Zoom Video Communications (ZM 0.05%) reported powerful fiscal fourth-quarter and full-year 2021 results on Monday after the market close. In the quarter, which ended on Jan. 31, the videoconferencing specialist's business continued to get a brisk tailwind from the COVID-19 pandemic, which has driven a surge in the number of people working, learning, and socializing from home. 

Shares (which went public in April 2019) are up 8.4% in Monday's after-hours trading session, as of 5:46 p.m. EST. We can attribute the market's delight to quarterly revenue and earnings crushing the Wall Street consensus estimates, and fiscal Q1 2022 guidance for both the top and bottom lines also easily surpassing analysts' expectations.

Below is an overview of Zoom's quarter, along with its outlook for first-quarter and full-year 2022.

1. Revenue jumped 369%

Zoom's fourth-quarter sales soared 369% year over year to $882.5 million. This result sped by the $811.8 million analysts were expecting, and the company's guidance of $806 million to $811 million. Growth was driven by the addition of new customers and expansion of the services the company provides to existing customers.

For context, in the prior two quarters, Zoom's revenue surged 367% (Q3) and 355% (Q2) year over year. For the full fiscal year, revenue rocketed 326% year over year to $2.65 billion.
