Marvell Technology (NASDAQ:MRVL) trades at $196.40, and its long-term case for three-to-five-year holders beefs up because a acquisition of Lumentum (NASDAQ:LITE) would add to its AI optics roadmap. Shares fell 10.05% in one session and 14.05% over the past week on reports of Marvell’s interest.

Marvell designs custom AI chips, optical DSPs and switches for hyperscalers. Its Data Center revenue reached $2.17 billion last quarter, or 79% of sales. Lumentum makes the lasers and optical switches that link AI clusters, and its revenue grew 109.3% in its latest quarter. Lumentum’s market cap is roughly $76.2 billion and Marvell’s is $172.2 billion, so a deal would be a heavy lift.
Raised Guidance and a Lower Multiple Reframe Marvell’s Selloff
Marvell trades at 26x forward earnings versus 65x trailing, with a PEG ratio of 0.484. Management raised its fiscal 2027 revenue outlook to roughly $12 billion and fiscal 2028 to approximately $18 billion. It also expects custom revenue to more than double in fiscal 2028. On the Alphabet (NASDAQ:GOOGL) Google warrant, management said, “Whatever you’ve modeled previously for custom numbers prior to the warrant definitely goes higher.”

Why Didn’t MRVL Make The Top 10 List?
24/7 Wall St has helped investors make money for over two decades, and our top analysts just finished ranking the definitive Top 10 Stocks To Buy Now. Not the ten biggest companies. Not the ten everyone is arguing about. The ten best stocks to buy right now.
And MRVL didn’t make the cut!
The report is free, and you can see why we think each stock is a top investment today.
Lumentum fills a gap in that plan. Marvell said its scale-up optics expectations for next year increased meaningfully, and Lumentum sees NPO and CPO ramping around 2028. Having Lumentum’s lasers would pair Celestial AI’s photonic fabric with in-house light sources. No analyst rates Marvell a Sell.
A Premium Price for Lumentum Could Dilute Marvell’s AI Upside
Lumentum trades at 25.27x sales and 43x forward earnings, a higher valuation than Marvell’s 18.68x sales. Paying a acquisition premium would take new stock or debt on top of $4.96 billion in existing debt, a $2 billion preferred raise and a Google warrant for up to 7% of shares.
Concentration adds to the risk. A handful of hyperscalers drive Data Center sales. The custom ramp is squeezing gross margin mix, and Marvell is still integrating Celestial AI and XConn. With a beta of 2.26, the stock can swing hard on any deal headline.
Deal Terms and Fiscal Third-Quarter Results Will Settle the Debate
Marvell has issued no statement, so investors are pricing a rumor. The deal terms, including cash versus stock and the size of the premium, will decide whether it adds to earnings. Meanwhile, Marvell has beaten revenue and EPS estimates in each of the last three quarters.
The next checkpoint is the fiscal third-quarter report, measured against guidance of $3.15 billion in revenue and $1.10 in non-GAAP EPS. After that, management expects to reach its 38% to 40% operating margin target in fiscal Q4. Disciplined deal terms would beefs up the bull case. A stock-heavy premium would hurt it.
Analysts See Big Upside After Marvell’s Steep Monthly Slide
Marvell trades at $196.40 against a consensus target of $340.56, which implies 73.4% upside. Targets are estimates and can fall quickly. The 46 analysts covering the stock break down as follows:
Strong Buy: 8
Buy: 32
Hold: 6
Sell or Strong Sell: 0
Marvell is up 131.5% year to date versus 10.82% for the S&P 500. Over the past month, Marvell fell 25.65% while the S&P 500 slipped 0.91%. That leaves shares well below their 52-week high of $329.73.
Having the Optical Stack Could Pay Off for Marvell Through Fiscal 2029
At $196.40, Marvell’s valuation leaves room for its AI roadmap to drive results.
Growth depends on custom silicon and scale-up optics (we highlighted seven suppliers behind the AI data-center expansion, from power to cooling to networking, in a free report you can grab here). Management called fiscal 2029 custom revenue a $10 billion-plus opportunity with “a lot of upside bias”. Both companies expect NPO and CPO adoption to take off around 2028. Lumentum’s lasers and optical circuit switches would let Marvell supply both ends of those links.
At 26x forward earnings, the share price reflects fears about the deal and gives little credit to the $18 billion fiscal 2028 outlook. Lumentum guided to a 39.5% to 40.5% non-GAAP operating margin, above Marvell’s 36.6%. That could lift a combined company’s margins if deal costs stay contained.
The thesis breaks if Marvell overpays with heavy stock issue, if data center growth stalls or if hyperscalers bring optics in-house. Watch the deal terms, the next earnings report and gross margin over the next two quarters.
At $196.40, the share price reflects a rumor-driven discount to Marvell’s fiscal 2028 outlook, and a Lumentum deal could expand its optics capabilities over a three-to-five-year horizon.

Tech stocks aren’t getting shredded for any old reason. It’s actually very fundamental: Free cash flow is drying up for Big Tech leaders, and capex is rising dramatically. Investors are questioning whether this ratio is totally out of whack, given more realistic growth projections for AI. The combined capex of Amazon, Alphabet, Meta and Microsoft
So far, 2026 has been a solid year for stock market investors, with the benchmark S&P 500 (^GSPC +1.04%) up around 11% year to date.

Nvidia (NASDAQ: NVDA) has been a market-average stock this year, rising about 15.5% versus 13% for the S&P 500. Investors are used to huge outperformance, and this year hasn’t delivered that.

For four years now, the stock market has been on a massive bull run. Since bottoming out in October 2022, the S&P 500 (^GSPC -1.82%) has soared, fueled in no small part by enormous gains in stocks connected to artificial intelligence (AI). But with stock valuations approaching very extreme levels, investors have good reason to

The S&P 500 (SNPINDEX:^GSPC) has risen around 11% this year as I write. And by one valuation gauge with data going back to 1871, investors have rarely paid more for it.
