Insights

Securities Analyst

TL;DR: Insider plans to sell 1,760 shares acquired by option exercise; size is immaterial relative to outstanding shares.

The filing documents a Rule 144 notice for 1,760 shares valued at $2,467,687.38 to be sold on 08/26/2025 via Morgan Stanley Smith Barney LLC. The shares were acquired the same day by exercising registered options (820 and 940 shares) and paid in cash. Relative to 56,350,285 shares outstanding, this sale represents roughly 0.003% of the float, which is unlikely to be market-moving. The filer also affirms absence of undisclosed material adverse information.
