Management Comments

• "We are pleased to be at the finish line for closing of the merger of Mesa with Republic."

Industry Context

This announcement reflects a significant consolidation event within the regional airline sector, where smaller carriers often operate under capacity purchase agreements with major airlines. The merger of Mesa and Republic, two regional operators, aims to create a larger, more financially stable entity, potentially leveraging economies of scale and optimizing fleet utilization. The focus on E-175 operations and the new 10-year agreement with United Airlines highlight the ongoing reliance on major airline partnerships and the strategic shift towards more efficient aircraft types in the regional market. The asset sales and debt reduction by Mesa also indicate a broader industry trend of rationalizing older, less efficient fleets.

Comparison to Industry Standards

• Mesa's 100.00% controllable completion factor, 81.8% on-time arrival rate, and 36.1 United Airlines Net Promoter Score were the highest among United regional operators for the quarter, indicating strong operational performance relative to its direct peers within the United Express network.
• The significant debt reduction by Mesa, repaying over two-thirds of its debt principal over the past year, positions it more favorably compared to regional carriers that may be struggling with high leverage, especially in a capital-intensive industry.
• Republic's strong adjusted EBITDA of $227.4 million and net income of $71.2 million for the nine months ended September 30, 2025, demonstrate robust financial health, which is a positive indicator for the combined entity, potentially setting a higher benchmark for profitability and operational efficiency compared to other regional airlines.
• The 15-for-1 reverse stock split is a common corporate action often undertaken by companies with low stock prices to meet exchange listing requirements or make shares more attractive to institutional investors, similar to actions seen in other struggling or consolidating companies in various sectors.
