Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains "forward-looking statements" within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, which are subject to a number of risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding our future expenses, results of operations and financial position, integration activities, expected impacts of the ongoing COVID-19 pandemic, beliefs about our business strategy, expected benefits from our acquisition of ECI Telecom Group Ltd. ("ECI) and the sale of our Kandy Communications business, plans and objectives of management for future operations, plans for future cost reductions, if any, restructuring activities, and plans for future product offerings, development and manufacturing are forward-looking statements. Without limiting the foregoing, the words "anticipates", "believes", "could", "estimates", "expects", "intends", "may", "plans", "seeks" and other similar language, whether in the negative or affirmative, are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are unknown and/or difficult to predict and that may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements. Such risks and uncertainties include, but are not limited to, risks related to the ongoing COVID-19 pandemic on the global economy and financial markets as well as on the Company, our customers and suppliers, which may impact our sales, gross margin, customer demand and our ability to supply our products to our customers; failure to realize anticipated benefits of our acquisition of ECI; failure to achieve the expected benefits from the sale of our Kandy Communications business; supply chain disruptions resulting from component availability and/or geopolitical instabilities and disputes; unpredictable fluctuations in quarterly revenue and operating results; risks related to cybersecurity and data intrusion; failure to compete successfully against telecommunications equipment and networking companies; failure to grow our customer base or generate recurring business from our existing customers; credit risks; the timing of customer purchasing decisions and our recognition of revenues; economic conditions; the impact of restructuring and cost-containment activities; litigation; market acceptance of our products and services; rapid technological and market change; our ability to protect our intellectual property rights and obtain necessary licenses; our ability to maintain partner, reseller, distribution and vendor support and supply relationships; the potential for defects in our products; risks related to the terms of our credit agreement; higher risks in international operations and markets; increases in tariffs, trade restrictions or taxes on our products; currency fluctuations; and/or failure or circumvention of our controls and procedures. We therefore caution you against relying on any of these forward-looking statements.

Additional important factors that could cause actual results to differ materially from those in these forward-looking statements are also discussed in Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Quarterly Report on Form 10-Q and Part I, Item 1A and Part II, Item 7A, "Risk Factors" and "Quantitative and Qualitative Disclosures About Market Risk," respectively, of our Annual Report on Form 10-K for the year ended December 31, 2020. Any forward-looking statement made by us in this Quarterly Report on Form 10-Q speaks only as of the date on which this Quarterly Report on Form 10-Q was first filed. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise.

(1) BASIS OF PRESENTATION

Business

Ribbon Communications Inc. ("Ribbon" or the "Company") is a leading global provider of communications technology to service providers and enterprises. The Company provides a broad range of software and high-performance hardware products, solutions and services that enable the secure delivery of data and voice communications for residential consumers and for small, medium, and large enterprises and industry verticals such as finance, education, government, utilities and transportation. Ribbon's mission is to create a recognized global technology leader providing cloud-centric solutions that enable the secure exchange of information, with unparalleled scale, performance and elasticity. The Company is headquartered in Plano, Texas, and has a global presence with research and development, or sales and support locations in over thirty-five countries around the world.

Basis of Presentation

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring items, necessary for their fair presentation with accounting principles generally accepted in the United States of America ("GAAP") and with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC").

On December 1, 2020 (the "Kandy Sale Date"), American Virtual Cloud Technologies, Inc. ("AVCT") completed the purchase of the Company's cloud-based enterprise service business (the "Kandy Communications Business") and accordingly, the revenue and expenses of the Kandy Communications Business are excluded from the Company's condensed consolidated financial statements for the three months ended March 31, 2021.

On March 3, 2020 (the "ECI Acquisition Date"), a subsidiary of the Company merged with ECI Telecom Group Ltd ("ECI") (the "ECI Acquisition"). The financial results of ECI are included in the Company's condensed consolidated financial statements for the period subsequent to the ECI Acquisition Date.

Interim results are not necessarily indicative of results for a full year or any future interim period. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (the "Annual Report"), which was filed with the SEC on February 26, 2021.

Operating Segments

The Company's chief operating decision maker (the "CODM") is its President and Chief Executive Officer. Effective in the fourth quarter of 2020 and in connection with the ECI Acquisition, the CODM began to assess the Company's performance based on the performance of two separate organizations within Ribbon: the Cloud and Edge segment ("Cloud and Edge") and the IP Optical Networks segment ("IP Optical Networks"). Financial information for the IP Optical Networks segment included in the Company's financial results for the three months ended March 31, 2020 is for the period subsequent to the ECI Acquisition Date through March 31, 2020.

Reclassifications

In the fourth quarter of 2020, the Company reclassified amounts recorded for amortization of acquired intangible assets in prior presentations from Cost of revenue - product and Sales and marketing to a separate line included in operating expenses in the condensed consolidated statements of operations, as management believes this presentation enhances the comparability of the Company's financial statements with industry peers. These reclassifications also did not impact the condensed consolidated balance sheets or statements of cash flows for any historical periods. The Company did not reclassify depreciation of property and equipment related to production activities from cost of revenue to other accounts.

Significant Accounting Policies

The Company's significant accounting policies are disclosed in Note 2 to the Consolidated Financial Statements included in the Annual Report. There were no material changes to the significant accounting policies during the three months ended March 31, 2021.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Ribbon and its wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates and Judgments

The preparation of financial statements in conformity with GAAP requires Ribbon 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 financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant estimates and judgments relied upon in preparing these condensed consolidated financial statements include accounting for business combinations, revenue recognition for multiple element arrangements, inventory valuations, assumptions used to determine the fair value of stock-based compensation, intangible asset and goodwill valuations, including impairments, legal contingencies and recoverability of Ribbon's net deferred tax assets and the related valuation allowances. Ribbon regularly assesses these estimates and records changes in estimates in the period in which they become known. Ribbon bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Restricted Cash

The Company classifies as restricted cash all cash pledged as collateral to secure long-term obligations and all cash whose use is otherwise limited by contractual provisions.

At March 31, 2021, the Company had $2.7 million of restricted cash, representing restricted short-term bank deposits pledged to secure certain performance and financial bonds as security for the Company's obligations under tenders, contracts and to one of its main subcontractors.

At December 31, 2020, the Company had $7.3 million of restricted cash, comprised of $4.6 million restricted in connection with a tax payment on certain fixed assets formerly held by ECI that were sold in connection with the ECI Acquisition, and $2.7 million of restricted short-term bank deposits pledged to secure certain performance and financial bonds as security for the Company's obligations under tenders, contracts and to one of its main subcontractors.

Transfers of Financial Assets

The Company maintains customer receivables factoring agreements with a number of financial institutions primarily for IP Optical Networks sales outside of the United States. Under the terms of these agreements, the Company may transfer receivables to the financial institutions, on a non-recourse basis, provided that the financial institutions approve the receivables in advance. The Company maintains credit insurance policies from major insurance providers or obtains letters of credit from the customers for a majority of its factored trade receivables. The Company accounts for the factoring of its financial assets as a sale of the assets and records the factoring fees, when incurred, as a component of interest expense in the condensed consolidated statements of operations, and the proceeds from the sales of receivables are included in cash from operating activities in the condensed consolidated statements of cash flows. During the three months ended March 31, 2021, the Company received $31.1 million of cash from the sale of certain accounts receivable and recorded $0.2 million of interest expense in connection with these transactions. During the three months ended March 31, 2020, the Company received $15.1 million of cash from the sale of certain accounts receivable and recorded $0.1 million of interest expense in connection with these transactions.

Fair Value of Financial Instruments and Fair Value Hierarchy

The carrying amounts of the Company's financial instruments approximate their fair values and include cash equivalents, accounts receivable, borrowings under a revolving credit facility, accounts payable and long-term debt.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. The three-tier fair value hierarchy is based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1. Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2. Level 2 applies to assets or liabilities for which there are inputs that are directly or indirectly observable in the marketplace, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets).

Level 3. Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

Recent Accounting Pronouncements

The Financial Accounting Standards Board ("FASB") issued the following accounting pronouncement which became effective for the Company in 2021, and which did not have a material impact on its condensed consolidated financial statements:

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"), which modifies ASC 740 to simplify the accounting for income taxes. ASU 2019-12 addresses the accounting for hybrid tax regimes, tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of legal entities not subject to tax, intraperiod tax allocation exception to incremental approach, ownership changes in investments - changes from a subsidiary to an equity method investment, ownership changes in investments - changes from an equity method investment to a subsidiary, interim period accounting for enacted changes in tax law and year-to-date loss limitation in interim period tax accounting.

The FASB issued the following accounting pronouncement, which the Company does not believe will have a material impact on its condensed consolidated financial statements upon adoption:

In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope ("ASU 2021-01"), which refines the scope of Accounting Standards Codification 848, Reference Rate Reform ("ASC 848") and clarifies some of its guidance as part of the FASB's monitoring of global reference rate reform activities. ASU 2021-01 permits entities to elect certain optional expedients and exceptions when accounting for derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, for computing variation margin settlements, and for calculating price alignment interest in connection with reference rate reform activities under way in global financial markets (the "discounting transition"). ASU 2021-01 is effective for the Company prospectively in any period through December 31, 2022 that a modification is made to the terms of the derivatives affected by the discounting transition.


(2) ACQUISITION OF ECI

On the ECI Acquisition Date, Ribbon completed its previously announced merger transaction with ECI in accordance with the terms of the Agreement and Plan of Merger, dated as of November 14, 2019, by and among Ribbon, ECI, an indirect wholly-owned subsidiary of Ribbon ("Merger Sub"), Ribbon Communications Israel Ltd. and ECI Holding (Hungary) kft, pursuant to which Merger Sub merged with and into ECI, with ECI surviving such merger as a wholly-owned subsidiary of Ribbon. Prior to the ECI Acquisition Date, ECI was a privately-held global provider of end-to-end packet-optical transport and software-defined networking ("SDN") and network function virtualization ("NFV") solutions for service providers, enterprises and data center operators.

As consideration for the ECI Acquisition, Ribbon issued the ECI shareholders and certain others 32.5 million shares of Ribbon common stock with a fair value of $108.6 million (the "Stock Consideration") and paid $322.5 million of cash (the "Cash Consideration"), comprised of $183.3 million to repay ECI's outstanding debt, including both principal and interest, and $139.2 million paid to ECI's selling shareholders. In addition, ECI shareholders received $33.4 million from the sale of certain of ECI's real estate assets. Cash Consideration was financed through cash on hand and committed debt financing consisting of a new $400 million term loan facility and new $100 million revolving credit facility, which was undrawn at the ECI Acquisition Date.

The ECI Acquisition has been accounted for as a business combination and the financial results of ECI have been included in the Company's condensed consolidated financial statements for the periods subsequent to the ECI Acquisition. The Company's financial results for the three months ended March 31, 2020 include $30.0 million of revenue and $3.3 million of net loss attributable to ECI.

The Company finalized the valuation of acquired assets, identifiable intangible assets and certain assumed liabilities in the fourth quarter of 2020. A summary of the allocation of the purchase consideration for ECI is as follows (in thousands):

  Deferred revenue, net of current(3,726)

  Other long-term liabilities(46,117)
$455,402 

The valuation of the acquired intangible assets is inherently subjective and relies on significant unobservable inputs. The Company used an income approach to value the acquired in-process research and development, developed technology, customer relationships and trade name intangible assets. The valuation for each of these intangible assets was based on estimated projections of expected cash flows to be generated by the assets, discounted to the present value at discount rates commensurate with perceived risk. The valuation assumptions take into consideration the Company's estimates of customer attrition, technology obsolescence and revenue growth projections. The Company is amortizing the identifiable intangible assets arising from the ECI Acquisition in relation to the expected cash flows from the individual intangible assets over their respective useful lives, which have a weighted average life of 12.38 years (see Note 6). Goodwill results from assets that are not separately identifiable as part of the transaction and is not deductible for tax purposes.

Pro Forma Results

The following unaudited pro forma information presents the condensed combined results of operations of Ribbon and ECI for the three months ended March 31, 2020 as if the ECI Acquisition had been completed on January 1, 2019, with adjustments to give effect to pro forma events that are directly attributable to the ECI Acquisition. These pro forma adjustments include an increase in research and development expense related to the conformance of ECI's cost capitalization policy to Ribbon's, additional amortization expense for the acquired identifiable intangible assets, a decrease in historical ECI interest expense reflecting the extinguishment of certain of ECI's debt as a result of the ECI Acquisition, and an increase in interest expense reflecting the new debt entered into by the Company in connection with the ECI Acquisition. Pro forma adjustments also include the elimination of acquisition-, disposal- and integration-related expenses directly attributable to the acquisition from the three months ended March 31, 2020 and inclusion of such costs in the same prior year period.

The unaudited pro forma results do not reflect any operating efficiencies or potential cost savings that may result from the consolidation of the operations of Ribbon and ECI. Accordingly, these unaudited pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the combined company that

Acquisition-, Disposal- and Integration-Related Expenses

Acquisition-related expenses include those expenses related to acquisitions that would otherwise not have been incurred by the Company, including professional and services fees, such as legal, audit, consulting, paying agent and other fees. Disposal-related expenses are professional and services fees related to disposals of subsidiaries or portions of the business. Integration-related expenses represent incremental costs related to combining the Company and its business acquisitions, such as third-party consulting and other third-party services related to merging the previously separate companies' systems and processes.

The disposal-related expenses in the three months ended March 31, 2021 relate to the Kandy Sale (as defined below). The acquisition-related expenses in the three months ended March 31, 2020 primarily relate to the ECI Acquisition.

The Company's acquisition-, disposal- and integration-related expenses for the three months ended March 31, 2021 and 2020 were as follows (in thousands):

(3) SALE OF KANDY COMMUNICATIONS BUSINESS

On August 5, 2020, the Company announced that it had entered into a definitive agreement (as amended, the "Kandy Purchase Agreement") with AVCT to sell the Kandy Communications Business. Under the Kandy Purchase Agreement, AVCT agreed to purchase the assets and assume certain liabilities associated with the Kandy Communications Business, as well as all of the outstanding interests in Kandy Communications LLC, a subsidiary of the Company (the "Kandy Sale").

On December 1, 2020, the Company completed the Kandy Sale. The assets acquired and liabilities assumed by AVCT in connection with the Kandy Sale were primarily comprised of accounts receivable, property and equipment, trade accounts payable and employee-related accruals. As sale consideration, AVCT paid Ribbon $45.0 million, subject to certain adjustments, in the form of units of AVCT's securities (the "AVCT Units"), with each AVCT Unit consisting of: $1,000 in principal amount of AVCT’s Series A-1 convertible debentures (the “Debentures”); and (ii) one warrant to purchase 100 shares of AVCT common stock, $0.0001 par value (the “Warrants”), as consideration for the Kandy Sale. The Company received 43,778 AVCT Units as sale consideration on the Kandy Sale Date.

The Debentures bear interest at a rate of 10% per annum, which will be added to the principal amount of the Debentures, except upon maturity, in which case accrued and unpaid interest is payable in cash. The entire principal of each Debenture, together with accrued and unpaid interest thereon, is due and payable on the earlier of the May 1, 2023 maturity date or the occurrence of a Change in Control as defined in the Kandy Purchase Agreement. Each Debenture is convertible, in whole or in part, at any time at the Company's option into that number of shares of AVCT common stock, calculated by dividing the principal amount being converted, together with all accrued and unpaid interest thereon, by the applicable conversion price, initially $3.45. The Debentures are subject to mandatory redemption if the AVCT stock price is at or above $6.00 per share for 40 trading days in any 60 consecutive trading day period, subject to the satisfaction of certain other conditions. The conversion

price is subject to customary adjustments including, but not limited to, stock dividends, stock splits and reclassifications. At the Company's option, up to $5.0 million of the Debentures may be redeemed by AVCT at par in the event AVCT raises at least $50.0 million in its offering of AVCT Units. As of February 19, 2021, the stock price had traded above $6.00 for 40 days within a 60 consecutive trading day period, and accordingly, the Debentures will be converted to shares of AVCT common stock upon the completion of customary regulatory filings by AVCT.

The Warrants are independent of the Debentures and entitle the Company to purchase 4,377,800 shares of AVCT common stock at an exercise price of $0.01 per share. The Warrants expire on December 1, 2025, and were immediately exercisable on the Kandy Sale Date.

The Company had not redeemed any of the Debentures or exercised any of the Warrants as of March 31, 2021. The Company is also subject to a lock-up provision which limits the Company's ability to sell any shares of AVCT common stock underlying the Debentures and the Warrants prior to June 1, 2021, except in certain transactions.

The Company determined that the AVCT Units had a fair value of $84.9 million at the Kandy Sale Date, comprised of the Debentures with a fair value of $66.3 million and the Warrants with a fair value of $18.6 million. The value of the net assets sold to AVCT totaled $1.3 million, resulting in a gain on the sale of $83.6 million.

The Company calculated the fair value of the Debentures using a Lattice-based valuation approach, which utilizes a binomial tree to model the different paths the price of AVCT's common stock might take over the Debentures' life by using assumptions regarding the stock price volatility and risk-free interest rate. These results are then used to calculate the fair value of the Debentures at each measurement date. The Company uses the Black-Scholes valuation model for estimating the fair value of the Warrants at each measurement date. The fair value of the Warrants is affected by AVCT's stock price as well as valuation assumptions, including the volatility of AVCT's stock price, expected term of the option, risk-free interest rate and expected dividends. Both the Lattice and Black-Scholes valuation models are based on available market data, giving consideration to all of the rights and obligations of each instrument and precluding the use of "blockage" discounts or premiums in determining the fair value of a large block of financial instruments.

The Company is calculating the fair value of the Debentures and Warrants at each quarter-end and recording any adjustments to the fair values in Other expense, net. At March 31, 2021 and December 31, 2020, the aggregate fair value of the Debentures and Warrants was $92.7 million and $115.2 million, respectively. The Company recorded the loss of $23.9 million arising from the decrease in the fair value of the Debentures and Warrants from January 1, 2021 to March 31, 2021 in Other expense, net, in its condensed consolidated statement of operations for the three months ended March 31, 2021. The loss was partially offset by $1.5 million of interest which was added to the principal of the Debentures. The interest is included in Interest (expense) income, net, in the condensed consolidated statement of operations for the three months ended March 31, 2021. The fair values of the Debentures and Warrants are reported as Investments in the Company's condensed consolidated balance sheets at March 31, 2021 and December 31, 2020 and are classified as Level 2 fair value measurements within the fair value hierarchy (see Note 1).


(4) EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding during the period. For periods in which the Company reports net income, diluted net earnings per share is determined by using the weighted average number of common and dilutive common equivalent shares outstanding during the period unless the effect is antidilutive.

The calculations of shares used to compute earnings (loss) per share were as follows (in thousands):

(9) RESTRUCTURING AND FACILITIES CONSOLIDATION INITIATIVES

The Company recorded restructuring and related expense aggregating $6.0 million and $2.1 million in the three months ended March 31, 2021 and 2020, respectively. Restructuring and related expense includes both restructuring expense for severance and related costs and facilities-related costs, primarily comprised estimated future variable lease costs for vacated properties with no intent or ability of sublease, and accelerated rent amortization expense.

