SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, which involve substantial risks and uncertainties. These statements reflect the current views of our senior management with respect to our future events, strategies and financial trends and performance. These forward-looking statements include statements with respect to our business, expenses, strategies, losses, growth plans, product and client initiatives, market growth projections, and our industry. Statements that include the words “expect,” “intend,” “plan,” “believe,” “project,” “forecast,” “estimate,” “may,” “should,” “anticipate” and similar statements of a future or forward-looking nature identify forward-looking statements for purposes of the federal securities laws or otherwise.
Forward-looking statements address matters that involve risks and uncertainties. Accordingly, there are or will be important factors that could cause our actual results to differ materially from those indicated in these statements. These factors include the information under the caption "Risk Factors" set forth in Part 1, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and Part II, Item 1A, of this Quarterly Report, which we encourage you to carefully read, and include the following:
adverse economic conditions, including the impact of macroeconomic challenges, including continued inflation, increased interest rates, supply chain disruptions, decreased economic output and fluctuations in currency rates, the impact of the Russia-Ukraine conflict, the impact of the conflict in the Middle East, and other factors, may continue to harm our business;
if we are unable to attract new clients or sell additional services and functionality to our existing clients, our revenue and revenue growth will be harmed;
if our existing clients terminate their subscriptions or reduce their subscriptions and related usage, or fail to grow subscriptions at the rate they have in the past or that we might expect, our revenues and gross margins will be harmed, and we will be required to spend more money to grow our client base;
because a significant percentage of our revenue is derived from existing clients, downturns or upturns in new sales will not be immediately reflected in our operating results and may be difficult to discern;
if we fail to manage our technical operations infrastructure, our existing clients may experience service outages, our new clients may experience delays in the deployment of our solution and we could be subject to, among other things, claims for credits or damages;
further development of our AI solutions may not be successful and may result in reputational harm and our future operating results could be materially harmed;
we have established, and are continuing to increase, our network of technology solution distributors and resellers to sell our solution; our failure to effectively develop, manage, and maintain this network could materially harm our revenues;
our quarterly and annual results may fluctuate significantly, including as a result of the timing and success of new product and feature introductions by us, may not fully reflect the underlying performance of our business and may result in decreases in the price of our common stock;
if we are unable to attract and retain highly skilled leaders and other employees, our business and results of operations may be adversely affected;
our historical growth may not be indicative of our future growth, and even if we continue to grow rapidly, we may fail to manage our growth effectively;
failure to adequately retain and expand our sales force will impede our growth;
the AI technology and features incorporated into our solution include new and evolving technologies that may present both legal and business risks;
the use of AI by our workforce may present risks to our business;
the contact center software solutions market is subject to rapid technological change, and we must develop and sell incremental and new solutions in order to maintain and grow our business;
our growth depends in part on the success of our strategic relationships with third parties and our failure to successfully maintain, grow and manage these relationships could harm our business;
the markets in which we participate involve a high number of competitors that is continuing to increase, and if we do not compete effectively, our operating results could be harmed;
we continue to expand our international operations, which exposes us to significant macroeconomic and other risks;

security breaches and improper access to, use of, or disclosure of our data or our clients’ data, or other cyber attacks on our systems, could result in litigation and regulatory risk, harm our reputation, our business or financial results;
we may acquire other companies, or technologies or be the target of strategic transactions, or be impacted by transactions by other companies, which could divert our management’s attention, result in additional dilution to our stockholders or use a significant amount of our cash resources and otherwise disrupt our operations and harm our operating results;
we sell our solution to larger organizations that require longer sales and implementation cycles and often demand more configuration and integration services or customized features and functions that we may not offer, any of which could delay or prevent these sales and harm our growth rates, business and operating results;
we rely on third-party telecommunications and internet service providers to provide our clients and their customers with telecommunication services and connectivity to our cloud contact center software and any failure by these service providers to provide reliable services could cause us to lose clients and subject us to claims for credits or damages, among other things;
we have a history of losses and we may be unable to achieve or sustain profitability;
our stock price has been volatile, may continue to be volatile and may decline, including due to factors beyond our control;
we may not be able to secure additional financing on favorable terms, or at all, to meet our future capital needs;
failure to comply with laws and regulations could harm our business and our reputation; and
we may not have sufficient cash to service our convertible senior notes and repay such notes, if required.
The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included in, or incorporated into, this report. If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may differ materially from what we anticipate. You should not place undue reliance on our forward-looking statements. Any forward-looking statements you read in this report reflect our views only as of the date of this report with respect to future events and are subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, growth strategy and liquidity. We undertake no obligation to update any forward-looking statements made in this report to reflect events or circumstances after the date of this report or to reflect new information or the occurrence of unanticipated events, except as required by law.

FIVE9, INC.
Notes to Condensed Consolidated Financial Statements (Unaudited)
1. Description of Business and Summary of Significant Accounting Policies
Five9, Inc. and its wholly-owned subsidiaries (the “Company”) is a provider of cloud software for contact centers. The Company was incorporated in Delaware in 2001 and is headquartered in San Ramon, California. The Company has offices in Europe, Asia and Australia, which primarily provide research, development, sales, marketing, and client support services.
Basis of Presentation
The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“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 financial statements prepared in accordance with 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, 2023. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates
The preparation of condensed consolidated financial statements in accordance with 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The significant estimates made by management affect revenue and related reserves, as well as the fair value of assets acquired and liabilities assumed through business combinations and the fair value of performance-based restricted stock units ("PRSUs"). Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates.
Significant Accounting Policies
There have been no material changes from the significant accounting policies previously disclosed in Part II, Item 8, of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 as filed with the SEC on February 22, 2024.
Recent Accounting Pronouncements Not Yet Effective
In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ ASU”) No. 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. This ASU is effective for the Company’s fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company is currently evaluating the impact of this ASU on its consolidated financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires disclosure of specific categories in the effective tax rate reconciliation and additional information on income taxes paid. This ASU is effective for the Company’s fiscal years beginning after December 15, 2024. Early adoption is permitted and may be adopted on a prospective or retrospective basis. The Company is currently evaluating the impact of this ASU on its consolidated financial statement disclosures.

Non-current149,885 136,571 
Total deferred contract acquisition costs, net$222,419 $198,282 
Contract assets and contract liabilities:
Contract assets (included in prepaid expenses and other current assets)$6,497 $4,106 
Contract liabilities (deferred revenue) (80,000)(68,187)
Noncurrent contract liabilities (deferred revenue) (included in other long-term liabilities)(627)(1,350)
Net contract liabilities$(74,130)$(65,431)
The Company receives payments from customers based upon billing cycles. Invoice payment terms are usually 30 days or less. Accounts receivable are recorded when the right to consideration becomes unconditional.
Deferred contract acquisition costs are recorded when incurred and are amortized over an estimated customer benefit period of five years.
The Company’s contract assets consist of unbilled amounts typically resulting from professional services revenue recognition when it exceeds the total amounts billed to the customer. The Company’s contract liabilities consist of advance payments and billings in excess of revenue recognized.
In the three and nine months ended September 30, 2024, the Company recognized revenue of $5.6 million and $52.3 million, respectively, related to its contract liabilities at December 31, 2023.
Remaining Performance Obligations
As of September 30, 2024, the aggregate amount of the total transaction price allocated in contracts with original duration of greater than one year to the remaining performance obligations was $1,100.4 million. The Company expects to recognize revenue on approximately three-fourths of the remaining performance obligations over the next 24 months, with the balance recognized thereafter. The Company excludes amounts for remaining performance obligations that are part of contracts with an original expected duration of one year or less. Such remaining performance obligations represent unsatisfied or partially unsatisfied performance obligations.
3. Investments and Fair Value Measurements
Marketable Investments
The Company’s marketable investments have been classified and accounted for as available-for-sale. The Company’s intent is that all marketable investments are available for use in its current operations, including marketable investments with maturity dates greater than one year from September 30, 2024. The Company’s

Fair Value Measurements
12

The Company carries cash equivalents and marketable investments at fair value. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
Level 1 — Observable inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 — Observable inputs other than Level 1 inputs, such as quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 — Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques.
The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments.
Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. The Company performs routine procedures such as comparing prices obtained from independent sources to ensure that appropriate fair values are recorded.

In March 2024, the Company issued $747.5 million aggregate principal amount of 1.00% convertible senior notes due 2029 (the "2029 convertible senior notes") in a private offering. In connection with the issuance of the 2029 convertible senior notes, the Company used part of the net proceeds from the issuance to repurchase approximately $313.1 million aggregate principal amount of its 0.50% convertible senior notes due 2025 (the "2025 convertible senior notes"). As of September 30, 2024 and December 31, 2023, the estimated fair value of the Company's outstanding 2025 convertible senior notes was $419.4 million and $718.3 million, respectively. As of September 30, 2024, the estimated fair value of the Company's outstanding 2029 convertible senior notes was $628.0 million. The fair values were determined based on the quoted price of the convertible senior notes in an inactive market on the last trading day of the reporting period and have been classified as Level 2 in the fair value hierarchy. See Note 6 for further information on the Company’s convertible senior notes.
In February 2022, the Company made a $2.0 million equity investment in a privately-held company that the Company does not have the ability to exercise significant influence over. The Company elected to utilize the measurement alternative for an equity security without a readily determinable fair value. Accordingly, this investment is accounted for at its cost minus impairment, if any, and is classified within Level 3. If the Company identifies observable price changes in orderly transactions for such investment or a similar investment, it will measure the investment at fair value as of the date that the observable transactions or events occurred. During the third quarter of 2024, the Company noted an indicator of impairment of this investment and recorded a $1.3 million impairment charge.
Except for the equity investment described above, there were no assets or liabilities measured at fair value on a non-recurring basis as of September 30, 2024 and December 31, 2023.
The fair value of the Company’s other financial instruments, including accounts receivable, accounts payable and other current liabilities, approximate their carrying value due to the relatively short maturity of those instruments. The carrying amounts of the Company’s operating and finance leases approximate their fair value, which is the present value of expected future cash payments based on assumptions about current interest rates and the creditworthiness of the Company.

6. Debt
Repurchase Transaction
In connection with the issuance of the 2029 convertible senior notes on March 1, 2024, the Company used part of the net proceeds from the issuance to repurchase approximately $313.1 million aggregate principal amount of
17

the outstanding 2025 convertible senior notes in privately-negotiated transactions for aggregate cash consideration of approximately $304.9 million (the “Repurchase Transaction”).
The Repurchase Transaction was accounted for as a debt extinguishment. The difference between the consideration used to extinguish the 2025 convertible senior notes and the carrying value of the 2025 convertible senior notes (including unamortized debt discount and issuance costs) resulted in an extinguishment gain of approximately $6.6 million recorded through Other income (expense), net on the Company’s condensed consolidated statements of operations and comprehensive loss.
In connection with the Repurchase Transaction, the Company also entered into a partial termination agreement with each bank counterparty and unwound a corresponding portion of the previously purchased capped call instruments entered into in connection with the issuance of the 2025 convertible senior notes (the “2025 Capped Calls”). The Company received approximately $0.5 million in cash in connection with these partial terminations, representing the fair value at the date of settlement of the unwound 2025 Capped Calls.
2029 Convertible Senior Notes and Related Capped Call Transactions
In March 2024, the Company issued $747.5 million aggregate principal amount of 2029 convertible senior notes in a private offering, which aggregate principal amount included the exercise in full of the initial purchasers’ option to purchase up to an additional $97.5 million principal amount of the 2029 convertible senior notes. The 2029 convertible senior notes mature on March 15, 2029 and bear interest at a fixed rate of 1.00% per annum, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2024. The total net proceeds from the issuance of the 2029 convertible senior notes, after deducting initial purchasers' discounts and commissions and estimated debt issuance costs, were approximately $728.8 million.
Each $1,000 principal amount of the 2029 convertible senior notes is initially convertible into 12.5918 shares of the Company’s common stock (the “2029 Conversion Option”), which is equivalent to an initial conversion price of approximately $79.42 per share of common stock, subject to adjustment upon the occurrence of specified events. The initial conversion price represents a premium of approximately 30% to the $61.09 per share closing price of the Company’s common stock on The Nasdaq Global Market on February 27, 2024. There have been no changes to the initial conversion price of the 2029 convertible senior notes since issuance. The 2029 convertible senior notes are convertible, in multiples of $1,000 principal amount, at the option of the holders prior to the close of business on the business day immediately preceding December 15, 2028, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2024 (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; (2) during the five business day period after any five consecutive trading day period (the “2029 Measurement Period”) in which the trading price (as defined in the 2029 Indenture governing the 2029 convertible senior notes) per $1,000 principal amount of the 2029 convertible senior notes for each trading day of the 2029 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 in effect on each such trading day; (3) if the Company calls any or all of the 2029 convertible senior notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after December 15, 2028 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 2029 convertible senior notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.
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 the Company’s common stock, at the Company’s election. If the Company undergoes a fundamental change (as defined in the indenture governing the 2029 convertible senior notes), subject to certain conditions, holders may require the Company to repurchase for cash all or any portion of their 2029 convertible senior notes, in principal amounts of $1,000 or a multiple thereof, at a fundamental change repurchase price equal to 100% of the principal amount of the 2029 convertible senior notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events or if the Company issues a notice of redemption, it will, under certain circumstances, increase the conversion rate for holders who elect to convert their notes in connection with such corporate event or during the relevant redemption period.
The closing market price of the Company's common stock of $28.73 per share on September 30, 2024, the last trading day during the three months ended September 30, 2024, was below $103.24 per share, which represents 130% of the initial conversion price of $79.42 per share. Additionally, 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, September 30, 2024, was not greater than or equal to 130% of
18

