Letter to Shareholders

To our Shareholders,

Continuous evolution is the hallmark of a healthy, enduring business.

At Thomson Reuters, we strive to continuously redefine what it means to be an information publisher in the 21st century. The core challenge is the same as it has always been: creating more actionable value for customers. But, as the world continues to change profoundly, so too must we change the way we deliver on that value proposition.

Customers used to pay for printed volumes of need-to-know data. They moved on to networks of information stored in databases and delivered in electronic form. Today, they pay for the right answer, delivered at the right time when they need it in their working lives. And, they want information from a source they can trust.

In 2017, we made progress on our ambition to evolve our business and become the world’s preeminent source of trusted answers for knowledge workers at the intersection of commerce and regulation. And, we did so while also returning nearly $2.0 billion to shareholders in the form of dividends and share buybacks.

Our revenues grew 2% for the year before the impact of currency. On the same basis, 2017 was the first time since 2012 that all three of our primary business units delivered positive revenue growth. In 2017, our faster growth segments, including Risk, Elektron Data Platform, Legal Software & Solutions, and Global Tax, represented over one-third of our revenue base and collectively grew 7%. We also saw our operating profit increase, along with increases in adjusted EBITDA and the related margin.

Our success was enabled in part by a disciplined focus on our customers. We launched a number of initiatives to eliminate customer pain points, simplify policies and increase the efficiency and effectiveness of our sales force, resulting in an 8% increase in our ‘ease of doing business’ score as measured by customers surveyed.

We continued to invest in growth areas and behind new products and digital capabilities to better serve customers. Ten years after the first iPhone^®, a brave new digital world powered by big data, cognitive computing and the cloud promises to change the way we live, work and interact. We have been a pioneer of digital product development for decades, and in 2017 continued to build our network of technologists and partnerships, anchored by a $100 million planned investment in a new, long-term home for our Toronto Technology Centre.

Our success in 2017 was equally fueled by our people, our culture and our values. We are working to position Thomson Reuters as the career destination of choice for top-tier professionals who want to solve interesting problems with real impact on a global stage.

We announced a best-in-class parental leave policy, bringing our North American policies more closely in line with our other global locations. The Human Rights Campaign awarded us the top rating on its Corporate Equality Index for the fifth consecutive year and we were named to the Anita Borg Institute Top Companies for Women Technologists Leadership Index for the second consecutive year.

Culture and purpose matter. Through the end of 2017, we have supported formal culture and values workshops for more than 10,000 of our managers worldwide. Also in 2017, our people performed more than 177,000 volunteer hours in their communities. And, we were proud to be one of only four Canadian firms included in Fortune’s list of Most Admired Companies, this year moving to the #1 ranked firm in our industry group.

We share our employees’ pride in working for a company that supports fair and open markets, resilient tax systems, confidence in the rule of law and the transparency and rigor of independent journalism. We are immensely proud to be part of a business whose commercial mission (and through the work of our Foundation) continues to evolve in support of a sustainable, inclusive and trustworthy future.

Our next chapter includes a transformative partnership.

Earlier this year, we announced an agreement to enter into a strategic partnership with the global investment firm Blackstone to better position our Financial & Risk business. We will maintain a substantial 45% minority stake in the new partnership. Canada Pension Plan Investment Board and an affiliate of GIC will invest alongside Blackstone as well.

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

We believe Blackstone is the best partner that we could team up with to accelerate the resurgence of Financial & Risk following a six-year, hard-fought and well-executed turnaround plan. With the support of the largest publicly-traded alternative asset management firm in the world, the new partnership should reposition the business for accelerated growth in a rapidly consolidating industry and should send a clear message to customers that with Blackstone, the business has the commitment, capacity and ability to deliver and compete.

Thomson Reuters will move forward focused on driving growth and expanding our reach to legal, tax, accounting and regulatory market professionals, building on our leading positions. Under a 30-year agreement with the new partnership, Reuters news offerings will continue to shine, operating with the same editorial independence and rigor, and with even greater commercial viability.

We plan to ramp up investment in our businesses in areas including:

Thomson Reuters prospects have never been brighter and we are well positioned to deliver long-term, sustainable value for all shareholders. This includes a commitment to maintaining a strong capital structure that provides us with significant resources and flexibility.

We sit at the intersection of commerce and regulation, ideally positioned to provide our customers with unrivalled operating systems and software-enabled workflow tools built on the back of trust, authoritative and relevant intelligence.

Thanks to the support of our customers, our colleagues and our shareholders, we have a bright future doing what we do best: combining information, technology, and human expertise to provide trusted answers.

Certain statements in the letter are forward-looking. These forward-looking statements are based on certain assumptions and reflect our current expectations. As a result, forward-looking statements are subject to a number of risks and uncertainties that could cause actual results or events to differ materially from current expectations. Some of the factors that could cause actual results to differ materially from current expectations are discussed in the “Risk Factors” section of our 2017 annual report as well as in other materials that we from time to time file with, or furnish to, the Canadian securities regulatory authorities and the U.S. Securities and Exchange Commission. There is no assurance that any forward-looking statements will materialize. You are cautioned not to place undue reliance on forward-looking statements, which reflect expectations only as of this date. Except as may be required by applicable law, we disclaim any intention or obligation to update or revise any forward-looking statements.

Notice of Annual and Special Meeting of Shareholders of Thomson Reuters Corporation

To our Shareholders,

We are pleased to invite you to attend the 2018 Thomson Reuters annual and special meeting of shareholders on Wednesday, June 6, 2018 at 12:00 p.m. (Eastern Daylight Time).

3. Appoint the auditor and authorize the directors to fix the auditor’s remuneration;

4. Approve amendments to our Articles of Amalgamation related to the Thomson Reuters Trust Principles and the Thomson Reuters Founders Share Company;

This year’s meeting will cover the following items of business:

Voting Information

Who can vote at the meeting?

