EVERBRIDGE, INC. AND SUBSIDIARIES

Notes to the Condensed Consolidated Financial Statements

(Unaudited)

(1) Business and Nature of Operations

The Company has operations in the United States, United Kingdom, Norway, China, Netherlands, Canada, New Zealand, France, India, and other countries.

(2) Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

The condensed consolidated balance sheet as of December 31, 2021, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, statements of stockholders’ equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2022 or any future period.

Effective January 1, 2022, the Company adopted the requirements of Accounting Standards Update (“ASU”) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, as discussed in this Note 2 and Note 9.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Assets and liabilities which are subject to judgment and use of estimates include the determination of the period of benefit for deferred commissions, relative stand-alone selling price for identified performance obligations in the Company’s revenue transactions, allowances for credit losses, the fair value of assets acquired and liabilities assumed in business combinations, the fair value of contingent consideration, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, contingencies, and the valuation and assumptions underlying stock-based compensation. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, the Company engages valuation specialists to assist with management’s determination of the valuation of its fair values of assets acquired and liabilities assumed in business combinations, convertible senior notes, and certain market-based performance equity awards.

8

There have been significant changes to the global economic situation as a consequence of the COVID-19 pandemic. There continue to be uncertainties with respect to macroeconomic conditions as a result of the pandemic and otherwise and there may be future periods of global instability and volatility in markets where the Company conducts business which could cause changes to estimates as a result of the financial circumstances. Such changes to estimates could potentially result in impacts that would be material to the consolidated financial statements, particularly with respect to the timing of revenue recognition resulting from potential implementation delays, evaluating the recoverability of long-lived assets with finite useful lives for impairment and estimates of credit losses for accounts receivables and contract assets. No impairments were recorded as of the balance sheet date; however, due to significant uncertainty surrounding the situation, management's judgment regarding this could change in the future. As of the date of issuance of these financial statements, the Company’s results of operations have not been significantly impacted by the COVID-19 pandemic; however, the Company continues to monitor the situation.

Concentrations of Credit and Business Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable.

The Company maintains cash and cash equivalent balances at several banks. Accounts located in the United States are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. From time to time, balances may exceed amounts insured by the FDIC. The Company has not experienced any losses in such amounts.

The Company’s accounts receivable are generally unsecured and are derived from revenue earned from customers primarily located in the United States, Norway, Netherlands, Sweden and the United Kingdom and are generally denominated in U.S. Dollars, Norwegian Krone, Euro, Swedish Kronor or British Pounds. Each reporting period, the Company reevaluates each customer’s ability to satisfy credit obligations and maintains an allowance for credit risk based on the evaluations. No single customer comprised more than 10% of the Company’s total revenue for the three months ended March 31, 2022 and 2021. No single customer comprised more than 10% of the Company’s gross accounts receivable as of March 31, 2022. One customer comprised approximately 10% of the Company’s gross accounts receivable balance at December 31, 2021.  

Cash and Cash Equivalents

The Company considers all highly liquid instruments with original maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents consist of funds deposited into money market funds. Cash and cash equivalents are recorded at cost, which approximates fair value.

Restricted Cash

The Company’s restricted cash balance primarily consists of cash held at a financial institution for collateral against performance on the Company’s customer contracts and certain other cash deposits for specific purposes.

Significant Accounting Policies

There have been no changes to the Company’s significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 25, 2022, that have had a material impact on the Company’s condensed consolidated financial statements and related notes.

Revenue Recognition

The Company derives its revenues primarily from subscription services and professional services. Revenues are recognized when control of services is transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those services.

The Company determines revenue recognition through the following steps:

• Identification of the contract, or contracts, with a customer;

• Identification of the performance obligations in the contract;

• Determination of the transaction price;

• Allocation of the transaction price to the performance obligations in the contract; and

• Recognition of revenue when, or as, the Company satisfies a performance obligation.

9

Subscription Services Revenues

Subscription services revenues primarily consist of fees that provide customers access to one or more of the Company’s hosted applications for critical event management, with routine customer support. Revenue is generally recognized over time on a ratable basis over the contract term beginning on the date that the Company’s service is made available to the customer. All services are recognized using an output measure of progress looking at time elapsed as the contract generally provides the customer equal benefit throughout the contract period. The Company’s subscription contracts are generally two years or longer in length, billed annually in advance, and non-cancelable.

Professional Services Revenues

Professional services revenues primarily consist of fees for deployment and optimization services, as well as training. The majority of the Company’s consulting contracts revenue is recognized over time as the services are performed. For contracts billed on a fixed price basis, revenue is recognized over time based on the proportion performed.

Software License Revenues

The Company also sells software and related post contract support for on premises usage as well as professional services, hardware and hosting. The Company’s on premises license transactions are generally perpetual in nature and are recognized at a point in time when made available to the customer for use. Significant judgment is required to determine the standalone selling prices for each distinct performance obligation in order to allocate the transaction price for purposes of revenue recognition. Making this judgment of estimating a standalone selling price involves consideration of overall pricing objectives, market conditions and other factors, including the value of the Company’s other similar contracts, the applications sold, customer demographics, geographic locations, and the number and types of users within the Company’s contracts. The significant judgment was primarily due to using such considerations to estimate the price that each distinct performance obligation would be sold for on a standalone basis because such performance obligations are typically sold together on a bundled basis. Changes in these estimates of standalone selling prices can have a material effect on the amount of revenue recognized from each distinct performance obligation.

Contracts with Multiple Performance Obligations

Most of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis for those performance obligations with stable observable prices and then the residual method applied for any performance obligation that has pricing which is highly variable. The Company determines the standalone selling prices based on the Company’s overall pricing objectives, taking into consideration market conditions and other factors, including the value of the Company’s contracts, pricing when certain services are sold on a standalone basis, the applications sold, customer demographics, geographic locations, and the volume of services and users.

Returns

The Company does not offer rights of return for its products and services in the normal course of business. 

Customer Acceptance

The Company’s contracts with customers generally do not include customer acceptance clauses.

Trade and Other Receivables

Trade and other receivables are primarily comprised of trade receivables that are recorded at the invoice amount, net of an allowance for credit risk, which is not material. Other receivables represent unbilled receivables related to subscription and professional services contracts, net of an allowance for credit losses, which is not material.

Deferred Costs

Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Subscription-related commissions costs are deferred and then amortized on a straight-line basis over a period of benefit that the Company has determined to be four years. Sales commissions attributable to professional services are expensed within twelve months of selling the service to the customer. The Company has determined the period of benefit by taking into consideration its customer contracts, its technology and other factors. Sales commissions attributed to renewals are not material and are not commensurate with initial and growth sales. Amortization of deferred commissions is included in sales and marketing expenses in the accompanying condensed consolidated statements of operations.

10

Deferred Revenue

Deferred revenue consists of amounts that have been invoiced and for which the Company has the right to bill, but that have not been recognized as revenue because the related goods or services have not been transferred. Deferred revenue that will be realized during the succeeding 12-month period is recorded as current, and the remaining deferred revenue is recorded as non-current.

In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts generally do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, not to receive financing from its customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with revenue recognized ratably over the contract period.

Recently Adopted Accounting Pronouncements

ASU 2021-10

In November 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance. ASU 2021-10 requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The Company adopted ASU 2021-10 on January 1, 2022 on a prospective basis. The adoption of this standard did not have an impact on the Company’s condensed consolidated financial statements.

ASU 2021-04

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU 2021-04 requires accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after the modification or exchange based on the economic substance of the modification or exchange. The recognition of the modification depends on the nature of the transaction in which the equity-classified written call option is modified. If there is more than one element in a transaction (for example, if the modification involves both a debt modification and an equity issuance), then the guidance requires allocating the effect of the option modification to each element. The Company adopted ASU 2021-04 on January 1, 2022 on a prospective basis. The adoption of this standard did not have an impact on the Company’s condensed consolidated financial statements.

ASU 2020-06

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 reduces the number of accounting models for convertible instruments by eliminating two of the three models in Accounting Standards Codification (“ASC”) 470-20, Debt—Debt with Conversion and Other Options, that require separate accounting for embedded conversion features, amends the requirements for a contract that is potentially settled in an entity’s own shares to be classified in equity, and amends certain guidance on the computation of earnings per share for convertible instruments and contracts on an entity’s own equity. The Company adopted the standard on January 1, 2022 using the modified retrospective approach.

Upon adoption of ASU 2020-06, the Company no longer separately presents in equity the embedded conversion feature of the 0% convertible senior notes due March 15, 2026 (the “2026 Notes”), 0.125% convertible senior notes due December 15, 2024 (the “2024 Notes”) and 1.50% convertible senior notes due November 1, 2022 (the “2022 Notes”) (collective, the “Convertible Senior Notes”). Instead, the Company accounts for the Convertible Senior Notes wholly as debt. Applying the separation models prior to the adoption of ASU 2020-06 to the Convertible Senior Notes involved the recognition of a debt discount, which was amortized to interest expense via the effective interest method. The elimination of the cash conversion model will reduce reported interest expense in periods subsequent to adoption.

Adoption of ASU 2020-06 resulted in an adjustment to the carrying amount of the convertible senior notes, deferred tax liabilities, additional paid-in capital and a cumulative catch-up adjustment to the opening balance of accumulated deficit; however, prior-period information, including basic and diluted loss per share of common stock, has not been adjusted as a result of applying the modified retrospective approach and continue to be reported under the accounting standards in effect for the prior period. The adoption of ASU 2020-06 had no impact on total cash provided from or used in operating, financing, or investing activities in the Company’s condensed consolidated statements of cash flows. For details on the impact of the Company’s adoption of ASU 2020-06, see Note 9.

Recently Issued Accounting Guidance Not Yet Adopted

ASU 2021-08

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires the recognition and measurement of contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers. Considerations to determine the amount of contract assets and contract liabilities to record at the acquisition date include the terms of the acquired contract, such as timing of payment, identification of each performance obligation in the contract and allocation of the contract transaction price to each identified performance obligation on a relative standalone selling price basis as of contract inception. ASU 2021-08 is effective for the Company beginning in the first quarter of 2023. ASU 2021-08 should be applied prospectively for acquisitions occurring on or after the effective date of the amendments. Early adoption of the proposed amendments would be permitted, including adoption in an interim period. The Company is currently assessing the impact this standard will have on the Company’s condensed consolidated financial statements.

Other accounting standard updates effective for interim and annual periods beginning after December 31, 2021 are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

(6) Fair Value Measurements

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of the short maturity of these items.

Certain assets, including long-lived assets, goodwill and intangible assets are also subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review. For the three months ended March 31, 2022 and year ended December 31, 2021, no impairments were identified of those assets requiring measurement at fair value on a non-recurring basis.

The following table summarizes the Company's financial assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy. Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands):

	As of March 31, 2022
	Quoted		Significant
	Prices in		Other		Significant
	Active		Observable		Unobservable
	Markets		Inputs		Inputs		Total Fair

Liabilities:
Contingent consideration	$	—	$	—	$	59	$	59
Total financial liabilities	$	—	$	—	$	59	$	59

The Company classifies and discloses fair value measurements in one of the following three categories of fair value hierarchy:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and liabilities.

Level 2 - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company’s assets that are measured by management at fair value on a recurring basis are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company did not have any transfers into and out of Level 1 or Level 2 during the three months ended March 31, 2022. 

14

The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value and such instruments are classified as Level 1 and are included in cash and cash equivalents on the condensed consolidated balance sheets.

The following tables summarize the changes in Level 3 financial instruments (in thousands):

Fair value at December 31, 2020	$	10,619
Contingent consideration from RedSky acquisition		9,135
Adjustment for one2many acquisition		(690	)
Adjustment for SnapComms acquisition		732
Foreign currency translation		(465	)
Fair value at March 31, 2021	$	19,331

Fair value at December 31, 2021	$	59
Adjustment for Anvil acquisition		(52	)
Foreign currency translation		(1	)
Fair value at March 31, 2022	$	6

The valuation of the contingent consideration was derived using estimates of the probability of achievement within specified time periods based on projections of future revenue metrics per the terms of the applicable agreements. These include estimates of the Company’s assessment of the probability of meeting such results, with the probability-weighted earn-out using a Monte Carlo Simulation Model then discounted to estimate fair value. Fair value is estimated using the probability weighted cash flow estimate closer to the measurement date. The various operating performance measures included in these contingent consideration agreements primarily relate to product revenue. As these are unobservable inputs, the contingent consideration liabilities are included in Level 3 inputs.

During the three months ended March 31, 2022, as a result of assessing the probabilities of payment for the potential contingent consideration for The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited (collectively, “Anvil”) through June 30, 2023, the Company recognized a decrease in the fair value of Anvil’s contingent consideration obligation in the amount of $0.1 million.

The Company estimates the fair value of the convertible senior notes based on market-observable inputs (Level 2). As of March 31, 2022 and December 31, 2021, the fair value of the 2026 Notes was determined to be $326.7 million and $318.3 million, respectively, and the principal amount of the notes was $375.0 million for each period. As of March 31, 2022 and December 31, 2021, the fair value of 2024 Notes was determined to be $407.9 million and $440.6 million, respectively, and the principal amount of the notes was $450.0 million for each period. As of March 31, 2022 and December 31, 2021, the fair value of the 2022 Notes was determined to be $11 thousand and $16 thousand, respectively, and the principal amount of the notes was $8 thousand for each period.

(7) Goodwill and Intangible Assets, Net

The following table displays the changes in the gross carrying amount of goodwill (in thousands):

Balance at December 31, 2021	$	531,163
Acquisition initial value adjustment		(1,602	)
Foreign currency translation		(4,297	)
Balance at March 31, 2022	$	525,264

There were no impairments recorded against goodwill during the three months ended March 31, 2022 and for the year ended December 31, 2021.

Total intangible assets	$	286,928		$	(78,057	)	$	208,871

					As of December 31, 2021
	Gross carrying amount		Weighted average life (years)		Accumulated amortization			Net carrying amount
Amortizable intangible assets:
Developed technology	$	43,178		3.41	$	(16,214	)	$	26,964
Tradenames		28,250		4.13		(12,779	)		15,471
Customer relationships		219,850		8.30		(42,966	)		176,884
Total intangible assets	$	291,278			$	(71,959	)	$	219,319

Amortization expense for intangible assets was $11.6 million and $7.9 million for the three months ended March 31, 2022 and 2021, respectively. The Company recorded amortization expense attributed to developed technology within cost of revenue of $3.2 million and $2.6 million for the three months ended March 31, 2022 and 2021, respectively. During the three months ended March 31, 2022, the Company retired $5.4 million of fully amortized intangible assets.

The expected amortization of the intangible assets, as of March 31, 2022, for each of the next five years and thereafter is as follows (in thousands):

2022 (for the remaining nine months)	$	32,736
2023		39,454
2024		34,005
2025		27,533
2026		21,415
Thereafter		53,728
	$	208,871

(8) Business Combinations

The Company accounted for the following acquisitions using the acquisition method of accounting for business combinations under ASC 805, Business Combinations, which required that the assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the acquisition date. The excess of the purchase price over the net fair value of the assets and liabilities was recorded as goodwill. This goodwill includes the know-how of the assembled workforce, the ability of the workforce to further improve technology and product offerings, customer relationships and the expected cash flows resulting from these efforts. Goodwill may also include expected synergies resulting from the complementary strategic fit these businesses bring to existing operations.

Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives and the expected future cash flows and related discount rates, can materially impact the Company’s results of operations. Significant inputs used for the model included the amount of cash flows, the expected period of the cash flows and the discount rates. Significant estimation was required by management in determining the fair value of the customer relationship intangible assets, deferred revenue and contingent consideration liabilities. The significant estimation is primarily due to the judgmental nature of the inputs to the valuation models used to measure the fair value of these intangible assets, deferred revenue and contingent consideration liabilities, as well as the sensitivity of the respective fair values to the underlying significant assumptions. The Company used the income approach to measure the fair value of these intangible assets, a discounted cash flow approach for deferred revenue and a Monte Carlo simulation model to measure the fair value of the contingent consideration liabilities. The significant assumptions used to estimate the fair value of the intangible assets, deferred revenue and contingent consideration

16

liabilities included forecasted revenues from existing customers, existing customer attrition rates, estimated costs required to fulfill the deferred revenue obligation and forecasted revenues for the contingent consideration earnout period. When estimating the significant assumptions to be used in the valuation the Company includes a consideration of current industry information, market and economic trends, historical results of the acquired business, nature of the performance obligations associated with the deferred revenue and other relevant factors. These significant assumptions are forward-looking and could be affected by future economic and market conditions. The valuation of the contingent consideration was derived using estimates of the probability of achievement within specified time periods based on projections of future revenue metrics per the terms of the applicable agreements. These include estimates of the Company’s assessment of the probability of meeting such results, with the probability-weighted earn-out using a Monte Carlo Simulation Model then discounted to estimate fair value. Fair value is estimated using the probability weighted cash flow estimate closer to the measurement date. The various operating performance measures included in these contingent consideration agreements primarily relate to product revenue. 

The business acquisitions discussed below are included in the Company’s results of operations from their respective dates of acquisition.

2021 Acquisitions

During the year ended December 31, 2021, the Company acquired Red Sky Technologies Inc., xMatters Holdings, Inc. and The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited. These acquisitions were not material and neither the investment in the assets nor the results of operations of these acquisitions were significant to the Company’s consolidated financial position or results of operations, and thus pro forma information is not required to be presented.

Red Sky Technologies Inc.

On January 15, 2021, the Company entered into a Stock Purchase Agreement with Red Sky Technologies Inc. (“RedSky”) pursuant to which the Company purchased all of the issued and outstanding shares of stock of RedSky for a base consideration of $55.4 million, net of cash acquired. The Company paid $32.4 million in cash, net of cash acquired, and issued 162,820 newly issued shares of the Company’s common stock at closing. On the date of this acquisition, the average price of the Company’s common stock on the Nasdaq Global Market was $141.46 per share. In addition to the base purchase price, there was also a potential contingent payment of up to $30 million that was eligible to be earned by the sellers based on certain revenue targets through the contractual measurement period. At the date of the acquisition, the Company preliminarily assessed the probability of RedSky meeting the revenue metrics through the contractual measurement period and recorded a $9.1 million initial fair value of contingent consideration as part of the purchase price allocation. During the year ended December 31, 2021, the Company paid $0.4 million in cash and issued 4,058 shares of the Company’s common stock to settle RedSky’s contingent consideration liability. The Company acquired RedSky for its E911 incident response solutions platform to enhance the Company’s CEM suite of solutions as well as market penetration and customer reach.

xMatters Holdings, Inc.

On April 6, 2021, the Company and xMatters Holdings, Inc. (“xMatters”) signed a definitive agreement pursuant to which the Company agreed to purchase all of the issued and outstanding shares of stock of xMatters. This acquisition closed on May 7, 2021. The Company purchased all of the issued and outstanding shares of stock of xMatters for a base consideration of $242.6 million. The Company paid $178.1 million in cash and issued 555,332 newly issued shares of the Company’s common stock at closing. On the date of this acquisition, the average price of the Company’s common stock on the Nasdaq Global Market was $116.12 per share. The Company acquired xMatters for its service reliability platforms to enhance the Company’s CEM suite of solutions as well as market penetration and customer reach.

