Which company owns MAC address prefix 38:0A:0A?

MAC address prefix 38:0A:0A is registered to Sky-City Communication and Electronics Limited Company in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 38:0A:0A has a network interface built by Sky-City Communication and Electronics Limited Company.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 38:0A:0A:00:00:00 that is 38:0A:0A — 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.
