Insights

Financial Analyst

TL;DR: Director received 2,272 RSUs vesting in one year; ownership after grant is 10,645 shares — routine insider equity grant.

The filing documents a non-cash issuance of 2,272 restricted stock units to a company director on 08/28/2025, with vesting scheduled for 08/28/2026 and a reported price of $0. This increases the reporting person’s beneficial ownership to 10,645 shares. There are no cash purchase details, option exercises, or derivative transactions disclosed. From a financial perspective, this is a standard equity compensation event that affects outstanding equity only when the RSUs vest and convert to shares.
