A small RS like 1 for 5 is not that big of deal, especially if it allows you to uplist your company to a major board. By the time they do the RS (as they mentioned they would at the Shareholder meeting) they will be out of the pinks and on OTCBB. The pps would be at $1 or higher, so a share buyback program at that level is not cost effective.
Don't fear a 1 for 5 RS. Rather, fear the 1 for 1000 share RS of some typical diluting pink stock scam, which NanoTeck is not in that category.
