•Organic net sales were down 6% primarily driven by lower volumes in our Health & Science Technologies segment.
•Gross margin of 44.6% decreased 60 bps and Net income margin of 15.2% decreased 130 bps primarily due to lower volume leverage and higher employee-related costs, partially offset by strong price/cost and favorable operational productivity. Additionally, these margins were unfavorably impacted by restructuring and fair value inventory step-up charges, while lower interest expense and lower income taxes benefited Net income margin.
•Adjusted gross margin of 45% decreased 20 bps and Adjusted EBITDA margin of 26% decreased 120 bps excluding the impacts of restructuring and fair value inventory step-up charges.
•Reported and Adjusted diluted EPS benefited from lower interest expense and a discrete tax benefit recognized during the current year period, which partly mitigated the impacts discussed above.

Fluid & Metering Technologies Segment
•Organic net sales for the first quarter 2024 were negatively impacted by lower volumes, primarily in the industrial markets, largely driven by non-repeat of projects from the prior year and greater reduction of backlog in the prior year. This decrease was partially offset by price capture across all markets.
•Organic Adjusted EBITDA margin for the first quarter 2024 increased primarily due to favorable operational productivity and strong price/cost, partially offset by lower volume leverage, unfavorable mix, higher employee-related costs and higher discretionary spending.
Health & Science Technologies Segment
•Organic net sales for the first quarter 2024 were negatively impacted by lower volumes, primarily in the analytical instrumentation, life sciences and semiconductor markets, largely driven by inventory recalibration and the carryover of market slowness from 2023. This decrease was partially offset by price capture across all markets.
•Organic Adjusted EBITDA margin for the first quarter 2024 decreased primarily due to lower volume leverage, higher employee-related costs and unfavorable mix, partially offset by favorable operational productivity, lower discretionary spending, and strong price/cost.
Fire & Safety/Diversified Products Segment
•Organic net sales for the first quarter 2024 were positively impacted by price capture across all markets. Volumes were flat period over period.
•Organic Adjusted EBITDA margin for the first quarter 2024 increased primarily due to strong price/cost and lower discretionary spending, partially offset by higher employee-related costs.

Non-GAAP Measures of Financial Performance
The Company prepares its public financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP). The Company supplements certain GAAP financial performance metrics with non-GAAP financial performance metrics. Management believes these non-GAAP financial performance metrics provide investors with greater insight, transparency and a more comprehensive understanding of the financial information used by management in its financial and operational decision making because certain of these adjusted metrics exclude items not reflective of ongoing operations, as identified in the reconciliations below. Reconciliations of non-GAAP financial performance metrics to their most directly comparable GAAP financial performance metrics are defined and presented below and should not be considered a substitute for, nor superior to, the financial data prepared in accordance with GAAP. Due to rounding, numbers presented throughout this and other documents may not add up or recalculate precisely. There were no adjustments to GAAP financial performance metrics other than the items noted below.
•Organic orders and net sales are calculated excluding amounts from acquired or divested businesses during the first twelve months of ownership or prior to divestiture and the impact of foreign currency translation.
•Adjusted gross profit is calculated as gross profit plus fair value inventory step-up charges.
•Adjusted gross margin is calculated as adjusted gross profit divided by net sales.
•Adjusted net income attributable to IDEX is calculated as net income attributable to IDEX plus fair value inventory step-up charges, plus restructuring expenses and asset impairments, plus acquisition-related intangible asset amortization, all net of the statutory tax expense or benefit.
•Adjusted diluted EPS attributable to IDEX is calculated as adjusted net income attributable to IDEX divided by the diluted weighted average shares outstanding.
•Consolidated Adjusted EBITDA is calculated as consolidated earnings before interest expense - net, taxes, depreciation and amortization, or consolidated EBITDA, plus fair value inventory step-up charges plus restructuring expenses and asset impairments.
•Consolidated Adjusted EBITDA margin is calculated as Consolidated Adjusted EBITDA divided by net sales.
•Free cash flow is calculated as cash flow from operating activities less capital expenditures.
