SanDisk's Performance Turnaround Revealed by SEC Filings: What Has Changed?

Flash memory maker SanDisk Corporation (NASDAQ: SNDK) disclosed its preliminary results and financial position for the third quarter of fiscal 2026 in an 8-K filing with the U.S. Securities and Exchange Commission on April 30. The company reported revenue of $5.95 billion, a 251% increase year-over-year and a 97% rise sequentially. GAAP net income was $3.615 billion, or $23.03 in diluted EPS, marking a dramatic turnaround from a prior loss. GAAP gross margin surged from 22.5% to 78.4%, driven by a larger share of data-center customers and improved pricing. SanDisk also highlighted its shift to multi-year contract revenue models, the full repayment of long-term debt, and board approval of a share-repurchase program. For the fourth quarter of fiscal 2026, the company issued guidance of $7.75 billion to $8.25 billion in revenue and non-GAAP diluted EPS of $30 to $33, underscoring a strong outlook.

Headquartered in Milpitas, California, SanDisk specializes in NAND flash and solid-state drives. After being acquired by Western Digital in 2016, it spun off its flash business and re-listed on Nasdaq under the ticker SNDK on February 24, 2025. Under the reorganization, Western Digital focuses on hard disk drives while SanDisk oversees NAND-based storage, consumer and enterprise SSDs, memory cards, and USB flash drives. Since the split, SanDisk has targeted high-value flash for data centers and AI infrastructure as its core growth engine, regularly updating the market through SEC disclosures and investor communications.

To meet surging AI demand, SanDisk has expanded multi-year supply agreements with major hyperscale data-center customers and is collaborating with SK hynix to develop high-bandwidth flash technology, aiming to deliver a prototype by year-end 2026. In the consumer market, the company introduced its 2026 “Optimus” SSD lineup, rebranding and replacing Western Digital’s color-coded SSD series with high-performance options for gamers and content creators. Meanwhile, former parent Western Digital is gradually divesting its remaining SanDisk shares post spin-off to conclude their equity ties. Market observers are watching closely to see whether SanDisk’s strong results and contract-based business model will justify a standalone revaluation of its corporate value.
