1. Basis of Presentation

Background - Knowles Corporation (NYSE:KN) is a market leader and global provider of high performance capacitors and radio frequency ("RF") products, balanced armature speakers, advanced micro-acoustic microphones, and audio solutions, serving the medtech, defense, electric vehicle, industrial, communications, and consumer electronics markets. The Company uses its leading position in SiSonicTM micro-electro-mechanical systems ("MEMS") microphones and strong capabilities in audio processing technologies to optimize audio systems and improve the user experience across consumer applications. Knowles is also a leader in hearing health acoustics, high performance capacitors, and RF solutions for a diverse set of markets. The Company's focus on the customer, combined with its unique technology, proprietary manufacturing techniques, and global operational expertise, enable the Company to deliver innovative solutions across multiple applications. References to "Knowles," "the Company," "we," "our," and "us" refer to Knowles Corporation and its consolidated subsidiaries.

Financial Statement Presentation - The accompanying unaudited interim Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP” or “U.S. GAAP”) for complete financial statements. These unaudited interim Consolidated Financial Statements should therefore be read in conjunction with the Consolidated Financial Statements and Notes thereto for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K.

The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect amounts reported in the Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates. Management uses historical experience and all available information to make these estimates. The unaudited interim Consolidated Financial Statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair statement of results for these interim periods.

As discussed in Note 3. Discontinued Operations, the Company reclassified the results of the Consumer MEMS Microphones ("CMM") segment to discontinued operations in the third quarter of 2024 based on its intention to divest this business. The results of operations and the related assets and liabilities for CMM have been classified as discontinued operations for all periods presented.

Share Repurchase Program - On February 24, 2020, the Company announced that its Board of Directors had authorized a share repurchase program of up to $100.0 million of the Company's common stock. On April 28, 2022, the Company announced that its Board of Directors had increased the authorization by up to $150.0 million in additional aggregate value. The timing and amount of any shares repurchased will be determined by the Company based on its evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. The Company is not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of the Company’s common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock. During the nine months ended September 30, 2024 and 2023, the Company repurchased 1,686,253 and 1,630,161 shares of common stock, respectively for a total of $29.5 million and $27.5 million, respectively.

Non-cash Operating Activities - Operating lease liabilities arising from obtaining right-of-use assets for the nine months ended September 30, 2024 and 2023 were $0.6 million and $2.5 million, respectively. These amounts reflect both continuing and discontinued operations.

Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at September 30, 2024 and 2023 were $1.0 million and $1.6 million, respectively. These amounts reflect both continuing and discontinued operations. These non-cash amounts are not reflected as "Capital expenditures" within Investing Activities on the Consolidated Statements of Cash Flows for the respective periods.

2. Recent Accounting Standards

In November 2023, the FASB issued ASU 2023-07 to expand reportable segment disclosure requirements. This guidance requires that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss. All annual disclosures about a reportable segment’s profit or loss and assets currently required by ASC 280 must also be disclosed in interim periods. Additionally, this standard requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This standard is effective for the Company beginning with its annual reporting for the year ended December 31, 2024 and its interim reporting for the three months ended March 31, 2025. Early adoption is permitted. The standard requires adoption on a retrospective basis for all prior periods presented in the financial statements. The Company does not expect the adoption of this standard to have a significant impact upon the financial statements.

In December 2023, the FASB issued ASU 2023-09 to enhance the transparency of income tax disclosures. This guidance requires that public business entities disclose, on an annual basis, specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. A public business entity is required to provide an explanation, if not otherwise evident, of the individual reconciling items disclosed, such as the nature, effect, and underlying causes and the judgment used in categorizing the reconciling items. This guidance also requires that all entities disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by those individual jurisdictions equal to or greater than 5 percent of the total. This standard is effective for the Company for its annual reporting for the year ended December 31, 2025. Early adoption is permitted. The standard requires adoption on a prospective basis, although retrospective adoption is permitted. The Company does not expect the adoption of this standard to have a significant impact upon the financial statements.

3. Discontinued Operations

Management and the Board of Directors periodically conduct strategic reviews of the Company’s businesses. On September 18, 2024, the Company entered into a Purchase and Sale Agreement with Syntiant Corp. (the "Purchase Agreement") to sell and assign certain assets and liabilities of the Company’s CMM segment for approximately $150.0 million in total consideration, consisting of $70.0 million in cash, subject to customary working capital and inventory adjustments, and $80.0 million in series D-2 preferred stock of Syntiant, to be issued upon the closing of this transaction. The Company will also share in certain separation costs pursuant to a credit for up to $13.5 million, which the buyer may apply to specified separation costs post-closing. In addition, the Company has committed to provide, under certain circumstances, up to $15.0 million in financing in connection with Syntiant's obligation to have $40.0 million of cash on the balance sheet, which financing would be junior to Syntiant's debt financing.

This transaction, which is subject to customary closing conditions, is expected to occur in the fourth quarter of 2024. The Purchase Agreement contains customary termination rights, including that the parties may terminate the Purchase Agreement (i) by mutual agreement, (ii) if the transaction has not closed by December 31, 2024, subject to certain extensions, or (iii) if a governmental entity with competent jurisdiction has issued a final and non-appealable order permanently restraining, preventing, making illegal, enjoining or otherwise prohibiting the consummation of any of the transactions contemplated by the Purchase Agreement.

The pending disposition of CMM meets the held-for-sale criteria described in Accounting Standards Codification ("ASC") 205-20, Presentation of Financial Statements – Discontinued Operations. In accordance with this guidance, the Company has reclassified the results of operations and financial position of CMM to discontinued operations for all periods presented as this disposal represents a strategic shift that has a major effect on the Company’s results of operations.

During the three and nine months ended September 30, 2024, the Company recorded goodwill impairment charges of $13.1 million and $262.5 million, respectively, to write down the carrying value of CMM to its fair value. In addition, the Company recorded an impairment charge of $2.3 million during the three and nine months ended September 30, 2024 to write down the carrying value of the CMM business to its fair value less costs to sell. This impairment is reflected as “Loss on disposal of business” in the results of discontinued operations above.

During the nine months ended September 30, 2024, the Company sold certain technology related to the CMM segment to a third party for total proceeds of $7.2 million. After transaction costs of $1.8 million, the Company recognized a net gain on the sale of this asset of $5.4 million during the nine months ended September 30, 2024. This gain is reflected as “Gain on sale of asset, net” in the results of discontinued operations above.

During the nine months ended September 30, 2023, the Company entered into an agreement to sell certain of its machinery and equipment related to the CMM segment to a third party for total proceeds of $11.4 million, which were received in their entirety in the second quarter of 2023. In addition, the Company received $1.1 million in the second quarter of 2023, which was initially reserved for a third-party payment. The Company transferred control of a portion of these assets with a fair value of approximately $5.5 million and $11.2 million to the buyer during the three and nine months ended September 30, 2023, respectively, resulting in a gain on sale of approximately $5.3 million and $11.0 million. The remaining assets were transferred to the buyer in the first quarter of 2024 for an immaterial gain. During the nine months ended September 30, 2024, the Company recorded an additional gain on sale of these assets of approximately $1.1 million as a result of changing its estimate on the amount owed to the third party. The Company has now completed this sale transaction.