If you held common shares as of 5:00 p.m. (Eastern Daylight Time) on April 16, 2018 (the record date), then you are entitled to vote at the meeting or any adjourned or postponed meeting. Each share is entitled to one vote. As of April 16, 2018, there were 711,366,932 common shares outstanding.

We also have 6,000,000 Series II preference shares outstanding, but these shares do not have voting rights at the meeting.

How many votes are required for approval?

A simple majority (more than 50%) of votes cast, in person or by proxy, is required to approve each item of business, except for the proposed amendments to our Articles of Amalgamation, which require the approval of two-thirds (more than 66.6%) of votes cast.

Woodbridge, our principal and controlling shareholder, beneficially owns approximately 63% of our outstanding common shares. Woodbridge has advised our company that it will vote to approve each item of business on the basis recommended by the board of directors.

How do I vote?

You have two choices – you can vote by proxy, or you can attend the meeting and vote in person. The voting process is different for each choice. The voting process also depends on whether you are a registered or non-registered shareholder.

You should first determine whether you are a registered or non-registered holder of our common shares. Most of our shareholders are non-registered holders.

Non-registered shareholders are sometimes referred to as “beneficial owners”.

Voting by Proxy

If it is not convenient for you to attend the meeting, you may vote by proxy on the matters to be considered at the meeting. A proxy is a document that authorizes someone else to attend the meeting and cast votes for you.

Non-registered shareholders

If you are a non-registered shareholder who receives a proxy form or voting instruction form (VIF), you should follow your intermediary’s instruction for completing the form. Holders of Depositary Interests will receive a voting form of instruction or direction from Computershare Investor Services PLC.

Registered shareholders

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 7

Voting In Person

Non-registered shareholders

You should do one of the following if you plan to attend the meeting:

Registered shareholders

You do not need to do anything except attend the meeting. Do not complete or return your proxy form, as your vote will be taken at the meeting. You should register with representatives of Computershare Trust Company of Canada when you arrive at the meeting. If you wish to vote common shares registered in the name of a legal entity, that entity must submit a properly executed proxy form to Computershare Trust Company of Canada by the proxy cut-off time which appoints you to vote the common shares on its behalf.

Can I vote my shares by filling out and returning the notice?

No. The notice sets forth the items to be voted on at the meeting, but you cannot vote by marking the notice and returning it. The notice provides instructions on how to vote.

What’s the deadline for receiving my proxy or voting instructions?

If you are a registered shareholder, your proxy or voting instructions must be received by 5:00 p.m. (Eastern Daylight Time) on Monday, June 4, 2018.

Non-registered shareholders may be subject to earlier deadlines as specified in their proxy or voting instructions.

If the meeting is adjourned or postponed, the proxy cut-off deadline will be no later than 48 hours (excluding Saturdays, Sundays and holidays) before any adjourned or postponed meeting.

How will my shares be voted if I appoint a proxyholder?

Your proxyholder must vote your shares on each matter according to your instructions if you have properly completed and returned a proxy form. If you have not specified how to vote on a particular matter, then your proxyholder can vote your shares as he or she sees fit. If you have appointed our directors named on the enclosed proxy form as your proxyholder, and you have not specified how you want your shares to be voted, your shares will be voted FOR each of the items of business described in this circular.

What happens if any amendments are properly made to the items of business to be considered or if other matters are properly brought before the meeting?

Your proxyholder will have discretionary authority to vote your shares as he or she sees fit. As of the date of this circular, management knows of no such amendment, variation or other matter expected to come before the meeting.

If I change my mind, how do I revoke my proxy or voting instructions?

Non-registered shareholders

You may revoke your proxy or voting instructions by sending written notice to your intermediary, so long as the intermediary receives your notice at least seven days before the meeting (or as otherwise instructed by your intermediary). This gives your intermediary time to submit the revocation to Computershare Trust Company of Canada. If your revocation is not received in time, your intermediary is not required to act on it.

Page 8    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

Registered shareholders

You may revoke your proxy or voting instructions in any of the following ways:

Who is soliciting my proxy and distributing proxy-related materials?

Thomson Reuters management and directors may solicit your proxy for use at the meeting and any adjourned or postponed meeting. Our management and directors may solicit proxies by mail and in person. We are paying all costs of solicitation. Intermediaries will distribute proxy-related materials directly to non-objecting beneficial owners on our behalf. We are paying for intermediaries to send proxy-related materials to both non-objecting beneficial owners and objecting beneficial owners.

Is my vote confidential?

Yes. Our registrar, Computershare Trust Company of Canada, independently counts and tabulates the proxies to preserve the confidentiality of individual shareholder votes. Proxies are referred to us only in cases where a shareholder clearly intends to communicate with management, in the event of questions as to the validity of a proxy or where it is necessary to do so to meet applicable legal requirements.

Voting results

Following the meeting, we will post the voting results in the “Investor Relations” section of our website, www.thomsonreuters.com. We will also file a copy of the results with the Canadian securities regulatory authorities at www.sedar.com and the U.S. Securities and Exchange Commission at www.sec.gov.

Electronic Delivery of Shareholder Communications

Does Thomson Reuters provide electronic delivery of shareholder communications?

Yes. Electronic delivery is a voluntary program for our shareholders. Under this program, an e-mail notification (with links to the documents posted on our website) is sent to you.

Principal Shareholder and Share Capital

As of April 16, 2018, Woodbridge beneficially owned 451,112,512 of our common shares, or approximately 63% of our outstanding common shares. Woodbridge is the principal and controlling shareholder of Thomson Reuters.

Woodbridge, a private company, is the primary investment vehicle for members of the family of the late Roy H. Thomson, the first Lord Thomson of Fleet. Woodbridge is a professionally managed company that, in addition to its controlling interest in Thomson Reuters, has other substantial investments.

