The AA PLC (LON:AA.) kept its reduced profit forecast for the year unchanged even though bad weather sparked a surge in breakdowns.
Roadside call-outs rose by 8% to 1.91mln in the half-year to July, which was much higher than expected and the ten-year average.
That meant higher costs, said the insurer, as it had to use third-party garages to deal with breakdowns.
AA membership dropped by 1% to 3.25mln, in part due to renewal price transparency rules.
Insurance did well, with the number of motor policies sold rising by 7% to 659,000, while the decline in home insurance slowed.
In February, the group cut its dividends and earnings expectations and unveiled a strategy to invest more into new technologies and roadside improvement.
Today, it said it was on-track to meet the reduced guidance of underlying profits [trading EBITDA] of between £335mln to £345mln for the year to next January.
