Item 1.01 Entry into a Material Definitive Agreement.

On March 11, 2024 (Eastern Daylight Time) / March 12, 2024 (Australian Eastern Daylight Time), Alcoa Corporation, a Delaware corporation (“Alcoa”), AAC Investments Australia 2 Pty Ltd, an Australian proprietary company limited by shares and an indirect wholly owned subsidiary of Alcoa (“Alcoa Bidder”), and Alumina Limited, an Australian public company limited by shares and listed on the Australian Securities Exchange (“Alumina”), entered into a Scheme Implementation Deed (the “Deed”), pursuant to which, subject to the satisfaction or waiver of the conditions set forth therein, Alcoa Bidder will acquire all Alumina ordinary shares on issue and outstanding (the “Alumina Shares”) pursuant to a court-approved scheme of arrangement under Part 5.1 of Australia’s Corporations Act 2001 (Cth) (“Corporations Act”) (the “Scheme” and such acquisition, the “Transaction”).

Under the Deed, at the time of implementation of the Scheme, all Alumina Shares issued and outstanding as of the Record Date (as defined in the Deed) will be transferred to Alcoa Bidder, and the holders of such Alumina Shares (“Scheme Participants”) will have the right to receive, for each such Alumina Share, 0.02854 CHESS Depositary Interests (“CDIs”), each representing an ownership interest in a share of Alcoa common stock (the “New Alcoa CDIs”) (except that, where a Scheme Participant resides in certain jurisdictions (each, an “Ineligible Foreign Shareholder”), such Ineligible Foreign Shareholder will receive the net proceeds of the sale by a sale nominee of shares of Alcoa common stock on its behalf (“Sale Nominee Alcoa Shares”) that such Ineligible Foreign Shareholder would otherwise be entitled to receive in the form of New Alcoa CDIs).

Conditions to the Transaction

The respective obligations of Alumina and Alcoa to consummate the Transaction are subject to the satisfaction or waiver (if applicable) of a number of customary conditions, including: (1) approval by Alumina’s shareholders of the Scheme in accordance with the Corporations Act; (2) approval by Alcoa’s shareholders of the issuance of shares of Alcoa common stock underlying the New Alcoa CDIs and the Sale Nominee Alcoa Shares (the “New Alcoa Shares”) in connection with the Scheme (the “Alcoa Shareholder Approval”); (3) regulatory approvals consisting of approval or non-objection by Australia’s Foreign Investment Review Board, approval or confirmation of no-action by the Australian Competition and Consumer Commission, and clearance by the Brazil Administrative Council for Economic Defense; (4) non-occurrence of certain actions of the parties between signing and closing of the Transaction; (5) approval of the Scheme by the Federal Court of Australia (sitting in Melbourne), or another court of competent jurisdiction under the Corporations Act agreed in writing by the parties (the “Court”); (6) the absence of any governmental order, injunction, decree or ruling by an Australian or United States court or regulatory authority prohibiting consummation of the Transaction; (7) issuance of an independent expert report concluding that the Scheme is in the best interests of the Scheme Participants before the Scheme Booklet is submitted to the Australian Securities & Investments Commission (“ASIC”); and (8) the New Alcoa Shares and New Alcoa CDIs issuable in the Transaction having been approved for listing on the New York Stock Exchange and Australian

Securities Exchange (“ASX”), respectively. The closing of the Transaction is expected to occur in the third quarter of calendar year 2024, subject to the satisfaction or waiver of such conditions.

Representations and Warranties; Covenants

The Deed contains customary representations and warranties given by Alcoa and Alumina. The Deed also contains pre-closing covenants as is customary for transactions of this nature, including, but not limited to, the obligation of each party to conduct its business in the ordinary and usual course and covenants by each of the parties to refrain from taking specified actions without the consent of the other party. The parties have agreed to use all reasonable endeavors to, among other things, implement the Scheme as soon as reasonably practicable. In addition, Alumina has agreed to ensure that no Alumina equity awards will be outstanding prior to the Scheme becoming effective by causing to vest, settling or cancelling outstanding Alumina equity awards.

Alcoa’s board of directors has unanimously recommended that Alcoa’s shareholders vote in favor of the Alcoa Shareholder Approval and Alumina’s independent directors, managing director and chief executive officer have recommended that Alumina’s shareholders vote in favor of the Scheme, with such recommendation in each case subject to customary exceptions. Each party has agreed to use its best endeavors to procure that its respective directors do not change, withdraw, qualify or modify such recommendation, subject to customary exceptions. In addition, the Deed provides that, during the period from the date of the Deed until the termination of the Deed in accordance with its terms, each party is subject to certain restrictions on its ability to solicit alternative acquisition proposals from third parties, to provide information to third parties and to engage in discussions with third parties regarding alternative acquisition proposals, subject to customary exceptions.

