KN Company Overview

Knowles Corporation is a U.S.-based specialty components manufacturer focused on advanced micro-acoustic, precision device, and high-performance capacitor technologies for industrial, defense, medical, electrification, and consumer applications. The company operates primarily in the electronic components and advanced manufacturing industries, supplying engineered products that are integrated into mission-critical systems and devices. Its core revenue drivers include precision capacitors, radio frequency and microwave solutions, balanced armature speakers, microphones, and specialty electronic components used in aerospace, communications, hearing health, electric vehicles, and industrial automation markets.

The company traces its origins to the Knowles Electronics business founded in 1946, historically recognized for miniature acoustic components and balanced armature speaker technology. Knowles Corporation became an independent publicly traded company in 2014 following its spin-off from Dover Corporation. Over time, the company diversified beyond consumer acoustics into higher-margin industrial and defense-oriented markets through acquisitions, portfolio optimization, and expansion into precision electronics and medtech-related applications. Public disclosures in SEC filings and investor presentations consistently describe the company’s strategy as emphasizing engineered solutions with high reliability requirements and specialized intellectual property.
