1. Basis of Presentation

Description of Business - 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, 2021 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, including considerations for the impact of the COVID-19 pandemic on the macroeconomic environment. The situation related to the COVID-19 pandemic continues to be complex and dynamic. The Company cannot reasonably estimate the duration of the COVID-19 pandemic or fully ascertain its impact on the Company’s future results and market capitalization, which could adversely impact estimates such as the recoverability of goodwill and long-lived assets and the realizability of deferred tax assets. 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, 2022, the Company repurchased 313,395 shares of common stock for a total of $6.8 million. The Company did not repurchase any shares of its common stock during the three months ended March 31, 2021.

Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at March 31, 2022 and 2021 were $3.2 million and $2.5 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.

2. Recent Accounting Standards

Recently Adopted Accounting Standards

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06 to simplify the accounting for certain financial instruments with characteristics of liabilities and equity. The standard eliminates certain accounting models that separated embedded conversion features from host contracts for convertible instruments, requiring bifurcation only if the convertible feature qualifies as a derivative under Accounting Standards Codification ("ASC") 815 or for convertible instruments issued at a substantial premium. In addition, the guidance requires the if-converted method of calculating diluted earnings per share for convertible instruments, which eliminates the use of the treasury stock method for instruments that may be settled in cash or shares. The standard can be adopted on a modified retrospective basis to transactions outstanding as of the adoption date or on a fully retrospective basis to all periods presented. The Company adopted the standard using the modified retrospective method on January 1, 2022. Adoption of the standard did not impact the Consolidated Financial Statements as all of the Company’s convertible instruments were settled prior to the adoption date. See Note 8. Borrowings for detail on the Company's convertible instruments that matured on November 1, 2021.

3. Acquisition

On May 3, 2021, the Company acquired all of the outstanding shares of common stock of Integrated Microwave Corporation ("IMC") for $81.4 million. During the three months ended March 31, 2022, the Company recorded a purchase price adjustment of $0.7 million that will be paid in the second quarter of 2022 and is recorded in the Other accrued expenses line on the Consolidated Balance Sheets. The adjustment, which did not impact the Consolidated Statements of Earnings, resulted in an increase to goodwill of $0.7 million. The acquired business provides RF filters to the defense, industrial, and communications markets. The transaction was accounted for under the acquisition method of accounting and the results of operations are included in the Consolidated Financial Statements from the date of acquisition in the Precision Devices ("PD") segment.

The table below represents the final allocation of the purchase price to net assets acquired as of May 3, 2021:

(in millions)
Cash	$	2.2
Receivables	3.0
Inventories	2.6
Property, plant, and equipment	8.3
Customer relationships	27.7
Developed technology	5.2
Trademarks and other amortized intangible assets	1.6
Goodwill	32.0
Assumed current liabilities	(1.2)
Total purchase price	$	81.4

The fair value for customer relationships was determined using the multi-period excess earnings method under the income approach. This method reflects the present value of expected future cash flows less charges representing the contribution of other assets to those cash flows. The fair value for developed technology was determined using the relief from royalty method under the income approach. The fair value measurements of intangible assets are based on significant unobservable inputs, and thus represent Level 3 inputs. Significant assumptions used in assessing the fair values of customer relationships and developed technology include forecasted revenue growth rates, profit margins, customer attrition rates, royalty rates, and discount rates. Discount rates of 13.0% and 14.0% were applied to the expected future cash flows to reflect the risk related to customer relationships and developed technology, respectively. Customer relationships and developed technology will be amortized on a straight-line basis over estimated useful lives of 8 years and 10 years, respectively.

The excess of the total purchase price over the total fair value of the identifiable assets and liabilities was recorded as goodwill. The goodwill recognized is primarily attributable to synergies and the assembled workforce. All of the goodwill resulting from this acquisition is tax deductible. Goodwill has been allocated to the PD segment, which is the segment expected to benefit from the acquisition.

Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

The Company believes the fair values assigned to intangible assets are based on reasonable assumptions and estimates that approximate the amounts a market participant would pay for these intangible assets as of the acquisition date. Actual results could differ materially from these estimates.

Pro-forma financial information has not been provided as the acquisition did not have a material impact on the Consolidated Statements of Earnings.

The gross carrying value and accumulated amortization for each major class of intangible assets are as follows:

	March 31, 2022				December 31, 2021
(in millions)	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Amortized intangible assets:
Trademarks	$	2.0	$	0.7	$	2.0	$	0.6

2023	11.6
2024	11.6

7. Restructuring and Related Activities

Restructuring and related activities are designed to better align the Company's operations with current market conditions through headcount reductions, targeted facility consolidations, and other measures to further optimize operations and align resources with growth opportunities.

During the three months ended March 31, 2022, the Company restructured its MEMS Microphones product line, which is included within the Audio segment. This action resulted in the termination of a research and development project and a reduction in workforce. During the three months ended March 31, 2022, the Company recorded restructuring charges of $5.4 million related to this action, including $4.2 million in contract termination costs and $1.2 million in severance pay and benefits. The Company may incur additional restructuring charges of up to $4 million during the remainder of the fiscal year for certain fixed assets of the terminated project, which cannot be reasonably estimated at this time due to the complex nature of the assets under review for use in other projects.

