Nasdaq-listed shares of Zoom Video Communications, Inc., the video telephony and online chat company, are expected to open Tuesday up 7.65% from their Monday close of $409.66 - which was a 9.7% increase from its opening price that day.

The price rise was a result of the San Jose-based outfit saying it expected fiscal first quarter revenue of between $900 million and $905 million. Its estimate outstripped an analysts' consensus of $829.2 million, according to IBES Refinitiv data.

Eric Yuan, founder and chief executive officer of Zoom, said the firm was "well positioned for strong growth" in the coming year.

Zoom's share price has lost about 18% since news of the first vaccine breakthrough in early November. Zoom's share price had risen 13.8% from January to now as a result of workers and others forced to remain at home as a result of the coronavirus pandemic.

Zoom Video Communications reported better-than-expected fiscal fourth quarter earnings late Monday after the market had closed. The company also provided guidance stronger than analysts had expected.

The company's fiscal fourth quarter results posted late Monday showed revenue was up more than four times to $882.5 million from $188.25 million in the same period last year.

The figure beat average analysts' expectations of $811.8 million for the quarter. Adjusted earnings were $1.22 per share, beating Wall Street's estimates of $0.79 a share for the period.

Its latest quarter continues the trend of earnings growth for the company following the emergence of the coronavirus. Zoom said the trend was likely to continue through the next quarters as the pandemic continued to place office life on hold.

Zoom said it had acquired more than 1 million new paying users for its Zoom phone service. Zoom said it added 467,100 customers at the end of the fiscal fourth quarter.

Zoom's chief financial officer Kelly Steckelberg said that the company lost fewer customers over the past quarter when seasonal audio usage was expected to decline as a result of holidays. She said the company expected its churn rates to remain elevated in the coming quarters.

According to its latest earnings, the company ended the quarter with $4.24 billion in cash, marketable securities and cash equivalents. This was higher than the $1.87 billion it reported in the previous quarter.

Steckelberg said that the company was considering new acquisitions while it still had cash to spend. She said the company hadn't found the "right match" yet - but it was actively looking for one.

Some market participants are concerned about a possible slowdown in subscriber growth as world economies open up as more people get vaccinated.
