What ever the starting price was at the start of the comp, it will be consolidated at the shares ratio.
So if a stock was $0.100 at the start of the comp, then mid month had a 25:1 consolidation. Obviously the price of the stock is going to be trading in/around 2.50.
The comp will see the share price as a jump of 2500% and stay in tune with the stock price until the end of the month until admin adjust the stocks price to find the "real" winner.
If at the end of the month the stock is trading at 2.60, the consolidated price will start at 2.50, so your stock rise would only be 4%.
