Bayer Aktiengesellschaft is a registered legal entity registered in Germany under HRB 48248 Köln, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Leverkusen, Germany. 3 shareholders are on record for Bayer Aktiengesellschaft, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Handelsregister (Commercial Register) and was last updated on 22 September 2026.

Shareholders

Shareholders of Bayer Aktiengesellschaft

Three shareholders are currently on record for Bayer Aktiengesellschaft, held on the Gesellschafterliste (shareholder list), filed under §40 of the GmbHG. The largest of these is NEW PERSPECTIVE FUND, holding 8.6% — the largest recorded stake — followed by iShares Trust-iShares MSCI EAFE ETF at 3.9%; the remaining 1 shareholder shown holds smaller stakes. Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Directors and officers of Bayer Aktiengesellschaft

Two of the 5 officer records shown for Bayer Aktiengesellschaft are current appointments, filed with Handelsregister (Commercial Register). Thomas Hoffmann (appointed 2019-09-18) and Konstanze Diefenbach (appointed 2022-03-22) both serve as Officer. The remaining 3 records shown (Michael Müller, Thomas Fritzsch and 1 other) are former appointments that have since been resigned. Management authority at Bayer Aktiengesellschaft sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control. The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.

Data availability

The register reports 467 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Group Structure

Group structure of Bayer Aktiengesellschaft

Bayer Aktiengesellschaft has no recorded parent company — it sits at the top of its own group structure, with 98 subsidiaries recorded beneath it across 49 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.

  • Bluerock Therapeutics LP (United States)
  • Bayer Consumer Care Holdings LLC (United States)
  • Erste K-W-A Beteiligungsges. mbH (Germany)
  • Bayer Cropscience Gmbh (Chile)
  • MONSANTO AGRICULTURE NIGERIA LIMITED (Nigeria)
  • AVENTIS CROPSCIENCE MALAWI LTD. (Malawi)
  • BAYER MIDDLE EAST FZE (United Arab Emirates)
  • Bayer (Schweiz) AG (Switzerland)
  • Semillas, S.A. (Guatemala)
  • AGREVO TANZANIA LTD. (Tanzania)

Data availability

Those 98 subsidiaries span Germany, United States, Chile, Nigeria, Malawi, United Arab Emirates, and 43 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. 26 of the 98 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
