SEC EDGAR · 1 source
What's on the official record
Astrana Health, Inc. (ASTH) filed a Form 8-K with the SEC on 23 September 2026, classifying the filing under Item 1.05 (material cybersecurity incidents). The period ending is 22 September 2026, CIK 0001083446, state CA, SIC 8742. The accession number is 0001104659-26-109813 at https://www.sec.gov/Archives/edgar/data/1083446/000110465926109813/0001104659-26-109813-index.htm. The indexed row carries filing facts only — form 8-K, Item 1.05, the filing date, and the accession number. The filing text is the record for any cause, attacker, data type, customer impact, or loss; the row states none of those.
Assessment
For a deal team, the record confirms the filing itself — the form, the Item 1.05 classification, the filing date, and the accession number — and nothing about the incident's cause, scope, or financial effect. Scope diligence and price against the filing text at the accession number, which is where any materiality, remediation, or impact language would appear.
For a credit committee, the record establishes that a material cybersecurity incident disclosure was filed on 23 September 2026, without stating any loss, exposure, or remediation cost. Monitor the filing text for any covenant-relevant impact before pricing or waiving terms tied to the incident.
For a cyber underwriter, the record confirms an Item 1.05 material cybersecurity incident filing by Astrana Health, Inc. on 23 September 2026, with no cause, data type, or control detail stated in the indexed row. Read the filing text to determine what to require or exclude before binding or pricing coverage.
What would change this call
Any cause, attacker, data type, customer impact, or loss stated in the filing text at the accession number would change what each reader can check or decide. A subsequent amendment or 8-K updating the incident would also change the call.
