Why did GAAP operating income swing so dramatically from a loss to a $2.3 billion profit?

The prior-year figure included a $291 million litigation charge, $209 million in business realignment charges, and a $(403) million operating loss. In FY25, GAAP operating expenses fell 38% to $1.36 billion, aided by a $198 million litigation reversal and lower SG&A, while gross profit rose to $3.69 billion on much higher revenue. The Flash business is now reported as discontinued operations, so the comparison reflects continuing HDD results.

How much of the GAAP earnings reflects non-operating items tied to Sandisk?

Significantly. The company recorded a $772 million loss on its retained Sandisk interest for the year and a $100 million loss on debt extinguishment, which pushed GAAP interest and other expense to $1.20 billion. GAAP diluted EPS for the full year was $4.45, versus non-GAAP diluted EPS of $4.93 for FY25 as reported in the non-GAAP reconciliation.

What is the outlook for the coming quarter, and what drives it?

For fiscal Q1 2026, management guided to revenue of about $2.70 billion (+/- $100 million), up roughly 22% year over year at the midpoint, with non-GAAP gross margin of 41%-42%, operating expenses of $370-$380 million, and non-GAAP EPS of $1.54 (+/- $0.15) on about 363 million diluted shares. Management attributed the momentum to Cloud demand, which it describes as its largest addressable market.

How is the company returning capital to shareholders?

The board declared a $0.10 per share cash dividend payable September 18, 2025 to holders of record as of September 4, 2025, and authorized a $2.0 billion share repurchase program. In Q4, the company repurchased $149 million of common stock and paid $44 million in dividends. Management framed these actions as reflecting confidence in the company's long-term cash generation.

Are these results final, and what risks should investors monitor?

The figures are preliminary and unaudited. The company warned that the 10-K may differ due to closing procedures, final adjustments, and the independent auditor's review. Key risks cited include tariffs and trade restrictions, demand volatility, competition, supply chain disruptions, the level of debt, and the potential reduction or discontinuation of dividends or buybacks.

WDC 8-K: Earnings & Results

01—Abstract

Summary

Summary of the 8-K filed July 30, 2025. Cited figures are marked; the original filing is the authoritative source.

Western Digital reported fiscal fourth quarter and full-year 2025 results (quarter ended June 27, 2025), showing strong top-line momentum and a sharp improvement in profitability.

Q4 revenue was $2.61 billion^a, up 30% year over year, with GAAP gross margin of 41.0% (up 620 bps Y/Y) and non-GAAP gross margin of 41.3%. GAAP diluted EPS was $0.67 and non-GAAP diluted EPS was $1.66. Fiscal 2025 revenue reached $9.52 billion, up 51% year over year, and GAAP operating income swung to $2.33 billion from a $(403) million loss the prior year, reflecting the separation of the Flash business into Sandisk on February 21, 2025, which is now presented as discontinued operations.

Cash generation and capital allocation were central to the message. Operating cash flow for the quarter was $746 million^b and free cash flow was $675 million; for the full year, free cash flow was $1.43 billion. Management said it reduced debt by $2.6 billion during the quarter, initiated a cash dividend of $0.10 per share (payable September 18, 2025), and authorized a $2.0 billion share repurchase program.

Balance sheet debt fell substantially, with long-term debt of $2.49 billion^c and current portion of $2.23 billion at fiscal year-end versus $5.68 billion long-term a year earlier. For fiscal Q1 2026, management guided to revenue of about $2.70 billion (+/- $100 million), non-GAAP gross margin of 41%-42%, and non-GAAP EPS of $1.54 (+/- $0.15), citing strength in Cloud demand. Investors should note that results are described as preliminary, the GAAP figures include sizable non-operating items (a $772 million loss on the retained Sandisk stake for the year and a $100 million loss on debt extinguishment), and the full-year GAAP tax line was a benefit of $513 million.
