other uncertainties and risk factors set out in filings made from time to time with the U.S. Securities and Exchange Commission (“SEC”) and the Australian Securities Exchange, including Piedmont’s most recent filings with the SEC. The
forward-looking statements, projections and estimates are given only as of the date of this presentation and actual events, results, performance and achievements could vary significantly from the forward-looking statements, projections and
estimates presented in this presentation. Readers are cautioned not to put undue reliance on forward-looking statements. Piedmont disclaims any intent or obligation to update publicly such forward-looking statements, projections and
estimates, whether as a result of new information, future events or otherwise. Additionally, Piedmont, except as required by applicable law, undertakes no obligation to comment on analyses, expectations or statements made by third parties in
respect of Piedmont, its financial or operating results or its securities. Qualified Persons Statement We have reported mineral reserves, which were prepared in accordance with Regulation S-K Item 1300 (as promulgated by the SEC, “S-K
1300”) and the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the “JORC Code”) (as required by the ASX), in connection with our exploration and evaluation activities. As of
December 31, 2022, we reported 18.3 million metric tons of probable mineral reserves at a grade of 1.10% Li2O. We issued our first mineral resource estimate pursuant to S-K 1300 and the JORC Code on October 21, 2021 and have not finalized any
subsequent estimates. The proven and probable reserve figures presented herein are estimates based on information available at the time of calculation. The mineral resource figures presented herein are estimates based on information
available at the time of calculation and do not include that portion of our mineral resources that been converted to proven and probable reserves as shown above, as they are reported exclusive of mineral reserves. We have reported mineral
resources, prepared in accordance with S-K 1300, as part of our exploration and evaluation activities. As of December 31, 2022, we have reported 25.89 million metric tons of mineral resources, exclusive of mineral reserves, at a grade of
1.06% Li2O. An initial Technical Report Summary with respect to our estimated mineral reserves was filed as an exhibit to our Transition Report for the six-month period ending December 31, 2021. An Amended Technical Report Summary, dated
April 20, 2023 (the “Amended TRS”), was filed as Exhibit 96.3 to our most recent Form 10-K/A to include certain information as required by S-K 1300. Key assumptions and parameters relating to our estimates of mineral reserves and resources
are discussed in Sections 1.9 and 1.10 of the Amended TRS. We intend to publish reserves annually and recalculate reserves if any new significant changes are expected, taking into account metal prices, changes to estimates of future
production and costs, divestments and depletion, as well as any acquisitions and additions. As required by ASX Listing Rules, Piedmont confirms that: a) it is not aware of any new information or data that materially affects the information
included in our most recent form 10-K/A ; b) all material assumptions and technical parameters underpinning mineral reserves, mineral resources, production targets, and related forecast financial information derived from production targets
included in our form 10-K/A continue to apply and have not materially changed; and c) the form and context in which the relevant Qualified Persons’ findings are presented in this report have not been materially modified from the Amended
TRS. Disclaimers
Disclaimers Cautionary Note to United States Investors Concerning Estimates of
Measured, Indicated and Inferred Mineral Resources Standards for Assessing Mineral Reserves and Resources As a U.S. public company listed in the United States and Australia, Piedmont is required to comply with the resource estimation
standards of both S-K 1300 and the JORC Code. Certain of Piedmont’s partners instead comply with the JORC Code or Canadian National Instrument 43-101, Standards of Disclosure for Mineral Projects (“NI 43-101”). Each of these standards
contain specific meanings for terms such as "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" “proven mineral reserves,” “probable mineral reserves” and for various types of
technical studies. Although the principles for reporting mineral reserves and resources, including subcategories of measured, indicated and inferred resources, are broadly similar under each set of standards, we caution you that estimates
prepared solely under the JORC Code or NI 43-101 are not fully comparable to similarly titled measures disclosed under S-K 1300 or the other reporting and disclosure requirements of the U.S. federal securities laws, rules and
regulations. Mineral Reserves and Resources of Piedmont Mineral reserve and mineral resource information contained in this presentation for the Carolina Lithium Project was prepared by Piedmont in accordance with S-K 1300 and the JORC
Code. Mineral Reserves and Resources of Sayona Quebec Mineral reserve and mineral resource information contained in this presentation for the Authier and North American Lithium Projects was prepared by Sayona in accordance with the JORC
Code and NI 43-101. Such information was not prepared in accordance with S-K 1300. Mineral Reserves and Resources of Atlantic Lithium Mineral reserve and mineral resource information contained in this presentation for the Ewoyaa Project was
prepared by Atlantic Lithium in accordance with the JORC Code. Such information was not prepared in accordance with S-K 1300. In June 2023, Atlantic Lithium announced the successful completion of a technical study for Ewoyaa in accordance
with the JORC Code, demonstrating the potential of Ewoyaa to produce low-cost spodumene concentrate using a dense medium only processing technique. In the Atlantic Lithium study, 6% of the mined tons reported in the production target was
based on the inclusion of inferred resources. There is a low level of geological confidence associated with inferred mineral resources, and there is no certainty that further exploration work would result in a determination of measured or
indicated mineral resources resulting from the inferred resources, that the inferred resources would be converted to mineral reserves or that the production target itself would be realized. Although Atlantic Lithium has characterized this
technical study as a definitive feasibility study, due to the inclusion of the inferred resources, we consider the production target and its associated economics as a scoping study.

Market Outlook 6 Demand growth remains strong; low prices increase risk to
future supply February 2024 Exploring options to optimize production between Whabouchi and James Bay, which “likely delays first spodumene volumes by 6 to 9 months” Reducing pace and amount of spend in Argentina, which “likely delays first
expansion volumes by 6 to 9 months” Mt. Cattlin volumes expected to be lower year-over-year in 2024 as “a result of a reduced mining and production plan in light of current low-price environment” February 2024 “At Richburg, that’s not a
canceled project, it’s been delayed. We hope to work out a solution, but it requires better pricing in order to execute.” February 2024 “We’re not really in a hurry to turn (Wodgina Train 3) on. We’re just going to pack up and move, sit and
have a look and see where the price goes...when the price is okay, we’ll bring that stream on.” January 2024 “FY24 production guidance has been revised to between 1.3Mtpa to 1.4Mtpa (previously 1.4Mtpa - 1.5Mtpa) of SC6.0 spodumene
concentrate.” - IGO January 2024 “The Company has commenced a review of the planned expansion and associated ramp-up of Kathleen Valley to preserve capital and reduce the near-term funding requirements of the project.” January 2024 “Core
