BOWIE, Md. – November 7, 2018– Inovalon (Nasdaq: INOV), a leading technology company providing advanced, cloud-based platforms empowering data-driven healthcare, today announced financial results for the third quarter of 2018, updated guidance for the remainder of 2018, as well as guidance for the full year 2019.

“We have seen an increasingly strong inflection in our business on many fronts over the recent months with significant increases in client retention rates, renewal performance, and new sales, all while concurrently continuing to expand value to clients and margin performance for the Company,” said Keith Dunleavy, M.D., Inovalon’s chief executive officer and chairman of the board. “While the timing of some new and expanded business engagements has been later than we previously estimated, and the conversion of substantially all remaining legacy contracts to subscription-based contracts and discontinued pursuit of new legacy contracts impacted revenue for the few months remaining of the year, steep increases in multiple relevant metrics across the board are driving a strong 2019 outlook of 19% to 23% revenue growth, including organic growth of 12% to 14%, and strong Adjusted EBITDA, all with nearly 95% coverage visibility even at this early date.”

Third Quarter 2018 Financial Results

• Revenue for the third quarter of 2018 was $145.8 million, a year-over-year increase of 26% compared with $115.9 million for the third quarter of 2017.

• Cost of revenue for the third quarter of 2018 was $36.4 million, or 25.0% of revenue, compared with $38.4 million, or 33.2% of revenue for the third quarter of 2017. This equates to gross margin for the third quarter of 2018 of 75.0%, a year-over-year increase of 820 basis points compared with 66.8% for the third quarter of 2017. Removing the impact of ABILITY, gross margin for the third quarter of 2018 was 70.9%, a sequential increase of 70 basis points from the second quarter of 2018 and a year-over-year increase of 410 basis points compared to the third quarter of 2017.

• Net loss for the third quarter of 2018 was $0.8 million, resulting in net loss of $0.01 per share, compared with net income of $8.2 million and diluted net income of $0.06 per share, respectively, for the third quarter of 2017.

• Adjusted EBITDA for the third quarter of 2018 was $52.4 million, a year-over-year increase of 70% compared with $30.8 million for the third quarter of 2017. Adjusted EBITDA margin for the third quarter of 2018 was 36.0%, a year-over-year increase of 940 basis points compared with 26.6% for the third quarter of 2017.

• Non-GAAP net income for the third quarter of 2018 was $16.3 million, resulting in Non-GAAP net income per share of $0.11, increases of 30% and 22%, respectively, compared with $12.6 million and $0.09 per share, respectively, for the third quarter of 2017.

• Net cash provided by operating activities for the third quarter of 2018 was $42.9 million. For the first nine months of 2018, net cash provided by operating activities was $63.0 million compared with $80.9 million for the first nine months of 2017.

“Inovalon’s increasing mix of high-value SaaS-based solutions, as well as our ongoing investments in automation and efficiencies, allowed the Company to continue its strong margin expansion and solid cash flow in the third quarter,” said Jonathan Boldt, vice president of finance and interim chief financial officer of Inovalon. “With our successful transition to a subscription-based model now substantially complete, year-to-date strength in new business signings, and improved revenue retention outlook, the Company has gained significant visibility into our 2019 revenue outlook, showing strong revenue growth and continued profitability expansion.”

Adjusted EBITDA, Adjusted EBITDA margin, and Non-GAAP net income are Non-GAAP measures. Net income is the GAAP financial measure most directly comparable to Adjusted EBITDA and Non-GAAP net income. Reconciliations of net income to Adjusted EBITDA and Non-GAAP net income, identifying the differences between net income and each of these Non-GAAP financial measures, are included in this press release after the consolidated financial statements.

