1. Basis of Presentation

Background - Knowles Corporation (NYSE:KN) is a market leader and global provider of advanced micro-acoustic microphones and balanced armature speakers, audio solutions, and high performance capacitors and radio frequency ("RF") products, serving the consumer electronics, medtech, defense, electric vehicle, industrial, and communications 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, 2022 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 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 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 and 2022, the Company repurchased 433,759 shares and 313,395 shares of common stock, respectively, for a total of $7.5 million and $6.8 million, respectively.

Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at March 31, 2023 and 2022 were $2.3 million and $3.2 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.

8. Borrowings

Revolving Credit Facility

Revolving credit facility borrowings consist of the following:

Revolving credit facility	$	45.0	$	45.0
Less current maturities (1)	—		—
Total long-term debt	$	45.0	$	45.0

(1) There are no required principal payments due until maturity in February 2028.

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 (the “2020 Credit Facility”), 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.

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, 2023, 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 6.01% and 2.12% for the three months ended March 31, 2023 and 2022, respectively. The weighted-average commitment fee on the revolving line of credit was 0.23% and 0.24% for the three months ended March 31, 2023 and 2022, respectively.

Warrants

In the second quarter of 2016, the Company entered into warrant transactions, whereby the Company sold warrants to acquire shares of the Company's common stock at a strike price of $21.1050 per share (the “Warrants”). The Company received aggregate proceeds of $39.1 million from the sale of the Warrants. The Warrants were separate transactions entered into by the Company, and were not part of the Notes, and were accounted for as part of additional paid-in capital.

The Warrants expired during the first quarter of 2022, which resulted in the Company delivering 0.2 million shares of its common stock held in treasury. Settlement of the Warrants resulted in a $3.1 million decrease in treasury stock, which was measured based on the acquisition cost of the delivered shares determined on a first-in, first-out (“FIFO”) basis, offset by an equivalent decrease in additional paid-in capital with no net impact to equity.

9. Other Comprehensive Earnings

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, 2023 and 2022 was (26.8)% and 13.8%, respectively. The ETR includes discrete items totaling $0.6 million of tax expense and $1.0 million of tax benefit for the three months ended March 31, 2023 and 2022, respectively. The discrete items impacting the tax provision for the three months ended March 31, 2023 and 2022 were primarily attributable to stock-based compensation. Absent the discrete items, the ETR for the three months ended March 31, 2023 and 2022 was (12.2)% and 18.6%, 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, 2023 and 2022.

The Company's ETR is favorably impacted by tax holidays granted to the Company. The benefit for these incentives for the three months ended March 31, 2023 was approximately $0.1 million, with no impact to basic earnings per share. The benefit for these incentives for the three months ended March 31, 2022 was approximately $2.6 million, or $0.03 on a basic per share basis. The decrease in the tax holiday benefits is attributable to the Company not satisfying all of the conditions of our tax holiday in Malaysia during the year ended December 31, 2022 due to the rapid decline in demand for global consumer electronics. As a result, our tax holiday benefit in Malaysia ended on December 31, 2022 and the Company is currently in appeal discussions with the Malaysian tax authorities regarding revised conditions.

11. Equity Incentive Program

Stock-based compensation expense recognized in the Consolidated Statements of Earnings totaled $7.8 million and $7.6 million for the three months ended March 31, 2023 and 2022, respectively. The tax benefit recognized related to stock-based compensation expense was $2.9 million and $3.2 million for the three months ended March 31, 2023 and 2022, respectively.

At March 31, 2023, $34.9 million of unrecognized compensation expense related to RSUs is expected to be recognized over a weighted-average period of 2.1 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 2023, 2022, and 2021, the number of PSUs that may be earned and vest is based on total shareholder return (“TSR”) relative to the component companies of the Russell 2000 Index over a three-year performance period.

The following table summarizes the Company's PSU activity for the three months ended March 31, 2023:

	Share units	Weighted-average grant date fair value
Unvested at December 31, 2022	833,589	$	25.12
Granted	320,585	29.75
Vested (1)	(261,770)	16.14
Forfeited	—	—
Unvested at March 31, 2023	892,404	$	29.42

(1) The number of PSUs vested includes shares that the Company withheld on behalf of employees to satisfy statutory tax withholding requirements.

