PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Refer to Note 13 – Contingencies of the Notes to Financial Statements (Part I, Item 1 of this Form 10-Q) for information regarding legal proceedings in which we are involved.

ITEM 1A. RI****SK FACTORS

Our operations and financial results are subject to various risks and uncertainties, including those described below, that could adversely affect our business, operations, financial condition, results of operations, liquidity, and the trading price of our common stock.

STRATEGIC AND COMPETITIVE RISKS

We face intense competition across all markets for our products and services, which could adversely affect our results of operations.

Competition in the technology sector

Our competitors range in size from diversified global companies with significant research and development resources to small, specialized firms whose narrower product lines may let them be more effective in deploying technical, marketing, and financial resources. Barriers to entry in many of our businesses are low and many of the areas in which we compete evolve rapidly with changing and disruptive technologies, shifting user needs, and frequent introductions of new products and services. If we do not continue to innovate and provide products, devices, and services that appeal to businesses and consumers, we may not remain competitive, which could adversely affect our business, financial condition, and results of operations.

Competition among platform-based ecosystems

An important element of our business model has been to create platform-based ecosystems on which many participants can build diverse solutions. A well-established ecosystem creates beneficial network effects among users, application developers, and the platform provider that can accelerate growth. Establishing significant scale in the marketplace is necessary to meet consumer demand and to achieve and maintain attractive margins. We face significant competition from firms that provide competing platforms.

A competing vertically-integrated model, in which a single firm controls the hardware and software elements of a product and related services, has succeeded with some consumer products such as PCs, tablets, smartphones, gaming consoles, wearables, and other endpoint devices. Competitors pursuing this model also earn revenue from services integrated with the hardware and software platform, including applications and content sold through their integrated marketplaces. They may also be able to claim security and performance benefits from their vertically-integrated offer. We also offer some vertically-integrated hardware and software products and services. Shifting a portion of our business to a vertically-integrated model may increase our cost of revenue and reduce our operating margins.

We derive substantial revenue from licenses of Windows operating systems on PCs. We face significant competition from competing platforms developed for new devices and form factors such as smartphones and tablets. These devices compete on multiple bases including price and the perceived utility of the device and its platform. Users continue to turn to these devices to perform functions that in the past were performed by PCs. Even if many users view these devices as complementary to a PC, the prevalence of these devices may make it more difficult to attract application developers to our PC operating system platforms. Competing with operating systems licensed at low or no cost may decrease our PC operating system margins. Popular products or services offered on competing platforms could increase their competitive strength. In addition, some of our devices compete with products made by our OEM partners, which may affect their commitment to our platform.

PART II

Item 1A

Competing platforms have content and application marketplaces with scale and significant installed bases. The variety and utility of content and applications available on a platform are important to device purchasing decisions. Users may incur costs to move data and buy new content and applications when switching platforms. To compete, we must successfully enlist developers to write applications for our platform and ensure that these applications have high quality, security, customer appeal, and value. Efforts to compete with competitors’ content and application marketplaces may increase our cost of revenue and lower our operating margins. Competitors’ rules governing their content and applications marketplaces may restrict our ability to distribute products and services through them in accordance with our technical and business model objectives.

For all of these reasons, we may not be able to compete successfully against our current and future competitors, which could adversely affect our business, operations, financial condition, and results of operations.

Business model competition

Companies compete with us based on a growing variety of business models.

A material part of our business involves cloud-based services available across the spectrum of computing devices. We and our competitors continue to devote significant resources to developing and deploying cloud-based strategies and services for consumers and business customers, and pricing and delivery models are evolving.

We are investing in artificial intelligence (“AI”) across the entire company and infusing generative AI capabilities into our consumer and commercial offerings. AI technology and services are a highly competitive and rapidly evolving market, and new competitors continue to enter the market. We will bear significant development and operational costs to build and support the AI models, services, platforms, and infrastructure necessary to meet the needs of our customers. To compete effectively we must also be responsive to technological change, new and potential regulatory developments, and public scrutiny.

Even as we transition more of our business to infrastructure-, platform-, and software-as-a-service business models, the license-based proprietary software model generates a substantial portion of our software revenue. We bear the costs of converting original ideas into software products through investments in research and development, offsetting these costs with the revenue received from licensing our products. Many of our competitors also develop and sell software to businesses and consumers under this model.

Other competitors develop and offer free applications, online services, and content, and make money by selling third-party advertising. Advertising revenue funds development of products and services these competitors provide to users at little or no cost, competing directly with our revenue-generating products.

