Our internal environment continues to evolve. Often, we are early adopters of new devices and technologies. We embrace new ways of sharing data and communicating internally and with partners and customers using methods such as social networking and other consumer-oriented technologies. Increasing use of generative AI models in our internal or third-party systems may create new attack surfaces or methods for adversaries. Our business policies and internal security controls may not keep pace with these changes as new threats emerge or the emerging cybersecurity regulations in jurisdictions worldwide.
Security of our products, services, devices, and customers’ data
The security of our products and services is important in our customers’ decisions to purchase or use our products or services across cloud and on-premises environments. Security threats are a significant challenge to companies like us, whose business is providing technology products and services to others. Threats to or attacks on our own infrastructure, such as the nation-state attack described in the prior risk factor, have also affected our customers and may do so in the future. The reliability of our cloud-based services and the protection of customer data depend on the security of our infrastructure, which includes hardware, software, and other elements provided by third parties. Adversaries tend to focus their efforts on the most popular operating systems, programs, and services, including many of ours, as well as customers with sensitive data, and we expect that to continue. In addition, adversaries can attack our customers’ on-premises or cloud environments, sometimes exploiting previously unknown (“zero-day”) vulnerabilities. Product vulnerabilities can persist even after we have issued security patches if customers have not installed the most recent updates, or if the attackers exploited the vulnerabilities before patching to install additional malware to further compromise customers’ systems. Adversaries will continue to attack customers using our cloud services as customers embrace digital transformation. Adversaries that acquire user account information can use that information to compromise our users’ accounts, including where accounts share the same attributes such as passwords. Inadequate account security practices may also result in unauthorized access, and user activity may result in ransomware or other malicious software impacting a customer’s use of our products or services. Weaknesses in our development processes can result in vulnerabilities in our products. Open-source software can also contain vulnerabilities that may make our products susceptible to cyberattacks as we increasingly incorporate open-source software into our products. Additionally, features that rely on generative AI can be susceptible to security threats.
Our customers operate complex systems with third-party hardware and software from multiple vendors that may include systems acquired over many years. They expect our products and services to support all these systems and products, including those that no longer incorporate the strongest current security advances or standards. As a result, we may not be able to discontinue support of our services for a product, service, standard, or feature solely because a more secure alternative is available. Failure to utilize the most current security advances and standards can increase our customers’ vulnerability to attack. Further, customers of widely varied sizes and technical sophistication use our technology, and consequently may still have limited capabilities and resources to help them adopt and implement state-of-the-art cybersecurity practices and technologies. In addition, we must account for this wide variation of technical sophistication when defining default settings for our products and services, including security default settings, as these settings may limit or otherwise impact other aspects of operations and some customers may have limited capability to review and reset these defaults.
Cyberattacks could adversely impact our customers even if our production services are not directly compromised. We are committed to notifying our customers whose systems have been impacted as we become aware and have actionable information for customers to help protect themselves. We are also committed to providing guidance and support on detection, tracking, and remediation. We may not be able to detect the existence or extent of these attacks for all of our customers or have information on how to detect or track an attack, especially where an attack involves on-premises software such as Exchange Server where we may have no or limited visibility into our customers’ computing environments.
Any of the foregoing events could result in reputational harm, loss of revenue, increased costs, or otherwise adversely affect our business, financial condition, and results of operations.