Key Highlights

• Transition to Subscription-Based Model. In the third quarter, 83% of Inovalon’s revenue was generated from subscription-based platform offerings, up from 66% in the third quarter of 2017 and up from 78% in the second quarter of 2018. Excluding ABILITY’s contribution, subscription-based revenue increased organically 8.6% year-over-year and 2.6% sequentially, driven by new and expanded client engagements utilizing subscription-based platform offerings of the Inovalon ONE^® Platform. As part of the transition, the Company converted substantially all remaining legacy contracts to subscription-based contracts and discontinued the pursuit of additional new legacy contracts, the combination of which contribute to a short-term revenue impact of approximately $25 million versus previous expectations for 2018. By year-end, legacy revenue is expected to be down to approximately 7% of consolidated revenue, making the conversion of legacy to subscription-based contracts a substantially completed process.

• Expanding Profitability. Third quarter 2018 gross margin of 75.0% increased 820 basis points year-over-year, driven by the Company’s solution mix continuing to shift to high-value, data-driven SaaS offerings, as well as ongoing leverage from automation and connectivity. Third quarter 2018 Adjusted EBITDA margin of 36.0% increased 940 basis points year-over-year, driven by higher gross margin, as well as G&A leverage from ongoing efficiency-enhancement and cost-reduction initiatives begun earlier this year, including facility consolidation, internal process improvement, and the continued integration of ABILITY.

• Integration of ABILITY Progressing as Expected. The Company’s integration of ABILITY continued to progress well during the third quarter, both in terms of strong cultural alignment between the organizations, as well as the achievement of cost and revenue synergies. Nearly all of the forecasted $8 million in cost synergies expected for 2018 have been achieved as of the end of the third quarter and the Company is on track to achieve the full $11 million run rate cost synergies expected for 2019. In addition, the Company has started to realize synergy revenue from the combination, and sees a healthy synergy product pipeline heading into 2019.

• Strong Inovalon ONE^® Platform Adoption and Client Retention. In the third quarter, Inovalon saw accelerating interest and adoption of cloud-based SaaS solutions enabled by the Inovalon ONE^® Platform, as well as a notably positive progression in client retention and renewal performance. Year-to-date through September 30^th, excluding the contribution from ABILITY and Services, Annualized Contract Value (ACV) from new contract wins and existing contract expansions was $96.2 million, up 91% from the comparable period in 2017. Demonstrating the accelerating Inovalon ONE^® Platform adoption, ACV signed during the third quarter alone, excluding ABILITY and Services, was $52.1 million, a 101% year-over-year increase. ACV signed excluding just ABILITY, for the third quarter of 2018 and YTD through September 30^th,

was $62.3 million and $139.9 million, respectively, increases of 60% and 50%, respectively, from the comparable year-ago periods. In addition, YTD through September 30^th, Inovalon signed engagements with 82 new logos, a year-over-year increase of 28% versus the same period in 2017, contributing three points of the projected growth in 2019. Furthermore, the Company’s increasingly differentiated solutions drove sharp increases in client renewals, helping to drive projected 2019 Annual Revenue Retention to 103%, contributing an additional three points of organic growth versus a headwind of five to six points in the last two years.

• Enhanced Revenue Visibility. With a differentiated and expanding portfolio of cloud-based SaaS solutions enabled by the Inovalon ONE^® Platform, the successful transition to a subscription-based revenue model, and strong client revenue retention and new business signings, Inovalon has increasing revenue visibility and predictability going forward. In this setting, the Company is providing 2019 financial guidance earlier, and with significantly higher initial coverage, than in past years. Specifically, as of the date of this release, Inovalon has coverage of approximately 94.5% of the Company’s 2019 revenue guidance midpoint, providing visibility well above levels from the prior two years of approximately 85%. Inovalon’s initial 2019 guidance implies revenue growth of 19% to 23% (inclusive of 12% to 14% of organic growth), with only approximately 5 points of growth still to be solutioned against the backdrop of a strong demand environment and healthy pipeline of opportunities, as well as the earlier date of guidance provision than previous years.

Other Financial Data and Key Metrics

The following constitute other financial data and key metrics which are presented quarterly.

