Exhibit 99.1

TELUS Digital Files Management Information Circular and Announces Receipt of Interim Order In Respect of Arrangement with TELUS Corporation

TELUS Digital’s independent Special Committee unanimously recommends that shareholders vote IN FAVOUR of the Arrangement

Arrangement provides a 52.0% premium over the unaffected price, with multiple consideration options available to shareholders

VANCOUVER, British Columbia – September 18, 2025 – TELUS International (Cda) Inc. (“TELUS Digital”) (NYSE & TSX: TIXT) today announced that it has filed its management information circular (the “Circular”) and accompanying materials in connection with the special meeting of shareholders (the “Special Meeting”) to be held virtually at 9:00 a.m. (Vancouver time) on October 27, 2025 to consider the proposed arrangement with TELUS Corporation (“TELUS”) (TSX: T, NYSE: TU) (the “Arrangement”). TELUS Digital also announced that on September 17, 2025, the Supreme Court of British Columbia granted an interim order in respect of the Arrangement, authorizing the calling and holding of the Special Meeting and setting out certain procedures to follow in respect of the Special Meeting.

The Circular provides shareholders with comprehensive information regarding the Arrangement under which TELUS will acquire all outstanding multiple voting shares and subordinate voting shares of TELUS Digital not already owned by TELUS for US$4.50 per share, reflecting aggregate consideration of US$539 million.

Immediate and Long-Term Value for Shareholders

TELUS Digital’s Special Committee of independent directors (the “Special Committee”), having consulted with management and the Special Committee’s legal and financial advisors in evaluating the Arrangement, believes the Arrangement provides more immediate value to minority shareholders on a risk-adjusted basis than is expected to be realizable by TELUS Digital as a stand-alone entity in the foreseeable future. The Arrangement is expected to enable enhanced AI and SaaS transformation capabilities across TELUS’ telecommunications, health, and agriculture and consumer goods businesses, while accelerating TELUS Digital’s global growth in key verticals including financial technology, gaming and technology, communications and media, and health.

Highlights:

●

Unanimous board recommendation (with interested directors abstaining) following a rigorous independent Special Committee review process

●

US$4.50 per share represents a 52.0% premium over the unaffected closing price of US$2.96 per subordinate voting share on the New York Stock Exchange (the “NYSE”) on June 11, 2025, and a 62.6% premium over the 30-day volume-weighted unaffected average price of TELUS Digital subordinate voting shares on the NYSE prior to June 12, 2025

	●	Transaction valued at US$539 million in aggregate consideration
	●	Multiple consideration options for TELUS Digital shareholders provide flexibility and allow future participation in TELUS growth, subject to proration described below

Pursuant to the Arrangement Agreement, shareholders can elect to receive one of three consideration options for each TELUS Digital share: (i) US$4.50 in cash, (ii) 0.273 of a TELUS common share, or (iii) a combination of US$2.25 in cash and 0.136 of a TELUS common share. Shareholders electing options (ii) or (iii) will be subject to proration such that the aggregate consideration will include no more than 25% in TELUS common shares.

Independent Process Confirms Fair Value

Following an extensive independent review process, the Special Committee unanimously determined that the Arrangement is in the best interests of TELUS Digital and fair to minority shareholders. The Special Committee unanimously recommended the Arrangement to the Board of Directors. The TELUS Digital Board of Directors unanimously recommend (with interested directors abstaining) that shareholders vote IN FAVOUR of the Arrangement. This determination was supported by, among other considerations, a rigorous negotiation process that resulted in an increase to TELUS’ original offer from US$3.40 to US$4.50 per subordinate voting share. The reasons for the TELUS Digital Board’s unanimous recommendation are more fully described under the headings “Recommendation of the Board and the Special Committee” and “Special Factors – Reasons for the Arrangement” in the Circular.

Strong Shareholder Support Secured

The transaction is supported by Riel B.V. (indirectly and wholly-owned by BPEA Private Equity Fund VI, L.P.1., BPEA Private Equity Fund VI, L.P.2 and certain of its affiliates) (“EQT”), TELUS Digital’s largest minority shareholder. As of September 12, 2025, the record date for the Special Meeting, following EQT’s conversion of its multiple voting shares, EQT holds approximately 37.7% of the outstanding subordinate voting shares of TELUS Digital. All of TELUS Digital’s directors and officers, holding or having control or direction over approximately 2.9% of the outstanding subordinate voting shares (following the conversion by EQT of its multiple voting shares), have also agreed to support the transaction.

If approved by shareholders, the transaction is expected to close at the end of October 2025, subject to final court approval and other customary conditions for a transaction of this type. The parties have determined that no FDI regulatory approvals are required in connection with the Arrangement and have therefore waived the related closing condition.
