Yes, compatible - the wall mount supports the VESA pattern and weight of your TV. The wall mount is designed for screen sizes 32-84" and load capacities of up to 60 kg and supports VESA standards from 200×200 to 600×400 mm; it therefore fits televisions with a VESA pattern and weight within these values (max. wall distance 51 cm, tiltable and swivelling).
I am not quite sure about the exact VESA pattern and weight of your Sharp 43HL4265E; please check the VESA hole pattern (e.g. 200×200 mm) and weight of the device and compare it with the specifications mentioned above.
