Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	1. A. Nature of operations Information in our financial statements and related commentary are presented in the following categories: Machinery, Power & Energy (MP&E) — The company defines MP&E as Caterpillar Inc. and its subsidiaries, excluding Financial Products. MP&E’s information relates to the design, manufacturing and marketing of its products. Financial Products — The company defines Financial Products as our finance and insurance subsidiaries, primarily Caterpillar Financial Services Corporation (Cat Financial) and Caterpillar Insurance Holdings Inc. (Insurance Services). Financial Products’ information relates to the financing to customers and dealers for the purchase and lease of Caterpillar and other equipment. B. Basis of presentation In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of (a) the consolidated results of operations for the three months ended March 31, 2026 and 2025, (b) the consolidated comprehensive income for the three months ended March 31, 2026 and 2025, (c) the consolidated financial position at March 31, 2026 and December 31, 2025, (d) the consolidated changes in shareholders’ equity for the three months ended March 31, 2026 and 2025 and (e) the consolidated cash flow for the three months ended March 31, 2026 and 2025. The financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Interim results are not necessarily indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with the audited financial statements and notes thereto included in our company’s annual report on Form 10-K for the year ended December 31, 2025 (2025 Form 10-K). The December 31, 2025 financial position data included herein is derived from the audited consolidated financial statements included in the 2025 Form 10-K but does not include all disclosures required by U.S. GAAP. Certain amounts for prior periods have been reclassified to conform to the current period financial statement presentation. Cat Financial has end-user customers and dealers that are variable interest entities (VIEs) of which we are not the primary beneficiary. Our maximum exposure to loss from our involvement with these VIEs is limited to the credit risk inherently present in the financial support that we have provided. Credit risk was evaluated and reflected in our financial statements as part of our overall portfolio of finance receivables and related allowance for credit losses. See Note 11 for further discussions on a consolidated VIE. Long-term receivables - trade and other in the Statement of Financial Position includes $850 million and $377 million at March 31, 2026 and December 31, 2025, respectively, for recoveries from over-payments made during the importation process. Current assets: Receivables - trade and other includes $154 million at March 31, 2026. There were no amounts included in Current assets: Receivables - trade and other at December 31, 2025. On February 20, 2026, the U.S. Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (“IEEPA”) on goods imported into the United States were unauthorized. As of March 31, 2026, total IEEPA tariff costs were approximately $1.0 billion. The ruling did not address potential refunds, and therefore the ultimate availability, timing and amount of any potential refunds of these tariffs is highly uncertain. Based on the current facts and circumstances, we have determined that recovery of any funds is not probable. We will continue to monitor developments related to U.S. and foreign import and export policies that could impact our consolidated results of operations, financial position and cash flows.
Revenue	Trade receivables represent amounts due from dealers and end users for the sale of our products, and include amounts due from wholesale inventory financing provided by Cat Financial for a dealer’s purchase of inventory. We recognize trade receivables from dealers and end users in Receivables – trade and other and Long-term receivables – trade and other in the Consolidated Statement of Financial Position. Trade receivables from dealers and end users were $9,558 million, $9,402 million and $7,864 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively. Long-term trade receivables from dealers and end users were $1,060 million, $1,006 million and $640 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively. For certain contracts, we invoice for payment when contractual milestones are achieved. We recognize a contract asset when a sale is recognized before achieving the contractual milestone for invoicing. We reduce the contract asset when we invoice for payment and recognize a corresponding trade receivable. Contract assets are included in Prepaid expenses and other current assets in the Consolidated Statement of Financial Position. Contract assets were $233 million, $297 million and $238 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively. We invoice in advance of recognizing the sale of certain products. We recognize advanced customer payments as a contract liability in Customer advances and Other liabilities in the Consolidated Statement of Financial Position. Contract liabilities were $6,032 million, $4,678 million and $2,745 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively. We reduce the contract liability when revenue is recognized.
Share-Based Compensation	Accounting for stock-based compensation requires that the cost resulting from all stock-based payments be recognized in the financial statements based on the grant date fair value of the award. Our stock-based compensation consists of stock options, restricted stock units (RSUs) and performance-based restricted stock units (PRSUs).
Derivatives	Our earnings and cash flow are subject to fluctuations due to changes in foreign currency exchange rates, interest rates, commodity prices, and certain deferred compensation plan liabilities. Our Risk Management Policy allows for the use of derivative financial instruments to prudently manage foreign currency exchange rate, interest rate, commodity price and certain deferred compensation plan liability exposures. Our policy specifies that derivatives are not to be used for speculative purposes. Derivatives that we use are primarily foreign currency forward, option and cross currency contracts, interest rate contracts, commodity forward and option contracts and total return swap contracts. Our derivative activities are subject to the management, direction and control of our senior financial officers. We present at least annually to the Audit Committee of the Board of Directors on our risk management practices, including our use of financial derivative instruments. We recognize all derivatives at their fair value in the Consolidated Statement of Financial Position. On the date the derivative contract is entered into, we designate the derivative as (1) a hedge of the fair value of a recognized asset or liability (fair value hedge), (2) a hedge of a forecasted transaction or the variability of cash flow (cash flow hedge) or (3) an undesignated instrument. We record in current earnings changes in the fair value of a derivative that is qualified, designated and highly effective as a fair value hedge, along with the gain or loss on the hedged recognized asset or liability that is attributable to the hedged risk. For foreign exchange contracts designated as fair value hedges, the interim settlements are excluded from the effectiveness assessment and are recognized under a systematic and rational method over the life of the hedging instrument within Interest expense. We record in AOCI changes in the fair value of a derivative that is qualified, designated and highly effective as a cash flow hedge, to the extent effective, in the Consolidated Statement of Financial Position until we reclassify them to earnings in the same period or periods during which the hedged transaction affects earnings. We report changes in the fair value of undesignated derivative instruments in current earnings. We classify cash flows from designated derivative financial instruments within the same category as the item being hedged in the Consolidated Statement of Cash Flow. We include cash flows from undesignated derivative financial instruments in the investing category in the Consolidated Statement of Cash Flow. We formally document all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as fair value hedges to specific assets and liabilities in the Consolidated Statement of Financial Position and linking cash flow hedges to specific forecasted transactions or variability of cash flow. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the designated derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flow of hedged items. When a derivative is determined not to be highly effective as a hedge or the underlying hedged transaction is no longer probable, we discontinue hedge accounting prospectively, in accordance with the derecognition criteria for hedge accounting. Foreign currency exchange rate risk Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of sales made and costs incurred in foreign currencies. Movements in foreign currency rates also affect our competitive position as these changes may affect business practices and/or pricing strategies of non-U.S.