To shareholders of Nanoco Group plc

Dear shareholder,

Annual General Meeting – 13 January 2026

I have pleasure in inviting you to the 2025 Annual General Meeting (the "Meeting" or the "AGM") of Nanoco Group plc (the "Company"), which will be held at The Heath Conference Centre, The Heath Business and Technical Park, Runcorn WA7 4QX, at 11.00 a.m. on 13 January 2026. This document includes the Notice of AGM, which sets out the resolutions that shareholders are being asked to consider and vote on (the "Resolutions").

Virtual attendance at the Meeting

The Company understands and respects the importance of the AGM to shareholders and the Board greatly values the opportunity to meet shareholders in person. However, we understand that this may not be possible or desirable for all who wish to attend; therefore, the Company will offer shareholders the option to participate in the Meeting remotely via a conference call facility that can be accessed from any computer with internet access or through a telephone (mobile or landline). If you wish to use this facility, please register at https://brrmedia.news/NANO_AGM26. After verification of their identity, details of how to join the conference call will be provided to each shareholder who has registered. However, shareholders will not be able to vote at the Meeting when joining via conference call. Shareholders are therefore asked, whether or not they propose to attend the AGM, to exercise their votes and appoint the Chairman of the Meeting as their proxy by completing the Proxy Form sent to them with this document and returning it to our registrars as soon as possible. They must receive it by 11.00 a.m. on 9 January 2026 (or, in circumstances where the AGM is adjourned to a date later than 48 hours after the time specified for the Meeting, 48 hours before the time of the adjourned Meeting, excluding any UK non-working days). Any questions should be submitted in advance of the Meeting by emailing such questions to the Company Secretary at LGray@nanocotechnologies.com.

Further details and guidance can be found in note 1 to the Notice of AGM set out below. Shareholders should also continue to monitor the Company's website and announcements for any updates regarding the AGM.

The purpose of this document is to set out the background to and reasons for the Resolutions which are to be proposed at the AGM and to explain why the Directors consider them to be in the best interests of the Company and shareholders and recommend that you vote in favour of the Resolutions.

Certain Resolutions cross-refer to the Annual Report and Accounts. A copy of the Annual Report and Accounts is available for inspection on the Company's website at www.nanocotechnologies.com.

Explanation of the business of the Meeting

The business to be conducted at the Meeting reflects the ordinary business and related Ordinary Resolutions and Special Resolutions that are put to the Annual General Meeting of the Company each year.

Detailed explanatory notes on all of the business to be considered at this year's AGM are set out below.

Resolutions numbered 1 to 11 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 numbered 12 to 15 are proposed as Special Resolutions. This means that for each of those Resolutions to be passed, at least three-quarters (75%) of the votes cast must be in favour of the Resolution.

To more accurately reflect the views of shareholders of the Company, voting on all of the Resolutions will be carried out by way of a poll put to the Meeting in accordance with Article 10.11 of the Company's Articles of Association adopted by Special Resolution on 22 April 2015 (as amended, the "Company's Articles"). The Board of Directors of the Company (the "Board") considers this to be best practice as it gives all shareholders the opportunity to participate in the decision making of the Company and have their votes recorded even if they are unable to attend the Meeting in person.

Ordinary Resolutions (1 to 11)

Resolution 1 – Approval of reports and accounts

The Companies Act 2006 (the "2006 Act") requires the directors of a public company to lay before the company in a general meeting copies of its annual report and accounts in respect of each financial year prior to the end of the period for filing those reports and accounts. Resolution 1 deals with the receipt by the shareholders of the Company's audited accounts and the reports of the Directors of the Company (the "Directors") and the auditors for the year ended 31 July 2025.

Resolutions 2 and 3 – Re-appointment of auditors and auditors' remuneration

The auditors of the Company must be submitted for re-appointment at each general meeting at which the accounts are laid to serve from the conclusion of that meeting until the conclusion of the next such meeting. Resolution 2 proposes the re-appointment of Mazars LLP, the Company's existing auditors, as auditors of the Company until the conclusion of the next meeting. Resolution 3 gives authority to the Board to determine the auditors' remuneration.

