$MRVL SVP and CTO of Optical Engineering Radha Nagarajan, at Semicon Taiwan: 1. Names Europe/Japan for laser supply sourcing as examples for SiPH modules. Very interesting that Marvell's SVP had Europe in mind when giving examples of laser supply sourcing for SiPH modules. I can't really name any notable public EU merchant laser suppliers other than $SIVE. Japan I can namedrop a few like Sumitomo/Furukawa etc. Maybe I'm reading too much into the geography, but a lot of US players like $LITE / $COHR / $AAOI are redirecting laser capacity internally, so it's interesting that the US wasn't mentioned. 2. Silicon photonics, high-speed drivers, amplifiers and DSPs come from other suppliers, with final integration taking place in Taiwan Makes sense, with $TSM COUPE / $ASX / ShunSin, and others. 3. Nagarajan appears to say NPO could arrive first around late 2027–2028, with full CPO continuing afterward. Good to hear more about commercialization timelines. $LITE similarly sees NPO around late 2027-H1 2028, while expecting CPO laser shipments in H2 2027 ahead of CPO scale up deployments in 2028. Revenue from upstream suppliers usually hits a bit earlier. 4. $MRVL on Google's TPU program vs. $AVGO / Mediatek and others. "Hyperscalers are seeking greater supply-chain diversification. If Google selects Marvell for a particular AI-chip segment, that does not mean it will stop working with MediaTek or Broadcom". Guess he's just trying to emphasize pie keeps growing for ASIC suppliers, nothing really too new. 5. All of Marvell's advanced ICs and ASICs are manufactured at TSMC, making the foundry central to the broader architecture. $TSM backbone of AI as usual. TLDR: - Very odd Marvell's SVP highlights Europe for laser sourcing, given how small a pool for merchant suppliers there is... - NPO volume looks late 2027, CPO after that. Upstream optical suppliers should start seeing revenue earlier

$TSM Vice President of Advanced Packaging: "Foundries can scale up the optical engine, but the real bottlenecks to large scale deployment lie elsewhere... Including lasers, optical fiber, fiber-optic connectors, and test" (UDN) Just some bucket ideas: Lasers: $LITE, $SIVE, $COHR, LandMark (3081), LuxNet, Sumitomo, Furukawa Optical fiber / FAU: Foci, Browave, $GLW, Sumitomo Fiber Optic / CPO Connectors: BizLink, $GLW , Fujikura, Nextronics, COXOC CPO testing: MPI (6223), Advantest, $FORM, Msscorps, $KEYS, Chroma (disclosure: exposure to theme above, individual names not named by TSMC) There are others I like as well, such as ShunSin, which now has explicit TSMC COUPE exposure but probably belongs under a different category like packaging/integration. eg. "Foxconn unit ShunSin confirms TSMC COUPE partnership" I don't think there's anything too new vs. H1, aside from ongoing news (eg. FAU looks like there will have a demand imbalance in 2027, from a report last week). But it's helpful to reiterate overall beneficiaries from time to time...

It’s been a little disappointing to see a pattern with some people I've interacted with on X: - try to engage with the same audience, then quickly move toward aggressively monetizing it - get upset when I choose not to participate in or amplify paid groups - throw out personal or illogical attacks and try to reframe that as simply disagreeing over fundamentals When I first joined X, a lot of finance content revolved around watches/private jets + options, paywalled communities promising the "secrets of Wall Street," and squiggly-line charts. One of the things I've wanted to do differently is publish my research and reasoning openly, for everyone. I think this definitely resonated with folks given my follower growth. But of course, this growth can also create friction with people whose business models rely on using X to funnel audiences into paid services or expensive paywalls. My subscription has been $1 for months and will stay at the minimum, despite claims at the beginning I would raise it to $100. All of my core theses are published on the main timeline for free. I could put substantially more behind a paywall. I just don't want to. I just prefer sharing the ideas openly and letting everyone decide for themselves. Many ideas have worked out well: $AXTI, $NBIS, $AEHR, $MU, $INTC, $EWY, $MRVL, $LITE, $RPI, $IQE, $SOI, $TSEM, $ARM, $COHR, and a lot more. Others ran into unexpected industry delays, like $LPKF with glass substrates and Auros with hybrid bonding. Some are still playing out into 2027/2028, including $SIVE, Foci, Shunsin, $CCXI, $XFAB and the broader CPO/humanoid themes. Some are brand new like Etron/ESMT for DDR2/DDR3. And many like $JBL to Murata to $MXL, I just share for fun to see if the idea is right. Not every idea will be right. That's part of research. But I'd much rather have an X where people openly publish the thesis and reasoning so everyone can learn from it. Than one where information increasingly disappears behind $100 paywalls or becomes diluted with engagement-bait noise. Hopefully I can help create a new culture on X rather than amplify the old one.

