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 

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 

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 

The photonics-as-AI-bottleneck claim has faded, leaving Lumentum facing more pain before the theme recovers. A large December options node sits at $600; the stock bot targets downside at $650 and $595, with $581 a possible liquidity sweep where smart money would buy instead of rushing in at $650 or $630. Most photonics companies will likely never come back. x.com 

Lumentum looks only slightly attractive, and only after another 10% drop, at about 24.5 times its guided $40 FY28 EPS at $980. Its upside is almost entirely driven by optical circuit switch demand from lead customer Google, which also points to a great 2027-2028 for fellow Google OCS supplier Huber+Suhner. Total OCS demand now exceeds the 8 million units first cited. x.com 

Lumentum's optics business is too valuable to sell for less than $2,000 a share, making a rumored Marvell takeover implausible. Lumentum is worth at least $2,000 a share now; a $120 billion purchase would consume about 60% of Marvell's roughly $200 billion market value, while a fair price would be closer to $160 billion in this view. x.com  x.com  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 

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 

Rising 1.6T switching demand favors optical suppliers, though their execution risks vary. Bank of America says the market could grow ~101% annually through 2030. Marvell's leading DSPs and Lumentum's supply-short 200G EML lasers are lowest risk; Applied Optoelectronics' capacity expansion and Fabrinet's customer concentration make them medium risk. Aeluma remains pre-commercial, while Lightwave Logic's polymer modulators are a high-risk moonshot despite its TSM partnership. x.com 

Applied Optoelectronics' laser capacity could be worth much more if Marvell pays over $100B for Lumentum. That price would show how valuable laser capacity is and, in that scenario, AAOI could reach $200 within a quarter or two. The deal is only a rumor, and its price is unknown. x.com
