1. Basis of Presentation
Background - Knowles Corporation (NYSE:KN) is a leading manufacturer of specialty electronic components. The Company designs parts that perform unique and critical functions for innovative technologies. Through extreme reliability, custom engineering, and scalable manufacturing, the Company enables businesses to succeed in the most demanding applications across medtech, defense, and industrial markets. Knowles high performance capacitors, radio frequency ("RF") and microwave filters, advanced medtech microphones, and balanced armature speakers enhance the performance of customer products. The Company's focus on the customer, combined with unique technology, proprietary manufacturing techniques, and global operational expertise enable it 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, 2024 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.
On December 27, 2024, the Company completed the sale of the Consumer MEMS Microphones ("CMM") segment to Syntiant Corp. ("Syntiant"). See Note 3. Discontinued Operations for additional information related to this transaction. The results of operations and the related assets and liabilities for CMM have been classified as discontinued operations for all periods presented.
Corrections of Errors - During the six months ended June 30, 2025, the Company identified an error in its historical financial results related to stock-based compensation expense for those individuals that are nearing or have reached retirement eligibility as defined by the equity compensation plan. This error resulted in the understatement of stock-based compensation expense for the years ended December 31, 2024, 2023, and 2022. During the six months ended June 30, 2025, the Company corrected its stock-based compensation expense, which resulted in increases to Selling and administrative expenses of $0.9 million, Research and development expenses of $0.1 million, and Cost of goods sold of $0.1 million. This correction decreased Earnings before income taxes and discontinued operations and Earnings from continuing operations by $1.1 million and $1.0 million, respectively, for the six months ended June 30, 2025.
In addition, during the six months ended June 30, 2025, the Company identified an error in its historical financial results related to working capital adjustments and costs associated with the disposal of the CMM business in the fourth quarter of 2024. This error resulted in the overstatement of the gain on disposal of business reflected in Loss from discontinued operations, net during the year ended December 31, 2024. During the six months ended June 30, 2025, the Company corrected this error, resulting in an increase to Loss from discontinued operations, net of $1.3 million.
The Company evaluated the impact of these errors in accordance with Accounting Standards Codification ("ASC") 250, Accounting Changes and Error Corrections, and determined that they were not material to the consolidated financial statements for the current interim period or to any previously reported annual or interim periods.
Transactions with Syntiant - As partial consideration for the sale of CMM on December 27, 2024, the Company received Series D-2 preferred stock of Syntiant. See Note 3. Discontinued Operations for additional information related to this transaction. The Company accounts for this investment using the cost method, measured at its historical cost of $77.2 million, which was the fair value of the consideration received from Syntiant. This amount is reflected as “Investment in affiliate” on the Consolidated Balance Sheet.

In connection with the sale of CMM, the Company provided financing of $6.4 million to Syntiant, which was utilized to fund Syntiant's requirement to have $40.0 million of cash on its balance sheet at closing. This note is junior to Syntiant's debt financing and matures on March 28, 2029 and bears interest at the prime rate until six months after the closing date of the sale, at which time the interest rate increased to 13.0%. The balance of this note was $5.9 million and $6.4 million as of June 30, 2025 and December 31, 2024, respectively, and is classified within "Other assets and deferred charges" on the Consolidated Balance Sheet.
The Company shares in certain separation costs with Syntiant related to the sale of CMM pursuant to a credit for up to $13.5 million, which it may apply to specified separation costs post-closing. The balance of the separation credit was $8.7 million and $13.5 million at June 30, 2025 and December 31, 2024, respectively and is classified within "Other accrued expenses" on the Consolidated Balance Sheet. Once the separation credit is reduced to $6.5 million, costs will be shared equally by the Company and Syntiant.
The Company leases portions of its facilities to Syntiant, for which lease payments to date of $1.2 million have been applied to the separation credit. The Company also subleases portions of its manufacturing facilities to Syntiant at cost. The portion of operating lease right-of-use assets subleased by Syntiant totaled $5.3 million and $0.3 million at June 30, 2025 and December 31, 2024, respectively.
The Company recognized revenue totaling $4.0 million and $8.3 million during the three and six months ended June 30, 2025, respectively, related to transactions with Syntiant.

The Company recorded an impairment charge of $3.6 million for the three and six months ended June 30, 2025 to write down the carrying value of these assets to fair value based on the expected selling price. This transaction is expected to be completed in the third quarter of 2025.
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.

