These statements may relate to, among other things, the Company’s business strategy, outlook and the assumptions underlying these expectations, plant and equipment capacity for future growth, planned production, anticipated future acquisition behavior and capital deployment, inventory recalibration and future order stabilization and lead time, expectations regarding market sector contraction, recovery, stabilization or growth, availability and sufficiency of cash and financing alternatives, the anticipated benefits of the Company’s recent acquisitions, and are indicated by words or phrases such as “anticipates,” “estimates,” “plans,” “guidance,” “expects,” “projects,” “forecasts,” “should,” “could,” “will,” “management believes,” “the Company believes,” “the Company intends” and similar words or phrases. These statements are subject to inherent uncertainties and risks that could cause actual results to differ materially from those anticipated at the date of this report.

The risks and uncertainties include, but are not limited to, the following: levels of industrial activity and economic conditions in the U.S. and other countries around the world, including uncertainties in the financial markets; pricing pressures, including inflation and rising interest rates, and other competitive factors and levels of capital spending in certain industries; the impact of catastrophic weather events, natural disasters and public health threats; economic and political consequences resulting from terrorist attacks and wars; the Company’s ability to make acquisitions and to integrate and operate acquired businesses on a profitable basis; cybersecurity incidents; the relationship of the U.S. dollar to other currencies and its impact on pricing and cost competitiveness; political and economic conditions in foreign countries in which the Company operates; developments with respect to trade policy and tariffs; interest rates; capacity utilization and the effect this has on costs; labor markets; supply chain conditions; market conditions and material costs; risks related to environmental, social and corporate governance issues, including those related to climate change and sustainability; and developments with respect to contingencies, such as litigation and environmental matters.

Additional factors that could cause actual results to differ materially from those reflected in the forward-looking statements include, but are not limited to, the risks discussed in the “Risk Factors” section included in the Company’s most recent annual report on Form 10-K and the Company’s subsequent quarterly reports filed with the Securities and Exchange Commission (“SEC”) and the other risks discussed in the Company’s filings with the SEC.

(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 nine months ended September 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. Adoption of the standard is not expected to have a material impact on the Company’s Consolidated Financial Statements, but will require additional segment expense disclosures when adopted in the Company’s Form 10-K for the year ending December 31, 2024 and in periodic reports thereafter.

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 Company’s financial statement 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 June 3, 2024, the Company completed the sale of Alfa Valvole, Srl (“Alfa Valvole”) for proceeds of $45.1 million, net of cash remitted, resulting in an initial gain on the sale of $4.6 million, net of a release of cumulative foreign currency translation losses of $5.5 million.

Disaggregation of Revenue

The Company has a comprehensive offering of products, including technologies, built to customers’ specifications that are sold in niche markets throughout the world. The Company disaggregates revenue from contracts with customers by reporting unit and geographical region for each segment as the Company believes it best depicts how the amount, nature, timing and uncertainty of its revenue and cash flows are affected by economic factors. Revenue, presented as Net sales on the Condensed Consolidated Statements of Income, was attributed to geographical region based on the location of the customer. The following tables present revenue disaggregated by reporting unit and geographical region.

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.

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. Accordingly, Diluted EPS attributable to IDEX was computed using the two-class method prescribed by ASC 260. 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.

Basic weighted average common shares outstanding reconciles to diluted weighted average common shares outstanding as follows:
 Three Months Ended September 30,Nine Months Ended September 30,
 2024202320242023
Basic weighted average common shares outstanding75.7 75.6 75.7 75.6 
Dilutive effect of restricted stock, performance share units and stock options0.2 0.3 0.2 0.3 
Diluted weighted average common shares outstanding75.9 75.9 75.9 75.9 

Share-based payment awards of approximately 0.5 million shares of common stock for both the three and nine months ended September 30, 2024 and 0.2 million shares of common stock for both the three and nine months ended September 30, 2023 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 nine months ended September 30, 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 nine months ended September 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 $26.5 million and $75.0 million for the three and nine months ended September 30, 2024, respectively. Amortization of intangible assets was $23.8 million and $70.6 million for the three and nine months ended September 30, 2023, respectively. Based on the intangible asset balances as of September 30, 2024, expected amortization expense for the remaining three months of 2024 and for the years 2025 through 2028 is as follows:

(1) As of September 30, 2024, the $100.0 million 3.37% Senior Notes, due in June 2025, have been classified as Long-term borrowings on the Condensed Consolidated Balance Sheets. The Company has the ability and intent to either refinance or repay these Notes using the available borrowing capacity of the Revolving Facility, due November 2027.

