> Costco maintained its overall risk factor framework with 37 unchanged risks alongside 37 substantively modified risks, while adding no new risk categories and removing none. The modifications focused primarily on financial reporting disclosures, including updates to fair value measurement methodologies, debt structures, lease accounting, tax treatments, and earnings per share calculations, alongside refinements to operational risk descriptions such as natural disasters and catastrophic events. No shifts in the fundamental risk landscape occurred, as Costco's material business exposures remained consistent between the two reporting periods.

This section generally discusses the results of operations for 2022 compared to 2021. For discussion related to the results of operations and changes in financial condition for 2021 compared to 2020 refer to Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations in our fiscal year 2021 Form 10-K, which was filed with the United States Securities and Exchange Commission (SEC) on October 6, 2021. Overview We believe that the most important driver of our profitability is increasing net sales, particularly comparable sales. Net sales includes our core merchandise categories (foods and sundries, non-foods, and fresh foods), warehouse ancillary (gasoline, pharmacy, optical, food court, hearing aids, and tire installation) and other businesses (e-commerce, business centers, travel and other). We define comparable sales as net sales from warehouses open for more than one year, including remodels, relocations and expansions, and sales related to e-commerce websites operating for more than one year. Comparable sales growth is achieved through increasing shopping frequency from new and existing members and the amount they spend on each visit (average ticket). Sales comparisons can also be particularly influenced by certain factors that are beyond our control: fluctuations in currency exchange rates (with respect to our international operations); inflation and changes in the cost of gasoline and associated competitive conditions. The higher our comparable sales exclusive of these items, the more we can leverage our SG&A expenses, reducing them as a percentage of sales and enhancing profitability. Generating comparable sales growth is foremost a question of making available to our members the right merchandise at the right prices, a skill that we believe we have repeatedly demonstrated over the long-term. Another substantial factor in net sales growth is the health of the economies in which we do business, including the effects of inflation or deflation, especially the United States. Net sales growth and gross margins are also impacted by our competition, which is vigorous and widespread, across a wide range of global, national and regional wholesalers and retailers, including those with e-commerce operations. While we cannot control or reliably predict general economic health or changes in competition, we believe that we have been successful historically in adapting our business to these changes, such as through adjustments to our pricing and merchandise mix, including increasing the penetration of our private-label items, and through online offerings. Our philosophy is to provide our members with quality goods and services at competitive prices. We do not focus in the short-term on maximizing prices charged, but instead seek to maintain what we believe is a perception among our members of our "pricing authority" - consistently providing the most competitive values. Merchandise costs in 2022 were impacted by inflation higher than what we have experienced in recent years. The impact to our net sales and gross margin is influenced in part by our merchandising and pricing strategies in response to cost increases. Those strategies can include, but are not limited to, working with our suppliers to share in absorbing cost increases, earlier-than-usual purchasing and in greater volumes, offering seasonal merchandise outside its season, as well as passing cost increases on to our members. Our investments in merchandise pricing may include reducing prices on merchandise to drive sales or meet competition and holding prices steady despite cost increases instead of passing the increases on to our members, all negatively impacting gross margin and gross margin as a percentage of net sales (gross margin percentage). We believe our gasoline business enhances traffic in our warehouses, but it generally has a lower gross margin percentage relative to our non-gasoline business. It also has lower SG&A expenses as a percent of net sales compared to our non-gasoline business. A higher penetration of gasoline sales will generally lower our gross margin percentage. Rapidly changing gasoline prices may significantly impact our near- 22 22 22 Table of Contents Table of Contents term net sales growth. Generally, rising gasoline prices benefit net sales growth which, given the higher sales base, negatively impacts our gross margin percentage but decreases our SG&A expenses as a percentage of net sales. A decline in gasoline prices has the inverse effect. Additionally, actions in various countries, particularly China and the United States, have 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. Higher tariffs could adversely impact our results. We also achieve net sales growth by opening new warehouses. As our warehouse base grows, available and desirable sites become more difficult to secure, and square footage growth becomes a comparatively less substantial component of growth. The negative aspects of such growth, however, including lower initial operating profitability relative to existing warehouses and cannibalization of