Company Update

Electra also wishes to provide an update on the proposed reverse split (the “Reverse Split”) of the issued and outstanding common shares (the “Common Shares”) of the Company. At the special meeting of shareholders of the Company held on October 15, 2025, shareholders approved the Reverse Split at a ratio of one (1) post-Reverse Split Common Share for up to three-and-a-half (3.5) pre-Reverse Split Common Shares, as may be determined by the board of directors of the Company (the “Board”) in its sole discretion, if at all. Electra has elected not to proceed with the Reverse Split at this time. Electra remains committed to strengthening its presence in the U.S. capital markets and is committed to the standards of transparency, governance, and financial discipline expected of a Nasdaq-listed issuer.

The Company will continue to monitor market conditions and regulatory requirements and may re-evaluate the split decision if circumstances warrant. The Board retains full discretion to effect the Reverse Split in the future should it determine that doing so is in the best interests of the Company and its shareholders. The Board continues to monitor relevant factors, including market dynamics, capital structure, and long-term objectives.

In accordance with the Company’s Long-Term Incentive Plan approved by shareholders at the annual general meeting on June 24, 2025, Electra has issued 2,669,000 incentive stock options (the “Options”), 179,000 restricted share units (“RSUs”), and 271,000 deferred share units (“DSUs”) to certain directors, officers, employees, and contractors.

These long-term incentive awards are a key element of Electra’s compensation strategy and are designed to retain and motivate high-performing personnel while aligning their interests with those of shareholders. The RSUs will vest in two equal tranches on the first and second anniversaries of the grant date and may be settled in cash or shares at the discretion of the Company. The DSUs will be settled in shares when the holder ceases to serve as a director. The Options are exercisable for three years at today’s closing price of C$1.97 and will vest in two equal tranches on the first and second anniversaries of the grant date. Completion of the incentive grants remains subject to the approval of the TSX Venture Exchange.
