Morgan Stanley Says It Lost Nearly $1 Billion Following Archegos DisasterStill, the firm managed to report net revenues of $15.7 billion for its first quarter.

Despite posting solid results for its first quarter, Morgan Stanley lost nearly $1 billion as a result of its partnership with Archegos Capital Management, according toCNBC.

The firm announced in an earnings call last Friday that it lost $644 million from a "credit event" for Archegos in addition to $267 million in trading losses. The combined $911 million loss was partly driven by Morgan Stanley's role as an underwriter on ViacomCBS shares. The firm had served as one of Archegos' prime brokers and oversaw a $3 billion stock offering that fell apart in March.

"We liquidated some very large single stock positions through a series of block sales culminating on Sunday night, March 28," Morgan Stanley CEO James Gorman reportedly said on the call with analysts. "That resulted in a net loss of $644 million, which represents the amount the client owed us under the transactions that they failed to pay us."

Gorman added that the firm made the decision to "to completely de-risk the remaining smaller long and short positions." In an effort to escape the risk as quickly as possible, Morgan Stanley incurred an "incremental loss of $267 million."

Last month, however, Archegos suffered a major setback when ViacomCBS — on which the family office had bet massively and tripled its shares in four months — saw its stock offering crumble. Brokers immediately scrambled to exit the positions on Archegos' behalf to stem their losses, but Morgan Stanley waited until the following Sunday to sell a block of the company's stock. Though the firm subsequently suffered losses, it still managed to report net revenues of $15.7 billion for its first quarter.
