SOUTHDOWN INC

Southdown Inc. anchors its operations in the hydraulic cement segment of SIC 3241, supplying ready-mixed cement, clinker, and supplementary cementitious materials to infrastructure, commercial builders, and public utilities that rely on high-compression mixes for bridges, tunnels, and marine projects. The firm’s vertically integrated quarry, kiln, and distribution network lets it tailor orders for large contractors while striving to meet environmental mandates on dust, emissions, and quarry rehabilitation, yet exposure to volatile energy costs and tight water-use permitting underscores material regulatory risk. With its most recent disclosure in a Form 10-Q filed in November 1999, Southdown continues to navigate cyclical demand and compliance pressures while emphasizing reliable logistics and product quality; view live SEC filings on Earnings Feed.
