What happened
According to a headline listing from SEC EDGAR, dated 2026-10-27, Repligen Corp discloses a cyber incident in an SEC Form 8-K filing.
The document at that URL is Exhibit 99.1. It is a press release titled “Repligen Reports Third Quarter 2026 Financial Results and Updates Full Year 2026 Financial Guidance” (SEC EDGAR). In the text available for this advisory, the exhibit covers quarterly revenue, the completed BioLife Solutions acquisition, a new training center in Seoul and updated financial guidance. It does not mention a cyber incident.
The following details are not confirmed by the sources:
- What kind of incident occurred.
- When it was detected.
- Which systems were affected.
- Whether any data was accessed.
- Whether operations were disrupted.
- Who was responsible.
The SEC EDGAR filing is the only source provided for this advisory. No independent report is among those sources.
Am I affected?
Not confirmed. The sources do not name any affected products, systems, customers or data types. Repligen describes itself as a global bioprocessing company serving biopharmaceutical developers, manufacturers and CDMOs (SEC EDGAR). Nothing in the sources links an incident to any of these customers.
What to do now
- Read Repligen’s 8-K filings on SEC EDGAR directly to see any incident description the company provides (SEC EDGAR).
- If you are a Repligen customer or supplier, rely on direct communication from Repligen rather than secondary reports.
- Do not assume any data exposure, attacker or impact until Repligen or another official source states it.
