At LSEG, our purpose is to drive financial stability, empower economies and enable sustainable growth. We play a vital role at the heart of the global financial system, supporting our customers as they navigate evolving market expectations and advance their own sustainability goals.

From the development of sustainable finance products and solutions to the management of sustainability-related risks and readiness for incoming regulation, this report highlights our progress in 2025 and the priorities shaping our approach for 2026.

In 2025, regulatory changes and a complex policy environment had a significant impact on the sustainability landscape. Despite that complexity and volatility, customer demand for sustainable finance products was stable and investors continued to embed sustainability into their investment strategies.

Our insights illustrate this momentum. LSEG's 2025 annual asset owner survey found 80% consider sustainability or climate in strategic asset allocation or use related indices. This percentage has risen consistently in recent years, up from 28% in 2021, highlighting the importance asset owners place on these types of risks and the widespread inclusion of sustainability within the broader investment process.

This year, I'm particularly proud to mark the 10th anniversary of the London Stock Exchange's Sustainable Bond Market (SBM). Since its launch, the SBM has supported issuers in raising £359 billion across 967 individual issuances. Going beyond the numbers, the SBM has also helped set market standards and connect issuers with investors seeking credible, transparent, sustainable finance opportunities.

We also deepened our engagement across key markets and policy forums, including participation in global events such as London Climate Action Week and COP30. Through this

engagement, we contributed to dialogue on the development of policies, market practices and regulation that support the transition to a more sustainable financial system.



Across our business operations, we strengthened our understanding of both physical and transition climate risk. We continued to enhance our Climate Transition Plan, ensuring our business remains resilient and responsive

to climate risks.

For our people, we remained focused on driving high performance, growth and a strong sense of belonging. We embedded action plans in each area of the business, ensuring merit-based, inclusive hiring and progression

at senior leadership levels. Despite this progress, we acknowledge that our performance, relative to our goals, needs continued focus.

Looking ahead, I am optimistic about the opportunities for us to support our customers in meeting their sustainability objectives, while engaging with the market more broadly to help shape a sustainable financial system.

  1. The Corporate Sustainability Reporting Directive (CSRD) is a European Union (EU) regulation mandating companies to report regularly on their environmental, social and governance impacts, risks and opportunities. Companies subject to the CSRD must report according to the European Sustainability Reporting Standards (ESRS).

  2. A double materiality assessment (DMA) determines the disclosures required for sustainability reporting, under the ESRS. A DMA considers impact materiality (positive and negative impacts connected with a business) and financial materiality (a company's sustainability-related financial risks and opportunities).

Sustainability governance

Our sustainability governance structure

The LSEG Board oversees the Group's sustainability

strategy, impacts, risks and opportunities, and holds executive management accountable for delivery. Oversight is delegated through a structured governance framework.

The Executive Committee reports to the Board and delegates authority to the Sustainability Committee (chaired by the Chief Risk Officer) to oversee the Group's sustainability strategy and performance. The Sustainability Committee approves the Group Sustainability Report prior to CEO and Board sign off, escalates material changes to strategy or targets to the Executive Committee for approval and ultimately reports to the Executive Committee.

More detail on our sustainability governance can be found online, along with the committees' terms of reference.

Day-to-day responsibility lies with the Group Head of Sustainability, who reports jointly to the Chief Risk Officer and the Chief Corporate Affairs and Marketing Officer, both members of the Executive Committee. This dual reporting line helps ensure sustainability is embedded across risk, corporate affairs and our broader business.

Our Sustainability Policy framework

London Stock Exchange Group plc | Sustainability Report 2025 7



Our Sustainability Policy sets out the minimum requirements, roles, responsibilities and governance for managing sustainability impacts, risks and commercial opportunities across the Group. This policy is supported by a suite of related standards and frameworks. Together, these ensure sustainability considerations are embedded into our core risk management processes and decision-making.

Our sustainability standards and policies are available online.

Board and Executive Committee sustainability experience and skills

The LSEG Board and Executive Committee possess the necessary sustainability knowledge and expertise to provide effective oversight and challenge, including three Non-Executive Directors and the Group CEO with sustainability-specific experience.

