Tactical Resources and Plum Acquisition Corp. III receive Nasdaq approval; close July 28, 2026

Resulting Issuer to Trade on Nasdaq under Ticker Symbol “TREO” Tactical Resources Corp . (TSXV:RARE) (OTC:USREF) (“ Tactical ” or the “ Company ”), a U.S.-focused rare earth elements development company, today announced that it has received an approval letter from the Nasdaq Listing Center for the listing of the common shares of the resulting issuer (“ New PubCo ”) and the trading of those shares on the Nasdaq Capital Market upon completion of the business combination (the " Business Combination ") with Plum Acquisition Corp. III (OTC:PLMJF) (“ Plum ”). The Business Combination is being effected pursuant to a business combination agreement (the " Business Combination Agreement ") dated August 22, 2024, as amended, entered into among the Company, Plum, Plum III Amalco Corp. (" Amalco "), and Plum III Merger Corp. (" PubCo " and collectively with the Company, Plum and Amalco, the " Parties "). Pursuant to the Business Combination Agreement, following a series of amalgamation transactions, Tactical will continue as a wholly-owned subsidiary of a new parent entity (" New PubCo "), which will be renamed "Tactical Resources Corp." Under the Business Combination, common shares in the capital of Tactical (" Tactical Shares ") will be exchanged for common shares of New PubCo (" New PubCo Common Shares ") at an exchange ratio to be determined at closing (the " Closing ").

Following the Closing, New PubCo Common Shares will begin trading on the Nasdaq Stock Market under the ticker symbol "TREO". The completion of the transaction positions Tactical to accelerate development of its Peak Project in Hudspeth County, Texas - a rare earth asset in the United States with existing mined material, established infrastructure, and a clear pathway toward near-term processing and scale. “As we prepare to enter the public markets, our focus remains on disciplined execution,” said Ranjeet Sundher, Chief Executive Officer of Tactical. “We are advancing our technical work programs, strengthening our operational foundation, and positioning the Company to deliver measurable progress as a public company.” “This transaction brings Tactical to an important inflection point,” said Kanishka Roy, Chief Executive Officer of Plum Acquisition Corp. III. “Rare earths sit at the center of national security, advanced manufacturing, and energy transition priorities, yet viable near-term supply remains scarce. Tactical stands out for its asset quality, execution readiness, and experienced leadership team.” The Closing is expected to occur on or about July 28, 2026, and remains subject to the satisfaction or waiver of customary closing conditions, including receipt of final approval of the TSX Venture Exchange (the “TSXV”).

The Company has applied for, and expects to be delisted from, the TSXV following the Closing. A further release will be disseminated closer to Closing confirming closing exchange ratio and other relevant information for shareholders.
