PIEDMONT LITHIUM ANNOUNCES ADJOURNMENT OF 2025 SPECIAL MEETING OF STOCKHOLDERS UNTIL AUGUST 22, 2025

Belmont, North Carolina, August 11, 2025 – Piedmont Lithium Inc. (“Piedmont,” the “Company”) (Nasdaq: PLL; ASX: PLL), a leading North American supplier of lithium products critical to the U.S. electric vehicle supply chain, today announced that after convening the Company’s 2025 Special Meeting of Stockholders (the “Special Meeting”) virtually on Monday, August 11, 2025 at 11 a.m. Eastern Time, the Company adjourned the Special meeting until Friday, August 22, 2025 at 11 a.m. Eastern Time. Piedmont Lithium will be holding its adjourned Special Meeting in virtual-only format, by way of webcast, and no physical or in-person meeting will be held.

“With 47.05% of the shares outstanding and 97.77% of the votes case in favor of the proposed merger with Sayona, we’ve seen meaningful progress and continued strong support for the proposal over the last week,” said Keith Phillips, President and CEO of Piedmont Lithium. “However, the fact remains that we have not received votes from the majority of the shares outstanding needed to approve the transaction. This merger cannot move forward without shareholder approval, and we urge every shareholder that has not yet voted to do so as soon as possible.”

VOTING INSTRUCTIONS FOR COMMON STOCKHOLDERS:

VOTING INSTRUCTIONS FOR CHESS DEPOSITARY INTERESTS (“CDIs”) HOLDERS:

At the time of the Special Meeting on August 11, a total of 10,645,325 shares of the Company’s common stock, or 48.50% of the common stock outstanding and entitled to vote as of June 16, 2025 (including shares of common stock underlying CDIs), the record date for the Special Meeting (the “Record Date”), were present at the Special Meeting, either virtually or represented by proxy, which fell short of the majority of shares of common stock outstanding and entitled to vote required to reach quorum. For the sole reason of the lack of quorum, the Company adjourned the Special Meeting to provide the Company’s stockholders additional time to vote their shares.

The preliminary voting tabulation, as of the time of the August 11 Special Meeting, is set forth below. As a reminder, the polls remain open and we encourage all stockholders to vote their shares if they have not already done so. Details of the final voting results, including votes validly received at the adjourned Special Meeting, will be tabulated and included with the official minutes of the Special Meeting and will be available for all stockholders in our filings with the U.S. Securities and Exchange Commission within four business days.

We encourage all stockholders to actively take steps to vote their shares. See below under “How do I vote” for instructions on how to vote if you have not already voted.

The record date for determining stockholders and CDI holders eligible to vote at the Special Meeting will remain the close of business on June 16, 2025. Stockholders and CDI holders who have already submitted a valid proxy or in the case of CDI holders, a CDI voting instruction form, do not need to vote again for the adjourned Special Meeting, as the proxies and CDI voting instructions submitted will remain valid.
