REVENUE RECOGNITION

6 Months Ended

Sep. 30, 2023

Revenue from Contract with Customer [Abstract]

REVENUE RECOGNITION

Disaggregation of Revenue

The Company disaggregates its revenue by geographic region. See Note 10. Geographical Information.

Contract Balances

The following table provides amounts of receivables, contract assets, and deferred revenue from contracts with customers (in thousands):


	September 30, 2023		March 31, 2023
Accounts receivable, net	$	61,063	$	62,307
Contract assets, current (component of Other current assets)	11,317		11,581
Contract assets, non-current (component of Other assets)	9,639		11,141
Deferred revenue, current	33,223		34,909
Deferred revenue, non-current	10,231		10,615

The change in contract assets was primarily driven by billing customers for amounts that had previously been recognized in revenue but not yet billed. The decrease in deferred revenue was due to reduced billings done in advance of performance obligations being satisfied. During the six months ended September 30, 2023, the Company recognized revenues of approximately $28.6 million that were included in deferred revenue at the beginning of the fiscal year.

Remaining Performance Obligations

The Company's subscription terms typically range from one to five years. Contract revenue from the remaining performance obligations that had not yet been recognized as of September 30, 2023 was approximately $780.0 million. This amount excludes contracts with an original expected length of less than one year. The Company expects to recognize revenue on approximately 86% of the remaining performance obligations over the next 24 months and approximately 14% over the remainder of the subscription period.

For purposes of this disclosure, the Company excludes contracts with an original expected length of less than one year. Since the new and renewal contracts entered into with customers are generally for terms of one year or longer, updating this disclosure to include contracts with a term of one year or more presents a more appropriate measure of the Company's remaining performance obligations.

Deferred Sales Commission Costs

Amortization of deferred sales commission costs for the three months ended September 30, 2023 and 2022 was approximately $10.1 million and $9.6 million, respectively, and $20.1 million and $18.8 million during the six months ended September 30, 2023 and 2022, respectively. There were no material write-offs during the three and six months ended September 30, 2023 and 2022.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

("8x8" or the "Company") was incorporated in California in February 1987 and was reincorporated in Delaware in December 1996. The Company trades under the symbol "EGHT" on the Nasdaq Global Select Market. The Company is a leading Software-as-a-Service ("SaaS") provider of contact center, voice, video, chat, and enterprise-class API solutions powered by one global cloud communications platform. 8x8 empowers workforces worldwide by connecting individuals and teams, so they can collaborate faster and work smarter from anywhere. 8x8 provides real-time business analytics and intelligence, giving its customers unique insights across all interactions and channels on its platform, so they can support a distributed and hybrid working model while delighting their end-customers and accelerating their business. A majority of all revenue is generated from communication services subscriptions and platform usage. The Company also generates revenue from sales of hardware and professional services, which are complementary to the delivery of its integrated technology platform. BASIS OF PRESENTATION AND CONSOLIDATION The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Accordingly, certain information and disclosures normally included in the Company's annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended March 31, 2023 and notes thereto included in the Form 10-K. There were no material changes during the three and six months ended September 30, 2023 to the Company's significant accounting policies as described in the Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company conducts its operations through one reportable segment. In the opinion of the Company's management, these condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the Company's financial position, results of operations and cash flows for the periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending March 31, 2024. USE OF ESTIMATES The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to current expected credit losses, returns reserve for expected cancellations, fair value of and/or potential impairment of goodwill and value and useful life of long-lived assets (including intangible assets and right-of-use assets), capitalized internal-use software costs, benefit period for deferred commissions, stock-based compensation, incremental borrowing rate used to calculate operating lease liabilities, income and sales tax liabilities, convertible senior notes fair value, litigation, and other contingencies. The Company bases its estimates on known facts and circumstances, historical experience, and various other assumptions. Actual results could differ from those estimates under different assumptions or conditions. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS There were no recent accounting pronouncements that were applicable to the Company adopted during the six months ended September 30, 2023. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED Recent accounting pronouncements that may be applicable to the Company are not expected to have a material impact on its present or future financial statements.

The restricted cash component of the money market funds is comprised of letters of credit securing leases for certain office facilities.

