Each shareholder may be asked to present valid photo identification, such as a driver’s license or passport. Shareholders holding shares in brokerage accounts or by a bank or other nominee may be required to show a brokerage statement or account statement reflecting share ownership as of the Record Date. In order to attend and participate in the AGM virtually, you will need to visit www.virtualshareholdermeeting.com/GFS2023 and you will be required to enter the 15-digit control number included on your Notice of Internet Availability of Proxy Materials (“Notice of Internet Availability”), on your proxy card (if you received a printed copy of the proxy materials), or on the instructions that accompanied your proxy materials to access the meeting. If you are the beneficial owner of shares held in “street name” (that is, you hold your shares through a broker, bank or other holder of record), you must register in advance to gain access to the AGM and obtain a proxy issued in your name from that holder of record in order to vote your shares or ask questions during the AGM.

To vote virtually at the meeting, visit www.virtualshareholdermeeting.com/GFS2023 and log in using the aforementioned information. Shareholders will have the opportunity to ask questions at the AGM during designated periods. On or about June 23, 2023, we first mailed to our shareholders a Notice of Internet Availability containing instructions on how to access our proxy materials. The Notice of Internet Availability directs shareholders to a website where they can access our proxy materials, including our proxy statement and our annual report, and view instructions on how to vote via the Internet, mobile device or by proxy card. This process is designed to expedite shareholders’ receipt of proxy materials, lower the cost of the AGM, and help conserve natural resources. If you received a Notice of Internet Availability and would prefer to receive a paper copy of our proxy materials, please follow the instructions included in the Notice of Internet Availability. Record Date, Share Ownership and Quorum Only the holders of record of the ordinary shares of the Company as of the close of business on June 7, 2023, Eastern Time (the “Record Date”) are entitled to receive notice of and attend the AGM and any adjournment thereof. No

person shall be entitled to vote at the AGM unless registered as a shareholder of the Company on the Record Date for the AGM. As of the close of business on the Record Date, 552,115,498 ordinary shares were issued and outstanding. Shareholders holding in aggregate not less than one-third of all voting share capital of the Company in issue present in person or by proxy and entitled to vote constitutes a quorum of the shareholders. Status as a Foreign Private Issuer We are a “foreign private issuer” within the meaning of Rule 405 of the U.S. Securities Act of 1933, as amended, and Rule 3b-4 of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), and as a result, we are exempt from the U.S. Securities and Exchange Commission’s proxy rules under Rule 3a12-3(b) of the Exchange Act. However, recognizing that good corporate governance plays an important role in our overall success and in enhancing shareholder value, we have determined to voluntarily comply with certain best practice guidelines and to provide certain disclosures including this proxy statement. Voting and Solicitation Each ordinary share issued and outstanding as of the close of business on the Record Date is entitled to one vote at the AGM. The resolutions to be put to the vote at the AGM will be approved by an ordinary resolution (i.e. a majority of the votes cast, by or on behalf of, the shareholders who, being entitled to do so, attend and vote at the AGM). Internet Availability of Proxy Materials We are furnishing proxy materials to our shareholders primarily via the Internet, instead of mailing printed copies of those materials to each shareholder. Voting by Holders of Ordinary Shares Ordinary shares that are properly voted via the Internet, mobile device or for which proxy cards are properly executed and returned within the deadline set forth below, will be voted at the AGM in accordance with the directions given. The proxy holder will also vote in the discretion of such proxy holder on any other matters that may properly come before the AGM, or at any adjournment thereof. Where any holder of ordinary shares affirmatively abstains from voting on any particular resolution, the votes attaching to such ordinary shares will not be included or counted in the determination of the number of ordinary shares present and voting for the purposes of determining whether such resolution has been passed (but they will be counted for the purposes of determining the quorum, as described above). Shareholders of record attending the AGM in person will be given a ballot upon request. Voting via the Internet or by mobile device helps save money by reducing postage and proxy tabulation costs. Each of these voting methods is available 24 hours per day, seven days per week. To vote by any of these methods, read this proxy statement, have your Notice of Internet Availability or proxy card in hand, and follow the instructions set forth in the Notice of Internet Availability or proxy card, as the case may be. Proxies submitted by registered shareholders and street shareholders (whether by internet or by returning the proxy card) must be received by us no later than 11:59 p.m., Eastern time, on August 1, 2023 to ensure your representation at our AGM. The manner in which your shares may be voted depends on how your shares are held. If you own shares of record, meaning that your shares are represented by book entries in your name so that you appear as a shareholder on the shareholder register of the Company maintained by American Stock Transfer & Trust Company, LLC (“AST”) (i.e., you are a registered shareholder), our stock transfer agent, this proxy statement, the notice of AGM and the proxy card will be available to you at www.proxyvote.com by inserting the 15-digit control number on the Notice of Internet Availability or proxy card to be provided to you by AST. You may provide voting instructions by Internet, mobile device or (if you have received paper copies of our proxy materials) by returning a proxy card. You also may attend the AGM either in person or virtually and vote during the meeting. To vote virtually at the meeting, visit

