🏢 1. Business Overview

Costco Wholesale Corporation (NASDAQ: COST) is one of the world’s largest membership-based warehouse retailers. Instead of operating traditional supermarkets or department stores, Costco sells a wide range of products in large quantities at low prices through a membership model. Customers pay an annual membership fee to shop at Costco warehouses, allowing the company to generate stable recurring revenue while maintaining relatively low product markups.

Founded in 1983 and headquartered in Issaquah, Washington, Costco has expanded into multiple international markets while maintaining a simple operating philosophy: offer high-quality merchandise at the lowest possible prices. The company limits the markup it places on products, relying on high sales volume, efficient operations, and membership income rather than maximizing profit on each item sold.

Investment Insight: Costco’s business model is designed to maximize customer loyalty instead of maximizing profit on every transaction. This creates a durable competitive advantage that has supported decades of consistent growth.

🛒 How Costco Makes Money

Costco generates revenue from two primary sources:

• Merchandise Sales — The vast majority of revenue comes from selling groceries, fresh foods, electronics, appliances, clothing, furniture, pharmacy products, gasoline, and many other everyday essentials.
• Membership Fees — Customers pay annual membership fees for access to Costco warehouses. These recurring fees provide highly predictable income and represent one of the company’s most valuable assets.

Unlike many traditional retailers, Costco intentionally keeps product prices low by limiting markups. This encourages customers to visit stores frequently and purchase larger quantities, resulting in high inventory turnover and strong operating efficiency.

🌎 Global Warehouse Network

Costco operates hundreds of membership warehouses across North America and several international markets. While the United States remains its largest business, international expansion continues to become a more meaningful contributor to long-term growth.

As of fiscal year 2025, Costco operates warehouses in:

• United States
• Canada
• Mexico
• United Kingdom
• Japan
• South Korea
• Taiwan
• Australia
• Spain
• France
• Iceland
• China
• New Zealand
• Sweden

The company also operates rapidly growing e-commerce platforms in many of these markets, allowing members to shop both online and in physical warehouses.

📦 What Does Costco Sell?

Costco offers a carefully selected assortment of merchandise instead of stocking hundreds of thousands of products like many retailers. This strategy helps the company negotiate better prices with suppliers and simplify warehouse operations.

Major merchandise categories include:

• Fresh foods and groceries
• Electronics and appliances
• Health and beauty products
• Pharmacy services
• Gasoline
• Furniture and home goods
• Jewelry and luxury items
• Sporting goods
• Seasonal merchandise
• Business supplies

Costco is also well known for Kirkland Signature, its private-label brand. A private-label brand is a product sold under the retailer’s own name rather than a third-party manufacturer. Kirkland Signature has developed a strong reputation for offering premium quality at competitive prices and plays an important role in customer loyalty.

💳 The Membership Advantage

Membership is the foundation of Costco’s business model. Customers must purchase an annual membership before shopping at most Costco warehouses.

This creates several advantages:

• Predictable recurring revenue from annual membership renewals
• Strong customer loyalty and repeat visits
• Stable cash flow regardless of short-term retail cycles
• The ability to maintain consistently low product prices

Costco has historically maintained very high membership renewal rates, demonstrating the value members receive from the company’s pricing and shopping experience.

⚙️ Why Costco’s Business Model Is Different

Many retailers attempt to maximize profit on every product they sell. Costco takes a different approach by keeping merchandise margins relatively low while focusing on operational efficiency and recurring membership income.

Several factors support this strategy:

• Limited product selection reduces inventory complexity.
• Large warehouse stores improve operating efficiency.
• High inventory turnover allows products to sell quickly.
• Strong supplier relationships help secure competitive pricing.
• Membership income provides a stable earnings base.

Why Investors Care: Costco’s recurring membership fees help make earnings more predictable than those of many traditional retailers, while efficient operations support consistent long-term profitability.

🧠 Plain English

If you’re new to investing, here’s the simplest way to think about Costco:

Costco isn’t just a retailer—it operates more like a membership club. Customers pay every year for the right to shop there, and because prices are kept low, members continue renewing their memberships. Those recurring membership fees provide steady income, while warehouse efficiency allows Costco to sell products at competitive prices without sacrificing profitability.

