Intention to delist from London Stock Exchange

Nanoco Group PLC

27 May 2026

 

THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION FOR THE PURPOSES OF ARTICLE 7 OF THE MARKET ABUSE REGULATION (596/2014/EU) AS THE SAME HAS BEEN RETAINED IN UK LAW AS AMENDED BY THE MARKET ABUSE (AMENDMENT) (EU EXIT) REGULATIONS (SI 2019/310) ("UK MAR").

FOR IMMEDIATE RELEASE                                                                                                                            27 May 2026

Nanoco Group PLC

("Nanoco", the "Group", or the "Company")

Intention to delist from the Main Market of the London Stock Exchange

Since the announcement on 26 January 2026 relating to the termination of the process of finding a purchaser for the Group's trading business, the Board has been considering various options to both maximise shareholder value and preserve the Company's cash balances. The Board believes that by taking further measures to reduce the Company's operating costs and carefully investing its remaining resources in existing high-potential business areas, greater value can be generated for Shareholders.

In order to further reduce operating costs, the Board has decided to seek Shareholder approval for the proposed cancellation of the Ordinary Shares from the Official List and from admission to trading on the main market for listed securities of the London Stock Exchange (the "Cancellation") while maintaining the ability for Shareholders to continue to be able to trade in Ordinary Shares through the Matched Bargain Facility described below.

Such cancellation is expected to result in a further annual cost savings of £0.7m. Although the Company had a cash balance of £10.1 million as at 19 May 2026 and the Company is neither currently experiencing any financial difficulty nor is it expected to in the near term, these cost savings will extend the Group's cash runway, with a view to being break even in the medium term. Additionally, this will also free up significant resource which can be allocated to the achievement of the Group's strategic objectives.

Conversely, were these cost savings to not be achieved, and were there further delays in the commercialisation of the Company's products, the Group's ability to break even in the medium term and achieve its strategic objectives would be further hindered by the current cost and resource burden associated with being a listed company.

Following the proposed Cancellation, it is proposed to re-register the Company as a private limited company (the "Re-registration") and to adopt new articles of association to reflect the change in the Company's status to a private limited company.

As both the Cancellation and the Registration require the approval of not less than 75 per cent. of the votes cast by Shareholders (whether present in person or by proxy) at a General Meeting, a circular (the "Circular") has today been dispatched to Shareholders containing further detail about the Cancellation and the Re-registration and convening a general meeting to be held at 10.30 a.m. on 19 June 2026 for the purposes of obtaining the necessary approvals.

Background to and reasons for the Proposals

The Board believes that there is value in the business with the potential to create further value for Shareholders. During the sale process, the Group made operational progress, including the commencement of a Joint Development Agreement with a second Asian chemical customer and a three-year extension of its Joint Development Agreement with its first Asian chemical customer.

In addition, the Group achieved a successful result in its litigation with LG Electronics Inc. in November 2025, the proceeds of which have now been received. The Group also reached a settlement with Shoei Chemical Inc. and Shoei Electronic Materials, Inc.

Having extensively evaluated the benefits and drawbacks for the Company and its shareholders in retaining its listing on the Official List and the admission to trading of the Ordinary Shares on the London Stock Exchange's Main Market for listed securities, the Board concluded that continuing its listing is not in the best interests of the Company and its shareholders for the following reasons:

1.    The estimated cost savings achievable as a result of the delisting, which are approximately £0.7m per annum.

2.    The UK public market environment for small companies remains highly challenging, characterised by persistent undervaluation and limited liquidity, particularly for Companies such as Nanoco with early-stage, pre-commercialisation technology and IP, where there is a significant key customer concentration risk.

3.    The increased corporate and strategic flexibility that a private limited company can have to make and implement strategic decisions more quickly than a company which is publicly traded.

4.    Operating as a private limited company will allow the Company to discuss a potential sale process unencumbered by the disclosure obligations and regulatory requirements of a publicly traded company on a regulated exchange

1.    Cost and regulatory burden

As at 19 May 2026, the Company had cash and cash equivalents of approximately £10.1m. In order to maximise value for Shareholders, a balance needs to be struck between reducing operating costs as much as possible and carefully investing the Company's remaining resources in existing business areas that have high potential in the medium term.

