Description of Business
UL Solutions Inc. (together with its consolidated subsidiaries, “UL Solutions” and the “Company”) is a global safety science leader that provides independent third-party testing, inspection and certification services and related software and advisory offerings. Underwriters Laboratories Inc. (“UL Research Institutes”) is the sole member of ULSE Inc. (“UL Standards & Engagement”), which controls the majority of the voting power of the Company’s common stock.
The Company serves its customers, manages the business and reports its financial results through three segments: Industrial, Consumer, and Software and Advisory (“S&A”). The Company generates revenue in these segments and the following service categories: Certification Testing; Ongoing Certification Services; Non-certification Testing and Other Services; and Software.
Effective beginning in the first quarter of 2026, the Company reorganized its segments to be consistent with how the Chief Executive Officer will evaluate business performance and allocate resources. The amounts included within these financial statements reflect the Company’s segment structure that existed through the end of 2025. Refer to Note 22, “Subsequent Events” for further details.
Public Offerings
On April 16, 2024, the Company completed its initial public offering of an aggregate of 38,870,000 shares of Class A common stock (the “IPO”) by UL Standards & Engagement at a price to the public of $28.00 per share. On September 9, 2024, the Company completed a follow-on public offering of an aggregate of 23,000,000 shares of Class A common stock by UL Standards & Engagement at a price to the public of $49.00 per share. On December 5, 2025, the Company completed a follow-on public offering of an aggregate of 14,375,000 shares of Class A common stock by UL Standards & Engagement at a price to the public of $78.00 per share. The Company did not receive any proceeds from these offerings. Refer to Note 15, “Common Stock” for further information.
Basis of Presentation
The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and variable interest entities for which the Company has determined it is the primary beneficiary. All intercompany accounts and transactions have been eliminated. The Company accounts for investments in businesses using the equity method when it has significant influence but not control (generally between 20% and 50% ownership) and is not the primary beneficiary. The significant accounting policies, as summarized below, conform to accounting principles generally accepted in the United States of America (“US GAAP”). The Company has reclassified certain amounts in prior period financial statements to conform to the current period’s presentation.
Use of Estimates
The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the 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. Estimates are inherently uncertain and actual results could differ materially from estimated amounts. Estimates are used for, but are not limited to, contractual revenue recognized, future cash flows associated with impairment testing for goodwill, certain assumptions related to pension and postretirement benefits and income taxes. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Cash and Cash Equivalents
Cash and cash equivalents include investments purchased with original maturities of three months or less.
Accounts Receivable and Contract Assets
Accounts receivable consists of trade receivables billed and currently due from customers as well as amounts currently due from other external parties. Contract assets represent revenues for projects that have been recognized for accounting purposes, but not yet billed to customers. The Company’s standard payment terms are due upon receipt of the invoice, except for certain customers, which may be required to make advance payments.
The Company extends credit to customers in the normal course of business, generally not longer than 90 days, and maintains an allowance for credit losses. The allowance is an estimate based on historical collection experience, current and future economic and market conditions and a review of the current status of each customer’s trade accounts receivable. Management evaluates the aging of the accounts receivable balances and the financial condition of its customers and all other forward-looking information that is reasonably available to estimate the amount of accounts receivable that may not be collected in the future and records the appropriate provision. Account balances are written off against the allowance when it is determined the accounts receivable will not be recovered.

