Disclosure of commitments and contingencies [Abstract]
CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS	CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS Ternium is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure. Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Ternium is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, Ternium has not accrued a provision for the potential outcome of these cases. If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Ternium was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Ternium’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss. The Company believes that the aggregate provisions recorded for potential losses in its consolidated financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Ternium could incur a charge to earnings which could have a material adverse effect on Ternium’s results of operations, financial condition, net worth and cash flows. (i) Tax claims and other contingencies The tax claims and other contingencies recognized at the increase of the participation of Usiminas are included in note 3. (a) Provision for ongoing litigation related to the acquisition of a participation in Usiminas The Company is party to a longstanding lawsuit filed in Brazil by Companhia Siderúrgica Nacional, or CSN, and various entities affiliated with CSN against Ternium Investments, its subsidiary Ternium Argentina, and Tenaris’s subsidiary Confab, all of which compose the T/T Group under the Usiminas shareholders agreement. The entities named in the CSN lawsuit had acquired participations in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to the Usiminas control group. Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%. 25. CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued) On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. CSN filed an appeal to the Superior Court of Justice (SCJ), seeking the review and reversal of the decision issued by the Court of Appeals, and on March 7, 2023, the SCJ, by majority vote, rejected CSN’s appeal. CSN made several submissions in connection with the SCJ decision, including a motion for clarification that challenged the merits of the SCJ decision. Decisions at the SCJ are adopted by majority vote. At an October 17, 2023 session, two justices of the SCJ voted in favor of remanding the case to the first instance for it to be retried following production and assessment of the new evidence, and two justices of the SCJ voted, without requiring any further evidence, in favor of granting CSN’s motion for clarification and reversing the March 7, 2023 decision that rejected CSN’s appeal; because the fifth member of SCJ excused himself from voting, a justice from another panel at the SCJ was summoned to produce the tie-breaking vote. On June 18, 2024, the SCJ completed its voting on CSN’s motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and resolved that Ternium Investments, its subsidiary Ternium Argentina and Tenaris’s subsidiary Confab should pay CSN an indemnification in connection with the acquisition by the T/T Group of the participations in Usiminas in January 2012, with CSN being allowed to retain ownership of the Usiminas ordinary shares it currently owns. On August 1, 2024, Ternium Investments, Ternium Argentina and the other T/T Group entities filed a motion for clarification against the SCJ decision and, subsequently, CSN filed its reply. On December 6, 2024, the SCJ rejected this motion for clarification, confirming the obligation of the T/T Group entities to pay indemnification in connection with the 2012 acquisition of the participations in Usiminas. Notwithstanding the foregoing, the SCJ unanimously resolved to modify the applicable monetary adjustment mechanism and to cap the applicable attorney’s fees, thereby lowering the aggregate amount that would be payable if CSN ultimately prevails in this claim. Based on such SCJ decision, assuming monetary adjustment thorough December 31, 2024, and attorney’s fees in the amount of BRL5 million, the revised aggregate amount potentially payable by Ternium Investments and Ternium Argentina if CSN finally prevails on its claims would be of approximately BRL1,875.9 million (approximately $302.9 million at the BRL/$ rate as of such date) and BRL664.1 million (approximately $107.3 million at the BRL/$ rate as of such date), respectively. The Company continues to believe that all of CSN's claims and allegations are unsupported and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator in February 2012 and December 2016, the first and second instance court decisions and the March 7, 2023 SCJ decision referred to above, and that in connection with the Usiminas acquisition the T/T Group was not required either to launch a tender offer or to pay indemnification to CSN. Accordingly, on February 10, 2025, Ternium filed an extraordinary appeal against the SCJ decisions that ordered an indemnification payment, seeking their review and reversal by the Supreme Federal Tribunal. The Company, however, cannot predict the ultimate resolution on the matter. 25. CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued) (b) Potential Mexican income tax adjustment In March 2015, as part of a tax audit with respect to fiscal year 2008, the Mexican tax authority ("SAT") challenged the deduction by Ternium Mexico of a tax loss arising from an intercompany sale of shares in December 2008. In addition, in September 2018, as part of a tax audit for fiscal year 2011, the SAT objected to the deduction by Ternium Mexico of the remainder of the 2008 tax loss. Ternium Mexico requested an injunction from the Mexican courts against the SAT claims and filed its defense and supporting documents with the SAT. After Ternium Mexico obtained an injunction in August 2020, in November 2020 the SAT issued a new preliminary audit report in which it reiterated its objections to the deduction of the 2008 tax loss. In June 2021, the SAT determined income tax adjustments with respect to 2008 and 2011 for amounts currently estimated at approximately $72.8 million and $35.6 million, respectively. Ternium Mexico appealed the SAT determinations. More recently, however, Ternium Mexico withdrew its appeals and agreed to provide further information and documentation to the SAT. With all of the above-mentioned information and documentation, the SAT reduced the 2008 and 2011 tax adjustments downwards to approximately $17.5 million and $35.8 million, respectively. The Company had a tax provision of $53.3 million already included in its consolidated condensed interim financial statements as of September 30, 2023. The payment to the SAT was done on October 9, 2023, and the Company received formal documentation issued by the SAT with the closure of both audits. (c) Tax assessments relating to the use of certain ICMS tax credits The Imposto Sobre Operações Relativas à Circulação de Mercadorias e Serviços, or ICMS, is a Brazilian value-added tax on the services (inter-states) and the transfer of goods in Brazil. Payment of ICMS generates tax credits that, subject to applicable law, rules and regulations, may be either used to offset ICMS payment obligations generated in connection with domestic sales of products and services, or sold and transferred to third parties. The Rio de Janeiro State Treasury Office is challenging the use by Ternium Brasil of ICMS tax credits generated in connection with purchases of refractory materials in the period from December 2010 through December 2016, and intends to assess taxes and impose fines on Ternium Brasil on the argument that such materials may not be qualified as “raw materials” or “intermediary products” but as “goods for consumption” and, accordingly, ICMS tax credits generated in connection with their purchase are not available and may not be used to offset ICMS payment obligations generated in connection with Ternium Brasil’s domestic sales of carbon steel slabs. Ternium Brasil has appealed against the Rio de Janeiro State Treasury Office tax assessments and fines. A provision in the amount of $57.7 million was recorded as of the acquisition date in connection with this matter ($29.3 million and $37.5 million as of December 31, 2024 and 2023, respectively). 25. CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued) (d) BP Energía México (BPEM) – Arbitration process On February 2022, BP Energía México (“BPEM”) started an arbitration process against Gas Industrial de Monterrey, S.A. de C.V. (“GIMSA”), Ternium México and Ternium Gas México (“Respondents”), claiming payment for the gas supply from February 12 to February 28, 2021, for $27.6 million, $12.4 million, and $2.4 million, plus V.A.T. and interest, respectively. On June 9, 2024, after the arbitration process was completed, the arbitration award was notified and the Arbitration Tribunal ordered the Respondents to pay BPEM $22.0 million, $9.9 million and $2.1 million, plus V.A.T. and interest, respectively. Additionally, the Parties were ordered to pay expenses and costs for $2.4 million. As of September 30, 2024, the Company recognized a provision of $34.2 million in its consolidated condensed interim financial statements. On October 25, 2024, the parties reached an agreement settling the reciprocal claims, and all parties formally dismissed the legal actions initiated with respect to the arbitration award. (e) PIS and COFINS credits defense action - Usiminas In August 2024, the Federal Government had filed two new tax claims for a total of approximately BRL 503 million ($92 million; BRL518 million or $84 million as of December 31, 2024). The contingencies are related to tax assessments that partially approved offset statements through which Usiminas claimed PIS and COFINS credits arising from a final court decision, which discussed the exclusion of ICMS from the calculation basis of said contributions. The tax authority disagreed with the calculation methodology adopted by Usiminas. Usiminas filed a defense action in the aforementioned proceedings, arguing that the calculations are correct and the credit rights should be recognized. (ii) Commitments The following are Ternium’s main off-balance sheet commitments: (a) Ternium Argentina signed agreements, mainly with Vale S.A. and Mineração Corumbaense Reunida S.A., to cover 80% of its required iron ore, pellets and iron ore fines volumes until December 31, 2024, having no residual value as of such date. Although they do not set a minimum amount or a minimum commitment to purchase a fixed volume, under certain circumstances a penalty is established for the party that fails of: - 7% in case the annual operated volume is between 70% and 75% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases. - 15% in case the annual operated volume is lower than 70% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases. 25. CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued) (b) Ternium Argentina also signed various contracts for the provision and transportation of natural gas, including Tecpetrol and Energy Consulting Services S.A., both related companies of Ternium, assuming firm commitments for a total of $10.2 million payable until April 2025. Additionally, Ternium Argentina signed contracts for gas transportation with Transportadora de Gas del Norte S.A., a related company of Ternium, assuming firm commitments for a total of $28.5 million payable until April 2028. (c) Ternium Argentina signed an agreement with Air Liquide Argentina S.A. for the supply of oxygen, nitrogen and argon, for an aggregate amount of $58.8 million, which is due to terminate in 2037. (d) Ternium Argentina signed various contracts within its investment plan for the future acquisition of Property, plant and equipment for a total of $35.8 million. Also, Vientos de Olavarría, a subsidiary controlled by Ternium Argentina, subscribed various contracts for the maintenance and the operation of the wind farm for a