Hunting PLC 5 Hanover Square London W1S 1HQ

3 March 2022

To holders of the Company's Ordinary shares

Dear Shareholder

On behalf of my fellow Directors, I am pleased to inform you of the Company's AGM which will be held at The Royal Automobile Club, 89 Pall Mall, London SW1Y 5HS on Wednesday 20 April 2022 at 1.30p.m. The formal Notice of AGM is set out on pages 6 to 8 of this document. The purpose of this letter is to explain the business of the AGM in more detail and the arrangements for the meeting proposed by the Directors.

AGM Arrangements

The meeting is planned to be an open meeting with shareholders welcome to attend. If you would like to vote on the resolutions but cannot come to the AGM, please either (i) fill in the form of proxy sent to you with this document and return it to the Company's Registrars; or (ii) submit your proxy voting instructions via the internet at www.sharevote.co.uk; or (iii) if you are a CREST member, lodge the CREST Proxy Instruction using the CREST Proxy Voting Service, in all cases so as to be received no later than 1.30p.m. on Monday 18 April 2022.

Prior to the formal business of the AGM, a presentation will be delivered by the Chief Executive. At the end of the presentation questions relevant to the business of the AGM, and those submitted by shareholders ahead of the AGM, will be answered.

Access to the presentation and the AGM can also be made through the internet link:

https://webcasting.buchanan.uk.com/broadcast/61f2d15912956e448c99524a

Given that the Company intends to hold an open meeting, shareholders planning to attend the AGM are encouraged to take a lateral flow test prior to travelling to the AGM. Subject to government requirements at the date of the meeting, shareholders are also requested to wear a mask during the AGM.

Questions and Answers

The Directors have made available to shareholders the ability to submit questions relevant to the business of the AGM ahead of the AGM. These questions will be answered in the form of a presentation noted above. Shareholders are therefore asked to submit all questions, in relation to the business to be considered at the AGM by Monday 18 April 2022, to the Company's Registered Office, for the attention of the Company Secretary. Alternatively, questions can be submitted via email at agm@hunting.plc.uk. Shareholders should note the provisions on page 10 of this document in relation to questions and answers.

AGM Resolutions

Resolutions 1 to 13 contained within the Notice of AGM are proposed as ordinary resolutions. This means that for each of those resolutions to be passed, more than half of the votes cast must be in favour of the resolution. Resolutions 14 to 17 are proposed as special resolutions. This means that for each of those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolution.

Voting on all resolutions at the AGM will be on a poll as the Directors believe that this will result in a more accurate reflection of the views of all shareholders and ensure that their votes are recognised, whether or not they are able to attend the AGM. On a poll, each shareholder has one vote for every share held. The results of the poll and proxy votes cast prior to the AGM will be released, shortly after the AGM, to the London Stock Exchange and published on the Company's website at www.huntingplc.com.

Resolution 1 – Presentation of Accounts

The Directors are required by the Companies Act 2006 to present to the shareholders of the Company at a general meeting the Company's audited accounts for the year ended 31 December 2021, together with the Directors' reports (including the strategic report) and the auditor's report on those accounts.

Resolution 2 – Annual Report on Remuneration

The Companies Act 2006 requires the Company to seek shareholder approval, on an annual basis, for the Annual Report on Remuneration for the prior financial year and the accompanying letter from the Chair of the Remuneration Committee. The vote on this Report and letter is "advisory" which means that payments to the Directors are not conditional on this resolution being approved. The Annual Report on Remuneration is set out on pages 121 to 130 of the Company's 2021 Annual Report and Accounts and the letter from the Chair of the Remuneration Committee can be found on pages 107 to 109.

A key decision of the Remuneration Committee has been to apply a consistent and fair approach to remuneration in 2021 and to make no adjustments to the fixed or variable pay structures for the workforce, leadership team and executive Directors. Hunting operates in a highly cyclical sector and the Remuneration Committee believes that the current remuneration framework and the Company's Remuneration Policy align closely to overall stakeholder expectations.

Resolution 3 – Final Dividend

Shareholders are asked to approve a recommended final dividend of 4.0 cents for each Ordinary share for payment on 13 May 2022 to those shareholders who are on the register of members at the close of business on 22 April 2022. This is in addition to the interim dividend of 4.0 cents for each Ordinary share that was paid on 29 October 2021, making a total of 8.0 cents for the year for each Ordinary share.

