Risk factors and legal proceedings

The risks Knowles Corp names in Item 1A of its 10-K filed Feb 9, 2026: 23 risks under these headings, as written.⁵

• Cautionary Statement Concerning Forward-Looking Statements
• Risks Related To Our Business
• We derive a significant portion of our revenues from a limited number of OEM customers and distributors. If revenues derived from these partners decrease or the timing of such revenues fluctuates, our operating results could be adversely affected.
• A significant portion of revenues for our Precision Devices segment depends on U.S. government contracts, which require us to comply with various procurement laws and regulations. Failure to comply with these laws and regulations could result in an interruption or termination of our government contractor status, which could have a adverse impact on our results of operation.
• We rely on highly specialized suppliers for a variety of highly engineered or specialized components, and other inputs for which we may not be able to readily identify alternatives or substitutes in the event of a supply disruption or capacity constraint at or by any of these suppliers, which could have a material adverse impact on our results of operations.
• Implementation of our growth strategies may not be successful, which could adversely impact our results of operations.
• If we are unsuccessful in implementing our acquisition strategy, integrating acquired companies, or managing divestitures and other significant transactions our business and financial results may be adversely effected.
• Our success depends on our ability to attract and retain key employees, and if we are unable to attract and retain such qualified employees, our business and our ability to execute our business strategies may be materially impaired.
• Our effective tax rate may fluctuate which will impact our future financial results.
• Our products are complex and could contain defects, which could result in material costs to us and harm our business, results of operations, and financial condition.
• Risks Related to Our Industry
• Global markets for our products are highly competitive and subject to rapid technological change. If we are unable to develop new products and compete effectively in these markets, our financial condition and operating results could be materially adversely affected.
