$AXTI secured LTA with $COHR earlier, with a $22.3M reservation payment. As well as a LTA with $LITE today, totaling $87M ($43.5M + $43.5M) again to reserve capacity. Considering that these are both of the two leading optical players, seems positive. The actual details such as pricing of the contracts aren't known, so we'll find out more.

I personally quite like their fundamental position right now after Mirantis acquisition, existing GW scale capacity, and leaked Anthropic memos of securing compute in places like Australia. They’re sitting right in the middle of a massive bottleneck. As a proud shareholder, main concern still is improving financing structures (not with ATMs) and removing the excessive CEO SBCs -> having them try for appreciating share prices rather than share count. Two fixes and I think other shareholders will be happy.

Global indiscriminate AI deleveraging right now, $AAOI is one of the high-beta names affected. I'd personally be surprised to say the least if they do $5.6B annualized revenue in 2027 (off of $471m/month projections), and remain a $6.3B company. $LITE annualized right now is ~$3.23B and they're a $48B company (but higher margins)

I kinda expected it for critical minerals since Western needs as much subsidies as possible to compete with China. US Gov taking a stake in $GFS for CPO was not on my calendar. But it does go to show CPO becoming a compute supply chain priority and they made Globalfoundries a domestic champion. Which my thoughts are that it's positive for all the Western players this US CPO supply chains like $LITE / $SIVE. Not so much for other parts of the world.

@4intheflames I don't own $GFS, but I'm personally it's surprised it's still down on the news US Gov is taking a direct stake in them for advancing CPO. Surprising to say the least, given everyone remembers $INTC as the latest foundry the US Gov liked.

US Gov to take 1% stake in $GFS, and award them $300m for the US CHIPS ACT. This is actually a strong read through on $SIVE / $LITE, given this CHIPS ACT is specifically aimed at advancing CPO + Silicon Photonics. (For reference, Sivers and Lumentum were the only two public laser suppliers named in GFS presentation slides. Sivers laser arrays was named recently as a reference design in Globalfoundries SCALE for CPO). Per US Gov announcement: "GlobalFoundries will receive up to $300 million to accelerate domestic CPO R&D by two to three years" (NIST) Never thought we'd see the US Gov / $INTC foundry playbook for CPO in specific...

I personally see it as extreme short term deleveraging that overshot many individual names. - $BE to $TER reported blowout results, with Bloom reporting 166% Y/Y rev growth + expanding margins + raised 2026 guidance... Teradyne reported 104% Y/Y revenue growth with 300%+ EPS growth. Your leading optical players over in China reported amazing preliminary earnings + extremely strong read through for the Western photonics sector. Think earnings season tend to remind markets about continued AI acceleration. I'm expecting $LITE, $SNDK / SK Hynix, and sector leader ERs to continue that trend. But it does feel like markets are rewarding existing acceleration more rather than future growth a year out over near-term revisions as seen with $AMKR. But as a TLDR, looks very positive for the themes I'm tracking. - Then you have $GOOGL capex raised to $195-$205B, which is typically the biggest AI demand signal from hyperscalers. - 77% 0bps change est. next FOMC decision from prediction markets. Trump administration on Monday called for the Fed to lower interest rates. So your 3x rate hikes fears this year seem kinda overblown. - Chinese fears from DUV to $CXMT overflooding are extremely overblown as well. We see this with every sector from time to time until people remember that lasers or HBM bottlenecks for a reason. As for personal thoughts, it was unhealthy seeing everything rise up or down together, especially with these themes. But I'm personally not worried since I have full conviction in my names, especially optical interconnects like $SIVE or $AAOI. $META compute and $GOOGL GCP margins/growth shows increasing demand for $NBIS and similar neocloud business models. $META + other hyperscaler notes around LTAs with $SNDK and Samsung/SK Hynix, $MU point to structural memory demand. Can go on and on... But when you have Jim Cramer telling every margined DC trader to "sell everything" at market open and news saying there's an AI bubble. I do hate it when others say "it's dropping so sell". My belief is that the important thing to look is accelerating revenue/EPS growth. And if that thesis stays in-tact with revenue acceleration in line with hyperscaler capex. TLDR: I see signs of AI demand / revenue acceleration, hyperscaler capex is one of the most important things to track. And my guess is that we'll see the theme recover broadly. But I can't predict what hour, day, or week that happens.

@wannabepanacea I've been out if it recently, just recovering from 2 rounds of surgery. Drop was been surprising to say the least given $GOOGL hiked capex guidance last week. Will need to check on rate hike odds, but my guess is just deleveraging.

