Denso Corp., bolstered by rebounding automaker production in Asia and North America, closed its fiscal year that ended March 31 with net income of 143 billion yen ($1.7 billion), up 95 percent from a year earlier.
Sales for the world's largest auto parts supplier rose 5 percent to $37.7 billion.
Denso said the March 11 Japan earthquake only had a minor impact on the company's results for the fiscal year just ended, but made it impossible to issue a forecast for the current fiscal year.
"We will announce the forecast as soon as we assess the impact," CEO Nobuaki Katoh said in a statement. "For the time being, the recovery from the earthquake will be our top priority."
In the year just ended, Denso's first-half results were boosted by a Japanese government incentive program akin to the cash-for-clunkers program in the United States in 2009. In the second half, rising exports from Japan, by far Denso's largest market, helped to offset the end of that government program.
Denso has been on a tear since its fiscal year ending March 31, 2009, when it tallied a net loss of $903.8 million.
In the fiscal year just ended, Denso's North American operating profits more than tripledto $305 million, a result of ramped-up vehicle production and increased sales to General Motors, Ford Motor Co. and Chrysler Group. Sales rose 13 percent to $6.4 billion.
In Europe, Denso's sales fell 2 percent to $4.8 billion, due to currency exchange losses. But an increase in production volume of European automakers led to a 2 percent gain in operating profit, to $131.4 million.
In Japan, sales rose 4 percent to $25.4 billion. Increasing production volumes and cost reduction efforts resulted in an operating income of $762.3 million, up 55 percent.
