Chief executive Jitse Groen said the group had added a record number of new restaurants and customers, with each customer ordering more on average than before.
He said: "Just Eat Takeaway.com is in the fortunate position to benefit from continuing tailwinds.
"The United Kingdom, Germany, Canada, the Netherlands, Australia, and Brazil are performing particularly strongly. Our businesses have healthy gross margins, and all our segments are adjusted EBITDA positive.
"On the back of the current momentum, we started an aggressive investment programme, which we believe will further strengthen our market positions. We are convinced that our order growth will remain strong for the remainder of the year."
The company still made a loss of e158 million, up on e27 million a year earlier, although it said that was due to one off costs relating to the mergers of Just Eat and Takeaway and the proposed takeover of another rival, Grubhub.
Groen has blazed an acquisition trail across Europe as it has fought to become the consolidator in a competitive field including rivalry from Deliveroo and Uber Eats.
He said the integration of Just Eat was on track, with the brands all operating with the same logo and migration onto the same European IT platform on track.
But he said he felt the brands under Just Eat had been starved of investment in recent years.
"We have embarked on an aggressive investment programme and will invest significantly in the United Kingdom, Canada, Australia, Italy, Spain, France and several other ex-Just Eat markets," he said.
In April this year it won final approval from UK competition authorities to takeover Just Eat for $7.6 billion and in June announced the proposed takeover of US-based Grubhub for £5.8 billion after a bidding battle with Uber.
