Bruker Corporation 2026 Incentive Compensation Plan

At the 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”) of Bruker Corporation (the “Company”), held on May 29, 2025, the Company’s stockholders approved the Bruker Corporation 2026 Incentive Compensation Plan (the “2026 Plan”), which was approved by the Company’s Board of Directors (the “Board”) on February 18, 2025, subject to stockholder approval. The 2026 Plan will be effective as of February 19, 2026 (the “Effective Date”), which will be the date immediately following the date on which the Bruker Corporation 2016 Incentive Compensation Plan (the “Prior Plan”) expires. Subject to adjustment as set forth in the 2026 Plan, the aggregate number of shares of common stock, $0.01 par value (the “Common Stock”) authorized for issuance or delivery pursuant to the 2026 Plan will not exceed 12,000,000 shares of Common Stock, which is comprised of:

In addition, shares of the Common Stock underlying any outstanding award granted under the Prior Plan or the 2026 Plan that, following the Effective Date, expires, or is terminated, cancelled, exchanged, surrendered or forfeited for any reason without issuance of such shares will again be available for awards under the 2026 Plan. The 2026 Plan replaces the Prior Plan, and no additional awards will be granted under the Prior Plan on or after the Effective Date.

The 2026 Plan, which will be administered by the Compensation Committee of the Board or another committee appointed by the Board to administer the 2026 Plan (the “Committee”), provides for grants of awards to non-employee directors, employees, and certain key advisors of the Company and its subsidiaries in the form of nonqualified and incentive options, stock awards, stock units, stock appreciation rights, cash-based awards, and other awards. It is not possible to determine specific amounts and types of awards that may be granted to eligible participants under the 2026 Plan because the grant and payment of such awards is subject to the discretion of the Committee. The 2026 Plan will terminate on May 28, 2035, unless terminated earlier pursuant to its terms.

The foregoing description of the 2026 Plan does not purport to be complete and is qualified in its entirety by reference to the full text of the 2026 Plan, a copy of which is filed herewith as Exhibit 10.1 and incorporated herein by reference.
