What the later record shows

How we checked this
Checked on October 11, 2026. The cited source supports part of this claim, but not all of it.
This proxy statement, dated before the October 19, 2021 meeting, shows that ratifying Marcum LLP as auditor for fiscal 2021 was proposed and recommended by the Board. It cannot show whether stockholders actually approved it, so if the claim describes a completed ratification, that part is not established here.
Confirmed in the source:
- Riot Blockchain's 2021 proxy statement put forward a proposal to ratify Marcum LLP as its independent registered public accounting firm for the fiscal year ending December 31, 2021
- Riot Blockchain's Audit Committee appointed and retained Marcum LLP to audit the company's financial statements for the fiscal year ending December 31, 2021
- Riot Blockchain's Board unanimously recommended that stockholders vote for ratifying Marcum LLP's appointment
We could not confirm this from the cited source:
- Riot Blockchain's stockholders actually ratified Marcum LLP's appointment for fiscal year 2021
That does not mean it is false — only that this source does not establish it, as of the date above. If we find a source that settles it, we will re-check and update this page.
What we did: Read our cached copy of SEC EDGAR (https://www.sec.gov/Archives/edgar/data/1167419/000107997321000934/riot_def14a.htm) in full (161,521 characters, retrieved September 13, 2026) and checked each assertion in the claim against it.