sales at existing warehouses when openings occur in existing markets, are continuing to decline in significance as they relate to the results of our total operations. Our rate of square footage growth is generally higher in foreign markets, due to the smaller base in those markets, and we expect that to continue. Our e-commerce business growth, domestically and internationally, has also increased our sales but it generally has a lower gross margin percentage relative to our warehouse operations. E-commerce sales growth slowed in 2022 compared to 2021 and 2020. The membership format is an integral part of our business and has a significant effect on our profitability. This format is designed to reinforce member loyalty and provide continuing fee revenue. The extent to which we achieve growth in our membership base, increase the penetration of our Executive members, and sustain high renewal rates materially influences our profitability. Our paid membership growth rate may be adversely impacted when warehouse openings occur in existing markets as compared to new markets. Our financial performance depends heavily on controlling costs. While we believe that we have achieved successes in this area, some significant costs are partially outside our control, particularly health care and utility expenses. With respect to the compensation of our employees, our philosophy is not to seek to minimize their wages and benefits. Rather, we believe that achieving our longer-term objectives of reducing employee turnover and enhancing employee satisfaction requires maintaining compensation levels that are better than the industry average for much of our workforce. This may cause us, for example, to absorb costs that other employers might seek to pass through to their workforces. Because our business operates on very low margins, modest changes in various items in the consolidated statements of income, particularly merchandise costs and SG&A expenses, can have substantial impacts on net income. Our operating model is generally the same across our U.S., Canadian, and Other International operating segments (see Note 11 to the consolidated financial statements included in Item 8 of this Report). Certain operations in the Other International segment have relatively higher rates of square footage growth, lower wage and benefit costs as a percentage of sales, less or no direct membership warehouse competition, or lack e-commerce or business delivery. In discussions of our consolidated operating results, we refer to the impact of changes in foreign currencies relative to the U.S. dollar, which are the differences between the foreign-exchange rates we use to convert the financial results of our international operations from local currencies into U.S. dollars. This impact of foreign-exchange rate changes is calculated based on the difference between the current period's currency exchange rates and that of the comparable prior period. The impact of changes in gasoline prices on net sales is calculated based on the difference between the current period's average price per gallon sold and that of the comparable prior period. Our fiscal year ends on the Sunday closest to August 31. References to 2022, 2021, and 2020 relate to the 52-week fiscal years ended August 28, 2022, August 29, 2021, and August 30, 2020, respectively. Certain percentages presented are calculated using actual results prior to rounding. Unless otherwise noted, references to net income relate to net income attributable to Costco. 23 23 23 Table of Contents Table of Contents Highlights for 2022 versus 2021 include: •We opened 26 new warehouses, including 3 relocations: 14 net new in the U.S., 2 net new in our Canadian segment, and 7 new in our Other International segment, compared to 22 new warehouses, including 2 relocations in 2021; •Net sales increased 16% to $222,730 driven by a 14% increase in comparable sales and sales at new warehouses opened in 2021 and 2022; •Membership fee revenue increased 9% to $4,224, driven by new member sign-ups, upgrades to Executive membership, and an increase in our renewal rate; •Gross margin percentage decreased 65 basis points, driven primarily by our core merchandise categories and a LIFO charge for higher merchandise costs; •SG&A expenses as a percentage of net sales decreased 77 basis points, primarily due to leveraging increased sales and ceasing of incremental wages related to COVID-19, despite additional wage and benefits increases; •We incurred a one-time $77 pretax charge, primarily related to granting our employees one additional day of paid time off in March 2022; •The effective tax rate in 2022 was 24.6% compared to 24.0% in 2021; •Net income increased 17% to $5,844, or $13.14 per diluted share compared to $5,007, or $11.27 per diluted share in 2021; •In June 2022, the Company paid a cash dividend of $208 and purchased the remaining equity interest of its Taiwan operations from its former joint-venture partner for $842, totaling $1,050 in the aggregate; and •In April 2022, the Board of Directors approved an increase in the quarterly cash dividend from $0.79 to $0.90 per share. COVID-19 The COVID-19 pandemic continued to impact our business during 2022, albeit to a lesser extent. COVID-related and other supply and logistics constraints have continued to adversely affect some merchandise categories and are expected to do so for the foreseeable future. During 2021, we paid $515 in incremental wages related to COVID-19, which ceased in February 2021. 24 24 24 Table of Contents Table of Contents

Comparable sales growth is achieved through increasing shopping frequency from new and existing members and the amount they spend on each visit (average ticket).

