Financial Statement Presentation -
The accompanying unaudited interim Consolidated Financial Statements have been 
prepared pursuant to the rules and regulations of the Securities and Exchange 
Commission ("SEC") for quarterly reports on Form 10-Q and do not include all 
of the information and note disclosures required by U.S. generally accepted 
accounting principles ("GAAP" or "U.S. GAAP") for complete financial 
statements. These unaudited interim Consolidated Financial Statements should 
therefore be read in conjunction with the Consolidated Financial Statements 
and Notes thereto for the year ended December 31, 2023 included in the 
Company's Annual Report on Form 10-K.
The accompanying unaudited interim Consolidated Financial Statements have been 
prepared in accordance with U.S. GAAP, which requires management to make 
estimates and assumptions that affect amounts reported in the Consolidated 
Financial Statements and accompanying disclosures. Although these estimates 
are based on management's best knowledge of current events and actions that 
the Company may undertake in the future, actual results may differ from those 
estimates. Management uses historical experience and all available information 
to make these estimates. The unaudited interim Consolidated Financial 
Statements reflect all adjustments of a normal, recurring nature that are, in 
the opinion of management, necessary for a fair statement of results for these 
interim periods.
Share Repurchase Program -
On February 24, 2020, the Company announced that its Board of Directors had 
authorized a share repurchase program of up to $
100.0
million of the Company's common stock. On April 28, 2022, the Company 
announced that its Board of Directors had increased the authorization by up to 
$
150.0
million in additional aggregate value. The timing and amount of any shares 
repurchased will be determined by the Company based on its evaluation of 
market conditions and other factors, and will be made in accordance with 
applicable securities laws in either the open market or in privately 
negotiated transactions. The Company is not obligated to purchase any shares 
under the program, and the program may be suspended or discontinued at any 
time. The actual timing, number, and share price of shares repurchased will 
depend on a number of factors, including the market price of the Company's 
common stock, general market and economic conditions, and applicable legal 
requirements. Any shares repurchased will be held as treasury stock. During 
the three months ended March 31, 2023, the Company repurchased
433,759
shares of common stock for a total of $
7.5
million. The Company did
not
repurchase any shares of its common stock during the three months ended March 
31, 2024.
Non-cash Investing Activities
- Purchases of property, plant, and equipment included in accounts payable at 
March 31, 2024 and 2023 were $
0.7
million and $
2.3
million, respectively. These non-cash amounts are not reflected as "Capital 
expenditures" within Investing Activities on the Consolidated Statements of 
Cash Flows for the respective periods.
Operating lease liabilities arising from obtaining right-of-use assets for the 
three months ended March 31, 2023 were $
1.1

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

assets acquired within the measurement period (not to exceed one year from the 
date of acquisition), including finalization of asset appraisals, the Company 
will refine its estimates of the purchase price allocation.

The following unaudited pro-forma summary presents consolidated financial 
information as if CD had been acquired on January 1, 2022. The unaudited 
pro-forma financial information is based on historical results of operations 
and financial positions of the Company and CD. The pro-forma earnings are 
adjusted to reflect the comparable impact of depreciation and amortization 
expense resulting from the fair value measurement of tangible and intangible 
assets, nonrecurring deal-related costs, employee retention, inventory step-up 
charges, and interest expense on borrowings to fund the acquisition.
The unaudited pro-forma financial information does not necessarily represent 
the results that would have occurred had the acquisition occurred on January 
1, 2022. In addition, the unaudited pro-forma information should not be deemed 
to be indicative of future results.

