PRELIMINARY PROXY STATEMENT DATED APRIL 22, 2022—SUBJECT TO COMPLETION

PROPOSED TRANSACTION—YOUR VOTE IS VERY IMPORTANT

Dear Stockholders,

You are cordially invited to attend the 2022 annual meeting of stockholders of Limelight Networks, Inc., a Delaware corporation (“Limelight”), which will be held virtually on [●], [●], 2022 at [●] Eastern time (including any adjournments or postponements thereof, the “annual meeting”). Stockholders will be able to attend the annual meeting by visiting www.virtualshareholdermeeting.com/LLNW2022 and using the 16-digit control number included in your proxy materials. You will not be able to attend the annual meeting physically in person. For purposes of attendance at the annual meeting, all references in the accompanying proxy statement to “present in person” or “in person” shall mean virtually present at the annual meeting.

At the annual meeting, you will be asked to consider and vote, among other things, upon the approval of the issuance of shares of common stock, par value $0.001 per share, of Limelight (“Limelight common stock”) pursuant to the Stock Purchase Agreement, dated as of March 6, 2022 (the “purchase agreement”), providing for the purchase of all of the outstanding shares of common stock of Edgecast Inc. (“Edgecast”), a California corporation and an indirect wholly-owned subsidiary of College Parent, L.P. (together with its wholly-owned subsidiaries other than Edgecast, “College Parent”), and certain assets specified in the purchase agreement. After the completion of the transaction, right, title and interest in and to all of the outstanding shares of common stock of Edgecast and certain subsidiaries of Edgecast will be owned by an indirect, wholly-owned subsidiary of Limelight.

If the transactions contemplated by the purchase agreement (the “transaction”) are completed, Limelight currently anticipates issuing approximately 71.9 million shares of Limelight common stock to either College Parent, the ultimate parent company of Edgecast, or a designated subsidiary of College Parent, representing a value of approximately $300 million at a share price of $4.1168 (which is the 30-day trailing VWAP as of March 4, 2022), which includes approximately $30 million cash investment in Limelight by College Parent or a designated subsidiary. College Parent or a designated subsidiary can also receive up to an additional 12.7 million shares of Limelight representing up to an additional $100 million in consideration, over the period ending on the third anniversary of the closing of the transaction, subject to the achievement of certain share-price targets.

The obligations of Limelight to complete the transaction are subject to the satisfaction or waiver of a number of conditions set forth in the purchase agreement, a copy of which is included as Annex A to this proxy statement, including stockholder approval of the issuance of Limelight common stock in connection with the proposed transaction (the “stock issuance proposal”).

You will also be asked to consider and vote on a proposal to: (i) elect Jeffrey T. Fisher, David C. Peterschmidt and Robert Lyons as Class III directors (the “director election proposal”); (ii) approve the ratification of Ernst & Young LLP as independent registered public accounting firm (the “ratification proposal”); and (iii) vote upon the proposal to adjourn or postpone the annual meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes to approve the stock issuance proposal (the “adjournment proposal” and together with the stock issuance proposal, director election

proposal and the ratification proposal, the “proposals”). Approval of the proposals to approve: (i) the director election proposal; (ii) ratification proposal; and (iii) if necessary or appropriate, the adjournment proposal, are not conditions to the completion of the transaction.

Your vote is very important. Please submit a proxy to vote your shares as promptly as possible so that your shares may be represented and voted at the annual meeting. The Limelight board of directors unanimously recommends that Limelight stockholders vote “FOR” each of the proposals being submitted to a vote of Limelight stockholders at the annual meeting.

Your vote is very important regardless of the number of shares that you own. We cannot complete the proposed transaction unless the proposal to approve the stock issuance proposal is approved by a majority of the votes cast by stockholders in person or via proxy with respect to this matter are cast in favor of the stock issuance proposal. The failure of any stockholder to vote in person by ballot at the annual meeting, to submit a signed proxy card or to grant a proxy electronically through the internet or by telephone will have no effect on the vote count for the proposals. If you hold your shares in “street name,” the failure to instruct your bank, broker or other nominee how to vote your shares will be counted as present and entitled to vote for purposes of determining a quorum but will have no effect on the vote count for the proposals.

This proxy statement contains detailed information about Limelight, the annual meeting, the purchase agreement and the transaction. You should read this proxy statement carefully and in its entirety before voting, including the section entitled “Risk Factors” located elsewhere in this proxy statement. We look forward to Limelight’s successful acquisition of Edgecast.

I thank you for your continued support and investment in us. Together, let’s build a great company.

Robert Lyons

PRELIMINARY PROXY STATEMENT DATED APRIL 22, 2022—SUBJECT TO COMPLETION

NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON [●], 2022

Dear Fellow Stockholder:

We are pleased to invite you to attend the annual meeting of stockholders (including any adjournments or postponements thereof, the “annual meeting”) of Limelight Networks, Inc. (“Limelight”), a Delaware corporation, which will be held at [●], on [●], 2022 at [●], Eastern time, for the following purposes:

Please refer to the proxy statement of which this notice is a part for further information on the business to be transacted at the annual meeting.

Limelight’s board of directors (the “Limelight board”) has unanimously (a) determined that the purchase agreement and the transactions contemplated by the purchase agreement, are advisable, fair to and in the best interest of Limelight’s stockholders, (b) approved and adopted the purchase agreement and the transactions contemplated by the purchase agreement, (c) directed that the approval of the stock issuance proposal be submitted to a vote at a meeting of the stockholders of Limelight entitled to vote on such matters and (d) resolved to recommend to Limelight’s stockholders to vote in favor of the approval of the stock issuance proposal on the terms and subject to the conditions set forth in the purchase agreement. The Limelight board unanimously recommends that Limelight’s stockholders vote “FOR” each of the proposals being submitted to a vote of stockholders at the annual meeting.

The Limelight board has fixed the close of business on [●], 2022 as the record date (the “record date”) for determining Limelight’s stockholders entitled to receive notice of, and to vote at, the annual meeting. Only holders of record of Limelight common stock at the close of business on the record date are entitled to receive notice of, and to vote at, the annual meeting. The presence of the holders of a

majority of the Limelight common stock issued and outstanding and entitled to vote, present in person or represented by proxy, is required to constitute a quorum for the transaction of business at the annual meeting. To ensure that your vote is counted, please provide your voting instructions as soon as possible, even if you plan to attend the annual meeting in person. We encourage you to vote via the internet or by telephone. You also have the option of voting by completing, signing, dating and returning the proxy card that accompanied the printed materials. Submitting your vote via the internet or by telephone or proxy card will not affect your right to vote in person if you decide to attend the annual meeting.

The approval of the stock issuance proposal and the ratification proposal requires the affirmative vote of the holders of a majority of the votes cast. For the director election proposal, the nominees receiving the highest number of votes will be elected to the Limelight board. Abstentions and broker non-votes will have no effect on the election of directors. The approval of the adjournment proposal, if necessary or appropriate, requires the affirmative vote of the stockholders of a majority in voting power present if a quorum is not present, or, if a quorum is present, the affirmative vote of the holders of a majority of the votes cast. Abstentions if any, will have the same effect as a vote “AGAINST” the proposals. Broker non-votes will be counted as present and entitled to vote for purposes of determining a quorum but will have no effect on the vote count for the proposals. A list of the names of Limelight’s stockholders of record will be open to the examination by any stockholder for any purpose germane to the annual meeting for ten days before the annual meeting via the Internet at www.virtualshareholdermeeting.com/LLNW2022. Such list will also be available on-line at the annual meeting during the webcast of the meeting. Your vote is very important. Whether or not you expect to attend the annual meeting, we urge you to submit a proxy to vote your shares as promptly as possible by either (1) accessing the internet website specified on your proxy card and following the on-screen instructions; (2) calling the toll-free number specified on your proxy card; or (3) signing, dating and mailing your proxy card in the postage-paid envelope provided as soon as possible, so that your shares may be represented and voted at the annual meeting.

This proxy statement provides a detailed description of the purchase agreement and the transactions contemplated thereby as well as a description of the issuance of shares of Limelight common stock to College Parent under the purchase agreement. We urge you to read this proxy statement, including any documents incorporated by reference, and the Annexes carefully and in their entirety. If you have any questions concerning the purchase agreement, the transactions contemplated thereby or this proxy statement, would like additional copies of this document, or need help voting your shares of Limelight common stock, please contact Limelight’s proxy solicitor:

SPECIAL NOTE ABOUT FORWARD-LOOKING STATEMENTS

This proxy statement and the documents that are incorporated into this proxy statement by reference contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on the current expectations, estimates and projections of Limelight Networks, Inc., (“Limelight”) about its industry, the respective beliefs of the management of Limelight and certain assumptions made by the management of Limelight. Words such as “anticipates,” “believe,” “estimate,” “expect,” “intend,” “plan,” “project,” “seek,” “target,” “goal,” “budget,” “should,” “continue,” “could,” “forecast,” “may,” “might,” “potential,” “strategy,” “will,” “would,” variations of such words and similar expressions are intended to identify such forward-looking statements. In addition, except for historical information, any statements made in this proxy statement or any of the documents that are incorporated into this proxy statement by reference about the financial condition of Limelight or expected financial results of the transaction contemplated by the Stock Purchase Agreement, dated as of March 6, 2022, by and between Limelight and College Parent, L.P. (together with its wholly-owned subsidiaries other than Edgecast, “College Parent”) a copy of which is included as Annex A to the proxy statement of which this notice is a part (the “purchase agreement”), including any projections or pro forma financial statements also are forward-looking statements. Many factors could affect the actual financial results of Limelight and cause them to vary materially from the expectations contained in the forward-looking statements, including those set forth in, or incorporated by reference into, this proxy statement. These forward-looking statements represent our intentions, plans, expectations, assumptions and beliefs about future events, including the completion of the transactions contemplated by the purchase agreement (the “transaction”), and are subject to risks, uncertainties and other factors. Many of these factors are outside our control and could cause actual results to differ materially from the results expressed or implied by these forward-looking statements. In addition to the risk factors described in the section entitled “Risk Factors” located elsewhere in this proxy statement, these factors include:

21

For any forward-looking statements made in this proxy statement or in any documents incorporated by reference, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. All subsequent written and oral forward-looking statements concerning the transaction or other matters addressed in this proxy statement and attributable to us or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this proxy statement.

You are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date of this proxy statement and should be read in conjunction with the risk factors and other disclosures contained or incorporated by reference into this proxy statement. The areas of risk and uncertainty described above, which are not exhaustive, should be considered in connection with any

22

written or oral forward-looking statements that may be made in this proxy statement or on, before or after the date of this proxy statement by us or anyone acting for us. We undertake no obligation to release publicly or otherwise make any revisions to any forward-looking statements, to report events or circumstances after the date of this proxy statement or to report the occurrence of unanticipated events, unless, and only to the extent, required by law.

Additional factors that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in reports we have filed with the SEC. For a list of the documents incorporated by reference, see the section entitled “Where You Can Find Additional Information and Incorporation of Certain Documents by Reference” located elsewhere in this proxy statement.

23

RISK FACTORS

In addition to the other information contained in this proxy statement, you should carefully consider the following risk factors in determining whether to vote for the approval of the proposal for Limelight Networks Inc. (“Limelight”) to issue its common stock, par value $0.001 per share (“Limelight common stock”), to College Parent, L.P. (together with its wholly-owned subsidiaries other than Edgecast, “College Parent”), the ultimate parent company of Edgecast Inc. (“Edgecast”), pursuant to the Stock Purchase Agreement, dated as of March 6, 2022, by and between Limelight and College Parent, a copy of which is included as Annex A to the proxy statement (the “purchase agreement”), at the annual meeting of Limelight stockholders (the “stock issuance proposal”) and the other proposals described in this proxy statement. You should also read and consider the risk factors associated with the business of Limelight because these risk factors may affect the operations and financial results of Limelight regardless of whether the transaction is consummated. These risk factors may be found under Part I, Item 1A, “Risk Factors” in Limelight’s Annual Report on Form 10-K for the year ended December 31, 2021, as updated by Limelight’s future Quarterly Reports on Form 10-Q and other future filings with the United States Securities and Exchange Commission (the “SEC”), each of which is on file or will be filed with the SEC. See the section entitled “Where You Can Find Additional Information and Incorporation of Certain Documents by Reference” for information on where you can find the documents filed by Limelight with the SEC.

Risks Relating to the Transaction

The pendency of the transaction may adversely affect the business, financial condition and results of operations of Limelight.

Uncertainty about the effect of the transaction on employees, customers, suppliers, third-party distributors and other parties, may have an adverse effect on each of the business, financial condition and results of operations of Limelight, regardless of whether the transaction is completed, and may have an adverse effect on the business, financial condition and results of operations of Limelight if the transaction is completed. These risks include the following, all of which could be exacerbated by a delay in the completion of the transaction:

24

Failure to consummate the transaction contemplated by the purchase agreement within the expected timeframe or at all could have a material adverse impact on the business, financial condition and results of operations of Limelight.

There can be no assurance that the transaction will occur within the expected timeframe or at all. Consummation of the transaction is subject to specified conditions, including:

For additional information regarding the specified conditions to the closing of the transaction (the “closing”), see the section entitled “The Stock Purchase Agreement—Conditions to the Completion of the Transaction.”

We cannot provide any assurances that these conditions will be satisfied in a timely manner or at all or that the transaction will occur.

In addition, the purchase agreement contains certain termination rights. For additional information regarding the circumstances under which Limelight and College Parent are able to terminate the purchase agreement, see the section entitled “The Stock Purchase Agreement—Termination of the Stock Purchase Agreement.” The occurrence of any event that could give rise to termination of the purchase agreement could delay or prevent the transaction from occurring at all. In addition, if the purchase agreement is terminated under certain specified circumstances, we will be required to pay College Parent a termination fee of $9.0 million.

Our executive officers and directors may have interests in the transaction other than, or in addition to, the interests of certain of our stockholders generally.

Certain members of the Limelight board of directors (the “Limelight board”) and certain of our executive officers may have interests in the transaction that are different from, or are in addition to, the interests of our stockholders generally, including as discussed under the section entitled “The Transaction—Interests of Limelight’s Directors and Executive Officers in the Transaction.” The Limelight board was aware of these interests and considered them, among other matters, in approving the purchase agreement and the transaction.

We may be unable to attract and retain key personnel and management, which could adversely impact our ability to successfully implement and execute our growth strategy.

The successful implementation of our growth strategy post-closing of the transaction will depend in large part upon the ability and experience of members of our senior management and other personnel. In addition, our performance will be dependent on our ability to identify, hire, train, motivate and retain qualified management and personnel with experience in our industry. We may be unable to attract and retain such personnel on acceptable terms, or at all. If we lose the service of qualified management or other personnel or are unable to attract and retain the necessary members of senior management or personnel post-closing of the transaction, we may not be able to successfully execute on our business strategy, which could have an adverse effect on our business.

25

Limelight may be the target of securities class action and derivative lawsuits which could result in substantial costs and may delay or prevent the transaction from being completed.

Securities class action lawsuits and derivative lawsuits are often brought against companies that have entered into agreements similar to the transaction involving a sale of a line of business or other business combinations. In addition, we may be subject to private actions, collective actions, investigations, and various other legal proceedings by stockholders, customers, employees, suppliers, competitors, government agencies, or others. Even if the lawsuits are without merit, defending against these claims can result in substantial costs, damage to our reputation, and divert significant amounts of management time and resources. If any of these legal proceedings were to be determined adversely to us, or we were to enter into a settlement arrangement, we could be exposed to monetary damages or limits on our ability to operate our business, which could have an adverse effect on our business, liquidity financial condition, and operating results. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting the closing, then that injunction may delay or prevent the transaction from being consummated, which may adversely affect Limelight’s business, financial position and results of operation. As of the date of this proxy statement, Limelight is not aware of any securities class action lawsuits or derivative lawsuits having been filed in connection with the transaction.