A significant reduction in the size of the Board has already been announced, with the retirement of Dr Nigel Pickett in February 2026, the resignation of Dmitry Shashkov during February 2026 and of Dr Alison Fielding and Dieter May at the end of April 2026. These measures, in addition to other cost savings, have reduced the Company's gross monthly cash operating costs to between £0.3m - £0.4m.

The costs of being a listed public company, both in terms of financial and management time, are significant. The annual financial costs are estimated to be £0.7m. The Cancellation would eliminate the annual expenditure associated with maintaining a listing on the Official List and would also enable the business to reallocate that expenditure to core business activities and free up management time to achieve its strategic objectives.

Conversely, were these cost savings to not be achieved, and were there further delays in the commercialisation of the Company's products, the Group's ability to break even in the medium term and achieve its strategic objectives would be further hindered by the current cost and resource burden associated with being a listed company.

2.    Limited liquidity and share price volatility

The Directors believe that the UK public market environment for small companies remains highly challenging, characterised by persistent undervaluation, which can be exacerbated by limited liquidity.

The impact of this is particularly notable for listed companies such as Nanoco with early-stage, pre-commercialisation technology and IP, where there is a significant key customer concentration risk. This impact has been apparent to the Board on multiple occasions in the Group's recent history, including in 2019 when a key contact with an American customer was terminated and in 2024 when a key contract with ST Microelectronics was terminated, resulting in significant share price volatility.

3.    Corporate and Strategic flexibility

The Board believes that a private limited company can make and implement strategic decisions more quickly than a company which is publicly traded. This was apparent during discussions with Samsung, LG Electronics and Shoei regarding potential IP infringements. This will also be advantageous in future business development discussions which would ultimately benefit the Company and Shareholders as a whole.

4.    Facilitation of a future sales process

The Board began the sale process with the belief that the Company would be better served being part of a larger entity. This belief still remains, and should the technology become commercialised and the Company become break even in the medium term, operating as a private limited company will allow the Company to discuss a potential sale process unencumbered by the disclosure obligations and regulatory requirements of a publicly traded company on a regulated exchange. This would ultimately be to the benefit of the Company and all Shareholders.

Process for, and principal effects of, the Cancellation

Under the UKLR, it is a requirement that the Cancellation must be approved by not less than 75 per cent. of votes cast by Shareholders at a General Meeting.

The UKLR further require any Main Market company with a listing of equity shares in the equity shares (commercial companies) category that wishes the FCA to cancel the listing of its shares on the Official List to ensure that the anticipated date of cancellation is not less than 20 business days following the passing of the Cancellation Resolution. Therefore, subject to the Cancellation Resolution being passed at the General Meeting, Cancellation will be not less than 20 Business Days following the passing of the Cancellation Resolution. Accordingly, if the Cancellation Resolution is passed, it is expected that the last day of dealings in Ordinary Shares on the Main Market will be 17 July 2026 and that the Cancellation will become effective at 8.00 a.m. on 20 July 2026.

The principal effects of the Cancellation will be that:

·     there will be no formal market mechanism enabling Shareholders to trade Ordinary Shares, no recognised market or trading facility is intended to be put in place to facilitate the trading of Ordinary Shares post Cancellation (save for the Matched Bargain Facility described in paragraph 4 below, which will provide a limited mechanism to facilitate the trading of Ordinary Shares off-market), no price will be publicly quoted for the Ordinary Shares and the transfer of Ordinary Shares will be subject to the provisions of the Articles;

·      the Ordinary Shares will remain freely transferable, it is likely that the liquidity and marketability of the Ordinary  Shares will, in the future, be more constrained than at present and the value of such shares may be adversely affected as a consequence;

·     in the absence of a formal market and quote, it may be more difficult for Shareholders to determine the market value of their investment in the Company at any given time;

·     the Company will no longer be subject to the UK MAR regulating inside information and other matters;

