The electrical goods retailer said it was keeping its options, which include a possible sale of the struggling chain, open.
"Comet turnaround plan underway while continuing to examine other strategic alternatives," the firm said.
In June, Kesa said it was looking at a range of options for Comet, including a disposal or formation of a joint venture, while at the same time pressing ahead with a turnaround plan which included selling weaker shops and focussing on profitable ranges like small appliances.
Kesa also posted a further deterioration in trading at Comet for the three months to July 31, its fiscal first-quarter.
Sales at Comet stores open over a year slumped 22.1 per cent, although gross margin increased 80 basis points.
The sales decline compared with analyst forecasts of a fall of 18-25 per cent and partly reflected a tough World Cup football comparative with the same period last year.
Like-for-like sales at the group's Darty business in France fell 3.7 per cent, better than analyst forecasts of a fall of 4.2-6 per cent. Gross margin was up 10 basis points.
