NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in millions, except per share amounts)

(unaudited)

1.    Basis of Presentation and Significant Accounting Policies

The Condensed Consolidated Financial Statements of IDEX Corporation (“IDEX” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) applicable to interim financial information and the instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended. The statements are unaudited but include all adjustments, consisting only of recurring items, except as noted, that the Company considers necessary for a fair presentation of the information set forth herein. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the entire year.

The Condensed Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations set forth in this report should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Recently Issued Accounting Standards

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves the disclosures required for reportable segments in the Company’s annual and interim financial statements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Adoption of this ASU should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard on the Consolidated Financial Statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to disclose standard categories in tax rate reconciliations, additional information for reconciling items that meet a quantitative threshold and income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard on the Consolidated Financial Statements and disclosures.

2.    Acquisitions

All of the Company’s acquisitions of businesses have been accounted for under Accounting Standards Codification (“ASC”) 805, Business Combinations. Accordingly, the assets and liabilities of the acquired companies, after adjustments to reflect the fair values assigned to the assets and liabilities, have been included in the Condensed Consolidated Balance Sheets from their respective dates of acquisition. The results of operations of businesses acquired have been included in the Condensed Consolidated Statements of Income since their respective dates of acquisition. Supplemental pro forma information has not been provided as the acquisitions did not have a material impact on the Condensed Consolidated Financial Statements individually or in the aggregate.

The Company makes a preliminary allocation of the purchase price for each acquisition as of the acquisition date based on its understanding of the fair value of the acquired assets and assumed liabilities. These nonrecurring fair value measurements are classified as Level 3 in the fair value hierarchy. As the Company continues to obtain additional information, primarily related to the valuations of these assets and liabilities, and continues to integrate the newly acquired business, the Company will refine the estimates of fair value and more accurately allocate the purchase price through the completion of the measurement period, which is not to exceed one year from the date of acquisition. Only items identified as of the acquisition date are considered for subsequent adjustment.

Performance Obligations

The Company’s performance obligations are satisfied either at a point in time or over time as work progresses. Revenue from products and services transferred to customers at a point in time comprised approximately 95% of the Company’s revenue and over time comprised approximately 5% of the Company’s revenue for both the three months ended March 31, 2024 and 2023, respectively.

Contract Assets and Liabilities

The timing of billings and cash collections can result in customer receivables, billings in excess of revenue recognized, advance payments or deposits. Customer receivables include both amounts billed and currently due from customers as well as unbilled amounts (contract assets) and are included in Receivables - net on the Condensed Consolidated Balance Sheets.

The composition of customer receivables was as follows:

	March 31, 2024		December 31, 2023
Billed receivables	$	419.4	$	408.1
Unbilled receivables	9.7		10.9
Total customer receivables	$	429.1	$	419.0

Billings in excess of revenue recognized, advance payments and deposits represent contract liabilities and are included in deferred revenue which is classified as current or noncurrent based on when the Company expects to recognize the revenue. The current portion is included in Accrued expenses and the noncurrent portion is included in Other noncurrent liabilities on the Condensed Consolidated Balance Sheets.

Deferred revenue - noncurrent	17.9		17.3
Total deferred revenue	$	80.3	$	73.2

5.    Earnings Per Common Share

Diluted earnings per common share (“EPS”) attributable to IDEX is computed by dividing Net income attributable to IDEX by the weighted average number of common shares outstanding (basic) plus common stock equivalents outstanding (diluted) for the period. Common stock equivalents consist of restricted stock, performance share units and stock options, which have been included in the calculation of weighted average common shares outstanding using the treasury stock method.

ASC 260, Earnings Per Share (“ASC 260”), concludes that all outstanding unvested share-based payment awards that contain rights to non-forfeitable dividends participate in undistributed earnings with common shareholders. If awards are considered participating securities, the Company is required to apply the two-class method of computing basic and diluted earnings per share. The Company has determined that its outstanding shares of restricted stock are participating securities. Accordingly, Diluted EPS attributable to IDEX was computed using the two-class method prescribed by ASC 260.

Basic weighted average common shares outstanding reconciles to diluted weighted average common shares outstanding as follows:

	Three Months Ended March 31,
	2024	2023
Basic weighted average common shares outstanding	75.7	75.6
Dilutive effect of restricted stock, performance share units and stock options	0.2	0.3
Diluted weighted average common shares outstanding	75.9	75.9

Share-based payment awards of approximately 0.5 million and 0.2 million shares of common stock for the three months ended March 31, 2024 and 2023, respectively, were not included in the computation of Diluted EPS attributable to IDEX because the effect of their inclusion would have been antidilutive.

