Negatives

• The potential for deemed beneficial ownership of 81.38% (if excluded shares were included) suggests a complex ownership structure and potential for significant influence that is not fully reflected in the primary reported percentage.

Risks

• Potential for the reporting persons to be deemed members of a 'group' with other stockholders due to director nomination and voting agreements, which could have implications under securities regulations.
• The exclusion of shares held by Dirk Wallinger and parties to voting agreements from the primary reported beneficial ownership could lead to misinterpretation of the reporting persons' actual influence or control.
