SAN RAMON, Calif. — Zoom’s videoconferencing service is deepening its integral role in life during the pandemic as tens of thousands more businesses and other users pay for subscriptions to get more control over their virtual meetings.

The surge in paying customers enabled Zoom to hail another quarter of explosive growth. The company on Monday reported that its revenue for the May-July period more than quadrupled from the same time last year to $663.5 million, boosted by a steadily rising number of users converting from the free to paid version of Zoom’s service.

Zoom finished its fiscal second quarter with 370,200 customers with at least 10 employees, a gain of about 105,000 customers from the end of April. Just a year ago, Zoom only had 66,300 customers with at least 10 employees paying for subscriptions.

All that money pouring in helped Zoom earn nearly $186 million, or 66 cents per share, during its latest quarter, up from just $5.5 million at the same time last year.

“Organizations are shifting from addressing their immediate business continuity needs to supporting a future of working anywhere, learning anywhere, and connecting anywhere on Zoom’s video-first platform,” Zoom CEO Eric Yuan said.

Investors have latched on to Zoom too. After having already increased by fivefold so far this year, Zoom’s stock price is poised to to climb to even loftier heights. The exuberant response to its quarterly report lifted the company’s shares by nearly 23% in Monday’s extended trading.

If the stock follows a similar arc during Tuesday’s regular trading session, Zoom for the first time will boast a market value of more than $100 billion — exceeding the combined value of two storied automakers, General Motors and Ford, and two major airlines, American and United.

Back in early June, Zoom warned that it might suffer a wave of subscriber cancellations during the second half of the year if efforts to contain the spread of the novel coronavirus allowed more workers to return to offices.
