Zoom Video Communications (ZM 1.73%) delighted investors when it reported first-quarter results for fiscal 2020 after the market closed on Thursday.

In its first quarterly report as a public company, the videoconferencing specialist beat Wall Street's revenue and earnings estimates, and issued better-than-expected guidance.

Shares closed up 11.8% in after-hours trading on Thursday, which bodes well for a robust performance on Friday. Since the company's initial public offering (IPO) in mid-April, Zoom stock has gained a whopping 121% through the regular trading session on Thursday -- and, while it's not a sure thing, investors can probably bet on that tally rising on Friday.

Here's an overview of Zoom Video's quarter, along with its guidance for second-quarter and full-year 2019, using five metrics.

1. Revenue soared 103%

Zoom's quarterly sales more than doubled year over year to $122.0 million, exceeding the $117.7 million that analysts were expecting. Growth was driven by the company winning new customers and by expanding the services it provides to existing customers.

Here's a look at key customer metrics:

2. Operating income flipped to positive from negative

Operating income came in at $1.6 million, up from a loss of $1.7 million in the year-ago period. Adjusted for one-time items, operating income landed at $8.2 million, up from an adjusted loss of $0.8 million in the first quarter of last year.

Operating margin was 1.3% and adjusted operating margin was 6.7%.

3. Earnings also turned positive from negative

Net income was $0.2 million, or $0.00 per share, compared to a net loss of $1.3 million, or $0.02 per share, in the year-ago quarter. Adjusted for one-time items, net income came in at $8.9 million, or $0.03 per share, up from a net loss of $0.5 million, or $0.00 per share, in the first quarter of last year.

Wall Street had been looking for break-even adjusted earnings per share (EPS), so Zoom easily surpassed the profit expectation.

4. Operating cash flow rocketed nearly 700% and FCF turned positive

Operating cash flow soared 693% year over year to $22.2 million and free cash flow (FCF) was positive $15.3 million, compared to negative $1.1 million in the year-ago period.

5. A sunnier-than-expected outlook for Q2 and full-year fiscal 2020

For the second quarter of fiscal 2020, Zoom Video guided for revenue between $129 million and $130 million, which, at the midpoint, represents 6.1% sequential growth. It expects Q2 adjusted EPS of $0.01 to $0.02. Wall Street had been modeling for break-even EPS on revenue of $123.3 million.

For the full year, the company projects sales in the range of $535 million to $540 million and adjusted EPS of $0.02 to $0.03. The Street has been anticipating full-year revenue of $525.9 million. (Going into the earnings report, there was no consensus estimate for full-year earnings.)

For a fast-growing, newly public company, revenue growth is usually more important than showing profits because such companies often plow money into initiatives aimed at rapidly scaling their business. That said, Zoom has a relatively rare distinction among technology IPOs of being profitable on a reported basis in its most recent fiscal year preceding going public.

CEO Eric Yuan commented on this topic in the earnings release:

In our first quarter as a public company, strong execution and expanding adoption of Zoom's video-first unified communications platform drove total revenue growth of 103% year-over-year. While we remain focused on strong [revenue] growth, we are also pleased that our highly efficient business model and disciplined investment approach contributed to positive non-GAAP [adjusted] profitability and free cash flow.

The bottom line

In short, Zoom Video Communications had a great quarter, with the company forecasting more good times on the horizon.

With cash and cash equivalents of $737.7 million at the end of the quarter, the company has plenty of money to fund growth.
