PART 1

Overview

References herein to “we”, “us” or “our” refer to Marchex, Inc. and its wholly-owned subsidiaries unless the context specifically states or implies otherwise.

Marchex is a mobile and call advertising technology company. We provide products and services for businesses of all sizes that depend on consumer calls to drive sales. Our technology platform delivers performance-based, pay-for-call advertising across numerous mobile and online publishers to connect millions of high-intent consumers with businesses over the phone. Our call analytics technology facilitates call quality, analyzes calls in real time and measures the outcomes of calls to close the loop between digital marketing and offline transactions. We help large national brands and small-and medium-sized businesses (“SMBs”) facilitate efficient and cost-effective marketing campaigns to drive calls and customer leads to their business. With our Archeo division, we provide a performance-based pay-per-click advertising service that connects advertisers with consumers across our owned and operated web sites as well as third party web sites and we also sell domain names.

Our technology-based products and services enable our customers to connect with consumers across leading third-party mobile and online channels, as well as our proprietary network of locally-focused web sites. We have direct relationships with large national advertisers and advertising agencies which utilize our products and services to plan, execute and measure their call-focused advertising campaigns. We also provide private-label performance marketing solutions for SMBs through a network of large reseller partners, which include Yellow Pages publishers, media and telecommunications companies and vertical marketing service providers. We enable these partners to sell pay-for-call advertising, call-analytics, search engine marketing and other digital marketing services to their millions of small business customers. We execute these campaigns for them using our technology. Our primary products offerings are:

In addition to our call-driven business, we operate the Archeo Domains Marketplace, which enables the buying, selling and development of premium domain names, and includes more than 200,000 of our owned and operated websites. Our portfolio of websites contains more than 75,000 U.S. ZIP code sites, including 90210.com and covering ZIP code areas nationwide. The Archeo domain marketplace also consists of other locally-focused sites such as Yellow.com, OpenList.com and geo-targeted sites. We monetize this portfolio via pay-per-click and banner advertising and also make these domains available for sale to third parties.

We generate two categories of revenue. Call-driven revenue consists of payments from advertisers for pay-for-call marketing services and for use of our Call Analytics technology. Call-driven revenue also consists of payments from our reseller partners for use of our technology platform and marketing services, which they offer to their small business customers, as well as payments from advertisers for cost-per-action services. Archeo revenue includes revenue generated from advertisements on our network of owned and operated websites and third-party distribution, as well as from the sale of domain names in our domain marketplace. During the years ended December 31, 2011, 2012 and 2013, call-driven revenue accounted for approximately 73%, 84%, and 89% of total revenues, respectively. We operate primarily in domestic markets. For detail on revenue by geographical area for the three most recent fiscal years, see Note 13. Segment Reporting and Geographic Information of the notes to our consolidated financial statements.

Industry Overview

Calls are critical for businesses to drive sales. For businesses of all sizes, in-bound phones calls are a key source of new customer leads and increased revenue. We believe consumers that call businesses directly typically have higher purchase intent and are more likely to make a purchase or become a customer. According to BIA/Kelsey Local Commerce Monitor (LCM) survey in 2012, 61.3% of advertisers believe that in-bound calls from prospective customers are the single most important type of lead. Calls are particularly relevant in high-value

categories, such as professional services, financial services, automotive and travel, where transaction values are large, complex or require additional information prior to completion. Calls are also important for local businesses that set appointments or sell products and services over the phone. According to 2012 data from BIA/Kelsey, advertisers in the U.S. spent $68 billion to drive telephone leads. Historically, the majority of this advertising has been spent on traditional media such as television, newspapers and directories. Now with the mass adoption of mobile, both large and small advertisers are increasingly seeking new marketing channels that allow them to connect with consumers over the phone.

Mobile search and calls from search are growing rapidly. Today we are witnessing an evolution in consumer behavior as Internet-enabled mobile devices proliferate and media consumption shifts to mobile devices. This trend is increasingly evident in the way consumers research products and services and connect with businesses when they are ready to make a purchase decision. BIA/Kelsey estimates that consumers conducted over 30 billion mobile searches in 2013, and that the number of mobile searches will exceed searches on desktop computers by 2016. Given the nature of mobile devices and embedded technology in mobile phones, consumers want and expect to be able to directly call businesses they are researching on mobile devices. According to a 2013 study by Google/Ipsos, over 70% of mobile search users have used a click-to-call feature to connect with a business directly from their mobile devices. BIA /Kelsey estimates that the total number of calls initiated from searches on mobile devices will increase from 15 billion in 2013 to 50 billion by 2015.

Ad budgets are shifting to performance-based models. As businesses have expanded their marketing through digital channels, they have increasingly turned to performance-based advertising formats in which they are only charged when a desired outcome is reached. Performance-based advertising models provide advertisers with greater transparency into their advertising spend and the ability to accurately measure results and return on investment. Over time, the online advertising market has experienced a dramatic shift from CPM-based banner and display advertisements to cost-per-click search advertising and other forms of performance marketing. According to the Interactive Advertising Bureau, performance-based formats accounted for only 7% of the $5 billion online advertising market in 1999, but grew to over 65% of the $40 billion market in 2013.

Calls are becoming the currency of mobile advertising. In 2013, the global mobile advertising market was $15 billion and is expected to grow to $52 billion by 2017, according to IDC. As the mobile advertising market matures, we believe advertisers will increasingly utilize performance based advertising formats available on mobile devices, as they did on desktop. Further, we believe the demand for businesses to connect with consumers over the phone combined with the inherent functionality and technical capabilities of mobile devices will result in calls becoming a primary measurement unit/format for mobile advertising, As advertisers continue to shift their budgets to accommodate for the growth of mobile and online channels, we believe the market for call-driven advertising will grow even more.

Understanding calls is highly complex. Unlike clicks, impressions and other actions that are tracked and measured in digital format, calls take place offline and require unique technical capabilities and expertise to accurately measure and analyze. To realize the full benefit of call-based marketing, advertisers need technology that allows them to capture and analyze attributes of a call before, during and after the call is completed. This technology helps them properly measure return on investment (“ROI”) and optimize their marketing campaigns across media channels. For example, advertisers must be able to dynamically track the source of a call back to the media channels and advertisements that influenced the consumer to make the call. Once a call is initiated, technology is required to understand what is happening on a call in real-time, to record calls, and to block unwanted or spam calls. For advertisers with call center operations, calls are often tracked and routed through interactive voice response (“IVR”) phone systems and integrated with customer relationship management (“CRM”) applications and back-office systems to measure transactions and return on investment. Successful marketing analytics for calls requires expertise from multiple disciplines, including digital advertising, communications infrastructure, voice and speech recognition expertise, and marketing software.

Our Competitive Strengths

Focus on calls. We were early to realize the value of calls and the importance that mobile devices would play in advertising. Over the past several years, we have shifted the focus of our company to address the large opportunity for mobile performance-based advertising focused on calls. As a pioneer in the category, we have developed a unique business model that delivers measurable return on investment to both large national advertisers and local small businesses. Our technology platform and call analytics technology and products are specifically designed to address the unique challenges associated with closing the loop between digital marketing and phone calls. Working closely with our customers, we have innovated in call-based technology, creating specific solutions to address common needs and wants among both SMBs and large advertisers. We believe we are unique with our call-focused approach to technology developments and marketing solutions, providing a competitive advantage as mobile advertising grows and advertising budgets shift towards performance-based formats.

Proprietary call analytics technology. Our call analytics technology and solutions are designed specifically to analyze and measure the performance of advertising and media spending that results in calls to businesses. The technology and solutions further help advertisers optimize their overall marketing strategies and specific campaigns by gaining insights into the different factors that can drive conversions. Our advertisers are able to benefit from increased intelligence about their specific media placement decisions and investments with dynamically driven data and information that capture and evaluate the originating media channel, advertisement, keyword or creative that drove the consumer to make the call. As a result, our technology helps advertisers understand the most effective use of advertising resources and helps to optimize their marketing spend across campaigns and distribution sources. We provide varying levels of integration with customers to enhance their information review and analysis. Our technology scales for larger customers to provide greater access and transparency on significant volumes of call leads, including with assisting the understanding of call outcomes and quality of customer experience. This integration may take the form of working with CRM platforms or customer-specific systems, with the purpose of improving each customer’s understanding of the analytics within their organization. On the technology back end of these solutions are proprietary methods and features that allow for the smoother functioning and increased efficiencies in presenting the most potentially promising leads. We are always working to create appropriate and relevant filters to improve our customer experience. For example, our Clean Call technology blocks many unwanted, unintended, misdirected or spam calls from reaching our advertiser customers, reducing time and cost wasted on unproductive calls. Our focus on features that promote ease and efficiency of use for advertisers is aligned with improving their understanding of the quality and efficiency of the sources they have deployed to drive customer acquisition, including which sources may or may not be desirable or cost-effective. In each case, they may be able to better measure the performance of their advertisement investments across their spend mobile, online and offline ad campaigns.

Transparent, performance-based model. We have developed a unique, pay-for-call business model that aligns our interests with those of our advertising customers and our publishing partners. We work closely with each customer to define a quality call for their business, and then only charge our customers, on a per call basis. As a result, we are able to deliver qualified leads that provide a measurable return on investment for our advertisers. We typically pay our publishing partners a percentage of the revenue we generate from advertisements on their properties. Through our Call Analytics, we have a deep understanding of which publishers, devices, ad formats, keywords and ad creatives drive call conversion for specific advertising verticals. This allows us to help optimize the placements of advertisements across our network to maximize the number of calls for our advertisers and revenue for our partners. As a result, advertisers utilize us to place ads on their behalf and our partners believe in us that we will only deliver ads on their properties to help generate revenue for them.

Scalable technology platform and business model. We have developed our technology platform to address the large advertisers, while also being able to support a large number of small local business advertisers. Our platform currently supports over 100,000 unique advertiser accounts, and in aggregate manages hundreds of millions of dollars in advertising spend across various digital channels. We leverage our relationships with

4

Table of Contents

Yellow Pages providers and vertical market service providers to efficiently re-sell our solutions to their small businesses customers, adding scale and data to our platform, which provides us with recurring revenues with minimal associated sales costs. We have deployed a direct sales model to acquire and service large advertisers and also have been successful at deepening our relationships with existing advertiser clients over time to capture a greater share of their advertising budgets.

Strategy

Our Strategy

To take advantage of the shift to performance-based models in marketing, key elements of our strategy include:

Building and Expanding Relationships with Advertising Agencies. Advertising agencies are influential in determining how large national advertisers allocate their advertising budgets. We believe building deep relationships with leading global advertising agencies and creating awareness within these agencies about the benefits of our offerings is an important step in attracting new large advertising customers. We plan to expand our agency relations efforts and hire personnel with strong existing relationships with advertising agencies.

Innovating on Our Mobile Performance Advertising. We plan to continue to expand our range of call-based advertising product capabilities by offering innovative performance-based products such as pay-for-call advertising, along with the supporting analytics including number provisioning, call tracking, call mining, keyword-level tracking and other products as part of our owned, end-to-end, call-based advertising solutions. We are also focused on growing our base of call distribution by bringing in new sources of the rapidly growing mobile advertising market as well as other online and offline sources of distribution.

Innovating on Our Products for Small Businesses. We plan to build and integrate new products into our marketing products for small businesses. This includes, (1) launching new performance-based small business solutions like pay-for-call advertising enhancements; (2) integrating more options for small businesses to acquire new customers over the phone, such as enhanced local ad-targeting capabilities that will enable us to consistently improve the matching of our small advertisers with our sources of call supply; (3) introducing products that enable small businesses to better cultivate relationships with existing customers; and (4) adding additional features and functionality to our web sites that connect consumers with small businesses and provide additional monetization capabilities. We believe these new products will increase our cross-sell opportunities, enable us to continue to grow our advertiser base, unlock more budget from our existing advertisers, enable us to attract new reseller partnerships and deliver better performance to our existing partners.

Supporting the Number of Advertisers Using Our Products and Services. We plan to continue to provide a consistently high level of service and support to our advertisers and we will continue to help them achieve their return on investment goals. We are focused on continuing to grow our advertiser base through our direct sales and marketing efforts, including strategic sales, inside sales, online acquisition initiatives and additional partnerships with large local advertiser reseller partners.

Developing New Markets including International Expansion. We intend to analyze opportunities and may seek to expand our technology-based products into new business areas or geographic markets where our services can be replicated on a cost-effective basis, or where the creation or development of a product or service may be appropriate. We anticipate utilizing various strategies to enter new markets, including: developing strategic relationships; acquiring products that address a new category or opportunity; and creating joint venture relationships and internal initiatives where existing services can be extended internationally.

