The company said the flour milling industry has been plagued with over capacity and volatile pricing in recent years.
However, a poor UK wheat harvest in 2012 has meant a greater need for imported grains which has helped Carr's, given the dockside location of its mills at Kirkcaldy, Fife, and Silloth, Cumbria.
It said another low volume harvest across 2013 is expected, meaning further reliance on overseas wheat.
The Scottish operation had also benefited from the closure of a Hovis mill on Dunaskin Street in Glasgow earlier this year, which helped to ease capacity pressure.
A new £17 million flour mill, the first to be built in Scotland in more than three decades, remains on track to open in Kirkcaldy during September.
Carr's said: "The planned significant efficiencies and improvements in operating margins [will come through next year]."
Analysts at Investec kept their predictions for this year unchanged, but added: "We still anticipate profit progress next year as the new mill drives flour milling returns back to more acceptable levels."
The weather also provided a boost to the agriculture division, which includes Ayr-based animal nutrition business Scotmin, at Carr's with cold and wet conditions in the spring saw a high level of sales of animal health products and feed blocks, particularly in the US, UK, mainland Europe and New Zealand.