For long-term investors, this combination of recurring membership revenue, loyal customers, efficient operations, and disciplined pricing is what makes Costco one of the highest-quality retail businesses in the world.

EPS	14.2	16.6	18.2

💡 Plain English

Costco continued to deliver strong and consistent financial growth in FY2025. Total revenue increased from $254.5 billion to $275.2 billion, driven by higher warehouse sales, continued membership growth, and resilient consumer demand.

Gross profit grew faster than revenue, increasing from $32.1 billion to $35.3 billion. This indicates Costco maintained healthy merchandise profitability while expanding sales volume, despite inflationary pressures and higher operating costs.

Selling, General and Administrative (SG&A) expenses rose to $25.0 billion, mainly reflecting warehouse expansion, higher employee compensation, and ongoing investments in operations. However, operating income still increased nearly 12%, showing that revenue growth comfortably outpaced operating expense growth.

Pretax income reached $10.8 billion, while net income increased to $8.1 billion. Diluted earnings per share (EPS) also climbed from $16.6 to $18.2, demonstrating that Costco generated more profit for shareholders without relying on significant share dilution.

Overall, the income statement reflects a business that continues to grow steadily through higher sales, disciplined cost control, and a highly predictable membership-based business model rather than aggressive price increases.

Quick Ratio (%)	57.3%	43.9%	54.6%
Fixed Asset to Long-term Capital Ratio (%)	88.4%	100.0%	98.0%

💡 Plain English

Costco’s profitability remained exceptionally strong throughout FY2025. Gross margin improved to 12.8%, while operating margin expanded to 3.8%. Although these margins may appear low compared with many industries, this is completely normal for Costco’s low-price warehouse retail model. The company intentionally keeps product markups low to attract members and drive higher sales volume.

Returns on capital remained outstanding. ROE of 27.8%, ROTC of 26.8%, and ROIC of 33.3% indicate that Costco continues generating strong profits relative to the capital invested in the business. These are unusually high returns for a large global retailer and reflect disciplined operations and efficient capital allocation.

Leverage also remained conservative. The Debt-to-Equity ratio declined to 34.0%, showing that shareholders’ equity grew faster than debt. Even more importantly, Net Debt / EBITDA remained negative, meaning Costco held more cash than total debt. This gives the company significant financial flexibility during economic slowdowns.

Liquidity remained healthy as well. The Current Ratio stayed above 1.0x (103.4%), indicating current assets exceeded current liabilities, while the Quick Ratio improved meaningfully from the previous year as cash balances increased substantially.

Perhaps the most impressive figure is Costco’s Interest Coverage Ratio of 67.4x. This means operating income covered annual interest expense more than sixty-seven times, suggesting debt servicing represents only a very small financial burden for the company.

Equity
Common Equity	25,058	23,622	29,164
Total Liabilities + Equity	68,994	69,831	77,099

💡 Plain English

Costco finished FY2025 with an even stronger balance sheet. Total assets increased to $77.1 billion, supported primarily by higher cash balances and continued investment in new warehouses and distribution infrastructure. Cash and cash equivalents climbed sharply from $9.9 billion to $14.2 billion, giving Costco one of the strongest liquidity positions among global retailers.

Inventory declined slightly despite higher sales, falling from $18.6 billion to $18.1 billion. This is a positive sign because it suggests Costco sold merchandise efficiently without allowing inventory to accumulate faster than customer demand. Strong inventory management is especially important for retailers because excess inventory can lead to markdowns and lower profitability.

Property, Plant & Equipment increased to nearly $31.9 billion, reflecting continued investment in new warehouse openings, logistics facilities, and other long-term infrastructure. These investments support Costco’s long-term growth strategy rather than short-term earnings.

Total liabilities increased only modestly, while shareholders’ equity rose substantially to $29.2 billion. As a result, Costco’s financial position became even stronger, with equity growing faster than liabilities. Long-term debt remained relatively stable, and the company continued to maintain a conservative capital structure supported by a large cash balance.

Overall, Costco’s balance sheet demonstrates a financially healthy company with strong liquidity, manageable debt levels, disciplined inventory management, and continued investment for future growth.