• Growth of Datasets: At September 30, 2018, the MORE² Registry^® dataset contained more than 261 million unique patient counts and 40 billion medical event counts, increases of 13% and 17%, respectively, compared with September 30, 2017. Data resulting from the integration with ABILITY is not yet fully reflected within the MORE² Registry^® dataset and is therefore not fully reflected within the aforementioned data metrics as of this date.

• Investment in Innovation: For the quarter ended September 30, 2018, Inovalon’s ongoing investment supporting innovations in advanced, cloud-based platforms empowering data-driven healthcare was $17.0 million, or 12% of revenue, a decrease of $2.8 million, or 14%, compared to the prior year period.

• Analytical Process Count Growth: Inovalon’s trailing 12-month Patient Analytics Months (PAM) count, which the Company believes is indicative of the Company’s overall level of analytical activity, grew to 47.1 billion as of September 30, 2018, an increase of 29% as compared with September 30, 2017.

Please see the Company’s filings with the Securities and Exchange Commission (“SEC”) for further detail regarding the preceding other financial data and key metrics.

Shares Outstanding

As of October 26, 2018, the Company had 71.8 million shares of Class A common stock outstanding and 80.6 million shares of Class B common stock outstanding.

2018 Financial Guidance

The Company is revising its 2018 financial guidance to reflect (1) the later than expected timing for certain new contracts, which are now signed and at various stages of implementation, (2) the conversion of substantially all remaining legacy contracts to subscription-based contracts, and (3) the discontinued pursuit of new legacy business (and therefore the removal of such legacy contribution expectation from previous guidance). Revised 2018 financial guidance is as follows.

Financial Metric	Updated Guidance Range Provided November 7, 2018	Previous Guidance Range Provided August 1, 2018
Revenue	$525 million to $545 million	$568 million to $593 million
Net (loss) income(1)	($38 million) to ($28 million)	($24 million) to ($18 million)
Non-GAAP net income	$39 million to $50 million	$50 million to $58 million
Adjusted EBITDA	$150 million to $166 million	$166 million to $176 million
Net cash provided by operating activities	$90 million to $100 million	$90 million to $100 million
Non-GAAP net cash provided by operating activities	$104 million to $115 million	$104 million to $115 million
Capital expenditure(2)	$55 million to $60 million	$55 million to $60 million
Diluted net (loss) income per share	($0.26) to ($0.19)	($0.16) to ($0.12)
Non-GAAP diluted net income per share	$0.27 to $0.34	$0.34 to $0.40

_______________________________________________________

(1) GAAP net (loss)/income includes estimated: one-time restructuring costs of $9.5 million, acquisition-related contingent consideration expense of $14.0 million, transaction costs of $7.0 million, non-recurring integration costs of $7.5 million, and intangible asset amortization of $44.0 million.

(2) Capital expenditure is defined as the sum of purchases of property and equipment and investment in capitalized software.

Additional assumptions made within the Company's 2018 guidance are as follows:

• While changes in the stock price could change the fully diluted share count, under the treasury stock method, 2018 guidance assumes 146 million weighted average diluted shares.

• 2018 guidance assumes an effective tax rate of approximately 30% for the full year.

2019 Financial Guidance

In the setting of a now predominantly subscription-based contract portfolio, significantly increased client retention performance, existing client membership expansion projections, new client sales, and a resulting strong Annual Recurring Revenue base, Inovalon has significant visibility into 2019, providing for annual guidance for the period as provided below.

Financial Metric	2019 Guidance Range
Revenue	$637 million to $657 million
Net (loss) income	$1 million to $5 million
Non-GAAP net income	$61 million to $69 million
Adjusted EBITDA	$200 million to $210 million
Net cash provided by operating activities	$130 million to $145 million
Capital expenditure	$52 million to $58 million
Diluted net (loss) income per share	$0.01 to $0.03
Non-GAAP diluted net income per share	$0.41 to $0.47

Additional assumptions made within the Company's 2019 guidance are as follows:

• While changes in the stock price could change the fully diluted share count, under the treasury stock method, 2019 guidance assumes 149 million weighted average diluted shares.

