- Our failure to maintain membership growth,
loyaltyloyalty, brand recognition, andbrand recognitionour culture could adversely affect our results of operations. - Membership loyalty and growth are essential to our business. The extent to which we achieve growth in our membership base, increase the penetration of Executive membership, and sustain high renewal rates materially influences our profitability. Achieving these metrics relies heavily on member trust and our long-standing culture focused on value, integrity, member service, and always striving to do what is right. Damage to our
brandsbrands, reputation, orreputationculture may negatively impact comparable sales, diminish member trust, and reduce renewal rates and, accordingly, net sales and membership fee revenue, negatively impacting our results of operations. - IT systems play a crucial role in conducting our business. These systems are utilized to, among other things, process a very high volume of transactions, conduct payment transactions, track and value our inventory, and produce reports critical for making business decisions. Failure or disruption of these systems could have an adverse impact on our ability to buy products and services from our suppliers, produce goods in our manufacturing plants, move products in an efficient manner to our warehouses, and sell products to our members. Given the high volume of transactions we process, it is important that we build strong resiliency to lessen disruption from events such as power outages, computer and telecommunications failures, viruses, internal or external security breaches and other cybersecurity incidents, errors by employees, extreme weather, and catastrophic events. Any debilitating failure of our critical IT systems, data centers, and backup systems would require significant investments in resources to restore services and may cause serious impairment in our business operations, including loss of business services, increased cost of moving merchandise and failure to provide service to our members. We are currently making substantial investments in technology and IT projects, including maintaining and enhancing our digital resiliency, and failure or delay in these projects could be costly and harmful to our business. We must also effectively monitor competitive technology trends, including the evolution of artificial intelligence (AI). Any failure to effectively incorporate these technologies could adversely affect our ability to compete. Additionally, the autonomous nature of AI presents unique challenges, particularly regarding third-party systems which may operate in ways that are difficult to monitor. There is a risk that these autonomous systems could bypass internal controls, lack adequate third-party governance, or result in unauthorized access to data, data leakage, and non-compliance with applicable data privacy laws. These systems may also produce inaccurate outputs, leading to unintended operational decisions. Failure to deliver IT projects efficiently and effectively could result in the loss of our competitive position and adversely impact our financial condition and results of operations. Insufficient IT capacity could also impact our capacity for timely, complete and accurate financial and non-financial reporting required by law.
- Increased security threats and more sophisticated cyber misconduct pose a risk to our systems, networks, products and services. We rely upon IT systems and networks, some of which are managed by or belong to third parties, including suppliers, partners, vendors, and service providers. Additionally, we collect, store, and process sensitive information relating to our business, members, employees, and other third parties. Operating these IT systems and networks and processing and maintaining this data in a secure manner are critical to our business operations and strategy. Remote work has also expanded possible attack surfaces. Attempts to gain unauthorized access to systems, networks, and data, both ours and third parties with whom we work, are increasing in frequency and sophistication, and in some cases, these attempts are successful. Cybersecurity attacks may range from random attempts to coordinated and targeted attacks, including sophisticated computer crimes and advanced persistent threats. Phishing attacks
have emerged asare particularly prominent, including as vectors for ransomware attacks, which have increased in breadth and frequency. While we train our employees as part of our security efforts, that training cannot be completely effective. The rapid evolution of AI has automated and accelerated the scale of cybersecurity threats, potentially reducing the time for us to detect and mitigate potential information security incidents. If our security infrastructure fails to keep pace with these evolving threats, it could lead to more frequent or sophisticated compromises of our systems, networks, or data, adversely affecting our operations and member confidence. These threats pose a risk to the security of our systems and networks and the confidentiality, integrity, and availability of our data. Our IT systems and networks, or those managed by third parties such as cloud providers or suppliers that otherwise host or have access to confidential information, periodically have vulnerabilities, which may go unnoticed for a period of time. Our logging capabilities, or the logging capabilities of third parties, are also not always complete or sufficiently detailed, affecting our ability to fully investigate and understand the scope of security events. While our cybersecurity and compliance efforts seek to mitigate such risks, there can be no guarantee that the actions and controls we and our third-party service providers have implemented and are implementing will be sufficient to protect our systems, information, or other property. - The potential impacts of a cybersecurity attack include reputational damage, litigation, government enforcement actions, penalties, disruption to systems and operations, unauthorized release of confidential or otherwise protected information, corruption of data, diminution in the value of our investment in IT systems, and increased cybersecurity protection and remediation costs. This could adversely affect our competitiveness, results of operations and financial condition and, critically in light of our business model, loss of member confidence. Further, the insurance coverage we maintain and indemnification arrangements with third parties may be inadequate to cover claims, costs, and liabilities relating to cybersecurity incidents. In addition, data we collect,
