Sandisk's $15.5B Buyback: A Bullish Signal for SNDK Stock
💡 Key Takeaway
Sandisk's massive buyback and contracted revenue visibility suggest the stock, despite its surge, still has room to run in the AI storage boom.
What Happened: Sandisk's Buyback and Stellar Growth
Sandisk (SNDK) has been on a tear since its spin-off from Western Digital in February 2025, with shares up over 3,400% since then and 429% in 2026 alone. The company just announced a massive $15.5 billion share buyback program, signaling management's confidence that the stock is still undervalued.
In its fiscal Q3 2026, Sandisk's board authorized a $6 billion buyback, and management quickly deployed $4.5 billion in Q4. With only $1.5 billion left, they added another $14 billion, bringing total authorization to $15.5 billion. This aggressive repurchase plan is a strong vote of confidence in the company's future.
The company's financials are staggering: revenue grew 175% to $20.3 billion in fiscal 2026, with Q4 revenue up 372% year-over-year. Data center segment revenue soared 437% year-over-year. Gross margins expanded to nearly 85%, and free cash flow conversion is consistent.
Sandisk has also secured eight multiyear supply contracts with a minimum revenue floor of $93.9 billion, backed by $16.5 billion in prepayments. This provides unprecedented revenue visibility and pricing protection for a memory company.
Despite the parabolic rise, the stock trades at a forward P/E of just 6 based on fiscal 2027 EPS estimates of $212. This is modest compared to other AI chip stocks, suggesting the market hasn't fully priced in the company's growth potential.
Why It Matters: AI Storage Demand and Valuation
Sandisk is a critical player in the AI infrastructure build-out, providing high-capacity NAND flash storage for enterprise SSDs used in hyperscale data centers. As AI workloads explode, the demand for storage is surging, and Sandisk is well-positioned to capitalize.
The buyback is a powerful signal that management believes the stock is undervalued, even after its massive run. By reducing share count, they're boosting EPS and showing they have confidence in future cash flows. This often precedes further stock price appreciation.
Sandisk's new business model with long-term contracts and prepayments reduces the cyclicality typical of memory companies. This could lead to a re-rating of the stock, as investors may be willing to pay a higher multiple for more predictable earnings.
Compared to peers like NVIDIA (NVDA), Sandisk's forward P/E of 6 is significantly lower, making it an attractive value play in the AI supply chain. If the company continues to execute, valuation expansion seems likely.
However, risks remain: memory markets are historically cyclical, and a downturn could hurt. But with contracted revenue floors and strong demand, Sandisk appears better insulated than in past cycles.

Bobby Insight
Buy Sandisk stock with a 2-year horizon, as the buyback and revenue visibility support further gains.
Sandisk's forward P/E of 6 is too low for a company growing revenue 175% annually with contracted revenue floors. The buyback signals management's confidence, and the AI storage demand is secular. Risks include memory cyclicality, but the new business model mitigates that. I expect valuation expansion as earnings grow.
