SEPTEMBER 30, 2025

TELUS Corporation is one of Canada’s largest telecommunications companies, providing a wide range of technology solutions, which include: mobile and fixed voice and data telecommunications services and products; healthcare services, software and technology solutions (including employee and family assistance programs and benefits administration); agriculture and consumer goods services (software, data management and data analytics-driven smart-food chain and consumer goods technologies); and digital experiences. Data services include: internet protocol; television; hosting, managed information technology and cloud-based services; and home and business security and automation.

TELUS Corporation was incorporated under the Company Act (British Columbia) on October 26, 1998, under the name BCT.TELUS Communications Inc. (BCT). On January 31, 1999, pursuant to a court-approved plan of arrangement under the Canada Business Corporations Act among BCT, BC TELECOM Inc. and the former Alberta-based TELUS Corporation (TC), BCT acquired all of the shares of BC TELECOM Inc. and TC in exchange for Common Shares and Non-Voting Shares of BCT, and BC TELECOM Inc. was dissolved. On May 3, 2000, BCT changed its name to TELUS Corporation and in February 2005, TELUS Corporation transitioned under the Business Corporations Act (British Columbia), successor to the Company Act (British Columbia). TELUS Corporation maintains its registered office at Floor 5, 510 West Georgia Street, Vancouver, British Columbia, V6B 0M3.

The terms “TELUS”, “we”, “us”, “our” or “ourselves” refer to TELUS Corporation and, where the context of the narrative permits or requires, its subsidiaries. Our principal subsidiaries are: TELUS Communications Inc., in which, as at September 30, 2025, we have a 100% equity interest; TELUS Health Inc., in which, as at September 30, 2025, we have a 100% equity interest; and TELUS International (Cda) Inc. (d.b.a. TELUS Digital Experience), in which, as at September 30, 2025, we have a 57.0% equity interest, and as at November 7, 2025, we have a 100% equity interest, as discussed further in Note 28(b).

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 condensed interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2024.

Our condensed interim consolidated financial statements are expressed in Canadian dollars and follow the same accounting policies and methods of their application as set out in our consolidated financial statements for the year ended December 31, 2024, other than as set out in Note 2(a). The generally accepted accounting principles that we use are International Financial Reporting Standards as issued by the International Accounting Standards Board (IFRS® Accounting Standards) and Canadian generally accepted accounting principles. 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 consolidated financial statements for the three-month and nine-month periods ended September 30, 2025, were authorized by our Board of Directors for issue on November 7, 2025.

General

We apply hedge accounting to the financial instruments used to establish: designated currency hedging relationships for certain U.S. dollar-denominated future purchase commitments and debt repayments; and, designated electrical power purchase price hedging relationships.

The purpose of hedge accounting, in respect of our designated hedging relationships, is to ensure that counterbalancing gains and losses are recognized in the same periods. We have chosen to apply hedge accounting, as we believe that it more faithfully depicts the economic substance of the underlying transactions.

The application of hedge accounting requires a high correlation (indicating effectiveness) in the offsetting changes in the risk-associated values of the financial instruments (the hedging items) used to establish the designated hedging relationships and all, or a part, of the asset, liability or transaction with an identified risk exposure that we have taken steps to modify (the hedged items).

Hedge accounting – derivatives used to manage currency risk; derivatives used to manage interest rate risk

The anticipated effectiveness of designated hedging relationships is assessed at inception and their actual effectiveness is assessed for each subsequent reporting period. We consider a designated hedging relationship to be effective if the following critical terms match between the hedging item and the hedged item: the notional amount of the hedging item and the principal amount of the hedged item; maturity dates; payment dates; and interest rate index (if, and as, applicable).

Any ineffectiveness, such as arising from differences between the notional amount of the hedging item and the principal amount of the hedged item, or from a previously effective designated hedging relationship becoming ineffective, is reflected in the Consolidated statements of income and other comprehensive income as Financing costs if in respect of long-term debt and as Goods and services purchased if in respect of U.S. dollar-denominated future purchase commitments, as set out in Note 4(e).

Hedge accounting – derivatives use to manage other price risk (see Note 2(a))

The anticipated effectiveness of designated hedging relationships is assessed at inception (January 1, 2025, for virtual power purchase agreements entered into prior to fiscal 2025) and their actual effectiveness is assessed for each subsequent reporting period. We consider a virtual power purchase agreement designated hedging relationship to be effective if the following critical terms match between the hedging item and the hedged item: the variable nature-dependent electricity notional amount of the hedging item and the variable notional amount of the hedged item; maturity dates; and payment dates.

Any ineffectiveness, such as arising from differences between electricity consumed that is priced using the Alberta Interconnected Electrical System pool price, and that which is priced otherwise, or from a previously effective designated hedging relationship becoming ineffective, is reflected in the Consolidated statements of income and other comprehensive income as Goods and services purchased, as set out in Note 4(e).

Hedging assets and liabilities

In applying hedge accounting, a hedge value is recorded in the Consolidated statements of financial position representing the fair value of the hedging items. The net difference, if any, between amounts recognized in net income determination and amounts necessary to reflect the fair value of the designated cash flow hedging items recorded in the Consolidated statements of financial position is recognized as a component of Other comprehensive income, as set out in Note 11.

