See companies we've covered ›History and context
Micron Technology, Inc. is an American multinational semiconductor company that manufactures computer memory and computer data storage products, including dynamic random-access memory (DRAM), flash memory, High Bandwidth Memory (HBM), and solid-state drives (SSDs). Founded in 1978 in Boise, Idaho, Micron is the only major American computer memory manufacturer. It is one of the "Big Three" computer memory manufacturers, along with the South Korean companies Samsung Electronics and SK Hynix.
Micron marketed its consumer products under the brand Crucial, with the sub-brand Ballistix being used to denote products targeting gaming computers, until its disestablishment in 2026. Micron and Intel together created IM Flash Technologies, which produced NAND flash memory. It owned Lexar between 2006 and 2017.
Sanjay Mehrotra has served as president and CEO of Micron since 2017.
On May 26, 2026, Micron became the latest U.S. company to reach a US$1 trillion market capitalization, amid surging demand for its HBM chips.

What it actually sells Soon
A product-by-product guide to Micron Technology: what each one is, who buys it, and how much it brings in, in plain English and in the company's own terms. We're starting with the companies that are hardest to picture, like Broadcom.
Moat not rated yet
We haven't rated Micron Technology's moat. A rating needs at least five years of returns against the cost of capital, plus evidence for each of the five lenses.
How we rate moats ›Is it a good business at a fair price?
What each method implies
Ranges, not targetsThe five questions, and the price
Six checks from the annual reports. A flag marks a reason to dig deeper, not a verdict.
- 1. Is it growing?Within the guide
+36.9% a year
Revenue growth over 5–10 years
Revenue $27.7B in FY2021 to $133.2B in FY2026; +26.8% a year over 10 years. It fell in 1 of the last 5 years.
Sales have grown about 36.9% a year for five years, so each $1 of sales in FY2021 is about $4.81 now.
What to look for Steady growth, not one lucky year.

- 2. Is it profitable?Within the guide
74.6%
Operating margin (operating income ÷ revenue)
FY2026 operating margin. 5-year average 20.1%, range −37.0% to 74.6%.
Micron Technology kept about 75 cents of operating profit from each $1 of sales in FY2026.
What to look for Stable or rising. It's cleaner than net income, which one-off items and tax can distort.
Source: FY2026 10-K, filed 9 Oct 2026.
- 3. Is the profit real cash?Reason to dig deeper
$59.0B
Free cash flow (operating cash flow − capex), and FCF ÷ net income
FY2026 free cash flow: operating cash flow $89.7B less capex $30.7B. Over 5 years FCF was 59% of net income.
For every $1 of reported profit over 5 years, about $0.59 turned up as spare cash.
What to look for FCF positive and growing, and close to net income over time.
Source: FY2026 10-K, filed 9 Oct 2026.
- 4. Is it a good business?Within the guide
152.8% ROIC
Return on invested capital (ROIC); ROE for banks
FY2026 ROIC. 5-year average 36.8%; above 10% in 3 of 5 years. ROIC here is our calculation from the 10-K figures: operating income after tax (at the year's effective rate, or 21% where that rate is meaningless) over shareholders' equity plus borrowings less cash and short-term investments at the start of the year. Leases are left out.
Each $1 tied up in the business has earned about 37 cents a year after tax.
What to look for Clearly above the cost of capital (roughly 8–10%). Sustained 15%+ usually means a moat.
Source: FY2026 10-K, filed 9 Oct 2026.
- 5. Can it survive a bad year?Within the guide
Net cash $40.6B
Net debt ÷ EBITDA or ÷ FCF, plus interest cover
FY2026 year end: borrowings $2.8B, cash and short-term investments $43.4B. Operating income covers interest 937.2x.
Micron Technology holds more cash than it owes, so it could pay off its borrowings today.
What to look for Debt payable from about 3 years of FCF or less, interest covered many times.
Source: FY2026 10-K, filed 9 Oct 2026.
- 6. Is the price right?
5.9% FCF yield
FCF yield or EV/EBIT, and price against a cash-flow value
Market cap $1.0T. FCF yield 5.9% on FY2026 free cash flow. EV/EBIT 9.7x on FY2026 operating income.
At this price, each $100 of shares comes with about $5.89 of last year's spare cash.
What to look for Pay less than a cash-flow value estimate, with a margin of safety.

Crowd favourite or value trap?
Neither is a label we can put on a stock. These are signs worth looking into, each from a figure on this page.
Signs of a crowd-driven price
Meme stocks move on attention more than on results: big swings, a price far from cash-flow value, thin profits.