Throughout the year, the Board and Executive Committee receive briefings on LSEG's sustainability performance, regulatory developments and market trends to ensure they are equipped to oversee effective delivery of the Group's sustainability strategy and monitor performance.

In addition, Board and Executive Committee members have access to an online learning platform with content for senior leaders and Non-Executive Directors on relevant sustainability topics.

Effective stakeholder engagement helps us to understand our stakeholders' perspectives and respond to their interests, needs and concerns, including those related to sustainability.

Below are our key stakeholder groups and the nature of

our sustainability-related engagement with them throughout 2025. These stakeholder groups also fed into our double materiality assessment.

Sustainability risk at LSEG is defined in the Group risk taxonomy at a strategic level as "the risk of a failure to meet sustainability and ESG requirements from a commercial, regulatory and stakeholder perspective."

This could manifest as specific risks, such as the failure of LSEG's products and services to meet sustainability

regulatory requirements, or the failure to meet stakeholder expectations as measured by ESG ratings, or the failure to deliver on LSEG's Climate Transition Plan. Sustainability risk can also be embedded as a feature of other risks such as operational resilience, people, regulatory, compliance, legal, corporate disclosure, financial and model risks.

London Stock Exchange Group plc | Sustainability Report 2025 8



The Group's Enterprise Risk Management Framework (ERMF) is used to identify, assess, monitor and manage risks appropriately and in line with the Group risk appetite. The Sustainability Risk Management Framework (SRMF) supports the objectives of the ERMF and sets out the principles, minimum requirements, roles, responsibilities and

governance required to identify, monitor and manage exposure to sustainability risks more specifically. The three lines of defence model provides appropriate segregation of duties and clear roles and responsibilities across our divisions, corporate functions, Risk, Compliance and Internal Audit.1

The SRMF applies to all divisions and functions and supports the delivery of LSEG's Sustainability Policy, which sets out the principles through which the sustainability strategy is managed.

Sustainability risks are reported to the Non-Financial Risk Committee (NFRC) when specific issues arise, and to the Board Risk Committee, which has oversight of the Group's risk framework and risk appetite. Sustainability risks are also discussed regularly by the Sustainability Committee.

  1. The three lines of defence is a risk management model: the first line includes functions/divisions that are risk owners; the second line includes functions/ divisions that provide risk oversight; and the third line includes functions/ divisions that provide independent assurance.

Data & Analytics

As sustainability reporting standards evolved during 2025, we adapted our sustainability data collection, taxonomies and products to meet changing regulatory demands. We added Taskforce on Nature-related Financial Disclosures-aligned biodiversity metrics, human capital and governance insights to our ESG data products. Our sovereign solutions were expanded to include additional UN Sustainable Development Goals (SDGs) and climate indicators, and we launched the new SDG Factor-In model, which assesses SDG performance relative to a country's level of development.

We developed a customised data feed which is a flexible multi-asset delivery across sustainability and fundamental data sets - streamlining workflows and tailoring inputs to individual customer needs and reporting requirements. In 2025, we added cloud access to our sustainability data products via Amazon Web Services (AWS) and Snowflake.

Updates were also made in 2025 to our Sustainability Intelligence platform, an end-to-end climate management and disclosure platform. The new release allows inputs to be mapped across multiple sustainability reporting frameworks, avoiding duplication. The new release also empowers corporates to seamlessly onboard, engage and collect sustainability data from their supply chain, while enabling suppliers to respond to multiple requests efficiently.

Also in 2025, we supported Jupiter Asset Management in delivering long-term opportunities in environmental solutions to their clients using LSEG's Green Revenues dataset -offering scalable taxonomy, operational efficiency and validation through a trusted external reference. You can

read the full case study online.

Aligned with our product-related goals, we made the following progress in 2025:

  • We enhanced GHG emissions estimation methodology and expanded coverage to about 60,000 companies across all LSEG climate solutions.

  • We introduced Partnership for Carbon Accounting Financials (PCAF) data quality scores across reported, CDP and estimated emissions to help assess reliability of financed emissions calculations.

