Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Summary of Significant Accounting Policies	Business and Summary of Significant Accounting Policies Description of the Business Appgate, Inc., a Delaware corporation (“Appgate”, the “Company”, “we”, “us”, or “our”), is a cybersecurity company that protects against breaches and fraud through innovative, identity-centric, Zero Trust solutions. Appgate exists to provide modern enterprises with a solution to increasingly common cyber-attacks, against which traditional cybersecurity tools are proving ineffective. We sell and deliver our solutions using a combination of term-based license subscriptions, perpetual licenses and software-as-a-service (“SaaS”), together with related support services. We conduct business worldwide. Our headquarters is in Coral Gables, Florida. Basis of Presentation and Use of Estimates The accompanying unaudited condensed consolidated financial statements have been prepared by our management and reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. The condensed consolidated balance sheet data as of December 31, 2021 and other financial data for the prior period(s) have been derived from our audited consolidated financial statements as of their respective date(s). The condensed consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission (“SEC”) but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”). For further information, refer to our audited consolidated financial statements as of and for the year ended December 31, 2021 included in Amendment No. 1 to our Annual Report on Form 10-K/A for the year ended December 31, 2021 filed with the SEC on December 28, 2022. Results for the interim periods are not necessarily indicative of results to be expected for the entirety of 2022. All references to “$” or “dollars” are to the currency of the United States (“U.S.”) unless otherwise indicated. We operate on a calendar year basis. References to 2021, for example, refer to our year ended December 31, 2021. Risks and Uncertainties due to COVID-19 Pandemic The COVID-19 pandemic continues to evolve and disrupt normal activities in many segments of the U.S. and global economies even as COVID-19 vaccines have been and continue to be administered in 2022. Much uncertainty still surrounds the pandemic, including new variants of COVID-19, its duration and ultimate overall impact on our operations. Management continues to carefully evaluate potential outcomes and has plans to mitigate related risks. While the COVID-19 pandemic did not have a material impact on our business, financial condition or results of operations for 2021 or the nine months ended September 30, 2022, management took measures during such periods to minimize the risks from the pandemic. Those measures were aimed at safeguarding the Company, and the health, safety and well-being of our employees and customers. Liquidity and Going Concern The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to the requirements of the Financial Accounting Standards Board’s (the “FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The Company had cash and cash equivalents and borrowing capacity under the Revolving Credit Facility (as defined in Note 10) of $10.7 million and $12.5 million, respectively, at September 30, 2022, a loss from continuing operations of $66.2 million for the nine months ended September 30, 2022, and an accumulated deficit of $520.8 million at September 30, 2022. Current economic and market conditions have put pressure on our growth plans. The Company’s ability to continue as a going concern is dependent on its ability to obtain additional capital. The Company believes that its current level of cash and cash equivalents and borrowing capacity under the Revolving Credit Facility are not sufficient to continue investing in growth, while at the same time meeting its obligations as they become due. These conditions raise substantial doubt regarding our ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. In an effort to alleviate these conditions, management is currently evaluating various cost reduction and other alternatives and may seek to raise additional funds (in excess of the funds available to the Company under the Revolving Credit Facility) through the issuance of equity, mezzanine or debt securities, through arrangements with strategic partners, through obtaining credit from financial institutions or otherwise. The Company implemented a reduction in force (the “Reduction”) in July 2022 as well as several other cost reduction initiatives, but, as of the date of issuance of these unaudited condensed consolidated financial statements, does not have any additional funding commitment in place. The actual amount that we may be able to raise under these alternatives will depend on market conditions and other factors, as well as limitations under our Note Issuance Agreement and the Revolving Credit Agreement (as defined in Note 10). As we seek additional sources of financing, there can be no assurance that such financing would be available to us on favorable terms or at all. Our ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, our performance and investor sentiment with respect to us and our industry. As a result of these uncertainties, and notwithstanding management’s plans and efforts to date, there is substantial doubt about our ability to continue as a going concern.

(Loss) Income per Common Share

(Loss) Income per Common Share	9 Months Ended
	Sep. 30, 2022
Earnings Per Share [Abstract]
(Loss) Income per Common Share	(Loss) Income per Common Share Basic (loss) income per common share is computed by dividing net (loss) income (the numerator) by the weighted-average number of shares of common stock outstanding (the denominator) for the period. Diluted (loss) income per common share assumes that any dilutive equity instruments were exercised with outstanding common stock adjusted accordingly when the conversion of such instruments would be dilutive. The Company's potential dilutive shares consist of 10,982,805 shares of Appgate’s common stock underlying the Convertible Senior Notes that are convertible at any time at the option of the holders of the Convertible Senior Notes prior to their maturity - see Note 10. These potentially dilutive shares have been excluded from diluted (loss) income per share for the 2021 periods as the effect would be to reduce the net loss per share and have an anti-dilutive effect. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same in the 2021 periods. Weighted average shares of common stock outstanding has been retroactively restated for the equivalent number of shares received by the accounting acquirer as a result of the merger (the “Merger”) of Appgate Cybersecurity, Inc. f/k/a Cyxtera Cybersecurity, Inc. d/b/a AppGate (“Legacy Appgate”) with a direct, wholly owned subsidiary (“Merger Sub”) of Newtown Lane Marketing, Incorporated, a public company incorporated in Delaware (“Newtown” or “Newtown Lane”), which was completed on October 12, 2021, as if these shares had been outstanding as of the beginning of the earliest period presented. The following table summarizes the basic and diluted earnings per share calculations (in thousands, except share and per share amounts). Discontinued operations calculation for the three and nine months ended September 30, 2022 have been omitted as we did not have net income from discontinued operations during those periods.

Related Party Transactions [Abstract]
Transactions With Former Parent - Cyxtera	Transactions with Former Parent – Cyxtera On December 31, 2019, Cyxtera Technologies, Inc. (“Cyxtera” or “former Parent”) consummated several transactions (the “Cyxtera Spin-Off”), following which Legacy Appgate became a stand-alone entity. The transactions separated Cyxtera’s data center business from Legacy Appgate’s cybersecurity business. Over time, Legacy Appgate has entered into several agreements and transactions with Cyxtera (and/or one or more of its subsidiaries), SIS Holdings LP (“SIS Holdings”) and certain equity owners of SIS Holdings. These agreements, relationships and transactions are described below. Service Provider Fee In connection with the formation of Cyxtera in 2017, certain equity owners of SIS Holdings and/or affiliates thereof (collectively, the “Service Providers”) entered into a Services Agreement (the “Services Agreement”) with Cyxtera and all of Cyxtera’s subsidiaries and controlled affiliates as of such date, including Legacy Appgate (collectively, the “Company Group”). Under the Services Agreement, the Service Providers agreed to provide members of the Company Group with certain executive and management, financial, consulting, human resources and advisory services as requested by members of the Company Group from time to time. Pursuant to the Services Agreement, the Company Group also agreed to pay the Service Providers an annual service fee in the aggregate amount of $1.0 million in equal quarterly installments. The Service Providers waived all fees under the Services Agreement for 2021. The Services Agreement was terminated on July 29, 2021. Cyxtera Management Inc. Intercompany Master Services Agreement Fee Also in connection with the formation of Cyxtera in 2017, the Company Group entered into an Intercompany Master Services Agreement (the “Intercompany Master Services Agreement”). Under the Intercompany Master Services Agreement, Cyxtera Management, Inc., a wholly owned subsidiary of Cyxtera (the “Management Company”), agreed to provide certain services to other members of the Company Group from time to time, including financial, accounting, administrative, facilities and other services. No amounts were allocated to Legacy Appgate under the Intercompany Master Services Agreement for 2021. The Intercompany Master Services Agreement was terminated on July 29, 2021. Cyxtera Management Inc. Transition Services Agreement Upon consummation of the Cyxtera Spin-Off, Legacy Appgate and the Management Company entered into a transition services agreement (the “Transition Services Agreement”), pursuant to which the Management Company provided certain transition services to us, and we provided certain transition services to the Management Company. The term under the Transition Services Agreement commenced on January 1, 2020 and ended on June 30, 2021. Substantially all of the obligations under the Transition Services Agreement ceased on December 31, 2020. During each of the three and nine months ended September 30, 2021, the Management Company charged Legacy Appgate $0.1 million of fees for services provided to Legacy Appgate by the Management Company under the Transition Services Agreement. Costs incurred under the Transition Services Agreement are