An investment in our ordinary shares is speculative and involves a high degree of risk. You should carefully consider the following factors as well as the other information contained in this prospectus and in the other reports that we file with the Commission and that we incorporate by reference into this prospectus before deciding to invest in our ordinary shares. This prospectus and statements that we may make from time to time may contain forward-looking information. There can be no assurance that actual results will not differ materially from our expectations, statements or projections. Factors that could cause actual results to differ from our expectations, statements or projections include the risks and uncertainties relating to our business described below.

Acquisitions or investments may be unsuccessful and may divert our management's attention and consume significant resources.

We have made several acquisitions, including the acquisition of Casee in January 2012, Mobile Interactive Group Ltd., or MIG, in November 2011, and Air2Web, Inc., or Air2Web, in October 2011. These, and any future acquisitions that we make, involve numerous risks, any of which could harm our business, including:

We expect that in the future we will evaluate additional acquisitions or make investments in other businesses, or acquire individual products and technologies. Any future acquisition or investment may require us to use significant amounts of cash, issue potentially dilutive equity securities or incur debt.

We may fail to realize some or all of the anticipated benefits of our acquisitions which may adversely affect our financial performance and the value of our ordinary shares.

We continue to integrate our acquired companies, including CASEE, Mobclix, Air2Web, and MIG into our existing operations. These integrations have required and will continue to require significant efforts, including the coordination of future product development and sales and marketing efforts, as well as resources and management's time and efforts. The success of each of these acquisitions will depend, in part, on our ability to realize the anticipated benefits from combining their products and services into ours, and expanding our customer base by increasing the products and services we can provide to our existing and new customers as well as to the customers of the acquired companies. We also must retain key employees from the acquired businesses, as well as retain and motivate our existing executives and other key employees. If we are not able to successfully combine the acquired businesses with our existing operations and integrate our respective operations, technologies and personnel within the anticipated time frame, or at all, the anticipated benefits of the acquisitions may not be realized fully or at all or may take longer to realize than expected and the value of our ordinary shares may be adversely affected. It is possible that the integration process could result in the loss of key employees and other senior management, result in the disruption of our business or adversely affect our ability to maintain relationships with customers, suppliers, distributors and other third parties, or to otherwise achieve the anticipated benefits of each acquisition.

We may need to raise additional capital to grow our business, and we may not be able to raise capital on terms acceptable to us or at all.

The operation of our business and our efforts to grow our business further will require significant cash outlays and commitments, and we may need to borrow additional funds to support our continued growth. We believe that our existing working capital will be sufficient to fund our working capital requirements, capital expenditures and operations for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and it is possible that we could utilize our available financial resources sooner than we currently expect. The timing and amount of our cash needs may vary significantly depending on numerous factors, including but not limited to:

If our existing working capital, is not sufficient to meet our cash requirements, we will need to seek additional capital, potentially through debt, or other equity financings, to fund our growth. We may not be able to raise cash on terms acceptable to us or at all. Financings, if available, may be on terms that are dilutive to our shareholders, and the prices at which new investors would be willing to purchase our securities may be lower than the current price of our ordinary shares. The holders of new securities may also receive rights, preferences or privileges that are senior to those of existing holders of our ordinary shares. If new sources of financing are required but are insufficient or unavailable, we would be required to modify our growth and operating plans to the extent of available funding, which could harm our ability to grow our business.

Our days sales outstanding, or DSOs, may fluctuate significantly from quarter to quarter. Deterioration in DSOs results in a delay in the cash flows we generate from our customers, which could have a material adverse impact on our financial condition and the results of our operations.

The mobile advertising and marketing industry has historically been subject to seasonal fluctuations in demand, with a significant amount of the activity occurring in the second half of the year. In

addition, a significant amount of our business is conducted in emerging markets. Typically payment terms in these regions are longer than payment terms in our other markets. These emerging markets have under-developed legal systems for securing debt and enforcing collection of debt. While we qualify customers that we do business with, their financial positions may change adversely over the longer time period given for payment.

The effect of the seasonality in our business and the longer payment terms, combined with differences in the timing of invoicing and revenue recognition, has in the past and may in the future result in an increase in our DSOs and in our accrued contract receivables. Any increase in our DSOs, or any delay in the conversion of our accrued contract receivables to trade receivables, could have a material adverse impact on our cash flows and working capital, as well as on our financial condition and the results of our operations.

Charges to earnings resulting from acquisitions may adversely affect our operating results.

For any business combination that we consummate, we will recognize the identifiable assets acquired, the liabilities assumed and any non-controlling interest in acquired companies generally at their acquisition date fair values and, in each case, separately from goodwill. Goodwill as of the acquisition date is measured as the excess amount of consideration transferred, which is also generally measured at fair value, and the net of the acquisition date amounts of the identifiable assets acquired and the liabilities assumed. Our estimates of fair value are based upon assumptions believed to be reasonable but which are inherently uncertain. Goodwill is tested for impairment on an annual basis and whenever there is an indication that goodwill may be impaired, relying on a number of factors including operating results, business plans and future cash flows. Impairment occurs when the carrying amount of a cash generating unit including the goodwill, exceeds the estimated recoverable amount of the cash generating unit. The recoverable amount of a cash generating unit is the higher of its fair value less cost to sell and its value-in-use. Value-in-use is the present value of future cash flows expected to be derived from the cash generating unit, based upon a discount rate estimated by management. After we complete an acquisition, the following factors could result in material charges and adversely affect our business, operating results and financial condition and may adversely affect our cash flows:

Substantially all of these costs will be accounted for as expenses that will decrease our net income and earnings per share for the periods in which those costs are incurred. Charges to our operating

results in any given period could differ substantially from other periods based on the timing and size of our future acquisitions and the extent of integration activities.

Our business involves the use, transmission and storage of confidential information, and the failure to properly safeguard such information could result in significant reputational harm and monetary damages.

Our business activities involve the use, transmission, transfer, sharing and storage of information as to which we may have various obligations, including information that may be considered confidential, personal or sensitive, and that may be subject to laws that apply to privacy, data protection and security breaches. Our efforts may not prove to be sufficient to protect the security, integrity and confidentiality of the information we collect and store, and there is no guarantee that inadvertent or unauthorized disclosure will not occur or that third parties will not gain unauthorized access to this information despite our efforts. If such unauthorized disclosure or access does occur, we may be required, under existing and proposed laws or contractual obligations, to notify parties whose information was disclosed or accessed and/or relevant government agencies. We may also be subject to claims of breach of contract or violation of privacy or data protection laws for such disclosure, investigation, penalties or fines by regulatory authorities; and potential claims by parties whose information was disclosed or accessed. The unauthorized disclosure of or access to information may result in the termination of one or more of our commercial relationships and/or a reduction in customer confidence and usage of our services. We may also be subject to litigation alleging the improper collection use, access, transfer, sharing, transmission or storage of confidential information, which could damage our reputation among our current and potential clients, require significant expenditures of capital and other resources and cause us to lose business and revenue.

The global nature of our business subjects us to additional costs and risks that can adversely affect our operating results.

We have offices in multiple countries around the world and we derive a substantial majority of our revenue from, and have a significant portion of our operations outside of the U.S. Compliance with U.S. and foreign country laws and regulations that apply to our international operations increases our cost of doing business. These laws and regulations include U.S. laws such as the Foreign Corrupt Practices Act, and local laws and guidance which also prohibit certain payments to governmental officials and other parties, data protection and security requirements, consumer privacy and protection laws, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions and export requirements. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could result in prohibitions on our ability to offer our products and services in one or more countries, could delay or prevent potential acquisitions and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our business and our operating results. Our success depends, in part, on our ability to anticipate these risks and manage these compliance obligations and potential difficulties. We monitor our international operations and investigate allegations of improprieties relating to transactions and the way in which such transactions are recorded. Where circumstances warrant, we provide information and report our findings to government authorities, but no assurance can be given that action will not be taken by such authorities.