total of $62.0 million payable until the year 2054. (e) On April 24, 2017, Ternium Mexico entered into a 25-year contract (effective as of December 1, 2016, through December 1, 2041) with Techgen, S.A. de C.V. for the supply of 699 MW (which represents 78% of Techgen’s capacity) and covers most of Ternium Mexico’s facilities electricity needs. Monthly payments are determined on the basis of capacity charges, operation costs, back-up power charges, and transmission charges. As of the seventh contract year (as long as Techgen’s existing or replacing bank facility has been repaid in full), Ternium Mexico has the right to suspend or early terminate the contract if the rate payable under the agreement is higher than the rate charged by Comisión Federal de Electricidad (“CFE”) or its successors. Ternium Mexico may instruct Techgen to sell to any affiliate of Ternium Mexico, to CFE, or to any other third party all or any part of unused contracted energy under the agreement and Ternium Mexico will benefit from the proceeds of such sale. The contract with Techgen is under the Self Supply Scheme. According to this regulatory scheme, CFE needs to authorize the sale of energy to other third party final users. On August 27, 2021, Ternium México and Techgen signed an amendment to the contract to establish changes in the supply to Ternium; these changes were mainly connected to a new direct transmission line between Techgen and Ternium's Pesqueria Site for the direct supply of electricity to this site. (f) Ternium México issued a guarantee letter covering up to approximately $28.8 million of the obligations of Gas Industrial de Monterrey, S.A. de C.V. (“GIMSA”), under the natural gas trading agreement between GIMSA and NEG Natural S.A. de C.V. (“NEG”). The credit line granted by NEG in connection with this natural gas trading agreement amounted to approximately $19.1 million. As of December 31, 2024, the outstanding amount under the natural gas trading agreement was $9.5 million, which is below the amount included in the guarantee letter issued by Ternium México. (g) Ternium Mexico issued a guarantee letter covering up to approximately $58.7 million of the obligations of Techgen S.A. de C.V. ("Techgen") under the Clean Energy Certificates trading agreement between Techgen and Enel Green Power ("ENEL"). The amount equals the remnant balance if Techgen decides to terminate the agreement prior to the expiration date (and decreases as time of the contract passes). The contract was signed on May 25, 2018, and terminates on June 30, 2041. 25. CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued) (h) In June 2008, Ternium Mexico entered into an industrial gas supply agreement with Praxair Mexico for the Guerrero and Juventud facilities until December 2024, for a total amount of $421 million. In 2011, an amendment agreement added the purchase of hydrogen for the Juventud and Universidad facilities, valid until April 2025. As of December 31, 2024, the agreement considers a minimum annual oxygen consumption of 96 million cubic meters, valued at approximately $4.5 million per year. The Company is in compliance with the minimum annual quotas established, which represent less than half of the average annual consumption. (i) On May 9, 2018, Ternium Mexico entered into a 10-year contract (effective as of July 1, 2018) with Kinder Morgan Texas Pipeline L.L.C., Kinder Morgan Tejas Pipeline L.L.C. and Kinder Morgan Border Pipeline L.L.C. for the transportation of natural gas in the United States of America (Texas). The contracted capacity is 60,000 MMBTU/day and the annual cost is approximately $3.7 million. (j) On December 30, 2019, Ternium Mexico entered into a 15-year contract (effective as of July 1, 2021) with Kinder Morgan Texas Pipeline L.L.C., Kinder Morgan Tejas Pipeline L.L.C. and Kinder Morgan Gas Natural de México S. de R.L. de C.V. for the transportation of natural gas in the United States of America (Texas) and in Mexico. The contracted capacity is 31,000 MMBTU/day and the annual cost is approximately $4.8 million. (k) In February 2023, Ternium's Board of Directors approved a new project in Pesquería, which involves the construction of an electric arc furnace and a direct reduced iron plant. As of December 31, 2024, Ternium México has commitments for property, plant and equipment for an amount of approximately $1.3 billion in Euros, Mexican pesos, Japanese yens, and U.S. dollars. These commitments are mainly covered by currency derivative financial instruments as commented in note 22 in these Consolidated Financial Statements. (l) Techgen is a party to gas transportation capacity agreements with Kinder Morgan Gas Natural de Mexico, S. de R.L. de C.V., Kinder Morgan Texas Pipeline LLC and Kinder Morgan Tejas Pipeline LLC for the whole transportation capacity starting on August 1, 2016 and ending during the second half of 2036. As of December 31, 2024, the outstanding value of this commitment was approximately $164.8 million. Ternium’s exposure under the guarantee in connection with these agreements amounts to $79.1 million, corresponding to the 48% of the agreements’ outstanding value as of December 31, 2024. (m) Ternium issued two stand-by letters of credit covering 48% of the funding of a debt service reserve account under a syndicated loan agreement between Techgen and several banks led by Citigroup Global Markets Inc., Credit Agricole Corporate and Investment Bank, and Natixis, New York Branch acting as joint bookrunners. The loan agreement dated as of February 13, 2019, amounted to $640 million and the proceeds were used by Techgen to refinance in full all amounts owed under a previous syndicated loan between Techgen and several banks, which funds were used in the construction of the facility. As of December 31, 2024, the outstanding aggregated amount under the stand-by letters of credit was $49.6 million, as a result the amount guaranteed by Ternium was approximately $23.8 million. 25.

