Greenland Energy is trading 7.26% lower at $4.96, with no reliable company-specific announcement identified to explain the September 25 decline. - The stock sharply reversed from its September 24 close of $5.35 after an 83.85% surge. - The company extended Jameson Land exploration-well deadlines through December 31, 2028, while assuming direct drilling-permit and operational responsibilities; that news was associated with the prior rally and does not clearly explain the decline. Trading remains highly volatile.
