In 3R, after the Company’s IPO, Mr. Dias went on to lead the Commercial and New Business areas as a statutory director of the Company’s subsidiaries, being responsible for negotiations related to the acquisition of oil and gas production assets, strategic partnerships, and other relevant contracts. During the year of 2022, Mr. Dias went on to lead the Procurement, Information Technology, Legal and Regulatory areas, as well as the Mid & Downstream areas.
