Answer:
The stock’s value per share is $10.42
Step-by-step explanation:
For: 
FCF1 = Expected cash flow of the firm 
 = $25 million 
WACC = 10% 
g = 4% 
Firm value = FCF1/(WACC - g) 
 = 25,000,000/(0.10 - 0.04) 
 = $416,666,666.67 
We know that there is no debt & preferred stock, so the firm value will be equal to Equity value :
Firm value = Equity value
 = $416,666,666.67
stock value per share = Equity Value/No. of share outstanding 
 = $416,666,666.67/40,000,000
 = $10.42 per share
Therefore, The stock’s value per share is $10.42
