The common-size income statement reveals a period of relative stability in core margins, punctuated by volatility in non-operating items. Overall profitability is characterized by consistent gross profit levels and a gradual increase in auxiliary income streams.
Gross Margin and Cost of Sales
Gross profit as a percentage of net sales generally fluctuates between 23% and 25%. The cost of sales remains the primary expense, consistently ranging from 74.59% to 77.07%. A positive trend is observed toward the end of the analyzed period, with gross profit reaching a peak of 25.41% by July 2026, indicating improved cost management or pricing strategies.
Revenue Diversification
Membership and other income demonstrate a steady upward trend as a proportion of net sales. Starting at approximately 0.71% in early 2020, this figure frequently exceeds 0.90% in later periods, peaking at 1.18% in April 2026. This suggests a growing reliance on high-margin, non-sales revenue streams to supplement the top line.
Operating Performance
Operating income margins exhibit significant volatility, ranging from a low of 1.78% in October 2022 to a high of 5.26% in July 2021. This variance is largely driven by fluctuations in operating, selling, general, and administrative expenses, which typically oscillate between 19.93% and 22.78% of net sales. A recovery in operating efficiency is evident in the final period, where operating income reaches 5.04%.
Non-Operating Items and Net Profitability
Net income is heavily influenced by the volatility of other gains and losses, which cause sharp quarterly swings in income before taxes. For instance, significant losses occurred in January 2021 (-3.70%) and October 2023 (-2.98%), while notable gains were recorded in July 2023 (2.44%). Despite these swings, consolidated net income attributable to Walmart remains positive in most quarters, typically residing between 2% and 4% of net sales. Interest expenses have remained relatively stable, though a significant reduction to 0.09% of net sales is noted in July 2026.
