OVERVIEW

ValueClick, Inc. and its subsidiaries (collectively "ValueClick" or the "Company" or in the first person, "we", "us" and "our") is one of the world's largest and most comprehensive online marketing services companies. We sell targeted and measurable online advertising campaigns and programs for advertisers and advertising agency customers, generating qualified customer leads, online sales and increased brand recognition on their behalf with large numbers of online consumers.

Our customers are primarily direct marketers, brand advertisers and the advertising agencies that service these groups. The proposition we offer our customers includes: one of the industry's broadest online marketing services portfolios-including performance-based campaigns and programs where marketers only pay for advertising when it generates a customer lead or product sale; our ability to target campaigns to reach the online consumers our customers are most interested in; and the scale at which we can deliver results for online advertising campaigns. Additionally, our networks of online publishers provide advertisers with a cost-effective and complementary source of online consumers relative to online portals and other large website publishers. Through this approach we have become an industry leader in generating qualified customer leads and online sales for advertisers.

We generate the audiences for our advertisers' campaigns primarily through networks of third-party websites, other online publisher partners and search engines. We aggregate our publisher partners' online advertising inventory into networks, optimize these networks for specific marketing goals, and deliver the campaigns across the appropriate networks' advertising inventory. We are one of the industry's largest online network providers, with: industry expertise and proprietary technology platforms for online advertising inventory aggregation; campaign targeting and optimization, delivery, measurement, and reporting; and, payment settlement and delivery services.

Our publisher partners enjoy efficient and effective monetization of their online advertising inventory through representation by our direct sales teams in major U.S. and European media markets, participation in large-scale advertiser and advertising agency campaigns they may not have access to on their own, enhanced monetization through our proprietary campaign optimization and targeting technology, and settlement services to facilitate payments to publishers for the online inventory utilized by the advertisers. As we do not primarily own and operate websites that compete directly with our publisher partners for online consumers, we act as a trusted partner in helping online publishers monetize their online audience and advertising inventory.

We believe that the effectiveness of our online marketing services is dependent on the quality of our networks and our publisher partner relationships. As such, we have established stringent quality standards that include publisher rejection

from our networks due to inappropriate content, illegal activity and fraudulent clicking activity, among other criteria. We enforce these quality standards using a combination of manual and automated auditing processes that continually monitor and review both website content and adherence to advertiser campaign specifications.

We derive our revenue from four business segments. These business segments are presented on a worldwide basis and include Media, Affiliate Marketing, Comparison Shopping & Search, and Technology, which are described in more detail below.

MEDIA

ValueClick's Media segment provides a comprehensive suite of online marketing services and tailored programs that help marketers create and increase awareness for their products and brands, attract visitors and generate leads and sales through the Internet. We provide powerful offerings to advertiser and advertising agency customers in the following product categories: display advertising and lead generation marketing. Prior to October 2008, we also sold a limited number of consumer products directly to end-user customers through Company-owned e-commerce websites. We divested our interest in the e-commerce websites in October 2008 as further discussed in note 4 "Discontinued Operations" to our condensed consolidated financial statements contained in this quarterly report on form 10-Q. Our Media services are sold on a variety of pricing models, including cost-per-lead ("CPL"), cost-per-action ("CPA"), cost-per-thousand-impression ("CPM"), and cost-per-click ("CPC").

AFFILIATE MARKETING

Through the combination of: a large-scale pay-for-performance model built on our proprietary technology platforms; marketing expertise; and a large, quality advertising network, our Affiliate Marketing business enables advertisers to develop their own fully-commissioned online sales force comprised of third-party affiliate publishers. We believe we are the largest provider of affiliate marketing services. Our Affiliate Marketing segment services, including search engine marketing ("SEM"), are offered through our wholly-owned subsidiary Commission Junction.

Affiliate Marketing segment revenues are principally driven by variable compensation that is generally based on either a percentage of commissions paid to affiliates or on a percentage of transaction revenue generated from the programs managed with our Affiliate Marketing platforms. SEM revenues are driven primarily by a percentage of the revenue we generate for our advertiser customers.

COMPARISON SHOPPING & SEARCH

Our online Comparison Shopping services enable consumers to research and compare products from among thousands of online and/or offline merchants using our proprietary technologies. We gather product and merchant data and organize it into comprehensive catalogs on our destination websites, along with relevant consumer and professional reviews. Our services are free for consumers, and our customers primarily pay us on a CPC basis for traffic delivered to the customers' websites from listings on our websites.