(2) During the third quarter of 2024, the Company drew down an aggregate amount of $279.3 million under the Revolving Facility to finance a portion of Company’s acquisition of Mott. At September 30, 2024, there was $360.6 million outstanding under the Revolving Facility and $2.7 million of outstanding letters of credit, resulting in a net available borrowing capacity under the Revolving Facility of approximately $436.7 million. The weighted-average interest rate for borrowings outstanding under the Revolving Facility was 4.72% and 4.22% as of September 30, 2024 and December 31, 2023, respectively. During October 2024, the Company repaid $69.1 million of the $360.6 million outstanding under the Revolving Facility.

(3) The weighted-average interest rate for borrowings outstanding under the Term Facility was 6.55% and 6.22% as of September 30, 2024 and December 31, 2023, respectively. During the second quarter of 2024, the Company repaid $25.0 million of the $50.0 million previously outstanding under the Term Facility. During October 2024, the Company repaid the remaining $25.0 million outstanding under the Term Facility.

At September 30, 2024, the Company was in compliance with the covenants contained in the credit agreement associated with the Revolving Facility as well as other long-term debt agreements.

Issuance of 4.950% Senior Notes due 2029

On August 21, 2024, the Company completed an underwritten public offering of $500.0 million in aggregate principal amount of its 4.950% Senior Notes. The 4.950% Senior Notes bear interest at a rate of 4.950% per annum, which is payable semi-annually in arrears during the first and third quarters of the year, beginning in the first quarter of 2025. The 4.950% Senior Notes will mature on September 1, 2029. The 4.950% Senior Notes are senior, unsecured obligations of the Company and (i) rank equal in right of payment to all of the Company’s existing and future senior unsecured indebtedness, (ii) rank senior in right of payment to all of the Company’s existing and future subordinated indebtedness, and (iii) rank effectively subordinated in right of payment to the Company’s future secured indebtedness. The net proceeds from the 4.950% Senior Notes offering were approximately $495.0 million, after deducting the underwriting discount and offering expenses paid and payable by the Company. The Company used the net proceeds from the offering, together with the Revolving Facility borrowings discussed above and cash on hand, to fund the Mott acquisition and pay related fees and expenses.

The Company may redeem all or a portion of the 4.950% Senior Notes at any time prior to maturity at the redemption prices set forth in the Supplemental Indenture governing the 4.950% Senior Notes (the “Indenture”). The terms of the 4.950% Senior Notes also require the Company to make an offer to repurchase all or a portion of the 4.950% Senior Notes (unless otherwise redeemed) upon a “Change of Control Triggering Event” (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. The 4.950% Senior Notes are not subject to any financial covenants under the Indenture; however, they are subject to cross-acceleration provisions.

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 September 30, 2024 and December 31, 2023:

Basis of Fair Value Measurements
 September 30, 2024December 31, 2023
 Level 1Level 1
Trading securities - mutual funds held in nonqualified SERP(1)
$10.4 $10.5 
Available-for-sale securities - equities(2)
— 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 nine months ended September 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

There were no share repurchases during the nine months ended September 30, 2024. During the nine months ended September 30, 2023, the Company repurchased a total of 5,400 shares at a cost of $1.1 million. As of September 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:

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 September 30, 2024 and December 31, 2023, the Company had accrued $3.7 million and $4.2 million, respectively, for cash-settled restricted stock in Accrued expenses in the Condensed Consolidated Balance Sheets and had accrued $2.5 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.

