NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(amounts in millions, except share, per share, and warehouse count data)

(unaudited)

Note 1—Summary of Significant Accounting Policies

Description of Business

Costco Wholesale Corporation (Costco or the Company), a Washington corporation, and its subsidiaries operate membership warehouses based on the concept that offering members low prices on a limited selection of nationally-branded and private-label products in a wide range of merchandise categories will produce high sales volumes and rapid inventory turnover. At February 18, 2024, Costco operated 874 warehouses worldwide: 602 in the United States (U.S.) located in 47 states, Washington, D.C., and Puerto Rico, 108 in Canada, 40 in Mexico, 33 in Japan, 29 in the United Kingdom (U.K.), 18 in Korea, 15 in Australia,14 in Taiwan, six in China, four in Spain, two in France, and one each in Iceland, New Zealand, and Sweden. The Company operates e-commerce websites in the U.S., Canada, the U.K., Mexico, Korea, Taiwan, Japan, and Australia.

Basis of Presentation

The condensed consolidated financial statements include the accounts of Costco and its wholly-owned subsidiaries. All material inter-company transactions among the Company and its consolidated subsidiaries have been eliminated in consolidation.

These unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q for interim financial reporting pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). While these statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the fiscal year ended September 3, 2023.

Fiscal Year End

The Company operates on a 52/53 week fiscal year basis, with the fiscal year ending on the Sunday closest to August 31. Fiscal 2024 is a 52-week year ending on September 1, 2024. References to the second quarter of 2024 and 2023 relate to the 12-week fiscal quarters ended February 18, 2024, and February 12, 2023. References to the first half of 2024 and 2023 relate to the 24 weeks ended February 18, 2024 and February 12, 2023.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions take into account historical and forward-looking factors that the Company believes are reasonable. Actual results could differ from those estimates and assumptions.

Reclassification

Reclassifications were made to the condensed consolidated statement of cash flows for the first half of fiscal 2023 to conform with current year presentation.

9

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is evaluating the new standard.

In December 2023, the FASB issued ASU 2023-09, which focuses on income tax disclosures by requiring public business entities, on an annual basis, to disclose specific categories in the rate reconciliation, provide information for reconciling items that meet a quantitative threshold, and certain information about income taxes paid. The standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The amendments should be applied on a prospective basis. Retrospective application is permitted. The Company is evaluating the new standard.

Note 2—Investments

The Company's investments were as follows:

February 18, 2024:	Cost Basis		Unrealized Losses, Net		Recorded Basis

Note 3—Fair Value Measurement

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The table below presents information regarding the Company’s financial assets and financial liabilities that are measured at fair value on a recurring basis and indicates the level within the hierarchy reflecting the valuation techniques utilized.

	Level 2
	February 18, 2024		September 3, 2023
Investment in government and agency securities(1)	$	669	$	633
Forward foreign-exchange contracts, in asset position(2)	12		18
Forward foreign-exchange contracts, in (liability) position(2)	(4)		(7)
Total	$	677	$	644

 _______________

(1)At February 18, 2024, $4 cash and cash equivalents and $665 short-term investments are included in the accompanying condensed consolidated balance sheets.

(2)The asset and liability values are included in other current assets and other current liabilities, respectively, in the accompanying condensed consolidated balance sheets.

At February 18, 2024, and September 3, 2023, the Company did not hold any Level 1 or 3 financial assets or liabilities that were measured at fair value on a recurring basis. There were no transfers between levels during the first half of 2024 or 2023.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Assets and liabilities recognized and disclosed at fair value on a nonrecurring basis include items such as financial assets measured at amortized cost and long-lived nonfinancial assets. These assets are measured at fair value if determined to be impaired. There were no material fair value adjustments to these items during the first half of 2024. During the first quarter of 2023, the Company recognized in merchandise costs a charge of $93, primarily related to the impairment of certain leased assets associated with charter shipping activities, now discontinued.

Note 4—Debt

The carrying value of the Company’s long-term debt consisted of the following:

	February 18, 2024		September 3, 2023
2.750% Senior Notes due May 2024	$	1,000	$	1,000
3.000% Senior Notes due May 2027	1,000		1,000
1.375% Senior Notes due June 2027	1,250		1,250

Total long-term debt	6,969		6,484
Less unamortized debt discounts and issuance costs	24		26

Long-term debt, excluding current portion	$	5,865	$	5,377

 _______________

(1)Net of unamortized debt discounts and issuance costs.

The fair value of the Senior Notes is estimated using Level 2 inputs. Other long-term debt consists of Guaranteed Senior Notes issued by the Company's Japan subsidiary, valued using Level 3 inputs. In November 2023, the Company's Japan subsidiary issued four Guaranteed Senior Notes, totaling approximately $500, at fixed interest rates ranging from 1.400% to 2.120%. Interest is payable semi-annually, and maturity dates range from November 7, 2033, to November 7, 2043. The fair value of the Company's long-term debt, including the current portion, was approximately $6,306 and $5,738 at February 18, 2024, and September 3, 2023.

Note 6—Stock-Based Compensation

The 2019 Incentive Plan authorized the issuance of up to a maximum of 15,885,000 RSUs. To preserve the value of outstanding awards, the number of RSUs that may be granted under this Plan is subject to adjustments from changes in capital structure. The Company issues new shares of common stock upon vesting of RSUs. Shares for vested RSUs are generally delivered to participants annually, net of shares withheld for taxes.

As required by the 2019 Incentive Plan, in conjunction with the 2024 special cash dividend, the number of shares subject to outstanding RSUs was increased on the dividend record date to preserve their value. They were adjusted by multiplying the number of outstanding shares by a factor of 1.018, representing the ratio of the Nasdaq closing price of $674.62 on December 26, 2023, which was the last trading day immediately prior to the ex-dividend date, to the Nasdaq opening price of $662.70 on the ex-dividend date, December 27, 2023. The outstanding RSUs increased by approximately 52,000. The adjustment did not result in additional stock-based compensation expense, as the fair value of the awards did not change. As further required by the 2019 Incentive Plan, the maximum number of shares issuable under the plan was proportionally adjusted, which resulted in an additional 128,000 RSU shares available to be granted.

Summary of Restricted Stock Unit Activity

At February 18, 2024, 7,249,000 shares were available to be granted as RSUs, and the following awards, adjusted for the effects of the special dividend, were outstanding:

•2,749,000 time-based RSUs, which vest upon continued employment over specified periods and accelerate upon achievement of a long-service term;

•70,000 performance-based RSUs granted to executive officers of the Company, for which the performance targets have been met. The awards vest upon continued employment over specified periods of time and upon achievement of a long-service term; and

•91,000 performance-based RSUs granted to executive officers of the Company, subject to achievement of performance targets for 2024, as determined by the Compensation Committee of the Board of Directors after the end of the fiscal year. These awards are included in the table below. The Company recognized compensation expense for these awards in the second quarter of 2024, as it is currently deemed probable that the targets will be achieved.

The following table summarizes RSU transactions during the first half of 2024:

	Number of Units (in 000s)	Weighted-Average Grant Date Fair Value

Note 7—Net Income per Common and Common Equivalent Share

The following table shows the amounts used in computing net income per share and the weighted average number of shares of basic and of potentially dilutive common shares outstanding (shares in 000s):

	12 Weeks Ended				24 Weeks Ended
	February 18, 2024		February 12, 2023		February 18, 2024		February 12, 2023
Net income	$	1,743	$	1,466	$	3,332	$	2,830
Weighted average basic shares	443,892		443,877		443,859		443,857
RSUs	862		598		720		646
Weighted average diluted shares	444,754		444,475		444,579		444,503
Anti-dilutive RSUs	—		6		—		—

Anti-dilutive shares are excluded from the calculation of diluted shares and earnings per diluted share because their impact would increase earnings per diluted shares.

Basic earnings per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated based on the dilutive effect of RSUs using the treasury stock method.

Note 8—Commitments and Contingencies

Legal Proceedings

The Company is involved in many claims, proceedings and litigations arising from its business and property ownership. In accordance with applicable accounting guidance, the Company establishes an accrual for legal proceedings if and when those matters present loss contingencies that are both probable and reasonably estimable. There may be losses in excess of amounts accrued. The Company monitors those matters for developments that would affect the likelihood of a loss (taking into account where applicable indemnification arrangements concerning suppliers and insurers) and the accrued amount, if any, thereof, and adjusts the amount as appropriate. The Company has recorded immaterial accruals with respect to certain matters described below, in addition to other immaterial accruals for matters not described below. If the loss contingency at issue is not both probable and reasonably estimable, the Company does not establish an accrual, but monitors for developments that make the contingency both probable and reasonably estimable. In each case, there is a reasonable possibility that a loss may be incurred, including a loss in excess of the applicable accrual. For matters where no accrual has been recorded, the possible loss or range of loss (including any loss in excess of the accrual) cannot, in the Company's view, be reasonably estimated because, among other things: the remedies or penalties sought are indeterminate or unspecified; the legal and/or factual theories are not well developed; and/or the matters involve complex or novel legal theories or a large number of parties.

In November 2023, a former employee filed a class action against the Company alleging claims under California law for failure to pay minimum wage, failure to pay overtime, failure to provide meal and rest breaks, failure to provide accurate wage statements, failure to reimburse expenses, failure to pay wages when due, and failure to pay sick pay. Martin Reyes v. Costco Wholesale Corporation, Sacramento County Superior Court. (Case No. 23cv011351). An amended complaint has been filed, as to which the Company has yet to respond.

In October 2023, current and former employees filed suit against the Company asserting collective and class claims on behalf of all “Junior Managers” under the Fair Labor Standards Act and New York Labor Law, for failure to pay overtime compensation and for inaccurate wage statements under New York law.

Lock et al. v. Costco Wholesale Corp. (Case No. 2:23-cv-07904; E.D.N.Y.). On February 1, 2024, the Company served a motion to dismiss the inaccurate wage-statement claim.

In October 2023, a current employee filed suit against the Company asserting collective and class claims on behalf of all “supervisors” employed in New Jersey, under the Fair Labor Standards Act and New Jersey Wage and Hour Law for failure to pay all hours worked. Shah v. Costco Wholesale Corp. (Case No. 2:23-cv-21286; D.N.J.). On December 26, 2023, the Company filed its answer, denying all claims.

In July 2021, a former temporary staffing employee filed a class action against the Company and a staffing company, alleging violations of the California Labor Code regarding payment of wages, meal and rest periods, wage statements, the timeliness of wages and final wages, and for unfair business practices. Dimas v. Costco Wholesale Corp. (Case No. STK-CV-UOE-2021-0006024; San Joaquin Superior Court). The Company has moved to compel arbitration of the plaintiff's individual claims and to dismiss the class action complaint. On September 7, 2021, the same plaintiff filed a separate representative action under the California Private Attorneys General Act, asserting the same Labor Code violations and seeking civil penalties and attorneys' fees. The case has been stayed pending arbitration of the plaintiff's individual claims.

In May 2022, an employee filed an action under the California Private Attorneys General Act against the Company, alleging claims under the California Labor Code regarding the payment of wages, meal and rest periods, the timeliness of wages and final wages, wage statements, accurate records and business expenses. Gonzalez v. Costco Wholesale Corp. (Case No. 22AHCV00255; Los Angeles Superior Court). The Company filed an answer denying the allegations. On October 31, 2023, a settlement was reached for an immaterial amount. A hearing on preliminary approval of the settlement is scheduled for April 23, 2024.

