Uncover who holds control, not just who holds shares.
ZENO-Indices turns complex shareholding structures into actionable control intelligence. We identify Ultimate Controlling Owners (UCOs), the shareholders whose real power over a company exceeds what ownership registers suggest.
Robust across jurisdictions and regulatory frameworks
Standard tools show ownership. They do not show control.
A 9% shareholder can exercise dominant control over a company, and remain invisible to every compliance tool your team relies on today. ZENO identifies these actors as Ultimate Controlling Owners (UCOs), distinct from UBOs, and measured by the proprietary ZENO Power Index.
The cost of this blind spot is not theoretical: procurement bodies admit adversarial suppliers. Compliance teams miss sanctions circumvention routes. Fund managers allocate capital to issuers whose governance dynamics have materially shifted. ZENO closes that gap.
Why is control important for your strategic decisions?
Whether you screen suppliers, onboard counterparties, or allocate capital, the question is the same: who actually controls this entity? ZENO answers it.
Your supplier looks clean. Its controlling shareholder may not be.
The problem: A foreign state-linked entity holding 14% of a prime contractor's capital can exercise effective control and remain invisible to standard screening.
ZENO's approach: Z-CAT maps the full shareholding chain, identifies UCOs at each level, and produces an auditable Power Index score for procurement decision-makers.
KYC tools stop at the threshold. Control does not.
The problem: A shareholder coordinating with affiliated entities, or holding pivotal influence in a dispersed capital structure, may exercise real control well below the 25% reporting floor — invisible to standard KYC workflows.
ZENO's approach: The Z-CAT quantifies what declaratory registers do not capture. The EWS detects meaningful shifts in control structure before they surface in public filings.
Ownership structure shapes corporate trajectory. It rarely appears in the investment framework.
The problem: Changes in who controls a listed company often precede visible strategic change by months — yet none of these structural shifts appear in standard financial indicators.
ZENO's approach: The ZPIP delivers systematic UCO and Power Index analysis across a portfolio of listed issuers, producing a structural control signal that standard financial indicators do not capture. The EWS extends coverage with proactive monitoring of material control shifts.
Tax and customs risk models flag transactions. Fraud is orchestrated by people.
The problem: Standard compliance tools assess operators in isolation. A supplier classified as low-risk may be controlled by an entity, or a network of entities, with a very different compliance profile. That connection never surfaces in transaction-based risk models.
ZENO's approach: By mapping the full shareholding chain, Z-CAT identifies the UCOs behind each economic operator and exposes cross-entity control relationships. Risk signals follow people, not just filings, enabling UCO-based segmentation that standard AEO or risk-scoring frameworks cannot produce.
Z-CAT does not aggregate data. It models control.
Z-CAT (ZENO Control Assessment Tool) is the proprietary analytical engine at the core of every ZENO output. It applies ZENO's power measurement methodology to compute the ZENO Power Index for each shareholder in a structure, direct and indirect. The full ownership chain is traced. Cross-held entities are resolved.
The result is a continuous, auditable control score — not a threshold-based flag. Z-CAT's output is interpretable, not a black box, and is designed for regulatory and institutional contexts where analytical traceability is required.
The ZENO Power Index is a continuous measure of effective control. UCO status reflects actual capacity to influence corporate strategy, not ownership percentage alone
