Yes, I believe this is the case.

In any event, IANA/ARIN and the other RIRs are the authority on who 
controls a given IP block, not Merit.

Your customer should contact ARIN with proof that the previous org 
still exists as a legal entity and they are the owners and have 
authority to change POC records, and then they should subsequently get 
the POC records updated, or if it doesn't, that it was sold/merged into 
a new org, and get the space assigned to a new OrgID.

The way I would verify a case like this, since the names are different, 
would be to email the Tech POC and confirm that they have authorized you 
to announce their space. If you get a positive reply from that, then 
combined with a signed LOA from your customer, that should be enough 
verification for both you and your transit carriers.

If you want to stick to your guns, you should inform your customer you 
were unable to verify that the IP space belongs to them, and for them to 
contact ARIN to fix the POC records associated with it.