Resolutions 4 to 9 – Re-election and election of Directors

Resolutions 4 to 9 deal, respectively, with the re-election of Dr Jalal Bagherli, Dmitry Shashkov, Liam Gray, Dr Alison Fielding, Chris Batterham and Dieter May as Directors. Notwithstanding the Company's Articles, which require all Directors to submit themselves for re-election: (i) if they have been in office for more than three years since their appointment or last appointment; (ii) if they have held office at the time of the two preceding Annual General Meetings and did not retire at either of them; or (iii) (in respect of Non-Executive Directors only) if they have held office for a continuous period of nine years or more at the date of the relevant Annual General Meeting, the Directors recognise the importance of sound corporate governance and have therefore determined, in accordance with the recommendations of the latest UK Corporate Governance Code (the "Code") published by the UK Financial Reporting Council on 16 July 2018, that all Directors will submit themselves for re-election each year at the Company's Annual General Meeting. Separate Resolutions will be proposed at the Meeting for each re-election.

Dr Jalal Bagherli, Dmitry Shashkov, Liam Gray, Dr Alison Fielding, Chris Batterham and Dieter May are therefore acting in accordance with the Code and, being eligible, will retire voluntarily and submit themselves for re-election.

Following an assessment of the performance of each individual Director, the Nominations Committee has confirmed to the Board that each Director continues to make an effective and valuable contribution and that they demonstrate excellent commitment to their respective roles. The Board therefore supports the re-election of Dr Jalal Bagherli, Dmitry Shashkov, Liam Gray, Dr Alison Fielding, Chris Batterham and Dieter May pursuant to Resolutions 4 to 9 inclusive.

Biographical details of all the Directors can be found on pages 50 and 51 of the Annual Report and Accounts and on the Company's website.

Resolution 10 – Approval of Directors' remuneration report

The 2006 Act requires quoted companies, at each general meeting at which statutory accounts are to be laid, to propose an ordinary resolution approving the directors' remuneration report for the year (the "Remuneration report"). Shareholders will be asked to approve the content of the Company's Remuneration report, including the Annual statement by the Chairman of the Remuneration Committee, for the financial year ended 31 July 2025. A copy of the Remuneration report is included in the Annual Report and Accounts on pages 73 to 87. The vote is advisory in nature and does not affect the actual remuneration paid to any individual Director.

Resolution 11 – Authority of the Directors to issue and allot new ordinary shares

The existing authority granted to the Directors by shareholder resolution at the Annual General Meeting held on 21 January 2025 to allot shares in the Company in accordance with section 551 of the 2006 Act expires at the conclusion of the AGM.

The authority given to the Directors to allot further shares in the capital of the Company requires the prior authorisation of the shareholders in a general meeting under section 551 of the 2006 Act. Upon the passing of Resolution 11, the Directors will have authority (pursuant to paragraph (a) of Resolution 11) to allot ordinary shares in the capital of the Company ("Ordinary Shares") (and other relevant securities, as defined within section 551 of the 2006 Act) up to an aggregate nominal amount of £6,518,127, which is approximately one-third of the Company's issued Ordinary Share capital as at 4 December 2025, being the latest practicable date before the publication of this document.

In addition, in accordance with guidance from the Investment Association ("IA") on the expectations of institutional investors in relation to the authority of directors to allot shares, which the Directors believe it is appropriate for the Company to follow, upon the passing of Resolution 11, the Directors will have authority (pursuant to paragraph (b) of Resolution 11) to allot, including the Ordinary Shares referred to in paragraph (a) of Resolution 11, Ordinary Shares (and other relevant securities, as defined within section 551 of the 2006 Act) in connection with a fully pre-emptive rights issue, open offer or otherwise in favour of ordinary shareholders up to an aggregate nominal amount of £13,036,254, as reduced by the nominal amount of any shares issued under paragraph (a) of Resolution 11. This amount (before any reduction) represents approximately two-thirds of the Company's current issued Ordinary Share capital as at 4 December 2025, being the latest practicable date before the publication of this document.

