Schedule 13G/A shows Alta Partners' passive 0.09% stake in CEA Industries

Rhea-AI Filing Summary

Alta Partners LLC filed an amended Schedule 13G reporting ownership in CEA Industries Inc. common stock. The filing states 39,180 shares beneficially owned, described as shares issuable upon exercise of warrants, and reports this stake as 0.09% of the class. The filing also contains an aggregate line showing 38,180 shares and 0.1%, an internal inconsistency the document does not reconcile.

Positive

• Position described as passive, held in the ordinary course and not to influence control

• Very small ownership stake of approximately 0.09%, unlikely to affect governance

Insights

Institutional Ownership Analyst

Minor passive stake reported; filing shows an internal shares discrepancy.

The filing records a small, passive position in CEA Industries Inc. consisting of warrants convertible into common stock, with the filer claiming 39,180 beneficial shares (0.09%).

This position is explicitly described as held in the ordinary course and not for control; however, an aggregate line shows 38,180 and 0.1%, creating a clear numeric inconsistency to resolve. Watch for corrected amendments if reconciliation is required within regulatory timelines.

Compliance & Filings Specialist

Filing appears routine but contains conflicting internal figures that may prompt clarification.

The statement follows Schedule 13G format: issuer name, CUSIP 86887P101, filer identity, and an explicit certification that the stake was not acquired to influence control. Signature by Steven Cohen on 10/10/2025 is included.

Given the mismatch between 39,180 and 38,180 shares, a corrective amendment is a plausible near-term outcome if the filer discovers the error; monitoring the SEC filings for an amendment is appropriate.
