$XFAB

Hmm, I personally added $AMKR in the $40's since I thought it was surprising it dropped that much after ER, even after $NVDA $1.5B deal + $TSM 10Y agreement. It's more of a 2028 name though, though they have separate ramps in 2027. - Did some cost averaging on names like Foci on drop to 400 (leading FAU supplier to $TSM COUPE + $NVDA, COUPE shows signs of ramp now from other ERs like $FORM). Added some $XFAB too after earnings since they verified CPO + 800V exposure, might be a bit of waiting though. Added $LPK on the 13 EU doomdrop, GCS isn't going anywhere, think volume ramp just got delayed a quarter because of Absolics delay and I'm fine waiting 3 months. CoPoS, Samsung, and others should drive demand more in 2027. And added OE Solutions on drop to ~14,000 KRW, thought it was strange Korea's leading EML company with independent InP fabs was only worth ~$110M MC. - Names like Win Semi + others are really really compelling to me but just dont have enough capital to add sadly without going on heavy margin. Probably want to scale into $SIVE and $AAOI more since those are my two favorites. And looking at $CCXI opportunities given Unitree IPO is around 3 weeks, that listing should boost humanoid/robotics sector a bit similar to the $SPCX halo effect. TLDR: Just moving capital around, my own personal risk management. Same names as before.

Yeah my thought was $XFAB could be an early $TSEM with actual SiC/MEMs foundry kinda bridging the gap while they develop their photonics arm. They did reiterate exposure to CPO and 2028 timeline isn't priced into any revenue models yet (which I liked about them). Might be a tad early, but we're getting closer in H2 2026 and the ER statements were very helpful.

For $XFAB ER transcript: Just to recap, my idea on $XFAB foundry growth opportunities stemmed from SiC for 800v and photonixfab/MTP for CPO applicability. - $XFAB: "We are making progress in co-packaged optics". - "The transition to 800v... is expected to support demand for both SiC and GaN... for XFAB" So those analysts/people that were confidently bearposting about $XFAB that they had "0 exposure to 800V, photonics, CPO" just turned out plainly wrong. At the time I shared my idea, industry materials showed ASE and others cited photonixfab + XFAB as an upcoming CPO player in EU. And filings showed they had exposure names like $NVTS / $POWI in general. So glad $XFAB went out to explicitly clear things up to state they were developing in CPO/800v. Okay back to the ER: - "We continue to expect photonics volume production to start in 2028". Company currently has three silicon photonics projects in development with key partners. I thought it would ramp sometime in H2 2027, but was probably early by a few months. - Several new data center design wins, eg. 3 new SiC design wins (consistent with general 2027 ramp as 800v deployment takes off). So once those ramp in 2027-2028, (markets tend to price things ahead of time), I'd expect $XFAB to be rerated based on growth opportunities. TLDR: - Current revenue numbers not as impressive. - $XFAB confirmed direct exposure to CPO and 800V shifts (biggest win for thesis) - 800V exposure opportunities for SiC (should be 2027) - Timeline is 2028 ramp for photonics volume production Happy exposure thesis to CPO/800V was confirmed from this ER. Might be a bit of waiting for revenue ramp.

Kelper upgrades $XFAB to "Buy" citing: - Melexis demand strengthening “week-after-week, day-after-day” (their lead customer). - AI giving XFAB a structural growth leg with SiC, GaN, and photonics offsetting auto cyclicality. - Scarce Western speciality foundries like $SILEX commanding higher multiples. "X-Fab remains the cheapest specialty foundry peer on every multiple, trading at 4.8x 2027 EV/EBITDA versus a peer median of 14.5x" I treat this as good signal for the core fundamentals improving like auto players. But in terms of unpriced long term growth vectors, I'm personally looking at XFAB from a different angle in terms of photonics growth with photonixfab. Given $NVDA as a potential key driver. But it's hard for traditional firms to price these types of active developments into valuation models until there's volume contracts.

