What Happened?
Western Digital (WDC), the pure-play hard disk drive maker that completed its Sandisk flash memory spinoff in early 2025, delivered a structural earnings inflection in its fiscal second quarter, with EPS surging 78% year-over-year to $2.13 against a stock trading at $275.34, as 90% of revenue now ties directly to the data center infrastructure feeding the global AI buildout.
On January 29, CFO Kris Sennesael reported Q2 revenue of $3 billion, up 25% year-over-year, with gross margin expanding 770 basis points to 46.1%, driven by customer migration toward higher-density nearline drives, which are the large-capacity hard drives hyperscalers use to store AI training data and inference histories at scale.
The margin engine rests on UltraSMR, a software-defined recording technology that delivers 20% more storage capacity than conventional drives without added hardware cost, and WDC crossed 50% UltraSMR adoption within its nearline portfolio last quarter while guiding Q3 gross margin to 47%–48%, a trajectory that outpaces rival Seagate’s recent expansion pace.
Chief Product Officer Ahmed Shihab stated last February’s Special Day that “by the time we get to 100 terabytes, we could be 8x the performance of today’s drives,” anchoring a product roadmap that already has two of WDC’s top-five hyperscaler customers actively qualifying its next-generation 40TB ePMR drive and two more qualifying its HAMR platform, the laser-assisted recording technology that enables drives beyond 60TB.
Western Digital’s long-term model targets greater than $20 in EPS, greater than 50% gross margins, and greater than 30% free cash flow margins within three to five years, supported by a $4.0 billion buyback authorization approved February 3, firm purchase orders from its top seven customers through all of calendar 2026, and long-term supply agreements with three hyperscalers extending as far as calendar 2028.
Wall Street’s Take on WDC Stock
The Q2 FY2026 earnings beat, which confirmed gross margin expansion of 770 basis points year-over-year to 46.1%, validates the structural thesis that WD’s revenue mix shift toward high-density nearline drives is compressing the distance to 50%-plus gross margins faster than consensus expected.
TIKR estimates Western Digital’s EBITDA expanding from $2.78 billion in FY2025 to $4.67 billion in FY2026E and $6.78 billion in FY2027E, with margins widening from 29.2% to 37.4% to 43.3%, driven directly by UltraSMR adoption crossing 50% of the nearline mix and cost-per-terabyte declining approximately 10% annually.
Seagate (STX), a direct rival to WD in the nearline HDD market whose stock has surged 376% over the past year on the same AI storage demand wave, posted a FY2026E EBITDA margin of 34.7% against WD’s estimated 37.4%, a gap WD’s accelerating areal density roadmap and proprietary laser technology are positioned to widen further as capacity scales toward 100TB by 2029.
Wall Street has grown increasingly constructive on the name, with 16 buys, 4 outperforms, 6 holds, and 1 underperform across 23 analysts, placing the mean price target at $321.00, implying 16.6% upside from the March 27 close of $275.34, as analysts price in continued hyperscaler demand and the HAMR volume ramp targeted for the first half of calendar 2027.
The spread between the $170.00 low target and the $440.00 high target reflects a genuine binary around HAMR qualification timelines and pricing durability, with the low anchored to any slip in hyperscaler spending or a reversion to historical price-per-terabyte declines, and the high contingent on the Innovation Day roadmap executing on schedule.
What Does the Valuation Model Say?
The TIKR mid-case model targets $486.66 per share, representing a 76.8% total return and 14.3% annualized IRR through June 2030, anchored by an 18.7% revenue CAGR assumption and a 33.1% net income margin target that management’s own long-term model, presented February 3, explicitly brackets as a floor rather than a ceiling.
The market is pricing WDC as though its 79.6% EPS growth in FY2026E is cyclical; the long-term supply agreements extending to calendar 2028 confirm it is structural.
Firm purchase orders through all of calendar 2026 with WD’s top seven hyperscaler customers, combined with the $4.0 billion buyback approved February 3, directly underpin TIKR’s $486.66 target by compressing the share count while revenue scales toward $15.66 billion in FY2027E.
Management’s explicit commitment that HAMR gross margins will be neutral to accretive versus ePMR, stated at both the January 29 earnings call and the February 3 Innovation Day, signals that the technology transition does not reset the margin trajectory, making the EBITDA expansion story durable rather than front-loaded.
The single assumption at risk is pricing stability; if ASP per terabyte reverts to the historical mid- to high single-digit annual declines, the FY2027E EBITDA margin of 43.3% compresses materially and the TIKR $486.66 target becomes unreachable.
The Q3 FY2026 earnings report is the first clean read on whether mid- to high single-digit ASP-per-terabyte growth is tracking through calendar 2026 as guided, and gross margin printing above or below the 47%–48% guided range is the number to watch.