• 2019 guidance assumes an effective tax rate of approximately 30% for the full year.

Reconciliations of net income, the GAAP financial measure most directly comparable to Adjusted EBITDA and Non-GAAP net income, and of net cash provided by operating activities, the GAAP financial measure most directly comparable to Non-GAAP net cash provided by operating activities, identifying the differences between each of these Non-GAAP financial measures and the most directly comparable GAAP financial measure, are included in this press release after the consolidated financial statements.

¹ Annualized Contract Value (ACV) is defined as the total revenue expected from a contract divided by the duration of that contract.

² Annual Revenue Retention is defined as the percentage of revenue from engagements with existing clients in the prior year present in the current year. For example, Annual Revenue Retention would be less than 100% if there was a net loss of revenue from existing clients who either downsized or exited existing engagements, and would be more than 100% if on a net basis existing clients expanded existing engagements.

³ Annual Recurring Revenue is defined as subscription-based revenue from existing clients plus outstanding intra-year renewals valued at an amount agreed upon in principal.

⁴ Coverage is defined as the sum of Annual Recurring Revenue, Legacy revenue under contract, and expected Services revenue, divided by the specified year's revenue guidance.

Forward-Looking Guidance Non-GAAP net cash provided by operating activities (unaudited)

The Company defines Non-GAAP net cash provided by operating activities as net cash provided by operating activities calculated in accordance with GAAP, adjusted to exclude certain acquisition costs, specifically transaction costs and integration costs. The Company uses Non-GAAP net cash provided by operating activities as a liquidity measure to evaluate its ability to generate cash to support its ongoing business operations, to service and repay debt, and to invest in its businesses. A reconciliation of forward-looking preliminary net cash provided by operating activities to forward-looking preliminary Non-GAAP net cash provided by operating activities follows:

Non-GAAP Financial Measures

Inovalon provides the measures Adjusted EBITDA, Adjusted EBITDA margin, and Non-GAAP net income as additional information for evaluating the Company’s operating results and Non-GAAP net cash provided by operating activities as a liquidity measure to evaluate the Company's ability to generate cash to support its ongoing business, to service and repay debt, and to invest in its business. These measures are not prepared in accordance with, or as an alternative for, GAAP accounting and may be different from non-GAAP measures used by other companies.

Investors frequently have requested information from management regarding depreciation, amortization and other non-cash charges, such as stock-based compensation, as well as the impact of non-comparable items and management believes, based on discussions with investors, that these non-GAAP measures enhance investors’ ability to assess Inovalon’s historical and projected future financial performance. While management believes these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of non-GAAP financial measures. For example, one limitation of Adjusted EBITDA is that it excludes depreciation and amortization, which represents the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in our business. Inovalon compensates for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by reconciling the non-GAAP financial measures to their most comparable GAAP financial measures. Investors are encouraged to review the reconciliations of these non-GAAP financial measures to the comparable GAAP measures that are provided above.

These non-GAAP measures include financial information that is prepared in accordance with GAAP and presented in our consolidated financial statements and are used to evaluate our business, measure our performance, develop financial forecasts and make strategic decisions and are an important factor in determining variable compensation.

Adjusted EBITDA and Adjusted EBITDA Margin

The Company defines Adjusted EBITDA as net income calculated in accordance with GAAP, adjusted for the impact of depreciation and amortization, other expense, net, interest income, interest expense, provision for income taxes, stock-based compensation, acquisition costs (including transaction costs, integration costs, costs related to contingent consideration accretion and compensatory contingent consideration), restructuring expense, tax on equity exercises, and other non-comparable items. A reconciliation of net income, which is the most directly comparable GAAP financial measure, to Adjusted EBITDA is provided above.