storestore, and process is subject to a variety of U.S. and international laws and regulations (such as the European Union General Data Protection Regulation, California Consumer Privacy Act, Health Insurance Portability and Accountability Act, and China's Personal Information Protection Act), evolving rules concerningartificial intelligence,AI, and other privacy and cybersecuritylaws and restrictions on use of member information that may also impair our ability to utilize data, consistent with member consents and preferences, which may carry significant potential penalties for noncompliance.laws. The use of AI carries risks related to the accuracy and reliability of its outputs. If these tools provide incorrect information to our members or our employees, or if the content generated inadvertently infringes upon the intellectual property rights of third parties, it could lead to reputational damage, legal claims, and increased regulatory scrutiny. Laws and restrictions on use of member information may also impair our ability to utilize data, consistent with member consents and preferences, which may carry significant potential penalties for noncompliance. - Our success depends on the continued contributions of our employees, including members of our senior management and other key operations, IT, merchandising, and administrative personnel. Failure to identify and implement a succession plan for senior management could negatively impact our business. We must attract,
traintrain, and retain a large and growing number of qualified employees, while controlling related laborcostscosts, preserving our culture, and maintaining our core values. Our ability to control labor and benefit costs is subject to numerous internal and external factors, including regulatory changes, prevailing wage rates, union relations, and healthcare and other insurance costs. We compete with other retail and non-retail businesses for these employees and invest significant resources in training and motivating them. There is no assurance that we will be able to attract or retain highly qualified employees in the future, which could have a material adverse effect on our business, financial condition and results of operations. - The retail business is highly competitive. We compete for members, employees, sites, products and services, and in other important respects with a wide range of local, regional and national wholesalers and retailers, both in the United States and in foreign countries, including other warehouse-club operators, supermarkets, supercenters, online retailers, gasoline stations, pharmacies, hard discounters, department and specialty stores and operators selling a single category or narrow range of merchandise or services. Such retailers and warehouse club operators compete vigorously and in a variety of ways, including pricing, selection and availability, services, location, convenience, store hours, and the attractiveness, and ease of use of websites and mobile applications. The evolution of retailing in online and mobile channels has improved the ability of customers to comparison shop, which has enhanced competition. Additionally, the emergence of AI tools may change consumer shopping habits and increase the competition we face. AI may also present inaccurate pricing or product data, or fail to capture the full value of our membership offering, impacting member purchasing decisions by prioritizing immediate or inaccurate price comparison or logistics over member loyalty. Some competitors have greater
financial resources andtechnology capabilities, including the faster adoption ofartificial intelligence, better access to merchandise,AI technologies, and greater market penetration than we do. Our inability to respond effectively to competitive pressures, changes in the retail markets or customer expectations could result in lost market share and negatively affect our financial results. - Higher energy and gasoline costs, inflation, levels of unemployment, healthcare costs, consumer debt levels, foreign-currency exchange rates, unsettled financial markets, weaknesses in housing and real estate markets, reduced consumer confidence, changes and uncertainties related to government fiscal, monetary, and tax policies including changes in interest rates, tax rates, duties, tariffs, or other restrictions, sovereign debt crises, pandemics and other health crises, and other economic factors could adversely affect demand for our products and services, require a change in product mix, or impact the cost of or ability to purchase inventory. Additionally, trade-related actions in various countries have adversely affected the costs of some of our merchandise. The degree of our exposure is dependent on (among other things) the type of goods, rates imposed, and timing of the tariffs and policy changes. The impact to our net sales and gross margin is influenced in part by our merchandising and pricing strategies in response to potential cost increases. Higher tariffs could adversely impact our results.
