Amgen (AMGN) has found no material impact on its financial condition or operations following a cybersecurity breach, the company said Friday in a filing.

The drugmaker identified unauthorized activity this month involving data stored in cloud systems operated by third- party providers. The incident resulted in the exfiltration of some company data, including patient and proprietary information, it said.

Amgen continues to assess the potential impact of the incident and is reviewing its regulatory and legal notification requirements.
