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: 'we rely on suppliers such as Panasonic and Contemporary Amperex Technology Co. Limited (CATL) for these cells. We have to date fully qualified only a very limited number of such suppliers and have limited flexibility in changing suppliers.'”
“10-K Item 1A: 'Our products contain thousands of parts purchased globally from hundreds of suppliers, including single-source direct suppliers, which exposes us to multiple potential sources of component shortages.'”
Tesla's disclosed concentration risk sits entirely on the supply side and is high-sized across both data points. The company relies on suppliers such as Panasonic and Contemporary Amperex Technology Co. Limited (CATL) for battery cells, having to date fully qualified only a very limited number of such suppliers, which leaves Tesla with limited flexibility in changing suppliers — a dependency exposure specific to the battery cell supply chain that underpins vehicle production. More broadly, Tesla's products contain thousands of parts purchased globally from hundreds of suppliers, including single-source direct suppliers, which exposes the company to multiple potential sources of component shortages. These two exposures compound one another rather than standing independently: the battery cell dependency on Panasonic and CATL is the more acute and specific of the two, since batteries are a core, high-value input with few qualified alternative suppliers, while the broader single-source supplier base across thousands of parts represents a wider but more diffuse operational risk — any one of many single-source relationships failing could interrupt production somewhere in the vehicle. Neither exposure is customer- or revenue-mix concentration; both describe supply chain fragility, meaning Tesla's production continuity is the more relevant sensitivity here than demand or customer concentration.