The Company considers its investments available to support its current operations and has classified investments in debt securities as available-for-sale securities. The Company does not intend to sell any of its investments that are in unrealized loss positions and, as of September 30, 2023, has determined that it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis.

The Company regularly reviews the changes to the rating of its securities at the individual security level by rating agencies and reasonably monitors the surrounding economic conditions to assess the risk of expected credit losses. As of September 30, 2023, the Company did not record any allowance for credit losses on its investments.

The Company uses the Black-Scholes option-pricing valuation model to value its detachable warrants from inception and at each reporting period. Changes in the fair values of the detachable warrants liability are recorded as loss on warrants remeasurement within Other (expense) income, net in the condensed consolidated statements of operations.

The following table presents additional information about valuation techniques and inputs used for the detachable warrants (see Note 6, Convertible Senior Notes and Term Loan) that are measured at fair value and categorized within Level 3 as of September 30, 2023 and March 31, 2023 (dollars in thousands):


	September 30, 2023		March 31, 2023
Estimated fair value of detachable warrants	$	2,966	$	5,497
Unobservable inputs:
Stock volatility	80.0%		67.2%
Risk-free rate	4.7%		3.6%
Expected term	3.9 years		4.4 years

As of September 30, 2023 and March 31, 2023, the estimated fair value of the Company's convertible senior notes due in 2024 was $60.2 million and $57.3 million, respectively, and the estimated fair value of the Company’s convertible senior notes due in 2028 was $192.0 million and $183.0 million, respectively (see Note 6, Convertible Senior Notes and Term Loan). The fair value of the convertible senior notes was determined based on the closing price of each of the securities on the last trading day of the reporting period, and each is considered to be Level 2 in the fair value hierarchy due to limited trading activity of the debt instruments. As of September 30, 2023 and March 31, 2023, the carrying value of the Company’s Term Loan approximates its estimated fair value.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

COMMITMENTS AND CONTINGENCIES	6 Months Ended
COMMITMENTS AND CONTINGENCIES	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Indemnifications In the normal course of business, the Company may agree to indemnify other parties, including customers, lessors, and parties to other transactions with the Company with respect to certain matters, such as breaches of representations or covenants or intellectual property infringement or other claims made by third parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors. It is not possible to determine the maximum potential amount of the Company's exposure under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on the Company's operating results, financial position, or cash flows. Under some of these agreements, however, the Company's potential indemnification liability may not have a contractual limit. Operating Leases The Company's lease obligations consist of the Company's principal facility and various leased facilities under operating lease agreements. No material leases were executed during the three months ended September 30, 2023. See Note 5. Leases in the Company's Form 10-K for more information on the Company's leases and the future minimum lease payments. Purchase Obligations The Company's purchase obligations include contracts with third-party customer support vendors and third-party network service providers. These contracts include minimum monthly commitments and the requirements to maintain the service level for several months. During the six months ended September 30, 2023, the Company entered into a $28.1 million noncancellable three-year hosting service contract. Under this agreement, $3.8 million remains due during fiscal year 2024, $10.0 million will be due during fiscal 2025, and $10.5 million will be due during fiscal 2026. Legal Proceedings The Company may be involved in various claims, lawsuits, investigations, and other legal proceedings, including intellectual property, commercial, regulatory compliance, securities, and employment matters that arise in the normal course of business. The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. The Company regularly evaluates current information to determine whether any accruals should be adjusted and whether new accruals are required. Actual claims could settle or be adjudicated against the Company in the future for materially different amounts than the Company has accrued due to the inherently unpredictable nature of litigation. Legal costs are expensed as incurred. The Company believes it has recorded adequate provisions for any such lawsuits and claims and proceedings as of September 30, 2023. The Company believes that damage amounts claimed in these matters are not meaningful indicators of potential liability. Some of the matters pending against the Company involve potential compensatory, punitive, or treble damage claims or sanctions, that, if granted, could require the Company to pay damages or make other expenditures in amounts that could have a material adverse effect on its consolidated financial statements. Given the inherent uncertainties of litigation, the ultimate outcome of the ongoing matters described herein cannot be predicted, and the Company believes it has valid defenses with respect to the legal matters pending against it. Nevertheless, the consolidated financial statements could be materially adversely affected in a particular period by the resolution of one or more of these contingencies. State and Local Taxes and Surcharges From time to time, the Company has received inquiries from a number of state and local taxing agencies with respect to the remittance of sales, use, telecommunications, excise, and income taxes. Several jurisdictions currently are conducting tax audits of the Company's records. The Company collects or has accrued amounts for taxes that it believes are required to be remitted. The amounts that have been remitted have historically been within the accruals established by the Company. The Company adjusts its accrual when facts relating to specific exposures warrant such adjustment. During the second quarter of fiscal 2019, the Company conducted a periodic review of the taxability of its services and determined that certain services may be subject to sales, use, telecommunications or other similar indirect taxes in certain jurisdictions. A similar review was performed on the taxability of services provided by Fuze, Inc., and it was determined that certain services may be subject to sales, use, telecommunications or other similar indirect taxes in certain jurisdictions. Accordingly, the Company recorded contingent indirect tax liabilities. As of September 30, 2023 and March 31, 2023, the Company had accrued contingent indirect tax liabilities of $15.1 million and $13.5 million, respectively.

