A reason, or THE reason? My opinion is there was a few things and FDA is top of the list. We might never know, but unless management comes out and says "this is the reason" we have never uplisted to Nasdaq then we all speculate. I'm not giving approval for a reverse split of my shares over speculation.
we shouldn't have to guess or speculate. The company should have told us why instead of all the bullshit they peddled. Stock options are doing just fine though