-based competitors. Additionally, we have balance sheet positions denominated in foreign currencies, thereby creating exposure to movements in exchange rates. Our MP&E operations purchase, manufacture and sell products in many locations around the world. As we have a diversified revenue and cost base, we manage our future foreign currency cash flow exposure on a net basis. We use foreign currency forward and option contracts to manage unmatched foreign currency cash inflow and outflow. Our objective is to minimize the risk of exchange rate movements that would reduce the U.S. dollar value of our foreign currency cash flow. Our policy allows for managing anticipated foreign currency cash flow for up to approximately five years. As of March 31, 2026, the maximum term of these outstanding contracts at inception was approximately 60 months. We generally designate as cash flow hedges at inception of the contract any foreign currency forward or option contracts that meet the requirements for hedge accounting and the maturity extends beyond the current quarter-end. We perform designation on a specific exposure basis to support hedge accounting. The remainder of MP&E foreign currency contracts are undesignated. In managing foreign currency risk for our Financial Products operations, our objective is to minimize earnings volatility resulting from conversion and the remeasurement of net foreign currency balance sheet positions and future transactions denominated in foreign currencies. Our policy allows the use of foreign currency forward, option and cross currency contracts to offset the risk of currency mismatch between our assets and liabilities and exchange rate risk associated with future transactions denominated in foreign currencies. Our foreign currency forward and option contracts are primarily undesignated. We designate fixed-to-fixed cross currency contracts as cash flow hedges to protect against movements in exchange rates on foreign currency fixed-rate assets and liabilities. We designate float-to-float cross currency contracts as fair value hedges to protect against movements in exchange rates on floating-rate assets and liabilities. Interest rate risk Interest rate movements create a degree of risk by affecting the amount of our interest payments and the value of our fixed-rate debt. Our practice is to use interest rate contracts to manage our exposure to interest rate changes. Our MP&E operations generally use fixed-rate debt as a source of funding. Our objective is to minimize the cost of borrowed funds. Our policy allows us to enter into fixed-to-floating interest rate contracts and forward rate agreements to meet that objective. We designate fixed-to-floating interest rate contracts as fair value hedges at inception of the contract, and we designate certain forward rate agreements as cash flow hedges at inception of the contract. Financial Products operations has a match-funding policy that addresses interest rate risk by aligning the interest rate profile (fixed or floating rate and duration) of Cat Financial’s debt portfolio with the interest rate profile of our receivables portfolio within predetermined ranges on an ongoing basis. In connection with that policy, we use interest rate derivative instruments to modify the debt structure to match assets within the receivables portfolio. This matched funding reduces the volatility of margins between interest-bearing assets and interest-bearing liabilities, regardless of which direction interest rates move. Our policy allows us to use fixed-to-floating, floating-to-fixed and floating-to-floating interest rate contracts to meet the match-funding objective. We designate fixed-to-floating interest rate contracts as fair value hedges to protect debt against changes in fair value due to changes in the benchmark interest rate. We designate most floating-to-fixed interest rate contracts as cash flow hedges to protect against the variability of cash flows due to changes in the benchmark interest rate. If we liquidate fixed-to-floating or floating-to-fixed interest rate contracts at MP&E or Financial Products, we amortize any deferred gains or losses into earnings over the remaining term of the previously hedged item. Commodity price risk Commodity price movements create a degree of risk by affecting the price we must pay for certain raw materials. Our policy is to use commodity forward and option contracts to manage the commodity risk and reduce the cost of purchased materials. Our MP&E operations purchase base and precious metals embedded in the components we purchase from suppliers. Our suppliers pass on to us price changes in the commodity portion of the component cost. In addition, we are subject to price changes on energy products such as natural gas and diesel fuel purchased for operational use. Our objective is to minimize volatility in the price of these commodities. Our policy allows us to enter into commodity forward and option contracts to lock in the purchase price of a portion of these commodities within a five-year horizon. All such commodity forward and option contracts are undesignated. Deferred compensation plan liability risk We are also exposed to variability in compensation expense related to certain non-qualified deferred compensation obligations to employees. We utilize total return swaps to economically hedge this exposure to offset the related compensation expense. All such total return swap contracts are undesignated.
Investments	We have investments in certain debt and equity securities, which we record at fair value and primarily include in Other assets in the Consolidated Statement of Financial Position. Short-term and long-term investments are held with high quality institutions and, by policy, the amount of credit exposure to any one institution is limited. We classify debt securities primarily as available-for-sale. We include the unrealized gains and losses arising from the revaluation of available-for-sale debt securities, net of applicable deferred income taxes, in equity (AOCI in the Consolidated Statement of Financial Position). We include the unrealized gains and losses arising from the revaluation of the equity securities in Other income (expense) in the Consolidated Statement of Results of Operations. We generally determine realized gains and losses on sales of investments using the specific identification method for available-for-sale debt and equity securities and include them in Other income (expense) in the Consolidated Statement of Results of Operations.
Guarantees and Product Warranty	We have dealer performance guarantees and third-party performance guarantees that do not limit potential payment to end users related to indemnities and other commercial contractual obligations. In addition, we have entered into contracts involving industry standard indemnifications that do not limit potential payment. For these unlimited guarantees, we are unable to estimate a maximum potential amount of future payments that could result from claims made. We determine our product warranty liability by applying historical claim rate experience to the current field population and dealer inventory. Generally, we base historical claim rates on actual warranty experience for each product by machine model/engine size by customer or dealer location (inside or outside North America). We develop specific rates for each product shipment month and update them monthly based on actual warranty claim experience.
Segments	Our Executive Office is comprised of a Chief Executive Officer (CEO), four Group Presidents, a Chief Financial Officer (CFO), a Chief Legal Officer and General Counsel and a Chief Human Resources Officer. The Group Presidents and CFO are accountable for a related set of end-to-end businesses that they manage. The Chief Legal Officer and General Counsel leads the Law, Security and Public Policy Division. The Chief Human Resources Officer leads the Human Resources Organization. The CEO allocates resources and manages performance at the Group President/CFO level. As such, the CEO serves as our Chief Operating Decision Maker (CODM), and operating segments are primarily based on the Group President/CFO reporting structure. Three of our operating segments, Power & Energy, Construction Industries, and Resource Industries are led by Group Presidents. One operating segment, Financial Products, is led by the CFO who also has responsibility for Corporate Services. Corporate Services is a cost center primarily responsible for the performance of certain support functions globally and to provide centralized services; it does not meet the definition of an operating segment. One Group President leads one smaller operating segment that is included in the All Other Segment. The Law, Security and Public Policy Division and the Human Resources Organization are cost centers and do not meet the definition of an operating segment. Effective January 1, 2026, we made the following change to segment reporting. The change was made to reflect change in organizational accountabilities and refinements to our internal reporting. •Responsibility for business strategy, product design, product management and development, manufacturing, marketing and sales and product support for diesel-electric, hybrid and battery-electric locomotives and components and other rail-related products and services, including remanufacturing and leasing moved from Power & Energy to Resource Industries. Effective July 1, 2025, we made the following changes to segment reporting. These changes were made to reflect changes in organizational accountabilities and refinements to our internal reporting. •Responsibility for business strategy, product design, product management and development, manufacturing, marketing and sales and product support for and sourcing of wear and maintenance components and related parts moved from All Other Segment to Resource Industries. •Responsibility for business strategy, product design, product management and development, manufacturing and product support for electronics and control systems moved from Resource Industries to All Other Segment. •Responsibility for research and development for automation, electronics and software for machines and engines moved from Resource Industries to the All Other Segment. Segment information for 2025 has been retrospectively adjusted to conform to the 2026 presentation. B. Description of segments We have five operating segments, of which four are reportable segments. Following is a brief description of our reportable segments and the business activities included in the All Other Segment: Power & Energy: A segment primarily responsible for supporting customers using reciprocating engines, turbines and related services across industries serving Power Generation, Oil and Gas and Industrial applications, including