Altium Files Schedule 13G/A for 21,008 Greenlane (GNLN) Shares

Rhea-AI Filing Summary

Altium Capital Management LLC, Altium Healthcare Long Short Onshore Fund LP and Altium Healthcare Long Short GP LLC jointly report beneficial ownership related to Greenlane Holdings, Inc. common stock (CUSIP 395330509). The filing shows 21,008 shares of common stock that would be issuable upon full conversion/exercise of Series A Warrants, representing 0.12% of the class based on 17,394,226 shares outstanding as reported by the issuer. The reported counts do not give effect to a 4.99% Warrant Blocker, which prevents the Reporting Persons from exercising warrants if doing so would increase their ownership above 4.99%, so the actual post-blocker ownership is lower than reported.

The filing discloses that the Fund is the direct record owner and that Altium Capital Management LLC and Altium Healthcare Long Short GP LLC may be deemed to beneficially own the securities due to advisory and general partner roles. The parties certify the securities were not acquired to change or influence control of the issuer.

Positive

• Disclosure of 21,008 shares issuable on conversion of Series A Warrants provides transparent quantification of potential dilution and interest
• Clear disclosure of a 4.99% Warrant Blocker that limits exercise and clarifies the maximum potential ownership outcome
• Joint filing by Altium entities clarifies advisory and GP relationships and the source of deemed beneficial ownership

Negative

• None.

Insights

Securities Analyst

TL;DR: Small, non-controlling position disclosed; warrants noted but limited by a 4.99% blocker.

The Schedule 13G/A records 21,008 shares attributable to Altium entities via Series A Warrants, equal to 0.12% of the outstanding common stock on the issuer's reported share base. The filing explicitly states a 4.99% Warrant Blocker, and the reported numbers do not reflect the blocker, meaning actual exercisable ownership will be lower. Item 10 includes a certification that the position was not acquired to influence control, consistent with a passive 13G reporting posture. Materiality to shareholders appears limited given the small percentage of the class.

Corporate Governance / Risk Analyst

TL;DR: Disclosure is clear on ownership mechanics and limits; negligible governance impact at reported levels.

The filing names the Fund as the direct record owner and identifies Altium Capital Management LLC and the GP as advisor and general partner respectively, clarifying relationships that can create deemed beneficial ownership. The inclusion of the Warrant Blocker and the explicit statement that the securities were not acquired to change control reduce potential governance concerns. With only 0.12% reported, there is no indication of a control threat or group formation affecting board composition from this disclosure alone.

The Series A Warrants are subject to a 4.99% blocker (the "Warrant Blocker"). The Reporting Persons are subject to a Warrant Blocker and as a result cannot exercise the Series A Warrants to the extent the Reporting Persons would beneficially own, after any such conversion or exercise, more than 4.99% of the outstanding shares of Common Stock. However the securities reported in rows (6), (8) and (9) show the number of shares of Common Stock that would be issuable upon full conversion and exercise of such Warrants and does not give effect to the Warrant Blocker. Therefore, the actual number of shares of Common Stock beneficially owned by each such Reporting Person, after giving effect to such Warrant Blocker, is less than the number of securities reported in rows (6), (8) and (9).The securities reported in rows (6), (8) and (9) of each Cover Page are inclusive of the following: 21,008 shares of Common Stock issuable up conversion of Series A Warrants.
