That puts the stock roughly 140% higher than a year ago, with a 52‑week range of $61.54 to $260.58. ^[1] Over just the past week, Micron has jumped about 14%, and year‑to‑date gains sit near 170%, according to Simply Wall St’s latest review of the stock. ^[2]

Below is a rundown of the most important Micron stock news and developments relevant as of November 30, 2025.

Micron Stock Near Record Levels After a Wild November

Micron’s rally in 2025 has been extraordinary, but November added an extra dose of drama.

Historical trading data show: ^[3]

All‑time high close: $253.30 on November 10, 2025
Recent intraday peak: $260.58 on November 17, 2025
Latest close (Nov 28): $236.48, with a daily range of $233.47–$238.10 and volume around 12.9 million shares

Over the past 12 months, Micron has delivered a ~141% return, outpacing most large semiconductor peers. ^[4] In a fresh analysis published this weekend, Simply Wall St notes Micron’s share price has risen 170.8% year‑to‑date and 14% in just the last week, driven by breakthroughs in memory technology, new supply deals and tight conditions in AI hardware supply chains. ^[5]

At the same time, research outlets including Insider Monkey and Zacks continue to highlight Micron as one of the top‑performing AI stocks heading into 2026, thanks to its leverage to data‑center and AI memory demand. ^[6]

New $9.6 Billion AI Memory Plant in Japan Signals Long-Term Ambition

The biggest new headline around Micron this weekend is strategic rather than purely financial: a major expansion in Japan.

According to multiple reports citing Nikkei, Micron plans to invest 1.5 trillion yen (around $9.6 billion) to build a next‑generation AI memory plant in Hiroshima, Japan. ^[7] Key details:

The facility will focus on advanced high‑bandwidth memory (HBM) chips used in AI accelerators and high‑performance data‑center systems.
Construction is expected to begin around May next year at an existing Micron site in Hiroshima, with shipments targeted around 2028. ^[8]
Japan’s Ministry of Economy, Trade and Industry (METI) is prepared to provide up to 500 billion yen in subsidies, as part of its broader effort to rebuild domestic semiconductor manufacturing and reduce reliance on Taiwan. ^[9]

The Japan project adds to Micron’s already large global expansion program and reinforces a core message: management expects AI‑driven memory demand to stay elevated for years, and is willing to commit heavy capital to secure its role in that ecosystem.

AI Memory Boom: Record Fiscal 2025 and Powerful 2026 Guidance

Beneath the stock price and headlines, Micron’s fundamentals show why so many investors are treating it as an AI infrastructure bellwether.

Record fiscal 2025

Micron’s fiscal year 2025 (ended late August) was a turning point. In a September investor presentation, CEO Sanjay Mehrotra highlighted that Micron: ^[10]

Grew revenue nearly 50% year‑over‑year to about $37.4–37.5 billion, a company record
Expanded gross margin by 17 percentage points to 41%
Generated operating cash flow of roughly $17.5 billion, more than double the prior year
Achieved all‑time highs in data‑center business, which now accounts for about 56% of total revenue ^[11]
Saw combined revenue from HBM, high‑capacity DIMMs and low‑power server DRAM reach about $10 billion, more than five times the prior year

In the June‑quarter (fiscal Q3 2025) alone, Micron delivered $9.3 billion in revenue, up 37% year‑over‑year and 15% sequentially, with non‑GAAP gross margin of 39% and net income of $2.2 billion. DRAM accounted for 76% of revenue, and the compute & networking business unit hit a record $5.1 billion in sales, helped by a nearly 50% sequential jump in HBM revenue. ^[12]

Strong Q1 2026 outlook

Looking ahead, Micron has set aggressive guidance for fiscal Q1 2026 (the quarter ending November, with results due December 17, 2025): ^[13]

Revenue guidance: around $12.5 billion, roughly 45% higher than the year‑ago quarter
Non‑GAAP EPS guidance: about $3.75, more than double last year’s $1.79 per share