marine applications and product support of on-highway engines. Responsibilities include business strategy, product design, product management, development and testing, manufacturing, marketing and sales and product support. The product and services portfolio includes turbines, centrifugal gas compressors, and turbine-related services; reciprocating engine-powered generator sets; integrated systems and solutions used in the electric power generation industry; reciprocating engines, drivetrain and integrated systems and solutions for the oil and gas industry; reciprocating engines, drivetrain and integrated systems and solutions supplied to the industrial industry as well as Caterpillar machines; and electrified powertrain and zero-emission power sources and service solutions. Responsibilities also include the remanufacturing of Caterpillar reciprocating engines and engine and machine components and remanufacturing services for other companies. Inter-segment sales are a source of revenue for this segment. Construction Industries: A segment primarily responsible for supporting customers using machinery in infrastructure and building construction applications. Responsibilities include business strategy, product design, product management and development, manufacturing, marketing and sales and product support. The product portfolio includes asphalt pavers; backhoe loaders; cold planers; compactors; compact track loaders; forestry machines; material handlers; motor graders; pipelayers; road reclaimers; skid steer loaders; telehandlers; track-type loaders; track-type tractors (small, medium); track excavators (mini, small, medium, large); wheel excavators; wheel loaders (compact, small, medium); and related parts and work tools. Inter-segment sales are a source of revenue for this segment. Resource Industries: A segment primarily responsible for supporting customers using machinery in mining, heavy construction and quarry and aggregates as well as customers using locomotives and rail-related products and services. Responsibilities include business strategy, product design, product management and development, manufacturing, marketing and sales and product support. The product portfolio includes large track-type tractors; large mining trucks; hard rock vehicles; electric rope shovels; draglines; hydraulic shovels; rotary drills; large wheel loaders; off-highway trucks; articulated trucks; wheel tractor scrapers; wheel dozers; landfill compactors; soil compactors; wide-body trucks; select work tools; machinery components; wear and maintenance components and related parts; diesel-electric, hybrid and battery-electric locomotives and components and other rail-related products and services, including remanufacturing and leasing. In addition, Resource Industries sells technology products and services to provide customers fleet management, equipment management analytics, autonomous machine capabilities, safety services and mining performance solutions. Resource Industries also manages areas that provide services to other parts of the company, including strategic procurement, lean center of excellence, integrated component design and manufacturing and research and development for hydraulic systems and cabs. Inter-segment sales are a source of revenue for this segment. Financial Products Segment: Provides financing alternatives to customers and dealers around the world for Caterpillar products and services, as well as financing for power generation facilities that incorporate Caterpillar products. Financing plans include operating and finance leases, revolving charge accounts, installment sale contracts, repair/rebuild financing, working capital loans and wholesale financing plans. The segment also provides insurance and risk management products and services that help customers and dealers manage their business risk. Insurance and risk management products offered include physical damage insurance, inventory protection plans, extended service coverage and maintenance plans for machines and engines, and dealer property and casualty insurance. The various forms of financing, insurance and risk management products offered to customers and dealers help support the purchase and lease of Caterpillar equipment. The segment also earns revenues from Machinery, Power & Energy, but the related costs are not allocated to operating segments. Financial Products’ segment profit is determined on a pretax basis and includes other income/expense items. All Other Segment: Primarily includes activities such as: business strategy; product management and development; parts distribution; integrated logistics solutions; electronics and control systems; distribution services responsible for dealer development and administration, including a wholly owned dealer in Japan; dealer portfolio management and ensuring the most efficient and effective distribution of machines, engines and parts; brand management and marketing strategy; research and development for automation, electronics and software for machines and engines and digital investments for new customer and dealer solutions that integrate data analytics with state-of-the-art digital technologies while transforming the buying experience. Results for the All Other Segment are included as a reconciling item between reportable segments and consolidated external reporting. C. Segment measurement and reconciliations We determine the segment profit of Power & Energy, Construction Industries, Resource Industries, and our All Other Segment on a pretax basis and exclude most interest expense and certain other income (expense) items. We determine Financial Products Segment profit on a pretax basis and include other income (expense) items. Our CODM evaluates the operating performance of the segments using segment profit as it provides insight into the financial health of each segment. The CODM reviews this metric regularly to compare the profitability of segments, identify trends, and evaluate which segments require additional resources or strategic adjustments. The CODM uses segment profit to support the allocation of resources predominantly in the annual budget and forecasting process. Additionally, the CODM monitors forecast-to-actual variances, focusing on areas where performance deviates from expectations, when evaluating the performance of each segment and making decisions about allocating capital and other resources to each segment. There are several methodology differences between our segment reporting and our external reporting. The following is a list of the more significant methodology differences: •For Power & Energy, Construction Industries, Resource Industries, and our All Other Segment net assets generally include inventories, receivables, property, plant and equipment, goodwill, intangibles, accounts payable and customer advances. We generally manage at the corporate level liabilities other than accounts payable and customer advances, and we do not include these in segment operations. Financial Products Segment assets generally include all categories of assets. •We value segment inventories and cost of sales using a current cost methodology. •We amortize goodwill allocated to segments using a fixed amount based on a 20-year useful life. This methodology difference only impacts segment assets. We do not include goodwill amortization expense in segment profit. In addition, we have allocated to segments only a portion of goodwill for certain acquisitions made in 2011 or later. •We generally manage currency exposures for operating segments, other than Financial Products, at the corporate level and do not include in segment profit or segment assets the effects of changes in exchange rates on results of operations and financial position within the year. We report the net difference created in the translation of revenues and costs between exchange rates used for U.S. GAAP reporting and exchange rates used for segment reporting as a methodology difference. •We do not include stock-based compensation expense in segment profit. •Postretirement benefit expenses are split; segments are generally responsible for service costs, with the remaining elements of net periodic benefit cost included as a methodology difference. Reconciling items are created based on accounting differences between segment reporting and our consolidated external reporting. Please refer to pages 28-30 for financial information regarding significant reconciling items. Most of our reconciling items are self-explanatory given the above explanations. For the reconciliation of profit, we have grouped the reconciling items as follows: •Corporate costs: These costs are related to corporate requirements primarily for compliance and legal functions for the benefit of the entire organization. •Restructuring income/costs: May include costs for employee separation, long-lived asset impairments, contract terminations and (gains)/losses on divestitures. These costs are included in Other operating (income) expenses except for defined-benefit plan curtailment losses and special termination benefits, which are included in Other income (expense). Restructuring costs also include other exit-related costs, which may consist of accelerated depreciation, inventory write-downs, building demolition, equipment relocation and project management costs and LIFO inventory decrement benefits from inventory liquidations at closed facilities, all of which are primarily included in Cost of goods sold. See Note 20 for more information. •Methodology differences: See previous discussion of significant accounting differences between segment reporting and consolidated external reporting. •Timing: Timing differences in the recognition of costs between segment reporting and consolidated external reporting. For example, we report certain costs on the cash basis for segment reporting and the accrual basis for consolidated external reporting.
