Western Digital kicked off fiscal 2027 the way its investors needed it to: with a beat across the board and a forecast that says the AI storage boom is still accelerating. The hard-drive maker reported $4.38 billion in revenue for its first fiscal quarter, comfortably ahead of the $4.16 billion Wall Street expected, as cloud customers keep buying capacity at a record pace.

Adjusted earnings came in at $4.64 per share against estimates of $4.10 — up 161% from a year ago. Adjusted operating income hit $2.15 billion, a 49.1% margin that dwarfs the 28.1% the company posted in the same quarter last year. Non-GAAP gross margin expanded to 58.1%, and the free-cash-flow margin jumped to 31.4% from 21.3%.

The report landed after the US market close on Wednesday, October 22, and it carries extra weight because Western Digital's stock had been under pressure — the shares fell roughly 16% in the prior week and closed Wednesday down more than 6% at $354.19, as investors braced for a guide-down.

Guidance says the boom has room to run

There was no guide-down. Western Digital told investors to expect about $5.1 billion in revenue next quarter, well above the $4.58 billion consensus, with adjusted earnings of $5.80 per share against estimates of $4.82. If it hits those numbers, it will mark the company's biggest quarter on record.

Cloud customers remain the engine: the segment generates roughly 90% of Western Digital's revenue, and the company's order books are filling as hyperscalers race to store the flood of data that AI training and inference produce. On average, Bank of America expects the price per terabyte to rise 24% year over year — pricing power the industry has rarely seen.

A dividend hike signals confidence

Management also raised the quarterly dividend by 17% to $0.175 per share, a move companies make only when they are confident about future cash flow. "Fiscal 2027 is off to a strong start, with results exceeding expectations, driven by robust customer demand and disciplined execution," CEO Irving Tan said in the release, pointing to growing demand for storage and deeper customer relationships.

The one yellow flag: inventory days outstanding rose to 88 from 80 in the previous quarter, suggesting the company is building stock into a cooling-but-still-strong demand picture. That number will be the thing to watch next quarter — if demand stays hot, the extra inventory just means more drives ready to ship.

For a company that has ridden the AI infrastructure wave to a market cap north of $140 billion, this quarter answers the only question that mattered: is the data-center demand still there? The answer, at $5.1 billion in forward guidance, is yes.
