STRATEGIC REPORT

FOR THE YEAR ENDED 30 NOVEMBER 2025

The directors present their Strategic Report for the company for the year ended 30 November 2025.

Purolite (Int.) Ltd is part of the Ecolab Inc group of companies and the principal activity is the sale of Ion exchange resins.

The company is principally engaged in the sale of ion exchange resins and operates overseas branches in France, Italy and Spain.

Business review

Turnover has decreased from £50,753,244 in 2024 to £42,925,179 in 2025, as in 2024, the company experienced high agarose sales in Italy that were not repeated in 2025 due to the business being transferred to the UK; Italy were no longer responsible for invoicing agarose. Operating profit has decreased from £2,819,687 in 2024 to £1,552,567 in 2025. The net assets as at 30 November 2025 were £9,523,964 (2024: £8,073,812).

Performance during the year continued to be driven by focusing on strategic targets of improving our customer experience and business performance via focus on customers providing the highest standard of product, service and delivery to customers at a competitive price and continued expansion into current and new markets.

Principal risks and uncertainties

Competition:
This is a fairly small industry with several large industrial participants. Due to complexity in formulation and production, entry into ion exchange technology by new entities on a worldwide scale is difficult to achieve. Regulatory requirements pose further barriers to entry. The company maintains a vigilant monitor of competitor offerings. We ensure our presence with consistent high quality products with exceptional service.

Political:
Whilst there is always a potential of political risks this is continually managed with proactive communication with government agencies.

Financial risk management objectives and policies

The company uses financial instruments, other than derivatives, comprising borrowings, cash and other liquid resources and various other items such as trade debtors and creditors that arise directly from its operations. The main purpose of these financial instruments is to raise finance for the company’s operations. The main risks arising from the company financial instruments are interest rate risk, liquidity risk and foreign currency risk. The directors review and agree policies for managing each of these risks and they are summarized below. The policies have remained unchanged from previous periods.

Interest Rate Risk:
The company finances its operations through a mixture of retained profits and inter-company accounts. The exposure to interest rate risk is limited.

Liquidity Risk:
The company seeks to manage financial risk by ensuring sufficient liquidity is available to meet foreseeable needs and to invest cash assets safely and profitably. Primarily this is achieved through inter-company accounts or through loans arranged at group level. Short term flexibility is achieved by overdraft facilities.

STRATEGIC REPORT (CONTINUED)

FOR THE YEAR ENDED 30 NOVEMBER 2025

Financial risk management objectives and policies (continued)

Currency Risk:
The company is exposed to transaction and translation foreign exchange risk. In relation to translation risk the proportion of assets held in the foreign currency are matched to an appropriate level of borrowings in the same currency.

Credit Risk:
The company has no significant exposure of credit risk. The company has implemented policies that require appropriate credit checks on potential customers before committing to sales to those customers.

Price Risk:
The company is affected by volatility of certain chemicals purchased as raw materials for ion exchange resin manufacture. The company manages this risk by passing on increases to its customers.

This report was approved by the board and signed on its behalf.

Directors' Responsibilities Statement

The directors are responsible for preparing the Strategic Report and the Directors' Report and the financial statements in accordance with applicable law and regulations.

Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law, including FRS 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland’). Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs and profit or loss of the company for that period. In preparing these financial statements, the directors are required to:

∙select suitable accounting policies and then apply them consistently;

∙make judgements and accounting estimates that are reasonable and prudent;

∙prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the company's transactions and disclose with reasonable accuracy at any time the financial position of the company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

DIRECTORS' REPORT (CONTINUED)

FOR THE YEAR ENDED 30 NOVEMBER 2025

Qualifying third party indemnity provisions

The company has made qualifying third party indemnity provisions for the benefit of its directors which remain in force at the date of this report.

Going concern

The company continues to adopt the going concern basis in preparing its financial statements. The uncertainty as to the future impact on the company of current inflationary pressures, including wider macro-economic events, has been considered as part of the company's adoption of the going concern basis. After making enquiries, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. The ultimate parent has expressed their willingness and ability to provide the necessary financial support in an appropriate form should the need arise. Accordingly, they continue to adopt the going concern basis in preparing the annual report and accounts.