  • We launched Implied Temperature Rise (ITR) data in the LSEG Data platform and LSEG Workspace. Based on Network for Greening the Financial System's (NGFS) below 2°C scenarios, the LSEG ITR model provides a range of forward-looking data enabling users to look at a company's GHG emissions trajectories from an alignment perspective.

  • We continued our partnership with the TPI Global Climate Transition Centre (TPI Centre) at the London School of Economics and Political Science (LSE), launched the TPI Management Quality (MQ) scores against the TPI MQ Version 5 methodology and expanded the coverage to include both public and private companies.

  • We released LSEG's Climate MAP Framework on Workspace to provide climate transition data across management, ambition and performance themes.

  • We continued to prioritise transparency in methodology and source data by updating methodology documentation for all products and accompanying all key product launches with publicly available new documentation.

    FTSE Russell

    Throughout 2025 we expanded our sustainable index offerings and partnered with our customers to create custom indices aligned with their investment and sustainability goals. For example, in response to strong customer demand, we expanded the Blossom index series to World Equity and Fixed Income to help investors manage long-term risks.

    We celebrated the launch of the Robeco Climate Euro Government Bond ETF with our partners, Robeco and ING. The reference benchmark, FTSE Climate Collective Transition EMU Broad Government Bond Index, is a custom index

    co-designed with Robeco and ING and incorporates multiple sovereign climate considerations, based on the TPI Centre's Assessing Sovereign Climate-related Opportunities and Risks (ASCOR) framework. It is designed to foster sovereign engagement by encouraging investors to engage with governments and promote policy reforms that accelerate decarbonisation.

    We also continued our partnership with Phoenix Group, one of the UK's largest long-term savings and retirement

    businesses. In 2025, we designed and implemented the FTSE Phoenix Climate Aligned Index Series, a climate transition equity benchmark to help Phoenix Group manage the risks and maximise the opportunities for their customers associated with climate change. You can read the full case study online.

    Aligned with our product-related goals, we made the following progress in 2025:

  • We launched 21 new climate indices.

  • We enhanced product disclosures with sustainable investment data packs, Sovereign Reports and Climate Metrics.

  • We published full ESG and climate index methodologies, supported by value proposition materials.

  • We increased reporting coverage to improve transparency and provide customers with index-level climate and ESG information.

    21
  • We maintained transparent market consultations on proposed methodology changes and actively engaged in industry forums and client advisory committees.

    new climate indices launched in 2025

    Risk Intelligence

    As sustainability becomes a key factor in third-party due diligence, our due diligence reports with sustainability components identify both risks - such as controversial or illegal supply chain activities - and positive initiatives.

    Our global research team operates across 190 jurisdictions and 60+ languages. In 2025, we made improvements to the enhanced due diligence product, including a new data format, research methodology updates and expanded information sources.

    Our World-Check solution supports the detection of a range of sustainability risks, including green crime risk, which helps our clients meet their regulatory expectations pursuant to international anti-money laundering standards (green crime is illegal activity that harms the environment, threatens wildlife and impacts security and stability around the world). Over a third of records within World-Check pertaining to green crimes are not listed by regulatory enforcement or law enforcement authorities, rather this information is obtained through extensive research of credible media sources, requiring specialist expertise, underlining the importance of our

    World-Check solution. In 2025, we launched World-Check on Demand, allowing faster access to product data and quicker decisions around customer onboarding, Know Your Customer, anti-money laundering and sanctions compliance.

    Markets

    The London Stock Exchange's Sustainable Bond Market (SBM) celebrated its 10th anniversary in 2025. Since its inception, the SBM has helped raise £359.2 billion through 967 issuances from over 190 entities, enabling issuers to access investment through green, social, sustainability and sustainability-linked bonds, including a dedicated segment for transition finance. To coincide with the SBM's 10-year anniversary, we relaunched the Sustainable Bond Market Advisory Group. This consultative forum enables market participants to share insights and inform the continued development of the SBM.

    The Green Economy Mark is provided to companies and funds that generate at least 50% of total annual revenues from products and services that contribute to the global green economy (drawing upon the LSEG Green Revenues Classification System). The Green Economy Mark is specifically designed to increase their visibility to investors seeking to deploy their capital into entities that are enabling net positive environmental benefits through the end-use of their products. As of the end of 2025, 97 companies and funds hold the mark, with a combined market capitalisation exceeding £186 billion.