Concentration of Credit Risk
Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents, accounts receivable and contract assets. Credit risk represents the accounting loss that would be recognized at the reporting date if counterparties failed to perform as contracted. The Company believes the likelihood of incurring material losses due to concentration of credit risk is minimal. The Company actively limits its exposure to credit risk by maintaining cash deposits with major financial institutions as counterparties and by maintaining accounts receivable with a large number of customers in diverse industries and geographies in addition to establishing reasonable credit approvals and limits.
Property, Plant and Equipment
Property, plant and equipment are stated at cost, net of accumulated depreciation. Major replacements and improvements are capitalized, while maintenance and repairs, which do not improve or extend the life of the respective assets, are expensed as incurred. Gains and losses resulting from sales and retirements are included within operating income.
Depreciation is computed using the straight–line method over the estimated useful life of the asset as follows:
Land improvements15 years
Building and building improvements
15 - 50 years
Leasehold improvementsShorter of expected useful life or lease term
Machinery, equipment and office furniture
3 - 15 years
Goodwill
The Company accounts for business combinations using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, which requires an allocation of the purchase consideration transferred to the identifiable assets and liabilities based on the estimated fair values as of the acquisition date. Goodwill represents the excess of the purchase price of an acquired entity over the fair value of net assets acquired. Goodwill is tested for impairment annually in the fourth quarter, or more frequently if an event occurs or conditions change that would indicate it is more likely than not that the fair value of a reporting unit is below its carrying amount. The Company’s reporting units have been identified as one level below its operating segments. The goodwill impairment testing is performed by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value.
To evaluate the recoverability of a reporting unit’s goodwill the Company has the option to first perform a qualitative analysis. If the qualitative analysis indicates it is more likely than not that the fair value of a reporting unit is below its carrying amount, the Company performs a quantitative impairment assessment for that reporting unit.
The Company’s quantitative assessment consists of a fair value calculation for each reporting unit that combines an income approach and a market approach, using an equal weighting. The quantitative assessment requires the application of a number of significant assumptions which are further described below, including estimated future cash flows of the reporting unit, discount rates, and market multiples.
The fair value using the income approach is determined based on the present value of estimated future cash flows of the reporting unit, discounted at an appropriate risk‑adjusted rate. The Company uses its internally developed long-range plans to estimate future cash flows, which include an estimate of long‑term future growth rates based on its most recent views of the long‑term outlook for each reporting unit. Development of the Company’s long-range plans includes consideration of current and projected levels of income for the reporting unit based on management’s plans for that business, business trends, market and economic conditions, as well as other relevant factors. The discount rate is based on the weighted average cost of capital for the reporting unit. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the respective businesses and in the Company’s long-range plans.
The fair value using the market approach is derived from market multiples using comparable publicly traded companies for a group of benchmark companies. The selection of comparable businesses is based on the markets in which the reporting units operate giving consideration to risk profiles, size, geography and diversity of products and services.
During the three months ended September 30, 2023, the Company identified a triggering event and performed a quantitative impairment assessment for a reporting unit in the Consumer segment, which resulted in a pre-tax impairment charge of $37 million. Refer to Note 9, “Goodwill” for further details. The Company did not recognize any impairments of goodwill for the years ended December 31, 2025 or 2024.
Intangible and Other Long-lived Assets
The Company amortizes finite-lived intangible assets using the straight-line method over their estimated economic useful lives, which range from three to twenty years. The Company reviews long-lived assets, including property, plant and equipment, capitalized software and intangible assets with finite lives for impairment whenever an event occurs or conditions change that indicate the carrying amount of the asset group may not be recoverable. When such events occur, the Company performs a recoverability test by comparing the projected undiscounted cash flows of the asset group to the carrying amount. If this comparison indicates that there is a potential impairment, the asset group’s fair value is determined based on the present value of its estimated future cash flows, discounted at an appropriate risk-adjusted rate. An impairment charge is recorded for the amount by which the carrying amount of the asset group exceeds its fair value. The Company did not recognize any material impairments of intangible or other long-lived assets for the years ended December 31, 2025, 2024 or 2023.
Leases
The Company determines if an arrangement is a lease at inception and reassesses that conclusion if the contract is modified. The Company evaluates whether the arrangement conveys the right to control the use of an identified asset for a period of time in exchange for consideration in order to determine if the contract is or contains a lease. The right to control the use of an identified asset includes the right to obtain substantially all of the economic benefits from use of the asset and the right to direct the use of the asset.
The Company’s classes of leased assets include real estate, vehicles, and equipment. When it is reasonably certain that an option to extend or terminate a lease will be exercised, the Company includes the option in the recognition of right-of-use (“ROU”) assets and lease liabilities. The Company does not recognize ROU assets or lease liabilities for leases with a term of twelve months or less. The Company accounts for lease and non-lease components as a single component for all asset classes.
ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at lease commencement and measured based on the present value of lease payments over the lease term. Variable lease payments, which may include certain non-lease costs such as real estate taxes, common area maintenance and insurance, are recognized as incurred and are not presented as part of the ROU asset or lease liability, unless such payments are fixed or in-substance
fixed, which may include payments that depend on an underlying index or rate. Operating lease cost is recognized on a straight-line basis over the lease term. The Company does not have material finance leases.
The Company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. The Company’s incremental borrowing rate is based on its estimated rate of interest for a collateralized borrowing over a similar term as the lease payments. The same process is followed for any new leases at their commencement dates or modification to existing leases that require remeasurement.
Capitalized Software
Costs related to software acquired or developed solely for the Company’s internal use, as well as costs to develop cloud-based applications provided to customers as a service (i.e. SaaS arrangements) are capitalized in accordance with ASC Topic 350-40, Internal-use Software (“ASC 350-40”). Certain costs incurred after the completion of the preliminary project stage and after management, with the relevant authority, has authorized and committed funds to the software project, and it is probable that the project will be completed and the software will be used to perform the function intended, are capitalized. For development costs capitalized under the requirements of ASC 350-40, amortization begins when each software module is ready for its intended use. Costs are amortized on a straight-line basis over the estimated useful life of the software (generally three to five years). Costs related to preliminary project activities and post implementation activities are expensed as incurred. Additions to capitalized software are reported within capital expenditures in the Consolidated Statements of Cash Flows.
The Company capitalizes certain implementation costs related to cloud computing service arrangements with third-party vendors that are incurred during the application development stage. Subsequently, the costs are amortized on a straight-line basis over the non-cancelable term of the hosting agreement plus any reasonably certain renewal periods. Capitalized implementation costs are included as a component of other assets on the Consolidated Balance Sheets and amortization is included as an operating expense in the Consolidated Statements of Operations. Additions to capitalized cloud implementation costs are reported within operating activities in the Consolidated Statements of Cash Flows.
Costs related to software to be sold, leased or otherwise marketed are expensed as incurred until technological feasibility has been established in accordance with ASC Topic 985-20, Costs of Software to be Sold, Leased, or Marketed. Certain costs incurred subsequent to establishing technological feasibility are capitalized up until the software is available for general release, and are amortized on a straight-line basis over the estimated useful life of the software (generally three to five years).
Amortization expense of capitalized software costs totaled $65 million, $59 million and $51 million for the years ended December 31, 2025, 2024 and 2023, respectively.
Accounts Payable and Contract Liabilities
Accounts payable consists of trade payables currently due to vendors as well as amounts currently due to other external parties. Contract liabilities include payments received in advance of performance under the contract and are subsequently reduced when the associated revenue is recognized for the respective contract. Amounts initially recorded as contract liabilities are recognized as revenue in accordance with the Company’s revenue recognition policy.
Fair Value
The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short maturities. For fair value of the Company’s debt see Note 6.
ASC Topic 820, Fair Value Measurement (“ASC 820”), defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:
•Level 1 observable inputs such as quoted prices in active markets;
•Level 2 inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
•Level 3 unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.
ASC 820 requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. The Company does not have any assets or liabilities measured at fair value on a recurring basis that are Level 3, except for certain pension assets discussed in Note 11. The Company did not have any transfers between fair value levels during the years ended December 31, 2025 and 2024.
Revenue Recognition
The Company recognizes revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), when its customer obtains control of promised goods or services, or as the Company renders services, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods and services. For each arrangement the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligation(s) in the contract, (3) determine the transaction price, (4) if applicable, allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the Company satisfies a performance obligation.
The Company’s contracts with customers generally relate to services that are distinct and are accounted for separately. Those goods and services that are determined to be separate performance obligations are treated as separate units of account and each separate performance obligations has its own stand-alone selling price, which is the price at which an entity would sell a promised good or service separately to a similar customer in similar circumstances. The stand-alone selling price is determined using an established list price for the specific service and geographical region, or through a needs-based assessment. If a needs-based assessment approach is used, the stand-alone selling price is estimated by multiplying the expected labor hours by a labor rate. The labor rate is determined by considering the cost of labor, other miscellaneous costs (e.g., overhead) and applying a margin. The labor rate may be adjusted for geographic differences and other items as determined necessary, and is reviewed on a periodic basis for appropriateness.
The majority of the Company’s revenue from contracts with customers represents revenue from services recognized over time as performance obligations are satisfied. Revenue from over-time arrangements is recognized either on a straight line basis as the service is provided to the customer, or using an input method, which requires the Company to make estimates, in particular in relation to measuring progress towards completion. For arrangements recognized over time using an input method, progress towards completion is based on the relationship between the time elapsed of each project phase relative to the expected duration of that phase. The portion of a project’s revenue to be recognized is determined based on the time elapsed between the start-date of each project phase relative to its estimated duration. The start-date of each phase is based on the date that work begins on the phase and the estimated duration is determined using an analysis of historical data from similar projects. Management applies judgment in determining the expected duration of each phase. The portion of a project’s revenue estimated as earned, but not yet completed, and recognized as revenue, is included in contract assets or as a reduction to contract liabilities.
The Company’s cost to obtain a contract is generally commission paid to sales personnel for the sale of services. Management determined that the amortization period of the commission costs would be one year or less and therefore has elected the practical expedient to expense these costs as incurred. As a result, the costs to obtain a contract are expensed as incurred.
The Company typically does not incur costs to fulfill contracts which would meet the capitalization criteria and therefore these costs are typically expensed as incurred. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.
Refer to Note 3, “Revenue” for additional information.
Cost of Revenue
Cost of revenue includes employee compensation consisting of salaries, incentives, stock-based compensation and other benefits for employees directly attributable to revenue generation across each of the Company’s four major service categories. In addition, cost of revenue includes services and materials expenses including facility related costs for laboratories and other buildings where testing and inspection services are performed, customer-related travel costs, expenses related to third party contractors or third party facilities and consumable materials and supplies used in testing and inspection and other costs associated with generating revenue. Cost of revenue also includes depreciation on equipment used in testing and amortization of capitalized software sold to customers.
Selling, General and Administrative Expenses
Selling, general and administrative expenses include employee compensation consisting of salaries, incentives, stock-based compensation and other benefits for sales and indirect administrative functions such as executive, finance, legal, human resources and information technology, not included within cost of revenue. In addition, selling, general and administrative expenses include services and materials expenses including third party consultancy costs, facility costs, internal research and development costs as well as legal and accounting fees, travel, marketing, bad debt and non‑chargeable materials and supplies. Selling, general and administrative expenses also include depreciation and amortization.
Foreign Currency
The functional currency of certain of the Company’s foreign affiliates is the local currency. Assets and liabilities of international subsidiaries have been translated into U.S. dollars at the balance sheet date, and income and expense items have been translated using monthly average exchange rates for the period. The resulting currency translation adjustments have been recorded as a separate component of other comprehensive income (loss). The Company revalues assets and liabilities entered in foreign currency at the balance sheet date and the resulting unrealized gain (loss) is recorded as other (expense) income, net in the Consolidated Statements of Operations.
Beginning in the second quarter of 2023, realized gains (losses) on foreign currency transactions, which were previously recorded within selling, general and administrative expenses, are recorded within other (expense) income, net in the Consolidated Statements of Operations. Losses on foreign currency transactions recorded within selling, general and administrative expenses were immaterial in 2023.
Stock-based Compensation
The Company maintains long-term incentive plans under which equity awards are available to be issued to certain employees, officers and directors. Stock-based compensation expense, measured as the fair value of an award on the date of grant, is recognized ratably over the requisite service period, which is generally equal to the vesting period of the respective award, however, it may be impacted by certain factors including the employee’s death, disability or retirement. Compensation expense related to performance share units is adjusted each reporting period based on the probable outcome of the performance conditions applicable to each grant.
The fair value of restricted stock units and performance share units is determined using the closing price of the Company’s stock on the date of grant. The fair value of each stock option is measured on the date of grant using a Black-Scholes-Merton option-pricing model that uses various assumptions including expected stock price volatility, expected dividend yield, the risk-free interest rate, and expected term of the award.
Restructuring
Restructuring expenses consist of employee-separation costs, including severance and other benefits calculated based on long-standing benefit practices and local statutory requirements. In most jurisdictions, the Company has ongoing benefit arrangements under which the Company records estimated severance and other termination benefits when such costs are deemed probable and estimable, approved by management, and if actions required to complete the termination plan indicate it is unlikely that significant changes to the plan will be made or the plan will be withdrawn. Severance and other termination benefits for which there is not an ongoing benefit arrangement are recorded when management has committed to the plan and the benefit arrangement is communicated to the affected employees. Other costs may include facility exit costs related to accelerated right-of-use asset amortization, gains and losses on early lease terminations, and other exit costs for leases which will be abandoned, as well as professional services costs related to restructuring activities.
Other (Expense) Income, net
Other (expense) income, net consists primarily of non-operating gains and losses, including gains and losses related to foreign exchange transactions and the revaluation performed on designated balance sheet accounts, interest income, gains and losses on equity investments, non-operating pension and postretirement benefit expenses and gains on divestitures.
Interest Expense
Interest expense consists primarily of interest expense on the Company’s debt obligations.
Income Taxes
The Company recognizes income taxes based on amounts refundable or payable for the current year and records deferred tax assets or liabilities for temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, net operating loss carryforwards and tax credit carryforwards. Deferred tax assets and liabilities are measured using current enacted tax rates expected to apply to taxable income in the years in which temporary differences are expected to reverse. Inherent in determining the annual tax rate are judgments regarding business plans, planning opportunities and expectations about future outcomes. Realization of certain deferred tax assets, primarily net operating loss and other carryforwards, is dependent upon generating sufficient taxable income in the appropriate jurisdiction prior to the expiration of the carryforward periods. The Company has classified all deferred tax assets and liabilities, along with any related valuation allowances, as net non-current on the Consolidated Balance Sheets. Deferred tax expense or benefit is the result of changes in the deferred tax asset or liability.
The Company records valuation allowances to reduce deferred tax assets to reflect the amount that is more-likely-than-not to be realized. When assessing the need for valuation allowances, the Company considers all available evidence, including three years of cumulative income/(loss) before taxes, expected future taxable income and ongoing prudent and feasible tax planning strategies. Should a change in circumstances lead to a change in judgment about the realizable value of deferred tax assets in future years, the Company would adjust related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income.
For uncertain tax positions related to exposures associated with various tax filing positions, the Company recognizes a tax benefit only if it is more‑likely‑than‑not that the tax position will be sustained upon examination by the relevant taxing authorities, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that is more‑likely‑than‑not to be realized upon settlement. The Company adjusts its liability for unrecognized tax benefits in the period they are settled, the statute of limitations expires, or when new information becomes available. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense.
The Company has generated income in certain foreign jurisdictions that may be subject to additional foreign withholding taxes and U.S. state income taxes, if repatriated. The Company regularly reviews its plans for reinvestment or repatriation of unremitted foreign earnings and has recorded deferred tax liabilities on certain foreign subsidiaries’ unremitted earnings that are not considered permanently reinvested. The Company’s assertion on indefinite reinvestment of foreign earnings is based upon assumptions of future liquidity needs of the business and cash flow projections of its subsidiaries.
The accounting policy of the Company is to record U.S. tax on Global Intangible Low-Taxed Income in the provision for income taxes in the year it is incurred.
Recently Issued Accounting Standards – Adopted
Effective for the year ended December 31, 2025, the Company adopted Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. The ASU was adopted prospectively and did not impact the Company’s financial condition, results of operations or cash flows. Refer to Note 12, “Income Taxes” for further information.
Recently Issued Accounting Standards – Not Adopted
In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures, which is intended to improve disclosures about a public business entity’s expense and provide more detailed information to investors about the types of expenses in commonly presented expense captions. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, on either a prospective or retrospective basis, with early adoption permitted. The Company expects to adopt the new annual disclosure as required for the year ended December 31, 2027 and the interim disclosures as required beginning with the first quarter of 2028. The application of this new guidance is not expected to have a material impact on the Company’s consolidated financial condition, results of operations, or cash flows, as the guidance pertains to disclosure only.