Highlights for 2023 versus 2022 include: •We opened 26 new warehouses, including three relocations: 13 net new in the U.S. and 10 new in our Other International segment. We opened the same number of new warehouses, including relocations, in 2022; •Net sales increased 7% to $237,710, driven by a 3% increase in comparable sales, sales at new warehouses opened in 2022 and 2023, and the benefit of one additional week of sales in 2023; •Membership fee revenue increased 8% to $4,580, driven by new member sign-ups, upgrades to Executive membership, and one additional week of membership fees in 2023; •Gross margin percentage increased nine basis points, driven primarily by a smaller LIFO charge in 2023 compared to 2022 and our core merchandise categories. This was partially offset by charges of $391, predominantly related to the discontinuation of our charter shipping activities; •SG&A expenses as a percentage of net sales increased 20 basis points, due to increased costs in warehouse operations and other businesses, primarily wage increases effective in March and July 2022, and March 2023, as well as lower sales growth; •The effective tax rate in 2023 was 25.9%, compared to 24.6% in 2022; •Net income increased 8% to $6,292, or $14.16 per diluted share compared to $5,844, or $13.14 per diluted share in 2022; •In January 2023, the Board of Directors authorized a new share repurchase program in the amount of $4,000; and •In April 2023, the Board of Directors approved a 13% increase in the quarterly cash dividend. 22 22 22 Table of Contents Table of Contents

Cash and cash equivalents and short-term investments were $11,049 and $12,175 at the end of 2022 and 2021, respectively. Of these balances, unsettled credit and debit card receivables represented approximately $2,010 and $1,816 at the end of 2022 and 2021. These receivables generally settle within four days. Changes in foreign exchange rates impacted cash and cash equivalents negatively by $249 in 2022, and positively by $46 and $70 in 2021 and 2020. Material contractual obligations arising in the normal course of business primarily consist of purchase obligations, long-term debt and related interest payments, leases, and construction and land purchase obligations. See Notes 4 and 5 to the consolidated financial statements included in Item 8 of this Report for amounts outstanding on August 28, 2022, related to debt and leases. Purchase obligations consist of contracts primarily related to merchandise, equipment, and third-party services, the majority of which are due in the next 12 months. Construction and land purchase obligations consist of contracts primarily related to the development and opening of new and relocated warehouses, the majority of which (other than leases) are due in the next 12 months. Management believes that our cash and investment position and operating cash flows with capacity under existing and available credit agreements will be sufficient to meet our liquidity and capital requirements for the foreseeable future. We believe that our U.S. current and projected asset position is sufficient to meet our U.S. liquidity requirements.

## Modified: Cash Flows from Investing Activities

**Key changes:**

- Reworded sentence: "Net cash used in investing activities totaled $4,972 in 2023, compared to $3,915 in 2022, and is primarily related to capital expenditures."
- Reworded sentence: "In 2023, we spent $4,323 on capital expenditures, and it is our current intention to spend approximately $4,400 to $4,600 during fiscal 2024."
- Reworded sentence: "We opened 26 new warehouses, including three relocations, in 2023, and plan to open up to 28 additional new warehouses, including one relocation, in 2024."

**Prior (2022):**

Net cash used in investing activities totaled $3,915 in 2022, compared to $3,535 in 2021, and is primarily related to capital expenditures. Net cash flows from investing activities also includes purchases and maturities of short-term investments. Capital Expenditures Our primary requirements for capital are acquiring land, buildings, and equipment for new and remodeled warehouses. Capital is also required for information systems, manufacturing and distribution facilities, initial warehouse operations, and working capital. In 2022, we spent $3,891 on capital expenditures, and it is our current intention to spend approximately $3,800 to $4,000 during fiscal 2023. These expenditures are expected to be financed with cash from operations, existing cash and cash equivalents, and short-term investments. We opened 26 new warehouses, including three relocations, in 2022, and plan to open approximately up to 29 additional new warehouses, including four relocations, in 2023. There can be no assurance that current expectations will be realized, and plans are subject to change upon further review of our capital expenditure needs or based on the economic environment.

Such events could result in physical damage to our properties, limitations on store operating hours, less frequent visits by members to physical locations, the temporary closure of warehouses, depots, manufacturing or home office facilities, the temporary lack of an adequate work force, disruptions to our IT systems, the temporary or long-term disruption in the supply of products from some local or overseas suppliers, the temporary disruption in the transport of goods to or from overseas, delays in the delivery of goods to our warehouses or depots, and the temporary reduction in the availability of products in our warehouses. Public health issues, whether occurring in the U.S. or abroad, could disrupt our operations, disrupt the operations of suppliers or members, or have an adverse impact on consumer spending and confidence levels. These events could also reduce demand for our products or make it difficult or impossible to procure products. We may be required to suspend operations in some or all of our locations, which could have a material adverse effect on our business, financial condition and results of operations.

In 2022 and 2021, the Company had valuation allowances of $313 and $214, primarily related to foreign tax credits that the Company believes will not be realized due to carry forward limitations. The foreign tax credit carry forwards are set to expire beginning in fiscal 2030. The Company generally no longer considers fiscal year earnings of non-U.S. consolidated subsidiaries after 2017 to be indefinitely reinvested (other than China and Taiwan) and has recorded the estimated incremental foreign withholding taxes (net of available foreign tax credits) and state income taxes payable assuming a hypothetical repatriation to the U.S. The Company continues to consider undistributed earnings of certain non-U.S. consolidated subsidiaries, which totaled $2,779, to be indefinitely reinvested and has not provided for withholding or state taxes. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits for 2022 and 2021 is as follows: 20222021Gross unrecognized tax benefit at beginning of year$33 $30 Gross increases - current year tax positions1 2 Gross increases - tax positions in prior years12 2 Gross decreases - tax positions in prior years(12) -  Gross decreases - settlements(12) -  Lapse of statute of limitations(6)(1)Gross unrecognized tax benefit at end of year$16 $33 58 58 58 Table of Contents Table of Contents The gross unrecognized tax benefit includes tax positions for which the ultimate deductibility is highly certain but there is uncertainty about the timing of such deductibility. At the end of 2022 and 2021, these amounts were immaterial. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of these tax positions would not affect the annual effective tax rate but would accelerate the payment of cash to the taxing authority. The total amount of such unrecognized tax benefits that if recognized would favorably affect the effective income tax rate in future periods is $15 and $30 at the end of 2022 and 2021. Accrued interest and penalties related to income tax matters are classified as a component of income tax expense. Accrued interest and penalties recognized during 2022 and 2021, and accrued at the end of each respective period were not material. The Company is currently under audit by several jurisdictions in the United States and abroad. Some audits may conclude in the next 12 months, and the unrecognized tax benefits recorded in relation to the audits may differ from actual settlement amounts. It is not practical to estimate the effect, if any, of any amount of such change during the next 12 months to previously recorded uncertain tax positions in connection with the audits. The Company does not anticipate that there will be a material increase or decrease in the total amount of unrecognized tax benefits in the next 12 months. The Company files income tax returns in the United States, various state and local jurisdictions, in Canada, and in several other foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state or local examination for years before fiscal 2018. The Company is currently subject to examination in California for fiscal years 2013 to present. Other Taxes The Company is subject to multiple examinations for value added, sales-based, payroll, product, import or other non-income taxes in various jurisdictions. In certain cases, the Company has received assessments from the authorities. Possible losses or range of possible losses associated with these matters are either immaterial or an estimate of the possible loss or range of loss cannot be made at this time. If certain matters or a group of matters were to be decided adversely to the Company, it could result in a charge that might be material to the results of an individual fiscal quarter or year. 59 59 59 Table of Contents Table of Contents

