Sure... Random train of thoughts on markets now, optics like $LITE / memory + $IREN / Anthropic. On Memory: - Demand visibility on $MU / Samsung / SK Hynix extend into 2030-2031. Samsung has LTAs covering 70% of their capacity into 2031 (likely with SK Hynix type price floors)... and their operating profit is already absurd. There's a consensus that shortage in 2027 will be much more severe than 2026... Even $SNDK expends gross margins to exceed 80% entering 2030. You're going to hear Acer and other CEOs that want memory prices to go down cite bear cases like CXMT/YMTC, and Chinese players. But just looking at supply procurement that $NVDA is doing + hyperscalers, demand visibility is absurd for the next 5 years. And by that time, cumulative FCF coming in from these take/pay + pricing floor contracts might exceed some of their entire marketcaps so it feels like there's some baseline. Near-term is always volatile (IV dropped a ton across $EWY to $DRAM to $MU), so people with call options likely got nuked, along with underlying prices. But if Samsung is 3x 2027E, has 5 year LTAs with 70% of capacity committed from hyperscalers, and price floors, it's kinda hard to see these names suffer a sustained crash... For optics: - $LITE is literally sold out into 2029, starting discussions into 2030. With demand visibility lasting into 2031… with hyperscalers largely funding the capacity buildout. Their 2028 Greensboro fab expansion was ~$5B in UHP laser capacity revenue alone, yet it’s basically allocated toward $NVDA (50%+ with options for more) and co from channel checks. Existing supply chain bottlenecks are extremely severe as optical content/XPU skyrockets entering 2027-2028. So everything from DSPs/TIAs, photodiodes, lasers, InP/SOI substrates, wafers (epi, SOI, etc) are expected to go brrr. And what does that imply to anyone else with enormous amounts of capacity coming online like $AAOI + $SIVE + $MTSI capacity expansion in 2027? Or other players like Sumitomo / Furukawa? But again it's not quite the same situation as memory since the BOM % is extremely low in a cluster... If micron/samsung raised another 2000% hyperscalers would go bankrupt. But doing that for InP substrates seems possible. Or a 100% increase on CW laser content. I actually thought $LITE was overvalued at $100B+ MC, relative to capacity expansion on your smaller optical players to their respective MCs. So I chose to position accordingly (But lumentum does deserve premiums for demand visibility). For the companies leading the charge like $NVDA / $AVGO / $MRVL: - Nvidia has 70% forward revenue growth FY2028 which is supply constrained growth. - Broadcom 100% Y/Y for 2027/2028 which is also supply constrained growth. - Marvell FY2031 upgraded guidance to $70B-$90B from $46B analyst projections... They all seem to be very happy.... and read through on demand for next 2-3 years is enormous (also echoing what $INTC CEO said today on the panel with $AVGO CEO). So you have overwhelming growth on memory + photonics + from the leaders... But the nuance is not everything in the AI supply chain get the same economic benefit. HBM/Laser/CPU/MLCC and other players in the bottlenecks look to be printing money. And seem to be the largest beneficiaries of the current bottlenecks. Test players are also getting price hikes + capacity allocated by players like $NVDA, but economic impact seems a tad lower than other players since forward P/E for many I modeled were still in the 45x+ range even if you hiked prices like 10-30%. As for capex intensive players... there's some like $IREN ($25-30B for 2027) that despite a deal with Anthropic ended up dropping. I don't think markets seem to appreciate players spending a lot of money + ongoing financing (think they're like halfway through their $6B ATM). Just some hopium for $IREN investors, $NBIS also signed a deal with $META at the start of the year (but markets didn't care at