About State Street

State Street Corporation is a financial holding company organized in 1969 under the laws of the Commonwealth of Massachusetts. State Street provides financial and managerial support to our legal and operating subsidiaries. Through our subsidiaries, including our principal banking subsidiary, State Street Bank and Trust Company, we provide a broad range of financial products and services to institutional investors worldwide. We refer to State Street Bank and Trust Company as State Street Bank or the Bank.

As of December 31, 2019, we had consolidated total assets of $245.61 billion, consolidated total deposits of $181.87 billion, consolidated total shareholders’ equity of $24.43 billion and over 39,000 employees. We operate in more than 100 geographic markets worldwide, including the U.S., Canada, Europe, the Middle East and Asia.

We are a leader in providing financial services and products to meet the needs of institutional investors worldwide, with $34.36 trillion of assets under custody and/or administration and $3.12 trillion of assets under management as of December 31, 2019. Our clients include mutual funds, collective investment funds and other investment pools, corporate and public retirement plans, insurance companies, foundations, endowments and investment managers.

2019 began with significant industry challenges, including financial market weakness, falling interest rates and increased client fee pricing pressure, and our GAAP-basis revenue,pre-tax margin, diluted earnings per share (EPS) and return on average common equity (ROE) all decreased in 2019 from 2018. In the face of these headwinds, we acted aggressively to stabilize revenues and reduce expenses and made progress on key business objectives. Actions included:

Due to these actions and the steady recovery of U.S. average market levels in 2019,our financial results in the second half of the year improved relative to the first half of the year. On a GAAP basis, second half total revenue increased by approximately 3%, total fee revenue was up approximately 2% and EPS increased approximately 7% relative to the first half of the year. With regard to risk management performance, we made progress on initiatives to improve our financial risk posture, but did not achieve desired non-financial risk improvement. While we know more is required for us to advance our overall performance, we are nonetheless confident in the trajectory of our business and focused on continuing to improve our performance. The performance metrics used in our executive compensation programs are linked to the below financial results presented on anon-GAAP basis.

Overview of 2019 Executive Compensation Program

Sound Compensation and Corporate Governance Practices

State Street develops and implements a compensation program for our Named Executive Officers, or NEOs, and other executive officers, which aims to:

For each of our NEOs identified in the “Compensation Discussion and Analysis,” the Human Resources Committee, which was previously the Executive Compensation Committee, determines the appropriate level of total compensation for the year. We engage with our largest shareholders to understand their perspectives on our compensation and governance programs. For 2019, we engaged or requested engagement with shareholders representing more than half of our outstanding common stock.

The Committee evaluates individual compensation for our NEOs and other executive officers by looking at total direct compensation, consisting of base salary and incentive compensation. The Committee evaluates base salary and incentive compensation levels at least annually.

Base Salary.Base salary is a relatively small portion of total compensation for the NEOs.

Incentive Compensation Targets. The Committee establishes incentive compensation targets for our NEOs each year. The targets are based on each executive’s role and responsibilities, performance trend, competitive and market factors and internal equity.

More information about executive compensation at State Street is described under the heading “Compensation Discussion and Analysis.”

Corporate Governance at State Street

Governance Guidelines and Independence

State Street’s Board of Directors, or Board, in its role of overseeing the conduct of our business, is guided by our Corporate Governance Guidelines, or the Guidelines. Among other things, the Guidelines describe the role of the Board, its responsibilities and functions, the director qualification and selection process and the role of the Lead Director. The Guidelines also contain categorical standards for determining director independence under New York Stock Exchange, or NYSE, listing standards. In general, a director would not be independent under these standards if the director (and in certain circumstances, a member of the director’s immediate family) has, or in the past three years had, specified relationships or affiliations with State Street, its external or internal auditors or other companies that do business with State Street (including employment by State Street, receipt of a specified level of direct compensation from State Street—other than director fees—and compensation committee interlocks). The categorical standards also provide specified relationships that, by themselves, would not impair independence. The portion of the Guidelines addressing director independence is attached asAppendix A to this proxy statement. The full Guidelines are available under the “Corporate Governance” section in the “For Our Investors” section of our website atwww.statestreet.com. In addition to the Guidelines, the charters for each principal committee of the Board are available in the same location on our website. State Street also follows the governance standards relative to the Investor Stewardship Corporate Governance Group’s (ISG) framework for U.S. listed companies. State Street’s alignment with the ISG framework is attached asAppendix B to this proxy statement.

