A Discounted Cash Flow, or DCF, model estimates what a company might be worth today by projecting its future cash flows and discounting them back to a present value.

For Astellas Pharma, the model uses a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about ¥374.4b. Analysts provide forecasts out to 2030, with free cash flow for that year projected at ¥397.0b, and Simply Wall St extends the pattern further using its own extrapolation to build a 10 year path of cash flows in ¥.

When all those projected cash flows are discounted back and divided by the number of shares, the DCF model arrives at an estimated intrinsic value of about ¥5,034 per share.
