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.

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 three months ended March 31, 2023, the Company repurchased 433,759 shares of common stock for a total of $7.5 million. The Company did not repurchase any shares of its common stock during the three months ended March 31, 2024.

Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at March 31, 2024 and 2023 were $0.7 million and $2.3 million, respectively. These non-cash amounts are not reflected as "Capital expenditures" within Investing Activities on the Consolidated Statements of Cash Flows for the respective periods.

Operating lease liabilities arising from obtaining right-of-use assets for the three months ended March 31, 2023 were $1.1 million.

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. 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 8. 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 Accounting Standards Codification 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 three months ended March 31, 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.

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 will be permitted 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 March 31, 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 7.03% and 6.01% for the three months ended March 31, 2024 and 2023, respectively. The weighted-average commitment fee on the revolving line of credit was 0.24% and 0.23% for the three months ended March 31, 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. The Company recognized imputed interest expense on the Seller Note of approximately $2.0 million for the three months ended March 31, 2024.

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.

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 for the three months ended March 31, 2024 and 2023 was 56.1% and (26.8)%, respectively. The ETR includes discrete items totaling $0.8 million and $0.6 million of tax expense for the three months ended March 31, 2024 and 2023, respectively. The discrete items impacting the tax provision for the three months ended March 31, 2024 and 2023 were primarily attributable to stock-based compensation. Absent the discrete items, the ETR for the three months ended March 31, 2024 and 2023 was 42.1% and (12.2)%, respectively. The Company accrues taxes in various countries where it generates income and applies a valuation allowance in other jurisdictions, which resulted in the provisions for the three months ended March 31, 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..

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 customer specific 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 March 31, 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 capacitors and radio frequency ("RF") filtering products, 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, 2023, we announced that we are reviewing strategic alternatives for the CMM business. This includes a range of possibilities, such as: a potential sale, restructuring the business, as well as continuing to operate the business as is. No assurance can be given that any transaction or other strategic outcomes will result from the review. Further, there can be no assurance that the outcome of the strategic alternative review will result in our being able to recover the carrying value of the CMM segment. While the review is progressing, we have not set a timetable for the conclusion of the strategic review and do not intend to comment on or provide updates regarding these matters unless and until we determine that further disclosure is appropriate or required.

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. The acquired business is a manufacturer of film, electrolytic, and mica capacitors used in medtech, defense, and industrial electrification applications. The acquisition's operations are included in the PD segment. For additional information, refer to Note 3. Acquisition to our Consolidated Financial Statements under Part I, Item 1, "Financial Statements."

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 first quarter of 2024 were $196.4 million, compared with $144.3 million for the first quarter of 2023, an increase of $52.1 million or 36.1%. PD revenues increased $20.6 million due to our acquisition of the CD business, partially offset by lower demand from the medtech, industrial, and communication markets in our legacy PD business as a result of continued demand weakness associated with excess customer and channel inventory. CMM revenues increased $19.9 million, primarily due to higher demand in the ear, mobile, and computing markets, partially offset by lower average pricing on mature products. MSA revenues increased $11.6 million, primarily due to higher shipping volumes of hearing health products driven by stronger end market demand. In addition, revenues in the first quarter of 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

Cost of goods sold ("COGS") for the first quarter of 2024 was $125.5 million, compared with $90.4 million for the first quarter of 2023, an increase of $35.1 million or 38.8%. This increase was primarily due to our acquisition of CD, higher shipping volumes, and lower factory capacity utilization in our legacy PD business, partially offset by product cost reductions and favorable foreign currency changes.

Restructuring Charges

During the first quarter of 2024, we recorded restructuring charges of $1.8 million related to headcount reductions and $0.7 million for costs associated with transferring certain capacitors manufacturing to existing facilities to further optimize operations, all within our PD segment. For additional information, refer to Note 7. Restructuring and Related Activities to our Consolidated Financial Statements.

21

During the first quarter of 2023, we recorded restructuring charges of $0.8 million related to headcount reductions in our CMM segment and $0.3 million for other costs. 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 first quarter of 2024 was $69.9 million, compared with $53.8 million for the first quarter of 2023, an increase of $16.1 million or 29.9%. Gross profit margin (gross profit as a percentage of revenues) for the first quarter of 2024 was 35.6%, compared with 37.3% for the first quarter of 2023. The increase in gross profit was primarily due to higher shipping volumes, product cost reductions, our acquisition of CD, favorable foreign currency changes, and higher factory capacity utilization in our CMM segment, partially offset by lower average pricing on mature products shipped into the mobile market, lower factory capacity utilization in our legacy PD business, our acquisition-related costs of CD, and increased restructuring charges. The decrease in gross profit margin was primarily due to lower average pricing on mature products shipped into the mobile market, lower factory capacity utilization in our legacy PD business, our acquisition-related costs of CD, and increased restructuring charges, partially offset by product cost reductions, favorable foreign currency changes, and higher factory capacity utilization in our CMM segment.

