Capita took a mighty tumble after it said it was bracing itself for a financial hit of up to £25million following a cyber-attack that began in March.
The FTSE 250 government contractor, which runs the London congestion charge and collects the BBC licence fee, posted a loss of almost £68million for the first half of 2023.
It estimated that the cyber-attack, which disrupted its IT systems and accessed client data, would cost between £20million to £25million.

That would be higher than the £15million to £20million it had previously forecast. Capita shares tumbled 18.3 per cent, or 4.9p, to 21.94p.
A small amount of data was taken but has now been recovered, Capita said.
Chief executive Jon Lewis added that the company had also been ploughing more funding into its cyber-security systems since the attack.
He has spent several years trying to revive the firm’s fortunes with an extensive restructuring in an effort to shed the company’s image amid a string of profit warnings.
Earlier this week, Capita said Lewis, who has been boss since December 2017, would retire towards the end of the year.
He will be replaced by Adolfo Hernandez, the vice president of telecommunications at Amazon Web Services.

Rolls-Royce ended the week on a high after its shares rose beyond 200p for the first time in more than three years.

The incident cost the group more than £11million, but the firm reiterated its forecasts for this year. Shares fell 4.2 per cent, or 11.5p, to 260p.
