Independent auditor ratified
Company: Riot
What the later record shows
Not a promise: a reported event
The claim reports a ratification vote that had already occurred, so it is not a commitment. Its text gives no exact date. A later passage confirms Marcum audited fiscal 2019.
“The Audit Committee previously retained Marcum LLP to serve as the Company’s independent public accounting firm and to perform such audit services for the years ended December 31, 2018, 2019, 2020, 2021 and 2022.”