I've reached 900k followers, thank you everyone! Just some reflection, it's actually a nightmare at higher counts... Which is new to me, since I started at almost nothing earlier this year. 1. Threats of safety, which I don't enjoy. - Random new accounts sending personal threats - Mysterious foreign accounts, sending coercive messages the moment I mention a foreign ticker If I hold an opinion about a stock, I'd prefer not to have anyone show up on the street with a knife at night since it's safety risk at this point... Never felt like I'd have to take that into consideration for holding an opinion. 2. Egregious media narratives - Lot of outlets try to dismiss my ideas like $RPI or $SIVE as "meme stocks" or me as "meme trader" when I talk about supply chain chokepoints or fundamental catalysts to revenue due to AI. Without ever covering the core ideas or hyperscaler mapping I've done. I let success validate my ideas, but it's annoying when they can just pretend their claims like "___ will imminently crash as a fact" which ends up not happening. Or that "___" is just a retail meme stock without mentioning $JBL, Ayar, $GFS or others for CPO scale up or pluggables. I'm grateful to some outlets, like in Belgium for $XFAB coverage, but many others try and paint their own narrative rather than covering a very nuanced thesis objectively. - When I mention a ticker in a foreign market, some try to frame me as some "adversarial account"! I'm just sharing ideas, and I'll always disclose positions/financial interest if I have them. If I say I have none, they just make up some narrative that I'm some foreign institution or random group inside their country that does. Some have even tried hilariously forging screenshots of me to harm my reputation, which was annoying to deal with. Since it's easier to textedit a photo and spread it around than it is to dispel disinformation. Lot of institutions know me personally by now. I just don't go broadcasting my identity to random people in the media/public, since personal security gets expensive and I just want to live about my day. 3. Endless X bot spam - I have endless hundreds of comments a day trying to link external communities pretending they're me. I manually delete, and block thousands of these accounts, sometimes hit regular people by accident. And it's extremely exhausting to the point my fingers cramp certain days. Even if I give the most blatant warnings in bio, people still get scammed and think it's me. Then I get blamed for it too. I actually had a conversation where someone asked if a scammer was me. I said no verbatim, then they double checked like 2-3 more times because they didn't believe I said no because someone had the same username on another scam platform. In another world, maybe we'll get automod type tools. But until then, it's mentally exhausting dealing with all of this. But I do so anyways since I don't want my followers to get scammed. 4. Endless engagement baiting - I have tons of people making up fake stuff about me, tagging me in posts, randomly bashing my ideas while missing any technical nuance in order to get me to comment or farm views. It's a catch 22 since the moment I reply, they get a lot of views, which was their goal. And if I don't reply it just looks like I'm avoiding something (which is not true). I'm very transparent, I always try and entertain people who disagree first. But when it gets into personal attacks or leading questions/disinformation rather than substance then I don't engage. It's a little sad though when people I've interacted with end up caring more about engagement over relationships down the road. 5. People missing the nuance - I share ideas pretty often and I always maintain I don't want people to copytrade or blindly follow, which is why I haven't set up any copytrading apps. Before it was just posting with a few $RDDT friends on ideas like $AXTI, $NBIS, or $ALAB, and people were more knowledgeable traders. Then seeing if markets validate my guesses like with InP substrate bottlenecks. But because many turned out directionally right, to the point it became a central talking point between China/US trade relations, lot of random folks started to follow my account last few months. But many of them miss nuances with float dilution, or material updates along the way such as rate hikes, and I get blamed if a thesis changes. Now since there's so many random people, even if I share an idea about $CBRS last Friday. At market open I had people panicking over a 2% drop, asking me if I did something to a $44B+ company, even if it went up 20%+ today. Now I have compliance review for posts, which delays things a lot but makes sure people don't get the wrong idea. And I have to be careful about my timing, so I post new ideas when markets close. Before, it was just sharing ideas the moment I had them during lunch or in the shower, so this is becoming a headache. 6. I post my core ideas for free. And I've always said this from the start. I actually made my subscribers chat literally by accident, and set the bare minimum amount on purpose since I didn't want to take people's money. But kept it so I could avoid the bots and not spam the main timeline with random thoughts/scrapped research. I think me becoming the #1 most subscribed to person on X was literally by accident. But lot of weird narratives out there when media or others don't believe that I just genuinely want to share my ideas for free. And that people shouldn't need to pay $300 in a paywalled community to see them. _ Not sure if people want to read it all, but just some things I've gone through. It's not as much fun at higher numbers and it would be nice to go back to when I was smaller. Regardless, I'd rather not turn this into a job, or make it feel like one. Will probably take a break when I hit 1M as a milestone and do something else that will help out the community like sharing my research pipelines and such. Think a lot of my friends at 10-50K follower counts, seem to experience some of these issues too. But problems get magnified a lot at this level. I never needed the X creator fees or anything, just wanted to share ideas for fun if people wanted to listen. And didn't expect any popularity, but it's nice to see that people find my ideas compelling.

