EXPLANATORY NOTE

This Current Report on Form 8-K/A (this “Amendment”) is being filed solely to replace the version of Exhibit 5.1 (the “Initial Exhibit”) attached to the Company’s Current Report on Form 8-K filed with the SEC on May 31, 2024 (the “Initial 8-K”) and amends and restates the Initial 8-K in its entirety. Due to a clerical error, the Initial Exhibit inadvertently excluded the number of Shares (as defined below) issued and sold in the Offering (as defined below) as described in Item 1.01 of the Initial 8-K. Except for the foregoing, this Amendment does not modify or update any disclosure contained in the Initial 8-K or its other exhibits, and such other exhibits thereto (other than Exhibit 23.1, which is included in Exhibit 5.1 filed herewith) are hereby expressly incorporated into this Amendment by reference.

On May 29, 2024, Bruker Corporation (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with BofA Securities, Inc. and J.P. Morgan Securities LLC (the “Underwriters”), relating to an underwritten public offering (the “Offering”) of 6,000,000 shares (the “Firm Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”). The Underwriters agreed to purchase the Common Stock pursuant to the Underwriting Agreement at a price to the Underwriters of $67.29 per share (the “offering price”). Pursuant to the Underwriting Agreement, the Company also has granted the Underwriters the right to purchase from the Company up to an additional 900,000 shares of Common Stock (the “Option Shares” and, together with the Firm Shares, the “Shares”), exercisable within a 30-day period, at the offering price.

The Offering was made pursuant to an automatically effective registration statement on Form S-3 filed with the Securities and Exchange Commission (the “SEC”) on May 29, 2024 (File No. 333-279783) and a final prospectus relating to the Offering, filed with the SEC on May 31, 2024.

The Underwriting Agreement contains customary representations, warranties and covenants of the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties, and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates and were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by such parties. The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the Underwriting Agreement, a copy of which is attached as Exhibit 1.1 hereto and is incorporated by reference herein.

A copy of the legal opinion, including the related consent, of Morgan, Lewis & Bockius LLP relating to the legality of the issuance and sale of the Shares in the Offering is filed as Exhibit 5.1 to this Current Report on Form 8-K.

On May 29, 2024, the Company issued press releases announcing that it had launched and priced the Offering. Copies of the press releases are attached as Exhibits 99.1 and 99.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