Description of Major Service Categories
Certification Testing
The Company evaluates products, components and systems according to global or regional regulatory requirements and other design and performance specifications. Select certification testing services include testing to global or regional standards, engineering evaluation and project review and functional safety testing of embedded software. Certification testing services generally align with the new product development cycle and help customers mitigate risk, demonstrate compliance with regulatory requirements and deliver confidence to businesses and consumers, resulting in demand for ongoing certification services. As a result of the certification process, the Company may authorize its customers to use the Company’s certification marks, including the Company’s registered UL-in-a-circle certification mark (the “UL Mark”), on their products, packaging and marketing collateral as part of their manufacturing, distribution and marketing processes to demonstrate to the marketplace that their product has met the applicable requirements. Certification testing services often lead to Ongoing Certification Services to support the continued safety, compliance and performance objectives of the customer.
Contracts are generally structured as fixed payments as the total amount to be charged to the customer does not vary. Revenue from Certification Testing is generally recognized over-time. In these cases, the services create an asset with no alternative use as each of the services are specific to the products and specifications provided by the customer, and the Company has an enforceable right to payment. Revenue is generally recognized based on the relationship between the time elapsed of each project phase relative to the expected duration of that phase, which is considered the most indicative of the Company’s performance to-date under the terms of the contract.
In some instances, revenue from Certification Testing does not meet the over-time criteria and is recognized at a point in time when control is transferred to the customer. Control is transferred to the customer upon the delivery of the test report to the customer. These instances occur when the agreement or the nature of the services causes a lack of right to payment until control transfer.
Ongoing Certification Services
To maintain the right to use the Company’s certification marks, including the UL Mark, and meet certain regulatory requirements, the Company’s customers must meet certain certification program requirements, including mandatory inspection and monitoring by the Company. These requirements, addressed through standard certification and inspection services, are designed to validate the continued compliance of the Company’s customers’ previously certified products, components and systems. Services are delivered through periodic inspections, initial and follow-up audits, sample testing and UL Solutions label usage. The frequency and combination of these services can vary based on product, component or system type, production volume and historical risk-based customer compliance. These ongoing certification services are designed and executed to help the Company’s customers confirm ongoing compliance and to help protect the integrity of the UL Mark. Select services include factory inspection and testing to confirm products that are being produced match the configuration of products that were tested and certified.
Contracts are generally structured as fixed payments as the total amount to be charged to the customer does not vary. In some cases, the customer is charged a usage price based on its total production volume. Revenue from compliance program contracts is recognized over-time on a straight-line basis because the customer receives and consumes the benefit of continued certification as the Company performs services through the periodic verification of the customer’s compliance.
As part of Ongoing Certification Services, customers may order physical labels (recorded in other current assets) that bear the UL Mark to affix to their products to demonstrate to end-customers that the products comply with the certification requirements of the Company. The labels are a separate performance obligation, distinct from the compliance program. Revenue from physical labels is recognized upon shipment, the point in time in which the customer obtains control of the labels.
Non-certification Testing, and Other Services
The Company offers testing services to address performance and other requirements that may not be required by any regulation and may not result in a certification, but are still desired by the Company’s customers to help ensure the safety, performance and reliability of their products. Select services include on-site and remote inspections, audits and field engineering specialty services, testing for energy efficiency, wireless and electromagnetic compatibility, quality, chemical and reliability for customers in medical devices, information technologies, appliances, HVAC and lighting. For retail and consumer customers, the Company offers testing such as color-matching, sensory, emissions and flame resistance. Lastly, the Company offers advisory and technical services to support the Company’s customers in managing their safety, compliance, regulatory risk and sustainability programs.
Contracts are generally structured as fixed payments as the total amount to be charged to the customer does not vary. For services where the customer does not simultaneously receive and consume the benefit of the performance obligation, revenue is recognized upon the delivery of the final deliverables to the customer. For services that create an asset with no alternative use as each of the services are specific to the products and specifications provided by the customer, and the Company has an enforceable right to payment, revenue is generally recognized based on the relationship between the time elapsed of each project phase relative to the expected duration of that phase, which is considered the most indicative of the Company’s performance to date under the terms of the contract. Advisory revenue is generally recognized over time.
In some instances, revenue from non-certification testing does not meet the over-time criteria and is recognized at a point in time when control is transferred to the customer. Control is transferred to the customer upon the delivery of the test report to the customer. These instances occur when the agreement or the nature of the services causes a lack of right to payment until control transfer.
Software
The Company provides software as a service (“SaaS”) and license-based software solutions, including implementation and training services related to software, to enable the Company’s customers to manage complex regulatory requirements, deliver supply chain transparency and operationalize sustainability. The Company’s SaaS and licensed software solutions provide data-driven product stewardship, chemicals management, supply chain insights, environmental, social and governance (“ESG”) data and reporting, environmental, health and safety (“EHS”) training, management and compliance, and additional regulatory driven software solutions.
Contracts are structured as fixed payments as the total amount to be charged to the customer does not vary. The Company generally recognizes revenue from SaaS contracts, which are provided on a subscription basis, ratably over the contract period beginning on the date the service is first made available to the customer. The Company generally recognizes revenue from on-premise software at a point in time when it is made available to the customer. The revenue from implementation services, post-contract customer support services, and other customer support services is recognized over the service period as the customer benefits from the services as they are performed.
Contract Balances
Gross contract liabilities for services totaled $130 million and $123 million as of December 31, 2025 and 2024, respectively, which are reduced by previously recognized revenue of $32 million and $31 million as of December 31, 2025 and 2024, respectively. In addition, contract liabilities include amounts collected for annual fees as well as fees collected on software license arrangements that are earned over the term of the arrangement. Contract liabilities for these services totaled $75 million and $70 million as of December 31, 2025 and 2024, respectively.
The revenue recognized during the year ended December 31, 2025, that was included in contract liabilities at December 31, 2024, amounted to $124 million. The revenue recognized during the year ended December 31, 2024, that was included in contract liabilities at December 31, 2023, amounted to $119 million.
Remaining Performance Obligations
At December 31, 2025, the Company estimates that $205 million in revenue is expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. The Company expects to recognize approximately 65% of its unsatisfied (or partially unsatisfied) performance obligations as revenue in the subsequent 12 months, with the remaining balance to be recognized thereafter.
Remaining consideration from contracts with customers is included in the amount presented above and includes contracts with multiple performance obligations and multi-year agreements, which are typically recognized as the performance obligation is satisfied.

Acquisitions
In July 2024, the Company acquired 100% of the outstanding stock of TesTneT Engineering GmbH (together with its subsidiaries, “TesTneT”) for approximately $19 million in cash consideration (as adjusted for customary post-closing adjustments). TesTneT is a Germany-based company that provides testing services for various hydrogen storage systems, refueling stations and their components. Goodwill of $14 million represents anticipated future revenue growth and margin expansion opportunities from new customers and has been included within the Company’s Industrial segment. Goodwill related to this acquisition is not deductible for income tax purposes.
In May 2024, the Company acquired 100% of the outstanding stock of Batterielngenieure GmbH (together with its subsidiaries, “Batterielngenieure”) for approximately $12 million in cash consideration (as adjusted for customary post-closing adjustments). Batterielngenieure is a Germany-based battery testing company that was, at the time of acquisition, in the process of building a laboratory in Aachen, Germany to replace the leased facility it was using and to add testing and simulation capacity. The purchase price primarily related to property, plant and equipment of $9 million and goodwill of $8 million. Goodwill represents anticipated future revenue growth and margin expansion opportunities from new customers and has been included within the Company’s Industrial segment. Goodwill related to this acquisition is not deductible for income tax purposes.
Aggregate acquisition-related costs associated with business combinations are not material for the years ended December 31, 2025, 2024, and 2023 and are included in selling, general and administrative expenses in the Company’s Consolidated Statements of Operations as incurred.
Divestiture
In May 2024, the Company completed the sale of its payments testing business in the Industrial segment to an affiliate of Gallant Capital Partners, a California-based private equity firm, for a base price of $29 million in cash (as adjusted for customary post-closing adjustments) with the potential for additional cash consideration if certain earn-out provisions are met. The divestiture resulted in a pre-tax gain on sale of $24 million, which was recorded within other (expense) income, net in the Company’s Consolidated Statements of Operations.

Equity Investments in Non-consolidated Affiliates
The Company holds investments in equity securities of various companies which are accounted for using the equity method when the Company has the ability to exercise significant influence, but not control, over the investee. The carrying amount of these investments was $23 million and $22 million at December 31, 2025 and 2024, respectively, and includes approximately 28% of the registered share capital of DQS Holding GmbH (“DQS”), a global management system assessment company headquartered in Germany. The carrying amount of the Company’s investment in DQS was $22 million and $21 million for the years ended December 31, 2025 and 2024, respectively, and is included within other assets in the Company’s Consolidated Balance Sheets.
The Company holds investments in equity securities of various companies, certain of which comprise less than 10% of the applicable company’s outstanding equity securities and are included within other assets in the Company’s Consolidated Balance Sheets. The Company accounts for these investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The carrying amount of these investments was $33 million and $36 million at December 31, 2025 and 2024, respectively. As of December 31, 2025, the Company had recorded cumulative downward adjustments, including impairments, of $15 million and cumulative upward adjustments of $30 million for these investments within other (expense) income, net.
Variable Interest Investment
The Company, via its wholly owned subsidiary UL LLC, owns 70% of the issued and outstanding equity interests of UL-CCIC Company Limited (“UL-CCIC”), an entity formed under the laws of the People’s Republic of China (“P.R.C”). The remaining 30% equity interest is owned by China Certification & Inspection (Group) Co., Ltd. (“CCIC”), a Chinese state-owned enterprise. UL-CCIC offers product safety testing services enabling its customers to access North American and other international markets, electromagnetic compatibility and commercial inspection and testing services. UL-CCIC provides local voluntary certification schemes to help their customers differentiate their products within the China market. UL-CCIC also offers China Compulsory Certification (“CCC”) testing services under some product categories, which is approved by the Certification and Accreditation Administration P.R.C. and market access agency services to manufacturers to help them obtain the CCC mark.
UL-CCIC is governed by an agreement first entered into on June 26, 2002, and has been amended from time to time. UL-CCIC was established with an initial duration of 10 years, starting from the date that it obtained its business license. This duration has been subsequently extended twice and currently expires in January 2033 pursuant to the amended and restated agreement the Company entered into with CCIC on October 28, 2022.
The board of directors of UL-CCIC consists of seven directors, with four appointed by UL Solutions and three by CCIC. The chair of the UL-CCIC board of directors is appointed by UL Solutions and the vice chair by CCIC. UL-CCIC has a general manager, who is in charge of the day-to-day management of UL-CCIC and reports to the UL-CCIC board of directors. UL Solutions has the exclusive right to nominate the general manager and CCIC has the exclusive right to nominate the deputy general manager.
The Company determined that it is the primary beneficiary of UL-CCIC because UL Solutions has the power to direct many of the activities that most significantly impact the performance of the entity through its right to appoint a majority of the directors on UL-CCIC’s board of directors, as well as the exclusive right to nominate the general manager. Pursuant to the governing documents of UL-CCIC, certain decisions and actions of its board of directors require either unanimous approval or the approval of two-thirds of the directors, while certain other matters require either unanimous approval or the approval of a supermajority of the voting rights of the shareholders; however, the Company believes that such decisions and actions are not the most significant to the performance of UL-CCIC. As such, the Company consolidates UL-CCIC as a variable interest entity (“VIE”). The profits and losses of UL-CCIC are shared by the parties in proportion to their respective contributions to its registered capital. Such equity interest represents the Company’s variable interest in UL-CCIC and provides for participation in both the risk of loss and future economic gains. Neither UL Solutions nor CCIC, as the shareholders of UL-CCIC, are required to provided additional financing support to UL-CCIC.
UL-CCIC is a separate legal entity and its assets are legally owned by UL-CCIC and are not available to the Company’s creditors. UL-CCIC assets of $219 million and $193 million and liabilities of $94 million and $87 million, inclusive of intercompany eliminations, were included in the Company’s Consolidated Balance Sheets at December 31, 2025 and 2024, respectively.

Goodwill is tested for impairment annually in the fourth quarter, or more frequently if an event occurs or conditions change that would indicate it is more likely than not that the fair value of a reporting unit is below its carrying amount. During the three months ended September 30, 2023, the Company identified a triggering event and performed a quantitative impairment assessment for a reporting unit in the Consumer segment, which resulted in a pre-tax impairment charge of $37 million. This partial impairment charge was the result of lower than expected demand for Non-certification Testing and Other Services in the mobility industry, which was impacted by auto industry conditions in 2023, including slowing of the pace of electric vehicle transition, labor uncertainties, and the impact of more moderate growth expectations for the business. At December 31, 2025, the remaining goodwill related to this reporting unit was no longer considered at risk of further impairment.
The impairment assessment for this reporting unit consisted of a fair value calculation that combined an income approach and a market approach, using an equal weighting, and a number of significant assumptions including estimated future revenue growth rates, EBITDA margins, discount rate, and market multiples. The fair value using the income approach was determined based on the present value of the estimated future cash flows of the reporting unit, discounted using the weighted average cost of capital. The Company used its internally developed long-range plans to estimate future cash flows for the business, which included estimated future revenue growth rates and EBITDA margins. Development of the Company’s long-range plans includes consideration of current and projected levels of income for the reporting unit based on management’s plans for the business, business trends, market and economic conditions, as well as other relevant factors. The fair value using the market approach was derived from market multiples using comparable publicly traded companies for a group of benchmark companies. The selection of comparable businesses was based on the markets in which the reporting unit operates giving consideration to risk profiles, size, geography and diversity of products and services. These estimates and assumptions were considered Level 3 inputs under the fair value hierarchy. The Company believes the assumptions used in the impairment assessment are reasonable and consistent with assumptions that would be used by other market participants. However, such assumptions are inherently uncertain, and a change in assumptions could change the estimated fair value of the reporting unit. Therefore, future impairment charges could be required, which could have an adverse effect on the Company’s financial condition and results of operations.