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 income as well as state and foreign income in various jurisdictions, permanent differences between book and tax items, tax credits and the Company’s change in relative income in each jurisdiction. The provision for income taxes and the effective tax rates for the periods presented were as follows:

Three Months Ended September 30,Nine Months Ended September 30,
2024202320242023
Income before income taxes$154.4 $261.8 $488.1 $620.1 
Provision for income taxes35.5 52.8 106.7 132.8 
Effective tax rate22.9 %20.2 %21.9 %21.4 %

The three months ended September 30, 2024 had no material discrete tax items impacting the effective tax rate. The nine months ended September 30, 2024 benefited from the finalization of prior years’ research and development tax incentives with taxing authorities in a foreign jurisdiction and the finalization of tax impacts of a previously recorded legal entity restructuring. Both the three and nine months ended September 30, 2023 benefited from the finalization of the impact of research expenditure capitalization on the foreign derived intangible income deduction and the reduction of Global Intangible Low-Tax Income as a result of the tax amortization of goodwill related to the acquisition of Muon B.V. and its subsidiaries.

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

During the three months ended September 30, 2024, the Company delivered solid operating performance, despite continued challenging market headwinds. Market softness, largely within the Health & Science Technologies segment, resulted in lower sales volumes, which were partly offset by price/cost and productivity across all segments. On September 5, 2024, the Company completed the previously-announced acquisition of Mott Corporation and its subsidiaries (“Mott”), expanding the Company’s applied material science technology capabilities in high-value end markets. For additional information, refer to Note 2, “Acquisitions and Divestitures” in the Notes to Condensed Consolidated Financial Statements and the “Liquidity and Capital Resources” section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations.

(1)Activity recorded during the three months ended September 30, 2024 represents the finalization of the gain on the sale of Alfa Valvole, Srl resulting in a $0.6 million downward adjustment during the third quarter of 2024.

Net Sales

Net sales for the three and nine months ended September 30, 2024 increased 1% and decreased 3%, respectively, as compared to the same prior year periods. Organic net sales for the three and nine months ended September 30, 2024 were flat and decreased 3%, respectively, which reflected lower volumes, largely as a result of continued unfavorable market conditions in the Health & Science Technologies businesses. Price capture across all segments offset lower volumes during the three months ended September 30, 2024, but only partially offset lower volumes for the nine months ended September 30, 2024.

In the three months ended September 30, 2024, net sales decreased 1% domestically and increased 2% internationally. In the nine months ended September 30, 2024, net sales decreased 3% domestically and 3% internationally. Sales to customers outside the U.S. were approximately 50% of total sales in each of the three and nine months ended September 30, 2024 and 2023.

Gross Profit and Gross Margin

Gross profit and gross margin for the three and nine months ended September 30, 2024 were positively impacted by strong price/cost and favorable operational productivity and were negatively impacted by higher employee-related costs, unfavorable mix and lower volume leverage. Gross profit and gross margin for the nine months ended September 30, 2024 were both favorably impacted by lower discretionary spending.

27
Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three and nine months ended September 30, 2024 increased primarily due to the $5.6 million and $11.4 million impact from acquisitions, net of divestitures, including amortization, respectively, as well as higher employee-related costs and increased discretionary spending and transaction expenses as compared to the same prior year periods.

Restructuring Expenses and Asset Impairments

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

Gain on Sale of Business

During the nine months ended September 30, 2024, the Company completed the sale of Alfa Valvole, Srl (“Alfa Valvole”) for proceeds of $45.1 million, net of cash remitted, resulting in an initial gain on the sale of $4.6 million, net of a release of cumulative foreign currency translation losses of $5.5 million. During the three months ended September 30, 2024, the gain on the sale of Alfa Valvole was finalized, resulting in a downward adjustment to the gain on sale of $0.6 million for a final gain on sale of $4.0 million. During the three and nine months ended September 30, 2023, the Company completed the sale of Micropump, Inc. (“Micropump”) for proceeds of $110.3 million, net of cash remitted, resulting in a pre-tax gain on the sale of $93.8 million. For additional information regarding the divestitures of Alfa Valvole and Micropump, refer to Note 2, “Acquisitions and Divestitures,” in the Notes to Condensed Consolidated Financial Statements.

