We are proud of the work we have done in the past year, achieving and even surpassing certain of our goals despite the

enterprise that delivers sustainable, long-term value to our stakeholders. We look forward to more conversations with you
about our work to continue strengthening Martin Marietta and its impact, as well as our achievements. We are excited
about our Company’s progress and, while there remains much to do, we know that our partnership with you on this
journey makes us ever more able to conquer whatever challenges lie ahead and to continue making a positive impact on
our communities and environment.

Sincerely,
