04/22/2026
Japan-based electronics manufacturer JST Corp. plans to expand its operations in Guntersville, Alabama. The $500 million project is expected to create 80 jobs in Marshall County.

The investment will include the construction of a 540,000-square-foot manufacturing and design facility, located at Conners Island Business Park, featuring advanced automation technologies across injection molding, stamping, plating, and assembly operations.

“We are excited to expand on our success in Guntersville,” said Phillip Mosley, Sales Manager for JST. “This facility will showcase our advanced automation capabilities while leveraging Alabama’s strong manufacturing environment.”

JST Corporation is a manufacturer of electrical connectors and interconnection systems used in electronics and industrial equipment. The company produces wire-to-board, wire-to-wire, and terminal products for automotive, consumer electronics, and industrial applications.

“Innovative companies like JST are the backbone of our advanced manufacturing sector,” noted Ellen McNair, Secretary of the Alabama Department of Commerce. “This expansion reflects the strength of our workforce and business environment.”

“As chair of the Guntersville Industrial Development Board, I’m deeply grateful for the sustained investments and leadership from our state and local officials, and the partnership we share with Mayor (Leigh) Dollar and her team, local utilities, TVA, Snead State, the Alabama Department of Commerce, the governor’s office, and our legislative delegation,” added Zach Lee, chair of the Guntersville Industrial Development Board. “All these were critical not only to building the Conners Island park but also to the community and workforce development needed to attract industry and create good jobs.
