Company Reports

Western Digital’s fiscal first-quarter revenue rose 55% year over year to $4.4 billion, beating guidance by the widest margin since the SanDisk split. This was entirely driven by pricing. The second-quarter revenue guide was 13% above FactSet consensus.

Western Digital leads the hard disk drive market. This market is concentrated, with only three players remaining: Western Digital, Seagate, and Toshiba. Seagate and Western Digital have jostled back and forth for top share over the past decade, while Toshiba remains a distant third. Key end markets are phasing out HDDs in favor of solid-state drives, but we still see a future for HDDs in data centers. Total cost of ownership still favors HDDs over SSDs for large workloads where controlling costs is paramount, but immediate read access is less important. This is commonly referred to as nearline storage, which we expect will make up almost all of Western’s business over time.

We are relaunching our coverage of Western Digital after the spinoff of its NAND memory business SanDisk, with a fair value estimate of $41 for the stand-alone company. With shares trading at $49 as of writing, we think they are a bit expensive. We retain our no-moat, High Morningstar Uncertainty, and Standard Capital Allocation Ratings for the firm.

Western Digital is a leader in both of the pre-eminent data storage markets: hard disk drives, or HDDs, and NAND flash memory. We think Western's position in these markets paves the way for a strong top-line growth trajectory over the next five years, but believe these markets feature commoditylike products and massive investment requirements that leave Western vulnerable to cyclical downturns and prevent it from carving out an economic moat.

Western Digital's December-quarter revenue rose 41% year over year and 5% sequentially to $4.29 billion. Management's outlook for the March quarter calls for a sequential revenue decline of 10%, at the midpoint, and implies more than 600 basis points of margin compression.
