(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 and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the entire year.

The Condensed Consolidated Financial Statements 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 reconciliation, 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. Adoption of this ASU should be applied prospectively, but may 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.

2. Acquisitions and Divestitures

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 that existed as of the acquisition date are considered for subsequent adjustment to the purchase price allocation.

On July 23, 2024, the Company entered into a definitive agreement to acquire Mott Corporation and its subsidiaries (“Mott”) for cash consideration of $1.0 billion, subject to customary adjustments.

STC

On December 14, 2023, the Company acquired STC Material Solutions (“STC”) in a stock acquisition. STC specializes in the design and manufacturing of technical ceramics and hermetic sealing products for critical applications in the semiconductor, aerospace and defense, industrial technology, medical technology and energy markets. Headquartered in St. Albans, Vermont, with additional operations in Santa Ana, California, STC operates in the Company’s Scientific Fluidics & Optics reporting unit within the Health & Science Technologies segment. STC was acquired for cash consideration of $200.4 million. The entire purchase price was funded with cash on hand. Goodwill and intangible assets recognized as part of this transaction were $104.2 million and $92.3 million, respectively. The goodwill is not deductible for tax purposes. The goodwill recorded for the acquisition reflects the strategic fit, revenue and earnings growth potential of the acquired business.

As of June 30, 2024, the preliminary allocation of the purchase price to the assets acquired and liabilities assumed, based on their estimated fair values at the acquisition date, is as follows:


	Total
Current assets, net of cash acquired	$	16.9
Property, plant and equipment	12.7
Goodwill	104.2
Intangible assets	92.3
Other noncurrent assets	2.9
Total assets acquired	229.0
Current liabilities	(5.5)
Deferred income taxes	(20.4)
Other noncurrent liabilities	(2.7)
Net assets acquired(1)	$	200.4

(1) The Company finalized the purchase price of STC, resulting in a $1.6 million downward adjustment to the purchase price. Funds were received by the Company in April 2024.

Acquired intangible assets consist of trade names, customer relationships and unpatented technology. The acquired intangible assets and weighted average amortization periods are as follows:


	Total		Weighted Average Life
Trade names	$	9.3	15
Customer relationships	63.0		15
Unpatented technology	20.0		11
Acquired intangible assets	$	92.3

Acquisition-Related Costs

The Company incurred acquisition-related costs of $2.5 million during both the three months ended June 30, 2024 and 2023 and $3.8 million and $3.6 million during the six months ended June 30, 2024 and 2023, respectively. These costs were recorded in Selling, general and administrative expenses and were related to completed, pending and potential transactions, including transactions that ultimately were not completed. The Company also recorded a $2.5 million fair value inventory step-up charge associated with the completed 2023 acquisition of STC in Cost of sales during the six months ended June 30, 2024. There were no step-up charges recorded during the three months ended June 30, 2024.

Divestitures

The Company periodically reviews its businesses relative to its core business. As such, from time to time, the Company may sell various businesses or assets for a variety of reasons. Any resulting gain or loss recognized due to divestitures is recorded within Gain on sale of business in the Condensed Consolidated Statements of Income.

On June 3, 2024, the Company completed the sale of Alfa Valvole, Srl (“Alfa Valvole”) for proceeds of $45.5 million, net of cash remitted, resulting in a gain on the sale of $4.6 million, net of a release of cumulative foreign currency translation losses of $5.5 million. There was no income tax impact associated with this transaction in the Condensed Consolidated Statements of Income due to the participation exemption of its consolidated group. The results of Alfa Valvole were reported in the Valves reporting unit within the Fluid & Metering Technologies segment through the date of disposition.

3. Business Segments

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 in all periods presented.

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:


	June 30, 2024		December 31, 2023
Billed receivables	$	407.6	$	408.1
Unbilled receivables	8.5		10.9
Total customer receivables	$	416.1	$	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.