In addition, during the three months ended March 31, 2022, the Company recorded restructuring charges of $1.2 million for severance pay and benefits to rationalize the Intelligent Audio product line workforce, which is included within the Audio segment.

No restructuring charges were recorded within Gross profit for the three months ended March 31, 2022. During the three months ended March 31, 2022, the Company recorded total restructuring charges within Operating expenses of $6.6 million, primarily for contract termination costs and severance pay and benefits associated with the MEMS Microphones product line and other actions to rationalize the Intelligent Audio product line workforce.

No restructuring charges were recorded within Gross profit for the three months ended March 31, 2021. During the three months ended March 31, 2021, the Company recorded restructuring charges within Operating expenses of $0.2 million for severance pay and benefits.

On September 4, 2020, the Company entered into a new Credit Agreement (the "New Credit Agreement"). The New Credit Agreement provides for a senior secured revolving credit facility (the "New Credit Facility") with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. The New Credit Agreement serves as refinancing of indebtedness and terminates the Company's Revolving Credit Facility Agreement dated as of October 11, 2017 ("Prior Credit Facility"). The Prior Credit Facility consisted of a $400.0 million senior secured revolving credit facility.

At any time during the term of the New Credit Facility, the Company will be permitted to increase the commitments under the New 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 New Credit Facility will terminate, and loans outstanding thereunder will mature, on January 2, 2024.

The New Credit Agreement includes requirements, to be tested quarterly, that the Company maintains (i) a minimum ratio of Consolidated EBITDA to consolidated interest expense of 3.25 to 1.0 (the "Interest Coverage Ratio"), (ii) a maximum ratio of Consolidated total indebtedness to Consolidated EBITDA of 3.75 to 1.0 (the "Total Leverage Ratio"), and (iii) a maximum ratio of senior secured indebtedness to Consolidated EBITDA of 3.25 to 1.0 (the "Senior Secured 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 New Credit Agreement. At March 31, 2022, 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 New Credit Facility will be, at the Borrowers' option (1) LIBOR (or EURIBOR for borrowings denominated in Euro; or SONIA for borrowings denominated in Pounds Sterling) plus the rates per annum determined from time to time based on the total 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 New Credit Agreement) plus the Applicable Margin. The Applicable Margin for LIBOR could range from 1.50% to 2.50% while the Applicable Margin for ABR could range from 0.50% to 1.50%. Prior to the discontinuation of the relevant LIBOR reference rate on June 30, 2023, the Company and its lenders will agree on an ABR to address the replacement of LIBOR for the remaining life of the New Credit Facility.

The interest rate under the New Credit Facility is variable based on LIBOR at the time of the borrowing and the Applicable Margin. In addition, a commitment fee accrues on the average daily unused portion of the New Credit Facility at a rate of 0.225% to 0.375%.

The weighted-average interest rate on the Company's borrowings under the New Credit Facility was 2.12% for the three months ended March 31, 2022. There were no borrowings outstanding under the New Credit Facility during the three months ended March 31, 2021. The weighted-average commitment fee on the revolving lines of credit was 0.24% and 0.27% for the three months ended March 31, 2022 and 2021, respectively.

3.25% Convertible Senior Notes Due November 1, 2021

In May 2016, the Company issued $172.5 million aggregate principal amount of 3.25% convertible senior notes which matured on November 1, 2021 (the “Notes”). Interest was payable semiannually in arrears on May 1 and November 1 of each year. The Notes were governed by an Indenture between the Company, as issuer, and U.S. Bank National Association as trustee. Upon conversion, the Company could elect to pay or deliver cash, shares of the Company's common stock, or a combination of cash and shares of common stock. On November 1, 2021, the Company settled the principal amount of the Notes in cash and the excess conversion value by delivering 0.4 million shares of its common stock held in treasury. The conversion rate was 54.2741 shares of common stock per $1,000 principal amount of Notes. The conversion price was $18.4250 per share of common stock. The Notes were senior unsecured obligations.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that did not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the Notes as a whole. The excess of the principal amount of the liability component over its carrying amount was amortized to interest expense over the term of the Notes.

The following table sets forth total interest expense recognized related to the Notes:

	Three Months Ended
(in millions)	March 31, 2021
3.25% coupon	$	1.4
Amortization of debt issuance costs	0.3
Amortization of debt discount	1.9
Total	$	3.6

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.

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, 2022 and 2021 was a 13.8% provision (inclusive of discrete items totaling $1.0 million of benefit) and a 17.8% provision (inclusive of discrete items totaling $0.1 million of benefit), respectively. The discrete items impacting the tax provision for the three months ended March 31, 2022 were primarily attributable to the stock-based compensation deduction. Absent the discrete items, the ETR for the three months ended March 31, 2022 and 2021 was an 18.6% provision and an 18.4% provision, 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 three months ended March 31, 2022 and 2021.

The Company's ETR is favorably impacted by tax holidays granted to the Company in Malaysia and China. The Company secured the Chinese tax holiday in the first quarter of 2022. These tax holidays are subject to the Company's annual satisfaction of certain conditions, including investment and sales thresholds. If the Company fails to satisfy such conditions, the Company's ETR may be significantly adversely impacted. The benefit of the tax holidays in Malaysia and China for the three months ended March 31, 2022 was approximately $2.6 million, or $0.03 on a basic per share basis. The benefit of these incentives for the three months ended March 31, 2021 was approximately $2.4 million, or $0.03 on a basic per share basis. The Company's existing significant tax holiday in Malaysia will expire on December 31, 2026, while the tax holiday in China will expire on December 31, 2023.