For restructuring events that involve lease assets and liabilities, the Company applies lease reassessment and modification guidance and evaluates the right-of-use assets for potential impairment. If the Company plans to exit all or distinct portions of a facility and does not have the ability or intent to sublease, the Company will accelerate the amortization of each of those lease components through the vacate date. The accelerated amortization is recorded as a component of Restructuring and related expense in the Company's condensed consolidated statements of operations. Related variable lease expenses will continue to be expensed as incurred through the vacate date, at which time the Company will reassess the liability balance to ensure it appropriately reflects the remaining liability associated with the premises and record a liability for the estimated future variable lease costs.

The components of Restructuring and related expense for the three months ended March 31, 2021 and 2020 were as follows (in thousands):

Accelerated amortization of lease assets due to cease-use3,368 70 
$5,950 $2,075 

Accelerated Rent Amortization

Accelerated rent amortization is recognized from the date that the Company commences the plan to fully or partially vacate a facility, for which there is no intent or ability to enter into a sublease, through the final vacate date. The accelerated rent amortization recorded in connection with the Facilities Initiative reduced the value of the Company's Operating lease right-of-use assets recorded in the Company's condensed consolidated balance sheets at March 31, 2021 and December 31, 2020, respectively. The liability for the total lease payments for each respective facility is included as a component of Operating lease liabilities in the Company's condensed consolidated balance sheets, both current and noncurrent (see Note 17). The Company may incur additional future expense if it is unable to sublease other locations included in its restructuring initiatives.

2020 Restructuring Initiative

In 2020, the Company implemented a restructuring plan to eliminate certain positions and redundant facilities, primarily in connection with the ECI Acquisition, to further streamline the Company's global footprint and improve its operations (the "2020 Restructuring Initiative"). In connection with this initiative, the Company expects to eliminate duplicate functions arising from the ECI Acquisition and support its efforts to integrate the two companies.

The Company recorded restructuring and related expense of $0.4 million and $1.1 million in connection with the 2020 Restructuring Initiative in the three months ended March 31, 2021 and 2020, respectively. The amount recorded in the three months ended March 31, 2021 was comprised of $0.7 million for severance and related costs for approximately 10 employees and $0.4 million of expense for variable costs related to restructured facilities, offset by a credit of $0.7 million for changes in estimate related to amounts previously recorded. The amount recorded in the three months ended March 31, 2020 was for severance for three former executives of ECI. The Company expects the amounts related to severance will be paid in 2021. The Company expects that it will record additional restructuring and related expense approximating $4 million under the 2020 Restructuring Initiative in the aggregate for severance and planned facility consolidations. A summary of the 2020 Restructuring Initiative accrual activity for severance and related costs for the three months ended March 31, 2021 is as follows (in thousands):

2019 Restructuring and Facilities Consolidation Initiative

In June 2019, the Company implemented a restructuring plan to further streamline the Company's global footprint, improve its operations and enhance its customer delivery (the "2019 Restructuring Initiative"). The 2019 Restructuring Initiative includes facility consolidations, refinement of the Company's research and development activities, and a reduction in workforce. The facility consolidations under the 2019 Restructuring Initiative (the "Facilities Initiative") include a consolidation of the Company's North Texas sites into a single campus, housing engineering, customer training and support, and administrative functions, as well as a reduction or elimination of certain excess and duplicative facilities worldwide. In addition, the Company is substantially consolidating its global software laboratories and server farms into two lower cost North American sites. The Company continues to evaluate its properties included in the Facilities Initiative for accelerated amortization and/or right-of-use asset impairment. The Company expects that the actions under the Facilities Initiative will be completed in 2021.

In connection with the 2019 Restructuring Initiative, the Company recorded restructuring and related expense of $5.6 million and $1.0 million in the three months ended March 31, 2021 and 2020, respectively. The amount recorded in the three months ended March 31, 2021 related to facilities, including $3.4 million of accelerated amortization of lease assets. The amount recorded in the three months ended March 31, 2020 was comprised of $0.7 million for severance and related costs for five employees and $0.3 million related to facilities. The Company expects that the entire amount accrued for severance and related costs will be paid in 2021. The Company estimates that it will record nominal, if any, additional restructuring and related expense related to severance and related costs under the 2019 Restructuring Initiative.

A summary of the 2019 Restructuring Initiative accrual activity for the three months ended March 31, 2021 is as follows (in thousands):

(10) DEBT

2020 Credit Facility

On March 3, 2020, the Company entered into a Senior Secured Credit Facilities Credit Agreement (as amended, the "2020 Credit Facility"), by and among the Company, as a guarantor, Ribbon Communications Operating Company, Inc., as the borrower ("Borrower"), Citizens Bank, N.A. ("Citizens"), as administrative agent, a lender, issuing lender, swingline lender, joint lead arranger and bookrunner, Santander Bank, N.A., as a lender, joint lead arranger and bookrunner, and the other lenders party thereto (each, together with Citizens Bank, N.A. and Santander Bank, N.A., referred to individually as a "Lender", and collectively, the "Lenders"). The proceeds of the 2020 Credit Facility were used, in part, to pay off in full all obligations of the Company under its prior credit facility (the "2019 Credit Facility").

The 2020 Credit Facility provides for $500 million of commitments from the lenders to the Borrower, comprised of $400 million in term loans (the "2020 Term Loan Facility") and a $100 million facility available for revolving loans (the "2020 Revolving Credit Facility"). Under the 2020 Revolving Credit Facility, a $30 million sublimit is available for letters of credit and a $20 million sublimit is available for swingline loans. Under the 2020 Credit Facility, the Company was originally required to make quarterly principal payments aggregating approximately $10 million in the first year, $20 million per year for the following three years, and $30 million in the last year, with the remaining balance due on the maturity date. The 2020 Credit Facility also requires periodic interest payments until maturity.

The indebtedness and other obligations under the 2020 Credit Facility are unconditionally guaranteed on a senior secured basis by the Company, Edgewater Networks, Inc., a wholly-owned subsidiary of the Company, and GENBAND Inc., a wholly-owned subsidiary of the Company (together, the "Guarantors"). The facilities under the 2020 Credit Facility are secured by first-priority liens on substantially all of the assets of the Borrower and the Guarantors, including substantially all of the assets of the Company.

The 2020 Credit Facility requires compliance with certain financial covenants, including a minimum Consolidated Fixed Charge Coverage Ratio and a maximum Consolidated Net Leverage Ratio (each as defined in the 2020 Credit Facility, and each tested on a quarterly basis).

In addition, the 2020 Credit Facility contains various covenants that, among other restrictions, limit the Company’s and its subsidiaries’ ability to incur or assume indebtedness; grant or assume liens; make acquisitions or engage in mergers; sell, transfer, assign or convey assets; repurchase equity and make dividend and certain other restricted payments; make investments; engage in transactions with affiliates; enter into sale and leaseback transactions; enter into burdensome agreements; change the nature of its business; modify their organizational documents; and amend or make prepayments on certain junior debt.

The 2020 Credit Facility contains events of default that are customary for a secured credit facility. If an event of default relating to bankruptcy or other insolvency events with respect to the Company or any of its subsidiaries occurs, all obligations under the 2020 Credit Facility will immediately become due and payable. If any other event of default occurs under the 2020 Credit Facility, the lenders may accelerate the maturity of the obligations outstanding under the Credit Facility and exercise other rights and remedies, including charging a default rate of interest equal to 2.00% per year above the rate that would otherwise be applicable. In addition, if any event of default exists under the 2020 Credit Facility, the lenders can commence foreclosure or other actions against the collateral.

On August 18, 2020 (the "First Amendment Effective Date"), the Borrower entered into a First Amendment to the 2020 Credit Facility (the "First Amendment"). Pursuant to an assignment and assumption agreement entered into by Citizens and certain affiliates of Whitehorse Capital on the First Amendment Effective Date (collectively, "HIG Whitehorse"), and consented to by Citizens and the Borrower, $75 million of the 2020 Term Loan Facility, designated as the Term B Loan (the "Term B Loan"), was assigned from Citizens to HIG Whitehorse. The remaining $325 million of the 2020 Term Loan Facility that was not assigned to HIG Whitehorse was deemed the Term A Loan (the "Term A Loan" and, together with the Term B Loan, the "Amended 2020 Term Loan Facility").

The Term A Loan and the 2020 Revolving Credit Facility mature in March 2025. The Term A Loan and 2020 Revolving Credit Facility bear interest at the Borrower's option at either the LIBOR rate plus a margin ranging from 1.50% to 3.50% per year, or the base rate (the highest of the Federal Funds Effective Rate (as defined in the 2020 Credit Facility) plus 0.50%, or the prime rate announced from time to time in The Wall Street Journal) plus a margin ranging from 0.50% to 2.50% per year (the "Applicable Margin"). The Applicable Margin varies depending on the Company's Consolidated Net Leverage Ratio (as defined in the 2020 Credit Agreement). The base rate and the LIBOR rate are each subject to a zero percent floor. The Company was required to make quarterly principal payments on the Term A Loan aggregating approximately $10 million in the first year, $16 million per year in each of the next two years, $20 million in the fourth year and $16 million in the last year, with the final payment approximating $244 million due on the maturity date. The Borrower could prepay all amounts under the Term A Loan and the 2020 Revolving Credit Facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements.

The Term B Loan was scheduled to mature in March 2026 and bore interest, at the Borrower's option, at either the LIBOR rate plus a margin of 7.50% per year, or the base rate (the highest of the Federal Funds Effective Rate (as defined in the First Amendment) plus 0.50%, or the prime rate announced from time to time in The Wall Street Journal, plus a margin of 6.50% per year. The Term B Loan had a lower rate of amortization than the Term A Loan and was subject to a 1.0% premium if voluntarily repaid in connection with a repricing transaction (as defined in the 2020 Credit Facility) occurring prior to the six month anniversary of the First Amendment Effective Date. The Company was required to make quarterly principal payments totaling approximately $1 million in the first year and $8 million in the aggregate over the next four and a half years, with the final payment approximating $66 million.

The First Amendment reduced the Borrower's ability to incur new tranches of term loans, or increases in commitments under the Amended 2020 Term Loan Facility or the 2020 Revolving Credit Facility. Specifically, such indebtedness could be incurred up to an aggregate dollar amount equal to 75% of the Company's Consolidated Adjusted EBITDA (as defined in the 2020 Credit Facility), reduced from 100% prior to the First Amendment, as of the most recently ended fiscal quarter for which financial statements had been delivered to the lenders, plus additional amounts, so long as the Borrower's Consolidated Net Leverage Ratio (as defined in the 2020 Credit Agreement) did not exceed 2.25:1.00, reduced from 2.75:1.00 under the 2020 Credit Agreement. The First Amendment also reduced the amount of Unrestricted Cash (as defined in the 2020 Credit Agreement) used in calculating the Borrower's Consolidated Net Leverage Ratio from $25 million to $10 million.

On December 1, 2020, the Borrower entered into a Second Amendment to the 2020 Credit Facility to obtain consent for an equity exchange with AVCT in connection with the Kandy Sale, as well as to amend certain other provisions of the 2020 Credit Facility.

At December 31, 2020, the Company had an outstanding Term A Loan balance of $318.5 million at an average interest rate of 3.4%, and an outstanding Term B Loan balance of $74.6 million at an average interest rate of 8.4%. The 2020 Revolving Credit Facility did not have an outstanding balance but had $5.6 million of letters of credit outstanding with an interest rate of 2.5%.

On March 3, 2021 (the "Third Amendment Effective Date"), the Company, the Borrower and certain of its subsidiaries entered into a Third Amendment to Credit Agreement (the "Third Amendment"), which further amends the 2020 Credit Facility. The Third Amendment provided for an incremental term loan facility to the Borrower in the original principal amount of $74.6 million, the proceeds of which were used on the Third Amendment Effective Date to consummate an open market purchase of all outstanding amounts under the Term B Loan. Upon the consummation of the open market purchase, the Term B Loans were assigned to the Borrower and immediately cancelled, such that the outstanding amount under the Term A Loan and incremental term loan facility were combined and held by the Lenders (the "2020 Term Loan") with the same terms as the Term A Loan. The Company wrote off $2.5 million of capitalized debt issuance costs in connection with the Third Amendment, which is included in Interest expense, net, in the Company's condensed consolidated statement of operations for the three months ended March 31, 2021. The Company is required to make quarterly principal payments on the 2020 Term Loan aggregating approximately $20 million per year in the first three years and $30 million in the fourth year, with the final payment approximating $300 million due on the maturity date.

The Third Amendment increased the Borrower's ability to incur new incremental revolving commitments or term loans. Such indebtedness can be incurred up to an aggregate dollar limit equal to 100% of the Company's Consolidated Adjusted EBITDA (as defined in the 2020 Credit Facility) as of the most recently ended fiscal quarter for which financial statements have been delivered to the Lenders, plus additional amounts, so long as the Borrower's Consolidated Net Leverage Ratio (as defined in the Credit Agreement) does not exceed 2.75:1.00, increased from 2.25:1.00 under the First Amendment. The Third Amendment also increased the amount of Unrestricted Cash (as defined in the 2020 Credit Facility) used in calculating the Borrower's Consolidated Net Leverage Ratio from $10.0 million to $25.0 million.

At March 31, 2021, the Company had an outstanding 2020 Term Loan balance of $390.6 million at an average interest rate of 3.40% and $6.4 million of letters of credit outstanding with an interest rate of 2.50%.

The Company was in compliance with all covenants of the 2020 Credit Facility at both March 31, 2021 and December 31, 2020.

Short-Term Loan

From time to time, the Company enters into uncommitted and unsecured short-term loans to finance exports in China. The Company did not have any such short-term loans outstanding at March 31, 2021 and December 31, 2020.

Letters of Credit and Performance and Bid Bonds

The Company uses letters of credit, performance and bid bonds in the course of its business. At March 31, 2021, the Company had bank guarantees, performance and bid bonds under various uncommitted facilities (collectively, the "Guarantees") aggregating $26.9 million and $6.4 million of letters of credit under the 2020 Credit Facility (the "Letters of Credit"). At December 31, 2020, the Company had Guarantees aggregating $27.0 million and $5.6 million of Letters of Credit. At both March 31, 2021 and December 31, 2020, the Company had cash collateral of $2.7 million supporting the Guarantees, which are included in Restricted cash in the condensed consolidated balance sheets.


(11) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company is exposed to financial market risk related to foreign currency fluctuations and changes in interest rates. These exposures are actively monitored by management. To manage the volatility related to the exposure to changes in interest rates, the Company has entered into a derivative financial instrument. Management's objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in interest rates. Ribbon's policies and practices are to use derivative financial instruments only to the extent necessary to manage exposures. Ribbon does not hold or issue derivative financial instruments for trading or speculative purposes.

The Company records derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a

hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a specific risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge, or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

Cash Flow Hedge of Interest Rate Risk

The 2020 Term Loan Facility had outstanding balances of $390.6 million and $393.1 million at March 31, 2021 and December 31, 2020, respectively. The 2020 Revolving Credit Facility was undrawn at both March 31, 2021 and December 31, 2020. Borrowings under the 2020 Credit Facility have variable interest rates based on LIBOR (see Note 10). As a result of exposure to interest rate movements, during March 2020, the Company entered into an interest rate swap arrangement, which effectively converted its $400 million term loan with its variable interest rate based upon one-month LIBOR to an aggregate fixed rate of 0.904%, plus a leverage-based margin as defined in the 2020 Credit Facility. The notional amount of this swap at March 31, 2021 was $400 million, and the swap matures on March 3, 2025, the same date the 2020 Credit Facility matures.

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company is using an interest rate swap as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of designated derivatives that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) in the condensed consolidated balance sheet and is subsequently reclassified into earnings in the period that the hedged forecasted transactions affect earnings. During the three months ended March 31, 2021 and 2020, such a derivative was used to hedge the variable cash flows associated with the outstanding borrowings under the 2020 Credit Facility and the Company has accounted for this derivative as an effective hedge. Any ineffective portion of the change in the fair value of the derivative would be recognized directly in earnings.

Amounts reported in accumulated other comprehensive income (loss) related to the Company's derivative are reclassified to interest expense as interest is accrued on the Company’s variable-rate debt. Based upon projected forward rates, the Company estimates as of March 31, 2021 that $3.1 million may be reclassified as an increase to interest expense over the next twelve months.

The impact of the Company’s derivative financial instrument on its condensed consolidated statement of comprehensive income (loss) for the three months ended March 31, 2021 and 2020 was as follows (in thousands):

(12) REVENUE RECOGNITION

The Company derives revenue from two primary sources: products and services. Product revenue includes the Company's hardware and software that function together to deliver the products' essential functionality. Software and hardware are also sold on a standalone basis. Services include customer support (software updates, upgrades and technical support), consulting, design services, installation services and training. Generally, contracts with customers contain multiple performance obligations, consisting of products and services. For these contracts, the Company accounts for individual performance obligations separately if they are considered distinct.

When an arrangement contains more than one performance obligation, the Company will allocate the transaction price to each performance obligation on a relative standalone selling price basis. The Company utilizes the observable price of goods and services when they are sold separately to similar customers in order to estimate standalone selling price.

The Company's software licenses typically provide a perpetual right to use the Company's software. The Company also sells term-based software licenses that expire and Software-as-a-Service ("SaaS")-based software which are referred to as subscription arrangements. The Company does not customize its software nor are installation services required, as the customer has a right to utilize internal resources or a third-party service company. The software and hardware are delivered before related services are provided and are functional without professional services or customer support. The Company has concluded that its software licenses are functional intellectual property that are distinct, as the user can benefit from the software on its own. Product revenue is typically recognized upon transfer of control or when the software is made available for download, as this is the point the user of the software can direct the use of, and obtain substantially all of the remaining benefits from, the functional intellectual property. The Company begins to recognize software revenue related to the renewal of subscription software licenses at the start of the subscription period.

The Company offers warranties on its products. Certain of the Company's warranties are considered to be assurance-type in nature, ensuring the product is functioning as intended. Assurance-type warranties do not represent separate performance obligations. The Company also sells separately-priced maintenance service contracts which qualify as service-type warranties and represent separate performance obligations. The Company does not allow and has no history of accepting product returns.

Services revenue includes revenue from customer support and other professional services. Customer support includes software updates on a when-and-if-available basis, telephone support, integrated web-based support and bug fixes or patches. The Company sells its customer support contracts at a percentage of list or net product price. Customer support revenue is recognized ratably over the term of the customer support agreement, which is typically one year.