Future developments

The directors consider the results for the year to be satisfactory and expect performance to be in line or improve as new innovative products are introduced to the portfolio.

Branches outside the United Kingdom

The company has overseas branches in Italy, Spain and France.

Disclosure of information in the Strategic Report

The company has chosen to disclose information regarding the financial instrument risk management objectives and policies in the Strategic Report rather than the Directors' Report.

The directors have also chosen to disclose the information regarding the key performance indicators in the Directors' Report rather than the Strategic Report.

Subsequent events

There are no subsequent events to disclose.

Disclosure of information to auditor

The directors confirm that:

∙so far as each director is aware, there is no relevant audit information of which the company's auditor is unaware; and

∙the directors have taken all the steps that they ought to have taken as directors in order to make themselves aware of any relevant audit information and to establish that the company's auditor is aware of that information.

Auditor

The auditor, Grant Thornton UK LLP, will be proposed for reappointment in accordance with section 485 of the Companies Act 2006.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PUROLITE (INT.) LTD

Opinion

We have audited the financial statements of Purolite (Int.) Ltd (the 'company') for the year ended 30 November 2025, which comprise the Statement of Comprehensive Income, the Balance Sheet, the Statement of Changes in Equity and notes to the financial statements, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland' (United Kingdom Generally Accepted Accounting Practice).

In our opinion:

∙the financial statements give a true and fair view of the state of the company's affairs as at 30 November 2025 and of its profit for the year then ended;

∙the financial statements have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and

∙the financial statements have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the 'Auditor's responsibilities for the audit of the financial statements' section of our report. We are independent of the company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC's Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

We are responsible for concluding on the appropriateness of the directors' use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the company's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify the auditor’s opinion. Our conclusions are based on the audit evidence obtained up to the date of our report. However, future events or conditions may cause the company to cease to continue as a going concern.

In our evaluation of the directors' conclusions, we considered the inherent risks associated with the company's business model including effects arising from macro-economic uncertainties such as current inflationary pressures, we assessed and challenged the reasonableness of estimates made by the directors and the related disclosures and analysed how those risks might affect the company's financial resources or ability to continue operations over the going concern period.

Page 6

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PUROLITE (INT.) LTD (CONTINUED)

Conclusions relating to going concern (continued)

In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

Other information

The other information comprises the information included in the Annual Report and financial statements, other than the financial statements and our Auditor's Report thereon. The directors are responsible for the other information contained within the Annual Report and financial statements. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon.

Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether there is a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of the audit:

∙the information given in the Strategic Report and the Directors' Report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

∙the Strategic Report and the Directors' Report have been prepared in accordance with applicable legal requirements.

Page 7

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PUROLITE (INT.) LTD (CONTINUED)

Matter on which we are required to report under the Companies Act 2006

In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Directors' Report.

Matters on which we are required to report by exception

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:

∙adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or

∙the financial statements are not in agreement with the accounting records and returns; or

∙certain disclosures of directors' remuneration specified by law are not made; or

∙we have not received all the information and explanations we require for our audit.

Responsibilities of directors

As explained more fully in the Directors' Responsibilities Statement set out on page 3, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the company or to cease operations, or have no realistic alternative but to do so.

Page 8

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PUROLITE (INT.) LTD (CONTINUED)

Auditor's responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an Auditor's Report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists.

Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below:

∙We obtained an understanding of how the company is complying with significant legal and regulatory frameworks through inquiries of management;

∙The company is subject to many laws and regulations where the consequences of non-compliance could have a material effect on amounts or disclosures in the financial statements. We identified Financial Reporting Standard 102 and Companies Act 2006, as those most likely to have a material effect if non-compliance were to occur;

∙We communicated relevant laws and potential fraud risks to all engagement team members and remained alert to any indicators of fraud or non-compliance with laws and regulations throughout the audit;

∙We assessed the susceptibility of the company's financial statements to material misstatement, including how fraud might occur. We considered the opportunity and incentives for management to perpetrate fraud, and the potential impact on the financial statements;

∙Audit procedures performed by the engagement team included:

−identifying the significant risk of fraud within revenue recognition and undertaking substantive testing to obtain sufficient and appropriate audit evidence;

