Key Financial Metrics (2025)

Material Changes vs. Prior Period

• Revenue Growth: Revenues increased 8.6% to $6.15 billion, driven by higher organic shipments, improved aggregates pricing (up 6.9% year-over-year), and contributions from acquisitions.
• Profitability Decline: Earnings from continuing operations dropped significantly from $1.82 billion in 2024 to $990 million in 2025. The 2024 results were anomalously high due to a $1.3 billion pretax gain on the divestiture of the South Texas cement business. Excluding this one-time gain, underlying operating performance remained robust.
• Segment Performance:
  • Building Materials: Aggregates gross profit increased to $1.68 billion (34% margin). Other Building Materials gross profit declined 18% due to lower asphalt pricing and the divestiture of California paving operations.
  • Specialties: Revenues surged 38% to $441 million and gross profit rose 29% to $137 million, driven by pricing gains and the July 2025 acquisition of Premier Magnesia.
• Divestitures and Acquisitions:
  • Divestiture: In August 2025, the company entered an agreement to exchange its Midlothian cement plant and Texas ready-mixed concrete assets for aggregates facilities and cash from Quikrete Holdings. These assets are now classified as "held for sale" and reported as discontinued operations.
  • Acquisitions: Completed the acquisition of Premier Magnesia (July 2025) and several bolt-on aggregates operations in 2024 and 2025.

Guidance, Outlook, and Risks

Management Commentary: Management expects 2026 demand in nonresidential segments (data centers, warehousing) to remain strong. However, the residential construction market faces headwinds from high mortgage rates, with a recovery expected only when rates decline. The company continues to focus on its "SOAR" strategic plan, prioritizing aggregates-led acquisitions and organic capital investment while maintaining a leverage ratio target of 2.0x to 2.5x.

Key Risks and Contingencies:

• Weather and Climate: Operations are highly sensitive to weather patterns. Hurricanes, flooding, and extreme temperatures can disrupt production and shipments, particularly in coastal markets.
• Interest Rates: Sustained high interest rates may dampen residential and nonresidential construction demand and increase financing costs.
• Regulatory Environment: Environmental regulations regarding greenhouse gas emissions (GHG) and land use permitting pose ongoing compliance costs and potential operational constraints.
• Transaction Risks: The pending Quikrete asset exchange is subject to closing conditions and integration risks.

Investor Verification Checklist

• Discontinued Operations: Verify the impact of reclassifying the cement and Texas ready-mixed concrete operations as discontinued operations on future comparability.
• Quikrete Transaction: Monitor the closing status and terms of the asset exchange with Quikrete Holdings, including the specific aggregates facilities to be acquired.
• Residential Construction Trends: Track single-family housing starts and mortgage rates, as residential construction accounted for 22% of aggregates shipments in 2025.
• Debt Maturities: Review the debt schedule, noting $792 million in maturities due in 2027 and the company's ability to refinance or repay without impacting liquidity.
• Acquisition Integration: Assess the integration progress and financial contribution of the Premier Magnesia acquisition to the Specialties segment.
