Two US bondholders, Arini Capital Management and Tresidor Investment Management, have filed an application with a New York court seeking authorization to collect evidence for a legal challenge in the UK against Aston Martin's debt restructuring. The application asks the court to compel BlackRock's HPS Investment Partners, the UK arm of Authentic Brands Group, and advisory firms Moelis & Co and Lazard to provide documents and testimony. The bondholders argue that a £450 million debt arrangement between Aston Martin, HPS, and Authentic Brands prejudiced existing creditors and transferred some of the company's most valuable assets beyond the reach of existing creditors.
