Amgen discloses cybersecurity breach affecting patient data

Amgen reported a cybersecurity incident that resulted in the exfiltration of protected patient health information and other proprietary data stored in cloud services managed by third‑party providers. The company disclosed the breach in an SEC filing, describing the unauthorized activity as material due to the volume and sensitivity of the files involved.

Amgen said the breach has not impacted its ability to meet patient needs, nor has it affected financial reporting, manufacturing operations, or product supply. The firm expects no effect on its financial condition.

The company emphasized its commitment to privacy and security, noting that it will make required regulatory and legal notifications as the investigation continues.
