Positives
Pension plans hold more assets than they owe
“In total, the Company’s pension plans are overfunded (fair value of plan assets exceeds the projected benefit obligation) by $271 million at December 31, 2024.”
No variable-rate borrowings at year-end, limiting exposure to short-term rate changes

Internal controls over financial reporting were found effective
“management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2024”
Concerns
Severe weather disrupted operations during 2024
“Throughout 2024, unprecedented storms and flooding caused operational delays and challenges across much of the Company's geographic footprint.”
Interest rates remain high for rate-sensitive construction demand
“Demand in the nonresidential and residential construction markets, which combined accounted for 58% of the Company's 2024 aggregates shipments, is affected by interest rates.”
Energy price swings may not be fully passed on to customers
“A hypothetical 10% change in the Company’s energy prices in 2025 as compared with 2024, assuming constant volumes, would change 2025 energy expense by $32 million.”
New risks since the previous report
Tariffs and trade disputes could hurt the US economy
“trade disputes with one or more nations impacting the U.S. economy, including the impact of tariffs”
Cyberattacks are becoming more sophisticated, reportedly using artificial intelligence
“are reportedly using artificial intelligence to increase the virulence of attacks”
A large acquisition could require new stock and debt, and might still lower the credit rating
“It is possible a large strategic acquisition would require that we issue new equity and debt securities in order to maintain our investment-grade credit rating”
Biggest risks named
- Interest rate sensitivity of construction demand
- Uncertain timing and amount of public infrastructure funding
- Energy, fuel and raw material cost swings
- Severe weather and climate regulation
- Cement price and supply volatility

How these scores work
An AI model reads the management discussion, risk factors and legal sections of each report and records what they say, quoting the filing word for word. Fixed rules then turn those findings into a score from 0 to 100, where 60 means nothing notable either way. A score describes the report, not whether the stock is a good investment, and the AI may know how things turned out later, which can colour older scores. Read the methodology
