Marvell Q2 Earnings Preview: AI Growth and Valuation in Focus

Jim Cramer said Broadcom CEO Hock Tan told him demand for AI compute infrastructure remains extremely strong and durable, with the custom chip designer holding more orders than almost anybody other than Jensen Huang. Cramer's remarks on CNBC center on whether Broadcom can keep capturing custom AI chip orders, and the third quarter earnings released on September 2nd support the growth narrative, with revenue up 86%, AI semiconductor revenue up 221%, and fiscal year 2026 guidance implying 186% annual AI revenue growth. Tan reaffirmed that Broadcom could pull in $115 billion in annual AI chip sales in 2027 and $230 billion in 2028. Still, the fiscal fourth quarter guide left investors wanting more, with $34.8 billion in revenue missing analyst estimates of $35.03 billion and gross margin guided at 73%, a five point annual drop due to a higher mix of XPU sales. Estimates suggest 71% of Broadcom's fiscal 2027 and 2028 XPU deployment could rely on OpenAI and Anthropic, meaning a huge portion of orders might come from firms now calling for a slowdown in AI development. In Q2, 170 out of the 1,006 funds tracked by Insider Monkey held a stake in Broadcom, a slight drop from 163 out of 1,022 funds in Q1, with notable exits including Third Point and Two Sigma Advisors, and the stock trades at a forward P/E ratio of 18 versus NVIDIA's 23.42.

Nvidia has committed at least $6.5 billion to photonics companies over the three months prior to May 2026, including $500 million to Corning for advanced optical connectivity solutions and $2 billion each to Lumentum, Coherent and Marvell, according to CNBC. The impact has been significant, with Marvell shares gaining 183.4% year to date, while Lumentum, Corning and Coherent have advanced 142.5%, 68.8% and 60.3%, respectively. Goldman Sachs projects the total addressable market for optical networking to grow from roughly $15 billion in 2026 to about $154 billion by 2028, a more than ninefold increase. Adoption of co-packaged optics is expected to accelerate starting in 2027, reaching roughly 20% to 30% penetration by 2028, while Mordor Intelligence estimates the global photonics market will reach $1.46 trillion by the end of 2026. Investors seeking diversified exposure can consider the Roundhill Photonics & Optics ETF LYTE, with $254.2 million in assets under management across 19 holdings; the KraneShares Photonic and Optical ETF LUMA, with $9.76 million in net assets; and the Tema Photonics & Optical ETF LAZR, with $94 million in net assets across 27 companies.
