Ps = Share Price
PE = Price to Earnings Ratio = Ps / EPS
EPS = Earnings per Share = Earnings / No of Shares
So we have
EPS = Ps / PE
Earnings = EPS * No of Shares
Before the Merger:
For CIS -
Ps = $40
PE = 10
No. of Shares = 2,000,000
EPS = Ps / PE = $40 / 10 = $4.00
Earnings = EPS x No. of Shares = $4.00 x 2,000,000 = $8,000,000
For FF -
Ps = $20
PE = 8
No. of Shares = 1,000,000
EPS = Ps / PE = $20 / 8 = $2.50
Earnings = EPS x No. of Shares = $2.50 x 1,000,000 = $2,500,000
After the Merger -
Combined Earnings = $8,000,000 + $2,500,000 = $10,500,000
