A two-stage DCF adds explicit projected years and a terminal value.

Explicit years plus terminal value
A two-stage DCF adds the present value of a few explicit projected cash flows to the present value of a terminal value for everything after that.
V0=PVexplicit+PVterminal
DCF value under assumptions
The first 3 projected years have present value $248.69. The terminal value is a $100.00 per year perpetuity valued at $1,000.00 at the end of year 3; its present value today is $751.31. The DCF value under these assumptions is $1,000.00.
This reconciles exactly to valuing the whole level perpetuity directly, which is also $1,000.00 under the same cash-flow and discount-rate assumptions.
