Nasdaq Conditional Approval
"Conditional" probably means conditional on SEC first approving EXRO's Form F40 registration (declaring it "effective"). This is the earliest date that EXRO can commence trading on the Nasdaq. Notices of Effectiveness are listed on EDGAR at https://www.sec.gov/cgi-bin/browse-edgar?action=geteffect This list is updated daily by SEC.
I don't believe that EXRO will execute until its can achieve a respectable share price. Its SP yesterday was below the Nasdaq $1USD 'delisting' price.
Canadian companies uplist to Nasdaq to increase visibility and to gain access to the US capital markets. Limping in with a minimal SP is not conducive to attracting US institutional investors IMO.
