Investment Thesis
- The Thesis
- Sandisk is one of the five largest NAND flash suppliers globally, vertically integrated through a manufacturing joint venture with Kioxia, and now free to price and invest on its own since its 2025 spin-off from Western Digital. Storage is an under-discussed leg of the AI buildout — every GPU cluster needs somewhere to put the data — and that gives Sandisk a real claim on enterprise SSD demand, not just consumer flash.
- The Catalyst
- Continued NAND pricing strength as AI data-center buildouts keep demanding enterprise SSD capacity, with the post-spin-off independence letting Sandisk price and invest without Western Digital's hard-disk business pulling capital elsewhere.
- The Risk
- Memory is a brutally cyclical commodity business, and a 69x trailing P/E leaves little room for a NAND pricing downturn — this is my largest position at 7.94%, back under my 10% cap only because the position pulled back in price, not because the trim I've owed since June was ever executed. A memory-cycle turn would hurt most here, both directly and through sizing.
- The Connection
- Squarely in my semiconductor/memory theme alongside AMD, MU, and INTC — this is one of the clearest, most direct bets in the book on the AI-infrastructure buildout.
Pre-Mortem Thesis Invalidation Parameters
Codified in advance, before any of these have happened, so a future decision to hold or exit isn't rationalized in the moment. If a condition below is met, the thesis as written is invalidated and the position gets re-underwritten from scratch — not automatically sold, but automatically questioned.
| Metric / Event | Automatic Review Trigger |
|---|---|
| Position Sizing vs. IPS Cap | Trim back toward policy if the position re-approaches the 10% IPS cap on a rally — it sits at 7.94% now, but only because of a price pullback, not an executed trim, so the same cap discipline still applies the next time it's tested. |
| NAND Spot Pricing | Turns negative for 2 consecutive quarters. |

| EBITDAEarnings Before Interest, Taxes, Depreciation, and Amortization — a measure of operating profitability before financing and accounting decisions. EV/EBITDA compares a company's full value (including debt) to this figure, often used to compare companies with different capital structures. | EV/EBITDA 51.79x |
| PEG ratioPrice/Earnings-to-Growth: the P/E ratio divided by expected earnings growth. Below 1.0 is often read as cheap relative to growth; above suggests the market is pricing in a lot of future growth already. Different providers use different growth-rate assumptions, so figures vary by source. | 0.17 |

Valuation Logic
At 69.45x trailing earnings, the multiple already prices in continued NAND strength — the important question is whether utilization and unit economics support it; the bet is that AI-driven enterprise SSD demand keeps utilization and pricing elevated long enough to grow into it, rather than this being the peak of an ordinary memory cycle.
About the business
Sandisk is one of the five largest suppliers of NAND flash memory semiconductors globally. It's vertically integrated, producing most of its flash chips at manufacturing sites in Japan through a joint venture with Kioxia, then packaging chips into SSDs for consumer electronics, external storage, and cloud storage. Sandisk was part of Western Digital for nine years before being spun off as an independent company in 2025.
Why it's my largest position
Storage demand is one of the less-discussed legs of the AI buildout — every GPU cluster needs somewhere to put the data. Sandisk's spin-off gave the market a pure-play way to bet on NAND pricing and enterprise SSD demand without Western Digital's hard-disk drag. At 7.94% of the book against my 10% single-position cap, it's now back under the line — but via a price pullback, not the trim I've owed since June, so that's not a resolved discipline win. See the July letter and the Compliance Ledger for the full writeup.
Risk/Reward Profile
| Bull Case | Bear Case |
|---|---|
| NAND pricing stays firm as AI data-center buildouts keep demanding enterprise SSD capacity, memory supply stays disciplined industry-wide, and Sandisk's independence lets it price and invest without Western Digital's hard-disk business pulling capital elsewhere. | Memory is brutally cyclical, and NAND pricing can turn quickly if supply comes back online faster than demand. A 69x trailing P/E on a commodity chipmaker leaves little room for a pricing downturn — this is the position where a memory-cycle turn would hurt most, both directly and because it's my largest single line. |
Scenario Matrix
The single variable this position is most sensitive to is NAND memory pricing. This maps each case against that variable directly, rather than leaving it implicit in prose.
| Scenario | NAND pricing trajectory | Valuation implication | My estimated probability |
|---|---|---|---|
| Bull | Strengthens further as AI data-center SSD demand outpaces supply discipline industry-wide. | Multiple re-rates higher, toward an AI-storage growth multiple rather than a commodity-chip multiple. | ~25% |
| Base | Normalizes from current strength toward a more typical cyclical pace. | Stock holds near today's ~69x multiple and grows into it as earnings catch up. | ~50% |
| Bear | Craters as supply comes back online faster than demand, a typical memory-cycle turn. | Multiple compresses sharply toward the historical memory-cycle average — this is where the single-position cap breach hurts most. | ~25% |