4. Acquisition

On November 1, 2023, the Company acquired (i) all the issued and outstanding shares of Kaplan Electronics, Inc. and (ii) certain assets of Cornell Dubilier Electronics, Inc. and CD Aero, LLC (collectively, "Cornell Dubilier" or "CD") for aggregate consideration of $259.8 million, which equated to a total fair value of consideration transferred of $246.8 million. This purchase price of $246.8 million consisted of $136.9 million in cash payments and an interest-free seller note (the “Seller Note”) with a fair value of $109.9 million. The Seller Note consists of aggregate principal amounts of $122.9 million with $50.0 million maturing on November 1, 2024 and $72.9 million maturing on November 1, 2025 and is secured by certain assets (including equity interests) acquired in connection with the acquisition (see also Note 9. Borrowings).

CD is a manufacturer of film, electrolytic, and mica capacitors used in medtech, defense, and industrial electrification applications. The transaction was accounted for as a business combination under ASC 805. The Company has substantially completed the purchase price allocation for the acquisition of CD and has recorded certain measurement period adjustments to the purchase price allocation during the nine months ended September 30, 2024. As additional information is obtained about the net assets acquired within the measurement period (not to exceed one year from the date of acquisition), including finalization of asset appraisals, the Company will refine its estimates of the purchase price allocation.

Revolving Credit Facility

On February 8, 2023, the Company entered into an Amended and Restated Credit Agreement (the "A&R Credit Agreement") that amends and restates the prior Credit Agreement, dated September 4, 2020, and provides for a senior secured revolving credit facility with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million (the "Credit Facility"). The A&R Credit Agreement, among other things, extends the maturity date of the Credit Facility from January 2, 2024 to February 8, 2028, replaces the London Inter-Bank Offered Rate (“LIBOR”) with the Term Secured Overnight Financing Rate (“Term SOFR”) as a reference rate available for borrowings, amends the minimum Interest Coverage Ratio, and amends certain other financial covenants with which the Company must comply, as described below.

On September 25, 2023, the Company amended its A&R Credit Agreement to, among other things, (a) permit the Company in connection with the acquisition of CD, to incur senior priority seller financing indebtedness (the “Seller Note”) in an aggregate principal amount of $122.9 million secured by certain assets (including equity interests) acquired in connection with such acquisition and the capital stock of Cornell Dubilier, LLC (the “Acquisition Assets”), which shall mature two years after the effective date of such Seller Note (the “Seller Note Maturity Date”), (b) extends the requirement to pledge the Acquisition Assets that would otherwise constitute collateral under the Credit Agreement to the date that is 90 days after the Seller Note Maturity Date, and (c) restricts, until the Seller Note Maturity Date, the amount of dispositions and investments from the Company and certain of its subsidiaries into Cornell Dubilier, LLC and the acquired subsidiaries that constitute Acquisition Assets from exceeding $80.0 million in the aggregate. All other terms remain the same as the A&R Credit Agreement dated February 8, 2023.

On June 17, 2024, in anticipation of the CMM transaction, the Company entered into a Consent Memorandum with the administrative agent and lenders under the A&R Credit Agreement that would allow it to consummate the disposition without satisfying the 75% cash consideration condition contained in the A&R Credit Agreement so long as at least 30% of the consideration consists of cash.

Up to $100.0 million of the Credit Facility will be available in Euro, Pounds Sterling, and other currencies requested by the Company and up to $50.0 million of the Credit Facility will be made available in the form of letters of credit. Undrawn amounts under the Credit Facility accrue a commitment fee at a per annum rate of 0.225% to 0.350%, based on a leverage ratio grid.

At any time during the term of the Credit Facility, the Company may request an increase to the commitments under the Credit Facility to establish one or more incremental term loans or revolving credit facilities in an aggregate principal amount not to exceed the sum of $200.0 million, plus additional amounts, so long as the senior secured leverage ratio does not exceed 2.00 to 1.00.


Table of Contents			NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The A&R Credit Agreement includes requirements, to be tested quarterly, that the Company maintains (i) a minimum ratio of Consolidated EBITDA to consolidated cash interest expense of 3.00 to 1.00, (the "Interest Coverage Ratio"), (ii) a ratio of total indebtedness, minus netted cash in an aggregate amount not to exceed $50.0 million, to Consolidated EBITDA of 3.75 to 1.00 (the "Total Net Leverage Ratio"), and (iii) a maximum ratio of senior net secured indebtedness to Consolidated EBITDA of 3.25 to 1.00 (the "Senior Secured Net Leverage Ratio"). For these ratios, Consolidated EBITDA and consolidated interest expense are calculated using the most recent four consecutive fiscal quarters in a manner defined in the A&R Credit Agreement. At September 30, 2024, the Company was in compliance with these covenants and it expects to remain in compliance with all of its debt covenants over the next twelve months.

The interest rates under the Credit Facility will be, at the Borrowers' option (1) (A) in the case of borrowings denominated in U.S. dollars Term SOFR, (B) in the case of borrowings denominated in Sterling, Daily Simple Sonia, or (C) for borrowings denominated in Euro, EURIBOR, in each case, plus the rates per annum determined from time to time based on the total net leverage ratio of the Company as of the end of and for the most recent period of four fiscal quarters for which financial statements have been delivered (the "Applicable Margin"); or (2) in the case of borrowings denominated in U.S. dollars, alternate base rate ("ABR") (as defined in the A&R Credit Agreement) plus the Applicable Margin. The Applicable Margin for Term SOFR, Daily Simple Sonia, or EURIBOR could range from 1.50% to 2.50% while the Applicable Margin for ABR could range from 0.50% to 1.50%.

The weighted-average interest rate on the Company's borrowings under the Credit Facility and the 2020 credit facility was 7.24% and 6.43% for the nine months ended September 30, 2024 and 2023, respectively. The weighted-average commitment fee on the revolving line of credit was 0.26% and 0.23% for the nine months ended September 30, 2024 and 2023, respectively.

Seller Note

On November 1, 2023, the Company completed the acquisition of CD for a total purchase price of $246.8 million. This acquisition was funded by borrowings on the Revolving Credit Facility and an interest-free note from the seller with aggregate principal payments of $122.9 million (the "Seller Note"). The Seller Note is due and payable in cash with $50.0 million maturing on November 1, 2024 and $72.9 million maturing on November 1, 2025. On the acquisition date, the Company recorded the Seller Note at its present value of $109.9 million by discounting the future principal payments using an imputed rate of interest of approximately 7.1% in accordance with accounting guidance in ASC 835, Interest. During the three months ended September 30, 2024, the Company made an indemnity claim against the Seller Note of $0.2 million. The Company recognized imputed interest expense on the Seller Note of approximately $2.0 million and $6.0 million for the three and nine months ended September 30, 2024, respectively.

The Seller Note is secured by certain assets (including equity interest) acquired in connection with the acquisition. The Seller Note includes Knowles Capital Holdings, Inc. and Knowles Intermediate PD Holdings, LLC as borrowers, which jointly and severally agree to pay James P. Kaplan, as representative of the sellers of Cornell Dubilier, the principal amount of $122.9 million as described above. The Seller Note is not interest-bearing except at such time as an event of default has occurred, upon which and during the continuance of an event of default, all overdue principal will accrue interest at 2.0% per annum plus the SOFR-based rate otherwise applicable under the Company’s existing credit facility. The Seller Note is subject to customary conditions and events of default and the secured nature of the Seller Note is supported by a Security Agreement.

