Second Quarter of 2025 Highlights

Ternium’s Adjusted EBITDA Margin rose sequentially to 10% in the second quarter, primarily driven by higher realized steel prices, mainly in Mexico. Sales volumes of steel products declined slightly sequentially, largely due to lower shipments in Mexico and the US, partially offset by higher shipments in Argentina. The uncertain business climate in Mexico related to trade discussions weighed on local steel demand in the period. Sales volumes in the country were also affected by an increase of the US import tariff on steel and derivative products under Section 232 to 50%.

Cash from operations in the second quarter totaled $1.0 billion driven by a significant decrease in working capital, consistent with declining sales volumes. Capital expenditures amounted to $810 million in the period, mainly in connection with the ongoing expansion at the company’s industrial center in Pesquería, Mexico. In addition, the company paid a dividend of $353 million corresponding to the balance of the total dividend declared for the year 2024. Ternium’s net cash position as of the end of June 2025 was $1.0 billion, decreasing by $268 million since the end of March 2025.

Outlook

Ternium expects Adjusted EBITDA to keep improving in the third quarter of 2025, supported by ongoing cost reduction initiatives and operational enhancements. The company is concentrating on a comprehensive plan for cost management, aiming to improve profitability and resilience even as challenging market conditions persist.

In Mexico, the steel sector is dealing with uncertainty from ongoing tariff talks with the U.S. In response to shifting market conditions, the Mexican government has begun implementing trade measures intended to defend local producers against unfair trade practices, leading to early declines in steel imports, especially from Asia. Consequently, Ternium expects some increase in shipments in Mexico in the third quarter of 2025 compared to the second quarter of the year.

Unlike the recent developments in Mexico, Brazil’s steel market continues to struggle with a high level of unfairly traded steel imports, especially from China, which is hurting local producers. In this context, Usiminas keeps working on strengthening its competitiveness and expects to achieve an improved cost per ton in the third quarter of 2025 compared to the second quarter of the year.

In Argentina, Ternium anticipates that shipments in the third quarter of 2025 will remain relatively stable after a significant sequential increase during the second quarter driven by seasonal factors as well as a gradually recovering macroeconomic environment.

◦Depreciation and amortization;

◦Income tax results;

◦Net financial results;

◦Equity in earnings of non-consolidated companies; and

◦Provision charge for ongoing litigation related to the acquisition of a participation in Usiminas.

And adjusted to include the proportional EBITDA in Unigal (70% participation).

Adjusted EBITDA Margin equals Adjusted EBITDA divided by net sales. For more information see Exhibit I - Alternative performance measures - “Adjusted EBITDA”.


ADJUSTED EBITDA $ MILLION

Steel Segment

In the second quarter of 2025, the Steel Segment’s net sales remained relatively stable sequentially. Higher realized steel prices were largely offset by reduced sales volumes, reflecting lower shipments in Mexico, Brazil and Other Markets, while shipments increased in the Southern Region.

Year-over-year, the Steel Segment’s net sales declined by 13% in the second quarter of 2025. Steel revenue per ton fell across all regions due to lower steel prices. Sales volumes decreased as well, reflecting lower shipments in Mexico and Other Markets that were partially offset by higher shipments in the Southern Region.


SHIPMENTS - STEEL PRODUCTS MILLION TONS

NET SALES - STEEL SEGMENT $ BILLION


n Usiminas

Ternium’s sales volume in Mexico declined sequentially in the second quarter due to reduced shipments to industrial customers and a softer commercial market. On a year-over-year basis, the contraction in second-quarter of 2025 volumes was largely driven by the commercial market weakness.

In Brazil, shipments in the second quarter of 2025 remained broadly in line with those of the same period in the prior year, while showing a modest sequential decline. Although domestic steel demand maintained its upward trajectory, the expansion was accompanied by an extraordinary surge in flat steel product imports.

In the Southern Region, shipments rose both sequentially and year-over-year during the second quarter of 2025, reflecting a recovery in steel demand in Argentina and, on a sequential basis, a seasonal rebound in activity.

In Other Markets, shipments fell by 14% in the second quarter of 2025, both sequentially and year-over-year, primarily driven by lower sales in the US.

CASH OPERATING INCOME - STEEL SEGMENT $ MILLION

Year-over-year, the Steel Segment’s Cash Operating Income declined in the second quarter of 2025, reflecting reduced margins and sales volumes. The contraction in margins was primarily attributable to lower realized steel prices, partially offset by decreased raw material and purchased slab costs.

Mining Segment

The Mining Segment’s net sales remained relatively stable sequentially in the second quarter of 2025, as higher sales volumes were largely offset by a decrease in realized iron ore prices. Shipment levels in the second quarter were supported mainly by increased

iron ore production. Year-over-year, the Mining Segment’s net sales rose by 3% in the second quarter of 2025 reflecting higher sales volumes, partially offset by lower realized iron ore prices.

In the second quarter of 2025, the Mining Segment’s Cash Operating Income decreased sequentially and on a year-over-year basis as a result of lower margins, partially offset by higher sales volumes.

The decrease in margins was primarily driven by reduced iron ore realized prices, partially mitigated by lower operating costs per ton.

Net Financial Results

Net financial results for the second quarter of 2025 recorded a $30 million loss. The net foreign exchange result for the period was a $35 million loss, driven mainly by the impact of the Mexican Peso’s appreciation against the U.S. dollar on Ternium

Mexico’s net short local currency position and the impact of the Argentine Peso’s depreciation against

the U.S. dollar on Ternium Argentina’s net long local

currency position.

These results account for the impact of local currency fluctuations against the U.S. dollar, as well as for the effect of local inflation.

Net Income

In the second quarter of 2025, Ternium recorded net income of $259 million, which included a provision

adjustment charge of $40 million for ongoing litigation related to the acquisition of a participation in Usiminas. This adjustment accounted for interest accrual and the appreciation of the Brazilian Real versus the US dollar in the quarter. Excluding this, Adjusted Net Income amounted to $299 million, on operating income of $199 million and an income tax gain of $104 million.

Adjusted Equity Holder’s Net Income was $251 million in the second quarter, or $1.28 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 second quarter of 2025, cash from operations amounted to $1.0 billion after a $787 million decrease in working capital. During the period, inventories declined by $429 million, trade and other receivables decreased by $198 million, and trade payables and other liabilities increased by $161 million.

The reduction in the inventory value was driven by decreased stock volumes and costs. Capital expenditures totaled $810 million in the second quarter, primarily reflecting the progress made in the construction of the new facilities at Ternium’s industrial center in Pesquería, Mexico.