  • Marketplace webinars offering participants targeted expertise on emerging sustainability themes, regulatory developments and investor expectations.

  • An in-person investor relations and sustainability masterclass convened to equip issuers with actionable insights on engaging investors around sustainability.

  • Co-chairing the UN SSE Transition Plan Advisory Group, contributing to the development and launch of a transition plan guidance template.

‌Transforming our own operations

Engaging with market participants and policymakers

Our approach

We engage with market participants and policymakers to inform standards, practices and policies that underpin a sustainable financial market. We participate in industry initiatives, forums and events, and undertake direct engagement, related to the issues that are relevant to our customers.

One area of engagement relates to the development of consistent corporate reporting regulations, as these can directly influence the availability and quality of sustainability information and data which is used by market participants in their investment and capital allocation decisions.

As a result, over recent years our engagement has focused on the adoption of a globally consistent baseline, enabling consistency between regulations and standards in different jurisdictions, and providing forward-looking climate information through publication of transition plans.

Our progress and actions in 2025

Engaging and convening the market

Through 2025 we continued to engage via various market initiatives and forums. For example, LSEG was represented on the Transition Finance Council which was launched by the UK Government and City of London Corporation following the Transition Finance Market Review. We also hosted an event on climate transition plans during London Climate Action Week alongside ISSB and the Transition Pathway Initiative. Additionally, we partnered with the Green Finance Institute and Reuters to host a daily live broadcast show featuring more than 50 global leaders across finance, business and government, putting forward key discussions on climate finance.

In the run up to COP30 in November 2025, we hosted a virtual webinar for customers and an in-person event on sustainable investment in Brazil, as part of Principles for

Responsible Investment's (PRI) conference in São Paulo. We also held a workshop in the 'Climate Action Innovation Zone' in São Paulo, in partnership with the International Transition Plan Network. The workshop brought together senior voices from finance, business, civil society and the public sector to explore the intersections and feedback loops between corporate transition plans, transition finance and climate policy.

Thought leadership and research

Our unique role in the market and our technical expertise enable us to provide thorough, data-driven perspectives on a range of topics. Some examples of thought leadership and research are linked below and more can be found on our website.

Ahead of the EU Omnibus simplification agenda, we published recommendations to simplify the EU's sustainable finance framework. These recommendations related to streamlining the taxonomy criteria, guiding issuers on Scope 3 emissions reporting, ESG fund categories and aligning corporate transition plans. The recommendations can be found online.

Looking ahead

Moving forward, we will continue to engage with the market and policymakers on issues that are relevant to our customers. As we continue to see regulatory change with respect to corporate reporting, we envisage that this topic, together with climate transition planning and transition finance will continue to be engagement themes during 2026.

Our approach

Our climate transition plan (CTP) lays out our ambition, action and governance for the transition towards a lower carbon, climate-resilient economy. This is an evolving area of practice, and our CTP continues to evolve to align with market standards such as the Transition Plan Taskforce (TPT) guidance.

We first published our CTP in 2022 which outlined our

long-term ambition, near-term operational targets (see page 15), our main decarbonisation strategies and our governance mechanisms. Building on this original CTP, in 2024 we published product-related goals. Progress against these product-related goals is described throughout this report and summarised in a guide online.

In 2025, we reviewed our CTP to identify areas for improvement aligned with the TPT framework, which will inform the evolution of our CTP going forward. In line with good practice, we will periodically update and publish our CTP, making this available online.

Our CTP is overseen by the Sustainability Committee,

a sub-committee of the Executive Committee, chaired by the Chief Risk Officer. Operational oversight of the CTP is delegated to the Climate Transition Steering Committee which drives action and monitors progress against our climate targets and ensures appropriate implementation across departments.

We use recognised climate scenarios to model the potential risks and opportunities over the short, medium and long term. For details of our methodology and scenario selection, please refer to pages 39 to 41 of our 2025 Annual Report.

