Trading app provider Robinhood was subpoenaed by U.S. securities regulators late last year, according to a filing submitted by the company on Feb. 27.

In that filing, Robinhood said it received an investigative subpoena from the U.S. Securities and Exchange Commission (SEC) concerning various matters such as cryptocurrency listings, crypto custody practices, and platform operations.

The company said it received the subpoena in December 2022 following the collapse of FTX in November (and the collapse of other companies in the summer).

Robinhood said it could face sanctions if the SEC or any court determines it has not complied with securities regulations. The company also said that if its listed cryptocurrencies are determined to be securities, it could be prevented from supporting the trading of those assets. Furthermore, Robinhood said it could be forced to pay regulatory penalties and compensation to its users.

Robinhood made the above statements within its 10-K filing — a required annual report for publicly- and privately-traded companies. Though the filing concerns the fiscal year ending in December 2022, the filing was not submitted or publicized until today.
