THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) TRUSTEES’ REPORT FOR THE YEAR ENDED 30 SEPTEMBER 2025

The Board of Trustees (being the directors of The Weizmann Institute Foundation - known as Weizmann UK), presents its report and audited financial statements for the year ended 30 September 2025. The report and the financial statements have been produced in accordance with the provisions of the FRS 102 SORP – Accounting and Reporting by Charities – Second Edition, effective 1 January 2019, the Companies Act 2006, and the Charities Act 2011.

SUMMARY OF THE YEAR

The year under review, was conducted against the backdrop of the ongoing conflict in Israel, which presented significant operational and strategic challenges for Weizmann UK and for its principal beneficiary, the Weizmann Institute of Science. These challenges were particularly acute during the escalation of hostilities between Iran and Israel in June 2025. On 15 June 2025, two missiles struck the Weizmann Institute campus, resulting in significant destruction. Fifty-two research laboratories, primarily in the life sciences, cancer research and environmental fields, were destroyed, and over 100 buildings were damaged. Five buildings, including two that were directly hit, were rendered inoperable. In response, and in line with its regulatory obligations, Weizmann UK submitted a Serious Incident Report to the Charity Commission.

The Weizmann Institute acted swiftly to stabilise operations, and Weizmann UK supported this response through its Emergency and Recovery Fund Appeal. As a result of the appeal, income increased significantly during the year, reflecting the charity’s active role in supporting recovery efforts. The appeal attracted substantial and very generous donor support, which raised over $40million or £29.4million. In parallel, Weizmann UK continued to deliver a programme of events and to promote scientific collaboration between the Weizmann Institute and the UK. While the challenging circumstances limited opportunities for formal educational outreach programmes during the year, Weizmann UK continued to promote public engagement with science.

ACTIVITIES & ACHIEVEMENTS IN DETAIL

In the year ended 30 September 2025 the charity received donations and legacies of £34,819,463 (2024: £1,485,038) and awarded grants totaling £3,504,992 (2024: £2,748,536) to the Institute.

EDUCATION & AWARENESS

The Institute engaged its international supporters throughout the year through a series of online events, ensuring they remained informed about developments on campus as well as research breakthroughs. Weizmann UK delivered a programme of in-person lectures in London. In October 2024, Prof. Roee Ozeri presented Our Quantum Future . This was followed in December by the Annual Lecture delivered by Prof. Tamir Klein, The Wonders of the Weizmann Tree Lab , which explored the role of trees in driving climate resilience. In May 2025, cancer researcher Prof. Ruth Scherz-Shouval presented her work on the tumour microenvironment and highlighted the Weizmann Institute’s initiatives to support women in science.

Educational engagement continued through the UK Safe-Cracking Physics Tournament for Year 12 students, which took place in February 2025 at Dulwich College. Winning teams participated in the Davidson Institute’s International Safe-Cracking Competition, held virtually in April 2025. Unfortunately, despite the successful recruitment of UK students, the Bessie Lawrence International Summer Science Institute was cancelled following the missile strike in June 2025.

SCIENTIFIC COLLABORATION

The Making Connections programme, which fosters collaboration between scientists in the UK and the Weizmann Institute, continued to support ongoing research projects during the year, although no new grants were awarded. Since its inception in 2008, the programme has initiated and funded nearly 80 collaborative research projects, involving scientists from the Weizmann Institute and more than 25 UK universities and research institutes.

To evaluate its impact and inform future development, an independent external review of the programme was completed in July 2025. The Trustees, in consultation with the Weizmann Institute, are now considering the findings of this evaluation to develop a strategic approach to sustaining and enhancing this important collaborative initiative.

FUNDRAISING

Weizmann UK carries out fundraising activities to support its education and awareness-raising initiatives in the UK, as well as scientific research and educational projects at the Weizmann Institute and the Davidson Institute of Science Education in Israel. Registered with the Fundraising Regulator, Weizmann UK adheres to the Fundraising Code of Practice, ensuring that all activities are conducted legally, openly, honestly, and respectfully. No complaints were received during the year.

The Charity’s fundraising strategy focuses on engaging major individual donors who have established relationships with the Charity and its Trustees. Income is generated through new and existing supporters via special events, legacy gifts, and a major gifts programme. Additionally, online donations are encouraged through the Weizmann UK website and promotional communications. Weizmann UK does not engage third-party fundraising organisations.