11. Equity Incentive Program

Stock-based compensation expense recognized in the Consolidated Statements of Earnings totaled $7.6 million and $11.1 million for the three months ended March 31, 2022 and 2021, respectively. The tax benefit recognized related to stock-based compensation expense was $3.2 million for the three months ended March 31, 2022. No tax benefit was recognized related to stock-based compensation expense for the three months ended March 31, 2021.

Stock Options and SSARs

The expense related to stock options granted in the three months ended March 31, 2022 and 2021 was estimated on the date of grant using a Black-Scholes option-pricing model based on the assumptions shown in the table below:

	Three Months Ended March 31,
	2022	2021
Risk-free interest rate	0.85%	0.06%
Dividend yield	—%	—%
Expected life (years)	4.5	4.5
Volatility	34.3%	36.0%
Fair value at date of grant	$6.29	$6.14

There was no unrecognized compensation expense related to SSARs at March 31, 2022. At March 31, 2022, unrecognized compensation expense related to stock options not yet exercisable of $2.9 million is expected to be recognized over a weighted-average period of 1.8 years.

RSUs

The following table summarizes the Company's restricted stock unit ("RSU") activity for the three months ended March 31, 2022:

	Share units	Weighted-average grant date fair value
Unvested at December 31, 2021	1,778,639	$	18.89
Granted	997,294	21.14
Vested (1)	(722,073)	17.98
Forfeited	(65,911)	19.50
Unvested at March 31, 2022	1,987,949	$	20.28

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

At March 31, 2022, $32.6 million of unrecognized compensation expense related to RSUs is expected to be recognized over a weighted-average period of 2.2 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 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 COVID-19 pandemic brought on unique and unprecedented challenges to the Company, particularly in the hearing health and medtech markets. Many of the Company's executive compensation programs were affected, including outstanding PSU awards. Due to the impact of the COVID-19 pandemic on the Company’s overall business performance, effective February 8, 2021, the Company’s Compensation Committee approved certain modifications to PSUs granted in February 2018, 2019, and 2020.

For the awards granted in February 2018 (the “2018 PSUs”), the number of PSUs that may be earned and vest was originally based on the Company’s revenues and stock price performance over a three-year performance period. The modified award was based on the Company’s revenues and stock price performance over three separate one-year performance periods to isolate the impact of the COVID-19 pandemic on the Company's fiscal 2020 performance. In addition, the performance periods corresponding to fiscal 2018 and 2019 were weighted at 25% each while the performance period corresponding to fiscal 2020 was weighted at 50%, given the impact of fiscal 2020 performance on shareholders. Service conditions were not modified. The modification of the 2018 PSUs affected nine employees and resulted in total incremental compensation expense of $3.9 million, which was recognized in the first quarter of 2021 as there was no remaining service period. In February 2021, the 2018 PSUs were converted from 329,092 PSUs to 190,544 shares of common stock based on achievement of the modified conditions.

For the awards granted in February 2019 (the “2019 PSUs”), the number of PSUs that may be earned and vest was originally based on the Company's revenues and TSR relative to the component companies of the S&P Semiconductor Select Industry Index over a three-year performance period. The modified award was based on the Company’s revenues and TSR relative to the component companies of the S&P Semiconductor Select Industry Index over three separate one-year performance periods to isolate the impact of the COVID-19 pandemic on the Company's fiscal 2020 performance. Each period was weighted equally, as the Company expected to face challenges related to the COVID-19 pandemic in fiscal 2021. Service conditions were not modified. The modification of the 2019 PSUs affected eight employees and resulted in total incremental compensation expense of $2.4 million, which was recognized over the remaining service period. Incremental compensation expense was subject to adjustment for the achievement of the performance condition based on fiscal 2021 revenues. In February 2022, the 2019 PSUs were converted from 227,812 PSUs to 150,811 shares of common stock based on achievement of the modified conditions.

For the awards granted in February 2020 (the “2020 PSUs”), the number of PSUs that may be earned and vest was originally based on TSR relative to the component companies of the S&P Semiconductor Select Industry Index over a three-year performance period. The modified award replaces the S&P Semiconductor Select Industry Index with the Russell 2000 Index. The Company is a member of the Russell 2000 Index, which represents a broader, more diversified index that better aligns with the Company's strategy. Service conditions were not modified. The modification of the 2020 PSUs affected eight employees and resulted in total incremental compensation expense of $4.7 million, which will be recognized over the remaining service period.

The following table summarizes the Company's PSU activity for the three months ended March 31, 2022:

	Share units	Weighted-average grant date fair value
Unvested at December 31, 2021	766,466	$	21.28
Granted	294,935	29.92
Vested (1)	(227,812)	18.44
Forfeited	—	—
Unvested at March 31, 2022	833,589	$	25.12

(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, 2022, $16.5 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)	2022		2021
Net earnings	$	18.1	$	12.5
Basic:
Net earnings per share	$	0.20	$	0.14
Weighted-average shares outstanding	92.3		92.3
Diluted:
Net earnings per share	$	0.19	$	0.13
Weighted-average shares outstanding	94.3		95.0

The Company intended to settle the principal amount of the Notes in cash during all periods preceding settlement. The treasury stock method was used to calculate the dilutive effect of the conversion option on diluted earnings per share, if applicable. For the three months ended March 31, 2022 and 2021, the weighted-average number of anti-dilutive potential common shares for stock-based awards excluded from the diluted earnings per share calculation above was 0.5 million and 1.8 million, respectively.

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, 2022 and December 31, 2021.

RF solutions are also used in mmWave 5G communications equipment. PD has sales, support, and engineering facilities in North America, Europe, and Asia as well as manufacturing facilities in North America and Asia.

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

IMC Acquisition

On May 3, 2021, we acquired all of the outstanding shares of common stock of Integrated Microwave Corporation ("IMC") for $81.4 million. The acquired business provides RF filters to the defense, industrial, and communications markets. The acquisition's operations are included in the PD segment. For additional information, refer to Note 3. Acquisition to our Consolidated Financial Statements.

COVID-19 Update

The COVID-19 pandemic, particularly as it relates to the emergence of new variants of the virus, continues to have widespread, rapidly-evolving, and unpredictable impacts in the U.S. and international markets. Many countries have continued applying containment and mitigation measures, resulting in global business disruption. These measures have impacted our business operations, results of operations, customer demand, and the productivity of our facilities, particularly in China, Malaysia, and the Philippines.

The resurgence of COVID-19 in China and the related lockdowns has had, and may continue to have, an impact on various aspects of our business. During the first quarter of 2022, demand for some of our products, particularly in our MEMS Microphones product line, was negatively impacted. While we did not experience a similar impact on demand with respect to our hearing health products or in our PD segment, new or prolonged lockdowns may result in an adverse impact on demand across more of our product lines. In addition, while our facilities in China have generally remained operational during the resurgence, we may experience facility closures or increased employee absenteeism if there is continued spread of COVID-19 variants. We also continue to manage the ongoing impacts of the supply chain challenges that are impacting many industries, and have been exacerbated by the lockdowns in China, causing shipping and logistics challenges, and limiting component supplies.

The situation related to COVID-19 continues to be complex and dynamic. We cannot reasonably estimate the duration of the pandemic or fully ascertain its impact to our future results. As the COVID-19 pandemic evolves, we will continue to actively monitor developments and business conditions and may take actions that alter business operations as may be required by applicable authorities or that we determine are in the best interests of our employees, customers, suppliers, stockholders, and communities. It is not clear what potential effects any such alterations or modifications may have on our business, including the effects on our financial results. For additional information regarding risks related to COVID-19, please see Item 1A, Risk Factors, in the Annual Report on Form 10-K for the year ended December 31, 2021.

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.

Results of Operations for the Three Months Ended March 31, 2022 compared with the Three Months Ended March 31, 2021

	Three Months Ended March 31,
(in millions, except per share amounts)	2022		2021
Revenues	$	201.4	$	201.0

Revenues

Revenues for the first quarter of 2022 were $201.4 million, compared with $201.0 million for the first quarter of 2021, an increase of $0.4 million or 0.2%. PD revenues increased $17.8 million, primarily due to our acquisition of IMC and organic growth from the defense, industrial, medtech, and communications markets. Audio revenues decreased $17.4 million, primarily due to lower demand for MEMS microphones in the computing and mobile markets. The computing market demand was higher in the previous period driven by work-from-home and remote-learning trends. The decrease in mobile market revenue was driven by our shift away from commoditized products, weakening demand in China during the first quarter of 2022, and a challenging supply chain. The lower demand for MEMS microphones was partially offset by share gains and market growth in the hearing health market. Audio revenues were also impacted by lower average pricing on mature products.

Cost of Goods Sold

Cost of goods sold ("COGS") for the first quarter of 2022 was $118.1 million, compared with $123.0 million for the first quarter of 2021, a decrease of $4.9 million or 4.0%. This decrease was primarily due to favorable mix and product cost reductions, partially offset by lower factory capacity utilization and higher precious metal costs.

Gross Profit and Non-GAAP Gross Profit

Gross profit for the first quarter of 2022 was $83.3 million, compared with $78.0 million for the first quarter of 2021, an increase of $5.3 million or 6.8%. Gross profit margin (gross profit as a percentage of revenues) for the first quarter of 2022 was 41.4%, compared with 38.8% for the first quarter of 2021. The increases were primarily due to favorable mix and product cost reductions, partially offset by lower factory capacity utilization and higher precious metal costs.

Non-GAAP gross profit for the first quarter of 2022 was $83.8 million, compared with $78.4 million for the first quarter of 2021, an increase of $5.4 million or 6.9%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the first quarter of 2022 was 41.6%, compared with 39.0% for the first quarter of 2021. The increases were primarily due to favorable mix and product cost reductions, partially offset by lower factory capacity utilization and higher precious metal costs.

