Republic Airways Holdings Inc. has completed its merger with Mesa Air Group, combining the two regional airlines into a single, larger operation. Under the agreement, Republic stockholders now own approximately 88% of the combined company's common stock, while Mesa stockholders will own at least 6%, and up to 12%, subject to final settlement of Mesa's pre-closing obligations. The merged company, trading under the ticker RJET on the NASDAQ Global Select Market, will operate the world's largest Embraer jet fleet with 310 E-Jets and support more than 1,300 daily departures. Republic Airways will continue partnerships with American Airlines, Delta Air Lines, and United Airlines, while Mesa Airlines will support United Airlines under a new 10-year agreement. Both airlines will maintain parallel operations as they work towards full integration.
