Previous wording

Our target customers are companies that develop and market high volume business and consumer products in semiconductors, computing, data centers, networks, artificial intelligence (“AI”), tablets, handheld devices, mobile applications, gaming and graphics, high-definition televisions, cryptography and data security. The electronics industry is intensely competitive and has been impacted by rapid technological change, short product life cycles, cyclical market patterns, price erosion and increasing foreign and domestic competition. We are subject to many risks beyond our control that influence whether or not we are successful in winning target customers or retaining existing customers, including, primarily, competition in a particular industry, market acceptance of such customers’ products and the financial resources of such customers. In particular, DRAM manufacturers, which make up a significant part of our revenue, are prone to significant business cycles and have suffered material losses and other adverse effects to their businesses, leading to industry consolidation from time to time that may result in loss of revenue under our existing license agreements or loss of target customers. Additionally, AI has been developing at a rapid pace and continues to evolve and change, especially with robust growth for AI infrastructure. We cannot predict whether the demand for AI solutions and therefore the demand for our products that support the AI ecosystem and infrastructure will continue and at what pace. The adoption of AI solutions by our customers and/or their end users may not develop in the manner or in the time periods we anticipate and, as the markets for AI solutions are still developing, demand for our products that support AI may be unpredictable and vary significantly from one period to another. If we are unable to predict the demand for AI or if we overestimate the demand for our products as a result of AI, our business may be adversely impacted. Furthermore, as a result of ongoing competition in the industries in which we operate and volatility in various economies around the world, we may achieve reduced market share, a reduced number of licenses or may experience tightening of customers’ operating budgets, difficulty or inability of our customers to pay our licensing fees, reduction in downstream demand, lengthening of the approval process for new products and licenses and consolidation among our customers. All of these factors may adversely affect the demand for our products and technologies and may cause us to experience substantial fluctuations in our operating results and financial condition.

Previous wording

We have a high degree of revenue concentration. Our top five customers for each reporting period represented approximately 70% and 71% of our consolidated revenue for the three months ended March 31, 2026 and 2025, respectively. Additionally, our top five customers for each reporting period represented approximately 66% and 62% of our consolidated revenue for the years ended December 31, 2025 and 2024, respectively. We expect to continue to experience significant revenue concentration for the foreseeable future. Our customers’ demand for our products may fluctuate due to factors beyond our control. We could experience fluctuations in our customer base or the mix of revenue by customer as markets and strategies evolve. A disruption in our relationship with any of our customers could adversely affect our business. In addition, any consolidation of our customers could reduce the number of customers to whom our products may be sold or the demand for our products. Our inability to meet our customers’ requirements or to qualify our products with them could adversely impact our revenue. The loss of, or restrictions on our ability to sell to, one or more of our major customers or any significant reduction in orders from, or a shift in product mix by customers, could have a material adverse effect on our operating results and financial condition.

Previous wording

As we commercially launch each of our products, the sales volume of and resulting revenue from such products in any given period will be difficult to predict. Our lengthy license negotiation cycles could make a considerable portion of our future revenue difficult to predict because we may not be successful in entering into or renewing licenses with our customers on our anticipated timelines.

Previous wording

Because we provide memory interface chips, among others, that are used in end products and systems, demand for our products is influenced by the demand for end products sold by our customers or via distributors. For example, we are currently experiencing increased demand for our products that is attributed to an increased demand for AI-based solutions, but we cannot predict future trends in such demand. As a result, we may have difficulty in accurately forecasting our product revenue. Our product revenue depends on the timing, scale and speed of introductions of new end products and systems, as well as the ongoing demand for existing end products and systems, that incorporate our products, all of which are intrinsically difficult to forecast. In addition, demand for our products is influenced by the ability of our customers and distributors to manage their inventory. If our customers and distributors do not manage their inventory correctly or misjudge their customers’ demand, our shipments to and orders from our customers and distributors may vary significantly, and we may have difficulty forecasting our inventory levels, which could reduce our product revenue, result in inventory write-offs and adversely affect our financial condition and results of operations. For these reasons, our actual results may differ substantially from analyst estimates or our forecasts in any given quarter.

