SanDisk (NASDAQ:SNDK<\/a>) and Micron Technology (NASDAQ:MU<\/a>) both just delivered the kind of quarters that memory investors dream about. <\/p>\n SanDisk posted a 251.03% revenue surge on NAND flash strength, while Micron rode HBM and DRAM to 345.72% growth. Two very different memory playbooks. One shared tailwind: AI infrastructure spending that refuses to slow down. <\/p>\n NAND Flash Roars for SanDisk. HBM Rewrites Micron’s Story. <\/p>\n SanDisk’s Datacenter segment did the heavy lifting, generating $1.47 billion at a jaw-dropping +645% year over year. Gross margin swung from 22.5% to 78.4% in a single year, which tells you pricing power has completely inverted. <\/p>\n CEO David Goeckeler framed it as “a fundamental inflection point for Sandisk”, pointing to five signed multi-year customer agreements and engagement with five hyperscalers. That is real backlog with contractual visibility. <\/p>\n Micron played a bigger board. Cloud Memory hit $13.77 billion, Core Data Center added $11.52 billion, and gross margin expanded to 84.6%. HBM4 is already shipping in high volume to the lead AI accelerator customer. <\/p>\n Sanjay Mehrotra said “memory has become a strategic asset for our customers”. The $7.83 billion quarterly capex bill is the price of holding that HBM crown. <\/p>\n July 16 is the Final Day to Tap Into the Lithium Boom (sponsor) Here’s why you should do the same before their July 16 investment deadline: lithium prices are up 75% this year, with demand projected to grow a staggering 5X by 2040. <\/p>\n With tech that can recover up to 3X more lithium than traditional methods, EnergyX is preparing to unlock up to 15M+ tons.

Breadth is Micron’s moat. Focus is SanDisk’s. <\/p>\n The Next Test Is Whether Guidance Sticks <\/p>\n SanDisk guided Q4 revenue to $7.75 billion to $8.25 billion and EPS to $30 to $33. Micron pointed to $50 billion and roughly 86% gross margin. Yet both stocks have cooled after their earnings reports. SanDisk is down 15.46% over the past month, and Micron slipped 10.62% since its June 24 filing. That looks like digestion after a strong run. <\/p>\n I will be watching whether SanDisk can convert hyperscaler engagements into visible ramp guidance beyond Q4, and whether Micron’s HBM4E schedule for calendar 2027 holds against fierce Korean competition. <\/p>\n If you want a sense of how far the memory rerating could travel, our team’s Next Nvidia Playbook lays out the framework I keep returning to. <\/p>\n Micron for Value, SanDisk for Torque <\/p>\n On the numbers, Micron screens as the cleaner risk-reward. A 6 forward PE on a company with 80.4% operating margins and HBM leadership is difficult to argue with, and the 40 combined buy and strong-buy ratings back that up. <\/p>\n SanDisk is the higher-torque play. Its 605.19% year-to-date run reflects a NAND-only story that could still deliver if High Bandwidth Flash lands, but it trades at a much richer forward multiple. <\/p>\n Micron offers durability and cash return, while SanDisk offers asymmetric upside on a single product bet. The two profiles suit different investor objectives. <\/p>\n Meet America’s Newest $1b Unicorn (Sponsor) <\/p>\n A US startup just passed a $1 billion private valuation, joining billion-dollar private companies like OpenAI and ByteDance. Unlike those other unicorns, you can invest in EnergyX right now; <\/a>but only until July 16.<\/a> <\/p>\n Over 50,000 people already have, along with global giants like General Motors and POSCO. <\/p>\n Here’s why there’s so much interest: EnergyX’s patented tech can recover up to 3X more lithium than traditional methods. That’s a big deal, as demand for lithium is expected to 5X current production levels by 2040.