the initial conversion price. As such, during the three months ended September 30, 2024, the conditions allowing holders of the 2029 convertible senior notes to convert were not met. The 2029 convertible senior notes are therefore not convertible during the three months ending December 31, 2024.
The Company may not redeem the 2029 convertible senior notes prior to March 22, 2027. The Company may redeem for cash all or any portion of the 2029 convertible senior notes, at its option, on or after March 22, 2027 and prior to December 15, 2028, if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such 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 2029 convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. However, the Company may not redeem less than all of the outstanding 2029 convertible senior notes unless at least $100.0 million aggregate principal amount of 2029 convertible senior notes are outstanding and not called for redemption at the time the redemption notice is sent. No sinking fund is provided for the 2029 convertible senior notes.
The 2029 convertible senior notes are the Company’s senior unsecured obligations and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 2029 convertible senior notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated (including the 2025 convertible senior 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 indebtedness and other liabilities.
The net carrying amount of the 2029 convertible senior notes as of September 30, 2024 was as follows (in thousands):
September 30, 2024
Principal$747,500 
Unamortized issuance costs(16,568)

Contractual interest expense$1,869 $4,360

Total interest expense$2,789 $6,450 
The debt issuance costs are amortized into interest expense over the term of the 2029 convertible senior notes at an effective interest rate of 1.49%.
In connection with the issuance of the 2029 convertible senior notes, the Company entered into privately negotiated capped call transactions (each a “2029 Capped Call,” and collectively the "2029 Capped Calls") with certain financial institutions. The 2029 Capped Call has an initial strike price of approximately $79.42, subject to certain adjustments, which corresponds to the initial conversion price of the 2029 convertible senior notes. The 2029 Capped Calls have an initial cap price of $122.18 per share, subject to certain adjustments. The 2029 Capped Calls are expected to partially offset the potential dilution to the Company’s common stock upon any conversion of the 2029 convertible senior notes, with such offset subject to a cap based on the cap price. Each 2029 Capped Call covers, subject to anti-dilution adjustments, approximately 9.4 million shares of the Company’s common stock. The 2029 Capped Call is subject to adjustment upon the occurrence of specified extraordinary events affecting the Company, including merger events, tender offers, and announcement events. In addition, each 2029 Capped Call is subject to certain specified additional disruption events that may give rise to a termination of the 2029 Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings, and hedging disruptions. For accounting purposes, each 2029 Capped Call is treated as a separate transaction from, and not part of the terms of the 2029 convertible senior notes. As these transactions meet certain accounting criteria, the 2029 Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The 2029 Capped Calls will not be remeasured as long as they continue to meet the conditions for equity classification.

2025 Convertible Senior Notes and Related Capped Call Transactions
In May and June 2020, the Company issued $747.5 million aggregate principal amount of 2025 convertible senior notes in a private offering, which aggregate principal amount included the exercise in full of the initial purchasers’ option to purchase up to an additional $97.5 million principal amount of the 2025 convertible senior notes. The 2025 convertible senior notes mature on June 1, 2025 and bear interest at a fixed rate of 0.500% per annum, payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. The total net proceeds from the issuance of the 2025 convertible senior notes, after deducting initial purchasers' discounts and commissions and estimated debt issuance costs, were approximately $728.8 million.
In March 2024, the Company used part of the net proceeds from the issuance of the 2029 convertible senior notes to repurchase $313.1 million aggregate principal amount of the 2025 convertible senior notes in privately-negotiated transactions. As of September 30, 2024, after giving effect to the Repurchase Transaction, approximately $434.4 million aggregate principal amount of 2025 convertible senior notes remained outstanding.
Each $1,000 principal amount of the 2025 convertible senior notes is initially convertible into 7.4437 shares of the Company’s common stock (the “2025 Conversion Option”), which is equivalent to an initial conversion price of approximately $134.34 per share of common stock, subject to adjustment upon the occurrence of specified events. The initial conversion price represents a premium of approximately 30% to the $103.34 per share closing price of the Company’s common stock on The Nasdaq Global Market on May 21, 2020. There have been no changes to the initial conversion price of the 2025 convertible senior notes since issuance. The 2025 convertible senior notes are convertible, in multiples of $1,000 principal amount, at the option of the holders prior to the close of business on the business day immediately preceding March 1, 2025, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 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; (2) during the five business day period after any five consecutive trading day period (the “2025 Measurement Period”) in which the trading price (as defined in the 2025 Indenture governing the 2025 convertible senior notes) per $1,000 principal amount of the 2025 convertible senior notes for each trading day of the 2025 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 in effect on each such trading day; (3) if the Company calls any or all of the 2025 convertible senior notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after March 1, 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 2025 convertible senior notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. 
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 the Company’s common stock, at the Company’s election. If the Company undergoes a fundamental change (as defined in the indenture governing the 2025 convertible senior notes), subject to certain conditions, holders may require the Company to repurchase for cash all or any portion of their 2025 convertible senior notes, in principal amounts of $1,000 or a multiple thereof, at a fundamental change repurchase price equal to 100% of the principal amount of the 2025 convertible senior notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events or if the Company issues a notice of redemption, it will, under certain circumstances, increase the conversion rate for holders who elect to convert their notes in connection with such corporate event or during the relevant redemption period.
The closing market price of the Company's common stock of $28.73 per share on September 30, 2024, the last trading day during the three months ended September 30, 2024, was below $174.64 per share, which represents 130% of the initial conversion price of $134.34 per share. Additionally, 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, September 30, 2024, was not greater than or equal to 130% of the initial conversion price. As such, during the three months ended September 30, 2024, the conditions allowing holders of the 2025 convertible senior notes to convert were not met. The 2025 convertible senior notes are therefore not convertible during the three months ending December 31, 2024.
The 2025 convertible senior notes became redeemable at the Company's option on June 6, 2023. The Company may redeem for cash all or any portion of the 2025 convertible senior notes, at its option, prior to March 1, 2025, if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending not more than two trading days 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 2025
20

convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the 2025 convertible senior notes. During the three months ended September 30, 2024, the conditions allowing the Company to redeem for cash all or any portion of the 2025 convertible senior notes were not met.
The 2025 convertible senior notes are the Company’s senior unsecured obligations and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 2025 convertible senior notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; 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 indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

In connection with the issuance of the 2025 convertible senior notes, the Company entered into privately negotiated capped call transactions (each a “2025 Capped Call,” and collectively the "2025 Capped Calls") with certain financial institutions. The 2025 Capped Calls each have an initial strike price of approximately $134.34, which corresponds to the initial conversion price of the 2025 convertible senior notes. The initial cap price of the 2025 Capped Calls was $206.68 per share and is subject to certain adjustments under the terms of the 2025 Capped Calls. In connection with the Repurchase Transaction, the Company unwound a portion of the 2025 Capped Calls. Refer to the Repurchase Transaction section above for further information. There are no changes or amendments made to the remaining 2025 Capped Calls. The remaining 2025 Capped Calls cover, subject to anti-dilution adjustments, approximately 3.2 million shares of the Company’s common stock. Each 2025 Capped Call is subject to adjustment upon the occurrence of specified extraordinary events affecting the Company, including merger events, tender offers, and announcement events. In addition, each 2025 Capped Call is subject to certain specified additional disruption events that may give rise to a termination of each 2025 Capped Call, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings, and hedging disruptions. For accounting purposes, each 2025 Capped Call is a separate transaction from, and not part of the terms of the 2025 convertible senior notes.

PRSUs with Market and Service Conditions In 2022, the Company granted 284,282 PRSUs subject to market and service conditions (“market-based PRSUs”) with a grant date fair value of $30.6 million as part of its annual grant of equity incentive awards to certain executives and in connection with the appointment of Michael Burkland as its new Chief Executive Officer. In 2023, the Company granted 35,921 market-based PRSUs with a grant date fair value of $3.1 million. During the nine months ended September 30, 2024, the Company granted an additional
22

159,016 market-based PRSUs with a grant date fair value of $9.6 million. The amount that may be earned pursuant to the market-based PRSUs ranges from 0% to 200% of the target number based on the Company’s relative total shareholder return (“RTSR”) performance as compared to the companies in the S&P Software and Services Select Index during three one-year performance periods. One-third of the total market-based PRSUs may be earned and settled in shares following the end of each performance period based on RTSR performance and subject to continued employment through the payment date. If the Company’s absolute total shareholder return for any performance period is negative, then no more than 100% of the target amount of market-based PRSUs for such period may be earned. If an executive's employment with the Company terminates before the end of the final one-year performance period due to death or disability, 100% (if due to death) or 50% (if due to disability) of the unvested market-based PRSUs may be earned subject to ultimate RTSR performance in each remaining performance period. Upon a qualifying termination of employment in connection with a change in control of the Company, the unvested market-based PRSUs will vest on a double-trigger basis (i) at the target level for the market-based PRSUs subject to the 2022-2024 performance period, (ii) for the market-based PRSUs subject to the 2023-2025 performance period, and (iii) for the market-based PRSUs subject to the 2024-2026 performance period, (a) at the target level for the uncompleted portions of the performance periods and (b) at the actual level of performance measured through the date of the change in control of the Company, based on the price per share paid in such change in control. The fair value of the market-based PRSUs is determined on their grant date using a Monte Carlo Simulation model based upon assumptions presented below. The Company recognizes the fair value of the market-based PRSUs ratably over their requisite service period.
During the first quarter of 2023, the Company certified the performance results for the 2022 measurement period for the market-based PRSUs subject to the 2022-2024 performance period. Under the market-based PRSU agreements, the TSR payout percentage ranges from 0% to 200%, with a 50% payout at the 25th TSR percentile (threshold), 100% payout at the 55th TSR percentile (target), 200% payout at the 90th percentile or greater (maximum) and no payout below the threshold performance level. The Company determined that its actual total shareholder return was -52.64% for 2022, and that its relative total shareholder return ranking was in the 30.2 percentile relative to companies in the S&P Software & Services Select Index, which resulted in a payout percentage of 58.7% of target. During the first quarter of 2024, the Company certified the performance results for the 2023 measurement period for the market-based PRSUs subject to the 2022-2024 performance period. The Company determined that its actual total shareholder return was 19.95% for 2023, and that its relative total shareholder return ranking was in the 53.8 percentile relative to companies in the S&P Software & Services Select Index, which resulted in a payout percentage of 98.0% of target. During the first quarter of 2024, the Company also certified the performance results for the 2023 measurement period for the market-based PRSUs subject to the 2023-2025 performance period. The Company determined that its actual total shareholder return was 19.95% for 2023, and that its relative total shareholder return ranking was in the 50.5 percentile relative to companies in the S&P Software & Services Select Index, which resulted in a payout percentage of 92.5% of target.
PRSUs with Revenue and Service Conditions In 2022, the Company granted 66,167 PRSUs subject to revenue-based performance and service conditions (“revenue-based PRSUs”) with a grant date fair value of $6.6 million. The amount of revenue-based PRSUs that may be earned will be determined based on achievement of two quarterly revenue goals. One third of the revenue-based PRSUs may be earned based on achievement of the first revenue target and, if achieved, will vest in four quarterly installments, with the first installment occurring on the date such achievement is certified, subject to the executive's continuous service through the applicable vesting dates. Two thirds of the revenue-based PRSUs may be earned based on achievement of the second revenue target and, if achieved, will vest in eight quarterly installments, with the first installment occurring on the date such achievement is certified, subject to the executive's continuous service through the applicable vesting dates. The revenue-based PRSUs are otherwise on the Company's standard award terms for its market-based PRSUs. During 2023, the Company certified that the first revenue target was achieved, and thus recognized the related stock-based compensation expense for this first revenue target. However, the Company certified during the first quarter of 2024
23

that, as of December 31, 2023, the second revenue target was not achieved, and thus did not recognize the related stock-based compensation expense and cancelled the shares associated with this target.