Non-GAAP gross profit for the first quarter of 2024 was $74.7 million, compared with $54.4 million for the first quarter of 2023, an increase of $20.3 million or 37.3%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the first quarter of 2024 was 38.0%, compared with 37.7% for the first quarter of 2023. The increase in non-GAAP gross profit was primarily due to higher shipping volumes, product cost reductions, our acquisition of CD, favorable foreign currency changes, and higher factory capacity utilization in our CMM segment, partially offset by lower average pricing on mature products shipped into the mobile market and lower factory capacity utilization in our legacy PD business. The increase in non-GAAP gross profit margin was primarily due to product cost reductions, favorable foreign currency changes, and higher factory capacity utilization in our CMM segment, partially offset by lower average pricing on mature products shipped into the mobile market and lower factory capacity utilization in our legacy PD business.

Research and Development Expenses

Research and development expenses for the first quarter of 2024 were $20.6 million, compared with $20.0 million for the first quarter of 2023, an increase of $0.6 million or 3.0%. Research and development expenses as a percentage of revenues for the first quarter of 2024 and 2023 were 10.5% and 13.9%, respectively. The increase in expenses was primarily driven by our acquisition of the CD business that increased expenses in our PD segment and additional development activities in our MSA segment, partially offset by reduced spending in our CMM segment driven by the benefits of prior year restructuring actions as we continue to shift our focus and spending to our higher margin businesses. The decrease in expenses as a percentage of revenues was driven by our higher revenues.

Selling and Administrative Expenses

Selling and administrative expenses for the first quarter of 2024 were $43.5 million, compared with $33.8 million for the first quarter of 2023, an increase of $9.7 million or 28.7%. Selling and administrative expenses as a percentage of revenues for the first quarter of 2024 and 2023 were 22.1% and 23.4%, respectively. The increase in expenses was primarily driven by our acquisition of CD. The decrease in expenses as a percentage of revenues was driven by higher revenues.

Interest Expense, net

Interest expense for the first quarter of 2024 was $4.4 million, compared with $0.8 million for the first quarter of 2023, an increase of $3.6 million. The increase is primarily due to imputed interest expense on our Seller Note from the CD acquisition, a higher outstanding revolving credit facility balance, and higher interest rates during the first quarter of 2024. For additional information on borrowings and interest expense, refer to Note 8. Borrowings to our Consolidated Financial Statements.

22

Other (Income) Expense, net

Other income for the first quarter of 2024 was $0.4 million, compared with expense of $2.3 million for the first quarter of 2023, a change of $2.7 million. Income in 2024 primarily represents unrealized gains in our investment balances. Expense in 2023 primarily represents unfavorable impacts from foreign currency exchange rate changes, partially offset by the unrealized gains in our investment balances.

Gain on Sale of Asset, net

The gain on sale of asset of $5.4 million is related to the sale of intellectual property previously used in the Intelligent Audio product line, which is included the CMM segment. For additional information, refer to Note 6. Goodwill and Other Intangible Assets.

Provision for Income Taxes and Non-GAAP Provision for Income Taxes

The effective tax rate ("ETR") for the first quarter of 2024 and 2023 was 56.1% and (26.8)%, respectively. The ETR for the first quarter of 2024 and 2023 includes discrete items totaling $0.8 million and $0.6 million of tax expense, respectively. The discrete items impacting the tax provision for 2024 and 2023 are primarily attributable to stock-based compensation. Absent the discrete items, the ETR for the first quarter of 2024 and 2023 was 42.1% and (12.2)%, 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 first quarter of 2024 and 2023, respectively. 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 for the first quarter of 2024 and 2023 was 12.7% and 30.1%, respectively. The non-GAAP ETR includes discrete items totaling $0.7 million and $0.9 million of tax expense for the first quarter of 2024 and 2023, respectively. Absent the discrete items, the non-GAAP ETR for the first quarter of 2024 and 2023 was 9.4% and 17.8%, respectively. The change in the non-GAAP ETR was primarily due to increased utilization of foreign tax credits compared to the prior year.

Net Earnings (Loss)

Net earnings for the first quarter of 2024 were $2.5 million, compared with a $5.2 million loss for the first quarter of 2023, an increase of $7.7 million. As described above, the increase is primarily due to higher gross profit and the gain on sale of asset, partially offset by higher operating expenses and interest expense.

Earnings (Loss) and Adjusted Earnings Before Interest and Income Taxes

Earnings before interest and income taxes ("EBIT") for the first quarter of 2024 was $10.1 million, compared with a $3.3 million loss for the first quarter of 2023, an increase of $13.4 million. EBIT margin (EBIT as a percentage of revenues) for the first quarter of 2024 was 5.1%, compared with (2.3)% for the first quarter of 2023. The change is primarily due to higher gross profit and the gain on sale of asset, partially offset by higher operating expenses.

