Key risks (from latest filing)
["Geopolitical concentration: Rising demand for domestic manufacturing footprints in defense markets exposes the company to trade barriers, tariffs, and supply chain disruptions if unable to expand production capacity domestically.","Customer concentration and OEM dependency: The company sells primarily to OEMs in highly specialized markets (defense, medtech, hearing health); loss of a major customer or shift in their purchasing patterns could significantly impact revenues.","Technology obsolescence and innovation competition: Success depends on continuous innovation and customization capability; failure to keep pace with rapid technological change in RF, power electronics, or hearing health technologies could erode competitive position."]