The Company's professional services include consulting, technical support, resident engineer services, design services and installation services. Because control transfers over time, revenue is recognized based on progress toward completion of the performance obligation. The method to measure progress toward completion requires judgment and is based on the nature of the products or services to be provided. The Company generally uses the input method to measure progress for its contracts because it believes such method best depicts the transfer of assets to the customer, which occurs as the Company incurs costs for the contracts. However, in some instances, the Company uses the output method because it best depicts the transfer of asset to the customer. Under the cost-to-cost measure of progress, the progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. When the measure of progress is based upon expended labor, progress toward completion is measured as the ratio of labor time expended to date versus the total
25


RIBBON COMMUNICATIONS INC.
Notes to Condensed Consolidated Financial Statements (Continued)
(unaudited)
estimated labor time required to complete the performance obligation. Revenue is recorded proportionally as costs are incurred or as labor is expended. Costs to fulfill these obligations include internal labor as well as subcontractor costs.

Customer training includes courses offered by the Company. The related revenue is typically recognized as the training services are performed.

The Company's typical performance obligations include the following:
Performance ObligationWhen Performance Obligation is Typically SatisfiedWhen Payment is Typically Due
Software and Product Revenue
Software licenses (perpetual or term)Upon transfer of control; typically, when made available for download (point in time)Generally, within 30 days of invoicing except for term licenses, which may be paid for over time
Software licenses (subscription)Upon activation of hosted site (over time)Generally, within 30 days of invoicing
HardwareWhen control of the hardware passes to the customer; typically, upon delivery (point in time)Generally, within 30 days of invoicing
Software upgradesUpon transfer of control; typically, when made available for download (point in time)Generally, within 30 days of invoicing
Customer Support Revenue
Customer supportRatably over the course of the support contract (over time)Generally, within 30 days of invoicing
Professional Services
Other professional services (excluding training services)As work is performed (over time)Generally, within 30 days of invoicing (upon completion of services)
TrainingWhen the class is taught (point in time)Generally, within 30 days of services being performed

Significant Judgments

The Company's contracts with customers often include promises to transfer multiple products and services to the customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment.

Judgment is required to determine the standalone selling price ("SSP") for each distinct performance obligation. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customers and circumstances. In these instances, the Company may use information such as the size of the customer and geographic region in determining the SSP.

Deferred Revenue

Deferred revenue is a contract liability representing amounts collected from or invoiced to customers in excess of revenue recognized. This results primarily from the billing of annual customer support agreements where the revenue is recognized over the term of the agreement. The value of deferred revenue will increase or decrease based on the timing of recognition of revenue.

Revenue Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable; unbilled receivables, which are contract assets; and customer advances and deposits, which are contract liabilities, in the Company's condensed consolidated balance sheets. Amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Completion of services and billing may occur subsequent to revenue recognition, resulting in contract assets. The Company may receive advances or deposits from its customers before revenue is recognized, resulting in contract liabilities that are classified as deferred revenue. These assets and liabilities are reported in the Company's condensed consolidated balance sheets on a contract-by-contract basis as of the end of each reporting period. Changes in the contract asset and liability balances during the three months ended March 31, 2021 were not materially impacted by any factors other than billing and revenue recognition. Nearly all of the Company's deferred revenue balance is related to services revenue, primarily customer support contracts. Unbilled receivables stem primarily from engagements where services have been performed; however, billing cannot occur until services are completed.

In some arrangements, the Company allows customers to pay for term-based software licenses and products over the term of the software license. The Company also sells SaaS-based software under subscription arrangements, with payment terms over the term of the SaaS agreement. Amounts recognized as revenue in excess of amounts billed are recorded as unbilled receivables. Unbilled receivables that are anticipated to be invoiced in the next twelve months are included in Accounts receivable on the Company's condensed consolidated balance sheets. The changes in the Company's accounts receivable, unbilled receivables and deferred revenue balances for the three months ended March 31, 2021 were as follows (in thousands):
Accounts receivableUnbilled accounts receivableDeferred revenue (current)Deferred revenue (long-term)

Balance at March 31, 2021$151,612 57,551 $102,103 $23,054 


The Company recognized approximately $42 million of revenue in the months ended March 31, 2021 that was recorded as deferred revenue at December 31, 2020 and approximately $41 million of revenue in the three months ended March 31, 2020 that was recorded as deferred revenue at December 31, 2019. Of the Company's deferred revenue reported as long-term in its condensed consolidated balance sheet at March 31, 2021, the Company expects that approximately $11 million will be

recognized as revenue in 2022, approximately $8 million will be recognized as revenue in 2023 and approximately $4 million will be recognized as revenue in 2024 and beyond.

All freight-related customer invoicing is recorded as revenue, while the shipping and handling costs that occur after control of the promised goods or services transfer to the customer are reported as fulfillment costs, a component of Cost of revenue - product in the Company's condensed consolidated statements of operations.

Deferred Commissions Cost

Sales commissions earned by the Company's employees are considered incremental and recoverable costs of obtaining a contract with a customer. Expense related to commission payments has been deferred on our condensed consolidated balance sheet and is being amortized over the expected life of the customer contract, which averages five years. The current and long-term portions of deferred commission expense are included as components of Other current assets and Other assets, respectively. At both March 31, 2021 and December 31, 2020, the Company had $4.1 million of deferred sales commissions capitalized.


(13) OPERATING SEGMENT INFORMATION

The Company has two reportable segments, which are intended to align with the manner in which the business is managed: Cloud and Edge, and IP Optical Networks.

The Cloud and Edge segment provides secure and reliable software and hardware products, solutions and services for enabling Voice over Internet Protocol ("VoIP") communications, Voice over Long-Term Evolution ("VoLTE") and Voice Over 5G ("VoNR") communications and Unified Communications and Collaboration ("UC&C") within service provider and enterprise networks and from the cloud. The Cloud and Edge products are increasingly software-centric and cloud-native for deployment on private, public or hybrid cloud infrastructures, in data centers, on enterprise premises and within service provider networks. Ribbon's Cloud and Edge product portfolio consists of our Session Border Controller ("SBC") products and our Network Transformation ("NTR") products.

The Company has not provided segment asset information as such information is not provided to the CODM and accordingly, asset information is not used in assessing segment performance. Please see Note 6 for information regarding the allocation of goodwill between segments. Segment revenue and expenses included in the tables below represent direct revenue and expenses attributable to each segment for revenue, adjusted gross profit, and the research and development expense component of adjusted EBITDA. The Company's sales, marketing, and general and administrative functions support both segments and accordingly, these costs are allocated to both segments.

The CODM utilizes revenue, adjusted gross profit and adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) to measure and assess each segment's performance. The Company calculates adjusted EBITDA by excluding from income (loss) from operations: depreciation; amortization of acquired intangible assets; stock-based compensation; certain litigation costs; acquisition-, disposal- and integration-related expense; and restructuring and related expense. These adjusted measures may also exclude other items in future periods that the Company believes are not part of the Company's core business. Adjusted gross profit and adjusted EBITDA are not financial measures determined in accordance with U.S. GAAP and may not be comparable to similarly titled measures used by other companies and should not be considered a substitute for income (loss)

(15) COMMON STOCK REPURCHASES

In the second quarter of 2019, the Company's Board of Directors (the "Board") approved a stock repurchase program (the "Repurchase Program") pursuant to which the Company could repurchase up to $75 million of its common stock prior to April 18, 2021. The Company did not repurchase any common stock during the three months ended March 31, 2021 or 2020. At both March 31, 2020 and December 31, 2020, the Company had $70.5 million remaining under the Repurchase Program for future repurchases. The Repurchase Program expired on April 18, 2021.


(16) STOCK-BASED COMPENSATION PLANS

2019 Stock Incentive Plan

The Company's Amended and Restated 2019 Incentive Award Plan (the "2019 Plan") provides for the award of options to purchase the Company's common stock ("stock options"), stock appreciation rights ("SARs"), restricted stock awards ("RSAs"), performance-based stock awards ("PSAs"), restricted stock units ("RSUs"), performance-based stock units ("PSUs") and other stock- or cash-based awards. Awards can be granted under the 2019 Plan to the Company's employees, officers and non-employee directors, as well as consultants and advisors of the Company and its subsidiaries.

2007 Plan

The Company's 2007 Plan provided for the award of stock options, SARs, RSAs, PSAs, RSUs, PSUs and other stock-based awards to employees, officers, non-employee directors, consultants and advisors of the Company and its subsidiaries. On and following June 5, 2019, with the exception of shares underlying awards outstanding as of that date, no additional shares may be granted under the 2007 Plan.

Assumed Stock Plans

In connection with the acquisition of Edgewater Networks, Inc. in August 2018, the Company assumed Edgewater's Amended and Restated 2002 Stock Option Plan (the "Edgewater Plan") to the extent of the shares underlying the options outstanding under the Edgewater Plan as of the Edgewater Acquisition Date (the "Edgewater Options"). The Edgewater Options were converted to Ribbon stock options (the "Ribbon Replacement Options") which are vesting under the same
31

schedules as the respective Edgewater Options.

In connection with the Company's acquisitions of Performance Technologies Inc. ("PT") in 2014, and Network Equipment Technologies, Inc. ("NET") in 2012, the Company assumed their stock plans (collectively, the "Assumed Plans"). Any outstanding awards under the Assumed Plans that in the future expire, terminate, are cancelled or surrendered, or are repurchased by the Company will be returned to the 2019 Plan. Accordingly, no additional shares may be granted under the Assumed Plans.

Executive Equity Arrangements

Inducement Awards

In connection with his appointment as President and Chief Executive Office of Ribbon, and as an inducement for Bruce McClelland's ("Mr. McClelland") commencement of employment, the Company awarded Mr. McClelland sign-on equity grants, comprised of 462,963 RSUs and a PSU grant with both market and service conditions (the "Inducement PSUs") on March 16, 2020. The RSUs vested and were released to Mr. McClelland on March 16, 2021. Subject to Mr. McClelland's continued employment, the Inducement PSUs are eligible to vest and be settled in up to 4,750,000 shares of Ribbon common stock upon the achievement of specified share price thresholds on or prior to September 1, 2024. The first share price threshold for Mr. McClelland’s Inducement PSUs was achieved on February 26, 2021, and accordingly 1,333,333 shares were released to him. These releases are included in the applicable tables below.

Performance-Based Stock Grants

In addition to granting RSUs to its executives and certain of its employees, the Company also grants PSUs to certain of its executives, including the Inducement PSUs granted to Mr. McClelland as described above.

In 2021, 2020 and 2019, the Company granted certain of its executives (the "2021 PSUs", "2020 PSUs" and "2019 PSUs", respectively), of which 60% of each executive's PSU grant had both performance and service conditions (the "Performance PSUs") and 40% had both market and service conditions (the "Market PSUs").

Each executive's Performance PSU grant is comprised of three consecutive fiscal year performance periods beginning in the year of grant (each, a "Fiscal Year Performance Period"), with one-third of the Performance PSUs attributable to each Fiscal Year Performance Period. The number of shares that will be vest for each Fiscal Year Performance Period, if any, will be based on the achievement of certain metrics related to the Company's financial performance for the applicable year on a standalone basis (each, a "Fiscal Year Performance Condition"). The Company's achievement of the goals for each Fiscal Year Performance Condition (and the number of shares of Company common stock to vest as a result thereof) are being measured on a linear sliding scale in relation to specific threshold, target and stretch performance conditions, with any shares earned vesting in the first quarter of the fiscal year following the third Performance Period of the grant, pending each executive's continued employment with the Company through that date. The number of shares of common stock underlying the Performance PSUs that can be earned will in no event exceed 200% of the Performance PSUs. Shares subject to the Performance PSUs that fail to be earned will be forfeited.

The Market PSUs have one three-year performance period, beginning January 1 in the year of grant and ending on December 31, three years thereafter (the "Market Performance Period"). The number of shares subject to the Market PSUs that will vest, if any, will be dependent upon the Company's total shareholder return ("TSR") compared with the TSR of the companies included in a custom index for the applicable Market Performance Period, measured by the Compensation Committee after the Market Performance Period ends, with any shares earned vesting in the first quarter of the fiscal year following the respective Market Performance Period, pending each executive's continued employment with the Company through that date. The number of shares of common stock underlying the Market PSUs that can be earned will in no event exceed 200% of the Market PSUs. Shares subject to the Market PSUs that fail to be earned will be forfeited.

In addition, in connection with his appointment as Executive Vice President and General Manager, Packet Optical Networking, the Company granted Sam Bucci 133,333 PSUs (the "Bucci Stock Price PSUs") with both market and service conditions. Subject to Mr. Bucci's continued employment, the Bucci Stock Price PSUs were eligible to vest and be settled in

shares of Ribbon's common stock upon the achievement of a specific share price threshold on or prior to January 31, 2022. The share price threshold for Mr. Bucci’s Stock Price PSUs was achieved on February 12, 2021, and the shares were released to him. This release is included in the applicable table below.

Accounting for Performance PSUs. Once the grant date criteria have been met for a Fiscal Year Performance Period, the Company records stock-based compensation expense for the respective underlying Performance PSUs based on its assessment of the probability that each performance condition will be achieved and the level, if any, of such achievement. The Compensation Committee determines the number of shares earned, if any, after the Company's financial results for each Fiscal Year Performance Period are finalized. Upon the determination by the Compensation Committee of the number of shares that will be received upon vesting of the Performance PSUs, such number of shares becomes fixed and the unamortized expense is recorded through the remainder of the service period, generally three years from the date of grant, at which time the total Performance PSUs earned, if any, will vest, pending each executive's continued employment with the Company through that date.

Accounting for Market PSUs. PSUs that include a market condition require the use of a Monte Carlo simulation approach to model future stock price movements based upon the risk-free rate of return, the date of return, the volatility of each entity and the pair-wise covariance between each entity. These results are then used to calculate the grant date fair values of the respective PSUs. The Company is required to record expense for the PSUs with market conditions through their respective final vesting dates, regardless of the number of shares that are ultimately earned.

At March 31, 2021, the calculation of the grant date fair value of the Market PSUs granted on March 15, 2021 had not been completed. The Company used a grant date fair value of $8.65, the closing stock price on the date of grant, to calculate expense attributable to the three months ended March 31, 2021 for these Market PSUs. The Company expects to complete the Monte Carlo valuation of these Market PSUs and will record a cumulative adjustment to expense to account for the change in grant date fair value, if any, in the second quarter of 2021. The Company does not expect any such adjustment to have a material impact on its consolidated financial statements.

Employee Bonus Program

Effective in 2021, the Company added an equity component to its cash bonus program for eligible employees, under which RSUs with a grant date fair value equal to 50% of each employee's target cash bonus were granted to each such employee (the "Bonus RSUs"). Correspondingly, cash target bonuses for eligible employees were reduced by 50%. The Company implemented this program to expand the opportunities for stock ownership more broadly throughout the Company. The Bonus RSU grants are included in the applicable table below.

At March 31, 2021, there was $36.4 million, net of expected forfeitures, of unrecognized stock-based compensation expense related to unvested stock options, stock awards and stock units. This expense is expected to be recognized over a weighted average period of approximately two years.


(17) LEASES

The Company has operating and finance leases for corporate offices, research and development facilities, and certain equipment. Operating leases are reported separately in the Company's condensed consolidated balance sheets. Assets acquired under finance leases are included in Property and equipment, net, in the condensed consolidated balance sheets.

The Company determines if an arrangement is a lease at inception. A contract is determined to contain a lease component if the arrangement provides the Company with a right to control the use of an identified asset. Lease agreements may include lease and non-lease components. In such instances for all classes of underlying assets, the Company does not separate lease and non-lease components but rather, accounts for the entire arrangement under leasing guidance. Leases with an initial term of 12 months or less are not recorded on the balance sheet and lease expense for these leases is recognized on a straight-line basis over the lease term.

Right-of-use assets and lease liabilities are initially measured based on the present value of the future minimum fixed lease payments (i.e., fixed payments in the lease contract) over the lease term at the commencement date. As the Company's existing leases do not have a readily determinable implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of future minimum fixed lease payments. The Company calculates its incremental borrowing rate to reflect the interest rate that it would have to pay to borrow on a collateralized basis an amount equal to the lease payments in a similar economic environment over a similar term and considers its historical borrowing activities and market data from entities with comparable credit ratings in this determination. The measurement of the right-of-use asset also includes any lease payments made prior to the commencement date (excluding any lease incentives) and initial direct costs incurred. The Company assessed its right-of-use assets for impairment as of March 31, 2021 and December 31, 2020 and determined no impairment has occurred.

Lease terms may include options to extend or terminate the lease and the Company incorporates such options in the lease term when it has the unilateral right to make such an election and it is reasonably certain that the Company will exercise that option. In making this determination, the Company considers its prior renewal and termination history and planned usage of the assets under lease, incorporating expected market conditions.

For operating leases, lease expense for minimum fixed lease payments is recognized on a straight-line basis over the lease term. The expense for finance leases includes both interest and amortization expense components, with the interest component calculated based on the effective interest method and the amortization component calculated based on straight-line amortization of the right-of-use asset over the lease term. Lease contracts may contain variable lease costs, such as common area maintenance, utilities and tax reimbursements that vary over the term of the contract. Variable lease costs are not included in minimum fixed lease payments and as a result, are excluded from the measurement of the right-of-use assets and lease

liabilities. The Company expenses all variable lease costs as incurred.

In connection with the 2019 Restructuring Initiative, certain lease assets related to facilities are being partially or fully vacated as the Company consolidates its facilities. The Company has no plans to enter into sublease agreements for certain facilities. The Company ceased use of these facilities in the first quarter of 2021, the first and fourth quarters of 2020 and the third quarter of 2019. Accordingly, the Company accelerated the amortization of the associated lease assets through the planned cease-use date of each facility, resulting in additional amortization expense of $3.4 million and $0.1 million in the three months ended March 31, 2021 and 2020, respectively. The Company also recorded expense of $1.4 million in the aggregate in the three months ended March 31, 2021 for all estimated future variable lease costs related to these facilities. The Company recorded nominal expense for all estimated future variable lease costs in the three months ended March 31, 2020.

All accelerated amortization and accrual of future variable costs were recorded as Restructuring and related expense in the Company's condensed consolidated statements of operations. At March 31, 2021 and December 31, 2020, the Company had accruals of $2.1 million and $0.8 million, respectively, for all future anticipated variable lease costs related to these facilities. The Company may incur additional future expense if it is unable to sublease other locations included in the Facilities Initiative.

The Company leases its corporate offices and other facilities under operating leases, which expire at various times through 2032. In December 2020, the Company began relocating from its former leased Plano, Texas facility to its recently completed leased facility, also located in Plano, Texas, which became the Company's corporate headquarters. The Company's relocation to the new corporate headquarters was completed in the first quarter of 2021.

(18) INCOME TAXES

The Company's income tax provisions for the three months ended March 31, 2021 and 2020 reflect the Company's estimates of the effective rates expected to be applicable for the respective full years, adjusted for any discrete events, which are recorded in the period that they occur. These estimates are reevaluated each quarter based on the Company's estimated tax expense for the full year. The estimated effective tax rate includes the impact of valuation allowances in various jurisdictions.