Prior to his passing in 2006, Kenneth R. Thomson controlled our company through Woodbridge. He did so by holding shares of a holding company of Woodbridge, Thomson Investments Limited. Under his estate arrangements, the 2003 TIL Settlement, a trust of which the trust company subsidiary of a Canadian chartered bank is trustee and members of the family of the late first Lord Thomson of Fleet are beneficiaries, holds those holding company shares. Kenneth R. Thomson established these arrangements to provide for long-term stability of the business of Woodbridge. The equity of Woodbridge continues to be owned by members of successive generations of the family of the first Lord Thomson of Fleet.

Under the estate arrangements of Kenneth R. Thomson, the directors and officers of Woodbridge are responsible for its business and operations. In certain limited circumstances, including very substantial dispositions of our company’s common shares by Woodbridge, the estate arrangements provide for approval of the trustee to be obtained.

On January 30, 2018, our company announced that we intend to use a portion of the proceeds from the Financial & Risk strategic partnership transaction (estimated at US$9 – US$11 billion) to repurchase common shares via a substantial issuer bid/tender offer to be made to all shareholders following closing of the transaction, which is expected to be in the second half of 2018. We expect Woodbridge will participate in the issuer bid/tender offer. Upon completion of the transaction, Woodbridge’s ownership percentage of our company is expected to be between 50% and 60%.

Note 29 to our 2017 annual consolidated financial statements provides information on certain transactions that we entered into with Woodbridge in 2017 and 2016.

To our knowledge, no other person beneficially owns, directly or indirectly, 10% or more of our common shares.

About Our Directors

This section includes the following information:

HIGHLIGHTS

Voting

You will be asked to vote for each director on an individual basis. Each nominee is proposed to be elected for a term ending at our 2019 annual meeting of shareholders. All of the nominees are currently directors of our company. Each nominee was elected at our 2017 annual and special meeting of shareholders. Profiles for each nominee are provided on the following pages.

The board unanimously recommends that you vote FOR the election of the following 11 nominees to the Thomson Reuters board of directors: David Thomson, James C. Smith, Sheila C. Bair, David W. Binet, W. Edmund Clark, C.M., Michael E. Daniels, Vance K. Opperman, Kristin C. Peck, Barry Salzberg, Peter J. Thomson and Wulf von Schimmelmann.

Management does not believe that any of the nominees will be unable to serve as a director but, if this should occur for any reason prior to the meeting, the persons named in the enclosed proxy form may vote for another nominee at their discretion.

Following the meeting, we will issue a press release that includes the number of votes cast for and withheld from each individual director.

Majority voting policy

We have a majority voting policy that applies to the election of directors at the annual meeting of shareholders. This means that if a director receives more “withhold” votes than “for” votes at the meeting, then the director will immediately tender his or her resignation to the Chairman. This would be effective if accepted by the board. The Corporate Governance Committee will consider a director’s offer to resign and make a recommendation to the board as to whether to accept it. The board will accept resignations, except in exceptional circumstances. The board will have 90 days from the annual meeting to make and publicly disclose its decision by news release either to accept or reject the resignation (including reasons for rejecting the resignation, if applicable).

Director qualifications

We believe that all of the director nominees possess character, integrity, judgment, business experience, a record of achievement and other skills and talents which enhance the board and the overall management of the business and affairs of Thomson Reuters. Each director nominee has an understanding of our company’s principal operational and financial objectives, plans and strategies, financial position and performance and the performance of Thomson Reuters relative to our principal competitors. The Corporate Governance Committee considered these qualifications in determining to recommend the director nominees for election. Additional information is provided in the individual director profiles below and in the “Board Committees – Corporate Governance Committee” section of this circular, which contains a “skills matrix” highlighting individual director skills and experiences.

Independence

A majority of the board is independent. Under the corporate governance guidelines adopted by the board, a director is not considered independent unless the board affirmatively determines that the director has no “material relationship” with Thomson Reuters. In determining the independence of directors, the board considers all relevant facts and circumstances. In April 2018, the board conducted

Page 12    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

its annual assessment of the independence of each of its current members and determined that six of the 11 directors (approximately 55%) serving on the board and proposed to be elected at the meeting are independent. In determining independence, the board examined and relied on the applicable definitions of “independent” in the NYSE listing standards and Canadian Securities Administrators’ National Instrument 58-101. The board also reviewed the results of questionnaires completed by directors.

In order for the board to function independently from management:

None of Messrs. D. Thomson, Binet or P. Thomson is a member of Thomson Reuters executive management team. With its substantial equity investment in Thomson Reuters, Woodbridge considers that its interests as a shareholder are aligned with those of all other shareholders.

In determining the independence of directors, the board also considers that in the normal course of business, we provide services to, and receive services from, companies with which some of the independent directors are affiliated. Based on the specific facts and circumstances, the board determined in April 2018 that these relationships were immaterial.

Interlocking Directorships

We do not have any directors who serve together on boards of other public companies. The board has adopted a policy that no more than two of our directors may serve together on the boards of other public companies without the consent of the Corporate Governance Committee.

Service on Other Boards

Our directors are not restricted from serving on the boards of other public or private companies so long as their commitments do not materially interfere with or are not incompatible with, their ability to fulfill their duties as a member of our company’s board. However, directors must receive approval from the Chair of the Corporate Governance Committee in advance of accepting an invitation to serve on the board of another public company and must notify the Chair of the Corporate Governance Committee in connection with accepting an invitation to serve on the board of a for-profit private company that is not a family business. The Corporate Governance Committee monitors the outside boards that our directors sit on to determine if there are circumstances that would impact a director’s ability to exercise independent judgment and to ensure that a director has sufficient time to fulfill his or her commitments to Thomson Reuters.