Pursuing Selective Acquisition Opportunities. We may pursue select acquisition opportunities and will apply rigorous evaluation criteria to any acquisitions we may pursue in order to enhance our strategic position, strengthen our financial profile, augment our points of defensibility and increase shareholder value. We will focus on acquisition opportunities that represent a combination of the following characteristics:

Our Distribution Network

We have built a broad distribution network for our pay-for-call and pay-per-click advertising services that includes hundreds of mobile sources, search engines and applications, directories, third party vertical and branded web sites, our proprietary web site traffic sources through our Archeo division, which are comprised of our owned and operated web sites, and offline sources.

Syndicated Distribution:

Through our call advertising services, our local leads, pay-per-click advertising services, and search marketing services, we distribute advertisements from our tens of thousands of advertisers, as well as from our reseller partners’ advertisers, through hundreds of call-ready media and traffic sources, including mobile sources, search engines and directories, web sites and our proprietary web site traffic sources.

Our Syndicated Distribution partners include:

Payment arrangements with our distribution partners are often subject to minimum payment amounts per phone call or click-through. Other payment structures that we may use to a lesser degree include:

Table of Contents

Proprietary Web Site Traffic Sources:

We believe our proprietary web site traffic through our Archeo division is a source of local information online and is a source of click-throughs. It includes more than 200,000 web sites focused on helping users make informed decisions about products and services, including where to get local products and services.

The more than 200,000 owned and operated web sites in the network include more than 75,000 U.S. ZIP code sites, including 98102.com and 90210.com, covering ZIP code areas nationwide, as well as tens of thousands of other locally-focused sites such as Yellow.com, OpenList.com and geo-targeted sites. Traffic to our proprietary web sites is primarily monetized with pay-per-click listings that are relevant to the web sites, as well as other forms of advertising, including impression-based advertising.

Sales, Marketing & Business Development

Our sales department focuses on adding new advertisers to our business, while our business development and partnership department focuses on adding new reseller partnerships, selectively adding new distribution partnerships and servicing existing partnerships. Our marketing department focuses on promoting our services through online customer acquisition, affiliate relationships, press coverage, strategic marketing campaigns and industry exposure. Advertising and promotion of our services is broken into the following main categories:

We intend to continue our strategy of growing our advertiser base through sales and marketing programs while being as efficient as possible in terms of our marketing and advertising costs. We continually evaluate our marketing and advertising strategies to maximize the effectiveness of our programs and their return on investment.

Information Technology and Systems

We have a proprietary technology platform for the purposes of managing and delivering call and click-based advertising products and services to our partners. We also combine third party licenses and hardware to create an operating environment for delivering high quality products and services, with such features as automated online

7

Table of Contents

account creation and management process for advertisers, real-time customer support with both interactive and online reporting for customers and partners. We employ commercially available technologies and products distributed by various companies, including Cisco, Dell, Oracle, Intel, AMD, Microsoft, IBM, Nuance and Veritas. We also utilize public domain software such as Apache, Linux, MySQL, PostgreSQL, Java, Scala and Tomcat.

Our technology platform is compatible with the systems used by our distribution partners, enabling us to deliver call and click-based advertising products and services through mobile, online and offline sources in rapid response to user queries made through such partners at scale. We continue to build and innovate additional functionality to attempt to meet the quickly evolving demands of the marketplace. We devote significant financial and human resources to improving our advertiser and partner experiences by continuing to develop our technology infrastructure. The cost of developing our technology solutions is included in the overall cost structure of our services and is not separately funded by any individual advertisers or partners. In order to maintain a professional level of service and availability, we primarily rely upon third parties to provide hosting services, including hardware support and service, and network monitoring at various domestic and international locations. Our servers are configured for high availability and large volumes of call, mobile and Internet traffic and are located in leased third party facilities. Back-end databases make use of redundant servers and data storage arrays. We also have standby servers that provide for additional capacity as necessary. The facilities housing our servers provide redundant HVAC, power and internet connectivity. As revenue grows and the volume of transactions and call, mobile and internet traffic increases, we will need to expand our network infrastructure. Inefficiencies in our network infrastructure to scale and adapt to higher call, mobile and internet traffic volumes could materially and adversely affect our revenue and results of operations.

We continuously review ways to improve major aspects of our technology support and maintenance, including improving, upgrading and implementing business continuity plans, data retention initiatives, and backup and recovery processes.

Competition

Our call driven offerings currently or potentially compete with a variety of companies in a highly competitive and fragmented industry. We compete with leading search engines such as Google and Microsoft, digital advertising networks, mobile ad networks and call analytics technology providers. We also face competition on the call supply side, where competing companies look to outbid, partner with or otherwise secure sources of call supply we utilize. Our Archeo Domains Marketplace competitors include Demand Media, Name Media and Oversee.net. Many of our potential competitors, as well as potential entrants into our target markets, have longer operating histories, larger customer or user bases, greater brand recognition and greater financial, marketing and other resources than we have. Many current and potential competitors can devote substantially greater resources than we can to marketing, web site and systems development. In addition, as the use of the mobile, Internet, and other online services increases, there will likely be larger, more well-established and well-financed entities that acquire companies relevant to our business strategy; and invest in or form joint ventures in categories or countries relevant to our business strategy; all of which could adversely impact our business. Any of these trends could increase competition, reduce the demand for any of our services and could have a material adverse effect on our business, operating results and financial condition.

We believe our strategy allows us to work with most, if not all, of the relevant companies in our industry, even those companies that may be perceived as our competitors. To some extent, we may compete with our business partners, as we do with all other types of advertising sales companies and agencies. We may also compete with traditional offline media such as television, radio and print and direct marketing companies, for a share of advertisers’ total advertising budgets. Although our strategy enables us to work with most, if not all, of our competitors, there are no guarantees that all companies will view us as a potential partner.

We provide our services to and also may compete with: (1) mobile and online advertisers; (2) partners who provide a distribution network for mobile, online, and offline advertising; and (3) other intermediaries who may

Table of Contents

provide purchasing and/or sales opportunities, including advertising agencies, and other search engine marketing companies. Many of the companies that could fall into these categories are also our partners, including Google, Yahoo!, Citysearch, Microsoft and YP. We depend on maintaining and continually expanding our network of partners and advertisers to generate mobile and online transactions.

The mobile and online advertising and marketing services industry is highly competitive. In addition, we believe today’s typical Internet and mobile advertiser is becoming more sophisticated in utilizing the different forms of Internet and mobile advertising, purchasing Internet and mobile advertising in a cost-effective manner, and measuring return on investment. The competition for this pool of advertising dollars has also put downward pressure on price points and mobile and online advertisers have demanded more effective means of reaching customers. We believe these factors have contributed to the growth in performance-based advertising relative to certain other forms of online advertising and marketing, and as a result this sector has attracted many competitors.

Due to the long-term growth trends in mobile and online advertising, these competitors, real and potential, range in size and focus. Our competitors may include such diverse participants as small referral companies, established advertising agencies, inventory resellers, search engines, and destination web sites. We are also affected by the competition among destination web sites that reach users or customers of search services. While thousands of smaller outlets are available to customers, several large media and search engine companies, such as Google, Yahoo!, Microsoft and IAC, dominate online user traffic. The online search industry continues to experience consolidation of major web sites and search engines, which has the effect of increasing the negotiating power of these parties in relation to smaller providers. The major destination web sites and distribution providers may have leverage to demand more favorable contract terms, such as pricing, renewal and termination provisions.

There are additional competitive factors relating to attracting and retaining users, including the quality and relevance of our search results, and the usefulness, accessibility, integration and personalization of the mobile and online services that we offer as well as the overall user experience on our web sites. The other features that we offer, which we believe attract advertisers are reach, effectiveness and creativity of marketing services, and tools and information to help track performance.

Finally, we operate in the relatively nascent market of call-based advertising. The adoption of these call-based products could take longer than we expect and could become more competitive as the category becomes more developed and visible.

Seasonality

We believe we will experience seasonality. Our quarterly results have fluctuated in the past and may fluctuate in the future due to seasonal fluctuations in levels of mobile and Internet usage and seasonal purchasing cycles of many advertisers. Our experience has shown that during the spring and summer months, mobile and Internet usage is lower than during other times of the year and during the latter part of the fourth quarter of the calendar year we generally experience lower call volume and reduced demand for calls. The extent to which usage and call volume may decrease during these off-peak periods is difficult to predict. Prolonged or severe decreases in usage and call volume during these periods may adversely affect our growth rate and results. Additionally, the current business environment has generally resulted in advertisers and reseller partners reducing advertising and marketing services budgets or changing such budgets throughout the year, which we expect will impact our quarterly results of operations in addition to the typical seasonality seen in our industry. Our quarterly results will also be impacted by the timing of domain name sales which were recognized as revenue starting in September 2013 with the launch of our Domains Marketplace.

Intellectual Property and Proprietary Rights

We seek to protect our intellectual property through existing laws and regulations and by contractual restrictions. We rely upon trademark, patent and copyright law, trade secret protection and confidentiality or license agreements with our employees, customers, partners and others to help us protect our intellectual property.

Our technologies involve a combination of proprietary rights, owned and developed by us, commercially available software and hardware elements that are licensed or purchased by us from various providers, including Cisco, Dell, Oracle, Intel, Microsoft, IBM and Veritas, and public domain software, such as Apache, Linux, MySQL, IBM Java and Tomcat. We continue to develop additional technologies to update, supplement and replace existing components of the platform. We intend to protect our proprietary rights through patent and additional intellectual property laws.

Our policy is to apply for patents or for other appropriate intellectual property protection when we develop valuable new or improved technology. We currently own the following pending patent applications and issued patents:

10

Table of Contents

The status of any patent involves complex legal and factual questions. The scope of allowable claims is often uncertain. As a result, we cannot be sure that: (1) any patent application filed by us will result in a patent being issued; (2) that any patents issued in the future will afford adequate protection against competitors with similar technology; and (3) that the patents issued to us, if any, will not be infringed upon or designed around by others. Furthermore, the performance-based mobile and search advertising industry has been the subject of numerous patents and patent applications, which in turn has resulted in litigation. The mobile advertising industry is also witnessing a significant number of patent related lawsuits. The outcome of this ongoing litigation or any future claims in this sector may adversely affect our business or financial prospects.

We have registered trademarks in the United States for Adhere by Marchex, DPG, Form to Phone, Local Is The New Black, Marchex, Marchex and Design, Marchex Adhere, Marchex Adhere Logo, Marchex Voice Services, Openlist, JingleConnect and Jingle Networks. We also own pending U.S. trademark applications for Archeo, CALL DNA, A Logo, ARCHEO and Design, CALL GENOME, SEARCH GENOME and CLEAN CALL. In addition, we have trademark registrations for Marchex in the following jurisdictions: Australia, Benelux, Brazil, Canada, China, the European Union, Hong Kong, India, Japan, Republic of Korea, Russian Federation and Taiwan.

We do not know whether we will be able to successfully defend our proprietary rights since the validity, enforceability and scope of protection of proprietary rights in Internet-related industries are uncertain and still evolving.

Regulation

The manner in which existing laws and regulations should be applied to the Internet and call-based advertising services in general, and how they relate to our businesses in particular, is unclear. A host of federal and state laws covering user privacy, defamation, pricing, advertising, taxation, gambling, sweepstakes, promotions, financial market regulation, quality of products and services, computer trespass, telemarketing, spyware, adware, child protection and intellectual property ownership and infringement are potentially applicable to our business practices and the content offered by our mobile and online distribution partners.

In addition, our business is impacted by laws in a constant state of flux, and new legislation is introduced on a regular basis. Any such new legislation could expose us to substantial liability, including significant expenses

11

Table of Contents

necessary to comply with such laws and regulations. Courts may apply each of these laws in unintended and unexpected ways. As a company that provides services over the Internet as well as call recording and call tracking services, we may be subject to an action brought under any of these or future laws.

A number of federal and state laws that could have an impact on our business practices and compliance costs have already been adopted:

12

Table of Contents

In addition, there are a large number of federal and state legislative proposals related to our business. It is not possible to predict whether, or when, such legislation might be adopted, and certain proposals, if adopted, could result in a decrease in user registrations and revenue.

