The miller also deals in bottled water, ethanol and power generation in a diversification plan aimed at cutting reliance on sugar.
Sales from ethanol increased to Sh488 million in the first half from Sh50 million in the same period a year earlier while the water business grew revenues 40 per cent to Sh14 million.
Mumias says the power division saw sales drop 46 per cent without giving the actual revenues.
Its share price at the Nairobi Securities Exchange has dropped 26 per cent over the past six months to Sh3.00 on Thursday.
The miller recently reduced the price at which it buys cane from Sh3,825 per tonne to Sh3,385.
Its rivals have also reduced their prices by between 11.5 per cent and 27 per cent in what is seen as a signal of increased cane supply.
