Significant Accounting Policies Description of Business UL Solutions Inc. (together with its consolidated subsidiaries, “UL Solutions” and the “Company,” unless the context otherwiserequires) is a global safety science leader that provides independent third-party testing, inspection and certification services, advisoryofferings and software solutions. Underwriters Laboratories Inc. (“UL Research Institutes”) is the sole member of ULSE Inc. (“ULStandards & Engagement”), which controls the majority of the voting power of the Company’s common stock. Effective beginning in the first quarter of 2026, the Company reorganized its segments to be consistent with how the Chief ExecutiveOfficer currently evaluates business performance and allocates resources. The changes primarily related to the Company’s Advisorybusiness, which was previously included within the Software and Advisory segment and is now included within the Industrialsegment. As a result of the reorganization, the Software and Advisory segment was renamed “Risk & Compliance Software” and costsrelated to the Company’s corporate functions were reallocated across its segments. The prior period amounts within Note 8,“Goodwill”and Note 19,“Segment Information”,have been recast to reflect the Company’s segment reorganization. Thisreorganization had no impact on the Company’s consolidated financial position, results of operations or cash flows.