Our Comparison Shopping & Search segment services are offered through our wholly-owned subsidiaries Pricerunner, Shopping.net and MeziMedia. Pricerunner operates comparison shopping destination websites in the United Kingdom, Sweden, Germany, France, Denmark, and Austria. Shopping.net operates in the United Kingdom. MeziMedia, acquired in July 2007, operates its comparison shopping destination websites primarily in the United States under the Smarter.com, Shopica.com and Couponmountain.com brand names.

In addition to our Pricerunner and MeziMedia comparison shopping destination websites, Search123, which operates in Europe, is ValueClick's self-service paid search offering that generates its traffic primarily through syndication relationships with other search engines, Web portals and content websites. Search syndication revenues are driven primarily on a CPC basis.

TECHNOLOGY

Our Technology segment provides advertisers, advertising agencies, website publishers, and other companies with the tools they need to effectively manage their online marketing programs. Our technology products and services are offered through our wholly-owned subsidiary Mediaplex, Inc., acquired in October 2001. Mediaplex Systems was also included in our Technology segment until its divestiture in October 2008 as further discussed in note 4 "Discontinued Operations" to our condensed consolidated financial statements contained in this quarterly report on form 10-Q. Mediaplex is an application services provider ("ASP") offering technology infrastructure tools and services that enable marketers to implement and manage their own online advertising programs across multiple channels including display, email, paid search, natural search, on-site, offline and affiliate. Our Mediaplex products are based on our proprietary MOJOŽ technology platform, which has the ability, among other attributes, to automatically configure advertisements in response to real-time information from an advertiser's

enterprise data system and to provide ongoing campaign optimization and analytics. Mediaplex's products are priced primarily on a CPM or email-delivered basis.

SEGMENT OPERATING RESULTS

The following table provides revenue, cost of revenue, gross profit, operating expenses, and income from operations information for each of our four business segments. Segment income from operations, as shown below, is the performance measure used by management to assess segment performance and excludes the effects of: stock-based compensation, amortization of intangible assets and corporate expenses. Corporate expenses consist of those costs not directly attributable to a business segment, and include: salaries and benefits for our executive, finance, legal, corporate governance, human resources, and facilities organizations; fees for professional service providers including audit, legal, tax, and Sarbanes-Oxley compliance; insurance; and, other corporate expenses. A reconciliation of segment income from operations to consolidated income from operations and a reconciliation of segment revenue to consolidated revenue are also provided in the following table.

RESULTS OF OPERATIONS-THREE-MONTH PERIOD ENDED MARCH 31, 2009 COMPARED TO
MARCH 31, 2008

Revenue. Consolidated revenue for the three-month period ended March 31, 2009 was $135.0 million compared to $169.1 million for the same period in 2008, representing a 20.2% decrease, or $34.1 million. All of our segments experienced a year-over-year revenue decrease as further described below.

Media segment revenue decreased to $63.5 million for the three-month period ended March 31, 2009 compared to $74.7 million for the same period in 2008. The decrease of $11.2 million, or 15.0%, in Media segment revenue was

attributable to a decrease in our lead generation marketing revenue of approximately $12 million, partially offset by an increase in our worldwide display advertising business. We believe the decrease in our lead generation marketing revenue was primarily due to the much weaker macroeconomic environment during the first quarter of 2009 as compared to the same period of the prior year, combined with our experience over the past several quarters that advertisers are cutting budgets in the lead generation channel more aggressively than other online channels. We currently expect our lead generation marketing revenue to decrease further in the second quarter of 2009 due to continued macroeconomic weakness and advertiser budget cuts for this channel.

Affiliate Marketing segment revenue decreased to $28.0 million for the three-month period ended March 31, 2009 compared to $31.2 million in the same period in 2008. This decrease of $3.2 million, or 10.4%, was due to the loss of one significant customer who in-sourced their affiliate marketing program in the second quarter of 2008 and the impact of foreign currency exchange movements.

Comparison Shopping & Search segment revenue decreased to $37.5 million for the three-month period ended March 31, 2009 compared to $57.1 million in the same period in 2008. The decrease of $19.6 million, or 34.3%, was primarily attributable to the significant reduction in consumer purchasing activity that we first began experiencing in our comparison shopping destination websites in the second and third quarters of 2008. The Comparison Shopping & Search segment revenue is concentrated with a limited number of customers. A loss of, or reduction of revenue from, one or more of these customers could have a significant negative impact on the revenue of this segment.

