NOTICE OF 2024 ANNUAL GENERAL MEETING OF SHAREHOLDERS

To the holders of ordinary shares of Ferroglobe Plc ("Ferroglobe" or the "Company"):

Notice is hereby given that Ferroglobe's Annual General Meeting of shareholders will be held on Tuesday, 18 June 2024 at 13:00 (British Summer Time), at the offices of the Company at 13 Chesterfield Street, London, W1J 5JN, United Kingdom ("U.K.").

The business of the Annual General Meeting will be to consider and, if thought fit, pass the resolutions below. All resolutions will be proposed as ordinary resolutions. Explanations of the resolutions are given in the explanatory notes on pages 3 to 8 of this Annual General Meeting notice and additional information on voting at the Annual General Meeting can be found on pages 8 to 10. All resolutions will be put to vote on a poll, where each shareholder has one vote for each share held.

Certain of the resolutions that shareholders of the Company will be asked to consider may not be familiar to them because, unlike many companies with shares traded on the Nasdaq Capital Market ("Nasdaq"), the Company is incorporated under the laws of England and Wales and is therefore subject to the U.K. Companies Act 2006 (the "Companies Act"). The Companies Act obliges the Company to propose certain matters to shareholders for approval that would generally not be subject to periodic approval by shareholders of companies incorporated in the United States but would be considered routine items for approval by shareholders of companies incorporated in England and Wales.

Such authority shall expire at the conclusion of the Company's next annual general meeting.

This authority shall apply from the conclusion of the Annual General meeting until a date which is five years from the date of the Annual General Meeting.

Explanatory notes to the resolutions

Resolution 1 (U.K. Annual Report and Accounts 2023)

The Board is required to present at the Annual General Meeting the U.K. Annual Report and Accounts for the financial year ended 31 December 2023, including the Directors' Report and the Auditor's Report on the U.K. Annual Report and Accounts and on those parts of the Directors' Remuneration Report which have been audited.

Resolution 1 is an advisory vote and in accordance with its obligations under English law, the Company will provide shareholders at the Annual General Meeting with the opportunity to receive the U.K. Annual Report and Accounts and ask any relevant and appropriate questions on the U.K. Annual Report and Accounts of the Board and or auditors in attendance at the Annual General Meeting.

Resolution 2 (directors' annual remuneration report)

Resolution 2 is an advisory vote to approve the directors' annual remuneration report for the year ended 31 December 2023. The directors' remuneration report is set out on pages 35 to 36 and 50 to 61 of the U.K. Annual Report and Accounts. It provides information on the remuneration of the directors for 2023 and that proposed for 2024; it includes a statement by the Chairman of the Compensation Committee but excludes the Remuneration Policy which was approved by shareholders at the AGM in 2022.

Resolution 3 (authority for certain donations and expenditure)

The Company is seeking authority under this resolution to allow the Company and any of its subsidiaries to make political donations or incur political expenditure up to a limit of £100,000 for each category of donation or expenditure set out in the resolution. It is not the Company's policy or intention to make political donations or expenditures, and no political donations were made in the year ended 31 December 2023. However, it is possible that certain routine activities undertaken by the Company and its subsidiaries might unintentionally fall within the scope of the provisions controlling political donations and expenditure, which are very broad and open to interpretation. Any political donations or expenditure regulated by the Companies Act must be approved by shareholders at a general meeting and must be disclosed in the annual report for the year ending 31 December 2024. Accordingly, in common with many other UK public companies, the directors seek shareholders' approval for political donations and expenditure to be made by the Company and its subsidiaries, to avoid inadvertently contravening the Companies Act. The authority being sought will take effect from the end of the Annual General Meeting until the end of next year's annual general meeting (or, if earlier, 15 months from the date of the Annual General Meeting), until renewed, revoked or varied by the Company in a general meeting.

Resolution 4 (authority to make purchases of own shares off-market)

The Board considers that share buybacks are an important means of returning value to shareholders, managing capital resources and maximizing sustainable long-term growth in earnings per share.

