitioned to a company-funded defined contribution retirement savings plan. We also provide postretirement benefit plans other than pensions, consisting principally of health care coverage to eligible retirees and qualifying dependents. Benefits under the pension and other postretirement benefit plans are generally based on age at retirement and years of service and, for some pension plans, benefits are also based on the employee’s annual earnings. The net periodic cost of our pension and other postretirement plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the long-term rate of asset return and medical trend (rate of growth for medical costs). Actuarial gains and losses, which occur when actual experience differs from actuarial assumptions, are reflected in Shareholders’ equity (net of taxes). If actuarial gains and losses exceed 10 percent of the greater of plan assets or plan liabilities, we amortize them over the average expected future lifetime of participants. The funded status of our pension and postretirement plans is reflected on the Consolidated Statements of Financial Position.
Postemployment Plans
We record a liability for postemployment benefits, such as severance or job training, when payment is probable and the amount is reasonably estimable.
Environmental Remediation
We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.
Cash and Cash Equivalents
Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits and other money market instruments, which have original maturities of three months or less. We aggregate our cash balances by bank where conditions for right of set-off are met, and reclassify any negative balances, consisting mainly of uncleared checks, to Accounts payable. Negative balances reclassified to Accounts payable were $127 and $110 at December 31, 2025 and 2024.
Inventories
Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring costs, and applicable overhead, which includes fringe benefits, production related indirect and plant management salaries and plant services, not in excess of estimated net realizable value. To the extent a material amount of such costs are related to an abnormal event or are fixed costs not appropriately attributable to our programs or contracts, they are expensed in the current period rather than inventoried. Inventoried costs include amounts relating to programs and contracts with long-term production cycles, a portion of which is not expected to be realized within one year. Included in inventory for federal government contracts is an allocation of allowable costs related to manufacturing process reengineering.
Commercial aircraft programs inventory includes deferred production costs and supplier advances. Deferred production costs represent actual costs incurred for production of early units that exceed the estimated average cost of all units in the program accounting quantity. Higher production costs are experienced at the beginning of a new or derivative aircraft program. Units produced early in a program require substantially more effort (labor and other resources) than units produced later in a program because of volume efficiencies and the effects of learning. We expect that these deferred costs will be fully recovered when all units included in the accounting quantity are delivered as the expected unit cost for later deliveries is below the estimated average cost of all units in the program. Supplier advances represent payments for parts we have contracted to receive from suppliers in the future. As parts are received, supplier advances are amortized to work in process.
The determination of net realizable value of long-term contract costs is based upon quarterly reviews that estimate costs to be incurred to complete all contract requirements. When actual contract costs and the estimate to complete exceed total estimated contract revenues, a loss provision is recorded. The determination of net realizable value of commercial aircraft program costs is based upon quarterly program reviews that estimate revenue and cost to be incurred to complete the program accounting quantity. When estimated costs to complete exceed estimated program revenues to go, a program loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.
Used aircraft purchased by our BCA segment and general stock materials are stated at cost not in excess of net realizable value. Spare parts inventory is stated at lower of average unit cost or net realizable value. We review our commercial spare parts and general stock materials quarterly to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends, expected production usage, and the size and age of the aircraft fleet using the part. Impaired inventories are charged to Cost of products in the period the impairment occurs.
Included in inventory for commercial aircraft programs are amounts paid or credited in cash, or other consideration to certain airline customers, that are referred to as early issue sales consideration. Early issue sales consideration is recognized as a reduction to revenue when the delivery of the aircraft under contract occurs. If an airline customer does not perform and take delivery of the contracted aircraft, we believe that we would have the ability to recover amounts paid. However, to the extent early issue sales consideration exceeds advances and is not considered to be otherwise recoverable, it would be written off against revenue of the current period.
Precontract Costs
We may, from time to time, incur costs in excess of the amounts required for existing contracts. If we determine the costs are probable of recovery from future orders, then we capitalize the precontract costs we incur, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories in the accompanying Consolidated Statements of Financial Position. Should future orders not materialize or we determine the costs are no longer probable of recovery, the capitalized costs would be written off.
Property, Plant and Equipment
Property, plant and equipment are recorded at cost, including applicable construction-period interest, less accumulated depreciation and are depreciated principally over the following estimated useful lives: new buildings and land improvements, from 10 to 40 years; and new machinery and equipment, from four to 20 years. The principal method of depreciation for buildings and land improvements is 150% declining balance and for machinery and equipment is sum-of-the-years’ digits. Capitalized internal use software is included in Other assets, net and amortized using the straight line method over five years. Capitalized costs of software purchased as a service are included in Other assets, net and amortized using the straight line method over the term of the hosting arrangement, which is typically no greater than 10 years. We periodically evaluate the appropriateness of remaining depreciable lives assigned to long-lived assets, including assets that may be subject to a management plan for disposition.
Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Long-lived assets held for use are subject to an impairment assessment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
Leases
We determine if an arrangement is, or contains, a lease under which we are the lessee at the inception date. Operating lease assets are included in Other assets, net, with the related liabilities included in Accrued liabilities and Other long-term liabilities. Assets under finance leases, which primarily represent computer equipment, are included in Property, plant and equipment, net, with the related liabilities included in Short-term debt and current portion of long-term debt and Long-term debt on the Consolidated Statements of Financial Position.
Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease
assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as fair market value adjustments, utilities and maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term.
We have real property lease agreements with lease and non-lease components which are accounted for as a single lease component.
Asset Retirement Obligations
We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning and contractual lease restoration obligations. Recorded amounts are not material.
We also have known conditional asset retirement obligations, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the Consolidated Financial Statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability’s fair value. In addition, there may be conditional asset retirement obligations that we have not yet discovered (e.g. asbestos may exist in certain buildings but we have not become aware of it through the normal course of business), and therefore, these obligations also have not been included in the Consolidated Financial Statements.
Goodwill and Other Acquired Intangibles
Goodwill and other acquired intangible assets with indefinite lives are not amortized, but are tested for impairment annually and when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Our annual testing date is April 1.
We test goodwill for impairment by performing a qualitative assessment or using a quantitative test. If we choose to perform a qualitative assessment and determine it is more likely than not that the carrying value of the net assets is more than the fair value of the related operations, the quantitative test is then performed; otherwise, no further testing is required. For operations where the quantitative test is used, we compare the carrying value of net assets to the estimated fair value of the related operations. If the fair value is determined to be less than carrying value, the shortfall up to the carrying value of the goodwill represents the amount of goodwill impairment.
We performed our annual goodwill impairment test as of April 1, 2025, using a qualitative assessment. We determined the fair value of each of our reporting units substantially exceeded their respective carrying values. Our Military Aircraft reporting unit within our BDS segment had goodwill of $1,295 and a negative carrying value at December 31, 2025.
Indefinite-lived intangibles consist of in-process research and development (IPR&D) acquired in a business combination. IPR&D is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. IPR&D is reclassified to finite-lived acquired intangible assets when a project is completed and then amortized on a straight-line basis over the asset’s estimated useful life. We test IPR&D for impairment by comparing the carrying value to current projections of related discounted cash flows. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment.
Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from three to 10 years; product know-how, from nine to 13 years; customer base, from seven to 17 years; distribution rights, from eight to 24 years; and other, from three to 32 years. We evaluate the potential impairment of finite-lived acquired intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
Investments
Time deposits are held-to-maturity investments that are carried at cost.
Available-for-sale debt investments include commercial paper, corporate notes and U.S. government agency securities. Available-for-sale debt investments are recorded at fair value, and unrealized gains and losses are recorded, net of tax, as a component of accumulated other comprehensive income. Realized gains and losses on available-for-sale debt investments are recognized based on the specific identification method. Available-for-sale debt investments are assessed for impairment quarterly.
The equity method of accounting is used to account for investments for which we have the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of an investee of between 20% and 50%. The cumulative earnings approach is used for cash flow classification of distributions received from equity method investments.
Other Equity investments are recorded at fair value, with gains and losses recorded through net earnings. Equity investments without readily determinable fair value are measured at cost, less impairments, plus or minus observable price changes. Equity investments without readily determinable fair value are assessed for impairment quarterly.
We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating in nature. Operating investments align strategically and are integrated with our operations. Earnings from operating investments, including our share of income or loss from equity method investments, dividend income from other equity investments, and any impairments or gain/loss on the disposition of these investments, are recorded in Income from operating investments, net. Non-operating investments are those we hold for non-strategic purposes. Earnings from non-operating investments, including interest and dividends on marketable securities, and any impairments or gain/loss on the disposition of these investments are recorded in Other income, net.
Derivatives
All derivative instruments are recognized in the financial statements and measured at fair value regardless of the purpose or intent of holding them. We principally use derivative instruments to manage a variety of market risks. For our cash flow hedges, the derivative’s gain or loss is initially reported in comprehensive income and is subsequently reclassified into earnings in the same period(s) during which the hedged forecasted transaction affects earnings.
We hold certain other derivative instruments for economic purposes. These derivative instruments are derivatives for accounting purposes but are not designated as hedges for accounting purposes. For derivative instruments not designated for hedge accounting treatment, the changes in their fair value are recorded in earnings immediately.
Allowances for Losses on Certain Financial Assets
We establish allowances for credit losses on accounts receivable, unbilled receivables, financing receivables and certain other financial assets. The adequacy of these allowances is assessed quarterly through consideration of factors such as customer credit ratings, bankruptcy filings, published or estimated credit default rates, age of the receivable, expected loss rates and collateral exposures. Collateral exposure is the excess of the carrying value of a financial asset over the fair value of the related collateral. We determine the creditworthiness of our customers by assigning internal credit ratings based upon publicly available information and information obtained directly from the customers. Our rating categories are comparable to those used by major credit rating agencies.
Financing receivables are collateralized by security in the related asset. We use a median calculated from published collateral values from multiple third-party aircraft value publications based on the type and age of the aircraft to determine the fair value of aircraft collateral. Under certain circumstances, we apply judgment based on the attributes 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 outside publications.
We have entered into agreements with certain customers and suppliers to whom we have provided financing that would entitle us to look beyond the specific collateral underlying the receivable for purposes of determining the collateral exposure. Should the proceeds from the sale of the underlying collateral asset resulting from a default condition be insufficient to cover the carrying value of our receivable (creating a shortfall condition), these agreements would, for example, permit us to take the actions necessary to sell or retain certain other assets in which the customer or supplier has an equity interest and use the proceeds to cover the shortfall.
Commercial Aircraft Trade-in Commitments
In conjunction with signing a definitive agreement for the sale of new commercial aircraft (Sale 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.
Exposure related to trade-in commitments may take the form of:
(1)adjustments to revenue for the difference between the contractual trade-in price in the definitive agreement and our best estimate of the fair value of the trade-in aircraft as of the date of such agreement, which would be recognized upon delivery of the Sale Aircraft, and/or
(2)charges to cost of products for adverse changes in the fair value of trade-in aircraft that occur subsequent to signing of a definitive agreement for Sale Aircraft but prior to the purchase of the used trade-in aircraft. Estimates based on current aircraft values would be included in Accrued liabilities.
The fair value of trade-in aircraft is determined using aircraft-specific data such as model, age and condition, market conditions for specific aircraft and similar models, and multiple valuation sources. This process uses our assessment of the market for each trade-in aircraft, which in most instances begins years before the return of the aircraft. There are several possible markets in which we continually pursue opportunities to place used aircraft. These markets include, but are not limited to, the resale market, which could potentially include the cost of long-term storage; the leasing market, with the potential for refurbishment costs to meet the leasing customer’s requirements; or the scrap market. Trade-in aircraft valuation varies significantly depending on which market we determine is most likely for each aircraft. On a quarterly basis, we update our valuation analysis based on the actual activities associated with placing each aircraft into a market or using current published third-party aircraft valuations based on the type and age of the aircraft, adjusted for individual attributes and known conditions.
Warranties
In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance to specifications and defects in material and design. The majority of our warranties are issued by our BCA segment. Generally, aircraft sales are accompanied by a three to four-year standard warranty for systems, accessories, equipment, parts, and software manufactured by us or manufactured to certain standards under our authorization. These warranties are included in the estimates to complete the related programs. On occasion we have made commitments beyond the standard warranty obligation to correct fleet-wide major issues of a particular model, resulting in additional accrued warranty expense. Warranties issued by our BDS segment principally relate to sales of military aircraft and weapons systems. These sales are generally accompanied by a six month to two-year warranty period and cover systems, accessories, equipment, parts and software manufactured by us to certain contractual specifications. Estimated costs related to standard warranties are recorded in the period in which the related product delivery occurs. The warranty liability recorded at each balance sheet date reflects the estimated number of months of warranty coverage outstanding for products delivered times the average of historical monthly warranty payments, as well as additional amounts for certain major warranty issues that exceed a normal claims level. Estimated costs of these additional warranty issues are considered changes to the initial liability estimate.
We provide guarantees to certain commercial aircraft customers which include compensation provisions for failure to meet specified aircraft performance targets. We account for these performance guarantees as warranties. The estimated liability for these warranties is based on known and anticipated operational characteristics and forecasted customer operation of the aircraft relative to contractually specified performance targets, and anticipated settlements when contractual remedies are not specified. Estimated payments are recorded as a reduction of revenue at delivery of the related aircraft. We have agreements that require certain suppliers to compensate us for amounts paid to customers for failure of supplied equipment to meet specified performance targets. Claims against suppliers under these agreements are included in Inventories and recorded as a reduction in Cost of products at delivery of the related aircraft. These performance warranties and claims against suppliers are included in estimates to complete the related programs.
Supplier Penalties
We may incur penalties to suppliers under certain circumstances such as a contract termination. We record an accrual for supplier penalties when an event occurs that makes it probable we will incur a supplier penalty and the amount is reasonably estimable.
Guarantees
At the inception of a guarantee, we record a liability in Accrued liabilities for the fair value of the guarantee. For credit guarantees, the liability is equal to the present value of the expected loss. We determine the expected loss by multiplying the creditor’s default rate by the guarantee amount reduced by the expected recovery, if applicable. We also recognize a liability for the expected contingent loss at inception and adjust it each quarter.

