DIGITAL RIVER, INC.
COMMON STOCK

        This prospectus relates to 1,480,000 shares of common stock of Digital River, Inc., par value $0.01 per share, that we may offer and issue from time to time in connection with our future acquisitions of other businesses, assets or securities.

        The amount and type of consideration we will offer and the other specific terms of each acquisition will be determined by negotiations with the owners or the persons who control the businesses, assets or securities to be acquired. We may structure business acquisitions in a variety of ways, including acquiring stock, other equity interests or assets of the acquired business or merging the acquired business with us or one of our subsidiaries. We expect that the price of the shares we issue will be related to their market price, either when we agree to the particular acquisition, when we issue the shares, or during some other negotiated period.

        We will pay all expenses of this offering. We do not expect to pay any underwriting discounts or commissions in connection with issuing these shares, although we may pay finder's fees in specific acquisitions. Any person receiving a finder's fee may be deemed an underwriter within the meaning of the Securities Act of 1933, as amended.

        We may also permit individuals or entities who have received or will receive shares of our common stock in connection with the acquisitions described above to use this prospectus to cover resales of those shares. If this happens, we will not receive any proceeds from such shares. See "Selling Stockholders" for the identity of any such individuals or entities.

        If an acquisition has a material financial effect on us, we will file subsequent to the acquisition a current report on Form 8-K and/or a post-effective amendment to the registration statement of which this prospectus is a part. The current report and/or post-effective amendment will contain financial and other information about the acquisition which is material to subsequent acquirors of the common stock offered by this prospectus, including, if applicable, pro forma information for us and historical financial information about the entity being acquired. We will also file a current report on Form 8-K and/or a post-effective amendment to the registration statement of which this prospectus is a part when an acquisition does not itself have a material effect upon us, but if aggregated with other acquisitions since the date of our most recent audited financial statements, the acquisition would have a material effect on us.

        On April    , 2005, the Securities and Exchange Commission declared effective our universal shelf registration statement on Form S-3 (File No. 333-122068) for the sale by us from time to time of our common stock, preferred stock, debt securities and/or warrants for a maximum aggregate offering price of $255,165,000.

Digital River, Inc.

Overview

        We are a provider of comprehensive e-commerce outsourcing solutions. We were incorporated in Delaware in 1994 and commenced offering products for sale through our clients' e-commerce stores in August 1996. As a leading global e-commerce outsource provider, we have developed a proprietary technology platform that allows us to provide our clients with a suite of e-commerce services, including e-commerce site development and hosting, site merchandising, order management, fraud prevention, denied parties screening, export controls, tax management, digital and physical product fulfillment, multi-lingual customer service, email marketing and advanced reporting and web analytics.

        Our solution allows our clients to promote and maintain their brands while leveraging our investment in infrastructure and technology. Our clients access our e-commerce platform over the Internet. From a shopper perspective, end-users enter the client site and are then seamlessly transferred to our e-commerce platform. End-users can then browse for products and make purchases online, and once purchases are made, we either deliver the products digitally to the end-user through the Internet or communicate the order through a third-party fulfillment agency for physical delivery.

        We also offer a wide range of analytics-based, strategic marketing services to help our clients increase their customer acquisition, retention and lifetime value. These services include paid search advertising, search engine optimization, affiliate marketing, site/store optimization and email optimization to help our clients increase their customer acquisition, retention and lifetime value.

        Our address is 9625 West 76th Street, Suite 150, Eden Prairie, Minnesota 55344, (952) 253-1234. We maintain a website at www.digitalriver.com. Information contained on, or accessed through, our website does not constitute a part of this prospectus.

RISK FACTORS

        You should carefully consider the risks described below before making an investment decision. The risks described below are not the only ones facing our company. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The value of our common stock could decline due to any of these risks, and you may lose all or part of your investment. This prospectus and the incorporated documents also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus.


Risks Related To Our Business

We have a history of losses.

        We were incorporated in February 1994 and conducted our first online sale through a client's Web store in August 1996. We have been in business for approximately 44 quarters, but have only sustained profitability for the last ten quarters through December 31, 2004, and have incurred significant losses since we were formed. As of December 31, 2004, we had an accumulated deficit of approximately $51.2 million. Our limited profitable operating history makes it difficult to evaluate our ability to sustain profitability in the future.

        The success of our business model depends upon our success in generating sufficient transaction and service fees from the use of our e-commerce solutions by existing and future clients. Accordingly, we must maintain our existing relationships and develop new relationships with software publishers, online retailers and physical goods clients. To achieve this goal, we intend to continue to expend significant financial and management resources on the development of additional services, sales and marketing, improved technology and expanded operations. If we are unable to maintain existing, and develop new, client relationships, we will not generate a profitable return on our investments and we will be unable to gain meaningful market share to justify those investments. Further, we may be unable to sustain profitability if our revenues decrease or increase at a slower rate than expected, or if operating expenses exceed our expectations and cannot be adjusted to compensate for lower than expected revenues.

Our operating results are subject to fluctuations in demand for products and services offered by us or our clients.

        Our quarterly and annual operating results are subject to fluctuations in demand for the products or services offered by us or our clients, such as anti-virus software, anti-spyware software, and tax preparation software. In particular, sales of anti-virus software represented a significant portion of our revenues in recent years, and continue to be very important to our business. In February 2005, Microsoft Corporation announced plans to acquire Sybari Software Inc., a producer of commercial anti-virus products. Microsoft simultaneously announced plans to introduce products to protect businesses and consumers from computer viruses and other security risks. To the extent that Microsoft or others successfully introduce products or services not sold through our platform that are competitive with products and services sold by current Digital River clients (including anti-virus products and services), our revenues could be materially adversely affected. If, as a result, our annual or quarterly revenues or operating profits fail to meet the guidance we provide to securities analysts and investors, or we otherwise fail to meet their expectations, the trading price of our common stock will likely decline.

