Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures, defines fair value, provides guidance for measuring fair value and requires certain disclosures. This standard discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs, other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the reporting entitys own assumptions. The following table summarizes the basis used to measure the Companys financial assets (liabilities) at fair value on a recurring basis in the balance sheets at December 31, 2025 and 2024: December 31, 2025 Level 1 Level 2 Level 3 Total Assets Trading securities - mutual funds held in nonqualified SERP (1) $ 10.8 $ $ $ 10.8 Liabilities Contingent consideration …

In assessing the fair value of the reporting units, the Company considers both the market approach and the income approach.

Restructuring Expenses and Asset Impairments Restructuring expenses generally represent expenses incurred by the Company to facilitate long-term sustainable growth through cost reduction actions, consisting of employee reductions, facility rationalization and contract termination costs. These costs include severance costs, exit costs and asset impairments and are included in Restructuring expenses and asset impairments in the Consolidated Statements of Income. Severance costs primarily consist of severance benefits through payroll continuation, COBRA subsidies, outplacement services, conditional separation costs, employer tax liabilities and related legal costs, while exit costs primarily consist of lease exit and contract termination costs. 2025 Initiative In January 2025, the Company initiated restructuring actions designed with the focus of connecting scalable groups of businesses, which resulted in a reduction of headcount. Additionally, the Company eliminated certain management layers in select areas. These changes are expected to enable the Company to self-fund more growth resources, increase sourcing productivity, improve agility and speed of decision making and position the Company closer to the customer for maximum impact. These actions, which have primarily resulted in recognizing severance costs related to employee reductions, have been substantially completed during 2025.

Business Segments and Geographic Information IDEX has three operating business segments, which are the same as our reportable business segments: HST, FMT and FSDP. The Company has determined its segments based on how financial information is reviewed by the chief operating decision maker (CODM) to analyze financial performance, make decisions and allocate resources. The Companys CODM is the Chief Executive Officer. The Companys CODM evaluates the performance of the segments and allocates resources to them based on Adjusted EBITDA. Segment Adjusted EBITDA includes intersegment revenues as well as charges allocating certain corporate overhead costs. Intersegment sales are contracted with terms equivalent to those of an arms-length transaction. Adjusted EBITDA is the Companys measure of segment performance. For all segments, the CODM uses Adjusted EBITDA in the annual budgeting and forecasting process.