all, since Nebius dropped to ~$70-80 at the lowest point?). But did 6 months later, as the time to revenue inflection gets closer and you're past the ATM/capex window, markets would likely care more. I don't think it's irrational but at the same time, the fundamentals have improved from Mirantis acquisition to others. I also think it was known for awhile it was either OpenAI/Anthropic from CEO comments earlier too? But either way to be a more risk-off environment where funds seem to be rotating to larger names as a flight to safety. $CRWD / $PLTR as just two example, but my take is that the valuations of these rotations are reaching clown levels. And that certain AI supply chain beneficiaries in comparison are undervalued now. I was thinking markets would just rotate to names that are extremely profitable like Samsung or names that have <2X P/E, so it was surprising to see $KOSPI and some legacy memory players get sold off today. Since all of this is colliding with uncertainty about sht macro environments and renewed sustainability concern of AI capex/commitments from frontier labs like OpenAI/Anthropic from due to that FT piece recently. I've always been sounding the alarm about the contractual backlog OpenAI has with $CBRS, $MSFT, $ORCL and others earlier in the year. But OpenAI did just raise $122B or so , so I don't quite think they're at risk of going down anytime soon. I also don't think overall capex can just exponentially go up, but even if it stalls / hovers around a certain point or even drops... Capex toward certain areas like optics will still explode as hyperscalers fight over allocations when CPO scale up comes about, but might drop in others where more capacity comes online like test or DRAM. So it's a lot more nuanced than capex down = everything down or vice versa. I also slightly agree with community agreements that open weight models wouldn't lessen demand on AI infrastructure (otherwise $NVDA wouldn't be funneling funds into Reflection), but all the contractual obligations that Anthropic has might get messy if their models/company get cannibalized. Either way, I'd expect some of these frontier lab valuations to likely compress but I do think Jensen knows what he's doing though to avoid contagion. But basically: - Extremely difficult market now, can't just throw money at any AI supply chain company like $GLW and expect it to go up. There's cause for concern of rate hikes mixed with financing per $AVGO CEO but not to the point you just blindly sell off everything. Also I think markets are stupid and ties baskets together so that leads to mispricing + individual buying opportunities with certain chokepoints too. If capacity + demand is visible and forward p/e compresses like $AAOI to single digits off hundreds or thousands of percent growth from hyperscalers off $471m transceiver revenues and hundreds of thousands of monthly ELSFP capacity. Or $SIVE coming online with 100M+ laser capacity + multiple foundries with ASP hikes on lasers. I wouldn't lump them into other AI supply chain names in IP like $RMBS or others. My take is that AI supply chain beneficiaries with closer inflection points, demand visibility, and forward P/E compressing due to economic leverage would likely outperform medium term despite current volatility. TLDR: - Memory strongest risk/adjusted return with LTAs + pricing floors extending to 2030's + buybacks. - My opinion is that optical supercycle for 2027-2028 with CPO/NPO is going to look absurd relative to capacity coming online of smaller suppliers. - Overwhelming fundamentals/growth colliding with sht macro + media scares - Markets are stupid and groups things in baskets and sells them all off together or buys overvalued names, creating short/long opportunities I'd give a prayer to people on short term options given underlying drop + IV decline, but there could be a reversal... who knows. Most valuable thing right now is time.