Allowance for Credit Losses	Allowance for credit losses Portfolio segments A portfolio segment is the level at which Cat Financial develops a systematic methodology for determining its allowance for credit losses. Cat Financial's portfolio segments and related methods for estimating expected credit losses are as follows: Customer Cat Financial provides loans and finance leases to end-user customers primarily for the purpose of financing new and used Caterpillar machinery, engines and equipment for commercial use. Cat Financial also provides financing for power generation facilities that incorporate Caterpillar products. The average original term of Cat Financial's customer finance receivables portfolio was approximately 51 months with an average remaining term of approximately 28 months as of March 31, 2026. Cat Financial typically maintains a security interest in financed equipment and generally requires physical damage insurance coverage on the financed equipment, both of which provide Cat Financial with certain rights and protections. If Cat Financial's collection efforts fail to bring a defaulted account current, Cat Financial generally can repossess the financed equipment, after satisfying local legal requirements, and sell it within the Caterpillar dealer network or through third-party auctions. Cat Financial estimates the allowance for credit losses related to its customer finance receivables based on loss forecast models utilizing probabilities of default and the estimated loss given default based on past loss experience adjusted for current conditions and reasonable and supportable forecasts capturing country and industry-specific economic factors. During the three months ended March 31, 2026, Cat Financial's forecasts reflected a continuation of global market uncertainty and actions by global central banks aimed at balancing economic growth and managing inflation. Cat Financial believes the economic forecasts employed represent reasonable and supportable forecasts, followed by a reversion to long-term trends. Dealer Cat Financial provides financing to Caterpillar dealers on a secured and unsecured basis in the form of wholesale financing plans and retail loans. Cat Financial's wholesale financing plans provide financing to dealers for their new Caterpillar equipment inventory and rental fleets. The retail loans to Caterpillar dealers are primarily for working capital. Cat Financial estimates the allowance for credit losses for dealer finance receivables based on historical loss rates with consideration of current economic conditions and reasonable and supportable forecasts. In general, Cat Financial's Dealer portfolio segment has not historically experienced large increases or decreases in credit losses based on changes in economic conditions due to its close working relationships with the dealers and their financial strength. Therefore, Cat Financial made no adjustments to historical loss rates during the three months ended March 31, 2026. Classes of finance receivables Cat Financial further evaluates portfolio segments by the class of finance receivables, which is defined as a level of information (below a portfolio segment) in which the finance receivables have the same initial measurement attribute and a similar method for assessing and monitoring credit risk. Cat Financial's classes, which align with management reporting for credit losses, are as follows: •North America - Finance receivables originated in the United States and Canada. •EAME - Finance receivables originated in Europe, Africa, the Middle East and Eurasia. •Asia/Pacific - Finance receivables originated in Australia, New Zealand, China, Japan, Southeast Asia and India. •Latin America - Finance receivables originated in Mexico and Central and South American countries. •Mining - Finance receivables originated worldwide related to large mining customers. •Power - Finance receivables originated worldwide related to large power customers of Caterpillar electrical power generation, gas compression and co-generation systems and non-Caterpillar equipment that is powered by these systems. Receivable balances, including accrued interest, are written off against the allowance for credit losses when, in the judgment of management, they are considered uncollectible (generally upon repossession of the collateral). Generally, the amount of the write-off is determined by comparing the fair value of the collateral, less cost to sell, to the amortized cost of the receivable. Subsequent recoveries, if any, are credited to the allowance for credit losses when received.
Fair Value Measurement	Fair value measurements The guidance on fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. This guidance also specifies a fair value hierarchy based upon the observability of inputs used in valuation techniques. Observable inputs (highest level) reflect market data obtained from independent sources, while unobservable inputs (lowest level) reflect internally developed market assumptions. In accordance with this guidance, fair value measurements are classified under the following hierarchy: •Level 1 — Quoted prices for identical instruments in active markets. •Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable in active markets. •Level 3 — Model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable. When available, we use quoted market prices to determine fair value, and we classify such measurements within Level 1. In some cases where market prices are not available, we make use of observable market based inputs to calculate fair value, in which case the measurements are classified within Level 2. If quoted or observable market prices are not available, fair value is based upon valuations in which one or more significant inputs are unobservable, including internally developed models that use, where possible, current market-based parameters such as interest rates, yield curves and currency rates. These measurements are classified within Level 3. We classify fair value measurements according to the lowest level input or value-driver that is significant to the valuation. We may therefore classify a measurement within Level 3 even though there may be significant inputs that are readily observable. Fair value measurement includes the consideration of nonperformance risk. Nonperformance risk refers to the risk that an obligation (either by a counterparty or Caterpillar) will not be fulfilled. For financial assets traded in an active market (Level 1 and certain Level 2), the nonperformance risk is included in the market price. For certain other financial assets and liabilities (certain Level 2 and Level 3), our fair value calculations have been adjusted accordingly. Investments in debt and equity securities We have investments in certain debt and equity securities that are recorded at fair value. Fair values for our U.S. treasury bonds and large capitalization value and smaller company growth equity securities are based upon valuations for identical instruments in active markets. Fair values for other government debt securities, corporate debt securities and mortgage-backed debt securities are based upon models that take into consideration such market-based factors as recent sales, risk-free yield curves and prices of similarly rated bonds. In addition, Insurance Services has an equity investment in a real estate investment trust (REIT) which is recorded at fair value based on the net asset value (NAV) of the investment and is not classified within the fair value hierarchy. See Note 8 for additional information on our investments in debt and equity securities. Derivative financial instruments The fair value of interest rate contracts is primarily based on a standard industry accepted valuation model that utilizes the appropriate market-based forward swap curves and zero-coupon interest rates to determine discounted cash flows. The fair value of foreign currency and commodity forward, option and cross currency contracts is based on standard industry accepted valuation models that discount cash flows resulting from the differential between the contract price and the market-based forward rate. The fair value of total return swap contracts is primarily based on valuing the underlying securities or funds using pricing by industry providers and the average Secured Overnight Financing Rate (SOFR) plus a spread. In addition to the methods and assumptions we use to record the fair value of financial instruments as discussed in the Fair value measurements section above, we use the following methods and assumptions to estimate the fair value of our financial instruments: Cash and cash equivalents Carrying amount approximates fair value. We classify cash and cash equivalents as Level 1. See Consolidated Statement of Financial Position. Restricted cash and short-term investments Carrying amount approximates fair value. We include restricted cash and short-term investments in Prepaid expenses and other current assets in the Consolidated Statement of Financial Position. We classify these instruments as Level 1. See Note 8 for additional information. Finance receivables We estimate fair value by discounting the future cash flows using current rates, representative of receivables with similar remaining maturities. Wholesale inventory receivables We estimate fair value by discounting the future cash flows using current rates, representative of receivables with similar remaining maturities. Short-term borrowings Carrying amount approximates fair value. We classify short-term borrowings as Level 1. See Consolidated Statement of Financial Position. Long-term debt We estimate fair value for fixed and floating rate debt based on quoted market prices.
Restructuring Costs	Our accounting for employee separations is dependent upon how the particular program is designed. For voluntary programs, we recognize eligible separation costs at the time of employee acceptance unless the acceptance requires explicit approval by the company. For involuntary programs, we recognize eligible costs when management has approved the program, the affected employees have been properly notified and the costs are estimable.

