[144] Ionis Pharmaceuticals, Inc. SEC Filing

Rhea-AI Filing Summary

Alpine Associates Management Inc. has filed a Schedule 13G disclosing ownership of 1,496,319 Class A shares of Radius Recycling, Inc. (CUSIP 806882106) as of 30 June 2025. The position equals 5.34 % of the outstanding class, triggering the 5 % reporting threshold under Section 13(d) of the Securities Exchange Act.

Alpine, a Delaware-organized investment adviser, reports sole voting and sole dispositive power over the entire stake and specifies that the shares were acquired and are held in the ordinary course of business, with no intent to influence control (passive “13G” filing, not activist “13D”). The certification is signed by Chief Compliance Officer Christian Marzullo on 5 Aug 2025.

Positive

• Alpine Associates’ 5.34 % stake introduces a new institutional holder, potentially broadening the shareholder base and signalling outside confidence in Radius Recycling.

Negative

• None.

Insights

Securities Analyst

TL;DR: Passive 5.3 % stake disclosed; institutional interest noted but no control intent—overall neutral impact.

The Schedule 13G confirms that Alpine Associates now owns 1.50 M Radius Recycling Class A shares, exceeding the 5 % threshold. Because the filing is on Form 13G, Alpine represents it is a passive investor and does not seek to change or influence control, limiting near-term strategic implications. Nonetheless, a new mid-sized institutional holder can enhance market liquidity and may be viewed positively by some investors. Absent activist intent or additional transactions, the disclosure is best classified as informational rather than a catalyst.
