C&C noted that it expects to deliver net revenue of in the region of €870 million, in the six months to 31 August 2023.
This figure which is down almost 1% on the comparable prior year period, its latest financial results show.
Operating profit for the Bulmers owner is expected to be in the range of €29-€31 million.
Trading in first have for its own brands which included Five Lamps and Tennents, in Ireland and Scotland was 'encouraging', with net sales revenue for its branded business up almost 6% for the period.
Trading at the start of the year for C&C benefited from good weather, particularly in June, the company noted.
However poor weather in July and August combined with cost-of-living pressures, particularly in GB, resulted in a slowdown in the latter months of the period, it added.
'Difficult Market Backdrop'
Patrick McMahon, group chief executive officer, commented, “Set against a difficult market backdrop, we are pleased with the strength of the performance of our branded businesses in Ireland and Scotland in the period.
"We are particularly pleased with the progress we have made in restoring customer service levels following the ERP system implementation issues in our GB distribution business within our planned timeframe.
"Delivering outstanding service, winning back customers, continued business simplification and improved operating efficiency remain our top priorities and focus for the second half.”
The group’s process to recruit a new group chief financial officer is ongoing, C&C noted.
C&C will announce first half results on Thursday, 26 October 2023.
