Parnassus Mid Cap Growth Fund Ian Sexsmith, Robert Klaber | “SanDisk was a top contributor in both the quarter and the year as the ongoing AI megatrend drove strong demand for memory and storage, while industry supply growth remained constrained. Shares surged as pricing and utilization improved, benefiting from rising data center and AI workloads that require high-performance NAND storage. Management execution and favorable industry dynamics supported exceptional returns, prompting the Fund to trim the position after the sharp rally to diversify exposure. BSD Analysis: SanDisk historically represented the intersection of storage demand and semiconductor innovation. Flash memory cycles were brutal but instructive. IP around NAND and controller technology created differentiation. Pricing volatility dominated sentiment more than fundamentals. Storage demand only grew more mission-critical over time. Investors underestimated content growth per device. Operational leverage cut both ways. This was silicon infrastructure before infrastructure was fashionable. Cycles punished impatience, not relevance.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
