J-Star
Holding Signs MOU with White Group to Advance Financing for Texas Solid-State Battery Facility
White
Group to support capital formation for J-Star’s Baytown, Texas automated battery manufacturing project
Taichung
City, Taiwan – May 8, 2026 — J-Star Holding Co., Ltd. (Nasdaq: YMAT) (“J-Star” or the “Company”), today
announced that it has signed a non-binding memorandum of understanding (“MOU”) with White Group Ptd., Ltd. (“White
Group”), a Singapore-based investment and development firm, to support capital formation for the Company’s planned automated
solid-state battery production facility in Baytown, Texas.
The
financing initiative builds upon J-Star’s previously announced strategic partnership with Patriot Green Energy Technology
Co., Ltd. (“PSSB”) to develop Made-in-USA polymer-based solid-state battery solutions and establish a 100 megawatt-hour (MWh)
modular production line targeting the rapidly growing unmanned aerial vehicle (UAV) and drone markets.
Under
the MOU, White Group will work with J-Star to identify and introduce potential U.S.-based private equity partners to participate in a
proposed $100 million investment to support construction, automation and technical development of the Baytown facility. The investment
is expected to complement J-Star and PSSB’s previously submitted U.S. Department of Energy grant application for the project.
Advancing
the Baytown Solid-State Battery Initiative
The
proposed capital raise represents the next phase of J-Star’s Baytown project, which already includes:
| ● | A
strategic partnership with PSSB, a developer of next-generation solid-state battery technology
backed by Taiwan’s Industrial Technology Research Institute (ITRI) |
| ● | A
jointly submitted U.S. Department of Energy grant application |
| ● | A
commitment from the Baytown Economic Development Foundation securing a site in the TGS Cedar
Port Industrial Park |
| ● | Plans
to establish a fully automated U.S. production line designed to supply high-density batteries
for aerospace, defense and dual-use drone applications |
Proceeds
from the expected financing are expected to support:
| ● | Completion
of the 100 MWh automated solid-state battery production line targeting drone and advanced
mobility applications |
| ● | Procurement
of customized automated manufacturing systems |
| ● | Technology
transfer, workforce training and infrastructure development |
| ● | Technical
milestones required for federal funding and customer qualification |
Jonathan
Chiang, CEO and Chairman of J-Star Holding, commented, “This agreement with White Group represents an important step in advancing
the financing strategy for our Baytown, Texas facility. Following our partnership with PSSB, our Department of Energy grant application,
and the securing of our Baytown site, we are now focused on building the capital structure required to bring this project into execution.
We believe the combination of Taiwanese battery innovation and U.S. manufacturing will help establish a secure domestic supply chain
for next-generation energy storage solutions serving the rapidly expanding aerospace and defense drone markets.”