We have incurred and will continue to incur significant expenses in connection with the transaction, regardless of whether the transaction is completed.

We have incurred and will continue to incur significant expenses related to the transaction. These expenses include, but are not limited to, financial advisory and opinion fees and expenses, legal fees, accounting fees and expenses, certain employee expenses, consulting fees, filing fees, printing expenses and other related fees and expenses. Many of these expenses will be payable by us regardless of whether the transaction is completed.

The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and may not be an indication of Limelight’s financial condition or results of operations following the completion of the transaction.

The unaudited pro forma condensed combined financial information contained elsewhere in this proxy statement is presented for illustrative purposes only and may not be an indication of Limelight’s financial condition or results of operations following the completion of the transaction for several reasons. The unaudited pro forma condensed combined financial information has been derived from the historical financial statements of Limelight and Edgecast and adjustments and assumptions have been made regarding Limelight after giving effect to the transaction. The information upon which these adjustments and assumptions have been made is preliminary, and these kinds of adjustments and assumptions are difficult to make with accuracy. As a result, the actual financial condition and results of operations of Limelight following the completion of the transaction may not be consistent with, or evident from, the unaudited pro forma condensed combined financial information. The assumptions used in preparing the unaudited pro forma condensed combined financial information may not prove to be accurate, and other factors may affect Limelight’s financial condition or results of operations following the transaction. Any decline or potential decline in Limelight’s financial condition or results of operations may cause significant variations in the market price of the Limelight common stock.

The unaudited prospective financial information included in this proxy statement may not prove to be accurate and is not necessarily indicative of current values or future performance.

The unaudited prospective financial information of Limelight contained in this proxy statement involves risks, uncertainties and assumptions and is not a guarantee of future performance. The assumptions used in preparing the unaudited prospective financial information may not prove to be accurate, and

26

other factors may affect the business’s financial condition or results of operations following the transaction. Limelight cannot provide any assurance that the results indicated in Limelight’s unaudited prospective financial information will be realized or that the Limelight’s future financial results will not materially vary from the unaudited prospective financial information. See “Certain Unaudited Prospective Financial Information.”

Holders of our voting stock will not have appraisal or dissenters’ rights in connection with the transaction.

Neither Delaware law nor Limelight’s Amended and Restated Certificate of Incorporation provides Limelight stockholders with appraisal or dissenters’ rights in connection with the transaction.

Failure to complete the transaction could cause Limelight’s stock price to decline.

The failure to complete the transaction may create doubt as to the value of Limelight’s ability to effectively implement its current business strategies and/or a strategic transaction, which may result in a decline in Limelight’s stock price.

Risks Related to Edgecast’s Business

Edgecast’s historical financial results may not be representative of Edgecast’s results as a separate company.

Edgecast’s historical financial information included in the section entitled “Combined Financial Statements of Edgecast” located elsewhere in this proxy statement (the “Edgecast financial statements”) has been derived on a carve-out basis from the consolidated financial statements and accounting records of Verizon Media Group (“VMG”) and College Parent and does not necessarily reflect what Edgecast’s financial position, results of operations or cash flows would have been had it been a separate company during the periods presented. Edgecast operated as part of VMG and College Parent, respectively, and consisted of several entities for which separate financial statements had not historically been prepared.

The Edgecast financial statements include an allocated share of costs related to VMG or College Parent corporate functions for certain services provided to Edgecast. Expenses were allocated to Edgecast based on utilization, percentage of revenue, or other metrics deemed reasonable and appropriate by Edgecast management. The historical information does not necessarily reflect what the cost to Edgecast of these functions will be in the future, pursuant to the transition services agreement that Limelight and College Parent will enter into at the closing or otherwise.

Before September 1, 2021, Edgecast also participated in cash pooling arrangements for its domestic operations, which is reflected within financing activities in the Edgecast financial statements. Edgecast’s due to related party balances were decreased through daily cash deposits by Edgecast to VMG and increased by cash distributions and disbursements made by VMG on behalf of Edgecast for operating expenses, fees, and services provided by VMG, including information system services and other operating expenses, such as personnel costs, legal costs, marketing production, facilities costs, and insurance. This arrangement was not reflective of the manner in which Edgecast would have financed its domestic operations had it been a stand-alone business separate from VMG.

Risks Related to Customers

If Edgecast is unable to attract new customers and broaden its customer base, its business will likely be harmed.

To grow its business, Edgecast must continue to attract new customers and broaden its customer base, and generate revenue from new customers. To do so, Edgecast must successfully convince potential customers of the benefits and the value of its network, platform and products. This may require significant and costly sales efforts that are targeted at larger enterprises and senior management of these potential customers. Sales to enterprise customers may involve longer sales cycles as a result of customers requiring considerable time to evaluate Edgecast’s network, platform and products, requiring participation in a competitive purchasing process, having more formal processes for approval of purchases, and more complex requirements. Sales to mid-market businesses and small and medium businesses may involve additional challenges associated with ensuring that these customers have the necessary infrastructure and third-party relationships in place to support Edgecast’s offerings. These factors significantly impact Edgecast’s ability to add new customers and increase the time and resources, required to do so. In addition, numerous other factors, some of which are out of Edgecast’s control, may now or in the future impact its ability to acquire new customers, including potential customers’ commitments to other providers, real or perceived costs of switching to its network, platform and products, its failure to expand, retain, and motivate its sales and marketing personnel, its failure to develop or expand relationships with potential customers and channel partners, failure by Edgecast to help its customers to successfully deploy its offerings, negative media or industry or financial analyst commentary regarding Edgecast or its offerings, litigation, and deteriorating general economic conditions. If Edgecast fails to attract new customers, and fails to broaden its customer base, as a result of these and other factors its business will likely be harmed.

If Edgecast is unable to have existing customers continue and increase their use of its network, platform and products, its business will likely be harmed.

Edgecast’s ability to grow and generate incremental revenue depends on its ability to maintain and grow its relationships with its existing customers so that they continue and increase their usage of its network, platform and products. If these customers do not maintain and increase their usage of Edgecast’s network, platform and products, its revenue may decline and its results of operations will likely be harmed. In order for Edgecast to maintain or improve its results of operations, it is important that Edgecast’s customers, in particular, its enterprise customers, use Edgecast’s network, platform or products in excess of their commitment levels, if any, and continue to use Edgecast’s network, platform and products on the same or more favorable terms. Edgecast’s ability to retain its largest customers and expand their usage could be impaired for a variety of reasons, including customer budget constraints, customer satisfaction, changes in Edgecast’s customers’ underlying businesses, changes in the type and size of Edgecast’s customers, pricing changes, competitive conditions, the acquisition of its customers by other companies, governmental actions, or the possibility thereof, and general economic conditions.

Edgecast’s future success also depends in part on its ability to expand its existing customer relationships, in particular, with enterprise customers, by increasing their usage of Edgecast’s network, platform and products and selling them additional products. The rate at which Edgecast’s customers increase their usage of Edgecast’s network and platform, and purchase products from Edgecast, depends on a number of factors, including Edgecast’s ability to grow its network and platform, maintain the security and availability of its network and platform, develop and deliver new features and products, maintain customer satisfaction, general economic conditions and pricing and services offered by Edgecast’s competitors. If Edgecast’s efforts to increase usage of its network and platform by, or sell additional products to, its enterprise customers are not successful, Edgecast’s business would be

28

harmed. In addition, even if Edgecast’s largest customers increase their usage of Edgecast’s network and platform, Edgecast cannot guarantee that they will maintain those usage levels for any meaningful period of time. In addition, because many of Edgecast’s offerings endeavor to deliver increased efficiency and functionality, the successful sale of an additional products and features to an existing customer could result in a reduction of the customer’s overall usage of Edgecast’s network and platform.

Edgecast receives a substantial portion of its revenues from a limited number of customers, and the loss of, or a significant reduction in usage by, one or more of its major customers would result in lower revenues and could harm its business.

Edgecast’s future success is dependent on establishing and maintaining successful relationships with a diverse set of customers. However, Edgecast currently receives a substantial portion of its revenues from a limited number of customers. For the year ended December 31, 2020, Edgecast’s top three customers accounted for approximately 46.4% of its revenue. For the period from January 1, 2021 to August 31, 2021, Edgecast’s top three customers accounted for approximately 45.4% of its revenue and, for the period from September 1, 2021 to December 31, 2021, Edgecast’s top three customers accounted for approximately 41% of its revenue. It is likely that Edgecast will continue to be dependent upon a limited number of customers for a significant portion of its revenues for the foreseeable future and, in some cases, the portion of its revenues attributable to individual customers may increase in the future. In addition, changes to Edgecast’s customers’ business may cause Edgecast’s revenues attributable to individual customers to increase, including any impact from merger and acquisition activities, internal business reorganizations leading to operational and decision making changes, and corporate structure changes such as subsidiary consolidation and reorganization that may arise in the future. The loss of one or more key customers or a reduction in usage by any major customers would significantly reduce Edgecast’s revenues.

If current and potential large customers shift to hardware-based or other DIY internal solutions, Edgecast’s business will be negatively impacted.

Edgecast is reliant on large customers to direct traffic to its network for a significant part of its revenues. In the past, some of those customers have determined that it is better for them to employ a “do-it-yourself” or “DIY” strategy by putting in place equipment, software and other technology solutions for content and application delivery and security protection within their internal systems instead of using Edgecast’s products for some or all of their needs. Essentially, this is another form of competition for Edgecast. As the amount of money a customer spends with Edgecast increases, the risk that they will seek alternative products such as DIY or a multi-vendor policy likewise increases. If additional large customers shift to this model, traffic on Edgecast’s network and its contracted revenue commitments would decrease, which would negatively impact Edgecast’s business, profitability, financial condition, results of operations and cash flows.

Edgecast provides service level commitments under its customer agreements. If Edgecast fails to meet these contractual commitments, Edgecast could be obligated to provide credits, or face contract termination with refunds, which could harm its business.

Most of Edgecast’s customer agreements contain service level commitments. If Edgecast is unable to meet the stated service level commitments, Edgecast may be contractually obligated to provide the affected customers with service credits, which could significantly affect its revenues. Edgecast could also face customer terminations with refunds, which could significantly affect both its current and future revenues. Any service level failures could harm Edgecast’s business.

29

Edgecast’s ability to maintain customer satisfaction depends in part on the quality of its customer support. Failure to maintain high-quality customer support could have an adverse effect on Edgecast’s business, results of operation, and financial condition.

Edgecast believes that the successful use of its network, platform and products requires a high level of support and engagement for many of its customers, particularly its enterprise customers. In order to deliver appropriate customer support and engagement, Edgecast must successfully assist its customers in deploying and continuing to use its network, platform and products, resolving performance issues, addressing interoperability challenges with the customers’ existing IT infrastructure, and responding to security threats and cyber-attacks and performance and reliability problems that may arise from time to time. The IT architecture of Edgecast’s contracted customers, particularly enterprise customers, is very complex and may require high levels of focused support to effectively utilize Edgecast’s network, platform and products. Increased demand for customer support, without corresponding increases in revenue, could increase Edgecast’s costs and adversely affect its business, results of operations, and financial condition.

Edgecast also relies on channel partners in order to provide frontline support to some of its customers, including in regions where Edgecast does not have a significant physical presence or the customers primarily speak languages other than English. If Edgecast’s channel partners do not provide support to the satisfaction of Edgecast’s customers, Edgecast may be required to hire additional personnel and to invest in additional resources in order to provide an adequate level of support, generally at a higher cost than that associated with Edgecast’s channel partners. There can be no assurance that Edgecast will be able to hire sufficient support personnel as and when needed, particularly if its sales exceed its internal forecasts. To the extent that Edgecast is unsuccessful in hiring, training, and retaining adequate support resources, its ability to provide high-quality and timely support to its customers will be negatively impacted, and its customers’ satisfaction with its network, platform and products could be adversely affected. Any failure to maintain high-quality customer support, or a market perception that Edgecast does not maintain high-quality customer support, could adversely affect Edgecast’s reputation, business, results of operations, and financial condition, particularly with respect to its large customers.

If Edgecast cannot maintain compatibility with its customers’ IT infrastructure, including their chosen third-party applications, its business will be harmed.

Edgecast’s network, platform and products interoperate with its customers’ IT infrastructure, that often has different specifications, utilizes diverse technology, and requires compatibility with multiple communication protocols. Therefore, the functionality of Edgecast’s technology often needs to have, and maintain, compatibility with its customers’ technology environment, including their chosen third-party technology. Customers, and in particular these chosen third-party applications, may change features, restrict Edgecast’s access to, or alter their applications in a manner that causes incompatibilities or causes Edgecast significant costs to maintain compatibility, and as a result Edgecast’s business could be adversely affected. Such changes could functionally limit or prevent the compatibility of Edgecast’s network, platform and products with its customers’ IT infrastructure, which would negatively affect adoption of Edgecast’s network, platform and products and harm Edgecast’s business. If Edgecast fails to update its offerings to achieve compatibility with new third-party applications that its customers use, Edgecast may not be able to offer the functionality that its customers need, which could harm Edgecast’s business.

30

Risks Related to Market Dynamics

Edgecast operates in emerging and evolving markets, which may develop more slowly or differently than expected. If Edgecast’s markets do not grow as expected, or if Edgecast cannot expand its network, platform and products to meet the demands of these markets, its revenue may decline, or fail to grow.

The markets for Edgecast’s network, platform and products are constantly evolving and characterized by rapid changes in technology, customer requirements, industry standards, and frequent introductions of new, and improvements of existing, products, making its business and prospects difficult to evaluate. For example, the number of people who access the internet through devices other than PCs, including mobile devices, game consoles, and television set-top devices continues to increase dramatically. The capabilities of these devices are advancing exponentially, and the increasing need to provide a high-quality video experience will present Edgecast with significant challenges. If Edgecast is unable to deliver its offerings to a substantial number of alternative device users and at a high quality, or if Edgecast is slow to develop services and technologies that are more compatible with these devices, Edgecast may fail to capture a significant share of an important portion of the growing market. Such a failure could limit Edgecast’s ability to compete effectively in an industry that is rapidly growing and evolving, which, in turn, could harm its business.

Similarly, the market for edge computing is in an early stage of development. There is considerable uncertainty over the size and rate at which this market will grow, as well as whether Edgecast’s platform will be widely adopted. Edgecast’s success will depend, to a substantial extent, on the widespread adoption of its platform. Some organizations may be reluctant or unwilling to use Edgecast’s platform for a number of reasons, including concerns about additional costs, uncertainty regarding the reliability, and security or lack of awareness of the benefits of Edgecast’s platform. Moreover, many organizations have invested substantial personnel and financial resources to integrate traditional on-premise services into their businesses, and therefore may be reluctant or unwilling to migrate to Edgecast’s services.

