Ternium supplies steel used in buildings, vehicles, appliances and other manufactured goods, primarily in Latin America and the southern United States. Mexico is its largest sales market, followed by Brazil; Argentina is also important. It makes steel and processes its own and purchased semi-finished steel into sheets, coated steel and other products suited to customers’ requirements. Ternium Brasil supplies slabs for further processing at the group’s Mexican and Argentine plants, as well as for sale to outside customers. Delivery and inventory-management services support these steel sales, and most customer orders pass through Ternium Activo.
Steel provides the vast majority of revenue. Ternium’s mines also supply its steel plants and sell iron ore externally. Mineração Usiminas mainly sells ore to Chinese steel producers, while the Mexican mines mainly serve Ternium’s own facilities.
Earnings depend on steel selling prices relative to the cost of slabs, raw materials and energy. Vale supplies most of the iron ore bought by Ternium Argentina and Ternium Brasil, and Techgen supplies most of the electricity needed by Ternium’s Mexican facilities. Many Mexican customers manufacture goods for export to the United States, tying demand to that trade. U.S. tariffs and steel trade remedies restrict market access, while steelmaking and mining require environmental permits and authorizations.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
ArcelorMittal competes with Ternium for steel sales to construction and industrial customers in Mexico and Brazil, but also shares its Mexican iron-ore supply. Each owns half of Peña Colorada, and Ternium must buy half the mine’s annual output for its Mexican plants.
Gerdau challenges Ternium’s Usiminas in Brazilian steel and Ternium Mexico through Gerdau Corsa in products such as rebar and wire rod. Its Brazilian sales of hot-rolled coils and heavy plate offer a comparison for Usiminas, while its construction-steel business overlaps Ternium’s Mexican customers.
CSN competes with Ternium’s Usiminas for Brazilian flat-steel customers, including construction and appliance businesses, and is also its opponent in the Usiminas acquisition lawsuit. Watch that case: CSN won a June 2024 ruling, but Ternium appealed and a decision remained pending.
Nucor competes with Ternium for customers buying flat steel in Mexico and the United States. Its steel-mill sales are the relevant comparison, rather than its raw-materials business; Mexico accounted for 48% of Ternium’s consolidated net steel-product sales in 2025.
Steel Dynamics competes for flat-steel orders in Ternium’s markets as a major foreign supplier. Its steel-product sales are the business to compare with Ternium’s steel sales, not its recycled-metal, steel-joist or aluminum businesses.
Grupo Simec competes with Ternium Mexico for orders for rebar, wire rod and other long-steel products. Its Mexican rebar and structural-steel sales are the relevant comparison for Ternium’s business serving construction customers, not its U.S. plants, which stopped production in 2023.
Cleveland-Cliffs competes with Ternium for flat-steel customers in overlapping markets, making and finishing steel to buyers’ specifications. Its steelmaking results provide the closer comparison for Ternium’s steel sales than its tooling, stamping or tubing businesses.
POSCO Holdings’ steel operations compete with Ternium for Mexican flat-steel customers and through exports, while both face global steel-price pressure. Watch the average selling price of steel its subsidiaries sell directly to outside customers: it fell in 2025 as global steel markets weakened, a relevant comparison because Ternium’s prices generally follow international prices adjusted for regional conditions.
Tenaris buys coils and plates from Ternium Argentina and Usiminas to make welded pipes, so that production creates demand for Ternium’s steel. It also held 11.46% of Ternium’s shares and voting rights as of February 27, 2026; watch its welded-pipe production in Argentina and Brazil for the purchasing link.
Ternium’s Brazilian and Argentine steel plants depend on iron ore supplied by Vale and other miners under long-term agreements priced to market conditions. Vale’s iron-ore and pellet business is the part to watch for this supply and cost exposure, rather than its nickel and copper operations.
Commercial Metals competes with Ternium in Mexican long steel, selling products such as rebar to construction and fabricating customers. Its construction-steel orders offer a demand comparison, but many fabricated-rebar project prices stay fixed for the project’s life, so they need not track current steel prices.