Some companies compete with us by modifying and then distributing open-source software at little or no cost to end users, developing, making available, or using AI models that are open, and earning revenue on advertising or integrated products and services. These firms do not bear the full costs of research and development for the open-source products. Some open-source products mimic the features and functionality of our products.

The competitive pressures described above may cause decreased sales volumes, price reductions, and/or increased operating costs, such as for research and development, marketing, and sales incentives, which could adversely affect our financial condition and results of operations.

Our focus on cloud-based and AI services presents execution and competitive risks. We are incurring significant costs to build and maintain infrastructure to support cloud-based and AI services, reducing operating margins. Whether we succeed in cloud-based and AI services depends on our execution in several areas, including:

Continuing to bring to market compelling cloud-based and AI services and products that generate increasing traffic and market share.

Maintaining the utility, compatibility, and performance of our cloud-based and AI services on the growing array of computing devices, including PCs, smartphones, tablets, gaming consoles, and other devices.

Continuing to enhance the attractiveness of our cloud platforms to third-party developers.

PART II

Item 1A

Ensuring our cloud-based services meet the reliability expectations and specific requirements of our customers and maintain the security of their data as well as help them meet their own compliance needs.

Making our suite of cloud-based services platform-agnostic, available on a wide range of devices and ecosystems, including those of our competitors.

It is uncertain whether our strategies will continue to attract users or generate the revenue required to succeed. If we are not effective in executing organizational and technical changes to increase efficiency and accelerate innovation, or if we fail to generate sufficient usage of our new products and services, we may not grow revenue in line with the infrastructure and development investments described above. This could adversely affect our operations, financial condition, and results of operations.

Our AI systems offer users powerful tools and capabilities. However, there may be instances where these systems are used in ways that are unintended or inappropriate. In addition, some users may also engage in fraudulent or abusive activities through our cloud-based and AI services, such as unauthorized account access, payment fraud, or terms of service violations including cryptocurrency mining or launching cyberattacks. While we are committed to detecting and controlling such misuse of our cloud-based and AI services, our efforts may not be effective, and we may incur reputational damage or experience adverse impacts to our business and results of operations.

RISKS RELATING TO THE EVOLUTION OF OUR BUSINESS

We make significant investments in products and services that may not achieve expected returns. We will continue to make significant investments in research, development, and marketing for existing products, services, and technologies, including AI-based products and services. We also invest in the development and acquisition of a variety of hardware for productivity, communication, and entertainment, including PCs, tablets, and gaming devices. Investments in new technology are speculative. Commercial success depends on many factors, including innovation, developer support, and effective distribution and marketing. If customers do not perceive our latest offerings as providing significant new functionality or other value, they may reduce their purchases of new software and hardware products or upgrades, unfavorably affecting revenue. We may not achieve significant revenue from new product, service, and distribution channel investments for several years, if at all. New products and services may not be profitable or may not achieve operating margins as high as we have experienced historically. We may not get engagement in certain features that drive post-sale monetization opportunities. Our data-handling practices across our products and services will continue to be under scrutiny. Perceptions of mismanagement, driven by regulatory activity or negative public reaction to our practices or product experiences, could negatively impact product and feature adoption. Developing new technologies is complex. It can require long development and testing periods. We could experience significant delays in new releases or significant problems in creating new products or services. These factors could adversely affect our business, financial condition, and results of operations.

Acquisitions, joint ventures, and strategic alliances could have an adverse effect on our business. We expect to continue making acquisitions and entering into joint ventures and strategic alliances as part of our long-term business strategy. For example, in October 2023 we completed our acquisition of Activision Blizzard, Inc. In January 2023 we announced the third phase of our strategic partnership with OpenAI Global, LLC (“OpenAI”). Acquisitions and other transactions and arrangements involve significant challenges and risks, including that they do not advance our business strategy, that we get an unsatisfactory return on our investment, that they raise new compliance-related obligations and challenges, that we have difficulty integrating and retaining new employees, business systems, and technology, that they distract management from our other businesses, or that announced transactions may not be completed. If an arrangement fails to adequately anticipate changing circumstances and interests of a party, it may result in early termination or renegotiation of the arrangement. We also have limited ability to control or influence third parties with whom we have arrangements, which may impact our ability to realize the anticipated benefits. The success of these transactions and arrangements depend in part on our ability to leverage them to enhance our existing products and services or develop compelling new ones, as well as the acquired companies’ ability to meet our policies and processes in areas such as data governance, privacy, digital safety, responsible AI, and cybersecurity. It may take longer than expected to realize the full economic benefits from these transactions and arrangements, such as increased revenue or enhanced efficiencies, or the benefits may ultimately be smaller than we expected, which could cause an impairment of goodwill or intangibles. We have recorded, and may in the future be required to record, a significant charge in our consolidated financial statements during the period in which any impairment of our goodwill or amortizable intangible assets is determined, negatively affecting our results of operations. In addition, an acquisition may be subject to challenge even after it has been completed. These events could adversely affect our business, operations, financial condition, and results of operations.

