Martin Marietta Materials has confirmed Christopher W. Samborski will be the company’s next chief operating officer.
Samborski will take on the new role from May 1 after serving as president of Martin Marietta’s west and specialties divisions with a remit across both operations for their strategic direction.
“Chris is an experienced and skilled leader whose effective management has had a meaningful impact on Martin Marietta,” Martin Marietta chair and chief executive officer Ward Nye said.
“Chris has been with our Company for nearly a decade, and he has consistently demonstrated a true commitment to Martin Marietta, our people, our culture and our ongoing pursuit of excellence. He is the ideal person to take on the COO role and to continue leading, alongside our deeply capable and talented team, as we guide our Company to even greater success.”
Samborski joined the US aggregates and building materials producer in 2018, but prior to joining the company, he worked at Caterpillar Inc. and Johnson & Johnson. With Samborski’s elevation, Kirk Light will take on the leadership of the west and specialties divisions as well as being president of the southwest division.
“I’m honoured to take on this new opportunity, particularly during this period of strong performance and growth for our business,” Samborski said.
“Martin Marietta closed out 2025 by delivering record results across the portfolio, and I look forward to working closely with our teams to build on this positive momentum in 2026 and beyond.”
