Viva Republica said Thursday that mobile financial service Toss posted over 1.2 trillion won ($866.8 million) in revenue during the first half of 2025, marking a 35.2 percent increase compared to the same period last year.
"The growth momentum that began with the company's turn to profitability in 2024 has continued," the fintech firm stated. "Increased service usage from our strong 30 million user base, along with improved profitability in our core business segments, have driven overall performance growth."
Operating profits reached 154.6 billion won, while net profits came in at 105.7 billion won, driven by robust performance in the consumer and merchant service divisions.
The consumer services division generated 802.1 billion won in revenue, representing 64.9 percent of its total revenue in the first half.
This segment includes services such as money transfers, brokerage, advertising, payments, commerce, securities, tax and authentication. Leveraging a user base that now reaches 60 percent of the Korean population, the division has continued to expand its share of revenue.
Meanwhile, the merchant services division posted 433.3 billion won in revenue, representing 35.1 percent of total revenue during the same period.
This segment covers business-to-business operations, including payment gateway services provided by Toss Payments and offline payment terminal solutions sold by Toss Place. The division is also maintaining a stable growth trajectory, underpinned by an expanding corporate client base.
The company said that operating leverage had a more pronounced impact on performance, as revenue growth outpaced the increase in costs. It added, "This indicates not just expansion in scale, but also healthy growth accompanied by improved profitability."
