COMPANY OVERVIEW

Our Challenges

• Carbon capture and other innovations are yet to be proven; today, there is no commercially viable technology to
meaningfully reduce emissions in cement production
• We must comply with ASTM International (ASTM), the Texas Department of Transportation (TXDOT) and our customer
specifications, which differ from cement and lime requirements in other regions
• Alternative fuel and additives are regulated differently in the U.S. than in other countries

• The U.S. EPA requires certain calculation methods regarding alternative fuels that are different from methods
employed by other countries, making same-on-same comparisons of GHG difficult

Our Intentions

• Make promises we can keep and explain how we intend to do so
• Operate our business in a responsible manner from a long-term financial perspective
• Stay close to developing technology (e.g. Fortera, amine scrubbing, cryogenic treatment, etc.) and use our healthy
balance sheet to implement technology quickly when it becomes viable in our lone remaining heritage cement plant
• Continue to work with Caterpillar, Komatsu, John Deere and other partners to improve emissions in our aggregates
business, and deploy new technology as it becomes available
• Comply with state and federal disclosure rules and other regulatory developments
• Continue to gather data for our Scope 3 emissions, including trucking and railroads
• Continue the process of setting and verifying reduction targets under the SBTi framework
• Continue to speak with, listen to, and respond to our shareholders
