Why it's interesting
In the UK market this year Pizza Express doubled down on efforts to launched new lines and partnerships.
These included the re-launch of its retail range, including the introduction of gluten-free pizzas in Sainsbury's, and a new partnership with O2 Priority that was "proving popular" with customers.
In May, Pizza Express also inked a deal with Deliveroo, signing up around 200 of its restaurants to deliver on the service by the end of July. This is around half of its total locations.
It also said its Firezza business was "progressing well" since it was acquired in February and plans to roll the pizza delivery group out beyond its current London heartland.
What the company said
Chief executive Richard Hodgson said:
This has been a more challenging year for the UK casual dining sector, with a more cautious consumer and a significant increase in new openings. However, the strength of our offer and the initiatives we have put in place, including in the rapidly growing home delivery market, stand us in good stead.
In addition, further international growth, especially in China, represents a significant opportunity for us. We have the benefit of a strong brand and resilient business model that has traded successfully for over 50 years, and we are confident that Pizza Express will deliver further progress in the year ahead.