ASC 350, Goodwill and Other Intangible Assets (“ASC 350”), requires that goodwill be tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. Annually, on October 31, goodwill and other acquired intangible assets with indefinite lives are tested for impairment. Based on the results of the Company’s annual impairment test at October 31, 2023, all reporting units had fair values in excess of their carrying values. During the three months ended March 31, 2024, there were no events or circumstances that would have required an interim impairment test.

The Banjo and Akron Brass trade names are indefinite-lived intangible assets which are tested for impairment on an annual basis in accordance with ASC 350 or more frequently if events or changes in circumstances indicate that the assets might be impaired. Based on the results of the Company’s annual impairment test at October 31, 2023, these indefinite-lived intangible assets had fair values in excess of their carrying values. During the three months ended March 31, 2024, there were no events or circumstances that would have required an interim impairment test on these indefinite-lived intangible assets.

Amortization of intangible assets was $24.6 million and $23.6 million for the three months ended March 31, 2024 and 2023, respectively. Based on the intangible asset balances as of March 31, 2024, expected amortization expense for the remaining nine months of 2024 and for the years 2025 through 2028 is as follows:

9.    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 entity’s own assumptions.

The following table summarizes the basis used to measure the Company’s financial assets (liabilities) at fair value on a recurring basis in the balance sheets at March 31, 2024 and December 31, 2023:

	Basis of Fair Value Measurements
	March 31, 2024		December 31, 2023
	Level 1		Level 1
Trading securities - mutual funds held in nonqualified SERP(1)	$	10.3	$	10.5
Available-for-sale securities - equities(2)	4.4		4.4

(1) The Supplemental Executive Retirement Plan (“SERP”) investment assets are offset by a SERP liability which represents the Company’s obligation to distribute SERP funds to participants. The SERP investment assets and liability are included in Other noncurrent assets and Other noncurrent liabilities, respectively, on the Condensed Consolidated Balance Sheets.

(2) The securities are included in Other current assets on the Condensed Consolidated Balance Sheets and are available for overnight cash settlement, if necessary, to fund current operations.

There were no transfers of assets or liabilities between Level 1 and Level 2 during the three months ended March 31, 2024 or the year ended December 31, 2023.

The carrying values of the Company’s cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value because of the short-term nature of these instruments.

The following table provides the fair value of the outstanding indebtedness described in Note 8, “Borrowings,” which is based on quoted market prices and current market rates for debt with similar credit risk and maturity, as well as the carrying value. These fair value measurements are classified as Level 2 within the fair value hierarchy since they are determined based upon significant inputs observable in the market, including interest rates on recent financing transactions to entities with a credit rating similar to the Company’s rating.

	March 31, 2024				December 31, 2023
	Fair Value		Carrying Amount		Fair Value		Carrying Amount
Total Borrowings, less unaccreted debt discount	$	1,239.7	$	1,329.9	$	1,203.5	$	1,332.2

11.    Share Repurchases

On March 17, 2020, the Company’s Board of Directors approved an increase of $500.0 million in the authorized level of repurchases of common stock. This approval is in addition to the prior repurchase authorization of the Board of Directors of $300.0 million on December 1, 2015. These authorizations have no expiration date. There were no share repurchases during the three months ended March 31, 2024 and 2023. As of March 31, 2024, the amount of share repurchase authorization remaining was $539.7 million.

12.   Share-Based Compensation

The Company typically grants equity awards annually at its regularly scheduled first quarter meeting of the Board of Directors based on the recommendation from the Compensation Committee.

The Company’s policy is to recognize compensation cost on a straight-line basis, assuming forfeitures, over the requisite service period for the entire award. Classification of share-based compensation cost within the Condensed Consolidated Statements of Income is consistent with the classification of cash compensation for the same employees.

Stock Options

Stock options granted under the Company’s plans are generally non-qualified and are granted with an exercise price equal to the market price of the Company’s stock on the date of grant. The fair value of each option grant was estimated on the date of the grant using the Black Scholes valuation model. Stock options generally vest ratably over four years, with vesting beginning one year from the date of grant, and generally expire 10 years from the date of grant. The service period for certain retiree eligible participants is accelerated. The assumptions used in determining the fair value of the stock options granted in the respective periods were as follows:

	Three Months Ended March 31,
	2024	2023
Weighted average fair value of grants	$63.74	$60.80
Dividend yield	1.09%	1.06%
Volatility	26.67%	27.19%
Risk-free interest rate	4.31%	4.12%

Restricted Stock

Restricted stock awards generally cliff vest after three years for employees and non-employee directors. The service period for certain retiree eligible participants is accelerated. Unvested restricted stock carries dividend and voting rights and the sale of the shares is restricted prior to the date of vesting. Dividends are paid on restricted stock awards and their fair value is equal to the market price of the Company’s stock at the date of the grant. A summary of the Company’s restricted stock activity as of March 31, 2024 and changes during the three months ended March 31, 2024 are presented in the following table:

As of March 31, 2024, there was $11.3 million of total unrecognized compensation cost related to restricted stock that is expected to be recognized over a weighted-average period of 1.1 years.

