Adjusting for Non-Comparable G&A General and administrative expenses increased $10.9M in Q3 2018 as compared to Q3 2017. The increase was driven by $5.3M in non- comparable items that do not otherwise relate to Inovalon's ongoing performance and $7.5M in acquired G&A associated with ABILITY Network, which was partially offset by a reduction of $1.9M in combined employee-related and professional fees. Normalized G&A for Q3 2018 was $41.9M, reflecting a YOY increase of only 15.4% in the setting of a YOY revenue increase of 26.1%. $36.3 Q3 2017 Actual ($1.9) Employee-Related Expenses & Professional Fees $7.5 INOV Q3 2018 Earnings Supplement (11.7.18) v1.0.0 Acquired G&A $5.3 Million in Non-Comparable or One-Time Expenses $4.6 Change in Acquisition-Related Contingent Consideration *Normalized G&A excludes the impact from fair value contingent consideration accretion measurement.