Retirement Benefits [Abstract]  
Pension Postretirement Benefits Plans Pension and Postretirement Benefit Plans
Pension
The Company has various non-contributory defined benefit pension plans covering certain employees and retired employees of the Company, UL Research Institutes and UL Standards & Engagement. The benefits are based on years of service and participant compensation. The majority of the Company’s defined benefit plans are closed to new entrants. The pension amounts reported here represent the balances related to all participants in the plans, including those of the U.S. employees and former employees of UL Research Institutes and UL Standards & Engagement. The Company uses the spot rate approach for calculating service cost and interest cost.
The following table provides a reconciliation of changes in the defined benefit pension obligations and fair value of plan assets for the years ended December 31, and a statement of funded status as of December 31:

__________
(a)During 2025, the Company adopted an amendment related to its U.S. defined benefit pension plan to freeze all future benefit accruals effective December 31, 2025. The freeze resulted in a curtailment, which reduced the projected benefit obligation by $12 million, with a corresponding decrease in accumulated other comprehensive loss on the Company’s Consolidated Balance Sheet. There was no impact on the Company’s Consolidated Statements of Operations as a result of the curtailment.
(b)During 2025, the Company’s qualified pension plan in Canada purchased a group annuity contract to transfer the future benefit obligations of all inactive members of its plan to an insurance company. The annuity purchase resulted in a partial plan settlement, which reduced the projected benefit obligation by $16 million. The annuity purchase was funded by plan assets, and as such had no net impact on the Company’s Consolidated Balance Sheet. The impact on the Company’s Consolidated Statement of Operations was immaterial.

The expected rate of return on plan assets is determined based on long-term historical performance of plan assets, current asset allocation and expected future long-term asset returns.
The Company determines the discount rate used to measure plan liabilities as of the December 31 measurement date for the pension and postretirement benefit plans, which is also the date used for the related annual measurement assumptions. The Company uses the full Aon AA Above Median Yield Curve rather than a single discount rate.
The accumulated benefit obligation for the U.S. defined benefit pension plans was $318 million and $313 million at December 31, 2025 and 2024, respectively. The accumulated benefit obligation for all Non U.S. defined benefit pension plans was $101 million and $110 million at December 31, 2025 and 2024, respectively.

Pension Assets
The assets in the investment portfolio for defined benefit pension plans are diversified in a manner that is intended to achieve the return objective and reduce the volatility of returns on the assets. The Company’s investment objective is to ensure that funds are available to meet the plans’ benefit obligations when they become due. The overall investment strategy is to prudently invest plan assets into diversified equity and debt securities, as well as alternative investments, to achieve long-term return expectations. The plan relies on a total return strategy in which investment returns consist of both capital appreciation (both realized and unrealized), as well as current yield (interest and dividends) over a long-term period.

Valuation Methods
The Company follows ASC Topic 820, Fair Value Measurement, in determining the fair value of plan assets within the Company’s defined benefit pension plans.
Quoted market prices in active markets for all Level 1 investments were available at December 31, 2025 and 2024.
Level 2 investments include commingled funds invested in equity or fixed income investments in accordance with a stated set of fund objectives. The values of the commingled funds do not have publicly quoted prices in active markets and must trade through a broker. The fund administrator values the fund using the net asset value per fund share, derived from the quoted prices in active markets of the underlying securities.
Level 3 investments include several guaranteed investment contracts, government mandated pooled investments, and a private real estate fund. These investments do not have actively traded quotes as of December 31, 2025 and 2024, and require the use of unobservable inputs, such as indicative quotes from dealers, estimates provided by the fund managers and third-party property appraisals, to value these securities.
For the U.S. plan, the 2025 target investment allocation was 49% for equity strategies, 30% for fixed-income and cash strategies and 21% for alternative strategies. The 2024 target investment allocation was 48% for equity strategies, 30% for fixed-income and cash strategies and 22% for alternative strategies. Actual investment allocations may vary from target investment allocations due to prevailing market conditions. The Company regularly reviews actual investment allocations and periodically rebalances investments to achieve target allocations.

Postretirement Benefit Plans
The Company sponsors postretirement medical benefit plans for certain employees and former employees in the U.S. and Canada. The projected benefit obligation for these plans was $13 million and $12 million at December 31, 2025 and 2024, respectively. The net periodic benefit cost related to these plans for each of the years ended December 31, 2025, 2024 and 2023, as well as the expected contributions to these plans in 2026, is immaterial. The plans are closed to new entrants.
Defined Contribution Plans
The Company sponsors various defined contribution savings plans in the U.S., as well as certain international locations, that allow employees to contribute a portion of their pre-tax and/or after-tax income in accordance with plan specified guidelines.
Under specified conditions, the Company will contribute to certain savings plans based on the employee’s eligible pay and/or will match a percentage of the employee contributions up to certain limits. For the years ended December 31, 2025, 2024 and 2023, the expenses related to various defined contribution plans were $56 million, $46 million and $46 million, respectively.

(a)State taxes in California and Illinois made up the majority (greater than 50 percent) of the tax effect in this category.

The effective tax rate for the year ended December 31, 2025 of 26.6% was higher than the effective tax rate for the year ended December 31, 2024 of 16.9% primarily due to the impact of the Qualified Domestic Minimum Top-up Tax, a subset of the Pillar Two rules that became effective on January 1, 2025, as well as a reduction to uncertain tax positions in the year ended December 31, 2024.

Of the 1.9% U.S. nondeductible compensation in 2024, 1.0% is for the reduction to previously established deferred tax assets due to the Company becoming subject to Section 162(m) of the U.S. Internal Revenue Code, which limits U.S. public company compensation expenses of certain executive officers that were previously deductible as a private company. The remainder is related to current year compensation expense limitations.
Other reconciling items consist of non-deductible expenses such as meals and entertainment, transaction costs related to merger and acquisition activities, movement in valuation allowances, and general business credits such as research and development tax credits.

Deferred income taxes are recorded on the Consolidated Balance Sheets on a net basis by taxing jurisdiction. As of December 31, 2025, the Company had a net deferred income tax asset of $75 million, which consisted of $94 million classified as deferred income taxes and $19 million included within other liabilities. As of December 31, 2024, the Company had a net deferred income tax asset of $85 million, which consisted of $108 million classified as deferred income taxes and $23 million included within other liabilities.
As of December 31, 2025, the Company has approximately $64 million of deferred tax assets related to net operating loss (“NOL”) carryforwards primarily attributable to foreign affiliates. If not used, $9 million of deferred tax assets will be written off to reflect the reduction of the NOL carryforwards that will expire between 2026 and 2045, while the remaining carryforward is indefinite. The use of certain NOL carryforwards is limited due to rules regarding acquired tax attributes, loss sharing between group members, and business continuity. The valuation allowances represent a reduction to deferred tax assets, including certain NOLs, for which the realization is unlikely.
The Company has not recognized deferred tax liabilities in the U.S. with respect to its outside basis differences in most foreign affiliates. It is not practicable to determine the amount of unrecognized deferred tax liabilities on these earnings.

The total unrecognized tax benefits that, if recognized, would affect the Company’s effective tax rate were $7 million, $6 million and $30 million as of December 31, 2025, 2024 and 2023, respectively. The Company had accrued for interest and penalties of $2 million, $3 million and $12 million, as of December 31, 2025, 2024 and 2023, respectively, which are included within other liabilities in the Company’s Consolidated Balance Sheets.
The Company is under audit in multiple state and foreign tax jurisdictions. The timing of the resolution of income tax examinations is uncertain as are the amounts and timing of tax payments that are part of any audit settlement process. These events could cause fluctuations in the balance sheet classification of our tax assets and liabilities.
In the United States, the Company has open years ranging from 2016 to 2025 and significant foreign jurisdictions still open for audit between 2010 and 2025. The Company believes sufficient provision has been made for potential adjustments for all years that are not closed by the statute in all major tax jurisdictions and that any such adjustments would not have a material adverse effect on the Company’s financial position, liquidity, or results of operations.
On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted in the U.S. The OBBBA includes several corporate tax provisions that apply to the Company, such as the permanent extension of certain expiring provisions of the U.S. Tax Cuts and Jobs Act and modifications to the international tax framework and business interest expense limitations. The Company has assessed the impact of the OBBBA and has determined that there is no material impact to its consolidated financial statements.

