Non-GAAP Financial Measures

To supplement its consolidated financial statements, which are prepared and presented in accordance with GAAP, Appian provides investors with certain non-GAAP financial measures, including non-GAAP operating loss, non-GAAP net loss, non-GAAP net loss per share,  non-GAAP weighted average shares outstanding and adjusted EBITDA. These non-GAAP financial measures exclude the effect of stock-based compensation expense and gain or loss on disposal of an asset. The presentation of these 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, and Appian’s non-GAAP measures may be different from non-GAAP measures used by other companies. For more information on these non-GAAP financial measures, please see the reconciliation of these non-GAAP financial measures to their nearest comparable GAAP measures at the end of this press release.  A reconciliation of non-GAAP guidance measures to the most comparable GAAP measures is not available on a forward-looking basis without unreasonable efforts due to the high variability, complexity and low visibility with respect to the charges excluded from these non-GAAP measures.

Appian uses these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. Appian’s management believes that these non-GAAP financial measures provide meaningful supplemental information regarding Appian’s performance by excluding certain expenses that may not be indicative of its recurring core business operating results. Appian believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing Appian’s performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to historical performance as well as comparisons to competitors’ operating results. Appian believes these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to measures used by management in its financial and operational decision-making and (2) they are used by Appian’s institutional investors and the analyst community to help them analyze the health of Appian’s business.
