Piedmont Lithium and Sayona Mining to Merge

Creates a leading North American lithium producer and developer

• Piedmont and Sayona to combine in all-stock merger with ownership split of approximately 50% / 50% on a fully diluted basis immediately post-merger and prior to the conditional equity raising
• Creating a leading North American hard rock lithium producer with geographically advantaged spodumene resources of global scale
• Simplified corporate structure aligns North American Lithium ("NAL") offtake economics, and removes contractual complexities
• Unified ownership of NAL unlocks the potential for a significant brownfield expansion
• Combined scale provides strategic flexibility to combine and optimize downstream strategies
• Material corporate, logistics, marketing, and procurement synergies
• Significantly strengthened balance sheet with two stage equity financing, with post-merger raise led by cornerstone subscription from Resource Capital Fund VIII L.P. ("RCF VIII"), associated with Resource Capital Funds ("RCF"), a critical minerals and mining-focused global investment firm
• MergeCo will endeavor to complete an additional equity raise for eligible retail shareholders post-closing

Piedmont Lithium Inc. ("Piedmont" or the "Company") (NASDAQ:PLL, ASX: PLL)), a leading North American supplier of lithium products critical to the U.S. electric vehicle supply chain, and Sayona Mining Limited ("Sayona") (ASX: SYA) announce the signing of a definitive agreement (the "Merger Agreement") to combine the two companies to create a leading lithium business, resulting in Sayona being the ultimate parent entity ("MergeCo") (the "Transaction").

The Transaction will result in an approximate 50% / 50% equity holding of shareholders of Piedmont and Sayona (on a fully diluted basis) in MergeCo immediately following the closing of the Transaction. Piedmont will be undertaking a proposed capital raise of ~US$27 million. Sayona is undertaking a capital raise of A$40 million (~US$27 million). Upon closing of the Transaction, Sayona will also undertake a conditional placement ("Conditional Placement") for A$69 million in MergeCo to Resource Capital Fund VIII L.P. ("RCF VIII"). The placement is subject to completion of the Transaction and requisite Sayona shareholder approval and other conditions. The equity raisings, aggregating to approximately US$99 million, plan to ensure MergeCo is well positioned to accelerate growth within its enlarged portfolio.

Completion of the Transaction is subject to shareholder approval for both companies and is expected to close in the first half of CY2025. A proxy statement containing important information about the Merger will be dispatched to Piedmont shareholders and filed with the U.S. Securities and Exchange Commission prior to a Piedmont shareholder meeting to seek approval of the Transaction. An Extraordinary General Meeting ("EGM NoM") of Sayona shareholders is expected to be held in the first half of calendar year 2025 to seek, amongst other things, approval of the Transaction.

Piedmont Lithium's President and Chief Executive Officer, Keith Phillips, said: "This merger combines two complementary businesses and will create a larger and stronger company. MergeCo will be North America's largest lithium producer and will have an attractive growth profile with three DFS-stage development projects and an exciting near-term brownfield expansion opportunity at NAL. The merger financing, corner-stoned by leading mining private equity group RCF, will enable us to weather the current industry downturn while making intelligent investments in our growth projects to be positioned for the recovery in lithium markets that we expect in the medium-term. MergeCo will be domiciled in Australia, but will maintain a listing on Nasdaq and a strong commitment to our Carolina Lithium project and our U.S. headquarters in Belmont, North Carolina."

Sayona's Chief Executive Officer and Managing Director, Lucas Dow, said: "This merger marks a transformative step for Sayona and Piedmont, creating a leading North American lithium producer with the scale and capabilities to meet the growing demand for lithium products. We believe our combined resources and expertise will enable us to deliver significant value to our shareholders and stakeholders. We are excited about the opportunities this merger presents to accelerate our growth plans and enhance our strategic flexibility."

Piedmont Lithium Board unanimously recommend the Transaction

The Merger Agreement and the Transaction have been unanimously approved by the board of directors of Piedmont ("Piedmont Board of Directors"). The Piedmont Board of Directors unanimously recommend shareholders vote in favor of the Transaction and intend to vote, or procure the voting of, any Piedmont shares held by them in favor of the Transaction, in each case subject to a superior proposal.

