Note 5Fair Value Measurements Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. These requirements establish market or observable inputs as the preferred source of values. Assumptions based on hypothetical transactions are used in the absence of market inputs. The Company does not have any non-financial instruments accounted for at fair value on a recurring basis. The valuation techniques required are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Companys market assumptions. These two types of inputs create the following fair value hierarchy: Level 1 Quoted prices for identical instruments in active markets. Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Significant inputs to the valuation model are unobservable. The Company believes that the assets and liabilities currently subject to such standards with fair value disclosure requirements are primarily (i) debt instruments, (ii) pension plan assets, and (iii) assets acquired and liabilities a …

Note 10Benefit Plans and Other Postretirement Benefits The Company and certain of its domestic subsidiaries have defined benefit pension plans (the U.S. Pension Plans), which cover certain U.S. employees and which represent the majority of the plan assets and benefit obligations of the aggregate defined benefit plans of the Company. The U.S. Pension Plans benefits are generally based on years of service and compensation and are generally noncontributory. The majority of U.S. employees are not covered by the U.S. Pension Plans and are instead covered by various defined contribution plans. The Company also has an unfunded Supplemental Employee Retirement Plan (SERP and, together with the U.S. Pension Plans, U.S. Plans), which provides for the payment of the portion of annual pension that cannot be paid from the retirement plan as a result of regulatory limitations on average compensation for purposes of the benefit computation. Certain foreign subsidiaries have defined benefit plans covering their employees (the Foreign Plans and, together with the U.S. Plans, the Plans). The following is a summary, based on the most recent actuarial valuations, of the components of the Companys net pension expense of the Companys defined benefit plans for the three and six months ended June 30, 2026 and 2025: Three Months Ended Six Months Ended June 30, June 30, 2026 2025 2026 2025 Service cost $ 1.4 $ 0.7 $ 2.8 $ 1.5 Interest cost 7.6 5.9 15.2 11.7 Expected return on plan assets (8.4) (6.6) ( …

Note 14Revenue Recognition Revenues consist of product sales to either end customers and their appointed contract manufacturers (including original equipment manufacturers) or to distributors, and the vast majority of our sales are recognized at a point-in-time under the core principle of recognizing revenue when control transfers to the customer. With limited exceptions, the Company recognizes revenue at the point in time when we ship or deliver the product from our manufacturing facility to our customer, when our customer accepts and has legal title of the goods, and where the Company has a present right to payment for such goods. For the three and six months ended June 30, 2026 and 2025, less than 5% of our net sales were recognized over time, where the associated contracts relate to the sale of goods with no alternative use as they are only sold to a single customer and whose underlying contract terms provide the Company with an enforceable right to payment, including a reasonable profit margin, for performance completed to date, in the event of customer termination. Since we typically invoice our customers at the same time that we satisfy our performance obligations, contract assets and contract liabilities related to our contracts with customers recorded in the Condensed Consolidated Balance Sheets were not material as of June 30, 2026 and December 31, 2025. These amounts are recorded in the accompanying Condensed Consolidated Balance Sheets within Prepaid expenses and …