When identifying and assessing climate-related risks or opportunities, we define 'substantive financial or strategic impact' according to the magnitude of the potential financial cost or reputational impact on the Group, as well as the likelihood that the risk will occur. Our assessment of climate-related risks and opportunities is formally integrated into our Sustainability Risk Management Framework (SRMF) and our broader Enterprise Risk Management Framework (ERMF).

Sustainability specialists ensure that climate considerations are reflected in the identification, assessment and mitigation of risks.

Where we identify risks, we work to mitigate and manage them: for example, by reducing our GHG emissions; or by incorporating physical climate risk insights into property management; or through the development of sustainable finance products for our customers.

Our progress and actions in 2025

In 2025, with support from a specialist consultancy, we commenced new climate risk scenario analysis to better understand our transition risks and update our physical risk analysis with the latest science on evolving climate hazards,

Nature-related risks

In 2024, we conducted an initial LEAP (Locate, Evaluate, Assess, Prepare) assessment to explore our nature-related risks and opportunities, in line with recommendations from the Taskforce on Nature-related Financial Disclosures (TNFD). Through our double materiality assessment (see page 6), which concluded in 2025,

we identified water use in data centres as a material environmental impact. We will prioritise our nature-related management actions on water, including improvements to measurement and data collection.

To remain proportionate and aligned with our material sustainability risks, we do not intend to report more broadly on nature at this stage. However, we will continue to monitor our exposure to nature-related risks annually and refine our methodology as needed, ensuring we remain responsive to evolving expectations and emerging risks.

Carbon offsets

LSEG prioritises emissions reductions but uses carbon offsets to account for residual emissions that we have not yet been able to reduce. Consistent with previous years, we continue to offset our emissions from Scope 1, Scope 2 and Scope 3 (fuel- and energy-related activities, business travel and colleague commuting).

We ensure we buy high-quality offsets by applying rigorous criteria aligned with recognised market standards. Key considerations include 'additionality' (ensuring the emissions reductions associated with the offset project would not have otherwise occurred), 'permanence' (long-term durability of the carbon removal) and third-party verification through bodies such as Gold Standard or Verra.

The analysis highlighted that the most significant physical risks relevant to LSEG include heat stress, heavy precipitation, water stress and flooding, with exposure expected to rise under higher-emission scenarios. While current financial impacts from acute hazards such as flooding and windstorms are limited, their frequency and severity are projected to increase. Transition risks are focused on the evolution of carbon pricing and regulatory requirements, which could influence costs and market dynamics. These risks also present opportunities to innovate and strengthen resilience, in both operations and customer solutions.

You can read more about these physical and transition risks on pages 39 to 41 of our 2025 Annual Report, as part of our Task Force on Climate-related Financial Disclosures (TCFD) reporting.

Looking ahead

In 2026, we will seek to implement recommendations from our 2025 climate risk analysis, to improve our business resilience, manage financial and regulatory risk and develop our products and services.

Based on the work conducted in 2025, we will evolve our CTP to strengthen our ability to respond to future regulation, enhance our management of climate risks and opportunities and respond to stakeholder demand for credible,

science-based transition plans.

Climate

Managing our emissions

Our approach

One way we manage climate risk is by reducing the GHG emissions associated with our business operations. We do this by using renewable energy sources where possible, increasing energy efficiency, reducing travel-related emissions and reducing the emissions from our supply chain.

We manage emissions across five main areas:

  • Property: emissions from our global network of offices (Scope 1 and 2 emissions and Scope 3 Category 3 and

    Category 5 emissions).

  • Data centres: emissions associated with the data centres that we use (Scope 1 and 2 emissions, Scope 3 Category 3 and Category 8 emissions).

  • Supply chain: emissions arising from goods and services we purchase and capital goods (Scope 3 Category 1, 2 and 4 emissions).

  • Business travel: emissions arising from business travel by air, rail and road, and hotel accommodation from colleague business travel (Scope 3 Category 6 emissions).

  • People: emissions from colleague commuting on public transport, private vehicles or LSEG-supplied shuttle services and colleagues working from home (Scope 3 Category 7 emissions).

