Introduction

---

What is the purpose of this proxy statement?

This proxy statement relates to Grainger's 2013 annual meeting of shareholders to be held on April 24, 2013, and any adjournment of that meeting. It contains information intended to help you make your voting decisions. We are sending the proxy statement to you because Grainger's Board of Directors is soliciting your proxy to vote your shares at the meeting. The mailing of the proxy statement and other proxy-soliciting materials to you and other shareholders began on or about March 15, 2013.

What matters are scheduled to be presented?

n

The election of eleven directors;

n

A proposal to ratify the appointment of Ernst & Young LLP as Grainger's independent auditor for the year ending December 31, 2013; and

n

A proposal to consider and hold an advisory vote on the compensation of Grainger's Named Executive Officers.

Who is entitled to vote?

Holders of shares of common stock outstanding on Grainger's books at the close of business on March 4, 2013, the record date for the meeting, may vote. There were 69,641,550 shares of common stock outstanding on that date.

If my shares are held in street name can my broker vote for me?

Unless you have given specific voting instructions to your broker, your broker cannot vote your shares on the election of directors, on the advisory vote related to executive compensation or on any non-routine matters.

What is the difference between holding shares as "shareholder of record" and as "beneficial owner"?

If your shares are registered directly in your name with Grainger's transfer agent, Computershare Trust Company, N.A., you are the shareholder of record with respect to those shares and you have the right to instruct us directly how to vote your shares or to vote in person at the meeting.

If your shares are held in street name by a brokerage firm, bank, or other nominee, you are the beneficial owner of the shares. Your nominee is required to vote your shares according to your direction. If you do not instruct your nominee how you want your shares voted, your shares cannot be voted for the election of directors or on the advisory vote on the compensation of Grainger's Named Executive Officers. Please contact your brokerage firm, bank, or other nominee with instructions to vote your shares for the election of directors and on other matters to be considered at the meeting.

How many votes do I have?

You have the right to cumulative voting in the election of directors. This means that you have a number of votes in the election equal to the number of shares you own multiplied by the number of directors being elected. You can cast those votes for the nominees as you choose. For example, you may cast all your votes for one nominee or you may apportion your votes among two or more nominees.

In any matter other than the election of directors, each of your shares is entitled to one vote.

Table of Contents

Does Grainger have majority voting for election of directors?

Yes. Directors are elected by the votes of a majority of the shares represented in person or by proxy at the meeting and entitled to vote.

What voting standard applies to the ratification of the appointment of independent auditor?

Ratification of the appointment of independent auditor requires the affirmative votes of a majority of the shares represented in person or by proxy at the meeting and entitled to vote.

What voting standard applies to the advisory vote on the compensation of the Named Executive Officers?

Although the shareholders' vote is advisory and therefore non-binding, the vote on the compensation of the Named Executive Officers—Grainger's five highest paid officers whose compensation is discussed in the Compensation Discussion and Analysis—is determined by the votes of a majority of the shares represented in person or by proxy at the meeting and entitled to vote.

How frequently does Grainger conduct an advisory vote on the compensation of its Named Executive Officers?

The Board of Directors has determined to hold an advisory vote on the compensation of the Named Executive Officers at every annual meeting of shareholders.

What if I don't indicate my voting choices?

If Grainger receives your proxy in time to permit its use at the meeting, your shares will be voted in accordance with the instructions you indicate. If we have received your proxy and you have not indicated otherwise, your shares will be voted as recommended by Grainger's Board. Specifically, your shares will be voted, either individually or cumulatively:

n

FOR the election of the director nominees;

n

FOR the proposal to ratify the appointment of the independent auditor; and

n

FOR the approval of the advisory resolution on the compensation of Grainger's Named Executive Officers.

If you are a beneficial owner and the shares you own are held in street name by a brokerage firm, bank, or other nominee you must specifically instruct your nominee how you want your shares voted for the election of directors and on the advisory resolution on the compensation of Grainger's Named Executive Officers; otherwise your nominee is not allowed to vote your shares. Please contact your brokerage firm, bank, or other nominee with instructions to vote your shares for the election of directors and on other matters to be considered at the meeting.

How does discretionary voting apply?

Grainger is not aware of any matter not described in this proxy statement that will be presented for consideration at the meeting. If another matter is properly presented, your shares will be voted on the matter in accordance with the judgment of the person or persons voting the proxy unless your proxy withholds discretionary authority.

May I revoke my proxy?

Yes. You may revoke your proxy at any time before the voting at the meeting. You can do so in one of the following ways:

1.

Deliver to Grainger's Corporate Secretary timely written notice that you are revoking your proxy; or



2.

Provide to Grainger another proxy with a later date (which can be done by telephone, by Internet, or by signing, dating, and returning a proxy form); or



3.

Vote in person at the meeting.

Table of Contents

What does it mean if I receive more than one set of proxy materials?

Receiving multiple sets of proxy-soliciting materials generally means that your Grainger shares are held in different names or in different accounts. You must vote all of the proxy requests to ensure that all your shares are voted.

What constitutes a quorum at the meeting?

A majority of the outstanding shares entitled to vote on a matter, whether present in person or by proxy, constitutes a quorum for consideration of that matter at the meeting. A quorum is necessary for valid action to be taken on the matter. Your shares will be present by proxy and count toward the quorum if you give us your proxy by telephone, by Internet, or by signing, dating, and returning a proxy form.

Who pays the costs of soliciting proxies?

Grainger will pay all the costs of soliciting management proxies. Brokerage firms, custodians, nominees, fiduciaries, and other intermediaries are being asked to forward the proxy-soliciting materials to beneficial owners of Grainger common stock and to obtain their authority to give proxies. Grainger will reimburse these intermediaries for their reasonable expenses.

In addition to mailing proxy-soliciting materials, Grainger's directors, officers, and regular employees may solicit proxies personally, by telephone, or by other means. They will not receive additional compensation for these services, other than normal overtime pay, if applicable. Representatives of Grainger's transfer agent may also solicit proxies. Grainger additionally has employed D.F. King & Co., Inc. to help solicit proxies and will pay that firm approximately $7,000 for its services, plus reasonable costs and expenses.

Where can I find the voting results?

We will report the voting results on either a Form 10-Q or on a Form 8-K within four business days after the end of our annual meeting.

How do I submit a shareholder proposal or directly nominate a director at the 2014 annual meeting?

If you wish to have a shareholder proposal included in Grainger's proxy-soliciting materials for the 2014 annual meeting of shareholders, please send a notice of intent to submit your proposal at that meeting to the Corporate Secretary at Grainger's headquarters. The notice, including the text of the proposal, must be in writing, signed, and in compliance with the timing and other requirements of the proxy rules of the Securities and Exchange Commission. For a shareholder proposal relating to the 2014 annual meeting to be timely, Grainger must receive the notice no later than November 15, 2013.

Grainger's by-laws require written notice concerning a shareholder submission of a proposal or a shareholder nomination of a person for election as a director at a meeting of shareholders. For a shareholder proposal, certain information about the shareholder and the proposal is required. For the submission of a proposal, the notice must be furnished generally not less than 90 days and not more than 120 days before the anniversary date of the prior year's annual meeting. Likewise, for a shareholder nomination, certain information about the shareholder and the nominee is required. For a nomination to be considered at Grainger's 2014 annual meeting, the notice must be furnished no later than November 15, 2013.

Recommending Candidates for Board Membership

---

The Board Affairs and Nominating Committee recommends candidates for Board membership based on a number of criteria, including ethical standards, judgment, independence and objectivity, strategic perspective, record of accomplishments, and business knowledge and experience applicable to Grainger's goals. Suggestions as to candidates are received from members of the Board Affairs and Nominating Committee, other directors, employees, search firms and others, including shareholders.

Any shareholder who would like the Board Affairs and Nominating Committee to consider a candidate for Board membership should send a letter of recommendation containing the name and address of the proposing shareholder and of the proposed candidate and setting forth the business, professional, and educational background of the proposed candidate, as well as a description of any agreement or relationship between the proposing shareholder and proposed candidate. A written consent of the proposed candidate to being identified as a nominee and to serve as a director if elected must also be provided. The communication should be sent by mail or other delivery service to the attention of the Corporate Secretary at Grainger's headquarters.

---

Director Independence

---

The Board has adopted "categorical standards" to assist it in making independence determinations of nominees. The categorical standards are intended to help the Board in determining whether certain relationships between nominees and Grainger are "material relationships" for purposes of the New York Stock Exchange (NYSE) independence standards. The categorical standards adopted by the Board have more restrictive thresholds than the NYSE's bright line revenue test for non-independence. The categorical standards adopted by the Board are set forth in Appendix A to this proxy statement and are also available in the Corporate Governance section of Grainger's website at www.grainger.com/investor.

In the ordinary course of its operations during 2012, Grainger engaged in various types of transactions with organizations with which Grainger directors are associated in their principal business occupations or otherwise. Specifically, in the ordinary course of its business during 2012, Grainger bought products and/or services from, or sold products and/or services to, companies with which Messrs. Hall, Levenick, McCarter, Santi, and Slavik are associated as executive officers or otherwise. In no instance did the total amount of the purchases from or sales to any such company during 2012 represent more than 0.190% of the projected consolidated gross revenues of that company for the year or more than 0.416% of the consolidated gross revenues of Grainger for the year.

