MAGILLEM DESIGN SERVICES
MAGILLEM DESIGN SERVICES is a French société anonyme (public limited company) registered under SIREN 492681671 (SIRET 49268167100029), incorporated on 26 October 2006 and registered at 251 rue du Faubourg Saint-Martin, 75010 Paris. The company’s Sirene registry entry still carries the administrative status “active,” but this reflects only that the company has not yet been struck off the register: an extraordinary general meeting held on 19 December 2024 resolved to dissolve MAGILLEM DESIGN SERVICES early and place it into voluntary liquidation with effect from that date, appointing Isabelle Geday as liquidator. The company is therefore in liquidation rather than ordinary trading.
Before its wind-down, MAGILLEM DESIGN SERVICES developed and published software used in semiconductor system-on-chip design, register management and hardware/software-interface automation, classified under French activity code 62.02A (computer systems and software consultancy). From at least 2010 until 2020 its shares traded on Euronext Paris (previously Alternext) under ISIN FR0010827741 and ticker MLMGL/XMLI, consistent with its status as a listed société anonyme.
MAGILLEM DESIGN SERVICES is widely described as having been “acquired” by Arteris IP on 30 November 2020, but Arteris’s own press release specifies that the transaction acquired the company’s assets, not its shares, with substantially all Magillem employees hired into Arteris’s separate French subsidiary, Arteris IP SAS. MAGILLEM DESIGN SERVICES itself continued to exist as an independent, separately listed legal entity for four more years before its December 2024 dissolution.

Shareholders
No individual or corporate shareholders are named in the registry data reviewed for MAGILLEM DESIGN SERVICES. As a French société anonyme, the company’s shareholder register is held privately rather than filed in full with the commercial court, and detailed beneficial-ownership information is recorded in France’s Registre des Bénéficiaires Effectifs (RBE), public access to which has been restricted since 31 July 2024. From at least 2010 until 2020 MAGILLEM DESIGN SERVICES’ shares traded publicly on Euronext Paris (previously Alternext) under ticker MLMGL, ISIN FR0010827741, meaning ownership during that period was at least partly dispersed among public investors, but no historical major-shareholder filing identifying specific holders or percentages was located in the sources reviewed. Following the 19 December 2024 general meeting resolution to dissolve the company and place it into liquidation, no further shareholder disclosures have been identified.
Data availability
Shareholder information for MAGILLEM DESIGN SERVICES is Restricted: France’s Registre des Bénéficiaires Effectifs, the primary source for beneficial-ownership data, has not been publicly searchable since 31 July 2024, and no acquisition announcement, prospectus or other public filing identifying specific shareholders was located. This should not be read as evidence that the company has no shareholders or beneficial owners.

Officers
12
The registry data reviewed for MAGILLEM DESIGN SERVICES lists five officer records out of 14 the underlying source reports holding, four shown as active and one as resigned, so this overview is necessarily partial. The stored records show Isabelle Pesquié as Chairman of the Board and Chief Executive Officer, Emmanuel Vaumorin as Deputy CEO, Christophe Dubois de la Patellière as Administrator (appearing twice, once active and once resigned, apparently reflecting a renewed board term rather than two different people), and Cabinet M.L.P.N., a corporate officer registered in France, as Statutory Auditor. No appointment or resignation dates are recorded for any of these individuals in the stored data. External verification shows this snapshot is now materially out of date: France’s official Sirene company register currently records the same individual as Isabelle Pesquié (born May 1958), now shown under her married name Isabelle Geday, not as Chairman/CEO but as Liquidateur (liquidator), following the company’s December 2024 dissolution.
Recent officer changes
By decision of the general meeting of 19 December 2024, MAGILLEM DESIGN SERVICES was placed into early dissolution and voluntary liquidation with effect from that date, and Isabelle Geday (Pesquié) was appointed liquidator in place of her prior role as Chairman of the Board and Chief Executive Officer, as published via the BODACC official legal-announcements gazette and reflected in the current INSEE Sirene register.
Data availability
Officer disclosure for MAGILLEM DESIGN SERVICES is Partial: the stored registry snapshot includes only 5 of the 14 officer records the source reports holding, none carrying appointment or resignation dates, and it predates the December 2024 dissolution and change of liquidator. Nationality is not disclosed for any individual in the sources reviewed and has not been inferred from any name, address or country field; the addresses shown are correspondence addresses only, not residences.

Group Structure
No verified parent company, subsidiary or other corporate-group relationship is recorded for MAGILLEM DESIGN SERVICES in the registry data reviewed, consistent with the company’s history as an independently listed société anonyme rather than a group subsidiary. MAGILLEM DESIGN SERVICES is widely reported to have been “acquired” by Arteris IP in November 2020, but Arteris’s own 30 November 2020 press release specifies that the transaction acquired the assets of Magillem Design Services, not its shares, and states that substantially all Magillem employees were hired into Arteris’s existing French subsidiary, Arteris IP SAS, a separate legal entity. An asset purchase does not establish Arteris IP, Arteris, Inc. or Arteris IP SAS as the parent of MAGILLEM DESIGN SERVICES (SIREN 492681671): the French entity continued to exist independently, remained listed on Euronext Paris, and was not dissolved until its own general meeting resolved to liquidate it four years later, on 19 December 2024.
Recent structural changes
On 30 November 2020, Arteris IP completed the acquisition of the business assets (not the shares) of MAGILLEM DESIGN SERVICES, integrating them as its “IP Deployment Division” and transferring substantially all Magillem staff to Arteris’s separate French subsidiary, Arteris IP SAS; this was an asset transaction and is not presented here as a corporate parent-subsidiary relationship. On 19 December 2024, the general meeting of MAGILLEM DESIGN SERVICES resolved to dissolve the company early and place it into voluntary liquidation, appointing Isabelle Geday as liquidator.
Data availability
Group-structure information for MAGILLEM DESIGN SERVICES is Not found: no official filing identifies a current parent company, subsidiary or sister company for this legal entity. The absence of a recorded corporate-group relationship should not be read as proof that none exists.