8. Net Loss Per Share
Basic net loss per share is calculated by dividing net loss by the weighted average number of shares of common stock outstanding during the period, and excludes any dilutive effects of employee stock-based awards and potential shares upon conversion of the convertible senior notes. Diluted net loss per share is computed giving effect to all potentially dilutive shares of common stock, including common stock issuable upon exercise of stock options, vesting of RSUs and PRSUs, and shares of common stock issuable upon conversion of convertible senior notes. As the Company had net losses for the three and nine months ended September 30, 2024 and 2023, all potentially issuable shares of common stock were determined to be anti-dilutive.

The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):

The Company used the if-converted method for calculating any potential dilutive effect of its convertible senior notes for the three and nine months ended September 30, 2024 and 2023. Under this method, the Company calculates diluted earnings per share under both the cash and share settlement assumptions to determine which is more dilutive. If share settlement is more dilutive, the Company calculates diluted earnings per share assuming that all of the convertible senior notes were converted solely into shares of common stock at the beginning of the reporting period. The potential impact upon the conversion of the convertible senior notes were excluded from the calculation of diluted net loss per share for the three and nine months ended September 30, 2024 and 2023 because the effect would have been anti-dilutive.
9. Income Taxes
The (benefit from) provision for income taxes for the three and nine months ended September 30, 2024 was approximately $(3.9) million and $0.5 million, respectively. The provision for income taxes for the three and nine months ended September 30, 2023 was approximately $0.9 million and $2.2 million, respectively.

The benefit from income taxes for the three months ended September 30, 2024 was primarily related to the Company's acquisition of Acqueon, which included a domestic net deferred tax liability balance of $4.8 million and provided the Company with a source of taxable income to release a portion of its U.S.valuation allowance. The provision for income taxes for the nine months ended September 30, 2024 consisted primarily of U.S. federal and U.S. state tax expense as a result of IRC Section 174 research and experimental capitalization requirements and tax attribute utilization limitations, and foreign current income tax expense as a result from income produced by the Company's intercompany cost-plus operating model, which were partially offset by the benefit related to the Company's acquisition of Acqueon, discussed above. The provision for income taxes for the three and nine months ended September 30, 2023 consisted primarily of current U.S. state tax expense due to the lack of available net operating losses to offset the taxable income generated and foreign income tax expense due to the Company's intercompany cost-plus operating model.
For the three and nine months ended September 30, 2024, the (benefit from) provision for income taxes differed from the statutory amount primarily due to the domestic full valuation allowance position maintained against the domestic net deferred tax assets, and the partial release discussed above. For the three and nine months ended September 30, 2023, the provision for income taxes differed from the statutory amount primarily due to domestic state income taxes, foreign income taxes and the Company realizing no benefit for prior year domestic losses due to maintaining a full valuation allowance against its domestic net deferred tax assets.
The realization of tax benefits from deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, to be recognized in the periods the items are expected to be deductible or taxable. Based on the weight of the available objective evidence, the Company does not believe it is more likely than not that the U.S. net deferred tax assets will be realizable. Accordingly, the Company has provided a full valuation allowance against
25

such net deferred tax assets as of September 30, 2024 and December 31, 2023. The Company intends to maintain the valuation allowance until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance. During the three and nine months ended September 30, 2024, there were no material changes to the total amount of unrecognized tax benefits.
10. Commitments and Contingencies
Commitments
The Company’s principal commitments consist of future payment obligations under its convertible senior notes, finance leases to finance data centers and other computer and networking equipment, operating leases for office facilities, cloud services and software and maintenance agreements, and agreements with third parties to provide co-location hosting and telecommunication services. These commitments as of December 31, 2023 are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, and material updates to these commitments during the nine months ended September 30, 2024 are disclosed herein, including in this Note 10 and in Note 12.
As of September 30, 2024, the Company’s commitments under various co-location hosting and telecommunications agreements totaled $11.7 million for terms ranging up to 58 months. These agreements require the Company to make monthly payments over the service term in exchange for certain network services.
As of September 30, 2024, the Company had outstanding cloud services and software and maintenance agreement commitments totaling $42.1 million, of which $0.4 million is expected to be purchased in the remainder of 2024, $21.9 million is expected to be purchased in 2025, and the remaining $19.8 million is expected to be purchased in 2026. During the three months ended September 30, 2024, the Company entered into equipment finance lease arrangements that resulted in a $17.2 million additional reduction of its outstanding cloud services commitment. See Note 12 for more information.
As of September 30, 2024, (i) $434.4 million of aggregate principal of the 2025 convertible senior notes was outstanding and is due on June 1, 2025, and (ii) $747.5 million of aggregate principal of the 2029 convertible senior notes was outstanding and is due on March 15, 2029. See Note 6 for more information concerning the convertible senior notes.
Legal Matters
The Company is involved in various legal and regulatory matters arising in the normal course of business. In management’s opinion, resolution of these matters is not expected to have a material impact on the Company’s consolidated results of operations, cash flows, or its financial position. However, due to the uncertain nature of legal matters, an unfavorable resolution of a matter could materially affect the Company’s future consolidated results of operations, cash flows or financial position in a particular period. The Company expenses legal fees as incurred.
Indemnification Agreements
In the ordinary course of business, the Company enters into agreements of varying scope and terms pursuant to which it agrees to indemnify clients, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, including breach of security, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with its directors, officers and certain employees that requires it, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. There are no claims that the Company is aware of that could have a material effect on the consolidated balance sheets, consolidated statements of operations and comprehensive loss, or consolidated statements of cash flows.

12. Leases
The Company has leases for offices, data centers and computer and networking equipment that expire at various dates through 2031. The Company’s leases have remaining terms of one to seven years, some of the leases include a Company option to extend the leases for up to one to five years, and some of the leases include the option to terminate the leases upon 30-days' notice. The Company does not separate lease and non-lease components for real estate operating leases. The Company entered into three-year equipment finance lease agreements and recognized $18.6 million right of use assets during the three months ended September 30, 2024, which were reported within "Finance lease right-of-use assets" and are being depreciated on a straight-line basis over the lease term. As a result, the Company also recognized short-term lease liabilities of $5.9 million within "Finance lease liabilities" and long-term lease liabilities of $12.7 million within "Finance lease liabilities - less current portion" for the three months ended September 30, 2024.

13. Acquisitions
Acqueon
On August 27, 2024, the Company acquired all of the issued and outstanding shares of capital stock of Acqueon for total consideration of approximately $173.8 million. This acquisition, which was accounted for as a business combination, is intended to build on the pre-existing partnership between the companies, and to extend the Company's AI-powered CX platform by adding omnichannel proactive customer engagement to expand Five9’s outbound capabilities.
The excess of the purchase price over identifiable intangible assets and net tangible assets in the amount of $138.2 million was allocated to goodwill, which is not deductible for tax purposes. The fair values assigned to assets acquired and liabilities assumed are based on management’s best estimates and assumptions as of the acquisition date and are considered preliminary pending finalization of valuation analyses pertaining to intangible assets acquired, liabilities assumed and tax liabilities assumed. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. The following table presents the preliminary allocation of the purchase price at the acquisition date (in thousands):

         Total$173,827 
The acquired technology, customer relationships, and trademarks will be amortized on a straight-line basis over their estimated useful lives of eight years, five years, and three years, respectively. The Company used the income approach to estimate the fair value of intangible assets acquired.
In connection with this acquisition, the Company incurred total acquisition-related transaction costs of $2.0 million and $5.3 million during the three and nine months ended September 30, 2024, respectively, which have been expensed as incurred and included in general and administrative expenses in the consolidated statements of operations and comprehensive loss.
The results of operations of this acquisition are included in the accompanying consolidated statements of operations and comprehensive loss from the date of acquisition and are not material to the Company's condensed consolidated financial statements.

Aceyus
On August 14, 2023, the Company acquired all of the issued and outstanding shares of capital stock of Aceyus, Inc. ("Aceyus") for total cash consideration of approximately $82.0 million. This acquisition, which was accounted for as a business combination, is intended to accelerate the Company's ability to capitalize on two business opportunities, namely facilitating the migration of large enterprise customers from on-premise to cloud and leveraging contextual data to deliver personalized experiences throughout the customer journey, including using this contextual data in the Company's AI & Automation solutions.
The excess of the purchase price over identifiable intangible assets and net tangible assets in the amount of $61.8 million was allocated to goodwill, which is not deductible for tax purposes. The fair values assigned to assets acquired and liabilities assumed are based on management’s best estimates and assumptions as of the reporting date and are considered final. The Company recorded an adjustment of $0.1 million during the one year from acquisition date measurement period. The following table presents the final allocation of the purchase price at the acquisition date (in thousands):

In connection with this acquisition, the Company incurred total acquisition-related transaction costs of $2.2 million in 2023, and incurred no additional costs during the nine months ended September 30, 2024, which have been expensed as incurred and included in general and administrative expenses in the consolidated statements of operations and comprehensive loss.
The results of operations of this acquisition are included in the accompanying consolidated statements of operations and comprehensive loss from the date of acquisition and are not material to the Company's condensed consolidated financial statements.
14. Restructuring

On August 20, 2024, the Company announced a reduction in force plan (“Plan”) as part of its broader efforts to drive balanced, profitable growth, further supporting its positive, long-term outlook and focus on increasing shareholder value. The Plan reduced the Company’s global full-time employees by approximately 6%. For the three months ended September 30, 2024, the Company incurred a total of $9.6 million in restructuring costs under the Plan, primarily consisting of notice period payments, severance payments, employee benefits and related costs, all of which are cash expenditures, of which $2.1 million was recorded in cost of revenue, $1.9 million was recorded in research and development expenses, $4.4 million was recorded in sales and marketing expenses, and $1.2 million was recorded in general and administrative expenses. As of September 30, 2024, $3.0 million had been paid and the remaining $6.6 million was recorded within "Accrued and other current liabilities" and is mostly expected to be paid by the fourth quarter of 2024. The Company does not expect to incur any additional costs under this plan.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
You should read the following discussion in conjunction with the condensed consolidated financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2023.
Overview
We are a pioneer and leading provider of intelligent cloud contact centers with more than 3,000 clients. We believe we achieved this leadership position through our expertise and technology, which has empowered us to help organizations of all sizes transition from legacy on-premise contact center systems to our cloud solution. Our solution, comprised of our Virtual Contact Center, or VCC, cloud platform and applications, allows simultaneous management and optimization of customer interactions across voice, chat, email, web, social media and mobile channels, either directly or through our application programming interfaces, or APIs. Our VCC cloud platform matches each customer interaction with an appropriate agent resource and delivers relevant customer data to the agent in real-time through integrations with adjacent enterprise applications, such as customer relationship management, or CRM, software, to optimize the customer experience and improve agent productivity. Unlike legacy on-premise contact center systems, our solution requires minimal up-front investment, can be rapidly deployed and adjusted depending on our client’s requirements.
Since founding our business in 2001, we have focused exclusively on delivering cloud contact center software. We initially targeted smaller contact center opportunities with our telesales team and, over time, invested in expanding the breadth and depth of the functionality of our cloud platform to meet the evolving requirements of our clients. In 2009, we made a strategic decision to expand our market opportunity to include larger contact centers. This decision drove further investments in research and development and the establishment of our field sales team to meet the requirements of these larger contact centers. We believe this shift has helped us diversify our client base, while significantly enhancing our opportunity for future revenue growth. To complement these efforts, we have also focused on building client awareness and driving adoption of our solution through marketing activities, which include internet advertising, digital marketing campaigns, social media, trade shows, industry events, telemarketing and out of home campaigns.
We provide our solution through a SaaS business model with recurring subscriptions. We offer a comprehensive suite of applications delivered on our VCC cloud platform that are designed to enable our clients to manage and optimize interactions across inbound and outbound contact centers. We primarily generate revenue by selling subscriptions and related usage of our VCC cloud platform. We charge our clients monthly subscription fees for access to our solution, primarily based on the number of agent seats, as well as the specific functionalities and applications our clients deploy. We define agent seats as the maximum number of named agents allowed to concurrently access our solution. Our clients typically have more named agents than agent seats, and multiple named agents may use an agent seat, though not simultaneously. Substantially all of our clients purchase both subscriptions and related telephony usage from us. A small percentage of our clients subscribe to our platform but purchase telephony usage directly from wholesale telecommunications service providers. We do not sell telephony usage on a stand-alone basis to any client. The related usage fees are based on the volume of minutes for inbound and outbound interactions. We also offer bundled plans, generally for smaller deployments, where the client is charged a single monthly fixed fee per agent seat that includes both subscription and unlimited usage in the contiguous 48 states and, in some cases, Canada. We offer monthly, annual and multiple-year contracts to our clients, generally with 30 days’ notice required for reductions in the number of agent seats. Increases in the number of agent seats can be provisioned almost immediately. Our clients, therefore, are able to adjust the number of agent seats used to meet their changing contact center volume needs. Our larger clients typically choose annual contracts, which generally include an implementation and ramp period of several months. Fixed subscription fees, including bundled plans, are generally billed monthly in advance, while related usage fees are billed in arrears. For each of the three and nine months ended September 30, 2024, subscription and related usage fees accounted for 92% of our revenue. For each of the three and nine months ended September 30, 2023, subscription and related usage fees accounted for 92% of our revenue. The remainder was comprised of professional services revenue from the implementation and optimization of our solution.
Macroeconomic and Other Factors
We are subject to risks and exposures, including those caused by adverse economic conditions, including continued macroeconomic challenges, the Russia-Ukraine conflict and the conflict in the Middle East.
Macroeconomic factors include the global economic slowdown, continued inflation, increased interest rates, supply chain disruptions, decreased economic output and fluctuations in currency exchange rates. We continuously
32