Termination and Termination Fees

The Deed contains certain customary termination rights for both parties, including, among others, if (1) the Scheme is not implemented by December 31, 2024 (the “End Date”), (2) the parties are unable to agree on a revision to the terms of the Scheme after a failure of certain conditions precedent to the Scheme or (3) the Court denies approval of the Scheme, and the parties agree not to appeal the denial or an independent counsel determines that an appeal would be futile. Each party may terminate the Deed if, among other things, (1) the other party’s board of directors has made an adverse change in recommendation or (2) the other party materially breaches a term of the Deed, subject to certain cure periods. In addition, each party may terminate the Deed if its board of directors has determined that a competing transaction constitutes a superior proposal.

Under the Deed, Alumina will be required to make a payment of $22 million to Alcoa if (1) the Deed is terminated by Alcoa (i) as a result of an adverse change in recommendation by any independent director, managing director or chief executive of Alumina (other than where the change is made due to the withdrawal of the independent expert’s recommendation in circumstances not involving a competing transaction for Alumina or at the Court’s or ASIC’s request) or (ii) on the basis of a material breach of the Deed by Alumina, (2) the Deed is terminated by Alumina upon Alumina’s board of directors’ determination that a competing transaction constitutes a superior proposal (other than where the independent expert’s report concludes that the Scheme is not in the best interests of the Scheme Participants in circumstances not involving a competing transaction) or (3) a competing transaction for Alumina is announced during the Exclusivity Period (as defined in the Deed), and such a competing transaction is completed within 12 months of such announcement.

Under the Deed, Alcoa will be required to make a payment of $50 million to Alumina if (1) any member of Alcoa’s board of directors makes an adverse change in recommendation, (2) the Deed is terminated by Alumina on the basis of a material breach of the Deed by Alcoa, (3) the Deed is terminated by Alcoa upon Alcoa’s board of directors’ determination that a competing transaction constitutes a superior proposal, (4) a competing transaction for Alcoa is announced prior to the termination of the Deed, and such a competing transaction is completed within 12 months of such announcement, or (5) Alcoa fails to issue the New Alcoa CDIs to the Scheme Participants pursuant to the terms of the Deed. In addition, Alcoa will be required to make a payment of $20 million to Alumina if the Deed is terminated by Alumina on the basis of the failure to obtain the Alcoa Shareholder Approval.

In the event the Scheme becomes effective, no termination fee will be payable by either party.

Governance

Under the Deed, two of Alumina’s directors who are Australian residents or citizens will be appointed to Alcoa’s board of directors on and from the date of the implementation of the Scheme.

Liquidity Support

Under the Deed, Alcoa has agreed to provide short-term unsecured shareholder loans to Alcoa World Alumina and Chemicals (“AWAC”), the joint venture between Alcoa and Alumina, in the event Alumina cannot contribute its share of an equity call by AWAC without exceeding a specified net debt threshold.

Additional Information

The foregoing description of the Transaction, the Scheme and the Deed does not purport to be complete and is qualified in its entirety by reference to the full text of the Deed, which is filed as Exhibit 2.1 to this Current Report on Form 8-K, and is incorporated herein by reference. A copy of the Deed has been included to provide investors with information regarding its terms and is not intended to provide any factual information about Alcoa or Alumina.

The Deed contains representations, warranties, covenants and agreements, which were made only for purposes of such agreement and as of specified dates. The representations and warranties in the Deed reflect negotiations between the parties to the Deed and are not intended as statements of fact to be relied upon by Alcoa’s or Alumina’s shareholders or any other person. In particular, the representations, warranties, covenants and agreements in the Deed may be subject to limitations agreed by the parties, including having been modified or qualified by certain confidential disclosures that were made between the parties in connection with the negotiation of the Deed, and having been made for purposes of allocating risk among the parties rather than establishing matters of fact. In addition, the parties may apply standards of materiality in a way that is different from what may be viewed as material by investors. As such, the representations and warranties in the Deed may not describe the actual state of affairs at the date they were made or at any other time and you should not rely on them as statements of fact. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Deed, and unless required by applicable law, Alcoa undertakes no obligation to update such information.