Other Expense (Income) – Net

Other expense (income) – net decreased in the three months ended September 30, 2024 primarily due to the unfavorable impact of foreign currency transactions as compared to the same prior year periods. Other expense (income) – net for the nine months ended September 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.

Interest Expense – Net

Interest expense – net for the three and nine months ended September 30, 2024 decreased compared to the same periods in 2023 due to higher interest earned on cash balances in 2024, which increased approximately $3.2 million and $7.0 million, respectively. This benefit was offset by incremental interest expense during the three months ended September 30, 2024 due to a net increase in debt outstanding throughout the period, while the nine months ended September 30, 2024 was further favorably impacted by lower interest expense due to a net decrease in debt outstanding through the period, primarily on the Term Facility.
Income Taxes

The effective tax rate was 22.9% and 21.9% for the three and nine months ended September 30, 2024, respectively, as compared to 20.2% and 21.4% during the same periods in 2023, respectively. One-time discrete tax benefits lowered the effective tax rates during nine months ended September 30, 2024 and both the three and nine months ended September 30, 2023. The three months ended September 30, 2024 did not benefit from these one-time items. For additional information, refer to Note 15, “Income Taxes,” in the Notes to Condensed Consolidated Financial Statements.

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 the Company’s 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 13, “Business Segments and Geographic Information,” in the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. Management’s 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 and nine months ended September 30, 2024.

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

•Organic net sales were positively impacted by price capture during the three and nine months ended September 30, 2024. Volumes were relatively flat during the three months ended September 20,2024 as improvement in the industrial market and strength in water were offset by both a down agriculture cycle and softness in the energy market. During the nine months ended September 30, 2024, lower volumes, driven primarily by softness in agriculture, partially offset the benefit of price capture.
•Excluding the accretive impact of divestitures, Adjusted EBITDA margin for the three and nine months ended September 30, 2024 decreased primarily due to higher employee-related costs, higher discretionary spending and unfavorable mix, partially offset by price/cost. The nine months ended September 30, 2024 were also negatively impacted by lower volumes, which were more than offset by favorable operational productivity.

(1) Acquisitions included Iridian Spectral Technologies acquired in May 2023, STC Material Solutions acquired in December 2023 and Mott acquired in September 2024. Divestitures included Micropump sold in August 2023 and Novotema, SpA sold in December 2023.
•Organic net sales for the three and nine months ended September 30, 2024 were negatively impacted by lower volumes driven by continued broad based market softness in 2024. This decrease was partially offset by price capture.
•Excluding the net accretive impact of acquisitions and divestitures, Adjusted EBITDA margin for the three and nine months ended September 30, 2024 decreased primarily due to lower volume, higher employee-related costs and unfavorable mix, partially offset by price/cost, favorable operational productivity and lower discretionary spending.

•Organic net sales for the three and nine months ended September 30, 2024 were positively impacted by price capture as compared to the same prior year periods. Key growth initiatives and strength in the aerospace market more than offset the cyclical nature of project sales in our North American dispensing business during the three months ended
30
September 30, 2024, resulting in higher volumes. Volumes were relatively flat during the nine months ended September 30, 2024 as growth initiatives were mostly offset by lower North American dispensing volumes.
•Adjusted EBITDA margin decreased slightly for the three and nine months ended September 30, 2024. Positive price/cost offset higher employee related costs during both periods. Additionally, unfavorable mix negatively impacted the three months ended September 30, 2024.

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.

Mott was acquired during the third quarter of 2024 for cash consideration of $986.2 million, net of cash acquired of $3.1 million. The acquisition was funded using a combination of cash on hand of $211.9 million, borrowings under the Company’s Revolving Facility of $279.3 million, and the net proceeds from the issuance of the 4.950% Senior Notes of $495.0 million. For additional information regarding the borrowings under the Company’s Revolving Facility and the 4.950% Senior Notes, refer to Note 8, “Borrowings,” in the Notes to Condensed Consolidated Financial Statements.

