Each whole deSPAC Warrant entitles the registered holder to purchase one sixth of a share of the Company's Common Stock at a price of $11.50 per warrant, subject to adjustment as discussed below, at any time commencing on January 20, 2022, provided that the Company has an effective registration statement under the Securities Act of 1933, as amended (the "Securities Act") covering the shares of Common Stock issuable upon exercise of the deSPAC Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their deSPAC Warrants on a cashless basis under the circumstances specified in the warrant agreement (the "deSPAC Warrant Agreement") entered into between Continental Stock Transfer & Trust Company and Rotor and such shares are registered, qualified or exempt from registration under the securities laws of the state of residence of the holder. Pursuant to the deSPAC Warrant Agreement, a deSPAC Warrant holder may exercise its deSPAC Warrants only for a whole number of shares of the Company's Common Stock. The deSPAC Warrants will expire five years after the completion of the Business Combination, or September 24, 2026, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation. As of December 31, 2025, there were 20,549,453 deSPAC Warrants outstanding. The Company will not be obligated to deliver any Common Stock pursuant to the exercise of a deSPAC Warrant and will have no obligation to settle such deSPAC Warrant exercise unless a registration statement under the Securities Act with respect to the shares of Common Stock underlying the deSPAC Warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations described below with respect to registration, or a valid exemption from registration is available. No deSPAC Warrant will be exercisable, and the Company will not be obligated to issue a share of Common Stock upon exercise of a deSPAC Warrant unless the share of the Company's Common Stock issuable upon such deSPAC Warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the deSPAC Warrants. If the conditions in the two immediately preceding sentences are not satisfied with respect to a deSPAC Warrant, the holder of such deSPAC Warrant will not be entitled to exercise such deSPAC Warrant and such deSPAC Warrant may have no value and expire worthless. In no event will the Company be required to net cash settle any deSPAC Warrant. In the event a registration statement is not effective for the exercised deSPAC Warrants, the purchaser in the Rotor IPO of a Unit containing such deSPAC Warrant will have paid the full purchase price for the Unit solely for the share of the Company's Common Stock underlying such Unit. Except as described herein, the deSPAC Private Placement Warrants have terms and provisions that are identical to those of the deSPAC Public Warrants. If the deSPAC Private Placement Warrants are held by holders other than the initial purchasers or their permitted transferees, the deSPAC Private Placement Warrants will be redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the deSPAC Public Warrants. The deSPAC Private Placement Warrants will not be redeemable by the Company so long as they are held by the initial purchasers or their permitted transferees, subject to certain exceptions. The initial purchasers or their permitted transferees, have the option to exercise the deSPAC Private Placement Warrants on a cashless basis. Redemption of deSPAC Warrants When the Price per Share of the Company's Common Stock Equals or Exceeds $108.00. Once the deSPAC Warrants become exercisable, the Company may call the deSPAC Warrants for redemption: • in whole and not in part; • at a price of $0.01 per deSPAC Warrant; • upon not less than 30 days' prior written notice of redemption (the "30-day redemption period") to each deSPAC Warrant holder; and • if, and only if, the last reported sale price of the shares of the Company's Common Stock for any 20 trading days within a 30-trading day period commencing after the deSPAC Warrants become exercisable and ending three business days before the Company sends the notice of redemption to the deSPAC Warrant holders (which is referred to as the "Reference Value") equals or exceeds $108.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like). If and when the deSPAC Warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. However, the Company will not redeem the deSPAC Warrants unless an effective registration statement under the Securities Act covering the shares of the Company's Common Stock issuable upon exercise of the deSPAC Warrants is effective and a current prospectus relating to those shares of the Company's Common Stock is available throughout the 30-day redemption period. Redemption of deSPAC Warrants When the Price per Share of Our Common Stock Equals or Exceeds $60.00. Once the deSPAC Warrants become exercisable, the Company may redeem the outstanding deSPAC Warrants (except as described herein with respect to the deSPAC Private Placement Warrants if the Company does not utilize this redemption provision): • in whole and not in part; • at $0.10 per deSPAC Warrant upon a minimum of 30 days' prior written notice of redemption; provided that holders will be able to exercise their deSPAC Warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to an agreed table based on the redemption date and the "fair market value" of the Company's Common Stock; • if, and only if, the Reference Value (as defined above) equals or exceeds $60.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like); and • if the Reference Value is less than $108.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) the deSPAC Private Placement Warrants must also be concurrently called for redemption on the same terms (except as described above with respect to a holder's ability to cashless exercise its deSPAC Warrants) as the outstanding deSPAC Public Warrants, as described above. Both the deSPAC Public Warrants and the deSPAC Private Placement Warrants are recorded as warrant liabilities on the Company's consolidated balance sheets. The Company values both the deSPAC Public and deSPAC Private Placement Warrants using the closing price of the deSPAC Public Warrants on the Nasdaq Global Market as of the reporting date. The fair value measurement for the deSPAC Public Warrants is considered a level 1 fair value measurement, and the fair value measurement for the deSPAC Private Placement Warrants is considered a level 2 fair value measurement, as the deSPAC Private Placement Warrants are substantially the same, but not identical to, the deSPAC Public Warrants. The Company recognized gains of $14.5 million and losses of $15.7 million related to the change in fair value of the deSPAC Warrants during the years ended December 31, 2025 and 2024, respectively. These amounts are recorded as gain (loss) on warrant liabilities within the consolidated statements of operations.