Motley Fool and Nasdaq coverage emphasize that this acceleration is being driven by a favorable supply‑demand balance in DRAM, fueled by AI deployments. Industry data referenced in those reports indicate: ^[14]

DRAM prices have risen roughly 50% in 2025 so far, with server DRAM prices projected to double by the end of 2026
The global HBM market is forecast to grow from about $17 billion in 2024 to $98 billion by 2030
AI‑specific memory demand is expected to grow at ~30% annually through 2030, according to estimates cited from SK Hynix and Counterpoint Research

Micron’s own HBM ramp underscores the stakes: its HBM revenue reached nearly $2 billion in fiscal Q4 2025, implying an $8 billion annual run rate, and management expects to sell out its entire 2026 HBM3E supply within months. ^[15]

Price Hikes and PC Giants Confirm the Memory Shortage Story

Recent commentary from PC and server manufacturers has reinforced Micron’s bullish demand narrative.

A Barron’s piece, widely syndicated through outlets such as LiveMint and other financial news services, notes that Dell Technologies and HP Inc. are paying more for memory chips, a sign of how tight the supply picture has become. ^[16] That article ties Micron’s solid post‑Thanksgiving gain — roughly 3% in otherwise quiet trading — to the stronger‑than‑expected memory pricing revealed in Dell and HP earnings.

At the same time, Yahoo Finance and other outlets have highlighted that Micron stock climbed late last week as AI‑driven chip price hikes spread across the memory market, with both DRAM and HBM contract prices moving higher. ^[17]

GuruFocus adds another layer: a report on HBM4 pricing states that Micron shares jumped nearly 9% to about $237.50 recently, briefly touching an all‑time intraday high near $239.88, after news that SK Hynix had agreed to HBM4 prices around $560 per unit, more than 50% above current HBM3E levels. ^[18] The implication is straightforward — if AI customers accept sharply higher prices to secure leading‑edge memory, Micron’s margins and earnings power could exceed already bullish forecasts.

Analyst Community: Consensus Bullish, Targets March Higher

Wall Street is, on balance, strongly positive on Micron heading into 2026.

A MarketBeat summary published on November 28 notes that: ^[19]

Five analysts rate Micron as a “Strong Buy”, 26 as a “Buy” and only four as “Hold”
The average price target sits around $216 per share, based on a large sample of recent reports
Major banks including Stifel, JPMorgan, Morgan Stanley, Mizuho and Bank of America have raised targets in recent months

Among the more aggressive calls:

Morgan Stanley recently lifted its Micron target to $338 and reiterated an “overweight” rating. ^[20]
Mizuho boosted its target from $240 to $265 with an “outperform” view, according to a MarketBeat alert from November 28. ^[21]
Citi reiterated a “Buy” and kept its $275 target earlier in November, highlighting Micron’s roughly 159% year‑to‑date gain and arguing that the rise of generative AI is turning what used to be a cyclical memory business into a longer structural growth story. ^[22]

Those reports also point out that Micron currently trades at a price‑to‑earnings (P/E) ratio around the low 30s, with a PEG ratio near 0.5, and maintains a solid balance sheet with a current ratio above 2.5 and modest leverage. ^[23]

In short, the sell‑side view is that Micron remains a core AI beneficiary, and that even after a triple‑digit run investors may still not be fully pricing in multiyear HBM and data‑center demand.

Valuation Debate: Overvalued on Cash Flows, Undervalued on Growth?

Not everyone is comfortable with Micron’s current valuation, and November 30’s commentary captures that tension clearly.

