AHR advises and manages $2bn (£1.55bn) of assets and employs over 150 people. It will be rebranded as Titan Wealth International.

The cost of the deal has not been disclosed.

AHR provides bespoke wealth management and cross-border financial advice for expatriates. It has offices in Mauritius, Malaysia, Cyprus, the UK, and Australia.

Titan said the acquisition demonstrated its ambition of building a "vertically integrated, client-focused financial services offering across multiple jurisdictions."

The deal takes Titan’s assets under advice, under management and on platform to over £20bn.

Andrew Fearon, joint CEO at Titan Wealth, said: “This acquisition is an exciting development for our clients, reflecting our dedication to delivering an integrated financial services offering on a global scale. We look forward to working closely with the talented team at AHR to build our proposition internationally, whilst helping them expand their services to both existing and future clients.”

Titan is currently involved in a spat with Berkshire Financial Planner Tavistock which terminated its 10-year strategic investment partnership with the firm earlier this month.

The surprise axing of the tie-up, agreed in June 2021, was issued to the stock market earlier this month.

In the announcement Tavistock said: "This follows a sustained period of unacceptable performance by Titan."

Titan subsequently issued a counter statement accusing Tavistock of “serious wrongful conduct” in ending the deal under which Titan managed Tavistock funds.

Titan says it has a claim for damages after Tavistock ended the investment agreement.
