Key Terms

foreign private issuer, Record Date, broker non-votes, street name, +2 more

6 terms

foreign private issuer regulatory

"The Company is subject to the information reporting requirements ... applicable to foreign private issuers."

A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.

Record Date financial

"Shareholders of record holding Ordinary Shares as of the close of business on August 25, 2026 (the “Record Date”)"

The record date is the specific day when a company determines which shareholders are eligible to receive a dividend or participate in an upcoming vote. It’s like a cutoff date; if you own the stock on that day, you get the benefits or voting rights. This date matters because it decides who qualifies for certain company benefits.

broker non-votes financial

"A “broker non-vote” occurs when shares held by a broker in “street name” for a beneficial owner"

Broker non-votes occur when a brokerage firm is unable to vote on a shareholder’s behalf during a company election or decision because the shareholder has not given specific voting instructions, and the broker is not allowed or chooses not to vote on certain matters. They are important because they can affect the outcome of votes, especially when the results are close, by effectively reducing the total number of votes cast.

street name financial

"Beneficial owners holding in “street name” means that shares are held in the name of a bank, broker"

A "street name" is a way that stocks or other financial assets are registered under a broker's name rather than directly in an individual investor's name. This allows for easier buying, selling, and transferring of the assets, much like how a library might hold books on behalf of many readers. For investors, using a street name simplifies transactions and helps maintain privacy, but it also means the broker is the official record holder of ownership.

quorum regulatory

"A quorum must be present at the AGM in order for any business to be transacted."

A quorum is the minimum number of members needed to officially hold a meeting or make decisions. It ensures that decisions are made with enough participation to represent the group’s interests, much like a majority must be present for a vote to be valid. For investors, understanding quorum is important because it affects when and how important company or organization decisions can be legally made.

plurality of votes cast regulatory

"The resolution to be put to the vote at the AGM to elect directors will be approved by a plurality of votes cast"

PROXY STATEMENT
FOR THE ANNUAL GENERAL MEETING OF SHAREHOLDERS
TO BE HELD ON OCTOBER 8, 2026

This proxy statement (the “Proxy Statement”) is being furnished by and on behalf of the board of directors (the “Board” or the “Board of Directors”) of IHS Holding Limited (the “Company,” “we,” “us,” or “our”), in connection with our Annual General Meeting of Shareholders for the year ended December 31, 2026 (the “AGM”).

GENERAL INFORMATION ABOUT THE AGM AND VOTING

When and where will the AGM be held?

The AGM will be held at 1:00 pm, London time, on October 8, 2026 in person at the offices of IHS Holding Limited located at 1 Cathedral Piazza, 123 Victoria Street, London, SW1E 5BP, United Kingdom.

What is the purpose of the AGM?

The purpose of the AGM is to vote on the following item described in this Proxy Statement:

•

Proposal No. 1:   To elect each of the director nominees to serve until the annual general meeting for the year ended December 31, 2027 (the “2027 AGM”) or, in each case, until their earlier death, resignation, disqualification or removal.

​

Why are we holding the AGM?

As a matter of good corporate practice, and in compliance with the timing requirements of the Company’s second amended and restated memorandum and articles of association (the “Articles”), applicable corporate law and the New York Stock Exchange, we hold a meeting of shareholders annually. This proxy statement contains important information about us and the matters that will be voted on at the AGM. Please read these materials carefully so that you have the information you need to make informed decisions.

Are there any matters to be voted on at the AGM that are not included in this Proxy Statement?

At the date this Proxy Statement went to press, we did not know of any matters to be properly presented at the AGM other than those referred to in this Proxy Statement. If other matters are properly presented at the meeting or any adjournment or postponement thereof for consideration, and you are a shareholder of record and have submitted a proxy card, the persons named in your proxy card will have the discretion to vote on those matters for you.

Why did I receive a notice in the mail regarding the Internet availability of proxy materials instead of a paper copy of proxy materials?

We have elected to furnish proxy materials, including this Proxy Statement, to our shareholders who are beneficial owners by providing access to such documents on the Internet instead of mailing printed copies. Beneficial owners will not receive paper copies of the proxy materials unless they request them. Instead, on or about September 1, 2026, we mailed to our beneficial owners the Notice of Internet Availability of Proxy Materials and Proxy Card (the “Notice and Access Card”), which provides instructions on how to access and review on the Internet all of the proxy materials. The Notice and Access Card also instructs you as to how to authorize via the Internet your proxy to vote your shares according to your voting instructions. If you would like to receive a paper or email copy of our proxy materials, you should follow the instructions for requesting such materials described in the Notice and Access Card.

1

TABLE OF CONTENTS

What does it mean if I receive more than one Notice and Access Card or more than one set of proxy materials?

It means that your ordinary shares, par value $0.30 per share (“Ordinary Shares”) are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Notice and Access Card or set of proxy materials, please submit your proxy via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope. See “How do I vote my shares and what are the voting deadlines?” below for more information, including how to vote your shares at the AGM.

Who is entitled to vote at the AGM?

