The firm saw AUM hit £33.6bn in the period, rising to £34bn on July 12, and inflows for the quarter were £1bn.
John Ions, chief executive of Liontrust AM, said: "Liontrust has delivered a strong first three months of the financial year with positive net inflows.”
The update comes weeks after the firm pulled the initial public offering (IPO) of its sustainable investment trust after a lack of interest.
The group said although it had received significant support from private investors, the demand did not reach the minimum investment of £100m, as set out in the prospectus.
Liontrust announced the IPO in May this year, and said the trust would invest in 25 to 35 companies around the world that it deemed sustainable.
In the update this morning (July 14), Ions welcomed Quintin Price to the board of Liontrust.
Price, who spent ten years as head of alpha strategies at BlackRock, was most recently a senior adviser at Actis, a privately owned private equity, real estate, energy and infrastructure firm.
Ions said: “Quintin brings extensive experience, knowledge and insights having worked at a senior level in asset management, including at BlackRock, for more than 30 years.
“Quintin is a valuable addition as we seek to continue our growth and I and the rest of the board look forward to working with him."