Spirit Acquisition
 12 Months Ended
Dec. 31, 2025
Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]  
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. (Spirit Sub). The Spirit Acquisition enables Boeing and Spirit to align our commercial production systems, including our Safety and Quality Management Systems, and our workforces to the
same priorities, incentives and outcomes.
Total consideration for the Spirit Acquisition was $8,371 comprised of the following:
Boeing common stock exchanged for Spirit common stock (1)
$4,704 
Settlement of loans, advances and other payments to Spirit
2,571 
Debt repaid on Spirit’s behalf948 
Premium on assumed Spirit Exchangeable Notes
109 
Exchange of Spirit share-based awards (1)
39 
Fair value of total consideration
$8,371 
(1)     Fair value of consideration reflects the price per share of Boeing common stock on the acquisition date.
In accordance with the Merger Agreement, 117.5 million shares of Spirit common stock were exchanged for 22.98 million shares of Boeing common stock at an exchange ratio of 0.1955. The exchange ratio was calculated as $37.25 divided by the $190.493 volume weighted average price per share of Boeing common stock on the New York Stock Exchange for the 15-trading-day period ended on December 4, 2025.
Since 2023, Boeing has provided funding in the form of loans and advance payments to Spirit to support its liquidity, rate readiness, and 787 tooling and capital expenditures. Pursuant to the terms of the Merger Agreement, Boeing also provided funding to Spirit for the portion of the payment to Airbus SE (Airbus) that Spirit was unable to satisfy with cash on hand as of the closing of the transactions contemplated by the Stock and Asset Purchase Agreement, dated April 27, 2025, between Spirit and Airbus, which closing occurred concurrently with the Spirit Acquisition. Such amounts totaling $2,571 were deemed to be consideration.
We expensed $53 of acquisition related costs in the Consolidated Statements of Operations as General and administrative expense during the year ended December 31, 2025. The results of Spirit’s operations between the acquisition date and December 31, 2025, were not material. We have determined disclosure of 2025 and 2024 proforma revenue and earnings of Boeing combined with the acquired Spirit business is impracticable. Historical financial results of the acquired portion of the Spirit business are not readily available. To prepare proforma revenue and earnings would require revising historical estimates used in our long-term contract and program accounting as if the Spirit Acquisition had occurred at January 1, 2024 which is impracticable.

Total net assets acquired$8,371 
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 $9,997 associated with the Spirit Acquisition was provisionally assigned to our 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 $1,065 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

Dec. 31, 2025
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 Exchangeable Notes. Under the if-converted method, if the potential conversion of our Mandatory convertible preferred stock and/or 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 Exchangeable Notes, net of tax.
The elements used in the computation of Basic and Diluted earnings/(loss) per share were as follows:

The following table represents potential common shares that were not included in the computation of Diluted earnings/(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. Potential common shares from Mandatory convertible preferred stock and Exchangeable Notes were not included because their effect was antidilutive based on the application of the if-converted method.

The German Digital Aviation Solutions Divestiture rate benefit was due to the statutory rate difference of ($203) (7.7)% and a participation exemption of ($548) (20.8)%. The Swedish rate benefit was entirely due to a participation exemption.
(3)    Related to the Digital Aviation Solutions Divestiture, in the U.S., we recorded a Global Intangible Low-Taxed Income inclusion, which is offset by a decrease in the federal valuation allowance, resulting in no federal tax expense.
(4)    The worldwide valuation allowance recorded in tax expense was $120 with $50 federal tax benefit shown on this line, $161 state tax expense included in State and Local Tax line item, and $9 foreign tax expense included in Foreign Tax Effects.

($109)$63 
The Company’s deferred income tax assets of $21,065 can be used in future years to offset taxable income and reduce income taxes payable. The Company’s deferred income tax liabilities of $11,420 will partially offset deferred income tax assets and result in higher taxable income in future years and increase income taxes payable. Tax law determines whether future reversals of temporary differences will result in taxable and deductible amounts that offset each other in future years. The particular years in which temporary differences result in taxable or deductible amounts generally are determined by the timing of the recovery of the related asset or settlement of the related liability. The deferred income tax assets and liabilities relate primarily to U.S. federal and state tax jurisdictions. From a U.S. federal tax perspective, the Company generated tax net operating losses in 2021, 2024 and 2025 and interest carryovers in 2021 through 2025 that can be carried forward indefinitely and federal research and development credits that can be carried forward 20 years.
Throughout 2024 and 2025, the Company was in a three-year cumulative pre-tax loss position. For purposes of assessing the recoverability of deferred tax assets, the Company determined that it could not include future projected earnings in the analysis due to recent history of losses.
As of December 31, 2025 and 2024, the Company has recorded valuation allowances of $9,754 and $7,837 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.
In 2025, the Company’s valuation allowance increased by $1,917, primarily reflecting $1,833 recorded as part of acquisition accounting against acquired Spirit deferred tax assets, as well as tax credits and other carryforwards generated in 2025 that cannot be realized in 2025.
Until the Company generates sustained levels of profitability, additional valuation allowances may have to be recorded with corresponding adverse impacts on earnings and/or OCI.
Beginning in 2024, we determined that earnings from our non-U.S. subsidiaries are no longer considered to be indefinitely reinvested.
As of December 31, 2025 and 2024, the amounts accrued for the payment of income tax-related interest and penalties included in the Consolidated Statements of Financial Position were not significant. The amounts of interest included in the Consolidated Statements of Operations were not significant for 2025, 2024 and 2023.

As of December 31, 2025, 2024 and 2023, the total amount of unrecognized tax benefits include $975 $651 and $1,088, respectively, that would affect the effective tax rate, if recognized. As of December 31, 2025, these amounts were primarily associated with the amount of research tax credits claimed.
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.
The Organization for Economic Co-operation and Development (OECD) has issued Pillar Two model rules, introducing a new global minimum tax of 15%. While the United States has not adopted Pillar Two, other countries have enacted such legislation or are considering implementation. Given our limited operations in low-tax jurisdictions, Pillar Two has not materially increased our global tax costs. On January 5, 2026, the OECD released a comprehensive package for a “side-by-side arrangement” with respect to Pillar Two. Notably, once adopted, this new guidance will prevent other countries from imposing tax on the U.S. profits of American companies. We will continue to monitor U.S. and international legislative developments, including further announcements on the Side-by-Side package, to assess any potential impacts on our operations.
On July 4, 2025, the President signed into law the One Big Beautiful Bill Act (OBBBA). The OBBBA maintains the 21 percent corporate tax rate and makes permanent many of the beneficial expired and expiring tax provisions originally enacted in the Tax Cuts and Jobs Act of 2017, including the immediate expensing of domestic research and development expenditures, more favorable interest deductibility and 100 percent bonus depreciation with effective dates in 2025. Revisions to the international tax framework are effective in 2026. In the third quarter of 2025, we recorded impacts of the OBBBA, which were not material. In the fourth quarter of 2025, we elected to accelerate into 2025 the deduction of domestic research and development expenditures capitalized and unamortized as of December 31, 2024.