Citibank TMT: "lasers and optical fibers are being positioned as the "next HBM." I've been talking about lasers like $LITE / $AAOI since 2025... and architectural shifts toward CW, ahead of the current industry consensus. And fully agree with Lightmatter/Citi. Just for reference: For lasers: $LITE / $SIVE / $AAOI / $COHR / $MTSI / Furukawa / Sumitomo are your better known ones. For fiber: $GLW / Furukawa / Fujikura / Sumitomo are your more well-known exposure (obviously a lot more in the supply chain) *disclosure, personal exposure to theme With added commentary that: "Tight supply conditions will support a scarcity premium for these assets." We're already seeing price hikes with lasers as seen with $SIVE channel checks at CIOE 2026 Shenzhen today + $LITE commentary from earnings. So I think the 2027–2028 photonics supercycle will look a lot like memory did in 2025–2026. Especially as optical content/GPU-ASIC goes up significantly per Goldman Sachs revised estimates...

Glad $SIVE is attending CIOE Shenzen and hope my followers can go too! If you want my read on current landscape: -> Chinese pluggable makers like CIG (剑桥科技) are facing severe shortages in 70mW-200mW lasers. If you look at filings from CIG, they claim "substantially longer delivery times and deposits to secure capacity” along with statements of shortages. -> Innolight and others were also looking to secure multiple laser suppliers with LTAs recently from their filings. On the US side of things: -> $COHR was a major merchant laser supplier before, but largely withdrew from the market after rerouting them internally. "I do not see any time in the near future where we would be selling Indium Phosphide lasers externally." From their ER transcript. And then likely turned into a buyer in an already supply constrained market... where "over the long term, we will have some portion of our datacom transceivers that will be supported by external sources." -> $AAOI not really known to be a merchant supplier, but said same thing about laser capacity being rerouted towards transceivers. And having to turn away customers for lasers. -> For $LITE, they still supply lasers but stated: "We are commanding a significant price premium" for CW lasers $LITE Wupen Yuen: "wherever they can get the laser source, they will use that solution to support their build-out." So hinting... about customers just finding anything available due to shortages. -> $MTSI has no meaningful capacity online now, but they're already stating customers are approaching them with urgency to secure CW laser supply. -> Trendforce reported $AMD and hyperscaler CSPs are aggressively going out to secure CW laser supply to avoid future bottlenecks. And then you have Europe... Where $SIVE is coming online with "tremendous capacity available now" from their foundry partners. With 100M+ laser capacity Q4 2027, and maybe if you look at their 2:1 ratio implying ~200M targeted laser capacity from external foundries. They also happen to offer the same power range (70mW, 100 mW, 200mW) as the ones currently in shortage by pluggable makers in China. There's a massive void to fill, so this dramatically increases the chance of converting customers. (esp. Supported by Lumentum statements) My speculation was that some of the 6 active pluggable engagements were from China? Which is why they're attending the conference. So to any of my Chinese followers, maybe you can ask a few questions like: - if Europe is a laser source geography, if Innolight/Eoptolink/Cambridge are considering $SIVE. - if they're seeing ASP hikes in lasers, and what CW products are hardest to obtain If you are attending CIOE in Shenzhen!

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.

Lot of people were wondering about $SIVE earnings in 2 days. What I'm watching out for: 1. I'm hoping for more visibility on photonics co-development/qualifications/contracts. -> $AAOI stated multiple customers approaching them for CPO lasers (but had to turn them away) -> $MTSI stated many customers approaching them for CW capacity (but doesn't come online until H2 2027) So read through for a company serving as $GFS reference laser, $JBL for pluggables (ex. intel siph), to Ayar for CPO. And in a merchant position: -> with independent CW DFB supply (with Win semi) -> CPO-grade lasers. Is incredibly positive for more customers approaching Sivers. 2. Ongoing developments turning into volume -> I'm most excited about $JBL, which would probably be the main revenue ramp in H1 2027. -> $AEVA is likely much smaller in comparison, but should be a contributor H2 2026. -> Ayar and optical I/O players already stated 2028 for HVM, so not really expecting much there. -> Co-developments from their other pluggable players (from last ER) turning into qualifications -> volume). Aside from that: 3. NASDAQ listing -> We already got timelines for that "next few quarters", so it's not really a focus to narrow that down further. Always nice to get an update. 4. Financials -> Again, current financials aren't a focus for qualification-cycle players. Just a heads up, there's some one-time accounting this quarter, which affects things optically. Main thing is volume ramps for future quarters. -> revenue pipeline increase -> any early volume contracts signed Balance sheet concerns should be cleared now given their recent $70m fundraising + bootstrap dilution overhang gone. Bonus cookies: -> Any information about allocations secured "eg. we have substantial CW capacity secured -> would be extremely high signal given current shortages. -> Reiterate demand that AOI, Macom, Lumentum, Coherent stated. "eg. any capacity we get would be filled from demand" $AAOI had their massive $30 -> $220 rally after they stated like $471M expected capacity in 2027, and reiterated that into revenue guidance. (but then had a lot of ATMs) An ambitious bull case + full capacity revenue statement for future timelines like H1 2028 for Sivers would be nice, but not expected. A further re-rating would help for M&A with a Cloud Light type acquisition for revenue acceleration in future earnings. Obviously Sivers has other volume ramps, but I think photonics is what the market is primarily underwriting. Regardless, excited for what's up and coming.

Very positive. My opinion is that the optical sector underperformance recently from $AAOI to $SIVE has been absurd. The demand visibility... is just way too stupidly high. AOI: “Even combined AOI, Coherent program altogether, is still very tough to meet the customer demand in the next 3 years” (2029) Elazr GM: "entire optical supply chain was facing major shortages." "The shortage will continue to the next few years" Sivers CEO said the same thing about InP laser demand imbalances expected for the next 3-5 years. Can go on and on about $LITE, $MTSI and other comments. We haven't even hit the inflection point with 1.6T, NPO, CPO scale out/up, and optics with memory (as seen with SK Hynix). Yet the industry is already bottlenecked by EML/CW and all your other upstream components from PDs/TIA/DSPs, transceivers, and soon FAU + others when CPO scales… I'm personally extremely comfortable watching this all play out, but just a little confused that markets don't know how to math a year or two ahead.

