Atome said it was working with a syndicate of investors to fully use the accordion feature of the three-year term loan facility that could boost the total amount to $100 million.

In a statement, Atome did not disclose the size of the financial commitment from EvolutionX, nor the identity of the group of investors involved in the syndicate.
