KBRA Assigns AAA Rating to Metropolitan Transit Authority of Harris County, TX Sales Tax Contractual Obligations Series 2026; Affirms Rating for Outstanding Bonds; Outlook Stable
6 Apr 2026 | New York
KBRA assigns a long-term AAA rating to Metropolitan Transit Authority of Harris County, Texas (the Authority) Sales and Use Tax Contractual Obligations, Series 2026. Concurrently, KBRA assigns the AAA rating to the Authority's outstanding Contractual Obligations and affirms the AAA long-term rating on the Authority's outstanding Sales Tax Bonds. The Outlook is Stable.
Sales and Use Tax Contractual obligations are secured on parity by a gross lien pledge of 75% of receipts from a voter-authorized 1% sales and use tax (sales tax) collected on taxable transactions within the County service area. The remaining 25% of receipts are dedicated by the County electorate to general mobility purposes through September 2040. The Texas Comptroller acts as the collection agent for the sales and use tax, which is levied against the same tangible personal property and certain taxable services as the State sales and use tax.
Proceeds of the Sales and Use Tax Contractual Obligations Series 2026 (Series 2026) will finance the cost of acquiring or reimbursing the purchase of personal property including, but not limited to, light rail vehicles, bus rapid transit articulated buses, clean diesel and compressed natural gas transit and commuter buses, farebox equipment, and pay costs of issuance.
Key Credit Considerations
Credit Positives
- Economically vibrant service area that represents a substantial proportion of the nation’s fifth largest metropolitan area.
- Pledged sales tax revenues provide ample coverage of annual debt service and demonstrate consistent growth despite exposure to oil and gas industry cycles.
- ABT requirement of 2.0x MADS coverage limits overleveraging of pledged sales taxes.
Credit Challenges
- Bonds are secured by sales taxes, collections of which can be adversely affected by economic factors.
- Planned debt issuance may lower coverage and reduce residual sales tax revenues available for operations.
Rating Sensitivities
For Upgrade:
- Not applicable.
For Downgrade:
- Failure to manage capital plan execution risks, leading to a substantial increase in debt above what is expected.
- While unlikely, a significant and prolonged secular economic downturn resulting in a sharp reduction of pledged sales tax revenue collections and material reduction in debt service coverage and operational flexibility.