Ordinary Resolutions (1 to 11) continued

Resolution 11 – Authority of the Directors to issue and allot new ordinary shares continued

As a result, if Resolution 11 is passed, the Directors could allot shares representing up to two-thirds of the current issued share capital of the Company pursuant to a fully pre-emptive rights issue, open offer or otherwise.

Although the Directors have no present intention to exercise this authority other than in connection with the exercise of options granted pursuant to the Company's employee share schemes, it is considered desirable to give the Directors the maximum flexibility permitted by corporate governance guidelines to respond to market developments and to enable allotments to take place to finance business opportunities in the interests of the Company as a whole.

This authority will, if granted, expire on the conclusion of the next Annual General Meeting of the Company to be held after the passing of the Resolution or, if earlier, 15 months from the date of the passing of the Resolution, unless such authority is renewed prior to this time. The Directors intend to renew such power at successive Annual General Meetings of the Company in accordance with current best practice.

Special Resolutions (12 to 15)

Resolutions 12 and 13 – Disapplication of statutory pre-emption rights

The existing authority granted to the Directors by shareholder resolution at the Annual General Meeting held on 21 January 2025 to allot shares for cash pursuant to sections 570 and 573 of the 2006 Act expires at the conclusion of the AGM.

If the Directors wish to exercise the authority under Resolution 11 and allot shares (or sell any shares which the Company currently holds and/or may subsequently purchase and elect to hold as treasury shares) for cash, the 2006 Act requires that unless shareholders have given specific authority for the waiver of their statutory pre-emption rights, the shares must be offered first to existing shareholders in proportion to their existing shareholdings. In certain circumstances, it may be in the best interests of the Company to allot new shares (or to grant rights over shares) for cash or to sell treasury shares for cash without first offering them to existing shareholders in proportion to their holdings.

Resolution 12 would, if passed, authorise the Directors to do this by allowing the Directors to allot shares for cash or sell treasury shares for cash: (i) by way of a rights issue (subject to certain exclusions), or by way of an open offer or other offer of securities (not being a rights issue) in favour of existing shareholders in proportion to their shareholdings (subject to certain exclusions); or (ii) otherwise up to an aggregate nominal value of £977,719, which is equivalent to approximately 5% of the Company's issued Ordinary Share capital (excluding shares held in treasury) as at 4 December 2025, being the latest practicable date before the publication of this document, in each case, without the shares first being offered to existing shareholders in proportion to their existing holdings.

In addition to the authority granted by Resolution 12, Resolution 13 authorises Directors to allot equity shares up to an aggregate of £977,719, being approximately 5% of the Company's issued Ordinary Share capital as at 4 December 2025, for cash pursuant to the authority contained in Resolution 11 where that allotment is in connection with an acquisition or specified capital investment which is announced contemporaneously with the issue, or which has taken place in the preceding six-month period and is disclosed in the announcement of the issue.

The authority to issue up to an aggregate 10% of the issued Ordinary Share capital of the Company is below the limits provided for in the guidance from the Pre-Emption Group's revised statement of principles published in November 2022 (the "PEG Principles") which allows companies to seek authority for an issue of shares for cash otherwise than in connection with a pre-emptive offer to include: (i) an authority up to 10% of a company's issued share capital for use on an unrestricted basis; and (ii) an additional authority up to a further 10% of a company's issued share capital for use in connection with an acquisition or a specified capital investment announced contemporaneously with the issue, or that has taken place in the twelve-month period preceding the announcement of the issue. In both cases, an additional authority of up to 2% may be sought for the purposes of making a follow-on offer. The Board has decided not to increase the authority up to an aggregate 20% of the issued Ordinary Share capital of the Company, or seek the additional authority of up to 2%, as the Board believes the current authority of up to an aggregate 10% provides the Company with sufficient flexibility to undertake non-pre-emptive issuances.

Resolutions 12 and 13 are proposed as separate Special Resolutions in compliance with the best practice guidance issued by the Pre-Emption Group.

The Directors confirm that it is intended that a maximum of £977,719 (representing 5% of the Company's issued share capital) will be available (pursuant to Resolution 12) for general purposes and that it will only allot shares with a nominal value in excess of £977,719 for cash pursuant to the authority conferred in Resolution 13 where that allotment is in connection with an acquisition or specified capital investment (as described in the PEG Principles) which is announced contemporaneously with the issue, or which has taken place in the preceding six-month period and is disclosed in the announcement of the issue.

