NioCorp Developments Ltd. reported results from its April 6, 2026 annual meeting, where shareholders approved an amended and restated shareholder rights plan and an updated long-term incentive plan.
The amended rights plan now runs until the company’s 2027 annual general meeting, unless earlier redeemed or terminated by the board and subject to no Flip-In Event occurring. This extends the company’s protective framework against certain concentrated share accumulations.
Shareholders also approved the 2017 Amended Long-Term Incentive Plan, which replaces a prior “evergreen” structure with a fixed pool of up to 11,300,000 common shares for options, share units and dividend equivalents, subject to specified share-counting and adjustment rules. All six director nominees were elected, Deloitte & Touche LLP was reappointed as auditor, executive compensation received majority advisory support, and the amendments to both the incentive plan and rights plan were approved.
NioCorp Developments Ltd. is asking shareholders to approve several items at its April 6, 2026 annual meeting, including director elections, auditor ratification, an advisory say-on-pay vote, and a major amendment to its long-term incentive plan.
The amended plan would authorize awards covering up to 11,300,000 common shares, about 9% of shares outstanding, bringing total equity overhang from option and incentive plans to roughly 16,152,500 shares, or 12.9% of outstanding shares as of February 9, 2026. Management argues equity awards are critical to attracting and retaining key talent and aligning pay with performance.
The proxy also highlights operational progress in 2025 at the Elk Creek Project, including over $370 million in gross financing, $10 million of U.S. federal support, a potential Export-Import Bank debt package of up to $800 million, and a year-end cash balance of about $307 million with no debt, which the company believes improve its financial position heading into 2026.
NioCorp Developments Ltd. completed a U.S. public offering of 20,000,000 common shares (or pre-funded warrants in lieu thereof) at $5.00 per share (or $4.9999 per pre-funded warrant), generating gross proceeds of approximately $100.0 million and net proceeds of about $93.6 million after fees and expenses.
The deal was conducted on a reasonable best-efforts basis with Maxim Group LLC as exclusive placement agent and closed on February 25, 2026. It included 17,400,000 common shares and 2,600,000 pre-funded warrants, each warrant exercisable for one common share at $0.0001 with no expiry and a 4.99% or, upon notice, 9.99% beneficial ownership cap. Company executives and directors agreed to a 30‑day lock-up on sales, and the company agreed to 60‑day restrictions on most new equity issuances and price-reset securities.
NioCorp currently intends to use the net proceeds for working capital and general corporate purposes, including advancing its Elk Creek critical minerals project in Southeast Nebraska toward commercial operation.

For the six months ended December 31, 2025, net loss attributable to the company was $43,282, driven mainly by higher exploration spending of $11,716 and non-cash fair value charges on earnout and warrant liabilities totaling more than $26,000.
