Item 8.01

Other Events.

Piedmont Lithium Inc. (the “Company”) announced on August 11, 2025 that its special meeting of stockholders to approve the proposed merger with Sayona Mining Ltd (“Sayona”) has been adjourned to Friday, August 22, 2025, at 11 a.m. Eastern Time. As previously disclosed by the Company and Sayona, on November 19, 2024, Sayona and Resource Capital Fund VIII L.P. (“RCF”) signed a subscription agreement (the “RCF Subscription Agreement”) pursuant to which RCF agreed to subscribe for 2,156,250,000 Sayona ordinary shares (the “Initial Subscription Amount”) at an issue price of AU$0.032 per Sayona ordinary share, subject to certain conditions including closing of the merger. As a result of the adjournment, Sayona and RCF agreed on August 12, 2025 (Australia time) to extend the end date of the RCF Subscription Agreement from August 19, 2025 to December 31, 2025.

Under the revised terms, in addition to the Initial Subscription Amount, RCF also agreed to subscribe for options for the issuance of up to 1.2 billion shares of Sayona (the “Options”), to be issued in two tranches. Issuance of the Options to RCF is subject to certain conditions, including closing of the merger. The first tranche of Options will bring RCF’s interest to 9.99% of Sayona’s issued capital, while the second tranche, subject to regulatory approval, will cover the balance of the Options. The exercise price for each Option is set at AU$0.032, representing a 14% premium to Sayona’s closing price on August 11, 2025 (Australia time). The Options will expire at 5:00 p.m. Brisbane time on December 31, 2028, and may be exercised in parcels of no less than 200 million Options. If all the Options are exercised, Sayona would receive approximately AU$38 million in capital.
