Rapid revenue growth against forward valuations makes Nvidia and Micron additional calculated risks after the selloff, alongside Meta, Broadcom, IREN, Vistra, Nokia and Oracle. Nvidia grew revenue 106% and guides Q3 to $108B, plus or minus 2%, at 17.5x forward earnings; Micron grew revenue 379% to $54.2B, guides $61.5B next quarter and trades at 5x. The other six retain their growth, contracted-demand or customer-order cases. x.com 

If Micron has only two years of decent forecasts, its limited visibility warrants a lower multiple, not a higher one. x.com 

Networking, power and compute look more durable than cyclical memory in the AI buildout. Lumentum's revenue compounded year after year across the 2010s and 2020s, unlike Micron's; AWS revenue also compounded. Lumentum, Nebius, Bloom Energy and Credo should heavily outperform SanDisk and Micron from here, though AI itself remains heavily doubted. x.com  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 

Lumentum requires paying up heavily for a company that is not yet making money. Revenue grew 109% year over year, but it trades at about 25 times annualized sales, and it is growing less than memory makers at ten times their valuation. @ZeekTyt cites Lumentum's CEO expecting to supply only about 30% of requested laser demand as CPO and NPO ramp in 2027, with balance around 2029-30. x.com  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 

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 

Marvell risks paying a peak-scarcity price for Lumentum if optical supply catches up by 2028-30. The proposed ~$99B deal values Lumentum at roughly 20x guided annualized revenue and 58x estimated after-tax operating income, while Lumentum, Coherent and Chinese suppliers are adding laser capacity. The DSP-and-laser combination has strategic logic, but durable scarcity economics and Nvidia's response remain uncertain. x.com 

AI bandwidth demand still favors Coherent and Lumentum, but tight customer financing can delay orders and lasting valuations need durable profits. A model provider losing share need not reduce total bandwidth use. Coherent could beat and raise guidance; Lumentum may only meet estimates this quarter, improving next quarter. If margins partly reflect scarce indium phosphide, added supply will test whether upgrades, volume and cost gains sustain earnings. These earnings calls remain forecasts. … Show more

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
