LSEG to buy Octus for $3.535 billion in biggest deal since Refinitiv

London Stock Exchange Group announced on October 22, 2026 that it has agreed to acquire Octus, a New York based provider of credit intelligence, data and workflows, for $3.535 billion in cash from funds advised by Permira and Octus management, including founder Kent Collier. The transaction is expected to close in the first half of 2027, subject to regulatory approval, and will be financed with external debt.

The deal is LSEG's biggest acquisition in seven years and its largest since Refinitiv. Reuters reported on October 22, 2026 that LSEG will buy Octus for $3.54 billion, marking its biggest acquisition in seven years as it seeks to bolster its data and analytics offering in the face of AI linked disruption. LSEG bought Refinitiv for $27 billion in 2019 from Reuters parent Thomson Reuters, a deal that turned the exchange group into a data and analytics company. Octus extends that push into private and illiquid credit.

Private credit is estimated at $3.5 trillion, and investors want better data, valuation and portfolio tools for assets that trade infrequently. LSEG said the private markets data, workflow and access solutions segment is worth $7 billion to $9 billion and is expected to grow at a double digit rate. Octus covers the full credit lifecycle with a leading position in illiquid credit, and customers reach it through its platform, an MCP connector or AI workflows.

Octus was founded in 2013 by Collier and has more than 900 employees, 750 customers and over 40,000 individual users across buy-side firms, investment banks, law firms and advisory firms. In 2026 it is expected to generate over $300 million in revenue with strong double digit growth and an adjusted EBITDA margin around 40 percent. LSEG said Octus has posted double digit compound revenue growth since 2022.

Key Facts

The all cash consideration is $3.535 billion, or roughly 11.8 times Octus expected 2026 revenue of more than $300 million. Octus will sit in LSEG's Data and Analytics division, with Collier continuing to run the business and reporting to co-heads Gianluca Biagini and Ron Lefferts. LSEG described Octus as highly complementary to its fixed income products, including IFR news, evaluated pricing, corporate actions, Yield Book and LPC. It also gives LSEG a stronger buy-side footprint among hedge funds and alternative managers.

The TRADE reported on October 22, 2026 that LSEG has agreed to acquire Octus for $3.535 billion in cash, with completion expected in the first half of 2027 subject to regulatory approval and financing through external debt. The TRADE noted that Octus' illiquid and private credit capabilities will sit alongside LSEG's liquid credit products, and that LSEG will develop enhanced products combining Octus content with Workspace, LPC, Yield Book, PRS and Tradeweb. The aim is to give clients a consistent view of a fragmented market with a common data structure, valuation and portfolio management tools.

Reuters reported on October 22, 2026 that LSEG shares jumped 6 percent on the announcement, erasing year to date losses and putting the stock up 4 percent this year, though still down about 24 percent from its 2025 peak on investor concerns that AI could disrupt the group's financial data business and squeeze margins. On an investor call, CFO Michel-Alain Proch said Octus will add $300 million to $320 million to revenue this year, according to Reuters. The deal is expected to be neutral to adjusted earnings per share in the first full year after completion and accretive thereafter.

In its Q3 2026 trading update, also published on October 22, 2026, LSEG reported total income excluding recoveries up 8.8 percent year on year on a constant currency basis. Markets grew 12.5 percent, FTSE Russell 10.2 percent, Risk Intelligence 9.8 percent and Data and Analytics 5.2 percent, while subscription businesses accelerated to 6.6 percent. LSEG raised 2026 guidance to organic constant currency income growth of at least 8.0 percent, from an initial 6.5 percent to 7.5 percent range, and to constant currency EBITDA margin improvement of 100 to 120 basis points.

Reuters reported on October 22, 2026 that LSEG has been under pressure from activist investor Elliott, which disclosed a stake in February and is pushing for portfolio changes as AI affects how investors trade and use data. The Octus deal comes just after Tradeweb Markets, majority owned by LSEG, announced it would buy bond trading platform Trumid for almost $2 billion on Monday. Morgan Stanley was lead financial adviser to LSEG, Barclays Capital also advised LSEG, and Evercore and Goldman Sachs advised Octus shareholders.