Cash-Settled Restricted Stock

The Company also maintains a cash-settled share-based compensation plan for certain employees. Cash-settled restricted stock awards generally cliff vest after three years. The service period for certain retiree eligible participants is accelerated. Cash-settled restricted stock awards are recorded at fair value on a quarterly basis using the market price of the Company’s stock on the last day of the quarter. At March 31, 2024 and December 31, 2023, the Company had accrued $3.8 million and $4.2 million, respectively, for cash-settled restricted stock in Accrued expenses in the Condensed Consolidated Balance Sheets and had accrued $1.7 million and $2.9 million, respectively, for cash-settled restricted stock in Other noncurrent liabilities in the Condensed Consolidated Balance Sheets. These recurring fair value measurements are classified as Level 1 in the fair value hierarchy. Dividend equivalents are paid on certain cash-settled restricted stock awards. A summary of the Company’s unvested cash-settled restricted stock activity as of March 31, 2024 and changes during the three months ended March 31, 2024 are presented in the following table:

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the Condensed Consolidated Financial Statements and related notes in this quarterly report. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. The Company’s actual results and the timing of events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under Item 1A, “Risk Factors” in the Company’s most recent annual report on Form 10-K and under the heading “Cautionary Statement Under the Private Securities Litigation Reform Act” discussed elsewhere in this quarterly report.

This discussion includes certain non-GAAP financial measures that have been defined and reconciled to the most directly comparable financial measure prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) under the headings “Non-GAAP Disclosures” and “Free Cash Flow.” This discussion also includes Operating working capital, which has been defined under the heading “Liquidity and Capital Resources.” The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures prepared in accordance with U.S. GAAP. The financial results prepared in accordance with U.S. GAAP and the reconciliations from these results should be carefully evaluated.

Overview

IDEX is an applied solutions provider specializing in the manufacturing of fluid and metering technologies, health and science technologies and fire, safety and other diversified products built to customers’ specifications. IDEX’s products are sold in niche markets across a wide range of industries throughout the world. Accordingly, IDEX’s businesses are affected by levels of industrial activity and economic conditions in the U.S. and in other countries where it does business, as well as by the relationship of the U.S. dollar to other currencies. Levels of capacity utilization and capital spending in certain industries and overall industrial activity are important factors that influence the demand for IDEX’s products.

23

During the three months ended March 31, 2024, the Company delivered a solid operating performance. While some market softness carried over from 2023, largely within the Company’s Health & Science Technologies segment, resulting in lower sales volumes, the Company realized strong price/cost across its segments. Strong cash flow from operating activities of $156.6 million, an increase of 6% compared to the same prior year period, resulted in free cash flow of $136.6 million during the quarter.

Results of Operations

The following is a discussion and analysis of the Company’s results of operations for the three months ended March 31, 2024 compared with the three months ended March 31, 2023.

	Three Months Ended March 31,
(Dollars in millions, except per share amounts)	2024			2023			% / bps Change

Net income attributable to IDEX	$	121.4		$	139.8		(13	%)
Diluted earnings per common share attributable to IDEX	$	1.60		$	1.84		(13	%)

Net Sales

Net sales for the three months ended March 31, 2024 decreased 5% as compared to the same prior year period reflecting a 6% decrease in organic net sales, partially offset by a 1% increase in acquisitions, net of divestitures. The decrease in organic net sales was driven by lower volumes, largely as a result of market conditions in the Health & Science Technologies businesses, partially offset by price capture across all segments. In the three months ended March 31, 2024, net sales decreased 4% domestically and 6% internationally, and sales to customers outside the U.S. were approximately 50% of total sales in the first quarter of both 2024 and 2023.

Gross Profit and Gross Margin

Gross profit and Gross margin for the three months ended March 31, 2024 decreased primarily due to lower volume leverage and higher employee-related costs, partially offset by strong price/cost and favorable operational productivity.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three months ended March 31, 2024 increased primarily due to the $3.5 million impact from acquisitions, including amortization, net of divestitures.

Restructuring Expenses and Asset Impairments

Restructuring expenses and asset impairments increased in the three months ended March 31, 2024 primarily due to higher severance costs, which were incurred in conjunction with cost mitigation efforts as a result of market conditions, compared with the same period in 2023.

24

Other (Income) Expense - Net

Other (income) expense - net increased to $2.7 million of income in the first quarter of 2024 compared to $0.6 million of income during the same period in 2023. The increase was primarily due to higher foreign currency transaction gains during the current year period.

Interest Expense - Net

Interest expense - net for the three months ended March 31, 2024 decreased compared to the same period in 2023 due to a decrease in the amount of debt outstanding and higher interest earned on cash balances in 2024, partially offset by increases in interest rates on outstanding debt, which increased interest expense by approximately $0.8 million.

