Summary
The 2025 preliminary results of London Stock Exchange Group (LSEG) highlight a company strengthening its position as a global financial data and market infrastructure platform, supported by strong financial performance, expanding AI capabilities, and a powerful shareholder base that includes **Microsoft and **Elliott Investment Management.
LSEG delivered solid organic revenue growth of around 7%, EBITDA margins above 50%, and record free cash flow, reflecting the scalability of its integrated ecosystem spanning Data & Analytics, FTSE Russell indices, Risk Intelligence, trading venues, and post-trade clearing infrastructure.
A central theme of the results presentation is management’s view that artificial intelligence represents a structural opportunity rather than a threat. The company argues that approximately 98% of its revenues are tied to proprietary datasets, regulated workflows, benchmarks, and market infrastructure, assets that cannot be replicated by generative AI models. Instead, AI is expected to increase the value and consumption of LSEG’s data by embedding it into financial workflows and analytics tools.
Strategically, the partnership with Microsoft plays a critical role in this transformation. Through the integration of LSEG datasets into Microsoft Azure and AI environments, the company is expanding its data distribution, enabling new AI-driven analytics products, and increasing the intensity of data consumption across financial institutions.
At the same time, the presence of activist investor Elliott Investment Management reinforces capital allocation discipline and governance oversight, supporting the company’s focus on operational efficiency and shareholder returns.
Reflecting confidence in its cash generation and long-term growth prospects, LSEG announced a new £3 billion share buyback program, following £2.1 billion of repurchases completed in 2025. The program is supported by strong free cash flow generation exceeding £2.4 billion, allowing the company to return capital to shareholders while maintaining balance-sheet flexibility for future investments and acquisitions.
Looking ahead, management expects mid- to high-single-digit revenue growth, further margin expansion, and double-digit growth in free cash flow per share, driven by continued demand for proprietary financial data, expansion of market infrastructure services, and increasing adoption of AI-powered analytics.
Overall, the results reinforce LSEG’s transformation into a high-margin financial infrastructure platform combining data, analytics, and trading ecosystems, supported by strategic technology partnerships, disciplined capital allocation, and significant shareholder returns.
Key Strategic Drivers Behind LSEG’s FY25 Results
1. AI Is an Opportunity, Not a Threat for Financial Data Providers
One of the most important arguments presented by London Stock Exchange Group is that artificial intelligence strengthens, rather than weakens, its competitive positioning.
Management highlighted that approximately 98% of group revenues are linked to proprietary datasets, regulated workflows, indices, benchmarks, or trading infrastructure, rather than generic public information.
This distinction is crucial. Generative AI models can aggregate and process public information, but they cannot easily replicate proprietary financial datasets that are continuously updated, validated, and embedded within regulatory or operational workflows.
Examples include:
- benchmark indices used in investment products
- anti-financial-crime databases such as World-Check
- real-time trading and clearing infrastructure
- historical tick data and transaction records
In practice, AI increases the value of these datasets because automated analytics tools require trusted, structured, and legally defensible financial data. As AI systems become integrated into financial workflows, the consumption of proprietary datasets may actually increase.
2. Data & Analytics Is Evolving Beyond the Traditional Terminal Model
Another key theme is the transformation of LSEG’s Data & Analytics division, historically associated with desktop platforms such as Eikon.
The company has completed the large-scale migration from Eikon to Workspace, a modern modular platform designed to integrate with cloud environments, APIs, and AI-driven analytics.
This transformation changes the economic model of financial data distribution. Instead of relying solely on desktop subscriptions, LSEG increasingly distributes its data through multiple channels:
- cloud-based data feeds
- APIs integrated into institutional systems
- analytics services embedded into enterprise environments
- AI-powered interfaces and applications
This approach significantly expands the addressable market, allowing LSEG data to reach users who may not traditionally subscribe to a financial terminal but still require structured financial datasets within their workflows.
