Research note — Fiscal year ends early July (FY2026 ended July 3, 2026); SanDisk flash business was spun off, so WDC is HDD-only. The Q4 press release has no end-market table; quarterly Cloud share read from the presentation was ambiguous (89%-90%), so the 10-K annual 89% figure is used. No Q1 FY2027 earnings date listed as of 2026-09-17.
