The combined arms reported higher levels of average funds under management and net inflows in excess of £4.9bn, which group managing director Bernard Kantor said was testament to its "strong franchise".
The UK business reported better results than last year, as Investec Wealth & Investment saw a 30.9% increase in adjusted operating profit. Over the year to 31 March 2013, pre-tax profits rose from £38.7m to £50.7m, following the migration of former Williams de Bröe assets onto the platform in August 2012.
The Williams de Bröe brand has disappeared and now is part of Investec Wealth & Investment.
Net inflows rose by £800m while funds under management were posted as £40.4bn, up from £34.8bn last year.
Elsewhere, Investec Asset Management saw net inflows of £4.1bn and growth in performance fees. Its total funds under management are £69.8bn, up from £61.6bn last year.
Its operating profit rose 4.8% over the same period, from £133.7m to £140.2m.
The group said realigning its business towards "low capital intensive businesses" over the past few years has resulted in a scaleable platform, allowing its asset management and wealth management businesses to continue to grow.
Investec added that increasing the conversion of non-discretionary to discretionary client mandates was bringing in higher management fees.
The group’s Specialist Banking division also saw a rise in pre-tax profit, up 30.1% from £186.2m to £242.3m during the year to 31 March.
Investec said the focus of the bank would remain on efficiency and balance sheet optimisation, in addition to growing the business organically and running down its legacy portfolios.
