Ignored the clearer irrelevant stuff like $POET that people mentioned tho. There's like 500 comments, but I guess X limits everything I can see. We'll see how your highest conviction ideas do.

The difference between NASDAQ and EU listing: $POET: $2.4B MC -> Packages Sivers lasers -> One $50m pre-production contract for warrants > $XFAB: $1.7B MC ->SiC/GaN/MEMS/Silicon Photonics Foundry backed with EU CHIPS ACT, US CHIPS ACT PMT -> Below replacement P/B value -> $NVDA, $NOK direct eval of their pre-commercial SiPH foundry, volume ramping 2027/2028 -> $XFAB leading high-volume scaling of Europe's photonic supply chains as the foundry, with IMEC/CEA-Leti, Ligentec, Smart photonics, PHIX Photonics, Luceda Photonics, and Europe's photonic players under it. -> Leading customers like $NVTS, $POWI, Lite-On -> US from Dpt. of Commerce: "the only high-volume SiC foundry in the U.S."

Just some mobile shower thoughts around $XFAB and train of thought: 1. 800vdc $NVDA push look for GaN/SiC players / power semis. 2. $NVTS and other fabless/fab-lite beneficiaries of $NVDA push probably use foundry models 3. care more about Western supply chains over Asia, want to build up Western capabilities + Western premiums. 4 China has a lot of capacity, maybe risk into 2028, but again it’s building up Western supply chains 5. XFAB only high volume SiC foundry in America (others like $ON or Infineon are vertically integrated) 6. advanced 6in SiC, 8in GaN on Si, building out 8in GaN 7. Maybe likely they’re developing 8in SiC from CHIPS backing, just not public material 8. check SiC revenue -> 152% Y/Y growth okay. Probably something markets missed, since blended looks worse from automotive slump, that should come out recovery 9. $NVTS and others turns out to use $XFAB. $POWI cites $XFAB in filings, among others. 10. both are $NVDA power semi explicit partners, great exposure indicator to 800vdc power semi players. 11. US Dpt. of commerce cites $XFAB as only high volume SiC foundry in the US, $50M PMT 12. validation from US Gov about critical component in supply chains is amazing 13. EU CHIPS Act gives $XFAB $128M EU, for foundry (MEMS, AI, etc), okay turns out they’re critical MEMS player 14. So that’s validation from EU gov about critical component in supply chains, dual continent subsidies 15. So now we know $XFAB is a critical MEMS foundry so you get SiC capabilities, GaN development, and MEMS upside 16. they also got $47.6M EU funding for leading Silicon Photonics supply chain in EU. So that’s EU funding on multiple angles. 17. Turns out, I know all the players there from smartphotonics from $GFS deck. 18. $NVDA and $NOK are qualifying them for silicon photonics HVM. I think this is just a government backing angle for success in EU photonics so likely to succeed… kinda like how Us gov encourages everyone to use $INTC. 19. Okay chips act 2 is coming out next week… so they’ll probably get funding there or more revenue commitments 20. 1.28 p/b, now that’s probably just book cost? Likely coming out of $SOI type legacy drag cycle. 21. Did some modeling around actually replacement values, true replacement p/b cost likely ~.5/.7. 22. Getting business for free, while having upside from SiC near term into Silicon Photonics / GaN as main growth past H2 2027. Thoughts: derisked by p/b values + replacement value. maybe like 20% downside from macro. However, critical dual continent importance. So downside risk seems low, but upside is compelling. Lot of capex likely backstopped by upcoming chips act catalyst + national security concerns. Maybe 2.5-4x rerating seems possible/likely. Not a 10-20x, but recovery from depressed valuations from silicon photonics upside with SiC / GaN bridge. TLDR: likely trading lower than replacement value, dual continent subsidies likely subsidize capex. Gov grants shows importance to Western supply chains, photonics longer term upside, SiC/GaN demand likely near term upside and bridge. Don’t control any recent volatility, should shake out anyone not really confident in the thesis though. CHIPS act 2 from EU is coming up, $XFAB was listed in earlier blueprints for optical ecosystem, so should get a boost after that comes out as near term event catalysts. So now is the risk reward seems compelling, we’ll see if this is right or not

