Mesa Air Group, the parent company of Arizona-based Mesa Airlines, will soon ask its shareholders to vote on its planned merger with Republic Airways.
In a third-quarter earnings statement released Wednesday, Mesa said it will file a definitive proxy statement and prospectus with the U.S. Securities and Exchange Commission. The documents will then be mailed to shareholders for a vote.
In June, Mesa and Republic cleared the mandatory waiting period for mergers under federal antitrust law, and the SEC declared the partners’ registration statement – a preliminary version of the proxy statement and prospectus – “effective,” meaning the deal can move forward.
Republic’s shareholders have already approved the merger.
Mesa reported third-quarter operating revenue of $92.8 million and net income of $20.9 million, up from a loss of $19.9 million in the corresponding quarter of 2024.
Mesa Chairman and CEO Jonathan Ornstein said that, given the two airlines’ recent financial performance, he expects the combined company would have 12-month run-rate annual revenue in the range of $1.8 billion to $2.0 billion.
Republic and Mesa first announced plans to merge in April. The combined company will keep the Republic name, and 88% of the business will be owned by Republic shareholders. Mesa shareholders will own a minimum of 6% and up to 12% depending upon Mesa achieving certain pre-closing criteria.
The carriers will continue operating flights for their current partners. Republic has service agreements with United, Delta, and American, while Mesa works only with United, flying as United Express.
The merger is expected to close in the third or fourth quarter of 2025.
All-Embraer Fleet
Mesa also announced that it is flying only Embraer E175 aircraft as part of its transition to a single-type fleet. It is in the process of selling off its out-of-service Bombardier CRJ-900s.
Officials said the move to an all-Embraer fleet will simplify Mesa’s operations and reduce costs in the long term.
The airline currently operates 60 E175s, with 254 daily departures.
