[SCHEDULE 13G] Camp4 Therapeutics Corp SEC Filing

Rhea-AI Filing Summary

Coastlands-affiliated entities and Matthew D. Perry reported holding an aggregate of 4,886,722 shares of Camp4 Therapeutics Corp common stock. The filing lists that amount as representing 10.0% of the class on the cover sheets and as 9.99% in Item 4, reflecting the reporting persons' calculation based on 20,161,073 shares outstanding as of August 5, 2025 and an additional 26,681,053 shares issued in a private placement that closed September 11, 2025. Each reporting person disclaims beneficial ownership except to the extent of pecuniary interest and states the shares are held in the ordinary course of business and not to influence control of the issuer. All reporting persons show shared voting and dispositive power over the 4,886,722 shares and no sole voting or dispositive power.

Positive

• Clear, consistent disclosure of aggregate holdings (4,886,722 shares) across all reporting persons
• Certification that the securities are held in the ordinary course of business and not to influence control
• Detailed basis for percentage calculation referencing outstanding share counts and the private placement

Negative

• Percentage discrepancy within the filing: cover sheets show 10.0% while Item 4 reports 9.99%, which may require reconciliation
• No sole voting or dispositive power reported, indicating limited unilateral control despite the sizeable stake

Insights

Securities Analyst

TL;DR: Coastlands and affiliated persons disclose a near-10% stake (4,886,722 shares) with shared control, filed on Schedule 13G.

This Schedule 13G shows the reporting persons collectively hold 4,886,722 shares of CAMP common stock, presented as ~10% of the class using a specific outstanding-share calculation. The filing follows passive-investor disclosure conventions: ownership is reported under Rule 13d-1(b)/(c)/(d) formats, with certifications that the position is held in the ordinary course of business and not for control. Shared voting and dispositive power are asserted across the listed entities and an individual, while each disclaims group membership and sole control. The disclosure and the percent near the 10% threshold could affect monitoring and disclosure obligations but the filing itself states no intent to influence control.

Corporate Governance Expert

TL;DR: Filing documents coordinated ownership across multiple Coastlands entities and a control person, with formal disclaimers of group status and control intent.

The Schedule 13G aggregates ownership across Coastlands Capital LP, Coastlands Capital Partners LP, Coastlands Capital GP LLC, Coastlands Capital LLC and Matthew D. Perry, each showing identical share counts and classifications. The document includes standard disclaimers that the Partnership’s filing does not constitute an admission of beneficial ownership under Rule 13d-3 and affirms the ordinary-course nature of the holdings. Signatures from the Chief Operating Officer and Matthew D. Perry certify accuracy. From a governance standpoint, the filing appropriately documents beneficial interest and control relationships without asserting sole control or active control intentions.