In May 2025, the Weizmann Institute launched its first ever Global Fundraising Campaign Empower Tomorrow, and Weizmann UK worked closely with the Institute and its International Committees participating in fundraising events in Monaco, Switzerland and America as well as in Israel.

This year, the charity’s fundraising efforts placed a particular emphasis on supporting the Institute’s Emergency and Recovery Fund and on supporting its Women in Science programme.

COMMUNICATIONS

Weizmann UK’s donor relations and communication activities comply fully with the Data Protection Act 2018, General Data Protection Regulations (GDPR), and the Privacy and Electronic Communications Regulations (PECR). Communications are delivered via mail, email, social media, and advertising, with consent obtained and recorded where required. All supporter information is securely stored, and rights are clearly outlined in the Privacy Policy, which is readily available. Supporters can update their communication preferences at any time. All policies are reviewed annually, with oversight provided by the Risk Committee, which reports to the Board of Trustees.

No GDPR complaints or safeguarding issues were reported during the year. Weizmann UK has robust procedures in place to manage complaints and issues in line with Charity Commission guidance and regulations. The Risk Sub-Committee confirmed that the Charity’s risk controls and monitoring responsibilities are appropriate and effectively implemented.

Supporter engagement involved regular eNewsletters, magazine mailings, and social media updates throughout the year.

LOOKING AHEAD

In the coming year, Weizmann UK will focus on connecting more supporters with the Weizmann Institute’s groundbreaking research.

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) TRUSTEES’ REPORT FOR THE YEAR ENDED 30 SEPTEMBER 2025

STRUCTURE, ORGANISATION, GOVERNANCE & LEGAL STRUCTURE

Weizmann UK (its registered corporate name being The Weizmann Institute Foundation) is a company limited by guarantee (registration number 483123), which was incorporated on 8 June 1950. It operates under the name of Weizmann UK. Its constitution and principal regulations are set out in its Memorandum and Articles of Association. Weizmann UK is a registered charity (registration number 232666). The registered office is 9 Hampstead Gate, 1a Frognal, London NW3 6AL.

Weizmann UK’s charitable objectives include providing financial and material assistance, encouragement and support to and for pure and applied scientific research and related activities at the Weizmann Institute of Science.

MISSION

Weizmann UK’s mission is to raise funds for, and awareness of, the pioneering research of the Weizmann Institute of Science; nurture the next generation of leading scientists; and promote collaboration between the Institute’s scientists and those at scientific institutions in the UK.

Weizmann UK delivers public benefit in the UK through its events and education programmes; and globally by funding and promoting science for the benefit of humanity.

GOVERNANCE AND MANAGEMENT

All members of the Board of Trustees are directors of Weizmann UK. No director had any material interest in any contract or arrangement with Weizmann UK during the year with the exception of those disclosed in note 16.

The Board of Trustees is responsible for the activities of Weizmann UK. The Executive Director directs the day-to-day operation of the organisation.

At every Annual General Meeting, Trustees subject to retirement by rotation (after serving a term of not more than four years) retire from office and may offer themselves for re-election in accordance with the Articles of Association. New Trustees are appointed by the Board of Trustees. During the year, the Articles of Association were amended to remove the previous maximum limit on consecutive years of trustee service, where continued service is in the best interests of the charity and subject to appropriate assessment of individual skills and experience. An additional amendment enables the removal of a trustee by an 80% majority of the Board.

All Trustees are members of the Company for Companies Act purposes and have a maximum liability of £10.

During the year, the Board established a Grant Governance Committee as a sub-committee of the Board. The Committee provides oversight of all grants made by Weizmann UK to the Weizmann Institute of Science and to partner or collaborative institutions in the UK, ensuring compliance with legal and regulatory requirements, alignment with the charity’s purposes, and appropriate due diligence, risk assessment, monitoring and reporting. The Committee makes recommendations to the Board, with final decisions remaining reserved to the Board.

POLICY & PROCEDURES

Pay policy for senior staff:

The Remuneration Committee, Chaired by Dean Lush with David Marks, Jonathan Kropman and with Dr. Arabella Duffield as an ex officio member, meet as required to oversee the pay policy for the organisation. The pay of staff is generally reviewed annually in accordance with performance and relevant benchmarks.