In addition, as part of its overall 2012 charitable contributions program, Grainger made donations to tax-exempt organizations with which Messrs. Anderson, Gantz, McCarter, Novich, Roberts, and Santi serve as officers, directors or trustees. In no instance did the total amount of the contributions to such an organization during 2012 represent more than 0.098% of that organization's projected total receipts for the year.

The Board considered these transactions and donations in assessing the independence of the directors involved against the NYSE's independence standards and Grainger's categorical standards, and determined that none of the directors had any direct or material indirect interest in the transactions and donations. Similar transactions and donations are likely to occur in the future, and are not expected to impair the independence of the directors involved.

Table of Contents

The Board has determined that each of Messrs. Anderson, Gantz, who is not standing for reelection, Hall, Levenick, McCarter, Novich, Roberts, Rogers, Santi, and Slavik, and Ms. Hailey has no material relationship with Grainger within the meaning of the NYSE independence standards and Grainger's categorical standards. The other nominee, Mr. Ryan, is a Grainger employee and, accordingly, is not considered "independent." All of the nominees were previously elected by the shareholders at the 2012 annual meeting of shareholders.

---

Annual Election of Directors

---

Grainger's directors are elected each year at the annual meeting. As set forth in the Operating Principles for the Board of Directors, Grainger expects all directors and nominees to attend annual meetings. At the 2012 annual meeting, all of the directors were in attendance. In addition, all directors attended at least 75% of Board and Committee meetings.

Eleven directors have been nominated for election at this year's annual meeting of shareholders. All directors are elected for a one-year term. Each director will therefore serve until the 2014 annual meeting of shareholders or until his or her successor has been qualified and elected. Details concerning the nominees are provided below.

Majority (rather than plurality) voting applies to Grainger's director elections. Accordingly, directors are elected by the votes of a majority of the shares of Grainger common stock represented in person or by proxy at the meeting and entitled to vote. A shareholder directing to withhold authority for re-election of a director will have the same effect as votes against the election of that director. Assuming a quorum is present, broker non-votes will not affect the outcome of the vote. If any of the nominees for director mentioned below should be unavailable for election, a circumstance that is not expected, the person or persons voting your proxy may exercise discretion to vote for a substitute nominee selected by the Board.

The nominees have provided the following information about themselves, including their ages in March 2013. Each nominee has provided information on their relevant background that includes their experience for at least the past five years.

Determination Regarding Director Experience, Qualifications, Attributes, and Skills

---

Grainger's directors and nominees have varied experiences, qualifications, attributes, and skills that assist them in providing guidance and oversight to Grainger's management as it operates a multichannel business model through a network of branches, distribution centers, sales representatives, direct marketing, including catalogs, and a variety of electronic and Internet channels and with more than 22,400 employees in the United States, Canada, Europe, Asia, and Latin America. With 2012 sales of $9 billion and a leading broad-line distributor of maintenance, repair and operating supplies and other related products and services in North America with an expanding presence in Europe, Asia and Latin America, Grainger has a diverse customer base necessitating depth and breadth of product lines and offerings.

The Board has identified experience, qualifications, attributes, and skills that in light of Grainger's business and structure are relevant to service on the Board of Directors. The Board considers nominees who have demonstrated integrity and accomplishment in their business and professional careers and who possess the necessary experience, qualifications, attributes, and skills to contribute to the Board and Grainger. In addition, ongoing director education, whether provided by Grainger or by a third party, are important to service on the Board of Directors. Current nominees have engaged in continuing education and other programs to remain current in their particular areas of expertise as well as to further their understanding of corporate governance and in other matters relevant to Grainger.

The Board believes the experience, qualifications, attributes, and skills of each nominee qualify the nominee for service on the Board of Directors. Each of the current nominees has significant leadership experience in large, multifaceted organizations. This experience includes developing and executing corporate strategy, overseeing operations, and managing risks in organizations similar in size or complexity to Grainger. The summary provided below is not a comprehensive statement of each nominee's background but is provided to describe the primary other experiences, qualifications, attributes, and skills that led the Board to nominate each individual.

Mr. Brian P. Anderson served as the chief financial officer (CFO) of two public companies, held finance positions including corporate controller and vice president of audit and was an audit partner at an international public accounting firm. As a result, Mr. Anderson has in-depth knowledge of accounting and finance as well as familiarity in risk management and risk assessment and the application of the Committee of Sponsoring Organizations of the Treadway Commission internal controls framework. In addition, while serving as a CFO of one of the two public companies, Mr. Anderson had primary responsibility for the supply chain and logistics of that company. Mr. Anderson also has in-depth experience in corporate governance matters and is the Chairman of the Board of a public company as well as a member of the governance committee of two other public companies. In addition, Mr. Anderson serves on the audit committee of three public companies, including Grainger.

Board Diversity

---

One of the primary objectives of Grainger's corporate governance structure is to have a highly functional Board that properly oversees Grainger's strategies and operations. The Board's Criteria for Membership on the Board of Directors (Criteria) list the various characteristics that the Board Affairs and Nominating Committee should consider in reviewing candidates for the Board. In addition to relevant business experience, qualifications, attributes, skills, and the willingness to become involved with Grainger, the Criteria also enumerate personal characteristics that should be considered, including reputation for ethics and integrity, common sense and judgment, independent and objective thought, and the consideration of diverse opinions.

Regarding diversity, the Criteria specify that consideration shall be given to candidates without regard to race, color, religion, gender or national origin. To ensure that the Board benefits from diverse perspectives, it seeks qualified nominees from a variety of backgrounds, including candidates of gender and racial diversity, and in any retained search for Board candidates, Grainger specifies that the Board is seeking candidates with gender and racial diversity. The Board actively reviews diversity recruiting efforts.

Board of Directors and Board Committees

---

Six meetings of the Board were held in 2012. Each regular Board meeting included at least one executive session, during which only independent directors were present. In addition, the directors acted once by unanimous written consent during the year.

The Board has three standing committees: Audit, Board Affairs and Nominating, and Compensation. All members of these committees are required to be "independent" directors.

All non-employee directors have been determined to be independent. Committee memberships are shown in the following table:

Independent Directors' Committee Assignments

 

Lead Director

---

The Operating Principles for the Board of Directors and Grainger's by-laws created the leadership position of Lead Director, to be elected annually by and from the Board's independent directors. Mr. Brian P. Anderson was elected to serve as Lead Director after the April 2012 annual meeting of shareholders.

Audit Committee

---

The Audit Committee met five times in 2012. The Board has determined that each of the members of the Audit Committee is "independent," as that term is defined in the independence requirements for audit committee members contained in the applicable rules of the Securities and Exchange Commission (SEC) and standards of the New York Stock Exchange (NYSE). The Board has also determined that each of Ms. V. Ann Hailey, Chair of the Audit Committee, Mr. Brian P. Anderson and Mr. William K. Hall, each a member of the Audit Committee, is an "audit committee financial expert," as that term is defined in the applicable rules of the SEC.

The Audit Committee assists the Board in its oversight responsibility with respect to Grainger's financial reporting process, Grainger's systems of internal accounting and financial controls, the integrity of Grainger's financial statements, Grainger's compliance with legal and regulatory requirements, the qualifications and independence of Grainger's independent auditor, and the performance of Grainger's internal audit function and independent auditor. It also has oversight responsibilities for various aspects of certain employee benefit plans. Additionally included among the responsibilities of the Audit Committee are the appointment, compensation, retention, and oversight of the independent auditor; the establishment of procedures for the treatment of complaints regarding accounting, internal accounting controls, and auditing matters; and the pre-approval of audit and non-audit services to be provided by the independent auditor. The Audit Committee has the further responsibility to review Grainger's risk assessment and risk management process and policies and to oversee compliance with Grainger's Business Conduct Guidelines.

Board Affairs and Nominating Committee

---

The Board Affairs and Nominating Committee met five times in 2012. The Board has determined that each of the members of the Board Affairs and Nominating Committee is "independent," as that term is defined in the independence requirements for members of nominating committees contained in the applicable standards of the NYSE.

The Board Affairs and Nominating Committee makes recommendations to the Board regarding the makeup of the Board and its committees, establishes specific criteria by which potential directors shall be qualified, identifies potential nominees, makes recommendations concerning director and nominee independence, reviews transactions between Grainger and related persons (as further discussed below) as well as evaluates the overall performance of the Board. It also has primary oversight responsibility for corporate governance, including the responsibility to recommend corporate governance principles, recommend Board committee responsibilities and members, evaluate the Board in the area of corporate governance, including the adequacy of the information supplied to the Board and the Board's performance of its oversight responsibilities relative to the management of Grainger, and to recommend retirement, compensation, and other policies applicable to directors; and oversight responsibility of corporate citizenship activities to advance the interest of shareholders including involvement in the communities Grainger serves and promotion of a sustainable environment. Additional responsibilities of the Board Affairs and Nominating Committee are to review senior management organization and succession and to make initial assessments regarding major issues or proposals.

Compensation Committee

---

The Compensation Committee oversees Grainger's compensation and benefits policies and programs (generally with regard to all employees and specifically with regard to officers), makes executive compensation decisions, and reviews and makes recommendations concerning other compensation related matters to be submitted to the Board and/or shareholders for approval. The general responsibilities of the Committee are to oversee:

n

That a market competitive compensation structure is in place that will attract, motivate, develop, and retain key talent necessary to help deliver performance that will increase shareholder value;

n

That compensation, especially senior management compensation, is linked to both personal and Company performance;

n

That the Company's competitive policies and practices for all employees are designed to avoid inappropriate risk taking incentives;

n

That compensation and benefit policies and practices reflect the highest level of integrity; and

n

That various stock and incentive plans are appropriately administered.

In 2012, the Compensation Committee met five times and each meeting included an executive session without management present. The Board has determined that each of the members of the Compensation Committee is "independent," as that term is defined in the independence requirements for members of compensation committees contained in the applicable standards of the NYSE.

The Compensation Committee annually reviews and approves corporate goals and objectives relevant to CEO compensation, evaluates CEO performance in light of those financial goals and objectives, and, together with the other independent directors (as directed by the Board),

2013 PROXY STATEMENT

---

determines and approves the CEO's compensation based on this evaluation, in executive session without members of management present, and approves the compensation paid to the five most highly compensated executives, the Named Executive Officers (NEOs).

In overseeing the Company's compensation programs, the Compensation Committee (the Committee) develops programs based on its own deliberations. It also considers alternatives and recommendations from its own independent compensation consultant, a variety of other compensation and benefits consultants, and management. Since 2004, the Committee has retained Deloitte Consulting LLP (Deloitte Consulting) as its independent compensation consultant. In 2013, after a review of the factors prescribed by the SEC and the NYSE, the Compensation Committee determined that its compensation consultant, Deloitte Consulting, is an independent advisor under the rules and regulations.

The independent compensation consultant is solely hired by and reports directly to the Committee. The Committee's practice is to routinely meet with the independent compensation consultant in executive session, without management present, following each Compensation Committee meeting. The Committee has sole authority to retain and terminate the independent compensation consultant, including sole authority to approve the consultant's fees. At the Committee's direction, the independent compensation consultant:

n

attends Committee meetings;

n

assists the Committee in evaluating compensation proposals;

n

helps analyze recommendations proposed by management;

n

assists with the design of the structure and metrics for incentive compensation programs;

n

responds to specific compensation-related inquiries, such as determining comparator companies used for compensation studies;

n

conducts risk reviews of the Company's performance and incentive-based compensation programs; and

n

undertakes special projects.

The Committee seeks advice from the independent compensation consultant on compensation trends and best practices, as well as in reviewing the Company's programs and policies to ensure they are designed and operate to achieve their purposes and goals. During 2012, the independent compensation consultant performed a number of specific projects, including assisting the Company in performing a risk review of the incentive programs, providing advice on executive compensation trends, and attending all Compensation Committee meetings and executive sessions.

Members of management (including certain of its NEOs) assist the Compensation Committee in performing its responsibilities by providing recommendations for the design of Grainger's compensation program for its NEOs, other officers, and other employees. Management also recommends salary and award levels, except those related to Mr. Ryan, Chairman of the Board, President and Chief Executive Officer. Mr. Ryan's salary and awards are reviewed by the Compensation Committee, either alone or together with the other independent directors (as directed by the Board), in executive session without members of management present.

The Compensation Committee grants equity awards (stock options, restricted stock units (RSUs), and performance shares) to officers and other employees under the 2010 Incentive Plan. The Committee delegates to management a limited authority to grant stock options and RSUs to non-officer employees. Awards under this authority are granted under the terms and conditions that have been approved by the Committee. The pool of shares available to management under this delegation is refreshed annually to 20,000 stock options and 25,000 RSUs. The maximum amount that management is authorized to award is 5,000 stock options

and 2,500 RSUs, and to avoid any perception of manipulated timing, all awards are effective the first business day of the month following the award. Information concerning the grants is shared with the Committee at its next meeting. The Committee may terminate this delegation of authority at its discretion.

---

Leadership Structure

---

The Board has carefully considered its leadership structure and believes that a combined Chairman/Chief Executive Officer position represents the best leadership structure for Grainger.

The Board has strong governance structures and processes in place to ensure the independence of the Board. These established structures and processes, which are reflected in the Operating Principles for the Board of Directors and the various committee charters, provide for the independent directors to exercise authority so that the Board is effective in overseeing critical matters of strategy, operations, and reporting. Important duties performed by the independent directors, either collectively or through committees made up solely of independent directors, are selecting the Chairman and Chief Executive Officer and evaluating his or her performance and the resulting compensation.

The Board believes that a single individual serving in the combined position of Chairman and Chief Executive Officer provides a useful and effective connection between the Board and Company management to help them act with a common understanding and purpose. This structure assists in the timely flow of relevant information that supports effective Board decision-making.

The Board does not believe that separating the role of the Chairman and Chief Executive Officer would result in strengthening Grainger's corporate governance or in creating or enhancing long-term value for our shareholders. While the Board generally believes that splitting the positions is unnecessary and not in the best interest of shareholders, in 2008, as part of a planned leadership succession process, it temporarily separated the two positions. The separation of these functions helped promote an orderly transition in Company leadership. At the end of the transition period, after consideration of Grainger's governance structures, the Board determined it was appropriate to recombine the Chairman and Chief Executive Officer positions.

In deciding that a combined Chairman and Chief Executive Officer position is the appropriate leadership structure for Grainger, the Board also recognized the need for independent leadership and oversight. Since 1995, Grainger's Operating Principles for the Board of Directors have assigned a leadership role to the independent director serving as Chairman of the Board Affairs and Nominating Committee. Over time, this director has been responsible for facilitating Board involvement on major issues and/or proposals, reviewing meeting agenda and information to be provided to the Board, consulting with directors, the Chief Executive Officer, and management and presiding at executive sessions of the Board.

In 2010, the Board revised its Operating Principles and by-laws to create the leadership position of Lead Director, to be elected annually by and from the Board's independent directors. Among the duties assigned to the Lead Director is the responsibility for:

n

Presiding at meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors;

n

Serving as the primary liaison between the Chairman and the independent directors;

n

Reviewing and approving the types of information sent to the Board;

2013 PROXY STATEMENT

W.W. GRAINGER, INC.

15

   

---

n

Reviewing and approving meeting agenda for the Board to ensure that critical issues are included;

n

Reviewing and approving meeting schedules to ensure that there is sufficient time for discussion of all agenda items;

n

Conducting the Board's annual self-evaluation, including coordinating Board committee evaluations;

n

Leading the Chairman/Chief Executive Officer evaluation and communicating to the Chairman/Chief Executive Officer the independent directors' annual evaluation of the Chairman/Chief Executive Officer's performance; and

n

Calling meetings of the independent directors if appropriate.

The Board believes that given Grainger's corporate governance structures and processes, a combined Chairman and Chief Executive Officer position in conjunction with an independent Lead Director provides effective oversight of management by the Board and results in a high level of management accountability to shareholders.

Board's Role in Risk Oversight

---

Grainger is a broad-line distributor of maintenance, repair and operating supplies and other related products and services serving businesses and institutions, providing customers with access to more than 950,000 products.

Director Compensation

---

Grainger's eleven independent directors each receive an annual cash retainer of $85,000 and an annual deferred stock grant of $115,000. Directors serving as Committee Chairs receive an additional annual retainer.

Grainger's eleven independent directors (directors) are compensated at a level that approximates median market practice. For 2012, Grainger paid these directors an annual cash retainer of $85,000 each for the year upon election at the annual meeting of shareholders, which covered all regularly scheduled meetings of the Board and its committees. If additional meetings were held, a per-meeting fee of $1,500 was paid to each attending director. The Chairs of Board committees and the Lead Director received additional annual retainers. For the Chair of the Audit Committee, the retainer was $20,000; for the Chair of the Compensation Committee, the retainer was $15,000; for the Chair of the Board Affairs and Nominating Committee, the retainer was $7,500; and for the Lead Director, the retainer was $7,500.

All independent directors also receive an annual deferred stock unit grant. The number of shares covered by each grant is equal to $115,000 (based on the 200-day average stock price as of January 31, in the year of the grant, a methodology consistent with the calculation used for equity awards to Grainger executives), rounded up to the next ten-share increment. The deferred stock units are settled in shares upon termination of service as a director. Directors may also defer their annual retainers, committee chair retainers, and meeting fees in a deferred stock unit account.

In benchmarking director pay, Grainger uses the same compensation comparator group that is used to benchmark compensation for Grainger's executives as described in the Compensation Discussion and Analysis. The Compensation Committee's independent compensation consultant periodically reviews the comparative information and advises on director compensation.

After the 2013 annual meeting of shareholders, the directors' compensation will be adjusted as follows:

n

The annual cash retainer for each director will remain unchanged at $85,000;

n

The deferred stock grant will increase by $10,000 to $125,000;

n

Chair Retainers:

–  Audit Committee—the annual retainer will remain unchanged at $20,000;

–  Compensation Committee—the annual retainer will remain unchanged at $15,000; and

–  Board Affairs and Nominating Committee—the annual retainer will increase by $2,500 to $10,000.

n

The annual retainer for the Lead Director will increase by $12,500 to $20,000.

Stock ownership guidelines applicable to non-employee directors were established in 1998. These guidelines provide that within five years after election, a director must own Grainger common stock and common stock equivalents having a value of at least five times the annual cash retainer fee for serving on the Board. The policy also states that any pledged shares cannot be used to meet the ownership guidelines. All directors are currently in compliance with the guidelines.

Ownership of Grainger Stock

---

The table below shows how many shares of Grainger common stock the directors, certain executive officers, and all directors and executive officers as a group beneficially owned as of March 4, 2013.

Beneficial ownership is a term broadly defined by the SEC. In general, a person beneficially owns securities if the person, alone or with another, has voting power or investment power (the power to sell) over the securities. Being able to acquire either voting or investment power within 60 days, such as by exercising stock options, also results in beneficial ownership of securities. Unless otherwise indicated in the footnotes following the table, each of the named persons had sole voting and investment power with respect to the indicated number of Grainger shares.

Section 16(a) Beneficial Ownership Reporting Compliance

---

Section 16(a) of the Securities Exchange Act of 1934 requires that Grainger's directors, executive officers, and 10% shareholders file with the SEC reports concerning their ownership, and changes in their ownership, of Grainger equity securities. Based on a review of copies of the reports provided to Grainger and representations of those persons, Grainger believes that these filing requirements were met during 2012, except that Ronald L. Jadin filed a late Form 5 disclosing two gifts which occurred in December 2011.

Report of the Audit Committee of the Board

---

The Audit Committee of the Board of Directors assists the Board in fulfilling its oversight responsibilities. The Board has determined that each of the members of the Audit Committee is "independent," as that term is defined in the independence requirements for audit committee members contained in the applicable rules of the Securities and Exchange Commission and standards of the New York Stock Exchange. The Audit Committee acts under a charter that is reviewed annually, was last amended by the Board on October 26, 2010, and is available on the Company's web site at www.grainger.com/investor.

Management is responsible for the Company's internal controls and the financial reporting process and for compliance with applicable laws and regulations. Ernst & Young LLP, the Company's independent auditor, was responsible for performing an independent audit of the Company's most recent consolidated financial statements and expressing an opinion on the conformity of those financial statements with accounting principles generally accepted in the United States of America, as well as expressing an opinion on the effectiveness of the Company's internal control over financial reporting. The Audit Committee's responsibility is to monitor and oversee these processes.

In performing these responsibilities, the Audit Committee reviewed and discussed the Company's audited consolidated financial statements and the effectiveness of internal control over financial reporting with management and Ernst & Young LLP. The Audit Committee discussed with Ernst & Young LLP matters required to be discussed under Statement on Auditing Standards No. 61, "Communication with Audit Committees", as amended and as adopted by the Public Company Accounting Oversight Board in Rule 3200T. Ernst & Young LLP also provided to the Audit Committee the letter and written disclosures required by the Ethics and Independence Rule No. 3526, "Communications with Audit Committees Concerning Independence," and the Audit Committee discussed with Ernst & Young LLP the matter of the firm's independence.

Based on the review and discussions described above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012, as filed with the Securities and Exchange Commission.

Fees for Independent Compensation Consultant

---

The Compensation Committee of the Board has engaged Deloitte Consulting LLP (Deloitte Consulting) as its independent compensation consultant. The following table sets forth the fees for services rendered by Deloitte Consulting and its affiliates with respect to fiscal year 2012:

Executive Compensation Consulting Fees: Consists of fees billed for services provided to advise the Compensation Committee of the Board with respect to executive and director compensation.

All Other Consulting Fees: Consists of fees billed for all other services provided to Grainger. None of these fees are related to compensation matters.

Since 2003, affiliates of Deloitte Consulting have provided other services to Grainger that are unrelated to executive compensation matters. The decision to engage an affiliate of Deloitte Consulting for these other services was made by management. The Board has been informed of this ongoing work and the use of an affiliate of Deloitte Consulting but neither the Board nor the Compensation Committee specifically approved these services. In 2013, after a review of the factors prescribed by the Securities and Exchange Commission and the New York Stock Exchange, the Compensation Committee determined that its compensation consultant, Deloitte Consulting, is an independent advisor under the rules and regulations.

1.     Executive Summary

The Company's compensation program is based upon a philosophy that is applied to all Company employees—to attract and retain the best people and provide them appropriate performance-based incentives that encourage them to achieve results that create long-term shareholder value.

The overall structure is designed to drive profitable growth leading to shareholder value creation. The Company made relatively few changes to its compensation programs in 2012:

n

The Company implemented a prohibition on future pledging of shares by Named Executive Officers and directors and revised the stock ownership guidelines to confirm that pledged shares do not count toward satisfying stock ownership requirements;

n

The comparator group was updated in 2012 to ensure that the Company was approximately at the median of the group in sales and enterprise value;

n

The annual incentive targets for all named executive officers except the Chief Executive Officer were increased by 5% to match median market practice; and

n

Beginning in 2013, the performance share program will focus on sales in the third year and continue to focus on Return on Invested Capital (ROIC) over three years (versus the current focus on sales in the second year).

Employees at all levels of the Company, including its executives, are provided incentives to grow the business (Sales Growth) while achieving investment returns (Return on Invested Capital, or ROIC) for the Company's shareholders. For executives, the compensation program is designed to link pay to performance and is structured to reward both annual and long-term Company performance while not encouraging excessive risk taking.

This Compensation Discussion and Analysis (CD&A) describes the Company's compensation philosophy and programs generally, and explains the compensation paid to the five most highly compensated executives—the Named Executive Officers (NEOs).

Named Executive Officers (NEOs) for 2012

Compensation includes a combination of base salary, short-term incentives, long-term equity incentives including performance shares and stock options, and a performance-based retirement vehicle. These components are combined to provide Company executives with appropriate incentives for profitable long-term growth.

The Company makes use of the following components for NEO compensation:

In order to protect shareholders' interests, the Company has the following risk mitigating procedures in place:

Target total compensation for the Company's employees and executives is generally set to approximate the market median. However, individual compensation components vary because levels of performance-based long-term compensation—which aligns management to shareholders—increase with greater levels of responsibility within the Company. NEO compensation is structured so that the largest component is long-term equity (stock options and performance shares), followed by base salary and the performance-based annual incentives (this detail is shown in the following table). Each NEO's compensation is compared to equivalent positions in a comparator group selected by the Board's Compensation Committee (with assistance from the independent compensation consultant).

The Company's compensation is structured to align a substantial portion of NEO pay to the performance of the Company and the use of performance-based pay is slightly higher than the mix seen in the comparator group of companies. The table below shows NEO compensation components as a percentage of the total target compensation package.

"Performance Based Compensation" consists of the annual incentive plan, long-term incentives and the Profit Sharing Trust (PST).

"Fixed/Individual Based Compensation" consists of base salary.

"Annual Compensation" consists of base salary and the annual incentive plan.

"Long-term Compensation" consists of stock options, performance shares, and the PST. Annual PST contributions are based on short-term performance shares and grows over time, distributions are restricted, and full vesting occurs after six years of service, making this component a long-term benefit.

"Target Market" was determined from the comparator group in the 2012 Aon Hewitt compensation study.

2012 Performance

The Company believes that revenue growth coupled with a focus on ROIC leads to shareholder value creation. Therefore, the two metrics used to determine performance-based compensation are year over year sales growth and ROIC. In 2012, Company sales were $9.0 billion (sales growth of 10.5% over 2011) and ROIC was 29.4%.

The Company is focused on profitable sales growth over the short- and long-term. Any potential risk created by using similar metrics for both short- and long-term incentive awards is mitigated by:

n

Different Performance Goals:  The short-term incentive program focuses on sales growth compared to the prior year and a pre-determined ROIC linked to the Company's one-year Plan. The long-term incentive program focuses on a specific sales dollar goal in the third year of the performance period. In addition, the program requires a threshold level of ROIC in order for the awards to vest.

n

Different Time Periods:  The short-term incentive program focuses on the achievement of sales growth and ROIC over one year. The long-term incentive program

2013 PROXY STATEMENT

Table of Contents

focuses on sales growth over three years, while maintaining profitability above 18% during the three-year period.

n

Mergers and Acquisitions (M&A):  The short-term incentive program does not include the impact of M&A for current plans. The long-term incentive program includes M&A results which are designed to encourage successful acquisitions and profitable integrations.

The Company's 2012 financial performance resulted in strong alignment between management compensation and shareholder value.

n

The annual incentive program (Management Incentive Program or MIP) achieved 81% of target.

n

Awards under the long-term 2011 Performance Share Program will be 200% of target based on 2012 sales growth, if the three year ROIC hurdle for 2011-2013 is met.

2.     Compensation Philosophy, Plans and Practices

As part of the Company's pay for performance philosophy, the Company's compensation program includes several features that maintain alignment with shareholders:

n

Emphasis on Variable Compensation.  Over 75% of the NEOs compensation is tied to Company performance which the Company believes drives shareholder value.

n

Ownership Requirements.  The CEO is required to hold equity in the Company worth at least 6x his base salary, and all other NEOs are required to hold at least 3x base salary.

n

Prohibition on Hedging and Pledging.  NEOs and directors are prohibited from hedging and future pledging of shares.

n

Clawback Provisions.  The Company has established recoupment policies for financial fraud and/or material inaccuracies for NEOs as well as recoupment for violations of non-competition agreements and non-solicitation agreements.

n

Performance Thresholds and Caps.  Both the annual incentive and performance share programs require a threshold level of performance in order to achieve any payment, and the maximum payments are capped.

n

Annual Risk Reviews.  The Company conducts an annual risk review based on a process recommended by the Compensation Committee's independent compensation consultant.

n

Minimal Perquisites.

The Company's compensation programs also maintain alignment with shareholders by not including certain features:

n

No  Excessive Change in Control Severance. The maximum cash benefit is equal to 2x salary and target bonus.

n

No  Change in Control Agreements with Excise Tax Gross-ups.

n

No  Perquisites with Tax Gross-ups.

n

No  Employment Agreements. The Company does not maintain any employment agreements with its executives.

W.W. GRAINGER, INC.

Table of Contents

n

No  Cash Buyouts, Reloads, Repricing, or Stock Options issued at a discount. Stock options issued will not be repriced, replaced, or regranted through cancellation or by lowering the stock option price of a previously granted stock option.

n

No  Payment of Dividend Equivalents on Unearned Performance Shares or Stock Options.

Overall, the Company's compensation program is designed to be straightforward and understandable to its employees and shareholders, and to drive long-term shareholder value creation by aligning compensation with both individual and Company performance.

3.     Compensation Committee of the Board

The Compensation Committee of the Board is responsible for the Company's compensation programs.

The Compensation Committee oversees the Company's compensation and benefit programs for all officers and employees. The Committee is responsible for ensuring that the Company's compensation practices reflect the highest level of integrity and that these practices protect the interests of shareholders. One of its responsibilities is to make certain that a competitive compensation structure is in place that will attract, reward, and retain employees and to motivate them to grow the business profitably. The Committee is also charged with ensuring that compensation, especially for executives, balances performance, provides appropriate incentives to increase long-term shareholder value, and ensures that compensation policies and practices for all employees do not include incentives to take inappropriate risk.

In setting individual compensation levels, the Compensation Committee (with assistance from the independent compensation consultant, Deloitte Consulting, and management) selects a compensation comparator group of companies and reviews studies of total compensation paid to executives in those companies with similar duties and responsibilities. The Committee then considers a variety of reference points, including competitive compensation data at the 25^th, 50^th, and 75^th percentiles, individual and Company performance, the executive's overall experience, replaceability, internal equity, unique skills, and management's recommendation to determine appropriate compensation for each executive. All elements of compensation are valued and reviewed in evaluating the relative competitiveness of the Company's compensation practices against the comparator group. Target total compensation for the Company's employees and executives (including the NEOs) is generally set to approximate the market median.

The Compensation Committee reviews at least annually a tally sheet for each NEO to evaluate the potential value of all compensation. The tally sheet includes each NEO's current base salary, annual incentive award, and the value of all outstanding equity-based awards (both vested and unvested), deferrals, benefits, and perquisites, as well as potential payments under termination of employment, such as retirement and certain change in control situations. Since no NEO has an employment agreement with the Company that guarantees continued employment, the tally sheets also facilitate the Committee's evaluation of the reasonableness of awards and their likely retention value.

Under its charter, the Compensation Committee both makes executive compensation decisions and recommends actions to the Board of Directors and to shareholders (for example, related to the advisory Say-on-Pay vote), as appropriate. On February 20, 2013, the Committee updated its charter to:

n

Clarify that the Committee will follow the applicable rules in determining director independence for purposes of membership on the Committee;

n

Revise the language regarding the retention of outside advisors to make it clear that the Committee has sole authority and discretion to retain, oversee and terminate advising firms, as needed; and

n

Make it clear that the Committee will consider the six factors enumerated by the New York Stock Exchange in deciding whether or not to engage an advisor.

In discharging its responsibilities, the Committee regularly consults with independent advisors, compensation consultants, and the Company's management. After a review of the factors prescribed by the Securities and Exchange Commission and the New York Stock Exchange, the Compensation Committee determined that its compensation consultant, Deloitte Consulting, is an independent advisor under the rules and regulations. The Compensation Committee's charter can be found in the Corporate Governance section of Grainger's website at www.grainger.com/investor.

4.     Risk Assessment

The Compensation Committee's oversight responsibility includes assessing the relationship between potential risk created by Company's compensation programs and their impact on long-term shareholder value. The Company's compensation programs are designed to include risk-mitigating features, and the Committee also engaged its independent compensation consultant (Deloitte Consulting) to assist with the process of an annual internal risk assessment of all incentive-based compensation, including short-term and long-term incentive programs.

The incentive compensation programs include risk-mitigating components, such as:

n

Balanced performance measures—sales growth combined with profitability;

n

Robust performance measure selection and goal setting;

n

Balanced mix of short-term and long-term incentives;

n

Balanced mix of equity vehicles—stock options are combined with performance shares;

n

Clawback provisions to recoup incentive compensation; and

n

Stock ownership requirements.

Since 2009, the Committee engaged its independent compensation consultant (Deloitte Consulting) to conduct a third-party risk assessment that would be completed every three years. For the interim years, the Company conducts an annual internal risk review based on practices and methodologies recommended by the Committee's independent compensation consultant. The results of the 2012 external risk review were discussed with the Committee and Deloitte Consulting.

Based on Deloitte Consulting's risk review and the Committee's discussions, the Committee does not believe that the Company's compensation policies and practices are reasonably likely to have a material adverse effect on the Company.

5.     Say-On-Pay

At the 2012 annual meeting of shareholders, the advisory vote to approve the compensation of the Company's NEOs received the support of over 97% of the shareholders voting on the proposal. The Compensation Committee has considered these results and believes that they confirm the appropriateness of the Company's current executive compensation policies.

6.     Role of Management

Management assists the Compensation Committee in the design, recommendation and implementation of compensation programs.

Members of management assist the Compensation Committee by routinely recommending programs that management believes will provide the appropriate level of compensation and incentives consistent with the Company's compensation philosophy. Consistent with this process, management works with advisors from Aon Hewitt to develop market information and recommends adjustments in base salaries, annual incentive targets, and long-term incentive awards to be reviewed by the Compensation Committee and approved by the Board. For officers including the NEOs other than Mr. Ryan, the recommendations also include the structure and targets of short-term and long-term incentive programs for all employees, as well as changes to programs required for regulatory compliance. These recommendations are reviewed and approved by the CEO before they are presented to the Compensation Committee. Mr. Ryan's compensation is reviewed by the Compensation Committee in conjunction with its independent compensation consultant, either alone or together with other independent directors (as directed by the Board), in executive session without members of management present.

7.     Compensation Comparator Group

The Company's compensation program is regularly benchmarked against a Compensation Committee-approved comparator group of companies that are similar to the Company in size and complexity. The Company performs these studies to understand current market practices and to provide a reference point for compensation discussions.

Every other year, the Compensation Committee (with assistance from its independent compensation consultant—Deloitte Consulting) selects a compensation comparator group of companies and undertakes a study of total compensation paid to executives occupying similar positions with similar duties and responsibilities in the comparator companies. All elements of compensation are valued and considered when determining the relative competitiveness of the Company's compensation practices. A comparator group compensation study was conducted in 2012 (2012 Compensation Study).

The current comparator group consists of 24 businesses that are relatively similar in complexity and size to the Company and represent the types of major companies with which the Company historically competes for executive talent. The companies that were selected for the 2012 Compensation Study are within a range of half of Grainger's annual revenue to a maximum of two times Grainger's annual revenue. The competitive market for executive talent includes companies both within and outside the same industry or sector as the Company. Most of the Company's publicly-traded direct competitors tend to be too small in sales or scope of operations for direct compensation comparisons with the Company. Including a broader range of companies provides a more representative depiction of the Company's competitive market for talent. Therefore, companies used for compensation comparison purposes differ from those in the industry indices used in the Company Performance Graph in Part II, Item 5 of the Company's most recent Annual Report on Form 10-K.

Management played a minimal role in selecting the 2012 compensation comparator group, as the Committee relied on Aon Hewitt for survey and market data and its independent compensation consultant (Deloitte Consulting) for assistance. The role of management in selecting the comparator group was limited to providing general comments on the relevance of each industry represented by the comparator companies.

The Compensation Committee reviews the Compensation Study in conjunction with a tally sheet listing the potential value of all compensation available for the NEOs. The Compensation Committee concluded that the earned and potential awards for 2012 were consistent with the Company's pay philosophy, Company and individual performance, and market practices. Based on this review, the Committee did not make specific adjustments to the Company's compensation programs.

8.     Base Salaries

Base salaries are intended to provide an appropriate level of fixed compensation to attract and retain executives. Base salaries are determined after a detailed evaluation of individual performance, competitive market levels, and executive experience.

Annual base salary adjustments are considered and implemented to reflect individual performance, contribution and experience, and to maintain market competitiveness. The 2012 Compensation Study showed that, on average, the Company's base salaries for NEOs were approximately at the market median (+0.3%).

Base salary increases for the NEOs, with the exception of Mr. Ryan, are reviewed and approved by the CEO before they are presented to the Compensation Committee. In approving recommendations, the Committee reviews these recommendations in conjunction with its independent compensation consultant.