As the Nasdaq is not a recognized investment exchange for the purposes of section 693(2) of the Companies Act, any repurchases by Ferroglobe of its own shares on or through Nasdaq would constitute "off-market" repurchases for the purposes of the Companies Act. Such repurchases may only be made pursuant to a form of share repurchase contract, the terms of which have been approved by shareholders in accordance with section 694 of the Companies Act.

Ferroglobe is seeking the approval by shareholders of off-market purchases in accordance with this resolution in order to enable share repurchases on or through Nasdaq pursuant to section 694 of the Companies Act, provided that (i) the maximum aggregate number of ordinary shares hereby authorized to be purchased is 37,776,463, representing approximately 20% of the issued ordinary share capital), and (ii) additional restrictions under applicable U.S. securities laws are substantially complied with, including (but not limited to) the pricing limitations under Rule 10b-18(b)(3) of the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"), the volume limitations under Rules 10b-18(b)(4) and 10b-18(c)(2) of the Exchange Act, the timing limitations under Rules 10b-18(b)(2) and 10b-18(c)(1) and the requirements with respect to the use of brokers or dealers under Rule 10b-18(b)(1) of the Exchange Act.

This resolution specifies the counterparties which may each enter into a separate repurchase contract with Ferroglobe, in each case in the form approved by the shareholders. Repurchases may be undertaken following a specific, one- off instruction from the Company to the counterparty or pursuant to a share trading plan under which the Company instructs the counterparty to purchase a set number of shares at a maximum and/or minimum price over a set period of time.

3

The approval of the terms of the form of share repurchase contract, if granted, will be valid until the fifth anniversary of the date of approval. However, if this resolution is approved, the Company may agree to purchase ordinary shares pursuant to any such contract, even if such purchase would, or might, be completed or executed wholly or partly after the authority ends and the Company may purchase such ordinary shares pursuant to any such contract as if the authority had not ended.

It is common for English incorporated public limited companies to have a standing authority that would permit the making of share repurchases should the Company be able and decide to do so in the future. The Board considers that having the right to make such repurchases would be in the Company's and its shareholders' best interests. A market announcement would be made if the Company did decide to commence repurchases in accordance with this authority.

Under the Companies Act, ordinary shares bought back may be held in treasury or may be cancelled. Shares held in treasury may be either sold for cash or transferred for the purposes of an employee shares scheme. Ferroglobe therefore has a choice of either holding or cancelling any shares it may purchase. If Ferroglobe buys back any of its shares under this resolution, we will decide at the time of purchase whether to cancel them immediately or to hold them in treasury. In relation to treasury shares, we would also have regard to any investor guidelines regarding the purchase of shares intended to be held in treasury and their holding or resale. In the event that (i) the Company repurchases the maximum number of shares possible pursuant to this authority, (ii) its majority shareholder, Grupo Villar Mir S.A.U. ("GVM"), does not participate in the share purchase program and (iii) all shares purchased are cancelled, the percentage holding of GVM in the Company may increase to a maximum of 50.1%.

Copies of the forms of contracts which shareholders are being asked to approve will be made available for shareholders to inspect at Ferroglobe's registered office at 5 Fleet Place, London, EC4M 7RD for the period from 3 June 2024 until the date of the AGM. Copies of the forms of contracts will also be available for inspection at the Annual General Meeting.

Resolutions 5 to 15 (directors seeking re-election)

In line with best practice in corporate governance, all our directors retire annually and, if agreed with them that they will continue in office, they offer themselves for re-election by the shareholders. Any director appointed by the Board since the last Annual General Meeting must stand for election at the next Annual General Meeting.

The biographies of the directors standing for re-election at the Annual General Meeting are set out below to enable shareholders to make an informed decision on their re-election. The biographies give the date of appointment of each director to the Board or Committees of Ferroglobe.

Under the Companies Act, the remuneration of the Company's U.K. statutory auditor must be fixed in a general meeting or in such manner as may be determined in a general meeting.

