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. has closed its previously announced non-brokered private placement financing, marking the third follow-on investment under the company's previously disclosed binding letter of intent (LOI) with EV Metals VII LLC dated Feb. 28, 2025.

In connection with the offering, the company issued an aggregate of 26,427,053 units to EV Metals, with each unit comprising one International Battery common share and one warrant to purchase one International Battery common share and was priced at eight U.S. cents per unit, for total gross proceeds of $2.0-million (U.S.), which is based on an issue price of 10.4 Canadian cents for aggregate gross proceeds of $2,735,200 (Canadian) using the Bank of Canada exchange rate of $1 (U.S.) to $1.3676 (Canadian) as of Feb. 5, 2026. Each warrant will entitle the holder to purchase one International Battery common share at a price of 14 Canadian cents per International Battery 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 (direct lithium extraction) technology.

In accordance with the LOI, International Battery paid Jacob Warnock a cash structuring fee equal to 5 per cent 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.

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