We are also subject to a variety of other risks and challenges in managing an organization operating in various countries, including those related to:

If we are unable to manage the foregoing international aspects of our business, our operating results and overall business will be significantly and adversely affected.

We operate in an industry with extensive intellectual property litigation. Claims of infringement against us may cause our business, financial condition and operating results to suffer.

Our success depends, in part, upon us and our customers not infringing upon intellectual property rights owned by others and being able to resolve claims of intellectual property infringement without major financial expenditures or adverse consequences. The mobile telecommunications industry generally is characterized by extensive intellectual property litigation. Although our technology is relatively new and our industry is rapidly evolving, many participants that own, or claim to own, intellectual property historically have aggressively asserted their rights. For example, we recently were sued in the United States District Court for the District of Delaware by Augme Technologies, Inc. or Augme, alleging infringement of three patents held by Augme. We have also received letters on behalf of certain customers notifying us that the customer had received third party communications alleging that certain applications of the customer infringed the patent rights of the third party, and in turn, alleging that we are obligated to indemnify the customer relating to these matter as the claim allegedly relates to services that we provide to the customer. Each of these matters is in an early stage, and we cannot determine with certainty whether this or any other existing or future third party intellectual property rights would require us to alter our technologies, obtain licenses or cease certain activities.

Future litigation may be necessary to defend ourselves or our customers by determining the scope, enforceability and validity of third party proprietary rights or to establish our proprietary rights. Some of our competitors have substantially greater resources than we do and are able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of time than we could. In addition, patent holding companies that focus solely on extracting royalties and settlements by enforcing patent rights may target us. Regardless of whether claims that we are infringing patents or other intellectual property rights have any merit, these claims are time-consuming and costly to evaluate and defend and could:

In addition to liability for monetary damages against us, which may be trebled and may include attorneys' fees, or, in certain circumstances, our customers, we may be prohibited from developing, commercializing or continuing to provide certain of our mobile marketing services unless we obtain licenses from the holders of the patents or other intellectual property rights. We cannot assure shareholders that we will be able to obtain any such licenses on commercially favorable terms, or at all. If we do not obtain such licenses, our business, operating results and financial condition could be materially adversely affected and we could, for example, be required to cease offering or materially alter our mobile marketing services in some markets.

If we are unable to protect our intellectual property and proprietary rights, our competitive position and our business could be harmed.

We rely primarily on a combination of patent laws, trademark laws, copyright laws, trade secrets, confidentiality procedures and contractual provisions to protect our proprietary technology. As of March 31, 2012, we had five issued patents and 21 pending patent applications on file. However, any future patents that may issue may not survive a legal challenge to their scope, validity or enforceability, or provide significant protection for us. The failure of our patents, or our reliance upon copyright and trade secret laws to adequately protect our technology might make it easier for our competitors to offer similar products or technologies. In addition, patents may not issue from any of our current or any future applications.

Monitoring unauthorized use of our intellectual property is difficult and costly. Our efforts to protect our proprietary rights may not be adequate to prevent misappropriation of our intellectual property. Further, we may not be able to detect unauthorized use of, or take appropriate steps to enforce, our intellectual property rights. Our competitors may also independently develop similar technology. In addition, the laws of many countries, including countries where we conduct business such as China and India, do not protect our proprietary rights to as great an extent as do the laws of European countries and the U.S. Further, the laws in the U.S. and elsewhere change rapidly, and any future changes could adversely affect us and our intellectual property. Any failure by us to meaningfully protect our intellectual property could result in competitors offering products that incorporate our most technologically advanced features, which could seriously reduce demand for our mobile marketing services. In addition, we may in the future need to initiate infringement claims or litigation. Litigation, whether we are a plaintiff or a defendant, can be expensive, time-consuming and may divert the efforts of our technical staff and managerial personnel, which could harm our business, whether or not such litigation results in a determination favorable to us. Further, litigation is inherently uncertain, and thus we may not be able to stop our competitors from infringing upon our intellectual property rights.

We may not be able to enhance our mobile marketing and advertising platform to keep pace with technological and market developments, or to remain competitive against potential new entrants in our markets.

The market for mobile marketing and advertising services is emerging and is characterized by rapid technological change, evolving industry standards, frequent new product introductions and short product life cycles. Our technology platform, Velti mGage, or future solutions we may offer, including technology platforms acquired from Mobclix, Air2Web or MIG, may not be acceptable to marketers and advertisers. To keep pace with technological developments, differentiate ourselves from our competitors, satisfy increasing customer requirements and achieve acceptance of our marketing and advertising campaigns, we will need to enhance our current mobile marketing and advertising solutions and continue to develop and introduce on a timely basis new, innovative mobile marketing and advertising services offering compatibility, enhanced features and functionality on a timely basis at competitive prices. Our inability, for technological or other reasons, to enhance, develop, introduce and deliver compelling mobile marketing services in a timely manner, or at all, in response to changing market conditions, technologies or customer expectations could have a material adverse effect on our

operating results or could result in our mobile marketing and advertising platform becoming obsolete. Our ability to compete successfully will depend in large measure on our ability to maintain a technically skilled development and engineering staff and to adapt to technological changes and advances in the industry, including providing for the continued compatibility of our mobile marketing and advertising platform with evolving industry standards and protocols. In addition, as we believe the mobile marketing market is likely to grow substantially, other companies which are larger and have significantly more capital to invest than us may emerge as competitors. For example, in May 2010, Google, Inc. acquired Admob, Inc.; in January 2010, Apple, Inc. acquired Quattro Wireless, Inc.; in April 2011, Motricity, Inc. acquired Adenyo, Inc.; and Singapore Telecommunications Limited, or SingTel, announced its intention to acquire Amobee, Inc., in March 2012. New entrants could seek to gain market share by introducing new technology or reducing pricing. This may make it more difficult for us to sell our products and services, and could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses or the loss of market share or expected market share, any of which may significantly harm our business, operating results and financial condition.

We do not have multi-year agreements with many of our customers and we may be unable to retain key customers, attract new customers or replace departing customers with customers that can provide comparable revenue.

Our success requires us to maintain and expand our current, and develop new, customer relationships. Most of our contracts with our customers do not obligate them to long-term purchasing of our services. We cannot assure shareholders that our customers will continue to use our products and services or that we will be able to replace, in a timely or effective manner, departing customers with new customers that generate comparable revenue. Further, we cannot assure shareholders that we will continue to generate consistent amounts of revenue over time. Although none of our customers represented 10% or more of our revenues in the year ended December 31, 2011, if a major customer represents a significant portion of our business, the decision by such customer to materially reduce or to cease purchasing our products and services could cause our revenue to be adversely affected. Our failure to develop and sustain long-term relationships with our customers could materially affect our operating results.

Our customer contracts lack uniformity and often are complex, which subjects us to business and other risks.

