Lumentum Holdings (LITE) concentration risks

Lumentum Holdings' concentration risk spans both supply and customer relationships, though the disclosures point to a business that has already worked through part of its customer concentration. On the supply side, some of the company's suppliers are sole sources for certain materials, equipment, and components, a high-share dependency that leaves limited room to substitute if any one of those relationships were disrupted. On the customer side, the more notable disclosure is retrospective rather than current: Lumentum stopped all product shipments to Huawei, historically its largest networking customer in China, at the beginning of calendar year 2024, a medium-share exposure whose character is dependency-based even though the relationship has already been severed. That timing matters for how investors should read it — the Huawei exposure is now a completed transition rather than an ongoing risk, meaning the current revenue base no longer carries that specific counterparty dependency, while the sole-source supplier risk remains a live, structural vulnerability in ongoing operations. Overall, the supply-side dependency is the more forward-looking risk to monitor, whereas the Huawei disclosure mainly explains a past revenue step-down rather than a present-day concentration.