www.virtualshareholdermeeting.com/GFS2023 and log in using the aforementioned information. Shareholders of record attending the AGM in person will be given a ballot upon request. Shareholders will have the opportunity to ask questions at the AGM during designated periods. If you own ordinary shares of record and you do not vote by Internet, mobile device, in person or by proxy or at the AGM, your shares will not be voted. If you own shares in street name (i.e., you are a street shareholder), meaning that your shares are held by a bank, brokerage firm, or other nominee, you are then considered the “beneficial owner” of shares held in “street name,” and as a result, this proxy statement, the notice of AGM and the proxy card will be available to you at www.proxyvote.com by inserting the 15-digit control number on the instructions to be provided to you by your bank, brokerage firm, or other nominee holding the shares. You may provide voting instructions by the Internet, mobile device or (if you have received paper copies of proxy materials through your bank, brokerage firm, or other nominee) by returning a voting instruction form received from that institution. If you own ordinary shares in street name and attend the AGM, you must obtain a “legal proxy” from the bank, brokerage firm, or other nominee that holds your shares in order to vote your shares at the meeting and present your voting information card. Duly appointed proxyholders attending the AGM in person will be given a ballot upon request. Revocability of Proxies Registered shareholders may revoke their proxy or change voting instructions before shares are voted at the AGM by submitting a written notice of revocation to our Investor Relations Department at ir@gf.com, or a duly executed proxy (via the Internet, mobile device or by returning a proxy card) bearing a later date (which must be received by us no later than the date set forth below) or by attending the AGM in person or virtually and voting during the meeting. A beneficial owner owning ordinary shares in street name may revoke or change voting instructions by contacting the bank, brokerage firm, or other nominee holding the shares or by obtaining a legal proxy from such institution and voting in person at the AGM. If you are not planning to attend our AGM, to ensure your representation at our AGM, any changes to the voting instructions of proxies previously submitted by registered shareholders and street shareholders (whether by internet or by mailing a proxy card) must be received by us no later than 11:59 p.m., Eastern time, on August 1, 2023. Broker Non-Votes and Abstentions Broker non-votes occur when brokers holding shares in street name for beneficial owners do not receive instructions from the beneficial owners about how to vote their shares and the broker is unable to vote the shares in its discretion in the absence of an instruction. An abstention occurs when a shareholder withholds such shareholder’s vote on a particular matter by checking the “ABSTAIN” box on the proxy card. Brokerage firms have the authority under the New York Stock Exchange rules to vote shares for which their customers do not provide voting instructions on routine matters. Following a narrowing of interpretation of the definition of a ‘routine matter,’ the only resolution that are now considered routine are the ratification of the selection of independent auditors. Your broker will NOT be able to vote your shares with respect to any other proposal or other matters considered at the AGM, unless you have provided instructions to your broker. We strongly encourage you to provide instructions to your broker to vote your shares and exercise your right as a shareholder. A vote will not be cast in non-routine matters in cases where a broker has not received an instruction from the beneficial owner. With respect to all of the proposals or other matters considered at the AGM, only those votes cast “FOR” or “AGAINST” are counted for the purposes of determining the number of votes cast with respect to each such proposal. Broker non-votes and abstentions are not considered votes cast and have no effect on the outcome of any of the proposals. Process for the Solicitation of Proxies We will pay the cost of soliciting proxies for the AGM. We may solicit by mail, telephone, personal contact and electronic means and arrangements are made with brokerage houses and other custodians, nominees and fiduciaries

to send the Information Notice, and if requested, Proxy Materials, to beneficial owners. Upon request, we will reimburse them for their reasonable expenses. In addition, our directors, officers and employees may solicit proxies, either in-person or by telephone, facsimile or written or electronic mail (without additional compensation). Shareholders are encouraged to return their proxies promptly.

Even if the selection is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and our shareholders.