Edgecast’s ability to expand sales of its network, platform and products into new and existing markets depends on several factors, including potential customer awareness of its offerings; introduction and market acceptance of enhancements to its network, platform or new products that Edgecast may introduce; its ability to attract, retain and effectively train sales and marketing personnel; its ability to develop relationships with partners; the effectiveness of its marketing programs; the pricing of its services; and the success of its competitors. If Edgecast is unsuccessful in developing and marketing its network, platform or products into new and existing markets, or if organizations do not perceive or value the benefits of its network, platform or products, the market for these offerings might not continue to develop or might develop more slowly than Edgecast expects, either of which may harm its business.

Edgecast faces significant competition and may be unsuccessful against current and future competitors. If Edgecast does not compete effectively, its operating results and future growth could be harmed.

Competition is intense in the markets that Edgecast operates in and with the introduction of new technologies and market entrants, Edgecast expects competition to further intensify in the future. In addition, some of Edgecast’s competitors may make acquisitions, be acquired, or enter into strategic relationships to offer a more comprehensive service than Edgecast does. These combinations may make it more difficult for Edgecast to compete effectively. Edgecast expects these trends to continue as competitors attempt to strengthen or maintain their market positions.

Demand for many of Edgecast’s offerings is sensitive to price. Many factors, including Edgecast’s marketing, customer acquisition and technology costs, commoditization of its products and services

31

and its current and future competitors’ pricing and marketing strategies, can significantly affect Edgecast’s pricing strategies. There can be no assurance that it will not be forced to engage in price-cutting initiatives, or to increase its marketing and other expenses to attract and retain customers in response to competitive pressures, either of which could have a material adverse effect on Edgecast’s revenue, operating results and resources.

Edgecast may have difficulty scaling and adapting its existing infrastructure to accommodate increased traffic and storage, technology advances or customer requirements.

In the future, advances in technology, increases in traffic and storage, and new customer requirements may require Edgecast to change its infrastructure, expand its infrastructure or replace its infrastructure entirely. Scaling and adapting Edgecast’s infrastructure is likely to be complex and require additional technical expertise. If Edgecast is required to make any changes to its infrastructure, it may incur substantial costs and experience delays or interruptions in its service. These delays or interruptions may cause customers and partners to become dissatisfied with Edgecast’s service and move to competing service providers. Edgecast’s failure to accommodate increased traffic and storage, increased costs, inefficiencies or failures to adapt to new technologies or customer requirements and the associated adjustments to its infrastructure could harm its business, financial condition and results of operations.

Edgecast faces risks associated with global operations and will face increased risks as Edgecast expands its presence outside the United States.

Edgecast’s operations in foreign countries subject Edgecast to risks that may increase its costs, disrupt its operations or make its operations less efficient and require significant management attention. These risks include:

32

Edgecast’s foreign operations subject Edgecast to laws and regulations worldwide that differ among jurisdictions, affecting its operations in areas such as intellectual property ownership and infringement; tax; anti-corruption; internet and technology regulations; foreign exchange controls and cash repatriation; data privacy; competition; and employment. Compliance with such requirements can be onerous and expensive and may otherwise impact Edgecast’s business operations negatively. Although Edgecast has, and will continue to develop, policies, controls, and procedures designed to help ensure compliance with applicable laws, there can be no assurance that its employees, contractors, suppliers or agents will not violate such laws or Edgecast’s policies. Violations of these laws and regulations can result in fines; criminal sanctions against Edgecast, its officers or its employees; prohibitions on the conduct of Edgecast’s business; and damage to Edgecast’s reputation. As Edgecast continues to grow its foreign operations, it will face increased exposure to the risks discussed above.

Risks Related to Third Parties

Edgecast’s business strategy depends on the ability to source adequate network capacity and the equipment it needs to operate its network; failure to have access to those resources could lead to loss of revenue and service disruptions.

To operate Edgecast’s network, Edgecast is dependent in part upon network capacity provided by third-party telecommunications network providers, the availability of co-location facilities to house its servers and equipment to support its operations. Edgecast may be unable to purchase the bandwidth and space it needs from these providers due to limitations on their resources or other reasons outside of Edgecast’s control. Inability to access facilities where Edgecast would like to install servers, or perform maintenance on existing servers, because of governmental restrictions on access due to stay-at-home orders or social distancing requirements due to the ongoing COVID-19 pandemic or other events impedes Edgecast’s ability to expand or maintain capacity. As a result, there can be no assurance that Edgecast is adequately prepared for unexpected increases in bandwidth demands by its customers, particularly those under cyber-attack or impacted by pandemic-related events. Failure to put in place the capacity Edgecast requires to operate its business effectively could result in a reduction in, or disruption of, service to its customers and ultimately a loss of those customers.

Edgecast’s network, platform and products rely on hardware equipment, including servers deployed around the world. Global supply chain constraints in the wake of the COVID-19 pandemic continue to increase lead times for equipment components, which adds risk to Edgecast’s ability to flex to meet future business needs. Disruptions in Edgecast’s supply chain could prevent Edgecast from purchasing needed equipment at attractive prices or at all. For example, from time to time, it has been, and may continue to be, more difficult to purchase equipment that is manufactured in areas that face disruptions to operations due to unrest or other political activity, public health issues (such as the ongoing COVID-19 pandemic), safety issues, natural disasters or general economic conditions. Failure to have adequate equipment, including server equipment, could harm the quality of Edgecast’s services, which could lead to the loss of customers and revenue.

33

Edgecast utilizes third-party technology in its business, and failures or vulnerabilities, and/or litigation, related to these technologies may adversely affect its business.

Edgecast utilizes third party technology software, services, and other technology in order to operate critical functions of its business, including the integration of certain of these technologies into its network, platform and products. If these software, services, or other technology become unavailable or contain vulnerabilities, Edgecast’s expenses could increase and its ability to operate its network, provide its products, and its results of operations could be impaired until equivalent software, technology, or services are purchased or developed or any identified vulnerabilities are remedied. If Edgecast is unable to procure the necessary third-party technology it may need to acquire or develop alternative technology, it may have to resort to utilizing alternative technology of lower quality. This could limit and delay Edgecast’s ability to offer new or competitive products and increase its costs of providing services. As a result, Edgecast’s business could be significantly harmed. In addition, the use of third-party technology may expose Edgecast to third-party claims of intellectual property infringement which could cause Edgecast to incur significant costs in defense or alternative sourcing.

Edgecast’s growth depends, in part, on the success of its strategic relationships with third parties, and if Edgecast fails to continue to expand, grow, and retain these relationships then its business, results of operations, and financial condition may be adversely impacted.

To grow its business, Edgecast anticipates that it will continue to depend on relationships with third parties, such as value-added channel partners, resellers, referral partners, systems integrators, global platform providers, telecommunications companies, and managed security service providers. Developing, expanding, and retaining these strategic relationships has played, and will continue to play, an increasingly greater role in Edgecast’s sales efforts to its enterprise customers. However, identifying these types of strategic partners, negotiating and documenting business and contractual relationships with them, and monitoring the actions of Edgecast’s partners and their relationships with Edgecast’s end-customers, each require significant time and resources. Edgecast’s competitors also may be effective in providing incentives to third parties to favor their offerings over Edgecast’s offerings. In addition, acquisitions of such partners by Edgecast’s competitors could result in a decrease in the number of Edgecast’s current and potential customers, as these partners may no longer facilitate the adoption of Edgecast’s offerings by potential customers. Further, some of Edgecast’s partners are or may become competitive with certain of Edgecast’s offerings and may elect to no longer integrate with Edgecast’s network, platform and products. If Edgecast is unsuccessful in establishing, expanding, or maintaining its relationships with these third parties, its ability to compete in the marketplace or to grow its revenue could be impaired, and its business, results of operations, and financial condition may suffer. Even if Edgecast is successful, it cannot guarantee that these relationships will result in increased customer usage of its network, platform and products by, or increased revenue from, its customers.

Edgecast relies on certain “open-source” software, the use of which could result in it having to distribute its proprietary software, including its source code, to third parties on unfavorable terms, which could materially affect its business.

Certain of Edgecast’s offerings use software that is subject to open-source licenses. Open-source code is software that is freely accessible, usable and modifiable; however, certain open-source code is governed by license agreements, the terms of which could require users of such software to make any derivative works of the software available to others on unfavorable terms or at no cost. Because Edgecast uses open-source code, it may be required to take remedial action in order to protect its proprietary software. Such action could include replacing certain source code used in Edgecast’s software, discontinuing certain of Edgecast’s offerings or taking other actions that could be expensive and divert resources away from Edgecast’s development efforts. In addition, the terms relating to

34

disclosure of derivative works in many open-source licenses are unclear and have not been interpreted by U.S. courts. If a court interprets one or more such open-source licenses in a manner that is unfavorable to Edgecast, Edgecast could be required to make certain of its key software available at no cost. Edgecast could also be subject to similar conditions or restrictions should there be any changes in the licensing terms of the open source software incorporated into its network, platform or products. In either event, Edgecast could be required to seek licenses from third parties in order to continue offering its offerings, to re-engineer its offerings or to discontinue the sale of its offerings in the event re-engineering cannot be accomplished on a timely or successful basis, any of which could adversely affect Edgecast’s business, operating results and financial condition. Furthermore, open-source software may have security flaws and other deficiencies that could make Edgecast’s offerings less reliable and damage its business.

Risks Related To Cybersecurity And Defects

Actual or perceived breaches or failures of Edgecast’s internal systems, networks, or data could cause its network, platform or products to be perceived as insecure, underperforming, or unreliable, Edgecast’s customers to lose trust in its network, platform and products, its reputation to be damaged, and its financial results to be negatively impacted.

Edgecast faces security threats from malicious third parties that could obtain unauthorized access to its internal systems, networks, and data. It is virtually impossible for Edgecast to entirely mitigate the risk of these security threats and the security, performance, and reliability of its network, platform and products may be disrupted by third parties, including nation-states, competitors, hackers, disgruntled employees, former employees, or contractors. Edgecast also faces the possibility of security threats from other sources, such as employee or contractor errors, or malfeasance. For example, hostile third parties, including nation-states, may seek to bribe, extort, or otherwise manipulate Edgecast’s employees or contractors to compromise its network, platform and products. In addition, as Edgecast’s business grows and it employs more employees in more countries around the world, its ability to supervise the actions of its employees will decrease and the risk of an employee or contractor error or act of malfeasance will increase. These security threats from third parties are also likely to increase as the numbers, sizes, and types of customers using Edgecast’s network, platform and products increases, particularly those customers that are involved in particularly sensitive industries or activities, such as banking and finance companies and governmental entities. While Edgecast has implemented security measures internally and has integrated security measures into its network, platform and products, these measures may not function as expected and may not detect or prevent all unauthorized activity, prevent all security breaches or incidents, mitigate all security breaches or incidents, or protect against all attacks or incidents.

The global network that Edgecast uses to provide its offerings to its customers is made up of equipment at co-location facilities located worldwide and Edgecast expects to continue to increase the size of its network in the future. As Edgecast grows the size and scope of its network, the number of its employees and third party contractors that have access to its equipment at these facilities will continue to increase, which will also increase the risk of potential errors or malfeasance such as potential equipment theft or potential attempts to interfere with, or intercept, network and customer data that is held in, or flows through, this equipment. In addition, local government officials may attempt to, or successfully take control of, Edgecast’s equipment in an attempt to interfere with its services or intercept data. Edgecast may also experience security breaches and other incidents that may remain undetected for an extended period and, therefore, may have a greater impact on Edgecast’s offerings and the networks and systems used in its business, and the proprietary and other confidential data contained on its network or otherwise stored or processed in its operations, and ultimately on its business. Edgecast expects to incur significant costs in its efforts to detect and prevent security breaches and other security-related incidents, and Edgecast may face increased costs in the event of

35

an actual or perceived security breach or other security related incident. Edgecast’s internal systems are exposed to the same cybersecurity risks and consequences of a breach as the systems of Edgecast’s customers and other enterprises, any of which could have an adverse effect on Edgecast’s business or reputation. These cybersecurity risks pose a particularly significant risk to a business like Edgecast that is focused on providing highly secure products to customers. With the increase in remote work during the ongoing COVID-19 pandemic, Edgecast and its customers face increased risks to the security of infrastructure and data, and Edgecast cannot guarantee that its security measures will prevent security breaches or incidents. Edgecast also may face increased costs relating to maintaining and securing its infrastructure and data that Edgecast maintains and otherwise processes.

There can be no assurance that any security measures that Edgecast or its third-party service providers have implemented will be effective against current or future security threats, and Edgecast cannot guarantee that its systems and networks or those of its third-party service providers have not been breached or otherwise compromised, or that they and any software in Edgecast or Edgecast’s supply chains do not contain bugs, vulnerabilities, or compromised code that could result in a breach of or disruption to Edgecast’s systems and networks or the systems and networks of third parties that support Edgecast and its services. Unauthorized access to, other security breaches of, or security incidents affecting, systems, networks, and data used in Edgecast’s business, including those of its vendors, contractors, or those with which Edgecast has strategic relationships, even if not resulting in an actual or perceived introduction of ransomware, malware, or other malicious code or other actual or perceived breach of its customers’ networks, systems, or data, could result in the loss, compromise, corruption or other unavailability of data, disruptions to Edgecast’s and its customers’ products, systems, networks, and operations, loss of business, reputational damage adversely affecting customer or investor confidence, regulatory investigations and orders, litigation, indemnity obligations, damages for contract breach, penalties for violation of applicable laws or regulations, significant costs for remediation, and other liabilities.

Actual or perceived problems with Edgecast’s network, platform or products, or those of its vendors, contractors, or those with which Edgecast has strategic relationships, could result in actual or perceived breaches of Edgecast’s or its customers’ networks and systems or data. Actual or perceived breaches or other security incidents from these or other causes could lead to claims and litigation, indemnity obligations, regulatory audits, proceedings, and investigations and significant legal fees, significant costs for remediation, the expenditure of significant financial resources in efforts to analyze, correct, eliminate, remediate, or work around errors or defects, to address and eliminate vulnerabilities, and to address any applicable legal or contractual obligations relating to any actual or perceived security breach or incident. They also could damage Edgecast’s relationships with its existing customers and have a negative impact on Edgecast’s ability to attract and retain new customers. Because Edgecast’s business is focused on providing secure and high performing network services to its customers, Edgecast believes that its products and the networks and systems it uses in its business could be targets for hackers and others, and that an actual or perceived breach of, or security incident affecting, its networks, systems, or data, could be especially detrimental to its reputation, customer and channel partner confidence in its solution, and its business. Additionally, Edgecast’s offerings are designed to operate without interruption. If a breach or security incident were to impact the availability of Edgecast’s network, platform and products, its business, results of operations, and financial condition, as well as its reputation, could be adversely affected. Any cybersecurity insurance that Edgecast carries may be insufficient to cover all liabilities incurred by Edgecast in connection with any privacy or cybersecurity incidents or may not cover the kinds of incidents for which Edgecast submits claims.

36

Real or perceived errors, failures or bugs in Edgecast’s customer solutions, software or technology could adversely affect its business, financial condition and results of operations.

Edgecast’s network, platform and products may experience errors, failures, vulnerabilities, or bugs that cause its offerings not to perform as intended and the likelihood of these problems may increase as Edgecast continues to expand the number and complexity of products that it offer to its customers through its global network. Although events like this are outside Edgecast’s control, they could materially harm its reputation and diminish the confidence of its current and potential customers in its network, platform and products. In addition, deployment of Edgecast’s network, platform and products into other computing environments may expose these errors, failures, vulnerabilities, or bugs in its offerings. Any such errors, failures, vulnerabilities, or bugs may not be found until after they are deployed to Edgecast’s customers and may create the perception that Edgecast’s network, platform and products are insecure, underperforming, or unreliable. In addition, in the event network outages or similar events occur, these events can require additional capital expenditures to lessen the chance that similar events will occur in the future. Edgecast also provides frequent updates and enhancements to its network, platform and products, which increase the possibility of errors. Edgecast’s quality assurance procedures and efforts to report, track, and monitor issues with its network may not be sufficient to ensure it detects any such defects in a timely manner.