Strategic Rationale for the Merger

A combination between Piedmont and Sayona will create a simpler and stronger lithium business that is well-positioned to grow through cycles. The combination delivers scale, optimization and growth potential by creating the largest producer of hard rock lithium in North America.

• Creates largest hard rock lithium producer in North America with compelling growth profile
  • Currently the largest producing hard rock lithium miner in North America
  • Significant combined lithium Ore Reserve estimate totaling 70.4Mt @ 1.15% Li₂O and Mineral Resource estimate totaling 153.5Mt @ 1.15% Li₂O (Measured and Indicated) and 51.4Mt @ 1.07% Li₂O (Inferred)¹
  • Three high-quality development projects and the potential for brownfield expansion of NAL
• Economic alignment to pursue NAL brownfield expansion
  • Consolidated NAL offtake economics
  • Early, internal studies commenced, underpinned by a significant resource base
  • Low capital intensity with a lower cost base and shorter permitting process than identified greenfield projects
• Simplified corporate structure and shared benefits of synergies
  • Optimized logistics and procurement with potential to deliver lower operating costs
  • Marketing synergies expected through significantly expanded customer relationships
• Strengthened balance sheet with ability to fund and accelerate growth projects
  • Capital raising provides MergeCo with funding runway to operate
  • MergeCo go forward funding strategy is expected to focus on introducing strategic project-level partners with technical and funding capability and progressing non-dilutive sources of funding

Transaction Structure

The Transaction will be implemented by way of an Agreement and Plan of Merger between Piedmont and Sayona. A newly formed subsidiary of Sayona will merge with Piedmont Lithium which will result in Sayona Mining Limited being the ultimate parent entity of the merged group and will continue to be domiciled in Australia, with an ASX primary listing and a Nasdaq secondary listing of American depository shares ("ADSs").

Under the terms of the Transaction, existing holders of Piedmont Lithium shares of common stock will receive Sayona ADSs corresponding to 527 Sayona ordinary shares for each Piedmont share of common stock held and existing holders of Piedmont Lithium CHESS Depository Interests ("CDIs") will receive 5.27 Sayona Mining Limited ASX listed ordinary shares (instead of an ADS) for each Piedmont Lithium CDI held. The Transaction will result in an approximate 50% / 50% equity holding of shareholders of Sayona and Piedmont in MergeCo (on a fully diluted basis), prior to the Conditional Placement.

Governance and Leadership

Upon completion of the Merger, Lucas Dow will become the CEO and Managing Director of MergeCo and Keith Phillips will become a Strategic Advisor to MergeCo for a transition period.

The MergeCo Board will initially consist of 8 members, including (i) 4 directors to be appointed by Piedmont who will be deemed as independent by the Piedmont board, and one of which will be Chair of the MergeCo Board, and (ii) 4 directors to be appointed by Sayona, at least two of which will be deemed as independent by the Sayona board and one of which will be Lucas Dow, CEO of MergeCo.²

Independent directors, who are appropriately qualified individuals having regard to MergeCo's compliance requirements, will serve as the chairpersons of the Audit and Risk Committee, the Nomination Committee and the Remuneration Committee of MergeCo.

MergeCo will have a global presence with corporate headquarters in Brisbane, Australia, and offices in Belmont, North Carolina and Montreal, Quebec. Subject to shareholder approval of the Transaction, MergeCo is intended to be renamed at, or shortly after, the Transaction completion.

Equity Raising Overview

As part of the merger, the parties intend to raise equity capital aggregating to approximately US$99 million in a series of transactions.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

The information contained herein and previously reported by North American Lithium has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are Canadian mining terms defined in accordance with the requirements of NI 43-101. Comparable terms are now also defined by the U.S. Securities and Exchange Commission ("SEC") in its newly adopted Modernization of Property Disclosures for Mining Registrants as promogulated in its S-K 1300 standards. While the guidelines for reporting mineral resources, including subcategories of measured, indicated, and inferred resources, are largely similar for NI 43-101 and S-K 1300 standards, information contained herein that describes North American Lithium's mineral deposits is not fully comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder. Piedmont does not guaranty or verify the accuracy of any of the historical reporting of North American Lithium.
