1. Condensed interim consolidated financial statements

(a)     Basis of presentation

The notes presented in our condensed interim consolidated financial statements include only significant events and transactions and are not fully inclusive of all matters normally disclosed in our annual audited financial statements; thus, our interim consolidated financial statements are referred to as condensed. Our financial results may vary from period to period during any fiscal year. The seasonality in our business, and consequently, our financial performance, mirrors that of our clients. Our revenues are typically higher in the third and fourth quarters than in other quarters, but this can vary if there are material changes to our clients’ operating environment, such as potential impacts of a recession and our clients’ response to those impacts, or material changes in the foreign currency rates that we operate in.

These condensed interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2023, and are expressed in United States dollars and follow the same accounting policies and methods of their application as set out in our audited consolidated financial statements for the year ended December 31, 2023. The generally accepted accounting principles that we use are International Financial Reporting Standards as issued by the International Accounting Standards Board (IFRS-IASB). Our condensed interim consolidated financial statements comply with International Accounting Standard 34, Interim Financial Reporting and reflect all adjustments (which are of a normal recurring nature) that are, in our opinion, necessary for a fair statement of the results for the interim periods presented.

These condensed interim consolidated financial statements as at and for the three-month period ended March 31, 2024 were authorized by our Board of Directors for issue on May 9, 2024.

(b)    Accounting policy developments

Initial application of standards, interpretations and amendments to standards and interpretations

In May 2023, the International Accounting Standards Board issued International Tax Reform – Pillar Two Model Rules (Amendments to IAS 12), which amended IAS 12, Income Taxes. The amendments provide, and we use, temporary relief from accounting for deferred income taxes arising from the Organisation for Economic Co-operation and Development’s Pillar Two model rules (such rules ensuring that large multinational corporations would be subject to a minimum 15% income tax rate in every jurisdiction in which they operate). As different jurisdictions are expected to implement the OECD rules at different speeds and at different points in time, the amendments are intended to help ensure consistency within, and comparability across, financial statements. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. We have assessed the impacts of the amended standard, and our financial disclosure was not materially affected by the application of the amendments.

Standards, interpretations and amendments to standards and interpretations not yet effective and not yet applied

In April 2024, the International Accounting Standards Board issued IFRS 18, Presentation and Disclosure in the Financial Statements, which sets out the overall requirements for presentation and disclosures in the financial statements. The new standard will replace IAS 1, Presentation of Financial Statements. Although much of the substance of IAS 1, Presentation of Financial Statements, will carry over into the new standard, the new standard incrementally will:

•With a view to improving comparability amongst entities, require presentation in the statement of operations of a subtotal for operating profit and a subtotal for profit before financing and income taxes (both subtotals as defined in the new standard);

•Require disclosure and reconciliation, within a single financial statement note, of management-defined performance measures (e.g. measures and/or ratios that currently and commonly would be considered to be non-GAAP financial measures, supplementary financial measures and/or non-GAAP ratios) that are used in public communications to share management’s views of various aspects of an entity’s performance and which are derived from the statements of income and other comprehensive income;

•Enhance the requirements for aggregation and disaggregation of financial statement amounts; and

•Require limited changes to the statement of cash flows, including elimination of options for the classification of interest and dividend cash flows.

The new standard is effective for annual reporting periods beginning on or after January 1, 2027, with earlier adoption permitted. We are currently assessing the impacts of the new standard; while there will be a shift of where a number of the management-defined performance measures are disclosed and reconciled (primarily a shift from management’s discussion and analysis to the financial statements), we do not expect that the totality of our financial disclosure will be materially affected by the application of the new standard.

2. Capital structure financial policies

Our objective when managing capital is to maintain a flexible capital structure that optimizes the cost and availability of capital at acceptable risk levels.

In the management of capital and in its definition, we include owners’ equity (excluding accumulated other comprehensive income), long-term debt (including long-term credit facilities and any hedging assets or liabilities associated with our long-term debt, net of amounts recognized in accumulated other comprehensive income and excluding lease liabilities) and cash and cash equivalents. We manage capital by monitoring the financial covenants in our credit facility (Note 13—Long-term debt).

We manage our capital structure and make adjustments to it in light of changes in economic conditions and the risk characteristics of our business. In order to maintain or adjust our capital structure, we may issue new shares, issue new debt with different terms or characteristics, which may be used to replace existing debt, or pay down our debt balance with cash flows from operations.

3. Revenue

We earn revenue pursuant to contracts with our clients, who operate in various industry verticals. The following presents our earned revenue disaggregation for our five largest industry verticals for the following periods:

	Three months
Periods ended March 31 (millions)	2024		2023
Tech and Games	$	278	$	287
Communications and Media	160		153
eCommerce and FinTech	68		79
Healthcare	49		40
Banking, Financial Services and Insurance	36		44
All others1	66		83
	$	657	$	686

1.All others includes, among others, travel and hospitality, energy and utilities, retail, and consumer packaged goods industry verticals.