Income Taxes

The Company’s provision for income taxes is based upon estimated annual tax rates for the year applied to federal, state and foreign income. The provision for income taxes decreased to $33.2 million for the three months ended March 31, 2024 from $40.0 million during the same period in 2023. The effective tax rate decreased to 21.5% for the three months ended March 31, 2024 from 22.2% during the same period in 2023 primarily due to benefits related to the finalization of tax impacts with taxing authorities of a previously recorded legal entity restructuring.

In October 2021, members of the Organization for Economic Co-operation and Development (“OECD”) and G20 Inclusive Framework on Base Erosion and Profit Shifting agreed to a two-pillar solution to address the tax challenges associated with the digitalization of the economy. In December 2021, the OECD released the Pillar Two Model Rules (“Pillar Two”), which define the global minimum tax and call for the taxation of large corporations at a minimum rate of 15%. Although it is uncertain when and how the rules will be fully enacted into law, based on our initial assessment, nearly all of the jurisdictions in which the Company operates have an effective tax rate above the 15% threshold. Therefore, the Company does not expect a material impact from the Pillar Two income tax rules.

Results of Reportable Business Segments

The Company has three reportable segments: Fluid & Metering Technologies (“FMT”), Health & Science Technologies (“HST”) and Fire & Safety/Diversified Products (“FSDP”). For a detailed description of the operations within each segment, refer to Note 3, “Business Segments,” in the Notes to Condensed Consolidated Financial Statements. Management’s primary measurements of segment performance are Net sales, adjusted earnings before interest, income taxes, depreciation and amortization (“Adjusted EBITDA”) and Adjusted EBITDA margin.

The table below illustrates the share of Net sales and Adjusted EBITDA contributed by each segment on the basis of total segments (not total Company) for the three months ended March 31, 2024.

	Three Months Ended March 31, 2024
	FMT		HST		FSDP		IDEX
Net sales	39	%	39	%	22	%	100	%
Adjusted EBITDA(1)	44	%	34	%	22	%	100	%

(1) Segment Adjusted EBITDA excludes the impact of unallocated corporate costs of $29.9 million for the three months ended March 31, 2024.

•Organic net sales for the three months ended March 31, 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 three months ended March 31, 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 three months ended March 31, 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 three months ended March 31, 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.

•Organic net sales for the three months ended March 31, 2024 were positively impacted by price capture across all markets. Volumes were flat period over period.

•Organic Adjusted EBITDA margin for the three months ended March 31, 2024 increased primarily due to strong price/cost and lower discretionary spending, partially offset by higher employee-related costs.

Liquidity and Capital Resources

Liquidity

Based on management’s current expectations and currently available information, the Company believes current cash, cash from operations and cash available under the Revolving Facility will be sufficient to meet its operating cash requirements, planned capital expenditures, interest and principal payments on all borrowings, pension and postretirement funding requirements, share repurchases and quarterly dividend payments to holders of the Company’s common stock for the foreseeable future. Additionally, in the event that suitable businesses are available for acquisition upon acceptable terms, the Company may obtain all or a portion of the financing for these acquisitions through the incurrence of additional borrowings.

Select key liquidity metrics at March 31, 2024 are as follows:

(In millions)	March 31, 2024
Working capital	$	1,093.9
Current ratio	3.4 to 1
Cash and cash equivalents	$	616.3
Cash held outside of the United States	475.0
Revolving Facility capacity	$	800.0
Borrowings	78.8
Letters of credit	3.4
Revolving Facility availability	$	717.8

The Company believes that additional borrowings through various financing alternatives remain available, if required.

Operating Working Capital

Operating working capital, calculated as Receivables - net plus Inventories - net minus Trade accounts payable, is used by management as a measurement of operational results as well as the short-term liquidity of the Company. The following table details Operating working capital as of March 31, 2024 and December 31, 2023:

(In millions)	March 31, 2024		December 31, 2023		Change		Organic Change
Receivables - net	$	437.9	$	427.8	$	10.1	$	13.9
Inventories - net	426.0		420.8		5.2		9.4
Less: Trade accounts payable	185.8		179.7		6.1		8.2
Operating working capital	$	678.1	$	668.9	$	9.2	$	15.1

27

Operating working capital increased $9.2 million to $678.1 million at March 31, 2024. Acquisitions and foreign currency translation decreased Operating working capital by $5.9 million during the first quarter of 2024. Apart from these items, receivables increased due to strong price capture, which more than offset the impact of lower volumes; inventories increased to support planned production; and accounts payable increased as a result of higher inventory purchases.

