Antminer S19 Pro miners purchase from Bitmain
Company: Riot
What the later record shows
Delivered; the record does not say when
The 10-K/A says that by December 31, 2020 Riot had received all 1,040 of the model S19 miners, matching this 1,040-unit order. No passage gives the delivery date, so on-time versus late July 2020 cannot be determined.
“As of December 31, 2020, the Company had received 3,043 of the new miners, including all 1,040 model S19 miners and 2,003 model S19-Pro miners”
