Use of Non-GAAP Financial Measures Glu uses in this presentation certain non-GAAP measures of financial performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation from, as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP, and may be different from non- GAAP financial measures used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Glu's results of operations as determined in accordance with GAAP. The non-GAAP financial measures used by Glu include non-GAAP revenues, non-GAAP smartphone revenues, non-GAAP cost of revenues, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating margin, non-GAAP net income/(loss), non-GAAP net income/(loss) per share and Adjusted EBITDA. These non-GAAP financial measures exclude the following items from Glu's unaudited consolidated statements of operations: • Change in deferred revenues and deferred cost of revenues; • Amortization of intangible assets; • Stock-based compensation expense; • Restructuring charges; • Change in fair value of Blammo earnout; • Transitional costs; • Impairment of goodwill; • Release of tax liabilities; and • Foreign currency exchange gains and losses primarily related to the revaluation of assets and liabilities. In addition, Glu has included in this presentation “Adjusted EBITDA” figures which are used to evaluate Glu’s operating performance and is defined as non-GAAP operating income/(loss) excluding depreciation. Glu believes that these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provide meaningful supplemental information regarding Glu's performance by excluding certain items that may not be indicative of Glu's core business, operating results or future outlook. Glu's management uses, and believes that investors benefit from referring to, these non-GAAP financial measures in assessing Glu's operating results, as well as when planning, forecasting and analyzing future periods. These non-GAAP financial measures also facilitate comparisons of Glu's performance to prior periods. For a reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures, please refer to the tables attached to Glu’s earnings press release for the quarter ended June 30, 2013, which is available on our website at http://www.glu.com/investors. © Glu Mobile Inc. – Proprietary Page 3 |