2


Our operating results have fluctuated in the past and are likely to continue to do so, which could cause the price of our common stock to be volatile.

        Our quarterly and annual operating results have fluctuated significantly in the past and are likely to continue to do so in the future due to a variety of factors, some of which are outside our control. As a result, we believe that quarter-to-quarter and year-to-year comparisons of our revenue and operating results are not necessarily meaningful, and that these comparisons may not be accurate indicators of future performance. If our annual or quarterly operating results fail to meet the guidance we provide to securities analysts and investors or otherwise fail to meet their expectations, the trading price of our common stock will likely decline. Some of the factors that have or may contribute to fluctuations in our quarterly and annual operating results include:

        In addition, revenue generated by our software and digital commerce services is likely to fluctuate on a seasonal basis that is typical for the software publishing market in general. We believe that our first and fourth quarters are generally seasonally stronger than our second and third quarters due to the timing of demand of tax preparation software, the holiday selling period and the post-holiday retail season. We also believe that software publishers avoid new product releases in the summer months.

        Our operating expenses, which include: sales & marketing, product research & development and general & administrative expenses, are based on our expectations of future revenue. These expenses are relatively fixed in the short-term. If our revenue for a quarter falls below our expectations and we are unable to quickly reduce spending in response, our operating results for that quarter would be harmed. In addition, the operating results of companies in the e-commerce industry have, in the past, experienced significant quarter-to-quarter fluctuations that may adversely affect our stock price.

3


A loss of any client that accounts for a large portion of our revenue would cause our revenue to decline.

        Sales of products for one software publisher client, Symantec Corporation, accounted for approximately 27% of our revenue in 2004. In addition, Digital River independently sells proprietary Digital River services directly to customers as they purchase Symantec products. These services include product recovery services provided by Digital River for which separate fees are charged to end-users. In addition, Digital River derives revenues from e-commerce retailers and dealers who sell Symantec products or related Digital River services. In 2004, revenues derived from proprietary Digital River services sold to Symantec end-users and dealer network sales of Symantec products together amounted to approximately $16.6 million, or approximately 10.8% of total Digital River revenue. In addition, a limited number of other software and physical goods clients contribute a large portion of our annual revenue. Contracts with our clients are generally one or two years in length. If any one of these key contracts is not renewed or otherwise terminates, or if revenues from these clients decline for any other reason (such as competitive developments), our revenue would decline and our ability to sustain profitability would be impaired. It is important to our ongoing success that we maintain these key client relationships and, at the same time, develop new client relationships.

Our sales cycle is lengthy, which may cause us to incur substantial expenses and expend management time without generating corresponding revenue, which would impair our cash flow.

        We market our services directly to software publishers, online retailers and other prospective customers outside of the software industry. These relationships are typically complex and take time to finalize. Due to operating procedures in many organizations, a significant amount of time may pass between selection of our products and services by key decision-makers and the signing of a contract. The period between the initial sales call and the signing of a contract with significant sales potential is difficult to predict and typically ranges from six to twelve months. If at the end of a sales effort a prospective client does not purchase our products or services, we may have incurred substantial expenses and expended management time that cannot be recovered and that will not generate corresponding revenue. As a result, our cash flow and our ability to fund expenditures incurred during the sales cycle may be impaired.

General economic uncertainty may reduce our revenue and operating profits.

        The revenue growth and profitability of our business depends significantly on the overall demand for e-commerce solutions. We believe that the market for these solutions may be adversely affected by a number of factors, including reductions in capital expenditures by clients and potential weakening of the U.S. and foreign economies. The continued military responses to the 2001 terrorist attacks on the United States, the ongoing possibility of future terrorist attacks and the possibility of future armed conflicts may create adverse economic conditions and lead to weakening in the economy.

        These factors may, in turn, give rise to a number of market trends that may slow our revenue growth, including:

4

Our failure to attract and retain software and digital products publishers, manufacturers, online retailers and online channel partners as clients would cause our revenue and operating profits to decline.

        We generate revenue by providing outsourced services to software and digital products publishers, manufacturers, online retailers and online channel partners. If we cannot develop and maintain satisfactory relationships with software and digital products publishers, manufacturers, online retailers and online channel partners on acceptable commercial terms, we will likely experience a decline in revenue and operating profits. We also depend on our software and digital publisher clients creating and supporting software and digital products that end-users will purchase. If we are unable to obtain sufficient quantities of software and digital products for any reason, or if the quality of service provided by these software and digital products publishers falls below a satisfactory level, we could also experience a decline in revenue, operating profit and end-user satisfaction, and our reputation could be harmed. Our contracts with our software and digital products publisher clients are generally one to two years in duration, with an automatic renewal provision for additional one-year periods, unless we are provided with a written notice at least 90 days before the end of the contract. As is common in our industry, we have no long-term or exclusive contracts or arrangements with any software or digital products publishers that guarantee the availability of software or digital products. Software and digital products publishers that currently supply software or digital products to us may not continue to do so and we may be unable to establish new relationships with software or digital products publishers to supplement or replace existing relationships.

Implementing our acquisition strategy could result in dilution and operating difficulties leading to a decline in revenue and operating profit.

        We have acquired, and intend to continue engaging in strategic acquisitions of, businesses, technologies, services and products, such as businesses that provide outsourcing services to software publishers. For example, in April 2004, we acquired element 5, a provider of outsourced e-commerce solutions. The process of integrating an acquired business, technology, service or product into our business and operations may result in unforeseen operating difficulties and expenditures. Integration of an acquired business also may disrupt our ongoing business, distract management and make it difficult to maintain standards, controls and procedures. Moreover, the anticipated benefits of any acquisition may not be realized. If a significant number of clients of the acquired businesses cease doing business with us, we would experience lost revenue and operating profit, and any synergies from the acquisition may be lost. Future acquisitions could result in potentially dilutive issuances of equity securities, the incurrence of debt, contingent liabilities, amortization of intangible assets or impairment of goodwill.