Inventories primarily consist of mobile handsets, parts and accessories, which totalled $363 million as at September 30, 2025 (December 31, 2024 – $528 million), and communications equipment held for resale. These inventories are valued at the lower of cost and net realizable value, with cost being determined on an average cost basis. Costs of goods sold for the three-month and nine-month periods ended September 30, 2025, totalled $0.6 billion (2024 – $0.6 billion) and $1.7 billion (2024 – $1.7 billion), respectively.

In accordance with the permitted transitional provisions, effective January 1, 2025, we have prospectively designated our pre-existing virtual power purchase agreements, which are contracts for differences, as held for hedging and have applied hedge accounting; this will have the effect of the net change in the unrealized forward element of our virtual power purchase agreements arising on or after January 1, 2025, being included in the determination of other comprehensive income. The transitional provisions did not permit retrospective designation of our pre-existing virtual power purchase agreements.

The effects on the consolidated statement of income and other comprehensive income line items are as set out in the following table.

The effects on the consolidated statement of changes in owners’ equity line items are as set out in the following table.

The effects on the consolidated statement of cash flows line items are as set out in the following table.

10 | September 30, 2025

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 limited shift of where a number of our management-defined performance measures are disclosed and reconciled (primarily a shift from management’s discussion and analysis to the financial statements) and where certain cash flows will be categorized in our statements of cash flows (primarily shifting interest paid from operating activities to financing activities), we do not expect that the totality of our financial disclosure will be materially affected by the application of the new standard.

General

Our objective when managing financial capital is to maintain a flexible capital structure that optimizes the cost and availability of capital at an acceptable level of risk. In our definition of financial capital, we include:

We manage our financial 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 financial capital structure, we may:

September 30, 2025 | 11

During 2025, our financial objectives, which are reviewed annually, were unchanged from 2024. We believe that our financial objectives support our long-term strategy.

We monitor financial capital utilizing a number of measures, including: net debt to earnings before interest, income taxes, depreciation and amortization (EBITDA*) – excluding restructuring and other costs ratio; coverage ratios; and dividend payout ratios.

Debt and coverage ratios

Net debt to EBITDA – excluding restructuring and other costs is calculated as net debt at the end of the period, divided by 12-month trailing EBITDA – excluding restructuring and other costs. Historically, this measure is substantially similar to the leverage ratio covenant in our credit facilities. Net debt and EBITDA – excluding restructuring and other costs are measures that do not have any standardized meanings prescribed by IFRS Accounting Standards and are therefore unlikely to be comparable to similar measures presented by other issuers. The calculation of these measures is set out in the following table. Net debt is one component of a ratio used to determine compliance with certain debt covenants.

* EBITDA is not a standardized financial measure under IFRS Accounting Standards and might not be comparable to similar measures disclosed by other issuers; we define EBITDA as operating revenues and other income less goods and services purchased and employee benefits expense. We report EBITDA because it is a key measure that management uses to evaluate the performance of our business, and it is also utilized to determine compliance with certain debt covenants.

12 | September 30, 2025

Net debt to EBITDA – excluding restructuring and other costs was 3.5 times as at September 30, 2025, compared to 3.8 times one year earlier. The decrease was largely due to the effect of the decrease in net debt levels, primarily due to the junior subordinated notes equity credit and the equity issued by our Terrion subsidiary to a non-controlling interest (see Note 28(b)), partially offset by spectrum acquisitions and business acquisitions; net debt levels were already elevated in the current and comparative periods due to our spectrum acquisitions and business acquisitions.

The earnings coverage ratio for the twelve-month period ended September 30, 2025, was 2.1 times, up from 1.9 times one year earlier. An increase in income before borrowing costs and income taxes raised the ratio by 0.4 and an increase in borrowing costs lowered the ratio by 0.2. The EBITDA – excluding restructuring and other costs interest coverage ratio for the twelve-month period ended September 30, 2025, was 5.2 times, down from 5.4 times one year earlier. An increase of $48 million in net interest costs decreased the ratio by 0.2.

TELUS Corporation Common Share dividend payout ratio

So as to be consistent with the way we manage our business, our TELUS Corporation Common Share dividend payout ratio is presented as a historical measure calculated as the sum of the dividends declared in the most recent four quarters for TELUS Corporation Common Shares, as recorded in the financial statements, net of dividend reinvestment plan effects (see Note 13), divided by the sum of free cash flow* amounts for the most recent four quarters for interim reporting periods (divided by annual free cash flow if the reported amount is in respect of a fiscal year). The historical measure for the twelve-month period ended September 30, 2025, is presented for illustrative purposes in evaluating our objective range.

*Free cash flow is not a standardized financial measure under IFRS Accounting Standards and might not be comparable to similar measures presented by other issuers; we define free cash flow as EBITDA (operating revenues and other income less goods and services purchased and employee benefits expense) excluding items that we consider to be of limited predictive value, including certain working capital changes (such as trade receivables and trade payables), proceeds from divested assets, and other sources and uses of cash, as found in the consolidated statements of cash flows. We have issued guidance on, and report, free cash flow because it is a key performance measure that management and investors use to evaluate the performance of our business.