Resolution 4 – Appointment of Director

Shareholders are asked to approve the appointment of Paula Harris as a Director of the Company. On 3 March 2022 the Company announced that Ms Harris has been proposed as a new independent non-executive Director. Subject to shareholder approval, Ms Harris will join the Board of the Company at the conclusion of the AGM. Biographical details of Ms Harris and the Board's reasons for proposing her appointment, in accordance with the recommendations of the UK Corporate Governance Code, are detailed on page 12.

Resolutions 5 to 10 – Re-election of Directors

In accordance with the recommendations of the UK Corporate Governance Code, all other Directors will stand for re-election at the AGM, with the exception of Richard H Hunting who will retire as a Director at the conclusion of the AGM.

Biographical details of each of the Directors can be found in Appendix 1 on pages 11 and 12 of this document. In accordance with the recommendations of the UK Corporate Governance Code, the reasons for re-election and contribution of each Director have been detailed.

The Board is confident that each non-executive Director has the necessary skills and expertise required for the Hunting Group, including significant energy industry experience and/or knowledge of the legal and regulatory environment to which Hunting is required to comply. The Board is also satisfied that each non-executive Director, remains independent in character and judgement and is free from any relationship or circumstance which is likely to affect, or could appear to affect, his or her judgement.

Resolution 11 – Auditor's re-appointment

The resolution seeks shareholder approval for the re-appointment of Deloitte LLP as auditor. The performance and effectiveness of the auditor were evaluated by the Company's Audit Committee, which recommended to the Board that Deloitte LLP be re-appointed. Deloitte LLP has also indicated its willingness to continue as the Company's auditor for another year.

Resolution 12 – Auditor's remuneration

The resolution gives the Audit Committee the authority to determine the remuneration of the Company's auditor for the year ended 31 December 2021.

Resolution 13 – Authority to the Directors to allot shares

The Companies Act 2006 provides that the Directors may only allot shares or grant rights to subscribe for or convert any security into shares if authorised by shareholders to do so. Resolution 13 will, if passed, authorise the Directors to allot new shares up to an aggregate nominal amount of £27,490,014, which represents an amount that is approximately two-thirds of the issued share capital of the Company as at 3 March 2022, being the latest practicable date prior to the publication of this document.

As provided in paragraph (a) of the resolution, up to half of this authority (equal to one-third of the issued share capital of the Company) will enable the Directors to allot and issue new shares in whatever manner (subject to pre-emption rights) they see fit. Paragraph (b) of the resolution provides that the remainder of the authority (equal to a further one-third of the issued share capital of the Company) may only be used in connection with a rights issue in favour of Ordinary shareholders. As paragraph (a) imposes no restrictions on the way the authority may be exercised, it could be used in conjunction with paragraph (b) so as to enable the whole two-thirds authority to be used in connection with a rights issue.

The authority will expire at the earlier of the date that is 15 months after the date of the passing of the resolution or the conclusion of the next AGM of the Company.

Passing resolution 13 will ensure that the Directors continue to have the flexibility to act in the best interests of shareholders, when opportunities arise, by issuing new shares. There are no current plans to issue new shares except in connection with employee share schemes.

As at 3 March 2022, the Company had 164,940,082 Ordinary shares of 25 pence each in issue.

Resolutions 14 and 15 – Disapplication of statutory pre-emption rights

Resolutions 14 and 15 seek shareholder approval such that the Board, subject to resolution 13 being passed, be authorised to allot equity securities (as defined in the Companies Act 2006) for cash under the authority given by these resolutions and/or to sell Ordinary shares held by the Company as treasury shares for cash, as if section 561 of the Companies Act 2006 did not apply to any such allotment or sale. The authorities in resolutions 14 and 15 are limited to a combined aggregate amount of 10% of the Company's issued Ordinary share capital, as at 3 March 2022, being the latest practicable date prior to the publication of this document.

Resolution 14 seeks shareholder approval to disapply statutory pre-emption rights up to 5% of the Company's issued Ordinary share capital. This part of the authority is designed to provide the Directors with flexibility to raise further equity funding and to pursue acquisition opportunities as and when they might arise. Resolution 14 also gives the Directors flexibility to implement a rights issue, open offer or other pre-emptive issue on terms that do not strictly reflect statutory pre-emption rights where strict compliance would be unduly burdensome (for example, due to overseas securities laws).

