8-K - Avantor, Inc. (0001722482) (Filer)
Regulatory Filings Classification · 95% confidence The document is a Form 8-K filed with the SEC, dated April 29, 2026, reporting the issuance of a press release announcing financial results for the quarter ended March 31, 2026. The text states that the press release is attached as Exhibit 99.1 and incorporated by reference, but the Form 8-K itself does not contain the full financial results or detailed financial statements. The document is short (3386 characters) and primarily serves as a current report announcing the earnings release rather than the earnings release itself. According to the rules, such a document is classified as an Earnings Release (ER) if it contains key highlights only, but since this is a Form 8-K referencing a press release, it is best classified as a Regulatory Filing (RNS) because it is a general regulatory announcement and does not contain the full earnings data itself. Therefore, the appropriate classification is Regulatory Filings (RNS).

Board/Management Information Classification · 100% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce unscheduled material events or corporate changes. The content specifically details changes in senior management, including the departure of an executive and the hiring of a new executive. There are no financial statements or detailed financial data presented, and the document is relatively short (4050 characters). The primary focus is on management changes, which aligns with the Board/Management Information category. Therefore, the appropriate classification is MANG (Board/Management Information).

8-K - Avantor, Inc. (0001722482) (Filer)
Board/Management Information Classification · 100% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events that shareholders should know about. The content specifically details the resignation of a key executive (the CFO) and the appointment of an interim CFO, including compensation arrangements. This fits the description of announcements related to changes in the company's board of directors or senior management. There are no financial statements or detailed financial data presented, so it is not an Annual Report, Interim Report, or Earnings Release. The document is not a proxy statement, voting results, or a regulatory filing of another type. Therefore, the most appropriate classification is Board/Management Information (MANG). The document length and detail support a high confidence in this classification.