The compensation awarded to Mr. Ryan is determined by the Board with assistance from the Compensation Committee and its independent compensation consultant. The Compensation Committee reviews and approves the corporate goals and objectives relevant to Mr. Ryan's compensation and evaluates his performance in light of those goals and objectives. Together with the other independent directors (as directed by the Board), the Compensation Committee determines and approves Mr. Ryan's compensation level based on this evaluation, in executive session without members of management present.

Following the annual performance management review process (which all employees participate in), base salaries are reviewed and adjusted (if appropriate) to reflect individual performance, base salaries for comparable positions from market studies, experience, tenure, and internal equity.

Based on the above mentioned process, on April 1, 2012, Mr. Ryan's base salary was increased to $1,075,000 (+8%). On January 1, 2012, the following base salary adjustments were made for the other NEOs: Mr. Jadin's base salary was increased to $570,000 (8%); Mr. Carruthers' base salary was increased to CAD 547,700 (+10%); Mr. Macpherson's base salary was increased to $539,000 (+10%.); and Mr. Pulick's base salary was increased to $539,000 (+10%). Increases included both a performance adjustment and a market adjustment to align their pay to a competitive level.

9.     Annual Incentives

Annual incentives are intended to provide an appropriate level of variable compensation to encourage executives to achieve annual results that create shareholder value without encouraging excessive risk taking.

NEOs, along with approximately 1,800 other managers, are eligible to receive short-term cash-based incentives on the achievement of specified annual Company-wide financial performance measures set forth in the Company Management Incentive Program (MIP). The Company structures the MIP to motivate performance that balances short-term and long-term results and aligns the interests of management with shareholders.

Table of Contents

Each NEO's target incentive award under the annual incentive program is based on a review of competitive market practice and is designed to approximate a market value that is generally at the median of the comparator group. The following table displays the 2012 MIP target, program and payment applicable to each NEO.

The Compensation Committee and management perform a thorough analysis in setting financial measures and goals for the Company MIP to ensure the program appropriately balances the Company's objectives, is aligned with long-term shareholder interest, and has appropriate and effective risk-mitigating components. While the measures and goals are clearly aligned with the Company's strategy, they also account for current economic conditions. The combination of sales growth and ROIC performance, as well as threshold, target, and maximum payment levels, serve to mitigate risk to the Company's shareholders.

The Company believes the design of the annual incentive program creates shareholder value and encourages performance by focusing on profitable sales growth and ROIC. The basic framework of the MIP has been in place for over ten years, although specific objectives and performance target levels have been modified on a year-by-year basis. This framework was selected to align with Company strategy and to balance sales growth with profitability, efficiency, expense management, and asset management. These measures are consistent with the Company's objective of growing profitably over time, which it believes is closely linked with shareholder value creation. The MIP framework allows the Compensation Committee the annual opportunity to adjust performance objectives in light of the current economic and competitive environment. Sales growth and ROIC remained the key structural components for the 2012 MIP. ROIC reflects how effectively management uses Company assets and is generally defined by the Company as pre-tax operating earnings divided by net working assets. Sales growth is determined by year-over-year results. Acquisitions and divestitures are not included in this determination. The total MIP payment is calculated as follows:

MIP Payment = (Sales Growth Performance + ROIC Performance)

The 2012 Company MIP was based on the Company's ROIC and year-over-year sales growth. The Company determined the payment earned for ROIC and the payment earned for sales growth, and the two amounts were added together.

For the year 2012, ROIC was 29.4% and sales growth was 10.5%, both of which were below target levels set at the beginning of the year. Based on these results, Company MIP was paid at 81%.

W.W. GRAINGER, INC.

The Company believes that it establishes the sales growth and ROIC targets to provide the appropriate level of motivation. Under the terms of the annual incentives program, the Committee has the discretion to adjust MIP payment amounts to correct for any unusual circumstances, both positive and negative, that might affect ROIC or sales growth. No discretionary adjustments were made in 2012.

Due to the nature of Mr. Pulick's role as Senior Vice President and President, Grainger International, his MIP award was based on the performance of the Company (25%) and the international business units (75%). The portion of Mr. Pulick's MIP that is based on the results of the international business units is weighted as follows: Acklands - Grainger Inc. (AGI) at 35%, China at 15%, India at 15%, International Market Development at 10%, and Latin America at 25%. The business unit programs are measured based on profitable sales growth for each corresponding business.

Table of Contents

Mr. Pulick's 2012 MIP payout was based on the objectives shown in the table below.

Incentive amounts paid to Messrs. Ryan, Jadin, Carruthers, Macpherson, and Pulick were based on the performance targets established for the 2012 MIP and were made under a separate annual incentive program described in the 2010 Incentive Plan. This program is designed to ensure that annual incentives are performance-based and fully tax deductible by the Company under Section 162(m) of the Internal Revenue Code. The previously named NEOs were designated as "Covered Employees" under the 2010 Incentive Plan, a separate shareholder-approved plan providing for, among other things, annual incentive programs funded through amounts determined by reference to the Company's reported net earnings. Under the program, the Committee allocates a portion of an incentive pool to each participant. The pool is funded with 5% of the Company's net earnings and the independent members of the Board have the authority to make specific awards. The sum of the individual participants' percentages may not be greater than 100% of the pool. The 5% funding level and predetermined incentive pool allocations were selected to provide the independent members of the Board with sufficient flexibility to calculate an appropriate level of incentive for each executive while complying with Section 162(m). The independent members of the Board may use their discretion to reduce these amounts but may not increase them. For 2012, the program created a pool of $34 million, of which only $7 million or 20% of the total pool was distributed to participants. Consistent with prior years, the independent members of

Table of Contents

the Board used their discretion to reduce the amounts to yield payments equal to those that would have made using the same financial target and measures as the 2012 MIP.

Consistent with current practices, the 2013 MIP will continue to utilize sales growth along with ROIC as performance measures. Operating earnings may be used in place of ROIC in some international business units when ROIC is not an appropriate measure.

10.  Long-Term Incentives

The Company annually provides long-term incentives to NEOs and other key managers in order to align with the following elements of the Company's strategy to improve shareholder value:

n

Achieve long-term business goals and objectives that increase shareholder value (including achieving financial performance that balances growth, profitability, and asset management);

n

Reward management for taking prudent action and achieving results that create shareholder value;

n

Attract qualified managers to join the Company; and

n

Retain management through business cycles.

The Company's long-term incentives for NEOs consist of stock options and performance shares and are provided under the shareholder-approved incentive plans. In 2012, the Company structured awards such that stock options represent approximately 70% of the total value of long-term incentive compensation and performance shares represent approximately 30% of the total value. Providing a mix of different types of equity awards is consistent market practice for senior executives. The 2012 Compensation Study suggests that the long-term compensation plans at many comparator companies use a mix of three types of equity awards—performance shares, stock options, and restricted stock units (RSUs). However, the Company believes that its mix of performance shares and stock options continues to create the strongest alignment with Company performance. The ⁷⁰/30 (stock options/performance share) mix provides an effective level of long-term performance incentive and the three year vesting schedules serve to aid in executive retention.

The target number of shares provided for stock options and performance share awards is designed to approximate an economic value that targets the median of the compensation comparator group for comparable jobs. The Compensation Committee annually establishes the target value of the award based on the executive's position. The actual award may be adjusted up or down to reflect individual performance. The value is converted to shares using the 200-day average stock price as of January 31 in the year of grant. The use of the 200-day average to calculate the number of shares is intended to smooth out stock price volatility that can distort the number of shares awarded.

NEO Long-Term Incentives

Table of Contents

Stock Options

The Company's stock options provide the right to purchase Company stock at a specified price over a ten year term. They are intended to directly link management and shareholders' interests by tying a substantial portion of management's long-term incentives to stock price appreciation. The ten year term is designed to focus the NEOs on long-term value creation. Three year cliff vesting encourages meaningful retention before an executive can realize any value created by stock price appreciation. In all cases, stock options are awarded at an exercise price equal to the closing price of the Company's common stock reported for the business day before the grant. Stock option repricing is not permitted under any of the Company's equity incentive plans.

Performance Shares

The Company's performance share program provides the NEOs and other executives with a potential share payout depending on sales growth and continued ROIC achievement over a three year cycle. The actual number of shares paid to an NEO can range from 0 to 200% of the target number of performance shares awarded. The Compensation Committee (with the assistance of its independent compensation consultant) and management perform a thorough analysis in setting the financial measures and goals for a three-year performance cycle that begins January 1 of the first year. The sales growth component is measured at the end of the cycle's third year and the ROIC component is measured at the end of the third year based on the third-year average. These measurement dates reinforce a long term focus. The combination of sales growth and ROIC performance serve to mitigate risk to the Company's shareholders, as do the threshold, target, and maximum payouts built into the program. Dividend equivalents are not paid on performance shares. Due to the three year cycle that each award covers, the Company has three performance share cycles ongoing at all times.

2010-2012 Performance Share Cycle

---

For the 2010-1012 performance share cycle, the 2011 sales target of $7.1 billion was established when 2009 sales were $6.2 billion. The Company's net sales in 2011 determined the number of shares earned, while vesting remained dependent on meeting a three year average ROIC hurdle of 18%. The payout of the target performance shares awards for this program cycle was made according to the following table:

In 2011, sales were $8.1 billion and the participants earned 200% of their target. The award vested because the Company's average ROIC for the three year period 2010-2012 was greater than 18%.

