TELUS International | 2023 Information Circular Information about voting About the meeting and our Board Holders of record of subordinate voting shares and/or multiple voting shares on the Record Date are entitled to notice of, and to vote at, our annual general meeting or any adjournment thereof. There were 73,202,309 subordinate voting shares and 199,931,876 multiple voting shares outstanding on March 13, 2023. The subordinate voting shares are “restricted securities”, within the meaning of such term under applicable Canadian securities laws, in that they do not carry equal voting rights with the multiple voting shares. Each multiple voting share carries the right to ten votes per multiple voting share held and each subordinate voting share carries the right to one vote per subordinate voting share held. In aggregate, all the voting rights associated with the subordinate voting shares represented, as of March 13, 2023, approximately 3.53 per cent of the voting rights attached to all of the Company’s issued and outstanding shares. Under applicable securities laws in Canada, an offer to purchase multiple voting shares would not necessarily require that an offer be made to purchase subordinate voting shares. In accordance with the rules of the Toronto Stock Exchange (TSX) designed to ensure that, in the event of a take-over bid, the holders of subordinate voting shares will be entitled to participate on an equal footing with holders of multiple voting shares, the holders of multiple voting shares upon completion of our initial public offering entered into a customary coattail agreement with the Company and a trustee (the Coattail Agreement). The Coattail Agreement contains provisions customary for dual-class, TSX-listed corporations designed to prevent transactions that otherwise would deprive the holders of subordinate voting shares of rights under applicable securities laws in Canada to which they would have been entitled if the multiple voting shares had been subordinate voting shares. To the knowledge of the Directors and the Company’s executive leadership team (ELT) of TELUS International, as of March 13, 2023, ďÒÀõîçĦāÀĄĈõîĈõĄ¶õíā¨îÕÀĈďÒ¨ďµÀîÀŵ¶Õ¨ççĦõĠîÀ¼ǿ¼ÕĄÀ¶ďçĦõĄÕî¼ÕĄÀ¶ďçĦǿõĄÀĥÀĄ¶ÕĈÀ¼¶õîďĄõçõĄ¼ÕĄÀ¶ďÕõîõğÀĄǿƉƈāÀĄ¶ÀîďõĄíõĄÀ of the voting rights attached to any class of outstanding shares are the following: (1) Consists of shares held by TELUS Communications, Inc., 1276431 B.C.

Multiple voting shares held by TELUS are convertible into an equivalent number of subordinate voting shares. If TELUS were to convert all its multiple voting shares into subordinate voting shares, it would hold 69.8 per cent of our subordinate voting shares and 21.0 per cent of our voting power.

TELUS International management will solicit proxies either by mail to your latest address shown on the register of shareholders or by electronic mail to the email address you provided. Additionally, TELUS International employees and/or agents may solicit proxies by telephone or other ways at a nominal cost to the Company. Canadian securities rules (Notice and Access) permit us to provide our non-registered shareholders with electronic access to the information circular and the annual report for the meeting instead of sending a paper copy. This means that the information circular and annual report are posted online for non-registered shareholders to access, rather than being mailed. Notice and Access is more environmentally friendly, as it helps reduce paper and energy use and also reduces printing and mailing costs. Non-registered shareholders will still receive forms of proxy or voting instruction forms in the mail so that they can vote their shares. However, unless a non-registered shareholder previously requested a paper copy, rather than receiving a paper copy of the circular and the annual report, they will receive a notice that has instructions on how to access and review an electronic copy of our information circular and annual report and how to request a paper copy. The notice also provides instructions on voting shares using the various voting methods provided (internet, telephone and mail). If non-registered shareholders would like to receive a paper copy of our information circular and annual report, please follow the instructions in the notice. Registered shareholders will continue to receive a paper copy of our information circular and form of proxy. Your voting instructions provided by proxy give discretionary authority to the person you appoint as proxyholder to vote as they see ŵďõî¨îĦ¨íÀî¼íÀîďõĄğ¨ĄÕ¨ďÕõîďõ¨îĦõËďÒÀí¨ďďÀĄĈÕ¼ÀîďÕŵÀ¼ÕîďÒÀîõďÕ¶ÀõËíÀÀďÕîÌõîā¨ÌÀƎ¨î¼¨îĦõďÒÀĄí¨ďďÀĄĈďÒ¨ďí¨Ħ properly be brought before the meeting, to the extent permitted by law, whether or not the amendment or other matter that comes before the meeting is routine and whether or not the amendment or other matter that comes before the meeting is contested.

Given this, the Company will continue to assess the need for and timing of a say on pay vote and has decided to forgo an advisory say on pay vote at this meeting.

TELUS International | 2023 Information Circular About our nominated directors We have elected to be treated as a “controlled company” under the listing requirements of the NYSE because more than 50 per cent of the combined voting power of our multiple voting shares and subordinate voting shares is held by TELUS and certain of its subsidiaries. We intend to rely upon the “controlled company” exemption relating to the Board of Directors and committee independence requirements under the NYSE listing requirements until we are no longer eligible or until we determine otherwise. Pursuant to this exemption, we are exempt from, among other things, the listing requirements that would otherwise require that our Board consist of a majority of independent Directors and that our Human Resources Committee and Governance and Nominating Committee be composed entirely of independent Directors. The “controlled company” exemption does not modify the independence requirements for the Audit Committee, and we comply with the requirements of the Exchange Act, the NYSE listing requirements and applicable Canadian securities laws, which require that our Audit Committee consist exclusively of independent Directors within one year following the effective date of the registration statement relating to the initial public offering, which was February 3, 2021. As of January 21, 2022, our Audit Committee was composed solely of independent Directors. Since our 2022 annual meeting of shareholders, we have added two new Directors to the Board, Madhuri Andrews and Navin Arora, effective March 9, 2023 and January 4, 2023, respectively. Two of our Directors, Kenneth Cheong and Stephen Lewis, resigned from our Board effective February 9, 2023 and January 5, 2023, respectively. At the meeting, there will be 11 Directors proposed for election to the Board. In accordance with our independence criteria (as detailed õîā¨ÌÀƌƑȭǿŵğÀõËďÒÀƉƉÕĄÀ¶ďõĄĈāĄõāõĈÀ¼ËõĄÀçÀ¶ďÕõîďõďÒÀõ¨Ą¼¨ĄÀÕî¼ÀāÀî¼ÀîďǿĄÀāĄÀĈÀîďÕîÌƌƍāÀĄ¶ÀîďõËõĔĄõ¨Ą¼ǾLçÕî îďõîǿE¨¼ÒĔĄÕî¼ĄÀĠĈǿ_ĔÀX¨ÕĈÒǿ¨ĄõçĦî_ç¨ĈäÕ¨î¼_¨î¼Ą¨_ďĔ¨Ąď¨ĄÀÀ¨¶Ò¨îɆÕî¼ÀāÀî¼Àîď¼ÕĄÀ¶ďõĄɇ¨Ĉ¼ÀŵîÀ¼ÕîďÒÀF~_ listing requirements and NI 58-101. Mr. Puritt is not considered an independent Director as he is our President and CEO.

In addition, Mr. Arora, our new nominee Director, Darren Entwistle, Doug French and Tony Geheran are not considered independent Directors as they are employees of TELUS.

In addition and over time, we aspire our Board to achieve greater geographic, age and ethnic diversity.

We believe the promotion of diversity is best served through careful consideration of all of the knowledge, experience, skills and backgrounds of each candidate for director, in light of the needs of the Board, without focusing on a single diversity characteristic. When assessing the composition of the Board, a principal focus is expected to be on ensuring the Board has the diverse experiences, skills and backgrounds needed to oversee our Company and the Company will take a balanced approach when considering the extent to which personal characteristics are taken into account.

Effective May 3, 2022, our Board, in consultation with our compensation consultant (Compensation Consultant) and as recommended by our Governance and Nominating Committee, amended the Directors compensation policy to increase the compensation received by our Directors to better align with market practices. Under the amended policy, the equity component of the compensation received by our independent Directors was increased from $120,000 to $150,000 (in the currency of their residence), while their cash retainer remained unchanged, resulting in total compensation equal to $230,000 (in the currency of their residence). To align with this, our non-independent Directors annual grant of share-settled RSUs was also increased, from a grant equal to $200,000 to $230,000 (in the currency of their residence). The additional retainer payable to the chairs of the Audit Committee and Human Resource Committee were increased from $20,000 to $25,000 and $17,500 to $20,000, respectively (in the currency of their residence). For 2022, our independent Directors were Mr. Anton, Ms. Paish, Ms. Slaski and Ms. Stuart. Our independent Directors receive a cash retainer and an equity award. Mr. Anton also received the additional equity award as chair of the Audit Committee. Cash retainer payments to our eligible Directors are made quarterly and adjusted proportionately for appointments or resignations within any quarter.

Ms. Paish and Ms. Slaski are both independent Directors. We rely upon the “controlled company” exemption relating to the board of directors and committee independence requirements under the NYSE listing requirements, pursuant to which we are exempt from, among other things, the requirements that our Governance and Nominating Committee and Human Resources Committee be composed entirely of independent Directors. However, there are no management Directors that serve on the Governance and Nominating Committee or the Human Resources Committee and the non-independent Directors who serve on these Committees are only non-independent as a result of their relationships to shareholders of the Company. Each Committee has the authority to engage outside advisors, at the expense of the Company, to provide advice with respect to a corporate decision or action. For example, the Governance and Nominating Committee may use the services of outside consultants in searching for or doing background checks on candidates and the Human Resources Committee may use the services of outside compensation consultants, legal counsel or other advisors as it determines appropriate to assist it in the full performance of its functions. Each Committee has terms of reference that set out its mandate, duties and scope of authority, and each Committee reports to the Board on its activities on a regular basis. The mandate and responsibilities of each Committee are summarized below. The following table provides an overview of our current Committees.

