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 performance measures. Appian uses these non-GAAP financial performance measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. Appian’s management believes these non-GAAP financial measures provide meaningful supplemental information regarding Appian’s performance by excluding certain expenses that may not be indicative of our recurring core business operating results. Appian believes 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 institutional investors and the analyst community to help them analyze the health of Appian’s business.

The non-GAAP financial performance measures include the following: non-GAAP subscriptions cost of revenue, non-GAAP professional services cost of revenue, non-GAAP total cost of revenue, non-GAAP total operating expense, non-GAAP operating income, non-GAAP income tax expense, non-GAAP net income, and non-GAAP net income per share, basic and diluted. These non-GAAP financial performance measures exclude the effect of stock-based

compensation expense, unrealized foreign exchange rate gains and losses, certain non-ordinary litigation-related expenses consisting of legal and other professional fees associated with the Pegasystems cases (net of insurance reimbursements), or Litigation Expense, amortization of the judgment preservation insurance policy, or JPI Amortization, and lease impairments and lease-related charges associated with actions taken to reduce the footprint of our leased office spaces, or Lease Impairment and Lease-Related Charges. While some of these items may be recurring in nature and should not be disregarded in the evaluation of our earnings performance, it is useful to exclude such items when analyzing current results and trends compared to other periods as these items can vary significantly from period to period depending on specific underlying transactions or events that may occur. Therefore, while we may incur or recognize these types of expenses in the future, we believe removing these items for purposes of calculating our non-GAAP financial measures provides investors with a more focused presentation of our ongoing operating performance.

Appian also discusses adjusted EBITDA, a non-GAAP financial performance measure it believes offers a useful view of the overall operation of its businesses. Appian defines adjusted EBITDA as net loss before (1) other income, net, (2) interest expense, (3) income tax expense, (4) depreciation expense and amortization of intangible assets, (5) stock-based compensation expense, (6) Litigation Expense, (7) JPI Amortization, and (8) Lease Impairment and Lease-Related Charges. The most directly comparable GAAP financial measure to adjusted EBITDA is net loss. Users should consider the limitations of using adjusted EBITDA, including the fact this measure does not provide a complete depiction of our operating performance. Adjusted EBITDA is not intended to purport to be an alternative to net loss as a measure of operating performance or to cash flows from operating activities as a measure of liquidity.

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 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, see the reconciliation of these non-GAAP financial measures to their nearest comparable GAAP measures at the end of this press release.

Appian provides guidance ranges for non-GAAP net income (loss) per share and adjusted EBITDA; however, we are not able to reconcile these amounts to their comparable GAAP financial measures without unreasonable efforts because certain information necessary to calculate such measures on a GAAP basis is unavailable, subject to high variability, dependent on future events outside of our control, and cannot be predicted. In addition, Appian believes such reconciliations could imply a degree of precision that might be confusing or misleading to investors. The actual effect of the reconciling items that Appian may exclude from these non-GAAP expense numbers, when determined, may be significant to the calculation of the comparable GAAP measures.

It is not possible for Appian’s management to predict all risks, nor can Appian assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements Appian may make.