Item 1A

CYBERSECURITY, DATA PRIVACY, AND PLATFORM ABUSE RISKS

Cyberattacks and security vulnerabilities could lead to reduced revenue, increased costs, liability claims, or harm to our reputation or competitive position.

Security of our information technology

Threats to security can take a variety of forms. Threat actors, including individual and groups of hackers and sophisticated organizations, including nation-states, state-sponsored organizations, or cybercriminal groups, continuously undertake attacks that pose threats to our customers and our internal infrastructure, and we have experienced cybersecurity incidents in which such actors have gained unauthorized access to our systems and data, including customer systems and data. These actors use a wide variety of methods, which include developing and deploying malicious software; exploiting known and potential vulnerabilities or intentionally designed processes in our or third-party hardware, software, or other infrastructure to attack our products and services or gain access to our networks and datacenters; using social engineering techniques to induce our employees, users, partners, or customers to disclose sensitive information, such as passwords, or take other actions to gain access to our data or our users’ or customers’ data; or acting in a coordinated manner or conducting coordinated attacks. For example, as previously disclosed in our Form 8-K filed with the Securities and Exchange Commission on January 19, 2024 and amended on March 8, 2024, beginning in late November 2023, a nation-state associated threat actor used a password spray attack to compromise a legacy test account and, in turn, gain access to Microsoft email accounts. The threat actor used information it obtained to gain unauthorized access to some of our source code repositories and internal systems, and the threat actor could continue to utilize this and other information to attempt to gain access to our systems or otherwise adversely affect our business and results of operations. This incident has and may continue to result in harm to our reputation and customer relationships. Nation-state and state-sponsored actors can sustain malicious activities for extended periods and deploy significant resources to plan and carry out attacks. Nation-state attacks against us, our customers, or our partners have and may continue to intensify due to our transparency to our customers, other stakeholders, and the public about cyberattacks, and during elections or periods of intense diplomatic or armed conflict. Challenges or failures in applying security patches to all hardware and devices connected to our systems, including end-of-life and end-of-support equipment, have and may continue to result in unauthorized access to our systems and data in the future. Cyber incidents and attacks, individually or in the aggregate, could adversely affect our financial condition, results of operations, competitive position, and reputation, or expose us to legal or regulatory risk.

Inadequate account security or organizational security practices, including those of companies we have acquired or those of the third parties we utilize, have resulted and may result in unauthorized access to our systems and data, including customer systems and data. For example, passwords may not be rotated and employee access may not be updated or removed on a timely basis. Employees or third parties may intentionally compromise our or our users’ security or systems or reveal confidential information, and laws in foreign jurisdictions may compel actions by such parties against our interests and could limit our recourse. Malicious actors may employ the supply chain to introduce malware through software updates or compromised supplier accounts or hardware.

Cyberthreats are constantly evolving and becoming increasingly sophisticated and complex, increasing the difficulty of detecting and successfully defending against them. Threat actors may also utilize emerging technologies, such as AI and machine learning. Our current capabilities may not detect certain vulnerabilities or new attack methods, which may allow them to persist in the environment over long periods of time. It may be difficult to determine the best way to investigate, mitigate, contain, and remediate the harm caused by a cyber incident. Such efforts may not be successful, and we may make errors or fail to take necessary actions. It is possible that threat actors may gain undetected access to other networks and systems after establishing a foothold on an internal system. Cyber incidents and attacks can have cascading impacts that unfold with increasing speed across our internal networks and systems, as well as those of our partners and customers. In addition, it may take considerable time for us to investigate and evaluate the full impact of incidents, particularly for sophisticated attacks. As a result of these and other factors, we may not be able to provide prompt, full, and reliable information about the incident to our customers, partners, regulators, and the public. Breaches of our facilities, network, or data security can disrupt the security of our systems and business applications, impair our ability to provide services to our customers and protect the privacy of their data, result in product development delays, compromise confidential or technical business information, result in theft or misuse of our intellectual property or other assets, subject us to ransomware attacks, require us to allocate more resources to improve technologies or remediate the impacts of attacks, or otherwise adversely affect our business. In addition, actions taken to remediate an incident could result in outages, data losses, and disruptions of our services.

PART II

Item 1A

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.
