What Is Western Digital's Investment Narrative?

For Western Digital, the big picture you need to buy into is that AI-era data storage will increasingly favor very high-capacity, power-efficient hard drives, and that the company can turn its technology roadmap into durable earnings, not just headlines. Innovation Day sharpened that story: qualifying 40TB drives with hyperscalers, a path to 100TB, and an intelligent software layer all aim to deepen Western Digital’s role in AI infrastructure while justifying its richer valuation after a very large 1-year total return. In the near term, key catalysts remain execution on Q3 guidance, continued demand from cloud customers, and actual customer adoption of the new HDD and platform features. The expanded US$6.00 billion buyback adds support, but also raises the stakes if AI-driven storage spending slows or if these ambitious roadmaps slip.

However, one execution risk around those ultra-high-capacity AI drives is easy to underestimate. Western Digital's shares are on the way up, but they could be overextended by 9%. Uncover the fair value now.
