WDC

Post-separation, WDC is a pure-play hard-disk-drive maker after distributing 80.1% of Sandisk (Flash) on Feb 21, 2025 and presenting results on a continuing-operations basis. The HDD business levered to 'cloud and hyperscale data center markets' (per the MD&A) is in a powerful cyclical upswing: FY2025 revenue rose 50.7% to $9.52B, operating income jumped 679.2% to $2.33B (24.5% operating margin), net income swung to $1.89B (+336.7%), EPS reached $5.12, and ROE hit 35.6%. Cash generation followed — operating cash flow of $1.69B (+675.2%) against just $412M of capex — and the balance sheet deleveraged hard (long-term debt down 56.3%). On the business alone, this is a high-quality, well-run cyclical at the top of its game.

The problem is price, not quality. At $746.23 the stock trades at 145.7x trailing EPS and 27.2x sales — multiples that would be rich for a hyper-growth software name, let alone a capital-intensive, commoditized HDD manufacturer. Critically, that 145x P/E sits on what looks like peak-cycle earnings: the same business posted a $1.68B loss in FY2023 and a $798M loss in FY2024. Cyclicals are most dangerous when they look strong, and here there is no margin of safety even at the peak — the market is pricing a permanent, AI-driven storage supercycle that the industry's own history says is not guaranteed. A normalized mid-cycle valuation (roughly 4x sales / ~20x peak EPS) lands near $110, far below the current quote, which frames the downside if multiples merely revert toward sane levels.
