Cobb County taxpayers will continue to benefit from the lowest possible borrowing costs on bonds funding roads, parks and infrastructure after all three major credit rating agencies reaffirmed the county's AAA status for the 29th consecutive year.

The county announced the ratings on Wednesday, Aug. 5, confirming that Moody's Investors Service, S&P Global Ratings and Fitch Ratings each awarded their highest marks. Only about 2 percent of U.S. counties hold triple-AAA ratings from all three agencies simultaneously. That streak is rare.

The distinction matters at the kitchen table. AAA-rated governments borrow at the lowest available interest rates, which translates to millions in savings on bond-funded capital projects like the stormwater, water and sewer work included in the $1.4 billion FY2027 budget the Board of Commissioners approved July 28.

The county said on its official social media account that the ratings reflect "responsible financial management and long-term stability."

In its Aug. 19, 2025 rating report, S&P Global cited the county's robust economy, consistent financial performance, sizable reserves, proactive management practices and manageable debt. The agency noted that economic expansion was being driven by business investments, new construction and sprawl from Atlanta, and projected the county's finances would remain healthy due to growing revenues and conservative management.

Board of Commissioners Chairwoman Lisa Cupid said in August 2025, when the county secured its 28th consecutive AAA rating, that the recognition "should give our residents confidence that the county is a good steward of their tax dollars as we grow and meet diverse expectations."

Commissioners held millage rates flat for FY2027 at 8.46 mills for the General Fund and 2.97 mills for the Fire Fund, even as the overall budget grew by $84 million, or about 6 percent, over the prior year. The budget passed on a 3-2 party-line vote, with Democrats in favor and Republicans opposed.
