No, it isn't really a coincidence. Riviera Tool Company (RIVT) had been in business for a long time. By 2007 they had serious financial problems, and defaulted on their debt. Their principal creditor, Laurus Master Fund, resolved that situation by taking the company's assets. The company delisted from the AMEX.
Laurus then sold those assets to a group of Canadian investors. Remarkably, those investors wanted to keep the the business going. They created a company called Riviera Tool Acquisition LLC, or Riviera Tool LLC, and rehired the old employees. The new entity has been operational ever since, and has been doing tool and die work for Tesla for some time.
But the deal didn't include the public shell. RIVT continued to trade as a zombie ticker, and finally… well, you know what happened.
