Accelleron Industries Ag
Accelleron Industries AG is a Swiss stock corporation (Aktiengesellschaft) registered in the commercial register of the Canton of Aargau under UID/CHE-270.303.139, with its registered seat in Baden, Switzerland. The company was incorporated on 26 May 2021 under the name Turbo Systems Holding AG and was renamed Accelleron Industries AG ahead of its stock-market listing; it is recorded as active. Its registered purpose is to hold and manage investments in entities engaged in the design, development, manufacture, sale, maintenance and service of turbochargers and turbocharging systems, and in related digital products, services and software.
Accelleron Industries AG is the listed holding company of a group that designs, manufactures and services turbocharging systems, fuel-injection equipment and digital monitoring solutions for large diesel and gas engines used in marine propulsion, stationary power generation, rail traction and other heavy-duty industrial applications. Per its 2025 annual report, the group is organised into two reporting segments, Medium & Low Speed and High Speed, covering turbochargers spanning roughly 0.5 to more than 80 megawatts of engine output, and reports an installed base of more than 190,000 turbocharger units built on more than a century of turbocharging engineering history.
The business originated as ABB Ltd’s turbocharging division. ABB announced its intention to separate the business on 20 July 2022; ABB shareholders approved the spin-off at an extraordinary general meeting on 7 September 2022; and the transaction completed on 3 October 2022, when ABB distributed Accelleron shares to its own shareholders as a dividend in kind, at a ratio of one Accelleron share for every 20 ABB Ltd shares held. Accelleron Industries AG shares (ISIN CH1169360919, ticker ACLN) were admitted to trading on the SIX Swiss Exchange the same day.
For the financial year ended 31 December 2025, the Accelleron group reported consolidated revenue of USD 1,263.1 million, up 23.5% year-on-year, and an operational EBITA margin of 25.4%, with more than 3,200 employees across roughly 100 locations in about 50 countries. These are consolidated Accelleron group figures rather than standalone results of Accelleron Industries AG, which functions as the group’s Swiss-listed parent entity. Active commercial-register status does not by itself indicate that the company is currently trading or financially stable.

Shareholders of Accelleron Industries AG
Accelleron Industries AG is listed on the SIX Swiss Exchange, and Swiss financial-markets law (the Financial Market Infrastructure Act) requires only shareholders whose voting-rights interest crosses defined thresholds, starting at 3%, to disclose their holdings to the company and to the SIX Swiss Exchange Disclosure Office; a complete register of every individual shareholder is not publicly available. Accelleron Industries AG’s own share information states that 94,500,000 registered shares are outstanding, each carrying one vote and a nominal value of CHF 0.01, and directs investors to the SIX Swiss Exchange Disclosure Office’s significant-shareholder notification database for the current list of reportable holdings. The company’s shareholder base originated from the distribution of Accelleron shares to ABB Ltd’s own shareholders on a pro-rata basis when Accelleron was spun off from ABB on 3 October 2022 (see the group-structure section for that history), which produced a broad, dispersed shareholder register rather than a single controlling holder. Corporate governance disclosures in Accelleron’s annual reports name BlackRock, Inc. among the holders that have crossed a reportable threshold, but the sources reviewed for this profile did not include a specific, dated percentage figure for that or any other individual shareholder, so no holding percentage is reported here.
Data availability
Shareholder information for Accelleron Industries AG is classified as Major shareholders only: as a SIX-listed company, only holdings that cross the statutory disclosure thresholds are made public, and the complete underlying shareholder register is not published. No single reportable shareholder is confirmed to hold a controlling stake, and ABB Ltd retained no shares in Accelleron following the completed spin-off distribution.

Group Structure
Group structure of Accelleron Industries AG
Accelleron Industries AG is a publicly listed, Swiss-domiciled holding company; no immediate or ultimate parent company above it was identified in the sources reviewed, and its registered purpose is to hold and manage investments in operating group companies. Accelleron Industries AG was previously part of the ABB group as ABB Ltd’s turbocharging division (formerly branded ABB Turbocharging) until the business was spun off as an independent, separately listed company on 3 October 2022; ABB Ltd distributed all Accelleron shares to ABB’s own shareholders at that time and retained no ownership stake in Accelleron, so this is reported here as a historical relationship rather than a current ownership link. Accelleron’s own subsidiary disclosure lists group operating entities carrying the Accelleron name (or, in Switzerland, “Accelleron Switzerland Ltd” and “Accelleron Verwaltungs Ltd”) in approximately 50 countries, consistent with the group’s reported footprint of roughly 100 locations; exact equity percentages for these entities are set out in Note 25 to the consolidated financial statements in Accelleron’s annual report, which was not available in full text in the sources reviewed for this profile. A verified direct acquisition is Officine Meccaniche Torino S.p.A. (OMT), an Italian manufacturer of fuel-injection systems for marine engines based in Turin, which Accelleron acquired in its entirety in 2023; OMT subsequently acquired O.M.C. 2 Diesel S.p.A. (OMC2), an Italian fuel-injection manufacturer based in Brescia, in 2024.
