Dear Shareholder

2017 Annual General Meeting of Shareholders of Ferroglobe PLC (“Ferroglobe” or the “Company”)

I am pleased to invite you to attend Ferroglobe’s annual general meeting of its shareholders (the “Annual General Meeting”), to be held at 2:00 p.m. (British Summer Time) on Wednesday, 28 June 2017 at Brown’s Hotel, 19 Dover Street, London W1S 4LW, United Kingdom. The accompanying notice of Annual General Meeting describes the meeting, the resolutions you will be asked to consider and vote upon, and related matters.

Your vote is important, regardless of the number of shares you own. Whether or not you intend to attend the Annual General Meeting, please vote as soon as possible to make sure that your shares are represented. You may vote via the internet, by phone, or by mail by signing, dating and returning your proxy card in the envelope provided.

Recommendation

Except for Resolution 15, we consider all resolutions proposed to shareholders at the Annual General Meeting to be standard business. Resolution 15 relates to proposed changes to the Articles of Association of the Company to allow Pedro Larrea Paguaga, Ferroglobe’s Chief Executive Officer, to be appointed to the Company’s board of directors (the “Board”). You will find an explanation of each resolution within the Explanatory Notes on pages five to nine of this pack. The Board considers that all the resolutions to be put to the Annual General Meeting are in the best interests of the Company and its shareholders as a whole and are most likely to promote the success of the Company. The Board unanimously recommends that you vote “for” each of the proposed resolutions, as the members of the Board intend to do in respect of their beneficial holdings.

Thank you for your continued support of Ferroglobe.

Yours sincerely,

Javier López Madrid

Executive Chairman

NOTICE OF 2017 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 Wednesday, 28 June 2017 at 2:00 p.m. (British Summer Time) at Brown’s Hotel, 19 Dover Street, London W1S 4LW, United Kingdom (“U.K.”).

The business of the Annual General Meeting will be to consider and, if thought fit, pass the resolutions below. Resolutions 1 to 14 will be proposed as ordinary resolutions, and Resolution 15 will be proposed as a special resolution. Explanations of the resolutions are given in the explanatory notes on pages 5 to 9 of this Annual General Meeting notice and additional information for those entitled to attend the Annual General Meeting can be found on pages 10 to 13. 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 (“Shareholders”) will be asked to consider may not be familiar to them because, unlike many companies with shares traded on the NASDAQ markets, 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.

Resolution 11 (appointment of auditor)

At each general meeting at which accounts are laid before the Shareholders, the Company is required to appoint an auditor to serve until the next such meeting. Deloitte LLP has served as the Company’s U.K. statutory auditor since 3 February 2016.

If this resolution does not receive the affirmative vote of a majority of the shares entitled to vote and present in person or represented by proxy at the Annual General Meeting, the Board may appoint an auditor to fill the vacancy.

Resolution 12 (remuneration of auditor)

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. The Company is asking its Shareholders to authorise the Audit Committee to determine the remuneration of Deloitte LLP in its capacity as the Company’s U.K. statutory auditor under the Companies Act.

Resolution 13 (authority to purchase own shares)

Further to approval of the Incentive Plan by the Annual General Meeting of the Shareholders on 29 June 2016, a resolution will be proposed to authorise the Company to make purchases of its shares pursuant to the terms of the Incentive Plan and the Companies Act. Under the Companies Act, any purchases by a company of its own shares on an exchange which has neither its registered office nor its head office in the U.K. (including NASDAQ), are considered “off‑market” purchases. In order to aid implementation of the Incentive Plan, the directors consider it prudent for the Company to have the flexibility to effect off‑market purchases of its own shares in the future.

Under the terms of the resolution, the Company will be generally authorised to make market purchases of up to 5,000,000 shares with an aggregate nominal value of US$50,000, representing approximately 3% of the total issued share capital of the Company as at 26 May 2017, the latest practicable date prior to the date of this notice. The maximum price payable per share will be based on the market price of an Ordinary Share as set out in more detail in the resolution itself. The minimum price payable per share, exclusive of expenses, is its nominal value.

If approved, the authority will expire on the fifth anniversary of the date of approval.

Resolution 14 (political donations)

Under sections 366 and 367 of the Companies Act, the Company is required to seek Shareholders’ authority to make any political donations and/or incur political expenditure in the European Union.

5

Although the Company does not make, and does not intend to make, donations to political parties and/or to independent election candidates within the normal meaning of that expression, the legislation is very broadly drafted and may encompass activities such as: funding seminars and other functions to which politicians are invited; supporting certain bodies involved in policy review and law reform; and matching employees’ donations to certain charities.

Therefore, in accordance with current best practice, the directors have decided to propose an ordinary resolution to authorise the Company and its subsidiaries to make certain types of political donations and/or expenditure, as more particularly described in the resolution, up to an aggregate amount of £100,000.

Resolution 15 (amendment of the Articles)

The Articles currently provide for a total of nine directors, of whom five are nominated by Grupo VM and the remainder are Independent Directors (defined in the Articles as Donald G. Barger, Jr., Stuart E. Eizenstat, Bruce L. Crockett and any other director appointed by the Independent Directors or the Board under Article 25.4 who qualifies as an independent director under NASDAQ rules). There are currently only eight directors (following the resignation of Alan Kestenbaum, who was an Independent Director), five of whom are Grupo VM nominees. There is therefore a vacancy for an Independent Director and the process of identifying a suitable additional Independent Director to join the Board is well advanced.

In addition to filling the current Board vacancy, the Board has unanimously decided that it would be in the interests of the Company to appoint Pedro Larrea Paguaga, the Chief Executive Officer of the Company, to the Board. It is common for a Chief Executive Officer to sit on the Board of an English company and this will enable the Board to benefit directly from Mr. Larrea Paguaga’s detailed knowledge of the business in its deliberations. His biography is set out below.

