Second Quarter of 2026 Highlights

Ternium delivered a robust performance in the second quarter of 2026. Adjusted EBITDA rose sequentially by 50% to $717 million, driven by higher sales volumes and better margins. In Mexico, steel market fundamentals continued to strengthen, amid the implementation of more effective measures against unfairly traded steel imports and the normalization of inventories across the value chain. Likewise, the measures adopted by the Brazilian government to promote fair competition contributed to a more constructive business sentiment across the domestic steel industry. Meanwhile, sales volumes in the Southern Region rebounded in line with seasonal demand trends. The company’s net income in the second quarter of 2026 reached $465 million.

Capital expenditures amounted to $431 million during the second quarter. The construction of Ternium’s new steel shop at its industrial center in Pesquería, Mexico, is progressing on schedule. In May 2026, the company paid a dividend to shareholders of $255 million, corresponding to the balance of the total dividend declared for the year 2025. Meanwhile, cash flow from operating activities amounted to $256 million after a $418 million increase in working capital, primarily in connection with higher sales and increased costs. The company recorded a Net Debt position of $112 million at the end of June 2026, compared to Net Cash position of $327 million at the end of March 2026.

Outlook

Ternium expects Adjusted EBITDA to increase in the third quarter of 2026 compared to the second quarter, driven by higher shipments and an improved Adjusted EBITDA margin. The margin expansion should reflect higher revenue per ton, partially offset by an increase in cost per ton.

In Mexico, the company expects shipments to continue recovering in the third quarter of 2026, as the commercial market keeps its momentum. New pipeline projects and the substitution of Asian imported steel at several OEMs are starting to generate additional volumes, while public infrastructure works should provide further support beyond the quarter.

In Brazil, steel demand remains uneven, with resilience in the automotive industry and in infrastructure equipment offset by weaker demand from agricultural machinery. High imports of steel and of manufactured goods with steel content continue to weigh on the market. Trade defense is nevertheless gaining ground, as the steel quota system was renewed until June 2027 and a final decision on the antidumping case on hot rolled coils from China is expected in the coming months.

In Argentina, energy, mining and agriculture are expected to remain strong, with construction recovering gradually from still low levels. Manufacturing activity remains weaker, held back by soft domestic demand and strong competition from imports.

Steel Segment Second Quarter of 2026 Results

The Steel Segment’s net sales increased both sequentially and year-over-year in the second quarter of 2026, driven by higher shipments and revenue per ton. Sequentially, shipment volumes increased in Mexico and the Southern Region, while realized steel prices rose mainly in Mexico and

Brazil. Compared to the same period of 2025, the growth in sales volumes was driven by the strength of the Mexican market, which more than offset a decrease in shipments across all other markets. Meanwhile, realized steel prices increased year-over-year in Mexico, Brazil and Other Markets.


SHIPMENTS - STEEL PRODUCTS MILLION TONS


NET SALES - STEEL SEGMENT $ BILLION

In Mexico, shipments to the commercial market continued to strengthen, posting significant year-over-year growth in the second quarter of 2026. Sales volumes to industrial customers were broadly stable sequentially, remaining below those in the same period of 2025.

In Brazil, sales volumes were largely unchanged sequentially, with Usiminas continuing to prioritize margin over volume. Flat steel imports declined in the second quarter, following the implementation of government measures aimed at curbing import surges and supporting more balanced competitive conditions.

In the Southern Region, steel shipments increased sequentially in the second quarter consistent with a seasonal rebound in activity, as underlying demand for steel products remained relatively stable.

In Other Markets, shipments in the second quarter of 2026 were broadly stable sequentially. On a year-over-year basis, sales volumes declined primarily due to decreased shipments in the US market.

The Steel Segment’s Cash Operating Income rose by $240 million sequentially in the second quarter of 2026, driven by higher realized steel prices and greater sales volumes, partially offset by slightly higher unit costs. Year-over-year, the Steel Segment’s Cash Operating Income increased by $300 million in

the quarter, on higher realized steel prices, increased sales volumes and lower unit costs. Cost per ton declined year-over-year mainly driven by lower raw material and purchased slab costs, aided by the company’s ongoing initiatives to improve efficiency.

Mining Segment Second Quarter of 2026 Results

Net sales in the Mining Segment increased both sequentially and year-over-year in the second quarter of 2026. Sequential growth was primarily driven by the Brazilian operations’ seasonal rebound, partially

offset by lower realized iron ore prices. Compared with the same period in 2025, the rise in net sales in the second quarter of 2026 was mainly the result of higher realized iron ore prices.

Net Financial Results

Net financial results were a loss of $39 million for the second quarter of 2026, primarily driven by a $34 million loss in foreign exchange results. This amount mainly reflected the negative effect of the appreciation of the Mexican Peso and the Brazilian Real against the

US Dollar on net short local currency positions at Ternium’s subsidiaries in these countries, and the negative effect of the depreciation of the Argentine Peso against the US Dollar on a net long local currency position at Ternium Argentina.

Income Tax Results

Ternium’s subsidiaries use the U.S. dollar as their functional currency; as a result, fluctuations between their local currencies and the U.S. dollar lead to the recognition of deferred tax results. In the second quarter of 2026, the company recorded a deferred tax

gain of $86 million mainly driven by the positive effect of the appreciation of the Mexican Peso against the US Dollar.

Net Income

In the second quarter of 2026, Ternium’s net income amounted to $465 million.

Equity Holder’s Net Income was $344 million in the period, or $1.75 per ADS, mainly after accounting for the participation of a 62.5% non-controlling interest in Usiminas and a 37.4% non-controlling interest in Ternium Argentina.
