Vivint Solar’s parent Vivint Inc., itself owned by private-equity group Blackstone, has taken advantage of a relatively new US law that allows companies with annual revenues of less than $1bn to confidentially file IPO papers with the Securities and Exchange Commission, according to Reuters.

Reuters relied on unnamed “people familiar with the matter” for its story, adding that banks like Goldman Sachs have been brought on to help manage the flotation.

Vivint Solar trails only SolarCity in US residential rooftop installations, and the company has chalked up explosive growth since it was launched in 2011 by Vivint, one of the largest home automation and alarm companies in the US.