I genuinely think $XFAB is very compelling at $1.5B MC, despite recent volatility. Per NIST filings stated they were the only high volume SiC foundry in America. Making them extremely “critical infrastructure”… Verbatim from the US Gov. And they’re the first comprehensive pure play foundry for SiC/GaN. So it’s very compelling exposure as $NVDA pushes 800 VDC and as other power semi players from $NVTS and $WOLF are all re-rating hard. For long term photonics exposure: They were literally listed in CHIPS Act 2 blueprints… with $NOK / $NVDA evaluations right now. And production ramp up in 2027/volume production H1 2028 expected. So you have a company at $1.5B MC: Critical both on the power semis front to the US government. And critical to both photonics front to the EU government. Coming off of a legacy drag cycle with auto and others (similar to Soitec). I think I’d follow EU/US government signals for what’s critical infrastructure given expected dual continent subsidies… Over random media analysts trying to cause unnecessary volatility saying it’s a memestock with no fundamentals.

Bro media… how is $XFAB a meme stock? Can you not repeat the same mistake with $RPI this time? They’re literally getting CHIPS ACT funding from the EU because of how critical they are. And have $NVDA / $NOK evaluating their SiPH side of things, while they traded at a low ~1.28 P/B. This just reminded me of $SOI low p/b but high growth verticals out of legacy segment drag. $XFAB was literally mentioned for CHIPS ACT 2 next week in the blueprints… Which focuses around photonics. The main revenue ramp was around power semis with $NVDA pushing 800 vdc. So $NVTS, $POWI, $WOLF and everyone have been taking off recently. Markets just missed $XFAB, because they’re a lesser known foundry in power semis…But US Dpt. Of commerce pointed them out as the only high volume SiC foundry in the US 2Y ago. I just happened to point out the connections. Just because you don’t understand something, don’t just go call it a “meme stock” with price detached from fundamentals.

$XFAB (photonics + power semis) is an interesting long idea at $1.28B MC, that I took positions in. Given EU CHIPS act 2 is today as the catalyst for European photonics players. > 800 VDC power semi exposure to $NVDA push through $NVTS + $POWI > Silicon Photonics / CPO exposure with $NVDA as evaluation stage for high volume manufacturing (optical transceivers/switches) > The only high-volume SiC foundry in the US. > One of the critical MEMS foundries > ~1.29 P/B, which was around what $SOI was sitting at when I went long. Depressed valuations due to legacy drag > ~6.5-8.5 fwd p/e 2028 personal est. > backstopped by Government: - EU CHIPS act, $128M Euros - US CHIPS act $50M PMT (department of commerce). With likely more coming (just signals critical importance to Western supply chains). So at a certain point with all the grants, they’re just getting the capex funded by the Governments. EU CHIPS act 2 is coming out this week, and I’m gonna go ahead and guess $XFAB might get included given they were before, and this package is specifically targeting photonics. ~$1.3B MC seems compelling to me if it can pull a Soitec reversal (low p/b, very high growth segments, auto legacy drag). As for the $NVDA silicon photonics relationships it’s under “photonixFAB”. Markets probably missed this silicon photonics relationship (like $TSEM when I went long) with Nvidia since XFab leads this… Just under a different name. For power semis, XFAB is named for SiC + $NVTS. In PCN-22181, $POWI explicitly names XFAB as its foundry.  Given its exposure to power semis and photonics as growth, low P/B, gov backstop (of course dyor, just sharing my personal thoughts) Thought it personally seemed compelling.

There’s one very compelling name someone called out. That I ended up taking positions in for power semi exposure. Heavily tied to $NVDA but not directly mentioned like $NVTS. Can anyone guess?

How did my $NVTS position double already lol? That aside, I did see a very compelling long out of the list of crowdsourced recs earlier for 800 vdc. Doing more research now! https://t.co/Su65NuYjLW

All right chat, crowdsourcing your #1 highest conviction (10x only) stock long for the Power Semi trade. Especially given $NVDA pushing shift to 800 VDC. Stuff like $NVTS or $WOLF, but high-beta, 10x potential only. Anywhere around the world. What's your pick? https://t.co/Y10KR6HLVC

$NVDA actively pushing to 800V, and today was a pretty big signal. "On April 22, 2026, NVIDIA has initiated discussions with major South Korean power equipment companies to explore designing DC infra based on an approximately 800V direct current (DC) system" Previous named Nvidia partners include: Infineon, $TXN, $STM, $NVTS, Delta, Flex, $ETN, Schneider, and $VRT. It's been known they're been pushing for this but... looks like Nvidia is really driving it. Personally very small exposure to $NVTS since they're they have a high exposure for SiC/GaN ICs for 800V DCs. I know others really liked $VICR for exposure.
