Granite's year-end 2025 S-K 1300 portfolio comprised 116 US aggregate properties over 31,797 acres: 86 in production, 15 in development and 15 in exploration. The portfolio contained 697.7 million tons of measured, indicated and inferred resources and 1,383.2 million tons of proven and probable reserves, and produced 22.8 million tons in 2025. Granite states that no individual mining operation is material. The April 2026 Kenny Seng acquisition subsequently added a Utah hard-rock quarry, a potential sand-and-gravel pit and approximately 45 million tons of separately disclosed reserves and measured and inferred resources.
