Which company owns MAC address prefix 9C:93:5C?

MAC address prefix 9C:93:5C is registered to Unisyue Technologies Co;LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:93:5C has a network interface built by Unisyue Technologies Co;LTD.

What is the OUI 9C:93:5C?

9C:93:5C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Unisyue Technologies Co;LTD. It covers every address from 9C:93:5C:00:00:00 to 9C:93:5C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-93-5C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:93:5C:00:00:00 that is 9C:93:5C — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.
