If my understanding is correct, annual reconstitution occurs in December, based upon market data "through the end of October" and SEC filings through the end of November.
Based upon shares outstanding disclosed in the Company's Q3 filing the share price needed to be $6.41 to meet the eligibility criterion of a $200 million capitalisation. We closed on October 31 on $6.39.
I've never been sure if there's any difference between "through the end of" and "at the end of". If the two are effectively synonymous in this instance that would be my best guess for our non-inclusion.
