The lender had initially announced last September its plans to launch an IPO on the London Stock Exchange, but shelved the idea just a month later after a period of declining global equity markets.
An initial price of between 217p and 265p per share had been targeted for the initial launch, valuing the bank at around £870m.
However, the report suggests Aldermore will have to seek a lower price per share this time around to attract investment, despite markets having stabilised.
The lender has around £4.4bn in loans outstanding, and most recently reported pre-tax profits of £18.6m for the half-year to 30 June 2014, up from £5.3m a year earlier.
Aldermore refused to comment on the IPO plans.