Commercial Aircraft Programs
At December 31, 2025 and 2024, commercial aircraft programs inventory included the following amounts related to the 737 program: deferred production costs of $11,777 and $9,679 and unamortized tooling and other non-recurring costs of $750 and $909. At December 31, 2025, $12,490 of 737 deferred production costs, unamortized tooling and other non-recurring costs is expected to be recovered from units included in the program accounting quantity that have firm orders, and $37 are expected to be recovered from units included in the program accounting quantity that represent expected future orders.
At December 31, 2025 and 2024, commercial aircraft programs inventory included the following amounts related to the 777X program: $4,313 and $3,476 of work in process (including deferred production costs of $651 and $0) and $1,816 and $4,122 of unamortized tooling and other non-recurring costs. In April 2022, we decided to pause production of the 777X-9 during 2022 and 2023, which resulted in abnormal production costs of $513 during the year ended December 31, 2023. In the fourth quarter of 2023, the 777X program resumed production and, as a result, there were no abnormal production costs during the years ended December 31, 2025 and 2024. During the years ended December 31, 2025 and 2024, we determined that estimated costs to complete the 777X program plus the costs already included in 777X inventory exceed estimated revenues from the program. The resulting reach-forward loss of $4,899 in 2025 was recorded as a reduction of deferred production costs, unamortized tooling and other non-recurring costs. The reach-forward loss of $3,499 in 2024 was recorded as a reduction of deferred production costs and other non-recurring costs. The level of profitability on the 777X program will be subject to several factors. These factors include aircraft certification requirements and timing, flight test discoveries, design changes, change incorporation on completed aircraft, production disruption due to labor instability and supply chain disruption, customer considerations, delivery timing and negotiations, further production rate adjustments for the 777X or other commercial aircraft programs, and any change in the accounting quantity. One or more of these factors could result in additional reach-forward losses in future periods.
At December 31, 2025 and 2024, commercial aircraft programs inventory included the following amounts related to the 787 program: deferred production costs of $13,859 and $13,178, supplier advances of $932 and $1,379, and unamortized tooling and other non-recurring costs of $1,366 and $1,370. At December 31, 2025, $13,027 of 787 deferred production costs, unamortized tooling and other non-recurring costs are expected to be recovered from units included in the program accounting quantity that have firm orders, and $2,198 are expected to be recovered from units included in the program accounting quantity that represent expected future orders. We expensed abnormal production costs of $30, $256, and $1,014 during the years ended December 31, 2025, 2024 and 2023.
Commercial aircraft programs inventory included amounts credited in cash or other consideration (early issue sales consideration) to airline customers totaling $6,412 and $5,837 at December 31, 2025 and 2024.

737 MAX Customer Concessions and Other Considerations
During 2024, we recorded an earnings charge of $443, net of insurance recoveries, in connection with estimated considerations to customers for disruption related to the January 2024 737-9 door plug accident and grounding. This charge is reflected in the financial statements as a reduction to Sales of products.
The following table summarizes changes in the 737 MAX customer concessions and other considerations liability during 2025 and 2024.

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 December 31, 2025 and 2024, the high end of the estimated range of reasonably possible remediation costs exceeded our recorded liabilities by $1,171 and $1,002.

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 December 31, 2025, have expiration dates from 2026 through 2033. At December 31, 2025 and 2024, total contractual trade-in commitments were $1,267 and $1,393. As of December 31, 2025 and 2024, we estimated that it was probable we would be obligated to perform on certain of these commitments with net amounts payable to customers totaling $67 and $275 and the fair value of the related trade-in aircraft was $61 and $270.
Financing Commitments
Financing commitments related to aircraft on order, including options and those proposed in sales campaigns, and refinancing of delivered aircraft, totaled $15,229 and $17,124 as of December 31, 2025 and 2024. The estimated earliest potential funding dates for these commitments as of December 31, 2025 are as follows:
Total
2026$2,362

20283,715 
20292,392 
20301,257 
Thereafter1,275 
Total
$15,229 
As of December 31, 2025, $11,904 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 $283 related 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 $3,295 and $2,991 as of December 31, 2025 and 2024.
Company Owned Life Insurance
McDonnell Douglas Corporation insured its executives with Company Owned Life Insurance (COLI), which are life insurance policies with a cash surrender value. Although we do not use COLI currently, these obligations from the merger with McDonnell Douglas are still a commitment at this time. We have loans in place to cover costs paid or incurred to carry the underlying life insurance policies. As of December 31, 2025 and 2024, the cash surrender value was $331 and $342 and the total loans were $303 and $314. As we have the right to offset the loans against the cash surrender value of the policies, we present the net asset in Other assets on the Consolidated Statements of Financial Position as of December 31, 2025 and 2024.
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. The following table summarizes changes in Accounts payable to suppliers participating in supply chain financing programs:
20252024
Beginning balance – January 1$2,703 $2,871 
Additions10,948 12,476 
Reductions for payments made(11,657)(12,644)
Ending balance – December 31$1,994 $2,703 
We do not believe that future changes in the availability of supply chain financing would have a significant impact on our liquidity.
Government Assistance
Certain states and localities in which we operate offer or have offered various business incentives related to investment and/or job creation. Between 2010 and 2016, we received cash grants totaling $346 related to our investment in operations in South Carolina. The grants were recorded in Accrued liabilities and are being amortized, primarily to inventory, over the useful life of the Property, plant and equipment extending through 2052. During 2025 and 2024, we amortized $8 and $9 to Inventories, and recorded a benefit of $10 and $7 in cost of sales. At December 31, 2025 and 2024, Inventories included a benefit of $62 and $64 and Accrued liabilities included a balance of $80 and $87.
We are eligible to claim tax refunds from the State of Missouri and City of Irving, Texas, primarily related to job creation and retention through 2031. During 2025, 2024 and 2023, we received $32, $26, and $22 in cash and recorded a benefit primarily in cost of sales of $27, $30, and $28, respectively. At December 31, 2025 and 2024, Other current assets includes receivables of $26 and $30. As of December 31, 2025, $59 of refunds, plus interest, is subject to clawback if we fail to meet certain conditions, including employment levels.
We are eligible to claim cash grants through 2032 related to operations in Queensland, Australia. During 2023, we received cash of $5, which was recorded as a benefit in cost of sales. During 2024, we received cash of $40 to apply against future eligible expenses, which was recorded in Other long-term liabilities and is subject to clawback if we fail to meet certain conditions, including employment levels. At December 31, 2025, our remaining liability is $23.
Industrial Revenue Bonds (IRB) issued by St. Louis County, the city of St. Charles, Missouri, and the city of Wichita, Kansas, were used to finance the purchase and/or construction of real and personal property at our St. Louis, St. Charles and Wichita sites. Tax benefits associated with IRBs primarily include sales tax exemptions and five to 22-year property tax abatements. We record these properties on our Consolidated Statements of Financial Position. We have also purchased the IRBs, and therefore, are the bondholders as well as the borrower/lessee of the properties purchased with the IRB proceeds. The liabilities and IRB assets are equal and are reported net in the Consolidated Statements of Financial Position. As of December 31, 2025 and 2024, the assets and liabilities associated with the IRBs were $1,054 and $355.
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 could result in losses in future periods. Certain of the fixed-price contracts are for the development of new products, services and related technologies. 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 and 2024, we increased the reach-forward loss on the contract by $60 and $379. The increased reach-forward loss in 2024 was primarily driven by higher than anticipated costs due to engineering design changes related to wiring and other structural requirements. 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 early 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 December 31, 2025. 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 and 2024, we increased the reach-forward loss on the KC-46A Tanker program by $714 and $2,002. The additional reach-forward loss during 2025 was primarily driven by higher estimated manufacturing and engineering costs for production support. As of December 31, 2025, we had approximately $64 of capitalized precontract
costs and $72 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. In the first quarter of 2024, we were awarded a cost-type contract modification totaling $657 for two additional test aircraft plus other scope increases. During 2024, we increased the reach-forward loss by $339 reflecting higher than anticipated production costs and higher costs associated with ongoing design and software development challenges. We recorded an immaterial reach-forward loss in 2025. 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. Flight test and assembly of the remaining EMD units will continue in 2026. 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. The five EMD aircraft have been delivered as of December 31, 2024, and the flight testing is ongoing. In January 2025, the USAF announced an updated acquisition approach for the T-7A Red Hawk that allows the Company to provide a production-ready configuration to the customer prior to low-rate initial production, which better supports the operational needs of the customer and reduces future production risk. In June 2025, the customer ordered four production representative test vehicles. The production portion of the contract now includes production lots for 342 T-7A Red Hawk aircraft and related services that we believe are probable of being exercised. During 2024, we increased the reach-forward loss on the T-7A Red Hawk program by $1,770 primarily reflecting higher estimated supplier costs related to future production lots. We recorded an immaterial reach-forward loss in 2025. At December 31, 2025, we had approximately $377 of capitalized precontract costs and $869 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
The National Aeronautics and Space Administration has contracted us to design and build the CST-100 Starliner spacecraft to transport crews to the International Space Station (ISS) and in the second quarter of 2022, we successfully completed the uncrewed Orbital Flight Test. The 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. During 2024, we increased the reach-forward loss by $523 primarily to reflect schedule delays and higher testing and certification costs as well as higher costs for post certification missions. We recorded an immaterial reach-forward loss in 2025. We and the customer are planning to launch an uncrewed mission during the first half of 2026 and a crewed mission later in 2026. We are continuing to work toward crew certification and resolve the propulsion system anomalies. At December 31, 2025, we had approximately $544 of capitalized precontract costs and $4 of potential termination liabilities to suppliers related to unauthorized future missions. Risk remains that we may record additional losses in future periods.
Severance
During the fourth quarter of 2024, we announced plans to reduce our overall workforce. As a result, in 2024, we recorded $295 of severance benefits payable to employees expected to leave the Company
through involuntary terminations by the first half of 2025. The severance packages were consistent with our ongoing compensation and benefits plans. The remaining liability at December 31, 2025 and 2024, was $0 and $287.

Credit guarantees15 15  $14 $14 
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 15.

