Endeavor Responds to Mawson Infrastructure Lawsuit Complaint

FORT SMITH, Ark., Jan. 22, 2026 (GLOBE NEWSWIRE) -- The Endeavor Investor Group (together with its affiliates, “Endeavor” or “we”) today issued the following statement in response to the lawsuit filed by Mawson Infrastructure Group Inc. (“Mawson” or the “Company”) in the United States District Court for the District of Delaware.

"We are disappointed that the Company has chosen litigation over constructive dialogue with its shareholders," said Joshua Kilgore, principal of Endeavor. "We have made a substantial investment in Mawson based on our conviction in its long-term potential in the HPC and digital infrastructure sector. We are looking to work with management to maximize the value of Mawson for all shareholders.”

Kilgore continued. "We have acted as responsible, long-term shareholders seeking to create value. The allegations in the complaint mischaracterize the facts and our intentions. We intend to defend against these claims."

Despite this legal action, Endeavor remains committed to working constructively with Mawson to unlock shareholder value. As such, concurrent with this release, Endeavor has posted a separate release titled “A Letter to the Stockholders of Mawson Infrastructure Group Inc.”
