A worked DCF of 3M

Built from the company's annual filing for the fiscal year ended 31 December 2025, with market inputs as of 15 September 2026. Every figure below carries a tag saying where it came from, and every result is computed by the same engine as the VALUATIO terminal. A worked example of the method, not a view on the stock.

What went in

Every input the model uses is here. The tag beside each one says where it came from, so you can tell a number 3M filed from one this page assumed.

Five years of free cash flow

Revenue grows along the path above; margins, capital spending and tax stay at the filed year's proportions. Free cash flow is what is left for every provider of capital, and each year is discounted back at the WACC below, from the middle of the year, because cash arrives through it rather than on the last day.

The discount rate

The weighted average cost of capital blends what shareholders and lenders expect to earn, weighted by how much of the company each finances.

Cost of equity: 4.97% + 0.95 × 5.00%9.72%
After-tax cost of debt: 5.71% × (1 − 23.8%)4.35%
WACC: 75% equity, 25% debt8.38%

From cash flow to one value per share

After year five the model assumes free cash flow grows at 2.25% a year for ever: the Gordon growth terminal value, which is year-five free cash flow of $4,319m grown one year, divided by WACC less growth.

Present value of five years of free cash flow$16,901m
Terminal value at the end of year five$72,065m
Present value of the terminal value$50,176m
Enterprise value$67,076m
Less net debt($7,367)m
Equity value$59,709m
Divided by shares outstanding515.7m
Value per share$115.78

The terminal value is 75% of enterprise value, so most of this answer rests on the years after the forecast. That is normal for a DCF, and it is why the next table matters.

How much the answer depends on two inputs

Value per share across a range of discount rates and terminal growth rates. The centre is the model above. Move the discount rate one point either way and the value runs from $98.04 to $140.44 a share: small inputs, large answers.

What this model does not know

  • The growth path is an estimate, not anyone's forecast: it starts at last year's revenue growth, 1.5%, and tapers to 3% by year five.
  • The equity risk premium, the debt share of the capital structure, working capital and terminal growth are house defaults, the same documented assumptions the terminal starts from. They are tagged DEF above.
  • Capital spending stays at 3.6% of revenue for all five years. A company in a heavy investment cycle looks worth less here than it will if that spending falls.
  • Net debt is borrowings less cash, as filed. Operating leases are left out.
  • No share price appears on this page, on purpose. It teaches how a DCF is built; it does not say whether the stock is cheap or dear.

Now change it

The terminal opens this exact model with 3M's filing already loaded. Change the growth path, the margin or the discount rate, and every figure on this page moves with it. Market inputs there are live, so they may have moved since 15 September 2026.
