NEC Corp lowered its forecast of group sales for the year to March to $34,850m from the $35,520m guess in May, but left its group profit forecasts unchanged; it also said that it is likely to exceed its originally planned investment in semiconductor facilities for the current fiscal year to meet brisk demand for memory chips – NEC is considering raising capital spending on chip factories in the second half of the fiscal year, so that it reaches $768m, up from the $672m it had planned earlier; the expansion will probably be at its plants in Roseville, California, and Hiroshima, western Japan, but the company says that it will not make a final decision till October.
