Sharp's share price plunged to four-decade lows in August when it reported a quarterly loss of about $1.76 billion, prompting Standard & Poor's to cut its credit rating to junk status.
The maker of Aquos-brand electronics has struggled amid fierce overseas competition and a strong yen, with the bigger-than-expected loss tied largely to writedowns of its LCD panel inventories amid weak demand and heavy restructuring costs, the Nikkei said.
A Sharp statement responding to the Nikkei story said only that the company had not officially announced any changes to its earlier earnings projections. Its half-year results are due on November 1.
Sharp, which has seen its mainstay television, liquid crystal display and solar panel products struggle, has promised to return to the black in the next fiscal year starting in April.
However, the weak results were likely to prompt a revision to its projection of a 250 billion yen loss in the current fiscal year to March 2013.
In August, Sharp said it would slash 5,000 jobs worldwide with later reports saying it would shed 19 percent of its 57,000-strong global workforce, by the end of March 2014.
The firm has also announced wage cuts for thousands of employees from the factory floor to the executive boardroom and the sale of real-estate to shore up its bleeding balance sheet.
An expected capital injection from Taiwan's Hon Hai Precision, which makes Apple gadgets in China, has stalled, with US chip giant Intel emerging as a possible tie-up partner for the Japanese firm.
