Houda Motors has just announced results that show that the FCF for the past year is $23 million. An experienced analyst believes that the growth rate of FCF for the next 10 years will be 25% per year and that after 10 years the growth rate will stabilize at 7% annually. Houda's WACC is 18% and it has 100 million shares outstanding. (Hint: You can find the FCFs for each year, but you can also value this using only formulas, you've got a fast-growing annuity and then a growing perpetuity as the two components of value here!)
