Non-GAAP Financial Measures

We believe that providing non-GAAP financial measures that exclude, as applicable, share-based compensation expense and certain non-recurring costs, as well as, the tax effect of these non-GAAP adjustments, allows for more meaningful comparisons between our operating results from period to period. These non-GAAP financial measures are an important tool for financial and operational decision-making and for evaluating our operating results over different periods:

•

We define non-GAAP gross profit as gross profit excluding share-based compensation expense.

•

We define non-GAAP operating income (loss) as operating income (loss) excluding share-based compensation expense and one-time expenses associated with reorganization in of one of our subsidiaries.

•

We define non-GAAP net income as net income excluding share-based compensation expense, one-time expenses associated with reorganization in of one of our subsidiaries and the tax effect of these non-GAAP adjustments.

Because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact a company’s non-cash expense, we believe that providing non-GAAP financial measures that exclude non-cash share-based compensation expense allow for more meaningful comparisons between our operating results from period to period. In addition, we believe that providing non-GAAP financial measures that exclude one-time expenses associated with the reorganization of one of our subsidiaries allows for more meaningful comparisons between our operating results from period to period since these non-recurring costs are not representative or indicative of our ongoing operations. We also believe that the tax effects related to the non-GAAP adjustments set forth above do not reflect the performance of our core business and would impact period-to-period comparability.

Other companies, including companies in our industry, may calculate non-GAAP gross profit, non-GAAP operating income (loss) and non-GAAP net income (loss) differently or not at all, which reduces the usefulness these non-GAAP financial measures for comparison. You should consider these non-GAAP financial measures along with other financial performance measures, including gross profit, operating income (loss) and net income (loss), and our financial results presented in accordance with U.S. GAAP. Tufin urges investors to review the reconciliation of its non-GAAP financial measures to the comparable U.S. GAAP financial measures included below, and not to rely on any single financial measure to evaluate its business.

Guidance for non-GAAP financial measures excludes, as applicable, share-based compensation expense and certain non-recurring costs, as applicable. A reconciliation of the non-GAAP financial measures guidance to the corresponding GAAP measures is not available on a forward-looking basis due to the uncertainty regarding, and the potential variability and significance of, the amounts of share-based compensation expense and certain non-recurring costs, as applicable, that are excluded from the guidance. Accordingly, a reconciliation of the non-GAAP financial measures guidance to the corresponding GAAP measures for future periods is not available without unreasonable effort.
