Outlook

As of February 10, 2022, Zendesk provided guidance for the quarter ending March 31, 2022 and for the year ending December 31, 2022.

For the quarter ending March 31, 2022, Zendesk expects to report:

• Revenue in the range of $381 - 387 million
• GAAP operating income (loss) in the range of $(65) - (59) million, which includes share-based compensation and related expenses of approximately $72 million, acquisition-related expenses of approximately $11 million, and amortization of purchased intangibles of approximately $2 million
• Non-GAAP operating income in the range of $20 - 26 million, which excludes share-based compensation and related expenses of approximately $72 million, acquisition-related expenses of approximately $11 million, and amortization of purchased intangibles of approximately $2 million
• Approximately 122 million weighted average shares outstanding (basic)
• Approximately 135 million weighted average shares outstanding (diluted), which is impacted by the adoption of a new accounting standard related to the treatment of convertible debt

For the full year ending December 31, 2022, Zendesk expects to report:

• Revenue in the range of $1.675 - 1.705 billion
• GAAP operating income (loss) in the range of $(221) - (201) million, which includes share-based compensation and related expenses of approximately $317 million, acquisition-related expenses of approximately $14 million, and amortization of purchased intangibles of approximately $7 million
• Non-GAAP operating income in the range of $117 - 137 million, which excludes share-based compensation and related expenses of approximately $317 million, acquisition-related expenses of approximately $14 million, and amortization of purchased intangibles of approximately $7 million
• Approximately 124 million weighted average shares outstanding (basic)
• Approximately 137 million weighted average shares outstanding (diluted), which is impacted by the adoption of a new accounting standard related to the treatment of convertible debt
• Free cash flow in the range of $165 - 195 million

This free cash flow guidance includes expected transaction costs of $14 - 17 million related to the proposed merger with Momentive Global Inc. (“Momentive”). We expect to incur additional transaction costs if the proposed merger closes, which would reduce the free cash flow and GAAP operating income (loss) guidance provided above.

We have not reconciled free cash flow guidance to net cash from operating activities for the full year 2022 because we do not provide guidance on the reconciling items between net cash from operating activities and free cash flow, as a result of the uncertainty regarding, and the potential variability of, these items. The actual amount of such reconciling items will have a significant impact on our free cash flow and, accordingly, a reconciliation of net cash from operating activities to free cash flow for the full year 2022 is not available without unreasonable effort.

This guidance for diluted shares outstanding reflects the adoption of a new accounting standard in Q1 2022, which will increase the amount of diluted shares related to our convertible debt. Please refer to “About Non-GAAP Financial Measures” below for further details.

Zendesk’s estimates of share-based compensation and related expenses, amortization of purchased intangibles, acquisition-related expenses, weighted average shares outstanding, and free cash flow in future periods assume, among other things, the occurrence of no additional acquisitions, investments or restructurings, and no further revisions to share-based compensation and related expenses.

Shareholder Letter and Conference Call Information

The detailed Shareholder Letter is available at https://investor.zendesk.com and Zendesk will host a live video webcast at 2:00 p.m. Pacific Time (5:00 p.m. Eastern Time) on Thursday, February 10, 2022 to discuss the results. The live video webcast can be accessed through Zendesk’s investor relations website at https://investor.zendesk.com. A replay of the webcast will be available for 12 months.

About Non-GAAP Financial Measures

To provide investors and others with additional information regarding Zendesk’s results, the following non-GAAP financial measures were disclosed: non-GAAP gross profit and gross margin, non-GAAP operating expenses, non-GAAP operating income (loss) and operating margin, non-GAAP net income (loss), non-GAAP net income (loss) per share, basic and diluted, free cash flow, and free cash flow margin.

Specifically, Zendesk excludes the following from its historical and prospective non-GAAP financial measures, as applicable:

Share-Based Compensation and Amortization of Share-Based Compensation Capitalized in Internal-Use Software: Zendesk utilizes share-based compensation to attract and retain employees. It is principally aimed at aligning their interests with those of its stockholders and at long-term retention, rather than to address operational performance for any particular period. As a result, share-based compensation expenses vary for reasons that are generally unrelated to financial and operational performance in any particular period.

Employer Tax Related to Employee Stock Transactions: Zendesk views the amount of employer taxes related to its employee stock transactions as an expense that is dependent on its stock price, employee exercise and other award disposition activity, and other factors that are beyond Zendesk’s control. As a result, employer taxes related to its employee stock transactions vary for reasons that are generally unrelated to financial and operational performance in any particular period.