Electronic software delivery, or ESD, is still an evolving and unproven technology and the industry may ultimately fail to accept ESD.

        Our success will depend in large part on the continued growth in end-user acceptance of ESD as a method of distributing software products. ESD is a relatively new method of distributing software products to end-users, and unless ESD gains widespread market acceptance, we will be unable to achieve our business plan. Factors that are likely to influence the market acceptance of ESD include:

5

        Even if ESD achieves widespread acceptance, we may be unable to overcome the substantial existing and future technical challenges associated with electronically delivering software reliably and consistently on a long-term basis. Our failure to do so would also impair our ability to execute our business plan.

Developments in accounting standards may cause us to increase our recorded expenses, which in turn would jeopardize our ability to demonstrate sustained profitability.

        In January 2002, we adopted Statement of Financial Accounting Standard No. 142, "Goodwill and Other Intangible Assets" (SFAS No. 142). The statement generally establishes that goodwill and intangible assets with indefinite lives are not amortized but are to be tested on an annual basis for impairment and, if impaired, are recorded as an impairment charge in income from operations. As of December 31, 2004, we had unamortized goodwill with an indefinite life of $148.1 million from our acquisitions made in 2004 and previous years. Our acquisition of element 5 for example has resulted in a significant increase in unamortized goodwill. If a portion of our unamortized goodwill is determined for any reason to be impaired, the subsequent accounting of the impaired portion as an expense would lower our earnings and jeopardize our ability to demonstrate sustained profitability, which could cause our stock price to decline.

        The Financial Accounting Standards Board also recently adopted a standard to require that the fair value of stock options and other share based payments be reflected as an expense item in the financial statements of public companies for years beginning after June 15, 2005. As a result of the adoption of this standard, our recorded non-cash expenses will significantly increase, which may impair our ability to maintain profitability.

Increasing consumer acceptance of the Internet as a medium of commerce is important to the success of our business strategy and our future revenue growth.

        The failure of the Internet to continue developing into a significant commercial medium would harm our ability to increase our revenue and execute our business strategy. Rapid growth in the acceptance and use of the Internet as an effective medium of commerce is a recent development. The acceptance and use of the Internet may not continue to develop and a sufficiently broad base of consumers may not adopt and continue to use the Internet as a medium of commerce. We rely on purchasers who have historically used traditional means of commerce to purchase goods or transact business. If we are to be successful, these purchasers must accept and use the Internet as a means of purchasing goods and services and exchanging information. We cannot predict the rate at which these purchasers will do so.

The growth of the market for our services depends on the development and maintenance of the Internet infrastructure.

        Our business is based on delivering services over the Internet, and the success of our business therefore depends on the development and maintenance of a sound Internet infrastructure. This includes maintenance of a reliable network backbone with the necessary speed, data capacity and security, as well as timely development of complementary products such as high-speed modems, for providing reliable Internet access and services. Our ability to increase the speed and scope of our services is limited by, and depends upon, the speed and reliability of both the Internet and our clients' internal networks. Consequently, as Internet usage increases, the growth of the market for our services depends upon improvements made to the Internet as well as to individual client's networking

6


infrastructures to alleviate overloading and congestion. In addition, any delays in the adoption of new standards and protocols required to govern increased levels of Internet activity or increased governmental regulation may have a detrimental effect on the Internet infrastructure.

Because the e-commerce industry is highly competitive and has low barriers to entry, we may be unable to compete effectively.

        The market for e-commerce solutions is extremely competitive and we may find ourselves unable to compete effectively. Because there are relatively low barriers to entry in the e-commerce market, we expect competition to intensify as current competitors expand their product offerings and new competitors enter the market. In addition, our clients may become competitors in the future Increased competition is likely to result in price reductions, lower average sales prices, reduced margins, longer sales cycles and a decrease or loss of our market share, any of which could negatively impact our revenue and earnings. We face competition from the following sources:

        We believe that the principal competitive factors in our market are breadth of products and services, number of clients and online channel partnerships, brand recognition, system reliability and scalability, price, customer service, speed and accessibility and ease of use, speed to market, convenience and quality of delivery. The online channel partners and the other companies described above may compete directly with us by adopting a similar business model. Moreover, while some of these companies are also clients or potential clients of ours, they may compete with our e-commerce outsourcing solution to the extent that they develop e-commerce systems or acquire such systems from other software vendors or service providers.

        Many of our competitors have, and new potential competitors may have, more experience developing Internet-based software and e-commerce solutions, larger technical staffs, larger customer bases, more established distribution channels and customer relationships, greater brand recognition and greater financial, marketing and other resources than us. In addition, competitors may be able to develop services that are superior to our services, achieve greater customer acceptance or have significantly improved functionality as compared to our existing and future products and services. Our competitors may be able to respond more quickly to technological developments and changes in customers' needs. Our inability to compete successfully against current and future competitors could cause our revenue and earnings to decline.

7


Failure to properly manage and sustain our expansion efforts could strain our management and other resources.

        Our ability to successfully offer services and implement our business plan in a rapidly evolving market requires an effective planning and management process. We have rapidly and significantly expanded the depth and breadth of our service offerings. Failure to properly manage this expansion could place a significant strain on our managerial, operational and financial resources. To manage this expansion, we are required to continually:

        We may be unable to install management information and control systems in an efficient and timely manner, and our current or planned personnel, systems, procedures and controls may be inadequate to support our operations.