Governance and Nominating Committee 48

49 TELUS International | 2023 Information Circular We have elected to be treated as a “controlled company” under the listing requirements of the NYSE because more than 50 per cent of the combined voting power of our multiple voting shares and subordinate voting shares is held by TELUS and certain of its subsidiaries. We intend to rely upon the “controlled company” exemption relating to the board of directors and committee independence requirements under the NYSE listing requirements until we are no longer eligible or until we determine otherwise. Pursuant to this exemption, we are exempt from, among other things, the listing requirements that would otherwise require that our Board consist of a majority of independent Directors and that our Human Resources and Governance and Nominating Committees be composed entirely of independent Directors. The “controlled company” exemption does not modify the independence requirements for the Audit Committee, and we comply with the requirements of the Exchange Act, the NYSE listing requirements and applicable Canadian securities laws, which require that our Audit Committee be comprised exclusively of independent Directors. Since January 21, 2022, our Audit Committee has been composed solely of independent Directors. For purposes of the NYSE listing requirements, an independent director means a person who, in the opinion of our Board, has no material relationship with the Company as set forth under NYSE rules and The Exchange Act. Under NI 58-101, a director is considered to be independent if he or she is independent within the meaning of Section 1.4 of NI 52-110. Pursuant to NI 52-110, an independent director is a director who is free from any direct or indirect material relationship with us which could, in the view of our Board, be reasonably expected to interfere with the exercise of a director’s independent judgment. Our Board has undertaken a review of the independence of the Directors and considered whether any Director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each Director concerning such Director’s background, ÀíāçõĦíÀîď¨î¼¨ËŵçÕ¨ďÕõîĈǿÕî¶çĔ¼ÕîÌË¨íÕçĦĄÀç¨ďÕõîĈÒÕāĈǿõĔĄõ¨Ą¼¼ÀďÀĄíÕîÀ¼ďÒ¨ďŵğÀõËõĔĄƉƉÕĄÀ¶ďõĄĈ¨ĄÀ¨îɆÕî¼ÀāÀî¼Àîď ¼ÕĄÀ¶ďõĄɇ¨Ĉ¼ÀŵîÀ¼ÕîďÒÀF~_çÕĈďÕîÌ¨î¼ĥ¶Ò¨îÌÀ¶ďĄÀăĔÕĄÀíÀîďĈ¨î¼F0ƍƐȺƉƈƉǿĄÀāĄÀĈÀîďÕîÌƌƍāÀĄ¶ÀîďõËďÒÀõ¨Ą¼¨î¼ƍ of our 11 our Director nominees are independent as well, representing 45 per cent of the Board.

The Board will assess on a regular basis, and at least annually, the independence of Directors and, based on the recommendation of the Governance and Nominating Committee, will make a determination as to which members are independent. Mr. Puritt is not considered an independent Director as he is our President and CEO. Mr. Blair, who was the Vice-Chair of the Board for 2022 and who is expected to be reappointed as the Vice-Chair following the meeting, is not considered an independent Director as he was an employee of TELUS until December 31, 2020. In addition, Mr. Arora, one of our new Director nominee, Mr. Entwistle, Mr. French and Mr. Geheran are not considered independent Directors as they are employees of TELUS. TELUS selected Ms. Stuart, an ɆÕî¼ÀāÀî¼Àîď¼ÕĄÀ¶ďõĄɇďõŵççõîÀõËÕďĈîõíÕîÀÀāõĈÕďÕõîĈǾ We take steps to help ensure that adequate structures and processes are in place to permit our Board to function independently of management, including for purposes of encouraging an objective process for nominating Directors and determining executive compensation. In 2022, the independent Directors did not meet in the absence of the non-independent Directors. Where appropriate, our Board of Directors holds a portion of every Board meeting without members of management, including Mr. Puritt, who is a Director and also our President and CEO. Such sessions without the presence of management are presided over by the Board Chair. Interested parties may communicate any concerns to the Chair and/or our independent Directors through our ethics hotline at 1-888-265-4112 in North America, by website at https://www.telus.ethicspoint.com, or by email to corporatesecretary@ telusinternational.com. The only management Director on the Board is the President & CEO and the other non-independent Directors are only non-independent as a result of their relationships to shareholders of the Company. The roles of the CEO, Chair and Vice-Chair of the Board are separated. In addition, each Committee has full authority to retain independent external advisors to help it carry out its duties and responsibilities. In addition, our Board helps ensure open and candid discussion among its Directors by continuously monitoring situations where a ¶õîŶÕ¶ďõËÕîďÀĄÀĈďõĄāÀĄ¶ÀÕğÀ¼¶õîŶÕ¶ďõËÕîďÀĄÀĈďĠÕďÒĄÀĈāÀ¶ďďõ¨ÕĄÀ¶ďõĄí¨ĦÀĥÕĈďǾLĔĄõ¨Ą¼í¨Ħ¼ÀďÀĄíÕîÀďÒ¨ďÕďÕĈ¨āāĄõāĄÕ¨ďÀ ďõÒõç¼íÀÀďÕîÌĈÀĥ¶çĔ¼ÕîÌ¨ÕĄÀ¶ďõĄĠÕďÒ¨¶õîŶÕ¶ďõËÕîďÀĄÀĈďõĄāÀĄ¶ÀÕğÀ¼¶õîŶÕ¶ďõËÕîďÀĄÀĈďõĄĈĔ¶ÒÕĄÀ¶ďõĄí¨Ħ¶õîĈÕ¼ÀĄďÒ¨ďÕďÕĈ appropriate to recuse themselves from considering and voting with respect to the matter under consideration.

2023 Information Circular | TELUS International Our Board expects each Director to devote the time, energy and effort necessary for them to be effective. They should develop and expand their knowledge and understanding of our products, services and industry, participate in educational and development programs, and become effective ambassadors of the Company. In accordance with the Board Policy Manual, each Director is expected to attend all Board and Committee meetings. The Governance and Nominating Committee takes a Director’s attendance into consideration during the nomination process if a Director attends less than 75 per cent of Board and Committee meetings held in a year (unless due to exceptional circumstances). In 2022, there were 11 meetings of our Board. There was 100 per cent Director attendance at each of these meetings with the exception of Mr. Cheong, whose attendance was 91 per cent.

