The new funding was initiated and managed by its founding sponsor AnaCap Financial Partners and the capital was provided by hedge funds Toscafund and Lansdowne Partners.
The deal will also establish a wider dialogue with UK institutional investors as Aldermore continues to review its capital markets strategy which may, amongst other strategies, include an initial public offering.
Phillip Monks, Aldermore CEO, said: “I am delighted by the investor appetite for Aldermore and eager to continue to provide straightforward financing solutions to UK SMEs and households.
“The new funds provide us with the opportunity to do even more to champion Britain's small businesses, the lifeblood of our economy.
“Our strong capital position also enables us to look at a number of new product and service launches to further meet the needs of our customers.
“I would like to thank all our investors for the confidence they have shown in Aldermore as we strive to do things differently.”
Funds advised by AnaCap Financial Partners LLP remain the lead investor in the Bank.
Toscafund and Lansdowne Partners will join other reputed institutional investors Morgan Stanley Alternative Investment Partners, Goldman Sachs Asset Management, Ohio Public Employees Retirement System and Honeywell Capital Management as investors.
