Fourth Quarter and Full Year 2024 Highlights
The Mexican steel market experienced a downturn in the fourth quarter of 2024, due to year-end seasonality and a weakened commercial market. This weakness was partly influenced by uncertainties arising from the change in government administration in both Mexico and the United States, as well as heightened rhetoric from the U.S. on trade measures. Despite this, for the full year 2024 steel sales volumes in Mexico remained relatively stable, as the weakness in the commercial market was largely offset by continued growth of Ternium’s steel shipments to industrial customers.
The Brazilian steel market softened in the fourth quarter, largely due to year-end seasonality. For the full year 2024, Usiminas successfully capitalized on an increased local demand for steel products, despite facing substantial steel imports into Brazil, aided by an improved operating performance. With Ternium fully consolidating Usiminas’ results from July 2023 onwards, reported steel shipments for 2024 saw a significant increase compared to those of 2023.
In the Southern Region, steel sales volumes in the fourth quarter of 2024 reflected a seasonal demand decline in Argentina. For the full year 2024, the company experienced a 20% decrease in steel shipments in the Southern Region primarily in connection with the Argentine government’s economic stabilization measures, which had a significant impact in the first quarter followed by a gradual improvement throughout the year.
2

In Other Markets, steel shipments in the fourth quarter reflected a decrease in sales volumes in the US. For the full year 2024, steel sales volumes improved across the board following a relatively weak performance in the prior year.
Ternium’s realized steel prices continued to decline in the fourth quarter of 2024. The company’s steel cost per ton also fell, although it lagged behind the reduction in raw material and slab market prices as the company consumed previously purchased higher-priced inventories. For the full year 2024, realized steel prices decreased by $116 year-over-year. This decline was partially offset by a decrease in steel cost per ton.
Ternium’s net income totaled $333 million in the fourth quarter of 2024. The company recorded a $404 million provision reversal for ongoing litigation related to the acquisition of a participation in Usiminas in 2012. Excluding this provision reversal, Adjusted Net Loss was $71 million. For the full year 2024, Ternium’s net income totaled $174 million. During the year, the company recorded a net $410 million provision for the aforementioned litigation. Excluding this provision, Adjusted Net Income for 2024 was $584 million.
In 2024, dividends paid to the company’s shareholders amounted to $609 million. Capital expenditures for the year reached $1.9 billion, showcasing Ternium’s progress in expanding its industrial center in Pesquería, Mexico, and the construction of a new wind farm in Argentina, which was inaugurated by the end of the year. Despite these significant cash disbursements, the company’s net cash position at the end of 2024 was $1.6 billion. Strong operating cash flow of $1.9 billion and a $457 million increase in the fair value of financial instruments helped maintain this solid financial position.
Annual Dividend Proposal
Ternium’s board of directors proposed that an
annual dividend of $2.70 per ADS ($0.27 per
share), or $530 million based on total shares of common stock outstanding net of treasury shares, be approved at the company’s annual general shareholders’ meeting, which is scheduled to be held on May 6, 2025. Based on current market price of Ternium’s ADS, the proposed annual dividend is equivalent to a dividend yield of 9%.
The annual dividend would include
the interim dividend of $0.90 per ADS ($0.09
per share), or $177 million, paid in the fourth
quarter. If the board of directors’ proposal is
approved at the shareholders’ meeting, a net
dividend of $1.80 per ADS ($0.18 per share), or
$353 million, will be paid on May 14, 2025, with
record date on May 9, 2025.

Outlook
Ternium expects a slight sequential increase in adjusted EBITDA for the first quarter of 2025 driven by improved margins and shipments, with volume recovery in Brazil and stable shipments in Mexico and Argentina. The company anticipates that cost per ton will decrease in the first quarter due to the gradual consumption of lower-priced slabs and raw material inventories, while a sequentially lower revenue per ton is expected to partially offset this cost reduction.
The recent surge in US trade action is creating significant uncertainty in global markets. Within Ternium’s markets, the company anticipates that this development will continue to affect Mexico’s apparent steel demand until a definitive understanding of the final measures is achieved.
Ternium’s new push-pull pickling line at the Pesquería industrial center along with four lines in the new finishing center, all part of the company’s downstream expansion project in Mexico, continue to progress in their ramp-up process. Ternium expects to start-up the remainder of the lines in this project, a cold rolling mill and a hot-dip galvanizing line, by the end of the year.
The company’s newly built wind farm in Argentina commenced electricity generation in December 2024. All of the 22 wind turbines have already been installed. Upon full operation, the wind farm is projected to produce approximately 480 GWh annually, mostly offsetting the company’s procurement of third-party electricity in the country. This initiative provides substantial economic benefits and assists the company in achieving its decarbonization goals.

Steel Segment Fourth Quarter of 2024 Results
In the fourth quarter of 2024, the Steel Segment’s shipments and net sales decreased sequentially by 9% and 14%, respectively. This decline primarily reflects a seasonal activity slowdown, along with a drop in Mexican commercial market demand. Additionally, realized steel prices fell across all of Ternium’s markets.
On a year-over-year basis, the fourth quarter Steel Segment’s shipments and net sales dropped by 7% and 21%, respectively. Sales volumes saw a slight increase in Brazil but declined in other steel markets. Steel prices experienced a year-over-year decrease in all markets.

