Montauk Renewables Celebrates Opening of Turkey, NC facility in Sampson County

The Project Represents $200 Million Agribusiness Investment


Turkey, NC – September 16, 2026 — Montauk Renewables Inc. (NASDAQ: MNTK) (“Montauk”
or the “Company”) and its subsidiary, Montauk Renewables Ag, LLC, announce that Sampson
County leaders joined Montauk’s Chief Executive Officer, Sean McClain, and members of its
Board of Directors to celebrate the official opening of the Company’s Turkey, NC facility. The
project represents a $200 million capital investment and commitment to rural North Carolina.

"As of the end of August, we have entered into long-term agreements with over 80 separate
farming locations, providing us access to more than 415,000 of the hog spaces we are
targeting for our first phase of development. Farmers are the backbone of the North Carolina
economy, and we are thankful to partner with them and Sampson County,” stated Sean
McClain, Montauk Renewables CEO.

State and local officials worked with the Company to transform the former Bay Valley Foods
Distribution Center into a major investment providing excellent jobs and expanding the tax
base in Sampson County. The Company has developed technology that allows them to
transform swine waste into electricity.

Senator Brent Jackson, a Sampson County farmer and leader on agricultural issues in the
General Assembly, offered, “I am grateful that agriculture and agribusiness continue to invest
and grow in North Carolina. Montauk’s capital investment is great news for Sampson County.
This is not only good news for the pork producers, but the biochar produced here will also
improve nutrient and water retention, supporting healthier soil and stronger crop yields.”

Senator Jackson serves as Chairman of the Appropriations Base Budget Committee and
Chairman of the Agriculture, Energy and Environment Committee in the NC Senate.

Agriculture has an annual economic impact of more than $100 billion for the North Carolina
economy, according to the N.C. Department of Agriculture. It is the state’s top industry,
supporting roughly one in five jobs and spanning more than 42,000 farms across 8 million
acres.