Beginning in December 2017, the United States Judicial Panel on Multidistrict Litigation consolidated numerous cases concerning the impacts of opioid abuses filed against various defendants by counties, cities, hospitals, Native American tribes, third-party payors, and others. In re National Prescription Opiate Litigation (MDL No. 2804) (N.D. Ohio). Included are cases filed against the Company by counties and cities in Michigan, New Jersey, Oregon, Virginia and South Carolina, a third-party payor in Ohio, and a hospital in Texas, class actions filed on behalf of infants born with opioid-related medical conditions in 40 states, and class actions and individual actions filed on behalf of individuals seeking to recover alleged increased insurance costs associated with opioid abuse in 43 states and American Samoa. Claims against the Company filed in federal court outside the MDL have been asserted by certain counties and cities in Florida and Georgia; claims filed by certain cities and counties in New York are pending in state court. Claims against the Company in state courts in New Jersey, Oklahoma, Utah, and Arizona have been dismissed. The Company is defending all of the pending matters.

Members of the Board of Directors, six corporate officers and the Company were defendants in a shareholder derivative action filed in June 2022 related to chicken welfare and alleged breaches of fiduciary duties. Smith, et ano. v. Vachris, et al., Superior Court of the State of Washington, County of King, No, 22-2-08937-7SEA. The complaint sought from the individual defendants' damages, injunctive relief, costs, and attorneys' fees. On March 28, 2023, the court granted the defendants' motion to dismiss the action. The plaintiffs subsequently made a demand that the Board of Directors take various actions, including among other things, pursuing claims against directors and officers of the type asserted in the litigation. A demand review committee of the Board has been appointed to make a recommendation to the Board as to the demand.

In February 2023, Go Green Norcal, LLC filed an arbitration demand against the Company. The demand alleged a breach of a supply agreement and sought unspecified damages and cancellation of a loan from the Company. In March 2023, the Company filed its answer, denying any breach by the Company, along with counterclaims against Go Green and an affiliate for breach of contract, negligent misrepresentation, and an accounting. In August 2023 the plaintiff asserted that its damages exceed $70 million. An award to the plaintiffs of an immaterial amount was paid in February 2024.

Between September 25, 2023, and October 31, 2023, five class action suits were filed against the Company alleging various privacy law violations stemming from pixel trackers on Costco.com. Birdwell v. Costco Wholesale Corp., Case No. T23-1405, Contra Costa County Superior Court; and Scott v. Costco Wholesale Corp., Case No. 2:23-cv-08808 (C.D. Cal.), now consolidated with R.S. v. Costco Wholesale Corp., Case No. 2:23-cv-01628 (W.D. Wash.); Groves, et ano. v. Costco Wholesale Corp., Case No. 2:23-cv-01662 (W.D. Wash.) and Castillo v. Costco Wholesale Corp., under Case No. 2:34-cv-01548 (W.D. Wash.). The Castillo plaintiffs filed a consolidated complaint on January 26, 2024, which seeks damages, equitable relief and attorneys’ fees under various statutes, including the Washington Consumer Protection Act, Washington Privacy Act, Washington Uniform Health Care Information Act, Electronic Communications Privacy Act, California Invasion of Privacy Act, and California Confidentiality of Medical Information Act. The consolidated complaint also alleges breach of implied contract, invasion of privacy, conversion and unjust enrichment. The Company filed a motion to dismiss and demurrer in Birdwell and has not responded to the Castillo consolidated complaint. On January 2, 2024, the Company received a related civil investigative demand from the Washington Attorney General's office. On January 3, 2024, the Company received a related pre-litigation letter from the Los Angeles Office of the County Counsel.

In October 2021 the Company received a notice that the Quebec Health Insurance Board had commenced an inquiry to determine whether the Company had given or received improper payments for drugs that are covered by the province's prescription drug program from drug wholesalers, generic drug manufacturers or the independent pharmacist who owns and operates the pharmacies located in the Company's Quebec locations. The inquiry covers a period beginning January 1, 2017.

In January 2023 the Company received a Civil Investigative Demand from the U.S. Attorney's Office, Western District of Washington, requesting documents. The government is conducting a False Claims Act investigation concerning whether the Company presented or caused to be presented to the federal government for payment false claims relating to prescription medications.

The Company does not believe that any pending claim, proceeding or litigation, either alone or in the aggregate, will have a material adverse effect on the Company’s financial position, results of operations or cash flows; it is possible that an unfavorable outcome of some or all of the matters, however unlikely, could result in a charge that might be material to the results of an individual fiscal quarter or year.

OVERVIEW

Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to promote understanding of the results of operations and financial condition. MD&A is provided as a supplement to, and should be read in conjunction with, our condensed consolidated financial statements and the accompanying Notes to Financial Statements (Part I, Item 1 of this Form 10-Q), as well as our consolidated financial statements, the accompanying Notes to Financial Statements, and the related Management's Discussion and Analysis of Financial Condition and Results of Operations in our fiscal year 2023 Form 10-K, filed with the United States Securities and Exchange Commission on October 11, 2023.

We operate membership warehouses and e-commerce websites based on the concept that offering members low prices on a limited selection of nationally-branded and private-label products in a wide range of categories will produce high sales volumes and rapid inventory turnover. When combined with the operating efficiencies achieved by volume purchasing, efficient distribution and reduced handling of merchandise in no-frills, self-service warehouse facilities, these volumes and turnover enable us to operate profitably at significantly lower gross margins (net sales less merchandise costs) than most other retailers. We often sell inventory before we are required to pay for it, even while taking advantage of early payment discounts.

