Net Sales
Remained constant as the baseline reference of 100% in all periods, serving as the basis for percentage analysis of other financial items.
Merchandise Costs
Displayed high and relatively stable proportions, ranging approximately between -88.4% and -89.8% of net sales. There was minor fluctuation but no significant trend, indicating consistent cost of goods sold relative to sales over time.
Gross Margin
Showed relative stability around 10.2% to 11.5% of net sales. Some minor variability was observed, with peaks around early 2021 and small declines around 2022, but generally maintained a steady margin.
Membership Fees
Exhibited a generally downward trend over the timeline from approximately 2.21% down to near 1.87%, followed by a modest rebound to about 2% in the latest periods. This suggests slight fluctuations in membership fee contributions relative to sales, possibly influenced by pricing or membership base changes.
Selling, General and Administrative Expenses (SG&A)
Experienced a gradual reduction as a percentage of net sales, starting near -10.19% and improving to a lower range around -8.53% to -9.2%. This indicates enhanced operating efficiency or cost control efforts over the observed periods.
Operating Income
Generally increased over time, starting at roughly 2.77% of net sales and rising to above 4% in the most recent quarters. This improvement suggests stronger operational profitability, possibly due to a combination of consistent gross margins and controlled SG&A expenses.
Interest Expense
Remained relatively stable and low, fluctuating marginally between -0.1% and -0.06%, reflecting consistent financing costs relative to sales.
Interest Income and Other, Net
Varied throughout the periods, initially positive with some dips into negligible negative values, and showing a notable upward trajectory in recent periods, reaching up to 0.38% of net sales. This points to increasing non-operating income contributions enhancing overall profitability.
Other Income (Expense)
Demonstrated fluctuations but generally shifted from small negative or neutral values to more positive contributions, reaching about 0.31% in recent quarters, supporting income improvement outside of core operations.
Income Before Income Taxes
Showed an upward trend, increasing from about 2.73% of net sales to over 4% in the latest periods, reflecting the cumulative effect of improved operating income and non-operating income gains.
Provision for Income Taxes
Fluctuated between around -0.46% and -1.09% of net sales with no definitive improving or deteriorating trend, suggesting variable tax rates or tax expense in absolute terms relative to income fluctuations.
Net Income Including Noncontrolling Interests
Generally increased from approximately 2.26% to 3.07%, indicating improved net profitability over time. Periodic dips occurred but were followed by recoveries aligning with the operating income and tax provisions trends.
Net Income Attributable to Noncontrolling Interests
Remained minimal and stable, close to -0.03% to -0.05%, with some missing data in later periods, indicating that noncontrolling interests have limited impact on net income trends.
Net Income Attributable to Costco
Mirrored the trend of net income including noncontrolling interests, gradually increasing from roughly 2.24% to over 3%, reflecting enhanced profitability available to the company’s shareholders.