Amortization of Purchased Intangibles: Zendesk views amortization of purchased intangible assets, including the amortization of the cost associated with an acquired entity’s developed technology, as items arising from pre-acquisition activities determined at the time of an acquisition. While these intangible assets are evaluated for impairment regularly, amortization of the cost of purchased intangibles is an expense that is not typically affected by operations during any particular period.

Acquisition-Related Expenses: Zendesk views acquisition-related expenses, such as transaction costs, integration costs, restructuring costs, and acquisition-related retention payments, including amortization of acquisition-related retention payments capitalized in internal-use software, as not necessarily reflective of operational performance during a period. Accordingly, Zendesk believes the consideration of measures that exclude such expenses can assist in the comparison of operational performance in different periods which may or may not include such expenses. Acquisition-related expenses include costs associated with Zendesk's proposed acquisition of Momentive.

Real Estate Impairments: To support an increased percentage of remote teams, Zendesk records impairments for certain assets associated with leased properties, or portions thereof, that it ceases to occupy. Any losses and gains associated with these activities are generally unrelated to financial and operational performance in any particular period and Zendesk believes the exclusion of such losses and gains provides for a more useful comparison of operational performance in comparative periods that may or may not include such losses and gains.

Loss on Early Extinguishment of Debt: In March 2018, Zendesk issued $575 million aggregate principal amount of 0.25% convertible senior notes due in 2023 (the "2023 Notes"). In June 2020, Zendesk issued $1,150 million aggregate principal amount of 0.625% convertible senior notes due in 2025 (the "2025 Notes"). In connection with the offering of the 2025 Notes, Zendesk used $618 million of the net proceeds from the offering of the 2025 Notes to repurchase $426 million aggregate principal amount of the 2023 Notes in cash through individual privately negotiated transactions (the "2023 Notes Partial Repurchase"). Of the $618 million consideration, $393 million and $225 million were allocated to the debt and equity components, respectively. As of the repurchase date, the carrying value of the 2023 Notes subject to the 2023 Notes Partial Repurchase, net of unamortized debt discount and issuance costs, was $367 million. The 2023 Notes Partial Repurchase resulted in a $26 million loss on early debt extinguishment. As of December 31, 2021, $149 million of principal remains outstanding on the 2023 Notes. The loss on early extinguishment of debt is a non-cash item, and we believe the exclusion of this expense will provide for a more useful comparison of our operational performance in different periods.

Amortization of Debt Discount and Issuance Costs: The imputed interest rates of the 2023 Notes and the 2025 Notes were approximately 5.26% and 5.00%, respectively. This is a result of the debt discounts recorded for the conversion features of the Notes that are required to be separately accounted for as equity, and debt issuance costs, which reduce the carrying value of the convertible debt instruments. The debt discounts are amortized as interest expense together with the issuance costs of the debt. The expense for the amortization of debt discount and debt issuance costs is a non-cash item, and we believe the exclusion of this interest expense will provide for a more useful comparison of our operational performance in different periods.

Income Tax Effects: Zendesk utilizes a fixed long-term projected tax rate in its computation of non-GAAP income tax effects to provide better consistency across interim reporting periods. In projecting this long-term non-GAAP tax rate, Zendesk utilizes a financial projection that excludes the direct impact of other non-GAAP adjustments. The projected rate considers other factors such as Zendesk's current operating structure, existing tax positions in various jurisdictions, and key legislation in major jurisdictions where Zendesk operates. For the year ended December 31, 2021, Zendesk has determined the projected non-GAAP tax rate to be 21%. Zendesk will periodically re-evaluate this tax rate, as necessary, for significant events, based on relevant tax law changes, material changes in the forecasted geographic earnings mix, and any significant acquisitions.

Zendesk provides disclosures regarding its free cash flow, which is defined as net cash from operating activities, plus repayment of convertible senior notes attributable to debt discount, less purchases of property and equipment and internal-use software development costs. Free cash flow margin is calculated as free cash flow as a percentage of total revenue. Zendesk uses free cash flow, free cash flow margin, and other measures, to evaluate the ability of its operations to generate cash that is available for purposes other than capital expenditures and capitalized software development costs. Zendesk believes that information regarding free cash flow and free cash flow margin provides investors with an important perspective on the cash available to fund ongoing operations.

Zendesk has not reconciled free cash flow guidance to net cash from operating activities for the year ending December 31, 2022 because Zendesk does not provide guidance on the reconciling items between net cash from operating activities and free cash flow, as a result of the uncertainty regarding, and the potential variability of, these items. The actual amount of such reconciling items will have a significant impact on Zendesk’s free cash flow and, accordingly, a reconciliation of net cash from operating activities to free cash flow for the year ending December 31, 2022 is not available without unreasonable effort.