Tenure

Our board has not adopted a mandatory retirement age or term limits for individual directors. We believe that individuals can continue to remain effective directors beyond a mandated retirement age or maximum period of service. Without having a

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 13

mandatory retirement age or term limits, we have experienced turnover on our board that has brought directors with new perspectives and approaches. This has complemented the depth of knowledge and insight about our company and business operations that some of our more long-standing directors have developed over time. Of the 11 directors proposed to be elected at this year’s meeting, only three (approximately 27%) were members of our board in 2008 when Thomson Reuters was formed. The following table shows the tenure of our director nominees on our board.

The average tenure of all director nominees is 9.9 years and the average tenure of nominees who are considered independent is 7 years.

Two of our directors who have been members of the board for more than 10 years (David Thomson and Peter Thomson) are affiliated with our company’s principal shareholder, Woodbridge.

Countries of Residence

The following table shows the countries where our director nominees ordinarily reside.

Nominee Information

The following provides information regarding the 11 director nominees who are proposed to be elected at the meeting, including a brief biography, city and country of residence, the year that they were appointed to our board, independence status, primary areas of expertise, committee membership, attendance at board and committee meetings in 2017 and ownership of Thomson Reuters securities.

In the director nominee profiles on the following pages, “securities held” by a director nominee includes common shares over which a director exercised control or direction, and the number of restricted share units (RSUs), deferred share units (DSUs) and options held by, or credited to, each individual as of April 16, 2018. Information regarding common shares beneficially owned does not include shares that may be obtained through the exercise or vesting of options, RSUs or DSUs. Each director nominee provided us with information about how many common shares he or she beneficially owns.

The market value of shares beneficially owned is based on the closing price of our common shares on the New York Stock Exchange (NYSE) on April 16, 2018, which was $39.37. The market value of DSUs is also based on the closing price of our common shares on the NYSE on that date.

We have also included information about each director nominee’s ownership of Thomson Reuters common shares and DSUs as of April 16, 2018 as a multiple of their annual retainer. Additional information about director share ownership guidelines is provided later in this section.

Our Corporate Governance Committee is responsible for periodically reviewing the adequacy and form of directors’ compensation. In 2017, the Corporate Governance Committee reviewed our director compensation program and decided not to change the form or amount of director compensation.

In periodically benchmarking director compensation, the Corporate Governance Committee evaluates publicly available data related to director compensation paid by large U.S. and Canadian public companies, as our company’s board is primarily comprised of directors from the U.S. and Canada. U.S. board compensation is generally higher than Canadian companies.

We do not grant stock options, restricted share units (RSUs) or bonuses to our non-management directors. In addition, we do not provide our non-management directors with retirement/pension benefits, healthcare coverage or perquisites.

As discussed later in this section, we require our directors to hold a minimum value of common shares and/or deferred share units (DSUs) and our director compensation program encourages directors to invest in our company beyond their minimum ownership requirements.

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 21

Our directors have a mandatory equity component for their compensation. Approximately 81% of director compensation was paid in equity (DSUs or common shares) in 2017.

Components of Director Compensation

The table below sets forth the annual retainers that were payable to our directors in 2017. Directors do not receive separate attendance or meeting fees. Chairs of the Audit Committee and HR Committee receive additional fees given their increased responsibilities and workloads. Additional information regarding the different components of our director compensation structure is provided following this table.

Retainers / Mandatory Equity Component

We require a minimum of $50,000 of each director’s $200,000 annual retainer to be paid in equity in the form of DSUs (payable quarterly). Our non-management directors then elect to receive the remaining $150,000 of their $200,000 annual retainer in the form of DSUs, common shares or cash (or a mix thereof – payable quarterly).

DSUs

Each DSU has the same value as one common share, though DSUs do not have voting rights. DSUs are not performance-based units. If a director elects to receive DSUs, units representing the value of common shares are credited to the director’s account. DSUs accumulate additional units based on notional equivalents of dividends paid on our common shares. DSUs are fully vested upon grant, but they are only settled (in the form of common shares or cash, at the election of the director) following termination of the director’s board service. Any common shares delivered to a director in connection with the settlement of DSUs are purchased in the open market.

Common Shares

If a director elects to receive common shares, the cash amount (net of withholding taxes) is provided to our broker who uses such amount to buy shares in the open market.

Committee Fees

Committee chair fees, which are payable entirely in DSUs, are reflected in the table above.

Chairman and Deputy Chairman Retainer

The Chairman’s annual retainer is $600,000. The Deputy Chairman’s annual retainer is $150,000, which is payable entirely in DSUs. The Deputy Chairman also receives the same annual $200,000 retainer paid to other non-management directors. Additional information about the Chairman and the Deputy Chairman is provided later in the “Corporate Governance Practices” section of this circular.

Lead Independent Director Retainer

The Lead Independent Director’s annual retainer is $150,000, which is payable entirely in DSUs and is inclusive of the fee for chairing one committee. The Lead Independent Director also receives the same annual $200,000 retainer paid to other

Page 22    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

non-management directors. Additional information about the Lead Independent Director is provided later in the “Corporate Governance Practices” section of this circular.

2018 Director Compensation

No changes are currently contemplated at this time to the amount or form of director compensation for 2018.

Total Director Compensation

The table below reflects compensation earned by our directors in 2017. Approximately 81% of 2017 director compensation was paid in DSUs and common shares.

As President and CEO of Thomson Reuters, Mr. Smith does not receive compensation for his service as a director. Information regarding Mr. Smith’s 2017 compensation is set forth in the “Executive Compensation” section of this circular.

Stock Option and RSU Grants

Our non-management directors are not eligible to receive stock option grants and no non-management director currently holds any options. None of our non-management directors currently hold RSUs. Options and RSUs held by Mr. Smith are described later in the circular.