monitor the direct and indirect impacts of these circumstances on our business and financial results, as well as the overall global economy and geopolitical landscape. While the implications of macroeconomic events on our business, results of operations and overall financial position remain uncertain over the long term, we expect that adverse economic conditions will continue to have an adverse impact on our revenue in future periods. For example, our installed base business, which typically contributes approximately half of our annual revenue growth, continues to experience macroeconomic headwinds.
In August 2024, we announced a Plan as part of our broader efforts to drive balanced, profitable growth, further supporting our positive, long-term outlook and focus on increasing shareholder value. The Plan reduced our global full-time employees by approximately 6%. For the three months ended September 30, 2024, we incurred a total of $9.6 million in restructuring costs under the Plan, primarily consisting of notice period payments, severance payments, employee benefits and related costs, all of which are cash expenditures, of which $2.1 million was recorded in cost of revenue, $1.9 million was recorded in research and development expenses, $4.4 million was recorded in sales and marketing expenses, and $1.2 million was recorded in general and administrative expenses. As of September 30, 2024, $3.0 million had been paid and the remaining $6.6 million was recorded within accrued and other current liabilities and is mostly expected to be paid in the fourth quarter of 2024. We do not expect to incur any additional costs under this plan.
In March 2022 we decided to close our Russia office and to establish a new European development center in Portugal, in part due to the growing uncertainty arising from the Russia-Ukraine conflict. During both the three and nine months ended September 30, 2024, we incurred approximately $0.2 million in costs related to the closure and relocation of our Russian operations. During the three and nine months ended September 30, 2023, we incurred approximately $0.9 million and $2.7 million in costs related to the closure and relocation of our Russian operations. Going forward, we do not expect to incur additional material costs related to the closure and relocation of our Russia operations. We currently do not believe that this decision will have a material effect on our business, results of operations or financial condition.
Key GAAP Operating Results
Our revenue increased to $264.2 million and $763.3 million for the three and nine months ended September 30, 2024 from $230.1 million and $671.4 million for the three and nine months ended September 30, 2023. Revenue growth was primarily attributable to our larger clients, driven by an increase in our sales and marketing activities and our improved brand awareness. For each of the three and nine months ended September 30, 2024 and 2023, no single client accounted for more than 10% of our total revenue. As of September 30, 2024, we had over 3,000 clients across multiple industries with a wide range of seat sizes. We had a net loss of $4.5 million and $24.4 million in the three and nine months ended September 30, 2024, compared to a net loss of $20.4 million and $69.4 million in the three and nine months ended September 30, 2023.
We have continued to make significant expenditures and investments, including in sales and marketing, research and development, infrastructure and investments in complementary businesses, technologies and intellectual property rights. We primarily evaluate the success of our business based on revenue growth and the efficiency and effectiveness of our investments. The growth of our business and our future success depend on many factors, including our ability to continue to expand our base of larger clients, grow revenue from our existing clients, innovate and expand internationally. While these areas represent significant opportunities for us, they also pose risks and challenges that we must successfully address, including the impact of continued macroeconomic challenges, the Russia-Ukraine conflict and the conflict in the Middle East, in order to successfully grow our business and improve our operating results.
Key Operating and Non-GAAP Financial Performance Metrics
In addition to measures of financial performance presented in our condensed consolidated financial statements, we monitor the key metrics set forth below to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies.
Annual Dollar-Based Retention Rate
We believe that our Annual Dollar-Based Retention Rate provides insight into our ability to retain and grow revenue from our clients, and is a measure of the long-term value of our client relationships. Our Annual Dollar-Based Retention Rate is calculated by dividing our Retained Net Revenue by our Retention Base Net Revenue on a monthly basis, which we then average using the rates for the trailing twelve months for the period presented. We define Retention Base Net Revenue as recurring net revenue from all clients in the comparable prior year period, and
33

we define Retained Net Revenue as recurring net revenue from that same group of clients in the current period. We define recurring net revenue as net subscription and related usage revenue.
The following table shows our Annual Dollar-Based Retention Rate based on Net Revenue for the periods presented:
Twelve Months Ended
September 30, 2024September 30, 2023
Annual Dollar-Based Retention Rate108%110%
Our Dollar-Based Retention Rate decreased year-over-year primarily due to continued macroeconomic headwinds on our installed base.
Adjusted EBITDA
We monitor adjusted EBITDA, a non-GAAP financial measure, to analyze our financial results and believe that it is useful to investors, as a supplement to U.S. GAAP measures, in evaluating our ongoing operational performance and enhancing an overall understanding of our past financial performance. We believe that adjusted EBITDA helps illustrate underlying trends in our business that could otherwise be masked by the effect of the income or expenses that we exclude from adjusted EBITDA. Furthermore, we use this measure to establish budgets and operational goals for managing our business and evaluating our performance. We also believe that adjusted EBITDA provides an additional tool for investors to use in comparing our recurring core business operating results over multiple periods with other companies in our industry.
Adjusted EBITDA should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with U.S. GAAP, and our calculation of adjusted EBITDA may differ from that of other companies in our industry. We compensate for the inherent limitations associated with using adjusted EBITDA through disclosure of these limitations, presentation of our financial statements in accordance with U.S. GAAP and reconciliation of adjusted EBITDA to the most directly comparable U.S. GAAP measure, net loss. We calculate adjusted EBITDA as net loss before (1) depreciation and amortization, (2) stock-based compensation, (3) interest expense, (4) gain on early extinguishment of debt, (5) interest (income) and other, (6) exit costs related to the closure and relocation of Russian operations, (7) acquisition and related transaction costs and one-time integration costs, (8) lease amortization for finance leases, (9) costs related to a reduction in force plan, (10) (benefit from) provision for income taxes, and (11) other items that do not directly affect what we consider to be our core operating performance.

Key Components of Our Results of Operations
Revenue
Our revenue consists of subscription and related usage as well as professional services. We consider our subscription and related usage to be recurring revenue. This recurring revenue includes fixed subscription fees for the delivery and support of our VCC cloud platform, as well as related usage fees. The related usage fees are generally based on the volume of minutes for inbound and outbound client interactions. We also offer bundled plans, generally for smaller deployments, where the client is charged a single monthly fixed fee per agent seat that includes both subscription and unlimited usage in the contiguous 48 states and, in some cases, Canada. We offer monthly, annual and multiple-year contracts for our clients, generally with 30 days’ notice required for reductions in the number of agent seats. Increases in the number of agent seats can be provisioned almost immediately. Our clients, therefore, are able to adjust the number of agent seats used to meet their changing contact center volume needs. Our larger clients typically choose annual contracts, which generally include an implementation and ramp period of several months.
Fixed subscription fees, including plans with bundled usage, are generally billed monthly in advance, while variable usage fees are billed in arrears. Fixed subscription fees are recognized on a straight-line basis over the applicable term, which is predominantly the monthly contractual billing period. Support activities include technical assistance for our solution and upgrades and enhancements on a when and if available basis, which are not billed separately. Variable subscription related usage fees for non-bundled plans are billed in arrears based on client-
35

specific per minute rate plans and are recognized as actual usage occurs. We generally require advance deposits from clients based on estimated usage. All fees, except usage deposits, are non-refundable.
In addition, we generate professional services revenue from assisting clients in implementing our solution and optimizing use. These services include application configuration, system integration and education and training services. Professional services are primarily billed on a fixed-fee basis and are typically performed by us directly. In limited cases, our clients choose to perform these services themselves or engage their own third-party service providers to perform such services. Professional services are recognized as the services are performed using the proportional performance method, with performance measured based on labor hours, provided all other criteria for revenue recognition are met.
While the implications of macroeconomic events on our business, results of operations and overall financial position remain uncertain over the long term, we expect that macroeconomic challenges will continue to have an adverse impact on our revenue in future periods. For example, our installed base business, which typically contributes approximately half of our annual revenue growth, continues to experience macroeconomic headwinds.
Cost of Revenue
Our cost of revenue consists primarily of personnel costs, including stock-based compensation, fees that we pay to telecommunications providers for usage, Universal Service Fund, or USF, contributions and other regulatory costs, depreciation and related expenses of our servers and equipment, costs to build out and maintain co-location data centers, costs of public cloud-based data centers, allocated office and facility costs, amortization of acquired technology, amortization of internal-use software development costs and lease amortization for finance leases. Cost of revenue can fluctuate based on a number of factors, including the fees we pay to telecommunications providers, which vary depending on our clients’ usage of our VCC cloud platform, the timing of capital expenditures and related depreciation charges and changes in headcount. We expect to continue investing in professional services, public cloud, cloud operations, client support and network infrastructure to maintain high quality and availability of services, which we believe will result in absolute dollar increases in cost of revenue but percentage of revenue declines in the long-term through economies of scale.
Operating Expenses
We classify our operating expenses as research and development, sales and marketing, and general and administrative expenses.
Research and Development.    Our research and development expenses consist primarily of salary and related expenses, including stock-based compensation, for personnel related to the development of improvements and expanded features for our services, as well as quality assurance, testing, product management and allocated overhead. We expense research and development expenses as they are incurred except for internal use software development costs that qualify for capitalization. We believe that continued investment in our solution is important for our future growth, and we expect our research and development expenses to increase in absolute dollars and fluctuate as a percentage of revenue in the near and longer term.
Sales and Marketing.    Sales and marketing expenses consist primarily of salaries and related expenses, including stock-based compensation, for personnel in sales and marketing, amortization of deferred contract acquisition costs, as well as advertising, marketing, corporate communications, travel costs and allocated overhead. We believe it is important to continue investing in sales and marketing to continue to generate revenue growth, and we expect sales and marketing expenses to increase in absolute dollars and fluctuate as a percentage of revenue in the near and longer term as we continue to support our growth initiatives.
General and Administrative.    General and administrative expenses consist primarily of salary and related expenses, including stock-based compensation, for management, finance and accounting, legal, information systems and human resources personnel, professional fees, compliance costs, other corporate expenses and allocated overhead. We expect that general and administrative expenses will fluctuate in absolute dollars and as a percentage of revenue in the near term, but to increase in absolute dollars and decline as a percentage of revenue in the longer term.

