**Comment for Type of Reporting Person:** This filing is to convert from Schedule 13D to Schedule 13G because the Reporting Persons' reasons for filing on Schedule 13D have ceased to be true for some time. The Reporting Persons are no longer the largest shareholder of Trustmark, and there is no longer any representative of either Reporting Person on the Board of Trustmark. Thus, the Reporting Persons are now passive investors. Since the last filing, Trustmark has repurchased shares. As a result, our beneficial ownership position was again above the 5% threshold, and we are filing to report that in light of our prior status as a Schedule 13D filer. However, we are also filing to report the sale of 40,000 shares on February 4, 2026 and 35,000 shares on February 5, 2026, which places us below the 5% threshold on the day before we file this Schedule 13G. Therefore, this will also be our exit Schedule 13G filing.