Revolving Credit Facility
On February 8, 2023, the Company entered into an Amended and Restated Credit 
Agreement (the "A&R Credit Agreement") that amends and restates the prior 
Credit Agreement, dated September 4, 2020, and provides for a senior secured 
revolving credit facility with borrowings in an aggregate principal amount at 
any time outstanding not to exceed $
400.0
million (the "Credit Facility"). The A&R Credit Agreement, among other things, 
extends the maturity date of the Credit Facility from January 2, 2024 to 
February 8, 2028, replaces the London Inter-Bank Offered Rate ("LIBOR") with 
the Term Secured Overnight Financing Rate ("Term SOFR") as a reference rate 
available for borrowings, amends the minimum Interest Coverage Ratio, and 
amends certain other financial covenants with which the Company must comply, 
as described below.
On September 25, 2023, the Company amended its A&R Credit Agreement to, among 
other things, (a) permit the Company in connection with the acquisition of CD, 
to incur senior priority seller financing indebtedness (the "Seller Note") in 
an aggregate principal amount of $
122.9
million secured by certain assets (including equity interests) acquired in 
connection with such acquisition and the capital stock of Cornell Dubilier, 
LLC (the "Acquisition Assets"), which shall mature two years after the 
effective date of such Seller Note (the "Seller Note Maturity Date"), (b) 
extends the requirement to pledge the Acquisition Assets that would otherwise 
constitute collateral under the Credit Agreement to the date that is 90 days 
after the Seller Note Maturity Date, and (c) restricts, until the Seller Note 
Maturity Date, the amount of dispositions and investments from the Company and 
certain of its subsidiaries into Cornell Dubilier, LLC and the acquired 
subsidiaries that constitute Acquisition Assets from exceeding $
80.0
million in the aggregate. All other terms remain the same as the A&R Credit 
Agreement dated February 8, 2023.
Up to $
100.0
million of the Credit Facility will be available in Euro, Pounds Sterling, and 
other currencies requested by the Company and up to $
50.0
million of the Credit Facility will be made available in the form of letters 
of credit. Undrawn amounts under the Credit Facility accrue a commitment fee 
at a per annum rate of
0.225
% to
0.350
%, based on a leverage ratio grid.
At any time during the term of the Credit Facility, the Company will be 
permitted to increase the commitments under the Credit Facility or to 
establish one or more incremental term loan facilities under the Credit 
Facility in an aggregate principal amount not to exceed the sum of $
200.0
million, plus additional amounts, so long as the senior secured leverage ratio 
does not exceed
2.00
to 1.00.
The A&R Credit Agreement includes requirements, to be tested quarterly, that 
the Company maintains (i) a minimum ratio of Consolidated EBITDA to 
consolidated cash interest expense of
3.00
to 1.00, (the "Interest Coverage Ratio"), (ii) a ratio of total indebtedness, 
minus netted cash in an aggregate amount not to exceed $50.0 million, to 
Consolidated EBITDA of
3.75
to 1.00 (the "Total Net Leverage Ratio"), and (iii) a maximum ratio of senior 
net secured indebtedness to Consolidated EBITDA of
3.25
to 1.00 (the "Senior Secured Net Leverage Ratio"). For these ratios, 
Consolidated EBITDA and consolidated interest expense are calculated using the 
most recent four consecutive fiscal quarters in a manner defined in the A&R 
Credit Agreement. At March 31, 2024, the Company was in compliance with these 
covenants and it expects to remain in compliance with all of its debt 
covenants over the next twelve months.
The interest rates under the Credit Facility will be, at the Borrowers' option 
(1) (A) in the case of borrowings denominated in U.S. dollars Term SOFR, (B) 
in the case of borrowings denominated in Sterling, Daily Simple Sonia, or (C) 
for borrowings denominated in Euro, EURIBOR, in each case, plus the rates per 
annum determined from time to time based on the total net leverage ratio of 
the Company as of the end of and for the most recent period of four fiscal 
quarters for which financial statements have been delivered (the "Applicable 
Margin"); or (2) in the case of borrowings denominated in U.S. dollars, 
alternate base rate ("ABR") (as defined in the A&R Credit Agreement) plus the 
Applicable Margin. The Applicable Margin for Term SOFR, Daily Simple Sonia, or 
EURIBOR could range from
1.50
% to
2.50
% while the Applicable Margin for ABR could range from
0.50
% to
1.50
%.
The weighted-average interest rate on the Company's borrowings under the 
Credit Facility and the 2020 credit facility was
7.03
% and
6.01
% for the three months ended March 31, 2024 and 2023, respectively. The 
weighted-average commitment fee on the revolving line of credit was
0.24
% and
0.23
% for the three months ended March 31, 2024 and 2023, respectively.
                                       12

Seller Note
On November 1, 2023, the Company completed the acquisition of CD for a total 
purchase price of $
246.8
million. This acquisition was funded by borrowings on the Revolving Credit 
Facility and an interest-free note from the seller with aggregate principal 
payments of $
122.9
million (the "Seller Note"). The Seller Note is due and payable in cash with $
50.0
million maturing on November 1, 2024 and $
72.9
million maturing on November 1, 2025. On the acquisition date, the Company 
recorded the Seller Note at its present value of $
109.9
million by discounting the future principal payments using an imputed rate of 
interest of approximately
7.1
% in accordance with accounting guidance in ASC 835, Interest. The Company 
recognized imputed interest expense on the Seller Note of approximately $
2.0
million for the three months ended March 31, 2024.
The Seller Note is secured by certain assets (including equity interest) 
acquired in connection with the acquisition. The Seller Note includes Knowles 
Capital Holdings, Inc. and Knowles Intermediate PD Holdings, LLC as borrowers, 
which jointly and severally agree to pay James P. Kaplan, as representative of 
the sellers of Cornell Dubilier, the principal amount of $
122.9
million as described above. The Seller Note is not interest-bearing except at 
such time as an event of default has occurred, upon which and during the 
continuance of an event of default, all overdue principal will accrue interest 
at 2.0% per annum plus the SOFR-based rate otherwise applicable under the 
Company's existing credit facility. The Seller Note is subject to customary 
conditions and events of default and the secured nature of the Seller Note is 
supported by a Security Agreement.

10. Income Taxes
Income taxes for the interim periods presented have been included in the 
accompanying Consolidated Financial Statements on the basis of an estimated 
annual effective tax rate ("ETR"). The determination of the consolidated 
provision for income taxes requires management to make certain judgments and 
estimates. Changes in the estimated level of annual pre-tax earnings or loss, 
tax laws, and changes resulting from tax audits can affect the overall ETR, 
which impacts the level of income tax expense or benefit and net income or 
loss. Judgments and estimates related to the Company's projections and 
assumptions are inherently uncertain and therefore, actual results could 
differ materially from projections.
The Company's ETR for the three months ended March 31, 2024 and 2023 was
56.1
% and (
26.8
)%, respectively. The ETR includes discrete items totaling $
0.8
million and $
0.6
million of tax expense for the three months ended March 31, 2024 and 2023, 
respectively. The discrete items impacting the tax provision for the three 
months ended March 31, 2024 and 2023 were primarily attributable to 
stock-based compensation. Absent the discrete items, the ETR for the three 
months ended March 31, 2024 and 2023 was
42.1
% and (
12.2
)%, respectively. The Company accrues taxes in various countries where it 
generates income and applies a valuation allowance in other jurisdictions, 
which resulted in the provisions for the three months ended March 31, 2024 and 
2023.
11. Equity Incentive Program
The following table summarizes the stock-based compensation expense recognized 
by the Company for the periods presented:

The number of RSUs vested includes shares that the Company withheld on behalf 
of employees to satisfy statutory tax withholding requirements.
At March 31, 2024, $
35.8
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 2024, 2023, and 2022, the number of PSUs that may be 
earned and vest is based on total shareholder return ("TSR") relative to the 
component companies of the Russell 2000 Index over a three-year performance 
period..

For the three months ended March 31, 2024 and 2023, the weighted-average 
number of anti-dilutive potential common shares for stock-based awards 
excluded from the diluted earnings per share calculation above was
2.1
million and
2.9
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, 2024 and

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations
The following discussion and analysis should be read in conjunction with our 
Consolidated Financial Statements and related Notes included elsewhere in this 
Quarterly Report on Form 10-Q.
Overview
We are a market leader and global provider of high performance capacitors and 
radio frequency ("RF") filtering products, balanced armature speakers, 
advanced micro-acoustic microphones, and audio solutions, serving the medtech, 
defense, electric vehicle, industrial, communications, and consumer 
electronics markets. Our focus on the customer, combined with unique 
technology, proprietary manufacturing techniques, and global operational 
expertise, enables us to deliver innovative solutions across multiple 
applications. References to "Knowles," the "Company," "we," "our," or "us" 
refer to Knowles Corporation and its consolidated subsidiaries, unless the 
context otherwise requires.
We sell our products directly to original equipment manufacturers ("OEMs") and 
to their contract manufacturers and suppliers and through distributors 
worldwide.
Recent Developments
On September 18, 2023, we announced that we are reviewing strategic 
alternatives for the CMM business. This includes a range of possibilities, 
such as: a potential sale, restructuring the business, as well as continuing 
to operate the business as is. No assurance can be given that any transaction 
or other strategic outcomes will result from the review. Further, there can be 
no assurance that the outcome of the strategic alternative review will result 
in our being able to recover the carrying value of the CMM segment. While the 
review is progressing, we have not set a timetable for the conclusion of the 
strategic review and do not intend to comment on or provide updates regarding 
these matters unless and until we determine that further disclosure is 
appropriate or required.
On November 1, 2023, we acquired (i) all the issued and outstanding shares of 
Kaplan Electronics, Inc. and (ii) certain assets of Cornell Dubilier 
Electronics, Inc. and CD Aero, LLC (collectively, "Cornell Dubilier" or "CD") 
for aggregate consideration of $259.8 million, which equated to a total fair 
value of consideration transferred of $246.8 million. The acquired business is 
a manufacturer of film, electrolytic, and mica capacitors used in medtech, 
defense, and industrial electrification applications. The acquisition's 
operations are included in the PD segment. For additional information, refer 
to Note 3. Acquisition to our Consolidated Financial Statements under Part I, 
Item 1, "Financial Statements."
Non-GAAP Financial Measures
In addition to the GAAP financial measures included in this item, we have 
presented certain non-GAAP financial measures. We use non-GAAP measures as 
supplements to our GAAP results of operations in evaluating certain aspects of 
our business, and our executive management team and Board of Directors focus 
on non-GAAP items as key measures of our performance for business planning 
purposes. These measures assist us in comparing our performance between 
various reporting periods on a consistent basis, as these measures remove from 
operating results the impact of items that, in our opinion, do not reflect our 
core operating performance. We believe that our presentation of non-GAAP 
financial measures is useful because it provides investors and securities 
analysts with the same information that we use internally for purposes of 
assessing our core operating performance. The Company does not consider these 
non-GAAP financial measures to be a substitute for the information provided by 
GAAP financial results. For a reconciliation of these non-GAAP financial 
measures to the most directly comparable GAAP financial measures, see the 
reconciliation included herein.

Revenues
Revenues for the first quarter of 2024 were $196.4 million, compared with 
$144.3 million for the first quarter of 2023, an increase of $52.1 million or 
36.1%.
PD revenues increased
$20.6 million due to our acquisition of the CD business, partially offset by 
lower demand from the medtech, industrial, and communication markets in our 
legacy PD business as a result of continued demand weakness associated with 
excess customer and channel inventory. CMM revenues increased $19.9 million, 
primarily due to higher demand in the ear, mobile, and computing markets, 
partially offset by lower average pricing on mature products. MSA revenues 
increased $11.6 million, primarily due to higher shipping volumes of hearing 
health products driven by stronger end market demand. In addition, revenues in 
the first quarter of 2023 were unfavorably impacted by financial incentives 
offered to customers in the fourth quarter of 2022, which resulted in higher 
shipping volumes in the fourth quarter of 2022 and lower revenues in the first 
quarter of 2023.
Cost of Goods Sold
Cost of goods sold ("COGS") for the first quarter of 2024 was $125.5 million, 
compared with $90.4 million for the first quarter of 2023, an increase of 
$35.1 million or 38.8%. This increase was primarily due to our acquisition of 
CD, higher shipping volumes, and lower factory capacity utilization in our 
legacy PD business, partially offset by product cost reductions and fa
vorable foreign currency changes
.
Restructuring Charges
During the first quarter of 2024, we recorded restructuring charges of $1.8 
million related to headcount reductions and $0.7 million for costs associated 
with transferring certain capacitors manufacturing to existing facilities to 
further optimize operations, all within our PD segment. For additional 
information, refer to Note 7. Restructuring and Related Activities to our 
Consolidated Financial Statements.

-------------------------------------------------------------------------------
Table of Contents
During the first quarter of 2023, we recorded restructuring charges of $0.8 
million related to headcount reductions in our CMM segment and $0.3 million 
for other costs. For additional information, refer to Note 7. Restructuring 
and Related Activities to our Consolidated Financial Statements.
Gross Profit and Non-GAAP Gross Profit
Gross profit for the first quarter of 2024 was $69.9 million, compared with 
$53.8 million for the first quarter of 2023, an increase of $16.1 million or 
29.9%. Gross profit margin (gross profit as a percentage of revenues) for the 
first quarter of 2024 was 35.6%, compared with 37.3% for the first quarter of 
2023. The increase in gross profit was primarily due to higher shipping 
volumes, product cost reductions, our acquisition of CD, favorable foreign 
currency changes, and higher factory capacity utilization in our CMM segment, 
partially offset by lower average pricing on mature products shipped into the 
mobile market, lower factory capacity utilization in our legacy PD business, 
our acquisition-related costs of CD, and increased restructuring charges. The 
decrease in gross profit margin was primarily due to lower average pricing on 
mature products shipped into the mobile market, lower factory capacity 
utilization in our legacy PD business, our acquisition-related costs of CD, 
and increased restructuring charges, partially offset by product cost 
reductions, favorable foreign currency changes, and higher factory capacity 
utilization in our CMM segment.
Non-GAAP gross profit for the first quarter of 2024 was $74.7 million, 
compared with $54.4 million for the first quarter of 2023, an increase of 
$20.3 million or 37.3%. Non-GAAP gross profit margin (non-GAAP gross profit as 
a percentage of revenues) for the first quarter of 2024 was 38.0%, compared 
with 37.7% for the first quarter of 2023. The increase in non-GAAP gross 
profit was primarily due to higher shipping volumes, product cost reductions, 
our acquisition of CD, favorable foreign currency changes, and higher factory 
capacity utilization in our CMM segment, partially offset by lower average 
pricing on mature products shipped into the mobile market and lower factory 
capacity utilization in our legacy PD business. The increase in non-GAAP gross 
profit margin was primarily due to product cost reductions, favorable foreign 
currency changes, and higher factory capacity utilization in our CMM segment, 
partially offset by lower average pricing on mature products shipped into the 
mobile market and lower factory capacity utilization in our legacy PD business.

Research and Development Expenses
Research and development expenses for the first quarter of 2024 were $20.6 
million, compared with $20.0 million for the first quarter of 2023, an 
increase of $0.6 million or 3.0%. Research and development expenses as a 
percentage of revenues for the first quarter of 2024 and 2023 were 10.5% and 
13.9%, respectively. The increase in expenses was primarily driven by our 
acquisition of the CD business that increased expenses in our PD segment and 
additional development activities in our MSA segment, partially offset by 
reduced spending in our CMM segment driven by the benefits of prior year 
restructuring actions as we continue to shift our focus and spending to our 
higher margin businesses. The decrease in expenses as a percentage of revenues 
was driven by our higher revenues.
Selling and Administrative Expenses
Selling and administrative expenses for the first quarter of 2024 were $43.5 
million, compared with $33.8 million for the first quarter of 2023, an 
increase of $9.7 million or 28.7%. Selling and administrative expenses as a 
percentage of revenues for the first quarter of 2024 and 2023 were 22.1% and 
23.4%, respectively. The increase in expenses was primarily driven by our 
acquisition of CD. The decrease in expenses as a percentage of revenues was 
driven by higher revenues.
Interest Expense, net
Interest expense for the first quarter of 2024 was $4.4 million, compared with 
$0.8 million for the first quarter of 2023, an increase of $3.6 million. The 
increase is primarily due to imputed interest expense on our Seller Note from 
the CD acquisition, a higher outstanding revolving credit facility balance, 
and higher interest rates during the first quarter of 2024. For additional 
information on borrowings and interest expense, refer to Note 8. Borrowings to 
our Consolidated Financial Statements.

Other (Income) Expense, net
Other income for the first quarter of 2024 was $0.4 million, compared with 
expense of $2.3 million for the first quarter of 2023, a change of $2.7 
million. Income in 2024 primarily represents unrealized gains in our 
investment balances. Expense in 2023 primarily represents unfavorable impacts 
from foreign currency exchange rate changes, partially offset by the 
unrealized gains in our investment balances.
Gain on Sale of Asset, net
The gain on sale of asset of $5.4 million is related to the sale of 
intellectual property previously used in the Intelligent Audio product line, 
which is included the CMM segment. For additional information, refer to Note 
6. Goodwill and Other Intangible Assets.
Provision for Income Taxes and Non-GAAP Provision for Income Taxes
The effective tax rate ("ETR") for the first quarter of 2024 and 2023 was 
56.1% and (26.8)%, respectively. The ETR for the first quarter of 2024 and 
2023 includes discrete items totaling $0.8 million and $0.6 million of tax 
expense, respectively. The discrete items impacting the tax provision for 2024 
and 2023 are primarily attributable to stock-based compensation. Absent the 
discrete items, the ETR for the first quarter of 2024 and 2023 was 42.1% and 
(12.2)%, respectively. The Company accrues taxes in various countries where it 
generates income and applies a valuation allowance in other jurisdictions, 
which resulted in the provision for the first quarter of 2024 and 2023, 
respectively. The change in the ETR was due to the mix of earnings and losses 
by taxing jurisdictions and net discrete items.
The non-GAAP ETR for the first quarter of 2024 and 2023 was 12.7% and 30.1%, 
respectively. The non-GAAP ETR includes discrete items totaling $0.7 million 
and $0.9 million of tax expense for the first quarter of 2024 and 2023, 
respectively. Absent the discrete items, the non-GAAP ETR for the first 
quarter of 2024 and 2023 was 9.4% and 17.8%, respectively. The change in the 
non-GAAP ETR was primarily due to increased utilization of foreign tax credits 
compared to the prior year.
Net Earnings (Loss)
Net earnings for the first quarter of 2024 were $2.5 million, compared with a 
$5.2 million loss for the first quarter of 2023, an increase of $7.7 million. 
As described above, the increase is primarily due to higher gross profit and 
the gain on sale of asset, partially offset by higher operating expenses and 
interest expense.
Earnings (Loss) and Adjusted Earnings Before Interest and Income Taxes
Earnings before interest and income taxes ("EBIT") for the first quarter of 
2024 was $10.1 million, compared with a $3.3 million loss for the first 
quarter of 2023, an increase of $13.4 million. EBIT margin (EBIT as a 
percentage of revenues) for the first quarter of 2024 was 5.1%, compared with 
(2.3)% for the first quarter of 2023. The change is primarily due to higher 
gross profit and the gain on sale of asset, partially offset by higher 
operating expenses.
Adjusted earnings before interest and income taxes ("Adjusted EBIT") for the 
first quarter of 2024 was $25.7 million, compared with $8.1 million for the 
first quarter of 2023, an increase of $17.6 million. Adjusted EBIT margin 
(Adjusted EBIT as a percentage of revenues) for the first quarter of 2024 was 
13.1%, compared with 5.6% for the first quarter of 2023. The increases were 
primarily due to higher non-GAAP gross profit, partially offset by higher 
non-GAAP operating expenses.
Diluted Earnings (Loss) per Share and Non-GAAP Diluted Earnings per Share
Diluted earnings per share was $0.03 for the first quarter of 2024, compared 
with loss per share of $0.06 for the first quarter of 2023, an increase of 
$0.09. As described above, the increase is primarily due to higher gross 
profit and the gain on sale of asset, partially offset by operating expenses 
and interest expense.
Non-GAAP diluted earnings per share was $0.20 for the first quarter of 2024, 
compared with $0.05 for the first quarter of 2023, an increase of $0.15. As 
described above, the increase was primarily due to higher non-GAAP gross 
profit partially offset by higher non-GAAP operating expenses and interest 
expense.

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.

Production transfer costs represent duplicate costs incurred to migrate 
manufacturing to facilities primarily within the United States. These amounts 
are included in the corresponding Gross profit and Earnings (loss) before 
interest and income taxes for each period presented.
(3)
These expenses are related to the acquisition of CD by the PD segment. These 
expenses include ongoing costs to facilitate integration, the amortization of 
fair value adjustments to inventory, and costs incurred by the Company to 
carry out this transaction.
(4)
Other expenses include non-recurring professional service fees related to an 
execution of various reorganization projects, foreign currency exchange rate 
impacts on restructuring balances, and the ongoing net lease cost (income) 
related to facilities not used in operations.
(5)
This gain is related to the sale of intellectual property previously used in 
the Intelligent Audio product line, which is included within the CMM segment.

(6)
Income tax effects of non-GAAP reconciling adjustments are calculated using 
the applicable tax rates in the jurisdictions of the underlying adjustments.

(7)
The non-GAAP reconciling adjustments are those adjustments made to reconcile 
Earnings (loss) before interest and income taxes to Adjusted earnings before 
interest and income taxes
.
(8)
The number of shares used in the diluted per share calculations on a non-GAAP 
basis excludes the impact of stock-based compensation expense expected to be 
incurred in future periods and not yet recognized in the financial statements, 
which would otherwise be assumed to be used to repurchase shares under the 
GAAP treasury stock method.

amortization of fair value adjustments to inventory.                                                                         

Revenues
PD revenues were $74.3 million for the first quarter of 2024, compared with 
$53.7 million for the first quarter of 2023, an increase of $20.6 million or 
38.4%. Revenues increased due to our acquisition of the CD business, partially 
offset by lower demand from the medtech, industrial, and communication markets 
in our legacy PD business as a result of continued demand weakness associated 
with excess customer and channel inventory.
(Loss) Earnings and Adjusted Earnings Before Interest and Income Taxes
PD loss before interest and income taxes was $2.1 million for the first 
quarter of 2024, compared with earnings of $10.7 million for the first quarter 
of 2023, a decrease of $12.8 million. EBIT margin for the first quarter of 
2024 was (2.8)%, compared to 19.9% for the first quarter of 2023. The 
decreases were primarily due to lower gross profit margin and increased 
operating expenses, partially offset by higher revenues. The gross profit 
margin decrease was primarily driven by lower factory capacity utilization in 
our legacy PD business, higher restructuring charges, and the acquisition of 
CD. In addition, gross profit margins decreased as a result of acquisition-relat
ed and production transfer costs associated with the CD business. The increase 
in operating expenses was primarily driven by the acquisition of the CD 
business, which includes higher intangible amortization expenses.
PD Adjusted EBIT was $9.8 million for the first quarter of 2024, compared with 
$13.0 million for the first quarter of 2023, a decrease of $3.2 million. 
Adjusted EBIT margin for the first quarter of 2024 was 13.2%, compared with 
24.2% for the first quarter of 2023. The decreases were primarily due to lower 
non-GAAP gross profit margin, partially offset by higher revenues. The 
non-GAAP gross profit margin decrease was primarily driven by lower factory 
capacity utilization in our legacy PD business and the acquisition of CD.

Revenues
MSA revenues were $57.1 million for the first quarter of 2024, compared with 
$45.5 million for the first quarter of 2023, an increase of $11.6 million or 
25.5%. Revenues increased primarily due to higher shipping volumes of hearing 
health products driven by stronger end market demand. In addition, revenues in 
first quarter of 2023 were unfavorably impacted by financial incentives 
offered to customers in the fourth quarter of 2022 which resulted in higher

Revenues
CMM revenues were $65.0 million for the first quarter of 2024, compared with 
$45.1 million for the first quarter of 2023, an increase of $19.9 million or 
44.1%. Revenues increased primarily due to higher demand in the ear, mobile, 
and computing markets, partially offset by lower average pricing on mature 
products.
Earnings (Loss) and Adjusted Earnings (Loss) Before Interest and Income Taxes
CMM EBIT was $5.3 million for the first quarter of 2024, compared with a $8.2

margin for the first quarter of 2024 was 8.2%, compared with (18.2)% for the 
first quarter of 2023. The increase was primarily due to higher revenues, the 
gain on sale of asset, and higher gross profit margins. The higher gross 
profit margin was driven by product cost reductions, favorable foreign 
currency changes, and increased factory capacity utilization, partially offset 
by lower average pricing on mature products shipped into the mobile market and 
unfavorable product mix.
CMM Adjusted EBIT was $3.0 million for the first quarter of 2024, compared 
with a $4.6 million loss for the first quarter of 2023, an increase of $7.6 
million. Adjusted EBIT margin for the first quarter of 2024 was 4.6%, compared 
to (10.2)% for the first quarter of 2023. The increases in Adjusted EBIT were 
primarily due to higher revenues and higher non-GAAP gross profit margins. The 
higher non-GAAP gross profit margin was driven by product cost reductions, 
favorable foreign currency changes, and increased factory capacity 
utilization, partially offset by lower average pricing on mature products 
shipped into the mobile market and unfavorable product mix.

