Insights

Financial Analyst

TL;DR Routine insider sale of 1,800 shares disclosed; prior partial sales occurred in August and September 2025.

The Form 144 documents an intended market sale rather than an extraordinary corporate event. The shares were acquired via option exercise on 12/28/2022, indicating these are previously vested holdings being liquidated through a broker. Aggregate market value reported is 455,796, which relative to total shares outstanding of 38,999,129 is immaterial to company capitalization. For investors, this filing primarily signals insider liquidity rather than operational or financial change.