included in general and administrative expenses in the condensed consolidated statement of operations. During the three and nine months ended September 30, 2021, Legacy Appgate charged the Management Company $48 thousand and $0.1 million, respectively, of fees for services provided to the Management Company and its affiliates by Legacy Appgate under the Transition Services Agreement. Income for these services is included in other expenses, net in the condensed consolidated statement of operations. On February 8, 2021, we made a payment of $1.0 million to Cyxtera (and/or its subsidiaries) as settlement in full of trade balances with Cyxtera and its subsidiaries and other amounts due to / from under the Intercompany Master Services Agreement and the Transition Services Agreement, which trade balances and other amounts totaled $2.6 million. Because the Management Company was an affiliate under common control with us at the time of repayment, the settlement of these amounts was recognized as a capital contribution of $1.6 million. Promissory Notes On March 31, 2019, Legacy Appgate issued promissory notes to each of Cyxtera and the Management Company (together, the “Promissory Notes”) evidencing funds borrowed at such time by Legacy Appgate from each of Cyxtera and the Management Company, as well as potential future borrowings. The Promissory Notes had a combined initial aggregate principal amount of $95.2 million and provided for additional borrowings during the term of the Promissory Notes for additional amounts not to exceed approximately $52.5 million in the aggregate (approximately $147.7 million including the initial aggregate principal amount). Interest accrued on the unpaid principal balance of the Promissory Notes at a rate per annum equal to 3%; provided, that with respect to any day during the period from the date of the Promissory Notes through December 31, 2019, interest was calculated assuming that the unpaid principal balance of the Promissory Notes on such day was the unpaid principal amount of the notes on the last calendar day of the quarter in which such day occurs. Interest was payable upon the maturity date of the Promissory Notes. Each of the Promissory Notes had an initial maturity date of March 30, 2020 and was extended through March 30, 2021 by amendments entered into effective as of March 30, 2020. During the nine months ended September 30, 2021, we recognized $0.5 million of interest expense on the Promissory Notes. On February 8, 2021, Legacy Appgate repaid Cyxtera $20.6 million, representing the entirety of the then outstanding principal and interest under the Promissory Note held by Cyxtera, and Legacy Appgate made a partial repayment of $99.0 million to the Management Company on the then outstanding principal and interest of $133.6 million under the Promissory Note held by the Management Company. On that same date, the Management Company issued

Significant Customers No single customer (including, for the avoidance of doubt, resellers and managed service providers) accounted for 10% or more of the total revenue in the periods presented. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. We record an unbilled receivable when revenue is recognized prior to invoicing, or deferred revenue when revenue is recognized after invoicing. For multi-year agreements, we generally invoice customers annually at the beginning of each annual coverage period. We record a receivable related to revenue recognized for multi-year on-premises licenses as we generally have an unconditional right to invoice and receive payment in the future related to those licenses. Contract liabilities consist of deferred revenue and include payments received in advance of performance under a customer contract. Such amounts are recognized as revenue over the remaining contractual period. During the three months ended September 30, 2022 and 2021, we recognized revenue of $3.1 million and $2.8 million, respectively, that was included in the corresponding contract liability balance at the beginning of the related period. During the nine months ended September 30, 2022 and 2021, we recognized revenue of $5.4 million and $6.1 million, respectively, that was included in the corresponding contract liability balance at the beginning of the related period. We receive payments from customers based upon contractual billing schedules and accounts receivable are recorded when the right to consideration becomes unconditional. Payment terms on invoiced amounts are typically 30 days to 45 days. Contract assets include amounts related to our contractual right to consideration for both completed and partially completed performance obligations that may not have been invoiced. Unbilled receivables were $10.3 million and $10.1 million as of September 30, 2022 and December 31, 2021, respectively. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our products and services, not to provide customers with financing. Examples include invoicing at the beginning of a subscription term for SaaS services that do not contain variable consideration with revenue recognized ratably over the contract period, and multi-year on-premises licenses that do not contain variable consideration that are invoiced annually with license revenue recognized upfront and support and maintenance recognized ratably over the contract period.

