DEUTZ Aktiengesellschaft, the Cologne-based engine manufacturer listed under ISIN DE0006305006, has been the subject of a major shareholding notification filed under Article 40, Section 1 of the German Securities Trading Act (WpHG). The disclosure, dated 5 November 2026, reveals that four members of the Bischoff family — acting in concert through a chain of holding companies — have collectively reached a 29.90% voting stake in DEUTZ AG. The notification is the first of its kind from this group, with no previous position on record, making this a significant new disclosure for investors monitoring the company's shareholder register.

Key Points

  • DEUTZ Aktiengesellschaft (0E4K / ISIN DE0006305006), a German engine manufacturer headquartered in Köln (Porz-Eil)
  • The Bischoff family group disclosed a combined 29.90% indirect voting stake, crossing the threshold on 5 November 2026
  • The total voting rights held amount to 71,615,796 shares out of 239,517,711 total voting rights pursuant to Section 41 WpHG
  • Investors should watch for any further threshold crossings or changes to the voting rights agreement underpinning the concert party arrangement

Bischoff Family Acts in Concert Through BRIMA GmbH and Three Additional Holding Companies

The notification identifies four natural persons as subject to the disclosure obligation: Rainer Bischoff, Ingrid Bischoff, Marc-Aurel Bischoff, and Anna Bischoff. Their combined position is held indirectly through a chain of controlled entities, the primary vehicle being BRIMA GmbH Unternehmensberatung Unternehmensbeteiligungen ("BRIMA"), alongside J.O.S.S. Beteiligungsgesellschaft mbH, Universum Holding GmbH, and FFG Beteiligungsgesellschaft mbH. All 71,615,796 voting rights are classified as indirect holdings under Section 34 WpHG, meaning no shares are held directly by the notifying individuals themselves.

Voting Rights Agreement Attributes 53.7 Million Additional Shares to BRIMA Under WpHG Rules

The announcement provides additional structural detail relevant to understanding the concert party arrangement. BRIMA directly holds 17,903,949 voting rights in DEUTZ AG, attributed to the Bischoff notifiers under Section 34 WpHG. Crucially, a separate voting rights agreement means BRIMA is also attributed a further 53,711,847 voting rights held by the three other companies named in section 4 of the notification, pursuant to Section 34(2) WpHG. This voting rights agreement is the mechanism through which the acting-in-concert designation arises and through which the aggregate 29.90% position is calculated and disclosed.

29.90% Stake Represents First Recorded Position for This Group in DEUTZ AG

The filing notes that the previous notification field carries no prior percentage, confirming this is the first time the Bischoff family group has formally notified a position in DEUTZ AG at or above a statutory threshold under German securities law. DEUTZ AG, whose LEI code is 5299005DETTV58V2PP63, is a specialist manufacturer of drive systems, primarily diesel and alternative-fuel engines used across agricultural, construction, and industrial applications. The total voting rights figure of 239,517,711 is stated pursuant to Section 41 WpHG and forms the denominator for all percentage calculations in the disclosure.

Regulatory Context: WpHG Thresholds and European-Wide Distribution

The notification was transmitted via EQS News under Article 40, Section 1 of the WpHG, with the stated objective of Europe-wide distribution. Under German securities law, major shareholder notifications are required when voting rights cross defined thresholds, ensuring transparency for all market participants. The reasons cited in the filing include both acquisition or disposal of shares with voting rights and the acting-in-concert designation. No instruments such as options or convertibles are included in the position, as both Section 38(1) no. 1 and no. 2 WpHG instrument totals are recorded at zero.
