Special Note Regarding Forward-Looking Statement
This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the Securities Act), and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). All statements contained in this Quarterly Report on Form 10-Q, other than statements of historical fact, are forward-looking statements. Forward-looking statements generally can be identified by the words “may,” “will,” “expect,” “believe,” “anticipate,” “intend,” “could,” “estimate,” or “continue,” and similar expressions. We have based these forward-looking statements largely on our current expectations and projections about future events, as well as trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These statements include, among other things:
our beliefs regarding delivery traffic growth trends and demand for digital content and edge services;
our expectations regarding revenue, costs, expenses, gross margin, non-GAAP earnings per share, Adjusted EBITDA and capital expenditures;
our plans regarding investing in our eXperience Delivery Network (XDN), as well as other products and technologies;
our beliefs regarding the competition within the digital edge platform industry;
our beliefs regarding the growth of our business and how that impacts our liquidity and capital resources requirements;
our expectations regarding headcount and our ability to recruit personnel;
the impact of certain new accounting standards and guidance as well as the time and cost of continued compliance with existing rules and standards;
our plans with respect to investments in marketable securities;
our expectations and strategies regarding acquisitions;
our expectations regarding litigation and other pending or potential disputes;
our estimations regarding taxes and belief regarding our tax reserves;
our beliefs regarding the use of Non-GAAP financial measures;
our approach to identifying, attracting and keeping new and existing clients, our focus on core market growth segments where we have a right-to-win, as well as our expectations regarding client turnover;
the sufficiency of our sources of funding;
the sufficiency of our facilities to meet our needs;
our beliefs regarding our interest rate risk;
our beliefs regarding inflation risks;
our beliefs regarding expense and productivity of and competition for our sales force;
our beliefs regarding the significance of our large clients; and
our beliefs regarding the impact of health epidemics and pandemics, including the outbreak of COVID-19, on our current and potential clients, and our balance sheet, financial condition, and results of operations.
    These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described under the caption “Risk Factors” in Part II, Item 1A in this Quarterly Report on Form 10-Q and those discussed in other documents we file with the Securities and Exchange Commission (SEC).
In addition, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.
The forward-looking statements contained herein are based on our current expectations and assumptions and on information available as of the date of the filing of this Quarterly Report on Form 10-Q. We undertake no obligation to revise or publicly release the results of any revision to these forward-looking statements, except as required by law. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements.
Unless expressly indicated or the context requires otherwise, the terms "Limelight," "we," "us," and "our" in this document refer to Limelight Networks, Inc., a Delaware corporation, and, where appropriate, its wholly owned subsidiaries. All information is presented in thousands, except per share amounts, client count, headcount and where specifically noted.

2. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities Exchange Commission (SEC). They do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Such interim financial information is unaudited but reflects all adjustments that are, in the opinion of management, necessary for the fair presentation of the interim periods presented and of a normal recurring nature. This quarterly report on Form 10-Q should be read in conjunction with our audited financial statements and footnotes included in our annual report on Form 10-K for the fiscal year ended December 31, 2020. All information is presented in thousands, except per share amounts and where specifically noted.
The consolidated financial statements include accounts of Limelight and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. In addition, certain other reclassifications have been made to prior year amounts to conform to the current year presentation.
Use of Estimates
The preparation of the consolidated financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments, assumptions, and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results and outcomes may differ from those estimates. The results of operations presented in this quarterly report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, or for any future periods.
Recent Accounting Standards
Adopted Accounting Standards            
In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12 to simplifying the accounting for income taxes. ASU 2019-12 is intended to simplify various aspects related to accounting for income taxes, eliminates certain exceptions to the general principles in the Accounting Standards Codification (ASC) Topic 740 related to intra-period tax allocation, simplifies when companies recognize deferred taxes in an interim period, and clarifies certain aspects of the current guidance to promote consistent application. We adopted this guidance effective January 1, 2021. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures.
In August 2020, the FASB issued ASU 2020-06, which simplifies the accounting for convertible instruments. ASU 2020-06 eliminates certain models that require separate accounting for embedded conversion features, in certain cases. Additionally, among other changes, the guidance eliminates certain of the conditions for equity classification for contracts in an entity’s own equity. ASU 2020-06 also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and include the effect of share settlement for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. We early adopted this guidance on January 1, 2021, on a modified retrospective basis. As a result of the adoption of ASU 2020-06, our total remaining interest expense over the contractual terms of our convertible debt will be approximately $20,823 less than under the previous accounting standards. The adoption resulted in a $21,733 decrease in additional paid in capital from the derecognition of the bifurcated equity component, $20,255 increase in debt from the derecognition of the discount associated with the bifurcated equity component and $1,677 decrease to the opening balance of accumulated deficit, representing the cumulative interest expense recognized related to the
10