Adjusted EBITDA margin is the Company’s calculation of Adjusted EBITDA, divided by revenue calculated in accordance with GAAP.

The Company uses Adjusted EBITDA and Adjusted EBITDA margin as supplemental measures of performance to gain insight into operating effectiveness. The Company uses Adjusted EBITDA and Adjusted EBITDA margin as key metrics to assess its ability to increase revenues while controlling expense growth and the scalability of the Company’s business model. The Company believes that the exclusion of the expenses eliminated in calculating Adjusted EBITDA and Adjusted EBITDA margin provides management and investors a useful measure for period-to-period comparisons of the Company’s core business and operating results by excluding items that are not comparable across reporting periods or that do not otherwise relate to the Company’s ongoing operating results. Accordingly, the Company believes that Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors and others in understanding and evaluating the Company’s operating results. However, use of Adjusted EBITDA and Adjusted EBITDA margin as analytical tools has limitations, and investors and others should not consider them in isolation or as substitutes for analysis of our financial results as reported under GAAP. In addition, other companies, including companies in Inovalon’s industry, might calculate Adjusted EBITDA and Adjusted EBITDA margin or similarly titled measures differently, which may reduce their usefulness as comparative measures.

Non-GAAP net income and Non-GAAP net income per share

The Company defines Non-GAAP net income as net income calculated in accordance with GAAP, adjusted to exclude tax-affected stock-based compensation expense, acquisition costs (including transaction costs, integration costs, costs related to contingent consideration accretion and compensatory contingent consideration), restructuring expense, amortization of acquired intangible assets, amortization of debt issuance costs and debt discount, tax on equity exercises, and other non-comparable items.

The Company defines Non-GAAP basic net income per share as Non-GAAP net income divided by basic weighted average shares outstanding. The Company defines Non-GAAP diluted net income per share as Non-GAAP net income divided by diluted weighted average shares outstanding.

The Company uses Non-GAAP net income as a supplemental measure of performance to gain insight into financial effectiveness. The Company uses Non-GAAP net income as a key metric to assess its ability to increase revenues while controlling expense growth and the scalability of its business model. The Company believes that the exclusion of the expenses eliminated in calculating Non-GAAP net income provides management and investors a useful measure for period to period comparisons of the Company’s core business and financial results by excluding items that are not comparable across reporting periods or that do not otherwise relate to its ongoing financial results. Accordingly, the Company believes that Non-GAAP net income provides useful information to investors and others in understanding and evaluating the Company’s performance. However, use of Non-GAAP net income as an analytical tool has limitations, and investors and others should not consider this measure in isolation or as a substitute for analysis of the Company’s financial results as reported under GAAP. In addition, other companies, including companies in Inovalon’s industry, might calculate Non-GAAP net income or similarly titled measures differently, which may reduce their usefulness as comparative measures.

Non-GAAP net cash provided by operating activities

The Company defines Non-GAAP net cash provided by operating activities as net cash provided by operating activities calculated in accordance with GAAP, adjusted to exclude certain acquisition costs, specifically transaction costs and integration costs. The Company uses Non-GAAP net cash provided by operating activities as a liquidity measure to evaluate its ability to generate cash to support its ongoing business operations, to service and repay debt, and to invest in its businesses. The Company believes that the exclusion of certain acquisition costs in calculating Non-GAAP net cash provided by operating activities provides management and investors a useful measure for the expected cash flows generated from the Company’s core business by excluding items that do not otherwise relate to its ongoing liquidity. However, use of Non-GAAP net cash provided by operating activities has limitations, and investors and others should not consider this measure in isolation or as a substitute for analysis of the Company’s liquidity as reported under GAAP. In addition, other companies, including companies in Inovalon’s industry, might calculate Non-GAAP net cash provided by operating activities or similarly titled measures differently, which may reduce their usefulness as comparative measures.
