| 1. | The pro forma combined earnings per share amounts were calculated by totaling the historical earnings of HomeStreet and Mechanics, adjusted for purchase accounting entries, and dividing the resulting amount by the average pro forma shares of HomeStreet and Mechanics, giving effect to the merger as if it had occurred as of the beginning of the period presented. The average pro forma shares of HomeStreet and Mechanics reflect historical basic and diluted shares of HomeStreet, plus historical basic and diluted average shares of Mechanics, as adjusted based on the fixed exchange ratio of 3,301.0920 shares of Class A common stock for each share of Mechanics voting common stock and a fixed exchange ratio of 330.1092 shares of Class B common stock for each share of Mechanics non-voting common stock. For the calculation of total estimated shares at the consummation of the merger, see Note 2. The transaction adjustment of 201.9 million is calculated as the hypothetical shares being issued to shareholders of Mechanics of 202.0 million less the existing shares of Mechanics held by shareholders of Mechanics of 64.2 thousand. Potential dilution from common equivalent shares is determined using the treasury stock method, reflecting the potential settlement of stock-based compensation awards resulting in the issuance of additional shares of common stock. |