Simply Wall St: DCF says “overvalued”

In a detailed piece dated November 29, Simply Wall St asks whether Micron’s 14% weekly rally and 170.8% year‑to‑date surge are justified. ^[24] Using a discounted cash flow (DCF) model that projects Micron’s free cash flow out to 2030, they estimate:

Intrinsic value: about $103.86 per share
Current price: roughly 127.7% above that estimate

On that basis, the article labels Micron “significantly overvalued” from a cash‑flow standpoint. ^[25]

…but multiples and growth metrics look attractive

The same analysis, however, paints a more nuanced picture when looking at valuation multiples: ^[26]

Micron trades at a P/E of about 31x, below the broader semiconductor industry average near 36x and far under a peer group average above 80x.
Simply Wall St’s proprietary “fair” P/E for Micron is around 43.6x, which would imply upside relative to the current multiple.
According to Nasdaq/Motley Fool, Micron’s trailing P/E is about 27x, its forward P/E roughly 13x, and its PEG ratio near 0.18, a level typically associated with stocks that are undervalued relative to their expected growth. ^[27]

In other words, valuation depends heavily on which lens is used:

DCF models that discount today’s cash flows against a history of cyclical memory markets tend to flash caution.
Growth‑adjusted metrics — using the AI‑driven revenue and earnings ramp expected over the next five years — suggest Micron may still be cheap for a high‑growth AI infrastructure name.

Simply Wall St’s community valuation range reflects this divide, with some investors pegging fair value below $100 and others north of $200 per share. ^[28]

AI Memory as the New Bottleneck — and Why That Matters for MU Stock

A separate analysis from The Motley Fool, republished via Finviz, frames Micron and SK Hynix as “quiet” AI winners precisely because memory bandwidth and capacity have become the bottleneck in modern AI clusters, rather than pure compute. ^[29]

Key points from that report:

Every new generation of AI GPUs uses more HBM and advanced DRAM, forcing cloud providers to allocate a larger share of infrastructure spending to memory.
The HBM market is projected to expand from $17 billion in 2024 to about $98 billion by 2030, while HBM’s share of total DRAM revenue could jump from 18% to 50% over that period. ^[30]
Due to capacity constraints, many hyperscalers are reportedly receiving only around 70% of their server DRAM orders, even after accepting price hikes of roughly 50% in late 2025. ^[31]

Micron’s strategy is to transform itself from a cyclical DRAM/NAND supplier into a full‑stack AI memory and storage company, ramping HBM3E and planning HBM4 to compete more directly with SK Hynix while leveraging its process‑node leadership (e.g., early ramp of its 1‑gamma DRAM node). ^[32]

To the extent this thesis holds — that AI memory remains in chronic shortage through much of the decade — Micron’s earnings and margin profile could look structurally different from past cycles, and that’s the crux of the bullish long‑term case.

What Micron Investors Are Watching After November 30, 2025

Heading into December, several catalysts and risk factors are front‑of‑mind for Micron shareholders:

Fiscal Q1 2026 earnings (Dec 17): Whether Micron can meet or exceed its ambitious revenue and EPS guidance, and how management updates its outlook for calendar 2026 AI demand and memory pricing. ^[33]
HBM supply and pricing: Updates on HBM3E and HBM4 ramps, including how quickly 2026 and 2027 capacity is being pre‑sold and whether price discipline holds after recent contract hikes. ^[34]
Japan megaproject milestones: Additional detail on the Hiroshima plant’s timeline, technology node, and subsidy structure as local authorities formalize support. ^[35]
AI capex cycles: Any sign that hyperscalers are moderating AI spending would be closely scrutinized, given Micron’s heavy data‑center exposure. Conversely, stronger cloud and enterprise AI budgets could reinforce the bullish scenario. ^[36]
Competition from SK Hynix and Samsung: Rivals’ HBM roadmaps and capacity expansions could influence Micron’s future market share and pricing power. ^[37]

For now, the picture on November 30, 2025 is clear: Micron sits at the intersection of a historic AI build‑out and a structurally tighter memory market, with Wall Street largely in its corner — but with valuation models starting to flash yellow after a meteoric run.
