Bootstrapping earnings. Assume that Firm 1 issues additional shares to buy Firm 2 In scenario A, assume that the market applies the pre-merger P/E of Firm 1 to post-merger earnings. In Scenario B, assume that the market applies the weighted average P/E of the Firm 1 and Firm 2 to the post-merger company. (Weighted average P/E is calculated by multiplying the PE of each firm by its share of combined earnings and summing the two results.)
