Gregoire Poux Guillaume Net Worth 2026 Estimate and Sources

Based on the most recent available data, Gregoire Poux-Guillaume's estimated net worth is approximately $4 million (USD), as of April 29, 2026. That figure comes primarily from his disclosed equity stake in AkzoNobel N.V., where he serves as CEO, and reflects publicly trackable holdings rather than a full picture of his private wealth.

Who is Gregoire Poux-Guillaume?

Gregoire (Greg) Poux-Guillaume is a French national, born in January 1970, with a career spanning some of Europe's largest industrial companies. He was appointed CEO of AkzoNobel N.V., the Dutch paints and coatings giant, effective November 1, 2022, a move widely covered by Reuters and confirmed in AkzoNobel's own shareholder biography materials. Before that, he served as CEO of Sulzer, the Swiss industrial engineering company, from 2015. Earlier in his career, he led GE Grid Solutions following GE's acquisition of Alstom's energy businesses, and before that he ran Alstom Grid. It is worth flagging this clearly: there are a handful of people with similar or partially overlapping names in French business circles. Gregoire Poux-Guillaume specifically refers to this individual, the current AkzoNobel CEO with the documented career history above. He should not be confused with Guillaume Pousaz, the fintech entrepreneur behind Checkout.com, whose net worth sits in an entirely different league, nor with Guillaume V, Grand Duke of Luxembourg. The identity is distinct and well-documented through corporate governance filings.

What 'net worth' actually means here

Net worth, at its most basic, is total assets minus total liabilities. For an individual, assets typically include cash and bank balances, investment portfolios, equity stakes in public or private companies, real estate, and other valuables. Liabilities include outstanding debt, mortgages, tax obligations, and any known legal settlements. The result is a snapshot of financial position at a specific point in time, not a permanent figure.

For a public company executive like Poux-Guillaume, one slice of that picture is verifiable: the equity he holds in the publicly traded company where he works. That stake has a real-time market value anyone can calculate. Everything else, including cash savings, private investments, real estate, and debt, is either partially disclosed or entirely private. This is why published net worth figures for executives at this level should always be treated as estimates with a floor that can be confirmed, not a precise total.

Where net worth estimates come from for executives like this

For senior corporate executives, the most reliable starting point is disclosed equity in publicly listed companies. Regulatory filings, insider ownership disclosures, and corporate governance documents give a traceable share count and a market-price-based valuation on any given date. Beyond that, estimators draw on career income history (executive compensation is often disclosed in annual reports), known real estate holdings from property registries, and any other public financial signals.

In Poux-Guillaume's case, French property records via Pappers show a linked entity called SCI ROYALE SAINTE ANNE (registered in Paris, activity: real estate), which suggests some real estate involvement, as is common for executives at this level. SCIs (Sociétés Civiles Immobilières) are a standard French vehicle for holding residential or investment property. However, the specific asset values inside that structure are not publicly disclosed, so it adds context without adding a hard number.

How this site calculates and validates the estimate

The methodology used here follows a balance-sheet approach: start with what can be verified, then apply reasonable assumptions for what cannot. For Poux-Guillaume, the anchoring data point is his AkzoNobel shareholding. MarketScreener's insider profile records 74,359 shares in AkzoNobel N.V. representing approximately 0.04% of the company, with a valuation date of April 29, 2026, producing a figure of roughly $4 million for that holding alone.

From there, the estimate accounts for known liabilities including likely tax obligations on executive compensation, and adjusts for market movements where a significant publicly traded holding exists. Executive compensation packages (base salary, bonuses, and long-term incentive plans) for a CEO of a major European industrial company in this revenue tier typically range from several hundred thousand to well over a million euros annually, some of which is delivered as equity that may or may not be captured in disclosed shareholding data depending on vesting schedules. Private investments, savings, and real estate values are not deducted or added precisely because they are not disclosed. The $4 million figure therefore represents a verifiable floor grounded in publicly confirmed equity, not a ceiling.

Current estimated net worth: the number and what supports it

The most defensible current estimate for Gregoire Poux-Guillaume's net worth is in the range of $4 million to $10 million. If you are specifically searching for Guillaume Lemay Thivierge net worth, note that most published figures depend on verifiable holdings and dated snapshots like the ones used in executive net worth estimates here. The lower bound is supported directly by the disclosed AkzoNobel equity stake. The upper bound reflects a reasonable but unverified addition for accumulated career compensation over a decade-plus as a major industrial CEO, likely real estate holdings (given the Paris SCI), and general savings and investment assets common at this career level. It is not a billionaire-tier figure, and nothing in the available public record suggests otherwise. His situation is quite different from, say, Guillaume Pousaz, whose Checkout.com stake puts estimated wealth in the multi-billion dollar range.

Why the number is uncertain and how it can change

A few important caveats are worth being direct about. First, Poux-Guillaume is not a billionaire and is not tracked by Forbes or Bloomberg Billionaires, which means there is no continuous real-time update to his estimate the way there is for, say, a tech founder with a massive listed company stake. The MarketScreener figure is timestamped April 29, 2026, meaning it was accurate to AkzoNobel's share price on that date. AkzoNobel's stock price moves daily, so the equity portion of the estimate drifts continuously.

Second, the real estate and private investment side is opaque. The Paris SCI is a real data point but gives no asset value. French property values in premium Paris locations can be significant, but without a disclosure or transaction record, no number can be responsibly attached. Third, executive compensation at publicly listed European companies is disclosed in annual reports, but the exact amount varies year to year, and unvested equity awards complicate the total. Any figure you see on a third-party aggregator site without clear sourcing should be treated skeptically.

Finally, estimates across different sites frequently disagree because they use different methodologies, different snapshot dates, and different assumptions about undisclosed assets. A site showing $8 million and a site showing $4 million may both be reasonable depending on what they are including. The $4 million figure from MarketScreener is the most clearly sourced and dated estimate publicly available as of May 2026.