Debt Disclosure [Abstract]  
Debt Debt
In August 2025, we entered into a $3,000, 364-day revolving credit agreement expiring in August 2026. This facility replaced the $3,000, three-year revolving credit agreement which was scheduled to terminate in August 2025. The 364-day credit facility has a one-year term out option which allows us to extend the maturity of any borrowings until August 2027. Our legacy $3,000, five-year revolving credit agreement expiring in August 2028 and $4,000, five-year revolving credit agreement expiring in May 2029 each remain in effect. As of December 31, 2025, we had $10,000 available under credit line agreements.
We continue to be in compliance with all covenants contained in our debt and credit facility agreements.
In December 2025, as a result of the Spirit Acquisition, we assumed $3,608 of debt, $2,260 of which we immediately repaid. The remaining debt assumed primarily includes the following notes issued by Spirit Sub: $300 of 3.850% Senior Notes due 2026 (the Spirit 2026 Notes), $700 of 4.600% Senior Notes due 2028 (the Spirit 2028 Notes, and together with the Spirit 2026 Notes, the Spirit Senior Notes) and $230 of 3.250% Exchangeable Notes due 2028 (the Spirit Exchangeable Notes).
The Spirit Exchangeable Notes mature on November 1, 2028, unless earlier exchanged, redeemed or repurchased, and are exchangeable at an initial rate of 6.7067 shares of Boeing common stock per $1,000 principal amount, in whole dollars, of the Spirit Exchangeable Notes. Prior to August 1, 2028, if certain conditions are met, holders of the Spirit Exchangeable Notes may elect to exchange the Spirit Exchangeable Notes. On or after August 1, 2028, the holders of the Spirit Exchangeable Notes may elect to exchange the Spirit Exchangeable Notes without restriction. Upon exchange, we will pay cash and/or deliver shares of Boeing common stock, at our election, to the holders of the Spirit Exchangeable Notes.
In connection with closing of the Spirit Acquisition, The Boeing Company guaranteed the obligations of Spirit Sub with respect to the Spirit Senior Notes, and as a result, each of The Boeing Company and Spirit fully and unconditionally guarantee the Spirit Senior Notes on a senior unsecured basis. The guarantees rank equally in right of payment with all of Boeing’s existing and future senior unsecured indebtedness.

Retirement Benefits, Description [Abstract]  
Postretirement Plans Postretirement Plans
Many of our employees have earned benefits under defined benefit pension plans. The majority of employees that had participated in defined benefit pension plans have transitioned to a company-funded defined contribution retirement savings plan.
We fund our major pension plans through trusts. Pension assets are placed in trust solely for the benefit of the plans’ participants and are structured to maintain liquidity that is sufficient to pay benefit obligations as well as to keep pace over the long-term with the growth of obligations for future benefit payments.
We also have other postretirement benefits (OPB) other than pensions which consist principally of health care coverage for eligible retirees and qualifying dependents, and to a lesser extent, life insurance to certain groups of retirees. Retiree health care is provided principally until age 65 for approximately three-fourths of those participants who are eligible for post-retirement health care coverage. Certain employee groups, including employees covered by most United Auto Workers bargaining agreements, are provided lifetime health care coverage.
The funded status of the plans is measured as the difference between the plan assets at fair value and the projected benefit obligation (PBO). On December 31, 2025, we merged seven of our pension plans to make use of overfunding in certain plans, reducing future required pension plan contributions. We have recognized the aggregate of all overfunded plans in Other assets and the aggregate of all underfunded plans in either Accrued retiree health care or Accrued pension plan liability, net. The portion of the amount by which the actuarial present value of benefits included in the PBO exceeds the fair value of plan assets, payable in the next 12 months, is reflected in Accrued liabilities.
The components of net periodic benefit (income)/cost were as follows:

On December 8, 2025, as part of the Spirit Acquisition, we acquired three defined benefit plans and two post-retirement medical plans. Eligibility for these plans is closed and the defined benefit plans’ accruals are frozen for existing participants.
The following tables show changes in the benefit obligation, plan assets and funded status of both pensions and OPB for the years ended December 31, 2025 and 2024. Benefit obligation balances presented below reflect the PBO for our pension plans and accumulated postretirement benefit obligations (APBO) for our OPB plans.

Assumptions
The following assumptions, which are the weighted average for all plans, are used to calculate the benefit obligation at December 31 of each year and the net periodic benefit cost for the subsequent year.
December 31,202520242023
Discount rate:
Pension5.30 %5.60 %5.10 %
Other postretirement benefits5.00 %5.40 %5.00 %
Expected return on plan assets6.00 %6.00 %6.00 %
Rate of compensation increase4.80 %4.30 %4.30 %
Interest crediting rates for cash balance plans5.00 %5.00 %5.00 %
The discount rate for each plan is determined based on the plans’ expected future benefit payments using a yield curve developed from high quality bonds that are rated as Aa or better by at least half of the four rating agencies utilized as of the measurement date. The yield curve is fitted to yields developed from bonds at various maturity points. Bonds with the 10 percent highest and the 10 percent lowest yields are omitted. The present value of each plan’s benefits is calculated by applying the discount rates to projected benefit cash flows.
The pension fund’s expected return on plan assets assumption is derived from a review of actual historical returns achieved by the pension trust and anticipated future long-term performance of
individual asset classes. While consideration is given to historical returns, the assumption represents a long-term, prospective return. The expected return on plan assets component of the net periodic benefit cost for the upcoming plan year is determined based on the expected return on plan assets assumption and the market-related value of plan assets (MRVA). Since our adoption of the accounting standard for pensions in 1987, we have determined the MRVA based on a five-year moving average of plan assets. As of December 31, 2025, the MRVA was approximately $1,398 more than the fair market value of assets.
Assumed health care cost trend rates were as follows:

Plan Assets
Investment Strategy The overall objective of our pension assets is to earn a rate of return over time to satisfy the benefit obligations of the pension plans and to maintain sufficient liquidity to pay benefits and address other cash requirements of the pension fund. Specific investment objectives for our long-term investment strategy include reducing the volatility of pension assets relative to pension liabilities, achieving a competitive total investment return, achieving diversification between and within asset classes and managing other risks. Investment objectives for each asset class are determined based on specific risks and investment opportunities identified.
We periodically update our long-term, strategic asset allocations. We use various analytics to determine the optimal asset mix and consider plan liability characteristics, liquidity characteristics, funding requirements, expected rates of return and the distribution of returns. A key element of our strategy is to de-risk the plan as the funded status of the plan increases. We identify investment benchmarks to evaluate performance for the asset classes in the strategic asset allocation that are market-based and investable where possible. Actual allocations to each asset class vary from target allocations due to periodic investment strategy changes, market value fluctuations, the duration to fully implement investment allocation positions, and the timing of benefit payments and contributions. Short-term investments and exchange-traded derivatives are used to rebalance the actual asset allocation to the target asset allocation. The asset allocation is monitored and adjusted in accordance with our rebalancing policy. The actual and target allocations by asset class for the pension assets at December 31 were as follows:
Actual AllocationsTarget Allocations

Hedge funds5 6 7 7 
Total100 %100 %100 %100 %
Fixed income securities are invested primarily in a diversified portfolio of long duration instruments as well as Emerging Market, Structured, High Yield and Private Debt. Global equity securities are invested in a diversified portfolio of U.S. and non-U.S. companies, across various industries and market capitalizations.
Private equity investment vehicles are primarily limited partnerships (LPs) that mainly invest in U.S. and non-U.S. leveraged buyout, venture capital, growth and special situation strategies. Real estate and real assets include global private investments that may be held through investments in LPs or other fund structures. Real estate includes, but is not limited to, investments in office, retail, apartment and industrial properties. Real assets include, but are not limited to, investments in natural resources (such as energy, farmland and timber) and infrastructure.
Hedge fund investments seek to capitalize on inefficiencies identified across and within different asset classes or markets. Hedge fund strategy types include, but are not limited to, directional, event driven, relative value and long-short.
Investment managers are retained for explicit investment roles specified by contractual investment guidelines. Certain investment managers are authorized to use derivatives, such as equity or bond futures, swaps, options and currency futures or forwards. Derivatives are used to achieve the desired market exposure of a security or an index, transfer value-added performance between asset classes, achieve the desired currency exposure, adjust portfolio duration or rebalance the total portfolio to the target asset allocation.
As a percentage of total pension assets, derivative net notional amounts were 41.6% and 42.0% for fixed income, including to-be-announced mortgage-backed securities and treasury forwards, and (0.6)% and 0.8% for global equity and commodities at December 31, 2025 and 2024.
Risk Management In managing the pension assets, we review and manage risk associated with funded status risk, interest rate risk, market risk, counterparty risk, liquidity risk and operational risk. Liability matching and asset class diversification are central to our risk management approach and are integral to the overall investment strategy. Further, asset classes are constructed to achieve diversification by investment strategy, by investment manager, by industry or sector and by holding. Investment manager guidelines for publicly traded assets are specified and are monitored regularly through the custodian. Credit parameters for counterparties have been established for managers permitted to trade over-the-counter derivatives. Valuation is governed through several types of procedures, including reviews of manager valuation policies, custodian valuation processes, pricing vendor practices, pricing reconciliation and periodic, security-specific valuation testing.
Fair Value Measurements The following table presents our plan assets using the fair value hierarchy as of December 31, 2025 and 2024. 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.

Fixed income securities are primarily valued upon a market approach, using matrix pricing and considering a security’s relationship to other securities for which quoted prices in an active market may be available, or an income approach, converting future cash flows to a single present value amount. Inputs used in developing fair value estimates include reported trades, broker quotes, benchmark yields and base spreads.
Common/collective/pooled funds are typically common or collective trusts valued at their net asset values (NAVs) that are calculated by the investment manager or sponsor of the fund and have daily or monthly liquidity.
Derivatives included in the table above are over-the-counter and are primarily valued using an income approach with inputs that include benchmark yields, swap curves, cash flow analysis, rating agency data and inter-dealer broker rates. Exchange-traded derivative positions are reported in accordance with changes in daily variation margin which is settled daily and therefore reflected in the payables and receivables portion of the table.
Cash equivalents and other short-term investments (which are used to pay benefits) are held in a separate account which consists of a commingled fund (with daily liquidity) and separately held short-term securities and cash equivalents. All investments in this cash vehicle are valued daily using a market approach with inputs that include quoted market prices for similar instruments. In the event a market price is not available for instruments with an original maturity of one year or less, amortized cost is used as a proxy for fair value. Common and preferred stock equity securities are primarily valued using a market approach based on the quoted market prices of identical instruments.
Private equity and private debt NAV valuations are based on the valuation of the underlying investments, which include inputs such as cost, operating results, discounted future cash flows and market based comparable data. For those investments reported on a one-quarter lagged basis (primarily LPs), we use NAVs adjusted for subsequent cash flows and significant events.
Real estate and real asset NAVs are based on the valuation of the underlying investments, which include inputs such as cost, discounted future cash flows, independent appraisals and market based comparable data. For those investments reported on a one-quarter lagged basis (primarily LPs), NAVs are adjusted for subsequent cash flows and significant events. Publicly traded infrastructure stocks are valued using a market approach based on quoted market prices of identical instruments.
Hedge fund NAVs are generally based on the valuation of the underlying investments. This is primarily done by applying a market or income valuation methodology depending on the specific type of security or instrument held.
Investments in private equity, private debt, real estate, real assets and hedge funds are primarily calculated and reported by the General Partner, fund manager or third-party administrator. Additionally, some investments in fixed income and equity are made via commingled vehicles and are valued in a similar fashion. Pension assets invested in commingled and LP structures rely on the NAV of these investments as the practical expedient for the valuations.
The following tables summarizes the changes of Level 3 assets, reconciled by asset class, held during the years ended December 31, 2025 and 2024. Transfers into and out of Level 3 are reported at the beginning-of-year values.