Resolution 15 seeks shareholder approval to disapply statutory pre-emption rights in respect of an additional 5% of the Company's issued Ordinary share capital. In accordance with the Pre-Emption Group's Statement of Principles Disapplying Statutory Pre-Emption Rights, the Directors confirm that this additional authority will be used only in connection with an acquisition or specified capital investment that is announced contemporaneously with the issue, or that has taken place in the preceding six-month period and is disclosed in the announcement of the issue.

These authorities will expire at the earlier of the date that is 15 months after the date of the passing of the relevant resolution or the conclusion of the next AGM of the Company. In each case, prior to its expiry the Company may make offers, and enter into agreements, which would, or might, require equity securities to be allotted (and treasury shares to be sold) after the relevant authority expires and the Board may allot equity securities (and sell treasury shares) under any such offer or agreement as if the authority had not expired.

In respect of these authorities, the Directors also confirm their intention to follow the provisions of the Pre-Emption Group's Statement of Principles regarding cumulative usage of disapplication authorities within a rolling three-year period where the Principles provide that excluding any shares issued in connection with an acquisition or specified capital investment as described above, usage in excess of 7.5% of the issued Ordinary share capital of the Company (excluding treasury shares) should not take place without prior consultation with shareholders.

Resolution 16 – Purchase of own shares by the Company

If passed, this resolution will grant the Company authority for a period of up to 15 months after the date of passing of the resolution to buy its own shares in the market. The resolution limits the number of shares that may be purchased to 14.99% of the Company's issued Ordinary share capital as at 3 March 2022, being the latest practicable date prior to the publication of this document. The price per Ordinary share that the Company may pay is set at a minimum amount (excluding expenses) of 25 pence per Ordinary share and a maximum amount (excluding expenses) of the higher of:

• (i) 5% above the average of the previous five days' middle market prices; and
• (ii) the higher of the price of the last independent trade and the highest current independent bid on the trading venue where the purchase is carried out.

This authority will only be exercised if market conditions make it advantageous to do so.

The Directors' present intention is that shares purchased pursuant to this authority will be cancelled immediately on purchase. Alternatively, the shares may be held in treasury, sold for cash or (provided Listing Rule requirements are met) transferred for the purposes of or pursuant to an employee share scheme. The effect of any cancellation would be to reduce the number of shares in issue. For most purposes, while held in treasury, shares are treated as if they have been cancelled (for example, they carry no voting rights and do not qualify for dividends). The Directors will only make purchases under this authority if they believe that the effect of such purchases (where such shares are purchased for cancellation) would result in increased earnings per share and would be in the interests of the shareholders generally.

As at 3 March 2022, there were outstanding options and awards to subscribe for 9,544,636 Ordinary shares representing in total approximately 5.8% of the Company's issued share capital at that date. If the authority to purchase shares was exercised in full, and those shares were cancelled (but the Company's issued share capital otherwise remained unaltered), outstanding options and awards to subscribe for Ordinary shares would, as at that date, represent approximately 6.8% of the Company's issued share capital.

Resolution 17 – Notice of General Meetings

To enable the Company to preserve the ability to call general meetings (other than a AGM) on 14 clear days' notice, the Company must offer all shareholders the opportunity to appoint a proxy electronically (via the website of the Company or its Registrars) and must obtain the approval of its shareholders by means of a special resolution passed each year. Resolution 17 seeks such approval which, if granted, will be effective until the Company's next AGM when it is intended that a similar resolution will be proposed. The Company is in compliance with the requirement to make electronic voting available to all shareholders. It is intended that the flexibility to call general meetings on 14 clear days' notice will only be used for non-routine business and where merited in the interests of shareholders as a whole.

Recommendation

The Directors consider that all the resolutions to be put to the AGM are in the best interests of the Company and its shareholders as a whole. The Board will be voting in favour of them and unanimously recommends that you do so as well.

Yours sincerely,

John F. Glick Chairman

Proxies and corporate representatives

1. A member who is an individual is entitled to attend, speak and vote at the AGM or to appoint one or more other persons as their proxy to exercise all or any of their rights on their behalf. Further details of how to appoint a proxy, and the rights of proxies, are given in the paragraphs below.

