The bank’s stock rose as much as 10 per cent, making it the top gainer on the FTSE-350 Banks Financial Index early on Thursday.
Aldermore, the latest in a wave of banks to list in London with the aim of challenging Britain’s “Big 5” lenders, reported underlying pretax profit of 44 million pounds for the six months ended June.
This was above the consensus forecast of £40m compiled by Aldermore with input from eight analysts.
The so-called ‘challenger’ bank joins rivals Virgin Money, OneSavings Bank Plc and Shawbrook Group Plc in reporting a bigger first-half profit, fuelled by greater lending to small and medium-sized enterprises.
Aldermore said it was on track for net loan growth of about £1.4bn, or 30 per cent, for full-year 2015.
RBC Capital raised its rating on the stock to “outperform” and increased its target price to 325 pence from 300 pence, citing lower-than-expected impairments.
