BOWIE, Md. – August 1, 2018– Inovalon (Nasdaq: INOV), a leading technology company providing advanced, cloud-based platforms empowering data-driven healthcare, today announced financial results for the second quarter of 2018.

“Inovalon executed well across several important initiatives in the second quarter of 2018, delivering strong financial results and further expanding our platform capabilities, differentiation, and adoption in the marketplace,” said Keith Dunleavy, M.D., Inovalon’s chief executive officer and chairman of the board. “The progress achieved in the period was the result of a longstanding focus on innovation, great client partner relationships, a discipline towards cost efficiencies, and a tremendous effort from the entire Inovalon team as we execute on our vision to empower data-driven healthcare.”

Second Quarter 2018 Financial Results

• Revenue for the second quarter of 2018 was $152.8 million, a year-over-year increase of 38% compared with $110.6 million for the second quarter of 2017, and a sequential increase of 65% compared with $92.8 million for the first quarter of 2018.

• Cost of revenue for the second quarter of 2018 was $39.0 million, or 25.5% of revenue, compared with $37.2 million, or 33.6% of revenue for the second quarter of 2017, and $33.5 million, or 36.1% of revenue for the first quarter of 2018. This equates to gross margin for the second quarter of 2018 of 74.5%, a year-over-year increase of 810 basis points compared with 66.4% for the second quarter of 2017, and a sequential increase of 1,060 basis points compared with 63.9% for the first quarter of 2018.

• Net loss for the second quarter of 2018 was $10.5 million, resulting in net loss of $0.07 per share, compared with net income of $5.5 million and diluted net income of $0.04 per share, respectively, for the second quarter of 2017, and net loss of $16.8 million and net loss of $0.12 per share, respectively, for the first quarter of 2018. Net loss for the second quarter of 2018 includes a one-time restructuring expense of $9.5 million.

• Adjusted EBITDA for the second quarter of 2018 was $52.8 million, a year-over-year increase of 90% compared with $27.7 million for the second quarter of 2017, and a sequential increase of 571% compared with $7.9 million for the first quarter of 2018. Adjusted EBITDA margin for the second quarter of 2018 was 34.6%, a year-over-year increase of 950 basis points compared with 25.1% for the second quarter of 2017, and a sequential increase of 2,610 basis points compared with 8.5% for the first quarter of 2018.

• Non-GAAP net income for the second quarter of 2018 was $19.3 million, resulting in Non-GAAP net income per share of $0.13, increases of 64% and 63%, respectively, compared with $11.8 million and $0.08 per share, respectively, for the

second quarter of 2017, and Non-GAAP net loss of $5.0 million and Non-GAAP net loss of $0.04 per share, respectively, for the first quarter of 2018.

• Net cash provided by operating activities for the first six months of 2018 was $20.1 million, compared with $41.1 million for the first six months of 2017.

“During the second quarter, the Company executed well across a complex set of initiatives involving nearly every facet of the business,” said Jonathan Boldt, vice president of finance and interim chief financial officer of Inovalon. “The combination of an increasing number of growth engines within the Company and the successful realization of multiple margin improvement initiatives combined to produce strong financial results for the quarter. As we move forward through the balance of the year, we remain dedicated to disciplined execution of our strategic initiatives.”

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

• ABILITY Integration. Integration of ABILITY Network progressed well during the second quarter with strong combined team engagement. In addition to achieving cost synergies in-line with previously projected targets and timelines, significant benefits are also being realized through expanded management strength and the application of several strong best-practices resident within ABILITY. Multiple additional new synergy product offerings and capability enhancements are progressing well at various stages of the go-to-market process with in-year launches expected.

• Continued Innovation. During the second quarter, the Company continued to advance the capabilities and offerings empowered through the Inovalon ONE^® Platform. Direct EHR connectivity, even before the addition of connectivity gained through ABILITY, expanded to more than 185,000 unique physicians. This reflects a year-over-year increase of more than 70%, further increasing the market value and supporting adoption and growth of the Company’s recently released Clinical Data Extraction as a Service (CDEaaS™) solution. Additionally, the completion of a two-year development project produced the capability referred to as Elastic Container Technology, or ECT™ (as announced by the Company on July 26, 2018), enabling significant expansion in cloud-based computational speed, elasticity, resiliency, and scalability, while also reducing related technology operating costs materially.

• Inovalon ONE^® Platform Adoption. During the second quarter, the Company saw continued expansion of interest and adoption of cloud-based SaaS solutions enabled by the Inovalon ONE^® Platform. Both of the most recent announced platform offerings, specifically CDEaaS™ and ScriptMed™ Cloud, announced on April 10, 2018 and May 8, 2018 respectively, achieved multiyear contract wins during the quarter. Most notable was the five-year engagement to implement ScriptMed™ Cloud announced with AllianceRx Walgreens Prime (ARxWP) to support all ARxWP Specialty Pharmacy operations. Specialty Pharmacy is the fastest growing segment of the healthcare ecosystem, growing rapidly from approximately $178 billion in 2015 to a projected $282 billion by 2020 according to industry analysts. ScriptMed™ Cloud brings to this marketplace a cloud native, SaaS-based solution empowering a new generation of data-driven specialty pharmacy capabilities, delivering increased efficiency, lower operating costs, and improved patient outcomes and experience.

• Expanding Efficiencies and Profitability. During the second quarter, Inovalon executed a broad range of efficiency-enhancement and cost-reduction initiatives, both as part of its ongoing margin expansion goals, as well as related to the recent acquisition and ongoing integration of ABILITY. Key to these were a focus on increasing automation, further expansion of industry connectivity, and cost reduction actions to consolidate facilities and eliminate redundant functions. Reflecting the cost reduction actions, a one-time restructuring expense of $9.5 million was incurred during the period. In addition to the aforementioned cost efficiency initiatives, the ongoing expansion of the Company’s technology-enabled capabilities resulted in a continued positive product mix shift towards high-value SaaS offerings. The combined benefits of these factors can be seen in the Company’s strong margin performance in the second quarter of 2018, as well as in the strong financial performance expected going forward in 2018.

Other Financial Data and Key Metrics

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

• Growth of Datasets: At June 30, 2018, the MORE² Registry^® dataset contained more than 252 million unique patient counts and 39 billion medical event counts, increases of 10% and 31%, respectively, compared with June 30, 2017. Data resulting from the integration with ABILITY is not yet reflected within the MORE² Registry^® dataset and is therefore not reflected within the aforementioned data metrics as of this date.

• Investment in Innovation: For the quarter ended June 30, 2018, Inovalon’s ongoing investment supporting innovations in advanced, cloud-based platforms empowering data-driven healthcare was $19.6 million, or 12% of revenue, a decrease of $2.3 million, or 10%, 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 46.2 billion as of June 30, 2018, an increase of 48% as compared with June 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.

Key Metrics (unaudited)

The Company believes the key metrics illustrated in the tables below are indicative of its overall level of analytical activity and its underlying growth in the business. Data resulting from the integration with ABILITY Network is not yet reflected within the MORE² Registry^® dataset and is therefore not reflected within the related data metrics below as of this date.

	June 30,
(In thousands)	2018	2017
MORE2 Registry® dataset metrics
Unique patient count(1)(4)	252,603	230,000
Medical event count(2)(4)	39,333,463	30,000,000
Trailing 12 month Patient Analytics Months (PAM)(3)	46,152,155	31,226,926

_______________________________________________________

(1) Unique patient count is defined as each unique, longitudinally matched, de-identified natural person represented in the MORE² Registry^® as of the end of the period presented.

(2) Medical event count is defined as the total number of discrete medical events as of the end of the period presented (for example, a discrete medical event typically results from the presentation of a patient to a physician for the diagnosis of diabetes and congestive heart failure in a single visit, the presentation of a patient to an emergency department for chest pain, etc.).

(3) Patient Analytics Months, or PAM, is defined as the sum of the analytical processes performed on each respective patient within patient populations covered by clients under contract. As used in the metric, an “analytical process” is a distinct set of data calculations undertaken by the Company which is initiated and completed within the Company’s platform solutions to examine a specific question such as whether a patient is believed to have a condition such as diabetes, or worsening of the disease, during a specific time period.

(4) At the end of the year-ago quarter, specifically as of June 30, 2017, the Company was processing large unique patient count and medical event count dataset transmissions. For this reason, June 30, 2017 unique patient count and medical event count amounts vary from historical calculation methodologies, and represent estimates pending final MORE² Registry^® dataset incorporation and processing.

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, realized losses on short-term investments, loss or gain on disposal of equipment, 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, 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.