Our customers include some of the largest wireless carriers and brands which have substantial purchasing power and negotiating leverage. As a result, we typically negotiate contracts on a customer-by-customer basis and our contracts lack uniformity and are often complex. Sometimes short-form insertion orders, purchase orders or work orders are used to document business relationships and these short-form documents may lack some of the protections we might otherwise seek in more detailed forms of contracts. We frequently rely on third parties, such as mobile app publishers, to have the authority to meet their obligations to us, including without limitation the authority to share or transfer consumer data with or to us in compliance with applicable laws and self-regulatory rules and without liability to the consumer or third parties. It is possible that some of these third parties will fail to comply with law or self-regulatory rules, or their own policies or representations, or otherwise expose us to claims as a result of their acts or omissions. Further, we may lack a meaningful ability to be indemnified by some of them in such instances. If we are unable to effectively negotiate, document, enforce and account and bill in an accurate and timely manner for contracts with our key customers or obtain and enforce meaningful indemnities from those with whom we do business, that expose us to risk or liability, our business and operating results may be adversely affected. In addition, we could be unable to timely recognize revenue from contracts that are not managed effectively and this would further adversely impact our financial results.

We have contractual indemnification obligations to most of our customers. If we are required to fulfill our indemnification obligations (e.g. relating to third party content property, claims or operating systems or compliance with laws) that we provide to our customers, we intend to seek indemnification from our suppliers, vendors and content providers to the full extent of their responsibility. Even if the agreement with such supplier, vendor or content provider contains an indemnity provision, it may not cover a particular claim or type of claim or may be limited in amount or scope or the indemnifying party may lack the financial ability or insurance coverage to fulfill their indemnity obligations. As a result, we may not have sufficient indemnification from third parties to cover fully the amounts or types of claims that might be made against us. In addition, we have contractual indemnification obligations to most of our customers relating to the products and services that we provide, including indemnification for infringing technology and compliance with applicable law and self-regulatory rules, and we may have an obligation to our customers for damages under these indemnification provisions. Any significant indemnification obligation to our customers could have a material adverse effect on our business, operating results and financial condition.

Our sales efforts require significant time, expense and effort and could hinder our ability to expand our customer base and increase revenue.

Attracting new customers requires substantial time and expense and we cannot assure that we will be successful in establishing new relationships, or maintaining or advancing our current relationships. For example, it may be difficult to identify, engage and market to customers who do not currently perform mobile marketing or advertising or are unfamiliar with our current services or platform. Further, many of our customers typically require input from one or more internal levels of approval. As a result, during our sales effort, we must identify multiple people involved in the purchasing decision and devote a sufficient amount of time to presenting our products and services to those individuals. The newness and complexity of our services, and the flexibility of our pricing model, often requires us to spend substantial time and effort assisting potential customers in evaluating our products and services including providing demonstrations and benchmarking against other available technologies. This process can be costly and time consuming. We expect that our sales process will become less burdensome as our products and services become more widely known and used. However, if this change does not occur, we will not be able to expand our sales effort as quickly as anticipated and our sales will be adversely affected.

Our services are provided on mobile communications networks that are owned and operated by third parties who we do not control and the failure or security breach of any of these networks would adversely affect our ability to deliver our services to our customers.

Our mobile marketing and advertising platform is partially dependent on the reliability of mobile operators who maintain sophisticated and complex mobile networks. Such mobile networks have historically, and particularly in recent years, been subject to both rapid growth and technological change. If the network of a mobile operator with which we are integrated should fail, including because of new technology incompatibility, the degradation of network performance under the strain of increased mobile consumer use, or a general failure from natural disaster or political or regulatory shut-down, we will not be able provide our services to our customers through such mobile network. Should data that resides on or is transmitted over the network be breached, there may also be limitations on our providing such services. These events, in turn, could impair our reputation and business, potentially resulting in a material, adverse effect on our financial results.

If our mobile marketing and advertising services platform does not scale as anticipated, our business will be harmed.

We must be able to continue to scale to support potential ongoing substantial increases in the number of users in our actual commercial environment, and maintain a stable service infrastructure and reliable service delivery for our mobile marketing and advertising solutions. In addition, we must continue to expand our service infrastructure to handle growth in customers and usage. If our mobile marketing and advertising platform, Velti mGage, and the technology platforms acquired from Mobclix, Air2Web and MIG, do not efficiently and effectively scale to support and manage a substantial increase in the number of users while maintaining a high level of performance, the quality of our services could decline and our business will be seriously harmed. In addition, if we are unable to secure data center space with appropriate power, cooling and bandwidth capacity, we may not be able to efficiently and effectively scale our business to manage the addition of new customers and overall mobile marketing and advertising solutions provided to our customers.

The success of our business depends, in part, on wireless carriers continuing to accept our customers' messages for delivery to their subscriber base.

In a portion of our business we depend on wireless carriers to deliver our customers' messages to their subscriber base. Wireless carriers often impose standards of conduct or practice that significantly exceed current legal requirements and potentially classify our messages as "spam," even where we do not agree with that conclusion. In addition, the wireless carriers use technical and other measures to attempt to block non-compliant senders from transmitting messages to their customers; for example, wireless carriers block short codes or Internet Protocol addresses associated with those senders. There can be no guarantee that we, or short codes registered to us, will not be blocked or blacklisted or that we will be able to successfully remove ourselves from those lists. Although our services typically require customers to opt-in to a campaign, minimizing the risk that our customers' messages will be characterized as spam, blocking of this type could interfere with our ability to market products and services of our customers and communicate with end users and could undermine the effectiveness of our customers' marketing campaigns. To date we have not experienced any material blocking of our messages by wireless carriers, but any such blocking could have an adverse effect on our business and results of operations.

Many of our customers require us to maintain specified levels of service commitments and failure to meet these levels would both adversely impact our customer relationship as well as our overall business.

Many of our customers require us to contractually commit to maintain specified levels of customer service under agreements commonly referred to as service level agreements. In particular, because of the importance that mobile consumers in general attach to the reliability of a mobile network, mobile operators are especially known for their rigorous service level requirements. We are a rapidly growing company and, although to date we have not experienced any significant interruption of service, if we were to be unable to meet our contractually committed service level obligations, we would both be subject to fees, penalties, civil liability as well as adverse reputational consequences. To date we have not had to pay any material penalties for failure to meet service level commitments. We recognize these penalties, if and when incurred, as a reduction to revenue. These in turn would materially harm our business and operating results.

Some of our programs are partially supported by government grants, which may be reduced, withdrawn, delayed or reclaimed.

We have received grants from European Union programs administered by the Government of Greece in order to aid our technology development efforts, and have been approved for an additional grant. The first of these grants was for a total of approximately $4.5 million that has been paid in full

to us. The second grant is for a total of approximately $8.5 million. That has also been paid in full. In 2009, we applied for a third grant and received acceptance of eligibility for up to an additional $12.0 million over four years. In 2011, we also applied for a fourth grant and we are expecting to receive acceptance of eligibility for up to an additional $4.8 million over three years. Under the terms of these grants, we are required to list these grants under a separate, specific reserve account on our balance sheets that we maintain for our Greek subsidiary under generally accepted accounting principles in Greece. If we fail to maintain this accounting treatment for five years following the final disbursement by the Greek government under each respective grant, we will be required to refund the entire amount of such grant. If we fail to maintain this accounting treatment between the fifth and tenth anniversaries of receiving the final disbursement under each grant, we will be required to pay a tax penalty. We have to date been in compliance with this requirement and do not anticipate being unable to remain in compliance for the duration of the requirement. However, in the event that we are unable to remain in compliance, a payment of refund or tax penalty would adversely affect our operating results. Further, were the Government of Greece to abrogate its commitment to provide the final disbursement of funds for the last two grants, our development efforts and ability to meet our timing expectations for new marketing and advertising services would be adversely affected.

