Gold Resource Corporation Completes Merger with Goldgroup Mining Inc.

Gold Resource Corporation announced the completion of its merger with Goldgroup Mining Inc. on July 17, 2026. The transaction, initially agreed upon in January 2026 and amended in May 2026, resulted in Gold Resource Corporation becoming a wholly owned subsidiary of Goldgroup. Shareholders of Gold Resource Corporation received 1.4476 shares of Goldgroup's common stock for each share they held, a ratio adjusted due to a prior share consolidation by Goldgroup. Outstanding stock options, deferred share units, and restricted share units were converted into equivalent awards for Goldgroup's shares. In connection with the merger, Gold Resource Corporation requested the suspension and withdrawal of its common stock from the NYSE American. The company also plans to suspend its reporting obligations under the Securities Exchange Act. The merger signifies a change in control, with Goldgroup now owning the entirety of Gold Resource Corporation. Consequently, certain directors of Gold Resource Corporation ceased their roles. The articles of incorporation and bylaws of Gold Resource Corporation have been amended to reflect these changes.