2011-2013 Performance Share Cycle

---

For the 2011-2013 performance share cycle, the 2012 sales target of $8.4 billion was established when 2010 sales were $7.2 billion. The Company's net sales in 2012 determined the number of shares earned, while vesting remains dependent on meeting a three year

Table of Contents

average ROIC hurdle of 18%. The payout of the target performance shares awards for this program cycle was made according to the following table:

In 2012, sales were $9.0 billion and the participants will receive 200% of their target if the Company's average ROIC for the three year period 2011-2013 is greater than 18%. This award will remain at risk through 2013.

2012-2014 Performance Share Cycle

---

For the 2012-2014 performance share cycle, the 2013 sales target of $10.3 billion was established when 2011 sales were $8.1 billion. The Company's net sales in 2013 will determine the number of shares earned, while vesting remains dependent on meeting a three year average ROIC hurdle of 18%. The payout of the target performance shares awards for this program cycle will be made according to the following table:

The Compensation Committee selected these performance measures because they balance sales growth with long-term profitability, expense management, and asset management and align with objectives established in the annual incentive program. The Committee may use different sales growth and ROIC objectives and targets from year to year to maximize alignment with then-current business objectives and to reflect economic conditions.

The use of stock options and performance shares satisfies the requirements for qualified performance-based compensation under Section 162(m) of the Internal Revenue Code. The Company historically makes stock option awards to current officers and employees each year on the date of the annual meeting of shareholders. Performance share awards are made no later than March 30, in order to qualify those awards as performance-based compensation under Section 162(m). The Company does not time the grant of long-term incentive awards in respect of the release of material, non-public information nor for the purpose of affecting the value of executive compensation.

In 2010 the Company added additional clawback policies related to material restatement and fraud (see the "Compensation Recoupment Policy" section for additional details). In addition and in connection with their long-term incentive awards, the NEOs and all other recipients are required to sign an agreement containing confidentiality and non-competition obligations designed to protect the Company's confidential and proprietary information and to preserve the Company's competitive advantages. Under these clawback agreements, should an executive violate his or her confidentiality or non-compete obligations, any award is automatically forfeited. The agreements also require, in certain circumstances, that an executive who has breached the confidentiality and non-compete agreements return vested shares and/or gains from disposition of shares to the Company.

11.  Stock Ownership Guidelines

As of December 31, 2012, all officers subject to stock ownership guidelines, including the NEOs, are in compliance with the guidelines.

The Company continues to believe that requiring executive ownership of Company stock creates alignment between executives and shareholders and encourages executives to act to increase shareholder value. In 1996, the Company established stock ownership guidelines for its NEOs and other officers. In 2011, the Company increased the minimum ownership requirement for the CEO from 5x base salary to 6x and established a retention ratio for equity awards. The stock ownership guidelines for the NEOs are established based upon their respective positions within the Company and are as follows:

These ownership guidelines must be met within three years of being elected an officer or assuming a new position, and are reviewed annually by the Board. Officers who fail to achieve these ownership levels will not be eligible to receive any equity-based awards until they achieve their required ownership levels. Shares owned directly by the officer (including those held as a joint tenant or as tenant in common), RSUs, shares owned in a self-directed IRA, and certain shares owned or held for the benefit of a spouse or minor children are counted toward meeting the guidelines. Stock options (whether vested or unvested) and shares underlying performance share awards before the number of shares is fixed are not counted toward meeting the ownership guidelines.

25% Retention Ratio

It is the Company's long-term goal for executives to also meet ownership requirements expressed in outright ownership of actual shares. The Company has implemented a required 25% after-tax share retention ratio for NEOs. Upon receiving shares from the Company following the exercise or settlement of equity awards, if the NEO does not hold actual shares or deferred vested shares worth the required ownership multiple, he will be required to retain 25% of the shares received from all such equity awards (net of any shares used to satisfy tax withholdings obligations).

12.  Hedging and Pledging Prohibition

The Company's Business Conduct Guidelines (which are available in the Corporate Governance section of Grainger's website at www.grainger.com/investor) prohibit employees and the Board of Directors from engaging in any financial arrangement (including, without limitation, put and call options and short sales) that establish a short position in the Company stock and are designed to hedge or offset a decrease in market value. Effective January 1, 2013, by policy, Company officers and directors are also prohibited from pledging of Company stock at any amount as collateral for a loan or for a margin account.

13.  Other Benefits

The other components of the Company's compensation program for NEOs are substantially similar to those available for most of the Company's employees. This includes the same health and welfare benefits and the same performance-based PST 21 contribution

methodology that is applied to the 19,000 U.S.-based employees who are PST participants. The Company provides Supplemental Profit Sharing Plans solely to maintain an equal percentage of PST compensation contribution to approximately 150 employees, including NEOs, who would be subject to contribution limitations imposed on qualified plans by the Internal Revenue Code. The Company does not provide any other supplemental retirement benefits to its NEOs or other employees based in the United States.

The PST is the primary Company-sponsored retirement vehicle for U.S.-based employees. The PST aligns the interests of the Company's employees, management, and shareholders as the Company's annual contribution to the PST is based on a formula that incorporates two key drivers of shareholder value—earnings performance and capital employed. The Company contributes a minimum of eight percent of payroll to the program and provides employees the opportunity to share in the success of the Company beyond this amount only if a threshold return on capital is achieved. The contribution percentage that each participating employee receives is a function of his or her years of service with the maximum contribution occurring at five or more years of service. The Company's U.S. NEOs participate in the PST on the same basis as all other employees. The Company does not maintain a defined benefit pension plan for U.S.-based employees.

Effective February 2010, the Company implemented a 401(k) plan for certain newly acquired businesses in the U.S. whose employees do not participate in the PST. Approximately 100 employees of the Company's 22,000 employees (less than 1%) are currently eligible for the 401(k) plan. None of the Company's NEOs are eligible for the 401(k) plan.

Mr. Carruthers is an employee of the Company's Canadian subsidiary, Acklands - Grainger Inc. (AGI), and therefore participates in the AGI Notional Account Plan. The AGI Notional Account Plan (for designated executives) provides a 10% contribution (of earnings above CAD 246,500), which earns an investment return equal to the Canadian prime interest rate plus 1%.

NEOs and certain other officers may elect to defer receipt of up to 50% of base salary and/or 85% of annual cash incentives under the 2004 Voluntary Salary and Incentive Deferral Plan, an unfunded deferred compensation plan. The purpose of the plan is to provide executives with retirement savings and financial planning opportunities that are not available to them in tax-qualified retirement plans due to Internal Revenue Code limitations. The investment choices and returns for their nonqualified programs are the same as those offered to all other participants in the PST.

Effective April 2011, the Company requires that the NEOs and certain other Company officers have periodic physical examinations at a facility selected by the Company. The Company believes that periodic physical exams are important to maintain the effectiveness of its executive talent.

The NEOs and certain other Company officers have grandfathered participation in the Company's former Executive Death Benefit Plan. The Company has discontinued its executive death benefit program for executives hired after December 31, 2009. Executives hired after this date are provided insurance coverage on the same basis as other employees. Unless offered to other Company employees, the Company will not make payments, grants, or awards following the death of an executive in the form of unearned salary or unearned bonuses, accelerated vesting or the continuation in force of unvested equity grants, awards or ungranted equity, perquisites, and other payments or awards made in lieu of compensation. The beneficiary of a participant who dies while employed by the Company is generally entitled to 120 monthly payments of 50% of the participant's monthly compensation, calculated on the basis of salary and target annual incentive under the applicable cash incentive program.

NEOs were eligible to be reimbursed for up to $10,000 in financial services in 2012. The financial service reimbursements are fully taxable and not grossed-up to cover taxes. Officers are allowed the business use of corporate aircraft and car and driver, while Mr. Ryan is also allowed personal use of both, subject to his reimbursement of the incremental cost of use. These benefits represent a cost-effective method of allowing the Company's top executives to more effectively use their time. In 2012, Mr. Ryan did not utilize the corporate aircraft for personal use and he reimbursed the Company for all personal use of the car and driver. All other benefits, including the PST contribution percentages and various welfare benefits provided to U.S. NEOs and other executive officers, are comparable to those provided to the majority of salaried and hourly U.S.-based Company employees.

Mr. Carruthers receives a competitive Canadian benefits package, which includes benefits over and above those offered to regular Canadian AGI employees. These benefits include Group Life Insurance, Accidental Death & Dismemberment Insurance, Dependent Life Insurance, Dental Insurance, extended Health Insurance, and Annual Executive Medical Insurance.

Effective January 1, 2012, Mr. Carruthers relocated to the United States to assume his new responsibilities as Senior Vice President and President, Grainger U.S. In addition to the relocation benefits generally made available to employees on international assignments, Mr. Carruthers receives supplemental benefits commensurate with his level. These include:

n

A housing allowance of $95,000 per year;

n

Support for automobile expenses with a cap of $40,000 per year and a one-time reimbursement up to $10,000 for loss-on-sale automobile protection; and

n

A one-time relocation allowance of 2.0x monthly base salary.

14.  Employment Contracts, Change in Control Arrangements, and Termination of Employment Arrangements

The Company does not maintain any employment agreements with its executives.