Special Resolutions (12 to 15) continued

Resolutions 12 and 13 – Disapplication of statutory pre-emption rights continued

Although the Directors have no present intention to exercise the authorities conferred by Resolutions 12 and 13 other than in connection with the exercise of options granted pursuant to the Company's employee share schemes, it is considered prudent to give the Directors additional flexibility and the opportunity to finance expansion opportunities as and when they arise in the interests of the Company as a whole.

Each of the authorities conferred by Resolution 12 and Resolution 13, if granted, will expire on the conclusion of the next Annual General Meeting of the Company to be held after the passing of such Resolution or, if earlier, 15 months from the date of the passing of such Resolution, unless such authorities are renewed prior to this time.

The Directors intend to seek renewal of the powers conferred by Resolutions 12 and 13 at subsequent Annual General Meetings of the Company in accordance with current best practice.

Resolution 14 – Authority of the Company to purchase its own shares

The existing authority granted to the Directors by shareholder resolution at the General Meeting held on 21 January 2025 to purchase the Company's own shares will expire at the conclusion of the AGM.

The Directors consider that it would be beneficial if, in certain circumstances, the Company had the power to purchase its own Ordinary Shares for the purposes of returning surplus funds to shareholders and providing a return on investments. The Directors therefore consider that it would be beneficial for the shareholders as a whole if the Company were to be granted the flexibility to repurchase its own shares.

Accordingly, the Directors recommend that the existing power to purchase Ordinary Shares (in defined circumstances) up to a maximum prescribed limit be renewed for a further limited period.

The Company will only make such purchases if the Directors are satisfied, after careful consideration, that these are in the best interests of the Company and shareholders generally and could be reasonably expected to result in an increase in expected earnings per share. Furthermore, account will be taken of the overall financial implications for the Company.

If such purchases of its own shares were made, the Company would be able to do either, or a combination, of the following:

• (a) cancel the purchased Ordinary Shares so reducing the total number of Ordinary Shares in issue; or
• (b) where the Ordinary Shares were purchased out of distributable profits, subject to certain limitations, hold them as treasury shares.

Treasury shares themselves may be cancelled, sold for cash or transferred for the purposes of the Company's share schemes. The statutory pre-emption rights apply to a sale of treasury shares for cash, and the disapplication of the statutory pre-emption rights in Resolutions 12 and 13 include, within the authorised amount, any sales of treasury shares for cash which may occur.

Finally, if such purchases were made, to the extent the purchased shares are held as treasury shares, any increase in earnings per share would only be temporary, until the shares in question were either cancelled, sold or transferred out of treasury.

Resolution 14 authorises the Directors to purchase up to a maximum of 19,554,381 Ordinary Shares, representing approximately 10% of the Company's issued Ordinary Share capital as at 4 December 2025, and provides that the maximum price per Ordinary Share payable on any exercise of the authority shall be the higher of: (i) an amount equal to 105% of the average of the market value for an Ordinary Share as derived from the Daily Official List of the London Stock Exchange for the five business days prior to making any such purchase; and (ii) an amount equal to the higher of the price of the last independent trade and the highest current bid on the London Stock Exchange at the time the purchase is carried out. The minimum price payable shall be 10 pence per Ordinary Share, being the nominal value of an Ordinary Share. For this purpose, both the maximum and minimum prices permitted to be paid are exclusive of expenses.

As at 4 December 2025, being the latest practicable date before the publication of this document, the number of Ordinary Shares in respect of which options have been granted and which remain outstanding (and on the assumption that all conditions to the exercise of such options will be satisfied) is 14,754,097 (constituting approximately 7.55% of the current issued Ordinary Share capital of the Company as at 4 December 2025). If the Company were to buy back the maximum number of Ordinary Shares permitted pursuant to Resolution 14, then the total number of options to subscribe for Ordinary Shares (on the assumptions set out above) outstanding as at 4 December 2025 represents approximately 8.38% of the reduced issued share capital.