Pursuant to the Guidelines, the Board undertook its annual review of director independence in early 2020. State Street, as a global financial institution and one of the largest providers of financial services to institutional investors, conducts business with many organizations throughout the world. Our directors or their immediate family members may have relationships or affiliations with some of these organizations. As provided in the Guidelines, the purpose of the director independence review was to determine whether any relationship or transaction was inconsistent with a determination that the director was independent. As a result of this review, the Board, after review and recommendation by the Nominating and Corporate Governance Committee, determined that all of our directors, with the exception of Mr. O’Hanley, meet the categorical standards for independence under the Guidelines, have no material relationship with State Street (other than the role of director) and satisfy the qualifications for independence under listing standards of the NYSE.

In making the independence determinations in 2020, the Board considered that the below identified individuals, or their respective family members, have the following relationships or arrangements that are deemed to be immaterial under the categorical standards for independence included in the Guidelines:

In 2019, none of these commercial or charitable relationships with affiliated entities involved amounts paid or received by State Street exceeding the greater of $1 million or 0.6% of the affiliated entity’s annual gross revenue.

Standards of Conduct

We have a Standard of Conduct for Directors, which together with the Standard of Conduct for Employees, promotes ethical conduct and the avoidance of conflicts of interest in conducting our business. We also have a Code of Ethics for Senior Financial Officers (including the Chief Executive Officer), as required by the Sarbanes-Oxley Act and SEC rules. Each of these documents is available under the “Corporate Governance” section in the “For Our Investors” section of our website atwww.statestreet.com. Only our Board may grant a waiver for directors, senior financial officers or executive officers from a provision of the Standard of Conduct for Directors, the Standard of Conduct for Employees or the Code of Ethics for Senior Financial Officers, and any waivers will be posted under the “Corporate Governance” section in the “For Our Investors” section of our website atwww.statestreet.com.

Board Composition

In connection with nominating directors for election each year and evaluating the need for new director candidates as appropriate, including skill sets, diversity, specific business background and global or international experience, the Nominating and Corporate Governance Committee, with input from the entire Board and management, focuses on the Board’s capabilities and functioning as a whole.

Annual Director Evaluations

The Nominating and Corporate Governance Committee annually assesses each director’s performance and contributions to the overall effectiveness of the Board. The Committee discusses each director and using the evaluation criteria illustrated below measures each director’s performance. Based on the results of the evaluation, the Board believes that each of the director nominees has substantial achievement in his or her personal and professional pursuits and has talents, experience, judgement and integrity that will contribute to the best interests of State Street and to long-term shareholder value. The nominees as a group possess the skill sets, specific business background and global or international experience that the Board desires. The director nominee biographies set forth in this proxy statement under the heading “Item 1—Election of Directors” indicate each nominee’s qualifications, skills, experience and attributes that led the Board to conclude he or she should serve as a director of State Street.

Annual Board and Committee Self-Evaluation

In addition, the Board and each Board committee conducts an annual self-evaluation of its performance and effectiveness. Directors complete a questionnaire evaluating the Board and each committee on which they serve, specifically focusing on areas of potential improvement. The overall performance of the Board—including its contributions to State Street—and a compilation of director responses is reviewed and discussed by the Nominating and Corporate Governance Committee and by the full Board. Similarly, the performance of each committee, along with specific committee member responses, is reviewed and discussed by the respective committee. The Nominating and Corporate Governance Committee further assesses whether each of the Examining and Audit Committee, Human Resources Committee, Nominating and Corporate Governance Committee, Risk Committee and Technology and Operations Committee has a functioning self-evaluation process and reports its findings to the Board. The Nominating and Corporate Governance Committee concluded, that for 2019, each of the respective committees had a functioning self-evaluation process.

