Cautionary Note Regarding Forward-Looking Statements

This Annual Report on Form 10-K for the year ended December 31, 2024 (“Annual Report”) contains forward-looking statements as defined by the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts contained in this Annual Report may be forward-looking statements. Statements regarding the Company’s future results of operations and financial position, business strategy and plans and objectives of management for future operations, including, among others, statements regarding the Company’s expected growth and future capital expenditures are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “would,” “likely,” “expects,” “plans,” “anticipates,” “could,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential,” “continue” and variations of these terms and similar expressions, or the negative of these terms or similar expressions (although not all forward-looking statement may contain such words). The Company cautions you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements.

There are or will be important factors that could cause the Company’s actual results to differ materially from those indicated in these forward-looking statements, including, but not limited to, the following:

•any failure on the Company’s part to protect and maintain its brand and reputation, or the impact on its brand or reputation of third-party events or actions outside of its control;

•risks associated with conducting business outside the United States, including those relating to fluctuations in foreign currency exchange rates; enhanced trade, import or export restrictions; and global, regional or political instability;

•risks associated with the Company’s operations in China, which subject the Company and UL-CCIC Company Limited, the Company’s joint venture with the China Certification & Inspection (Group) Co., Ltd. (“CCIC”), to China’s complex and rapidly evolving laws, which may be interpreted, applied or enforced inconsistently or in ways inconsistent with its current operations, as well as risks associated with the fact that the Chinese government has the power to exercise significant oversight and discretion over, and intervene in and influence, its business operations in China;

•the relationship between the United States and China and between the Company and CCIC, as well as changes in U.S. and Chinese regulations affecting the Company’s business operations in China;

•any failure on the Company’s part to attract, hire or retain its key employees, including its senior leadership and its skilled and trained engineering, technical and professional personnel;

•the level of the Company’s customers’ satisfaction and any failure on its part to properly and timely perform its services, meet its contractual obligations or fulfil its customers’ needs;

•a change in the assumptions the Company uses to value its goodwill or intangible assets, or the impairment of its goodwill or intangible assets;

•constraints imposed on the Company’s ability to operate its business or make necessary capital investments due to the Company’s outstanding indebtedness;

4

•the increased expenses and responsibilities associated with being a public company;

•the significant influence that UL Standards & Engagement has over the Company, including pursuant to its rights under the Company’s amended and restated certificate of incorporation and the Stockholder Agreement with UL Standards & Engagement;

•natural disasters and other catastrophic events, including pandemics and the rapid spread of contagious illnesses;

•changes in tax laws in jurisdictions in which we operate or adverse outcomes resulting from examination of our or our affiliates tax returns; and

•the other factors discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in the “Risk Factors” in Part I Item 1A of this Annual Report.

The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included in the section titled “Risk Factors” in Part I Item 1A of this Annual Report and the Company’s subsequent filings with the Securities and Exchange Commission (“SEC”). If one or more events related to these or other risks or uncertainties materialize, or if the Company’s underlying assumptions prove to be incorrect, actual results may differ materially from what the Company anticipates. Many of the important factors that will determine these results are beyond the Company’s ability to control or predict. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and, except as otherwise required by law, the Company does not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. If the Company updates one or more forward-looking statements, no inference should be drawn that the Company will make additional updates with respect to those or other forward-looking statements. New factors emerge from time to time, and it is not possible for the Company to predict which will arise. In addition, the Company cannot assess the impact of each factor on the Company’s business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements attributable to the Company, or others acting on the Company’s behalf, are expressly qualified in their entirety by the cautionary statements above.

In addition, statements that “the Company believes” and similar statements reflect the Company’s beliefs and opinions on the relevant subject. These statements are based upon information available to the Company as of the date of this Annual Report, and while the Company believes such information forms a reasonable basis for such statements, such information may be limited or incomplete, and the Company’s statements should not be read to indicate that the Company has conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

You should read this Annual Report and the documents that the Company references in this Annual Report with the understanding that the Company’s actual future results, levels of activity, performance and achievements may be materially different from what the Company expects.

PART I

ITEM 1. Business

Our Company

UL Solutions Inc. (together with its consolidated subsidiaries, “UL Solutions”, the “Company”, “we”, “our”, and “us”) is a global safety science leader that provides Testing, Inspection and Certification (“TIC”) services and related software and advisory offerings to customers worldwide. We work for a safer world. Our mission drives our actions, inspires our employees and is the key to our success. We strive to be our customers’ most trusted science-based safety, security and sustainability partner. Our history dates back to our founding in 1894 as part of the nonprofit Underwriters Electrical Bureau, a predecessor to Underwriters Laboratories Inc. (“UL Research Institutes”), ULSE Inc. (“UL Standards & Engagement”) and UL Solutions. UL Research Institutes is the sole member of UL Standards & Engagement, which controls the majority of the voting power of our common stock.

As the largest TIC services provider headquartered in North America (by revenue) with a global network of laboratories, we provided a comprehensive set of product safety, security and sustainability solutions to more than 80,000 customers across over 110 countries in 2024. Our distinguished heritage and our long history of operating at the forefront of safety science enables us to achieve and maintain more than 650 technical accreditations and 76 commercial software solutions, and to remain active in over 1,300 standards panels and technical committees globally, which underpins the expertise we offer to our customers. Furthermore, we offer over 400 independent third-party conformity assessment services around the world and are capable of testing and certifying against over 4,000 global standards, which affords us vast insight into the safety of products across a wide range of end markets and geographies. We are the owner of the iconic UL Mark that appears on billions of products around the world. We offer our customers global market access services that help them ensure the safety and quality of their products while also supporting their efforts to manage the broader risks they face throughout their product lifecycle processes.

The outsourced product TIC market, where we currently focus, is served by our Industrial and Consumer segments, which provide comprehensive testing, inspection and certification services to customers across a broad array of end markets. Our Software and Advisory (“S&A”) segment is a global provider of software, data and advisory solutions, enabling our customers to manage complex regulatory requirements, deliver supply chain transparency and operationalize sustainability. We generate revenue in these segments and the following service categories: Certification Testing; Ongoing Certification Services; Non-certification Testing and Other Services; and Software. As the global economy continues to evolve and becomes more digital and inter-connected, our customers continue to seek ways to bridge traditional TIC needs with next generation cloud-based software and services to better mitigate risk and enhance their business performance.

Our Segments

Industrial

Our Industrial segment provides TIC services to help ensure that our customers’ industrial products meet or exceed international standards for product safety, performance, cybersecurity and sustainability. Our services 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. We believe the products we test, certify and inspect in this segment generally represent very high cost of failure components, which in turn drives customers in this segment to choose providers like us based on our deep technical expertise, consistency and quality of service.

Consumer

Our 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 and 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.

6

Software and Advisory

Our S&A segment provides complementary software and advisory solutions that extend the value proposition of TIC services we offer. The software and technical advisory offerings enable our customers to manage complex regulatory requirements, deliver supply chain transparency and operationalize sustainability.

Our Strategy for Growth

We intend to leverage our capabilities and reputation as a trusted science-based safety, security and sustainability leader to drive growth in our current capabilities, as well as in new areas where we can add value to our customers. Consistent with our demonstrated track record, our growth strategy consists of continued expansion from organic opportunities supplemented by targeted, accretive M&A. Our growth strategy is focused on: (i) Growing and Expanding Our Core, (ii) Deploying Capital for Acquisition-Related Growth and (iii) Employing Operational Strategies to Expand Margins.

Growing and Expanding Our Core

We will enhance our core businesses by further expanding our comprehensive service capabilities across attractive verticals where we have market leadership today or in new industries that would benefit from our expertise, providing new solutions for adjacent risk areas and extending our service capabilities beyond products and components.

These growth strategies include:

Increase our share of wallet with current and new customers. We believe that there are opportunities to expand offerings to customers, and thereby our wallet share, given the rising financial and reputational costs of safety failure and increasing regulatory compliance requirements. Our key commercial strategies are focused on providing new services that address evolving customer needs and accelerating cross-sell and up-sell activity. We also seek to expand the role we currently play with our customers throughout their product lifecycles by moving beyond product testing into adjacent services that address our customers’ needs as they bring products to market.

Expand presence in new industry verticals. We continue to seek opportunities to address safety needs within existing verticals, as well as in emerging growth verticals, that would benefit from our core technical expertise and our ability to support global product market access. We are constantly monitoring the market to identify new demand drivers for our services, and we will continue to expand into existing and new verticals as conditions dictate.

Expand TIC service offerings.We have a sizeable opportunity to expand our TIC services to reflect the growing interconnectivity of our world and the new safety, security and sustainability needs of industrial and consumer products that result therefrom. Our customers rely on our deep expertise in innovative and cost-effective solutions as the safety and regulatory environment changes and requires them to seek additional third-party TIC support. As an example, security, affordability and sustainability are driving rapid innovation of the energy industry. Today’s energy landscape is complex, connected and bidirectional, requiring many new components and systems, all of which must be evaluated for compatibility, stability and safety.

Expand S&A offerings. As our core TIC customer needs have evolved, we have extended our business beyond product testing to serve as a global provider of software, data and advisory solutions, enabling our customers to manage complex regulatory requirements, deliver supply chain transparency and operationalize sustainability. S&A offerings allow us to serve a broader addressable market and represent a significant growth opportunity and recurring revenues with existing and new customers. In 2024, approximately 65% of our global and strategic accounts cross-purchased software and advisory solutions to complement their core TIC needs, driving business growth with attractive recurring revenues. One key expansion area is supply chain software that enables many of the world’s largest retailers and manufacturers, among others, to effectively evaluate and ensure regulatory compliance, chemical safety and sustainability across their products. On January 31, 2024, we launched ULTRUS, our new brand that unites our flagship software that helps customers meet regulatory, supply chain and sustainability challenges.

Deploying Capital for Acquisition-Related Growth. The global TIC industry remains highly fragmented with many sub-scale competitors in operation. We use acquisitions to grow our core and expand into attractive adjacencies and end markets that add capabilities to better serve our customers. Our strong balance sheet and free cash flow profile will continue to provide significant flexibility to pursue highly accretive bolt-on and transformational acquisitions.

7

Employing Operational Strategies to Expand Margins. As we continue to increase our scale, we prioritize excellence across our operations to help drive profit margin improvement. To achieve this margin expansion, we employ operational strategies that focus on service delivery excellence and the management of speed, cost and quality through the relentless focus on exceptional customer experience and through digital and other innovations in our service delivery. These strategies are complemented by a culture of continuous improvement, our standardized performance metrics and the ongoing introduction of new internal technology that enables us to constantly streamline our operations. Further, we leverage our deep pool of human capital, along with our vast network of offices and laboratories, to drive operating efficiencies and margin expansion.

Our Service Offerings

We generate our revenue through four major service categories (percent of revenue for 2024):

Certification Testing (approximately 27% of revenue). We evaluate 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, we may authorize our customers to use our certification marks, including 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.

Ongoing Certification Services (approximately 33% of revenue). To maintain the right to use our certification marks, including the UL Mark, and meet certain regulatory requirements, our customers must meet certain certification program requirements, including mandatory inspection and monitoring by us. These requirements, addressed through standard certification and inspection services, are designed to validate the continued compliance of our 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. Our ongoing certification services are designed and executed to help our 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.

Non-certification Testing and Other Services (approximately 30% of revenue). We offer 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 our 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, we offer testing such as color-matching, sensory, emissions and flame resistance. Lastly, we offer advisory and technical services to support our customers in managing their safety, compliance, regulatory risk and sustainability programs.

Software (approximately 10% of revenue). We provide SaaS and license-based software solutions, including implementation and training services related to software, to enable our customers to manage complex regulatory requirements, deliver supply chain transparency and operationalize sustainability. Our 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.

