Insights

Financial Analyst

TL;DR: Nantahala reports a 5.18% beneficial stake in Surrozen, including exercisable warrants that materially contribute to the position.

The filing discloses a 455,299-share position equal to 5.18% of Surrozen's common stock, with 225,772 shares exercisable via warrants within 60 days. For investors, the combination of direct holdings and near-term exercisable warrants clarifies potential dilution and voting-power calculations. The filing classifies Nantahala as an investment adviser filing under Rule 13d-1(b), and the reporting persons explicitly state the holdings are ordinary-course and not intended to influence control.

Corporate Governance Expert

TL;DR: A >5% disclosure triggers SEC Schedule 13G obligations; the filing affirms passive intent and shared voting/dispositive power.

The report shows shared voting and dispositive power over all 455,299 shares for Nantahala and its two principals, with zero sole voting or dispositive power reported. The statement includes the required certification that the holdings are not held to influence control, consistent with Schedule 13G rather than a 13D. This distinction is important for governance oversight and market transparency.
