Item 1.01 Entry Into a Material Definitive Agreement.

On April 29, 2026, International Battery Metals LTD (the "Company") entered into a Subscription Agreement and executed a Warrant Certificate with respect to the Offering described in Item 3.02 below. The information contained in Item 3.02 of this Current Report on Form 8-K in relation to the Common Shares and the Warrants is incorporated herein by reference.

Item 3.02 Unregistered Sale of Equity Securities.

On April 29, 2026, the Company issued 34,315,465 Units (the “Units”) to EV Metals 9 LLC ("EV Metals"), an affiliate of EV Metals 7 LLC, pursuant to its previously announced non-brokered private placement financing (the "Offering"). The offer is the fourth follow-on investment under the Company's previously announced binding Letter of Intent ("LOI") with EV Metals 7 LLC from March 2025.

Each Unit includes one Company common share and one warrant (each, a "Warrant") to purchase one common share and is priced at USD $0.08 per Unit, with total gross proceeds of USD $2.8 million. Each Warrant entitles the holder to purchase one additional Company common share at a price of C$0.148 per share for a period of four years from the date of issuance.

In accordance with the LOI, IBAT paid Jacob Warnock a structuring fee equal to 5% of the gross proceeds subscribed for by EV Metals affiliates in connection with the Offering, in cash at closing. The Units are subject to a four-month plus one-day hold period under Canadian securities laws and will be considered restricted securities under the Securities Act.

The sale of the Units issued in the Offering were issued in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended.

EV Metals is controlled by a director of the Company, Jacob Warnock.