In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of (a) the consolidated results of operations for the three months ended March 31, 2026 and 2025, (b) the consolidated comprehensive income for the three months ended March 31, 2026 and 2025, (c) the consolidated financial position at March 31, 2026 and December 31, 2025, (d) the consolidated changes in shareholders’ equity for the three months ended March 31, 2026 and 2025 and (e) the consolidated cash flow for the three months ended March 31, 2026 and 2025. The financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).

Interim results are not necessarily indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with the audited financial statements and notes thereto included in our company’s annual report on Form 10-K for the year ended December 31, 2025 (2025 Form 10-K).

The December 31, 2025 financial position data included herein is derived from the audited consolidated financial statements included in the 2025 Form 10-K but does not include all disclosures required by U.S. GAAP. Certain amounts for prior periods have been reclassified to conform to the current period financial statement presentation.

Cat Financial has end-user customers and dealers that are variable interest entities (VIEs) of which we are not the primary beneficiary. Our maximum exposure to loss from our involvement with these VIEs is limited to the credit risk inherently present in the financial support that we have provided. Credit risk was evaluated and reflected in our financial statements as part of our overall portfolio of finance receivables and related allowance for credit losses. See Note 11 for further discussions on a consolidated VIE.

Long-term receivables - trade and other in the Statement of Financial Position includes $850 million and $377 million at March 31, 2026 and December 31, 2025, respectively, for recoveries from over-payments made during the importation process. Current assets: Receivables - trade and other includes $154 million at March 31, 2026. There were no amounts included in Current assets: Receivables - trade and other at December 31, 2025.

On February 20, 2026, the U.S. Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (“IEEPA”) on goods imported into the United States were unauthorized. As of March 31, 2026, total IEEPA tariff costs were approximately $1.0 billion. The ruling did not address potential refunds, and therefore the ultimate availability, timing and amount of any potential refunds of these tariffs is highly uncertain. Based on the current facts and circumstances, we have determined that recovery of any funds is not probable. We will continue to monitor developments related to U.S. and foreign import and export policies that could impact our consolidated results of operations, financial position and cash flows.

Revenue

Trade receivables represent amounts due from dealers and end users for the sale of our products, and include amounts due from wholesale inventory financing provided by Cat Financial for a dealer’s purchase of inventory. We recognize trade receivables from dealers and end users in Receivables – trade and other and Long-term receivables – trade and other in the Consolidated Statement of Financial Position. Trade receivables from dealers and end users were $9,558 million, $9,402 million and $7,864 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively. Long-term trade receivables from dealers and end users were $1,060 million, $1,006 million and $640 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively.

For certain contracts, we invoice for payment when contractual milestones are achieved. We recognize a contract asset when a sale is recognized before achieving the contractual milestone for invoicing. We reduce the contract asset when we invoice for payment and recognize a corresponding trade receivable. Contract assets are included in Prepaid expenses and other current assets in the Consolidated Statement of Financial Position. Contract assets were $233 million, $297 million and $238 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively.

We invoice in advance of recognizing the sale of certain products. We recognize advanced customer payments as a contract liability in Customer advances and Other liabilities in the Consolidated Statement of Financial Position. Contract liabilities were $6,032 million, $4,678 million and $2,745 million as of March 31, 2026, December 31, 2025 and December 31, 2024, respectively. We reduce the contract liability when revenue is recognized.

Share-Based Compensation

Accounting for stock-based compensation requires that the cost resulting from all stock-based payments be recognized in the financial statements based on the grant date fair value of the award. Our stock-based compensation consists of stock options, restricted stock units (RSUs) and performance-based restricted stock units (PRSUs).

Derivatives

Our earnings and cash flow are subject to fluctuations due to changes in foreign currency exchange rates, interest rates, commodity prices, and certain deferred compensation plan liabilities. Our Risk Management Policy allows for the use of derivative financial instruments to prudently manage foreign currency exchange rate, interest rate, commodity price and certain deferred compensation plan liability exposures. Our policy specifies that derivatives are not to be used for speculative purposes. Derivatives that we use are primarily foreign currency forward, option and cross currency contracts, interest rate contracts, commodity forward and option contracts and total return swap contracts. Our derivative activities are subject to the management, direction and control of our senior financial officers. We present at least annually to the Audit Committee of the Board of Directors on our risk management practices, including our use of financial derivative instruments.

We recognize all derivatives at their fair value in the Consolidated Statement of Financial Position. On the date the derivative contract is entered into, we designate the derivative as (1) a hedge of the fair value of a recognized asset or liability (fair value hedge), (2) a hedge of a forecasted transaction or the variability of cash flow (cash flow hedge) or (3) an undesignated instrument. We record in current earnings changes in the fair value of a derivative that is qualified, designated and highly effective as a fair value hedge, along with the gain or loss on the hedged recognized asset or liability that is attributable to the hedged risk. For foreign exchange contracts designated as fair value hedges, the interim settlements are excluded from the effectiveness assessment and are recognized under a systematic and rational method over the life of the hedging instrument within Interest expense. We record in AOCI changes in the fair value of a derivative that is qualified, designated and highly effective as a cash flow hedge, to the extent effective, in the Consolidated Statement of Financial Position until we reclassify them to earnings in the same period or periods during which the hedged transaction affects earnings. We report changes in the fair value of undesignated derivative instruments in current earnings. We classify cash flows from designated derivative financial instruments within the same category as the item being hedged in the Consolidated Statement of Cash Flow. We include cash flows from undesignated derivative financial instruments in the investing category in the Consolidated Statement of Cash Flow.

We formally document all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as fair value hedges to specific assets and liabilities in the Consolidated Statement of Financial Position and linking cash flow hedges to specific forecasted transactions or variability of cash flow.

We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the designated derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flow of hedged items. When a derivative is determined not to be highly effective as a hedge or the underlying hedged transaction is no longer probable, we discontinue hedge accounting prospectively, in accordance with the derecognition criteria for hedge accounting.

Foreign currency exchange rate risk

Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of sales made and costs incurred in foreign currencies. Movements in foreign currency rates also affect our competitive position as these changes may affect business practices and/or pricing strategies of non-U.S.-based competitors. Additionally, we have balance sheet positions denominated in foreign currencies, thereby creating exposure to movements in exchange rates.

Our MP&E operations purchase, manufacture and sell products in many locations around the world. As we have a diversified revenue and cost base, we manage our future foreign currency cash flow exposure on a net basis. We use foreign currency forward and option contracts to manage unmatched foreign currency cash inflow and outflow. Our objective is to minimize the risk of exchange rate movements that would reduce the U.S. dollar value of our foreign currency cash flow. Our policy allows for managing anticipated foreign currency cash flow for up to approximately five years. As of March 31, 2026, the maximum term of these outstanding contracts at inception was approximately 60 months.

We generally designate as cash flow hedges at inception of the contract any foreign currency forward or option contracts that meet the requirements for hedge accounting and the maturity extends beyond the current quarter-end. We perform designation on a specific exposure basis to support hedge accounting. The remainder of MP&E foreign currency contracts are undesignated.

In managing foreign currency risk for our Financial Products operations, our objective is to minimize earnings volatility resulting from conversion and the remeasurement of net foreign currency balance sheet positions and future transactions denominated in foreign currencies. Our policy allows the use of foreign currency forward, option and cross currency contracts to offset the risk of currency mismatch between our assets and liabilities and exchange rate risk associated with future transactions denominated in foreign currencies. Our foreign currency forward and option contracts are primarily undesignated. We designate fixed-to-fixed cross currency contracts as cash flow hedges to protect against movements in exchange rates on foreign currency fixed-rate assets and liabilities. We designate float-to-float cross currency contracts as fair value hedges to protect against movements in exchange rates on floating-rate assets and liabilities.

Interest rate risk

Interest rate movements create a degree of risk by affecting the amount of our interest payments and the value of our fixed-rate debt. Our practice is to use interest rate contracts to manage our exposure to interest rate changes.

Our MP&E operations generally use fixed-rate debt as a source of funding. Our objective is to minimize the cost of borrowed funds. Our policy allows us to enter into fixed-to-floating interest rate contracts and forward rate agreements to meet that objective. We designate fixed-to-floating interest rate contracts as fair value hedges at inception of the contract, and we designate certain forward rate agreements as cash flow hedges at inception of the contract.

Financial Products operations has a match-funding policy that addresses interest rate risk by aligning the interest rate profile (fixed or floating rate and duration) of Cat Financial’s debt portfolio with the interest rate profile of our receivables portfolio within predetermined ranges on an ongoing basis. In connection with that policy, we use interest rate derivative instruments to modify the debt structure to match assets within the receivables portfolio. This matched funding reduces the volatility of margins between interest-bearing assets and interest-bearing liabilities, regardless of which direction interest rates move.

Our policy allows us to use fixed-to-floating, floating-to-fixed and floating-to-floating interest rate contracts to meet the match-funding objective. We designate fixed-to-floating interest rate contracts as fair value hedges to protect debt against changes in fair value due to changes in the benchmark interest rate. We designate most floating-to-fixed interest rate contracts as cash flow hedges to protect against the variability of cash flows due to changes in the benchmark interest rate.

If we liquidate fixed-to-floating or floating-to-fixed interest rate contracts at MP&E or Financial Products, we amortize any deferred gains or losses into earnings over the remaining term of the previously hedged item.

Commodity price risk

Commodity price movements create a degree of risk by affecting the price we must pay for certain raw materials. Our policy is to use commodity forward and option contracts to manage the commodity risk and reduce the cost of purchased materials.

Our MP&E operations purchase base and precious metals embedded in the components we purchase from suppliers. Our suppliers pass on to us price changes in the commodity portion of the component cost. In addition, we are subject to price changes on energy products such as natural gas and diesel fuel purchased for operational use.

Our objective is to minimize volatility in the price of these commodities. Our policy allows us to enter into commodity forward and option contracts to lock in the purchase price of a portion of these commodities within a five-year horizon. All such commodity forward and option contracts are undesignated.

Deferred compensation plan liability risk

We are also exposed to variability in compensation expense related to certain non-qualified deferred compensation obligations to employees. We utilize total return swaps to economically hedge this exposure to offset the related compensation expense. All such total return swap contracts are undesignated.

Investments

We have investments in certain debt and equity securities, which we record at fair value and primarily include in Other assets in the Consolidated Statement of Financial Position. Short-term and long-term investments are held with high quality institutions and, by policy, the amount of credit exposure to any one institution is limited.

We classify debt securities primarily as available-for-sale. We include the unrealized gains and losses arising from the revaluation of available-for-sale debt securities, net of applicable deferred income taxes, in equity (AOCI in the Consolidated Statement of Financial Position). We include the unrealized gains and losses arising from the revaluation of the equity securities in Other income (expense) in the Consolidated Statement of Results of Operations. We generally determine realized gains and losses on sales of investments using the specific identification method for available-for-sale debt and equity securities and include them in Other income (expense) in the Consolidated Statement of Results of Operations.

Guarantees and Product Warranty

We have dealer performance guarantees and third-party performance guarantees that do not limit potential payment to end users related to indemnities and other commercial contractual obligations. In addition, we have entered into contracts involving industry standard indemnifications that do not limit potential payment. For these unlimited guarantees, we are unable to estimate a maximum potential amount of future payments that could result from claims made.

We determine our product warranty liability by applying historical claim rate experience to the current field population and dealer inventory. Generally, we base historical claim rates on actual warranty experience for each product by machine model/engine size by customer or dealer location (inside or outside North America). We develop specific rates for each product shipment month and update them monthly based on actual warranty claim experience.

Segments

Our Executive Office is comprised of a Chief Executive Officer (CEO), four Group Presidents, a Chief Financial Officer (CFO), a Chief Legal Officer and General Counsel and a Chief Human Resources Officer. The Group Presidents and CFO are accountable for a related set of end-to-end businesses that they manage. The Chief Legal Officer and General Counsel leads the Law, Security and Public Policy Division. The Chief Human Resources Officer leads the Human Resources Organization. The CEO allocates resources and manages performance at the Group President/CFO level. As such, the CEO serves as our Chief Operating Decision Maker (CODM), and operating segments are primarily based on the Group President/CFO reporting structure.

Three of our operating segments, Power & Energy, Construction Industries, and Resource Industries are led by Group Presidents. One operating segment, Financial Products, is led by the CFO who also has responsibility for Corporate Services. Corporate Services is a cost center primarily responsible for the performance of certain support functions globally and to provide centralized services; it does not meet the definition of an operating segment. One Group President leads one smaller operating segment that is included in the All Other Segment. The Law, Security and Public Policy Division and the Human Resources Organization are cost centers and do not meet the definition of an operating segment.

Effective January 1, 2026, we made the following change to segment reporting. The change was made to reflect change in organizational accountabilities and refinements to our internal reporting.

•Responsibility for business strategy, product design, product management and development, manufacturing, marketing and sales and product support for diesel-electric, hybrid and battery-electric locomotives and components and other rail-related products and services, including remanufacturing and leasing moved from Power & Energy to Resource Industries.

Effective July 1, 2025, we made the following changes to segment reporting. These changes were made to reflect changes in organizational accountabilities and refinements to our internal reporting.

•Responsibility for business strategy, product design, product management and development, manufacturing, marketing and sales and product support for and sourcing of wear and maintenance components and related parts moved from All Other Segment to Resource Industries.

•Responsibility for business strategy, product design, product management and development, manufacturing and product support for electronics and control systems moved from Resource Industries to All Other Segment.

•Responsibility for research and development for automation, electronics and software for machines and engines moved from Resource Industries to the All Other Segment.

Segment information for 2025 has been retrospectively adjusted to conform to the 2026 presentation.