2. Recent Accounting Standards
In November 2023, the Financial Accounting Standards Board ("FAB") issued Accounting Standards Update ("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. 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. The Company retroactively adopted this standard beginning with its annual reporting for the year ended December 31, 2024 and its interim reporting for the three months ended March 31, 2025. See Note 14. Segment Information.
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.
In November 2024, the FASB issued ASU 2024-03 to provide additional information about specific expense categories in the notes to the financial statements at interim and annual reporting periods. This guidance requires that a public business entity disclose amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption presented on the face of the income statement and a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. This standard also requires an entity disclose the total amount of selling expenses and, in annual reporting periods, an entity's definition of selling expenses. This standard is effective for the Company for its annual reporting for the year ended December 31, 2027 and for interim reporting for the three months ended March 31, 2028. Early adoption is permitted. This standard may be applied either prospectively to the financial statements issued for reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of this ASU on its financial statements.
3. Discontinued Operations
Management and the Board of Directors periodically conduct strategic reviews of the Company’s businesses. On December 27, 2024, the Company completed the sale of the CMM segment to Syntiant. The total consideration for this transaction was approximately $141.9 million, consisting of $63.6 million in cash ($58.0 million net of cash sold), Syntiant Series D-2 preferred stock with a fair value of $77.2 million, and $1.1 million for estimated purchase price adjustments. The Company shares 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. The Company incurred costs to sell related to this transaction of $5.8 million.
As part of its post-transaction review, the Company recorded net adjustments of $1.6 million to the loss on disposal of the CMM business during the six months ended June 30, 2025. This amount includes losses of $1.8 million ($1.3 million, net of tax) related to working capital adjustments and costs associated with the transaction that occurred in the fourth quarter of 2024, but were not recorded at that time.
The disposition of CMM meets the criteria described in 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.

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 Cornell Dubilier ("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.
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 to increase the commitments under the Credit Facility or to establish one or more incremental term loan facilities under the Credit Facility 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.
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 June 30, 2025, 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 was 6.18% and 7.22% for the six months ended June 30, 2025 and 2024, respectively. The weighted-average commitment fee on the revolving line of credit was 0.3% and 0.26% for the six months ended June 30, 2025 and 2024, respectively.

Seller Note
In connection with the acquisition of Cornell Dubilier on November 1, 2023, the Company obtained an interest-free Seller Note from the buyer with aggregate principal payments of $122.9 million. The Company recorded the Seller Note on the acquisition date 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. The Company has made a successful indemnity claim against the Seller Note of $0.2 million. The Company repaid $50.0 million of the Seller Note on November 1, 2024 and the remaining $72.7 million balance is due and payable in cash on November 1, 2025. The Company recognized imputed interest expense on the Seller Note of approximately $1.3 million and $2.0 million for the three months ended June 30, 2025 and 2024, respectively. For the six months ended June 30, 2025 and 2024, the Company recognized imputed interest expense on the Seller Note of approximately $2.5 million and $4.0 million, 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 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.

10. 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 six months ended June 30, 2025 was 31.0% (inclusive of discrete items totaling $0.1 million of tax expense) and 38.8% (inclusive of discrete items totaling $0.3 million of tax benefit), respectively. The discrete items impacting the tax provision for the three and six months ended June 30, 2025 were primarily attributable to stock-based compensation. Absent the discrete items, the ETR from continuing operations for the three and six months ended June 30, 2025 was 30.1% and 41.3%, respectively. The Company's ETR from continuing operations for the three and six months ended June 30, 2024 was 38.5% (inclusive of discrete items totaling $0.1 million of tax expense) and 56.8% (inclusive of discrete items totaling $0.5 million of tax expense), respectively. The discrete items impacting the tax provision for the three and six months ended June 30, 2024 were primarily attributable to stock-based compensation. Absent the discrete items, the ETR from continuing operations for the three and six months ended June 30, 2024 was 37.2% and 51.1%, 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 for the six months ended June 30, 2025 and 2024.
11. Equity Incentive Program
The following table summarizes the stock-based compensation expense recognized by the Company for the periods presented:

| Three Months Ended June 30, |  | Six Months Ended June 30,

(1) The number of RSUs vested includes shares that the Company withheld on behalf of employees to satisfy statutory tax withholding requirements.
At June 30, 2025, $23.9 million of unrecognized compensation expense related to RSUs is expected to be recognized over a weighted-average period of 1.9 years.
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 2025, 2024, and 2023, 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.
On February 18, 2025 the Company granted a special PSU award to its Chief Executive Officer of 81,788 target PSUs, or a grant date fair value of $1.5 million. This award is eligible to vest based on the achievement of a minimum non-GAAP diluted earnings per share amount and specified revenue goals for a three-year performance period. If the goals are not met during the initial three-year period, the performance period may be extended an additional two years at a reduced payout level. Achievement could range from 0% to 400% of the target number of PSUs.
The following table summarizes the Company's PSU activity for the six months ended June 30, 2025:

| Share units |  | Weighted-average grant date fair value
Unvested at December 31, 2024 | 842,866 |  |  | $ | 27.25 |
Granted | 455,018 |  |  | 24.08 |
Vested (1) | (221,616) |  |  | 29.92 |
Unvested at June 30, 2025 | 1,076,268 |  |  | $ | 25.36 |

(1) The number of PSUs vested includes shares that the Company withheld on behalf of employees to satisfy statutory tax withholding requirements.
At June 30, 2025, $12.7 million of unrecognized compensation expense related to PSUs is expected to be recognized over a weighted-average period of 1.7 years.

13. 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 June 30, 2025 and December 31, 2024.

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 leading manufacturer of specialty electronic components. We design parts that perform unique and critical functions for innovative technologies. Through extreme reliability, custom engineering, and scalable manufacturing, we enable businesses to succeed in the most demanding applications across medtech, defense, and industrial markets. Our high performance capacitors, radio frequency ("RF") and microwave filters, advanced medtech microphones, and balanced armature speakers, enhance the performance of our customers products to change, improve, and save lives. 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 April 2, 2025, the U.S. announced a new universal baseline tariff of 10%, plus an additional country-specific tariff for select trading partners, on all U.S. imports. These actions, and retaliatory tariffs imposed by foreign jurisdictions, have resulted in market volatility and uncertainty regarding the ultimate effect of the tariffs on global economic conditions. Based on a preliminary analysis, we do not anticipate that these factors will have a material impact on our operations; however, we continue to monitor changes in international trade relations and trade policy, including those related to tariffs, which could adversely impact our results. We are optimizing operations and leveraging existing programs and strategies to reduce the impact from tariffs. Additionally, we are taking measures to control costs and implementing pricing actions designed to mitigate the risk these policies may have on our revenues and operations.
On December 27, 2024, the Company consummated the sale and assignment of 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 cash ($58.0 million in net cash received) as adjusted for agreed deductions for indebtedness, and working capital and $80.0 million in Syntiant Series D-2 preferred stock (with a fair value of $77.2 million), par value $0.0001. The Company provided $6.4 million in financing, which was utilized to fund Syntiant's requirement to have $40.0 million of cash on its balance sheet at closing. The Company will also share in certain separation costs pursuant to a credit, which Syntiant may apply to specified separation costs post-closing. For additional information, refer to Note 3. Discontinued Operations to our Consolidated Financial Statements under Part I, Item 1, "Financial Statements."
We have reclassified the results of operations and financial position of CMM to discontinued operations for all periods presented. Unless otherwise noted, our results of operations discussed below relate to continuing operations and will be impacted by the CMM divestiture.
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 have incurred 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 have undertaken actions to help ensure that our cost structure is appropriate to support our remaining businesses.
As inventory levels in the industrial markets have recently begun to normalize, our Precision Devices segment has experienced increased bookings for the past three quarters. In addition, with bookings increasing we have seen backlog across our capacitor products increase for the past three quarters.
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 second quarter of 2025 were $145.9 million, compared with $135.2 million for the second quarter of 2024, an increase of $10.7 million or 7.9%. MSA revenues increased $6.3 million, primarily due to higher shipping volumes of metal cans within the specialty audio market that we manufacture and sell to Syntiant as part of our supply agreement associated with the sale of CMM and additional higher shipping volumes into the specialty audio and hearing health markets, partially offset by lower average pricing on mature products. PD revenues increased $4.4 million due to higher demand in the electrification and defense markets, as well as higher average pricing.
Cost of Goods Sold
Cost of goods sold ("COGS") for the second quarter of 2025 was $81.7 million, compared with $77.1 million for the second quarter of 2024, an increase of $4.6 million or 6.0%. This increase was primarily due to higher shipping volumes, unfavorable product mix, production inefficiencies in our CD business as we ramp up our specialty film product line, and unfavorable inventory reserve adjustments, partially offset by company-wide product cost reductions and a reduction of CD related acquisition and production transfer costs.
Impairment Charges
During the second quarter of 2025, we recorded an impairment charge of $3.6 million to write down the carrying value of certain machinery and equipment to fair value. For additional information, refer to Note 1. Basis of Presentation to our Consolidated Financial Statements.
Restructuring Charges
During the second quarter of 2024, we recorded restructuring charges of $0.3 million within Gross profit for costs associated with transferring certain capacitors manufacturing to existing facilities to further optimize operations, and a credit of $0.1 million within Operating expenses related to previous headcount reductions, all within the PD segment. No restructuring charges were recorded during the second quarter of 2025. For additional information, refer to Note 7. Restructuring and Related Activities to our Consolidated Financial Statements.

