 litigations related to the acquisition of a participation in Usiminas and a $39 million gain from the positive resolution of legal claims in Mexico and Brazil.

Others

The following table indicates, for our Others business segment, net sales, operating income and operating income as a percentage of net sales for the periods indicated below:

| Others                        |     | 9M 2025 |     | 9M 2024 |     | Increase/(Decrease) |
| Net sales ($ million)         |     |     426 |     |     467 |     | -9%                 |
| Operating income ($ million)  |     |      70 |     |      88 |     | -21%                |
| Operating margin (% of sales) |     |   16.4% |     |   18.9% |     |                     |

Net sales of other products and services decreased 9% to $426 million in the first nine months of 2025, compared to $467 million in the first nine months of 2024. The decline in sales is related to lower sales of sucker rods, coiled tubing and excess raw materials, partially offset by an increase in the sale of oilfield services in Argentina.

Operating results from other products and services amounted to a gain of $70 million in the first nine months of 2025, compared to a gain of $88 million in the first nine months of 2024. Results were mainly derived from our oilfield services business in Argentina and from the sale of sucker rods.

Selling, general and administrative expenses, or SG&A,declined from $1,459 million in the first nine months of 2024 to $1,376 million in the first nine months of 2025. The decline in SG&A expenses is mainly due to a decline in labor costs, provisions for contingencies, taxes and other expenses.

Other operating resultsamounted to a loss of $500 thousands in the first nine months of 2025, compared to a loss of $146 million in the first nine months of 2024. In the first nine months of 2024 we recorded a $174 million loss from provision for ongoing litigation related to the acquisition of a participation in Usim
