See ECF No. 134 at 2-15.

ECF No. 30 at ¶¶ 119-53. The complaint alleges that Shipman,

On March 14, 2023, Shipman filed an answer to StoneX’s complaint, and he asserted

various counterclaims in his answer. ECF No. 56. Shipman also filed a declaration in connection with his answer and counterclaims, to which he attached an exhibit that displayed a “full and complete copy” of certain StoneX source code. See ECF No. 56 at ¶ 276 n.5; ECF No. 57-1. In his answer, Shipman asserted that the code had been illegally taken from BTIG by a StoneX employee who was a former BTIG employee. See, e.g., ECF No. 56 at ¶¶ 226, 258-62. Shipman moved to file both his answer and his supporting declaration under seal. See ECF No. 55. The Court granted the motion to seal but directed Shipman to file redacted versions of the answer and declaration on the public docket. Id. Shipman filed a redacted version of his answer on April 24, 2023. See ECF No. 71. B. BTIG’s suit against StoneX BTIG, a competitor of StoneX, is a financial services firm. ECF No. 139 at 5. In 2023, BTIG “was alerted” that its former employees may have stolen substantial portions of source

code and related proprietary information for use by StoneX in trading products. Id. Following an internal investigation, BTIG confirmed that former employees now working for StoneX had taken software code and other data before leaving BTIG. Id.; see also ECF No. 140-2 at ¶ 87. BTIG and StoneX subsequently retained an independent forensic expert to compare a limited portion of the StoneX code identified by Shipman in the documents filed in this case against a limited portion of BTIG’s code that BTIG suspected had been taken by former employees. ECF No. 139 at 5. The forensic expert found “dozens of instances” where BTIG code “appear[ed] verbatim in StoneX’s systems,” which he opined could not “be explained in any way other than copying.” Id.; ECF No. 140-2 at ¶ 84. On November 11, 2023, BTIG sued StoneX in California state court. ECF No. 139 at 6; see also ECF No. 143 at ¶ 2; ECF No. 143-1; BTIG, LLC v. StoneX Group, Inc. et al., No. CGC-23-610525 (Cal. Sup. Ct., S.F. Cty). C. The instant motion On March 8, 2024, BTIG moved pursuant to Rule 24 of the Federal Rules of Civil Procedure for permissive intervention for the limited purpose of obtaining access to certain

materials filed under seal in this case. ECF Nos. 138-40. Specifically, BTIG seeks access to unredacted versions of: (1) StoneX’s complaint; (2) StoneX’s memorandum of law in support of its motion for a temporary restraining order; (3) the Declaration of Evan Pfeuffer; (4) the Declaration of Christopher Amato; (5) the Declaration of Michael Wareman and Exhibit 2 to that declaration; (6) the Declaration of R. Cuyler Robinson; (7) Shipman’s January 27, 2023 Declaration; and (8) Shipman’s Answer, Counterclaims, and Supporting Declaration dated March 13, 2023. See ECF No. 139 at 6-7; see also ECF Nos. 30, 31, 32, 33, 35, 35-2, 36, 37-1, 51, 56, 57, 57-1, 67, 71 (sealed and redacted copies of requested materials). BTIG believes that these materials may contain “the BTIG software code that was stolen and integrated into StoneX’s trading systems and products,” or facts or other evidence showing the transmission of

BTIG’s code from StoneX’s systems. ECF No. 139 at 7. BTIG requests access to all this material on an attorneys’ eyes-only basis, limited to outside counsel for BTIG. ECF No. 139 at 4.
