Use of Non-GAAP Financial Information

Marketo provides financial statements that are prepared in accordance with generally accepted accounting principles (GAAP). To help understand Marketo’s past financial performance and future results, Marketo has supplemented its financial results that it provides in accordance with GAAP with certain non-GAAP financial measures. The method Marketo uses to produce non-GAAP financial results is not computed according to GAAP and may differ from the methods used by other companies. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with the company’s consolidated financial statements prepared in accordance with GAAP.  Specifically, management is excluding the following items from its non-GAAP historic and estimated net loss and net loss per common share, basic and diluted:

· Stock-Based Compensation Expenses: The company’s compensation strategy includes the use of stock-based compensation to attract and retain employees and executives. It is principally aimed at aligning their interests with those of our stockholders and at long-

term employee retention, rather than to motivate or reward operational performance for any particular period. Thus, stock-based compensation expense varies for reasons that are generally unrelated to operational decisions and performance in any particular period.

· Amortization of Acquired Intangible Assets: The company views amortization of acquisition-related intangible assets, such as the amortization of the cost associated with an acquired company’s research and development efforts, trade names, customer lists and customer relationships, as items arising from pre-acquisition activities determined at the time of an acquisition. While these intangible assets are continually evaluated for impairment, amortization of the cost of purchased intangibles is a static expense, one that is not typically affected by operations during any particular period.
