Business / The London Stock Exchange Group no longer makes most of its money from listing companies or matching buyers and sellers — it makes it from selling data. On Thursday it placed its biggest bet yet on where that data business goes next: $3.535 billion in cash for Octus, the New York firm that reads the loan documents, covenants and court filings behind the world's least transparent credit deals.
LSEG buys Octus, the credit intelligence provider owned by Permira funds, for $3.535 billion in cash, the London Stock Exchange Group announced on Thursday, October 22, alongside third-quarter results that showed total income up nearly 9 percent to £2.4 billion. Octus, founded in New York in 2013 by Kent Collier, employs more than 900 people, serves 750 customers and more than 40,000 individual users, and is expected to generate over $300 million of revenue in 2026 at an adjusted EBITDA margin of around 40 percent. The deal, LSEG's largest since the $27 billion Refinitiv acquisition agreed in 2019, is debt-financed and expected to close in the first half of 2027, subject to regulatory approval.

What LSEG announced on Thursday
The deal arrived the way modern exchange-group news usually does: in a regulatory filing before the London open, bundled with quarterly numbers strong enough to help pay for it. LSEG said it has agreed to acquire Octus for a cash consideration of $3.535 billion, buying the company from funds advised by Permira and from Octus' management, including its founder, Kent Collier. LSEG had confirmed earlier in October that it was in talks with Permira, after Reuters reported the discussions on October 13; Thursday's announcement converts those talks into a signed agreement.
The financial shape is deliberately conservative in presentation. The acquisition will be financed with external debt. LSEG says it will be immediately accretive to Data & Analytics organic revenue growth, neutral to adjusted earnings per share in the first full year after completion and accretive thereafter, with no change to its medium-term guidance for underlying EBITDA margin to rise by a cumulative roughly 150 basis points over 2027–2029 from the 2026 baseline. Even after completing its current £3 billion share buyback by February 2027, closing both Octus and the Trumid acquisition announced by its Tradeweb business earlier this month, and keeping capacity for a further £1–1.5 billion of buybacks, LSEG expects leverage at the end of 2027 to sit around the upper end of its 1.5–2.5 times target range, returning to the middle of the range by the end of 2028.
On completion, Octus will sit inside LSEG's Data & Analytics division. Collier will continue to run the business, reporting to Gianluca Biagini and Ron Lefferts, the division's co-heads. Morgan Stanley acted as lead financial adviser to LSEG, with Barclays as financial adviser; Evercore and Goldman Sachs advised Octus' shareholders. The transaction is expected to close in the first half of 2027, subject to regulatory approval.
What Octus actually does
Octus is not a household name, because its customers are not households. Founded in 2013 and headquartered in New York, it sells intelligence, data and workflow tools for the parts of the credit market where information is hardest to get: private, illiquid and distressed debt. Its more than 900 employees serve about 750 customers — buy-side firms, investment banks, law firms and advisory firms — and more than 40,000 individual users, according to LSEG's announcement.
The raw material is unglamorous and valuable: credit documentation that is difficult to access, including private fundamental data, covenants and deal terms, gathered from court filings, transcripts and financial documents and converted into structured, searchable data. Permira, which bought Octus in 2022, says the platform has executed more than four million automated classifications, one million structured data extractions and more than 250,000 content summaries in 2026 alone — turning documents that once took analysts hours into answers delivered in seconds, and doing so in a form designed to plug into AI workflows, including through an MCP connector. Under Permira's roughly four-year ownership, Octus more than tripled its annual recurring revenue, absorbing FinDox, Sky Road and LevPro along the way. The sale is Permira's sixth strategic exit of 2026, in a twelve-month period in which it says it has distributed $13 billion to investors.
The quarter that came with the deal
LSEG paired the acquisition with a third-quarter trading update that underlined why it can afford it. Total income rose nearly 9 percent to £2.4 billion, in line with company-compiled analyst consensus, with gross profit of £2.2 billion also in line. The markets division was the standout, growing 12.5 percent on elevated trading across fixed income, over-the-counter derivatives and equities amid continued geopolitical volatility; FTSE Russell gained 10.2 percent, risk intelligence 9.8 percent and data and analytics 5.2 percent, according to Financial News' account of the update. LSEG also raised its full-year outlook, saying it now expects organic total income excluding recoveries to grow at least 8 percent at constant currencies, up from the 7.0–7.5 percent range set at the half-year stage, with EBITDA margin expansion of 100 to 120 basis points.
That mix matters. The glamorous, volatile part of the group — trading — is booming precisely because markets are unsettled, while the subscription businesses that investors value most for their predictability grew a steadier combined 6.6 percent in the quarter. Octus is bought to thicken the second category: recurring, high-margin subscription revenue that arrives whether or not markets are in turmoil.
Why this matters
Start with the price, because the price is the argument. At $3.535 billion for a business expected to produce just over $300 million of revenue in 2026, LSEG is paying roughly eleven to twelve times forward sales — and, at an adjusted EBITDA margin of around 40 percent, something like twenty-nine times that expected earnings measure. That is not a bargain multiple; it is a scarcity multiple. There are very few independent owners of proprietary private-credit data at scale, and LSEG has decided it would rather overpay for the asset than compete against whoever else owned it.
