CleanSpark (NASDAQ:CLSK) has purchased 60K Bitmain S21 miners, or the equivalent of 32 exahashes per second (EH/s), for a total of $193.2M, the company said Monday.

Delivery of the 60K units, which was acquired at $16.10 per terahash, is expected in April through June 2024.

The deal also includes a call option to buy an additional 100K machines at a fixed price of $16.00 per terahash until the end of the calendar year.

If CleanSpark (CLSK) exercises the full call option, its hashrate is expected to jump to ~50 EH/s from the current 10 EH/s, once all machines are deployed.

"We are ready to expand into the next bull market without the need to worry about an increase in machine prices, since the call purchase option acts as a hedge to this risk," said CleanSpark CEO Zachary Bradford.

CLSK slipped 1.2% in premarket trading.

Late last year, CleanSpark (CLSK) said it bought 4.4 EH/s of Antminer S21 miners.
