SEC Reporting Analyst

Insider group reported selling 250,000 shares; large indirect stake remains. Net impact neutral.

This Form 4 discloses a sale of 250,000 ordinary shares on 11/06/2025 at $10.425 per share. After the transaction, the reporting persons show 2,048,679 shares beneficially owned indirectly. The filing is made by more than one reporting person and reflects a complex ownership chain across Harraden entities, with managing member Frederick V. Fortmiller, Jr. signing for each. No derivative securities are reported.

The group is identified as a Director and 10% Owner. Beneficial ownership is disclaimed except for pecuniary interest, which is standard when multiple affiliated entities hold the shares. The sale reduces the aggregated indirect holdings but leaves a sizable position, suggesting continued exposure. There is no indication of a 10b5-1 plan in this disclosure, and no options, warrants, or converts are listed.

Key items to watch: subsequent Form 4s for continued disposition activity, any shifts in the reported ownership form (direct vs. indirect), and whether the group’s status as a 10% owner changes over time. The signatures are dated 11/10/2025, aligning with timely reporting.