Failure to develop our technology to accommodate increased traffic could reduce demand for our services and impair the growth of our business.

        We periodically enhance and expand our technology and transaction-processing systems, network infrastructure and other technologies to accommodate increases in the volume of traffic on our technology platform. Any inability to add software and hardware or to develop and upgrade existing technology, transaction-processing systems or network infrastructure to manage increased traffic on this platform may cause unanticipated systems disruptions, slower response times and degradation in client services, including impaired quality and speed of order fulfillment. Failure to manage increased traffic could harm our reputation and significantly reduce demand for our services, which would impair the growth of our business. We may be unable to improve and increase the capacity of our network infrastructure sufficiently or anticipate and react to expected increases in the use of the platform to handle increased volume. Further, additional network capacity may not be available from third-party suppliers when we need it. Our network and our suppliers' networks may be unable to maintain an acceptable data transmission capability, especially if demands on the platform increase.

        We continue to enhance our e-commerce platforms to better support new features and functionality demanded by our client base. Failure of these to perform as expected could lead to client dissatisfaction and loss of business.

Our industry is characterized by rapid technological change that may make our technology and systems obsolete or cause us to incur substantial costs to adapt to these changes.

        To remain competitive, we must continue to enhance and improve the responsiveness, functionality and features of our CST technology platform and the underlying network infrastructure. If we incur significant costs without adequate results, or are unable to adapt rapidly to technological changes, we may fail to achieve our business plan. The Internet and the e-commerce industry are characterized by rapid technological change, changes in user and client requirements and preferences, frequent new product and service introductions embodying new technologies and the emergence of new industry standards and practices that could render our technology and systems obsolete. To be successful, we must adapt to rapid technological change by licensing and internally developing leading technologies to enhance our existing services, developing new products, services and technologies that address the increasingly sophisticated and varied needs of our clients, and responding to technological advances and emerging industry standards and practices on a cost-effective and timely basis. The development of our CST platform and other proprietary technologies involves significant technical and business risks. We

8


may fail to use new technologies effectively or fail to adapt our proprietary technology and systems to client requirements or emerging industry standards.

System failures could reduce the attractiveness of our service offerings.

        We provide commerce, marketing and delivery services to our clients and end-users through our proprietary technology transaction processing and client management systems. These systems also maintain an electronic inventory of products and gather consumer marketing information. The satisfactory performance, reliability and availability of the technology and the underlying network infrastructure are critical to our operations, level of client service, reputation and ability to attract and retain clients. We have experienced periodic interruptions, affecting all or a portion of our systems, which we believe will continue to occur from time to time. Any systems damage or interruption that impairs our ability to accept and fill client orders could result in an immediate loss of revenue to us, and could cause some clients to purchase services offered by our competitors. In addition, frequent systems failures could harm our reputation.

        Our systems and operations are vulnerable to damage or interruption from:

        We do not carry sufficient business interruption insurance to fully compensate us for losses that may occur.

We may become liable to clients who are dissatisfied with our services.

        We design, develop, implement and manage e-commerce solutions that are crucial to the operation of our clients' businesses. Defects in the solutions we develop could result in delayed or lost revenue, adverse end-user reaction, and/or negative publicity which could require expensive corrections. As a result, clients who experience these adverse consequences either directly or indirectly as a result of our services could bring claims against us for substantial damages. Any claims asserted could exceed the level of any insurance coverage that may be available to us. Moreover, the insurance we carry may not continue to be available on economically reasonable terms, or at all. The successful assertion of one or more large claims that are uninsured, that exceed insurance coverage or that result in changes to insurance policies (including premium increases) could adversely affect our operating results or financial condition.

Our chief executive officer and key technical employees are critical to our business, and if they do not remain with us in the future, we may be unable to effectively replace them.

        Our future success significantly depends on the continued services and performance of our senior management, particularly Joel A. Ronning, our chief executive officer. Our performance also depends on our ability to retain and motivate our key technical employees who are skilled in maintaining our proprietary technology platform. The loss of the services of any of our executive officers or key technical employees could harm our business if we are unable to effectively replace that officer or employee, or if that person should decide to join a competitor or otherwise directly or indirectly compete with us. Further, we may need to incur additional operating expenses and divert other management time in order to search for a replacement.

9


We must continually attract and retain technical and other key personnel in order to successfully execute our business strategy.

        Our future success depends on our ability to continue to identify, attract, hire, train, retain and motivate highly skilled technical, managerial, operations, merchandising, sales and marketing and client service personnel. Competition for these personnel is intense, particularly in the Internet industry. We may be unable to successfully attract, assimilate or retain sufficiently qualified personnel. Failure to do so could harm our business growth and profitability. In addition, the market price of our common stock has fluctuated substantially since our initial public offering in August 1998. Consequently, potential employees may perceive our equity incentives as less attractive and current employees whose equity incentives are no longer attractively priced may choose not to remain with our organization. In that case, our ability to attract employees will be adversely affected. Additionally, the Financial Accounting Standards Board recently adopted a proposal requiring that the fair value of stock options and other share based payments be reflected as an expense item in the financial statements of public companies for quarters beginning after June 15, 2005. As a result, our ability to use stock options as equity incentives will be adversely affected, which will make it more difficult to compete for and attract qualified personnel. Finally, should our stock price substantially decline, the retention value of stock options granted since our initial public offering will decline and employees who hold such options may choose not to remain with our organization.

Protecting our intellectual property is critical to our success.