3. Market Infrastructure Businesses Provide Structural Growth
While data and analytics attract most investor attention, the management emphasizes the importance of LSEG’s Markets and Post-Trade businesses.
These include:
- electronic trading platforms
- foreign exchange venues
- interest rate swap clearing
- derivatives clearing
- repo markets
- post-trade settlement infrastructure
These activities benefit from long-term structural trends in financial markets, including:
- increased electronification of trading
- regulatory requirements for clearing
- rising demand for risk management
- growing market complexity
Because these businesses operate within highly regulated infrastructure environments, they typically benefit from high barriers to entry and network effects.
Over the last five years, LSEG’s market infrastructure activities have delivered double-digit growth in transactional revenues, demonstrating that the company’s growth is not dependent solely on financial data products.
4. The Microsoft Partnership Is Central to the Technology Strategy
The strategic partnership with Microsoft represents one of the most transformative initiatives for the company.
This collaboration includes:
- migration of LSEG’s core data infrastructure to Microsoft Azure
- development of AI-driven analytics tools
- integration of financial data into Microsoft productivity environments
- distribution of datasets through AI applications
This partnership creates three strategic advantages.
First, it allows LSEG to scale its data infrastructure globally using Microsoft’s cloud architecture.
Second, it embeds LSEG’s datasets into new workflows used by financial professionals, expanding the company’s distribution network.
Third, the integration with AI systems enables new data consumption patterns, which could support hybrid pricing models combining subscriptions and usage-based charges.
In essence, the partnership positions LSEG at the intersection of financial data infrastructure and enterprise AI adoption.
5. Strong Cash Generation Enables Aggressive Shareholder Returns
In 2025, LSEG generated more than £2.4 billion of free cash flow, supported by its high-margin subscription and infrastructure businesses.
This financial strength allows the company to pursue a balanced capital allocation strategy that includes:
- investment in product development and AI capabilities
- selective acquisitions
- dividend growth
- large-scale share buybacks
Most notably, LSEG announced a new £3 billion share buyback program, following £2.1 billion of repurchases already completed during 2025.
The buyback program reflects management’s confidence in the company’s long-term prospects and supports growth in earnings per share and free cash flow per share.
6. Strong Shareholder Alignment Through Microsoft and Elliott
Another important element highlighted in the results is the composition of LSEG’s shareholder base.
Microsoft holds a strategic equity stake in the company as part of its technology partnership.
At the same time, Elliott Investment Management is among the largest shareholders and has historically advocated for strong governance, operational efficiency, and disciplined capital allocation.
This combination creates a powerful dynamic:
- Microsoft provides technological innovation and long-term strategic alignment
- Elliott provides shareholder oversight and financial discipline
The presence of both investors reinforces market confidence in the company’s long-term strategic execution.
2026 Guidance
For 2026, LSEG guided to free cash flow of at least £2.7 billion, implying continued growth in cash generation.
This guidance is supported by several structural drivers:
1. Continued revenue growth
Management expects 6.5–7.5% organic revenue growth in 2026, driven by accelerating subscription businesses and continued strength in market infrastructure activities such as clearing and trading platforms.
Given the high operating leverage of LSEG’s business model, incremental revenues should translate into disproportionately higher operating profit and cash flow.
2. Margin expansion
The company also guided to 80–100 basis points of EBITDA margin expansion.
Margin expansion is supported by:
- the completion of major integration investments following the Refinitiv acquisition
- productivity gains from internal AI tools and automation
- increased scale in high-margin data and analytics services
Higher margins naturally translate into stronger operating cash flow generation.
3. Declining capital intensity
Another important driver of free cash flow improvement is the expected decline in capital expenditures.
Management expects CapEx intensity to fall to approximately 9.5% of revenue in 2026, as the company moves beyond the heavy infrastructure investments required for the Refinitiv integration and cloud migration.
Lower capital intensity means that a greater share of operating profit can be converted into free cash flow.