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 September 30, 2024 and December 31, 2023:

(In millions)September 30, 2024December 31, 2023ChangeOrganic Change

Operating working capital$752.9 $668.9 $84.0 $20.0 

31
Operating working capital increased $84.0 million to $752.9 million at September 30, 2024. Acquisitions, divestitures and foreign currency translation increased Operating working capital by $64.0 million during the nine months ended September 30, 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 and timing of payments.

Cash Flow Summary

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

Nine Months Ended September 30,
(In millions)20242023Change
Net cash flows provided by (used in):
Operating activities$495.5 $515.7 $(20.2)
Investing activities(991.8)(90.0)(901.8)
Financing activities606.7 (286.7)893.4 

Operating Activities

Cash flows provided by operating activities decreased $20.2 million in the nine months ended September 30, 2024 as compared to the same prior year period primarily due to lower earnings in 2024 compared to the prior year and higher investments in operating working capital driven by higher inventory purchases to support planned production and increased receivables due to strong price capture, partially offset by lower cash payments including payments for taxes and variable compensation in 2024 compared to the prior year.

Investing Activities

Cash flows used in investing activities increased $901.8 million during the nine months ended September 30, 2024 as compared to the prior year period. The net impact of acquisitions and divestitures increased cash used in investing activities $939.4 million during the nine months ended September 30, 2024 as compared to the same prior year period, primarily related to the acquisition of Mott during the third quarter of 2024. This increase in cash outflows was partially offset by the absence of purchases of marketable securities from the prior year period and lower capital expenditures, which decreased cash used in investing activities by $24.6 million and $18.7 million, respectively, as compared to the prior year period. For additional information on the Company’s acquisition and divestitures, refer to Note 2, “Acquisitions and Divestitures,” in the Notes to Condensed Consolidated Financial Statements.

Financing Activities

Cash flows from financing activities increased $893.4 million during the nine months ended September 30, 2024 as compared to the prior year period, primarily due to $774.8 million of net proceeds in connection with the financing of the acquisition of Mott. Additionally, repayments of the Term Facility were $125.0 million lower during the nine months ended September 30, 2024 than in the prior year period. These increases in cash flows were partly offset by slightly higher dividends paid to shareholders, which increased $10.7 million in the nine months ended September 30, 2024 as compared to the prior year period.

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.

32
The following table reconciles cash flows provided by operating activities to free cash flow:

Nine Months Ended September 30,
(Dollars in millions)20242023
Cash flows provided by operating activities$495.5 $515.7 
Less: capital expenditures 49.6 68.3 
Free cash flow$445.9 $447.4 


Cash Requirements

Subsequent Borrowings Activity

During October 2024, the Company repaid $69.1 million of the $360.6 million outstanding under the Revolving Facility as well as the remaining $25.0 million balance outstanding under the Term Facility at September 30, 2024.

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 $49.6 million and $68.3 million in the first nine months of 2024 and 2023, respectively.

Share Repurchases

There were no share repurchases during the nine months ended September 30, 2024. During the nine months ended September 30, 2023, the Company repurchased 5,400 shares at a cost of $1.1 million. As of September 30, 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 $153.0 million during the nine months ended September 30, 2024 compared with $142.3 million during the nine months ended September 30, 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 September 30, 2024, the Company was in compliance with these financial covenants, as the Company’s interest coverage ratio was 18.19 to 1 for covenant calculation purposes and the leverage ratio was 2.39 to 1. There are no financial covenants relating to the 2.625% Senior Notes, the 3.00% Senior Notes and the 4.950% Senior Notes; however, all are subject to cross-acceleration 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 September 2024.

•Moody’s Investors Service affirmed the Company’s corporate credit rating of Baa2 (stable outlook) in August 2024.

