DEME Group NV (DEME.BR) - Institutional Ownership and Major Shareholders of DEME Group NV (DEME.BR)

DEME Group NV exhibits a concentrated ownership profile dominated by strategic and long-term industrial shareholders, alongside a modest institutional base and a public free float that supports tradability.

• Ackermans & van Haaren NV: 62.12% (controlling shareholder)
• VINCI Construction SAS: 12.11% (strategic industrial partner)
• Institutional investors (aggregate, incl. Vanguard, JP Morgan AM, BlackRock): ~14.00%

Ownership concentration: the top two holders control 74.23% of shares (62.12% + 12.11%), leaving a relatively small dispersion among other holders. This structure tends to:

• Support strategic, long-horizon decision-making driven by a dominant industrial shareholder.

• Provide sufficient public float (25.59%) for secondary-market liquidity, though turnover may be lower than peers with wider distributions.

Why these buyers hold positions:

• Ackermans & van Haaren - maintain strategic control of an infra-heavy business with synergies across its industrial portfolio.
• VINCI Construction - align on project partnerships, technology and contracting pipelines.
• Institutions (Vanguard, JP Morgan, BlackRock) - allocate via index/ETF exposure, infrastructure thematic funds, and diversified active strategies seeking stable cash flows and long-term projects.
