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, including risks relating to the COVID-19 pandemic and governmental responses to it, including but not limited to, the impact on our supply chain, power disruptions, customer demand, and costs associated with our operations. Other risks and uncertainties include, but are not limited to: unforeseen changes in MEMS microphone demand from our largest customers, in particular, two North American, a Korean, and Chinese OEM customers; 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; the impact of changes to laws and regulations that affect the Company’s ability to offer products or services to customers in different regions; risks associated with shareholder activism, including proxy contests; our ability to achieve continued 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; 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; 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, 2020, as updated in our Quarterly Report on Form 10-Q for the quarter ended June 30,2021, 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, earnings before interest and income taxes, adjusted earnings before interest and income taxes, adjusted earnings before interest and income taxes margin, non-GAAP gross profit margin, non-GAAP diluted earnings per share, free cash flow, free cash flow margin, and non-GAAP operating expense 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.

Appendix 34

July 28, 2021 Q4 2021 Projections § July 28, 2021 35 GAAP ADJUSTMENTS NON-GAAP Revenue $230–235M — $230–235M Gross Profit Margin 40.5–41.0% 0.3% 40.0–42.0% Diluted EPS $0.32–0.34 $0.11 $0.43–0.45 Projections as of November 30, 2021; Q4 2021 GAAP results are expected to include approximately $0.07 per share in stock-based compensation and $0.04 per share in amortization of intangibles and debt discount. Q4 2021 GAAP guidance does not consider the impact of a potential positive adjustment to the valuation allowance for our U.S. subsidiary. The potential benefit would not impact non-GAAP results.

Calculated as results for the nine months ended September 30, 2021 plus the midpoint of Q4 2021 projections. (2) Production transfer costs represent duplicate costs incurred to migrate manufacturing to facilities primarily in Asia. These amounts are included in the corresponding Gross profit and Earnings from continuing operations before interest and income taxes for each period presented. (3) In 2021, Other expenses represent the ongoing net lease cost (income) related to facilities not used in operations and expenses related to the acquisition of Integrated Microwave Corporation by the Precision Devices segment. In 2017, Other primarily represents expenses related to the acquisition of certain assets of a capacitors manufacturer. (4) The non-GAAP reconciling adjustments are those adjustments made to reconcile Earnings from continuing operations before interest and income taxes to Adjusted earnings from continuing operations before interest and income taxes. (5) Under GAAP, certain convertible debt instruments that may be settled in cash (or other assets) upon conversion are required to be separately accounted for as liability (debt) and equity (conversion option) components of the instrument in a manner that reflects 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 is excluded from management’s assessment of the Company’s operating performance because management believes that this non-cash expense is not indicative of its core, ongoing operating performance. (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 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 to offset any potential dilution from the convertible notes. Although the anti-dilutive impact of the convertible note hedges is not reflected under GAAP, the Company includes the anti-dilutive impact of the convertible note hedges in non-GAAP diluted average shares outstanding, if applicable.
