This page documents the research process behind every ownership profile published on WhoIsTheOwnerOf. If you want to understand exactly how we arrive at a “controlling owner” claim or a shareholder breakdown, this is where to start.
The five-step verification process
Step 1 — Define the entity
Before researching ownership, we define exactly what is being researched. A company’s brand may differ from its operating subsidiary, which may differ from its parent corporation, which may differ from the ultimate beneficial owner. For an article on “who owns Paramount,” we explicitly map: Paramount Pictures (subsidiary) → Paramount Global (listed parent) → National Amusements (controlling shareholder) → Redstone family trust (ultimate beneficial owner). Each layer is documented separately.
Step 2 — Pull primary documents
For US-listed companies, we begin with SEC EDGAR. The relevant filings vary by question:
- 10-K (annual report) — total share counts, executive officers, share class structure
- DEF 14A (proxy statement) — beneficial ownership table, board composition, executive compensation
- 10-Q (quarterly report) — material changes since the last 10-K
- 13D / 13G — any holder of more than 5% of voting stock
- Form 4 — insider transactions
- S-1 — original ownership at IPO (for newer listings)
For non-US listings, we use the equivalent regulator: SEDAR (Canada), Companies House (UK), MCA (India), KAP (Korea), JPX (Japan), HKEX (Hong Kong), ASX (Australia).
For private companies, we use state corporate registries, court filings (where ownership has been disclosed in litigation), and the company’s own published statements.
Step 3 — Triangulate with tier-1 press
Primary documents are necessary but not always sufficient — corporate ownership is often layered across LLCs, trusts, and holding structures. We cross-reference primary disclosures against reporting from independent journalism: Forbes, Bloomberg, Reuters, The Wall Street Journal, Financial Times, Barron’s, and The Economist. For industry-specific questions we add sector outlets (Sportico for franchise valuations, Variety for media, TechCrunch for tech, The Information for tech-private).
Step 4 — Resolve conflicts
If primary documents and press reports disagree, the primary document wins for the date it covers. If two press reports disagree, the more recent one usually wins, but we explicitly note the conflict in the article when one persists. We do not “average” or “split the difference” — we either resolve or disclose.
Step 5 — Date the claim
Every ownership figure we publish carries an “as of” date. For percentages drawn from a 10-K filed February 2026 covering fiscal year 2025, the figure is “as of December 31, 2025” — not “current.” This matters because ownership shifts. Quarterly reverification is built into our update cadence.
How we handle special cases
Family trusts & private holding companies
When ownership traces to a family trust (Redstone family trust controls National Amusements; Walton family trusts control Walmart-adjacent stakes), we research the trust structure where publicly disclosed and acknowledge the limits of public information where it is not. We do not speculate about beneficial allocations within trusts.
Government-backed entities
For state-owned or sovereign-wealth-backed companies (Saudi Aramco, China Mobile, Russian state firms, India’s PSUs), we identify the controlling government entity, the ministry or agency holding the stake, and the relevant published reporting. We do not publish geopolitical commentary.
Cryptocurrency & decentralized organizations
For crypto exchanges and DAO-structured organizations, we focus on the legal entities that hold operating contracts, employment relationships, and regulatory licenses, since “ownership” of a decentralized protocol differs meaningfully from ownership of a corporation.
What we cannot promise
Ownership data is a moving target. Companies merge, sell stakes, restructure trusts, and refile disclosures monthly. We aim for accuracy as of the “Last verified” date stamped on each article, sourced to the documents and reporting we cite. We cannot guarantee real-time accuracy, and a reader making an investment, journalistic, or legal decision should always verify against the underlying primary source themselves.