At March 31, 2023, $16.8 million of unrecognized compensation expense related to PSUs is expected to be recognized over a weighted-average period of 1.9 years.

12. Earnings per Share

Basic and diluted earnings per share were computed as follows:

	Three Months Ended March 31,
(in millions, except per share amounts)	2023		2022
Net (loss) earnings	$	(5.2)	$	18.1
Basic:

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, 2023 and December 31, 2022.

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 advanced micro-acoustic microphones and balanced armature speakers, audio solutions, and high performance capacitors and radio frequency ("RF") filtering products, serving the medtech, defense, consumer electronics, electric vehicle, industrial, and communications 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.

During the fourth quarter of 2022, we determined each operating segment represents a single reportable segment; thus, we now report three segments. These segments were determined in accordance with Financial Accounting Standards Board Accounting Standards Codification 280 - Segment Reporting and are comprised of (i) Precision Devices ("PD"), (ii) MedTech & Specialty Audio ("MSA"), and (iii) Consumer MEMS Microphones ("CMM"). The segments are aligned around similar product applications serving our key end markets to enhance focus on end market growth strategies.

•PD Segment

Our PD segment specializes in the design and delivery of high performance capacitor products and RF solutions primarily serving the defense, medtech, electric vehicle, and industrial markets. PD has sales, support, and engineering facilities in North America, Europe, and Asia as well as manufacturing facilities in North America and Asia.

•MSA Segment

Our MSA segment designs and manufactures microphones and balanced armature speakers used in applications that serve the hearing health and premium audio markets. MSA has sales, support, and engineering facilities in North America, Europe, and Asia, as well as manufacturing facilities in Asia.

•CMM Segment

Our CMM segment designs and manufactures micro-electro-mechanical systems ("MEMS") microphones and audio solutions used in applications that primarily serve the ear, Internet of Things ("IoT"), computing, and smartphone markets. CMM has sales, support, and engineering facilities in North America, Europe, and Asia, as well as manufacturing facilities in Asia.

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

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 2023 were $144.3 million, compared with $201.4 million for the first quarter of 2022, a decrease of $57.1 million or 28.4%. CMM revenues decreased $41.1 million, primarily due to lower demand for MEMS microphones in the mobile, IoT, computing, and ear markets. The decreases in these markets were primarily driven by weak global demand for consumer electronics and excess inventory in the supply chain. In addition to lower end market demand, shipping volumes were unfavorably impacted this quarter by financial incentives offered to customers resulting in higher shipping volumes in the fourth quarter of 2022. CMM revenues were also impacted by lower average pricing on mature products shipped into the mobile market. MSA revenues decreased $14.0 million, primarily due to lower shipping volumes into the hearing health and premium audio markets as customers reduced their inventory levels. In addition to lower end market demand, shipping volumes were unfavorably impacted this quarter by financial incentives offered to customers resulting in higher shipping volumes in the fourth quarter of 2022. PD revenues decreased $2.0 million, primarily due to lower demand from the industrial and communication markets, partially offset by increased demand in the electric vehicle and medtech markets.

Cost of Goods Sold

Cost of goods sold ("COGS") for the first quarter of 2023 was $90.4 million, compared with $118.1 million for the first quarter of 2022, a decrease of $27.7 million or 23.5%. This decrease was primarily due to lower shipping volumes, product cost reductions, benefits of prior year restructuring actions, favorable foreign currency exchange rate changes, and a decrease in precious metal costs, partially offset by lower factory capacity utilization and unfavorable product mix.

19

Restructuring Charges

During the first quarter of 2023, we recorded restructuring charges of $0.8 million for severance pay and benefits to rationalize 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.