        We regard the protection of our trademarks, copyrights, trade secrets and other intellectual property as critical to our success. We rely on a combination of patent, copyright, trademark, service mark and trade secret laws and contractual restrictions to protect our proprietary rights. We have entered into confidentiality and invention assignment agreements with our employees and contractors, and nondisclosure agreements with parties with whom we conduct business, in order to limit access to and disclosure of our proprietary information. These contractual arrangements and the other steps taken by us to protect our intellectual property may not prevent misappropriation of our technology or deter independent third-party development of similar technologies. We also seek to protect our proprietary position by filing U.S. and foreign patent applications related to our proprietary technology, inventions and improvements that are important to the development of our business. Proprietary rights relating to our technologies will be protected from unauthorized use by third parties only to the extent they are covered by valid and enforceable patents or are effectively maintained as trade secrets. We pursue the registration of our trademarks and service marks in the U.S. and internationally. Effective trademark, service mark, copyright and trade secret protection may not be available in every country in which our services are made available online.

        The steps we have taken to protect our proprietary rights may be inadequate and third parties may infringe or misappropriate our trade secrets, trademarks and similar proprietary rights. Any significant failure on our part to protect our intellectual property could make it easier for our competitors to offer similar services and thereby adversely affect our market opportunities. In addition, litigation may be necessary in the future to enforce our intellectual property rights, to protect our trade secrets or to determine the validity and scope of the proprietary rights of others. Litigation could result in substantial costs and diversion of management and technical resources.

Claims of infringement of other parties' intellectual property rights could require us to expend significant resources, enter into unfavorable licenses or require us to change our business plans.

        From time to time we are named as a defendant in lawsuits claiming that we have, in some way, violated the intellectual property rights of others. Existing lawsuits in this area, as well as any future assertions or prosecutions of claims like these, could require us to expend significant financial and managerial resources. The defense of any claims, with or without merit, could be time-consuming,

10


result in costly litigation and diversion of technical and management personnel, cause product enhancement delays or require that we develop non-infringing technology or enter into royalty or licensing agreements. Royalty or licensing agreements, if required, may be unavailable on terms acceptable to us or at all. In the event of a successful claim of infringement against us and our failure or inability to develop non-infringing technology or license the infringed or similar technology on a timely basis, we may be unable to pursue our current business plan.

Claims against us related to the software products that we deliver electronically and the tangible goods that we deliver physically could also require us to expend significant resources.

        Claims may be made against us for negligence, copyright or trademark infringement, products liability or other theories based on the nature and content of software products or tangible goods that we deliver electronically and physically. Because we did not create these products, we are generally not in a position to know the quality or nature of the content of these products. Although we carry general liability insurance and require that our customers indemnify us against end-user claims, our insurance and indemnification measures may not cover potential claims of this type, may not adequately cover all costs incurred in defense of potential claims, or may not reimburse us for all liability that may be imposed. Any costs or imposition of liability that are not covered by insurance or indemnification measures could be expensive and time-consuming to address, distract management and delay product deliveries, even if we are ultimately successful in the defense of these claims.

Security breaches could hinder our ability to securely transmit confidential information.

        A significant barrier to e-commerce and communications is the secure transmission of confidential information over public networks. Any compromise or elimination of our security could be costly to remedy, damage our reputation and expose us to liability, and dissuade existing and new clients from using our services. We rely on encryption and authentication technology licensed from third parties to provide the security and authentication necessary for secure transmission of confidential information, such as end-user credit card numbers. A party who circumvents our security measures could misappropriate proprietary information or interrupt our operations.

        We may be required to expend significant capital and other resources to protect against security breaches or address problems caused by breaches. Concerns over the security of the Internet and other online transactions and the privacy of users could deter people from using the Internet to conduct transactions that involve transmitting confidential information, thereby inhibiting the growth of our business. To the extent that our activities or those of third-party contractors involve the storage and transmission of proprietary information, such as credit card numbers, security breaches could damage our reputation and expose us to a risk of loss or litigation and possible liability. Our security measures may not prevent security breaches and failure to prevent security breaches could lead to a loss of existing clients and deter potential clients away from our services.

Loss of our credit card acceptance privileges would seriously hamper our ability to process the sale of digital goods.

        The payment by end-users for the purchase of digital goods that we process is typically made by credit card. If we incur significant instances of credit card fraud over an extended period of time, it may result in penalties and termination of our credit card acceptance privileges. Loss of our credit card acceptance privileges would severely impact our ability to process the sale of digital goods where the payment method is by credit card. We may be required to expend significant capital and other resources to protect against these fraudulent transactions.

11


The listing of our network addresses on anti-SPAM lists could harm our ability to service our clients and deliver goods over the Internet.

        Certain privacy and anti-email proponents have engaged in a practice of gathering, and publicly listing, network addresses that they believe have been involved in sending unwanted, unsolicited emails commonly known as SPAM. In response to user complaints about SPAM, Internet service providers have from time to time blocked such network addresses from sending emails to their users. If our network addresses mistakenly end up on these SPAM lists, our ability to provide services for our clients and consummate the sales of digital and physical goods over the Internet could be harmed.

Changes in government regulation could limit our Internet activities or result in additional costs of doing business over the Internet.

        We are subject to the same federal, state and local laws as other companies conducting business over the Internet. Today, there are relatively few laws specifically directed towards conducting business over the Internet. The adoption or modification of laws related to the Internet could harm our business, operating results and financial condition by increasing our costs and administrative burdens. Due to the increasing popularity and use of the Internet, many laws and regulations relating to the Internet are being debated at the international, federal and state levels. These laws and regulations could cover issues such as:

        Applicability to the Internet of existing laws governing issues such as property ownership, copyrights and other intellectual property issues, taxation, libel, obscenity and personal privacy could also harm our operating results and substantially increase the cost to us of doing business. For example, numerous state legislatures have proposed that tax rules for Internet retailing and catalog sales correspond to enacted tax rules for sales from physical stores. Any requirement that we collect sales tax for each online purchase and remit the tax to the appropriate state authority would be a significant administrative burden to us and possibly depress online sales. This and any other change in laws applicable to the Internet might also require significant management resources to respond appropriately. The vast majority of these laws were adopted prior to the advent of the Internet, and do not contemplate or address the unique issues raised thereby. Those laws that do reference the Internet, such as the Digital Millennium Copyright Act, are only beginning to be interpreted by the courts and their applicability and reach are therefore uncertain.