Gross Profit and Non-GAAP Gross Profit
Gross profit for the second quarter of 2025 was $60.6 million, compared with $57.8 million for the second quarter of 2024, an increase of $2.8 million or 4.8%. Gross profit margin (gross profit as a percentage of revenues) for the second quarter of 2025 was 41.5%, compared with 42.8% for the second quarter of 2024. The increase in gross profit was primarily due to higher shipping volumes, company-wide product cost reductions, a reduction of CD related acquisition and production transfer costs, and higher factory capacity utilization in our legacy PD business, partially offset by impairment charges in 2025, unfavorable product mix, unfavorable inventory reserve adjustments, and production inefficiencies in our CD business as we ramp up our specialty film product line. The decrease in gross profit margin is primarily due to impairment charges in 2025, unfavorable product mix, unfavorable inventory reserve adjustments, and production inefficiencies in our CD business as we ramp up our specialty film product line, partially offset by company-wide product cost reductions, a reduction of CD related acquisition and production transfer costs, and higher factory capacity utilization in our legacy PD business.
Non-GAAP gross profit for the second quarter of 2025 was $64.5 million, compared with $59.8 million for the second quarter of 2024, an increase of $4.7 million or 7.9%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the second quarter of 2025 and 2024 was 44.2%. The increase in non-GAAP gross profit was primarily due to higher shipping volumes, company-wide product cost reductions, and higher factory capacity utilization in our legacy PD business, partially offset by unfavorable product mix, unfavorable inventory reserve adjustments, and production inefficiencies in our CD business as we ramp up our specialty film product line.
Research and Development Expenses
Research and development expenses for the second quarter of 2025 were $10.0 million, compared with $9.6 million for the second quarter of 2024, an increase of $0.4 million or 4.2%. Research and development expenses as a percentage of revenues for the second quarter of 2025 and 2024 were 6.9% and 7.1%, respectively. The increase in expenses was primarily driven by increased development activities in both our PD and MSA segments as we continue to invest in our businesses. The decrease in expenses as a percentage of revenues was driven by higher revenues.
Selling and Administrative Expenses
Selling and administrative expenses for the second quarter of 2025 were $35.9 million, compared with $35.6 million for the second quarter of 2024, an increase of $0.3 million or 0.8%. Selling and administrative expenses as a percentage of revenues for the second quarter of 2025 and 2024 were 24.6% and 26.3%, respectively. The increase in expenses was primarily driven by a change in our deferred compensation liability and higher incentive compensation, partially offset by a reduction of CD related acquisition costs and the benefits of restructuring actions. The decrease in expenses as a percentage of revenues was driven by higher revenues.
Interest Expense, net
Interest expense for the second quarter of 2025 was $2.5 million, compared with $4.6 million for the second quarter of 2024, a decrease of $2.1 million. The decrease is due to a lower outstanding revolving credit facility balance during the second quarter of 2025 and lower imputed interest expense on our Seller Note from the CD acquisition. For additional information on borrowings and interest expense, refer to Note 8. Borrowings to our Consolidated Financial Statements.
Other Expense, net
Other expense for the second quarter of 2025 was $0.9 million, compared with expense of $0.3 million for the second quarter of 2024, a change of $0.6 million. Expense in 2025 and 2024 is primarily due to unfavorable foreign currency exchange rate changes, partially offset by unrealized gains in our investment balances.

Table of Contents
Provision for Income Taxes and Non-GAAP Provision for Income Taxes
The effective tax rate ("ETR") from continuing operations for the second quarter of 2025 and 2024 was 31.0% and 38.5%, respectively. The ETR from continuing operations for the second quarter of 2025 and 2024 includes discrete items totaling $0.1 million of tax expense. The discrete items impacting the tax provision for 2025 and 2024 are primarily attributable to stock-based compensation. Absent the discrete items, the ETR from continuing operations for the second quarter of 2025 and 2024 was 30.1% and 37.2%, 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 for the second quarter of 2025 and 2024. The change in the ETR was due to the mix of earnings and losses by taxing jurisdictions and net discrete items.
The non-GAAP ETR from continuing operations for the second quarter of 2025 and 2024 was 15.9% and 10.7%, respectively. The non-GAAP ETR from continuing operations includes no discrete impact for the second quarter of 2025 or 2024. The change in the non-GAAP ETR was primarily due to decreased utilization of foreign tax credits compared to the prior year.
On July 4, 2025, the One Big Beautiful Bill Act was signed into U.S. federal law. As the law was enacted in the third quarter, there is no tax accounting that was recorded in the second quarter. Based on our initial analysis of the law, we do not anticipate the One Big Beautiful Bill Act having a material impact on the financial statements of Knowles in 2025 or subsequent years, but we will continue to assess and model its impact as the year progresses.
Earnings from Continuing Operations
Earnings from continuing operations for the second quarter of 2025 was $7.8 million, compared with $4.8 million for the second quarter of 2024, an improvement of $3.0 million. As described above, the improvement is primarily due to higher gross profit and lower interest expense, partially offset by higher operating expenses, other expense, and income tax expense.
Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes
Earnings from continuing operations before interest and income taxes ("EBIT") for the second quarter of 2025 was $13.8 million, compared with $12.4 million for the second quarter of 2024, an increase of $1.4 million. EBIT margin (EBIT as a percentage of revenues) for the second quarter of 2025 was 9.5%, compared with 9.2% for the second quarter of 2024. The increase in EBIT and EBIT margin was primarily due to higher gross profit, partially offset by higher operating expenses.
Adjusted earnings before interest and income taxes ("Adjusted EBIT") from continuing operations for the second quarter of 2025 was $27.7 million, compared with $25.2 million for the second quarter of 2024, an increase of $2.5 million. Adjusted EBIT margin (Adjusted EBIT from continuing operations as a percentage of revenues) for the second quarter of 2025 was 19.0%, compared with 18.6% for the second quarter of 2024. The increase in Adjusted EBIT and Adjusted EBIT margin was primarily due to higher non-GAAP gross profit, partially offset by higher non-GAAP operating expenses.
Loss from Discontinued Operations, net
There was no activity for the second quarter of 2025. We recorded a loss of $264.1 million for the second quarter of 2024, primarily driven by goodwill impairment, income tax expense, and additional expenses in connection with the sale of the CMM business, partially offset by a gain on sale of fixed assets. 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 fro m continuing operations was $0.09 for the second quarter of 2025, compared with $0.05 for the second quarter of 2024, an improvement of $0.04. As described above, the improvement is primarily due to higher gross profit and lower interest expense, partially offset by higher operating expenses, other expense, and income tax expense.
Non-GAAP diluted earnings per share from continuing operations was $0.24 for the second quarter of 2025, compared with $0.20 for the second quarter of 2024, an improvement of $0.04. As described above, the improvement is primarily due to higher non-GAAP gross profit and lower interest expense, partially offset by higher non-GAAP operating expenses and higher non-GAAP income tax expense.

Revenues
Revenues for the six months ended June 30, 2025 were $278.1 million, compared with $268.5 million for the six months ended June 30, 2024, an increase of $9.6 million or 3.6%. MSA revenues increased $7.0 million, primarily due to higher shipping volumes of metal cans within the specialty audio market that we manufacture and sell to Syntiant as part of our supply agreement associated with the sale of CMM and additional higher shipping volumes into the specialty audio and hearing health markets, partially offset by lower average pricing on mature products. PD revenues increased $2.6 million due to higher demand from the medtech and electrification markets as well as higher average pricing, partially offset by lower demand from the industrial and defense markets.
Cost of Goods Sold
COGS for the six months ended June 30, 2025 was $160.1 million, compared with $156.2 million for the six months ended June 30, 2024, an increase of $3.9 million or 2.5%. This increase was primarily due to higher shipping volumes, unfavorable product mix, production inefficiencies in our CD business as we ramp up our specialty film product line, and unfavorable inventory reserve adjustments, partially offset by company-wide product cost reductions and a reduction of CD related acquisition and production transfer costs.
Impairment Charges

