TL;DR Routine beneficial holder sale notification for ANAB: modest-sized sale disclosed via Form 144.

The filing documents a proposed sale under Rule 144 of 8,240 common shares valued at $238,960, to be executed through Morgan Stanley Smith Barney on NASDAQ around 09/30/2025.

The notice indicates the seller complied with Rule 144 disclosure requirements by identifying acquisition dates and payment methods: restricted stock paid at grant and option shares paid in cash.
