Later profile lists add other management, liquidation and personal investment roles, each with its own scope. ## The core official mandates - Analysis: The official retained records show Mühlberger as Holding managing director authorised from 4 April 2013, family foundation board member from 29 October 2014, Supraholding GmbH director from October 2020, SUPRA Assets director from January 2021 and ARP Seventeen director from March 2015. The same person’s offices connect the legal entities; the offices do not make the companies interchangeable or establish responsibility for every allegation mentioned elsewhere in the case.

It separately identifies general-partner roles and liquidation appointments, including Laura Heli and Familie Benko 2017 Zwei. “Current since” profile headers describe the displayed snapshot; they are not necessarily the start date of every mandate. Official records independently give December 2023 for Funds Holding management, October 2023 for Retail Holding, and April 2026 for Innovations Holding liquidation. [s-d31] [s-d54] [s-d55] [s-d56] ## His own investments and foundation classification - Analysis: His retained personal holding profile names Ricchieri Holding at 100% and several property partnerships, including Objekt Kaiser Josefstraße 13 and the Ricchieri German and Austrian partnerships. Separately, an insolvency account lists him in the foundation’s economic-owner category. That classification does not establish personal beneficial ownership or effective control over all foundation assets; it should not collapse the board appointment into an ownership assertion. [s-d31] [s-d9] - Attributed: A retained corporate-role profile lists Marcus Mühlberger owning 100% of Ricchieri Holding and having interests in Gräflich von Dürckheim & Mühlberger’sche Beteiligungs OG, M&S Sachsen Immobilien OG, Objekt Kaiser Josefstraße 13 OG, Ricchieri Deutschland Immobilien Beteiligungs KG, Ricchieri Österreich Immobilien Beteiligungs OG and SIGNA AT 2020 Vier KG.
