Canonical: https://valuechain.wiki/martin-marietta-materials · Facet: ripple · Updated: 2026-09-23T07:31:38.954831+00:00 · Source: ValueChain.wiki (cited money-flow graph)

**Citable summary**: Per the valuechain.wiki graph, Martin Marietta Materials, Inc. is directly linked to 3 companies (3 supply, 1 revenue relationships) and reaches 10 companies within two hops; the links are backed by 7 dated sources, 1 of them primary filings (as of 2026-09-23).

Martin Marietta Materials, Inc. operates across U.S. aggregates-led materials. After +21.3% in 2025, it corrected -17% in 2026. The supply side (avg +32.8%) has moved harder than the stock (-17%). That is the classic bottleneck pattern: supplier volume leverage is being priced before this layer's own margin. Among connected nodes the furthest ahead is Caterpillar (+42.9%) and the furthest behind is Union Pacific Corporation (+27.1%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. It spends on quarry equipment and rail logistics and expands its supply base through aggregates and specialty-materials acquisitions.
