NextDecade Corporation (NextDecade or the Company) (NASDAQ:NEXT) announced today the appointment of John Zuklic as the Company's new Chief Financial Officer, effective July 6, 2026. Mike Mott, who is currently the Company's Interim Chief Financial Officer, will return to his previous role as Senior Vice President of Enterprise Transformation.

John Zuklic brings significant expertise after more than 30 years in the energy industry, including senior finance roles in capital-intensive businesses. His experience includes financial strategy, capital structuring, treasury, corporate finance, stakeholder engagement, building and transforming organizations, and strengthening governance and risk oversight.

Zuklic joins NextDecade from Citgo Petroleum Corporation (CITGO), where he held the position of Chief Financial Officer since 2020. At CITGO, he led the finance organization and was responsible for setting and executing financial strategy, recapitalizing the company, and building functions to strengthen forecasting, governance, and decision support.

Before his tenure at CITGO, Zuklic spent much of his career at Phillips 66 and its predecessor, ConocoPhillips. During his time at these companies, he progressed through various roles of increasing scope across treasury, corporate finance, risk management, and enterprise transformation. Following the spinoff of Phillips 66 from ConocoPhillips, Zuklic served as Vice President and Treasurer, leading global treasury operations, managing substantial investment and insurance portfolios, and executing enterprise-wide financing initiatives. Later, he served as Vice President of ERP Transformation, where he oversaw the implementation of a next-generation enterprise resource planning system.

"John is an experienced strategic and operational leader, with a strong track record of guiding large energy infrastructure companies through growth and transformation," said Matt Schatzman, NextDecade Chairman and Chief Executive Officer. "I look forward to partnering with John as we transform NextDecade from an LNG development company into an LNG operating company with incredible organic growth opportunities."