The Trustees consider the Board of Trustees and senior management comprise the key management personnel of the charity in charge of directing and controlling, running and operating the Charity on a day ‐ to ‐ day basis. All Trustees give of their time freely and no Trustee received remuneration in the year. Details of Trustees’ expenses and related party transactions are disclosed in Note 4 and related party transactions are included in Note 16 to the accounts.

PUBLIC BENEFIT

The Trustees confirm that they have complied with the duty in Section 17 of the Charities Act 2011 to have due regard to the Charity Commission’s general guidance on public benefit.

FINANCIAL REVIEW

Total funds have increased from £39,056,391 to £71,292,937 largely as a result of the restricted donations of £33,373,867 received into the Emergency & Recovery Fund. The financial statements for the year ended 30 September 2025 show net income for the year before foreign exchange gains and investment gains of £30,864,006 (2024: £1,972,230 net expenditure). The net movement in funds for the year amounted to an increase of £32,236,546 (2024: decrease of £865,809) after accounting for net investment and exchange gains of £1,372,540 (2024: £1,106,421). A transfer of £1,154,470 was made from Endowed funds to Restricted funds representing the allocation of total return in the year. During the year grants of £3,574,048 (2024: £2,803,576) were awarded of which £3,504,992 (2024: £2,748,536) were made to the Weizmann Institute.

Reserves

At 30 September 2025 the Charity held unrestricted reserves of £6,897,536 (2024: £5,629,795). Included within unrestricted reserves is £69,959 (2024: £69,959) as a designated fund called Making Connections which promotes collaboration on projects undertaken between leading scientists at UK universities and scientists at the Weizmann Institute of Science.

The Trustees determined that the remaining unrestricted reserves be used as needed to fund the cost of the operations and to continue the Making Connections programme into the foreseeable future. The unrestricted reserves have also been used to fund fixed assets of £790,820 (2024: £791,572). The policy on the level of a desirable level of unrestricted reserves is reviewed periodically by the Trustees.

Grants for Scientific Research

Weizmann UK makes grants to the Weizmann Institute based on the current needs of the Institute together with the availability of funds and the requests of donors.

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) TRUSTEES’ REPORT FOR THE YEAR ENDED 30 SEPTEMBER 2025

Investment Policy

All investments held by Weizmann UK have been acquired in accordance with the powers available to the Board of Trustees and there are no specific restrictions on the investment powers available to the Board. The Board of Trustees has delegated investment monitoring responsibility to a sub-committee (the Investment Committee) whose members are: Denis Raeburn (Chair), Jonathan Kropman, Denitza Roussinova and Charles Wolfson Townsley.

Weizmann UK’s investments are allocated between a portfolio invested in Weizmann Global Endowment Management Trust (W-GEM) and a portfolio invested by Rothschild & Co. Wealth Management (UK) Limited.

Weizmann UK Trustee Martin Paisner CBE is a Trustee of W-GEM and Weizmann UK Trustee Denis Raeburn is a member of the W-GEM Oversight Board. Denis Raeburn was re-appointed as a member of the W-GEM Oversight Board for two years until 31 December 2026.

W-GEM’s stated performance objectives are several: to achieve a return which exceeds the Weizmann Institute’s spending rate and preserves the purchasing power of the assets; to outperform the MSCI All Country World Index during down markets; to produce, over time, lessvolatile returns than the MSCI All Country World Index; to perform well in comparison with two benchmarks: the Policy benchmark, weighted by asset class and over a market cycle, and peers.

The 12 months ending 30 September 2025 were a strong period for equity markets. The MSCI World Index generated positive returns in all four quarters, delivering a total return of +17.3% in USD terms over the financial year. Meanwhile, US Government Bonds also showed positive performance, with a return of +3.5% over the same 12-month period.

W-GEM, which has been allocated the bulk of Weizmann UK’s investment portfolio (approximately $33.2m or £24.7m) has been invested across a well-diversified range of asset classes and managers. Performance over the reporting period was slightly ahead of the mandate’s reference index. The W-GEM portfolio delivered a return of +12.4% for the year ended 30 September 2025, in USD, which is the reference currency of the portfolio. W-GEM’s policy benchmark is 80% MSCI All Country World Index, 10% U.S. Government Bond Index, and 10% European Government Bond Index. This benchmark returned +12.3% for the year.