Cash Flow Summary

The following table is derived from the Condensed Consolidated Statements of Cash Flows:

	Three Months Ended March 31,
(In millions)	2024		2023
Net cash flows provided by (used in):
Operating activities	$	156.6	$	147.9
Investing activities	(20.0)		(29.2)
Financing activities	(41.0)		(45.2)

Operating Activities

Cash flows provided by operating activities increased $8.7 million to $156.6 million in the three months ended March 31, 2024 primarily due to lower cash payments for variable compensation in 2024 compared to the prior year, partially offset by lower earnings in 2024 compared to the prior year.

Investing Activities

Cash flows used in investing activities decreased during the three months ended March 31, 2024 primarily due to the lower capital expenditures of $20.0 million in 2024 as compared with $26.6 million in the three months ended March 31, 2023.

Financing Activities

Cash flows used in financing activities primarily consisted of dividends of $48.5 million and $45.5 million paid to common shareholders during the three months ended March 31, 2024 and March 31, 2023, respectively.

Free Cash Flow

The Company believes free cash flow, a non-GAAP measure, is an important measure of performance because it provides a measurement of cash generated from operations that is available for payment obligations such as operating cash requirements, planned capital expenditures, interest and principal payments on all borrowings, pension and postretirement funding requirements and quarterly dividend payments to holders of the Company’s common stock as well as for funding acquisitions and share repurchases. Free cash flow is calculated as cash flows provided by operating activities less capital expenditures.

The following table reconciles cash flows provided by operating activities to free cash flow:

	Three Months Ended March 31,
(Dollars in millions)	2024			2023
Cash flows provided by operating activities	$	156.6		$	147.9
Less: capital expenditures	20.0			26.6
Free cash flow	$	136.6		$	121.3
Free cash flow as a percent of adjusted net income attributable to IDEX	95.4		%	76.5		%

The increase in free cash flow for the three months ended March 31, 2024 as compared to 2023 is due to lower cash payments for variable compensation in 2024 as discussed above and lower capital expenditures in 2024 compared with the three months ended March 31, 2023.

28

Cash Requirements

Capital Expenditures

Capital expenditures generally include machinery and equipment that support growth and improved productivity, tooling, business system technology, replacement of equipment and investments in new facilities. The Company believes it has sufficient operating cash flows to continue to meet current obligations and invest in planned capital expenditures. Cash flows from operations were more than adequate to fund capital expenditures of $20.0 million and $26.6 million in the first three months of 2024 and 2023, respectively.

Share Repurchases

There were no share repurchases during the three months ended March 31, 2024 and 2023. As of March 31, 2024, the amount of share repurchase authorization remaining was $539.7 million. For additional information regarding the Company’s share repurchase program, refer to Note 11, “Share Repurchases,” in the Notes to Condensed Consolidated Financial Statements.

Dividends

Total dividend payments to common shareholders were $48.5 million during the three months ended March 31, 2024 compared with $45.5 million during the three months ended March 31, 2023.

Covenants

The key financial covenants that the Company is required to maintain in connection with the Revolving Facility, the Term Facility, the 3.37% Senior Notes and the 5.13% Senior Notes, are a minimum interest coverage ratio of 3.0 to 1 and a maximum leverage ratio of 3.50 to 1. At March 31, 2024, the Company was in compliance with these financial covenants, as the Company’s interest coverage ratio was 18.48 to 1 for covenant calculation purposes and the leverage ratio was 1.49 to 1. There are no financial covenants relating to the 2.625% Senior Notes or the 3.00% Senior Notes; however, both are subject to cross-default provisions.

Credit Ratings

The Company’s credit ratings, which were independently developed by the following credit agencies, are detailed below:

•S&P Global Ratings reaffirmed the Company’s corporate credit rating of BBB (stable outlook) in August 2023.

•Moody’s Investors Service affirmed the Company’s corporate credit rating of Baa2 (stable outlook) in December 2021.

•Fitch Ratings reaffirmed the Company’s corporate credit rating of BBB+ (stable outlook) in April 2023.

Off-Balance Sheet Arrangements

The Company had $21.4 million of letters of credit as of March 31, 2024, primarily issued as security for insurance and other performance obligations. Of the $21.4 million of letters of credit, only $3.4 million reduced the Company’s borrowing capacity under the Revolving Facility as of March 31, 2024.

Except as disclosed above, the Company has no off-balance sheet arrangements that currently have or are reasonably likely to have a material effect on the Company’s consolidated financial condition, changes in financial condition, results of operations, liquidity, capital expenditures or capital resources.