This authority, if granted, will expire on the conclusion of the next Annual General Meeting of the Company to be held after the passing of the Resolution or, if earlier, 15 months from the date of the passing of the Resolution, unless such authority is renewed prior to this time.

The Board intends to seek renewal of this power at subsequent Annual General Meetings of the Company in accordance with current best practice.

Special Resolutions (12 to 15) continued

Resolution 15 – Reduced notice of general meetings (other than Annual General Meetings)

Resolution 15 will be proposed to enable the Company to call general meetings (other than Annual General Meetings) on 14 clear days' notice. Changes made to the 2006 Act by the Companies (Shareholders' Rights) Regulations 2009 (the "Shareholders' Rights Regulations") increase the required notice period for general meetings from 14 clear days to 21 clear days, unless shareholders approve a shorter notice period, which cannot be less than 14 clear days. Annual General Meetings will continue to be held on 21 clear days' notice. Resolution 15 seeks approval to retain the flexibility available before the Shareholders' Rights Regulations came into force on 3 August 2009. It is intended that the shorter notice will only be used where it would clearly be to the advantage of shareholders as a whole and it would not normally be used where the proposals to be put before the meeting are not time sensitive. The approval will be effective until the next Annual General Meeting of the Company after the passing of the Resolution, when it is intended that a similar resolution will be proposed. Note that in order to take advantage of the reduced notice period of 14 clear days, the Company must make a means of electronic voting available to all shareholders for that meeting.

Explanatory notes

The following notes explain your general rights as a shareholder and your rights to attend and vote at the AGM or to appoint someone else to vote on your behalf.