In all cases, our Directors are required to notify the Board Chair and the chair of the Governance and Nominating Committee before accepting any directorship with any other public company. We limit the number of other public company boards our Directors can serve on together. Currently, none of the Board members serve together on other public company boards. The Governance and Nominating Committee is responsible for Board and Committee succession planning and for making annual recommendations to the Board regarding the size and composition of the Board and its Committees. It also proposes new nominees for election as Directors, tracks the skills of the Company’s existing Directors and annually conducts a gap analysis. xÒÀîĄÀ¶ĄĔÕďÕîÌîÀĠÕĄÀ¶ďõĄĈǿďÒÀ'õğÀĄî¨î¶À¨î¼FõíÕî¨ďÕîÌõííÕďďÀÀǿĈĔµáÀ¶ďďõďÒÀ_Ò¨ĄÀÒõç¼ÀĄĈɉÌĄÀÀíÀîďǿÕ¼ÀîďÕŵÀĈ candidates for consideration as potential Directors and selects the names of the most suitable candidates. Such selection is made based on merit after considering the skill sets, background, experience and knowledge as prioritized by the Governance and Nominating Committee (with input from the Chair, Vice-Chair and CEO, as requested) from time to time as well as considering the Board diversity policy. The Governance and Nominating Committee may use the services of outside consultants in searching for or doing background checks on candidates. The Governance and Nominating Committee maintains a list of potential Directors who meet the established criteria and review such list as needed to track progress and identify suitable candidates. Board members, many of whom serve on other corporate boards, are encouraged to submit names. As requested by the Governance and Nominating Committee, the Chair, Vice-Chair and CEO, as well as any other Directors the Committee deems appropriate, interviews the candidates. Following receipt of the reports of the Chair, the Vice-Chair and the CEO as to such interviews, the Governance and Nominating Committee then makes such recommendations as it deems appropriate to the Board. The Board relied on this succession planning process to assist in the recruitment of Ms. Andrews, Mr. Anton, Ms. Paish, Ms. Slaski and Ms. Stuart to the Board during 2021 and 2022. The Human Resources Committee oversees succession planning for our CEO, with support from the Chair of the Board and the advice and recommendation of the Board. The Human Resources Committee also supports the CEO’s succession planning for our Company’s senior management team. At least annually, the Human Resources Committee reviews and approves the succession āç¨îĈËõĄďÒÀL¨î¼õďÒÀĄíÀíµÀĄĈõËďÒÀõíā¨îĦɉĈĈÀîÕõĄí¨î¨ÌÀíÀîďďÀ¨í¨î¼ĈāÀ¶Õŵ¶¼ÀğÀçõāíÀîďāç¨îĈ¨î¼¶¨ĄÀÀĄ planning for potential successors.

53 TELUS International | 2023 Information Circular It is the responsibility of the Governance and Nominating Committee to regularly evaluate the effectiveness and contribution of the Board, the Chair and Vice-Chair of the Board and all Committees and their chairs. The Governance and Nominating Committee is responsible to conduct an evaluation, either directly or through the CLO, and then reports the results to the Board. If deemed appropriate, the Governance and Nominating Committee may elect to engage a third party to provide expertise on and to assist with the coordination of the evaluation. This process allows the Company to evaluate the mechanism in place for the Board and Committees to operate effectively, identify opportunities to enhance and maintain best corporate practices, meet regulatory requirements and develop strategies for recruiting and succession planning. To conduct and document this evaluation, the Governance and Nominating Committee approves a questionnaire that is completed by each Director. Through these questionnaires, each Director provides their evaluation of the performance of: (1) the Board as a whole; (2) each Committee; (3) each Committee chair, and (4) each Director. The CLO is tasked with reviewing the results of these questionnaires and providing them to the Vice-Chair, with attribution to the originating Directors, except that, in the case of the Chair and the Vice-Chair, results are provided to the chair of the Governance and Nominating Committee. When the results are provided to the Chair, the Vice-Chair or the chair of the Governance and Nominating Committee, each Director may elect to have all or part of their comments included without attribution. However, in all cases, the subsequent feedback to the Governance and Nominating Committee and the Board are given without attribution. To provide a broader scope to our evaluation, the Governance and Nominating Committee also approves a questionnaire that is completed by all members of the Company’s senior management team who have regular interaction with the Board or its Committees. The purpose of this questionnaire is to provide an evaluation of the overall effectiveness of the Board from the perspective of the senior management team and consider how the Board and management support one another and how their relationship can be improved. The CLO is tasked with reviewing these results and providing them to the Chair and Vice-Chair of the Board, without attribution to any member of the senior management team. The Chair of the Board is then required to conduct separate interviews with each Director to advise of the results of this evaluation and then report on key themes and recommendations to the Governance and Nominating Committee and the Board. These results can then be used by the Chair of the Board to create a set of Board goals and objectives to address matters raised during the evaluation. In addition to our assessment process, the Governance and Nominating Committee conducts an annual review of the skills of each íÀíµÀĄõËďÒÀõ¨Ą¼ǿÕî¶çĔ¼ÕîÌ¨Ì¨ā¨î¨çĦĈÕĈǿ¨î¼í¨äÀĈĄÀ¶õííÀî¼¨ďÕõîĈďõďÒÀõ¨Ą¼ÕîďÒÀÀğÀîď¨îĦÌ¨āĈ¨ĄÀÕ¼ÀîďÕŵÀ¼Ǿ In accordance with the Board Policy Manual, each non-management Director appointed to the Board is required to tender his or her resignation after serving 15 years on the Board. The Governance and Nominating Committee will consider such resignation and has the discretion to recommend to the Board that the term of the resigning Director be extended for such period as the Governance and Nominating Committee deems appropriate, if in our best interest to do so. Our Board has no mandatory retirement age. Our Governance and Nominating Committee is responsible for reviewing the composition of our Board to ensure that it is composed of members containing the appropriate skills and expertise to advise us. Our Governance and Nominating Committee is expected to conduct a process for the assessment of our Board, each Committee and each Director regarding his, her or its effectiveness and performance, and to report evaluation results to our Board.