Zendesk does not provide a reconciliation of its non-GAAP operating margin guidance to GAAP operating margin for future periods beyond the current fiscal year because Zendesk does not provide guidance on the reconciling items between GAAP operating margin and non-GAAP operating margin for such periods, as a result of the uncertainty regarding, and the potential variability of, these items. The actual amount of such reconciling items will have a significant impact on Zendesk’s non-GAAP operating margin and, accordingly, a reconciliation of GAAP operating margin to non-GAAP operating margin guidance for such periods is not available without unreasonable effort.

Zendesk’s disclosures regarding its expectations for its non-GAAP gross margin include adjustments to its expectations for its GAAP gross margin that exclude share-based compensation and related expenses in Zendesk’s cost of revenue, amortization of purchased intangibles primarily related to developed technology, and acquisition-related expenses. The share-based compensation and related expenses excluded due to such adjustments are primarily comprised of the share-based compensation and related expenses for employees associated with Zendesk’s infrastructure and customer experience organization.

Zendesk does not provide a reconciliation of its non-GAAP gross margin guidance to GAAP gross margin for future periods because Zendesk does not provide guidance on the reconciling items between GAAP gross margin and non-GAAP gross margin, as a result of the uncertainty regarding, and the potential variability of, these items. The actual amount of such reconciling items will have a significant impact on Zendesk’s non-GAAP gross margin and, accordingly, a reconciliation of GAAP gross margin to non-GAAP gross margin guidance for the period is not available without unreasonable effort.

Zendesk uses non-GAAP financial information to evaluate its ongoing operations and for internal planning and forecasting purposes. Zendesk’s management does not itself, nor does it suggest that investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Zendesk presents such non-GAAP financial measures in reporting its financial results to provide investors with an additional tool to evaluate Zendesk’s operating results. Zendesk believes these non-GAAP financial measures are useful because they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making. This allows investors and others to better understand and evaluate Zendesk’s operating results and future prospects in the same manner as management.

Zendesk’s management believes it is useful for itself and investors to review, as applicable, both GAAP information that may include items such as share-based compensation and related expenses, amortization of debt discount and issuance costs, amortization of purchased intangibles, acquisition-related expenses, loss on early extinguishment of debt, and real estate impairments, and the non-GAAP measures that exclude such information in order to assess the performance of Zendesk’s business and for planning and forecasting in subsequent periods. When Zendesk uses such a non-GAAP financial measure with respect to historical periods, it provides a reconciliation of the non-GAAP financial measure to the most closely comparable GAAP financial measure. When Zendesk uses such a non-GAAP financial measure in a forward-looking manner for future periods, and a reconciliation is not determinable without unreasonable effort, Zendesk provides the reconciling information that is determinable without unreasonable effort and identifies the information that would need to be added or subtracted from the non-GAAP measure to arrive at the most directly comparable GAAP measure. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measure as detailed above.

In August 2020, the Financial Accounting Standards Board issued ASU 2020-06, regarding ASC Topic 470 “Debt” and ASC Topic 815 “Derivatives and Hedging,” which amends the calculation of diluted earnings per share for certain convertible debt instruments, among other changes. Under the new standard, Zendesk will be required to use the “if-converted” method to calculate diluted earnings per share for its convertible debt, which assumes conversion of its convertible debt instruments at the beginning of the reporting period, with settlement entirely in shares of common stock, unless the result would be antidilutive. Historically, Zendesk calculated diluted earnings per share for its convertible debt using the “treasury stock” method, which assumes that the principal amount of convertible debt instruments is settled in cash. Accordingly, our diluted shares outstanding will increase under the new standard. We plan to adopt this standard in the first quarter of 2022. The total amount of shares underlying the convertible notes is approximately 13 million.

About Operating Metrics

Zendesk reviews a number of operating metrics to evaluate its business, measure performance, identify trends, formulate business plans, and make strategic decisions. These include the number of logos, dollar-based net expansion rate, annual recurring revenue, the percentage of its annual recurring revenue from customer accounts with more than $250,000 in annual recurring revenue and number of customer accounts with more than $1 million in annual recurring revenue.