During the first quarter of 2022, we restructured our MEMS Microphones product line, which is included within the CMM segment. This action resulted in the termination of a research and development project and a reduction in workforce. We recorded restructuring charges of $5.4 million related to this action. In addition, we recorded restructuring charges of $1.2 million to rationalize the Intelligent Audio product line workforce, which is also included within the CMM segment. 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 2023 was $53.8 million, compared with $83.3 million for the first quarter of 2022, a decrease of $29.5 million or 35.4%. Gross profit margin (gross profit as a percentage of revenues) for the first quarter of 2023 was 37.3%, compared with 41.4% for the first quarter of 2022. The decrease in gross profit was primarily due to lower shipping volumes. The decrease in gross profit margin was due to lower factory capacity utilization, unfavorable product mix, lower average pricing on mature products shipped into the mobile market, partially offset by product cost reductions, benefits of prior year restructuring actions, favorable foreign currency exchange rate changes, and a decrease in precious metal costs.

Non-GAAP gross profit for the first quarter of 2023 was $54.4 million, compared with $83.8 million for the first quarter of 2022, a decrease of $29.4 million or 35.1%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the first quarter of 2023 was 37.7%, compared with 41.6% for the first quarter of 2022. The decrease in non-GAAP gross profit was primarily due to lower shipping volumes. The decrease in non-GAAP gross profit margin was primarily due to lower factory capacity utilization, unfavorable product mix, and lower average pricing on mature products shipped into the mobile market, partially offset by product cost reductions, benefits of prior year restructuring actions, favorable foreign currency exchange rate changes, and a decrease in precious metal costs.

Research and Development Expenses

Research and development expenses for the first quarter of 2023 were $20.0 million, compared with $23.1 million for the first quarter of 2022, a decrease of $3.1 million or 13.4%. Research and development expenses as a percentage of revenues for the first quarter of 2023 and 2022 were 13.9% and 11.5%, respectively. The decrease in expenses was primarily driven by reduced spending in our CMM segment driven by the benefits of prior year restructuring actions, partially offset by increased development activities in our PD segment. The increase in expenses as a percentage of revenues was driven by our lower revenues.

Selling and Administrative Expenses

Selling and administrative expenses for the first quarter of 2023 were $33.8 million, compared with $32.3 million for the first quarter of 2022, an increase of $1.5 million or 4.6%. Selling and administrative expenses as a percentage of revenues for the first quarter of 2023 and 2022 were 23.4% and 16.0%, respectively. The increase in expenses was primarily driven by a change in our deferred compensation liability and increased travel activity. The increase in expenses as a percentage of revenues was driven by our lower revenues.

Interest Expense, net

Interest expense for the first quarter of 2023 and 2022 was $0.8 million. We had a lower outstanding revolving credit facility balance during the first quarter of 2023 compared to the first quarter of 2022, offset by higher interest rates. 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 first quarter of 2023 was $2.3 million, compared with income of $0.5 million for the first quarter of 2022, a change of $2.8 million. The change is primarily due to unfavorable impacts from foreign currency exchange rate changes, partially offset by the appreciation in our investment balances.

20

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

The effective tax rate ("ETR") for the first quarter of 2023 and 2022 was (26.8)% and 13.8%, respectively. The ETR for the first quarter of 2023 and 2022 includes discrete items totaling $0.6 million of tax expense and $1.0 million of tax benefit, respectively. The discrete items impacting the tax provision for first quarter of 2023 and 2022 are primarily attributable to stock-based compensation. Absent the discrete items, the ETR for the first quarter of 2023 and 2022 was (12.2)% and 18.6%, 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 2023 and 2022. 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 2023 and 2022 was 30.1% and 13.0%, respectively. The non-GAAP ETR includes discrete items totaling $0.9 million of tax expense for the first quarter of 2023. Absent the discrete items, the non-GAAP ETR for the first quarter of 2023 and 2022 was 17.8% and 13.0%, respectively. The change in the non-GAAP ETR was due to lower pre-tax earnings and net discrete items including the impact of the increase in our Malaysian tax rate on our 2022 non-GAAP provision.

The ETR and non-GAAP ETR deviate from the statutory U.S. federal income tax rate, mainly due to the taxing jurisdictions where we generate taxable income or loss. As a result of the rapid decline in demand for global consumer electronics during 2022, we did not satisfy all of the conditions of our tax holiday in Malaysia. As such, we are not including this tax holiday benefit in our 2023 GAAP ETR and non-GAAP ETR. We are currently in appeal discussions with the Malaysian tax authorities regarding revised conditions. For additional information on these tax holidays refer to Note 10. Income Taxes to our Consolidated Financial Statements.