Cash Flow Statement Summary

Unit: $m

Cash Flow Statement Summary	FY2023	FY2024	FY2025
Cash Flow from Operating Activities	11,068	11,339	13,335
Cash Flow from Investing Activities	(4,972)	(4,409)	(5,311)
Cash Flow from Financing Activities	(2,614)	(10,764)	(3,775)
Net Change in Cash	3,497	(3,794)	4,255
Beginning Cash Balance	10,203	13,700	9,906
Ending Cash Balance	13,700	9,906	14,161

💡 Plain English

Costco generated exceptionally strong operating cash flow in FY2025. Cash generated from day-to-day operations increased to $13.3 billion, the highest level in the three-year period. This reflects higher earnings, efficient working capital management, and the continued strength of Costco’s membership-based business model.

Investing cash outflows increased to $5.3 billion, primarily because Costco continued investing aggressively in new warehouses, distribution centers, and other long-term infrastructure. Rather than signaling weakness, these higher capital expenditures demonstrate management’s confidence in future growth opportunities.

Financing activities resulted in a $3.8 billion cash outflow. During the year, Costco continued returning capital to shareholders through dividends and share repurchases while also making scheduled debt repayments. Unlike FY2024, financing cash outflows were significantly lower because FY2024 included an unusually large special dividend.

As a result of strong operating cash generation exceeding both capital investments and shareholder distributions, Costco’s cash balance increased by more than $4.3 billion, ending the fiscal year with $14.2 billion in cash and cash equivalents. This substantial cash reserve provides the company with considerable financial flexibility for future expansion, capital investments, and additional shareholder returns.

🎯 Beginner Takeaways

• Costco continued to grow steadily in FY2025. Revenue increased to $275.2 billion, while net income reached a record $8.1 billion. This shows the business continued attracting more shoppers and members despite a challenging retail environment.
• Profitability improved across the board. Gross margin, operating margin, and pretax margin all expanded modestly. Costco’s margins remain lower than many retailers because its strategy focuses on offering members the lowest possible prices rather than maximizing product markups.
• Returns on capital remained outstanding. ROE, ROA, ROTC, and ROIC all remained at levels that many large companies struggle to achieve. This suggests management continues using shareholder capital very efficiently.
• The balance sheet became even stronger. Cash and cash equivalents increased to more than $14.2 billion, while debt remained stable. Costco continues operating with a conservative financial structure and has more than enough liquidity to fund future expansion.
• Cash generation remains one of Costco’s biggest strengths. Operating cash flow exceeded $13.3 billion, allowing the company to invest heavily in new warehouses while still returning billions of dollars to shareholders through dividends and share repurchases.
• Warehouse expansion continues to drive long-term growth. Capital expenditures remained elevated as Costco invested in new warehouse locations, logistics infrastructure, and technology. These investments are intended to support future sales rather than short-term earnings.
• The membership model continues to provide stability. Unlike many retailers that depend solely on merchandise sales, Costco also generates recurring membership fee income. This recurring revenue makes earnings more predictable and helps support customer loyalty during different economic environments.
• Overall, FY2025 demonstrates why Costco is widely viewed as one of the highest-quality retailers in the world. The company combined revenue growth, expanding profitability, strong free cash generation, disciplined capital allocation, and a fortress-like balance sheet, all while continuing to invest for long-term growth.

📈 3. Valuation

Here are the valuation ratios. These numbers don’t tell you by themselves if the stock is cheap or expensive. Investors typically compare them with peers, the broader market, or with their own view of intrinsic value (DCF). It’s up to each investor to judge whether these multiples signal undervaluation or overvaluation.

💵 Current Market Snapshot

• Current Share Price: $921.75
• Market Capitalization: $410.85 billion

Valuation Summary

Metric	Costco Wholesale Corporation
P/E	50.7x
Forward P/E	41.2x
P/B	14.1x
EV/EBITDA	31.4x
P/S	1.5x
Dividend Yield (%)	0.5%
Free Cash Flow Yield (%)	1.9%

💡 Plain English Recap

Costco’s P/E ratio of 50.7x means investors are paying about $50.70 for every $1 of FY2025 net income. Its lower Forward P/E of 41.2x reflects the market’s expectation that earnings will increase, although the stock still trades at a substantial earnings multiple.