(a) The term loans were repaid in full and terminated in connection with entry into the 2025 Credit Facility. See below.
The interest rate on the revolving credit facility was 4.78% as of December 31, 2025. The interest rate on the outstanding term loans was 5.58% as of December 31, 2024. Borrowings under the senior notes bear a fixed interest rate of 6.500% per annum.
2022 Credit Facility
In January 2022, the Company entered into a credit agreement with Bank of America, N.A. and certain other lenders, which provided for senior unsecured credit facilities in an aggregate principal amount of $1.25 billion (collectively, and as amended, the “2022 Credit Facility”), consisting of term loans in an initial aggregate principal amount of $500 million and revolving loan commitments in an initial aggregate commitment amount of $750 million (including a $25 million sub-facility for letters of credit). The 2022 Credit Facility included an accordion feature permitting an increase in the 2022 Credit Facility by an aggregate amount of up to $625 million (of which up to $400 million may consist of term loans), subject to the consent of any lenders providing such increase, the absence of any default or event of default and entry into customary documentation with respect to such increase. The Company’s wholly owned subsidiary, UL LLC, a Delaware limited liability company, provided a guaranty of its obligations thereunder. The 2022 Credit Facility was set to mature in January 2027 and could be prepaid without fees or penalties. The Company had $6 million outstanding in letters of credit, surety bonds, and performance and other guarantees with financial institutions as of December 31, 2024 under the 2022 Credit Facility.
In June 2024, the Company entered into an amendment (the “First Credit Facility Amendment”) to the 2022 Credit Facility with Bank of America, N.A. and certain other lenders. The First Credit Facility Amendment provided, among other things, for (i) the replacement of the Bloomberg Short-term Bank Yield (“BSBY”) with Term SOFR plus a SOFR adjustment as a benchmark rate for interest periods commencing subsequent to June 28, 2024; (ii) UL Solutions Inc., which was previously the guarantor of the facility, became the named borrower, and UL LLC, which was previously the named borrower, became the guarantor.
Effective from the date of the First Credit Facility Amendment, borrowings under the 2022 Credit Facility bore interest at a rate per annum equal to, at the Company’s option, (a) in the case of U.S. dollar loans, the Term SOFR plus a SOFR adjustment of 0.1% plus a margin, and for all other currencies, a specified benchmark rate for the applicable currency plus, in certain instances, a specified spread adjustment plus a margin (loans with a rate based on this clause (a), “benchmark rate loans”) or (b) for U.S. dollar loans only, the base rate plus a margin (loans with a rate based on this clause (b), “base rate loans”). Prior to the First Credit Facility Amendment, borrowings bore interest on the same terms with the exception that the BSBY Index rate plus a margin was used as the base rate in place of Term SOFR. As of December 31, 2024, the margin was 1.125% for benchmark rate loans and 0.125% for base rate loans but could be adjusted based on the Company’s most recently tested consolidated net leverage ratio and could vary from 1.0% to 1.5% for benchmark rate loans and 0% to 0.5% for base rate loans. The unused commitment fee could vary from 0.1% to 0.2% based on the Company’s most recently tested consolidated net leverage ratio.
The 2022 Credit Facility also included a financial covenant tested quarterly which required the Company to maintain a consolidated net leverage ratio of not greater than 3.5 to 1.0, calculated on a consolidated basis for each consecutive four
fiscal quarter period, with an increase in the maintenance level to 4.0 to 1.0 for each of the four test periods immediately following any permitted acquisition that involves the payment of aggregate consideration in excess of $100 million, subject to a two fiscal quarter rest period between increases for separate acquisitions. The calculation of the consolidated net leverage ratio permitted the netting of up to $250 million of unrestricted cash from funded debt.
The 2022 Credit Facility included customary representations and warranties, covenants and events of default, subject to certain customary exceptions, materiality thresholds and grace periods. The covenants included, among other things, financial reporting, maintenance of line of business, notices of default and other material changes, as well as limitations on investments and acquisitions, mergers and transfers of all or substantially all assets, dividends and distributions, burdensome contracts with affiliates, liens and indebtedness. Future borrowings under the 2022 Credit Facility were subject to the satisfaction of customary conditions, including the absence of any default or event of default and the accuracy of representations and warranties.
As described below, in connection with the entry into the 2025 Credit Facility, the Company repaid in full all indebtedness and other obligations outstanding under, and terminated, the 2022 Credit Facility.
2025 Credit Facility
In October 2025, the Company entered into a credit agreement, by and among the Company and certain of its non-U.S. subsidiaries as co-borrowers (collectively, the “Borrowers”), Bank of America, N.A., as administrative agent, and the lenders party thereto (the “Credit Agreement”).
The Credit Agreement provides for a $1.0 billion senior unsecured five-year multi-currency revolving facility (collectively, and as amended, the “2025 Credit Facility”), with a $25 million sub-limit for the issuance of letters of credit. The Credit Agreement includes an accordion feature permitting an increase in the 2025 Credit Facility by an aggregate amount of up to $500 million, subject to the consent of any lenders providing such increase, the absence of any default or event of default and entry into customary documentation with respect to such increase. The Borrowers’ obligations (other than the Company’s) under the Credit Agreement are guaranteed by the Company. Initial proceeds were used to refinance the outstanding amounts under the 2022 Credit Facility. The 2025 Credit Facility matures on October 28, 2030 and may be prepaid without fees or penalties, subject to reimbursement of the lenders’ customary breakage and redeployment costs in applicable cases. The Company had $6 million outstanding letters of credit under the 2025 Credit Facility as of December 31, 2025.
Borrowings under the 2025 Credit Facility bear interest at a rate per annum equal to, at the applicable Borrower’s option, (a) a specified benchmark rate for the applicable currency (which, in the case of U.S. Dollar loans, shall be the Term SOFR (as defined in the Credit Agreement)), plus a margin that ranges from 0.875% to 1.375% per annum or (b) for U.S. Dollar loans made to the Company only, a base rate (which is equal to the highest of (i) the Bank of America prime rate, (ii) the U.S. federal funds rate plus 0.5% per annum, or (iii) the Term SOFR rate plus 1%) plus a margin that ranges from 0.0% to 0.375% per annum. The unused commitment fee varies from 0.090% to 0.175% based on the Company’s current debt rating and its most recently tested consolidated net leverage ratio.
The 2025 Credit Facility also includes a financial covenant, tested quarterly, which requires the Company to maintain a consolidated net leverage ratio of not greater than 3.5 to 1.0, calculated on a consolidated basis for each consecutive four fiscal quarter period, with an increase in the maintenance level to 4.0 to 1.0 for each of the four test periods immediately following any permitted acquisition that involves the payment of aggregate consideration in excess of $100 million, commencing with the fiscal quarter in which such permitted acquisition occurred, subject to a two fiscal quarter rest period between increases for separate acquisitions. The calculation of the consolidated net leverage ratio permits the netting of up to $250 million of unrestricted cash from funded debt. As of December 31, 2025, the Company was in compliance with all covenants under this facility.
The 2025 Credit Facility includes customary representations and warranties, covenants and events of default, subject to certain customary exceptions, materiality thresholds and grace periods. The covenants include, among other things, financial reporting, maintenance of line of business, notices of default and other material changes, as well as limitations on investments and acquisitions, mergers and transfers of all or substantially all assets, dividends and distributions, burdensome contracts with affiliates, liens and indebtedness. Future borrowings under the 2025 Credit Facility are subject to the satisfaction of customary conditions, including the absence of any default or event of default and the accuracy of representations and warranties.
Senior Notes
In October 2023, the Company issued $300 million in aggregate principal amount of 6.500% senior notes due 2028 (the “notes”). The notes were sold to qualified institutional buyers in the United States in reliance on Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) and to non-U.S. persons outside the United States in reliance on Regulation S under the Securities Act. The notes are senior unsecured obligations of UL Solutions Inc. and were unconditionally guaranteed by UL LLC, the Company’s wholly owned subsidiary, until October 2025. In connection with termination of the 2022 Credit Facility, the guaranty by UL LLC of the Company’s obligations under the notes was released. The Company used the net proceeds from the offering of the notes, together with borrowings under the 2022 Credit Facility and cash on hand, to fund a $600 million special cash dividend, which was paid to UL Standards & Engagement in December 2023.
In connection with the issuance of the notes, the Company entered into a registration rights agreement on the same date. In September 2025, pursuant to the registration rights agreement, the Company completed an exchange offer, pursuant to which the Company exchanged all of the outstanding notes for new 6.500% senior notes due 2028 registered under the Securities Act (the “exchange notes”). The terms of the exchange notes are substantially the same as the notes.
UL Solutions pays interest on the notes semi-annually in arrears on April 20 and October 20 of each year, which began on April 20, 2024.
Pursuant to the indenture that governs the notes (the “indenture”), there are certain limitations on the ability of the Company and its restricted subsidiaries to create or incur liens and to enter into sale and leaseback transactions. The indenture also imposes certain limitations on the ability of the Company to merge, consolidate or amalgamate with or into any other person (other than a merger of a wholly owned subsidiary into the Company) or sell, transfer, assign, lease, convey or otherwise dispose of all or substantially all of the property of the Company in any one transaction or series of related transactions. These limitations are subject to significant exceptions.
If a change of control triggering event occurs, as defined in the indenture, UL Solutions will be required to offer to purchase the notes at a price equal to 101% of their principal amount, together with accrued and unpaid interest, if any. The Company may also redeem some or all of the notes at any time prior to their maturity pursuant to the indenture’s provisions and limitations.
As of December 31, 2025, the remaining aggregate scheduled principal repayments of the Company’s debt are as follows:

Share-Based Payment Arrangement [Abstract]  
Stock-based and Other Incentive Compensation Stock-based and Other Incentive Compensation
In April 2024, the UL Solutions Inc. 2024 Long-Term Incentive Plan (the “2024 LTIP”) became effective and the Company reserved for issuance 20,000,000 shares of Class A common stock in connection with the 2024 LTIP and the UL Solutions Inc. Long-Term Incentive Plan (the “Pre-IPO LTIP”), as well as 5,000,000 additional shares of Class A common stock reserved for issuance under the UL Solutions Inc. 2024 Employee Stock Purchase Plan (the “2024 ESPP”). Upon settlement of stock-based compensation awards, shares of Class A common stock are issued in respect of such awards. Equity awards that are granted and subsequently expire, are cancelled, forfeited, or are used to satisfy required withholding taxes are recycled back into the total number of shares available for issuance under the 2024 LTIP and the Pre-IPO LTIP. As of December 31, 2025, 19,248,048 shares remain available for issuance under the 2024 LTIP and the Pre-IPO LTIP and 4,725,988 shares remain available for issuance under the 2024 ESPP.
Equity awards are issued to certain employees and officers, including named executive officers, in order to attract, motivate and retain talent and to maximize their contribution to the long-term success of the Company. Equity awards are also used as part of the compensation provided to the board of directors in the form of restricted stock units. Directors may elect to defer receipt of some or all of their annual cash retainer amounts, which are converted into restricted stock units when and as such cash retainer amounts would have otherwise been paid, for either 5 years, 10 years or until termination of service from the board.
The Company has outstanding awards under the Pre-IPO LTIP, the majority of which will be settled in shares of Class A common stock.

The total fair value of RSUs that vested during the year was $16 million for the year ended December 31, 2025. As of December 31, 2025, total unrecognized compensation expense related to RSUs was $27 million and is expected to be recognized over the remaining weighted-average vesting period of 1.9 years.
Performance Share Units
Performance share units (“PSUs”) represent the right to receive shares of Class A common stock based on the achievement of certain performance conditions and are generally subject to continued employment through a three-year cliff vesting period. The performance conditions are based on company-wide non-GAAP revenue and operating income metrics and the number of Class A common shares issued may range from 0% to a maximum potential value of 200% of the award’s target value based on the satisfaction of the applicable metrics over a three-year cumulative performance period.

In connection with the IPO, the Company granted nonqualified stock options to the Company’s executive team, including named executive officers, and other key employees under the 2024 LTIP. Stock options represent the right to purchase shares of Class A common stock and are generally subject to continued employment through a three-year cliff vesting period.

As of December 31, 2025, total unrecognized compensation expense related to stock options was $7 million and is expected to be recognized over the remaining weighted-average vesting period of 1.3 years.
Stock Appreciation Rights
The Company has stock appreciation rights outstanding from its Pre-IPO LTIP, which represent the right to receive an amount based on the appreciation in the fair value of the Company’s Class A common stock from the grant date up to a specified date or dates. Prior to the IPO, all stock appreciation rights were Cash-settled Stock Appreciation Rights
(“CSARs”). Upon completion of the IPO, the majority of outstanding CSARs were converted to the same number of Stock-settled Stock Appreciation Rights (“SSARs”), which will be settled in shares of Class A common stock under the Pre-IPO LTIP. As equity-settled awards, the fair value of the SSARs was determined on the conversion date of April 16, 2024 and, generally, will not be remeasured unless the awards are modified.
The conversion of CSARs to SSARs at the completion of the IPO resulted in a reclassification of $26 million from accrued compensation and benefits and other liabilities to additional paid-in capital on the Company’s Consolidated Balance Sheet. The CSARs were remeasured to fair value at the conversion date, which resulted in additional pre-tax compensation expense of $9 million in the second quarter of 2024, primarily within selling, general and administrative expenses. The pre-tax compensation expense reduced segment operating income by $4 million, $4 million and $1 million for the Industrial, Consumer and Software & Advisory segments, respectively. As of December 31, 2025 and 2024, the unrecognized compensation expense related to the Company’s remaining CSARs and SSARs, as well as liabilities related to the Company’s outstanding CSARs, were immaterial.
Performance Cash
The Company has Performance Cash awards outstanding from its Pre-IPO LTIP, which represent the right to receive an amount based on the achievement of certain performance conditions and are generally subject to continued employment through a three-year cliff vesting period. The amount may range from 0% to a maximum potential value of 200% of the award’s target value based on the satisfaction of the performance conditions over a three-year cumulative performance period. Prior to the IPO, all Performance Cash awards were settled in cash. Following the IPO, the majority of the outstanding Performance Cash awards will be settled in shares of Class A common stock under the Pre-IPO LTIP. During 2025, $16 million of Performance Cash was settled in Class A common stock, resulting in a reclassification from accrued compensation and benefits to additional paid-in capital on the Company’s Consolidated Balance Sheet.
Compensation expense related to Performance Cash awards for the years ended December 31 was as follows:

The Company had a long-term liability of $0 and $18 million recorded within other liabilities in the Consolidated Balance Sheets at December 31, 2025 and 2024, respectively.