We did not recognize any impairment losses of deferred contract acquisition costs during the nine months ended September 30, 2022 and 2021. Sales commissions accrued but not paid as of September 30, 2022 and December 31, 2021 totaled $1.0 million and $1.4 million, respectively, and are included within accrued expenses in the condensed consolidated balance sheets. Our fulfillment costs are generally not significant.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	Financial Instruments and Fair Value Measurements Our financial instruments consist of cash equivalents, accounts receivable, accounts payable, accrued expenses, deferred revenue, our debt and an embedded derivative liability. The fair value of cash equivalents, accounts receivable, accounts payable, accrued expenses, deferred revenue, and our Revolving Credit Facility approximate their carrying value because of the short-term nature of these instruments. The carrying value of our Convertible Senior Notes, net of issuance costs, was $73.6 million and $73.0 million as of September 30, 2022 and December 31, 2021, respectively. The fair value of the Convertible Senior Notes was estimated as $61.5 million and $69.5 million as of September 30, 2022 and December 31, 2021, respectively. The fair value was estimated using a discounted cash flow analysis with a yield based on our credit rating. Recurring Fair Value Measurements The fair value of the embedded derivative liability was estimated using a “with and without” approach as of September 30, 2022 and December 31, 2021: • “With” scenario : the fair value of the Convertible Senior Notes as of the valuation date is estimated based on a Two-Factor binomial lattice model. • “Without” scenario : the fair value of the Convertible Senior Notes “without” the embedded features was estimated using a DCF model whereby the contractual cash flows absent the embedded derivative (i.e., the coupon and principal payments) are discounted at a risk-adjusted rate. The following table summarizes fair value measurements by level at September 30, 2022 and December 31, 2021 for instruments measured at fair value on a recurring basis (in thousands): Level 1 Level 2 Level 3 Total September 30, 2022 Financial liability: Embedded derivative liability $ — $ — $ 9,580 $ 9,580 December 31, 2021 Financial liability: Embedded derivative liability $ — $ — $ 78,497 $ 78,497 The following table presents the changes in Level 3 liabilities measured at fair value on a recurring basis during the three and nine months ended September 30, 2022 (in thousands): Embedded derivative liability Total liabilities Balance at January 1, 2022 $ 78,497 $ 78,497 Loss included in earnings 46,143 46,143 Balance as of March 31, 2022 124,640 124,640 Gain included in earnings (92,020) (92,020) Balance as of June 30, 2022 $ 32,620 $ 32,620 Gain included in earnings (23,040) (23,040) Balance as of September 30, 2022 $ 9,580 $ 9,580 The loss/gain included in the previous table is reported in our condensed consolidated statement of operations within change in fair value of embedded derivative liability.

During 2021, we received net proceeds of $72.8 million from the issuance of the Convertible Senior Notes, after deducting fees and expenses of $2.2 million. We recorded these fees and expenses as debt issuance costs that will be amortized over the term of the Convertible Senior Notes. The Convertible Senior Notes are senior, unsecured obligations of Legacy Appgate, and the payment of the principal and interest is unconditionally guaranteed, jointly and severally by Legacy Appgate’s U.S. subsidiaries and, as of the closing of the Merger, also by Appgate. The Convertible Senior Notes will mature on February 9, 2024, unless earlier converted, redeemed, or repurchased. Interest on the Convertible Senior Notes is payable either entirely in cash or entirely in kind (“PIK Interest”), or a combination of cash and PIK Interest at our discretion. The Convertible Senior Notes bear interest at the annual rate of 5% with respect to interest payments made in cash and 5.50% with respect to PIK Interest, with interest payable semi-annually on February 1 and August 1 of each year, commencing on August 1, 2021. Additional notes (“PIK Notes”) to be issued for PIK Interest will have the same terms and conditions as the Convertible Senior Notes. The Note Issuance Agreement includes certain affirmative and financial covenants we are required to satisfy (as further described below). Supplemental Agreement On October 12, 2021, in connection with the closing of the Merger, Newtown entered into a supplemental agreement (the “Supplemental Agreement”) with Legacy Appgate and Magnetar, as representative of the holders of the Convertible Senior Notes, pursuant to which Newtown, among other things, unconditionally guaranteed all of Legacy Appgate’s Obligations under the Note Issuance Agreement, including the Convertible Senior Notes, and assumed all of Legacy Appgate’s Conversion Obligations and Change of Control Conversion Obligations under the Note Issuance Agreement. Amendment to Note Purchase Agreement and Note Issuance Agreement and Waiver to Note Purchase Agreement and Registration Rights Agreement As of February 9, 2022, the Company, Legacy Appgate, the Noteholders and the Representative entered into an Amendment to Note Purchase Agreement and Note Issuance Agreement and Waiver to Note Purchase Agreement and Registration Rights Agreement (the “Amendment and Waiver”). The Amendment and Waiver modifies: (i) the Note Purchase Agreement by (a) (1) extending the date by which the Representative or its affiliates may elect to consummate an Optional Closing (as defined in the Note Purchase Agreement) until the earlier of (x) 75 days after the Company closes a registered offering of equity securities in an aggregate amount of no less than $40.0 million and (y) October 31, 2022 and (2) requiring the Company’s consent to effect any Optional Closing, and (b) waiving, for the period of time set forth in the Amendment and Waiver, certain registration rights of the Noteholders; (ii) the Note Issuance Agreement to provide for the incurrence of certain subordinated indebtedness; and (iii) that certain Registration Rights Agreement, dated as of February 8, 2021 entered into by and among Legacy Appgate and the Noteholders, by waiving, for the period of time set forth in the Amendment and Waiver, certain registration rights of the Noteholders. As of October 14, 2022, the Company, Legacy Appgate, the Noteholders and the Representative entered into an additional Waiver to Note Purchase Agreement and Registration Rights Agreement (the “Second Waiver”) to extend the waiver by the Noteholders of certain registration rights pursuant to the Amendment and Waiver for the additional period set forth in the Second Waiver. Other key terms of the Convertible Senior Notes, as of September 30, 2022, follow: Conversion. Other than upon a Change of Control, prior to maturity, each holder of the Convertible Senior Notes shall have the option to convert all or any portion of such Convertible Senior Notes into Legacy Appgate common stock or, following entry into the Supplemental Agreement, our common stock, subject to and in accordance with the terms of the Note Issuance Agreement, including the applicable conversion rate thereunder. Conversion upon Change of Control. If Legacy Appgate undergoes a Change of Control other than the Merger prior to maturity, each holder of Convertible Senior Notes shall have the option to convert all or any portion of such Convertible Senior Notes into Legacy Appgate common stock or, following entry into the Supplemental Agreement (as defined above), our common stock, subject to and in accordance with the terms of the Note Issuance Agreement, including the applicable conversion rate thereunder. Guarantees; Conversion Obligations. The Convertible Senior Notes are guaranteed by each of Legacy Appgate’s wholly owned domestic subsidiaries and, as of the closing of the Merger, also by Appgate. Upon the consummation of certain events resulting in Legacy Appgate becoming a direct or indirect subsidiary of any person (including the Merger), such acquiring person, any direct or indirect parent company thereof and each subsidiary thereof (immediately prior to such event) shall unconditionally guarantee Legacy Appgate’s Obligations and assume all of Legacy Appgate’s Conversion Obligations and Change of Control Conversion Obligations and, upon such assumption, Legacy Appgate shall be released from its Conversion Obligations and Change of Control Conversion Obligations. Repurchase Upon a Fundamental Change. Upon the occurrence of a Fundamental Change at any time after a Public Company Event, each holder of Convertible Senior Notes shall have the option to require Legacy Appgate to repurchase for cash all or any portion of such Convertible Senior Notes, at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon, subject to and in accordance with the terms of the Note Issuance Agreement. Covenants. The Note Issuance Agreement contains restrictive covenants that, among other things, generally limit the ability of our and certain of our subsidiaries (subject to certain exceptions) to: (i) incur additional debt and issue Disqualified Stock; (ii) create liens; (iii) pay dividends, acquire shares of capital stock, or make investments; (iv) issue guarantees; (v) sell assets and (vi) enter into transactions with affiliates. The Note Issuance Agreement also contains a financial covenant that requires that we maintain liquidity of not less than $10.0 million as of the last day of any calendar month. The foregoing restrictive covenants are subject to a number of important exceptions and qualifications, as set forth in the Note Issuance Agreement. Events of Default. The Note Issuance Agreement provides for customary events of default which include (subject in certain cases to customary grace and cure periods), among others: (i) nonpayment of principal or interest; (ii) breach of covenants or other agreements in the Note Issuance Agreement; (iii) defaults in failure to pay certain other indebtedness; and (iv) certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing under the Note Issuance Agreement, Magnetar or the holders of at least 25% in aggregate principal amount of the Convertible Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on all the Convertible