Recent Business Highlights

Announced that Zscaler Internet Access™ achieved Federal Risk and Authorization Management Program (FedRAMP) High Authority to Operate from the FedRAMP Joint Authorization Board (JAB). Zscaler Internet Access is currently the only Secure Access Service Edge (SASE) Trusted Internet Connections (TIC) 3.0 solution that has achieved FedRAMP’s highest authorization to meet civilian agencies’ high security requirements, the Department of Defense (DoD), and other related intelligence organizations
Released the findings of its annual VPN Risk Report, which shows a growing number of VPN-specific security threats and a need for Zero Trust security architecture in enterprise-level organizations. Despite high awareness of VPN risks, remote working forced many companies to rely more heavily on legacy access methods during the pandemic. As a result, cybercriminals continue to take advantage of security vulnerabilities and increased attacks on enterprises using VPNs.
Announced the acquisition of ShiftRight, a leader in closed loop security workflow automation. ShiftRight’s workflow automation technology is currently being integrated into the Zscaler platform to automate security management for the growing influx of risks and incidents organizations are experiencing. It will provide a simple, sophisticated solution to reduce incident resolution time dramatically.
Introduced new data protection innovations that build upon a rich heritage of securing data across all cloud apps for data in motion, data at rest, and BYOD assets with unprecedented accuracy and scale. The new advancements accelerate data protection programs from months to hours with zero configuration for data loss prevention (DLP) and mitigates security risks by unifying data protection across all channels—simplifying operations by automating workflows.

Recently Issued Accounting Pronouncements

Effective August 1, 2022, the beginning of our fiscal year ending July 31, 2023, we adopted Accounting Standards Update No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40), using the modified retrospective transition method. The adoption of this standard resulted in the elimination of the debt discount and related amortization as interest expense and the classification of the portion of the debt issuance costs initially allocated to equity within the carrying amount of our senior convertible debt, which will be amortized as interest expense. Additionally, ASU 2020-06 amended the calculation of diluted earnings per share for certain convertible debt instruments, eliminating the treasury stock method and requiring the use of the if-converted method to compute the underlying potentially diluted shares. Accordingly, to account for the potentially diluted shares related to our senior convertible notes, we are required to add back the non-GAAP interest expense to our non-GAAP net income and include approximately 7.63 million shares related to our senior convertible notes beginning in our first quarter of fiscal year 2023.

Financial Outlook

For the second quarter of fiscal 2023, we expect:

Total revenue of $364 million to $366 million
Non-GAAP income from operations of $42 million to $43 million
Non-GAAP net income per share of approximately $0.29 to $0.30, assuming approximately 156 million common shares outstanding using the "if-converted" method for our senior convertible notes

For the full year fiscal 2023, we expect:

Total revenue of approximately $1.525 billion to $1.530 billion
Calculated billings of $1.930 billion to $1.940 billion. First half mix of billings to be approximately 43% of full-year
Non-GAAP income from operations of $179 million to $183 million
Non-GAAP net income per share of $1.23 to $1.25, assuming approximately 157 million common shares outstanding using the "if-converted" method for our senior convertible notes

These statements are forward-looking and actual results may differ materially. Refer to the Forward-Looking Statements safe harbor below for information on the factors that could cause our actual results to differ materially from these forward-looking statements.

Guidance for non-GAAP income from operations excludes stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets, amortization of debt discount and issuance costs. As a result of the adoption of ASU 2020-06 on August 1, 2022, guidance for non-GAAP net income per share uses the if-converted method to calculate the potentially diluted shares related to the convertible senior notes. Accordingly, we are required to add back the non-GAAP interest expense to our non-GAAP net income and include approximately 7.63 million shares related to our senior convertible notes. Additionally, we include the anti-dilutive impact of the capped call transactions entered into in connection with the convertible senior notes. We have not reconciled our expectations to 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. 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.

⁽¹⁾ Effective August 1, 2022, we adopted ASU 2020-06 using the modified retrospective method under which prior period amounts have not been adjusted. The adoption of this standard resulted in the elimination of the debt discount and related amortization as interest expense and the classification of the portion of the debt issuance costs initially allocated to equity within the carrying amount of the senior convertible notes, which will be amortized as interest expense. Additionally, this standard amended the calculation of diluted earnings per share for certain convertible debt instruments, eliminating the treasury stock method and requiring the use of the if-converted method to compute the underlying potentially diluted shares. Accordingly, to account for the potentially diluted shares related to the senior convertible notes, we are required to add back the non-GAAP interest expense to our non-GAAP net income and include approximately 7.63 million shares related to the senior convertible notes beginning in our first quarter of fiscal year 2023.

⁽²⁾We use our GAAP provision for income taxes for purposes of determining our non-GAAP income tax expense. The difference between our GAAP and non-GAAP income tax expense represents the effects of stock-based compensation expense recognized in foreign jurisdictions. The income tax benefit related to stock-based compensation expense included in the GAAP provision for income taxes was not material for all periods presented.

⁽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 differing 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 notes and therefore are included in the calculation of non-GAAP diluted shares outstanding.

Explanation of Non-GAAP Financial Measures

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, 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 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 intangible assets acquired in business acquisitions and related income tax effects, if applicable, are excluded because these are considered by management to be outside of our core business operating performance. Amortization of debt discount and issuance costs from the convertible senior notes are excluded because these are non-cash expenses and are not reflective of our ongoing operational performance. We estimate the tax effect of these items on our non-GAAP results and may adjust our GAAP provision for income taxes, if such effects have a material impact to our non-GAAP results.

Non-GAAP Financial Measures

Non-GAAP Gross Profit and Non-GAAP Gross Margin. We define non-GAAP gross profit as GAAP gross profit excluding stock-based compensation expense and related employer payroll taxes and amortization expense of acquired intangible assets. We define non-GAAP gross margin as non-GAAP gross profit as a percentage of revenue.

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 and amortization expense of acquired intangible assets. 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, amortization of debt discount and issuance costs, and income tax effects generated by the effects of stock-based compensation expense recognized in foreign jurisdictions. We define non-GAAP net income per share, diluted, as non-GAAP net income plus the non-GAAP interest expense 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 total 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.
