On Appeal from the Business Court Division 1B Dallas County, Texas Trial Court Cause No. 24-BC01B-0010

MEMORANDUM OPINION

This is an interlocutory appeal of an order of the business court order granting the special appearances of two defendants.1 Appellants Primexx Energy Opportunity Fund, LP and Primexx Energy Opportunity Fund II, LP inform us in a “Notice of Merged Appeal” that the business court’s order has merged into a final judgment.2 This Court docketed their appeal from the final judgment under cause No. 15-25- 00120-CV. Appellants intend to move forward with their challenge to the special appearances in that appeal. We treat the Notice of Merged Appeal as a motion to dismiss cause No. 15-25-00095-CV, grant the motion, and dismiss the appeal.3
