DASSAULT SYSTEMES

Shareholders of Dassault Systèmes SE

Dassault Systèmes SE is a listed issuer, so what is published is the register of holders above the disclosure thresholds rather than the whole shareholder base. Its 2025 Document d’enregistrement universel, filed with the Autorité des marchés financiers on 31 March 2026, gives the position at 31 December 2025 against 1,341,806,268 shares of €0.10 nominal value, 2,013,578,477 theoretical voting rights and 1,992,457,305 exercisable voting rights. Capital and voting rights diverge because article 29 of the bylaws grants a double voting right to every fully paid share held in registered form in the same name for at least two years.

Within that free float, the most recent AMF declaration of a major holding (franchissement de seuil) is décision 226C0474 of 9 April 2026: First Eagle Investment Management, LLC, acting for clients and managed funds, crossed the 5% capital threshold upward on 2 April 2026 and held 67,465,881 shares, being 5.02% of the capital and 3.35% of the voting rights. It is the only AMF threshold declaration published for this issuer since 2011. Under the 2.5% statutory threshold in the bylaws, the company also records notifications from MFS Investment Management (17 September 2015), First Eagle Investment Management (19 February 2026) and BlackRock, Inc. (11 March 2026). The company’s monthly declaration of 3 September 2026 puts the totals at 1,342,915,029 shares and 2,018,713,316 voting rights as at 31 August 2026.

Ultimate beneficial ownership

No natural person is published as an ultimate beneficial owner with an effective percentage. The French registre des bénéficiaires effectifs has not been open to the general public since the Court of Justice of the European Union ruling of 22 November 2022, and for a listed French issuer controlling positions are instead disclosed through AMF threshold declarations and the registration document. On that basis, the issuer’s own 2025 registration document states that Groupe Industriel Marcel Dassault SAS belongs to the Dassault family, that its supervisory board is composed and chaired exclusively of family members, and that with more than 50% of the voting rights held by GIMD “the Dassault family ultimately controls Dassault Systèmes”. That is a control statement by the issuer, not an identification of a named beneficial owner, and no ownership chain permitting a calculated effective percentage for any individual is published.

Data availability

Availability is major shareholders only. Holdings below the 2.5% statutory threshold are not individually published; an external study commissioned by the company counted 651 institutional investors holding more than 3,000 shares each and together 42.7% of the capital at 31 December 2025, without naming them.

The baseline gd_shareholders record on this page should not be read as ownership. It holds nine rows, all US-domiciled investment funds and advisers with US-dollar share prices, consistent with holdings of the DASTY American Depositary Shares rather than with the French share register. Their quantities total 31,299,802 shares, about 2.33% of the shares in issue at 31 December 2025, yet the percentages stored against them sum to 45.81%. Individual rows are stated at 13.53%, 13.51% and 13.14%, figures no holder of this issuer has declared. Groupe Industriel Marcel Dassault, Charles Edelstenne and Bernard Charlès — together more than 48% of the capital — do not appear in the stored rows at all. The stored percentages do not reconcile with the shares in issue and are not published here.

Directors and officers of Dassault Systèmes SE

Dassault Systèmes SE is a société européenne administered by a single Conseil d’administration. The company’s 2025 Document d’enregistrement universel, filed on 31 March 2026, describes a board of 13 members serving renewable four-year terms, and proposed the appointment of a fourteenth at the general meeting of 20 May 2026. The Registre national des entreprises, updated 22 September 2026, records fourteen serving administrateurs: Pascal Daloz (Président-Directeur Général), Charles Edelstenne, Geneviève Berger, Xavier Cauchois, Catherine Dassault, Laurence Daures, Soumitra Dutta, Marie-Hélène Habert-Dassault, Nathalie Rouvet Lazare, Donatella Sciuto, Éric Trappier, the two employee-representative directors Anne-Laure Chevalier and Christine Defert, and one corporate director, Groupe Industriel Marcel Dassault SAS (SIREN 400 628 079), whose permanent representative is Olivier Costa de Beauregard. Six of the thirteen non-employee directors are classified as independent and the board reports 55% independence.

Nationality is explicitly disclosed for each director in the registration document: Soumitra Dutta is recorded as Indian and Donatella Sciuto as Italian; the remaining directors listed in the 2025 board table are recorded as French. Éric Trappier joined after that table was compiled and his nationality is not stated there. The two statutory auditors are PricewaterhouseCoopers Audit (first appointed 8 June 2005, renewed 24 May 2023) and KPMG S.A. (first appointed 19 May 2022); both are corporate appointments, not natural persons, and an auditor is not a director.

Recent officer changes

• 21 February 2026 — Bernard Charlès informed the board that he was standing down as Chairman of the Board and as a director with immediate effect, for personal reasons. The board appointed Pascal Daloz, then Chief Executive Officer, as Président-Directeur Général (Chairman and Chief Executive Officer) with effect from 21 February 2026. Source: company press release of 21 February 2026 and registration document §5.1.1.1.
• 22 May 2025 — Marie-Hélène Habert-Dassault, Nathalie Rouvet Lazare and Donatella Sciuto were appointed directors. Marie-Hélène Habert-Dassault had previously been a director in her own name from 2014 to May 2024 and then permanent representative of Groupe Industriel Marcel Dassault from May 2024 to 8 January 2025.
• 20 May 2026 — the appointment of Éric Trappier as a director was put to the general meeting; the Registre national des entreprises records him as a serving administrateur in its 22 September 2026 update.