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). Comparable sales is

18

defined 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. The measure is intended as supplemental information and is not a substitute for net sales presented in accordance with U.S. GAAP. 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); and inflation or deflation 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 selling general and administrative (SG&A) expenses, reducing them as a percentage of sales and enhancing profitability. Generating comparable sales growth is foremost a question of making available 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. 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; it generally has a lower gross margin percentage and lower SG&A expense relative to our non-gasoline businesses. A higher penetration of gasoline sales will generally lower our gross margin percentage. 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.

Government actions in various countries relating to tariffs, 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. Negative aspects of such growth include lower initial operating profitability relative to existing warehouses and cannibalization of sales at existing warehouses when openings occur in existing markets. 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, domestically and internationally, generally has a lower gross-margin percentage than our warehouse operations.

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 Executive memberships, 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.

19

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 9 to the consolidated financial statements included in Part I, Item 1, 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 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 and prior period's exchange rates. The impact of changes in gasoline prices on net sales is calculated based on the difference between the current and prior period's average price per gallon sold. Results expressed excluding the impacts of foreign exchange and gasoline prices are intended as supplemental information and are not a substitute for net sales presented in accordance with U.S. GAAP and should be reviewed in conjunction with results reported in accordance with U.S. GAAP.

Our fiscal year ends on the Sunday closest to August 31. References to the second quarter of 2024 and 2023 relate to the 12-week fiscal quarters ended February 18, 2024, and February 12, 2023. References to the first half of 2024 and 2023 relate to the 24 weeks ended February 18, 2024, and February 12, 2023. Certain percentages presented are calculated using actual results prior to rounding.

Highlights for the second quarter of 2024 versus 2023 include:

•Net sales increased 6% to $57,331, driven by an increase in comparable sales and sales at 26 net new warehouses opened since the end of the second quarter of 2023;

•Membership fee revenue increased 8% to $1,111, driven by new member sign-ups, upgrades to Executive Membership, and a higher renewal rate;

•Gross margin percentage increased eight basis points, driven primarily by our warehouse ancillary and other businesses and core merchandise categories, partially offset by an increase in 2% rewards;

•SG&A expenses as a percentage of net sales increased three basis points, primarily due to increased costs in warehouse operations and other businesses, including the impact of wage increases in March and September 2023, partially offset by central operating costs;

•A quarterly cash dividend of $1.02 per share was declared on January 18, 2024, and paid on February 16, 2024. On January 12, 2024, an aggregate payment of approximately $6,655 was made in connection with a special cash dividend of $15.00 per share, declared on December 13, 2023;

•Our effective tax rate was 22.1% and was positively impacted by a $94 benefit, or $0.21 per diluted share, related to the special cash dividend; and

•Net income was $1,743, $3.92 per diluted share, compared to $1,466, $3.30 per diluted share in 2023.

(1)Comparable sales for the second quarter and first half of 2024 were calculated using comparable retail weeks.

Net Sales

Net sales increased $3,092 or 6%, and $6,372 or 6% during the second quarter and first half of 2024. The improvement was attributable to an increase in comparable sales of 6% and 5% in the second quarter and first half of 2024, and sales at the 26 net new warehouses opened since the end of the second quarter of 2023. Sales increased $2,645, or 6% and $5,566, or 6% in core merchandise categories during the second quarter and first half of 2024, due to increases in all categories. Sales in warehouse ancillary and other businesses increased $447 or 4%, and $806, or 4% during the second quarter and first half of 2024, led by pharmacy.

During the second quarter of 2024, lower gasoline prices negatively impacted net sales by $231, 43 basis points, compared to 2023, with a 3% decrease in the average price per gallon. Changes in foreign currencies relative to the U.S. dollar positively impacted net sales by approximately $94, 17 basis points, compared to the second quarter of 2023, attributable to our Canadian and Other International operations.

During the first half of 2024, lower gasoline prices negatively impacted net sales by $572, 53 basis points, compared to 2023, with a 4% decrease in the average price per gallon. Changes in foreign currencies relative to the U.S. dollar positively impacted net sales by approximately $289, 27 basis points, compared to the second quarter of 2023, attributable to our Other International operations, partially offset by our Canadian operations.

21

Comparable Sales

Comparable sales increased 6% and 5% in the second quarter and first half of 2024 and were positively impacted by increased shopping frequency and a slightly higher average ticket.

Membership fee revenue increased 8% in both the second quarter and first half of 2024, driven by new member sign-ups, upgrades to Executive Membership, and a higher renewal rate. At the end of the second quarter of 2024, our renewal rates were 92.9% in the U.S. and Canada and 90.5% worldwide. Renewal rates benefited from higher penetration of Executive members. Our renewal rate, which excludes affiliates of Business members, is a trailing calculation that captures renewals during the period seven to eighteen months prior to the reporting date.

We account for membership fee revenue on a deferred basis, recognized ratably over the one-year membership period.

Gross margin percentage	10.80		%	10.72		%	10.92		%	10.67		%

Quarterly Results

Gross margin percentage increased eight basis points. Excluding the impact of gasoline price deflation on net sales, gross margin percentage was 10.76%, an increase of four basis points. The four basis-point increase was positively impacted by: six basis points due to warehouse ancillary and other businesses, primarily e-commerce; three basis points due to a LIFO benefit; and two basis points due to core merchandise categories. This increase was partially offset by seven basis points due to increased 2% rewards.

The gross margin in core merchandise categories, when expressed as a percentage of core merchandise sales (rather than total net sales), increased 25 basis points. The increase was primarily due to non-foods and foods and sundries, partially offset by fresh foods. This measure eliminates the impact of changes in sales penetration and gross margin from our warehouse ancillary and other businesses.

Gross margin percentage 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 in our U.S. segment due to core merchandise categories and increased 2% rewards, partially offset by warehouse ancillary and other businesses and a LIFO benefit. Gross margin increased in our Canadian segment, largely due to core merchandise categories. Gross margin decreased in our Other International segment, primarily due to increased 2% rewards and warehouse ancillary and other businesses, partially offset by increases in core merchandise categories.