PART II
Item 1A

Development and deployment of defensive measures
To defend against security threats to our internal infrastructure, our cloud-based services, and our customers’ systems, we must take a complex and multifaceted approach. This includes continuously engineering more secure products and services, and enhancing security, threat detection, and reliability features. We must also escalate and improve our development processes and the deployment of software updates to address security vulnerabilities in our own products as well as those provided by others in a timely manner. In addition, we must develop mitigation technologies that help to secure customers from attacks even when software updates are not deployed, and maintain the digital security infrastructure that protects the integrity of our network, products, and services. Further, we must provide security tools such as firewalls, anti-virus software, and advanced security and information about the need to deploy security measures and the impact of doing so.
The cost of these measures to protect products and customer-facing services could reduce our operating margins. If we fail to do these things well, actual or perceived security vulnerabilities in our processes, products, and services, data corruption issues, or reduced performance could harm our reputation and lead customers to exercise contractual or other remedies against us, reduce or delay future purchases of products or subscriptions to services, or to use competing products or services. Customers and third parties granted access to customer systems may fail to update their systems, continue to run software or operating systems we no longer support, may fail to timely install or enable security patches, or may otherwise fail to adopt adequate security practices. Customers may also spend more on protecting their existing computer systems from attack, which could delay adoption of additional products or services. Customers in certain industries such as financial services, health care, and government have enhanced or specialized expectations and requirements to which we must develop and engineer our products and services. Any of these could adversely affect our reputation and results of operations. Actual or perceived vulnerabilities may lead to claims against us. Our license agreements typically contain provisions that eliminate or limit our exposure to liability, but there is no assurance these provisions will withstand legal challenges. At times, to achieve commercial objectives, we may enter into agreements with larger liability exposure to customers.
Our products operate in conjunction with and are dependent on products and components across a broad ecosystem of third parties. If there is a security vulnerability in one of these components, and if there is a security exploit targeting it, we could experience adverse impacts to our results of operations, reputation, or competitive position.
Disclosure and misuse of personal data could result in liability and harm our reputation. As we continue to grow the number, breadth, and scale of our cloud-based offerings, we store and process increasingly large amounts of personal data of our customers and users. The continued occurrence of high-profile data breaches provides evidence of an external environment increasingly hostile to information security. Despite our efforts to improve the security controls across our business groups and geographies, it is possible our security controls over personal data, our training of employees and third parties on data security, and other practices we follow may not prevent the improper disclosure or misuse of customer or user data we or our vendors store and manage. Relatedly, despite our efforts to continuously improve security controls, it is possible that we may fail to identify or mitigate insider threat activities that could lead to the misuse of our systems or customer and user data. In addition, third parties who have limited access to our customer or user data may use this data in unauthorized ways. Improper disclosure or misuse could harm our reputation, lead to legal exposure to customers or users, or subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue. Our software products and services also enable our customers and users to store and process personal data on-premises or in a cloud-based environment we host. Government authorities can sometimes require us to produce customer or user data in response to valid legal orders. In the U.S. and elsewhere, we advocate for transparency concerning these requests and appropriate limitations on government authority to compel disclosure. Despite our efforts to protect customer and user data, perceptions that the collection, use, and retention of personal information is not satisfactorily protected could inhibit sales of our products or services and could limit adoption of our cloud-based solutions by consumers, businesses, and government entities. Additional security measures we take to address customer or user concerns, or constraints on our flexibility to determine where and how to operate datacenters in response to customer or user expectations or governmental rules or actions, may increase costs or hinder sales of our products and services.
We may not be able to protect information in our products and services from use by others. LinkedIn and other Microsoft products and services contain valuable information and content protected by contractual restrictions or technical measures. In certain cases, we have made commitments to our members and users to limit access to or use of this information. Changes in the law or interpretations of the law may weaken our ability to prevent third parties from scraping or gathering information or content through use of bots or other measures and using it for their own benefit which could adversely affect our business, financial condition, and results of operations.

PART II
Item 1A

Abuse of our platforms may harm our reputation or user engagement.
Advertising, professional, marketplace, and gaming platform abuses
For platform products and services that provide content or host ads that come from or can be influenced by third parties, our reputation or user engagement may be negatively affected by activity that is hostile or inappropriate. This activity may come from users impersonating other people or organizations, including through the use of AI technologies, dissemination of information that may be viewed as misleading or intended to manipulate the opinions of our users, or the use of our products or services that violates our terms of service or otherwise for objectionable or illegal ends. Preventing or responding to these actions may require us to make substantial investments in people and technology and these investments may not be successful, adversely affecting our business, financial condition, and results of operations.
Other digital safety abuses
Our consumer services as well as our enterprise services may be used to find, generate, store, or disseminate harmful or illegal content in violation of our terms or applicable law. We may not proactively discover such content due to scale, the limitations of existing technologies, and conflicting legal frameworks. When discovered by users and others, such content may negatively affect our reputation, our brands, and user engagement. Regulations and other initiatives have been enacted to make platforms responsible for preventing or eliminating harmful content online. At the same time, regulations and other initiatives regarding freedom of expression may conflict with such content moderation regulations. Further, duties to address risks to children are driving new obligations for age verification and parental controls across the online ecosystem, including within app stores and operating systems. The legal and regulatory environment in this area is complex and continues to evolve across multiple jurisdictions. As a result, there is considerable uncertainty regarding both current and future compliance obligations. Failure to comply with content requirements may subject us to enhanced regulatory oversight, civil or criminal liability, or reputational damage, which could adversely affect our business, financial condition, and results of operations.
Our products and services, how they are used by customers, and how third-party products and services interact with them, may present security, privacy, and execution risks. Our products and services may contain defects in design, manufacture, or operation that make them insecure or ineffective for their intended purposes. For example, customers control our products and services, including our AI products, within their environments, and may deploy them in high-risk scenarios or utilize them inappropriately. Our products may also collect large amounts of data in manners which may not satisfy customers or regulatory requirements. Our customers also operate complex systems with third-party hardware and software from multiple vendors whose products or personnel may take or fail to take actions which impact the reliability or security of our products and services. If our products and services do not work as intended, are utilized in methods not intended, violate the law, or harm individuals or businesses, we may be subject to legal claims or enforcement actions. These risks, if realized, may increase our costs, damage our reputation, or adversely affect our results of operations.

