Cycle on Oct 5, 2026

I'll start this research cycle by checking open threads, prior notes, and pulling market data for the core memory-cycle names.

I have the lay of the land. Several watches have fire dates that have passed (Micron Taiwan strike vote ~Sep 30, Samsung NSEU merger today Oct 5, Micron FQ4 SCA deposit ~Sep 25) and MU's market view shows FQ4 results are out. Let me check what actually happened on those, plus the latest pricing commentary.

Rich results. Micron's FQ4 (reported Sept 30) is a landmark: 26 SCAs, $150B RPO, $12.7B customer deposits on balance sheet, 87% GM, >75% of 2027 output committed. The Taiwan strike vote concludes tomorrow (Oct 6). Now let me check the latest pricing commentary, Samsung's preliminary Q3, and the HBM4 negotiation state.

I'm continuing the cycle — fetching the key sources I'll cite so I have verbatim quotes before writing notes.

I have strong evidence on pricing, HBM4 negotiations, the Rubin de-spec, and the Micron labor/earnings story. Two quick checks before writing: the Samsung NSEU merger (fire date is today) and SK Hynix's Q3 reporting date.

SK Hynix reports Q3 on Oct 27 (Investing.com) — and notably its Q2 record profit *missed* forecasts and the stock slumped 10%. Let me verify the Samsung NSEU merger status, then write up findings.

I have all evidence in hand — now writing the four finding updates, reusing existing slugs for each continuing subject.

Two notes saved; the third call went out empty — writing the remaining two notes now.

All four findings are saved. Now recording the fired watch events, registering new forward-looking watches, and opening the one open question — all in parallel.

All records are in place. The cycle is complete — wrapping up.

Cycle complete. Here's what this research cycle found: ## Four findings updated (all continuing subjects, same slugs) **1. Pricing deceleration arc extends** — TrendForce's Sept 30 forecast puts 4Q26 conventional DRAM at +10-15% QoQ and NAND +15-20%, completing the arc: +90-95% (Q1) → +58-63% (Q2) → +13-18% (Q3) → +10-15% (Q4). The rate of increase has collapsed an order of magnitude while prices still set records. Crucially, the consumer side is already bending: PC brands are cutting SSD capacity per device, smartphone OEMs are buying minimum volumes, and mobile DRAM is at just +0-5%. Micron's own print (DRAM ASP high-teens, NAND +30%) is converging with the contract-market glide. **2. The 2027 HBM4 round hardened, didn't stall** — Last cycle's "buyer pushback" now looks like interim noise: Samsung is asking mid-to-high $4/Gb (3x+ HBM3E), TrendForce projects +121% HBM ASP for 2027 ($600 → ~$1,300 per 12-Hi 36GB stack), Micron says the vast majority of CY2027 HBM is locked at significant increases, and SK Hynix is reportedly removing price caps from LTAs. Counterweight: Bernstein cut its 2027 hike expectation and SK Hynix's target price. **3. Micron's SCA model at FQ4** — 26 take-or-pay SCAs (from 16), $150B RPO, $12.7B customer deposits on the balance sheet, >75% of 2027 output committed, agreements to 2031. But the tells are inside the print: content growth trimmed, a de-spec question from analysts, DIO up 9 days, capex going construction-heavy into 2028-29 cleanrooms — the everyone-adds-at-once pattern, third leg confirmed. And the market prices it as a cycle: 14.45x P/E on peak margins, RSI 75. **4. Rubin Ultra's 192GB fallback** — Nvidia's front-runner config cuts memory 33% vs Rubin; spot HBM3E trades at 4-5x contract ($2,100 vs $300-400). The biggest buyer engineering *less* memory into its flagship is what a shortage peak looks like from the demand side. ## Bookkeeping - **Resolved:** the FQ4 SCA-deposit watch (deposits arrived at $12.7B, below the ~$18B projection). **Updated:** the HBM4 buyer-resistance tripwire (kept open for final settlements). - **New watches:** Samsung prelim Oct 8 (first >₩100T quarter expected), SK Hynix Q3 Oct 27, consumer demand-destruction tripwire, and an HBM spot/contract premium collapse tell. - **Open question:** do take-or-pay contracts actually dampen the bust, or just relocate default risk to customers? - Still pending: Taiwan strike vote concludes tomorrow (Oct 6), NSEU merger unconfirmed.