Share Ownership Guidelines

Directors are required to hold common shares and/or DSUs with a value of $600,000, which is equal to three times their annual retainer. Directors are required to meet their ownership requirement within five years of the date of their initial appointment to the Thomson Reuters board. Share prices of all public companies are subject to market volatility. As a result, director share ownership guidelines reflect a “once met, always met” standard. This means that if a director has met his or her applicable ownership guideline multiple and a subsequent decline in the Thomson Reuters share price causes the value of his or her ownership to fall below the applicable threshold, the director will be considered to be in compliance with the guidelines so long as he or she continues to hold the number of shares that were owned at the time when he or she achieved the guidelines.

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 23

Ownership of common shares and DSUs by our director nominees can be found in each nominee’s biography in this circular. David Thomson and Peter Thomson are substantial shareholders of our company as members of the family that owns the equity of Woodbridge. As of April 16, 2018, Woodbridge beneficially owned approximately 63% of our common shares. For more information, see the “Principal Shareholder and Share Capital” section of this circular. The following table shows each non-management director’s progress towards his or her share ownership guidelines. All ownership multiples and each director’s ownership are as of April 16, 2018.

Mr. Smith is subject to separate ownership guidelines in his capacity as CEO of our company. For more information, see the “Compensation Discussion and Analysis” section of this circular.

Pensions

Non-management directors do not receive any pension benefits from our company. Mr. Smith’s pension and retirement benefits are described in the “Executive Compensation – Pension and Other Retirement Benefits” section of this circular.

Service Contracts

We have not entered into service contracts with our non-management directors. Our agreement with Mr. Smith regarding termination benefits is described in the “Executive Compensation – Termination Benefits” section of this circular.

Liability Insurance

We provide our directors with liability insurance in connection with their service on the board.

Director Expenses

We reimburse directors for reasonable travel and out-of-pocket expenses incurred in connection with their Thomson Reuters duties.

Corporate Governance Practices

Our board is committed to high standards of corporate governance and believes that sound corporate governance practices are essential to the well-being of our company and for the promotion and protection of our shareholders’ interests. We believe that sustainable value creation for all shareholders is fostered through a board that is informed and engaged and that functions independently of management.

As a public company with shares listed in Canada on the Toronto Stock Exchange and in the United States on the New York Stock Exchange, our corporate governance practices are generally consistent with the best practice guidelines of the Canadian securities regulatory authorities and the SEC. In addition, our corporate governance practices comply with most of the corporate governance listing standards of the NYSE, notwithstanding that we are exempt from most of those standards as a “foreign private issuer”.

Board Composition and Responsibilities

Governance Structure

The board oversees our corporate governance structure, in part, through the work of the Corporate Governance Committee. Board practices are set out in corporate governance guidelines, which the Corporate Governance Committee reviews annually. The corporate governance guidelines deal with issues such as the board’s duties and responsibilities, share ownership guidelines and conflicts of interest. In addition, each of the board’s three committees (Audit, Corporate Governance and HR) has a charter. The charters are reviewed annually by the relevant committee and the Corporate Governance Committee.

The board’s principal responsibilities include strategic planning, risk management, financial reporting, disclosure and corporate governance.

Our Code of Business Conduct and Ethics (Code), which was updated in February 2018, applies to our employees, directors and officers, including our CEO, CFO and Controller. Our updated Code reflects changes in style and appearance. While the content of the updated Code and its provisions are fundamentally the same, it also reflects certain content updates to make the Code consistent with policies and regulations that have changed in the last few years. Our employees, directors and officers are required to submit an acknowledgment that they have received and read a copy of the Code and understand their obligations to comply with the principles and policies outlined in it. The Corporate Governance Committee receives an annual report regarding the Code from the General Counsel.

Board Size

The board currently consists of 11 individuals and functions independently of management. The board is currently comprised of 10 non-management directors and the CEO. Individual directors are proposed for election annually. We have proposed all 11 directors to be nominated for election at the meeting.

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 25

Key Responsibilities of the Board

The fundamental responsibility of the board is to supervise the management of the business and affairs of Thomson Reuters. The table below highlights primary activities and topics from the board’s 2017 work plan.

Strategic Planning

The board plays an important role in strategic planning and direction throughout the year.

In January, the board meets with management to review, discuss and approve the final version of our annual operating plan, which is prepared by our CEO, CFO and other senior executives. The plan typically addresses:

Page 26    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

Throughout the year, the board and management discuss our progress against the plan. The board focused its in-person meeting in September on corporate strategy. As part of this meeting, directors had an in-depth discussion about our company’s strategic plans with our CEO, CFO, Chief Strategy Officer and other senior executives. Strategy discussions typically cover topics such as technology, the current condition of our business segments, future growth potential of our businesses and the key market segments that we serve, and how we are seeking to increase shareholder value.

While the January and September meetings focus on strategic planning, the board also discusses various strategic issues with management at other meetings during the year. For example, the board discussed our capital strategy with the CFO and the Treasurer at the November meeting. In addition, various presidents of our business units provide updates to the board at meetings during the year and those discussions typically address the unit’s current operations and strategic objectives.

Risk Oversight

The board is responsible for confirming that a system is in place to identify the principal risks facing Thomson Reuters and that appropriate procedures and systems are in place to monitor, mitigate and manage those risks.

The ERM process at our company includes:

Our enterprise risk management (ERM) process is designed to enhance the identification and mitigation of risk throughout Thomson Reuters and assist the board and the Audit Committee with oversight responsibility for risk management.

In 2016, we created a new management risk committee to track and monitor enterprise risks. This committee assesses the status of identified risks and reviewing the adequacy of applicable mitigation plans. The management risk committee is co-chaired by the Chief Transformation Officer and the General Counsel, who provide direction, prioritization, executive support and communication. Executives responsible for specific risk mitigation periodically report to the Audit Committee, the board or other board committees, as appropriate. Risk committee members are comprised of various Thomson Reuters senior leaders from Corporate functional departments and each business unit. An ERM owner who works with the risk committee to plan the annual process is also responsible for collecting and consolidating Corporate and business unit identified risks.

