If you add up the Series D' Convertible Preferred Stock line you will get the 2,080,595. The note says that the preferred converted to common. It also shows some warrants appear to have been exercised. So on 7/15 looks like they owned 2.6m shares. They must have sold the stock that was exercised from the warrants.