We operate in an emerging technology market and have experienced, and may continue to experience, significant growth in our business. If we do not effectively manage our growth, the quality of our products and services may suffer, which could negatively affect our brand and operating results. Our growth has placed, and is expected to continue to place, a significant strain on our managerial, administrative, operational and financial resources and our infrastructure. Our future success will depend, in part, upon the ability of our senior management to manage growth effectively. This will require us to, among other things:

Moreover, as our sales increase, we may be required to concurrently deploy our services infrastructure at multiple additional locations or provide increased levels of customization. As a result, we may lack the resources to deploy our services on a timely and cost-effective basis. Failure to accomplish any of these requirements would seriously harm our ability to deliver our mobile marketing and advertising platform in a timely fashion, fulfill existing customer commitments or attract and retain new customers.

We may be required to reduce our prices to compete successfully, or we may incur increased or unexpected costs, which could have a material adverse effect on our operating results and financial condition.

The intensely competitive market in which we conduct our business may require us to reduce our prices, which could negatively impact our operating results. Our market is highly fragmented with numerous companies providing one or more competitive offerings to our marketing and advertising platform. New entrants seeking to gain market share by introducing new technology, products or

services may make it more difficult for us to sell our products and services, and could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses or the loss of market share or expected market share, any of which may significantly harm our business, operating results and financial condition.

Moreover, we may experience cost increases or unexpected costs which may also negatively impact our operating results, including increased or unexpected costs related to:

Any unanticipated costs associated with the foregoing items would have a material adverse effect on our business, operating results and financial condition.

Mergers or other strategic transactions by our competitors or mobile operator partners could weaken our competitive position or reduce our revenue.

If two or more of our competitors were to merge or partner, the change in the competitive landscape could adversely affect our ability to compete effectively. In addition, consolidation could result in new, larger entrants in the market. For example, in May 2010, Google, Inc. acquired Admob, Inc.; in January 2010, Apple, Inc. acquired Quattro Wireless, Inc.; in April 2011, Motricity, Inc. acquired Adenyo, Inc.; and Singapore Telecommunications Limited, or SingTel, announced its intention to acquire Amobee, Inc. in March 2012. Although none of these companies directly compete with our full range of services, the transactions are indicative of the level of interest among potential acquirers in the mobile marketing and advertising industry. Our direct competitors may also establish or strengthen co-operative relationships with their mobile operator partners, sales channel partners or other parties with whom we have strategic relationships, thereby limiting our ability to promote our products and services. Disruptions in our business caused by these events could reduce revenue and adversely affect our business, operating results and financial condition.

The mobile advertising or marketing market may deteriorate or develop more slowly than expected, any of which could harm our business.

If the market for mobile marketing and advertising deteriorates, or develops more slowly than we expect, our business could suffer. Our future success is highly dependent on an increase in the use of mobile communications, the commitment of advertisers and marketers to mobile communications as an advertising and marketing medium, the willingness of our potential clients to outsource their mobile advertising and marketing needs, and our ability to sell our services to advertising agencies and brands. The mobile advertising and marketing market is relatively new and rapidly evolving. As a result, future demand and market acceptance for mobile marketing and advertising is uncertain. Many of our current or potential clients 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 continue to allocate more funds in the future, if any. Also, we must compete with traditional advertising media, including television, print, radio and outdoor advertising, for a share of our clients' total advertising budgets.

Businesses, including current and potential clients, 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, and therefore the market for mobile marketing and advertising may deteriorate or develop more slowly than expected, or may develop using technology or functionality that we did not anticipate and may be unable to meet effectively and timely. Our current or potential customers may lose interest in our current or future solutions, or find that such solutions do not provide the benefits anticipated. These challenges could significantly undermine the commercial viability of mobile advertising and marketing and seriously harm our business, operating results and financial condition.

If we fail to detect click fraud or other invalid clicks on ads, we could lose the confidence of our advertiser clients, which would cause our business to suffer.

Our Exchange business relies on delivering positive results to our advertiser clients. We are exposed to the risk of fraudulent and other invalid clicks or conversions that advertisers may perceive as undesirable. Because of their smaller sizes as compared to personal computers, mobile device usage could result in a higher rate of accidental or otherwise inadvertent clicks by a user. Invalid clicks could also result from click fraud, where a mobile device user intentionally clicks on ads for reasons other than to access the underlying content of the ads. If fraudulent or other malicious activity is perpetrated by others, and we are unable to detect and prevent it, the affected advertisers may experience or perceive a reduced return on their investment. High levels of invalid click activity could lead to dissatisfaction with our advertising services, refusals to pay, refund demands or withdrawal of future business. Any of these occurrences could damage our brand and lead to a loss of advertisers and revenue.

Our business depends on our ability to collect, share, transfer, store, transmit and use data, and any limitation on our ability to collect, share, transfer, store, transmit and use this data could significantly diminish the value of our services and cause us to lose customers and revenue.

In our provision of mobile marketing and advertising services, we often collect or receive from publishers, advertisers and others, information about the mobile device user, including without limitation, interaction of the mobile device user with the content delivered, such as whether the user visited a landing page or watched a video. We may also be able to collect, or may be delivered, information about the user's mobile location and other information. As we collect and aggregate this data, including data provided by billions of ad impressions, we analyze it in order to optimize the services that we provide to customers.

The tracking of persistent and other identifiers, such as device identifiers, is important to our ability to optimize content and ad delivery and to track downloads and conversions and this ability is highly valued by our customers. The degree to which we will be able to continue doing so in compliance with third party carrier and platform rules and applicable laws and regulations may change.

Furthermore, even absent legal requirements, our customers and others in the mobile ecosystem might decide not to allow us to collect some or all of the data with respect to which we currently have access or might limit our use of this data. Any limitation on our ability to collect, share, transfer, store, transmit and use data about user behavior and interaction with mobile device content could make it more difficult for us to deliver effective mobile advertising and marketing programs that meet the demands of our customers and this could hurt our business. In addition, consumer advocacy groups and class action plaintiffs' lawyers are pursuing an array of theories challenging online and mobile behavioral advertising, as well as tracking of user behavior even without targeting of ads based thereon. If we become subject to such litigation the cost of defending such actions, and the potential of costly settlements or adverse judgments, could have a material negative impact on our business.

Interruptions, failures or defects in our data collection, mining, analysis and storage systems, as well as privacy, data protection and security concerns and regulatory restrictions regarding the collection, sharing, transfer, storage and use of consumer data, could also limit our ability to aggregate and analyze mobile device user data from our customers' marketing and advertising campaigns. If that happens, we may not be able to optimize our services for the benefit of our customers, which could make our services less valuable, and, as a result, we may lose customers and our revenue may decline.

Mobile connected device users may choose not to allow marketing or advertising on their devices.

The success of our business model depends on our ability to deliver content to consumers on their mobile connected devices. Targeted delivery is done primarily through analysis of data, much of which is collected on the basis of third parties such as mobile app publishers obtaining user-provided permissions. Users may elect not to allow data sharing for a number of reasons, such as privacy and security concerns. Third parties we rely on may elect to discontinue providing us data about their users as a result of users' concerns, or otherwise. Further, third parties we rely on, such as app publishers, might provide us data in a manner that is inconsistent with what they represented to their users or with applicable law and we could get brought into claims or controversies related thereto. In addition, the designers of mobile device operating systems are increasingly promoting features that allow device users to disable some of the functionality that facilitates tracking and targeting and content delivery, which may impair or disable our services on their devices, and device manufacturers may include these features as part of their standard device specifications. Companies may develop products that enable users to prevent ads from appearing on their mobile device screens. If any of these developments were to occur, our ability to deliver effective mobile advertising campaigns on behalf of our customers would suffer, which could adversely impact our operating results.

Our earnings may be adversely affected by fluctuations in foreign currency values.