    We have set science-based targets, aligned with the goal

    of the Paris Agreement and approved by the Science Based Targets initiative (SBTi), as shown in the charts below.

    SBTi requires companies to review their targets when there has been a significant change to the business, the emissions calculation methodology or reported emissions. During 2024, we enhanced our methodology and reported a significant reduction in our emissions. We are thus required to reassess the suitability of our 2019 emissions baseline year and the current 2030 targets approved by SBTi. We will explore this in 2026.

    LSEG continues to enhance our emissions reporting through improved methodologies, reduced reliance on estimates and proxies and strengthened data collection and assurance processes. As part of this work, adjustments exceeding our 5% materiality threshold have led us to restate our 2024 figures with a 4% net impact, due to methodology refinement and the correction of errors within Scope 3 data. All 2024 comparatives and year-on-year metrics in this report use the restated figures to present the most accurate data available. For more details, refer to the Basis of Reporting within the 2025 Sustainability Databook.

Emissions performance

Overall, our 2025 Group greenhouse emission footprint reduced by 7% against 2024.∆ Our Scope 1 emissions reduced by 25% and our Scope 2 (location-based) emissions reduced by 8% when compared with 2024. Contributors to this include reduced energy consumption, operational efficiencies (e.g., reduced generator run times), reduced business travel as

well as ongoing data improvements, including greater use of actual rather than estimated data and updated assumptions, such as confirming absence of certain fuel sources.

Progress against our science-based targets continues. We saw a 15% reduction against prior year against our target for Scope 1 and Scope 2 (market-based) emissions and an 86% reduction against our 2019 baseline. We saw a 26% reduction against prior year against our Scope 3 target (business travel, colleague commuting and fuel- and energy-related activities) and an overall reduction of 62% against the 2019 base year. These reductions were driven largely by a Group-wide reduction in business travel in 2025.

We continue to work with our suppliers to set their own science-based targets. In 2025, suppliers responsible for 56% of our emissions from purchased goods and services have either already set or have committed to setting science-based targets. This is against our target to achieve 67% by the end of 2026.

Emissions-reduction activities

Throughout 2025, we explored a range of decarbonisation initiatives. For example, we invested in an 800kW solar photovoltaic (PV) system for the roof of our Malabe campus in Sri Lanka. The system was installed and tested in 2025 and is awaiting grid connection to go live in 2026. Once connected, we anticipate the system will offer on-site renewable energy generation equivalent to 61% of the daytime energy consumption and deliver long-term cost savings. Elsewhere, we are installing smart-building technology in three pilot office locations, with an aspiration to scale this across more sites in future. The technology automates and optimises a building's operations using real-time data and reduces unnecessary energy consumption.

In 2025, transformation programmes continued to lower the density of equipment across our data centre sites with the reduction being driven by a new software-defined network architecture and the movement of on-premises applications to our core cloud providers, where energy consumption can be more efficiently managed.

Our procurement team engaged 53 more suppliers in 2025 (compared to 2024) to align with our climate targets and we convened collaborative sessions with suppliers to share good practice. We also enhanced our emissions tracking using LSEG's Sustainability Intelligence platform, reducing our reliance on estimated data to improve the quality of our Scope 3 emissions calculations.

During 2025, the travel team enhanced internal tracking and reporting to enable executive leaders to make informed travel decisions for their areas of the business. Also in 2025, we piloted an enhanced business travel approval approach to enable greater oversight.

We also launched an LSEG-wide colleague commuter survey in 2025. The survey received a nearly 70% response rate and provided valuable data and clear insights into modes of transport and commuting patterns that will improve our emissions reporting and decarbonisation strategies.

Looking ahead

We will continue work to review our climate targets and baseline year and will update these as required. We will also continue our focus on switching to renewable sources

of energy where available and managing emissions from our highest emitting categories. To reduce our Scope 3 emissions, we remain focused on engaging with our suppliers to support them in setting their own emissions-reduction targets.

Supporting and developing our colleagues

Our approach

Our people strategy supports our business ambition by driving high performance, growth and a strong sense of belonging. We bring this to life by living our values, using data-driven insights, embracing digital tools and continuously

evolving how we work. Our approach to colleague development is shaped by our strategic priorities and long-term workforce plans, helping us build the critical skills we need now and for the future.