29

Critical Accounting Estimates

As discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, the preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. There have been no changes to the Company’s critical accounting estimates described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

30

Non-GAAP Disclosures

Set forth below are reconciliations of Organic net sales, Adjusted gross profit, Adjusted gross margin, Adjusted net income attributable to IDEX, Adjusted diluted earnings per share (“EPS”) attributable to IDEX, Consolidated Adjusted earnings before interest, income taxes, depreciation and amortization (“Adjusted EBITDA”) and Consolidated Adjusted EBITDA margin to their respective most directly comparable U.S. GAAP measure. Management uses these metrics to measure performance of the Company since they exclude items that are not reflective of ongoing operations, as identified in the reconciliations below. Management also supplements its U.S. GAAP financial statements with adjusted information to provide investors with greater insight, transparency and a more comprehensive understanding of the information used by management in its financial and operational decision making.

Management uses Adjusted EBITDA as its principal measure of segment performance, and believes it is a useful indicator of the strength and performance of the Company and its segments’ ongoing business operations, as well as a way for investors to evaluate and compare operating performance and value companies within the Company’s industry. Management believes that Adjusted EBITDA margin is useful for the same reason as Adjusted EBITDA. The definition of Adjusted EBITDA used here may differ from that used by other companies.

This report also references free cash flow. This non-GAAP measure is discussed and reconciled to its most directly comparable GAAP measure in the section above titled “Free Cash Flow.”

The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures prepared in accordance with U.S. GAAP. Due to rounding, numbers presented throughout this and other documents may not add up or recalculate precisely. The financial results prepared in accordance with U.S. GAAP and the reconciliations from these results should be carefully evaluated.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes with respect to market risks disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

Item 4.    Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As required by SEC Rule 13a-15(b), the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2024.

There has been no change in the Company’s internal control over financial reporting during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.    Legal Proceedings

The Company and its subsidiaries are party to legal proceedings arising in the ordinary course of business as described in Note 14 in Part I, Item 1, “Commitments and Contingencies,” and such disclosure is incorporated by reference into this Item 1. “Legal Proceedings.”

The Company’s threshold for disclosing material environmental legal proceedings involving a government authority where potential monetary sanctions are involved is $1.0 million.

In addition, the Company and six of its subsidiaries are presently named as defendants in a number of lawsuits claiming various asbestos-related personal injuries, allegedly as a result of exposure to products manufactured with components that contained asbestos. These components were acquired from third party suppliers and were not manufactured by the Company or any of the defendant subsidiaries. To date, the majority of the Company’s settlements and legal costs, except for costs of coordination, administration, insurance investigation and a portion of defense costs, have been covered in full by insurance, subject to applicable deductibles. However, the Company cannot predict whether and to what extent insurance will be available to continue to cover these settlements and legal costs, or how insurers may respond to claims that are tendered to them. Asbestos-related claims have been filed in jurisdictions throughout the United States and the United Kingdom. Most of the claims resolved to date have been dismissed without payment. The balance of the claims have been settled for various immaterial amounts. Only one case has been tried, resulting in a verdict for the Company’s business unit. No provision has been made in the financial statements of the Company, other than for insurance deductibles in the ordinary course, and the Company does not currently believe the asbestos-related claims will have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

Item 1A. Risk Factors

There have been no material changes with respect to risk factors disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

(1)On March 17, 2020, the Company’s Board of Directors approved an increase of $500.0 million in the authorized level of repurchases of common stock. This approval is in addition to the prior repurchase authorization of the Board of Directors of $300.0 million on December 1, 2015. These authorizations have no expiration date.

Item 5.    Other Information

During the quarter ended March 31, 2024, none of the Company’s directors or executive officers adopted or terminated any contract, instruction or written plan for the purchase or sale of Company securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement” as defined in Item 408 of Regulation S-K under the Securities Exchange Act of 1934, as amended.

Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies

Basis of Presentation and Significant Accounting Policies

The Condensed Consolidated Financial Statements of IDEX Corporation (“IDEX” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) applicable to interim financial information and the instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended. The statements are unaudited but include all adjustments, consisting only of recurring items, except as noted, that the Company considers necessary for a fair presentation of the information set forth herein. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the entire year.

The Condensed Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations set forth in this report should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Recently Issued Accounting Standards

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves the disclosures required for reportable segments in the Company’s annual and interim financial statements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024.

Business Combination and Asset Acquisition [Abstract]

Acquisitions

Acquisitions

All of the Company’s acquisitions of businesses have been accounted for under Accounting Standards Codification (“ASC”) 805, Business Combinations. Accordingly, the assets and liabilities of the acquired companies, after adjustments to reflect the fair values assigned to the assets and liabilities, have been included in the Condensed Consolidated Balance Sheets from their respective dates of acquisition. The results of operations of businesses acquired have been included in the Condensed Consolidated Statements of Income since their respective dates of acquisition. Supplemental pro forma information has not been provided as the acquisitions did not have a material impact on the Condensed Consolidated Financial Statements individually or in the aggregate.

