This backdrop helps frame why investors are paying close attention to the stock's price moves and what they might imply for risk and potential reward.
• On Simply Wall St's valuation framework Micron Technology scores 3 out of 6. The next sections will walk through how different valuation approaches view the stock, and then link those numbers back to the broader investment story.

Approach 1: Micron Technology Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting the cash it might generate in the future and then discounting those cash flows back to today using a required return.

For Micron Technology, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month Free Cash Flow is about US$9.6b. Analyst and extrapolated estimates, expressed in today’s money, show discounted Free Cash Flow projections ranging from roughly US$32.5b in 2026 to about US$5.2b in 2035, with a specific projected Free Cash Flow of US$24.9b for 2030.

Combining these projections, the model arrives at an estimated intrinsic value of US$268.39 per share. Compared with the recent share price of US$646.47, this implies the stock is around 140.9% above the DCF estimate, which points to a rich valuation under this framework.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Micron Technology may be overvalued by 140.9%. Discover 51 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Micron Technology Price vs Earnings (P/E)

For a profitable company, the P/E ratio is a straightforward way to see how much you are paying for each dollar of earnings. A higher P/E often reflects stronger growth expectations or a lower perceived risk, while a lower P/E can indicate more modest growth assumptions or higher perceived risk.

Micron Technology currently trades on a P/E of 30.24x. This is below the peer average of 70.86x and also below the broader Semiconductor industry average P/E of 59.42x, which suggests the stock trades on a lower earnings multiple than many comparable companies.

Simply Wall St’s Fair Ratio for Micron Technology is 65.61x. This is a proprietary estimate of what a reasonable P/E could be for the company, given factors such as its earnings profile, industry, profit margins, market cap and key risks. Because it is tailored to the company, the Fair Ratio can be more informative than a simple comparison with peers or the industry average alone.

Comparing the current P/E of 30.24x with the Fair Ratio of 65.61x indicates the stock is trading below this customised benchmark.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Micron Technology Narrative

Earlier it was mentioned that there is an even better way to understand valuation. This is where Narratives come in, giving you a simple story that links your view on Micron Technology’s business, its future revenue, earnings and margins, to a Fair Value that can be compared with today’s price.

On Simply Wall St’s Community page, Narratives are an easy tool that let you set assumptions, see the implied Fair Value and keep that view updated automatically when new information such as Micron Technology’s earnings or AI memory news is added.

For Micron Technology, one investor Narrative might build toward a Fair Value around US$124.20 based on more cautious assumptions about growth and margins. Another Narrative might point to a Fair Value near US$779.55 based on very optimistic expectations. Seeing those side by side helps you decide where your own view sits and whether the current price looks high or low against your chosen story.

For Micron Technology, however, we will make it really easy for you with previews of two leading Micron Technology Narratives:

Start by asking which story feels closer to how you see AI memory, data centers and the broader chip cycle playing out, then compare that with where the stock currently trades.

Fair value: US$779.55 per share

Implied valuation gap vs last close: about 17.1% below this narrative fair value

Revenue growth used in this narrative: 65.04% a year

• Assumes Micron captures a large share of high bandwidth memory and AI driven demand, supporting very strong revenue expansion and higher margins.
• Sees diversification across AI, industrial, automotive and edge markets as a way to smooth out some of the usual memory cycle swings.
• Uses a higher earnings base, wider margins and a lower future P/E to reach a fair value of about US$779.55, while flagging risks around data center dependence, NAND pricing and geopolitics.

Fair value: US$159.75 per share

Implied valuation gap vs last close: about 304.7% above this narrative fair value

Revenue growth used in this narrative: 26% a year

• Recognises AI and HBM as powerful demand drivers but pairs that with caution around memory cyclicality, fixed costs and the need for customers to regularly re set contract terms.
• Assumes revenue of about US$43b and earnings of US$11b in 2027, with margins improving from recent downturn levels and a future P/E of 21x.
• Arrives at a fair value of roughly US$160 per share, with detailed risks around competition, large capex plans, lean inventories and potential regulatory and intellectual property challenges.

These two narratives give you a structured way to test your own expectations against very different fair values. If your view on Micron's AI positioning, capital spending and memory cycles sits closer to the bullish case, the higher narrative fair value may resonate more. If you are more focused on cyclicality, supply risks and execution hurdles, the lower fair value might feel more realistic.

Once you have a sense of which narrative you lean toward, it becomes easier to decide whether the current share price of US$646.47 looks stretched, conservative or somewhere in between, and how much risk you are comfortable taking on relative to those assumptions.