Our people strategy is overseen by the LSEG Board. The Chief People Officer is a member of the Executive



Committee and is accountable for all aspects of our people strategy, including building an inclusive and sustainable high-performance culture, aligning organisational design, talent and reward to our strategic objectives and developing great leaders.

Our progress and actions in 2025

Listening to our colleagues

We leverage a multi-channel employee listening approach

to understand colleague sentiment and experience, ensuring we can build and sustain an inclusive, high-performance culture. Through our annual LSEG Engage survey, targeted pulse surveys and other touchpoints, we gather valuable insight into what matters most to our people.

The 2025 LSEG Engage survey explored key drivers of performance and experience, including engagement, strategy, people-leader support and belonging. We also introduced a new forward-looking open-ended question, "If you could change one thing at LSEG, what would it be?"

in order to deepen our understanding of colleague priorities and opportunities for improvement.

20,448 colleagues (78% of our total number of colleagues) shared their feedback, leaving 50,028 comments. The key themes in the comments related to culture, compensation and recognition, communication, customer focus and process simplification. The overall engagement score is a combined

measure determined from questions on colleague satisfaction and likelihood to recommend LSEG as a great place to work. Our overall engagement score, 74, remained stable from 2024.

The survey revealed positive highlights on how most colleagues feel empowered and receive the support and feedback they need from their people leaders. Areas for improvement included communicating LSEG's strategy internally and a need for continuing focus on customer experience and process simplification.

In 2025, we also conducted an LSEG-wide sustainability survey to understand what colleagues think about our sustainability approach. Topics that scored most highly included LSEG's commitment to sustainability, how sustainability is embedded in our values and culture, and the benefits of volunteering. The survey also revealed colleagues wanted more access to sustainability insights and educational

materials and they would like to understand more about how we're supporting customers with our sustainable finance products.

Supporting wellbeing

Our holistic approach to colleague wellbeing helps our people thrive and bring their best selves to work. Our four-pillar model supports a healthy, resilient organisation:

  • Emotional: supporting mental health, stress management and resilience

  • Physical: encouraging healthy lifestyles and mobility

  • Financial: promoting financial security and confidence

  • Social: building connection and belonging across our workforce

    Day-to-day management of colleague wellbeing programmes rests with the Group Head of Total Reward and Performance, who reports to the Chief People Officer. All colleagues can access the Employee Assistance Programme, a free, anonymous service available 24/7, and benefit from a suite

    of supportive policies, including generous global parental, caregiver and bereavement provisions, which underscore our ongoing investment in colleague wellbeing. Full details of our wellbeing approach can be found online.

    Career development, skills and learning

    Our people strategy drives high performance, growth and colleague development, helping us build the critical skills we need now and for the future.

    LSEG uses Career Navigator to support building future-ready skills and career growth. This personalised platform helps colleagues identify skills gaps, explore career paths and find internal opportunities - aligning individual ambitions with our business strategy.

    We also run campaigns and initiatives throughout the year to support colleague career development and learning opportunities. In 2025, these included:

  • A global campaign called "Crucial Conversations -Performance and Career" designed to help colleagues and their leaders with career development conversations. 134 workshops were delivered to 3,622 colleagues in 2025.

  • The launch of "Boost", a two-year career development programme for high-potential engineers. 24 participants were paired with Group Leaders as sponsors, who provide personalised guidance, leadership exposure and support in building key competencies.

  • Continued our Group-wide learning and development offering - Grow at LSEG - providing interactive, bitesize workshops to develop skills. 198 workshops were offered with 4,497 colleagues participating.

    78
  • Launched our Product Academy to build foundational awareness of the product operating model and principles, and advance the capabilities of product professionals through deep skill-building and behavioural transformation.

Supporting and developing our colleagues continued

We've built a clear, consistent approach to assessing and rewarding performance. At year end, colleagues receive equally weighted ratings for what they achieve - aligned to personal, divisional and Group objectives - and how they deliver, based on our values of Integrity, Partnership, Excellence and Change. Quarterly reviews with people leaders support ongoing feedback, progress tracking and development planning.