We also continue to drive high levels of performance by setting ambitious targets. The Human Resources Committee of the Company’s Board of Directors takes an approach to compensation that is both market-based and performance-based. The primary focus of the Human Resources Committee is to maintain an executive compensation program that supports the achievement of three objectives: To meet the three objectives of our compensation program, we apply the following six principles: „ ;ÀËËXĔĄÕďďǿXĄÀĈÕ¼Àîď¨î¼ÒÕÀËĥÀ¶ĔďÕğÀLËŵ¶ÀĄȬLȭȁ „ w¨îÀĈĈ¨=¨îĔǿÒÕÀË&Õî¨î¶Õ¨çLËŵ¶ÀĄȬ&Lȭȁ „ E¨ĄÕ¨X¨Ą¼ÀÀǿÒÕÀËõííÀĄ¶Õ¨çLËŵ¶ÀĄȬLȭȁ „ E¨ĄÕçĦîgĦËďÕîÌǿ_ÀîÕõĄwÕ¶ÀXĄÀĈÕ¼Àîď¨î¼ÒÕÀËõĄāõĄ¨ďÀLËŵ¶ÀĄȬLȺ-[Lȭȁ¨î¼ „ EÕ¶Ò¨Àç[ÕîÌí¨îǿÒÕÀË0îËõĄí¨ďÕõîLËŵ¶ÀĄȬ0LȭǾ „ to advance our business strategy; „ ďõÀîÒ¨î¶ÀõĔĄÌĄõĠďÒ¨î¼āĄõŵď¨µÕçÕďĦȁ¨î¼ „ to attract and retain the key talent necessary to achieve our business objectives. 1. We pay for performance An NEO’s compensation is based on the NEO’s personal performance, together with corporate performance and position within a range determined with reference to market compensation data. Linking executive pay to actual performance ensures that executive compensation is aligned with the creation of shareholder value. 2. We promote sound risk-taking Our executive compensation program incorporates many elements that are intended to ensure our compensation practices do not encourage excessive or inappropriate risk-taking. Below are some of the governance practices, policies and inherent design elements of our executive compensation program that help manage and mitigate risk in executive compensation: Overview Key compensation principles 58 Executive compensation

In connection with our initial public offering, our Board of Directors adopted the 2021 Omnibus Long-Term Incentive Plan (2021 LTIP), under which it granted equity awards to our NEOs at the initial public offering price. The 2021 LTIP is also used to grant annual long-term incentive awards, or LTIs. LTIs for performance year 2022, granted in the form of restricted share units (RSUs) and performance share units (PSUs), as well as grants of RSUs and options (Options) that were granted in connection with and prior to our initial public offering, result in a laddered vesting schedule for each award, rather than one-time vesting of all õĔďĈď¨î¼ÕîÌ¨Ġ¨Ą¼Ĉõî¨ĈāÀ¶ÕŵÀ¼¼¨ďÀďÒ¨ďÌÀîÀĄ¨ççĦĄÀĈĔçďĈÕîç¨ĄÌÀĄǿĈāõĄ¨¼Õ¶ĈÀďďçÀíÀîďĈǾgÒÀ?g0¨Ġ¨Ą¼Ĉ¨ĄÀƉƈƈāÀĄ¶Àîď equity-settled. For information about the 2021 LTIP and equity compensation programs that we implemented in connection with our initial public offering, please see “Equity Compensation Plans”. 4. We reward contribution Our approach to executive compensation is both market-based and performance-based. LTI grant levels have historically been performance-differentiated and are based on an executive’s in-year performance and future potential. We consider this performance-based approach to granting LTIs to be a best practice, instead of granting LTIs based on market benchmarks only. 5. We align compensation with corporate strategy To align executive compensation with our corporate strategy, we make a direct link between an executive’s pay and the executive’s performance against the achievement of our corporate objectives. The CEO and the other NEO’s annual performance bonuses are evaluated through assessing the Company’s performance, which is based on a combination of corporate scorecards, and individual performance. Performance bonus metrics are part of a multi-year business plan and are aligned with our longer-term goals. 50 per cent of our 2022 LTI awards took the form of PSUs to align management with shareholders’ interests while incentivizing management to achieve performance targets based on corporate performance objectives tied to earnings per share and revenue growth. The other 50% of our 2022 LTI awards are in the form of RSUs that are subject to service-vesting conditions to incentivize management retention. 6. We align our pay practices across the organization Our pay practices are aligned across the organization. We also use the following methodologies in considering equitable compensation: „ bonus calculations include a mix of Company and individual performance metrics for executives, as well as all team members; „ overall annual increases to base salary for the executives are relatively aligned with increases to base salary for positions below the executive level; „ í¨ďÀĄÕ¨ççĦõĄĈÕÌîÕŵ¶¨îďçĦÕî¶ĄÀ¨ĈÀ¼ĄÀĈāõîĈÕµÕçÕďĦÕî¨îĦďÀ¨ííÀíµÀĄɉĈĄõçÀ¨î¼ȍõĄ¨ĈĔµĈÀăĔÀîďāĄõíõďÕõîÕĈ¨¶¶õíā¨îÕÀ¼µĦ¨¶Ò¨îÌÀ in pay, as appropriate; and „ ¶õíāÀîĈ¨ďÕõî¼¨ď¨ǿ¨çõîÌĠÕďÒõďÒÀĄĄÀçÀğ¨îďË¨¶ďõĄĈǿĈĔ¶Ò¨ĈÕîďÀĄî¨çÀăĔÕďĦ¨î¼ĈďĄ¨ďÀÌÕ¶ĈÕÌîÕŵ¶¨î¶ÀõËďÒÀĄõçÀǿ¨ĄÀ¶õîĈÕ¼ÀĄÀ¼ďõ develop a base salary range and a total compensation target for all positions across the organization. 60

