Environmental Stewardship

We have made the following enhancements to our Sustainability activities in recent years:

• In our 2022 Sustainability Report, issued in April 2023, we expanded our roadmap for achieving our stated Scope 1
greenhouse gas (GHG) emissions targets for 2030, increased disclosure about Board of Directors’ governance of our
sustainability efforts, added a Task Force on Climate-related Financial Disclosures (TCFD) alignment table, and adopted a Net
Zero by 2050 ambition for our Scope 1 emissions across all our product lines. We also reiterated our previously released
targets for Scope 2 emissions (including a Net Zero 2050 target).
• We continued our work during 2023 to reach our 2030 goals for Scope 1 reductions through
efficiency projects, equipment optimization and the rollout of Portland Limestone Cement (PLC)
or Type 1L in Texas.
• We purchased a second tranche of renewable energy credits (RECs) in 2023 to offset Scope 2
emissions.
• In 2023, we completed the construction of three wind turbines at our Woodville, Ohio plant.
This will allow us to provide a significant portion of the Woodville Quarry’s electrical energy
needs.

• Our participation in the recycled aggregates market continued following the acquisitions of recycling assets in Texas, California
and Minnesota in recent years. We processed and shipped approximately five million tons of concrete and asphalt generated
from various construction and demolition projects in 2023.
• During 2023, our Chair and CEO, joined by other senior executives, engaged with an increased number of investors and
others relating to our Sustainability story through proactive shareholder engagement programs conducted during both the
Spring and the Fall. This specific outreach in 2023 included detailed phone conversations, written communications, and
in-person meetings with more than 40 top investors and groups. In total, we discussed our sustainability strategy,
commitments and achievements with almost all of the approximately 200 investor groups we met with through personal
conversations, virtual conferences, roadshows, field trips, and group meetings during the year.
• We continued our review of potential technical solutions relating to GHG controls, product improvements and alternate fuels
in 2023; these include carbon capture, artificial intelligence and co-location of green hydrogen production.

• We responded to multiple stakeholder sustainability questionnaires in 2023, including four lengthy surveys requested by
shareholders: Climate Action 100+, CDP, SBTi and Sustainalytics.