Laws relating to user information and online privacy may limit the collection and use of end-user data for our clients.

        We collect and maintain end-user data for our clients, which subjects us to increasing international, federal and state regulation related to online privacy and the use of personal user information.

12


Congress recently enacted anti-SPAM legislation with which we must comply when providing email campaigns for our clients. Bills are pending in Congress and in various states that address online privacy protections. Several states have proposed, and some have enacted, legislation that would limit the use of personal user information or require online services to establish privacy policies. In addition, the U.S. Federal Trade Commission, or FTC, has urged Congress to adopt legislation regarding the collection and use of personal identifying information obtained from individuals when accessing Web sites. In the past, the emphasis has been on information obtained from minors. Focus has now shifted to include online privacy protection for adults. If such legislation is adopted, it may include requirements that companies establish procedures to, among other things:

        Even in the absence of laws requiring companies to establish these procedures, the FTC has settled several proceedings resulting in consent decrees in which Internet companies have been required to establish programs regarding the manner in which personal information is collected from users and provided to third parties. We could become a party to a similar enforcement proceeding. These regulatory and enforcement efforts could limit our collection of demographic and personal information from end-users, which could adversely affect our ability to comprehensively serve our clients.

The adoption and implementation of international laws and regulations applicable to e-commerce may impair our efforts to expand revenue from international transactions.

        The European Union has adopted a privacy directive that regulates the collection and use of information that identifies an individual person. These regulations may inhibit or prohibit the collection and sharing of personal information in ways that could harm our clients or us. The globalization of Internet commerce may be harmed by these and similar regulations because the European Union privacy directive prohibits transmission of personal information outside the European Union. The United States and the European Union have negotiated an agreement providing a "safe harbor" for those companies who agree to comply with the principles set forth by the U.S. Department of Commerce and agreed to by the European Union. Failure to comply with these principles may result in fines, private lawsuits and enforcement actions. These enforcement actions can include interruption or shutdown of operations relating to the collection and sharing of information pertaining to citizens of the European Union. Certain countries in the Asia-Pacific region have also adopted, or are considering adopting, privacy laws similar to those of the European Union, which may impair our ability to expand our revenue from those countries.

        In addition, in July 2003, the European Union implemented rules regarding the collection and payment of Value Added Tax, or VAT. These rules require VAT to be charged on supply delivered over electronic networks, including software and computer services, as well as information and cultural, artistic, sporting, scientific, educational, entertainment and similar services. These services are now being taxed in the country where the purchaser resides rather than where the supplier is located. Historically, suppliers of digital products that existed outside the European Union were not required to collect or remit VAT on digital orders made to purchasers in the European Union. With the

13


implementation of these rules, we are required to collect and remit VAT on digital orders received from purchasers in the European Union which effectively raises the price for these goods by the VAT amount. This price increase could serve to discourage purchasing of our products and services which in turn could adversely affect our operating results and financial condition.

Compliance with future laws imposed on e-commerce may substantially increase our costs of doing business or otherwise adversely affect our ability to offer our services.

        Because our services are accessible worldwide, and we facilitate sales of products to end-users worldwide, foreign jurisdictions may claim that we are required to comply with their laws. Laws regulating Internet companies outside of the United States may be less favorable than those in the United States, giving greater rights to consumers, content owners and users. Compliance may be more costly or may require us to change our business practices or restrict our service offerings relative to those provided in the United States. Any failure to comply with foreign laws could subject us to penalties ranging from fines to bans on our ability to offer our services.

        As our services are available over the Internet in multiple states and foreign countries, these jurisdictions may claim that we are required to qualify to do business as a foreign corporation in each state or foreign country. We and/or our subsidiaries are qualified to do business only in California, Colorado, Connecticut, Delaware, Georgia, Iowa, Michigan, Minnesota, New Jersey, New York, North Carolina, Ohio, Utah and Washington. Failure to qualify as a foreign corporation in a required jurisdiction could subject us to taxes and penalties and could result in our inability to enforce contracts in these jurisdictions.

        In addition, we are subject to United States laws governing the conduct of business with other countries, such as export control laws, which prohibit or restrict the export of goods, services and technology to designated countries, denied persons or denied entities from the United States. Violation of these laws could result in fines or other actions by regulatory agencies and result in increased cost of doing business and reduced profits. In addition, any significant changes in these laws, particularly an expansion in the export control laws, will increase our costs of compliance and may further restrict our overseas client base.

We intend to continue to expand our international operations and these efforts may not be successful in generating additional revenue.

        We sell products and services to end-users outside the United States and we intend to continue to expand our international presence. Expansion into international markets, particularly the European and Asia-Pacific regions, requires significant resources that we may fail to recover by generating additional revenue. Conducting business outside of the United States is subject to risks, including:

14

        These risks have grown with the recent acquisition of element 5, which has substantial operations outside the U.S. and our expansion into the Asia-Pacific region.

        We may be unable to successfully and cost-effectively market, sell and distribute our services in foreign markets. This may be more difficult or take longer than anticipated especially due to international challenges, such as language barriers, currency exchange issues and the fact that the Internet infrastructure in foreign countries may be less advanced than the U.S. Internet infrastructure. If we are unable to successfully expand our international operations, or manage this expansion, our operating results and financial condition could be harmed.

New obligations to collect or pay sales tax could substantially increase the cost to us of doing business.

