Contra Costa bonds Fitch rating

Highlights

Fitch assigned a 'AAA' rating to Contra Costa Transportation Authority's $97,405,000 series 2026A refunding bonds and affirmed the rating on outstanding bonds.
The bonds will be sold competitively in the week of Nov. 16, 2026, with proceeds refunding series 2017A and 2018B for debt service savings, and no maturity extension.
Coverage is supported by ample stressed revenue assumptions and no future debt plans, with the bonds backed by Measure J's half-cent sales tax expiring March 31, 2034.

Refunding plan and rating rationale

As reported by Fitch Ratings, the agency assigned a 'AAA' rating to Contra Costa Transportation Authority's $97,405,000 sales tax revenue refunding bonds, series 2026A, and affirmed the same rating on its outstanding sales tax revenue and revenue refunding bonds.

The bonds are expected to be sold through a competitive sale in the week of Nov. 16, 2026. Proceeds are set to refund part of the authority's series 2017A and 2018B bonds to generate debt service savings, with no extension of final maturity.

Fitch said the rating reflects its U.S. public finance dedicated tax and revenue bond criteria, including an 'aa' revenue risk assessment tied to broad-based pledged revenues. The agency said those revenues show moderate sensitivity to cyclical stress, while long-term growth prospects remain slightly below U.S. GDP, supported by strong regional economic growth.

Coverage strength and county tax backing

Fitch said the 'aaa' resilience assessment is supported by ample maximum annual debt service coverage under its stressed revenue assumptions and by the issuer's lack of plans for future debt. The agency said a downgrade could follow if stressed coverage erodes substantially toward 2.5x or if pledged revenue growth slows significantly, while an upgrade is not possible because the rating is already at 'AAA'.

The bonds are backed by revenue from the half-cent retail transactions and use tax authorized under the voter-approved Measure J ordinance and levied across Contra Costa County. That sales tax is scheduled to expire on March 31, 2034, after the bonds' final maturity on March 1, 2034.

Our earlier article on Fitch’s rating of Hainan Rubber’s proposed subordinated perpetual securities explained why the notes were rated below the issuer, reflecting their subordinated status and the issuer’s ability to defer coupons. We also outlined Fitch’s view of Hainan Rubber’s leverage and liquidity profile, including the role of state-linked support in sustaining market access despite elevated debt metrics.
