Insights

Securities Analyst

TL;DR: Routine Form 144 disclosing a proposed sale of 10,000 Ionis shares on 08/06/2025; key identity details are missing from the filing.

The notice documents a proposed sale of 10,000 common shares via Stifel Nicolaus on 08/06/2025 with an aggregate market value of $419,292.00. Acquisition records show these shares originated as Restricted Stock Units on 01/15/2017 (42,223 units acquired) and were paid for in cash. The filing does not include the filer name, CIK, or submission contact details, which limits ability to assess insider status or intent. No sales in the prior three months are reported.

Corporate Governance Expert

TL;DR: Disclosure meets Rule 144 mechanics but omits filer identification; materiality to shareholders is not determinable from this filing alone.

The Form 144 specifies the broker (Stifel Nicolaus & Company Inc), class (Common Stock), proposed sale date (08/06/2025) and aggregate value ($419,292.00). It documents the acquisition as RSUs dated 01/15/2017. Crucial identifying information (filer name/CIK) is absent from the provided content, preventing assessment of officer/director/affiliate status or compliance context beyond the mechanics disclosed.