We got $LITE, $MTSI, $AAOI all pointing to extreme demand imbalances with lasers/TIA/DSP/etc from earnings... And now Elazr GM at their investor conference stated: Optical supply is still far behind the market demand, the expected AI optical supply chain are likely to continue for years. - "the entire supply chain is out of stock" - "the supply is still far behind the market demand" - "the shortage will continue to the next few years" "Whether it is PCB, carrier board, laser chip, or even related packaging capacity, as long as the AI supply chain link, almost all are in short supply." When demand visibility extends for years with the supply chain bottlenecked: It's getting difficult not to see photonics echoing the memory supercycle entering 2027.

Feels like my $IQE thesis Feb this year got validated alongside $AXTI and others. (I still long on both) So I stopped covering them as much. But TLDR on updates: Early this year, IQE was a distressed but critical chokepoint in the optical supply chain with links to $LITE and others when I published my thesis on it. Since then: - $MTSI signed long term epiwafer supply agreements, took a stake in the company, now IQE is bank debt free (Macom has convertibles, but that's positive) - $TSEM signed agreements for InP epiwafers. - Management explicitly said its IQE agreement was signed to secure the "strategic III-V epiwafer supply required for that roadmap" - IQE signed another ~$14M mysterious AI DC contract. The only part that's still playing out with my earlier thesis is IQE converting their latent/underutilized capacity toward AI DC segment, to match peers like Landmark in the space (which takes time, like slightly over a year if I remember correctly). There's some national security implications that I'll avoid talking about that makes them more important. But basically: FY2025 revenue: £97.3m FY2026 guidance: over £126.5m They're rapidly growing again in the optical sector, out of bank debt/distressed liquidation state, and remains a critical chokepoint in Western optical supply chains. Now... with new agreements with your leading photonics companies for revenue growth, and players like Macom serving as a soft backstop. After a thesis gets validated, typically I just sit back and enjoy growth of a business.

My main takeaway was that your merchant CW laser suppliers seem to be EXTREMELY IMPORTANT now. But TLDR of $COHR earnings: "given the demand that we see in our DC business with transceivers, I don’t see any time in the near future where we would be selling indium phosphide lasers externally" - Ton more value placed on companies that sell InP lasers externally if $AAOI can't doesn't enough capacity for first gen-CPO deployments, $COHR not selling externally... I guess that's why $MTSI said a ton of customers are approaching them with urgency for InP CW DFB lasers (and they dont even have meaningful capacity coming online until EOY 2027) $AAOI -> Internal $COHR -> Internal Buyers -> fewer places to look for capacity. "Our backlog now extends out, fiscal 2027 is basically completely booked out. We are booked really through the end of calendar 2027" [ Massive massive demand visibility] - Coherent also mentioned LTAs spanning end of decade. So this kinda reinforces what $POET CEO said at their AGM that the "big 3" are fully sold out next 2 years. "we’re not constrained in the assembly and test capacity right now. We’re really just constrained by the ramp of the indium phosphide production" - Just for the bottleneck bros in terms of assembly/test not a bottleneck. "absolutely no push-out of CPO demand. In fact, it has been the opposite. We have seen demand increase and request from customers’ demand getting pulled in" "we continue to expect revenue from CPO for scale-up applications to start to flow in the second half of calendar 2027" - Big read through on other CPO players for scale up if $LITE, $COHR reaffirm revenue from CPO scale up coming h2027. - "quarterly revenue exceeding $3 billion by the end of fiscal 2027" - $COHR revenue go brrr So for regular numbers it's: - $2.046B revenue (+13.3% Q/Q, +33.8% Y/Y), main revenue ramp looks to be happening entering Q4 into 2027 - Non-GAAP gross margins: 40.2% Next quarter guide is: - Revenue: $2.2–$2.4B revenue - Non-GAAP gross margins: 39.5-41.5% Basically: $1.69B -> $1.81B -> $2.05B -> ~$2.30B -> $3.0B (end of FY 2027) ~39% -> 39.6% -> 40.2% -> ~40.5% (gross margins) For operating margins: 18.0% -> 19.5% -> 19.9% -> 20.3% -> 21.8% Little less impressed compared to $LITE margin growth in terms of profitability, but revenue scale for $COHR growing rapidly.

So this is just what I'm seeing with $SIVE and the CW DFB laser chokepoint right now. From optical earnings: 1. $LITE: unexpected demand and imbalance for UHP CW lasers. - Had ability to price up ASP for lasers. - Scale up CPO on track for H2 2027 shipments, called out any CPO scale up delay rumors as noise. Lumentum confirmed timelines (that CPO players like Sivers sold off of misleading reports from), high margins, and extreme demand for qualified CW lasers. 2. $AAOI: doesn’t have enough CW laser capacity because of too much optical transceiver demand. - Not meaningfully participating in first-gen CPO deployments, with $MTSI not looking like they're in it either but focusing on NPO. Haven't seen much with $SMTC after their HieFo acqusition. - Called lasers as the bottleneck within a 20-40% demand imbalance for transceivers. - Says customers approaching them every week asking them for supply + to move faster. AOI confirmed demand imbalances + bottlenecks for lasers. And we got an even smaller pool for first-gen CPO players. 3. Both $AAOI and $LITE claimed Chinese players were years behind for CPO lasers and far behind stated claims in qualified capacity. - $AAOI said 2-3 years+ behind with CPO lasers. - $LITE said they haven't seen anything like Chinese claims in terms of outputs (and no recourse if it's false). Reaffirms moat for CPO related lasers, and no flooding from some shortseller claims on the optical sector. 4. $MTSI said that many customers are approaching them with urgency due to the general supply shortage of indium phosphide DFB lasers. Again, puts Sivers in the that bottleneck, giving them likely more customer demand . Among $COHR ($72.54B), $LITE ($66.57B), $AVGO ($2.13T): It's very special you get one of the public 4 Western CPO leaders at a ~$1.5B MC with $SIVE. Feels like my thesis with both: - The CW bottleneck that I predicted - CW laser chokepoint (where there's only a few CPO players, at least for gen-1) Got validated from earnings, now it's just waiting for the inflection points of next optical architecture shifts.

I think it’s a good time to revisit $SIVE ~$427m/yr midpoint capacity revenue modeled projections. Given recent industry earnings: > $AAOI cited +20-40% demand imbalance for transceivers (with lasers as the bottleneck). > $MTSI saying many "Customers are coming to us with urgency due to the general supply shortage of indium phosphide DFB lasers" (in other product lines) > US proposal ban on new Chinese optical transceivers (Innolight/Eoptolink) > AOI no meaningful participation in first-gen CPO deployments due to lasers being allocated toward transceivers. The read through is that it’s possible to apply the same capacity-demand absorption modeling applying to $AAOI, but for other laser players like Sivers too. Given the widespread shortage and demand imbalance for InP CW DFB capacity.

Some more TLDR takeaways from $AAOI ER: - They also flagged DSP and TIA bottlenecks, which is a positive industry read through for names like $MXL, then $SMTC and $MTSI. - For revenue growth, they're expecting more than $500 million revenue Q4, which is absurd growth. For reference: Q2: $191.9M Q3: ~$255M-$290M Q4: $500M+ By mid-2027: ~$1.41B quarterly revenue run-rate Always impressed by the revenue ramp from some of these optical players.

Wow, there's gem after gem in $AAOI earnings for $SIVE + other laser player readthrough. 1. AAOI not meaningfully participating in CPO first-gen deployments. "We just can’t make enough of them [CPO lasers] to be involved in their current first-generation [CPO] deployments because there’s just not enough capacity. We have to prioritize our ability to make lasers for our own transceivers first" So first-gen CPO laser deployments, might even be narrowed down further for Western players like $SIVE, $LITE, $AVGO, and $COHR. And independent CPO CW laser capacity became more valuable if $AAOI had to turn away more customers... Also remember Trendforce was talking about $AMD singing CW LTAs? $COHR / $LITE have capacity signed with $NVDA ... I thought it would be $AAOI, but they might be out of the equation. $MTSI also doesn't look meaningful with early CPO participation (eg. no mention in ER aside from NPO, and removal from Ayar website). So I wonder who players like $AMD is going to go with for Helios (eg. Sivers + Ayar more likely candidate now)? Btw, this is not bearish AAOI because they have too much demand for optical transceiver business. Just more bullish on the existing few qualified CPO laser names that have capacity. 2. Demand imbalance and bottleneck for InP lasers / optical transceivers. AOI's CEO stated kinda supported that when they said: "The customer demand is 20%-40% higher" than expanded built out capacity. "We are getting this kind of demand from several big customers almost every week. Lasers are the biggest bottleneck right now for the transceiver business" 3. China being years away from having CPO DWDM specification lasers. I covered this earlier when looking at CPO competition from channel checks. But AAOI confirming that China is "easily at least two, three years or even longer from having CPO lasers is incredible tread through on defensibility Western laser positioning in the CPO laser chokepoint. TLDR: - High demand imbalance for CW lasers and optical transceivers. - $AAOI not in first-gen CPO due to capacity constraints (not exactly bearish AAOI because they have too much demand for their optical transciver business, but even better news for the few independent players with capacity coming online like $SIVE) - China years behind in CPO lasers.

$MTSI earnings transcript: "Customers are coming to us with urgency due to the general supply shortage of indium phosphide DFB lasers" Emphasis on "Urgency", CW "DFB lasers", "coming to us". CW DFB names, such as like $SIVE and $LITE should be happy to hear about this laser bottleneck getting validated.

$SPCX / Elon Musk acquires Mesh, an optical networking startup. Which is working on 1.6T OSFP (pluggable). It’s seems they own the optical engine/packaging side of things, but likely sources CW DFB lasers off merchant companies. $SIVE is one of the more startup friendly plausible merchant suppliers as seen with Ayar to $POET? Maybe $LITE and $MTSI that were have a little history too, but less so. Regardless it’s very positive a lot of startups recently like Celestial have been acquired by Marvell. For both merchant laser supplier revenue (working with startups -> having hyperscalers like SpaceX drive revenue after being designed in already). As well as valuations from M&A desirability. Goes to show how optical interconnects is the right direction if Elon Musk is directly buying these companies.

Wow, $IQE and $TSEM sign a multi year InP epiwafer deal. Remember I told you all IQE was important to Western optical supply chains back at $12? $MTSI had to go out of their way to secure their supply with IQE. Now there’s another critical deal with Tower Semi. https://t.co/4A5PAuA3PU

VPEC new price hikes on Epiwafers today. Positive bottleneck read through on companies like $IQE and Landmark (3081) in terms of pricing power/demand for epiwafers. This follows $MTSI investment into IQE to secure capacity, and shows how important some of these chokepoints are. (disclosure: have positions in IQE)

$SIVE looks like both a chokepoint and a bottleneck for CPO next year. Keep seeing information published from nontechnical people who miss any nuances. Here’s the reason why: 1. CW lasers are bottlenecked signaled by $LITE earnings. Laser fabs are heavily allocated to EML likely from former $NVDA contracts. -> Sumitomo/Furukawa = bottleneck -> Win Semi = bottleneck $SIVE does fab-lite, so are they a bottleneck? Yes, $SIVE sits in the laser bottleneck since control output supply of CW lasers from Win Semi and other fabs from allocation way early on (CEO stated they working with more capacity from other players as well). Perfect example is Kioxia/Sandisk. $SNDK controls NAND output, so they’re a bottleneck because they control final pricing. Demand exceeding supply from Ayar, Jabil, other pluggable vendors + Nvidia NVLink CPO ecosystem… final laser supply owned by $SIVE makes Sivers a bottleneck. $SIVE is also likely primary/sole source for Jabil, Gen-1 Ayar, $MRVL Celestial, and other hyperscaler asic/merchant CPO routes. So no way to get around it (can’t hot-swap single channel cw lasers with Sivers) 2. $SIVE is a chokepoint over CPO. $NVDA use $COHR, $LITE (which likely sources external cw capacity from Japanese competitors) $AVGO is likely vertically integrated as well. However: the entire ecosystem around it from ASIC programs (Marvell, AlChip, etc) and merchant programs (Ayar, Lightmatter, Lightelligence) Are all likely designed around $SIVE. Ayar for example, likely tried to multi-source with $MTSI / $LITE back in 2022 but their lasers probably couldn’t match the level of Sivers specification with arrays (removed Lumentum / Macom from their supply chain site recently) If there’s no alternative at least for the initial generations (obviously they’re working to multi-source). That makes $SIVE a structural chokepoint to go through for lasers. Even if you look at the 1.6T LRO $JBL designed, they achieved a “drastic moat” with performance built around $SIVE likely sole source. $SIVE is also the foundry level reference laser design for $GFS, which your hyperscalers use like $AMD (likely using Sivers + maybe Ayar for gen1): If every major player, who hasn’t achieved vertical integration (Nvidia/Broadcom) is using Sivers for CPO… That makes them a chokepoint. Just look at the entire CPO $NVDA NVLink ecosystem partners: every single one are all likely using Sivers. And they all use $GFS as well (where Sivers is default reference). So $SIVE is both a chokepoint and bottleneck when CPO really scales up H2 2027, over one of the biggest architectural shifts of all time (near $0 -> $81B or $91B TAM in the next 1 1/2 years from GS research note) This is why I say $SIVE looks like it could be the next $75B $LITE over the next couple years. All of this should play out next year. And it’s still trading less than a company with $50M in purchase agreements that buys Sivers lasers to repackage them.

$SIVE is the most compelling CPO/photonics exposure to me. Addressing the disinformation: I haven’t sold and don’t plan to sell a single share. I do think this ends up the next $80B+ $LITE one day from ~$2.1B. And I personally have plans to acquire more ownership + support their M&A prospects. I believe earnings transcripts will be strongly positive. As in the part few months we’ve discovered: > AlChip/Amazon private placements, which is positive for Ayar -> $SIVE implying Trainium 4 design in > Wiwynn + Ayar CPO scale up > $JBL 1.6T optical transceiver ramp with Sivers incoming faster than markets expected (with relatively dramatic moat + demand as much as they can produce) > O-Net scaling up ELS efforts with $SIVE > $YSS acquisition of $SIVE allspace lead partner, designing Sivers into Space defense primes > New CHIPS ACT funding for $SIVE > $POET H2 volume ramp and their new $50m -> $500m order (with $SIVE as light source) > information discovery around $AAPL using $SIVE lasers for next gen consumer devices > information discovery around links to Lightelligence (went public $10B+ MC) + Lightmatter as likely customers. > Celestial volume ramp with $MRVL indicators. > new customers working on TFLN with $SIVE like Lightium > $AMD going with $GFS for CPO, and GFS listing sivers as one of two laser suppliers > Ayar removing $MTSI / $LITE from their website and signaling $SIVE as primary source/sole source > Ayar raising $500m for volume ramp (intel, Mediatek, Nvidia, amd etc) > pluggable TAM expansion signaled from 2025 annual report > Nasdaq listing expected soon > MSCI small cap index / Nasdaq omx inclusion, making Blackrock, Vanguard and others passive buyers > M&A signaled from 2025 annual report + 2 new board members that have experience in that area > $NOK as likely customer from 2025 annual report. > $LITE getting cw bottlenecked from EML contracts, $SIVE signaling capacity agreements in place with Win, making the a likely bottleneck owner + chokepoint in CPO sector. All of this market research was done before earnings. Any results is just confirmation of supply chain mapping done. I don’t think anyone cares about former quarter revenue since $SIVE is an exceptionally compelling 2027 long, especially H2 onward. Only thing I’m looking at are: > TAM expansion of the overall photonics supercycle (eg. optical engine, ELS, pluggables) either from M&A or developments > volume ramp expectations from existing companies > Nasdaq listing timelines for more liquidity to support their M&A efforts > any new customers signaled for CPO/Pluggables

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.

$SIVE is the most compelling CPO exposure stock to me. Despite the volatility. You probably won’t find something like this again until the next architectural shift in photonics years later. Out of the core laser suppliers, they’re all tens of billions? $AAOI = $15B Furukawa = $26B $MTSI = $29B Sumitomo = $59B $COHR = $73B $LITE = $74B Then there’s $SIVE as one of the core CPO laser chokepoints at $2.3B MC. Earnings are usually confirmation of all the little volume ramp hints like Jabil fireside transcripts for 1.6T LRO. And most returns are typically made before, not after official confirmation is just a rule of thumb.

When I see comments like this (and there are a lot) from retail investors: I immediately think they lack the technical depth. I'll walk through each one from $SIVE to $LPK: 1. Photonics TAM goes from $14B -> $154B In just two years time, and it's likely going to keep scaling past 2030 as it's the next generation architecture of choice. It's not going away in 1 year. It's not going away in 3 years, which is why $LITE premiums keep going higher since they're backlogged into 2028. $SIVE supplies CW lasers and is highly tethered to CPO and now pluggable transcivers for 1.6T and 3.2... For expected companies like $JBL, Ayar, Lightmatter, Lightelligence, $POET, $MRVL Celestial, and $AMD. This isn't a "trade", it's the core chokepoint and IP holder for the next generation of photonics. And it's a comfortable hold for the next few years as they scale to become the next $LITE. The risk I personally see (since they're already qualified with so many players), it's mainly how much TAM they can capture of the overall optical supercycle. (And potential risks with Win Semi volume ramp, but Win is massive so I can sleep tightly there). As just supplying lasers isn't enough to justify valuation. It's TAM expansion downward into making the entire ELS or entire pluggable transceiver that makes these laser companies so valuable. Then afterward, they can vertically integrating upward for gross margin expansion upward like $COHR into doing the laser fabs or even substrate level. And that in my view is a very asymmetric risk/reward ratio as we've already seen this done with $LITE as they went from $2B to $80B. 2. $LPK - Is the purest exposure, without the messy financials of SKC Absolics, as the next advanced packaging shift for glass substrates. Almost every single major semi company from $INTC to Samsung are adopting glass substrates. $LPK is basically $ASML of this chokepoint, since they supply to ~80% of the global players currently. Yes, there's "trade cycles" for equipment suppliers like $ASML, where if there's more foundry capex, ASML scales up. But if there's downturns, these tend to perform poorly, and don't capture all the volume ramp that happens after. However, if the MC is $650m and they're making $100-200M, revenue per costumer volume ramped, the amount they make from the glass substrate cycle will likely exceed current valuations. And they'll have baseline fundamentals (as more companies adopt the packaging shift), that keeps their valuation up. It's just a waiting game for volume ramp at this point. 3. $AAOI - This is literally $INTC but for America + Photonics. It's like saying Intel is not a long term investment. Guess where all your optical transcivers are made? China. Thailand. Malaysia. If you look at Innolight, Eoptolink, $FN, and others. AOI is building the largest Made in America supply chains for both CW laser fab, as well as 800g, 1.6T assembly. Yes, there are pluggable cycle ups and downs to this as well. There's going to be a wave for 1.6T next year, then CPO cannibalizes pluggables down the road. But since they make the entire supply chain in house, they have extreme optionality for other segments. And like $NVDA older gen-GPUs, there's going to be sovereign DC requirements for older gen pluggables from names like $AAOI. It's likely going to keep rising as it hits that $400m+/month revenue target H2 2026. There's just a lot of different short term volatility along the way like the $600m dilution. 4. $IQE - ??? It's one of the most important players in the Western word for epiwafers. $MTSI went out of their way to pay off IQE's debt because they can't have them going under. $IQE is also supplying to $LITE. The world is currently bottlenecked both on the epiwafer level from Landmark comments and InP substrate levels. Their financials were track but the raw book value, and value they hold to the entire Western supply chain... completely justifies their valuation. And other optical companies will not let their core upstream supply chain go under. As these tens of millions worth of materials would screw up tens of billions worth of downstream products. Again photonics is the next generation architecture required to scale AI. It's not Quantum where it's just "In development". It's literally here and the architecture of choice by $NVDA. I would not be surprised if all of these are a lot higher in 3-4 years time. People who think it's one and done in 3 months time "only because I mentioned it" don't know what they're talking about. Institutions would have bought up the name eventually (like Point 72 on $IQE) and retail would only find out after their valuations are 600% higher. Should really do the research before adding comments like these: These are all forward growth companies that require in-depth supply chain knowledge.

Random CPO related names I like: - $SIVE - Foci (3363) - $TSEM - Browave (3163) - PCL (4977) - $AXTI - Msscorps (6830) - $IQE - Shunsin (6451) - Furukawa Electric (5801) - $MTSI - Nextronics (8417) - $LITE - $COHR - FitTech (6706) - $GFS - $ASX - LandMark (3081) - $SOI Disclosure: I own most, not all though.

Not too shabby? $IQE is now up 4x since in the past 3 months. $MTSI paying off their debts does derisk the company long term. I’m curious if anyone listened anon? https://t.co/OFoSaFWSa9
