After underestimating build costs on nine schemes in its Southern Division, Vistry said it now expects FY24 adjusted pre-tax profit to be £80m lower at around £350m, a hit of about 20%. FY25 forecasts have also been downgraded by £30m.

The broker cut its target price for the stock from 1,380p to 1,000p and kept a 'hold' rating.

Shares were up 0.3% at 966p by 1015 after tumbling 24% the previous session.
