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 historical 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.

· Adjustment to the value of redeemable non-controlling interest to the redemption amount is excluded as the company believes it may not be indicative of future operating results and that investors benefit from an understanding of the company’s operating results without giving effect to this adjustment.

Additionally, the Company believes the following supplemental non-GAAP financial information are useful to investors and others in assessing its operating performance. A calculation of these supplemental non-GAAP financial information have been provided in the table titled ‘Non-GAAP Supplemental financial information’.

· Calculated billings is calculated as revenue plus the change in total deferred revenue as presented on the balance sheet.

· Free cash flow is calculated as cash flow provided by (used in) operations less the purchase of property and equipment and capitalized software development costs presented on the statement of cash flows.

Management believes calculated billings offers investors useful supplemental information regarding the performance of our business, and will help investors better understand the sales volumes and performance of our business. Free cash flow metrics is useful as it provides investors an enhanced view of the company’s operational performance and the cash available to fund on-going operations. The presentation of non-GAAP free cash flow is not meant to be considered in isolation or as an alternative to net income as an indicator of our performance, or as an alternative to cash flows from operating activities as a measure of liquidity.

The company encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between GAAP and non-GAAP results are presented in the tables of this release.
