Veteran Petroleum Engineer Brings More Than 45 Years of Industry Experience, Specifically Gulf Coast Oil and Gas, to Help Advance the Company’s Platform

Expion Positioned at Attractive Entry Point as Louisiana Takes Steps to Become a Major Hub for Hyperscalers as it Secures Large Data Center and Infrastructure Projects and Drives Demand for Natural Gas

REDMOND, Ore., Aug. 31, 2026 (GLOBE NEWSWIRE) -- Expion Energy, Inc., formerly known as Expion360 Inc. (Nasdaq: XPON) (“Expion” or the “Company”), a leader in energy storage solutions and delivery that is entering the oil and gas sector to capture rising demand driven by power generation needs, industrial growth, and long-term expansion of LNG markets, today announced that its Board of Directors has appointed Marc W. Jarvis as a director, effective August 28, 2026.

The appointment follows the Company’s recent announcements of the appointments of Kevin Sellers as Chief Executive Officer and Robert “Bob” Winspear as Chief Financial Officer, and the establishment of an oil and gas platform beginning in Eastern Louisiana. The prospect is strategically positioned near hyperscale AI data center development and power demand with direct access to Gulf Coast LNG infrastructure.

Mr. Jarvis is a seasoned oil and gas executive who brings more than four decades of executive, management and technical expertise with both public companies and independents within the oil and gas industry, including Deep Tuscaloosa assets in Louisiana. Mr. Jarvis has an extensive background in corporate planning, risk determination, modern portfolio modeling and SEC reserve reporting. He has played key roles in the structuring, valuation, negotiation and closing of more than $2.5 billion dollars of acquisitions and divestitures in the oil and gas sector.

Mr. Jarvis is a Partner at Cynergy Advisors, LLC, a consulting firm providing transaction and investment banking services to clients in the oil and gas industry since 2009. Prior to joining Cynergy in 2020, Mr. Jarvis served as the Executive Vice President, Exploration & Production, of Falcon V, LLC, a New Orleans-based private equity backed oil and gas company focused on Deep Tuscaloosa assets, from 2016 to 2019. From 2011 to 2015, Mr. Jarvis served as Senior Vice President, Engineering, and later Executive Vice President, Exploration & Production, of Summit Discovery Resources LLC, a wholly owned subsidiary of Sumitomo Corporation of Japan, where he was responsible for managing operations, reservoir engineering and geologic departments overseeing an asset base valued at over $1.8 billion and consisting of 730,000 gross acres. From 2005 to 2011, Mr. Jarvis was the Owner and Manager of Skyline Oil & Gas LLC, a Houston-based exploration and development company that originated joint ventures and service contracts. From 1999 to 2005, Mr. Jarvis served as Director of Engineering & Corporate Planning and Director of Acquisitions at Penn Virginia Oil & Gas Corporation, playing a key role in expanding the Gulf Coast Division, executing over $160 million in acquisitions. Mr. Jarvis holds an A.S. and B.S. in Petroleum Engineering Technology from Oklahoma State University.

“Marc has spent more than four decades doing what Expion is now setting out to do – finding, evaluating, structuring and developing oil and gas assets – and he has performed much of that work along the Gulf Coast,” said Kevin Sellers, Chief Executive Officer of Expion Energy. “Marc has built and led multiple exploration and production companies and those skills will be instrumental to Expion as we seek to unlock value from our platform. As we advance our Eastern Louisiana prospect toward drilling and testing, along with evaluating additional opportunities both within and outside our prospect, Marc’s technical expertise and capital markets experience will make us a more disciplined operator and a stronger acquirer.”

Mr. Jarvis added, “The demand backdrop for natural gas in this part of the country is as compelling as I have seen with continued growth of hyperscale data center power demand and Gulf Coast LNG export capacity pulling from the same supply. Both the state of Louisiana and local governments have announced a desire to expand in the LNG market and pursue investments in the hyperscale environment. Major AI and high-performance computing projects in the state have already been announced by large tech firms. We believe commitments from leading technology firms to move core business into the state will only continue to drive increasing demand for natural gas. I have spent a significant portion of my career working Gulf Coast and Deep Tuscaloosa assets, and I believe Expion has established a compelling initial position at an attractive entry point. I look forward to working with Kevin, the Board and the team to build an oil and gas program that is technically rigorous and capital-disciplined.”
