The Company’s registration statement on Form S-1 has been declared effective which highlights progress toward U.S. public market readiness

VANCOUVER, British Columbia & HOUSTON--(BUSINESS WIRE)--Feb. 2, 2026-- International Battery Metals Ltd. (“IBAT”) (TSXV: IBAT) & (OTCQB: IBATF), an advanced technology provider of modular direct lithium extraction (DLE) systems, today provided an update on its U.S. securities reporting status, including that the Company’s registration statement on Form S-1 has been declared effective by the U.S. Securities and Exchange Commission (“SEC”).

Joseph Mills, Chief Executive Officer of IBAT, commented:

“The SEC’s declaration of effectiveness of our registration statement on Form S-1 represents an important milestone and reinforces our longer-term objective to pursue a listing on a U.S. national exchange at the appropriate time. In that context, maintaining an effective SEC registration statement and operating within a defined U.S. reporting framework reflects progress toward aligning IBAT with public market standards expected by institutional and retail investors alike. While these actions do not alter our operational fundamentals, they enhance transparency, reduce regulatory uncertainty and strengthen the foundation for future capital markets engagement.”

The registration statement relates to the resale, from time to time, of securities previously issued in private placements. The Company is not offering or selling any securities under the registration statement and will not receive any proceeds from the resale of securities by selling shareholders. The Company may receive proceeds only in the event that warrants are exercised for cash, if any.

With the Company now operating within an SEC reporting framework, IBAT expects to continue strengthening its disclosure practices and investor communications. Management believes this framework supports clearer, more consistent information flow, broader engagement with U.S. investors and improved long-term capital markets readiness.

The Company emphasizes that the SEC’s declaration of effectiveness does not constitute approval or endorsement of the Company or its securities.