11. Income Taxes

Income taxes for the interim periods presented have been included in the accompanying Consolidated Financial Statements on the basis of an estimated annual effective tax rate ("ETR"). The determination of the consolidated provision for income taxes requires management to make certain judgments and estimates. Changes in the estimated level of annual pre-tax earnings or loss, tax laws, and changes resulting from tax audits can affect the overall ETR, which impacts the level of income tax expense or benefit and net income or loss. Judgments and estimates related to the Company’s projections and assumptions are inherently uncertain and therefore, actual results could differ materially from projections.

The Company's ETR from continuing operations for the three and nine months ended September 30, 2024 was 24.6% (inclusive of discrete items totaling $0.7 million of tax benefit) and 38.1% (inclusive of discrete items totaling $0.3 million of tax benefit), respectively. The discrete items impacting the tax provision for the three and nine months ended September 30, 2024 were primarily attributable to stock-based compensation and the deferred tax impact of a tax rate change. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2024 was 30.3% and 39.5%, respectively. The Company's ETR from continuing operations for the three and nine months ended September 30, 2023 was (34.5)% (inclusive of discrete items totaling $0.3 million of benefit) and (32.7)% (inclusive of discrete items totaling $0.3 million of expense), respectively. The discrete items impacting the tax provision for the three and nine months ended September 30, 2023 were primarily attributable to stock-based compensation and the recognition of foreign tax credits resulting from the release of IRS Notice 2023-55. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2023 was (31.9)% and (33.7)%, respectively.

The Company accrues taxes in various countries where it generates income and applies a valuation allowance in other jurisdictions, which resulted in the provisions and benefits for the three and nine months ended September 30, 2024 and 2023.

PSUs

The Company grants performance share units (“PSUs”) to senior management. In each case, the awards will cliff vest three years following the grant date. PSUs will be settled in shares of the Company's common stock. Depending on the Company's overall performance relative to the applicable measures, the size of the PSU awards are subject to adjustment, up or down, resulting in awards at the end of the performance period that can range from 0% to 225% of target. The Company will ratably recognize the expense over the applicable service period for each grant of PSUs and adjust the expense for the expected achievement of performance conditions as appropriate. The fair value of PSUs is determined by using a Monte Carlo simulation. For the awards granted in February 2024, 2023, and 2022, the number of PSUs that may be earned and vest is based on total shareholder return (“TSR”) relative to the component companies of the Russell 2000 Index over a three-year performance period.

The following table summarizes the Company's PSU activity for the nine months ended September 30, 2024:


	Share units	Weighted-average grant date fair value
Unvested at December 31, 2023	864,749	$	29.28

For the three and nine months ended September 30, 2023, the weighted-average number of anti-dilutive potential common shares for stock-based awards excluded from the diluted earnings per share calculation above was 1.7 million and 2.4 million, respectively.

14. Commitments and Contingent Liabilities

From time to time, the Company is involved in various legal proceedings and claims arising in the ordinary course of its business. The majority of these claims and proceedings relate to commercial, warranty, employment, and intellectual property matters. Although the ultimate outcome of any legal proceeding or claim cannot be predicted with certainty, based on present information, including management’s assessment of the merits of the particular claim, the Company believes that the disposition of these legal proceedings or claims, individually or in the aggregate, after taking into account recorded accruals and the availability and limits of insurance coverage, will not have a material adverse effect on its cash flow, results of operations, or financial condition.

The Company owns many patents and other intellectual property pertaining to its products, technology, and manufacturing processes. Some of the Company's patents have been and may continue to be infringed upon or challenged by others. In appropriate cases, the Company has taken and will take steps to protect and defend its patents and other intellectual property, including through the use of legal proceedings in various jurisdictions around the world. Such steps have resulted in and may continue to result in retaliatory legal proceedings, including litigation or other legal proceedings in various jurisdictions and forums around the world alleging infringement by the Company of patents owned by others. The costs of investigations and legal proceedings relating to the enforcement and defense of the Company’s intellectual property may be substantial. Additionally, in multi-forum disputes, the Company may incur adverse judgments with regard to certain claims in certain jurisdictions and forums while still contesting other related claims against the same opposing party in other jurisdictions and forums.

Intellectual Property Infringement Claims

The Company may, on a limited basis, provide contractual indemnities for certain losses that arise out of claims that its products infringe on the intellectual property of others. It is not possible to determine the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Historically, the Company has not made significant payments under such indemnity arrangements. The Company’s legal accruals associated with these indemnity arrangements were not significant at September 30, 2024 and December 31, 2023.

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 our Consolidated Financial Statements and related Notes included elsewhere in this Quarterly Report on Form 10-Q.

Overview

We are a market leader and global provider of high performance electronics for demanding applications, including ceramic capacitors and radio frequency ("RF") filters, advanced medtech microphones, balanced armature speakers, advanced micro-acoustic microphones, and audio solutions, serving the medtech, defense, electric vehicle, industrial, communications, and consumer electronics markets. Our focus on the customer, combined with unique technology, proprietary manufacturing techniques, and global operational expertise, enables us to deliver innovative solutions across multiple applications. References to "Knowles," the "Company," "we," "our," or "us" refer to Knowles Corporation and its consolidated subsidiaries, unless the context otherwise requires.

We sell our products directly to original equipment manufacturers ("OEMs") and to their contract manufacturers and suppliers and through distributors worldwide.

Recent Developments

On September 18, 2024, we entered into a definitive agreement to sell and assign certain assets and liabilities of the Company’s Consumer MEMS Microphones (“CMM”) business to Syntiant Corp. ("Syntiant") for approximately $150.0 million in total consideration, consisting of $70.0 million in cash, subject to customary working capital and inventory adjustments, and $80.0 million in Syntiant Series D-2 preferred stock, to be issued upon the closing of this transaction. The Company will also share in certain separation costs pursuant to a credit for up to $13.5 million, which Syntiant may apply to specified separation costs post-closing. In addition, the Company has committed to provide, under certain circumstances, up to $15.0 million in financing in connection with Syntiant's obligation to have $40.0 million of cash on the balance sheet, which financing would be junior to Syntiant's debt financing. The consummation of the transaction is not subject to a financing condition, but is subject to customary closing conditions. The transaction is expected to close in the fourth quarter of 2024. For additional information, refer to Note 3. Discontinued Operations to our Consolidated Financial Statements under Part I, Item 1, "Financial Statements."

The CMM divestiture represents a strategic shift that will have a major effect on our operations and financial results. As a result, we have reclassified the results of operations and financial position of CMM to discontinued operations for all periods presented. Unless otherwise noted, discussion within this Quarterly Report to the consolidated financial statements relates to our continuing operations.

This divestiture supports Knowles' continued transformation into an industrial technology company, consisting of its Precision Devices ("PD") and MedTech & Specialty Audio ("MSA") segments, primarily serving the defense, medtech, industrial, and electrification markets. We may incur some amount of dis-synergies following the sale of the CMM business due to the reduced size of our company and, as a result, we may undertake actions to help ensure that our cost structure is appropriate to support our remaining businesses.

