Key Takeaways
  • • Hamza Lemssouguer's London-based hedge fund Arini Capital Management, founded roughly four years ago, has become a dominant player in restructuring the debt of Europe's distressed companies, according to Bloomberg.
  • • Lemssouguer previously built his reputation at Credit Suisse through large trades in risky corporate debt, before the bank and he parted ways.
  • • Arini has been involved in multiple recent large refinancing battles, including those involving Patrick Drahi's Altice France and British e-commerce company Very Group.
  • • The firm's rise reflects intensifying competition in the market for reworking the debt of stressed European issuers.
Summary
Hamza Lemssouguer, once a prominent trader at Credit Suisse known for making sizeable trades on risky corporate debt, is now running his own hedge fund and applying a similar strategy, according to Bloomberg. His London-based firm, Arini Capital Management, did not exist four years ago but has quickly emerged as a dominant force in the increasingly competitive market for restructuring the debt of Europe's ailing companies.

Bloomberg reports that Arini has been involved in several recent high-profile refinancing negotiations. These include deals tied to tycoon-owned companies such as Altice France, controlled by Patrick Drahi, and British e-commerce retailer Very Group. The article characterizes the market for these distressed situations as increasingly cutthroat, with multiple funds competing for influence over outcomes.

The source article does not disclose specific deal values, fund size or assets under management, or performance figures for Arini, so those details cannot be confirmed from this report. Lemssouguer's departure from Credit Suisse and the bank's separation from him are noted, but the article provides no further detail on the circumstances.