The P/B ratio of 14.1x indicates that Costco’s market value is much higher than the accounting value of its shareholders’ equity. This commonly occurs when investors place significant value on assets that are not fully reflected on the balance sheet, such as the company’s membership base, brand reputation, customer loyalty, operating efficiency, and long-term growth record.

Costco’s EV/EBITDA ratio of 31.4x measures the value of the entire operating business relative to earnings before interest, taxes, depreciation, and amortization. The calculation uses enterprise value, which adds debt to market capitalization and subtracts cash. Costco’s large cash balance reduces enterprise value, but the resulting multiple remains high.

The P/S ratio of 1.5x means investors are valuing Costco at approximately $1.50 for every $1 of annual revenue. Because Costco generates enormous sales but operates with intentionally thin retail margins, its sales multiple should be considered together with profitability and cash-flow measures.

The company’s 0.5% dividend yield is relatively modest based on regular dividends declared during FY2025. Costco has also paid special dividends in some prior years, but those irregular distributions are not treated as a dependable annual dividend when evaluating the current yield.

The Free Cash Flow Yield of 1.9% is based on FY2025 operating cash flow of $13.3 billion minus $5.5 billion of capital expenditures. This means annual free cash flow represents about 1.9% of the company’s current market capitalization. A lower free cash flow yield generally indicates that investors are paying a higher price for the company’s current cash generation.

Overall, Costco’s valuation ratios show that the market assigns a significant premium to the company’s recurring membership revenue, high renewal rates, strong balance sheet, efficient operations, and consistent long-term growth. These qualities may help explain the premium, but investors must still decide whether the current valuation provides an adequate return relative to their own expectations and required margin of safety.

⚠️ 4. Risk

Editorial Note:
In order to enhance readability, we have omitted broad, market-wide risks that generally affect all companies. The following discussion is focused solely on the risks that are specific to this company and the warehouse retail industry.

🏬 Dependence on the Membership Model

Costco’s business model depends heavily on attracting new members while maintaining consistently high membership renewal rates. Membership fees represent a significant source of recurring revenue and help support the company’s strategy of offering merchandise at very low markups. If Costco fails to attract new members or existing members choose not to renew, sales growth, operating income, and overall financial performance could be negatively affected.

Executive Memberships are particularly important because these members generally spend more than standard members and account for a substantial portion of total merchandise sales. Maintaining the value proposition for both Executive and Gold Star members remains a key priority for the company.

• Recurring membership fees provide a stable source of revenue.
• High renewal rates are essential to maintaining customer loyalty.
• Executive Members contribute a significant share of merchandise sales.

Plain English: Costco is more than a retailer—it is also a membership business. If fewer customers join or renew their memberships, both sales and profits could be affected.

🏗️ Warehouse Expansion and Real Estate Execution

Costco’s long-term growth strategy relies on successfully opening new warehouses, expanding existing facilities, and investing in distribution infrastructure. This requires identifying attractive locations, obtaining permits and regulatory approvals, completing construction on schedule, and generating sufficient member demand after each warehouse opens.

The company notes that delays in construction, higher development costs, real estate availability, or weaker-than-expected sales at newly opened warehouses could reduce future growth. In addition, new warehouse openings may temporarily reduce sales at nearby existing locations as purchasing activity shifts between warehouses.

• Future revenue growth depends on successful warehouse expansion.
• Construction delays or cost overruns may reduce investment returns.
• New locations may temporarily shift sales away from nearby warehouses.

Plain English: Costco grows by opening new warehouses. If expansion slows or new locations perform below expectations, the company’s long-term growth could slow as well.

🌍 International Growth and Global Operations

Costco continues expanding outside the United States, with warehouses operating across North America, Europe, Asia, and Oceania. Managing a growing international business exposes the company to differences in local consumer preferences, regulations, labor markets, supply chains, taxation, and operating practices.

Successfully adapting its membership model and warehouse operations to different countries remains an important part of Costco’s long-term strategy. Difficulties entering new markets or managing existing international operations could reduce expected growth opportunities.

• International expansion is an important long-term growth driver.
• Local regulations and business environments differ across countries.
• Execution challenges could affect the success of overseas operations.

