centrotherm international AG
centrotherm international AG is a German public company registered in the Handelsregister (commercial register) of the Amtsgericht Ulm under number HRB 720013, with its registered seat in Blaubeuren, Baden-Württemberg (89143). It was incorporated on 30 March 2006 as an Aktiengesellschaft (AG, a German stock corporation) and its status on file is active. centrotherm international AG is the parent of the centrotherm Group, which develops and manufactures production equipment and thermal process technology for the semiconductor, microelectronics and photovoltaics industries, with applications extending into battery and specialty-fiber production; the group reported consolidated revenue of about EUR 211.1 million and more than 700 employees worldwide for fiscal year 2025.
The company began as centrotherm photovoltaics AG, listed on the Frankfurt Stock Exchange Prime Standard in October 2007 and added to the TecDAX index in December 2007. Under severe pressure in the solar-equipment market, it applied for a Schutzschirmverfahren (a self-administered protective-shield insolvency proceeding under Germany’s ESUG law); the Amtsgericht Ulm approved the proceeding on 12 July 2012, the restructuring/insolvency plan was confirmed on 29 January 2013, and the court formally terminated proceedings on 31 May 2013. The company was renamed centrotherm international AG in June 2017.
Its long-time majority shareholder, Solarpark Blautal GmbH (linked to the founding Hartung family), sold its approximately 90% stake to an acquisition vehicle backed by investment firm Ardian (signed 6 November 2025, closed 17 December 2025). A merger-law squeeze-out of remaining minority shareholders was approved at the 30 June 2026 annual general meeting. As of this writing, centrotherm international AG shares remain admitted to trading on the Frankfurt Stock Exchange Open Market (Freiverkehr/Basic Board, ISIN DE000A1TNMM9); delisting is planned once the merger is registered in the commercial register.

Shareholders
For a German Aktiengesellschaft such as centrotherm international AG, the shareholder register is not filed publicly with the Handelsregister, and beneficial-ownership detail in the Transparenzregister is restricted to parties with a legitimate interest, not the general public. No independent primary confirmation of the current register was accessible.
Company ad-hoc disclosures (not registry filings) report that since a transaction closed 17 December 2025, an acquisition vehicle backed by funds managed by Ardian (via Ardian Semiconductor) holds approximately 90% of centrotherm international AG’s share capital, purchased from the prior long-time majority holder Solarpark Blautal GmbH, linked to the founding Hartung family. The same disclosures report the Hartung family reinvested part of the proceeds, retaining a reported indirect interest (~39.5%) in the acquisition structure, distinct from any direct shareholding. A merger-law squeeze-out of remaining minority shareholders was approved at the 30 June 2026 AGM but is not yet effective, pending registration of the merger in the commercial register.

Officers
38
Handelsregister and current corporate disclosures show a two-member Vorstand (Management Board): Jan von Schuckmann (Vorstandsvorsitzender / CEO), whose service agreement was renewed early by the Supervisory Board on 13 March 2025 for a new term running 1 April 2025 to 31 March 2030; and Dr. Helge Haverkamp (Chief Technology Officer), in office since 1 September 2021.

Current Aufsichtsrat (Supervisory Board): Dr. Helmut Gassel (Chairman) and Stefan Kappis (Deputy Chairman), both elected 23 January 2026 after prior members Hans-Hasso Kersten and Dr. Xinan Jia resigned 17 December 2025 amid the change of control; Robert M. Hartung continues as a member.

Group Structure
Germany: no public registry (Handelsregister) filing of a full group/ownership chart was accessible for centrotherm international AG, and the company’s on-file registry data records no parent, subsidiary, or ownership linkage.
Company disclosures indicate centrotherm international AG is the parent of an operating “centrotherm Group” — its consolidated results (revenue, order backlog, headcount) are reported on a group basis, implying operating subsidiaries, but no primary source itemizing those entities was found for this profile. On the ownership side, as of 17 December 2025 an acquisition vehicle backed by investment firm Ardian holds approximately 90% of centrotherm international AG, having bought that stake from Solarpark Blautal GmbH (linked to the founding Hartung family); a merger-law squeeze-out of the remaining minority shareholders was approved at the 30 June 2026 annual general meeting and, once registered, would merge centrotherm international AG into the acquiring vehicle. That registration was not yet confirmed as of the information date below.
