      <div>
        <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On January 8, 2024, Alcoa Corporation (the &#8220;Company&#8221;) approved the full curtailment of the Kwinana alumina refinery (the &#8220;Refinery&#8221;) located in Western
          Australia beginning in the second quarter of 2024. The Refinery has an annual nameplate capacity of 2.2 million metric tons and has been operating at approximately 80 percent of its nameplate capacity since January of 2023. The Company&#8217;s decision
          to fully curtail the Refinery was made based on a variety of factors, including the Refinery&#8217;s age, scale, operating costs and current bauxite grades, in addition to current market conditions.&#160;</div>

      </div>

      <div><br />
      </div>

      <div>
        <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In the first quarter of 2024, Alcoa will record restructuring charges between $180 million and $200 million related to the curtailment of the Refinery.
          Alcoa&#8217;s share (after-tax and noncontrolling interest) will be between $76 million and $84 million, or $0.42 to $0.47 per share. The charges include approximately $81 million for water management costs, $55 million for employee related costs, $26
          million for asset retirement obligations, and $18 million of other costs. Alcoa&#8217;s share of related cash outlays of approximately $115 million (which includes existing employee related liabilities and asset retirement obligations) is expected to
          be spent in 2024 ($80 million) and 2025 ($35 million).</div>

      </div>

      <div><br />
      </div>

      <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">The Refinery is an asset owned by the Alcoa World Alumina and Chemicals (AWAC) joint venture among Alcoa and Alumina Limited, in which Alcoa holds a
        sixty percent ownership interest and Alumina Limited holds a forty percent ownership interest.</div>

      <div>
        <div><br />
        </div>

        <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">The Refinery currently has approximately 800 employees and this number will be reduced to approximately 250 in the third quarter of 2024, when alumina
          production will cease. Certain processes will continue until about the third quarter of 2025, when the employee number will be further reduced to approximately 50.</div>

      </div>

      <div>
        <div>&#160;</div>

        <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Beginning in the third quarter of 2024, the curtailment is expected to result in annual net income improvement of approximately
          $70&#160;million&#160;(pre-tax&#160;and noncontrolling interest), when compared to the Refinery&#8217;s net loss (pre-tax and noncontrolling interest) of approximately $130 million in 2023. The Refinery will continue to incur approximately $40 million of non-cash
          depreciation, depletion and amortization expenses annually while curtailed.</div>

          <p>PITTSBURGH--(BUSINESS WIRE)--January 8, 2024--Alcoa Corporation (NYSE: AA) today announced it plans to fully curtail production in 2024 at its Kwinana Alumina Refinery in Western Australia, with the process beginning in the second quarter. </p>
          <p> The Kwinana refinery has an annual nameplate production capacity of 2.2 million metric tons. The refinery has been operating at approximately 80 percent of its nameplate capacity since January of 2023. </p>
          <p> Matt Reed, Alcoa&#8217;s Executive Vice President and Chief Operations Officer, said the determination to curtail the 60-year-old facility is based on a variety of factors, including its age, scale, operating costs and current bauxite grades, in
            addition to current market conditions. </p>
          <p> &#8220;Today&#8217;s curtailment decision comes only after thorough and careful deliberation, and we acknowledge that this action will impact workers, business partners, and the community,&#8221; Reed said. </p>
          <p> &#8220;We deeply appreciate the commitment and support of our many loyal employees, contractors, and suppliers at our Kwinana refinery, which has made a major contribution to Western Australia&#8217;s economic development over the last 60 years of
            continual operation.&#8221; </p>
          <p> The curtailment will include a phased reduction of the workforce from around 800 employees at the start of 2024 to approximately 250 in the third quarter of this year, when all alumina production will cease. Certain processes, however, will
            continue until about the third quarter of 2025, when employee numbers will be further reduced to approximately 50. </p>
          <p> &#8220;We will work closely with our employees to provide support with transitioning to other opportunities,&#8221; Reed said. &#8220;This includes potential redeployment within our business or assistance to facilitate employment at other workplaces.&#8221; </p>
          <p> The refinery and associated residue storage facilities will continue to be actively managed. Alcoa&#8217;s port facilities located alongside the refinery will continue to operate to import raw materials and export alumina produced at the Company&#8217;s
            Pinjarra Alumina Refinery. Production at the Pinjarra and Wagerup refineries is not expected to be impacted by the curtailment at Kwinana. </p>
          <p> &#8220;We remain committed to WA in the long-term and will continue to assess options for the refinery, monitoring the factors that have led to the curtailment decision,&#8221; Reed said. </p>
          <p> The Kwinana refinery recorded a net loss (pre-tax and noncontrolling interest) of approximately $130 million in 2023. The Company expects annual improvements of approximately $70 million beginning in the third quarter of 2024 as a result of
            the curtailment. The refinery will continue to incur approximately $40 million of non-cash depreciation, depletion and amortization expenses while curtailed. </p>
          <p> In the first quarter of 2024, Alcoa will record restructuring charges between $180 million and $200 million, related to the curtailment of the refinery. Alcoa&#8217;s share (after-tax and noncontrolling interest) will be between $76 million and $84
            million, or $0.42 to $0.47 per share. The charges include approximately $81 million for water management costs, $55 million for employee related costs, $26 million for asset retirement obligations, and $18 million of other costs. Alcoa&#8217;s share
            of related cash outlays of approximately $115 million (which includes existing employee related liabilities and asset retirement obligations) is expected to be spent in 2024 ($80 million) and 2025 ($35 million). </p>

