Key Takeaways

  • WDC posted $4.4 billion in revenue, a 58.1% gross margin, $4.64 EPS and $1.4 billion in free cash flow.
  • WDC expects fiscal Q2 revenue of $5.1 billion and EPS of $5.80, with gross margins projected at 60-61%.
  • WDC benefits from AI-driven storage demand and long-term customer visibility but faces execution risks.

Western Digital Corporation (WDC - Free Report) delivered stronger-than-expected first-quarter fiscal 2027 results, with $4.4 billion in revenue, a 58.1% gross margin, EPS of $4.64 and $1.4 billion in free cash flow. Management highlighted extended multi-year customer visibility and a technology-led supply strategy focused on increasing areal density rather than expanding production capacity.

For the fiscal second quarter, WDC expects revenue of $5.1 billion (+/-$100 million), gross margin of 60-61% and EPS of $5.80 (+/- 20 cents). It also anticipates higher qualification-related operating expenses and plans to invest in heads, media and automation to support ePMR technology and the planned HAMR ramp and qualifications in calendar 2027.

WDC’s shares have gained 173.7% in the past year compared with the Zacks Computer-Storage Devices industry’s rise of 176%. The stock has outpaced the Zacks Computer & Technology sector and the S&P 500’s growth of 11.7% and 11.1%, respectively.

WDC operates in a competitive, AI-driven storage market alongside HDD leader Seagate Technology Holdings plc (STX - Free Report) and other storage players, including NetApp, Inc. (NTAP - Free Report) and WDC’s flash spinoff, Sandisk Corporation (SNDK - Free Report) . Over the same period, STX, NTAP and SNDK gained 171.3%, 83.9% and 601.5%, respectively.

The stock is gaining investor traction as demand for data storage continues to rise alongside AI, cloud computing and the expansion of hyperscale data centers. Strong quarterly earnings can signal improving business momentum, but investors must also consider valuation, future demand, profit margins and the possibility that positive expectations are already reflected in the share price.

The key question is whether WDC’s strong fiscal first-quarter results support further growth or whether investors should hold or take profits.

Why is WDC Benefiting From AI Growth?

As AI infrastructure expands, demand for nearline HDDs, the drives used for large-scale enterprise and cloud storage can increase along with the growth of stored data. Western Digital supplies high-capacity HDDs used by cloud service providers and hyperscale data centers. HDDs remain attractive for storing large quantities of information economically, even as solid-state drives serve performance-sensitive applications.

Western Digital continues to benefit from strong AI-driven storage demand, with its technology roadmap and pricing strategy supporting long-term growth. The company is ramping up 40TB ePMR drives ahead of schedule, while HAMR qualification is underway, with volume shipments expected in the first half of 2027. Demand across cloud, enterprise, neocloud and AI markets remains robust, with customer visibility extending to 2030. WDC is also benefiting from favorable pricing, with average price per terabyte rising 28% year over year, while exabyte shipments increased 22%.

Management expects shipment growth to accelerate as new platforms ramp, supported by demand for higher-capacity drives ranging from 32TB to more than 55TB. The company is prioritizing areal density improvements over unit-capacity expansion, leveraging its in-house head and media development capabilities to strengthen its competitive position and avoid supply oversaturation. Long-term agreements, higher-capacity products and efficient supply-chain management are expected to support pricing and margins.

Moreover, WDC plans to invest in R&D and manufacturing, with capital expenditures generally targeted at 4-6% of revenue. Its strong balance sheet, $0.5 billion net cash position and 17% dividend increase further reinforce its financial position. Emerging opportunities in AI inference, video streaming, autonomous vehicles and robotics could provide additional growth avenues as demand for high-performance storage expands.

What are the Key Risks for WDC Investors?

Despite its strong quarterly performance, Western Digital faces several execution and market risks. Rising DRAM, NAND and other input costs could slow cost-per-terabyte reductions, while delays in ePMR and HAMR qualifications or manufacturing ramp-ups could constrain exabyte growth. Higher investments in HAMR heads, media and automation may also push CapEx above its long-term target range.

Although tight supply and strong demand support pricing, limited capacity restricts WDC's ability to fully meet customer needs, while the current pace of ASP increases may eventually moderate.  Competitors, including Toshiba and Seagate, could influence pricing, supply availability and market share. Any increase in industry capacity could eventually put pressure on Western Digital's margins.

In addition, emerging opportunities in high-bandwidth drives and physical AI remain uncertain, and WDC's heavy reliance on cloud customers leaves it exposed to potential slowdowns in hyperscale, neocloud and AI infrastructure spending. Large cloud customers represent an important source of demand. Changes in their infrastructure budgets or purchasing strategies could materially affect revenue. Overall, sustained growth depends on favorable pricing, disciplined supply conditions and successful execution of the ePMR-to-HAMR transition.

Investment Verdict: Hold WDC Stock Now

WDC delivered substantial revenue growth, margins and higher earnings. The results reflect strong demand for high-capacity HDDs, particularly from cloud and data center customers. Its fiscal second-quarter guidance further strengthens the bullish case. Nevertheless, any slowdown in cloud spending, pricing pressure, or manufacturing challenges could affect actual performance. Investors should monitor gross margins, HDD pricing, customer demand, competitive supply and free cash flow in upcoming quarters.

Carrying a Zacks Rank #3 (Hold) at present, the stock appears to be treading the middle of the road, and new investors could be better off if they trade with caution. You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