Our Team and Talent Management

We employ leading talent, with technical expertise throughout the organization. As of December 31, 2024, we had a total of 14,813 full-time employees and 281 part-time employees. Our technical team of approximately 9,800 scientists, engineers and other specialized technical and regulatory experts has been purpose-built over many years and is core to our competitive differentiation. As of December 31, 2024, our highly experienced employee base had an average tenure with UL Solutions of nine years with us or our affiliates, and our technical talent had an average tenure of ten years, which instills trust within our customers and provides superior outcomes in safety, security and sustainability.

8

None of our U.S.-based employees are covered by collective bargaining agreements, although approximately 10% of our employees are represented by foreign trade unions and work councils in the Americas, the APAC region, Europe, the Middle East and Africa, which could subject us to arrangements very similar to collective bargaining agreements. In Europe, approximately 18% of our workforce are represented by work council committees. We have not experienced any work stoppages or strikes that have had a material adverse impact on our operations. We consider our relationships with our employees to be collaborative.

Talent, Engagement and Development

Our talent management strategy is to attract, grow and retain a global and diverse workforce through performance reward and development programs. Our talent development programs include on-the-job training, professional development, internal and external partner leadership programs, organizational development and a self-service curriculum. As part of our broader employee development process, our proprietary UL University (“ULU”) program provides education and training to all of our employees through a comprehensive portfolio of instructor-led, online and self-directed learning options.

Information Technology

Our information technology capabilities provide a competitive advantage by allowing us to focus on enhancing the customer experience and internal operational efficiencies. Our information technology is underpinned by our centrally managed IT, security and digital teams, collectively guided by a comprehensive strategy and multi-year roadmap that reflect opportunities to improve the customer experience, employee productivity and cybersecurity.

Our employees benefit from common global processes and decision support capabilities that are supported by leading commercial-off-the-shelf technologies, such as Oracle, Microsoft and Salesforce.

Our customers value the trusted information we generate and the data we provide, which are supported by our strategy to deliver a common user experience and base platform through proprietary, customer-facing digital solutions. Our unified, consistent processes provide a fully connected customer experience across our businesses, improving customer satisfaction and ultimately improving our performance. These customer-facing digital solutions complement our TIC business by providing our customers with digital tools to help augment and manage testing, certification, inspection, in-market data and compliance, while supporting customers in improving productivity, quality and sustainability. Examples of current initiatives include:

•We are currently digitizing information gathering and analysis to provide the most cohesive and effective TIC software solutions to help customers achieve efficiencies throughout their product lifecycle.

•“myUL,” a one-stop self-service portal used by customers to securely access their UL Solutions project files, key product information and inspection reports real-time, which allows them to make better informed and timely decisions.

•UL Product iQ portal, which is used to access detailed certification information of UL Solutions-certified products.

Competition

We operate in a global and highly fragmented industry that is diverse across geographies, services and markets. Although the global TIC market has a number of large, global market participants, the broader market landscape remains highly fragmented and the majority of the markets we serve remain competitive on a global and local level. We are subject to competition from large and global public firms, such as Intertek, SGS, Bureau Veritas and Eurofins. We also compete with large private players, including Element, TÜV Rheinland, TÜV SÜD, DEKRA and DNV. In our S&A segment, we tend to compete against a diverse group of point solution providers. We believe the primary competitive advantages of our services are our capabilities, global reach, large installed base of laboratories and equipment, reputation and operational track record. Additionally, we believe we have a competitive advantage over our peers through the integrity of our work as an independent third party recognized by governments and international bodies. Our technical expertise and safety science thought leadership drives our accreditation management capabilities, which provide a high degree of business continuity and reliability to our customers.

9

Government Regulation and Compliance

Our business is subject to a number of laws and regulations, both within and outside the U.S., in areas such as data privacy, anti-bribery and corruption, international trade, taxation, environmental protection and others. We are required to maintain credentials from accreditors, regulators and scheme owners based on applicable regulations and scheme rules in order to provide conformity assessment services to our customers globally. These credentials reflect our conformity assessment bodies’ meeting of competency, consistency and impartiality requirements within those regulations and scheme rules. We have a global governance structure in place to facilitate compliance with these requirements.

Our current key credentials include those granted by key regulators and authorities in North America, Asia (including Greater China) and Europe. Typically, such credentials are critical in serving customers in highly regulated sectors, such as the medical device industry; in sectors where third-party providers are relied upon, such as the electrical and electronic equipment industry; and in highly regulated markets, such as mainland China.

Our global governance structure includes the active management of successful renewal of such credentials, the expansion or consolidation of these credentials, where warranted, and the pursuit of new credentials to preserve and to enable our ability to serve customers continuously.

Some of our credentials are granted by government agencies in North America, Asia (including mainland China) and Europe. For example, we have credentials issued by the U.S. Occupational Safety & Health Administration (“OSHA”) and the China National Certification and Accreditation Administration (the “CNCA”), which are among some of the key credentials for our operations.

Environmental Matters

Our business is subject to various international, federal, state and local laws and regulations regarding EHS matters. Among other things, these laws and regulations regulate the emission or discharge of materials into the environment, require us to obtain and maintain permits and approvals, govern the use, storage, treatment, disposal, transportation and management of hazardous substances, radioactive materials and wastes and protect the health and safety of our employees. These laws also impose liability for the costs of investigating, remediating, and addressing damages resulting from present and past releases of hazardous substances, including releases by prior owners or operators of sites we currently own or operate. Our previous ownership and current and previous operation of real property may also subject us to liability pursuant to these laws or regulations.

Compliance with EHS laws and regulations increases our operating costs, limits or restricts the services we provide, or the methods by which we offer, sell and fulfill those services or conduct our business, and subjects us to the possibility of regulatory or private actions or proceedings. In addition, violations of EHS laws and regulations could result in significant administrative, civil, or criminal penalties, remedial cleanups, natural resource damages, permit modifications or revocations, operational interruptions or shutdowns and other liabilities. We maintain an environmental, health and safety compliance program, including policies and standards, dedicated staff, and periodic auditing and training. Compliance with laws regulating contamination and the discharge of materials into the environmental, or otherwise relating to the protection of the environment or human health and safety, have not had a material effect on our capital expenditures, earnings, or competitive position, and are not currently material to our total operating costs or cash flows. However, environmental liabilities can change substantially, including due to changes in laws and regulations, and any future violations of applicable laws or regulations could adversely affect our financial condition and results of operations.

There has been a trend in favor of increased restrictions and limitations on activities that may affect the environment, and thus there can be no assurance as to the amount or timing of future expenditures for environmental compliance or remediation, and actual future expenditures may be different from the amounts we currently anticipate. For example, climate change continues to attract considerable public and scientific attention, and numerous proposals have been, and will likely continue to be, introduced to monitor and limit emissions of greenhouse gases. While we cannot predict future developments, the adoption and implementation of new or more stringent international, federal, regional, or state legislation, regulations, or other regulatory initiatives that impose more stringent standards for greenhouse gas emissions could result in increased costs of compliance. There were no material capital expenditures for environmental control facilities in 2022, 2023 or 2024, and there are no material investments currently planned for 2025; however, we may make material expenditures related to such facilities in the future.

10

Intellectual Property

Our intellectual property is an important part of our business. We rely on a combination of trademark, patent, copyright, trade secret and other related laws and confidentiality policies and contractual provisions to protect, maintain and enforce our proprietary technology and intellectual property rights. Our intellectual property portfolio also includes various registered and unregistered copyrights and internet domain names.

We believe many of our service marks, certification marks, trademarks and trade names are important to our success, and as of December 31, 2024, our trademark portfolio included approximately 116 registered U.S. trademarks and approximately 14 pending U.S. trademark applications, and approximately 2,000 registered trademarks and 150 pending trademark applications in other countries. We endeavor to take prudent measures to protect our trademarks and certification marks against counterfeiting and other forms of infringement and, in turn, maintain the value and integrity of our trademarks and certification marks for us and our customers who make the decision to pursue UL certification and carry the UL Mark on their products. We do this by, among other things, using a global trademark watch service; recording our marks with customs agencies around the world; engaging in opposition proceedings in various trademark offices; sending cease-and-desist letters to counterfeiters and other infringers and pursuing legal action against them where appropriate; and partnering with customers, code authorities and law enforcement to provide them with tools and information necessary to distinguish between authentic and counterfeit UL Marks so that we may work together in diverting any authorized UL marked product out of the stream of commerce.

As of December 31, 2024, we had approximately 21 issued U.S. patents and approximately 23 U.S. patent applications pending, all in various stages of examination. We cannot assure you whether any of our trademark or patent applications will result in the issuance of a trademark registration or patent, as applicable, or whether the examination process will require us to narrow the scope of protection that we are seeking. Any of our existing trademark registrations or patents and any that are issued in the future may be contested, circumvented, found unenforceable, cancelled or invalidated, and we may not be able to prevent third parties from infringing them.

For a discussion of risks related to our intellectual property, see “Risk Factors—Risks Related to Our Intellectual Property.”

Seasonality

While seasonality is not a significant factor in our financial performance, our total revenue is typically lowest in the first quarter and highest in the fourth quarter, primarily due to timing of Non-certification Testing and Other Services revenue within our Industrial and Consumer segments. In addition, our cash flow from operations is typically lowest in the first quarter due to payment of the prior year’s annual performance-based variable incentive compensation.

UL-CCIC Agreement

ITEM 1A. Risk Factors

UL Solutions’ business is subject to various risks and uncertainties. The following summary highlights some of the risks the Company is exposed to in the normal course of its business activities. If any of these risks actually occur, the Company’s business, financial condition or results of operations could be materially and adversely affected. This summary is not complete and the risks summarized below are not the only risks the Company faces. You should review and consider carefully the risks and uncertainties described in more detail following this summary in this Item 1A of Part I, which includes a more complete discussion of the risks summarized below, as well as a discussion of other risks related to the Company’s business and an investment in its Class A common stock.

Summary Risk Factors

•Because the Company’s success depends substantially on the value of its brand and reputation, any adverse publicity, damage to its brand or loss of reputation could impact the demand for its services, erode its market share or otherwise have a material adverse effect on its business.

•The Company or the third parties that it interacts with face cybersecurity risks and may fail to adequately secure or maintain the confidentiality, integrity or availability of data held as a result of a compromise of systems or data, which could result in a material adverse effect on the Company’s business and operations, and it may incur increasing costs in an effort to mitigate this risk.

•Technological advances in artificial intelligence (“AI”) may in the future disrupt the TIC or S&A industries, which could significantly reduce the demand for the Company’s services.

•The Company’s business is highly competitive. If the Company fails to compete successfully, to innovate in response to changing customer needs, new technologies or other market requirements, to develop new proprietary solutions, to increase the functionality of its current solutions or to develop its reputation as a technology leader, its business, financial condition and results of operations could be adversely affected.

•The Company maintains significant international operations and is subject to a variety of risks associated with doing business outside the United States, including difficulties associated with maintaining compliance with numerous laws and regulations, general economic, social and political conditions in countries where it operates and the need to expand into, and compete in, new jurisdictions resulting from shifts in supply chains.

•The Company may be adversely affected by global and regional economic and political instability.

•The Company conducts significant business in China, including through its joint venture with CCIC, and is therefore subject to China’s laws and regulations, which can be complex and evolve rapidly. The Chinese government has the power to exercise significant oversight and discretion over the conduct of the Company’s business in China, and the laws and regulations to which it is subject may change rapidly and with little notice. These laws and regulations may be interpreted, applied or enforced inconsistently by different agencies or authorities and may be inconsistent with or restrictive of the Company’s current operations. Any new or changed regulations and policies could result in a material change in the Company’s operations and could have a material adverse effect on its business. The Chinese government may also intervene in or influence the Company’s business in China at any time, without notice, including placing restrictions on its operations in China.

