Hon Hai also declined to comment.
Sharp was once a highly profitable manufacturer of TVs and a favored screen supplier to Apple and others, but it has come under heavy pricing pressure from South Korean rivals.
In May, it sought a bailout of roughly $1.9 billion from banks and promised to cut 5,000 jobs, or 10 percent of its staff.
Rumors of a possible tie-up of Sharp with Hon Hai as well as cash injections from other entities had emerged last month.
Tie-up talks between Hon Hai and Sharp fell through in 2012 after the Japanese company baulked at demands that it said would have given the Taiwanese firm too much control.
