Given the dynamics, investors must be wondering if it’s the right time to invest, retain or sell the stock. Let’s discuss the fundamentals of the company to get a better insight.

 

MRVL Stock Faces a Temporary Setback Amid Long-Term AI Growth

The decline in MRVL's stock price has come amid a broader sell-off in AI-related stocks spanning hyperscalers, semiconductor companies and AI infrastructure providers, as investors increasingly question whether massive AI investments will generate sufficient returns. Since MRVL supplies its solutions to these infrastructure providers, MRVL’s stock has also been affected.

Marvell’s recent stock decline coincides with the announcement of its proposed $115 billion acquisition of Lumentum Holdings (LITE - Free Report) . Under the terms of the all-stock deal, Lumentum stockholders will receive a fixed exchange ratio of 4.5 shares of Marvell common stock for each Lumentum share held, raising investor concerns over valuation, shareholder dilution and the transaction’s potential impact on earnings.

However, in the long term, the acquisition of Lumentum will add a substantial portfolio of optical and photonic technologies used in AI data centers, cloud infrastructure, telecommunications networks and advanced manufacturing. Lumentum’s Optical Circuit Switching, high-speed transceivers and laser components are of the most strategic importance for MRVL.

Marvell’s accelerating AI-driven growth provides a favorable backdrop for its proposed acquisition of Lumentum. Marvell’s second-quarter fiscal 2027 revenues increased 37% year over year to $2.74 billion, led by a 46% increase in data-center revenues to $2.17 billion, which accounted for 79% of total sales. Management raised its fiscal 2027 revenue growth outlook to approximately 45%, or roughly $12 billion, while expecting data-center revenues to increase about 60%, up from its prior expectation of approximately 50%.

Within Marvell’s portfolio, custom silicon is emerging as an increasingly important growth driver as hyperscalers expand their demand for specialized XPUs and XPU-attach products. AI connectivity also remains strong, with demand for 800G optical DSPs continuing and 1.6T products ramping rapidly. Marvell’s scale-out switching business is on track to more than double in fiscal 2027, driven by growing adoption of 51.2T switches across a broader customer base. Meanwhile, increasing customer interest in scale-up optics and switching solutions could provide additional growth opportunities as AI infrastructure architectures evolve.

MRVL to Benefit From a Broader Portfolio

The integration of MRVL’s electrical and optical interconnect, switching and custom silicon technologies with Lumentum’s high-performance lasers, optical transceivers and optical circuit switching capabilities is expected to create a comprehensive connectivity portfolio spanning scale-across, scale-out, scale-up and scale-in architectures. These factors will strengthen MRVL’s competitive positioning relative to Broadcom (AVGO - Free Report) and enhance its ability to compete with Coherent (COHR - Free Report) .

Broadcom is a leader in the domain of custom silicon solutions for data centers. Broadcom’s advanced 3.5D XDSiP packaging platform is critical to ensure the performance and efficiency of custom AI XPUs. Combining Marvell's custom silicon, switching and DSP technologies with Lumentum's lasers, transceivers and optical switching could help MRVL compete with Broadcom's integrated AI connectivity portfolio.

Coherent is a vertically integrated manufacturer of lasers, transceivers, optoelectronic devices and modules and engineered materials that serve communications, industrial, instrumentation and electronics markets. Lumentum's optical components and laser technologies would strengthen MRVL's optical portfolio, enabling it to compete more effectively with Coherent in high-performance lasers and optical connectivity.

Amid these developments, investors need to keep a close eye on Marvell’s ability to translate the acquisition of Lumentum into meaningful competitive gains. MRVL’s profitability remains sensitive to product mix as newer data center platforms ramp up. The Zacks Consensus Estimate for MRVL’s fiscal 2027 earnings is pegged at $4.21 per share, implying year-over-year growth of 48%. Estimates have remained unchanged for the past 30 days.

Conclusion

The recent decline in Marvell’s stock price may present an opportunity for investors seeking exposure to the expanding AI infrastructure market. MRVL’s strengths in custom silicon, optical connectivity, switching and data-center interconnect, along with its proposed acquisition of Lumentum, could support its long-term growth prospects.

However, the proposed acquisition also introduces integration, shareholder dilution and execution risks. Investors should closely monitor the transaction’s progress, MRVL’s profitability trends and the company’s ability to translate its expanding portfolio into sustainable earnings growth.

Currently, MRVL stock carries a Zacks Rank #2 (Buy). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