- Suppliers may be unable to timely
supplyprovide us with quality merchandise at competitive prices or may fail to adhere to our high standards, resulting in adverse effects on our business, merchandise inventories, sales, andprofit margins.profits. - Our suppliers (and those they depend upon for materials and services) are subject to risks, including labor disputes, union organizing activities, human
andrights violations, animalrightswelfare violations, financial liquidity, climate change, natural disasters, extreme weather conditions, environmental degradation, public health emergencies, supplyconstraintsconstraints, and general economic and political conditions and other risks similar to those we face that could limit their ability to timely provide us with acceptable merchandise. One or more of our suppliers might not adhere to our quality control, packaging, legal, regulatory, labor, human rights, environmental, or animal welfare standards. These deficiencies may delay or preclude delivery of merchandise to us and might not be identified before we sell such merchandise to our members. This failure could lead to recalls and litigation and otherwise damage our reputation and our brands, increase costs, and otherwise adversely impact our business. - The emergence, severity, magnitude, and duration of global or regional health crises are uncertain and difficult to predict. A pandemic could affect certain business operations, demand for our products and services, in-stock positions, costs of doing business, availability of labor, access to inventory, supply chain operations, our ability to predict future performance, exposure to litigation, and our financial performance, among other things. Other factors and uncertainties include, but are not limited to: the severity and duration of pandemics; evolving macroeconomic factors including general economic uncertainty, unemployment rates, and recessionary pressures; changes in labor markets affecting us and our suppliers; unknown consequences on our business performance and initiatives stemming from the substantial investment of time and other resources to the pandemic response; the pace of post-pandemic recovery; the long-term impact of the pandemic on our business, including consumer behaviors; and disruption and volatility within the financial and credit markets.
- We are subject to a wide and growing array of federal, state,
locallocal, and international laws and regulations relating to (among other things), product and food safety, marketing, information security and privacy, pricing, AI, labor and employment, imports and customs, transportation, intellectual property, anti-corruption, and environmental or social matters. These laws and regulations may expand mandatory reporting, increase the scope and complexity of matters that we are required to regulate, assess, and disclose, potentially limit our sourcing flexibility, or require extensive system or other changes that could increase the cost of doing business. Failure to comply could result in harm to our members, employees, workers in the value chain, or others, significant costs to satisfy environmental compliance, remediation or compensatory requirements, or the imposition of severe penalties or restrictions on operations by governmental agencies or courts that could adversely affect our business, financial condition and results of operations. - We are subject to risks associated with the legislative, judicial, accounting, regulatory, political and economic factors specific to the
countries or regions in whichplaces where we operate, which could adversely affect our business, financial condition and results of operations. - At the end of
2025,2026, we operated285292 warehouses outside of the U.S. (31% of all warehouse locations), and we plan to continue expanding our international operations. Future operating results internationally could be negatively affected by a variety of factors, many similar to those we face in the U.S., certain of which are beyond our control. These factors include political and economic conditions, regulatory constraints, currency regulations, policy changes, and other mattersin any of the countries or regions in whichwhere we operate, now or in the future. Other factors that may impact international operations include foreign trade (including tariffs and trade sanctions), monetary and fiscalpoliciespolicies, and the laws and regulations of the U.S. and foreign governments, agencies and similar organizations, international conflicts, and risks associated with having major facilities in locations which have been historically less stable than the U.S. Risks inherent in international operations also include, among others, the costs and difficulties of managing international operations, adverse tax consequences, and difficulty in enforcing intellectual property rights. New reporting obligations globally are increasing the cost and complexity of doing business. - We are subject to a variety of taxes and tax collection and remittance obligations related to federal, state, and foreign jurisdictions.