• 1. The Company understands and respects the importance of the AGM to shareholders and the Board greatly values the opportunity to meet shareholders in person. However, we understand that this may not be possible or desirable for all who wish to attend; therefore, the Company will offer shareholders the option to participate in the Meeting remotely via a conference call facility that can be accessed from any computer with internet access or through a telephone (mobile or landline). If you wish to use this facility, please register at https://brrmedia.news/NANO_AGM26. After verification of the shareholder's identity, details of how to join the conference call will be provided to each shareholder who has registered. Please note that shareholders will not be able to use this facility to actively participate in the Meeting by voting on the Resolutions or asking questions. Therefore, the Board:
• | encourages shareholders to submit their votes via proxy as early as possible, and shareholders should appoint the Chairman of the Meeting as their proxy. All proxy appointments should be received by no later than 11.00 a.m. on 9 January 2026 (or, in circumstances where the AGM is adjourned to a date later than 48 hours after the time specified for the Meeting, 48 hours before the time of the adjourned Meeting, excluding any UK non-working days);
• | strongly recommends CREST members to vote electronically through the CREST electronic proxy appointment service as your vote will automatically be counted;
• | proposes that voting at the Meeting will be conducted by means of a poll on all Resolutions, with each shareholder having one vote for each share held, thereby allowing all those proxy votes submitted and received prior to the Meeting to be counted; and
• | encourages you to submit any question that you would like to be answered at the Meeting by emailing such questions to the Company Secretary at LGray@nanocotechnologies.com, so that they are received by no later than 12 noon on 9 January 2026. The Company will endeavour to respond to all questions received from shareholders at the AGM or within seven days following the AGM.
• 1. As permitted by Regulation 41 of the Uncertificated Securities Regulations 2001, shareholders who hold shares in certificated or uncertificated form must be entered on the Company's relevant share register (the "Register") at 6.00 p.m. on 9 January 2026 (the "Specified Time") in order to be entitled to attend and vote at the AGM. Such shareholders may only cast votes in respect of Ordinary Shares held at such time. Changes to entries on the relevant Register after that time shall be disregarded in determining the rights of any person to attend or vote at the Meeting. Should the AGM be adjourned to a time not more than 48 hours after the Specified Time, that time will also apply for the purpose of determining the entitlement of members to attend and vote (and for the purpose of determining the number of votes they may cast) at the adjourned AGM. Should the AGM be adjourned for a longer period, then to be so entitled, members must be entered on the Register at 6.00 p.m. on the date which is 48 hours before the time fixed for the adjourned AGM, excluding any UK non-working days or, if the Company gives notice of the adjourned AGM, at the time specified in the Notice.
• 1. Any member entitled to attend and vote at the AGM is entitled to appoint a proxy to attend, speak and vote instead of the member. A member 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 Ordinary Share or Ordinary Shares of the member; however, please see note 1 in regard to appointing the Chairman as proxy. Completion and return of a Proxy Form will not preclude a member from attending the AGM either in person or virtually, should he/she subsequently decide to do so.
• 1. The right to appoint a proxy does not apply to persons whose Ordinary Shares are held on their behalf by another person and who have been nominated to receive communications from the Company in accordance with section 146 of the 2006 Act ("Nominated Persons"). Nominated Persons may have a right under an agreement with the registered shareholder who holds the Ordinary Shares on their behalf to be appointed (or to have someone else appointed) as a proxy. Alternatively, if Nominated Persons do not have such a right, or do not wish to exercise it, they may have a right under such an agreement to give instructions to the person holding the Ordinary Shares as to the exercise of voting rights.
• 1. In order to be valid, any Proxy Form and power of attorney or other authority under which it is signed, or a notarially certified or office copy of such power or authority, must reach the Company's registrars, Neville Registrars Limited, in accordance with the instructions set out on the Proxy Form not less than 48 hours (excluding non-working days) before the time of the AGM (11.00 a.m. on 9 January 2026 or, in circumstances where the AGM is adjourned to a date later than 48 hours after the Specified Time, 48 hours before the time of the adjourned Meeting, excluding any UK non-working days).
• 1. A Proxy Form accompanies this Notice of AGM. Details of how to appoint a proxy are set out in the notes to the Proxy Form. If a member wishes to appoint more than one proxy and so requires additional Proxy Forms, the member can photocopy the Proxy Form.
• 1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the AGM and any adjournments of it by using the procedures described in the CREST Manual. CREST personal members or other CREST sponsored members, and those CREST members who have appointed voting service providers, should refer to their sponsors or voting service providers, who will be able to take the appropriate action on their behalf.
• 7.1 For a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a "CREST Proxy Instruction") must be properly authenticated in accordance with Euroclear UK & International's specifications and must contain the information required for those instructions as described in the CREST Manual (available via www.euroclear.com/CREST). The message, regardless of whether it relates to the appointment of a proxy or to an amendment to the instruction given to the previously appointed proxy, must, to be valid, be transmitted so as to be received by the Company's agent (ID: 7RA11) by the latest time for receipt of proxy appointments specified in the Notice of AGM. 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.
• 7.2 CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear UK & International does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will, therefore, apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed voting service providers, to procure that its CREST sponsors or voting service providers take) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.
• 7.3 The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.
• 1. Members should note that it is possible that, pursuant to requests made by shareholders of the Company under section 527 of the 2006 Act, the Company may be required to publish on a website a statement setting out any matter relating to: (i) the audit of the Company's accounts (including the Independent auditors' report and the conduct of the audit) that are to be laid before the AGM; or (ii) any circumstance connected with auditors 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 2006 Act. The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with section 527 or 528 of the 2006 Act. Where the Company is required to place a statement on a website under section 527 of the 2006 Act, it must forward the statement to the Company's auditors not 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 2006 Act to publish on a website.
• 1. Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a member provided that they do not do so in relation to the same Ordinary Shares.
• 1. In order to facilitate voting by corporate representatives at the Meeting, arrangements will be put in place at the Meeting so that: (i) if a corporate shareholder has appointed the Chairman of the Meeting as its corporate representative with instructions to vote on a poll in accordance with the directions of all of the other corporate representatives for that shareholder at the Meeting, then on a poll those corporate representatives will give voting directions to the Chairman and the Chairman will vote (or withhold a vote) as corporate representative in accordance with those directions; and (ii) if more than one corporate representative for the same corporate shareholder attends the Meeting but the corporate shareholder has not appointed the Chairman of the Meeting as its corporate representative, a designated corporate representative will be nominated, from those corporate representatives who attend, who will vote on a poll and the other corporate representatives will give voting directions to that designated corporate representative. Corporate shareholders are referred to the guidance issued by the Institute of Chartered Secretaries and Administrators on proxies and corporate representatives (www.icsa.org.uk) for further details of this procedure. The guidance includes a sample form of representation letter if the Chairman is being appointed as described in (i) above.
• 1. To change a proxy instruction, a member needs to submit a new proxy appointment using the methods set out above. Note that the deadlines for receipt of proxy appointments (11.00 a.m. on 9 January 2026 or, in circumstances where the AGM is adjourned to a date later than 48 hours after the Specified Time, 48 hours before the time of the adjourned Meeting, excluding any UK non-working days) also apply in relation to amended instructions and any amended proxy appointment received after the relevant deadline will be disregarded. Where a member has appointed a proxy using the paper Proxy Form and would like to change the instructions using another such form, that member should contact the Company's registrars, Neville Registrars Limited, on 0121 585 1131; lines are open 9.00 a.m. to 5.00 p.m. Monday to Friday. If more than one valid proxy appointment is submitted, the appointment received last before the deadline for the receipt of proxies will take precedence.

