Knowles Reports Q3 2023 Financial Results, Provides Outlook for Q4 2023

and Announces Completion of the Acquisition of Cornell Dubilier

Q3 Diluted EPS at High-End of Guided Range; Q3 Non-GAAP Diluted EPS Above High-End of Guided Range

Q3 Cash from Operations Above High-End of Guided Range

ITASCA, Ill., November 2, 2023 - Knowles Corporation (NYSE: KN) ("Knowles" the "Company"), a leading global supplier of high performance components and solutions, including capacitors and radio frequency (“RF”) filters, advanced medtech microphones and balanced armature speakers, and MEMS microphones for the consumer electronics market, today announced results for the quarter ended September 30, 2023.

"Knowles delivered third quarter results above our gross margin, Non-GAAP Diluted EPS and cash from operations guidance" commented Chief Executive Officer Jeffrey Niew. "Our MedTech & Specialty Audio ("MSA") segment revenues grew 20% versus the prior year as demand has returned to more normalized levels. For Precision Devices ("PD"), revenues continue to be challenged by demand weakness associated with excess channel inventory, however ordering trends have improved. In Consumer MEMS Microphones ("CMM"), Q3 revenues returned to year over year growth. While 2023 has been a challenging year, I am encouraged by the strength of our MSA business, the positive ordering trends in PD, and our team’s ability to generate strong cash flows.”

Mr. Niew continued, "We are pleased to announce the completion of the Cornell Dubilier ("CD") acquisition, and extend a warm welcome to our new partners. This strategic acquisition significantly expands Knowles’ serviceable available market and aligns with key growth tailwinds, including increasing defense budgets, medtech and critical care application growth, as well as industrial electrification and implementation of next generation fast charging architectures. As we enter the next phase of our transformation to an industrial technology company, I am confident these actions will enhance our ability to grow, innovate and deliver greater value to our shareholders.”

Financial Highlights

The following table highlights the Company’s financial performance on both a GAAP and supplemental non-GAAP basis (in millions, except per share data):


	Q3-23	Q2-23	Q3-22
Revenues	$175.1	$173.0	$178.2
Gross profit	$77.5	$73.7	$40.0
(as a % of revenues)	44.3%	42.6%	22.4%
Non-GAAP gross profit	$78.1	$72.7	$68.6
(as a % of revenues)	44.6%	42.0%	38.5%




Diluted earnings per share*	$0.18	$0.15	$0.03
Non-GAAP diluted earnings per share	$0.31	$0.23	$0.25
Net cash provided by operating activities	$39.9	$0.5	$19.1

* Current period results include $0.06 per share in stock-based compensation expense, $0.03 per share in intangibles amortization expense, $0.03 per share in acquisition-related costs, and $0.01 per share in restructuring charges.

Fourth Quarter 2023 Outlook

The forward looking guidance for the quarter ending December 31, 2023 is as follows:


	GAAP	Adjustments	Non-GAAP
Revenues	$210.0 to $220.0 million	—	$210.0 to $220.0 million


Diluted earnings per share	$0.17 to $0.21	$0.10	$0.27 to $0.31
Net cash provided by operating activities	$40.0 to $50.0 million	—	$40.0 to $50.0 million

Q4 2023 GAAP results are expected to include approximately $0.06 per share in stock-based compensation expense, $0.03 per share in intangibles amortization expense, and $0.01 per share in restructuring charges excluded from Non-GAAP results.

Non-GAAP Financial Measures

In addition to the GAAP results included in this press release, Knowles has presented supplemental non-GAAP gross profit, earnings before interest and income taxes, adjusted earnings before interest and income taxes, non-GAAP diluted earnings per share, free cash flow, as well as other metrics on a non-GAAP basis that exclude certain amounts that are included in the most directly comparable GAAP measure to facilitate evaluation of Knowles’ operating performance. Non-GAAP results are not presented in accordance with GAAP. Non-GAAP information should be considered a supplement to, and not a substitute for, financial statements prepared in accordance with GAAP. In addition, the non-GAAP financial measures included in this press release do not have standard meanings and may vary from similarly titled non-GAAP financial measures used by other companies. 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 including, for example, stock-based compensation, certain intangibles amortization expense, impairment charges, restructuring, production transfer costs, and other charges which management considers to be outside our core operating results. Knowles believes that its presentation of these 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. For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures, see the reconciliation table accompanying this release.

Notes:

(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) In 2023, Other expenses include non-recurring professional service fees related to an evaluation of a reorganization. In addition, Other expenses include the ongoing net lease cost (income) related to facilities not used in operations. In 2022, Other expenses represent an adjustment to pre-spin-off pension obligations of $3.4 million, which was recorded during the second quarter of 2022 in Other expense (income), net line on the Consolidated Statements of Earnings, and the ongoing net lease cost related to facilities not used in operations.

(3) These expenses are related to the acquisition of Cornell Dubilier by the Precision Devices segment.

(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 (loss) 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.

