International Battery Metals Announces Closing of Previously Announced Third Follow-On Investment From EV Metals 9 LLC, Adding USD $2.0 Million Under Existing LOI

International Battery Metals Ltd . (“IBAT” or the “Company”) (TSXV: IBAT) & (OTCQB: IBATF), an advanced technology provider of modular direct lithium extraction (DLE) systems, today announced the closing of its previously announced non-brokered private placement financing (the “Offering”), marking the third follow-on investment under the Company’s previously disclosed binding Letter of Intent (“LOI”) with EV Metals VII LLC (“EV Metals”) dated February 28, 2025.

In connection with the Offering, the Company issued an aggregate of 26,427,053 units (the “Units”) to EV Metals, with each Unit being comprised of one IBAT common share and one warrant (each, a “Warrant”) to purchase one IBAT common share and was priced at USD $0.08 per Unit, for total gross proceeds of USD $2.0 million, which is based on an issue price of C$0.104 for aggregate gross proceeds of C$2,735,200 using the Bank of Canada exchange rate of US$1.00 to C$1.3676 as of February 5, 2026. Each Warrant will entitle the holder to purchase one IBAT common share at a price of C$0.14 per IBAT share for a period of four years from the date of issuance.

Proceeds from the Offering will be used for general corporate purposes as the Company continues to advance deployment of its next-generation modular DLE technology.

In accordance with the LOI, IBAT paid Jacob Warnock a cash structuring fee equal to 5% of the gross proceeds of the Units subscribed for by the EV Metals affiliates in connection with the Offering.

The Units will be subject to a four-month plus one-day hold period under Canadian securities laws and will be considered restricted securities under the U.S. Securities Act of 1933.

This press release does not constitute an offer to sell or the solicitation of an offer to buy any securities in any jurisdiction where such an offer or sale would be unlawful. The securities have not been, and will not be, registered under the U.S. Securities Act of 1933 and may not be offered or sold in the United States absent registration or an applicable exemption.

Separately, the Company and EV Metals have mutually agreed to extend the original LOI termination date to April 30, 2026.

IBAT is exempt from the formal valuation requirement in reliance on section 5.5(a) of MI 61-101 and from minority shareholder approval in reliance on section 5.7(1)(a) of MI 61-101, as the fair market value of the Offering and the structuring fee, insofar as it involves related parties, is not more than 25% of the Company's market capitalization.