Today, $XFAB (1.23B MC) receives €127.4 million from CHIPS ACT for their MEMS Foundry. "The «Fab4Micro» in Erfurt is a key project for the technological sovereignty of Germany and Europe, explained Thuringia’s head of government." The production start is planned in 2028 (finanzen). With Europe's new CHIPS ACT 2 as a concurrent fundamental tailwind.

$XFAB upgraded to outperform with a PT of €12.8 by Bernstein, up from €5. Okay I forgive you Bernstein for Kioxia and Intel. I still think that’s just reactive PTs off automotive recovery, SiC/power semi ramp up. And undershooting potential a lot… If markets price in the possibility of xfab moving to HVM. On their silicon photonics foundry w/ photonixfab / Nvidia + LIGENTEC for TFLN on SOI. Regardless I’m bullish too on XFAB and curious where it heads.

So short term ramp, I see $LPK probably might be more parabolic. Since when equipment suppliers switch from qualification to volume production as seen with $AEHR or $AIXA recently, they tend to get re-rated to $3-7B MCs. But 99% are structurally more capped on where they head. Long term, I personally see $XFAB has much much higher upside if they're able able to lead European's photonic supply chains and build out a $TSEM alternative with MTP. But are earlier on in the process.

@carlosfagar $XFAB hasn't even been a month... I made this post saying I'd prefer if long ideas were validated on medium term timeframes, not in 3 weeks lol. $SOI is up over 175% since I shared my idea?

@commieserenity $XFAB is more of a 2027/2028 play, but should recover independently h2 imo without silicon photonics, as they should come out of the automotive slump.

Don’t think there’s any new news from $XFAB. Their company needs to do a better job with marketing materials though. Since nobody thinks they’re optical ai dc or power semi adjacent exposure apparently. However, I would have thought that since they’re leading Europe’s silicon photonics value chain efforts with PhotonixFab. And apparently everyone + EU are discussing sovereign AI supply chains after Fable’s export controls. One might think they’re a major beneficiary alongside IMEC, ligentec and others in the sovereign AI push? Anyway, markets can always disagree or maybe they didn’t link things together. Regardless, I’m just curious how this plays out. (Disclosure, own positions)

