Each card carries a disclosed-size chip (HIGH / MEDIUM / LOW — how large the exposure is as a share of revenue, not how dangerous it is) and a nature tag: Built-in(the company’s own model, geography, or products) or Outside party (an external customer, supplier, or distributor it relies on).
“10-K Item 1A: 'Our customers that supply various systems and components to automotive OEMs accounted for 70.6%...of our total net sales in fiscal years 2026, 2025, and 2024, respectively.'”
“10-K Item 1A: 'We currently rely on a limited number of third-party wafer fabrication facilities for the fabrication of semiconductor wafers'”
“10-K Item 1A: 'We rely heavily on the manufacturing operations at AMPI, which operates as our primary internal assembly and testing facility.'”
Allegro MicroSystems carries a concentrated exposure on both the customer and supply sides, and the two interact in ways that compound the overall risk profile. On the demand side, customers supplying systems and components to automotive OEMs accounted for 70.6% of total net sales, making automotive the dominant revenue channel by a high share. This is a structural exposure rather than a dependency on named individual buyers — it reflects where Allegro's product portfolio fits in the semiconductor supply chain — but the practical effect is that automotive production cycles, EV adoption rates, and content-per-vehicle trends are the primary levers that move the top line. On the supply side, the company relies on a limited number of third-party wafer fabrication facilities for semiconductor wafer production, and separately relies heavily on the manufacturing operations at AMPI as its primary internal assembly and testing facility. Both are moderate-share dependencies by disclosed size, but they are structurally interlinked — wafer fabrication and assembly and test are sequential steps in the production process, meaning a disruption in either one constrains the output of the other. The net picture is a high-share customer tilt toward automotive combined with moderate-share supply-chain concentration at two production-critical steps. A shock to auto demand or a disruption at a key fab or the AMPI facility would not be easily absorbed given the limited redundancy on either side. Automotive end-market health and manufacturing continuity are the two variables most worth monitoring for this profile.