17

The following table summarizes the estimated fair value of the assets acquired and the liabilities assumed, which were recorded as of the acquisition date, as well as the aggregate consideration for the acquisition of xMatters made by the Company (in thousands):

	xMatters
Assets acquired
Accounts receivable	$	6,716
Property and equipment		1,458
Trade names		8,200
Acquired technology		8,390
Customer relationships		78,940
Goodwill		170,437
Other assets		5,433
Total assets acquired		279,574
Liabilities assumed
Accounts payable		1,164
Accrued expenses		5,517
Deferred revenue		34,421
Deferred tax liabilities		3,436
Other liabilities		5,056
Net assets acquired	$	229,980
Consideration paid
Cash paid, net of cash acquired	$	165,498
Fair value of common stock issued		64,482
Total	$	229,980

The weighted average useful life of all identified acquired intangible assets is 8.13 years. The average useful lives for acquired technologies, customer relationships and trade names are 3.0 years, 9.0 years and 5.0 years, respectively. Identifiable intangible assets with definite lives are amortized over the period of estimated benefit using the straight-line method. The straight-line method of amortization represents the Company’s best estimate of the period of expected cash flows of the identifiable intangible assets.

The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to the integration of xMatters’ products with the Company's other solutions. The Company believes that the factors listed above in relation to the purchase of xMatters support the amount of goodwill recorded as a result of the purchase price paid for the acquisition, in relation to other acquired tangible and intangible assets. The resulting goodwill from the xMatters acquisition is not deductible for income tax purposes.

For the year ended December 31, 2021, the Company incurred transaction costs of $1.5 million in connection with the xMatters acquisition.

The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited

On November 4, 2021, the Company entered into an agreement with the shareholders of The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited (collectively, “Anvil”) pursuant to which the Company purchased all of the issued and outstanding share capital of Anvil for a base consideration of $161.5 million. The Company paid $70.2 million in cash at closing, acquired net purchase liabilities of $1.6 million and issued $89.7 million consideration loan notes. On November 10, 2021, the Company issued 574,639 newly issued shares of the Company’s common stock to settle consideration loan notes issued on the acquisition date. In addition to the base purchase price, there is also a potential contingent payment of up to $0.8 million that may be paid to the sellers on or before June 30, 2023. At the date of the acquisition, the Company preliminarily assessed the probability of the contingent consideration payment and recorded a $0.1 million preliminary fair value as part of the purchase price allocation. During the three months ended March 31, 2022, the Company recognized a decrease in the fair value of Anvil’s contingent consideration obligation in general and administrative expenses in the condensed consolidated statements of operations in the amount of $0.1 million. The Company acquired Anvil for its travel risk management, operational resiliency and occupational health solutions platforms to enhance the Company’s CEM suite of solutions as well as market penetration and customer reach.

18

As the Company finalizes its estimation of the fair value of the assets acquired and liabilities assumed, additional adjustments may be recorded during the measurement period (a period not to exceed 12 months). The initial accounting is incomplete as of March 31, 2022 for the acquired assets and liabilities as the Company is currently in the process of completing the assessment of valuation inputs and assumptions as well as completing the assessment of the tax attributes of the business combination. The finalization of the acquisition accounting valuation assessment may result in a change in the valuation of the deferred tax assets and liabilities, deferred revenue and intangible assets, along with the opening working capital accounts, which could have a material impact on the Company’s results of operations and financial position.

During the three months ended March 31, 2022, the Company recognized an increase of $2.0 million in customer relationship intangible assets, a $0.5 million increase in deferred tax liabilities and a $1.6 million decrease to goodwill.

The following table summarizes the preliminary estimated fair value of the assets acquired and the liabilities assumed, which were recorded as of the acquisition date, as well as the aggregate consideration for the acquisition of Anvil made by the Company (in thousands):

	Anvil
Assets acquired
Accounts receivable	$	2,361
Property and equipment		204
Trade names		2,600
Acquired technology		3,800
Customer relationships		25,280
Goodwill		127,247
Other assets		5,022
Total assets acquired		166,514
Liabilities assumed
Accounts payable		837
Accrued expenses		934
Deferred revenue		3,365
Deferred tax liabilities		6,119
Other liabilities		1,633
Net assets acquired	$	153,626
Consideration paid
Cash paid, net of cash acquired	$	63,911
Consideration loan notes issued		89,655
Contingent consideration		60
Total	$	153,626

The weighted average useful life of all identified acquired intangible assets is 8.07 years. The average useful lives for acquired technologies, customer relationships and trade names are 4.0 years, 9.0 years and 5.0 years, respectively. Identifiable intangible assets with definite lives are amortized over the period of estimated benefit using the straight-line method. The straight-line method of amortization represents the Company’s best estimate of the period of expected cash flows of the identifiable intangible assets.

The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to the integration of Anvil’s products with the Company's other solutions. The acquisition of Anvil will bring in house the expertise and experience to manage medical and travel-related situations for the Company’s travel risk management offerings to new and existing customers. The Company believes that the factors listed above in relation to the purchase of Anvil support the amount of goodwill recorded as a result of the purchase price paid for the acquisition, in relation to other acquired tangible and intangible assets. The resulting goodwill from the Anvil acquisition is not deductible for income tax purposes.

For the year ended December 31, 2021, the Company incurred transaction costs of $1.4 million in connection with the Anvil acquisition.

(9) Convertible Senior Notes

Adoption of ASU 2020-06

On January 1, 2022, the Company adopted ASU 2020-06 and applied it to its Convertible Senior Notes using the modified retrospective method. Adoption of ASU 2020-06 resulted in an adjustment to convertible senior notes, deferred tax liabilities, additional paid-in capital and accumulated deficit.

0% Convertible Senior Notes Due 2026

In March 2021, the Company issued $375.0 million aggregate principal amount of 0% convertible senior notes due 2026, including $50.0 million aggregate principal amount of 2026 Notes issued upon the initial purchasers’ exercise in full of their option to purchase additional 2026 Notes. The 2026 Notes will mature on March 15, 2026, unless earlier redeemed or repurchased by the Company or converted by the holders pursuant to their terms. The Company will pay special interest, if any, at the Company’s election as the sole remedy relating to the failure to comply with certain reporting obligations and under certain circumstances.

The 2026 Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank National Association, as trustee (the “2026 Notes Indenture”). The 2026 Notes are unsecured and rank: senior in right of payment to the Company’s indebtedness that is expressly subordinated in right of payment to the 2026 Notes; equal in right of payment to the Company’s existing and future indebtedness that is not so subordinated, including its 1.50% convertible senior notes due 2022 (see 1.50% Convertible Senior Notes Due 2022 below) and 0.125% convertible senior notes due 2024 (see 0.125% Convertible Senior Notes Due 2024 below); effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness and other liabilities incurred by the Company’s subsidiaries.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election.

The 2026 Notes have an initial conversion rate of 5.5341 shares of common stock per $1,000 principal amount of 2026 Notes. This represents an initial effective conversion price of approximately $180.70 per share of common stock and approximately 2.1 million shares issuable upon conversion. Throughout the term of the 2026 Notes, the conversion rate may be adjusted upon the occurrence of certain events. Holders of the 2026 Notes will not receive any cash payment representing accrued and unpaid special interest, if any, upon conversion of a 2026 Note, except in limited circumstances. Accrued but unpaid special interest, if any, will be deemed to be paid by cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock paid or delivered, as the case may be, to the holder upon conversion of a 2026 Note.

Holders may convert all or a portion of their 2026 Notes prior to the close of business on the business day immediately preceding December 15, 2025, in multiples of $1,000 principal amount, only under the following circumstances:

• during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

20

• during the five business day period after any ten consecutive trading day period (the “2026 Notes Measurement Period”), in which the “trading price” (as the term is defined in the 2026 Notes Indenture) per $1,000 principal amount of notes for each trading day of such 2026 Notes Measurement Period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

• if the Company calls such notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the notes called (or deemed called) for redemption; or

• upon the occurrence of specified corporate events.

On or after December 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their 2026 Notes at the conversion rate at any time regardless of whether the conditions set forth above have been met.

As of March 31, 2022, the 2026 Notes are not yet convertible. The 2026 Notes are classified as long-term on the condensed consolidated balance sheets as of March 31, 2022 and December 31, 2021 as it is the Company’s intent to settle all of the debt at maturity or to settle in shares if exercised by the debt holder prior to maturity.

The 2026 Notes are not redeemable by the Company prior to March 20, 2024. The Company may redeem for cash all or any portion of the 2026 Notes, at its option, on or after March 20, 2024 if the last reported sale price of the Company's common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date.

The 2026 Notes consist of the following (in thousands):

	As of			As of

⁽¹⁾ Upon adoption of ASU 2020-06, the Company no longer separately presents the embedded conversion feature in equity. As of December 31, 2021, the equity component was recorded in the consolidated balance sheet within additional paid-in capital, net of $3.0 million transaction costs in equity and net of $3.4 million for taxes.

The following table sets forth total interest expense recognized related to the 2026 Notes (in thousands):

	Three Months Ended March 31,

Effective interest rates were 0.6% and 7.3% for the three months ended March 31, 2022 and 2021, respectively.

The fair value of the 2026 Notes, which was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, quoted price of the 2026 Notes in an over-the-counter market (Level 2), and carrying value of debt instruments (prior to the adoption of ASU 2020-06, carrying value excluded the equity component of the Company’s 2026 Notes classified in equity) were as follows (in thousands):

In connection with the issuance of the 2026 Notes, the Company entered into capped call transactions with certain counterparties affiliated with the initial purchasers and other financial institutions. The capped call transactions are expected generally to reduce potential dilution to the Company’s common stock upon any conversion of the 2026 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2026 Notes, as the case may be, with such reduction and/or offset subject to a cap. Under the capped call transactions, the Company purchased capped call options that in the aggregate relate to the total number of shares of the Company’s common stock underlying the 2026 Notes, with an initial strike price of approximately $180.70 per share, which corresponds to the initial conversion price of the 2026 Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the 2026 Notes, and with a cap price of approximately $258.14. The cost of the purchased capped calls of $35.1 million was recorded to shareholders’ equity and will not be re-measured.

Based on the closing price of the Company’s common stock of $43.64 on March 31, 2022, the if-converted value of the 2026 Notes was less than their respective principal amounts.

0.125% Convertible Senior Notes Due 2024

In December 2019, the Company issued $450.0 million aggregate principal amount of 0.125% convertible senior notes due 2024, including $75.0 million aggregate principal amount of 2024 Notes issued upon the initial purchasers’ exercise in full of their option to purchase additional 2024 Notes. The 2024 Notes will mature on December 15, 2024, unless earlier redeemed or repurchased by the Company or converted by the holders pursuant to their terms. Interest is payable semiannually in arrears on June 15 and December 15 of each year, commencing on June 15, 2020.

The 2024 Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank National Association, as trustee (the “2024 Notes Indenture”). The 2024 Notes are unsecured and rank: senior in right of payment to the Company’s indebtedness that is expressly subordinated in right of payment to the 2024 Notes; equal in right of payment to the Company’s existing and future indebtedness that is not so subordinated, including its 2026 Notes and 2022 Notes; effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness and other liabilities incurred by the Company’s subsidiaries.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election.

The 2024 Notes have an initial conversion rate of 8.8999 shares of common stock per $1,000 principal amount of 2024 Notes. This represents an initial effective conversion price of approximately $112.36 per share of common stock and approximately 4.0 million shares issuable upon conversion. Throughout the term of the 2024 Notes, the conversion rate may be adjusted upon the occurrence of certain events. Holders of the 2024 Notes will not receive any cash payment representing accrued and unpaid interest, if any, upon conversion of a 2024 Note, except in limited circumstances.

Holders may convert all or a portion of their 2024 Notes prior to the close of business on the business day immediately preceding June 15, 2024, in multiples of $1,000 principal amount, only under the following circumstances:

• during any calendar quarter commencing after the calendar quarter ending on March 31, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

(10) Stockholders’ Equity

Preferred Stock

As of March 31, 2022, the Company had authorized 10,000,000 shares of preferred stock, par value $0.001, of which no shares were outstanding.

Common Stock

As of March 31, 2022, the Company had authorized 100,000,000 shares of common stock, par value $0.001. Holders of common stock are entitled to one vote per share. At March 31, 2022 and December 31, 2021, there were 39,504,354 and 39,389,733 shares of common stock issued and outstanding, respectively.

(11) Stock Plans and Stock-Based Compensation

The Company’s 2016 Equity Incentive Plan (the “2016 Plan”) became effective on September 15, 2016. The 2016 Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and performance share awards to employees, directors and consultants of the Company. The number of shares of common stock reserved for issuance under the 2016 Plan will automatically increase on January 1 of each year by 3% of the number of shares of the Company’s capital stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s board of directors.

2016 Employee Stock Purchase Plan

The Company’s Employee Stock Purchase Plan (the “2016 ESPP”) became effective on September 15, 2016. The number of shares reserved for issuance under the 2016 ESPP will automatically increase on January 1 of each year by the lesser of 200,000 shares of the Company’s common stock, 1% of the number of shares of the Company’s common stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s board of directors.

The 2016 ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of up to 15% through payroll deductions of their eligible compensation, subject to any plan limitations. The 2016 ESPP provides for separate six-month offering periods beginning each March and September of each fiscal year.

25

On each purchase date, eligible employees will purchase the Company’s stock at a price per share equal to 85% of the lesser of (i) the fair market value of the Company’s common stock on the offering date or (ii) the fair market value of the Company’s common stock on the purchase date.

For the three months ended March 31, 2022 and 2021, 58,747 and 23,499 shares of common stock were purchased under the 2016 ESPP, respectively. The Company recorded stock-based compensation expense of $0.4 million and $0.5 million for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, unrecognized compensation cost related to the 2016 ESPP was $0.6 million which will be amortized over a weighted-average period of 0.42 years. 

The fair value of shares issuable under the 2016 ESPP is determined using the Black-Scholes option pricing model with the following weighted average assumptions: 

	Three Months Ended March 31,
	2022		2021
Employee Stock Purchase Plan:
Expected term (in years) (1)		0.50		0.50
Expected volatility (2)	65%		60%
Risk-free interest rate (3)	0.86%		0.06%
Dividend rate (4)	0%		0%

⁽¹⁾ The expected term represents the contractual term of the 2016 ESPP;

⁽²⁾ The expected volatility of the Company’s common stock on the date of grant is based on the weighted average of the Company’s historical volatility as a public company, the implied volatility of publicly-traded options on the Company’s common stock and the volatilities of publicly traded peer companies that are reasonably comparable to the Company’s own operations;

⁽³⁾ The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the grant; and

⁽⁴⁾ The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on the Company’s common stock.

Stock Options

Stock option awards are granted with an exercise price equal to the fair market value of the Company’s common stock at the date of grant based on the closing market price of its common stock as reported on The Nasdaq Global Market. The option awards generally vest over four years and are exercisable any time after vesting. The stock options expire ten years after the date of grant.

There were no stock options granted during the three months ended March 31, 2022 and 2021. The Company recorded stock-based compensation expense of $0.1 million and $0.4 million for the three months ended March 31, 2022 and 2021, respectively, attributed to stock options.    

The total intrinsic value of options exercised for the three months ended March 31, 2022 and 2021 was less than $0.1 million and $6.3 million, respectively. This intrinsic value represents the difference between the fair market value of the Company’s common stock on the date of exercise and the exercise price of each option. Based on the fair market value of the Company’s common stock at March 31, 2022 and 2021, the total intrinsic value of all outstanding options was $3.1 million and $21.5 million, respectively.

Total unrecognized compensation cost related to nonvested stock options was less than $0.1 million as of March 31, 2022 and is expected to be recognized over a weighted average period of 0.07 years. The amount of cash received from the exercise of stock options during the three months ended March 31, 2022 and 2021 was less than $0.1 million and $1.6 million, respectively.

The following table summarizes the Company’s stock option activity:

	Stock options outstanding			Weighted average exercise price
Outstanding at December 31, 2021		157,740		$	23.83
Exercised		(725	)		24.58

Restricted Stock Units

During the three months ended March 31, 2022, the Company granted 1,268,273 restricted stock units (“RSUs”) to members of its senior management and certain other employees pursuant to the 2016 Plan. There were 62,976 RSUs that vested during the three months ended March 31, 2022. The Company accounts for RSUs issued to employees at fair value, based on the market price of the Company’s common stock on the date of grant. The weighted-average grant date fair values of RSUs granted during the three months ended March 31, 2022 and 2021 were $39.78 and $132.34, respectively. The fair values of RSUs that vested during the three months ended March 31, 2022 and 2021, were $5.4 million and $4.0 million, respectively. During the three months ended March 31, 2022 and 2021, the Company recorded $7.0 million and $5.9 million, respectively, of stock-based compensation related to the RSUs.

As of March 31, 2022, there was $87.5 million of unrecognized compensation expense related to unvested RSUs which is expected to be recognized over a weighted-average period of approximately 2.55 years. For RSUs subject to graded vesting, the Company recognizes compensation cost on a straight-line basis over the service period for the entire award.

Performance-Based Restricted Stock Units

On February 9, 2022, the Compensation Committee of the Company’s Board of Directors approved a modification to the performance thresholds of the Company’s performance-based restricted stock unit (“PSU”) awards which affected 785 grantees and excluded our Named Executive Officers for 2021. The modified PSUs vest based on the Company achieving certain revenue growth thresholds which range from 1% to 40% compounded annual growth over the measurement period. For the portion of the PSUs where the expectation of the achievement of performance conditions changed from improbable prior to the modification to probable post-modification, the Company accounted for this change as a Type III modification under ASC 718, Compensation—Stock Compensation. The modification date fair value for the PSUs was $55.31. As of the modification date, total incremental stock-based compensation expense was $17.5 million which will be recognized over the remaining service periods of the PSU less subsequent forfeitures.

During the three months ended March 31, 2022, the Company granted 379,229 PSUs to members of its management pursuant to the 2016 Plan. There were 5,584 PSUs that vested during the three months ended March 31, 2022. The PSUs, other than those modified on February 9, 2022 as described above, generally vest based on the Company achieving certain revenue growth thresholds which ranged from 20% to 40% compounded annual growth for grants through 2020 and 15% to 35% compounded annual growth for grants starting in 2021 over a measurement period of two years for the first 50% of PSUs and three years for the remaining PSUs. The vesting of the PSUs is subject to the employee’s continued employment with the Company through the date of achievement. During the three months ended March 31, 2022, the share price of the Company’s common stock on the date of issuance of the PSUs ranged from $36.59 to $55.31 per share. The fair value is based on the value of the Company’s common stock at the date of issuance and the probability of achieving the performance metric. Compensation cost is adjusted in future periods for subsequent changes in the expected outcome of the performance related conditions. The weighted-average grant date fair values of PSUs granted during the three months ended March 31, 2022 and 2021 were $38.79 and $133.06, respectively.

