Lumentum's stock surged 5% in pre-market trading, extending its recent gains as investors reacted to bullish industry reports and anticipation of the company's quarterly results.

Research reports indicate that the AI computing supply chain has entered a deep expansion phase, with downstream demand forcing upstream capacity buildouts. Lumentum's core optical component capacity may be sold out through 2028, significantly elevating capacity shortage expectations and driving multi-year order visibility. This has fueled optimism for the company's long-term growth in AI optical communications.

Additionally, the company is scheduled to report quarterly earnings after market close on August 11. Consensus estimates project revenue of approximately $9.88 billion, representing 111.83% year-over-year growth, and adjusted EPS of approximately $2.97, up 271.06% year-over-year. The strong growth is driven by sustained shipments of high-end components and product mix upgrades lifting average selling prices, further supporting bullish sentiment.