The strategic logic is written plainly in the announcement. Public and private credit are converging. Private credit — lending by non-bank funds directly to companies — has grown into an industry LSEG estimates at $3.5 trillion, and the market for private-markets data, workflow and access solutions is already $7–9 billion and growing at a double-digit rate. LSEG already dominates pieces of the liquid end of credit: news through IFR, evaluated pricing, corporate actions, and analytics through Yield Book and LPC. What it lacked was the illiquid end — the loans and private deals where there is no exchange price, no ticker, and no public filing a terminal can simply scrape. Octus owns exactly that end, and brings with it a buy-side customer base, particularly hedge funds and alternative investment managers, where LSEG concedes it has historically been under-penetrated.
There is also a defensive war being fought here, and its name is artificial intelligence. LSEG's shares are down about 28 percent from their January 2025 peak, on fears that AI chatbots will commodify financial data and squeeze the margins of firms that merely aggregate it. The company's answer, visible across this deal, is that data which is proprietary — collected by its own teams from hard-to-access documents, structured by its own systems, and embedded in customer workflows — cannot be scraped, summarised or substituted by a general-purpose model. Octus' pitch to Permira's buyers made the same point from the other side: its content is "agentic-ready," built to be consumed by AI workflows rather than displaced by them. LSEG has separately been opening new channels for AI firms to license its data and rolling out its own tools inside Workspace, its Bloomberg Terminal rival. Buying Octus is the largest single statement yet that the group intends to be a supplier to the AI era, not a casualty of it.
How we got here: from Refinitiv to a data empire
Thursday's deal only makes sense against the transaction that remade the company. In 2019 LSEG agreed to buy Refinitiv — the former financial and risk arm of Thomson Reuters — for $27 billion, a deal that transformed a stock-exchange operator into one of the world's largest financial data companies and made data and analytics, not listings, the centre of the group. Every major move since has extended that logic: deeper fixed-income capability, index strength through FTSE Russell, and now, through Tradeweb's planned acquisition of the Trumid bond-trading platform announced earlier this month and the Octus purchase, an attempt to own the credit trade lifecycle end to end — data, analytics, workflow and execution.
The pressure to keep moving is not abstract. Activist investor Elliott Management disclosed a stake in LSEG in February and has pushed for portfolio changes and margin improvement; LSEG has described the dialogue as good and constructive, and launched a record £3 billion share buyback the same month. Shares are broadly flat this year but remain well below their peak. Against that backdrop, a $3.535 billion acquisition is also a message to the activist: management has a growth story of its own, denominated in the fastest-growing corner of its market.
Who wins, who loses, what critics will say
The clearest winner is Permira, which exits with a full realisation of an investment it made in 2022, having tripled the company's recurring revenue — a clean, large strategic exit in a year when private equity has been criticised for struggling to return cash. Octus' customers gain a distribution machine: LSEG can sell Octus' intelligence across a global footprint no independent vendor could match, and can fuse it with Workspace, LPC, Yield Book and Tradeweb. Collier and his team keep their jobs, their brand and their boss.
The harder questions belong to LSEG's shareholders. Eleven to twelve times sales is a price that assumes Octus' double-digit growth — it has compounded revenue at a double-digit rate since 2022 — survives integration, and that cross-selling into LSEG's base materialises at something like the promised scale. The deal is debt-financed while the group is simultaneously running a £3 billion buyback and absorbing Trumid; leverage at the top of the target range through 2027 leaves less room for error if markets calm down and the markets division's 12.5 percent growth cools. Rivals will make the opposite case to customers: that a credit-intelligence firm prized for independence and speed now sits inside a conglomerate with its own trading interests, and that Bloomberg, S&P Global and a generation of AI-native data startups will happily take any customer who agrees. None of that is settled by Thursday's announcement; it is settled by renewal rates in 2028.
What happens next
Three dates and one number will tell the story. First, completion: the deal needs regulatory approval and is expected to close in the first half of 2027, and any extended review of a data merger of this sensitivity would itself be news. Second, the December-to-February buyback window: LSEG has promised to finish the £3 billion programme by February 2027 while funding two acquisitions, a combination that will test the cash generation the third quarter displayed. Third, the 2027 subscription guide: LSEG says Octus is additive to group organic subscription revenue growth of around 7 percent in 2027 — the first results season after closing will show whether the market believes the multiple was worth it. And the number is $3.5 trillion: if private credit keeps growing toward and beyond that mark, the documents behind those loans become more valuable every quarter, and the firm that structured them first owns the toll road. That, in one sentence, is what $3.535 billion bought on Thursday. Signal Post News has been following the quarter's repricing of data and AI businesses, from Samsung's record third-quarter profit in the AI chip boom to Firmus Technologies' withdrawn $44 billion IPO and PepsiCo's third-quarter forecast cut.