Pedro Larrea Paguaga has served as the Chief Executive Officer since 23 December 2015. He was Chairman and CEO of FerroAtlántica from December 2012, and served in that role until the closing of the Business Combination. He joined FerroAtlántica as CEO in 2011. Before joining FerroAtlántica, he worked for 13 years (1996 to 2009) at Endesa, the biggest power company in Spain and Latin America, where he reached the position of Chairman and CEO of Endesa Latinoamérica, with total revenues above €8 billion and EBITDA above €3 billion. He served on the Board of Directors of Enersis (2007 to 2009) and Endesa Chile (1999 to 2002 and 2006 to 2007), both public Chilean companies listed on the NYSE. Mr. Larrea Paguaga has also worked in management consulting firms PwC (2010 to 2011), where he led the energy sector practice in Spain, and McKinsey & Company in Spain, Latin America and the United States (1989 to 1995). Mr. Larrea Paguaga holds a Mining Engineer degree (MSc equivalent) from Universidad Politécnica de Madrid (graduating with honors). He also holds an M.B.A. from INSEAD, where he obtained the Henry Ford II award for academic excellence.

In order to appoint Mr. Larrea Paguaga as an additional director, it is necessary to amend the Articles to increase the maximum number of directors from nine to ten. The Board has resolved that if the proposed amendments to the Articles are approved, he will be appointed immediately on conclusion of the Annual General Meeting to fill the vacancy and would hold office until the next annual general meeting, whereupon he would come up for re‑election in the same manner as other Board members. For the purposes of the Articles, he would not be treated as a Grupo VM nominee or an Independent Director.

Further Notes:

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. Resolutions 1 to 14 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’ 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 resolutions 1 and 2.

6

4. Resolution 15 will be proposed as a special resolution, which means that such resolution must be passed by a majority of not less than 75% of the total voting rights of Shareholders who vote on such resolution, whether in person or by proxy.

5. “Shareholders of record” are those persons registered in the register of members of the Company in respect of Ordinary Shares at 2.00 p.m. (British Summer Time) on 5 May 2017. 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.

6. Beneficial owners of Ordinary Shares as at 2.00 p.m. (British Summer Time) on 5 May 2017 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.

7. Any Shareholder of record attending the Annual General Meeting has the right to ask questions. The Company must cause to be answered any questions put by a Shareholder of record attending the meeting relating to the business being dealt with at the Annual General Meeting unless to do so would interfere unduly with the business of the meeting, be undesirable in the interests of the Company or the good order of the meeting, involve the disclosure of confidential information, or if the information has already been given on the Company’s website.

8. 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.

9. 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 Annual General Meeting and for a period of two years thereafter.

10. A copy of this Annual General Meeting notice can be found at the Company’s website, www.ferroglobe.com.

11. Recipients of this notice and the accompanying materials may not use any electronic address provided in this notice or such materials to communicate with the Company for any purposes other than those expressly stated.

12. To be admitted to the Annual General Meeting, please bring the Admission Ticket that you will have received through the post. You will need to be able to provide your photo identification at the registration desk.

13. On arrival at the Annual General Meeting venue, all those entitled to vote will be required to register and collect a poll card. In order to facilitate these arrangements, please arrive at the Annual General Meeting venue in good time. You will be given instructions on how to complete your poll card at the Annual General Meeting.

VOTING PROCESS AND REVOCATION OF PROXIES

If you are a Shareholder of record, there are three ways to vote by proxy:

● By Internet – You can vote over the Internet at www.envisionreports.com/FGLO by following the instructions at such web address. You will need to enter your control number, which is a 15‑digit number located in a box on your proxy card. We encourage you to vote by Internet even if you received this Annual General Meeting notice in the mail.

● By Telephone – You may vote and submit your proxy by calling toll‑free 1‑800‑652‑8683 in the United States and providing your control number, which is a 15‑digit number located in a box on your proxy card.

● By Mail – If you received this Annual General Meeting notice by mail or if you requested paper copies of the Annual General Meeting notice, you can vote by mail by marking, dating, signing and returning the proxy card in the postage‑paid envelope.

7

Telephone and Internet voting facilities for Shareholders of record will be available 24 hours a day and will close at 2:01 p.m. (British Summer Time) on Monday, 26 June 2017. Submitting your proxy by any of these methods will not affect your ability to attend the Annual General Meeting in‑person and vote at the Annual General Meeting.

If your shares are held in “street name”, meaning you are a beneficial owner with your shares held through a bank or brokerage firm, you will receive instructions from your bank or brokerage firm, which is the Shareholder of record of your shares. You must follow the instructions of the Shareholder of record in order for your shares to be voted. Telephone and Internet voting may also be offered to Shareholders owning shares through certain banks and brokers, according to their individual policies.

The Company has retained Computershare to receive and tabulate the proxies.

If you submit proxy voting instructions and direct how your shares will be voted, the individuals named as proxies must vote your shares in the manner you indicate.

A Shareholder who has given a proxy may revoke it at any time before it is exercised at the Annual General Meeting by:

● attending the Annual General Meeting and voting in person;

● voting again by Internet or Telephone (only the last vote cast by each Shareholder of record will be counted), provided that the Shareholder does so before 2:01 p.m. (British Summer Time) on Monday, 26 June 2017.

● delivering a written notice, at the address given below, bearing a date later than that indicated on the proxy card or the date you voted by Internet or Telephone, but prior to the date of the Annual General Meeting, stating that the proxy is revoked; or