INCOME TAXES	6 Months Ended
INCOME TAXES	Sep. 30, 2023
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESThe Company's effective tax rate was 5.0% and (5.4)% for the three months ended September 30, 2023 and 2022, respectively. The difference in the effective tax rate and the U.S. federal statutory rate was primarily due to the full valuation allowance the Company maintains against its deferred tax assets after adjusting for the impact of certain provisions enacted under the Tax Cuts and Jobs Act, current tax liabilities of profitable foreign subsidiaries subject to different local income tax rates, and state taxes in the United States. The effective tax rate is calculated by dividing the provision for income taxes by the loss before provision for income taxes.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	BASIS OF PRESENTATION AND CONSOLIDATION The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Accordingly, certain information and disclosures normally included in the Company's annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended March 31, 2023 and notes thereto included in the Form 10-K. There were no material changes during the three and six months ended September 30, 2023 to the Company's significant accounting policies as described in the Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company conducts its operations through one reportable segment. In the opinion of the Company's management, these condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the Company's financial position, results of operations and cash flows for the periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending March 31, 2024.
Use of Estimates	USE OF ESTIMATES The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to current expected credit losses, returns reserve for expected cancellations, fair value of and/or potential impairment of goodwill and value and useful life of long-lived assets (including intangible assets and right-of-use assets), capitalized internal-use software costs, benefit period for deferred commissions, stock-based compensation, incremental borrowing rate used to calculate operating lease liabilities, income and sales tax liabilities, convertible senior notes fair value, litigation, and other contingencies. The Company bases its estimates on known facts and circumstances, historical experience, and various other assumptions. Actual results could differ from those estimates under different assumptions or conditions.
Recently Adopted Accounting Pronouncements/ Recently Issued Accounting Pronouncements Not Yet Adopted	RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS There were no recent accounting pronouncements that were applicable to the Company adopted during the six months ended September 30, 2023. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED Recent accounting pronouncements that may be applicable to the Company are not expected to have a material impact on its present or future financial statements.
Indemnifications	Indemnifications In the normal course of business, the Company may agree to indemnify other parties, including customers, lessors, and parties to other transactions with the Company with respect to certain matters, such as breaches of representations or covenants or intellectual property infringement or other claims made by third parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors. It is not possible to determine the maximum potential amount of the Company's exposure under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on the Company's operating results, financial position, or cash flows. Under some of these agreements, however, the Company's potential indemnification liability may not have a contractual limit.

NET LOSS PER SHARE

6 Months Ended

Sep. 30, 2023

Earnings Per Share [Abstract]

NET LOSS PER SHARE

The following is a reconciliation of the weighted average number of common shares outstanding used in calculating basic and diluted net loss per share (in thousands, except per share data):


	Three Months Ended September 30,				Six Months Ended September 30,
	2023		2022		2023		2022
Net loss	$	(7,452)	$	(11,639)	$	(22,779)	$	(37,682)
Weighted average common shares outstanding - basic and diluted	120,757		116,013		118,778		117,857

Net loss per share - basic and diluted	$	(0.06)	$	(0.10)	$	(0.19)	$	(0.32)