Members of the Human Resources Committee have a range of complementary skills in areas such as human resources, corporate governance, risk assessment, public company leadership and board experience, which enable them to make effective decisions on our compensation practices. Some of the Human Resources Committee members have served in executive capacities or on compensation committees with other public issuers and, through those roles, have acquired direct experience relevant to their responsibilities for reviewing and considering executive compensation. The diverse experience of the Human Resources Committee members also includes an extensive understanding of accounting considerations in the context of executive compensation and practices for attracting, developing and retaining talent. As of December 31, 2022, the members of the Human Resources Committee were Mr. Blair, who chairs the committee, Ms. Paish and Ms. Slaski.

2023 Information Circular | TELUS International Base salary methodology At-risk pay: annual performance bonus TELUS International performance bonus program At-risk incentive pay components During 2022, the Human Resources Committee considered and approved the CEO’s annual base salary. Mr. Blair, the Vice-Chair of the Board of Directors and the Chair of our Human Resources Committee, was delegated the authority by our Board of Directors to approve any changes in base salary for members of the executive leadership team. We set our base salary range midpoints at the 50th percentile of a comparator group. As part of its annual pay assessment for 2022, the Human Resources Committee reviewed competitive pay data prepared by the Compensation Consultant. We then made adjustments to individual base salaries that we considered appropriate to recognize the executives’ varying levels of responsibility, prior experience, breadth of knowledge, overall individual performance and internal equity, as well as the pay practices of companies in a comparator group. As required, pursuant to the Board Policy Manual, the Human Resources Committee has reviewed and approved the CEO’s compensation based on the Human Resources Committee’s assessment of the CEO’s performance. The annual performance bonus for NEOs is determined pursuant to the PBP. A summary of the terms of the PBP follows. Methodology The PBP is designed to reward the achievement of business objectives in the short-term by providing immediate income in cash.

The three-step process is described in further detail below. Step 1: Assess Company corporate performance as measured by the corporate scorecard results The Company’s corporate performance is measured through the results of our corporate scorecard, which is determined after the end of a performance year by rating the extent to which we have met or exceeded our targets for each metric set at the start of the ĦÀ¨ĄǾLĔĄƊƈƊƊíÀďĄÕ¶ĈíÀ¨ĈĔĄÀ¼¨¶ÒÕÀğÀíÀîďĈÕîďÒÀËõççõĠÕîÌ¨ĄÀ¨ĈȀgÀ¨íǿĔĈďõíÀĄĈ&ÕĄĈďǿ¨î¼XĄõŵď¨µçÀ'ĄõĠďÒˈËŵ¶ÕÀî¶ĦǾ_ÀÀ below table on the 2022 corporate scorecard metrics.

2023 Information Circular | TELUS International Step 2: Assess an executive’s individual performance The individual performance of each NEO is initially assessed by the CEO and is reviewed and approved by the Human Resources Committee. The individual performance of the CEO is reviewed and approved by the Human Resources Committee. The chair of the Human Resources Committee invites the Board of Directors’ members to provide their feedback regarding the CEO’s performance. Step 3: Calculate the annual performance bonus based on the above payout formula Based on an assessment and recommendation from the CEO, the Human Resources Committee reviews each NEO’s performance and determines an individual multiplier, and along with the related multiplier in the Company corporate balanced scorecards, approves the annual performance bonus under the PBP for each NEO using the formula in this section. The Human Resources Committee, with input from the Chair of the Board of Directors, assesses the personal performance of the CEO and his leadership. Based on this assessment, the Human Resources Committee determines an individual multiplier and, along with the related multiplier in the Company corporate balanced scorecard, approves the annual performance bonus under the PBP for the CEO, based on the formula in this section.

For each of our NEOs, individual performance is weighted at 30 per cent and Company corporate performance is weighted at 70 per cent; and for the CEO, individual performance is weighted at 20 percent and Company corporate performance is weighted at 80 per cent. In addition to Company corporate and individual performance, the Board of Directors has the discretion to adjust bonus payouts for any extraordinary circumstances or other factors, as it deems appropriate. At-risk pay: long-term incentives 2022 long-term incentives Our Human Resources Committee designed an executive compensation program to achieve the objectives described above under “Key Compensation Principles.” This includes the grant of annual equity awards by our Human Resources Committee, which are used to encourage an ownership culture and align management with stockholders’ interests. On March 21, 2022, our Human Resources Committee approved long-term performance incentive awards for our senior leaders, including our NEOs, which were granted under the 2021 LTIP. 50% of the equity granted to our senior leaders was in the form of RSUs and 50% of the equity granted to our senior leaders was in the form of PSUs. We believe the use of RSUs and PSUs align the compensation of these senior leaders with stockholders’ interests. The value recognized by individuals with respect to these awards will depend on the Company’s stock price performance and, in the case of the PSUs, if certain performance targets are met within the performance period, as described below. The number of RSUs and PSUs granted were calculated based on the closing price per g0ĈÒ¨ĄÀõîE¨Ą¶ÒƉƐǿƊƈƊƊõËʈƊƎǾƋƐǾgÒÀ[_lĈÌÀîÀĄ¨ççĦğÀĈďƊƍʫõîÀ¨¶ÒõËďÒÀŵĄĈďËõĔĄ¨îîÕğÀĄĈ¨ĄÕÀĈõËďÒÀÌĄ¨îď¼¨ďÀǿĈĔµáÀ¶ď to continued employment through each applicable vesting date.

