Summit Materials
Summit Materials is a Private limited company (Ltd.) registered in United States under 20141166788, and its current status with Colorado Secretary of State is active. The company was incorporated on 13 March 2014 and lists its registered address as Sandy Springs, United States. 5 shareholders are on record for Summit Materials, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Colorado Secretary of State and was last updated on 22 September 2026.

Shareholders
5
Five shareholders are currently on record for Summit Materials, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 13% — the largest recorded stake — followed by Dimensional Fund Advisors LP at 6.6%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
