This would be better left to Scooter.
But with a glace I see you missed note 1 with regard to Yorkville:
(1) Beneficial ownership includes (a) an estimated 5,035,293 Common Shares issuable upon conversion of the Convertible Debentures, assuming (i) the conversion of all $10,000,000 aggregate principal amount outstanding of the Convertible Debentures, plus $793,151 of accrued interest, (ii) a conversion price equal to the Floor Price (as defined herein) of $2.1435 and (iii) none of the limitations on conversion of the Convertible Debentures set forth in the Yorkville Convertible Debt Financing Agreement apply; and (b) 1,789,267 Common Shares issuable upon exercise of the Financing Warrants, assuming (i) none of the holders of the Financing Warrants elects cashless exercise and (ii) none of the limitations on exercise of the Financing Warrants set forth the Yorkville Convertible Debt Financing Agreement apply. Pursuant to the terms of the Convertible Debentures and the Financing Warrants, YA may not convert Convertible Debentures or exercise Financing Warrants into Common Shares in an amount that would result in YA (or its affiliates) beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) more than 4.99% of the Common Shares outstanding immediately after giving effect to such conversion or exercise or receipt of shares (the “Beneficial Ownership Limitation”); provided that YA may waive the Beneficial Ownership Limitation upon not less than 65 days’ prior notice to NioCorp. In accordance with Rule 13d-3(d) under the Exchange Act, we have excluded from the number of Common Shares beneficially owned prior to the offering all of the Common Shares that YA may be required to purchase under the Yorkville Equity Facility Financing Agreement, because the issuance of such Common Shares is solely at our discretion and is subject to conditions contained in the Yorkville Equity Facility Financing Agreement, the satisfaction of which are entirely outside of YA’s control. YA is a fund managed by Yorkville Advisors Global, LP. Yorkville Advisors Global II, LLC is the General Partner of Yorkville Advisors Global, LP. All investment decisions for YA are made by Yorkville Advisors Global II, LLC’s President and Managing Member, Mr. Mark Angelo.