        Currently, we collect sales, use or other similar taxes with respect to electronic software download in states where we believe that we have nexus. The application of sales related taxes to interstate and international sales over the Internet is unclear and evolving. We are already required to collect and remit VAT in the European Union, for example. Local, state or foreign jurisdictions may seek to impose sales or use tax collection obligations on out-of-state companies like ours that engage in e-commerce. A successful assertion by one or more states or any foreign country that we should collect sales, use or other taxes on the sale of merchandise through our physical goods clients or on physical shipments of software could harm our results of operations. In addition, any failure by a physical goods client to collect obligatory sales or use taxes could cause the relevant jurisdiction to attempt imposing that obligation on us.

Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses.

        Keeping abreast of, and in compliance with, changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and Nasdaq Stock Market rules, have required an increased amount of management attention and external resources. We intend to invest all reasonably necessary resources to comply with evolving corporate governance and public disclosure standards, and this investment may result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

We may need to raise additional capital to achieve our business objectives, which could result in dilution to existing investors or increase our debt obligations.

        We require substantial working capital to fund our business. If capital requirements vary materially from those currently planned, we may require additional financing sooner than anticipated. We filed with the Securities and Exchange Commission a universal shelf registration statement on Form S-3 pursuant to which we may sell up to $255 million in equity or debt securities. In addition, we filed with the Securities and Exchange Commission an acquisition shelf registration statement on Form S-4, of which this prospectus is a part, pursuant to which we may issue up to 1,480,000 shares of common stock in connection with future acquisitions of other businesses, assets or securities. If additional funds are raised through the issuance of equity securities, the percentage ownership of our stockholders will be reduced, stockholders may experience additional dilution or these equity securities may have rights, preferences or privileges senior to those of our common stock. In June 2004, we issued 1.25% convertible notes which require us to make interest payments and will require us to pay principal when the notes become due in 2024 or in the event of acceleration under certain circumstances, unless the notes are converted into our common stock prior to that. We may not have sufficient capital to service this or any future debt securities that we may issue, and the conversion of the notes into our common stock may result in further dilution to our stockholders. Our capital requirements depend on several factors, including the rate of market acceptance of our products, the ability to expand our client base

15


and the growth of sales and marketing. We have had significant operating losses and negative cash flow from operations since inception. Additional financing may not be available when needed, on terms favorable to us or at all. If adequate funds are not available or are not available on acceptable terms, we may be unable to develop or enhance our services, take advantage of future opportunities or respond to competitive pressures, which would harm our operating results and adversely affect our ability to sustain profitability.

Internet-related stock prices are especially volatile and this volatility may depress our stock price or cause it to fluctuate significantly.

        The stock market, and the trading prices of Internet-related companies in particular, have been notably volatile. This volatility is likely to continue in the short-term and is not necessarily related to the operating performance of affected companies. This broad market and industry volatility could significantly reduce the price of our common stock at any time, without regard to our operating performance. Factors that could cause our stock price in particular to fluctuate include, but are not limited to:

        In addition, our stock price may be impacted by the short sales and actions of other parties who may disseminate misleading information about us in an effort to profit from fluctuations in our stock price.

Our involvement in class-action litigation relating to our IPO may adversely affect our results of operations and distract management.

        We are party to a lawsuit which alleges that we, certain of our officers and directors and the underwriters of our initial public offering, or IPO, violated Section 11 of the Securities Act of 1933 based on allegations that our IPO registration statement and prospectus failed to disclose material facts regarding the compensation to be received by, and the stock allocation practices of, the IPO

16


underwriters. Similar complaints, pursuing similar theories, were filed in the same court against hundreds of other public companies.

        The IPO lawsuit, as well as any future allegations that we may have, in some way, violated securities laws could require us to expend significant financial and managerial resources and could result in further volatility of our stock price. The defense of any claims, with or without merit, could be time-consuming, result in costly litigation and divert technical and management personnel.

We may need to recognize and record income tax expense in the future while having no cash outlay for these taxes.

        Because we have a substantial net operating loss carryforward, the related deferred tax asset is fully reserved on our balance sheet. At some future date when we meet the requirements, we may reflect the benefit of the deferred tax asset and taxation of our financial results in our financial statements. The recognition of taxes may adversely affect the trading price of our stock in the stock market. It is also possible under existing accounting rules that we may be required to record income tax expense although we may have no cash outlay for these taxes or the ability to recognize the deferred tax asset under current accounting rules. In addition, we may also be expected to pay alternative minimum tax or foreign taxes even though we have a net operation loss carryforward.

Provisions of our charter documents, other agreements and Delaware law may inhibit potential acquisition bids for us.

        Certain provisions of our amended and restated certificate of incorporation, bylaws, other agreements and Delaware law could make it more difficult for a third party to acquire us, even if a change in control would be beneficial to our stockholders.


Risks Related to the Acquisition of Element 5 AG

element 5 has a history of losses and has yet to achieve sustained profitability.

        element 5 has experienced significant losses since inception ($10.2 million through March 31, 2004) and has experienced significant negative cash flows from operations. To address these risks, we and element 5 must, among others things, maintain existing and develop new relationships with independent software publishers, online retailers and other companies outside of the software market, maintain and increase element 5's client base, implement and successfully execute its business and marketing strategy, continue to develop and upgrade its technology and transaction-processing systems, provide superior customer service and order fulfillment, respond to competitive developments, and attract, retain and motivate qualified personnel. There can be no assurances that we will be successful in addressing such risks, and the failure to do so could have a material adverse effect on our business, financial condition and results of operations.

If we do not successfully integrate element 5, our business will be adversely affected.

