Redwood City, CA – Model N, Inc., (NYSE: MODN), the leader in Revenue Management Cloud solutions to the life science and technology industries, today announced financial results for the third quarter of fiscal year 2015, which ended June 30, 2015.

“Model N executed extremely well in the third quarter of fiscal year 2015 putting ourselves in position to leverage an environment of improved demand. We believe the market will soon reach two important tipping points.

Our third quarter results are strong testaments to the Model N vision of revenue management, the robust market for revenue management, and our strategy to concurrently drive growth and to transform our business to SaaS and recurring revenues.”

The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” and similar expressions are intended to identify forward-looking statements. These forward-looking statements are subject to risks, uncertainties, and assumptions. If the risks materialize or assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. Risks include, but are not limited to: (i) delays in closing customer contracts; (ii) our ability to improve and sustain our sales execution; (iii) the timing of new orders and the associated revenue recognition; (iv) adverse changes in general economic or market conditions; (v) delays or reductions in information technology spending and resulting variability in customer orders from quarter to quarter; (vi) competitive factors, including but not limited to pricing pressures, industry consolidation, entry of new competitors and new applications and marketing initiatives by our competitors; (vii) our ability to manage our growth effectively; (viii) acceptance of our applications and services by customers; (ix) success of new products; (x) the risk that the strategic initiatives that we may pursue will not result in significant future revenues; and (xi) our ability to retain customers.

Non-GAAP Financial Measures

We have provided in this release financial information that has not been prepared in accordance with accounting standards generally accepted in the United States of America (“GAAP”). We use these non-GAAP financial measures internally in analyzing our financial results and believe they are useful to investors, as a supplement to GAAP measures, in evaluating our ongoing operational performance. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial results with other companies in our industry, many of which present similar non-GAAP financial measures to investors.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures below. A reconciliation of our non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included below in this press release.

Our reported results include certain non-GAAP financial measures, including non-GAAP gross profit, non-GAAP loss from operations, non-GAAP net loss, non-GAAP net (loss) income per share, and adjusted EBITDA. Non-GAAP gross profit excludes stock-based compensation expense, LeapFrogRX compensation charges and amortization of intangible assets. Non-GAAP loss from operations and non-GAAP net loss exclude stock-based compensation expense, LeapFrogRX compensation charges, amortization of intangible assets, certain legal expenses and restructuring charges as they are often excluded by other companies to help investors understand the operational performance of their business and, in the case of stock-based compensation, can be difficult to predict. In addition, stock-based compensation expense varies from period to period and company to company due to such things as differing valuation methodologies and changes in stock price. Adjusted EBITDA is defined as net loss, adjusted for LeapFrogRX compensation charges, depreciation and amortization, stock-based compensation expense, certain legal expenses, restructuring charges, interest income and other expenses, net, and provision for income taxes. Reconciliation tables are provided in this press release.

Use of Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements presented on a GAAP basis, Model N uses non-GAAP measures of adjusted EBITDA, gross profit, loss from operations, net loss, weighted average shares outstanding and net loss per share, which are adjusted to exclude LeapFrogRx compensation charges, stock-based compensation expense, restructuring charge and amortization of intangible assets and includes dilutive shares where applicable. We believe these adjustments are appropriate to enhance an overall understanding of our past financial performance and also our prospects for the future. These adjustments to our current period GAAP results are made with the intent of providing both management and investors a more complete understanding of Model N’s underlying operating results and trends and our marketplace performance. The non-GAAP results are an indication of our baseline performance that are considered by management for the purpose of making operational decisions. In addition, these non-GAAP results are the primary indicators management uses as a basis for our planning and forecasting of future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for operating loss, net loss or basic and diluted net loss per share prepared in accordance with generally accepted accounting principles in the United States. Non-GAAP financial measures are not based on a comprehensive set of accounting rules or principles and are subject to limitations.

While a large component of our expense in certain periods, we believe investors may want to exclude the effects of these items in order to compare our financial performance with that of other companies and between time periods:
