Marvell's management will squander all the engineering talent in this deal, making it deeply unattractive. 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 

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 ambitious long-range outlook is encouraging about hyperscaler and AI-lab spending plans, but hitting it depends on AI revenue and token consumption soaring through decade's end. Even if its FY28 estimates rise again, Marvell trades at a healthy premium to Nvidia and Broadcom, especially on a GAAP basis, and those two are growing fast too. x.com 

Lumentum's 109% year-on-year growth and sold-out capacity through 2029 make selling its AI optics exposure questionable. Bloomberg reported Marvell is in advanced talks to buy it; the appeal depends on the price, especially when holders of an $80 billion Lumentum would become holders of a $320 billion-plus Marvell growing 37%. 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's strong quarter was already priced in, so a sell-the-news decline is likelier. Q2 revenue rose 37% to $2.739B, data center revenue 46%, and Q3 guidance of $3.15B beat estimates; management sees custom silicon revenue more than doubling in FY28 and a path to about $18B of FY28 revenue. But the Google partnership and AI growth were largely traded ahead, and the stock never broke its rising channel's top. Long term, it is still a good company to add to at better prices before the midterms. … Show more

River Eletec's speculative AI/HPC-adjacent technology looks worth more than its $38 million market cap. Its low-jitter 1.6T product may be sampled by Marvell, though that is a guess; past earnings have been disastrous. x.com  x.com 

The Lumentum merger makes Marvell's path toward a $1 trillion valuation look clearer if it executes well. Jensen Huang had called Marvell the next $1 trillion company. Lumentum's demand is sold for the next two to three years, though whether that gives Marvell an edge remains an open question. Marvell looks like a long-term opportunity, but the route to building a position is still unclear. x.com 

Marvell wasted the AI boom and leadership's handling raises doubts. During last summer's bull run, when demand across the AI buildout was higher than ever, it still missed earnings and its CEO said they didn't know whether the demand was real. The stock fell 10-15% immediately and kept bleeding toward its April tariff-crash lows. x.com
