Rock Tech Lithium Announces Plans to Dual-List on NASDAQ and Filing of Short Form Base Shelf Prospectus

• Company Files Preliminary Short Form Base Shelf Prospectus and AIF and continues to advance NASDAQ Dual Listing via MJDS Process
• Final Base Shelf Prospectus, if receipted, will be valid for 25 months and is intended to provide the Company with capital markets flexibility

Toronto, ON, April 27, 2026 — Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the “Company” or “Rock Tech”) is pleased to announce that it has  filed a preliminary short form base shelf prospectus (“Base Shelf Prospectus”) and Annual Information Form (“AIF”)  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 roadmap — which the Company expects may be used, subject to receipt and regulatory approvals, in connection with a potential NASDAQ dual‑listing through the Multi-Jurisdictional Disclosure System (“MJDS”), the established bilateral framework between Canadian and U.S. capital markets regulators.

NASDAQ Dual-Listing Readiness via MJDS

Under the MJDS framework, eligible Canadian issuers may file a U.S. registration statement with the U.S. Securities and Exchange Commission (“SEC”) 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 (the “TSXV”) 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 TSXV‑listed issuers and is intended to support corporate governance practices, capital markets readiness, and financing flexibility. It is standard practice among established TSXV-listed resource and technology companies operating at Rock Tech’s scale. The filing reinforces Rock Tech’s positioning as a strategic, investment-ready critical minerals 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 re-rating 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 CEO, Mirco Wojnarowicz.

Rock Tech is advancing toward a NASDAQ dual-listing as a cornerstone of its institutional investor strategy. With the Guben Converter holding EU CRMA Strategic Project status and a full permit and engineering package, the Red Rock Converter project in Ontario, Canada carrying a CAD $2.3 billion NPV 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 re-rating catalyst — expanding visibility, research coverage, and shareholder liquidity across the world’s deepest capital market.
