Corporate Governance Board Practices

Who are Martin Marietta’s independent Directors?
All of Martin Marietta’s Directors are non-employee Directors except Mr. Nye. Mr. Nye neither sits in the executive sessions
of the independent Directors (unless invited to attend for a specific discussion) nor does he participate in any action of the
Board relating to any executive compensation which he may receive.

In assessing the independence of its members and nominees, the Board has adopted for Martin Marietta a set of
Guidelines for Director’s Independence (Guidelines). The Guidelines are posted and available for public viewing on Martin
Marietta’s website at https://ir.martinmarietta.com/corporate-governance/governance-documents-and-charters. These
Guidelines reflect the rules of the NYSE, applicable requirements of the SEC, and other standards determined by the Board
to be important in assessing the independence of Board members. The Board has determined that, other than Mr. Nye, all
members of the Board are “independent” under these Guidelines, resulting in 91% of the Board being independent. The
Board of Directors has determined that no Director (except Mr. Nye), or any person or organization with which the
Director has any affiliation, has a relationship with Martin Marietta that may interfere with his or her independence from
Martin Marietta and its management. In making this “independence” determination, the Board considered other entities
with which the Directors were affiliated and any business Martin Marietta had done with such entities.
