Lumentum and Coherent may be worth buying because Nvidia has just invested $2 billion in each. x.com

Tighter Lumentum laser allocations would strengthen Coherent's pricing power if Marvell's rumored acquisition leads it to prioritize Nvidia and its own modules. Other buyers would face tighter supply, and hyperscalers would push harder to second-source lasers from Coherent. 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
Co-packaged optics standards could make finished transceiver modules smaller and more interchangeable as chip designers build optical engines inside their packages. That is another reason to avoid Lumentum, Coherent and Applied Optoelectronics and prefer Soitec. Lumentum and Coherent now earn a lot from finished modules, leaving them exposed if the architecture changes. x.com
Marvell’s acquisition of Lumentum secures the laser supply its scale-up optics and Celestial’s most advanced silicon-photonics memory-pooling solution require. Nvidia had bought all of Lumentum’s capacity, leaving Marvell unable to provide scale-up optics in its ASIC program. Owning that supply and the IP could give Marvell an advantage over larger accelerator rivals and help it conquer AI accelerators via optics over the long term, despite existing contracts. x.com x.com x.com
Seven Lumentum directors buying over $1.1M of shares signals insider confidence in its role in the AI buildout. Lumentum's optical and photonic technologies are used in high-speed networks and data centers, positioning it directly in AI infrastructure beyond GPUs. NVIDIA has also invested $2 billion in Lumentum, and photonics looks like the next leg of the buildout. x.com x.com x.com
Applied Optoelectronics, Lumentum and Coherent face share losses at US hyperscalers to Innolight. Channel checks favor Innolight gaining share in Q2 2026, at the expense of those three. Per @poezhao0605, a $7B Hong Kong IPO, the largest in years and upsized from $5B on strong demand, has cleared its listing hearing. x.com
A buyout would devalue Lumentum's work and be the worst outcome for shareholders when demand and investor interest are strong. Lumentum has been exceeding demand requirements and doing exceptionally well on its own, so it is better off independent; if the rumors are rejected, its rally should continue higher. 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
Coherent and Lumentum are ultra overvalued, so when their monthly top comes in, they should fall about four times faster than they rose. Coherent may have already topped. x.com
Copying Nvidia's investments in Lumentum, Coherent, Nokia, Intel and Nebius is a strong strategy, because Nvidia vets companies on technical and commercial merit, funds them in the billions and then awards them large design and supply contracts. x.com x.com