Plain English: Expanding into more countries creates new opportunities, but it also makes the business more complex to operate successfully.

🏷️ Merchandise Strategy and Supplier Relationships

Costco’s business model depends on offering high-quality merchandise at consistently low prices. To support this strategy, the company relies on maintaining strong relationships with suppliers while securing favorable purchasing terms and ensuring a steady supply of products. If Costco cannot obtain sufficient inventory, negotiate competitive pricing, or maintain product quality, its ability to deliver value to members could be negatively affected.

The company also depends on a relatively limited selection of products compared with traditional retailers. This merchandising strategy allows Costco to increase purchasing efficiency, but it also means that disruptions affecting key products or major suppliers could have a broader impact on warehouse operations.

• Strong supplier relationships help maintain competitive pricing.
• Consistent product quality is essential for member satisfaction.
• A limited merchandise assortment increases purchasing efficiency but also increases dependence on key suppliers.

Plain English: Costco promises members high-quality products at low prices. To keep that promise, it must maintain reliable suppliers and a steady flow of merchandise.

🚚 Supply Chain and Inventory Management

Costco operates one of the world’s largest warehouse retail networks, making efficient supply chain management critical to its business. The company depends on transportation providers, distribution centers, suppliers, and inventory systems to keep warehouses stocked with merchandise. Disruptions affecting any part of the supply chain could increase costs or reduce product availability.

The company also notes that maintaining appropriate inventory levels is important. Too little inventory may result in lost sales, while excess inventory could require markdowns or reduce operating efficiency.

• Efficient logistics support Costco’s low-cost business model.
• Inventory availability directly affects warehouse sales.
• Supply chain disruptions may increase costs or reduce merchandise availability.

Plain English: Costco’s warehouses need products arriving at the right place and the right time. Problems in the supply chain can make products harder to find and more expensive to sell.

💻 Information Technology and Cybersecurity

Costco relies extensively on information technology systems to manage warehouse operations, inventory, e-commerce, membership accounts, payment processing, and financial reporting. The company also stores sensitive information relating to members, employees, suppliers, and business operations.

Cyberattacks, unauthorized access, ransomware, system failures, or other technology disruptions could interrupt operations, expose confidential information, damage the company’s reputation, or result in legal and regulatory costs. Costco continues investing in cybersecurity and technology infrastructure to help manage these risks, but acknowledges that no system can eliminate them entirely.

• Technology systems support nearly every aspect of Costco’s operations.
• Cybersecurity incidents could disrupt business activities or expose sensitive information.
• Protecting member and employee data remains a critical operational priority.

Plain English: Costco depends on secure computer systems to run its warehouses and protect customer information. A major cyberattack could interrupt operations and harm customer trust.

👥 Workforce and Employee Retention

Costco’s operations depend on attracting, developing, and retaining a large workforce across its warehouses, distribution centers, business offices, and international operations. The company competes for qualified employees in a competitive labor market and emphasizes competitive wages, benefits, career development, and internal promotion. If Costco is unable to recruit or retain employees, maintain productivity, or effectively manage labor costs, its operations and customer service could be adversely affected.

• A large workforce is essential to warehouse operations.
• Employee retention and recruitment remain important for maintaining service quality.
• Competitive compensation and benefits are necessary to attract and retain talent.

Plain English: Costco depends on experienced employees to keep warehouses operating efficiently. Difficulty hiring or keeping workers could affect customer service and operating performance.

⚖️ Regulatory, Legal, and Compliance Risks

As a global retailer, Costco is subject to numerous laws and regulations covering areas such as employment practices, consumer protection, food safety, product quality, environmental requirements, privacy, pharmacy operations, and international business activities. The company is also involved in various legal proceedings and regulatory matters that arise in the normal course of business. Changes in regulations, compliance requirements, or unfavorable legal outcomes could increase operating costs or affect business operations.

• Operations are subject to extensive regulations across multiple countries.
• Legal proceedings are part of operating a large global retailer.
• Compliance failures could result in financial or operational consequences.

Plain English: Costco must comply with many different laws around the world. Failing to meet these requirements could increase costs or disrupt parts of its business.

