Moody’s adjusts Coca-Cola FEMSA’s rating

Mexico City, Mexico, May 22, 2026 – Coca-Cola FEMSA, S.A.B. de C.V. (BMV: KOFUBL; NYSE: KOF) (“KOF” or the “Company”) announces that Moody’s Ratings has adjusted KOF’s rating to Baa1 from A3, reflecting the downgrade of the Government of Mexico to Baa3 from Baa2. In addition, it adjusted KOF’s outlook from Stable to Negative, in line with the change to Mexico’s outlook.

Although, Moody’s highlights that KOF is rated two notches above the sovereign because of its strong credit metrics, ample liquidity, limited reliance on the local banking system, and cash generation outside Mexico.
