Knowles Reports Q2 2023 Financial Results and Provides Outlook for Q3

Q2 Gross Profit Margins Exceed High-End of Guided Range

Q2 Diluted EPS at High-End of Guided Range; Q2 Non-GAAP Diluted EPS Above Mid-Point of Guided Range

ITASCA, Ill., August 2, 2023 - Knowles Corporation (NYSE: KN) ("Knowles" the "Company"), 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, today announced results for the quarter ended June 30, 2023.

"Knowles delivered solid results for the second quarter" commented Chief Executive Officer Jeffrey Niew. "Our MedTech & Specialty Audio ("MSA") segment delivered better than expected results as customer inventory levels declined faster than we originally anticipated. For Precision Devices ("PD"), Q2 revenues finished below our expectations due to further demand weakness associated with excess channel inventory in the industrial and distribution markets and timing of shipments into the defense market. In Consumer MEMS Microphones ("CMM"), Q2 benefited from favorable mix as demand into computing end markets was better than expected.

"We have reduced our revenue and earnings outlook for the second half of 2023 as we expect customer demand to remain soft in PD due to elevated inventory levels at our industrial and distribution customers and the timing of bookings in the defense market. In MSA, customer inventory levels have returned to more normalized levels and we are projecting a return to year over year growth starting in Q3. Lastly for CMM, trends for non-mobile applications have improved but further challenges in the smartphone market are delaying a return to growth for this segment."

Mr. Niew continued, "The long-term secular trends in the markets we serve remain positive and despite the near term market challenges our strategy to focus on higher margin markets and products coupled with Knowles operational excellence gives us confidence to achieve our mid-term financial targets."

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):


	Q2-23	Q1-23	Q2-22
Revenues	$173.0	$144.3	$188.0
Gross profit	$73.7	$53.8	$77.7
(as a % of revenues)	42.6%	37.3%	41.3%
Non-GAAP gross profit	$72.7	$54.4	$78.1
(as a % of revenues)	42.0%	37.7%	41.5%




Diluted earnings (loss) per share*	$0.15	$(0.06)	$(2.64)
Non-GAAP diluted earnings per share	$0.23	$0.05	$0.33
Net cash provided by operating activities	$0.5	$21.9	$19.6

* Current period results include $7.1 million in stock-based compensation, $1.1 million in net restructuring credits, and $2.9 million in intangibles amortization expense.

Third Quarter 2023 Outlook

The forward looking guidance for the quarter ending September 30, 2023 is as follows:


	GAAP	Adjustments	Non-GAAP
Revenues	$170.0 to $180.0 million	—	$170.0 to $180.0 million
Gross Profit Margin	41.2% to 43.2%	0.3%	41.5% to 43.5%

Diluted EPS	$0.14 to $0.18	$0.12	$0.26 to $0.30

Q3 2023 GAAP results are expected to include approximately $0.06 per share in stock-based compensation, $0.03 per share in amortization of intangibles, $0.02 per share in restructuring charges, and $0.01 per share of other costs 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 relate to non-recurring professional service fees incurred primarily in the second quarter including an evaluation of restructuring actions. In addition, Other expenses include the ongoing net lease cost 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) Income tax effects of non-GAAP reconciling adjustments are calculated using the applicable tax rates in the jurisdictions of the underlying adjustments.

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

(5) The number of shares used in the diluted per share calculations on a non-GAAP basis excludes the impact of stock-based compensation expense expected to be incurred in future periods and not yet recognized in the financial statements, which would otherwise be assumed to be used to repurchase shares under the GAAP treasury stock method.

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 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 cost 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 excess customer and channel inventory and timing of defense shipments. • Gross Profit Margin of 42.0%, up 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 down YoY driven by lower revenue volumes and increases in professional and legal fees * For this Non-GAAP financial measure see the Appendix for GAAP to Non-GAAP reconciliation 3 Solid Q2 performance, in line with expectations Q2 2023 Year-over-Year 188.0 173.0 2Q 22 2Q 23 41.5 42.0 2Q 22 2Q 23 REVENUE ($M) Non-GAAP GROSS PROFIT MARGIN* (%) 20.0 16.0 2Q 22 2Q 23 ADJUSTED EBIT MARGIN* (%) -400 bps Non-GAAP DILUTED EPS* ($) 0.33 0.23 2Q 22 2Q 23 -30.3%-8.0% +50 bps

In addition, Other expenses include the ongoing net lease cost 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.

Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures 10 Quarter Ended June 30, (in millions, except per share amounts) 2023 2022 Net earnings (loss) $ 13.6 $ (242.9) Interest expense, net 0.8 0.8 Provision for income taxes 3.8 25.8 Earnings (loss) before interest and income taxes $ 18.2 $ (216.3) Non-GAAP reconciling adjustments (2) 9.5 253.9 Depreciation expense 8.2 11.0 Adjusted earnings before interest, income taxes, depreciation, and amortization ("EBITDA") $ 35.9 $ 48.6 Adjusted EBITDA margin 20.8 % 25.9 % Net earnings (loss) $ 13.6 $ (242.9) Non-GAAP reconciling adjustments (2) 9.5 253.9 Income tax effects of non-GAAP reconciling adjustments (3) 1.2 (20.7) Non-GAAP net earnings $ 21.9 $ 31.7 Diluted earnings (loss) per share $ 0.15 $ (2.64) Earnings per share non-GAAP reconciling adjustment 0.08 2.97 Non-GAAP diluted earnings per share $ 0.23 $ 0.33 Diluted average shares outstanding 91.8 92.0 Non-GAAP adjustment (4) 3.1 3.4 Non-GAAP diluted average shares outstanding (4) 94.9 95.4 Notes: (2) 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. (3) Income tax effects of non-GAAP reconciling adjustments are calculated using the applicable tax rates in the jurisdictions of the underlying adjustments.
