Duroc Aktiebolag
Duroc Aktiebolag, trading as Duroc AB, is a Swedish public limited company (aktiebolag (publ)) registered with the Swedish Companies Registration Office (Bolagsverket) under organisation number 556446-4286. The company was registered on 8 April 1992 and its registration status is currently active. Duroc Aktiebolag’s registered postal address is Box 5277, SE-102 46 Stockholm, with its office located at Linnégatan 18 in Stockholm.
Duroc operates as a long-term investment and holding company that acquires, develops and manages industrial and trading businesses in Europe and the United States. Rather than running a single operating business itself, Duroc Aktiebolag holds and oversees a group of decentralised subsidiary companies, each retaining a degree of entrepreneurial autonomy under local management. Its portfolio spans machine tools and machine-tool services (Duroc Machine Tool), railway-wheel maintenance for locomotives and rolling stock (Duroc Rail), coated and technical textiles and polypropylene-based fibre products (International Fibres Group and related companies), and a number of smaller industrial and trading businesses. Through these holdings, the group serves customers in the engineering, rail transport, textile and industrial-trade sectors.
Duroc’s Class B share is listed on Nasdaq Stockholm’s Small Cap segment under the ticker DURC B, with a Class C share also in issue; no Class A shares are currently outstanding. This is a company-level listing detail rather than a statement about the operating scale of any individual subsidiary.
For the financial year 2024/2025, the Duroc group reported consolidated net revenue of SEK 3,013.8 million (2023/2024: SEK 3,111.1 million) and consolidated operating profit of SEK 32.1 million (2023/2024: SEK 46.4 million), according to the group’s annual and sustainability report. These figures represent the consolidated performance of the Duroc group rather than the stand-alone financial results of Duroc Aktiebolag as a legal entity, which functions primarily as the group’s holding company.

Shareholders
Shareholders of Duroc Aktiebolag
According to Duroc AB’s own published shareholder table, as of 30 June 2026 the company’s largest shareholder was Bronsstädet AB, holding 21,066,783 Class B shares and 9,933,217 Class C shares, equal to approximately 79.5% of capital and voting rights. Other disclosed major shareholders included AB Traction (approximately 5.2%), Henrik Strid (approximately 1.6%), Thomas Blixt (approximately 1.5%) and Nordnet Pensionsförsäkring AB (approximately 1.0%). Duroc’s Class B share is listed on Nasdaq Stockholm, and all share classes carry equal voting rights of one vote per share. The published table lists the largest shareholders rather than the company’s complete shareholder register, so smaller holdings are not individually disclosed.
Ultimate beneficial ownership
Swedish company-registry sources record Peter Gyllenhammar AB as the parent company of Bronsstädet AB, which in turn holds approximately 79.5% of capital and votes in Duroc Aktiebolag (see Group structure, below). Swedish business media (Affärsvärlden) separately report that Duroc’s chairman, investor Peter Gyllenhammar, holds this position indirectly, citing the same 21,066,783 Class B shares and 9,933,217 Class C shares disclosed by Bronsstädet AB in Duroc’s own shareholder table. Because Peter Gyllenhammar AB’s own percentage ownership of Bronsstädet AB was not disclosed in the sources reviewed, an exact calculated effective percentage for Peter Gyllenhammar’s ultimate beneficial interest in Duroc Aktiebolag cannot be determined; it is reported here as an identified indirect controlling interest rather than a precise calculated percentage.
Data availability
Direct shareholder disclosure for Duroc Aktiebolag is major-shareholders-only: the company periodically publishes its largest shareholders (most recently as of 30 June 2026) but not a complete register of all shareholders, consistent with standard practice for a Nasdaq Stockholm-listed company. The ownership chain behind the largest shareholder is partial, since the percentage linking Peter Gyllenhammar AB to Bronsstädet AB was not found in the sources reviewed.

Directors and officers of Duroc Aktiebolag
Per Duroc AB’s own investor-relations pages, the company’s board of directors (styrelse) currently comprises three members: Peter Gyllenhammar (Chairman, appointed 2017), Carina Heilborn (Board member, appointed 2016) and Ola Hugoson (Board member, appointed 2017). Group management (ledning) is reported separately and comprises John Häger (Chief Executive Officer), Caroline Talsma (Chief Operating Officer) and Emil Otterskog (Chief Financial Officer). This reflects the board and management composition published on Duroc’s official website as of the retrieval date below and may differ from officer records held in other filing-based data sources, which can include historical or former appointees no longer serving.
Data availability
Sweden’s company register does not require public disclosure of directors’ nationality, so nationality is not disclosed for any of the individuals above and should not be inferred from name, residence or address. Duroc’s own website discloses each board member’s birth year and city of residence but not nationality or a separate correspondence address. Historical appointment and resignation dates for former officers were not independently verified in this research pass, so this overview should be treated as current-only rather than a complete history.

Group Structure
Group structure of Duroc Aktiebolag
Duroc Aktiebolag is not an independent, unaffiliated company. Duroc’s own shareholder disclosure identifies Bronsstädet AB as its majority shareholder, holding approximately 79.5% of capital and voting rights as of 30 June 2026, and Swedish company-registry sources record Bronsstädet AB as Duroc Aktiebolag’s immediate parent company. The same registry sources record Peter Gyllenhammar AB as the parent company of Bronsstädet AB, making Peter Gyllenhammar AB the identifiable ultimate parent in this ownership chain; the percentage of Bronsstädet AB held by Peter Gyllenhammar AB was not disclosed in the sources reviewed, so an exact indirect ownership percentage in Duroc Aktiebolag cannot be calculated. Duroc Aktiebolag itself operates as the holding company for a decentralised group of industrial and trading subsidiaries, described on its own website as comprising nine subsidiary companies organised around business areas including Duroc Machine Tool, Duroc Rail and a number of smaller industrial and trading holdings, with operations extending beyond Sweden into other European countries and the United States. Individual subsidiaries are already presented in this profile’s corporate-structure graph and are not repeated here.

Data availability
Corporate-linkage information for Duroc Aktiebolag is partial: the immediate and ultimate parent companies are identifiable from Duroc’s own shareholder disclosure and Swedish company-registry aggregator data, but the exact ownership percentage between Bronsstädet AB and Peter Gyllenhammar AB is not disclosed, and downstream subsidiaries are addressed separately in the profile’s corporate-structure graph rather than re-verified individually here.