(19) COMMITMENTS AND CONTINGENCIES

Liabilities for Royalty Payments to the IIA. Prior to the ECI Acquisition, ECI had received research and development grants from the Office of the Innovation Authority of the Israeli Ministry of Economics (the "IIA"). The Company assumed ECI's contract with the IIA, which requires the Company to pay royalties to the IIA on proceeds from the sale of products which the Israeli government has supported by way of research and development grants. The royalties for grants prior to 2017 were calculated at the rates of 1.3% to 5.0% of the aggregated proceeds from the sale of such products developed at certain of the Company's R&D centers, up to an amount not exceeding 100% of such grants plus interest at LIBOR. Effective for grants approved in 2017 and subsequently, interest was calculated at the higher of LIBOR plus 1.5% to 2.75%. At March 31, 2021, the Company's maximum possible future royalties commitment, including $5.2 million of unpaid royalties accrued, was $42.0 million, including interest of $2.0 million, based on estimates of future product sales, grants received from the IIA not yet repaid, and management's estimation of products still to be sold.

Research and Development Grants. The Company records grants received from the IIA as a reduction to research and development expense. Royalties payable to the IIA are recognized pursuant to sales of related products and are classified as Cost of revenue.

Litigation. On November 8, 2018, Ron Miller, a purported stockholder of the Company, filed a Class Action Complaint (the "Miller Complaint") in the United States District Court for the District of Massachusetts (the "Massachusetts District Court") against the Company and three of its former officers (collectively, the "Defendants"), claiming to represent a class of purchasers of Sonus common stock during the period from January 8, 2015 through March 24, 2015 and alleging violations of the federal securities laws. Similar to a previous complaint entitled Sousa et al. vs. Sonus Networks, Inc. et al., which was dismissed with prejudice by an order dated June 6, 2017, the Miller Complaint claims that the Defendants made misleading forward-looking statements concerning Sonus' expected fiscal first quarter of 2015 financial performance, which statements were also the subject of an August 7, 2018 Securities and Exchange Commission Cease and Desist Order, whose findings the Company neither admitted nor denied. The Miller plaintiffs are seeking monetary damages.

After the Miller Complaint was filed, several parties filed and briefed motions seeking to be selected by the Massachusetts District Court to serve as a Lead Plaintiff in the action. On June 21, 2019, the Massachusetts District Court appointed a group as Lead Plaintiffs and the Lead Plaintiffs filed an amended complaint on July 19, 2019. On August 30, 2019, the Defendants

filed a motion to dismiss the Miller Complaint and, on October 4, 2019, the Lead Plaintiffs filed an opposition to the motion to dismiss. There was an oral argument on the motion to dismiss on February 12, 2020.

In addition, the Company is often a party to disputes and legal proceedings that it considers routine and incidental to its business. Management does not expect the results of any of these actions to have a material effect on the Company's business or condensed consolidated financial statements.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations


The following discussion of the financial condition and results of operations of Ribbon Communications Inc. should be read in conjunction with the condensed consolidated financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q and the audited financial statements and notes thereto and Management's Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the U.S. Securities and Exchange Commission on February 26, 2021.

Overview

We are a leading global provider of communications technology to service providers and enterprises. We provide a broad range of software and high-performance hardware products, solutions and services that enable the secure delivery of data and voice communications for residential consumers and for small, medium and large enterprises and industry verticals such as finance, education, government, utilities and transportation. Our mission is to create a recognized global technology leader providing increasingly cloud-centric solutions that enable the secure exchange of information, with unparalleled scale, performance and elasticity. Headquartered in Plano, Texas, we have a global presence with research and development and/or sales and support locations in over thirty-five countries around the world.

Impact of COVID-19 on Our Business

In 2020, a novel strain of the coronavirus (COVID-19) was declared by the World Health Organization to be a global pandemic. The COVID-19 pandemic has had a negative effect on the global economy, disrupting the various manufacturing, commodity and financial markets and increasing volatility, and has impeded global supply chains, including that of our IP Optical Networks operating segment. Continued dampened global economic conditions as a result of the COVID-19 pandemic, especially in areas where a vaccine rollout is slower, such as India, may cause our customers to restrict spending or delay purchases for an indeterminate period of time and consequently cause our revenues to decline. In addition, our ability to deliver our solutions as agreed upon with our customers depends on the ability of our global contract manufacturers, vendors, licensors and other business partners to deliver products or perform services we have procured from them. While, to date, we have not experienced material issues, if the ongoing COVID-19 pandemic impairs the ability of our business partners to support us on a timely basis, or negatively impacts the demand for our customers' other products and services, our ability to perform our customer contracts as well as the demand for our solutions may suffer. In addition, disruptions from the COVID-19 pandemic could include, and with respect to our IP Optical Networks operating segment have included, disruption of logistics necessary to import, export and deliver our solutions. The COVID-19 pandemic continues to limit in some locations the ability of our employees to perform their work due to illness caused by the pandemic or local, state or federal orders requiring employees to remain at home. The degree to which the COVID-19 pandemic ultimately impacts our business, financial position and results of operations will depend on future developments beyond our control, including the effectiveness and timing of any vaccines, the frequency and duration of future waves of infection, the effectiveness and timing of any vaccines, the extent of actions to contain or treat the virus, how quickly and to what extent normal economic and operating conditions can resume, and the severity and duration of the global economic downturn that results from the pandemic.

As a response to the ongoing COVID-19 pandemic, we have continued to implement plans to manage our costs. As part of that plan, we implemented a temporary wage reduction of 10% to 50% applicable to the base salary of most of our employees, which salary reduction ended in 2020. We have eliminated all travel except where necessary to meet customer or regulatory needs and acted to limit discretionary spending. To the extent the business disruption continues for an extended period, additional cost management actions will be considered. Any future asset impairment charges, increases in the allowance for doubtful accounts or restructuring charges could be more likely and will be dependent on the severity and duration of this crisis.

Reclassification of Amortization of Acquired Intangible Assets

In 2020, we reclassified amounts recorded for amortization of acquired intangible assets in prior presentations from Cost of revenue - product and Sales and marketing to a separate line included in operating expenses in our consolidated statements of operations. Our Management believes this presentation enhances the comparability of our financial statements to industry peers. These reclassifications did not impact our operating income (loss), net income (loss) or earnings (loss) per share for any historical periods. These reclassifications also did not impact our consolidated balance sheets or consolidated statements of cash flows.

This reclassification resulted in reductions to Cost of revenue - product and Sales and marketing of $8.9 million and $5.4 million, respectively, reclassified to Amortization of acquired intangible assets for the three months ended March 31, 2020.
40


The reduction in the three months ended March 31, 2020 to Cost of revenue - product increased our product gross profit as a percentage of product revenue ("product gross margin") and our total gross profit as a percentage of revenue ("total gross margin) by approximately 12 percentage points and 6 percentage points, respectively.

Acquisition of ECI Telecom Group Ltd.

On March 3, 2020 (the "ECI Acquisition Date"), we completed the acquisition of ECI in accordance with the terms of the Agreement and Plan of Merger, dated as of November 14, 2019, by and among Ribbon, an indirect wholly-owned subsidiary of Ribbon ("Merger Sub"), Ribbon Communications Israel Ltd., ECI, and ECI Holding (Hungary) kft, pursuant to which Merger Sub merged with and into ECI, with ECI surviving such merger as a wholly-owned subsidiary of Ribbon (the "ECI Acquisition"). Prior to the ECI Acquisition Date, ECI was a privately-held global provider of end-to-end packet-optical transport and software-defined networking ("SDN") and network function virtualization ("NFV") solutions for service providers, enterprises and data center operators. Ribbon believes the ECI Acquisition positions the Company for growth and enhances its competitive strengths by expanding its product portfolio beyond solutions primarily supporting voice applications to include data applications and optical networking.

As consideration for the ECI Acquisition, we issued the ECI shareholders and certain others 32.5 million shares of Ribbon common stock with a fair value of $108.6 million (the "Stock Consideration") and paid $322.5 million of cash, comprised of $183.3 million to repay ECI's outstanding debt, including both principal and interest, and $139.2 million paid to ECI's selling shareholders (the "Cash Consideration"). In addition, ECI shareholders received $33.4 million from the sale of certain of ECI's real estate assets. Cash Consideration was financed through cash on hand and committed debt financing consisting of a new $400 million term loan facility and new $100 million revolving credit facility, which was undrawn at the ECI Acquisition Date. The ECI Acquisition has been accounted for as a business combination and the financial results of ECI have been included in our consolidated financial statements for the periods subsequent to the ECI Acquisition Date.

Sale of Kandy Communications Business

On December 1, 2020 (the "Kandy Sale Date"), we completed the sale of our Kandy Communications Business to American Virtual Cloud Technologies, Inc. ("AVCT"). AVCT purchased the assets and assumed certain liabilities associated with the Kandy Communications Business, as well as all of the outstanding interests in Kandy Communications LLC, a subsidiary of the Company (the "Kandy Sale"). The assets acquired and liabilities assumed by AVCT in connection with the Kandy Sale were primarily comprised of accounts receivable, property and equipment, trade accounts payable and employee-related accruals.

As sale consideration, AVCT paid us $45.0 million, subject to certain adjustments, in the form of units of AVCT's securities (the "AVCT Units"), with each AVCT Unit consisting of: $1,000 in principal amount of AVCT’s Series A-1 convertible debentures (the “Debentures”); and (ii) one warrant to purchase 100 shares of AVCT common stock, $0.0001 par value (the “Warrants”), as consideration for the Kandy Sale. We received 43,778 AVCT Units as sale consideration on the Kandy Sale Date.

The Debentures bear interest at a rate of 10% per annum, which will be added to the principal amount of the Debentures, except upon maturity, in which case accrued and unpaid interest is payable in cash. The entire principal of each Debenture, together with accrued and unpaid interest thereon, is due and payable on the earlier of the May 1, 2023 maturity date or the occurrence of a Change in Control as defined in the definitive purchase agreement, as amended (the "Amended Kandy Agreement"). Each Debenture is convertible, in whole or in part, at any time at our option into that number of shares of AVCT common stock, calculated by dividing the principal amount being converted, together with all accrued and unpaid interest thereon, by the applicable conversion price, initially $3.45. The Debentures are subject to mandatory redemption if the AVCT stock price is at or above $6.00 per share for 40 trading days in any 60 consecutive trading day period, subject to the satisfaction of certain other conditions. The conversion price is subject to customary adjustments including, but not limited to, stock dividends, stock splits and reclassifications. At the Company's option, up to $5.0 million of the Debentures may be redeemed by AVCT at par in the event AVCT raises at least $50.0 million in its offering of AVCT Units. As of February 19, 2021, the stock price had traded above $6.00 for 40 days within a 60 consecutive trading day period, and accordingly, the Debentures will be converted to shares of AVCT common stock upon the completion of customary regulatory filings by AVCT.

The Warrants are independent of the Debentures and entitle us to purchase 4,377,800 shares of AVCT common stock at an exercise price of $0.01 per share. The Warrants expire on December 1, 2025, and were immediately exercisable on the Kandy Sale Date.

41


We had not redeemed any of the Debentures or exercised any of the Warrants as of March 31, 2021. We are also subject to a lock-up provision which limits our ability to sell any shares of AVCT common stock underlying the Debentures and the Warrants prior to June 1, 2021, except in certain transactions.

We determined that the AVCT Units had a fair value of $84.9 million at the Kandy Sale Date, comprised of the Debentures with a fair value of $66.3 million and the Warrants with a fair value of $18.6 million. The value of the net assets sold to AVCT totaled $1.3 million, resulting in a gain on the sale of $83.6 million.

We are calculating the fair value of the Debentures and Warrants at each quarter-end and recording any adjustments to the fair values in Other expense, net. At March 31, 2021 and December 31, 2020, the aggregate fair value of the Debentures and Warrants was $92.7 million and $115.2 million, respectively. We recorded the loss of $23.9 million arising from the decrease in the fair value of the Debentures and Warrants from March 31, 2021 to March 31, 2021 in Other expense, net, in our condensed consolidated statement of operations for the three months ended March 31, 2021. The loss was partially offset by $1.5 million of interest which was added to the principal of the Debentures. The interest is included in Interest (expense) income, net, in the consolidated statement of operations for the three months ended March 31, 2021. The fair values of the Debentures and Warrants are reported as Investments in our condensed consolidated balance sheets at March 31, 2021 and December 31, 2020.

Operating Segments

Effective in the fourth quarter of 2020 and in connection with the ECI Acquisition, our CODM began to assess our performance based on the performance of two separate organizations within Ribbon: the Cloud and Edge operating segment ("Cloud and Edge") and the IP Optical Networks operating segment ("IP Optical Networks"). Amounts attributable to IP Optical Networks in the three months ended March 31, 2020 are for the period subsequent to the ECI Acquisition Date. For additional details regarding our operating segments, see Note 13 - Operating Segment Information to our condensed consolidated financial statements.

Financial Overview

Financial Results

We reported losses from operations of $12.6 million and $28.7 million for the three months ended March 31, 2021 and 2020, respectively.

Our revenue was $192.8 million in the three months ended March 31, 2021, comprised of $125.4 million attributable to our Cloud and Edge segment and $67.4 million attributable to our IP Optical Networks segment. Our revenue was $158.0 million in the three months ended March 31, 2020, comprised of $128.0 million attributable to our Cloud and Edge segment and $30.0 million attributable to our IP Optical Networks segment.

Our gross profit was $110.5 million in the three months ended March 31, 2021, comprised of $84.1 million attributable to our Cloud and Edge segment and $26.4 million attributable to our IP Optical Networks segment. Our gross profit in the three months ended March 31, 2020 was $90.5 million, comprised of $78.8 million attributable to our Cloud and Edge segment and $11.7 million attributable to our IP Optical Networks segment. Our gross profit as a percentage of revenue ("total gross margin") in both three-month periods ended March 31, 2021 and 2020 was 57.3% . Our gross margin attributable to our Cloud and Edge segment in the three months ended March 31, 2021 and 2020 was 67.1% and 61.5%, respectively, and attributable to our IP Optical Networks segment was 39.2% in both the three months ended March 31, 2021 and 2020.

Our operating expenses were $123.2 million and $119.3 million in the three months ended March 31, 2021 and 2020, respectively. Operating expenses for the three months ended March 31, 2021 included $1.2 million of acquisition- and integration-related expense and $6.0 million of restructuring and related expense. Operating expenses for the three months ended March 31, 2020 included $12.4 million of acquisition-, disposal- and integration-related expense and $2.1 million of restructuring and related expense.

We recorded stock-based compensation expense of $5.1 million and $3.0 million in the three months ended March 31, 2021 and 2020, respectively. These amounts are included as components of both Cost of revenue and Operating expenses in our condensed consolidated statements of operations.

See "Results of Operations" in this MD&A for a discussion of the changes in our revenue and expenses for the three months ended March 31, 2021 compared to the three months ended March 31, 2020.

Restructuring and Cost Reduction Initiatives

2020 Restructuring Initiative. In 2020, we implemented a restructuring plan to eliminate certain positions and redundant facilities, primarily in connection with the ECI Acquisition, to further streamline our global footprint and improve our operations (the "2020 Restructuring Initiative"). In connection with this initiative, we expect to eliminate duplicate functions arising from the ECI Merger and support our efforts to integrate the two companies. The 2020 Restructuring Initiative includes facility consolidations and a reduction in workforce, including three former executives of ECI for whom severance aggregating $1.1 million was recorded in the three months ended March 31, 2020.

In connection with the 2020 Restructuring Initiative, we recorded restructuring and related expense of $0.4 million and $1.1 million in the three months ended March 31, 2021 and 2020, respectively. The amount recorded in the three months ended March 31, 2021 was comprised of $0.7 million for severance and related costs for approximately 10 employees and $0.4 million for variable costs related to restructured facilities, offset by a credit of $0.7 million for changes in estimate related to amounts previously recorded. The amount recorded in the three months ended March 31, 2020 represented severance for three former executives of ECI. We expect that the amounts related to severance will be paid in 2021. We expect to record additional restructuring and related expense approximating $4 million under the 2020 Restructuring Initiative in the aggregate for severance and planned facility consolidations.

2019 Restructuring Initiative. In June 2019, we implemented a restructuring plan to further streamline our global footprint, improve our operations and enhance our customer delivery (the "2019 Restructuring Initiative"). The 2019 Restructuring Initiative includes facility consolidations, refinement of our research and development activities, and a reduction in workforce. In connection with this initiative, we expect to reduce our focus on hardware and hardware-based development over time and to increase our development focus on software virtualization, functional simplicity and important customer requirements. The facility consolidations under the 2019 Restructuring Initiative (the "Facilities Initiative") include a consolidation of our North Texas sites into a single campus, housing engineering, customer training and support, and administrative functions, as well as a reduction or elimination of certain excess and duplicative facilities worldwide. In addition, we are substantially consolidating our global software laboratories and server farms into two lower cost North American sites. We continue to evaluate our properties included in the Facilities Initiative for accelerated amortization and/or right-of-use asset impairment. We expect that the actions under the Facilities Initiative will be completed in 2021.

In connection with the 2019 Restructuring Initiative, we recorded restructuring and related expense of $5.6 million and $1.0 million in the three months ended March 31, 2021 and 2020, respectively. The amount recorded in the three months ended March 31, 2021 related to facilities. The amount recorded in the three months ended March 31, 2020 was comprised of $0.7 million for severance and related costs for five employees and $0.3 million related to facilities. We expect that we will record nominal, if any, additional restructuring and related expense related to severance and related costs under the 2019 Restructuring Initiative.

Accelerated Rent Amortization. Accelerated rent amortization is recognized from the date that we commence the plan to fully or partially vacate a facility, for which there is no intent or ability to enter into a sublease, through the final vacate date. We recorded $3.4 million and $0.1 million for accelerated rent amortization in the three months ended March 31, 2021 and 2020, respectively, in connection with our 2019 Restructuring Initiative. These amounts are included as components of Restructuring and related expense. We continue to evaluate our properties included in the Facilities Initiative for accelerated amortization and/or right-of-use asset impairment. We may incur additional future expense if we are unable to sublease other locations included in the Facilities Initiative.

Critical Accounting Policies and Estimates

Management's discussion and analysis of financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates and judgments on historical experience, knowledge of current conditions and beliefs of what could occur in the future given available information. We consider the following accounting policies to be both those most important to the portrayal of our financial condition and those that require the most subjective judgment: revenue recognition, the valuation of inventory, the valuation of the Debentures and Warrants received as sale consideration in connection with the Kandy Sale, warranty accruals, loss contingencies and reserves, stock-based compensation, business combinations, goodwill and intangible assets, accounting for leases, and accounting for income taxes. If actual results differ significantly from management's estimates and projections, there could be a material effect on our condensed consolidated
43


financial statements. There were no significant changes to our critical accounting policies from January 1, 2021 through March 31, 2021. For a further discussion of our other critical accounting policies and estimates, please refer to our Annual Report on Form 10-K for the year ended December 31, 2020.

The increase in our product revenue in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily the result of the inclusion of approximately $26 million of higher product revenue attributable to our IP Optical Networks segment in the current year quarter, in part due to the inclusion of IP Optical Networks revenue for the full quarter, compared to only one month of revenue in the three months ended March 31, 2020. The decrease in revenue in our Cloud and Edge segment was primarily attributable to lower sales of our on-premise Enterprise Edge SBC products and the loss of revenue due to the Kandy Sale, partially offset by higher revenue from sales of certain of our software applications.

Revenue from indirect sales through our channel partner program was 21% and 38% of our product revenue in the three months ended March 31, 2021 and 2020, respectively. In the three months ended March 31, 2021, 23% of our product revenue was attributable to sales to enterprise customers, compared to 36% in the three months ended March 31, 2020. These sales were made through both our direct sales team and indirect sales channel partners.

The timing of the completion of customer projects and revenue recognition criteria satisfaction may cause our product revenue to fluctuate from one period to the next.

Service revenue is primarily comprised of hardware and software maintenance and support (“maintenance revenue”) and network design, installation and other professional services (“professional services revenue”).

Service revenue for the three months ended March 31, 2021 and 2020 was comprised of the following (in thousands, except percentages):

  Total service revenue$75,270 $19,613 $94,883 $73,821 $8,262 $82,083 


The increase in maintenance revenue in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily attributable to the inclusion of a full quarter of IP Optical Networks segment sales, compared to only one month of revenue in the three months ended March 31, 2020. The increase in professional services revenue was partially attributable to the inclusion of approximately $3 million of higher professional services revenue attributable to a full quarter of IP Optical Networks segment sales in the current year quarter, compared to only one month of revenue in the three months ended March 31, 2020, coupled with approximately $2 million of higher professional services revenue attributable to our Cloud and Edge segment.

* Represents less than 10% of total revenue.


Revenue from customers domiciled outside the United States was 59% and 50% of revenue in the three months ended March 31, 2021 and 2020, respectively. Due to the timing of project completions, we expect that the domestic and international components as a percentage of revenue may fluctuate from quarter to quarter and year to year. In addition, as a result of the ECI Acquisition, we expect that the domestic and international revenue as a percentage of revenue in future periods will change, as virtually all of ECI's revenue has historically been recognized from customers outside the United States.

Our deferred product revenue was approximately $6 million and $8 million at March 31, 2021 and December 31, 2020, respectively. Our deferred service revenue was approximately $119 million and $115 million at March 31, 2021 and December 31, 2020, respectively. Our deferred revenue balance may fluctuate because of the timing of revenue recognition, customer payments, maintenance contract renewals, contractual billing rights and maintenance revenue deferrals included in multiple element arrangements.

We expect that our total revenue in 2021 will increase compared to 2020 as a result of both increased customer spend and continued cross-selling opportunities.

Cost of Revenue/Gross Margin. Our cost of revenue consists primarily of amounts paid to third-party manufacturers for purchased materials and services, royalties, inventory valuation adjustments, warranty costs, and manufacturing and services personnel and related costs. Our cost of revenue and gross margins for the three months ended March 31, 2021 and 2020 were as follows (in thousands, except percentages):

The increase in our product gross margin in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily due to margin improvement in our Cloud and Edge segment. The increase in product gross margin of our Cloud and Edge segment was primarily attributable to customer and product mix, and to a lesser extent, the impact of the Kandy Sale.

The decrease in our service gross margin in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily due to the inclusion of a full quarter of our IP Optical Networks segment's historically lower service gross margin for the full quarter, coupled with higher installation costs.

We believe that our total gross margin will decrease slightly in 2021 compared to 2020, primarily due to higher expected sales from IP Optical Networks, which have historically lower margins due to the higher hardware content in their products.

Research and Development Expenses. Research and development expenses consist primarily of salaries and related personnel expenses and prototype costs for the design, development, testing, and enhancement of our products. Research and development expenses for the three months ended March 31, 2021 and 2020 were as follows (in thousands, except percentages):

The increase in research and development expenses in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily attributable to the inclusion of a full quarter of IP Optical Networks expense,
46


compared to only one month of expense in the three months ended March 31, 2020, which added approximately $13 million in research and development expenses, principally employee-related. This increase was partially offset by approximately $8 million of lower expenses in our Cloud and Edge segment, primarily lower employee-related, third-party consulting and infrastructure-related expenses due to our previous cost reduction and restructuring initiatives and the impact of the Kandy Sale.

Some aspects of our research and development efforts require significant short-term expenditures, the timing of which may cause significant variability in our expenses. We believe that rapid technological innovation is critical to our long-term success, and we are tailoring our investments to meet the requirements of our customers and market. We believe that our research and development expense in 2021 will increase compared to 2020, primarily due to incremental investment in our IP Optical Networks segment to address the global market opportunity.

Sales and Marketing Expenses. Sales and marketing expenses primarily consist of salaries and related personnel costs, commissions, travel and entertainment expenses, promotions, customer trial and evaluations inventory, and other marketing and sales support expenses. Sales and marketing expenses for the three months ended March 31, 2021 and 2020 were as follows (in thousands, except percentages):

The increase in sales and marketing expenses in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily attributable to the inclusion of a full quarter of IP Optical Networks expense, compared to only one month of expense in the three months ended March 31, 2020, which added approximately $10 million in sales and marketing expenses, principally employee-related expenses. This increase was partially offset by approximately $4 million of lower costs in our Cloud and Edge segment, principally employee- and infrastructure-related, arising from our previous cost reduction and restructuring initiatives.

We believe that our sales and marketing expenses will increase modestly in 2021 compared with 2020, primarily due to higher employee-related expenses and higher costs, assuming COVID-19 restrictions continue to ease.

General and Administrative Expenses. General and administrative expenses consist primarily of salaries and related personnel costs for executive and administrative personnel, and audit, legal and other professional fees. General and administrative expenses for the three months ended March 31, 2021 and 2020 were as follows (in thousands, except percentages):

The decrease in general and administrative expenses in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily attributable to the absence in the current year quarter of approximately $3 million of litigation-related expense in our Cloud and Edge segment, coupled with approximately $1 million of lower other Cloud and Edge expenses. These reductions were partially offset by higher expense due to the inclusion of a full quarter of IP Optical Networks expense in the current year quarter, compared to only one month of expense in the three months ended March 31, 2020, which added approximately $2 million in general and administrative expenses, principally employee-related.

We believe that our general and administrative expenses in 2021 will be consistent with our 2020 levels and decline in future years as we realize additional integration synergies.

Amortization of Acquired Intangible Assets. Amortization of acquired intangible assets for the three months ended March 31, 2021 and 2020 was as follows (in thousands, except percentages):

The increase in amortization of acquired intangible assets in the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily due to expense related to the inclusion of a full quarter of amortization of the intangible assets arising from the ECI Acquisition, compared to only one month of such amortization in the three months ended March 31, 2020. Amortization of acquired intangible assets is reported separately in the condensed consolidated statements of operations.

Acquisition-, Disposal- and Integration-Related Expenses. Acquisition-, disposal- and integration-related expenses include those expenses related to acquisitions that we would otherwise not have incurred. Acquisition- and disposal-related expenses include professional and services fees, such as legal, audit, consulting, paying agent and other fees. Integration-related expenses represent incremental costs related to combining our systems and processes with those of acquired businesses, such as third-party consulting and other third-party services.

We recorded $1.2 million of acquisition-, disposal- and integration-related expenses in the three months ended March 31, 2021, comprised of $0.2 million of disposal-related fees incurred in connection with the Kandy Sale and $1.0 million of integration-related expenses, primarily related to the ECI Acquisition.

We recorded $12.4 million of acquisition-, disposal- and integration-related expenses in the three months ended March 31, 2020, virtually all of which was for professional fees primarily in connection with the ECI Acquisition.

Acquisition-, disposal- and integration-related expenses are reported separately in the consolidated statements of operations.

Restructuring and Related Expense. We have been committed to our streamlining operations and reducing operating costs by closing and consolidating certain facilities and reducing our worldwide workforce. Please see the additional discussion of our restructuring initiatives in the "Restructuring and Cost Reduction Initiatives" section of the Overview of this MD&A.

We recorded restructuring and related expense of $6.0 million in the three months ended March 31, 2021, comprised of $5.3 million related to facilities and $0.7 million for severance and related expenses. We recorded $2.1 million in the three months ended March 31, 2020, comprised of $1.8 million for severance and related expenses $0.3 million related to facilities.

Although we have eliminated positions as part of our restructuring initiatives, we continue to hire in certain areas that we believe are important to our future growth. Restructuring and related expense is reported separately in the condensed consolidated statements of operations.

Interest income in the three months ended March 31, 2021 was primarily due to the paid-in-kind interest on the Debentures, which was recorded as an increase to the fair value of the Debentures. Interest expense in the three months ended March 31, 2021 was comprised of interest and debt issuance costs in connection with the 2020 Credit Facility (as defined below), including the write-off of $2.5 million of capitalized debt insurance costs in connection with the Third Amendment (as defined below), coupled with interest on finance leases.

Interest income in the three months ended March 31, 2020 primarily represents interest earned on the outstanding note receivable arising from litigation that was settled in 2019. Interest expense in the three months ended March 31, 2020 was comprised of interest and debt issuance costs in connection with the 2020 Credit Facility, the write-off of debt issuance costs in connection with the retirement of the 2019 Credit Facility and interest on other borrowings and finance leases.

Income Taxes. We recorded provisions for income taxes of $0.8 million and $0.2 million in the three months ended March 31, 2021 and 2020, respectively. These amounts reflect our estimates of the effective rates expected to be applicable for the respective full fiscal years, adjusted for any discrete events, which are recorded in the period that they occur. These estimates are reevaluated each quarter based on our estimated tax rate for the full fiscal year. The estimated effective tax rate includes the impact of valuation allowances in various jurisdictions.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have a current or future material effect on our financial position, changes in financial position, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Our cash and restricted cash aggregated $109 million at March 31, 2021. We had cash and restricted cash of $136 million at December 31, 2020. These amounts included cash and restricted cash aggregating approximately $39 million at March 31, 2021 and $46 million at December 31, 2020 held by our non-U.S. subsidiaries. If we elected to repatriate all excess funds held by our non-U.S. subsidiaries as of March 31, 2021, we do not believe that the amounts of potential withholding taxes that would arise from the repatriation would have a material effect on our liquidity.

We currently maintain the Senior Secured Credit Facilities Credit Agreement (as amended, the "2020 Credit Facility"), by and among us, as a guarantor, Ribbon Communications Operating Company, Inc., as the borrower ("Borrower"), Citizens Bank, N.A. ("Citizens"), as administrative agent, a lender, issuing lender, swingline lender, joint lead arranger and bookrunner, Santander Bank, N.A., as a lender, joint lead arranger and bookrunner, and the other lenders party thereto (each, together with Citizens Bank, N.A. and Santander Bank, N.A., referred to individually as a "Lender", and collectively, the "Lenders"). For additional details regarding the terms of the 2020 Credit Facility, see Note 10 - Debt to our condensed consolidated financial statements.

On March 3, 2021 (the "Third Amendment Effective Date"), we entered into a Third Amendment to Credit Agreement (the "Third Amendment"), which further amended the 2020 Credit Facility. The Third Amendment provided for an incremental term loan facility to us in the original principal amount of $74.6 million, the proceeds of which were used on the Third Amendment Effective Date to consummate an open market purchase of all outstanding amounts under the Term B Loan. Upon the consummation of the open market purchase, the Term B Loans were assigned to the Borrower and immediately canceled, such that the outstanding amount under the Term A Loan and incremental term loan facility were combined and held by the Lenders (the "2020 Term Loan"). We are required to make quarterly principal payments on the 2020 Term Loan aggregating approximately $20 million per year in the first three years and $30 million in the fourth year, with the final payment approximating $300 million due on the maturity date.

49


At March 31, 2021, we had an outstanding 2020 Term Loan balance of $390.6 million at an average interest rate of 3.40% and $6.4 million of letters of credit outstanding with an interest rate of 2.50%. We were in compliance with all covenants of the 2020 Credit Facility at both March 31, 2021 and December 31, 2020.

We are exposed to financial market risk related to foreign currency fluctuations and changes in interest rates. These exposures are actively monitored by management. To manage the volatility related to the exposure to changes in interest rates, we have entered into a derivative financial instrument. Management's objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in interest rates. Our policies and practices are to use derivative financial instruments only to the extent necessary to manage exposures. We do not hold or issue derivative financial instruments for trading or speculative purposes.

As a result of exposure to interest rate movements, during March 2020, we entered into an interest rate swap arrangement, which effectively converted our $400 million term loan with its variable interest rate based upon one-month LIBOR to an aggregate fixed rate of 0.904%, plus a leverage-based margin as defined in the 2020 Credit Facility. The notional amount of this swap as of March 31, 2021 was $400 million, and the swap matures on March 3, 2025, the same date the 2020 Credit Facility matures.

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we are using an interest rate swap as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) in the condensed consolidated balance sheet and is subsequently reclassified into earnings in the period that the hedged forecasted transactions affect earnings. During the three months ended March 31, 2021 and 2020, such a derivative was used to hedge the variable cash flows associated with the 2020 Credit Facility. Any ineffective portion of the change in fair value of the derivative would be recognized directly in earnings. However, during the three months ended March 31, 2021 and 2020, we recorded no hedge ineffectiveness.

Amounts reported in accumulated other comprehensive income (loss) related to our derivative will be reclassified to interest expense as interest is accrued on our variable-rate debt. Based upon projected forward rates, we estimate as of March 31, 2021 that $3.1 million may be reclassified as an increase to interest expense over the next 12 months.

From time to time, we enter into uncommitted and unsecured short-term loans to finance exports in China. We did not have any such short-term loans outstanding at March 31, 2021 and December 31, 2020.

We use letters of credit, performance and bid bonds in the course of our business. At March 31, 2021, we had bank guarantees, performance and bid bonds under various uncommitted facilities (collectively, the "Guarantees") aggregating $26.9 million, and $6.4 million of letters of credit under the 2020 Credit Facility (the "Letters of Credit"). At December 31, 2020, we had Guarantees aggregating $27.0 million and $5.6 million of Letters of Credit. At both March 31, 2021 and December 31, 2020, we had cash collateral of $2.7 million supporting the Guarantees, which are included in Restricted cash in our condensed consolidated balance sheets.

In the second quarter of 2019, our Board of Directors (the "Board") approved a stock repurchase program pursuant to which we may repurchase up to $75 million of the Company's common stock prior to April 18, 2021. Repurchases under the program could be made in the open market, in privately negotiated transactions or otherwise, with the amount and timing of repurchases depending on the market conditions and corporate discretion. This program did not obligate us to acquire any particular amount of common stock and the program could be extended, modified, suspended or discontinued at any time at the Board's discretion. We did not repurchase any shares during the three months ended March 31, 2021 or the year ended December 31, 2020. At both March 31, 2021 and December 31, 2020, we had $70.5 million remaining under the Repurchase Program for future repurchases. The Repurchase Program expired on April 18, 2021.

Cash Flows from Operating Activities

Our operating activities used $6.2 million in the three months ended March 31, 2021 and provided $39.9 million of cash in the three months ended March 31, 2020.

50


Cash used in operating activities in the three months ended March 31, 2021 was primarily the result of our net loss and lower accrued expenses and other long-term liabilities, as well as lower accounts payable. These amounts were partially offset by lower accounts receivable higher and other operating assets and higher deferred revenue, coupled with our non-cash expenses, such as the decrease in the fair value of investments recorded in connection with the Kandy Sale, amortization of intangible assets, stock-based compensation, depreciation and amortization of property and equipment, and amortization of debt issuance costs. Our lower accounts receivable was primarily due to the collection in the quarter of seasonally higher amounts outstanding at December 31, 2020. The decrease in accrued expenses and other long-term liabilities was primarily due to the cash payments in the quarter related to our employee cash bonus program.

Cash provided by operating activities in the three months ended March 31, 2020 was primarily the result of lower accounts receivable and inventory, coupled with higher accrued expenses and other long-term liabilities, and deferred revenue. These amounts were partially offset by our net loss, non-cash activities, lower accounts payable and higher other operating assets. Our lower accounts receivable was due to the collection in the quarter of seasonally higher amounts outstanding at December 31, 2019.

Cash Flows from Investing Activities

Our investing activities used $5.4 million of cash in the three months ended March 31, 2021 to purchase property and equipment.

Our investing activities used $309.4 million of cash in the three months ended March 31, 2020, comprised of $346.9 million of cash paid as cash consideration for ECI and $6.0 million of investments in property and equipment. These amounts were partially offset by $43.5 million of cash proceeds from the sale of land in connection with the ECI Acquisition.

Cash Flows from Financing Activities

Our financing activities used $14.8 million of cash in the three months ended March 31, 2021, primarily due to $74.6 million of proceeds from the incremental loan obtained in connection with the Third Amendment, which amount was used to consummate an open market purchase of all outstanding amounts under the Term B Loan, $11.2 million for the payment of tax withholding obligations related to the net share settlement of restricted stock awards upon vesting, and $77.1 million of principal payments of term debt, including the $74.6 million payoff of the Term B Loan in connection with the Third Amendment, $0.8 million of payments of debt issuance costs and $0.3 million for principal payments of finance leases.

Our financing activities provided $335.1 million of cash in the three months ended March 31, 2020, primarily due to $403.0 million of proceeds from term debt, which was comprised of $400.0 million of proceeds from the 2020 Credit Facility and $3.5 million of proceeds from short-term loans in China for the financing of certain export activities. These proceeds were partially offset by the repayment of amounts outstanding under the 2019 Credit Facility aggregating $56.7 million at the time we entered into the 2020 Credit Facility, $10.6 million for the payment of debt issuance costs in connection with the 2020 Credit Facility, $0.8 million for the payment of tax withholding obligations related to the net share settlement of restricted stock awards upon vesting and $0.3 million for principal payments of finance leases.

Based on our current expectations, we believe our current cash and available borrowings under the 2020 Credit Facility will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least twelve months. The rate at which we consume cash is dependent on the cash needs of our future operations. We anticipate devoting substantial capital resources to continue our research and development efforts, to maintain our sales, support and marketing, to complete acquisition-related integration activities and for other general corporate activities. We further believe that our financial resources, along with managing discretionary expenses, will allow us to manage the anticipated impact of the COVID-19 pandemic on our business operations. Looking ahead, we have developed contingency plans to reduce costs further if the situation continues to deteriorate. The challenges posed by the COVID-19 pandemic on our business continue to evolve rapidly. Consequently, we continue to evaluate our financial position in light of future developments, particularly those relating to the COVID-19 pandemic. However, it is difficult to predict future liquidity requirements with certainty, and our cash and available borrowings under the 2020 Credit Facility may not be sufficient to meet our future needs, which would require us to refinance our debt and/or obtain additional financing. We may not be able to refinance our debt or obtain additional financing on favorable terms or at all.

