On April 7, 2023, the Company filed a suit against Gryphon in the U.S. District Court for the Southern District of New York. The Company alleges, among other things, that Gryphon materially breached its obligations to the Company, both its contractual duties under the Gryphon MSA dated August 19, 2021, and its fiduciary duties, including as a custodian of the Company’s assets. On August 22, 2023, Gryphon asserted counterclaims alleging breach of contract, breach of the implied covenant of good faith and fair dealing, negligence in managing its computer systems, and defamation. On November 7, 2023, Gryphon voluntarily dismissed its defamation claim. Gryphon has amended its complaint several times, and on December 14, 2023, added a second breach of contract claim predicated on another alleged breach of the Gryphon MSA. On February 2, 2024, the Company filed a partial motion to dismiss the second breach of contract claim, the negligence claim, and the breach of the implied covenant claim for failure to state a claim. On February 16, 2024, the court so-ordered a stipulation agreed to by the parties dismissing the second breach of contract claim, the negligence claim, and the breach of the implied covenant claim with prejudice. The so-ordered stipulation expressly preserves the Company’s ability to seek the recovery of its costs and attorney’s fees incurred in connection with the dismissed claims. The Company disputes the allegations against it and intends to vigorously defend itself and to vigorously pursue its claims against Gryphon. At this preliminary stage, the Company believes that Gryphon’s claims lack merit; however, because this litigation is still at this early stage, the Company cannot reasonably estimate the likelihood of an unfavorable outcome or the magnitude of such an outcome, if any. |
