Zero-growth floor

$148

Central IV

$254

Optimistic top

$301

Micron Technology Inc (MU): A conservative value band $148–$301 / sh (zero-growth floor to growth-capped optimistic top); central read about $254. Today’s price sits above that band (price $879 as of 2026-10-16).

The middle figure is the main read. The right end is the optimistic case under the same conservative caps — not an absolute ceiling.

  • Capex doubled in two years, so maintenance is hard to pin down — read the band conservatively.

Method & numbers

Buybacks over the years shown roughly only offset stock-based-compensation dilution — read them as maintaining the share count, not a net return of capital.

Model cautions

  • Capex doubled within two years: maintenance is floored then capped at D&A (OE may look optimistic); Greenwald growth value is closed — growth credit stays in the owner-earnings DCF only.
  • Owner-earnings yield diverges sharply from the 10-year Treasury (over 300 bps).
  • Growth nearly matches the discount rate — the estimate is sensitive to assumptions.

A conservative intrinsic-value band (zero-growth floor to growth-capped DCF) plus a tangible asset floor — not investment advice, not a buy/sell signal, and not a price target.

Owner-earnings DCF $161.92 – $300.66 · Greenwald zero-growth $253.35 · zero-growth base $253.35 · reproduction $131.10

Graham earnings-power value (normalized NOPAT)$212.57 – $253.35 / sh

Normalized NOPAT = average operating margin over the years shown × latest-year revenue × (1 − normalized tax); then + D&A − maintenance capex (write A). Unlevered (pre-interest, attributable to all capital). Capitalized at the 9–11% rate band (read as a WACC proxy). Enterprise → equity bridge applied: + cash − total debt.

Years: 2026, 2025, 2024, 2023, 2022

v1 simplifications: Maintenance capex (degraded) deducted in full cash (write A): EPV = (NOPAT + D&A − maintenance capex) / WACC; no tax shield on the capex term. Only one maintenance-capex method available; estimate is degraded. Capex doubled within two years (AI-hog rule): flagged; the spike is treated as growth, not maintenance — owner earnings carry extra uncertainty. Share-based compensation is left as a real expense (not added back).

Buffett owner-earnings value$147.98 – $180.86 / sh

Owner earnings = average net income + average D&A − maintenance capex (zero-growth floor; no ΔNWC). Levered (starts from net income, already after interest — an equity-holder stream). Capitalized at the 9–11% rate band (read as a cost-of-equity proxy). No enterprise→equity bridge: the capitalized result is already equity value (subtracting debt would double-count interest).

Years: 2026, 2025, 2024, 2023, 2022

v1 simplifications: Owner earnings = net income + D&A − maintenance capex (degraded); the working-capital change is excluded (maintenance ΔNWC ≈ 0; growth ΔNWC is carried in growth value, not double-counted). Only one maintenance-capex method available; estimate is degraded. Capex doubled within two years (AI-hog rule): flagged; the spike is treated as growth, not maintenance — owner earnings carry extra uncertainty. One-time items are not separately normalized (multi-year averaging smooths them partially). Share-based compensation is left as a real expense (not added back); see the SBC/OE disclosure. Capitalized at the 9–11% band as a cost-of-equity proxy; no leverage premium applied (net cash or debt within the no-charge range).

Reproduction value = tangible net assets $137.23B + capitalized R&D $12.62B（FY 2026, 2025, 2024, 2023, 2022） = $131.10 / sh. Reproduction value = tangible net assets (equity − goodwill − intangibles) + capitalized R&D (5y straight-line), ÷ diluted shares.

Moat reading: Franchise test compares earnings power (EPV) against reproduction value on both AV_conservative (tangible + capitalized R&D) and AV_reproduction (conservative + acquired-reset proxy). Both must clear the franchise multiple for a moat signal; near it, a commodity; below it, value destruction. A directional reading, not a verdict.

Assumes a narrow moat · competitive-advantage period ≈ 10 years.

Growth value gated to zero — capex doubled within two years (AI-hog); growth credit stays in the owner-earnings DCF only.

Window FY 2026, 2025, 2024, 2023, 2022 · discount band 9%–11% · normalized tax 14% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.

Owner-earnings DCF: growth g₁ 7% · OE FY 2026, 2025, 2024, 2023, 2022 · Discount band: 9.60%–12.00% (DGS10 +4.5% to a 12% strict end, as of 2026-10-15). No enterprise→equity bridge: owner earnings already flow to shareholders (post-interest), so no net cash is added and no debt subtracted — matching the engine owner-earnings lamp.

What the price is betting

Today's price pencils in about over 30.0% (outside the usual range) a year in owner-earnings for the next few years. Revenue actually grew 29.0% a year.

The market wants it well ahead of its own track record.

Roughly, the price needs its historical revenue growth to run about 9 more years to hold up.

Even when the value band is low-confidence: use this to see what the price assumes — not as a cheapness confirmation.