Just as a recap, these were all my core European longs: 1. $SIVE 2. $LPK 3. $SOI 4. $RPI 5. $IQE 6. $ALRIB 7. $XFAB Sivers: As you know by now, core laser chokepoint over next generation photonics, from 1.6T pluggables to CPO. Embedded in many hyperscaler suppliers from Jabil to Ayar. Should go brrr 2027 but markets are forward looking, so ramps + qualifications should get priced in now. LPK Laser - Glass core substrate "monopoly" with LIDE. "More than 80% of major global players have selected our equipment for process validation, learning and scaling to mass production" Soitec - Silicon photonics SoI substrate pure monopoly while coming out of legacy drag segments. Raspberry Pi - Was my fun idea around Raspberry Pis being used for AI hardware deployments. Previously this thing was mainly educational or hobby boards, but now used for edge/local AI. Just thought revenue increase would be extremely material and it played out well. IQE - Critical epiwafer player for your Western photonics like Macom, Tower, Lumentum, and others. Was kinda going under, but thought their latent capacity relative to Landmark was undervalued. Also given how important it was, I thought that your downstream players + Govs wouldn't let it go under, so it was more of a moonshot idea earlier in the year. Lot more derisked now, very important. Riber - Kinda monopoly in the MBE space, exposure to Quantum / quantum dot + silicon photonics. Found out from OSINT help from a friend latentvalue that Microsoft Quantum was buying their machines, so this was direct hyperscaler validation + kinda de-risked at current MCs. XFab - SiC foundry backed by EU/US CHIPS Act with power semi upside. (152% Y/Y growth for their sic vertical). Main growth was their silicon photonics foundry past 2027 that's getting evaled by nvidia. And that they're leading Europe's value chain efforts in photonics, kinda like an early tower semi. We'll see how this plays out, thought power semi exposure + low P/B would derisk the company until they scale their photbunchonics efforts. From my own personal thoughts: Out of the maybe $SOI has already been re-rated the most? But I'm holding anyway. $LPK and $ALRIB I think are still undervalued despite their monopolies. $RPI is just kinda seeing how things go at this point, would be hilarious if they ended up like a mini nvidia for low end edge ai. $IQE probably has a long way to go given new tower long term agreement, alongside macom. And if they convert latent capacity, I still think it has a chance of rerating like landmark. $XFAB idk if im missing something or are markets missing something. you have nvidia as a direct eval of their silicon photonics foundry, and it's trading below replacement P/B. i think im right though. $SIVE I see has the highest upside out of all of them given laser company ability to vertically integrate, acquire companies downstream to make their lasers more valuable, etc. Just like coherent/lumentum. There's like 1-2 more random ones that aren't really material, but just in general. These are the ones I've liked the most.

@JSCC2020Lee Yep, $NVTS, $POWI, $ON, $WOLF, $AOSL $XFAB, and others with power semi exposure probably get a bump from q3 pull forward. (disclosure have exposure to xfab + navitas)

@RyanU_1F42B $IQE, $XFAB, and others are just not really well known but they're both critical to western supply chains. Probably a long way to go imo

Markets should be cheering on domestic champions like $AAOI. Since it's ideal to support critical AI infra from laser fab to production in the US, rather than being a bear. Feels like everyone just outsources transceivers to Asia like Malaysia or Thailand... With $INTC, $IQE, $XFAB, $MU, $WOLF, $SOI, $SIVE, and others... If you haven't noticed by now, they're all critical to US supply chains. And every one of them are getting subsidies for securing Western supply chains. Before a major trade was to short developing US/Western equities, then hedge with subsidized foreign ones. As seen with the energy/solar firms that went bankrupt, this backfired a lot on US AI infrastructure years later with the power grid. I wanted to help change this mindset, since I believe it's very positive sum to invest in building up critical Western supply chains like photonics today. Especially if $AAOI hits their $471m/month projections after reshoring their production to America. Instead of hoping they fail and calling critical nodes in the supply chains memestocks/bubbles, maybe it's good to change mindsets a bit so we don't see a repeat of the US Solar sector years later. US/EU don't just hand out subsidies or CHIPS act grants to anyone.

Why do I keep getting these questions!!! $XFAB is building a Silicon Photonics foundry alternative to $TSEM and $GFS. And has Europe backing it + $NVDA evaluations. It takes time... Like October 2026, should finish up development. Then 2027 production scaled into 2028 (mass production), since they've been working on it since 2023. Everyone thinks it’s a depressed automaker supplier right now. And thankfully with European names they tend to look at TTM revenue over forward growth. So somehow it’s leading EU’s efforts to create a $TSEM silicon photonics foundry + supply chain at ~€1.1B MC? That R&D directors from ASE cite + others as future CPO routes. I’m might just really early to a lot of things, but of course most of the risk/reward comes from taking a little leap of faith in seeing it commercialized. Otherwise people can take the de-risked route with Tower directly (which I also wrote a thesis on awhile back and also like).

@aphexinvests I’d expect $SOI, $XFAB, $IQE and others in the European supply chain to play follow the leader and recover as well. Everything got sold off with photonics / power semis recently.

@jim29223471 Can’t give advice on what you should do. But personally I think $XFAB valuations are a joke at $1.45B MC if they’re leading Europe’s silicon photonics supply chain efforts.

@SebastianS79509 $XFAB is European... I really like it, just markets are sleeping on it.

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.

