Guidance for non-GAAP income from operations and non-GAAP net income per share exclude, as applicable, stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets and amortization of debt issuance costs. We have not reconciled our expectations of non-GAAP income from operations and non-GAAP net income per share to their most directly comparable GAAP measures because certain items are out of our control or cannot be reasonably predicted. For those reasons, we are also unable to address the probable significance of the unavailable information, the variability of which may have a significant impact on future results. Accordingly, a reconciliation for the guidance for non-GAAP income from operations and non-GAAP net income per share is not available without unreasonable effort. There is no GAAP measure that is comparable to ARR, so we have not reconciled the ARR data included to any GAAP measure.

This press release contains forward-looking statements that involve risks and uncertainties, including, but not limited to, statements regarding our future financial and operating performance, including our financial outlook for the first quarter of fiscal 2026 and full year fiscal 2026, and the expected impact of the Red Canary acquisition. There are a significant number of factors that could cause actual results to differ materially from statements made in this press release, including but not limited to: macroeconomic influences and instability, geopolitical events, operations and financial results and the economy in general; risks related to the use of AI in our platform; our ability to identify and effectively implement the necessary changes to address execution challenges; risks associated with managing our rapid growth, including fluctuations from period to period; our limited experience with new products and subscriptions and support introductions and the risks associated with new products and subscription and support offerings, including the discovery of software bugs; our ability to attract and retain new customers; the failure to timely develop and achieve market acceptance of new products and subscriptions as well as existing products and subscription and support; rapidly evolving technological developments in the market for network security products and subscription and support offerings and our ability to remain competitive; length of sales cycles; useful lives of our assets and other estimates; and general market, political, economic and business conditions.

We believe that the presentation of non-GAAP financial information provides important supplemental information to management and investors regarding financial and business trends relating to our financial condition and results of operations. For further information regarding why we believe that these non-GAAP measures provide useful information to investors, the specific manner in which management uses these measures, and some of the limitations associated with the use of these measures, please refer to the "Explanation of Non-GAAP Financial Measures" section of this press release.

⁽¹⁾ Effective August 1, 2024, the beginning of our fiscal year ending July 31, 2025, we are using a long-term projected non-GAAP tax rate of 23% for the purpose of determining our non-GAAP net income and non-GAAP net income per share to provide better consistency across interim reporting periods in fiscal 2025 and beyond. Given the significant growth of our business and non-GAAP operating income, we believe this change is necessary to better reflect the performance of our business. We will continue to assess the appropriate non-GAAP tax rate on a regular basis, which could be subject to changes for a variety of reasons, including the rapidly evolving global tax environment, significant changes in our geographic earnings mix, or other changes to our strategy or business operations. Prior period amounts have been recast to reflect this change.

⁽³⁾ The sum of the fully diluted earnings per share impact of individual reconciling items may not total to fully diluted non-GAAP net income per share due to the weighted-average shares used in computing the GAAP net loss per share differs from the weighted-average shares used in computing the non-GAAP net income per share, and due to rounding of the individual reconciling items. The GAAP net loss per share calculation uses a lower share count as it excludes potentially dilutive shares, which are included in calculating the non-GAAP net income per share.

⁽⁴⁾ We exclude the in-the-money portion of the convertible senior notes for non-GAAP weighted-average diluted shares as they are covered by our capped call transactions. Our outstanding capped call transactions are antidilutive under GAAP but are expected to mitigate the dilutive effect of the convertible senior notes, and therefore are included in the calculation of non-GAAP diluted shares outstanding. The capped calls have an antidilutive impact when the average stock price of our common stock in a given period is higher than their exercise price.

In addition to our results determined in accordance with generally accepted accounting principles in the United States of America ("GAAP"), we believe the following non-GAAP measures are useful in evaluating our operating performance. We use the following non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, as it has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In particular, free cash flow is not a substitute for cash provided by operating activities. Additionally, the utility of free cash flow as a measure of our liquidity is further limited as it does not represent the total increase or decrease in our cash balance for a given period. In addition, other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. A reconciliation of our historical non-GAAP financial measures to their most directly comparable financial measures stated in accordance with GAAP has been included in this press release. Investors are cautioned that there are a number of limitations associated with the use of non-GAAP financial measures and key metrics as analytical tools. Investors are encouraged to review these reconciliations, and not to rely on any single financial measure to evaluate our business.

Stock-based compensation expense is excluded primarily because it is a non-cash expense that management believes is not reflective of our ongoing operational performance. Employer payroll taxes related to stock-based compensation, which is a cash expense, are excluded because these are tied to the timing and size of the exercise or vesting of the underlying equity incentive awards and the price of our common stock at the time of vesting or exercise, which may vary from period to period independent of the operating performance of our business. Amortization expense of acquired intangible assets and amortization of debt issuance costs from the convertible senior notes are excluded because these are non-cash expenses and are not reflective of our ongoing operational performance. Acquisition-related expenses incurred with business acquisitions are excluded because these are not reflective of our ongoing operations. Restructuring and other charges includes severance and termination benefits in connection with a restructuring plan to streamline operations and to align people, roles and projects to our strategic priorities. These expenses are excluded because they fluctuate in amount and frequency and are not reflective of our core business operating performance.

Effective August 1, 2024, the beginning of our fiscal year ending July 31, 2025, we are using a long-term projected non-GAAP tax rate of 23% for the purpose of determining our non-GAAP net income and non-GAAP net income per share to provide better consistency across interim reporting periods. Given the significant growth of our business and non-GAAP operating income, we believe this change is necessary to better reflect the performance of our business. We will continue to assess the appropriate non-GAAP tax rate on a regular basis, which could be subject to changes for a variety of reasons, including the rapidly evolving global tax environment, significant changes in our geographic earnings mix, or other changes to our strategy or business operations. Prior period amounts have been recast to reflect this change.

Non-GAAP Income from Operations and Non-GAAP Operating Margin. We define non-GAAP income from operations as GAAP loss from operations excluding stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets, restructuring and other charges and acquisition-related expenses. We define non-GAAP operating margin as non-GAAP income from operations as a percentage of revenue.

Non-GAAP Net Income per Share, Diluted. We define non-GAAP net income as GAAP net loss excluding stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets, restructuring and other charges, amortization of debt issuance costs, acquisition-related expenses and the non-GAAP provision for income taxes adjustment. We define non-GAAP net income per share, diluted, as non-GAAP net income plus the non-GAAP interest expense related to the convertible senior notes divided by the weighted-average diluted shares outstanding, which includes the effect of potentially diluted common stock equivalents outstanding during the period and the anti-dilutive impact of the capped call transactions entered into in connection with the convertible senior notes.

Calculated Billings. We define calculated billings as revenue plus the change in deferred revenue in a period. Calculated billings in any particular period aims to reflect amounts invoiced for subscriptions to access our cloud platform, together with related support services for our new and existing customers. We typically invoice our customers annually in advance, and to a lesser extent quarterly in advance, monthly in advance or multi-year in advance.

Free Cash Flow and Free Cash Flow Margin. We define free cash flow as net cash provided by operating activities less purchases of property, equipment and other assets and capitalized internal-use software. We define free cash flow margin as free cash flow divided by revenue. We believe that free cash flow and free cash flow margin are useful indicators of liquidity that provide information to management and investors about the amount of cash generated from our operations that, after the investments in property, equipment and other assets and capitalized internal-use software, can be used for strategic initiatives.
