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 1: 'customers outside the United States based on the geographic region and country where our product is initially shipped to represented 79.2%, 81.0% and 73.8% of net revenue'”
“10-K Item 1A: 'some of our suppliers are our sole sources for certain materials, equipment and components'”
“10-K Item 1: 'Customer A| 26.6 | %| | 15.4 | %| | 18.9 | %'”
“10-K Item 1: 'Customer B| 15.0 | %| | 16.0 | %| | 11.4 | %'”
Lumentum carries concentrations on both the demand and supply sides. Customers outside the United States represented 79.2% of net revenue, a high-share, structural geographic exposure that ties results to international trade conditions. On the supply side, some suppliers are sole sources for certain materials, equipment and components, a high-share dependency and the most idiosyncratic risk in the set, since a single supplier interruption could constrain output. Customer concentration is the item most likely to move the verdict. Customer A was 26.6% of the disclosed share, a medium-share dependency whose weight has risen across the periods shown in the filing, while Customer B was 15%, a low-share dependency. Both are counterparty-specific: a changed order pattern from either would show up directly in revenue. Netting these out, the geographic skew is structural and slow-moving, while the customer and sole-source exposures are the sharper, relationship-driven risks.
