AMERESCO, INC.
AMERESCO, INC. is a registered legal entity registered in United States under F00000005646, and its current status with Florida Department of State — Sunbiz is active. The company was incorporated on 4 October 2000 and lists its registered address as Framingham, United States. 3 shareholders are on record for AMERESCO, INC., 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.

Shareholders of AMERESCO, INC.
Three shareholders are currently on record for AMERESCO, INC., 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 9.5% — the largest recorded stake — followed by GMO TRUST-GMO Resources Fund at 2.4%; the remaining 1 shareholder shown holds smaller stakes. 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.

Data availability
Those 639 subsidiaries span United States, Canada, Romania, Spain, United Kingdom, Italy jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Six of the 639 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