OPB Plan Assets The majority of OPB plan assets are invested in two commingled index funds (with daily liquidity) which are held at a target allocation of approximately 60% in the equity fund and 40% in
the debt fund. The commingled funds are valued daily at their NAVs which are calculated by the investment manager. The expected rate of return on these assets does not have a material effect on the net periodic benefit cost.
Cash Flows
Contributions Required pension contributions under the Employee Retirement Income Security Act (ERISA), as well as rules governing funding of our non-U.S. pension plans, are not expected to be significant in 2026. We do not expect to make discretionary contributions to our pension plans in 2026.
Estimated Future Benefit Payments The table below reflects the total pension benefits expected to be paid from the plans or from our assets, including both our share of the benefit cost and the participants’ share of the cost, which is funded by participant contributions. OPB payments reflect our portion only.

Termination Provisions
Certain of the pension plans provide that, in the event there is a change in control of the Company which is not approved by the Board of Directors and the plans are terminated within five years thereafter, the assets in the plan first will be used to provide the level of retirement benefits required by ERISA, and then any surplus will be used to fund a trust to continue present and future payments under the postretirement medical and life insurance benefits in our group insurance benefit programs.
Should we terminate certain pension plans under conditions in which the plan’s assets exceed that plan’s obligations, the U.S. government will be entitled to a fair allocation of any of the plan’s assets based on plan contributions that were reimbursed under U.S. government contracts.
Defined Contribution Plans
We provide certain defined contribution plans to all eligible employees. The principal plans are the Company-sponsored 401(k) plans. The expense for these defined contribution plans was $1,602, $1,670 and $1,564 in 2025, 2024 and 2023, respectively.

Share-Based Compensation
Our 2023 Incentive Stock Plan, permits awards of incentive and non-qualified stock options, stock appreciation rights, restricted stock or units, performance restricted stock or units, and other stock and cash-based awards to our employees, officers, directors, consultants, and independent contractors. The aggregate number of shares of our common stock authorized for issuance under the plan is 12,900,000, plus shares that remained or became available under our 2003 Incentive Stock Plan, as amended and restated. Following approval of our 2023 Incentive Stock Plan in 2023, no further awards have been or may be granted under our 2003 Incentive Stock Plan.
Shares issued under the 2023 Incentive Stock Plan will be funded out of treasury shares, except to the extent there are insufficient treasury shares, in which case new shares will be issued. We believe we currently have adequate treasury shares to satisfy these issuances during 2026.
Share-based plans expense is primarily included in Total costs and expenses and General and administrative expense, as well as a portion allocated to production as inventoried costs. The share-based plans expense and related income tax benefit were as follows:

Stock Options
Options have been granted to our executive officers that are generally scheduled to vest and become exercisable three years after the grant date and expire ten years after the grant date. If an executive terminates employment because of retirement, layoff, disability, or death, the executive (or beneficiary) may remain eligible to exercise some or all of their stock options depending on certain age and service conditions. The fair values of the stock options granted were estimated using a Monte-Carlo simulation model using the assumptions presented below. The model includes no expected dividend yield.
In 2025, we granted premium-priced stock options to our executive officers as part of our long-term incentive program. These stock options have an exercise price equal to 120% of the fair market value of our stock on the date of grant.

In February 2025, 2024 and 2023, we granted to our executives 2,244,444, 2,008,499 and 327,523 restricted stock units (RSUs) as part of our long-term incentive program with grant date fair values of $184.53, $204.15 and $214.35 per unit, respectively. In March 2024, we granted to our executive officers 125,432 RSUs with a grant date fair value of $192.94 per unit as part of our long-term incentive program. If an executive terminates employment because of retirement, layoff, disability, or death, the executive (or beneficiary) may receive some or all of their stock units depending on certain age and service conditions. In all other cases, the RSUs will not vest and all rights to the stock units will terminate. These RSUs are included in Long-Term Incentive Program in the table below.
In addition to RSUs awarded under our long-term incentive programs, we granted RSUs to certain executives and employees. As a result of the Spirit Acquisition in December 2025, we exchanged Spirit share-based compensation awards for 164,806 Boeing RSUs, of which 2,682 units are payable in cash. The fair value of these RSUs is $204.71 per unit, of which $16 will be recognized as compensation expense over the remaining service period. These RSUs are included in Other in the table below.
The fair values of all RSUs, except RSUs exchanged for Spirit share-based compensation awards, are estimated using the average of the high and low stock prices on the date of grant.

Performance Restricted Stock Units
In March 2024 and February 2023, we granted 153,306 and 199,899 performance restricted stock units (PRSUs) to our executive officers as part of our long-term incentive program that will result in that number of PRSUs being paid out if the target performance metric is achieved. The PRSUs granted under this program have grant date fair values of $192.94 and $214.35 per unit. The award payout can range from 0% to 200% of the initial PRSU grant based on cumulative free cash flow achievement over a three-year period from January 1 of the grant year as compared to the target set at the start of the performance period. The PRSUs granted in 2024 also include a product safety downward modifier pursuant to which the payout following the end of the three-year performance period may be reduced by 25% or down to 0% if two specified product safety operational goals are not timely completed. The PRSUs granted under this program will vest at the payout amount determined on the third anniversary of the grant date and settle in common stock (on a one-for-one basis). If an executive terminates employment because of retirement, layoff, disability, or death, the executive (or beneficiary) remains eligible under the award and, if the award is earned, may receive some or all of their stock units depending on certain age and service conditions. In all other cases, the PRSUs will not vest and all rights to the stock units will terminate. During the year ended December 31, 2025, there were 20,571 forfeitures and no distributions. At December 31, 2025, there was no unrecognized compensation cost.
Performance-Based Restricted Stock Units
Performance-Based Restricted Stock Units (PBRSUs) are stock units that pay out based on the Company’s total shareholder return (TSR) as compared to a group of peer companies over a three-year period. The award payout can range from 0% to 200% of the initial PBRSU grant. During 2023, these performance awards expired with a payout of 0%. No units were outstanding during 2025.
Employee Stock Purchase Plan
The Company has an employee stock purchase plan which permits eligible employees to purchase Boeing common stock at 95% of the fair market value on the last trading day of each three-month period using payroll deduction. The aggregate number of shares of our common stock authorized for issuance under the plan is 12,000,000. During 2025, approximately 336,831 shares were purchased at an average price of $182.28 per share.
Deferred Compensation
The Company has deferred compensation plans which permit certain employees and executives to defer a portion of their salary, bonus, certain other incentive awards and retirement contributions. Participants can diversify these amounts among 23 investment funds including a Boeing stock unit account.
Total expense/(income) related to deferred compensation was $182, $114 and $188 in 2025, 2024 and 2023, respectively. As of December 31, 2025 and 2024, the deferred compensation liability which is being marked to market was $1,685 and $1,675.

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.

Summary of Derivative Instruments [Abstract]  
Derivative Financial Instruments Derivative Financial Instruments
Cash Flow Hedges
Our cash flow hedges include foreign currency forward contracts, commodity swaps and commodity purchase contracts. We use foreign currency forward contracts to manage currency risk associated with certain expected sales and purchases through 2032. We use commodity derivatives, such as fixed-price purchase commitments and swaps to hedge against potentially unfavorable price changes for commodities used in production. Our commodity contracts hedge forecasted transactions through 2029.
Derivative Instruments Not Receiving Hedge Accounting Treatment
We hold certain foreign currency forward contracts which do not qualify for hedge accounting treatment. At December 31, 2024, we had agreements to purchase and sell aluminum to address long-term
strategic sourcing objectives and non-U.S. business requirements. These agreements were derivative instruments for accounting purposes. The quantities of aluminum in these agreements offset and were priced at prevailing market prices. At December 31, 2025, these agreements have expired and no notional amounts remain.

Based on our portfolio of cash flow hedges, we expect to reclassify gains of $16 (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 facility, 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 December 31, 2025 was $3. For other particular commodity contracts, our counterparties could require collateral posted in an amount determined by our credit ratings. At December 31, 2025, there was no collateral posted related to our derivatives.

Fair Value Disclosures [Abstract]  
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.