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 $122.1 million and $87.3 million at March 31, 2024 and 
December 31, 2023, respectively. Of these amounts, cash held by our non-U.S. 
operations totaled
$88.1 million
and $71.8 million as of March 31, 2024 and December 31, 2023, respectively. To 
the extent we repatriate these funds to the U.S., we may be required to pay 
U.S. state income taxes and applicable foreign withholding taxes on those 
amounts during the period when such repatriation occurs. Management will 
continue to reassess our need to repatriate the earnings of our foreign 
subsidiaries. We expect to reduce our cash balance in the second half of the 
year, primarily driven by the payment of the Seller Note related to the CD 
acquisition, share repurchases, and debt reduction, partially offset by cash 
generated from operations.
On November 1, 2023, we acquired (i) all the issued and outstanding shares of 
Kaplan Electronics, Inc. and (ii) certain assets of Cornell Dubilier 
Electronics, Inc. and CD Aero, LLC (collectively, "Cornell Dubilier" or "CD") 
for aggregate consideration of $259.8 million, which equated to a total fair 
value of consideration transferred of $246.8 million. This acquisition's 
operations are included in the PD segment. For additional information, refer 
to Note 3. Acquisitions to our Consolidated Financial Statements.
On September 25, 2023, the Company amended its Amended and Restated Credit 
Agreement (the "A&R Credit Agreement") to, among other things, (a) permit the 
Company in connection with the acquisition of Cornell Dubilier, to incur 
senior priority seller financing indebtedness (the "Seller Note") in an 
aggregate principal amount of $122.9 million secured by certain assets 
(including equity interests) acquired in connection with such acquisition and 
the capital stock of Cornell Dubilier, LLC (the "Acquisition Assets"), which 
shall mature two years after the effective date of such Seller Note (the 
"Seller Note Maturity Date"), (b) extends the requirement to pledge the 
Acquisition Assets that would otherwise constitute collateral under the Credit 
Agreement to the date that is 90 days after the Seller Note Maturity Date, and 
(c) restricts, until the Seller Note Maturity Date, the amount of dispositions 
and investments from the Company and certain of its subsidiaries into Cornell 
Dubilier, LLC and the acquired subsidiaries that constitute Acquisition Assets 
from exceeding $80.0 million the aggregate. All other terms remain the same as 
the A&R Credit Agreement dated February 8, 2023.
On February 8, 2023, we entered into the A&R Credit Agreement that amends and 
restates the prior Credit Agreement (the "2020 Credit Agreement"), which 
provides for a senior secured revolving credit facility with borrowings in an 
aggregate principal amount at any time outstanding not to exceed $400.0 
million. As of March 31, 2024, outstanding borrowings under the Credit 
Facility were $180.0 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. At March 
31, 2024, we have $97.7 million remaining that may yet be repurchased under 
our share repurchase program. The timing and amount of any shares repurchased 
will be determined by us based on our evaluation of market conditions and 
other factors, and will be made in accordance with applicable securities laws 
in either the open market or in privately negotiated transactions. We are not 
obligated to purchase any shares under the program, and the program may be 
suspended or discontinued at any time. The actual timing, number, and share 
price of shares repurchased will depend on a number of factors, including the 
market price of our common stock, general market and economic conditions, and 
applicable legal requirements. Any shares repurchased will be held as treasury 
stock. During the three months ended March 31, 2023, the Company repurchased 
433,759 shares of common stock for a total of $7.5 million. The Company did 
not repurchase any shares of its common stock during the three months ended 
March 31, 2024.