The increase in interest expense for the three and nine months ended September 30, 2024 compared to the same periods of 2023 was primarily due to the issuance of the 2029 convertible senior notes in March 2024.
In connection with the issuance of the 2029 convertible senior notes, we used part of the net proceeds from the issuance to repurchase approximately $313.1 million aggregate principal amount of our then outstanding 2025 convertible senior notes in privately-negotiated transactions for aggregate cash consideration of approximately $304.9 million. The repurchase transaction was accounted for as a debt extinguishment. The difference between the consideration used to extinguish the 2025 convertible senior notes and the carrying value of the 2025 convertible senior notes (including unamortized debt discount and issuance cost) resulted in an extinguishment gain of approximately $6.6 million. See Note 6 to the condensed consolidated financial statements for further details.
The increase in interest income and other for the three and nine months ended September 30, 2024 compared to the same periods of 2023 was primarily due to higher interest income on our marketable investments due to higher investable balances and higher interest rates, offset in part by a $1.3 million impairment charge of an equity investment.
Liquidity and Capital Resources
To date, we have financed our operations primarily through sales of our solution, net proceeds from our equity and debt financings, including the issuance of our 2029 convertible senior notes in March 2024, issuance of our 2025 convertible senior notes in May and June 2020 and of our 2023 convertible senior notes in May 2018, and lease facilities. As of September 30, 2024, we had $554.0 million in working capital, which included $291.0 million in cash and cash equivalents and $675.7 million in marketable investments. Our intent is that all marketable investments are available for use in our current operations, including marketable investments with maturity dates greater than one year from September 30, 2024.
39

In March 2024, we issued $747.5 million aggregate principal amount of our 2029 convertible senior notes in a private offering. The 2029 convertible senior notes mature of March 15, 2029 and are our senior unsecured obligations. The 2029 convertible senior notes bear interest at a fixed rate of 1.00% per annum, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2024. The total net proceeds from the issuance of the 2029 convertible senior notes, after deducting initial purchaser' discounts and commissions and estimated debt issuance costs, were approximately $728.9 million. In connection with the issuance of the 2029 convertible senior notes, we used part of the net proceeds from the issuance to repurchase approximately $313.1 million aggregate principal amount of our then outstanding 2025 convertible senior notes in privately-negotiated transactions for aggregate cash consideration of approximately $304.9 million. In connection with the issuance of the 2029 convertible senior notes, we also entered into privately negotiated capped call transactions with certain financial institutions. We believe our existing cash and cash equivalents will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months. 
We plan to continue to finance our operations in the future primarily through sales of our solution, net proceeds from equity and debt financings, and lease facilities, but we may consider pursuing a revolving credit facility in the future. Our future capital requirements will depend on many factors including our growth rate, continuing market acceptance of our solution, the strength of the global economy, client retention, growth within our installed base, our ability to gain new clients, the timing and extent of spending to support research and development efforts, the outcome of any pending or future litigation or other claims by third parties or governmental entities, the expansion of sales and marketing activities and personnel, the introduction of new and enhanced offerings, expenses incurred in closing our Russia operations and expanding our operations in Portugal and any operational disruptions due to this transition, and the effect of the length and severity of the continued macroeconomic challenges, the Russia-Ukraine conflict, and the conflict in the Middle East on these or other factors. We may also acquire or invest in complementary businesses, technologies and intellectual property rights, such as our recent acquisitions of Aceyus in August 2023 and Acqueon in August 2024, which may increase our use of cash and future capital requirements, both to pay acquisition costs and to support our combined operations. We may raise additional capital through equity or debt financings at any time to fund these or other requirements. However, we may not be able to raise additional capital through equity or debt financings when needed on terms acceptable to us or at all, depending on our financial performance and condition, economic and market conditions, the trading price of our common stock, and other factors, including the length and severity of the current economic downturn and fluctuations in the financial markets, including due to the Russia-Ukraine conflict and the conflict in the Middle East. If we are unable to raise additional capital as needed, our business, operating results and financial condition could be harmed. In addition, if our operating performance during the next twelve months is below our expectations, our liquidity and ability to operate our business also could be harmed.
If we raise additional funds by issuing equity or equity-linked securities, the ownership of our existing stockholders would be diluted. If we raise additional funds through the incurrence of additional indebtedness, we will be subject to increased debt service obligations and could also be subject to restrictive covenants and other operating restrictions that could negatively impact our ability to operate our business.
Cash Flows
The following table summarizes our cash flows for the periods presented (in thousands):
Nine Months Ended
September 30, 2024September 30, 2023
Net cash provided by operating activities$93,353 $92,294 
Net cash used in investing activities(284,741)(234,974)
Net cash provided by financing activities339,398 91,047 
Net increase (decrease) in cash, cash equivalents and restricted cash$148,010 $(51,633)
Cash Flows from Operating Activities
Cash provided by operating activities is primarily influenced by our personnel-related expenditures, data center and telecommunications carrier costs, office and facility related costs, USF contributions and other regulatory costs and the amount and timing of client payments. If we continue to improve our financial results, we expect net cash provided by operating activities to increase. Our largest source of operating cash inflows is cash collections from our clients for subscription and related usage services. Payments from clients for these services are typically received monthly.
40

Net cash provided by operating activities was $93.4 million during the nine months ended September 30, 2024. Net cash provided by operating activities resulted from our net loss of $24.3 million, adjustments to reconcile net loss to net cash provided by operating activities of $207.2 million, primarily consisting of $127.9 million of stock-based compensation, $52.2 million of amortization of deferred contract acquisition costs, $38.3 million of depreciation and amortization, $10.6 million of amortization of operating lease right-of-use assets, $4.0 million of amortization of issuance costs on our convertible senior notes, $1.3 million impairment charge of an equity investment, $(16.8) million accretion of discount on marketable investments and $(6.6) million gain on early extinguishment of debt, partially offset by use of cash for operating assets and liabilities of $(89.5) million primarily due to the timing of cash payments to vendors and cash receipts from customers.

Critical Accounting Policies and Estimates
Our condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.
41

There have been no material changes to our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 22, 2024.

Contractual and Other Obligations
Our material cash requirements include the following contractual and other obligations.
Convertible Senior Notes
In May and June 2020, we issued $747.5 million aggregate principal amount of our 2025 convertible senior notes in a private offering. The 2025 convertible senior notes mature on June 1, 2025 and are our senior unsecured obligations. The 2025 convertible senior notes bear interest at a fixed rate of 0.50% per annum, payable semiannually in arrears on June 1 and December 1 of each year, beginning December 1, 2020. The total net proceeds from the offering, after deducting initial purchasers’ discounts and commissions and estimated debt issuance costs, were approximately $728.8 million. In connection with the issuance of the 2029 convertible senior notes, we used part of the net proceeds from the issuance to repurchase approximately $313.1 million aggregate principal amount of our 2025 convertible senior notes. As of September 30, 2024, the aggregate principal amount outstanding of our 2025 convertible senior notes was $434.4 million.
In March 2024, we issued $747.5 million aggregate principal amount of our 2029 convertible senior notes in a private offering. The 2029 convertible senior notes mature of March 15, 2029 and are our senior unsecured obligations. The 2029 convertible senior notes bear interest at a fixed rate of 1.00% per annum, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2024. The total net proceeds from the issuance of the 2029 convertible senior notes, after deducting initial purchasers' discounts and commissions and debt issuance costs, were approximately $728.9 million. As of September 30, 2024, the aggregate principal amount outstanding of our 2025 convertible senior notes was $747.5 million.
See Note 6 to the condensed consolidated financial statements included in this report for further details.
Leases
We have leases for offices, data centers and computer and networking equipment that expire at various dates through 2031. Our leases have remaining terms of one to seven years. Some of the leases include an option to extend the leases for up to one to five years, and some of the leases include the option to terminate the leases upon 30-days' notice. We had outstanding operating lease obligations of $56.9 million as of September 30, 2024, with $3.5 million payable in the remainder of 2024, $24.0 million payable in 2025 and 2026, $15.0 million payable in 2027 and 2028, and $14.4 million payable after 2028. We also had outstanding finance lease obligations of $23.1 million as of September 30, 2024, with $2.2 million payable in the remainder of 2024, $16.4 million payable in 2025 and 2026, and $4.5 million payable in 2027 and 2028. We entered into three-year equipment finance lease agreements and recognized $18.6 million right of use assets during the three months ended September 30, 2024, which were reported within "Finance lease right-of-use assets" and are being depreciated on a straight-line basis over the lease term. As a result, we also recognized short-term lease liabilities of $5.9 million within "Finance lease liabilities" and long-term lease liabilities of $12.7 million within "Finance lease liabilities - less current portion" for the three months ended September 30, 2024. See Note 12 to the condensed consolidated financial statements included in this report for further details.
Cloud Services and Software and Maintenance
As of September 30, 2024, we had outstanding cloud services and software and maintenance agreement commitments totaling $42.1 million, of which $0.4 million is expected to be purchased in the remainder of 2024, $21.9 million is expected to be purchased in 2025, and the remaining $19.8 million is expected to be purchased in 2026. During the three months ended September 30, 2024, we entered into equipment finance lease arrangements that resulted in a $17.2 million additional reduction of our outstanding cloud services commitment. See Note 12 for more information.
Hosting and Telecommunication Usage Services
42

We have agreements with third parties to provide co-location hosting and telecommunication usage services. The agreements require payments per month for a fixed period of time in exchange for certain guarantees of network and telecommunication availability. As of September 30, 2024, we had outstanding hosting and telecommunication usage services obligations of $11.7 million, with $1.5 million payable in the remainder of 2024, $7.4 million payable in 2025 and 2026, $2.7 million payable in 2027 and 2028, and $0.1 million payable in 2029.
Indemnification Agreements
In the ordinary course of business, we enter into agreements of varying scope and terms pursuant to which we agree to indemnify clients, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by us or from intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors, officers and certain employees that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. There are no claims that we are aware of that could have a material effect on our consolidated balance sheet, consolidated statements of operations and comprehensive loss, or consolidated statements of cash flows.
 Contingencies — Legal and Regulatory
We are subject to certain legal and regulatory proceedings, and from time to time may be involved in a variety of claims, lawsuits, investigations, and proceedings relating to contractual disputes, intellectual property rights, employment matters, regulatory compliance matters, and other litigation matters relating to various claims that arise in the normal course of business. We determine whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. We assess our potential liability by analyzing specific litigation and regulatory matters using reasonably available information. We develop our views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. Legal fees are expensed in the period in which they are incurred. See Note 10 to the condensed consolidated financial statements for more details.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risk in the ordinary course of our business. 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 a result of fluctuations in interest rates and foreign currency exchange rates. We do not hold or issue financial instruments for trading purposes. For a discussion of market risk, see “Quantitative and Qualitative Disclosure about Market Risk” in Item 7A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Our exposure to market risk has not changed materially since December 31, 2023.
Interest Rate Sensitivity
We had cash and cash equivalents, and marketable securities totaling $966.7 million as of September 30, 2024. Cash equivalents and marketable securities were invested primarily in U.S. agency and government sponsored securities, U.S. treasury securities, municipal bonds, commercial paper, corporate bonds, certificates of deposit and money market funds. Our investment policy is focused on the preservation of capital and supporting our liquidity needs. Under this policy, we invest in highly rated securities, while limiting the amount of credit exposure to any one issuer other than the U.S. government. We do not invest in financial instruments for trading or speculative purposes, nor do we use leveraged financial instruments. We utilize external investment managers who adhere to the guidelines of our investment policy. A hypothetical 100 basis point change in interest rates would not have a material impact on the value of our cash and cash equivalents or marketable investments.
As of September 30, 2024, aggregate principal amount outstanding of our 2025 and 2029 convertible senior notes was $1,181.9 million. The fair value of the convertible senior notes are subject to interest rate risk, market risk and other factors due to their conversion features. The fair value of the convertible senior notes will generally increase as our common stock price increases and will generally decrease as our common stock price declines. The interest and market value changes affect the fair value of the convertible senior notes but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligations. Additionally, we carry the convertible senior notes at face value less unamortized discount on our condensed consolidated balance sheets, and we present the fair value for required disclosure purposes only.
Our 2025 and 2029 convertible senior notes bear fixed interest rates and, therefore, are not subject to interest rate risk. We have not utilized derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions in any material fashion, except for the privately negotiated capped call transactions entered into in May and June 2020 related to the issuance of our 2025 convertible senior notes and entered into in March 2024 related to the issuance of our 2029 convertible senior notes.
Foreign Currency Risk
The functional currency of our foreign subsidiaries is the U.S. dollar. Our sales are primarily denominated in U.S. dollars and, therefore, our revenue is not directly subject to foreign currency risk. However, we are indirectly exposed to foreign currency risk. A stronger U.S. dollar makes our solution more expensive outside the United States and therefore can reduce demand. A weaker U.S. dollar could have the opposite effects. Such economic exposure to currency fluctuations is difficult to measure or predict because our sales are influenced by many factors in addition to the impact of currency fluctuations. Our operating expenses are generally denominated in the currencies of the countries in which our operations are located, except for Russia where compensation of our employees was primarily denominated in the U.S. dollar. In March 2022, we made a decision to close our Russia office in June 2022 and to establish a new European development center in Portugal.
Our consolidated results of operations and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign exchange rates. To date, we have not entered into any hedging arrangements with respect to foreign currency risk or other derivative financial instruments. During the nine months ended September 30, 2024, the effect of a hypothetical 10% change in foreign currency exchange rates applicable to our business would have a maximum impact of $7.2 million on our operating expenses.

ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of September 30, 2024.
Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2024, our disclosure controls and procedures were designed, and were effective, to provide assurance at a reasonable level that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosures.
In designing and evaluating our disclosure controls and procedures, management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.
Changes in Internal Control over Financial Reporting
During the three months ended September 30, 2024, there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION
ITEM 1. Legal Proceedings
Information with respect to this Item may be found under the heading “Legal Matters” in Note 10 to the condensed consolidated financial statements in this Quarterly Report on Form 10-Q, which information is incorporated herein by reference.
ITEM 1A. Risk Factors
Except for the below risk factors, which update those previously disclosed in our Annual Report on Form 10-K filed with the SEC on February 22, 2024, there have been no material changes from the Risk Factors previously disclosed in Part 1, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. In addition to the other information set forth in this report, including the below update to Risk Factors, you should carefully consider the Risk Factors discussed in our Annual Report on Form 10-K as they could materially affect our business, financial condition and future results of operation.
Risks Related to Ownership of Our Convertible Senior Notes
Servicing our debt may require a significant amount of cash. We may not have sufficient cash flow from our business to pay our indebtedness, and we may not have the ability to raise the funds necessary to settle conversions of the convertible senior notes in cash or to repurchase the convertible senior notes for cash upon a fundamental change, which could adversely affect our business and results of operations.
In May and June 2020, we issued $747.5 million in aggregate principal amount of the 2025 convertible senior notes in a private offering, $434.4 million of which was outstanding as of September 30, 2024. The 2025 convertible senior notes mature on June 1, 2025, and the interest rate of the 2025 convertible senior notes is fixed at 0.500% per annum, payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. In March 2024, we issued $747.5 million in aggregate principal amount of the 2029 senior notes in a private offering, all of which were outstanding as of September 30, 2024. The 2029 convertible senior notes mature on March 15, 2029, and the interest rate of the 2029 convertible senior notes is fixed at 1.000% per annum, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2024.
Our ability to make scheduled payments of principal and interest under our 2025 convertible senior notes and our 2029 convertible senior notes, or to refinance such indebtedness, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control, including those described in this report. Our business may not generate cash flows from operations in the future that are sufficient to service our indebtedness and make necessary capital expenditures. If we are unable to generate sufficient cash flows, we may be required to pursue one or more alternatives, such as selling assets, restructuring debt or obtaining additional debt financing or equity capital on terms that may be onerous or highly dilutive to existing holders of our common stock. Our ability to obtain additional financing or refinance the 2025 convertible senior notes, the 2029 convertible senior notes or any future indebtedness, will depend on conditions in the capital markets and our financial condition at such time, among other factors. We may not be able to engage in any of these activities on favorable terms or at all, which could result in a default on our debt obligations or other material adverse effects on our business and financial condition.
Subject to certain conditions, holders of the convertible senior notes have the right to require us to repurchase for cash all or any portion of their convertible senior notes upon the occurrence of a fundamental change (as defined in the indenture governing the convertible senior notes) at a fundamental change repurchase price equal to 100% of the principal amount of the convertible senior notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable fundamental change repurchase date.
Upon conversion of the convertible senior notes in accordance with their terms, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to settle a portion or all of our conversion obligation through the payment of cash. We may not have enough available cash or be able to obtain financing at the time we are required to make repurchases in connection with such conversion and our ability to pay may be further limited by law, regulatory authority or agreements governing our future indebtedness. Our failure to repurchase any convertible senior notes at a time when the repurchase is required by the applicable indenture or to pay any cash payable on any future conversions as required by such indenture would constitute a default under such indenture. A default under the applicable indenture would lead to, and the occurrence of the fundamental change itself may also lead to, a default under agreements governing our future indebtedness. If the repayment of the related indebtedness were to be
46

accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness or repurchase the convertible senior notes when required, or to make cash payments upon conversions thereof.
If triggered, the conditional conversion features of the convertible senior notes may adversely affect our financial condition and operating results.
If and to the extent the conditional conversion features of either or both series of our convertible senior notes are triggered, holders of such convertible senior notes will be entitled to convert their convertible senior notes at any time during specified periods at their option. During the three months ended September 30, 2024, the conversion features of the 2025 convertible senior notes were not triggered. Accordingly, holders of the 2025 convertible senior notes are not entitled to convert their convertible senior notes from October 1, 2024 to December 31, 2024. During the three months ended September 30, 2024, the conversion features of the 2029 convertible senior notes were not triggered. Accordingly, holders of the 2029 convertible senior notes are not entitled to convert their convertible senior notes from October 1, 2024 to December 31, 2024. Whether either or both series of our convertible senior notes will be convertible after December 31, 2024 will depend on the satisfaction of the applicable conversion conditions.
To the extent that the conditional conversion features of either or both series of our convertible senior notes are triggered in the future, holders of such convertible senior notes will be entitled to convert their convertible senior notes at any time during the specified periods at their option. If one or more holders elect to convert their convertible senior notes during any such specified period, we have the option to 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. Any election to settle conversions of convertible senior notes with cash could adversely affect our liquidity.
Transactions relating to the convertible senior notes may dilute the ownership interests of our existing stockholders or adversely affect the market price of our common stock; the trading price of our convertible senior notes may be affected by volatility in the price of our common stock.
The conversion of some or all of the convertible senior notes would dilute the ownership interests of our existing stockholders to the extent we satisfy our conversion obligation by delivering shares of our common stock. In this regard, if holders of the convertible senior notes elect to convert their notes, we may settle our conversion obligations by delivering to them cash, shares of our common stock or a combination thereof. In addition, we may issue shares of our common stock in connection with repurchases, exchanges or other transactions involving the convertible senior notes. Historically, we have elected to satisfy our convertible senior note conversion obligations through the payment of cash in certain circumstances, the issuance of shares of common stock in other circumstances, or a combination thereof, to such convertible senior note holders. See Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operation-Liquidity and Capital Resources, for further discussion of our elections to satisfy our conversion obligations.
In addition, in connection with the issuance of each series of the convertible senior notes, we entered into capped call transactions with certain financial institutions, or the Option Counterparties. The capped call transactions are expected generally to reduce the potential dilution to holders of our common stock upon any conversion or settlement of the convertible notes and/or offset any cash payments we are required to make in excess of the principal amount of such convertible senior notes, as the case may be, with such reduction and/or offset subject to a cap under the terms of the capped call transactions. We expect that the Option Counterparties or their respective affiliates may from time to time purchase shares of our common stock and/or enter into various derivative transactions with respect to our common stock in connection with their hedging activities relating to the capped call transactions. The Option Counterparties or their respective affiliates also may modify their hedge positions by entering into or unwinding such derivative transactions and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the applicable maturity of the convertible senior notes. These activities could negatively affect the market price of our common stock.
Volatility and declines in the trading price of our common stock may result in decreases in the trading prices of our convertible senior notes. Our convertible senior notes do not trade in a liquid market and are thus subject to increased volatility, particularly when our common stock price is volatile.

Description of Business and Summary of Significant Accounting Policies Description of Business and Summary of Significant Accounting Policies
Five9, Inc. and its wholly-owned subsidiaries (the “Company”) is a provider of cloud software for contact centers. The Company was incorporated in Delaware in 2001 and is headquartered in San Ramon, California. The Company has offices in Europe, Asia and Australia, which primarily provide research, development, sales, marketing, and client support services.
Basis of Presentation
The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“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 financial statements prepared in accordance with 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, 2023. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates
The preparation of condensed consolidated financial statements in accordance with 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The significant estimates made by management affect revenue and related reserves, as well as the fair value of assets acquired and liabilities assumed through business combinations and the fair value of performance-based restricted stock units ("PRSUs"). Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates.
Significant Accounting Policies
There have been no material changes from the significant accounting policies previously disclosed in Part II, Item 8, of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 as filed with the SEC on February 22, 2024.
Recent Accounting Pronouncements Not Yet Effective
In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ ASU”) No. 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. This ASU is effective for the Company’s fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company is currently evaluating the impact of this ASU on its consolidated financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires disclosure of specific categories in the effective tax rate reconciliation and additional information on income taxes paid. This ASU is effective for the Company’s fiscal years beginning after December 15, 2024. Early adoption is permitted and may be adopted on a prospective or retrospective basis. The Company is currently evaluating the impact of this ASU on its consolidated financial statement disclosures.

Contract assets and contract liabilities:
Contract assets (included in prepaid expenses and other current assets)$6,497 $4,106 
Contract liabilities (deferred revenue) (80,000)(68,187)
Noncurrent contract liabilities (deferred revenue) (included in other long-term liabilities)(627)(1,350)
Net contract liabilities$(74,130)$(65,431)
The Company receives payments from customers based upon billing cycles. Invoice payment terms are usually 30 days or less. Accounts receivable are recorded when the right to consideration becomes unconditional.
Deferred contract acquisition costs are recorded when incurred and are amortized over an estimated customer benefit period of five years.
The Company’s contract assets consist of unbilled amounts typically resulting from professional services revenue recognition when it exceeds the total amounts billed to the customer. The Company’s contract liabilities consist of advance payments and billings in excess of revenue recognized.
In the three and nine months ended September 30, 2024, the Company recognized revenue of $5.6 million and $52.3 million, respectively, related to its contract liabilities at December 31, 2023.
Remaining Performance Obligations
As of September 30, 2024, the aggregate amount of the total transaction price allocated in contracts with original duration of greater than one year to the remaining performance obligations was $1,100.4 million. The Company expects to recognize revenue on approximately three-fourths of the remaining performance obligations over the next 24 months, with the balance recognized thereafter. The Company excludes amounts for remaining performance obligations that are part of contracts with an original expected duration of one year or less. Such remaining performance obligations represent unsatisfied or partially unsatisfied performance obligations.

Although the Company had certain available-for-sale debt securities in an unrealized loss position as of September 30, 2024, no impairment loss was recorded since it did not intend to sell them, did not anticipate a need to sell them, and the decline in fair value was not due to any credit-related factors.

Fair Value Measurements
The Company carries cash equivalents and marketable investments at fair value. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
Level 1 — Observable inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 — Observable inputs other than Level 1 inputs, such as quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 — Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques.
The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments.
Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. The Company performs routine procedures such as comparing prices obtained from independent sources to ensure that appropriate fair values are recorded.