Adjusted earnings before interest and income taxes ("Adjusted EBIT") for the first quarter of 2024 was $25.7 million, compared with $8.1 million for the first quarter of 2023, an increase of $17.6 million. Adjusted EBIT margin (Adjusted EBIT as a percentage of revenues) for the first quarter of 2024 was 13.1%, compared with 5.6% for the first quarter of 2023. The increases were primarily due to higher non-GAAP gross profit, partially offset by higher non-GAAP operating expenses.

Diluted Earnings (Loss) per Share and Non-GAAP Diluted Earnings per Share

Diluted earnings per share was $0.03 for the first quarter of 2024, compared with loss per share of $0.06 for the first quarter of 2023, an increase of $0.09. As described above, the increase is primarily due to higher gross profit and the gain on sale of asset, partially offset by operating expenses and interest expense.

Non-GAAP diluted earnings per share was $0.20 for the first quarter of 2024, compared with $0.05 for the first quarter of 2023, an increase of $0.15. As described above, the increase was primarily due to higher non-GAAP gross profit partially offset by higher non-GAAP operating expenses and interest expense.

(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 (loss) 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.
(4)    Other expenses include non-recurring professional service fees related to an execution of various reorganization projects, foreign currency exchange rate impacts on restructuring balances, and the ongoing net lease cost (income) related to facilities not used in operations.
(5)    This gain is related to the sale of intellectual property previously used in the Intelligent Audio product line, which is included within the CMM segment.
(6)    Income tax effects of non-GAAP reconciling adjustments are calculated using the applicable tax rates in the jurisdictions of the underlying adjustments.
(7)    The non-GAAP reconciling adjustments are those adjustments made to reconcile Earnings (loss) before interest and income taxes to Adjusted earnings before interest and income taxes.
(8)    The number of shares used in the diluted per share calculations on a non-GAAP basis excludes the impact of stock-based compensation expense expected to be incurred in future periods and not yet recognized in the financial statements, which would otherwise be assumed to be used to repurchase shares under the GAAP treasury stock method.

(1) Production transfer costs represent costs incurred to migrate manufacturing to existing facilities.
(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 $74.3 million for the first quarter of 2024, compared with $53.7 million for the first quarter of 2023, an increase of $20.6 million or 38.4%. Revenues increased due to our acquisition of the CD business, partially offset by lower demand from the medtech, industrial, and communication markets in our legacy PD business as a result of continued demand weakness associated with excess customer and channel inventory.

(Loss) Earnings and Adjusted Earnings Before Interest and Income Taxes

PD loss before interest and income taxes was $2.1 million for the first quarter of 2024, compared with earnings of $10.7 million for the first quarter of 2023, a decrease of $12.8 million. EBIT margin for the first quarter of 2024 was (2.8)%, compared to 19.9% for the first quarter of 2023. The decreases were primarily due to lower gross profit margin and increased operating expenses, partially offset by higher revenues. The gross profit margin decrease was primarily driven by lower factory capacity utilization in our legacy PD business, higher restructuring charges, and the acquisition of CD. In addition, gross profit margins decreased as a result of acquisition-related and production transfer costs associated with the CD business. The increase in operating expenses was primarily driven by the acquisition of the CD business, which includes higher intangible amortization expenses.

PD Adjusted EBIT was $9.8 million for the first quarter of 2024, compared with $13.0 million for the first quarter of 2023, a decrease of $3.2 million. Adjusted EBIT margin for the first quarter of 2024 was 13.2%, compared with 24.2% for the first quarter of 2023. The decreases were primarily due to lower non-GAAP gross profit margin, partially offset by higher revenues. The non-GAAP gross profit margin decrease was primarily driven by lower factory capacity utilization in our legacy PD business and the acquisition of CD.

Revenues

MSA revenues were $57.1 million for the first quarter of 2024, compared with $45.5 million for the first quarter of 2023, an increase of $11.6 million or 25.5%. Revenues increased primarily due to higher shipping volumes of hearing health products driven by stronger end market demand. In addition, revenues in first quarter of 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 Before Interest and Income Taxes

MSA EBIT was $22.7 million for the first quarter of 2024, compared with $11.4 million for the first quarter of 2023, an increase of $11.3 million or 99.1%. EBIT margin for the first quarter of 2024 was 39.8%, compared with 25.1% for the first quarter of 2023. The increases were primarily due to higher revenues and gross profit margins. The higher gross profit margin was driven by favorable product mix and product cost reductions.

MSA Adjusted EBIT was $23.7 million for the first quarter of 2024, compared with $12.3 million for the first quarter of 2023, an increase of $11.4 million. Adjusted EBIT margin for the first quarter of 2024 was 41.5%, compared to 27.0% for the first quarter of 2023. The increases were primarily due to higher revenues and non-GAAP gross profit margins. The higher non-GAAP gross profit margin was driven by favorable product mix and product cost reductions.
