⁽¹⁾	Due to a loss for the three months ended June 30, 2018, zero incremental shares are included because the effect would be antidilutive.

Basic income per common share is computed by dividing net income attributable to Mesa Air Group by the weighted average number of common shares outstanding during the period.

The number of incremental shares from the assumed issuance of shares relating to restricted stock and exercise of warrants is calculated by applying the treasury stock method. Share-based awards and warrants whose impact is considered to be anti-dilutive under the treasury stock method were excluded from the diluted net income or loss per share calculation. In loss periods, these incremental shares are excluded from the calculation of diluted loss per share, as the inclusion of unvested restricted stock and warrants would have an anti-dilutive effect. Anti-dilutive shares relating to restricted stock and exercise of warrants of 523,343 and 11,056,295, respectively, were excluded from the calculation of diluted loss per share for the three months ended June 30, 2018.