In Mexico, steel shipments decreased sequentially in the fourth quarter of 2024 due to seasonally lower demand and a weaker commercial market. Compared to the prior-year fourth quarter, shipments also decreased, as the softness in the commercial market was partially offset by the continued growth in Ternium’s sales volumes to industrial customers.
In Brazil, shipments declined sequentially in the fourth quarter primarily due to seasonally lower steel demand. However, year-over-year, sales volumes in this period showed a slight improvement.
In the Southern Region, steel shipments decreased sequentially in the fourth quarter reflecting seasonally lower demand. In an year-over-year comparison, sales volumes decreased in the period due to the negative impact on activity of the Argentine government’s economic stabilization measures.
In Other Markets, sales volumes decreased in the fourth quarter on a sequential and year-over-year basis. The decline was primarily due to lower shipments in the US market.

The Steel Segment’s Cash Operating Income per Ton and Margin decreased both sequentially and year-over-year in the fourth quarter of 2024. In this period, revenue per ton decreased by $57 sequentially and by $177 compared with the prior-year fourth quarter. These declines were partially offset by a
decrease in cost per ton of steel, which, however,
continued to lag behind the reduction in raw material and slab market prices.
In addition, the year-over-year decrease in the cost per ton of steel reflected incremental efficiency gains achieved at Usiminas’ blast furnace operations.

Steel Segment Full Year 2024 Shipments and Net Sales
The Steel Segment’s net sales in 2024 experienced a slight decline compared to 2023. Realized steel prices decreased by 10% year-over-year reflecting the overall market trend. This decline was mostly offset by an
increase in reported shipments, primarily due to the full consolidation of Usiminas’ results partially offset by lower sales volumes in the Southern Region.

In Mexico, sales volumes remained relatively stable year-over-year in 2024. The weakness in the country’s commercial steel market was largely offset by
sustained growth in Ternium’s shipments to industrial customers. Over the past few years, shipments in Mexico have increased significantly.

In Brazil, shipments increased in 2024 due to the full year consolidation of Usiminas’ results. Additionally, sales volumes in the country were bolstered by Usiminas’ enhanced operating performance and stronger local demand for steel products.
In the Southern Region, shipments experienced a significant decrease reflecting the Argentine government’s economic stabilization measures, which had a significant impact in the first quarter followed by a gradual improvement throughout the year.
In Other Markets, sales volumes improved in 2024, albeit starting from relatively weak shipments in 2023.

The Mining Segment’s Cash Operating Income per Ton and Margin increased sequentially in
the fourth quarter of 2024 due to lower operating costs, partially offset by a decrease in
realized iron ore prices. The reduction in operating costs was partly attributed to a lower-priced mix of sales.

Net Financial Results
Net financial results showed a loss of $67 million in the fourth quarter of 2024. In this period, Ternium reported a $72 million net foreign exchange loss, primarily due to the adverse effect of the Brazilian Real’s depreciation against the US dollar on Usiminas’ US dollar denominated liabilities, given that Usiminas uses the Brazilian Real as its functional currency.
For the full year 2024, net financial results showed a loss of $194 million, including the negative impact of the Brazilian Real’s depreciation on Usiminas’ US dollar denominated liabilities. Additionally, net financial results for 2024 reflected a loss of $121 million due to Ternium’s divestment of Argentine government bond holdings, resulting in the recycling of changes in the fair value of financial instruments from Other Comprehensive Income to Financial Results.

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. In addition, in the fourth quarter of 2024 the effective tax rate was influenced by
a provision reversal for ongoing litigation related to the acquisition of a participation in Usiminas; for the full year 2024 it was influenced by a net provision related to the same litigation; and for the full year 2023 it was influenced by certain non-cash effects related to the increase in the participation in Usiminas.

Cash Flow and Liquidity
In the fourth quarter of 2024, cash from operations amounted to $472 million, with a $257 million decrease in working capital. This decrease included a $194 million net reduction in trade and other receivables, mainly due to lower net sales. In addition, inventories decreased by $113 million during the period, primarily due to lower inventory costs, partially offset by higher steel volumes. Conversely,
trade payables and other liabilities saw a net decrease of $49 million in the fourth quarter. Capital expenditures totaled $561 million, primarily reflecting progress in the construction of the new facilities at Ternium’s industrial center in Pesquería, Mexico, as well as the completion of the new wind farm in Argentina.

In 2024, cash from operations reached $1.9 billion, with working capital remaining relatively unchanged year-over-year. Inventories increased by $109 million, as higher steel and raw material inventory volumes were partially offset by lower inventory costs. In addition, trade payables and other liabilities recorded a net decrease of $35 million in 2024. On the other hand, trade and other receivables saw a net decrease of $128 million amid lower realized steel prices.
Capital expenditures amounted to $1.9 billion in 2024. Throughout the year, the company advanced the construction of the new downstream and upstream facilities in its industrial center in Pesquería, Mexico, including the start-up of a new push-pull pickling line and finishing facilities and built a new wind farm in Argentina. Furthermore, the company advanced several projects aimed at further improving environmental and safety conditions throughout its main facilities.
