Marvell's $70-90 billion FY31 revenue target looks credible: COO Chris Koopmans said key foundry, substrate and packaging suppliers get five-year forecasts and had already seen it before investor day. A $500 price target still looks too aggressive for now; Marvell must show it can grow its networking and photonics segment to deserve a safe price increase. x.com  x.com 

The market may still be underestimating Marvell as it becomes a key supplier of custom silicon and connectivity for the AI build-out. At its Investor Day, Marvell put its addressable market at about $400 billion by 2030, targeted about $20B of FY28 revenue and said revenue could reach $70-90B by FY31. Last quarter revenue rose 37% to $2.74B on AI and data-center demand, and Nvidia's Jensen Huang reportedly called Marvell the next trillion-dollar company. x.com  x.com 

Marvell's potential Lumentum acquisition may fail to increase per-share value because the added profits may not cover dilution and financing costs. A simplified calculation using reported market values implies roughly 38%-45% more shares, requiring about 45% more combined net profit to preserve EPS; debt would add interest and repayment pressure. If the price already reflects future growth, a control premium and possible customer concerns add risk. x.com 

Marvell looks interesting at less than 30x calendar-2027 EPS against expected 60-70% annual EPS growth, but overpaying for Lumentum could drive its shares lower. Marvell could pay up to $110B, roughly a 30% premium; the stock-versus-debt mix is unclear, and Lumentum holders might own a third of the combined company. If the deal falls apart, Marvell could rise 10-12%. x.com 

Marvell is a 2030 stock: the market sold it 32% off its high because the payoff starts in 2029. Data center is 79% of revenue and growing 46%. Management raised its fiscal 2028 target to $18B, said custom silicon more than doubles next year, and in August signed a Google TPU agreement with up to $120B of revenue potential over six years. x.com 

Marvell's $1 trillion valuation, which Jensen Huang predicted, is a slogan rather than a valuation. At its FY2028 targets of $16.5B revenue and a high-30s operating margin, $1T means about 60x sales and 180x adjusted earnings; at 30x earnings it would need roughly $95B of revenue, essentially the entire $94B 2028 data center market Marvell estimates. GAAP net income was just $34.5M in Q1, and dilution adds pressure. Operating leverage from 45% growth is the bull case. x.com 

Marvell expects its revenue to grow tenfold in five years to $80B, driven by custom chips it builds for hyperscalers. Those companies design their own chips to reduce reliance on Nvidia and cut the long-term cost of off-the-shelf parts. The custom segment had no revenue two years ago and is expected to bring in $30B by 2031. x.com 

Marvell is easily the stock pick for the next decade. x.com 

A possible Lumentum deal could dilute Marvell's shares and add enough debt to cut forecast 2027-28 EPS by at least 20%. A 70% stock structure would require about 360M new shares and $32B in debt; a 50/50 structure, about 275M shares and $57B in debt. A higher multiple from today's 45x looks unlikely to offset the hit soon. The next year could be difficult, even if the deal proves very bullish from 2028 onward. x.com 

Owning Lumentum's laser fab could secure Marvell's FY28 supply and hedge its DSP franchise as optical links shift to CPO. The rumored deal's strategy makes sense, but short-term pain is likely: at a 30% premium, roughly $17.5B in new debt and the rest in stock, rough math puts EPS dilution near 15%. It turns accretive only if Lumentum outgrows Marvell at today's guided rates for five or six more quarters, which looks achievable while the laser shortage lasts. x.com  x.com  x.com
