INDEPENDENT PROXY ADVISORY FIRMS ISS AND GLASS LEWIS RECOMMEND TECK SHAREHOLDERS VOTE "FOR" THE MERGER OF EQUALS WITH ANGLO AMERICAN

Independent proxy advisory firms Institutional Shareholder Services Inc. and Glass Lewis & Co. have recommended that Teck shareholders vote for the company's merger of equals with Anglo American PLC. As previously announced, Teck has scheduled a special meeting of shareholders on Dec. 9, 2025.

In their reports dated Nov. 26, 2025, and Nov. 21, 2025, respectively, ISS and Glass Lewis stated:

• ISS: "The arrangement makes strategic sense in light of the anticipated synergies, strategic benefits and opportunity for additional upside through ownership in the combined company. The universe of potential buyers is limited, the board actively explored alternative transaction structures in order to maximize shareholder value, shareholders are expected to benefit from increased liquidity and stronger financial position for the combined company, and the market reaction has been positive."
• Glass Lewis: "Over all, the strategic merits of the combination appear well supported by the scale, asset quality and long-term copper growth profile of the combined company. If successfully executed, the merger positions Anglo Teck as a financially stronger and more resilient producer with meaningful upside from operational integration and future development opportunities. ... On balance, we believe the transaction presents a compelling strategic opportunity for Teck shareholders."

"The Teck board has determined that a merger of equals with Anglo American is the best path forward for Teck shareholders and all stakeholders," said Jonathan Price, president and chief executive officer. "The recent recommendations from ISS and Glass Lewis further affirm this view. This merger is a unique opportunity to build a new global critical minerals champion headquartered in Canada with increased scale, a world-class portfolio of copper and critical minerals assets, and enormous growth potential. We are confident the transaction will drive significant value creation and encourage all Teck shareholders to vote for the merger."

Teck shareholders encouraged to vote ahead of the proxy deadline

Teck shareholders of record as of the close of business on Oct. 20, 2025, should vote for the merger now and can advance vote up to the proxy voting deadline of 11 a.m. PST on Dec. 5, 2025.

Teck's notice of meeting, management information circular and other related meeting materials have been mailed to shareholders and can also be accessed on-line on Teck's website and under Teck's issuer profiles on SEDAR+ and EDGAR.

Any shareholder who has questions about how to vote should contact the proxy solicitation agents.