Director Identification and Selection Process

The Board regularly reviews its composition and size to evaluate its overall effectiveness and alignment with Company strategy. As part of this review, the Nominating and Corporate Governance Committee, in conjunction with the Board, establishes the desired criteria, skills and areas of expertise needed to continue to support the Board in advancing the Company’s businesses and strategy. Once the desired characteristics are established, the Committee reviews each director candidate. Illustrated below is an overview of the process used to identify the desired attributes and to select new candidates for the Board.

Ms. Marie Chandoha is a first-time nominee for election as a director by shareholders at the 2020 annual meeting. Ms. Chandoha was first identified by a third-party search firm that was retained to identify potential director candidates. At the request of the Nominating and Corporate Governance Committee, the search firm first discussed with the members of the Committee the priority characteristics of a new director candidate, in light of the preferred individual and Board qualities discussed above. The search firm provided the Committee a list of candidates who were interested in State Street and who met the selection criteria, experience and characteristics, and the Chairman of the Board, Chair of the Nominating and Corporate Governance Committee and select members of the Committee and Board personally conducted interviews. The Board is nominating Ms. Chandoha as she meets several of the criteria identified by the Board for new directors, including Ms. Chanodha’s extensive leadership experience in the financial services industry and track record of transforming businesses. Both the Nominating and Corporate Governance Committee and the Board of Directors believes that Ms. Chandoha has the background and requisite experience to make significant contributions on many levels to State Street through her continued service as a director. Ms. Chandoha was deemed independent by the Board under the Corporate Governance Guidelines.

In carrying out its responsibility to identify the best qualified candidates for directors, the Nominating and Corporate Governance Committee will consider proposals for nominees from a number of sources, including recommendations from shareholders submitted upon written notice to the Chair of the Nominating and Corporate Governance Committee, c/o the Office of the Secretary of State Street Corporation, One Lincoln Street, Boston, Massachusetts 02111 (facsimile number(617) 664-8209). The Committee seeks to identify individuals qualified to become directors, consistent with the identified criteria.

By following the procedures set forth under “General Information About the Annual Meeting—Proposals and Nominations by Shareholders,” shareholders also have the right under ourby-laws to directly nominate director candidates and, in certain circumstances, to have their nominees included in State Street’s proxy statement.

Director Nominee Qualifications, Diversity and Skills

We believe that our Board of Directors should have a variety of qualifications, skill sets and experience that, when taken as a whole, best serve the Company and our shareholders. We recognize the importance of diversity with regard to the composition of the Board and strive to have a Board that provides diversity of thought and a broad range of perspectives. In an effort to achieve these objectives, the Nominating and Corporate Governance Committee and the Board consider a wide range of attributes when determining and assessing director nominees and new candidates, including personal and professional backgrounds, gender, race, national origin and tenure of Board service. The Nominating and Corporate Governance Committee is committed to considering diversity in its director candidate recommendations. The Committee does not assign specific weight to the various factors it considers and no particular criterion is a prerequisite for nomination. As summarized below, each of our directors brings to the Board a variety of qualifications and skills and, collectively, these qualifications form a depth of broad and diverse experiences that help the Board effectively oversee our activities and operations.

Board Leadership Structure

Leadership Transition

During the past year, the Company completed its leadership transition. On January 1, 2019, Ronald P. O’Hanley assumed the role of Chief Executive Officer and effective January 1, 2020, he was appointed as Chairman of the Board. In addition to serving as Chairman and Chief Executive Officer, Mr. O’Hanley has served as President since November 2017.