Risks Related to Edgecast’s Operations

If Edgecast is unable to sell its services at acceptable prices relative to its costs, its revenue and gross margins will decrease and its business and financial results will suffer.

Edgecast operates in a multi-content delivery network supplier environment, where customers can route traffic to Edgecast, or away from it, within seconds. This results in on-going price compression. Simultaneously, Edgecast invests significant amounts in purchasing capital equipment as part of its effort to increase the capacity of its global network. The investments in Edgecast’s infrastructure are based upon assumptions regarding future demand, anticipated network utilization, as well as prices that Edgecast will be able to charge for its services. These assumptions may prove to be wrong. If the price that Edgecast is able to charge customers to deliver their content falls to a greater extent than anticipated, if Edgecast over-estimates future demand for its services, is unable to achieve an acceptable rate of network utilization, or if costs to deliver services do not fall commensurate with any future price declines, Edgecast may not be able to achieve acceptable rates of return on its infrastructure investments, and its gross profit and results of operations may suffer dramatically.

As Edgecast further expands its global network and services, and refresh its network equipment, Edgecast is dependent on significant future growth in demand for its services to justify additional capital expenditures. If Edgecast fails to generate significant additional demand for its services, its results of operations will suffer, and Edgecast may fail to achieve planned or expected financial results.

A significant portion of Edgecast’s revenue is derived collectively from its streaming, security, edge computing and support services. These services tend to have higher gross margins than Edgecast’s network services. Edgecast may not be able to achieve the growth rates in revenue from such services that it expects or has experienced in the past. If Edgecast is unable to achieve the expected growth rates in revenue for these service offerings, Edgecast’s revenue and operating results could be significantly and negatively affected.

If Edgecast is unable to recruit and retain key employees and qualified sales, research and development, technical, marketing and support personnel, its ability to compete could be harmed.

Edgecast’s future success depends upon the services of its key technology, sales, research and development, marketing and support personnel. Like other companies in Edgecast’s industries,

37

Edgecast has experienced, and expects to continue to experience, difficulty in hiring and retaining highly skilled employees with appropriate qualifications, and, if Edgecast fails to attract new personnel or fails to retain and motivate its current personnel, its business and future growth prospects could suffer.

In addition, Edgecast’s future success will depend upon its ability to attract and retain employees. Such efforts will require time, expense and attention by Edgecast’s employees as there is significant competition for talented individuals, which affects both Edgecast’s ability to retain key employees and hire new ones and new hires require significant training. This competition may result in increased costs in the form of cash and stock-based compensation. The loss of the services of a significant number of Edgecast’s employees or any of its key employees or its inability to attract and retain new talent in a timely fashion may be disruptive to Edgecast’s operations and overall business.

Risks Related to Edgecast’s Reputation

Edgecast could be harmed if its reputation is damaged.

Edgecast’s corporate reputation is susceptible to material damage by events such as disputes with customers or competitors, cyber-attacks or service outages, internal control deficiencies, delivery failures, compliance violations, government investigations or legal proceedings. Similar events impacting one of Edgecast’s competitors could result in negative publicity for entire industry in which Edgecast operates, indirectly harming Edgecast’s business. Edgecast may also experience reputational damage if customers, vendors, employees, advocacy groups, regulators, investors, the media, social media influencers or others criticize its services, operations or public positions.

There is a risk that negative or inaccurate information about Edgecast’s business, even if based on rumor or misunderstanding, could adversely affect its business. Damage to Edgecast’s reputation could be difficult, expensive and time-consuming to repair. Damage to Edgecast’s reputation could also reduce the value and effectiveness of its brand name and could reduce investor confidence in Edgecast.

Edgecast’s dedication to its values may negatively influence its financial results.

Edgecast has taken, and may continue to take, actions that Edgecast believes are in the best interests of its customers, its employees, and its business, even if those actions do not maximize financial results in the short term. For instance, Edgecast has decided in the past, and may decide in the future, not to work with certain customers that do not align with Edgecast’s values or strategy. However, this approach may not result in the benefits that Edgecast expects, and its employees or third parties may disagree with these decisions, and Edgecast’s business could be adversely affected.

Legal and Regulatory Risks

Evolving privacy regulations could negatively impact Edgecast’s profitability and business operations.

Laws and regulations that apply to the internet related to privacy and data localization could pose risks to Edgecast’s revenues, intellectual property and customer relationships, as well as increase expenses or create other disadvantages to Edgecast’s business.

Privacy laws are rapidly proliferating, changing and evolving globally. Governments, privacy advocates and class action attorneys are increasingly scrutinizing how companies collect, process, use, store, share and transmit personal data. Laws, such as the European Union General Data Protection Regulation (“GDPR”), and the California Consumer Privacy Act of 2018 (“CCPA”), and industry self-regulatory codes have been enacted, and more laws are being considered that may affect how

38

Edgecast uses data generated from its network, platform and products as well as its ability to reach current and prospective customers, understand how its offerings are being used and respond to customer requests allowed under the laws. Any perception that Edgecast’s business practices, its data collection activities or how its offerings operate represent an invasion of privacy, whether or not consistent with current regulations and industry practices, may subject Edgecast to public criticism or boycotts, class action lawsuits, reputational harm or actions by regulators, or claims by industry groups or other third parties, all of which could disrupt its business and expose Edgecast to liability.

Engineering efforts to build new capabilities to facilitate compliance with increasing data localization requirements and new and changing privacy laws could require Edgecast to take on substantial expense and divert engineering resources from other projects. Edgecast might experience reduced demand for its offerings if Edgecast is unable to engineer products that meet its legal duties or help its customers meet their obligations under the GDPR, the CCPA or other data regulations, or if the changes Edgecast implements to comply with such laws and regulations make its offerings less attractive.

Edgecast’s ability to leverage the data generated by its global network of servers is important to the value of many of its offerings, its operational efficiency and future product development opportunities. Edgecast’s ability to use data in this way may be constrained by regulatory developments. Compliance with applicable laws and regulations regarding personal data may require changes in services, business practices or internal systems that result in increased costs, lower revenue, reduced efficiency or greater difficulty in competing with other firms. Compliance with data regulations might limit Edgecast’s ability to innovate or offer certain features and functionality in some jurisdictions where Edgecast operates. Failure to comply with existing or new rules may result in significant penalties or orders to stop the alleged non-compliant activity, as well as negative publicity and diversion of management time and effort.

Although Edgecast takes steps intended to improve the security controls across its business groups and geographies, Edgecast’s security controls over personal data, its training of employees and third parties on data security and other practices Edgecast follows may not prevent the improper disclosure or misuse of customer or end-user data Edgecast stores and manages. Improper disclosure or misuse of personal data could harm Edgecast’s reputation, lead to legal exposure to customers or end users, or subject Edgecast to liability under laws that protect personal data, resulting in increased costs or loss of revenue.

Other regulatory developments could negatively impact Edgecast’s business.

Local and foreign laws and regulations that apply to the internet related to, among other things, content liability, security requirements, law enforcement access to information, critical infrastructure, data localization requirements and restrictions on social media or other content could pose risks to Edgecast’s revenues, intellectual property and customer relationships as well as increase expenses or create other disadvantages to its business. Section 230 of the U.S. Communications Decency Act, often referred to as Section 230, gives websites that host user-generated content broad protection from legal liability for content posted on their sites. Proposals to repeal or amend Section 230 could expose Edgecast to greater legal liability in the conduct of its business. Regulations have been enacted or proposed in a number of countries that limit the delivery of certain types of content into those countries. Enactment and expansion of such laws and regulations would negatively impact Edgecast’s revenues. In addition, such laws and regulations could cause internet service providers, or others, to block Edgecast’s offerings in order to enforce content blocking efforts. In addition, efforts to block a single product or domain name may end up blocking a number of other products or domain names in an overbroad manner that could affect Edgecast’s business. Interpretations of laws or regulations that would subject Edgecast to regulatory supervision or, in the alternative, require Edgecast to exit a line of

39

business or a country, could lead to loss of significant revenues and have a negative impact on the quality of Edgecast’s network, platform and products. As noted with privacy compliance above, engineering efforts to build new capabilities to facilitate compliance with law enforcement access requirements, content access restrictions, or other regulations could require Edgecast to take on substantial expense and divert engineering resources from other projects. These circumstances could harm Edgecast’s profitability.

Edgecast may not be successful in protecting and enforcing its intellectual property rights.

Edgecast relies on various patents, copyrights, trade names, trademarks, service marks, trade secrets and other similar intellectual property rights, as well as confidentiality agreements and procedures, to establish and protect its proprietary rights. For a variety of reasons, however, these steps may not fully protect Edgecast, including due to inherent limitations on the ability to enforce these rights. Furthermore, Edgecast may from time to time be subject to intellectual property infringement and other claims and related litigation. Edgecast has also agreed to indemnify its customers and certain strategic partners if its offerings infringe or misappropriate specified intellectual property rights. As a result, Edgecast may become involved in litigation or claims brought against customers or strategic partners if its offerings or technology are the subject of such allegations. If Edgecast is unsuccessful in protecting or enforcing its intellectual property rights, its business, competitive position, results of operations and financial condition could be adversely affected.

THE ANNUAL MEETING

This proxy statement is being provided to Limelight stockholders as part of a solicitation of proxies by the Limelight board for use at the annual meeting of Limelight stockholders (the “annual meeting”) to be held at the time and place specified below, and at any properly convened meeting following an adjournment or postponement thereof. This proxy statement and the information incorporated by reference herein provides our stockholders with the information they need to know to be able to vote or instruct their vote to be cast at the annual meeting.

Date, Time and Place

The annual meeting will be held on [●], 2022, at [●], Eastern Time, virtually via www.virtualshareholdermeeting.com/LLNW2022, where you, or your proxy, will be able to attend the annual meeting and vote electronically. Please note that you will not be able to attend the annual meeting in person. The annual meeting will begin online promptly at [●], Eastern Time.

Stockholders will be able to listen, vote, and submit questions from their home or from any remote location that has Internet connectivity.

A list of stockholders entitled to vote at the annual meeting will be available for examination by any stockholder for any purpose germane to the annual meeting beginning ten days prior to the annual meeting, and ending on the date of the annual meeting via the Internet at www.virtualshareholdermeeting.com/LLNW2022, subject to the satisfactory verification of stockholder status. Such list will also be available on-line at the annual meeting during the webcast of the meeting.

Purpose of the Annual Meeting

At the annual meeting, and any adjournments or postponements thereof, you will be asked to consider and vote on:

Recommendation of the Limelight Board

The Limelight board, after careful consideration of the various factors described under “The Transaction—Recommendation of the Limelight Board and Its Reasons for the Transaction” located elsewhere in this proxy statement, at a meeting held on March 6, 2022, unanimously determined that the purchase agreement and the transactions contemplated by the purchase agreement and the issuance of shares of Limelight common stock in the transaction are advisable, fair to and in the best interests of Limelight stockholders; approved and adopted the purchase agreement and the transactions contemplated by the purchase agreement, including the issuance of shares of Limelight common stock pursuant to the purchase agreement, directed that the approval of the issuance of shares of Limelight common stock be submitted to a vote at a meeting of Limelight stockholders entitled to vote on such matters and resolved to recommend to Limelight stockholders to vote in favor of the approval of the stock issuance proposal.

43

In evaluating the transaction, the Limelight board consulted with and received the advice of Limelight’s outside legal and financial advisors, held discussions with Limelight’s management and considered a number of factors that it believed supported its decision to enter into the purchase agreement. These factors included, but were not limited to, those listed in “The Transaction—Recommendation of the Limelight Board and Its Reasons for the Transaction” located elsewhere in this proxy statement.

Accordingly, the Limelight board unanimously recommends that you vote “FOR” the stock issuance proposal, “FOR” the director election proposal, “FOR” the ratification proposal and “FOR” the adjournment proposal.

Record Date; Stockholders Entitled to Vote

Only holders of record of Limelight common stock at the close of business on [●], 2022, the record date for the annual meeting (the “record date”), will be entitled to notice of, and to vote at, the annual meeting, or any adjournment or postponement thereof. At the close of business on the record date, [●] shares of Limelight common stock were issued and outstanding and held by [●] holders of record.

Holders of record of Limelight common stock on the record date are entitled to one vote per share at the annual meeting on each proposal. A list of the names of our stockholders of record will be open to the examination by any stockholder for any purpose germane to the annual meeting for ten days before the annual meeting via the Internet at www.virtualshareholdermeeting.com/LLNW2022. Such list will also be available on-line at the annual meeting during the webcast of the meeting. Our stockholder list will also be available at the annual meeting for examination by any stockholder present at such meeting.

Voting by our Directors and Executive Officers

At the close of business on the record date, our directors and executive officers were entitled to vote [●] shares of Limelight common stock, or approximately [●]% of the shares of Limelight common stock outstanding on that date. We currently expect that all of our directors and executive officers will vote their shares in favor of each proposal being submitted to a vote of our stockholders at the annual meeting, although none of them has entered into any agreement obligating them to do so.

Quorum

No business may be transacted at the annual meeting unless a quorum is present. The presence of the holders of a majority of the stock issued and outstanding and entitled to vote, present in person or represented by proxy, is required to constitute a quorum for the transaction of business at the annual meeting. If a quorum is not present, or if there are not sufficient votes at the time of the annual meeting to approve the stock issuance proposal, the annual meeting may be adjourned to allow more time for obtaining additional proxies or votes. At any subsequent reconvening of the annual meeting, all proxies will be voted in the same manner as they would have been voted at the original convening of the annual meeting, except for any proxies that have been effectively revoked or withdrawn before the adjourned meeting.

Abstentions (shares of Limelight common stock for which proxies have been received but for which the holders have abstained from voting) will be included in the calculation of the number of shares of Limelight common stock represented at the annual meeting for purposes of determining whether a quorum has been achieved. Broker non-votes will be counted as present and entitled to vote for purposes of determining a quorum but will have no effect on the vote count for the proposals.

44

Required Vote

The approval of the stock issuance proposal and the ratification proposal requires the affirmative vote of the holders of a majority of the votes cast. For the director election proposal, the nominees receiving the highest number of votes will be elected to the Limelight board. The approval of the adjournment proposal, if necessary or appropriate, requires the affirmative vote of the stockholders of a majority in voting power present if a quorum is not present, or, if a quorum is present, the affirmative vote of the holders of a majority of the votes cast.

Failure to Vote, Broker Non-Votes and Abstentions

If your shares of Limelight common stock are held in “street name” in a stock brokerage account or by another nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank, broker or other nominee. You may not vote shares of Limelight common stock held in street name by returning a proxy card directly to Limelight.

Banks, brokers or other nominees who hold shares of Limelight common stock in street name for a beneficial owner typically have the authority to vote in their discretion on “routine” proposals, even when they have not received instructions from beneficial owners. However, banks, brokers or other nominees are not allowed to exercise their voting discretion on matters that are determined to be “non-routine” without specific instructions from the beneficial owner. A “broker non-vote” is a vote that, in accordance with stock exchange rules, is not cast by a broker on a non-routine matter because the bank, broker or other nominee has not received instructions from the beneficial owner of such shares to vote on the particular proposal and the bank, broker or other nominee does not have discretionary voting power on such proposal.

