CEMEX, S.A.B. de C.V.

Cement, ready-mix, aggregates and urbanization solutions

Cemex reports 2025 consolidated net sales of $16.132 billion and EBITDA of about $3.1 billion. Its public materials describe cement, ready-mix, aggregates and related services. Current public sources support the circular-kiln direction, but not a site-specific acceptance specification, permit boundary, calorific value, moisture range or offtake economics.

$16.132B FY2025 revenue

$3.1B FY2025 EBITDA, company-reported

31% U.S. share of 2025 external revenue

Evidence Site lane must be qualified plant by plant

• Limestone, clay, gypsum and other cement raw materials
• Fuels, including potential alternative fuels where permitted
• Aggregates, water, admixtures and supplementary cementitious materials

Outputs and residuals to resolve

• Cement, ready-mix concrete, aggregates and urbanization solutions
• Kiln dust, clinker and process byproducts
• Emissions, ash, dust and residual streams require plant-level review

First decision: Pick one kiln or aggregate site, then qualify one input against its permit, calorific or mineral specification, emissions controls and delivered logistics cost.

Cemex, S.A.B. de C.V. controls the public operating group and reports by geographic segment.

U.S. weight

The U.S. represented 31% of 2025 external revenues and 45% of total assets in the 20-F.

Physical system

Quarries and raw-material preparation feed cement plants; cement flows into ready-mix and construction applications.

Evidence boundary

Alternative fuels and circular inputs are a credible lane, but the public record does not establish an open receiving site or contracted supply.

Decision boundary

The public record supports one bounded next move: Pick one kiln or aggregate site, then qualify one input against its permit, calorific or mineral specification, emissions controls and delivered logistics cost. It does not establish a buyer, commercial approval or supply agreement.

This is a public screening map. It separates company-disclosed flows from open qualification work. It does not convert a destination into a buyer or an announced ambition into operating capacity.

Qualify one kiln-ready alternative fuel

Alternative fuel is a physical operating decision, not a corporate target. The lane lives or dies on calorific value, moisture, contaminants, permit and delivery cost.

Next evidence: Name a kiln, obtain acceptance criteria and run a controlled trial plan with emissions monitoring.

Match secondary minerals to a cement blend

Industrial byproducts can matter when chemistry and consistency are proven.

Next evidence: Compare chemistry, grind, moisture, dosage and concrete performance against the current blend.

Treat U.S. scale as a logistics map

The U.S. is a large operating and asset base, but geography changes the delivered economics.

Next evidence: Map source radius, truck or rail route, storage, preprocessing and site-level gate fees.

Source hierarchy: filings and company disclosures first. The brief states what those sources support and leaves the unresolved plant, grade, permit, buyer and mass-balance questions explicit.

The next useful working session starts with: Pick one kiln or aggregate site, then qualify one input against its permit, calorific or mineral specification, emissions controls and delivered logistics cost.