In March 2024, the Company issued $747.5 million aggregate principal amount of 1.00% convertible senior notes due 2029 (the "2029 convertible senior notes") in a private offering. In connection with the issuance of the 2029 convertible senior notes, the Company used part of the net proceeds from the issuance to repurchase approximately $313.1 million aggregate principal amount of its 0.50% convertible senior notes due 2025 (the "2025 convertible senior notes"). As of September 30, 2024 and December 31, 2023, the estimated fair value of the Company's outstanding 2025 convertible senior notes was $419.4 million and $718.3 million, respectively. As of September 30, 2024, the estimated fair value of the Company's outstanding 2029 convertible senior notes was $628.0 million. The fair values were determined based on the quoted price of the convertible senior notes in an inactive market on the last trading day of the reporting period and have been classified as Level 2 in the fair value hierarchy. See Note 6 for further information on the Company’s convertible senior notes.
In February 2022, the Company made a $2.0 million equity investment in a privately-held company that the Company does not have the ability to exercise significant influence over. The Company elected to utilize the measurement alternative for an equity security without a readily determinable fair value. Accordingly, this investment is accounted for at its cost minus impairment, if any, and is classified within Level 3. If the Company identifies observable price changes in orderly transactions for such investment or a similar investment, it will measure the investment at fair value as of the date that the observable transactions or events occurred. During the third quarter of 2024, the Company noted an indicator of impairment of this investment and recorded a $1.3 million impairment charge.
Except for the equity investment described above, there were no assets or liabilities measured at fair value on a non-recurring basis as of September 30, 2024 and December 31, 2023.
The fair value of the Company’s other financial instruments, including accounts receivable, accounts payable and other current liabilities, approximate their carrying value due to the relatively short maturity of those instruments. The carrying amounts of the Company’s operating and finance leases approximate their fair value, which is the present value of expected future cash payments based on assumptions about current interest rates and the creditworthiness of the Company.

Debt Debt
Repurchase Transaction
In connection with the issuance of the 2029 convertible senior notes on March 1, 2024, the Company used part of the net proceeds from the issuance to repurchase approximately $313.1 million aggregate principal amount of
the outstanding 2025 convertible senior notes in privately-negotiated transactions for aggregate cash consideration of approximately $304.9 million (the “Repurchase Transaction”).
The Repurchase Transaction was accounted for as a debt extinguishment. The difference between the consideration used to extinguish the 2025 convertible senior notes and the carrying value of the 2025 convertible senior notes (including unamortized debt discount and issuance costs) resulted in an extinguishment gain of approximately $6.6 million recorded through Other income (expense), net on the Company’s condensed consolidated statements of operations and comprehensive loss.
In connection with the Repurchase Transaction, the Company also entered into a partial termination agreement with each bank counterparty and unwound a corresponding portion of the previously purchased capped call instruments entered into in connection with the issuance of the 2025 convertible senior notes (the “2025 Capped Calls”). The Company received approximately $0.5 million in cash in connection with these partial terminations, representing the fair value at the date of settlement of the unwound 2025 Capped Calls.
2029 Convertible Senior Notes and Related Capped Call Transactions
In March 2024, the Company issued $747.5 million aggregate principal amount of 2029 convertible senior notes in a private offering, which aggregate principal amount included the exercise in full of the initial purchasers’ option to purchase up to an additional $97.5 million principal amount of the 2029 convertible senior notes. The 2029 convertible senior notes mature on March 15, 2029 and bear interest at a fixed rate of 1.00% per annum, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2024. The total net proceeds from the issuance of the 2029 convertible senior notes, after deducting initial purchasers' discounts and commissions and estimated debt issuance costs, were approximately $728.8 million.
Each $1,000 principal amount of the 2029 convertible senior notes is initially convertible into 12.5918 shares of the Company’s common stock (the “2029 Conversion Option”), which is equivalent to an initial conversion price of approximately $79.42 per share of common stock, subject to adjustment upon the occurrence of specified events. The initial conversion price represents a premium of approximately 30% to the $61.09 per share closing price of the Company’s common stock on The Nasdaq Global Market on February 27, 2024. There have been no changes to the initial conversion price of the 2029 convertible senior notes since issuance. The 2029 convertible senior notes are convertible, in multiples of $1,000 principal amount, at the option of the holders prior to the close of business on the business day immediately preceding December 15, 2028, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2024 (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; (2) during the five business day period after any five consecutive trading day period (the “2029 Measurement Period”) in which the trading price (as defined in the 2029 Indenture governing the 2029 convertible senior notes) per $1,000 principal amount of the 2029 convertible senior notes for each trading day of the 2029 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 in effect on each such trading day; (3) if the Company calls any or all of the 2029 convertible senior notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after December 15, 2028 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 2029 convertible senior notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.
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 the Company’s common stock, at the Company’s election. If the Company undergoes a fundamental change (as defined in the indenture governing the 2029 convertible senior notes), subject to certain conditions, holders may require the Company to repurchase for cash all or any portion of their 2029 convertible senior notes, in principal amounts of $1,000 or a multiple thereof, at a fundamental change repurchase price equal to 100% of the principal amount of the 2029 convertible senior notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events or if the Company issues a notice of redemption, it will, under certain circumstances, increase the conversion rate for holders who elect to convert their notes in connection with such corporate event or during the relevant redemption period.
The closing market price of the Company's common stock of $28.73 per share on September 30, 2024, the last trading day during the three months ended September 30, 2024, was below $103.24 per share, which represents 130% of the initial conversion price of $79.42 per share. Additionally, 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, September 30, 2024, was not greater than or equal to 130% of
the initial conversion price. As such, during the three months ended September 30, 2024, the conditions allowing holders of the 2029 convertible senior notes to convert were not met. The 2029 convertible senior notes are therefore not convertible during the three months ending December 31, 2024.
The Company may not redeem the 2029 convertible senior notes prior to March 22, 2027. The Company may redeem for cash all or any portion of the 2029 convertible senior notes, at its option, on or after March 22, 2027 and prior to December 15, 2028, if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such 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 2029 convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. However, the Company may not redeem less than all of the outstanding 2029 convertible senior notes unless at least $100.0 million aggregate principal amount of 2029 convertible senior notes are outstanding and not called for redemption at the time the redemption notice is sent. No sinking fund is provided for the 2029 convertible senior notes.
The 2029 convertible senior notes are the Company’s senior unsecured obligations and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 2029 convertible senior notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated (including the 2025 convertible senior 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 indebtedness and other liabilities.

The debt issuance costs are amortized into interest expense over the term of the 2029 convertible senior notes at an effective interest rate of 1.49%.
In connection with the issuance of the 2029 convertible senior notes, the Company entered into privately negotiated capped call transactions (each a “2029 Capped Call,” and collectively the "2029 Capped Calls") with certain financial institutions. The 2029 Capped Call has an initial strike price of approximately $79.42, subject to certain adjustments, which corresponds to the initial conversion price of the 2029 convertible senior notes. The 2029 Capped Calls have an initial cap price of $122.18 per share, subject to certain adjustments. The 2029 Capped Calls are expected to partially offset the potential dilution to the Company’s common stock upon any conversion of the 2029 convertible senior notes, with such offset subject to a cap based on the cap price. Each 2029 Capped Call covers, subject to anti-dilution adjustments, approximately 9.4 million shares of the Company’s common stock. The 2029 Capped Call is subject to adjustment upon the occurrence of specified extraordinary events affecting the Company, including merger events, tender offers, and announcement events. In addition, each 2029 Capped Call is subject to certain specified additional disruption events that may give rise to a termination of the 2029 Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings, and hedging disruptions. For accounting purposes, each 2029 Capped Call is treated as a separate transaction from, and not part of the terms of the 2029 convertible senior notes. As these transactions meet certain accounting criteria, the 2029 Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The 2029 Capped Calls will not be remeasured as long as they continue to meet the conditions for equity classification.
2025 Convertible Senior Notes and Related Capped Call Transactions
In May and June 2020, the Company issued $747.5 million aggregate principal amount of 2025 convertible senior notes in a private offering, which aggregate principal amount included the exercise in full of the initial purchasers’ option to purchase up to an additional $97.5 million principal amount of the 2025 convertible senior notes. The 2025 convertible senior notes mature on June 1, 2025 and bear interest at a fixed rate of 0.500% per annum, payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. The total net proceeds from the issuance of the 2025 convertible senior notes, after deducting initial purchasers' discounts and commissions and estimated debt issuance costs, were approximately $728.8 million.
In March 2024, the Company used part of the net proceeds from the issuance of the 2029 convertible senior notes to repurchase $313.1 million aggregate principal amount of the 2025 convertible senior notes in privately-negotiated transactions. As of September 30, 2024, after giving effect to the Repurchase Transaction, approximately $434.4 million aggregate principal amount of 2025 convertible senior notes remained outstanding.
Each $1,000 principal amount of the 2025 convertible senior notes is initially convertible into 7.4437 shares of the Company’s common stock (the “2025 Conversion Option”), which is equivalent to an initial conversion price of approximately $134.34 per share of common stock, subject to adjustment upon the occurrence of specified events. The initial conversion price represents a premium of approximately 30% to the $103.34 per share closing price of the Company’s common stock on The Nasdaq Global Market on May 21, 2020. There have been no changes to the initial conversion price of the 2025 convertible senior notes since issuance. The 2025 convertible senior notes are convertible, in multiples of $1,000 principal amount, at the option of the holders prior to the close of business on the business day immediately preceding March 1, 2025, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 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; (2) during the five business day period after any five consecutive trading day period (the “2025 Measurement Period”) in which the trading price (as defined in the 2025 Indenture governing the 2025 convertible senior notes) per $1,000 principal amount of the 2025 convertible senior notes for each trading day of the 2025 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 in effect on each such trading day; (3) if the Company calls any or all of the 2025 convertible senior notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after March 1, 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 2025 convertible senior notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. 
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 the Company’s common stock, at the Company’s election. If the Company undergoes a fundamental change (as defined in the indenture governing the 2025 convertible senior notes), subject to certain conditions, holders may require the Company to repurchase for cash all or any portion of their 2025 convertible senior notes, in principal amounts of $1,000 or a multiple thereof, at a fundamental change repurchase price equal to 100% of the principal amount of the 2025 convertible senior notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events or if the Company issues a notice of redemption, it will, under certain circumstances, increase the conversion rate for holders who elect to convert their notes in connection with such corporate event or during the relevant redemption period.
The closing market price of the Company's common stock of $28.73 per share on September 30, 2024, the last trading day during the three months ended September 30, 2024, was below $174.64 per share, which represents 130% of the initial conversion price of $134.34 per share. Additionally, 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, September 30, 2024, was not greater than or equal to 130% of the initial conversion price. As such, during the three months ended September 30, 2024, the conditions allowing holders of the 2025 convertible senior notes to convert were not met. The 2025 convertible senior notes are therefore not convertible during the three months ending December 31, 2024.
The 2025 convertible senior notes became redeemable at the Company's option on June 6, 2023. The Company may redeem for cash all or any portion of the 2025 convertible senior notes, at its option, prior to March 1, 2025, if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending not more than two trading days 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 2025
convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the 2025 convertible senior notes. During the three months ended September 30, 2024, the conditions allowing the Company to redeem for cash all or any portion of the 2025 convertible senior notes were not met.
The 2025 convertible senior notes are the Company’s senior unsecured obligations and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 2025 convertible senior notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; 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 indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

In connection with the issuance of the 2025 convertible senior notes, the Company entered into privately negotiated capped call transactions (each a “2025 Capped Call,” and collectively the "2025 Capped Calls") with certain financial institutions. The 2025 Capped Calls each have an initial strike price of approximately $134.34, which corresponds to the initial conversion price of the 2025 convertible senior notes. The initial cap price of the 2025 Capped Calls was $206.68 per share and is subject to certain adjustments under the terms of the 2025 Capped Calls. In connection with the Repurchase Transaction, the Company unwound a portion of the 2025 Capped Calls. Refer to the Repurchase Transaction section above for further information. There are no changes or amendments made to the remaining 2025 Capped Calls. The remaining 2025 Capped Calls cover, subject to anti-dilution adjustments, approximately 3.2 million shares of the Company’s common stock. Each 2025 Capped Call is subject to adjustment upon the occurrence of specified extraordinary events affecting the Company, including merger events, tender offers, and announcement events. In addition, each 2025 Capped Call is subject to certain specified additional disruption events that may give rise to a termination of each 2025 Capped Call, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings, and hedging disruptions. For accounting purposes, each 2025 Capped Call is a separate transaction from, and not part of the terms of the 2025 convertible senior notes. As these transactions meet certain accounting criteria, the 2025 Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The 2025 Capped Calls will not be remeasured as long as they continue to meet the conditions for equity classification.

