Insights

Financial Analyst

TL;DR The filing discloses no beneficial ownership by these reporting persons, indicating no voting or dispositive influence.

The Schedule 13G/A shows each reporting person holds zero shares and zero voting or dispositive power as of June 30, 2025, and reports 0.0% ownership of the class. This is a routine disclosure that confirms these entities and the individual have no current economic stake or voting influence to report. From a capital markets perspective, the filing is neutral: it does not signal accumulation or disposition activity by these parties.

Corporate Governance Expert

TL;DR The amendment documents absence of beneficial ownership and reiterates non-group status; governance impact is minimal.

The reporting persons expressly disclaim group status and certify the shares were not acquired to influence control. With all rows reflecting zero sole and shared voting and dispositive power, there is no change to governance or shareholder voting dynamics attributable to these filers. The inclusion of the joint filing agreement by reference is procedural and does not alter substance.