Non-GAAP Financial Measures

In addition to the GAAP financial measures included in this item, we have presented certain non-GAAP financial measures. We use non-GAAP measures as supplements to our GAAP results of operations in evaluating certain aspects of our business, and our executive management team and Board of Directors focus on non-GAAP items as key measures of our performance for business planning purposes. These measures assist us in comparing our performance between various reporting periods on a consistent basis, as these measures remove from operating results the impact of items that, in our opinion, do not reflect our core operating performance. We believe that our presentation of non-GAAP financial measures is useful because it provides investors and securities analysts with the same information that we use internally for purposes of assessing our core operating performance. The Company does not consider these non-GAAP financial measures to be a substitute for the information provided by GAAP financial results. For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures, see the reconciliation included herein.

Revenues

Revenues for the third quarter of 2024 were $142.5 million, compared with $108.1 million for the third quarter of 2023, an increase of $34.4 million or 31.8%. PD revenues increased $28.6 million due to our acquisition of the CD business. However, our legacy PD business experienced lower demand from the industrial and communication markets as a result of continued demand weakness associated with excess customer and channel inventory, partially offset by higher demand from the defense and medtech markets. MSA revenues increased $5.8 million, primarily due to higher shipping volumes of hearing health products driven by stronger end market demand and higher shipping volumes into the specialty audio market, partially offset by lower average pricing on mature products.

Cost of Goods Sold

Cost of goods sold ("COGS") for the third quarter of 2024 was $79.5 million, compared with $57.5 million for the third quarter of 2023, an increase of $22.0 million or 38.3%. This increase was primarily due to our acquisition of CD and lower factory capacity utilization in our legacy PD business, partially offset by product cost reductions and factory productivity improvements in the legacy PD business.

Restructuring Charges

During the third quarter of 2024, we recorded restructuring charges of $0.1 million within Gross profit for costs associated with transferring certain capacitors manufacturing to existing facilities to further optimize operations, and $0.1 million within Operating expenses related to headcount reductions within the PD segment. For additional information, refer to Note 8. Restructuring and Related Activities to our Consolidated Financial Statements.

During the third quarter of 2023, we recorded restructuring charges of $1.3 million for severance pay and benefits related to headcount reductions within our PD segment and $0.4 million in other charges, primarily in Operating expenses. For additional information, refer to Note 8. Restructuring and Related Activities to our Consolidated Financial Statements.

Gross Profit and Non-GAAP Gross Profit

Gross profit for the third quarter of 2024 was $62.9 million, compared with $50.4 million for the third quarter of 2023, an increase of $12.5 million or 24.8%. Gross profit margin (gross profit as a percentage of revenues) for the third quarter of 2024 was 44.1%, compared with 46.6% for the third quarter of 2023. The increase in gross profit was primarily due to our acquisition of CD. The decrease in gross profit margin was primarily due to the impacts of the acquisition of CD. Excluding the impacts of CD, gross profit margins increased primarily due to product cost reductions and factory productivity improvements in our legacy PD business, partially offset by lower factory capacity utilization in our legacy PD business and lower average pricing on mature products in our MSA business.

Non-GAAP gross profit for the third quarter of 2024 was $64.8 million, compared with $50.9 million for the third quarter of 2023, an increase of $13.9 million or 27.3%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the third quarter of 2024 was 45.5%, compared with 47.1% for the third quarter of 2023. The increase in non-GAAP gross profit was primarily due to our acquisition of CD. The decrease in non-GAAP gross profit margin was primarily due to the impacts of the acquisition of CD. Excluding the impacts of CD, non-GAAP gross profit margins increased primarily due to product cost reductions and factory productivity improvements in our legacy PD business, partially offset by lower factory capacity utilization in our legacy PD business and lower average pricing on mature products in our MSA business.

Research and Development Expenses

Research and development expenses for the third quarter of 2024 were $10.2 million, compared with $8.1 million for the third quarter of 2023, an increase of $2.1 million or 25.9%. Research and development expenses as a percentage of revenues for the third quarter of 2024 and 2023 were 7.2% and 7.5%, respectively. The increase in expenses was primarily driven by our acquisition of the CD business that increased expenses in our PD segment. The decrease in expenses as a percentage of revenues was driven by our acquisition of the CD business.

Selling and Administrative Expenses

Selling and administrative expenses for the third quarter of 2024 were $33.9 million, compared with $29.4 million for the third quarter of 2023, an increase of $4.5 million or 15.3%. Selling and administrative expenses as a percentage of revenues for the third quarter of 2024 and 2023 were 23.8% and 27.2%, respectively. The increase in expenses was primarily driven by our acquisition of CD, partially offset by lower professional fees and the benefits of PD restructuring actions taken in the prior year. The decrease in expenses as a percentage of revenues was driven by higher revenues.

Interest Expense, net

Interest expense for the third quarter of 2024 was $3.9 million, compared with $0.6 million for the third quarter of 2023, an increase of $3.3 million. The increase is primarily due to imputed interest expense on our Seller Note from the CD acquisition and a higher outstanding revolving credit facility balance during the third quarter of 2024. For additional information on borrowings and interest expense, refer to Note 9. Borrowings to our Consolidated Financial Statements.

Other Expense (Income), net

Other expense for the third quarter of 2024 was $2.6 million, compared with income of $0.5 million for the third quarter of 2023, a change of $3.1 million.

Provision for (Benefit from) Income Taxes and Non-GAAP Provision for Income Taxes

The effective tax rate ("ETR") from continuing operations for the third quarter of 2024 and 2023 was 24.6% and (34.5)%, respectively. The ETR from continuing operations for the third quarter of 2024 includes discrete items totaling $0.7 million of tax benefit primarily attributable to stock-based compensation and the deferred tax impact of a tax rate change. The ETR from continuing operations for the third quarter of 2023 includes discrete items totaling $0.3 million of tax benefit primarily attributable to stock-based compensation and the recognition of foreign tax credits resulting from the release of IRS Notice 2023-55. Absent the discrete items, the ETR from continuing operations for the third quarter of 2024 and 2023 was 30.3% and (31.9)%, respectively. The Company accrues taxes in various countries where it generates income and applies a valuation allowance in other jurisdictions, which resulted in the provision and benefit for the third quarter of 2024 and 2023, respectively. The change in the ETR was mainly due to the impact of intangible property transfers in 2023, the mix of earnings and losses by taxing jurisdictions, and net discrete items.

The non-GAAP ETR from continuing operations for the third quarter of 2024 and 2023 was 7.3% and 21.7%, respectively. The non-GAAP ETR from continuing operations includes discrete items totaling $0.9 million of tax benefit and no discrete impact for the three months ended September 30, 2024 and 2023, respectively. Absent the discrete items, the non-GAAP ETR from continuing operations for the third quarter of 2024 and 2023 was 10.7% and 21.7%, respectively. The change in the non-GAAP ETR was primarily due to increased utilization of foreign tax credits compared to the prior year.

Earnings from Continuing Operations

Earnings from continuing operations for the third quarter of 2024 was $9.2 million, compared with $15.2 million for the third quarter of 2023, a decrease of $6.0 million. As described above, the decrease is primarily due to income tax expense in the third quarter of 2024 compared to a benefit for the third quarter of 2023, along with higher operating expenses, interest expense, and unfavorable foreign currency changes, partially offset by higher gross profit.

Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

Earnings from continuing operations before interest and income taxes ("EBIT") for the third quarter of 2024 was $16.1 million, compared with $11.9 million for the third quarter of 2023, an increase of $4.2 million. EBIT margin (EBIT as a percentage of revenues) for the third quarter of 2024 was 11.3%, compared with 11.0% for the third quarter of 2023. The increase in EBIT was primarily due to higher gross profit, partially offset by higher operating expenses and unfavorable foreign currency changes. The increase in EBIT margin was primarily due to higher gross profit, partially offset by higher operating expenses, the impacts of the acquisition of CD on gross margins, and unfavorable foreign currency changes.

Adjusted earnings before interest and income taxes ("Adjusted EBIT") from continuing operations for the third quarter of 2024 was $30.0 million, compared with $24.6 million for the third quarter of 2023, an increase of $5.4 million. Adjusted EBIT margin (Adjusted EBIT from continuing operations as a percentage of revenues) for the third quarter of 2024 was 21.1%, compared with 22.8% for the third quarter of 2023. The increase in Adjusted EBIT was primarily due to higher non-GAAP gross profit, partially offset by higher non-GAAP operating expenses, and unfavorable foreign currency changes. The decrease in Adjusted EBIT margin was primarily due to higher non-GAAP operating expenses, the impacts of the acquisition of CD on gross margins, and unfavorable foreign currency changes, partially offset by higher gross profit.

(Loss) Earnings from Discontinued Operations, net

Loss from discontinued operations for the third quarter of 2024 was $8.7 million, compared with earnings of $1.4 million for the third quarter of 2023, a decrease of $10.1 million. The change in discontinued operations was primarily driven by our goodwill impairment and loss on disposal of business related to the pending divestiture of CMM, partially offset by favorable income tax changes. For additional information, refer to Note 3. Discontinued Operations to our Consolidated Financial Statements.

Diluted Earnings per Share from Continuing Operations and Non-GAAP Diluted Earnings per Share from Continuing Operations

Diluted earnings per share from continuing operations was $0.10 for the third quarter of 2024, compared with $0.17 for the third quarter of 2023, a decrease of $0.07. As described above, the decrease is primarily due to income tax expense in the third quarter of 2024 compared to a benefit for the third quarter of 2023, along with higher operating expenses, interest expense, and unfavorable foreign currency changes, partially offset by higher gross profit.

Non-GAAP diluted earnings per share from continuing operations was $0.26 for the third quarter of 2024, compared with $0.20 for the third quarter of 2023, an increase of $0.06. As described above, the increase was due to higher non-GAAP gross profit and lower non-GAAP income tax expense, partially offset by higher non-GAAP operating expenses, interest expense, and unfavorable foreign currency changes.

Revenues

Revenues for the nine months ended September 30, 2024 were $411.0 million, compared with $317.6 million for the nine months ended September 30, 2023, an increase of $93.4 million or 29.4%. PD revenues increased $75.5 million due to our acquisition of the CD business, partially offset by lower demand from the industrial and communication markets in our legacy PD business as a result of continued demand weakness associated with excess customer and channel inventory. MSA revenues increased $17.9 million, primarily due to higher shipping volumes of hearing health products driven by stronger end market demand, partially offset by lower shipping volumes into the specialty audio market and lower average pricing on mature products. In addition, revenues in the nine months ended September 30, 2023 were unfavorably impacted by financial incentives offered to customers in the fourth quarter of 2022, which resulted in higher shipping volumes in the fourth quarter of 2022 and lower revenues in the first quarter of 2023.

Cost of Goods Sold

COGS for the nine months ended September 30, 2024 was $235.7 million, compared with $172.2 million for the nine months ended September 30, 2023, an increase of $63.5 million or 36.9%. This increase was primarily due to our acquisition of CD, lower factory capacity utilization in our legacy PD business, partially offset by product cost reductions and favorable MSA product mix.

(1) In addition to the GAAP financial measures included herein, Knowles has presented certain non-GAAP financial measures that exclude certain amounts that are included in the most directly comparable GAAP measures. Knowles believes that non-GAAP measures are useful as supplements to its GAAP results of operations to evaluate certain aspects of its operations and financial performance, and its management team primarily focuses on non-GAAP items in evaluating Knowles' performance for business planning purposes. Knowles also believes that these measures assist it with comparing its performance between various reporting periods on a consistent basis, as these measures remove from operating results the impact of items that, in Knowles' opinion, do not reflect its core operating performance. Knowles believes that its presentation of non-GAAP financial measures is useful because it provides investors and securities analysts with the same information that Knowles uses internally for purposes of assessing its core operating performance.

(2) Production transfer costs represent duplicate costs incurred to migrate manufacturing to facilities primarily within the United States. These amounts are included in the corresponding Gross profit and Earnings from continuing operations before interest and income taxes for each period presented.

(2) These expenses are related to the acquisition of CD. These expenses include ongoing costs to facilitate integration and the amortization of fair value adjustments to inventory.

Revenues

PD revenues were $227.2 million for the nine months ended September 30, 2024, compared with $151.7 million for the nine months ended September 30, 2023, an increase of $75.5 million or 49.8%. Revenues increased due to our acquisition of the CD business, partially offset by lower demand from the industrial and communication markets in our legacy PD business as a result of continued demand weakness associated with excess customer and channel inventory.

Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

PD EBIT was $10.5 million for the nine months ended September 30, 2024, compared with $21.6 million for the nine months ended September 30, 2023, a decrease of $11.1 million. EBIT margin for the nine months ended September 30, 2024 was 4.6%, compared to 14.2% for the nine months ended September 30, 2023. The decreases were primarily due to increased operating expenses, partially offset by higher gross profit. The increase in operating expenses was primarily driven by the acquisition of the CD business, which includes higher intangible amortization expenses of $8.5 million. The gross profit increase was primarily driven by our acquisition of CD, partially offset by lower gross profit margins. The lower gross profit margins were impacted by lower factory capacity utilization in our legacy PD business, the acquisition of CD, production transfer costs, and the amortization of fair value adjustments to inventory for the CD acquisition, partially offset by product cost reductions and factory productivity improvements in our legacy PD business.

PD Adjusted EBIT was $37.7 million for the nine months ended September 30, 2024, compared with $30.0 million for the nine months ended September 30, 2023, an increase of $7.7 million. Adjusted EBIT margin for the nine months ended September 30, 2024 was 16.6%, compared with 19.8% for the nine months ended September 30, 2023. The increase in Adjusted EBIT was primarily due to higher non-GAAP gross profit, partially offset by higher non-GAAP operating expenses and lower non-GAAP gross profit margins. The decrease in adjusted EBIT margin was primarily due to higher non-GAAP operating expenses and lower non-GAAP gross profit margins. The increase in operating expenses was primarily driven by the acquisition of the CD business. The lower non-GAAP gross profit margins were impacted by the acquisition of CD and lower factory capacity utilization in our legacy PD business, partially offset by product cost reductions and factory productivity improvements in our legacy PD business.

Revenues

MSA revenues were $183.8 million for the nine months ended September 30, 2024, compared with $165.9 million for the nine months ended September 30, 2023, an increase of $17.9 million or 10.8%. Revenues increased primarily due to higher shipping volumes of hearing health products driven by stronger end market demand, partially offset by lower shipping volumes into the specialty audio market and lower average pricing on mature products. In addition, revenues in the nine months ended September 30, 2023 were unfavorably impacted by financial incentives offered to customers in the fourth quarter of 2022, which resulted in higher shipping volumes in the fourth quarter of 2022 and lower revenues in the first quarter of 2023.

Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

MSA EBIT was $71.9 million for the nine months ended September 30, 2024, compared with $57.4 million for the nine months ended September 30, 2023, an increase of $14.5 million or 25.3%. EBIT margin for the nine months ended September 30, 2024 was 39.1%, compared with 34.6% for the nine months ended September 30, 2023. The increases were primarily due to due to improved operating leverage, including the impacts of higher gross profit margins driven by favorable product mix, foreign currency changes, and product cost reductions, partially offset by lower average pricing on mature products.

MSA Adjusted EBIT was $75.0 million for the nine months ended September 30, 2024, compared with $60.0 million for the nine months ended September 30, 2023, an increase of $15.0 million.

Liquidity and Capital Resources

Historically, we have generated and expect to continue to generate positive cash flow from operations. Our ability to fund our operations and capital needs will depend on our ongoing ability to generate cash from operations and access to capital markets. We believe that our future cash flow from operations and access to capital markets will provide adequate resources to fund our working capital needs, capital expenditures, strategic investments, and share repurchases. We have secured a revolving line of credit in the United States from a syndicate of commercial banks to provide additional liquidity. Furthermore, if we were to require additional cash above and beyond our cash on the balance sheet, the free cash flow generated by the business, and availability under our revolving credit facility, we would most likely seek to raise long-term financing through the U.S. debt or bank markets.

Due to the global nature of our operations, a portion of our cash is generated and typically held outside the United States. Our cash and cash equivalents totaled $92.6 million and $87.3 million at September 30, 2024 and December 31, 2023, respectively. Of these amounts, cash held by our non-U.S. operations totaled $32.7 million and $71.8 million as of September 30, 2024 and December 31, 2023, respectively. To the extent we repatriate these funds to the U.S., we may be required to pay U.S. state income taxes and applicable foreign withholding taxes on those amounts during the period when such repatriation occurs. Management will continue to reassess our need to repatriate the earnings of our foreign subsidiaries. We expect to reduce our cash balance in the second half of the year, primarily driven by the payment of the Seller Note related to the CD acquisition and debt reduction, partially offset by cash generated from operations.

On September 18, 2024, we entered into a definitive agreement to sell our CMM business for $150.0 million. For additional information, refer to Note 3. Discontinued Operations to our Consolidated Financial Statements. On June 17, 2024 in anticipation of the CMM transaction, we entered into a Consent Memorandum with the administrative agent and our lenders under the A&R Credit Agreement (as defined below) regarding consents to certain conditions applicable to disposition of assets. For additional information refer to Note 9. Borrowings.

On November 1, 2023, we acquired (i) all the issued and outstanding shares of Kaplan Electronics, Inc. and (ii) certain assets of Cornell Dubilier Electronics, Inc. and CD Aero, LLC (collectively, "Cornell Dubilier" or "CD") for aggregate consideration of $259.8 million, which equated to a total fair value of consideration transferred of $246.8 million. This acquisition's operations are included in the PD segment. For additional information, refer to Note 4. Acquisition to our Consolidated Financial Statements.

On September 25, 2023, the Company amended its Amended and Restated Credit Agreement (the "A&R Credit Agreement") to, among other things, (a) permit the Company in connection with the acquisition of Cornell Dubilier, to incur senior priority seller financing indebtedness (the “Seller Note”) in an aggregate principal amount of $122.9 million secured by certain assets (including equity interests) acquired in connection with such acquisition and the capital stock of Cornell Dubilier, LLC (the “Acquisition Assets”), which shall mature two years after the effective date of such Seller Note (the “Seller Note Maturity Date”), (b) extends the requirement to pledge the Acquisition Assets that would otherwise constitute collateral under the Credit Agreement to the date that is 90 days after the Seller Note Maturity Date, and (c) restricts, until the Seller Note Maturity Date, the amount of dispositions and investments from the Company and certain of its subsidiaries into Cornell Dubilier, LLC and the acquired subsidiaries that constitute Acquisition Assets from exceeding $80.0 million the aggregate. All other terms remain the same as the A&R Credit Agreement dated February 8, 2023.

On February 8, 2023, we entered into the A&R Credit Agreement that amends and restates the prior Credit Agreement (the "2020 Credit Agreement"), which provides for a senior secured revolving credit facility with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. As of September 30, 2024, outstanding borrowings under the Credit Facility were $108.0 million. At any time during the term of the Credit Facility, we will be permitted to request an increase to the commitments under the Credit Facility to establish one or more incremental term loans or revolving credit facilities in an aggregate principal amount not to exceed $200.0 million for all such incremental facilities. Commitments under the Credit Facility will terminate, and loans outstanding thereunder will mature, on February 8, 2028. For additional information, refer to Note 9. Borrowings to our Consolidated Financial Statements.

On February 24, 2020, we announced that our Board of Directors had authorized a share repurchase program of up to $100.0 million of our common stock. On April 28, 2022, we announced that our Board of Directors had increased the authorization by up to $150.0 million in additional aggregate value. At September 30, 2024, we have $68.2 million remaining that may yet be repurchased under our share repurchase program. The timing and amount of any shares repurchased will be determined by us based on our evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. We are not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of our common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock. During the nine months ended September 30, 2024 and 2023, the Company repurchased 1,686,253 and 1,630,161 shares of common stock, respectively, for a total of $29.5 million and of $27.5 million, respectively.

Cash flows from operating, investing, and financing activities as reflected in our Consolidated Statements of Cash Flows and are presented on a consolidated basis, including discontinued operations. Cash flows are summarized in the following table:


	Nine Months Ended September 30,
(in millions)	2024		2023
Net cash flows provided by (used in):
Operating activities	$	95.0	$	62.3
Investing activities	(3.1)		0.3
Financing activities	(87.2)		(35.3)
Effect of exchange rate changes on cash and cash equivalents	0.6		(0.4)
Net increase in cash and cash equivalents	$	5.3	$	26.9

Operating Activities

Cash provided by operating activities adjusts net earnings for certain non-cash items, including impairment charges, depreciation expense, amortization of intangible assets, stock-based compensation, changes in deferred income taxes, and the effects of changes in operating assets and liabilities. Excluding non-cash items, the increase in cash provided by operating activities in 2024 is primarily due to an increase in net earnings driven by higher revenues and gross profit. The increase was partially offset by higher restructuring and incentive compensation payments in 2024.

Investing Activities

The cash used in investing activities during 2024 was primarily driven by capital expenditures, which were lower in 2024 as compared to 2023, offset by proceeds from the sale of intellectual property. The cash provided by investing activities during 2023 was primarily driven by proceeds from the sale of certain machinery and equipment, partially offset by capital expenditures to support product innovation and cost savings.

In 2024, we expect capital expenditures to be in the range of 2.0% to 3.0% of revenues.