PRSUs with Market and Service Conditions In 2022, the Company granted 284,282 PRSUs subject to market and service conditions (“market-based PRSUs”) with a grant date fair value of $30.6 million as part of its annual grant of equity incentive awards to certain executives and in connection with the appointment of Michael Burkland as its new Chief Executive Officer. In 2023, the Company granted 35,921 market-based PRSUs with a grant date fair value of $3.1 million. During the nine months ended September 30, 2024, the Company granted an additional
159,016 market-based PRSUs with a grant date fair value of $9.6 million. The amount that may be earned pursuant to the market-based PRSUs ranges from 0% to 200% of the target number based on the Company’s relative total shareholder return (“RTSR”) performance as compared to the companies in the S&P Software and Services Select Index during three one-year performance periods. One-third of the total market-based PRSUs may be earned and settled in shares following the end of each performance period based on RTSR performance and subject to continued employment through the payment date. If the Company’s absolute total shareholder return for any performance period is negative, then no more than 100% of the target amount of market-based PRSUs for such period may be earned. If an executive's employment with the Company terminates before the end of the final one-year performance period due to death or disability, 100% (if due to death) or 50% (if due to disability) of the unvested market-based PRSUs may be earned subject to ultimate RTSR performance in each remaining performance period. Upon a qualifying termination of employment in connection with a change in control of the Company, the unvested market-based PRSUs will vest on a double-trigger basis (i) at the target level for the market-based PRSUs subject to the 2022-2024 performance period, (ii) for the market-based PRSUs subject to the 2023-2025 performance period, and (iii) for the market-based PRSUs subject to the 2024-2026 performance period, (a) at the target level for the uncompleted portions of the performance periods and (b) at the actual level of performance measured through the date of the change in control of the Company, based on the price per share paid in such change in control. The fair value of the market-based PRSUs is determined on their grant date using a Monte Carlo Simulation model based upon assumptions presented below. The Company recognizes the fair value of the market-based PRSUs ratably over their requisite service period.
During the first quarter of 2023, the Company certified the performance results for the 2022 measurement period for the market-based PRSUs subject to the 2022-2024 performance period. Under the market-based PRSU agreements, the TSR payout percentage ranges from 0% to 200%, with a 50% payout at the 25th TSR percentile (threshold), 100% payout at the 55th TSR percentile (target), 200% payout at the 90th percentile or greater (maximum) and no payout below the threshold performance level. The Company determined that its actual total shareholder return was -52.64% for 2022, and that its relative total shareholder return ranking was in the 30.2 percentile relative to companies in the S&P Software & Services Select Index, which resulted in a payout percentage of 58.7% of target. During the first quarter of 2024, the Company certified the performance results for the 2023 measurement period for the market-based PRSUs subject to the 2022-2024 performance period. The Company determined that its actual total shareholder return was 19.95% for 2023, and that its relative total shareholder return ranking was in the 53.8 percentile relative to companies in the S&P Software & Services Select Index, which resulted in a payout percentage of 98.0% of target. During the first quarter of 2024, the Company also certified the performance results for the 2023 measurement period for the market-based PRSUs subject to the 2023-2025 performance period. The Company determined that its actual total shareholder return was 19.95% for 2023, and that its relative total shareholder return ranking was in the 50.5 percentile relative to companies in the S&P Software & Services Select Index, which resulted in a payout percentage of 92.5% of target.
PRSUs with Revenue and Service Conditions In 2022, the Company granted 66,167 PRSUs subject to revenue-based performance and service conditions (“revenue-based PRSUs”) with a grant date fair value of $6.6 million. The amount of revenue-based PRSUs that may be earned will be determined based on achievement of two quarterly revenue goals. One third of the revenue-based PRSUs may be earned based on achievement of the first revenue target and, if achieved, will vest in four quarterly installments, with the first installment occurring on the date such achievement is certified, subject to the executive's continuous service through the applicable vesting dates. Two thirds of the revenue-based PRSUs may be earned based on achievement of the second revenue target and, if achieved, will vest in eight quarterly installments, with the first installment occurring on the date such achievement is certified, subject to the executive's continuous service through the applicable vesting dates. The revenue-based PRSUs are otherwise on the Company's standard award terms for its market-based PRSUs. During 2023, the Company certified that the first revenue target was achieved, and thus recognized the related stock-based compensation expense for this first revenue target. However, the Company certified during the first quarter of 2024
that, as of December 31, 2023, the second revenue target was not achieved, and thus did not recognize the related stock-based compensation expense and cancelled the shares associated with this target.

Earnings Per Share [Abstract]  
Net Loss Per Share Net Loss Per Share
Basic net loss per share is calculated by dividing net loss by the weighted average number of shares of common stock outstanding during the period, and excludes any dilutive effects of employee stock-based awards and potential shares upon conversion of the convertible senior notes. Diluted net loss per share is computed giving effect to all potentially dilutive shares of common stock, including common stock issuable upon exercise of stock options, vesting of RSUs and PRSUs, and shares of common stock issuable upon conversion of convertible senior notes. As the Company had net losses for the three and nine months ended September 30, 2024 and 2023, all potentially issuable shares of common stock were determined to be anti-dilutive.
The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):

The Company used the if-converted method for calculating any potential dilutive effect of its convertible senior notes for the three and nine months ended September 30, 2024 and 2023. Under this method, the Company calculates diluted earnings per share under both the cash and share settlement assumptions to determine which is more dilutive. If share settlement is more dilutive, the Company calculates diluted earnings per share assuming that all of the convertible senior notes were converted solely into shares of common stock at the beginning of the reporting period. The potential impact upon the conversion of the convertible senior notes were excluded from the calculation of diluted net loss per share for the three and nine months ended September 30, 2024 and 2023 because the effect would have been anti-dilutive.

Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
The (benefit from) provision for income taxes for the three and nine months ended September 30, 2024 was approximately $(3.9) million and $0.5 million, respectively. The provision for income taxes for the three and nine months ended September 30, 2023 was approximately $0.9 million and $2.2 million, respectively.

The benefit from income taxes for the three months ended September 30, 2024 was primarily related to the Company's acquisition of Acqueon, which included a domestic net deferred tax liability balance of $4.8 million and provided the Company with a source of taxable income to release a portion of its U.S.valuation allowance. The provision for income taxes for the nine months ended September 30, 2024 consisted primarily of U.S. federal and U.S. state tax expense as a result of IRC Section 174 research and experimental capitalization requirements and tax attribute utilization limitations, and foreign current income tax expense as a result from income produced by the Company's intercompany cost-plus operating model, which were partially offset by the benefit related to the Company's acquisition of Acqueon, discussed above. The provision for income taxes for the three and nine months ended September 30, 2023 consisted primarily of current U.S. state tax expense due to the lack of available net operating losses to offset the taxable income generated and foreign income tax expense due to the Company's intercompany cost-plus operating model.
For the three and nine months ended September 30, 2024, the (benefit from) provision for income taxes differed from the statutory amount primarily due to the domestic full valuation allowance position maintained against the domestic net deferred tax assets, and the partial release discussed above. For the three and nine months ended September 30, 2023, the provision for income taxes differed from the statutory amount primarily due to domestic state income taxes, foreign income taxes and the Company realizing no benefit for prior year domestic losses due to maintaining a full valuation allowance against its domestic net deferred tax assets.
The realization of tax benefits from deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, to be recognized in the periods the items are expected to be deductible or taxable. Based on the weight of the available objective evidence, the Company does not believe it is more likely than not that the U.S. net deferred tax assets will be realizable. Accordingly, the Company has provided a full valuation allowance against
such net deferred tax assets as of September 30, 2024 and December 31, 2023. The Company intends to maintain the valuation allowance until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance. During the three and nine months ended September 30, 2024, there were no material changes to the total amount of unrecognized tax benefits.

Legal Matters
The Company is involved in various legal and regulatory matters arising in the normal course of business. In management’s opinion, resolution of these matters is not expected to have a material impact on the Company’s consolidated results of operations, cash flows, or its financial position. However, due to the uncertain nature of legal matters, an unfavorable resolution of a matter could materially affect the Company’s future consolidated results of operations, cash flows or financial position in a particular period. The Company expenses legal fees as incurred.
Indemnification Agreements
In the ordinary course of business, the Company enters into agreements of varying scope and terms pursuant to which it agrees to indemnify clients, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, including breach of security, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with its directors, officers and certain employees that requires it, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. There are no claims that the Company is aware of that could have a material effect on the consolidated balance sheets, consolidated statements of operations and comprehensive loss, or consolidated statements of cash flows.

Leases Leases
The Company has leases for offices, data centers and computer and networking equipment that expire at various dates through 2031. The Company’s leases have remaining terms of one to seven years, some of the leases include a Company option to extend the leases for up to one to five years, and some of the leases include the option to terminate the leases upon 30-days' notice. The Company does not separate lease and non-lease components for real estate operating leases. The Company entered into three-year equipment finance lease agreements and recognized $18.6 million right of use assets during the three months ended September 30, 2024, which were reported within "Finance lease right-of-use assets" and are being depreciated on a straight-line basis over the lease term. As a result, the Company also recognized short-term lease liabilities of $5.9 million within "Finance lease liabilities" and long-term lease liabilities of $12.7 million within "Finance lease liabilities - less current portion" for the three months ended September 30, 2024.

Acquisitions Acquisitions
Acqueon
On August 27, 2024, the Company acquired all of the issued and outstanding shares of capital stock of Acqueon for total consideration of approximately $173.8 million. This acquisition, which was accounted for as a business combination, is intended to build on the pre-existing partnership between the companies, and to extend the Company's AI-powered CX platform by adding omnichannel proactive customer engagement to expand Five9’s outbound capabilities.
The excess of the purchase price over identifiable intangible assets and net tangible assets in the amount of $138.2 million was allocated to goodwill, which is not deductible for tax purposes. The fair values assigned to assets acquired and liabilities assumed are based on management’s best estimates and assumptions as of the acquisition date and are considered preliminary pending finalization of valuation analyses pertaining to intangible assets acquired, liabilities assumed and tax liabilities assumed. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. The following table presents the preliminary allocation of the purchase price at the acquisition date (in thousands):
Cash$6,661 
Tangible assets acquired 4,580 
Other assets acquired7,333

Goodwill138,181 
Total assets acquired196,655 
Deferred tax liability(4,831)
Liabilities assumed(17,997)
         Total$173,827 
The acquired technology, customer relationships, and trademarks will be amortized on a straight-line basis over their estimated useful lives of eight years, five years, and three years, respectively. The Company used the income approach to estimate the fair value of intangible assets acquired.
In connection with this acquisition, the Company incurred total acquisition-related transaction costs of $2.0 million and $5.3 million during the three and nine months ended September 30, 2024, respectively, which have been expensed as incurred and included in general and administrative expenses in the consolidated statements of operations and comprehensive loss.
The results of operations of this acquisition are included in the accompanying consolidated statements of operations and comprehensive loss from the date of acquisition and are not material to the Company's condensed consolidated financial statements.
Aceyus
On August 14, 2023, the Company acquired all of the issued and outstanding shares of capital stock of Aceyus, Inc. ("Aceyus") for total cash consideration of approximately $82.0 million. This acquisition, which was accounted for as a business combination, is intended to accelerate the Company's ability to capitalize on two business opportunities, namely facilitating the migration of large enterprise customers from on-premise to cloud and leveraging contextual data to deliver personalized experiences throughout the customer journey, including using this contextual data in the Company's AI & Automation solutions.
The excess of the purchase price over identifiable intangible assets and net tangible assets in the amount of $61.8 million was allocated to goodwill, which is not deductible for tax purposes. The fair values assigned to assets acquired and liabilities assumed are based on management’s best estimates and assumptions as of the reporting date and are considered final. The Company recorded an adjustment of $0.1 million during the one year from acquisition date measurement period. The following table presents the final allocation of the purchase price at the acquisition date (in thousands):

Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“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 financial statements prepared in accordance with 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, 2023. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates
Use of Estimates
The preparation of condensed consolidated financial statements in accordance with 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The significant estimates made by management affect revenue and related reserves, as well as the fair value of assets acquired and liabilities assumed through business combinations and the fair value of performance-based restricted stock units ("PRSUs"). Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates.

In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ ASU”) No. 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. This ASU is effective for the Company’s fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company is currently evaluating the impact of this ASU on its consolidated financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires disclosure of specific categories in the effective tax rate reconciliation and additional information on income taxes paid. This ASU is effective for the Company’s fiscal years beginning after December 15, 2024. Early adoption is permitted and may be adopted on a prospective or retrospective basis. The Company is currently evaluating the impact of this ASU on its consolidated financial statement disclosures.
