Western Digital (WDC) Delivers Strong Fiscal Q3 with +45% Revenue Growth

Key Takeaways

• Revenue reached $3.34 billion, surging 45% year-over-year and exceeding the consensus estimate of $3.25 billion.
• Non-GAAP diluted earnings per share (EPS) came in at $2.72, beating analyst expectations of $2.39 by $0.33 and nearly doubling from $1.38 a year ago.
• Non-GAAP gross margin crossed the 50% threshold, reaching 50.5% — up 1,040 basis points year-over-year — driven by favorable pricing and a mix shift toward higher-capacity drives.
• Cloud revenue represented 89% of total sales, rising 48% year-over-year as hyperscaler demand for nearline hard disk drives (HDDs) remained robust.
• Free cash flow hit $978 million, and the company announced a 20% dividend increase alongside $752 million in share repurchases.
• Q4 guidance called for revenue of $3.65 billion (±$100 million) and non-GAAP EPS of $3.25 (±$0.15), with gross margin expected to expand further to 51%–52%.

Earnings Context and Why It Matters

Western Digital's fiscal third quarter results landed at a pivotal moment for the data storage industry. The ongoing buildout of artificial intelligence (AI) infrastructure has unleashed a wave of demand for high-capacity HDDs, creating a supply-constrained environment that has given manufacturers like WDC significant pricing power. Coming off a fiscal second quarter that already showed 25% revenue growth, investors were watching closely to see whether the momentum could be sustained — and whether margins had further room to run. With shares having surged approximately 170% year-to-date before a summer pullback, this report served as a critical barometer for the durability of the AI storage narrative. I also checked comparable names in the sector using Tickeron’s AI Screener to put these results in broader context.

Breaking Down the Reported Results

WDC reported fiscal third quarter 2026 revenue of $3.34 billion for the period ended April 3, 2026, up 45% from $2.29 billion in the same quarter last year and above the $3.25 billion consensus. Non-GAAP gross margin expanded to 50.5%, compared to 40.1% a year ago and 46.1% in the prior quarter, reflecting sustained pricing gains and an ongoing shift toward higher-capacity enterprise drives.

Non-GAAP diluted EPS reached $2.72, nearly double the $1.38 reported in the year-ago period and comfortably ahead of the $2.39 consensus estimate. GAAP diluted EPS was $8.20, boosted by a $3.1 billion debt reduction tied to the monetization of SanDisk shares. Operating income on a non-GAAP basis rose 116% year-over-year to $1.29 billion, translating into an operating margin of 38.6%. The company shipped 222 exabytes during the quarter, up 34% year-over-year, including over 4.1 million drives of its latest-generation EPMR (energy-assisted perpendicular magnetic recording) products with capacities up to 32 terabytes.

For the fiscal fourth quarter, management guided to revenue of $3.65 billion (±$100 million), representing approximately 40% year-over-year growth at the midpoint, with non-GAAP gross margin expected to improve to 51%–52% and non-GAAP EPS projected at $3.25 (±$0.15).

Market Reaction and Investor Sentiment

WDC shares experienced volatile trading in the weeks surrounding the Q3 report. While the stock had rallied dramatically through the first half of 2026, it pulled back roughly 40% from its June peak by late July as broader AI-related names faced pressure and investors questioned whether elevated valuations across the storage sector had become stretched. Analysts remained broadly constructive: Wedbush raised its price target to $650, Morgan Stanley pointed to conservative margin guidance leaving room for upside, and Citigroup maintained a price target as high as $800. Still, the post-report period highlighted a key tension — strong fundamentals were largely priced in, and the market had become increasingly attuned to any signal that the supply-demand imbalance might be easing. Heading into the Q4 report in August, sentiment will likely hinge on whether gross margins continue to expand at the pace management has guided. One thing that stands out from reviewing recent patterns is how sentiment can shift quickly even with solid results.

Forward Outlook and Key Factors to Monitor

Looking ahead, several themes will shape the investment case for WDC. First and foremost is the trajectory of gross margins. The Q4 guidance for 51%–52% non-GAAP gross margin implies continued sequential improvement, but the pace of expansion — and whether the company can sustain margins above 50% — will be closely scrutinized. Pricing power remains the central pillar of the bull case, and any commentary suggesting that the tight supply environment is beginning to loosen would carry outsized weight.

A second factor is the company's technology roadmap. Western Digital is progressing with qualifications for its HAMR (heat-assisted magnetic recording) drives across multiple customers, with 40-terabyte EPMR products expected to enter volume production in the second half of calendar 2026. The successful ramp of these higher-capacity platforms will be essential to maintaining the favorable product mix that has driven margin gains.

Investors should also monitor the balance between capital returns and reinvestment. The company returned $2.2 billion to shareholders since launching its capital return program, including a newly increased dividend of $0.15 per share. At the same time, continued investment in head and media manufacturing capacity is needed to meet multi-year demand commitments. Multi-year long-term agreements (LTAs) extending into 2028 and 2029 provide revenue visibility, but execution on both the technology and manufacturing fronts remains critical. Finally, the heavy concentration of revenue in the cloud segment — 89% of total sales — means that any shift in hyperscaler spending patterns could have an amplified effect on results. I’m watching this closely as the next few quarters unfold.
