ELBM Electra Battery Materials Corporation

Electra Battery Materials Corporation (NASDAQ: ELBM; TSX-V: ELBM) (“Electra” or the “Company”) announces that effective at the close of business on December 31, 2024, the Company will effect a reverse share split (the “Reverse Split”) of its outstanding common share capital on the basis of four (4) pre-Reverse Split shares for every one (1) post-Reverse Split share. At the opening of markets on January 2, 2025, the common shares of the Company (“Common Shares”) will commence trading on a post-Reverse Split basis under the existing ticker symbol “ELBM” and the new CUSIP: CA28474P7065.

The Reverse Split is being undertaken to support the Company’s efforts to regain compliance with the minimum bid price requirement (“Minimum Bid Requirement”) of US$1.00 per share under Nasdaq Listing Rule 5550(a)(2) on The Nasdaq Stock Market LLC (“Nasdaq”). Additionally, the Company believes an increased Common Share price will allow it to attract certain individual and institutional investors who have minimum share price thresholds for equity investments, which thresholds preclude them from investing in ‘penny stocks’. The Reverse Split was approved by shareholders of the Company at the special meeting of shareholders held on December 20, 2024.

As of the date of this news release, the Company has 59,213,423 Common Shares issued and outstanding. Following the completion of the Reverse Split, the Company is expected to have approximately 14,803,355 Common Shares issued and outstanding. The exercise price and number of Common Shares issuable upon the exercise of the Company’s outstanding options, warrants and other convertible securities will also be proportionally adjusted upon completion of the Reverse Split. Any fractional Common Share resulting from the Reverse Split will be rounded to the nearest whole number.

A letter of transmittal will be mailed to registered shareholders once the Reverse Split has taken effect. The letter of transmittal contains instructions on how registered shareholders can exchange their share certificates evidencing their pre-Reverse Split shares for new share certificates representing the number of post-Reverse Split shares to which they are entitled.

Beneficial shareholders holding their Common Shares through a brokerage may be subject to different procedures for obtaining their post-Reverse Split shares. If shareholders have any questions in this regard, they are encouraged to contact their respective brokerage or intermediary.
