Insights

Securities Analyst

TL;DR: Routine Form 144 filing reporting an insider sale of 10,000 shares valued at $503,671; small relative to outstanding stock.

The filing documents a proposed brokered sale of 10,000 Ionis shares via Stifel Nicolaus with an aggregate market value of $503,671. The securities were acquired as restricted stock units on 01/15/2019 and previously a sale of 10,000 shares occurred on 08/05/2025 for $428,593. Given 159,391,229 shares outstanding, the proposed sale is roughly 0.0063% of the float, which is immaterial from a market-cap perspective. The filing includes the standard insider attestation regarding material nonpublic information.

Corporate Governance Expert

TL;DR: Filing reflects compliance with Rule 144 disclosure for an insider sale; nothing in the record indicates regulatory or governance concerns.

The notice provides required disclosure elements: broker name and address, quantity, aggregate market value, acquisition date and nature (restricted stock units), and recent sales within three months. The inclusion of the prior sale on 08/05/2025 and the attestation statement supports procedural transparency. There are no statements of plan adoption dates for Rule 10b5-1 in the remarks section.