22

Year-to-date Results

Gross margin percentage increased 25 basis points. Excluding the impact of gasoline price deflation on net sales, gross margin percentage was 10.86%, an increase of 19 basis points. The 19 basis-point increase was positively impacted by: 15 basis points due to warehouse ancillary and other business, primarily e-commerce; nine basis points due to the absence of a charge related to the discontinuation of our charter shipping activities that was recorded in the first quarter of 2023; and two basis points due to a LIFO benefit. This increase was partially offset by five basis points due to increased 2% rewards and two basis points due to core merchandise categories.

The gross margin in core merchandise categories, when expressed as a percentage of core merchandise sales (rather than total net sales), increased 14 basis points. The increase was primarily due to non-foods, partially offset by fresh foods.

Segment gross margin percentage increased in our U.S. and Canadian segments. Our U.S. segment performed similarly to the consolidated results above. Our Canadian segment gross margin increased at a greater rate compared to our consolidated results, primarily due to increases in core merchandise categories, partially offset by increased 2% rewards. Gross margin percentage was flat in our Other International segment, positively impacted by core merchandise categories, offset by increased 2% rewards.

Quarterly Results

SG&A expenses as a percentage of net sales increased three basis points. SG&A expenses as a percentage of net sales excluding the impact of gasoline price deflation was 9.10%, a decrease of one basis point. The comparison to last year was favorably impacted by five basis points due to central operating costs and four basis points due to lower stock compensation expense. Warehouse operations and other businesses were higher by eight basis points, driven by our U.S. operations, which included the impact of wage increases in March and September 2023. SG&A expenses as a percentage of net sales were lower in our Canadian and Other International operations.

Year-to-date Results

SG&A expenses as a percentage of net sales increased 14 basis points. SG&A expenses as a percentage of net sales excluding the impact of gasoline price deflation was 9.25%, an increase of 10 basis points. The comparison to last year was negatively impacted by 11 basis points in warehouse operations and other businesses, driven by our U.S. operations, which included the impact of wage increases in March and September 2023. Preopening costs were also higher by one basis point. SG&A was positively impacted by two basis points due to central operating costs. SG&A expenses as a percentage of net sales were lower in our Canadian and Other International operations.

The increase in interest income in the second quarter and first half of 2024 was due to higher global interest rates and higher average cash and investment balances, prior to the payment of the special cash dividend. Foreign-currency transaction gains (losses), net, include revaluation or settlement of monetary assets and liabilities by our Canadian and Other International operations and mark-to-market adjustments for forward foreign-exchange contracts. See Derivatives and Foreign Currency sections in Item 8, Note 1 of our Annual Report on Form 10-K, for the fiscal year ended September 3, 2023.

This included $94 related to the portion of the special cash dividend payable through our 401(k) plan in the second quarter and $44 of excess tax benefits related to stock compensation in the first quarter. Excluding discrete net tax benefits, the tax rate was 26.5%.

The effective tax rate for the first half of 2023 was impacted by net discrete tax benefits of $57, primarily due to excess tax benefits related to stock compensation in the first quarter. Excluding discrete net tax benefits, the tax rate was 26.1%.

LIQUIDITY AND CAPITAL RESOURCES

The following table summarizes our significant sources and uses of cash and cash equivalents:

	24 Weeks Ended
	February 18, 2024		February 12, 2023
Net cash provided by operating activities	$	5,382	$	5,802
Net cash used in investing activities	(1,752)		(1,865)
Net cash used in financing activities	(8,250)		(1,215)

Our primary sources of liquidity are cash flows from operations, cash and cash equivalents, and short-term investments. Cash and cash equivalents and short-term investments were $10,321 and $15,234 at February 18, 2024, and September 3, 2023. Of these balances, unsettled credit and debit card receivables represented approximately $2,069 and $2,282 at February 18, 2024, and September 3, 2023. These receivables generally settle within four days.

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.

24

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.

Cash Flows from Operating Activities

Net cash provided by operating activities totaled $5,382 in the first half of 2024, compared to $5,802 in the first half of 2023. Our cash flow provided by operations is primarily from net sales and membership fees. Cash flow used in operations generally consists of payments to merchandise suppliers, warehouse operating costs, including payroll and employee benefits, utilities, and credit and debit card processing fees. Cash used in operations also includes payments for income taxes. Changes in our net investment in merchandise inventories (the difference between merchandise inventories and accounts payable) is impacted by several factors, including inventory levels and turnover, the forward deployment of inventory to accelerate delivery times, payment terms with suppliers, and early payments to obtain discounts.

Cash Flows from Investing Activities

Net cash used in investing activities totaled $1,752 in the first half of 2024, compared to $1,865 in the first half of 2023, and is primarily related to capital expenditures. Net cash from investing activities also includes purchases and maturities of short-term investments.

Capital Expenditure Plans

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 the first half of 2024, we spent $2,071 on capital expenditures, and it is our current intention to spend a total of approximately $4,400 to $4,600 during fiscal 2024. These expenditures are expected to be financed with cash from operations, existing cash and cash equivalents, and short-term investments. We opened 14 new warehouses, including one relocation, in the first half of 2024 and plan to open 16 additional new warehouses, including one relocation, in the remainder of fiscal 2024. 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 and the economic environment.

Cash Flows from Financing Activities

Net cash used in financing activities totaled $8,250 in the first half of 2024, compared to $1,215 in the first half of 2023. Cash flow used in financing activities during the first half of 2024 was primarily related to the payment of dividends, repayments of short-term borrowings, and repurchases of common stock. In November 2023, the Company's Japan subsidiary issued four Guaranteed Senior Notes totaling approximately $500 at fixed interest rates ranging from 1.400% to 2.120%.