•Changes in the economic policies of the government of China could have a significant impact on the business the Company may be able to conduct in China and the profitability of its business.

•The Company’s success depends upon its ability to recruit, train and retain key employees, including its senior leadership and its trained and skilled engineering, technical and professional personnel.

•The Company works with dangerous materials and in dangerous environments that could injure its employees, contractors or customers, damage its or its customers’ facilities, disrupt its or its customers’ operations and could otherwise result in significant costs, liabilities and obligations.

•The Company is subject to risks related to sustainability and corporate social responsibility.

12

•A conflict of interest or perceived conflict of interest between the Company’s testing, inspection or certification services, on the one hand, and its advisory and other services, on the other hand, could adversely impact its accreditation or its reputation or expose it to legal liability.

•Changes to relevant regulatory frameworks resulting in a reduction in required inspections, tests or certifications, any requirement that the Company accept third-party test results or certifications in lieu of collecting its own data and conducting its own tests, and the harmonization of international or cross-industry benchmarks and standards, in each case, could lead to the reduction in demand for, or commoditization of, the Company’s services, which could have a material adverse effect on the Company’s business, financial condition and results of operations.

•The Company’s business depends substantially on the level of its customer satisfaction and specifically on customers maintaining their agreements with the Company and purchasing additional services from the Company, a significant decline in any of which could harm the Company’s business, financial condition and results of operations.

•Part of the Company’s growth strategy is to pursue strategic transactions, including acquisitions, and the Company may not be able to find suitable acquisition targets or achieve its desired acquisition objectives.

•Allegations of the Company’s failure to properly perform its services may expose it to potential product and other liability claims, recalls, penalties and reputational harm or could otherwise cause a material adverse effect on the Company’s business.

•Any failure to obtain, maintain, adequately protect or enforce the Company’s intellectual property and proprietary rights could impair the Company’s ability to protect its proprietary technology, the UL Mark and its brand.

•Any unethical conduct by the Company’s employees, agents, contractors, partners, Underwriters Laboratories Inc. (“UL Research Institutes”) or ULSE Inc. (“UL Standards & Engagement”) could result in financial penalties or affect the Company’s brand, reputation or image, any of which could have a material adverse impact on its business, financial condition and results of operations.

•Changes in, a significant delay in obtaining, failure to obtain or the withdrawal or revocation of the Company’s licenses, approvals, accreditations or other authorizations or delegations of authority would likely have a material adverse effect on the Company’s business, financial condition and results of operations.

•The Company is currently defending certain litigation, and it is likely to be subject to additional litigation in the future, any of which could be costly to defend and may harm the Company’s reputation.

•The substantial ownership of the Company’s common stock by UL Standards & Engagement, together with the dual class structure of the Company’s common stock and UL Standards & Engagement’s governance and consent rights under the Company’s Amended and Restated Certificate of Incorporation and that certain Stockholder Agreement, dated as of April 2, 2024, by and between the Company and UL Standards & Engagement, concentrates voting control with UL Standards & Engagement for the foreseeable future, which will limit the ability of the Company’s other stockholders to influence corporate matters, including the election or removal of directors and the approval or rejection of any change of control transaction.

•The Company may not be able to generate sufficient cash to service all of its indebtedness, and may be forced to take other actions to satisfy its obligations under its indebtedness, which may not be successful.

•As a result of becoming a public company, the Company has incurred, and will continue to incur, significant costs related to being a public company, and management will be required to devote substantial time to compliance with the Company’s public company responsibilities and corporate governance practices.

Risks Related to Our Industry and Business

Because our success depends substantially on the value of our brand and our reputation as a market leader in the TIC services industry, adverse publicity, damage to our brand or a loss of reputation could impact the demand for our services or erode our market share or otherwise have a material adverse effect on our business.

13

Our reputation and the value of our brand are critical to our business. Adverse publicity concerning the quality or effectiveness of our services, safety or non-compliance issues with products we have tested or certified, whether or not directly relating to or involving the services we performed, and other matters, including adverse publicity about, or events relating to, UL Research Institutes, UL Standards & Engagement or their research or standard-setting activities (which we cannot control), could result in the loss of our existing customer relationships, our inability to attract new customers, legal claims, government or regulatory investigations, increased insurance costs or diminished trust from AHJs, all of which could adversely affect our business and operations. The value of our brand and our reputation could be severely damaged even by isolated incidents, particularly if the incidents receive considerable negative publicity or result in substantial litigation.

Any such incidents, and any resulting adverse publicity, may arise from events that are beyond our control, such as international trade disputes, regulatory changes, market fluctuations, supply chain constraints, actions taken by our customers, employees or other third parties and poor quality control in our customers’ manufacturing processes. For example, part of our businesses involve testing and inspecting products, facilities, processes, components and systems against various legal, regulatory, industry and customer standards and requirements, but we do not serve as an AHJ or other enforcement body in connection with such testing and inspection services. Misunderstandings regarding our role in our customers’ compliance processes or the failure by our customers or other third parties to appropriately and effectively use and act on the findings of our assessments could lead to reputational harm. In addition, from time to time, our customers and others make claims and take legal action against us, UL Research Institutes or UL Standards & Engagement. Whether or not any such claims have merit, they may adversely affect our reputation, our customers’ trust in our brand and the demand for our services. Demand for our services could also diminish significantly if any such incidents or other matters erode general confidence in us or our services, which would likely result in reputational damage or lower sales, either of which could materially and adversely affect our business and results of operations.

The TIC industry is currently highly competitive and fragmented, and our ability to effectively compete depends heavily on our brand and reputation. Any real or perceived issues with delivering our services to our customers or our failure to provide high-quality services to our customers could adversely affect our brand and reputation. Our customers may no longer choose us over our competitors and our relevance with key stakeholders, such as AHJs, may be diminished. This, in turn, could cause us to lose market share and our market leadership position, which could have a material adverse effect on our financial condition and results of operations. Further, if there is increased consolidation in the TIC industry in the future amongst our competitors, it may result in the loss of our market leadership position as competitors with greater financial, marketing and technical resources emerge, As a result, the demand for our products and services could decrease, which could have a material adverse effect on our financial condition, results of operations and cash flows.

Technological advances in AI may in the future disrupt the TIC industry, which could significantly reduce the demand for our services.

The success of our TIC business depends on sustained demand for our services, which are carried out by our employees who leverage a broad range of technological advances to perform their work. For example, the majority of our TIC services are performed by skilled technicians, engineers, scientists and regulatory experts at our various facilities or on-site at our customers’ facilities. As AI technology continues to evolve, tasks currently performed by people, including those performed by our employees, may be augmented or replaced by automation, robotics, AI/machine learning and other technological advances. These technological advances also have the potential to enable the development of alternative competitive services or enable our customers to reduce or bypass the use of our services. If any of our customers, competitors or new market entrants develop algorithms or other AI tools capable of replicating or better competing against our services, our services and solutions could, over time, become obsolete or unnecessary, or the demand for our services could be significantly reduced, particularly if any such AI alternative proved to be more accurate, more efficient and/or more cost-effective than our employees. Any widespread automation of our TIC services could have a material adverse effect on our business, financial condition and results of operations. Further, the use of AI by our customers could lead to product designs which incorporate safety standards and requirements so completely that AI-designed products become the more trusted norm versus human-driven design, testing and inspection.

Technological advances in AI may in the future disrupt the S&A portion of the industry, which could significantly reduce the demand for our services or otherwise adversely impact our business or reputation if we are unable to successfully keep pace and navigate this evolving environment.

We use machine learning and AI technologies in our business, and we are making investments in expanding AI capabilities in our products, services and tools, including developing new product features using AI technologies. However, AI technologies are complex and rapidly evolving, and we face significant competition from other companies as well as an evolving regulatory landscape. The proliferation of new and emerging AI technologies, such as generative AI, in the S&A industry

14

may require additional investment in the development of proprietary datasets and machine learning models, new approaches and processes to provide attribution or remuneration to creators of training data and appropriate protections and safeguards for handling the use of customer data with AI technologies, which may be costly and could impact our expenses if we decide to expand AI technologies in our S&A product offerings. Ultimately, our failure to incorporate AI technologies in our product offerings in a timely, effective and compliant manner may place us at a competitive disadvantage, reducing demand for our offerings and adversely affecting our business results; however, there can be no assurance that the usage of or our investments in such technologies will always enhance our products or services or be beneficial to our business, including our efficiency or profitability.

The introduction of AI technologies into new or existing products may result in new or enhanced governmental or regulatory scrutiny, confidentiality or security risks, ethical concerns, legal liability or other complications that could adversely affect our business, reputation and financial results. For example, AI technologies incorporated into our product offerings may use algorithms, datasets or training methodologies that may be flawed or contain deficiencies that may be difficult to detect which, in turn, may create customer content that is factually inaccurate, biased or otherwise flawed. If our customers or others rely on or use such content to their detriment, it may lead to adverse outcomes, which may expose us or our customers to reputational harm, competitive harm or legal liability. Additionally, the use of certain AI technologies, including generative AI, may place our and our customers’ confidential information at risk if adequate security measures are not employed. Further, the intellectual property ownership and license rights, including copyright, surrounding AI technologies has not been fully addressed by U.S. courts or other federal or state laws or regulations, and the use or adoption of third-party AI technologies into our products and services may result in exposure to claims of copyright infringement or other intellectual property misappropriation.

The legislative, judicial and regulatory landscapes relating to AI are evolving and may impact our ability to use AI, and could limit our ability to operate and expand our business, cause revenue to decline and adversely affect our business. The actual or perceived failure to comply with regulatory requirements and laws relating to AI could result in significant liability or reputational harm.

Uncertainty in the legal regulatory regime relating to AI may require significant resources to modify and maintain business practices to comply with U.S. and non-U.S. laws, the nature of which cannot be determined at this time. Several jurisdictions around the globe, including Europe, China and certain U.S. states, have already proposed or enacted laws and regulations governing AI. For example, in the United States, an Executive Order was issued on the Safe, Secure and Trustworthy Development and Use of AI, emphasizing the need for transparency, accountability and fairness in the development and use of AI. The order seeks to balance fostering innovation with addressing risks associated with artificial intelligence by providing eight guiding principles and priorities, such as ensuring that consumers are protected from fraud, discrimination and privacy risks related to AI. The order also calls for future regulations from various agencies, such as the U.S. Federal Trade Commission (to ensure fair competition and reduce consumer harm) and, in alignment with the order, other agencies have published guidance, such as the Cybersecurity and Infrastructure Security Agency. In Europe, on August 1, 2024, the EU Artificial Intelligence Act (the “EU AI Act”) entered into force, and establishes a comprehensive, risk-based governance framework for AI in the EU market. The majority of the substantive requirements will apply from August 2, 2026. The EU AI Act applies to companies that develop, use and/or provide AI in the EU and – depending on the AI use case - includes requirements around transparency, conformity assessments and monitoring, risk assessments, human oversight, security, accuracy, general purpose AI and foundation models, and fines for breach.

In China, a number of regulations to govern AI have been implemented, namely the Interim Provisions on Management of Generative Artificial Intelligence Services, Administrative Provisions on Algorithm Recommendation for Internet Information Services and Provisions on Management of Deep Synthesis in Internet Information Service, respectively. Such regulations impose strict obligations on service providers, among other entities, with respect to their provision and use of generative AI, algorithmic recommendation and deep synthesis technologies. For example, service providers must file the algorithms used and complete a security assessment with the local CAC before the provision of the AI service. The regulatory framework in China is expected to have a material impact on the way AI is regulated in China, and together with developing guidance and/or decisions in this area, may affect our use of AI and our ability to provide and to improve our services. Other jurisdictions may decide to adopt similar or more restrictive legislation that may render the use of such technologies challenging.

