CLEARSIGN TECHNOLOGIES CORPORATION
CLEARSIGN TECHNOLOGIES CORPORATION is a registered legal entity registered in United States under 7513798, and its current status with Delaware Division of Corporations is active. The company was incorporated on 6 February 2024 and lists its registered address as United States. 4 shareholders are on record for CLEARSIGN TECHNOLOGIES CORPORATION, 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 9 October 2026.

Shareholders
4
Four shareholders are currently on record for CLEARSIGN TECHNOLOGIES CORPORATION, reflecting the stock ledger kept by the company 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 25.6% — the largest recorded stake — followed by Fidelity Concord Street Trust-Fidelity Extended Market Index Fund at 4.6%; the remaining 2 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.

The Ceo, Corporate Secretary & Director of CLEARSIGN TECHNOLOGIES CORPORATION currently on record is Colin James Deller Ph.d.; five officers are currently on record for CLEARSIGN TECHNOLOGIES CORPORATION, filed with Delaware Division of Corporations.
The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.

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
CLEARSIGN TECHNOLOGIES CORPORATION has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary 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 1 subsidiary spans United States, Hong Kong 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.