Under the written rules of the NASDAQ Global Select Market (“Nasdaq”), banks, brokers or other nominees do not have discretionary authority to vote on any of the proposals to be voted upon at this annual meeting. Therefore, if you are a Limelight stockholder who holds shares in “street name” and you do not instruct your bank, broker or other nominee on how to vote your shares, your bank, broker or other nominee may not vote your shares on any of these proposals, and the resulting broker non-vote will have no effect on these proposals.

Instructions to “ABSTAIN” for each proposal to be voted upon at the annual meeting will be counted for purposes of determining the number of shares present and entitled to vote for purposes of determining a quorum. Abstentions will not be included in the vote totals for each proposal and will have no effect on the outcome of the vote on the stock issuance proposal, the ratification proposal or the adjournment proposal. If you return your signed proxy card but do not mark the boxes indicating how you wish to vote, your shares will be voted “FOR” the stock issuance proposal, “FOR” the director election proposal, “FOR” the ratification proposal and “FOR” the adjournment proposal.

Voting at the Annual Meeting

Whether or not you plan to attend the annual meeting virtually, please vote your shares. If you are a registered or “record” holder, which means your shares are registered in your name with American Stock Transfer & Trust Company, LLC, our transfer agent, you may vote in person at the annual meeting or be represented by proxy. If your shares are held in “street name,” which means your shares are held of record in an account with a bank, broker or other nominee, you must follow the instructions from your bank, broker or other nominee in order to vote. If you do not plan to attend the annual meeting or do not wish to vote at the annual meeting, you may authorize proxies to vote your shares by written proxy, by telephone or over the internet.

45

Voting by Proxy

You should vote your proxy in advance of the meeting even if you plan to attend the annual meeting. If you are a Limelight stockholder of record, a proxy card is enclosed for your use., we recommend that you promptly submit your proxy, even if you plan to attend the annual meeting virtually, using one of the following four methods:

If you vote via the Internet or by telephone, please do not return a signed proxy card.

If you hold your shares of Limelight common stock in street name (i.e., through a bank, broker or other nominee), you will find enclosed instructions from your bank, broker or other nominee that you must follow in order to vote your shares. You may authorize proxies to vote your shares by telephone or over the internet if your bank, broker or other nominee makes these methods available, as detailed on the enclosed voting instruction form. You may also return your voting instructions by signing, dating and returning the enclosed voting instruction form in the postage-paid envelope provided.

YOUR VOTE IS IMPORTANT. ACCORDINGLY, PLEASE SUBMIT YOUR PROXY PROMPTLY, BY TELEPHONE, INTERNET OR MAIL WHETHER OR NOT YOU PLAN TO ATTEND THE ANNUAL MEETING.

How Proxies are Counted

All shares represented by properly executed proxies received in time for the annual meeting will be voted at the meeting in the manner specified by the stockholders giving those proxies. Properly executed proxies that do not contain voting instructions will be voted “FOR” each of the proposals covered by this proxy statement.

Only shares affirmatively voted for the proposals, and properly executed proxies that do not contain voting instructions, will be counted as “FOR” the proposals submitted by us as described in this proxy statement. Abstentions will not be included in the vote totals for each proposal and will have no effect on the outcome of the vote on any of the proposals. Failures to vote and broker non-votes, if any, will have no effect on the outcome of any of the proposals.

Revocation of Proxies

You can change your vote or revoke your proxy at any time before your proxy is voted at the annual meeting. If you are a stockholder of record, you can do this in one of three ways:

46

A registered stockholder may revoke a proxy by any of these methods, regardless of the method used to deliver the stockholder’s previous proxy.

If you are a “beneficial holder” who holds shares of Limelight common stock in “street name,” you must contact your bank, broker or other nominee to change your vote.

Tabulation of Votes

We appointed [●] to serve as the Inspector of Election for the annual meeting. [●] will independently tabulate affirmative and negative votes and abstentions.

Solicitation of Proxies

We are soliciting proxies for the annual meeting from our stockholders. We will pay our own cost of soliciting proxies, including the cost of mailing this proxy statement, from our stockholders. In addition to solicitation by use of the mails, proxies may be solicited by each of our directors and certain members of our management team, each of whom may be deemed a participant in this solicitation, in person or by telephone or other means of communication. These persons will not receive additional compensation, but may be reimbursed for reasonable out-of-pocket expenses in connection with this solicitation.

We have retained Innisfree M&A Incorporated to provide investor response services and assist in the solicitation of proxies at a solicitation fee of up to $30,000 plus related reasonable out-of-pocket expenses. We will make arrangements with brokerage houses, custodians, nominees and fiduciaries to forward proxy solicitation materials to beneficial owners of shares held of record by them. We will also reimburse these brokerage houses, custodians, nominees and fiduciaries for their reasonable expenses incurred in forwarding the proxy materials.

Adjournments

If quorum is not present, any adjournment or postponement of the annual meeting may be made by the chairperson of the meeting or a majority in voting power of the stockholders present; provided, however, that if the adjournment is for more than thirty days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the adjourned meeting. If after the adjournment a new record date for stockholders entitled to vote is fixed for the adjourned meeting, the Limelight board shall fix a new record date for notice of such adjourned meeting and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such adjourned meeting as of the record date for notice of such adjourned meeting. If a quorum is not present at the annual meeting, or if there are not sufficient votes at the time of the annual meeting to approve the stock issuance proposal, then our stockholders may be asked to vote on a proposal to adjourn the annual meeting so as to permit the further solicitation of proxies.

47

PROPOSAL 1: STOCK ISSUANCE PROPOSAL

General

On March 6, 2022, we entered into the purchase agreement with College Parent, pursuant to which we agreed to acquire all of the issued and outstanding shares of Edgecast common stock and certain Edgecast-related businesses and assets held by each of Yahoo India Private Limited, Edgecast Digital do Brasil Ltda, and Oath (Israel) Ltd. (such acquisition of Edgecast-related businesses and assets, the “local transfers”). The purchase price consists of approximately 71.9 million shares of Limelight common stock, representing a value of approximately $300 million based on the 30-day trailing VWAP (as of March 4, 2022) of $4.1168, which includes a $30 million cash investment in Limelight by College Parent. College Parent can also receive up to an additional 12.7 million shares of Limelight common stock, representing up to an additional $100 million in value, over the period ending on the third anniversary of the closing, subject to the achievement of certain share-price targets. For more information, see “The Transaction” located elsewhere in this proxy statement.

Upon closing of the transaction, current Limelight stockholders will own approximately 65% of Limelight, or approximately 61% assuming Limelight achieves all share price targets under the purchase agreement and thus triggering the issuance of the Limelight earnout shares, and College Parent will own approximately 35% or 39%, respectively.

Nasdaq Capital Market Stockholder Approval Requirements

Limelight common stock is listed on, and Limelight is subject to the rules and regulations of Nasdaq. Rule 5635(a) of the Nasdaq rules requires stockholder approval with respect to issuances of Limelight common stock, among other instances, when the shares to be issued are being issued in connection with the acquisition of the stock or assets of another company and are equal to 20% or more of the outstanding shares of Limelight common stock before the issuance. Rule 5635(b) of the Nasdaq rules also requires stockholder approval when any issuance or potential issuance will result in a “change of control” of the issuer. Although Nasdaq has not adopted any rule on what constitutes a “change of control” for purposes of Rule 5635(b), Nasdaq has previously indicated that the acquisition of, or right to acquire, by a single investor or affiliated investor group, as little as 20% of the common stock (or securities convertible into or exercisable for common stock) or voting power of an issuer could constitute a change of control. Rule 5635(d) of the Nasdaq rules also requires stockholder approval for a transaction other than a public offering involving the sale, issuance or potential issuance by an issuer of common equity securities (or securities convertible into or exercisable for common equity securities) at a price that is less than market value of the stock if the number of equity securities to be issued is or may be equal to 20% or more of the common equity securities, or 20% or more of the voting power, outstanding before the issuance.

As described above, we are proposing to issue approximately 71.9 million shares of Limelight common stock upon closing of the transaction, and up to an additional 12.7 million shares over the period ending on the third anniversary of the closing of the transaction, pursuant to the terms of the purchase agreement. The number of shares we will issue will exceed 20% of both the voting power and the number of shares of Limelight common stock outstanding before the issuance. Accordingly, at the annual meeting, we are asking holders of shares of Limelight common stock to consider and vote on the stock issuance proposal to satisfy Nasdaq rules.

Recommendation of the Board

Stockholder approval of the stock issuance proposal is a condition to completion of the transaction pursuant to the purchase agreement. If our stockholders do not approve the stock issuance proposal,

48

we will be unable to consummate the transaction and the purchase agreement may be terminated by us or College Parent. For more information, see “The Stock Purchase Agreement—Termination of the Stock Purchase Agreement” located elsewhere in this proxy statement.

Vote Required for Approval

The stock issuance proposal will be approved if a majority of the votes cast by stockholders in person or via proxy with respect to this matter are cast in favor of the proposal. The stock issuance proposal is a “non-discretionary” or “non-routine” item, meaning that brokerage firms cannot vote shares in their discretion on behalf of a client if the client has not provided the brokerage firm voting instructions. Accordingly, if you hold your shares in “street name” and fail to instruct your broker to vote your shares for the proposal, your shares will not be counted as votes cast for the proposal and will have no effect on the outcome of the stock issuance proposal.

THE LIMELIGHT BOARD UNANIMOUSLY RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE STOCK ISSUANCE PROPOSAL. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED “FOR” THE APPROVAL OF THIS PROPOSAL.

49

THE TRANSACTION

General Description of the Transaction

On March 6, 2022, Limelight entered into the purchase agreement pursuant to which indirect, wholly-owned subsidiaries of Limelight will (i) purchase all of the issued and outstanding shares of Edgecast common stock (“Edgecast common stock”) and (ii) certain Edgecast-related businesses and assets held by each of Yahoo India Private Limited, Edgecast Digital do Brasil Ltda, and Oath (Israel) Ltd. will be transferred to wholly-owned subsidiaries of Limelight (such transactions, collectively, the “sale”). If the transaction is completed, Limelight currently anticipates issuing approximately 71.9 million shares of Limelight common stock to its indirect, wholly-owned subsidiaries, which will be transferred to College Parent (or a designated subsidiary), in connection with the transaction. The Limelight common stock to be transferred to College Parent represents a value of approximately $300 million based on the 30-day trailing VWAP (as of March 4, 2022) of $4.1168, which includes a $30 million cash investment in Limelight by College Parent (or a designated subsidiary). College Parent (or a designated subsidiary) can also receive up to an additional 12.7 million shares of Limelight representing up to an additional $100 million in consideration, over the period ending on the third anniversary of the closing of the transaction, subject to the achievement of certain share-price targets.

The purchase agreement contemplates that, prior to the closing, Edgecast and its subsidiaries will effect certain inter-company transactions (the “pre-closing restructuring”), which will result in Edgecast and its subsidiaries, Edgecast Limited, Edgecast Services Limited and Edgecast Canada ULC (together with Edgecast, each a “transferred entity,” and collectively, the “transferred entities”) owning the assets of the Edgecast business, other than certain components of the Edgecast-related business and assets held by College Parent that will be separately transferred pursuant to the purchase agreement.

We anticipate changing the name of Limelight to Edgio, Inc. prior to or at the closing. At the closing, Limelight and College Parent (and/or their designated subsidiaries) will enter into: (a) a stockholders agreement (the “stockholders agreement”) pursuant to which, among other things, Limelight will grant College Parent certain board and governance rights; (b) a registration rights agreement (the “registration rights agreement”) pursuant to which, among other things, Limelight must use commercially reasonably efforts to file with the SEC a registration statement on Form S-3 on or before (i) a 24 month lock-up period following closing, with respect to Limelight common stock issued at closing and (ii) for Limelight common stock issued in connection with a triggering event (as such term is defined in the stockholders agreement), the period ending on the later of (x) the date that is 24 months from the closing and (y) the date that is six months after the date Limelight common stock is issued to College Parent (the “relevant restricted period”); (c) one or more commercial agreements to reflect the service terms and obligations applicable to and governing certain service orders (collectively, the “commercial agreements”); (d) a domain name sublicense agreement (the “domain name sublicense agreement”) and a patent cross license agreement (the “patent cross license agreement”), each relating to the licensing of domain names and patents, respectively and (e) a transition services agreement (the “transition services agreement”) whereby College Parent will provide various services to Limelight following the closing.

Background of the Transaction

From time to time the Limelight board, together with Limelight management, has considered various strategic business initiatives intended to strengthen its business and enhance stockholder value. These have included licensing or acquiring rights to complementary technologies, or acquisitions of, or mergers with, other companies that have complementary products or technologies.

50

On May 3, 2021, Apollo announced that funds managed by affiliates of Apollo (the “Apollo Funds”) entered into an agreement to acquire Verizon Media Group for $5 billion. At the closing of the acquisition on September 1, 2021, Verizon Media Group was renamed “Yahoo” and Verizon Communications Inc. retained 10% ownership of the company.

On June 27, 2021, representatives of RBC Capital Markets, LLC (“RBC”), financial advisor to the Apollo Funds, contacted Robert Lyons, Chief Executive Officer of Limelight, to convey the Apollo Funds’ interest in exploring a potential business combination of Limelight and Edgecast. Yahoo is the parent company of Edgecast and College Parent is the ultimate parent company that controls Yahoo and Edgecast. Following this discussion, Reed Rayman, a Partner at Apollo, contacted Mr. Lyons and the parties discussed in general terms the potential advantages of such a business combination. The parties viewed these potential advantages as warranting further discussion following the exchange of certain non-public information concerning Edgecast and its business.

One June 30, 2021, Limelight entered into a joinder to an existing non-disclosure agreement, dated November 24, 2020, with Verizon and Apollo Funds to allow the parties to share non-public information in connection with a mutual evaluation of a potential business combination transaction.

On March 6, 2022, the Limelight board held a meeting, at which members of senior management and representatives of each of Goldman Sachs and Goodwin were present, to consider approval of the proposed transaction with College Parent. At the meeting, representatives of Goldman Sachs, Goodwin and senior management updated the Limelight board regarding the recent interactions with College Parent, Yahoo and Apollo Funds and the status of the definitive transaction documentation. Goldman Sachs reviewed with the Limelight board Goldman Sachs’ financial analyses of the Aggregate Consideration (as defined in Goldman Sachs’ written opinion, dated March 6, 2022 the “written opinion”) to be paid by Limelight. The representatives of Goodwin reviewed the fiduciary duties of the directors in this context and, thereafter, reviewed the terms of the proposed purchase agreement and the related documentation. Goldman Sachs then delivered to the Limelight board its oral opinion, which was subsequently confirmed by delivery of the written opinion to the effect that, as of March 6, 2022, and based upon and subject to the factors and assumptions set forth therein, the Aggregate Consideration to be paid by Limelight in the transaction pursuant to the stock purchase agreement was fair from a financial point of view to Limelight. Following discussion and consideration of the purchase agreement and the other transactions contemplated by the purchase agreement (including the factors described in the section entitled “The Transaction—Recommendation of the Limelight Board and Its Reasons for the Transaction”), the members of the Limelight board unanimously adopted resolutions (i) determining that the purchase agreement and the transactions contemplated thereby, including the sale and the primary issuance, were advisable, fair to and in the best interests of Limelight and Limelight’s stockholders and (ii) approving and adopting the purchase agreement and the transactions contemplated thereby, including the issuance of shares of Limelight common stock pursuant to the purchase agreement, including the issuance of (a) Limelight common stock in connection with the sale, (b) the primary issuance purchaser shares and (c) the Limelight earnout shares upon the occurrence of a triggering event (as such term is defined in the purchase agreement).

Also on March 6, 2022, the parties executed the purchase agreement. Prior to the opening of the U.S. stock markets on the morning of March 7, 2022, the parties issued a joint press release announcing the transaction.

Recommendation of the Limelight Board and Its Reasons for the Transaction

The Limelight board carefully reviewed and considered the proposed transaction in consultation with Limelight’s senior management and legal and financial advisors and the Limelight board (i) determined that the purchase agreement and the transactions contemplated thereby, including the sale and the

55

primary issuance, are advisable, fair to and in the best interests of Limelight and Limelight’s stockholders and (ii) approved and adopted the purchase agreement and the transactions contemplated thereby, including the issuance of shares of Limelight common stock pursuant to the purchase agreement, including the issuance of (a) Limelight common stock in connection with the sale, (b) the primary issuance purchaser shares and (c) the Limelight earnout shares upon the occurrence of a triggering event (as such term is defined in the purchase agreement). Accordingly, the Limelight board recommends that stockholders vote “FOR” the approval of the share issuance proposal at the annual meeting.

In reaching their decision to approve the stock purchase agreement, and to recommend that Limelight stockholders approve the stock issuance proposal at the annual meeting, the Limelight board considered the following positive reasons to support the purchase agreement:

56

In the course of its deliberations, the Limelight board also considered, among other things, the following negative factors:

57

The preceding discussion of the information and factors considered by the Limelight board is not, and is not intended to be, exhaustive. In light of the variety of factors considered in connection with their evaluation of the transaction and the complexity of these matters, the Limelight board did not find it practicable to, and did not, quantify or otherwise attempt to rank or assign relative weights to the various factors considered in reaching their respective determinations. In considering the factors described above and any other factors, individual members of the Limelight board may have viewed factors differently or given different weight, merit or consideration to different factors. In addition, the Limelight board did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to the ultimate determination of the Limelight board, but rather the Limelight board conducted an overall review of the factors described above, including discussions with Limelight’s senior management and legal and financial advisors.

The foregoing discussion of the reasoning of the Limelight board and certain information presented in this section is forward-looking in nature and, therefore, the information should be read in light of the factors discussed in the section entitled “Special Note About Forward-Looking Statements.” located elsewhere in this proxy statement.

Opinion of Limelight’s Financial Advisor

Goldman Sachs & Co. LLC (“Goldman Sachs”) rendered its written opinion, dated March 6, 2022 (the “Goldman Sachs opinion”) to the Limelight board that, as of March 6, 2022 and based upon and subject to the factors and assumptions set forth therein, the aggregate consideration to be paid by Limelight in the transaction pursuant to the purchase agreement was fair from a financial point of view to Limelight. The “aggregate consideration” consists of the aggregate closing consideration, as adjusted pursuant to the terms of the purchase agreement, the Limelight earnout shares and the primary issuance purchase price.

The full text of the Goldman Sachs opinion, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the Goldman Sachs opinion, is attached as Annex B. Goldman Sachs provided advisory services and its opinion for the information and assistance of the Limelight board in connection with its consideration of the transaction. The Goldman Sachs opinion is not a recommendation as to how any holder of Limelight common stock should vote with respect to the transaction, or any other matter.

58

In connection with rendering the Goldman Sachs opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

Goldman Sachs also held discussions with members of the senior managements of Limelight, Edgecast and Yahoo regarding their assessment of the strategic rationale for, and the potential benefits of, the transaction and the past and current business operations, financial condition, and future prospects of Edgecast and Limelight; reviewed the reported price and trading activity for Limelight common stock; compared certain financial information for Edgecast and certain financial and stock market information for Limelight with similar financial and stock market information for certain other companies the securities of which are publicly traded; and performed such other studies and analyses, and considered such other factors, as it deemed appropriate.

For purposes of rendering this opinion, Goldman Sachs, with Limelight’s consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, it, without assuming any responsibility for independent verification thereof. In that regard, Goldman Sachs assumed with Limelight’s consent that the forecasts, including the synergies, and the adjustment estimates were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Limelight. Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or other off-balance-sheet assets and liabilities) of Limelight, any of its subsidiaries or Edgecast and it was not furnished with any such evaluation or appraisal. Goldman Sachs assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the transaction will be obtained without any adverse effect on Limelight or Edgecast or on the expected benefits of the transaction in any way meaningful to its analysis. Goldman Sachs

59

has also assumed that the transaction will be consummated on the terms set forth in the purchase agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to its analysis.

Goldman Sachs’ opinion does not address the underlying business decision of Limelight to engage in the transaction or the relative merits of the transaction as compared to any strategic alternatives that may be available to Limelight; nor does it address any legal, regulatory, tax or accounting matters. Goldman Sachs’ opinion addresses only the fairness from a financial point of view, as of the date of the Goldman Sachs opinion, of the aggregate consideration to be paid by Limelight in the transaction pursuant to the purchase agreement. Goldman Sachs’ opinion does not express any view on, and does not address, any other term or aspect of the purchase agreement or the transaction or any term or aspect of any other agreement or instrument contemplated by the purchase agreement or entered into or amended in connection with the transaction, including the fairness of any ongoing obligations of Limelight, any allocation of the aggregate consideration, the ancillary agreements, and the fairness of the transaction to, or any consideration received in connection therewith by, the holders of any class of securities, creditors, or other constituencies of Limelight; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of Limelight, or any class of such persons in connection with the transaction, whether relative to the aggregate consideration to be paid by Limelight in the transaction pursuant to the purchase agreement or otherwise. Goldman Sachs’ opinion was necessarily based on economic, monetary market and other conditions, as in effect on, and the information made available to it as of the date of the Goldman Sachs opinion and Goldman Sachs assumed no responsibility for updating, revising or reaffirming its opinion based on circumstances, developments or events occurring after the date of the Goldman Sachs opinion. In addition, Goldman Sachs does not express any opinion as to the prices at which shares of Limelight common stock will trade at any time, as to the potential effects of volatility in the credit, financial and stock markets on Limelight, Yahoo or Edgecast or the transaction, or as to the impact of the transaction on the solvency or viability of Limelight, Yahoo or Edgecast or the ability of Limelight, Yahoo or Edgecast to pay their respective obligations when they come due. Goldman Sachs’ opinion was approved by a fairness committee of Goldman Sachs.

The following is a summary of the material financial analyses delivered by Goldman Sachs to the Limelight board in connection with rendering the Goldman Sachs opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs, nor does the order of analyses described represent relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs’ financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before March 4, 2022, the last trading day before the public announcement of the transaction, and is not necessarily indicative of current market conditions.

Illustrative Present Value of Future Share Price Analysis.

Goldman Sachs performed an illustrative analysis of the implied present value of an illustrative future value per share of Limelight common stock, based on theoretical future values, as a function of the company’s financial multiples, calculated by Goldman Sachs for the shares of Limelight common stock on a stand-alone basis and on pro forma bases giving effect to the transaction with synergies and without synergies. For this analysis, Goldman Sachs used the forecasts. Goldman Sachs first calculated the implied enterprise value, as of the end of each of fiscal years 2022 to 2024, by applying enterprise value to next twelve months (“NTM”) revenue multiples (which is referred to for the purpose of this section of this proxy statement as “EV/NTM revenue”) of 1.5x to 3.5x (in the case of the analysis on a stand-alone basis) and 2.0x to 4.0x (in the case of the analyses on a pro forma basis with the

60

synergies and without the synergies) to revenue estimates from the forecasts for each of fiscal years of 2023 to 2025. These illustrative EV/NTM revenue multiples were derived by Goldman Sachs utilizing its professional judgment and experience, and taking into account current and historical EV/NTM revenue multiples for Limelight and Akamai Technologies, Inc. (“Akamai”). Although Akamai is not directly comparable to Limelight, Akamai was chosen because it is a publicly traded company with operations that, for purposes of analysis, may be considered similar to certain operations of Limelight. Goldman Sachs then subtracted the net debt of Limelight as of the applicable fiscal year ends, as set forth in the forecasts, from such implied enterprise values to obtain implied equity values of Limelight as of such fiscal year ends. Goldman Sachs then divided these implied present equity values by the number of fully diluted shares, including the impact of any Limelight earnout shares estimated by the management of Limelight to be issued as of such fiscal year ends, as provided by management of Limelight to Goldman Sachs. Goldman Sachs then discounted these implied future equity value per share amounts as of the fiscal year ends 2022 to 2024 back to December 31, 2021 to obtain implied present equity value per share amounts for Limelight, using an illustrative discount rate of 9.3%, reflecting an estimate of Limelight’s cost of equity. Goldman Sachs derived such discount rate by application of the capital asset pricing model (“CAPM”), which requires certain company-specific inputs, including a beta for the company, as well as certain financial metrics for the United States financial markets generally. These analyses indicated ranges of illustrative implied present values of:

Illustrative Discounted Cash Flow Analysis.

Using the forecasts, including the estimates for future usage of net operating losses included in the forecasts, Goldman Sachs performed an illustrative discounted cash flow analysis on Limelight on a stand-alone basis and on a pro forma basis giving effect to the transaction with the synergies and without the synergies, to derive ranges of illustrative present values per share of Limelight common stock.

Using discount rates ranging from 8.5% to 10.0%, reflecting estimates of Limelight’s weighted average cost of capital, Goldman Sachs discounted to present value as of December 31, 2021 (i) estimates of unlevered free cash flow for Limelight for the years 2022 through 2028 as reflected in the forecasts and (ii) a range of illustrative terminal values for Limelight, which were calculated by applying exit terminal year multiples, ranging from 12.0x to 16.0x, to the last twelve month adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) for the terminal year as reflected in the forecasts (which analysis implied perpetuity growth rates ranging from 6.0% to 8.1% on a stand-alone basis). Goldman Sachs derived such discount rates by application of the CAPM, which requires certain company-specific inputs, including the company’s target capital structure weightings, the cost of long-term debt, after-tax yield on permanent excess cash, if any, future applicable marginal cash tax rate and a beta for the company, as well as certain financial metrics for the United States financial markets generally. The range of exit terminal year multiples was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account current and historical NTM Adjusted EBITDA multiples for Limelight and Akamai. Although Akamai is not directly comparable to Limelight, the company was chosen because it is a publicly traded company with operations that for purposes of analysis may be considered similar to certain operations of Limelight. Goldman Sachs derived ranges of illustrative enterprise values for Limelight by adding (i) the ranges of present values it derived above and (ii) the estimated aggregate present value of the benefits of Limelight’s net operating losses, or

61

“NOLs,” for the years 2022 through 2028, as reflected in the forecasts, which Goldman Sachs calculated by discounting the estimated values of such NOLs for such years to present value as of December 31, 2021 using a discount rate of 9.25%, reflecting an estimate of Limelight’s weighted average cost of capital. Goldman Sachs then subtracted the net debt of Limelight of $33,330,579, as of December 31, 2021, as provided by management of Limelight to Goldman Sachs, from the ranges of illustrative enterprise values to derive ranges of illustrative equity values. Goldman Sachs then divided the ranges of illustrative equity values it derived by 136,099,530 shares of Limelight common stock plus the implied dilutive effect of options and restricted stock units (“RSUs”) based on 15,124,539 RSUs and 12,221,870 options outstanding as of March 4, 2022, including the impact of any Limelight earnout shares estimated by the management of Limelight to be issued, as provided by Limelight management to Goldman Sachs, to derive ranges of illustrative present values of:

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to Limelight, Yahoo or Edgecast or the transaction.

Goldman Sachs prepared these analyses for purposes of Goldman Sachs’ providing its opinion to the Limelight board as to the fairness from a financial point of view of the aggregate consideration to be paid by Limelight in the transaction pursuant to the purchase agreement. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Limelight, Yahoo, Edgecast, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast.

The aggregate consideration to be paid by Limelight in the transaction pursuant to the purchase agreement was determined through arm’s-length negotiations between Limelight and Yahoo and was approved by the Limelight board. Goldman Sachs provided advice to Limelight during these negotiations. Goldman Sachs did not recommend any specific amount of consideration to Limelight or the Limelight board or that any specific amount of consideration constituted the only appropriate consideration for the transaction.

As described in the section entitled “Recommendation of the Limelight Board and Its Reasons for the Transaction” located elsewhere in this proxy statement, Goldman Sachs’ opinion to the Limelight board was one of many factors taken into consideration by the Limelight board in making its determination to approve the purchase agreement. The foregoing summary does not purport to be a complete description

62

of the analyses performed by Goldman Sachs in connection with the Goldman Sachs opinion and is qualified in its entirety by reference to the Goldman Sachs opinion of attached as Annex B.

Goldman Sachs and its affiliates are engaged in advisory, underwriting and financing, principal investing, sales and trading, research, investment management and other financial and non-financial activities and services for various persons and entities. Goldman Sachs and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which they co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of the Limelight, Yahoo, Edgecast and any of their respective affiliates and third parties, including Apollo Global Management, Inc. (“Apollo”) and Verizon Communications, Inc. (“Verizon”), both significant shareholders of Yahoo and their respective affiliates (collectively, the “significant shareholders”) and, as applicable, portfolio companies, or any currency or commodity that may be involved in the transaction. Goldman Sachs acted as financial advisor to Limelight in connection with, and participated in certain of the negotiations leading to, the transaction.

Goldman Sachs has provided certain financial advisory and/or underwriting services to Limelight and its affiliates from time to time for which the Investment Banking Division of Goldman Sachs has received, and may receive, compensation, including the matters set forth in Annex B of this proxy statement.

Goldman Sachs also has provided certain financial advisory and/or underwriting services to Apollo and/or its affiliates and portfolio companies from time to time for which our Investment Banking Division has received, and may receive, compensation, including the matters set forth in Annex B of this proxy statement.

Goldman Sachs also has provided certain financial advisory and/or underwriting services to Verizon and/or its affiliates from time to time for which its Investment Banking Division has received, and may receive, compensation, including the matters set forth in Annex B to this proxy statement.

During the two-year period ended March 6, 2022, Goldman Sachs has recognized compensation for financial advisory and/or underwriting services provided by its Investment Banking Division to Limelight and/or its affiliates of approximately $2,379,753. Goldman Sachs may also in the future provide financial advisory and/or underwriting services to Limelight, Yahoo, Apollo, Verizon and their respective affiliates and, as applicable, portfolio companies for which the Investment Banking Division of Goldman Sachs may receive compensation. Affiliates of Goldman Sachs also may have co-invested with Apollo and its affiliates from time to time and may have invested in limited partnership units of affiliates of Apollo from time to time and may do so in the future.

The Limelight board selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the transaction. Pursuant to that certain Letter Agreement, dated January 25, 2022, by and between Limelight and Goldman Sachs (the “engagement letter”), Limelight engaged Goldman Sachs to act as its financial advisor in connection with the transaction. The engagement letter between Limelight and Goldman Sachs provides for a transaction fee of $6,000,000 plus a discretionary amount of up to $4,000,000, $750,000 of which transaction fee became payable at announcement of the transaction, and the remainder of which is contingent upon consummation of the transaction. In addition, Limelight has agreed to reimburse Goldman Sachs for certain of its expenses, including attorneys’ fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.

Certain Unaudited Prospective Financial Information

Limelight does not, as a matter of course, make public projections as to future performance or earnings beyond the current fiscal year. Limelight generally does not make public financial projections for extended periods given, among other things, the inherent difficulty of predicting financial performance for future periods and the likelihood that the underlying assumptions and estimates may not be realized. However, included below are certain unaudited financial forecasts that, as described below, were furnished to the Limelight board in connection with discussions concerning the transaction and were considered by the Limelight board in connection with its evaluation of the transaction, and were furnished to Goldman Sachs in connection with its financial analyses and in connection with its role as financial advisor as described in the section entitled “The Transaction—Opinion of Limelight’s Financial Advisor” located elsewhere in this proxy statement.

For internal purposes and in connection with the process leading to the purchase agreement, Limelight management prepared certain unaudited prospective financial information of Limelight on a stand-alone basis for the remainder of fiscal year 2021 and fiscal years 2022 through 2028 (the “Limelight Management Limelight Projections”). The estimates of Limelight’s future financial performance set forth in the section below entitled “Summary of the Limelight Management Limelight Projections” were prepared by Limelight management based on Limelight management’s reasonable best estimates, judgments and assumptions with respect to Limelight’s future financial performance at the time such estimates were prepared. The Limelight Management Limelight Projections were provided to the Limelight board and Goldman Sachs.

In connection with the transaction with Limelight, Yahoo management prepared certain unaudited prospective financial information for Edgecast for the remainder of fiscal year 2021 and fiscal year 2022 (the “Yahoo Management Edgecast Projections”). The estimates of Edgecast future financial performance set forth in the section entitled “Certain Unaudited Prospective Financial Information—Summary of the Yahoo Management Edgecast Projections” located elsewhere in this proxy statement were prepared by Yahoo management based on Yahoo management’s reasonable best estimates, judgments and assumptions with respect to Edgecast’s future financial performance at the time such estimates were prepared. The Yahoo Management Edgecast Projections were prepared by Yahoo management in connection with the transaction and were provided to the Limelight board, Limelight management and Goldman Sachs.

In order to have projections that would cover a longer period and would reflect certain differing assumptions with respect to future financial performance, Limelight management developed certain unaudited, prospective financial information with respect to Edgecast for the remainder of fiscal year 2021 and fiscal years 2022 through 2028 (the “Limelight Management Edgecast Projections”) based on its review of the Yahoo Management Edgecast Projections, discussions with Yahoo management, materials provided by Yahoo to Limelight management, industry data, and Limelight management’s judgment. The estimates of Edgecast future financial performance set forth in the section below entitled “Summary of the Limelight Management Edgecast Projections” were prepared by Limelight management based on Limelight management’s reasonable best estimates, judgments and assumptions with respect to Edgecast’s future financial performance at the time such estimates were prepared. None of Apollo, Yahoo or College Parent reviewed, commented on, or had any input on the Limelight Management Edgecast Projections. The Limelight Management Edgecast Projections were prepared by Limelight management at the direction of the Limelight board and were provided to the Limelight board and Goldman Sachs.

Limelight management, after discussions with Apollo and Yahoo, also estimated that the projected realization of (i) cost synergies would be $26 million and $44 million for each of fiscal years 2022 and 2023, respectively, and $49 million for each of fiscal years 2024, 2025, 2026, 2027 and 2028 and (ii) capital expenditures synergies would be $2 million for fiscal year 2022 and $3 million for each of

64

fiscal years 2023, 2024, 2025, 2026, 2027 and 2028 (the “Limelight Management Synergies Projections”). Such synergies are not reflected in the Limelight Management Limelight Projections or the Limelight Management Edgecast Projections.

In addition, Limelight management prepared certain unaudited prospective financial information for the combined company for the remainder of fiscal year 2021 and for the fiscal years 2022 through 2028 by combining the Limelight Management Limelight Projections and the Limelight Management Edgecast Projections (the “Limelight Management Combined Company Projections” and together with the Limelight Management Limelight Projections, the Yahoo Management Edgecast Projections, the Limelight Management Edgecast Projections and the Limelight Management Synergies Projections and the other forward looking information summarized below, the “Financial Projections”). The Limelight Management Combined Company Projections were provided to the Limelight board and Goldman Sachs.

The Financial Projections were not prepared with a view toward public disclosure and, accordingly, do not necessarily comply with published guidelines of the SEC or established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information or generally accepted accounting principles (“GAAP”). Limelight’s independent registered public accounting firm has not compiled, examined, audited or performed any procedures with respect to the Financial Projections, and has not expressed any opinion or any other form of assurance regarding this information or its achievability. Edgecast’s independent auditor has not compiled, examined, audited or performed any procedures with respect to the Financial Projections, and has not expressed any opinion or any other form of assurance regarding this information or its achievability.

The tables below present summaries of the Financial Projections as prepared by Limelight management and, in the case of the Yahoo Management Edgecast Projections, prepared by Yahoo management, and provided by Limelight management to the Limelight board. The Financial Projections also were provided to Goldman Sachs for use and reliance by Goldman Sachs in connection with its financial analyses and in connection with its opinion to the Limelight board as described in the section entitled “The Transaction—Opinion of Limelight’s Financial Advisor” located elsewhere in this proxy statement.

The Financial Projections summarized below are included solely to provide Limelight stockholders access to financial projections that were made available to the Limelight board in connection with the proposed transaction, and are not included in this proxy statement to influence a Limelight stockholder’s decision whether to vote to approve the share issuance proposal or for any other purpose.

The Financial Projections summarized below, while presented with numerical specificity, were based on numerous variables and assumptions that necessarily involve judgments with respect to, among other things, future economic, competitive, regulatory and financial market conditions, all of which are difficult or impossible to predict and many of which are beyond Limelight’s control. The Financial Projections also reflect assumptions that are subject to change, including, but not limited to, assumptions regarding: the revenue growth rate of Limelight and Edgecast, the capital expenditures of Limelight and Edgecast remaining constant, a 21% tax rate, in the case of Limelight, the change in Net Working Capital being between (4)% and 3% of revenue through 2028, in the case of Edgecast, the change in Net Working Capital remaining (1)% of revenue, and the standalone costs of Edgecast of $7 million in 2022 and 2023 decreasing to $5 million thereafter. The Financial Projections cover multiple years, and thus, by their nature, they become subject to greater uncertainty with each successive year. Important factors that may affect actual results and the achievability of the Financial Projections include, but are not limited to: general economic conditions and disruptions in the financial, debt, capital, credit or securities markets; industry and market dynamics; the risks and uncertainties

65

described in the section entitled “Risk Factors—Risks Related to Edgecast’s Business” in this proxy statement; and those risks and uncertainties described in Limelight’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and subsequent quarterly reports on Form 10-Q and current reports on Form 8-K. See also the section entitled “Special Note About Forward-Looking Statements” located elsewhere in this proxy statement.

In addition, the Financial Projections reflect assumptions that are subject to change and are susceptible to multiple interpretations based on actual results, revised prospects for Limelight’s and/or Edgecast’s business, changes in general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated when the Financial Projections were prepared. In addition, the Financial Projections may be affected by Limelight’s ability to achieve strategic goals, objectives and targets over the applicable period. Accordingly, actual results will differ, and may differ materially, from those contained in the Financial Projections. The Financial Projections assume organic company growth without business expansions from mergers and acquisitions or alternative business or licensing models. In addition, the Financial Projections do not take into account any circumstances, transactions or events occurring after the date on which the Financial Projections were prepared and do not give effect to any changes or expenses as a result of the transaction or any effects of the transaction. There can be no assurance that the financial results in the Financial Projections will be realized, or that future actual financial results will not materially vary from those estimated in the Financial Projections.

Certain of the measures included in the Financial Projections, including adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”), are financial measures that are not calculated in accordance with GAAP. Such non-GAAP financial measures should not be viewed as a substitute for GAAP financial measures, and may be different from non-GAAP financial measures used by other companies. Furthermore, there are limitations inherent in non-GAAP financial measures, because they exclude charges and credits that are required to be included in a GAAP presentation. Accordingly, non-GAAP financial measures should be considered together with, and not as an alternative to, financial measures prepared in accordance with GAAP. Financial measures provided to a financial advisor are excluded from the SEC’s rules concerning non-GAAP financial measures and, therefore, are not subject to SEC rules regarding disclosures of non-GAAP financial measures in disclosures relating to a proposed business combination such as the transaction if the disclosure is included in a document such as this proxy statement, which would otherwise require a reconciliation of a non-GAAP financial measure to a GAAP financial measure. Reconciliations of non-GAAP financial measures were not prepared or relied upon by the Limelight board in connection with their consideration of the purchase agreement or by Goldman Sachs for purposes of its financial analyses. Accordingly, Limelight has not provided a reconciliation of every non-GAAP financial measure included in the Financial Projections.

Summary of the Limelight Management Limelight Projections

Set forth below is a summary of the Limelight Management Limelight Projections, which were based on information as prepared by Limelight management in connection with Limelight’s evaluation of the transaction. The Limelight Management Limelight Projections were presented to the Limelight board for the purposes of considering and evaluating the transaction and were approved for use by Goldman Sachs for purposes of its financial analysis and fairness opinion (summarized in the section entitled “The Transaction—Opinion of Limelight’s Financial Advisor” located elsewhere in this proxy statement).

In addition, Limelight estimates that its net debt will be $59 million as of December 31, 2022, $57 million as of December 31, 2023, and $37 million as of December 31, 2024.

Summary of the Yahoo Management Edgecast Projections

Set forth below is a summary of the Yahoo Management Edgecast Projections, which were provided by Yahoo management to Limelight management and Goldman Sachs and were not adjusted by Limelight management. The Yahoo Management Edgecast Projections were based upon certain financial, operating and commercial assumptions developed solely using the information available to Yahoo management.

67

Summary of the Limelight Management Edgecast Projections

Set forth below is a summary of the Limelight Management Edgecast Projections prepared by Limelight management. The Limelight Management Edgecast Projections were presented to the Limelight board for the purposes of considering and evaluating the transaction and were approved to be provided to Goldman Sachs for purposes of its financial analysis and fairness opinion (summarized in the section entitled “The Transaction—Opinion of Limelight’s Financial Advisor” located elsewhere in this proxy statement).

Summary of the Limelight Management Synergies Projections

Set forth below is a summary of the Limelight Management Synergies Projections prepared by Limelight management. The Limelight Management Synergies Projections were presented to the Limelight board for the purposes of considering and evaluating the transaction and were approved to be provided to Goldman Sachs for purposes of its financial analysis and fairness opinion (summarized in the section entitled “The Transaction—Opinion of Limelight’s Financial Advisor” located elsewhere in this proxy statement).

68

Summary of the Limelight Management Combined Company Projections

Set forth below is a summary of Limelight Management Combined Company Projections prepared by Limelight management, which were reviewed by the Limelight board. The Limelight Management Combined Company Projections were presented to the Limelight board for the purposes of considering and evaluating the transaction and were approved to be provided to Goldman Sachs for purposes of its financial analysis and fairness opinion (summarized in the section entitled “The Transaction—Opinion of Limelight’s Financial Advisor” located elsewhere in this proxy statement).

In addition, Limelight estimates that the combined company’s net debt will be $46 million as of December 31, 2022, $5 million as of December 31, 2023, and $(77) million as of December 31, 2024.

Reconciliation of the Limelight Management-Determined Adjusted EBITDA for Edgecast

Set forth below is reconciled to the Adjusted EBITDA for Edgecast for the year ended December 31, 2021 as calculated by Limelight management to Edgecast’s net loss for the year ended December 31, 2021 (see the section entitled “Combined Financial Statements of Edgecast” located elsewhere in this proxy statement). In connection with considering and evaluating the transaction, the Limelight board and management took into account, among other matters, Edgecast’s Adjusted EBITDA, as calculated by Limelight management.

69

The inclusion of selected elements of the Financial Projections in the tables and accompanying narrative above should not be regarded as an indication that Limelight and/or any of Limelight’s affiliates, officers, directors, advisors or other representatives consider the Financial Projections to be necessarily predictive of actual future events, and this information should not be relied upon as such. The Financial Projections were based upon certain financial, operating and commercial assumptions developed solely using the information available to Limelight management at the time the Financial Projections were created. None of Limelight and/or its affiliates, officers, directors, advisors or other representatives gives any Limelight stockholder or any other person any assurance that actual results will not differ materially from the Financial Projections and, except as otherwise required by law, Limelight and/or its affiliates, officers, directors, advisors or other representatives undertake no obligation to update or otherwise revise or reconcile the Financial Projections to reflect circumstances existing after the date on which the Financial Projections were prepared or to reflect the occurrence of future events, even in the event that any or all of the assumptions and estimates underlying the Financial Projections are shown to be in error. Limelight has made no representation to College Parent, Yahoo or Apollo concerning the Financial Projections in the purchase agreement or otherwise.

In light of the foregoing factors and the uncertainties inherent in the Financial Projections, Limelight stockholders are cautioned not to place undue, if any, reliance on such Financial Projections.

Interests of Limelight’s Directors and Executive Officers in the Transaction

In considering the recommendation of the Limelight board to vote “FOR” the stock issuance proposal, you should be aware that certain members of the Limelight board and certain of Limelight’s executive officers may have interests in the transaction that may be in addition to, or different from, your interests as a Limelight stockholder. These interests may create the appearance of conflicts of interest. The Limelight board was aware of these potential conflicts of interest during its deliberations on the merits of the transaction and in making its decision to approve the purchase agreement and the issuance of Limelight common stock to College Parent. These interests include the appointment of certain directors to competitors of Edgecast.

Effective as of closing of the transaction, the Limelight board will expand from its current size of eight members to nine members. Two members of the Limelight board prior to the transaction, Jefferey T. Fisher and Marc Debevoise, will resign upon the closing, and, pursuant to the stockholders agreement, three new members designated by College Parent will be appointed to the Limelight board at closing.

The transaction will not constitute a “change in control” for purposes of our currently outstanding equity-based awards and current executive severance agreements and we do not anticipate any payments, accelerated vesting or benefit enhancements to be triggered for our executive officers by the transaction.

Accounting Treatment

Limelight and Edgecast prepare their financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The transaction will be accounted for in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 805, Business Combinations, with Limelight being considered the accounting acquiror. Accordingly, Limelight will measure the assets acquired and liabilities assumed of Edgecast based on their estimated fair values as of the closing date of the transaction, with any excess aggregate closing consideration being allocated to goodwill. For more information, see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information of Limelight and Edgecast” located elsewhere in this proxy statement.

70

No Appraisal Rights

Limelight’s stockholders are not entitled to appraisal or dissenters’ rights in connection with the transaction or any of the other transactions contemplated by the purchase agreement.

Material United States Federal Income Tax Consequences of the Transaction

Limelight stockholders will not recognize any gain or loss as a result of the transaction related to their ownership of Limelight common stock. Accordingly, there are no material U.S. federal income tax consequences to you as a result of the transaction.

