What Knowles Corp does

In the company’s own words

Knowles Corporation (NYSE: KNX) is a leading manufacturer of specialty electronic components headquartered in the United States with a global presence across eleven countries. The company designs and produces high-performance capacitors, radio frequency filters, advanced microphones, and balanced armature speakers that enable critical functions in demanding applications.

The company operates approximately 5,200 employees worldwide and maintains manufacturing, sales, and engineering facilities across North America, Europe, and Asia.

Knowles operates through two reportable segments. The Precision Devices segment, representing 55 percent of consolidated revenues, specializes in high-performance capacitors and RF filtering solutions for defense, industrial, medtech, and electrification/energy applications.

Fund ownership is a floor, not a census — pensions, insurers and people holding shares directly are not visible here.

Fund ownership counts N-PORT filers only, so it is a floor rather than a census — pensions, insurers and direct holders are not visible here, and the remainder is not “held by individuals”.

Fund ownership is a subset of institutional 13F ownership — the two describe overlapping populations and must not be added together.
