NOTE11 –LOSS PER SHARE

Basic and diluted net income (loss) per common share is determined by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. For the periods where there is a net loss, stock options, warrants, and RSUs have been excluded from the calculation of diluted net loss per common share because their effect would be anti-dilutive. Consequently, the weighted average number of shares of Common Stock used to calculate both basic and diluted net loss per common share is the same for the reported periods.

As of* September 30, 2025*, the Company had 609,385 RSUs,5,299,879 prefunded warrants, and 6,091,346 warrants, all exercisable for shares of Common Stock.
