TX · Ternium S.A.

Ternium S.A.'s Board of Directors on April 15, 2026, revised its dividend recommendation for the year ended December 31, 2025, lowering the per-share amount from the initially proposed USD 0.27 to USD 0.22, equivalent to USD 2.20 per ADS, for a total payout of USD 432 million net of treasury shares. This adjustment incorporates the interim dividend of USD 0.09 per share already disbursed on November 12, 2025, from the share premium account, leaving a balance payment of USD 0.13 per share or USD 255 million scheduled for May 15, 2026, sourced from the financial year's profit. The company's 2025 annual accounts report a profit of USD 722 million, confirming sufficient distributable reserves including retained earnings exceed the proposed distribution. Post-dividend balance, the remaining profit will bolster retained earnings. Shareholder ratification at the annual general meeting is required, with the Board empowered to adjust payment terms if approved. This supplement solely amends Item 3 of the prior Shareholders Meeting Brochure and Proxy Statement, preserving all other proposals.