Derivatives($43)($43)($218)($218)
Total liabilities($43)($43)($218)($218)
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 price 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 years ended December 31 due to long-lived asset impairment and the fair value of the related assets as of the impairment date:

Operating lease equipment
  15 (5)
Total$2 ($45)$53 ($112)
Level 3 Investments and Other assets were primarily valued using an income approach based on the discounted cash flows associated with the underlying assets. Level 2 and Level 3 Property, plant and equipment were valued based on a third-party valuation using a combination of income and market approaches and adjusted for as-is condition. 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.
Fair Value Disclosures
The fair values and related carrying values of financial instruments that are not required to be remeasured at fair value on the Consolidated Statements of Financial Position at December 31 were as follows:

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 Consolidated Statements of Financial Position, approximate their fair value at December 31, 2025 and 2024. 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 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 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; however, representatives of family members appealed the Court’s decision, which appeal is pending before the U.S. Court of Appeals for the Fifth Circuit.
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, including a motion for class certification on a federal securities class action before 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 59 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.
Our chief operating decision maker is currently our President and Chief Executive Officer (CEO). The primary profitability measurement used by the CEO to review segment operating results is Segment operating (loss)/earnings. The CEO uses Segment operating (loss)/earnings to allocate resources (including employees, financial and capital resources) for each segment predominantly in the annual planning process. Segment operating (loss)/earnings is used to monitor segment results compared to prior period, forecasted results, and the annual plan.
The following table reconciles segment Revenues to Segment operating (loss)/earnings:

Earnings in Equity Method Investments
During the years ended December 31, 2025, 2024 and 2023, our share of income from equity method investments was $33, $104, and $70, respectively. In 2025, 2024 and 2023, earnings from equity method investments were primarily driven by investments held at our BDS segment.
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 December 31, 2025 was $682,207. We expect approximately 13% to be converted to revenue through 2026 and approximately 55% through 2029, 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 (expense)/income 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:

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Our cybersecurity strategy prioritizes detection, analysis and response to known, anticipated or unexpected threats; effective management of security risks; and resiliency against incidents. Our cybersecurity risk management processes include technical security controls, policy enforcement mechanisms, monitoring systems, employee training, contractual arrangements, tools and related services from third-party providers, and management oversight to assess, identify and manage material risks from cybersecurity threats. We implement risk-based controls to protect our information, the information of our customers, suppliers, and other third parties, our information systems, our business operations, and our products and related services. We have adopted security-control principles based on the National Institute of Standards and Technology (NIST) Cybersecurity Framework, other industry-recognized standards, and contractual requirements, as applicable. We also leverage government partnerships, industry and government associations, third-party benchmarking, the results from regular internal and third-party audits, threat intelligence feeds, and other similar resources to inform our cybersecurity processes and allocate resources.
We maintain security programs that include physical, administrative and technical safeguards, and we maintain plans and procedures whose objective is to help us prevent and timely and effectively respond to cybersecurity threats or incidents. Through our cybersecurity risk management process, we continuously monitor cybersecurity vulnerabilities and potential attack vectors to company systems as well as our aerospace products and services, and we evaluate the potential operational and financial effects of any threat and of cybersecurity countermeasures made to defend against such threats. We continue to integrate our cyber practice into our Enterprise Risk Management program and our Compliance Risk Management program, both of which are overseen by our Board of Directors and provide central, standardized frameworks for identifying and tracking cyber-related business and compliance risks across the Company. Risks from cybersecurity threats to our products and services are also overseen by our Board of Directors. In addition, we periodically engage third-party consultants to assist us in assessing, enhancing, implementing, and monitoring our cybersecurity risk management programs and responding to any incidents.
As part of our cybersecurity risk management process, we conduct regular pen-testing and red-teaming to assess the security of our assets as well as “tabletop” exercises during which we simulate cybersecurity incidents to ensure that we are prepared to respond to such an incident and to highlight any areas for potential improvement in our cyber incident preparedness. In addition, all employees are required to complete a mandatory cybersecurity training course on an annual basis and receive monthly phishing simulations to provide “experiential learning” on how to recognize phishing attempts.
We have established a cybersecurity supply chain risk management program, which is a cross-functional program that forms part of our Enterprise Risk Management program and is supported by our security, compliance, and supply chain organizations. Through this evolving program, we assess the risks from cybersecurity threats that impact select suppliers and third-party service providers with whom we share personal identifying and confidential information. We continue to evolve our oversight processes to mature how we identify and manage cybersecurity risks associated with the products or services we procure from such suppliers. We generally require our suppliers to adopt security-control principles based on industry-recognized standards.
We have experienced, and may in the future experience, whether directly or through our supply chain or other channels, cybersecurity incidents. While prior incidents have not materially affected our business strategy, results of operations or financial condition, and although our processes are designed to help prevent, detect, respond to, and mitigate the impact of such incidents, there is no guarantee that a future cyber incident would not materially affect our business strategy, results of operations or financial condition. See “Risks Related to Technology, Security and Business Disruptions” in “Risk Factors” on pages 14 - 15 of this Form 10-K.