•Fitch Ratings reaffirmed the Company’s corporate credit rating of BBB+ (stable outlook) in June 2024.

33
Off-Balance Sheet Arrangements

The Company had $47.0 million of letters of credit as of September 30, 2024, primarily issued as security for insurance and other performance obligations. Of the $47.0 million of letters of credit, only $2.7 million reduced the Company’s borrowing capacity under the Revolving Facility as of September 30, 2024. The Company has restricted cash of $18.1 million as of September 30, 2024, which represents cash held as collateral for standby letters of credit issued by Mott and is required to keep the balance in a separate account for the duration of the letters of credit.

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.

Critical Accounting 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.

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.

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 September 30, 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,” in the Notes to Condensed Consolidated Financial Statements 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.

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 and nine months ended September 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. Adoption of the standard is not expected to have a material impact on the Company’s Consolidated Financial Statements, but will require additional segment expense disclosures when adopted in the Company’s Form 10-K for the year ending December 31, 2024 and in periodic reports thereafter.

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 Company’s financial statement disclosures.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]  
Acquisitions and Divestitures 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 June 3, 2024, the Company completed the sale of Alfa Valvole, Srl (“Alfa Valvole”) for proceeds of $45.1 million, net of cash remitted, resulting in an initial gain on the sale of $4.6 million, net of a release of cumulative foreign currency translation losses of $5.5 million. During the three months ended September 30, 2024, the gain on the sale of Alfa Valvole was finalized, resulting in a downward adjustment to the gain on sale of $0.6 million for a final gain on sale of $4.0 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.

Disaggregation of Revenue

The Company has a comprehensive offering of products, including technologies, built to customers’ specifications that are sold in niche markets throughout the world. The Company disaggregates revenue from contracts with customers by reporting unit and geographical region for each segment as the Company believes it best depicts how the amount, nature, timing and uncertainty of its revenue and cash flows are affected by economic factors. Revenue, presented as Net sales on the Condensed Consolidated Statements of Income, was attributed to geographical region based on the location of the customer. The following tables present revenue disaggregated by reporting unit and geographical region.

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:

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 granted prior to the adoption of the 2024 Incentive Award Plan are participating securities. Accordingly, Diluted EPS attributable to IDEX was computed using the two-class method prescribed by ASC 260. 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.

Basic weighted average common shares outstanding reconciles to diluted weighted average common shares outstanding as follows:
 Three Months Ended September 30,Nine Months Ended September 30,
 2024202320242023
Basic weighted average common shares outstanding75.7 75.6 75.7 75.6 
Dilutive effect of restricted stock, performance share units and stock options0.2 0.3 0.2 0.3 
Diluted weighted average common shares outstanding75.9 75.9 75.9 75.9 

Share-based payment awards of approximately 0.5 million shares of common stock for both the three and nine months ended September 30, 2024 and 0.2 million shares of common stock for both the three and nine months ended September 30, 2023 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 nine months ended September 30, 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 September 30, 2024 and December 31, 2023:

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 nine months ended September 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 $26.5 million and $75.0 million for the three and nine months ended September 30, 2024, respectively. Amortization of intangible assets was $23.8 million and $70.6 million for the three and nine months ended September 30, 2023, respectively. Based on the intangible asset balances as of September 30, 2024, expected amortization expense for the remaining three months of 2024 and for the years 2025 through 2028 is as follows:

The Company has the ability and intent to either refinance or repay these Notes using the available borrowing capacity of the Revolving Facility, due November 2027.

(2) During the third quarter of 2024, the Company drew down an aggregate amount of $279.3 million under the Revolving Facility to finance a portion of Company’s acquisition of Mott. At September 30, 2024, there was $360.6 million outstanding under the Revolving Facility and $2.7 million of outstanding letters of credit, resulting in a net available borrowing capacity under the Revolving Facility of approximately $436.7 million. The weighted-average interest rate for borrowings outstanding under the Revolving Facility was 4.72% and 4.22% as of September 30, 2024 and December 31, 2023, respectively. During October 2024, the Company repaid $69.1 million of the $360.6 million outstanding under the Revolving Facility.

