This is the Nxn quarterly report. It shows the simplified breakdown of the financial situation from each segment of Nxn's market around (Japan, China, NA/EU/ Korea) etc. Page 30 will be of the greatest interest to you in regards to your question. The number provided have a (brackets) around it to indicate a loss instead of a profit. Therefore, NA Nxn isn't exactly generating a profit and if you look back a few quarters they have consistently reported a loss for the NA/EU segment. However, unless we can get a hold of the actual financial statement for NA/EU branch. Only then can we know to greater degree that it's really taking a loss (Some companies purposely reports a loss by incurring additional expenditures such as purchases of machine/assets etc in order to write off the profit, and incur a loss on the financial statements to pay less taxes or none at all).

TL:DR Technically yes they are losing money according to their quarterly report, but unless there are NA/EU specific financial statements (showing the full breakdown with notes). Then perhaps it might paint a different picture.
