Martin Marietta Materials, Inc. (MLM) — Stock Score Summary

Martin Marietta Materials, Inc. (MLM) has a MoatMap StockRank of 51/100 based on Quality (61/100), Value (26/100), and Momentum (50/100) factor scores. The current signal is HOLD. Martin Marietta holds an irreplaceable network of aggregates quarries in high-growth US economic corridors. As the US undergoes a structural re-shoring boom—requiring massive new semiconductor fabs, gigafactories, and grid infrastructure—aggregates are a critical, non-importable input. Due to high weight-to-value ratios, local quarries possess immense pricing power and high ROIC, fitting the Terry Smith and Buffett criteria perfectly.

Martin Marietta Materials, Inc. is a leading supplier of building materials, primarily crushed stone, sand, and gravel (aggregates), along with downstream products like ready mixed concrete and asphalt, crucial for infrastructure and non-residential construction. The company's competitive moat stems from its extensive, strategically located quarry reserves and the high transportation costs of aggregates, which localize competition and create regional monopolies. As a major player, Martin Marietta is well-positioned to benefit from ongoing infrastructure investment across the United States.

Martin Marietta Materials, Inc. operates in the Building Materials industry, part of the Basic Materials sector (United States).
