- • The firm, founded in 2021 by Hamza Lemssouguer, reported $22 billion in assets under management as of August 31, but those assets span multiple strategies and were not available to rescue the struggling portfolio.
- • Losses were concentrated in distressed telecom and media credits, including Altice International, Optimum Communications, Virgin Media and Brightspeed, with additional exposure to Aston Martin and Multi-Color.

Summary
Hamza Lemssouguer built Arini Capital Management into a $22 billion investment firm in roughly five years, but in October 2026 one of its core strategies was under severe strain. According to a October 30 Wall Street Journal investigation, Arini sold approximately $800 million in debt holdings over several weeks, partly to satisfy margin calls from banks. Its roughly $7 billion flagship fund had lost more than 20% during 2026 by mid-October.
Lemssouguer founded Arini in 2021 after working as a credit trader at Credit Suisse. The firm's strategy centered on distressed debt, particularly bonds of financially troubled issuers that could recover if their businesses stabilized. On October 21, the company confirmed $22 billion in assets under management as of August 31 and announced a new direct-lending fund targeting more than $4 billion in deployment, including anticipated borrowing. The firm noted that those assets were spread across multiple strategies rather than available as cash to support any single portfolio.
The flagship fund's losses stemmed from distressed telecommunications and media investments, including Altice International, Optimum Communications, Virgin Media and Brightspeed. Other exposures included Aston Martin and packaging company Multi-Color. By September, the flagship strategy was down approximately 15.7% for the year, and losses deepened in October as European corporate credit markets weakened.
The immediate pressure came from margin requirements. Arini reportedly faced margin calls connected to credit-default-swap indexes and other leveraged trades, and banks demanded additional collateral as the value of positions fell. Because distressed corporate debt becomes hard to sell when defaults or restructurings are feared, the fund sold relatively healthy, liquid bonds for which buyers were available, while retaining its troubled positions.
Arini's difficulties coincide with a broader global bond selloff, rising borrowing costs for heavily indebted companies, concerns over France's borrowing costs, and higher costs of default protection on CoreWeave debt. The Wall Street Journal report indicates that Arini's collateralized loan obligation strategies have performed relatively well and that the company has continued expanding its private-credit operations.
