For comparability, we revised this metric for FY19 and have provided a quarterly summary on our website at http://www.stock.walmart.com. 8

Walmart U.S. - quarterly financial highlights Sales • Comp sales1 increased 2.8%, the 20th consecutive quarter of positive comps. Comp ticket increased 2.2% and comp transactions grew 0.6%. eCommerce sales grew 37% and contributed approximately 140 basis points to segment comp sales growth. Online grocery was a meaningful contributor to eCommerce growth. • On a two-year stacked basis, comp sales were up 7.3%, the strongest growth in more than 10 years. • Sales trends were strong despite weather-related challenges in certain general merchandise categories. Gross profit rate • Gross profit rate was better than expected despite a decline of 22 basis points. Continued price investments, increased seasonal markdowns and the growing mix of eCommerce pressured gross profit but were partially offset by favorable merchandise mix, including strength in private brands, and lower transportation costs. The eCommerce team delivered gross profit rate improvement year over year. Expenses • Operating expenses leveraged 29 basis points. Both the stores and eCommerce teams delivered expense leverage. Physical stores leveraged expenses for the 10th consecutive quarter due to strong productivity improvements, partially offset by growth of eCommerce in the segment. Inventory • Comp store inventory was up 2.5% and total inventory increased 4.0%. This was due in part to increased in-transit inventory, strategic investments in certain categories and increased mirroring of inventory in our eCommerce fulfillment centers. We feel good about the quality of our inventory position. Format growth • We had a net opening of 1 Supercenter and closed 1 Neighborhood Market. We also remodeled over 150 stores. • As of Q2, we had more than 2,700 grocery pickup locations, more than 1,100 stores with same-day grocery delivery and nearly 1,200 pickup towers. 1 Comp sales for the 13-week period ended July 26, 2019, excluding fuel. 9

Walmart U.S. - quarterly merchandise highlights Category Comp Comments Momentum continued in food and consumables with the strongest two- year stacked comp in nearly 10 years. Snack & beverages, fresh 1 foods, pets and paper goods were particularly strong. Customers are Grocery + mid single-digit responding favorably to our pricing strategy, omni-channel offer and enhanced private brands. Comp ticket was affected by slight deflation in food for the quarter and modest inflation in consumables. Pharmacy comp sales increased primarily due to branded drug Health & wellness + mid single-digit inflation and an increase in 90-day script counts. General Home, toys and wireless delivered strong results but were partially merchandise2 + low single-digit offset by softness in weather-sensitive categories like lawn & garden and apparel. 1 Includes food and consumables. 2 General merchandise includes entertainment, toys, hardlines, apparel, home and seasonal. 10

Walmart International - quarterly financial highlights Sales • Positive comp sales in nine of 10 markets, including the four largest markets - Mexico, U.K., Canada and China. The later timing of Easter this year benefited comp sales in Mexico and resulted in positive comp sales in the U.K. • The deconsolidation of Brazil was a headwind for the quarter but was offset by sales from Flipkart. • Currency negatively affected net sales by $1.3 billion. Gross profit • Gross profit rate declined 157 basis points on a reported basis, primarily due to Flipkart. A change in mix towards lower margin categories and price investments were also contributing factors in certain other markets. Expenses • Operating expenses leveraged 36 basis points on a reported basis and 24 basis points in constant currency. Lapping certain store closure charges from the prior year, positive comp sales and cost discipline across multiple markets contributed to the performance. Operating income • Operating income declined 29.6% on a reported basis and declined 27.3% in constant currency, primarily due to Flipkart. ◦ Timing of the Easter holiday positively affected operating income in certain markets. • Changes in currency rates resulted in a $29 million headwind to operating income. Inventory • During the quarter, inventory growth outpaced the sales decline on a reported basis. 12