B. Description of segments

We have five operating segments, of which four are reportable segments. Following is a brief description of our reportable segments and the business activities included in the All Other Segment:

Power & Energy: A segment primarily responsible for supporting customers using reciprocating engines, turbines and related services across industries serving Power Generation, Oil and Gas and Industrial applications, including marine applications and product support of on-highway engines. Responsibilities include business strategy, product design, product management, development and testing, manufacturing, marketing and sales and product support. The product and services portfolio includes turbines, centrifugal gas compressors, and turbine-related services; reciprocating engine-powered generator sets; integrated systems and solutions used in the electric power generation industry; reciprocating engines, drivetrain and integrated systems and solutions for the oil and gas industry; reciprocating engines, drivetrain and integrated systems and solutions supplied to the industrial industry as well as Caterpillar machines; and electrified powertrain and zero-emission power sources and service solutions. Responsibilities also include the remanufacturing of Caterpillar reciprocating engines and engine and machine components and remanufacturing services for other companies. Inter-segment sales are a source of revenue for this segment.

Construction Industries: A segment primarily responsible for supporting customers using machinery in infrastructure and building construction applications. Responsibilities include business strategy, product design, product management and development, manufacturing, marketing and sales and product support. The product portfolio includes asphalt pavers; backhoe loaders; cold planers; compactors; compact track loaders; forestry machines; material handlers; motor graders; pipelayers; road reclaimers; skid steer loaders; telehandlers; track-type loaders; track-type tractors (small, medium); track excavators (mini, small, medium, large); wheel excavators; wheel loaders (compact, small, medium); and related parts and work tools. Inter-segment sales are a source of revenue for this segment.

Resource Industries: A segment primarily responsible for supporting customers using machinery in mining, heavy construction and quarry and aggregates as well as customers using locomotives and rail-related products and services. Responsibilities include business strategy, product design, product management and development, manufacturing, marketing and sales and product support. The product portfolio includes large track-type tractors; large mining trucks; hard rock vehicles; electric rope shovels; draglines; hydraulic shovels; rotary drills; large wheel loaders; off-highway trucks; articulated trucks; wheel tractor scrapers; wheel dozers; landfill compactors; soil compactors; wide-body trucks; select work tools; machinery components; wear and maintenance components and related parts; diesel-electric, hybrid and battery-electric locomotives and components and other rail-related products and services, including remanufacturing and leasing. In addition, Resource Industries sells technology products and services to provide customers fleet management, equipment management analytics, autonomous machine capabilities, safety services and mining performance solutions. Resource Industries also manages areas that provide services to other parts of the company, including strategic procurement, lean center of excellence, integrated component design and manufacturing and research and development for hydraulic systems and cabs. Inter-segment sales are a source of revenue for this segment.

Financial Products Segment: Provides financing alternatives to customers and dealers around the world for Caterpillar products and services, as well as financing for power generation facilities that incorporate Caterpillar products. Financing plans include operating and finance leases, revolving charge accounts, installment sale contracts, repair/rebuild financing, working capital loans and wholesale financing plans. The segment also provides insurance and risk management products and services that help customers and dealers manage their business risk. Insurance and risk management products offered include physical damage insurance, inventory protection plans, extended service coverage and maintenance plans for machines and engines, and dealer property and casualty insurance. The various forms of financing, insurance and risk management products offered to customers and dealers help support the purchase and lease of Caterpillar equipment. The segment also earns revenues from Machinery, Power & Energy, but the related costs are not allocated to operating segments. Financial Products’ segment profit is determined on a pretax basis and includes other income/expense items.

All Other Segment: Primarily includes activities such as: business strategy; product management and development; parts distribution; integrated logistics solutions; electronics and control systems; distribution services responsible for dealer development and administration, including a wholly owned dealer in Japan; dealer portfolio management and ensuring the most efficient and effective distribution of machines, engines and parts; brand management and marketing strategy; research and development for automation, electronics and software for machines and engines and digital investments for new customer and dealer solutions that integrate data analytics with state-of-the-art digital technologies while transforming the buying experience. Results for the All Other Segment are included as a reconciling item between reportable segments and consolidated external reporting.

C. Segment measurement and reconciliations

We determine the segment profit of Power & Energy, Construction Industries, Resource Industries, and our All Other Segment on a pretax basis and exclude most interest expense and certain other income (expense) items. We determine Financial Products Segment profit on a pretax basis and include other income (expense) items.

Our CODM evaluates the operating performance of the segments using segment profit as it provides insight into the financial health of each segment. The CODM reviews this metric regularly to compare the profitability of segments, identify trends, and evaluate which segments require additional resources or strategic adjustments. The CODM uses segment profit to support the allocation of resources predominantly in the annual budget and forecasting process. Additionally, the CODM monitors forecast-to-actual variances, focusing on areas where performance deviates from expectations, when evaluating the performance of each segment and making decisions about allocating capital and other resources to each segment.

There are several methodology differences between our segment reporting and our external reporting. The following is a list of the more significant methodology differences:

•For Power & Energy, Construction Industries, Resource Industries, and our All Other Segment net assets generally include inventories, receivables, property, plant and equipment, goodwill, intangibles, accounts payable and customer advances. We generally manage at the corporate level liabilities other than accounts payable and customer advances, and we do not include these in segment operations. Financial Products Segment assets generally include all categories of assets.

•We value segment inventories and cost of sales using a current cost methodology.

•We amortize goodwill allocated to segments using a fixed amount based on a 20-year useful life. This methodology difference only impacts segment assets. We do not include goodwill amortization expense in segment profit. In addition, we have allocated to segments only a portion of goodwill for certain acquisitions made in 2011 or later.

•We generally manage currency exposures for operating segments, other than Financial Products, at the corporate level and do not include in segment profit or segment assets the effects of changes in exchange rates on results of operations and financial position within the year. We report the net difference created in the translation of revenues and costs between exchange rates used for U.S. GAAP reporting and exchange rates used for segment reporting as a methodology difference.

•We do not include stock-based compensation expense in segment profit.

•Postretirement benefit expenses are split; segments are generally responsible for service costs, with the remaining elements of net periodic benefit cost included as a methodology difference.

Reconciling items are created based on accounting differences between segment reporting and our consolidated external reporting. Please refer to pages 28-30 for financial information regarding significant reconciling items. Most of our reconciling items are self-explanatory given the above explanations. For the reconciliation of profit, we have grouped the reconciling items as follows:

•Corporate costs: These costs are related to corporate requirements primarily for compliance and legal functions for the benefit of the entire organization.

•Restructuring income/costs: May include costs for employee separation, long-lived asset impairments, contract terminations and (gains)/losses on divestitures. These costs are included in Other operating (income) expenses except for defined-benefit plan curtailment losses and special termination benefits, which are included in Other income (expense). Restructuring costs also include other exit-related costs, which may consist of accelerated depreciation, inventory write-downs, building demolition, equipment relocation and project management costs and LIFO inventory decrement benefits from inventory liquidations at closed facilities, all of which are primarily included in Cost of goods sold. See Note 20 for more information.

•Methodology differences: See previous discussion of significant accounting differences between segment reporting and consolidated external reporting.

•Timing: Timing differences in the recognition of costs between segment reporting and consolidated external reporting. For example, we report certain costs on the cash basis for segment reporting and the accrual basis for consolidated external reporting.