Shareholders of record holding Ordinary Shares as of the close of business on August 25, 2026 (the “Record Date”) are entitled to receive notice of, attend, and vote at the AGM and any postponement or adjournment thereof.

At the close of business on the Record Date, there were 338,340,734 of our Ordinary Shares issued and outstanding and entitled to vote. On the basis that voting at the AGM will be conducted by way of a poll, other than in respect of certain limitations and exceptions as detailed in the Articles, each Ordinary Share issued and outstanding as of the close of business on the Record Date is entitled to one (1) vote on each resolution at the AGM, subject to any limitations applicable to specific holders as set forth in the Articles.

You will need to obtain your own Internet access if you choose to vote over the Internet.

Can I vote my shares by filling out and returning the Notice and Access Card?

No. The Notice and Access Card identifies the items to be voted on at the AGM, but you cannot vote by marking the Notice and Access Card and returning it. If you are a beneficial owner and would like a paper proxy card, you should follow the instructions in the Notice and Access Card. The paper proxy card you receive will also provide instructions as to how to authorize via the Internet your proxy to vote your shares according to your voting instructions. Alternatively, you can mark the paper proxy card with how you would like your shares voted, sign the proxy card and return it in the envelope provided. See “How do I vote my shares and what are the voting deadlines?” below for more information, including how to vote your shares at the AGM.

What is the difference between being a “registered holder” and a “beneficial owner” ​(holding shares in “street name”)?

A registered holder (also called a “record holder”) holds shares in his or her name. Beneficial owners holding in “street name” means that shares are held in the name of a bank, broker or other nominee on the holder’s behalf.

What do I do if my shares are held in “street name”?

If your shares are held in a brokerage account or by a bank or other holder of record, you are considered the “beneficial owner” of shares held in “street name.” The Notice and Access Card or the proxy materials, if you have elected to receive a hard copy, have been forwarded to you by your broker, bank or other nominee who is considered, with respect to those shares, the shareholder of record. As the beneficial owner, you have the right to direct your broker, bank or other holder of record on how to vote your shares by following their instructions for voting. Please refer to information from your bank, broker or other nominee on how to submit your voting instructions.

How many shareholders must be present to hold the AGM?

A quorum must be present at the AGM in order for any business to be transacted. One or more shareholders holding at least one-third of the voting share capital of the Company present in person, or by proxy, and entitled to vote at the AGM shall form a quorum. If you sign and return your paper proxy card or authorize a proxy to vote electronically, your shares will be counted to determine whether we have a quorum even if you abstain or fail to vote as indicated in the proxy materials.

2

TABLE OF CONTENTS

What is a “vote withheld” and an abstention and how will “votes withheld” and abstentions be treated?

A “vote withheld” in the case of Proposal No. 1 or an abstention, in the case of other matters, represents a shareholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on Proposal No. 1.

What are “broker non-votes” and do they count for determining a quorum?

A “broker non-vote” occurs when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a proposal because (1) the broker has not received voting instructions from the shareholder who beneficially owns the shares and (2) the broker lacks the authority to vote the shares at their discretion. Under current stock exchange interpretations that govern broker non-votes, Proposal No. 1 is considered a non-routine matter, and a broker will lack the authority to vote uninstructed shares at their discretion on such proposal. Broker non-votes have no effect on the proposal and they will not be considered present for the purpose of determining whether there is a quorum for the AGM.

What if a quorum is not present at the AGM?

Under our Articles, if a quorum of shareholders is not present in person or by proxy within 30 minutes of the commencement of the AGM, the members of the Board of Directors present at the AGM may adjourn the AGM to a time and place as they may determine. If the directors do not exercise the authority to specify a date or time for the adjourned meeting, the adjourned meeting shall take place one (1) week after, and at the same time and place as the meeting from which the adjournment took place. If at an adjourned meeting a quorum is not present within half an hour from the time appointed for the meeting, the Shareholder or Shareholders present and entitled to vote shall form a quorum.

How do I vote my shares and what are the voting deadlines?

If you are a shareholder of record, there are three ways to vote:

•

by Internet — You can vote over the Internet at www.proxyvote.com by following the instructions on the Notice and Access Card or proxy card;

​

•

by Mail — You can vote by mail by signing, dating and mailing the proxy card to Broadridge Investor Communications Services (“Broadridge”) at the address specified on the proxy card; or

​

•

at the AGM — You can vote your shares during the AGM in person.

​

Internet voting facilities for shareholders of record will be available 24 hours a day and will close at 11:59 pm, Eastern time, on October 7, 2026. A proxy card sent by mail must be received prior to the time of the AGM. Even if you plan to attend the AGM, we encourage you to vote your shares by proxy. You may still vote your shares at the AGM even if you have previously voted by the methods described above or submitted your proxy.

If your shares are held in the name of a bank, broker or other holder of record, you will receive instructions on how to vote from the bank, broker or holder of record. You must follow the instructions of such bank, broker or holder of record in order for your shares to be voted.

How can I attend and vote at the AGM?

