Fidelity Growth Strategies Fund Shilpa Mehra | “An overweight in Lumentum Holdings (+127%), a provider of optical and photonic components used in high-speed communications applications, also helped. In early November, the company reported better-than-expected quarterly earnings, with results especially strong in its Cloud & Networking segment, which represents about 80% of the business. We increased the position during the past three months. BSD Analysis: Lumentum Holdings enters 2026 delivering a "standout" performance, with 65% year-over-year revenue growth and a non-GAAP operating margin that expanded by over 1,700 basis points. The company is successfully scaling its Optical Circuit Switches (OCS) to meet extraordinary customer demand, recently reporting a backlog exceeding $400 million. For 2026, the investment case is anchored by the ramp-up of co-packaged optics (CPO), supported by a new multi-hundred-million-dollar order for delivery in 2027. Management expects Q3 2026 revenue to reach up to $830 million, representing a 25% sequential increase as the AI and cloud data center markets accelerate. While the broader networking market remains competitive, Lumentum's deep technological moat in laser and photonic solutions provides significant pricing power. For investors, Lumentum offers high-leverage exposure to the "physical layer" of AI infrastructure, where hardware constraints are the primary bottleneck for growth.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Invesco Small Cap Value Fund Jonathan Edwards, Jonathan Mueller | “Shares of this market-leading designer and manufacturer of innovative optical and photonic products rallied in the fourth quarter, fueled by apparent investor enthusiasm for its AI-driven growth potential. BSD Analysis: Lumentum Holdings is a key under-the-radar beneficiary of the 2026 AI infrastructure boom, providing the essential optical components for high-speed data center networking. The company is seeing surging demand for its 800G and next-generation 1.6T transceiver modules as cloud hyperscalers race to build out their AI-optimized clusters. For 2026, the investment thesis is anchored by a significant recovery in the telecommunications segment, as the global push for 5G-Advanced drives a new cycle of carrier spending. Management is successfully diversifying its revenue beyond traditional networking, with its 3D sensing and industrial laser divisions capturing new growth in the automotive and AR/VR markets. While the firm faces intense competition in the optical space, its deep technological moat and manufacturing scale provide a durable competitive advantage. Financial results are expected to show a meaningful expansion in gross margins as the product mix shifts toward higher-value AI components. For 2026, Lumentum remains a premier "picks-and-shovels" play for the global digital economy.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
