Spinning off and surpassing its former parent in one year: SanDisk's market value is now 40 billion higher than Western Digital's.

SanDisk has completed a textbook-worthy value re-rating. The flash memory chip company, which only split off from Western Digital last year, now boasts a market cap that fully surpasses its former parent company, with a gap of over $40 billion. As of Tuesday’s market close, SanDisk’s market capitalization reached $208.26 billion, breaking the $200 billion threshold for the first time, while Western Digital’s market cap stood at $160.37 billion. Since the split in February last year, SanDisk’s share price has soared by 2794%, while Western Digital’s rose by 849% over the same period. The explosion of AI-driven storage demand, coupled with persistent supply shortages, are the core drivers behind the sharp rise in both companies’ valuations. At the time of the split, Western Digital’s market value was around $17 billion, and SanDisk’s around $7 billion. In just over a year, both companies have dramatically expanded their valuation, but SanDisk’s surge has been even more pronounced, completing a comprehensive surpassing of its former parent. Splitting Logic Realized, Flash Business Value Re-evaluated Western Digital spun off SanDisk in February last year, aiming to separate flash memory and hard drive businesses so that each could be more fully valued by the market. SanDisk’s main business is NAND flash products, which have high market volatility. Previously, as part of a diversified group, its growth potential was somewhat underestimated. After going public independently, with infrastructure construction for AI accelerating, the market’s demand for flash products sharply increased, giving SanDisk’s valuation logic a new lease of life. Currently, SanDisk’s market value ranks among well-known American companies. According to Dow Jones market data, companies with similar market caps include McDonald’s (about $203 billion), Verizon Communications (about $198 billion), and PepsiCo (about $212 billion). AI Demand and Supply Shortages Jointly Support High Price System What’s driving the soaring valuations of SanDisk and Western Digital is the rare phenomenon in the storage industry of both volume and price rising together. The large-scale deployment of artificial intelligence has significantly boosted demand for flash memory and hard drive products. SanDisk, Western Digital, as well as peers like Micron Technology and Seagate Technology, have all substantially raised product prices thanks to this. At the same time, supply shortages are expected to persist for months or even years, supporting high prices. New Business Model Reduces Cyclical Volatility, Enhances Earnings Visibility Last week, SanDisk revealed that it is transitioning to a "multi-year customer agreement" business model, requiring clients to make clear financial commitments, aiming to enhance earnings stability and reduce cyclical volatility. The company completed the signing of three customer agreements last quarter, and added two more agreements in the current quarter ending in June. Jefferies analyst Blayne Curtis pointed out in a research note last Friday that the new model gives SanDisk and investors greater business visibility. He said the three agreements signed last quarter "represent a minimum value" of $42 billion, and with storage supply remaining tight, this number is expected to "substantially" grow. He also noted that these agreements are "a strong signal that hyperscale cloud customers are willing to sign for high prices." Bernstein analyst Mark Newman believes that long-term agreements help achieve "long-term stability," and that lower cyclicality will bring "considerable economic benefits over longer time horizons," rather than just short-term quarterly performance.