        Our acquisition of element 5 in April 2004 is recent. We therefore have a very limited operating history with element 5 and limited experience in managing its business. Integrating element 5 is a complex and time-consuming process. Prior to the acquisition, Digital River and element 5 operated independently, each with its own business, corporate culture, locations, employees and systems. Eventually, we intend to operate as a combined organization utilizing common technology, information and communication systems, operating procedures, financial controls, and human resource practices. There may be substantial difficulties, costs and delays involved in any integration of element 5 into Digital River. These may include:

17


        Many of these risks are accentuated because element 5's operations, employees and customers are largely located outside of the U.S. Any one or all of these factors may increase operating costs or lower anticipated financial performance. Many of these factors are also outside of our control. Achieving anticipated synergies and the potential benefits underlying our reasons for the acquisition will depend on successful integration of the two businesses. The failure to integrate element 5 successfully would have a material adverse effect on our business, financial condition and results of operations.

We may be unable to retain element 5's customers.

        There can be no assurance that we will be able to retain element 5's customers following the acquisition. A failure to retain element 5's customers could have a material adverse effect on our financial condition and profitability.

As a result of the acquisition of element 5, we will be exposed to greater risk from currency fluctuations.

        Approximately one half of element 5's revenue and most of its costs are denominated in Euros and currencies other than U.S. dollars. As a result, a greater proportion of our revenues, earnings and costs will now be subject to currency fluctuations. We do not have, and we do not have plans to implement, a currency hedging program to mitigate the effect of fluctuations of currency prices on our financial results. As a result, our future operating results may be subject to fluctuations due to volatility in foreign currency exchange markets.

DISTRIBUTION OF SECURITIES

        The 1,480,000 shares of Digital River common stock covered by this prospectus are available for use in connection with acquisitions by us of other businesses, assets or securities in business combination transactions. The consideration offered by us in such acquisitions, in addition to any shares of common stock offered by this prospectus, may include cash, assets, debt or other securities, that may be convertible into shares of common stock of Digital River covered by this prospectus, or assumption by us of liabilities of the businesses, assets or securities being acquired, or a combination. The amount and type of consideration we will offer and the other specific terms of each acquisition will be determined by negotiations with the owners or the persons who control the businesses, assets or securities to be acquired after taking into account the current and anticipated future value of such businesses, assets or securities, along with all other relevant factors. We may structure business acquisitions in a variety of ways, including acquiring stock, other equity interests or assets of the acquired business or merging the acquired business with us or one of our subsidiaries. The shares of common stock issued to the owners of the businesses, assets or securities to be acquired normally are valued at a price reasonably related to the market value of such common stock either at the time an agreement is reached regarding the terms of the acquisition, at the time we issue the shares, or during some other negotiated period.

        This prospectus may be supplemented to furnish the information necessary for a particular negotiated transaction and the registration statement of which this prospectus is a part will be amended or supplemented, where appropriate, to supply information concerning an acquisition.

        All expenses of this registration will be paid by us. It is not expected that underwriting discounts or commissions will be paid by us in connection with issuances of shares of common stock under this prospectus. However, finders' fees or brokers' commissions may be paid from time to time in connection with specific acquisitions, and the fees may be paid through the issuance of shares of common stock covered by this prospectus. Any person receiving a fee may be deemed to be an underwriter within the meaning of the Securities Act.

        We may permit individuals or entities who have received or will receive shares of our common stock in connection with the acquisitions described above, or their transferees or successors-in-interest, to use this prospectus to cover the resale of such shares. See "Selling Stockholders," as it may be amended or supplemented from time to time, for a list of those individuals or entities that are authorized to use this prospectus to sell their shares of Digital River common stock.

19



 SELLING SECURITYHOLDERS

        The selling stockholders listed in any supplement to this prospectus, and any transferee or successors-in-interest to those persons, may from time to time offer and sell, pursuant to this prospectus, some or all of the shares covered by this prospectus.

        Resales by selling stockholders may be made directly to investors or through a securities firm acting as an underwriter, broker or dealer. When resales are to be made through a securities firm, such securities firm may be engaged to act as the selling stockholder's agent in the sale of the shares by such selling stockholder, or the securities firm may purchase shares from the selling stockholders as principal and thereafter resell such shares from time to time. The fees earned by or paid to such securities firm may be the normal stock exchange commission or negotiated commissions or underwriting discounts to the extent permissible. In addition, such securities firm may effect resales through other securities dealers, and customary commissions or concessions to such other dealers may be allowed. Sales of shares may be at negotiated prices, at fixed prices, at market prices or at prices related to market prices then prevailing. Any such sales may be made on The Nasdaq National Market, in the over-the-counter market, by block trade, in special or other offerings, directly to investors or through a securities firm acting as agent or principal, or through a combination of such methods. Any participating securities firm may be indemnified against certain liabilities including liabilities under the Securities Act. Any participating securities firm may be deemed to be an underwriter within the meaning of the Securities Act, and any commission earned by such firm may be deemed to be underwriting discounts or commissions under the Securities Act.

        In connection with resales of the shares sold under this prospectus, if required, a prospectus supplement or a post-effective amendment to the registration statement of which this prospectus is a party will be filed under Rule 424 (b) under the Securities Act, disclosing the name of any selling stockholder, the participating securities firm, if any, the number of shares involved, any material relationship a selling stockholder may have with us or our affiliates within the past three years, and other details of such resale to the extent appropriate. Information concerning the selling stockholders will be obtained from the selling stockholders.

        Stockholders may also offer shares of stock issued in past and future acquisitions by means of prospectuses under other available registration statements or pursuant to exemptions from the registration requirements of the Securities Act, including sales which meet the requirements of Rule 145(d) under the Securities Act, and stockholders should seek the advice of their own counsel with respect to the legal requirements for such sales.

        (e)   Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

        (f)    The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request.

        (g)   The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective.
