Financial Analyst

TL;DR: Routine Form 144 filing for a proposed sale of 12,000 founder shares; disclosure is clear and the position is small versus total outstanding.

The filing documents a proposed sale of 12,000 common shares via J.P. Morgan with an aggregate market value of $2,982,600 and an approximate sale date of 08/13/2025. The shares were acquired as founder stock on 06/22/2004 and the filer reports no sales in the past three months.