The composition of deferred revenue was as follows:


	June 30, 2024		December 31, 2023
Deferred revenue – current	$	59.1	$	55.9
Deferred revenue – noncurrent	17.4		17.3
Total deferred revenue	$	76.5	$	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 granted prior to the adoption of the 2024 Incentive Award Plan are participating securities. Under the 2024 Incentive Award Plan, dividend rights for restricted stock are subject to the same vesting requirements as the underlying restricted stock awards. Consequently, any restricted stock awarded under the 2024 Incentive Plan will not be considered 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 June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Basic weighted average common shares outstanding	75.7	75.6	75.7	75.6
Dilutive effect of restricted stock, performance share units and stock options	0.2	0.3	0.2	0.3
Diluted weighted average common shares outstanding	75.9	75.9	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 June 30, 2024 and 2023, respectively, and 0.5 million and 0.2 million shares of common stock for the six months ended June 30, 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 six months ended June 30, 2024, there were no events or circumstances that would have required an interim impairment test.

Total intangible assets	$	1,306.8	$	(375.9)	$	930.9		$	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 six months ended June 30, 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 $23.9 million and $48.5 million for the three and six months ended June 30, 2024, respectively. Amortization of intangible assets was $23.2 million and $46.8 million for the three and six months ended June 30, 2023, respectively. Based on the intangible asset balances as of June 30, 2024, expected amortization expense for the remaining six months of 2024 and for the years 2025 through 2028 is as follows:


	Estimated Amortization

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 June 30, 2024 and December 31, 2023:


	Basis of Fair Value Measurements
	June 30, 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 and six months ended June 30, 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.


	June 30, 2024				December 31, 2023
	Fair Value		Carrying Amount		Fair Value		Carrying Amount
Total Borrowings, less unaccreted debt discount	$	1,158.9	$	1,303.9	$	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 six months ended June 30, 2024. During the six months ended June 30, 2023, the Company repurchased a total of 5,400 shares at a cost of $1.1 million, of which $0.1 million was settled in July 2023. As of June 30, 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 June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Weighted average fair value of grants	$62.41	$57.13	$63.72	$60.70
Dividend yield	1.13%	1.13%	1.09%	1.07%
Volatility	26.43%	27.20%	26.67%	27.19%
Risk-free interest rate	4.42%	3.81%	4.31%	4.12%
Expected life (in years)	4.60	4.50	4.60	4.50

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 June 30, 2024 and changes during the six months ended June 30, 2024 are presented in the following table:

As of June 30, 2024, there was $8.7 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 June 30, 2024 and December 31, 2023, the Company had accrued $3.3 million and $4.2 million, respectively, for cash-settled restricted stock in Accrued expenses in the Condensed Consolidated Balance Sheets and had accrued $1.8 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 June 30, 2024 and changes during the six months ended June 30, 2024 are presented in the following table:

14. Commitments and Contingencies

The Company and certain of its subsidiaries are involved in pending and threatened legal, regulatory and other proceedings arising in the ordinary course of business. These proceedings may pertain to matters such as product liability or contract disputes, and may also involve governmental inquiries, inspections, audits or investigations relating to issues such as tax matters, intellectual property, environmental, health and safety issues, governmental regulations, employment and other matters. Although the results of such legal proceedings cannot be predicted with certainty, the Company believes that the ultimate disposition of these matters will not have a material adverse effect, individually or in the aggregate, on the Company’s business, financial condition, results of operations or cash flows.

15. 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 and the effective tax rates were as follows:


	Three Months Ended June 30,						Six Months Ended June 30,
	2024			2023			2024			2023

Effective tax rate	21.2		%	22.4		%	21.4		%	22.3		%

The effective tax rate for the three and six months ended June 30, 2024 reflects the impact of the discrete benefits related to the finalization of prior years’ research and development tax incentives with taxing authorities in a foreign jurisdiction. The effective tax rate for the six months ended June 30, 2024 also reflects the discrete benefit related to the finalization of tax impacts of a previously recorded legal entity restructuring.

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 markets and overall industrial activity are important factors that influence the demand for IDEX’s products.

Second Quarter Highlights

Select key financial results for the three months ended June 30, 2024 when compared to the same period in the prior year are as follows:


	Three Months Ended June 30,

*These are non-GAAP measures. See the definitions of these non-GAAP measures and reconciliations to their most directly comparable GAAP financial measures under the headings “Non-GAAP Disclosures” and “Free Cash Flow.”

(1) There were no non-GAAP adjustments during the three months ended June 30, 2024 or 2023, respectively, to Gross profit or Gross margin.

During the three months ended June 30, 2024, the Company delivered solid operating performance, despite challenging market headwinds. Continued market softness, largely within the Health & Science Technologies segment, resulted in lower sales volumes, which were partly offset by strong price/cost and productivity across all segments.

Net Sales

Net sales for both the three and six months ended June 30, 2024 decreased 5% as compared to the same prior year periods. Organic net sales for the same periods decreased 4% and 5%, respectively, as a result of 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 June 30, 2024, net sales decreased 4% domestically and 5% internationally. In the six months ended June 30, 2024, net sales decreased 4% domestically and 6% internationally. Sales to customers outside the U.S. were approximately 50% of total sales in each of the three and six months ended June 30, 2024 and 2023.

Gross Profit and Gross Margin

Gross profit decreased for both the three and six months ended June 30, 2024, primarily due to lower volume leverage, unfavorable mix and higher employee-related costs, partially offset by strong price/cost and favorable operational productivity. Gross margin increased for the three months ended June 30, 2024 and was flat for the six months ended June 30, 2024. The negative impacts of lower volume leverage, unfavorable mix and higher-employee related costs on gross margin were offset by the positive impacts of strong price/cost and favorable operational productivity.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three and six months ended June 30, 2024 increased primarily due to the $2.1 million and $5.6 million impact from acquisitions, net of divestitures, including amortization, respectively, as well as increased professional services and discretionary spending as compared to the same prior year periods.

Restructuring Expenses and Asset Impairments

Restructuring expenses and asset impairments decreased in the three and six months ended June 30, 2024 primarily due to lower severance costs compared with the same periods in 2023. Severance costs were incurred in conjunction with cost mitigation efforts as a result of market conditions.

Table of Contents

Gain on Sale of Business

During the three and six months ended June 30, 2024, the Company completed the sale of Alfa Valvole, Srl (“Alfa Valvole”) for proceeds of $45.5 million, net of cash remitted, resulting in a gain on the sale of $4.6 million, net of a release of cumulative foreign currency translation losses of $5.5 million. For additional information regarding the divestiture of Alfa Valvole, refer to Note 2, “Acquisitions and Divestitures,” in the Notes to Condensed Consolidated Financial Statements.

Other Expense (Income) – Net

Other expense (income) – net for the three and six months ended June 30, 2024 benefited from the absence of a $7.7 million credit loss reserve on a note receivable from a collaborative partner that did not reoccur during 2024. Additionally, the current year periods benefited from a favorable impact of foreign currency transactions as compared to the same prior year periods.

Interest Expense – Net

Interest expense – net for the three and six months ended June 30, 2024 decreased compared to the same periods 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 $0.6 million and $1.4 million for the three and six months ended June 30, 2024, respectively.

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 effective tax rate was 21.2% and 21.4% for the three and six months ended June 30, 2024, respectively, as compared to 22.4% and 22.3% during the same periods in 2023, respectively. The decrease in effective tax rate during the three and six months ended June 30, 2024 was primarily due to benefits realized in the second quarter of 2024 related to the finalization of prior years’ research and development tax incentives with taxing authorities in a foreign jurisdiction. The decrease in the effective tax rate during the six months ended June 30, 2024 also reflected the finalization of tax impacts 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.

(1) Divestitures included Alfa Valvole, sold in June 2024.

•Organic net sales were flat and slightly down for the three and six months ended June 30, 2024, respectively, as compared to the same prior year periods. Both the quarter and year to date results were negatively impacted by lower volumes, primarily in the industrial market. The impact of lower volumes was offset by price capture in both the three and six months ended June 30, 2024.

•Adjusted EBITDA margin for the three and six months ended June 30, 2024 decreased primarily due to higher discretionary spending, lower volume leverage and higher employee-related costs, partially offset by strong price/cost and favorable operational productivity. The six months ended June 30, 2024 were also negatively impacted by unfavorable mix.

•Organic net sales for the three and six months ended June 30, 2024 were negatively impacted by lower volumes driven by continued broad based market softness, which began in the second half of 2023. This decrease was partially offset by price capture.

•Excluding the net accretive impact of acquisitions and divestitures, Adjusted EBITDA margin for the three and six months ended June 30, 2024 decreased primarily due to lower volume leverage, unfavorable mix and higher employee-related costs, partially offset by favorable operational productivity, strong price/cost and lower discretionary spending.

•Organic net sales for the three and six months ended June 30, 2024 were positively impacted by price capture across all markets, which more than offset the impact of slightly lower volumes as compared to the same prior year periods.

•Excluding the dilutive impact of foreign currency, Adjusted EBITDA margin for the three and six months ended June 30, 2024 decreased primarily due to higher employee-related costs and lower volume leverage, partially offset by strong price/cost. The three months ended June 30, 2024 also benefited from favorable operational productivity, while the six months ended June 30, 2024 were favorably impacted by mix.

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

Select key liquidity metrics at June 30, 2024 are as follows:


(In millions)	June 30, 2024
Working capital	$	1,152.1
Current ratio	3.4 to 1
Cash and cash equivalents	$	700.7
Cash held outside of the United States	558.8
Revolving Facility capacity	$	800.0
Borrowings	78.1
Letters of credit	2.7
Revolving Facility availability	$	719.2

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 June 30, 2024 and December 31, 2023:


(In millions)	June 30, 2024		December 31, 2023		Change		Organic Change
Receivables – net	$	426.2	$	427.8	$	(1.6)	$	11.9
Inventories – net	427.9		420.8		7.1		19.6
Less: Trade accounts payable	172.4		179.7		(7.3)		(0.9)
Operating working capital	$	681.7	$	668.9	$	12.8	$	32.4

Operating working capital increased $12.8 million to $681.7 million at June 30, 2024. Acquisitions, divestitures and foreign currency translation decreased Operating working capital by $19.6 million during the six months ended June 30, 2024. Apart from these items, receivables increased due to strong price capture, which more than offset the impact of lower volumes and inventories increased to support planned production.

Cash Flow Summary

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


	Six Months Ended June 30,
(In millions)	2024		2023
Net cash flows provided by (used in):
Operating activities	$	290.2	$	289.1
Investing activities	11.7		(176.6)
Financing activities	(118.2)		(92.0)

Operating Activities

Cash flows provided by operating activities increased $1.1 million to $290.2 million in the six months ended June 30, 2024 primarily due to lower cash payments including payments for variable compensation and lower tax payments in 2024 compared to the prior year, largely offset by lower earnings in 2024 compared to the prior year and higher investments in working capital driven by higher inventory purchases to support planned production and increased receivables due to strong price capture.

Investing Activities

Cash flows provided by investing activities increased during the six months ended June 30, 2024 as the six months ended June 30, 2024 included the proceeds received of $45.5 million from the sale of Alfa Valvole in June 2024. The six months ended June 30, 2023 included the purchase of Iridian Spectral Technologies for $110.3 million as well as the purchase of marketable securities of $19.1 million, which did not reoccur during the six months ended June 30, 2024. Additionally, the six months ended June 30, 2023 included higher capital expenditures of $48.2 million, as compared to $35.9 million in the six months ended June 30, 2024.

Financing Activities

Cash flows used in financing activities primarily consisted of dividends of $100.7 million and $93.9 million paid to common shareholders during the six months ended June 30, 2024 and 2023, respectively. Additionally, the Company repaid $25.0 million of the $50.0 million previously outstanding under the Term Facility during the six months ended June 30, 2024.

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:


	Six Months Ended June 30,
(Dollars in millions)	2024		2023
Cash flows provided by operating activities	$	290.2	$	289.1
Less: capital expenditures	35.9		48.2
Free cash flow	$	254.3	$	240.9

The increase in free cash flow for the six months ended June 30, 2024 as compared to 2023 is primarily due to lower capital expenditures in 2024 compared with the six months ended June 30, 2023.

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 recalculate precisely. The financial results prepared in accordance with U.S. GAAP and the reconciliations from these results should be carefully evaluated.

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.
