Second, the parties agree to amend the Deadline to Complete Fact Discovery and File Motions to Compel Discovery from January 18, 2028, to December 15, 2027.

This deadline already appears in the Case 2:26-cv-00339-JRG Document 33 Filed 08/20/26 Page 2 of 4 PageID #: 307 “Additional Requirements” section of the Docket Control Order, and the parties propose adding it to the chart to aid in tracking deadlines.