Dividends

A quarterly cash dividend of $1.02 per share was declared on January 18, 2024, payable to shareholders of record on February 2, 2024, which was paid on February 16, 2024. On January 12, 2024, an aggregate payment of approximately $6,655 was made in connection with a special cash dividend of $15.00 per share, declared on December 13, 2023.

25

Share Repurchase Program

On January 19, 2023, the Board of Directors authorized a share repurchase program in the amount of $4,000, which expires in January 2027. During the first half of 2024 and 2023, we repurchased 528,000 and 579,000 shares of common stock, at an average price per share of $609.51 and $492.06, totaling approximately $322 and $285. These amounts may differ from the accompanying condensed consolidated statements of cash flows due to changes in unsettled repurchases at the end of a quarter. Purchases are made from time to time, as conditions warrant, in the open market or in block purchases, pursuant to plans under SEC Rule 10b5-1. Repurchased shares are retired, in accordance with the Washington Business Corporation Act. The remaining amount available to be purchased under our approved plan was $3,241 at the end of the second quarter.

Bank Credit Facilities and Commercial Paper Programs

We maintain bank credit facilities for working capital and general corporate purposes. At February 18, 2024, we had borrowing capacity under these facilities of $1,237. Our international operations maintain $748 of this capacity under bank credit facilities, of which $164 is guaranteed by the Company. Short-term borrowings outstanding under the bank credit facilities, which are included in other current liabilities on the consolidated balance sheets, were immaterial at the end of the second quarter of 2024 and at the end of fiscal 2023.

The Company has letter of credit facilities, for commercial and standby letters of credit, totaling $210. The outstanding commitments under these facilities at the end of the second quarter of 2024 totaled $184, most of which were standby letters of credit that do not expire or have expiration dates within one year. The bank credit facilities have various expiration dates, most within one year, and we generally intend to renew these facilities. The amount of borrowings available at any time under our bank credit facilities is reduced by the amount of standby and commercial letters of credit outstanding.

Critical Accounting Estimates

The preparation of our consolidated financial statements in accordance with U.S. GAAP requires that we make estimates and judgments. We base these on historical experience and on assumptions that we believe to be reasonable. Our critical accounting policies are discussed in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our Annual Report on Form 10-K, for the fiscal year ended September 3, 2023. There have been no material changes to the critical accounting estimates previously disclosed in that Report.

Item 4—Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended) are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and to ensure that information required to be disclosed is accumulated and communicated to management, including our principal executive and financial officers, to allow timely decisions regarding disclosure. The Chief Executive Officer and the Chief Financial Officer, with assistance from other members of management, have reviewed the effectiveness of our disclosure controls and procedures as of February 18, 2024, and, based on their evaluation, have concluded the disclosure controls and procedures were effective as of such date.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) of the Exchange Act) that occurred during the second quarter of fiscal 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Accounting Policies [Abstract]

Summary of Significant Policies

Note 1—Summary of Significant Accounting Policies

Description of Business

Costco Wholesale Corporation (Costco or the Company), a Washington corporation, and its subsidiaries operate membership warehouses based on the concept that offering members low prices on a limited selection of nationally-branded and private-label products in a wide range of merchandise categories will produce high sales volumes and rapid inventory turnover. At February 18, 2024, Costco operated 874 warehouses worldwide: 602 in the United States (U.S.) located in 47 states, Washington, D.C., and Puerto Rico, 108 in Canada, 40 in Mexico, 33 in Japan, 29 in the United Kingdom (U.K.), 18 in Korea, 15 in Australia,14 in Taiwan, six in China, four in Spain, two in France, and one each in Iceland, New Zealand, and Sweden. The Company operates e-commerce websites in the U.S., Canada, the U.K., Mexico, Korea, Taiwan, Japan, and Australia.

Basis of Presentation

The condensed consolidated financial statements include the accounts of Costco and its wholly-owned subsidiaries. All material inter-company transactions among the Company and its consolidated subsidiaries have been eliminated in consolidation.

These unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q for interim financial reporting pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). While these statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the fiscal year ended September 3, 2023.

Fiscal Year End

The Company operates on a 52/53 week fiscal year basis, with the fiscal year ending on the Sunday closest to August 31. Fiscal 2024 is a 52-week year ending on September 1, 2024. References to the second quarter of 2024 and 2023 relate to the 12-week fiscal quarters ended February 18, 2024, and February 12, 2023. References to the first half of 2024 and 2023 relate to the 24 weeks ended February 18, 2024 and February 12, 2023.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions take into account historical and forward-looking factors that the Company believes are reasonable. Actual results could differ from those estimates and assumptions.

Reclassification

Reclassifications were made to the condensed consolidated statement of cash flows for the first half of fiscal 2023 to conform with current year presentation.

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is evaluating the new standard.

In December 2023, the FASB issued ASU 2023-09, which focuses on income tax disclosures by requiring public business entities, on an annual basis, to disclose specific categories in the rate reconciliation, provide information for reconciling items that meet a quantitative threshold, and certain information about income taxes paid. The standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The amendments should be applied on a prospective basis. Retrospective application is permitted. The Company is evaluating the new standard.

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation Plans

Note 6—Stock-Based Compensation

The 2019 Incentive Plan authorized the issuance of up to a maximum of 15,885,000 RSUs. To preserve the value of outstanding awards, the number of RSUs that may be granted under this Plan is subject to adjustments from changes in capital structure. The Company issues new shares of common stock upon vesting of RSUs. Shares for vested RSUs are generally delivered to participants annually, net of shares withheld for taxes.