During the second quarter of 2024, the Company repaid $25.0 million of the $50.0 million previously outstanding under the Term Facility. During October 2024, the Company repaid the remaining $25.0 million outstanding under the Term Facility.

At September 30, 2024, the Company was in compliance with the covenants contained in the credit agreement associated with the Revolving Facility as well as other long-term debt agreements.

Issuance of 4.950% Senior Notes due 2029

On August 21, 2024, the Company completed an underwritten public offering of $500.0 million in aggregate principal amount of its 4.950% Senior Notes. The 4.950% Senior Notes bear interest at a rate of 4.950% per annum, which is payable semi-annually in arrears during the first and third quarters of the year, beginning in the first quarter of 2025. The 4.950% Senior Notes will mature on September 1, 2029. The 4.950% Senior Notes are senior, unsecured obligations of the Company and (i) rank equal in right of payment to all of the Company’s existing and future senior unsecured indebtedness, (ii) rank senior in right of payment to all of the Company’s existing and future subordinated indebtedness, and (iii) rank effectively subordinated in right of payment to the Company’s future secured indebtedness. The net proceeds from the 4.950% Senior Notes offering were approximately $495.0 million, after deducting the underwriting discount and offering expenses paid and payable by the Company. The Company used the net proceeds from the offering, together with the Revolving Facility borrowings discussed above and cash on hand, to fund the Mott acquisition and pay related fees and expenses.
The Company may redeem all or a portion of the 4.950% Senior Notes at any time prior to maturity at the redemption prices set forth in the Supplemental Indenture governing the 4.950% Senior Notes (the “Indenture”). The terms of the 4.950% Senior Notes also require the Company to make an offer to repurchase all or a portion of the 4.950% Senior Notes (unless otherwise redeemed) upon a “Change of Control Triggering Event” (as defined in the Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. The 4.950% Senior Notes are not subject to any financial covenants under the Indenture; however, they are subject to cross-acceleration provisions.

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 September 30, 2024 and December 31, 2023:

(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 nine months ended September 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.

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:

As of September 30, 2024, there was $11.0 million of total unrecognized compensation cost related to stock options that is expected to be recognized over a weighted-average period of 1.4 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 September 30, 2024 and changes during the nine months ended September 30, 2024 are presented in the following table:

As of September 30, 2024, there was $18.0 million of total unrecognized compensation cost related to restricted stock that is expected to be recognized over a weighted-average period of 1.2 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 September 30, 2024 and December 31, 2023, the Company had accrued $3.7 million and $4.2 million, respectively, for cash-settled restricted stock in Accrued expenses in the Condensed Consolidated Balance Sheets and had accrued $2.5 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 September 30, 2024 and changes during the nine months ended September 30, 2024 are presented in the following table:

The Company’s provision for income taxes is based upon estimated annual tax rates for the year applied to federal income as well as state and foreign income in various jurisdictions, permanent differences between book and tax items, tax credits and the Company’s change in relative income in each jurisdiction. The provision for income taxes and the effective tax rates for the periods presented were as follows:

The three months ended September 30, 2024 had no material discrete tax items impacting the effective tax rate. The nine months ended September 30, 2024 benefited from the finalization of prior years’ research and development tax incentives with taxing authorities in a foreign jurisdiction and the finalization of tax impacts of a previously recorded legal entity restructuring. Both the three and nine months ended September 30, 2023 benefited from the finalization of the impact of research expenditure capitalization on the foreign derived intangible income deduction and the reduction of Global Intangible Low-Tax Income as a result of the tax amortization of goodwill related to the acquisition of Muon B.V. and its subsidiaries.

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. Adoption of the standard is not expected to have a material impact on the Company’s Consolidated Financial Statements, but will require additional segment expense disclosures when adopted in the Company’s Form 10-K for the year ending December 31, 2024 and in periodic reports thereafter.

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 Company’s financial statement disclosures.
