Thank you, Mari.

And I would like to say hello to everyone. I hope you're all well. And I certainly appreciate the opportunity to be together for another earnings release. We will briefly comment on the highlights of the quarter. We will also talk about the outlook for our operations. and certainly we will dedicate more time to the Q&A session. But firstly, I would like to highlight that we ended the first quarter of 2025 with an accident frequency rate of 0.61. In the week in which we celebrate World Day for Safety and Health at Work, this results reaffirms our commitment to the health, well-being, and safety of all people. Moreover, we receive IRMA standard recognition, the initiative for responsible mining insurance for our Miguel Brunier iron ore mine located in the municipality of Ouro Preto in the state of Minas Gerais. The operation achieved IRMA performance level 50, highlighting the company's transparency and commitment to sustainability and business integrity. With this, Miguel Bournier joins an exclusive group of only 11 minds worldwide that have completed and received this certification, which is one of the main certifications worldwide. Also in Minas Gerais, in March, we inaugurated the expansion of hot roll coil production capacity in Ouro Branco, increasing the share of flat steel in our portfolio in Brazil, and also enabling Gerdau to offer a wider range of high-value-added products to our customers in the domestic market. This market continued to be strongly impacted by the influx of imported steel in the first three months of the year, when the penetration rate of imported steel reached 22%, up by almost three percentage points when compared to the fourth quarter last year. This data shows that the current quota tariff system remains ineffective ineffective in defending the Brazilian steel industry. I will now hand over to Jean-Paul who will detail the financial highlights.
