Domino's Pizza Group PLC said Thursday that like-for-like sales for the third quarter of the year rose 8.8% and that it expects to meet full-year expectations.

The company added that it has experienced some impact from labor issues and food inflation, which it expects to continue into next year, but continues to take measures to maintain its supply chain levels and costs.

System sales--which includes both franchised and corporate stores to consumers in the U.K. & Ireland--for the 13 weeks ended Sept. 26 were 375.8 million pounds ($513.3 million) compared with GBP342.1 million, taking the total for the 39 weeks to GBP1.13 billion, compared with GBP971.0 million.

Domino's also said that it is hiring 8,000 new staff across the U.K. and Ireland.

"Trading remains in-line with our expectations, we are well placed as we gear up for our peak trading period and believe our strategy is working to create sustainable value for all our stakeholders," Chief Executive Dominic Paul said.

The company hasn't provided any figures for the year. However, consensus for adjusted pretax profit--one of the company's preferred metrics that strips out exceptional and other one-off items--is GBP112.7 million, taken from FactSet and based on six analysts' forecasts. This compares with GBP101.2 million for 2020.
