Outstanding Equity Awards at Fiscal 2025 Year-End

Bakkt Opco Holdings, LLC (“Opco”), previously maintained a profits interests plan (the “Opco Plan”), for the award of Opco Incentive Units, through Opco Management, to participants, and Opco Participation Units, directly to participants. Awards of Opco Incentive Units included awards of common incentive units and preferred incentive units, each intended to represent a “profits interests” for U.S. tax purposes and each corresponded to incentive units of Opco Management issued by Opco Management to participants. The purpose of the Opco Plan was to promote the interests of Opco by attracting and retaining key employees, directors, independent contractors or other service providers of Opco and to enable such individuals to acquire an equity interest in and participate in the long-term growth and financial success of Opco. The profits interests represented a membership interest in Opco and entitled the holder to receive distributions in Opco once a specified threshold equity value of Opco had been reached, in each case as provided in the Opco operating agreement. The preferred incentive units are also entitled to disproportionate distributions once the participant’s applicable threshold equity value has been reduced to zero in order to “catch-up” such participant’s total distributions to its pro rata share. In fiscal 2025, the Company granted RSUs pursuant to the 2021 Plan, the Options pursuant to the Option Program and the Naheta Inducement Grant pursuant to NYSE Listing Rule 303A.08 and without stockholder approval. The following table sets forth information regarding outstanding equity awards held by our named executive officers as of December 31, 2025. The market value of the RSUs, the Options and the RSUs and PSUs subject to the Naheta Inducement Grant was calculated based on the NYSE closing price of the Common Stock on December 31, 2025 (the last trading day in fiscal 2025) of $10.04.