As the Company was in a loss position for all periods presented, basic net loss per share is equivalent to diluted net loss per share for all periods, as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive. The following potentially weighted-average common shares were excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive (shares in thousands):


	Three Months Ended September 30,		Six Months Ended September 30,
	2023	2022	2023	2022
Stock options	601	811	625	787
Restricted stock units and Performance stock units	10,855	15,895	9,878	8,804
Potential shares attributable to the ESPP	1,129	751	626	512

Total anti-dilutive shares	12,585	17,457	11,129	10,103

STOCK-BASED COMPENSATION AND STOCKHOLDERS' EQUITY

6 Months Ended

Sep. 30, 2023

Equity [Abstract]

STOCK-BASED COMPENSATION AND STOCKHOLDERS' EQUITY

The Company accounts for stock-based compensation through the measurement and recognition of compensation expense for share-based payment awards made to employees, directors or consultants over the related requisite service period, including stock appreciation rights, restricted stock, restricted stock units ("RSUs") and performance stock units ("PSUs"), qualified performance-based awards, and stock grants (all issuable under the Company's equity incentive plans).

The Company reserved 8.0 million shares of the Company's common stock for issuance under the 2022 Equity Incentive Plan (the "2022 Plan") plus the number of shares subject to awards that were outstanding under the 2012 Equity Incentive Plan (the "2012 Plan") as of 12:01 a.m. Pacific Time on June 22, 2022 (the “Prior Plan Expiration Time”), to the extent that, after the Prior Plan Expiration Time, such shares would have recycled back to the 2012 Plan in connection with the awards’ expiration, termination, cancellation, forfeiture, or repurchase, as described further below, and in each case, subject to adjustment upon certain changes in the Company’s capitalization. The 2022 Plan provides for the granting of incentive stock options to employees and non-statutory stock options to employees, directors or consultants, and granting of stock appreciation rights, restricted stock, restricted stock units and performance units, qualified performance-based awards, and stock grants. The stock option price of incentive stock options granted cannot be less than the fair market value on the effective date of the grant. Options, restricted stock, and restricted stock units generally vest over three or four years and expire ten years after the grant. As of September 30, 2023, 1,952,177 shares remained available for future grants under the 2022 Plan.

Stock-Based Compensation

The following table presents stock-based compensation expense (in thousands):


	Three Months Ended September 30,				Six Months Ended September 30,

Total	$	14,520	$	24,621	$	32,717	$	52,435

Restricted Stock Units

The following table presents the RSU activity (shares in thousands):


	Number of Shares	Weighted Average Grant Date Fair Value		Weighted Average Remaining Contractual Term (in Years)
Balance as of March 31, 2023	12,993	$	8.56	1.84
Granted	6,497	3.95
Vested and released	(5,318)	8.53
Forfeited	(1,204)	7.30
Balance as of September 30, 2023	12,968	$	6.38	2.06

As of September 30, 2023, there was $56.1 million of total unrecognized compensation cost related to RSUs, which is expected to be recognized over a weighted average of 2.06 years.

Performance Stock Units

PSUs are issued to a group of executives and generally time vest over periods ranging from one to three years from the grant date; vesting is generally also contingent upon achievement of applicable performance metrics or strategic objectives. Vesting of performance-based stock units granted can be tied to our total shareholder return, as measured relative to specified market indices during the applicable performance periods and be contingent upon continued service. The related stock-based compensation expense is recognized over the requisite service period, taking into account the probability that we will satisfy the performance measures or strategic objectives.

The following table presents the PSU activity (shares in thousands):


	Number of Shares	Weighted Average Grant Date Fair Value		Weighted Average Remaining Contractual Term (in Years)
Balance as of March 31, 2023	624	$	11.30	1.45
Granted	2,023	1.23


Forfeited	(116)	21.83
Balance as of September 30, 2023	2,531	2.77		3.12

Total unrecognized compensation cost related to PSUs was $11.5 million as of September 30, 2023, which is expected to be recognized over a weighted average of 3.12 years.

Employee Stock Purchase Plan ("ESPP")

As of September 30, 2023, there was approximately $2.5 million of unrecognized compensation cost related to employee stock purchases. This cost is expected to be recognized over a weighted average period of 0.6 years. In July 2022, the Company added 3.6 million shares to the ESPP for future issuances, and, as of September 30, 2023, a total of 2.4 million shares were available for issuance under the ESPP.