Restructuring Restructuring
On November 4, 2025, the Company announced an expense reduction initiative to further improve the operating model and exit certain lines of business that are no longer considered strategically important to the Company (the “Restructuring Plan”). Inclusive of the charges recorded in 2025, the Company expects to incur pre-tax charges associated with the Restructuring Plan of approximately $42-$47 million in the aggregate, consisting of $37-$42 million in cash charges relating to employee separation expenses and approximately $5 million in other cash charges, primarily relating to facility exits.
The Company has incurred total costs to date of $33 million related to employee separation expenses and $4 million related to facility exits in connection with the Restructuring Plan. The Company has incurred total costs to date of $28 million in Consumer, $7 million in Industrial, and $2 million in Software and Advisory related to the Restructuring Plan. The Company anticipates the Restructuring Plan will be substantially completed by the end of the first quarter of 2027, with the remaining charges primarily expected to be incurred in the first half of 2026 in the Consumer segment.
The Company has incurred the following charges related to the Restructuring Plan, as well as other qualifying restructuring expenses, for the years ended December 31:

Loss Contingencies
On February 11, 2026, a putative class action complaint was filed against Underwriters Laboratories Inc., UL LLC, the Company, UL Standards and Engagement and UL Research Institutes (collectively, the “Defendants”) in the United States District Court for the Northern District of Illinois captioned John Martucci, on behalf of himself and the Putative Class v. Underwriters Laboratories Inc., et al., Case No. 1:26-cv-01561. The complaint alleges, among other things, that certain combination-listed single databus burglar and fire alarm system control units (the “Alarm Systems”) tested by the Defendants have defects that the Defendants concealed from and/or failed to disclose to consumers and that the Defendants listed the Alarm Systems as compliant with UL and National Fire Protection Association 72 standards when they were not compliant
with such standards. The complaint seeks an order certifying a nationwide class and a New Jersey subclass; compensatory, actual, treble, statutory, punitive, and/or other damages; equitable relief, including restitution and disgorgement of profits; injunctive relief; declaratory relief; and pre and post judgment interest, attorneys’ fees and costs. The Company currently believes the claims are without merit and intends to vigorously defend against this action. A reasonable estimate of the amount of any possible loss or range of loss cannot be made at this time.
The Company is party in the ordinary course of business to certain claims, litigation, audits and investigations. The Company will record an accrual for a loss contingency when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company believes it has established adequate accruals for liabilities that are probable and reasonably estimable and that may be incurred in connection with any such currently pending or threatened matter, none of which are material. In the Company’s opinion, the settlement of any such currently pending or threatened matter is not expected to have a material impact on the Company’s financial position, results of operations, or cash flow.

Segment Reporting [Abstract]  
Segment Information Segment Information
ASC Topic 280, Segment Reporting (“ASC 280”) establishes the standards for reporting information about segments in financial statements. The Company has determined that it is organized, managed and internally grouped into three segments: Industrial, Consumer and Software and Advisory. UL Solutions segments provide common goods and services to their customers, which provides for efficient sharing of the segments’ resources as needed. Segment information is reported on the basis used for reporting to the Chief Executive Officer, who serves as the Company’s chief operating decision maker (“CODM”) and evaluates each segment’s performance using a variety of measures, including operating income, which is the measure most consistent with amounts included in the Company’s consolidated financial statements. The CODM uses operating income, amongst other measures, to evaluate each segment’s performance and allocate resources, including employees and capital, considering budget-to-actual variances to review operating trends in the annual budgeting and quarterly forecasting processes.
The following is a brief description of the Company’s segments:
Industrial: The Industrial segment provides testing, inspection and certification (“TIC”) services to help ensure customers’ industrial products meet or exceed international standards for product safety, performance and sustainability. The Industrial segment provides services that address needs across a number of end markets, including energy, industrial automation, engineered materials (plastics and wire and cable) and built environment, and across a variety of stakeholders, including manufacturers, building and asset owners, end users and regulators. The Company believes the products it tests, certifies and inspects in this segment generally represent very high cost of failure components, which in turn drives customers in this segment to choose UL Solutions based on its deep technical expertise, consistency and quality of service.
Consumer: The Consumer segment provides a variety of global product market acceptance and risk mitigation services for customers in the consumer products end market, including consumer electronics, medical devices, information technologies, appliances, HVAC, lighting, retail (softlines and hardlines) and emerging consumer applications, including new mobility, smart products and 5G. The primary services offered by this segment include safety certification testing, ongoing certification, global market access, testing for connectivity, performance and quality and critical systems advisory and training.
Software and Advisory: The Software and Advisory segment provides complementary software and advisory solutions that extend the value proposition of TIC services the Company offers. The software and technical advisory offerings enable the Company’s customers to manage complex regulatory requirements, deliver supply chain transparency and operationalize sustainability.
The accounting policies applied to the segments are the same as those applied by the Company to the consolidated financial statements. The Company prepared the financial results of the segments on a basis that is consistent with the manner in which management internally disaggregates financial information to assist in making internal operating decisions. The Company manages income taxes and certain treasury related items, such as interest income and expense, on a global basis within corporate.
The Company allocates among segments certain common costs and expenses not specifically identifiable to the segments differently than the Company would for stand-alone financial information prepared in accordance with US GAAP. These include certain costs and expenses of the Company’s corporate functions, such as executive, finance, legal, human resources and information technology. Allocations are calculated primarily based on segment expenses proportionate to consolidated expenses.

Segment Realignment
Effective beginning in the first quarter of 2026, the Company reorganized its segments to be consistent with how the Chief Executive Officer will evaluate business performance and allocate resources. The changes primarily relate to the Company’s Advisory business, which was previously included within the Software and Advisory segment and will now be included within the Industrial segment. As a result of the reorganization, the Software and Advisory segment will be renamed “Risk & Compliance Software” and costs related to the Company’s corporate functions will be reallocated across its segments. This reorganization had no impact on the Company’s consolidated financial position, results of operations or cash flows.
Divestiture
In February 2026, the Company signed a definitive agreement to sell its Employee Health and Safety software business in the Company’s Risk & Compliance Software segment to an affiliate of Peak Rock Capital, a private investment firm, for a base purchase price of $210 million in cash, subject to customary post-closing adjustments. The transaction is expected to close in the second quarter of 2026, subject to the satisfaction of customary closing conditions.

