Inovalon Results Presentation Deck

2018 Revenue Guidance Bridge Inovalon continues to transition its business to an increasingly subscription-based cloud- based platform model. The Company's advancing capabilities and technologies continue to be positively recognized in the marketplace, in addition to the in-year contribution from the ABILITY acquisition. At the same time, external market forces related to the ACA are a short-term opposing force in 2018.
