Third Quarter of 2024 Highlights

Ternium achieved a strong level of shipments in the third quarter of 2024, on record-high sales volumes in Mexico, higher shipments in Brazil and a continued recovery in the Southern Region.

However, Adjusted EBITDA was $368 million in the third quarter of 2024, reflecting a relatively low margin. Steel revenue per ton decreased sequentially in the third quarter due to lower steel prices in Ternium’s main steel markets and a decrease in industrial contract prices in Mexico. This was partially offset by a modest decrease in steel cost per ton, as the company consumed previously purchased high-priced inventory during the third quarter.

Capital expenditures in the third quarter of 2024 amounted to $446 million, as Ternium progressed with its expansion programs in Mexico and with its new wind farm in Argentina. Cash provided by operating activities was $303 million after a working capital increase of $155 million. Consequently, Ternium’s net cash position decreased to $1.7 billion as of the end of September 2024 from net cash position of $1.9 billion as of the end of June.

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 payment date of the interim dividend will be November 21, 2024, with an ex-dividend date on November 15, 2024 and record date on November 18, 2024.

ANNUAL DIVIDEND<br><br>$ PER ADS

n Interim

Outlook

Ternium expects a slight sequential increase in adjusted EBITDA for the fourth quarter of 2024 due to improved margins partially offset by a reduction in shipments. Apparent demand in Mexico and Brazil is anticipated to decline due to year-end seasonality in the fourth quarter. Conversely, apparent demand in Argentina is expected to remain relatively stable, albeit at levels below historical volumes.

The company anticipates a continued decrease in cost per ton, as a result of the gradual consumption of lower-priced slabs and raw material inventories. However, realized steel prices are projected to decline in the fourth quarter of 2024 compared to the third quarter of 2024, mainly due to the reset of quarterly price contracts with industrial customers in Mexico at reduced levels.

During the third quarter, the company's new push-pull pickling line in the Pesquería industrial center, as well as three of the five finishing lines in Ternium's downstream expansion project, have started operations and are currently ramping up. In addition, our new wind farm in Argentina is expected to begin operations by year-end, boosting our use of self-generated renewable energy and reducing reliance on external sources. This will represent a significant milestone in our commitment to renewable energy and decarbonization.

ADJUSTED EBITDA<br><br>$ MILLION

Steel Segment

The Steel Segment shipments increased 7% sequentially in the third quarter of 2024. However, net sales in period remained stable compared to the second quarter of 2024 due to lower realized steel prices. The sequential decrease in revenue per ton was due to lower steel prices in Ternium’s main steel markets and lower contract prices in Mexico.

On a year-over-year basis, the Steel Segment shipments remained stable. Nevertheless, net sales decreased year-over-year as a result of lower steel prices in Ternium’s main steel markets.

In Mexico, shipments achieved a new record-high in the third quarter of 2024. Sales volumes to the industrial sector increased sequentially, including higher shipments to automotive manufacturers and a recovery in the sales to the HVAC sector. Shipments to the commercial market improved sequentially, albeit from a relatively low base.

In Brazil, shipments to industrial customers and distributors increased sequentially in the third quarter of 2024. On the other hand, sales volumes to automotive manufacturers remained unchanged. Demand for steel products in the country was strong. However, imports of steel products continued increasing in the third quarter, mainly from China.

In the Southern Region, steel shipments continued to recover in the quarter, mainly reflecting better demand

in Argentina from the construction sector, the automotive industry, and agribusiness and transportation equipment manufacturers.

Note: For information on the Steel Segment’s Cash Operating Income per Ton and Margin, see Exhibit I - Alternative performance measures - “Cash Operating Income - Steel Segment”.

The Steel Segment’s Cash Operating Income per Ton and Margin decreased sequentially in the third quarter of 2024 due to lower revenue per ton partially offset by slightly lower cost per ton.

Ternium’s and Usiminas’ blast furnace operations recorded efficiency gains in the period, particularly in fuel consumption. In addition, labor and maintenance costs decreased sequentially in the third quarter.

On the other hand, the company consumed high-cost inventory in the period. The decrease in raw material and slab market prices during 2024 was not totally reflected on Ternium’s cost of sales in the third quarter, as the company consumed inventories produced in prior periods.

Mining Segment

The Mining Segment shipments increased 13% sequentially in the third quarter of 2024, supported by higher production levels in our Mexican and Brazilian mining operations. However, net sales decreased slightly in the period reflecting lower iron ore market prices.

On a year-over-year basis, iron ore shipments decreased in the third quarter of 2024 reflecting lower production levels in our Mexican and Brazilian

operations. Net sales decreased slightly year-over-year in the third quarter, as lower sales volumes were partially offset by higher realized iron ore prices. The increase in revenue per ton was the result of an improved sales mix of iron ore products, partially offset by lower iron ore market prices.

Net Financial Results

Net financial results were a gain of $74 million in the third quarter of 2024. Of note in the period was a $57 million net foreign exchange gain, mainly reflecting the positive impact of the depreciation of the Mexican Peso and the appreciation of the Brazilian Real vis-a-

vis the US dollar on Ternium Mexico’s net short local currency position and Usiminas’ US dollar denominated debt, respectively. Usiminas uses the Brazilian Real as functional currency.

Income Tax Results

Ternium Mexico, Ternium Argentina and Ternium Brasil use the US 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 US dollar, as well as for the

effect of local inflation. Effective tax rates in the

second quarter and first nine months of 2024 included, in addition, the effect of a provision for ongoing litigation related to the acquisition of a participation in Usiminas and, in the third quarter and first nine months of 2023, certain non-cash effects related to the increase in the participation in Usiminas.

Net Income

Net Income was $93 million in the third quarter of 2024, on operating income of $175 million. Of note in the period were financial result gains of $74 million and deferred tax losses of $80 million.

Equity Holder’s Net Income was $32 million in the third quarter, or $0.16 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

Cash from operations reached $303 million in the third quarter of 2024, including a $155 million increase in working capital. The change in working capital was due to a $258 million decrease in trade payables and other liabilities, partially offset by a $54 million decrease in inventories and a $49 million net decrease in trade and other receivables.

Capital expenditures amounted to $446 million in the third quarter of 2024. Among other initiatives, Ternium made progress in the construction of new facilities in its Pesquería industrial center and in the construction of a new wind farm in Argentina.
