While the Company has signed significant new and expanded business, the date of these signings was later than initially projected. This combination of factors in 2018 yields an updated full-year revenue guidance of $525M to $545M, or expected revenue expansion of 19% at the midpoint.

INOV Q3 2018 Earnings Supplement (11.7.18) v1.0.0 1. Information Made Newly Available By Going Publieled A Period of Competition & Downward Market Pricing Pro The first-time disclosure of the Company's strong profitability (approximately 35% Adjusted EBITDA margins) and customer list resulted in: a) Existing clients (which, at the time, were concentrated in the top ten customers representing 76% of revenues in 2014) exerted downward pricing pressure on the Company's solutions; and b) Armed with the newly available information (customer lists, product details, and clarity of business model success), Private Equity financed competitors' efforts to "copycat" the Inovalon model and attempt to poach Inovalon's newly revealed customers. 2. The Launch of Affordable Care Act Health Plans Brought With It Volatility As the ACA launched across the country in 2014, health plans and ACA- legislated COOPS turned to Inovalon to support multiple data-driven elements of their business models. After a period of initial growth, ACA plans and COOPS began facing political uncertainty resulting in a period of market instability (not unlike Medicare Advantage's initial three years); 3. Inovalon had Under-Invested in Sales & Marketing Prior to going public, Inovalon had grown for more than a decade with only approximately 2% of revenue spent on Sales & Marketing. This low amount (and the scale of Sales & Marketing operations within the Company represented by such an amount) was inadequate to counter the aforementioned headwinds experienced in the aftermath of going public. 30#31Evolution of Inovalon II || Having faced a number of headwinds after going public in 2015, Inovalon leveraged its strong technology foundation, cash flow, and balance sheet to position the Company for strong sustained growth as a leader in empowering data-driven healthcare. INOV Q3 2018 Earnings Supplement (11.7.18) v1.0.0 1. Accelerated Investment in Technology Innovation Increasing capital investments from the historical rate of 6% of revenue (in 2013, 2014, and 2015) to a high of 15% in 2017, Inovalon: a) Transitioned from an enterprise software platform offering to a cloud native platform offering known as the Inovalon ONE® Platform; b) Accelerated dataset expansion and platform connectivity growth; and c) Accelerated real-time compute, analytics, NLP, and ML initiatives. 2. Undertook Targeted M&A Executed on three material acquisitions achieving: a) De-concentration of client base; b) Diversification from Payers into Providers, Pharmacy, & Life Sciences; and c) Vertical integration from large Payers, Providers, Pharmacy, and Life Sciences organizations all the way down to the consumer's Point-of-Care. 3. Transitioned Contract Base to Cloud-Based, Subscription-Based Engagements With the average contract duration being approximately 3 years, Inovalon has now transitioned more than 80% of its business to a subscription-based model - suffering a short-term revenue impact in the process. 4. Focused on Highest Value Elements of Data-Driven Healthcare Transitioned away from labor-intensive elements of Inovalon's earlier business model to increasingly being pure SaaS-based. 5. Invested Heavily in Sales & Marketing Increased Sales & Marketing from 2% of revenue in 2015 to nearly 8%. 31#32Evolution of Inovalon III After three years of implementation, the Company's multifaceted strategy has positioned Inovalon for strong, sustained growth as a highly differentiated, pure- play leader in empowering data-driven healthcare. INOV Q3 2018 Earnings Supplement (11.7.18) v1.0.0 1. Capital Investment Amounts are Returning to His Levels After having increased capital investments from the historical rate of 6% of revenue (in 2013, 2014, and 2015) to a high of 15% in 2017, Inovalon has decreased CapEx to an expected run-rate of 8% to 9% of revenue. 2. Profitability Has Re-Expanded With market-leading capabilities being brought to the marketplace and clients experiencing strong, high ROI, value-added results, Inovalon is achieving: a) Improved pricing-power in the marketplace; b) Gross margin re-expansion to > 70%; and c) Adjusted EBITDA margin re-expansion to > 30% despite significant investments in technology, management, and Sales & Marketing. 3. Expanded Datasets, Connectivity, Analytical Prowess and Technology Sophistication With the heavy investments made on top of the Company's historical foundation, the result has been a deepening of the Company's moats. 4. Significant De-Concentrating & Diversification of Client Base The Company has gone from 100+ clients to 20,000+ in three years, expanding from a Payer-focus, to a portfolio of Providers, Pharmacy, and Life Sciences clients with the top 10 clients going from representing 76% of revenue in 2014 to an expected approximately 44% in 2018. 5. Inovalon Being Adopted as Market-Leading Capabilities Significant number of multi-year contracts being engaged with multiple industry leaders to support critical elements of their respective businesses. 32#33Contents This presentation serves as a supplement to the Inovalon announcement November 7, 2018 pertaining to third quarter (Q3) of 2018 results and guidance.