I think my personal style of investing is a bit different, just some reflection: It's inherently discretionary, based on stuff markets don't know yet. And a culmination of life experiences? If you look at $AXTI, $RPI, $SIVE, $IQE and others. Lot of it is guessing on unstructured relationships then seeing if it's right or not down the line. $RPI is the perfect example: 1. Nobody really thought of Raspberry Pis for AI growth. Mainly people bought one or two just for class + education + hobbyist. 2. After OpenClaw, just noticed all my friends and people just buying Apple Mac Minis / RPIs for AI applications. 3. Found validation of that trend online with lot of people sharing video tutorials on AI orchestration with RPI. 4. AI was their ideal perfect growth vector, did some modeling, and thought it was compelling. Earnings comes out and I was right. Everyone in media was calling it a meme stock because there's nothing online that shows revenue growth from AI (was 14% forecasted revenue growth, turned out to be 58%, my projection was around 55%). So it was a mix of guessing next industry trend (AI using lightweight hardware instead of GPU clusters), real life trends, then revenue forecasting off my guess. For stuff like $AXTI: 1. Everyone called it a joke when I bought at ~$12. LLMs would hallucinate and say "hyperscalers/govs would have known about this by now and fixed this vulnerability with InP substrates" 2. Or would conflate very nuanced parts of InP substrate stack, where there's multiple different chokepoints in upstream processing. 3. So part of this was just discretionary based on what I've seen over InP substrate breakdowns, industry trends, etc. 4. Then also guessing the major supercycle was photonics (this was before everyone caught onto $LITE, and others). Or before you saw the $141B TAM projections from GS. 5. AXT owned 40% of InP supply chain, without them the supply chain just gets cripped). 6. All the "analysts" were forecasting steady InP substrate growth, few hundred million TAM, etc. or export controls. 7. Everyone kept trying to say $AXTI was overvalued based on TAM estimates. But if it's a few hundred million TAM you just think that's a joke and go into game theory over allocations. 8. Then I just had to guess, how much would this be worth if it were a NAND style bottleneck, what MC could it reach based on control, how much would hyperscalers price it as, etc. A lot of the current research outputs from Goldman Sachs, or earnings reports from the Epiwafer companies, were confirmed after I published my piece on AXT. If you did research back then, lot of the same material /framing wouldn't have come up. With stuff like $XFAB as you're seeing now, a lot of it is just pure guessing: 1. Not really any CPO materials, how much their MTP process makes in revenue, etc. Everyone online keeps saying they're not a photonics player. 2. But if you go through ASE docs or Gov websites, they all kinda cite XFAB as a major emerging player here. 3. $NVDA also evaluating them right now (maybe it's successful who knows). 4. No clear revenue around this area because their main silicon photonics process is still precommercial, but if you guess it's trying to create a EU supply chain to compete with $TSEM, once pre-commercial shifts to commercial, maybe similar but less volume contracts? 5. Then just seeing updates over the next few months to see if anything confirms this thesis guess. _ I think a lot of information discovery still can be done with LLMs I'm seeing online. But it's also really hard to make a bunch of unstructured inferences based on unrelated material or even just trends you're seeing in real life. So probably better to just do what's standard, eg. do valuation forecasting based on current numbers Stuff like $AAOI, if they're projecting $471m/M h1 2027 and you see MC at $12B, probably undervalued might be a good idea to go long for next years. Stuff like Samsung Electronics is easier, see what people are modeling for operating profits for 2027, 2028 then just seeing if it's undervalued or not at current levels. Maybe something harder is $JBL. I haven't really seen any great volume numbers around 1.6T LRO, but you can just make a guess on how popular that might be then project how that might impact current MCs. Or picking just good names everyone kinda agrees like $TSM, $INTC, $MRVL is also solid. So a lot of things is just building up your life skills then applying that to markets. I don't think it's that can be taught with courses and stuff. Of course, much of what I'm doing is just high conviction inference based on unconnected parts. Could always be wrong.

Uhh, $XFAB de-risked foundry. Compelling upside from CPO if they make things work in H2 2027/2028? I call this frontrunning institutions... since it's a massive guessing game few months ahead of normal repricing. Cause it's a lot of customer/document mapping + timeline guessing without formal volume contracts in place. But I think I'm right? We'll see.