Net (Loss) Earnings

Net loss for the first quarter of 2023 was $5.2 million, compared with earnings of $18.1 million for the first quarter of 2022, a decrease of $23.3 million. As described above, the decrease is primarily due lower gross profit, partially offset by lower operating expenses and restructuring charges.

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

Loss before interest and income taxes for the first quarter of 2023 was $3.3 million, compared with earnings of $21.8 million for the first quarter of 2022, a decrease of $25.1 million. (Loss) earnings before interest and income taxes ("EBIT") margin (EBIT as a percentage of revenues) for the first quarter of 2023 was (2.3)%, compared with 10.8% for the first quarter of 2022. The decreases are primarily due to lower gross profit, partially offset by lower operating expenses and restructuring charges.

Adjusted earnings before interest and income taxes ("Adjusted EBIT") for the first quarter of 2023 was $8.1 million, compared with $39.4 million for the first quarter of 2022, a decrease of $31.3 million. Adjusted EBIT margin (Adjusted EBIT as a percentage of revenues) for the first quarter of 2023 was 5.6%, compared with 19.6% for the first quarter of 2022. The decreases were primarily due to lower non-GAAP gross profit, partially offset by lower non-GAAP operating expenses.

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

Diluted loss per share was $0.06 for the first quarter of 2023, compared with earnings per share of $0.19 for the first quarter of 2022, a decrease of $0.25. As described above, the decrease is primarily due to lower gross profit, partially offset by lower operating expenses and restructuring charges.

Non-GAAP diluted earnings per share was $0.05 for the first quarter of 2023, compared with $0.35 for the first quarter of 2022, a decrease of $0.30. As described above, the decrease was primarily due to lower non-GAAP gross profit, partially offset by lower non-GAAP operating expenses.

(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)    Other expenses represent the ongoing net lease cost related to facilities not used in operations

(3)    Income tax effects of non-GAAP reconciling adjustments are calculated using the applicable tax rates in the jurisdictions of the underlying adjustments.

(4)    The non-GAAP reconciling adjustments are those adjustments made to reconcile (Loss) earnings before interest and income taxes to Adjusted earnings before interest and income taxes.

(5)    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.

Segment Results of Operations for the Three Months Ended March 31, 2023 compared with the Three Months Ended March 31, 2022

The following is a summary of the results of operations of our three reportable segments: Precision Devices, Medtech & Specialty Audio, and Consumer MEMS Microphones.

See Note 14. Segment Information to the Consolidated Financial Statements for (i) a reconciliation of segment revenues to our consolidated revenues and (ii) a reconciliation of segment earnings before interest and income taxes to our consolidated earnings.

Precision Devices

	Three Months Ended March 31,
(in millions)	2023		Percent of Revenues	2022		Percent of Revenues
Revenues	$	53.7		$	55.7
Earnings before interest and income taxes	$	10.7	19.9%	$	12.3	22.1%

Intangibles amortization expense	1.4			1.5
Adjusted earnings before interest and income taxes	$	13.0	24.2%	$	14.5	26.0%

Revenues

PD revenues were $53.7 million for the first quarter of 2023, compared with $55.7 million for the first quarter of 2022, a decrease of $2.0 million or 3.6%. Revenues decreased primarily due to lower demand from the industrial and communication markets, partially offset by increased demand in the electric vehicle and medtech markets.

Earnings and Adjusted Earnings Before Interest and Income Taxes

PD EBIT was $10.7 million for the first quarter of 2023, compared with earnings of $12.3 million for the first quarter of 2022, a decrease of $1.6 million. EBIT margin for the first quarter of 2023 was 19.9%, compared to 22.1% for the first quarter of 2022. The decreases were primarily due to lower revenues and increased operating expenses, partially offset by higher gross profit margins. The gross profit margin increase was primarily driven by a decrease in precious metal costs and product cost reductions.

PD Adjusted EBIT was $13.0 million for the first quarter of 2023, compared with $14.5 million for the first quarter of 2022, a decrease of $1.5 million. Adjusted EBIT margin for the first quarter of 2023 was 24.2%, compared with 26.0% for the first quarter of 2022. The decreases were primarily due to lower revenues and increased operating expenses, partially offset by higher non-GAAP gross profit margins. The non-GAAP gross profit margin increase was primarily driven by a decrease in precious metal costs and product cost reductions.

