BOSTON, June 16, 2022 — Abacus Insights, a leader in data management and interoperability solutions

platform to drive efficiency in their business which further lowers costs for their members. We are
proud to partner with MultiPlan given their leadership position in data and analytics serving nearly every
payor in the country. MultiPlan shares our belief that better data means better care, and this
investment represents an important step in achieving our goal to make healthcare more personalized
