Insights

Financial Analyst

TL;DR Sio holds an 8.14% stake (2.93M shares), disclosed as an investment-adviser position rather than an activist stake.

This Schedule 13G/A shows a material institutional position: 2,934,027 shares with shared voting and dispositive power and 0 shares held with sole authority. As a 13G filing by an investment adviser, the position appears passive and held on behalf of affiliated funds. The disclosure is important for investor ownership tables and signals a concentrated holder, but the filing contains no indication of an intent to change control.

Corporate Governance Expert

TL;DR Ownership structure shows adviser-managed funds with shared control; GP and an individual are referenced but disclaim ownership.

The filing clarifies that voting and dispositive decisions are exercised through Sio as adviser to record owners, and that Sio GP, LLC and Michael Castor may be deemed to have control though they disclaim beneficial ownership. This distinction matters for governance analysis because legal attribution of voting power can differ from economic ownership; the record indicates centralized advisory discretion but not an asserted control position.