Zendesk's number of logos is a consolidation of paid customer accounts across our solutions, exclusive of Zendesk's legacy Starter plan, free trials, or other free services, as of the end of the period. A paid customer account is one individual billing relationship for subscription to our services. Zendesk calculates its logo number by consolidating paid customer accounts that share common corporate information as a single organization or customer may have multiple paid customer accounts across its solutions to service separate subsidiaries, divisions, or work processes. As of December 31, 2021, Zendesk had approximately 111,100 logos. Zendesk does not currently include in its logo metric logos associated with its legacy analytics product, its legacy Outbound product, its legacy Starter plan, its Sell product, Sunshine Conversations, its legacy Smooch product, free trials, or other free services. We may from time to time refer to "customers" or "brands" in our publicly-available disclosures, each of which refers to our number of logos.

Zendesk’s dollar-based net expansion rate provides a measurement of our ability to increase revenue across our existing customer base through expansion of authorized agents associated with a logo, upgrades in subscription plans, and the purchase of additional products as offset by contraction and churn in authorized agents associated with a logo, and downgrades in subscription plans. Zendesk does not currently incorporate operating metrics associated with its legacy analytics product, its legacy Outbound product, its legacy Starter plan, its legacy Sell product, legacy Sunshine Conversations, its legacy Smooch product, free trials, or other free services into its measurement of dollar-based net expansion rate. Dollar-based net expansion rate is based upon our annual recurring revenue for a set of logos on Zendesk's products. Annual recurring revenue is determined by multiplying monthly recurring revenue by 12. Monthly recurring revenue is a legal and contractual determination made by assessing the contractual terms, as of the date of determination, as to the revenue we expect to generate in the next monthly period, assuming no changes to the subscription and without taking into account any usage above the subscription base, if any, that may be applicable to such subscription. Zendesk excludes the impact of revenue that it expects to generate from fixed-term contracts that are each associated with an existing account, are solely for additional temporary agents, and are not contemplated to last for the duration of the primary contract for the existing account from its determination of monthly recurring revenue. Zendesk additionally excludes the impact of accounts that are free-trial accounts that did not result in paid subscriptions, and temporary coupons, such as short-term discounts that were applied to certain accounts due to the COVID-19 pandemic, from its annual recurring revenue. Monthly recurring revenue is not determined by reference to historical revenue, deferred revenue, or any other United States generally accepted accounting principles, or GAAP, financial measure over any period.

Zendesk calculates its dollar-based net expansion rate by dividing the retained revenue net of contraction and churn by Zendesk’s base revenue. Zendesk defines its base revenue as the aggregate annual recurring revenue across its products from logos as of the date one year prior to the date of calculation. Zendesk defines the retained revenue net of contraction and churn as the aggregate annual recurring revenue across its products for the same customer base included in the measure of base revenue at the end of the annual period being measured.

For a more detailed description of how Zendesk calculates its dollar-based net expansion rate, please refer to Zendesk’s periodic reports filed with the Securities and Exchange Commission.

Zendesk’s percentage of annual recurring revenue that is generated by customer accounts with more than $250,000 in annual recurring revenue is determined by dividing the total annual recurring revenue from customer accounts with more than $250,000 in annual recurring revenue from our products other than Sell and Sunshine Conversations as of the measurement date by the total annual recurring revenue for all customer accounts from our products other than Sell and Sunshine Conversations as of the measurement date. Zendesk determines the customer accounts with $250,000 in annual recurring revenue as of the measurement date based on the annual recurring revenue of a customer account at the measurement date. A "customer account" is based on an identifier tracked in our internal sales system as a separate and distinct buying entity.

Zendesk’s determines the number of customer accounts with more than $1 million in annual recurring revenue as of the measurement date based on the annual recurring revenue of a customer account (as defined above) at the measurement date.

Zendesk determines its bookings as the incremental additional annual recurring revenue from contracts that were entered into during the referenced fiscal quarter. Zendesk determines its net bookings as bookings less any annual recurring revenue lost from contracts which have not been renewed or a decrease in the level of paid services with our solutions over the referenced fiscal quarter.

Zendesk's annual revenue run rate is based on its revenue for the most recent applicable quarter. Zendesk annualizes such results to estimate its annual revenue run rate by multiplying the revenue for its most recent applicable quarter by four. Zendesk's annual revenue run rate is not a comprehensive statement of its financial results for such period and should not be viewed as a substitute for full annual or interim financial statements prepared in accordance with GAAP. In addition, Zendesk's revenue for the most recent applicable quarter or annual revenue run rate are not necessarily indicative of the results to be achieved in any future period.

Zendesk determines its average deal size by dividing the annual recurring revenue from bookings for our products other than Sell and Sunshine Conversations in a quarter by the number of deals that were entered into during that quarter.