For our business units and functional departments, ERM is an ongoing process under continuous management review. We involve our Corporate Compliance and Audit department in the review of certain identified risks, as appropriate or upon request. Mr. Smith’s executive committee undertakes a formal risk review at least annually.

As discussed later in the circular, the Audit Committee is primarily responsible for overseeing management’s ERM process. Enterprise risk owners report to the Audit Committee, the board or a different board committee during the year regarding their identified enterprise risks.

The HR Committee’s responsibilities include establishing, implementing and overseeing our compensation policies and programs. We have designed our compensation programs to provide an appropriate balance of risk and reward in relation to the company’s overall business strategy. Please see the “Compensation Discussion and Analysis” section of this circular for additional information regarding why we believe that our compensation programs do not incentivize our executives to take unnecessary or excessive risks.

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 27

Separate Chairman and CEO

The roles and responsibilities of the Chairman and the CEO of our company are separate to allow for more effective oversight and to hold management more accountable.

Deputy Chairman

David Binet is the board’s Deputy Chairman. The Deputy Chairman works collaboratively with the Chairman and assists the Chairman in fulfilling his responsibilities. The Deputy Chairman also engages in regular dialogue with the Chairman, the CEO and the Lead Independent Director to reinforce our culture of good governance; serves as an ambassador for Thomson Reuters; and performs additional duties as may be delegated to him by the Chairman or the board from time to time.

Lead Independent Director

Vance Opperman is the board’s Lead Independent Director. Among other things, responsibilities of our Lead Independent Director include chairing meetings of the independent directors; in consultation with the Chairman, Deputy Chairman and CEO, approving meeting agendas for the board; as requested, advising the CEO on the quality, quantity, appropriateness and timeliness of information sent by management to the board; and being available for consultation with the other independent directors as required.

Position Descriptions

Position descriptions for the Chairman, the chair of each committee and the Lead Independent Director have been approved by the board and help ensure the independent operations of the board and its committees.

Meetings with and without the CEO/Management

Our board typically begins each in-person meeting with an “in-camera” session with the CEO, but no other members of management. This is intended to give the CEO an opportunity to discuss his objectives for the day’s meeting, and for directors to express preliminary observations based on their prior review of meeting materials. This permits a more effective use of time in the board meeting. A similar session is typically held with the CEO at the end of the meeting, followed by a meeting of the board without the CEO or other members of management present. Board committees also utilize “in-camera” meetings for discussions without the CEO or members of management present.

Meetings of Independent Directors

At least once each year, the board meets without the CEO and without the directors affiliated with Woodbridge. These meetings of the independent directors, which follow a regularly scheduled board meeting, are chaired by the Lead Independent Director. The Lead Independent Director develops the agenda for these meetings, although discussion has not been limited to it. The agenda generally addresses any issues that might be specific to a public corporation with a controlling shareholder. The Lead Independent Director reports to the Chairman, Deputy Chairman and the CEO on the substance of these meetings to the extent that action is appropriate or required. Two meetings of the independent directors took place in 2017 which were presided over by Mr. Opperman.

Secretary

Deirdre Stanley, Executive Vice President and General Counsel, is also Secretary to the board. Directors have access to the advice and services of the Secretary.

Access to Management and Professional Advisors

The board has access to members of management and professional advisors. The board and its committees may invite any member of senior management, employee, outside advisor or other person to attend or report at any of their meetings. The board and any of its committees are able to retain an outside independent professional advisor at any time at the expense of our company and have the authority to determine the advisor’s fees and other retention terms. Individual directors are able to retain an outside independent professional advisor at the expense of our company subject to notifying the Corporate Governance Committee in advance.

The HR Committee retains an independent consulting firm to advise it on compensation matters relating to senior management. The independent consulting firm also reviews executive compensation programs and provides guidance and analysis on plan

Page 28    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

design and market trends and practices. The HR Committee also utilizes and relies upon market survey data provided by a consulting firm regarding executive compensation for organizations of comparable size and scope with which Thomson Reuters is most likely to compete for executive talent. Additional information is provided in the “Compensation Discussion and Analysis” section of this circular.

Delegation of Authority

To clarify the division of responsibility between the board and management, the board has adopted a delegation of authority policy. This policy delegates certain decision-making and operating authority to senior management and has been adopted by the board in order to enhance our internal controls and allow management appropriate flexibility to deal with certain matters without obtaining specific board approval. The board also delegates certain responsibilities to the Audit Committee, Corporate Governance Committee and HR Committee, and oversees the committees’ fulfillment of their responsibilities. The responsibilities of each committee are described in more detail below.

Director Attendance

The board meets regularly in order to discharge its duties effectively. Directors are expected to attend all meetings of the board including committee meetings, if applicable, and annual meetings of shareholders. The following table provides information about the number of board and committee meetings in 2017.

Five of the board’s nine meetings in 2017 were held in person. Four special meetings were held telephonically during the year, three of which related to our company’s proposed Financial & Risk partnership.

The following table sets forth the attendance of our directors at board and committee meetings in 2017. In 2017, average attendance for these individuals at all board and committee meetings was 96% and approximately 95%, respectively.

Mary Cirillo and P. Thomas Jenkins served on the board between January 1, 2017 and May 3, 2017 and did not stand for re-election last year. In 2017, Ms. Cirillo attended 3 of 3 board meetings, 2 of 2 meetings of the Corporate Governance Committee and 3 of 4 meetings of the HR Committee. Mr. Jenkins attended 3 of 3 board meetings and 4 of 4 meetings of the Audit Committee.

Sir Kenneth Olisa resigned from the board on January 30, 2018. In 2017, Sir Kenneth attended 7 of 9 board meetings and 8 of 8 meetings of the Audit Committee.