Significant Accounting Policies (Policies)
 12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and variable interest entities for which the Company has determined it is the primary beneficiary. All intercompany accounts and transactions have been eliminated. The Company accounts for investments in businesses using the equity method when it has significant influence but not control (generally between 20% and 50% ownership) and is not the primary beneficiary. The significant accounting policies, as summarized below, conform to accounting principles generally accepted in the United States of America (“US GAAP”). The Company has reclassified certain amounts in prior period financial statements to conform to the current period’s presentation.
Use of Estimates
Use of Estimates
The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the 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. Estimates are inherently uncertain and actual results could differ materially from estimated amounts. Estimates are used for, but are not limited to, contractual revenue recognized, future cash flows associated with impairment testing for goodwill, certain assumptions related to pension and postretirement benefits and income taxes. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Cash and Cash Equivalents
Cash and Cash Equivalents
Cash and cash equivalents include investments purchased with original maturities of three months or less.
Accounts Receivable and Contract Assets
Accounts Receivable and Contract Assets
Accounts receivable consists of trade receivables billed and currently due from customers as well as amounts currently due from other external parties. Contract assets represent revenues for projects that have been recognized for accounting purposes, but not yet billed to customers. The Company’s standard payment terms are due upon receipt of the invoice, except for certain customers, which may be required to make advance payments.
The Company extends credit to customers in the normal course of business, generally not longer than 90 days, and maintains an allowance for credit losses. The allowance is an estimate based on historical collection experience, current and future economic and market conditions and a review of the current status of each customer’s trade accounts receivable. Management evaluates the aging of the accounts receivable balances and the financial condition of its customers and all other forward-looking information that is reasonably available to estimate the amount of accounts receivable that may not be collected in the future and records the appropriate provision. Account balances are written off against the allowance when it is determined the accounts receivable will not be recovered.
Concentration of Credit Risk
Concentration of Credit Risk
Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents, accounts receivable and contract assets. Credit risk represents the accounting loss that would be recognized at the reporting date if counterparties failed to perform as contracted. The Company believes the likelihood of incurring material losses due to concentration of credit risk is minimal. The Company actively limits its exposure to credit risk by maintaining cash deposits with major financial institutions as counterparties and by maintaining accounts receivable with a large number of customers in diverse industries and geographies in addition to establishing reasonable credit approvals and limits.
Property, Plant and Equipment
Property, Plant and Equipment
Property, plant and equipment are stated at cost, net of accumulated depreciation. Major replacements and improvements are capitalized, while maintenance and repairs, which do not improve or extend the life of the respective assets, are expensed as incurred. Gains and losses resulting from sales and retirements are included within operating income.
Goodwill
Goodwill
The Company accounts for business combinations using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, which requires an allocation of the purchase consideration transferred to the identifiable assets and liabilities based on the estimated fair values as of the acquisition date. Goodwill represents the excess of the purchase price of an acquired entity over the fair value of net assets acquired. Goodwill is tested for impairment annually in the fourth quarter, or more frequently if an event occurs or conditions change that would indicate it is more likely than not that the fair value of a reporting unit is below its carrying amount. The Company’s reporting units have been identified as one level below its operating segments. The goodwill impairment testing is performed by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value.
To evaluate the recoverability of a reporting unit’s goodwill the Company has the option to first perform a qualitative analysis. If the qualitative analysis indicates it is more likely than not that the fair value of a reporting unit is below its carrying amount, the Company performs a quantitative impairment assessment for that reporting unit.
The Company’s quantitative assessment consists of a fair value calculation for each reporting unit that combines an income approach and a market approach, using an equal weighting. The quantitative assessment requires the application of a number of significant assumptions which are further described below, including estimated future cash flows of the reporting unit, discount rates, and market multiples.
The fair value using the income approach is determined based on the present value of estimated future cash flows of the reporting unit, discounted at an appropriate risk‑adjusted rate. The Company uses its internally developed long-range plans to estimate future cash flows, which include an estimate of long‑term future growth rates based on its most recent views of the long‑term outlook for each reporting unit. Development of the Company’s long-range plans includes consideration of current and projected levels of income for the reporting unit based on management’s plans for that business, business trends, market and economic conditions, as well as other relevant factors. The discount rate is based on the weighted average cost of capital for the reporting unit. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the respective businesses and in the Company’s long-range plans.
The fair value using the market approach is derived from market multiples using comparable publicly traded companies for a group of benchmark companies. The selection of comparable businesses is based on the markets in which the reporting units operate giving consideration to risk profiles, size, geography and diversity of products and services.
During the three months ended September 30, 2023, the Company identified a triggering event and performed a quantitative impairment assessment for a reporting unit in the Consumer segment, which resulted in a pre-tax impairment charge of $37 million. Refer to Note 9, “Goodwill” for further details. The Company did not recognize any impairments of goodwill for the years ended December 31, 2025 or 2024.
Intangible And Other Long-lived Assets
Intangible and Other Long-lived Assets
The Company amortizes finite-lived intangible assets using the straight-line method over their estimated economic useful lives, which range from three to twenty years. The Company reviews long-lived assets, including property, plant and equipment, capitalized software and intangible assets with finite lives for impairment whenever an event occurs or conditions change that indicate the carrying amount of the asset group may not be recoverable. When such events occur, the Company performs a recoverability test by comparing the projected undiscounted cash flows of the asset group to the carrying amount. If this comparison indicates that there is a potential impairment, the asset group’s fair value is determined based on the present value of its estimated future cash flows, discounted at an appropriate risk-adjusted rate. An impairment charge is recorded for the amount by which the carrying amount of the asset group exceeds its fair value. The Company did not recognize any material impairments of intangible or other long-lived assets for the years ended December 31, 2025, 2024 or 2023.
Leases
Leases
The Company determines if an arrangement is a lease at inception and reassesses that conclusion if the contract is modified. The Company evaluates whether the arrangement conveys the right to control the use of an identified asset for a period of time in exchange for consideration in order to determine if the contract is or contains a lease. The right to control the use of an identified asset includes the right to obtain substantially all of the economic benefits from use of the asset and the right to direct the use of the asset.
The Company’s classes of leased assets include real estate, vehicles, and equipment. When it is reasonably certain that an option to extend or terminate a lease will be exercised, the Company includes the option in the recognition of right-of-use (“ROU”) assets and lease liabilities. The Company does not recognize ROU assets or lease liabilities for leases with a term of twelve months or less. The Company accounts for lease and non-lease components as a single component for all asset classes.
ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at lease commencement and measured based on the present value of lease payments over the lease term. Variable lease payments, which may include certain non-lease costs such as real estate taxes, common area maintenance and insurance, are recognized as incurred and are not presented as part of the ROU asset or lease liability, unless such payments are fixed or in-substance
fixed, which may include payments that depend on an underlying index or rate. Operating lease cost is recognized on a straight-line basis over the lease term. The Company does not have material finance leases.
The Company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. The Company’s incremental borrowing rate is based on its estimated rate of interest for a collateralized borrowing over a similar term as the lease payments. The same process is followed for any new leases at their commencement dates or modification to existing leases that require remeasurement.
Capitalized Software
Capitalized Software
Costs related to software acquired or developed solely for the Company’s internal use, as well as costs to develop cloud-based applications provided to customers as a service (i.e. SaaS arrangements) are capitalized in accordance with ASC Topic 350-40, Internal-use Software (“ASC 350-40”). Certain costs incurred after the completion of the preliminary project stage and after management, with the relevant authority, has authorized and committed funds to the software project, and it is probable that the project will be completed and the software will be used to perform the function intended, are capitalized. For development costs capitalized under the requirements of ASC 350-40, amortization begins when each software module is ready for its intended use. Costs are amortized on a straight-line basis over the estimated useful life of the software (generally three to five years). Costs related to preliminary project activities and post implementation activities are expensed as incurred. Additions to capitalized software are reported within capital expenditures in the Consolidated Statements of Cash Flows.
The Company capitalizes certain implementation costs related to cloud computing service arrangements with third-party vendors that are incurred during the application development stage. Subsequently, the costs are amortized on a straight-line basis over the non-cancelable term of the hosting agreement plus any reasonably certain renewal periods. Capitalized implementation costs are included as a component of other assets on the Consolidated Balance Sheets and amortization is included as an operating expense in the Consolidated Statements of Operations. Additions to capitalized cloud implementation costs are reported within operating activities in the Consolidated Statements of Cash Flows.
Costs related to software to be sold, leased or otherwise marketed are expensed as incurred until technological feasibility has been established in accordance with ASC Topic 985-20, Costs of Software to be Sold, Leased, or Marketed. Certain costs incurred subsequent to establishing technological feasibility are capitalized up until the software is available for general release, and are amortized on a straight-line basis over the estimated useful life of the software (generally three to five years).
Accounts Payable and Contract Liabilities
Accounts Payable and Contract Liabilities
Accounts payable consists of trade payables currently due to vendors as well as amounts currently due to other external parties. Contract liabilities include payments received in advance of performance under the contract and are subsequently reduced when the associated revenue is recognized for the respective contract. Amounts initially recorded as contract liabilities are recognized as revenue in accordance with the Company’s revenue recognition policy.
Fair Value
Fair Value
The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short maturities. For fair value of the Company’s debt see Note 6.
ASC Topic 820, Fair Value Measurement (“ASC 820”), defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:
•Level 1 observable inputs such as quoted prices in active markets;
•Level 2 inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
•Level 3 unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.
ASC 820 requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. The Company does not have any assets or liabilities measured at fair value on a recurring basis that are Level 3, except for certain pension assets discussed in Note 11. The Company did not have any transfers between fair value levels during the years ended December 31, 2025 and 2024.
Revenue Recognition
Revenue Recognition
The Company recognizes revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), when its customer obtains control of promised goods or services, or as the Company renders services, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods and services. For each arrangement the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligation(s) in the contract, (3) determine the transaction price, (4) if applicable, allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the Company satisfies a performance obligation.
The Company’s contracts with customers generally relate to services that are distinct and are accounted for separately. Those goods and services that are determined to be separate performance obligations are treated as separate units of account and each separate performance obligations has its own stand-alone selling price, which is the price at which an entity would sell a promised good or service separately to a similar customer in similar circumstances. The stand-alone selling price is determined using an established list price for the specific service and geographical region, or through a needs-based assessment. If a needs-based assessment approach is used, the stand-alone selling price is estimated by multiplying the expected labor hours by a labor rate. The labor rate is determined by considering the cost of labor, other miscellaneous costs (e.g., overhead) and applying a margin. The labor rate may be adjusted for geographic differences and other items as determined necessary, and is reviewed on a periodic basis for appropriateness.
The majority of the Company’s revenue from contracts with customers represents revenue from services recognized over time as performance obligations are satisfied. Revenue from over-time arrangements is recognized either on a straight line basis as the service is provided to the customer, or using an input method, which requires the Company to make estimates, in particular in relation to measuring progress towards completion. For arrangements recognized over time using an input method, progress towards completion is based on the relationship between the time elapsed of each project phase relative to the expected duration of that phase. The portion of a project’s revenue to be recognized is determined based on the time elapsed between the start-date of each project phase relative to its estimated duration. The start-date of each phase is based on the date that work begins on the phase and the estimated duration is determined using an analysis of historical data from similar projects. Management applies judgment in determining the expected duration of each phase. The portion of a project’s revenue estimated as earned, but not yet completed, and recognized as revenue, is included in contract assets or as a reduction to contract liabilities.
The Company’s cost to obtain a contract is generally commission paid to sales personnel for the sale of services. Management determined that the amortization period of the commission costs would be one year or less and therefore has elected the practical expedient to expense these costs as incurred. As a result, the costs to obtain a contract are expensed as incurred.
The Company typically does not incur costs to fulfill contracts which would meet the capitalization criteria and therefore these costs are typically expensed as incurred. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.
Refer to Note 3, “Revenue” for additional information.
Cost of Revenue
Cost of revenue includes employee compensation consisting of salaries, incentives, stock-based compensation and other benefits for employees directly attributable to revenue generation across each of the Company’s four major service categories. In addition, cost of revenue includes services and materials expenses including facility related costs for laboratories and other buildings where testing and inspection services are performed, customer-related travel costs, expenses related to third party contractors or third party facilities and consumable materials and supplies used in testing and inspection and other costs associated with generating revenue. Cost of revenue also includes depreciation on equipment used in testing and amortization of capitalized software sold to customers.
Description of Major Service Categories
Certification Testing
The Company evaluates products, components and systems according to global or regional regulatory requirements and other design and performance specifications. Select certification testing services include testing to global or regional standards, engineering evaluation and project review and functional safety testing of embedded software. Certification testing services generally align with the new product development cycle and help customers mitigate risk, demonstrate compliance with regulatory requirements and deliver confidence to businesses and consumers, resulting in demand for ongoing certification services. As a result of the certification process, the Company may authorize its customers to use the Company’s certification marks, including the Company’s registered UL-in-a-circle certification mark (the “UL Mark”), on their products, packaging and marketing collateral as part of their manufacturing, distribution and marketing processes to demonstrate to the marketplace that their product has met the applicable requirements. Certification testing services often lead to Ongoing Certification Services to support the continued safety, compliance and performance objectives of the customer.
Contracts are generally structured as fixed payments as the total amount to be charged to the customer does not vary. Revenue from Certification Testing is generally recognized over-time. In these cases, the services create an asset with no alternative use as each of the services are specific to the products and specifications provided by the customer, and the Company has an enforceable right to payment. Revenue is generally recognized based on the relationship between the time elapsed of each project phase relative to the expected duration of that phase, which is considered the most indicative of the Company’s performance to-date under the terms of the contract.
In some instances, revenue from Certification Testing does not meet the over-time criteria and is recognized at a point in time when control is transferred to the customer. Control is transferred to the customer upon the delivery of the test report to the customer. These instances occur when the agreement or the nature of the services causes a lack of right to payment until control transfer.
Ongoing Certification Services
To maintain the right to use the Company’s certification marks, including the UL Mark, and meet certain regulatory requirements, the Company’s customers must meet certain certification program requirements, including mandatory inspection and monitoring by the Company. These requirements, addressed through standard certification and inspection services, are designed to validate the continued compliance of the Company’s customers’ previously certified products, components and systems. Services are delivered through periodic inspections, initial and follow-up audits, sample testing and UL Solutions label usage. The frequency and combination of these services can vary based on product, component or system type, production volume and historical risk-based customer compliance. These ongoing certification services are designed and executed to help the Company’s customers confirm ongoing compliance and to help protect the integrity of the UL Mark. Select services include factory inspection and testing to confirm products that are being produced match the configuration of products that were tested and certified.
Contracts are generally structured as fixed payments as the total amount to be charged to the customer does not vary. In some cases, the customer is charged a usage price based on its total production volume. Revenue from compliance program contracts is recognized over-time on a straight-line basis because the customer receives and consumes the benefit of continued certification as the Company performs services through the periodic verification of the customer’s compliance.
As part of Ongoing Certification Services, customers may order physical labels (recorded in other current assets) that bear the UL Mark to affix to their products to demonstrate to end-customers that the products comply with the certification requirements of the Company. The labels are a separate performance obligation, distinct from the compliance program. Revenue from physical labels is recognized upon shipment, the point in time in which the customer obtains control of the labels.
Non-certification Testing, and Other Services
The Company offers testing services to address performance and other requirements that may not be required by any regulation and may not result in a certification, but are still desired by the Company’s customers to help ensure the safety, performance and reliability of their products. Select services include on-site and remote inspections, audits and field engineering specialty services, testing for energy efficiency, wireless and electromagnetic compatibility, quality, chemical and reliability for customers in medical devices, information technologies, appliances, HVAC and lighting. For retail and consumer customers, the Company offers testing such as color-matching, sensory, emissions and flame resistance. Lastly, the Company offers advisory and technical services to support the Company’s customers in managing their safety, compliance, regulatory risk and sustainability programs.
Contracts are generally structured as fixed payments as the total amount to be charged to the customer does not vary. For services where the customer does not simultaneously receive and consume the benefit of the performance obligation, revenue is recognized upon the delivery of the final deliverables to the customer. For services that create an asset with no alternative use as each of the services are specific to the products and specifications provided by the customer, and the Company has an enforceable right to payment, revenue is generally recognized based on the relationship between the time elapsed of each project phase relative to the expected duration of that phase, which is considered the most indicative of the Company’s performance to date under the terms of the contract. Advisory revenue is generally recognized over time.
In some instances, revenue from non-certification testing does not meet the over-time criteria and is recognized at a point in time when control is transferred to the customer. Control is transferred to the customer upon the delivery of the test report to the customer. These instances occur when the agreement or the nature of the services causes a lack of right to payment until control transfer.
Software
The Company provides software as a service (“SaaS”) and license-based software solutions, including implementation and training services related to software, to enable the Company’s customers to manage complex regulatory requirements, deliver supply chain transparency and operationalize sustainability. The Company’s SaaS and licensed software solutions provide data-driven product stewardship, chemicals management, supply chain insights, environmental, social and governance (“ESG”) data and reporting, environmental, health and safety (“EHS”) training, management and compliance, and additional regulatory driven software solutions.
Contracts are structured as fixed payments as the total amount to be charged to the customer does not vary. The Company generally recognizes revenue from SaaS contracts, which are provided on a subscription basis, ratably over the contract period beginning on the date the service is first made available to the customer. The Company generally recognizes revenue from on-premise software at a point in time when it is made available to the customer. The revenue from implementation services, post-contract customer support services, and other customer support services is recognized over the service period as the customer benefits from the services as they are performed.
Selling, General and Administrative Expenses
Selling, General and Administrative Expenses
Selling, general and administrative expenses include employee compensation consisting of salaries, incentives, stock-based compensation and other benefits for sales and indirect administrative functions such as executive, finance, legal, human resources and information technology, not included within cost of revenue. In addition, selling, general and administrative expenses include services and materials expenses including third party consultancy costs, facility costs, internal research and development costs as well as legal and accounting fees, travel, marketing, bad debt and non‑chargeable materials and supplies. Selling, general and administrative expenses also include depreciation and amortization.
Foreign Currency
Foreign Currency
The functional currency of certain of the Company’s foreign affiliates is the local currency. Assets and liabilities of international subsidiaries have been translated into U.S. dollars at the balance sheet date, and income and expense items have been translated using monthly average exchange rates for the period. The resulting currency translation adjustments have been recorded as a separate component of other comprehensive income (loss). The Company revalues assets and liabilities entered in foreign currency at the balance sheet date and the resulting unrealized gain (loss) is recorded as other (expense) income, net in the Consolidated Statements of Operations.
Stock-based Compensation
Stock-based Compensation
The Company maintains long-term incentive plans under which equity awards are available to be issued to certain employees, officers and directors. Stock-based compensation expense, measured as the fair value of an award on the date of grant, is recognized ratably over the requisite service period, which is generally equal to the vesting period of the respective award, however, it may be impacted by certain factors including the employee’s death, disability or retirement. Compensation expense related to performance share units is adjusted each reporting period based on the probable outcome of the performance conditions applicable to each grant.
The fair value of restricted stock units and performance share units is determined using the closing price of the Company’s stock on the date of grant. The fair value of each stock option is measured on the date of grant using a Black-Scholes-Merton option-pricing model that uses various assumptions including expected stock price volatility, expected dividend yield, the risk-free interest rate, and expected term of the award.
Restructuring
Restructuring expenses consist of employee-separation costs, including severance and other benefits calculated based on long-standing benefit practices and local statutory requirements. In most jurisdictions, the Company has ongoing benefit arrangements under which the Company records estimated severance and other termination benefits when such costs are deemed probable and estimable, approved by management, and if actions required to complete the termination plan indicate it is unlikely that significant changes to the plan will be made or the plan will be withdrawn. Severance and other termination benefits for which there is not an ongoing benefit arrangement are recorded when management has committed to the plan and the benefit arrangement is communicated to the affected employees. Other costs may include facility exit costs related to accelerated right-of-use asset amortization, gains and losses on early lease terminations, and other exit costs for leases which will be abandoned, as well as professional services costs related to restructuring activities.
Other Income (Expense), net
Other (Expense) Income, net
Other (expense) income, net consists primarily of non-operating gains and losses, including gains and losses related to foreign exchange transactions and the revaluation performed on designated balance sheet accounts, interest income, gains and losses on equity investments, non-operating pension and postretirement benefit expenses and gains on divestitures.
Interest Expense
Interest Expense
Interest expense consists primarily of interest expense on the Company’s debt obligations.
Income Taxes
Income Taxes
The Company recognizes income taxes based on amounts refundable or payable for the current year and records deferred tax assets or liabilities for temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, net operating loss carryforwards and tax credit carryforwards. Deferred tax assets and liabilities are measured using current enacted tax rates expected to apply to taxable income in the years in which temporary differences are expected to reverse. Inherent in determining the annual tax rate are judgments regarding business plans, planning opportunities and expectations about future outcomes. Realization of certain deferred tax assets, primarily net operating loss and other carryforwards, is dependent upon generating sufficient taxable income in the appropriate jurisdiction prior to the expiration of the carryforward periods. The Company has classified all deferred tax assets and liabilities, along with any related valuation allowances, as net non-current on the Consolidated Balance Sheets. Deferred tax expense or benefit is the result of changes in the deferred tax asset or liability.
The Company records valuation allowances to reduce deferred tax assets to reflect the amount that is more-likely-than-not to be realized. When assessing the need for valuation allowances, the Company considers all available evidence, including three years of cumulative income/(loss) before taxes, expected future taxable income and ongoing prudent and feasible tax planning strategies. Should a change in circumstances lead to a change in judgment about the realizable value of deferred tax assets in future years, the Company would adjust related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income.
For uncertain tax positions related to exposures associated with various tax filing positions, the Company recognizes a tax benefit only if it is more‑likely‑than‑not that the tax position will be sustained upon examination by the relevant taxing authorities, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that is more‑likely‑than‑not to be realized upon settlement. The Company adjusts its liability for unrecognized tax benefits in the period they are settled, the statute of limitations expires, or when new information becomes available. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense.
The Company has generated income in certain foreign jurisdictions that may be subject to additional foreign withholding taxes and U.S. state income taxes, if repatriated. The Company regularly reviews its plans for reinvestment or repatriation of unremitted foreign earnings and has recorded deferred tax liabilities on certain foreign subsidiaries’ unremitted earnings that are not considered permanently reinvested. The Company’s assertion on indefinite reinvestment of foreign earnings is based upon assumptions of future liquidity needs of the business and cash flow projections of its subsidiaries.
The accounting policy of the Company is to record U.S. tax on Global Intangible Low-Taxed Income in the provision for income taxes in the year it is incurred.
Recently Issued Accounting Standards - Adopted and Not Adopted
Recently Issued Accounting Standards – Adopted
Effective for the year ended December 31, 2025, the Company adopted Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. The ASU was adopted prospectively and did not impact the Company’s financial condition, results of operations or cash flows. Refer to Note 12, “Income Taxes” for further information.
Recently Issued Accounting Standards – Not Adopted
In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures, which is intended to improve disclosures about a public business entity’s expense and provide more detailed information to investors about the types of expenses in commonly presented expense captions. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, on either a prospective or retrospective basis, with early adoption permitted. The Company expects to adopt the new annual disclosure as required for the year ended December 31, 2027 and the interim disclosures as required beginning with the first quarter of 2028. The application of this new guidance is not expected to have a material impact on the Company’s consolidated financial condition, results of operations, or cash flows, as the guidance pertains to disclosure only.
In September 2025, the FASB issued ASU No. 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments are intended to modernize the recognition and capitalization framework to reflect current software development practices, including iterative and agile methodologies, by removing references to “development stages” and clarifying the threshold to begin capitalizing costs. The amendments in ASU 2025-06 are effective for fiscal years beginning after December 15, 2027, and interim periods within those annual reporting periods, on either a prospective, modified transition or retrospective basis, with early adoption permitted. The Company is currently evaluating the impact this ASU may have on its consolidated financial statements.
In November 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. The amendments are intended to improve US GAAP by establishing authoritative guidance on the accounting for government grants received by business entities. The amendments in ASU 2025-10 are effective for fiscal years beginning after December 15, 2028, and interim periods within those annual reporting periods, on either a modified prospective, modified retrospective or retrospective basis, with early adoption permitted. The Company is currently evaluating the impact this ASU may have on its consolidated financial statements.
Segment Information
ASC Topic 280, Segment Reporting (“ASC 280”) establishes the standards for reporting information about segments in financial statements. The Company has determined that it is organized, managed and internally grouped into three segments: Industrial, Consumer and Software and Advisory. UL Solutions segments provide common goods and services to their customers, which provides for efficient sharing of the segments’ resources as needed. Segment information is reported on the basis used for reporting to the Chief Executive Officer, who serves as the Company’s chief operating decision maker (“CODM”) and evaluates each segment’s performance using a variety of measures, including operating income, which is the measure most consistent with amounts included in the Company’s consolidated financial statements. The CODM uses operating income, amongst other measures, to evaluate each segment’s performance and allocate resources, including employees and capital, considering budget-to-actual variances to review operating trends in the annual budgeting and quarterly forecasting processes.
The accounting policies applied to the segments are the same as those applied by the Company to the consolidated financial statements. The Company prepared the financial results of the segments on a basis that is consistent with the manner in which management internally disaggregates financial information to assist in making internal operating decisions. The Company manages income taxes and certain treasury related items, such as interest income and expense, on a global basis within corporate.
The Company allocates among segments certain common costs and expenses not specifically identifiable to the segments differently than the Company would for stand-alone financial information prepared in accordance with US GAAP. These include certain costs and expenses of the Company’s corporate functions, such as executive, finance, legal, human resources and information technology. Allocations are calculated primarily based on segment expenses proportionate to consolidated expenses.