As required by the 2019 Incentive Plan, in conjunction with the 2024 special cash dividend, the number of shares subject to outstanding RSUs was increased on the dividend record date to preserve their value. They were adjusted by multiplying the number of outstanding shares by a factor of 1.018, representing the ratio of the Nasdaq closing price of $674.62 on December 26, 2023, which was the last trading day immediately prior to the ex-dividend date, to the Nasdaq opening price of $662.70 on the ex-dividend date, December 27, 2023. The outstanding RSUs increased by approximately 52,000. The adjustment did not result in additional stock-based compensation expense, as the fair value of the awards did not change. As further required by the 2019 Incentive Plan, the maximum number of shares issuable under the plan was proportionally adjusted, which resulted in an additional 128,000 RSU shares available to be granted.

Summary of Restricted Stock Unit Activity

At February 18, 2024, 7,249,000 shares were available to be granted as RSUs, and the following awards, adjusted for the effects of the special dividend, were outstanding:

•2,749,000 time-based RSUs, which vest upon continued employment over specified periods and accelerate upon achievement of a long-service term;

•70,000 performance-based RSUs granted to executive officers of the Company, for which the performance targets have been met. The awards vest upon continued employment over specified periods of time and upon achievement of a long-service term; and

•91,000 performance-based RSUs granted to executive officers of the Company, subject to achievement of performance targets for 2024, as determined by the Compensation Committee of the Board of Directors after the end of the fiscal year. These awards are included in the table below. The Company recognized compensation expense for these awards in the second quarter of 2024, as it is currently deemed probable that the targets will be achieved.

The following table summarizes RSU transactions during the first half of 2024:

	Number of Units (in 000s)	Weighted-Average Grant Date Fair Value
Outstanding at September 3, 2023	3,045	$	405.63

The remaining unrecognized compensation cost related to RSUs unvested at February 18, 2024, was $1,098, and the weighted-average period over which this cost will be recognized is 1.8 years.

Anti-dilutive RSUs	—		6		—		—

Anti-dilutive shares are excluded from the calculation of diluted shares and earnings per diluted share because their impact would increase earnings per diluted shares.

Basic earnings per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated based on the dilutive effect of RSUs using the treasury stock method.

Note 8—Commitments and Contingencies

Legal Proceedings

The Company is involved in many claims, proceedings and litigations arising from its business and property ownership. In accordance with applicable accounting guidance, the Company establishes an accrual for legal proceedings if and when those matters present loss contingencies that are both probable and reasonably estimable. There may be losses in excess of amounts accrued. The Company monitors those matters for developments that would affect the likelihood of a loss (taking into account where applicable indemnification arrangements concerning suppliers and insurers) and the accrued amount, if any, thereof, and adjusts the amount as appropriate. The Company has recorded immaterial accruals with respect to certain matters described below, in addition to other immaterial accruals for matters not described below. If the loss contingency at issue is not both probable and reasonably estimable, the Company does not establish an accrual, but monitors for developments that make the contingency both probable and reasonably estimable. In each case, there is a reasonable possibility that a loss may be incurred, including a loss in excess of the applicable accrual. For matters where no accrual has been recorded, the possible loss or range of loss (including any loss in excess of the accrual) cannot, in the Company's view, be reasonably estimated because, among other things: the remedies or penalties sought are indeterminate or unspecified; the legal and/or factual theories are not well developed; and/or the matters involve complex or novel legal theories or a large number of parties.

In November 2023, a former employee filed a class action against the Company alleging claims under California law for failure to pay minimum wage, failure to pay overtime, failure to provide meal and rest breaks, failure to provide accurate wage statements, failure to reimburse expenses, failure to pay wages when due, and failure to pay sick pay. Martin Reyes v. Costco Wholesale Corporation, Sacramento County Superior Court. (Case No. 23cv011351). An amended complaint has been filed, as to which the Company has yet to respond.

In October 2023, current and former employees filed suit against the Company asserting collective and class claims on behalf of all “Junior Managers” under the Fair Labor Standards Act and New York Labor Law, for failure to pay overtime compensation and for inaccurate wage statements under New York law.

Lock et al. v. Costco Wholesale Corp. (Case No. 2:23-cv-07904; E.D.N.Y.). On February 1, 2024, the Company served a motion to dismiss the inaccurate wage-statement claim.

In October 2023, a current employee filed suit against the Company asserting collective and class claims on behalf of all “supervisors” employed in New Jersey, under the Fair Labor Standards Act and New Jersey Wage and Hour Law for failure to pay all hours worked. Shah v. Costco Wholesale Corp. (Case No. 2:23-cv-21286; D.N.J.). On December 26, 2023, the Company filed its answer, denying all claims.

In July 2021, a former temporary staffing employee filed a class action against the Company and a staffing company, alleging violations of the California Labor Code regarding payment of wages, meal and rest periods, wage statements, the timeliness of wages and final wages, and for unfair business practices. Dimas v. Costco Wholesale Corp. (Case No. STK-CV-UOE-2021-0006024; San Joaquin Superior Court). The Company has moved to compel arbitration of the plaintiff's individual claims and to dismiss the class action complaint. On September 7, 2021, the same plaintiff filed a separate representative action under the California Private Attorneys General Act, asserting the same Labor Code violations and seeking civil penalties and attorneys' fees. The case has been stayed pending arbitration of the plaintiff's individual claims.

In May 2022, an employee filed an action under the California Private Attorneys General Act against the Company, alleging claims under the California Labor Code regarding the payment of wages, meal and rest periods, the timeliness of wages and final wages, wage statements, accurate records and business expenses. Gonzalez v. Costco Wholesale Corp. (Case No. 22AHCV00255; Los Angeles Superior Court). The Company filed an answer denying the allegations. On October 31, 2023, a settlement was reached for an immaterial amount. A hearing on preliminary approval of the settlement is scheduled for April 23, 2024.

