Bitmain S-19j Pro miner purchase - December 2020 contract
Company: Marathon Digital
What the later record shows
Delivered late
The Q3 2021 10-Q says the full price was paid as of September 30, 2021 and that the 10,000 units were received after that date, which is past the September 2021 deadline. The later 10-K wording ('delivered in August/September 2021') conflicts, so confidence is medium.
“As of September 30, 2021, the Company has paid the entire purchase price under this agreement.”