A member that is a company can appoint one or more corporate representatives (such as a Director or employee of the company) whose attendance at the AGM is treated as if the company were attending in person, or it can appoint one or more persons as its proxy to exercise all or any of its rights on its behalf. In each case, a person attending the AGM will need to provide the Company or its Registrars, Equiniti Limited, with evidence of their identity and, if applicable, their appointment as a proxy or corporate representative with authority to vote on behalf of a member.

• 1. A shareholder may appoint more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder. A proxy need not be a shareholder of the Company. To appoint a proxy or proxies, shareholders must:
• (a) complete a form of proxy, sign it and return it, together with the power of attorney or other authority (if any) under which it is signed, or a notarially certified copy of such authority, to the Company's Registrars, Equiniti Limited;
• (b) submit a proxy electronically at www.sharevote.co.uk; or (c) transmit a CREST Proxy Instruction (as set out in note 11 below);

In all cases so that it is received no later than 1.30p.m. on Monday 18 April 2022. To appoint more than one proxy, you will need to complete a separate form of proxy in relation to each appointment. A form of proxy for use in connection with the AGM is enclosed with this document.

Full details of the procedure to submit a proxy electronically are given on the website at www.sharevote.co.uk. To use this service, you will need your Voting ID, Task ID and Shareholder Reference Number printed on the form of proxy. If you do not have a form of proxy and believe that you should, please contact the Company's Registrars, Equiniti Limited, at Aspect House, Spencer Road, Lancing, West Sussex BN99 6DA or call on 0371 384 2173. Overseas shareholders should call on +44 (0)121 415 7047. Lines are open 8.30 a.m. to 5.30 p.m. Monday to Friday (excluding UK public holidays).

• 1. If you are appointing more than one proxy you will need to state clearly on each form of proxy the number of shares in relation to which the proxy is appointed and ensure that, taken together, the number of shares stated on the forms of proxy do not exceed your holding.
• 1. The appointment of a proxy will not prevent a shareholder attending the AGM and voting in person if he/she wishes to do so.
• 1. In the case of joint holders, where more than one of the joint holders purports to appoint a proxy, only the appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in the Company's register of members in respect of the joint holding (the first-named being the most senior).

Nominated Persons

• 1. Any person to whom this Notice is sent who is a person nominated under section 146 of the Companies Act 2006 to enjoy information rights (a "Nominated Person") may, under an agreement between him/her and the shareholder by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights.
• 1. The statement of the rights of shareholders in relation to the appointment of proxies in notes 1, 2 and 3 above does not apply to Nominated Persons. The rights described in these notes can only be exercised by shareholders of the Company.

Entitlement to attend and vote

1. Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001, the Company gives notice that only those shareholders included in the register of members of the Company at 6.30 p.m. on Monday 18 April 2022 or, if the AGM is adjourned, in the register of members at 6.30 p.m. on the day which is two days before the day of any adjourned AGM, will be entitled to attend and to vote at the AGM in respect of the number of shares registered in their names at that time. Changes to entries in the register of members after 6.30 p.m. on 18 April 2022, or, if the AGM is adjourned, after 6.30 p.m. on the day which is two days before the day of the adjourned AGM, will be disregarded in determining the rights of any person to attend or vote at the AGM.

Total voting rights

1. As at 9.00 a.m. on 3 March 2022, the Company's issued share capital comprised 164,940,082 Ordinary shares of 25 pence each. Each Ordinary share carries the right to one vote at a general meeting of the Company and, therefore, the total number of voting rights in the Company as at 9.00 a.m. on 3 March 2022 is 164,940,082.

Crest members and institutional investors

• 1. CREST members who wish to appoint a proxy or proxies by utilising the CREST electronic proxy appointment service may do so for the AGM and any adjournment(s) of the AGM by using the procedures described in the CREST Manual (available via www.euroclear.com). CREST personal members or other CREST sponsored members, and those CREST members who have appointed a service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.
• 1. In order for a proxy appointment or instruction made by means of the CREST service to be valid, the appropriate CREST message (a "CREST Proxy Instruction") must be properly authenticated in accordance with Euroclear UK & Ireland Limited's ("EUI") specifications, and must contain the information required for such instruction, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or is an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by the Company's agent Equiniti Limited (RA19), by the latest time for receipt of proxy appointments set out in note 2 above. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the Company's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.
• 1. CREST members and, where applicable, their CREST sponsors or voting service providers, should note that EUI does not make available special procedures in CREST for any particular messages.
