A Sector-Wide Selloff, Not a Company Problem

Micron (MU) fell almost 20% this week, dragged down by a broad selloff across memory chip stocks rather than any change to its own business. The move followed a rough print from South Korean rival SK Hynix, which posted a 557% jump in quarterly profit but still missed Wall Street forecasts. That miss rattled investors and sent chip stocks sliding worldwide, since Micron trades closely with its memory peers.

The pullback also comes amid growing chatter about whether AI infrastructure spending can keep justifying today’s valuations. Several large tech names saw their multiples compress this week as investors questioned how quickly AI capital expenditure will translate into profit. Micron, still up sharply from where it traded a year ago, became an easy target for profit-taking.

MU Revenues (TIKR)

None of this changes Micron’s underlying story. Just five weeks ago, the company posted fiscal Q3 results that blew past expectations, with adjusted EPS of $25.11 versus estimates near $20.60 and revenue of roughly $41.5 billion, up about 345% from a year earlier. Management also guided Q4 revenue toward $50 billion, driven by insatiable demand for high-bandwidth memory, or HBM, the specialized chip stacks that feed AI accelerators.

CEO Sanjay Mehrotra told analysts on the June call that supply constraints aren’t going away soon. “We see tightness continuing beyond 2027,” he said, pointing to the years-long lead time needed to bring new fabrication capacity online. If MU stock stabilizes as the broader chip rout cools, this week’s drop could look more like a buying opportunity than a warning sign.

Is Micron Stock Undervalued?

MU Guided Valuation Model (TIKR)

Under valuation model assumptions realized through 8/31/28, the stock is modeled using:

  • Revenue Growth (CAGR): 90.7%
  • Operating Margins: 70.0%
  • Exit P/E Multiple: 5.1x

Based on these inputs, the model estimates a target price of $1,423, implying 92.6% upside and a 36.8% annualized return by August 2028.

Micron’s valuation looks unusual for a company growing this fast. Because chipmakers historically get treated as cyclical, Wall Street is pricing Micron at a forward P/E near 5x, far below what a business posting triple-digit revenue growth would normally command. That gap is the core of the bull case here.

Growth quality backs up the optimism. HBM capacity is sold out well into next year, and Micron has locked in roughly $100 billion of minimum contracted revenue through long-term supply agreements with major customers. That structure is designed to protect margins even if the memory market eventually cools, which historically has been the industry’s biggest risk.

Micron’s own history shows how dramatic this shift has been. Gross margin has jumped from below 40% a year ago to over 70% today, largely because HBM commands premium pricing that ordinary DRAM never did. Competitors like SK Hynix and Samsung are chasing the same demand, but neither has matched Micron’s pace of margin expansion this cycle.

The clearest way to see this story is a revenue and forward-estimates chart, ideally placed at the top of this section, showing the vertical jump in quarterly revenue since HBM shipments accelerated in 2025 and 2026.

Micron vs. SK Hynix and Samsung: The Margin Gap

Micron’s two closest peers in high-bandwidth memory are SK Hynix (SKHY) and Samsung, both of which are racing to expand HBM output. SK Hynix posted 557% profit growth in its most recent quarter, but the results still missed estimates, and its shares slumped 10% on the news, a sign that AI memory stocks across the board are being priced for perfection.

MU % Operating Margins vs SKHY vs Samsung (TIKR)

Operating margin is where the gap between the three shows up most clearly. Micron’s most recent quarterly operating margin came in at 80.4%, ahead of SK Hynix’s 76.3% and well above Samsung’s semiconductor division, which posted a 70.0% operating margin on record profit this quarter even as its mobile division swung to a loss. All three are benefiting from the same HBM supercycle, but Micron currently holds the profitability edge among the group.

The moat here isn’t just capacity. Micron’s HBM4 shipments already exceed $1 billion, and management has said it’s deliberately keeping HBM market share close to its overall DRAM share to avoid starving other product lines of wafer capacity. That discipline could matter if the AI memory boom eventually slows and pricing power becomes harder to defend against better-capitalized rivals like Samsung.

What’s Driving MU Stock Going Forward?

The most important near-term catalyst is Micron’s fiscal Q4 report, where management has guided for roughly $50 billion in revenue, a level that would mark another sharp step up from Q3. Investors will be watching whether pricing holds and whether HBM shipments keep climbing at the pace management has promised.

Capacity expansion is the next major theme. Micron’s Idaho fab is targeting first wafer output in mid-2027, while its newly acquired Tongluo site in Taiwan should begin meaningful shipments around the same time. A Singapore packaging facility and a new fab cluster in New York add to the pipeline, though none of these will meaningfully ease supply constraints before 2028.

Longer term, the durability of AI infrastructure spending remains the swing factor. If hyperscalers keep building data centers at the current pace, Micron’s take-or-pay contracts should protect both volume and pricing. But any slowdown in AI capital expenditure, or faster-than-expected capacity additions from SK Hynix and Samsung, could pressure the multiple that’s driving the current bull case.