(s) Ternium Brasil signed on January 2015 a contract with Naturgy (formerly Companhia Distribuidora de Gás do Rio de Janeiro) for the supply of natural gas, which was due to terminate in December 2019. This agreement was automatically renewed for another two years, was due to terminate in December 2024 and could be interrupted by common agreement due to free market conditions' changes. Ternium Brasil was purchasing more than the minimum volume required by the contract, which is 85% of the volume mentioned before. The contract was terminated in September 2024 without penalty. (t) Ternium Brasil signed in December 2023 a contract with Vix Logística S.A. for logistics supply chain operations. This agreement is due to terminate in December 2028 and the outstanding amount was $33.6 million as of December 31, 2024.

On October 15, 2012, the agreement was authorized by the National Mining Agency (ANM). It has a duration of 30 years, or until the complete depletion of these mineral reserves. The monthly payments are linked to the volume of iron ore extracted from the areas covered by the agreement. Since 2015, a minimum annual volume of 3.6 million metric tons was established. If the annual volume of iron ore extracted is below the minimum volume, a payment under a take-or-pay arrangement will be due, calculated as the difference between the minimum volume and the volume effectively extracted. The outstanding amount was approximately $261.1 million as of December 31, 2024. (y) In June 2016, Usiminas S.A. entered into electricity purchase agreement with Cemig S.A. for the Cubatão steel plant facilities until December 2030.

