Q1 FY2027 earnings recap

Western Digital fell in October 22 after-hours trading after releasing fiscal first-quarter 2027 results that evening.

Revenue reached $4.381 billion, rising 55% from $2.818 billion a year earlier and 17% from the prior quarter.
GAAP diluted EPS was $4.63 and adjusted diluted EPS was $4.64, versus $3.07 and $1.78 a year earlier.
Adjusted gross margin reached 58.1% and adjusted operating margin reached 49.1%.
Operating cash flow totaled $1.60 billion, while free cash flow was $1.38 billion.
Second-quarter guidance calls for $5.0–$5.2 billion of revenue, 60%–61% adjusted gross margin and $5.60–$6.00 adjusted EPS.
The quarterly dividend increased 17% to $0.175 per share, payable December 17 to holders of record on December 4.

Strong reported growth and a lower share price can coexist; cloud demand, pricing, customer concentration and expectations remain key risks.
