Lumentum shares surged 5.26% in pre-market trading, extending a rally driven by upbeat sentiment ahead of the company's quarterly earnings report.

The company is scheduled to report results after the close on August 11, with consensus estimates calling for revenue of approximately $9.88 billion, up 111.83% year-over-year, and adjusted EPS of roughly $2.97, up 271.06% year-over-year. The core growth driver stems from sustained shipments of high-end optical components and product mix upgrades lifting average selling prices.

Additionally, institutional research indicates that the AI computing power supply chain has entered a deep demand-driven capacity explosion phase, and Lumentum's core optical component capacity may be sold out through 2028, significantly heightening supply shortage expectations. The combination of an optimistic earnings outlook and the capacity tightness narrative continues to support market sentiment ahead of the report.