Walmart International - key market highlights Walmex • Net sales increased 6.3% and comp sales increased 4.8%, led by strength in Mexico. ◦ In Mexico, comp sales increased 5.5% or 12.0% on a two-year stacked basis. ◦ Opened 32 new stores across Mexico and Central America. • Comp sales growth continued to outpace ANTAD1 self-service and clubs; Walmex has now outperformed the market for 18 consecutive quarters. ◦ Increased eCommerce sales in Mexico by 50%. • Gross profit rate declined primarily as a result of margin softness in general merchandise categories and headwinds from logistics. • Operating expense deleveraged under US GAAP, primarily as a result of lapping an economic benefit related to last year's derivative gains. Excluding this item, operating expenses would have leveraged. • Operating income increased slightly as lower gross margins pressured results. China • Net sales increased 4.7% and comp sales increased 3.0%. • Sam's Club delivered double-digit comp sales growth. • Gross profit rate declined as a result of a greater mix of lower margin Sam's Club sales as well as additional price investment in fresh categories. • Operating expense leverage is primarily due to higher sales growth and store cost savings resulting from our “operate for less” program. • Operating income increased primarily as a result of higher sales growth and operating expense leverage. 1 ANTAD - Asociación Nacional de Tiendas de Autoservicio y Departamentales; The National Association of Supermarkets and Department Stores 14

Walmart International - key market highlights Canada • Net sales increased 0.4% and comp sales increased 1.2%. ◦ Comp sales growth benefited from strength in grocery and fresh offset by softer sales in general merchandise and apparel. ◦ The company finalized the sale of Walmart Canada Bank on April 1, 2019, which resulted in a headwind to sales for the quarter of 95 basis points. • Gross profit rate increased primarily as a result of improved margins in weekly shop categories, including food, consumables, and health and wellness, partially offset by the divestiture of Walmart Canada Bank. • Operating expenses grew at a faster rate than net sales for the quarter. Legislative changes to minimum wage requirements pressured operating expenses. • Operating income declined primarily as a result of legislative changes to minimum wage requirements and the sale of Walmart Canada Bank on April 1, 2019. U.K. • Net sales increased 1.3% and comp sales increased 0.5%. ◦ The later timing of Easter this year resulted in positive comp sales. ◦ The uncertainty surrounding Brexit continues to affect customers in this market. ◦ Lapping difficult comparisons from last year, primarily warmer weather. ◦ Sales for online grocery outpaced the market for the quarter, according to Kantar. • Gross profit rate declined primarily as a result of increased fuel sales with lower margins, softness in higher-margin general merchandise and price investments. • Operating expense leverage is primarily the result of cost savings programs. • Operating income declined primarily as a result of the decline in gross profit. • Continue to make progress on strategic priorities with better price competitiveness and shelf availability. 15

Tobacco sales negatively affected comparable sales by 300 basis points for Q2. NP - Not provided 16

Sam's Club - quarterly financial highlights Sales • Comp sales1 increased 1.2% and comp transactions grew 5.0%. Tobacco negatively affected comp sales by approximately 300 basis points. • eCommerce sales increased approximately 35%. Gross profit • Gross profit rate increased 11 basis points and 5 basis points, with and without fuel, respectively. Higher margins on fuel positively affected gross profit. Without fuel, gross profit rate benefited from a reduction in sales of tobacco and higher co-branded credit card income. These benefits were partially offset by investments in price. Operating expenses • Operating expenses as a percentage of net sales decreased 21 and 14 basis points, with and without fuel, respectively. Operating expense leverage is primarily the result of lower labor-related costs, partially offset by a reduction in sales of tobacco. Membership income • Membership income increased 2.8%. Trends in membership continue to improve. Compared to last year, the total number of members, overall renewal rates and renewal rates for Plus members all increased for the quarter. Inventory • Inventory increased 2.5% primarily due to accelerated buying in certain categories, as well as additional eCommerce fulfillment centers. 1 Comp sales for the 13-week period ended July 26, 2019, excluding fuel. 17

Sam's Club - quarterly category highlights Category Comp Comments Fresh / Freezer / Cooler + mid single-digit Produce and floral, deli and frozen performed well. Grocery and beverage + mid single-digit Snacks, soda, coffee, chips, and candy performed well. Experienced broad-based strength, including paper goods, laundry & home care and pet Consumables + high single-digit supplies. Home and apparel + low single-digit Outdoor living, kitchen electrics, and nursery & gardening performed well. Technology, office and Soft sales of consumer electronics and office supplies were partially offset by improved entertainment - low single-digit sales of mobile phones. Health and wellness + mid single-digit OTC performed well. 18

Non-GAAP measures - ROI We include Return on Assets ("ROA"), which is calculated in accordance with U.S. generally accepted accounting principles ("GAAP") as well as Return on Investment ("ROI") as measures to assess returns on assets. Management believes ROI is a meaningful measure to share with investors because it helps investors assess how effectively Walmart is deploying its assets. Trends in ROI can fluctuate over time as management balances long-term strategic initiatives with possible short-term impacts. We consider ROA to be the financial measure computed in accordance with GAAP that is the most directly comparable financial measure to our calculation of ROI. ROA was 6.0 percent and 2.9 percent for the trailing twelve months ended July 31, 2019 and 2018, respectively. The increase in ROA was primarily due to the increase in consolidated net income over the trailing twelve months, primarily resulting from lapping the $4.5 billion net loss in fiscal 2019 related to the sale of the majority stake in Walmart Brazil and the restructuring and impairment charges in the fourth quarter of fiscal 2018. ROI was 14.3 percent and 13.8 percent for the trailing twelve months ended July 31, 2019 and 2018, respectively. The increase in ROI was due to the increase in operating income over the trailing twelve months primarily as a result of lapping the restructuring and impairment charges in the fourth quarter of fiscal 2018. The denominator remained relatively flat as the $11.6 billion increase in average total assets due to the Flipkart Acquisition was offset by the decrease in average invested capital resulting from the removal of the eight times rent factor upon adoption of ASU 2016-02, Leases ("ASU 2016-02") since operating lease right of use assets are now included in total assets. We define ROI as adjusted operating income (operating income plus interest income, depreciation and amortization, and rent expense) for the trailing 12 months divided by average invested capital during that period. We consider average invested capital to be the average of our beginning and ending total assets, plus average accumulated depreciation and average amortization, less average accounts payable and average accrued liabilities for that period. Upon adoption of ASU 2016-02, rent for the trailing 12 months multiplied by a factor of 8 is no longer included in the calculation of ROI on a prospective basis as operating lease assets are now capitalized. For fiscal 2020, lease related assets and associated accumulated amortization are included in the denominator at their carrying amount as of the current balance sheet date, rather than averaged, because they are no longer directly comparable to the prior year calculation which included rent for the trailing 12 months multiplied by a factor of 8. A two-point average will be used for leased assets beginning in fiscal 2021, after one full year from the date of adoption of the new lease standard. Further, beginning prospectively in fiscal 2020, rent expense in the numerator excludes short-term and variable lease costs as these costs are not included in the operating lease right of use asset balance. 19

Non-GAAP measures - ROI cont. Prior to adoption of ASU 2016-02, we defined ROI as adjusted operating income (operating income plus interest income, depreciation and amortization, and rent expense) for the trailing 12 months divided by average invested capital during that period. We considered average invested capital to be the average of our beginning and ending total assets, plus average accumulated depreciation and average amortization, less average accounts payable and average accrued liabilities for that period, plus a rent factor equal to the rent for the fiscal year or trailing 12 months multiplied by a factor of 8, which estimated the hypothetical capitalization of our operating leases. Because the new lease standard was adopted prospectively as of February 1, 2019, our calculation of ROI for the comparable fiscal 2019 period was not recast. Our calculation of ROI is considered a non-GAAP financial measure because we calculate ROI using financial measures that exclude and include amounts that are included and excluded in the most directly comparable GAAP financial measure. For example, we exclude the impact of depreciation and amortization from our reported operating income in calculating the numerator of our calculation of ROI. As mentioned above, we consider ROA to be the financial measure computed in accordance with generally accepted accounting principles most directly comparable to our calculation of ROI. ROI differs from ROA (which is consolidated net income for the period divided by average total assets for the period) because ROI: adjusts operating income to exclude certain expense items and adds interest income; adjusts total assets for the impact of accumulated depreciation and amortization, accounts payable and accrued liabilities to arrive at total invested capital. Because of the adjustments mentioned above, we believe ROI more accurately measures how we are deploying our key assets and is more meaningful to investors than ROA. Although ROI is a standard financial measure, numerous methods exist for calculating a company's ROI. As a result, the method used by management to calculate our ROI may differ from the methods used by other companies to calculate their ROI. 20