Senior Notes immediately due and payable. No Registration. The Convertible Senior Notes and any Appgate common stock to be issued upon conversion of the Convertible Senior Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and may not be offered or sold in the United States absent registration under the Securities Act or an applicable exemption from registration requirements. This description of the Note Issuance Agreement and the Convertible Senior Notes does not constitute an offer to sell, or the solicitation of an offer to buy, any securities and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale would be unlawful. If the holders have not converted the Convertible Senior Notes and the Convertible Senior Notes have not been redeemed by the maturity date, Legacy Appgate must repay the outstanding principal amount and accrued interest. Embedded Derivative Liability The Convertible Senior Notes contain (i) call options to be settled in cash upon the occurrence of a Change of Control (other than the Merger), (ii) put options to be settled in cash contingent upon the occurrence of a Fundamental Change after a Public Company Event or a Change of Control (other than the Merger) and (iii) a default interest rate increase of 3% applicable upon the occurrence of an event of default. Appgate evaluated these embedded redemption features under the guidance of ASC 815 and determined that a redemption feature contained a substantial premium requiring bifurcation at fair value. However, management determined the probability of a Change of Control to be remote and as such the fair value of the embedded redemption feature has been estimated to be zero. Management also evaluated the contingent interest feature and determined the likelihood of payment to be remote. Accordingly, the fair value of the contingent interest feature was also estimated to be zero. Lastly, management evaluated the embedded conversion feature, and determined that following the closing of the Merger, this embedded feature meets the net settlement criterion under ASC 815-15-25. Consequently, the automatic conversion meets the criteria under ASC 815-15-25-1(c). For an embedded feature to be bifurcated, it must meet all three criteria in ASC 815-15-25-1. Therefore, this embedded feature requires bifurcation. Accordingly, we have recorded an embedded derivative liability representing the combined fair value of the right of the Noteholders to receive 10,982,805 shares of our common stock upon conversion of the Convertible Senior Notes at any time (the “conversion feature”). The embedded derivative liability is presented as a non-current liability in our consolidated balance sheet and is adjusted to reflect fair value at each period end with changes in fair value recorded in the “Change in fair value of embedded derivative liability” financial statement line item of our consolidated statements of operations. We will continue to adjust the embedded derivative liability for changes in fair value until the underlying conversion feature is exercised, redeemed, cancelled or expires. As of September 30, 2022 and December 31, 2021, the carrying amount of this embedded derivative included in our condensed consolidated balance sheets was $9.6 million and $78.5 million, respectively. The fair value of this derivative is estimated using Level 3 inputs in the fair value hierarchy on a recurring basis. Refer to Note 6 – Financial Instruments and Fair Value Measurements . Based on the estimated value of the derivative at September 30, 2022, if the Noteholders were to exercise the conversion feature, they would not receive any excess over the aggregate principal amount on the Convertible Senior Notes.

As of September 30, 2022, no amounts had been drawn on any of these irrevocable stand-by letters of credit. Non-cancelable Purchase Obligations In the normal course of business, we enter into non-cancelable purchase commitments with various parties to purchase products and services, such as technology equipment, subscription-based cloud service arrangements, corporate events and consulting services. As of September 30, 2022 and December 31, 2021, we had outstanding non-cancelable purchase obligations with terms of 12 months or longer aggregating $0.9 million and $2.7 million, respectively. Legal Contingencies We may be subject to legal proceedings and litigation arising from time to time. We record a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. We periodically evaluate developments in our legal matters that could affect the amount of liability that we accrue, if any, and adjust, as appropriate. Until the final resolution of any such matter for which we may be required to record a liability, there may be a loss exposure in excess of the liability recorded and such amount could be significant. We expense legal fees as incurred. As of September 30, 2022 and December 31, 2021, the Company was not a party to, and the Company is not currently party to, any litigation that would have a material adverse effect on the Company’s consolidated financial statements.

On October 12, 2021, our Board of Directors adopted the Appgate, Inc. 2021 Incentive Compensation Plan (the “2021 Plan”).

