NioCorp Developments Ltd. is offering 17,400,000 Common Shares and, in lieu of shares to certain investors, 2,600,000 Pre-Funded Warrants on a "reasonable best efforts" basis.
The offering price per Common Share is $5.00, the Pre-Funded Warrants are priced at $4.9999 (exercise price $0.0001), and net proceeds to the company are estimated to be approximately $93.6 million after commissions and estimated offering expenses. Shares outstanding were 125,327,542 Common Shares as of February 23, 2026, and would be 142,727,542 Common Shares after this offering.
The proceeds are expected to be used for working capital and general corporate purposes, including advancing the Elk Creek Project toward commercial operation. The Pre-Funded Warrants will be immediately exercisable, have no expiration date, and are not expected to trade on any national exchange.
NioCorp Developments Ltd. is offering Common Shares and pre-funded Warrants to purchase Common Shares in a primary offering under a shelf registration statement.
The pre-funded Warrants have an exercise price of $0.0001 and are immediately exercisable with no expiration date. The Company reported 125,327,542 Common Shares outstanding as of February 23, 2026 and a last reported sale price of $5.55 per Common Share on February 23, 2026. The securities are being offered on a "reasonable best efforts" basis through Maxim Group LLC as sole placement agent, and the placement agent fee is disclosed as 6.00% of aggregate proceeds.
NioCorp Developments Ltd. is registering up to 4,250,000 common shares for resale by YA II PN, Ltd. (“YA”). These shares are “Advance Shares” that may be issued to YA under a Standby Equity Purchase Agreement under which NioCorp can sell up to $65.0 million of stock to YA during a defined commitment period, with about $25.3 million remaining as of January 16, 2026. NioCorp will not receive any proceeds from YA’s resale of these 4,250,000 shares; cash to the company would only come from future primary sales of shares to YA at a price equal to 97% of the daily VWAP. The filing highlights that these resales could pressure NioCorp’s share price and dilute existing holders. NioCorp is developing the Elk Creek Project in Nebraska, focused on niobium, scandium, titanium and rare earth elements, and may use any proceeds from future advances to fund project construction and general corporate purposes.
NioCorp Developments Ltd. (NB) launched a preliminary prospectus supplement for a primary offering of common shares and, in lieu of shares for certain investors, pre-funded warrants. The deal is on a “reasonable best efforts” basis via Maxim Group LLC, and the company—not the placement agent—will receive the proceeds, after commissions and expenses.
Each pre-funded warrant is immediately exercisable, carries no expiration, and has a $0.0001 per-share exercise price. The supplement also covers the common shares issuable upon warrant exercise. NioCorp plans to use net proceeds for working capital and to advance construction and commercialization efforts at its Elk Creek Project.
The company highlights risks typical of such offerings, including potential share price volatility, dilution, PFIC considerations, and the absence of an offering minimum or escrow under a best-efforts placement. Common shares trade on Nasdaq under “NB”; the pre-funded warrants will not be listed. As of October 10, 2025, shares outstanding were 101,993,495, and the last reported sale price was $10.39.