Housing Starts (Sep)
Ternium sells steel to construction customers, and its filing linked weak construction activity to lower Mexican shipments, so readings on homebuilding help show whether this market may support or restrain steel sales.
Expected1.31MLast release1.275M
If it comes in above expectations
If the reading is above the 1.31M estimate, it is above the previous 1.275M. More homes started, permitted or sold than expected indicate stronger homebuilding, which may increase construction customers’ steel needs and support Ternium’s shipments.
If it comes in below expectations
Fewer homes started, permitted or sold than expected indicate weaker homebuilding, which may reduce construction customers’ steel needs and weigh on Ternium’s shipments.
POSCO Holdings Inc. earningsPKX
POSCO Holdings’ steel selling prices offer a signal on international steel pricing, a reference for the pricing environment Ternium faces.
Watch the average selling price of steel POSCO’s subsidiaries sell to outside customers, and compare it with Ternium’s steel revenue per ton; products and regions differ, so the figures are not directly interchangeable. A POSCO price recovery would suggest a firmer international pricing backdrop for Ternium, though regional discounts and product mix can still create a gap. A further decline would signal continued global price pressure. The takeaway is the direction of the broader price environment, not a guaranteed move in Ternium’s prices.
Durable Goods Orders MoM (Sep)
Ternium sells steel to automotive, packaging and other industrial customers, so orders for long-lasting goods and equipment can signal whether these buyers may purchase more steel and lift shipments or pull back.
Expected0.2%Last release-0.1%
If it comes in above expectations
If the reading is above the 0.2% estimate, it is above the previous -0.1%. More orders than expected point to stronger demand for manufacturers and business investment, which may lead Ternium’s industrial customers to buy more steel and increase its shipments.
If it comes in below expectations
Fewer orders than expected point to weaker demand and investment, which may lead Ternium’s industrial customers to buy less steel and reduce its shipments.
VALE S.A. earningsVALE
Vale supplies some of the iron ore used by Ternium’s Brazilian and Argentine plants, so its report can show how supply and pricing conditions for that input are changing.
Read Vale’s iron-ore and pellet supply, sales and pricing information alongside the needs of Ternium’s Brazilian and Argentine plants. Smooth supply and easing price pressure would reduce one input-cost risk for those plants; tighter supply or higher prices could raise costs or make procurement harder. Long-term agreements, market-based pricing and other miners also affect what Ternium actually pays. The conclusion is whether iron-ore supply is helping or pressuring those steel plants.
Ternium S.A. earningsThis company
Ternium earns mainly by selling steel, and this report will show whether shipment volumes and revenue per ton can improve enough to lift profit.
Read steel shipments, revenue per ton and the Steel segment’s profit margin together. Higher shipments or revenue per ton alongside a steadier margin would show that improving demand or prices are reaching profit. If shipments and revenue per ton remain weak and the margin does not hold, steel-price and volume pressure is still outweighing cost savings. The conclusion is whether steel sales are turning into steadier profit.
Tenaris S. A. earningsTS
Tenaris uses coils and plates bought from Ternium Argentina and Usiminas to make welded pipes, so its production offers a read on demand through this customer link.
Watch Tenaris’s welded-pipe production in Argentina and Brazil alongside steel sales to customers by Ternium Argentina and Usiminas. Higher pipe production suggests stronger potential demand from this customer for coils and plates; lower production could mean less demand through this sales channel. Inventory and purchasing timing still affect actual orders. The takeaway is whether demand from this customer link is strengthening or weakening.
Industrial Production MoM (Oct)
Ternium sells steel to manufacturers and processors, and weaker industrial demand contributed to lower Mexican shipments in 2025, so factory, mine and utility activity can signal whether buyers may take more steel and support shipments.
Rising output and capacity use suggest stronger activity among industrial buyers, which may support their steel purchases from Ternium; falling activity suggests weaker demand and may weigh on shipments.