2 Safe Harbor Forward Looking Statements This presentation contains forward-looking statements within the meaning of the safe harbor provisions of the United States Private Securities Litigation Reform Act of 1995, such as statements about our future plans, objectives, expectations, financial performance, and continued business operations. The words “believe,” “expect,” “anticipate,” “project,” “estimate,” “budget,” “continue,” “could,” “intend,” “may,” “plan,” “potential,” “predict,” “seek,” “should,” “will,” “would,” “objective,” ”path,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target,” and similar expressions, among others, generally identify forward- looking statements, which speak only as of the date the statements were made. The statements in this presentation, including those statements related to our expectations regarding the acquisition of Cornell Dubilier, are based on currently available information and the current expectations, forecasts, and assumptions of Knowles’ management concerning risks and uncertainties that could cause actual outcomes or results to differ materially from those outcomes or results that are projected, anticipated, or implied in these statements. Other risks and uncertainties include, but are not limited to: unforeseen changes in MEMS microphone demand from our largest customers, particularly our top five customers, who represent a significant portion of revenues for our Consumer MEMS Microphone segment; our ongoing ability to execute our strategy to diversify our end markets and customers; our ability to stem or overcome price erosion in our segments; fluctuations in our stock's market price; fluctuations in operating results and cash flows; our ability to prevent or identify quality issues in our products or to promptly remedy any such issues that are identified; the timing of OEM product launches; risks associated with increasing our inventories in advance of anticipated orders by customers; global economic instability, including due to inflation, rising interest rates, negative impacts caused by pandemics and public health crises, or the impacts of geopolitical uncertainties; the impact of changes to laws and regulations that affect the Company’s ability to offer products or services to customers in different regions; our ability to achieve reductions in our operating expenses; the ability to qualify our products and facilities with customers; our ability to obtain, enforce, defend or monetize our intellectual property rights; disruption caused by a cybersecurity incident, including a cyber attack, cyber breach, theft, or other unauthorized access; difficulties or delays in and/or the Company’s inability to realize expected synergies from its acquisitions; increases in the costs of critical raw materials and components; availability of raw materials and components; managing new product ramps and introductions for our customers; our dependence on a limited number of large customers; our ability to maintain and expand our existing relationships with leading OEMs in order to maintain and increase our revenue; increasing competition and new entrants in the market for our products; our ability to develop new or enhanced products or technologies in a timely manner that achieve market acceptance; our reliance on third parties to manufacture, assemble, and test our products and sub-components; escalating international trade tensions, new or increased tariffs and trade wars among countries; financial risks, including risks relating to currency fluctuations, credit risks and fluctuations in the market value of the Company; a sustained decline in our stock price and market capitalization may result in the impairment of certain intangible or long-lived assets; market risk associated with fluctuations in commodity prices, particularly for various precious metals used in our manufacturing operation, and changes in tax laws, changes in tax rates and exposure to additional tax liabilities; and other risks, relevant factors, and uncertainties identified in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, subsequent Reports on Forms 10-Q and 8-K and our other filings we make with the U.S. Securities and Exchange Commission. These forward-looking statements speak only as of the date of this presentation, and Knowles disclaims any intention or obligation to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Non-GAAP Disclaimer The financial results disclosed in this presentation include certain measures calculated and presented in accordance with GAAP. In addition to the GAAP results included in this presentation, Knowles has presented supplemental, non-GAAP gross profit, adjusted earnings before interest and income taxes, adjusted earnings before interest and income taxes margin, adjusted earnings before interest, taxes, depreciation, and amortization; adjusted earnings before interest, taxes, depreciation, and amortization margin; non-GAAP gross profit margin, non-GAAP diluted earnings per share, non-GAAP operating expense; free cash flow; and free cash flow margin to facilitate evaluation of Knowles’ operating performance. These non-GAAP financial measures exclude certain amounts that are included in the most directly comparable GAAP measure. In addition, these non-GAAP financial measures do not have standard meanings and may vary from similarly titled non-GAAP financial measures used by other companies. Knowles uses non-GAAP measures as supplements to its GAAP results of operations in evaluating certain aspects of its business, and its executive management team focuses on non-GAAP items as key measures of Knowles’ performance for business planning purposes. These measures assist Knowles in 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 these 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. For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures, see the reconciliation tables in the Appendix.

• Revenue down YoY primarily due to lower Precsion Devices revenue driven by excess customer and channel inventory and timing of defense shipments • Non-GAAP Gross Profit Margin of 44.6%, up 610bps versus prior year primarily due to the gain on sale of fully depreciated assets, productivity improvements, and lower factory costs, partially offset by lower capacity utilization • Adjusted EBIT Margin up 520bps YoY driven by favorable gross profit margins, reduced spending in CMM, and lower incentive compensation costs in PD, partially offset by higher professional and legal fees associated with the exploration of strategic alternatives for CMM * For this Non-GAAP financial measure see the Appendix for GAAP to Non-GAAP reconciliation 3 Solid Q3 performance, in line with expectations Q3 2023 Year-over-Year 178.2 175.1 3Q 22 3Q 23 38.5 44.6 3Q 22 3Q 23 REVENUE ($M) Non-GAAP GROSS PROFIT MARGIN* (%) 15.8 21.0 3Q 22 3Q 23 ADJUSTED EBIT MARGIN* (%) +520 bps Non-GAAP DILUTED EPS* ($) 0.25 0.31 3Q 22 3Q 23 +24.0%-1.7% +610 bps