We avoid redundancies wherever possible, but where organisational changes require it, workforce restructuring is conducted in a responsible manner in line with all applicable local laws and practices. Impacted colleagues and their leaders can access a range of information, support and guidance to help them navigate the process and identify new employment opportunities.

Sustainability knowledge building

We provide tools and resources to help all colleagues build and deepen their sustainability knowledge. We do this via the Sustainability Campus, which is a learner-led resource available on the Group intranet with pathways and dynamic content for colleagues to upskill on sustainability. It links to partner resources and includes internal webinars on key sustainability topics.

Sustainability Unlocked is an external learning tool with video-led content aimed at colleagues whose roles cover sustainability, with recommended learning pathways depending on their role. In 2025, we created new learning pathways focused on sustainable finance, regulation and greenwashing.

To deepen understanding amongst specific colleague groups, we ran several training sessions during 2025, including sessions on anti-greenwashing, sustainability and geopolitics, sustainable finance and human rights.

Looking ahead

Creating an inclusive culture



Our approach

Our strategic ambition for creating a diverse and inclusive culture at LSEG has four pillars and six levers as shown in the diagram below.

Our approach is governed by a global Steering Group comprising Executive Committee members and key senior leaders. Divisional leadership teams lead the delivery of action plans within their business areas, continuously tracking, measuring and sharing progress at that level.

Our progress and actions in 2025

We continued with merit-based hiring and promotion, working towards our goals of maintaining at least 40% women in senior leadership and of 25% ethnic minority representation in senior leadership by 2027.1, 2

As at the end of 2025, the number of women in senior leadership stood at 36% (down from 41% in 2024) and ethnic minority representation in senior leadership stood at 15% (down from 16% in 2024).

Both figures reflect fluctuations in our senior leader population. We remain committed to merit-based, inclusive hiring and progression at senior leadership level, tracking progress via tailored business unit action plans. We will continue to monitor gender and ethnic diversity across all levels and adapt our recruitment and talent management strategies to ensure equity and attract a broader range of candidates, in compliance with relevant laws.

In accordance with the Financial Conduct Authority's UK Listing Rule 6.6.6R(9) and 6.6.6R(10) and section 414C(8)(c) of the Companies Act, we report further information on diversity and inclusion in our 2025 Annual Report.

Inclusion networks

Our nine inclusion networks, each supported by an Executive Sponsor and open to all, play a vital part in advancing our cultural approach and values. They support the implementation of decisions from our Steering Group and divisional strategies. In 2025, our networks organised events focused on awareness, career development and wellbeing - helping colleagues deepen their understanding of diverse communities.

Building capability

We encouraged the completion of voluntary Fundamentals training, with an average completion rate of 73% for modules covering topics such as bias, anti-racism, accessibility and LGBTQ+ inclusion. These modules were also embedded in business unit action plans. We're now developing new content on neurodiversity and mental health, which will be included

in new joiner onboarding to support learning throughout the employee lifecycle.

To complement our existing Fundamentals learning modules, in 2025 we leveraged a digital culture tool to scale cultural competencies across our business. The aim was to increase our ability to collaborate across cultures, enhance our customer experiences, help colleagues navigate a complex global landscape and support people leaders to manage multicultural teams.

Global Parental Leave: one year on

As of the end of 2025, 1,136 colleagues have utilised our Global Parental Leave Policy and 55% of users are male. Introduced in 2024, the policy demonstrates our commitment to supporting family life, and we're especially encouraged by the strong feedback from male colleagues, highlighting its inclusive impact.

London Stock Exchange Group plc | Sustainability Report 2025 20



Looking ahead

Throughout 2026, we will remain committed to our goals and action plans. We will also take a strategic approach to embed accessibility into our inclusion efforts and build disability confidence across the Group. A key focus on neurodiversity will strengthen our broader capabilities to support colleagues through equitable processes. Our three-phase plan includes integrating neurodiversity into our learning, clarifying

neuro-accessible assessments, launching an awareness campaign and establishing a neurodivergent community within the LSEG Accessibility Network.
