Non-GAAP financial measures and reconciliations

To supplement Splunk’s consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States (“GAAP”), Splunk provides investors with certain non-GAAP financial measures, including non-GAAP operating loss, non-GAAP net loss, non-GAAP operating margin, and non-GAAP loss per share (collectively the “non-GAAP financial measures”). These non-GAAP financial measures exclude stock-based compensation expense and the change in fair value of certain preferred stock warrants previously issued by Splunk. In addition, non-GAAP financial measures include free cash flow, which represents cash from operations less purchases of property and equipment. The presentation of the non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. Splunk uses these non-GAAP financial measures for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. Splunk believes that these non-GAAP financial measures provide useful information about Splunk’s operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making. In addition, these non-GAAP financial measures facilitate comparisons to competitors’ operating results.

Splunk excludes stock-based compensation expense from its non-GAAP operating loss, non-GAAP net loss, non-GAAP operating margin and non-GAAP loss per share because such expense is non-cash in nature. Splunk excludes expense attributable to the change in fair value of certain preferred stock warrants from its non-GAAP financial measures because it is a non-recurring, non-cash expense. Splunk considers free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that can be used for strategic opportunities, including investing in Splunk’s business, making strategic acquisitions, and strengthening Splunk’s balance sheet.

There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by Splunk’s competitors, and exclude expenses that may have a material impact upon Splunk’s reported financial results. Further, stock-based compensation expense has been and will continue to be for the foreseeable future a significant recurring expense in Splunk’s business and an important part of the compensation provided to Splunk’s employees. The non-GAAP financial measures are meant to supplement, and be viewed in conjunction with, GAAP financial measures.

The following table reconciles Splunk’s non-GAAP results to Splunk’s GAAP results included in this press release.