Data availability

Availability is full for this company: the registration document publishes each director’s role, independence, first appointment date, term expiry and nationality, and the Registre national des entreprises carries the current list free of charge. Dates of birth are published by the register but only month and year are reproduced here, and no national identifiers are reproduced.

The baseline gd_officers record on this page is unreliable and should not be read as the current board. It holds 93 rows for a fourteen-member board, with heavy duplication — Bernard Charlès appears nine times under three spellings — and of the 79 rows flagged RESIGNED, 78 carry no resignation date at all. Fourteen rows are flagged ACTIVE, and two of them are wrong: Bernard Joseph Marie Charles is still shown as an active “Chairman Of The Board Of Directors” although he left both offices on 21 February 2026, and Odile Parfait is shown as an active Administrator although she does not appear on the current board in either the registration document or the register. Four serving directors — Éric Trappier, Nathalie Rouvet Lazare, Donatella Sciuto and Marie-Hélène Habert-Dassault as a director in her own name — are absent from the active rows. The record also mixes statutory mandates with operational management titles such as executive vice-presidents and divisional chief executives, who are not mandataires sociaux, and types the audit firms ERNST & YOUNG ET AUTRES and AUDITEX with the job title “Director”. One name is corrupted by character loss (“Sgolne Moignet”), and Soumitra Dutta’s row carries the address country FR with an Oxford locality, whereas the registration document gives his professional address as Washington, DC.

Group structure of Dassault Systèmes SE

Dassault Systèmes SE is the consolidating parent of the Dassault Systèmes group and is not itself consolidated into any entity disclosed in its own filings. Above it sits a controlling shareholder: Groupe Industriel Marcel Dassault SAS (SIREN 400 628 079), which held 39.91% of the capital and 53.75% of the exercisable voting rights at 31 December 2025 and also holds a seat on the board. Note 21 to the parent-company accounts in the 2025 Document d’enregistrement universel lists sixteen companies more than 50% directly held by Dassault Systèmes SE, carried at €7,247.7 million net. Note 28 to the consolidated accounts names 29 principal consolidated subsidiaries across Germany, Australia, Canada, China, South Korea, Spain, the United States, France, India, Italy, Japan, Malaysia, the Netherlands, Poland, the United Kingdom, Singapore, Sweden, Switzerland and Taiwan. Ownership percentages below are those stated in the filings at 31 December 2025; the ArisGlobal transaction announced on 23 July 2026 is not reflected in them.

Verified corporate relationships

Recent structural changes

• 4 April 2025 — Amcad Engineering SAS was absorbed into Dassault Systèmes SE by transmission universelle de patrimoine, part of a stated programme of simplifying the group’s legal structures; a merger deficit of €1.9 million was recognised.
• September 2025 — following the exercise of put options by minority holders, Dassault Systèmes SE exchanged treasury shares for Centric Software, Inc. securities and then sold those securities to Dassault Systemes Americas Corp., Centric Software’s parent.
• 23 July 2026 — a definitive agreement was signed to acquire ArisGlobal for approximately US$1.8 billion in cash plus up to US$200 million of contingent consideration, subject to regulatory and other customary conditions. No completion is recorded in the issuer’s regulated filings as at 29 September 2026, so ArisGlobal is not presented here as a group company.

Data availability

Availability is partial. France publishes the legal unit and its establishments free of charge but not a corporate-linkage register, so the structure has been rebuilt from the issuer’s own filed accounts. Those accounts give percentages for the sixteen direct subsidiaries and name 29 principal consolidated entities, but they do not publish the full consolidation scope, registration numbers for foreign subsidiaries, or the intermediate holding chains. Registration numbers above are shown only where they were verified against a register; the remainder are marked as unverified rather than copied from the stored tree.

Two defects in the baseline data on this page are worth recording. The stored gd_groups tree holds 85 nodes with the company at the root and 84 descendants, but carries no ownership percentage on any node and no relationship type, so it cannot distinguish a direct subsidiary from an indirect one. Its identifiers are also heterogeneous: for the French nodes it stores 14-digit SIRETs rather than SIRENs — the company’s own node reads “FR 32230644000213” — while other nodes carry VAT numbers, tax identifiers or internal placeholder strings beginning with “#”. At least one node, Trust Management Advisors-Stratorg, names a legal unit that ceased on 10 July 2026, its radiation published in BODACC on 24 July 2026. Separately, the stored gd_website value points to a deep French-language consulting-services page on the company’s own domain rather than to the corporate site, which the registration document gives as www.3ds.com, and gd_legal_form is empty although the registration document states the form plainly as société européenne (Societas Europaea).