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 29

Controlled Company

Our company is a “controlled company” as a result of Woodbridge’s ownership.

The NYSE corporate governance listing standards require a listed company to have, among other things, solely independent directors on its compensation committee and nominating/corporate governance committee. A “controlled company” (as defined by the NYSE) is a company of which more than 50% of the voting power is held by an individual, group or another company and is exempt from these requirements.

Supplemental guidelines issued by the Canadian Coalition for Good Governance (CCGG) address controlled companies. A “controlled company” (as defined by CCGG) includes corporations with a controlling shareholder who controls a sufficient number of shares to be able to elect the board of directors or to direct the management or policies of the corporation.

While a majority of members of each of the Corporate Governance Committee and the HR Committee of our company are independent, the board believes it is appropriate for Messrs. Binet and Clark, who are not considered to be independent under applicable rules because of their affiliation with Woodbridge, to serve on these committees and has approved our reliance on the NYSE’s controlled company exemption to do so. CCGG has stated that it believes it is appropriate for directors who are related to the controlling shareholder to sit on these committees to bring the knowledge and perspective of the controlling shareholder to executive compensation, appointments and board nominations.

No directors affiliated with Woodbridge serve on our Audit Committee, which is required to have solely independent directors.

Page 30    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

Board Committees

This section provides information about the board’s three committees (Audit, Corporate Governance and HR), including each committee’s responsibilities, members and activities in 2017. Additional information about each committee is provided below. The following table sets forth the membership of our three board committees.

Each of the board’s committees has a charter. The charters are reviewed annually by the relevant committee and the Corporate Governance Committee. These charters and a committee chair position description are publicly available at www.thomsonreuters.com.

Audit Committee

Responsibilities

The Audit Committee is responsible for assisting the board in fulfilling its oversight responsibilities in relation to:

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 31

In the course of fulfilling its mandate, the Audit Committee focused on several topics in 2017, which are reflected in the work plan below.

Financial Literacy

All members of the Audit Committee are financially literate in accordance with applicable Canadian and U.S. securities rules. Mr. Salzberg qualifies as an “audit committee financial expert” (within the meaning of applicable SEC rules) and meets applicable tests for accounting or related financial management expertise within the meaning of NYSE listing standards.

Audit Committee Members’ Education and Experience

The following is a brief summary of the education and experience of each member of the Audit Committee that is relevant to the performance of his or her responsibilities. In May 2017, Mr. Salzberg became the new Chair of the Audit Committee. Mr. Opperman had previously served as the Chair of the Audit Committee for over 15 years and remains a member of the committee. Mr. Daniels was appointed to the Audit Committee in April 2018.

Page 32    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

Financial Reporting

The Audit Committee meets to discuss and review our:

As is customary for a number of global multinational companies, the board of directors has delegated review and approval authority to the Audit Committee for our quarterly earnings releases, MD&A and financial statements. Following the Audit Committee’s recommendation, the full board reviews and approves our annual MD&A and annual audited financial statements, as required by applicable law.

Prior to an Audit Committee meeting at which draft financial reporting documents will be discussed, a draft is distributed to the members of the Audit Committee for review and comment. The CFO and the Chief Accounting Officer and a representative from the independent auditor meet with the Chair of the Audit Committee to preview the audit-related issues which will be discussed at the Audit Committee meeting. At the Audit Committee meeting, the Chief Accounting Officer discusses the financial statements and disclosure matters and the Audit Committee members are given an opportunity to raise any questions or comments. The independent auditor also participates in the meeting. All of our directors are also provided with a draft and an opportunity to comment before or during the Audit Committee meeting. When the Audit Committee is satisfied with the disclosure, it provides its approval and the material is released.

For the annual report, a draft is distributed to the members of the board in advance of a board meeting for their review and approval. At the board meeting, directors are given an opportunity to raise any questions or comments.

Based upon the reports and discussions described in this circular, and subject to the limitations on the role and responsibilities of the Audit Committee in its charter, the Audit Committee recommended that our board approve the filing of the audited consolidated financial statements and related MD&A and their inclusion in our annual report for the year ended December 31, 2017.

Risk Management

The Audit Committee periodically meets with senior management to review the company’s controls and policies regarding risk assessment and risk management, including the steps and process taken to monitor and control risks.

In February 2017, senior management presented an overview of its 2017 enterprise risk management (ERM) process to the Audit Committee. The overview reflected key risks identified by management and a proposed calendar of future meetings for “deep dive” reviews and discussions about specific risks (at the board or Audit Committee level).

As part of its risk management oversight responsibilities, the Audit Committee met with management in 2017 to discuss financial regulatory compliance, treasury risk management, information security and disaster recovery initiatives and the external tax environment.

Independent Auditor

The Audit Committee is responsible for selecting, evaluating and recommending for nomination the independent auditor to be proposed for appointment or re-appointment. The Audit Committee recommended that PricewaterhouseCoopers LLP be re-appointed as our independent auditor to serve until our next meeting of shareholders in 2019 and that our board submit this appointment to shareholders for approval at the 2018 annual and special meeting of shareholders. In connection with recommending PricewaterhouseCoopers LLP, the Audit Committee considered the firm’s provision of services to Thomson Reuters over the last year, including the performance of the lead audit engagement partner and the audit team. The Audit Committee also reviewed the appropriateness of PricewaterhouseCoopers LLP’s fees in relation to the size of Thomson Reuters and its global footprint. The Audit Committee continues to be satisfied with PricewaterhouseCoopers LLP’s performance and believes that its continued retention as independent auditor is in the best interests of Thomson Reuters and its shareholders.

