"Net Income for Q2 2017 was $413,468, or 0.04 per share, compared to $829,896, or 0.10 per share for Q2 2016. This decrease was due to increase sales and marketing expenses in the second quarter, loss on disposal of assets and one time litigation expenses. "
What you're missing here is that Cemtrex streamlines operations of companies that it acquires in an effort to improve their profitability. For instance, Rob Group was once about twice the size it is now, but found itself in bankruptcy. Cemtrex has shifted Rob's emphasis to higher tech operations. I believe there has been a similar streamlining going on with Periscope. Comparing revenues including pro forma numbers is really off base.
