SAN FRANCISCO, Calif. — April 29, 2015 — Glu Mobile Inc. (NASDAQ:GLUU), a leading global developer and publisher of free-to-play games for smartphone and tablet devices, today announced financial results for its first quarter ended March 31, 2015.

“Glu delivered a strong start to 2015 evidenced by our ability to exceed expectations across all key metrics, particularly non-GAAP revenue which increased 33%,” stated Niccolo de Masi, Chairman and Chief Executive Officer of Glu.  “The outperformance during the first quarter was driven by the ongoing traction of Kim Kardashian: Hollywood, Racing Rivals, Deer Hunter 2014, and Contract Killer: Sniper.”

“We are excited to have struck an exclusive partnership with Grammy Award winner Britney Spears for up to eight years,” de Masi announced.  “Britney is a unique talent having sold over 100 million albums worldwide, been recognized with numerous industry accolades including, six MTV Video Music Awards, seven MTV Europe Music Awards, an American Music Award, nine Billboard Music Awards, five Teen Choice Awards, and a star on the Hollywood Walk of Fame.  Our Britney game will launch in H1 2016.”

Mr. de Masi continued, “I am delighted to announce today a strategic relationship with Tencent — arguably Asia’s largest internet company and the world’s largest gaming company.  We look forward to working with Tencent to drive operating synergies in China and the West for Glu.  Their investment in Glu at a premium to the current prevailing share price I view as recognition of our operating momentum and unique portfolio approach.”

Mr. de Masi concluded, “Our confidence in the increased 2015 guidance is driven by the strong lineup of titles including Terminator, Cooking Dash, Deer Hunter 2016, James Bond: 007 and Katy Perry.  Glu benefits from the combination of our diversified portfolio along with improving annuity characteristics in our franchises.  We are well positioned to maintain and grow momentum in H2 2015 and beyond.”

Therefore, Glu encourages investors, the media, players and others interested in Glu to review the information posted on the company forum (http://ggnbb.glu.com/forum.php) and the company Facebook site (https://www.facebook.com/glumobile), the company twitter account (https://twitter.com/glumobile) and Mr. de Masi’s twitter account (https://twitter.com/niccolodemasi). Investors, the media, players or other interested parties can subscribe to the company blog and twitter feed and Mr. de Masi’s twitter feed at the addresses listed above. Any updates to the list of social media channels Glu will use to announce material information will be posted on the Investor Relations page of the company’s website at www.glu.com/investors.

Use of Non-GAAP Financial Measures

To supplement Glu’s unaudited condensed consolidated financial data presented in accordance with GAAP, Glu uses 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 historical and estimated non-GAAP revenues, non-GAAP smartphone revenues, non-GAAP cost of revenues, non-GAAP operating expenses, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income/(loss), non-GAAP net income/(loss) and non-GAAP basic and diluted net income/(loss) per share. 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;

·                  Non-cash warrant expense;

·                  Stock-based compensation expense;

·                  Restructuring charges;

·                  Change in fair value of Blammo earnout;

·                  Transitional costs;

·                  Release of tax liabilities and valuation allowance; and

·                  Foreign currency exchange gains and losses primarily related to the revaluation of assets and liabilities.

In addition, Glu has included in this release “Adjusted EBITDA” figures which are used to evaluate Glu’s operating performance.  Adjusted EBITDA is defined as non-GAAP operating income/(loss) excluding depreciation.  Adjusted EBITDA margin is defined as Adjusted EBITDA divided by non-GAAP revenue.

Glu may consider whether significant non-recurring items that arise in the future should also be excluded in calculating the non-GAAP financial measures it uses.

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.

In addition to the reasons stated above, which are generally applicable to each of the items Glu excludes from its non-GAAP financial measures, Glu believes it is appropriate to exclude certain items for the following reasons:

Change in Deferred Revenues and Deferred Cost of Revenues. At the date we sell certain premium games and micro-transactions, Glu has an obligation to provide additional services and incremental unspecified digital content in the future without an additional fee. In these cases, we recognize the revenues and any associated cost of revenues, including platform commissions and royalties, on a straight-line basis over the estimated life of the paying user. Internally, Glu’s management excludes the impact of the changes in deferred revenue and deferred cost of revenues related to its premium and free-to-play games in its non-GAAP financial measures when evaluating the company’s operating performance, when planning, forecasting and analyzing future periods, and when assessing the performance of its management team. Glu believes that excluding the impact of the changes in deferred revenues and deferred cost of revenues from its operating results is important to facilitate comparisons to prior periods and to understand Glu’s operations.

Amortization of Intangible Assets. When analyzing the operating performance of an acquired entity, Glu’s management focuses on the total return provided by the investment (i.e., operating profit generated from the acquired entity as compared to the purchase price paid) without taking into consideration any allocations made for accounting purposes. Because the purchase price for an acquisition necessarily reflects the accounting value assigned to intangible assets (including acquired in-process technology and goodwill), when analyzing the operating performance of an acquisition in subsequent periods, Glu’s management excludes the GAAP impact of acquired intangible assets to its financial results. Glu believes that such an approach is useful in understanding the long-term return provided by an acquisition and that investors benefit from a supplemental non-GAAP financial measure that excludes the accounting expense associated with acquired intangible assets.

Non-cash Warrant Expense. In the third and fourth quarters of 2014 and the first quarter of 2015, Glu recorded a non-cash charge related to the vesting of warrants to purchase shares of common stock issued to brand holders as part of third party licensing, development and publishing arrangements. These charges were computed using the Black-Scholes valuation model and were recorded in cost of revenues. When evaluating the performance of its consolidated results, Glu does not consider non-cash warrant expense as it places a greater emphasis on overall stockholder dilution rather than the accounting charges associated with the vesting of any warrants. As the non-cash warrant expense impacts comparability from period to period Glu believes that investors benefit from a supplemental non-GAAP financial measure that excludes these charges.

Stock-Based Compensation Expense. The Company applies the fair value provisions of ASC 718, Compensation-Stock Compensation (“ASC 718”). ASC 718 requires the recognition of compensation expense, using a fair-value based method, for costs related to all share-based payments. Included in the stock compensation expense was the contingent consideration that was subsequently issued to the Blammo employees who were former shareholders of Blammo, which was recorded as research and development expense over the term of the earn-out periods, since these employees were primarily employed in product development. Glu re-measured the fair value of the contingent consideration each reporting period and only recorded a compensation expense for the portion of the earn-out target which was achieved. When evaluating the performance of its consolidated results, Glu does not consider stock-based compensation charges. Likewise, Glu’s management team excludes stock-based compensation expense from its short and long-term operating plans. In contrast, Glu’s management team is held accountable for cash-based compensation and such amounts are included in its operating plans. Further, when considering the impact of equity award grants, Glu places a greater emphasis on overall stockholder dilution rather than the accounting charges associated with such grants. Glu believes it is useful to provide a non-GAAP financial measure that excludes stock-based compensation in order to better understand the long-term performance of its business.

Restructuring Charges. Glu undertook restructuring activities in the second, third and fourth quarters of 2014 and recorded cash restructuring charges due to the termination of certain employees in its China, Europe and U.S. offices. Glu recorded the severance costs as an operating expense when it communicated the benefit arrangement to the employee and no significant future services, other than a minimum retention period, were required of the employee to earn the termination benefits. Glu believes that these restructuring charges do not reflect its ongoing operations and that investors benefit from a supplemental non-GAAP financial measure that excludes these charges.

Change in Fair Value of Blammo Earnout. As part of the acquisition of Blammo, Glu committed to issue additional consideration in the form of Glu’s common stock to the former, non-employee Blammo shareholders if certain revenue targets were achieved. Glu recorded the estimated contingent consideration liability at acquisition and adjusted the fair value of the liability each reporting period. When analyzing the operating performance of an acquired entity, Glu’s management focuses on the total return provided by the investment (i.e., operating profit generated from the acquired entity as compared to the purchase price paid including the final

amounts paid for contingent consideration) without taking into consideration any expenses recognized post-acquisition related to the change in fair value of the contingent consideration. Because the final purchase price paid for an acquisition necessarily reflects the accounting value assigned to both the consideration, including the contingent consideration, paid and to the intangible assets (including goodwill) acquired, when analyzing the operating performance of an acquisition in subsequent periods, the Company’s management excludes the GAAP impact of any adjustments to the fair value of these acquisition-related balances to its financial results. Glu believes that the fair value adjustments affect comparability from period to period and that investors benefit from a supplemental non-GAAP financial measure that excludes these charges.

Transitional Costs. GAAP requires expenses to be recognized for various types of events associated with a business acquisition such as legal, accounting and other deal related expenses. Glu has incurred various costs related to the acquisition and integration of PlayFirst and Cie Games into Glu’s operations. Glu recorded these non-recurring acquisition and transitional costs as operating expenses when they were incurred. Glu believes that these acquisition and transitional costs affect comparability from period to period and that investors benefit from a supplemental non-GAAP financial measure that excludes these expenses.

Release of tax liabilities and valuation allowance. In the third and fourth quarters of 2014 Glu adjusted a portion of its deferred tax asset valuation allowance as a result of the deferred tax liabilities recorded in connection with the Cie Games acquisition. Glu believes that these non-recurring, one-time tax adjustments do not reflect its ongoing operations and that investors benefit from a supplemental non-GAAP financial measure that excludes these adjustments.

Foreign currency exchange gains and losses. Foreign currency exchange gains and losses represent the net gain or loss that Glu has recorded for the impact of currency exchange rate movements on cash and other assets and liabilities denominated in foreign currencies related to the revaluation of assets and liabilities. Accordingly, foreign currency exchange gains and losses are generally unpredictable and can cause Glu’s reported results to vary significantly. Due to the unusual magnitude of these gains and losses, and the fact that Glu has not engaged in hedging or taken other actions to reduce the likelihood of incurring a sizeable net gain or loss in future periods, Glu began, with the quarter ended December 31, 2008, to present non-GAAP net loss and net loss per share excluding foreign exchange gains and losses for comparability purposes. Glu believes that these gains and losses do not reflect its ongoing operations and that investors benefit from a supplemental non-GAAP financial measure that excludes these items, enabling investors to compare Glu’s core operating results in different periods without this variability. Foreign exchange losses recognized during 2014 and 2015 were as follows (in thousands):