Recent Accounting Pronouncements

The Financial Accounting Standards Board ("FASB") issued the following accounting pronouncement which became effective for us in 2021, and which did not have a material impact on our condensed consolidated financial statements:

The FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"), which modifies ASC 740 to simplify the accounting for income taxes. ASU 2019-12 addresses the accounting for hybrid tax regimes, tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of legal entities not subject to tax, intraperiod tax allocation exception to incremental approach, ownership changes in investments - changes from a subsidiary to an equity method investment, ownership changes in investments - changes from an equity method investment to a subsidiary, interim period accounting for enacted changes in tax law and year-to-date loss limitation in interim period tax accounting.

The FASB issued the following accounting pronouncement, which we do not believe will have a material impact on our condensed consolidated financial statements upon adoption:

In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope ("ASU 2021-01"), which refines the scope of Accounting Standards Codification 848, Reference Rate Reform ("ASC 848") and clarifies some of its guidance as part of the FASB's monitoring of global reference rate reform activities. ASU 2021-01 permits entities to elect certain optional expedients and exceptions when accounting for derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, for computing variation margin settlements, and for calculating price alignment interest in connection with reference rate reform activities under way in global financial markets (the "discounting transition"). ASU 2021-01 is effective for us prospectively in any period through December 31, 2022 that a modification is made to the terms of the derivatives affected by the discounting transition.


Item 3.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risk related to foreign currency fluctuations and changes in interest rates. Except as presented below, there have been no material changes in market risk from the information provided in Item 7A. Quantitative and Qualitative Disclosures About Market Risk of our Annual Report on Form 10-K, for the year ended December 31, 2020.

To manage the volatility related to the exposure to changes in interest rates, we have entered into a derivative financial instrument. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in interest rates. Our policies and practices are to use derivative financial instruments only to the extent necessary to manage exposures. We do not hold or issue derivative financial instruments for trading or speculative purposes.

Amounts reported in accumulated other comprehensive income (loss) related to our derivative will be reclassified to interest expense as interest is accrued on our variable-rate debt. The fair value of our derivative was a liability of $4.3 million at March 31, 2021. Based upon projected forward rates, we estimate as of March 31, 2021 that $3.1 million may be reclassified as an increase to interest expense over the next twelve months.


Item 4.    Controls and Procedures

Disclosure Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

Dear Patrick,

On behalf of Ribbon Communications Inc. (“Ribbon”) and Sonus Networks, Inc. d/b/a Ribbon Communications Operating Company, Inc. (“RCOC” and Ribbon and RCOC, together with its affiliates who may employ you from time to time, the “Company”), I am pleased to provide you with this written offer of employment (this “Agreement”) as Ribbon’s Chief Legal Officer and Secretary, effective as of June 1, 2020 (the “Start Date”).

In the event that your employment is terminated by the Company for Cause or as a result of your resignation for any reason, in each case, prior to the first (1st) anniversary of the Relocation Date or you fail to timely relocate in accordance with this Section 1(d), you will be required to reimburse the Company for the Relocation Allowance within thirty (30) days following your termination of employment or the date of such failure, as applicable.

3.    Employment Relationship. The Company’s obligations under this Agreement are contingent upon your satisfactory completion of our pre-employment reference check and background check investigation and your verification of your identity and employment eligibility. No provision of this Agreement shall be construed to create an express or implied employment contract for a specific period of time. Employment at the Company is considered “at will” and either you or the Company may terminate the employment relationship at any time and for any reason, subject to compliance with the Severance Agreement. As a full-time employee of the Company, you will be expected to devote your full business time and energies to the business and affairs of the Company.

4.    Termination and Eligibility for Severance. The parties acknowledge and agree that they will enter into a severance agreement in substantially the form attached hereto as Attachment 1 (the “Severance Agreement”) on the Start Date. Except as set forth in the Severance Agreement, you will not be entitled to any severance or other termination payments or benefits from the Company or any of its affiliates.
5.    Previous Employment.

This attached agreement must be signed and returned to the Company as soon as practicable following the Start Date.

7.            Indemnity.  As an executive of the Company, the Company will provide you with an Indemnity Agreement on the Company’s standard form.

3.The fees and expenses of the arbitration will be borne as provided in the AAA Costs of Arbitration section, and each party will bear the fees and expenses of its own attorney, unless the arbitrator finds that a statutory award of attorneys’ fees and/or costs is appropriate.

4.The parties waive their rights to a class or collective action. The parties agree that claims may not be joined, consolidated, or heard together with claims of any other current or former employee of the Company or other third party.

5.The parties agree that this Section 8(g) has been included to resolve any disputes between them with respect to this Agreement or your employment, and that this Section 8(g) will be grounds for dismissal of any court action commenced by either party with respect to this Agreement, other than post-arbitration actions seeking to enforce an arbitration award or actions seeking an injunction or temporary restraining order and other than claims for unemployment insurance benefits or workers compensation benefits or other claims which by law cannot be subject to a mandatory arbitration agreement.  In the event that any court determines that this arbitration procedure is not binding, or otherwise allows any litigation regarding a dispute, claim, or controversy covered by this Agreement to proceed, the parties hereto hereby waive, to the maximum extent allowed by law, any and all right to a class or collection action or a trial by jury in or with respect to such litigation.

6.The parties will keep confidential, and will not disclose to any person, except as may be required by law or the rules and regulations of the Securities and Exchange Commission or other government agencies, the existence of any controversy hereunder, the referral of any such controversy to arbitration or the status or resolution thereof; notwithstanding the foregoing, nothing herein shall restrict you from communicating with a government agency or engaging in protected concerted activity that cannot be waived by such an agreement not to disclose.

(h)This Agreement shall be governed by and interpreted in accordance with the laws of the State of Delaware, without regard to the conflict of laws provisions thereof or of any other jurisdiction.

(i)The Company is an equal opportunity employer.

Attachment 2
Confidentiality, Non-Competition, Non-Solicitation
And Assignment of Inventions Agreement
In consideration for my employment by Ribbon Communications Inc. (“Ribbon”) and Sonus Networks, Inc. d/b/a Ribbon Communications Operating Company, Inc., a wholly owned subsidiary of Ribbon Communications Inc., (“RCOC” and together with Ribbon, the “Company”), the promises the Company makes in this Confidentiality, Non-Competition, Non-Solicitation and Assignment of Inventions Agreement (the “Agreement”), and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the Company as follows:
1.Recognition of Company’s Rights; Non-Disclosure. I understand and acknowledge that the Company possesses Proprietary Information (defined below), which the Company agrees to disclose to me in exchange for my covenants under this Agreement. I acknowledge and agree that the Company’s Proprietary Information (1) is secret and not a matter of knowledge in the industry; (2) gives the Company an advantage over competitors who do not know or use the Proprietary Information; (3) is of such value and nature as to make it reasonable and necessary to protect and preserve the confidentiality and secrecy of the Proprietary Information; and (4) is a valuable and special and unique asset of the Company, the disclosure of which could cause substantial injury and loss of profits and goodwill to the Company. At all times during the term of my employment and thereafter, I will hold in strictest confidence and will not disclose, use, lecture upon, or publish any of the Company’s Proprietary Information, directly or indirectly, at any time in the future except as such disclosure, use, or publication may be required in connection with my work for the Company, or unless an executive member of the Company or the Board of Directors of the Company expressly authorizes such disclosure in writing. I understand that notwithstanding the foregoing, nothing in this Agreement prohibits me from communicating with government agencies or participating in government agency investigations or proceedings, and nothing herein limits my right to receive an award for information provided to the Securities and Exchange Commission. I understand that I am not required to notify the Company of any such communications; provided however, that nothing herein authorizes the disclosure of information I obtained through a communication that was subject to attorney client privilege.
I hereby assign to the Company any rights I may have or acquire in the Company’s Proprietary Information and recognize that all Proprietary Information shall be the sole property of the Company and its assigns and in any event must be returned to the Company upon my separation date, and that the Company and its assigns shall be the sole owner of all patent rights, copyrights, trade secret rights, and all other rights throughout the world (collectively, “Proprietary Rights”) in connection therewith.

The term “Proprietary Information” shall mean trade secrets, confidential knowledge, data, or any other proprietary information of the Company and each of its subsidiaries or affiliated companies. By way of illustration but not limitation, “Proprietary Information” includes (a) inventions, trade secrets, ideas, processes, formulas, data, programs, other works of authorship, know-how, improvements, discoveries, developments, designs, and techniques relating to the business or proposed business of the Company and that were learned or discovered by me during the term of my employment with the Company; (b) information regarding plans for research, development, new products and services, marketing and selling, business plans, budgets and unpublished financial statements, licenses, prices and costs, suppliers, and customers that were learned or discovered by me during the term of my employment with the Company; and (c) information regarding the skills and compensation of other employees of the Company. Proprietary Information does not include information that (i) is or becomes known to the public, other than as a result of my disclosure in violation of this Agreement or of any other person’s breach of a legal or contractual obligation to the Company, or (ii) was known by me prior to my employment with the Company and not as a result of anyone else’s breach of a legal or contractual obligation.

I understand and acknowledge that my non-disclosure obligations described above are subject to the following immunity provisions of the Defend Trade Secrets Act of 2016:
2

|US-DOCS\115300498.9||


I.Immunity. An individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that:

(A)is made
(a)in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and
(b)solely for the purpose of reporting or investigating a suspected violation of law; or

(B)is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.
II.Use of Trade Secret Information in an Anti-Retaliation Lawsuit. An individual who files a lawsuit for retaliation by the Company for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual:

(A)files any document containing the trade secret under seal; and
(B)does not disclose the trade secret, except pursuant to court order.

2.Specialized Training and Knowledge. During my employment the Company will provide me with specialized training and knowledge regarding the Company’s Proprietary Information as well as regarding the Company’s specific operations, products and services. I recognize the value of this training and knowledge and agree that it is a material benefit to me. I acknowledge and agree that I have not previously received this training and knowledge from the Company, and that I would not receive this training and knowledge from the Company but for my signing of this Agreement.
3.Third Party Information. I understand, in addition, that the Company may from time to time receive from third parties confidential or proprietary information (“Third Party Information”) subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes. During the term of my employment and thereafter, I will hold Third Party Information in the strictest confidence and will not disclose (to anyone other than Company personnel who need to know such information in connection with their work for the Company) or use, directly or indirectly, at any time in the future, except in connection with my work for the Company, Third Party Information unless expressly authorized by an executive officer of the Company in writing.
4.Assignment of Intellectual Property.
(a) I hereby assign to the Company all my right, title, and interest in and to any and all inventions, original works of authorship (including software source code), trade secrets, designs, developments, improvements, concepts and other intellectual property (and all Proprietary Rights with respect thereto) (collectively, “Intellectual Property”), whether or not patentable or registrable under patent, copyright or similar statutes, that were made or conceived or reduced to practice or learned by me, either alone or jointly with others, (i) at the direction of the Company, (ii) during the performance of my duties of employment, (iii) on Company time, (iv) using Company’s equipment, materials, supplies, facilities or Proprietary Information, or (v) that, at the time of conception, authorship, development, or reduction to practice of the Intellectual Property, relate to the business of the Company as conducted (or as proposed to be conducted) or the actual or demonstrably anticipated research or development of the Company, during the period of my employment with the Company. The only Intellectual Property excluded from this provision are those which are set forth in Exhibit A to this Agreement, or the assignment of which are prohibited pursuant to applicable law. I have attached, as Exhibit A, a list specifically describing all inventions, original works of authorship (including software source code), trade secrets, designs, developments, improvements, concepts, and other intellectual property that:

3




(i)I made, alone or jointly with others, prior to employment with Company;
(ii)belong to me, in which I have an ownership interest, or which are owned in whole or in part by another company, organization, or other entity of which I have an ownership interest; and
(iii)are not assigned to Company (collectively, “Retained Intellectual Property”);

provided that if no such list is attached, I represent that there is no such Retained Intellectual Property.

To preclude any possible uncertainty, I have also set forth on Exhibit A attached hereto a complete list of all inventions that I have, alone or jointly with others, conceived, developed, or reduced to practice or caused to be conceived, developed, or reduced to practice prior to commencement of my employment with the Company, in which I have assigned my ownership interest to a third party and that I wish to have excluded from the scope of this Agreement; provided that if no such list is attached, I represent that there are no such inventions. If disclosure of any such invention on Exhibit A would cause me to violate any prior confidentiality agreement, I understand that I am not to list such inventions in Exhibit A but am to describe such invention with as much specificity as possible without violating any prior agreement and state that additional information has been withheld for that reason.

All Intellectual Property assigned to the Company by this Section 4 is hereinafter referred to as “Company Intellectual Property.”

(b)If in the course of my employment with the Company, the Company incorporates into any Company product, process or machine any Retained Intellectual Property, I hereby grant and the Company shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license to make, have made, modify, create derivative works of, improve, use, import, export, and sell such Retained Intellectual Property as part of or in connection with such product, process or machine. I agree to and do hereby assign to Company any and all right, title, and interest in and to any and all modifications, improvements, and other derivative works made by or on behalf of Company to any such Retained Intellectual Property that is licensed to Company pursuant to this Section 4, and thus any and all such modifications, improvements, and other derivative works are deemed Company Intellectual Property.
(c)I acknowledge that all original works of authorship that are made by me (solely or jointly with others) during the term of my employment with the Company and that are within the scope of my employment and protectable by copyright (“Works”) are “works made for hire,” as that term is defined in the United States Copyright Act (17 U.S.C. § 101). If for any reason any such Works or any part thereof would not or cannot be considered a “work made for hire” under applicable law, I agree to and do hereby sell, assign, and transfer to Company, its successors and assigns, the entire right, title and interest in and to the copyright in such Work and any registrations and copyright applications relating thereto and any renewals and extensions thereof, and in and to all works based upon, derived from, or incorporating that Work, and in and to all income, royalties, damages, claims and payments now or hereafter due or payable with respect thereto, and in and to all causes of action, either in law or in equity for past, present, or future infringement based on the copyrights, and in and to all rights corresponding to the foregoing throughout the world. I hereby waive, as against Company, its successors, assigns and licensees, all moral rights which I have or acquire in respect of all such Works. I agree to enforce the moral rights as against others as directed by and at the cost of Company or its successor-in-title of the copyright in the Works.
(d)I acknowledge and agree that the Company is not obligated to commercialize any Company Intellectual Property, and that if I desire to independently commercialize any of said Company Intellectual Property, I must request and obtain a written license from the Company beforehand, which license request may be declined by the Company in its sole discretion.
5.Enforcement of Proprietary Rights. During my employment and after my separation from the Company for any reason whatsoever, I agree that I will assist the Company in every proper way to obtain and from time to time enforce United States and foreign Proprietary Rights relating to Company Intellectual Property, including without limitation inventions, in any and all countries. To that end I will execute, verify,
4




and deliver such documents and perform such other acts (including appearances as a witness) as the Company may reasonably request for use in applying for, obtaining, perfecting, evidencing, sustaining, and enforcing such Proprietary Rights and the assignment thereof. In addition, I will execute, verify, and deliver assignments of such Proprietary Rights to the Company or its designee. My obligation to assist the Company with respect to Proprietary Rights relating to such Company Inventions in any and all countries shall continue beyond the termination of my employment, but the Company shall compensate me at a reasonable rate after my termination for the time actually spent by me at the Company’s request on such assistance. In addition, the Company will provide me with reasonable notice of the need for assistance when feasible and agrees to schedule such assistance in such a manner as not to interfere with any alternative employment obtained by me when possible.
In the event the Company is unable for any reason, after reasonable effort, to secure my signature on any document needed in connection with the actions specified in the preceding paragraph, I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for and in my behalf to execute, verify, and file any such documents and to do all other lawfully permitted acts to further the purposes of the preceding paragraph thereon with the same legal force and effect as if executed by me. I hereby waive and quitclaim to the Company any and all claims, of any nature whatsoever, that I now or may hereafter have for infringement of any Proprietary Rights assigned hereunder to the Company.

6.Obligation to Keep Company Informed. During the period of my employment, I will promptly disclose to the Company fully and in writing and will hold in trust for the sole right and benefit of the Company any and all Company Intellectual Property, including without limitation inventions. In addition, I will disclose all patent applications filed by me during the three (3) years after termination of my employment with the Company.
7.Other Activities; Non-Solicitation; Non-Compete; Non-Disparagement. In consideration of my employment with the Company and terms and conditions of the employment letter to which this Agreement is attached and for the Company’s promises to disclose its Proprietary Information to me and to provide me with specialized training and knowledge, and as part of the agreement between the Company and me regarding the Company disclosing its Proprietary Information to me and providing me with specialized training and knowledge, I agree as follows:
(a)During the term of my employment and for a period of one (1) year after my employment with the Company is terminated for any reason whatsoever, I will not directly or indirectly, individually or on behalf of any other person, firm, partnership, corporation, or business entity of any type: (i) hire, solicit, assist, aid, induce, or in any way encourage any then-current employee or consultant of the Company or any affiliate or subsidiary of the Company to terminate his or her employment relationship or consulting relationship with the Company or subsidiary or affiliate; (ii) hire or solicit the services of any former employee or consultant of the Company or any affiliate or subsidiary of the Company whose employment has been terminated for less than six (6) months prior to such hire or solicitation; and/or (iii) induce or attempt to induce any other then-current employee of Company to work for, render services or provide advice to or supply Proprietary Information belonging to Company to any person or entity other than Company.
(b) During the term of my employment, and for a period of one (1) year after my employment with the Company is terminated for any reason whatsoever, I will not, directly or indirectly, for my own benefit or the benefit of any other person or entity, compete with the business of the Company or its successors or assigns in (i) each city, county, state, territory and country in which I provided services or had a material presence or influence at any time during the last two years of my employment or engagement with the Company and (ii) without limiting Section 7(b)(i), Massachusetts, North Carolina, Texas or in any other state in the United States (including, without limitation, all parishes and municipalities of Louisiana set forth on Exhibit B to this Agreement), or in any country in the world where the Company conducts material business or where the Company has taken active steps to commence conducting business; provided that I shall be permitted to acquire a passive stock or equity interest in such an entity provided the stock or other equity interest acquired is not more than one percent (1%) of the outstanding interests in such entity. The term “not compete” as used herein means that I will not directly or indirectly, as an owner, manager, officer,
5




director, employee, consultant, or stockholder, own, operate, manage, or engage in, or prepare to do any of the foregoing activities with respect to, a business substantially similar to or competitive with the business of the Company or such other business activity in which the Company may substantially engage during the term of my . Notwithstanding anything to the contrary in this Agreement, nothing set forth herein restricts your right to practice law after the end of the term of your employment to the extent such restriction would violate Texas Rule of Professional Conduct.

