Sandisk Stock Soars as Micron's Earnings Spark Optimism

Sandisk stock jumped over 11% on Thursday morning. The surge was directly triggered by a blockbuster earnings report from its archrival, Micron.

Micron reported fiscal third-quarter results that smashed Wall Street's expectations. Analysts had predicted earnings of $20.78 per share on $35.8 billion in sales. Instead, Micron earned $25.11 per share, and its sales quadrupled year-over-year to $41.5 billion.

This performance has investors looking ahead to Sandisk's own earnings report, which is scheduled for late August. Analysts are already forecasting Sandisk's earnings to more than double sequentially to $33.72 per share.

The logic driving Sandisk's stock price higher is straightforward: if Micron could deliver such stunning growth in the quarter ending in June, then Sandisk—with two more months of favorable market conditions—should be poised for an equally impressive result.

This news matters because it confirms the powerful, long-term tailwinds for the memory chip sector, particularly from artificial intelligence. Micron's CEO stated that the AI revolution is driving record demand, and the company is investing heavily to keep up.

Crucially, Micron is achieving operating margins above 80% on its products. The CEO also indicated that supply is unlikely to catch up with demand anytime soon, suggesting these favorable pricing conditions will persist.

Perhaps most important for future profits is the industry's shift to long-term contracts. Both Micron and Sandisk are locking in these high prices through Strategic Customer Agreements, which helps protect their margins even if the market eventually balances.

For investors, this means the earnings surge for Micron—and the anticipated surge for Sandisk—isn't a one-time event. It's supported by structural changes in demand and pricing that could lead to sustained profitability. The sector's fortunes are now deeply tied to the long-term growth of AI.
