Financial Outlook
Palo Alto Networks provides guidance based on current market conditions and expectations.
For the fiscal first quarter 2027, we expect:
- Next-Generation Security ARR of $9.54 billion to $9.56 billion, representing year-over-year growth of 63%.
- Remaining performance obligations of $20.8 billion to $20.9 billion, representing year-over-year growth of 34% to 35%.
- Total revenue in the range of $3.300 billion to $3.310 billion, representing year-over-year growth of 33% to 34%.
- Diluted non-GAAP net income per share in the range of $0.96 to $0.98, using 837 million to 844 million shares outstanding.
For the fiscal year 2027, we expect:
- Next-Generation Security ARR of $11.075 billion to $11.175 billion, representing year-over-year growth of 22% to 23%.
- Remaining performance obligations of $25.2 billion to $25.4 billion, representing year-over-year growth of 19% to 20%.
- Total revenue in the range of $14.10 billion to $14.20 billion, representing year-over-year growth of 23% to 24%.
- Non-GAAP operating margin of 29.5%.
- Diluted non-GAAP net income per share in the range of $4.16 to $4.19, using 844 million to 847 million shares outstanding.
- Adjusted free cash flow margin to be 38.0%.
Guidance for non-GAAP financial measures excludes share-based compensation-related charges, including share-based payroll tax expense, acquisition-related costs, including change in fair value of contingent consideration liability, amortization expense of acquired intangible assets, litigation-related charges, non-cash charges related to convertible notes, change in fair value of convertible senior notes and capped calls, and income tax and other tax adjustments related to our long-term non-GAAP effective tax rate, along with certain non-recurring expenses and certain non-recurring cash flows. We have not reconciled non-GAAP operating margin guidance to GAAP operating margin, diluted non-GAAP net income per share guidance to GAAP net income (loss) per diluted share, or adjusted free cash flow margin guidance to GAAP net cash provided by operating activities because we do not provide guidance on GAAP operating margin, GAAP net income (loss) or net cash provided by operating activities and would not be able to present the various reconciling cash and non-cash items between GAAP and non-GAAP financial measures because certain items that impact these measures are uncertain or out of our control, or cannot be reasonably predicted, including share-based compensation expense, without unreasonable effort. The actual amounts of such reconciling items will have a significant impact on the company’s GAAP net income (loss) per diluted share, GAAP operating margin and GAAP net cash provided by operating activities.

All forward-looking statements in this press release are based on our current beliefs and information available to management as of the date hereof and are inherently uncertain, and we do not assume any obligation to update the forward-looking statements provided to reflect events that occur or circumstances that exist after the date on which they were made, except as required by law.
Non-GAAP Financial Measures and Other Key Metrics
Palo Alto Networks has provided in this press release financial information that has not been prepared in accordance with generally accepted accounting principles in the United States (GAAP). The company uses these non-GAAP financial measures and other key metrics internally in analyzing its financial results and believes that the use of these non-GAAP financial measures and key metrics are helpful to investors as an additional tool to evaluate ongoing operating results and trends, and in comparing the company’s financial results with other companies in its industry, many of which present similar non-GAAP financial measures or key metrics.
The presentation of these non-GAAP financial measures and key metrics are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the company’s consolidated financial statements prepared in accordance with GAAP. A reconciliation of the company’s historical non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included in this press release, and investors are encouraged to review these reconciliations.
Non-GAAP operating income. Palo Alto Networks defines non-GAAP operating income as operating income plus share-based compensation-related charges, including share-based payroll tax expense, acquisition-related costs, including change in fair value of contingent consideration liability, amortization expense of acquired intangible assets, and litigation-related charges. The company believes that non-GAAP operating income provides management and investors with greater visibility into the underlying performance of the company’s core business operating results.
Non-GAAP net income and net income per share, diluted. Palo Alto Networks defines non-GAAP net income as net income (loss) plus share-based compensation-related charges, including share-based payroll tax expense, acquisition-related costs, including change in fair value of contingent consideration liability, amortization expense of acquired intangible assets, litigation-related charges, non-cash charges related to convertible notes, and change in fair value of convertible senior notes and capped calls. The company also excludes from non-GAAP income tax and other tax adjustments related to our long-term non-GAAP effective tax rate in order to provide a complete picture of the company’s recurring core business operating results. The company defines non-GAAP net income per share, diluted, as non-GAAP net income divided by the weighted-average diluted shares outstanding, which includes the potentially dilutive effect of the company’s employee equity incentive plan awards and the company’s convertible senior notes and related warrants, after giving effect to the anti-dilutive impact of the company’s note hedge agreements and capped call transactions, which reduced the potential economic dilution that otherwise would have occurred in connection with the conversion and settlement of the company’s convertible senior notes. Under GAAP, the anti-dilutive impact of the note hedge or capped calls is not reflected in diluted shares outstanding. The company considers these non-GAAP financial measures to be useful metrics for management and investors for the same reasons that it uses non-GAAP operating income.
Adjusted free cash flow margin, adjusted free cash flow, and free cash flow. Palo Alto Networks defines adjusted free cash flow margin, a non-GAAP measure, as adjusted free cash flow divided by total revenue. The company defines adjusted free cash flow, a non-GAAP measure, as free cash flow, plus certain capital expenditures for our headquarters and certain corporate assets, plus payments of acquisition-related costs, plus litigation-related payments. The company defines free cash flow, a non-GAAP measure, as net cash provided by operating activities less purchases of property, equipment, and other assets. We consider free cash flow, adjusted free cash flow, and adjusted free cash flow margin to be operating metrics as well as liquidity measures that provide useful information to management and investors about the amount of cash generated by the business after necessary capital expenditures and before the impact of certain qualifying non-recurring cash payments from operating activities, as applicable. A limitation of the utility of free cash flow or adjusted free cash flow as a measure of our liquidity is that it does not represent the total increase or decrease in our cash balance for the period. In addition, it is important to note that other companies, including companies in our industry, may not use free cash flow or adjusted free cash flow, may calculate free cash flow or adjusted free cash flow in a different manner than we do, or may use other financial measures to evaluate their liquidity, all of which could reduce the usefulness of free cash flow or adjusted free cash flow as a comparative measure.
Next-Generation Security ARR. Palo Alto Networks defines Next-Generation Security ARR as the annualized allocated revenue of all active contracts as of the final day of the reporting period related to all product, subscription and support offerings, excluding revenue from hardware products, and legacy attached subscriptions, support offerings and professional services. The company considers Next-Generation Security ARR to be a useful operating metric for management and investors to assess the performance of the company because Next-Generation Security is where the company has focused its innovation and the company expects its overall revenue to be disproportionately driven by this Next-Generation Security portfolio. Because Next-Generation Security ARR does not have the effect of providing a numerical measure that is different from any comparable GAAP measure, the company does not consider it a non-GAAP measure.
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. Many of the adjustments to the company’s GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in the company’s financial results for the foreseeable future, such as share-based compensation, which is an important part of Palo Alto Networks employees’ compensation and impacts their performance. Furthermore, these non-GAAP financial measures are not based on any standardized methodology prescribed by GAAP, and the components that Palo Alto Networks excludes in its calculation of non-GAAP financial measures may differ from the components that its peer companies exclude when they report their non-GAAP results of operations. As a result, these non-GAAP financial measures may not be directly comparable to similar non-GAAP financial measures used by other companies. Palo Alto Networks compensates for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures. In the future, the company may also exclude non-recurring expenses and other expenses that do not reflect the company’s core business operating results.
