SYSTEM1, INC. is a registered legal entity registered in United States under 6571125, and its current status with Delaware Division of Corporations is active. The company was incorporated on 1 February 2024 and lists its registered address as United States. 3 shareholders are on record for SYSTEM1, 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

3

Three shareholders are currently on record for SYSTEM1, 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 Communication Services Index Fund, holding 8.6% — the largest recorded stake — followed by Healthcare of Ontario Pension Plan Trust Fund at 0.8%; 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.

The Ceo & Chairman of SYSTEM1, INC. currently on record is Michael L. Blend; five officers are currently on record for SYSTEM1, INC., filed with Delaware Division of Corporations.

The register reports 11 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

SYSTEM1, INC. has no recorded parent company — it sits at the top of its own group structure, with 9 subsidiaries recorded beneath it across 1 jurisdiction. 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 9 subsidiaries span United States jurisdiction, 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.
