Key Credit Considerations

The rating actions reflect the following key credit considerations:

Credit Positives

• Established enplaned passenger growth trend, supported by a vibrant, diverse underlying economy.
• Strong airline commitment to market, with the new, relatively long dated AULA (FY 2035) ensuring a minimum 1.4x debt service coverage through supplemental charges.
• Well-managed financial operations, characterized by solid debt service coverage and substantial liquidity.

Credit Challenges

• Capital intensive nature of operations, exacerbated by rapid enplanement growth over an extended period.
• Increasingly constrained, though still sufficient, financial flexibility given expected, significant increase in debt.
• Construction, implementation and execution risks associated with a transformative, multi-year capital plan.

Rating Sensitivities

For Upgrade

• While not anticipated over the near-term, completion of the AEDP within the expected timeline and budget, accompanied by continuing strong enplanement growth, and related non-airline revenue, leading to significant moderation in the Airport’s pro-forma debt burden.

For Downgrade

• Failure to achieve projected enplanement growth resulting in weaker financial performance and higher leverage and airline costs than what it is currently anticipated.
• Absent a commensurate rise in resources available for repayment, the issuance of additional debt beyond what is currently contemplated.