Explanatory notes continued

• 1. In order to revoke a proxy instruction, a signed letter clearly stating a member's intention to revoke a proxy appointment must be sent by post or by hand to the Company's registrars, Neville Registrars Limited, in accordance with the instructions on the Proxy Form. Note that deadlines for receipt of proxy appointments (11.00 a.m. on 9 January 2026 or, in circumstances where the AGM is adjourned to a date later than 48 hours after the Specified Time, 48 hours before the time of the adjourned Meeting, excluding any UK non-working days) also apply in relation to revocations and any revocation received after the deadline will be disregarded.
• 1. In the event that a member is a joint holder and the joint holder purports to appoint a proxy, only the appointment submitted by the member whose name appears first on the register will be accepted.
• 1. The "Vote Withheld" option on the Proxy Form is provided to enable a member to abstain on any particular Resolution. It should be noted that an abstention is not a vote in law and will not be counted in the calculation of the proportion of votes "For" or "Against" a particular Resolution.
• 1. The total number of Ordinary Shares of 10 pence in issue as at 4 December 2025, being the latest practicable date before the publication of this Notice of AGM, was 195,543,816 Ordinary Shares carrying one vote each. This is also the total level of voting rights in the Company.
• 1. Copies of the service contracts and letters of appointment of each of the Directors of the Company, will be available for inspection at the registered office of the Company during usual business hours on any weekday (Saturdays, Sundays and public holidays excluded) from the date of this Notice until the date of the AGM and at the place of the AGM from at least 15 minutes prior to and until the conclusion of the AGM. A copy of this Notice of Annual General Meeting will be available for inspection at the Company's registered office for not less than 15 days ending with the date of the Annual General Meeting, at the Annual General Meeting, and at http://www.nanocotechnologies.com/investor-relations/shareholder-services/annual-general-meetinginformation until the conclusion of the Annual General Meeting.
• 1. Any member attending the AGM has the right to ask questions. It would be helpful if members could state their name before asking a question. The Company must cause to be answered any question relating to the business to be dealt with at the Meeting put by a member attending the Meeting. However, members should note that no answer need be given in the following circumstances:
• (a) if to do so would interfere unduly with the preparation of the Meeting or would involve a disclosure of confidential information;
• (b) if the answer has already been given on a website in the form of an answer to a question; and/or
• (c) if it is undesirable, in the interests of the Company or the good order of the Meeting, that the question be answered.
• 1. Any electronic address provided either in this Notice of AGM or in any related documents (including the Proxy Form) may not be used to communicate with the Company for any purposes other than those expressly stated.
• 1. As required by section 311A of the 2006 Act, this Notice of AGM, together with information about the total number of Ordinary Shares and voting rights in the Company in respect of which members are entitled to exercise voting rights at the Meeting as at 6.00 p.m. on 4 December 2025, being the latest practicable date before the publication of this Notice of AGM, and, if applicable, any members' statements, members' resolutions or members' matters of business received by the Company after the date of this Notice of AGM, will be available on the Company's website, www.nanocotechnologies.com.