Additionally, certain privacy laws extend rights to individuals (such as the right to delete certain personal data) and regulate automated decision making, which may be incompatible with our AI features or our use of AI. These obligations may lead to regulatory fines or penalties or prevent or limit our use of AI. If we are deemed to not have sufficient rights to the data we use to train our generative AI technologies, we may be subject to litigation by the owners of the content or other materials that comprise such data, similar to the litigation that is currently pending in various U.S. courts against other developers of

15

generative AI technologies, and in which the outcome of such litigation is uncertain. If we cannot use AI, or that use is restricted, our business may be less efficient, or we may be at a competitive disadvantage. We are implementing various initiatives that are designed to address potential AI risks; however, these initiatives may prove insufficient to mitigate potential risks.

A failure to effectively leverage emerging AI technology in our internal operations and management of our business may adversely impact the efficiency of our operations and our ability to keep pace with our competitors and may expose us to regulatory and other risks.

As machine learning and AI technology continues to evolve, more companies are leveraging these technologies to improve efficiencies and maximize opportunities with respect to the management of their respective businesses. We continue to evaluate the ability to leverage such technologies for our own internal operations, including, among other things, fuzzy searches, data extraction and content summarization. However, if we fail to effectively utilize and implement such technologies, or our utilization of such technologies is restricted as the regulatory environment around AI technologies evolves, our business may become less efficient or exposed to greater regulatory risk and may be at a competitive disadvantage. Further, the introduction of AI technologies into our operations may result in new or enhanced governmental or regulatory scrutiny, confidentiality (including placing our employees’ and our customers’ confidential information at risk) or security risks, ethical concerns, legal liability or other complications that could adversely affect our business, reputation and financial results.

The success of our business depends, in part, on our ability to develop new proprietary technical solutions, increase the functionality of our current solutions and develop our reputation as a technology leader.

Our success depends on our ability to continue to innovate, develop and introduce new software and techniques to support our services in order to continue to meet the requirements of our customers better than our competitors. If we fail to do so, or if a competitor develops equivalent or superior technology, demand for certain of our existing services could decline, we may not be able to take advantage of new market opportunities that may arise and we may be required to make significant unplanned occasional expenditures to develop technological solutions that will allow us to compete more effectively. Furthermore, if our competitors have greater resources and access to funding, they may be able to finance the development of new technologies before we are able to do so, which may allow them to enter new markets before us or provide lower-priced or better-quality services. The occurrence of any of the foregoing events could have a material adverse effect on our business, financial condition and results of operations.

Our business is highly competitive. If we fail to compete successfully, or if we fail to innovate in response to changing customer needs, new technologies or other market requirements, our business, financial condition and results of operations could be adversely affected.

We face competition from other providers of TIC and S&A services, as well as from new competitors such as start-ups and private equity-backed companies. We generally compete with them on the basis of quality, service, reputation, cost, capacity and turn-around time of our services and our reputation with third parties, such as retailers and regulators. If our services, supply, support, distribution, cost structure or reputation do not enable us to continue competing successfully with our current competitors, or to compete in the future with any new market entrants, our business, financial condition and results of operations could be materially adversely affected.

Our future success and competitive advantage also depend on our ability to keep pace with rapid technological changes that could make our services less competitive or obsolete and on our ability to increase customer adoption of our services, including our SaaS offerings. Our customers are continuously innovating their products and technology and generally expect us to keep pace with their innovations. We risk losing market share if we fail to adapt quickly enough to market needs in areas like AI, embedded software, functional safety and other new technologies as they evolve. Our competitors or others might develop technologies or services that are more effective or commercially attractive than our current or future offerings, or that render our technologies or services obsolete. Our competitors may also monetize their data solutions more quickly or effectively than us. If we fail to successfully monetize our data or data-based offerings, invest in the right technologies or innovate as technology and our customers’ needs evolve, or if our competitors introduce superior technologies or services and we cannot make enhancements to our own, our competitive position and, in turn, our business, financial condition and results of operations could be materially and adversely affected. Many of the markets in which we compete, including cybersecurity and connected devices, are also subject to evolving industry and information technology (“IT”) operational standards and regulations, resulting in increasing compliance requirements for us and our customers. To the extent we expand further into highly regulated industries, our services may need to address additional requirements specific to those industries.

16

In addition, our ability to compete may be affected by increased digital disruption of the TIC industry by evolving technology and new solutions. The TIC industry is subject to increasingly rapid technological changes, including an increased focus on data provisioning and analysis. For example, increased digitization of regulatory or product information, simulation and predictive testing of products, remote inspection or reliance on AI could replace traditional TIC services. Our failure to innovate and adapt to address these changes, either on a timely basis or at all, could result in our loss of market share or significantly reduce demand for our services.

Finally, remaining competitive in our industry requires us to maintain a favorable geographic dispersion. If our geographic placement and dispersion are, or become, suboptimal, or our competitors are able to achieve more favorable geographic dispersion, whether through organic or inorganic growth, we could lose or miss out on market share. Additionally, we compete with a number of local and regional TIC service providers who may be better suited than us to compete in local and regional markets due to their brand recognition, expertise in local and regional regulations and better access to local and regional markets and customers. If we cannot adapt or meet the needs of our customers in the various regions in which we and our customers are located, we may not be able to continue to compete successfully on a global scale.

We are subject to a variety of risks associated with doing business outside the United States.

We maintain significant international operations, including operations in Greater China (mainland China, Hong Kong and Taiwan), Japan, Germany, the Republic of Korea, Italy and Canada, as well as other countries. We continue to increase our global footprint. For example, since 2022, we have opened additional laboratories in Mexico, the Republic of Korea, Vietnam and Taiwan. In 2024, approximately 59.0% of our revenue was generated from customers outside the United States. As a result, we are subject to a number of risks and complications associated with international sales, services and other operations, as well as risks associated with U.S. foreign policy. These include:

•difficulties associated with compliance with numerous, potentially conflicting and frequently complex and changing laws and regulations in multiple jurisdictions, such as with respect to business licensing and environmental matters, intellectual property, privacy and data protection, corrupt practices, embargoes, trade sanctions, competition, employment and licensing;

•general economic, social and political conditions in countries where we operate, including international and U.S. trade policies, currency exchange rate fluctuations and political instability;

•tax and other laws that reduce our profitability or restrict our ability to use tax credits, offset gains or repatriate funds, as well as changes in local and international tax laws, including transfer pricing regulations and changes in tax treaties, which may restrict our ability to use tax credits, offset gains, repatriate funds or result in adverse tax consequences;

•any adverse changes in the regulatory environments applicable to us, which could negatively impact our business;

•foreign exchange and currency restrictions, transfer pricing regulations and adverse tax consequences, which may affect our ability to transfer capital and profits;

•inflation, deflation and stagflation in any country in which we have operations;

•foreign customers with longer payment cycles than customers in the United States; and

•imposition of or increases in customs duties and other tariffs.

Further, we operate in a number of countries throughout the world, including in countries that lack developed legal systems or do not have as strong a commitment to anti-corruption and ethical behavior as is required by U.S. laws or by our corporate policies. In addition, based on the nature of our services and our structure, we deal with both governments and government-owned business enterprises, such as our 70% joint venture interest in UL-CCIC Company Limited (“UL-CCIC”). Therefore, we are subject to the risk that we, our officers, directors, employees, business partners, joint venture partners or any third party that we engage to do work on our behalf may take action determined to be in violation of anti-corruption laws in the jurisdictions in which we conduct business, including the U.S. Foreign Corrupt Practices Act (the “FCPA”), the UK Bribery Act 2010 (the “Bribery Act”) and the Canadian Corruption of Foreign Public Officials Act (the “CFPOA”), which prohibit corruptly providing, offering, promising or authorizing, directly or indirectly, anything of value to foreign officials, political parties or candidates for political office for the purposes of obtaining or retaining business or securing any improper business advantage. The provisions of the Bribery Act also prohibit non-governmental commercial bribery, soliciting or accepting

17

bribes and “facilitation payments,” or small payments to low-level government officials to expedite routine approvals. The Bribery Act also has an offense applicable to corporate entities and partnerships that carry on part of their business in the United Kingdom that fail to prevent bribery, which can take place anywhere in the world, by persons who perform services for or on behalf of them, subject to a defense of having adequate procedures in place to prevent the bribery from occurring. The offense could render parties criminally liable for the acts of their agents, joint venture partners or commercial partners, even if done without their knowledge.

Any violation of the FCPA, the CFPOA, the Bribery Act or any similar anti-corruption law or regulation could result in substantial fines, sanctions, disgorgement of profits or civil or criminal penalties, debarment from business dealings with certain governments or government agencies or restrictions on the marketing of our services in certain countries, injunctions or other remedial measures, which could harm our business, financial condition and results of operations. If these anti-corruption laws or our internal policies were to be violated, our reputation and operations could also be substantially harmed. Further, detecting, investigating and resolving actual or alleged violations is expensive and can consume significant time and attention of our senior management.

Compliance with multiple, and potentially conflicting, international laws and regulations, including anti-corruption laws, may be difficult, burdensome or expensive. U.S. public companies are required to maintain records that accurately and fairly represent their transactions and have an adequate system of internal accounting controls. We maintain internal controls, policies and procedures to promote compliance by our directors, officers, employees or business partners and third parties acting on our behalf with the FCPA, the Bribery Act, the CFPOA and other applicable anti-corruption laws. However, we can make no assurance that our controls, policies and procedures, even if enhanced, have been or will be followed at all times or will effectively detect and prevent all violations of the applicable laws. Further, in connection with past and future acquisitions by us, there is a risk of successor liability relating to such laws in connection with prior actions or alleged actions of an acquired company. Such matters or allegations related to such matters could adversely affect our reputation and the burden and cost associated with defending or resolving such matters could adversely affect our business, prospects, financial condition and results of operations.

Although we currently operate in a number of countries throughout the world, a shift in the location of our customers’ product development and manufacturing could result in us needing to expand into, and compete in, new jurisdictions and, as a result, to navigate new regulatory and competitive environments.

We may be adversely affected by global and regional economic and political instability.

We may be adversely affected by global and regional economic and political conditions. The uncertainty or deterioration of the global economic and political environment could adversely affect us. Customers may modify, delay or cancel plans to purchase our services. Any inability of current or potential customers to purchase or pay for our services due to, among other things, declining economic conditions as a result of inflation, rising interest rates, changes in spending patterns and the effects of governmental initiatives to manage economic conditions may have a negative impact on our business, prospects, financial condition and results of operations. Additionally, we may face uncertainties in the business environment or volatility in financial markets due to policy shifts of changing administrations in certain key markets. For example, following the 2024 U.S. presidential and congressional elections there may be increased uncertainty and volatility in the global economy and financial markets created by anticipated shifts in U.S. and foreign trade, economic and other policies. Overall demand for our services could be reduced as a result of a global financial crisis, economic recession or political unrest.

For example, the conflicts between Russia and Ukraine and in Israel, Gaza and surrounding areas have created increasingly volatile geopolitical and economic conditions around the world; however, we do not currently expect that either conflict will have a material, direct impact on our business. In March of 2022, we made the decision to stop all work in Russia and Belarus and not take on or pursue any new customer orders related to those countries for the foreseeable future. However, geopolitical instability and adversity arising from such conflicts (including additional conflicts that could arise elsewhere in the world), the imposition of sanctions, taxes or tariffs against Russia and Russia’s response (including retaliatory acts, such as cyber-attacks and sanctions against other countries) and impacts to energy markets and supplies could adversely affect the global economy or specific international, regional and domestic markets we operate in, increase inflationary pressures, or disrupt our customers’ supply chains, which could in turn have a material adverse effect on our business and financial condition.

Additionally, our operating cash flows, combined with access to the credit markets, provide us with significant discretionary funding capacity. However, deterioration in the global credit markets may limit our ability to access credit markets, which could adversely affect our liquidity or increase our cost of borrowing. Increases in our cost of borrowing could adversely affect our liquidity and results of operations.

