Facing losses stemming from the FTX collapse in November and regulatory inquiries on a number of fronts, Silvergate Capital (SI) on Wednesday evening said the filing of its annual report would be delayed.

The company further said the impact of the losses and regulatory issues call into question its ability to continue as a “going concern.” Shares are down 29% in after hours trading.

Among the largest holders of Silvergate stock are funds managed by State Street and BlackRock, both of whom have added to stakes in recent weeks. Also, Ken Griffin’s Citadel Securities last week disclosed 5.5% of “market making positions” in the shares.