(an) Mineração Usiminas S.A. signed in September 2023 an agreement with Armac Locação Logistica e Serviços S.A. for the supply of internal material handling services from the Ouro Negro area until November 2026. The contract has a termination clause with a termination penalty of 50% of the remaining value of the contract from the 13th to the 21st month, 25% of the remaining value from the 22nd to the 24th month and no penalty from the 25th to the 36th month with 60 days' notice. The outstanding amount was approximately $20.4 million as of December 31, 2024. (iii) Restrictions on the distribution of profits In accordance with Luxembourg Law, the Company is required to transfer a minimum of 5% of its net profit for each financial year to a legal reserve until such reserve equals 10% of the issued share capital. As of December 31, 2024, this reserve is fully allocated and additional allocations to the reserve are not required under Luxembourg law. Dividends may not be paid out of the legal reserve. The Company may pay dividends to the extent, among other conditions, that it has distributable retained earnings calculated in accordance with Luxembourg law and regulations.

Ternium is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure.

Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Ternium is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, Ternium has not accrued a provision for the potential outcome of these cases.

If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Ternium was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Ternium’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.

The Company believes that the aggregate provisions recorded for potential losses in its consolidated financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Ternium could incur a charge to earnings which could have a material adverse effect on Ternium’s results of operations, financial condition, net worth and cash flows.

The Company is party to a longstanding lawsuit filed in Brazil by Companhia Siderúrgica Nacional, or CSN, and various entities affiliated with CSN against Ternium Investments, its subsidiary Ternium Argentina, and Tenaris’s subsidiary Confab, all of which compose the T/T Group under the Usiminas shareholders agreement. The entities named in the CSN lawsuit had acquired participations in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to the Usiminas control group. Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. CSN filed an appeal to the Superior Court of Justice (SCJ), seeking the review and reversal of the decision issued by the Court of Appeals, and on March 7, 2023, the SCJ, by majority vote, rejected CSN’s appeal.

CSN made several submissions in connection with the SCJ decision, including a motion for clarification that challenged the merits of the SCJ decision. Decisions at the SCJ are adopted by majority vote. At an October 17, 2023 session, two justices of the SCJ voted in favor of remanding the case to the first instance for it to be retried following production and assessment of the new evidence, and two justices of the SCJ voted, without requiring any further evidence, in favor of granting CSN’s motion for clarification and reversing the March 7, 2023 decision that rejected CSN’s appeal; because the fifth member of SCJ excused himself from voting, a justice from another panel at the SCJ was summoned to produce the tie-breaking vote. On June 18, 2024, the SCJ completed its voting on CSN’s motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and resolved that Ternium Investments, its subsidiary Ternium Argentina and Tenaris’s subsidiary Confab should pay CSN an indemnification in connection with the acquisition by the T/T Group of the participations in Usiminas in January 2012, with CSN being allowed to retain ownership of the Usiminas ordinary shares it currently owns.

On August 1, 2024, Ternium Investments, Ternium Argentina and the other T/T Group entities filed a motion for clarification against the SCJ decision and, subsequently, CSN filed its reply. On December 6, 2024, the SCJ rejected this motion for clarification, confirming the obligation of the T/T Group entities to pay indemnification in connection with the 2012 acquisition of the participations in Usiminas. Notwithstanding the foregoing, the SCJ unanimously resolved to modify the applicable monetary adjustment mechanism and to cap the applicable attorney’s fees, thereby lowering the aggregate amount that would be payable if CSN ultimately prevails in this claim. Based on such SCJ decision, assuming monetary adjustment thorough December 31, 2024, and attorney’s fees in the amount of BRL5 million, the revised aggregate amount potentially payable by Ternium Investments and Ternium Argentina if CSN finally prevails on its claims would be of approximately BRL1,875.9 million (approximately $302.9 million at the BRL/$ rate as of such date) and BRL664.1 million (approximately $107.3 million at the BRL/$ rate as of such date), respectively.

The Company continues to believe that all of CSN's claims and allegations are unsupported and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator in February 2012 and December 2016, the first and second instance court decisions and the March 7, 2023 SCJ decision referred to above, and that in connection with the Usiminas acquisition the T/T Group was not required either to launch a tender offer or to pay indemnification to CSN. Accordingly, on February 10, 2025, Ternium filed an extraordinary appeal against the SCJ decisions that ordered an indemnification payment, seeking their review and reversal by the Supreme Federal Tribunal. The Company, however, cannot predict the ultimate resolution on the matter.

In March 2015, as part of a tax audit with respect to fiscal year 2008, the Mexican tax authority ("SAT") challenged the deduction by Ternium Mexico of a tax loss arising from an intercompany sale of shares in December 2008. In addition, in September 2018, as part of a tax audit for fiscal year 2011, the SAT objected to the deduction by Ternium Mexico of the remainder of the 2008 tax loss. Ternium Mexico requested an injunction from the Mexican courts against the SAT claims and filed its defense and supporting documents with the SAT. After Ternium Mexico obtained an injunction in August 2020, in November 2020 the SAT issued a new preliminary audit report in which it reiterated its objections to the deduction of the 2008 tax loss. In June 2021, the SAT determined income tax adjustments with respect to 2008 and 2011 for amounts currently estimated at approximately $72.8 million and $35.6 million, respectively. Ternium Mexico appealed the SAT determinations.