The Company is principally engaged in the operation of membership warehouses through wholly owned subsidiaries in the U.S., Canada, Mexico, Japan, U.K., Korea, Taiwan, Australia, Spain, France, China, and Iceland. Reportable segments are largely based on management's organization of the operating segments for operational decisions and assessments of financial performance, which considers geographic locations. The material accounting policies of the segments are as described in Note 1. Inter-segment net sales and expenses have been eliminated in computing total revenue and operating income. Effective for fiscal 2022, stock-based compensation was allocated to the segments in this reporting. This change reflected a decision to evaluate the financial performance of the segments inclusive of this expense. Operating income was restated in each of the segments for all prior periods to reflect this change.

Excluding the impact of gasoline price inflation on net sales, gross margin was 10.94%, a decrease of 19 basis points. This was primarily due to a 33 basis-point decrease in core merchandise categories, predominantly driven by decreases in fresh foods and foods and sundries, and 19 basis points due to a LIFO charge for higher merchandise costs. Gross margin was also negatively impacted by one basis point due to increased 2% rewards. Warehouse ancillary and other businesses positively impacted gross margin by 29 basis points, predominantly gasoline, partially offset by e-commerce. Gross margin was positively impacted by five basis points due to the net impact of ceasing incremental wages related to COVID-19 and the negative impact of a one-time charge related to granting our employees one additional day of paid time off. Changes in foreign currencies relative to the U.S. dollar negatively impacted gross margin by approximately $176, compared to 2021, primarily attributable to our Other International Operations. The gross margin in core merchandise categories, when expressed as a percentage of core merchandise sales (rather than total net sales), decreased 27 basis points. The decrease was across all categories, most significantly in fresh foods. This measure eliminates the impact of changes in sales penetration and gross margins from our warehouse ancillary and other businesses. Gross margin on a segment basis, when expressed as a percentage of the segment's own sales and excluding the impact of changes in gasoline prices on net sales (segment gross margin percentage), decreased across all segments. All segments were negatively impacted due to decreases in core merchandise categories, partially offset by increases in warehouse ancillary and other businesses. Gross margin in our U.S. segment was also negatively impacted by the LIFO charge. Our Other International segment was negatively impacted by increased 2% rewards. All segments benefited from the ceasing of incremental wages related to COVID-19. 26 26 26 Table of Contents Table of Contents

Excluding the impact of gasoline price deflation on net sales, gross margin was 10.50%, an increase of two basis points. This two basis point increase was positively impacted by: 18 basis points due to a smaller LIFO charge in 2023 compared to 2022, and seven basis points due to core merchandise categories, predominantly foods and sundries. These were offset by: 16 basis points due to the downsizing and then discontinuation of our charter shipping activities; four basis points due to increased 2% rewards; and three basis points due to warehouse ancillary and other businesses, predominantly e-commerce, partially offset by gasoline and business centers. Changes in foreign currencies relative to the U.S. dollar negatively impacted gross margin by approximately $349, compared to 2022, attributable to our Canadian and Other International Operations. The gross margin in core merchandise categories, when expressed as a percentage of core merchandise sales (rather than total net sales), increased two basis points, driven by foods and sundries and non-foods, partially offset by fresh foods. This measure eliminates the impact of changes in sales penetration and gross margins from our warehouse ancillary and other businesses. Gross margin on a segment basis, when expressed as a percentage of the segment's own sales and excluding the impact of changes in gasoline prices on net sales (segment gross margin percentage), increased in our U.S. segment, due to a smaller LIFO charge and increases in core merchandise categories, primarily foods and sundries, partially offset by the charges related to the discontinuation of our charter shipping activities discussed above and warehouse ancillary and other businesses. Gross margin percentage increased in our Canada segment, attributable to increases in core merchandise categories and warehouse ancillary and other businesses. Our Other International gross margin percentage decreased, largely due to decreases in core merchandise categories, partially offset by warehouse ancillary and other businesses. All segments were negatively impacted by increased 2% rewards.
