What these concentrations mean together
updated 2026-06-24The company's concentration profile is driven by two large-share exposures — a customer revenue concentration in the Medical and Sound Architecture (MSA) segment and a sole-source supplier dependency for critical components — with two lower-share individual customer relationships adding further specificity. The MSA segment's top five customers accounted for approximately 76% of its revenues, a large share by disclosed size and dependency in character. Because this is a segment-level figure rather than a consolidated measure, the impact on the overall company depends on the weight of the MSA segment in total revenues. Two named customers illustrate the concentration within that cohort: WS Audiology A/S accounted for approximately 11% of consolidated Company revenues and TTI, Inc. accounted for approximately 10% of consolidated Company revenues, both low shares at the consolidated level. The gap between the segment's high concentration and the modest consolidated share of each name suggests the MSA segment itself is a significant but not dominant portion of total revenues. The supplier dependency is the most idiosyncratic element: ASIC and MEMS foundry partners are identified as sole sources of supply, a large disclosed share and dependency in character. Sole-source foundry relationships for custom semiconductor and sensor components carry operational risk that cannot be resolved through inventory buffers alone — a disruption at a specialized foundry partner would impair production in a way that takes significant time to resolve. Together the most material watch variables are the health of the top-five MSA customer relationships and the continuity of the sole-source foundry arrangements for critical components.