18

Enhanced trade tariffs, import restrictions, export restrictions, regulations of mainland China or other trade barriers could materially adversely affect our business.

We are continuing to expand our international operations as part of our growth strategy and have experienced an increasing concentration of sales in certain regions outside the United States. There is currently significant uncertainty about the future relationship between the United States and various other countries, most significantly mainland China, with respect to trade policies, treaties, government regulations and tariffs. Tariffs, trade restrictions or trade barriers that have been, and may in the future be, placed on products we test, inspect and certify by foreign governments, especially mainland China, have raised, and could further raise, amounts paid for some or all of our services, which may result in the loss of customers and our business, and our financial condition and results of operations may be harmed. Further tariffs may be imposed that could cover imports of components and materials used in our customers’ products, or our business may be adversely impacted by retaliatory trade measures taken by mainland China or other countries, including restricted access to components or materials used in our customers’ products or increased amounts that must be paid for their products, which could significantly reduce demand for our services, in turn materially harming our business, financial condition and results of operations. Further, the continued threats of tariffs, trade restrictions and trade barriers could have a generally disruptive impact on the global economy and, therefore, negatively impact our sales. Given the relatively fluid regulatory environment in China and the United States and uncertainty regarding how the U.S. or foreign governments will act with respect to tariffs, international trade agreements and policies, there could be additional tax or other regulatory changes in the future. Any such changes could directly and adversely impact our financial results and results of operations. For a discussion of additional risks related to our business in China, see “—Risks Related to Conducting Business in China.”

We are subject to governmental export and import controls that could impair our ability to compete in international markets or subject us to liability if we violate the controls.

Our business is subject to U.S. export controls, including the U.S. Export Administration Regulations. Obtaining the necessary export license or other authorization for a particular sale may be time-consuming and may result in the delay or loss of sales opportunities. Furthermore, our activities are subject to U.S. economic sanctions laws and regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Control that prohibit the sale or supply of most products and services to embargoed jurisdictions or sanctioned parties. Violations of U.S. sanctions or export control regulations can result in significant fines or penalties and possible incarceration for responsible employees and managers. If we fail to obtain appropriate import, export or re-export licenses or permits, we may be adversely affected through reputational harm, as well as other negative consequences, including government investigations and penalties.

Also, various countries, in addition to the United States, regulate the import and export of certain technology, including import and export licensing requirements, and have enacted laws that could limit our ability to distribute our SaaS and other technology solutions in those countries. Future changes in export and import regulations may create delays in the introduction of our technology solutions in international markets. Any change in export or import regulations, economic sanctions or related legislation, increased export and import controls or change in the countries, governments, persons or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. Any decreased use of our technology solutions or limitation on our ability to export or sell our technology solutions could adversely affect our business, financial condition and results of operations.

The success of our operations in international markets is highly dependent on the expertise of local management and operating staff, as well as the political, social, legal and economic operating conditions of each country in which we operate.

The success of our business depends on the actions of our employees. In our international locations, we are highly dependent on our local management and operating staff to serve our customers and operate our facilities in these markets in accordance with local law and best practices. If the local management or operating staff were to leave our employment, we would have to expend significant time and resources building up our management or operational expertise in these local markets. Such a transition could adversely affect our reputation in these markets and could materially and adversely affect our business and operating results.

Additionally, the health and safety of our employees or those working on our behalf, and the security of our physical infrastructure, may be affected due to acts of violence or vandalism by anti-social elements. Although we take protective measures to ensure the safety of our employees at our global locations of work and transit, incidents of organized political demonstrations, civil unrest or random acts of rage can affect the safety of our assets and employees, impacting our business and operating results.

19

We are also subject to other inherent risks attributed to operating in a global economy. As of December 31, 2024, we leased or owned 91 sites with laboratories spread across 26 countries. If the international markets in which we compete are affected by changes in political, social, legal, economic or other factors—such as deterioration in U.S.-China relations, instability in the North Korean peninsula or South China Sea, the conflict between Russia and Ukraine or the conflict in Israel, Gaza and surrounding areas—our business and operating results may be materially and adversely affected. Uncertainty as a result of such changes may last for years and could also impact our customers’ businesses and operations. Our international operations may subject us to additional risks that differ in each country in which we operate and such risks may negatively affect our results.

Our senior leadership team is critical to our continued success, and the loss of such personnel could have a material adverse effect on our business, financial condition and results of operations.

Our current and future success depend substantially on the continued service and performance of the members of our senior leadership team. These personnel possess business and technical capabilities that are difficult to replace. We have attempted to mitigate this risk by providing what we view as market compensation and benefits, as well as appropriate retention incentives, including long-term incentive compensation with multi-year vesting provisions intended to incentivize and retain these key personnel. If we lose key members of our senior management operating team or are unable to effect smooth transitions from one executive to another as part of our succession plan, we may not be able to effectively manage our current operations or meet ongoing and future business challenges, and this could have a material adverse effect on our business, financial condition and results of operations.

Additionally, successfully executing organizational change, including management transitions and succession plans for our senior leadership, is critical to our business success. Although we have implemented disciplined, ongoing succession planning for our senior leadership and other key executives, this process does not guarantee that the services of qualified senior executives will continue to be available to us in the future.

Our success depends upon our ability to recruit, train and retain key employees—in particular, our technical personnel—including through the implementation of diversity and inclusivity initiatives.

Our current and future success depend substantially on our employees, including highly trained and skilled engineering, technical and professional personnel. We depend on the technical and regulatory know-how of our skilled and technical personnel, and competition for their talent is intense among our competitors. Particularly in highly specialized and technical areas, it has become more difficult to retain employees and meet all of our needs for employees in a timely manner, which could affect our growth. Although we intend to continue to devote significant resources to recruiting, training and retaining qualified employees—in particular, our technical talent—we may not be able to attract, effectively train and retain these employees. Any failure to do so could impair our ability to efficiently perform our contractual obligations, timely meet our customers’ needs and ultimately win new business, all of which could adversely affect our business, financial condition and results of operations.

In particular, the success of our TIC business relies on an adequate supply of skilled engineers. Trained and experienced technical personnel are in high demand and may be in short supply in some areas. We cannot guarantee that we will be able to recruit, attract and retain the skilled workforce of engineers necessary to continue offering our existing and future services widely or efficiently, or that labor expenses or employee turnover will not increase as a result of a shortage in the supply of skilled engineers, any of which could have a material adverse effect on our business, financial condition and results of operations.

Additionally, changes in immigration laws and policies have, in certain circumstances, made it more difficult—and may continue to make it more difficult—for us to recruit or relocate highly skilled technical, professional and management personnel to meet our business needs.

We are also working to promote our talent management efforts through the implementation of diversity and inclusivity initiatives throughout our organization. However, there has been increasing scrutiny about such initiatives, including from activists and policymakers challenging how such initiatives comply with civil rights protections. This may require us to incur additional costs to respond and monitor, and if we do not (or are perceived not to) successfully implement our initiatives, including in keeping with current or potential future laws or interpretations thereof, our ability to recruit, attract and retain talent may be adversely impacted.

20

Our profitability could suffer if we are not able to timely and effectively utilize our employees or manage our cost structure.

The cost of providing our services, including the degree to which our employees are utilized, affects our profitability. The degree to which we are able to utilize our employees in a timely manner or at all is affected by a number of factors, including:

•our ability to hire, assimilate and deploy new employees;

•our ability to forecast demand for our services and to maintain and deploy headcount that is aligned with demand, including employees with the right mix of skills and experience;

•our employees’ inability to obtain or retain required certifications;

•our ability to manage attrition; and

•our need to devote time and resources to training, business development and other non-chargeable activities.

Our greatest assets are our employees, and it is important that we spend adequate resources on their continued technical and regulatory training. If our employees are under-utilized, our profit margin and profitability could suffer. If our employees are over-utilized, it could have a material adverse effect on employee morale and attrition, which would, in turn, have a material adverse effect on our business, financial condition and results of operations.

Our profitability is also affected by the extent to which we are able to effectively manage our overall cost structure for operating expenses, such as wages and benefits, real estate expenses, overhead and capital, including our test equipment and its maintenance, and other investment-related expenditures. If we are unable to effectively manage our costs and expenses and achieve efficiencies, our competitiveness and profitability may be adversely affected.

We work with dangerous materials and in dangerous environments that could injure our employees, contractors or visiting customers, damage our or our customers’ facilities and disrupt our or our customers’ operations.

Some of our operations involve destructive testing and the handling of hazardous materials that may pose the risk of fire, explosion, human exposure to hazardous substances or the release of hazardous substances into the environment. For example, as part of our process for certifying a number of products, we use flammable materials and conduct fire testing, such as by setting houses on fire in our large-scale fire laboratories. We also recently opened battery testing laboratories where we test lithium ion batteries that contain potentially explosive materials, including our new battery testing laboratory in Auburn Hills, Michigan. Such events could result from the actions of our employees, operational failures, natural disasters or terrorist attacks, and might cause injury or loss of life to our employees and others, environmental contamination and property damage. Additionally, as discussed elsewhere in this Annual Report, much of our work, including the work we complete using dangerous materials or in dangerous environments, requires certain permits and other permissions. There is a risk that we, or any of the third parties who complete work for us or are permitted to use a portion of any of our laboratories, fail to obtain or maintain the requisite permits or permissions, on time or at all. Failure to properly handle, transport or dispose of these materials or otherwise conduct our operations in accordance with EHS or other applicable laws or requirements, or any injury or property damage caused by our employees at our or our customers’ facilities, could expose us to substantial liability for administrative, civil and criminal penalties, cleanup and site restoration costs and liability associated with releases of such materials, damages to natural resources and other damages, as well as potentially impair our ability to conduct our operations. Such liability is commonly on a strict, joint and several liability basis, without regard to fault. Liability may be imposed as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, prior operators or other third parties. Neighboring landowners and other third parties may file claims against us for personal injury or property damage allegedly caused by the release of pollutants into the environment. A disruption of our operations caused by these or other events could have a material adverse effect on our results of operations.

We are subject to risks related to sustainability and corporate social responsibility.

Our business faces increasing scrutiny related to ESG issues, including renewable resources, environmental stewardship, supply chain management and sustainable procurement, climate change, biodiversity and sustainable land use, air quality, safety, diversity and inclusion, energy use and emissions, waste, water use, workplace conduct, human rights, philanthropy and support for local communities. Increased expectations and increased regulations regarding such issues may result in increased costs (including, but not limited to, increased costs related to compliance, stakeholder engagement, contracting and

21

insurance), changes in demand for certain products, enhanced compliance or disclosure obligations or other impacts to our business, financial condition or results of operations.

While we may at times engage in voluntary initiatives (such as voluntary disclosures, certifications or goals, among others) to improve the ESG profile of our Company or to respond to stakeholder expectations, such initiatives may be costly and may not have the desired effect. Expectations around our management of ESG matters continue to evolve rapidly, in many instances due to factors that are out of our control. For example, we may ultimately be unable to complete certain initiatives or targets, either on the timelines initially announced or at all, due to technological, cost or other constraints that may be out of our control. Moreover, actions or statements that we may take based on expectations, assumptions or third party information that we currently believe to be reasonable may subsequently be determined to be erroneous or be subject to misinterpretation. If we fail, or are perceived to fail, to meet applicable standards or expectations with respect to these issues across all of our services and in all of our operations and activities, including the expectations we set for ourselves, our reputation and brand image could be damaged, we could be subject to negative allegations made by certain stakeholders and/or litigation and our business, financial condition and results of operations could be adversely impacted. For example, as stakeholder perceptions of sustainability continue to evolve, there have been increasing allegations of greenwashing against companies making significant ESG claims due to a variety of perceived deficiencies in performance.

Certain organizations that provide corporate governance and other corporate risk information to investors and stockholders have developed, and others may in the future develop, scores and ratings to evaluate companies and investment funds based on ESG or sustainability metrics. Many investment funds focus on positive ESG business practices and sustainability scores when making investments and may consider a company’s ESG or sustainability scores as a reputational or other factor in making an investment decision. In addition, investors, particularly institutional investors, use these scores to benchmark companies against their peers and if a company is perceived as lagging, these investors may engage with such companies to improve ESG disclosure or performance and may also make voting decisions, or take other actions, to hold these companies and their boards of directors accountable. This may require us to incur significant additional costs or negatively impact our share price or access to and cost of capital. Similarly, to the extent ESG matters negatively impact our reputation, it may also impede our ability to compete as effectively to attract and retain employees or customers, which may adversely impact our operations. Certain of our customers also have their own ESG requirements, which are subject to change, and any failure to meet such requirements may adversely impact our ability to do business with them. We may be especially subject to scrutiny on such matters given our efforts to portray our operations and services as a tool to help assess and manage certain ESG risk.

In addition, we expect there will likely be increasing levels of regulation, disclosure-related and otherwise, with respect to ESG matters. For example, various policymakers (including the SEC, the EU and the State of California) have adopted and may, in the future, further adopt requirements for climate- or other ESG-related disclosures. These requirements are not uniform across jurisdictions, and may be inconsistently applied, which can increase the complexity and cost of compliance, and increase the risk of enforcement or litigation relating to our ESG disclosures and initiatives. While certain of these requirements are limited to listed companies, others (such as several laws adopted in California and the EU) apply to companies that meet certain operational thresholds. These requirements and evolving other stakeholder expectations will likely lead to increased costs, as well as scrutiny that could heighten all of the risks identified in this risk factor. Additionally, many of our customers, business partners and suppliers may be subject to similar expectations, which may augment our existing risks or create new risks, including risks that may not be known to us.

Public perceptions that the products we use or the services we use and deliver are not environmentally friendly, environmentally safe or ethical could adversely impact the demand for our services and our results of operations.

Public perception that the products we use or services we use and deliver are not environmentally friendly or safe or that they are harmful to humans or animals, whether justified or not, could reduce demand for our services, increase regulation or government restrictions or actions, result in fines or penalties, impair our reputation, involve us in litigation, damage our brand reputation and otherwise have a material adverse impact on our business, financial position, results of operations and cash flows. For example, we contract with companies that conduct testing on animals. If such companies fail to comply with the Animal Welfare Act or other laws and regulations governing the treatment of animals used in research, we could be subject to fines, penalties or adverse publicity, and our results of operations could be adversely affected.

A conflict of interest or perceived conflict of interest between our testing, inspection or certification services, on the one hand, and our advisory and other services, on the other hand, could adversely impact our accreditations or our reputation or expose us to legal liability.

Through our advisory services, we provide sustainability, quality, risk management and other solutions for our customers’ products and their product development, supply chains and organizations, as well as regulatory market access services.

22

Conflicts of interest may arise where we provide certain advisory services or solutions for products or customers to which we are also providing testing, inspection or certification services. To maintain certain of our accreditations, we must meet applicable impartiality standards that govern these conflicts of interest. For example, ISO 17065 prohibits a certification body and any part of the same legal entity from being the designer, manufacturer, installer, distributor, implementer, provider or maintainer of a certified product, process or service. Although we have systems in place designed to ensure compliance with ISO 17065 and other impartiality requirements, such conflicts of interest, or a perceived conflict of interest, between our testing, inspection or certification services and our advisory services could impact our accreditations. Meeting the applicable impartiality requirements may require expending significant resources to implement operating firewalls and otherwise comply. Costs to comply are exacerbated by the fact that various accreditors around the world have offered differing interpretations of the standards governing impartiality and conflicts of interest. If our testing, inspection or certification services are determined not to meet the necessary impartiality standards due to our simultaneous advisory offerings, we could lose our accreditations (e.g., ISO 17025, ISO 17020, ISO 17065) or be forced to divest conflicting businesses. Our reputation could also be harmed, and we could be exposed to significant liability. If any of the foregoing events occur, it would likely have a material adverse effect on our business, financial condition and results of operations.

Adverse changes to applicable regulatory frameworks or an increase in the acceptance of self-declaration of conformity that results in a corresponding decrease in third-party certification could reduce demand for our TIC services, which could have a material adverse effect on our business, financial condition and results of operations.

Our business is primarily driven by private sector requirements and government regulations that currently require independent third-party testing and certification of a significant number of products. For example, much of the demand for third-party certification of professionally installed products, including lighting, HVAC, building materials and electrical cable and products—which make up a significant portion of our TIC revenue—is driven primarily by state and local governments as enforced through the use of model codes. In addition, many large retailers currently require that the products they sell be third-party certified, and AHJs demand certification of certain products as well. Any significant adverse change to any regulations governing TIC services, or any significant adverse change in private sector preferences or demands, could have a material adverse effect on our business, financial condition and results of operations.

Additionally, the regulatory regime for TIC services varies by country and product type. For example, some countries allow for self-declaration of conformity to applicable requirements for certain products. If regulations in the United States or other countries are changed, including, for example, as a result of enhanced judicial scrutiny of federal regulatory regimes following the overturning of the Chevron doctrine in the U.S. Supreme Court’s decision in Loper Bright Enterprises v. Raimondo, to allow for additional self-declaration, or if large retailers were to start accepting self-declared products, the need for third-party certifications could decrease over time, thus reducing demand for our TIC services. A substantial increase in the self-declaration of conformity and any corresponding decreased demand for our TIC services would likely have a material adverse effect on our business, financial condition and results of operations.

Our operations are subject to a variety of business continuity hazards and risks—for example, pandemics, epidemics and other health crises or our reliance on the use of materials and services from a few locations or suppliers—any of which could interrupt our business operations or otherwise adversely affect our financial condition and results of operations.

Our operations, and the operations of our vendors and service providers, are subject to business continuity hazards and risks that include explosions, fires, earthquakes, inclement weather and other natural disasters; utility or other mechanical failures; labor difficulties or other workforce disruptions; disruption of our communications; terrorist attacks; security breaches; and pandemics, epidemics or other public health crises.

For example, although the COVID-19 pandemic did not have a material effect on our financial results, challenging market conditions resulting from COVID-19 did have an adverse effect on many of our customers. Any resurgence or emergence of additional variants, or the global outbreak of any new pandemic or contagious disease, may in the future have, negative impacts on our business, including, but not limited to reductions in our laboratory capacities and increased costs and protective measures with respect to the health and safety of employees working in our laboratories, a decline in customer demand, delays in the delivery of certain products and equipment we use internally and of customer samples to our laboratories, as a result of global supply chain disruptions, excess turnover among our employees and postponed or canceled planned investments in response to changes in our business. We cannot predict the future impacts of the COVID-19 pandemic or any new pandemic, epidemic or global health crisis on our business, and such future impacts could have a material adverse effect on our financial condition and results of operations.

As another example, the sale of labels bearing the UL Mark is material to our certification business, and we currently fulfill label orders submitted to us through one supplier in the United States. Although we have identified alternate third parties to

23

provide this service, we cannot guarantee we would be able to contract with such alternate third parties within a reasonable amount of time or at all, or upon similar pricing and volume terms, nor can we be assured that any such third party would be capable of producing our labels in sufficient volume and quality. Any event, including those listed above, other circumstances that result in a prolonged business disruption or shutdown to one or more of their facilities, or the facilities of our other vendors and service providers, or a deterioration in our relationship with them, or any of our other vendors or service providers, in each case, could create conditions that prevent, or significantly and adversely affect, our sales, increase our expenses, create potential liabilities or damage our reputation, any of which could have an adverse effect on our business, financial condition and results of operations.

If we are unable to increase capacity at our existing facilities or build new facilities in a timely and cost-effective manner, we may not achieve our expected revenue growth or profitability or such revenue growth and profitability, if any, could be delayed.

Our growth strategy depends on expanding our capacity, which may include building new facilities and expanding our existing facilities. For example, since 2022, we have opened new laboratories in Mexico, Vietnam, Taiwan, the Republic of Korea and the United States (including the opening of our Retail Center of Excellence in Arkansas) and have expanded our laboratories in China, and we are in the process of constructing new laboratories in Italy, China, Singapore and the United States and expanding laboratories in the United States, Germany and China. The construction or expansion of modern and safe facilities requires significant expenditures. Delays in construction of such facilities, or in the review and licensing process for any new facility, could impair or delay our ability to develop that facility or increase the cost so substantially that the facility becomes unattractive to us. Any failure to procure and maintain the necessary licenses would adversely affect ongoing development, construction and continuing operation of our facilities. Additionally, even when we maintain the necessary licenses and are in compliance with applicable regulations, we may be unable to maintain or expand our operations at existing facilities, or otherwise execute on our growth strategy, due to negative publicity or resistance from non-governmental organizations or local communities. Suspensions and closures of our facilities could materially impact our results of operations. Any new facilities that are constructed and begin operations may not meet our return expectations due to schedule delays, cost overruns or revenue shortfalls, or they may not generate the capacity that we anticipate or result in the receipt of revenue in the originally anticipated time period, or at all. For example, we have experienced, and may continue to experience in the future, laboratory equipment shortages as a result of global supply chain disruptions. We may not maintain revenue growth or profitability, or such growth, if any, could be delayed if we are not successful in continuing to expand our capacity. Additionally, if future demand trends warrant capacity in geographic areas that we have not targeted for new growth, we may be unable to capitalize on opportunities in a timely manner.

Our failure to meet contractual schedule requirements, meet a required performance standard, meet our internal contractual performance projections or otherwise perform adequately on a project could adversely affect our business, financial condition and results of operations.

Under some of our agreements, we can incur liquidated or other damages if we do not achieve project completion by a scheduled date. In addition, our costs generally increase from schedule delays and could exceed our projections for a particular project. Project performance can be affected by a number of factors beyond our control, including unavoidable delays from governmental inaction, inability to obtain financing, weather conditions, unavailability of materials or site inaccessibility, changes in the project scope of services requested by our customers, industrial accidents, environmental hazards, labor disruptions and other factors. Any defects or errors, or failures to meet our customers’ expectations, in our projects or services could result in claims for damages against us and could adversely affect our reputation. Material performance problems for existing and future agreements could cause actual results of operations to differ from anticipated results of operations and could cause us to suffer damage to our reputation within our industries and among our customers.

For certain of our services, we face a long selling cycle to secure new agreements, and securing such agreements often requires significant resource commitments, which result in long lead times before we receive revenues from new relationships.

For the majority of our services, our selling cycle is managed by our sales teams and represents the time from initial contact to signed agreement. This type of sale is usually completed between one week and two months in most service areas. However, in some of our service areas, our selling cycle can also involve becoming an approved supplier for third-party services. Doing so is a business development process that can take between six months and one year, depending on the service, resulting in what we consider a long selling cycle. We occasionally incur significant business development expenses, and expend significant resources, during a longer selling cycle, and we may not succeed in winning a new customer’s business, in which case we receive no revenues and may receive no reimbursement for such expenses. Even if we succeed in developing a relationship with a potential new customer, we may not be successful in obtaining contractual commitments

24

after the selling cycle or in maintaining contractual commitments after the implementation cycle, which may have an adverse effect on our business, results of operations and financial condition.

The growth of our business may be adversely affected if we do not implement our growth strategies and initiatives successfully or if we are unable to manage our growth or operations effectively.

