Task 6 · built 2026-07-27 · migrated to the Criteria framework 2026-07-29 · framework v1.5.1 Price at build $1,278.23; current price $1,095.78 (scan, 2026-07-28). Research direction: bearish. No position verdict is expressed here or anywhere else in this memo.

Every entry is dated, checkable, and carries an explicit upgrade/downgrade threshold. Hand off to equity-research:catalyst-calendar and equity-research:thesis-tracker for ongoing maintenance.


Tier 1 — hard-dated, inside 30 days

Date Event Confirmed by What to check Downgrade (→ Short candidate) Upgrade (→ Avoid / Long review)
Wed 5 Aug 2026, 1:30pm PT Q4 FY2026 + FY2026 results Company press release, 8 July 2026 Realised Q4 gross margin vs the 78.9–80.9% guide; first FY2027 commentary; reported RPO in the FY2026 10-K vs $41.6bn; bit-shipment growth y/y; Datacenter revenue FY2027 revenue commentary implying < ~$36bn, OR a Q1 FY2027 GM guide < 70%, OR RPO fails to grow despite two more NBMs signed Q4 GM > 81% with a Q1 FY2027 guide > 80%, OR RPO > $60bn
Thu 13 Aug 2026, 9:00am ET INVESTOR DAY — the single highest-value event on this calendar Company press release, 8 July 2026 The long-term financial model management deferred on the Q3 call ("we'll wrap this all up in a new model"): the long-term gross-margin target, the contracted-share-of-bits trajectory, NBM pricing mechanics, and the capital-return framework A long-term GM target < 55%, or a refusal to publish one again A contractually-supported long-term GM target > 65% with the mechanics disclosed → this invalidates the bearish research view outright

Why the Investor Day is the Catalyst Criteria catalyst. The house-vs-Street disagreement is not about FY2027 execution; it is about the durability of a 78% gross margin. The Investor Day is the event at which management must attach a number to precisely that. It is also, symmetrically, the largest right-tail risk to any negative exposure. (The prior text concluded "which is why the decision is Watchlist and not Short." No decision is emitted; the observation stands, the conclusion is deleted.)


Tier 2 — quarterly, dated by precedent

Expected Event Basis What to check Threshold
~early Nov 2026 Q1 FY2027 results Q1 FY2026 was reported 2025-11-06 The first quarter that must show whether ASPs fell. Sequential gross margin; sequential ASP direction; contracted share of bits Sequential GM decline → evidence trigger B1 fires. GM up again → the reversion thesis is a year early
~late Jan 2027 Q2 FY2027 results Q2 FY2026 reported 2026-01-29 Contracted share of FY2027 bits vs the ">one-third, can get above 50%" claim Contracted share < 40% → the NBM ramp is stalling
~late Apr 2027 Q3 FY2027 results Q3 FY2026 reported 2026-04-30 Whether the 2H-CY2027 rebalancing TrendForce forecasts is visible Any negative sequential ASP print
~mid-Aug 2027 Q4/FY2027 results FY2026 reported 2026-08-05 RPO run-off vs schedule; first NBM contract anniversaries RPO below $30bn with no new agreements

Tier 3 — industry and supply-chain data, no earnings call required

These resolve between prints and are the cheapest way to be early. Cadence and query are stated so the check is executable.

Item Cadence Source Baseline at 2026-07-27 Trigger
NAND contract-price change, q/q Monthly / quarterly TrendForce press centre +33–38% (1Q26) → +70–75% (2Q26) → +10–15% (3Q26E) Any negative print → evidence trigger B2 fires. A fourth consecutive print above +20% → thesis is wrong
TrendForce supply/demand balance Quarterly TrendForce 2026-07-21: "supply growth to outpace demand in 2027, easing in 2H27" A retraction or a push-out beyond 2028 → downgrade the mechanism
NAND conversion WFE Quarterly, with LRCX/AMAT/TEL results Equipment-maker earnings calls ~$40bn pulled forward, majority before end-CY2027; 2027E WFE $191bn (+28%) Conversion spend deferred or cut → the supply response is not arriving
Kioxia capacity commentary Quarterly Kioxia results Flash Ventures extended to 31 Dec 2034 (10-Q, 29 Jan 2026) Any greenfield announcement → supply response accelerates
Micron read-across Quarterly MU results Gross margin 84.6% (quarter ended 2026-05-28); ρ(SNDK, MU) = +0.78 A sequential MU gross-margin decline is the highest-value early read on SNDK, and it typically reports first
BIS / Federal Register Monthly federalregister.gov/api/v1/documents.json, agency industry-and-security-bureau Zero NAND-specific actions since 2024-01-01 (verified) Any NAND-specific export control → re-scope both directions
Nanya DRAM arrangement Quarterly SNDK 10-Q Notes 11/16; Nanya disclosures ~$1bn equity purchase settled 2026-04-08; committed annual volumes at variable pricing off Nanya's trailing ASPs Any disclosure sizing the DRAM cost exposure → this is an unmodelled margin-squeeze vector
SanDisk job postings Monthly ATS not yet located — Greenhouse, Lever and six Workday tenant/site combinations all returned 404/422 Not retrieved Locating the ATS is itself a research task; a hiring mix skewed to go-to-market vs process/engineering would be a counter-signal

Tier 4 — structural dates already in the record

Date Item Source Relevance
Continuous $6bn share repurchase, authorised 30 Apr 2026 10-Q MD&A A live right-tail risk to any short; also a value-destruction risk if executed at peak margins
Late 2026 HBF NAND die delivery Q3 FY26 call HBF has gone to zero mentions in prepared remarks for two quarters. A shipment announcement would reverse that decay
Early–mid 2027 HBF full system with controller Q3 FY26 call The only genuinely new category in the story
Q4 FY2026 (now) Stargate QLC eSSD enters revenue shipment Q3 FY26 call Watch the Datacenter line for the QLC contribution
Through FY2029 Kioxia building-depreciation prepayments: $17m (rest of FY26), $119m (FY27), $174m (FY28), $63m (FY29) 10-Q Note 11 Committed cash outflow; charged in the model
31 Dec 2034 Flash Ventures agreements expire (extended 29 Jan 2026 from 2029) 10-Q Note 11 Supply security is locked well beyond the forecast horizon
~FY2031 Last NBM contract expiry (longest term is five years from Q3 FY2026) Q3 FY26 call The date the contracted tranche fully rolls off and the model reverts to merchant treatment. Per the regime-change test, this is when the thesis gets retested from scratch

The one-line watch list

  1. 13 Aug 2026 Investor Day — the long-term gross-margin target. Everything else is secondary.
  2. The first sequential gross-margin decline (first checkable ~November 2026).
  3. Micron's next print — highest-correlation early read at ρ = +0.78, and it usually reports first.
  4. Reported RPO in the FY2026 10-K vs $41.6bn.
  5. A weekly close below the 200-day MA (~$823) — the Momentum Criteria entry condition.
