The HDD Challenge That’s Casting a Shadow Over Micron’s $1,100 Dream

Micron guides to a record quarter with 260% revenue growth and sold-out HBM capacity, but shares fall 10% amid profit-taking and competitive fears from Western Digital's HDD pivot.

Micron Technology finds itself in an unusual spot. The memory-chip maker is guiding toward a record quarter with 260% revenue growth, its high-bandwidth memory (HBM) capacity is sold out into 2026, and analysts are tripping over each other to raise price targets. Yet the stock is heading south. Shares closed Monday at €585.40, handing investors a weekly loss of roughly 10% even as the year-to-date tally still shows a 117% gain. The culprit? A combination of profit-taking after a 12-month surge of almost 570% and an unexpected competitive threat from an old rival.

Western Digital’s HDD Pivot Rattles the AI Memory Narrative

The immediate trigger for the sell-off came from Western Digital, which is pushing new high-capacity hard-disk drives aimed at the AI data center. The company’s argument — that durability and data security can matter as much as raw speed in AI workloads — directly challenges the thesis that Micron’s SSDs and DRAM chips are the indispensable backbone of AI infrastructure. The mere possibility that HDDs could carve out a role in AI storage has unnerved investors who had priced Micron as a monopoly supplier of high-performance memory.

Seagate’s CEO Dave Mosely only added to the anxiety. He confirmed that Seagate is deliberately avoiding building new factories to prevent overcapacity — a discipline that normally supports memory and storage pricing, but that also underscores the industry’s cautious approach to expanding supply. That caution, however, runs counter to the explosive demand narrative that has fueled Micron’s rally.

Wall Street’s Bull Case Intact — and Getting Bolder

None of this has cooled the ardor of sell-side analysts. Melius Research on Monday lifted its Micron target to $1,100 a share, the highest on the Street and a 57% premium from current levels. Citi nearly doubled its own forecast to $840, while Deutsche Bank jumped to $1,000 and Mizuho raised its target to $740, up from $545. All point to rising DRAM prices and the HBM capacity crunch as the underpinning for Micron’s transformation from a cyclical semiconductor play into a structural AI winner.

Citi expects Micron to hike DRAM prices by 40% in the current quarter alone. Gartner projects a 125% increase for the full year. The company’s HBM production is already sold out through 2026, and industry shortages are expected to persist until at least 2028 because new fabs won’t come online quickly enough.

Record Sales and a 256GB Speed Leap

The fundamentals justify the optimism. Micron posted revenue of $23.86 billion in its latest fiscal quarter, a 196% jump from a year earlier, and management forecasts a record $33.5 billion in the current quarter — implying that 260% growth target. Gross margins and free cash flow also hit all-time highs. On the product front, the company has started shipping a new 256GB memory module for servers that runs 40% faster and consumes significantly less power than current generations.

CEO Sanjay Mehrotra has noted that key customers are receiving only half to two-thirds of their orders due to supply constraints, a dynamic that gives Micron considerable pricing power.

Samsung Strike, Conference, and the Valuation Question

Yet the stock’s valuation has become a sticking point. At a price-to-earnings ratio of roughly 34, Micron is no longer priced as a garden-variety memory manufacturer but as a high-growth AI beneficiary. With a looming strike at Samsung Electronics adding geopolitical risk and the specter of profit-taking after a monumental run, some investors are choosing to cash out.

New catalysts could arrive as early as Wednesday, when Micron’s management appears at the J.P. Morgan Global Technology Conference in Boston. The team is expected to provide detail on pricing strategy and capacity planning for the months ahead. Whether that will be enough to reverse the current dip — or whether the Western Digital HDD threat and broader semiconductor sell-off will keep the pressure on — remains the open question for a stock caught between a record-setting outlook and a market that has suddenly turned skeptical.