The majority of the value of our revenue transactions is conducted using the euro, while the remaining is conducted using the U.S. dollar and currencies of other countries, and we incur costs in euro, British pound sterling, the U.S. dollar and other local currencies. Changes in the relative value of major currencies, particularly the U.S. dollar, euro and British pound sterling, can significantly affect revenue and our operating results. In 2010, approximately 77% of our revenue was payable in euros, and in 2011, approximately 66% of our revenue was payable in euros, although we expect this concentration to continue to decrease over time as the percentage of our U.S. dollar denominated revenue grows. This will likely result in euros comprising a smaller percentage of our revenue as we continue to increase sales to customers in geographies outside of Europe, with revenue payable in U.S. dollars or other currencies, as well as increase the number of contracts with European customers with revenue payable in U.S. dollars. As a majority of our costs and expenses are incurred in euros, any devaluation of the euro will positively impact our financial statements as reported in U.S. dollars, and any decline in the value of the dollar compared to the euro will result in foreign currency translation costs incurred by us. Unless the euro materially fluctuates, however, we do not expect fluctuations of the euro to have a material adverse effect on our results of operations or financial condition and the recent devaluation of the euro has not materially adversely impacted our financial results. Our foreign currency transaction gains and losses are charged against earnings in the period incurred. We currently do not enter into foreign exchange forward contracts to hedge certain transactions in major currencies and even if we wished to do so in the future, we may not be able, or it may not be cost-effective, to enter into contracts to hedge our foreign currency exposure.

Because of our revenue recognition policies, revenue may not be recognized in the period in which we contract with a customer, and downturns or upturns in sales may not be reflected in our operating results until future periods.

Our SaaS revenue consists of usage-based fees recognized ratably over the period of the agreement and performance-based fees recognized as transactions are completed, specific quantitative goals are met or a performance milestone is achieved. As a result, we may be unable to rapidly increase our revenue through additional sales in any period, as revenue for performance-based fees will only be recognized if and when quantitative goals are met or a milestone is achieved. Revenue from our managed service arrangements is recognized either as the services are rendered for our time and material contracts or, for fixed price contracts, ratably over the term of the contract when accepted by the customer. Our license and software revenue is recognized when the license is delivered and on a percentage of completion basis for our services to customize and implement a specific software solution.

Because of these accounting policies, revenue generated during any period may result from agreements entered into during a previous period. A reduction in sales in any period therefore may not significantly reduce our revenue for that period, but could negatively affect revenue in future periods. In addition, since operating costs are generally recognized as incurred, we may be unable to quickly adjust our cost structure to match the impact of the reduction in revenue in future periods. Accordingly, the effect of significant downturns in our sales may not be fully reflected in our results of operations until future periods.

Our geographically dispersed and historically rapidly growing business involves inherently complex accounting which if we fail to manage efficiently could adversely impact our financial reporting and business.

Since our inception, we have operated campaigns or provided marketing or advertising solutions to customers in over 50 countries and we have offices in multiple countries and we continue to expand our operations geographically. We must maintain internal accounting systems to quickly and accurately track our financial performance, including our complex revenue transactions. If we are unable to efficiently manage our accounting systems, our financial results could be materially misstated which in turn would impact both our financial reporting as well as have adverse reputational effects on our business.

We depend on the services of key personnel to implement our strategy. If we lose the services of our key personnel or are unable to attract and retain other qualified personnel, we may be unable to implement our strategy.

We believe that the future success of our business depends on the services of a number of key management and operating personnel, including Alex Moukas, our chief executive officer, Chris Kaskavelis, our chief operating officer, Sally J. Rau, our chief administrative officer, general counsel and corporate secretary, Menelaos Scouloudis, our chief commercial officer, and Wilson W. Cheung, our chief financial officer. We have at-will employment relationships with all of our management and other employees, and we do not maintain any key-person life insurance policies. Some of these key employees have strong relationships with our customers and our business may be harmed if these employees leave us. The loss of members of our key management and certain other members of our operating personnel could materially adversely affect our business, operating results and financial condition.

In addition, our ability to manage our growth depends, in part, on our ability to identify, hire and retain additional qualified employees, including a technically skilled development and engineering staff. We face intense competition for qualified individuals from numerous technology, marketing and mobile software and service companies. Competition for qualified personnel is particularly intense in many of

the large, international metropolitan markets in which we have offices, including for example, London, New York and San Francisco. We require a mix of highly talented engineers as well as individuals in sales and support who are familiar with the marketing and advertising industry. In addition, new hires in sales positions require significant training and may, in some cases, take more than a year before they achieve full productivity. Our recent sales force hires and planned hires may not become as productive as we would like, and we may be unable to hire sufficient numbers of qualified individuals in the future in the markets where we do business. Further, given the rapid pace of our expansion to date, we may be unable to attract and retain suitably qualified individuals who are capable of meeting our growing, creative, operational and managerial requirements, or may be required to pay increased compensation in order to do so. If we are unsuccessful in attracting and retaining these key personnel, our ability to operate our business effectively would be negatively impacted and our business, operating results and financial condition would be adversely affected.

Activities of our customers and others in the mobile ecosystem we deal with could damage our reputation or give rise to legal claims against us.

The products, services and activities of our customers and others in the mobile ecosystem may not comply with federal, state and local laws, including, but not limited to, laws and regulations relating to mobile communications, privacy and/or data protection. Failure of these parties to comply with applicable laws or our policies or contract terms could damage our reputation and adversely affect our business, operating results or financial condition. We cannot predict whether our role in facilitating our customers' marketing or advertising activities would expose us to liability under these laws. Any claims made against us could be costly and time-consuming to defend. If we are exposed to this kind of liability, we could be required to pay substantial fines or penalties, redesign our business methods, discontinue some of our services or otherwise expend resources to avoid liability.

We may potentially be subject to claims by third parties for content in the advertising we deliver on behalf of our customers if the music, artwork, text or other content involved violates the patent, copyright, trademark or other intellectual property rights of such third parties or if the content is defamatory, deceptive or otherwise violates applicable laws or regulations. Any claims or counterclaims could be time consuming, result in costly litigation or divert management's attention.

Software and components that we incorporate into our mobile marketing services may contain errors or defects, which could have an adverse effect on our business.

We use a combination of custom and third party software, including open source software, in building our mobile marketing and advertising platform. Although we test certain software before incorporating it into our platform, we cannot guarantee that all of the third party technology that we incorporate will not contain errors, defects or bugs. We continue to launch enhancements to Velti mGage, our integrated end-to-end mobile marketing and advertising platform, and we cannot guarantee any such enhancements will be free from errors, defects or bugs. If errors or defects occur in products and services that we utilize in our mobile marketing and advertising platform, it could result in damage to our reputation, lost revenue and diverted development resources.

Our use of open source software could limit our ability to provide our platform to our customers.

We have incorporated open source software into our platform. Although we closely monitor our use of open source software, the terms of many open source licenses to which we are subject have not been interpreted by U.S. or foreign courts, and there is a risk that such licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to provide our platform to our customers. We may also face claims regarding ownership of, or demanding release of, source code, open source software and/or derivative works that were developed using such open source software. These claims could result in litigation, our could require us to seek licenses from third parties in order

to continue offering our platform, to re-engineer our platform or discontinue use of portions of the functionality provided by our platform, any of which could have a material adverse effect on our business, operating results or financial condition.

We use data centers to deliver our platform and services. Any disruption of service or data breach at these facilities could harm our business.