PART II
Item 1A

Issues in the development, deployment, and use of AI may result in reputational or competitive harm or liability. We are building AI into many of our offerings, including our productivity services, and we are also making AI available for our customers to use in solutions that they build. This AI may be developed by Microsoft or others, including our strategic partner, OpenAI. We expect these elements of our business to grow. We envision a future in which AI operating in devices, applications, and the cloud helps our customers be more productive in their work and personal lives. As with many innovations, AI presents risks and challenges that could affect its adoption, and therefore our business. AI algorithms or training methodologies may be flawed. Datasets may be overbroad, insufficient, or contain biased or inaccurate information. Content generated by AI systems may be offensive, illegal, inaccurate, or otherwise harmful. Ineffective or inadequate AI development or deployment practices by Microsoft or others could result in incidents that impair the acceptance of AI solutions, cause harm to individuals, customers, or society, or result in our products and services not working as intended. Human review of certain inputs and outputs or other forms of human oversight may be required, including for agentic AI systems that can take actions autonomously. Companion or highly-personalized AI systems may result in over-reliance or dependence by users that is harmful. Our implementation of AI systems could result in legal liability, regulatory action, brand, reputational, or competitive harm, or other adverse impacts. These risks may stem from issues related to intellectual property, data privacy, and other claims associated with AI training, outputs, and system behavior. They are further compounded by the evolving regulatory landscape, with new laws emerging globally, including the European Union (“EU”). Certain AI technologies and use cases present ethical issues or may have broad or uneven impacts on society or vulnerable groups within society. There is also rising divergence globally in how to address these issues and impacts, with the result that we will need to navigate a web of different tensions across geographies. If we enable or offer AI solutions that have unintended consequences, unintended usage or customization by our customers and partners, are contrary to our responsible AI policies and practices, or are otherwise controversial because of the impact on human rights, privacy, employment, or other social, economic, or political issues, our reputation, competitive position, business, financial condition, and results of operations could be adversely affected.
OPERATIONAL RISKS
We may have excessive outages, data losses, and disruptions of our online services if we fail to maintain an adequate operations infrastructure. Our increasing user traffic, growth in services, and the complexity of our products and services demand more computing power. We spend substantial amounts to build, purchase, or lease datacenters and equipment and to upgrade our technology and network infrastructure to handle more traffic on our websites and in our datacenters. Our datacenters depend on the availability of permitted and buildable land, predictable energy, networking supplies, and servers, including graphics processing units and other components. The cost or availability of these dependencies could be adversely affected by a variety of factors, including the transition to a clean energy economy, local and regional environmental regulations, and geopolitical disruptions. These demands continue to increase as we introduce new products and services and support the growth and the augmentation of existing services, including through the incorporation of AI features and/or functionality. We are rapidly growing our business of providing a platform and back-end hosting for services provided by third parties to their end users. Maintaining, securing, and expanding this infrastructure is expensive and complex, and requires development of principles for datacenter builds in geographies with higher safety and reliability risks. It requires that we maintain an Internet connectivity infrastructure and storage and compute capacity that is robust and reliable within competitive and regulatory constraints that continue to evolve. We also face community opposition, local moratoriums, and hyper-local dissent that may impede or delay infrastructure development. Inefficiencies or operational failures, including temporary or permanent loss of customer data, outages, insufficient Internet connectivity, insufficient or unavailable power or water supply, or inadequate storage and compute capacity could diminish the quality of our products, services, and user experience, resulting in contractual liability, claims by customers and other third parties, regulatory actions, damage to our reputation, and loss of current and potential users, subscribers, and advertisers, each of which could adversely affect our business, operations, financial condition, and results of operations.

