Item 1.05 Material Cybersecurity Incidents.
AdaptHealth Corp. (the “Company”) is investigating a security incident whereby a threat actor gained unauthorized access to Company systems and exfiltrated certain data therefrom. Upon learning of the incident, the Company promptly activated its incident response procedures, launched the investigation with the support of external advisors and cybersecurity experts to assess and contain the threat and notified law enforcement. While the investigation is ongoing, the Company has been able to confirm certain facts about the incident, and on June 27, 2026, the Company determined that the incident is material, due to the nature and potential volume of the data that is at risk.
Specifically, based on information obtained to date, the Company believes that a threat actor gained unauthorized access to certain of the Company’s cloud-based business applications, including certain internal patient management systems and document storage platforms. On June 15, 2026, the Company received a communication from a threat actor claiming to have obtained certain data from the Company’s systems. The Company has confirmed that certain data was exfiltrated from its systems including a stored password file associated with insurance billing; the Company also has confirmed that certain external electronic health record system portals were accessed by the threat actor.
The data affected includes passwords associated with insurance billing and certain personally identifiable information and protected health information of patients. The Company does not collect Social Security numbers in the affected systems and does not store individual financial account information or payment card information in those systems.
The incident was the result of a successful social engineering attack that compromised a user session associated with a third-party contractor. Following detection, the Company promptly implemented containment measures, including disabling the compromised user account, resetting affected credentials, and implementing additional access controls, and the incident has been contained.
To the extent any information required by Item 1.05 of Form 8-K was not determined or was unavailable at the time of this filing, the Company will amend this Current Report on Form 8-K as such information is determined or becomes available.
