(3) The price per share indicated reflects solely the application of the applicable reverse split ratio to the closing price of the common stock on April 15, 2026.

After the effective date of a Reverse Split, our common stock would have a new committee on uniform securities identification procedures (CUSIP) number, a number used to identify our common stock.

Our common stock is currently registered under Section 12(b) of the Exchange Act, and we are subject to the periodic reporting and other requirements of the Exchange Act. A Reverse Split will not affect the registration of our common stock under the Exchange Act. Our common stock would continue to be reported on Nasdaq under the symbol “GNPX,” although it is likely that Nasdaq would add the letter “D” to the end of the trading symbol for a period of twenty trading days after the effective date of a Reverse Split to indicate that a Reverse Split had occurred.
