Atlus has posted a public notice for their final fourth quarter earnings, and the company is reporting a net loss of 570 Million Yen, which is about $5.12 Million in USD according to Social Game Info. The loss comes in despite significant sales numbers on Persona 5 in Asia, though the figures for the US and Europe don't count as the game came out after the conclusion of the company's fiscal year 2017, which ended on March 31st, 2017.
There was no official reason given for the massive loss, but at Persona Central points out, the company launched a third creative studio during the Fiscal Year as well as plans for business expansion and an increase in recruitment.
Atlus is by no means in trouble, and with the performance of Persona 5 in North America and Europe, it is highly likely that the company's fiscal year 2018 will look much better.
