Penguin Solutions' relationship with SK Telecom now looks significantly bullish and could be a big deal, because SK Telecom plans a gigawatt-scale AI cloud in Korea on Nvidia's DSX platform. Per Nvidia, the first AI factory comes online in 2027 to serve sovereign, physical and agentic AI services, with plans to expand across Asia. x.com 

Penguin is in pole position to bring optical memory systems to customers because it was already developing a Photonic Memory Appliance with Celestial AI. Marvell is showing an HBM-and-DDR5 module that creates 33TB memory pools over optical links up to 50 meters, letting memory capacity scale independently of GPUs. x.com 

Penguin Solutions looks more like memory-cycle strength dressed up as an AI pivot story, and its price has already run ahead of that story. Its legacy AI factory business was concentrated in hyperscaler hardware, and the pivot to enterprise, neocloud and sovereign customers is a rebuild that the numbers do not show yet, with longer sales cycles and delayed bookings. The IP is good, and winning qualifications could change the view, but that needs a real shift first. x.com 

SK hynix's record earnings and five-year volume and spec agreements make its valuation look too low. Quarterly revenue reached KRW104.62T, up 32%, and operating profit hit $63B against a $785B market cap, below AMD's and less than half Tesla's. Its planned KRW100T (~$75B) shareholder return would be one of the world's largest, signaling conviction and unusual demand visibility. AI-inference 3D DRAM is coming by 2030; a reasonable valuation is all that is sought. x.com  x.com  x.com  x.com  x.com  … Show more

SK hynix has unusually strong earnings visibility because it expects memory demand to exceed supply through 2030, while long-term agreements with 14 customers cover more than half of its 2027 and 2028 production capacity. Record Q3 operating profit of KRW 83.3T also beat the KRW 76.7T estimate. x.com  x.com 

Penguin Solutions buyers chasing Marvell photonic memory are likely to be disappointed, because Penguin is a Super Micro-style integrator, not an IP holder, hence its low price-to-sales ratio. It builds the 2U chassis inside the rack around photonic memory IP from Celestial AI or Marvell, which own the high-margin foundational IP, and that work is still in development collaboration, not even qualification. The base business is a legitimate idea, with material upside if it gets past sampling. … Show more

SK hynix's exceptional margins and contracted capacity underpin a bullish outlook despite shares sitting around half their June high. Q3 operating margin reached 80%, up from 47% a year ago; long-term deals with 14 customers cover over half of 2027-28 capacity, and management expects demand to exceed supply through 2030. x.com 

Google's growing TPU business needs HBM, adding demand for Micron, SK hynix and the memory basket. Google Cloud rose 103% to $30.7B, with backlog reportedly $561B; UBS models more than double TPU shipments in 2027. Micron should be up double digits on this, not down 5%. Samsung has LTAs with 10 major customers and is negotiating with 10 more, targeting 60-70% of capacity under contract. x.com  x.com 

Sold-out HBM and cash returns make SK hynix look too cheap for a memory cycle that has not ended. Its HBM capacity is sold through 2027, 12-layer HBM4 is shipping, and next year's HBM prices are forecast to rise 121%. A completed ₩40T buyback adds shareholder returns; a special dividend funded by a Kioxia stake sale is possible. At roughly 4x earnings by one estimate, the shares could go higher if the AI memory cycle persists. x.com 

SK hynix stands to benefit from higher HBM prices as supply remains constrained. Needham expects HBM price increases next year and tight memory supply through 2030; SK hynix has finalized 2027 HBM prices and volumes with major customers. SK hynix also plans roughly KRW100 trillion in FY2026 shareholder returns, including at least KRW30 trillion in dividends and KRW60 trillion in share acquisitions and cancellations. x.com  x.com
