The struggling electronics giant's nine-month net loss of 623.83 billion yen ($6.77 billion) nearly doubled its year-earlier shortfall, while sales slipped 8.8 percent to 5.44 trillion yen, owing to weak flat-panel television sales.
However, the company said it posted an operating profit of 121.95 billion yen in the same period, adding that the positive result was due "mainly to fixed cost reductions and streamlining material costs".
Panasonic, like rivals Sony and Sharp has seen sales slump on the back of the global slowdown while it also took on huge restructuring costs, which contributed heavily to its bleeding bottom line.
Also Friday Sharp reported that its net loss in the April-December period had doubled to $4.6 billion.