We comply with existing law and intend to fully comply with all future laws and regulations that may govern our industry. We have dedicated internal resources and hired outside professionals who regularly establish, review and maintain policies and procedures to reduce the risk of noncompliance. Nevertheless, these

laws may impose significant additional costs on our business or subject us to additional liability, if we failed to fully comply, even if such failure was unintentional.

The regulation of Internet domains in the United States and in foreign countries is subject to change. ICANN and other regulatory bodies could establish additional requirements for previously owned Internet domains or modify the requirements for Internet domains. Furthermore, ICANN has and will likely continue to make changes to the scope of domain products available to the marketplace that could have an impact on the competition for premium domain sales.

Compliance with complex foreign and U.S. laws and regulations that apply to our international operations increases our cost of doing business in international jurisdictions and could interfere with our ability to offer our products and services to one or more countries or expose us or our employees to fines and penalties. Our continued international expansion also subjects us to increased foreign currency exchange rate risks and will require additional management attention and resources. We cannot assure you that we will be successful in our international expansion.

We post a privacy policy which describes our practices concerning the use and disclosure of any user data collected or submitted via our web sites. Any failure by us to comply with our posted privacy policies, Federal Trade Commission requirements or other federal, state or international privacy or direct marketing laws and regulations could result in governmental or regulatory investigations that could potentially harm our businesses, operational results and overall financial condition.

Employees

As of December 31, 2013, we employed a total of 405 full-time employees. We have never had a work stoppage, and none of our employees are represented by a labor union. We consider our employee relationships to be positive. If we were unable to retain our key employees or we were unable to maintain adequate staffing of qualified employees, particularly during peak sales seasons, our business would be adversely affected.

An investment in our Class B common stock involves various risks, including those mentioned below and those that are discussed from time to time in our other periodic filings with the SEC. Investors should carefully

Table of Contents

consider these risks, along with the other information contained in this report, before making an investment decision regarding our stock. There may be additional risks of which we are currently unaware, or which we currently consider immaterial. All of these risks could have a material adverse effect on our business, financial condition, results of operations, and the value of our stock.

Risks Relating to Our Company

We have largely incurred net losses since our inception, and we may incur net losses in the foreseeable future.

We had an accumulated deficit of $171.1 million as of December 31, 2013. Our net expenses may increase based on the initiatives we undertake which for instance, may include increasing our sales and marketing activities, hiring additional personnel, incurring additional costs as a result of being a public company, acquiring additional businesses and making additional equity grants to our employees.

We are dependent on certain distribution partners, for distribution of our services, and we derive a significant portion of our total revenue through these distribution partners. A loss of distribution partners or a decrease in revenue from certain distribution partners could adversely affect our business.

A relatively small number of distribution partners currently deliver a significant percentage of calls and traffic to our advertisers. Our largest distribution partner was paid less than 15% of total revenues for the year ended December 31, 2013. Our existing agreements with many of our other larger distribution partners permit either company to terminate without penalty on short notice and are primarily structured on a variable-payment basis, under which we make payments based on a specified percentage of revenue or based on the number of paid phone calls or click-throughs. We intend to continue devoting resources in support of our larger distribution partners, but there are no guarantees that these relationships will remain in place over the short-or long-term. In addition, we cannot be assured that any of these distribution partners will continue to generate current levels of revenue for us or that we will be able to maintain the applicable variable payment terms at their current levels. A loss of any of these distribution partners or a decrease in revenue due to lower calls and traffic or less favorable variable payment terms from any one of these distribution relationships could have a material adverse effect on our business, financial condition and results of operations.

Companies distributing advertising through mobile or online Internet have experienced, and will likely continue to experience, consolidation. This consolidation has reduced the number of partners that control the mobile and online advertising outlets with the most user calls and traffic. According to the comScore qSearch analysis of the U.S. search marketplace for December 2013, Yahoo! and Microsoft accounted for 11% and 18%, respectively, of the core search market in the United States and Google accounted for 67%. As a result, the larger distribution partners have greater control over determining the market terms of distribution, including placement of call and click-based advertisements and cost of placement. In addition, many participants in the performance-based advertising and search marketing industries control significant portions of mobile and online traffic that they deliver to advertisers. We do not believe, for example, that Yahoo! and Google are as reliant as we are on a third party distribution network to deliver their services. This gives these companies a significant advantage over us in delivering their services, and with a lesser degree of risk.

We rely on certain advertiser reseller partners and agencies, including YP, hibu, Inc., The Cobalt Group, Super Media, Inc., Yodle and Yellow Media, Inc. for the purchase of various advertising and marketing services, as well as to provide us with a large number of advertisers. A loss of certain advertiser reseller partners and agencies or a decrease in revenue from these reseller partners could adversely affect our business. Such advertisers are subject to varying terms and conditions which may result in claims or credit risks to us.

We benefit from the established relationships and national sales teams that certain of our reseller partners, who are leading reseller partners of advertisers and advertising agencies, have in place throughout the U.S. and

15

Table of Contents

international markets. These advertiser reseller partners and agencies refer or bring advertisers to us for the purchase of various advertising products and services. We derive a sizeable portion of our total revenue through these advertiser reseller partners and agencies. Additionally, these advertiser reseller partners and agencies may decide to operate the advertising services we perform internally with their own teams and technology. A loss of certain advertiser reseller partners and agencies or a decrease in revenue from these clients could adversely affect our business. Through our contract with Yellowpages.com LLC d/b/a AT&T Interactive which is a subsidiary of AT&T (collectively, “AT&T”), our arrangement with AT&T relates to a business unit that is included in YP Holdings, LLC (“YP”) that AT&T sold a majority stake in to a private equity third party in April 2012. YP is our largest reseller partner and was responsible for 25% of our total revenues for the year ended December 31, 2013 of which the majority is derived from our local leads platform. We cannot predict whether our business with YP in the future will continue at or near current levels and any decrease in such levels could have a material adverse impact on our business and results of operations.

These advertisers may in certain cases be subject to negotiated terms and conditions separate from those applied to online clients accepted and processed through our automated advertiser management platform. In some cases, the applicable contract terms may be the result of legacy or industry association documentation or simply customized advertising solutions for large reseller partners and agencies. In any case, as a consequence of such varying terms and conditions, we may be subject to claims or credit risks that we may otherwise mitigate more efficiently across our automated advertiser management platform.

These claims and risks may vary depending on the nature of the aggregated client base. Among other claims, we may be subject to disputes based on third party tracking information or analysis. We may also be subject to differing credit profiles and risks based on the agency relationship associated with these advertisers. For such advertisers, payment may be made on an invoice basis, unlike our retail platform which in many instances is paid in advance of the service. In some limited circumstances we may also have accepted individual advertiser payment liability in place of liability of the advertising agency or media advisor.

We received approximately 53% and 61% of our revenue from our five largest customers for the year ended December 31, 2012 and 2013, respectively, and the loss of one or more of these customers could adversely impact our results of operations and financial condition.

Our five largest customers accounted for approximately 53% and 61% of our total revenues for the years ended December 31, 2012 and 2013, respectively. YP, ADT, and Allstate are our largest customers and were responsible for 25%, 13% and 12% of our total revenues for the year ended December 31, 2013, respectively, and 41%, 14% and 13% of accounts receivable at December 31, 2013, respectively. Most of these customers are not subject to long term contracts with us and are generally able to reduce advertising spending at any time and for any reason. A significant reduction in advertising spending by our largest customers, or the loss of one or more of these customers, if not replaced by new customers or an increase in business from existing customers, would adversely affect revenues. This could have a material adverse effect on our results of operations and financial condition.

Our large customers have substantial negotiating leverage, which may require that we agree to terms and conditions that may have an adverse effect on our business.

Our large customers have substantial purchasing power and leverage in negotiating contractual arrangements with us. These customers may seek for us to develop additional features, may require penalties for failure to deliver such features, may seek discounted product or service pricing and may seek more favorable contractual terms. As we sell more products and services to this class of customer, we may be required to agree to such terms and conditions. Such large customers also have substantial leverage in negotiating resolution of any disagreements or disputes that may arise. Any of the foregoing factors could result in a material adverse effect on our business, financial condition and results of operations.

If some of our customers experience financial distress or suffer disruptions in their business, their weakened financial position could negatively affect our own financial position and results.

We have a diverse customer base and, at any given time, one or more customers may experience financial distress, file for bankruptcy protection, go out of business, or suffer disruptions in their business. If a customer with whom we do a substantial amount of business experiences financial difficulty or suffers disruptions in their business, it could delay or jeopardize the collection of accounts receivable, result in significant reductions in services provided by us and may have a material adverse effect on our results of operations and liquidity.

We may incur liabilities for the activities of our advertisers, reseller partners, distribution partners and other users of our services, which could adversely affect our business.

Many of our advertisement generation and distribution processes are automated. In some cases, advertisers or reseller partners use our online tools and account management systems to create and submit advertiser listings and in other cases we create and submit advertising listings on behalf of our advertisers or reseller partners. These advertiser listings are submitted in a bulk data feed or through the distribution partners’ user interface. Although we monitor our distribution partners on an ongoing basis primarily for traffic quality, these partners control the distribution of the advertiser listings provided in the data feed or user interface submissions.

We have a large number of distribution partners who display our advertiser listings on their networks. Our advertiser listings are delivered to our distribution partners in an automated fashion through an XML data feed or data dump or through the distribution partners’ user interface. Our distribution partners are contractually required to use the listings created by our advertiser customers in accordance with applicable laws and regulations and in conformity with the publication restrictions in our agreements, which are intended to promote the quality and validity of the traffic provided to our advertisers. Nonetheless, we do not operationally control or manage these distribution partners and any breach of these agreements on the part of any distribution partner or its affiliates could result in liability for our business. These agreements include indemnification obligations on the part of our distribution partners, but there is no guarantee that we would be able to collect against offending distribution partners or their affiliates in the event of a claim under these indemnification provisions. Alternatively, we may incur substantial costs as part of our indemnification obligations to distribution partners for liability they may incur as a result of displaying content we have provided them.

We do not conduct a manual editorial review of a substantial number of the advertiser listings directly submitted by advertisers or reseller partners online, nor do we manually review the display of the vast majority of the advertiser listings by our distribution partners submitted to us by XML data feeds or data dumps or the distribution partners’ user interface. Likewise, in cases where we provide editorial or value-added services for our large reseller partners or agencies, such as ad creation and optimization for local advertisers or landing pages and micro-sites for pay-for-call customers, we rely on the content and information provided to us by these agents on behalf of their individual advertisers. We do not investigate the individual business activities of these advertisers other than the information provided to us or in some cases review of advertiser web sites. We may not successfully avoid liability for unlawful activities carried out by our advertisers or reseller partners and other users of our services or unpermitted uses of our advertiser listings by distribution partners and their affiliates.

Our potential liability for unlawful activities of our advertisers and other users of our services or unpermitted uses of our advertiser listings and advertising services and platform by distribution partners and reseller partners and agencies could require us to implement measures to reduce our exposure to such liability, which may require us, among other things, to spend substantial resources, to discontinue certain service offerings or to terminate certain distribution partner relationships. For example, as a result of the actions of advertisers in our network, we may be subject to private or governmental actions relating to a wide variety of issues, such as privacy, gambling, promotions, and intellectual property ownership and infringement. Under agreements with certain of our larger distribution partners, we may be required to indemnify these distribution partners against liabilities or losses resulting from the content of our advertiser listings, or resulting from third party intellectual property infringement claims. Although our advertisers agree to indemnify us with respect to claims arising from

17

Table of Contents

these listings, we may not be able to recover all or any of the liabilities or losses incurred by us as a result of the activities of our advertisers.

Our insurance policies may not provide coverage for liability arising out of activities of users of our services. In addition, our reliance on some content and information provided to us by our large advertiser reseller partners and agencies may expose us to liability not covered by our insurance policies. Furthermore, we may not be able to obtain or maintain adequate insurance coverage to reduce or limit the liabilities associated with our businesses. Any costs incurred as a result of such liability or asserted liability could have a material adverse effect on our business, operating results and financial condition.

If we do not maintain and grow a critical mass of advertisers and distribution partners, the value of our services could be adversely affected.

