Nutex Health Inc. told the US SEC in an 8-K dated 31 August 2026 that an unauthorised third party accessed and exfiltrated information from its servers, including patient, employee, credentialed-provider, business and financial data that is private or confidential.

A third party has threatened to post that information. The Houston company says it has not identified a material impact on operations or financial reporting systems to date, and it has not named the actor. After an earlier 24 August 8-K, a purported Texas class action (Haley v. Nutex Health, Inc., S.D. Tex.) was filed on 27 August 2026.

SecurityWeek (1 September) reports that Gentlemen (also tracked as Storm-2697) claimed the company on its leak site with a nine-day deadline; that leak-site claim is not company attribution.

No Australia link is reported.