Additionally, atAt any point in time, wemay beare generally under examination for value added, sales-based, payroll, product,importimport, or other non-income taxes. We may recognize additional tax expense, be subject to additional tax liabilities, or incur losses and penalties, due to changes in laws, regulations, administrative practices, principles, assessments by authorities, and interpretations related to tax, including tax rules in various jurisdictions. We compute ourincome taxincome-tax provision based on enacted tax rates in the countries in which we operate. As tax rates vary among countries, a change in earnings attributable to the various jurisdictions in which we operate could result in an unfavorable change in our overall tax provision. Additionally, changes in the enacted tax rates or adverse outcomes in tax audits, including transfer pricing disputes, could have a material adverse effect on our financial condition and results of operations. - We are committed to doing what is right for the business, our members, employees, and shareholders over the long-term. Costco has set public targets and disclosed intentions for future action regarding sustainability. There are dependencies outside of our control impacting our ability to meet our goals, including but not limited to: economic conditions, ability to access technology at an appropriate cost or scale, the ability to procure sufficient clean energy at competitive market rates to meet future operational and supplier needs, unforeseen operational and implementation challenges, termination or contraction of policies or systems which support our capital investments, and collaboration with third parties. We may not make adequate and timely investments or successfully implement strategies that will effectively achieve our sustainability-related goals. Furthermore, international, federal,
statestate, and local regulatory authorities, private organizations and individuals may challenge our approach to ESG issues, including allegations that we failed in our efforts, should not have undertaken sucheffortsefforts, or that we improperly engaged other entities in our approach to ESG issues. A failure or perceived failure to meet our goals or otherwise meet evolving and diverse stakeholder expectations could lead to reputational harm.For example, multipleMultiple statesare implementinghave enacted or proposed extended producer responsibility lawsthat will requirerequiring us to enact policies and processes and will increase expenses in the form of fees paid to the state governments,else beor subject us to fines and penalties, among other effects. - Other factors and uncertainties include, but are not limited to:
- •The severity and duration of pandemics;
- •Evolving macroeconomic factors, including general economic uncertainty, unemployment rates, and recessionary pressures;
- •Changes in labor markets affecting us and our suppliers;
- •Unknown consequences on our business performance and initiatives stemming from the substantial investment of time and other resources to the pandemic response;
- •The pace of post-pandemic recovery;
- •The long-term impact of the pandemic on our business, including consumer behaviors; and
- •Disruption and volatility within the financial and credit markets.
- Our financial and operational performance is highly dependent on our U.S. and Canadian operations, which comprised 86% and
84%83% of net sales and operating income in2025.2026. Within the U.S., we are highly dependent on our California operations, which comprised 26% of U.S. net sales in2025.2026. Our California market, in general, has a larger percentage of higher volume warehouses as compared to our other domestic markets. Any substantial slowing or sustained decline in these operations could materially adversely affect our business and financial results. Declines in financial performance of our U.S. operations, particularly in California, and our Canadian operations could arise from, among other things: slow growth or declines in comparable warehouse sales (comparable sales); negative trends in operating expenses, including increased labor, healthcare, and energy costs; failing to meet targets for warehouse openings; cannibalizing existing locations with new warehouses; shifts in sales mix toward lower gross margin products; changes or uncertainties in economic conditions in our markets, including higher levels of unemployment and depressed home values; and failing to consistently provide high quality and innovative new products. - We accept payments using a variety of methods, including select credit and debit cards, cash and checks, co-brand cardholder rebates, Executive member
2%reward certificates, and our shop card. As we offer new payment options to our members, we may be subject to additional rules, regulations, compliance requirements, and higher fraud losses. For certain payment methods, we pay interchange and other related acceptance fees, along with additional transaction processing fees. We rely on third parties to provide payment transaction processing services for credit and debit cards and our shop card. It could disrupt our business if these parties become unwilling or unable to provide these services to us. We are also subject to fee increases by these service providers. - During
2025,2026, our international operations, including Canada, generated 27% and34%35% of our net sales and operating income. Our international operations have accounted for an increasing portion of our warehouses, and we plan to continue international growth. To prepare our consolidated financial statements, we translate the financial statements of our international operations from local currencies into U.S. dollars using current exchange rates. Future fluctuations in exchange rates that are unfavorable to us may adversely affect the financial performance of our Canadian and Other International operations and have a corresponding adverseperiod-over-periodeffect on our results of operations. As we continue to expand internationally, our exposure to fluctuations in foreign-exchange rates may increase.