20

Research and Development Expenses

Research and development expenses for the first quarter of 2022 were $23.1 million, compared with $23.3 million for the first quarter of 2021, a decrease of $0.2 million or 0.9%. Research and development expenses as a percentage of revenues for the first quarter of 2022 and 2021 were 11.5% and 11.6%, respectively. Our overall expenses have remained consistent, however we have rationalized our spending in our MEMS Microphones product line and reduced development activities in our Intelligent Audio product line, which were partially offset by increased development activities in our precision devices and hearing health product lines. Expenses as a percentage of revenues were consistent with the prior year as spending and revenues have remained consistent.

Selling and Administrative Expenses

Selling and administrative expenses for the first quarter of 2022 were $32.3 million, compared with $36.2 million for the first quarter of 2021, a decrease of $3.9 million or 10.8%. Selling and administrative expenses as a percentage of revenues for the first quarter of 2022 and 2021 were 16.0% and 18.0%, respectively. The decrease in expenses was primarily driven by stock-based compensation. For additional information on stock-based compensation, refer to Note 11. Equity Incentive Program to our Consolidated Financial Statements. Legal expenses were also lower due to reduced activity related to the protection of our intellectual property. These decreases were partially offset by the normal operational expenses related to our IMC acquisition. The decrease in expenses as a percentage of revenues was driven by our lower spending as revenues have remained consistent.

Restructuring Charges

During the first quarter of 2022, we restructured our MEMS Microphones product line, which is included within the Audio 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. We may incur additional restructuring charges of up to $4 million during the remainder of the fiscal year for certain fixed assets of the terminated project, which cannot be reasonably estimated at this time due to the complex nature of the assets under review for use in other projects. In addition, we recorded restructuring charges of $1.2 million to rationalize the Intelligent Audio product line workforce, which is also included within the Audio segment. For additional information, refer to Note 7. Restructuring and Related Activities to our Consolidated Financial Statements.

During the first quarter of 2021, we recorded restructuring charges of $0.2 million within Operating expenses related to a reduction in workforce.

Interest Expense, net

Interest expense for the first quarter of 2022 was $0.8 million, compared to $4.0 million for the first quarter of 2021, a decrease of $3.2 million. The decrease was primarily due to lower outstanding borrowings. For additional information on borrowings and interest expense, refer to Note 8. Borrowings to our Consolidated Financial Statements.

Other Income, net

Other income for the first quarter of 2022 was $0.5 million, compared with income of $0.9 million for the first quarter of 2021, a change of $0.4 million. The change is primarily due to the depreciation of our investment balances, partially offset by favorable impacts from foreign currency exchange rate changes.

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

The effective tax rate ("ETR") for the first quarter of 2022 and 2021 was a 13.8% provision (inclusive of discrete items totaling $1.0 million of benefit) and a 17.8% provision (inclusive of discrete items totaling $0.1 million of benefit), respectively. The discrete items impacting the first quarter of 2022 tax provision are primarily attributable to the stock-based compensation deduction. Absent the discrete items, the ETR for the first quarter of 2022 and 2021 was an 18.6% provision and an 18.4% provision, 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 both the first quarter of 2022 and 2021. The change in the ETR was due to the mix of earnings and losses by taxing jurisdictions and net discrete items.

21

The non-GAAP ETR for the first quarter of 2022 was a 13.0% provision, compared with a 13.7% provision for the first quarter of 2021. The change in the non-GAAP ETR was due to the mix of earnings and losses by taxing jurisdictions.

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 well as the favorable impact of our tax holidays in Malaysia and China. A significant portion of our pre-tax income is subject to a lower tax rate as a result of our Malaysian and Chinese tax holidays, subject to our annual satisfaction of certain conditions we expect to continue to satisfy through the holiday period. Our existing significant tax holiday in Malaysia will expire on December 31, 2026, while our tax holiday in China will expire on December 31, 2023. For additional information on these tax holidays, refer to Note 10. Income Taxes to our Consolidated Financial Statements.

Net Earnings

Net earnings for the first quarter of 2022 was $18.1 million, compared with earnings of $12.5 million for the first quarter of 2021, an increase of $5.6 million. As described above, the increase is primarily due to higher gross profit, lower stock-based compensation, and a decrease in interest expense, partially offset by higher restructuring charges.

Earnings and Adjusted Earnings Before Interest and Income Taxes

Earnings before interest and income taxes ("EBIT") for the first quarter of 2022 was $21.8 million, compared with $19.2 million for the first quarter of 2021, an increase of $2.6 million. EBIT margin (EBIT as a percentage of revenues) for the first quarter of 2022 was 10.8%, compared with 9.6% for the first quarter of 2021. The increases in EBIT and EBIT margin were primarily due to higher gross profit margin and lower stock-based compensation, partially offset by higher restructuring charges.

Adjusted earnings before interest and income taxes ("Adjusted EBIT") for the first quarter of 2022 was $39.4 million, compared with $34.3 million for the first quarter of 2021, an increase of $5.1 million. Adjusted EBIT margin (adjusted EBIT as a percentage of revenues) for the first quarter of 2022 was 19.6%, compared with 17.1% for the first quarter of 2021. The increases in Adjusted EBIT and Adjusted EBIT margin were primarily due to higher non-GAAP gross profit margin.

