Plus500, the FTSE 250 online trading group, expects full-year revenue and earnings to beat market forecasts after a third quarter in which new customer numbers jumped by more than a quarter.
The London-listed company said revenue for the three months to 30 September rose 11% to $203.2m, compared with $182.7m a year earlier.
Earnings before interest, tax, depreciation and amortisation (EBITDA) increased 7% to $88.4m, giving a margin of 44%.
Analysts' consensus, compiled by Bloomberg, stands at $837.6m for 2026 revenue and $358.0m for EBITDA.
New customers, meaning those depositing for the first time, climbed 27% to 28,747.
Average user acquisition cost fell 14% to $1,150, which chief executive David Zruia described as a combination that is "extremely hard to achieve".
Over the first nine months, revenue rose 11% to $666.1m, while EBITDA grew just 3% to $275.9m as the company spent more on marketing technology.
Interest income fell to $32.1m from $50.7m as global rates declined, but trading income rose to $634.0m from $547.1m.
Plus500 also announced conditional deals to buy two broker-dealers, Hedge in the US and Guru in Brazil, funded entirely from existing cash.
Hedge will give the group access to markets regulated by the US Securities and Exchange Commission, supporting a planned multi-asset "super-app" for US customers in the first quarter of 2027.
Guru will provide Plus500's first local operations in Brazil and a base for expansion across Latin America.
The group's business outside contracts for difference (CFDs), which are leveraged products tracking price moves, accounted for about 16% of revenue and 31% of new customers this year.
New products there include prediction market contracts, where customers trade on the outcome of events, and single stock futures.
Plus500 ended September with no debt and cash of more than $775m, after paying a $87.4m dividend and buying back about $63.5m of shares in the quarter.