PART II
Item 1A

We may experience supply or quality problems. There are limited suppliers for certain device and datacenter components. We continue to identify and evaluate opportunities to expand our datacenter locations and increase our server capacity to meet the evolving needs of our customers, particularly given the growing demand for AI services. Capacity available to us may be affected as competitors use some of the same suppliers and materials for hardware components. If components are delayed or become unavailable, whether because of supplier capacity constraint, industry shortages, legal or regulatory changes that restrict supply sources, or other reasons, we may not obtain timely replacement supplies, resulting in reduced sales or inadequate datacenter capacity to support the delivery and continued development of our products and services. Component shortages, excess or obsolete inventory, or price reductions resulting in inventory adjustments may increase our cost of revenue. Datacenter servers, Xbox consoles, Surface devices, and other hardware are assembled in Asia and other geographies that may be subject to disruptions in the supply chain, resulting in shortages which could adversely affect our business, operations, financial condition, and results of operations.
Our software products and services also have and may in the future experience quality or reliability problems. The processes we use to develop our software are imperfect. Like all software, our software contains bugs and other defects that interfere with their intended operation. Our customers increasingly rely on us for critical business functions and multiple workloads. Many of our products and services are interdependent on one another. Our products and services may be impacted by interaction with third-party products and services. Our customers may also utilize their own or third-party products and services whose reliability is dependent on interaction with our products and services. Each of these circumstances potentially magnifies the impact of quality or reliability issues. Weaknesses in our processes could result in defects we do not detect and fix in pre-release testing, which could cause reduced sales, damage to our reputation, repair or remediation costs, delays in the release of new products or versions, or legal liability, and could adversely affect our business, financial condition, and results of operations. Although our license agreements typically contain provisions that eliminate or limit our exposure to liability, there is no assurance these provisions will withstand legal challenge.
Our hardware products such as Xbox consoles, Surface devices, and other devices we design and market are highly complex. Failure to prevent, detect, or address defects in design, manufacture, or associated software could result in recalls, safety alerts, or product liability claims, which could adversely affect our business and results of operations.
LEGAL, REGULATORY, AND LITIGATION RISKS
We are subject to a variety of new, existing, and evolving legal and regulatory requirements that could adversely affect our results of operations. We are subject to a wide range of laws, regulations, and legal requirements in the U.S. and globally, including those that may apply to our products and online services offerings, and those that impose requirements related to user privacy, telecommunications, data storage and protection, digital accessibility, advertising, and online safety. Laws in several jurisdictions, including EU Member State laws under the European Electronic Communications Code, increasingly define certain of our services as regulated services. This trend may continue with our offerings becoming subject to additional data protection, security, digital safety, law enforcement surveillance, and other obligations. Regulators and private litigants may assert that our collection, use, and management of customer data and other information is inconsistent with their laws and regulations, including laws that apply to the tracking of users via technology such as cookies. In addition, laws requiring us to retrieve and produce customer data in response to compulsory legal demands from law enforcement and governmental authorities are expanding and the requests we are experiencing are increasing in volume and complexity.

PART II
Item 1A

New, existing, and evolving laws and regulations, or interpretations or applications of existing laws and regulations in a manner inconsistent with our interpretations of such laws and regulations or our practices, may result in modification of our products and services, altered business models and operations, increased costs, reputational damage, and civil or criminal liability. Examples include laws and regulations regarding:
• Competition laws and new market regulation: Government agencies closely scrutinize us under U.S. and foreign competition laws. Governments are actively enforcing competition laws and regulations and enacting new regulations to intervene in digital markets, and this includes markets such as the EU, the United Kingdom, the U.S., and China. Some jurisdictions also allow competitors or consumers to assert claims of anti-competitive conduct. U.S. and foreign antitrust authorities have previously brought enforcement actions and continue to scrutinize our business. Competition law enforcement actions and court decisions along with new market regulations may result in fines or hinder our ability to provide the benefits of our software to consumers and businesses, reducing the attractiveness of our products and the revenue that comes from them. New competition law actions or obligations under market regulation schemes could be initiated, potentially using previous actions as precedent.