We host our services and serve all of our customers from data center facilities located around the world, including in the U.K., India, China, the U.S., Russia and Greece. We also host a number of services via a vendor, such as the Amazon Web Services. We do not control the operations at these third party facilities. All of these facilities are vulnerable to damage or interruption from earthquakes, hurricanes, floods, fires, terrorist attacks, hackers, security failures, data breaches, power losses, telecommunications failures and similar events. They also could be subject to physical or electronic break-ins, computer viruses, denial of service attacks, sabotage, intentional acts of vandalism and other misconduct. The occurrence of a natural disaster or an act of terrorism, a decision to close the third party facilities without adequate notice or other unanticipated problems could result in lengthy interruptions in our services or the loss or compromise of data. Although we maintain off-site tape backups of our customers' data, we do not currently operate or maintain a backup data center for any of our services, which increases our vulnerability to interruptions or delays in our service or the loss or compromise of data. Interruptions in our services or data compromise or loss might harm our reputation, reduce our revenue, cause us to incur financial penalties, subject us to potential liability and cause customers to terminate their contracts.

We may have future exposure to greater than anticipated tax liabilities, and we could owe significant taxes even during periods when we experience low operating profit or operating losses.

Our future income taxes could be adversely affected by earnings being lower than anticipated in jurisdictions where we have lower statutory tax rates and higher than anticipated in jurisdictions where we have higher statutory tax rates, by changes in the valuation of our deferred tax assets and liabilities or changes in tax laws, regulations, accounting principles or interpretations thereof. We cannot assure shareholders that we would not be impacted by changes in Jersey or Irish tax laws and that such changes would not materially impact our effective tax rates. Ireland, where we are tax resident, continues to review certain of its tax provisions, and there have been some concerns that Ireland's 12.5% corporate tax rate could rise as a result of recent economic and budgetary issues facing the Irish government. Any increase in the Irish corporate tax rate, if adopted, could have an adverse impact on our financial results. In addition, there is a risk that amounts paid or received under arrangements between our various international subsidiaries in the past and/or the future could be deemed for transfer tax purposes to be lower or higher than we previously recognized or expected to recognize. Our determination of our tax liability is always subject to review by applicable tax authorities. Any adverse outcome of such a review could have a negative effect on our operating results and financial condition. In addition, the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment, and there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made. Certain combinations of these factors could cause us to owe significant taxes even during period when we experience low income before taxes or loss before taxes.

If we were classified as a passive foreign investment company, there would be adverse tax consequences to U.S. holders of our ordinary shares.

If we were classified as a "passive foreign investment company" or "PFIC" under section 1297 of the Internal Revenue Code, of 1986, as amended, or the Code, for any taxable year during which a U.S. holder holds ordinary shares, such U.S. holder generally would be taxed at ordinary income tax rates on any gain realized on the sale or exchange of the ordinary shares and on any "excess distributions" (including constructive distributions) received on the ordinary shares. Such U.S. holder could also be subject to a special interest charge with respect to any such gain or excess distribution.

We would be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which either (i) at least 75% of our gross income is passive income or (ii) on average, the percentage of our assets that produce passive income or are held for the production of passive income is at least 50% (determined on an average gross value basis). We were not classified as a PFIC for fiscal year 2011 or in any prior taxable year. Whether we will, in fact, be classified as a PFIC for any subsequent taxable year depends on our assets and income over the course of the relevant taxable year and, as a result, cannot be predicted with certainty. In particular, because the total value of our assets for purposes of the asset test will be calculated based upon the market price of our ordinary shares, a significant and sustained decline in the market price of our ordinary shares and corresponding market capitalization relative to our passive assets could result in our being classified as a PFIC. There can be no assurance that we will not be classified as a PFIC in the future or the Internal Revenue Service will not challenge our determination concerning PFIC status for any prior period.

Continuing unfavorable global economic conditions could have a material adverse effect on our business, operating results and financial condition.

Unfavorable economic conditions in the financial and credit markets in the U.S., Europe and Asia has led to a global economic slowdown, with the economies of the U.S. and Europe showing continued signs of weakness. If these economies weaken further or fail to improve, our customers may reduce or postpone their marketing and advertising spending, which could materially adversely affect our business, operating results and financial condition.

Changes in the wireless communications industry may adversely affect our business.

The wireless communications industry may experience significant growth and change which could adversely affect our business. Technologies such as 4G mobile broadband, Wi-Fi, worldwide interoperability for microwave access, or WiMAX, and voice over Internet protocol, or VOIP, are challenging existing wireless communication technologies. We believe we will be able to adapt to future technological changes; however, in order to do so, we may require significant investment in and time and effort in order to keep pace with such technological innovation. This could have an adverse effect on our business, operating results and financial condition.

Our business practices with respect to data could give rise to liabilities or reputational harm as a result of governmental regulation, legal requirements or industry standards relating to consumer privacy and data protection.

In the course of providing our services, we collect, share, transfer, use, transmit and store information related to mobile devices and their users, including sometimes a device's geographic location, for the purpose of delivering targeted lads to the user of the device. Federal, state and foreign laws and regulations govern the collection, use, retention, sharing and security of data, including personal data that we collect across our mobile marketing and advertising platform. We strive to comply with all applicable laws, regulations, policies and legal obligations relating to privacy and data

protection. However, it is possible that these requirements may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and/or may conflict with other rules or our practices. For example, our subsidiaries, Velti USA, Inc. and Velti North America, Inc., were recently named as defendants in a nationwide class action in the United States District Court for the Northern District of California alleging that the defendants distributed unauthorized SMS messages in violation of the federal Telephone Consumer Protection Act, 47 U.S.C. section 227. Furthermore, consumer data tracking and targeting is a developing business and the laws relating to it are also developing. It is unclear how existing laws that were passed before these practices and related technologies will be applied to us or what new laws and regulations may be passed. Any failure, or perceived failure, by us to comply with applicable U.S. federal, state, or laws in any other countries including laws and regulations regulating privacy, data protection or consumer privacy, could result in proceedings or actions against us by governmental entities or others.

The regulatory framework for privacy issues worldwide is evolving, and various government and consumer agencies and public advocacy groups have called for new regulation and changes in industry practices, including some directed at the mobile industry in particular. It is possible that new laws and regulations will be adopted in the United States and/or in other countries, or existing laws and regulations may be interpreted in new ways, that would affect our business, particularly with regard to location-based services and collection, sharing or use of data to track users and/or target ads and communication with consumers via mobile devices.

The U.S. government, including the Federal Trade Commission and the Department of Commerce, has announced that it is reviewing the need for greater regulation of the collection of consumer information, including regulation aimed at restricting some targeted advertising practices. The Federal Trade Commission has also proposed revisions to the Children's Online Privacy Protection Act, or COPPA, that could, if adopted, create greater compliance burdens on us and/or third parties we work with (e.g. publishers). In addition states may pass new laws or interpret existing laws that could create burdens on mobile advertising providers.

As we expand our operations globally, compliance with regulations that differ from country to country may also impose substantial burdens on our business. In particular, the European Union has traditionally taken a broader view as to what is considered personal information (e.g. device identifiers) and has imposed greater obligations under data protection laws and regulations. In addition, individual EU member countries and/or their regulatory bodies, including data protections authorities, have had discretion with respect to their interpretation and implementation of the regulations, which has resulted in variation of privacy standards from country to country. New EU proposals, if implemented, may result in a greater compliance burden if we deliver ads to mobile device users in Europe. Complying with any new regulatory requirements could force us to incur substantial costs or require us to change our business practices in a manner that could compromise our ability to effectively pursue our growth strategy.

In addition to compliance with government regulations, we voluntarily participate in several trade associations and industry self-regulatory groups that promulgate best practices or codes of conduct addressing the provision of location-based services, delivery of promotional content to mobile devices, and tracking of device users or devices for the purpose of delivering targeted advertising. We comply with wireless carrier technological and other requirements for access to their customer's mobile devices. We could be adversely affected by changes to these guidelines and codes in ways that are inconsistent with our practices or in conflict with the laws and regulations of U.S. or international regulatory authorities.