Okay... just some more weekend shower thoughts about $XFAB. I still feel like it could be the next $TSEM, just early stage at a $1.4B MC? They kinda leapfrogged current gens (which $TSEM are getting volume from) to compete for H2 2027 CPO scale up inflection point ($ASX docs cite Xfab (aka. photonixFAB) as focusing on CPO) By building out some black magic MTP (transfer printing) architecture for lasers w/ other stuff like TFLN. Basically next-gen integration IP, they're still behind on yields, sure. But $NVDA evaluating it for transceivers/switches to see if it can volume ramp. That $NOK sets the specifications/assembly for. (nvidia invested in nokia for this these switches/networking too btw). And if their MTP supply chain works... (eg. with Smartphotonics providing lasers, EU players doing assembly). It basically volume ramps with $NVDA just like why Nvidia signed long term agreements with $TSEM? Downside risk? Already below replacement book value, can always go lower yeah, but typically to a certain point. Maybe more CHIPS act subsidies next few months from chips act 2. If it doesn't go well there's SiC (152% Y/Y Growth, 195% Y/Y SiC wafer shipment growth)/GaN power semi upside. Europeans /LLMs will say "oh evaluations doesn't mean it's a future contract!". This is kinda different since the European Union is behind this effort and $XFAB for soverign photonic supply chains. Not your typical company + hyperscaler evaluation, since $NVDA wants to be nice to Europe's regulators. They'd prob be pissed if nvidia just stayed in US/Taiwan/China. So if they can make this MTP black magic work with mass production, feels almost for sure nvidia/nokia volume ramp on some tiny $1.4B silicon photonics foundry or at least throw them a bone with smaller contracts. In terms of timelines, maybe just a months early since it volume ramps H2 2027/H1 2028 (which happens to be in line with CPO scale up timelines)... Or just unknown because they named their project something stupid like photonixfab? Like XFAB Photonics would have been better? so institutions/screeners can connect the dots when looking at CPO silicon photonic foundry players? Automotive should also coming out of a slump medium term, sped up by self-driving (TSM Chairmain comments yesterday said ai automotive was TSM's growth vector alongside robotics). So their core business also should pick up speed too medium term. Obviously markets/europeans want a "Nvidia signs $2B+ contract, XFab volume ramping 2027!" But by then it will be a $9B+ company and you miss out on all the upside. And especially since everyone analyst/institution is blind to volume expectations for these.... Normally don't invest in companies in evaluation stages, but this just seems very de-risked by EU sovereignty + Gov backing, and you have Nvidia + Nokia there for volumes if they can make the IP work. I think markets are probably missing something here... there's almost 0 value being assigned to being CPO exposure in Europe as their long term upside.

@Jornka329996 Are you high, I posted about $XFAB this week. Their silicon photonics platform with $NVDA and $NOK scales h2 2027 / 2028. I think it’s a heavily derisked precommercial long that looks like the next $TSEM. With upside from SiC/GaN. Just needs time.

EU CHIPS Act 2.0 proposal is now released. Great news: Photonics is now confirmed to be the new structural addition to EU policy. This is thematically bullish for the EU photonics sector. Thematically: - "This new component of the Chips for Europe Initiative supports the development of photonic integrated circuits and associated technologies" - "building and strengthening advanced design, prototyping, and industrial deployment capacities for photonic integrated circuit technologies and other photonic technologies across the Union" - "extend the Union’s design capabilities, including in photonics" - "strengthen existing and develop new pilot lines and open-access semiconductor manufacturing facilities for the prototyping and production of photonic integrated circuits and associated photonic technologies - "develop and maintain design libraries and design automation tools for photonic integrated circuits, associated photonic technologies" === More specifically policy specifically focuses on -> co-packaged optics for AI data centres (CPO/interconnects focus is bullish read through for $SIVE) -> “Silicon photonics … applications in high-bandwidth data-centre interconnects…” -> Capabilities in production technologies including co-packaging and heterogeneous integration with electronic chips, manufacturing equipment, and materials platforms for photonic integrated circuits shall be strengthened ( $XFAB) -> $SOI directly mentioned in impact analysis regarding structural strengths of the EU. "The EU has a relatively strong global position in SOI wafers, with Soitec and Siltronic being notable players" -> $XFAB also directly mentioned in impact analysis, as part of creating the current funding framework. Obviously structurally positive for $XFAB since they're literally leading the European Silicon Photonics Value chain and listed in First of a Kind (FOAK) category. Initial interpretation, this is heavily positive for EU photonics leaders that go inside AI DCs as part of EU Policy. I'm expecting optical players broadly to get a tailwind from this framework. TLDR: EU photonics structurally go brrr long term. Most positive confirmation is that photonics is structurally a part of European Union policy now. We'll likely see the individual photonics names come out after this release, within 3-15 months (typically in the middle somewhere). Markets are forward looking in general.

