SEPTEMBER 30, 2026

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, which were wholly owned as at September 30, 2026, are TELUS Communications Inc. and TELUS Health Inc.

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, 2025.

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, 2025. 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, 2026, were authorized by our Board of Directors for issue on November 6, 2026.

Inventories primarily consist of mobile handsets, parts and accessories, which totalled $344 million as at September 30, 2026 (December 31, 2025 – $376 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, 2026, totalled $0.5 billion (2025 – $0.6 billion) and $1.6 billion (2025 – $1.7 billion), respectively.

Although much of the substance of IAS 1, Presentation of Financial Statements, will carry over into the new standard:

September 30, 2026 | 7

The new standard is effective for annual reporting periods beginning on or after January 1, 2027, with earlier adoption permitted. We are continuing to assess the impacts of the new standard and, other than as set out above, do not expect the totality of our financial disclosure to be materially affected by the application of the new standard.

Statement of income and other comprehensive income presentation

Of most significance, relative to our historical practice, IFRS 18, Presentation and Disclosure in Financial Statements, will newly define what income and expenses are to be classified in the operating and financing categories of, and will newly introduce an investing category to, our statement of income and other comprehensive income.

The income and expenses arising from investments in associates and joint ventures accounted for applying the equity method will be classified in the newly introduced investing category of the statement of income and other comprehensive income. Relative to our historical practice (see Note 7), the possible effect of applying the new standard for primary financial statement purposes will be reclassifying equal and offsetting amounts between operating income* and investing income; such possible effect is not currently expected to be material.

Irrespective of an entity’s capital structure financial policies’ approach to cash management, the new standard prescribes that an entity such as ourselves classify any income generated from cash and cash equivalents as investing income. We manage our financing expense on a net basis by offsetting income on cash and cash equivalents against such expense and thus, historically, have not separately recognized such income as a revenue. Relative to our historical practice (see Note 9), the possible effect of applying the new standard for primary financial statement purposes will be to increase the investing income and financing expense* by equal and offsetting amounts; such possible effect is not currently expected to be material.

The new standard requires that the income and expenses from other assets, such as investment properties (as defined by IFRS Accounting Standards), which do not comprise a specified main business activity and which generate a return individually and largely independently of our other resources, be classified in the newly introduced investing category of our statement of income and other comprehensive income. Relative to our historical practice, the possible effect of applying the new standard for primary financial statement purposes will be reclassifying equal and offsetting amounts between operating income^* and investing income; such possible effect is not currently expected to be material.

Foreign exchange differences arise due to fluctuations in foreign exchange rates between the time of a foreign currency-denominated transaction and its settlement. We manage such differences as a part of our financing management. As such, we establish hedging relationships and apply hedge accounting for a significant portion of our U.S. dollar-denominated transactions. However, it is not practicable to establish hedging relationships and apply hedge accounting for all foreign currency-denominated transactions. In our instance, primarily in respect of unhedged foreign exchange exposures (or not accounted for as a foreign currency translation adjustments arising from translating financial statements of foreign operations), the new standard prescribes that the default classification for foreign exchange differences is to be operating activities, irrespective of an entity’s financing management. Relative to our historical practice (see Note 9), the possible effect of applying the new standard for primary financial statement purposes will be reclassifying any such equal and offsetting default foreign exchange differences between Goods and services purchased within operating activities* and financing expense*; such possible effect is not currently expected to be material.

Management-defined performance measures

IFRS 18, Presentation and Disclosure in Financial Statements will require financial statement disclosure of management-defined performance measures (which the new standard restricts to subtotals of income and expense and, among other requirements, which are used in public communications outside of the financial statements) and their reconciliation to the most directly comparable listed or required IFRS Accounting Standard totals or subtotals. Management-defined performance measures present management’s view of only limited aspects of management-defined financial performance as a whole^*** and are not necessarily comparable with measures sharing similar labels or descriptions provided by other entities.

Judgment is required in identifying which of our measures may be management-defined performance measures. Due consideration must be given to the view that differing opinions may reasonably exist regarding what constitutes a performance measure and/or a management-defined performance measure, particularly so when a measure is multi-faceted and serves multiple purposes. On a continuing basis, as we continue to develop and evolve our business, we review and evolve our measures, including total of reportable segments measures and capital management measures, to identify those which may have become possible management-defined performance measures, and we review our possible management-defined performance measures to assess whether they may have ceased to be such.

Our management-defined performance measures possibly include, among others, adjusted net income attributable to Common Shares (the numerator of adjusted net income per basic share). Adjusted net income excludes the effects of (if, and as, applicable):

Adjusted net income attributable to Common Shares is a measure used to evaluate performance at a consolidated level and excludes items that, in management’s view, may obscure underlying trends in business performance or are atypical items that do not reflect our ongoing operations. It should not be considered an alternative to Net income (loss) in measuring our performance.

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:

10 | September 30, 2026

During 2026, our financial objectives, which are reviewed annually, were unchanged from 2025. 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 disclosed 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 (upon application of IFRS 18, Presentation and Disclosure in Financial Statements (see Note 2(b)), EBITDA possibly may not be a management-defined performance measure); 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.

September 30, 2026 | 11

Net debt to EBITDA – excluding restructuring and other costs was 3.6 times as at September 30, 2026, compared to 3.5 times one year earlier. In addition to a decrease in EBITDA – excluding restructuring and other costs, the increase in the ratio was also due to the effect of the increase in net debt levels arising from current and prior period acquisitions of spectrum and businesses, offset by the junior subordinated notes equity credit.

12 | September 30, 2026

The earnings coverage ratio for the twelve-month period ended September 30, 2026, was (0.3) times, down from 2.1 times one year earlier. A decrease in income before borrowing costs and income taxes lowered the ratio by 2.4 and an increase in borrowing costs immaterially lowered the ratio. The EBITDA – excluding restructuring and other costs interest coverage ratio for the twelve-month period ended September 30, 2026, was 4.8 times, down from 5.2 times one year earlier. An increase of $95 million in net interest costs lowered the ratio by 0.3.

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).

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

^* 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 presented in the consolidated statements of cash flows. We have issued guidance on, and report, free cash flow because it is a key financial performance measure that management and investors use to evaluate the financial performance of our business.

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 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 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; doubtful accounts expense is included in the Consolidated statements of income and other comprehensive income as a part of Goods and services purchased.

September 30, 2026 | 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 the amounts of these 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(i). As at September 30, 2026, unchanged from December 31, 2025, TELUS Corporation could offer an unlimited amount of securities in Canada, and $1.9 billion of securities in the United States, qualified pursuant to a Canadian shelf prospectus in effect until January 2029 (December 31, 2025 – January 2029). We believe our investment grade credit ratings contribute to reasonable access to capital markets.

16 | September 30, 2026

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.