            from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Such risks and uncertainties include, but are not limited to: (a) cyclicality of the aluminum industry and aluminum end use markets, including
            due to the influence of global economic conditions, and unfavorable changes in the markets served by Alcoa; (b) the effects of non-market forces, such as government policies and political instability, on global aluminum supply and demand; (c)
            volatility and declines in aluminum industry, including global supply and demand conditions and fluctuations in London Metal Exchange-based prices and premiums, as applicable, for primary aluminum and other commodities, and fluctuations in
            indexed-based and spot prices for alumina; (d) legal, regulatory, economic, political, trade, public health and safety, and reputational risks and conditions, including changes in conditions beyond our control as a result of our participation
            in increasingly competitive and complex global markets; (e) our ability to obtain, maintain, or renew permits or approvals necessary for our mining operations; (f) unfavorable changes in cost, quality, or availability of key inputs, including
            energy and raw materials, or uncertainty of or disruption to the supply chain including logistics; (g) our ability to realize expected benefits or achieve intended results, including as planned and by targeted completion dates, from announced
            strategies, plans, programs, or initiatives relating to our portfolio, profitability, capital investments, and developing technologies, and from joint ventures or other strategic alliances or business transactions; (h) fluctuations in foreign
            currency exchange and tax rates on costs and results; (i) changes in tax laws or exposure to additional tax liabilities; (j) changes in global economic and financial market conditions generally, such as inflation, recessionary conditions, and
            interest rate increases, which may also affect Alcoa&#8217;s ability to obtain credit or financing upon acceptable terms or at all; (k) current and potential future impacts to the global economy and our industry, business and financial condition
            caused by various worldwide or macroeconomic events, such as the ongoing conflict between Russia and Ukraine; (l) global competition within and beyond the aluminum industry; (m) our ability to obtain or maintain adequate insurance coverage; (n)
            the outcomes of contingencies, including legal and tax proceedings, government or regulatory investigations, and environmental remediation, or changes in foreign and/or U.S. federal, state, or local laws, regulations, or policies; (o) the
            impacts of climate change, related legislation or regulations, and efforts to reduce greenhouse gas emissions and our ability to achieve strategies and expectations related to climate change and other environmental matters; (p) claims, costs
            and liabilities resulting from the impact of our operations, including impoundments, or from health, safety, and environmental laws, regulations, and requirements, in the areas where we operate; (q) the impact of cyberattacks and potential
            information technology or data security breaches, including disruptions to our operations, liability, and reputational harm; (r) our ability to fund capital expenditures; (s) risks associated with long-term debt obligations including