Diluted Earnings per Share and Non-GAAP Diluted Earnings per Share

Diluted earnings per share was $0.19 for the first quarter of 2022, compared with earnings of $0.13 for the first quarter of 2021, an increase of $0.06. As described above, the increase was primarily due to higher gross profit and lower stock-based compensation, partially offset by higher restructuring charges.

Non-GAAP diluted earnings per share was $0.35 for the first quarter of 2022, compared with earnings of $0.29 for the first quarter of 2021, an increase of $0.06. As described above, the increase was primarily due to higher non-GAAP gross profit.

(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)    Under GAAP in effect for the Company through 2021, certain convertible debt instruments that may be settled in cash (or other assets) upon conversion were required to be separately accounted for as liability (debt) and equity (conversion option) components of the instrument in a manner that reflected the issuer’s nonconvertible debt borrowing rate. Accordingly, for GAAP purposes we were required to recognize imputed interest expense on the Company’s $172.5 million of convertible senior notes due November 1, 2021 that were issued in a private placement in May 2016. The imputed interest rate for the convertible notes was 8.12%, while the actual coupon interest rate of the notes was 3.25%. The difference between the imputed interest expense and the coupon interest expense was excluded from management’s assessment of the Company’s operating performance because management believes that this non-cash expense was not indicative of its core, ongoing operating performance.

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

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

(6)    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. In addition, the Company entered into convertible note hedge transactions that expired upon maturity of the convertible notes to offset any potential dilution from the convertible notes. Although the anti-dilutive impact of the convertible note hedges was not reflected under GAAP, the Company included the anti-dilutive impact of the convertible note hedges in non-GAAP diluted average shares outstanding, if applicable.

Revenues

Revenues were $145.7 million for the first quarter of 2022, compared with $163.1 million for the first quarter of 2021, a decrease of $17.4 million or 10.7%. Revenues decreased primarily due to lower demand for MEMS microphones in the computing and mobile markets. The computing market demand was higher in the previous period driven by work-from-home and remote-learning trends. The decrease in mobile market revenue was driven by our shift away from commoditized products, weakening demand in China during the first quarter of 2022, and a challenging supply chain. The lower demand for MEMS microphones was partially offset by share gains and market growth in the hearing health market. Audio revenues were also impacted by lower average pricing on mature products.

Earnings and Adjusted Earnings Before Interest and Income Taxes

Audio EBIT was $22.2 million for the first quarter of 2022, compared with $30.4 million for the first quarter of 2021, a decrease of $8.2 million. EBIT margin for the first quarter of 2022 was 15.2%, compared to 18.6% for the first quarter of 2021. The decreases were primarily due to lower revenues and higher restructuring charges, partially offset by lower operating expenses, a reduction in legal expenses, lower amortization expense, and higher gross profit margin. The higher gross profit margin was driven by favorable mix and product cost reductions, partially offset by lower factory capacity utilization and lower average pricing on mature products.

Audio Adjusted EBIT was $33.3 million for the first quarter of 2022, compared with $36.9 million for the first quarter of 2021, a decrease of $3.6 million. Adjusted EBIT margin for the first quarter of 2022 was 22.9%, compared to 22.6% for the first quarter of 2021. The decreases were primarily due to lower revenues, partially offset by lower operating expenses, a reduction in legal expenses, and higher gross profit margin. The higher gross profit margin was driven by favorable mix and product cost reductions, partially offset by lower factory capacity utilization and lower average pricing on mature products.

Revenues

Revenues were $55.7 million for the first quarter of 2022, compared with $37.9 million for the first quarter of 2021, an increase of $17.8 million or 47.0%. Revenues increased primarily due to our acquisition of IMC and organic growth from the defense, industrial, medtech, and communications markets.

Earnings and Adjusted Earnings Before Interest and Income Taxes

PD EBIT was $12.3 million for the first quarter of 2022, compared with $4.5 million for the first quarter of 2021, an increase of $7.8 million. EBIT margin for the first quarter of 2022 was 22.1%, compared to 11.9% for the first quarter of 2021. The increases were primarily due to higher revenues, higher gross profit margin, and contributions from our acquisition of IMC, partially offset by an increase in intangible amortization. The gross profit margin increase was driven by favorable mix, product cost reductions, and an increase in average selling prices, partially offset by higher precious metal costs.

PD Adjusted EBIT was $14.5 million for the first quarter of 2022, compared with $5.8 million for the first quarter of 2021, an increase of $8.7 million. Adjusted EBIT margin for the first quarter of 2022 was 26.0%, compared with 15.3% for the first quarter of 2021. The increases were primarily due to higher revenues, higher gross profit margin, and contributions from our acquisition of IMC. The gross profit margin increase was driven by favorable mix, product cost reductions, and an increase in average selling prices, partially offset by higher precious metal costs.

Liquidity and Capital Resources

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

Due to the global nature of our operations, a significant portion of our cash is generated and typically held outside the United States. Our cash and cash equivalents totaled $50.7 million and $68.9 million at March 31, 2022 and December 31, 2021, respectively. Of these amounts, cash held by our non-U.S. operations totaled $45.6 million and $64.9 million as of March 31, 2022 and December 31, 2021, 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 May 3, 2021, we acquired all of the outstanding shares of common stock of IMC for $81.4 million. The acquired business provides RF filters to the defense, industrial, and communications markets. The acquisition's operations are included in the PD segment. For additional information, refer to Note 3. Acquisition to our Consolidated Financial Statements.