Operating Activities
Cash provided by operating activities adjusts net earnings for certain 
non-cash items, including impairment charges, depreciation expense, 
amortization of intangible assets, stock-based compensation, changes in 
deferred income taxes, and the effects of changes in operating assets and 
liabilities. The decrease in cash provided by operating activities in 2024 as 
compared to 2023 is primarily due to higher incentive compensation and 
restructuring payments in 2024.
Investing Activities
The cash provided by investing activities during 2024 was primarily driven by 
proceeds from the sale of intellectual property. In addition, capital 
expenditures were lower in 2024 as compared to 2023. The cash used in 
investing activities during 2023 was primarily driven by capital expenditures 
to support product innovation and cost savings.
In 2024, we expect capital expenditures to be in the range o
f 3.0% to 4.0% of revenue
s.
Financing Activities
Cash provided by financing activities during 2024 was primarily related to the 
$20.0 million net borrowing of revolving credit facility, partially offset by 
the $5.8 million payment of taxes related to net share settlement of equity 
awards. 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.
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, 2023 filed with the Securities and Exchange Commission on February 21, 
2024. The issuance of recent accounting standards, as included in Note 2. 
Recent Accounting Standards to our Consolidated Financial Statements, is not 
expected to have a significant impact on our revenue, earnings, or liquidity.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
During the three months ended March 31, 2024,
there were no material changes to the information on market risk exposure 
disclosed in our Annual Report on
Form 10-K for the year ended December 31, 2023. For a discussion of our 
exposure to market risk as of December 31, 2023, refer to Item 7A, 
Quantitative and Qualitative Disclosures about Market Risk, contained in our 
Annual Report on Form 10-K for the year ended December 31, 2023.
Item 4
.
Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management has evaluated, under the supervision and with the participation 
of our chief executive officer ("CEO") and chief financial officer ("CFO"), 
the effectiveness of our disclosure controls and procedures (as defined in 
Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as 
amended (the "Exchange Act")) as of the end of the period covered by this 
report. Based on that evaluation, our CEO and CFO have concluded that, as of 
the end of the period covered by this report, our disclosure controls and 
procedures are effective in ensuring that information required to be disclosed 
in our Exchange Act reports is (1) recorded, processed, summarized, and 
reported within the time periods specified in the Securities and Exchange 
Commission's rules and forms, and (2) accumulated and communicated to our 
management, including our CEO and CFO, as appropriate to allow timely 
decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
There has been no change in our internal control over financial reporting that 
occurred during the first quarter of 2024 that has materially affected, or is 
reasonably likely to materially affect, our internal control over financial 
reporting. The Company is in the process of reviewing the internal control 
structure of an acquired business and, if necessary, will make appropriate 
changes as we incorporate our controls and procedures into the recently 
acquired business.
Inherent Limitations on Effectiveness of Controls
Our management, including the CEO and CFO, do not expect that our disclosure 
controls or our internal control over financial reporting will prevent or 
detect all error and all fraud. A control system, no matter how well designed 
and operated, can provide only reasonable, not absolute, assurance that the 
control system's objectives will be met. The design of a control system must 
reflect the fact that the benefits of controls must be considered relative to 
their costs. Further, because of the inherent limitations in all control 
systems, no evaluation of controls can provide absolute assurance that 
misstatements due to error or fraud will not occur or that all control issues 
and instances of fraud, if any, will be detected. These inherent limitations 
include the realities that judgments in decision making can be faulty and that 
breakdowns can occur because of simple error or mistake. Controls can also be 
circumvented by the individual acts of some persons, by intentionally 
falsified documentation, by collusion of two or more individuals within 
Knowles or third parties, or by management override of the controls. The 
design of any system of controls is based in part on certain assumptions about 
the likelihood of future events, and there can be no assurance that any design 
will succeed in achieving its stated goals under all potential future 
conditions. Projections of any evaluation of controls effectiveness to future 
periods are subject to risks. Over time, controls may become inadequate 
because of changes in conditions or deterioration in the degree of compliance 
with policies or procedures.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
Issuer Purchases of Equity Securities
On February 24, 2020, the Company announced that its Board of Directors had 
authorized a share repurchase program of up to $100.0 million of the Company's 
common stock. On April 28, 2022, the Company announced that its Board of 
Directors had increased the authorization by up to $150.0 million in 
additional aggregate value. The timing and amount of any shares repurchased 
will be determined by the Company based on its evaluation of market conditions 
and other factors, and will be made in accordance with applicable securities 
laws in either the open market or in privately negotiated transactions. The 
Company is not obligated to purchase any shares under the program, and the 
program may be suspended or discontinued at any time. The actual timing, 
number, and share price of shares repurchased will depend on a number of 
factors, including the market price of the Company's common stock, general 
market and economic conditions, and applicable legal requirements. Any shares 
repurchased will be held as treasury stock.
The Company did not repurchase any shares of its common stock during the three 
months ended March 31, 2024. As of March 31, 2024, the remaining amount 
authorized for share repurchases was $97.7 million.

              procedures and presented in this report our conclusions about the 
  effectiveness of the disclosure controls and procedures, as of the end of the

 d)    Disclosed in this report any change in the registrant's internal control 
     over financial reporting that occurred during the registrant's most recent

        Annual Report) that has materially affected, or is reasonably likely to 
 materially affect, the registrant's internal control over financial reporting; 
                                                                             and

   The registrant's other certifying officer and I have disclosed, based on our 
    most recent evaluation of internal control over financial reporting, to the 
     registrant's auditors and the audit committee of the registrant's board of 
                     directors (or persons performing the equivalent functions):

          All significant deficiencies and material weaknesses in the design or 
    operation of internal control over financial reporting which are reasonably 
        likely to adversely affect the registrant's ability to record, process, 
                                 summarize and report financial information; and

                                                                              b)
          Any fraud, whether or not material, that involves management or other 
     employees who have a significant role in the registrant's internal control 
                                                       over financial reporting.