During 2021, no grants or awards were made under the 2021 Plan. During the three and nine months ended September 30, 2022, our Board of Directors (or a designee thereof) approved certain grants of long-term incentive awards to executives, employees, officers and consultants of the Company (or a subsidiary thereof). Such grants were given as restricted stock units (“RSUs”) and phantom stock units (“PSUs”). Awards of RSUs were given as time-based awards and/or performance-based awards under the 2021 Plan. All PSUs were given as performance-based awards. The vesting of the performance-based awards is dependent upon certain conditions, including service and/or performance conditions as defined in the grants. Our Executive Chairman and Chairman of our Board of Directors received a time-based award, the “Chairman Award”, which entitled him to receive a specific number of shares of the Company’s common stock on the vesting date.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective tax rates for interim periods are based upon the Company’s estimate of the annual effective tax rate. Effective tax rates vary based upon an estimate of taxable earnings and on the mix of taxable earnings in the various states and countries in which we operate. Changes in the annual allocation and apportionment of the Company’s activity amongst these jurisdictions result in changes to the effective rate. The income tax expense of continuing operations for the three and nine months ended September 30, 2022 was $0.8 million and $2.0 million, respectively. The income tax expense of continuing operations for the three and nine months ended September 30, 2022 was different than the amount expected at the statutory federal income tax rate primarily due to foreign withholding taxes, changes in the valuation allowance, the change in the fair value of our embedded derivative liability that is not tax deductible, and state taxes. The Company has determined that the tax effects of the change in the fair value of its embedded derivative liability cannot reliably be estimated. Accordingly, the discrete-period computation method has been used and the annual effective tax rate may change significantly once included. The income tax expense of continuing operations for the three and nine months ended September 30, 2021 was $1.0 million and $2.0 million, respectively. The income tax expense on the pre-tax loss for the three and nine months ended September 30, 2021 was different than the amount expected at the statutory federal income tax rate primarily due to foreign withholding taxes.

Revolving Credit Agreement As of January 9, 2023, we had an aggregate of $46.5 million in borrowings outstanding under the Revolving Credit Facility and were in non-compliance with one of the debt covenants under the Revolving Credit Facility due to our failure to deliver our Quarterly Report on Form 10-Q for the quarter ended September 30, 2022 to SIS Holdings within 15 days after the date such Form 10-Q was required to be filed with the SEC.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation and Use of Estimates
Use of Estimates	All references to “$” or “dollars” are to the currency of the United States (“U.S.”) unless otherwise indicated. We operate on a calendar year basis. References to 2021, for example, refer to our year ended December 31, 2021.
Liquidity and Going Concern	Liquidity and Going Concern The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to the requirements of the Financial Accounting Standards Board’s (the “FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The Company had cash and cash equivalents and borrowing capacity under the Revolving Credit Facility (as defined in Note 10) of $10.7 million and $12.5 million, respectively, at September 30, 2022, a loss from continuing operations of $66.2 million for the nine months ended September 30, 2022, and an accumulated deficit of $520.8 million at September 30, 2022. Current economic and market conditions have put pressure on our growth plans. The Company’s ability to continue as a going concern is dependent on its ability to obtain additional capital. The Company believes that its current level of cash and cash equivalents and borrowing capacity under the Revolving Credit Facility are not sufficient to continue investing in growth, while at the same time meeting its obligations as they become due. These conditions raise substantial doubt regarding our ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. In an effort to alleviate these conditions, management is currently evaluating various cost reduction and other alternatives and may seek to raise additional funds (in excess of the funds available to the Company under the Revolving Credit Facility) through the issuance of equity, mezzanine or debt securities, through arrangements with strategic partners, through obtaining credit from financial institutions or otherwise. The Company implemented a reduction in force (the “Reduction”) in July 2022 as well as several other cost reduction initiatives, but, as of the date of issuance of these unaudited condensed consolidated financial statements, does not have any additional funding commitment in place. The actual amount that we may be able to raise under these alternatives will depend on market conditions and other factors, as well as limitations under our Note Issuance Agreement and the Revolving Credit Agreement (as defined in Note 10). As we seek additional sources of financing, there can be no assurance that such financing would be available to us on favorable terms or at all. Our ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, our performance and investor sentiment with respect to us and our industry. As a result of these uncertainties, and notwithstanding management’s plans and efforts to date, there is substantial doubt about our ability to continue as a going concern.