Allowance for Credit Losses

Allowance for credit losses

Portfolio segments

A portfolio segment is the level at which Cat Financial develops a systematic methodology for determining its allowance for credit losses. Cat Financial's portfolio segments and related methods for estimating expected credit losses are as follows:

Customer

Cat Financial provides loans and finance leases to end-user customers primarily for the purpose of financing new and used Caterpillar machinery, engines and equipment for commercial use. Cat Financial also provides financing for power generation facilities that incorporate Caterpillar products. The average original term of Cat Financial's customer finance receivables portfolio was approximately 51 months with an average remaining term of approximately 28 months as of March 31, 2026.

Cat Financial typically maintains a security interest in financed equipment and generally requires physical damage insurance coverage on the financed equipment, both of which provide Cat Financial with certain rights and protections. If Cat Financial's collection efforts fail to bring a defaulted account current, Cat Financial generally can repossess the financed equipment, after satisfying local legal requirements, and sell it within the Caterpillar dealer network or through third-party auctions.

Cat Financial estimates the allowance for credit losses related to its customer finance receivables based on loss forecast models utilizing probabilities of default and the estimated loss given default based on past loss experience adjusted for current conditions and reasonable and supportable forecasts capturing country and industry-specific economic factors.

During the three months ended March 31, 2026, Cat Financial's forecasts reflected a continuation of global market uncertainty and actions by global central banks aimed at balancing economic growth and managing inflation. Cat Financial believes the economic forecasts employed represent reasonable and supportable forecasts, followed by a reversion to long-term trends.

Dealer

Cat Financial provides financing to Caterpillar dealers on a secured and unsecured basis in the form of wholesale financing plans and retail loans. Cat Financial's wholesale financing plans provide financing to dealers for their new Caterpillar equipment inventory and rental fleets. The retail loans to Caterpillar dealers are primarily for working capital.

Cat Financial estimates the allowance for credit losses for dealer finance receivables based on historical loss rates with consideration of current economic conditions and reasonable and supportable forecasts.

In general, Cat Financial's Dealer portfolio segment has not historically experienced large increases or decreases in credit losses based on changes in economic conditions due to its close working relationships with the dealers and their financial strength. Therefore, Cat Financial made no adjustments to historical loss rates during the three months ended March 31, 2026.

Classes of finance receivables

Cat Financial further evaluates portfolio segments by the class of finance receivables, which is defined as a level of information (below a portfolio segment) in which the finance receivables have the same initial measurement attribute and a similar method for assessing and monitoring credit risk. Cat Financial's classes, which align with management reporting for credit losses, are as follows:

•North America - Finance receivables originated in the United States and Canada.

•EAME - Finance receivables originated in Europe, Africa, the Middle East and Eurasia.

•Asia/Pacific - Finance receivables originated in Australia, New Zealand, China, Japan, Southeast Asia and India.

•Latin America - Finance receivables originated in Mexico and Central and South American countries.

•Mining - Finance receivables originated worldwide related to large mining customers.

•Power - Finance receivables originated worldwide related to large power customers of Caterpillar electrical power generation, gas compression and co-generation systems and non-Caterpillar equipment that is powered by these systems.

Receivable balances, including accrued interest, are written off against the allowance for credit losses when, in the judgment of management, they are considered uncollectible (generally upon repossession of the collateral). Generally, the amount of the write-off is determined by comparing the fair value of the collateral, less cost to sell, to the amortized cost of the receivable. Subsequent recoveries, if any, are credited to the allowance for credit losses when received.

Fair Value Measurement

Fair value measurements

The guidance on fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. This guidance also specifies a fair value hierarchy based upon the observability of inputs used in valuation techniques. Observable inputs (highest level) reflect market data obtained from independent sources, while unobservable inputs (lowest level) reflect internally developed market assumptions. In accordance with this guidance, fair value measurements are classified under the following hierarchy:

•Level 1 — Quoted prices for identical instruments in active markets.

•Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable in active markets.

•Level 3 — Model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable.

When available, we use quoted market prices to determine fair value, and we classify such measurements within Level 1. In some cases where market prices are not available, we make use of observable market based inputs to calculate fair value, in which case the measurements are classified within Level 2. If quoted or observable market prices are not available, fair value is based upon valuations in which one or more significant inputs are unobservable, including internally developed models that use, where possible, current market-based parameters such as interest rates, yield curves and currency rates. These measurements are classified within Level 3.

We classify fair value measurements according to the lowest level input or value-driver that is significant to the valuation. We may therefore classify a measurement within Level 3 even though there may be significant inputs that are readily observable.

Fair value measurement includes the consideration of nonperformance risk. Nonperformance risk refers to the risk that an obligation (either by a counterparty or Caterpillar) will not be fulfilled. For financial assets traded in an active market (Level 1 and certain Level 2), the nonperformance risk is included in the market price. For certain other financial assets and liabilities (certain Level 2 and Level 3), our fair value calculations have been adjusted accordingly.

Investments in debt and equity securities

We have investments in certain debt and equity securities that are recorded at fair value. Fair values for our U.S. treasury bonds and large capitalization value and smaller company growth equity securities are based upon valuations for identical instruments in active markets. Fair values for other government debt securities, corporate debt securities and mortgage-backed debt securities are based upon models that take into consideration such market-based factors as recent sales, risk-free yield curves and prices of similarly rated bonds.

In addition, Insurance Services has an equity investment in a real estate investment trust (REIT) which is recorded at fair value based on the net asset value (NAV) of the investment and is not classified within the fair value hierarchy.

See Note 8 for additional information on our investments in debt and equity securities.

Derivative financial instruments

The fair value of interest rate contracts is primarily based on a standard industry accepted valuation model that utilizes the appropriate market-based forward swap curves and zero-coupon interest rates to determine discounted cash flows. The fair value of foreign currency and commodity forward, option and cross currency contracts is based on standard industry accepted valuation models that discount cash flows resulting from the differential between the contract price and the market-based forward rate. The fair value of total return swap contracts is primarily based on valuing the underlying securities or funds using pricing by industry providers and the average Secured Overnight Financing Rate (SOFR) plus a spread.

In addition to the methods and assumptions we use to record the fair value of financial instruments as discussed in the Fair value measurements section above, we use the following methods and assumptions to estimate the fair value of our financial instruments:

Cash and cash equivalents

Carrying amount approximates fair value. We classify cash and cash equivalents as Level 1. See Consolidated Statement of Financial Position.

Restricted cash and short-term investments

Carrying amount approximates fair value. We include restricted cash and short-term investments in Prepaid expenses and other current assets in the Consolidated Statement of Financial Position. We classify these instruments as Level 1. See Note 8 for additional information.

Finance receivables

We estimate fair value by discounting the future cash flows using current rates, representative of receivables with similar remaining maturities.

Wholesale inventory receivables

We estimate fair value by discounting the future cash flows using current rates, representative of receivables with similar remaining maturities.

Short-term borrowings

Carrying amount approximates fair value. We classify short-term borrowings as Level 1. See Consolidated Statement of Financial Position.

Long-term debt

We estimate fair value for fixed and floating rate debt based on quoted market prices.

Restructuring Costs

Our accounting for employee separations is dependent upon how the particular program is designed. For voluntary programs, we recognize eligible separation costs at the time of employee acceptance unless the acceptance requires explicit approval by the company. For involuntary programs, we recognize eligible costs when management has approved the program, the affected employees have been properly notified and the costs are estimable.
