Subsequent Events	Subsequent Events Restructuring Initiative On November 4, 2025, the Company announced an expense reduction initiative to further improve the operating model and exit certain lines of business that are no longer considered strategically important to the Company (the “Restructuring Plan”). The Company expects to incur pre-tax expenses associated with the Restructuring Plan of approximately $42-$47 million in the aggregate, consisting of $37-$42 million in cash charges relating to employee separation expenses and approximately $5 million in other cash charges, primarily relating to contract cancellations. The majority of costs associated with the Restructuring Plan are expected to be recorded in the fourth quarter of 2025 in the Consumer and Industrial segments. The Company anticipates the Restructuring Plan will be substantially completed by the end of the first quarter of 2027. 2025 Credit Facility On October 28, 2025, UL Solutions Inc. entered into a Credit Agreement (the “Credit Agreement”), by and among the Company and certain of its non-U.S. subsidiaries as co-borrowers (collectively, the “Borrowers”), Bank of America, N.A., as administrative agent, and the lenders party thereto. The Credit Agreement provides for a $1.0 billion senior unsecured five-year multi-currency revolving facility (the “2025 Credit Facility”), with a $25 million sub-limit for the issuance of letters of credit. The Credit Agreement includes an accordion feature permitting an increase in the 2025 Credit Facility by an aggregate amount of up to $500 million, subject to the consent of any lenders providing such increase, the absence of any default or event of default and entry into customary documentation with respect to such increase. The Borrowers’ obligations (other than the Company’s) under the Credit Agreement are guaranteed by the Company. On October 28, 2025, the Company borrowed $291 million under the 2025 Credit Facility. The initial borrowing was used to refinance the outstanding amounts under the 2022 Credit Facility. Additional amounts, if any, borrowed under the 2025 Credit Facility are anticipated to be used for general corporate purposes. Borrowings under the 2025 Credit Facility bear interest at a rate per annum equal to, at the applicable Borrower’s option, (a) a specified benchmark rate for the applicable currency (which, in the case of U.S. Dollar loans, shall be the Term SOFR or Daily SOFR (in each case as defined in the Credit Agreement), at the applicable Borrower’s option), plus a margin that ranges from 0.875% to 1.375% per annum or (b) for U.S. Dollar loans made to the Company only, a base rate (which is equal to the highest of (i) the Bank of America prime rate, (ii) the U.S. federal funds rate plus 0.5% per annum, or (iii) the Term SOFR or Daily SOFR rate plus 1.0%) plus a margin that ranges from 0.0% to 0.375% per annum. The 2025 Credit Facility matures on October 28, 2030 and may be prepaid without fees or penalties, subject to reimbursement of the lenders’ customary breakage and redeployment costs in applicable cases. The 2025 Credit Facility also includes a financial covenant, tested quarterly, which requires the Company to maintain a consolidated net leverage ratio of not greater than 3.5 to 1.0, calculated on a consolidated basis for each consecutive four fiscal quarter period, with an increase in the maintenance level to 4.0 to 1.0 for each of the four test periods immediately following any permitted acquisition that involves the payment of aggregate consideration in excess of $100 million, subject to a two fiscal quarter rest period between increases for separate acquisitions. The calculation of the consolidated net leverage ratio permits the netting of up to $250 million of unrestricted cash from funded debt. The 2025 Credit Facility includes customary representations and warranties, covenants and events of default, subject to certain customary exceptions, materiality thresholds and grace periods. The covenants include, among other things, financial reporting, maintenance of line of business, notices of default and other material changes, as well as limitations on investments and acquisitions, mergers and transfers of all or substantially all assets, dividends and distributions, burdensome contracts with affiliates, liens and indebtedness. Future borrowings under the 2025 Credit Facility are subject to the satisfaction of customary conditions, including the absence of any default or event of default and the accuracy of representations and warranties. On October 28, 2025, in connection with the entry into the Credit Agreement described above, the Company repaid in full all indebtedness and other obligations outstanding under, and terminated, the 2022 Credit Facility.
