Lumentum spent years as a forgotten laser supplier riding smartphone cycles before something shifted in its order book and turned patient holders into unlikely winners. The catch is how long that patience actually had to last.
Whether you're a value, growth, or momentum investor, finding strong stocks becomes easier with the Zacks Style Scores, a top feature of the Zacks Premium research service.
Lumentum and Coherent both reported blockbuster quarters fueled by AI datacenter demand, with order books stretching years into the future.
Lumentum Holdings (LITE) is a high-growth, AI infrastructure-exposed business with rapidly increasing free cash flow and strong net cash of $1.1 billion. I anticipate LITE's fiscal 2027 revenue growth could reach 70% year-over-year, with Wall Street estimates potentially even higher. Despite trading at 59x forward free cash flow, LITE's adjusted PEG ratio is below 1x, making it an attractive bargain for patient investors.
Lumentum's order book is booked solid through early 2029, yet its stock is leading the entire AI optics sector lower today.
Lumentum Holdings (LITE) demonstrates accelerating revenue growth and margin expansion, driven by premium product offerings and operational efficiencies. LITE's Systems segment is outpacing Components, with key drivers including OCS solutions, 1.6T transceivers, and high-power lasers for CPO/NPO architectures. Gross margin reached 50% at $1B revenue—well ahead of previous targets—supported by scale, high manufacturing yields, and pricing power in a duopoly market.
Lumentum's recent stock pullback in tandem with broader market volatility contrasts with strengthening fundamentals, as management confirms sold-out capacity through early 2029. Accelerating optical adoption across scale-up, scale-out, and scale-across AI networking architectures reinforces long-term demand visibility—especially as Lumentum transitions towards higher-value SKUs like 1.6T transceivers and 200G laser modules. Higher ASP products, alongside expanding manufacturing capacity and sustained supply-led pricing tailwinds, support incremental margin expansion and FCF growth.
Lumentum is now at a demand inflection point as high-speed optical networking becomes a critical AI data center bottleneck. LITE faces significant demand-supply gaps, unable to meet 70% of demand for some products through next year, supporting elevated margins through FY2028. With management targeting $40 adjusted EPS by FY2028 and strong order flow, LITE could be materially undervalued if execution is successful.
Lumentum shares are rallying Friday after the company said it's selling out of AI server products.
Lumentum Holdings (NASDAQ:LITE) shares rose over 4% on Friday morning after the optical technology supplier warned that strong demand from artificial intelligence (AI) data centers had effectively booked its production capacity through early 2029. CEO Michael Hurlston told Bloomberg Television in Tokyo that demand for optical and laser components used in high-speed data transmission continued to outstrip the company's ability to increase manufacturing output.
Lumentum says demand for some optical components will exceed supply through 2028, lifting its shares and other optical networking stocks.
Shares of Lumentum Holdings LITE rose 6% in pre-market trading on Friday after Chief Executive Officer Michael Hurlston said demand for the company's optical components had exceeded available supply, with orders booked through early 2029. The company is struggling to keep pace with demand from technology firms expanding artificial intelligence data centres.
