Lumentum Holdings shares rose 11.14% on September 8, 2026, moving toward $980 after opening near $898 and approaching $994 during intraday trading. The advance extended a recent rally in which closing prices climbed from about $827 toward $979. Deutsche Bank initiated coverage with a Buy rating and a $1,200 price target on August 31, while Evercore ISI began coverage with an Outperform rating and a $1,100 target. Both firms highlighted Lumentum’s role in optical networking for AI data centers, where faster processors are increasing demand for high-speed connectivity. Chief Executive Michael Hurlston said at the Deutsche Bank Technology Conference on August 27 that orders and order rates had increased significantly. Management sees potential earnings of about $40 per share in fiscal 2028, driven mainly by stronger optical-product demand. Lumentum reported about $3.01 billion in revenue and a gross margin near 41.7%, although weak current profitability and elevated price-to-sales and price-to-cash-flow ratios leave the stock sensitive to changes in growth expectations. Recent Form 4 filings showed senior-executive share sales totaling about $11.5 million, while the executives retained sizable holdings. Investors are monitoring order growth, analyst revisions, insider activity and AI networking demand as the stock tests the upper end of its recent range.