In the event of a termination without cause, the holder will be entitled to a prorated portion of the award, calculated based on the amount of service provided during the applicable performance period assuming target performance. The individual grant values for each of our NEOs, including the threshold, target and maximum payout of PSUs, are set forth in the “Grants of Plan-Based Awards Table”, below. „ 60 per cent of the PSUs will be earned based on the Company’s earnings per share compound annual growth rate during the performance period, which we refer to as EPS Growth CAGR; and „ 40 per cent of the PSUs will be earned based on the Company’s organic revenue compound annual growth rate during the performance period, calculated pursuant to IFRS, which we refer to as Organic Revenue Growth CAGR. 66

The Human Resources Committee generally looks to position the value of target TDC to be competitive with the 50th percentile of comparable companies, with exceptions made based on the Human Resources Committee’s analysis of key factors including the NEO’s performance and tenure. In assessing competitive compensation levels and practices, the Human Resources Committee reviewed and compared compensation to executives at a peer group of companies.

2023 Information Circular | TELUS International Share usage Minimum vesting Treatment of awards upon a participant’s termination of employment Clawback Amendment of the 2021 LTIP The number of shares remaining available for issuance will be reduced by the number of shares subject to outstanding awards and, for awards that are not denominated by shares, by the number of newly-issued shares actually delivered upon settlement or payment of the award. For purposes of determining the number of shares that remain available for issuance under the 2021 LTIP, the number of shares related to an award to be settled in newly-issued shares granted under the 2021 LTIP that terminates by expiration, forfeiture, cancellation or otherwise without the issuance of the shares, are settled through the delivery of market- purchased shares or the delivery of consideration other than shares (including cash), will be available again for grant under the 2021 LTIP. However, where awards providing for settlement solely in newly-issued shares have been surrendered for cancellation, in consideration of the satisfaction of the payment of the purchase price or tax withholding obligations related to the Award, the shares underlying such award will not be available again for grant under the 2021 LTIP. Except for deferred share units granted to Directors, all awards are subject to a minimum time-based vesting restriction or performance period, as applicable, of not less than one year. The minimum vesting requirements do not apply to (1) acceleration in the event of a termination of employment or termination of directorship on or following a change in control, or due to retirement, death or disability; (2) a substitute award subject to time-based vesting restrictions no less than the restrictions of the awards being replaced; and (3) awards involving an aggregate number of shares not in excess of 5 per cent of the total shares authorized for issuance under the 2021 LTIP. The Human Resources Committee may determine, at or after the time of grant, the terms and conditions that apply to any award upon ¨ā¨ĄďÕ¶Õā¨îďɉĈďÀĄíÕî¨ďÕõîõËÀíāçõĦíÀîďĠÕďÒďÒÀõíā¨îĦ¨î¼ÕďĈ¨ËŵçÕ¨ďÀĈǾ_ĔµáÀ¶ďďõ¨āāçÕ¶¨µçÀç¨ĠĈǿĄĔçÀĈ¨î¼ĄÀÌĔç¨ďÕõîĈǿ¨Ĉ well as the minimum vesting period of one year, in connection with a participant’s termination, the Human Resources Committee has the discretion to accelerate the vesting, exercisability or settlement of, to eliminate the restrictions and conditions applicable to, or to extend the post-termination exercise period of an outstanding award. All awards are subject to clawback or recoupment pursuant to applicable laws, rules, regulations or Company policy as in effect from time to time. Our Board of Directors has the right to amend the 2021 LTIP and any award made under the 2021 LTIP at any time for any reason or no reason; provided that no amendment may adversely affect in any material way any award previously granted under the 2021 LTIP without the written consent of the participant, subject to certain conditions described in the 2021 LTIP. However, shareholder approval will be obtained for any amendment that (1) increases the number of shares reserved for issuance, except in connection with a corporate transaction, (2) increases or removes the limits on shares issuable or issued to insiders, (3) involves a reduction in the exercise price of an option or grant price of a share appreciation right, except in connection with a corporate transaction, (4) extends the term of an award beyond its original expiry date, except for an extension of up to ten business days if the expiry is occurring at the time of a trading blackout period, (5) permits transfers to persons other than permitted transferees or for estate settlement purposes or (6) deletes or reduces the range of amendments requiring shareholder approval. Unless provided otherwise in an agreement or by the Human Resources Committee prior to the date of the change in control, the 2021 LTIP provides that in the event of a change in control: „ outstanding awards may be assumed by, or similar awards be substituted by, the successor in a transaction; „ if the participant’s employment with a successor terminates in connection with or within one year following the change in control ËõĄ¨îĦĄÀ¨ĈõîõďÒÀĄďÒ¨î¨îÕîğõçĔîď¨ĄĦďÀĄíÕî¨ďÕõîµĦ¨ĈĔ¶¶ÀĈĈõĄËõĄɆ¶¨ĔĈÀɇȬ¨ĈĈĔ¶ÒďÀĄíÕĈ¼ÀŵîÀ¼ÕîďÒÀ¨āāçÕ¶¨µçÀ¨Ġ¨Ą¼ agreement), all of the participant’s awards will become vested in full or deemed earned in full (assuming the target performance goals provided under the award were met, if applicable) effective on the date of the participant’s termination of employment.