The Company makes a preliminary allocation of the purchase price for each acquisition as of the acquisition date based on its understanding of the fair value of the acquired assets and assumed liabilities. These nonrecurring fair value measurements are classified as Level 3 in the fair value hierarchy. As the Company continues to obtain additional information, primarily related to the valuations of these assets and liabilities, and continues to integrate the newly acquired business, the Company will refine the estimates of fair value and more accurately allocate the purchase price through the completion of the measurement period, which is not to exceed one year from the date of acquisition. Only items identified as of the acquisition date are considered for subsequent adjustment.

Earnings Per Common Share

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

Diluted earnings per common share (“EPS”) attributable to IDEX is computed by dividing Net income attributable to IDEX by the weighted average number of common shares outstanding (basic) plus common stock equivalents outstanding (diluted) for the period. Common stock equivalents consist of restricted stock, performance share units and stock options, which have been included in the calculation of weighted average common shares outstanding using the treasury stock method.

ASC 260, Earnings Per Share (“ASC 260”), concludes that all outstanding unvested share-based payment awards that contain rights to non-forfeitable dividends participate in undistributed earnings with common shareholders. If awards are considered participating securities, the Company is required to apply the two-class method of computing basic and diluted earnings per share. The Company has determined that its outstanding shares of restricted stock are participating securities. Accordingly, Diluted EPS attributable to IDEX was computed using the two-class method prescribed by ASC 260.

Basic weighted average common shares outstanding reconciles to diluted weighted average common shares outstanding as follows:

	Three Months Ended March 31,
	2024	2023
Basic weighted average common shares outstanding	75.7	75.6
Dilutive effect of restricted stock, performance share units and stock options	0.2	0.3
Diluted weighted average common shares outstanding	75.9	75.9

Share-based payment awards of approximately 0.5 million and 0.2 million shares of common stock for the three months ended March 31, 2024 and 2023, respectively, were not included in the computation of Diluted EPS attributable to IDEX because the effect of their inclusion would have been antidilutive.

ASC 350, Goodwill and Other Intangible Assets (“ASC 350”), requires that goodwill be tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. Annually, on October 31, goodwill and other acquired intangible assets with indefinite lives are tested for impairment. Based on the results of the Company’s annual impairment test at October 31, 2023, all reporting units had fair values in excess of their carrying values. During the three months ended March 31, 2024, there were no events or circumstances that would have required an interim impairment test.

The following table provides the gross carrying value and accumulated amortization for each major class of intangible asset at March 31, 2024 and December 31, 2023:

	At March 31, 2024							At December 31, 2023

Total intangible assets	$	1,338.6	$	(369.5)	$	969.1		$	1,365.0	$	(353.2)	$	1,011.8

The Banjo and Akron Brass trade names are indefinite-lived intangible assets which are tested for impairment on an annual basis in accordance with ASC 350 or more frequently if events or changes in circumstances indicate that the assets might be impaired. Based on the results of the Company’s annual impairment test at October 31, 2023, these indefinite-lived intangible assets had fair values in excess of their carrying values. During the three months ended March 31, 2024, there were no events or circumstances that would have required an interim impairment test on these indefinite-lived intangible assets.

Amortization of intangible assets was $24.6 million and $23.6 million for the three months ended March 31, 2024 and 2023, respectively. Based on the intangible asset balances as of March 31, 2024, expected amortization expense for the remaining nine months of 2024 and for the years 2025 through 2028 is as follows:

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 entity’s own assumptions.

The following table summarizes the basis used to measure the Company’s financial assets (liabilities) at fair value on a recurring basis in the balance sheets at March 31, 2024 and December 31, 2023:

	Basis of Fair Value Measurements
	March 31, 2024		December 31, 2023
	Level 1		Level 1
Trading securities - mutual funds held in nonqualified SERP(1)	$	10.3	$	10.5
Available-for-sale securities - equities(2)	4.4		4.4

(1) The Supplemental Executive Retirement Plan (“SERP”) investment assets are offset by a SERP liability which represents the Company’s obligation to distribute SERP funds to participants. The SERP investment assets and liability are included in Other noncurrent assets and Other noncurrent liabilities, respectively, on the Condensed Consolidated Balance Sheets.

(2) The securities are included in Other current assets on the Condensed Consolidated Balance Sheets and are available for overnight cash settlement, if necessary, to fund current operations.

There were no transfers of assets or liabilities between Level 1 and Level 2 during the three months ended March 31, 2024 or the year ended December 31, 2023.

The carrying values of the Company’s cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value because of the short-term nature of these instruments.

The following table provides the fair value of the outstanding indebtedness described in Note 8, “Borrowings,” which is based on quoted market prices and current market rates for debt with similar credit risk and maturity, as well as the carrying value. These fair value measurements are classified as Level 2 within the fair value hierarchy since they are determined based upon significant inputs observable in the market, including interest rates on recent financing transactions to entities with a credit rating similar to the Company’s rating.