Analysis

The strategic logic is defensive as much as offensive. LSEG shares had fallen about 24 percent from their 2025 peak on concerns that AI could disrupt financial data businesses and squeeze margins, according to Reuters. What this really means is that LSEG is paying $3.535 billion for a moat made of specialized content, customer workflows and human expertise rather than for another generic data feed. CEO David Schwimmer said the deal gave LSEG access to Octus highly specialized proprietary data, which no large language model was going to be able to scoop up anywhere, Reuters reported on October 22, 2026. If AI can summarize public filings, it is far less able to replicate a newsroom, analyst team and legal expert network covering distressed credit.

The bigger picture here is that LSEG wants to own the data and workflow layer across liquid and illiquid credit before AI tools commoditize market data. Reuters reported on October 22, 2026 that Tradeweb, majority owned by LSEG, announced it would buy Trumid for almost $2 billion on Monday. Together, the two deals position LSEG as a global leader in fixed income data and trading, according to LSEG. Octus brings the private side, Tradeweb and Trumid bring electronic trading, and LSEG's existing products bring pricing, news and analytics. The combination is more coherent than a simple scale deal because it connects public and private credit in one workflow.

The financial case is credible but not cheap. At roughly 11.8 times expected 2026 revenue, LSEG is paying a growth multiple for a business with an adjusted EBITDA margin of around 40 percent and double digit revenue growth. The deal is expected to be immediately accretive to Data and Analytics organic revenue growth, neutral to adjusted EPS in the first full year and accretive thereafter. Reuters reported on October 22, 2026 that LSEG raised guidance and said it has capacity for further buybacks of £1 billion to £1.5 billion next year. That suggests management is confident enough to absorb the acquisition debt while still returning capital.

Execution risk remains. Octus has more than 900 employees and a founder who will continue to run the business inside a much larger group, which can preserve culture or create friction. The transaction must clear regulatory approval, and LSEG expects to end 2027 around the upper end of its 1.5 to 2.5 times net debt to adjusted EBITDA range on a pro forma basis including the Octus and Trumid deals. The judgement is that the price is defensible if Octus keeps double digit growth and LSEG can sell combined public and private credit workflows. If integration slows or AI reduces the premium for proprietary content, the multiple will look generous.

Why It Matters

For LSEG, the deal shifts the center of gravity from public market data toward private credit, a $3.5 trillion industry where data is fragmented and investors pay for intelligence rather than raw prices. Octus' 750 customers and more than 40,000 users give LSEG a buy-side base among hedge funds and alternative managers that it had struggled to reach. Those customers can be sold LSEG fixed income analytics and Tradeweb execution, while LSEG customers can be sold Octus private credit intelligence. Cross selling is the obvious revenue synergy, though LSEG did not disclose a specific target.

For the broader market, the deal signals that AI disruption is pushing data providers to buy proprietary content and workflow assets rather than compete on generic information. LSEG said 95 percent of its top 200 customers now use LSEG AI products and more than two thirds of its top 50 customers have an MCP connection. That adoption shows why LSEG needs differentiated data to feed those tools. If AI makes it easier to query data, the scarce asset becomes content that cannot be scraped or easily replicated, such as Octus coverage of distressed companies, legal experts and credit analysts.

Next Up

The immediate next step is regulatory review, with LSEG expecting the Octus transaction to close in the first half of 2027. Investors will watch whether LSEG can maintain its raised 2026 guidance of at least 8.0 percent organic constant currency income growth, whether the £3.0 billion buyback programme completes by February 2027, and whether the company delivers further buybacks of £1.0 billion to £1.5 billion in 2027. LSEG also said an NVIDIA partnership announced in October 2026 cuts processing of its Tick History data from hours to seconds.

After completion, the focus will shift to integration and products that combine Octus with Workspace, LPC, Yield Book, PRS and Tradeweb. LSEG will need to show that Octus can grow inside a larger group and that the combined public and private credit offer wins customers without eroding the premium that made the asset attractive. The first full year of ownership will test whether $3.535 billion bought a durable moat or simply a larger data footprint in a market that AI is rapidly reshaping.