On September 4, 2020, we entered into a new Credit Agreement (the "New Credit Agreement"), which provides for a senior secured revolving credit facility (the "New Credit Facility") with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. As of March 31, 2022, outstanding borrowings under the New Credit Facility were $70.0 million. At any time during the term of the New Credit Facility, we will be permitted to increase the commitments under the New 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 New Credit Facility will terminate, and loans outstanding thereunder will mature, on January 2, 2024. 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, 2022, we repurchased 313,395 shares of common stock for a total of $6.8 million. We did not repurchase any shares of our common stock during the three months ended March 31, 2021.

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)	2022		2021
Net cash flows provided by (used in):
Operating activities	$	0.8	$	39.7
Investing activities	(6.8)		(7.0)

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 decrease in cash provided by operating activities for 2022 as compared to 2021 was primarily due to the unfavorable changes in working capital. The unfavorable changes in working capital in 2022 were primarily driven by the timing of sales and cash collections, an increase in procurement activity to mitigate supply chain risks, and the timing of payments. In addition, incentive compensation payments were larger in 2022 when compared to 2021. These unfavorable changes in working capital were partially offset by an increase in net earnings in 2022 as compared to 2021.

Investing Activities

The cash used in investing activities during 2022 and 2021 was primarily driven by capital expenditures to support product innovation and cost savings.

In 2022, we expect capital expenditures to be in the range of 4% to 6% of revenues.

Financing Activities

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. Cash provided by financing activities during 2021 was primarily related to the proceeds of $8.4 million from the exercise of options, partially offset by the $6.6 million payment of taxes related to net share settlement of equity awards.

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, 2021 filed with the Securities and Exchange Commission on February 9, 2022. There are no material changes in our previously reported critical accounting estimates.

Recent Accounting Standards

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

During the three months ended March 31, 2022, 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, 2021. For a discussion of our exposure to market risk as of December 31, 2021, 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, 2021.

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 2022 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.

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

Issuer Purchases of Equity Securities

On February 24, 2020, the Company announced that its Board of Directors had authorized a share repurchase program of up to $100 million of the Company's common stock. 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, 2022:

(in millions, except share and per share amounts)
Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Program	Approximate Dollar Value of Shares That May Yet Be Purchased Under The Program
January 2022	248,694	$	21.78	248,694	$	33.8
March 2022	64,701	$	21.00	64,701	$	32.5
Total Activity	313,395	$	21.62	313,395

On April 28, 2022, the Company announced that its Board of Directors had increased the authorization under the share repurchase program by up to $150 million in additional aggregate value.

Accounting Standards Update and Change in Accounting Principle [Abstract]

Recent Accounting Standards

Recently Adopted Accounting Standards

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06 to simplify the accounting for certain financial instruments with characteristics of liabilities and equity. The standard eliminates certain accounting models that separated embedded conversion features from host contracts for convertible instruments, requiring bifurcation only if the convertible feature qualifies as a derivative under Accounting Standards Codification ("ASC") 815 or for convertible instruments issued at a substantial premium. In addition, the guidance requires the if-converted method of calculating diluted earnings per share for convertible instruments, which eliminates the use of the treasury stock method for instruments that may be settled in cash or shares. The standard can be adopted on a modified retrospective basis to transactions outstanding as of the adoption date or on a fully retrospective basis to all periods presented. The Company adopted the standard using the modified retrospective method on January 1, 2022. Adoption of the standard did not impact the Consolidated Financial Statements as all of the Company’s convertible instruments were settled prior to the adoption date. See Note 8. Borrowings for detail on the Company's convertible instruments that matured on November 1, 2021.

Income Tax Disclosure [Abstract]

Income Tax Disclosure [Text Block]

The Company's ETR for the three months ended March 31, 2022 and 2021 was a 13.8% provision (inclusive of discrete items totaling $1.0 million of benefit) and a 17.8% provision (inclusive of discrete items totaling $0.1 million of benefit), respectively. The discrete items impacting the tax provision for the three months ended March 31, 2022 were primarily attributable to the stock-based compensation deduction. Absent the discrete items, the ETR for the three months ended March 31, 2022 and 2021 was an 18.6% provision and an 18.4% provision, 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 three months ended March 31, 2022 and 2021.

The Company's ETR is favorably impacted by tax holidays granted to the Company in Malaysia and China. The Company secured the Chinese tax holiday in the first quarter of 2022. These tax holidays are subject to the Company's annual satisfaction of certain conditions, including investment and sales thresholds. If the Company fails to satisfy such conditions, the Company's ETR may be significantly adversely impacted. The benefit of the tax holidays in Malaysia and China for the three months ended March 31, 2022 was approximately $2.6 million, or $0.03 on a basic per share basis. The benefit of these incentives for the three months ended March 31, 2021 was approximately $2.4 million, or $0.03 on a basic per share basis. The Company's existing significant tax holiday in Malaysia will expire on December 31, 2026, while the tax holiday in China will expire on December 31, 2023.

RSUs

The following table summarizes the Company's restricted stock unit ("RSU") activity for the three months ended March 31, 2022:

	Share units	Weighted-average grant date fair value
Unvested at December 31, 2021	1,778,639	$	18.89
Granted	997,294	21.14
Vested (1)	(722,073)	17.98
Forfeited	(65,911)	19.50
Unvested at March 31, 2022	1,987,949	$	20.28

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

At March 31, 2022, $32.6 million of unrecognized compensation expense related to RSUs is expected to be recognized over a weighted-average period of 2.2 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 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 COVID-19 pandemic brought on unique and unprecedented challenges to the Company, particularly in the hearing health and medtech markets. Many of the Company's executive compensation programs were affected, including outstanding PSU awards. Due to the impact of the COVID-19 pandemic on the Company’s overall business performance, effective February 8, 2021, the Company’s Compensation Committee approved certain modifications to PSUs granted in February 2018, 2019, and 2020.

For the awards granted in February 2018 (the “2018 PSUs”), the number of PSUs that may be earned and vest was originally based on the Company’s revenues and stock price performance over a three-year performance period. The modified award was based on the Company’s revenues and stock price performance over three separate one-year performance periods to isolate the impact of the COVID-19 pandemic on the Company's fiscal 2020 performance. In addition, the performance periods corresponding to fiscal 2018 and 2019 were weighted at 25% each while the performance period corresponding to fiscal 2020 was weighted at 50%, given the impact of fiscal 2020 performance on shareholders. Service conditions were not modified. The modification of the 2018 PSUs affected nine employees and resulted in total incremental compensation expense of $3.9 million, which was recognized in the first quarter of 2021 as there was no remaining service period. In February 2021, the 2018 PSUs were converted from 329,092 PSUs to 190,544 shares of common stock based on achievement of the modified conditions.

For the awards granted in February 2019 (the “2019 PSUs”), the number of PSUs that may be earned and vest was originally based on the Company's revenues and TSR relative to the component companies of the S&P Semiconductor Select Industry Index over a three-year performance period. The modified award was based on the Company’s revenues and TSR relative to the component companies of the S&P Semiconductor Select Industry Index over three separate one-year performance periods to isolate the impact of the COVID-19 pandemic on the Company's fiscal 2020 performance. Each period was weighted equally, as the Company expected to face challenges related to the COVID-19 pandemic in fiscal 2021. Service conditions were not modified. The modification of the 2019 PSUs affected eight employees and resulted in total incremental compensation expense of $2.4 million, which was recognized over the remaining service period. Incremental compensation expense was subject to adjustment for the achievement of the performance condition based on fiscal 2021 revenues. In February 2022, the 2019 PSUs were converted from 227,812 PSUs to 150,811 shares of common stock based on achievement of the modified conditions.

For the awards granted in February 2020 (the “2020 PSUs”), the number of PSUs that may be earned and vest was originally based on TSR relative to the component companies of the S&P Semiconductor Select Industry Index over a three-year performance period. The modified award replaces the S&P Semiconductor Select Industry Index with the Russell 2000 Index. The Company is a member of the Russell 2000 Index, which represents a broader, more diversified index that better aligns with the Company's strategy. Service conditions were not modified. The modification of the 2020 PSUs affected eight employees and resulted in total incremental compensation expense of $4.7 million, which will be recognized over the remaining service period.

The following table summarizes the Company's PSU activity for the three months ended March 31, 2022:

	Share units	Weighted-average grant date fair value
Unvested at December 31, 2021	766,466	$	21.28
Granted	294,935	29.92
Vested (1)	(227,812)	18.44
Forfeited	—	—
Unvested at March 31, 2022	833,589	$	25.12

(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, 2022, $16.5 million of unrecognized compensation expense related to PSUs is expected to be recognized over a weighted-average period of 1.9 years.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting Policy

Description of Business - 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, 2021 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, including considerations for the impact of the COVID-19 pandemic on the macroeconomic environment. The situation related to the COVID-19 pandemic continues to be complex and dynamic. The Company cannot reasonably estimate the duration of the COVID-19 pandemic or fully ascertain its impact on the Company’s future results and market capitalization, which could adversely impact estimates such as the recoverability of goodwill and long-lived assets and the realizability of deferred tax assets. 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, 2022, the Company repurchased 313,395 shares of common stock for a total of $6.8 million. The Company did not repurchase any shares of its common stock during the three months ended March 31, 2021.

Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at March 31, 2022 and 2021 were $3.2 million and $2.5 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.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Standards

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06 to simplify the accounting for certain financial instruments with characteristics of liabilities and equity. The standard eliminates certain accounting models that separated embedded conversion features from host contracts for convertible instruments, requiring bifurcation only if the convertible feature qualifies as a derivative under Accounting Standards Codification ("ASC") 815 or for convertible instruments issued at a substantial premium. In addition, the guidance requires the if-converted method of calculating diluted earnings per share for convertible instruments, which eliminates the use of the treasury stock method for instruments that may be settled in cash or shares. The standard can be adopted on a modified retrospective basis to transactions outstanding as of the adoption date or on a fully retrospective basis to all periods presented. The Company adopted the standard using the modified retrospective method on January 1, 2022. Adoption of the standard did not impact the Consolidated Financial Statements as all of the Company’s convertible instruments were settled prior to the adoption date. See Note 8. Borrowings for detail on the Company's convertible instruments that matured on November 1, 2021.