	March 31, 2024				December 31, 2023
	Fair Value		Carrying Amount		Fair Value		Carrying Amount
Total Borrowings, less unaccreted debt discount	$	1,239.7	$	1,329.9	$	1,203.5	$	1,332.2

Share-Based Compensation

3 Months Ended

Mar. 31, 2024

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

The Company typically grants equity awards annually at its regularly scheduled first quarter meeting of the Board of Directors based on the recommendation from the Compensation Committee.

The Company’s policy is to recognize compensation cost on a straight-line basis, assuming forfeitures, over the requisite service period for the entire award. Classification of share-based compensation cost within the Condensed Consolidated Statements of Income is consistent with the classification of cash compensation for the same employees.

Stock Options

Stock options granted under the Company’s plans are generally non-qualified and are granted with an exercise price equal to the market price of the Company’s stock on the date of grant. The fair value of each option grant was estimated on the date of the grant using the Black Scholes valuation model. Stock options generally vest ratably over four years, with vesting beginning one year from the date of grant, and generally expire 10 years from the date of grant. The service period for certain retiree eligible participants is accelerated. The assumptions used in determining the fair value of the stock options granted in the respective periods were as follows:

	Three Months Ended March 31,
	2024	2023
Weighted average fair value of grants	$63.74	$60.80
Dividend yield	1.09%	1.06%
Volatility	26.67%	27.19%
Risk-free interest rate	4.31%	4.12%
Expected life (in years)	4.60	4.50

A summary of the Company’s stock option activity as of March 31, 2024 and changes during the three months ended March 31, 2024 are presented in the following table:

	Shares	Weighted Average Price		Weighted-Average Remaining Contractual Term	Aggregate Intrinsic Value

Exercisable at March 31, 2024	605,708	$	166.99	5.91	$	46.7

As of March 31, 2024, there was $14.5 million of total unrecognized compensation cost related to stock options that is expected to be recognized over a weighted-average period of 1.6 years.

Restricted Stock

Restricted stock awards generally cliff vest after three years for employees and non-employee directors. The service period for certain retiree eligible participants is accelerated. Unvested restricted stock carries dividend and voting rights and the sale of the shares is restricted prior to the date of vesting. Dividends are paid on restricted stock awards and their fair value is equal to the market price of the Company’s stock at the date of the grant. A summary of the Company’s restricted stock activity as of March 31, 2024 and changes during the three months ended March 31, 2024 are presented in the following table:

Restricted Stock	Shares	Weighted-Average Grant Date Fair Value
Unvested at January 1, 2024	112,891	$	193.03
Granted	28,545	228.93
Vested	(15,035)	198.33
Forfeited	(3,395)	206.55
Unvested at March 31, 2024	123,006	$	200.34

As of March 31, 2024, there was $11.3 million of total unrecognized compensation cost related to restricted stock that is expected to be recognized over a weighted-average period of 1.1 years.

Cash-Settled Restricted Stock

The Company also maintains a cash-settled share-based compensation plan for certain employees. Cash-settled restricted stock awards generally cliff vest after three years. The service period for certain retiree eligible participants is accelerated. Cash-settled restricted stock awards are recorded at fair value on a quarterly basis using the market price of the Company’s stock on the last day of the quarter. At March 31, 2024 and December 31, 2023, the Company had accrued $3.8 million and $4.2 million, respectively, for cash-settled restricted stock in Accrued expenses in the Condensed Consolidated Balance Sheets and had accrued $1.7 million and $2.9 million, respectively, for cash-settled restricted stock in Other noncurrent liabilities in the Condensed Consolidated Balance Sheets. These recurring fair value measurements are classified as Level 1 in the fair value hierarchy. Dividend equivalents are paid on certain cash-settled restricted stock awards. A summary of the Company’s unvested cash-settled restricted stock activity as of March 31, 2024 and changes during the three months ended March 31, 2024 are presented in the following table:

Cash-Settled Restricted Stock	Shares	Weighted-Average Fair Value

As of March 31, 2024, there was $7.0 million of total unrecognized compensation cost related to cash-settled restricted shares that is expected to be recognized over a weighted-average period of 1.2 years.

Performance Share Units

The performance share units are market condition awards and have been assessed at fair value on the date of grant using a Monte Carlo simulation model. The assumptions used in determining the fair value of the performance share units granted in the respective periods were as follows:

	Three Months Ended March 31,
	2024	2023
Weighted average fair value of grants	$349.59	$308.18
Dividend yield	—%	—%
Volatility	22.23%	27.00%
Risk-free interest rate	4.45%	4.37%
Expected life (in years)	2.94	2.94

A summary of the Company’s performance share unit activity as of March 31, 2024 and changes during the three months ended March 31, 2024 are presented in the following table:

Performance Share Units	Shares	Weighted-Average Grant Date Fair Value
