The company, which sells software to analyze large volumes of unstructured data generated by machines, saw sales rise 50% year-over-year to $86 million. Splunk also reported a $0.04 adjusted net loss per share, an improvement over the $0.06 loss per share reported in the year-ago period.

Analysts were looking for a $0.06 loss per share on sales of $81 million. Splunk exceeded both targets.

Splunk generated $14.7 million of free cash flows in the first quarter, down from $18.6 million in the corresponding quarter in the previous year. Stock-based compensation expenses, which were excluded from non-GAAP earnings figures, more than tripled year over year to land at $43.2 million.

Looking ahead, management issued revenue guidance above the current Street view for the second quarter. Full-year revenue targets were raised by 1.5%, and now align closely with analyst projections.

"We are accelerating our investments in core technologies, cloud services and market specific solutions to better serve our global customers," said Splunk CEO Godfrey Sullivan in a prepared statement.