🛡️ Brand Reputation and Customer Trust

Costco’s reputation is one of its most valuable assets. The company competes by offering high-quality merchandise, low prices, and a trusted shopping experience. Product quality issues, food safety incidents, cybersecurity events, supplier misconduct, or other events that damage customer confidence could negatively affect membership renewals, sales, and the Costco brand, including its Kirkland Signature private-label products.

• Customer trust supports membership renewals and repeat purchases.
• Kirkland Signature is an important part of Costco’s brand value.
• Reputation-related events could affect long-term customer loyalty.

Plain English: Costco’s reputation encourages customers to keep renewing their memberships. If that trust is damaged, members may decide to shop elsewhere.

✅ Summary of Risks

Costco’s company-specific risks are closely tied to its unique membership warehouse business model. The company depends on maintaining strong membership renewal rates, executing warehouse expansion successfully, building reliable supplier relationships, operating an efficient supply chain, protecting technology systems and customer information, retaining a skilled workforce, complying with a wide range of regulations, and preserving its reputation for quality and value. These factors represent the key business-specific risks identified by management and are central to Costco’s long-term operating strategy.

🧭 5. MD&A (Management’s Discussion and Analysis)

📋 Management Overview

Management explains that the primary purpose of the MD&A is to help investors better understand Costco’s financial condition and operating performance by providing additional context alongside the financial statements.

According to management, the company’s most important driver of profitability is increasing net sales, particularly comparable sales. Comparable sales measure revenue generated by warehouses and e-commerce operations that have been open for more than one year, making it an important indicator of underlying business performance rather than expansion through new warehouse openings.

Management states that comparable sales growth is primarily driven by two factors:

• Increasing shopping frequency by both new and existing members.
• Increasing the average amount spent during each shopping visit (average ticket).

Management also notes that reported sales can be affected by factors outside the company’s control, including foreign currency movements and changes in gasoline prices. To better evaluate operating performance, management often reviews comparable sales excluding these items.

💡 Plain English

Think of comparable sales as a way to measure how existing Costco warehouses are performing without being influenced by newly opened locations. Management believes this is the best indicator of whether members are shopping more often and spending more money.

📈 Revenue & Growth Drivers

Management states that net sales consist of several major business categories:

• Core merchandise, including foods, sundries, fresh foods, and non-food products.
• Warehouse ancillary businesses such as gasoline, pharmacy, optical, hearing aids, food courts, and tire installation.
• Other businesses including e-commerce, business centers, Costco Travel, and related operations.

Management explains that maintaining strong comparable sales allows the company to spread operating expenses across a larger revenue base. As sales increase faster than operating expenses, Selling, General and Administrative (SG&A) expenses become a smaller percentage of revenue, improving profitability.

Management further states that long-term sales growth depends on consistently offering the right merchandise at competitive prices while adapting product selection and pricing as market conditions change. Increasing the penetration of Kirkland Signature, Costco’s private-label brand, and expanding online offerings remain part of this strategy.

Management also emphasizes that overall economic conditions, competitive activity, inflation or deflation, and consumer spending patterns influence sales performance, although these factors are outside the company’s direct control.

💡 Plain English

Management says Costco grows by encouraging members to visit warehouses more frequently and spend more during each visit. Higher sales also make the business more efficient because many operating costs do not increase as quickly as revenue.

💼 Results of Operations

Management reported that total revenue increased to $275.2 billion in FY2025, primarily driven by higher net sales and continued growth in membership fee revenue. The company attributes this performance to positive comparable sales, new warehouse openings, and higher membership penetration.

Membership fee revenue increased during the year as Costco continued to add new members while maintaining strong renewal rates. Management considers membership fees an important contributor to overall profitability because they provide recurring revenue that supports the company’s low-price business model.

Operating income increased to $10.4 billion as revenue growth exceeded the increase in operating expenses. Management explains that SG&A expenses rose mainly because of warehouse expansion, employee compensation, and ongoing investments in operations, but these increases remained well supported by higher sales.

Management also notes that gross margin can fluctuate because of changes in merchandise mix, gasoline sales, foreign exchange movements, and the timing of certain merchandise promotions. Despite these factors, Costco continues focusing on maintaining competitive pricing while improving operating efficiency.

