Knowles

Knowles makes tiny parts for hearing aids and defense equipment. Their components help medical devices and cars work better. They serve brands that build advanced electronics for people.

Small Parts for Big Tech

• Precision Devices: Custom capacitors and radio frequency filters for defense and industrial markets; accounts for 55% of revenue in 2025.
• Medtech & Specialty Audio: Microphones and speakers for hearing health and specialty audio applications; represents 45% of revenue in 2025.
• Capacitors: Specialized electronic parts that manage high voltage and temperatures in electric vehicles and medical implants.
• Balanced Armature Speakers: Miniature, high-quality audio components used by leading hearing aid manufacturers such as WS Audiology.

Recent Strategic Moves

• Sold the consumer microphone business to Syntiant Corp in December 2024 to focus on industrial technology.
• Expanded the reach of film capacitors into new energy sectors during 2025.
• Integrated the CD acquisition to increase its market presence in specialty film capacitors.
• Authorized a $150 million increase to the share repurchase program in February 2025.

Why They Stand Out

Knowles operates in 11 countries with manufacturing and engineering sites across North America, Europe, and Asia. Its deep engineering expertise allows it to customize tiny electronic parts for specific customer needs at a large scale.

Performance at a Glance

• Revenue reached $593 million for the full year 2025, up 7.2% from the previous year.
• Net income rose to $50.9 million in 2025, compared with $23.4 million in 2024.
• Q1 2026 revenue hit $153.1 million, a 15.8% increase over the same period in 2025.
• Operating income grew to $16.1 million in Q1 2026, up 103.8% year-over-year.

The Final Word

Knowles has shifted its focus from consumer electronics toward higher-margin industrial and medical markets. This transition centers on specialized components that provide critical functions in defense, energy, and hearing health.
