Trainline has increased its guidance range across some financial metrics, after it delivered "strong growth" in the first half of the 2025 financial year.

In a statement, the company said that following a strong start to its second half, it had revised upwards its previously stated guidance range, which was originally set in May and was improved in September.

It now expects to generate year-on-year net ticket sales growth of between 12% to 14%, with the previous guidance set between 8% and 12%.

Furthermore, it expects year-on-year revenue growth of between 11% and 13%, having previously sat at the top end of the 7% to 11% range.

Its adjusted EBITDA for net ticket sales has been increased marginally from 2.5% to 2.6%.

The update comes after Trainline recorded a 14% increase in year-on-year ticket sales in the six months to 31 August, taking the total to £3bn.

Revenue also increased by 17% in this period to £229m, while its adjusted EBITDA jumped 44% to £82m.

Investment director at AJ Bell, Russ Mould, said: "The company is benefiting from operating leverage, with its costs not going up as quickly as revenues, as it builds on an already dominant market position in the UK and expands in Europe.

"The company makes money by earning a commission and fees on ticket sales and generating revenue from advertising and ancillary services like insurance. While in theory there aren’t huge barriers to entry to competition, Trainline now has an established brand and platform which others might struggle to match.

"The potential threat of a state-backed ticketing rival in the UK remains but it does not seem to be a priority for the current government. Rail nationalisation could also complicate things but these remain problems for another day, with Trainline doing pretty handsomely right now."

Trainline’s half year results are set to be announced on 7 November.
