Aixtron's faster reactor shipments should lift Nynomic's LayTec revenue in H2 2026, not just 2027. Aixtron's Q3 revenue rose 54%, with Q4 guided higher; LayTec metrology is standard on its optoelectronics and power tools. The slower switch to 6-inch InP wafers means more reactors per chip volume. Aixtron expects the early-stage demand cycle to last until 2030. Framework-agreement call-offs leave much of this demand out of Nynomic's backlog; its estimated 2026 EV/sales is about 1.44x. 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 

Nynomic's AI photonics appeal is diluted by its holding-company structure, and after a 91% six-month run the asymmetry is gone. Its LayTec unit has a near-monopoly in indium phosphide reactor metrology, per NuWays, but is only 15-25% of revenue; FY25 group revenue fell 10%. Even if LayTec triples in three years, group growth is about 17% a year. A re-rate needs a LayTec sale, separate disclosure or a narrative shift; at about €21, near analyst targets, wait for a pullback or size small. x.com  … Show more

Lumentum stands to gain as the shift from copper to light inside AI data centers accelerates. Co-packaged optics is now in mass production, per TrendForce, with Nvidia shipping Spectrum-X CPO switches. Near-packaged optics is catching on fast; Lumentum CEO Michael Hurlston says its demand looks bigger than CPO's and came sooner, now late 2027 or early 2028. He sees about $40 a share of fiscal 2028 earnings power, above Street estimates, with none of CPO or NPO in the numbers yet. 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 

Nynomic's revenue is not reflecting its customers' hard expansion of MOCVD capex, which should flow through to it, so something is probably wrong with the thesis. Either it is broken or the revenue is about to hit hard, and the former looks more likely. Plan Optik's flat revenue is different: Lumentum is growing through pluggables, not the co-packaged optics where Plan Optik plays, so its timing is more 2027–2028. x.com 

Lumentum's valuation is supported by Nvidia's co-packaged optics scale-out progressing faster than expected. Spectrum-X CPO switches are in mass production on better component yields, with shipments forecast at 15k in 4Q26 rising to 100k in 2027. CPO and NPO are seen contributing 12% and 26% of Lumentum's revenue in 2027 and 2028. Scale-up optical engine estimates were revised to 6.5m and 42m for 2027 and 2028, with full NPO adoption for the cycle retained. x.com 

Nynomic's re-rating case is much stronger at about 0.6x EV/sales and 0.5x book after AIXTRON's results. AIXTRON's optoelectronics orders, over 65% of €171M of intake, and its €359M backlog translate directly into revenue for Nynomic's LayTec unit in H2 2026 and early 2027 with near-zero execution risk. That makes Nynomic's conservative March guidance a floor and opens upside for its semi segment from a historical ~€92M trough toward a €110M+ run rate at expanding margins. x.com 

The shift from copper to light inside AI data centers is accelerating, and near-packaged optics is pulling optical demand forward. Lumentum's CEO said NPO demand looks bigger than CPO and arrived sooner, and he sees about $40 per share of fiscal 2028 earnings power, above sell-side estimates, with none of it in the numbers yet. Coherent's CEO said CPO and NPO engagement has jumped, with comparable content per socket. NVIDIA has moved its Spectrum-X CPO switch into full production. 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
