IT management software company SolarWinds went public today on the New York Stock Exchange opening at $15.30 per share. That price was 2 percent above its initial offering price of $15.

The company offered 25 million shares using the ticker symbol “SWI.” At deadline, the company's stock price had declined to $14.95 per share giving it a market capitalization of $1.073 billion.

Yesterday, according to an SEC filing, the firm nearly halved the IPO, cutting the number of shares from 42 million to 25 million. This cut the price per share from the $17 to $19 range to a range $15 to $16.

SolarWinds was previously listed on the exchange, but was taken private in a $4.5 billion deal October 2015 by two private equity firms — Thoma Bravo and Silver Lake Partners.

According to SolarWinds CTO Joe Kim, when the company went private it was because it wanted to “broaden the horizon” and enter additional markets as well as attract new types of customers. Today, was the right time for the company to go public (again) because “we had accomplished some things that we wanted to.”

Going forward, he said, the company hopes to continue on this trajectory as a public company.

As a private company SolarWinds made multiple acquisitions. It acquired cloud-based log monitoring and log analytics software provider Loggly in January of this year. Loggly’s software-as-a-service (SaaS) log monitoring and analytics product was integrated into SolarWinds’ existing SaaS-based cloud monitoring systems. In July, it acquired threat monitoring service Trusted Metrics. SolarWinds intends to roll Trusted Metrics into a new security product called SolarWinds Threat Monitor once the purchase is complete. And in June 2016, it bought IT service management company Logicnow.

SolarWinds initially filed to re-list on the Exchange back in September with a maximum offer price of $500 million.