@laadred No, its because CHIPS ACT 2 was just published now and photonics was added. "photonics and photonic integrated circuits to the reinforced Chips for Europe Initiative 2.0" $XFAB is mentioned in some reports. The documents are too long still going through everything now. https://t.co/oFTWd0SXT8

@KayEffGeee $XFAB suddenly rose 7%, I wonder if there was any mention there. I'll go through transcripts now.

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."

So $SOI and $NOK are already more established. I looked into it deeper, and the proposals were focused around 30-500M funding and revenue incentives, to bridge the pre-volume production players to HVM. $SIVE / $XFAB map to policy incentives better, but wouldn't be surprised if larger players were there.

Europe is releasing its Tech Sovereignty Package, today June 3rd. This includes, CHIPS ACT 2.0, which is expected to prioritize photonics. Both $XFAB and $SIVE are highlighted in the Industry Policy Blueprints, which guides EU legislation. This proposes sovereign backing with €30–500 million financing facilities per company and revenue demand incentivizes. To bridge early European companies to volume production. I personally expect my two thesis ideas to be large beneficiaries: - $XFAB, given they're leading Europe's SiPH value chain, with Nokia and Nvidia evaluating them for photonics HVM. - and $SIVE as Europe's leader for lasers in AI datacenters, scaling lasers to mass production in 2027. More details will be announced today, but this is a structural tailwind to photonics critical to Western and especially EU supply chains.

@StocksAREnuts Yeah I’m up like 250% on $SOI, I’m surprised markets missed the at one… Also quite surprised about $XFAB valuations given they seem to be leading Europe’s photonics supply chain development…

Tbh $XFAB lowkey reminds me of early $TSEM. Just sub <$2B MC. You basically never find a company with $NVDA and $NOK actively validating your pre-commercial silicon photonics foundry… (photonixFAB) While getting CHIPS act/Gov grants to subsidize capex. While leading the Europe’s effort to build a photonics supply chain. Feels like that alone would justify valuations… but you get the power semi SiC/GaN operations for free too and all its assets. CHIPS act 2 is coming out tomorrow, and $XFAB is listed in the photonics blueprints. Did I miss something? Or did markets miss something?

A special thank you to the only European stock green today: $IQE. Up to $54, from when I went long at $12-13, 4 months ago. Unfortunately lot of volatility with the other ones from $LPK, $SOI, $XFAB, and $ALRIB. https://t.co/FysZyHk5OK

From what I’ve seen, cyclical slump 2025. $XFAB was already dragged down, since it’s close to P/B value and lower than actual cost of asset replacement value from personal est. For Melexis, it’s also a guess we’re near the bottom of automotive cycle for legacy drag kinda like $SOI. To allow for growth verticals in power semis to silicon photonics to carry valuations.

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

$SIVE is an extremely singular case just because of major US presence already from customers, cap table, CHIPS acts, and others. Staying primarily in Sweden with a local market that tries to hinder their growth, isn’t ideal. I wouldn’t say the same redomestication is the right path for other primary EU firms like $XFAB or $IQE and would encourage local European growth there given EU supply chains.

