This structure gives WDCthe abilitytoperiodicallyrenegotiatepricing,andmanagement implied that resets are staggered acrossquarters, creatingrepricing, incremental volume above the committed LTA amount that can be priced at more market-based levels,and non-nearline pricing tailwinds as NAND inflation makes HDDs relatively more attractive in overlapping use cases. there is still a bit more work to be done on yield, reliability,and quality. In the near term, WDC's roadmap is stll primarily drivenby next-gen ePMR and UItra SMR rather than HAMR, leaving it behind STX's HAMR-led roadmap.We continue to model better WDC still holds 1.7mn Sandisk shares,andmanagement intends to monetize the remaining stakevia a tax-free equity-for-equity swap before the end of CY26.Economically,this should function like a synthetic share buyback: instead of sellingtheSandisk shares forcashand separately repurchasing WDC stock,WDC would effectivelyexchangethe SanDisk equityvalueforits own equity, reducing the share count in a tax efficient way.