Gross Profit and Non-GAAP Gross Profit
Gross profit for the six months ended June 30, 2025 was $113.9 million, compared with $111.0 million for the six months ended June 30, 2024, an increase of $2.9 million or 2.6%. Gross profit margin (gross profit as a percentage of revenues) for the six months ended June 30, 2025 was 41.0%, compared with 41.3% for the six months ended June 30, 2024. The increase in gross profit was primarily due to higher shipping volumes, company-wide product cost reductions, a reduction of CD related acquisition and production transfer costs, and lower restructuring charges, partially offset by impairment charges in 2025, unfavorable product mix, unfavorable inventory reserve adjustments, and production inefficiencies in our CD business as we ramp up our specialty film product line. The decrease in gross profit margin is primarily due to impairment charges in 2025, unfavorable product mix, unfavorable inventory reserve adjustments, and production inefficiencies in our CD business as we ramp up our specialty film product line, partially offset by company-wide product cost reductions, a reduction of CD related acquisition and production transfer costs, and lower restructuring charges.
Non-GAAP gross profit for the six months ended June 30, 2025 was $119.5 million, compared with $117.7 million for the six months ended June 30, 2024, an increase of $1.8 million or 1.5%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the six months ended June 30, 2025 was 43.0%, compared with 43.8% for the six months ended June 30, 2024. The increase in non-GAAP gross profit was primarily due to higher shipping volumes and company-wide product cost reductions, partially offset by unfavorable product mix, unfavorable inventory reserve adjustments, and production inefficiencies in our CD business as we ramp up our specialty film product line. The decrease in non-GAAP gross profit margin is primarily due to unfavorable product mix, unfavorable inventory reserve adjustments, and production inefficiencies in our CD business as we ramp up our specialty film product line, partially offset by company-wide product cost reductions.
Research and Development Expenses
Research and development expenses for the six months ended June 30, 2025 were $19.7 million, compared with $19.0 million for the six months ended June 30, 2024, an increase of $0.7 million or 3.7%. Research and development expenses as a percentage of revenues for the six months ended June 30, 2025 and 2024 was 7.1%. The increase in expenses was primarily driven by increased development activities in both our MSA and PD segments as we continue to invest in our businesses.
Selling and Administrative Expenses
Selling and administrative expenses for the six months ended June 30, 2025 were $73.1 million, compared with $72.9 million for the six months ended June 30, 2024, an increase of $0.2 million or 0.3%. Selling and administrative expenses as a percentage of revenues for the six months ended June 30, 2025 and 2024 were 26.3% and 27.2%, respectively. The increase in expenses was primarily driven by the acceleration of stock-based compensation expense for employees who are nearing or have reached retirement eligibility and higher incentive compensation, partially offset by the benefits of restructuring actions, a reduction of CD related acquisition costs, and reduced intangible amortization costs. The decrease in expenses as a percentage of revenues was driven by higher revenues.
Interest Expense, net
Interest expense for the six months ended June 30, 2025 was $5.2 million, compared with $9.0 million for the six months ended June 30, 2024, a decrease of $3.8 million. The decrease is due to a lower outstanding revolving credit facility balance during the six months ended June 30, 2025 and lower imputed interest expense on our Seller Note from the CD acquisition. For additional information on borrowings and interest expense, refer to Note 8. Borrowings to our Consolidated Financial Statements.