September 30, 2025 | 13

Our calculation of TELUS Corporation Common Share dividends declared, net of dividend reinvestment plan effects, is as follows:

Our calculation of free cash flow, and its reconciliation to cash provided by operating activities, is as follows:

14 | September 30, 2025

Excluding credit risk, if any, arising from currency swaps settled on a gross basis, the best representation of our maximum exposure (excluding income tax effects) to credit risk, which is a worst-case scenario and does not reflect results we expect, is set out in the following table.

Cash and temporary investments, net

Credit risk associated with cash and temporary investments is managed by ensuring that these financial assets are placed with: governments; major financial institutions that have been accorded strong investment grade ratings by a primary rating agency; and/or other creditworthy counterparties. An ongoing review evaluates changes in the status of counterparties.

Accounts receivable

Credit risk associated with accounts receivable is inherently managed through the size and diversity of our large customer base, which encompasses substantially all consumer and business sectors in Canada. A program of credit evaluations of customers is followed and the amount of credit extended is limited when we deem it to be necessary. Accounts are considered to be past due (in default) when customers have failed to make the contractually required payments when due, which is generally within 30 days of the billing date. Any late payment charges are levied at an industry-based market rate or a negotiated rate on outstanding non-current customer account balances.

We maintain allowances for lifetime expected credit losses related to doubtful accounts. Factors considered when determining allowances for past-due accounts include: current economic conditions (including forward-looking macroeconomic data); historical information (including credit agency reports, if available); reasons for the accounts being past due; and the line of business from which the customer accounts receivable originated. These factors are also 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 balances above a specific threshold and on a statistically derived allowance basis for the remainder. No customer accounts receivable are written off directly to the doubtful accounts expense; the doubtful accounts expense is included in the Consolidated statements of income and other comprehensive income as Goods and services purchased.

September 30, 2025 | 15

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

Contract assets

Credit risk associated with contract assets is inherently managed through the size and diversity of our large customer base, which encompasses substantially all consumer and business sectors in Canada. A program of credit evaluations of customers is followed and the amount of credit extended is limited when we deem it to be necessary.

We maintain allowances for lifetime expected credit losses related to contract assets. Factors considered when determining allowances include: current economic conditions; historical information (including credit agency reports, if available); and the line of business from which the contract assets originated. These same factors are considered when determining whether to write off amounts charged to the impairment allowance for contract assets against contract assets.

Derivative assets (and derivative liabilities)

Counterparties to our material foreign exchange derivatives are major financial institutions that have been accorded investment grade ratings by a primary credit rating agency. Credit exposure to any single financial institution is limited and counterparties’ credit ratings are monitored. We do not give or receive collateral on swap agreements and hedging items due to our credit rating and those of our counterparties. While we are exposed to the risk of credit losses due to the potential non-performance of our counterparties, we consider this risk remote. Our derivative liabilities do not have credit risk-related contingent features.

As a component of our capital structure financial policies, discussed further in Note 3, we manage liquidity risk by:

Our debt maturities in future years are disclosed in Note 26(j). As at September 30, 2025, unchanged from December 31, 2024, TELUS Corporation could offer an unlimited amount of securities in Canada, and US$3.5 billion of securities in the United States, qualified pursuant to a Canadian shelf prospectus effective until September 2026, unchanged from December 31, 2024. We believe our investment grade credit ratings contribute to reasonable access to capital markets.

16 | September 30, 2025

We closely match the contractual maturities of our derivative financial liabilities with those of the risk exposures they are being used to manage.

The expected maturities of our undiscounted financial liabilities do not differ significantly from the contractual maturities, other than as noted in the accompanying tables. The contractual maturities of our undiscounted financial liabilities, including interest thereon (where applicable), are set out in the accompanying tables.

Net income and other comprehensive income for the nine- month periods ended September 30, 2025 and 2024, could have varied if the Canadian dollar: U.S. dollar exchange rate, the U.S. dollar: European euro exchange rate, market interest rates and virtual power purchase agreement forward element valuation varied by reasonably possible amounts from their actual statement of financial position date amounts.

Our sensitivity analysis for currency risk exposure has been determined based upon a hypothetical change taking place at the relevant statement of financial position date. We used the U.S. dollar-denominated and European euro-denominated balances and the notional amounts of our derivative financial instruments as at the relevant statement of financial position dates in these calculations.

September 30, 2025 | 17

The sensitivity analysis of our exposure to interest rate risk has been determined based upon a hypothetical change taking place at the beginning of the relevant fiscal year and being held constant through to the statement of financial position date. We used the principal and notional amounts as at the relevant statement of financial position dates in these calculations.

The sensitivity analysis of our exposure to wind discount risk and solar premium risk is based upon a hypothetical change taking place at the relevant statement of financial position date. The notional amounts of the virtual power purchase agreements as at the relevant statement of financial position dates have been used in these calculations.

In the sensitivity analysis, we reflected income tax expense on a net basis, calculated using the applicable statutory income tax rates for the reporting periods.
