Insights

Insider Transactions Analyst

Multiple same‑entity sales across Feb–Apr 2026 indicate routine dispositions rather than a single block trade.

The record lists numerous dated sales by Susan Ocampo with discrete share counts and dollar figures per trade, executed via Goldman Sachs & Co. LLC. The pattern includes repeat sale sizes (100,000; 200,000) and a largest listed trade of 261,763 shares.

These entries should be read as individual dispositions reported under resale/section 144 procedures; proportionality relative to total holdings is not provided here, so investment impact cannot be assessed from this excerpt alone.

Securities Compliance Specialist

The filing documents compliance with resale reporting by listing dates, quantities, and amounts for each transaction.

The table format and broker designation (Goldman Sachs & Co. LLC) align with standard resale/disposition reporting. Each row ties a trade date to a share count and a numeric amount which appears to be gross proceeds.

Absent additional context (total beneficial ownership, trading plan references), this remains a record of reported dispositions rather than an indication of regulatory exception or violation.
