Boston Scientific files 8-K Item 1.05 material cybersecurity incident

What's on the official record

Boston Scientific Corp (BSX) filed a Form 8-K with the SEC on 8 September 2026, classifying the filing under Item 1.05 (material cybersecurity incidents). The filing carries accession number 0000885725-26-000059 in the EDGAR index at https://www.sec.gov/Archives/edgar/data/885725/000088572526000059/0000885725-26-000059-index.htm. The indexed row states filing facts only: form 8-K, filing date 8 September 2026, Item 1.05, CIK 0000885725, state MA, SIC 3841. It states no cause, attacker, data type, customer impact, or loss; the filing text at the accession number is the record for those details.

Assessment

For a deal team, the record supplies the form, filing date, Item 1.05 classification, and accession number needed to pull the filing text. Scope diligence to that text for any stated cause, data type, customer impact, or loss before pricing or conditioning a transaction. The indexed row itself states none of those.

For a credit committee, the record gives an Item 1.05 material-cybersecurity-incident filing under CIK 0000885725 and its accession number. Read the filing text for any stated effect on operations, customer data, or financial position before setting, pricing, or covenanting a facility. The indexed row alone carries no loss or impact figure.

For a cyber underwriter, the record provides a dated Item 1.05 filing and accession number to open the filing text. That text is where any stated cause, data type, or scope would support deciding whether to bind, price, exclude, or require a control on a policy. The indexed row lists only filing metadata.

What would change this call

A later 8-K or amendment under CIK 0000885725 that changes the reported Item number, or filing text that names a cause, attacker, data type, customer impact, or loss, would change what each reader can check or decide.

What to check next