Just some TLDR news: - $CXMT IPO tomorrow if you like Chinese memory. - Samsung Electronics reportedly struggling to secure large FC-BGA substrates. Ibiden (4062) reportedly requested LTA guarantees, Samsung Electro-Mechanics sought prepayments. - Samsung + $AVGO sign memory + foundry AI framework through 2030, expected to exceed $200b - $SOI expects FY2027 silicon photonics revenue to double compared to the previous year, surpassing Morgan Stanley's 60% growth projection. Photonics thesis go brrr. - SK Group + $NVDA sign $500B+ partnership to build out AI DCs and HBM4 memory. - SKC Absolics glass core delay to 2027 from reports. Targeting final reliability testing EOY, mass production next year. So if you're curious, this does push back some ramps from $LPK and others (hence drop on ER). - $QCOM price hikes by double digits for smartphone processors, due to upstream supplier hike pricing. - $META expected to issue $12B in project-level/SPV financing for El Paso, Texas AI DC expansion - Naver announced a $10 billion investment from $NVDA and Brookfield to construct a 1GW-scale AI Factory. Near term plan is 200MW by 2028. (Nvidia $1B investment, Brookfield nonbinding $9B) - 64GB DDR5 server modules rises 146% versus end-June contract pricing - $INTC brought forward 14A process mass production by a year, risk production H2 2027 and volume production in 2028, vs. 2029 HVM expectations. - Samsung Electro-Mechanics wins $200m MLCC order (existing bottleneck). - $AMD (the Bandana bottleneck), announces Helios is in full production with shipments Q3 2026. Including an up to 2GW MI455X GPU deployment with Anthropic and a 6GW infrastructure rollout with OpenAI. Gave new >50% CAGR TAM to $220B by 2030 from $26b in 2025 for CPU market. Rolls out optical interconnects for Mi500 in 2027. From channel checks, AMD is heading down to the CPO route (seems likely to use Ayar). - $ORCL wins $7B Department of War enterprise software contract - JX metal doubles semi target capacity at its KR subsidary with a 4B yen investment, with operations to begin H2 2027, amid surging demand from major customers Samsung Electronics and SK Hynix - Tungsten hexafluoride spot prices surged 2.1-2.5x Y/Y following Japan's Kanto Denka and Chuo Gas announcing permanent production halts. Fluorinated liquid supply faces a vacuum as 3M plans to exit PFAS production. - From the four optical chipmaker earnings, Yuanjie/Eoptolink/TFC Optical/Dongshan Precision: no major order cuts, 1.6T shipments expected to accelerate into 2027. Optical chip suppliers expected to capture outsized margins from shortages. - Unitree Robotics Targets 30,000 Humanoid Robot Production Capacity by 2026. Read through on humanoid TAM scaling like $CCXI and others. - Energy storage lithium batteries orders increase first half orders by 2,900% apparently in China. Not as familiar with EVE Energy and other battery makers.

Feels like every other car you see in SF is a Waymo. Short-medium term I see it as negligible impact to $UBER and $LYFT. Long term I see them cooked in US markets unless they act… Since autonomous vehicles can compress cost/margins of human ride shares by a lot. Then robotics can compress cost of delivery if Waymo launches a competitor to Uber Eats. Just like how people compare uber/lyft costs before rides, what people care about is lowest cost out of the bunch, and directionally Waymo/$TSLA would likely win there

There you have it, $GOOGL Waymo to explore split with $UBER per FT. My view last year was that Uber partnering with Waymo was a bad choice… since Uber would just serve as a distribution funnel that Google needed as they scale up. And that $NBIS Avride, other neutral players, or vertical integration would be the optimal path forward. Now their own partner Waymo looks to be the strongest disruptor to Uber.

Not exactly for $AAOI (they're working on CPO too, just a little further behind in commercialization). There's a podcast that featured the $SIVE CEO recently called: "Market Insights: Photonics & AI". Most interesting take was: "Pluggables will be around for the next 10 years". There's a lot of CPO + RNG/MRC optimization TAM cannablization arguments for pluggables recently, but looks like it's here to stay. And that there's going to be multiple architecture paths going forward (CEO also NPO alongside CPO as an major opportunity in the next 5 years). As for challenges: Vickram stated manufacturing capacity + availability of raw material is the main bottleneck. Likely referencing the existing bottlenecks with upstream CW laser ramp. From the podcast, seems like a large focus was on pluggable markets due to larger near-term TAM (which is understandable with $JBL + other players), with CPO being the north star. So it might be interesting if $SIVE M&A ambitions were to acquire more pluggable optical transceiver IP, like what $LITE did with Cloud Light. But TLDR: Lot of different paths moving forward, pluggable here to stay, CPO seems like North Star for where industry is heading. Feels like there's room for every qualified laser supplier given the industry demand is growing faster than what they can all collectively make.

Main thing was executive commentary on CPO thematically. Regarding $AMD + hyperscaler adoption + timelines. Checks were very positive for the CPO segment that sold off on delay news. And very positive for $SIVE in that segment, since they're the laser supplier for Ayar, $GFS, that are both linked with possible $AMD CPO routes. But couldn't get direct supplier confirmation since that's confidential.

From $AMD Advancing AI, channel checks: Helios networking partners told me they expect AMD to pursue CPO for future generations of Helios scale up networking. And expects other hyperscalers + industry to go down the CPO route. One AI infra executive at a company involved in a hyperscaler CPO programs said they had seen no indication of CPO scale up supply chain delays. Pushing back on recent 3rd party delay reports. This was informal commentary, not official AMD or partner guidance.
