STX — Catalyst Calendar

Dated events only. Anything undated is marked DATE NOT CONFIRMED and must not be treated as scheduled. No date in this file is inferred from a pattern.

Date Event Source Why it moves the thesis

Product-cycle milestones with company-stated timing

Timing Milestone Source
June-2026 quarter ("the current quarter" as of the FQ3 call) Complete Mozaic qualification with the remaining two of the leading global cloud customers (75% covered at FQ3) FQ3'26 prepared remarks, CFO
2H CY2026 50% exabyte crossover on nearline HAMR drives FQ1'26 prepared remarks
Exiting CY2026 Majority of HAMR exabytes on 40TB drives (vs 30TB previously) FQ3'26 Q&A, clarified by CFO
End of FY2027 70% of nearline exabytes built on HAMR FQ3'26 Q&A, clarified by CFO
End of FY2027 Build-to-order contracts (configuration + pricing) run through this date FQ3'26 prepared remarks, CEO
Through CY2027 Nearline capacity "almost fully allocated" FQ3'26 prepared remarks, CEO
CY2028 and beyond "Actively engaged in strategic planning discussions" — not contracted FQ3'26 prepared remarks, CEO

The single most important dated risk

The CY2028 renewal. Allocation is covered through CY2027 and BTO pricing through FY2027. Every element of the structural thesis is contracted only to that boundary. The renewal negotiation will be visible in the FQ2–FQ3 FY2027 calls (roughly Jan–Apr 2027) — that is when the falsifier in STX_Research.md §8 becomes testable, and it sits inside the 12-month thesis horizon.

Peer-driven catalyst

WDC FQ4 FY2026 results — DATE NOT CONFIRMED, expected within days to weeks (WDC's FY2025 10-K was filed 2025-08-14 and its FQ1 FY2026 results were released 2025-10-30; the FQ4 FY2026 release has not been announced as of 2026-07-29). WDC's FQ4 guide is revenue $3.65bn and non-GAAP GM 51–52%. A miss on WDC's gross margin, or any WDC commentary on adding capacity, is a read-across risk to STX regardless of STX's own print.
