Grab saya overall revenue down since the coronavirus outbreak.

SINGAPORE, May 14 (Reuters) - Overall revenues of Southeast Asian firm Grab have dropped since the coronavirus pandemic began, dragged down by the core ride-hailing business, the company’s co-founder said on Thursday.

Tan Hooi Ling said the Softbank-backed private firm had seen an uptick in its food delivery business but its total revenue was “lower than it used to be pre-COVID”, referring to the respiratory disease caused by the virus.
The firm was preparing for “a potentially long winter”, and taking measures to be more efficient and conserve cash, Tan added.

Answer the question follow:
The entrepreneurial process comprises developing opportunities, gathering resources, and managing and building operations, all with the goal of creating value. An effective business model must generate revenues to cover operating costs in the foreseeable future. Eventually, a growing venture will also need to provide enough cash flow to cover planned expansion and reinvesment. Financial distress occurs when cash flow is insufficient to meet current liability obligations. Alleviating financial distress usually required restructuring operations and assets or restructuring loan interest and scheduled principal paymenta. Most of a venture;s value is achieved in the form of free cash flows generated during the latter part of the venture;s rapid growth stage and during the maturity stage.