It is not unexpected that W-GEM may underperform its policy benchmark over short time periods and therefore the slight underperformance over the last 12 months is not concerning in itself. In sterling terms, Weizmann UK’s investment in W-GEM saw a slight negative impact due to the modest depreciation of USD against sterling, shifting from 1.3375 to 1.3446 over the 12-month period.

The Board of Trustees has also resolved that the part of Weizmann UK’s non-endowed funds (approximately £7.4m) with both unrestricted and restricted purposes should continue to be invested in the UK by Rothschild & Co, on an unconstrained basis.

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) TRUSTEES’ REPORT FOR THE YEAR ENDED 30 SEPTEMBER 2025

The Investment Committee established what it regards as a prudent investment strategy with Rothschild & Co, which has invested in a diversified range of asset classes and securities. The report produced by Rothschild & Co indicates that Weizmann UK’s portfolio which is invested in the New Court fund increased by +5.2% in Sterling terms for the year ended 30 September 2025. The return objective of the portfolio is UK CPI +3% which, over the same period, was up +6.8%. While the portfolio did not meet its stated investment objective over the reporting period, over the long term, the fund is intended to preserve and grow the real value of the invested capital, whilst providing some protection during difficult market conditions.

Weizmann UK has Charity Commission approval to use of total return investment powers in relation to its permanent endowment investments by an order granted on 30 March 2006, as varied by a further order made on 15 August 2006. The power permits the Trustees to invest the portfolio to maximise total return and to apply an appropriate portion of the unapplied total return to income each year. Until the power is exercised to transfer a portion of unapplied total return to income (as disclosed in the fund transfers, note 11), the unapplied total return remains invested as part of the permanent endowment. This year, £1,154,470 was applied to income.

The investment property is stated at open market value and is subject to a formal revaluation every five years. A desktop valuation carried out by an independent qualified surveyor in November 2022 valued the property at £770,000. A further valuation conducted by an independent surveyor in October 2025 revalued the property at £727,000, which has been reflected in the accounts.

Currencies

The funds invested in W-GEM are denominated in US Dollars. The UK portfolio, managed by Rothschild & Co Wealth Management (UK) Limited, is denominated in UK Sterling. The Board of Trustees believes that this provides Weizmann UK with an appropriate balance of currencies.

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) TRUSTEES’ REPORT FOR THE YEAR ENDED 30 SEPTEMBER 2025

Risk Policy

The Risk Committee is appointed by the Board of Trustees. The function is to carry out assessment and analysis of risks attached to the operations of the Charity. The Risk Committee comprises the Honorary Secretary (Chair) and the Honorary Treasurer, with the Chair of the Trustees (ex officio) and is also attended by the Director of Operations and the Executive Director. In the financial year to 30 September 2025, the Risk Committee periodically considered relevant risk issues pertaining to the organisation.

These included risks as a charity supporting a cause in Israel. It was recognised that political issues in and around Israel have long been monitored as a risk, but the Committee noted the changing (and potentially increasingly negative) views relating to Israel and the implications this could have on fundraising. As the focus of Weizmann UK’s fundraising and communications is on science which has a global impact, and not on political issues relating to Israel, Weizmann UK would hope to avoid any controversy and impact on fundraising income.

In the course of the year, the Risk Committee carried out assessments key risk areas, including:

The Risk Committee recommended various steps be taken to address, monitor and ensure these are kept current and appropriate as circumstances evolve. In particular, these areas of risk are monitored by the Executive Director and continue to be brought to the attention of the Board of Trustees as appropriate and at least annually.

The Board reviewed the Risk Matrix Analysis and on review considered that the major risks to which the Charity is exposed have been analysed and acted upon and it also considered the steps taken and systems proposed to mitigate continuing risk.

The Executive Director, Director of Operations, Chair and Chair of the Risk Committee continue to monitor risk on all levels including security.

Statement of Trustees' responsibilities

The Trustees are responsible for preparing the Trustees’ Annual Report and the financial statements in accordance with applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice).

