/ PROPOSAL 5: ADVISORY VOTE ON A SHAREHOLDER PROPOSAL REGARDING GREENHOUSE GAS EMISSIONS REDUCTION TARGETS

Marietta’s strategic priorities with respect to climate change. We established an Ethics, Environment, Safety and Health
Committee in 1994 whose responsibilities include reviewing Martin Marietta’s climate and other sustainability goals, as
well as Martin Marietta’s sustainability-related performance and engagement with investors.

As noted previously, Martin Marietta is overwhelmingly an aggregates (crushed stone, sand and gravel) business, from the
perspective of our revenue, profitability and the number of facilities we own or operate, including approximately 350
quarries and other aggregates-related facilities. We operate two heritage cement plants only, both located in Texas.
To support its demands during our engagement efforts (including its demands to issue science-based targets), the
proponent has consistently compared Martin Marietta to largely European-based cement companies with substantially
1
larger GHG emissions profiles. As shown by the charts below, however, Martin Marietta has a relatively low GHG
emissions profile compared to those and other cement companies.
