ROCK TECH LITHIUM ANNOUNCES PLANS TO DUAL-LIST ON NASDAQ AND FILING OF SHORT FORM BASE SHELF PROSPECTUS

Rock Tech Lithium Inc. has filed a preliminary short form base shelf prospectus and annual information form with the securities regulators in each of the provinces and territories of Canada. These filings represent a significant and deliberate step in the company's strategic road map -- which the company expects may be used, subject to receipt and regulatory approvals, in connection with a potential Nasdaq dual listing through the multijurisdictional disclosure system, the established bilateral framework between Canadian and U.S. capital market regulators.

Nasdaq dual listing readiness through MJDS

Under the MJDS framework, eligible Canadian issuers may file a U.S. registration statement with the U.S. Securities and Exchange Commission on Form F-10, which is primarily based on Canadian disclosure documents, including the company's base shelf prospectus. This bilateral system substantially reduces regulatory duplication, cost and processing time, which may streamline the disclosure process for a Nasdaq cross-listing, subject to SEC effectiveness and Nasdaq approval. Rock Tech's existing TSX Venture Exchange listing, combined with its 12-month-plus Canadian reporting history and qualifying public float, positions the company as MJDS eligible. The Nasdaq filing remains subject to Nasdaq approval.

25-month capital flexibility window

The final base shelf prospectus, if receipted, will be valid for a period of 25 months from the date of receipt. During this window, Rock Tech retains the option to access capital markets from time to time and in tranches aligned with project milestones -- without requiring a full regulatory review for each potential future offering. This significantly reduces execution risk and cost in time-sensitive financing situations.

Institutional credibility and market profile

A filed base shelf prospectus is commonly used by more established TSX Venture Exchange-listed issuers, and is intended to support corporate governance practices, capital market readiness and financing flexibility. It is standard practice among established TSX-V-listed resource and technology companies operating at Rock Tech's scale. The filing reinforces Rock Tech's positioning as a strategic, investment-ready critical mineral platform.

"This filing is about building institutional-grade capital markets infrastructure for tomorrow. Filing our shelf prospectus is an important step in preparing for a potential Nasdaq dual listing via the MJDS process. A Nasdaq listing, if achieved, is a transformative rerating event for Rock Tech. It opens our story to the full depth of the North American institutional investor base at exactly the moment our project pipeline -- Guben, Red Rock, Georgia Lake -- is entering its most consequential phase," says Rock Tech's chief executive officer, Mirco Wojnarowicz.

Rock Tech is advancing toward a Nasdaq dual listing as a cornerstone of its institutional investor strategy. With the Guben converter holding European Union CRMA strategic project status and a full permit and engineering package, the Red Rock converter project in Ontario, Canada, carrying a $2.3-billion net present value and a committed capital structure under the GP/LP framework, and the Georgia Lake mine in Ontario positioned to create North America's first fully integrated mine-to-battery-grade lithium supply chain, Rock Tech believes the Nasdaq listing, if completed, could serve as a significant rerating catalyst -- expanding visibility, research coverage and shareholder liquidity across the world's deepest capital market.

About Rock Tech Lithium Inc.

Rock Tech is enabling the battery age by making the battery industries in Europe and North America more independent and competitive. The company's goal is to ensure the supply of high-quality, locally produced lithium -- supporting a resilient, sustainable and transparent value chain from mine to battery-grade material.

Rock Tech relies on responsible sourcing, state-of-the-art and proven technologies and a clear focus on circular economy principles. The company's lithium converter projects in Guben, Germany (24,000 tonnes lithium hydroxide monohydrate per year), and Ontario, Canada (up to 32,000 tonnes lithium carbonate equivalent per year), form the foundation for a stable and regional supply to the battery and automotive industries. The Guben converter has been recognized as a strategic project under the EU Critical Raw Materials Act.

The raw materials for Rock Tech's converter projects are sourced exclusively from verifiably environmental, social and governance compliant suppliers. In Canada, Rock Tech relies, among other sources, on its wholly owned Georgia Lake project, which ensures a stable and sustainable supply for the North American market and is being developed in close partnership with local indigenous communities. By integrating recycled materials, the company aims to close the local battery loop.

With its facilities, Rock Tech makes a central contribution to battery-grade material sovereignty and the achievement of climate targets. The company works in partnership with industry, policy-makers and community groups, and is committed to open communication and the highest environmental standards.
