It will only affect OTC stocks that don't stay current with their filings. I have own LWLG for over 18 years. I cannot recall LWLG ever missing a filing. I think they filed for a extension once.
E*TRADE sent something similar... They just gave different interim timelines but the Sept. 28, 2021 deadline is SEC driven and was the same in the email I got too. It's not Lightwave specific but OTC stocks in general .
Thanks to all for the added info and suggestions! Sounds like this will not affect LWLG but couldn't hurt to open up another trading account as well just to hedge in general.