__________
(a)During 2025, the Company adopted an amendment related to its U.S. defined benefit pension plan to freeze all future benefit accruals effective December 31, 2025. The freeze resulted in a curtailment, which reduced the projected benefit obligation by $12 million, with a corresponding decrease in accumulated other comprehensive loss on the Company’s Consolidated Balance Sheet. There was no impact on the Company’s Consolidated Statements of Operations as a result of the curtailment.
(b)During 2025, the Company’s qualified pension plan in Canada purchased a group annuity contract to transfer the future benefit obligations of all inactive members of its plan to an insurance company. The annuity purchase resulted in a partial plan settlement, which reduced the projected benefit obligation by $16 million. The annuity purchase was funded by plan assets, and as such had no net impact on the Company’s Consolidated Balance Sheet. The impact on the Company’s Consolidated Statement of Operations was immaterial.

(a)State taxes in California and Illinois made up the majority (greater than 50 percent) of the tax effect in this category.

The effective tax rate for the year ended December 31, 2025 of 26.6% was higher than the effective tax rate for the year ended December 31, 2024 of 16.9% primarily due to the impact of the Qualified Domestic Minimum Top-up Tax, a subset of the Pillar Two rules that became effective on January 1, 2025, as well as a reduction to uncertain tax positions in the year ended December 31, 2024.