Forward-Looking Statements

This Current Report on Form 8-K contains statements that relate to future events and expectations and as such constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include those containing such words as “aims,” “ambition,” “anticipates,” “believes,” “could,” “develop,” “endeavors,” “estimates,” “expects,” “forecasts,” “goal,” “intends,” “may,” “outlook,” “potential,” “plans,” “projects,” “reach,” “seeks,” “sees,” “should,” “strive,” “targets,” “will,” “working,” “would,” or other words of similar meaning. All statements by Alcoa Corporation (“Alcoa”) that reflect expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, statements regarding the proposed transaction; the ability of the parties to complete the proposed transaction; the expected benefits of the proposed transaction, the competitive ability and position following completion of the proposed transaction; forecasts concerning global demand growth for bauxite, alumina, and aluminum, and supply/demand balances; statements, projections or forecasts of future or targeted financial results, or operating performance (including our ability to execute on strategies related to environmental, social and governance matters); statements about strategies, outlook, and business and financial prospects; and statements about capital allocation and return of capital. These statements reflect beliefs and assumptions that are based on Alcoa’s perception of historical trends, current conditions, and expected future developments, as well as other factors that management believes are appropriate in the circumstances. Forward-looking statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties, and changes in circumstances that are difficult to predict. Although Alcoa believes that the expectations reflected in any forward-looking statements are based on reasonable assumptions, it can give no assurance that these expectations will be attained and it is possible that actual results may differ materially 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: (1) the non-satisfaction or non-waiver, on a timely basis or otherwise, of one or more closing conditions to the proposed transaction; (2) the prohibition or delay of the consummation of the proposed transaction by a governmental entity; (3) the risk that the proposed transaction may not be completed in the expected time frame or at all; (4) unexpected costs, charges or expenses resulting from the proposed transaction; (5) uncertainty of the expected financial performance following completion of the proposed transaction; (6) failure to realize the anticipated benefits of the proposed transaction; (7) the occurrence of any event that could give rise to termination of the proposed transaction; (8) potential litigation in connection with the proposed transaction or other settlements or investigations that may affect the timing or occurrence of the contemplated transaction or result in significant costs of defense, indemnification and liability; (9) the impact of global economic conditions on the aluminum industry and aluminum end-use markets; (10) volatility and declines in aluminum and alumina demand and pricing, including global, regional, and product-specific prices, or significant changes in production costs which are linked to LME or other commodities; (11) the disruption of market-driven balancing of global aluminum supply and demand by non-market forces; (12) competitive and complex conditions in global markets; (13) our ability to obtain, maintain, or renew permits or approvals necessary for our mining operations; (14) rising energy costs and interruptions or uncertainty in energy supplies; (15) unfavorable changes in the cost, quality, or availability of raw materials or other key inputs, or by disruptions in the supply chain; (16) our ability to execute on our strategy to be a lower cost, competitive, and integrated aluminum production business and to realize the anticipated benefits from announced plans, programs, initiatives relating to our portfolio, capital investments, and developing technologies; (17) our ability to integrate and achieve intended results from joint ventures, other strategic alliances, and strategic business transactions; (18) economic, political, and social conditions, including the impact of trade policies and adverse industry publicity; (19) fluctuations in foreign currency exchange rates and interest rates, inflation and other economic factors in the countries in which we operate; (20) changes in tax laws or exposure to additional tax liabilities; (21) global competition within and beyond the aluminum industry; (22) our ability to obtain or maintain adequate insurance coverage; (23) disruptions in the global economy caused by ongoing regional conflicts;

(24) legal proceedings, investigations, or changes in foreign and/or U.S. federal, state, or local laws, regulations, or policies; (25) climate change, climate change legislation or regulations, and efforts to reduce emissions and build operational resilience to extreme weather conditions; (26) our ability to achieve our strategies or expectations relating to environmental, social, and governance considerations; (27) claims, costs and liabilities related to health, safety, and environmental laws, regulations, and other requirements, in the jurisdictions in which we operate; (28) liabilities resulting from impoundment structures, which could impact the environment or cause exposure to hazardous substances or other damage; (29) our ability to fund capital expenditures; (30) deterioration in our credit profile or increases in interest rates; (31) restrictions on our current and future operations due to our indebtedness; (32) our ability to continue to return capital to our stockholders through the payment of cash dividends and/or the repurchase of our common stock; (33) cyber attacks, security breaches, system failures, software or application vulnerabilities, or other cyber incidents; (34) labor market conditions, union disputes and other employee relations issues; (35) a decline in the liability discount rate or lower-than-expected investment returns on pension assets; and (36) the other risk factors discussed in Part I Item 1A of Alcoa’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and other reports filed by Alcoa with the SEC. These risks, as well as other risks associated with the proposed transaction, will be more fully discussed in the proxy statement. Alcoa cautions readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date they are made. Alcoa disclaims any obligation to update publicly any forward-looking statements, whether in response to new information, future events or otherwise, except as required by applicable law. Market projections are subject to the risks described above and other risks in the market. Neither Alcoa nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements and none of the information contained herein should be regarded as a representation that the forward-looking statements contained herein will be achieved.

If Alcoa and Alumina disagree on the form or content of the Scheme Booklet, they must consult in good faith to try to settle an agreed form or content of the Scheme Booklet. If complete agreement is not reached after 3 Business Days of reasonable consultation, then:

(a) if the disagreement relates to the form or content of the Alcoa Information or the Combined Group Information contained in the Scheme Booklet, Alumina will make any amendments as Alcoa requires (acting reasonably and in good faith), unless the information relates to Alcoa in the Independent Expert’s Report, in which case Alumina will only communicate the request for amendment to the Independent Expert; and

In order to ensure the availability of the exemption under Section 3(a)(10) of the Securities Act and to facilitate Alcoa’s compliance with other U.S. securities laws, the parties agree that:

(a) before the commencement of the hearing on the First Court Date, the Court shall be advised of the intention of Alcoa and Alumina to rely on the exemption from registration requirements provided by Section 3(a)(10) of the Securities Act with respect to the issuance of New Alcoa Shares (including in the form of New Alcoa CDIs) to Scheme Participants pursuant to the Scheme, based on the Court’s approval of the Scheme, and that its approval of the Scheme is to be relied upon as a determination that the Court has satisfied itself as to the procedural and substantive fairness of the terms and conditions of the Scheme to all persons who are entitled to receive Scheme Consideration pursuant to the Scheme;

(b) Alumina will ensure that each Alumina Shareholder entitled to receive Scheme Consideration pursuant to the Scheme will be given adequate and appropriate notice advising them of their right to attend the hearing of the Court to approve the Scheme, including the consideration of the procedural and substantive fairness of the terms and conditions of the Scheme to all persons who are entitled to receive Scheme Consideration pursuant to the Scheme and providing them with sufficient information necessary for them to exercise that right; and

ã King & Wood Mallesons Scheme Implementation Deed   44

(c) the Scheme Booklet will include a statement to substantially the effect that the New Alcoa Shares issued pursuant to the Scheme have not been registered under the Securities Act and will be issued by Alcoa in reliance on the exemption from registration under Section 3(a)(10) of the Securities Act and that certain restrictions on resale under U.S. securities laws, including Rule 144 under the Securities Act, may be applicable with respect to securities issued to holders that are (or have been in the 90 days immediately prior to the issuance of the New Alcoa Shares) affiliates (as defined in Rule 405 of the Securities Act) of Alcoa.

(c) Without limiting clause 10, if an Alcoa Board Member proposes to change, withdraw, qualify or modify their recommendation, Alcoa must notify Alumina in writing as soon as practicable.

9.6 Funding of equity calls

(a) Notwithstanding any restrictions in or imposed by the Charter of the Strategic Council, Alcoa and Alumina agree that, from the date of this document up to and including the Lending Cessation Date, any funding required to meet the needs of AWAC or the AWAC Entities will be met first, out of the cashflow of AWAC and the AWAC Entities, and secondly:

(i) by way of equity call made in accordance with Section 8(a) of the Charter of the Strategic Council, subject to clause 9.6(a)(ii) below; and

(ii) if Alumina is unable to contribute its share of the relevant equity call without its total “Loans” (as defined in the Alumina Facility Agreement) exceeding the Alumina Headroom Limit, and Alumina elects to notify Alcoa and the applicable AWAC Entity that it requires funding under this clause 9.6(a)(ii) within 14 days of the equity call, by the following mechanism:

(C) Alcoa providing, or procuring that one of its Subsidiaries (other than an AWAC Entity) provides a shareholder loan (Alcoa Shareholder Loan) to the applicable AWAC Entity for a principal amount equal to 40% (or such lesser percentage as may represent Alumina’s interest in AWAC at that time) of the Aggregate Equity Amount, plus capitalised interest, and on terms that are in accordance with and governed by the applicable Alcoa Shareholder Loan Agreement, and on the basis that there will be no dilution of Alumina’s interest in AWAC, by virtue of the Alcoa Shareholder Loan, other than in the circumstances contemplated by clause 9.6(d); and

(D) immediately following payment of some or all of the equity call to which it relates by Alumina, Alcoa procuring that the applicable AWAC Entity repays the Alcoa Shareholder Loan (in full or, if the amount of the Alumina payment of the equity call is less than the total amount outstanding under the Alcoa Shareholder Loan, in part to the extent of the Alumina payment only).

ã King & Wood Mallesons Scheme Implementation Deed   54

For the avoidance of doubt, if Alumina does not elect to notify Alcoa and the applicable AWAC Entity that it requires funding under clause 9.6(a)(ii) within the 14 day period referred to in the first paragraph of clause 9.6(a)(ii), Alumina will be obliged to contribute its share of that equity call in accordance with Section 8(a) of the Charter of the Strategic Council.

If Alumina elects to notify Alcoa and the applicable AWAC Entity that it requires funding under this clause 9.6(a)(ii) within 14 days of the equity call, then Alumina and Alcoa shall negotiate in good faith for a period ending on the last day of the 30 day notice period for that equity call to agree the form of the Alcoa Shareholder Loan Agreement. If, at the end of such negotiation period, Alcoa and Alumina have not agreed the form of the Alcoa Shareholder Loan Agreement, then Alcoa may execute a form of Alcoa Shareholder Loan Agreement, on terms consistent with the Shareholder Loan Term Sheet, with the relevant AWAC Entity.

(b) Provided that Alumina has complied with clause 9.6(a), Alumina will continue to receive distributions reflecting a 40% (or such lesser percentage as may represent Alumina’s interest in AWAC at that time) interest in AWAC and the AWAC Entities, including prior to the Funding Deadline.