$SIVE ER transcript just dropped, TLDR: - 6 NEW pluggable players working with Sivers now. Probably the biggest news of the entire ER next to new foundry allocations. "3 are in alpha sample evaluation stage" and another 3 in technical engagement / supply assessment stage." And now it makes more sense why their $1.2B revenue pipeline ballooned (since this was a bigger leap than Jabil). - Initial production orders with $JBL expected in the first half of 2027, with the production ramp planned second half of 2027 LFG, Jabil is a massive hyperscaler supplier and finally got clear timelines on revenue from volume ramp. - "new foundry partner who has brought on tremendous capacity that is available now" This is what I wanted to hear. Apparently they've been in the works for this for awhile since it's "available now", and THIS IS VERY MATERIAL. CW lasers are in a massive shortage and $SIVE brought on new supply outside of Win Semi (also de-risks). As you hear with other qualified CW players (anything they make gets sold), so as Sivers partners finishes their qualifications, I'm expecting the same. - "long-term capacity model where one-third of manufacturing capacity will be internal, while two-thirds will come from our foundry partners" Lukewarm on this, it makes sense they need to be vertically integrated like $AAOI / $LITE eventually but implies more capex (better after NASDAQ listing). As you see with ESMT + DDR2 bottlenecks, the operating income they get from just securing wafers during shortages and doing fabless models is incredible. And it would make more sense to fund this with cashflow down the road. - NASDAQ listing ongoing. CFO gave a very lawyer like answer, but on track as usual. - "We do not see production capacity as a bottleneck at this point in time" This is very meaningful since with their new foundry partners, implies $SIVE is coming online with a very material CW laser supply to a bottlenecked market. TLDR: - NEW substantial FOUNDRY ALLOCATION! (very, very material during CW laser shortage) - 6 new pluggable players outside of $JBL - Clear revenue ramp timelines from Jabil Heavy focus on pluggables -> NPO -> CPO seems like the progression. Only lukewarm piece was building up internal capacity but it's long term positive. Anyway, very happy after reading the transcript aside from potential capex prioritizing laser capacity (which is fine too during an industry shortage) over IP acquisition. The 6 new pluggable players + substantial wafer allocation "available now" is a pretty insane disclosure.

$SIVE earnings just got released: $1.2 billion revenue opportunity pipeline growth up 268% from December (incredible growth). Last ER: $799M (this was a surprise, likely linked to Jabil) July 2026: ~$1.2B (hinting more either more customer engagements than what's announced or larger volume ramps within programs). "Sivers continued to reallocate resources from NRE projects toward product ramp preparation. Sivers expects the impact of this transition to become visible in Q4 2026 and accelerate through 2027 as multiple programs progress toward volume production." Makes sense on timelines. Current financials reflect a qualification-stage player before volume ramp: - $5.64M in revenue (reducing NRE activity, shifting to volume ramps soon) -$3.72M in adjusted EBITDA (what to look at given one-off charges, eg. social security accounting expense) Key thing to look at is earnings call in 30 minutes, very excited so far.

I know everyone’s watching $NVDA earnings right now… But did you know Landmark signed a 4 year CW agreement with US customer to ensure “sufficient supply”? So now you have: - $LITE (capacity gone) - $COHR (capacity gone) - Landmark (capacity committed) - $AAOI (capacity for transceivers) - $MTSI (not online) - $SMTC (limited) I remember saying earlier this year CW lasers would be the next optical shift and heavily bottlenecked by Nvidia? So fun watching this play out, with players signing LTAs already to 2030 (signaling less availability for other players). Implications for $SIVE / Win Semi are very material as one of the few remaining CW merchant suppliers with capacity (+ CPO-grade lasers). Let’s see how they execute.

Since people are having fun speculating on $SKHY CPO roadmap supply chains. I'm gonna do my own guess and say SK Hynix is evaluating Celestial/Ayar. Then doing heavy evaluation into microLEDs past first-gen deployments. Both have been kinda working on it for awhile. - Ayar shown up in SK hynix's own website in the context of optical <-> memory links. - Marvell is actively working with SK Hynix in custom memory solutions (and guess who owns Celestial now). Celestial/Ayar are both also cited in SK Hynix's linked Nature Paper, which helps a bit with technical relevance: (121): Stojanovic, V. A UCIe optical I/O retimer chiplet for AI scale-up. In 2025 IEEE Hot Chips 37 Symposium (HCS) 1–22 (IEEE, 2025) - This is Ayar reference (Ayar’s teraphy optical I/O chiplet), Stojanovic is Ayar Lab's co-founder btw. (123): Winterbottom, P. Photonic interconnect for accelerated computing celestial AI photonic fabric module (cough cough Celestial) There's more breadcrumbs out there, but wanted to keep this relatively short-form. For more upstream beneficaries: -> I still think $SIVE is the cleanest read through since they're likely supplying to both Celestial/Ayar. The interposer/packaging IP layer... People were speculating $POET, but Marvell probably vertically integrated players them out this year after the announcement. Given they've had their own SiPH interposer tech/integration IP before Celestials acquisition (eg. presented a silicon-photonics interposer back in 2023) -> AMS Osram (which I don't own), seems like they're co-developing in this area given they randomly went out of their way this year to say HBM <-> optics was a TAM increase for them. TLDR: I see Ayar/Celestial as candidates for SK Hynix's CPO roadmap, then microLEDs being commercialized past gen-1 maybe 2029. (this is all speculation) Just to throw a bone to quantum dot bros, this got cited like 5 times.

Just some TLDRs of stuff I found interesting: - $SNDK 80% adjusted gross margins projections through 2030, ~75% operating margins and ~50% adjusted FCF margins from investor day. LTAs already 2/3rd of 2028 output. Minimum contracted revenue reaches $93B (MC is currently ~$239B)... Hard to be a cyclical stock when your revenue/targets are expected to continue 4Y later into 2030. - $CRWV signs contracts for 6Y old $NVDA A100 GPUs through 2029. For Neoclouds like Nebius/Iren, this is positive, since it's a counterargument for eg. Burry depreciation short thesis - conventional DRAM gross margins eg. Micron is estimated to reach an unprecedented 95% by 2027, surpassing HBM GMs per UBS read through for legacy/standard dram players like Nanya/Winbond should go brrrr if projections are correct. - Anthropic reportedly achieved 14x+ YoY growth and roughly 2.4x sequential revenue growth q2 to >$11.5B,. estimating growth to $190–200B in 2028r evenue numbers. Your frontier labs keep growing at stupidly fast paces, it would be worrisome if they didnt. - $NVDA reportedly in talks to invest $3B in SB Energy (Softbank subsidiary), creates a >$500B compute financing push with Apollo, BlackRock, Blackstone, Brookfield, Goldman, and others. $NVDA Feynman reportedly moves to TSMC A16 + SoIC + custom HBM + CPO in H2 2028 Just more nvidia news every day - $MSFT Maia 300 discussed $TSM capacity for >300k units in 2027, with expansion to 1m+. Unveils as soon as September. Likely $MRVL should be more happy from this news. For what's happening right now: - maybe GUC for Microsoft current ASIC ramp. - For the Amazon party, stuff like Alchip (I do own shares), likely is ramping now with $AMZN ASIC program H2 2026... So might be a good idea to look at hyperscaler ASIC ramp timelines + their beneficiaries. - $TSM VP of Advanced Packaging stated "the industry is likely to face not only memory shortages but also tight ABF substrate supply over the next few years"... Emphasis on few years for memory + ABF substrates for bottlenecks. Even upstream abf substrate equipment providers are happy, eg. Eternal Precision which uses vacuum lamination equipment stated orders surged, their plants have been running at full capacity, and 20%+ price hikes. - $AMAT expects advanced packaging revenue to grow >70% in 2026, versus prior >50%, and said customer discussions now extend all the way to 2030 (not too familiar with this company, but found their growth rate from 2025 Q4 $6.8B ->$7.01B -> 7.91B -> $9.12B -> $10.25B Q4 2026 projections pretty interesting) - Google said at OCP APAC said conventional 48V is running out of headroom. $NVDA detailed an 800VDC MGX-compatible rack H2 2026 (timeline, Delta / Lite-On beneficaries) - Aside from $SNDK, Nanya LTAs cover 50% of capacity. CXMT signed multi-year DRAM agreements last month, so entire memory industry seems to be following same playbook as ur big 3. - Probe cards remain a bottleneck, MPI(6223) said their probe card capacity remains fully utilized because demand exceeds supply. Already covered the CW laser bottleneck with $AAOI, $SIVE, and $LITE earlier this week, but that's another fun one. - some MLCC/component lead times have hit 36 weeks per Nichidenbo. Your Samsung Electro-Mechanics, Taiyo Yuden, Murata, players should be very happy to hear this. TLDR: AI supply chains go brrr.
