The Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. Holders of The Public Warrants can exercise 25 Public Warrants to purchase one share of Class A Common Stock at an exercise price of $287.50 per share. The Public Warrants became exercisable on November 15, 2021. The Public Warrants will expire on October 15, 2026, or earlier upon redemption or liquidation. Bakkt may redeem the outstanding warrants when various conditions are met, such as specific stock prices, as detailed in the specific warrant agreements. The warrants are recorded as a liability and reflected as “Warrant liability” in the consolidated balance sheets. During the three months ended March 31, 2025 and March 31, 2024, the Company received an immaterial amount of proceeds from the exercise of the Public Warrants. Bakkt recognized a gain from the change in fair value of the warrant liability during the three months ended March 31, 2025 of $2.6 million and a loss during the three months ended March 31, 2024 of $1.0 million. In connection with the Concurrent Offerings (as defined below), Bakkt issued and sold to the Third-Party Purchasers (as defined below) an aggregate of 1,396,701 shares of the Company’s Class A Common Stock, including 196,701 shares of Class A Common Stock issued upon exercise of certain of the Pre-Funded Warrants (as defined below) prior to the Third-Party Closing, Class 1 Warrants (“Class 1 Warrants”) to purchase an aggregate of 922,722 shares of Class A Common Stock, Class 2 Warrants (“Class 2 Warrants”) to purchase an aggregate of 922,722 shares of Class A Common Stock and Pre-Funded Warrants (“Pre-Funded Warrants”) to purchase an aggregate of 448,742 shares of Class A Common Stock. Concurrently, under the terms of the ICE Offering (as defined below) the Company entered into a securities purchase agreement (the “ICE Purchase Agreement” and, together with the Third-Party Purchase Agreement, the “Purchase Agreements”) with ICE, pursuant to which Bakkt issued and sold to ICE an aggregate of 461,361 shares of Class A Common Stock, Class 1 Warrants to purchase an aggregate of 230,680 shares of Class A Common Stock, and Class 2 Warrants to purchase an aggregate of 230,680 shares of Class A Common Stock. The consummation of the transactions contemplated by the ICE Purchase Agreement occurred on March 4, 2024 and April 25, 2024. The Class 1 and Class 2 Warrants each have an exercise price of $25.50 and have a five-and-a-half year term. The Class 1 and Class 2 Warrants may each be exercised at any time after the 6 month anniversary of the relevant closing. The Class 2 warrant agreement contains an alternative exercise clause that entitles the holder to exchange two warrants for a share of stock if certain conditions are met. The Class 1 and Class 2 Warrants issued in the Concurrent Offerings are initially recorded as a liability at fair value and reflected as “Warrant liability” in the consolidated balance sheets. The Class 1 Warrants and Class 2 Warrants issued on April 25, 2024 were valued at $2.6 million using the Black-Scholes-Merton model for Class 1 Warrants and a binomial lattice model for the Class 2 Warrants. Prior to the second quarter of 2024, the Company used a Monte Carlo simulation to measure the fair value of the Class 2 Warrants. During the second quarter of 2024, management adopted a binomial lattice model as the valuation technique as management believes it provides a more accurate and relevant measure of the fair value of the Class 2 Warrants. The Class 1 Warrants and Class 2 Warrants issued on March 4, 2024 were valued at $27.7 million using the Black-Scholes-Merton model for Class 1 Warrants and a Monte Carlo simulation for the Class 2 Warrants.