• Higher comparable sales supported revenue growth.
• Membership fee growth continued to strengthen recurring revenue.
• Operating income increased as sales grew faster than operating expenses.
• Merchandise mix and gasoline prices influenced reported margins during the year.

💡 Plain English

Management says FY2025 earnings improved because Costco sold more merchandise while continuing to attract and retain members. Although operating expenses increased, sales grew even faster, allowing profitability to improve.

💵 Liquidity & Capital Resources

Management states that Costco believes its existing cash balance, cash generated from operations, available short-term borrowing facilities, and ongoing operating cash flow will continue to provide sufficient liquidity to fund daily operations, warehouse expansion, capital expenditures, dividend payments, and other business needs.

Operating activities generated $13.3 billion of cash during FY2025, exceeding the previous fiscal year. Management explains that this strong operating cash flow reflects the company’s profitable operations and disciplined working capital management.

Capital expenditures increased as Costco continued investing in new warehouse locations, distribution facilities, technology systems, and warehouse improvements. Management indicates that these investments are intended to support future business growth rather than short-term financial performance.

The company also continued returning capital to shareholders through regular dividends and share repurchases while maintaining a conservative debt profile. Management believes its strong financial position provides flexibility to continue investing in long-term growth opportunities.

• Operating cash flow remained the primary source of liquidity.
• Capital expenditures focused on future warehouse growth.
• Cash was returned to shareholders through dividends and share repurchases.
• Management believes available liquidity is sufficient to support future operations and investment plans.

💡 Plain English

Management believes Costco generates enough cash every year to fund its business, open new warehouses, invest in technology, and reward shareholders without placing significant pressure on its financial position.

📊 Critical Accounting Estimates

Management explains that the preparation of the consolidated financial statements requires the use of accounting estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. While management believes these estimates are reasonable, actual results could differ if underlying assumptions change.

According to management, the most significant accounting estimates involve areas where judgment has the greatest impact on the financial statements, including:

• Merchandise inventories, including inventory valuation and estimated inventory shrink.
• Vendor consideration, such as rebates, discounts, and other purchasing incentives recognized as inventory costs or reductions of merchandise costs.
• Insurance and self-insurance liabilities, which require estimates of future claim costs.
• Income taxes, including deferred tax assets and liabilities as well as uncertain tax positions.
• Lease accounting, which requires assumptions about lease terms and discount rates.

Management states that these estimates are reviewed regularly and updated when new information becomes available.

💡 Plain English

Some financial statement numbers cannot be measured with complete precision. Management must estimate items such as future insurance claims, inventory adjustments, and income taxes. These estimates are based on the best information available at the time the financial statements are prepared.

🔮 Management Outlook

💡 Plain English

Management’s message is consistent throughout the MD&A: continue growing the business by opening more warehouses, keeping prices low, improving efficiency, and strengthening the membership program.

✅ Summary of MD&A

Management attributes Costco’s FY2025 performance primarily to higher comparable sales, continued membership growth, disciplined expense management, and strong operating cash flow. The company believes its recurring membership revenue, efficient warehouse operations, healthy liquidity, and ongoing investment in warehouses, technology, and logistics provide a solid foundation for future growth. Throughout the MD&A, management consistently emphasizes long-term execution, operational efficiency, and delivering value to members as the core priorities of the business.

✅ 6. Summary

Costco finished FY2025 with higher revenue, operating income, net income, and earnings per share, supported by continued sales growth and rising membership fee revenue. The company also generated strong operating cash flow while continuing to invest in new warehouses, logistics, technology, and other long-term infrastructure. Its balance sheet remained financially strong, with a large cash position, manageable debt, and higher shareholders’ equity.

The membership model remains central to Costco’s business because recurring fees support low merchandise markups, customer loyalty, and relatively predictable income. Management continues to focus on comparable sales growth, warehouse expansion, operational efficiency, and maintaining strong value for members. At the same time, Costco faces business-specific risks related to membership renewals, supply chain execution, international expansion, workforce management, cybersecurity, regulation, and brand trust.

Overall, Costco’s FY2025 results show a large retailer that continued to grow while preserving its low-price strategy, strong cash generation, and disciplined financial position. However, its valuation ratios indicate that investors are paying a substantial premium for those business qualities.