27

During the three months ended March 31, 2022 and 2021, the Company recognized a credit of $(1.4 million) and $5.9 million, respectively, of stock compensation expense in connection with the PSU awards. During the three months ended March 31, 2022, prior to the PSU modification, as a result of forecasted decreases in the compounded annual growth rate, the Company reduced the expected achievement of performance metrics and recognized a reduction in stock-based compensation expense. This reduction was partially offset by the incremental compensation expense recognized for the modified PSUs. As of March 31, 2022, there was $28.7 million of unrecognized compensation expense related to unvested PSUs which is expected to be recognized over a weighted-average period of approximately 2.00 years. Compensation cost is recognized under the accelerated method and is adjusted in future periods for subsequent changes in the expected outcome of the performance related conditions.

The following table summarizes the Company’s RSU and PSU activity:

	Number of Shares
Outstanding at December 31, 2021		1,579,738
Granted		1,647,502
Vested		(68,560	)
Forfeited		(307,617	)
Outstanding at March 31, 2022		2,851,063

Market-Based Grants

During the three months ended March 31, 2022, the Company issued market-based grants, which are payable in cash to partially settle a vendor contract. The grants vest contingent upon the achievement of pre-determined market and service conditions. Cash payment at settlement will range from zero to approximately $1.3 million based on the Company’s total stockholder return (“TSR”) relative to the performance of peer companies through September 2023. The market-based grants are classified as a liability on the Company’s balance sheet and will be remeasured at each reporting period until settlement. The grant date fair value of the market-based grants was $0.4 million. The key estimates used in the Monte-Carlo simulation were a risk-free rate of 1.97%, dividend yield of zero, expected term of 1.50 years and volatility of 58%. During the three months ended March 31, 2022, the Company recognized an immaterial amount of stock compensation expense in connection with these awards. As of March 31, 2022, there was $0.4 million of unrecognized compensation expense related to the market-based grants which is expected to be recognized over approximately 0.22 years.

Stock-Based Compensation Expense

The Company recorded the total stock-based compensation expense as follows (in thousands):

	Three Months Ended March 31,
	2022		2021
Cost of revenue	$	817	$	999
Sales and marketing		1,295		3,742
Research and development		1,723		2,028
General and administrative		2,249		5,916
Total	$	6,084	$	12,685

Stock-based compensation expense is recognized over the award’s expected vesting schedule, which is reduced for forfeitures.

(12) Basic and Diluted Net Loss per Share

Basic net loss per common share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive shares of common stock. Basic and diluted net loss per share of common stock were the same for all periods presented as the impact of all potentially dilutive securities outstanding was anti-dilutive. The Company uses the if converted method for convertible senior notes for calculating any potential dilutive effect on diluted loss per share.

28

The following common equivalent shares were excluded from the diluted net loss per share calculation because their inclusion would have been anti-dilutive:

	As of March 31,
	2022		2021
Convertible senior notes		6,080,480		6,125,864
Stock-based compensation grants		3,007,953		1,602,837
Total		9,088,433		7,728,701

In connection with the issuance of the 2026 Notes in March 2021, the Company paid $35.1 million to enter into capped call option agreements to reduce the potential dilution to holders of the Company’s common stock upon conversion of the 2026 Notes. In connection with the issuance of the 2024 Notes in December 2019, the Company paid $44.9 million to enter into capped call option agreements to reduce the potential dilution to holders of the Company’s common stock upon conversion of the 2024 Notes. In connection with the issuance of the 2022 Notes in November 2017, the Company paid $12.9 million to enter into capped call option agreements to reduce the potential dilution to holders of the Company’s common stock upon conversion of the 2022 Notes. In March 2021 and December 2019, the Company partially terminated capped call options related to the 2022 Notes and received $10.6 million and $5.8 million, respectively. In March 2021, the Company also modified a capped call agreement entered into in connection with the 2022 Notes and recognized modification expense of $0.2 million in loss on extinguishment of convertible notes and capped call modification on the condensed consolidated statement of operations. The capped call option agreements are excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive.

Reserve for Unissued Shares of Common Stock

The Company is required to reserve and keep available out of its authorized but unissued shares of common stock such number of shares sufficient for the exercise of all shares granted and available for grant under the Company’s 2008 Equity Incentive Plan, 2016 Plan and 2016 ESPP. The amount of such shares of the Company’s common stock reserved for these purposes at March 31, 2022 was 6.7 million shares. Additionally, the Company is required to reserve and keep available out of its authorized but unissued shares of common stock shares that become issuable pursuant to the terms of the 2026 Notes, 2024 Notes and 2022 Notes.

(13) Income Taxes

The Company is subject to income tax in the United States as well as other tax jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income tax. The Company does not provide for U.S. deferred income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are reinvested indefinitely.

The Company’s tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual tax rate changes, the Company makes a cumulative adjustment in that quarter. The Company’s quarterly tax provision, and its quarterly estimate of its annual effective tax rate, are subject to significant volatility due to several factors, including the Company’s ability to accurately predict its pre-tax income and loss in multiple jurisdictions.

For the three months ended March 31, 2022 and 2021, the Company recorded a benefit from income taxes of $1.1 million and a benefit from income taxes of $5.8 million, respectively, resulting in an effective tax rate of 5.35% and an effective rate of 21.06%, respectively. The benefit of $1.1 million generated in the three months ended March 31, 2022, was primarily generated by losses in foreign jurisdiction which are expected to be realized in the current or future years. For the three months ended March 31, 2021, there were deferred tax liabilities recognized in connection with the preliminary purchase accounting for the Company’s completed acquisitions. Certain of such deferred tax liabilities will be a source of future taxable income to realize a portion of Company’s deferred tax assets, which resulted in a discrete tax benefit of approximately $5.8 million related to U.S. acquired entities being recognized during the three months ended March 31, 2021.

As of March 31, 2022, the Company had gross tax-effected unrecognized tax provision of $1.8 million which, if recognized, would favorably impact the effective tax rate. The Company’s existing tax positions will continue to generate an increase in unrecognized tax benefits in subsequent periods. The Company’s policy is to record interest and penalties related to unrecognized tax benefits as a component of income tax expense. During the three months ended March 31, 2022 and 2021, the amounts recorded related to the accrual of interest and penalties were immaterial in each period.  

29

(14) Segment information

The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assess the Company’s financial and operational performance. Patrick Brickley, Executive Vice President, Chief Financial Officer and Treasurer and Interim Co-Chief Executive Officer, and Vernon Irvin, Executive Vice President, Chief Revenue Officer and Interim Co-Chief Executive Officer are interim CODMs of the Company. While the Company has applications that address multiple use cases, the Company’s applications generally operate on and leverage a single technology platform and are deployed and sold in an identical way. In addition, the Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. As a result, the Company has determined that the Company’s business operates in a single operating segment. Since the Company operates as one operating segment, all required financial segment information can be found in the consolidated financial statements.

(15) Revenue Recognition

The following table disaggregates the Company’s revenue by geography which provides information as to the major source of revenue (in thousands):

	Three Months Ended March 31,
Primary Geographic Markets	2022		2021
United States	$	72,069	$	57,465
International		28,306		24,745
Total	$	100,375	$	82,210

The following table presents the Company’s revenues disaggregated by revenue source (in thousands):

	Three Months Ended March 31,
	2022		2021
Subscription services	$	91,855	$	70,432
Professional services		6,541		5,940
Software licenses and other		1,979		5,838
Total	$	100,375	$	82,210

Contract Assets

The Company does not have material amounts of contract assets since revenue is recognized as control of goods is transferred or as services are performed. There are a small number of professional services that may occur over a period of time, but that period of time is generally very short in duration. Any contract assets that may arise are recorded in other assets in the Company’s condensed consolidated balance sheet net of an allowance for credit losses.

Contract Liabilities

The Company’s contract liabilities consist of advance payments and deferred revenue. The Company’s contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. The Company classifies advance payments and deferred revenue as current or noncurrent based on the timing of when it expects to recognize revenue. Generally, all contract liabilities are expected to be recognized within one year and are included in deferred revenue in the Company’s condensed consolidated balance sheet. The noncurrent portion of deferred revenue is included and separately disclosed in the Company’s condensed consolidated balance sheet.

Deferred Costs

Current deferred costs, which primarily consist of deferred sales commissions, were $16.1 million and $15.8 million as of March 31, 2022 and December 31, 2021, respectively. Noncurrent deferred costs, which primarily consist of deferred sales commissions, were $18.9 million and $17.0 million as of March 31, 2022 and December 31, 2021, respectively. During the three months ended March 31, 2022 and 2021, amortization expense for the deferred costs was $4.0 million and $3.7 million, respectively. There was no impairment loss in relation to the costs capitalized for the three months ended March 31, 2022 and the year ended December 31, 2021, respectively.

30

Deferred Revenue

During the three months ended March 31, 2022 and 2021, $83.7 million and $59.7 million, respectively, of subscription services, license and other revenue was recognized and was included in the deferred revenue balances at the beginning of the respective period.

During the three months ended March 31, 2022 and 2021, $4.0 million and $4.5 million, respectively, of professional services revenue was recognized and was included in the deferred revenue balances at the beginning of the respective period.

As of March 31, 2022, approximately $450.3 million of revenue is expected to be recognized from remaining performance obligations for subscription and other contracts. The Company expects to recognize revenue on approximately $284.6 million of these remaining performance obligations over the next 12 months, with the balance recognized thereafter.      

As of March 31, 2022, approximately $19.1 million of revenue is expected to be recognized from remaining performance obligations for professional services contracts. The Company expects to recognize revenue on approximately $16.5 million of these remaining performance obligations over the next 12 months, with the balance recognized thereafter.

(16) Leases

The Company’s leases relate primarily to office facilities that expire on various dates from 2022 through 2029. The terms of the Company's non-cancelable operating lease arrangements typically contain fixed lease payment which increases over the term of the lease at fixed rates, rent holidays and provide for additional renewal periods. Lease expense is recognized over the term of the lease on a straight-line basis. All of the Company’s leases are classified as operating leases. The Company has determined that periods covered by options to extend the Company’s leases are excluded from the lease term as the Company is not reasonably certain the Company will exercise such options.

The Company records its right-of-use (“ROU”) asset within other assets (long term) and its operating lease liabilities within other current and long-term liabilities.

Additional information related to the Company’s leases is as follows (in thousands, except lease term and discount rate):

(17) Commitments and Contingencies

Litigation

In April 2022, a putative class action lawsuit was filed in the United States District Court for the Central District of California against the Company, Jaime Ellertson, Patrick Brickley, and David Meredith (the Company’s former Chief Executive Officer) by Sylebra Capital Partners Master Fund Ltd, Sylebra Capital Parc Master Fund, and Sylebra Capital Menlo Master Fund. The lawsuit alleges violations of the federal securities laws by the Company and certain of its officers and directors arising out of purported misrepresentations in the information the Company provided to investors regarding the Company’s organic and inorganic revenue growth, the status of integrating acquisitions, and the impact of COVID-19 on the Company’s business, which allegedly artificially inflated the price of the Company’s stock during the period November 4, 2019 to February 24, 2022. The Company is not able to estimate the amount of the loss allegedly suffered by members of the putative class or the amount of legal costs and internal efforts associated with defending the Company and the Company’s officers and directors. The Company believes that the allegations and claims made in this lawsuit are wholly without merit and intends to defend the action vigorously. Even if the Company were to prevail, this litigation could continue to be costly and time-consuming and divert the attention of the Company’s management and key personnel from the Company’s business operations. During the course of the litigation, the Company anticipates announcements of the results of hearings and motions, and other interim developments related to the litigation. If securities analysts or investors regard these announcements as negative, the market price of the Company’s common stock may decline. If the Company is unsuccessful in defending itself in this litigation, this lawsuit could materially and adversely affect the Company’s business, financial condition, results of operations and cash flows.

From time to time the Company may become involved in other legal proceedings or be subject to claims arising in the ordinary course of business. Although the results of ordinary course litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business, financial condition, results of operations or cash flows. Regardless of the outcome, litigation can have an adverse impact because of defense and settlement costs, diversion of management resources and other factors.

32

Employee Contracts

The Company has entered into employment contracts with certain of the Company’s executive officers which provide for at-will employment. However, under the provisions of the contracts, the Company would incur severance obligations of up to twelve months of the executive’s annual base salary for certain events, such as involuntary terminations.

(18) Subsequent Event

2022 Strategic Realignment

On May 3, 2022, the Board of Directors of the Company approved a program (the “2022 Strategic Realignment”) to strategically realign the Company’s resources in order to accelerate and grow the Company’s investments in the Company’s largest growth opportunities while streamlining the Company’s operations. This program is in support of the 2022 strategic initiatives to simplify the Company’s business and accelerate the integration of recent acquisitions, and will help to drive the financial outcomes of sustainable growth and improved profitability and cash flow. The 2022 Strategic Realignment program includes a targeted realignment and reduction of headcount, facilities and other third-party spend.

The 2022 Strategic Realignment charges will result in future cash expenditures of approximately $13 million to $21 million the majority of which the Company expects to be paid during fiscal 2022 with the remainder paid through fiscal 2028. The 2022 Strategic Realignment is expected to be substantially completed by the first half of fiscal 2023. The Company expects to record approximately $5 million to $9 million in restructuring charges associated with the 2022 Strategic Realignment, including employee termination benefits, costs to consolidate facilities and other costs. The Company also expects to incur $8 million to $12 million in business transformation costs associated with the 2022 Strategic Realignment, including employee retention costs, professional fees and investments in automation and technology.

Overview

Everbridge is a global software company that provides enterprise software applications that automate and accelerate organizations’ operational response to critical events in order to keep people safe and organizations running. During public safety threats including severe weather conditions, active shooter situations, terrorist attacks or a pandemic, as well as critical business events such as IT outages, cyber-attacks, product recalls or supply-chain interruptions, global customers rely on our Critical Event Management platform to quickly and reliably aggregate and assess threat data, locate people at risk and responders able to assist, automate the execution of pre-defined communications processes and track progress on executing response plans. Our customers use our platform to identify and assess hundreds of different types of threats to their organizations, people, assets or brand. Our solutions enable organizations to deliver intelligent, contextual messages to, and receive verification of delivery from, hundreds of millions of recipients, across multiple communications modalities such as voice, SMS and e-mail, in over 200 countries and territories, in several languages and dialects – all simultaneously. Our Critical Event Management platform is comprised of a comprehensive set of software applications packaged for organizations to address five core use cases, safeguarding: Business Operations, People Resilience, Digital Operations, Smart Security, and Public Safety. Everbridge’s individual products, addressing the full spectrum of tasks an organization requires to manage a critical event, include Mass Notification, Safety Connection, IT Alerting, Visual Command Center, Public Warning, Community Engagement, Risk Center, Crisis Management, CareConverge, Control Center, 911 Connect, Travel Risk Management, SnapComms and E911. We believe that our broad suite of integrated, enterprise applications delivered via a single global platform is a significant competitive advantage in the market for Critical Event Management solutions, which we refer to generally as CEM.

Our customer base has grown from 867 customers at the end of 2011 to more than 6,224 customers as of March 31, 2022. We provide our applications to customers of varying sizes, including enterprises, small businesses, non-profit organizations, educational institutions and governmental agencies. Our customers span a wide variety of industries including technology, energy, financial services, healthcare and life sciences, manufacturing, media and entertainment, retail, higher education and professional services.

We sell all of our critical event management applications on a subscription basis. We generally enter into contracts that range from one to three years in length, with an average contract duration of 1.8 years as of March 31, 2022, and generally bill and collect payment annually in advance. We derive most of our revenue from subscriptions to applications. On average, 95% of the revenue that we recognized in each of the eight most recently completed quarters was generated from contracts entered into in prior quarters or renewals of those contracts; the balance of the revenue that we recognized in each such quarter was generated from contracts entered into with new customers or new contracts, other than renewals, entered into with existing customers in such quarter. We derived approximately 42% of our revenue in 2021 from sales of our Mass Notification application. Our pricing model is based on the number of applications subscribed to and, per application, the number of people, locations and things connected to our platform as well as the volume of communications. We also offer premium services including data feeds for social media, threat intelligence and weather. We generate additional revenue by expanding the number of applications that our customers subscribe to and the number of contacts and devices connected to our platform.

34

We generated revenue of $100.4 million and $82.2 million for the three months ended March 31, 2022 and 2021, respectively, representing a period-over-period increase of 22%. We had net losses of $19.1 million and $21.8 million for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022 and 2021, 21% and 23% of our customers, respectively, were located outside of the United States. These customers generated 28% and 30% of our total revenue for the three months ended March 31, 2022 and 2021, respectively.

We have focused on rapidly growing our business and believe that the future growth of our business is dependent on many factors, including our ability to increase the functionality of our platform and applications, expand our customer base, accelerate adoption of our applications beyond Mass Notification within our existing customer base and expand our international presence. Our future growth will also depend on the growth in the market for critical event management solutions and our ability to effectively compete. In order to further penetrate the market for critical event management solutions and capitalize on what we believe to be a significant opportunity, we intend to continue to invest in research and development, build-out our data center infrastructure and services capabilities and hire additional sales representatives, both domestically and internationally, to drive sales to new customers and incremental sales of new applications to existing customers. Nevertheless, we expect to continue to incur losses in the near term and, if we are unable to achieve our growth objectives, we may not be able to achieve profitability.

Recent Developments

2022 Strategic Realignment

On May 3, 2022, our Board of Directors approved a program (the “2022 Strategic Realignment”) to strategically realign our resources in order to accelerate and grow our investments in our largest growth opportunities while streamlining our operations. This program is in support of the 2022 strategic initiatives to simplify our business and accelerate the integration of recent acquisitions, and will help to drive the financial outcomes of sustainable growth and improved profitability and cash flow. The 2022 Strategic Realignment program includes a targeted realignment and reduction of headcount, facilities and other third-party spend.

On February 9, 2022, the Compensation Committee of our Board of Directors approved a modification to the performance thresholds of our performance-based restricted stock unit (“PSU”) awards which affected 785 grantees and excluded our Named Executive Officers for 2021. The modified PSUs vest based on certain revenue growth thresholds which range from 1% to 40% compounded annual growth over the measurement period. The modification date fair value for the PSUs was $55.31. Incremental stock-based compensation expense of $17.5 million will be recognized over the remaining service periods of the PSUs.

Impacts of COVID-19 to Our Business

During the three months ended March 31, 2022, financial results and operations for our Americas and international geographies were not significantly impacted by the COVID-19 pandemic. We have taken, and continue to take, a variety of measures to ensure the availability and functioning of our critical infrastructure, to promote the safety and security of our employees and to support the communities in which we operate. These measures include requiring remote working arrangements for employees where practicable, among other modifications. We are following evolving public and private sector policies and initiatives to reduce the transmission of COVID-19, such as the imposition of travel restrictions, the promotion of social distancing and the adoption of work-from-home arrangements. All of these policies and initiatives have been and may continue to impact our operations. We will continue to actively monitor the situation and may take further actions that alter our business operations as may be required or that we determine are in the best interests of our employees, customers, suppliers and stockholders. Due to the evolving nature of the situation, we are not able at this time to estimate the future impact of the pandemic on our financial results and operations, but the impact could be material during any future period affected either directly or indirectly by this pandemic. Due to our primarily subscription-based business model, the effect of the coronavirus may not be fully reflected in our results of operations until future periods, if at all. See Part I-Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 25, 2022, for information on risks associated with pandemics in general and COVID-19 specifically. The extent of the future impact of COVID-19 on our operational and financial performance will depend on certain developments, including new information which may emerge concerning the duration and severity of the outbreak, impact of vaccinations and virus variants, international actions taken or which may be taken in the future to contain and treat it, impact on our customers and our sales cycles, and impact on our employees, all of which are highly uncertain and cannot be predicted.

