Help needed,

I have the following values in cells A1 = H, B1 = 3 and C1 = 56%.

I need an array formula to obtain the following result if the cell values meet the following criteria.

If A1 cell value is H and B1 cell value is equal to/or lower than 4 amd C1 cell value is equal to/or greater than 55% then I need the cell value returned to be -1.25.

Thanks in advance for your help.
