Answer:
If the current earnings per share of TargetCo. are $2.10, and the times earnings multiple is 12, the relative valuation should result in a $2.10 x 12 = $25.20 per stock. This means that the premium per stock = $25.20 - $21 = $4.20, and the total premium paid for all the 1.9 million shares = $7.98 million.
