Key Takeaways
- Seagate’s earnings beat and robust guidance triggered a memory stock rally on Wednesday
- SanDisk shares climbed 7.8%, while Western Digital advanced 10.5% and Micron rose 4.7% during premarket hours
- The Wall Street Journal’s report about OpenAI falling short of growth projections sparked Tuesday’s decline
- Seagate’s 17.8% premarket surge provided confirmation that AI storage demand continues at healthy levels
- Wall Street anticipates another robust performance when SanDisk unveils fiscal Q3 results on April 30
SanDisk shares experienced a significant rebound during Wednesday’s premarket session following Tuesday’s AI-related market weakness. The momentum shift occurred after Seagate delivered impressive quarterly results that reassured the market about data storage sector fundamentals.
SanDisk advanced 7.8% to $1,080 before the opening bell. Western Digital posted gains of 10.5% to reach $432, while Micron Technology increased 4.7% to $528.12.
The previous day’s weakness followed a Wall Street Journal article indicating that OpenAI had fallen short of certain growth milestones. This news created uncertainty throughout AI-related investments, causing declines among memory and storage companies during that trading session.
Seagate reversed market sentiment quickly. The storage manufacturer exceeded expectations for both revenue and earnings, while providing fiscal fourth-quarter guidance that surpassed analyst projections. Seagate shares jumped 17.8% to $682 during premarket activity, recovering from a 2.8% decline the previous day.
Seagate’s performance delivered an important message to SanDisk shareholders and the broader memory sector: despite questions surrounding OpenAI’s metrics, overall demand for AI infrastructure storage continues to demonstrate strength.
Memory-focused equities have delivered exceptional returns throughout the current year. SanDisk accumulated gains of 322% leading up to Tuesday’s market close. Seagate advanced 110%, Western Digital climbed 127%, and Micron posted 77% returns.
Analyst community remains optimistic about future prospects. Melius Research analyst Ben Reitzes launched coverage of both Micron and SanDisk with Buy ratings on Monday. He communicated to investors that the current uptrend maintains additional upside potential, describing memory as “existential” for artificial intelligence expansion and projecting demand growth to accelerate “exponentially.”
D.A. Davidson initiated Micron coverage with a Buy rating on Wednesday, establishing a $1,000 price objective.
SanDisk Reports Quarterly Results Thursday
Investor attention shifts to SanDisk’s fiscal third-quarter financial results, scheduled for release on April 30. The company established high expectations with its previous quarterly disclosure.
During fiscal Q2, SanDisk recorded revenue of $3.03 billion, representing a 31% increase from the prior quarter and a 61% year-over-year improvement. GAAP net income reached $803 million, translating to $5.15 per diluted share.
The Q3 outlook captured significant market attention. SanDisk projected revenue ranging from $4.4 billion to $4.8 billion, with non-GAAP diluted EPS between $12 and $14. Management also provided gross margin guidance of 65% to 67%, representing substantial expansion from the 51.1% achieved in Q2.
Datacenter Segment Demonstrates Rapid Expansion
SanDisk’s datacenter operations have emerged as an increasingly important revenue contributor. Datacenter revenue expanded 64% sequentially during Q2, climbing to $440 million from $269 million in the preceding quarter.
Management attributed this growth to AI infrastructure development, semi-custom client demand, and major technology companies deploying artificial intelligence capabilities.
Market participants monitoring Thursday’s earnings conference call will concentrate on NAND flash pricing dynamics, whether datacenter growth sustained its trajectory through Q3, and executive commentary regarding the remainder of the fiscal year.
The earnings discussion is scheduled for 1:30 p.m. Pacific Time on April 30.