−testing journal entries, in particular journal entries relating to management estimates and entries determined to be large or relating to unusual transactions;

−and identifying and testing related party transactions;

∙These audit procedures were designed to provide reasonable assurance that the financial statements were free from fraud or error. The risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error and detecting irregularities that result from fraud is inherently more difficult than detecting those that result from error, as fraud may involve collusion, deliberate concealment, forgery or intentional misrepresentations. Also, the further removed non-compliance with laws and regulations is from events and transactions reflected in the financial statements, the less likely we would become aware of it;

Page 9

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PUROLITE (INT.) LTD (CONTINUED)

Auditor's responsibilities for the audit of the financial statements (continued)

∙The engagement partner’s assessment of the appropriateness of the collective competence and capabilities of the engagement team including consideration of the engagement team’s:

−consideration of the engagement team's understanding of, and practical experience with, audit engagements of a similar nature and complexity;

−appropriate training, knowledge of the industry in which the company operates;

−and understanding of the legal and regulatory requirements specific to the company;

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditor's Report.

Use of our report

This report is made solely to the company's members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company's members those matters we are required to state to them in an Auditor's Report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company's members as a body, for our audit work, for this report, or for the opinions we have formed.

2.Accounting policies

2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention and in accordance with Financial Reporting Standard 102, the Financial Reporting Standard applicable in the United Kingdom and the Republic of Ireland and the Companies Act 2006.

The preparation of financial statements in compliance with FRS 102 requires the use of certain critical accounting estimates. It also requires management to exercise judgement in applying the company's accounting policies (see note 3).

The company’s presentational currency is Sterling, and all values are rounded to the nearest pound (£) except otherwise stated. The company’s functional currency is Euro as this is the currency of the primary economic environment in which the entity operates. The company's presentational currency is GBP due to the company being registered in the United Kingdom.

The preparation of the financial statements requires the directors to make a number of estimates, including an assessment of the appropriateness of the going concern basis of preparation of the financial statements. This assessment includes a review of the future economic environment and the company’s future prospects and performance. Detail of the directors' considerations is included in note 2.3.

The following principal accounting policies have been applied:

2.2

2.4

Foreign currency translation

Functional and presentation currency

The company's functional currency is EUR. This differs from the presentational currency which is GBP and all values are rounded to the nearest pound (£) except where otherwise stated. The company's functional currency is EUR due to the company operating overseas branches in France, Italy and Spain. The company's presentational currency is GBP due to the company being registered in the United Kingdom.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

2.5

Turnover

Turnover comprises revenue recognised by the company in respect of goods and services supplied during the period, exclusive of Value Added Tax and trade discounts.

Revenue from the sale of goods is recognised when the significant risks and benefits of ownership of the product have transferred to the buyer, which may be upon shipment, completion of the product or the product being ready for delivery, based on specific contract terms.

2.6

Operating leases: the company as lessee

Rentals paid under operating leases are charged to the Statement of Comprehensive Income on a straight-line basis over the lease term.

2.Accounting policies (continued)

2.7

Pensions

Defined contribution pension plan

The company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the company pays fixed contributions into a separate entity. Once the contributions have been paid the company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the plan are held separately from the company in independently administered funds.

2.8

Interest income

Interest income is recognised in profit or loss using the effective interest method.

2.9

Finance costs

Finance costs are charged to the Statement of Comprehensive Income over the term of the debt using the effective interest method so that the amount charged is at a constant rate on the carrying amount. Issue costs are initially recognised as a reduction in the proceeds of the associated capital instrument.

2.10

Current and deferred taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the Balance Sheet date in the countries where the company operates and generates income.

2.11

Intangible assets

Software is capitalised at cost and is amortised on a straight line basis over its estimated useful economic life of 5 years.

Amortisation charged in the period is included in administrative expenses in the Statement of Comprehensive Income.

2.12

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Page 16


PUROLITE (INT.) LTD

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEAR ENDED 30 NOVEMBER 2025

2.Accounting policies (continued)

2.12

Tangible fixed assets (continued)

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives.

Depreciation is provided on the following basis:

Fixtures & fittings

20% straight line.

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in the Statement of Comprehensive Income.

