Exhibit 99.1

Office Depot, Inc. Announces Second Quarter 2015 Results

Continues to Deliver Substantial Improvement in Operating Income

Accelerates U.S. Retail Store Portfolio Optimization

Boca Raton, Fla., August 4, 2015 — Office Depot, Inc. (“Office Depot”, or the “company”) (NASDAQ: ODP), a leading global provider of office products, services, and solutions, which entered into a definitive agreement on February 4, 2015 to be acquired by Staples, Inc. (“Staples”), today announced results for the second quarter ended June 27, 2015.

“In the second quarter we significantly improved operating income versus last year, primarily due to continued excellent execution on our merger integration, synergies and efficiencies, and positive same-store sales growth,” said Roland Smith, chairman and chief executive officer for Office Depot. “While total company sales declined compared to prior year, driven primarily by planned store closures and foreign currency translation, continued success in the consolidation of our U.S. retail store portfolio and increased operational effectiveness drove positive quarterly same-store sales growth for the first time in many years. We are especially pleased with our performance in light of the inherent disruption associated with the pending acquisition by Staples. We continue to focus on executing our Critical Priorities and remain on track with the Office Depot/OfficeMax merger integration and our European restructuring.”

Smith added, “We are pleased that our shareholders overwhelmingly approved the pending acquisition by Staples on June 19th. We remain on track with the regulatory review process, and we continue to anticipate this transaction will close by the end of 2015.”

Adjusted (non-GAAP) Results ⁽¹⁾

Total adjusted sales in the second quarter of 2015 declined 3% compared to the prior year period, excluding the impact of foreign currency translation, U.S. retail store closures, and sales from the company’s interest in the Grupo OfficeMax joint venture which was sold in August 2014.

Adjusted net income attributable to Office Depot, Inc. for the second quarter of 2015 was $32 million, or $0.06 earnings per share, compared to an adjusted net loss of $12 million, or $0.02 loss per share, in the second quarter of 2014.

Divisional Results

North American Retail Division

Retail Division sales were $1.3 billion in the second quarter of 2015, a decline of 8% compared to the prior year period, primarily due to planned store closures in the fiscal twelve months through June 27, 2015. Same-store sales increased 1%, driven largely by transferred sales from closed stores and increased operational effectiveness.

2

Retail Division operating income was $42 million, or 3.1% of sales, in the second quarter of 2015 compared to an operating loss of $6 million, or 0.4% of sales, in the second quarter of 2014. The improvement from the prior year quarter resulted largely from a decrease in occupancy costs driven by store closures, a decrease in selling, general and administrative expenses including advertising and payroll, as well as favorable legal settlements and an improvement in the gross margin rate; all of which were partially offset by the negative flow-through impact of lower sales.

Office Depot ended the second quarter of 2015 with a total of 1,626 retail stores in the North American Retail Division. During the quarter, the company closed 99 stores.

North American Business Solutions Division

Business Solutions Division sales were $1.4 billion in the second quarter of 2015, a decline of 4% compared to the prior year period. Sales declined 3% in constant currency. The sales decline was mostly attributable to the scheduled transition out of certain large customers that purchased under a legacy OfficeMax Tier 1 buying arrangement and lower sales in Canada.

Business Solutions Division operating income was $63 million, or 4.4% of sales, in the second quarter of 2015 compared to $59 million, or 4.0% of sales, in the second quarter of 2014. The increase compared to the prior year quarter was driven by lower selling, general and administrative expenses including payroll and advertising, partially offset by the negative flow-through impact of lower sales.

International Division

International Division sales were $0.7 billion in the second quarter of 2015, a decline of 20% compared to the prior year period, primarily due to the negative impact of foreign currency translation. International sales declined 6% in constant currency.

3

International Division operating income was $2 million, or 0.3% of sales, in the second quarter of 2015 compared to an operating loss of $2 million, or 0.2% of sales, in the second quarter of 2014. The improvement from the prior year quarter reflected lower selling, general and administrative expenses including payroll and advertising, and improvement in the gross margin rate; partially offset by the negative flow-through impact of lower sales.

At the end of the second quarter of 2015, there were a total of 267 retail stores in the International Division, including 146 company-owned stores and 121 stores operated by franchisees and licensees.

Corporate Results

Corporate includes support staff services and certain other expenses that are not allocated to the three divisions. Unallocated operating costs were $34 million in the second quarter of 2015 compared to $33 million in the second quarter of 2014.

Balance Sheet and Cash Flow

As of June 27, 2015, Office Depot had $867 million in cash and cash equivalents and approximately $1.2 billion available under the Amended and Restated Credit Agreement, for total available liquidity of approximately $2.0 billion. Total debt was $707 million, excluding $829 million of non-recourse debt related to the credit-enhanced timber installment notes. In the second quarter of 2015, cash used in operating activities was $90 million, and included payments related to merger and acquisition expenses, legal settlements, and international restructuring expenses. Capital expenditures were $44 million in the second quarter of 2015, including $25 million related to merger integration.

Acquisition by Staples

On February 4, 2015, Office Depot and Staples announced that the companies entered into a definitive agreement under which Staples will acquire all of the outstanding shares of Office Depot. Under the terms of the agreement, Office Depot shareholders will receive, for each Office Depot share, $7.25 in cash and 0.2188 of a share in Staples stock at closing. The transaction has been approved by both companies’ Board of Directors, and was overwhelmingly approved by Office Depot shareholders at the Annual Meeting on June 19, 2015, with 99.5% of votes cast in favor of the transaction. Also In the second quarter, the proposed transaction received clearance from the Commerce Commission of New Zealand and the Ministry of Commerce of the People’s Republic of China. Office Depot and Staples continue to seek clearance from regulatory agencies in the United States, the European Union, Canada, and Australia. The agreement includes representations, warranties and conditions, including breakup fees under certain conditions if the transaction fails to close. The transaction is anticipated to close by the end of 2015. Refer to the company’s definitive proxy statement/prospectus filed with the Securities and Exchange Commission on May 18, 2015 for additional information on the transaction.

Outlook

Office Depot continues to expect total company sales in 2015 to be lower than 2014, primarily due to its decision to close certain stores, the negative impact of currency translation, business disruption from the announcement of the pending acquisition by Staples, and continued challenging market conditions in our industry.

In 2015, total company capital expenditures are expected to be approximately $200 million, and total company depreciation and amortization is expected to be approximately $300 million.

With respect to the OfficeMax merger:

Also, the company expects the European restructuring plan to generate annualized cost reduction benefits of approximately $80 million by the end of 2016, based on current exchange rates (no change to the original estimated benefit in local currencies that was initially communicated in October 2014). Restructuring charges are expected to be approximately $80 million in 2015, consisting of severance pay and other employee termination benefits as well as lease obligation and other costs.

Additionally, the company estimates it will incur approximately $100 million of expenses related to the pending acquisition by Staples, primarily consisting of employee retention costs and advisory fees, $49 million of which were incurred in the first half of 2015.