• AI: Legislative and regulatory action is emerging in AI, which could increase costs or restrict opportunity. For example, the EU’s AI Act may increase costs or impact the provision or operation of our AI models and services in the European market. AI regulatory areas include model and system development and deployment, frontier model safety, transparency, and content provenance.

• Anti-corruption: The Foreign Corrupt Practices Act (“FCPA”) and other anti-corruption laws and regulations (“Anti-Corruption Laws”) prohibit corrupt payments by our employees, vendors, or agents, and the accounting provisions of the FCPA require us to maintain accurate books and records and adequate internal controls. From time to time, we receive inquiries from authorities in the U.S. and elsewhere which may be based on reports from employees and others about our business activities and our compliance with Anti-Corruption Laws. Periodically, we receive such reports directly and investigate them and also cooperate with investigations by U.S. and foreign law enforcement authorities.

• Trade: Increasing trade laws, policies, sanctions, and other regulatory requirements also affect our operations in and outside the U.S. relating to trade and investment. Economic sanctions in the U.S., the EU, and other countries prohibit most business with restricted entities or countries. U.S. export controls restrict Microsoft from offering many of its products and services to, or making investments in, certain entities in specified countries. U.S. import controls restrict us from integrating certain information and communication technologies into our supply chain and allow for government review of transactions involving information and communications technology from countries determined to be foreign adversaries. Supply chain regulations may impact the availability of goods or result in additional regulatory scrutiny. Restrictions on data flows and outbound investment and customer sensitivities may limit our ability to leverage parts of our global engineering footprint to provide services in certain jurisdictions. Increased geopolitical instabilities and changing U.S. Administration priorities create an unpredictable trade landscape. U.S. tariff and shifting AI export controls policies, like the AI Diffusion Rule, could increase operational costs, create uncertainty in the continuity of our products, and accelerate sovereignty initiatives among international partners and customers. The volatility of U.S. tariffs has triggered economic uncertainty and could impact cloud and devices supply chain cost competitiveness. The potential replacement of the recently rescinded AI Diffusion Rule and other potential AI-related rulemakings could adversely affect Microsoft’s business, strategy, and operations. Periods of intense diplomatic or armed conflict like the ongoing conflict in Ukraine and the Israel-Hamas conflict could result in (1) new and rapidly evolving sanctions and trade restrictions, which may impair trade with sanctioned individuals and countries, and (2) negative impacts to regional trade ecosystems among our customers, partners, and us.

• Cybersecurity: Legislative and regulatory actions related to cybersecurity may increase the costs associated with developing, implementing, or securing our products and services. The legal and regulatory environment in this area is complex and continues to evolve across multiple jurisdictions. As a result, there is considerable uncertainty regarding both current and future compliance obligations. This uncertainty increases the risk that we may incur additional operational costs, face regulatory enforcement actions, or encounter challenges in the development and deployment of our products.

PART II
Item 1A

• Handling of personal data: Legal requirements relating to the collection, storage, handling, and transfer of personal data globally continue to evolve. The growth of our Internet- and cloud-based services internationally relies on the movement of data across national boundaries. Data protection authorities and governments in the EU and other markets have and may again restrict and/or block the use of services that involve the transfer of data across borders. New and evolving rules and restrictions on the flow of data across borders could increase the cost and complexity of delivering our products and services. In addition, the EU General Data Protection Regulation and other similar regulations impose a range of compliance obligations regarding the handling of personal data. New requirements related to the use of data, including the Data Act, add additional rules and restrictions on the use of data in our products and services.

• Environmental, Social, and Governance: Laws, regulations, and policies relating to environmental, social, and governance matters are being developed and formalized in Europe, the U.S., and elsewhere, which may include greenhouse gas emissions and energy usage caps, as well as specific, target-driven environmental, social, and governance frameworks and disclosure requirements. In addition, in 2020 we announced goals to become carbon negative, water positive, and zero waste by 2030. Any failure or perceived failure to meet our sustainability goals, or to meet various sustainability regulatory requirements, could result in claims and lawsuits, regulatory actions, penalties, or damage to our reputation, each of which could adversely affect our business, operations, financial condition, and results of operations.