(c) If an Alcoa Shareholder Loan has been advanced in accordance with clause 9.6(a)(ii)(C) and has not been repaid in full in accordance with this clause 9.6 at the relevant time of distribution:

(i) Alumina agrees that any distributions that it is entitled to from an AWAC Entity will be used to satisfy equity calls made to it by an AWAC Entity, and hereby directs that such distributions are applied accordingly; and

(ii) Alumina must not declare or pay any distributions to Alumina Shareholders or undertake any other return of capital until such time as the relevant Alcoa Shareholder Loan has been repaid in full or converted to equity in accordance with clause 9.6(d) below.

If Alumina breaches this clause 9.6(c)(ii), any outstanding equity call at the time of the breach will immediately accelerate and require payment in full of Alumina’s share of the Aggregate Equity Amount within 5 Business Days.

(d) If Alumina does not make one or more equity contributions by the Funding Deadline as required under clause 9.6(a), Alcoa may, at its election, contribute Alumina's share by effectively converting the corresponding Alcoa Shareholder Loan(s) into an equity contribution on behalf of Alumina in the manner set out in subsection (i) of Section 8(a) of the Charter of the Strategic Council, and Alumina agrees that, in this scenario, its interest in AWAC and each of the AWAC Entities will be diluted by reference to the amount of the Alcoa Shareholder Loan so converted into an equity contribution, in accordance with the formula set out in Exhibit A of the Charter of the Strategic Council.

(e) For the purposes of clause 9.6(a), Alcoa must procure that any Alcoa Shareholder Loan will be provided without being limited by reference to either:

(i) the Target Enterprise Debt Level (as defined in the Charter of the Strategic Council); or

(f) Alcoa acknowledges and agrees that it will not, and will procure that each relevant Alcoa Group Member does not:

(i) amend or vary the terms of any Alcoa Shareholder Loan Agreement; or

(ii) waive any rights under, or assign, novate or replace, any Alcoa Shareholder Loan Agreement,

or otherwise consent to any of the foregoing, without Alumina's prior written consent (such consent not to be unreasonably withheld or delayed).

(g) Subject to clause 9.6(c), if this document is terminated in accordance with clause 14.1, then Alcoa must ensure that:

(i) it does not effect or procure repayment of any Alcoa Shareholder Loan; and

(ii) there is no breach, event of default or other event or circumstance which obliges or requires repayment of any such Alcoa Shareholder Loan,

in each case during the period ending on the Funding Deadline.

(h) For the avoidance of doubt, the parties agree that:

(i) any repayment of an Alcoa Shareholder Loan in accordance with this clause 9.6 will not impact or affect in any way the continuation of other existing AWAC debt funding that has been put in place to satisfy the requirements of Section 9 of the Charter of the Strategic Council, or the parties’ ongoing obligations under Section 9 of the Charter of the Strategic Council;

(ii) there will be no dilution of Alumina’s interest in AWAC during the period up to the Funding Deadline; and

(iii) to the extent of any inconsistency between the operation of this clause 9.6 and any other AWAC Agreement, this clause 9.6 will prevail.

(i) This clause 9.6 survives the termination of this document.

Scheme Implementation Deed

Annexure A    Public announcements

(Alumina)
ASX Announcement 12 March 2024

Alumina enters into binding Scheme Implementation Deed with Alcoa

Alumina Limited (“Alumina”) announces that it has entered into a Scheme Implementation Deed (“SID”) with Alcoa Corporation (“Alcoa”) in relation to a proposal for Alcoa to acquire 100% of the fully paid ordinary shares in Alumina by way of a scheme of arrangement (“the Transaction”).

Under the terms of the SID, eligible Alumina shareholders will be entitled to receive 0.02854 shares of Alcoa common stock (in the form of ASX-listed Alcoa CHESS Depositary Interests (CDIs)) for each Alumina share held. This exchange ratio implies a 19.5% premium to the average exchange ratio over the last 12 months¹.

On implementation of the Transaction, Alumina shareholders on the record date will own approximately 31.6% of the combined group, and existing Alcoa shareholders will own approximately 68.4%.²

Alcoa has agreed to establish a foreign exempt listing on the Australian Securities Exchange (ASX), which would enable Alumina shareholders to trade shares of Alcoa common stock via CDIs on the ASX, in the same way they would normally trade ASX-listed Alumina shares.

Alcoa has agreed to appoint two existing Alumina directors who are Australian residents or citizens to the Alcoa board of directors, on implementation of the Transaction.³

Board Recommendation

The Independent Non-executive Directors and Managing Director and CEO of Alumina recommend that Alumina shareholders vote in favour of the Transaction, in the absence of a superior proposal for Alumina and subject to the independent expert concluding (and continuing to conclude) that the Transaction is in the best interests of Alumina shareholders.⁴

Additionally, the Independent Non-executive Directors of Alumina, and the Managing Director and CEO of Alumina, intend to vote all shares in Alumina which they hold or control in favour of the Transaction at the scheme meeting, in the absence of a superior proposal for Alumina and subject to the independent expert concluding (and continuing to conclude) that the Transaction is in the best interests of Alumina shareholders.

