They did indeed say they "believed" they weren't.
AMD Processor Security | AMDGPZ Variant 3 (Rogue Data Cache Load or Meltdown) is not applicable to AMD processors
We believe AMD processors are not susceptible due to our use of privilege level protections within paging architecture and no mitigation is required.
They said in the same link that they (like everyone else) are vulnerable to Spectre though. Which is the worse one.
