Grab, which has operations across eight countries and more than 400 cities in a region of 650 million people, said it expects to report group-level adjusted net sales of $2.1 billion to $2.2 billion, versus an expected $2.3 billion announced in April.

It also forecast a group-level adjusted EBITDA loss of $0.7 billion to $0.9 billion for this year compared with a previously projected EBTIDA loss of $0.6 billion.

"Grab's full-year 2021 outlook anticipates an extension of partial and complete lockdowns throughout several countries where Grab operates as a result of the continuing spread of COVID-19," the company said.

Grab's second-quarter adjusted net sales jumped 92% to $550 million while its adjusted EBITDA loss rose 4% to $214 million.

Grab said its quarterly total gross merchandise value (GMV), a metric used to measure transaction volumes, jumped 62% to a record $3.9 billion. GMV for deliveries grew 58% to $2.1 billion, while GMV for mobility rose 93% to $685 million.

"Our deliveries business continues to outperform and is growing rapidly, with the addition of new offerings such as GrabMart and GrabSupermarket, and we expect to continue investing heavily in this segment," Peter Oey, Grab's chief financial officer, said.