Throughout the year, the Audit Committee evaluates and is directly responsible for our company’s relationship with PricewaterhouseCoopers LLP. The Audit Committee appoints PricewaterhouseCoopers LLP as our independent auditor after reviewing and approving its engagement letter. The Audit Committee also determines PricewaterhouseCoopers LLP’s fees.

The Audit Committee and representatives from PricewaterhouseCoopers LLP meet several times during the year. In 2017, representatives from PricewaterhouseCoopers LLP attended each Audit Committee meeting and met with the Audit Committee in separate sessions.

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 33

PricewaterhouseCoopers LLP is accountable to the Audit Committee and reports directly to the Audit Committee.

On an annual basis, before PricewaterhouseCoopers LLP issues its report on our company’s annual financial statements, the Audit Committee:

The Audit Committee has also adopted a policy regarding its pre-approval of all audit and permissible non-audit services provided to our company by PricewaterhouseCoopers LLP.

The Audit Committee’s charter allows the Audit Committee to delegate to one or more members the authority to evaluate and approve engagements in the event that the need arises for approval between Audit Committee meetings. Pursuant to this charter provision, the Audit Committee has delegated this authority to its Chair. If the Chair approves any such engagements, he must report his approval decisions to the full Audit Committee at its next meeting. For the year ended December 31, 2017, none of the audit-related, tax or all other fees of Thomson Reuters described above made use of the de minimis exception to pre-approval provisions contained in Rule 2-01(c)(7)(i)(c) of SEC Regulation S-X and Section 2.4 of the Canadian Securities Administrators’ Multilateral Instrument 52-110 (Audit Committees).

Internal Audit and Internal Control Over Financial Reporting

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with international financial reporting standards. Our company has adopted the Committee of Sponsoring Organizations of the Treadway Commission guidance for implementing our internal control framework as part of compliance with the Sarbanes-Oxley Act and applicable Canadian securities law.

The Corporate Compliance and Audit department of our company, which performs an internal audit function, prepares and oversees the overall plan for our internal control over financial reporting.

Each year, Corporate Compliance and Audit identifies certain processes, entities and/or significant accounts to be within the scope of its internal control focus areas and testing for the year. In determining the proposed scope of its annual internal audit plan, the Corporate Compliance and Audit department identifies, assesses and prioritizes risk to Thomson Reuters and considers both quantitative and qualitative factors.

In the first quarter of 2017, Corporate Compliance and Audit presented an annual internal audit plan to the Audit Committee for its review and approval. The Corporate Compliance and Audit department then provided updates to the Audit Committee at meetings throughout the year. During the second half of 2017, the Corporate Compliance and Audit department tested applicable controls in order to achieve compliance with the required year-end evaluation of the effectiveness of the internal control system.

Page 34    Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders

Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2017. In February 2018, the Audit Committee reviewed and discussed with management its assessment and report on the effectiveness of our internal control over financial reporting as of December 31, 2017. The Audit Committee also reviewed and discussed with PricewaterhouseCoopers LLP its review and report on the effectiveness of our internal control over financial reporting.

The head of the Corporate Compliance and Audit department reports directly to the Audit Committee (with a dotted line reporting relationship to our CFO).

Disclosure and Communications Controls and Procedures

We have adopted disclosure controls and procedures to ensure that all information required to be disclosed by us in reports and filings with Canadian and U.S. securities regulatory authorities and stock exchanges and other written and oral information that we publicly disclose is recorded, processed, summarized and reported accurately and within the time periods specified by rules and regulations of the securities regulatory authorities. These disclosure controls and procedures are also designed to ensure that this information is accumulated and communicated to management (including the CEO and CFO), as appropriate, to allow timely decisions regarding required disclosure. The Audit Committee receives an annual update from management regarding the adequacy and effectiveness of our disclosure controls and procedures, including the role and responsibilities of management’s disclosure committee.

As required by applicable Canadian and U.S. securities laws, our CEO and CFO provide certifications that they have reviewed our annual and quarterly reports, that the reports contain no untrue statements or omissions of material facts and that the reports fairly present our financial condition, results of operations and cash flows. In addition, the CEO and CFO make certifications regarding our disclosure controls and procedures and internal control over financial reporting. Our CEO and CFO concluded that our disclosure controls and procedures were effective as of December 31, 2017.

On a day-to-day basis, inquiries or other communications from shareholders, analysts and the media to management are answered by our investor relations and media relations departments or referred to another appropriate person in our company.

Senior executives meet regularly with financial analysts and institutional investors, and our earnings conference calls are broadcast live via webcast and are accessible to interested shareholders, the media and members of the public. Presentations given by senior executives at investor conferences are promptly made public in the “Investor Relations” section of our website. Some of our non-management directors have attended our Investor Day meetings with analysts and major shareholders.

Whistleblower Policy

The Audit Committee has adopted procedures for the receipt, retention and treatment of complaints received by our company regarding accounting, internal accounting controls, auditing matters, and disclosure controls and procedures, as well as procedures for the confidential, anonymous submission of concerns by our employees regarding questionable accounting, internal accounting controls, auditing matters or disclosure controls and procedures. These procedures are set forth in the Thomson Reuters Code of Business Conduct and Ethics, which is described earlier in this circular.

Corporate Governance Committee

The Corporate Governance Committee is responsible for assisting the board in fulfilling its oversight responsibilities in relation to:

Management Proxy Circular and Notice of Annual and Special Meeting of Shareholders    Page 35

The following table sets forth the Corporate Governance Committee’s work plan for 2017.

Skills and Experiences of Directors

We believe that our board reflects an appropriate mix of directors with different skills and experiences. The following table, or skills matrix, summarizes the skills and areas of experience indicated by each director nominee proposed to be elected at the annual and special meeting of shareholders. Our board believes that these skills and experiences are necessary for it to carry out its mandate. The Corporate Governance Committee takes our skills matrix into consideration when identifying potential new director candidates. The skills matrix is reviewed and updated annually.
