"The fourth quarter should see significant growth compared to the third quarter," it added, without elaborating.
Foxconn, formally called Hon Hai Precision Industry Co Ltd, said revenue last month reached T$660.7 billion ($20.46 billion), down 19.7% year-on-year but soaring 60.1% from August.
Revenue in its smart consumer electronics products, including smartphones, saw strong growth month-on-month "due to new product launches in September", Foxconn said.
Foxconn is the world's biggest iPhone assembler, but has been trying to diversify into electric vehicles.
It added that September year-on-year revenue for cloud and networking products, which includes servers, declined due to "conservative customer pull-in".