How these laws and regulations apply to our business is often unclear, subject to change, and sometimes may be inconsistent from jurisdiction to jurisdiction. In addition, governments’ approach to enforcement, and our products and services, are continuing to evolve. Compliance with existing, expanding, or new laws and regulations may involve significant costs and operational efforts, or require changes in products or business practices that could adversely affect our results of operations. Noncompliance could result in the imposition of penalties, criminal sanctions, or orders to cease the alleged noncompliant activity. If our products do not meet customer expectations or legal requirements, we could face regulatory or legal actions, and our business, operations, financial condition, and results of operations could be adversely affected.
We have claims and lawsuits against us that may result in adverse outcomes. We are subject to a variety of claims and lawsuits. These claims may arise from a wide variety of business practices and initiatives, including major new product releases, AI services, significant business transactions, warranty or product claims, employment practices, and regulation. As we continue to expand our business and offerings, we may experience new and novel legal claims. Adverse outcomes in some or all of these claims may result in significant monetary damages or injunctive relief that could adversely affect our ability to conduct our business. Litigation and other claims are subject to inherent uncertainties and management’s view of these matters may change in the future. An adverse impact to our financial condition and results of operations could occur for the period in which the effect of an unfavorable outcome becomes probable and reasonably estimable.
Our business with government customers may present additional uncertainties. We derive substantial revenue from government contracts. Government contracts and regulatory requirements can present risks and challenges not present in private commercial agreements. For instance, we are subject to government audits and investigations relating to these contracts, and we are required to provide assurance and attestations about our products and processes. If we do not satisfy contractual or regulatory requirements, we could be suspended or debarred as a governmental contractor, we could incur civil and criminal fines and penalties, and under certain circumstances contracts may be rescinded. Some agreements may allow a government to terminate without cause and provide for higher liability limits for certain losses. Some contracts may be subject to periodic funding approval, reductions, cancellations, or delays which could adversely impact public-sector demand for our products and services. These events could negatively impact our financial condition, results of operations, and reputation.

PART II
Item 1A

We may have additional tax liabilities. We are subject to income taxes in the U.S. and many foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We may recognize additional tax expense and be subject to additional tax liabilities due to changes in tax laws, regulations, and administrative practices and principles, including changes to the global tax framework, in various jurisdictions. In recent years, multiple domestic and international tax proposals were proposed to impose greater tax burdens on large multinational enterprises. For example, the Organisation for Economic Co-operation and Development continues to advance proposals or guidance in international taxation, including the establishment of a global minimum tax.
We are regularly under audit by tax authorities in different jurisdictions. Although we believe that our provision for income taxes and our tax estimates are reasonable, tax authorities may disagree with certain positions we have taken. In addition, economic and political pressures to increase tax revenue in various jurisdictions may make resolving tax disputes favorably more difficult. We are currently under IRS audit for prior tax years and have received Notices of Proposed Adjustment (“NOPAs”) from the IRS for the tax years 2004 to 2013. The primary issues in the NOPAs relate to intercompany transfer pricing. In the NOPAs, the IRS is seeking an additional tax payment of $28.9 billion plus penalties and interest. The final resolution of the proposed adjustments, and other audits or litigation, may differ from the amounts recorded in our consolidated financial statements and adversely affect our results of operations in the period or periods in which that determination is made.
We earn a significant amount of our operating income outside the U.S. A change in the mix of earnings and losses in countries with differing statutory tax rates, changes in our business or structure, or the expiration of or disputes about certain tax agreements in a particular country may result in higher effective tax rates for the company. In addition, changes in U.S. federal and state or international tax laws applicable to corporate multinationals, other global fundamental law changes currently being considered by many countries, including in the U.S., and changes in taxing jurisdictions’ administrative interpretations, decisions, policies, and positions could adversely affect our financial condition and results of operations.
INTELLECTUAL PROPERTY RISKS
We face risks related to the protection and utilization of our intellectual property that may result in our business and operating results being harmed. Protecting our intellectual property rights and combating unlicensed copying and use of our software, source code, and other intellectual property on a global basis is difficult. Similarly, the absence of harmonized patent laws makes it more difficult to ensure consistent respect for patent rights.
Changes in the law may continue to weaken our ability to prevent the use of patented technology. Our increasing engagement with open-source software will also cause us to license our intellectual property rights broadly in certain situations. If we are unable to protect our intellectual property, our results of operations could be adversely affected.
Source code, the detailed program commands for our operating systems and other software programs, is critical to our business. If our source code leaks, we might lose future trade secret protection for that code. It may then become easier for third parties to compete with our products by copying functionality, which could adversely affect our results of operations. Unauthorized access to or disclosure of source code or other intellectual property also increases the security risks described elsewhere in these risk factors.
Third parties may claim that we infringe their intellectual property. From time to time, others claim we infringe their intellectual property rights, including current copyright infringement and other claims arising from AI training and output. To resolve these claims, we may enter into royalty-bearing data access or licensing agreements on terms that are less favorable than currently available, stop selling or redesign affected products or services, or pay damages to satisfy indemnification commitments with our customers. Adverse outcomes could also include monetary damages or injunctive relief that may limit or prevent importing, marketing, and selling our products or services that have infringing technologies. We have paid significant amounts to settle claims related to the use of technology and intellectual property rights and to procure intellectual property rights as part of our strategy to manage this risk, and may continue to do so, which could adversely affect our results of operations.