1. Some of the resolutions are items that are required to be approved by shareholders periodically under the Companies Act and generally do not have an analogous requirement under United States laws and regulations. As such, while these resolutions may be familiar and routine to shareholders accustomed to being shareholders of companies incorporated in England and Wales, other shareholders may be less familiar with these routine resolutions and should review and consider each resolution carefully.
2. In accordance with the Articles, all resolutions will be taken on a poll. Voting on a poll will mean that each Ordinary Share represented in person or by proxy will be counted in the vote.
3. All resolutions will be proposed as ordinary resolutions, which means that such resolutions must be passed by a simple majority of the total voting rights of shareholders who vote on such resolutions, whether in person or by proxy. The results of the shareholders' vote on resolutions 1 and 2 regarding receipt of the U.K. Annual Report and Accounts and approval of the Directors' Annual Remuneration Report will not require the Board or any committee thereof to take (or refrain from taking) any action. The Board values the opinion of shareholders as expressed through such resolutions and will carefully consider the outcome of the votes on these resolutions.
4. Shareholders of record are entitled to attend, speak and vote at the Annual General Meeting. "Shareholders of record" are those persons registered in the register of members of the Company in respect of Ordinary Shares at 23:59 (British Summer Time) on 21 May 2024. If, however, Ordinary Shares are held for you in a stock brokerage account or by a broker, bank or other nominee, you are considered the "beneficial owner" of those Ordinary Shares.
5. Beneficial owners of Ordinary Shares as at 23:59 (British Summer Time) on 21 May 2024 have the right to direct their broker or other agent on how to vote the Ordinary Shares in their account and are also invited to attend the Annual General Meeting. However, as beneficial owners are not Shareholders of record of the relevant Ordinary Shares, they may not vote their Ordinary Shares at the Annual General Meeting unless they request and obtain a legal proxy from their broker or agent.
6. If two or more shareholders jointly hold shares in the Company, each shareholder may attend, speak and vote at the Annual General Meeting. However, if more than one joint holder votes, the only vote will count is the vote of the joint holder whose name is listed first on the register of members of the Company.

1. Any Shareholder of record attending the Annual General Meeting has the right to speak and to ask questions.
2. In accordance with the provisions of the Companies Act, and in accordance with the Articles, a Shareholder of record who is entitled to attend and vote at the Annual General Meeting is entitled to appoint another person as his or her proxy to exercise all or any of his or her rights to attend and to speak and vote at the Annual General Meeting and to appoint more than one proxy in relation to the Annual General Meeting (provided that each proxy is appointed to exercise the rights attached to different Ordinary Shares). Such proxies need not be Shareholders of record, but must attend the Annual General Meeting and vote as the Shareholder of record instructs. Further details regarding the process to appoint a proxy, voting and the deadlines therefor are set out in the "Voting Process and Revocation of Proxies" section below.
3. Pursuant to section 527 of the Companies Act 2006, shareholders meeting the threshold requirements set out in that section have the right to require the Company to publish on a website a statement setting out any matter relating to:
4. 1. the audit of the Company's accounts (including the auditor's report and the conduct of the audit) that are to be laid before the AGM; or
   2. any circumstance connected with an auditor of the Company ceasing to hold office since the previous meeting at which annual accounts and reports were laid in accordance with section 437 of the Companies Act 2006.

The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with sections 527 or 528 of the Companies Act 2006. Where the Company is required to place a statement on a website under section 527 of the Companies Act 2006, it must forward the statement to the Company's auditor no later than the time when it makes the statement available on the website. The business which may be dealt with at the AGM includes any statement that the Company has been required under section 527 of the Companies Act 2006 to publish on a website.

1. The results of the polls taken on the resolutions at the Annual General Meeting and any other information required by the Companies Act will be made available on the Company's website as soon as reasonably practicable following the AGM and for a period of two years thereafter.
2. A copy of this Annual General Meeting notice can be found at the Company's website, www.ferroglobe.com.
