What Is Micron Actually Worth? I Ran the Bull and Bear Numbers

What price should you actually pay for Micron?

Here's my answer up front: I'm not buying Micron today. The gap between the bull-case and bear-case fair values is so wide that I can't reasonably estimate what this company earns ten years out. It's not a quality problem — it's a predictability problem.

I'm not saying this is a bad company. Quite the opposite. The issue is that justifying the price requires modeling a decade of cash flow, and that picture changes completely depending on whether the bull or bear case wins. So I ran both.

First, I checked the company itself

Market cap is about $1.2 trillion, and enterprise value is nearly identical. When those two are close, it tells me there's essentially no net debt — a very healthy balance sheet.

Free cash flow was $31.6 billion over the last year. But the five-year average is only $6.4 billion — a sign of enormous capital expenditure on fabs and equipment.

The profitability and growth are dazzling:

• Net margin: 29.7% over 10 years, 31.7% over 5, 56% in the last year
• Revenue growth: 21.5% over 10 years, 28% over 5, 70% over the last 3

One thing nags at me: return on invested capital is low. Even with cash flow and net income exploding, Micron has to shove a lot of money back into the business to produce that profit. I keep circling back to this.

Bull scenario: it's still cheap

I ran a 10-year analysis with optimistic inputs:

• Revenue growth: 20 / 25 / 30% a year
• Net margin: 35 / 45 / 55%
• Applied P/E in 10 years: 20 / 23 / 26x
• Required return: 9% (no margin of safety — I'm sizing the value itself)

Against the current price of roughly $1,044, the outputs are: a low of about $1,850, a midpoint near $3,900, and a high around $7,600. If those assumptions hold, you'd still earn 16–35% annually over the next decade from today's price.

Bear scenario: back to the cycle

Now I assumed Micron reverts to normal:

• Net margin: 7 / 12 / 17%
• Revenue growth: 20 / 25 / 30%
• P/E: 15 / 18 / 21x (still a high-quality business)
• Required return: 9%

Note this isn't even a true bear case — a 7% net margin still assumes revenue doubles over ten years. Yet the output flips dramatically: a low near $320, a midpoint around $670, and a high near $1,300.

The gap says everything

Same company, and the midpoint is $670 in one case and $3,900 in the other — nearly a 6x difference. That's exactly why I can't pull the trigger.

Warren Buffett puts it plainly: if he can't reasonably determine what a company will earn in ten years, he doesn't buy it. By that standard, Buffett passes on Micron here. So do I. I can't tell which scenario is more likely, and I'm not willing to buy while praying I'm right.

Analyst estimates capture the same dilemma. This year's ~$60 EPS is modeled to halve to ~$30 within four years, while revenue stays roughly flat. Flat revenue but falling earnings points to one thing: they don't believe gross margins hold. On why the price you pay matters more than the earnings themselves, I go deeper in why stock price matters more than earnings.

Where that leaves me

Micron is, without question, a high-quality business. But even the best company in the world becomes a bad investment if you overpay. That's the fifth tenet of my principle-driven investing: a great story turns into a bad investment at the wrong price. So I'm not rushing — I'll wait for a calmer moment. For a deeper valuation breakdown, I'd pair this with the Micron fair-price analysis.

FAQ

Q: Why is the gap between the bull and bear midpoints so large?

A: Almost all of it comes down to gross margin. The bull case assumes a 35–55% net margin; the bear case assumes 7–17%. Compound that over ten years and the difference blows out to roughly 6x.

Q: So is Micron a stock to avoid?

A: No. It only means that by my standard, right now, the predictability is too low, so I pass. For an investor convinced the cycle is truly broken, the bull scenario can be attractive. It ultimately comes down to your own conviction and required return.

Q: What does a 9% required return mean?

A: It's the minimum annual return I expect from this investment. The lower you set it, the more you justify paying up. If 9–10% is all you need, a low-cost ETF may be the more sensible choice.