Attempts by others to gain unauthorized access to and disrupt our information technology systems and IP assets are becoming more sophisticated. These attempts, which might be related to industrial or other espionage, may include (to Rambus, our customers and/or our third-party service providers), covertly introducing malware to our computers and networks and impersonating authorized users, phishing attempts and other forms of social engineering, employee or contractor malfeasance, denial of service attacks and ransomware attacks, among others. We seek to detect and investigate all security incidents impacting our systems and to prevent their recurrence, but in some cases, we might be unaware of an incident or its magnitude and effects. We also utilize third-party service providers to host, transmit or otherwise process electronic data in connection with our business activities, including our supply chain processes, operations and communications. Our customers also often have access to and host our confidential IP and business information on their own internal and directed third-party systems. Our data, corporate systems, third-party systems and security measures and those of our customers or the third parties that support us or our services may be subject to breaches or intrusions due to the actions of outside parties, employee error, malfeasance, a combination of these or otherwise, including social engineering and employee and contractor error or malfeasance, especially as certain of our employees engage in work from home arrangements. As a result, an unauthorized party may obtain access to our systems, networks or data, including IP and confidential business information of ourselves, our customers and/or the third parties that support us. There have been and may continue to be significant supply chain attacks, and we cannot guarantee that our or our third-party service providers’ systems and networks have not been breached or that they do not contain exploitable defects or bugs that could result in a breach of or disruption to our systems and networks or the systems and networks of our customers or of third parties that support us and our services. Geopolitical tensions, instability and conflicts may increase the cybersecurity risks that we, our customers and the third parties that support us face. We and our service providers may face difficulties or delays in identifying or responding to any actual or perceived security breach or incident. The theft or other unauthorized acquisition of, unauthorized use, publication or other processing of or access to our IP and/or confidential business information could harm our competitive position and reputation, reduce the value of our investment in research and development and other strategic initiatives or otherwise adversely affect our business. In the event of any security breach or incident, including any breach or incident that results in inappropriate access to, or loss, corruption, unavailability…

Our business operations depend on our ability to maintain and protect our facilities, computer systems and personnel, which are primarily located in the San Francisco Bay Area in the United States, Bulgaria, Canada, France, India, the Netherlands, South Korea and Taiwan. The San Francisco Bay Area is in close proximity to known earthquake fault zones and sites of recent historic wildfires. Our facilities and transportation for our employees are susceptible to damage from earthquakes and other natural disasters such as fires, floods, droughts, extreme temperatures and similar events. Should a catastrophe disable our facilities, we do not have readily available alternative facilities from which we could conduct our business, so any resultant work stoppage could have a negative effect on our operating results. We also rely on our network infrastructure and technology systems for operational support and business activities which are subject to physical and cyber damage, and also susceptible to other related vulnerabilities common to networks and computer systems.

The Organization for Economic Cooperation and Development (“OECD”) has proposed imposing a 15% global minimum tax under the Pillar Two Model Rules (“Pillar Two”), and this proposal has been adopted or is being considered by a number of countries. Additionally, on June 28, 2025, the G7 released a joint statement that it had reached an understanding with the United States for a side-by-side system based on certain accepted principles, including that U.S.-parented groups, such as ours, would be exempt from certain provisions of Pillar Two. In January 2026, the OECD released additional Administrative Guidance introducing new permanent safe harbors, including a Simplified Effective Tax Rate Safe Harbour and a Side-by-Side Safe Harbour, that are intended to reduce compliance burdens during Pillar Two implementation. These developments may further reduce compliance requirements and clarify how U.S.-parented groups are treated under the global minimum tax framework. However, any Pillar Two tax law changes, including these two Safe Harbours, are subject to legislative enactment by foreign jurisdictions. The potential effects of Pillar Two may vary depending on the specific provisions implemented by each jurisdiction, and could affect our effective tax rate and our operating results.

We are subject to a variety of laws and regulations in the United States, the European Union and other jurisdictions that involve, for example, user privacy, data protection and security, content, consumer protection and “conflict minerals” disclosure. Privacy and data protection regimes implemented in the European Union, the United Kingdom, California and other jurisdictions have been enacted that include penalties for noncompliance that potentially could run into the tens of millions of dollars. Other jurisdictions, including numerous states, countries and the U.S. federal government, are also contemplating such legislation. Existing and potential future laws and regulations relating to these matters may require us to modify our practices with respect to the collection, use, disclosure and other processing of data. Existing and proposed laws and regulations relating to these matters can be costly and challenging to comply with and can delay or impede the development of new products, result in negative publicity, increase our operating costs and subject us to claims or other remedies.
