Micron Slips 4%: NVIDIA’s HBM Supplier Just Posted Record Results, So Why Is It Falling?

Micron (MU) posted record fiscal Q2 2026 revenue of $13.64B (up 56.6% YoY), crushing estimates with non-GAAP EPS of $4.78 beating by 21%, while its Cloud Memory Business Unit revenue nearly doubled to $5.28B.
The company also reported 66% gross margins, driven by HBM chips for NVIDIA (NVDA)’s AI GPUs.
MU stock fell 4% despite exceptional results because the market had priced in perfect performance before earnings and is now applying a supply-chain risk premium tied to geopolitical tensions in the Middle East.
A recent study identified one single habit that doubled Americans’ retirement savings and moved retirement from dream, to reality. Read more here.
Micron Technology (NASDAQ:MU) is down 4% in Thursday trading, with shares sliding to $445 from a prior close of $461.73. That's a head-scratcher on the surface, because last night Micron posted what CEO Sanjay Mehrotra called record results across the board.
Here's the paradox: the numbers were genuinely exceptional, the guidance was even better, and the stock is still selling off. This is Wall Street doing what Wall Street does, but there's more going on beneath the surface than a simple "sell the news" reflex.
Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.
Record Results, Adverse Reaction
Micron's fiscal Q2 2026 earnings, released Wednesday evening, were a blowout by any measure. Revenue came in at $13.64 billion, up 56.6% year over year, crushing the $12.88 billion consensus estimate. Non-GAAP EPS of $4.78 beat the $3.94 estimate by over 21%. GAAP gross margins expanded to 56.0%, up from 38.4% a year ago.
The Cloud Memory Business Unit was the standout, with revenue nearly doubling to $5.28 billion and gross margins hitting 66%. That's the HBM business, the high-bandwidth memory chips that power NVIDIA (NASDAQ:NVDA)'s AI GPUs. Furthermore, Micron's operating income surged 182% year over year to $6.14 billion, and free cash flow came in at $3.91 billion.
Micron's CEO Sanjay Mehrotra didn't mince words on the call. "In fiscal Q1, Micron delivered record revenue and significant margin expansion at the company level and also in each of our business units," he stated.
Micron followed that with guidance that was equally aggressive: Q2 FY2026 revenue guided to $18.7 billion, with non-GAAP EPS of $8.42 and GAAP gross margins expected at 67%.
Buy the Rumor, Sell the News
MU shares had already run hard into these results. The stock was trading around $285 at the start of the year and closed at $461.73 the day before earnings, a gain of 61.78% year to date. When a stock prices in perfection before the report, even perfection can disappoint.
Reddit picked up on this dynamic almost immediately. The top post on r/stocks after the earnings drop was titled "Micron Now Trading for 24X Next Quarter's Earnings While Growing Earnings by 900%," a headline that captures exactly the tension investors are wrestling with. The fundamentals are extraordinary, but the valuation had already moved to reflect them.
Pre-earnings sentiment on Reddit peaked at a score of 90 (very bullish) heading into Micron's report, with r/WallStreetBets dominated by YOLO options plays and realized-gains posts. By Thursday morning, that same sentiment had cooled to 67 (bullish but declining).
Retail traders had positioned heavily in calls, and many appear to have taken profits into the earnings pop. This pattern isn't new for Micron stock; looking at the last four quarters, three of four earnings beats resulted in a negative or near-flat same-day price reaction, despite a strong beat rate on estimates.
Geopolitics Piling On
The sell-the-news dynamic alone might have produced a modest pullback, but the broader semiconductor sector is getting hit today by a separate catalyst. Rising geopolitical tensions in the Middle East are sparking concerns about a potential helium supply shortage critical for chip manufacturing, dragging down chipmakers across the board. NVIDIA, AMD (NASDAQ:AMD), and Intel (NASDAQ:INTC) are all trading lower today; NVIDIA is off 1.04% on the session.
Micron stock carries the most negative ticker-specific sentiment score among its peers today at -0.419, a bearish reading despite the company's record results. That gap between fundamentals and price action reflects the market pricing in a supply-chain risk premium on top of the post-earnings reset.
What to Watch
Micron's longer-term story remains intact. HBM order books reportedly stretch into 2027, and NVIDIA's own most recent quarter showed record data center revenue driven by surging AI GPU demand, which flows directly into Micron's demand outlook.

Analyst consensus on Micron shares remains constructive, with 38 buy ratings, 3 holds, and just 2 sells, and a consensus price target of $432.49. In the coming days, watch for MU stock to either hold or break below the $440 level.
Data Shows One Habit Doubles American’s Savings And Boosts Retirement
Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.
And no, it’s got nothing to do with increasing your income, savings, clipping coupons, or even cutting back on your lifestyle. It’s much more straightforward (and powerful) than any of that. Frankly, it’s shocking more people don’t adopt the habit given how easy it is.
