April 2024 Notes On April 12, 2024, the Company issued and sold to Yorkville and Lind Global Fund II LP (together with Yorkville, the “April 2024 Purchasers”), $8,000 aggregate principal amount of unsecured notes (the “April 2024 Notes”), pursuant to a securities purchase agreement, dated April 11, 2024 (the “April 2024 Purchase Agreement”), between the Company and each of the April 2024 Purchasers. The Company also issued to the April 2024 Purchasers, in proportion to the aggregate principal amount of April 2024 Notes issued to each April 2024 Purchaser, Warrants (the “April 2024 Warrants”) to purchase up to 615,385 Common Shares (the “April 2024 Warrants Shares”), which were equal to 25% of the aggregate principal amount of April 2024 Notes issued to the April 2024 Purchasers divided by the exercise price of $3.25, subject to any adjustment to give effect to any stock dividend, stock split or recapitalization. The April 2024 Warrants expire on April 12, 2027. Pursuant to the April 2024 Purchase Agreement, the April 2024 Purchasers advanced an aggregate of $6,935 to the Company in consideration of the issuance by the Company to the April 2024 Purchasers of $8,000 aggregate principal amount of the April 2024 Notes and April 2024 Warrants. Under the terms of the April 2024 Notes, subject to certain exceptions, on the first day of each calendar month, beginning on June 1, 2024 (excluding August 2024) (the “Payment Date”), the Company was required to repay a portion of the outstanding balance of all of the April 2024 Notes, on a pro-rata basis, in an amount equal to the sum of (i) $1,400 of principal (or the outstanding principal if less than such amount) in the aggregate among all of the outstanding Notes, plus (ii) 8.0% of the principal amount being paid (the “Payment Premium”), and (iii) accrued and unpaid interest, if any, as of the Payment Date. The Company was required to make payments on each Payment Date until the entire outstanding principal was repaid but did not have an obligation to make a payment on a Payment Date if certain equity conditions were satisfied. Subject to certain limitations contained within the April 2024 Notes, holders of the April 2024 Notes were entitled to convert the principal amount of, accrued and unpaid interest, if any, and any Payment Premium that has become due and payable on each April 2024 Note, from time to time over their term, into a number of Common Shares equal to the quotient of the amount being converted divided by a fixed conversion price of $2.75 per Common Share up to a maximum of 3,141,817 Common Shares (together with the April 2024 Warrant Shares, the “April 2024 Underlying Shares”). The terms of the April 2024 Notes restricted the conversion of the April 2024 Notes by a holder if such a conversion would have caused such holder to exceed certain ownership thresholds in the Company. The April 2024 Notes were the unsecured obligations of the Company and were originally scheduled to mature on December 31, 2024. The April 2024 Notes incurred a simple interest rate obligation of 0.0% per annum (which would have increased to 18.0% per annum upon the occurrence of an event of default). The April 2024 Notes were also redeemable at the Company’s option at any time and from time to time over their term at a redemption price equal to the principal amount being redeemed, plus the Payment Premium, plus accrued and unpaid interest, if any, as of the redemption date. The April 2024 Notes contained events of default customary for instruments of their type (with customer grace periods, as applicable) and provided that, upon the occurrence of an event of default arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding April 2024 Notes would become due and payable immediately without further action or notice. If any other type of event of default occurred and continued, then any holder could have declared all of its April 2024 Notes to be due and payable immediately. The April 2024 Purchase Agreement contained customary representations, warranties, conditions and indemnification obligations by each party. The representations, warranties and covenants contained in the April 2024 Purchase Agreement were made only for purposes of the April 2024 Purchase Agreement and as of specific dates, were solely for the benefit of the parties to such agreement and are subject to certain important limitations. The April 2024 Purchase Agreement also contained certain covenants that, among other things, limited NioCorp’s ability to use the proceeds from the April 2024 Purchase Agreement to repay related party debt or to enter into any variable rate transaction other than with Yorkville, subject to certain exceptions, and to distribute proceeds from the April 2024 Purchase Agreement to subsidiaries other than ECRC and 0896800 B.C. Ltd. (together with ECRC, the “Guarantors”), upon the entry by the Guarantors into a global guaranty agreement, dated as of April 11, 2024, among the Guarantors in favor of the April 2024 Purchasers (the “Guaranty Agreement”). Pursuant to the Guaranty Agreement, the Guarantors guaranteed the full, prompt and unconditional payment when due (whether at maturity, by acceleration or otherwise), and the performance of all liabilities, agreements and other obligations of NioCorp to the April 2024 Purchasers contained in the April 2024 Notes, the April 2024 Warrants, and the April 2024 Purchase Agreement, to the extent such liabilities, agreements, and obligations are payable in cash. Based upon the Company’s analysis of the criteria contained in ASC 815, the Company determined that April 2024 Warrants met the definition of a derivative liability, as any Warrant exercise that could cause the holder to exceed 19.9% ownership of NioCorp Common Shares would require shareholder approval. As such, the April 2024 Warrants are recognized as Warrant liabilities on the consolidated balance sheet and were measured at their inception date fair value and are subsequently remeasured at each reporting period with changes being recorded as a non-operating gain or loss in the consolidated statement of operations and comprehensive loss. The Company elected to value the April 2024 Notes at fair value in accordance with ASC 815-15-25. The fair value of the April 2024 Notes was estimated using a Monte Carlo simulation pricing model and the April 2024 Notes were classified as Level 3 instruments. The Company incurred transaction costs totaling $474 in connection with the issuance of the April 2024 Notes and due to the fair value election noted above, these costs were expensed at closing. Components and initial valuations associated with the April 2024 Notes were comprised of the following amounts:
| ● | $902 was recorded to Warrant liabilities, representing the initial fair value of the April 2024 Warrants based on the assumptions outlined below.
| ● | $10,315 was recorded to the April 2024 Notes, representing the fair value based on the assumptions outlined below. The Company also recognized an opening transaction loss of $4,256, representing the difference between the fair value of the April 2024 Notes, including the fair value of the variable conversion features embedded therein, and cash received in the transaction.
