Piedmont Lithium Inc. ("Piedmont," the "Company," "we," "our," or "us") (NASDAQ:PLL, ASX: PLL)), a leading North American supplier of lithium products critical to the U.S. electric vehicle supply chain, today reported its second quarter 2025 financial results.

Piedmont shipped approximately 20,200 dry metric tons ("dmt") of spodumene concentrate (~5.3% Li₂O) and recognized $11.9 million in revenue in Q2'25. The Company's realized price per dmt was $587 in Q2'25. Piedmont expects to ship approximately 113,000 to 125,000 dmt of spodumene concentrate in 2025¹. Planned production at North American Lithium ("NAL") supports the Company's 2025 shipment guidance.

NAL achieved a new quarterly production record of 58,533 dmt of spodumene concentrate in Q2'25, with lithium recovery averaging 73% and mill utilization of 93% – both representing new performance records since the restart of operations in 2023. Unit operating costs improved to A$1,232 (US$791) per dmt sold, declining 10% quarter-over-quarter with the increase in production and operating efficiencies.²

At our joint venture Ewoyaa Lithium Project ("Ewoyaa"), revised terms of the Mining Lease are being negotiated by Ghana's Cabinet ahead of being presented for review by Parliament. Development of the project remains subject to the outcome of the mining lease ratification, additional regulatory approvals, prevailing market conditions, and project financing.

As of June 30, 2025, Piedmont reported cash and cash equivalents of $56.1 million. The Company remains focused on disciplined capital allocation in response to current lithium market conditions. At the Carolina Lithium Project, Piedmont adjusted near-term land acquisitions to conserve capital while continuing to advance critical permits, including the project's air permit application and North Carolina General Stormwater permit.

With respect to the proposed merger with Sayona Mining, Piedmont adjourned its Special Meeting of Stockholders (the "Special Meeting") to August 11, 2025 in order to provide shareholders additional time to vote on the transaction.

"NAL continued to demonstrate strong operational performance in the second quarter amidst a challenging lithium market," said Keith Phillips, President and CEO of Piedmont Lithium. "NAL achieved record lithium recovery and mill utilization rates, resulting in record quarterly production and sales, which include over 20,000 tons delivered to and sold by Piedmont. As we approach our Special Meeting on August 11, we encourage all shareholders to vote on the proposed merger with Sayona Mining, which we believe is a strategic step toward enhancing long-term value."

Proposed Merger of Piedmont Lithium and Sayona Mining

Piedmont Lithium and Sayona signed a definitive merger agreement on November 19, 2024 to combine the two companies (the "Merger") to create a leading North American lithium business.

Piedmont convened a Special Meeting of Stockholders (the "Special Meeting") on Thursday, July 31, 2025 for shareholders to vote on the Merger. At the time of the Special Meeting, a total of 41.52% of the common stock outstanding and entitled to vote were present at the Special Meeting which fell short of the requirement for a majority of shares of common stock outstanding and entitled to vote to reach a quorum and approve the Merger. At the time of the Special Meeting, 97.86% of the votes cast were in favor of the Merger.

The Company adjourned the Special Meeting until Monday, August 11, 2025 to provide additional time for shareholders to participate in the vote. Piedmont remains committed to pursuing the Merger and strongly encourages all shareholders to vote.

Sayona also held an Extraordinary General Meeting (the "Sayona EGM") for Sayona shareholders to vote on the Merger on July 30, 2025. Sayona shareholders voted to approve the Merger at the Sayona EGM with 97.34% of votes cast in favor.

Second Quarter and Recent Business Highlights

Piedmont Lithium

• Shipped approximately 20,200 dmt (~5.3% Li₂O) of spodumene concentrate from NAL to customers in Q2'25 and recognized $11.9 million in revenue with an average realized sales price of $587 per dmt. On an SC6 equivalent basis, our realized price per metric ton was $668.
  
  
• Piedmont remains committed to pursuing the proposed merger with Sayona Mining and adjourned the Special Meeting on July 31, 2025 to August 11, 2025 to allow stockholders additional time to vote their shares. At the original time of the meeting, 97.86% of the votes cast were in favor of the transaction with 41.52% of the common stock outstanding and entitled to vote represented. For the merger proposal to pass, Piedmont requires a quorum of more than 50% of the shares of common stock outstanding to vote in favor.
  
  
• In April 2025, Piedmont announced key regulatory approvals for the merger were received in the United States and Canada.
  
  
• In April 2025, Piedmont announced the signing of a revised merger agreement with Sayona which incorporated, among other things, an updated exchange ratio to incorporate the terms of a proposed reverse stock split to be undertaken by Sayona as part of the merger, subject to Sayona shareholder approval.

North American Lithium (Quebec, Canada)

• In Q2'25, NAL achieved quarterly production of 58,533 dmt and shipped approximately 67,000 dmt, with approximately 20,200 dmt sold to Piedmont.
• Production increased approximately 35% compared to the prior quarter and saw the benefit from new quarterly records for lithium recoveries (73%) and mill utilization (93%).
  
  
• In April 2025, the final results from the 2024 NAL drilling program were released. The results reinforce the potential for a future expansion at NAL and will be incorporated into an updated Mineral Resource Estimate, which is expected to be released in the coming weeks.
  
  
• Concentrate shipped by Piedmont and produced and shipped by NAL:

Ewoyaa Lithium Project (Ghana)

• In June 2025, our joint venture partner Atlantic Lithium announced changes to its corporate leadership team and other initiatives focused on cost-cutting. As part of the initiatives, day-to-day management of Atlantic Lithium was consolidated under Chief Executive Officer Keith Mueller.
  
  
• In July 2025, Atlantic Lithium provided an update related to ongoing negotiations related to the Mining Lease for the Ewoyaa Lithium Project. The update noted that Ghana's Minister of Lands and Natural Resources confirmed that revised terms of the Mining Lease were being negotiated in light of the lithium price environment.

Carolina Lithium (North Carolina)

• Piedmont continues to pursue an air permit application currently under review by North Carolina's Division of Air Quality, which would allow for up to 60,000 tons per year of lithium hydroxide production at Carolina Lithium, and a North Carolina General Stormwater permit.

2025 Outlook

Under our offtake agreement with Sayona Quebec, Piedmont has the right to purchase the greater of 50% of production or 113,000 dmt per year. Based on the production projection, customer requirements, and per the Company's offtake agreement, Piedmont currently expects to ship 23,000 to 27,000 dmt in Q3'25 and approximately 113,000 to 125,000 dmt in full-year 2025. Piedmont and Sayona Mining are continuing to explore commingling shipments to achieve material transport cost savings and improve profitability.

We expect to spend less than $1 million in capital expenditures in Q3'25, the majority of which relate to permitting efforts at Carolina Lithium. Investments in and advances to affiliates reflect cash contributions to Sayona Quebec and advances to Atlantic Lithium for the Ewoyaa Lithium project. Against the backdrop of a challenging lithium price environment, we increased our outlook for full year cash contributions but continue to maintain operational discipline at NAL and progress approvals at Ewoyaa. Despite the increased outlook, we expect payments to affiliates to substantially reduce in 2025 compared to 2024. Our outlook for forecasted capital expenditures and investments in and advances to affiliates is subject to market conditions.

Safety and Sustainability

The Company continued policy development and training to support the long-term objective of establishing a robust safety and health management system. Employee engagement in safety events remained strong and identification and reporting of hazards, unsafe acts, conditions, and safety observations, and near misses continued to improve.
