What happened

Shares of Twilio (NYSE:TWLO) gained 27.9% in the month of May, according to data from S&P Global Market Intelligence, after the cloud communications platform specialist announced stronger-than-expected quarterly results.

The bulk of Twilio's gains last month came on May 8, the day after it told investors that first-quarter revenue increased 48% year over year to $129 million, which translated to an adjusted net loss of $0.04 per share. Analysts, on average, were expecting a wider net loss of $0.07 per share on revenue of $116 million.

So what

Twilio's active customer accounts also maintained a torrid pace of growth, climbing nearly 33% year over year to 53,985 by the end of the quarter.

"We are honored that a growing list of companies around the world are placing their trust in Twilio," said Twilio co-founder and CEO Jeff Lawson. "Our first quarter results exhibited broad-based strength across multiple areas of our business, especially with continued expansion with existing customers."

Now what

If that wasn't enough, Twilio told investors to expect full-year 2018 revenue to arrive in the range of $538 million to $544 million, with an adjusted loss per share of $0.10 to $0.07. Here again, both ranges were comfortably ahead of consensus estimates calling for a wider 2018 loss of $0.12 per share on revenue of $512 million. 

In the end, there was nothing not to love about Twilio's strong start to the year, and it should be no surprise to see the stock once again flirting with the all-time highs it set shortly after its late-2015 IPO.