More recently, however, Ternium Mexico withdrew its appeals and agreed to provide further information and documentation to the SAT. With all of the above-mentioned information and documentation, the SAT reduced the 2008 and 2011 tax adjustments downwards to approximately $17.5 million and $35.8 million, respectively. The Company had a tax provision of $53.3 million already included in its consolidated condensed interim financial statements as of September 30, 2023. The payment to the SAT was done on October 9, 2023, and the Company received formal documentation issued by the SAT with the closure of both audits.

The Imposto Sobre Operações Relativas à Circulação de Mercadorias e Serviços, or ICMS, is a Brazilian value-added tax on the services (inter-states) and the transfer of goods in Brazil. Payment of ICMS generates tax credits that, subject to applicable law, rules and regulations, may be either used to offset ICMS payment obligations generated in connection with domestic sales of products and services, or sold and transferred to third parties.

The Rio de Janeiro State Treasury Office is challenging the use by Ternium Brasil of ICMS tax credits generated in connection with purchases of refractory materials in the period from December 2010 through December 2016, and intends to assess taxes and impose fines on Ternium Brasil on the argument that such materials may not be qualified as “raw materials” or “intermediary products” but as “goods for consumption” and, accordingly, ICMS tax credits generated in connection with their purchase are not available and may not be used to offset ICMS payment obligations generated in connection with Ternium Brasil’s domestic sales of carbon steel slabs. Ternium Brasil has appealed against the Rio de Janeiro State Treasury Office tax assessments and fines. A provision in the amount of $57.7 million was recorded as of the acquisition date in connection with this matter ($29.3 million and $37.5 million as of December 31, 2024 and 2023, respectively).

On February 2022, BP Energía México (“BPEM”) started an arbitration process against Gas Industrial de Monterrey, S.A. de C.V. (“GIMSA”), Ternium México and Ternium Gas México (“Respondents”), claiming payment for the gas supply from February 12 to February 28, 2021, for $27.6 million, $12.4 million, and $2.4 million, plus V.A.T. and interest, respectively. On June 9, 2024, after the arbitration process was completed, the arbitration award was notified and the Arbitration Tribunal ordered the Respondents to pay BPEM $22.0 million, $9.9 million and $2.1 million, plus V.A.T. and interest, respectively. Additionally, the Parties were ordered to pay expenses and costs for $2.4 million. As of September 30, 2024, the Company recognized a provision of $34.2 million in its consolidated condensed interim financial statements.

In August 2024, the Federal Government had filed two new tax claims for a total of approximately BRL 503 million ($92 million; BRL518 million or $84 million as of December 31, 2024). The contingencies are related to tax assessments that partially approved offset statements through which Usiminas claimed PIS and COFINS credits arising from a final court decision, which discussed the exclusion of ICMS from the calculation basis of said contributions. The tax authority disagreed with the calculation methodology adopted by Usiminas. Usiminas filed a defense action in the aforementioned proceedings, arguing that the calculations are correct and the credit rights should be recognized.

(a) Ternium Argentina signed agreements, mainly with Vale S.A. and Mineração Corumbaense Reunida S.A., to cover 80% of its required iron ore, pellets and iron ore fines volumes until December 31, 2024, having no residual value as of such date.

Monthly payments are determined on the basis of capacity charges, operation costs, back-up power charges, and transmission charges. As of the seventh contract year (as long as Techgen’s existing or replacing bank facility has been repaid in full), Ternium Mexico has the right to suspend or early terminate the contract if the rate payable under the agreement is higher than the rate charged by Comisión Federal de Electricidad (“CFE”) or its successors. Ternium Mexico may instruct Techgen to sell to any affiliate of Ternium Mexico, to CFE, or to any other third party all or any part of unused contracted energy under the agreement and Ternium Mexico will benefit from the proceeds of such sale. The contract with Techgen is under the Self Supply Scheme. According to this regulatory scheme, CFE needs to authorize the sale of energy to other third party final users. On August 27, 2021, Ternium México and Techgen signed an amendment to the contract to establish changes in the supply to Ternium; these changes were mainly connected to a new direct transmission line between Techgen and Ternium's Pesqueria Site for the direct supply of electricity to this site.