Board Governance

State Street’s leadership structure includes an independent Lead Director of the Board. This position is currently held by Amelia C. Fawcett. Dame Amelia was elected Lead Director in May 2019 for a term that expires in May 2020.

As Chairman, Mr. O’Hanley presides at all meetings of the Board of Directors during which he is present and he works with the independent Lead Director to establish the agendas for these meetings and matters on which the Board will vote.

Board Leadership Review Process

The Nominating and Corporate Governance Committee coordinates the annual independent Lead Director nomination and election process. In addition, the Board of Directors reviews the Board leadership structure at least annually to assess and determine the appropriate structure for the Company. The Board values the flexibility to permit frequent review and determination of the appropriate leadership structure based on the opportunities and circumstances of the Company at any given time.

After the independent directors’ review and assessment, the Board of Directors believes that Mr. O’Hanley’s role as Chairman, together with a strong independent Lead Director, is currently the most effective leadership structure for State Street and is in the best interests of the Board, State Street and its shareholders.

Among the factors considered by the Board in determining that the current leadership structure is the most appropriate are:

Communication with the Board of Directors

Shareholders and interested parties who wish to contact the Board of Directors or the Lead Director should address correspondence to the Lead Director in care of the Secretary. The Secretary will review and forward correspondence to the Lead Director or appropriate person or persons for response.

An interested party who wishes to contact the Lead Director may use any of the following methods, which are also described on State Street’s website atwww.statestreet.com:

The Lead Director may forward to the Examining and Audit Committee, or to another appropriate group or department, for appropriate review, any concerns the Lead Director receives. The Lead Director periodically reports to the independent directors as a group regarding concerns received.

Meetings of the Board of Directors and Annual Meeting of Shareholders Meeting

During 2018,2019, the Board of Directors held 8 meetings, and each of the incumbent directors attended at least 75 percent of the total of all meetings of the Board and committees on whichfor such period as the director served. Although State Street does not have a formal policy regarding attendance of directors at the annual meeting of shareholders, all directors are encouraged to attend. Each of the 12 directors on the Board at the time of our 20182019 annual meeting of shareholders attended the meeting.

The Committee did not treat peer group data as definitive when determiningnon-employee director compensation. Rather, it referenced peer group compensation as well as trends in director compensation generally and within the industry and formed its own perspective on compensation for ournon-employee directors. In 2018,2019, the Committee made its recommendation to the Board, which, following the May 20182019 annual meeting of shareholders, approved director compensation for allnon-employee directors effective through the 20192020 annual meeting of shareholders.

Mr. Hooley is the onlyO’Hanley, as an employee director, who was also one of our employees during 2018, and the determination of his compensation for his service as our Chief Executive Officer is described under the heading “Executive Compensation—Compensation Discussion

STATE STREET CORPORATION    11

Director Stock Ownership Guidelines

Under our stock ownership guidelines, allnon-employee directors are required to maintain a target level of stock ownership equal to 8 times the annual retainer of $90,000 for a total of $720,000.Non-employee directors must hold all net shares received until they reach the target ownership level. For purposes of these stock ownership guidelines, the value of shares owned is based on the closing price of our common stock on the NYSE on the date that we use for the beneficial ownership table below under the heading “Security Ownership of Certain Beneficial Owners and Management.”Non-employee directors are credited with all shares they beneficially own for purposes of the beneficial ownership table, which includes all shares awarded as director compensation, including share awards that have been deferred.Non-employee directors are expected to attain the ownership level ratably over a five-year period.

Our Securities Trading Policy prohibits directors from short selling State Street securities, engaging in hedging transactions in State Street securities and engaging in speculative trading of State Street securities.

As of March 5, 2019,2, 2020, Mses. DugleChandoha and Mathew and Messrs. Freda, Meaney and O’Sullivan exceeded thepro-rated expected level of ownership but are below the full target ownership level, and therefore subject to the holding requirement. Each of the othernon-employee directors exceeded the full target level of ownership under the guidelines.
