This means that the organisation had scope lo hire additional staff as well as to redefine and develop ils core functions. In the period, Transitionzero hired a total of 16 new team members and continues lo hire at a steady rate,. il is projected that by the end of the first quarter of Financial Year 202512026 the team will have grown to 44+ Specific updates regarding strategic aims and impact are detsiled further down in this report. Change management. Following COP28, we had a renewed focus on improving our internal processes to drive successful outcomes. This has resulted in extensive change throughout Transitionzero's operations, from company meetings through documentation and targeting of key issues. This focus on constant improvement has yielded good outcomes in employee satisfaction and productivity, and we are beginning to see the results in product completion and launch. Salary grading. Between February and April, we worked on revising our salary structure to give a more accurate representation of salaries across multiple disciplines al Transitionzero, including the development of entirely new bands for Product and Analysis (which were previously nested under'TechnOl￿Y l. This work quired research and benchmarking against similar organisations with the objective of paying good wages and avoiding overcommitting our people, thereby reducing the risk of bumoul. The salary grades revision has freed up £260K compared to the original forecast and budgeted 1 OO/a average salary increase acmss the organisation. The average salary increase across Transilionzero is 5 /0 on salaries for 2023124. Codifying our culture and promoting employee wellbeing. Given the items outlined above, one of the most pressing issues for the Executive team this period was company culture. Feedback from various teams indicates that employees were experiencing increased stress during periods of heavy workloads, under- resourcing, communiGalion issues, and light deadlines. The Executive team recognises that sustsinable productivity cannot be achieved al the expense of employee well-being. To address this, we developed a comprehensive work plan for our People team and engaged an exlemal training provider. This provider has been providing ongoing training to different cohorts within our organisation. Our immediate focus was lo review and improve our reward schemes, performance management prO￿sses, and general operational practices. Finances. In terms of financial management, we continued to enhance our financial prO￿dureS and processes. The finance function is now comprehensively handled in-house, with the Financial Controller overseeing all accounting and bookkeeping opemtions. Additionally, the Financial Controller maintains and updates financial forecasts and budgets. We review all expenditures monthly and allocate each transaction lo the appropriate grants. Importantly. the finance team consistently provided monthly financial reports to the CEO to support well-informed financial decisions and future planning. The Executive team uses a forecasting sheet to predict the impact of spend and hiring decisions. Page 3

The advancement of education and promotion of research into environmental protection and sustainable development in subjects including bul not limited lo clean energy, air pollution, renewable technologies and sustainable finan￿. For the purposes of this definition, 'sustainable development. means development which meets the needs of the present without compromising the ability of future generations to meet their own needs. Strategic Aims and Intended Effect Transitionzero's mission is to help more teams working on energy transition planning to use system models lo make better decisions, faster. Objectives for the Year Transitionzero's Objects as stated in its Articles of Association are= 2.1 the promotion of consetvalion, protection and improvement of the environment, in particular (but not limited lol, by promoting the reduction of carbon emissions and the improvement of air quality., and 2.2 the advancement of education and promotion of research into environmental protection and sustainable development in subjects including bul not limited lo clean energy, air pollution, renewable technologies and sustainable finan￿. For the purposes of this Article 2, "sustainable development" means development which meets the needs of the present without compromising the ability of future generations to meet their own needs." Strategies to Achieve the Yea￿S Objectives To achieve our charitable objectives, we are building an open-source energy system model without usability barriers and creating a user network effect through a scalable partnership model to support the development of a global standard for energy transition planning data. Our theory of change posits that once govemments in emerging economies realise that clean energy is the most cosl-effective form of new energy in nearly every global market, they will prioritise the policy changes needed to ensure clean energy is deployed lo meet their development goals. Previously, our impact strategy combined lowering entry barriers for system modelling with creating content lo highlight clean energy's cosl-effectiveness. Now, we believe our greatest impact may lie in ensuring policymakers effectively use our modelling platform and in prodLJcing content that demonstrates ils value. Our current objectives are to ensure all OLJtputs funded by reslricled grants are delivered on time and to the funder's satisfaction, to successfully launch Scenario Builder and build a modelling methodology for future projects.

Details of the extent to which the audit was considered capable of detecting irregularities, including fraud and non-compliance with laws and regulations are set out below. 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.or .uklauditorsres onsibililies. This description forms part of our auditor's report. Extent to which the audlt was consldered capable of detectlng Irregularltles, Includlng fraud Irregularities. including fraud. are instances of non-compliance with laws and regulations. We identified and assessed the risks of material misslatemenl of the financial statements from irregularities. whether due lo fraud or error, and discussed these between our audit team. We then designed and performed audit procedures responsive lo those risks, including obtaining audit evidence sufficient and appropriate lo provide a basis for our opinion. We obtained an understanding of the legal and regulatory frameworks within which the charitable company operates, focusing on those laws and regulations that have a direct effect on the determination of material amounts and disclosures in the financial statements. The laws and regulations we considered in this context were Charities Act 2011 together with the Charities SORP IFRS 1021. We assessed the required compliance with these laws and regulations as part of our audit procedures on the related financial statement items. In addition, we considered provisions of other laws and regulations that do not have a direct effect on the financial statements but compliance with which might be fundamental to the charitable company s ability to operate or to avoid a material penalty. We also considered the opportunities and incentives that may exist within the charitable company for fraud. The laws and regulations we considered in this context for the UK operations were General Data Protection Regulation IGDPR}, Health and safety legislation and Employment legislation. Page 15

Independent Auditor's Report to the Members and the Trustees of TransitionZero

Auditing standards limit the required audit procedures to identify non-compliance with these laws and regulations to enquiry of the Trustees and other management and inspection of regulatory and legal correspondence, if any.

We identified the greatest risk of material impact on the financial statements from irregularities, including fraud, to be within the timing of recognition of income, and the override of controls by management. Our audit procedures to respond to these risks included enquiries of management and the trustees about their own identification and assessment of the risks of irregularities, sample testing on the posting of journals, reviewing accounting estimates for biases, reviewing regulatory correspondence with the Charity Commission, reading minutes of meetings of those charged with governance. Our audit procedures to respond to income recognition risks include sample testing income throughout the period agreeing to supporting documentation and reviewing income received either side of the year end to ensure this has been recognised correctly.

Owing to the inherent limitations of an audit, there is an unavoidable risk that we may not have detected some material misstatements in the financial statements, even though we have properly planned and performed our audit in accordance with auditing standards. For example, the further removed non­ compliance with laws and regulations (irregularities) is from the events and transactions reflected in the financial statements, the less likely the inherently limited procedures required by auditing standards would identify it. In addition, as with any audit, there remained a higher risk of non-detection of irregularities, as these may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal controls. We are not responsible for preventing non-compliance and cannot be expected to detect non­ compliance with all laws and regulations.