Beginning in December 2017, the United States Judicial Panel on Multidistrict Litigation consolidated numerous cases concerning the impacts of opioid abuses filed against various defendants by counties, cities, hospitals, Native American tribes, third-party payors, and others. In re National Prescription Opiate Litigation (MDL No. 2804) (N.D. Ohio). Included are cases filed against the Company by counties and cities in Michigan, New Jersey, Oregon, Virginia and South Carolina, a third-party payor in Ohio, and a hospital in Texas, class actions filed on behalf of infants born with opioid-related medical conditions in 40 states, and class actions and individual actions filed on behalf of individuals seeking to recover alleged increased insurance costs associated with opioid abuse in 43 states and American Samoa. Claims against the Company filed in federal court outside the MDL have been asserted by certain counties and cities in Florida and Georgia; claims filed by certain cities and counties in New York are pending in state court. Claims against the Company in state courts in New Jersey, Oklahoma, Utah, and Arizona have been dismissed. The Company is defending all of the pending matters.

Members of the Board of Directors, six corporate officers and the Company were defendants in a shareholder derivative action filed in June 2022 related to chicken welfare and alleged breaches of fiduciary duties. Smith, et ano. v. Vachris, et al., Superior Court of the State of Washington, County of King, No, 22-2-08937-7SEA. The complaint sought from the individual defendants' damages, injunctive relief, costs, and attorneys' fees. On March 28, 2023, the court granted the defendants' motion to dismiss the action. The plaintiffs subsequently made a demand that the Board of Directors take various actions, including among other things, pursuing claims against directors and officers of the type asserted in the litigation. A demand review committee of the Board has been appointed to make a recommendation to the Board as to the demand.

In February 2023, Go Green Norcal, LLC filed an arbitration demand against the Company. The demand alleged a breach of a supply agreement and sought unspecified damages and cancellation of a loan from the Company. In March 2023, the Company filed its answer, denying any breach by the Company, along with counterclaims against Go Green and an affiliate for breach of contract, negligent misrepresentation, and an accounting. In August 2023 the plaintiff asserted that its damages exceed $70 million. An award to the plaintiffs of an immaterial amount was paid in February 2024.

Between September 25, 2023, and October 31, 2023, five class action suits were filed against the Company alleging various privacy law violations stemming from pixel trackers on Costco.com. Birdwell v. Costco Wholesale Corp., Case No. T23-1405, Contra Costa County Superior Court; and Scott v. Costco Wholesale Corp., Case No. 2:23-cv-08808 (C.D. Cal.), now consolidated with R.S. v. Costco Wholesale Corp., Case No. 2:23-cv-01628 (W.D. Wash.); Groves, et ano. v. Costco Wholesale Corp., Case No. 2:23-cv-01662 (W.D. Wash.) and Castillo v. Costco Wholesale Corp., under Case No. 2:34-cv-01548 (W.D. Wash.). The Castillo plaintiffs filed a consolidated complaint on January 26, 2024, which seeks damages, equitable relief and attorneys’ fees under various statutes, including the Washington Consumer Protection Act, Washington Privacy Act, Washington Uniform Health Care Information Act, Electronic Communications Privacy Act, California Invasion of Privacy Act, and California Confidentiality of Medical Information Act. The consolidated complaint also alleges breach of implied contract, invasion of privacy, conversion and unjust enrichment. The Company filed a motion to dismiss and demurrer in Birdwell and has not responded to the Castillo consolidated complaint. On January 2, 2024, the Company received a related civil investigative demand from the Washington Attorney General's office. On January 3, 2024, the Company received a related pre-litigation letter from the Los Angeles Office of the County Counsel.

In October 2021 the Company received a notice that the Quebec Health Insurance Board had commenced an inquiry to determine whether the Company had given or received improper payments for drugs that are covered by the province's prescription drug program from drug wholesalers, generic drug manufacturers or the independent pharmacist who owns and operates the pharmacies located in the Company's Quebec locations. The inquiry covers a period beginning January 1, 2017.

In January 2023 the Company received a Civil Investigative Demand from the U.S. Attorney's Office, Western District of Washington, requesting documents. The government is conducting a False Claims Act investigation concerning whether the Company presented or caused to be presented to the federal government for payment false claims relating to prescription medications.

The Company does not believe that any pending claim, proceeding or litigation, either alone or in the aggregate, will have a material adverse effect on the Company’s financial position, results of operations or cash flows; it is possible that an unfavorable outcome of some or all of the matters, however unlikely, could result in a charge that might be material to the results of an individual fiscal quarter or year.

Accounting Policies [Abstract]

Basis of Accounting, Policy

Basis of Presentation

The condensed consolidated financial statements include the accounts of Costco and its wholly-owned subsidiaries. All material inter-company transactions among the Company and its consolidated subsidiaries have been eliminated in consolidation.

These unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q for interim financial reporting pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). While these statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the fiscal year ended September 3, 2023.

Fiscal Period, Policy

Fiscal Year End

The Company operates on a 52/53 week fiscal year basis, with the fiscal year ending on the Sunday closest to August 31. Fiscal 2024 is a 52-week year ending on September 1, 2024. References to the second quarter of 2024 and 2023 relate to the 12-week fiscal quarters ended February 18, 2024, and February 12, 2023. References to the first half of 2024 and 2023 relate to the 24 weeks ended February 18, 2024 and February 12, 2023.

Use of Estimates, Policy

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions take into account historical and forward-looking factors that the Company believes are reasonable. Actual results could differ from those estimates and assumptions.

Reclassification, Policy

Reclassification

Reclassifications were made to the condensed consolidated statement of cash flows for the first half of fiscal 2023 to conform with current year presentation.

Recent Accounting Pronouncements Not Yet Adopted, Policy

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is evaluating the new standard.

In December 2023, the FASB issued ASU 2023-09, which focuses on income tax disclosures by requiring public business entities, on an annual basis, to disclose specific categories in the rate reconciliation, provide information for reconciling items that meet a quantitative threshold, and certain information about income taxes paid. The standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The amendments should be applied on a prospective basis. Retrospective application is permitted. The Company is evaluating the new standard.
