SanDisk’s Memory-Standard Gambit Collides With an Earnings Verdict

The numbers tell two different stories about SanDisk right now. Over the past seven trading sessions, the stock has clawed back 20.83 percent to trade at 1,160 euros. Yet that rebound still leaves the memory-chip maker 43.69 percent below its record high — a gap that underscores just how violently the market has swung between fear and optimism in recent weeks.

That whiplash has a backstory. Part of the turbulence traces to a forced liquidation outside the company itself. The hedge fund Situational Awareness LP, run by Leopold Aschenbrenner, had piled into AI-hardware names like SanDisk with four times leverage, only to absorb a 67 percent loss before Citadel stepped in to take over the portfolio. US commentator Jim Cramer likened the episode to the Archegos collapse, calling it a “clearing event” — and SanDisk was among the stocks that bounced once those positions were unwound.

A New Memory Category Takes Shape

Against that volatile backdrop, SanDisk and SK Hynix used this week’s FMS conference in Santa Clara to unveil the first official Open Compute Project specification for High Bandwidth Flash, or HBF. The new memory category is designed to sit between High Bandwidth Memory and conventional SSDs, targeting the bandwidth bottlenecks that AI inference systems are currently running into.

The technical specs are substantial. NAND stacks can reach up to 512 gigabytes per device, with transfer speeds ranging from 0.4 to 3.0 terabytes per second over a UCIe interface. Google DeepMind and chip developer Tenstorrent have already joined the ecosystem. SanDisk plans to ship initial HBF samples in the second half of 2026, with production units for AI inference systems following in early 2027. Mass production is slated for 2027. SK Hynix, for its part, showcased a 375-layer 4D-NAND chip with roughly 2.5 times the energy efficiency, with series production for eSSD applications also targeted for early 2027.

The timing matters. It positions SanDisk as a central player in the AI infrastructure cycle well before the first chip rolls off the production line.

Supply Chains Tighten Through 2027

The second driver is structural. Reports from early August indicate that NAND capacity from major manufacturers is already largely booked out for 2027. In the DRAM and HBM markets, 2027 production is effectively sold out, with customers receiving only 60 to 70 percent of their ordered volumes.

SanDisk stands to benefit directly. The company has expanded its network of long-term supply agreements to five contracts, providing a level of revenue visibility that previous cycles lacked. That suggests the recent share-price decline had more to do with macro nervousness than any genuine softening in memory-chip demand.

Should investors sell immediately? Or is it worth buying SANDISK?

The Earnings Test

The immediate hurdle arrives Wednesday, when SanDisk reports its fourth-quarter fiscal 2026 results after the US market close. Management has guided for revenue between $7.75 billion and $8.25 billion, with adjusted earnings per share of $30 to $33.

The options market is pricing in a post-earnings move of roughly 25 percent in either direction — an exceptionally wide range that reflects how uncertain investors remain. The previous quarter offered a high bar: revenue surged 251 percent year over year, and earnings per share came in at $23.41, well ahead of the $14.17 analysts had expected. The data-center business, which grew 645 percent year over year in the prior quarter, will be the segment to watch. That division needs to deliver for the current valuation to hold up.

Industry-wide tailwinds are also in play. NAND prices in South Korea rose 35 percent month over month in July, and demand for enterprise SSDs for AI data centers continues to build. On the risk side, analysts point to expanding manufacturing capacity from Chinese NAND and DRAM producers, as well as pricing pressure from competitors like YMTC.

Divergent Views on Fair Value

Analyst targets span a wide range. The consensus rating sits at Moderate Buy, with an average price target of 1,925.29 euros — roughly 66 percent above current levels. On a dollar basis, the consensus target is $1,811.38, though some bullish voices see the stock above $3,000 if the AI memory boom persists.

The technical picture remains mixed. The stock closed Monday at 1,120.00 euros, up 5.66 percent on the day, after losing around 47 percent during July. The seven-day gain stands at 16.67 percent, while the 30-day balance remains deeply negative at minus 26.80 percent. The gap to the 52-week high of 2,060.00 euros from June still measures 45.63 percent. The RSI sits at 42.8, signaling neutral-to-slightly-bearish momentum, and annualized 30-day volatility of nearly 165 percent underscores just how turbulent trading has been.

The fundamental case for a continued recovery rests on three pillars: a new technology standard with heavyweight backing, a supply chain effectively sold out through 2027, and a data-center business growing at triple-digit rates. Whether that foundation proves sturdy enough to close the gap to the record high will depend on Wednesday’s numbers — and on the outlook management provides for the year ahead.