·     the Company will no longer be subject to the UKLR and, accordingly, Shareholders will no longer be afforded the protections given by the UKLR. In particular, the Company will not be bound to:

a.    make any public announcements of material developments, or to announce interim or final results;

b.    comply with any of the corporate governance practices applicable to Main Market companies;

c.     announce substantial transactions and related party transactions; or

d.    comply with the requirement to seek Shareholder approval for reverse takeovers and fundamental changes in the Company's business;

·     the Company will no longer be required to publicly disclose any change in major shareholdings in the Company under the Disclosure Guidance and Transparency Rules;

·     whilst the Company's CREST facility will remain in place immediately following the Cancellation, the Company's CREST facility may be cancelled in the future and, although the Ordinary Shares will remain transferable, they may cease to be transferable through CREST (in which case, Shareholders who hold Ordinary Shares in CREST will receive share certificates); and

·     the Cancellation and subsequent Re-registration may have tax consequences for Shareholders. The Company is not able to provide Shareholders with any form of tax advice, and Shareholders are strongly advised to seek their own professional advice in order to ascertain the consequences for them of continuing to hold Ordinary Shares following the Cancellation becoming effective.

The Company currently intends that it will continue to provide certain facilities, services and protections to Shareholders that they currently enjoy as shareholders of a listed company following the proposed Cancellation. It is intended that the Company will continue to:

·    communicate information about the Company (including annual accounts) to its Shareholders, as required by the Companies Act 2006;

·    for at least 12 months following the Cancellation, maintain its website, and post updates on the website at https://www.nanocotechnologies.com/from time to time, although Shareholders should be aware that there will be no obligation on the Company to include all of the information required under the Disclosure Guidance and Transparency Rules, UK MAR or to update the website as required by the UKLR; and

·    make available to Shareholders, by way of a Matched Bargain Facility, the means to buy and sell Ordinary Shares on a matched bargain basis following the Cancellation, as further set out in paragraph 4 below; however, there is no guarantee that this facility will provide liquidity in the future. JP Jenkins, the intended provider of the Matched Bargain Facility, is authorised and regulated by the FCA.

Matched Bargain Facility

The Company has made arrangements for the Matched Bargain Facility to assist Shareholders to trade in the Ordinary Shares from the date of Cancellation, if the Cancellation Resolution is passed. The Matched Bargain Facility will be provided by JP Jenkins, which is authorised and regulated by the FCA. Under the Matched Bargain Facility, Shareholders or persons wishing to acquire or dispose of Ordinary Shares will be able to leave an indication with JP Jenkins, through their stockbroker, of the number of Ordinary Shares that they are prepared to buy or sell and the price at which they are prepared to do so. In the event that JP Jenkins is able to match that order with an opposite sell or buy instruction, it would contact both parties and then effect the bargain (trade). Should the Cancellation become effective, the Matched Bargain Facility will commence, and details will be made available to Shareholders on the Company's website. It should be noted, however, that there is no guarantee as to the liquidity such a facility would afford the Ordinary Shares post Cancellation. Therefore, Shareholders should carefully consider, inter alia, the effects of the proposed Cancellation set out above and seek their own independent advice when assessing the likely impact of the Cancellation.

The Matched Bargain Facility is intended to operate for a minimum of twelve months after Cancellation. The current intention is that it will continue beyond that time, but Shareholders should note it could be withdrawn at short notice and therefore inhibit Shareholders' ability to trade the Ordinary Shares. If Shareholders wish to buy or sell Ordinary Shares on the Main Market, they must do so prior to the Cancellation becoming effective. As noted above, in the event that Shareholders approve the Cancellation, it is anticipated that the last day of dealings in Ordinary Shares on the Main Market will be 17 July 2026 and that the effective date of the Cancellation will be 8.00 a.m. on 20 July 2026.

Takeover Code

The Takeover Code applies to any company which has its registered office in the UK, the Channel Islands or the Isle of Man if any of its equity share capital or other transferable securities carrying voting rights are admitted to trading on a UK regulated market, a UK multilateral trading facility, or a stock exchange in the Channel Islands or the Isle of Man. The Takeover Code therefore currently applies to the Company as its securities are admitted to trading on the Main Market, which is a UK regulated market.

The Takeover Code also applies to any company which has its registered office in the UK, the Channel Islands or the Isle of Man if any of its securities were admitted to trading on a UK regulated market, a UK multilateral trading facility, or a stock exchange in the Channel Islands or the Isle of Man at any time during the preceding two years.