Table of Contents

Financing Activities

Cash used in financing activities during 2024 was primarily related to the $29.5 million of repurchases of common stock, the $52.0 million net payments on the revolving credit facility, the $6.4 million payment of taxes related to net share settlement of equity awards, and partially offset by proceeds of $2.1 million from the exercise of options. Cash used in financing activities during 2023 was primarily related to the $27.5 million of repurchases of common stock, the $6.2 million payment of taxes related to net share settlement of equity awards, and the $1.9 million payment of debt issuance costs, partially offset by proceeds of $1.6 million from the exercise of options.

Adjusted Free Cash Flow

In addition to measuring cash flow generation based on the operating, investing, and financing classifications included in the Consolidated Statement of Cash Flows (including discontinued operations), Knowles also measures adjusted free cash flow and adjusted free cash flow as a percentage of revenues. Adjusted free cash flow is defined as non-GAAP net cash attributable to continuing operations less non-GAAP capital expenditures attributable to continuing operations. Non-GAAP net cash attributable to continuing operations is defined as net cash provided by operating activities less amounts attributable to discontinued operations. Non-GAAP capital expenditures attributable to continuing operations is defined as capital expenditures less amounts attributable to discontinued operations. Knowles believes these measures are helpful in measuring its cash generated from its continuing operations that is available to repay debt, fund acquisitions, and repurchase Knowles common stock. Adjusted free cash flow and adjusted free cash flow as a percentage of revenues are not presented in accordance with GAAP and may not be comparable to similarly titled measures used by other companies in our industry. As such, adjusted free cash flow and adjusted free cash flow as a percentage of revenues should not be considered in isolation from, or as an alternative to, any other liquidity measures determined in accordance with GAAP.

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


	Nine Months Ended September 30,
	2024			2023
Net cash provided by operating activities	$	95.0		$	62.3
Less: amounts attributable to discontinued operations	(22.1)			(21.6)
Non-GAAP net cash attributable to continuing operations	72.9			40.7

Capital expenditures	(10.3)			(11.8)
Less: amounts attributable to discontinued operations	0.9			3.8
Non-GAAP capital expenditures attributable to continuing operations	(9.4)			(8.0)

Non-GAAP net cash attributable to continuing operations	72.9			40.7
Non-GAAP capital expenditures attributable to continuing operations	(9.4)			(8.0)
Adjusted free cash flow	$	63.5		$	32.7

Adjusted free cash flow as a % of revenues	15.5		%	10.3		%

Contingent Obligations

We are involved in various legal proceedings, claims, and investigations arising in the ordinary course of business. Legal contingencies are discussed in Note 14. Commitments and Contingent Liabilities to our Consolidated Financial Statements.

Critical Accounting Estimates

This discussion and analysis of results of operations and financial condition is based on our Consolidated Financial Statements, which have been prepared in conformity with U.S. GAAP. The preparation of these financial statements requires the use of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses, and related disclosures. In preparing these financial statements, we have made our best estimates and judgments of certain amounts included in the financial statements. Estimates are revised periodically. Actual results could differ from these estimates.

Table of Contents

The information concerning our critical accounting estimates can be found under Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the Securities and Exchange Commission on February 21, 2024. There are no material changes in our previously reported critical accounting estimates.

Recent Accounting Standards

The issuance of recent accounting standards, as included in Note 2. Recent Accounting Standards to our Consolidated Financial Statements, is not expected to have a significant impact on our revenue, earnings, or liquidity.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

During the nine months ended September 30, 2024, there were no material changes to the information on market risk exposure disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023. For a discussion of our exposure to market risk as of December 31, 2023, refer to Item 7A, Quantitative and Qualitative Disclosures about Market Risk, contained in our Annual Report on Form 10-K for the year ended December 31, 2023.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management has evaluated, under the supervision and with the participation of our chief executive officer ("CEO") and chief financial officer ("CFO"), the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the period covered by this report. Based on that evaluation, our CEO and CFO have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective in ensuring that information required to be disclosed in our Exchange Act reports is (1) recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (2) accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the third quarter of 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. The Company is in the process of reviewing the internal control structure of an acquired business and, if necessary, will make appropriate changes as we incorporate our controls and procedures into the recently acquired business.

Inherent Limitations on Effectiveness of Controls

Our management, including the CEO and CFO, do not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, will be detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by intentionally falsified documentation, by collusion of two or more individuals within Knowles or third parties, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

For a discussion of contingencies related to legal proceedings, see Note 14. Commitments and Contingent Liabilities to our Consolidated Financial Statements, which is incorporated herein by reference.

Except as otherwise noted above, there have been no material developments in legal proceedings.

Item 1A. Risk Factors

There have been no material changes from the risk factors previously disclosed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023, other than as set forth below.

If we are unsuccessful in implementing our divestment strategy for the CMM business our business and financial results may be adversely affected.

The planned strategic divestiture of our CMM business involves significant risks and uncertainties, some of which are beyond our control. The occurrence of an event, change, or other circumstance, such as various closing conditions associated with the transaction not being satisfied or waived, could give rise to the transaction terminating or a delay in consummation. Similarly, failure to obtain, delays in obtaining, or adverse conditions contained in, regulatory or other required approvals, could impact the timing and certainty of consummation. Further, we may encounter unanticipated difficulties or expenditures relating to the transaction, such as legal proceedings that may be instituted against the Company and others. The divestiture of CMM may also result in disruptions to our ongoing business due to, for example, challenges associated with the separation of business infrastructure, difficulties in employee retention, and the response of customers, distributors, suppliers and competitors.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Issuer Purchases of Equity Securities

On February 24, 2020, the Company announced that its Board of Directors had authorized a share repurchase program of up to $100.0 million of the Company's common stock. On April 28, 2022, the Company announced that its Board of Directors had increased the authorization by up to $150.0 million in additional aggregate value. The timing and amount of any shares repurchased will be determined by the Company based on its evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. The Company is not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of the Company’s common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock.

Below is a summary of share repurchases for the three months ended September 30, 2024:


(in millions, except share and per share amounts)
Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Program	Approximate Dollar Value of Shares That May Yet Be Purchased Under The Program

September 2024	253,264	$	17.77	253,264	$	68.2

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Basis of Presentation	1. Basis of Presentation Background - Knowles Corporation (NYSE:KN) is a market leader and global provider of high performance capacitors and radio frequency ("RF") products, balanced armature speakers, advanced micro-acoustic microphones, and audio solutions, serving the medtech, defense, electric vehicle, industrial, communications, and consumer electronics markets. The Company uses its leading position in SiSonicTM micro-electro-mechanical systems ("MEMS") microphones and strong capabilities in audio processing technologies to optimize audio systems and improve the user experience across consumer applications. Knowles is also a leader in hearing health acoustics, high performance capacitors, and RF solutions for a diverse set of markets. The Company's focus on the customer, combined with its unique technology, proprietary manufacturing techniques, and global operational expertise, enable the Company to deliver innovative solutions across multiple applications. References to "Knowles," "the Company," "we," "our," and "us" refer to Knowles Corporation and its consolidated subsidiaries. Financial Statement Presentation - The accompanying unaudited interim Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP” or “U.S. GAAP”) for complete financial statements. These unaudited interim Consolidated Financial Statements should therefore be read in conjunction with the Consolidated Financial Statements and Notes thereto for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K. The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect amounts reported in the Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates. Management uses historical experience and all available information to make these estimates. The unaudited interim Consolidated Financial Statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair statement of results for these interim periods. As discussed in Note 3. Discontinued Operations, the Company reclassified the results of the Consumer MEMS Microphones ("CMM") segment to discontinued operations in the third quarter of 2024 based on its intention to divest this business. The results of operations and the related assets and liabilities for CMM have been classified as discontinued operations for all periods presented. Share Repurchase Program - On February 24, 2020, the Company announced that its Board of Directors had authorized a share repurchase program of up to $100.0 million of the Company's common stock. On April 28, 2022, the Company announced that its Board of Directors had increased the authorization by up to $150.0 million in additional aggregate value. The timing and amount of any shares repurchased will be determined by the Company based on its evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. The Company is not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of the Company’s common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock. During the nine months ended September 30, 2024 and 2023, the Company repurchased 1,686,253 and 1,630,161 shares of common stock, respectively for a total of $29.5 million and $27.5 million, respectively. Non-cash Operating Activities - Operating lease liabilities arising from obtaining right-of-use assets for the nine months ended September 30, 2024 and 2023 were $0.6 million and $2.5 million, respectively. These amounts reflect both continuing and discontinued operations. Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at September 30, 2024 and 2023 were $1.0 million and $1.6 million, respectively. These amounts reflect both continuing and discontinued operations. These non-cash amounts are not reflected as "Capital expenditures" within Investing Activities on the Consolidated Statements of Cash Flows for the respective periods.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Standards	2. Recent Accounting Standards In November 2023, the FASB issued ASU 2023-07 to expand reportable segment disclosure requirements. This guidance requires that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss. All annual disclosures about a reportable segment’s profit or loss and assets currently required by ASC 280 must also be disclosed in interim periods. Additionally, this standard requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This standard is effective for the Company beginning with its annual reporting for the year ended December 31, 2024 and its interim reporting for the three months ended March 31, 2025. Early adoption is permitted. The standard requires adoption on a retrospective basis for all prior periods presented in the financial statements. The Company does not expect the adoption of this standard to have a significant impact upon the financial statements. In December 2023, the FASB issued ASU 2023-09 to enhance the transparency of income tax disclosures. This guidance requires that public business entities disclose, on an annual basis, specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. A public business entity is required to provide an explanation, if not otherwise evident, of the individual reconciling items disclosed, such as the nature, effect, and underlying causes and the judgment used in categorizing the reconciling items. This guidance also requires that all entities disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by those individual jurisdictions equal to or greater than 5 percent of the total. This standard is effective for the Company for its annual reporting for the year ended December 31, 2025. Early adoption is permitted. The standard requires adoption on a prospective basis, although retrospective adoption is permitted. The Company does not expect the adoption of this standard to have a significant impact upon the financial statements.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	11. Income Taxes Income taxes for the interim periods presented have been included in the accompanying Consolidated Financial Statements on the basis of an estimated annual effective tax rate ("ETR"). The determination of the consolidated provision for income taxes requires management to make certain judgments and estimates. Changes in the estimated level of annual pre-tax earnings or loss, tax laws, and changes resulting from tax audits can affect the overall ETR, which impacts the level of income tax expense or benefit and net income or loss. Judgments and estimates related to the Company’s projections and assumptions are inherently uncertain and therefore, actual results could differ materially from projections. The Company's ETR from continuing operations for the three and nine months ended September 30, 2024 was 24.6% (inclusive of discrete items totaling $0.7 million of tax benefit) and 38.1% (inclusive of discrete items totaling $0.3 million of tax benefit), respectively. The discrete items impacting the tax provision for the three and nine months ended September 30, 2024 were primarily attributable to stock-based compensation and the deferred tax impact of a tax rate change. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2024 was 30.3% and 39.5%, respectively. The Company's ETR from continuing operations for the three and nine months ended September 30, 2023 was (34.5)% (inclusive of discrete items totaling $0.3 million of benefit) and (32.7)% (inclusive of discrete items totaling $0.3 million of expense), respectively. The discrete items impacting the tax provision for the three and nine months ended September 30, 2023 were primarily attributable to stock-based compensation and the recognition of foreign tax credits resulting from the release of IRS Notice 2023-55. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2023 was (31.9)% and (33.7)%, respectively. The Company accrues taxes in various countries where it generates income and applies a valuation allowance in other jurisdictions, which resulted in the provisions and benefits for the three and nine months ended September 30, 2024 and 2023.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	14. Commitments and Contingent Liabilities From time to time, the Company is involved in various legal proceedings and claims arising in the ordinary course of its business. The majority of these claims and proceedings relate to commercial, warranty, employment, and intellectual property matters. Although the ultimate outcome of any legal proceeding or claim cannot be predicted with certainty, based on present information, including management’s assessment of the merits of the particular claim, the Company believes that the disposition of these legal proceedings or claims, individually or in the aggregate, after taking into account recorded accruals and the availability and limits of insurance coverage, will not have a material adverse effect on its cash flow, results of operations, or financial condition. The Company owns many patents and other intellectual property pertaining to its products, technology, and manufacturing processes. Some of the Company's patents have been and may continue to be infringed upon or challenged by others. In appropriate cases, the Company has taken and will take steps to protect and defend its patents and other intellectual property, including through the use of legal proceedings in various jurisdictions around the world. Such steps have resulted in and may continue to result in retaliatory legal proceedings, including litigation or other legal proceedings in various jurisdictions and forums around the world alleging infringement by the Company of patents owned by others. The costs of investigations and legal proceedings relating to the enforcement and defense of the Company’s intellectual property may be substantial. Additionally, in multi-forum disputes, the Company may incur adverse judgments with regard to certain claims in certain jurisdictions and forums while still contesting other related claims against the same opposing party in other jurisdictions and forums. Intellectual Property Infringement Claims The Company may, on a limited basis, provide contractual indemnities for certain losses that arise out of claims that its products infringe on the intellectual property of others. It is not possible to determine the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Historically, the Company has not made significant payments under such indemnity arrangements. The Company’s legal accruals associated with these indemnity arrangements were not significant at September 30, 2024 and December 31, 2023.

Recent Accounting Standards New Accounting Pronouncements, Policy (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	In November 2023, the FASB issued ASU 2023-07 to expand reportable segment disclosure requirements. This guidance requires that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss. All annual disclosures about a reportable segment’s profit or loss and assets currently required by ASC 280 must also be disclosed in interim periods. Additionally, this standard requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This standard is effective for the Company beginning with its annual reporting for the year ended December 31, 2024 and its interim reporting for the three months ended March 31, 2025. Early adoption is permitted. The standard requires adoption on a retrospective basis for all prior periods presented in the financial statements. The Company does not expect the adoption of this standard to have a significant impact upon the financial statements. In December 2023, the FASB issued ASU 2023-09 to enhance the transparency of income tax disclosures. This guidance requires that public business entities disclose, on an annual basis, specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. A public business entity is required to provide an explanation, if not otherwise evident, of the individual reconciling items disclosed, such as the nature, effect, and underlying causes and the judgment used in categorizing the reconciling items. This guidance also requires that all entities disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by those individual jurisdictions equal to or greater than 5 percent of the total. This standard is effective for the Company for its annual reporting for the year ended December 31, 2025. Early adoption is permitted. The standard requires adoption on a prospective basis, although retrospective adoption is permitted. The Company does not expect the adoption of this standard to have a significant impact upon the financial statements.
