Positives

• Extension of the loan maturity date provides additional financial flexibility.
• Zero percent interest rate for 90 days reduces immediate financing costs.
• Waiver of certain loan restrictions and liquidity tests eases compliance burdens.
• Potential $12.3 million reduction in loan principal upon full repayment is a significant benefit.

Negatives

• Mesa Airlines had to deposit cash and pledge an aircraft engine as additional collateral for the amended loan.
• The $12.3 million principal reduction is conditional on full payment of obligations by the maturity date, not guaranteed.
• Pre-Merger Mesa Shareholders' ownership in the combined company (6% to 12%) is variable and dependent on the Net Debt Amount and the value of Escrow Shares, which are first used to compensate United Airlines.
• The value of Escrow Shares and the NOL credit are sensitive to the combined company's share price post-merger and Mesa's share price at closing, introducing uncertainty for pre-merger shareholders.

• Effects relating to the announcement or consummation of the transaction on the market price of Mesa Common Stock.
• Mesa's compliance with Nasdaq listing requirements.

Future Outlook

Management anticipates continued strong combined financial performance in the second half of the calendar year. The combined company is expected to achieve twelve-month run-rate annual revenue between $1.8 billion and $2.0 billion.

Management Comments

• "We are pleased Mesa would support day-one benefits for the combined company, and we continue to work closely with the Republic executive team to position our airline for a successful Merger closing and integration with Republic." Jonathan Ornstein, CEO of Mesa.

Industry Context

The regional airline sector continues to consolidate, and this merger between Mesa Air Group and Republic Airways Holdings Inc. represents a significant move to create a larger, more financially robust entity. The new, enhanced 10-year capacity purchase agreement with United Airlines for Mesa's E-175 fleet underscores the ongoing reliance of major carriers on regional partners and provides a stable revenue stream for the combined entity, a critical factor in the often-volatile airline industry. The focus on operational efficiency and fleet optimization, as evidenced by the E-175 agreement, aligns with broader industry trends towards cost management and strategic partnerships.

Comparison to Industry Standards

• The combined company's estimated run-rate annual revenue of $1.8 billion to $2.0 billion positions it as a leading regional airline, comparable in scale to other significant regional players like SkyWest, Inc. (SKYW) or Endeavor Air (a Delta subsidiary), though direct public comparisons are limited due to varying business models and ownership structures.
• Republic's adjusted EBITDA of $169 million for H1 2025 demonstrates strong operational performance, which appears robust within the regional airline segment, especially when compared to Mesa's $14 million adjusted EBITDA for the same period, highlighting Republic's stronger financial health prior to the merger.
• The new 10-year capacity purchase agreement with United Airlines for 60 E-175 aircraft is a long-term commitment, providing revenue stability that is a benchmark for successful regional airline operations, similar to long-term agreements held by other regional carriers with major airlines like American, Delta, or Alaska.

Stakeholder Impact

• Shareholders (Pre-Merger Mesa): Will own 6% to 12% of the combined company, with the exact percentage and value dependent on Escrow Shares and Net Debt Amount, which are influenced by the combined company's share price post-merger and Mesa's share price at closing.
• Shareholders (Combined Company): Expected to benefit from a larger, more financially robust entity with strong revenue and EBITDA projections, and a stable long-term capacity purchase agreement with United Airlines.
• Employees: The merger will likely lead to integration efforts, which could impact roles and organizational structure, though the filing does not provide specifics.
• Customers (United Airlines): Will continue to benefit from Mesa's regional service under a new, enhanced 10-year capacity purchase agreement.
• Creditors (Jefferies Capital Services, LLC): Received additional collateral (cash and aircraft engine) and an extended maturity date, but also agreed to a temporary 0% interest rate and potential principal reduction.

Next Steps

• Mesa's special meeting of stockholders on November 17, 2025, to vote on merger proposals.
• Tentative closing of the merger with Republic Airways Holdings Inc. on November 19, 2025.
• Mesa has the right to extend the loan maturity date by 30 days by providing notice to the Administrative Agent by November 27, 2025.
• Full payment of obligations under the Loan Agreement on the Maturity Date to realize the $12.3 million principal reduction.
• Integration of Mesa and Republic Airways post-merger closing.
• Determination of the Net Debt Amount and allocation of Escrow Shares, impacting pre-merger Mesa shareholders.

Key Dates

Recommendation

The filing details significant positive developments that are highly likely to drive shareholder value. The favorable amendment to the Treasury loan, including an extended maturity and a temporary 0% interest rate, alleviates immediate financial pressure. More importantly, the merger with Republic Airways is on track, creating a larger, more diversified regional airline with robust combined financial projections ($1.8B-$2.0B run-rate revenue, $183M H1 2025 Adjusted EBITDA). The new 10-year capacity purchase agreement with United Airlines provides long-term revenue stability, a critical de-risking factor in the airline industry. While the exact equity split for pre-merger Mesa shareholders is variable, the overall strategic benefits and improved financial outlook of the combined entity present a compelling investment opportunity. The potential for Mesa's NOLs to be credited against the Net Debt Amount further enhances the value proposition for existing shareholders.
