Rackspace filed with the U.S. Securities and Exchange Commission for an initial public offering (IPO) of its common stock on the Nasdaq Global Select Market under the RXT ticker.

While the details of the Rackspace IPO have not been made public, an earlier Reuters report suggests the public offering could value the cloud services company at more than $10 billion.

The announcement puts to rest months of rumors surrounding Rackspace's return to the public market. The company went private in 2016 in a $4.3 billion deal led by Apollo Global Management.

According to Reuters, rising stock prices of Rackspace peers, including Fastly and Datadog, prompted Apollo to register Rackspace for an IPO.

The company has changed a great deal since it was acquired by Apollo. While Rackspace got its start building managed private clouds based on OpenStack, Microsoft, and VMware, among others, it moved into managed cloud services shortly after the acquisition.

Rackspace has also since acquired TriCore Solutions, Datapipe, and cloud-native consulting and managed services firm Onica. It now provides managed services to companies that want to move their workloads to public clouds including Amazon Web Services (AWS), Microsoft Azure, and Google including managed Kubernetes, application and data migration and integration, consulting, and multi-cloud security.