11

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) TRUSTEES’ REPORT FOR THE YEAR ENDED 30 SEPTEMBER 2025

Company law requires the Trustees to prepare financial statements for each financial year which give a true and fair view of the state of affairs of the charitable company and the group and of the incoming resources and application of resources, including the income and expenditure, of the charitable company for that period. In preparing these financial statements, the Trustees are required to:

The Trustees are responsible for keeping proper accounting records that disclose with reasonable accuracy at any time the financial position of the charitable 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 charitable company and the group and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

In so far as the Trustees are aware:

The Trustees are responsible for the maintenance and integrity of the corporate and financial information included on the charitable company’s website. The work carried out by the auditors does not involve consideration of these matters and, accordingly, the auditors accept no responsibility for any changes that may have occurred to the financial statements since they were initially presented on the website. Legislation in the United Kingdom governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

By order of the Board of Trustees on 1 May 2026

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee)

Independent Auditors’ Report to the members of the Weizmann Institute Foundation (Weizmann UK)

Opinion

We have audited the financial statements of The Weizmann Institute Foundation for the year ended 30 September 2025 which comprise the Statement of Financial Activities, the Summary Income and Expenditure Account, the Statement of Total Recognised Gains and Losses, the Balance Sheet, the Cash Flow Statement 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:

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 charitable 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

In auditing the financial statements, we have concluded that the trustees’ 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 charitable 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 trustees with respect to going concern are described in the relevant sections of this report.

Other information

The trustees are responsible for the other information. The other information comprises the information included in the Trustees’ Annual Report. 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.

13

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee)

Independent Auditors’ Report to the members of the Weizmann Institute Foundation (Weizmann UK)

In connection with our audit of the financial statements, 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 or a material misstatement of the other information. 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:

Matters on which we are required to report by exception

In the light of the knowledge and understanding of the charitable company and its environment obtained in the course of the audit, we have not identified material misstatements in the Trustees’ Annual Report (which incorporates the directors’ report).

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:

Responsibilities of trustees for the financial statements

As explained more fully in the trustees’ responsibilities statement set out on page 12, the trustees (who are also the directors of the charitable company for the purposes of company law) 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 trustees 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 trustees are responsible for assessing the charitable 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 trustees either intend to liquidate the charitable company or to cease operations, or have no realistic alternative but to do so.

14

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) Independent Auditors’ Report to the members of the Weizmann Institute Foundation (Weizmann UK)

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. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

Based on our understanding of the charitable company and the environment in which it operates, we identified that the principal risks of non-compliance with laws and regulations related to health and safety requirements, GDPR, employment law, company and charity law and we considered the extent to which non-compliance might have a material effect on the financial statements. We also considered those laws and regulations that have a direct impact on the preparation of the financial statements such as the Charities Act 2011 and Companies Act 2006 and consider other factors such as payroll tax.

We evaluated management’s incentives and opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls), and determined that the principal risks were related to the improper recognition of revenue and management bias in accounting estimates. Audit procedures performed by the engagement team included:

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation.

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025

1. Accounting policies

The financial statements have been prepared in accordance with Accounting and Reporting by Charities: Statement of Recommended Practice applicable to charities preparing their accounts in accordance with the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) (effective 1 January 2019) - (the Statement of Recommended Practice for Charities (SORP 2015) (Second Edition, effective 1 January 2019)), the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) and the Companies Act 2006. Weizmann UK meets the definition of a public benefit entity under FRS 102. Assets and liabilities are initially recognised at historical cost or transaction value unless otherwise stated in the relevant accounting policy note(s).

The trustees have assessed whether the use of the going concern basis is appropriate and have considered possible events or conditions that might cast significant doubt on the ability of the charity to continue as a going concern. The trustees have made this assessment for a period of at least one year from the date of approval of the financial statements. In particular the trustees have considered the charity’s forecasts and projections and have taken account of pressures on donation and investment income. After making enquiries the trustees have concluded that there is a reasonable expectation that the charity has adequate resources to continue in operational existence for the foreseeable future. The charity therefore continues to adopt the going concern basis in preparing its financial statements.

Investments in common stocks and fixed income securities are stated at fair value as at the balance sheet date. Fair value of exchange-listed securities is determined by the last sale price on the valuation date. Fixed income securities are valued based on prices obtained by one or more independent pricing services. Mutual funds are valued based on published net asset value.

The Weizmann Global Endowment Fund (“WGEF”) is a limited partnership based in the USA which invests in a diverse range of equities and bonds and is managed by Weizmann Global Endowment Management Trust (W-GEM). WGEF’s investments in nonregistered investment companies, which represent circa two thirds of its net assets, are carried at fair value as determined by the general partner and generally represent the Fund’s pro rata interest in the net assets of each nonregistered investment company. All valuations utilise financial information supplied by each investment company.

The statement of financial activities includes the net gains and losses arising on the revaluation and disposals throughout the year. Investments are stated at fair value. It is the Weizmann UK’s policy to keep valuations up to date such that when investments are sold there is no gain or loss arising. As a result the Statement of Financial Activities (“SOFA”) only includes those unrealised gains and losses arising from the revaluation of the investment portfolio throughout the year. Disclosure is made in note 6 of the difference between the historical cost and the sale proceeds of the investments sold during the year. Investment income is included on an accruals basis and is allocated across funds in proportion to the value of funds held.

21

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025

1. Accounting policies (continued)

(b) Investments (continued)

The Charity Commission permitted Weizmann UK to adopt the use of total return investment powers in relation to its permanent endowment investments by an order granted on 15 August 2006. The power permits the trustees to invest the portfolio to maximise total return and to apply an appropriate portion of the unapplied total return to income each year. In the current year 4.5% has been applied to income. A rate of 4.5% has been applied to new endowment investments made during the year. Until the power is exercised to transfer a portion of unapplied total return to income (as disclosed in the fund transfers, note 11) the unapplied total return remains invested as part of the Permanent Endowment.

Properties not used for charitable purposes are classified as investment properties and are included in investments at open market value. Investment properties are formally revalued every five years.

Tangible fixed assets are stated at historic purchase cost less accumulated depreciation. Tangible fixed assets with a value of £1,000 or more are capitalised.

Depreciation is provided to write off the cost, less estimated residual values, of all fixed assets, evenly over their expected useful lives. It is calculated at the following rates:

Furniture & fixtures - 4 years Office equipment - 3 years Website - 3 years Property - 50 years

(d) Foreign currency translation

The market value of investments outside the United Kingdom and monetary assets denominated in a foreign currency are translated into sterling at the rate of exchange ruling at the balance sheet date.

Revenue and expenses in foreign currencies are recorded in sterling based on monthly average exchange rates. All gains or losses arising on translation are included in the SOFA for the year.

The financial statements are prepared on the accruals basis, with the exception of certain income, which cannot be quantified until it is received. The policies applied are:

Donations and Legacy income is included in the SOFA when Weizmann UK is legally entitled to the income (probate has been granted, or a donation received) and the amount can be quantified with reasonable accuracy.

Pledged donations are accounted for as and when entitlement arises, the amount can be reliably quantified and the economic benefit to the charity is considered probable.

22

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025

1. Accounting policies (continued)

Event income (including donations received at events) and expenditure is included in the SOFA in the period in which the event takes place. Income received in advance is deferred to future periods.

Cost of raising funds are those costs incurred in attracting donations and legacies. Investment Management fees and other overheads are allocated between restricted, unrestricted and endowed funds on appropriate bases such as investment values and staff time.

Governance costs comprise all costs involving the public accountability of the charity and its compliance with regulation and good practice. These costs include costs related to statutory audit and legal fees together with an apportionment of overhead and support costs.

Overhead and support costs have been allocated first between Charitable Activity and governance. Overhead and support costs relating to Charitable Activities have been apportioned based on the number of individual grant awards made in recognition that the administrative costs of awarding, monitoring and assessing research grants, salary support and postgraduate scholarships are broadly equivalent.

The allocation of overhead and support costs is analysed in note 3. All Value Added Tax (VAT) costs are irrecoverable and included within the cost expenditure category to which they relate.

Weizmann UK makes grants to the Institute based on the current needs of the Institute together with the availability of funds and the requests of donors.

(f) Funds

These financial statements include the income and expenditure of all endowment, restricted and unrestricted funds of Weizmann UK.