Table of Contents
amortization of the bifurcated conversion option. We wrote-off the related deferred tax liabilities with a corresponding adjustment to the valuation allowance, resulting in no net tax impact to the cumulative adjustment to retained earnings.
Significant Accounting Policies
There have been no changes in the significant accounting policies from those that were disclosed in our Annual Report, except for restructuring charge and convertible senior notes as described below:
Restructuring Charges
We account for restructuring costs under ASC 420, Exit or Disposal Obligations. Restructuring costs are recognized when the liability is incurred. A restructuring liability related to employee terminations is recorded when a one-time benefit arrangement is communicated to an employee who is involuntarily terminated as part of a reorganization and the amount of the termination benefit is known, provided that the employee is not required to render future services in order to receive the termination benefit. If fixed assets, or other assets are to be disposed of as a result of our restructuring efforts, the assets are written off when we commit to dispose of them, and they are no longer in use. If applicable, depreciation is accelerated on fixed assets for the period of time the asset continues to be used until the asset ceases to be used. Other restructuring costs are generally recorded as the cost is incurred or the service is provided.
Convertible Senior Notes
In July 2020, we issued $125,000 aggregate principal amount of 3.50% convertible senior notes. Effective January 1, 2021, we early adopted ASU 2020-06. The conversion option that was previously accounted for under the cash conversion model or beneficial conversion feature model was recombined into a single instrument that is classified as a liability for convertible debt or equity for equity-classified preferred stock.
Revenue Recognition
Revenues are recognized when control of the promised goods or services is transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.
For contracts that contain minimum commitments over the contractual term, we estimate an amount of variable consideration by using the expected value method. We include estimates of variable consideration in revenue only when we have a high degree of confidence that revenue will not be reversed in a subsequent reporting period. We believe that the expected value method is the most appropriate estimate of the amount of variable consideration. These clients have entered into contracts with contract terms generally from one to four years. As of June 30, 2021, we have approximately $5,159 of remaining unsatisfied performance obligations. We recognized revenue of approximately $2,455 and $1,943, respectively, during the three months ended June 30, 2021 and 2020, related to these types of contracts with our clients. During the six months ended June 30, 2021 and 2020, we recognized approximately $4,356 and $4,097, respectively. We expect to recognize approximately 67% of the remaining unsatisfied performance obligations in 2021, approximately 31% in 2022, and approximately 2% in 2023.

Convertible Senior Notes - Due 2025
On July 27, 2020, we issued $125,000 aggregate principal amount of 3.50% Convertible Senior Notes due 2025 (the Notes), including the initial purchasers’ exercise in full of their option to purchase an additional $15,000 principal amount of the Notes, in a private placement to qualified institutional buyers in an offering exempt from registration under the Securities Act of 1933, as amended. The net proceeds from the issuance of the Notes was $120,741 after deducting transaction costs.
The Notes are governed by an indenture (the Indenture) between us, as the issuer, and U.S. Bank, National
13

Table of Contents
Association, as trustee. The Notes are senior, unsecured obligations of ours and will be equal in right of payment with our senior, unsecured indebtedness; senior in right of payment to our indebtedness that is expressly subordinated to the notes; effectively subordinated to our senior, secured indebtedness, including future borrowings, if any, under our $20,000 credit facility with Silicon Valley Bank (SVB), to the extent of the value of the collateral securing that indebtedness; and structurally subordinated to all indebtedness and other liabilities, including trade payables, and (to the extent we are not a holder thereof) preferred equity, if any, of our subsidiaries. The Indenture includes customary covenants and sets forth certain events of default after which the Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving us after which the Notes become automatically due and payable.
The Notes mature on August 1, 2025, unless earlier converted, redeemed or repurchased in accordance with their term prior to the maturity date. Interest is payable semiannually in arrears on February 1 and August 1 of each year, beginning on February 1, 2021. The holders of the Notes may convert all or any portion of their Notes at their option only in the following circumstances:
(1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2020 (and only during such calendar quarter), if the last reported sale price per share of our common stock exceeds 130% of the conversion price of $8.53 for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;
(2) during the five consecutive business days immediately after any ten consecutive trading day period (such ten consecutive trading day period, the measurement period) in which the trading price per $1 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of our common stock on such trading day and the conversion rate on such trading day;
(3) upon the occurrence of certain corporate events or distributions of our common stock;
(4) if we call such Notes for redemption; and
(5) at any time from, and including, May 1, 2025, until the close of business on the second scheduled trading day immediately before the maturity date.
On or after May 1, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes, in minimum principal amount denominations of $1 or any integral multiple of $1 in excess thereof, at the option of the holder regardless of the foregoing circumstances. Upon conversion, we may satisfy our conversion obligation by paying or delivering, as applicable, cash, shares of common stock or a combination of cash and shares of common stock, at our election, in the manner and subject to the terms and conditions provided in the Indenture. The Notes have an initial conversion rate of 117.2367 shares of our common stock per $1 principal amount of Notes, which is equal to an initial conversion price of approximately $8.53 per share of our common stock. The initial conversion price of the notes represents a premium of approximately 27.5% over the last reported sale price of our common stock on The Nasdaq Global Select Market of $6.69 per share on July 22, 2020. The conversion rate is subject to adjustment under certain circumstances in accordance with the terms of the Indenture. In addition, following certain corporate events that occur prior to the maturity date or if we deliver a notice of redemption, we will increase the conversion rate in certain circumstances for a holder who elects to convert its Notes in connection with such a corporate event or convert its Notes called (or deemed called) for redemption in connection with such notice of redemption, provided that the conversion rate will not exceed 149.4768 share of our common stock per $1 principal amount of Notes, subject to adjustment.
We may not redeem the Notes prior to August 4, 2023. We may redeem for cash all, or any portion in an authorized denomination, of the Notes, at our option, on or after August 4, 2023, and on or prior to the 41st scheduled trading day immediately preceding the maturity date, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days, whether or not consecutive, including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Notes, which means that we are not required to redeem or retire the Notes periodically.
If we undergo a fundamental change (as defined in the Indenture), holders may require us to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.
As of June 30, 2021, the conditions allowing holders of the Notes to convert had not been met and therefore the Notes are not yet convertible. The Notes are classified as long-term debt on our condensed consolidated balance sheet as of June 30,

2021, and the liability component of the notes are classified as long-term debt on our condensed consolidated balance sheet as of December 31, 2020.
At the time of issuance in July 2020, we separately accounted for the liability and equity components of the Notes. We determined the initial carrying amount of the $102,500 liability component before consideration of debt discount and transaction fees by calculating the present value of the cash flows using an effective interest rate of 8.6%. The interest rate was determined based on non-convertible debt offerings of similar sizes and terms by companies with similar credit ratings (Level 2 inputs). The carrying amount of the equity component, representing the conversion option, was $22,500 and was calculated by deducting the initial carrying value of the liability component from the principal amount of the Notes as a whole. This difference represents a debt discount that is amortized to interest expense over the 5-year contractual term of the Notes using the effective interest rate method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. On January 1, 2021, we early adopted ASU 2020-06 on a modified retrospective basis. As a result of the adoption of ASU 2020-06, our total remaining interest expense over the contractual terms of our convertible debt will be approximately $20,823 less than under the previous accounting standards. The adoption resulted in a $21,733 decrease in additional paid in capital from the derecognition of the bifurcated equity component, $20,255 increase in debt from the derecognition of the discount associated with the bifurcated equity component and $1,677 decrease to the opening balance of accumulated deficit, representing the cumulative interest expense recognized related to the amortization of the bifurcated conversion option.
We initially allocated transaction costs related to the issuance of the Notes to the liability and equity components using the same proportions as the initial carrying value of the Notes. Transaction costs initially attributable to the liability component were $3,400 and are being amortized to interest expense using the effective interest method over the term of the Notes. Transaction costs attributable to the equity component were $859. Following the adoption of ASU 2020-06, the transaction costs attributable to the original equity component are now being amortized to interest expense over the remaining term of the Notes.
The net carrying amount of the liability and equity components of the Notes was as follows:

As of June 30, 2021, and December 31, 2020, the estimated fair value of the Notes was $113,804 and $114,233, respectively. We estimated the fair value based on the quoted market prices in an inactive market on the last trading day of the reporting period, which are considered Level 2 inputs.
Capped Call Transactions
In connection with the offering of the Notes, we entered into privately negotiated capped call transactions with certain counterparties (collectively, the Capped Calls). The Capped Calls have an initial strike price of approximately $8.53 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Notes. The Capped Calls have an initial cap price of $13.38 per share, subject to certain adjustments. The Capped Calls are generally intended to reduce or offset the
