Positive

• Brokered sale via Raymond James indicates use of an established execution channel
• Securities were acquired publicly on 07/02/2021, showing an established holding date that supports Rule 144 eligibility
• Recent small-block sales (6,966 shares) suggest orderly, incremental dispositions rather than a single large liquidation

Negative

• Ongoing disposals (multiple sales in July and October 2025) could modestly increase free float
• Aggregate market value of proposed sale $156,222 is material at the transaction level for the seller’s position

Insights

Equity Transactions Analyst

Planned brokered sale of insider-held Class A shares with recent small-block dispositions.

The filing discloses a proposed sale of 8,679 Class A shares via Raymond James on 10/06/2025 with an aggregate market value of $156,222.00. The seller originally acquired 75,176 shares on 07/02/2021, indicating these are previously held shares moving through an authorized Rule 144 process.

Recent transfers show four sales totaling 6,966 shares and $127,501.00 in gross proceeds across July and October 2025, which demonstrates ongoing, incremental disposals rather than a single large block. Watch whether future Form 144 filings or Form 4s report continued systematic sales over the next 30-90 days, as repeated sales could modestly increase public float and trading volume.