Presentation of Financial Statements

Our consolidated financial statements include the accounts of our wholly-owned subsidiaries. Business acquisitions are included in our consolidated financial statements from the date of the acquisition. Our purchase accounting resulted in all assets and liabilities of acquired businesses being recorded at their estimated fair values on the acquisition dates. All intercompany balances and transactions have been eliminated in consolidation.

35

We report our financial results as one operating segment. Our operating results are regularly reviewed on a consolidated basis by our chief executive officer, who is our chief operating decision maker (“CODM”), principally to make strategic decisions regarding how we allocate our resources and to assess our consolidated operating performance. Patrick Brickley, Executive Vice President, Chief Financial Officer and Treasurer and Interim Co-Chief Executive Officer, and Vernon Irvin, Executive Vice President, Chief Revenue Officer and Interim Co-Chief Executive Officer are our interim CODMs.

Adoption of Accounting Standards Update 2020-06

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. We adopted the standard on January 1, 2022 using the modified retrospective approach. Upon adoption of ASU 2020-06, we no longer separately present in equity the embedded conversion feature of the 0% convertible senior notes due March 15, 2026 (the “2026 Notes”), 0.125% convertible senior notes due December 15, 2024 (the “2024 Notes”) and 1.50% convertible senior notes due November 1, 2022 (the “2022 Notes”) (collective, the “Convertible Senior Notes”). Instead, we account for the Convertible Senior Notes wholly as debt. Applying the separation models prior to the adoption of ASU 2020-06 to the Convertible Senior Notes involved the recognition of a debt discount, which was amortized to interest expense via the effective interest method. The elimination of the cash conversion model will reduce reported interest expense in periods subsequent to adoption.

During the three months ended March 31, 2022, we recognized amortization of deferred costs in interest expense based on ASU 2020-06. As we adopted the standard using the modified retrospective approach, periods prior to our adoption have not been recast and are not directly comparable. See Notes 2 and 9 in the notes to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for additional discussion of the impact of the adoption of ASU 2020-06.

Components of Results of Operations

Revenue

We derive most of our revenue from the sale of subscriptions to our critical event management and enterprise safety applications.

We generally bill and collect payment for our subscriptions annually in advance. All revenue billed in advance of services being delivered is recorded in deferred revenue. The initial subscription period typically ranges from one to three years. We offer varying levels of customer support based on customer needs and the complexity of their businesses, including the level of usage by a customer in terms of minutes or the amount of data used to transmit the notifications. Our pricing model is based on the number of applications subscribed to and, per application, the number of people, locations and things connected to our platform as well as the volume of communications. We also offer premium services including data feeds for social media, threat intelligence and weather. We generate additional revenue by expanding the number of premium features and applications that our customers subscribe to and the number of contacts connected to our platform. Our revenue growth in the near-term may be adversely affected by our ability to integrate our recent acquisitions, drive new client adoption and sales of our full suite of solutions.

We also sell professional services, which primarily consist of fees for deployment and optimization services as well as training. In addition, we also sell our software and related post contract support for on premises usage.

Cost of Revenue

Cost of revenue includes expenses related to the fulfillment of our subscription services, consisting primarily of employee-related expenses for data center operations and customer support, including salaries, bonuses, benefits and stock-based compensation expense. Cost of revenue also includes hosting costs, messaging costs and depreciation and amortization. As we add data center capacity and support personnel in advance of anticipated growth, our cost of revenue will increase and, if anticipated revenue growth does not occur, our gross profit will be adversely affected. We expect expenses to increase during fiscal year 2022 as a result of the 2022 Strategic Realignment. After the 2022 Strategic Realignment is implemented, we expect a reduction in operational costs.  

Operating Expenses

Operating expenses consist of sales and marketing, research and development and general and administrative expenses. Salaries, bonuses, stock-based compensation expense and other personnel costs are the most significant components of each of these expense categories. We include stock-based compensation expense incurred in connection with the grant of stock options, restricted stock units, performance-based restricted stock units, market-based grants and our employee stock purchase plan within the applicable operating expense category based on the equity award recipient’s functional area.

36

Sales and Marketing

Sales and marketing expense primarily consists of employee-related expenses for sales, marketing and public relations employees, including salaries, bonuses, commissions, benefits and stock-based compensation expense. Sales and marketing expense also includes trade show, market research, advertising and other related external marketing expense as well as office and software related costs to support sales. We defer certain sales commissions related to acquiring new customers or services and amortize these expenses ratably over the period of benefit that we have determined to be four years. Sales commissions attributable to professional services are expensed within twelve months of selling the service to the customer. We plan to continue to expand our sales and marketing functions to grow our customer base and increase sales to existing customers. This growth will include adding sales personnel and expanding our marketing activities to continue to generate additional leads and build brand awareness. We expect expenses to increase during fiscal year 2022 as a result of the 2022 Strategic Realignment. After the 2022 Strategic Realignment is implemented, we expect a reduction in operational costs.

Research and Development

Research and development expense primarily consists of employee-related expenses for research and development staff, including salaries, bonuses, benefits and stock-based compensation expense. Research and development expense also includes the cost of certain third-party services, office related costs to support research and development activities, software subscriptions and hosting costs. We capitalize certain software development costs that are attributable to developing new applications and adding incremental functionality to our platform and amortize these costs over the estimated life of the new application or incremental functionality, which is generally three years. We focus our research and development efforts on improving our applications, developing new applications and delivering new functionality. We expect expenses to increase during fiscal year 2022 as a result of the 2022 Strategic Realignment. After the 2022 Strategic Realignment is implemented, we expect a reduction in operational costs.

General and Administrative

General and administrative expense primarily consists of employee-related expenses for administrative, legal, finance and human resource personnel, including salaries, bonuses, benefits and stock-based compensation expense. General and administrative expense also includes professional fees, insurance premiums, corporate expenses, transaction-related costs, office-related expenses, facility costs, depreciation and amortization and software license costs. In the near term, we expect our general and administrative expense to increase on an absolute dollar basis as we continue to incur the costs associated with being a publicly traded company. We expect expenses to increase during fiscal year 2022 as a result of the 2022 Strategic Realignment. After the 2022 Strategic Realignment is implemented, we expect a reduction in operational costs.

Interest and Investment Income

Interest income consists of interest earned on our cash balances held at financial institutions. Investment income consist of interest earned on our short-term investments which consist of U.S. treasuries, U.S. government agency obligations and money market funds.

Interest Expense

Interest expense consists of interest on our outstanding debt obligations including amortization of debt discounts and offering costs.

Loss on Extinguishment of Convertible Notes and Capped Call Modification

Loss on extinguishment of convertible notes and capped call modification relates to the partial extinguishment of our 2022 Notes and modification of a 2022 Notes capped call agreement.

Other Expense, Net

Other expense, net consists primarily of realized foreign currency gains and losses.

Comparison of the Three Months Ended March 31, 2022 and 2021

Revenue

	Three Months Ended March 31,				Change
(dollars in thousands)	2022		2021		$		%
Revenue	$	100,375	$	82,210	$	18,165		22.1	%

Revenue increased by $18.2 million for the three months ended March 31, 2022 compared to the same period in 2021. The increase was due to a $18.2 million increase in sales of our products driven by expansion of our customer base from 5,748 customers as of March 31, 2021 to 6,224 customers as of March 31, 2022, including increased sales to larger organizations with greater numbers of contacts and locations.

Cost of Revenue

	Three Months Ended March 31,						Change
(dollars in thousands)	2022			2021			$		%
Cost of revenue	$	31,857		$	25,280		$	6,577		26.0	%
Gross margin %		68	%		69	%

Cost of revenue increased by $6.6 million for the three months ended March 31, 2022 compared to the same period in 2021. The increase was primarily due to a $4.1 million increase in employee-related costs associated with our increased headcount from 374 employees as of March 31, 2021 to 511 employees as of March 31, 2022 net of a reduction in stock-based compensation expense as a result of expected reduced performance metric achievement, a $1.2 million increase in depreciation and amortization expense attributed to our fixed assets, acquired intangibles and capitalized software, a $0.9 million increase in hosting, software and messaging costs and other costs as well as a $0.4 million increase in office related expenses.

Gross margin percentage decreased due to our continued investment in personnel to support our growth.

Operating Expenses

Sales and Marketing Expense

	Three Months Ended March 31,						Change
(dollars in thousands)	2022			2021			$		%
Sales and marketing	$	41,816		$	34,527		$	7,289		21.1	%
% of revenue		42	%		42	%

Sales and marketing expense increased by $7.3 million for the three months ended March 31, 2022 compared to the same period in 2021. The increase was primarily due to a $4.8 million increase in employee-related costs, which includes stock-based compensation, associated with our increased headcount from 505 employees as of March 31, 2021 to 663 employees as of March 31, 2022 net of a reduction in stock-based compensation expense as a result of expected reduced performance metric achievement. The remaining increase was principally the result of a $1.6 million increase in advertising-related costs and trade show expenses, as well as a $0.6 million increase in office related expenses to support the sales team and a $0.3 million increase in software expenses.

Research and Development Expense

	Three Months Ended March 31,						Change
(dollars in thousands)	2022			2021			$		%
Research and development	$	23,559		$	18,079		$	5,480		30.3	%
% of revenue		23	%		22	%

Research and development expense increased by $5.5 million for the three months ended March 31, 2022 compared to the same period in 2021. The increase was primarily due to a $6.7 million increase in employee-related costs, which includes stock-based compensation, associated with our increased headcount from 365 employees as of March 31, 2021 to 593 employees as of March 31, 2022 net of a reduction in stock-based compensation expense as a result of expected reduced performance metric achievement, a $0.7 million increase in software related costs and a $0.3 million increase in office related expenses partially offset by a $0.3 million decrease in professional services to support research and development activities. A total of $2.2 million of internally developed software costs during the three months ended March 31, 2021 and $4.1 million of internally developed software costs during the three months ended March 31, 2022 were capitalized, resulting in a $1.9 million offset to the increase in the first quarter of 2022.

General and Administrative Expense

	Three Months Ended March 31,						Change
(dollars in thousands)	2022			2021			$			%
General and administrative	$	22,336		$	22,562		$	(226	)		(1.0	)%
% of revenue		22	%		27	%

General and administrative expense decreased by $0.2 million for the three months ended March 31, 2022 compared to the same period in 2021. The decrease was primarily due to a $2.6 million decrease in employee-related costs resulting from a reduction in stock-based compensation expense due to expected reduced performance metric achievement partially offset by increased employee-related costs due to increased headcount from 171 employees as of March 31, 2021 to 214 employees as of March 31, 2022, a $1.2 million decrease in credit loss expense and a $0.1 million decrease in our contingent consideration obligation. These decreases were offset by a $3.3 million increase in depreciation and amortization and a $0.4 million increase in professional services and office related expenses to support the administrative team.

Other Expense, Net

	Three Months Ended March 31,						Change
(dollars in thousands)	2022			2021			$		%
Other expense, net	$	(958	)	$	(9,364	)	$	8,406		89.8	%
% of revenue		(1	)%		(11	)%

40

Other expense, net decreased by $8.4 million for the three months ended March 31, 2022 compared to the same period in 2021 primarily due to a $5.3 million decrease in interest expense related to our convertible senior notes resulting from our adoption of ASU 2020-06 (see Notes 2 and 9 in the notes to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for a discussion of the impact of the adoption of ASU 2020-06), a $2.9 million decrease in loss on extinguishment of convertible notes and capped call modification and a $0.2 million decrease in other income (expense), net.

Income Taxes

	Three Months Ended March 31,						Change
(dollars in thousands)	2022			2021			$			%
Benefit from income taxes	$	1,078		$	5,813		$	(4,735	)		(81.5	)%
% of revenue		1	%		7	%

A portion of the losses incurred during the three months ended March 31, 2022 are expected to be realized in some jurisdictions during the year or recognized as a deferred tax asset as of December 31, 2022. Losses incurred for other operating jurisdictions required a valuation allowance. An income tax benefit of $1.1 million was recorded during the three months ended March 31, 2022 primarily attributable to losses benefited in foreign jurisdictions. The change in income tax benefit of $4.7 million for the three months ended March 31, 2022 as compared to the same period in 2021 was related to the change in valuation allowance and the realization of losses against deferred tax liabilities established for prior acquisitions.

Other Metrics

We regularly monitor a number of financial and operating metrics, including the following key metrics, to evaluate our business, measure our performance, identify trends affecting our business, formulate business plans, and make strategic decisions. Our other business metrics may be calculated in a manner different than similar other business metrics used by other companies (in thousands):

	Three Months Ended March 31,
	2022		2021
Adjusted EBITDA	$	2,553	$	5,283
Adjusted gross profit		72,486		60,533
Free cash flow		1,525		15,501

41

• Adjusted EBITDA. Adjusted EBITDA represents our net loss before interest and investment (income) expense, net, (benefit from) provision for income taxes, depreciation and amortization expense, loss on extinguishment of convertible notes and capped call modification, change in fair value of contingent consideration and stock-based compensation expense. We do not consider these items to be indicative of our core operating performance. The items that are non-cash include depreciation and amortization expense, loss on extinguishment of convertible notes and capped call modification, change in fair value of contingent consideration and stock-based compensation expense. Adjusted EBITDA is a measure used by management to understand and evaluate our core operating performance and trends and to generate future operating plans, make strategic decisions regarding the allocation of capital and invest in initiatives that are focused on cultivating new markets for our solutions. In particular, the exclusion of certain expenses in calculating adjusted EBITDA facilitates comparisons of our operating performance on a period-to-period basis. Adjusted EBITDA is not a measure calculated in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). We believe that adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors. Nevertheless, use of adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are: (1) although depreciation and amortization are non-cash charges, the capitalized software that is amortized will need to be replaced in the future, and adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; (2) adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; (3) adjusted EBITDA does not reflect the potentially dilutive impact of equity-based compensation; (4) adjusted EBITDA does not reflect tax payments or receipts that may represent a reduction or increase in cash available to us; and (5) other companies, including companies in our industry, may calculate adjusted EBITDA or similarly titled measures differently, which reduces the usefulness of the metric as a comparative measure. Because of these and other limitations, you should consider adjusted EBITDA alongside our other GAAP-based financial performance measures, net loss and our other GAAP financial results. The following table presents a reconciliation of adjusted EBITDA to net loss, the most directly comparable GAAP measure, for each of the periods indicated (in thousands):

	Three Months Ended March 31,
	2022			2021
Net loss	$	(19,073	)	$	(21,789	)
Interest and investment expense, net		1,238			6,427
Benefit from income taxes		(1,078	)		(5,813	)
Depreciation and amortization		15,434			10,843
Loss on extinguishment of convertible notes and capped call modification		—			2,888
Change in fair value of contingent consideration		(52	)		42
Stock-based compensation		6,084			12,685
Adjusted EBITDA	$	2,553		$	5,283

42

• Adjusted Gross Profit. Adjusted gross profit represents gross profit plus amortization of acquired intangibles and stock-based compensation. Adjusted gross profit is a measure used by management to understand and evaluate our core operating performance and trends and to generate future operating plans. The exclusion of stock-based compensation expense and amortization of acquired intangibles facilitates comparisons of our operating performance on a period-to-period basis. In the near term, we expect these expenses to continue to negatively impact our gross profit. Adjusted gross profit is not a measure calculated in accordance with GAAP. We believe that adjusted gross profit provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors. Nevertheless, our use of adjusted gross profit has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. You should consider adjusted gross profit alongside our other GAAP-based financial performance measures, gross profit and our other GAAP financial results. The following table presents a reconciliation of adjusted gross profit to gross profit, the most directly comparable GAAP measure, for each of the periods indicated (in thousands):

	Three Months Ended March 31,
	2022		2021
Gross profit	$	68,518	$	56,930
Amortization of acquired intangibles		3,151		2,604
Stock-based compensation		817		999
Adjusted gross profit	$	72,486	$	60,533

• Free Cash Flow. Free cash flow represents net cash from operating activities minus capital expenditures and capitalized software development costs. Free cash flow is a measure used by management to understand and evaluate our core operating performance and trends and to generate future operating plans. The exclusion of capital expenditures and amounts capitalized for internally-developed software facilitates comparisons of our operating performance on a period-to-period basis and excludes items that we do not consider to be indicative of our core operating performance. Free cash flow is not a measure calculated in accordance with GAAP. We believe that free cash flow provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors. Nevertheless, our use of free cash flow has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. You should consider free cash flow alongside our other GAAP-based financial performance measures, net cash provided by operating activities, and our other GAAP financial results. The following table presents a reconciliation of free cash flow to net cash for operating activities, the most directly comparable GAAP measure, for each of the periods indicated (in thousands):

	Three Months Ended March 31,
	2022			2021
Net cash provided by operating activities	$	7,702		$	19,808
Capital expenditures		(1,847	)		(1,812	)
Capitalized software development costs		(4,330	)		(2,495	)
Free cash flow	$	1,525		$	15,501

Additional Supplemental Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we provide investors with certain additional supplemental non-GAAP financial measures, including non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP sales and marketing expense, non-GAAP research and development expense, non-GAAP general and administrative expense, non-GAAP total operating expenses, non-GAAP operating income (loss) and non-GAAP net income (loss), which we collectively refer to as non-GAAP financial measures. These non-GAAP financial measures exclude all or a combination of the following (as reflected in the following reconciliation tables): stock-based compensation expense, amortization of acquired intangibles, change in fair value of contingent consideration, accretion of interest on convertible senior notes and loss on extinguishment of convertible notes and capped call modification and the tax impact of such adjustments. The tax impact of such adjustments was determined by recalculating the estimated annual effective tax rate utilizing non-GAAP pre-tax income estimated for the year and then applying the recalculated estimated annual effective tax rate to year-to-date non-GAAP income. The presentation of the non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. We use these non-GAAP financial measures for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures provide useful information about our operating results, enhance the overall understanding of past financial performance and future prospects and allow for greater transparency with respect to metrics used by our management in its financial and operational decision making. While our non-GAAP financial measures are an important tool for financial and operational decision making and for evaluating our own operating results over different periods of time, you should consider our non-GAAP financial measures alongside our GAAP financial results.