We serve our clients, who are primarily domiciled in North America, from multiple delivery locations across various geographic regions. In addition, our TIAI Data Solutions business has clients that are largely supported by crowdsourced contractors that are globally dispersed and not limited to the physical locations of our delivery centres. The following table presents our earned revenue disaggregated by geographic region, based on location of our delivery centre or where service was provided, for the following periods:

Central America and others1	120		106
	$	657	$	686

1.Others includes South America and Africa geographic regions.

4. Share-based compensation

(a)    Restricted share unit plan

We grant restricted share units (RSUs) and performance restricted share units (PSUs), which are accounted for as equity-settled, as this is the expected manner of their settlement when granted. All awards granted under the restricted share unit plan are nominally equal in value to one TELUS International subordinate voting share. Our PSU grants largely have the same features as our RSUs, but have a variable payout (0% — 200%) that depend upon the achievement of operating performance targets (non-market conditions), or total shareholder return on TELUS International subordinate voting shares relative to an international peer group of customer experience and digital IT services companies (market conditions). The grant-date fair value of our PSUs affected by the achievement of non-market conditions equals the share price of the corresponding TELUS International subordinate voting share as of the grant date. Reflecting a variable payout, we estimate the grant-date fair value of our PSUs affected by the relative total shareholder return performance condition using a Monte Carlo simulation.

The following table presents a summary of the activity related to our restricted share unit plan:

	Three months
	Number of units		Weighted average grant-date fair value
Period ended March 31, 2024	Non-vested	Vested
Outstanding, beginning of period	2,615,746	—	$	21.36

Forfeited	(203,821)	—	$	23.71
Outstanding, March 31, 2024	5,238,584	—	$	13.38

1.During the three-month period ended March 31, 2024, 473,474 RSUs were exercised and settled with 282,672 subordinate voting shares issued from treasury and $2 million in withholding taxes paid.

As at March 31, 2024, the outstanding restricted share units comprised of 3,976,440 RSUs, 988,023 PSUs (non-market conditions), and 274,121 PSUs (market conditions).

(b)    Share option award plan

We grant share option awards, which are accounted for as equity-settled, as this is the expected manner of their settlement when granted. Share option awards grant the right to the employee recipient to purchase and receive a subordinate voting share of TELUS International for a pre-determined exercise price, and are generally exercisable for a period of ten years from the date of grant. The following table presents the activity related to our share option award plan:

	Three months
	Number of share option award units		Weighted average exercise price
Period ended March 31, 2024	Non-vested	Vested
Outstanding, beginning of period	220,100	2,316,683	$	10.39
Vested	(110,050)	110,050	$	25.00
Forfeited	(20,962)	(62,887)	$	25.00
Outstanding, March 31, 20241	89,088	2,363,846	$	9.89
Exercisable, March 31, 2024	—	2,363,846	$	9.32

1.The exercise price for options outstanding as at March 31, 2024 ranged from $4.87 to $8.95 for 2,096,582 options with a weighted-average remaining contractual life of 2.7 years, and $25.00 for 356,352 options with a weighted-average remaining contractual life of 6.9 years.

Other	—		—	%	(1)		(8.3)	%
Income tax expense (recovery)	$	9	24.3	%	$	(2)	(16.7)	%

We are subject to the global minimum top-up income tax under Pillar Two tax legislation. The top-up income tax relates primarily to our operations in Bulgaria and Ireland, where the statutory income tax rate is 10% and 12.5%, respectively. During the three-month period ended March 31, 2024, the Company recognized a current income tax expense of $1 million related to the Pillar Two tax.

We have applied a temporary mandatory relief from deferred income tax accounting for the impacts of the top-up income tax and it is recognized as a current income tax in the period it is incurred.

As at March 31, 2024, both Bulgaria and Ireland have enacted global minimum income tax into domestic tax legislation effective January 1, 2024. As a result, our Bulgarian and Irish subsidiaries will be liable for the top-up income tax rather than the ultimate Canadian parent company.

7. Earnings per share

(a)Basic earnings per share

Basic earnings per share is calculated by dividing net income by the total weighted average number of equity shares outstanding during the period.

	Three months
Periods ended March 31 (millions except earnings per share)	2024		2023
Net income for the period	$	28	$	14
Weighted average number of equity shares outstanding	274		273
Basic earnings per share	$	0.10	$	0.05

(b)Diluted earnings per share

Diluted earnings per share is calculated to give effect to the potential dilutive effect that could occur if additional equity shares were assumed to be issued under securities or instruments that may entitle their holders to obtain equity shares in the future, which include share-based compensation awards (see Note 4—Share-based compensation for additional details) and provision for written put options (see Note 14(c)—Intangible assets and goodwill—Business acquisitions in our Annual Report and Note 12—Provisions for additional details). The number of additional shares for inclusion in the diluted earnings per share calculation was determined using the treasury stock method and, for our provision for written put options, the if-converted method.

	Three months
Periods ended March 31 (millions except earnings per share)	2024		2023
Net income for the period	$	28	$	14

Diluted earnings per share	$	0.05	$	0.05

During the three-month periods ended March 31, 2024, 356,352 Share Options were anti-dilutive and excluded from the calculation of diluted earnings per share (March 31, 2023 - 440,201).