Other Expense (Income), net
Other expense for the six months ended June 30, 2025 was $1.4 million, compared with income of $0.1 million for the six months ended June 30, 2024, a change of $1.5 million. Expense for the six months ended June 30, 2025 primarily represents unfavorable foreign currency changes, partially offset by unrealized gains in our investment balances. Income in the six months ended June 30, 2024 primarily represents unrealized gains in our investment balances, partially offset by unfavorable foreign currency changes.
Provision for Income Taxes and Non-GAAP Provision for Income Taxes
The ETR from continuing operations for the six months ended June 30, 2025 and 2024 was 38.8% and 56.8%, respectively. The ETR from continuing operations for the six months ended June 30, 2025 and 2024 includes discrete items totaling $0.3 million of tax benefit and $0.5 million of tax expense, respectively. The discrete items impacting the tax provision for 2025 and 2024 are primarily attributable to stock-based compensation. Absent the discrete items, the ETR from continuing operations for the six months ended June 30, 2025 and 2024 was 41.3% and 51.1%, 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 for the six months ended June 30, 2025 and 2024. The change in the ETR was mainly due to the mix of earnings and losses by taxing jurisdictions and net discrete items.
The non-GAAP ETR from continuing operations for the six months ended June 30, 2025 and 2024 was 15.4% and 10.4%, respectively. The non-GAAP ETR from continuing operations includes no discrete impact for the six months ended June 30, 2025 and 2024. The change in the non-GAAP ETR was primarily due to decreased utilization of foreign tax credits compared to the prior year.
Earnings from Continuing Operations
Earnings from continuing operations for the six months ended June 30, 2025 was $7.4 million, compared with $3.8 million for the six months ended June 30, 2024, an improvement of $3.6 million. As described above, the improvement is primarily due to lower interest expense and higher gross profit, partially offset by higher operating expenses and other expense in the six months ended June 30, 2025 compared to other income for the six months ended June 30, 2024.
Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes
EBIT for the six months ended June 30, 2025 was $17.3 million, compared with $17.8 million for the six months ended June 30, 2024, a decrease of $0.5 million. EBIT margin for the six months ended June 30, 2025 was 6.2%, compared with 6.6% for the six months ended June 30, 2024. The decrease in EBIT was primarily due to higher operating and other expenses, partially offset by higher gross profit. The decrease in EBIT margin was primarily due to higher operating expenses, increased other expenses, and lower gross profit margin.
Adjusted EBIT from continuing operations for the six months ended June 30, 2025 was $49.4 million, compared with $48.5 million for the six months ended June 30, 2024, an increase of $0.9 million. Adjusted EBIT margin for the six months ended June 30, 2025 was 17.8%, compared with 18.1% for the six months ended June 30, 2024. The increase in Adjusted EBIT was primarily due to higher non-GAAP gross profit, partially offset by higher non-GAAP operating expenses. The decrease in Adjusted EBIT margin was primarily driven by higher non-GAAP operating expenses and lower gross profit margin.
Loss from Discontinued Operations, net
Loss from discontinued operations for the six months ended June 30, 2025 was $1.6 million, compared with a loss of $260.6 million for the six months ended June 30, 2024, an increase of $259.0 million. Loss from discontinued operations for the six months ended June 30, 2025 was primarily driven by unfavorable working capital adjustments. Loss from discontinued operations for the six months ended June 30, 2024 was primarily driven by goodwill impairment, income tax expense, and additional expenses in connection with the sale of the CMM business, partially offset by the gain on sale of technology and gain on sale of fixed assets.

(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.
(3) These expenses are related to the acquisition of CD by the PD segment. These expenses include ongoing costs to facilitate integration, the amortization of fair value adjustments to inventory, and costs incurred by the Company to carry out this transaction.

EBIT margin for the second quarter of 2025 was 31.2%, compared with 39.4% for the second quarter of 2024. The decreases were primarily due to lower gross profit and higher operating expenses. The gross profit decrease was primarily due to impairment charges recorded in the second quarter of 2025, lower average pricing on mature products, unfavorable product mix, higher factory costs, and the impact of higher shipping volumes of our lower margin metal can products to Syntiant, partially offset by higher shipping volumes. The increase in operating expenses was primarily driven by higher stock-based compensation and legal costs.
MSA Adjusted EBIT was $26.1 million for the second quarter of 2025, compared with $25.1 million for the second quarter of 2024, an increase of $1.0 million. Adjusted EBIT margin for the second quarter of 2025 was 38.7%, compared to 41.1% for the second quarter of 2024. The increase in adjusted EBIT was primarily due to higher non-GAAP gross profit driven by higher shipping volumes, partially offset by lower average pricing on mature products, unfavorable product mix, and higher factory costs. The decrease in Adjusted EBIT margin was primarily due to lower average pricing on mature products, unfavorable product mix, higher factory costs, and the impact of higher shipping volumes of our lower margin metal can products to Syntiant.

MSA revenues were $127.1 million for the six months ended June 30, 2025, compared with $120.1 million for the six months ended June 30, 2024, an increase of $7.0 million or 5.8%. Revenues increased primarily due to higher shipping volumes of metal cans within the specialty audio market that we manufacture and sell to Syntiant as part of our supply agreement associated with the sale of CMM and additional higher shipping volumes into the specialty audio and hearing health markets, partially offset by lower average pricing on mature products.
Earnings and Adjusted Earnings Before Interest and Income Taxes
MSA EBIT was $40.3 million for the six months ended June 30, 2025, compared with $46.9 million for the six months ended June 30, 2024, a decrease of $6.6 million or 14.1%. EBIT margin for the six months ended June 30, 2025 was 31.7%, compared with 39.1% for the six months ended June 30, 2024. The decreases were primarily due to lower gross profit and higher operating expenses. The gross profit decrease was primarily due to impairment charges recorded in the second quarter of 2025, lower average pricing on mature products, unfavorable product mix, higher factory costs, and the impact of higher shipping volumes of our lower margin metal can products to Syntiant, partially offset by higher shipping volumes. The increase in operating expenses was primarily driven by higher stock-based compensation and legal costs.
MSA Adjusted EBIT was $47.4 million for the six months ended June 30, 2025, compared with $48.9 million for the six months ended June 30, 2024, a decrease of $1.5 million. Adjusted EBIT margin for the six months ended June 30, 2025 was 37.3%, compared to 40.7% for the six months ended June 30, 2024. The decreases were primarily due to lower non-GAAP gross profit and higher non-GAAP operating expenses. The decrease in non-GAAP gross profit was primarily due to lower average pricing on mature products, unfavorable product mix, higher factory costs, and the impact of higher shipping volumes of our lower margin metal can products to Syntiant, partially offset by higher shipping volumes. The increase in non-GAAP operating expenses was primarily driven by higher legal costs.

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 $103.2 million and $130.1 million at June 30, 2025 and December 31, 2024, respectively. Of these amounts, cash held by our non-U.S. operations totaled $31.8 million and $92.4 million as of June 30, 2025 and December 31, 2024, 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.
On December 27, 2024, we completed the sale of the CMM segment to Syntiant for approximately $141.9 million in total consideration, consisting of $63.6 million in cash ($58.0 million net of cash sold), $1.1 million for estimated purchase price adjustments, and Series D-2 preferred stock of Syntiant with a fair value of $77.2 million. For additional information, refer to Note 3. Discontinued Operations to our Consolidated Financial Statements. We 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. For additional information, refer to Note 1. Basis of Presentation.
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. On February 13, 2025, the Company announced another authorization increase of up to $150.0 million in additional aggregate value. At June 30, 2025, we have $159.0 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. Any shares repurchased will be held as treasury stock. During the six months ended June 30, 2025 and 2024, the Company repurchased 2,182,462 and 1,432,989 shares of common stock, respectively, for a total of $35.0 million and $25.0 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:

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 decrease in cash provided by operating activities in 2025 is primarily due to $29.3 million of payments to settle supplier obligations and separation costs related to the CMM business and higher restructuring payments, partially offset by customer prepayments of $19.8 million and lower incentive compensation payments.
Investing Activities
The cash used in investing activities during 2025 was driven by capital expenditures, which is primarily driven by capacity expansion related to our specialty film product line and cost savings. The cash provided by investing activities during 2024 was primarily driven by proceeds from the sale of intellectual property, partially offset by capital expenditures to support product innovation and cost savings.
In 2025, we expect capital expenditures to be in the range o f 4% to 6% o f revenue s.
Financing Activities
Cash used in financing activities during 2025 was primarily related to $35.0 million of repurchases of common stock, $15.0 million of payments on the revolving credit facility, and $6.9 million of tax payments related to net share settlement of equity awards, partially offset by proceeds of $0.6 million from the exercise of options. Cash used in financing activities during 2024 was primarily related to $25.0 million of repurchases of common stock, $14.0 million of net payments on the revolving credit facility, and $5.9 million payment of taxes related to net share settlement of equity awards.
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 generated or utilized by 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:

|  | Six Months Ended June 30,
(in millions) |  | 2025 |  | 2024
Net cash provided by operating activities |  | $ | 37.7 |  |  | $ | 42.2 |
Less: amounts utilized by discontinued operations |  | 29.3 |  |  | 0.2 |
Non-GAAP net cash attributable to continuing operations |  | 67.0 |  |  | 42.4 |
Capital expenditures |  | (9.1) |  |  | (6.6) |
Less: amounts attributable to discontinued operations |  | — |  |  | 0.7 |
Non-GAAP capital expenditures attributable to continuing operations |  | (9.1) |  |  | (5.9) |
Non-GAAP net cash attributable to continuing operations |  | 67.0 |  |  | 42.4 |
Non-GAAP capital expenditures attributable to continuing operations |  | (9.1) |  |  | (5.9) |
Adjusted free cash flow |  | $ | 57.9 |  |  | $ | 36.5 |
Adjusted free cash flow as a % of revenues |  | 20.8 | % |  | 13.6 | %

In 2025 we generated adjusted free cash flow of $57.9 compared to adjusted free cash flow of $36.5 million in 2024. The increase in adjusted free cash flow in 2025 was primarily due to customer prepayments of $19.8 million and lower incentive compensation payments, partially offset by higher restructuring payments.
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 13. 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.
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, 2024 filed with the Securities and Exchange Commission on February 13, 2025. 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 six months ended June 30, 2025, 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, 2024. For a discussion of our exposure to market risk as of December 31, 2024, 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, 2024.
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 second quarter of 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
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.
