Dynasil (DYSL) de-registered from the SEC a few weeks ago, moving from the NASDAQ to OTC Pink. To file the de-reg they bought out all shareholders holding less than 8k shares for $1.15, dropping common outstanding by 16%. The company estimates a $900k annual savings from not filing with the SEC yet market cap has dropped by 35% from the day before they announced their intention. Seems like an overreaction to me.