Very grateful for the objective coverage in De Tijd! It’s cool to see my work in Belgium's top newspaper. Also very refreshing to see a journalist cover $AAOI, $XFAB, $MRVL Celestial, and the nuances behind my supply chain thesis in CPO + Photonics. Ty KLismont for the photo. https://t.co/1GdLxJHAsN

- $AAOI at $12B - $SIVE at $2B - Foci at $2.8B - Shunsin at $2B Usually the best risk/reward to me currently. Lot of my answers before like $AXTI already 10x’d, so different lineup this time. $AAOI due to absurd H1 2027 revenue projections from capacity ramp, doing everything from laser fab to assembly in America. $471M/month… that’s in 2027, the TAM increases exponentially in 2028. $SIVE is also ramping absurdly high, 77% revenue pipeline growth of the entire company’s history to ~$799M Primarily from photonics… in a single quarter. And they’re projecting 60% gross margins off that. Foci - $NVDA / $TSM primarily FAU supplier and bottleneck for COUPE. Genuinely not sure how this is $2.8B. BOM share for their passive components + FAU are massive in 2028. Just a bit early H1 2026. Shunsin - Legit you see Foxconn get CPO/photonics related orders over and over for $NVDA and others. Just nobody knows the packaging/testing gets done by Shunsin. A lot of contracts are also under Shunsin’s subsidiary too.. so markets/algorithms don’t know what’s coming imo. Runner up is $XFAB, they’ll probably be central to EU CHIPS act 2 for silicon photonics at ~$1.5B MC. And of course SiC/GaN foundries should go brr with 800vdc push by Nvidia. Especially if they’re the only high volume one in United States per Dpt. Of Commerce. And it’s such a low price/book ratio so you’re kinda getting the company upside for free, while US Gov/EU Gov subsidize their capex.

Just in case people are wondering about my track record with European equities: $RPI: $280 -> $800 (agentic AI hardware demand thesis). $LPK: ~$6, thesis at $13 -> $24.2 (glass cores substrates close monopoly) $SOI: $44 -> $181 (silicon photonics, monopoly over substrates) $SIVE: $4 -> $71 (CPO, critical chokepoints over lasers). $IQE: $12 -> $47 (latent epiwafer capacity, information discovery around downstream photonics companies). $ALRIB: $5 -> $15 (duopoly, synthesis around quantum buyers with photonics growth verticals). And now $XFAB at $9. I’m not always right. But every single one of my European longs thesis have been validated so far by either earnings, investments (eg. $MTSI in IQE) or market returns.

I mean all my European longs from $SOI, $IQE, $RPI, $SIVE, $ALRIB followed this trend if we just look at chart. Long term they’ve all ended up directionally right, and now they’re all up hundreds of percent. I don’t control or trade volatility with $XFAB, but interested in being a part of their long term growth vectors with power semis/photonics.

There was a wave of negative news when I first went long on $SOI that caused unnecessary volatility. It’s now up 300%, turned out institutions bought up the float, after my thesis. Regardless of unintended volatility, my goal is to secure critical nodes critical to the US supply chains like $XFAB.

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.

Appreciate the more neutral coverage by Reuters and Bloomberg on $XFAB today. Although it would be nicer to focus more on the structural thesis presented… Around 800 vdc power semis $NVDA exposure + with ongoing $NVDA / $NOK evaluations for photonics. And around CHIPS Act semiconductor sovereignty as the near term catalyst. Rather than around volatility from novel information synthesis. I spend a lot of time looking at regulatory filings to find compelling things market missed you know…

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.

@MalteAnkan20 $XFAB is more tethered to power semis growth. With silicon photonics upside optionality depending on how $NVDA / $NOK evaluations go

Yeah would not be surprised to see $SIVE, $SOI, and $XFAB funding with EU Chips Act 2. Glad to all my longs there (aside from $IQE) listed on the blueprint, I didn’t see that earlier in my research! Looks like formal announcement got pushed back to next week though. https://t.co/2SdG4Gocql

@DisruptivePoltx Yeah they have close relationships with $IQE, $SOI and my other longs. Was familiar with a lot of the private photonics companies working with $XFAB so liked it a bit more.

Yep, there’s a lot of interesting things going on with $XFAB in terms of European’s photonics ecosystem and existing gov funding. Basically power semi exposure, for primary revenue growth, and silicon photonics in EU ecosystem as extra. Regardless I like the idea of supporting and securing Western supply chains for AI.

$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.
