BRUKER CORPORATION

Bruker Corporation is a public company on the Nasdaq Global Select Market, so its shareholder base is disclosed through beneficial-ownership filings with the U.S. Securities and Exchange Commission rather than published as a complete shareholder register. Based on the company’s definitive proxy statement for its 2026 annual meeting (record date 1 April 2026, with 152,223,137 shares of common stock outstanding), the largest disclosed institutional holders were FMR LLC (17,082,320 shares, 11.2%), Orbis Investment Management Ltd (15,197,866 shares, 10.0%) and BlackRock, Inc. (9,822,776 shares, 6.5%). These are aggregate reportable positions across each investor’s affiliated funds and accounts, not single registered shareholders of record, and the underlying holdings may have changed since the filing date.

Ultimate beneficial ownership

The largest individual beneficial owner on record is Frank H. Laukien, Bruker Corporation’s Chairman, President and Chief Executive Officer, who beneficially owned 40,510,066 shares (26.6% of common stock) as of 1 April 2026. This figure includes options exercisable within 60 days and shares held by family members over whom he is reported to exercise voting influence, although he disclaims beneficial ownership of those family holdings. The interest is held directly and personally rather than through a disclosed intermediate holding company, so no further ownership chain applies above this level.

Data availability

Availability here is best described as major shareholders only: SEC rules require only holders of 5% or more of the company’s stock, together with directors and executive officers, to report beneficial ownership, so the full base of smaller institutional and retail shareholders is not itemised publicly. Percentages reflect each filer’s most recently reported position and are not necessarily contemporaneous with one another.

Bruker Corporation discloses its current executive officers through SEC filings and investor-relations materials. Separately, each U.S. state in which the company is registered to do business collects its own officer listing as part of routine corporate filings, which is why registry data can show a large number of officer records for a single company across many states. Based on the company’s own disclosures, Frank H. Laukien is Chairman, President and Chief Executive Officer, a role he has held since Bruker’s founding era in the early 1990s. Gerald N. Herman has served as Executive Vice President and Chief Financial Officer since June 2018, having joined the company in 2016 as Vice President and Corporate Controller. Patrick Minhorst is recorded as the company’s Treasurer in state corporate filings, including with the Nevada Secretary of State, and separately holds the role of Vice President of Finance within the company’s Bruker BioSpin business.

Additional names appear in state-level officer filings for the company beyond this verified set; their current roles and appointment dates could not be independently corroborated against a primary source within this review and are therefore not described here.

Data availability

U.S. state corporate registries generally record officers as of the company’s most recent annual or franchise-tax filing rather than in real time, and do not disclose nationality or country of residence for corporate officers. The company’s own SEC filings and proxy statements are the more current and complete source for its senior executive team.

Bruker Corporation is a publicly traded Delaware corporation and, per its own SEC filings, has no parent company; it is the ultimate parent of the wider Bruker corporate group. The group is organised around four reporting segments (BSI BioSpin, BSI CALID, BSI NANO and Bruker Energy & Supercon Technologies) and operates through numerous subsidiaries across North America, Europe and Asia. One long-standing, independently verifiable subsidiary is Bruker BioSpin Corporation (Massachusetts), which became part of the group when Bruker Corporation and Bruker BioSpin combined under common ownership in a transaction that closed on 26 February 2008.

The company has continued to expand the group through acquisitions in recent years, including the ELITechGroup in-vitro diagnostics business (2024), an asset acquisition of the NanoString Technologies business completed 6 May 2024 for approximately 392.6 million US dollars (now operated within the company’s Spatial Biology unit), and Recipe Chemicals + Instruments GmbH (2025). These transactions are confirmed by the company’s own announcements and SEC filings, though this review did not independently re-verify the registration number, exact ownership percentage or current legal status of every operating entity that these acquisitions brought into the group.

Verified corporate relationships

Data availability

Group-structure information for Bruker Corporation is partial: the company confirms it has no parent, and its major, publicly announced subsidiaries and acquisitions are traceable through SEC filings and company announcements. However, Bruker Corporation does not publish a complete, ownership-percentage-by-entity subsidiary register, and the fuller list of smaller operating subsidiaries that can appear in third-party corporate-linkage data was not independently re-verified against each country’s primary company registry within this review.
