Exhibit 99.1

Walmart reports second quarter EPS of $0.97, ahead of First Call consensus;

Company raises full-year EPS guidance

Highlights

BENTONVILLE, Ark., Aug. 17, 2010 — Wal-Mart Stores, Inc. (NYSE: WMT) today reported second quarter sales and earnings for the period ended July 31, 2010. Net sales for the second quarter of fiscal year 2011 were $103 billion, an increase of 2.8 percent from $100 billion in the second quarter last year. Net sales for the second quarter included a currency exchange rate benefit of $857 million. On a constant currency basis, consolidated net sales increased 2.0 percent. Income from continuing operations attributable to Walmart for the quarter increased to $3.6 billion from $3.5 billion in the second quarter last year.

Diluted earnings per share from continuing operations attributable to Walmart for the second quarter of fiscal year 2011 were $0.97, with a benefit of approximately $0.01 from currency exchange rates. This compares to diluted EPS of $0.89 in the second quarter last year, as adjusted from the previously reported $0.88.

Effective with the second quarter of fiscal year 2011, Walmart changed the methodology for valuing its inventory to allow for more granularity. As a result, the change in the inventory value adjusts the financial results reported last fiscal year. The company is providing adjusted financial statements on its website to reflect these changes.

“We continue to focus on our priorities of growth, leverage and returns. Despite the ongoing challenges of the global economy, we continue to grow our earnings and are reporting $0.97 per share today,” said Mike Duke, Wal-Mart Stores, Inc. president and chief executive officer. “We are raising our full year guidance to a range of $3.95 to $4.05. Our teams leveraged operating expenses for the third consecutive quarter, through their commitment to the productivity loop.

“The slow economic recovery will continue to affect our customers, and we expect they will remain cautious about spending,” Duke added. “Walmart is committed to our mission of saving people money so they can live better.”

Walmart continues to grow around the world, and the company added almost 5 million square feet of retail space this quarter, with more than 60 percent of the square footage growth in Walmart International.

“Our international business continues to be an impressive growth engine, and Walmart International grew operating income faster than sales,” Duke said.

The company ended the second quarter with free cash flow² of approximately $4.5 billion, compared to $4.2 billion in the prior year. ROI for the trailing 12 months ended July 31, 2010 was 19.0 percent, up from 18.4 percent for the comparable period last year.

“Our goal is to provide a consistently high return and ROI is extremely healthy,” said Tom Schoewe, executive vice president and chief financial officer. “We continue to deliver solid operating performance.”

Earnings Guidance

For the third quarter of this fiscal year, the company forecasts diluted earnings per share from continuing operations attributable to Walmart to range from $0.87 to $0.91, as compared to an as adjusted $0.82 per share last year. The company’s updated full year guidance of $3.95 to $4.05 earnings per share is an increase from the previous range of $3.90 to $4.00 per share. This new guidance assumes that currency exchange rates remain at current levels.

“We are raising full year EPS guidance today due to the strength of our underlying operating performance of our first two quarters, despite the challenges facing Walmart U.S. in the short term and the current economy,” said Schoewe. “In the second quarter, we delivered on our promise to leverage expenses, and this commitment remains a strategic priority throughout the company. We plan to continue leveraging expenses.

“Through the first half of this fiscal year, we have returned more than $9.4 billion to shareholders in the form of share repurchase ($7.1 billion) and dividends ($2.3 billion),” Schoewe said.

The company’s board of directors approved a new $15 billion share repurchase program June 4, which replaced the previous $15 billion plan. Walmart repurchased $4.1 billion in shares during the second quarter of this fiscal year.

Operating Segment Details

Data in the condensed consolidated financial statements included in this news release are based on the fiscal quarters ended July 31, 2010 and 2009. As part of an operational realignment, the Walmart units and Sam’s Clubs in Puerto Rico moved from the Walmart International segment to the respective Walmart U.S. and Sam’s Club segments, effective this fiscal year.

U.S. comparable store sales

The company reports U.S. comparable store sales in this earnings release based on its 13-week and 26-week retail calendar periods ended July 30, 2010 and July 31, 2009, as follows:

Comparable store sales figures for Walmart U.S. improved by the end of the 13-week period ended July 30, 2010, with traffic trends showing sequential improvement during the period.

The Walmart U.S. operating segment, now led by President and CEO Bill Simon, remains focused on improving sales and customer traffic. The leadership team is working to ensure that the merchandise assortment is relevant for their customers, that Walmart will lead the market on price, and that they will strengthen their relationships with suppliers.

For the 13-week period from Sat., July 31, through Fri., Oct 29, 2010, which is comparable to the company’s third fiscal quarter, Walmart U.S. expects comparable store sales to range between -2.0 percent and 1.0 percent, as compared to a 0.5 percent decline for the comparable period last year.

Sam’s Club delivered 1.0 percent comparable club sales without fuel for the 13-week period ended July 30, 2010, with average ticket, excluding fuel, for this 13-week period increased for both Business and Advantage members.

4

Sam’s Club expects comparable club sales without fuel during the third quarter 13-week period to range from flat to an increase of 2.0 percent, which compares to a 0.1 percent increase without fuel in the comparable period last year. Brian Cornell, president and CEO of Sam’s Club, and his leadership team remain focused on driving sales through ongoing improvement in merchandise quality and relevance, as well as continued focus on generating higher membership.