¹Based on the daily closing prices of Alumina and Alcoa and the daily prevailing AUD/USD foreign exchange rate, over the period of 12 months prior to the announcement of the proposed transaction to the ASX on 26 February 2024.

² Based on the current shares on issue of 2,901,681,417 for Alumina and 179,558,990 for Alcoa. On a fully diluted share basis, including stock options, stock units, conditional and performance rights, Alumina shareholders would own 31.25% of the merged entity.

³ The identity of the individuals will be mutually agreed by Alcoa and Alumina and their appointment is subject to customary questionnaires and background checks.

⁴ The Non-independent Non-executive Director of Alumina abstains from making a recommendation.

Benefits of combining with Alcoa

The Transaction is expected to provide a number of benefits to Alumina shareholders, including the following:

· Unifies the ownership of Alcoa World Alumina and Chemicals (“AWAC’). The Transaction represents a logical combination which simplifies the corporate structure and aligns the interests of the two AWAC joint venture partners. If the Transaction is implemented, Alumina shareholders will exchange their interest in a minority non-operating joint venture partner for a direct interest in the operating entity.

· Exposure to a leading global pure play upstream aluminium company with a geographically diversified portfolio across bauxite, alumina and aluminium. Alumina shareholders will benefit from increased exposure to aluminium, a key product for energy transition and decarbonisation, while maintaining significant exposure to AWAC.

· Enhanced capital structure. The Transaction will eliminate the capital structure inefficiencies embedded in the current joint venture structure, with AWAC’s balance sheet being largely ungeared historically. The Transaction will enable more efficient funding, resulting in potential financial synergies which will be shared by Alumina shareholders as investors in the combined group.

· Better platform for the future. The combined entity is expected to have increased financial flexibility and greater strategic optionality through access to a larger and stronger balance sheet.

Alumina Chairman, Peter Day, said: “We believe the time is right to combine our two companies. The combined entity will have a larger and stronger balance sheet, and be better able to fund the current portfolio restructuring actions in AWAC, as well as realising potential growth options in the medium to longer term. Alumina shareholders will participate in a leading global pure play upstream aluminium company, with a low carbon smelting portfolio.”

Key conditions and terms

Alumina and Alcoa have entered into the binding SID, which contains the terms on which Alumina and Alcoa agree to implement the Transaction.

In summary, key conditions for implementation of the Transaction include:

· Alumina shareholder approval in respect of the scheme of arrangement;

· Alcoa stockholder approval authorising the issuance of Alcoa shares as consideration under the scheme of arrangement;

· regulatory approvals and confirmations from Australia’s Foreign Investment Review Board, the Australian Competition and Consumer Commission, and the Brazilian Administrative Council for Economic Defense;

· approval of the Federal Court of Australia;

· the independent expert concluding (and continuing to conclude) that the Transaction is in the best interests of Alumina shareholders;

· receipt of confirmation of an ATO class ruling for scrip-for-scrip roll over relief; and

· other customary conditions.

The SID is subject to customary deal protections for both Alcoa and Alumina, including no shop, no talk, no due diligence and notification obligations. Alumina is also bound by other customary provisions, including a matching right for Alcoa in the event of a competing proposal for Alumina.

The SID includes certain circumstances in which a break fee of US$22 million would be payable to Alcoa, or a reverse break fee of up to US$50 million would be payable to Alumina.

Full details of the terms and conditions of the Transaction are set out in the SID, a copy of which is set out in Annexure A.

Indicative Timetable and Next Steps

Alumina shareholders do not need to take any action at this stage.

As outlined above, the Transaction is subject to a number of conditions, including approval of Alumina shareholders at a scheme meeting which is targeted to be held in 3Q 2024.

Alumina will send a scheme booklet containing an explanatory statement and notice of meeting to Alumina shareholders in due course. The scheme booklet will contain information in relation to the Transaction and an independent expert’s report on whether the Transaction is in the best interests of Alumina shareholders

If the Transaction is approved by Alumina shareholders and the other conditions precedent are satisfied or waived, the Scheme is expected to be implemented by 3Q 2024⁵.

Alcoa Enters into Binding Agreement to Acquire Alumina Limited

Alcoa enters into Scheme Implementation Deed with Alumina Limited on terms consistent with previously agreed and announced Process Deed

Both Alcoa and Alumina Limited Boards of Directors recommend that its shareholders vote in favor of the transaction

Expected to result in long-term value creation for both companies’ shareholders

PITTSBURGH – March 11, 2024 – Alcoa (NYSE: AA or “Alcoa”) today announced that it has entered into a binding Scheme Implementation Deed (the “Agreement”) with Alumina Limited (ASX: AWC), under which Alcoa will acquire Alumina Limited in an all-scrip, or all-stock, transaction. The Agreement terms are consistent with the previously agreed and announced transaction process deed (“Process Deed”).

Consistent with the Process Deed, the Alumina Limited Board of Directors has recommended that Alumina Limited shareholders vote in favor of the Agreement in the absence of a superior proposal and subject to an independent expert concluding (and continuing to conclude) that the transaction is in the best interests of Alumina Limited shareholders. The Independent Directors of Alumina Limited, and its Managing Director and Chief Executive Officer intend to vote all shares of Alumina Limited held or controlled by them in favor of the Agreement.

“Entering into the Scheme Implementation Deed to acquire Alumina Limited is a milestone on our path to deliver value for both Alcoa and Alumina shareholders,” said William F. Oplinger, Alcoa’s President and CEO. “This transaction provides enhanced opportunities for value creation, including strengthening Alcoa’s position as one of the world’s largest bauxite and alumina producers and providing Alumina Limited shareholders the opportunity to participate in a stronger, better-capitalized combined company with upside potential. We look forward to building on Alcoa’s success and continuing to execute our long-term strategy.”

Agreement Details

The terms of the Agreement are consistent with the Process Deed. Accordingly, under the Agreement, Alumina Limited shareholders would receive consideration of 0.02854 Alcoa shares for each Alumina Limited share (the “Agreed Ratio”). Upon completion of the transaction, Alumina Limited shareholders would own 31.25 percent, and Alcoa shareholders would own 68.75 percent of the combined company.¹

Based on Alcoa’s closing share price as of February 23, 2024, the last trading day prior to the announcement of the Process Deed, the Agreed Ratio implies a value of A$1.15 per Alumina Limited share and an equity value of approximately $2.2 billion for Alumina Limited. ²

As part of the Agreement, interests in Alcoa shares would be delivered in the form of CHESS Depositary Interests (“CDIs”) that represent a unit of beneficial ownership in a share of Alcoa common stock ³, which would allow Alumina Limited shareholders to trade Alcoa common stock via CDIs on the Australian Stock Exchange (“ASX”). In order to allow the trading of Alcoa CDIs, Alcoa will apply to establish a secondary listing on the Australian Securities Exchange. Alcoa has committed to maintain the CDI listing for at least 10 years.

¹ Based on fully diluted shares outstanding for Alcoa and Alumina Limited as of February 23, 2024.

² Based on the prevailing AUD / USD exchange rate of 0.656 as of February 23, 2024. 

³ Each Clearing House Electronic Sub-register System Depositary Interest represents a unit of beneficial ownership in a share of Alcoa common stock.

In addition, two new mutually agreed upon Australian directors from Alumina Limited’s Board would be appointed to Alcoa’s Board of Directors upon closing of the transaction.

Under the terms of the Agreement and at Alumina's request, Alcoa has agreed to provide short-term liquidity support to Alumina Limited to fund equity calls made by the AWAC joint venture if Alumina Limited’s net debt position exceeds $420 million. Based on AWAC's current 2024 cashflow forecast, Alcoa does not expect any support to be required in the 2024 calendar year. Subject to certain accelerated repayment triggers, Alumina Limited would be required to pay its equity calls (plus accrued interest) not later than September 1, 2025 in the event the transaction is not completed.

Allan Gray Australia, currently the largest substantial holder in Alumina Limited, has confirmed it continues to be supportive of the proposed transaction.

Transaction Timing & Conditions

The transaction is expected to be completed in the third quarter 2024, subject to the satisfaction of customary conditions as well as approval by both companies’ shareholders and receipt of required regulatory approvals. The required regulatory approvals include approvals from Australia’s Foreign Investment Review Board and from the antitrust regulators in Australia and Brazil. The transaction is not conditional on due diligence or financing.

Associated materials regarding the transaction will be available on the investor relations section of Alcoa’s website at www.alcoa.com as well as a transaction website at www.strongawacfuture.com.

Each Ineligible Foreign Shareholder authorises Alcoa Bidder to, and Alcoa Bidder must, subject to clauses ‎6.3 and ‎6.6:

A = (B/C) x D

Where

A is the amount to be paid to the Ineligible Foreign Shareholder;

ã King & Wood Mallesons Scheme of Arrangement   13

(f) If Alcoa or Alcoa Bidder receives professional advice that any withholding or other tax is required by law or by a Regulatory Authority to be withheld from a payment to an Ineligible Foreign Shareholder, Alcoa is entitled to withhold the relevant amount before making the payment to the Ineligible Foreign Shareholder (and payment of the reduced amount shall be taken to be full payment of the relevant amount for the purposes of this Scheme, including clause ‎‎6.4(c)). Alcoa or Alcoa Bidder must pay any amount so withheld to the relevant taxation authorities within the

ã King & Wood Mallesons Scheme of Arrangement   14

time permitted by law, and, if requested in writing by the relevant Ineligible Foreign Shareholder, provide a receipt or other appropriate evidence of such payment (or procure the provision of such receipt or other evidence) to the relevant Ineligible Foreign Shareholder.

6.6 Orders of a court or Regulatory Authority

ã King & Wood Mallesons Scheme of Arrangement   15

(ii) prevents consideration being provided to any particular Scheme Participant in accordance with this clause ‎6, or the payment or provision of such consideration is otherwise prohibited by applicable law, Alumina or Alcoa Bidder shall be entitled to (as applicable):

Alcoa Enters into Binding Agreement to Acquire Alumina Limited

Alcoa enters into Scheme Implementation Deed with Alumina Limited on terms consistent with previously agreed and announced Process Deed

Both Alcoa and Alumina Limited Boards of Directors recommend that its shareholders vote in favor of the transaction

Expected to result in long-term value creation for both companies’ shareholders

PITTSBURGH – March 11, 2024 – Alcoa (NYSE: AA or “Alcoa”) today announced that it has entered into a binding Scheme Implementation Deed (the “Agreement”) with Alumina Limited (ASX: AWC), under which Alcoa will acquire Alumina Limited in an all-scrip, or all-stock, transaction. The Agreement terms are consistent with the previously agreed and announced transaction process deed (“Process Deed”).

Consistent with the Process Deed, the Alumina Limited Board of Directors has recommended that Alumina Limited shareholders vote in favor of the Agreement in the absence of a superior proposal and subject to an independent expert concluding (and continuing to conclude) that the transaction is in the best interests of Alumina Limited shareholders. The Independent Directors of Alumina Limited, and its Managing Director and Chief Executive Officer intend to vote all shares of Alumina Limited held or controlled by them in favor of the Agreement.

“Entering into the Scheme Implementation Deed to acquire Alumina Limited is a milestone on our path to deliver value for both Alcoa and Alumina shareholders,” said William F. Oplinger, Alcoa’s President and CEO. “This transaction provides enhanced opportunities for value creation, including strengthening Alcoa’s position as one of the world’s largest bauxite and alumina producers and providing Alumina Limited shareholders the opportunity to participate in a stronger, better-capitalized combined company with upside potential. We look forward to building on Alcoa’s success and continuing to execute our long-term strategy.”

Agreement Details

The terms of the Agreement are consistent with the Process Deed. Accordingly, under the Agreement, Alumina Limited shareholders would receive consideration of 0.02854 Alcoa shares for each Alumina Limited share (the “Agreed Ratio”). Upon completion of the transaction, Alumina Limited shareholders would own 31.25 percent, and Alcoa shareholders would own 68.75 percent of the combined company.¹

Based on Alcoa’s closing share price as of February 23, 2024, the last trading day prior to the announcement of the Process Deed, the Agreed Ratio implies a value of A$1.15 per Alumina Limited share and an equity value of approximately $2.2 billion for Alumina Limited. ²

As part of the Agreement, interests in Alcoa shares would be delivered in the form of CHESS Depositary Interests (“CDIs”) that represent a unit of beneficial ownership in a share of Alcoa common stock ³, which would allow Alumina Limited shareholders to trade Alcoa common stock via CDIs on the Australian Stock Exchange (“ASX”). In order to allow the trading of Alcoa CDIs, Alcoa will apply to establish a secondary listing on the Australian Securities Exchange. Alcoa has committed to maintain the CDI listing for at least 10 years.

¹ Based on fully diluted shares outstanding for Alcoa and Alumina Limited as of February 23, 2024.

² Based on the prevailing AUD / USD exchange rate of 0.656 as of February 23, 2024. 

³ Each Clearing House Electronic Sub-register System Depositary Interest represents a unit of beneficial ownership in a share of Alcoa common stock.

In addition, two new mutually agreed upon Australian directors from Alumina Limited’s Board would be appointed to Alcoa’s Board of Directors upon closing of the transaction.

Under the terms of the Agreement and at Alumina's request, Alcoa has agreed to provide short-term liquidity support to Alumina Limited to fund equity calls made by the AWAC joint venture if Alumina Limited’s net debt position exceeds $420 million. Based on AWAC's current 2024 cashflow forecast, Alcoa does not expect any support to be required in the 2024 calendar year. Subject to certain accelerated repayment triggers, Alumina Limited would be required to pay its equity calls (plus accrued interest) not later than September 1, 2025 in the event the transaction is not completed.

Allan Gray Australia, currently the largest substantial holder in Alumina Limited, has confirmed it continues to be supportive of the proposed transaction.

Transaction Timing & Conditions

The transaction is expected to be completed in the third quarter 2024, subject to the satisfaction of customary conditions as well as approval by both companies’ shareholders and receipt of required regulatory approvals. The required regulatory approvals include approvals from Australia’s Foreign Investment Review Board and from the antitrust regulators in Australia and Brazil. The transaction is not conditional on due diligence or financing.

Transaction Website

Associated materials regarding the transaction will be available on the investor relations section of Alcoa’s website at www.alcoa.com as well as a transaction website at www.strongawacfuture.com.

Advisors

J.P. Morgan Securities LLC and UBS Investment Bank are acting as financial advisors to Alcoa, and Ashurst and Davis Polk & Wardwell LLP are acting as its legal counsel.