MedTech & Specialty Audio

	Three Months Ended March 31,

Revenues	$	45.5		$	59.5
Earnings before interest and income taxes	$	11.4	25.1%	$	21.7	36.5%
Stock-based compensation expense	0.9			0.7
Adjusted earnings before interest and income taxes	$	12.3	27.0%	$	22.4	37.6%

Revenues

MSA revenues were $45.5 million for the first quarter of 2023, compared with $59.5 million for the first quarter of 2022, a decrease of $14.0 million or 23.5%. Revenues decreased primarily due to lower shipping volumes into the hearing health and premium audio markets as customers reduced their inventory levels. In addition to lower end market demand, shipping volumes were unfavorably impacted this quarter by financial incentives offered to customers resulting in higher shipping volumes in the fourth quarter of 2022.

Earnings and Adjusted Earnings Before Interest and Income Taxes

MSA EBIT was $11.4 million for the first quarter of 2023, compared with earnings of $21.7 million for the first quarter of 2022, a decrease of $10.3 million or 47.5%. EBIT margin for the first quarter of 2023 was 25.1%, compared with 36.5% for the first quarter of 2022. The decreases were primarily due to lower revenues and lower gross profit margins. The lower gross profit margin was driven by lower factory capacity utilization, unfavorable product mix, and inflationary impacts, partially offset by product cost reductions and favorable foreign currency exchange rate changes.

MSA Adjusted EBIT was $12.3 million for the first quarter of 2023, compared with $22.4 million for the first quarter of 2022, a decrease of $10.1 million. Adjusted EBIT margin for the first quarter of 2023 was 27.0%, compared to 37.6% for the first quarter of 2022. The decreases were primarily due to lower revenues and lower non-GAAP gross profit margins. The lower non-GAAP gross profit margin was driven by lower factory capacity utilization, unfavorable product mix, and inflationary impacts, partially offset by product cost reductions and favorable foreign currency exchange rate changes.

Revenues

CMM revenues were $45.1 million for the first quarter of 2023, compared with $86.2 million for the first quarter of 2022, a decrease of $41.1 million or 47.7%. Revenues decreased primarily due to lower demand for MEMS microphones in the mobile, IoT, computing, and ear markets. The decreases in these markets were primarily driven by weak global demand for consumer electronics and excess inventory in the supply chain. In addition to lower end market demand, shipping volumes were unfavorably impacted this quarter by financial incentives offered to customers resulting in higher shipping volumes in the fourth quarter of 2022. Revenues were also impacted by lower average pricing on mature products shipped into the mobile market.

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

CMM loss before interest and income taxes was $8.2 million for the first quarter of 2023, compared with earnings of $0.5 million for the first quarter of 2022, a decrease of $8.7 million. EBIT margin for the first quarter of 2023 was (18.2)%, compared with 0.6% for the first quarter of 2022. The decreases were primarily due to lower revenues and gross profit margins, partially offset by lower restructuring charges and lower operating expenses. The lower gross profit margin was driven by decreased factory capacity utilization, lower average pricing on mature products shipped into the mobile market, and unfavorable product mix, partially offset by the benefits of prior year restructuring actions and product cost reductions.

CMM Adjusted loss before interest and income taxes was $4.6 million for the first quarter of 2023, compared with earnings of $10.9 million for the first quarter of 2022, a decrease of $15.5 million. Adjusted EBIT margin for the first quarter of 2023 was a loss of 10.2%, compared to earnings of 12.6% for the first quarter of 2022. The decreases were primarily due to lower revenues and non-GAAP gross profit margins, partially offset by lower operating expenses. The lower gross profit margin was driven by decreased factory capacity utilization, lower average pricing on mature products shipped into the mobile market, and unfavorable product mix, partially offset by the benefits of prior year restructuring actions and product cost reductions.