Changes in government regulation of the wireless communications industry may adversely affect our business.

Depending on the products and services that they offer, mobile data service providers are or may be subject to regulations and laws applicable to providers of mobile, Internet and VOIP services both domestically and internationally. In addition, the application of existing domestic and international laws and regulations relating to issues such as user privacy and data protection, defamation, pricing, advertising, taxation, gambling, sweepstakes, promotions, billing, real estate, consumer protection, accessibility, content regulation, quality of services, telecommunications, mobile, television and intellectual property ownership and infringement to wireless industry providers and platforms in many instances is unclear or unsettled. Further, the application to us of existing laws regulating or requiring licenses for certain businesses of our advertisers can be unclear.

It is possible that a number of laws and regulations may be adopted in the countries where we operate that may be inconsistent and that could restrict the wireless communications industry, including laws and regulations regarding lawful interception of personal data, taxation, content suitability, content marketing and advertising, copyright, distribution and antitrust. Furthermore, the growth and development of the market for electronic storage of personal information may prompt calls for more stringent consumer protection laws that may impose additional burdens, including costs on companies such as ours that store personal information. We anticipate that regulation of our industry will increase and that we will be required to devote legal and other resources to address this regulation. Changes in current laws or regulations or the imposition of new laws and regulations regarding the media and wireless communications industries may lessen the growth of wireless communications services and may materially reduce our ability to increase or maintain sales of our mobile marketing services. We may incur substantial liabilities for expenses necessary to investigate or defend such litigation or to comply with these laws and regulations, as well as potential substantial penalties for any failure to comply. Compliance with these laws and regulations may also cause us to change or limit our business practices in a manner adverse to our business.

A number of studies have examined the health effects of mobile device use, and the results of some of the studies have been interpreted as evidence that mobile device use causes adverse health effects. The establishment of a link between the use of mobile devices and health problems, or any media reports suggesting such a link, could increase government regulation of, and reduce demand for, mobile devices and, accordingly, the demand for our mobile marketing services, which could harm our business, operating results and financial condition.

The gathering, transmission, storage and sharing or use of consumer data could give rise to liabilities or additional costs of operation as a result of governmental regulation, legal requirements, civil actions or differing views of personal privacy rights.

We collect, use, transfer, share, transmit and store a large volume of consumer data, including personal information, in the course of providing our services. Federal, state and foreign laws and regulations govern the collection, use, retention, sharing and security of data that we receive from our customers, their users and third parties. Any failure, or perceived failure, by us to comply with applicable U.S. federal, state, European Union or other international privacy, data protection or consumer protection-related laws, regulations or industry self-regulatory principles could result in proceedings or actions against us by governmental entities or others, which could potentially have an adverse effect on our business, operating results and financial condition. Additionally, we may also be contractually liable to indemnify and hold harmless our customers or others from the costs or consequences of inadvertent or unauthorized collection, use or disclosure of their customers' personal data which we store or handle as part of providing our services or otherwise relating to our data practices.

The interpretation and application of privacy, data protection and data retention laws and regulations are currently unsettled in the U.S. and internationally, particularly with regard to location-based services, use of customer data to track users and/or target advertisements and communication with consumers via mobile devices. New laws such as the newly proposed European Data Protection Regulation have been proposed in various locations, further restricting the right to use personal data. Such laws may be interpreted and applied inconsistently from country to country and inconsistently with our current data protection policies and practices. Complying with these varying international requirements could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business, operating results or financial condition.

As privacy and data protection have become more sensitive issues, we may also become exposed to potential liabilities as a result of differing views on the privacy of personal information. These and other privacy concerns, including security breaches, could adversely impact our business, operating results and financial condition.

Our ordinary shares are issued under the laws of Jersey, which may not provide the level of legal certainty and transparency afforded by incorporation in a U.S. state.

We are organized under the laws of the Bailiwick of Jersey, a British crown dependency that is an island located off the coast of Normandy, France. Jersey is not a member of the European Union. Jersey legislation regarding companies is largely based on English corporate law principles. However, there can be no assurance that Jersey law will not change in the future or that it will serve to protect investors in a similar fashion afforded under corporate law principles in the U.S., which could adversely affect the rights of investors.

A change in our tax residence could have a negative effect on our future profitability.

Although we are organized under the laws of Jersey, we are resident in Ireland for Irish and Jersey tax purposes. It is possible that in the future, whether as a result of a change in law or the practice of any relevant tax authority or as a result of any change in the conduct of our affairs following a review by our directors or for any other reason, we could become, or be regarded as having become, a resident in a jurisdiction other than Ireland. Should we cease to be an Irish tax resident, we may be subject to a charge to Irish capital gains tax on our assets and to unexpected tax charges in other jurisdictions on our income or net profit. Similarly, if the tax residency of any of our subsidiaries were to change from their current jurisdiction for any of the reasons listed above, we may be subject to a charge to local capital gains tax on the assets.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses.

We are a "foreign private issuer," as such term is defined in Rule 405 under the Securities Act, and therefore, we are not required to comply with all the periodic disclosure and current reporting requirements of the U.S. Securities Exchange Act of 1934, as amended, and related rules and regulations. Under Rule 405, the determination of foreign private issuer status is made annually on the last business day of an issuer's most recently completed second fiscal quarter and, accordingly, our most recent determination was made on June 30, 2011. We expect that we will continue to be a foreign private issuer as of June 30, 2012.

In the future, we would lose our foreign private issuer status if a majority of our shareholders and a majority of our directors or management are U.S. citizens or residents. If we were to lose our foreign private issuer status, we would have to mandatorily comply with U.S. federal proxy requirements, and our officers, directors and principal shareholders would become subject to the short-swing profit

disclosure and recovery provisions of Section 16 of the Exchange Act. We would also be required to file periodic reports and registration statements on U.S. domestic issuer forms with the U.S. Securities and Exchange Commission, or SEC, which are more detailed and extensive than the forms available to a foreign private issuer. As a result, the regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly higher. We may also be required to modify certain of our policies to comply with good governance practices associated with U.S. domestic issuers. Such conversion and modifications will involve additional costs.

U.S. shareholders may not be able to enforce civil liabilities against us.

A number of our directors and executive officers and a number of directors of each of our subsidiaries are not residents of the U.S., and all or a substantial portion of the assets of such persons are located outside the U.S. As a result, it may not be possible for investors to effect service of process within the U.S. upon such persons or to enforce against them judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the U.S. We have been advised by our Jersey solicitors that there is doubt as to the enforceability in Jersey of original actions, or in actions for enforcement of judgments of U.S. courts, of civil liabilities to the extent predicated upon the federal and state securities laws of the U.S.

The following table sets forth our current portion of long-term debt and capitalization as of March 31, 2012.

We are registering 1,389,841 ordinary shares issued to the selling shareholders to permit the resale of such ordinary shares by the selling shareholders and their permitted assignees, transferees, donees, or other successors-in-interest of the ordinary shares from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling shareholders of the ordinary shares.

The selling shareholders may, in addition to selling all or a portion of the ordinary shares beneficially owned by them as described above, sell or otherwise dispose of the ordinary shares in open market transactions, privately negotiated transactions, ordinary brokerage transactions, transactions in which the broker-dealer solicits purchasers, a combination of such methods or any other method permitted by applicable law, including pursuant to Rule 144 of the Securities Act. In addition, the selling shareholders shall be entitled to sell their ordinary shares without volume or time restrictions in connection with a third party's acquisition or proposed acquisition of us, or a tender offer for, merger or change of control of, us.

