In just a few hours, Zoom Video Communications Inc. Chief Executive Officer Eric Yuan got $4.2 billion richer.

Shares of his virtual-meeting company surged as much as 26% to $410 in late U.S. trading as it reported a jump in quarterly revenue and suggested the explosive growth will continue. Should the stock maintain such a gain on Tuesday, Yuan’s fortune would surpass $20 billion.

Zoom has been one of the clearest beneficiaries of the coronavirus pandemic, with businesses and educational institutions turning to the service to work and teach remotely.