We had net cash provided by operating activities of $11.2 billion for the six months ended July 31, 2019, which was relatively flat when compared to $11.1 billion for the six months ended July 31, 2018. We generated free cash flow of $6.3 billion for the six months ended July 31, 2019, which declined when compared to $6.8 billion for the twelve months ended July 31, 2018 due primarily to $0.6 billion in increased capital expenditures. Free cash flow is considered a non-GAAP financial measure. Management believes, however, that free cash flow, which measures our ability to generate additional cash from our business operations, is an important financial measure for use in evaluating the company's financial performance. Free cash flow should be considered in addition to, rather than as a substitute for, consolidated net income as a measure of our performance and net cash provided by operating activities as a measure of our liquidity. Additionally, Walmart's definition of free cash flow is limited, in that it does not represent residual cash flows available for discretionary expenditures, due to the fact that the measure does not deduct the payments required for debt service and other contractual obligations or payments made for business acquisitions. Therefore, we believe it is important to view free cash flow as a measure that provides supplemental information to our Consolidated Statements of Cash Flows. Although other companies report their free cash flow, numerous methods may exist for calculating a company's free cash flow. As a result, the method used by Walmart's management to calculate our free cash flow may differ from the methods used by other companies to calculate their free cash flow. The following table sets forth a reconciliation of free cash flow, a non-GAAP financial measure, to net cash provided by operating activities, which we believe to be the GAAP financial measure most directly comparable to free cash flow, as well as information regarding net cash used in investing activities and net cash used in financing activities.

Non-GAAP measures - constant currency In discussing our operating results, the term currency exchange rates refers to the currency exchange rates we use to convert the operating results for countries where the functional currency is not the U.S. dollar into U.S. dollars or for countries experiencing hyperinflation. We calculate the effect of changes in currency exchange rates as the difference between current period activity translated using the current period's currency exchange rates and the comparable prior year period's currency exchange rates. Additionally, no currency exchange rate fluctuations are calculated for non-USD acquisitions until owned for 12 months. Throughout our discussion, we refer to the results of this calculation as the impact of currency exchange rate fluctuations. When we refer to constant currency operating results, this means operating results without the impact of the currency exchange rate fluctuations. The disclosure of constant currency amounts or results permits investors to better understand Walmart's underlying performance without the effects of currency exchange rate fluctuations. The table below reflects the calculation of constant currency for total revenues, net sales and operating income for the three and six months ended July 31, 2019.

Non-GAAP measures - adjusted EPS Adjusted diluted earnings per share attributable to Walmart (Adjusted EPS) is considered a non-GAAP financial measure under the SEC's rules because it excludes certain amounts not excluded in the diluted earnings per share attributable to Walmart calculated in accordance with GAAP (EPS), the most directly comparable financial measure calculated in accordance with GAAP. Management believes that Adjusted EPS is a meaningful measure to share with investors because it best allows comparison of the performance for the comparable period. In addition, Adjusted EPS affords investors a view of what management considers Walmart's core earnings performance and the ability to make a more informed assessment of such core earnings performance. We have calculated Adjusted EPS for the three months by adjusting EPS for the unrealized gains and losses on the company's equity investment in JD.com. We adjust for these unrealized gains and losses because although the Company's investment in JD.com was a strategic decision for the company's retail operations in China, management's measurement of that strategy is primarily focused on the Walmart China financial results rather than the investment value of JD.com. Additionally, management does not forecast changes in fair value of its equity investments. Accordingly, management adjusts EPS for the unrealized JD.com investment gains and losses.

Non-GAAP measures - adjusted EPS As previously disclosed in our second quarter ended July 31, 2018 press release, we have calculated Adjusted EPS for the three months ended July 31, 2018 by adjusting EPS for the following: (1) the loss on sale of the majority stake in Walmart Brazil, (2) an adjustment to the provisional amount recorded in the second quarter of fiscal 2019 related to Tax Reform and (3) unrealized gains and losses on our JD.com investment. The provisional measurement period related to Tax Reform ended in the fourth quarter of fiscal 2019. The most directly comparable financial measure calculated in accordance with GAAP is EPS for the three months ended July 31, 2018.