Both Walmart U.S. and Sam’s Club will report comparable sales for the 13-week period on Nov. 16, 2010, when the company reports third quarter results.

Notes

Constant currency results are calculated by translating current year results using prior year exchange rates.

Effective Feb. 1, 2010, the company made certain changes to its internal management reporting that impacted only our segment reporting. Prior year amounts have been reclassified to conform to the current year’s presentation. These changes include allocating to the segments certain information systems expenses previously included in unallocated corporate overhead and, in connection with an operational alignment, moving the Puerto Rico operations from the Walmart International segment to both the respective Walmart U.S. and Sam’s Club segments. The Walmart U.S. segment now includes the company’s mass merchant concept in the United States and Puerto Rico operating primarily under the “Walmart” or “Wal-Mart” brand, as well as walmart.com. Walmart International now consists of the company’s operations outside the United States and Puerto Rico. The Sam’s Club segment now includes the warehouse membership clubs in the United States and Puerto Rico, as well as samsclub.com.

In addition, effective May 1, 2010, the company implemented a new enterprise resource planning (“ERP”) system for its operations in the United States, Canada and Puerto Rico. Concurrent with this implementation and the increased system capabilities, the company changed its level of applying the retail method of accounting for inventory from 13 divisions to 49 departments. The company believes the change is preferable because applying the retail method of accounting for inventory at the departmental level better segregates merchandise with similar cost-to-retail ratios and turnover, as well as provides a more accurate cost of goods sold and ending inventory value at the lower of cost or market for each reporting period. The retrospective application of this accounting change impacted both segment and consolidated operating income, as well as consolidated net income for all comparable periods presented.

Reconciliation of and Other Information regarding Non-GAAP Financial Measures

(Unaudited)

(In millions, except per share data)

The following information provides reconciliations of non-GAAP financial measures presented in the press release to which this reconciliation is attached to the most nearly comparable financial measures calculated and presented in accordance with generally accepted accounting principles (“GAAP”). The company has provided the non-GAAP financial information presented in the press release, which is not calculated or presented in accordance with GAAP, as information supplemental and in addition to the financial measures presented in the press release that are calculated and presented in accordance with GAAP. Such non-GAAP financial measures should not be considered superior to, as a substitute for or as an alternative to, and should be considered in conjunction with, the GAAP financial measures presented in the press release. The non-GAAP financial measures in the press release may differ from similar measures used by other companies.

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 generated free cash flow of $4.5 billion and $4.2 billion for the six months ended July 31, 2010 and 2009, respectively. Our free cash flow during the current period was positively impacted by a temporary increase in accounts payable, as a result of timing related to our payment cycles, partially offset by our increased investment in inventory.

Free cash flow is considered a non-GAAP financial measure under the SEC’s rules. 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, income from continuing operations as a measure of our performance and net cash provided by operating activities as a measure of our liquidity.

Additionally, our 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 entire statement 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 our management to calculate free cash flow may differ from the methods other companies use to calculate their free cash flow. We urge you to understand the methods used by another company to calculate its free cash flow before comparing our free cash flow to that of such other company.

The following table sets forth a reconciliation of free cash flow, a non-GAAP financial measure, to net cash provided by operating activities, a GAAP measure, which we believe to be the GAAP financial measure most directly comparable to free cash flow, for the six months ended July 31, 2010 and 2009, as well as information regarding net cash used in investing activities and net cash used in financing activities in those periods.

Calculation of Return on Investment and Return on Assets

Management believes return on investment (“ROI”) is a meaningful metric to share with investors because it helps investors assess how effectively Walmart is employing its assets. Trends in ROI can fluctuate over time as management balances long-term potential strategic initiatives with any possible short-term impacts.

ROI was 19.0 percent and 18.4 percent for the trailing 12-month periods ended July 31, 2010 and 2009, respectively. The period-over-period increase in ROI is principally due to our solid operating performance, as a result of our focus on expense leverage.

We define ROI as adjusted operating income (operating income plus interest income, depreciation and amortization and rent expense) for the fiscal year or trailing twelve 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 of continuing operations plus accumulated depreciation and amortization less accounts payable and accrued liabilities for that period, plus a rent factor equal to the rent for the fiscal year or trailing twelve months multiplied by a factor of eight.

ROI is considered a non-GAAP financial measure under the SEC’s rules. We consider return on assets (“ROA”) to be the financial measure computed in accordance with GAAP that is the most directly comparable financial measure to ROI as we calculate that financial measure. ROI differs from ROA (which is income from continuing operations for the fiscal year or trailing twelve months divided by average total assets of continuing operations for the period) because ROI: adjusts operating income to exclude certain expense items and adds interest income; adjusts total assets from continuing operations 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.

Although ROI is a standard financial metric, numerous methods exist for calculating a company’s ROI. As a result, the method used by Walmart’s management to calculate ROI may differ from the methods other companies use to calculate their ROI. We urge you to understand the methods used by another company to calculate its ROI before comparing our ROI to that of such other company.

The calculation of ROI along with reconciliation to the calculation of ROA, the most comparable GAAP financial measurement, is as follows:
