Trainline shares fall 19% on CMA probe, Shore Capital sees overreaction

Trainline shares have fallen 19 percent since the CMA opened a booking-fee probe, erasing £185 million in market value — a selloff Shore Capital says prices in an unlikely worst-case outcome.

"The market is pricing in the complete removal of booking fees alongside a structural shift in customer behaviour, neither of which the regulator has demanded," Shore Capital said in a note, keeping its 'buy' rating and 400p price target, more than double the current trading level.

The Competition and Markets Authority is examining whether mandatory fees are shown upfront or only later in the booking journey, a practice known as drip pricing, but has not found any breach of consumer law. Recent CMA penalties in other sectors have ranged from £0.7 million to £5 million, well below the theoretical maximum of 10 percent of global turnover. Only 30 percent of UK tickets carry a booking fee, and most same-day purchases are exempt.

The regulatory overhang could continue to pressure the stock until the investigation's scope becomes clearer, but Shore points to growth in Europe and business-to-business services as reasons to look past the noise, noting the shares now trade at less than five times EBITDA. Investors appeared to take a similar view on Monday, with the stock recovering 2.38 percent, or £4.70, to £202.20 in early trade.

The £30 Million Question

The 19 percent decline since Tuesday implies a permanent £30 million cut to annual earnings before interest, tax, depreciation and amortisation, according to Shore's analysis. That valuation effectively prices in the complete removal of booking fees alongside a structural shift in customer behaviour — a scenario the broker regards as far too severe given the CMA's enforcement record.

Trainline has been in talks with regulators for months and has already explored technical changes to how fees are displayed, indicating the issue is neither new nor a surprise to management. The company's engagement with the CMA predates the formal investigation, which suggests the regulator's concerns are narrower than the market's reaction implies.

The CMA's recent enforcement actions across consumer sectors have produced penalties clustered between £0.7 million and £5 million, a fraction of the theoretical maximum. The regulator's focus on drip pricing — the practice of revealing mandatory fees only at checkout — has targeted disclosure practices rather than the existence of fees themselves, a distinction that matters for Trainline's revenue model.

Only 30 percent of UK tickets carry a booking fee, and most purchases made on the day of travel are exempt, limiting the revenue at risk even in a worst-case scenario. The company's international expansion, particularly in European markets where booking fees are more common, and its growing business-to-business segment provide diversification away from the UK regulatory environment.

At less than five times EBITDA, the shares trade at a discount to UK-listed travel and consumer platforms, reflecting the regulatory overhang. Shore's 400p target price implies more than 95 percent upside from current levels, a bet that the market has overcorrected for a regulatory outcome that is likely to be modest.

The FTSE 250 company's stock has been volatile since the CMA announcement, with Monday's 2.38 percent recovery suggesting some investors are beginning to question the severity of the selloff. The next market-moving event will be any formal findings from the CMA, which typically takes several months to complete its assessment.

For investors, the key question is whether the regulatory probe represents a genuine threat to Trainline's business model or a manageable compliance issue. Shore's analysis suggests the latter, pointing to the narrow scope of the investigation, the company's prior engagement with regulators, and the limited proportion of tickets affected by booking fees.
