CITGO Appoints Catarina Collins Serra as Interim CFO

In a significant organizational shift, CITGO Petroleum Corporation has announced the appointment of Catarina Collins Serra as its interim Chief Financial Officer (CFO). Serra succeeds John Zuklic, who has served in this role for nearly six years. This change was officially communicated on June 17, 2026, marking an important transition for the financial leadership of the company.

Carlos Jordá, CITGO's President and CEO, expressed confidence in Serra's capabilities, highlighting her vast experience in financial management within the industrial and energy sectors. Serra's impressive career includes senior roles at renowned companies such as Honeywell, SABIC, GE Power Conversion, and GE Oil & Gas. Her extensive background encompasses global financial controllership, financial planning, analysis, and business transformation initiatives. This makes her well-suited to advance CITGO's financial discipline and operational performance.

Jordá also took the opportunity to acknowledge Zuklic's contributions to the company. His leadership over the past years has been pivotal, steering CITGO through a crucial phase of development. As Zuklic departs from the company, his influence and insights into the financial landscape have set a strong foundation for Serra's leadership.

Catarina Collins Serra holds a Bachelor of Science in Economics from the Universidade Católica Portuguesa and has completed several prominent programs, including GE's Financial Management Program and its Corporate Audit Staff Leadership Program. She is also Six Sigma Green Belt certified, indicating her commitment to operational excellence.

The appointment comes at a time when CITGO is focused on enhancing its operational efficiency and aligning its long-term business goals. As one of the leading independent refiners in the United States, CITGO operates three refineries and manages numerous terminals and pipelines.

CITGO's future remains bright, with a combined crude capacity nearing 829,000 barrels per day. Serra's expertise will be integral to navigating financial challenges while seizing opportunities within the ever-evolving energy landscape. The company continues to emphasize its commitment to providing quality transportation fuels, lubricants, and petrochemicals from its established network of nearly 4,000 independently operated retail outlets.

With Serra at the helm of financial strategy, CITGO aims to reinforce its market position and innovate for the future. As the industry evolves, so too must the leaders at the forefront of these companies. Serra's appointment signals a dedication to marrying experience with strategic foresight to ensure sustainable growth and success.

As we look forward to the new directions CITGO will embark upon under Serra's tenure, the commitment to excellence and innovation remains steadfast. Transitioning leadership roles often brings fresh perspectives, and Serra's wealth of knowledge will undoubtedly be a catalyst for future initiatives at CITGO.
