Impax Environmental Markets PLC

Result of Exit Tender Offer Elections

Impax Environmental Markets PLC (the Company) announces the results of the Exit Tender Offer which enabled Eligible Shareholders to tender up to 100 per cent. of their Shares, as set out in the Exit Tender Offer circular published on 17 March 2026 (the Circular). The Exit Tender Offer was approved by Shareholders at a general meeting of the Company held on 16 April 2026 and Exit Tender Offer elections closed at 1.00 p.m. on 17 April 2026.

A total of 148,202,139 Shares were validly tendered pursuant to the Exit Tender Offer, representing 77.83 per cent. of the Shares in issue as at 17 April 2026 (excluding Shares held in treasury). Whilst Saba Capital LLP (Saba) declined to confirm its tender elections to the Board, it appears from an analysis of the elections that Saba has elected to tender the majority, if not all, of its position. Once the assets allocated to the Tender Pool have been realised and the Tender Exit Shares have been repurchased the Board will review options for the Company's future, bearing in mind the post-Exit Tender Offer size of the Company and the confirmed composition of its share register going forwards.

In accordance with the terms of the Exit Tender Offer, the Company's assets and liabilities will, following valuation on the Calculation Date (being close of business on 29 April 2026), be allocated between the Continuing Pool and the Tender Pool on the basis set out in the Circular.

Following the allocation of assets and liabilities to the Continuing Pool and the Tender Pool the assets in the Tender Pool will be realised. The Tender Pool will bear all costs associated with the realisation of the assets within the Tender Pool and the Tender Pool Costs (as set out in the Circular). The Tender Pool will bear its share of the operating costs of the Company between the Calculation Date and the Tender Pool Determination Date (defined below). These operating costs will be borne on a pro rata basis between the Tender Pool and the Continuing Pool.

Following the date upon which all of the assets contained in the Tender Pool have been realised, and all liabilities to be borne by the Tender Pool (other than Tender Pool Costs) met, the Directors will select a date upon which the Tender Pool Final Asset Value will be calculated (the Tender Pool Determination Date). The Tender Pool Final Asset Value will equal the value of the assets in the Tender Pool on the Tender Pool Determination Date, less the Tender Pool Costs.

The Tender Price, which is expected to be announced before the end of May, will be an amount equal to the Tender Pool Final Asset Value divided by the total number of successfully tendered Shares, in each case on the Tender Pool Determination Date.

As set out in the Circular, the Company has very substantial distributable reserves. As the final amount to be returned to Shareholders via the repurchase of the Tender Exit Shares will be based on the Tender Pool Final Asset Value as at the Tender Pool Determination Date, it is not possible to say definitively whether the Company will have sufficient distributable reserves. However, based on the distributable reserves as at 17 April 2026, it is likely that all of the Shares in respect of which a valid election was made will be accepted as Tender Exit Shares.

Confirmation of this, or any modest amount of scale back required as a result of distributable reserves, along with confirmation of the Tender Price will be announced in due course.

The Circular is available for viewing at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism. Terms used but not defined in this announcement shall have the meanings given to them in the Circular.

Glen Suarez, Chairman of the Company commented:

"Elections for the Exit Tender Offer have now closed, and our analysis leads us to conclude that Saba has tendered the majority of its position.

"There are no winners here. This was an extraordinarily difficult situation to navigate, trying to balance the varied desires of all of our different shareholders. The overwhelming majority of shareholders voted just a year ago in favour of IEM's continuation, but Saba made it clear in subsequent interactions with the Chair that they did not agree. As a result, the Board acted proactively to offer an exit to all shareholders who wished to take it.

"The Board will now carefully consider all available options regarding the Company's future, and will provide a further update with the Notice of AGM, to be announced shortly."

Notice for U.S. Shareholders

The Exit Tender Offer relates to securities in a non-U.S. company registered in England and Wales with a listing on the London Stock Exchange and is subject to the disclosure and procedural requirements, rules and practices applicable to companies listed in the United Kingdom, including with respect to the Exit Tender Offer timetable, settlement procedures, withdrawal, waiver of conditions and timing of payments, which differ from those of the United States in certain material respects.

This document has been prepared in accordance with UK style and practice for the purpose of complying with the laws of England and Wales, the UK Listing Rules and the rules of the London Stock Exchange. U.S. Shareholders should read this entire document. Any financial information relating to the Company has been prepared in accordance with UK GAAP (including FRS 102 and SORP), but has not been prepared in accordance with generally accepted accounting principles in the United States; thus it may not be comparable to financial information relating to U.S. companies. The Exit Tender Offer was made in the United States pursuant to Section 14(e) of, and Regulation 14E under the Exchange Act, subject to the exemptions provided by Rule 14d-1(d) thereunder and otherwise in accordance with the requirements of the UK Listing Rules of the Financial Conduct Authority. Accordingly, the Exit Tender Offer is subject to disclosure and other procedural requirements that are different from those applicable under U.S. domestic tender offer procedures. U.S. Shareholders should note that the Company is not listed on a U.S. securities exchange, subject to the periodic reporting requirements of the Exchange Act or required to, and does not, file any reports with the SEC thereunder. The Exit Tender Offer was made to U.S. Shareholders on the terms and conditions that are no less favourable than as those made to all other Shareholders whom an offer is made and any informational documents are disseminated to U.S. Shareholders on a basis comparable to the method that such documents are provided to other Shareholders, subject to applicable law and regulatory requirements.

It may be difficult for U.S. Shareholders to enforce certain rights and claims arising in connection with the Exit Tender Offer under U.S. federal securities laws since the Company is located outside the United States and its officers and Directors reside outside the United States. It may not be possible to sue a non-U.S. company or its officers or Directors in a non-U.S. court for violations of U.S. securities laws. It also may not be possible to compel a non-U.S. company or its affiliates to subject themselves to a U.S. court's judgment. Judgments of U.S. courts are generally not enforceable in the UK. In addition, original actions, or actions for the enforcement of judgments of U.S. courts, based on the civil liability provisions of the U.S. federal securities laws, may not be enforceable in the UK.

To the extent permitted by applicable law and in accordance with regulations, the Company, Winterflood, or any of their affiliates may from time to time, directly or indirectly, make certain purchases of, or arrangements to purchase, Shares outside the United States during the period in which the Exit Tender Offer remains open for acceptance, including sales and purchases of Shares effected by Winterflood acting as market maker in the Shares. These purchases, or other arrangements, may occur either in the open market at prevailing prices or in private transactions at negotiated prices. To the extent permitted by applicable law and regulations, and subject to compliance with the conditions of Rule 14e-5 and any available exemption thereunder (including, Rule 14e-5(b)(12), such purchases, or arrangements to purchase, will be effected outside the United States and made in compliance with applicable UK law and regulation, including the UK Listing Rules. Any information about such purchases will be disclosed as required in the United Kingdom and the United States and, if required, will be reported via the Regulatory Information Service of the London Stock Exchange. To the extent that such information is made public in the United Kingdom, this information will also be publicly available to Shareholders in the United States.

Neither the SEC nor any U.S. state securities commission has approved or disapproved of this transaction or passed upon the merits or fairness of such transaction or passed upon the adequacy of the information contained in this announcement. Any representation to the contrary is a criminal offence.

For the purposes of this announcement, the "United States", "United States of America", "U.S." and "US" means the United States of America, its territories and possessions (including Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, Wake Island and the Northern Mariana Islands), any state of the United States of America and the District of Columbia.
