(Adds updated valuation for Grab) SINGAPORE, Oct 22 (Reuters) - Singapore’s Grab, which has evolved from a ride-hailing app operator to offer services such as food delivery and insurance, said on Thursday its third-quarter group revenue had risen to more than 95% of pre-COVID-19 levels. “Our business recovery continues steadily, with Q3 group revenues climbing to over 95% of pre-COVID-19 levels,” Ming Maa, president of Grab, said in an emailed newsletter update on the company’s business. Softbank-backed Grab in June laid off around 360 employees or almost 5% of its headcount, after slashing discretionary spending. The company’s key ride-hailing business had been hit hard as countries, including biggest market Indonesia, implemented lockdown measures. Grab, Southeast Asia"s biggest start-up, is now valued at over $15 billion, according to a source familiar with the matter, up from a previous estimated valuation of over $14 billion.

Grab, which is yet to turn profitable, had received a $200 million investment from South Korean private equity firm STIC Investments, Maa said.
