How to read Theo Roussis's profile

Public net-worth figures are estimates. They combine observable inputs—typically listed equity, disclosed transactions, and market prices—with editorial judgment where filings are incomplete (for example, private holdings, debt, or cross-holdings). For Theo Roussis, we anchor the narrative to Plastic and Plastic, then update the headline number as markets move. The chart on this page is meant to show trajectory, not a certified balance sheet.

When you see $3.176B alongside global rank #1326, interpret it as our best synthesis of widely cited ownership and price signals—not a claim about cash on hand. Estimates can diverge from other publishers because of different treatment of options, trusts, charitable vehicles, or illiquid assets. We document the general approach in methodology and welcome corrections via corrections.

Country (BELGIUM) and career milestones on this page are curated for reader context; they should be verified against primary sources when used for research. Editorial metadata for this profile is refreshed on a rolling basis, with deeper audits at least annually (last noted cycle: 2026).

Looking for depth? When available, the dossier and timeline sections below add long-form context beyond the headline number—prioritize those modules when evaluating claims about strategy, controversies, or philanthropic commitments.
