Before the Closing, Zanite had issued 11,500,000 redeemable warrants included in the units sold in the initial public offering (the "Public Warrants") and 14,250,000 redeemable warrants in private placements (the "Private Placement Warrants"). The exercise period of the Public and Private Placement Warrants started 30 days after the Closing and will terminate on the earlier of five years after the Closing date, the date fixed by the Company to redeem all of the warrants, or the liquidation of the Company.

Each Public Warrant entitles its holder to purchase one share of common stock at an exercise price of $11.50 per share, to be exercised only for a whole number of shares of our common stock. The Public Warrants became exercisable 30 days after the Closing (i.e., on June 8, 2022), provided that we have an effective registration statement under the Securities Act covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or we permit holders to exercise their warrants on a cashless basis under the circumstances specified in the warrant agreement) and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. The Public Warrants expire five years after the Closing or earlier upon redemption or liquidation. Once the Public Warrants become exercisable, we may redeem the outstanding Public Warrants at a price of $0.01 per warrant, if the last sale price of our common stock equals or exceeds $18.00 per share for any 20 trading days within a 30 trading days period ending on the third business day before the Company sends the notice of redemption to the warrant holders.

Upon the Closing, all shares of Zanite Class A and Class B common stock were converted into, on a one-for-one basis, shares of common stock of Eve. As such, in a hypothetical change-in-control scenario, all holders of the stock would receive cash. Additionally, the Public Warrants are indexed to the Company’s own stock. Thus, at the Closing, the Public Warrants valued at $10,580,000 were reclassified from liability to equity.

The Company has entered into warrant agreements with certain strategic private investment in public equity investors ("Strategic PIPE Investors"), including United, pursuant to which and subject to the terms and conditions of each applicable warrant agreement. The Company has issued or has agreed to issue to the Strategic PIPE Investors warrants (the "New Warrants") to purchase an aggregate amount of (i) 24,095,072 shares of common stock with an exercise price of $0.01 per share ("Penny Warrants"), (ii) 12,000,000 shares of common stock with an exercise price of $15.00 per share, and (iii) 5,000,000 shares of common stock with an exercise price of $11.50 per share. Warrants with exercise prices of $15.00 and $11.50 per share are defined as Market Warrants.

Because the cash received for the common stock and New Warrants is significantly different from their fair value, Management considers such warrants to have been issued other than at fair market value. Accordingly, such warrants represent units of account separate from the shares of common stock that were issued to the Strategic PIPE Investors in connection with their respective PIPE Investments and therefore require separate accounting treatment.

Terms related to the issuance and exercisability of the New Warrants differ among the Strategic PIPE Investors and each New Warrant is independently exercisable such that the exercise of any individual warrant does not depend on the exercise of another. As such, Management has concluded that all New Warrants meet the criteria to be legally detachable and separately exercisable and therefore freestanding.

(a) Potential lender/financier: Market Warrants were issued to potential lender/financier counterparties at Closing, vested immediately, and do not contain exercise contingencies. These warrants were determined to be within the scope of ASC 815, Derivatives and Hedging, and equity-classified. Fair value was measured at the issuance date and recognized as New Warrants expense. As long as these warrants continue to be classified as equity, subsequent fair value remeasurement is not required.

(b) Potential customers: Market and Penny Warrants issued or issuable to potential customers of Eve were determined to be within the scope of ASC 718, Compensation-Stock Compensation, for classification and measurement and ASC 606, Revenue from Contracts with Customers, for recognition. In accordance with ASC 718, these warrants were determined to be equity-classified. The Penny Warrants can be separated into two categories: (i) contingently issuable warrants (the “Contingent Warrants”) and (ii) warrants that immediately vested upon Closing (“Vested Warrants”). The Contingent Warrants are measured at fair value on the grant date and will be recognized as variable consideration (a reduction of revenue) under ASC 606 when and if there are related revenue transactions or as New Warrants expense if there are not yet related revenue transactions. The Vested Warrants were accounted for akin to a non-refundable upfront payment to a potential customer and were recognized as New Warrants expense as Eve has no current revenue or binding contracts in place. Market Warrants issued at Closing to potential customers vested immediately and have no contingencies.

(c) Potential suppliers: Penny Warrants issued or issuable to potential suppliers of Eve, which are subject to the satisfaction of certain specified conditions, are accounted for as non-employee awards under ASC 718 and were determined to be equity-classified. The fair value of these warrants will be recognized as expense as products and/or services are received from the suppliers as if Eve paid cash for the respective transactions.

The New Warrants were measured at fair value on the grant date (May 9, 2022), except for cases where there has been a modification, where fair value is remeasured on the modification date. The fair value of Penny Warrants were calculated by subtracting $0.01 from Eve’s share price on the grant date. Market Warrants with an exercise price of $11.50 were estimated using the publicly traded Public Warrants as the terms are similar. The Company used a modified Black-Scholes model to value the Market Warrants with an exercise price of $15.00. The valuation model utilizes management judgment and pricing inputs from observable and unobservable markets with less volume and transaction frequency than active markets. Significant deviations from these estimates and inputs could result in a material change in fair value.

Forfeitures of New Warrants within the scope of ASC 718, granted to non-employees, are estimated by the Company and reviewed when circumstances change.

Each Private Placement Warrant entitles its holder to purchase one share of common stock at an exercise price of $11.50 per share, subject to conditions as defined in the Warrant Agreement. The Private Placement Warrants have similar terms as the Public Warrants, except for the $0.01 cash redemption feature. However, in the event a Private Placement Warrant is transferred to a third-party not affiliated with the Sponsor (referred to as a non-permitted transferee), the warrant becomes a Public Warrant and is subject to the $0.01 cash redemption feature. If this occurs, the calculation changes for the settlement amount of the Private Placement Warrants. Since the settlement amount depends solely on who holds the instrument, which is not an input to the fair value of a fixed-for-fixed option or forward on equity shares, the Private Placement Warrants are classified as a liability.