The shares to be issued under the 2021 ESPP may be authorized but unissued shares or may be reacquired shares, including shares purchased on the open market. The 2021 ESPP is administered by the Human Resources Committee or such other Committee appointed by the Board of Directors to administer the 2021 ESPP. The plan administrator may delegate its administrative responsibilities and powers under the 2021 ESPP to any employees or a group of employees. The plan administrator may designate separate offerings under the 2021 ESPP, the terms õËĠÒÕ¶ÒîÀÀ¼îõďµÀÕ¼ÀîďÕ¶¨çǿÕîĠÒÕ¶ÒÀçÕÌÕµçÀÀíāçõĦÀÀĈõËõîÀõĄíõĄÀā¨ĄďÕ¶Õā¨ďÕîÌĈĔµĈÕ¼Õ¨ĄÕÀĈ¨î¼¨ËŵçÕ¨ďÀĈĠÕççā¨ĄďÕ¶Õā¨ďÀǿ even if the dates of the applicable offering periods in each such offering are identical; provided that the terms of participation are the same within each separate offering as determined under Section 423 of the Code. The plan administrator may also adopt sub-plans, appendices, rules and procedures relating to the operation and administration of the 2021 ESPP to facilitate participation in the 2021 ESPP by employees who are foreign nationals or employed outside the U.S. To the extent any sub-plan is inconsistent with the requirements of Section 423 of the Code, it will be considered part of the Non-Section 423 Component. Under the 2021 ESPP, participating employees are granted rights to purchase subordinate voting shares at a price equal to at least 85 per cent of the share’s fair market value on the purchase date (unless and until such percentage is changed by the plan administrator prior to the commencement of the enrollment process for the applicable purchase interval). An eligible employee will be able to elect to participate in an offering period under the 2021 ESPP by authorizing after-tax payroll deductions from gross wages on or before the start date of such offering period or such other payments as may be permitted. Offering periods will commence at quarterly intervals and have a maximum duration of six months and a minimum duration of up to three months unless otherwise determined by the plan administrator prior to the start of such offer period (but in no event may an offering period exceed 24 months). Employees may generally authorize contributions in multiples of 1 per cent, up to a maximum of 15 per cent, of gross wages to purchase shares under the 2021 ESPP. On the start date of each offering period in which a participant is enrolled, the participant will be granted a separate purchase right for such an offering period. The purchase will be effected by applying the participant’s contributions for the purchase interval ending on such purchase date to the purchase of whole or fractional shares. No participant may purchase more than $25,000 of subordinate voting shares (using the fair market value of the shares on the date the purchase rights are granted) under the 2021 ESPP (and any õďÒÀĄÀíāçõĦÀÀĈÒ¨ĄÀāĔĄ¶Ò¨ĈÀāç¨îõËďÒÀõíā¨îĦõĄ¨î¨ËŵçÕ¨ďÀȭāÀĄ¶¨çÀî¼¨ĄĦÀ¨ĄǾ We adopted an employee share purchase plan (2021 ESPP), under which our eligible employees and the eligible employees of our ā¨ĄďÕ¶Õā¨ďÕîÌĈĔµĈÕ¼Õ¨ĄÕÀĈ¨î¼¨ËŵçÕ¨ďÀĈí¨ĦÀçÀ¶ďďõ¨¶ăĔÕĄÀõĔĄĈĔµõĄ¼Õî¨ďÀğõďÕîÌĈÒ¨ĄÀĈ¨ď¨¼ÕĈ¶õĔîďĔāďõƉƍāÀĄ¶ÀîďËĄõíďÒÀ prevailing fair market value.

Contributions will continue with respect to any gross wages received by a participant while he or she is on an approved leave of absence unless the participant elects to withdraw from the offering period. If a participant transfers employment from the Company or any participating subsidiary for the Section 423 Component to a participating subsidiary for the Non-Section 423 Component, he or she will immediately cease to participate in the Section 423 Component. However, any contributions made for the offering period in which such transfer occurs will be transferred to the Non-Section 423 Component, and such participant will immediately join the then-current offering under the Non-Section 423 Component upon the same terms and conditions in effect for his or her participation in the 2021 ESPP. The plan administrator may establish different rules to govern transfers of employment between subsidiaries participating in the Section 423 Component and the Non-Section 423 Component, consistent with the applicable requirements of Section 423 of the Code. If a change in control of the Company occurs, each outstanding purchase right will automatically be exercised immediately prior to the effective date of such change in control. The purchase price applicable for the purchase interval in which the change in control occurs will be equal to 85 per cent of the fair market value per share of our subordinate voting shares immediately prior to the effective date of such change in control. However, participants will, following the receipt of notice from us of a change in control, have the right to terminate their outstanding purchase rights prior to the effective date of such change in control. Furthermore, the plan administrator may terminate any outstanding purchase rights prior to the effective date of a change in control, in which case all payroll deductions for the purchase interval in which such contributions are terminated will be promptly refunded. The Board of Directors has the right to terminate, suspend or amend the 2021 ESPP at any time, generally to become effective immediately following the close of any purchase interval, subject to applicable laws and the requirements of any stock exchange or governmental or regulatory body (including any requirement for shareholder approval).
