Piedmont Lithium Releases Inaugural Sustainability Report

Piedmont Lithium ("Piedmont", "Company") (Nasdaq: PLL; ASX: PLL), a leading global developer of lithium resources critical to the U.S. electric vehicle ("EV") supply chain, today released its inaugural sustainability report, Progressing with Purpose. The report affirms the Company's commitment to being a responsible, respectful steward of the planet, people, and the communities where Piedmont plans to operate its wholly owned projects, Tennessee Lithium and Carolina Lithium.

Piedmont President and CEO Keith Phillips said the Company has a unique opportunity to chart its own course as it begins its environmental, social, and governance ("ESG") journey. "We are fortunate to be starting from a clean slate with the full ability to build sustainability into the foundation of our organization," Phillips said. "Our inaugural sustainability report represents an important first step in formalizing our ESG efforts as we develop our operations. We are pleased to share our plans with our stakeholders as we advance our projects in Tennessee and North Carolina and our equity interests in Quebec and Ghana."

The sustainability report reflects aspirations intended to guide the Company's ESG strategy and is centered on four key pillars: planet, people, communities, and governance. Key highlights include:

• Plans for modern technologies and practices, including the innovative Metso alkaline pressure leaching process for refining spodumene concentrate, to mitigate climate and environmental impacts.
• Responsible water use and management strategies to minimize consumption while ensuring robust treatment, monitoring, and mitigation.
• A progressive reclamation strategy for responsible land use at Carolina Lithium, with plans to reclaim land impacted by mining activities as soon as practical to restore and prepare the site for post-operational use.
• Completed biodiversity assessments to understand native species, protect habitats, and minimize impact.
• Efforts to establish a corporate culture where safety and health, and diversity, equity, and inclusion are key cornerstones for engaging the Company's workforce around future goals and objectives.
• Responsible sourcing considerations and commitments as the Company's projects advance.
• Plans for modern mining practices and state-of-the-art technologies to minimize noise and vibration impact for neighbors near Carolina Lithium.
• Investor, government, and community engagement activities to help inform and collaborate with key stakeholders as the Company develops its projects.
• Civic investments made in the communities where Piedmont plans to operate to help ensure long-term socio-economic development.
• The economic impact, job creation, and workforce development activities expected to result as the Company constructs and operates Carolina Lithium and Tennessee Lithium.
