To The Moon

The Short Version

I think $Marvell Technology(MRVL)$ is a fundamentally solid company, and the stock is pulling back into my long-term buy zone.

Marvell designs the chips that move data around inside AI data centers, plus custom AI chips for Amazon, Microsoft and Google. It's growing fast, has produced positive free cash flow every year for a decade, and Morningstar thinks it's worth $326 a share.

The stock closed at $133.55 on November 5, about 60% below its high, after Marvell agreed to buy Lumentum in an all-stock deal Morningstar thinks is overpriced. The big risk: Marvell's results ride on AI data center spending.

1. How Marvell Makes Money

Marvell designs chips but doesn't manufacture them. Think of an architect: Marvell draws the blueprint, an outside factory builds it, and Marvell sells the finished chip.

Morningstar sees Marvell as the clear leader in optical chips, the ones that keep data moving between servers at very high speed. Most of the business now comes from data centers, and customers spending over $100 million a year grew from 13 in 2020 to 19 today.

Why it matters: Marvell wins multi-year spots inside the biggest AI buildouts, then gets paid every time those customers buy more.

2. Economic Moat

Marvell has a real moat. Morningstar rates it "narrow," and I agree.

A moat is whatever stops competitors from taking your customers. "Narrow" means Morningstar expects above-average returns for at least 10 years.

Bottom line: the moat is real, but narrower than the giants Marvell competes with.

3. Growth Opportunities

Two AI engines drive Marvell's growth: custom chips and optical connections.

• Custom AI chips. Management expects this business to double in fiscal 2028, then double again to about $10 billion in fiscal 2029.

• The Google deal. Signed in August 2026. Google gets warrants for up to 7% of Marvell's shares if it spends $120 billion with Marvell through fiscal 2033.

• Optical connections. Morningstar expects about 60% growth a year for five years. The Celestial AI acquisition adds co-packaged optics, which puts the fiber link right next to the chip.

• Lumentum. Adds the lasers that sit next to Marvell's chips. The deal is expected to close in early 2028.

• Big targets. Management is aiming for $70 billion to $90 billion in revenue by fiscal 2031 (roughly calendar 2030), up from $8.2 billion in calendar 2025.

4. Risks and Weaknesses

The biggest risk is that Marvell's results ride on one thing: how much the cloud giants keep spending on AI.

1. AI spending could slow. Morningstar flags that big AI labs like OpenAI and Anthropic still lose money, which makes their spending less certain.

2. Overpaying for Lumentum. Morningstar estimates Marvell is paying more than double what Lumentum is worth, and cut Marvell's fair value from $360 to $326 because of it.

3. Dilution. The all-stock deal and the Google warrants both create new shares, so each existing share owns a smaller slice of the pizza.

4. Much bigger rivals. Broadcom and Nvidia can outspend Marvell on research.

5. A few customers matter a lot. Losing one big custom chip customer would hurt.

6. Geopolitics. AI chips can get caught in US–China restrictions.

7. Wild price swings. Over the past year the stock traded between $70.69 and $329.88.

What to watch: the next earnings report, any change to the Lumentum deal, and what the cloud giants say about AI spending.

5. Financial Health

I think Marvell is financially healthy: growing fast, producing real cash and carrying manageable debt.

Marvell's fiscal year ends in late January, so fiscal 2026 is basically calendar 2025.

Revenue

Revenue grew 42% in fiscal 2026 to $8.2 billion. Morningstar's forecast assumes the AI buildout keeps going for five more years. If it doesn't, most of those dashed bars never get built.

Profits and cash flow

Marvell reports two kinds of profit. Official (GAAP) profit follows strict accounting rules and counts costs like writing off the value of acquired technology. Adjusted profit strips those out. When the two disagree, cash flow is the tiebreaker.

In fiscal 2024 and 2025, Marvell posted official losses but still produced $1.41 billion and $1.58 billion of free cash flow. Those losses were mostly accounting charges, not a business burning money. Official operating margin turned positive at 16% in fiscal 2026, and Morningstar sees it reaching 39% by fiscal 2031.

Debt vs cash

Marvell has about $1.5 billion of net debt, less than one year of free cash flow. The bigger number is $16.5 billion of goodwill and intangibles, the premium paid for past acquisitions. If a deal disappoints, that value can be written down, and Lumentum would likely push it much higher.

Valuation

Morningstar sees all three as undervalued, with Marvell the cheapest. On Morningstar's forecasts, $133.55 is about 16 times fiscal 2028 adjusted earnings. That's cheap if the growth shows up, and expensive if it doesn't.

6. Smart Money Framework

Marvell is pulling back into my long-term institutional buy zone, where I can start building a long-term position at a discount.

The optimal long-term entry is $112 to $120, the long-term Smart Money Zone. The stock closed at $133.55 on November 5, about 11% above it.

What I expect: 70% of the time, price recovers back to its all-time high within one to two years from a zone like this. Here, that's about $330. That also means roughly 3 times in 10 it doesn't, so position size matters.

The fast lane: a volume profile shows how many shares traded at each price. Thin areas are a fast lane, or speed lane: little stands in the way, so price can slide through quickly. MRVL still has a fast lane down to $100, worst case.

The conservative entry: if I wanted to be as conservative as possible, I'd wait for $100, where a huge block of about 1 billion shares sits as support, with another at $90. The tradeoff is that price could bounce early and I'd miss the move.

Where the chart and the fundamentals agree: Morningstar's $326 fair value sits almost exactly at the old high of about $330. Both point to the same place.

Bull Case vs Bear Case

Bulls say the market is pricing in the end of the AI boom while Marvell's customers sign multibillion-dollar deals. Bears say Marvell is the small player in an arms race, overpaying for Lumentum with its own stock.

The Verdict: Is Marvell Fundamentally Solid?

Yes. I think Marvell is a fundamentally solid company, with real AI-cycle risk and a deal that looks too expensive.