(c)During the term of my employment, and for a period of one (1) year after my employment with the Company is terminated for any reason, I will not, directly or indirectly, individually or on behalf of any other person, firm, partnership, corporation, or business entity of any type: (i) solicit, contact, call upon, communicate with, or attempt to communicate with, any Customer of the Company in order to provide or offer to provide any products or services that are similar to or otherwise competitive with any products or services provided or that could be provided by the Company; (ii) assist, induce or encourage, or attempt to assist, induce, or encourage any Customer of the Company to reduce or cease doing business with the Company; and/or (iii) influence a Customer to divert its business to any competitor of the Company or otherwise damage or negatively interfere or attempt to damage or negatively interfere with the Company’s relationship with a Customer in any way. For purposes of this Section 7(c), “Customer” shall mean any company or business entity that the Company had contact with or performed services for during the last twelve (12) months of my employment with the Company.
(d)I agree that following the termination of my employment with the Company, I will not access the Company’s computer systems, download files or any information from the Company’s computer systems or in any way interfere, disrupt, modify or change any computer program used by the Company or any data stored on the Company’s computer systems.
(e)I agree that if I should later claim any portion of Section 7 is unclear, unenforceable, overbroad or inapplicable to any activity in which I intend to engage, I must notify the Company, in writing, of my position at least fourteen (14) calendar days before engaging in such activity. During the 14-day period, I must meet face-to-face with the Company’s authorized representative, in good faith, to discuss resolution of the issue. A mediator may be hired, at the Company’s expense, to facilitate the discussion. If I fail or refuse to comply with this conflict resolution provision, I waive my right to challenge the scope, clarity, applicability, breadth or enforceability of Section 7 and all of its restrictions. However, all of my rights will be reserved if I comply with this provision even if no agreement is reached during the conference. Notwithstanding the foregoing provisions of this Section 7, nothing herein shall prevent the Company from seeking and obtaining immediate injunctive relief under Section 10, with or without prior notice to me, from any court of competent jurisdiction, prior to conducting the face-to-face meeting provided for herein.
(f)I agree that during and following the term of my employment with the Company, I will not make any private or public statements or comments about the Company and/or its products, services, practices, directors, officers, agents, representatives, or equity holders in any form, oral, written or electronic, which could constitute libel, slander, or disparagement or which may be considered to be derogatory or detrimental to the name or business reputation of the Company and/or its products, services, practices, directors, officers, agents, representatives, or equity holders; provided, however, that the terms of this subparagraph shall not apply to truthful statements required of me by law and/or communications between me and my spouse, clergy, or attorneys, which are subject to a claim of privilege existing under common law, statute, or rule of procedure.
8.Third-Party Agreements and Rights. I represent that I am not bound by the terms of any agreement with any previous employer or other party which restricts in any way my use or disclosure of confidential and proprietary information belonging to a previous employer or another party or which will restrict in any way my performance of any job duties, except as I have disclosed in Exhibit C to this Agreement prior to its acceptance by the Company; provided that, if no Exhibit C is attached, I represent that there are no such third party agreements. I have delivered to the Company true and complete copies of any agreements listed on Exhibit C, if any. I represent to the Company that my execution of this Agreement, my employment with the Company and the performance of my duties for the Company will not violate any obligations I may have to any previous employer or other party. In my work for the Company, I will not
6




disclose or make use of any information in violation of any agreements with or rights of any previous employer or other party, and I will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging to or obtained from any such previous employment or other party.
9.Return of Company Documents and Equipment. I agree that when my employment is terminated for any reason or earlier upon the Company’s request, I will immediately return all Company owned equipment and documents (paper and electronic) to the Company including, but not limited to, drawings, notes, memoranda, specifications, devices, and formulas, together with all copies thereof, and any other material containing or disclosing any Company Intellectual Property, including without limitation any inventions, Third Party Information, or Proprietary Information of the Company. I further agree that any property, including computers and communication systems, situated on the Company’s premises or which I am given or have access to in furtherance of my employment, including disks and other storage media, filing cabinets or other work areas, email communications, and Internet access is subject to inspection by Company personnel at any time for any reason with or without notice.
10.Legal and Equitable Remedies. Because my services are personal and unique and because I may have access to and become acquainted with the Proprietary Information of the Company and because any breach of the covenants under Section 7 would likely result in irreparable damage to the Company for which remedies at law would likely be inadequate, the Company shall have the right to enforce this Agreement and any of its provisions by injunction, specific performance, or other equitable relief, without bond (or other security) and without prejudice to any other rights and remedies that the Company may have for a breach of this Agreement.
11.Authorization to Notify New Employer. I hereby authorize the Company to notify my new employer about my rights and obligations under this Agreement following the termination of my employment with the Company for any reason whatsoever.
12.Notices. Any notices required or permitted hereunder shall be given to the appropriate party at the address specified below. Such notice shall be deemed given upon personal delivery to the appropriate address or if sent by certified or registered mail, three days after the date of mailing.
If to the Undersigned:
Most recent address on Company’s records.
If to the Company:
Ribbon Legal Department
3605 E. Plano Parkway
Plano, Texas 75074
13.General Provisions.
(a)Governing Law. This Agreement will be governed by and construed according to the laws of the state where I carry out my principal duties for the Company without regard to conflicts of law principles of any jurisdiction.
(b)Interpretation/Advice of Counsel. All terms and provisions of this Agreement, and the drafting of this Agreement, have been negotiated by the Parties at arm’s length and to mutual agreement, with consideration by and participation of each, and no party shall be deemed the scrivener of this Agreement. I acknowledge to the Company that I have been represented by licensed, independent legal counsel in connection with the drafting, negotiation and execution of this Agreement or have had a reasonable opportunity to engage such counsel and voluntarily elected to forgo representation thereby. I further acknowledge and agree that I fully understand all of the terms and provisions of this Agreement, am fully aware of their legal effect, intend that they shall be enforceable against me in accordance with their
7




terms, and have entered into this Agreement freely based on my own judgment and, to the extent applicable, the advice of my counsel.
(c)Arbitration. The provisions set forth in Section 8(g) of the employment letter to which this Agreement is attached are hereby incorporated by reference in this Agreement and shall apply hereto mutatis mutandis.
(d)Entire Agreement. This Agreement sets forth the entire agreement and understanding between the Company and myself relating to the subject matter hereof and supersedes and merges all prior discussions between us with respect to the subject matter hereof. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing signed by the party to be charged. Any subsequent change or changes in my duties, salary, or compensation will not affect the validity or scope of this Agreement. As used in this Agreement, the period of my employment includes any time during which I may be retained by the Company as a consultant or contractor. By executing this Agreement, I also acknowledge that: (i) I am not relying upon any statements, understandings, representations, expectations, or agreements other than those expressly set forth in this Agreement; and (ii) I knowingly waive any claim that this Agreement was induced by any misrepresentation or nondisclosure and any right to rescind or avoid this Agreement based upon presently existing facts, known or unknown. The Parties stipulate that each Party is relying upon these representations and warranties in entering into this Agreement. These representations and warranties shall survive the execution of this Agreement.
(e)Severability.
1.I acknowledge and agree that each agreement and covenant set forth herein constitutes a separate agreement independently supported by good and adequate consideration and that each such agreement shall be severable from the other provisions of this Agreement and shall survive this Agreement.
2.I understand and agree that Sections 1, 4 and 7 of this Agreement are each to be enforced to the fullest extent permitted by law. Accordingly, if a court of competent jurisdiction determines that the scope and/or operation of Section 1, 4 or 7 is too broad to be enforced as written, the Company and I intend that the court should reform such provision to such narrower scope and/or operation as it determines to be enforceable; provided, however, that such reformation applies only with respect to the operation of such provision in the particular jurisdiction with respect to which such determination was made. If, however, Section 1, 4 or 7 is held to be illegal, invalid, or unenforceable under present or future law, and not subject to reformation, then (i) such provision shall be fully severable, (ii) this Agreement shall be construed and enforced as if such provision was never a part of this Agreement, and (iii) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance. In the event a court determines that I have violated one of the post-employment, time-limited restrictions contained in Section 1, 4 or 7, then the time-limitation for the violated restriction shall be extended by one day for each day I am found to be in violation up to a maximum of one year.
(f)Successors and Assigns. This Agreement will be binding upon my heirs, executors, administrators, and other legal representatives and will be for the benefit of the Company, its successors and assigns. I may not assign this Agreement or my obligations hereunder without the prior written consent of the Company, which consent may be withheld in the Company’s sole discretion, and any such purported assignment without consent shall be null and void. I agree that the Company may freely assign or otherwise transfer this Agreement, including without limitation to any successor in interest of the Company, whether by way of merger, sale, acquisition or corporate re-organization or any substantially similar process.
(g)Survival. The provisions of this Agreement shall survive the termination of my employment and the assignment of this Agreement by the Company to any successor in interest or other assignee.
8




(h)Employment. I agree and understand that the nature of my employment, i.e., whether it is “at-will” or for a “term” is not defined by this Agreement but is determined by separate agreement between myself and the Company, if any. Nothing contained herein is intended to modify the nature of my employment relationship with the Company from being either “at-will” or for a “term,” whichever my employment relationship may be.
(i)Waiver. No waiver by the Company of any breach of this Agreement shall be a waiver of any preceding or succeeding breach. No waiver by the Company of any right under this Agreement shall be construed as a waiver of any other right. The Company shall not be required to give notice to enforce strict adherence to all terms of this Agreement.
(j)Headings. The headings to each section or paragraph of this Agreement are provided for
convenience of reference only and shall have no legal effect in the interpretation of the terms hereof.

3

b.The Company shall pay you an amount equal to the aggregate sum of the Company’s share of medical, dental and vision insurance premiums for you and your dependents for the period commencing on the Date of Termination and ending on the first anniversary thereof (as if you had remained employed and based on coverage as of immediately prior to termination).

The cash payment provided for in this Section 3(b)(i)(2) or Section 3(b)(ii)(2), as applicable, is referred to herein as the “Continued Benefit Payment”;
c.Unless otherwise explicitly set forth in the award agreement for the applicable Equity Award, each outstanding unvested Equity Award held by you immediately prior to the Date of Termination that is subject to vesting based solely upon your continuous service with the Company (collectively, “Time-Based Equity Awards”) that would have vested during the twelve (12)-month period following the Date of Termination had you remained employed shall remain outstanding and on the Severance Commencement Date, (I) to the extent you have timely executed and not revoked the Release Agreement (as defined below), such Time-Based Equity Awards shall automatically vest and become exercisable (as applicable) or (II) to the extent you have not timely executed or have revoked the Release Agreement, such Time-Based Equity Awards will be forfeited for no consideration; and
d.Unless otherwise explicitly set forth in the award agreement for the applicable Equity Award, each outstanding unvested Equity Award held by you immediately prior to the Date of Termination that is subject to vesting in whole or in part based on achievement of performance objective(s) (collectively, “Performance-Based Equity Awards”) and is eligible to vest based on achievement of such performance objective(s) for performance periods ending prior to the Date of Termination or in which the Date of Termination occurs shall remain outstanding and on the Severance Commencement Date, (I) to the extent you have timely executed and not revoked the Release Agreement, (x) the portion of such unvested Performance-Based Equity Award that is eligible to vest based on achievement of performance objective(s) for performance periods ending prior to the Date of Termination shall remain eligible to vest and be settled (as applicable) in accordance with its terms based on actual performance, without regard for any requirement of continued employment, and (y) a prorated amount of the
4




portion of such unvested Performance-Based Equity Award that is eligible to vest based on achievement of performance objective(s) for the applicable performance periods in which the Date of Termination occurs shall remain eligible to vest through the end of the fiscal year in which the Date of Termination occurs and be settled (as applicable) in accordance with its terms as if the last day of such fiscal year was the last day of the applicable performance period(s), based on performance targets established by the Company and actual performance through the end of such fiscal year, without regard for any requirement of continued employment, or (II) to the extent you have not timely executed or have revoked the Release Agreement, such Performance-Based Equity Awards will be forfeited for no consideration. The Company shall prorate the portion of each unvested Performance-Based Equity Award described in subsection (y) above based on the number of days of your employment during the performance period as compared to the total number of days in such performance period, with such prorated portion of such Performance-Based Equity Awards eligible to vest and become exercisable at the end of the fiscal year in which the Date of Termination occurs, based on the actual level of achievement of such performance objective(s) as of end of the applicable fiscal year (with the applicable performance objective(s) prorated for any shortened performance period). Any such determination by the Company shall be final and binding on all persons (including, without limitation, you). Notwithstanding anything to the contrary herein, settlement upon vesting (if any) of such Performance-Based Equity Awards described in subsection (ii) shall occur no later than March 15 of the calendar year immediately following the calendar year of the Date of Termination (or otherwise in compliance with Section 409A as required by their terms). For the avoidance of doubt, any Performance-Based Equity Award with respect to which performance vesting conditions have been determined to be fully satisfied prior to or as of the Date of Termination (or, which, in connection with a Change in Control or otherwise, was converted into an Equity Award solely subject to time-based vesting) shall be deemed to be a Time-Based Equity Award for purposes of this Agreement.
e.Subject to the provisions of Sections 3(c) and 7, (I) the Non-CIC Severance Payment shall be paid in equal installments during the twelve (12)-month period following the Date of Termination in accordance with the Company’s normal payroll practices beginning on the first payroll date following the 60th day following the Date of Termination (such payroll date, the “Severance Commencement Date”), and with the first installment including any amounts that would have been paid had the Release Agreement been effective and irrevocable on the Date of Termination, (II) the Pro Rata Bonus shall be paid at the same time as annual bonus payments are made to similarly situated employees of the Company for the applicable year, but in no event shall be paid earlier than January 1 or later than December 31 of the calendar year following the year of termination, and (III) the Continued Benefit Payment shall be paid in lump sum on the Severance Commencement Date, in each case, less applicable federal, state and other applicable withholdings.

For the avoidance of doubt, if immediately prior to the termination of your employment you were required to contribute towards the cost of premiums as a condition of receiving such insurance, the payment hereunder will not cover any such contributions; and
c.Unless otherwise explicitly set forth in the award agreement for the applicable Equity Award, any unvested Equity Awards outstanding immediately prior to the Date of Termination shall automatically become fully vested and exercisable (as applicable) as of the Date of Termination; provided that any Performance-Based Equity Award shall vest assuming a target level of achievement for each applicable performance objective(s).

d.Subject to the provisions of Sections 3(c) and 7, (I) the CIC Severance Payment shall be made in a lump sum on the Severance Commencement Date, (II) the Pro Rata Bonus shall be paid at the same time as annual bonus payments are made to similarly situated employees of the Company for the applicable year, but in no event shall be paid earlier than January 1 or later than December 31 of the calendar year following the year of termination, and (III) the Continued Benefit Payment shall be paid in lump sum on the Severance Commencement Date, in each case, less applicable federal, state and other applicable withholdings.

Notwithstanding anything to the contrary herein, the Company’s provision of the Severance Benefits will be contingent upon your timely execution and non-revocation of a general waiver and release of claims agreement in a form to be provided by the Company (a “Release Agreement”), subject to the terms set forth herein.

If the Release Agreement is signed and delivered by you to the Company, you will have seven (7) days from the date of delivery to revoke your acceptance of such agreement (the “Revocation Period”). If you do not timely execute or if you subsequently revoke the Release Agreement, you shall be required to pay to the Company, immediately upon demand therefor, the amount of any payments or benefits you received in connection with any portion of Equity Awards that was eligible to vest pursuant to Section 3(b) (including, without limitation, proceeds received or
6




realized by you from the sale or surrender of any shares underlying such Equity Awards in connection with applicable tax withholding).
iii.The provisions of this Section 3 shall supersede in their entirety any severance payment provisions in any severance plan, severance policy, severance program or other severance arrangement maintained by the Company or any of its affiliates (or any of their respective predecessors). The Company shall have no further obligation to you in the event of termination of your employment for any reason at any time, other than those obligations specifically set forth in this Section 3.
4.Resignation from Board, Officer and Other Positions. Unless otherwise determined by the Board, in the event that your employment is terminated for any reason (whether during or after the Term), you shall be deemed, effective as of the date of such termination, to resign (a) if a director, from the Board or similar board of directors of any direct or indirect parent, subsidiary or affiliate of the Company and (b) from any position with the Company or any direct or indirect parent, subsidiary or affiliate of the Company, including as an officer of the Company or any of its direct or indirect parents, subsidiaries or affiliates.
5.Mitigation.

6.Restrictive Covenants and Other Conditions. You acknowledge and agree that you are a party to that certain Confidentiality, Non-Competition and Assignment of Inventions Agreement, dated as of May 26, 2020, and such agreement remains in full force and effect (the “Restrictive Covenant Agreement”). In the event of (a) your material breach of the Restrictive Covenant Agreement, (b) your engagement in any act or omission after the Date of Termination that would have constituted “Cause” under subsections (ii) through (iv), (xii) or (xiii) of the definition thereof (without regard for any cure periods therein) for termination of your employment had you remained employed after the Date of Termination, or (c) the Company’s determination in good faith that facts or circumstances existed on the Date of Termination that, if known by the Company on the Date of Termination, would have constituted Cause, the Company shall be entitled to cease all payments and benefits pursuant to Section 3(b), all Equity Awards that vested pursuant to Section 3(b) and any shares of Company stock you received with respect thereto shall immediately be forfeited, without payment therefor, and you shall be required to pay to the Company, immediately upon demand therefor, the amount of any proceeds realized by you from the sale of any such shares.
7.Section 409A Tax Implications. Any payments or benefits required to be provided under this Agreement that is subject to Section 409A of the Code shall be provided only after the date of your “separation from service” with the Company as defined under Section 409A of the Code and the regulations and guidance issued thereunder (collectively, “Section 409A”). The following rules shall apply with respect to distribution of the payments and benefits, if any, to be provided to you under this Agreement:
7




(a)    To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A. Each installment of the payments and benefits provided hereunder shall be treated as a separate “payment” for purposes of Section 409A. If and to the extent (i) any portion of any payment, compensation or other benefit provided to you pursuant to this Agreement in connection with your termination of employment constitutes “nonqualified deferred compensation” within the meaning of Section 409A and (ii) you are a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, in each case as determined by the Company in accordance with its procedures, by which determinations you agree that you are bound, such portion of the payment, compensation or other benefit shall not be paid until the first business day that is six (6) months plus one (1) day or more after the date of “separation from service” (as determined under Section 409A) (the “New Payment Date”), except such earlier date as Section 409A may then permit. The aggregate of any payments that otherwise would have been paid to you during the period between the date of separation from service and the New Payment Date shall be paid to you in a lump sum on such New Payment Date, and any remaining payments will be paid on their original schedule.
1.The Company and its employees, agents and representatives make no representations or warranty and shall have no liability to you or any other person if any provisions of or payments, compensation or other benefits under this Agreement are determined to constitute nonqualified deferred compensation subject to Section 409A but do not satisfy the conditions of that section. Notwithstanding any provision of this Agreement to the contrary, in the event that following the Effective Date the Board determines that this Agreement may be subject to Section 409A, the Board may (but is not obligated to), without your consent, adopt such amendments to this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Board determines are necessary or appropriate to (i) exempt this Agreement from Section 409A and/or preserve the intended tax treatment of the benefits provided with respect to this Agreement or (ii) comply with the requirements of Section 409A and thereby avoid the application of any penalty taxes under Section 409A.
8.Section 280G. If any payment or benefit you would receive or retain under this Agreement, when combined with any other payment or benefit you receive or retain in connection with a “change in control event” within the meaning of Section 280G of the Code and the regulations and guidance thereunder (“Section 280G”), would (a) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (b) but for this Section 8, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be either payable in full or in such lesser amount as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employment taxes, income taxes, and the Excise Tax, results in your receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. All determinations required to be made under this Section 8, including whether and to what extent the Payment shall be reduced and the assumptions to be utilized in arriving at such determination, shall be made by a nationally recognized certified public accounting firm or consulting firm experience in matters regarding Section 280G of the Code as may be designated by the Company (the “280G Advisor”). The 280G Advisor shall provide detailed supporting calculations both to you and the Company at such time as is requested by the Company. All fees and expenses of the 280G Advisor shall be borne solely by the Company. Any final determination by the 280G Advisor shall be binding upon you and the Company. For purposes of making the calculations required by this Section 8, the 280G Advisor may make reasonable assumptions and
8




approximations concerning applicable taxes and may rely on reasonable, good-faith interpretations concerning the application of Sections 280G and 4999 of the Code.
9.Withholding. The Company shall be entitled to withhold from any amounts payable under this Agreement any federal, state, local or foreign withholding or other taxes or charges that the Company is required to withhold. The Company shall be entitled to rely on an opinion or advice of counsel if any questions as to the amount or requirement of withholding arise.
10.Miscellaneous.