We have expanded, and are continuing to expand, our operations, suite of services and customer relationships, which has placed, and will continue to place, significant demands on our management and our operational, IT and financial infrastructures. Additionally, our ability to grow in the future will depend on a number of factors, including our ability to develop and expand new and existing customer relationships, continue providing and expanding the services we offer, hire and train qualified personnel, grow in existing markets and expand into new or future markets, develop and operationalize new service offerings and sustain operational excellence and efficiencies across our business lines. Achieving and sustaining growth requires the successful execution of our growth strategies, which may require the implementation of enhancements to customer-facing, operational and financial systems, expanded sales and marketing capacity, continuous updates to technology and improvements to processes and systems and additional or new organizational resources. Given these challenges, we may be unable to manage our expanding operations effectively, or to maintain our growth, which could have a material adverse effect on our business, financial condition and results of operations.

Part of our growth strategy is to pursue strategic transactions, including acquisitions, and we may not be able to find suitable acquisition targets or achieve our desired acquisition objectives.

As part of our strategy, we have in the past and plan in the future to seek to grow our business through acquisitions, and any such acquisition may be significant. Any future growth through acquisitions will depend in part upon the continued availability of suitable acquisition candidates at favorable prices and upon advantageous terms and conditions, which may not be available to us, as well as sufficient funds from our cash on hand, cash flow from operations, existing debt facilities and additional indebtedness to fund these acquisitions.

Not only is the identification of such suitable acquisition candidates difficult and competitive, but these transactions, including the acquisitions completed in recent years, also involve numerous risks, including the diversion of management’s attention and their ability to:

•successfully integrate acquired facilities, companies, products, systems or personnel into our existing business;

•minimize any potential interruption to our ongoing business;

•successfully enter categories and markets in which we may have limited or no prior experience;

•achieve expected synergies and obtain the desired financial or strategic benefits;

•detect and address any financial or control deficiencies of the acquired company;

•retain key relationships with founders, management and other employees, contractors, customers, partners, accreditors and suppliers of acquired companies, as well as our own management, employees, contractors, customers, partners and suppliers; and

•maintain uniform compliance standards, controls, procedures and policies throughout acquired companies.

Companies, businesses or operations acquired or joint ventures created may not be profitable or may not achieve revenue and profitability levels that would justify the investments made. Recent and future acquisitions could also result in the incurrence of indebtedness, subject to the restrictions contained in the documents governing our then-existing indebtedness.

Recent and future acquisitions could also result in the assumption of contingent liabilities, litigation risk, unfavorable commercial contract or lease terms, material expenses related to certain intangible assets, environmental liabilities, increased operating expenses and compliance issues under international laws and regulations, including anti-trust laws, sanctions laws, labor laws, anti-corruption laws, the FCPA and similar anti-bribery laws, which could adversely affect our business, prospects, financial condition and results of operations. In addition, to the extent that the economic benefits associated with any of our acquisitions diminish in the future, we may be required to record additional write-downs of goodwill, intangible assets or other assets associated with such acquisitions, which could adversely affect our business, prospects, financial condition and results of operations. Our ability to realize the benefits we anticipate from our strategic transactions, including

25

acquisition activities, anticipated cost savings and additional sales opportunities, will largely depend upon whether we are able to integrate such businesses efficiently and effectively. If we are unable to successfully integrate the operations of acquired businesses into our business or on the timeline we expect, we may be unable to realize the sales growth, cost synergies and other anticipated benefits we expect to achieve as a result of such transactions and our business, prospects, financial condition and results of operations could be adversely affected.

Pursuant to our Amended Charter and the Stockholder Agreement, until UL Standards & Engagement no longer beneficially owns at least 25% of the voting power of our then-outstanding voting stock, neither we nor any of our subsidiaries is permitted to, without the prior written consent of UL Standards & Engagement, among other things, (1) enter into any new material line of business, excluding TIC and S&A activities, (2) merge or consolidate with or into another entity, other than in connection with an internal restructuring or reorganization or any strategic transaction we undertake in the course of our business that does not exceed 15% of our equity market capitalization, in each case except where there is no change to the relative ownership or voting percentages of our stockholders or any other rights, (3) acquire stock or assets or enter into joint ventures involving consideration or obligations exceeding 15% of our equity market capitalization, (4) issue securities (i) at a price below fair market value, other than an underwritten public offering for cash, (ii) with rights that are senior to the rights of the holders of our Class B common stock, (iii) that would result in dilution of greater than 10% of our then-outstanding common stock, or (iv) that would result in UL Standards & Engagement beneficially owning less than a majority of our then-outstanding securities, or (5) incur indebtedness for borrowed money that would cause a downgrade of our debt securities from any of Moody’s Investor Service, Inc., Standard & Poor’s Ratings Group and Fitch Ratings, Inc. (collectively, the “Rating Agencies”) below investment grade.

We cannot guarantee that UL Standards & Engagement will exercise its consent rights in a way that aligns with the interests of our other stockholders. UL Standards & Engagement’s interests may not be the same as, or may conflict with, the interests of our other stockholders. Actions that UL Standards & Engagement takes with respect to us, as a controlling or significant stockholder, may not be favorable to us or our other stockholders. For example, if UL Standards & Engagement exercises its consent rights in a way that prevents us from taking advantage of business or strategic opportunities, our business, financial position, results of operations and cash flows may be adversely impacted.

We operate across a number of industries that have inherent safety risks.

We provide TIC services to companies across a number of industries with a variety of inherent safety risks, such as the energy and utilities, buildings and construction, chemicals and materials and healthcare and life sciences industries. Such safety risks can give rise to serious and potentially catastrophic environmental or technological incidents. Our customers use our TIC services to assess their products, facilities, processes, components and systems. The results of such services may be incorrect or incomplete, whether as a result of poorly designed or flawed tests or inspections, malfunctioning testing equipment, the failure of our employees to adequately perform testing or properly record data or otherwise. If an accident or incident occurs involving products, facilities, processes, components or systems that we tested, inspected or certified, and causes personal injuries or property damage, particularly if the injuries or damage could have been prevented by correct or complete results, we may be subject to negligence or other legal claims or suffer damage to our reputation and, as a result, lose existing or future agreements with customers. In addition, any investigation into or claim related to such an incident could take a significant period of time to conclude, which could create a drain on our resources. Furthermore, we operate in industries that have stringent performance requirements. As a result, incorrect or incomplete assessments of the performance of customers in those industries could give rise to negligence or other legal claims or cause damage to our reputation and, as a result, we could lose existing or future agreements with those customers. Even if our TIC services are carried out competently, we may face claims simply because we tested the product, facility, process, component or system in question.

The current liability regime in the United States and other markets generally minimizes our exposure to product liability claims, in large part because we typically test prototypes. We have also historically been able to contractually limit our liability or protect ourselves from liability through the use of indemnification provisions in our agreements with customers. If we were to start testing end products instead of their prototypes, if the law regarding products liability were to change unfavorably or if we were unable to contractually limit the scope of our potential liability, our business could be materially adversely affected.

Although we attempt to contractually limit our liability and make clear the limited scope of our engagements, there can be no assurance that we will be able to protect ourselves against claims or damage to our reputation resulting from an accident, disaster or other incident or litigation giving rise to substantial media coverage, particularly if any such publicity suggests substantial failures, real or alleged, by us in discharging our responsibilities. Serious damage to our reputation could result in us losing existing and future agreements or make it more difficult for us to compete effectively, any of which would have a

26

negative impact on our financial performance. Any of the foregoing events could significantly damage our reputation or otherwise have a material adverse effect on our business, financial condition and results of operations.

Our reports, certificates, certification marks and name are at risk of being falsified, counterfeited, forged, tampered with or otherwise misused, which could result in costly legal proceedings and damage to our brand and reputation and materially impact our business.

Our core business involves the assessment of products, facilities, processes, components and systems against various legal, regulatory and industry requirements—typically standards and regulations governing quality, safety, performance, sustainability and social responsibility. We act as an independent body and issue reports, certificates and a right to use certification marks generally representing that products, facilities, processes, components and systems conform to applicable requirements.

Because obtaining certification is often vital for our customers and can enhance the marketability of their products, we are exposed to the risk that our reports or certifications could be falsified or tampered with, or that counterfeit reports, certifications or certification marks could be used, infringing our trademarks or copyrights. For example, a customer or other third party could falsely claim that their products or services have been certified by us or misrepresent or misconvey the content or nature of our reports, certifications or other assessments. The production of forged or counterfeit reports, certificates or certification marks can result from employee conduct or, more commonly, external sources, such as fraudulent behavior by a customer or third party aiming to meet regulatory requirements or the requirements of their customers or to gain market access. For example, we endeavor to contractually restrict customers from using our reports, certificates, certification marks and name, but we are not always successful, including as a result of breaches of contract by those customers. Such unauthorized or unrestricted use of our reports, certificates, certification marks and name may cause damage to our reputation or result in unintended third parties relying on such reports, certificates, certification marks and name, among other consequences.

The fraudulent creation or use of our reports, certifications, certification marks or name could lead to the introduction of dangerous products into the marketplace; result in civil and criminal legal proceedings against us or brought by us; threaten our ability to maintain or renew the accreditations, approvals, permits, delegations of authority, official recognition and other authorizations we need to pursue certain activities that are important to our business; result in the withdrawal of certain products from the market or damage our reputation and the TIC industry in general. It could also adversely and significantly impact our reputation, brand, business, financial condition and results of operations.

Our earnings and profitability may vary based on the mix of our agreements and may be adversely affected by our failure to accurately estimate and manage costs, time and resources.

We generate revenue under various types of agreements, which include time-and-materials and fixed-price agreements. We use time-and-materials agreements for certain of our advisory services. While charges under a fixed-price agreement are based on a fixed price, charges under a time-and-materials agreement are calculated by multiplying an agreed hourly rate by the number of hours incurred, and customers are typically invoiced on a monthly basis. For time-and-materials agreements, there is usually an estimated number of hours or a budget, and the term of the agreement is typically as long as it takes to complete a particular project or set of tasks, although it can also be open-ended if the agreement is a straight hourly agreement. In some cases, we may also charge customers on what we refer to as a cost-plus basis—using a reasonable mark-up, as determined by us, on expenses we incur in providing our services.

Our earnings and profitability may vary materially depending on changes in the proportionate amount of revenues derived from each type of agreement, the percentage of completion, the nature of services or solutions provided, as well as the achievement of performance objectives and the stage of performance at which the right to receive fees, particularly under incentive fee agreements, is finally determined. To varying degrees, each of our agreement types involves some risk that we could underestimate the costs and resources necessary to fulfill the agreement. Our profitability is adversely affected when we incur costs on cost-plus and time-and-materials agreements that we cannot bill to our customers. While fixed-price agreements allow us to benefit from cost savings, these agreements also increase our exposure to the risk of cost overruns.

Revenue derived from fixed-price agreements represented the majority of our total revenue for the year ended December 31, 2024. When making proposals on fixed-price agreements, we rely heavily on our estimates of costs, scope and timing for completing the associated projects, as well as assumptions regarding technical issues. In each case, our failure to accurately estimate costs, scope or the resources and technology needed to perform our agreements or to effectively manage and control our costs during the performance of work could result, and in some instances has resulted, in reduced profits or in losses. More generally, any increased or unexpected costs or unanticipated delays in connection with the performance of our

27

agreements, including costs and delays caused by contractual disputes or other factors outside of our control, such as performance failures of our subcontractors, natural disasters or other force majeure events, could make our agreements less profitable than expected or unprofitable.

Our focus on new growth areas for our business entails risks, including those associated with new relationships, customers, talent needs, capabilities and services.