Total	$	471	$	498

The following table presents an analysis of the age of customer accounts receivable. Any late payment charges are levied at a negotiated rate on outstanding non-current customer account balances.

As at (millions)	March 31, 2024		December 31, 2023

	238		276
Accounts receivable – unbilled	204		194
Other receivables	29		28
Total	$	471	$	498

We maintain allowances for lifetime expected credit losses related to doubtful accounts. Current economic conditions (including forward-looking macroeconomic data), historical information (including credit agency reports, if available), reasons for the accounts being past due and line of business from which the customer accounts receivable arose are all considered when determining whether to make allowances for past-due accounts. The same factors are considered when determining whether to write off amounts charged to the allowance for doubtful accounts against the customer accounts receivable. The doubtful accounts expense is calculated on a specific-identification basis for customer accounts receivable over a specific balance threshold and on a statistically derived allowance basis for the remainder. No customer accounts receivable balances are written off directly to bad debt expense.

The following table presents a summary of the activity related to our allowance for doubtful accounts:

9. Financial instruments

General

The carrying values of cash and cash equivalents, due from or to affiliated companies, accounts receivable, accounts payable and accrued liabilities and certain provisions approximate their fair values due to the immediate or short-term maturity of these financial instruments. Our long-term debt, measured at amortized cost, approximates fair value as they bear interest at applicable market rates.

The fair values of the derivative financial instruments we use to manage our exposure to currency risks are estimated based upon quoted market prices in active markets for the same or similar financial instruments or on the current rates offered to us for financial instruments of the same maturity, as well as discounted future cash flows determined using current rates for similar financial instruments subject to similar risks and maturities (such fair value estimates being largely based on the European euro: US$ and Philippine peso: US$ forward exchange rates as at the statement of financial position dates).

Derivative

The derivative financial instruments that we measure at fair value on a recurring basis subsequent to initial recognition are as set out in the following table; all such items use significant other observable inputs (Level 2) for measuring fair value at the reporting date.

		March 31, 2024							December 31, 2023

We have a credit facility secured by our assets with a syndicate of financial institutions, which includes TELUS Corporation as a lender, maturing on January 3, 2028. The credit facility is comprised of an $800 million revolving credit facility and an amortizing $1.2 billion term loan. As at March 31, 2024, the revolving credit facility and term loan had an effective interest rate of 7.43% (December 31, 2023 - 7.46%).

1.We have entered into a receive-floating interest rate, pay-fixed interest rate exchange agreement that effectively converts a portion of our interest obligations on the debt to a fixed rate of 3.52% plus applicable margins.

The credit facility bears interest at prime rate, U.S. dollar base rate, a bankers’ acceptance rate or Term Secured Overnight Financing Rate (SOFR) (all such terms as used or defined in the credit facility) plus applicable margins. The credit facility contains customary representations, warranties and covenants, including two financial quarter-end ratio tests. Net Debt to Adjusted EBITDA ratio, both measures as defined in our credit agreement, must not exceed 3.75:1.00 for each quarter in fiscal 2024 and 3.25:1.00 subsequently. The Adjusted EBITDA to Debt Service (interest and scheduled principal repayment) ratio must not be less than 1.50:1.00, all as defined in the credit facility. If an acquisition with an aggregate cash consideration in excess of $250 million occurs in any twelve-month period, the maximum permitted Net Debt to Adjusted EBITDA ratio per credit agreement may be increased by 0.50:1.00 and shall return to the then applicable Net Debt to Adjusted EBITDA ratio after eight fiscal quarters.

The term loan of the credit facility is subject to an amortization schedule requiring that 1.25% of the original principal advanced be repaid each quarter with the balance due at maturity of the amended credit facility on January 3, 2028.

As at March 31, 2024, we were in compliance with all financial covenants, financial ratios and all of the terms and conditions of our credit facility and long-term debt agreement.

15. Contingent liabilities

(a)Indemnification obligations

In the normal course of operations, we provide indemnification in conjunction with certain transactions. The terms of these indemnification obligations range in duration. These indemnifications would require us to compensate the indemnified parties for costs incurred as a result of failure to comply with contractual obligations or litigation claims or statutory sanctions or damages that may be suffered by an indemnified party. In some cases, there is no maximum limit on these indemnification obligations. The overall maximum amount of an indemnification obligation will depend on future events and conditions and therefore cannot be reasonably estimated. Where appropriate, an indemnification obligation is recorded as a liability. Other than obligations recorded as liabilities at the time of such transactions, if applicable, historically we have not made significant payments under these indemnifications. As at March 31, 2024, we had no liability recorded in respect of indemnification obligations (December 31, 2023 - $nil).

(b)Claims and lawsuits

We are party to various legal proceedings and claims that arise in the ordinary course of business. The ultimate outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against us for amounts in excess of management's estimates of loss, or if any outcome becomes more likely than not and estimable, our results of operations and financial condition could be adversely affected.