Unrestricted funds comprise those funds, which the Board of Trustees are free to use in accordance with the charitable objects of Weizmann UK. They are divided between Designated Funds which have been set aside by the Trustees at their discretion for specific purposes and General funds which are available for use at the discretion of the Trustees in furtherance of the general objectives of Weizmann UK.

Restricted funds are funds, which have been given for particular purposes and projects (see note 11).

Endowment funds are funds which must be held permanently by Weizmann UK. The funds are invested and the movement in fund values are recognised in the SOFA as investment gains and losses. Income arising on endowed funds is treated as restricted and shown in the SOFA as such.

23

THE WEIZMANN INSTITUTE FOUNDATION (Weizmann UK) (Limited by Guarantee) NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025

1. Accounting policies (continued)

(g) Pensions

Employees of the charity are entitled to join a defined contribution “money purchase” scheme. The charity contribution is restricted to the contributions disclosed in note 4. There were no outstanding contributions at the year end.

Operating lease rentals are charged to the SOFA on a straight line basis over the term of the lease.

Irrecoverable VAT is charged as a cost to the SOFA or capitalised within fixed assets as appropriate.

Financial assets such as cash and debtors are measured at their present value of the amounts receivable, less an allowance for the expected level of doubtful receivables. Financial liabilities such as trade creditors, loans and finance leases are measured at the present value of the obligation. An equity instrument is any contract that evidences a residual interest in the assets of Weizmann UK after deducting all of its liabilities.

(k) Judgements and key sources of estimation uncertainty

In the application of the company’s accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis.

The most significant estimates and assumptions which affect the carrying amount of assets and liabilities in the accounts relate to:

Useful Economic Lives - The annual depreciation charge for property, plant and equipment is sensitive to change in the estimated useful economic lives and residual value of assets. These are reassessed annually and amended were necessary to reflect current circumstances.

Total return on investments – Weizmann UK adopt the use of total return investment powers in relation to its permanent endowment investments. During the current financial year the Trustees allocated 4.5% to income.

The Charity Commission permitted Weizmann UK to use of total return investment powers in relation to its permanent endowment investments by an order granted on 15 August 2006. The power permits the trustees to invest the portfolio to maximise total return and to apply an appropriate portion of the unapplied total return to income each year. Until the power is exercised to transfer a portion of unapplied total return to income (as disclosed in the fund transfers, note 11) the unapplied total return remains invested as part of the Permanent Endowment.

The original value of the permanent endowment at 1 October 2017 is the value of the individual funds as at 1 October 2003 together with any new gifts made in the period 1 October 2003 to 30 September 2025. It has been assumed that for the years to 30 September 2004 and 2009 the dividends and interest less costs has equated to the unapplied total return applied in the periods and as such the value of the unapplied return is equivalent to the net gains and losses in those periods.

The right to the proceeds from certain estate interests in Israel were received pursuant to a legacy. The intention is that these assets be sold by the executors of the estate. The proceeds of sale will be paid to Weizmann UK and then held and invested to produce income supporting cancer and diabetes research at the Institute. One of the properties was sold during the accounting period ended 30 September 2025 and the proceeds will be invested. In the process of offering the other properties for sale, certain difficulties have recently come to light which casts some doubt on their realisable value. Because of this, an estimate of their true value is very difficult. Having taken advice in Israel, the Trustees have reduced the valuation of the properties that remain to £4,913,413.

There may be some tax liabilities associated with the sale of these remaining properties. Because no tax arose in Israel at the time of the benefactor’s death, the capital gain must be determined by reference to the original purchase cost incurred by the deceased or, in the case of one property, the family of the deceased, as the property has been held in their family for a very considerable period of time. In addition, Israel levies a betterment levy on any part of the ultimate gain which reflects the increase in value from a proposed change in use, such as development potential. The executors of the estate have advised us that an estimate of such liabilities is not possible at the present time as they will need to be negotiated with the Israeli Tax Authorities after a sale has occurred. Accordingly, we need to recognise that there may be a currently unquantifiable contingent liability for such tax, which would reduce the value of the bequest.

The value of these properties (without any reduction for potential tax liabilities) has been included in the accounts as an expendable endowment (see Note 11 Funds-Endowed Fund).
