Deliveroo said it had achieved the twin milestones of positive net profit and free cash flow in the first half as demand from customers stabilised, sending its shares up 9% on Thursday.
Chief Executive Will Shu, who co-founded the business in 2013, said the performance overall was «really strong».
«We are improving profitability whilst we're still growing,» he said. «Orders returned to year-on-year growth and GTV (gross transaction value) momentum is good.»
The group, which has 662 million pounds ($841 million) of cash, said it would buy back 150 million pounds of stock.
Shares in Deliveroo, which competes with Uber Eats and Just Eat Takeaway, rose 9% to 139 pence.
Shu said consumer sentiment was more stable, although it would be a stretch to call it positive. «We're cautiously optimistic, we see less headwinds than we did before,» he said.
He said Deliveroo had improved its loyalty programme, adding a 10% credit award on orders over 30 pounds for its Plus Gold members and introducing a Plus Diamond for its top customers, who would be able to access exclusive restaurants.
«Plus customers are much more engaged on our platform than non-Plus customers, and Plus is over 40% of global order volume now,» he said.
Deliveroo upgraded its forecast for full-year core earnings to the upper half of 110 million to 130 million pounds range after reporting a better-than-expected 57% rise to 61.7 million pounds in the first half.
It reported net profit of 1.3 million pounds ($1.65 million), compared to an 83 million pounds
