Inovalon Results Presentation Deck

Adjusting for Non-comparable G&A General and administrative expenses increased $13.6M in Q1 2018 as compared to Q1 2017. The increase was driven by $4.8M in non- comparable items that do not otherwise relate to Inovalon's ongoing performance, $4.4M in acquired G&A associated with the CCS acquisition, and $4.3M in combined employee-related and professional fees associated with the Inovalon ONETM Platform development, launch, and associated data center expansions. Additionally, certain G&A expense synergies have been implemented and achieved in Q1 2018 reducing expenses by approximately $2.5M on average per quarter going forward. Normalized for certain non-comparable or one-time expenses, Inovalon's quarterly G&A expense is expected to range between $40M to $44M during the three remaining quarters of 2018 excluding G&A related to the acquisition of ABILITY, and $49M to $53M including ABILITY.