(a)This Agreement, together with any written employment agreement or offer letter to which you may be a party and any agreements referenced herein, will constitute our entire agreement as to your employment by the Company and will supersede any prior agreements or understandings, whether in writing or oral, with respect to the subject matter hereof, other than with respect to any agreements between you and the Company with respect to confidential information, intellectual property, non-competition, non-solicitation, non-disparagement, nondisclosure of proprietary information, inventions and injunctive relief, including, without limitation, the Restrictive Covenant Agreement; provided that Section 10(f) supersedes and replaces any prior dispute resolution provisions in any other prior agreement between you and the Company (including, without limitation, the Restrictive Covenant Agreement).

(b)This Agreement may be executed in more than one counterpart, each of which shall be deemed to be an original, and all such counterparts together shall constitute one and the same instrument.

(c)The provisions of this Agreement are severable and if any one or more provisions may be determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions of this Agreement shall nevertheless be binding and enforceable and except to the extent necessary to reform or delete such illegal or unenforceable provision, this Agreement shall remain unmodified and in full force and effect.

(d)This Agreement is personal in nature and neither of the parties hereto shall, without the written consent of the other, assign or otherwise transfer this Agreement or its obligations, duties and rights under this Agreement; provided, however, that in the event of the merger, consolidation, transfer or sale of all or substantially all of the assets of the Company, the Company may assign its rights and obligations hereunder and, in the event of such assignment, this Agreement shall, subject to the provisions hereof, be binding upon and inure to the benefit of such successor and such successor shall be solely obligated to discharge and perform all of the promises, covenants, duties and obligations of the Company hereunder.

(e)All notices shall be in writing and shall be delivered personally (including by courier), by overnight receipted courier service (such as UPS or Federal Express) or sent by certified, registered or express mail, postage prepaid, to the Company at the following address: Ribbon Communications Legal Department, 3605 E. Plano Parkway, Plano, Texas 75074, Attn: Head of Legal, and to you at the most current address we have in your employment file. Any such notice shall be deemed given when so delivered personally or, if by certified, registered or express mail, postage prepaid mailed, forty-eight (48)
9




hours after the date of deposit in the mail. Any party may, by notice given in accordance with this paragraph to the other party, designate another address or person for receipt of notices hereunder.

(f)The provisions set forth in Section 8(g) of the Employment Letter are hereby incorporated by reference in this Agreement and shall apply hereto mutatis mutandis.

By signing this offer letter, you agree that any amounts owed pursuant to this Section C may be withheld from your final paycheck and/or outstanding business expense reimbursements;
ii.Enter into an at-will employment agreement (including a confidentiality, non-competition, non-Solicitation and assignment of inventions agreement and

b.The Company shall pay you an amount equal to the aggregate sum of the Company's share of medical, dental and vision insurance premiums for you and your dependents for the period commencing on the Date of Termination and ending on the first anniversary thereof (as if you had remained employed and based on coverage as of immediately prior to termination); provided that, to the extent the Company is required to provide you with continued benefits for any period after termination under the ESA, then it shall, in lieu of payments under this Section 3(b)(i)(2) in respect of such period, provide you coverage under such insurance for such period. For the avoidance of doubt, if immediately prior to the termination of your employment you were required to contribute towards the cost of premiums as a condition of receiving such insurance, the payment (or coverage) hereunder will not cover any such contributions. The cash payment or coverage provided for in this Section 3(b)(i)(2) or Section 3(b)(ii)(2), as applicable, is referred to herein as the “Continued Benefit Payment”;
c.Unless otherwise explicitly set forth in the award agreement for the applicable Equity Award, each outstanding unvested Equity Award held by you immediately prior to the Date of Termination that is subject to vesting based solely upon your continuous service with the Company (collectively, “Time-Based Equity Awards”) that would have vested during the twelve (12)-month period following the Date of Termination had you remained employed shall remain outstanding and on the Severance Commencement Date, (I) to the extent you have timely executed the Release Agreement, such Time-Based Equity Awards shall automatically vest and become exercisable (as applicable) or (II) to the extent you have not timely executed the Release Agreement, subject to the minimum requirements of the ESA such Time-Based Equity Awards will be forfeited for no consideration and you waive any claims to damages (whether at common law or otherwise) in respect thereof; and
d.Unless otherwise explicitly set forth in the award agreement for the applicable Equity Award, each outstanding unvested Equity Award held by you immediately prior to the Date of Termination that is subject to vesting in whole or in part based on achievement of performance objective(s) (collectively, “Performance-Based Equity Awards”) and is eligible to vest based on achievement of such performance objective(s) for performance periods ending prior to the Date of Termination or in which the Date of Termination occurs shall remain outstanding and on the Severance Commencement Date, (I) to the extent you have timely executed the Release Agreement, (x) the portion of such unvested Performance-Based Equity Award that is eligible to vest based on achievement of performance objective(s) for performance periods ending prior



to the Date of Termination shall remain eligible to vest and be settled (as applicable) in accordance with its terms based on actual performance, without regard for any requirement of continued employment, and (y) a prorated amount of the portion of such unvested Performance-Based Equity Award that is eligible to vest based on achievement of performance objective(s) for the applicable performance periods in which the Date of Termination occurs shall remain eligible to vest through the end of the fiscal year in which the Date of Termination occurs and be settled (as applicable) in accordance with its terms as if the last day of such fiscal year was the last day of the applicable performance period(s), based on performance targets established by the Company and actual performance through the end of such fiscal year, without regard for any requirement of continued employment, or (II) to the extent you have not timely executed the Release Agreement, subject to the minimum requirements of the ESA such Performance-Based Equity Awards will be forfeited for no consideration and you waive any claim to damages (whether at common law or otherwise) in respect thereof. The Company shall prorate the portion of each unvested Performance-Based Equity Award described in subsection (y) above based on the number of days of your employment during the performance period as compared to the total number of days in such performance period, with such prorated portion of such Performance-Based Equity Awards eligible to vest and become exercisable at the end of the fiscal year in which the Date of Termination occurs, based on the actual level of achievement of such performance objective(s) as of end of the applicable fiscal year (with the applicable performance objective(s) prorated for any shortened performance period). Any such determination by the Company shall be final and binding on all persons (including, without limitation, you). Notwithstanding anything to the contrary herein, settlement upon vesting (if any) of such Performance-Based Equity Awards described in subsection (ii) shall occur no later than March 15 of the calendar year immediately following the calendar year of the Date of Termination (or otherwise in compliance with applicable law). For the avoidance of doubt, any Performance-Based Equity Award with respect to which performance vesting conditions have been determined to be fully satisfied prior to or as of the Date of Termination (or, which, in connection with a Change in Control or otherwise, was converted into an Equity Award solely subject to time-based vesting) shall be deemed to be a Time-Based Equity Award for purposes of this Severance Agreement.
e.Subject to the provisions of Section 3(c), (I) the Non-CIC Severance Payment shall be paid in equal installments during the twelve (12)-month period following the Date of Termination in accordance with the Company’s normal payroll practices beginning on the first payroll date following the 60th day following the Date of Termination (such payroll date, the “Severance Commencement Date”), and with the first installment including any amounts that would have been paid had the Release Agreement been effective and irrevocable on the Date of Termination, (II) the Pro Rata Bonus, if any, shall be paid at the same time as annual bonus payments are made to similarly situated employees of the Company for the applicable year, but in no event shall be paid earlier than January 1 or later than December 31 of the calendar year following the year of termination, and (III) the Continued Benefit Payment, to the extent payable in cash, shall be paid in lump sum on the Severance Commencement Date (or, if later, the first payroll date following the end of any period in which insurance coverage is required under the ESA), in each case, less applicable federal, provincial and other applicable withholdings.



a.If the Company terminates your employment without Cause or if you terminate your employment with Good Reason, in each case, during the Change in Control Protection Period, then, in addition to the Accrued Benefits, the Company will provide you the following severance and related post-termination benefits:
a.The Company shall pay to you a cash lump sum payment in an amount equal to (A) the sum of twelve (12) months of your Base Pay as in effect immediately prior to the Date of Termination and your target Annual Bonus for the calendar year in which the Date of Termination occurs (or in the case of termination by you with Good Reason due to material reduction in Base Pay and/or target Annual Bonus, your Base Pay and/or target Annual Bonus in effect immediately prior to such reduction, as applicable) (the “CIC Severance Payment”), and (B) the Pro Rata Bonus;
b.The Company shall pay you an amount equal to the aggregate sum of the Company's share of medical, dental and vision insurance premiums for you and your dependents for the period commencing on the Date of Termination and ending on the first anniversary thereof (as if you had remained employed and based on coverage as of immediately prior to termination); provided that, to the extent the Company is required to provide you with continued benefits for any period after termination under the ESA, then it shall, in lieu of payments under this Section 3(b)(ii)(2) in respect of such period, provide you coverage under such insurance for such period. For the avoidance of doubt, if immediately prior to the termination of your employment you were required to contribute towards the cost of premiums as a condition of receiving such insurance, the payment (or coverage) hereunder will not cover any such contributions; and
c.Unless otherwise explicitly set forth in the award agreement for the applicable Equity Award, any unvested Equity Awards outstanding immediately prior to the Date of Termination shall automatically become fully vested and exercisable (as applicable) as of the Date of Termination; provided that any Performance-Based Equity Award shall vest assuming a target level of achievement for each applicable performance objective(s).

d.Subject to the provisions of Section 3(c), (I) the CIC Severance Payment shall be made in a lump sum on the Severance Commencement Date, (II) the Pro Rata Bonus, if any, shall be paid at the same time as annual bonus payments are made to similarly situated employees of the Company for the applicable year, but in no event shall be paid earlier than January 1 or later than December 31 of the calendar year following the year of termination, and (III) the Continued Benefit Payment, to the extent payable in cash, shall be paid in lump sum on the Severance Commencement Date (or, if later, the first payroll date following the end of any period in which insurance coverage is required under the ESA), in each case, less applicable federal, state and other applicable withholdings.
iii.Release. Any amounts payable pursuant to Section 3(b)(i) or Section 3(b)(ii), as applicable (collectively, the “Severance Benefits”), shall be in satisfaction of all of the Company’s obligations to you in relation to the termination of your employment and you shall have no further entitlements in respect thereof from the Ribbon Entities, whether pursuant to common law or otherwise, except as may be expressly required by the ESA. Notwithstanding anything to the contrary herein, the Company's provision of the Severance Benefits (to the extent only that such



Severance Benefits exceed your minimum entitlements under to the ESA) will be contingent upon your timely execution of a general waiver and release of claims agreement in a form to be provided by the Company (a “Release Agreement”), subject to the terms set forth herein. You will have seven (7) days following your receipt of the Release Agreement to consider whether or not to accept it. If you do not timely execute the Release Agreement, you shall be required to pay to the Company, immediately upon demand therefor, the amount of any payments or benefits you received in connection with any portion of Equity Awards that was eligible to vest pursuant to Section 3(b) (including, without limitation, proceeds received or realized by you from the sale or surrender of any shares underlying such Equity Awards in connection with applicable tax withholding). For greater certainty, if you do not sign the Release Agreement, you will receive all of your minimum statutory entitlements under the ESA. However, no further amounts or benefits will be provided.
iv.The provisions of this Section 3 shall supersede in their entirety any severance payment provisions in any severance plan, severance policy, severance program or other severance arrangement maintained by the Company or any of its affiliates (or any of their respective predecessors). The Company shall have no further obligation to you in the event of termination of your employment for any reason at any time, other than those obligations specifically set forth in this Section 3 or as otherwise expressly required by the ESA.
4.Mitigation. You shall not be required to mitigate the amount of any payment or benefit provided for in Section 3 by seeking other employment or otherwise, nor shall the amount of any payment or benefit provided for in Section 3 be reduced by any compensation earned by you as the result of employment by another employer or by retirement benefits after the Date of Termination or otherwise, subject to Section 5; provided, however, that any loans, advances or other amounts owed by you to the Company may be offset by the Company and its affiliates against amounts payable to you under Section 3 to the greatest extent permitted by applicable law.
5.Restrictive Covenants and Other Conditions. You acknowledge and agree that you are a party to that certain Confidentiality, Non-Disclosure, and Non-Solicitation/Non-Competition and Other Restrictive Covenants Agreement, dated as August 31, 2020 and such agreement remains in full force and effect (the “Restrictive Covenant Agreement”). In the event of (a) your material breach of the Restrictive Covenant Agreement, (b) your engagement in any act or omission after the Date of Termination that would have constituted “Cause” under subsections (ii) through (iv), (xii) or (xiii) of the definition thereof (without regard for any cure periods therein) for termination of your employment had you remained employed after the Date of Termination, or (c) the Company’s determination in good faith that facts or circumstances existed on the Date of Termination that, if known by the Company on the Date of Termination, would have constituted Cause, the Company shall be entitled to cease all payments and benefits pursuant to Section 3(b), all Equity Awards that vested pursuant to Section 3(b) and any shares of Company stock you received with respect thereto shall immediately be forfeited, without payment therefor, and you shall be required to pay to the Company, immediately upon demand therefor, the amount of any proceeds realized by you from the sale of any such shares, subject to applicable law.
6.Withholding. The Company shall be entitled to withhold from any amounts payable under this Agreement any federal, provincial, local or foreign withholding or other taxes or charges that the Company is required to withhold. The Company shall be entitled to rely on an opinion or advice of counsel if any questions as to the amount or requirement of withholding arise.
7.Miscellaneous.




(a)This Agreement, together with any written employment agreement or offer letter to which you may be a party and any agreements referenced herein, will constitute our entire agreement as to your employment by the Company and will supersede any prior agreements or understandings, whether in writing or oral, with respect to the subject matter hereof, other than with respect to any agreements between you and the Company with respect to confidential information, intellectual property, non-competition, non-solicitation, non-disparagement, nondisclosure of proprietary information, inventions and injunctive relief, including, without limitation, the Restrictive Covenant Agreement; provided that Section 7(g) supersedes and replaces any prior dispute resolution provisions in any other prior agreement between you and the Company (including, without limitation, the Restrictive Covenant Agreement).

(b)This Agreement may be executed in more than one counterpart, each of which shall be deemed to be an original, and all such counterparts together shall constitute one and the same instrument.

(c)In the event that the minimum standards in the ESA are more favourable to you in respect of any clause or provision of this Agreement, the relevant minimum standard in the ESA shall apply in place of that clause of provision.

(d)The provisions of this Agreement are severable and if any one or more provisions may be determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions of this Agreement shall nevertheless be binding and enforceable and except to the extent necessary to reform or delete such illegal or unenforceable provision, this Agreement shall remain unmodified and in full force and effect.

(e)This Agreement is personal in nature and neither of the parties hereto shall, without the written consent of the other, assign or otherwise transfer this Agreement or its obligations, duties and rights under this Agreement; provided, however, that in the event of the merger, consolidation, transfer or sale of all or substantially all of the assets of the Company, this Agreement shall, subject to the provisions hereof, be binding upon and inure to the benefit of such successor and such successor shall discharge and perform all of the promises, covenants, duties and obligations of the Company hereunder.

(f)All notices shall be in writing and shall be delivered personally (including by courier), sent by facsimile transmission (with appropriate documented receipt thereof), by overnight receipted courier service (such as UPS or Federal Express) or sent by certified, registered or express mail, postage prepaid, to the Company at the following address: Ribbon Communications Legal Department, 3605 E. Plano Parkway, Plano, Texas 75074, Attn: Head of Legal, and to you at the most current address we have in your employment file. Any such notice shall be deemed given when so delivered personally, or if sent by facsimile transmission, when transmitted, or, if by certified, registered or express mail, postage prepaid mailed, forty-eight (48) hours after the date of deposit in the mail. Any party may, by notice given in accordance with this paragraph to the other party, designate another address or person for receipt of notices hereunder.

(g)Arbitration. Notwithstanding anything to the contrary (including, without limitation, any other written agreement by and between you and any Ribbon Entity):




1.Any controversy, dispute or claim arising out of or relating to this Agreement or the breach hereof (a “Dispute”) which cannot be settled by mutual agreement will be finally settled by binding arbitration in the Province of Ontario, before a single arbitrator.  The arbitrator may enter a default decision against any party who fails to participate in the arbitration proceedings, subject to applicable law.

2.The decision of the arbitrator on the points in dispute will be final, non-appealable and binding, and judgment on the award may be entered in any court having jurisdiction thereof.

3.The fees and expenses of the arbitrator will be shared equally by the parties, and each party will bear the fees and expenses of its own lawyer in connection with any Dispute; provided that, to the extent the arbitrator determines you have prevailed on at least one material issue involved in any Dispute commencing during the Change in Control Protection Period, the Company shall reimburse you for all reasonable legal fees in connection with such Dispute.

4.The parties agree that this Section 7(g) has been included to resolve any Disputes, and that this Section 7(g) will be grounds for dismissal of any court action commenced by either party with respect to this Agreement, other than post-arbitration actions seeking to enforce an arbitration award or actions seeking an injunction or temporary restraining order.  In the event that any court determines that this arbitration procedure is not binding, or otherwise allows any litigation regarding a Dispute to proceed, the parties hereto hereby waive, to the maximum extent allowed by law, any and all right to a trial by jury in or with respect to such litigation.

5.The parties will keep confidential, and will not disclose to any person, except as may be required by law or the rules and regulations of the U.S. Securities and Exchange Commission or other government agencies, the existence of any controversy hereunder, the referral of any such controversy to arbitration or the status or resolution thereof.

(h)This Agreement shall be governed by and interpreted in accordance with the laws of the Province of Ontario and the laws of Canada applicable therein, without regard to the conflict of laws provisions thereof or of any other jurisdiction.

8.Acceptance. You may accept the terms and conditions described herein by confirming your acceptance in writing. Please send your countersignature to this Agreement to the Company, or via e-mail to me, which execution will evidence your agreement with the terms and conditions set forth herein.
