VCHARGE± Manufacturing Strategy Developed

During Q1 2021, the Company finalized the manufacturing strategy for its clean energy division and began to establish the supply chain required to deliver on its targeted deployment timelines and cost structure. In April 2021, the Company secured a location for its stack manufacturing and product development center in Massachusetts, U.S. with an expected nameplate manufacturing capacity of 1.4 GWh per year. This facility will be the global headquarters of Company's clean energy division. The Company also approved a location in New Hampshire, U.S. for its clean energy division's electrolyte production and manufacturing of containerized VRFB systems.

Paulo Misk, President and CEO of Largo, stated: "We continued to make considerable progress in advancing our clean energy division with the view of becoming a leading player in the long-duration energy storage sector with our superior VRFB technology. I am pleased to report that the Company secured its U.S. based stack manufacturing facility and product development center, which is expected to have an annual manufacturing capacity of 1.4 GWh."

He continued: "Supported by robust sector demand and global carbon reduction targets, we continue to view the strategic growth opportunity associated with our clean energy division as a strong source of value creation for the Company. We are planning Largo's Battery Day to highlight our development strategy, showcase the VCHARGE± system technological differentiations and detail the Company's sizable growth opportunity in the long-duration energy sector as we position ourselves toward a sustainable future. We will provide a date for this event soon."

The Company is progressing with the certification of its VCHARGE± system under UL1973 and UL9540 requirements and expects to conclude this process shortly. Hiring of additional personnel to support the Company's anticipated targets continues.

He has extensive experience in the successful development and execution of gas and renewable projects, holding leadership positions for both major U.S. utilities and energy technology providers.
