Halfords' annual results on Wednesday are a week late after auditor BDO requested more time to complete what the statement said were standard audit procedures.
The bike, car parts and maintenance group said it still expects to report an underlying profit within its previously guided range of £50mln to £60mln.
Guidance was reduced earlier in the year due to a shortage of car mechanics, a slippage in demand for higher-end items and a weaker tyre market.
Since then, Halfords has had a capital markets day when it outlined a target of doubling its pre-tax profit to £90-£110mln within three to four years with 75% of the improvement to come from self-help and cost-cutting.