Shareholders of record holding Ordinary Shares as of the close of business on the Record Date are entitled to participate in the AGM by attending in person at the offices of IHS Holding Limited located at 1 Cathedral Piazza, 123 Victoria Street, London, SW1E 5BP, United Kingdom.

TABLE OF CONTENTS

representative) placed on the attendance list. Please note that the registration deadline is 5:00 pm, London time, on October 1, 2026. You should be prepared to provide a valid e-mail address, your name and control number.

If you hold your shares in “street name” and you plan to attend the AGM in person and vote your shares directly, you will need to notify your broker, bank or other holder of record of your intention to attend the AGM in person and to vote your shares directly, and they will send to you a legal proxy which gives you the authority to vote your shares directly at the AGM. In order to be admitted into the AGM and vote your shares directly, please go to http://www.proxyvote.com, enter the control number found on your legal proxy to access the voting page, then click “Attend the Meeting” link at the top of the page to have your name (or, if you are a corporation or other non-natural person, the name of your duly authorized representative) placed on the attendance list. Please note that the registration deadline is 5:00 pm, London time, on October 1, 2026. You should be prepared to provide a valid e-mail address, your name and control number listed on your legal proxy. Upon arriving at the AGM, you must present your legal proxy, along with a government-issued photo identification.

If you plan to attend the AGM in person and vote your shares directly but do not have a control number, you should register by emailing grouplegal@ihstowers.com and provide a valid e-mail address, your name and proof of ownership of ordinary shares as of the close of business on August 25, 2026, no later than 5:00 pm, London time, on October 1, 2026.

In order to be admitted into the AGM, individual shareholders must present government-issued photo identification (such as a driver’s license). In the case of a corporation, a resolution of the corporation’s directors or other governing body authorizing the attendance of the corporation’s representative should be presented, together with the representative’s government-issued photo identification. This is required so that it can be determined by reference to the register of members of the Company that you (or, if you are a corporation or other non-natural person, your duly authorized representative) are entitled to attend and vote at the AGM.

Check-in and registration for all in-person attendees on the day of the AGM will begin at 12:00 pm, London time. Please allow ample time for check-in.

How does the Board recommend that I vote?

The Board recommends that you vote:

FOR the election of each of the director nominees, to serve until the annual general meeting for the year ended December 31, 2027 (the “2027 AGM”) or, in each case, until their earlier death, resignation, disqualification or removal.

How many votes are required to approve the proposal?

The resolution to be put to the vote at the AGM to elect directors will be approved by a plurality of votes cast, represented in person or by proxy at the AGM.

What if I do not specify how my shares are to be voted?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are set forth above, as well as with the description of the proposal in this Proxy Statement.

Can I revoke or change my vote after I submit my proxy?

Yes. Whether you have voted by Internet, or mail, if you are a shareholder of record, you may change your vote and revoke your proxy by:

•

sending a written statement to that effect via electronic mail to IHSHolding@broadridge.com, provided such statement is received no later than October 7, 2026;

​

TABLE OF CONTENTS

•

voting again by Internet at a later time before the closing of those voting facilities at the time for holding the AGM;

​

•

submitting a properly signed proxy card per the instructions detailed above with a later date that is received no later than the time of the AGM; or

​

•

attending the AGM in accordance with the procedures and requirements set forth herein, revoking your proxy and voting again.

​

If you hold shares in street name, you may submit new voting instructions by contacting your bank, broker or other nominee. You may also change your vote or revoke your proxy in person at the AGM if you obtain a signed legal proxy from the record holder (broker, bank or other nominee) giving you the right to vote the shares directly.

Your most recent proxy card or Internet proxy is the one that is counted. Your attendance at the AGM by itself will not revoke your proxy unless you give written notice of revocation to the Company before your proxy is voted or you vote in person at the AGM.

Who will count the votes?

Representatives of Broadridge will tabulate the votes, and representatives of Broadridge will act as inspectors of election.

Where can I find the voting results of the AGM?

The voting results will be published following the AGM in a Report of Foreign Private Issuer on Form 6-K that will be furnished to the U.S. Securities and Exchange Commission (the “SEC”).

Who will pay for the cost of proxy solicitations for the AGM?

We will pay the cost of soliciting proxies. Proxies may be solicited on our behalf by directors, officers or employees (for no additional compensation) in person or by electronic transmission and facsimile transmission. Brokers and other nominees will be requested to solicit proxies or authorizations from beneficial owners and will be reimbursed for their reasonable expenses.

Will I be able to ask questions at the AGM?

As part of the AGM, we will hold a live Q&A session, during which we intend to answer appropriate questions submitted during the meeting and that relate solely to the matters to be voted on. We intend to reserve up to ten minutes before the closing of the polls to address questions submitted.

Who can help answer my questions about the AGM?

We have engaged MacKenzie Partners, Inc. to assist in the solicitation of proxies. This proxy solicitation is being made by the Company on behalf of the Board of the Company and will be paid for by the Company.

If you have any questions about the AGM or if you need additional copies of this proxy statement or the accompanying proxy card, you should contact our proxy solicitor, MacKenzie Partners, Inc., toll-free at 1-800-322-2885 or via email at proxy@mackenziepartners.com.