Debt Disclosure [Abstract]

CONVERTIBLE SENIOR NOTES AND TERM LOAN

2024 Notes

As of both September 30, 2023 and March 31, 2023, the Company had $63.3 million aggregate principal amount of 0.50% convertible senior notes due 2024 (the "2024 Notes") in a private placement, including the exercise in full of the initial purchasers' option to purchase additional notes. In August 2022, the Company used the proceeds from the issuance of the Term Loan (as defined below) to fund the cash portion of an exchange of the Company’s approximately $403.8 million aggregate principal amount of the 2024 Notes for cash plus approximately $201.9 million aggregate principal amount of the 2028 Notes (as defined below), and the concurrent repurchase of approximately $60.0 million of the Company’s common stock with the counterparties to such exchange.

The 2024 Notes are senior unsecured obligations of the Company, and interest is payable semiannually in arrears on February 1 and August 1 of each year. The Notes will mature on February 1, 2024, unless earlier repurchased, redeemed, or converted. During the three months ended September 30, 2023, the conditions allowing holders of the 2024 Notes to convert were not met. As of September 30, 2023, the Company was in compliance with all covenants set forth in the indenture governing the 2024 Notes.

The following table presents the net carrying amount and fair value of the liability component of the 2024 Notes (in thousands):

Term Loan and Warrants

As of September 30, 2023 and March 31, 2023, the Company had $225.0 million and $250.0 million, respectively, of principal amount outstanding in a senior secured term loan facility (the “Term Loan”) under a term loan credit agreement (the “Credit Agreement”) entered into on August 3, 2022 with Wilmington Savings Fund Society, FSB, as administrative agent, and certain affiliates of Francisco Partners (“FP”). The Term Loan matures on August 3, 2027 and bears interest at an annual rate equal to the term Standard Overnight Financing Rate ("Term SOFR") (subject to a floor of 1.00% and a credit spread adjustment of 0.10%), plus a margin of 6.50%. As of September 30, 2023, the effective interest rate for the Term Loan was 11.9%.

On May 9, 2023, the Company voluntarily prepaid $25.0 million of principal amount outstanding and $0.2 million of accrued interest on the Term Loan. This payment had no impact on the Company's compliance with the Term Loan covenants. As of September 30, 2023, the Company was in compliance with all covenants set forth in the credit agreement governing the Term Loan.

The obligations under the Credit Agreement will be guaranteed by the Company’s wholly-owned subsidiaries, subject to certain customary exceptions, and secured by a perfected security interest in substantially all of the Company’s tangible and intangible assets, as well as substantially all of the tangible and intangible assets of the guarantors.

In connection with the Credit Agreement, the Company issued detachable warrants (the “Warrants”) to affiliates of FP to purchase an aggregate of 3.1 million shares of the Company’s common stock with a five-year term and an exercise price of $7.15 per share (subject to adjustment) that represents a 27.5% premium over the closing price per share of the Company’s common stock on August 3, 2022. The Warrants are classified as liabilities measured at fair value during each reporting period as the Warrants contain certain terms that could result in cash settlement as a result of events outside of the Company’s control. As of September 30, 2023 and March 31, 2023, the fair value of the Warrants was $3.0 million and $5.5 million, respectively, and was recorded within other liabilities, non-current on the condensed consolidated balance sheets.

2028 Notes

As of September 30, 2023 and March 31, 2023, the Company had $201.9 million aggregate principal amount of 4.00% convertible senior notes due 2028 (the “2028 Notes”), with debt issuance costs of approximately $5.6 million, of which 50% was paid in the form of shares of the Company's common stock.

The 2028 Notes are senior obligations of the Company that accrue interest, payable semi-annually in arrears on February 1 and August 1 of each year. The 2028 Notes will mature on February 1, 2028, unless earlier converted, redeemed or repurchased. As of September 30, 2023, the Company was in compliance with all covenants set forth in the indenture governing the 2028 Notes.

The debt discount and debt issuance costs are amortized to interest expense over the term of the 2028 Notes at an effective interest rate of 4.7%.
