S&P lifts Houston airport system ratings

Increased activity at Houston airports led S&P Global Ratings to boost certain ratings by a notch as the city eyes debt issuance for the three-airport system in the first quarter of 2023.

The rating agency raised the system’s subordinate-lien general airport revenue bond rating to A-plus from A with a stable outlook affecting about $2.2 billion of debt outstanding as of the end of June.

“The upgrade reflects a passenger recovery resulting in an improved enterprise risk profile to
extremely strong and an unchanged strong financial risk profile,” S&P analyst Ken Biddison said in a statement.

Enplanements at Houston airports are trending higher with September 2022 levels coming in at 103% of pre-pandemic September 2019 levels, according to S&P Global Ratings.

Houston Airport System

Officials at the airport system, which is owned and operated by the city of Houston and consists of George Bush Intercontinental Airport, William P. Hobby Airport, and Ellington Airport, were not available to comment on the rating action. The city anticipates selling airport bonds in February, according to a source familiar with the matter.

In a report, S&P noted the system’s enplanements are trending higher, with September 2022 coming in at 103% of pre-pandemic September 2019 levels. 

“Because of (the system’s) recovery in air travel demand and return to business-as-usual rate-setting flexibility, we expect the airport will maintain financial metrics consistent with a strong financial risk profile despite an approximately $2.3 billion capital improvement program from fiscal years 2023 through 2027 that the airport is evaluating through a new feasibility study,” the report said.

S&P also upgraded to A from BBB-plus the rating on airport system special facilities taxable revenue bonds with a stable outlook. The bonds, which financed a rental car facility at George Bush Airport, are secured by a $4-per-day rental car customer facility charge.

“The upgrade reflects recovering rental car activity resulting in an improved enterprise risk profile to strong and an unchanged strong financial risk profile,” Biddison said. 

In September, Fitch Ratings upgraded the system’s subordinate-lien revenue bond rating to A–plus from A, citing “the system’s sustained robust financial performance and future leverage expectations, supported by the strong regional monopoly characteristics.”
