Note: Each American Depositary Share, or ADS, represents 10 shares of Ternium’s common stock. Results are based on a weighted average number of shares of common stock outstanding (net of treasury shares) of 1,963,076,776.

Third Quarter of 2025 Highlights

In the third quarter of 2025, Ternium continued improving its Adjusted EBITDA Margin, as steel production costs decreased, mainly reflecting lower raw material and purchased slab costs, as well as efficiency gains.

Net result in the third quarter of 2025 was a loss of $270 million. This result includes a $405 million income tax charge in connection with a write-down of deferred tax assets at Usiminas and a $32 million loss stemming from the quarterly update of the value of a provision for ongoing litigation related to the acquisition of a participation in Usiminas.

As of the end of September 2025, Ternium’s Net Cash position stood at $715 million, decreasing by $303 million since June 2025. This decline reflects the cash demands associated with the ongoing expansion of the company’s industrial center in Pesquería, Mexico, and changes in the fair value of Argentine securities.

Interim Dividend Payment

Ternium’s board of directors approved the payment of an interim dividend of $0.90 per ADS ($0.09 per share), or $177 million based on total shares of common stock outstanding, net of treasury shares.

The interim dividend payment date will be November 11, 2025, with record date on November 10, 2025.

Considering the dividend paid in May 2025 and the announced interim dividend for November 2025, total distributions during 2025 will amount to $2.70 per ADS. Considering Ternium’s ADS prevailing market prices, this is equivalent to a dividend yield of approximately 7%.

Outlook

Ternium anticipates a slight decrease in Adjusted EBITDA for the fourth quarter of 2025 compared to the third quarter, largely due to the typical seasonal reduction in shipments in all of the company’s markets. Ternium expects its Adjusted EBITDA Margin to remain in line with the third quarter, as a projected decline in revenue per ton in Mexico and Argentina should be largely balanced by ongoing reductions in cost per ton. This reflects lower raw material costs, as well as Ternium’s ongoing commitment to implementing cost optimization strategies throughout its operations.

In Mexico, the company expects shipments to decline sequentially in the fourth quarter of 2025, reflecting both subdued construction activity and end-of-year seasonality. The Mexican steel market continues to face challenges, particularly from ongoing tariff negotiations with the United States, which have contributed to an environment of uncertainty.

In Brazil, while the steel market continues to face significant challenges from a persistent influx of unfairly traded steel imports, particularly from Asian producers, Usiminas is proactively strengthening its competitiveness through ongoing cost reduction initiatives and operational improvements, leading to expectations of achieving a better cost per ton in the fourth quarter of 2025 compared to the previous quarter.

In Argentina, with the uncertainty related to the mid-term elections now behind us, the most dynamic sectors of the economy, such as agriculture, mining, and oil and gas, offer significant opportunities for the company’s value chain.

Steel Segment

In the third quarter of 2025, the Steel Segment’s net sales remained stable sequentially with slightly higher sales volumes offset by slightly lower realized steel prices. Year-over-year, the Steel Segment’s net sales declined by 13% in the third quarter of 2025. Sales volumes decreased by 9% year-over-year, primarily

driven by lower shipments in Mexico and Brazil, partially offset by higher shipments in the Southern Region. Steel revenue per ton declined by 5% year-over-year, reflecting lower realized steel prices particularly in the Southern Region and Other Markets.

n Usiminas

Ternium’s shipments in Mexico posted a moderate sequential increase in the third quarter of 2025. On a year-over-year basis, sales volumes in the third quarter declined, as ongoing uncertainty surrounding trade negotiations with the U.S. and weak infrastructure investments in the country continued to dampen overall steel demand.

In Brazil, shipments in the third quarter of 2025 showed a modest sequential increase. On a year-over-year basis, sales volumes declined. Although steel demand in the country grew during 2025, this was offset by a sharp increase in flat steel product imports.

In the Southern Region, shipments showed a slight sequential decrease in the third quarter of 2025. Year-over-year, sales volumes increased, reflecting better steel demand in Argentina.

In Other Markets, declining shipments in the US were partially offset by higher sales volumes in other destinations both sequentially and year-over-year.

Steel Cash Operating Income

The Steel Segment’s Cash Operating Income increased by $41 million sequentially in the third quarter of 2025, mainly driven by better margins. The margin improvement reflected the company's efforts to increase the efficiency in its operations and a decrease in raw material, purchased slab and energy costs, partially offset by a slight decrease in realized steel prices.

Year-over-year, the Steel Segment’s Cash Operating Income increased by $82 million in the period, driven by better margins partially offset by lower sales volumes. The margin improvement mainly reflected a decrease in raw material and purchased slab costs, partially offset by lower realized steel prices.

Mining Segment

The Mining Segment’s net sales decreased by 5% sequentially in the third quarter of 2025, reflecting lower sales volumes and a slight decrease in realized iron ore prices. Year-over-year, the Mining Segment’s

net sales increased slightly in the third quarter of 2025, as an increase in sales volumes was mostly offset by lower realized iron ore prices.

Mining Cash Operating Income

The Mining Segment’s cash operating income decreased sequentially and year-over-year in the third quarter of 2025. The sequential decrease was primarily driven by lower margins and reduced sales volumes. On a year-over-year basis, the decline

reflected lower margins, partially offset by increased sales volumes. The margin compression in the third quarter of 2025, as compared to the prior quarter and to the same period in 2024, was the result of higher unit costs and lower realized iron ore prices.

Net Financial Results

Net financial results for the third quarter of 2025 were a loss of $35 million. This included a loss of $34 million in net foreign exchange results, driven mainly by the impact of the Argentine Peso’s depreciation

against the U.S. dollar on Ternium Argentina’s net long local currency position and the impact of the Mexican Peso’s appreciation against the U.S. dollar on Ternium Mexico’s net short local currency position.

Income Tax Results

Ternium Mexico, Ternium Argentina and Ternium Brasil use the U.S. dollar as their functional currency and are, therefore, affected by deferred tax results. These results account for the impact of local currency fluctuations against the U.S. dollar, as well as for the effect of local inflation.

In the third quarter of 2025, Ternium’s income tax expense totaled $444 million. This included a $405 million charge in connection with the write-down of deferred tax assets at Usiminas, following the performance of a recoverability assessment of such assets.

This result includes a loss of $405 million in connection with the write-down of deferred tax assets at Usiminas, and a loss of $32 million on account of interest accruals and the appreciation of the Brazilian Real in connection with the provision for ongoing litigation concerning the acquisition of a participation in Usiminas.

Equity Holder’s Net Income was $21 million in the period, or $0.10 per ADS, mainly after accounting for the participation of a 76.7% non-controlling interest in Usiminas and a 37.4% non-controlling interest in Ternium Argentina.

Cash Flow and Liquidity

In the third quarter of 2025, cash from operations amounted to $535 million. Working capital decreased by $174 million as a result of a $125 million decline in inventories and a $76 million increase in trade payables and other liabilities, partially offset by a $27 million increase in trade and other receivables.

The inventory value reduction was mainly driven by lower unit costs. Capital expenditures totaled $711 million in the third quarter, primarily reflecting the progress made in the construction of the new facilities at Ternium’s industrial center in Pesquería, Mexico.