2.13

Stocks

Stocks are stated at the lower of cost and net realisable value, being the estimated selling price less costs to complete and sell. Cost is based on the cost of purchase on a first in, first out basis. Work in progress and finished goods include labour and attributable overheads.

At each Balance Sheet date, stocks are assessed for impairment. If stock is impaired, the carrying amount is reduced to its selling price less costs to complete and sell. The impairment loss is recognised immediately in profit or loss.

2.14

Cash

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours.

2.15

Financial instruments

The company has elected to apply the provisions of Section 11 “Basic Financial Instruments” of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the company's Balance Sheet when the company becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

Basic financial assets

Basic financial assets, which include trade and other debtors, cash and bank balances, are initially measured at their transaction price (adjusted for transaction costs except in the initial measurement of financial assets that are subsequently measured at fair value through profit and loss) and are subsequently carried at their amortised cost using the effective interest method, less any provision for impairment, unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest.

Discounting is omitted where the effect of discounting is immaterial. The company's cash and cash equivalents, trade and most other debtors due within the operating cycle fall into this category of financial instruments.

Impairment of financial assets

At the end of each reporting period financial assets measured at amortised cost are assessed for objective evidence of impairment. If an asset is impaired the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.

Financial assets are impaired when events, subsequent to their initial recognition, indicate the estimated future cash flows derived from the financial asset(s) have been adversely impacted. The impairment loss will be the difference between the current carrying amount and the present value of the future cash flows at the asset(s) original effective interest rate.

If there is a favourable change in relation to the events surrounding the impairment loss then the impairment can be reviewed for possible reversal. The reversal will not cause the current carrying amount to exceed the original carrying amount had the impairment not been recognised. The impairment reversal is recognised in the profit or loss.

Basic financial liabilities

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instrument is any contract that evidences a residual interest in the assets of the company after the deduction of all its liabilities.

Basic financial liabilities, which include trade and other creditors, bank loans and other loans are initially measured at their transaction price (adjusting for transaction costs except in the initial measurement of financial liabilities that are subsequently measured at fair value through profit and loss). When this constitutes a financing transaction, whereby the debt instrument is measured at the present value of the future payments discounted at a market rate of interest, discounting is omitted where the effect of discounting is immaterial.

Debt instruments are subsequently carried at their amortised cost using the effective interest rate method.

Trade creditors are obligations to pay for goods and services that have been acquired in the ordinary course of business from suppliers. Trade creditors are classified as current liabilities if the payment is due within one year. If not, they represent non-current liabilities. Trade creditors are initially recognised at their transaction price and subsequently are measured at amortised cost using the effective interest method. Discounting is omitted where the effect of discounting is immaterial.

2.Accounting policies (continued)

2.15

Financial instruments (continued)

Derecognition of financial assets

Financial assets are derecognised when their contractual right to future cash flow expire, or are settled, or when the company transfers the asset and substantially all the risks and rewards of ownership to another party. If significant risks and rewards of ownership are retained after the transfer to another party, then the company will continue to recognise the value of the portion of the risks and rewards retained.

Derecognition of financial liabilities

Financial liabilities are derecognised when the company's contractual obligations expire or are discharged or cancelled.

3.	Judgements in applying accounting policies and key sources of estimation uncertainty

The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Estimates are based on historical experience and other assumptions that are considered reasonable in the circumstances. The actual amount or values may vary in certain instances from the assumptions and estimates made. Changes will be recorded, with corresponding effect in the financial statements, when, and if, better information is obtained.

Critical judgements and sources of estimation uncertainty that management have made in the process of applying accounting policies disclosed herein and that have a significant effect on the amounts recognised in the financial statements relate to the following:

Estimates

Provisions (see notes 13 & 14)
A provision has been made for trade debtors and stock. The provisions are estimates of balances that may not be collected/recovered. The actual costs and timing of future cash flows are dependent on future events. The difference between expectations and the actual future liability will be accounted for in the period when such determination is made.

Judgements

In the process of preparing the financial statements, no significant judgements were applied.

Turnover

The whole of the turnover is attributable to the principal activity of the company.

The analysis of sales by geographical market has not been disclosed as, in the opinion of the directors, the disclosure of this information would be seriously prejudicial to the interests of the company.