Technology segment revenue was $6.4 million for the three-month period ended March 31, 2009 compared to $7.0 million for the same period in 2008, a decrease of $600,000, or 8.4%. The decrease in revenue was due to: lower average CPM pricing in the three-month period ended March 31, 2009 compared to the same period in 2008, lower volumes of ads served and the impact of foreign currency exchange movements. Technology segment revenue is concentrated with a limited number of customers. A loss of, or reduction of revenue from, one or more of these customers could have a significant negative impact on the revenue of this segment.

Cost of Revenue and Gross Profit. Cost of revenue for the Media and Comparison Shopping & Search segments consists primarily of amounts that we pay to website publishers and distribution partners that are directly related to a revenue-generating event. We pay these entities on a CPC, CPA, CPL or CPM basis. Cost of revenue for all segments also includes labor costs, depreciation on revenue-producing technologies and Internet access costs. Our consolidated cost of revenue was $43.9 million for the three-month period ended March 31, 2009 compared to $51.3 million for the same period in 2008, a decrease of $7.3 million, or 14.3%. Our consolidated gross margin was 67.5% and 69.7% for the three-month periods ended March 31, 2009 and 2008, respectively.

Cost of revenue for the Media segment decreased $3.4 million, or 10.2%, to $29.8 million for the three-month period ended March 31, 2009 compared to $33.1 million for the same period in 2008. Our Media segment gross margin decreased to 53.2% for the three-month period ended March 31, 2009 compared to 55.6% for the same period in 2008. The decrease in Media segment gross margin resulted primarily from a lower mix of promotion-based lead generation revenue, which generates a higher gross margin than a number of other components of Media segment revenue due largely to the classification of certain online advertising costs as sales and marketing expense and not as cost of revenue. These online advertising costs are classified as sales and marketing expense as they are not directly related to a revenue-generating event.

Cost of revenue for the Affiliate Marketing segment decreased $313,000, or 7.5%, to $3.9 million for the three-month period ended March 31, 2009 compared to $4.2 million for the same period in 2008 due to the decrease in revenue. Our Affiliate Marketing gross margin remained relatively flat at 86.1% for the first quarter of 2009 compared to 86.5% for the same period in 2008.

Cost of revenue for the Comparison Shopping & Search segment decreased $4.2 million to $9.6 million for the three-month period ended March 31, 2009 compared to $13.8 million for the same period in 2008 due to the decrease in revenue. Our Comparison Shopping & Search segment gross margin declined slightly to 74.4% for the first quarter of 2009 from 75.8% for the same period in 2008.

Technology segment cost of revenue remained consistent at $900,000 for the three-month periods ended March 31, 2009 and 2008. Our Technology segment gross margin decreased to 85.2% for the three-month period ended March 31, 2009 from 87.6% for the same period in 2008. As the gross margin for the Technology segment is highly dependent upon revenue due to the existing operating leverage, any increases or decreases in segment revenue may have a significant impact on segment gross margin.

Operating Expenses:

Sales and Marketing. Sales and marketing expenses consist primarily of compensation and employee benefits of sales and marketing, network development and related support teams, certain online and offline advertising costs, travel, trade shows, and marketing materials. Online advertising costs included in sales and marketing expenses are comprised primarily of amounts that we pay to website publishers and distribution partners that are not directly associated with a revenue-generating event. Total sales and marketing expenses for the three-month period ended March 31, 2009 were $37.0 million compared to $50.0 million for the same period in 2008, a decrease of $13.0 million, or 26.0%. Sales and marketing expenses decreased primarily due to lower online advertising costs in our lead generation marketing business and our Comparison Shopping & Search segment, as well as lower stock-based compensation as further discussed in the Stock-Based Compensation section below. Our sales and marketing expenses as a percentage of revenue decreased to 27.4% for the three-month period ended March 31, 2009 compared to 29.5% for the same period in 2008, primarily driven by the lower online advertising costs described above.