PART II
Item 1A

GENERAL RISKS
If our reputation or our brands are damaged, our business and results of operations may be harmed. Our reputation and brands are globally recognized and are important to our business. Our reputation and brands affect our ability to attract and retain consumer, business, and public-sector customers. There are numerous ways our reputation or brands could be damaged. These include product safety or quality issues, our environmental impact and sustainability, supply chain practices, or human rights record. We may experience backlash from customers, government entities, advocacy groups, employees, and other stakeholders that disagree with our product offering decisions, public policy positions, or corporate philanthropic initiatives. Damage to our reputation or our brands may occur from, among other things:
• The introduction of new features, products, services, or terms of service that customers, users, or partners do not like.

• Public scrutiny of our decisions regarding user privacy, data practices, content, or development and deployment of AI.

• Data security breaches, cybersecurity incidents, responsible AI failures, compliance failures, or actions of partners or individual employees.

Social media may increase the likelihood, speed, and magnitude of negative brand events. If our brands or reputation are damaged, it could adversely affect our business, results of operations, or ability to attract the most highly qualified employees.
Adverse economic or market conditions could harm our business. Worsening economic conditions, including inflation, recession, pandemic, or other changes in economic conditions, may cause lower IT spending and adversely affect our results of operations. If demand for computing power, PCs, servers, and other computing devices declines, or consumer or business spending for those products declines, our results of operations could be adversely affected.
Our product distribution system relies on an extensive partner and retail network. OEMs building devices that run our software have also been a significant means of distribution. The impact of economic conditions on our partners, such as the bankruptcy of a major distributor, OEM, or retailer, could cause sales channel disruption.
Challenging economic conditions also may impair the ability of our customers to pay for products and services they have purchased. As a result, allowances for doubtful accounts and write-offs of accounts receivable may increase.
We maintain an investment portfolio of various holdings, types, and maturities. These investments are subject to general credit, liquidity, market, and interest rate risks, which may be exacerbated by market downturns or events that affect global financial markets. A significant part of our investment portfolio comprises U.S. government securities. If global financial markets decline for long periods, or if there is a downgrade of the U.S. government credit rating due to an actual or threatened default on government debt, our investment portfolio could be adversely affected and we could determine that more of our investments have experienced a decline in fair value, requiring impairment charges that could adversely affect our financial condition and results of operations.
Catastrophic events or geopolitical conditions could disrupt our business. A disruption or failure of our systems, operations, or supply chain because of a major earthquake, weather event, cyberattack, terrorist attack, pandemic, or other catastrophic event could cause delays in completing sales, providing services, or performing other critical functions. Our corporate headquarters, a significant portion of our research and development activities, and certain other essential business operations are in the Seattle, Washington area, and we have other business operations in the Silicon Valley area of California, both of which are seismically active regions. A catastrophic event that results in the destruction or disruption of any of our critical business or systems, or the infrastructure or systems they rely on, such as power grids, could harm our ability to conduct normal business operations or adversely affect our results of operations. Providing our customers with more services and solutions in the cloud puts a premium on the resilience of our systems and strength of our business continuity management plans and magnifies the potential negative consequences of prolonged service outages.

PART II
Item 1A

Abrupt political change, terrorist activity, and armed conflict, such as the ongoing conflict in Ukraine, pose economic and other risks, which may negatively impact our ability to sell to and collect from customers, increase our operating costs, or otherwise disrupt our operations in markets both directly and indirectly impacted by such events. These conditions also may add uncertainty to the timing and budget for technology investment decisions by our customers and may cause supply chain disruptions for hardware manufacturers. Geopolitical change may result in changing regulatory systems and requirements and market interventions that could impact our operating strategies, access to national, regional, and global markets, hiring, and profitability. Geopolitical instability may lead to sanctions and impact our ability to do business in some markets or with some public-sector customers. Any of these changes could adversely affect our results of operations. Changes in geopolitical conditions also increase the security risks described elsewhere in these risk factors.
The occurrence of regional epidemics or a global pandemic, such as COVID-19, could adversely affect our business, operations, financial condition, and results of operations. The extent to which global pandemics impact our business going forward will depend on factors such as the duration and scope of the pandemic; governmental, business, and individuals' actions in response to the pandemic; and the impact on economic activity, including the possibility of recession or financial market instability. Measures to contain a global pandemic may intensify other risks described in these Risk Factors.
The long-term effects of climate change on the global economy and the IT industry in particular are unclear. Environmental regulations or changes in the supply, demand, or available sources of energy or other resources may affect the availability or cost of goods and services, including natural resources, necessary to run our business. Changes in climate where we operate may increase the costs of powering and cooling computer hardware we use to develop software and provide cloud-based services.
Our global business exposes us to operational and economic risks. Our customers, employees, and infrastructure are located throughout the world and a significant part of our revenue comes from international sales. The global nature of our business creates operational, economic, and geopolitical risks. Global, regional, and local economic developments, monetary policy, geopolitical tension, particularly between the U.S. and Europe, restrictions on international trade, such as tariffs and other controls on imports or exports, inflation, and recession, as well as political and military disputes, could adversely affect our results of operations. Non-compliance with sanctions as well as general ecosystem disruptions could result in reputational harm, operational delays, monetary fines, loss of revenue, increased costs, loss of export privileges, or criminal sanctions, which could adversely affect our business, financial condition, and results of operations.
In addition, our international growth strategy includes certain markets, the developing nature of which presents several risks, including deterioration of social, political, labor, or economic conditions in a country or region, and difficulties in staffing and managing foreign operations. Emerging nationalist and protectionist trends and concerns about human rights, the environment, and political expression in specific countries may significantly alter the trade and commercial environments. Changes to trade policy or agreements as a result of populism, protectionism, or economic nationalism may result in higher tariffs, local sourcing initiatives, and non-local sourcing restrictions, export controls, investment restrictions, or other developments that make it more difficult to operate and sell our products in foreign countries. Disruptions of these kinds in developed or emerging markets could negatively impact demand for our products and services, impair our ability to operate in certain regions, or increase operating costs. Although we hedge a portion of our international currency exposure, significant fluctuations in foreign exchange rates between the U.S. dollar and foreign currencies could adversely affect our results of operations.

PART II
Item 1A

Our business depends on our ability to attract and retain talented employees. Our business is based on successfully attracting, training, and retaining talented employees representing diverse backgrounds, experiences, and skill sets. The market for highly skilled workers and leaders in our industry is extremely competitive. Maintaining our brand and reputation, as well as an inclusive work environment that enables all our employees to thrive, are important to our ability to recruit and retain employees. We are also limited in our ability to recruit internationally by restrictive domestic immigration laws. Restraints on the flow of technical and professional talent, including those derived from changes to U.S. immigration policies or laws, may inhibit our ability to adequately staff our research and development efforts. If we are less successful in our recruiting efforts, or if we cannot retain highly skilled workers and key leaders, our ability to develop and deliver successful products and services could be adversely affected. Effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution. How employment-related laws are interpreted and applied to our workforce practices may result in increased operating costs and less flexibility in how we meet our workforce needs. Our global workforce is predominantly non-unionized, although we do have some employees in the U.S. and internationally who are represented by unions or works councils. In the U.S., there has been a general increase in workers exercising their right to form or join a union. The unionization of significant employee populations could result in higher costs and other operational changes necessary to respond to changing conditions and to establish new relationships with worker representatives.