We exclude stock-based compensation expense which can vary based on plan design, share price, share price volatility, and the expected lives of equity instruments granted. We believe that providing non-GAAP financial measures that exclude stock-based compensation expense allow for more meaningful comparisons between our operating results from period to period because stock-based compensation expense does not represent a cash expenditure. We believe that excluding the impact of amortization of acquired intangibles allows for more meaningful comparisons between operating results from period to period as the intangibles are valued at the time of acquisition and are amortized over a period of several years after the acquisition. We believe that excluding the change in fair value of contingent consideration allows for more meaningful comparisons between operating results from period to period as it is non-operating in nature. We believe that excluding the impact of accretion of interest on convertible senior notes allows for more meaningful comparisons between operating results from period to period as accretion of interest on convertible senior notes relates to interest cost for the time value of money and are non-operating in nature. We believe that excluding loss on extinguishment of convertible notes and capped call modification allows for more meaningful comparisons between operating results from period to period as losses on the extinguishment of convertible notes and capped call modifications are non-operating in nature. We do not engage in the repurchase of convertible notes on a regular basis or in the ordinary course of business. Accordingly, we believe that excluding these expenses provides investors and management with greater visibility of the underlying performance of our business operations, facilitates comparison of our results with other periods and may also facilitate comparison with the results of other companies in our industry.

There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by other companies and exclude expenses that may have a material impact upon our reported financial results. Further, stock-based compensation expense has been and will continue to be for the foreseeable future a significant recurring expense in our business and an important part of the compensation provided to our employees.

Liquidity and Capital Resources

To date, we have financed our operations primarily through cash from sales to our customers, along with equity issuances and debt financing arrangements. Our principal source of liquidity is cash and cash equivalents totaling $492.1 million as of March 31, 2022. We have generated significant losses since inception and expect to continue to generate losses for the foreseeable future.

45

We believe that our cash and cash equivalent balances and the cash flows generated by our operations will be sufficient to satisfy our anticipated cash needs for working capital and capital expenditures for at least the next 12 months. However, our belief may prove to be incorrect, and we could utilize our available financial resources sooner than we currently expect. We believe that our financial resources will allow us to manage the anticipated impact of COVID-19 on our business operations for the foreseeable future, which could include delays in payments from our customers. The challenges posed by COVID-19 on our business could evolve rapidly. We will continue to evaluate our financial position in light of future developments, particularly those relating to COVID-19. Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth in the section of Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2021 and this Quarterly Report on Form 10-Q titled “Risk Factors.” We cannot assure you that we will be able to raise additional capital on acceptable terms or at all. In addition, if we fail to meet our operating plan during the next 12 months, our liquidity could be adversely affected.

Material Cash Requirements and Contractual Obligations

We expect to use cash primarily for operating activities, such as expansion of our sales and marketing operations, research and development activities and other working capital needs, such as salaries, bonuses, and other personnel cost and data center hosting costs, as well as payments for acquisitions of businesses and interest payments on our convertible senior notes. We expect to continue to finance our operations primarily through cash from sales to our customers and may consider future equity issuances and debt financing arrangements. Our commitments to settle contractual obligations include $825.0 million principal amount of indebtedness under the 2026 Notes, 2024 Notes and 2022 Notes (see Note 9 of the notes to consolidated financial statements) and lease obligations of $22.9 million (see Note 16 of the notes to condensed consolidated financial statements).

Cash Flows

The following table summarizes our cash flows (in thousands):

	Three Months Ended March 31,
	2022			2021
Cash, cash equivalents and restricted cash at beginning of period	$	492,758		$	475,630
Cash provided by operating activities		7,702			19,808
Cash used in investing activities		(6,224	)		(36,708	)
Cash provided by financing activities		1,129			284,792
Effects of exchange rates on cash, cash equivalents and restricted cash		(356	)		(315	)
Cash, cash equivalents and restricted cash at end of period	$	495,009		$	743,207

Sources of Funds

Our sources of funds include cash from sales to our customers, along with equity issuances and debt financing arrangements including our 2026 Notes, 2024 Notes and 2022 Notes.

Uses of Funds

Our historical uses of cash have primarily consisted of cash used for operating activities, such as expansion of our sales and marketing operations, research and development activities and other working capital needs.

Operating Activities

Our net loss and cash flows provided by or used in operating activities are significantly influenced by our investments in headcount and infrastructure to support our growth, marketing and sponsorship expenses, and our ability to bill and collect in a timely manner. Our net loss has been significantly greater than our use of cash for operating activities due to the inclusion of non-cash expenses and charges.

46

Operating activities generated $7.7 million in cash in the three months ended March 31, 2022, primarily as a result of non-cash operating expenses of $20.2 million and $6.5 million in cash provided as a result of changes in operating assets and liabilities which was offset by our net loss of $19.1 million. Specifically, we recognized non-cash charges aggregating to $15.4 million for depreciation and amortization of intangible assets, capitalized software development costs and property and equipment, $6.1 million for stock-based compensation, $4.0 million for amortization of deferred commissions, $1.2 million related to the accretion of interest on our convertible senior notes, $0.2 million for provision for credit losses, offset by $6.6 million for deferred income taxes and $0.1 million change in the fair value of our contingent consideration obligation. The net change in operating assets and liabilities of $6.5 million reflected an $11.4 million decrease in accounts receivable, an $8.0 million increase in deferred revenue a $3.2 million increase in accrued expenses and a $1.8 million decrease in other assets. These amounts were offset by a $6.2 million increase in deferred cost, a $6.1 million decrease in accounts payable, a $2.4 million increase in prepaid expenses, a $1.9 million decrease in accrued payroll and employee related liabilities and a $1.3 million decrease in other liabilities.

Operating activities generated $19.8 million in cash in the three months ended March 31, 2021, primarily as a result of non-cash operating expenses of $31.2 million and $10.4 million in cash provided as a result of changes in operating assets and liabilities which was offset by our net loss of $21.8 million. Specifically, we recognized non-cash charges aggregating to $12.7 million for stock-based compensation, $10.8 million for depreciation and amortization of intangible assets, capitalized software development costs and property and equipment, $6.3 million related to the accretion of interest on our convertible senior notes, $3.7 million for amortization of deferred commissions, $2.9 million loss on extinguishment of convertible notes and capped call modification, $1.6 million for provision for credit losses, offset by $6.7 million for deferred income taxes and $0.1 million in other non-cash adjustments. The net change in operating assets and liabilities of $10.4 million reflected an $11.5 million decrease in accounts receivable, an $8.4 million increase in deferred revenue and a $3.0 million increase in accrued expenses. These amounts were offset by a $3.5 million increase in deferred cost, a $2.8 million increase in other assets, a $2.1 million decrease in accrued employee related expenses due to timing of payments to employees, a $2.0 million net decrease in other liabilities, a $1.2 million increase in prepaid expenses for upfront payments made for prepaid software and insurance and a $0.9 million decrease in accounts payable.

Investing Activities

Our investing activities consist primarily of capital expenditures for capitalized software development costs, business acquisitions, property and equipment expenses and purchase and sales of short-term investments.

Investing activities used $6.2 million in cash in the three months ended March 31, 2022, which consists of a $4.3 million investment in software development, a $1.8 million in purchases of property and equipment and $0.1 million in other investing activities.

Investing activities used $36.7 million in cash in the three months ended March 31, 2021, which consists of $32.4 million of cash paid for the acquisition of Red Sky Technologies Inc., a $2.5 million investment in software development and $1.8 million in purchases of property and equipment.

Financing Activities

Cash generated by financing activities includes proceeds from the issuance of common stock from our follow-on public offering, borrowings under our convertible senior notes, proceeds from the partial termination of convertible note capped call hedges, proceeds from the exercise of employee stock options and contributions to our employee stock purchase plan. Cash used in financing activities includes payments for debt and offering issuance costs, purchases of convertible notes capped call hedges, extinguishment of debt, payment of contingent consideration and employee withholding liabilities from the exercise of restricted stock units.

Financing activities provided $1.1 million of cash in the three months ended March 31, 2022, which reflects $1.7 million from the issuance of stock under our employee stock purchase plan offset by a $0.6 million payment for employee withholding taxes related to the issuance of restricted stock units.

Financing activities provided $284.8 million of cash in the three months ended March 31, 2021, which reflects proceeds of $330.3 million from our 2026 Notes offering after deducting debt issuance cost and the cost for the capped call transactions entered into in connection with the 2026 Note offering, $2.5 million from the issuance of stock under our employee stock purchase plan and $1.6 million from the exercise of stock options. These amounts were offset by a $48.0 million payment for the repurchase of 2022 Notes offset by cash received for the partial termination of the 2022 Notes capped call options and a $1.6 million payment for employee withholding taxes related to the issuance of restricted stock units.

Critical Accounting Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of our condensed consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. We base our estimates and assumptions on historical experience and other factors that we believe to be reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates. The future effects of the COVID-19 pandemic on our results of operations, cash flows, and financial position are unclear; however, we believe we have used reasonable estimates and assumptions in preparing the condensed consolidated financial statements.

Except for the adoption of ASU 2020-06, there have been no changes to our critical accounting estimates described in the Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 25, 2022, that have had a material impact on our condensed consolidated financial statements and related notes.

Recently Issued Accounting Pronouncements

See Note 2 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for a summary of recently issued and adopted accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign exchange rates as well as, to a lesser extent, inflation.

Interest Rate Risk

Our investment portfolio is exposed to market risk from changes in interest rates. The fair market value of fixed rate securities may be adversely impacted by fluctuations in interest rates while income earned on floating rate securities may decline as a result of decreases in interest rates. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. We attempt to ensure the safety and preservation of our invested principal funds by limiting default risk, market risk and reinvestment risk. We mitigate default risk by investing in investment grade securities. We have historically maintained a relatively short average maturity for our investment portfolio, and we believe a hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not change the fair value of our interest sensitive financial instruments by a material amount. In addition, if a 100 basis point change in overall interest rates were to occur in 2022, our interest income would not change significantly in relation to amounts we would expect to earn, based on our cash, cash equivalents, and investments as of March 31, 2022.

Changes in interest rates may also impact gains or losses from the conversion of our outstanding convertible senior notes. In March 2021, we issued $375 million in aggregate principal amount of our 2026 Notes. In December 2019, we issued $450 million in aggregate principal amount of our 2024 Notes. In November 2017, we issued $115 million in aggregate principal amount of our 2022 Notes, of which $8 thousand remain outstanding. The 2026 Notes, 2024 Notes and 2022 Notes are convertible under certain circumstances, including trading price conditions related to our common stock, and upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock, at our election. In the second quarter of 2018, the last reported sale price of our common stock was at least 130% of the conversion price of the 2022 Notes for at least 20 trading days during a period of 30 consecutive trading days ending on, and including, the last trading day of the quarter, resulting in the 2022 Notes becoming convertible at the option of the holder during the third quarter of 2018. Based on the market price of the Company’s common stock during the 30 trading days preceding March 31, 2022, the 2022 Notes were not convertible at the option of the debt holder from April 1, 2022 through May 1, 2022. The 2026 Notes and 2024 Notes were not convertible at March 31, 2022.

Upon conversion, we are required to record a gain or loss for the difference between the fair value of the debt to be extinguished and its corresponding net carrying value. The fair value of the debt to be extinguished depends on our then-current incremental borrowing rate. If our incremental borrowing rate at the time of conversion is higher or lower than the implied interest rate of the 2026 Notes, 2024 Notes and 2022 Notes, we will record a gain or loss in our consolidated statement of operations during the period in which the 2026 Notes, 2024 Notes and 2022 Notes are extinguished. An incremental borrowing rate that is a hypothetical 100 basis points lower than the implicit interest rate upon conversion of the 2026 Notes, 2024 Notes and 2022 Notes would result in a loss of approximately $8.3 million.

48

We are exposed to interest rate risk in the ordinary course of our business. Our cash, cash equivalents and investments include cash in readily available checking and money market accounts and marketable securities. These securities are not dependent on interest rate fluctuations that may cause the principal amount of these assets to fluctuate.

We had cash and cash equivalents of $492.1 million as of March 31, 2022, which consisted of bank deposits and money market funds. To date, fluctuations in interest income have not been significant.

We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure.

Foreign Currency Exchange Risk

We have foreign currency risks related to our revenue and operating expenses denominated in currencies other than our functional currency, the U.S. dollar, principally British Pounds, Euro, Norwegian Krone, Swedish Kronor and other foreign currencies. Movements in foreign currencies in which we transact business could significantly affect future net earnings. We do not currently engage in any hedging activity to reduce our potential exposure to currency fluctuations, although we may choose to do so in the future. A hypothetical 10% change in foreign exchange rates during any of the periods presented would not have had a material impact on our consolidated financial statements. As our international operations grow, we will continue to reassess our approach to manage our risk relating to fluctuations in foreign currency rate.

Inflation Risk

We do not believe that inflation has had a material effect on our business, financial condition or results of operations historically. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control

There were no changes in our internal control over financial reporting identified in management's evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. In response to the COVID-19 pandemic, our employees began working from home starting in March 2020. Management is continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact to their design and operating effectiveness.

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our global organization have been detected. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

In April 2022, a putative class action lawsuit was filed in the United States District Court for the Central District of California against the Company, Jaime Ellertson, Patrick Brickley, and David Meredith (the Company’s former Chief Executive Officer) by Sylebra Capital Partners Master Fund Ltd, Sylebra Capital Parc Master Fund, and Sylebra Capital Menlo Master Fund. The lawsuit alleges violations of the federal securities laws by us and certain of our officers and directors arising out of purported misrepresentations in the information we provided to investors regarding our organic and inorganic revenue growth, the status of integrating acquisitions, and the impact of COVID-19 on our business, which allegedly artificially inflated the price of our stock during the period November 4, 2019 to February 24, 2022. We are not able to estimate the amount of the loss allegedly suffered by members of the putative class or the amount of legal costs and internal efforts associated with defending ourselves and our officers and directors. We believe that the allegations and claims made in this lawsuit are wholly without merit and intend to defend the action vigorously. Even if we were to prevail, this litigation could continue to be costly and time-consuming and divert the attention of our management and key personnel from our business operations. During the course of the litigation, we anticipate announcements of the results of hearings and motions, and other interim developments related to the litigation. If securities analysts or investors regard these announcements as negative, the market price of our common stock may decline. If we are unsuccessful in defending ourselves in this litigation, this lawsuit could materially and adversely affect our business, financial condition, results of operations, and cash flows.

From time to time, we may become involved in other legal proceedings or be subject to claims arising in the ordinary course of our business. Except for the claim described above, we are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, financial condition, results of operations or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors.

We operate in a rapidly changing environment that involves a number of risks, which could materially affect our business, financial condition or future results, some of which are beyond our control. Except as set forth below, during the three months ended March 31, 2022, there have been no material changes in our risk factors from those disclosed in Part I-Item 1A under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 25, 2022.

Implementation of our 2022 Strategic Realignment or simplification strategies may not be successful, which could affect our ability to increase our revenues or could reduce our profitability.

On May 3, 2022, our Board of Directors approved a program (the “2022 Strategic Realignment”) to strategically realign our resources in order to accelerate and grow our investments in our largest growth opportunities while streamlining our operations. This program is in support of the 2022 strategic initiatives to simplify our business and accelerate the integration of recent acquisitions, and will help to drive the financial outcomes of sustainable growth and improved profitability and cash flow. The 2022 Strategic Realignment program includes a targeted realignment and reduction of headcount, facilities and other third-party spend. We expect to record in the aggregate approximately $5 million to $9 million in restructuring charges associated with the 2022 Strategic Realignment and $8 million to $12 million in business transformation costs associated with the 2022 Strategic Realignment. A significant portion of these charges will result in future cash expenditures, and the program is expected to be substantially completed by the first half of fiscal 2023.

Although we believe that the 2022 Strategic Realignment will reduce overhead costs, enhance operational simplicity, and result in improved Adjusted EBITDA, we cannot guarantee that the 2022 Strategic Realignment will achieve or sustain the targeted benefits, or that the benefits, even if achieved, will be adequate to meet our long-term profitability and operational expectations. Risks associated with the continuing impact of the 2022 Strategic Realignment also include additional unexpected costs and negative impacts on our cash flows from operations and liquidity, employee attrition beyond our intended reduction in force and adverse effects on employee morale, diversion of management attention, adverse effects to our reputation as an employer, which could make it more difficult for us to hire new employees in the future, and potential failure or delays to meet operational and growth targets due to the loss of qualified employees. If we do not realize the expected benefits or synergies of the 2022 Strategic Realignment, our business, financial condition, cash flows and results of operations could be negatively impacted.

Activist investor actions threatened or commenced against us could cause us to incur substantial costs, divert management’s attention and resources, cause uncertainty about the strategic direction of our business and adversely affect our business, financial position and results of operations.

In connection with the upcoming 2022 Annual Meeting of our Shareholders (the “2022 Annual Meeting”), Ancora Holdings Group, LLC (together with its affiliates, “Ancora”), has announced that it intends to withhold support for four directors nominated by the Board of Directors for reelection. In addition, Ancora has made multiple public statements in recent months regarding the Company’s strategy, Board of Directors and management team. These types of actions pursued by Ancora or other shareholders, including any future proxy contests, could conflict with our strategic direction, could divert the attention of our Board of Directors, management, and employees, be costly and time-consuming, and may disrupt the momentum in our business and operations, as well as our ability to execute our strategic plan. These types of actions may also create perceived uncertainties as to the future direction of our business or strategy, which may be exploited by our competitors and may make it more difficult to attract and retain qualified personnel, and may impact our relationship with investors, vendors, customers and other third parties. These types of actions could also impact the market price and the volatility of our common stock. In addition, we may choose to initiate, or may become subject to, litigation as a result of shareholder actions, which would serve as a further distraction to our Board of Directors, senior management and employees and could require us to incur significant additional costs.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

(2) Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

The condensed consolidated balance sheet as of December 31, 2021, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, statements of stockholders’ equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2022 or any future period.

Effective January 1, 2022, the Company adopted the requirements of Accounting Standards Update (“ASU”) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, as discussed in this Note 2 and Note 9.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Assets and liabilities which are subject to judgment and use of estimates include the determination of the period of benefit for deferred commissions, relative stand-alone selling price for identified performance obligations in the Company’s revenue transactions, allowances for credit losses, the fair value of assets acquired and liabilities assumed in business combinations, the fair value of contingent consideration, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, contingencies, and the valuation and assumptions underlying stock-based compensation. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, the Company engages valuation specialists to assist with management’s determination of the valuation of its fair values of assets acquired and liabilities assumed in business combinations, convertible senior notes, and certain market-based performance equity awards.

There have been significant changes to the global economic situation as a consequence of the COVID-19 pandemic. There continue to be uncertainties with respect to macroeconomic conditions as a result of the pandemic and otherwise and there may be future periods of global instability and volatility in markets where the Company conducts business which could cause changes to estimates as a result of the financial circumstances. Such changes to estimates could potentially result in impacts that would be material to the consolidated financial statements, particularly with respect to the timing of revenue recognition resulting from potential implementation delays, evaluating the recoverability of long-lived assets with finite useful lives for impairment and estimates of credit losses for accounts receivables and contract assets. No impairments were recorded as of the balance sheet date; however, due to significant uncertainty surrounding the situation, management's judgment regarding this could change in the future. As of the date of issuance of these financial statements, the Company’s results of operations have not been significantly impacted by the COVID-19 pandemic; however, the Company continues to monitor the situation.

Concentrations of Credit and Business Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable.