Accordingly, if the Cancellation is approved by Shareholders at the General Meeting and becomes effective, the Takeover Code will continue to apply to the Company for a period of two years after the Cancellation, following which the Takeover Code will cease to apply to the Company.

While the Takeover Code continues to apply to the Company, a mandatory cash offer will be required to be made if either:

a.    any person acquires an interest in shares which (taken together with the shares in which the person or any person acting in concert with that person is interested) carry 30 per cent. or more of the voting rights of the company; or

b.    any person, together with persons acting in concert with that person, is interested in shares which in the aggregate carry not less than 30 per cent. of the voting rights of a company but does not hold shares carrying more than 50 per cent. of such voting rights and such person, or any person acting in concert with that person, acquires an interest in any other shares which increases the percentage of shares carrying voting rights in which that person is interested.

Brief details of the Panel, and of the protections afforded by the Takeover Code, are set out in Part III of the Circular.

Before voting on the Cancellation, you may want to take independent professional advice from an appropriate independent financial adviser.

APPENDIX

The Takeover Code

The Takeover Code is issued and administered by the Panel. The Takeover Code currently applies to the Company and accordingly Shareholders are entitled to the protections afforded by the Takeover Code.

The Takeover Code and the Panel operate principally to ensure that shareholders in an offeree company are treated fairly and are not denied an opportunity to decide on the merits of a takeover and that shareholders in an offeree company of the same class are afforded equivalent treatment by an offeror. The Takeover Code also provides an orderly framework within which takeovers are conducted. In addition, it is designed to promote, in conjunction with other regulatory regimes, the integrity of the financial markets.

The Takeover Code is based upon a number of general principles (the "General Principles") which are essentially statements of standards of commercial behaviour. The General Principles apply to takeovers and other matters to which the Takeover Code applies. They are applied by the Panel in accordance with their spirit in order to achieve their underlying purpose.

In addition to the General Principles, the Takeover Code contains a series of rules (the "Rules"). Like the General Principles, the Rules are to be interpreted to achieve their underlying purpose. Therefore, their spirit must be observed as well as their letter. The Panel may derogate or grant a waiver to a person from the application of a Rule in certain circumstances.

A summary of key points regarding the application of the Takeover Code to takeovers is set out below.

Equality of treatment

General Principle 1 of the Takeover Code states that all holders of securities of an offeree company of the same class must be afforded equivalent treatment. Furthermore, Rule 16.1 requires that, except with the consent of the Panel, special arrangements may not be made with certain shareholders in the offeree company if there are favourable conditions attached which are not being extended to all shareholders.

Information to shareholders

General Principle 2 requires that the holders of the securities of an offeree company must have sufficient time and information to enable them to reach a properly informed decision on the takeover bid. Consequently, a document setting out full details of an offer must be sent to the offeree company's shareholders.

The opinion of the offeree board and independent advice

The board of the offeree company is required by Rule 3.1 to obtain competent independent advice as to whether the financial terms of any offer are fair and reasonable and the substance of such advice must be made known to its shareholders. Rule 25.2 requires the board of the offeree company to send to shareholders and persons with information rights its opinion on the offer and its reasons for forming that opinion. That opinion must include the board's views on: (i) the effects of implementation of the offer on all the company's interests, including, specifically, employment; and (ii) the offeror's strategic plans for the offeree company and their likely repercussions on employment and the locations of the offeree company's places of business.

The document sent to shareholders must also deal with other matters such as interests and recent dealings in the securities of the offeror and the offeree company by relevant parties and whether the directors of the offeree company intend to accept or reject the offer in respect of their own beneficial shareholdings.

Rule 20.1 states that, except in certain circumstances, information and opinions relating to an offer or a party to an offer must be made equally available to all offeree company shareholders and persons with information rights as nearly as possible at the same time and in the same manner.

Option holders and holders of convertible securities or subscription rights

Rule 15 provides that when an offer is made and the offeree company has convertible securities, options or subscription rights outstanding, the offeror must make an appropriate offer or proposal to the holders of those securities to ensure their interests are safeguarded.
