Shares of Silvergate Capital plummeted Thursday after the bank delayed the filing of its annual 10-K report as it evaluates events that have happened since the end of 2022.

The company, which provides banking services to crypto businesses, was last lower by 45%, after falling as much as 48.8% earlier in the day. The move pulled its year-to-date loss to 57%.

Silvergate said in a filling Wednesday that it needs additional time for its accounting firm to complete certain audit procedures and that it’s “currently analyzing certain regulatory and other inquiries and investigations.”

Specifically, it cited the “sale of additional investment securities beyond what was previously anticipated” and the “impact that these subsequent events have on its ability to continue as a going concern.”

The bank noted that its preliminary, unaudited financial results for 2022, filed Jan. 17, included a net loss attributable to common shareholders of $948.7 million, compared with net income of $75.5 million in 2021.

Silvergate is has been facing several challenges since the end of last year, following the blowup of crypto exchange FTX. In January it suffered another 40% drop in a single day after reporting massive withdrawals in the fourth quarter, in light of the FTX collapse. Then in February the Department of Justice opened an investigation into the bank’s dealings with FTX and its sister company Alameda Research.

The move in its shares weighed on Signature Bank, which also banks crypto startups. Its stock hit a 52-week low intraday, and was recently down nearly 6%.

Coinbase also fell about 7%. The crypto services company said in a statement that has de minimis corporate exposure to Silvergate and that it’s no longer accepting or initiating payments to or from Silvergate.

The move did not have a big effect on cryptocurrencies, however. Bitcoin and ether were each hovering just below the flatline.
