Komatsu, the world number two construction equipment maker, saw first-quarter operating profit for the three months ending June this year leapt 76% to 52.4bn yen ($472 million) from the same period a year earlier.
Consolidated net sales totaled 561.2bn yen, up 44.2% from the corresponding period a year ago.
In a financial statement Komatsu said: “In the construction, mining and utility equipment business, sales expanded sharply from the corresponding period a year ago, supported by the steadfast capturing of demand in China, Indonesia and many other countries as well as the positive effects of adding Joy Global (currently, Komatsu Mining Corp.), a leading US manufacturer of mining equipment. Komatsu completed the acquisition of Joy Global Inc. in April this year."
