Bitcoin miner Riot said there will be a delay in meeting its first quarter hashrate guidance of 12.5 EH/s due to damage from the winter storm that hit the U.S. in December and knocked miners offline.

In January, it mined 740 bitcoins, 12% more than in the previous month when it curtailed power due to the storm.

Of the 2.5 EH/s affected by damage to piping in two buildings, a total of 0.6 EH/s has been brought back online with 1.9 EH/s remaining.