Underwriters or broker-dealers engaged by the selling shareholders may arrange for other underwriters or broker-dealers to participate in sales. If the ordinary shares are sold through underwriters or broker-dealers, the selling shareholders will be responsible for underwriting discounts or commissions or agent's commissions. The ordinary shares may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale; in the over-the-counter market; in transactions otherwise than on these exchanges or systems or in the over-the-counter market; through the writing of options, whether such options are listed on an options exchange or otherwise; ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; block trades in which a selling shareholder will engage a broker-dealer as agent, who will then attempt to sell the ordinary shares, but may position and resell a portion of the block as principal to facilitate the transaction; purchases by a broker-dealer as principal and resale by the broker-dealer for its account; an exchange distribution in accordance with the rules of the applicable exchange; ordinary brokerage transactions, transactions in which the broker-dealer solicits purchasers; privately negotiated transactions; or in short sale transactions. Broker-dealers may agree with the selling security holders to sell a specified number of such shares at a stipulated price per share; a combination of any such methods of sale; and any other method permitted pursuant to applicable law.

If the selling shareholders effect such transactions by selling ordinary shares to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling shareholders or commissions from purchasers of the ordinary shares for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the ordinary shares or otherwise, the selling shareholders may enter into hedging transactions with broker-dealers, which such broker-dealer may in turn engage in short sales of the ordinary shares in the course of hedging in positions they assume. The selling shareholders may also sell ordinary shares short and deliver ordinary shares covered by this prospectus to close out short

positions. The selling shareholders may also loan or pledge ordinary shares to broker-dealers that in turn may sell such shares.

In addition, the selling shareholders may pledge or grant an additional or substitute security interest in some or all of the ordinary shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the ordinary shares from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b) or other applicable provision of the Securities Act, amending, if necessary, the list of selling shareholders to include the pledgee, transferee or other successors in interest as selling shareholders under this prospectus. The selling shareholders also may transfer, gift and/or donate the ordinary shares in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus or any amendment to this prospectus under Rule 424(b) or other applicable provision of the Securities Act, amending, if necessary, the list of selling shareholders to include such transferee.

The selling shareholders and any underwriter(s) or broker-dealer participating in the distribution of the ordinary shares may be deemed to be "underwriters" within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the ordinary shares is made, a prospectus supplement, if required, will be distributed, which will set forth the aggregate amount of ordinary shares being offered and the terms of the offering, including the name or names of any underwriter(s), broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling shareholders and any discounts, commissions or concessions allowed or re-allowed or paid to such underwriter(s) or broker-dealers, where applicable, and any other facts material to the transaction.

Under the state securities laws, the ordinary shares may be sold only through registered or licensed brokers or dealers.

There can be no assurance that any selling shareholder will sell any or all of the ordinary shares registered pursuant to the registration statement, of which this prospectus forms a part.

The selling shareholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the ordinary shares by the selling shareholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the ordinary shares to engage in market-making activities with respect to the ordinary shares. All of the foregoing may affect the marketability of the ordinary shares and the ability of any person or entity to engage in market-making activities with respect to the ordinary shares.

Once sold under the registration statement, of which this prospectus forms a part, the ordinary shares will be freely tradable in the hands of persons other than our affiliates.

The Company will bear all expenses relating to the registration of the ordinary shares registered pursuant to the registration statement, of which this prospectus forms a part. We estimate these expenses to be approximately $38,000, which include the following categories of expenses:

The consolidated financial statements of Velti plc as of December 31, 2010 and 2011, and for each of the years in the three-year period ended December 31, 2011, and management's assessment of the effectiveness of internal control over financial reporting as of December 31, 2011 have been incorporated by reference herein in reliance upon the report of Baker Tilly Virchow Krause, LLP, independent registered public accounting firm, incorporated by reference herein, and upon the authority of said firm as experts in accounting and auditing.

The validity of the ordinary shares offered hereunder will be passed upon for us by Mourant Ozannes, our Jersey counsel.

Except as otherwise described in our Annual Report on Form 20-F for the fiscal year ended December 31, 2011, in our Reports on Form 6-K filed or submitted under the Exchange Act and incorporated by reference herein and as disclosed in this prospectus, no reportable material changes have occurred since December 31, 2011.

We are incorporating by reference in this prospectus the documents listed below and all amendments or supplements we may file to such documents, as well as any future filings we may make with the Commission on Form 20-F under the Exchange Act after the date of the initial registration statement and prior to the effectiveness of the registration statement, and after the date of this prospectus and prior to the time that all of the securities offered by this prospectus have been sold or de-registered.

In addition, we may incorporate by reference into this prospectus our reports on Form 6-K filed after the date of this prospectus (and before the time that all of the securities offered by this prospectus have been sold or de-registered) if we identify in the report that it is being incorporated by reference in this prospectus.

We are a Jersey company and are a "foreign private issuer" as defined in Rule 3b-4 under the Securities Exchange Act of 1934, or Exchange Act. As a result, our proxy solicitations are not subject to the disclosure and procedural requirements of Regulation 14A under the Exchange Act, transactions in our equity securities by our officers, directors and principal shareholders are exempt from Section 16 of the Exchange Act; and we are not required under the Exchange Act to file periodic reports and financial statements as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act.

U.S. laws do not necessarily extend either to us or our officers or directors. We are organized under the laws of the Bailiwick of Jersey. Most of our directors and officers reside outside of the U.S. Substantially all of the assets of both us and our directors and officers are located outside the U.S. As a result, it may not be possible for investors to effect service of process on either us or our officers and directors within the U.S., or to enforce against these persons or us, either inside or outside the U.S., a judgment obtained in a U.S. court predicated upon the civil liability provisions of the federal securities or other laws of the U.S. or any U.S. state.

We have appointed Velti USA, Inc., located at Steuart Tower, 1 Market Street, Suite 600, San Francisco, California 94105, as our agent to receive service of process with respect to any action brought against us in the U.S. under the federal securities laws of the U.S. or of the laws of any state of the U.S.

A judgment of a U.S. court is not directly enforceable in Jersey, but constitutes a cause of action which will be enforced by Jersey courts provided that:

Jersey courts award compensation for the loss or damage actually sustained by the plaintiff. Although punitive damages are generally unknown to the Jersey legal system, there is no prohibition on them either by statute or customary law. Whether a particular judgment may be deemed contrary to Jersey public policy depends on the facts of each case, though judgments found to be exorbitant, unconscionable, or excessive will generally be deemed as contrary to public policy. Moreover, certain defendants may qualify for protection under Protection of Trading Interests Act 1980, an act of the U.K. extended to Jersey by the Protection of Trading Interests Act 1980 (Jersey) Order, 1983. This Act

provides that a qualifying defendant is not liable for multiple damages, in excess of that required for actual compensation. A "qualifying defendant" for these purposes is a citizen of the U.K. and Colonies, a corporation or other limited liability entity organized under the laws of the U.K., Jersey or other territory for whose international relations the U.K. is responsible or a person conducting business in Jersey.

Jersey courts cannot enter into the merits of the foreign judgment and cannot act as a court of appeal or review over the foreign courts. We have been advised by our legal counsel in Jersey that it is doubtful that an original action based on U.S. federal or state securities laws could be brought before Jersey courts. In addition, a plaintiff who is not resident in Jersey may be required to provide a security bond in advance to cover the potential of the expected costs of any case initiated in Jersey. In addition, we have been further advised by our legal counsel in Jersey, that it is uncertain as to whether the courts of Jersey would entertain original actions or enforce judgments from U.S. courts against us or our officers and directors which originated from actions alleging civil liability under U.S. federal or state securities laws.