Our success depends, in large part, on the maintenance and growth of a critical mass of advertisers and distribution partners and a continued interest in our pay-for-call, performance-based advertising, call analytics and search marketing services. Advertisers will generally seek the most competitive return on investment from advertising and marketing services. Distribution partners will also seek the most favorable payment terms available in the market. Advertisers and distribution partners may change providers or the volume of business with a provider, unless the product and terms are competitive. In this environment, we must compete to acquire and maintain our network of advertisers and distribution partners. If our business is unable to maintain and grow our base of advertisers, our current distribution partners may be discouraged from continuing to work with us, and this may create obstacles for us to enter into agreements with new distribution partners. Our business also in part depends on certain of our large reseller partners and agencies to grow their base of advertisers as these advertisers become increasingly important to our business and our ability to attract additional distribution partners and opportunities. Similarly, if our distribution network does not grow and does not continue to improve over time, current and prospective advertisers and reseller partners and agencies may reduce or terminate this portion of their business with us. Any decline in the number of advertisers and distribution partners could adversely affect the value of our services.

The mobile advertising market may develop more slowly than expected, which could harm our business.

If the market for mobile marketing and advertising develops more slowly than we expect, our business could suffer. Our future success is highly dependent on the commitment of advertisers and marketers to mobile communications as an advertising and marketing medium, the willingness of our potential advertisers to outsource their mobile advertising and marketing needs, and our ability to sell our mobile advertising services to reseller partners and agencies. The mobile advertising and marketing market is relatively new and rapidly evolving. Businesses, including current and potential advertisers, may find mobile advertising or marketing to be less effective than traditional advertising media or marketing methods or other technologies for promoting their products and services. As a result, the future demand and market acceptance for mobile marketing and advertising is uncertain. Many of our current or potential advertisers have little or no experience using mobile communications for advertising or marketing purposes and have allocated only a limited portion of their advertising or marketing budgets to mobile communications advertising or marketing, and there is no certainty that they will allocate more funds in the future, if any. Funds to these types of campaigns may fluctuate greatly as different agencies and advertisers test and refine their overall marketing strategies to include mobile advertising and analytics tools. The adoption rate and budget commitments may vary from period to period as agencies and advertisers determine the appropriate mix of media and lead sources in short term and longer term campaigns.

We are dependent upon the quality of mobile, online, offline and other traffic sources in our network to provide value to our advertisers and the advertisers of our reseller partners, and any failure in our quality control could have a material adverse effect on the value of our services to our advertisers and adversely affect our revenues.

We utilize certain monitoring processes with respect to the quality of the mobile, online, offline and other traffic sources that we deliver to our advertisers. Among the factors we seek to monitor are sources and causes of low quality phone calls such as unwanted telemarketer calls and clicks such as non-human processes, including robots, spiders or other software, the mechanical automation of clicking, and other types of invalid clicks, click fraud, or click spam, the purpose of which is something other than to view the underlying content. Additionally, we also seek to identify other indicators which may suggest that a user may not be targeted by or desirable to our advertisers. Even with such monitoring in place, there is a risk that a certain amount of low quality mobile, online, offline and other traffic or traffic that is deemed to be less valuable by our advertisers will be delivered to such advertisers, which may be detrimental to those relationships. We have regularly refunded fees that our advertisers had paid to us which were attributed to low quality mobile, online, offline and other traffic. If we are unable to stop or reduce low quality Internet traffic and low quality phone calls, these refunds may increase. Low quality mobile, online, offline and other traffic may further prevent us from growing our base of advertisers and cause us to lose relationships with existing advertisers, or become the target of litigation, both of which would adversely affect our revenues.

We depend on being able to secure enough phone numbers to support our advertisers and other users of our services and any obstacles that we face which prevent us from meeting this demand could adversely affect our business.

We utilize phone numbers as part of a number of information and analytic services to advertisers, such as our pay-for-call, call tracking and call analytics services. Our services that utilize phone numbers are designed to enable advertisers and other users of our services to utilize mobile, online and offline advertising and to help measure the effectiveness of mobile, online and offline advertising campaigns. We secure a majority of our phone numbers through telecommunication carriers that we have contracted with and a smaller number through the 800 Service Management System, and such telecommunication carriers provide the underlying telephone service. Our telecommunications carriers and telephone number acquisition process are subject to the rules and guidelines established by the Federal Communications Commission. Furthermore, to the extent we offer call recording and pay-for-call services, we may be directly subject to certain telecommunications-related regulations. The Federal Communications Commission and our telecommunication carriers may change the rules and guidelines for securing phone numbers or change the requirements for retaining the phone numbers we have already secured. As a result, we may not be able to secure or retain sufficient phone numbers needed for our services. We may also be limited in the number of available telecommunications carriers or vendors to provide such phone numbers to us in the event of any industry consolidations.

Our acquisition of certain automated voice and mobile advertising-based technologies is heavily reliant on vendors.

Certain voice and mobile advertising-based products that we acquired as part of our acquisition of Jingle are heavily reliant on vendors. The free directory product that we provide relies on technology provided by third party vendors that include voice recognition software and business, government and residence data listings. We cannot guarantee that the technology, data and services provided by our third party vendors will be of sufficient quality to meet the demands of our customers and partners. Further, we cannot guarantee that the technologies, data and services will be available to us in the future on acceptable terms, if at all. Any perception by our customers or partners that our voice and mobile advertising-based products are incomplete or not of sufficient quality could lead to a loss in confidence by our customers or partners, which in turn could lead to a decline in revenues. If we are unable to continue maintaining, advancing and improving our voice and mobile advertising-based products, our operating results may be adversely affected.

We may be subject to intellectual property claims, which could adversely affect our financial condition and ability to use certain critical technologies, divert our resources and management attention from our business operations and create uncertainty about ownership of technology essential to our business.

Our success depends, in part, on our ability to operate without infringing on the intellectual property rights of others. There can be no guarantee that any of our intellectual property will not be challenged by third parties. We may be subject to patent infringement claims or other intellectual property infringement claims, including claims of trademark infringement in connection with our acquisition of previously-owned Internet domain names and claims of copyright infringement with respect to certain of our proprietary web sites that would be costly to defend and could limit our ability to use certain critical technologies.

The expansion of our call advertising business increases the potential intellectual property infringement claims we may be subject to, particularly in light of the large number of patents which have been issued (or are pending) in the telecommunications field over the last several decades, both in the U.S. and internationally. Jingle, which we acquired in 2011, was subject to patent infringement claims which were unsuccessful at trial. We resolved this matter and obtained a license to the patents at issue.

We believe that a consolidation of patent portfolios by major technology companies and independent asset holding companies will increase the chances of aggressive assertions of patent and other intellectual property claims. Within the technology telecommunications and online sectors, among other related sectors, we have witnessed various claim holders and alleged rights holders pursue business strategies devoted to extracting settlements or license fees for a wide range of basic and commonly accepted methods and practices. We may be subject to those intellectual property claims in the ordinary course of our business. Also, our partners and customers may also find that they are subject to similar claims, in which case we may be included in any related process or dispute settlement.

Any patent or other intellectual property litigation could negatively impact our business by diverting resources and management attention from other aspects of the business and adding uncertainty as to the ownership of technology, services and property that we view as proprietary and essential to our business. In addition, a successful claim of patent infringement against us and our failure or inability to license the infringed or similar technology on reasonable terms, or at all, could prevent us from using critical technologies which could have a material adverse effect on our business.

We may need additional funding to meet our obligations and to pursue our business strategy. Additional funding may not be available to us and our financial condition could therefore be adversely affected.

We may require additional funding to meet our ongoing obligations and to pursue our business strategy, which may include the selective acquisition of businesses and technologies. In addition, we have incurred and we may incur certain obligations in the future. There can be no assurance that if we were to need additional funds to meet these obligations that additional financing arrangements would be available in amounts or on terms acceptable to us, if at all. Furthermore, if adequate additional funds are not available, we will be required to delay, reduce the scope of, or eliminate material parts of the implementation of our business strategy, including potential additional acquisitions or internally-developed businesses.

Our acquisitions could divert management’s attention, cause ownership dilution to our stockholders, cause our earnings to decrease and be difficult to integrate.

Our business strategy includes identifying, structuring, completing and integrating acquisitions. Acquisitions in the technology and Internet sectors involve a high degree of risk. We may also be unable to find a sufficient number of attractive opportunities to meet our objectives which include revenue growth, profitability and competitive market share. Our acquired companies may have histories of net losses and may expect net losses for the foreseeable future. Acquisitions are accompanied by a number of risks that could harm our business, operating results and financial condition:

20

Table of Contents

Consequently, we might not be successful in integrating any acquired businesses, products or technologies, and might not achieve anticipated revenue and cost benefits.

Our expanding international operations subject us to additional risks and uncertainties and we may not be successful with our strategy to continue to expand such operations.

One potential area of growth for us is in international markets. We have initiated operations, through our subsidiaries, in Ireland and the United Kingdom. Our international expansion and the integration of international operations present unique challenges and risks. Compliance with complex foreign and U.S. laws and regulations that apply to our international operations increases our cost of doing business in international jurisdictions and could interfere with our ability to offer our products and services to one or more countries or expose us or our employees to fines and penalties. Our continued international expansion also subjects us to increased foreign currency exchange rate risks and will require additional management attention and resources. We cannot assure you that we will be successful in our international expansion. There are risks inherent in conducting business in international markets, including the need to localize our products and services to foreign customers’ preferences and customs, difficulties in managing operations due to language barriers, distance, staffing and cultural differences, application of foreign laws and regulations to us, tariffs and other trade barriers, fluctuations in currency exchange rates, establishing management systems and infrastructures, reduced protection for intellectual property rights in some countries, changes in foreign political and economic conditions, and potentially adverse tax consequences. Our failure to address these risks adequately could materially and adversely affect our business, revenue, results of operations and financial condition.

The loss of our senior management, including our executive officer founders, could harm our current and future operations and prospects.

We are heavily dependent upon the continued services of Russell C. Horowitz, our chairman and chief executive officer, and the other members of our senior management team. Each member of our senior management team is an at-will employee and may voluntarily terminate his employment with us at any time with minimal notice. Following any termination of employment, each of these employees would only be subject to a twelve-month non-competition and non-solicitation obligation with respect to our customers and employees under our standard confidentiality agreement. Further, as of December 31, 2013, Russell C. Horowitz, Ethan A. Caldwell and Peter Christothoulou, our executive officer founders, together controlled 87% of the combined voting power of our outstanding capital stock. Their collective voting control is not tied to their continued employment with Marchex. The loss of the services of any member of our senior management, including our executive officer founders, for any reason, or any conflict among our executive officer founders, could harm our current and future operations and prospects.

We may have difficulty retaining current personnel as well as attracting and retaining additional qualified, experienced, highly skilled personnel, which could adversely affect the implementation of our business plan.

Our performance is largely dependent upon the talents and efforts of highly skilled individuals. In order to fully implement our business plan, we will need to retain our current qualified personnel, as well as attract and retain additional qualified personnel. Thus, our success will in significant part depend upon our retention of current personnel as well as the efforts of personnel not yet identified and upon our ability to attract and retain highly skilled managerial, engineering, sales and marketing personnel. We are also dependent on managerial and technical personnel to the extent they may have knowledge or information about our businesses and technical systems that may not be known by our other personnel. There can be no assurance that we will be able to attract and retain necessary personnel. The failure to hire and retain such personnel could adversely affect the implementation of our business plan.

If we are unable to obtain and maintain adequate insurance, our financial condition could be adversely affected in the event of uninsured or inadequately insured loss or damage. Our ability to effectively recruit and retain qualified officers and directors may also be adversely affected if we experience difficulty in maintaining adequate directors’ and officers’ liability insurance.

We may not be able to obtain and maintain insurance policies on terms affordable to us that would adequately insure our business and property against damage, loss or claims by third parties. To the extent our business or property suffers any damages, losses or claims by third parties that are not covered or adequately covered by insurance, our financial condition may be materially adversely affected.

We currently have directors’ and officers’ liability insurance. If we are unable to maintain sufficient insurance as a public company to cover liability claims made against our officers and directors, we may not be able to retain or recruit qualified officers and directors to manage our company, which could have a material adverse effect on our operations.

It may be difficult for us to retain or attract qualified officers and directors, which could adversely affect our business and our ability to maintain the listing of our Class B common stock on the NASDAQ Global Select Market.

We may be unable to attract and retain qualified officers, directors and members of board committees required to provide for our effective management as a result of changes in the rules and regulations which govern publicly-held companies, including, but not limited to, certifications from executive officers and requirements for financial experts on boards of directors. The perceived increased personal risk associated with these changes may deter qualified individuals from accepting these roles. Further, applicable rules and regulations of the Securities and Exchange Commission and the NASDAQ Stock Market heighten the requirements for board or committee membership, particularly with respect to an individual’s independence from the corporation and level of experience in finance and accounting matters. We may have difficulty attracting and retaining directors with the requisite qualifications. If we are unable to attract and retain qualified officers and directors, our business and our ability to maintain the listing of our shares of Class B common stock on the NASDAQ Global Select Market could be adversely affected.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud, which could harm our brand and operating results.

Effective internal controls are necessary for us to provide reliable and accurate financial reports and effectively prevent fraud. We have devoted significant resources and time to comply with the internal control over financial reporting requirements of the Sarbanes-Oxley Act of 2002. In addition, Section 404 under the Sarbanes-Oxley Act of 2002 requires that we assess and our auditors attest to the effectiveness of our controls

22

Table of Contents

over financial reporting. Our current and future compliance with the annual internal control report requirement will depend on the effectiveness of our financial reporting and data systems and controls across our operating subsidiaries. We expect these systems and controls to become increasingly complex to the extent that we integrate acquisitions and our business grows. To effectively manage this growth, we will need to continue to improve our operational, financial and management controls and our reporting systems and procedures. We cannot be certain that these measures will ensure that we design, implement and maintain adequate controls over our financial processes and reporting in the future. Any failure to implement required new or improved controls, or difficulties encountered in their implementation or operation, could harm our operating results or cause us to fail to meet our financial reporting obligations. Inadequate internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our stock and our access to capital.

Impairment of goodwill and other intangible assets would result in a decrease in earnings.

Current accounting rules require that goodwill and other intangible assets with indefinite useful lives be tested for impairment at least annually. These rules also require that intangible assets with definite useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Events and circumstances considered in determining whether the carrying value of amortizable intangible assets and goodwill may not be recoverable include, but are not limited to, significant changes in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, or a significant decline in our stock price and/or market capitalization for a sustained period of time. To the extent such evaluation indicates that the useful lives of intangible assets are different than originally estimated, the amortization period is reduced or extended and, accordingly, the quarterly amortization expense is increased or decreased. To the extent such evaluation indicates that the useful lives of intangible assets are different than originally estimated, the amortization period is reduced or extended and, accordingly, amortization expense is increased or decreased.

We recorded a substantial non-cash impairment charge for goodwill and intangible assets during the fourth quarter of 2008 as a result of the impact of the adverse economic environment including the deterioration in the equity and credit markets. During the fourth quarter of 2012, we recorded a non-cash impairment charge for goodwill of $15.8 million within the Archeo reporting unit as a result of lower projected revenue growth rates and profitability levels compared to historical results and other market-based factors. We may be required to record a future charge to earnings in our financial statements during the period in which any additional impairment of our goodwill or amortizable intangible assets is determined. Any impairment charges or changes to the estimated amortization periods could have a material adverse effect on our financial results.

We may be required to increase or decrease the valuation allowance against our deferred tax assets.

Factors in our ability to realize a tax benefit from our deferred tax assets include tax attributes and operating results of acquired businesses, the nature, extent and periods that temporary differences are expected to reverse and our expectations about future operating results. We regularly review our deferred tax assets to assess whether or not it is more likely than not that the deferred tax assets will be realized, and if necessary, increase or decrease the valuation allowance for portions of such assets to reduce the carrying value. At the end of the fourth quarter of 2012, we recognized a partial valuation allowance of $16.4 million on our federal deferred tax assets which reduced our net deferred assets to $28.5 million. At the end of the second quarter of 2013, our gross deferred tax assets increased by approximately $651,000 due primarily to the 2012 and 2013 research and development credit which was reinstated as part the 2012 American Taxpayer Relief Act signed into law in January 2013. This increase was offset by a corresponding increase in our valuation allowance. If we determine that our deferred tax assets will not result in a future tax benefit, an additional valuation allowance may be recorded with a corresponding charge to net income. Such charges may have a material adverse effect on our results of operations or financial condition. The likelihood of recording such a valuation allowance may be impacted by our acquisitions and increases during periods of economic downturn.

We may not be able to realize the intended and anticipated benefits from our acquisitions of Internet domain names in part due to our increasing business focus on call advertising products, which could affect the value of these acquisitions to our business and our ability to meet our financial obligations and targets.

We may not be able to realize the intended and anticipated benefits from our acquisitions of Internet domain names in part due to our increasing focus on call advertising products. These intended and anticipated benefits included increasing our cash flow from operations, broadening our distribution offerings and delivering services that strengthen our advertiser relationships. In addition, our ability to maintain and grow revenues will also depend on maintaining and growing the number of domain name sales and the average revenue per domain. If we are unable to attract prospective buyers to purchase domains and at the price we value the domains, our revenue and results of operations could be materially and adversely affected.

We do not control the means by which users access our web sites, and material changes to current navigation practices or technologies or marketing practices or significant increases in our marketing costs could result in a material adverse effect on our business.

The success of our proprietary web site traffic sources depends in large part upon consumer access to our web sites. Consumers access our web sites primarily through the following methods: directly accessing our web sites by typing descriptive keywords or keyword strings into the uniform resource locator (URL) address box of an Internet browser; accessing our web sites by clicking on bookmarked web sites; and accessing our web sites through search engines and directories.

Each of these methods requires the use of a third party product or service, such as an Internet browser or search engine application or directory. Internet browsers may provide alternatives to the URL address box to locate web sites, and search engines may from time to time change and establish rules regarding the indexing and optimization of web sites. We also market certain web sites through search engine applications. Historically, we have limited our search engine marketing to less than five leading search engines.

Product developments and market practices for these means of access to our web sites are not within our control. We may experience a decline in traffic to our web sites if third party browser technologies or search engine methodologies and rules are changed to our disadvantage. We have experienced abrupt search engine algorithm and policy changes in the past. We expect the search engine applications we utilize to market and drive users to our web sites to continue to periodically change their algorithms, policies and technologies. These changes may result in an interruption in user’s ability to access our web sites or impair our ability to maintain and grow the number of users who visit our web sites. We may also be forced to significantly increase marketing expenditures in the event that market prices for online advertising and paid-listings escalate. Any of these changes could have a material adverse effect on our business.

We may experience unforeseen liabilities in connection with our acquisitions of Internet domain names or arising out of third party domain names included in our distribution network, which could negatively impact our financial results.

Certain of our acquisitions involved the acquisition of a large number of previously-owned Internet domain names. Furthermore, we have separately acquired and may acquire in the future additional previously-owned Internet domain names. In some cases, these acquired names may have trademark significance that is not readily apparent to us or is not identified by us in the bulk purchasing process. As a result we may face demands by third party trademark owners asserting infringement or dilution of their rights and seeking transfer of acquired Internet domain names under the Uniform Domain Name Dispute Resolution Policy administered by ICANN or actions under the U.S. Anti-Cybersquatting Consumer Protection Act. Additionally, we display pay-for-call or pay-per-click listings on third party domain names and third party web sites that are part of our distribution network, which also could subject us to a wide variety of civil claims including intellectual property ownership and infringement.

24

Table of Contents

We intend to review each claim or demand which may arise from time to time on its merits on a case-by-case basis with the assistance of counsel and we intend to transfer any rights acquired by us to any party that has demonstrated a valid prior right or claim. We cannot, however, guarantee that we will be able to resolve these disputes without litigation. The potential violation of third party intellectual property rights and potential causes of action under consumer protection laws may subject us to unforeseen liabilities including injunctions and judgments for money damages.

With the recent suspension of our previously announced spin off transaction, we may continue to explore various strategic alternatives for our Archeo assets.

In November 2012, we announced our intention to pursue the spin-off of our Archeo assets and in September 2013 following a strategic review, we announced the suspension of the planned spin-off of the Archeo assets in its previously announced form. At such time we announced our intention to explore various strategic alternatives for the Archeo assets. Archeo continues to operate as an independent division of the Company. We cannot predict whether Archeo will continue as such within our organization or whether we will pursue another strategic alternative for the Archeo assets going forward. If we do pursue another strategic alternative for the Archeo assets, there can be no assurances such efforts will be successful.

Risks Relating to Our Business and Our Industry

If we are unable to compete in the highly competitive performance-based advertising and search marketing industries, we may experience reduced demand for our products and services.

We operate in a highly competitive and changing environment. We principally compete with other companies which offer services in the following areas:

25

Table of Contents

Although we currently pursue a strategy that allows us to potentially partner with all relevant companies in the industry, there are certain companies in the industry that may not wish to partner with us. Despite the fact that we currently work with several of our potential competitors, there are no guarantees that these companies will continue to work with us in the future.

We currently or potentially compete with a variety of companies, including Google, Millennial Media, Microsoft, Mongoose Metrics and Telemetrics. Our Archeo Domains Marketplace competitors include Demand Media, Name Media and Oversee.net. Many of these actual or perceived competitors also currently or may in the future have business relationships with us, particularly in distribution. However, such companies may terminate their relationships with us. Furthermore, our competitors may be able to secure agreements with us on more favorable terms, which could reduce the usage of our services, increase the amount payable to our distribution partners, reduce total revenue and thereby have a material adverse effect on our business, operating results and financial condition. We expect competition to intensify in the future because current and new competitors can enter our market with little difficulty. The barriers to entering our market are relatively low. In fact, many current Internet and media companies presently have the technical capabilities and advertiser bases to enter the search marketing services industry. Further, if the consolidation trend continues among the larger media and search engine companies with greater brand recognition, the share of the market remaining for smaller search marketing services providers could decrease, even though the number of smaller providers could continue to increase. These factors could adversely affect our competitive position.

Some of our competitors, as well as potential entrants into our market, may be better positioned to succeed in this market. They may have:

Currently, and in the future, as the use of the Internet and other mobile and online services increases, there will likely be larger, more well-established and well-financed entities that acquire companies and/or invest in or form joint ventures in categories or countries of interest to us, all of which could adversely impact our business. Any of these trends could increase competition and reduce the demand for any of our services.

We face competition from traditional media companies, and we may not be included in the advertising budgets of large advertisers, which could harm our operating results.

In addition to Internet companies, we face competition from companies that offer traditional media advertising opportunities. Most large advertisers have set advertising budgets, a very small portion of which is allocated to Internet advertising. We expect that large advertisers will continue to focus most of their advertising efforts on traditional media. If we fail to convince these companies to spend a portion of their advertising budgets with us, or if our existing advertisers reduce the amount they spend on our programs, our operating results would be harmed.

If we are not able to respond to the rapid technological change characteristic of our industry, our products and services may cease to be competitive.

The market for our products and services is characterized by rapid change in business models and technological infrastructure, and we will need to constantly adapt to changing markets and technologies to

26

Table of Contents

provide new and competitive products and services. If we are unable to ensure that our users, advertisers, reseller partners, and distribution partners have a high-quality experience with our products and services, then they may become dissatisfied and move to competitors’ products and services. Accordingly, our future success will depend, in part, upon our ability to develop and offer competitive products and services for both our target market and for applications in new markets. We may not, however, be able to successfully do so, and our competitors may develop innovations that render our products and services obsolete or uncompetitive.

Our technical systems are vulnerable to interruption and damage that may be costly and time-consuming to resolve and may harm our business and reputation.

A disaster could interrupt our services for an indeterminate length of time and severely damage our business, prospects, financial condition and results of operations. Our systems and operations are vulnerable to damage or interruption from:

We may not have developed or implemented adequate protections or safeguards to overcome any of these events. We also may not have anticipated or addressed many of the potential events that could threaten or undermine our technology network. Any of these occurrences could cause material interruptions or delays in our business, result in the loss of data or render us unable to provide services to our customers. In addition, if a person is able to circumvent our security measures, he or she could destroy or misappropriate valuable information, including sensitive customer information, or disrupt our operations. We have deployed firewall hardware intended to thwart hacker attacks. Although we maintain property insurance and business interruption insurance, our insurance may not be adequate to compensate us for all losses that may occur as a result of a catastrophic system failure or other loss, and our insurers may not be able or may decline to do so for a variety of reasons. If we fail to address these issues in a timely manner, we may lose the confidence of our advertisers, reseller partners, and distribution partners, our revenue may decline and our business could suffer. In addition, as we expand our service offerings and enter into new business areas, we may be required to significantly modify and expand our software and technology platform. If we fail to accomplish these tasks in a timely manner, our business and reputation will likely suffer. Furthermore, some of these events could disrupt the economy and/or our customers’ business activities and in turn materially affect our operating results.

27

Table of Contents

We rely on third party technology, platforms, carriers, communications providers, and server and hardware providers, and a failure of service by these providers could adversely affect our business and reputation.

We rely upon third party colocation providers to host our main servers. If these providers are unable to handle current or higher volumes of use, experience any interruption in operations or cease operations for any reason or if we are unable to agree on satisfactory terms for continued hosting relationships, we would be forced to enter into a relationship with other service providers or assume hosting responsibilities ourselves. If we are forced to switch hosting facilities, we may not be successful in finding an alternative service provider on acceptable terms or in hosting the computer servers ourselves. We may also be limited in our remedies against these providers in the event of a failure of service. In the past, we have experienced short-term outages in the service maintained by one of our colocation providers.

We also rely on a select group of third party providers for components of our technology platform and support for our advertising and call-based services, such as hardware and software providers, telecommunications carriers and Voice over Internet Protocol (VoIP) providers, credit card processors and domain name registrars. As a result, key operational resources of our business are concentrated with a limited number of third party providers. A failure or limitation of service or available capacity by any of these third party providers could adversely affect our business and reputation. Furthermore, if any of these significant providers are unable to provide the levels of service and dedicated resources over time that we required in our business, we may not be able to replace certain of these providers in a manner that is efficient, cost-effective or satisfactory to our customers, and as a result our business could be materially and adversely affected. Short term or repeat problems with any of these service providers could provide an interruption of service or service quality impairment to significant customers, which could also impact materially our revenue in any period due to credits or potential loss of significant customers.

If our security measures are breached or are perceived as not being secure, we may lose advertisers, reseller partners and distribution partners and we may incur significant legal and financial exposure.

We store and transmit data and information about our advertisers, reseller partners, distribution partners and their respective users. We deploy security measures to protect this data and information, as do third parties we utilize to assist in data and information storage. Our security measures and those of the third parties we partner with to assist in data and information storage may suffer breaches. Security breaches of our data storage systems or our third party colocation and technology providers we utilize to store data and information relating to our advertisers, reseller partners, distribution partners and their respective users could expose us to significant potential liability. In addition, security breaches, actual or perceived, could result in the loss of advertisers, reseller partners and distribution partners that could potentially have an adverse effect on our business.

We may not be able to protect our intellectual property rights, which could result in our competitors marketing competing products and services utilizing our intellectual property and could adversely affect our competitive position.

Our success and ability to compete effectively are substantially dependent upon our internally developed and acquired technology and data resources, which we protect through a combination of copyright, trade secret, and patent and trademark law. To date, we have had issued or have applications pending for the following patents:

28

Table of Contents

29

Table of Contents

In the future, additional patents may be filed with respect to internally developed or acquired technologies. Our industry is highly competitive and many individuals and companies have sought to patent processes in the industry. We may decide not to protect certain intellectual properties or business methods which may later turn out to be significant to us. In addition, the patent process takes several years and involves considerable expense. Further, patent applications and patent positions in our industry are highly uncertain and involve complex legal and factual questions due in part to the number of competing technologies. As a result, we may not be able to successfully prosecute these patents, in whole or in part, or any additional patent filings that we may make in the future. We also depend on our trademarks, trade names and domain names. We may not be able to adequately protect our technology and data resources. In addition, intellectual property laws vary from country to country, and it may be more difficult to protect our intellectual property in some foreign jurisdictions in which we may plan to enter. If we fail to obtain and maintain patent or other intellectual property protection for our technology, our competitors could market competing products and services utilizing our technology.

Despite our efforts to protect our proprietary rights, unauthorized parties domestically and internationally may attempt to copy or otherwise obtain and use our services, technology and other intellectual property. We cannot be certain that the steps we have taken will prevent any misappropriation or confusion among consumers and advertisers. If we are unable to protect our intellectual property rights from unauthorized use, our competitive position could be adversely affected.

We may be involved in lawsuits to protect or enforce our patents, which could be expensive and time consuming.

We may initiate patent litigation against third parties to protect or enforce our patent rights, and we may be sued by others seeking to invalidate our patents or prevent the issuance of future patents. We may also become subject to interference proceedings conducted in the patent and trademark offices of various countries to determine the priority of inventions. The defense and prosecution, if necessary, of intellectual property suits, interference proceedings and related legal and administrative proceedings is costly and may divert our technical and management personnel from their normal responsibilities. We may not prevail in any of these suits. An adverse determination of any litigation or defense proceedings could put our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not being issued. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments in the litigation. If securities analysts or investors perceive these results to be negative, it could have an adverse effect on the trading price of our Class B common stock.

Our quarterly results of operations might fluctuate due to seasonality, which could adversely affect our growth rate and in turn the market price of our securities.

Our quarterly results have fluctuated in the past and may fluctuate in the future due to seasonal fluctuations in the level of mobile and Internet usage and seasonal purchasing cycles of many advertisers. Our experience has

30

Table of Contents

shown that during the spring and summer months of the year, mobile and Internet usage is lower than during other times of the year and during the latter part of the fourth quarter of the calendar year we generally experience lower call volume and reduced demand for calls. The extent to which usage and call volume may decrease during these off-peak periods is difficult to predict. Prolonged or severe decreases in usage and call volume during these periods may adversely affect our growth rate and in turn the market price of our securities. Additionally, the current business environment has resulted in many advertisers and reseller partners reducing advertising and marketing services budgets or changing such budgets throughout the year, which may impact our quarterly results of operations in addition to typical seasonality seen in our industry. Our quarterly results will also be impacted by the timing of domain name sales which were recognized as revenue starting in September 2013 with the launch of our Domains Marketplace.

We are susceptible to general economic conditions, and a downturn in advertising and marketing spending by advertisers could adversely affect our operating results.

Our operating results will be subject to fluctuations based on general economic conditions, in particular those conditions that impact advertiser-consumer transactions. Deterioration in economic conditions could cause decreases in or delays in advertising spending and reduce and/or negatively impact our short term ability to grow our revenues. Further, any decreased collectability of accounts receivable or early termination of agreements due to deterioration in economic conditions could negatively impact our results of operations.

We depend on the growth of mobile technologies, the Internet and the Internet infrastructure for our future growth and any decrease in growth or anticipated growth in mobile and Internet usage could adversely affect our business prospects.

Our future revenue and profits, if any, depend upon the continued widespread use of mobile technologies and the Internet as an effective commercial and business medium. Factors which could reduce the widespread use of mobile technologies (including mobile devices, in particular) and the Internet include:

In particular, concerns over the security of online transactions and the privacy of users, including the risk of identity theft, may inhibit the growth of Internet usage, including commercial transactions. In order for the mobile and online commerce market to develop successfully, we and other market participants must be able to transmit confidential information, including credit card information, securely over public networks. Any decrease in anticipated mobile and Internet growth and usage could have a material adverse effect on our business prospects.

We are exposed to risks associated with credit card fraud and credit payment, and we may continue to suffer losses as a result of fraudulent data or payment failure by advertisers.

We have suffered losses and may continue to suffer losses as a result of payments made with fraudulent credit card data. Our failure to control fraudulent credit card transactions could reduce our net revenue and gross margin and negatively impact our standing with applicable credit card authorization agencies. In addition, under limited circumstances, we extend credit to advertisers who may default on their accounts payable to us or fraudulently “charge-back” amounts on their credit cards for services that have already been delivered by us.

Regulation of E-Commerce, Online Tracking, Online Data Collection, and Use of the Internet may adversely affect our business and operating results.

Mobile and online search, e-commerce and related businesses face uncertainty related to new or future government regulation at the federal, state, and international levels regarding e-commerce, online tracking, online data collection, and use of the Internet. Due to the rapid growth and widespread use of the Internet, state and federal legislatures (both domestically and abroad) have enacted and may continue to enact various laws and regulations relating to the Internet. Individual states may also enact consumer protection laws that are more restrictive than the ones that already exist.

Furthermore, the application of existing laws and regulations to companies that engage in e-commerce, or otherwise interact with the Internet remains somewhat unclear. For example, as a result of the actions of advertisers in our network, we may be subject to existing laws and regulations relating to a wide variety of issues such as consumer privacy, gambling, sweepstakes, advertising, promotions, defamation, pricing, taxation, financial market regulation, quality of products and services, computer trespass, spyware, adware, child protection and intellectual property ownership and infringement. In addition, it is not clear whether existing laws that require licenses or permits for certain of our advertisers’ lines of business apply to us, including those related to insurance and securities brokerage, law offices and pharmacies. Existing federal and state laws that may affect the growth and profitability of our business include, among others:

32

Table of Contents

Many Internet services are automated, and companies such as ours may be unknowing conduits for illegal or prohibited materials. It is possible that some courts may impose a strict liability standard or require such companies to monitor their customers’ conduct. Although we would not be responsible or involved in any way in such illegal conduct, it is possible that we would somehow be held responsible for the actions of our advertisers or distribution partners.

We may also be subject to costs and liabilities with respect to privacy issues. Several companies have incurred penalties for failing to abide by the representations made in their public-facing privacy policies. In addition, several states have passed laws that require businesses to implement and maintain reasonable security procedures and practices to protect sensitive personal information and to provide notice to consumers in the event of a security breach. Further, it is anticipated that additional federal and state privacy-related legislation will be enacted. Such legislation could negatively affect our business.

In addition, foreign governments may pass laws that could negatively impact our business and/or may prosecute us for violating existing laws. Such laws might include EU member country conforming legislation under applicable EU Privacy, eCommerce, Telecommunications and Data Protection Directives. Any costs incurred in addressing foreign laws could negatively affect the viability of our business. Our exposure to this risk will increase to the extent we expand our operations internationally.

Federal and state regulation of telecommunications may adversely affect our business and operating results.

Subsidiaries of the Company provide information and analytics services to certain advertisers and reseller partners that may include information services. In connection therewith, the Company, through its subsidiaries, obtains certain telecommunications products and services from carriers in order to deliver these packages of information and analytic services.

Telecommunications laws and regulations (and interpretations thereof) are evolving in response to rapid changes in the telecommunications industry. If our carrier partners were to be subject to any changes in applicable law or regulation (or interpretations thereof), or additional taxes or surcharges, then we in turn may be subject to increased costs for their products and services or receive products and services that may be of less value to our customers, which in turn could adversely affect our business and operating results. Furthermore, our call recording and pay-for-call services may directly subject us to certain telecommunications-related regulations. Finally, in the event that any federal or state regulators were to expand the scope of applicable laws and regulations or their application to include certain end users and information service providers, then our business and operating results could also be adversely affected. The following existing and possible future federal and state laws could impact the growth and profitability of our business:

33

Table of Contents

State and local governments may in the future be permitted to levy additional taxes on Internet access and electronic commerce transactions, which could result in a decrease in the level of usage of our services. In addition, we may be required to pay additional income, sales, or other taxes.

On November 19, 2004, the federal government passed legislation placing a ban on state and local governments’ imposition of new taxes on Internet access or electronic commerce transactions which expires in November 2014. The proposed Marketplace Fairness Act of 2013 if enacted into law would allow states to require online and other out of state merchants to collect and remit sales and use tax on products and services that they may sell. An increase in taxes may make electronic commerce transactions less attractive for advertisers and businesses, which could result in a decrease in the level of usage of our services. Additionally, from time to time, various state, federal and other jurisdictional tax authorities undertake reviews of the Company and the Company’s filings. In evaluating the exposure associated with various tax filing positions, the Company on occasion accrues charges for probable exposures. We cannot predict the outcome of any of these reviews.

Risks Relating to Ownership of our Common Stock

Our Class B common stock prices have been and are likely to continue to be highly volatile.

The trading prices of our Class B common stock have been and are likely to continue to be highly volatile and subject to wide fluctuations. Since our initial public offering, the closing sale price of our Class B common stock on the NASDAQ Global Select Market ranged from $3.00 to $26.14 per share through December 31, 2013. Our stock prices may fluctuate in response to a number of events and factors, which may be the result of our business strategy or events beyond our control, including:

In addition, the stock market in general, and the NASDAQ Global Select Market and the market for mobile and online commerce companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the listed companies. These broad

35

Table of Contents

market and industry factors may seriously harm the market price of our Class B common stock, regardless of our operating performance. In the past, following periods of volatility in the market, securities class action litigation has often been instituted against these companies.

Litigation against us, whether or not judgment is entered against us, could result in substantial costs and potentially economic loss, and a diversion of our management’s attention and resources, any of which could seriously harm our financial condition. Additionally, there can be no assurance that an active trading market of our Class B common stock will be sustained.

Our executive officer founders control the outcome of stockholder voting, and there may be an adverse effect on the price of our Class B common stock due to the disparate voting rights of our Class A common stock and our Class B common stock.

As of December 31, 2013, Russell C. Horowitz, Ethan A. Caldwell and Peter Christothoulou, our executive officer founders, beneficially owned 100% of the outstanding shares of our Class A common stock, which shares represented 86% of the combined voting power of all outstanding shares of our capital stock. These executive officer founders together control 87% of the combined voting power of all outstanding shares of our capital stock. The holders of our Class A common stock and Class B common stock have identical rights except that the holders of our Class B common stock are entitled to one vote per share, while holders of our Class A common stock are entitled to twenty-five votes per share on all matters to be voted on by stockholders. This concentration of control could be disadvantageous to our other stockholders with interests different from those of these executive officer founders. This difference in the voting rights of our Class A common stock and Class B common stock could adversely affect the price of our Class B common stock to the extent that investors or any potential future purchaser of our shares of Class B common stock give greater value to the superior voting rights of our Class A common stock. Further, as long as these executive officer founders have a controlling interest, they will continue to be able to elect all or a majority of our board of directors and generally be able to determine the outcome of all corporate actions requiring stockholder approval. As a result, these executive officer founders will be in a position to continue to control all fundamental matters affecting our company, including any merger involving, sale of substantially all of the assets of, or change in control of, our company. The ability of these executive officer founders to control our company may result in our Class B common stock trading at a price lower than the price at which such stock would trade if these executive officer founders did not have a controlling interest in us. This control may deter or prevent a third party from acquiring us which could adversely affect the market price of our Class B common stock.

Anti-takeover provisions may limit the ability of another party to acquire us, which could cause our stock price to decline.

Our certificate of incorporation, as amended, our by-laws and Delaware law contain provisions that could discourage, delay or prevent a third party from acquiring us, even if doing so may be beneficial to our stockholders. In addition, these provisions could limit the price investors would be willing to pay in the future for shares of our Class B common stock. The following are examples of such provisions in our certificate of incorporation, as amended, or our by-laws:

We are also subject to Section 203 of the Delaware General Corporation Law, which provides, subject to enumerated exceptions, that if a person acquires 15% or more of our voting stock, the person is an “interested

36

Table of Contents

stockholder” and may not engage in “business combinations” with us for a period of three years from the time the person acquired 15% or more of our voting stock. The application of Section 203 of the Delaware General Corporation Law could have the effect of delaying or preventing a change of control of our company.

We may not be able to continue to pay dividends on our common stock in the future which could impair the value of such stock.

Under Delaware law, dividends to stockholders may be made only from the surplus of a company, or, in certain situations, from the net profits for the current fiscal year or the fiscal year before which the dividend is declared. We have initiated and paid a quarterly dividend on our common stock since November 2006. We accelerated and paid all four of our 2013 quarterly cash dividends on December 31, 2012. In January 2014, our board of directors declared a quarterly dividend in the amount of $0.02 per share on our Class A and Class B common stock, which was paid on February 18, 2014 to the holders of record as of the close of business on February 7, 2014. There is no assurance that we will be able to pay dividends in the future. Our ability to pay dividends in the future will depend on our financial results, liquidity and financial condition.

We will have broad discretion over the use of the net proceeds from any offering and may not use them effectively.

Our management may have broad discretion to use the net proceeds of any offering for a variety of purposes, including, further development of our products and operations, working capital and general corporate purposes. We may spend or invest these proceeds in a way with which our stockholders disagree. Failure by our management to effectively use these funds could harm our business and financial condition. Until the net proceeds of any offering are used, they may be placed in investments that do not yield a favorable return to our investors, do not produce significant income or lose value.

None.

Our headquarters are located in Seattle, Washington and consist of approximately 61,000 square feet of leased office space expiring in March 2018. We also lease additional office space in Las Vegas, Nevada, and New York, New York with lease terms expiring between April 2014 and March 2018. Our information technology systems are hosted and maintained in third party facilities under collocation services agreements. See Item 1 of this Annual Report on Form 10-K under the caption “Information Technology and Systems.”

We believe that our existing facilities, together with additional space we believe we can lease at reasonable market rates, are adequate for our near term business needs.

We are not a party to any material legal proceedings. From time to time, however, we may be subject to legal proceedings and claims in the ordinary course of business, including claims of alleged infringement of intellectual property rights, and a variety of claims arising in connection with our services.

Not Applicable.

PART II

Market Information

Our Class B common stock has been traded on the NASDAQ Global Select Market under the symbol “MCHX” since March 31, 2004 when we completed our initial public offering at a price of $6.50 per share. Prior to that time, there was no public market for our Class B common stock. The following table sets forth, for the periods indicated, the high and low closing sales prices for Marchex’s Class B common stock as reported on the NASDAQ Global Select Market:

Holders

As of February 26, 2014, there were 38,670,309 shares of common stock outstanding that were held by 53 stockholders of record. Of these shares:

Dividends

In November 2006, we initiated a quarterly cash dividend at $0.02 per share of Class A common stock and Class B common stock. In August 2012, our board of directors approved an increase to the quarterly cash dividend to Class A and Class B common stockholder from $0.02 per share to $0.035 per share. In December 2012, our board of directors declared a quarterly dividend for the first, second, third and fourth quarters of 2013 totaling $0.14 per share on our Class A common stock and Class B common stock which was paid on December 31, 2012 to holders of record as of the close of business on December 18, 2012. The dividend paid totaled approximately $5.3 million. In January 2014, our board of directors declared a quarterly dividend in the amount of $0.02 per share on its Class A and Class B common stock, which was paid on February 18, 2014 to the holders of record as of the close of business on February 7, 2014. This quarterly dividend totaled approximately $771,000. Although we expect that the annual cash dividend, subject to capital availability, will be $0.08 per common share or approximately $3.1 million for the foreseeable future, there can be no assurance that we will continue to pay dividends at such a rate or at all.

Overview

Marchex is a mobile and call advertising technology company. We provide products and services for businesses of all sizes that depend on consumer calls to drive sales. Our technology platform delivers performance-based, pay-for-call advertising across numerous of mobile and online publishers to connect millions of high-intent consumers with businesses over the phone. Our call analytics technology facilitates call quality, analyzes calls in real time and measures the outcomes of calls to close the loop between digital marketing and offline transactions. We help large national brands and small-and medium-sized businesses (“SMBs”) facilitate efficient and cost-effective marketing campaigns to drive calls and customer leads to their business. We provide a performance-based pay-per-click advertising service that connects advertisers with consumers across our owned and operated web sites as well as third party web sites and we also sell domain names.

Our technology-based products and services enable our customers to connect with consumers across leading third-party mobile and online channels, as well as our proprietary network of locally-focused web sites. We have direct relationships with large national advertisers and advertising agencies which utilize our products and services to plan, execute and measure their call-focused advertising campaigns. We also provide private-label performance marketing solutions for SMBs through a network of large reseller partners, which include Yellow Pages publishers, media and telecommunications companies and vertical marketing service providers. We enable these partners to sell pay-for-call advertising, call-analytics, search engine marketing and other digital marketing services to their millions of small business customers. We execute these campaigns for them using our technology. Our primary products offerings are:

Table of Contents

In addition to our call-driven business, we operate the Archeo Domains Marketplace, which enables the buying, selling and development of premium domain names, and includes more than 200,000 of our owned and operated websites. Our portfolio of websites contains more than 75,000 U.S. ZIP code sites, including 90210.com and covering ZIP code areas nationwide. The Archeo domain marketplace also consists of other locally-focused sites such as Yellow.com, OpenList.com and geo-targeted sites. We monetize this portfolio via pay-per-click and banner advertising and also make these domains available for sale to third parties.

We generate two categories of revenue. Call-driven revenue consists of payments from advertisers for pay-for-call marketing services and for use of our Call Analytics technology. Call-driven revenue also consists of payments from our reseller partners for use of our technology platform and marketing services, which they offer to their small business customers, as well as payments from advertisers for cost-per-action services. Archeo revenue includes revenue generated from advertisements on our network of owned and operated websites and third-party distribution, as well as from the sale of domain names in our domain marketplace. During the years ended December 31, 2011, 2012 and 2013, call-driven revenue accounted for approximately 73%, 84%, and 89% of total revenues, respectively. We operate primarily in domestic markets. For detail on revenue by geographical area for the three most recent fiscal years, see Note 13. Segment Reporting and Geographic Information of the notes to our consolidated financial statements.

We were incorporated in Delaware on January 17, 2003. Acquisition initiatives have played an important part in our corporate history to date.

We currently have offices in Seattle, Washington; Las Vegas, Nevada; and New York, New York.

Acquisition

On April 7, 2011, we acquired 100% of the stock of Jingle Networks, Inc. (“Jingle”) a provider of mobile voice search performance advertising and technology solutions in North America for the following consideration:

Following the closing, we issued 462,247 shares of restricted stock at an aggregate value of approximately $3.3 million to employees of Jingle, subject to vesting for up to four years.

The fair value of the shares of Class B common stock issued as part of the consideration paid was valued at $7.6 million using the Company’s closing stock price of $7.46 per share at the acquisition date.

Proposed Separation Update

On November 1, 2012, we announced that our board of directors had authorized us to pursue the separation of our mobile advertising business focused on calls and Archeo, a domain and click-based advertising business. On September 19, 2013, we announced following a strategic review that it would no longer pursue the separation and that Archeo will continue to operate as a division. We will continue to evaluate various strategic alternatives for the Archeo assets.

Consolidated Statements of Operations

The assets, liabilities and operations of our acquisitions are included in our consolidated financial statements as of the date of the respective acquisitions.

All significant inter-company transactions and balances within Marchex have been eliminated in consolidation. Our purchase accounting resulted in all assets and liabilities from our acquisitions being recorded at their estimated fair values on the respective acquisition dates. All goodwill, intangible assets and liabilities resulting from the acquisitions have been recorded in our consolidated financial statements.

In the third quarter of 2013, we sold certain assets related to our pay-per-click contextual advertising services in which the operating results have been classified and presented as discontinued operations, net of tax (see Note 14. Discontinued Operations) as well as revised our segment reporting to reflect the change in segment performance measures for all periods presented (see Note 13. Segment Reporting and Geographic Information).

Presentation of Financial Reporting Periods

The comparative periods presented are for the years ended December 31, 2011, 2012 and 2013.

Revenue

We currently generate revenue through our call advertising services, pay-per-click advertising, local leads platform which include our call and click services, proprietary web site traffic and domain name sales through our Domains Marketplace.

Our primary sources of revenue are the performance-based advertising services, which include call advertising, pay-per-click services and cost-per-action services. These primary sources amounted to more than 77% of our revenues in all periods presented. Our secondary sources of revenue are our local leads platform which enables partner resellers to sell call advertising and/or search marketing products, campaign management services, and starting in September 2013, domain name sales through our Domains Marketplace. These secondary sources amounted to less than 23% of our revenues in all periods presented. We have no barter transactions.

On September 10, 2013, we launched our Domains Marketplace, which provides domain names available for sale and initiated plans to facilitate the active buying and transacting of domain names. Domain name sales occurring after this launch have been recognized as revenue in the consolidated financial statements. Historically, the sale of domain names were not a core operation and were peripheral to the generation of advertising revenue from domain names held for use, and as such, domain name sales were reported as gains on sales and disposals of intangible assets, net in the consolidated financial statements.

We recognize revenue upon the completion of our performance obligation, provided that: (1) evidence of an arrangement exists; (2) the arrangement fee is fixed and determinable; and (3) collection is reasonably assured.

45

Table of Contents

In certain cases, we record revenue based on available and reported preliminary information from third parties. Collection on the related receivables may vary from reported information based upon third party refinement of the estimated and reported amounts owing that occurs subsequent to period ends.

Performance-Based Advertising Services

In providing call advertising services and pay-per-click advertising, we generate revenue upon our delivery of qualified and reported phone calls or click-throughs to our advertisers or advertising service providers’ listings. These advertisers and advertising service providers pay us a designated transaction fee for each phone call or click-through, which occurs when a user makes a phone call or clicks on any of their advertisement listings after it has been placed by us or by our distribution partners. Each phone call or click-through on an advertisement listing represents a completed transaction. The advertisement listings are displayed within our distribution network, which includes mobile and online search engines and applications, directories, destination sites, shopping engines, third party Internet domains or web sites, our portfolio of owned web sites, other targeted Web-based content and offline sources. We also generate revenue from cost-per-action services, which occurs when a user makes a phone call from our advertiser’s listing or is redirected from one of our web sites or a third party web site in our distribution network to an advertiser web site and completes the specified action.

We generate revenue from reseller partners and publishers utilizing our local leads platform to sell call advertising or, search marketing and other lead generation products. We are paid account fees and also agency fees for our products in the form of a percentage of the cost of every call or click delivered to advertisers. The reseller partners or publishers engage the advertisers and are the primary obligor, and we, in certain instances, are only financially liable to the publishers in our capacity as a collection agency for the amount collected from the advertisers. We recognize revenue for these fees under the net revenue recognition method. In limited arrangements resellers pay us a fee for fulfilling an advertiser’s campaign in our distribution network and we act as the primary obligor. We recognize revenue for these fees under the gross revenue recognition method.

In providing pay-per-click contextual targeting services, advertisers purchase keywords or keyword strings, based on an amount they choose for a targeted placement on vertically-focused web sites or specific pages of a web site that are specific to their products or services and their marketing objectives. The contextual results distributed by our services are prioritized for users by the amount the advertiser is willing to pay each time a user clicks on the merchant’s advertisement and the relevance of the merchant’s advertisement, which is dictated by historical click-through rates. Advertisers pay us when a click-through occurs on their advertisement. In July 2013, we sold certain assets related to our pay-per-click contextual advertising services. The results of operations of these certain pay-per-click assets have been presented in the consolidated financial statements as discontinued operations. See Note 14. Discontinued Operations for further discussion.

Search Marketing Services and Domains Name Sales

Advertisers pay us additional fees for services such as campaign management. Advertisers generally pay us on a click-through basis, although in certain cases we receive a fixed fee for delivery of these services. In some cases we also deliver banner campaigns for select advertisers. We may also charge initial set-up, account, service or inclusion fees as part of our services.

Banner advertising revenue may be based on a fixed fee per click and is generated and recognized on click-through activity. In other cases, banner payment terms are volume-based with revenue generated and recognized when impressions are delivered.

Non-refundable account set-up fees are paid by advertisers and are recognized ratably over the longer of the term of the contract or the average expected advertiser relationship period, which generally ranges from twelve months to more than two years. Other account and service fees are recognized in the month or period the account fee or services relate to.

We generate revenue from domain name sales through our Domains Marketplace. Our Domains Marketplace was launched in September 2013 and provides domain names available for sale and initiated plans to facilitate the buying and transacting of domain names. Domain name sales occurring after the launch date are recognized as revenue.

Industry and Market Factors

We enter into agreements with various mobile, online and offline distribution partners to provide distribution for pay-for-call and pay-per-click advertisement listings which contain call tracking numbers and/or URL strings of our advertisers. We generally pay distribution partners based on a percentage of revenue or a fixed amount for each phone call or per click-through on these listings. The level of phone calls and click-throughs contributed by our distribution partners has varied, and we expect it will continue to vary, from quarter to quarter and year to year, sometimes significantly. If we do not add new distribution partners, renew our current distribution partner agreements, replace traffic lost from terminated distribution agreements with other sources or if our distribution partners’ search businesses do not grow or are adversely affected, our revenue and results of operations may be materially and adversely affected. Our ability to grow will be impacted by our ability to increase our distribution, which impacts the number of mobile and Internet users who have access to our advertisers’ listings and the rate at which our advertisers are able to convert calls and clicks from these mobile and Internet users into completed transactions, such as a purchase or sign up. Our ability to grow also depends on our ability to continue to increase the number of advertisers who use our services and the amount these advertisers spend on our services.

We anticipate that these variables will fluctuate in the future, affecting our ability to grow and our financial results. In particular, it is difficult to project the number of phone calls or click-throughs which will be delivered to our advertisers and how much advertisers will spend with us, and it is even more difficult to anticipate the average revenue per phone call or click-through. It is also difficult to anticipate the impact of worldwide economic conditions on advertising budgets.

In addition, we believe we will experience seasonality. Our quarterly results have fluctuated in the past and may fluctuate in the future due to seasonal fluctuations in levels of mobile and Internet usage and seasonal purchasing cycles of many advertisers. Our experience has shown that during the spring and summer months, mobile and Internet usage is lower than during other times of the year and during the latter part of the fourth quarter of the calendar year we generally experience lower call volume and reduced demand for calls. The extent to which usage and call volume may decrease during these off-peak periods is difficult to predict. Prolonged or severe decreases in usage and call volume during these periods may adversely affect our growth rate and results. Additionally, the current business environment has generally resulted in advertisers and reseller partners reducing advertising and marketing services budgets or changing such budgets throughout the year, which we expect will impact our quarterly results of operations in addition to the typical seasonality seen in our industry. Our quarterly results will also be impacted by the timing of domain name sales which were recognized as revenue starting in September 2013 with the launch of our Domains Marketplace.

Service Costs

Our service costs represent the cost of providing our performance-based advertising services and our search marketing services. The service costs that we have incurred in the periods presented primarily include:

Table of Contents

User Acquisition Costs

For the periods presented the largest component of our service costs consist of user acquisition costs that relate primarily to payments made to distribution partners for access to their mobile, online, offline, or other user traffic. We enter into agreements of varying durations with distribution partners that integrate our services into their web sites and indexes. The primary economic structure of the distribution partner agreements is a variable payment based on a specified percentage of revenue. These variable payments are often subject to minimum payment amounts per phone call or click-through. Other payment structures that to a lesser degree exist include:

We expense user acquisition costs based on whether the agreement provides for fixed or variable payments. Agreements with fixed payments with minimum guaranteed amounts of usage are expensed as the greater of the pro-rata amount over the term of arrangement or the actual usage delivered to date based on the contractual revenue share. Agreements with variable payments based on a percentage of revenue, number of paid phone calls, click-throughs or other metrics are expensed as incurred based on the volume of the underlying activity or revenue multiplied by the agreed-upon price or rate.

Sales and Marketing

Sales and marketing expenses consist primarily of:

Product Development

Product development costs consist primarily of expenses incurred in the research and development, creation and enhancement of our web sites and services.

48

Table of Contents

Our research and development expenses include:

For the periods presented, substantially all of our product development expenses are research and development.

Product development costs are expensed as incurred or capitalized into property and equipment in accordance with FASB ASC 350. This statement requires that costs incurred in the preliminary project and post-implementation stages of an internal use software project be expensed as incurred and that certain costs incurred in the application development stage of a project be capitalized.

General and Administrative

General and administrative expenses consist primarily of:

Stock-Based Compensation

We measure stock-based compensation cost at the grant date based on the fair value of the award and recognize it as expense, net of estimated forfeitures, over the vesting or service period, as applicable, of the stock award using the straight-line method. Stock-based compensation expense has been included in the same lines as compensation paid to the same employees in the consolidated statement of operations.

Amortization of Intangibles from Acquisitions

Amortization of intangible assets excluding goodwill relates to intangible assets identified in connection with our acquisitions.

The intangible assets have been identified as:

These assets are amortized over useful lives ranging from 12 to 84 months.

Provision for Income Taxes

We utilize the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax law is recognized in results of operations in the period that includes the enactment date.

Each reporting period we must assess the likelihood that our deferred tax assets will be recovered from existing deferred tax liabilities or future taxable income, and to the extent that realization is not more likely than not, a valuation allowance must be established. The establishment of a valuation allowance and increases to such an allowance may result in either an increase to income tax expense or reduction of income tax benefit in the statement of operations. Although realization is not assured, we believe it is more likely than not, based on operating performance, existing deferred tax liabilities, projections of future taxable income and tax planning strategies, that our net deferred tax assets, excluding certain state and foreign NOL carryforwards, will be realized. In determining that it was more likely than not that we would realize the deferred tax assets, factors considered included: historical taxable income, historical trends related to advertiser usage rates, projected revenues and expenses, macroeconomic conditions and issues facing our industry, existing contracts, our ability to project future results and any appreciation of our other assets.

As of December 31, 2013, we have net deferred tax assets of $26.2 million, relating to the impairment of goodwill, amortization of intangibles assets, certain other temporary differences, acquired federal and state net operating loss carryforwards, and research and development credits. At December 31, 2012 and 2013, we have recorded a valuation allowance of $21.6 million and $23.0 million, respectively, against our federal net deferred tax assets as we believe it is more likely than not that these benefits will not be realized. The change in the valuation allowance in 2013 was approximately $1.4 million due to an increase in our deferred tax assets primarily related to the 2012 and 2013 research and development credit and federal and state NOLs recorded during 2013.

Each reporting period we must assess the likelihood that our deferred tax assets will be recovered from existing deferred tax liabilities or future taxable income, and to the extent that realization is not more likely than not, a valuation allowance must be established. The establishment of a valuation allowance and increases to such an allowance may result in either an increase to income tax expense or reduction of income tax benefit in the statement of operations. Although realization is not assured, we believe it is more likely than not, based on operating performance, existing deferred tax liabilities, projections of future taxable income and tax planning strategies, that our net deferred tax assets, excluding certain state and foreign NOL carryforwards, will be realized. In determining that it was more likely than not that we would realize the deferred tax assets, factors considered included: historical taxable income, historical trends related to advertiser usage rates, projected revenues and expenses, macroeconomic conditions and issues facing our industry, existing contracts, our ability to project future results and any appreciation of our other assets.

The majority of our deferred tax assets are from goodwill and intangible assets recorded in connection with various acquisitions that are tax-deductible over 15 year periods. Based on projections of future taxable income and tax planning strategies, we expect to be able to recover these assets. The amount of the net deferred tax assets considered realizable, however, may be reduced in the near term if our projections of future taxable income are reduced or if we do not perform at the levels we are projecting. This may result in increases to the valuation allowance for deferred tax assets and may increase income tax expense of up to the entire net amount of deferred tax assets.

As of December 31, 2013, based upon both positive and negative evidence available, we have determined it is not more likely than not that certain deferred tax assets primarily relating to NOL carryforwards in certain

50

Table of Contents

state, city, and foreign jurisdictions will be realizable and accordingly, have recorded a 100% valuation allowance of $6.0 million against these deferred tax assets. We do not have a history of taxable income in the relevant jurisdictions and the state and foreign NOL carryforwards will more likely than not expire unutilized. Should we determine in the future that we will be able to realize these deferred tax assets, or not be able to realize all or part of our remaining net deferred tax assets recorded as of December 31, 2013, an adjustment to the net deferred tax assets would impact net income or stockholders’ equity in the period such determination was made.

As of December 31, 2012 and 2013, we had certain federal NOL carryforwards of $1.7 million which will begin to expire in 2019. The Tax Reform Act of 1986 limits the use of NOL and tax credit carryforwards in certain situations where changes occur in the stock ownership of a company. We believe that such a change has occurred, and that approximately $1.7 million of NOL carryforwards is limited such that substantially all of these federal NOL carryforwards will never be available. Accordingly, we have not recorded a deferred tax asset for these NOL’s.

In connection with the Jingle acquisition in 2011, we acquired federal NOL carryforwards. Where there is a “change in ownership” within the meaning of Section 382 of the Internal Revenue Code, the acquired federal net operating loss carryforwards are subject to an annual limitation. We believe that such an ownership change had occurred at Jingle, and that the utilization of the carryforwards is limited such that the majority of the NOL carryforwards will never be utilized. Accordingly, we have not recorded those amounts we believe it will not be able to utilize and has not included those NOL carryforwards in its deferred tax assets. We recorded NOL carryforwards that may be utilized of approximately $7.0 million in which $2.6 million was utilized in 2011.

From time to time, various state, federal, and other jurisdictional tax authorities undertake reviews of us and our filings. We believe any adjustments that may ultimately be required as a result of any of these reviews will not be material to the financial statements.

Comparison of the year ended December 31, 2012 (2012) to the year ended December 31, 2013 (2013) and comparison of the year ended December 31, 2011 (2011) to the year ended December 31, 2012 (2012).

Segments

We have organized our operations into two segments: (1) the Call-driven segment which is comprised of our performance-based advertising business focused on driving phone calls; and (2) the Archeo segment which is comprised of our click-based advertising and Internet domain name businesses. In the third quarter of 2013, we changed our segment reporting to reflect the reallocation of our general corporate overhead expenses to the Call-driven segment to reflect changes in how the CODM internally measures segment performance. The tables below reflect these reclassifications to conform to the current presentation.

Table of Contents

In July 2013, we sold certain assets related to Archeo’s pay per click advertising services. As a result, the operating results related to these certain pay per click assets are shown as discontinued operations, net of tax in the consolidated statements of operations for all periods presented and are excluded from segment reporting. See Note. 14 Discontinued Operations for further discussion.

Revenue.

The following table presents our revenues, by revenue source, for the periods presented:
