[SCHEDULE 13G] TriSalus Life Sciences, Inc. SEC Filing

Rhea-AI Filing Summary

TriSalus Life Sciences received a Schedule 13G reporting that Nantahala Capital Management, LLC and its managing members, Wilmot B. Harkey and Daniel Mack, each may be deemed the beneficial owner of 2,000,000 shares of TriSalus common stock, representing 5.29% of the class as of June 30, 2025. The filing states the shares are held by funds and separately managed accounts under Nantahala's control, and the reported position reflects shared voting and dispositive power only, with no sole voting or sole dispositive authority. The Reporting Persons certify the shares were acquired in the ordinary course of business and not for the purpose of changing or influencing control of the issuer.

Positive

• Material disclosure: Reporting of a >5% position (5.29%) increases transparency for investors
• Passive intent stated: Certification that shares were acquired in the ordinary course and not to influence control

Negative

• No sole voting or dispositive power: Reporting Persons do not have unilateral control over the shares

Insights

Securities Analyst

TL;DR: A single adviser and its principals report a >5% stake (5.29%), signalling a material passive stake with shared control only.

The Schedule 13G shows Nantahala and two principals collectively control 2,000,000 shares, meeting the disclosure threshold for a passive investor under Rule 13d-1. The position is reported with shared voting and dispositive power and no sole authority, which suggests coordinated reporting across affiliated accounts rather than concentrated ownership by one individual. The certification that the stake is held in the ordinary course and not to influence control reduces the likelihood of imminent activism, but the >5% ownership is material and may attract market attention depending on trading volume and float.

Corporate Governance Expert

TL;DR: Ownership crosses the 5% disclosure threshold but shows no sole control, implying limited governance influence at this stage.

The filing attributes shared voting and dispositive powers to Nantahala and its managing members, indicating the stake is held across funds/accounts managed by the adviser. Because there is no sole voting power, the Reporting Persons lack unilateral ability to direct corporate actions. The explicit certification that the holdings are not intended to change control is consistent with a passive investment profile, though ongoing monitoring of future filings would be warranted to detect any shift toward active engagement.