General and Administrative. General and administrative expenses consist primarily of facilities costs, executive and administrative compensation and employee benefits, depreciation, professional services fees, insurance costs, and other general overhead costs. General and administrative expenses decreased to $16.5 million, or 12.2% of revenue, for the three-month period ended March 31, 2009 compared to $20.9 million, or 12.3% of revenue, for the same period in 2008, a decrease of $4.4 million, or 21.0%. General and administrative expenses decreased primarily due to a decrease of $1.9 million in stock-based compensation and a continued focus on operating expense management in the three-month period ended March 31, 2009.

Technology. Technology expenses include costs associated with the maintenance of our technology platforms, including compensation and employee benefits for our engineering and network operations departments, as well as costs for contracted services and supplies. Technology expenses for the three-month period ended March 31, 2009 were $7.7 million, or 5.7% of revenue, compared to $9.4 million, or 5.6% of revenue, for the same period in 2008, a decrease of $1.8 million, or 18.8%. The decrease in technology expenses was due to a decrease of $245,000 in stock-based compensation and our focus on operating expense management in the three-month period ended March 31, 2009.

Segment Income from Operations. Media segment income from operations for the three-month period ended March 31, 2009 decreased 8.5%, or $1.4 million, to $14.9 million, from $16.3 million in the same period of the prior year, and represented 23.5% and 21.8% of Media segment revenue in these respective periods. The decrease in Media segment income from operations was due principally to a decline in our lead generation marketing revenue, offset partially by an increase in our worldwide display advertising revenue as noted above. The Media segment operating margin increased as a result of the decline in Media's operating expenses.

Affiliate Marketing segment income from operations for the three-month period ended March 31, 2009 decreased 8.4% to $14.4 million, from $15.7 million in the same period of the prior year, and represented 51.5% and 50.4% of Affiliate Marketing segment revenue in these respective periods. The decrease in Affiliate Marketing segment income from operations was due to the lower segment revenue and the increase in operating margin was a result of lower operating expenses.

Comparison Shopping & Search segment income from operations for the three-month period ended March 31, 2009 decreased to $6.8 million from $15.2 million in the same period of the prior year, and represented 18.1% and 26.6% of Comparison Shopping & Search segment revenue in these respective periods. The decrease in income from operations and operating margin was due to lower revenues from a decline in traffic to our comparison shopping destination websites and the negative operating leverage as a result of the lower revenue.

Technology segment income from operations for the three-month period ended March 31, 2009 decreased 17.9% to $2.8 million, from $3.4 million in the same period of the prior year, and represented 43.4% and 48.4% of Technology segment revenue in these respective periods. The decrease in Technology segment income from operations and the lower operating margin were attributable to the decrease in revenue and associated negative operating leverage.

Stock-Based Compensation. Stock-based compensation for the three-month period ended March 31, 2009 was $2.6 million compared to $5.7 million for the same period in 2008. The decrease of $3.1 million was primarily due to stock options repurchased by the Company through a tender offer process completed in the third quarter of 2008. We currently anticipate stock-based compensation in the range of $11 million to $12 million for the year ending December 31, 2009. Such amounts may change as a result of higher or lower than anticipated stock option grants to new and existing employees, differences between actual and estimated forfeitures of stock options, fluctuations in the market value of our common stock, modifications to our existing stock option programs, additions of new stock-based compensation programs, or other factors.

Amortization of Intangible Assets. Amortization of intangible assets for the three-month period ended March 31,

2009 was $6.3 million compared to $7.7 million for the same period in 2008. Certain intangible assets acquired in the acquisitions of Webclients and Fastclick, both acquired in 2005, were fully amortized in the first half of 2008 resulting in decreased amortization expense for the three-month period ended March 31, 2009 compared to the same period in 2008. We currently anticipate amortization expense of approximately $25 million for the year ending December 31, 2009.

Interest Income and Other, Net. Interest income and other, net decreased to a negative $166,000 for the three-month period ended March 31, 2009 compared to a positive $3.0 million for the same period in 2008 due to a decrease in net interest income of $2.3 million and net higher foreign exchange losses related to intercompany receivable balances with certain of our European subsidiaries of $900,000.

Income Tax Expense. For the three-month period ended March 31, 2009, we recorded income tax expense of $10.3 million compared to $13.8 million for the same period in 2008. The increase in the effective income tax rate for the three-month period ended March 31, 2009 to 43.8% from 41.7% in the same period of the prior year was primarily due to a decrease in tax-exempt interest income earned on our marketable securities and the impact of recent tax law changes on . . .