The Company maintains cash and cash equivalent balances at several banks. Accounts located in the United States are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. From time to time, balances may exceed amounts insured by the FDIC. The Company has not experienced any losses in such amounts.

The Company’s accounts receivable are generally unsecured and are derived from revenue earned from customers primarily located in the United States, Norway, Netherlands, Sweden and the United Kingdom and are generally denominated in U.S. Dollars, Norwegian Krone, Euro, Swedish Kronor or British Pounds. Each reporting period, the Company reevaluates each customer’s ability to satisfy credit obligations and maintains an allowance for credit risk based on the evaluations. No single customer comprised more than 10% of the Company’s total revenue for the three months ended March 31, 2022 and 2021. No single customer comprised more than 10% of the Company’s gross accounts receivable as of March 31, 2022. One customer comprised approximately 10% of the Company’s gross accounts receivable balance at December 31, 2021.  

Cash and Cash Equivalents

The Company considers all highly liquid instruments with original maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents consist of funds deposited into money market funds. Cash and cash equivalents are recorded at cost, which approximates fair value.

Restricted Cash

The Company’s restricted cash balance primarily consists of cash held at a financial institution for collateral against performance on the Company’s customer contracts and certain other cash deposits for specific purposes.

Significant Accounting Policies

There have been no changes to the Company’s significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 25, 2022, that have had a material impact on the Company’s condensed consolidated financial statements and related notes.

Revenue Recognition

The Company derives its revenues primarily from subscription services and professional services. Revenues are recognized when control of services is transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those services.

The Company determines revenue recognition through the following steps:

• Identification of the contract, or contracts, with a customer;

• Identification of the performance obligations in the contract;

• Determination of the transaction price;

• Allocation of the transaction price to the performance obligations in the contract; and

• Recognition of revenue when, or as, the Company satisfies a performance obligation.

Subscription Services Revenues

Subscription services revenues primarily consist of fees that provide customers access to one or more of the Company’s hosted applications for critical event management, with routine customer support. Revenue is generally recognized over time on a ratable basis over the contract term beginning on the date that the Company’s service is made available to the customer. All services are recognized using an output measure of progress looking at time elapsed as the contract generally provides the customer equal benefit throughout the contract period. The Company’s subscription contracts are generally two years or longer in length, billed annually in advance, and non-cancelable.

Professional Services Revenues

Professional services revenues primarily consist of fees for deployment and optimization services, as well as training. The majority of the Company’s consulting contracts revenue is recognized over time as the services are performed. For contracts billed on a fixed price basis, revenue is recognized over time based on the proportion performed.

Software License Revenues

The Company also sells software and related post contract support for on premises usage as well as professional services, hardware and hosting. The Company’s on premises license transactions are generally perpetual in nature and are recognized at a point in time when made available to the customer for use. Significant judgment is required to determine the standalone selling prices for each distinct performance obligation in order to allocate the transaction price for purposes of revenue recognition. Making this judgment of estimating a standalone selling price involves consideration of overall pricing objectives, market conditions and other factors, including the value of the Company’s other similar contracts, the applications sold, customer demographics, geographic locations, and the number and types of users within the Company’s contracts. The significant judgment was primarily due to using such considerations to estimate the price that each distinct performance obligation would be sold for on a standalone basis because such performance obligations are typically sold together on a bundled basis. Changes in these estimates of standalone selling prices can have a material effect on the amount of revenue recognized from each distinct performance obligation.

Contracts with Multiple Performance Obligations

Most of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis for those performance obligations with stable observable prices and then the residual method applied for any performance obligation that has pricing which is highly variable. The Company determines the standalone selling prices based on the Company’s overall pricing objectives, taking into consideration market conditions and other factors, including the value of the Company’s contracts, pricing when certain services are sold on a standalone basis, the applications sold, customer demographics, geographic locations, and the volume of services and users.

Returns

The Company does not offer rights of return for its products and services in the normal course of business. 

Customer Acceptance

The Company’s contracts with customers generally do not include customer acceptance clauses.

Trade and Other Receivables

Trade and other receivables are primarily comprised of trade receivables that are recorded at the invoice amount, net of an allowance for credit risk, which is not material. Other receivables represent unbilled receivables related to subscription and professional services contracts, net of an allowance for credit losses, which is not material.

Deferred Costs

Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Subscription-related commissions costs are deferred and then amortized on a straight-line basis over a period of benefit that the Company has determined to be four years. Sales commissions attributable to professional services are expensed within twelve months of selling the service to the customer. The Company has determined the period of benefit by taking into consideration its customer contracts, its technology and other factors. Sales commissions attributed to renewals are not material and are not commensurate with initial and growth sales. Amortization of deferred commissions is included in sales and marketing expenses in the accompanying condensed consolidated statements of operations.

Deferred Revenue

Deferred revenue consists of amounts that have been invoiced and for which the Company has the right to bill, but that have not been recognized as revenue because the related goods or services have not been transferred. Deferred revenue that will be realized during the succeeding 12-month period is recorded as current, and the remaining deferred revenue is recorded as non-current.

In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts generally do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, not to receive financing from its customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with revenue recognized ratably over the contract period.

Recently Adopted Accounting Pronouncements

ASU 2021-10

In November 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance. ASU 2021-10 requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The Company adopted ASU 2021-10 on January 1, 2022 on a prospective basis. The adoption of this standard did not have an impact on the Company’s condensed consolidated financial statements.

ASU 2021-04

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU 2021-04 requires accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after the modification or exchange based on the economic substance of the modification or exchange. The recognition of the modification depends on the nature of the transaction in which the equity-classified written call option is modified. If there is more than one element in a transaction (for example, if the modification involves both a debt modification and an equity issuance), then the guidance requires allocating the effect of the option modification to each element. The Company adopted ASU 2021-04 on January 1, 2022 on a prospective basis. The adoption of this standard did not have an impact on the Company’s condensed consolidated financial statements.

ASU 2020-06

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 reduces the number of accounting models for convertible instruments by eliminating two of the three models in Accounting Standards Codification (“ASC”) 470-20, Debt—Debt with Conversion and Other Options, that require separate accounting for embedded conversion features, amends the requirements for a contract that is potentially settled in an entity’s own shares to be classified in equity, and amends certain guidance on the computation of earnings per share for convertible instruments and contracts on an entity’s own equity. The Company adopted the standard on January 1, 2022 using the modified retrospective approach.

Upon adoption of ASU 2020-06, the Company no longer separately presents in equity the embedded conversion feature of the 0% convertible senior notes due March 15, 2026 (the “2026 Notes”), 0.125% convertible senior notes due December 15, 2024 (the “2024 Notes”) and 1.50% convertible senior notes due November 1, 2022 (the “2022 Notes”) (collective, the “Convertible Senior Notes”). Instead, the Company accounts for the Convertible Senior Notes wholly as debt. Applying the separation models prior to the adoption of ASU 2020-06 to the Convertible Senior Notes involved the recognition of a debt discount, which was amortized to interest expense via the effective interest method. The elimination of the cash conversion model will reduce reported interest expense in periods subsequent to adoption.

Adoption of ASU 2020-06 resulted in an adjustment to the carrying amount of the convertible senior notes, deferred tax liabilities, additional paid-in capital and a cumulative catch-up adjustment to the opening balance of accumulated deficit; however, prior-period information, including basic and diluted loss per share of common stock, has not been adjusted as a result of applying the modified retrospective approach and continue to be reported under the accounting standards in effect for the prior period. The adoption of ASU 2020-06 had no impact on total cash provided from or used in operating, financing, or investing activities in the Company’s condensed consolidated statements of cash flows. For details on the impact of the Company’s adoption of ASU 2020-06, see Note 9.

Recently Issued Accounting Guidance Not Yet Adopted

ASU 2021-08

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires the recognition and measurement of contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers. Considerations to determine the amount of contract assets and contract liabilities to record at the acquisition date include the terms of the acquired contract, such as timing of payment, identification of each performance obligation in the contract and allocation of the contract transaction price to each identified performance obligation on a relative standalone selling price basis as of contract inception. ASU 2021-08 is effective for the Company beginning in the first quarter of 2023. ASU 2021-08 should be applied prospectively for acquisitions occurring on or after the effective date of the amendments. Early adoption of the proposed amendments would be permitted, including adoption in an interim period. The Company is currently assessing the impact this standard will have on the Company’s condensed consolidated financial statements.

Other accounting standard updates effective for interim and annual periods beginning after December 31, 2021 are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

(6) Fair Value Measurements

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of the short maturity of these items.

Certain assets, including long-lived assets, goodwill and intangible assets are also subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review. For the three months ended March 31, 2022 and year ended December 31, 2021, no impairments were identified of those assets requiring measurement at fair value on a non-recurring basis.

The following table summarizes the Company's financial assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy. Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands):

	As of March 31, 2022
	Quoted		Significant
	Prices in		Other		Significant
	Active		Observable		Unobservable

Total financial assets	$	409,692	$	—	$	—	$	409,692
Liabilities:
Contingent consideration	$	—	$	—	$	59	$	59
Total financial liabilities	$	—	$	—	$	59	$	59

The Company classifies and discloses fair value measurements in one of the following three categories of fair value hierarchy:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and liabilities.

Level 2 - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company’s assets that are measured by management at fair value on a recurring basis are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company did not have any transfers into and out of Level 1 or Level 2 during the three months ended March 31, 2022. 

The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value and such instruments are classified as Level 1 and are included in cash and cash equivalents on the condensed consolidated balance sheets.

The following tables summarize the changes in Level 3 financial instruments (in thousands):

Fair value at December 31, 2020	$	10,619
Contingent consideration from RedSky acquisition		9,135
Adjustment for one2many acquisition		(690	)
Adjustment for SnapComms acquisition		732
Foreign currency translation		(465	)
Fair value at March 31, 2021	$	19,331

Fair value at December 31, 2021	$	59
Adjustment for Anvil acquisition		(52	)
Foreign currency translation		(1	)
Fair value at March 31, 2022	$	6

The valuation of the contingent consideration was derived using estimates of the probability of achievement within specified time periods based on projections of future revenue metrics per the terms of the applicable agreements. These include estimates of the Company’s assessment of the probability of meeting such results, with the probability-weighted earn-out using a Monte Carlo Simulation Model then discounted to estimate fair value. Fair value is estimated using the probability weighted cash flow estimate closer to the measurement date. The various operating performance measures included in these contingent consideration agreements primarily relate to product revenue. As these are unobservable inputs, the contingent consideration liabilities are included in Level 3 inputs.

During the three months ended March 31, 2022, as a result of assessing the probabilities of payment for the potential contingent consideration for The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited (collectively, “Anvil”) through June 30, 2023, the Company recognized a decrease in the fair value of Anvil’s contingent consideration obligation in the amount of $0.1 million.

The Company estimates the fair value of the convertible senior notes based on market-observable inputs (Level 2). As of March 31, 2022 and December 31, 2021, the fair value of the 2026 Notes was determined to be $326.7 million and $318.3 million, respectively, and the principal amount of the notes was $375.0 million for each period. As of March 31, 2022 and December 31, 2021, the fair value of 2024 Notes was determined to be $407.9 million and $440.6 million, respectively, and the principal amount of the notes was $450.0 million for each period. As of March 31, 2022 and December 31, 2021, the fair value of the 2022 Notes was determined to be $11 thousand and $16 thousand, respectively, and the principal amount of the notes was $8 thousand for each period.

Business Combinations [Abstract]

Business Combinations

(8) Business Combinations

The Company accounted for the following acquisitions using the acquisition method of accounting for business combinations under ASC 805, Business Combinations, which required that the assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the acquisition date. The excess of the purchase price over the net fair value of the assets and liabilities was recorded as goodwill. This goodwill includes the know-how of the assembled workforce, the ability of the workforce to further improve technology and product offerings, customer relationships and the expected cash flows resulting from these efforts. Goodwill may also include expected synergies resulting from the complementary strategic fit these businesses bring to existing operations.

Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives and the expected future cash flows and related discount rates, can materially impact the Company’s results of operations. Significant inputs used for the model included the amount of cash flows, the expected period of the cash flows and the discount rates. Significant estimation was required by management in determining the fair value of the customer relationship intangible assets, deferred revenue and contingent consideration liabilities. The significant estimation is primarily due to the judgmental nature of the inputs to the valuation models used to measure the fair value of these intangible assets, deferred revenue and contingent consideration liabilities, as well as the sensitivity of the respective fair values to the underlying significant assumptions. The Company used the income approach to measure the fair value of these intangible assets, a discounted cash flow approach for deferred revenue and a Monte Carlo simulation model to measure the fair value of the contingent consideration liabilities. The significant assumptions used to estimate the fair value of the intangible assets, deferred revenue and contingent consideration

liabilities included forecasted revenues from existing customers, existing customer attrition rates, estimated costs required to fulfill the deferred revenue obligation and forecasted revenues for the contingent consideration earnout period. When estimating the significant assumptions to be used in the valuation the Company includes a consideration of current industry information, market and economic trends, historical results of the acquired business, nature of the performance obligations associated with the deferred revenue and other relevant factors. These significant assumptions are forward-looking and could be affected by future economic and market conditions. The valuation of the contingent consideration was derived using estimates of the probability of achievement within specified time periods based on projections of future revenue metrics per the terms of the applicable agreements. These include estimates of the Company’s assessment of the probability of meeting such results, with the probability-weighted earn-out using a Monte Carlo Simulation Model then discounted to estimate fair value. Fair value is estimated using the probability weighted cash flow estimate closer to the measurement date. The various operating performance measures included in these contingent consideration agreements primarily relate to product revenue. 

The business acquisitions discussed below are included in the Company’s results of operations from their respective dates of acquisition.

2021 Acquisitions

During the year ended December 31, 2021, the Company acquired Red Sky Technologies Inc., xMatters Holdings, Inc. and The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited. These acquisitions were not material and neither the investment in the assets nor the results of operations of these acquisitions were significant to the Company’s consolidated financial position or results of operations, and thus pro forma information is not required to be presented.

Red Sky Technologies Inc.

On January 15, 2021, the Company entered into a Stock Purchase Agreement with Red Sky Technologies Inc. (“RedSky”) pursuant to which the Company purchased all of the issued and outstanding shares of stock of RedSky for a base consideration of $55.4 million, net of cash acquired. The Company paid $32.4 million in cash, net of cash acquired, and issued 162,820 newly issued shares of the Company’s common stock at closing. On the date of this acquisition, the average price of the Company’s common stock on the Nasdaq Global Market was $141.46 per share. In addition to the base purchase price, there was also a potential contingent payment of up to $30 million that was eligible to be earned by the sellers based on certain revenue targets through the contractual measurement period. At the date of the acquisition, the Company preliminarily assessed the probability of RedSky meeting the revenue metrics through the contractual measurement period and recorded a $9.1 million initial fair value of contingent consideration as part of the purchase price allocation. During the year ended December 31, 2021, the Company paid $0.4 million in cash and issued 4,058 shares of the Company’s common stock to settle RedSky’s contingent consideration liability. The Company acquired RedSky for its E911 incident response solutions platform to enhance the Company’s CEM suite of solutions as well as market penetration and customer reach.

xMatters Holdings, Inc.

On April 6, 2021, the Company and xMatters Holdings, Inc. (“xMatters”) signed a definitive agreement pursuant to which the Company agreed to purchase all of the issued and outstanding shares of stock of xMatters. This acquisition closed on May 7, 2021. The Company purchased all of the issued and outstanding shares of stock of xMatters for a base consideration of $242.6 million. The Company paid $178.1 million in cash and issued 555,332 newly issued shares of the Company’s common stock at closing. On the date of this acquisition, the average price of the Company’s common stock on the Nasdaq Global Market was $116.12 per share. The Company acquired xMatters for its service reliability platforms to enhance the Company’s CEM suite of solutions as well as market penetration and customer reach.

The weighted average useful life of all identified acquired intangible assets is 8.13 years. The average useful lives for acquired technologies, customer relationships and trade names are 3.0 years, 9.0 years and 5.0 years, respectively. Identifiable intangible assets with definite lives are amortized over the period of estimated benefit using the straight-line method. The straight-line method of amortization represents the Company’s best estimate of the period of expected cash flows of the identifiable intangible assets.

The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to the integration of xMatters’ products with the Company's other solutions. The Company believes that the factors listed above in relation to the purchase of xMatters support the amount of goodwill recorded as a result of the purchase price paid for the acquisition, in relation to other acquired tangible and intangible assets. The resulting goodwill from the xMatters acquisition is not deductible for income tax purposes.

For the year ended December 31, 2021, the Company incurred transaction costs of $1.5 million in connection with the xMatters acquisition.

The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited

On November 4, 2021, the Company entered into an agreement with the shareholders of The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited (collectively, “Anvil”) pursuant to which the Company purchased all of the issued and outstanding share capital of Anvil for a base consideration of $161.5 million. The Company paid $70.2 million in cash at closing, acquired net purchase liabilities of $1.6 million and issued $89.7 million consideration loan notes. On November 10, 2021, the Company issued 574,639 newly issued shares of the Company’s common stock to settle consideration loan notes issued on the acquisition date. In addition to the base purchase price, there is also a potential contingent payment of up to $0.8 million that may be paid to the sellers on or before June 30, 2023. At the date of the acquisition, the Company preliminarily assessed the probability of the contingent consideration payment and recorded a $0.1 million preliminary fair value as part of the purchase price allocation. During the three months ended March 31, 2022, the Company recognized a decrease in the fair value of Anvil’s contingent consideration obligation in general and administrative expenses in the condensed consolidated statements of operations in the amount of $0.1 million. The Company acquired Anvil for its travel risk management, operational resiliency and occupational health solutions platforms to enhance the Company’s CEM suite of solutions as well as market penetration and customer reach.

As the Company finalizes its estimation of the fair value of the assets acquired and liabilities assumed, additional adjustments may be recorded during the measurement period (a period not to exceed 12 months). The initial accounting is incomplete as of March 31, 2022 for the acquired assets and liabilities as the Company is currently in the process of completing the assessment of valuation inputs and assumptions as well as completing the assessment of the tax attributes of the business combination. The finalization of the acquisition accounting valuation assessment may result in a change in the valuation of the deferred tax assets and liabilities, deferred revenue and intangible assets, along with the opening working capital accounts, which could have a material impact on the Company’s results of operations and financial position.

During the three months ended March 31, 2022, the Company recognized an increase of $2.0 million in customer relationship intangible assets, a $0.5 million increase in deferred tax liabilities and a $1.6 million decrease to goodwill.

The following table summarizes the preliminary estimated fair value of the assets acquired and the liabilities assumed, which were recorded as of the acquisition date, as well as the aggregate consideration for the acquisition of Anvil made by the Company (in thousands):

	Anvil

Accounts receivable	$	2,361
Property and equipment		204
Trade names		2,600
Acquired technology		3,800

Consideration paid
Cash paid, net of cash acquired	$	63,911
Consideration loan notes issued		89,655

Total	$	153,626

The weighted average useful life of all identified acquired intangible assets is 8.07 years. The average useful lives for acquired technologies, customer relationships and trade names are 4.0 years, 9.0 years and 5.0 years, respectively. Identifiable intangible assets with definite lives are amortized over the period of estimated benefit using the straight-line method. The straight-line method of amortization represents the Company’s best estimate of the period of expected cash flows of the identifiable intangible assets.

The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to the integration of Anvil’s products with the Company's other solutions. The acquisition of Anvil will bring in house the expertise and experience to manage medical and travel-related situations for the Company’s travel risk management offerings to new and existing customers. The Company believes that the factors listed above in relation to the purchase of Anvil support the amount of goodwill recorded as a result of the purchase price paid for the acquisition, in relation to other acquired tangible and intangible assets. The resulting goodwill from the Anvil acquisition is not deductible for income tax purposes.

For the year ended December 31, 2021, the Company incurred transaction costs of $1.4 million in connection with the Anvil acquisition.

0% Convertible Senior Notes Due 2026

In March 2021, the Company issued $375.0 million aggregate principal amount of 0% convertible senior notes due 2026, including $50.0 million aggregate principal amount of 2026 Notes issued upon the initial purchasers’ exercise in full of their option to purchase additional 2026 Notes. The 2026 Notes will mature on March 15, 2026, unless earlier redeemed or repurchased by the Company or converted by the holders pursuant to their terms. The Company will pay special interest, if any, at the Company’s election as the sole remedy relating to the failure to comply with certain reporting obligations and under certain circumstances.

The 2026 Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank National Association, as trustee (the “2026 Notes Indenture”). The 2026 Notes are unsecured and rank: senior in right of payment to the Company’s indebtedness that is expressly subordinated in right of payment to the 2026 Notes; equal in right of payment to the Company’s existing and future indebtedness that is not so subordinated, including its 1.50% convertible senior notes due 2022 (see 1.50% Convertible Senior Notes Due 2022 below) and 0.125% convertible senior notes due 2024 (see 0.125% Convertible Senior Notes Due 2024 below); effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness and other liabilities incurred by the Company’s subsidiaries.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election.

The 2026 Notes have an initial conversion rate of 5.5341 shares of common stock per $1,000 principal amount of 2026 Notes. This represents an initial effective conversion price of approximately $180.70 per share of common stock and approximately 2.1 million shares issuable upon conversion. Throughout the term of the 2026 Notes, the conversion rate may be adjusted upon the occurrence of certain events. Holders of the 2026 Notes will not receive any cash payment representing accrued and unpaid special interest, if any, upon conversion of a 2026 Note, except in limited circumstances. Accrued but unpaid special interest, if any, will be deemed to be paid by cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock paid or delivered, as the case may be, to the holder upon conversion of a 2026 Note.

Holders may convert all or a portion of their 2026 Notes prior to the close of business on the business day immediately preceding December 15, 2025, in multiples of $1,000 principal amount, only under the following circumstances:

• during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

• during the five business day period after any ten consecutive trading day period (the “2026 Notes Measurement Period”), in which the “trading price” (as the term is defined in the 2026 Notes Indenture) per $1,000 principal amount of notes for each trading day of such 2026 Notes Measurement Period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

• if the Company calls such notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the notes called (or deemed called) for redemption; or

• upon the occurrence of specified corporate events.

On or after December 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their 2026 Notes at the conversion rate at any time regardless of whether the conditions set forth above have been met.

As of March 31, 2022, the 2026 Notes are not yet convertible. The 2026 Notes are classified as long-term on the condensed consolidated balance sheets as of March 31, 2022 and December 31, 2021 as it is the Company’s intent to settle all of the debt at maturity or to settle in shares if exercised by the debt holder prior to maturity.

The 2026 Notes are not redeemable by the Company prior to March 20, 2024. The Company may redeem for cash all or any portion of the 2026 Notes, at its option, on or after March 20, 2024 if the last reported sale price of the Company's common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date.

The 2026 Notes consist of the following (in thousands):

	As of			As of
	March 31, 2022			December 31, 2021
Liability component:
Principal	$	375,000		$	375,000

Net carrying amount	$	366,648		$	277,739
Equity component (1)		—			99,000

⁽¹⁾ Upon adoption of ASU 2020-06, the Company no longer separately presents the embedded conversion feature in equity. As of December 31, 2021, the equity component was recorded in the consolidated balance sheet within additional paid-in capital, net of $3.0 million transaction costs in equity and net of $3.4 million for taxes.

The following table sets forth total interest expense recognized related to the 2026 Notes (in thousands):

	Three Months Ended March 31,
	2022		2021
Amortization of debt discount and transaction costs	$	522	$	1,056

Effective interest rates were 0.6% and 7.3% for the three months ended March 31, 2022 and 2021, respectively.

The fair value of the 2026 Notes, which was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, quoted price of the 2026 Notes in an over-the-counter market (Level 2), and carrying value of debt instruments (prior to the adoption of ASU 2020-06, carrying value excluded the equity component of the Company’s 2026 Notes classified in equity) were as follows (in thousands):

	As of March 31, 2022				As of December 31, 2021
	Fair Value		Carrying Value		Fair Value		Carrying Value
2026 Notes	$	326,681	$	366,648	$	318,311	$	277,739

In connection with the issuance of the 2026 Notes, the Company entered into capped call transactions with certain counterparties affiliated with the initial purchasers and other financial institutions. The capped call transactions are expected generally to reduce potential dilution to the Company’s common stock upon any conversion of the 2026 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2026 Notes, as the case may be, with such reduction and/or offset subject to a cap. Under the capped call transactions, the Company purchased capped call options that in the aggregate relate to the total number of shares of the Company’s common stock underlying the 2026 Notes, with an initial strike price of approximately $180.70 per share, which corresponds to the initial conversion price of the 2026 Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the 2026 Notes, and with a cap price of approximately $258.14. The cost of the purchased capped calls of $35.1 million was recorded to shareholders’ equity and will not be re-measured.

Based on the closing price of the Company’s common stock of $43.64 on March 31, 2022, the if-converted value of the 2026 Notes was less than their respective principal amounts.

0.125% Convertible Senior Notes Due 2024

In December 2019, the Company issued $450.0 million aggregate principal amount of 0.125% convertible senior notes due 2024, including $75.0 million aggregate principal amount of 2024 Notes issued upon the initial purchasers’ exercise in full of their option to purchase additional 2024 Notes. The 2024 Notes will mature on December 15, 2024, unless earlier redeemed or repurchased by the Company or converted by the holders pursuant to their terms. Interest is payable semiannually in arrears on June 15 and December 15 of each year, commencing on June 15, 2020.

The 2024 Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank National Association, as trustee (the “2024 Notes Indenture”). The 2024 Notes are unsecured and rank: senior in right of payment to the Company’s indebtedness that is expressly subordinated in right of payment to the 2024 Notes; equal in right of payment to the Company’s existing and future indebtedness that is not so subordinated, including its 2026 Notes and 2022 Notes; effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness and other liabilities incurred by the Company’s subsidiaries.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. The Company’s current intention is to settle the conversion in shares of common stock if a conversion were to occur.

The 2024 Notes have an initial conversion rate of 8.8999 shares of common stock per $1,000 principal amount of 2024 Notes. This represents an initial effective conversion price of approximately $112.36 per share of common stock and approximately 4.0 million shares issuable upon conversion. Throughout the term of the 2024 Notes, the conversion rate may be adjusted upon the occurrence of certain events. Holders of the 2024 Notes will not receive any cash payment representing accrued and unpaid interest, if any, upon conversion of a 2024 Note, except in limited circumstances.

Holders may convert all or a portion of their 2024 Notes prior to the close of business on the business day immediately preceding June 15, 2024, in multiples of $1,000 principal amount, only under the following circumstances:

• during any calendar quarter commencing after the calendar quarter ending on March 31, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

• during the five business day period after any ten consecutive trading day period (the “2024 Notes Measurement Period”), in which the “trading price” (as the term is defined in the 2024 Notes Indenture) per $1,000 principal amount of notes for each trading day of such 2024 Notes Measurement Period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

• if the Company calls such notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or

• upon the occurrence of specified corporate events.

On or after June 15, 2024 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their 2024 Notes at the conversion rate at any time regardless of whether the conditions set forth above have been met.

Stock Plans and Stock-Based Compensation

(11) Stock Plans and Stock-Based Compensation

The Company’s 2016 Equity Incentive Plan (the “2016 Plan”) became effective on September 15, 2016. The 2016 Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and performance share awards to employees, directors and consultants of the Company. The number of shares of common stock reserved for issuance under the 2016 Plan will automatically increase on January 1 of each year by 3% of the number of shares of the Company’s capital stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s board of directors.

2016 Employee Stock Purchase Plan

The Company’s Employee Stock Purchase Plan (the “2016 ESPP”) became effective on September 15, 2016. The number of shares reserved for issuance under the 2016 ESPP will automatically increase on January 1 of each year by the lesser of 200,000 shares of the Company’s common stock, 1% of the number of shares of the Company’s common stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s board of directors.

The 2016 ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of up to 15% through payroll deductions of their eligible compensation, subject to any plan limitations. The 2016 ESPP provides for separate six-month offering periods beginning each March and September of each fiscal year.

On each purchase date, eligible employees will purchase the Company’s stock at a price per share equal to 85% of the lesser of (i) the fair market value of the Company’s common stock on the offering date or (ii) the fair market value of the Company’s common stock on the purchase date.

For the three months ended March 31, 2022 and 2021, 58,747 and 23,499 shares of common stock were purchased under the 2016 ESPP, respectively. The Company recorded stock-based compensation expense of $0.4 million and $0.5 million for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, unrecognized compensation cost related to the 2016 ESPP was $0.6 million which will be amortized over a weighted-average period of 0.42 years. 

The fair value of shares issuable under the 2016 ESPP is determined using the Black-Scholes option pricing model with the following weighted average assumptions: 

	Three Months Ended March 31,
	2022		2021
Employee Stock Purchase Plan:
Expected term (in years) (1)		0.50		0.50
Expected volatility (2)	65%		60%
Risk-free interest rate (3)	0.86%		0.06%
Dividend rate (4)	0%		0%

⁽¹⁾ The expected term represents the contractual term of the 2016 ESPP;

⁽²⁾ The expected volatility of the Company’s common stock on the date of grant is based on the weighted average of the Company’s historical volatility as a public company, the implied volatility of publicly-traded options on the Company’s common stock and the volatilities of publicly traded peer companies that are reasonably comparable to the Company’s own operations;

⁽³⁾ The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the grant; and

⁽⁴⁾ The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on the Company’s common stock.

Stock Options

Stock option awards are granted with an exercise price equal to the fair market value of the Company’s common stock at the date of grant based on the closing market price of its common stock as reported on The Nasdaq Global Market. The option awards generally vest over four years and are exercisable any time after vesting. The stock options expire ten years after the date of grant.

There were no stock options granted during the three months ended March 31, 2022 and 2021. The Company recorded stock-based compensation expense of $0.1 million and $0.4 million for the three months ended March 31, 2022 and 2021, respectively, attributed to stock options.    

The total intrinsic value of options exercised for the three months ended March 31, 2022 and 2021 was less than $0.1 million and $6.3 million, respectively. This intrinsic value represents the difference between the fair market value of the Company’s common stock on the date of exercise and the exercise price of each option. Based on the fair market value of the Company’s common stock at March 31, 2022 and 2021, the total intrinsic value of all outstanding options was $3.1 million and $21.5 million, respectively.

Total unrecognized compensation cost related to nonvested stock options was less than $0.1 million as of March 31, 2022 and is expected to be recognized over a weighted average period of 0.07 years. The amount of cash received from the exercise of stock options during the three months ended March 31, 2022 and 2021 was less than $0.1 million and $1.6 million, respectively.

The following table summarizes the Company’s stock option activity:

	Stock options outstanding			Weighted average exercise price
Outstanding at December 31, 2021		157,740		$	23.83
Exercised		(725	)		24.58
Forfeited		(125	)		33.06
Outstanding at March 31, 2022		156,890			23.82

Stock options outstanding, vested and expected to vest and exercisable are as follows:

	As of March 31, 2022
	Number of shares		Remaining contractual life (years)		Weighted- average exercise price
Outstanding		156,890		4.85	$	23.82

Restricted Stock Units

During the three months ended March 31, 2022, the Company granted 1,268,273 restricted stock units (“RSUs”) to members of its senior management and certain other employees pursuant to the 2016 Plan. There were 62,976 RSUs that vested during the three months ended March 31, 2022. The Company accounts for RSUs issued to employees at fair value, based on the market price of the Company’s common stock on the date of grant. The weighted-average grant date fair values of RSUs granted during the three months ended March 31, 2022 and 2021 were $39.78 and $132.34, respectively. The fair values of RSUs that vested during the three months ended March 31, 2022 and 2021, were $5.4 million and $4.0 million, respectively. During the three months ended March 31, 2022 and 2021, the Company recorded $7.0 million and $5.9 million, respectively, of stock-based compensation related to the RSUs.

As of March 31, 2022, there was $87.5 million of unrecognized compensation expense related to unvested RSUs which is expected to be recognized over a weighted-average period of approximately 2.55 years. For RSUs subject to graded vesting, the Company recognizes compensation cost on a straight-line basis over the service period for the entire award.

Performance-Based Restricted Stock Units

On February 9, 2022, the Compensation Committee of the Company’s Board of Directors approved a modification to the performance thresholds of the Company’s performance-based restricted stock unit (“PSU”) awards which affected 785 grantees and excluded our Named Executive Officers for 2021. The modified PSUs vest based on the Company achieving certain revenue growth thresholds which range from 1% to 40% compounded annual growth over the measurement period. For the portion of the PSUs where the expectation of the achievement of performance conditions changed from improbable prior to the modification to probable post-modification, the Company accounted for this change as a Type III modification under ASC 718, Compensation—Stock Compensation. The modification date fair value for the PSUs was $55.31. As of the modification date, total incremental stock-based compensation expense was $17.5 million which will be recognized over the remaining service periods of the PSU less subsequent forfeitures.

During the three months ended March 31, 2022, the Company granted 379,229 PSUs to members of its management pursuant to the 2016 Plan. There were 5,584 PSUs that vested during the three months ended March 31, 2022. The PSUs, other than those modified on February 9, 2022 as described above, generally vest based on the Company achieving certain revenue growth thresholds which ranged from 20% to 40% compounded annual growth for grants through 2020 and 15% to 35% compounded annual growth for grants starting in 2021 over a measurement period of two years for the first 50% of PSUs and three years for the remaining PSUs. The vesting of the PSUs is subject to the employee’s continued employment with the Company through the date of achievement. During the three months ended March 31, 2022, the share price of the Company’s common stock on the date of issuance of the PSUs ranged from $36.59 to $55.31 per share. The fair value is based on the value of the Company’s common stock at the date of issuance and the probability of achieving the performance metric. Compensation cost is adjusted in future periods for subsequent changes in the expected outcome of the performance related conditions. The weighted-average grant date fair values of PSUs granted during the three months ended March 31, 2022 and 2021 were $38.79 and $133.06, respectively.

During the three months ended March 31, 2022 and 2021, the Company recognized a credit of $(1.4 million) and $5.9 million, respectively, of stock compensation expense in connection with the PSU awards. During the three months ended March 31, 2022, prior to the PSU modification, as a result of forecasted decreases in the compounded annual growth rate, the Company reduced the expected achievement of performance metrics and recognized a reduction in stock-based compensation expense. This reduction was partially offset by the incremental compensation expense recognized for the modified PSUs. As of March 31, 2022, there was $28.7 million of unrecognized compensation expense related to unvested PSUs which is expected to be recognized over a weighted-average period of approximately 2.00 years. Compensation cost is recognized under the accelerated method and is adjusted in future periods for subsequent changes in the expected outcome of the performance related conditions.

The following table summarizes the Company’s RSU and PSU activity:

	Number of Shares
Outstanding at December 31, 2021		1,579,738
Granted		1,647,502
Vested		(68,560	)
Forfeited		(307,617	)
Outstanding at March 31, 2022		2,851,063

Market-Based Grants

During the three months ended March 31, 2022, the Company issued market-based grants, which are payable in cash to partially settle a vendor contract. The grants vest contingent upon the achievement of pre-determined market and service conditions. Cash payment at settlement will range from zero to approximately $1.3 million based on the Company’s total stockholder return (“TSR”) relative to the performance of peer companies through September 2023. The market-based grants are classified as a liability on the Company’s balance sheet and will be remeasured at each reporting period until settlement. The grant date fair value of the market-based grants was $0.4 million. The key estimates used in the Monte-Carlo simulation were a risk-free rate of 1.97%, dividend yield of zero, expected term of 1.50 years and volatility of 58%. During the three months ended March 31, 2022, the Company recognized an immaterial amount of stock compensation expense in connection with these awards. As of March 31, 2022, there was $0.4 million of unrecognized compensation expense related to the market-based grants which is expected to be recognized over approximately 0.22 years.

Stock-Based Compensation Expense

Basic and Diluted Net Loss Per Share

3 Months Ended

Mar. 31, 2022

Earnings Per Share [Abstract]

Basic and Diluted Net Loss Per Share

(12) Basic and Diluted Net Loss per Share

Basic net loss per common share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive shares of common stock. Basic and diluted net loss per share of common stock were the same for all periods presented as the impact of all potentially dilutive securities outstanding was anti-dilutive. The Company uses the if converted method for convertible senior notes for calculating any potential dilutive effect on diluted loss per share.

The following common equivalent shares were excluded from the diluted net loss per share calculation because their inclusion would have been anti-dilutive:

	As of March 31,
	2022		2021
Convertible senior notes		6,080,480		6,125,864
Stock-based compensation grants		3,007,953		1,602,837
Total		9,088,433		7,728,701

In connection with the issuance of the 2026 Notes in March 2021, the Company paid $35.1 million to enter into capped call option agreements to reduce the potential dilution to holders of the Company’s common stock upon conversion of the 2026 Notes. In connection with the issuance of the 2024 Notes in December 2019, the Company paid $44.9 million to enter into capped call option agreements to reduce the potential dilution to holders of the Company’s common stock upon conversion of the 2024 Notes. In connection with the issuance of the 2022 Notes in November 2017, the Company paid $12.9 million to enter into capped call option agreements to reduce the potential dilution to holders of the Company’s common stock upon conversion of the 2022 Notes. In March 2021 and December 2019, the Company partially terminated capped call options related to the 2022 Notes and received $10.6 million and $5.8 million, respectively. In March 2021, the Company also modified a capped call agreement entered into in connection with the 2022 Notes and recognized modification expense of $0.2 million in loss on extinguishment of convertible notes and capped call modification on the condensed consolidated statement of operations. The capped call option agreements are excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive.

Reserve for Unissued Shares of Common Stock

The Company is required to reserve and keep available out of its authorized but unissued shares of common stock such number of shares sufficient for the exercise of all shares granted and available for grant under the Company’s 2008 Equity Incentive Plan, 2016 Plan and 2016 ESPP. The amount of such shares of the Company’s common stock reserved for these purposes at March 31, 2022 was 6.7 million shares. Additionally, the Company is required to reserve and keep available out of its authorized but unissued shares of common stock shares that become issuable pursuant to the terms of the 2026 Notes, 2024 Notes and 2022 Notes.

Income Tax Disclosure [Abstract]

Income Taxes

(13) Income Taxes

The Company is subject to income tax in the United States as well as other tax jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income tax. The Company does not provide for U.S. deferred income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are reinvested indefinitely.

The Company’s tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual tax rate changes, the Company makes a cumulative adjustment in that quarter. The Company’s quarterly tax provision, and its quarterly estimate of its annual effective tax rate, are subject to significant volatility due to several factors, including the Company’s ability to accurately predict its pre-tax income and loss in multiple jurisdictions.

For the three months ended March 31, 2022 and 2021, the Company recorded a benefit from income taxes of $1.1 million and a benefit from income taxes of $5.8 million, respectively, resulting in an effective tax rate of 5.35% and an effective rate of 21.06%, respectively. The benefit of $1.1 million generated in the three months ended March 31, 2022, was primarily generated by losses in foreign jurisdiction which are expected to be realized in the current or future years. For the three months ended March 31, 2021, there were deferred tax liabilities recognized in connection with the preliminary purchase accounting for the Company’s completed acquisitions. Certain of such deferred tax liabilities will be a source of future taxable income to realize a portion of Company’s deferred tax assets, which resulted in a discrete tax benefit of approximately $5.8 million related to U.S. acquired entities being recognized during the three months ended March 31, 2021.

As of March 31, 2022, the Company had gross tax-effected unrecognized tax provision of $1.8 million which, if recognized, would favorably impact the effective tax rate. The Company’s existing tax positions will continue to generate an increase in unrecognized tax benefits in subsequent periods. The Company’s policy is to record interest and penalties related to unrecognized tax benefits as a component of income tax expense. During the three months ended March 31, 2022 and 2021, the amounts recorded related to the accrual of interest and penalties were immaterial in each period.

Segment Reporting [Abstract]

Segment Information

(14) Segment information

The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assess the Company’s financial and operational performance. Patrick Brickley, Executive Vice President, Chief Financial Officer and Treasurer and Interim Co-Chief Executive Officer, and Vernon Irvin, Executive Vice President, Chief Revenue Officer and Interim Co-Chief Executive Officer are interim CODMs of the Company. While the Company has applications that address multiple use cases, the Company’s applications generally operate on and leverage a single technology platform and are deployed and sold in an identical way. In addition, the Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. As a result, the Company has determined that the Company’s business operates in a single operating segment. Since the Company operates as one operating segment, all required financial segment information can be found in the consolidated financial statements.

Contract Assets

The Company does not have material amounts of contract assets since revenue is recognized as control of goods is transferred or as services are performed. There are a small number of professional services that may occur over a period of time, but that period of time is generally very short in duration. Any contract assets that may arise are recorded in other assets in the Company’s condensed consolidated balance sheet net of an allowance for credit losses.

Contract Liabilities

The Company’s contract liabilities consist of advance payments and deferred revenue. The Company’s contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. The Company classifies advance payments and deferred revenue as current or noncurrent based on the timing of when it expects to recognize revenue. Generally, all contract liabilities are expected to be recognized within one year and are included in deferred revenue in the Company’s condensed consolidated balance sheet. The noncurrent portion of deferred revenue is included and separately disclosed in the Company’s condensed consolidated balance sheet.

Deferred Costs

Current deferred costs, which primarily consist of deferred sales commissions, were $16.1 million and $15.8 million as of March 31, 2022 and December 31, 2021, respectively. Noncurrent deferred costs, which primarily consist of deferred sales commissions, were $18.9 million and $17.0 million as of March 31, 2022 and December 31, 2021, respectively. During the three months ended March 31, 2022 and 2021, amortization expense for the deferred costs was $4.0 million and $3.7 million, respectively. There was no impairment loss in relation to the costs capitalized for the three months ended March 31, 2022 and the year ended December 31, 2021, respectively.

Deferred Revenue

During the three months ended March 31, 2022 and 2021, $83.7 million and $59.7 million, respectively, of subscription services, license and other revenue was recognized and was included in the deferred revenue balances at the beginning of the respective period.

During the three months ended March 31, 2022 and 2021, $4.0 million and $4.5 million, respectively, of professional services revenue was recognized and was included in the deferred revenue balances at the beginning of the respective period.

As of March 31, 2022, approximately $450.3 million of revenue is expected to be recognized from remaining performance obligations for subscription and other contracts. The Company expects to recognize revenue on approximately $284.6 million of these remaining performance obligations over the next 12 months, with the balance recognized thereafter.      

As of March 31, 2022, approximately $19.1 million of revenue is expected to be recognized from remaining performance obligations for professional services contracts. The Company expects to recognize revenue on approximately $16.5 million of these remaining performance obligations over the next 12 months, with the balance recognized thereafter.

Leases

(16) Leases

The Company’s leases relate primarily to office facilities that expire on various dates from 2022 through 2029. The terms of the Company's non-cancelable operating lease arrangements typically contain fixed lease payment which increases over the term of the lease at fixed rates, rent holidays and provide for additional renewal periods. Lease expense is recognized over the term of the lease on a straight-line basis. All of the Company’s leases are classified as operating leases. The Company has determined that periods covered by options to extend the Company’s leases are excluded from the lease term as the Company is not reasonably certain the Company will exercise such options.

The Company records its right-of-use (“ROU”) asset within other assets (long term) and its operating lease liabilities within other current and long-term liabilities.

Litigation

In April 2022, a putative class action lawsuit was filed in the United States District Court for the Central District of California against the Company, Jaime Ellertson, Patrick Brickley, and David Meredith (the Company’s former Chief Executive Officer) by Sylebra Capital Partners Master Fund Ltd, Sylebra Capital Parc Master Fund, and Sylebra Capital Menlo Master Fund. The lawsuit alleges violations of the federal securities laws by the Company and certain of its officers and directors arising out of purported misrepresentations in the information the Company provided to investors regarding the Company’s organic and inorganic revenue growth, the status of integrating acquisitions, and the impact of COVID-19 on the Company’s business, which allegedly artificially inflated the price of the Company’s stock during the period November 4, 2019 to February 24, 2022. The Company is not able to estimate the amount of the loss allegedly suffered by members of the putative class or the amount of legal costs and internal efforts associated with defending the Company and the Company’s officers and directors. The Company believes that the allegations and claims made in this lawsuit are wholly without merit and intends to defend the action vigorously. Even if the Company were to prevail, this litigation could continue to be costly and time-consuming and divert the attention of the Company’s management and key personnel from the Company’s business operations. During the course of the litigation, the Company anticipates announcements of the results of hearings and motions, and other interim developments related to the litigation. If securities analysts or investors regard these announcements as negative, the market price of the Company’s common stock may decline. If the Company is unsuccessful in defending itself in this litigation, this lawsuit could materially and adversely affect the Company’s business, financial condition, results of operations and cash flows.

From time to time the Company may become involved in other legal proceedings or be subject to claims arising in the ordinary course of business. Although the results of ordinary course litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business, financial condition, results of operations or cash flows. Regardless of the outcome, litigation can have an adverse impact because of defense and settlement costs, diversion of management resources and other factors.

Employee Contracts

The Company has entered into employment contracts with certain of the Company’s executive officers which provide for at-will employment. However, under the provisions of the contracts, the Company would incur severance obligations of up to twelve months of the executive’s annual base salary for certain events, such as involuntary terminations.

2022 Strategic Realignment

On May 3, 2022, the Board of Directors of the Company approved a program (the “2022 Strategic Realignment”) to strategically realign the Company’s resources in order to accelerate and grow the Company’s investments in the Company’s largest growth opportunities while streamlining the Company’s operations. This program is in support of the 2022 strategic initiatives to simplify the Company’s business and accelerate the integration of recent acquisitions, and will help to drive the financial outcomes of sustainable growth and improved profitability and cash flow. The 2022 Strategic Realignment program includes a targeted realignment and reduction of headcount, facilities and other third-party spend.

The 2022 Strategic Realignment charges will result in future cash expenditures of approximately $13 million to $21 million the majority of which the Company expects to be paid during fiscal 2022 with the remainder paid through fiscal 2028.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

The condensed consolidated balance sheet as of December 31, 2021, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, statements of stockholders’ equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2022 or any future period.

Effective January 1, 2022, the Company adopted the requirements of Accounting Standards Update (“ASU”) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, as discussed in this Note 2 and Note 9.

Principles of Consolidation

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Assets and liabilities which are subject to judgment and use of estimates include the determination of the period of benefit for deferred commissions, relative stand-alone selling price for identified performance obligations in the Company’s revenue transactions, allowances for credit losses, the fair value of assets acquired and liabilities assumed in business combinations, the fair value of contingent consideration, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, contingencies, and the valuation and assumptions underlying stock-based compensation. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, the Company engages valuation specialists to assist with management’s determination of the valuation of its fair values of assets acquired and liabilities assumed in business combinations, convertible senior notes, and certain market-based performance equity awards.

There have been significant changes to the global economic situation as a consequence of the COVID-19 pandemic. There continue to be uncertainties with respect to macroeconomic conditions as a result of the pandemic and otherwise and there may be future periods of global instability and volatility in markets where the Company conducts business which could cause changes to estimates as a result of the financial circumstances. Such changes to estimates could potentially result in impacts that would be material to the consolidated financial statements, particularly with respect to the timing of revenue recognition resulting from potential implementation delays, evaluating the recoverability of long-lived assets with finite useful lives for impairment and estimates of credit losses for accounts receivables and contract assets. No impairments were recorded as of the balance sheet date; however, due to significant uncertainty surrounding the situation, management's judgment regarding this could change in the future. As of the date of issuance of these financial statements, the Company’s results of operations have not been significantly impacted by the COVID-19 pandemic; however, the Company continues to monitor the situation.

Concentrations of Credit and Business Risk

Concentrations of Credit and Business Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable.

The Company maintains cash and cash equivalent balances at several banks. Accounts located in the United States are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. From time to time, balances may exceed amounts insured by the FDIC. The Company has not experienced any losses in such amounts.

The Company’s accounts receivable are generally unsecured and are derived from revenue earned from customers primarily located in the United States, Norway, Netherlands, Sweden and the United Kingdom and are generally denominated in U.S. Dollars, Norwegian Krone, Euro, Swedish Kronor or British Pounds. Each reporting period, the Company reevaluates each customer’s ability to satisfy credit obligations and maintains an allowance for credit risk based on the evaluations. No single customer comprised more than 10% of the Company’s total revenue for the three months ended March 31, 2022 and 2021. No single customer comprised more than 10% of the Company’s gross accounts receivable as of March 31, 2022. One customer comprised approximately 10% of the Company’s gross accounts receivable balance at December 31, 2021.  

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid instruments with original maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents consist of funds deposited into money market funds. Cash and cash equivalents are recorded at cost, which approximates fair value.

Restricted Cash

Restricted Cash

The Company’s restricted cash balance primarily consists of cash held at a financial institution for collateral against performance on the Company’s customer contracts and certain other cash deposits for specific purposes.

Significant Accounting Policies

Significant Accounting Policies

There have been no changes to the Company’s significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 25, 2022, that have had a material impact on the Company’s condensed consolidated financial statements and related notes.

Revenue Recognition

Revenue Recognition

The Company derives its revenues primarily from subscription services and professional services. Revenues are recognized when control of services is transferred to the Company’s customers in an amount that reflects the consideration it expects to be entitled to in exchange for those services.

The Company determines revenue recognition through the following steps:

• Identification of the contract, or contracts, with a customer;

• Identification of the performance obligations in the contract;

• Determination of the transaction price;

• Allocation of the transaction price to the performance obligations in the contract; and

• Recognition of revenue when, or as, the Company satisfies a performance obligation.

Subscription Services Revenues

Subscription services revenues primarily consist of fees that provide customers access to one or more of the Company’s hosted applications for critical event management, with routine customer support. Revenue is generally recognized over time on a ratable basis over the contract term beginning on the date that the Company’s service is made available to the customer. All services are recognized using an output measure of progress looking at time elapsed as the contract generally provides the customer equal benefit throughout the contract period. The Company’s subscription contracts are generally two years or longer in length, billed annually in advance, and non-cancelable.

Professional Services Revenues

Professional services revenues primarily consist of fees for deployment and optimization services, as well as training. The majority of the Company’s consulting contracts revenue is recognized over time as the services are performed. For contracts billed on a fixed price basis, revenue is recognized over time based on the proportion performed.

Software License Revenues

The Company also sells software and related post contract support for on premises usage as well as professional services, hardware and hosting. The Company’s on premises license transactions are generally perpetual in nature and are recognized at a point in time when made available to the customer for use. Significant judgment is required to determine the standalone selling prices for each distinct performance obligation in order to allocate the transaction price for purposes of revenue recognition. Making this judgment of estimating a standalone selling price involves consideration of overall pricing objectives, market conditions and other factors, including the value of the Company’s other similar contracts, the applications sold, customer demographics, geographic locations, and the number and types of users within the Company’s contracts. The significant judgment was primarily due to using such considerations to estimate the price that each distinct performance obligation would be sold for on a standalone basis because such performance obligations are typically sold together on a bundled basis. Changes in these estimates of standalone selling prices can have a material effect on the amount of revenue recognized from each distinct performance obligation.

Contracts with Multiple Performance Obligations

Most of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis for those performance obligations with stable observable prices and then the residual method applied for any performance obligation that has pricing which is highly variable. The Company determines the standalone selling prices based on the Company’s overall pricing objectives, taking into consideration market conditions and other factors, including the value of the Company’s contracts, pricing when certain services are sold on a standalone basis, the applications sold, customer demographics, geographic locations, and the volume of services and users.

Returns

The Company does not offer rights of return for its products and services in the normal course of business. 

Customer Acceptance

The Company’s contracts with customers generally do not include customer acceptance clauses.

Trade and Other Receivables

Trade and Other Receivables

Trade and other receivables are primarily comprised of trade receivables that are recorded at the invoice amount, net of an allowance for credit risk, which is not material. Other receivables represent unbilled receivables related to subscription and professional services contracts, net of an allowance for credit losses, which is not material.

Deferred Costs

Deferred Costs

Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Subscription-related commissions costs are deferred and then amortized on a straight-line basis over a period of benefit that the Company has determined to be four years. Sales commissions attributable to professional services are expensed within twelve months of selling the service to the customer. The Company has determined the period of benefit by taking into consideration its customer contracts, its technology and other factors. Sales commissions attributed to renewals are not material and are not commensurate with initial and growth sales. Amortization of deferred commissions is included in sales and marketing expenses in the accompanying condensed consolidated statements of operations.

Deferred Revenue

Deferred Revenue

Deferred revenue consists of amounts that have been invoiced and for which the Company has the right to bill, but that have not been recognized as revenue because the related goods or services have not been transferred. Deferred revenue that will be realized during the succeeding 12-month period is recorded as current, and the remaining deferred revenue is recorded as non-current.

In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts generally do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, not to receive financing from its customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with revenue recognized ratably over the contract period.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

ASU 2021-10

In November 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance. ASU 2021-10 requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The Company adopted ASU 2021-10 on January 1, 2022 on a prospective basis. The adoption of this standard did not have an impact on the Company’s condensed consolidated financial statements.

ASU 2021-04

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU 2021-04 requires accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after the modification or exchange based on the economic substance of the modification or exchange. The recognition of the modification depends on the nature of the transaction in which the equity-classified written call option is modified. If there is more than one element in a transaction (for example, if the modification involves both a debt modification and an equity issuance), then the guidance requires allocating the effect of the option modification to each element. The Company adopted ASU 2021-04 on January 1, 2022 on a prospective basis. The adoption of this standard did not have an impact on the Company’s condensed consolidated financial statements.

ASU 2020-06

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 reduces the number of accounting models for convertible instruments by eliminating two of the three models in Accounting Standards Codification (“ASC”) 470-20, Debt—Debt with Conversion and Other Options, that require separate accounting for embedded conversion features, amends the requirements for a contract that is potentially settled in an entity’s own shares to be classified in equity, and amends certain guidance on the computation of earnings per share for convertible instruments and contracts on an entity’s own equity. The Company adopted the standard on January 1, 2022 using the modified retrospective approach.

Upon adoption of ASU 2020-06, the Company no longer separately presents in equity the embedded conversion feature of the 0% convertible senior notes due March 15, 2026 (the “2026 Notes”), 0.125% convertible senior notes due December 15, 2024 (the “2024 Notes”) and 1.50% convertible senior notes due November 1, 2022 (the “2022 Notes”) (collective, the “Convertible Senior Notes”). Instead, the Company accounts for the Convertible Senior Notes wholly as debt. Applying the separation models prior to the adoption of ASU 2020-06 to the Convertible Senior Notes involved the recognition of a debt discount, which was amortized to interest expense via the effective interest method. The elimination of the cash conversion model will reduce reported interest expense in periods subsequent to adoption.

Adoption of ASU 2020-06 resulted in an adjustment to the carrying amount of the convertible senior notes, deferred tax liabilities, additional paid-in capital and a cumulative catch-up adjustment to the opening balance of accumulated deficit; however, prior-period information, including basic and diluted loss per share of common stock, has not been adjusted as a result of applying the modified retrospective approach and continue to be reported under the accounting standards in effect for the prior period. The adoption of ASU 2020-06 had no impact on total cash provided from or used in operating, financing, or investing activities in the Company’s condensed consolidated statements of cash flows. For details on the impact of the Company’s adoption of ASU 2020-06, see Note 9.

Recently Issued Accounting Guidance Not Yet Adopted

ASU 2021-08

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires the recognition and measurement of contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers. Considerations to determine the amount of contract assets and contract liabilities to record at the acquisition date include the terms of the acquired contract, such as timing of payment, identification of each performance obligation in the contract and allocation of the contract transaction price to each identified performance obligation on a relative standalone selling price basis as of contract inception. ASU 2021-08 is effective for the Company beginning in the first quarter of 2023. ASU 2021-08 should be applied prospectively for acquisitions occurring on or after the effective date of the amendments. Early adoption of the proposed amendments would be permitted, including adoption in an interim period. The Company is currently assessing the impact this standard will have on the Company’s condensed consolidated financial statements.

Other accounting standard updates effective for interim and annual periods beginning after December 31, 2021 are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Schedule of Assumptions Used in Determining Fair Value of Shares Issuable

The fair value of shares issuable under the 2016 ESPP is determined using the Black-Scholes option pricing model with the following weighted average assumptions: 

	Three Months Ended March 31,
	2022		2021
Employee Stock Purchase Plan:
Expected term (in years) (1)		0.50		0.50
Expected volatility (2)	65%		60%
Risk-free interest rate (3)	0.86%		0.06%
Dividend rate (4)	0%		0%

⁽¹⁾ The expected term represents the contractual term of the 2016 ESPP;

⁽²⁾ The expected volatility of the Company’s common stock on the date of grant is based on the weighted average of the Company’s historical volatility as a public company, the implied volatility of publicly-traded options on the Company’s common stock and the volatilities of publicly traded peer companies that are reasonably comparable to the Company’s own operations;

⁽³⁾ The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the grant; and

⁽⁴⁾ The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on the Company’s common stock.