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 significant portion of our cash is generated and typically held outside the United States. Our cash and cash equivalents totaled $52.0 million and $48.2 million at March 31, 2023 and December 31, 2022, respectively. Of these amounts, cash held by our non-U.S. operations totaled $44.9 million and $40.0 million as of March 31, 2023 and December 31, 2022, 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 February 8, 2023, we entered into an Amended and Restated Credit Agreement (the "A&R Credit Agreement") that amends and restates the prior Credit Agreement (the "2020 Credit Agreement"), which provides for a senior secured revolving credit facility with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. As of March 31, 2023, outstanding borrowings under the Credit Facility were $45.0 million. At any time during the term of the Credit Facility, we will be permitted to increase the commitments under the Credit Facility or to establish one or more incremental term loan facilities under the New Credit Facility in an aggregate principal amount not to exceed $200.0 million for all such incremental facilities. Commitments under the Credit Facility will terminate, and loans outstanding thereunder will mature, on February 8, 2028. For additional information, refer to Note 8. Borrowings to our Consolidated Financial Statements.

On February 24, 2020, we announced that our Board of Directors had authorized a share repurchase program of up to $100 million of our common stock. On April 28, 2022, we announced that our Board of Directors had increased the authorization by up to $150 million in additional aggregate value. The timing and amount of any shares repurchased will be determined by us based on our evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. We are not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of our common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock. During the three months ended March 31, 2023 and 2022, we repurchased 433,759 shares and 313,395 shares of common stock, respectively, for a total of $7.5 million and $6.8 million, respectively.

Cash flows from operating, investing, and financing activities as reflected in our Consolidated Statements of Cash Flows are summarized in the following table:

	Three Months Ended March 31,
(in millions)	2023		2022
Net cash flows provided by (used in):
Operating activities	$	21.9	$	0.8
Investing activities	(3.9)		(6.8)
Financing activities	(14.3)		(12.0)
Effect of exchange rate changes on cash and cash equivalents	0.1		(0.2)
Net increase (decrease) in cash and cash equivalents	$	3.8	$	(18.2)

27

Operating Activities

Cash provided by operating activities adjusts net earnings for certain non-cash items, including depreciation expense, amortization of intangible assets, stock-based compensation, changes in deferred income taxes, and the effects of changes in operating assets and liabilities. The increase in cash provided by operating activities in the first quarter of 2023 as compared to the first quarter of 2022 was primarily due to the favorable changes in working capital and incentive compensation payments, partially offset by lower net earnings. The favorable changes in working capital in 2023 were primarily driven by an increase in accounts payable and a decrease in accounts receivable, partially offset by an increase in inventories related to last time buy requirements as we transition our products into new technology platforms.

Investing Activities

The cash used in investing activities during 2023 and 2022 was primarily driven by capital expenditures to support product innovation and cost savings.

In 2023, we expect capital expenditures to be in the range of 4% to 5% of revenues.

Financing Activities

Cash used in financing activities during 2023 was primarily related to the $7.5 million of repurchases of common stock, the $6.0 million payment of taxes related to net share settlement of equity awards, and the $1.6 million payment of debt issuance costs, partially offset by proceeds of $1.4 million from the exercise of options. Cash used in financing activities during 2022 was primarily related to the $6.8 million of repurchases of common stock and the $6.1 million payment of taxes related to net share settlement of equity awards, partially offset by proceeds of $3.9 million from the exercise of options.

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, 2022 filed with the Securities and Exchange Commission on February 9, 2023. There are no material changes in our previously reported critical accounting estimates.

Recent Accounting Standards

As included in Note 2. Recent Accounting Standards to our Consolidated Financial Statements, there are no recently issued or adopted accounting standards that have had or are not expected to have a significant impact on our revenue, earnings, or liquidity.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

During the three months ended March 31, 2023, 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, 2022. For a discussion of our exposure to market risk as of December 31, 2022, 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, 2022.

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 first quarter of 2023 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.

Issuer Purchases of Equity Securities

On February 24, 2020, the Company announced that its Board of Directors had authorized a share repurchase program of up to $100 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 million in additional aggregate value. The timing and amount of any shares repurchased will be determined by the Company based on its evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. The Company is not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of the Company’s common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock.

Below is a summary of share repurchases for the three months ended March 31, 2023:
