X-FAB's celebrated AI capacity expansion means very little for shareholders today: no new revenue, no new customer and no meaningful earnings before 2029. It is merely the formal handover of a €127 million subsidy approved in late 2025, a normal 30-40% rate, and X-FAB must still fund most of the investment. The cleanroom will not produce until late 2028 and mainly serves its legacy automotive, smartphone and medical markets, making it one of the least exciting AI-linked stocks fundamentally. … Show more

X-FAB is a mediocre foundry trading at more than 70 times forward earnings while making bottom-of-the-barrel gross margins and burning cash for almost its entire history. Traders buying it for Nvidia exposure could own Nvidia itself at 20 times earnings. x.com 

X-FAB's earnings confirmed direct exposure to co-packaged optics and the 800V shift, which should drive a re-rating as markets price growth ahead. Management said it is progressing in CPO, with three silicon photonics projects and photonics volume production expected in 2028, a timeline not in revenue models yet. The 800V transition supports SiC and GaN demand, with three new SiC data center design wins pointing to a 2027 ramp. Current revenue is unimpressive, so some waiting is needed. x.com  … Show more

X-FAB is not a strong long-term investment because legacy automotive drag and high operating costs are too heavy for a big pivot or soaring profits in the next few years. It is a relatively stable, revenue-generating company, but it rarely delivers anything groundbreaking. It works only as a short-term swing trade, riding occasional hype or liquidity pumps such as @aleabitoreddit's interest. x.com 

Coherent now has credible exposure to almost every optical architecture hyperscalers are exploring, and its Nvidia deal materially de-risks that roadmap. Nvidia's nonexclusive pact adds a multibillion-dollar purchase commitment, a $2B equity investment and access to five CPO product families. First CPO/NPO revenue targeted for H2 2026 matches Nvidia's timing. Data center and communications are already 72% of revenue. Qualification, standards, concentration and margins remain unsettled. x.com 

X-FAB Silicon Foundries' exposure to co-packaged optics and 800V power is now confirmed, but it is a 2028 patience trade rather than a near-term catalyst. Per @aleabitoreddit's earnings-call recap, X-FAB said it is making progress in CPO and expects the 800V transition to support SiC and GaN demand. Photonics volume production and the new Erfurt fab both land at the end of 2028, and wide-bandgap revenue dipped 30% quarter on quarter on one customer's timing. x.com 

The LYTE ETF offers pure-play exposure to global photonics and optics leaders, with Coherent and Lumentum as its top holdings. Nvidia CEO Jensen Huang has said the world needs substantially more silicon photonics capacity than it has today, explaining Nvidia's $4B investment in Lumentum and Coherent. x.com  x.com 

Credo looks exposed as networking becomes AI's next bottleneck and Nvidia locks down optical fiber for scale-up, scale-out and scale-across links. MicroLED is readily available and a good contender for scale-up and potentially scale-out, with many Asian suppliers pivoting into it. x.com  x.com 

X-FAB is a pure-play silicon carbide and gallium nitride foundry, reminiscent of an early Tower Semiconductor or Soitec. Per @aleabitoreddit, NIST filings name it the only high-volume SiC foundry in America, making it critical infrastructure as NVIDIA pushes 800 VDC and power-chip peers Navitas and Wolfspeed rerate hard. It is also in CHIPS Act 2 blueprints for photonics, with Nokia and NVIDIA evaluations underway and volume production expected in H1 2028, all at a $1.5B market cap. x.com 

GlobalFoundries' Xanadu partnership strengthens its position as a shared quantum-manufacturing platform across architectures. Its Malta fab will develop ultra-low-loss SiN photonics and superconducting nanowire detectors, alongside up to $375M in US quantum R&D funding. It ranked first of 23 companies in the earlier quantum map; production volumes and revenue remain undisclosed, with process transfer and yield validation still ahead. x.com
