Acquisitions In December 2021, we completed the acquisition of two companies, Neustar and Sontiq, which we anticipate will significantly enhance our offerings. Neustar, a premier identity resolution company with leading solutions in Marketing, Fraud and Communications, enables customers to build connected consumer experiences by combining decision analytics with real-time identity resolution services driven by its OneID™ platform. Sontiq provides solutions, including identity monitoring, restoration, and response products and services, to empower consumers and businesses to proactively protect against identity theft and cyber threats. We will incorporate the impact of these acquisitions in our 2022 Sustainability Report, but their impact is not reflected herein unless expressly specified. In addition, TransUnion completed a divestiture of its Healthcare business on December 17, 2021; the metrics reported herein reflect the divesture.
