TDK Corp. said Thursday its group net profit in the April-June quarter was up 79 percent from a year earlier.
The electronics device maker attributed the profit growth to the yen's fall against the dollar and euro.
In the period through June 30, TDK's consolidated net profit amounted to 2.16 billion yen, boosting its per-share net profit to 16.27 yen from 9.7 yen a year before.
Pretax profit in the three-month period grew 28.8 percent to 3.3 billion yen, on sales of 148.71 billion yen, up 6 percent.
The yen's value depreciated 4 percent to an average of 127 to the dollar, and 9 percent to 117 to the euro during the period, the company said.
The declines against the two currencies gave TDK a combined windfall exchange gain of 4.2 billion yen in terms of consolidated sales, it said.
