When did Blackrock, Inc. buy into Certara, Inc.?
The filings give report dates, not purchase dates. The earliest filing from Blackrock, Inc. on this page is the Schedule 13G/A, filed 2026-07-08, reporting 11.6%. That earliest filing is itself an amendment, which updates an earlier report.

It is not an audit and not a full cap table: holders who never reached 5% are not listed, and a stake can change after its latest filing.
