CLASS B COMMON STOCK OF ECRC |
| 10. | CLASS B COMMON STOCK OF ECRC
Pursuant to the Business Combination Agreement, the Sponsor Support Agreement, and the Exchange Agreement, after the Closing, the GXII founders have the right to exchange shares of Class B common stock of ECRC for Common Shares on a one-for-one basis, subject to certain equitable adjustments, under certain conditions. All 7,957,404 shares of Class B common stock of ECRC that were issued in connection with the Closing were issued and outstanding as of June 30, 2023. Of the issued and outstanding shares of Class B common stock of ECRC, 4,565,808 shares (the “Vested Shares”) were vested as of the Closing Date and are exchangeable at any time, and from time to time, until the tenth anniversary of the Closing Date (the “Ten-Year Anniversary”) and 3,391,596 shares (the “Earnout Shares”) are exchangeable until the Ten-Year Anniversary, subject to certain vesting conditions. Under certain circumstances, and subject to certain exceptions, NioCorp may instead settle all or a portion of any exchange pursuant to the terms of the Exchange Agreement in cash, in lieu of Common Shares, based on a volume-weighted average price of Common Shares. On February 28, 2024 and May 16, 2024, 243,692 Vested Shares and 40,000 Vested Shares, respectively, were exchanged for an equivalent number of Common Shares. This exchange resulted in a change in the Company’s ownership interest in ECRC and was accounted for as an equity transaction in accordance with ASC 810-10-45-23, with no gain or loss recognized. Accordingly, the carrying amount of the noncontrolling interest was adjusted to reflect the change in the Company’s ownership interest with a corresponding offset booked to equity. All of the shares of Class B common stock of ECRC are subject to the Amended and Restated Registration Rights Agreement, dated as of March 17, 2023 (the “Registration Rights and Lock-up Agreement”), among NioCorp, GXII, the Sponsor, the pre-Closing directors and officers of NioCorp and the other parties thereto, including the members of the Sponsor. Pursuant to Registration Rights and Lock-up Agreement, all shares of Class B common Stock of ECRC (including the Vested Shares and the Released Earnout Shares) are subject to certain “lock-up” restrictions on transfer beginning upon the Closing and ending upon the earlier of (i) one year after the Closing and (ii) the date on which the trading price of Common Shares exceeds certain thresholds or the date on which NioCorp completes a transaction that results in all of NioCorp’s shareholders having the right to exchange their Common Shares for cash, securities or other property. Both Vested Shares and Released Earnout Shares may be exchanged by the holders into Common Shares at any time. Under the Exchange Agreement, all Vested Shares and Earnout Shares must be exchanged for Common Shares by the Ten-Year Anniversary except for Released Earnout Shares that have been vested for a period of fewer than twenty-four months as of the Ten-Year Anniversary. Such Released Earnout Shares will be forfeited if not exchanged for Common Shares by the date that is twenty-four months after the vesting date. Vested Shares As the exchange of Vested Shares are contingently redeemable at the option of the noncontrolling interest shareholders, the Company classifies the carrying amount of the redeemable noncontrolling interest in the mezzanine section on the consolidated balance sheet, which is presented above the equity section and below liabilities. Adjustments to the carrying value of the redeemable noncontrolling interest associated with redemptions are recorded by reclassifying the proportionate amount of mezzanine equity to permanent equity. Earnout Shares The Earnout Shares vest (the “Released Earnout Shares”) in two equal tranches based upon achieving market share price milestones of approximately $12.00 per Common Share and approximately $15.00 per Common Share, respectively, prior to the Ten-Year Anniversary, or upon a change in control as defined in the underlying agreement. These shares will be forfeited if the market share price milestones or an acceleration event is not reached prior to the Ten-Year Anniversary. At such time that the Earnout Shares shall become vested, and therefore, become Released Earnout Shares, the shares will be transferred to the redeemable noncontrolling interest in the mezzanine section of the Consolidated Balance Sheet. The Earnout Shares were classified as a liability due to failure to meet the equity classification criteria under ASC 815-40, as Level 3 instruments under the fair value hierarchy and are considered a financial liability under ASC 480, Distinguishing Liabilities from Equity. The Earnout Shares were measured at fair value on the Closing Date with subsequent changes in fair value recorded in earnings. The Earnout Shares were valued utilizing a Monte Carlo simulation pricing model. The following table discloses the primary inputs into the Monte Carlo models.
