Walmart U.S. - quarterly financial highlights 9 Sales • Net sales increased 4.3%, or approximately $3.2 billion. • Comp sales1 increased 2.7% led by a strong comp traffic of 1.5%. eCommerce contributed approximately 80 basis points to segment comp sales growth. Hurricane-related impacts benefited comp sales by approximately 30-50 basis points. On a 2-year stack basis, comp sales and traffic were up 3.9% and 2.2%, respectively. • Strong performance in food categories continued with comp sales, traffic and unit growth across categories. • Market inflation in food for the third quarter was around or slightly less than the second quarter. • Strong growth in multi-channel sales continued in the quarter, including online grocery and general merchandise pickup in store. Gross Margin • Gross margin rate declined 36 basis points in the quarter. The margin rate was pressured by the continued execution of our price investment strategy and the mix effects from our growing eCommerce business. In addition, we estimate that hurricane-related impacts contributed to about one-third of the overall decline. Expenses • Segment operating expenses leveraged 10 basis points, despite hurricane-related expenses. Physical stores leveraged expenses for the 3rd consecutive quarter and were partially offset by investments in eCommerce and technology. Inventory • Total inventory was flat versus last year and comp store inventory declined approximately 3.5%, while in-stock levels remained high. Format growth • We opened 2 Supercenters and 2 Neighborhood Markets in the period. We also remodeled 208 stores. • As of the end of Q3, online grocery was offered in over 1,100 locations, which represents more than 200 additional locations since Q2. 1 Comp sales for the 13-week period ended October 27, 2017, excluding fuel. Including fuel, Walmart U.S. comparable sales grew 2.8%. See press release located at www.stock.walmart.com and reconciliations at the end of this presentation regarding non-GAAP financial measures.

Walmart U.S. - quarterly merchandise highlights Category Comp Comments Grocery1 + low single-digit Food and consumables had solid comp sales driven by strong customer traffic, increased innovation, and improvement in private brands.

Walmart International - quarterly financial highlights 12 Sales • Net sales on a constant currency basis increased 2.5 percent. • Reported net sales increased 4.1 percent, which included a benefit of approximately $450 million from currency. • The divestitures of Suburbia and Yihaodian created a headwind to sales of nearly $560 million when compared to last year. • Ten of 11 markets delivered positive comp sales. Gross Margin • Gross margin rate declined 18 basis points primarily driven by planned price investments in certain markets. Operating income • Operating income declined 12.2 percent on a constant currency basis and 7.8 percent on a reported basis. • The decrease in operating income is due to the ~$150 million impairment related to our decision to exit certain properties in one of our markets as well as lapping last year’s gain of $86 million from the sale of several shopping malls in Chile. Inventory • During the quarter, inventory grew slower than sales. 1 See press release located at www.stock.walmart.com and reconciliations at the end of this presentation regarding non-GAAP financial measures.

Non-GAAP measures - ROI We include Return on Assets ("ROA"), which is calculated in accordance with generally accepted accounting principles in the U.S. ("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 potential 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 5.8 percent and 7.3 percent for the trailing twelve months ended October 31, 2017 and 2016, respectively. ROI was 14.7 percent and 15.0 percent for the trailing twelve months ended October 31, 2017 and 2016, respectively. The decline in ROA was primarily due to the loss on extinguishment of debt and the decrease in operating income. The decline in ROI was primarily due to the decrease in operating income. 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, plus a rent factor equal to the rent for the fiscal year or trailing 12 months multiplied by a factor of 8. When we have discontinued operations, we exclude the impact of the discontinued operations. 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. In addition, we include a factor of 8 for rent expense that estimates the hypothetical capitalization of our operating leases. As mentioned above, we consider return on assets 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; and incorporates a factor of rent 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

Non-GAAP measures - free cash flow We define free cash flow as net cash provided by operating activities in a period minus payments for property and equipment made in that period. We had net cash provided by operating activities of $17.1 billion and $19.8 billion for the nine months ended October 31, 2017 and 2016, respectively. We generated free cash flow of $10.2 billion and $12.3 billion for the nine months ended October 31, 2017 and 2016, respectively. The decreases in net cash provided by operating activities and free cash flow were due to the timing of payments and an increase in incentive payments, as well as lapping prior year's improvements in working capital management. 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. 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. Nine Months Ended October 31, (Dollars in millions) 2017 20161 Net cash provided by operating activities $ 17,060 $ 19,781 Payments for property and equipment (capital expenditures) -6,908 -7,459 Free cash flow $ 10,152 $ 12,322 Net cash used in investing activities2 $ -5,871 $ -11,050 Net cash used in financing activities -11,416 -11,272 1 Reclassifications have been made due to the adoption of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. 2 "Net cash used in investing activities" includes payments for property and equipment, which is also included in our computation of free cash flow. 22

1 Change versus prior year comparable period. Non-GAAP measures - constant currency 23 In discussing our operating results, the term currency exchange rates refers to the currency exchange rates we use to convert the operating results for all countries where the functional currency is not the U.S. dollar ("non-USD entities") into U.S. dollars. 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. 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 and without the impact of acquisitions of non-USD entities, if any, until such acquisitions are included in both comparable periods.
