ARQ, INC.
ARQ, INC. is a registered legal entity registered in United States under 4926747, and its current status with Delaware Division of Corporations is active. The company was incorporated on 3 October 2011 and lists its registered address as United States. 5 shareholders are on record for ARQ, 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. This profile is sourced directly from Delaware Division of Corporations and was last updated on 4 October 2026.

Shareholders
5
Five shareholders are currently on record for ARQ, 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 AIGH Capital Management LLC, holding 14.2% — the largest recorded stake — followed by Vanguard Group Inc at 11.4%; the remaining 3 shareholders shown hold 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.

Officers
5
The Ceo, President & Director of ARQ, INC. currently on record is Robert E. Rasmus; five officers are currently on record for ARQ, INC., filed with Delaware Division of Corporations.
The register reports 10 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at ARQ, INC. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
ARQ, INC. has no recorded parent company — it sits at the top of its own group structure, with 21 subsidiaries recorded beneath it across 2 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 21 subsidiaries span United States, United Kingdom 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. Two of the 21 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
