Donnelley Financial Solutions, Inc.
A provider of software and services that help public companies, mutual funds, and other regulated firms file their financial reports and handle investor communications. Its cloud-based tools include ActiveDisclosure, a platform for SEC and ESG reporting. The business began in 1983 as the financial unit of R.R. Donnelley & Sons, the Chicago printer founded by Richard Robert Donnelley in 1864, and was spun off as its own independent company in 2016. A fun relic of that heritage: the printing house's plant burned down in the Great Chicago Fire of 1871, yet the founder rebuilt it on credit.