Regulatory Approvals Required for the Transaction

We and College Parent have agreed to use each of our reasonable best efforts to obtain all governmental and regulatory clearances and approvals required to complete the transactions contemplated by the purchase agreement, including our reasonable best efforts to: (i) resolve such objections, if any, as may be asserted by any governmental authority with respect to the transactions contemplated by the purchase agreement, provided, that neither us nor College Parent shall be under any obligation to: (a) litigate or contest any administrative or judicial action or proceeding or any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, or (b) make proposals, execute or carry out agreements or submit to orders providing for (1) the sale, divestiture or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Limelight, any of its affiliates or Edgecast, or the holding separate of shares of capital stock of Edgecast, (2) the imposition of any limitation on the ability of Limelight or any of its affiliates to freely conduct their business or own such assets or to acquire, hold or exercise full rights of ownership of shares of capital stock of Edgecast, or (3) any modification or waiver of the terms and conditions of the purchase agreement, (c) otherwise agree to any course of conduct (or refrain from taking any action) with respect to, any assets, rights, product lines, businesses, properties, divisions or operations, or, in each case, any interests therein, of Limelight or such affiliates, or the business of Edgecast; and (ii) file or cause to be filed, as promptly as practicable, but in any event no later than ten Business Days after the date of the Purchase Agreement, notifications under the United States Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”).

Under the HSR Act, certain transactions, including the transaction, may not be completed until notifications have been given and information furnished to the Antitrust Division of the Department of Justice (“Antitrust Division”) and the Federal Trade Commission (“FTC”) and all statutory waiting period requirements have been satisfied. We and College Parent filed (or caused to be filed) the Notification and Report Forms with the Antitrust Division and the FTC on March 18, 2022. Filing an HSR Notification and Report Form initiated a 30-day waiting period, during which the parties were not permitted to close the acquisition. The relevant waiting period under the HSR Act expired at 11:59 p.m. EST on April 18, 2022 and satisfies one of the conditions to the completion of the transaction.

At any time before or after the completion of the transaction, and notwithstanding the expiration or termination of the waiting period under the HSR Act, the FTC, Antitrust Division, any U.S. state or any other governmental authority could take action under the antitrust laws as it deems necessary or desirable in the public interest. Such action could include seeking to enjoin the completion of the transaction or seeking divestiture of substantial assets of the parties. Private parties may also seek to take legal action under the antitrust laws under certain circumstances. While there can be no assurance that a challenge to the transaction on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful, we do not expect any regulatory authority, state or private party to take legal action under the antitrust laws.

Limelight is not aware of any other material regulatory approvals or actions that are required for completion of the transaction that have not been obtained. It is presently contemplated that if any such

71

additional regulatory approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

Nasdaq Listing of Limelight Common Stock

We have agreed to cause the shares of Limelight common stock to be issued in connection with the transaction to be approved for listing on Nasdaq.

72

THE STOCK PURCHASE AGREEMENT

The following is a summary of the material provisions of the purchase agreement, a copy of which is attached as Annex A to this proxy statement and is incorporated into this proxy statement by reference. We urge you to carefully read this entire proxy statement, including the annexes and the other documents to which we have referred you. You should also review the section titled “Where You Can Find Additional Information and Incorporation of Certain Documents by Reference.”

The purchase agreement has been included to provide you with information regarding its terms, and we recommend that you read it in its entirety. The purchase agreement is a contractual document that establishes and governs the legal relations between the parties with respect to the transaction, the other agreements contemplated by the purchase agreement, and the transactions contemplated by the purchase agreement.

The purchase agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of the purchase agreement or other specific dates specified in the purchase agreement. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract between the respective parties and are subject to representations, warranties, covenants and agreements contained in the purchase agreement, which were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to the purchase agreement, may be subject to limitations agreed upon by the contracting parties (including being qualified by a confidential disclosure schedule made for the purposes of allocating contractual risk between the parties to the purchase agreement instead of establishing these matters as facts), and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors, security holders, or securities laws. Investors and security holders are not third-party beneficiaries under the purchase agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the purchase agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the purchase agreement, which subsequent information may or may not be fully reflected in Limelight’s public disclosures.

The representations and warranties in the purchase agreement and the description of them in this proxy statement should not be read alone but instead should be read in conjunction with the other information contained in the reports, statements and filings Limelight publicly files with the SEC. Such information can be found elsewhere in this proxy statement and in the public filings Limelight makes with the SEC, as described in the section titled “Where You Can Find Additional Information and Incorporation of Certain Documents by Reference.”

Structure of the Transaction

Upon the terms and subject to the conditions set forth in the purchase agreement, at the closing, Limelight will cause its indirect, wholly-owned subsidiary to (i) purchase all of the right, title and interest to the outstanding shares of Edgecast common stock and (ii) acquire certain Edgecast-related businesses and assets from College Parent or its applicable subsidiary. Additionally, Limelight will, prior to the closing, issue a number of shares of Limelight common stock to its indirect, wholly-owned subsidiary, which will sell those shares of Limelight common stock to College Parent in exchange for the primary issuance purchase price.

Closing of the Transaction

The closing will take place remotely by conference call and electronic exchange and delivery of signatures and documents, on the second business day following the satisfaction or waiver of the

73

conditions to closing described below under “Conditions to the Completion of the Transaction” (other than those conditions that by their nature are to be satisfied, or waived, on the date of the closing, but subject to the satisfaction or waiver of those conditions) or at such other place, time or date as may be mutually agreed upon in writing by Limelight and College Parent.

Effect of the Closing

Pursuant and subject to the terms and conditions set forth in the purchase agreement, at the closing, among other things:

Transaction Consideration

Pursuant and subject to the terms and conditions set forth in the purchase agreement, at the closing Limelight will issue to its indirect, wholly-owned subsidiary, and its indirect, wholly-owned subsidiary will transfer to College Parent, (i) in exchange for the Edgecast common stock and in consideration of the consummation of the local transfers by College Parent, $270,000,000 worth of its common stock and (ii) in exchange for a one-time payment by College Parent of $30,000,000, an additional $30,000,000 worth of Limelight common stock, in each case at the share price of $4.1168 (which is the 30-day trailing VWAP as of March 4, 2022). In the event that the sale price of Limelight common stock exceeds certain thresholds during the period beginning on March 6, 2022 and ending on the third anniversary of the closing of the transaction, Limelight will be required to issue up to an additional $100,000,000 of Limelight common stock at certain trigger prices for delivery by its indirect, wholly-owned subsidiary to College Parent in order to satisfy earnout obligations pursuant to the purchase agreement.

Treatment of Long-Term Incentive and Retention Awards

Pursuant to the purchase agreement, College Parent shall retain all liabilities in respect of each long-term cash or equity-based incentive (each an “incentive award”) or retention award granted to any transferred business employee (as defined in the purchase agreement) that is outstanding as of closing. Each such incentive award will be treated as though the transferred business employee is involuntarily terminated by College Parent without cause (or as a result of retirement, as applicable) upon the closing with respect to the accelerated vesting provisions of such award.

With respect to the portions of certain of the incentive awards that are forfeited at the closing under the terms of such awards, Limelight will grant to each transferred business employee who previously held such an award a replacement long-term cash award (each a “replacement award”). Each replacement award will be subject to the same vesting (including accelerated vesting on termination of employment), payment and forfeiture provisions as applied to the corresponding forfeited incentive award. If a replacement award is earned by a transferred business employee in accordance with the

74

terms of such replacement award, Limelight shall pay the applicable cash amount to such transferred business employee and College Parent will reimburse Limelight for such payment promptly, but in any event no later than ten business days following notice thereof from Limelight. With respect to any annual bonus that is accrued by College Parent with respect to a transferred business employee for the portion of the 2022 calendar year ending on the date of the closing, if such transferred business employee remains employed with Limelight (or its applicable subsidiary) through December 31, 2022, Limelight (or its applicable subsidiary) will pay the amount of such accrued annual bonus to such transferred business employee following December 31, 2022 concurrently when Limelight otherwise makes annual bonus payments to its employees, and College Parent will reimburse Limelight for such payment promptly, but in any event no later than ten business days following notice thereof from Limelight.

Representations and Warranties

The purchase agreement contains representations and warranties made by Limelight to College Parent, on the one hand, and by Edgecast Inc., Edgecast Limited, Edgecast Services Limited and Edgecast Canada ULC and College Parent to Limelight, on the other hand. Such representations and warranties (i) were made solely for the benefit of the parties, (ii) are subject to limitations agreed upon by the parties, (iii) are not intended to be treated as categorical statements of fact, but rather as a way of allocating contractual risk among the parties, (iv) may be subject to standards of materiality applicable to the parties that differ from what might be viewed as material to stockholders, (v) are qualified by information in confidential disclosure schedules delivered to Limelight by College Parent, on the one hand, and College Parent and the transferred entities to Limelight, on the other hand, concurrently with the execution and delivery of the purchase agreement, which contain information that modify, qualify and create exceptions to the representations and warranties set forth in the purchase agreement and (vi) were made only as of the date of the purchase agreement or such other date or dates as may be specified in the purchase agreement. Accordingly, investors and others should not rely on the representations and warranties, or any descriptions thereof, as characterizations of the actual state of facts or condition of Limelight, College Parent, the transferred entities or any of their respective subsidiaries or affiliates.

College Parent’s representations and warranties relate to, among other things:

The transferred entities’ representations and warranties relate to, among other things:

75

Limelight’s representations and warranties relate to, among other things:

76

Many of the representations and warranties in the purchase agreement are qualified by a “materiality” or “material adverse effect” standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct, individually or in the aggregate, would, as the case may be, be material or have a material adverse effect). Please refer to the definitions of “seller material adverse effect”, “business material adverse effect” and “purchaser material adverse effect” in the purchase agreement for the full description of the definitions of “material adverse effect” applicable in the purchase agreement.

Conduct of Business Prior to the Completion of the Transaction

Each of Limelight and the transferred entities has undertaken certain covenants in the purchase agreement restricting the conduct of their respective businesses between the date of the purchase agreement and the closing. In general, each of the Limelight and the transferred entities has agreed to, and to cause our and their respective subsidiaries to, carry on their respective businesses in the ordinary course of business and to use reasonable best efforts to preserve intact its business relationships with material customers, suppliers, distributors, lessors and others having material business dealings with such parties. However, each of the transferred entities and Limelight may deviate from the ordinary course covenants, if, among other things, after reasonable prior consultation with the other party, in order to take reasonable measures to comply with any law or order issued by a governmental entity in connection with SARS-CoV-2 or COVID-19, and any evolutions or mutations thereof or related or associated epidemics, pandemic or disease outbreaks.

Each of Limelight and the transferred entities has also agreed to various specific restrictions relating to the conduct of its business, including with respect to the below (subject in each case to certain exceptions, including those specified below or in the purchase agreement or disclosed in the confidential disclosure schedules provided to the other party).

Non-Competition

College Parent has agreed that neither it or nor its affiliates will permit, cause or encourage for 36 months following the date of the closing, engage or actively prepare to engage in the business, subject to certain exceptions specified in the purchase agreement.

Subject to the ability of the Limelight board to effect a recommendation change (as defined in the purchase agreement), Limelight has agreed to use reasonable best efforts to solicit from the holders of Limelight common stock proxies in favor of the approval of issuances of Limelight common stock contemplated by the purchase agreement.

Efforts to Complete the Transactions

Limelight and College Parent have agreed to, and have agreed to cause their respective subsidiaries to, use reasonable best efforts to take all actions and do all things necessary, proper or advisable under any applicable laws to consummate and make effective in an expeditious manner the transactions contemplated by the purchase agreement, including (i) the preparation and filing of all forms, registrations and notices required to be filed to consummate the transactions contemplated by the purchase agreement and (ii) the obtainment of the regulatory approvals as discussed in this document under the heading “The Transaction—Regulatory Approvals Required for the Transaction” located elsewhere in this proxy statement.

Change in Limelight Board Recommendation

Limelight has agreed under the purchase agreement to not, through an action of the Limelight board, (i) withdraw, change, amend, modify or qualify or publicly propose to withdraw, change, amend, modify or qualify, in a manner adverse to College Parent or Edgecast, its recommendation to Limelight stockholders to vote in favor of the approval of the issuances of Limelight common stock contemplated by the purchase agreement (the “purchaser board recommendation”), (ii) fail to include the purchaser board recommendation in this proxy statement, (iii) recommend the approval or adoption of, or approve or adopt, or publicly propose to recommend, approve or adopt, any acquisition proposal (as defined in the purchase agreement), (iv) fail to recommend, in a Solicitation/Recommendation Statement on Schedule 14D-9, against any acquisition proposal subject to Regulation 14D under the Exchange Act within ten business days after commencement of such acquisition proposal, (v) following the date of receipt of any acquisition proposal or any material modification thereto is first made public, sent or

80

given to the Limelight stockholders, fail to issue a press release that expressly reaffirms the purchaser board recommendation within two business days following a written request to do so from College Parent, or (vi) publicly propose to do any of the foregoing.

The purchase agreement provides that if the Limelight board reasonably determines in good faith, after consultation with outside counsel, that failure to do so would be inconsistent with its fiduciary obligations under applicable law, the Limelight board may, solely in connection with a superior proposal (as defined in the purchase agreement) or in response to an intervening event (as defined in the purchase agreement), prior to the receipt of Limelight stockholders’ approval of the stock issuance proposal (“Limelight stockholder approval”), make a recommendation change if it (A) gives Edgecast at least four business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action and (B) at the end of such notice period, takes into account any amendment or modification to the purchase agreement proposed by College Parent and reasonably determines in good faith, after consultation with outside counsel, that the failure to make a recommendation change or, to the extent permitted, terminate the purchase agreement, would be inconsistent with its fiduciary obligations under applicable law.

Acquisition Proposals

Limelight and College Parent have agreed that they will not authorize or permit any of their respective affiliates or representatives to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any acquisition proposal, (ii) engage or participate in any negotiations with any person concerning any acquisition proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with any person relating to any acquisition proposal or (iv) unless the purchase agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement.

Notwithstanding the foregoing, if after the purchase agreement and prior to the receipt of Limelight stockholder approval, Limelight receives a bona fide written acquisition proposal not solicited in violation (other than de minimis violations) of the applicable terms of the purchase agreement, Limelight and its affiliates and representatives may furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the acquisition proposal and Limelight’s representatives if the Limelight board determines in good faith after consultation with, and taking into account the advice of, its outside legal counsel that the failure to take such actions would be inconsistent with its fiduciary duties under applicable law.

Directors and Officers Indemnification, Exculpation and Insurance

The purchase agreement requires Limelight, for a period of six years following the closing, to indemnify, defend and hold harmless each person who prior to the closing is or was a current or former director, manager, officer or employee of a transferred entity, or who at the request of College Parent or any of its affiliates served prior to the closing as a director, officer, member, manager, employee, trustee or fiduciary in connection with the business from liability for or in connection with acts or omissions occurring to any time prior to or on date of the closing (the “closing date”) to the same extent as such indemnified parties were indemnified as of the date of the purchase agreement under the organizational documents of College Parent or any of its subsidiaries or any indemnification agreements in existence as of the date of the purchase agreement. The purchase agreement also requires College Parent to purchase and maintain for six years following the closing date run off coverage for the indemnified persons in an amount not less than the existing coverage and with terms

81

no less favorable to such persons than the coverage presently maintained by College Parent (the “d&o tail policy”). Limelight’s liability to all indemnified persons described in the foregoing will be limited to any recovery under the d&o tail policy.

Officers and Directors Following Closing

Pursuant to the stockholders agreement (as defined in this document under the heading “Other Agreements related to the Transaction—Stockholders Agreement” located elsewhere in this proxy statement), up to three new members designated by College Parent will be appointed to the Limelight board at the closing. See “Other Agreements related to the Transaction—Stockholders Agreement” located elsewhere in this proxy statement, for more information about the stockholders agreement and College Parent’s right to appoint certain designees to the Limelight board.