We are focused on growing our presence in our addressable markets by offering TIC services and S&A solutions to both established and emerging industry verticals to which we do not offer services currently, extending into opportunity-rich adjacent markets and acquiring and integrating transformative, disruptive technologies. These efforts entail inherent risks associated with innovation, potential failure to help our customers respond to the challenges they face, shortages of necessary talent and our ability to comply with uncertain evolving legal standards. Some of our targeted growth areas in established and emerging industry verticals and adjacent markets subject us to new risks that we may not be equipped to address. As we attempt to develop new capabilities and service offerings in new markets, and to attract new customers, these efforts could harm our results of operations due to, among other things, a diversion of our focus and resources and actual costs, opportunity costs of pursuing these opportunities in lieu of others and a failure to reach a profitable return on our investments in new technologies, capabilities and businesses, including expenses on research and development investments. If we fail to develop new capabilities, our ability to procure new agreements could be negatively impacted, which would negatively impact our business, results of operations and financial condition.

Although we closely monitor the quality of our services, attempt to contractually limit our liability and make clear the limited scope of our engagements, carefully review technical and operational decisions and maximize communication between our engineers and global leadership, there can be no assurance that we will be able to protect ourselves against claims or damage to our reputation resulting from an accident, disaster or other incident or litigation giving rise to substantial media coverage, particularly if any such publicity suggests substantial failures, real or alleged, by us in discharging our responsibilities. Serious damage to our reputation could result in us losing existing and future agreements or make it more difficult for us to compete effectively, any of which would have a negative impact on our financial performance. Any of the foregoing events could significantly damage our reputation or otherwise have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Conducting Business in China

Changes in U.S. and Chinese regulations could have a material adverse effect on our business, financial condition, results of operations, our ability to raise capital and the market price of our Class A common stock.

The U.S. government has taken certain actions that impact companies with connections to the United States or China, including imposing several rounds of tariffs affecting certain products manufactured in China and imposing certain sanctions and restrictions in relation to certain Chinese companies, entities and individuals. It is unknown whether and to what extent new legislation, executive orders, tariffs, laws or regulations will be adopted, such as those set forth in the notice of proposed rulemaking concerning Promoting the Integrity and Security of Telecommunication Certification Bodies, Measurement Facilities and the Equipment Authorization Program recently issued by the United States Federal Communications Commission, or the effect that any such actions would have on companies with significant connections to the United States or to China, our industry or on us, including on UL-CCIC. We have business operations both in the United States and China. Any unfavorable government policies on cross-border investments or other transactions or international trade, including increased scrutiny on U.S. companies with significant China-based operations, capital controls or tariffs, may affect our competitive position, our ability to raise capital, the hiring of personnel or the demand for our services or prevent us from offering our services in China or contracting with Chinese customers.

Further, ongoing tensions between the United States and China continue to pose a risk of the United States imposing economic or trade sanctions, expanding the scope of companies, entities and individuals which are subject to such sanctions, or heightening export controls, with respect to parties in China, which could restrict our ability to do business in China or with parties in China. For instance, the Bureau of Industry and Security of the U.S. Department of Commerce has added a number of Chinese parties to its Entity List and the Office of Foreign Asset Control of the U.S. Department of the Treasury has designated a number of Chinese parties to its Specially Designated Nationals list. Such restrictions would prevent us, including UL-CCIC, where applicable, from selling certain products or providing certain services to entities on the list without a license issued subject to the Export Administration Regulations, or from conducting any business with those entities. Further, if additional parties in China, including current customers and suppliers of our business, are added to the Entity List, or to other lists of restricted or prohibited persons maintained by the United States government, that could negatively affect our business, including the business of UL-CCIC.

28

Additionally, in 2021 China enacted the Law on Countering Foreign Sanctions, under which foreign persons (individuals and companies) can be subjected to countermeasures for directly or indirectly participating in a foreign country’s “discriminatory restrictive measures” against Chinese entities, which could include adherence to U.S. or other foreign sanctions or, in some circumstances, export or other trade controls. Countermeasures authorized under the law include the seizure of property, barring transactions with individuals within the territory of China or entities incorporated under Chinese laws, denial of visas or deportation. This law expands on and supplements the Ministry of Commerce’s September 2020 Provisions of the Unreliable Entity List and January 2021 Rules on Counteracting Unjustified Extra-territorial Application of Foreign Legislation, which created a private right of action under which Chinese entities can sue for damages they allege resulted from a company adhering to “discriminatory foreign measures.”

If any new legislation, executive orders, tariffs, sanctions, export controls, laws or regulations are implemented, if existing trade agreements are renegotiated or if the U.S. or Chinese governments take further retaliatory actions in response to the recent bilateral tensions, such changes could have a material adverse effect on our business, financial condition and results of operations, and the market price of our Class A common stock.

Our business is subject to the complex and rapidly evolving laws and regulations in China. The Chinese government may exercise significant oversight and discretion over the conduct of our, including UL-CCIC’s, business there and may intervene in or influence our operations, which could result in a material adverse change in our, including UL-CCIC’s, operations or the value of our Class A common stock.

As a U.S.-headquartered global company that conducts significant business in China, our Chinese operations are subject to China’s laws and regulations, which can be complex and evolve rapidly. The regulations to which we are subject in China may change rapidly and with little or no notice to us. As a result, the application, interpretation and enforcement of new and existing laws and regulations in China are often uncertain. These laws and regulations may also be interpreted and applied or enforced inconsistently by different agencies or authorities, or inconsistently with our current policies and practices. New and evolving laws, regulations and other government directives in China may also be costly to comply with. Such compliance, any associated inquiries or investigations or any other government actions or the inconsistent interpretation, application or enforcement of laws or regulations could impact our China operations in the following ways:

•delay or impede our development;

•result in negative publicity, decrease demand for our services or increase our operating costs;

•require significant management time and attention;

•require us to obtain additional licenses, permits, approvals or certificates;

•require us to exit certain industries or stop conducting business with certain customers; or

•subject us to remedies, administrative penalties and even criminal liabilities that may harm our business, including fines assessed for our current or historical operations, or demands or orders that we refrain from contracting with customers in China or modify or even cease our business practices in China.

The interpretation and enforcement of laws and regulations in China involve additional uncertainties. Because Chinese administrative and court authorities have significant discretion in interpreting and implementing statutory provisions and contractual terms, it may be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we may obtain. These uncertainties may affect our judgment on the relevance of legal requirements in China and our ability to enforce our contractual rights or tort claims there. In addition, third parties might exploit regulatory uncertainties through unmerited or frivolous legal actions or threats to extract payments or benefits from us.

Furthermore, the Chinese legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have a retroactive effect. As such, we may not be aware of our violation of any of these policies and rules until after such violation occurs. In addition, administrative and court proceedings in China in which we may become involved in the future may be protracted, resulting in substantial costs and diversion of resources and require significant management time.

Regulatory developments in China may also lead to additional regulatory review in China over our activities there. For example, in recent years, the Chinese government has published new policies that significantly affect certain industries, such as the education and internet industries, and we cannot rule out the possibility that the Chinese government will release new

29

or revised regulations or policies concerning or impacting our industry. Any such new or revised regulations or policies could limit our service offerings, restrict the scope of our operations in China, require us to seek permission from Chinese authorities to continue to operate our businesses or cause the suspension or termination of our business in China entirely, all of which would materially adversely affect our business, financial condition, results of operations and value of our Class A common stock. We may have to adjust, modify or completely change our business operations in response to adverse regulatory changes or policy developments, and we cannot guarantee that any remedial action adopted by us can be completed in a timely, cost-efficient or liability-free manner, or at all.

Furthermore, the Chinese government has exercised and continues to exercise substantial control over virtually every sector of the Chinese economy through regulation and state ownership and has the power to exercise significant oversight and discretion over the conduct of our business in China. This risk is heightened with respect to UL-CCIC because UL-CCIC is minority owned by CCIC, a Chinese state-owned entity, and UL-CCIC’s ability to operate in China may be materially and adversely affected by the Chinese government’s significant oversight and discretion over the conduct of UL-CCIC’s business. Government actions in the future could significantly affect economic conditions in China and could require us, including UL-CCIC, to materially change our operating activities or require us to divest ourselves of any interests we hold in Chinese assets. Our business may be subject to government and regulatory interference in the provinces in which we operate, and we may incur increased costs necessary to comply with existing and newly adopted laws and regulations or penalties for any failure to comply.

If our relationship with CCIC were to be negatively impacted, if we are unable to renew our joint venture with CCIC in the future, or if the joint venture were to be terminated, our business, financial condition, results of operations and profitability would be materially adversely affected.

On October 28, 2022, we entered into an amended and restated joint venture agreement with CCIC pursuant to which we own a direct 70% equity interest in UL-CCIC. The amended and restated agreement expires in January 2033. If, in the future, we are unable to renew the agreement on existing or more favorable terms, or at all, or if the joint venture were to be terminated, our business, reputation, financial condition, results of operations and profitability would likely be materially adversely impacted, and we may be unable to find an alternative partner for our China-based inspections business. We also have a separate contract with CCIC pursuant to which CCIC’s staff conduct inspections for our TIC business in China, including as a subcontractor for UL-CCIC. In 2024, CCIC was responsible for approximately 36% of our global inspections. If we were to lose our contract with CCIC, or if CCIC were to stop providing inspection services for us in the future, our business would be impacted significantly, and any negative impacts on our relationship with CCIC, including our joint venture, would have a material adverse effect on our business, financial condition, results of operations and profitability. As a minority joint-venture partner, CCIC has certain protective rights, whether contractually or pursuant to applicable local laws and regulations, and may have economic or business interests or goals that are not consistent with ours, or may, as a result of financial or other difficulties, be unable or unwilling to fulfill their obligations as a minority joint-venture partner.

Furthermore, we may be exposed to certain commercial and reputational risks as a result of CCIC being a state-owned entity and thus controlled by the Chinese government. For example, CCIC may make politically motivated business decisions that do not align with our commercial interests. In addition, CCIC could conduct business with other companies, organizations or institutions that attract unfavorable political attention in the United States, which could harm our reputation. Any such actions could negatively impact our relationship with CCIC, which would materially and adversely affect our business, financial condition, results of operations and profitability.

If the government of China determines that UL-CCIC’s ownership structure, or the ownership structure of our other Chinese subsidiaries, does not comply with any current or future regulatory restrictions, or if these regulations or the interpretation of existing regulations change in the future, we, including UL-CCIC, could be subject to severe penalties, or we could be forced to relinquish our interests in UL-CCIC’s or our other Chinese subsidiaries’ operations.

The industry sector in which we operate in China is currently not subject to foreign ownership restrictions, and hence we, through our wholly owned subsidiary, UL LLC, are able to hold a direct equity interest in UL-CCIC. However, it is possible that Chinese foreign ownership rules applicable to our sector may change in the future, which could adversely impact our ownership of UL-CCIC or of our other Chinese subsidiaries, and, as a result, have a material adverse effect on our business in China. For example, we may have to reduce our interest in UL-CCIC if tighter ownership limits are imposed, or divest our stake in UL-CCIC altogether should the sector become prohibited from foreign investment.

Our joint venture agreement with CCIC has not been tested in a court of law. However, if disputes with CCIC arise, or the ownership structure, joint venture terms or business of UL-CCIC are challenged and found to be unenforceable or in violation of any existing or future Chinese laws or regulations, we may not be able to enforce our rights under the joint venture

30

agreement. Furthermore, if the interpretation of any such Chinese laws or regulations changes, our rights under the joint venture agreement may be similarly unenforceable. If a violation of relevant laws or regulations is found, the relevant regulatory authorities would have broad discretion to take action in dealing with such violations by, among other things:

•revoking our, including UL-CCIC’s, business or operating licenses;

•shutting down our, including UL-CCIC’s, servers, blocking our, including UL-CCIC’s, website or discontinuing or placing restrictions or onerous conditions on our operation through any transactions involving UL-CCIC or any of our other Chinese subsidiaries;

•imposing fines, confiscating the income of UL-CCIC or any of our other Chinese subsidiaries, blocking the offshore remittance of the profits and earnings of UL-CCIC or of any of our other Chinese subsidiaries or imposing other requirements with which we, including UL-CCIC, may not be able to comply;
