Following the blockbuster quarter, Zoom boosted its guidance.
Medium and large companies make up the bulk of Zoom's paying clients.
The software maker reported on Monday that sales jumped 355 per cent to US$663.5 million in the three months through July 31 - the second-largest surge among Nasdaq 100 Index members last quarter, only behind biotech firm Moderna, data compiled by Bloomberg shows.
The company said that net income attributable to common stockholders rose to $185.7m, or 63 cents per share, from $5.5m, or two cents per share, a year earlier. Zoom said sales will be as much as $2.39-billion in the fiscal year ending in January, meaning revenue would nearly quadruple in just one year.
"As remote work trends have accelerated during the pandemic, organizations have moved beyond addressing immediate business continuity needs to actively redefining and embracing new approaches to support a future of working anywhere, learning anywhere, and connecting anywhere", Zoom CEO Eric Yuansaid Monday in an earnings call.
Shares of Zoom skyrocketed as much as 38% in premarket trading Tuesday.
It leaves Zoom closing in on a valuation of $100bn, more than corporate giants such as General Motors and Ford.
Zoom cautioned in early June that significant numbers of customers could cancel subscriptions if workers returned in droves to offices as lockdown restrictions eased.
But the ongoing outbreak has prompted many major employers to keep their offices closed through the rest of the year and possibility into next summer, a development that could propel Zoom to even greater heights.
The founder of the San Jose, California-based company, whose net worth is mostly made up of his more than 50 million Zoom shares, is one of the biggest gainers this year.
In a show of confidence, Zoom raised its revenue projection for its fiscal year ending in January to almost $2.4 billion, up from roughly $1.8 billion that the San Jose, California, company predicted in early June. Hackers and others exploited security weaknesses to intrude on private meetings, prompting some users to abandon the service. Although the outage only lasted a few hours, the breakdown heightened awareness about society's increasing reliance on Zoom.