Change in Control Agreements

The Company has Change in Control Agreements (CIC Agreements) with a number of executives. These CIC Agreements are intended to ensure that in the event of a pending or threatened change in control of the Company the Company retains its management and that their full attention is focused on the best interests of the Company and its shareholders and not on the uncertainty of their future employment prospects under those circumstances.

n

The Company's CIC Agreements are "double-trigger" arrangements that require both a change in control of the Company and within the following two-year period: (a) the Company terminates the executive's employment other than for cause, or (b) the termination of the executive's employment for good reason (for example, because the Company reduced the executive's authority or aggregate benefits). Under each CIC Agreement, the executive is entitled to certain benefits which include a lump-sum payment generally equal to 2x the sum of (i) the executive's annual salary, (ii) the executive's target annual incentive, and (iii) in connection with the Company's non-contributory profit sharing plans, a percentage of annual salary and annual incentive equal to the average percentage of covered compensation contributed by the Company under the plans for the last three fiscal years. The executive is also entitled to two years of continued health and dental benefits.

n

Only certain executives will be eligible for future CIC Agreements (approximately 10 executives). Existing agreements will remain in place.

Change in Control—Equity Plans

Under the terms of the Company's 1990 Long-Term Incentive Plan, 2001 Long-Term Incentive Plan, 2005 Incentive Plan, 2010 Incentive Plan, and Director Stock Plan, as amended (Plans), a change in control generally results in the following:

n

Accelerated vesting of any unexercised stock options, whether or not exercisable on the date of such change in control;

n

Accelerated vesting of unvested RSU awards; and

n

Settlement of performance share awards in common stock equal to 100 percent of the executive's performance share target.

Deductibility of Executive Compensation; Accounting Considerations

Section 162(m) of the Internal Revenue Code generally disallows a federal income tax deduction to a public company for compensation over $1 million per fiscal year paid to the company's chief executive officer and its four other most highly compensated executive officers serving at the end of that year. Compensation that qualifies as "performance-based" compensation is not subject to the deductibility limit. A Company objective is to attempt to maximize the deductibility of compensation under Section 162(m) to the extent doing so is reasonable and consistent with Company strategies and goals. Awards under the annual incentive plan in which the NEOs participate, gains on exercises of stock options, and shares received as the result of performance share awards are considered to be "performance-based" compensation not subject to the Section 162(m) deductibility limit. Awards of time-vested restricted stock and RSUs are not exempt from the Section 162(m) deductibility limit and all or a portion of these awards may be nondeductible when the awards vest. While the tax treatment applicable to the Company's compensation programs was taken into account in designing those programs, it was not a significant consideration.

2013 PROXY STATEMENT

Table of Contents

Upon vesting, settlement or maturity, equity awards under the 2010 Incentive Plan and predecessor plans are distributed in the form of shares of the Company's common stock. Under the Accounting Standards Codification (ASC) 718 (formerly FAS 123R), these types of awards are considered equity awards. As a result, the total amount of compensation expense to be recorded for the awards is based on the fair value of the awards on the grant date. This fair value is then recorded over the vesting period, usually three years, and is recorded to compensation expense and as an increase in paid-in capital. The amount of compensation expense is not subsequently adjusted for changes in the Company's share price, nor the actual number of shares distributed. If an equity award is forfeited, all previously recorded compensation expensed is reversed. While the accounting treatment described above was considered in the development of our long-term incentive program, it was not a material consideration.

15.  Compensation Recoupment Policy (Clawbacks)

The Company has an expanded executive compensation recoupment policy (or clawback) for equity and annual incentive payments made to officers. The Company can recover incentive compensation (cash or equity) that were awarded based on achievement of financial results that were the subject of a restatement if the officer engaged in criminal conduct or financial fraud. The policy also permits the recovery of all or a portion of any incentive compensation in the case of materially inaccurate financial statements whether or not they result in a restatement and whether or not the executive officer has engaged in wrongful conduct. In addition, should an executive violate his or her confidentiality or non-compete obligations, any award is automatically forfeited, and in certain circumstances, the executive must return vested shares and/or gains from disposition of shares to the Company. Recoveries under these provisions can extend back for three years.

This policy applies to any incentive compensation awarded or paid to an employee at a time when he or she is an officer. Subsequent changes in status, including retirement or termination of employment do not impact the Company's rights to recover compensation under this policy.

Termination

The Company does not have employment contracts and does not maintain severance programs for its executives. The executive's CIC Agreements provide the potential for a lump sum payment following a change in control. Except for a limited period of time following a change in control, the NEOs are not entitled to severance upon termination.

Retirement

The definition of retirement eligibility is the same for all U.S. employees. Under this definition, an employee is retirement-eligible upon attaining any of the following:

n

Age 60;

n

Age 55 and 20 years of service; or

n

25 years of service.

Mr. Ryan is the only NEO who is currently retirement-eligible.

The Company provides the following upon retirement:

n

Outstanding stock options become vested and executives have the right to exercise such stock options within six years from date of termination or for the remaining term of the stock option, whichever is less;

n

In the year of retirement, a fraction of the stock option award received in the year of retirement vests based on the number of months the executive worked that year;

Table of Contents

n

Settlement of performance shares occurs after the end of the performance period in common stock equal to the number of the executive's outstanding performance shares earned for the performance period multiplied by the prorated portion of the performance period completed;

n

Cash payments equal to account balances under the Profit Sharing Trust, any supplemental profit sharing program, and the 2004 Voluntary Salary and Incentive Deferral Plan will be made in installment payments for up to 15 years or in a lump-sum payment based on the election made by the executive in accordance with the terms and conditions of those plans; and

n

Reduced life insurance benefits until executive's death.

In addition to the retirement benefits listed above, NEOs may receive benefits under the Company's disability plan or payments under the Company's Executive Death Benefit Plan in the event of death or disability, as applicable.

The following tables illustrate the potential incremental payments and benefits that could be received by the NEOs upon a termination or change in control of the Company. The amounts shown below assume that such termination or change in control was effective as of December 31, 2012 and thus only includes amounts earned through such date. However, the actual amounts that would be paid out under each circumstance can only be determined at the time of separation.

Transactions with Related Persons

---

Grainger's Business Conduct Guidelines require that conflicts of interest in any form be avoided. The Board has adopted written policies and procedures, to be applied by the Board Affairs and Nominating Committee, for the review, approval, or ratification of any transactions with related persons. Those policies and procedures apply to any proposed transaction in which Grainger is a participant, the amount involved exceeds $120,000, and any director, executive officer, or significant shareholder or any immediate family member of such a person has a direct or material indirect interest. The policy requires that any such proposed transaction be reviewed by the Board Affairs and Nominating Committee to determine, among other things, the benefits of the transaction to Grainger, the availability of other sources of comparable products or services, and whether the terms of the proposed transaction are comparable to those provided to unrelated third parties.

David W. Grainger, who is the beneficial owner of approximately 6.7% of the Company's outstanding common stock, is a non-executive officer of the Company. As compensation for his services as an officer, Mr. Grainger received an annual salary of $52,000, perquisites and benefits the same as those received by other officers, and the ability to use the Company aircraft and car and driver for personal travel, subject to the requirement that he fully reimburse the Company for such use.

Proposal to Consider and Hold an Advisory Vote on the Compensation of Grainger's Named Executive Officers

---

The Company is asking its shareholders for their non-binding advisory approval of the compensation of its Named Executive Officers (Say on Pay) as disclosed in the "Compensation Discussion and Analysis" section of this proxy statement in accordance with the Securities and Exchange Commission rules.

As described in detail under "Compensation Discussion and Analysis," the Company's compensation program is based upon a philosophy that is applied to all Company employees—to attract and retain the best people and provide appropriate performance-based incentives that encourage them to achieve results that create long-term shareholder value. The Company sets target compensation for the Named Executive Officers to approximate the market median of compensation at companies of similar size and complexity. Employees at all levels of the Company, including its executives, are provided clear incentives to grow the business (Sales Growth) while achieving investment returns (Return on Invested Capital or ROIC) for the Company's shareholders. The compensation program is structured to significantly reward long-term performance while not encouraging excessive risk taking. Please read the "Compensation Discussion and Analysis" beginning on page 26 for additional details about the compensation of the Named Executive Officers.

This Say on Pay vote is intended to address the compensation of the Named Executive Officers as disclosed in the "Compensation Discussion and Analysis" section of this proxy statement as a whole rather than any specific item or amount of executive compensation.

We are asking our shareholders to vote "FOR" the following advisory resolution at the Company's 2013 annual meeting:

"Resolved, that the compensation of the Company's Named Executive Officers, as disclosed in the "Compensation Discussion and Analysis" section of this proxy statement, including the related tables, notes and narrative is hereby approved by the Company's shareholders."

This advisory vote on the compensation of the Company's Named Executive Officers is determined by the votes of a majority of the shares represented in person or by proxy at the meeting and entitled to vote. Abstentions will have the same effect as votes against the proposal. Broker non-votes will not affect the outcome of the vote.

This Say on Pay vote is advisory and non-binding on the Company, our Board of Directors and the Compensation Committee of the Board. However, the Board of Directors and the Compensation Committee of the Board, which is comprised of independent directors, expect to take into account the outcome of this Say on Pay vote when making future compensation decisions regarding the Company's Named Executive Officers.

The Board of Directors recommends a vote "FOR" the approval of the advisory resolution on the compensation of the Company's Named Executive Officers.