Summary of Significant Accounting Policies (Policy)
 12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
Principles of Consolidation and Basis of Presentation
Principles of Consolidation and Basis of Presentation
The Consolidated 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”). These statements include the accounts of all majority-owned subsidiaries and variable interest entities that are required to be consolidated. All significant intercompany accounts and transactions have been eliminated. As described in Note 24, we operate in three reportable segments: Commercial Airplanes (BCA), Defense, Space & Security (BDS), and Global Services (BGS).
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.
Operating Cycle
Operating Cycle
For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year.
Revenue and Related Cost Recognition
Revenue and Related Cost Recognition
Commercial aircraft contracts The majority of our BCA segment revenue is derived from commercial aircraft contracts. For each contract, we determine the transaction price based on the consideration expected to be received. We allocate the transaction price to each commercial aircraft performance obligation based on relative standalone selling prices adjusted by an escalation formula as specified in the customer agreement. Revenue is recognized for each commercial aircraft performance obligation at the point in time when the aircraft is completed and accepted by the customer. We use program accounting to determine the amount reported as cost of sales.
Payments for commercial aircraft sales are received in accordance with the customer agreement, which generally includes a deposit upon order and additional payments in accordance with a payment schedule, with the balance being due immediately prior to or at aircraft delivery. Advances and progress billings (contract liabilities) are normal and customary for commercial aircraft contracts and not considered a significant financing component as they are intended to protect us from the other party failing to adequately complete some or all of its obligations under the contract.
Long-term contracts Substantially all contracts at BDS and certain contracts at BGS are long-term contracts with the U.S. government and other customers that generally extend over several years. Products sales under long-term contracts primarily include fighter jets, rotorcraft, cybersecurity products, surveillance suites, advanced weapons, missile defense, military derivative aircraft, satellite systems and modification of commercial passenger aircraft to cargo freighters. Sales of services under long-term contracts primarily include support and maintenance agreements associated with our commercial and defense products and space travel on Commercial Crew.
For each long-term contract, we determine the transaction price based on the consideration expected to be received. We allocate the transaction price to each distinct performance obligation to deliver a good or service, or a collection of goods and/or services, based on the relative standalone selling prices. A long-term contract will typically represent a single distinct performance obligation due to the highly interdependent and interrelated nature of the underlying goods and/or services and the significant service of integration that we provide. While the scope and price on certain long-term contracts may be modified over their life, the transaction price is based on current rights and obligations under the contract and does not include potential modifications until they are agreed upon with the customer. When applicable, a cumulative adjustment or separate recognition for the additional scope and price may result. Long-term contracts can be negotiated with a fixed price or a price in which we are reimbursed for costs incurred plus an agreed upon profit. The Federal Acquisition Regulations provide guidance on the types of cost that will be reimbursed in establishing the price for contracts with the U.S. government. Certain long-term contracts include in the transaction price variable consideration, such as incentive and award fees, if specified targets are achieved. The amount included in the transaction price represents the expected value, based on a weighted probability, or the most likely amount.
Long-term contract revenue is recognized over the contract term (over time) as the work progresses, either as products are produced or as services are rendered. We generally recognize revenue over time as we perform on long-term contracts because of continuous transfer of control to the customer. For U.S. government contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. Similarly, for non-U.S. government contracts, the customer typically controls the work in process as evidenced either by contractual termination clauses or by our rights to payment of the transaction price associated with work performed to date on products or services that do not have an alternative use to the Company.
The accounting for long-term contracts involves a judgmental process of estimating total revenues, costs and profit for each performance obligation. Cost of sales is recognized as incurred. The amount reported as revenues is determined by adding a proportionate amount of the estimated profit to the amount reported as cost of sales. Recognizing revenue as costs are incurred provides an objective measure of progress on the long-term contract and thereby best depicts the extent of transfer of control to the customer.
For long-term contracts for which revenue is recognized over time, 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/(loss) from operations from changes in estimated losses on unexercised options for the years ended December 31:
202520242023
Decrease to Revenue($916)($2,794)($1,706)
Decrease/increase to Earnings/(loss) from operations
($1,377)($6,562)($2,943)
Decrease/increase to Diluted earnings/(loss) per share
($1.53)($9.83)($5.43)
Significant adjustments during the three years ended December 31, 2025, 2024 and 2023, included losses on KC-46A Tanker, VC-25B, T-7A Red Hawk, MQ-25, and Commercial Crew programs.
Due to the significance of judgment in the estimation process, changes in underlying operational assumptions, inability to implement planned risk mitigation plans, failure to achieve productivity targets, supplier shortages, quality issues and/or pricing issues, inflationary trends, or other circumstances may adversely or positively affect financial performance in future periods.
Payments under long-term contracts may be received before or after revenue is recognized. The U.S. government customer typically withholds payment of a small portion of the contract price until contract completion. Therefore, long-term contracts typically generate Unbilled receivables (contract assets) but may generate Advances and progress billings (contract liabilities). Long-term contract Unbilled receivables and Advances and progress billings are not considered a significant financing component because they are intended to protect either the customer or the Company in the event that some or all of the obligations under the contract are not completed.
Commercial spare parts contracts Certain contracts at our BGS segment include sales of commercial spare parts. For each contract, we determine the transaction price based on the consideration expected to be received. The spare parts have discrete unit prices that represent fair value. We generally consider each spare part to be a separate performance obligation. Revenue is recognized for each commercial spare part performance obligation at the point in time of delivery to the customer. We may provide our customers with a right to return a commercial spare part where a customer may receive a full or partial refund, a credit applied to amounts owed, a different product in exchange, or any combination of these items. We consider the potential for customer returns in the estimated transaction price. The amount reported as cost of sales is recorded at average cost. Payments for commercial spare parts sales are typically received shortly after delivery.
Other service revenue contracts Certain contracts at our BGS segment are for sales of services to commercial customers including maintenance, training, and digital solutions and analytics. We recognize revenue for these service performance obligations over time as the services are rendered. The method of measuring progress (such as straight-line or billable amount) varies depending upon which method best depicts the transfer of control to the customer based on the type of service performed. Cost of sales is recorded as incurred.
Concession sharing arrangements We account for sales concessions to our customers in consideration of their purchase of products and services as a reduction of the transaction price and the revenue that is recognized for the related performance obligations. The sales concessions incurred may be partially reimbursed by certain suppliers in accordance with concession sharing arrangements. We record these reimbursements, which are presumed to represent reductions in the price of the vendor’s products or services, as a reduction in Cost of products.
Unbilled receivables and advances and progress billings Unbilled receivables (contract assets) arise when the Company recognizes revenue for amounts which cannot yet be billed under terms of the contract with the customer. Advances and progress billings (contract liabilities) arise when the Company receives payments from customers in advance of recognizing revenue. The amount of Unbilled receivables or Advances and progress billings is determined for each contract.
Financial services revenue We record financial services revenue associated with sales-type leases, operating leases and loans in Sales of services on the Consolidated Statements of Operations. For sales-type leases, we recognize selling profit or loss at lease inception if collection of the lease payments is probable. For sales-type leases, we record financing receivables at lease inception. A financing receivable is recorded at the aggregate of future lease payments, estimated residual value of the leased equipment, and any deferred incremental direct costs less unearned income. Income is recognized over the life of the lease to approximate a level rate of return on the net investment. For notes receivable, we record financing receivables net of any unamortized discounts and deferred
incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note.
Income recognition is generally suspended for financing receivables that are uncollectible. We determine that a financing receivable is uncollectible when, based on current information and events, it is probable that we will be unable to collect amounts due according to the original contractual terms. We determine a financing receivable is past due when cash has not been received upon the due date specified in the contract.
We evaluate the collectability of financing receivables at commencement and on a recurring basis. If a financing receivable is determined to be uncollectible, the customer is categorized as non-accrual status. When a customer is in non-accrual status at commencement, sales-type lease revenue is deferred until substantially all cash has been received or the customer is removed from non-accrual status. If we have a note receivable with a customer that is in non-accrual status, or a sales-type lease with a customer that changes to non-accrual status after commencement, we recognize contractual interest income as payments are received to the extent there is sufficient collateral and payments exceed past due principal payments.
Residual values, which are reviewed periodically, represent the estimated amount we expect to receive at lease termination from the disposition of the leased equipment. Actual residual values realized could differ from these estimates. Declines in estimated residual value that are deemed other-than-temporary are recognized in the period in which the declines occur.
For operating leases, revenue on leased aircraft and equipment is recorded on a straight-line basis over the term of the lease. Operating lease assets, included in Financing receivables and operating lease equipment, net, are recorded at cost and depreciated to an estimated residual value using the straight-line method over the period that we project we will hold the asset. We periodically review our estimates of residual value and recognize forecasted changes by prospectively adjusting depreciation expense. We record assets held for sale at the lower of carrying value or fair value less costs to sell. We evaluate for impairment assets under operating leases when events or changes in circumstances indicate that the expected undiscounted cash flow from the asset may be less than the carrying value. When we determine that impairment is indicated for an asset, the amount of impairment expense recorded is the excess of the carrying value over the fair value of the asset.
Reinsurance Our wholly-owned insurance subsidiary, Astro Ltd., participates in a reinsurance pool for workers’ compensation. The member agreements and practices of the reinsurance pool minimize any participating members’ individual risk. Reinsurance revenues were $99, $110 and $163 during 2025, 2024 and 2023, respectively. Reinsurance costs related to premiums and claims paid to the reinsurance pool were $123, $123 and $181 during 2025, 2024 and 2023, respectively. Revenues and costs are presented net in Cost of products and Cost of services in the Consolidated Statements of Operations.
Research and Development
Research and Development
Research and development includes costs incurred for experimentation, design and testing, as well as bid and proposal efforts related to government products and services, which are expensed as incurred unless the costs are related to certain contractual arrangements with customers. Costs that are incurred pursuant to such contractual arrangements are recorded over the period that revenue is recognized, consistent with our long-term contract accounting policy. We have certain research and development arrangements with customers that meet the conditions for best efforts research and development accounting. Accordingly, the amounts funded by the customer are recognized as an offset to our research and development expense rather than as contract revenues. Research and development expense, net included bid and proposal costs of $161, $179 and $188 in 2025, 2024 and 2023, respectively.
Share-Based Compensation
Share-Based Compensation
We provide various forms of share-based compensation to our employees. For awards settled in shares, we measure compensation expense based on the grant-date fair value net of estimated forfeitures. For awards settled in cash, or that may be settled in cash, we measure compensation expense based on the fair value at each reporting date net of estimated forfeitures. The expense is recognized over the requisite service period, which is generally the vesting period of the award.
Income Taxes
Income Taxes
Provisions for U.S. federal, state and local, and non-U.S. income taxes are calculated on reported Earnings/(loss) before income taxes based on current tax law and also include, in the current period, the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions.
The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. We record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. Tax-related interest and penalties are classified as a component of Income tax (expense)/benefit.
We also assess the likelihood that we will be able to recover our deferred tax assets against future sources of taxable income and reduce the carrying amounts of deferred tax assets by recording a valuation allowance if, based on the available evidence, it is more likely than not that all or a portion of such assets will not be realized. Changes in our estimates and judgments regarding realization of deferred tax assets may result in an increase or decrease to our tax expense and/or other comprehensive income, which would be recorded in the period in which the change occurs.
Postretirement Plans
Postretirement Plans
Many of our employees have earned benefits under defined benefit pension plans. The majority of employees that had participated in defined benefit pension plans have transitioned to a company-funded defined contribution retirement savings plan. We also provide postretirement benefit plans other than pensions, consisting principally of health care coverage to eligible retirees and qualifying dependents. Benefits under the pension and other postretirement benefit plans are generally based on age at retirement and years of service and, for some pension plans, benefits are also based on the employee’s annual earnings. The net periodic cost of our pension and other postretirement plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the long-term rate of asset return and medical trend (rate of growth for medical costs). Actuarial gains and losses, which occur when actual experience differs from actuarial assumptions, are reflected in Shareholders’ equity (net of taxes). If actuarial gains and losses exceed 10 percent of the greater of plan assets or plan liabilities, we amortize them over the average expected future lifetime of participants. The funded status of our pension and postretirement plans is reflected on the Consolidated Statements of Financial Position.
Postemployment Plans
Postemployment Plans
We record a liability for postemployment benefits, such as severance or job training, when payment is probable and the amount is reasonably estimable.
Environmental Remediation
Environmental Remediation
We are subject to federal and state requirements for protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties and/or insurance carriers. Our policy is to accrue and charge to current expense identified exposures related to environmental remediation sites when it is probable that a liability has been incurred and the amount can be reasonably estimated. The amount of the liability is based on our best estimate or the low end of a range of reasonably possible exposure for investigation, cleanup and monitoring costs to be incurred. Estimated remediation costs are not discounted to present value as the timing of payments cannot be reasonably estimated. We may be able to recover a portion of the remediation costs from insurers or other third parties. Such recoveries are recorded when realization of the claim for recovery is deemed probable.
Cash and Cash Equivalents
Cash and Cash Equivalents
Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits and other money market instruments, which have original maturities of three months or less. We aggregate our cash balances by bank where conditions for right of set-off are met, and reclassify any negative balances, consisting mainly of uncleared checks, to Accounts payable. Negative balances reclassified to Accounts payable were $127 and $110 at December 31, 2025 and 2024.
Inventories
Inventories
Inventoried costs on commercial aircraft programs and long-term contracts include direct engineering, production and tooling and other non-recurring costs, and applicable overhead, which includes fringe benefits, production related indirect and plant management salaries and plant services, not in excess of estimated net realizable value. To the extent a material amount of such costs are related to an abnormal event or are fixed costs not appropriately attributable to our programs or contracts, they are expensed in the current period rather than inventoried. Inventoried costs include amounts relating to programs and contracts with long-term production cycles, a portion of which is not expected to be realized within one year. Included in inventory for federal government contracts is an allocation of allowable costs related to manufacturing process reengineering.
Commercial aircraft programs inventory includes deferred production costs and supplier advances. Deferred production costs represent actual costs incurred for production of early units that exceed the estimated average cost of all units in the program accounting quantity. Higher production costs are experienced at the beginning of a new or derivative aircraft program. Units produced early in a program require substantially more effort (labor and other resources) than units produced later in a program because of volume efficiencies and the effects of learning. We expect that these deferred costs will be fully recovered when all units included in the accounting quantity are delivered as the expected unit cost for later deliveries is below the estimated average cost of all units in the program. Supplier advances represent payments for parts we have contracted to receive from suppliers in the future. As parts are received, supplier advances are amortized to work in process.
The determination of net realizable value of long-term contract costs is based upon quarterly reviews that estimate costs to be incurred to complete all contract requirements. When actual contract costs and the estimate to complete exceed total estimated contract revenues, a loss provision is recorded. The determination of net realizable value of commercial aircraft program costs is based upon quarterly program reviews that estimate revenue and cost to be incurred to complete the program accounting quantity. When estimated costs to complete exceed estimated program revenues to go, a program loss provision is recorded in the current period for the estimated loss on all undelivered units in the accounting quantity.
Used aircraft purchased by our BCA segment and general stock materials are stated at cost not in excess of net realizable value. Spare parts inventory is stated at lower of average unit cost or net realizable value. We review our commercial spare parts and general stock materials quarterly to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends, expected production usage, and the size and age of the aircraft fleet using the part. Impaired inventories are charged to Cost of products in the period the impairment occurs.
Included in inventory for commercial aircraft programs are amounts paid or credited in cash, or other consideration to certain airline customers, that are referred to as early issue sales consideration. Early issue sales consideration is recognized as a reduction to revenue when the delivery of the aircraft under contract occurs. If an airline customer does not perform and take delivery of the contracted aircraft, we believe that we would have the ability to recover amounts paid. However, to the extent early issue sales consideration exceeds advances and is not considered to be otherwise recoverable, it would be written off against revenue of the current period.
Precontract Costs
Precontract Costs
We may, from time to time, incur costs in excess of the amounts required for existing contracts. If we determine the costs are probable of recovery from future orders, then we capitalize the precontract costs we incur, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories in the accompanying Consolidated Statements of Financial Position. Should future orders not materialize or we determine the costs are no longer probable of recovery, the capitalized costs would be written off.
Property, Plant and Equipment
Property, Plant and Equipment
Property, plant and equipment are recorded at cost, including applicable construction-period interest, less accumulated depreciation and are depreciated principally over the following estimated useful lives: new buildings and land improvements, from 10 to 40 years; and new machinery and equipment, from four to 20 years. The principal method of depreciation for buildings and land improvements is 150% declining balance and for machinery and equipment is sum-of-the-years’ digits. Capitalized internal use software is included in Other assets, net and amortized using the straight line method over five years. Capitalized costs of software purchased as a service are included in Other assets, net and amortized using the straight line method over the term of the hosting arrangement, which is typically no greater than 10 years. We periodically evaluate the appropriateness of remaining depreciable lives assigned to long-lived assets, including assets that may be subject to a management plan for disposition.
Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Long-lived assets held for use are subject to an impairment assessment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
Leases
Leases
We determine if an arrangement is, or contains, a lease under which we are the lessee at the inception date. Operating lease assets are included in Other assets, net, with the related liabilities included in Accrued liabilities and Other long-term liabilities. Assets under finance leases, which primarily represent computer equipment, are included in Property, plant and equipment, net, with the related liabilities included in Short-term debt and current portion of long-term debt and Long-term debt on the Consolidated Statements of Financial Position.
Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease
assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as fair market value adjustments, utilities and maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term.
We have real property lease agreements with lease and non-lease components which are accounted for as a single lease component.
Asset Retirement Obligations
Asset Retirement Obligations
We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning and contractual lease restoration obligations. Recorded amounts are not material.
We also have known conditional asset retirement obligations, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the Consolidated Financial Statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability’s fair value. In addition, there may be conditional asset retirement obligations that we have not yet discovered (e.g. asbestos may exist in certain buildings but we have not become aware of it through the normal course of business), and therefore, these obligations also have not been included in the Consolidated Financial Statements.
Goodwill and Other Acquired Intangibles
Goodwill and Other Acquired Intangibles
Goodwill and other acquired intangible assets with indefinite lives are not amortized, but are tested for impairment annually and when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Our annual testing date is April 1.
We test goodwill for impairment by performing a qualitative assessment or using a quantitative test. If we choose to perform a qualitative assessment and determine it is more likely than not that the carrying value of the net assets is more than the fair value of the related operations, the quantitative test is then performed; otherwise, no further testing is required. For operations where the quantitative test is used, we compare the carrying value of net assets to the estimated fair value of the related operations. If the fair value is determined to be less than carrying value, the shortfall up to the carrying value of the goodwill represents the amount of goodwill impairment.
We performed our annual goodwill impairment test as of April 1, 2025, using a qualitative assessment. We determined the fair value of each of our reporting units substantially exceeded their respective carrying values. Our Military Aircraft reporting unit within our BDS segment had goodwill of $1,295 and a negative carrying value at December 31, 2025.
Indefinite-lived intangibles consist of in-process research and development (IPR&D) acquired in a business combination. IPR&D is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. IPR&D is reclassified to finite-lived acquired intangible assets when a project is completed and then amortized on a straight-line basis over the asset’s estimated useful life. We test IPR&D for impairment by comparing the carrying value to current projections of related discounted cash flows. Any excess carrying value over the amount of discounted cash flows represents the amount of the impairment.
Our finite-lived acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as follows: developed technology, from three to 10 years; product know-how, from nine to 13 years; customer base, from seven to 17 years; distribution rights, from eight to 24 years; and other, from three to 32 years. We evaluate the potential impairment of finite-lived acquired intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
Investments
Investments
Time deposits are held-to-maturity investments that are carried at cost.
Available-for-sale debt investments include commercial paper, corporate notes and U.S. government agency securities. Available-for-sale debt investments are recorded at fair value, and unrealized gains and losses are recorded, net of tax, as a component of accumulated other comprehensive income. Realized gains and losses on available-for-sale debt investments are recognized based on the specific identification method. Available-for-sale debt investments are assessed for impairment quarterly.
The equity method of accounting is used to account for investments for which we have the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of an investee of between 20% and 50%. The cumulative earnings approach is used for cash flow classification of distributions received from equity method investments.
Other Equity investments are recorded at fair value, with gains and losses recorded through net earnings. Equity investments without readily determinable fair value are measured at cost, less impairments, plus or minus observable price changes. Equity investments without readily determinable fair value are assessed for impairment quarterly.
We classify investment income and loss on our Consolidated Statements of Operations based on whether the investment is operating or non-operating in nature. Operating investments align strategically and are integrated with our operations. Earnings from operating investments, including our share of income or loss from equity method investments, dividend income from other equity investments, and any impairments or gain/loss on the disposition of these investments, are recorded in Income from operating investments, net. Non-operating investments are those we hold for non-strategic purposes. Earnings from non-operating investments, including interest and dividends on marketable securities, and any impairments or gain/loss on the disposition of these investments are recorded in Other income, net.
Derivatives
Derivatives
All derivative instruments are recognized in the financial statements and measured at fair value regardless of the purpose or intent of holding them. We principally use derivative instruments to manage a variety of market risks. For our cash flow hedges, the derivative’s gain or loss is initially reported in comprehensive income and is subsequently reclassified into earnings in the same period(s) during which the hedged forecasted transaction affects earnings.
We hold certain other derivative instruments for economic purposes. These derivative instruments are derivatives for accounting purposes but are not designated as hedges for accounting purposes. For derivative instruments not designated for hedge accounting treatment, the changes in their fair value are recorded in earnings immediately.
Allowances for Losses on Certain Financial Assets
Allowances for Losses on Certain Financial Assets
We establish allowances for credit losses on accounts receivable, unbilled receivables, financing receivables and certain other financial assets. The adequacy of these allowances is assessed quarterly through consideration of factors such as customer credit ratings, bankruptcy filings, published or estimated credit default rates, age of the receivable, expected loss rates and collateral exposures. Collateral exposure is the excess of the carrying value of a financial asset over the fair value of the related collateral. We determine the creditworthiness of our customers by assigning internal credit ratings based upon publicly available information and information obtained directly from the customers. Our rating categories are comparable to those used by major credit rating agencies.
Financing receivables are collateralized by security in the related asset. We use a median calculated from published collateral values from multiple third-party aircraft value publications based on the type and age of the aircraft to determine the fair value of aircraft collateral. Under certain circumstances, we apply judgment based on the attributes 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 outside publications.
We have entered into agreements with certain customers and suppliers to whom we have provided financing that would entitle us to look beyond the specific collateral underlying the receivable for purposes of determining the collateral exposure. Should the proceeds from the sale of the underlying collateral asset resulting from a default condition be insufficient to cover the carrying value of our receivable (creating a shortfall condition), these agreements would, for example, permit us to take the actions necessary to sell or retain certain other assets in which the customer or supplier has an equity interest and use the proceeds to cover the shortfall.
Commercial Aircraft Trade-in Commitments
Commercial Aircraft Trade-in Commitments
In conjunction with signing a definitive agreement for the sale of new commercial aircraft (Sale 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.
Exposure related to trade-in commitments may take the form of:
(1)adjustments to revenue for the difference between the contractual trade-in price in the definitive agreement and our best estimate of the fair value of the trade-in aircraft as of the date of such agreement, which would be recognized upon delivery of the Sale Aircraft, and/or
(2)charges to cost of products for adverse changes in the fair value of trade-in aircraft that occur subsequent to signing of a definitive agreement for Sale Aircraft but prior to the purchase of the used trade-in aircraft. Estimates based on current aircraft values would be included in Accrued liabilities.
The fair value of trade-in aircraft is determined using aircraft-specific data such as model, age and condition, market conditions for specific aircraft and similar models, and multiple valuation sources. This process uses our assessment of the market for each trade-in aircraft, which in most instances begins years before the return of the aircraft. There are several possible markets in which we continually pursue opportunities to place used aircraft. These markets include, but are not limited to, the resale market, which could potentially include the cost of long-term storage; the leasing market, with the potential for refurbishment costs to meet the leasing customer’s requirements; or the scrap market. Trade-in aircraft valuation varies significantly depending on which market we determine is most likely for each aircraft. On a quarterly basis, we update our valuation analysis based on the actual activities associated with placing each aircraft into a market or using current published third-party aircraft valuations based on the type and age of the aircraft, adjusted for individual attributes and known conditions.
Warranties
Warranties
In conjunction with certain product sales, we provide warranties that cover factors such as non-conformance to specifications and defects in material and design. The majority of our warranties are issued by our BCA segment. Generally, aircraft sales are accompanied by a three to four-year standard warranty for systems, accessories, equipment, parts, and software manufactured by us or manufactured to certain standards under our authorization. These warranties are included in the estimates to complete the related programs. On occasion we have made commitments beyond the standard warranty obligation to correct fleet-wide major issues of a particular model, resulting in additional accrued warranty expense. Warranties issued by our BDS segment principally relate to sales of military aircraft and weapons systems. These sales are generally accompanied by a six month to two-year warranty period and cover systems, accessories, equipment, parts and software manufactured by us to certain contractual specifications. Estimated costs related to standard warranties are recorded in the period in which the related product delivery occurs. The warranty liability recorded at each balance sheet date reflects the estimated number of months of warranty coverage outstanding for products delivered times the average of historical monthly warranty payments, as well as additional amounts for certain major warranty issues that exceed a normal claims level. Estimated costs of these additional warranty issues are considered changes to the initial liability estimate.
We provide guarantees to certain commercial aircraft customers which include compensation provisions for failure to meet specified aircraft performance targets. We account for these performance guarantees as warranties. The estimated liability for these warranties is based on known and anticipated operational characteristics and forecasted customer operation of the aircraft relative to contractually specified performance targets, and anticipated settlements when contractual remedies are not specified. Estimated payments are recorded as a reduction of revenue at delivery of the related aircraft. We have agreements that require certain suppliers to compensate us for amounts paid to customers for failure of supplied equipment to meet specified performance targets. Claims against suppliers under these agreements are included in Inventories and recorded as a reduction in Cost of products at delivery of the related aircraft. These performance warranties and claims against suppliers are included in estimates to complete the related programs.
Supplier Penalties
Supplier Penalties
We may incur penalties to suppliers under certain circumstances such as a contract termination. We record an accrual for supplier penalties when an event occurs that makes it probable we will incur a supplier penalty and the amount is reasonably estimable.
Guarantees
Guarantees
At the inception of a guarantee, we record a liability in Accrued liabilities for the fair value of the guarantee. For credit guarantees, the liability is equal to the present value of the expected loss. We determine the expected loss by multiplying the creditor’s default rate by the guarantee amount reduced by the expected recovery, if applicable. We also recognize a liability for the expected contingent loss at inception and adjust it each quarter.
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 Exchangeable Notes. Under the if-converted method, if the potential conversion of our Mandatory convertible preferred stock and/or 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 Exchangeable Notes, net of tax.
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.

(1)    During the year ended December 31, 2025, the tax effect in this category was primarily driven by state taxes in California (greater than 50 percent).
(2)    We recorded a tax expense of $59 in the foreign jurisdictions related to the Digital Aviation Solutions Divestiture. The German Digital Aviation Solutions Divestiture rate benefit was due to the statutory rate difference of ($203) (7.7)% and a participation exemption of ($548) (20.8)%. The Swedish rate benefit was entirely due to a participation exemption.
(3)    Related to the Digital Aviation Solutions Divestiture, in the U.S., we recorded a Global Intangible Low-Taxed Income inclusion, which is offset by a decrease in the federal valuation allowance, resulting in no federal tax expense.
(4)    The worldwide valuation allowance recorded in tax expense was $120 with $50 federal tax benefit shown on this line, $161 state tax expense included in State and Local Tax line item, and $9 foreign tax expense included in Foreign Tax Effects.
